                           SILICON VALLEY BANCSHARES

                 INFORMATION CONCERNING THE PROXY SOLICITATION
 
GENERAL
 
    This Proxy Statement is furnished in connection with the solicitation of the
enclosed Proxy by, and on behalf of, the Board of Directors of Silicon Valley
Bancshares, a Delaware corporation and bank holding company (the "Company") for
Silicon Valley Bank (the "Bank"), for use at the 2000 Annual Meeting of
Stockholders of the Company to be held in the Great America Ballroom at the
Santa Clara Convention Center, 5001 Great America Parkway, Santa Clara,
California 95054, ON THURSDAY, APRIL 20, 2000 AT 4:00 P.M., local time and at
all postponements or adjournments thereof (the "Meeting"). Only Stockholders of
record on February 22, 2000 (the "Record Date") will be entitled to vote at the
Meeting and any postponements or adjournments thereof. At the close of business
on the Record Date, the Company had 22,953,371 outstanding shares of its $.001
par value Common Stock (the "Common Stock").
 
    The Company's principal executive offices are located at 3003 Tasman Drive,
Santa Clara, CA 95054 and its telephone number at that location is
(408) 654-7400.
 
VOTING
 
    Stockholders of the Company's Common Stock are entitled to one vote for each
share held, except that in the election of directors, each stockholder has the
right to invoke cumulative voting, which entitles each stockholder to as many
votes as shall equal the number of shares held by such stockholder multiplied by
the number of directors to be elected. A stockholder may cast all of his or her
votes for a single candidate or distribute such votes among as many of the
candidates he or she chooses (up to a maximum of the number of directors to be
elected). However, no stockholder shall be entitled to cumulate votes (in other
words, cast for any candidate a number of votes greater than the number of
shares of stock held by such stockholder) for a candidate unless such
candidate's or candidates' names have been properly placed in nomination prior
to the voting in accordance with Section 6 of the Certificate of Incorporation
of the Company and the stockholder (or any other stockholder) has given notice
at the meeting prior to the voting of the stockholder's intention to cumulate
votes. If any stockholder has given such notice, all Stockholders may cumulate
their votes for candidates properly placed in nomination. If cumulative voting
is properly invoked, the Proxy Holders are given discretionary authority under
the terms of the Proxy to cumulate votes represented by shares for which they
are named Proxy Holders as they see fit among management's nominees in order to
assure the election of as many of such nominees as possible.
 
    Article Two of the Bylaws of the Company governs nominations for election of
members of the Board of Directors, as follows: nominations for election of
members of the Company's Board of Directors may be made by the Board of
Directors or by any stockholder of any outstanding class of capital stock of the
Company entitled to vote for the election of directors. Notice of intention to
make any nominations shall be made in writing and shall be delivered or mailed
to the Secretary of the Company no later than the close of business on the
sixtieth (60th) day nor earlier than the close of business on the ninetieth
(90th) day prior to the meeting; provided, however, that in the event that less
than sixty-five (65) days notice of the meeting is given to Stockholders, notice
by the stockholder to be timely must be so delivered not later than
 
                                       1

<PAGE>
the close of business on the seventh (7th) day following the date of mailing
notice of the meeting to stockholders. Such notification shall contain the
following information to the extent known to the notifying stockholder: (a) the
name and address of each proposed nominee; (b) the principal occupation of each
proposed nominee; (c) the number of shares of Common Stock of the Company owned
by each proposed nominee; (d) the name and residence address of the notifying
stockholder; and (e) the number of shares of Common Stock of the Company owned
by the notifying stockholder. Nominations not made in accordance herewith may,
at the discretion of the Chairman of the meeting, be disregarded and upon the
Chairman's instructions, the Inspector of Election can disregard all votes cast
for each such nominee.
 
QUORUM; ABSTENTIONS; BROKER NON-VOTES
 
    The required quorum for the transaction of business at the Annual Meeting is
a majority of the shares of Common Stock issued and outstanding on the Record
Date. Shares that are voted "FOR", "AGAINST" or "WITHHELD FROM" a matter are
treated as being present at the meeting for purposes of establishing a quorum
and are also treated as shares "represented and voting" at the Annual Meeting
(the "Votes Cast") with respect to such matter.
 
    While there is no definitive statutory or case law authority in Delaware as
to the proper treatment of abstentions, the Company believes that abstentions
should be counted for purposes of determining the presence or absence of a
quorum for the transaction of business, but should not be counted as Votes Cast
with respect to a proposal, since the stockholder has expressly declined to vote
on such proposal. In the absence of controlling precedent to the contrary, the
Company intends to treat abstentions in this manner.
 
    Similarly, broker non-votes will be counted for purposes of determining the
presence or absence of a quorum for the transaction of business, but will not be
counted for purposes of determining the number of Votes Cast with respect to the
proposal on which the broker has expressly not voted.
 
    Accordingly, abstentions and broker non-votes will not affect the outcome of
the voting on a proposal that requires a majority of the Votes Cast (such as
approval of the amendment to the 1997 Equity Incentive Plan).
 
REVOCABILITY OF PROXIES
 
    Any person giving a Proxy in the form accompanying this Proxy Statement has
the power to revoke the Proxy at any time prior to its use. A Proxy is revocable
prior to the Meeting by delivering either a written instrument revoking it or a
duly executed Proxy bearing a later date to the Secretary of the Company or to
the Company's transfer agent. Such Proxy is also automatically revoked if the
stockholder is present at the Meeting and votes in person.
 
SOLICITATION
 
    This solicitation of Proxies is made by, and on behalf of, the Board of
Directors of the Company. The Company will bear the entire cost of preparing,
assembling, printing, and mailing Proxy materials furnished by the Board of
Directors to stockholders. Copies of Proxy materials will be furnished to
brokerage houses, fiduciaries and custodians to be forwarded to the beneficial
owners of the Company's Common Stock. In addition to the solicitation of Proxies
by use of the mail, some of the officers, directors and regular employees of the
Company and the Bank may (without additional compensation) solicit Proxies by
telephone or personal interview, the costs of which the Company will bear.
 
    Unless otherwise instructed, each valid returned Proxy that is not revoked
will be voted in the election of directors "FOR" the Company's nominees to the
Board of Directors, "FOR" approval of the amendment to the Company's 1997 Equity
Incentive Plan, "FOR" ratification of the appointment of KPMG LLP as the
Company's independent auditors, and at the Proxy Holders' discretion on such
other
 
                                       2

matters, if any, as may properly come before the Meeting or any postponement or
adjournment thereof (including any proposal to adjourn the Meeting).
 
 
                                PROPOSAL NO. 1
                             ELECTION OF DIRECTORS
          THE BOARD OF DIRECTORS RECOMMENDS A VOTE "FOR" ALL NOMINEES
 
    The Company's Bylaws currently provide for a range of from eight (8) to
fifteen (15) directors and permit the exact number to be fixed by the Board of
Directors. Effective as of April 20, 2000, the Board of Directors has fixed the
exact number of directors at nine (9).
 
NOMINEES FOR DIRECTOR
 
    All Proxies will be voted "FOR" the election of the following nine
(9) nominees recommended by the Board of Directors, unless authority to vote for
the election of directors (or for any particular nominee) is withheld. All of
the nominees have served as directors of the Company since the last Annual
Meeting of Stockholders, except for Kenneth P. Wilcox. All incumbent directors
are nominees for re-election to the Board. If any of the nominees should
unexpectedly decline or be unable to act as a director, the Proxies may be voted
for a substitute nominee designated by the Board of Directors. The Board of
Directors has no reason to believe that any nominee will become unavailable and
has no present intention to nominate persons in addition to or in lieu of those
listed below. Directors of the Company serve until the next annual meeting of
stockholders or until their successors are elected and qualified.
 
    The names and certain information about each of the Company's nominees for
director as of the Record Date are set forth below.

                 REPORT OF THE EXECUTIVE COMMITTEE OF THE BOARD
                           ON EXECUTIVE COMPENSATION
 
    THE REPORT OF THE EXECUTIVE COMMITTEE (THE "COMMITTEE") 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 (THE "EXCHANGE ACT"), EXCEPT TO THE EXTENT
THAT THE COMPANY SPECIFICALLY INCORPORATES THE INFORMATION CONTAINED IN THE
REPORT BY REFERENCE, AND SHALL NOT OTHERWISE BE DEEMED FILED UNDER SUCH ACTS.
 
    Decisions regarding compensation of the Company's executive officers,
including those related to stock and stock options, are considered by the full
Board of Directors, based upon the recommendations and analysis performed by the
Executive Committee (the "Committee"), currently composed of Mr. Kelleher,
Chair, and Directors Burns, Dean and Wells. Since the Committee is responsible
for setting the Chief Executive Officer's compensation (subject to approval by
the full Board), Mr. Dean refrains from participating in any discussions of the
Committee relating to his performance or compensation. During 1999, the Board of
Directors did not modify or reject in any material way any action or
recommendation by the Committee.
 
KEY PRINCIPLES
 
    The Committee has adopted the following principles to use for guidance in
setting compensation:
 
    -  PAY COMPETITIVELY
 
       - The Committee maintains a philosophy that executive compensation levels
         should be competitive relative to those found in other financial
         institutions of comparable asset size. In that way, the Company can
         attract and retain highly-qualified executives critical to the
         Company's long-term success.
 
       - Consistent with this philosophy, the Committee regularly obtains
         information regarding executive salary levels in the financial
         institutions industry through various sources, including compensation
         surveys conducted by banking industry associations and independent
         compensation consultants.
 
       - The Committee attempts to set base compensation in the 75(th) to
         115(th) percentile range of market pay targets which are established
         through research of comparable positions in related industries in the
         marketplace. An executive's actual base compensation within the
         percentile range depends on the executive's proficiency level for the
         particular position.
 
       - The Committee strives to reward performance that creates value for the
         Company's stockholders.
 
    -  TIE INCENTIVE COMPENSATION TO COMPANY FINANCIAL PERFORMANCE
 
       - Total incentive compensation (the "incentive compensation pool") paid
         to the Company's officers under the 1999 incentive compensation
         program, as in the prior year, was calculated using a customized
         version of a financial model called Economic Value
         Added-Registered Trademark-, or EVA-Registered Trademark-(1).
         EVA-Registered Trademark- is a more accurate measure of true economic
         profit than net income, as it takes into account how effectively
         capital is being used to produce the profit. By using
         EVA-Registered Trademark- to calculate the incentive compensation pool,
         sustained, continuous improvement in the Company's financial
         performance is rewarded, as the incentive compensation pool increases
         with improvement in the Company's performance from the prior year to
         the then-current year.
 
------------------------
 
(1)  EVA-Registered Trademark- is a registered trademark of Stern Stewart & Co.
 
                                       9

<PAGE>
       - Once the amount in the incentive compensation pool was determined
         (based on the Company's 1999 EVA-Registered Trademark- performance),
         the Company allocated such amount among eligible officers in the
         Company. The method for allocation involved:
 
           (1) determining a "target" incentive amount (based on the Company's
               1999 EVA-Registered Trademark- performance), tied to officer
               level in the Company,
 
           (2) determining any additional "discretionary" amount that should be
               paid to each officer, and
 
           (3) ensuring on a Company-wide basis, that the aggregate of all
               bonuses paid to eligible officers does not exceed the incentive
               compensation pool amount.
 
       - Individual performance is based on attainment of goals set at the
         beginning of the year. Generally, the goals of officers in the Company
         are tied to their respective divisions' results, including generation
         of income (for the lending divisions) and client service levels (for
         the support divisions).
 
1999 MARKET SURVEYS
 
    -  EXECUTIVE OFFICERS
 
       - A review of the Company's executive compensation was completed by an
         independent compensation consultant (CompAnalysis) in July 1999. In
         reviewing the 1999 base salary program, the compensation consultant
         reviewed compensation data from fifteen data sources covering the
         financial services industry. Included among the data sources were the
         "1998 Executive Compensation Database--Financial Services Report" from
         Towers Perrin, the "1998 Financial Institutions Benchmark Survey" from
         Watson Wyatt, and the "1998 Job Pricing Survey--Banking Industry" from
         the Hay Compensation Report. The competitive market data was updated to
         reflect projected July 1, 1999 compensation levels, assuming a 4%
         annualized increase for base salary. The compensation consultant
         "matched" specific Bank officers as closely as possible with officers
         from the data sources with similar functional responsibilities. Also,
         where possible, the compensation consultant "matched" Bank officers
         with their counterparts in institutions of similar asset size (as the
         Bank) and institutions located in the same geographic area as the
         Bank's. The compensation consultant concluded that the annual base
         compensation for executive officers Baldwin, Kamm, Kellogg, Verissimo
         and Wilcox was significantly below that for related positions included
         in the surveyed job descriptions. Based on this information, base
         salaries for these individuals were increased to $157,500, $175,000,
         $202,500, $157,500, and $215,002, respectively, effective July 1, 1999.
 
    -  CHIEF EXECUTIVE OFFICER OF THE COMPANY
 
       - The July 1999 compensation consultant review (described above in "1999
         Market Surveys--Executive Officers") included data on chief executive
         officer compensation. The compensation consultant concluded that
         Mr. Dean's target cash compensation for 1999 was below that of chief
         executive officers included in the competitive market data. Based on
         this information, Mr. Dean's base salary was increased from $350,000 to
         $400,000, effective July 1,1999.
 
INCENTIVE COMPENSATION PAID BASED ON 1999 COMPANY PERFORMANCE
 
    -  ACTUAL INCENTIVE COMPENSATION PAYMENTS
 
       -  EXECUTIVE OFFICERS. In allocating the incentive compensation pool
          among eligible officers in the Company, the Committee reviewed the
          Company's consolidated EVA-Registered Trademark- results, as well as
          actual performance for such officers in 1999. As to Messrs. Baldwin,
          Verissimo, and Kellogg and Ms. Kamm, the Committee reviewed their
          respective divisions' financial performance, as
 
                                       10

<PAGE>
          well as other significant contributions made by such divisions (such
          as development of new financial products or expansion into other
          geographic regions). In regard to setting Mr. Wilcox's cash incentive
          amount, the Committee considered the Bank's strong financial
          performance in 1999 (exceeding target goals set in the first quarter
          of 1999).
 
       -  CHIEF EXECUTIVE OFFICER OF THE COMPANY. In determining Mr. Dean's 1999
          cash incentive compensation, the Committee reviewed his actual
          performance in 1999 in comparison to his performance plan set in the
          first quarter of 1999. The Committee reviewed the Company's strong
          financial performance in 1999 (exceeding target goals set in the first
          quarter of 1999), in setting Mr. Dean's incentive compensation.
 
    -  RETENTION PROGRAMS
 
       -  EXECUTIVE OFFICERS. In addition to cash incentive payments made to
          executive officers for 1999 performance, in the first quarter of 2000,
          the Company allocated interests in the Company's 2000 retention
          program to certain executive officers. Under the 2000 retention
          program, the Company allocates interests in future distributions from
          the Company's investments in selected venture capital funds and direct
          equity investments, and in warrant income the Company realizes from
          the exercise and sale of all warrants taken in 1999. Specifically, the
          2000 retention program allocates interests in distributions from 20%
          of the Company's existing direct equity investment program ($400,000
          in the aggregate), 20% of the existing commitments under the Company's
          venture capital investment program ($3,100,000 in the aggregate), and
          8% of all income the Company realizes from the exercise and sale of
          warrants taken in 1999. In short, the interests to be allocated are
          derived from 20% of the distributions received by the Company in
          selected venture capital fund investments and direct equity
          investments, and 8% of income realized from warrants taken in 1999.
          Under this program, the Company granted executive officers the
          following interests: Mr. Wilcox, a $155,000 interest; Mr. Kellogg, a
          $135,000 interest; Mr. Verissimo, a $90,000 interest; Mr. Baldwin, a
          $90,000 interest, and Ms. Kamm a $80,000 interest.
 
           The executive officers' interests are not in the venture capital
           funds or direct equity investments themselves, but rather, in future
           distributions to the Company from such funds or investments. The
           Company's original investment in the subject funds and direct equity
           investments (the distributions from which the executive officers have
           an interest) generally have been made in the last couple of years.
           Accordingly, and given historical data (for example, where
           distributions from the venture capital funds typically are made in
           the fifth to tenth years after origination of the funds), the
           Committee views the retention program as a long-term retention
           program for executives. The 2000 retention program is similar to the
           1998 venture capital retention program (where the Company granted
           executive officers interests in distributions from a $850,000 pool of
           venture capital investments earmarked for the 1998 program) and the
           1999 retention program (where the Company granted executive officers
           interests in distributions from a $1,600,000 pool of venture capital
           investments earmarked for the 1999 program). Together with other
           compensation benefits that vest over a stated period of time (such as
           Company stock options), the Committee believes the retention programs
           serve to retain key executives, while at the same time serve to
           provide some diversification to executives' investment portfolios.
 
       -  CHIEF EXECUTIVE OFFICER OF THE COMPANY. In the first quarter of 2000,
          the Company allocated to Mr. Dean a $265,000 interest in the Company's
          2000 retention program described above.
 
                                       11

<PAGE>
    -  EMPLOYEE STOCK OWNERSHIP PLAN
 
       - The Company also made payments to employees under its employee
         retirement plans, including to executive officers. See discussion in
         "Retirement Plans" below regarding payments to executives under the
         Company's qualified defined contribution plans.
 
TAX CONSEQUENCES
 
    To the extent determinable and as one of the factors in its consideration of
compensation matters, the Committee considers the anticipated tax treatment to
the Company and to the executives of various payments and benefits. The
Committee will consider various alternatives to preserving the deductibility of
compensation payments (in particular, pursuant to Section 162(m) of the Internal
Revenue Code) to the extent reasonably practicable and to the extent consistent
with its other compensation objectives. No executive officer received cash
compensation in excess of $1 million during 1999. The Committee adopted
limitations on the number of shares that may be subject to awards granted under
the 1989 Stock Option Plan and the 1997 Equity Incentive Plan during any one
calendar year to an individual so that compensation derived from stock options
granted under such plans would qualify as "performance-based" compensation
within the meaning of Section 162(m) and would therefore be deductible by the
Company without regard to the $1 million limitation.

EXECUTIVE COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
    In 1999, the Executive Committee performed all compensation functions of the
Board of Directors, including administration of the Company's stock-based
employee benefit plans. (See discussion below under "Board Committees and
Meeting Attendance" for additional information on the Executive Committee.) The
Executive Committee is currently chaired by Mr. Daniel J. Kelleher, with
Directors Wells, Burns, and Dean serving as members. With the exception of
Mr. Dean, none of the aforementioned persons has ever been an officer or
employee of the Company or the Bank. Mr. Dean refrains from participating in any
Committee discussions related to his performance or compensation.

(1)  Includes amounts deferred at the election of the executive officer.
 
(2)  Amounts in this column represent (a) relocation costs incurred by the
     executive officer and reimbursed by the Bank, as well as (b) premiums for
    supplemental long-term disability coverage provided by the Bank. Amounts for
    the years shown are not reflected if the total value of perquisites paid to
    the executive officer during a fiscal year did not exceed, in the aggregate,
    the lesser of $50,000 or 10% of the individual's salary plus bonus in the
    subject year. Amount reflected for Mr. Wilcox in 1998 represents relocation
    costs in the amount of $84,302, as well as $50,750 for uncharged interest by
    the Company in connection with two interest-free relocation loans made by
    the Company to Mr. Wilcox (see discussion in "Certain Relations and Related
    Transactions"). Amounts reflected for Mr. Wilcox in 1999 represents $47,750
    for uncharged interest by the Company in connection with such loans. The
    uncharged interest was calculated by assuming an interest rate of 6.00%.
 
(3)  As of December 31, 1999, Mr. Dean held 12,500 unvested restricted shares of
     the Company's Common Stock (10,000 granted on January 18, 1996, and 5,000
    granted on August 16, 1999 of which 2,500 vested immediately), with a market
    value of $618,750. Market value is based on the $49.50 per share closing
    market price of the Company's Common Stock on the National Association of
    Securities Dealers Automated Quotation/National Market on December 31, 1999,
    the last trading day of 1999. Holders of restricted stock have rights
    equivalent to those of other stockholders, including voting rights and
    rights to dividends. 10,000 of Mr. Dean's shares vested on January 17, 2000,
    and 2,500 will vest on August 14, 2000, subject to earlier termination on a
    "Covered Termination" following a "Change in Control" (as defined). See
    "Termination Agreements" below. Amount reflected for Mr. Dean represents the
    value of the 5,000 shares (granted on August 16, 1999), based on the market
    price on the date of grant ($25.125).

(4)  The numbers in this column reflect shares of Common Stock underlying
     options. The numbers have been adjusted to reflect shares following a
    two-for-one stock split (effected in May 1998). No Stock Appreciation Rights
    ("SARs") were awarded during the years 1997 through 1999.
 
(5)  Amounts in this column include employer contributions to the Bank's
     combined 401(k) and Employee Stock Ownership Plan, and Money Purchase
    Pension Plan (see discussion under "Retirement Plans"). Amounts in this
    column also include distributions received under the Company's retention
    plans. Under the 1998 and 1999 retention plans, the Company granted to
    executives, interests in the venture capital investment program (under which
    the Company invests in venture capital funds for its own account). Interests
    are not in the venture capital funds themselves, but rather, in future
    distributions from such funds. The 2000 retention plan includes not only
    interests in the Company's venture capital investments, but also in the
    Company's direct equity investments and warrant income realized on warrants
    taken in 1999.
 
    The following charts breakdown the amounts in this column, and also shows
the allocations made under the retention plans during each of the following
years:

------------------------
 
(1)  Consists entirely of options granted pursuant to the Company's 1997 Equity
     Incentive Plan (the "Plan"). The Plan provides for administration of the
    Plan by the Board of Directors of the Company, or by a committee thereof to
    which the Board of Directors has delegated authority to administer the Plan
    (the "Administrator"). The Administrator designates the persons to be
    granted options, the type of option, the number of underlying shares, the
    exercise price, the date of grant and the date options become exercisable.
    The Administrator also has broad discretion to amend outstanding options or
    to effect repricings. These options were granted at 100% of the fair market
    value of the Company's Common Stock on the date of grant. The option grants
    vest ratably over four years and expire ten years from the date of grant.
    Upon a "Change in Control" of the Company or the Bank, the options will
    become fully exercisable. See "Termination Agreements" below. In
    October 1997, the Board of Directors voted to permit assignability of
    non-qualified stock options granted under the Plan to immediate family
    members, family trusts, and similar entities. Any options so assigned will
    continue to be reported in this table and in the option exercises table (see
    "Table 3" below) as if still held by the Named Officer.
 
(2)  Based on options to purchase an aggregate of 520,000 shares of the
     Company's Common Stock granted to certain employees during 1999 under the
    1997 Equity Incentive Plan and the 1989 Stock Option Plan.
 
(3)  Represents the potential net realizable dollar value of the option grants,
     i.e., the market price of the underlying shares (adjusted for the assumed
    annual stock appreciation rates of 5% and 10%, respectively, with the
    assumed rates compounded annually over the ten-year term of the options),
    minus the aggregate exercise price of the options. The stock price
    appreciation rates are mandated by SEC rules and do not represent the
    Company's estimate of future stock prices.

(1)  Consists entirely of stock options. No stock appreciation rights ("SARs")
     have been awarded to date. In October 1997, the Board of Directors voted to
    permit assignability of non-qualified stock options granted under the 1997
    Equity Incentive Plan to immediate family members, family trusts and similar
    entities. Any options so assigned will continue to be reported in this table
    as if still held by the Named Officer, and exercises by or on behalf of such
    assignees are also reflected as exercises by the Named Officer.
 
(2)  Represents the market price of the underlying securities on the date of the

    Company's Common Stock on the National Association of Securities Dealers
    Automated Quotation/National Market on December 31, 1999, less the exercise
    price.
 
RETIREMENT PLANS
 
    The Bank has two defined contribution plans: (1) the Silicon Valley Bank
401(k) and Employee Stock Ownership Plan (the "401(k)" and "ESOP") (a qualified
profit sharing plan under the Internal Revenue Code [the "IRC"]) and (2) the
Silicon Valley Bank Money Purchase Pension Plan (the "MPP") (a qualified money
purchase pension plan under the IRC). The Company matches 100% of employee-
deferred salary contributions to the 401(k), up to a maximum contribution of
$1,000 per year per employee. The Company makes contributions to the ESOP and
MPP using a compensation-based formula (subject to certain limitations on
compensation under the IRC). ESOP contributions are discretionary based on the
profitability of the Company, are invested primarily in the Company's Common
Stock and may not exceed 10% of eligible employees' base compensation. In 1999,
the ESOP contribution was 10% of eligible compensation as a result of the
Company's surpassing its stretch performance goal. MPP contributions are
guaranteed at 5% of eligible compensation and are invested at the participant's
direction.
 
                            TERMINATION ARRANGEMENTS
 
    The Bank entered into Termination Agreements ("Termination Agreements") with
certain executive officers, including Named Officers Baldwin, Dean, Kamm,
Kellogg, Verissimo, and Wilcox on August 12, 1998. These Termination Agreements
superseded other agreements then in effect (with those agreements having expired
on August 11, 1998). The Termination Agreements provide for severance pay and
continuation of certain benefits if the executive's employment is terminated
following a "Change in
 
                                       17

<PAGE>
Control" (defined below). The Termination Agreements were approved by
disinterested members of the Boards of Directors of the Company and the Bank
during 1997 (but effective August 1998 following expiration of the
then-operative Agreements).
 
    TERMINATION FOLLOWING A CHANGE IN CONTROL. In order for an executive to
receive benefits under the Termination Agreements following a Change in Control,
the executive must be terminated involuntarily without cause or constructively
terminated within 24 months following the Change in Control (a "Covered
Termination"). Also, benefits will be given to executives only following a
Change in Control that involves payments to stockholders in excess of two times
the then book value of the Company. (This reflects a change from the agreements
that expired in August 1998, where benefits would be paid for sales over one
times book value.)
 
    Under the Termination Agreements, a "Change in Control" will be deemed to
have occurred in any of the following circumstances:
 
        (1) the acquisition of 50% or more of the outstanding voting stock of
    the Company by any person or entity, with certain exceptions for employee
    benefit plans of the Company or the Bank;
 
        (2) the acquisition of 25% or more of the outstanding voting stock of
    the Company by any person or entity and a change in the composition of the
    Board during the following 12 months such that those persons serving as
    directors immediately prior to the share acquisition, and those new
    directors elected by a vote of at least two-thirds of the directors of the
    Company, cease to make up at least 60% of the directors of the Company;
 
        (3) a merger or consolidation of the Company with any other corporation,
    other than a merger or consolidation in which the stockholders of the
    Company immediately prior thereto continue to own more than 50% of the
    outstanding voting stock of the surviving entity; or
 
        (4) the complete liquidation of the Company or the Bank, or disposition
    of all or substantially all of the Company's or the Bank's assets.
 
    A constructive termination is deemed to have occurred if the executive
resigns in writing following a reduction in the executive's then annual base
salary, upon a 15% reduction in the executive's annual compensation (base salary
plus bonus), upon a material reduction in the executive's responsibilities, or
upon a relocation by more than 50 miles of the principal place at which the
executive works.
 
    Under the Termination Agreements, the amount of severance benefits payable
to an executive whose employment is terminated during the 24 months following a
Change in Control is dependent upon the "transaction price multiple" of the then
book value of the Company or the Bank. As the transaction price multiple of book
value increases above 2.0, the severance benefit (the "Severance Benefit")
(represented as a multiple of the executive's annual base salary) increases.
(Under the agreements that expired in August 1998, the severance benefit was
tied to the executive's total annual compensation [base salary plus bonus] and
the Severance Benefit increased as the transaction price multiple of book value
increased above 1.0.)
 
    The percentage payout of the Severance Benefit is on a sliding scale tied to
termination date. If the termination date is within 12 months following the
Change in Control, then 100% of the Severance Benefit will be paid. However,
between 12 months and 24 months following a Change in Control, a declining
percentage will be paid, with 75% of the Severance Benefit being payable for
terminations 15 months following a Change in Control and 0% being payable for
terminations 24 months following a Change in Control. Finally, all outstanding
options (representing interests in the Company's Common Stock) will become
immediately and fully vested (and may be exercised) upon a Change in Control,
and all restrictions upon any restricted Company stock will lapse immediately
and all such shares will become fully vested, generally (upon a Covered
Termination following a Change in Control).
 
                                       18

<PAGE>
    In linking the amount of termination payments within 24 months following a
Change in Control to the transaction price multiple of book value, the Boards of
Directors of the Company and the Bank underscored their view that management
should be rewarded correspondingly for increased stockholder value. Therefore,
the amount of severance payments to executives under the Termination Agreements
increases in direct proportion to increases in value realized through a Change
in Control of the Company or the Bank. Conversely, sale of the Company or the
Bank for less than 2.0 times book value would result in no cash payout to
executives under the Termination Agreements, although they would still be
entitled to acceleration of vesting.
 
    The severance program approved by the Boards of Directors of the Company and
the Bank includes certain non-executive Bank officers as well. The amount of
severance benefits payable to officers below the executive level is likewise
dependent upon the "transaction price multiple" described above. However,
non-executive bank officers receive severance payments for any sale of the
Company or Bank for one times book value and above. Under the program for
non-executive officers, as the grade level of the officer in the Bank increases,
the multiple of the officer's base salary used in determining the severance
benefit increases.
 
    LIMITATION ON SEVERANCE PAYMENTS.  To the extent that the severance payments
otherwise called for by the Termination Agreements would trigger "golden
parachute" tax treatment pursuant to Section 280(g) and/or Section 4999 of the
Internal Revenue Code, the payments will be reduced (including by executive
officers' electing to make payment to third-party charitable organizations) to
the largest amount that the employee determines would result in maximizing the
employee's net proceeds (after taking into account the payment of any applicable
taxes, including excise taxes).
 
DEAN AND KELLOGG AGREEMENTS RELATING TO GARAGE.COM-TM-
 
    INTRODUCTION.  In March 1998, the Company made an equity investment (the
"Initial Investment") in garage.com-TM-, an internet company that matches
entrepreneurs with investors. To further strengthen relationships between the
founders, advisors and investors in garage.com-TM-, on the one hand, and the
Bank, on the other, Mr. Dean agreed to serve as a director for garage.com-TM-.
 
    As a director for garage.com-TM-, Mr. Dean was offered the right to purchase
shares of common stock in garage.com-TM-. Mr. Dean assigned the right to the
Company. The Company exercised this stock purchase right (the "Subsequent
Investment").
 
    MESSRS. DEAN AND KELLOGG'S GARAGE.COM-TM- AGREEMENTS. The Board of Directors
believes that Mr. Dean's service as a director for garage.com-TM- indirectly
will provide value to the Company. Accordingly, the Company entered into an
agreement with Mr. Dean relating to garage.com-TM- on August 12, 1998. The
Company entered into a similar agreement with Mr. Kellogg, in recognition of
Mr. Kellogg's support of Mr. Dean in garage.com-TM- board matters. Under these
two agreements, as amended, Messrs. Dean and Kellogg each hold a twenty-five
percent (25%) interest in the Subsequent Investment.
 
FORRESTER CONSULTING AGREEMENT
 
    James F. Forrester resigned as Executive Vice President of the Company and
the Bank, effective February 28, 1999. The Bank and Mr. Forrester entered into a
consulting agreement, effective March 1, 1999, pursuant to which Mr. Forrester
served as a consultant to the Bank until February 28, 2000. Under the consulting
agreement, Mr. Forrester received $8,500 a month for his services as a
consultant. All stock options held by Mr. Forrester continued to be outstanding
and vested in accordance with their respective terms until expiration of the
consulting term.

                            DIRECTOR COMPENSATION(1)
 
    In August 1998, the Board approved the director compensation program for
outside directors for 1999-2000 service, as well as 2000-2001 service, on the
Board. The program provides for a grant to each outside director of options to
purchase 6,000 shares of the Company's Common Stock (made on August 4, 1998 at
an exercise price of $30.063 per share), with the first 3,000 shares subject to
the option scheduled to vest on the date immediately following the Company's
1999 Annual Meeting (subject to the director's re-election to the Board) and the
remaining 3,000 shares subject to the option scheduled to vest on the date
immediately following the Company's 2000 Annual Meeting (subject to the
director's re-election to the Board). On September 17, 1998, outside director
Jackson, who was appointed to the Board in August 1998, was granted an option to
purchase 6,000 shares (and on such terms, including exercise price) as granted
to the other directors the previous month.
 
    In January 1999, the Board approved a grant to each outside director, except
for Mr. Jackson, of options to purchase 1,000 shares of the Company's Common
Stock (made on January 21, 1999 at an exercise price of $17.875 a share), with
the shares scheduled to vest immediately following the Company's 1999 Annual
Meeting (subject to the director's re-election to the Board). Mr. Jackson was
granted options to purchase 1,500 shares with the same terms as those described
immediately above. The Board believed that Mr. Jackson should be awarded the
additional options to compensate for the exercise price of the options to
purchase 6,000 shares granted in September 1998 (as described above) being set
at a higher price than the then market price of the Company's stock, to keep
Mr. Jackson's grant consistent with the 1999-2000 compensation program.
 
    In January 2000, the Board approved an amendment to the director
compensation program for outside directors for 2000-2001 service on the Board.
The program provides each director with two alternatives for compensation for
2000-2001 service. Under the first alternative, the director may choose to
retain the 3,000 options which will vest on the date immediately following the
Company's April 2000 Annual Meeting. Under the second alternative, the director
may choose that one-half of the options vesting in 2000 (e.g., 1,500 options) be
cancelled, and in exchange for the cancelled options, the director receives a
$16,500 interest in the Company's 2000 Director Compensation Program (which is
part of the 2000 Retention Program pool described above under "Report of the
Executive Committee of the Board on Executive Compensation"). On or before the
date of the March 2000 Board meeting, each director must elect the first or
second alternative for compensation.
 
    Mr. Gay and Mr. Ferrari, both former directors, served as advisory directors
to the Board during the 1999-2000 term. In recognition of their advisory role,
the Company paid Mr. Gay and Mr. Ferrari $3,750 per meeting attended during the
1999-2000 term.
 
    Additionally, outside directors are reimbursed for travel expenses. For
1999-2000 service, the Chair of the Board (who also serves as the Chair of the
Executive Committee) received an annual fee of $15,000. The Chairs of the
respective Board committees each received an annual fee of $7,500. For 2000-2001
service, the Chair of the Board (who also serves as the Chair of the Executive
Committee) will have the option of receiving an annual fee of $15,000 (cash) or
a $15,000 interest in the Company's 2000 Directors Compensation Program (as
described above). Additionally, other Board Committee Chairs will have the
option of receiving an annual fee of $7,500 (cash) or a $7,500 interest in the
2000 Directors Compensation Program. Each Committee Chair must elect the form of
compensation on or before the date of the March Board meeting.

            SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE
 
    The Company believes that, during fiscal year 1999, its officers (as defined
in the rules under Section 16 of the Exchange Act) and directors have complied
with all Section 16(a) filing requirements in a timely manner, except that there
was a a late filing in connection with the purchase of shares by James Anderson.
The Company is not aware of any 10% stockholders.
 
 
                CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS
 
    Certain directors of the Company and Bank and the entities with which they
are affiliated are customers of the Bank and have had banking transactions with
the Bank in the ordinary course of business. The Board of Directors of the Bank
adopted a policy during 1992 to prohibit new loans or the renewal of existing
loans to insiders after December 31, 1993 (other than on an exception basis).
Term loans existing at December 31, 1992 were permitted to remain outstanding
until scheduled maturity. The Company believes that all extensions of credit
included in such transactions were made in compliance with applicable laws and
on substantially the same terms, including interest rates, collateral and
repayment terms, as those prevailing at the time for comparable transactions
with other persons of similar creditworthiness and, in the opinion of the Board
of Directors of the Bank, did not involve more than a normal risk of
collectibility or default or present any other unfavorable features.
 
    In December 1997 and in conjunction with Mr. Wilcox's promotion to Chief
Banking Officer (and corresponding relocation from Massachusetts to California),
the Company agreed to make two interest-free relocation loans to Mr. Wilcox. The
first loan in the amount of $250,000 (funded in December 1997) is payable in
five annual installments, with the final $50,000 installment due on December 1,
2002. The second loan in the amount of $600,000 (funded in January 1998) is due
in full on December 1, 2002. Both loans are secured by a lien on Mr. Wilcox's
principal residence in California. The largest principal amount outstanding
during 1999 was $800,000 and the principal amount outstanding on December 31,
1999 was $750,000.
 
    Also, in conjunction with Mr. Wilcox's promotion and pursuant to a separate
agreement (separate from the above-described loan documents), the Bank has
agreed to pay Mr. Wilcox a guaranteed $50,000 annual bonus for the next five
years (subject to his continued employment by the Bank), with the first such
bonus paid in December 1998 and the final bonus payable in December 2002.
 
    In June 1998 and in conjunction with Mr. Lutes' promotion to Chief Financial
Officer, the Company made a loan in the amount of $75,000 to Mr. Lutes. The loan
accrues interest at the rate of 5.50% per annum and is payable in three equal
annual installments, with the final $25,000 installment due on March 1, 2001.
The loan is unsecured. The largest principal amount outstanding during 1999 was
$75,000 and the principal amount outstanding on December 31, 1999 was $50,000.
 
    In January 1999 and in conjunction with recruiting James Anderson to the
Bank as Executive Vice President and Manager of the Corporate Finance Group, the
Company agreed to make an interest-free loan in the amount of $100,000 to
Mr. Anderson. The loan (funded in January 1999) is payable in five equal annual
installments, with the final $20,000 installment due on March 1, 2004. The loan
is unsecured.

The largest principal amount outstanding during 1999 (and the principal amount
outstanding on December 31, 1999) was $100,000.
 
    In April 1999, the Company made a loan in the amount of $150,000 to
Ms. Kamm to assist her in the payment of taxes. The loan (funded in April 1999)
accrues interest at the rate of 4.75% per annum and is payable in five equal
annual installments, with the final $30,000 installment due on March 1, 2004.
The loan is unsecured. The largest principal amount outstanding during 1999 (and
the principal amount outstanding on December 31, 1999) was $150,000.

APPROVAL OF THE AMENDMENT TO THE SILICON VALLEY BANCSHARES 1997 EQUITY INCENTIVE
                                      PLAN
 
           THE BOARD OF DIRECTORS RECOMMENDS A VOTE "FOR" APPROVAL OF
                THE AMENDMENT TO THE 1997 EQUITY INCENTIVE PLAN
 
INTRODUCTION
 
    The stockholders are being asked to approve an amendment to the 1997 Equity
Incentive Plan (the "Incentive Plan") in order to reserve an additional
1,100,000 shares of Common Stock for issuance thereunder. The Incentive Plan was
adopted by the Board of Directors on December 19, 1996 and approved by the
stockholders on April 17, 1997. The Incentive Plan as adopted had 1,800,000
shares(1) reserved for issuance thereunder.
 
    As of February 22, 2000, 67,121 shares of Common Stock were available for
issuance under the Incentive Plan (exclusive of the increase in shares subject
to stockholder approval at the 2000 Annual Meeting of Stockholders). Options to
purchase 1,347,023 shares were outstanding and since the inception of the
Incentive Plan, 385,856 shares of Common Stock have been issued upon the
exercise of options granted under the Incentive Plan at an average exercise
price per share of $33.769.
 
    The Incentive Plan provides for the grant of incentive stock options to
employees and nonstatutory stock options, stock appreciation rights, restricted
stock purchase awards and stock bonuses (collectively "Stock Awards") to
employees, directors and consultants. Incentive stock options granted under the
Incentive Plan are intended to qualify as "incentive stock options" within the
meaning of Section 422 of the Internal Revenue Code of 1986, as amended (the
"Code"). Nonstatutory stock options granted under the Incentive Plan are not
intended to qualify as incentive stock options under the Code. See "Federal
Income Tax Information" for a discussion of the tax treatment of the various
awards included in the Incentive Plan.
 
VOTE REQUIRED
 
    At the Annual Meeting, stockholders are requested in this Proposal Two to
approve the amendment to the Incentive Plan. The affirmative vote of the Votes
Cast on this proposal will be required to approve the amendment. For purposes of
this vote, abstention and broker non-votes will not be counted for any purpose
in determining whether this matter has been approved. The Board of Directors
r
ecommends a vote "FOR" approval of the amendment to the Incentive Plan.
 
    A summary of the features of the Incentive Plan are outlined below.

                                       25

<PAGE>
SUMMARY OF THE INCENTIVE PLAN
 
PURPOSE
 
    The Incentive Plan provides a means by which selected employees and
directors of, and consultants to, the Company, and its affiliates, may be given
an opportunity to purchase Common Stock of the Company or receive cash based on
stock appreciation. The Company, by means of the Incentive Plan, seeks to retain
the services of persons who are now employees and directors of, or consultants
to, the Company or its affiliates, to secure and retain the services of new
employees, directors and consultants, and to provide incentives for such persons
to exert maximum efforts for the success of the Company and its affiliates.
 
ADMINISTRATION
 
    The Incentive Plan is administered by the Board unless and until the Board
delegates administration to a committee composed of not fewer than two Board
members. All of the members of any such committee must be non-employee directors
(unless the Board expressly declares that such requirement shall not apply) and
may also be, in the discretion of the Board, outside directors. If
administration is delegated to a committee, such committee will have, in
connection with the administration of the Incentive Plan, the powers possessed
by the Board, subject, however, to such resolutions, not inconsistent with the
provisions of the Incentive Plan, as may be adopted from time to time by the
Board.
 
    The Board may abolish such committee at any time and revest in the Board the
administration of the Incentive Plan. The Board has delegated the administration
of the Incentive Plan to the Executive Committee (the "Administrator").
 
    The Administrator has the power to determine from time to time which of the
persons eligible under the Incentive Plan shall be granted awards, the type of
awards to be granted, when and how each award shall be granted, to construe and
interpret the Incentive Plan and awards granted under it, and to establish,
amend and revoke rules and regulations for its administration. The Administrator
may correct any defect in the Incentive Plan or in any award agreement to make
the Incentive Plan fully effective.
 
ELIGIBILITY
 
    Incentive stock options and stock appreciation rights appurtenant thereto
may be granted only to employees. Nonstatutory stock options, restricted stock
purchase awards, stock appreciation rights, and stock bonuses may be granted to
employees, directors or consultants. As of the record date, the Company and Bank
had seven-hundred-thirty (730) employees, and seven (7) non-employee directors
eligible for awards under the plan.
 
    No person is eligible for the grant of an incentive stock option if, at the
time of grant, such person owns stock constituting more than ten percent (10%)
of the total combined voting power of all classes of stock of the Company unless
the exercise price of such option is at least one hundred ten percent (110%) of
the fair market value of such Common Stock subject to the option at the date of
grant and the option is not exercisable after the expiration of five (5) years
from the date of grant, or in the case of a restricted stock purchase award, the
purchase price is at least one hundred percent (100%) of the fair market value
of Common Stock subject to the award at date of grant. In addition, no person
shall be eligible to be granted options and stock appreciation rights covering
more than two hundred fifty thousand (250,000) shares of the Company's Common
Stock in any calendar year.
 
TERM AND TERMINATION OF STOCK OPTIONS
 
    No option is exercisable after the expiration of ten (10) years from the
date it was granted.
 
    In the event an optionee's continuous status as an employee, director or
consultant is terminated, the optionee may exercise his or her option (to the
extent that the optionee was entitled to exercise it at the
 
                                       26

<PAGE>
time of termination) but only within the earlier of (i) the date three
(3) months after the termination of the optionee's continuous status as an
employee, director or consultant, or (ii) the expiration of the term of the
option as set forth in the option agreement.
 
    An optionee's option agreement may also provide that if the exercise of the
option following the termination of the optionee's continuous status as an
employee, director or consultant would result in liability under Section 16(b)
of the Securities Exchange Act of 1934 (the"Exchange Act"), then the option
shall terminate on the earlier of (i) the expiration of the term of the option,
or (ii) the expiration of a period three (3) months after the termination of the
optionee's continuous status as an employee, director or consultant during which
the exercise of the option would not be in violation of such registration
requirements.
 
    In the event an optionee's continuous status as an employee, director or
consultant terminates as a result of the optionee's death or disability, the
optionee (or such optionee's estate, heirs or beneficiaries) may exercise his or
her option, but only within the period ending on the earlier of (i) twelve
(12) months following such termination (or such longer or shorter period as
specified in the option agreement) or (ii) the expiration of the term of the
option as set forth in the option agreement.
 
    In the event a stock bonus or restricted stock recipient's continuous status
as an employee, director or consultant terminates, the Company may repurchase or
otherwise reacquire any or all of the shares of stock held by that person that
have not vested as of the date of termination under the terms of the stock bonus
or restricted stock purchase agreement between the Company and such person.
 
EXERCISE PRICE
 
    The exercise price of each incentive stock option will not be less than one
hundred percent (100%) of the fair market value of the Company's Common Stock on
the date of grant. The exercise price of each nonstatutory stock option will not
be less than eight-five percent (85%) of the fair market value on the date of
grant. The purchase price of restricted stock will not be less than eighty-five
percent (85%) of the fair market value of the Company's Common Stock on the date
such award is made. Stock bonuses may be awarded in consideration for past
services rendered to the Company or for its benefit. The closing price for the
Company's Common Stock on the record date was $64.938 per share, as reported by
National Association of Securities Dealers Automated Quotation/National Market.
 
CONSIDERATION
 
    The purchase price of stock acquired pursuant to a Stock Award is paid
either in cash at the time of exercise or purchase, or (if determined by the
Administrator at the time of grant for an option) by deferred payment or other
arrangement or in any other form of legal consideration that may be acceptable
to the Administrator. Additionally, in the case of an option and in the
discretion of the Administrator at the time of the grant of an option,
consideration may be paid by delivery to the Company of other Common Stock of
the Company. In the case of any deferred payment arrangement, interest will be
payable at least annually and will be charged at the minimum rate of interest
necessary to avoid the treatment as interest of amounts that are not stated to
be interest.
 
TRANSFERABILITY
 
    An incentive stock option shall not be transferable except by will or by the
laws of descent and distribution, and shall be exercisable during the lifetime
of the person to whom the incentive stock option is granted only by such person.
A nonstatutory stock option, stock bonus, or restricted stock award shall only
be transferable upon such terms and conditions as the Administrator shall
determine in its sole discretion at the time of grant. An optionee may designate
a beneficiary who may exercise his or her option after death.

VESTING
 
    The total number of shares of stock subject to an option may, but need not,
be allotted in periodic installments. The option agreement may provide that from
time to time during each of such installment periods, the option may become
exercisable ("vest") with respect to some or all of the shares allotted to that
period. The option agreement may also provide that an optionee may exercise an
option prior to full vesting, provided that the Company has a repurchase right
with respect to any unvested shares.
 
    Restricted stock purchase awards and stock bonuses granted under the
Incentive Plan may be granted subject to a repurchase option in favor of the
Company in accordance with a vesting schedule determined by the Administrator.
 
ADJUSTMENTS UPON CHANGE IN STOCK
 
    If any change is made in the Common Stock, without receipt of consideration
by the Company (through merger, consolidation, reorganization, recapitalization,
stock dividend, dividend in property other than cash, stock split, liquidation
dividend, combination of shares, exchange of shares, change in corporate
structure, or otherwise), the class(es) and maximum number of shares subject to
the Incentive Plan, the maximum annual award applicable under the Incentive Plan
and the class(es) and number of shares and price per share of stock subject to
outstanding Stock Awards will be appropriately adjusted.
 
    In the event of a "Change in Control" (defined below), holders of
outstanding stock options shall have the right to exercise, and shall be vested
as to, all outstanding stock options, including stock options that would not
otherwise be exercisable or vested. If outstanding stock options become fully
vested in the event of a Change in Control, the Administrator shall notify all
participants that their outstanding stock options shall be fully exercisable for
a period of three (3) months (or such other period of time not exceeding six
(6) months as is determined by the Administrator at the time of the grant) from
the date of such notice, and any unexercised options shall terminate upon the
expiration of such period.
 
    In the event of a "Covered Termination" (defined above under "Termination
Arrangements") following a Change in Control, holders of outstanding restricted
stock shares shall be vested as to all shares, including shares which otherwise
were not then vested.
 
    For purposes of the Incentive Plan, "Change in Control" means:
 
        (1) the acquisition of 50% or more of the outstanding voting stock of
    the Company by any person or entity, with certain exceptions for employee
    benefit plans of the Company or the Bank;
 
        (2) the acquisition of 25% or more of the outstanding voting stock of
    the Company by any person or entity and a change in the composition of the
    Board during the following 12 months such that those persons serving as
    directors immediately prior to the share acquisition, and those new
    directors elected by a vote or at least two-thirds of the directors of the
    Company, cease to make up at least 60% of the directors of the Company;
 
        (3) a merger or consolidation of the Company with any other corporation,
    other than a merger or consolidation in which the stockholders of the
    Company immediately prior thereto continue to own more than 50% of the
    outstanding voting stock of the Company; or
 
        (4) the complete liquidation of the Company, or disposition of all or
    substantially all of the Company's assets.
 
AMENDMENT OF THE INCENTIVE PLAN
 
    The Administrator at any time, and from time to time, may amend the
Incentive Plan. However, no amendment shall be effective unless approved by the
stockholders of the Company if stockholder approval is required in order for the
Incentive Plan to satisfy the requirements of Section 422 of the Code, or to
 
                                       28

<PAGE>
comply with the requirements of Rule 16b-3 or the Nasdaq National Market listing
requirements. The Administrator may in its sole discretion submit any other
amendment to the Incentive Plan for stockholder approval.
 
TERMINATION OR SUSPENSION OF THE INCENTIVE PLAN
 
    The Administrator may suspend or terminate the Incentive Plan at any time.
Unless sooner terminated, the Incentive Plan shall terminate on December 18,
2006. No Stock Awards may be granted under the Incentive Plan while the
Incentive Plan is suspended or after it is terminated.
 
FEDERAL INCOME TAX INFORMATION
 
    INCENTIVE STOCK OPTIONS.  Incentive stock options under the Incentive Plan
are intended to be eligible for the favorable federal income tax treatment
accorded "incentive stock options" under the Code.
 
    There generally are no federal income tax consequences to the optionee of
the Company by reason of the grant or exercise of an incentive stock option.
However, the exercise of an incentive stock option may increase the optionee's
alternative minimum tax liability, if any.
 
    If an optionee holds stock acquired through exercise of an incentive stock
option for at least two years from the date on which the option is granted and
at least one year from the date on which the shares are transferred to the
optionee upon exercise of the option, any gain or loss on a disposition of such
stock will be long-term capital gain or loss. Generally, if the optionee
disposes of the stock before the expiration of either of these holding periods
(a "disqualifying disposition"), at the time of disposition, the optionee will
realize taxable ordinary income equal to the lesser of (a) the excess of the
stock's fair market value on the date of exercise over the exercise price, or
(b) the optionee's actual gain, if any, on the purchase and sale. The optionee's
additional gain, or any loss, upon the disqualifying disposition will be a
capital gain or loss, which will be long-term or short-term depending on whether
the stock was held for more than one year. Capital gains currently are generally
subject to lower tax rates than ordinary income. The maximum long-term capital
gains rate for federal income tax purposes is currently 20% while the maximum
federal ordinary income rate is effectively 39.6% at the present time. Slightly
different rules may apply to optionees who acquire stock subject to certain
repurchase options.
 
    To the extent the optionee recognizes ordinary income by reason of a
disqualifying disposition, the Company will generally be entitled (subject to
the requirement of reasonableness and the satisfaction of a tax reporting
obligation) to a corresponding business expense deduction in the tax year in
which the disqualifying disposition occurs.
 
    NONSTATUTORY STOCK OPTIONS.  Nonstatutory stock options granted under the
Incentive Plan generally have the following federal income tax consequences:
 
    There are no tax consequences to the optionee or the Company by reason of
the grant of a nonstatutory stock option. Upon exercise of a nonstatutory stock
option, the optionee normally will recognize taxable ordinary income equal to
the excess of the stock's fair market value on the date of exercise over the
option exercise price. Generally, with respect to employees, the Company is
required to withhold taxes from regular wages or supplemental wage payments an
amount based on the ordinary income recognized. Subject to the requirement of
reasonableness and the satisfaction of a reporting obligation, the Company will
generally be entitled to a business expense deduction equal to the taxable
ordinary income realized by the optionee. Upon disposition of the stock, the
optionee will recognize a capital gain or loss equal to the difference between
the selling price and the purchase price (to the extent not recognized as
taxable income as described above) which will be deemed long or short-term
depending on whether the stock was held for more than one year. Slightly
different rules may apply to optionees who acquire stock subject to certain
repurchase options or who are subject to Section 16(b) of the Exchange Act.
 
                                       29

<PAGE>
    STOCK BONUS AWARDS.  A recipient who receives restricted stock pursuant to a
Stock Bonus Award will recognize ordinary income equal to the fair market value
of the stock at the time or times the restrictions lapse (unless a Code
Section 83(b) election is timely filed at the time of grant). Different rules
may apply if the recipient is subject to Section 16(b) of the Exchange Act.
Generally, the Company will be entitled to a tax deduction in the amount and at
the time the recipient recognizes ordinary income.
 
    PARTICIPATION IN INCENTIVE PLAN
 
    The grant of Stock Awards under the Incentive Plan to employees, including
the executive officers named in the Summary Compensation Table, is subject to
the discretion of the Board. As of the date of this proxy statement, there has
been no determination made by the Administrator with respect to future
discretionary awards to employees or consultants under the Incentive Plan.
Accordingly, future awards to employees and consultants are not determinable.
Non-employee directors also are eligible to participate in the Incentive Plan.
See "Director Compensation" above for a discussion of grants made to directors
to date (subject to the stockholders' approval of the Incentive Plan).
 
    The following table sets forth information with respect to the grant of
options/stock bonuses under the 1997 Equity Incentive Plan during the last
fiscal year to the executive officers named in the Summary Compensation Table,
to all current executive officers as a group and to all other employees as a

                                 PROPOSAL NO. 3
              RATIFICATION OF APPOINTMENT OF INDEPENDENT AUDITORS
 
  THE BOARD OF DIRECTORS RECOMMENDS A VOTE "FOR" THE RATIFICATION OF AUDITORS
 
    The firm of KPMG LLP has been approved by the Audit and Finance Committee
and the Board of Directors of the Company to be the independent auditor of the
Company for the 2000 fiscal year. KPMG LLP has audited the Company's financial
statements since November 1994. The stockholders are being asked to ratify the
selection of KPMG LLP. If the stockholders do not ratify such selection by the
affirmative vote of a majority of the Votes Cast, the Board will reconsider its
selection.
 
    Representatives from the firm of KPMG LLP will be present at the Annual
Meeting of Stockholders and afforded the opportunity to make a statement if they
desire to do so, and will be available to respond to stockholders' questions.
 
                             STOCKHOLDER PROPOSALS
 
    Stockholders are entitled to present proposals for action at a forthcoming
Annual Meeting of Stockholders only if they comply with the applicable
requirements of corporate law, the proxy rules and the Company's Bylaws. Any
stockholder proposal intended to be presented at the 2001 Annual Meeting of
Stockholders of the Company that a stockholder desires to have included in the
Company's Proxy Statement relating to such meeting must be received at the
Company's principal executive office on or before November 16, 2000 in order to
be considered for possible inclusion in the Company's Proxy Statement and form
of proxy relating to such annual meeting.
 
    Under the Company's bylaws, in order for a stockholder proposal to be deemed
properly presented, notice must be delivered to the Secretary of the Company,
not less than 60 days nor more than 90 days prior to the Annual Meeting;
provided, however, if less than 65 days' notice of the date of the Annual
Meeting has been given, notice by the stockholder to be timely must be received
by the Company no later than the close of business on the seventh (7th) day
following the day on which such notice of the Annual Meeting was mailed. The
deadline computed in accordance with the foregoing is referred to as the "Bylaw
Deadline." The stockholder's notice must set forth, as to each proposed matter:
(a) a brief description of the business and reason for conducting such business
at the meeting; (b) the name and address as they appear on the Company's books
of the stockholder proposing such business, or the name of the beneficial holder
or other party on whose behalf the proposal is made; (c) the class and number of
shares of the Company owned by the stockholder or beneficial holder or other
party on whose behalf the proposal is made; and (d) any material interest of the
stockholder or beneficial holder or other party on whose behalf the proposal is
made in such business. The presiding officer of the meeting may refuse to
acknowledge any matter not made in compliance with the foregoing procedure.
 
    If stockholder wishes to present a proposal at the Company's annual meeting
in the year 2000 and the proposal is not intended to be included in the
Company's proxy statement relating to that meeting, the stockholder must give
advance notice to the Company prior to the Bylaw Deadline for such meeting
determined in accordance with the Bylaws, as described above. If a stockholder
gives notice of such a proposal after the Bylaw Deadline, the stockholder will
not be permitted to present the proposal to the stockholders for a vote at the
meeting.
 
    SEC rules also establish a different deadline for submission of stockholder
proposals that are not intended to be included in the Company's proxy statement
with respect to discretionary voting (the "Discretionary Vote Deadline"). The
Discretionary Vote Deadline for the year 2001 annual meeting is January 31, 2001
(45 calendar days prior to the anniversary of the mailing date of this proxy
statement). If a stockholder gives notice of such a proposal after the
Discretionary Vote Deadline, the Company's proxy holders will be allowed to use
their discretionary voting authority to vote against the stockholder proposal
when and if the proposal is raised at the Company's year 2001 annual meeting.
Because the Bylaw
 
                                       31

<PAGE>
Deadline is not capable of being determined until the Company publicly announces
the date for its next annual meeting, it is possible that the Bylaw Deadline may
occur after the Discretionary Vote Deadline. In such a case, a proposal received
after the Discretionary Vote Deadline but before the Bylaw Deadline would be
eligible to be presented at next year's annual meeting and the Company believes
that its proxy holders would be allowed to use the discretionary authority
granted by the proxy card to vote against the proposal at the meeting without
including any disclosure of the proposal in the proxy statement relating to such
meeting.
 
    The Company has not been notified by any stockholder of his or her intent to
present a stockholder proposal from the floor at this year's Annual Meeting. The
enclosed proxy card grants the proxy holders discretionary authority to vote on
any matter properly brought before the Annual Meeting, including any stockholder
proposals received between the date of this proxy statement and the Bylaw
Deadline for this year's Annual Meeting, which is March 24, 2000.
 
                               1999 ANNUAL REPORT
 
    Enclosed is a copy of the Company's 1999 Annual Report to Stockholders,
including financial statements for the year ended December 31, 1999. Also
enclosed is a copy of the Company's Annual Report on Form 10-K (without
exhibits) for the year ended December 31, 1999 as filed with the Securities and
Exchange Commission. Stockholders who wish to obtain additional copies of the
Annual Report to Stockholders or the Annual Report on Form 10-K should address a

                                OTHER MATTERS
 
    As of the date of this Proxy Statement, there are no other matters that
Management intends to present or has reason to believe others will present at
the Annual Meeting. If other matters properly come before the Annual Meeting,
those who act as Proxy Holders will vote in accordance with their best judgment.

    (B) The Board shall have the power, subject to, and within the limitations
of, the express provisions of the Plan:
 
        (1) To determine from time to time which of the persons eligible under
    the Plan shall be granted Stock Awards; when and how each Stock Award shall
    be granted; whether a Stock Award will be an Incentive Stock Option, a
    Nonstatutory Stock Option, a stock bonus, a right to purchase restricted

    administration. The Board, in the exercise of this power, may correct any
    defect, omission or inconsistency in the Plan or in any Stock Award

    expedient to make the Plan fully effective.

of the Plan, the powers theretofore possessed by the Board, (and references in
this Plan to the Board shall thereafter be to the Committee), subject, however,
to such resolutions, not inconsistent with the provisions of the Plan, as may be
adopted from time to time by the Board. The Board may abolish the Committee at
any time and revest in the Board the administration of the Plan.
 
4.  SHARES SUBJECT TO THE PLAN.
 
    (A) Subject to the provisions of Section 13 relating to adjustments upon
changes in stock, the stock that may be issued pursuant to Stock Awards shall
not exceed in the aggregate nine hundred thousand (900,000) shares of the
Company's common stock. If any Stock Award shall for any reason expire or
otherwise terminate, in whole or in part, without having been exercised in full,
the stock not acquired under such Stock Award shall revert to and again become
available for issuance under the Plan. Shares subject to Stock Appreciation
Rights exercised in accordance with Section 8 of the Plan shall not be available
for subsequent issuance under the Plan.
 
    (B) The stock subject to the Plan may be unissued shares or reacquired
shares, bought on the market or otherwise.
 
5.  ELIGIBILITY.
 
    (A) Incentive Stock Options and Stock Appreciation Rights appurtenant
thereto may be granted only to Employees. Stock Awards other than Incentive
Stock Options and Stock Appreciation Rights appurtenant thereto may be granted
only to Employees, Directors or Consultants.
 
    (B) No person shall be eligible for the grant of an Incentive Stock Option
if, at the time of grant, such person owns (or is deemed to own pursuant to
Section 424(d) of the Code) stock possessing more than ten percent (10%) of the
total combined voting power of all classes of stock of the Company or of any of
its Affiliates unless the exercise price of such Option is at least one hundred
ten percent (110%) of the Fair Market Value of such stock at the date of grant
and the Option is not exercisable after the expiration of five (5) years from
the date of grant.
 
    (C) Subject to the provisions of Section 13 relating to adjustments upon
changes in stock, no person shall be eligible to be granted Options and Stock
Appreciation Rights covering more than two hundred fifty thousand (250,000)
shares of the Company's common stock in any calendar year.
 
6.  OPTION PROVISIONS.
 
    Each Option shall be in such form and shall contain such terms and
conditions as the Board shall deem appropriate. The provisions of separate
Options need not be identical, but each Option shall include (through
incorporation of provisions hereof by reference in the Option or otherwise) the
substance of each of the following provisions:
 
    (A) TERM.  No Option shall be exercisable after the expiration of ten
(10) years from the date it was granted.
 
    (B) PRICE.  The exercise price of each Incentive Stock Option shall be not
less than one hundred percent (100%) of the Fair Market Value of the stock
subject to the Option on the date the Option is granted; the exercise price of
each Nonstatutory Stock Option shall be not less than eighty-five percent (85%)
the Fair Market Value of the stock subject to the Option on the date the Option
is granted. Notwithstanding the foregoing, an Option (whether an Incentive Stock
Option or a Nonstatutory Stock Option) may be granted with an exercise price
lower than that set forth in the preceding sentence if such
 
                                      A-4

<PAGE>
Option is granted pursuant to an assumption or substitution for another option
in a manner satisfying the provisions of Section 424(a) of the Code.
 
    (C) CONSIDERATION.  The purchase price of stock acquired pursuant to an
Option shall be paid, to the extent permitted by applicable statutes and
regulations, either (i) in cash at the time the Option is exercised, or (ii) at
the discretion of the Board or the Committee, at the time of the grant of the
Option, (A) by delivery to the Company of other common stock of the Company,
(B) according to a deferred payment or other arrangement (which may include,
without limiting the generality of the foregoing, the use of other common stock
of the Company) with the person to whom the Option is granted or to whom the
Option is transferred pursuant to subsection 6(d), or (C) in any other form of
legal consideration acceptable to the Board. In the case of any deferred payment
arrangement, interest shall be compounded at least annually and shall be charged
at the minimum rate of interest necessary to avoid the treatment as interest,
under any applicable provisions of the Code, of any amounts other than amounts
stated to be interest under the deferred payment arrangement.
 
    (D) TRANSFERABILITY.  An Incentive Stock Option shall not be transferable
except by will or by the laws of descent and distribution, and shall be
exercisable during the lifetime of the person to whom the Incentive Stock Option
is granted only by such person. A Nonstatutory Stock Option shall only be
transferable by the Optionee upon such terms and conditions as are set forth in
the Option Agreement for such Nonstatutory Stock Option, as the Board or the
Committee shall determine in its sole discretion. The person to whom the Option
is granted may, by delivering written notice to the Company, in a form
satisfactory to the Company, designate a third party who, in the event of the
death of the Optionee, shall thereafter be entitled to exercise the Option.
 
    (E) VESTING.  The total number of shares of stock subject to an Option may,
but need not, be allotted in periodic installments (which may, but need not, be
equal). The Option Agreement may provide that from time to time during each of
such installment periods, the Option may become exercisable ("vest") with
respect to some or all of the shares allotted to that period, and may be
exercised with respect to some or all of the shares allotted to such period
and/or any prior period as to which the Option became vested but was not fully
exercised. The Option may be subject to such other terms and conditions on the
time or times when it may be exercised (which may be based on performance or
other criteria) as the Board may deem appropriate. The provisions of this
subsection 6(e) are subject to any Option provisions governing the minimum
number of shares as to which an Option may be exercised.
 
    (F) TERMINATION OF EMPLOYMENT OR RELATIONSHIP AS A DIRECTOR OR
CONSULTANT.  In the event an Optionee's Continuous Status as an Employee,
Director or Consultant terminates (other than upon the Optionee's death or
disability or for Cause), the Optionee may exercise his or her Option (to the
extent that the Optionee was entitled to exercise it as of the date of
termination) but only within such period of time ending on the earlier of
(i) the date three (3) months following the termination of the Optionee's
Continuous Status as an Employee, Director or Consultant (or such longer or
shorter period specified in the Option Agreement), or (ii) the expiration of the
term of the Option as set forth in the Option Agreement. If, at the date of
termination, the Optionee is not entitled to exercise his or her entire Option,
the shares covered by the unexercisable portion of the Option shall revert to
and again become available for issuance under the Plan. If, after termination,
the Optionee does not exercise his or her Option within the time specified in
the Option Agreement, the Option shall terminate, and the shares covered by such
Option shall revert to and again become available for issuance under the Plan.
 
    In the event an Optionee's Continuous Status as an Employee, Director or
Consultant terminates for Cause, then the Option shall immediately terminate,
and the shares covered by such Option shall revert to and again become available
for issuance under the Plan. "Cause" shall be defined as an act of embezzlement,
fraud, dishonesty, or breach of fiduciary duty to the Company, a deliberate
disregard of the rules of the Company which results in loss, damage or injury to
the Company, any unauthorized disclosure of any of the secrets or confidential
information of the Company, inducing any client or customer of the
 
                                      A-5

<PAGE>
Company to break any contract with the Company or inducing any principal for
whom the Company acts as agent to terminate such agency relations, or engaging
in any conduct which constitutes unfair competition with the Company, or any act
which results in Optionee being removed from any office of the Company by any
bank regulatory agency.
 
    An Optionee's Option Agreement may also provide that if the exercise of the
Option following the termination of the Optionee's Continuous Status as an
Employee, Director, or Consultant (other than upon the Optionee's death or
disability) would result in liability under Section 16(b) of the Exchange Act,
then the Option shall terminate on the earlier of (i) the expiration of the term
of the Option set forth in the Option Agreement, or (ii) the tenth (10th) day
after the last date on which such exercise would result in such liability under
Section 16(b) of the Exchange Act. Finally, an Optionee's Option Agreement may
also provide that if the exercise of the Option following the termination of the
Optionee's Continuous Status as an Employee, Director or Consultant (other than
upon the Optionee's death or disability) would be prohibited at any time solely
because the issuance of shares would violate the registration requirements under
the Securities Act, then the Option shall terminate on the earlier of (i) the
expiration of the term of the Option, or (ii) the expiration of a period of
three (3) months after the termination of the Optionee's Continuous Status as an
Employee, Director or Consultant during which the exercise of the Option would
not be in violation of such registration requirements.
 
    (G) DISABILITY OF OPTIONEE.  In the event an Optionee's Continuous Status as
an Employee, Director or Consultant terminates as a result of the Optionee's
disability, the Optionee may exercise his or her Option (to the extent that the
Optionee was entitled to exercise it as of the date of termination), but only
within such period of time ending on the earlier of (i) the date twelve
(12) months following such termination (or such longer or shorter period
specified in the Option Agreement), or (ii) the expiration of the term of the
Option as set forth in the Option Agreement. If, at the date of termination, the
Optionee is not entitled to exercise his or her entire Option, the shares
covered by the unexercisable portion of the Option shall revert to and again
become available for issuance under the Plan. If, after termination, the
Optionee does not exercise his or her Option within the time specified herein,
the Option shall terminate, and the shares covered by such Option shall revert
to and again become available for issuance under the Plan.
 
    (H) DEATH OF OPTIONEE.  In the event an Optionee's Continuous Status as an
Employee, Director or Consultant terminates as a result of Optionee's death, the
Option may be exercised (to the extent the Optionee was entitled to exercise the
Option as of the date of death) by the Optionee's estate, by a person who
acquired the right to exercise the Option by bequest or inheritance or by a
person designated to exercise the option upon the Optionee's death pursuant to
subsection 6(d), but only within the period ending on the earlier of (i) the
date twelve (12) months following the date of death (or such longer or shorter
period specified in the Option Agreement), or (ii) the expiration of the term of
such Option as set forth in the Option Agreement. If, at the time of death, the
Optionee was not entitled to exercise his or her entire Option, the shares
covered by the unexercisable portion of the Option shall revert to and again
become available for issuance under the Plan. If, after death, the Option is not
exercised within the time specified herein, the Option shall terminate, and the
shares covered by such Option shall revert to and again become available for
issuance under the Plan.
 
    (I) EARLY EXERCISE.  The Option may, but need not, include a provision
whereby the Optionee may elect at any time while an Employee, Director or
Consultant to exercise the Option as to any part or all of the shares subject to
the Option prior to the full vesting of the Option. Any unvested shares so
purchased may be subject to a repurchase right in favor of the Company or to any
other restriction the Board determines to be appropriate.
 
                                      A-6

<PAGE>
7.  TERMS OF STOCK BONUSES AND PURCHASES OF RESTRICTED STOCK.
 
    Each stock bonus or restricted stock purchase agreement shall be in such
form and shall contain such terms and conditions as the Board or the Committee
shall deem appropriate. The terms and conditions of stock bonus or restricted
stock purchase agreements may change from time to time, and the terms and
conditions of separate agreements need not be identical, but each stock bonus or
restricted stock purchase agreement shall include (through incorporation of
provisions hereof by reference in the agreement or otherwise) the substance of
each of the following provisions as appropriate:
 
    (A) PURCHASE PRICE.  The purchase price under each restricted stock purchase
agreement shall be such amount as the Board or Committee shall determine and
designate in such Stock Award Agreement, but in no event shall the purchase
price be less than eighty-five percent (85%) of the stock's Fair Market Value on
the date such award is made. Notwithstanding the foregoing, the Board or the
Committee may determine that eligible participants in the Plan may be awarded
stock pursuant to a stock bonus agreement in consideration for past services
actually rendered to the Company or for its benefit.
 
    (B) TRANSFERABILITY.  Rights under a stock bonus or restricted stock
purchase agreement shall be transferable by the grantee only upon such terms and
conditions as are set forth in the applicable Stock Award Agreement, as the
Board or the Committee shall determine in its discretion, so long as stock
awarded under such Stock Award Agreement remains subject to the terms of the
agreement.
 
    (C) CONSIDERATION.  The purchase price of stock acquired pursuant to a stock
purchase agreement shall be paid either: (i) in cash at the time of purchase;
(ii) at the discretion of the Board or the Committee, according to a deferred
payment or other arrangement with the person to whom the stock is sold; or
(iii) in any other form of legal consideration that may be acceptable to the
Board or the Committee in its discretion. Notwithstanding the foregoing, the
Board or the Committee to which administration of the Plan has been delegated
may award stock pursuant to a stock bonus agreement in consideration for past
services actually rendered to the Company or for its benefit.
 
    (D) VESTING.  Shares of stock sold or awarded under the Plan may, but need
not, be subject to a repurchase option in favor of the Company in accordance
with a vesting schedule to be determined by the Board or the Committee.
 
    (E) TERMINATION OF EMPLOYMENT OR RELATIONSHIP AS A DIRECTOR OR
CONSULTANT.  In the event a Participant's Continuous Status as an Employee,
Director or Consultant terminates, the Company may repurchase or otherwise
reacquire any or all of the shares of stock held by that person which have not
vested as of the date of termination under the terms of the stock bonus or
restricted stock purchase agreement between the Company and such person.
 
8.  STOCK APPRECIATION RIGHTS.
 
    (A) The Board or Committee shall have full power and authority, exercisable
in its sole discretion, to grant Stock Appreciation Rights under the Plan to
Employees or Directors of or Consultants to, the Company or its Affiliates. To
exercise any outstanding Stock Appreciation Right, the holder must provide
written notice of exercise to the Company in compliance with the provisions of
the Stock Award Agreement evidencing such right. Except as provided in
subsection 5(c), no limitation shall exist on the aggregate amount of cash
payments the Company may make under the Plan in connection with the exercise of
a Stock Appreciation Right.
 
    (B) Three types of Stock Appreciation Rights shall be authorized for
issuance under the Plan:
 
        (1) TANDEM STOCK APPRECIATION RIGHTS.  Tandem Stock Appreciation Rights
    will be granted appurtenant to an Option, and shall, except as specifically
    set forth in this Section 8, be subject to the same terms and conditions
    applicable to the particular Option grant to which it pertains. Tandem Stock
    Appreciation Rights will require the holder to elect between the exercise of
    the underlying
 
                                      A-7

<PAGE>
    Option for shares of stock and the surrender, in whole or in part, of such
    Option for an appreciation distribution. The appreciation distribution
    payable on the exercised Tandem Right shall be in cash (or, if so provided,
    in an equivalent number of shares of stock based on Fair Market Value on the
    date of the Option surrender) in an amount up to the excess of (A) the Fair
    Market Value (on the date of the Option surrender) of the number of shares
    of stock covered by that portion of the surrendered Option in which the
    Optionee is vested over (B) the aggregate exercise price payable for such
    vested shares.
 
        (2) CONCURRENT STOCK APPRECIATION RIGHTS.  Concurrent Rights will be
    granted appurtenant to an Option and may apply to all or any portion of the
    shares of stock subject to the underlying Option and shall, except as
    specifically set forth in this Section 8, be subject to the same terms and
    conditions applicable to the particular Option grant to which it pertains. A
    Concurrent Right shall be exercised automatically at the same time the
    underlying Option is exercised with respect to the particular shares of
    stock to which the Concurrent Right pertains. The appreciation distribution
    payable on an exercised Concurrent Right shall be in cash (or, if so
    provided, in an equivalent number of shares of stock based on Fair Market
    Value on the date of the exercise of the Concurrent Right) in an amount
    equal to such portion as shall be determined by the Board or the Committee
    at the time of the grant of the excess of (A) the aggregate Fair Market
    Value (on the date of the exercise of the Concurrent Right) of the vested
    shares of stock purchased under the underlying Option which have Concurrent
    Rights appurtenant to them over (B) the aggregate exercise price paid for
    such shares.
 
        (3) INDEPENDENT STOCK APPRECIATION RIGHTS.  Independent Rights will be
    granted independently of any Option and shall, except as specifically set
    forth in this Section 8, be subject to the same terms and conditions
    applicable to Nonstatutory Stock Options as set forth in Section 6. They
    shall be denominated in share equivalents. The appreciation distribution
    payable on the exercised Independent Right shall be not greater than an
    amount equal to the excess of (A) the aggregate Fair Market Value (on the
    date of the exercise of the Independent Right) of a number of shares of
    Company stock equal to the number of share equivalents in which the holder
    is vested under such Independent Right, and with respect to which the holder
    is exercising the Independent Right on such date, over (B) the aggregate
    Fair Market Value (on the date of the grant of the Independent Right) of
    such number of shares of Company stock. The appreciation distribution
    payable on the exercised Independent Right shall be in cash or, if so
    provided, in an equivalent number of shares of stock based on Fair Market
    Value on the date of the exercise of the Independent Right.
 
9.  CANCELLATION AND RE-GRANT OF OPTIONS.
 
    (A) The Board or the Committee shall have the authority to effect, at any
time and from time to time, (i) the repricing of any outstanding Options and/or
any Stock Appreciation Rights under the Plan and/or (ii) with the consent of the
affected holders of Options and/or Stock Appreciation Rights, the cancellation
of any outstanding Options and/or any Stock Appreciation Rights under the Plan
and the grant in substitution therefor of new Options and/or Stock Appreciation
Rights under the Plan covering the same or different numbers of shares of stock,
but having an exercise price per share not less than eighty-five percent (85%)
of the Fair Market Value (one hundred percent (100%) of the Fair Market Value in
the case of an Incentive Stock Option) or, in the case of a 10% shareholder (as
described in subsection 5(b)) receiving a new grant of an Incentive Stock
Option, not less than one hundred ten percent (110%) of the Fair Market Value)
per share of stock on the new grant date. Notwithstanding the foregoing, the
Board or the Committee may grant an Option and/or Stock Appreciation Right with
an exercise price lower than that set forth above if such Option and/or Stock
Appreciation Right is granted as part of a transaction to which section 424(a)
of the Code applies.
 
    (B) Shares subject to an Option or Stock Appreciation Right canceled under
this Section 9 shall continue to be counted against the maximum award of Options
and Stock Appreciation Rights permitted to be granted pursuant to subsection
5(c) of the Plan. The repricing of an Option and/or Stock Appreciation Right
under this Section 9, resulting in a reduction of the exercise price, shall be
deemed to
 
                                      A-8

<PAGE>
be a cancellation of the original Option and/or Stock Appreciation Right and the
grant of a substitute Option and/or Stock Appreciation Right; in the event of
such repricing, both the original and the substituted Options and Stock
Appreciation Rights shall be counted against the maximum awards of Options and
Stock Appreciation Rights permitted to be granted pursuant to subsection 5(c) of
the Plan. The provisions of this subsection 9(b) shall be applicable only to the
extent required by Section 162(m) of the Code.
 
10.  COVENANTS OF THE COMPANY.
 
    (A) During the terms of the Stock Awards, the Company shall keep available
at all times the number of shares of stock required to satisfy such Stock
Awards.
 
    (B) The Company shall seek to obtain from each regulatory commission or
agency having jurisdiction over the Plan such authority as may be required to
issue and sell shares of stock upon exercise of the Stock Award; provided,
however, that this undertaking shall not require the Company to register under
the Securities Act either the Plan, any Stock Award or any stock issued or
issuable pursuant to any such Stock Award. If, after reasonable efforts, the
Company is unable to obtain from any such regulatory commission or agency the
authority which counsel for the Company deems necessary for the lawful issuance
and sale of stock under the Plan, the Company shall be relieved from any
liability for failure to issue and sell stock upon exercise of such Stock Awards
unless and until such authority is obtained.
 
11.  USE OF PROCEEDS FROM STOCK.
 
    Proceeds from the sale of stock pursuant to Stock Awards shall constitute
general funds of the Company.
 
12.  MISCELLANEOUS.
 
    (A) The Board shall have the power to accelerate the time at which a Stock
Award may first be exercised or the time during which a Stock Award or any part
thereof will vest pursuant to subsection 6(e), 7(d) or 8(b), notwithstanding the
provisions in the Stock Award stating the time at which it may first be
exercised or the time during which it will vest.
 
    (B) Neither an Employee, Director or Consultant nor any person to whom a
Stock Award is transferred under subsection 6(d), 7(b), or 8(b) shall be deemed
to be the holder of, or to have any of the rights of a holder with respect to,
any shares subject to such Stock Award unless and until such person has
satisfied all requirements for exercise of the Stock Award pursuant to its
terms.
 
    (C) Nothing in the Plan or any instrument executed or Stock Award granted
pursuant thereto shall confer upon any Employee, Director, Consultant or other
holder of Stock Awards any right to continue in the employ of the Company or any
Affiliate (or to continue acting as a Director or Consultant) or shall affect
the right of the Company or any Affiliate to terminate the employment of any
Employee with or without cause the right of the Company's Board of Directors
and/or the Company's shareholders to remove any Director as provided in the
Company's Bylaws and the provisions of the California Corporations Code, or the
right to terminate the relationship of any Consultant subject to the terms of
such Consultant's agreement with the Company or Affiliate.
 
    (D) To the extent that the aggregate Fair Market Value (determined at the
time of grant) of stock with respect to which Incentive Stock Options are
exercisable for the first time by any Optionee during any calendar year under
all plans of the Company and its Affiliates exceeds one hundred thousand dollars
($100,000), the Options or portions thereof which exceed such limit (according
to the order in which they were granted) shall be treated as Nonstatutory Stock
Options.
 
    (E) The Company may require any person to whom a Stock Award is granted, or
any person to whom a Stock Award is transferred pursuant to subsection 6(d),
7(b) or 8(b), as a condition of exercising or
 
                                      A-9

<PAGE>
acquiring stock under any Stock Award, (1) to give written assurances
satisfactory to the Company as to such person's knowledge and experience in
financial and business matters and/or to employ a purchaser representative
reasonably satisfactory to the Company who is knowledgeable and experienced in
financial and business matters, and that he or she is capable of evaluating,
alone or together with the purchaser representative, the merits and risks of
exercising the Stock Award; and (2) to give written assurances satisfactory to
the Company stating that such person is acquiring the stock subject to the Stock
Award for such person's own account and not with any present intention of
selling or otherwise distributing the stock. The foregoing requirements, and any
assurances given pursuant to such requirements, shall be inoperative if (i) the
issuance of the shares upon the exercise or acquisition of stock under the Stock
Award has been registered under a then currently effective registration
statement under the Securities Act, or (ii) as to any particular requirement, a
determination is made by counsel for the Company that such requirement need not
be met in the circumstances under the then applicable securities laws. The
Company may, upon advice of counsel to the Company, place legends on stock
certificates issued under the Plan as such counsel deems necessary or
appropriate in order to comply with applicable securities laws, including, but
not limited to, legends restricting the transfer of the stock.
 
    (F) To the extent provided by the terms of a Stock Award Agreement, the
person to whom a Stock Award is granted may satisfy any federal, state or local
tax withholding obligation relating to the exercise or acquisition of stock
under a Stock Award by any of the following means or by a combination of such
means: (1) tendering a cash payment; (2) authorizing the Company to withhold
shares from the shares of the common stock otherwise issuable to the participant
as a result of the exercise or acquisition of stock under the Stock Award; or
(3) delivering to the Company owned and unencumbered shares of the common stock
of the Company.
 
13.  ADJUSTMENTS UPON CHANGES IN STOCK.
 
    (A) If any change is made in the stock subject to the Plan, or subject to
any Stock Award (through merger, consolidation, reorganization,
recapitalization, reincorporation, stock dividend, dividend in property other
than cash, stock split, liquidating dividend, combination of shares, exchange of
shares, change in corporate structure or other transaction not involving the
receipt of consideration by the Company), the Plan will be appropriately
adjusted in the type(s) and maximum number of securities subject to the Plan
pursuant to subsection 4(a) and the maximum number of securities subject to
award to any person during any calendar year pursuant to subsection 5(c), and
the outstanding Stock Awards will be appropriately adjusted in the type(s) and
number of securities and price per share of stock subject to such outstanding
Stock Awards. Such adjustments shall be made by the Board or the Committee, the
determination of which shall be final, binding and conclusive. (The conversion
of any convertible securities of the Company shall not be treated as a

    Securities") of the Company outstanding immediately prior thereto continuing
    to beneficially own securities representing (either by remaining outstanding
    or by being converted into voting securities of the surviving entity) more

    Rule 13d-3 under the Exchange Act), directly or indirectly, of the
    securities of the Company representing fifty percent (50%) or more of the
    Voting Securities; or
 
        (4) (A)  (1) the shareholders of the Company approve a merger or
    consolidation of the Company with any other corporation, other than a merger
    or consolidation which would result in beneficial owners of Voting
    Securities of the Company outstanding immediately prior thereto continuing

    or by being converted into voting securities of the surviving entity) more
    than twenty-five percent (25%) of the total Voting Securities of the

    (A) The Board at any time, and from time to time, may amend the Plan and/or
some or all outstanding Stock Awards granted under the Plan. However, except as
provided in paragraph 13 relating to adjustments upon changes in stock, no
amendment shall be effective unless approved by the shareholders of the Company
to the extent shareholder approval is necessary for the Plan to satisfy the
requirements of Section 422 of the Code, Rule 16b-3 or any Nasdaq or securities
exchange listing requirements.
 
    (B) The Board may in its sole discretion submit any other amendment to the
Plan for shareholder approval, including, but not limited to, amendments to the
Plan intended to satisfy the requirements of Section 162(m) of the Code and the
regulations promulgated thereunder regarding the exclusion of performance-based
compensation from the limit on corporate deductibility of compensation paid to
certain executive officers.
 
    (C) It is expressly contemplated that the Board may amend the Plan in any
respect the Board deems necessary or advisable to provide eligible Employees

Code and the regulations promulgated thereunder relating to Incentive Stock
Options and/or to bring the Plan and/or Incentive Stock Options granted under it
into compliance therewith.
 
    (D) Rights and obligations under any Stock Award granted before amendment of

Company requests the consent of the person to whom the Stock Award was granted
and (ii) such person consents in writing.
 
    (E) The Board at any time, and from time to time, may amend the terms of any
one or more Stock Award; provided, however, that the rights and obligations
under any Stock Award shall not be impaired by any such amendment unless
(i) the Company requests the consent of the person to whom the Stock Award was
granted and (ii) such person consents in writing.
 
15.  TERMINATION OR SUSPENSION OF THE PLAN.
 
    (A) The Board may suspend or terminate the Plan at any time. Unless sooner
terminated, the Plan shall terminate on December 18, 2006 which shall be within
ten (10) years from the date the Plan is adopted by the Board or approved by the
shareholders of the Company, whichever is earlier. No Stock Awards may be
granted under the Plan while the Plan is suspended or after it is terminated.
 
    (B) Rights and obligations under any Stock Award granted while the Plan is
in effect shall not be impaired by suspension or termination of the Plan, except
with the written consent of the person to whom the Stock Award was granted.
 
16.  EFFECTIVE DATE OF PLAN.
 
    The Plan shall become effective as determined by the Board, but no Stock
Awards granted under the Plan shall be exercised unless and until the Plan has
been approved by the shareholders of the Company, which approval shall be within
twelve (12) months before or after the date the Plan is adopted by the Board,
and, if required, an appropriate permit has been issued by the Commissioner of
Corporations of the State of California.
