                            SILICON VALLEY BANCSHARES

                        1999 EMPLOYEE STOCK PURCHASE PLAN

              ADOPTED BY THE BOARD OF DIRECTORS ON JANUARY 21, 1999
                 APPROVED BY THE STOCKHOLDERS ON APRIL 15, 1999
                          EFFECTIVE DATE APRIL 15, 1999

1.       PURPOSE.

         (a) The purpose of this 1999 Employee Stock Purchase Plan (the "Plan")
is to provide a means by which employees of Silicon Valley Bancshares, a
California corporation (the "Company"), and its Affiliates, as defined in
subparagraph 1(b), which are designated as provided in subparagraph 2(b), may be
given an opportunity to purchase stock of the Company. This 1999 Employee Stock
Purchase Plan is intended to replace the Silicon Valley Bancshares 1988 Employee
Stock Purchase Plan.

         (b) The word "Affiliate" as used in the Plan means any parent
corporation or subsidiary corporation of the Company, as those terms are defined
in Sections 424(e) and (f), respectively, of the Internal Revenue Code of 1986,
as amended (the "Code").

         (c) The Company, by means of the Plan, seeks to retain the services of
its employees, to secure and retain the services of new employees, and to
provide incentives for such persons to exert maximum efforts for the success of
the Company.

         (d) The Company intends that the rights to purchase stock of the
Company granted under the Plan be considered options issued under an "employee
stock purchase plan" as that term is defined in Section 423(b) of the Code.

2.       ADMINISTRATION.

         (a) The Plan shall be administered by the Board of Directors (the
"Board") of the Company unless and until the Board delegates administration to a
Committee, as provided in subparagraph 2(c). Whether or not the Board has
delegated administration, the Board shall have the final power to determine all
questions of policy and expediency that may arise in the administration of the
Plan.

         (b) The Board shall have the power, subject to, and within the
limitations of, the express provisions of the Plan:

               (i) To determine when and how rights to purchase stock of the
Company shall be granted and the provisions of each offering of such rights
(which need not be identical).

              (ii) To designate from time to time which Affiliates of the
Company shall be eligible to participate in the Plan.

<PAGE>

             (iii) To construe and interpret the Plan and rights granted under
it, and to establish, amend and revoke rules and regulations for its
administration. The Board, in the exercise of this power, may correct any
defect, omission or inconsistency in the Plan, in a manner and to the extent it
shall deem necessary or expedient to make the Plan fully effective.

              (iv) To amend the Plan as provided in paragraph 13.

               (v) Generally, to exercise such powers and to perform such acts
as the Board deems necessary or expedient to promote the best interests of the
Company and its Affiliates and to carry out the intent that the Plan be treated
as an "employee stock purchase plan" within the meaning of Section 423 of the
Code.

          (c) The Board may delegate administration of the Plan to a Committee
composed of one (1) or more members of the Board (the "Committee"). If
administration is delegated to a Committee, the Committee shall have, in
connection with the administration of the Plan, the powers theretofore possessed
by the Board, 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.

          (d) Any interpretation of the Plan by the Board of any decision made
by it under the Plan shall be final and binding on all persons.

3.       SHARES SUBJECT TO THE PLAN.

         (a) Subject to the provisions of paragraph 12 relating to adjustments
upon changes in stock, the stock that may be sold pursuant to rights granted
under the Plan shall not exceed in the aggregate one million (1,000,000) shares
of the Company's common stock (the "Common Stock. If any right granted under the
Plan shall for any reason terminate without having been exercised, the Common
Stock not purchased under such right shall again become available for the Plan.

         (b) The stock subject to the Plan may be unissued shares or reacquired
shares, bought on the market or otherwise.

4.       GRANT OF RIGHTS; OFFERING.

         (a) The Board or the Committee may from time to time grant or provide
for the grant of rights to purchase Common Stock of the Company under the Plan
to eligible employees (an "Offering") on a date or dates (the "Offering
Date(s)") selected by the Board or the Committee. Each Offering shall be in such
form and shall contain such terms and conditions as the Board or the Committee
shall deem appropriate, which shall comply with the requirements of Section
423(b)(5) of the Code that all employees granted rights to purchase stock under
the Plan shall have the same rights and privileges. The terms and conditions of
an Offering shall be incorporated by reference into the Plan and treated as part
of the Plan. The provisions of separate Offerings need not be identical, but
each Offering shall include (through incorporation of the provisions of this
Plan by reference in the document comprising the Offering or otherwise) the
period during which the Offering shall be effective, which period shall not
exceed twenty-

                                       2
<PAGE>

seven (27) months beginning with the Offering Date, and the substance of the
provisions contained in paragraphs 5 through 8, inclusive.

         (b) If an employee has more than one (1) right outstanding under the
Plan, unless he or she otherwise indicates in agreements or notices delivered
hereunder, a right with a lower exercise price (or an earlier-granted right if
two (2) rights have identical exercise prices), will be exercised to the fullest
possible extent before a right with a higher exercise price (or a later-granted
right if two (2) rights have identical exercise prices) will be exercised.

5.       ELIGIBILITY.

         (a) Rights may be granted only to employees of the Company or, as the
Board or the Committee may designate as provided in subparagraph 2(b), to
employees of any Affiliate of the Company. Except as provided in subparagraph
5(b), an employee of the Company or any Affiliate shall not be eligible to be
granted rights under the Plan unless, on the Offering Date, such employee has
been in the employ of the Company or any Affiliate for such continuous period
preceding such grant as the Board or the Committee may require, but in no event
shall the required period of continuous employment be greater than two (2)
years. In addition, unless otherwise determined by the Board or the Committee
and set forth in the terms of the applicable Offering, no employee of the
Company or any Affiliate shall be eligible to be granted rights under the Plan
unless, on the Offering Date, such employee's customary employment with the
Company or such Affiliate is for at least twenty (20) hours per week and at
least five (5) months per calendar year.

         (b) The Board or the Committee may provide that each person who, during
the course of an Offering, first becomes an eligible employee of the Company or
designated Affiliate will, on a date or dates specified in the Offering which
coincides with the day on which such person becomes an eligible employee or
occurs thereafter, receive a right under that Offering, which right shall
thereafter be deemed to be a part of that Offering. Such right shall have the
same characteristics as any rights originally granted under that Offering, as
described herein, except that:

               (i) the date on which such right is granted shall be the
"Offering Date" of such right for all purposes, including determination of the
exercise price of such right;

              (ii) the period of the Offering with respect to such right shall
begin on its Offering Date and end coincident with the end of such Offering; and

             (iii) the Board or the Committee may provide that if such person
first becomes an eligible employee within a specified period of time before the
end of the Offering, he or she will not receive any right under that Offering.

         (c) No employee shall be eligible for the grant of any rights under the
Plan if, immediately after any such rights are granted, such employee owns stock
possessing five percent (5%) or more of the total combined voting power or value
of all classes of stock of the Company or of any Affiliate. For purposes of this
subparagraph 5(c), the rules of Section 424(d) of the Code shall apply in
determining the stock ownership of any employee, and stock which such

                                       3
<PAGE>

employee may purchase under all outstanding rights and options shall be treated
as stock owned by such employee.

         (d) An eligible employee may be granted rights under the Plan only if
such rights, together with any other rights granted under "employee stock
purchase plans" of the Company and any Affiliates, as specified by Section
423(b)(8) of the Code, do not permit such employee's rights to purchase stock of
the Company or any Affiliate to accrue at a rate which exceeds twenty five
thousand dollars ($25,000) of fair market value of such stock (determined at the
time such rights are granted) for each calendar year in which such rights are
outstanding at any time.

         (e) Officers of the Company and any designated Affiliate shall be
eligible to participate in Offerings under the Plan; provided, however, that the
Board may provide in an Offering that certain employees who are highly
compensated employees within the meaning of Section 423(b)(4)(D) of the Code
shall not be eligible to participate.

6.       RIGHTS; PURCHASE PRICE.

         (a) On each Offering Date, each eligible employee, pursuant to an
Offering made under the Plan, shall be granted the right to purchase up to the
number of shares of Common Stock of the Company purchasable with a percentage
designated by the Board or the Committee not exceeding fifteen percent (15%) of
such employee's Earnings (as defined in subparagraph 7(a)) during the period
which begins on the Offering Date (or such later date as the Board or the
Committee determines for a particular Offering) and ends on the date stated in
the Offering, which date shall be no later than the end of the Offering. The
Board or the Committee shall establish one (1) or more dates during an Offering
(the "Purchase Date(s)") on which rights granted under the Plan shall be
exercised and purchases of Common Stock carried out in accordance with such
Offering.

         (b) In connection with each Offering made under the Plan, the Board or
the Committee may specify a maximum number of shares that may be purchased by
any employee as well as a maximum aggregate number of shares that may be
purchased by all eligible employees pursuant to such Offering. In addition, in
connection with each Offering that contains more than one (1) Purchase Date, the
Board or the Committee may specify a maximum aggregate number of shares which
may be purchased by all eligible employees on any given Purchase Date under the
Offering. If the aggregate purchase of shares upon exercise of rights granted
under the Offering would exceed any such maximum aggregate number, the Board or
the Committee shall make a pro rata allocation of the shares available in as
nearly a uniform manner as shall be practicable and as it shall deem to be
equitable.

          (c) The purchase price of stock acquired pursuant to rights granted
under the Plan shall be not less than the lesser of:

               (i) an amount equal to eighty-five percent (85%) of the fair
market value of the stock on the Offering Date; or

               (ii) an amount equal to eighty-five percent (85%) of the fair
market value of the stock on the Purchase Date.

7.       PARTICIPATION; WITHDRAWAL; TERMINATION.

         (a) An eligible employee may become a participant in the Plan pursuant
  to an Offering by delivering an enrollment agreement to the Company within the
  time specified in the Offering, in such form as the Company provides. Each
  such agreement shall authorize payroll deductions of up to the maximum
  percentage specified by the Board or the Committee of such employee's Earnings
  during the Offering. "Earnings" is defined as an employee's regular salary or
  wages (including amounts thereof elected to be deferred by the employee, that
  would otherwise have been paid, under any arrangement established by the
  Company that is intended to comply with Section 125, Section 401(k), Section
  402(e)(3), Section 402(h) or section 403(b) of the Code, and also including
  any deferrals under a non-qualified deferred compensation plan or arrangement
  established by the Company), and also, if determined by the Board or the
  Committee and set forth in the terms of the Offering, may include any or all
  of the following: (i) overtime pay, (ii) commissions, (iii) bonuses, incentive
  pay, profit sharing and other remuneration paid directly to the employee,
  and/or (iv) other items of remuneration not specifically excluded pursuant to
  the Plan. Earnings shall not include the cost of employee benefits paid for by
  the Company or an Affiliate, education or tuition reimbursements, imputed
  income arising under any group insurance or benefit program, traveling
  expenses, business and moving expense reimbursements, income received in
  connection with stock options, contributions made by the Company or an
  Affiliate under any employee benefit plan, and similar items of compensation,
  as determined by the Board or the Committee. Notwithstanding the foregoing,
  the Board or Committee may modify the definition of "Earnings" with respect to
  one or more Offerings as the Board or Committee determines appropriate. The
  payroll deductions made for each participant shall be credited to an account
  for such participant under the Plan and shall be deposited with the general
  funds of the Company. A participant may reduce (including to zero) or increase
  such payroll deductions, and an eligible employee may begin such payroll
  deductions, after the beginning of any Offering only as provided for in the
  Offering. A participant may make additional payments into his or her account
  only if specifically provided for in the Offering and only if the participant
  has not had the maximum amount withheld during the Offering.

         (b) At any time during an Offering, a participant may terminate his or
her payroll deductions under the Plan and withdraw from the Offering by
delivering to the Company a notice of withdrawal in such form as the Company
provides. Such withdrawal may be elected at any time prior to the end of the
Offering except as provided by the Board or the Committee in the Offering. Upon
such withdrawal from the Offering by a participant, the Company shall distribute
to such participant all of his or her accumulated payroll deductions (reduced to
the extent, if any, such deductions have been used to acquire stock for the
participant) under the Offering, without interest, and such participant's
interest in that Offering shall be automatically terminated. A participant's
withdrawal from an Offering will have no effect upon such participant's
eligibility to participate in any other Offerings under the Plan but such
participant will be required to deliver a new enrollment agreement in order to
participate in subsequent Offerings under the Plan.

         (c) Rights granted pursuant to any Offering under the Plan shall
terminate immediately upon cessation of any participating employee's employment
with the Company and any designated Affiliate, for any reason, and the Company
shall distribute to such terminated

                                       5
<PAGE>

employee all of his or her accumulated payroll deductions (reduced to the
extent, if any, such deductions have been used to acquire stock for the
terminated employee), under the Offering, without interest.

         (d) Rights granted under the Plan shall not be transferable by a
participant other than by will or the laws of descent and distribution, or by a
beneficiary designation as provided in paragraph 14, and during a participant's
lifetime, shall be exercisable only by such participant.

8.       EXERCISE.

         (a) On each Purchase Date specified therefor in the relevant Offering,
each participant's accumulated payroll deductions and other additional payments
specifically provided for in the Offering (without any increase for interest)
will be applied to the purchase of whole shares of stock of the Company, up to
the maximum number of shares permitted pursuant to the terms of the Plan and the
applicable Offering, at the purchase price specified in the Offering. No
fractional shares shall be issued upon the exercise of rights granted under the
Plan. The amount, if any, of accumulated payroll deductions remaining in each
participant's account after the purchase of shares which is less than the amount
required to purchase one share of Common Stock on the final Purchase Date of an
Offering shall be held in each such participant's account for the purchase of
shares under the next Offering under the Plan, unless such participant withdraws
from such next Offering, as provided in subparagraph 7(b), or is no longer
eligible to be granted rights under the Plan, as provided in paragraph 5, in
which case such amount shall be distributed to the participant after such final
Purchase Date, without interest. The amount, if any, of accumulated payroll
deductions remaining in any participant's account after the purchase of shares
which is equal to the amount required to purchase one or more whole shares of
Common Stock on the final Purchase Date of an Offering shall be distributed in
full to the participant after such Purchase Date, without interest.

         (b) No rights granted under the Plan may be exercised to any extent
unless the shares to be issued upon such exercise under the Plan (including
rights granted thereunder) are covered by an effective registration statement
pursuant to the Securities Act of 1933, as amended (the "Securities Act") and
the Plan is in material compliance with all applicable state, foreign and other
securities and other laws applicable to the Plan. If on a Purchase Date in any
Offering hereunder the Plan is not so registered or in such compliance, no
rights granted under the Plan or any Offering shall be exercised on such
Purchase Date, and the Purchase Date shall be delayed until the Plan is subject
to such an effective registration statement and such compliance, except that the
Purchase Date shall not be delayed more than twelve (12) months and the Purchase
Date shall in no event be more than twenty-seven (27) months from the Offering
Date. If on the Purchase Date of any Offering hereunder, as delayed to the
maximum extent permissible, the Plan is not registered and in such compliance,
no rights granted under the Plan or any Offering shall be exercised and all
payroll deductions accumulated during the Offering (reduced to the extent, if
any, such deductions have been used to acquire stock) shall be distributed to
the participants, without interest.

                                       6

9.       COVENANTS OF THE COMPANY.

         (a) During the terms of the rights granted under the Plan, the Company
shall keep available at all times the number of shares of Common Stock required
to satisfy such rights.

         (b) The Company shall seek to obtain from each federal, state, foreign
or other 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 rights granted under the Plan. 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 rights unless and until
such authority is obtained.

10.      USE OF PROCEEDS FROM STOCK.

         Proceeds from the sale of stock pursuant to rights granted under the
Plan shall constitute general funds of the Company.

11.      RIGHTS AS A STOCKHOLDER.

         A participant shall not be deemed to be the holder of, or to have any
of the rights of a holder with respect to, any shares subject to rights granted
under the Plan unless and until the participant's shareholdings acquired upon
exercise of rights under the Plan are recorded in the books of the Company (or
its transfer agent).

12.      ADJUSTMENTS UPON CHANGES IN STOCK.

         (a) If any change is made in the stock subject to the Plan, or subject
to any rights granted under the Plan (through merger, consolidation,
reorganization, recapitalization, 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 and outstanding rights will
be appropriately adjusted in the class(es) and maximum number of shares subject
to the Plan and the class(es) and number of shares and price per share of stock
subject to outstanding rights. 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 "transaction not involving the receipt of consideration by
the Company.")

         (b) In the event of: (1) a dissolution or liquidation of the Company;
(2) a sale of all or substantially all of the assets of the Company; (3) a
merger or consolidation in which the Company is not the surviving corporation;
(4) a reverse merger in which the Company is the surviving corporation but the
shares of the Company's Common Stock outstanding immediately preceding the
merger are converted by virtue of the merger into other property, whether in the
form of securities, cash or otherwise; (5) the acquisition by any person, entity
or group within the meaning of Section 13(d) or 14(d) of the Securities Exchange
Act of 1934, as amended (the "Exchange Act"), or any comparable successor
provisions (excluding any employee benefit plan, or related trust, sponsored or
maintained by the Company or any Affiliate of the Company) of the beneficial
ownership (within the meaning of Rule 13d-3 promulgated under the Exchange

                                       7
<PAGE>

Act, or comparable successor rule) of securities of the Company representing at
least fifty percent (50%) of the combined voting power entitled to vote in the
election of directors; or (6) the individuals who, as of the date of the
adoption of this Plan, are members of the Board (the "Incumbent Board"; (if the
election, or nomination for election by the Company's stockholders, of a new
director was approved by a vote of at least fifty percent (50%) of the members
of the Board then comprising the Incumbent Board, such new director shall upon
his or her election be considered a member of the Incumbent Board) cease for any
reason to constitute at least fifty percent (50%) of the Board; then the Board
in its sole discretion may take any action or arrange for the taking of any
action among the following: (i) any surviving or acquiring corporation may
assume outstanding rights or substitute similar rights for those under the Plan,
(ii) such rights may continue in full force and effect, or (iii) all
participants' accumulated payroll deductions may be used to purchase Common
Stock immediately prior to or within a reasonable period of time following the
transaction described above and the participants' rights under the ongoing
Offering terminated.

13.      AMENDMENT OF THE PLAN OR OFFERINGS.

         (a) The Board at any time, and from time to time, may amend the Plan or
the terms of one or more Offerings. However, except as provided in paragraph 12
relating to adjustments upon changes in stock, no amendment shall be effective
unless approved by the stockholders of the Company within twelve (12) months
before or after the adoption of the amendment, where the amendment will:

               (i) Increase the number of shares reserved for rights under the
Plan;

               (ii) Modify the provisions as to eligibility for participation in
the Plan or an Offering (to the extent such modification requires stockholder
approval in order for the Plan to obtain employee stock purchase plan treatment
under Section 423 of the Code or to comply with the requirements of Rule 16b-3
promulgated under the Exchange Act, or any comparable successor rule ("Rule
16b-3"); or

               (iii) Modify the Plan or an Offering in any other way if such
modification requires stockholder approval in order for the Plan to obtain
employee stock purchase plan treatment under Section 423 of the Code or to
comply with the requirements of Rule 16b-3.

It is expressly contemplated that the Board may amend the Plan or an Offering in
any respect the Board deems necessary or advisable to provide eligible employees
with the maximum benefits provided or to be provided under the provisions of the
Code and the regulations promulgated thereunder relating to employee stock
purchase plans and/or to bring the Plan and/or rights granted under an Offering
into compliance therewith.

         (b) The Board may, in its sole discretion, submit any amendment to the
Plan or an Offering for stockholder approval.

         (c) Rights and obligations under any rights granted before amendment of
the Plan or Offering shall not be impaired by any amendment of the Plan, except
with the consent of the person to whom such rights were granted, or except as
necessary to comply with any laws or

                                       8
<PAGE>

governmental regulations, or except as necessary to ensure that the Plan and/or
rights granted under an Offering comply with the requirements of Section 423 of
the Code.

14.      DESIGNATION OF BENEFICIARY.

         (a) A participant may file a written designation of a beneficiary who
is to receive any shares and cash, if applicable, from the participant's account
under the Plan in the event of such participant's death subsequent to the end of
an Offering but prior to delivery to the participant of such shares and cash. In
addition, a participant may file a written designation of a beneficiary who is
to receive any cash from the participant's account under the Plan in the event
of such participant's death during an Offering.

         (b) Such designation of beneficiary may be changed by the participant
at any time by written notice in the form prescribed by the Company. In the
event of the death of a participant and in the absence of a beneficiary validly
designated under the Plan who is living (or if an entity, is otherwise in
existence) at the time of such participant's death, the Company shall deliver
such shares and/or cash to the executor or administrator of the estate of the
participant, or if no such executor or administrator has been appointed (to the
knowledge of the Company), the Company, in its sole discretion, may deliver such
shares and/or cash to the spouse or to any one (1) or more dependents or
relatives of the participant, or if no spouse, dependent or relative is known to
the Company, then to such other person as the Company may determine.

15.      TERMINATION OR SUSPENSION OF THE PLAN.

         (a) The Board in its discretion, may suspend or terminate the Plan at
any time. The Plan shall automatically terminate if all the shares subject to
the Plan pursuant to subparagraph 3(a) are issued. No rights may be granted
under the Plan while the Plan is suspended or after it is terminated.

         (b) Rights and obligations under any rights granted while the Plan is
in effect shall not be impaired by suspension or termination of the Plan, except
as expressly provided in the Plan or with the consent of the person to whom such
rights were granted, or except as necessary to comply with any laws or
governmental regulation, or except as necessary to ensure that the Plan and/or
rights granted under an Offering comply with the requirements of Section 423 of
the Code.

16.      EFFECTIVE DATE OF PLAN.

         The Plan shall become effective on the same day on which the Company's
shareholders approve the Plan pursuant to vote of the shareholders held at the
duly noticed Annual Shareholders Meeting in 1999.

17.      CHOICE OF LAW.

         All questions concerning the construction, validity and interpretation
of this Plan shall be governed by the law of the State of California, without
regard to such state's conflict of laws rules.
