                            OF SILICON VALLEY BANCSHARES


     Pursuant to the Indenture dated as of May 22, 1998 (the "Indenture"), 
between Silicon Valley Bancshares, a California corporation (the "Company") 
and Wilmington Trust Company, as Debenture Trustee (the "Debenture Trustee") 
and resolutions adopted by the Pricing Committee of the Company's Board of 
Directors on May 19, 1998; this Officers' Certificate is being delivered to 
the Debenture Trustee to establish the terms of one series of securities (the 
"Securities") in accordance with Section 3.1 of the Indenture, to establish 
the form of the Securities of such series in accordance with Section 2.1 of 
the Indenture, to request the authentication and delivery of the Securities 
of such series pursuant to Section 3.3 of the Indenture and to comply with 
the provisions of Section 1.2 of the Indenture.  This Officers' Certificate 
shall be treated for all purposes under the Indenture as a supplemental 
indenture thereto.

     All conditions precedent provided for in the Indenture relating to the 
establishment of (i) a series of Securities, (ii) the form of Securities of 
such series, and (iii) authentication of such series of Securities, have been 
complied with.

     Capitalized terms used but not otherwise defined herein shall have the 
meanings assigned to them in the Indenture.

     1.  ESTABLISHMENT OF SERIES OF SECURITIES PURSUANT TO SECTION 3.1 OF THE 
INDENTURE.

     There are hereby established pursuant to Section 3.1 of the Indenture a 
series of Securities which shall have the following terms:

         A   The Securities of such series shall bear the title "8.25% Junior 
Subordinated Deferrable Interest Debentures Due June 15, 2028."

         B.  The aggregate principal amount of such series of Securities to 
be issued pursuant to this Officers' Certificate and Company Order shall be 
limited to $41,237,125 (except for Securities authenticated and delivered 
upon registration of, transfer of, or in exchange for, or in lieu of, other 
Securities of such series pursuant to Section 3.4, 3.5, 3.6, 9.6 or 11.7 of 
the Indenture and except for any Securities which, pursuant to Section 3.3 of 
the Indenture, are deemed never to have been authenticated and delivered 
thereunder).



         C.  The date on which the principal of the Securities is due and 
payable shall be June 15, 2028.

         D.  The Securities shall bear interest at the rate of 8.25% per 
annum (based upon a 360-day year of twelve 30-day months), from and including 
the date of original issuance or from and including the most recent Interest 
Payment Date to which interest has been paid or duly provided for, as the 
case may be, payable quarterly in arrears on the 15th day of March, June, 
September and December in each year (each, an "Interest Payment Date"), 
commencing September 15, 1998, until the principal thereof is paid or made 
available for payment.  The Business Day next preceding an Interest Payment 
Date shall be the "Regular Record Date" for the interest payable on such 
Interest Payment Date.  Accrued interest that is not paid on such applicable 
Interest Payment Date will bear additional interest on the amount thereof (to 
the extent permitted by law) at a rate per annum of 8.25% thereof compounded 
quarterly.

             In addition, so long as no Event of Default with respect to the 
Securities has occurred or is continuing, the Company has the right under the 
Indenture at any time during the term of such Securities to defer the payment 
of interest at any time or from time to time for a period not exceeding 20 
consecutive quarterly periods with respect to each Extension Period, provided 
that no Extension Period may extend beyond the Stated Maturity.  At the end 
of such Extension Period, the Company must pay all interest then accrued and 
unpaid (together with interest thereon at the annual rate of 8.25%, 
compounded quarterly, to the extent permitted by applicable law).

         E.  Principal of and interest on the Securities will be payable, 
and, except as provided in Section 3.5 of the Indenture with respect to a 
Global Security (as defined below), the transfer of the Securities will be 
registrable and Securities will be exchangeable for Securities bearing 
identical terms and provisions at the corporate trust office of Wilmington 
Trust Company in the City of Wilmington, Delaware.

         F.  The Securities will be redeemable in whole at any time and in 
part from time to time, at the option of the Company at any time on or after 
June 15, 2003, subject to the Company having received prior regulatory 
approval if then so required, at a redemption price equal to the accrued and 
unpaid interest on the Securities so redeemed to the date fixed for 
redemption, plus 100% of the principal amount thereof.

             In addition, upon the occurrence of a Tax Event, an Investment 
Company Event or a Capital Treatment Event, the Company may, at its option 
and subject to receipt of prior regulatory approval if then required under 
applicable capital guidelines or policies, prepay the Securities in whole 
(but not in part) at any time within 90 days of the occurrence of such Tax 
Event, Investment Company Event or a Capital Treatment Event, at a redemption 
price equal to the accrued and unpaid interest on the Securities so redeemed 
to the date fixed for redemption, plus 100% of the principal amount thereof.

         G.  The Company shall not be obligated to redeem or purchase any 
Securities pursuant to any sinking fund or analogous provisions or at the 
option of the Holder.



         H.  The Securities will be issued only in fully registered form and 
the authorized minimum denomination of the Securities shall be $25.00 and any 
integral multiple of $25.00 in excess thereof.

         I.  The Securities shall be denominated, and payments of principal 
of (and premium, if any) and interest on the Securities of such series will 
be made, in United States dollars.

         J.  The Securities shall be subject to the Events of Default 
specified in Section 5.1, paragraphs (a) through (e), of the Indenture.

         K.  The portion of the principal amount of the Securities which 
shall be payable upon declaration of acceleration of maturity thereof shall 
not be other than the principal amount thereof. 

         L.  The Securities will be issued in fully registered form, without 
coupons.  The Securities will not be issued in bearer form.

         M.  The amount of payments of principal of and any premium or 
interest on the Securities will not be determined with reference to an index.

         N.  The Securities shall not be issued in the form of a temporary 
Global Security (as defined below).

         O.  The Securities will initially be deposited with, and on behalf 
of, The Depository Trust Company, New York, New York, as Depositary, and will 
be represented by a global security (a "Global Security") registered in the 
name of a nominee of the Depositary.  If, and so long as the Depositary or 
its nominee is the registered holder of any Global Security, the Depositary 
or its nominee, as the case may be, will be considered the sole Holder of the 
Securities of such series represented by such Global Security for all 
purposes under the Indenture and the Securities. 

         P.  The Trustee shall be Paying Agent.

         Q.  The Securities will not be convertible into any other securities 
or property of the Company.  The Securities of any series may not be 
exchanged for Securities of any other series.

         R.  The Trust Agreement, the Amended and Restated Trust Agreement 
and the Guarantee Agreement are in the forms attached hereto as Exhibits A, 
B, and C respectively.

         S.  The Securities are subordinate and subject in right of payment to 



the prior payment in full of all amounts then due and payable in respect of 
all Senior and Subordinated Debt, as provided in the Indenture.

     II.   ESTABLISHMENT OF FORMS OF SECURITIES PURSUANT TO SECTION 2.1 OF 
INDENTURE.

     It is hereby established pursuant to Section 2.1 of the Indenture that 
the Securities shall be substantially in the form attached as Exhibit D 
hereto.

     III.  ORDER FOR THE AUTHENTICATION AND DELIVERY OF SECURITIES PURSUANT 
TO SECTION 3.3 OF THE INDENTURE.

     It is hereby ordered pursuant to Section 3.3 of the Indenture that the 
Trustee authenticate, in the manner provided by the Indenture, Securities in 
the aggregate principal amount of $41,237,125 registered in the name of Cede
