EXHIBIT 10.39


                  THE 1998 VENTURE CAPITAL RETENTION PROGRAM
                           ADOPTED FEBRUARY 19, 1998
                             AMENDED JUNE 18, 1998
                                       

Silicon Valley Bank ("Bank") recognizes the valuable contributions made by
certain key employees of the Bank and wishes to retain these employees who are
critical to the Bank's long-term success.  In that regard, the Bank has
established a retention program (the "Retention Program") where these employees
can share in distributions on Silicon Valley Bancshares' (the "Company")
investments in certain venture capital funds ("VC Funds").  These investments
have been made by the Company under its existing venture capital investment
program (the "VC Program").  Employees' continued participation in
distributions from VC Funds generally will be subject to such employees'
continued employment with the Bank.

- - DEFINITIONS

   - DESIGNATED COMMITMENTS.  $4.25 million of the Company's existing
     commitments under the VC Program, whether funded or unfunded, which the
     Company has earmarked for the Retention Program.

   - DISTRIBUTIONS.  Payments made by a VC Fund (under Designated Commitments)
     to the Company as an investor in the VC Fund.

   - PARTICIPANTS.  Those employees designated by the Bank's Executive
     Committee to participate in the Retention Program.

   - VC PARTICIPANT DISTRIBUTIONS.  Those Distributions made to Participants
     under the Retention Program.

- - HOW THE RETENTION PROGRAM WORKS

   - PARTICIPANTS' POTENTIAL INTEREST IN VC PROGRAM AGGREGATES $850,000 (20% OF
     DESIGNATED COMMITMENTS).  For the 1998 Retention Program, the Company will
     establish a "book entry" account for Participants, covering 20% of the
     Designated Commitments ($850,000 in the aggregate).

   - PARTICIPANTS SHARE IN $850,000 PROGRAM PRO RATA AS DETERMINED BY BANK'S
     EXECUTIVE COMMITTEE.  The Bank's Executive Committee shall determine the
     Participants' respective interests in the 1998 $850,000 Retention Program,
     and in turn, respective interests in the VC Participant Distributions.
     Each such Participant's "book entry" interest shall be deemed his or her
     "VC Participant Amount," and each such Participant's pro rata share in VC
     Participant Distributions shall be referred to as such Participant's "Pro
     Rata" share.  For example, a Participant allocated a $15,000 "book entry"
     interest in the $850,000 Retention Program would have been granted a
     $15,000 

                                       1


     Participant Amount (1.8% Pro Rata share of the 1998 Retention Program),
     and would be entitled to 1.8% of VC Participant Distributions made in any 
     calendar year during the term of the Retention Program (which VC 
     Participant Distributions to Participants aggregate to 20% of Distributions
     to the Company).  (See discussion below regarding how VC Participant 
     Distributions are made.)

   - PARTICIPANTS' 20% INTEREST IN DISTRIBUTIONS WILL BE RESERVED FOR
     PARTICIPANTS AND PAID IN JANUARY OF THE FOLLOWING YEAR.  Upon receipt of
     Distributions to the Company, the Company will set aside the VC
     Participant Distributions allocable to all Participants (e.g., 20% of the
     total Distributions to the Company made during the applicable calendar
     year).  (See discussion below regarding VC Participant Distributions being
     paid the following January.)

   - ANNUAL VC PARTICIPANT DISTRIBUTIONS WILL BE MADE TO PARTICIPANTS IN
     JANUARY (FOR DISTRIBUTIONS MADE IN THE PRECEDING YEAR).  All Distributions
     reserved for Participants in a given calendar year will be paid to the
     Participants in January following the year of distribution, provided,
     however, that any Distributions which the Company may receive in the form
     of stock shall be retained by the Company until such time as the Company,
     in its sole discretion, liquidates the stock.  The Participants' Pro Rata
     share in proceeds realized from liquidation of such stock will then be
     paid to the Participants in January following the year of liquidation.

   - PARTICIPANTS RECEIVE DISTRIBUTIONS ONLY TO THE EXTENT RECEIVED BY THE
     COMPANY.  VC Participant Distributions will be paid to the Participants
     only to the extent they are received by the Company (subject to discussion
     below under "Changes That Could Affect the Award").  Therefore, if no
     Distributions are paid to the Company in a given year, the Participants
     will not receive any VC Participant Distributions in January of the
     following year.

   - PARTICIPANTS HAVE A 20% INTEREST IN UNFUNDED DESIGNATED COMMITMENTS.  Upon
     the expiration of the Company's commitment to fund a VC Fund classified as
     a Designated Commitment (the "Commitment Termination Date"--in most cases,
     this will be the expiration of the term of the VC Fund), 20% of unfunded
     commitments made to that VC Fund, will be paid to Participants (Pro Rata)
     as Distributions in January following the year in which the Commitment
     Termination Date occurs.

   - 1998 RETENTION PROGRAM (INCLUDING BANK'S OBLIGATION TO PAY DISTRIBUTIONS
     ON FUNDED DESIGNATED COMMITMENTS) TERMINATES IN 2010.  In 2010, the Bank's
     obligation to distribute to the Participants any Distributions, or
     unfunded commitments pertaining to Designated Commitments, will terminate.
     Final VC Participant Distributions, and Pro Rata interests in unfunded
     commitments, will be paid to Participants in January, 2011.

   - NO ASSURANCE OF ANY DISTRIBUTIONS.  In light of the speculative nature of
     investments in the VC Funds, the Company and the Bank make no assurances
     whatsoever as to payment of any VC Participant Distributions to
     Participants and Participants shall have no claim on the Company or on the
     assets of the Company in the event of a failure of a Participant to
     receive any payment of amounts under the Retention Program for which the
     Company 

                                       2


     did not receive a Distribution (subject to discussion below under "Changes
     That Could Affect the Award").

   - DISTRIBUTIONS SHOULD BE TAXABLE AS ORDINARY INCOME.  For income tax
     purposes, VC Participant Distributions are taxable as ordinary income to
     Participants and are subject to withholding of income and employment taxes
     at the time of payment.  Participants should consult with their own
     personal tax advisors to confirm the tax treatment of VC Participant
     Distributions.

- - ELIGIBILITY

   - CONTINUED EMPLOYMENT REQUIRED.  To be eligible to receive VC Participant
     Distributions, Participants must be employed by the Bank on the date VC
     Participant Distributions are paid to Participants.  A Participant who
     terminates employment with the Bank forfeits such Participant's Pro Rata
     interest in future VC Participant Distributions and any further interest
     in such Participant's VC Participant Amount.  (Any such forfeited
     interests will remain the property of the Company, and specifically, will
     not be allocated among remaining Participants in the Retention Program.)
     Also, a Participant who terminates employment with the Bank prior to the
     date on which VC Participant Distributions are paid to Participants
     forfeits any accrued VC Participant Distributions set aside for the
     Participant's benefit.  The terms in this paragraph are subject to
     discussion below under "Changes in Employment Status."

- - CHANGES THAT COULD AFFECT THE AWARD

   - PERFORMANCE STANDARDS.  Awards are payable only to active employees who
     maintain performance ratings of 3 or higher.  A Participant whose
     performance rating is sub-standard (rating below 3) forfeits any accrued
     VC Participant Distributions set aside for the Participant's benefit,
     which the Participant otherwise would have received in January following
     the sub-standard performance year, except in the sole discretion of the
     Bank's Executive Committee.  Any forfeitures arising from a Participant's
     sub-standard performance will remain the property of the Company.  If and
     as the Participant's performance improves to a rating of 3 or above in a
     subsequent year, the Participant will again become eligible to receive VC
     Participant Distributions for such subsequent year or years.

   - CHANGES IN EMPLOYMENT STATUS.  A Participant must be employed by the Bank
     at the time VC Participant Distributions are paid (January of each year)
     in order to receive such Participant's Pro Rata share in the VC
     Participant Distributions.  Notwithstanding the foregoing:

     - DISABILITY.  For the first eighteen (18) months following the adoption
       of this Retention Program (e.g., February 19, 1998), any Participant 
       whose employment terminates due to the Participant's disability shall be
       entitled to the Cashout Amount.

     "Cashout Amount" shall mean an amount equal to the aggregate of such
       Participant's (1) VC Participant Amount (less (a) VC Participant
       Distributions then to-date made on such Designated Commitments, (b) VC
       Participant Distributions made pursuant to 

                                       3


       subsection (2) immediately below, and (c) any payments then-to-date made
       on unfunded Designated Commitments) and (2) then-accrued VC Participant
       Distribution (prior to the regular January VC Participant Distribution 
       date).

     A Participant whose employment terminates due do the Participant's
       disability after eighteen (18) months following the adoption of this
       Retention Program shall be entitled to receive the Present Value of the
       Participant's VC Participant Amount.

     "Present Value" shall be determined by conducting an appraisal of the
       Designated Commitments and determining the fair market value of the
       Designated Commitments discounted to present value.  The appraisal shall
       be prepared by an independent business valuation appraiser ("Independent
       Appraiser").  The appraisal shall be dated within three (3) months prior
       to the termination of the Participant pursuant to this section or three
       (3) months after such termination.  The Present Value established by the
       Independent Appraiser is conclusive and binding upon the parties.  The
       Company will pay the fees and expenses charged by the Independent
       Appraiser.

     - DEATH.  In the event of death of a Participant within eighteen (18)
       months following the adoption of this Retention Program, the
       Participant's estate or beneficiary shall be entitled to receive the
       Cashout Amount.

     In the event of death of a Participant after eighteen (18) months
       following the adoption of this Retention Program, the Participant's
       estate or beneficiary shall be entitled to receive the Present Value of
       the Participant's VC Participant Amount.

     - RETIREMENT.  If within the first eighteen (18) months following the
       adoption of this Retention Program, a Participant  retires from
       employment with the Bank following the Participant's 55th birthday, the
       Participant shall be entitled to receive the Cashout Amount.

     If a Participant retires after eighteen (18) months following the
       adoption of this Retention Program, the Bank's President and Chief
       Executive Officer ("CEO"), in such CEO's sole discretion, shall
       determine if the Participant shall:  (1) be entitled to receive the
       Present Value of the Participant's VC Participant Amount; or (2) be
       permitted to receive future VC Participant Distributions ("Continued
       Participation").

     - CHANGE TO CONSULTANT STATUS OR OTHER SPECIAL CIRCUMSTANCES.  If
       within the first eighteen (18) months following the adoption of this
       Retention Program, a Participant leaves the Bank's employment, including
       where such Participant becomes a consultant to the Bank, the Participant
       may be entitled to the Cashout Amount if the CEO, in such CEO's sole
       discretion, determines that the Participant continues to add value to
       the Bank ("Adding Value").  Factors to be considered in determining
       Adding Value include, but are not limited to: (1) the Participant
       promoting and supporting the Bank in the marketplace and community; (2)
       the Participant promoting and supporting the interests of the Bank with
       clients, venture capitalists, and prospects; (3) the Participant
       promoting and supporting the interests of the Bank through civic
       activities; (4) the Participant continuing to provide a service to the
       Bank (e.g., as a consultant); (5) the Participant continuing to add
       value to a Bank-related project; or (6) the Participant providing
       referrals to the Bank.  The CEO shall make this 

                                       4


       determination one-time only, within three (3) months after the 
       termination of the Participant pursuant to this section.  In the absence
       of the CEO's determination to provide the special benefits provided in 
       this section, a Participant who leaves the Bank's employment forfeits 
       such Participant's accrued and future Pro Rata interest in VC Participant
       Distributions and any further interest in such Participant's VC 
       Participant Amount, in accordance with the discussion above under 
       "Eligibility."

       If a Participant leaves the Bank's employment after eighteen (18) months
       following the adoption of this Retention Program, the Participant may be
       entitled to either:  (1) receive the Present Value of the Participant's
       VC Participant Amount; or (2) Continued Participation (with it being in
       the CEO's sole discretion as to which alternative) IF the CEO, in such 
       CEO's sole discretion, determines that the Participant is Adding Value.
       The CEO shall make this determination one-time only, within three (3) 
       months after the termination of the Participant pursuant to this section.
       In the absence of the CEO's determination to provide the special benefits
       provided in this section, a Participant who leaves the Bank's employment
       forfeits such Participant's accrued and future Pro Rata interest in VC 
       Participant Distributions and any further interest in such Participant's
       VC Participant Amount, in accordance with the discussion above under 
       "Eligibility."

     - CHANGE IN CONTROL.  If within eighteen (18) months following the
       adoption of this Retention Program, there is a change in control of the
       Bank, a Participant who undergoes a "Covered Termination" (as such term,
       "Covered Termination", is defined under the Bank's change in control
       program), such Participant shall be entitled to receive the Cashout
       Amount.

     If a change in control of the Bank occurs after eighteen months
       following the adoption of this Retention Program and a Participant
       undergoes a "Covered Termination" (as such term, "Covered Termination,"
       is defined under the Bank's change in control program), the CEO, in such
       CEO's sole discretion, shall determine if the Participant shall be
       entitled to:  (1) receive the Present Value of the Participant's VC
       Participant Amount; or (2) Continued Participation.

   - REGULATORY LIMITATIONS.  Payment of any VC Participant Distributions may
     be postponed, reduced and/or eliminated in certain circumstances pursuant
     to applicable law or regulation or as otherwise determined by the Bank's
     federal and state regulators.

   - CAPITAL LIMITATIONS.  Payment of any VC Participant Distributions shall be
     deferred during such time periods when any of the Bank's capital ratios
     (total capital ratio, Tier1 capital ratio or Tier 1 leverage ratio) is
     below the trigger threshold levels set forth in the Bank's Capital Policy
     (as such policy may be amended from time to time).  Additionally, such
     payments shall be deferred if after giving effect to then-payable VC
     Participant Distributions, the Bank's capital ratios will be below the
     trigger threshold levels.  In such cases of deferral, payment of the VC
     Participant Distributions will be deferred until all of the Bank's capital
     ratios are restored to the trigger threshold levels (with such deferred
     payments being made once the ratios have been restored [unless otherwise
     prohibited or restricted as specified in the subsection headed "Regulatory
     Limitations"], and 

                                       5


     specifically, even where payments then would be made prior to the regular
     January VC Participant Distribution date).

   - VIOLATION OF FIREWALLS REQUIREMENTS.  Any violation of the firewalls
     requirements set forth in the Company's Venture Capital Fund Investment
     Policies and Procedures ("VC Policies and Procedures") (by any
     Participant), in the Executive Committee's sole discretion, shall cause a
     forfeiture of such Participant's then-accrued and future VC Participant
     Distributions.

- - ADMINISTRATION

   - ADMINISTRATION BY FUNDS MANAGEMENT GROUP AND COMPENSATION AND BENEFITS
     DEPARTMENT.  The Retention Program will be administered by the Company's
     Funds Management Group and the Bank's Compensation and Benefits
     Department.

     - INVESTMENT DECISIONS MADE BY FUNDS MANAGEMENT GROUP.  The Company's
       Funds Management Group shall be solely responsible for all investment
       decisions relating to the VC Program in accordance with the Company's VC
       Policies and Procedures.

- - COMPLIANCE WITH FIREWALLS REQUIREMENTS IN VENTURE CAPITAL FUND INVESTMENT
  POLICIES AND PROCEDURES

   - COMPLIANCE BY BANK OFFICERS.  As noted in the Bank's Code of Ethics (the
     "Code"), Bank officers should be circumspect regarding behavior that even
     may appear that such officers are benefiting from their relationship with
     the Bank, even where such behavior does not constitute a violation of the
     Code.  A violation of the Code shall have occurred if a Bank officer, in
     making a credit decision, is deemed to have compromised the Bank's
     interest by putting such officer's personal investment interest (in
     potential VC Participant Distributions or otherwise) ahead of the Bank's
     interest.  Any such violation may result in disciplinary actions up to and
     including termination of employment.

   - COMPLIANCE BY FMG MEMBERS (COMPANY OFFICERS).  As noted in the Code,
     Company officers should be circumspect regarding behavior that even may
     appear that such officers are benefiting from their relationship with the
     Company and the Bank, even where such behavior does not constitute a
     violation of the Code.  A violation of the Code shall have occurred if a
     Company officer is deemed to have compromised the Bank's interest by
     influencing a credit decision in a manner that places such officer's
     personal investment interest (in potential VC Participant Distributions or
     otherwise) ahead of the Bank's or the Company's interest.  Such violation
     shall give rise to such disciplinary actions noted  in the immediately-
     preceding section.

   - PERIODIC AUDITS TO CONFIRM COMPLIANCE.  Compliance with the above-
     described provision of the Code will be confirmed in the periodic
     compliance audits performed pursuant to Section 6.0 (regarding firewalls)
     of the VC Policies and Procedures.  The 

                                       6


     compliance auditors will bring any violation of the firewalls requirements
     to the attention of management (or the Board) of the Company or the Bank,
     as appropriate.

   - VIOLATION OF FIREWALLS REQUIREMENTS.  Any violation of the firewalls
     requirements, in addition to giving rise to disciplinary action, may
     result in the Participant's forfeiting any then-accrued VC Participant
     Distributions, as well as all future VC Participant Distributions (in
     accordance with the section above headed "Violation of Firewalls
     Requirements").

- - SEVERABILITY

   - TERMS AND PROVISIONS ARE SEVERABLE.  If any term or provision of this
     Program is held invalid or unenforceable to any extent, the remainder of
     this Program shall not be affected and each term and provision of this
     Program shall be valid and enforceable to the fullest extent permitted by
     law.

- - ARBITRATION

   - DISPUTES TO BE SETTLED BY ARBITRATION.  Any and all disputes or
     controversies, arising from or regarding the interpretation, performance,
     enforcement or termination of the Retention Program will be resolved by
     final and binding arbitration under the procedures set forth in the
     Arbitration Procedure and the then existing Rules of Practice and
     Procedure of the Judicial Arbitration and Mediation Services, Inc. 
     ("JAMS") or the rules of practice and procedure of any successor entity to
     JAMS.


     THE COMPANY AND THE BANK EACH RESERVES THE RIGHT TO CHANGE, AMEND,
          SUSPEND, OR TERMINATE THE RETENTION PROGRAM AT ANY TIME.  THIS
          PROGRAM DOES NOT CREATE A CONTRACT OF EMPLOYMENT BETWEEN SILICON
          VALLEY BANK AND ANY EMPLOYEE OR BETWEEN SILICON VALLEY BANCSHARES
          AND ANY EMPLOYEE.
