corporation, as Trustee (hereinafter called the "Trustee").

                           RECITALS OF THE COMPANY

     The Company has duly authorized the execution and delivery of this 
Indenture to provide for the issuance from time to time of its unsecured 
junior subordinated debt securities in series (hereinafter called the 
"Securities") of substantially the tenor hereinafter provided, including, 
without limitation, Securities issued to evidence loans made to the Company 
of the proceeds from the issuance from time to time by one or more business

interests in such Trusts (the "Common Securities" and, collectively with the 
Preferred Securities, the Trust Securities), and to provide the terms and 
conditions upon which the Securities are to be authenticated, issued and 
delivered.

     All things necessary to make the Securities, when executed by the 
Company and authenticated and delivered hereunder and duly issued by the 
Company the valid obligations of 



the Company, and to make this Indenture a valid agreement of the Company, in 
accordance with their and its terms, have been done.

     NOW THEREFORE, THIS INDENTURE WITNESSETH:  For and in consideration of 
the premises and the purchase of the Securities by the Holders thereof, it is 
mutually covenanted and agreed, for the equal and proportionate benefit of 
all Holders of the Securities or of any series thereof, as follows:

subordinate and junior in right of payment to such Senior and Subordinated 
Debt pursuant to any provision of such indebtedness for the payment over of 
amounts received on account of such indebtedness to the holders of such 
Senior and Subordinated Debt or otherwise) but for the fact that such Senior

accrued liabilities arising in the ordinary course of business.

decision interpreting or applying such laws or regulations, which amendment 
or change is effective or such prospective change, pronouncement or decision

expressly required, to the Company. Such instrument or instruments (and the 
action embodied therein and evidenced thereby) are herein sometimes referred

Security.

determining the Holders of Outstanding Securities of any series entitled to

given, made or taken by Holders of Securities of such series, PROVIDED that

other Holders, shall be entitled to take the relevant action, whether or not 
such Holders remain Holders after such record date, PROVIDED that no such 
action shall be effective hereunder unless taken on or prior to the 
applicable Expiration Date (as defined below) by Holders of the requisite 
principal amount of Outstanding Securities of such series on such record 
date. Nothing in this paragraph shall be construed to prevent the Company 
from setting a new record date for any action for which a record date has 
previously been set pursuant to this paragraph (whereupon the record date 
previously set shall automatically and with no action by any Person be 
canceled and of no effect), and nothing in this paragraph shall be construed 
to render ineffective any action taken by Holders of the requisite principal 
amount of Outstanding Securities of the relevant series on the date such 
action is taken. Promptly after any record date is set pursuant to this 
paragraph, the Company, at its own expense, shall cause notice of such record 
date, the proposed action by Holders and the applicable Expiration Date to be 
given to the Trustee in writing and to each Holder of Securities of the 
relevant series in the manner set forth in Section 1.6.

     The Trustee may set any day as a record date for the purpose of 
determining the Holders of Outstanding Securities of any series entitled to 
join in the giving or making of (i) any Notice of Default, (ii) any 
declaration of acceleration referred to in Section 5.2, (iii) any request to 
institute proceedings referred to in Section 5.7(b) or (iv) any direction 
referred to in Section 5.12, in each case with respect to Securities of such 
series. If any record date is set pursuant to this paragraph, the Holders of 
Outstanding Securities of such series on such record date, and no other 
Holders, shall be entitled to join in such notice, declaration, request or 
direction, whether or not such Holders remain Holders after such record date, 
PROVIDED that no such action shall be effective hereunder unless taken on or 
prior to the applicable Expiration Date by Holders of the requisite principal 
amount of Outstanding Securities of such series on such record date. Nothing 
in this paragraph shall be construed to prevent the Trustee from setting a 
new record date for any action for which a record date has previously been 
set pursuant to this paragraph (whereupon the record date previously set 
shall automatically and with no action by any Person be canceled and of no 
effect), and nothing in this paragraph shall be construed to render 
ineffective any action taken by Holders of the requisite principal amount of 
Outstanding Securities of the relevant series on the date such action is 
taken. Promptly after any record date is set pursuant to this paragraph, the 
Trustee, at the Company's expense, shall cause notice of such record date, 
the proposed action by Holders and the applicable Expiration Date to be given 
to the Company in writing and to each Holder of Securities of the relevant 
series in the manner set forth in Section 1.6.

     With respect to any record date set pursuant to this Section, the party 
hereto which sets such record dates may designate any day as the "Expiration 
Date" and from time to time may change the Expiration Date to any earlier or 
later day, PROVIDED that no such change shall be effective unless notice of 
the proposed new Expiration Date is given to the other party hereto in 

                                       15


writing, and to each Holder of Securities of the relevant series in the 
manner set forth in Section 10.6, on or prior to the existing Expiration 
Date. If an Expiration Date is not designated with respect to any record date 
set pursuant to this Section, the party hereto which set such record date 
shall be deemed to have initially designated the 180th day after such record 
date as the Expiration Date with respect thereto, subject to its right to 
change the Expiration Date as provided in this paragraph. Notwithstanding the 
foregoing, no Expiration Date shall be later than the 180th day after the 
applicable record date. 

     (g)  Without limiting the foregoing, a Holder entitled hereunder to take 
any action hereunder with regard to any particular Security may do so with 
regard to all or any part of the principal amount of such Security or by one 
or more duly appointed agents each of which may do so pursuant to such 
appointment with regard to all or any part of such principal amount.

the Securities Register, not later than the latest date, and not earlier than 
the earliest date, prescribed for the giving of such notice.  In any case 
where notice to Holders is given by mail, neither the failure to mail such 
notice, nor any defect in any notice so mailed, to any particular Holder 
shall affect the sufficiency of such notice with respect to other Holders.  
Where this Indenture provides for notice in any manner, such notice may be 
waived in writing by the Person entitled to receive such notice, either 
before or after the event, and such waiver shall be the equivalent of such 
notice.  Waivers of notice by Holders shall be filed with the Trustee, but 
such filing shall not be a condition precedent to the validity of any action 
taken in reliance upon such waiver.

     SILICON VALLEY BANCSHARES, a corporation organized and existing under 
the laws of California (hereinafter called the "Company", which term includes 
any successor corporation under the Indenture hereinafter referred to), for 
value received, hereby promises to pay to __________, or registered assigns, 
the principal sum of $_______ Dollars on ________; provided that the Company 
may shorten the Stated Maturity of the principal of this Security to a date 
not earlier than ________.  The Company further promises to pay interest on 
said principal sum from ________ or from the most recent interest payment 
date (each such date, an "Interest Payment Date") on which interest has been 
paid or duly provided for, quarterly (subject to deferral as set forth 
herein) in arrears on the _____ day of _____, _____, _____ and _____ of each 
year commencing ________ at the rate of ____% per annum, until the principal 
hereof shall have become due and payable, plus Additional Interest, if any, 
until the principal hereof is paid or duly provided for or made available for 
payment and on any overdue principal and (without duplication and to the 
extent that payment of such interest is enforceable under applicable law) on 
any overdue installment of interest at the rate of ____% per annum, 
compounded quarterly.  The amount of interest payable for any period shall be 
computed on the basis of twelve 30-day months and a 360-day year.  The amount 
of interest payable for any partial period shall be computed on the basis of 
the number of days elapsed in a 360-day year of twelve 30-day months.  In the 
event that any date on which interest is payable on this Security is not a 
Business Day, then a payment of the interest payable on such date will be 
made on the next succeeding day which is a Business Day (and without any 
interest or other payment in respect of any such delay), with the same force 
and effect as if made on the date the payment was originally payable.  A 
"Business Day" shall mean any day other than a Saturday or Sunday a day on 
which banking institutions in the State of California are authorized or 
required by law or executive order to remain closed or on a day on which the 
Corporate Trust Office of the Trustee, or the principal office of the 
Property Trustee under the Amended and Restated Trust Agreement (hereinafter 
referred to) for [NAME OF TRUST] is closed for business.  The interest 
installment so payable, and punctually paid or duly provided for, on any 
Interest Payment Date will, as provided in the Indenture, be paid to the 
Person in whose name this Security (or one or more Predecessor Securities) is 
registered at the close of business on the Regular Record Date for such 
interest installment, which shall be [INSERT RECORD DATE]  next preceding 
such Interest Payment Date.  Any such interest installment not so punctually 
paid or duly provided for shall forthwith cease to be payable to the Holder 
on such Regular Record Date and may either be paid to the Person in whose 
name this Security (or one or more Predecessor Securities) is registered at 
the close of business on a Special Record Date for the payment of such 
Defaulted Interest to be fixed by the Trustee, notice whereof shall be given 
to Holders of Securities of this series not less than ____ 

                                       19


days prior to such Special Record Date, or be paid at any time in any other 
lawful manner not inconsistent with the requirements of any securities 
exchange on which the Securities of this series may be listed, and upon such 
notice as may be required by such exchange, all as more fully provided in 
said Indenture.

     [IF APPLICABLE INSERT--So long as no Event of Default has occurred and is 
continuing, the Company shall have the right at any time during the term of 
this Security to defer payment of interest on this Security, at any time or 
from time to time, for up to 20 consecutive quarterly interest payment periods 
with respect to each deferral period (each an "EXTENSION PERIOD"), (during 
which Extension Periods the Company shall have the right to make partial 
payments of interest on any Interest Payment Date, and at the end of which 
the Company shall pay all interest then accrued and unpaid (together with 
Additional Interest thereon to the extent permitted by applicable law)); 
PROVIDED, HOWEVER, that no Extension Period shall extend beyond the Stated 
Maturity of the principal of this Security; PROVIDED, FURTHER, that during 
any such Extension Period, the Company shall not, and shall not permit any 
Subsidiary of the Company to, (i) declare or pay any dividends or distributions
on, or redeem, purchase, acquire or make a liquidation payment with respect to,
any of the Company's capital stock (which includes common and preferred stock),
or (ii) make any payment of principal of or interest or premium, if any, on or 
repay, repurchase or redeem any debt security of the Company (including 
Securities issued by the Company pursuant to the Indenture other than the 
Securities represented by this certificate) that ranks PARI PASSU with or 
junior in interest to this Security, (iii) make any guarantee payments with 
respect to any guarantee by the Company of the debt securities of any 
Subsidiaries of the Company (if such guarantee ranks PARI PASSU in all respects
with or junior in interest to this Security) (other than (a) dividends or 
distributions in capital stock of the Company (which includes common and 
preferred stock), (b) any declaration of a dividend in connection with the 
implementation of a stockholders' rights plan, or the issuance of stock under 
any such plan in the future or the redemption or repurchase of any such rights 
pursuant thereto, (c) payments under the SVB Guarantee related to the Preferred 
Securities issued by [NAME OF TRUST], and (d) purchases of Common Stock related 
to the issuance of Common Stock or rights under any of the Company's benefit 
plans for its directors, officers or employees) or (iv) redeem, purchase or 
acquire less than all of the Securities of this series or any of the 
Preferred Securities.  Prior to the termination of any such Extension Period, 
the Company may further extend such Extension Period, PROVIDED that such 
extension does not cause such Extension Period to exceed ___ consecutive 
interest payment periods or to extend beyond the Stated Maturity.  Upon the 
termination of any such Extension Period and upon the payment of all amounts 
then due on any Interest Payment Date, and subject to the foregoing 
limitation, the Company may elect to begin a new Extension Period. No 
interest shall be due and payable during an Extension Period except at the 
end thereof. The Company shall give the Trustee, the Property Trustee and the 
Administrative Trustees of [NAME OF TRUST] notice of its election to begin 
any Extension Period at least ___ Business Days prior to the earlier of (i) 
the date on which Distributions on the Preferred Securities would be payable 
except for the election to begin such Extension Period, or (ii) the date the 
Administrative Trustees are required to give notice to the New York Stock 
Exchange, the Nasdaq National Market or other applicable stock exchange or 
automated quotation system 


                                       20


on which the Preferred Securities are then listed or quoted or to holders of 
such Preferred Securities of the record date or (iii) the date such 
Distributions are payable, but in any event not less than ___ Business Days 
prior to such record date.  The Trustee shall give notice of the Company's 
election to begin a new Extension Period to the holders of the Preferred 
Securities.  There is no limitation on the number of times that the Company 
may elect to begin an Extension Period.] 

     Payment of the principal of (and premium, if any) and interest on this 
Security will be made at the office or agency of the Trustee or at the office 
of such paying agent or paying agents as the Company may designate from time 
to time, maintained for that purpose in the United States, in such coin or 
currency of the United States of America as at the time of payment is legal 
tender for payment of public and private debts; PROVIDED, HOWEVER, that at 
the option of the Company payment of interest may be made (i) by check mailed 
to the address of the Person entitled thereto as such address shall appear in 
the Securities Register or (ii) by transfer to an account maintained by the 
person entitled thereto, in immediately available funds, at such place and to 
such account as may be designated by the Person entitled thereto as specified 
in the Securities Register.

     The indebtedness evidenced by this Security is, to the extent provided 
in the Indenture, unsecured and will rank junior and subordinate and subject 
in right of payments to the prior payment in full of all Senior and 
Subordinated Debt, and this Security is issued subject to the provisions of 
the Indenture with respect thereto. Each Holder of this Security, by 
accepting the same, (a) agrees to and shall be bound by such provisions, (b) 
authorizes and directs the Trustee on his behalf to take such actions as may 
be necessary or appropriate to effectuate the subordination so provided and 
(c) appoints the Trustee his attorney-in-fact for any and all such purposes.  
Each Holder hereof, by his acceptance hereof, waives all notice of the 
acceptance of the subordination provisions contained herein and in the 
Indenture by each holder of Senior and Subordinated Debt, whether now 
outstanding or hereafter incurred, and waives reliance by each such holder 
upon said provisions.

     Reference is hereby made to the further provisions of this Security set 
forth on the reverse hereof, which further provisions shall for all purposes 
have the same effect as if set forth at this place.

     Unless the certificate of authentication hereon has been executed by the 
Trustee referred to on the reverse hereof by manual signature, this Security 
shall not be entitled to any benefit under the Indenture or be valid or 
obligatory for any purpose.

     IN WITNESS WHEREOF, the Company has caused this instrument to be duly 
executed under its corporate seal.

extent provided in Article XIII of the Indenture.  Upon payment (i) of the 
amount of principal so declared due and payable and (ii) of interest on any

Company and delivered to the Trustee at or prior to the delivery of the 
Officers' Certificate setting forth the terms of the series.

Section III.3.  EXECUTION, AUTHENTICATION, DELIVERY AND DATING.

     The Securities shall be executed on behalf of the Company by its 
President or one of its Vice Presidents under its corporate seal reproduced 
or impressed thereon and attested by its Secretary or one of its Assistant 
Secretaries. The signature of any of these officers on the Securities may be 
manual or facsimile. 

    Securities bearing the manual or facsimile signatures of individuals who 
were at any time the proper officers of the Company shall bind the Company, 
notwithstanding that such 

                                       28


individuals or any of them have ceased to hold such offices prior to the 
authentication and delivery of such Securities or did not hold such offices 
at the date of such Securities. At any time and from time to time after the 
execution and delivery of this Indenture, the Company may deliver Securities 
of any series executed by the Company to the Trustee for authentication, 
together with a Company Order for the authentication and delivery of such 
Securities, and the Trustee in accordance with the Company Order shall 
authenticate and deliver such Securities. If the form or terms of the 
Securities of the series have been established by or pursuant to one or more 
Board Resolutions as permitted by Sections 2.1 and 3.1, in authenticating 
such Securities, and accepting the additional responsibilities under this 
Indenture in relation to such Securities, the Trustee shall be entitled to 
receive, and (subject to Section 6.1) shall be fully protected in relying 
upon, an Opinion of Counsel stating,

          (1)  if the form of such Securities has been established by or 
     pursuant to Board Resolution as permitted by Section 2.1, that such form 
     has been established in conformity with the provisions of this Indenture;

          (2)  if the terms of such Securities have been established by or 
     pursuant to Board Resolution as permitted by Section 3.1, that such 
     terms have been established in conformity with the provisions of this 
     Indenture; and

          (3)  that such Securities, when authenticated and delivered by the 
     Trustee and issued by the Company in the manner and subject to any 
     conditions specified in such Opinion of Counsel, will constitute valid 
     and legally binding obligations of the Company enforceable in accordance 
     with their terms, subject to bankruptcy, insolvency, fraudulent 
     transfer, reorganization, moratorium and similar laws of general 
     applicability relating to or affecting creditors' rights and to general 
     equity principles.

     If such form or terms have been so established, the Trustee shall not be 
required to authenticate such Securities if the issue of such Securities 
pursuant to this Indenture will affect the Trustee's own rights, duties or 
immunities under the Securities and this Indenture or otherwise in a manner 
which is not reasonably acceptable to the Trustee.

     Notwithstanding the provisions of Section 3.1 and of the preceding 
paragraph, if all Securities of a series are not to be originally issued at 
one time, it shall not be necessary to deliver the Officers' Certificate 
otherwise required pursuant to Section 3.1 or the Company Order and Opinion 
of Counsel otherwise required pursuant to such preceding paragraph at or 
prior to the authentication of each Security of such series if such documents 
are delivered at or prior to the authentication upon original issuance of the 
first Security of such series to be issued.

     Each Security shall be dated the date of its authentication. 

     No Security shall be entitled to any benefit under this Indenture or be 
valid or obligatory for any purpose, unless there appears on such Security a 
certificate of authentication substantially 

                                       29


in the form provided for herein executed by the Trustee by the manual 
signature of one of its authorized officers, and such certificate upon any 
Security shall be conclusive evidence, and the only evidence, that such 
Security has been duly authenticated and delivered hereunder. Notwithstanding 
the foregoing, if any Security shall have been authenticated and delivered 
hereunder but never issued and sold by the Company, and the Company shall 
deliver such Security to the Trustee for cancellation as provided in Section 
3.9, for all purposes of this Indenture such Security shall be deemed never 
to have been authenticated and delivered hereunder and shall never be 
entitled to the benefits of this Indenture.

Section III.4.  TEMPORARY SECURITIES.

     Pending the preparation of definitive Securities of any series, the 
Company may execute, and upon Company Order the Trustee shall authenticate 
and deliver, temporary Securities which are printed, lithographed, 
typewritten, mimeographed or otherwise produced, in any denomination, 
substantially of the tenor of the definitive Securities of such series in 
lieu of which they are issued and with such appropriate insertions, 
omissions, substitutions and other variations as the officers executing such 
Securities may determine, as evidenced by their execution of such Securities.

     If temporary Securities of any series are issued, the Company will cause 
definitive Securities of such series to be prepared without unreasonable 
delay.  After the preparation of definitive Securities, the temporary 
Securities shall be exchangeable for definitive Securities upon surrender of 
the temporary Securities at the office or agency of the Company designated 
for that purpose without charge to the Holder.  Upon surrender for 
cancellation of any one or more temporary Securities, the Company shall 
execute and the Trustee shall authenticate and deliver in exchange therefor 
one or more definitive Securities of the same series of authorized 
denominations having the same Original Issue Date and Stated Maturity and 
having the same terms as such temporary Securities.  Until so exchanged, the 
temporary Securities of any series shall in all respects be entitled to the 
same benefits under this Indenture as definitive Securities of such series.

Section III.5.  REGISTRATION, TRANSFER AND EXCHANGE.

     The Company shall cause to be kept at the Corporate Trust Office of the 
Trustee a register in which, subject to such reasonable regulations as it may 
prescribe, the Company shall provide for the registration of Securities and 
of transfers of Securities.  Such register is herein sometimes referred to as 
the "Securities Register." The Trustee is hereby appointed "Securities 
Registrar" for the purpose of registering Securities and transfers of 
Securities as herein provided.

     Upon surrender for registration of transfer of any Security at the 
office or agency of the Company designated for that purpose the Company shall 
execute, and the Trustee shall authenticate and deliver, in the name of the 
designated transferee or transferees, one or more new Securities of the same 
series of any authorized denominations, of a like aggregate principal 

                                       30


amount, of the same Original Issue Date and Stated Maturity and having the 
same terms.

     At the option of the Holder, Securities may be exchanged for other 
Securities of the same series of any authorized denominations, of a like 
aggregate principal amount, of the same Original Issue Date and Stated 
Maturity and having the same terms, upon surrender of the Securities to be 
exchanged at such office or agency. Whenever any securities are so 
surrendered for exchange, the Company shall execute, and the Trustee shall 
authenticate and deliver, the Securities which the Holder making the exchange 
is entitled to receive.

     All Securities issued upon any transfer or exchange of Securities shall 
be the valid obligations of the Company, evidencing the same debt, and 
entitled to the same benefits under this Indenture, as the Securities 
surrendered upon such transfer or exchange.

     Every Security presented or surrendered for transfer or exchange shall 
(if so required by the Company or the Securities Registrar) be duly endorsed, 
or be accompanied by a written instrument of transfer in form satisfactory to 
the Company and the Securities Registrar, duly executed by the Holder thereof 
or his attorney duly authorized in writing.

     No service charge shall be made to a Holder for any transfer or exchange 
of Securities, but the Company may require payment of a sum sufficient to 
cover any tax or other governmental charge that may be imposed in connection 
with any transfer or exchange of Securities.

     No service charge shall be made to a Holder for any transfer or exchange 
of Securities, but the Company may require payment of a sum sufficient to 
cover any tax or other governmental charge that may be imposed in connection 
with any transfer or exchange of Securities. 

     The provisions of Clauses (a), (b), (c) and (d) below shall apply only 
to Global Securities:

          (a)  Each Global Security authenticated under this Indenture shall 
     be registered in the name of the Depositary designated for such Global 
     Security or a nominee thereof and delivered to such Depositary or a 
     nominee thereof or custodian therefor, and each such Global Security 
     shall constitute a single Security for all purposes of this Indenture.

          (b)  Notwithstanding any other provision in this Indenture, no 
     Global Security may be exchanged in whole or in part for Securities 
     registered, and no transfer of a Global Security in whole or in part may 
     be registered, in the name of any Person other than the Depositary for 
     such Global Security or a nominee thereof unless (i) such Depositary (A) 
     has notified the Company that it is unwilling or unable to continue as 
     Depositary for such Global Security or (B) has ceased to be a clearing 
     agency registered under the Exchange Act at a time when the Depositary 
     is required to be so registered to act as depositary, in each case 
     unless the Company has approved a successor Depositary 

                                       31


     within 90 days, (ii) there shall have occurred and be continuing an 
     Event of Default with respect to such Global Security, (iii) the Company 
     in its sole discretion determines that such Global Security will be so 
     exchangeable or transferable or (iv) there shall exist such 
     circumstances, if any, in addition to or in lieu of the foregoing as 
     have been specified for this purpose as contemplated by Section 3.1.

          (c)  Subject to Clause (b) above, any exchange of a Global Security 
     for other Securities may be made in whole or in part, and all Securities 
     issued in exchange for a Global Security or any portion thereof shall be 
     registered in such names as the Depositary for such Global Security 
     shall direct.

          (d)  Every Security authenticated and delivered upon registration 
     of transfer of, or in exchange for or in lieu of, a Global Security or 
     any portion thereof, whether pursuant to this Section, Section 3.4, 3.6, 
     9.6 or 11.6 or otherwise, shall be authenticated and delivered in the 
     form of, and shall be, a Global Security, unless such Security is 
     registered in the name of a Person other than the Depositary for such 
     Global Security or a nominee thereof.

     Neither the Company nor the Trustee shall be required, pursuant to the 
provisions of this Section, (i) to issue, transfer or exchange any Security 
of any series during a period beginning at the opening of business 15 days 
before the day of selection for redemption of Securities pursuant to Article 
XI and ending at the close of business on the day of mailing of notice of 
redemption or (ii) to transfer or exchange any Security so selected for 
redemption in whole or in part, except, in the case of any Security to be 
redeemed in part, any portion thereof not to be redeemed.

Section III.6.  MUTILATED, DESTROYED, LOST AND STOLEN SECURITIES.

     If any mutilated Security is surrendered to the Trustee together with 
such security or indemnity as may be required by the Company or the Trustee 
to save each of them harmless, the Company shall execute and the Trustee 
shall authenticate and deliver in exchange therefor a new Security of the 
same issue and series of like tenor and principal amount, having the same 
Original Issue Date and Stated Maturity, and bearing a number not 
contemporaneously outstanding.

     If there shall be delivered to the Company and to the Trustee (i) 
evidence to their satisfaction of the destruction, loss or theft of any 
Security, and (ii) such security or indemnity as may be required by them to 
save each of them harmless, then, in the absence of notice to the Company or 
the Trustee that such Security has been acquired by a bona fide purchaser, 
the Company shall execute and upon its request the Trustee shall authenticate 
and deliver, in lieu of any such destroyed, lost or stolen Security, a new 
Security of the same issue and series of like tenor and principal amount, 
having the same Original Issue Date and Stated Maturity as such destroyed, 
lost or stolen Security, and bearing a number not contemporaneously 
outstanding.

     In case any such mutilated, destroyed, lost or stolen Security has 
become or is about to 

                                       32


become due and payable, the Company in its discretion may, instead of issuing 
a new Security, pay such Security.

     Upon the issuance of any new Security under this Section, the Company 
may require the payment of a sum sufficient to cover any tax or other 
governmental charge that may be imposed in relation thereto and any other 
expenses (including the fees and expenses of the Trustee) connected therewith.

     Every new Security issued pursuant to this Section in lieu of any 
destroyed, lost or stolen Security shall constitute an original additional 
contractual obligation of the Company, whether or not the destroyed, lost or 
stolen Security shall be at any time enforceable by anyone, and shall be 
entitled to all the benefits of this Indenture equally and proportionately 
with any and all other Securities duly issued hereunder.

     The provisions of this Section 3.6 are exclusive and shall preclude (to 
the extent lawful) all other rights and remedies with respect to the 
replacement or payment of mutilated, destroyed, lost or stolen Securities.

Section III.7.  PAYMENT OF INTEREST; INTEREST RIGHTS PRESERVED.

     Interest on any Security of any series which is payable, and is 
punctually paid or duly provided for, on any Interest Payment Date, shall be 
paid to the Person in whose name that Security (or one or more Predecessor 
Securities) is registered at the close of business on the Regular Record Date 
for such interest in respect of Securities of such series, except that, 
unless otherwise provided in the Securities of such series, interest payable 
on the Stated Maturity of the principal of a Security shall be paid to the 
Person to whom principal is paid.  The initial payment of interest on any 
Security of any series which is issued between a Regular Record Date and the 
related Interest Payment Date shall be payable as provided in such Security 
or in the Board Resolution pursuant to Section 3.1 with respect to the 
related series of Securities.

     Any interest on any Security which is payable, but is not timely paid or 
duly provided for, on any Interest Payment Date for Securities of such series 
(herein called "Defaulted Interest"), shall forthwith cease to be payable to 
the registered Holder on the relevant Regular Record Date by virtue of having 
been such Holder, and such Defaulted Interest may be paid by the Company, at 
its election in each case, as provided in Clause (a) or (b) below:

     (a)  The Company may elect to make payment of any Defaulted Interest to 
the Persons in whose names the Securities of such series in respect of which 
interest is in default (or their respective Predecessor Securities) are 
registered at the close of business on a Special Record Date for the payment 
of such Defaulted Interest, which shall be fixed in the following manner.  
The Company shall notify the Trustee in writing of the amount of Defaulted 
Interest proposed to be paid on each Security and the date of the proposed 
payment, and at the same time the Company shall deposit with the Trustee an 
amount of money equal to the aggregate amount 

                                       33


proposed to be paid in respect of such Defaulted Interest or shall make 
arrangements satisfactory to the Trustee for such deposit prior to the date 
of the proposed payment, such money when deposited to be held in trust for 
the benefit of the Persons entitled to such Defaulted Interest as in this 
Clause provided.  Thereupon, the Trustee shall fix a Special Record Date for 
the payment of such Defaulted Interest which shall be not more than 15 days 
and not less than 10 days prior to the date of the proposed payment and not 
less than 10 days after the receipt by the Trustee of the notice of the 
proposed payment.  The Trustee shall promptly notify the Company of such 
Special Record Date and, in the name and at the expense of the Company, shall 
cause notice of the proposed payment of such Defaulted Interest and the 
Special Record Date therefor to be mailed, first class, postage prepaid, to 
each Holder of a Security of such series at the address of such Holder as it 
appears in the Securities Register not less than 10 days prior to such 
Special Record Date.  The Trustee may, in its discretion, in the name and at 
the expense of the Company, cause a similar notice to be published at least 
once in a newspaper, customarily published in the English language on each 
Business Day and of general circulation in the state of California, but such 
publication shall not be a condition precedent to the establishment of such 
Special Record Date.  Notice of the proposed payment of such Defaulted 
Interest and the Special Record Date therefor having been mailed as 
aforesaid, such Defaulted Interest shall be paid to the Persons in whose 
names the Securities of such series (or their respective Predecessor 
Securities) are registered on such Special Record Date and shall no longer be 
payable pursuant to the following Clause (b).

     (b)  The Company may make payment of any Defaulted Interest in any other 
lawful manner not inconsistent with the requirements of any securities 
exchange on which the Securities of the series in respect of which interest 
is in default may be listed and, upon such notice as may be required by such 
exchange (or by the Trustee if the Securities are not listed), if, after 
notice given by the Company to the Trustee of the proposed payment pursuant 
to this Clause, such payment shall be deemed practicable by the Trustee.

     Subject to the foregoing provisions of this Section 3.7, each Security 
delivered under this Indenture upon transfer of or in exchange for or in lieu 
of any other Security shall carry the rights to interest accrued and unpaid, 
and to accrue, which were carried by such other Security.

Section III.8.  PERSONS DEEMED OWNERS.

     The Company, the Trustee and any agent of the Company or the Trustee may 
treat the Person in whose name any Security is registered as the owner of 
such Security for the purpose of receiving payment of principal of and 
(subject to Section 3.7) any interest on such Security and for all other 
purposes whatsoever, whether or not such Security be overdue, and neither the 
Company, the Trustee nor any agent of the Company or the Trustee shall be 
affected by notice to the contrary.

Section III.9.  CANCELLATION.

     All Securities surrendered for payment, redemption, transfer or exchange 
shall, if 

                                       34


surrendered to any Person other than the Trustee, be delivered to the 
Trustee, and any such Securities and Securities surrendered directly to the 
Trustee for any such purpose shall be promptly canceled by it.  The Company 
may at any time deliver to the Trustee for cancellation any Securities 
previously authenticated and delivered hereunder which the Company may have 
acquired in any manner whatsoever, and all Securities so delivered shall be 
promptly canceled by the Trustee.  No Securities shall be authenticated in 
lieu of or in exchange for any Securities canceled as provided in this 
Section, except as expressly permitted by this Indenture.  All canceled 
Securities shall be destroyed by the Trustee and the Trustee shall deliver to 
the Company a certificate of such destruction.

Section III.10.  COMPUTATION OF INTEREST.

     Except as otherwise specified as contemplated by Section 3.1 for 
Securities of any series, interest on the Securities of each series for any 
period shall be computed on the basis of a 360-day year of twelve 30-day 
months and interest on the Securities of each series for any partial period 
shall be computed on the basis of the number of days elapsed in a 360-day 
year of twelve 30-day months.

Section III.11.  DEFERRALS OF INTEREST PAYMENT DATES.

     If specified as contemplated by Section 2.1 or Section 3.1 with respect 
to the Securities of a particular series, so long as no Event of Default has 
occurred and is continuing, the Company shall have the right, at any time 
during the term of such series, from time to time to defer the payment of 
interest on such Securities for such period or periods as may be specified as 
contemplated by Section 3.1 (each, an "EXTENSION PERIOD").  During Extension 
Periods the Company shall have the right to make partial payments of interest 
on any Interest Payment Date. No Extension Period shall end on a date other 
than an Interest Payment Date. At the end of any such Extension Period, the 
Company shall pay all interest then accrued and unpaid on the Securities 
(together with Additional Interest thereon, if any, at the rate specified for 
the Securities of such series to the extent permitted by applicable law); 
PROVIDED, HOWEVER, that no Extension Period shall extend beyond the Stated 
Maturity of the principal of the Securities of such series; PROVIDED, 
FURTHER, that during any such Extension Period, the Company shall not, and 
shall not permit any Subsidiary to, (i) declare or pay any dividends or 
distributions on, or redeem, purchase, acquire or make a liquidation payment 
with respect to, any of the Company's capital stock (which includes common 
and preferred stock), (ii) make any payment of principal of or interest or 
premium, if any, on or repay, repurchase or redeem any debt securities of the 
Company (including Securities other than the Securities of such series) that 
ranks PARI PASSU in all respects with or junior in interest to the Securities 
of such series or (iii) make any guarantee payments with respect to any 
guarantee by the Company of the debt securities of any Subsidiary of the 
Company if such guarantee ranks PARI PASSU with or junior in interest to the 
Securities of such series (other than (a) dividends or distributions in 
capital stock of the Company (which includes common and preferred stock), (b) 
any declaration of a dividend in connection with the implementation of a 
stockholders' rights plan, or the issuance of stock under any such plan in 
the 

                                       35


future, or the redemption or repurchase of any such rights pursuant thereto, 
(c) payments under the SVB Guarantee related to the Preferred Securities 
issued by the SVB Trust holding Securities of such series, and (d) purchases 
of Common Stock related to the issuance of Common Stock or rights under any 
of the Company's benefit plans for its directors, officers or employees) or 
(iii) redeem, purchase or acquire less than all of the Securities of such 
series or any of the Preferred Securities.  Prior to the termination of any 
such Extension Period, the Company may further extend such Extension Period, 
PROVIDED that such extension does not cause such Extension Period to extend 
beyond the Stated Maturity of the principal of such Securities. Upon 
termination of any Extension Period and upon the payment of all accrued and 
unpaid interest and any Additional Interest then due on any Interest Payment 
Date, the Company may elect to begin a new Extension Period, subject to the 
above requirements. No interest shall be due and payable during an Extension 
Period, except at the end thereof. The Company shall give the Trustee, the 
Property Trustee and the Administrative Trustees of the SVB Trust holding 
Securities of such series notice of its election of any Extension Period (or 
an extension thereof) at least one Business Day prior to the earlier of (i) 
the next succeeding date on which Distributions on the Preferred Securities 
of such SVB Trust would be payable except for the election to begin or extend 
such Extension Period or (ii) the date the Administrative Trustees are 
required to give notice to the New York Stock Exchange, the Nasdaq National 
Market or other applicable stock exchange or automated quotation system on 
which the Preferred Securities are then listed or quoted or to holders of 
such Preferred Securities of the record date or (iii) the date such 
Distributions are payable, but in any event not less than one Business Day 
prior to such record date.  The Trustee shall give notice of the Company's 
election to begin a new Extension Period to the holders of the Securities.  
There is no limitation on the number of times that the Company may elect to 
begin an Extension Period.

     The Trustee shall promptly give notice of the Company's election to 
begin any such Extension Period to the Holders of the Outstanding Securities 
of such series. 

Section III.12.  RIGHT OF SET-OFF.

     With respect to the Securities of a series issued to a SVB Trust, 
notwithstanding anything to the contrary in the Indenture, the Company shall 
have the right to set-off any payment it is otherwise required to make 
thereunder in respect of any such Security to the extent the Company has 
theretofore made, or is concurrently on the date of such payment making, a 
payment under the Guarantee Agreement relating to such Security or under 
Section 5.8 of the Indenture.

Section III.13.  AGREED TAX TREATMENT.

     Each Security issued hereunder shall provide that the Company and, by 
its acceptance of a Security or a beneficial interest therein, the Holder of, 
and any Person that acquires a beneficial interest in, such Security agree 
that for United States Federal, state and local tax purposes it is intended 
that such Security constitute indebtedness.

Section III.14.  SHORTENING OF STATED MATURITY.

     If specified as contemplated by Section 2.1 or Section 3.1 with respect 
to the Securities of a particular series, the Company shall have the right to 
shorten the Stated Maturity of the principal of the Securities of such series 
at any time to any date not earlier than the first date on which the Company 
has the right to redeem the Securities of such series.  In the event that the 
Company elects to shorten the Stated Maturity of the Junior Subordinated 
Debentures, it shall give notice to the Indenture Trustee, and the Indenture 
Trustee shall give notice of such shortening to the holders of the Securities 
no less than 60 days prior to the effectiveness thereof.

Section III.15.  CUSIP NUMBERS.

     The Company in issuing the Securities may use "CUSIP" numbers (if then 
generally in use), and, if so, the Trustee shall use "CUSIP" numbers in 
notices of redemption as a convenience to Holders; provided that any such 
notice may state that no representation is made as to the correctness of such 
numbers either as printed on the Securities or as contained in any notice of 
a redemption and that reliance may be placed only on the other identification 
numbers printed on the Securities, and any such redemption shall not be 
affected by any defect in or omission of such numbers.

                          SATISFACTION AND DISCHARGE

Section IV.1.  SATISFACTION AND DISCHARGE OF INDENTURE.

     This Indenture shall, upon Company Request, cease to be of further 
effect (except as to any surviving rights of registration of transfer or 
exchange of Securities herein expressly provided for and as otherwise 
provided in this Section 4.1) and the Trustee, on demand of and at the 
expense of the Company, shall execute proper instruments acknowledging 
satisfaction and discharge of this Indenture, when 

     (a)  either 

     (i)    all Securities theretofore authenticated and delivered (other 
than (A) Securities which have been destroyed, lost or stolen and which have 
been replaced or paid as provided in Section 3.6 and (B) Securities for whose 
payment money has theretofore been deposited in trust or segregated and held 
in trust by the Company and thereafter repaid to the Company or discharged 
from such trust, as provided in Section 10.3) have been delivered to the 
Trustee for cancellation; or 

     (ii)   all such Securities not theretofore delivered to the Trustee for 
cancellation 

                                       37


          (A)  have become due and payable, or 

          (B)  will become due and payable at their Stated Maturity within 
     one year of the date of deposit, or

          (C)  are to be called for redemption within one year under 
     arrangements satisfactory to the Trustee for the giving of notice of 
     redemption by the Trustee in the name, and at the expense, of the Company,

and the Company, in the case of Clause (ii) (A), (B) or (C) above, has 
deposited or caused to be deposited with the Trustee as trust funds in trust 
for such purpose an amount in the currency or currencies in which the 
Securities of such series are payable sufficient to pay and discharge the 
entire indebtedness on such Securities not theretofore delivered to the 
Trustee for cancellation, for principal (and premium, if any) and interest 
(including any Additional Interest) to the date of such deposit (in the case 
of Securities which have become due and payable) or to the Stated Maturity or 
Redemption Date, as the case may be; 

     (b)  the Company has paid or caused to be paid all other sums payable 
hereunder by the Company; and 

     (c)  the Company has delivered to the Trustee an Officers' Certificate 
and an Opinion of Counsel each stating that all conditions precedent herein 
provided for relating to the satisfaction and discharge of this Indenture 
have been complied with. 

Notwithstanding the satisfaction and discharge of this Indenture, the 
obligations of the Company to the Trustee under Section 6.7, the obligations 
of the Trustee to any Authenticating Agent under Section 6.14 and, if money 
shall have been deposited with the Trustee pursuant to subclause (ii) of 
clause (a) of this Section, the obligations of the Trustee under Section 4.2 
and the last paragraph of Section 10.3 shall survive. 

Section IV.2.  APPLICATION OF TRUST MONEY.

     Subject to the provisions of the last paragraph of Section 10.3, all 
money deposited with the Trustee pursuant to Section 4.1 shall be held in 
trust and applied by the Trustee, in accordance with the provisions of the 
Securities and this Indenture, to the payment, either directly or through any 
Paying Agent (including the Company acting as its own Paying Agent) as the 
Trustee may determine, to the Persons entitled thereto, of the principal (and 
premium, if any) and interest for the payment of which such money or 
obligations have been deposited with or received by the Trustee. 

                                       38


                                   ARTICLE V

                                   REMEDIES

Section V.1.  EVENTS OF DEFAULT.

     "Event of Default", wherever used herein with respect to the Securities 
of any series, means any one of the following events (whatever the reason for 
such Event of Default and whether it shall be voluntary or involuntary or be 
effected by operation of law or pursuant to any judgment, decree or order of 
any court or any order, rule or regulation of any administrative or 
governmental body):

     (a)  default in the payment of any interest upon any Security of that 
series, including any Additional Interest in respect thereof, when it becomes 
due and payable, and continuance of such default for a period of 30 days 
(subject to the deferral of any due date in the case of an Extension Period); 
or

     (b)  default in the payment of the principal of (or premium, if any, on) 
any Security of that series at its Stated Maturity, upon redemption by 
declaration or otherwise; or

     (c)  default in the performance, or breach, in any material respect, of 
any covenant of the Company in this Indenture (other than a covenant, a 
default in the performance of which is elsewhere in this Section 5.1 
specifically dealt with), and continuance of such default or breach for a 
period of 90 days after there has been given, by registered or certified 
mail, to the Company by the Trustee or to the Company and the Trustee by the 
Holders of at least 25% in principal amount of the Outstanding Securities of 
that series a written notice specifying such default or breach and requiring 
it to be remedied; or

     (d)  the entry of a decree or order by a court having jurisdiction in 
the premises adjudging the Company a bankrupt or insolvent, or approving as 
properly filed a petition seeking reorganization, arrangement, adjustment or 
composition of or in respect of the Company under any applicable Federal or 
State bankruptcy, insolvency, reorganization or other similar law, or 
appointing a receiver, liquidator, assignee, trustee, sequestrator (or other 
similar official) of the Company or of any substantial part of its property 
or ordering the winding up or liquidation of its affairs, and the continuance 
of any such decree or order unstayed and in effect for a period of 60 
consecutive days; or

     (e)  the institution by the Company of proceedings to be adjudicated a 
bankrupt or insolvent, or the consent by it to the institution of bankruptcy 
or insolvency proceedings against it, or the filing by it of a petition or 
answer or consent seeking reorganization or relief under any applicable 
Federal or State bankruptcy, insolvency, reorganization or other similar law, 
or the consent by it to the filing of any such petition or to the appointment 
of a receiver, liquidator, assignee, trustee, sequestrator (or other similar 
official) of the Company or of any substantial part 

                                       39


of its property, or the making by it of an assignment for the benefit for 
creditors, or the admission by it in writing of its inability to pay its 
debts generally as they become due and its willingness to be adjudicated a 
bankrupt, or the taking of corporate action by the Company in furtherance of 
any such action; or

     (f)  any other Event of Default provided with respect to Securities of 
that series.

Section V.2.  ACCELERATION OF MATURITY; RESCISSION AND ANNULMENT.

     If an Event of Default (other than an Event of Default specified in 
Section 5.1(d) or 5.1(e)) with respect to Securities of any series at the 
time Outstanding occurs and is continuing, then and in every such case the 
Trustee or the Holders of not less than 25% in principal amount of the 
Outstanding Securities of that series may declare the principal amount (or, 
if the Securities of that series are Discount Securities, such portion of the 
principal amount as may be specified in the terms of that series) of all the 
Securities of that series to be due and payable immediately, by a notice in 
writing to the Company (and to the Trustee if given by Holders), PROVIDED 
that, in the case of the Securities of a series issued to a SVB Trust, if, 
upon an Event of Default, the Trustee or the Holders of not less than 25% in 
principal amount of the Outstanding Securities of that series fail to declare 
the principal of all the Securities of that series to be immediately due and 
payable, the holders of at least 25% in aggregate liquidation amount of the 
corresponding series of Preferred Securities then outstanding shall have such 
right by a notice in writing to the Company and the Trustee; and upon any 
such declaration such principal amount (or specified portion thereof) of and 
the accrued interest (including any Additional Interest) on all the 
Securities of such series shall become immediately due and payable. Payment 
of principal and interest (including any Additional Interest) on such 
Securities shall remain subordinated to the extent provided in Article XIII 
notwithstanding that such amount shall become immediately due and payable as 
herein provided. If an Event of Default specified in Section 5.1(d) or 5.1(e) 
with respect to Securities of any series at the time Outstanding occurs, the 
principal amount of all the Securities of that series (or, if the Securities 
of that series are Discount Securities, such portion of the principal amount 
of such Securities as may be specified by the terms of that series) shall 
automatically, and without any declaration or other action on the part of the 
Trustee or any Holder, become immediately due and payable.

     At any time after such a declaration of acceleration with respect to 
Securities of any series has been made and before a judgment or decree for 
payment of the money due has been obtained by the Trustee as hereinafter in 
this Article provided, the Holders of a majority in principal amount of the 
Outstanding Securities of that series, by written notice to the Company and 
the Trustee, may rescind and annul such declaration and its consequences if: 

     (a)  the Company has paid or deposited with the Trustee a sum sufficient 
to pay: 

     (i)    all overdue installments of interest (including any Additional 
Interest) on all Securities of that series, 

                                       40


     (ii)   the principal of (and premium, if any, on) any Securities of that 
series which have become due otherwise than by such declaration of 
acceleration and interest thereon at the rate borne by the Securities, and 

     (iii)  all sums paid or advanced by the Trustee hereunder and the 
reasonable compensation, expenses, disbursements and advances of the Trustee, 
its agents and counsel; and 

     (b)  all Events of Default with respect to Securities of that series, 
other than the non-payment of the principal of Securities of that series 
which has become due solely by such acceleration, have been cured or waived 
as provided in Section 5.13. 

     In the case of Securities of a series issued to a SVB Trust, the holders 
of a majority in aggregate Liquidation Amount (as defined in the Trust 
Agreement under which such SVB Trust is formed) of the related series of 
Preferred Securities issued by such SVB Trust shall also have the right to 
rescind and annul such declaration and its consequences by written notice to 
the Company and the Trustee subject to the satisfaction of the conditions set 
forth in Clauses (a) and (b) above of this Section 5.2. 

     No such rescission shall affect any subsequent default or impair any 
right consequent thereon.

Section V.3.  COLLECTION OF INDEBTEDNESS AND SUITS FOR ENFORCEMENT BY TRUSTEE.

     The Company covenants that if:

     (a)  default is made in the payment of any installment of interest 
(including any Additional Interest) on any Security when such interest 
becomes due and payable and such default continues for a period of 30 days 
(subject to the deferral of any due date in the case of an Extension Period), 
or

     (b)  default is made in the payment of the principal of (and premium, if 
any, on) any Security at the Maturity thereof,

the Company will, upon demand of the Trustee, pay to the Trustee, for the 
benefit of the Holders of such Securities, the whole amount then due and 
payable on such Securities for principal, including any sinking fund payment 
or analogous obligations (and premium, if any) and interest (including any 
Additional Interest); and, in addition thereto, all amounts owing the Trustee 
under Section 6.7.

     If the Company fails to pay such amounts forthwith upon such demand, the 
Trustee, in its own name and as trustee of an express trust, may institute a 
judicial proceeding for the collection of the sums so due and unpaid, and may 
prosecute such proceeding to judgment or final decree, 

                                       41


and may enforce the same against the Company or any other obligor upon the 
Securities and collect the moneys adjudged or decreed to be payable in the 
manner provided by law out of the property of the Company or any other 
obligor upon the Securities, wherever situated. 

     If an Event of Default with respect to Securities of any series occurs 
and is continuing, the Trustee may in its discretion proceed to protect and 
enforce its rights and the rights of the Holders of Securities of such series 
by such appropriate judicial proceedings as the Trustee shall deem most 
effectual to protect and enforce any such rights, whether for the specific 
enforcement of any covenant or agreement in this Indenture or in aid of the 
exercise of any power granted herein, or to enforce any other proper remedy.

Section V.4.  TRUSTEE MAY FILE PROOFS OF CLAIM.

     In case of the pendency of any receivership, insolvency, liquidation, 
bankruptcy, reorganization, arrangement, adjustment, composition or other 
judicial proceeding relative to the Company or any other obligor upon the 
Securities or the property of the Company or of such other obligor or their 
creditors,

     (a)  the Trustee (irrespective of whether the principal of the 
Securities of any series shall then be due and payable as therein expressed 
or by declaration or otherwise and irrespective of whether the Trustee shall 
have made any demand on the Company for the payment of overdue principal (and 
premium, if any) or interest (including any Additional Interest)) shall be 
entitled and empowered, by intervention in such proceeding or otherwise,

          (i)    to file and prove a claim for the whole amount of principal 
(and premium, if any) and interest (including any Additional Interest) owing 
and unpaid in respect to the Securities and to file such other papers or 
documents as may be necessary or advisable and to take any and all actions as 
are authorized under the Trust Indenture Act in order to have the claims of 
the Holders and any predecessor to the Trustee under Section 6.7 allowed in 
any such judicial proceedings; and

          (ii)   in particular, the Trustee shall be authorized to collect 
and receive any moneys or other property payable or deliverable on any such 
claims and to distribute the same in accordance with Section 5.6; and

     (b)  any custodian, receiver, assignee, trustee, liquidator, 
sequestrator (or other similar official) in any such judicial proceeding is 
hereby authorized by each Holder to make such payments to the Trustee for 
distribution in accordance with Section 5.6, and in the event that the 
Trustee shall consent to the making of such payments directly to the Holders, 
to pay to the Trustee any amount due to it and any predecessor Trustee under 
Section 6.7.

     Nothing herein contained shall be deemed to authorize the Trustee to 
authorize or consent to or accept or adopt on behalf of any Holder any plan 
of reorganization, arrangement, adjustment or composition affecting the 
Securities or the rights of any Holder thereof, or to 

                                       42


authorize the Trustee to vote in respect of the claim of any Holder in any 
such proceeding; provided, however, that the Trustee may, on behalf of the 
Holders, vote for the election of a trustee in bankruptcy or similar official 
and be a member of a creditors' or other similar committee.

Section V.5.  TRUSTEE MAY ENFORCE CLAIM WITHOUT POSSESSION OF SECURITIES.

     All rights of action and claims under this Indenture or the Securities 
may be prosecuted and enforced by the Trustee without the possession of any 
of the Securities or the production thereof in any proceeding relating 
thereto, and any such proceeding instituted by the Trustee shall be brought 
in its own name as trustee of an express trust, and any recovery of judgment 
shall, after provision for the payment of all the amounts owing the Trustee 
and any predecessor Trustee under Section 6.7, its agents and counsel, be for 
the ratable benefit of the Holders of the Securities in respect of which such 
judgment has been recovered.

Section V.6.  APPLICATION OF MONEY COLLECTED.

     Any money or property collected or to be applied by the Trustee with 
respect to a series of Securities pursuant to this Article shall be applied 
in the following order, at the date or dates fixed by the Trustee and, in 
case of the distribution of such money or property on account of principal 
(or premium, if any) or interest (including any Additional Interest), upon 
presentation of the Securities and the notation thereon of the payment if 
only partially paid and upon surrender thereof if fully paid:

     FIRST:  To the payment of all amounts due the Trustee and any 
predecessor Trustee under Section 6.7;

     SECOND:  Subject to Article XIII, to the payment of the amounts then due 
and unpaid upon such series of Securities for principal (and premium, if any) 
and interest (including any Additional Interest), in respect of which or for 
the benefit of which such money has been collected, ratably, without 
preference or priority of any kind, according to the amounts due and payable 
on such series of Securities for principal (and premium, if any) and interest 
(including any Additional Interest), respectively; and

     THIRD:  The balance, if any, to the Person or Persons entitled thereto.

Section V.7.  LIMITATION ON SUITS.

     No Holder of any Securities of any series shall have any right to 
institute any proceeding, judicial or otherwise, with respect to this 
Indenture or for the appointment of a receiver, assignee, trustee, 
liquidator, sequestrator (or other similar official) or for any other remedy 
hereunder, unless:

                                       43


     (a)  such Holder has previously given written notice to the Trustee of a 
continuing Event of Default with respect to the Securities of that series;

     (b)  the Holders of not less than 25% in principal amount of the 
Outstanding Securities of that series shall have made written request to the 
Trustee to institute proceedings in respect of such Event of Default in its 
own name as Trustee hereunder;

     (c)  such Holder or Holders have offered to the Trustee reasonable 
indemnity against the costs, expenses and liabilities to be incurred in 
compliance with such request:

     (d)  the Trustee for 60 days after its receipt of such notice, request 
and offer of indemnity has failed to institute any such proceeding; and

     (e)  no direction inconsistent with such written request has been given 
to the Trustee during such 60-day period by the Holders of a majority in 
principal amount of the Outstanding Securities of that series;

it being understood and intended that no one or more of such Holders shall 
have any right in any manner whatever by virtue of, or by availing itself of, 
any provision of this Indenture to affect, disturb or prejudice the rights of 
any other Holders of Securities, or to obtain or to seek to obtain priority 
or preference over any other of such Holders or to enforce any right under 
this Indenture, except in the manner herein provided and for the equal and 
ratable benefit of all such Holders.

Section V.8.  UNCONDITIONAL RIGHT OF HOLDERS TO RECEIVE PRINCIPAL, PREMIUM 
              AND INTEREST; DIRECT ACTION BY HOLDERS OF PREFERRED SECURITIES.

     Notwithstanding any other provision in this Indenture, the Holder of any 
Security shall have the right which is absolute and unconditional to receive 
payment of the principal of (and premium, if any) and (subject to Section 
3.7) interest (including any Additional Interest) on such Security on the 
respective Stated Maturities expressed in such Security (or, in the case of 
redemption, on the Redemption Date) and to institute suit for the enforcement 
of any such payment, and such right shall not be impaired without the consent 
of such Holder. In the case of Securities of a series issued to a SVB Trust, 
any holder of the corresponding series of Preferred Securities issued by such 
SVB Trust shall have the right, upon the occurrence of an Event of Default 
described in Section 5.1(a) or 5.1(b), to institute a suit directly against 
the Company for enforcement of payment to such holder of principal of 
(premium, if any) and (subject to Section 3.7) interest (including any 
Additional Interest) on the Securities having a principal amount equal to the 
aggregate Liquidation Amount (as defined in the Trust Agreement under which 
such SVB Trust is formed) of such Preferred Securities of the corresponding 
series held by such holder. 

Section V.9.  RESTORATION OF RIGHTS AND REMEDIES.

     If the Trustee, any Holder or any holder of Preferred Securities has 
instituted any 

                                       44


proceeding to enforce any right or remedy under this Indenture and such 
proceeding has been discontinued or abandoned for any reason, or has been 
determined adversely to the Trustee, such Holder or such holder of Preferred 
Securities, then and in every such case the Company, the Trustee, the Holders 
and such holder of Preferred Securities shall, subject to any determination 
in such proceeding, be restored severally and respectively to their former 
positions hereunder, and thereafter all rights and remedies of the Trustee, 
the Holders and the holders of Preferred Securities shall continue as though 
no such proceeding had been instituted. 

Section V.10.  RIGHTS AND REMEDIES CUMULATIVE.

     Except as otherwise provided in the last paragraph of Section 3.6, no 
right or remedy herein conferred upon or reserved to the Trustee or to the 
Holders is intended to be exclusive of any other right or remedy, and every 
right and remedy shall, to the extent permitted by law, be cumulative and in 
addition to every other right and remedy given hereunder or now or hereafter 
existing at law or in equity or otherwise.  The assertion or employment of 
any right or remedy hereunder, or otherwise, shall not prevent the concurrent 
assertion or employment of any other appropriate right or remedy.

Section V.11.  DELAY OR OMISSION NOT WAIVER.

     No delay or omission of the Trustee, any Holder of any Security or any 
holder of any Preferred Security to exercise any right or remedy accruing 
upon any Event of Default shall impair any such right or remedy or constitute 
a waiver of any such Event of Default or an acquiescence therein. 

     Every right and remedy given by this Article or by law to the Trustee or 
to the Holders and the right and remedy given to the holders of Preferred 
Securities by Section 5.8 may be exercised from time to time, and as often as 
may be deemed expedient, by the Trustee, the Holders or the holders of 
Preferred Securities, as the case may be. 

Section V.12.  CONTROL BY HOLDERS.

     The Holders of a majority in principal amount of the Outstanding 
Securities of any series shall have the right to direct the time, method and 
place of conducting any proceeding for any remedy available to the Trustee or 
exercising any trust or power conferred on the Trustee, with respect to the 
Securities of such series, PROVIDED that: 

     (a)  such direction shall not be in conflict with any rule of law or 
with this Indenture, 

     (b)  the Trustee may take any other action deemed proper by the Trustee 
which is not inconsistent with such direction, and 

     (c)  subject to the provisions of Section 6.1, the Trustee shall have 
the right to decline 

                                       45


to follow such direction if a Responsible Officer or Officers of the Trustee 
shall, in good faith, determine that the proceeding so directed would be 
unjustly prejudicial to the Holders not joining in any such direction or 
would involve the Trustee in personal liability. 

Section V.13.  WAIVER OF PAST DEFAULTS.

     The Holders of not less than a majority in principal amount of the 
Outstanding Securities of any series and, in the case of any Securities of a 
series issued to a SVB Trust, the holders of Preferred Securities issued by 
such SVB Trust may waive any past default hereunder and its consequences with 
respect to such series except a default: 

     (1)  in the payment of the principal of (or premium, if any) or interest 
(including any Additional Interest) on any Security of such series, or 

     (2)  in respect of a covenant or provision hereof which under Article IX 
cannot be modified or amended without the consent of the Holder of each 
Outstanding Security of such series affected. 

     Any such waiver shall be deemed to be on behalf of the Holders of all 
the Securities of such series or, in the case of a waiver by holders of 
Preferred Securities issued by such SVB Trust, by all holders of Preferred 
Securities issued by such SVB Trust.

     Upon any such waiver, such default shall cease to exist, and any Event 
of Default arising therefrom shall be deemed to have been cured, for every 
purpose of this Indenture; but no such waiver shall extend to any subsequent 
or other default or impair any right consequent thereon. 

Section V.14.  UNDERTAKING FOR COSTS.

     All parties to this Indenture agree, and each Holder of any Security by 
his acceptance thereof shall be deemed to have agreed, that any court may in 
its discretion require, in any suit for the enforcement of any right or 
remedy under this Indenture, or in any suit against the Trustee for any 
action taken or omitted by it as Trustee, the filing by any party litigant in 
such suit of an undertaking to pay the costs of such suit, and that such 
court may in its discretion assess reasonable costs, including reasonable 
attorneys' fees, against any party litigant in such suit, having due regard 
to the merits and good faith of the claims or defenses made by such party 
litigant; but the provisions of this Section shall not apply to any suit 
instituted by the Trustee, to any suit instituted by any Holder, or group of 
Holders, holding in the aggregate more than 10% in principal amount of the 
Outstanding Securities of any series, or to any suit instituted by any Holder 
for the enforcement of the payment of the principal of (or premium, if any) 
or interest (including any Additional Interest) on any Security on or after 
the respective Stated Maturities expressed in such Security.

Section V.15.  WAIVER OF USURY, STAY OR EXTENSION LAWS.

                                       46


     The Company covenants (to the extent that it may lawfully do so) that it 
will not at any time insist upon, or plead, or in any manner whatsoever claim 
or take the benefit or advantage of, any usury, stay or extension law 
wherever enacted, now or at any time hereafter in force, which may affect the 
covenants or the performance of this Indenture; and the Company (to the 
extent that it may lawfully do so) hereby expressly waives all benefit or 
advantage of any such law, and covenants that it will not hinder, delay or 
impede the execution of any power herein granted to the Trustee, but will 
suffer and permit the execution of every such power as though no such law had 
been enacted.

                                   ARTICLE VI

                                  THE TRUSTEE

Section VI.1.  CERTAIN DUTIES AND RESPONSIBILITIES.

     (a)  Except during the continuance of an Event of Default;

          (A)  the Trustee undertakes to perform such duties and only such 
duties as are specifically set forth in this Indenture, and no implied 
covenants or obligations shall be read into this Indenture against the 
Trustee; and

          (B)  in the absence of bad faith on its part, the Trustee may 
conclusively rely, as to the truth of the statements and the correctness of 
the opinions expressed therein, upon certificates or opinions furnished to 
the Trustee and conforming to the requirements of this Indenture; but in the 
case of any such certificates or opinions which by any provisions hereof are 
specifically required to be furnished to the Trustee, the Trustee shall be 
under a duty to examine the same to determine whether or not they conform to 
the requirements of this Indenture.

     (b)  In case an Event of Default has occurred and is continuing, the 
Trustee shall exercise such of the rights and powers vested in it by this 
Indenture, and use the same degree of care and skill in their exercise, as a 
prudent person would exercise or use under the circumstances in the conduct 
of his own affairs.

     (c)  No provision of this Indenture shall be construed to relieve the 
Trustee from liability for its own negligent action, its own negligent 
failure to act, or its own willful misconduct except that

          (A)  this Subsection shall not be construed to limit the effect of 
Subsection (a) of this Section;

          (B)  the Trustee shall not be liable for any error of judgment made 
in good faith by a Responsible Officer, unless it shall be proved that the 
Trustee was negligent in ascertaining the pertinent facts; and

                                       47


          (C)  the Trustee shall not be liable with respect to any action 
taken or omitted to be taken by it in good faith in accordance with the 
direction of Holders pursuant to Section 5.12 relating to the time, method 
and place of conducting any proceeding for any remedy available to the 
Trustee, or exercising any trust or power conferred upon the Trustee, under 
this Indenture with respect to the Securities of such series.

     (d)  No provision of this Indenture shall require the Trustee to expend 
or risk its own funds or otherwise incur any financial liability in the 
performance of any of its duties hereunder, or in the exercise of any of its 
rights or powers, if there shall be reasonable grounds for believing that 
repayment of such funds or adequate indemnity against such risk or liability 
is not reasonably assured to it.

     (e)  Whether or not therein expressly so provided, every provision of 
this Indenture relating to the conduct or affecting the liability of or 
affording protection to the Trustee shall be subject to the provisions of 
this Section 6.1.

Section VI.2.  NOTICE OF DEFAULTS.

     Within 90 days after actual knowledge by a Responsible Officer of the 
Trustee of the occurrence of any default hereunder with respect to the 
Securities of any series, the Trustee shall transmit by mail to all Holders 
of Securities of such series, as their names and addresses appear in the 
Securities Register, notice of such default, unless such default shall have 
been cured or waived; provided, however, that, except in the case of a 
default in the payment of the principal of (or premium, if any) or interest 
(including any Additional Interest) on any Security of such series, the 
Trustee shall be protected in withholding such notice if and so long as the 
board of directors, the executive committee or a trust committee of directors 
and/or Responsible Officers of the Trustee in good faith determines that the 
withholding of such notice is in the interests of the Holders of Securities 
of such series; and PROVIDED, FURTHER, that, in the case of any default of 
the character specified in Section 5.13, no such notice to Holders of 
Securities of such series shall be given until at least 30 days after the 
occurrence thereof.  For the purpose of this Section, the term "default" 
means any event which is, or after notice or lapse of time or both would 
become, an Event of Default with respect to Securities of such series.

costs, expenses and liabilities which might be incurred by it in compliance 
with such request or direction;

     (f)  the Trustee shall not be bound to make any investigation into the

discretion may make such inquiry or investigation into such facts or matters

Trustee's certificates of authentication, shall be taken as the statements of 
the Company, and neither the Trustee nor any Authenticating Agent assumes any 
responsibility for their correctness.  The Trustee makes no representations 
as to the validity or sufficiency of this Indenture or of the Securities.  
Neither the Trustee nor any Authenticating Agent shall be accountable for the 
use or application by the Company of the Securities or the proceeds thereof.

Section VI.5.  MAY HOLD SECURITIES.

                                       49


     The Trustee, any Authenticating Agent, any Paying Agent, any Securities 
Registrar or any other agent of the Company, in its individual or any other 
capacity, may become the owner or pledgee of Securities and, subject to 
Sections 6.8 and 6.13, may otherwise deal with the Company with the same 
rights it would have if it were not Trustee, Authenticating Agent, Paying 
Agent, Securities Registrar or such other agent.

Section VI.6.  MONEY HELD IN TRUST.

     Money held by the Trustee in trust hereunder need not be segregated from 
other funds except to the extent required by law.  The Trustee shall be under 
no liability for interest on any money received by it hereunder except as 
otherwise agreed with the Company. 

Section VI.7.  COMPENSATION AND REIMBURSEMENT.

The Company agrees

     (a)  to pay to the Trustee from time to time compensation for all 
services rendered by it hereunder in such amounts as the Company and the 
Trustee shall agree from time to time (which compensation shall not be 
limited by any provision of law in regard to the compensation of a trustee of 
an express trust);

     (b)  to reimburse the Trustee upon its request for all reasonable 
expenses, disbursements and advances incurred or made by the Trustee in 
accordance with any provision of this Indenture (including the reasonable 
compensation and the expenses and disbursements of its agents and counsel), 
except any such expense, disbursement or advance as may be attributable to 
its negligence or bad faith; and

     (c)  to indemnify the Trustee for, and to hold it harmless against, any 
loss, liability or expense (including the reasonable compensation and the 
expenses and disbursements of its agents and counsel) incurred without 
negligence or bad faith, arising out of or in connection with the acceptance 
or administration of this trust or the performance of its duties hereunder, 
including the costs and expenses of defending itself against any claim or 
liability in connection with the exercise or performance of any of its powers 
or duties hereunder.  This indemnification shall survive the termination of 
this Agreement.

     To secure the Company's payment obligations in this Section 6.7, the 
Company and the Holders agree that the Trustee shall have a lien prior to the 
Securities on all money or property held or collected by the Trustee.  Such 
lien shall survive the satisfaction and discharge of this Indenture.

     When the Trustee incurs expenses or renders services after an Event of 
Default specified in Section 5.1(d) or (e) occurs, the expenses and the 
compensation for the services are intended to constitute expenses of 
administration under the Bankruptcy Reform Act of 1978 or any successor 
statute.

                                       50


Section VI.8.  DISQUALIFICATION; CONFLICTING INTERESTS.

     The Trustee for the Securities of any series issued hereunder shall be 
subject to the provisions of Section 310(b) of the Trust Indenture Act.  
Nothing herein shall prevent the Trustee from filing with the Commission the 
application referred to in the second to last paragraph of said Section 
310(b).

Section VI.9.  CORPORATE TRUSTEE REQUIRED; ELIGIBILITY.

There shall at all times be a Trustee hereunder which shall be

     (a)  a corporation organized and doing business under the laws of the 
United States of America or of any State or Territory or the District of 
Columbia, authorized under such laws to exercise corporate trust powers and 
subject to supervision or examination by Federal, State, Territorial or 
District of Columbia authority, or

     (b)  a corporation or other Person organized and doing business under 
the laws of a foreign government that is permitted to act as Trustee pursuant 
to a rule, regulation or order of the Commission, authorized under such laws 
to exercise corporate trust powers, and subject to supervision or examination 
by authority of such foreign government or a political subdivision thereof 
substantially equivalent to supervision or examination applicable to United 
States institutional trustees,

in either case having a combined capital and surplus of at least $50,000,000, 
subject to supervision or examination by Federal or State authority.  If such 
corporation publishes reports of condition at least annually, pursuant to law 
or to the requirements of the aforesaid supervising or examining authority, 
then, for the purposes of this Section 6.9, the combined capital and surplus 
of such corporation shall be deemed to be its combined capital and surplus as 
set forth in its most recent report of condition so published.  If at any 
time the Trustee shall cease to be eligible in accordance with the provisions 
of this Section 6.9, it shall resign immediately in the manner and with the 
effect hereinafter specified in this Article VI.  Neither the Company nor any 
Person directly or indirectly controlling, controlled by or under common 
control with the Company shall serve as Trustee for the Securities of any 
series issued hereunder.

Section VI.10.  RESIGNATION AND REMOVAL; APPOINTMENT OF SUCCESSOR.

     (a)  No resignation or removal of the Trustee and no appointment of a 
successor Trustee pursuant to this Article VI shall become effective until 
the acceptance of appointment by the successor Trustee under Section 6.11.

     (b)  The Trustee may resign at any time with respect to the Securities 
of one or more series by giving written notice thereof to the Company.  If an 
instrument of acceptance by a 

                                       51


successor Trustee shall not have been delivered to the Trustee within 30 days 
after the giving of such notice of resignation, the resigning Trustee may 
petition any court of competent jurisdiction for the appointment of a 
successor Trustee with respect to the Securities of such series.

     (c)  The Trustee may be removed at any time with respect to the 
Securities of any series by Act of the Holders of a majority in principal 
amount of the Outstanding Securities of such series, delivered to the Trustee 
and to the Company.

     (d)  If at any time:

     (i)    the Trustee shall fail to comply with Section 6.8 after written 
request therefor by the Company or by any Holder who has been a bona fide 
Holder of a Security for at least six months, or

     (ii)   the Trustee shall cease to be eligible under Section 6.9 and 
shall fail to resign after written request therefor by the Company or by any 
such Holder, or

     (iii)  the Trustee shall become incapable of acting or shall be adjudged 
a bankrupt or insolvent or a receiver of the Trustee or of its property shall 
be appointed or any public officer shall take charge or control of the 
Trustee or of its property or affairs for the purpose of rehabilitation, 
conservation or liquidation,

then, in any such case, (i) the Company, acting pursuant to the authority of 
a Board Resolution, may remove the Trustee with respect to all Securities, or 
(ii) subject to Section 5.14, any Holder who has been a bona fide Holder of a 
Security for at least six months may, on behalf of himself and all others 
similarly situated, petition any court of competent jurisdiction for the 
removal of the Trustee with respect to all Securities and the appointment of 
a successor Trustee or Trustees.

     (e)  If the Trustee shall resign, be removed or become incapable of 
acting, or if a vacancy shall occur in the office of Trustee for any cause 
with respect to the Securities of one or more series, the Company, by a Board 
Resolution, shall promptly appoint a successor Trustee with respect to the 
Securities of that or those series.  If, within one year after such 
resignation, removal or incapability, or the occurrence of such vacancy, a 
successor Trustee with respect to the Securities of any series shall be 
appointed by Act of the Holders of a majority in principal amount of the 
Outstanding Securities of such series delivered to the Company and the 
retiring Trustee, the successor Trustee so appointed shall, forthwith upon 
its acceptance of such appointment, become the successor Trustee with respect 
to the Securities of such series and supersede the successor Trustee 
appointed by the Company.  If no successor Trustee with respect to the 
Securities of any series shall have been so appointed by the Company or the 
Holders and accepted appointment in the manner hereinafter provided, any 
Holder who has been a bona fide Holder of a Security for at least six months 
may, subject to Section 5.14, on behalf of himself and all others similarly 
situated, petition any court of competent jurisdiction for the appointment of 
a successor Trustee with respect to the Securities of such series.

                                       52


     (f)  The Company shall give notice of each resignation and each removal 
of the Trustee with respect to the Securities of any series and each 
appointment of a successor Trustee with respect to the Securities of any 
series by mailing written notice of such event by first-class mail, postage 
prepaid, to the Holders of Securities of such series as their names and 
addresses appear in the Securities Register.  Each notice shall include the 
name of the successor Trustee with respect to the Securities of such series 
and the address of its Corporate Trust Office.

Section VI.11.  ACCEPTANCE OF APPOINTMENT BY SUCCESSOR.

     (a)  In case of the appointment hereunder of a successor Trustee with 
respect to all Securities, every such successor Trustee so appointed shall 
execute, acknowledge and deliver to the Company and to the retiring Trustee 
an instrument accepting such appointment, and thereupon the resignation or 
removal of the retiring Trustee shall become effective and such successor 
Trustee, without any further act, deed or conveyance, shall become vested 
with all the rights, powers, trusts and duties of the retiring Trustee; but, 
on the request of the Company or the successor Trustee, such retiring Trustee 
shall, upon payment of its charges, execute and deliver an instrument 
transferring to such successor Trustee all the rights, powers and trusts of 
the retiring Trustee and shall duly assign, transfer and deliver to such 
successor Trustee all property and money held by such retiring Trustee 
hereunder.

     (b)  In case of the appointment hereunder of a successor Trustee with 
respect to the Securities of one or more (but not all) series, the Company, 
the retiring Trustee and each successor Trustee with respect to the 
Securities of one or more series shall execute and deliver an indenture 
supplemental hereto wherein each successor Trustee shall accept such 
appointment and which (1) shall contain such provisions as shall be necessary 
or desirable to transfer and confirm to, and to vest in, each successor 
Trustee all the rights, powers, trusts and duties of the retiring Trustee 
with respect to the Securities of that or those series to which the 
appointment of such successor Trustee relates, (2) if the retiring Trustee is 
not retiring with respect to all Securities, shall contain such provisions as 
shall be deemed necessary or desirable to confirm that all the rights, 
powers, trusts and duties of the retiring Trustee with respect to the 
Securities of that or those series as to which the retiring Trustee is not 
retiring shall continue to be vested in the retiring Trustee, and (3) shall 
add to or change any of the provisions of this Indenture as shall be 
necessary to provide for or facilitate the administration of the trusts 
hereunder by more than one Trustee, it being understood that nothing herein 
or in such supplemental indenture shall constitute such Trustees co-trustees 
of the same trust and that each such Trustee shall be trustee of a trust or 
trusts hereunder separate and apart from any trust or trusts hereunder 
administered by any other such Trustee and upon the execution and delivery of 
such supplemental indenture the resignation or removal of the retiring 
Trustee shall become effective to the extent provided therein and each such 
successor Trustee, without any further act, deed or conveyance, shall become 
vested with all the rights, powers, trusts, and duties of the retiring 
Trustee with respect to the Securities of that or those series to which the 
appointment of such successor Trustee relates; but, on request of the Company 
or any successor Trustee, such retiring Trustee shall duly assign, transfer 
and deliver to such successor Trustee all property and money held by such 
retiring 

                                       53


Trustee hereunder with respect to the Securities of that or those series to 
which the appointment of such successor Trustee relates.

     (c)  Upon request of any such successor Trustee, the Company shall 
execute any and all instruments for more fully and certainly vesting in and 
confirming to such successor Trustee all rights, powers and trusts referred 
to in paragraph (a) or (b) of this Section 6.11, as the case may be.

     (d)  No successor Trustee shall accept its appointment unless at the 
time of such acceptance such successor Trustee shall be qualified and 
eligible under this Article VI.

Section VI.12.  MERGER, CONVERSION, CONSOLIDATION OR SUCCESSION TO BUSINESS.

     Any corporation into which the Trustee may be merged or converted or 
with which it may be consolidated, or any corporation resulting from any 
merger, conversion or consolidation to which the Trustee shall be a party, or 
any corporation succeeding to all or substantially all of the corporate trust 
business of the Trustee, shall be the successor of the Trustee hereunder, 
provided such corporation shall be otherwise qualified and eligible under 
this Article VI, without the execution or filing of any paper or any further 
act on the part of any of the parties hereto.  In case any Securities shall 
have been authenticated, but not delivered, by the Trustee then in office, 
any successor by merger, conversion or consolidation to such authenticating 
Trustee may adopt such authentication and deliver the Securities so 
authenticated, and in case any Securities shall not have been authenticated, 
any successor to the Trustee may authenticate such Securities either in the 
name of any predecessor Trustee or in the name of such successor Trustee, and 
in all cases the certificate of authentication shall have the full force 
which it is provided anywhere in the Securities or in this Indenture that the 
certificate of the Trustee shall have.

Section VI.13.  PREFERENTIAL COLLECTION OF CLAIMS AGAINST COMPANY.

     If and when the Trustee shall be or become a creditor of the Company (or 
any other obligor upon the Securities), the Trustee shall be subject to the 
provisions of the Trust Indenture Act regarding the collection of claims 
against the Company (or any such other obligor).

Section VI.14.  APPOINTMENT OF AUTHENTICATING AGENT.

     The Trustee may appoint an Authenticating Agent or Agents with respect 
to one or more series of Securities which shall be authorized to act on 
behalf of the Trustee to authenticate Securities of such series issued upon 
original issue and upon exchange, registration of transfer or partial 
redemption thereof or pursuant to Section 3.6, and Securities so 
authenticated shall be entitled to the benefits of this Indenture and shall 
be valid and obligatory for all purposes as if authenticated by the Trustee 
hereunder.  Wherever reference is made in this Indenture to the 
authentication and delivery of Securities by the Trustee or the Trustee's 
certificate of authentication, such reference shall be deemed to include 
authentication and delivery on behalf of the Trustee by an Authenticating 
Agent.  Each Authenticating Agent shall be acceptable to the 

                                       54


Company and shall at all times be a corporation organized and doing business 
under the laws of the United States of America, or of any State or Territory 
or the District of Columbia, authorized under such laws to act as 
Authenticating Agent, having a combined capital and surplus of not less than 
$50,000,000 and subject to supervision or examination by Federal or State 
authority. If such Authenticating Agent publishes reports of condition at 
least annually, pursuant to law or to the requirements of said supervising or 
examining authority, then for the purposes of this Section 6.14 the combined 
capital and surplus of such Authenticating Agent shall be deemed to be its 
combined capital and surplus as set forth in its most recent report of 
condition so published.  If at any time an Authenticating Agent shall cease 
to be eligible in accordance with the provisions of this Section 6.14, such 
Authenticating Agent shall resign immediately in the manner and with the 
effect specified in this Section 6.14.

     Any corporation into which an Authenticating Agent may be merged or 
converted or with which it may be consolidated, or any corporation resulting 
from any merger, conversion or consolidation to which such Authenticating 
Agent shall be a party, or any corporation succeeding to all or substantially 
all of the corporate trust business of an Authenticating Agent shall be the 
successor Authenticating Agent hereunder, provided such corporation shall be 
otherwise eligible under this Section, without the execution or filing of any 
paper or any further act on the part of the Trustee or the Authenticating 
Agent.

     An Authenticating Agent may resign at any time by giving written notice 
thereof to the Trustee and to the Company.  The Trustee may at any time 
terminate the agency of an Authenticating Agent by giving written notice 
thereof to such Authenticating Agent and to the Company.  Upon receiving such 
a notice of resignation or upon such a termination, or in case at any time 
such Authenticating Agent shall cease to be eligible in accordance with the 
provisions of this Section 6.14, the Trustee may appoint a successor 
Authenticating Agent which shall be acceptable to the Company and shall give 
notice of such appointment in the manner provided in Section 1.6 to all 
Holders of Securities of the series with respect to which such Authenticating 
Agent will serve.  Any successor Authenticating Agent upon acceptance of its 
appointment hereunder shall become vested with all the rights, powers and 
duties of its predecessor hereunder, with like effect as if originally named 
as an Authenticating Agent.  No successor Authenticating Agent shall be 
appointed unless eligible under the provision of this Section 6.14.

     The Trustee agrees to pay to each Authenticating Agent from time to time 
reasonable compensation for its services under this Section 6.14, and the 
Trustee shall be entitled to be reimbursed for such payments, subject to the 
provisions of Section 6.7.

     If an appointment with respect to one or more series is made pursuant to 
this Section 6.14, the Securities of such series may have endorsed thereon, 
in addition to the Trustee's certificate of authentication, an alternative 
certificate of authentication in the following form:

     This is one of the Securities referred to in the within mentioned 
Indenture.

convey, transfer or lease its properties and assets substantially as an 
entirety to any Person, and no Person 

                                       57


shall consolidate with or merge into the Company or convey, transfer or lease 
its properties and assets substantially as an entirety to the Company, unless:

     (a)  in case the Company shall consolidate with or merge into another 
Person or convey, transfer or lease its properties and assets substantially 
as an entirety to any Person, the corporation formed by such consolidation or 
into which the Company is merged or the Person which acquires by conveyance 
or transfer, or which leases, the properties and assets of the Company 
substantially as an entirety shall be a corporation, partnership or trust 
organized and existing under the laws of the United States of America or any 
State or the District of Columbia, and shall expressly assume, by an 
indenture supplemental hereto, executed and delivered to the Trustee, in form 
satisfactory to the Trustee, the due and punctual payment of the principal of 
(and premium, if any) and interest (including any Additional Interest) on all 
the Securities and the performance of every covenant of this Indenture on the 
part of the Company to be performed or observed;

     (b)  immediately after giving effect to such transaction, no Event of 
Default, and no event which, after notice or lapse of time, or both, would 
become an Event of Default, shall have happened and be continuing;

     (c)  the Company has delivered to the Trustee an Officers' Certificate 
and an Opinion of Counsel, each stating that such consolidation, merger, 
conveyance, transfer or lease and any such supplemental indenture comply with 
this Article and that all conditions precedent herein provided for relating 
to such transaction have been complied with; and the Trustee, subject to 
Section 6.1, may rely upon such Officers' Certificate and Opinion of Counsel 
as conclusive evidence that such transaction complies with this Section 8.1.

Section VIII.2.  SUCCESSOR CORPORATION SUBSTITUTED.

     Upon any consolidation or merger by the Company with or into any other 
Person, or any conveyance, transfer or lease by the Company of its properties 
and assets substantially as an entirety to any Person in accordance with 
Section 8.1, the successor corporation formed by such consolidation or into 
which the Company is merged or to which such conveyance, transfer or lease is 
made shall succeed to, and be substituted for, and may exercise every right 
and power of, the Company under this Indenture with the same effect as if 
such successor Person had been named as the Company herein; and in the event 
of any such conveyance, transfer or lease the Company shall be discharged 
from all obligations and covenants under the Indenture and the Securities and 
may be dissolved and liquidated.

     Such successor Person may cause to be signed, and may issue either in 
its own name or in the name of the Company, any or all of the Securities 
issuable hereunder which theretofore shall not have been signed by the 
Company and delivered to the Trustee; and, upon the order of such successor 
Person instead of the Company and subject to all the terms, conditions and 
limitations in this Indenture prescribed, the Trustee shall authenticate and 
shall deliver any Securities which previously shall have been signed and 
delivered by the officers of the Company to the Trustee for 

                                       58


authentication pursuant to such provisions and any Securities which such 
successor Person thereafter shall cause to be signed and delivered to the 
Trustee on its behalf for the purpose pursuant to such provisions.  All the 
Securities so issued shall in all respects have the same legal rank and 
benefit under this Indenture as the Securities theretofore or thereafter 
issued in accordance with the terms of this Indenture as though all of such 
Securities had been issued at the date of the execution hereof.

     In case of any such consolidation, merger, sale, conveyance or lease, 
such changes in phraseology and form may be made in the Securities thereafter 
to be issued as may be appropriate.

     Without the consent of any Holders, the Company, when authorized by a 
Board Resolution, and the Trustee, at any time and from time to time, may

to the Trustee, PROVIDED, HOWEVER, that the form and terms of Securities of 
any series may be established by a Board Resolution, as set forth in the 
Officers' Certificate delivered to the Trustee pursuant to Section 3.1, 
without entering into a supplemental indenture for all purposes hereunder,

with the Trustee or to surrender any right or power herein conferred upon the

or to surrender any right or power herein conferred upon the Company; or

     (e)  to add any additional Events of Default for the benefit of the 
Holders of all or any series of Securities (and if such additional Events of 
Default are to be for the benefit of less than all series of Securities, 
stating that such additional Events of Default are expressly being included 
solely for the benefit of such series); or

                                       59


     (f)  to change or eliminate any of the provisions of this Indenture, 
provided that any such change or elimination shall become effective only when 
there is no Security Outstanding of any series created prior to the execution 
of such supplemental indenture which is entitled to the benefit of such 
provision; or

     (g)  to cure any ambiguity, to correct or supplement any provision 
herein which may be defective or inconsistent with any other provision 
herein, or to make any other provisions with respect to matters or questions 
arising under this Indenture, provided that such action pursuant to this 
clause (g) shall not adversely affect the interest of the Holders of 
Securities of any series in any material respect or, in the case of the 
Securities of a series issued to a SVB Trust and for so long as any of the 
corresponding series of Preferred Securities issued by such SVB Trust shall 
remain outstanding, the holders of such Preferred Securities; or

     (h)  to evidence and provide for the acceptance of appointment hereunder 
by a successor Trustee with respect to the Securities of one or more series 
and to add to or change any of the provisions of this Indenture as shall be 
necessary to provide for or facilitate the administration of the trusts 
hereunder by more than one Trustee, pursuant to the requirements of Section 
6.11(b); or

     (i)  to comply with the requirements of the Commission in order to 
effect or maintain the qualification of this Indenture under the Trust 
Indenture Act.

     With the consent of the Holders of not less than a majority in principal 
amount of the Outstanding Securities of each series affected by such 
supplemental indenture, by Act of said Holders delivered to the Company and 
the Trustee, the Company, when authorized by a Board Resolution, and the 
Trustee may enter into an indenture or indentures supplemental hereto for the 
purpose of adding any provisions to or changing in any manner or eliminating 
any of the provisions of this Indenture or of modifying in any manner the 
rights of the Holders of Securities of such series under this Indenture; 
PROVIDED, HOWEVER, that no such supplemental indenture shall, without the 
consent of the Holder of each Outstanding Security affected thereby, 

     (a)  except to the extent permitted by Sections 3.11 or 3.14 or as 
otherwise specified as contemplated by Section 2.1 or Section 3.1 with 
respect to the deferral of the payment of interest on the Securities of any 
series or the shortening of the Stated Maturity of the Securities of any 
series, change the Stated Maturity of the principal of, or any installment of 
interest (including any Additional Interest) on, any Security, or reduce the 
principal amount thereof or the rate of interest thereon or reduce any 
premium payable upon the redemption thereof, or reduce the amount of 
principal of a Discount Security that would be due and payable upon a 
declaration of acceleration of the Maturity thereof pursuant to Section 5.2, 
or change the place of payment where, or the coin or currency in which, any 
Security or interest thereon is payable, or impair the right to institute 
suit for the enforcement of any such payment on or after the Stated Maturity 
thereof (or, in the case of redemption, on or after the Redemption Date), or 

                                       60


     (b)  reduce the percentage in principal amount of the Outstanding 
Securities of any series, the consent of whose Holders is required for any 
such supplemental indenture, or the consent of whose Holders is required for 
any waiver (of compliance with certain provisions of this Indenture or 
certain defaults hereunder and their consequences) provided for in this 
Indenture, or 

     (c)  modify any of the provisions of this Section, Section 5.13 or 
Section 10.5, except to increase any such percentage or to provide that 
certain other provisions of this Indenture cannot be modified or waived 
without the consent of the Holder of each Security affected thereby; or 

     (d)  modify the provisions in Article XIII of this Indenture with 
respect to the subordination of Outstanding Securities of any series in a 
manner adverse to the Holders thereof; PROVIDED, FURTHER, that, in the case 
of the Securities of a series issued to a SVB Trust, so long as any of the 
corresponding series of Preferred Securities issued by such SVB Trust remains 
outstanding, (i) no such amendment shall be made that adversely affects the 
holders of such Preferred Securities in any material respect, and no 
termination of this Indenture shall occur, and no waiver of any Event of 
Default or compliance with any covenant under this Indenture shall be 
effective, without the prior consent of the holders of at least a majority of 
the aggregate liquidation preference of such Preferred Securities then 
outstanding unless and until the principal (and premium, if any) of the 
Securities of such series and all accrued and, subject to Section 3.7, unpaid 
interest (including any Additional Interest) thereon have been paid in full 
and (ii) no amendment shall be made to Section 5.8 of this Indenture that

Securities of such series and all accrued and (subject to Section 3.7) unpaid 
interest (including any Additional Interest) thereon have been paid in full.

     A supplemental indenture that changes or eliminates any covenant or 
other provision of this Indenture that has expressly been included solely for 
the benefit of one or more particular series of Securities or Preferred 
Securities, or which modifies the rights of the Holders of Securities or 
holders of Preferred Securities of such series with respect to such covenant 
or other provision, shall be deemed not to affect the rights under this 
Indenture of the Holders of Securities or holders of Preferred Securities of 
any other series. 

     It shall not be necessary for any Act of Holders under this Section to 
approve the particular form of any proposed supplemental indenture, but it 
shall be sufficient if such Act shall approve the substance thereof. 

Section IX.3.  EXECUTION OF SUPPLEMENTAL INDENTURES.

     In executing or accepting the additional series of Securities created by 
any supplemental 

                                       61


indenture permitted by this Article or the modifications thereby of any 
series of Securities previously created by this Indenture, the Trustee shall 
be entitled to receive, and (subject to Section 6.1) shall be fully protected 
in relying upon, an Officers' Certificate and an Opinion of Counsel stating 
that the execution of such supplemental indenture is authorized or permitted 
by this Indenture, and that all conditions precedent have been complied with. 
 The Trustee may, but shall not be obligated to, enter into any such 
supplemental indenture which affects the Trustee's own rights, duties or 
immunities under this Indenture or otherwise.

Section IX.4.  EFFECT OF SUPPLEMENTAL INDENTURES.

     Upon the execution of any supplemental indenture under this Article IX 
or delivery to the Trustee of the Officers' Certificate pursuant to Section 
3.1 hereof (which Officers' Certificate shall have the effect of a 
supplemental indenture for all purposes hereunder), this Indenture shall be 
modified in accordance therewith, and such supplemental indenture shall form 
a part of this Indenture for all purposes; and every Holder of Securities 
theretofore or thereafter authenticated and delivered hereunder shall be 
bound thereby.

Section IX.5.  CONFORMITY WITH TRUST INDENTURE ACT.

     Every supplemental indenture executed pursuant to this Article IX and 
every Officers' Certificate delivered to the trustee pursuant to Section 3.1 
hereof shall conform to the requirements of the Trust Indenture Act as then 
in effect.

Section IX.6.  REFERENCE IN SECURITIES TO SUPPLEMENTAL INDENTURES.

     Securities authenticated and delivered after the execution of any 
supplemental indenture pursuant to this Article IX or delivery to the Trustee

Certificate shall have the effect of a supplemental indenture for all 
purposes hereunder) may, and shall if required by the Company, bear a 
notation in form approved by the Company as to any matter provided for in 
such supplemental indenture or such Officers' Certificate.  If the Company 
shall so determine, new Securities of any series so modified as to conform, 
in the opinion of the Company, to any such supplemental indenture or such 
Officers's Certificate may be prepared and executed by the Company and 
authenticated and delivered by the Trustee in exchange for Outstanding 
Securities of such series.

                                 ARTICLE X

                                 COVENANTS

Section X.1.  PAYMENT OF PRINCIPAL, PREMIUM AND INTEREST.

     The Company covenants and agrees for the benefit of each series of 
Securities that it will duly and punctually pay the principal of (and 
premium, if any) and interest on the Securities of 

                                       62


that series in accordance with the terms of such Securities and this 
Indenture.

Section X.2.  MAINTENANCE OF OFFICE OR AGENCY.

     The Company will maintain in each Place of Payment for any series of 
Securities, an office or agency where Securities of that series may be 
presented or surrendered for payment and an office or agency where Securities 
of that series may be surrendered for transfer or exchange and where notices 
and demands to or upon the Company in respect of the Securities of that 
series and this Indenture may be served.  The Company initially appoints the 
Trustee, acting through its Corporate Trust Office, as its agent for said 
purposes.  The Company will give prompt written notice to the Trustee of any 
change in the location of any such office or agency.  If at any time the 
Company shall fail to maintain such office or agency or shall fail to furnish 
the Trustee with the address thereof, such presentations, surrenders, notices 
and demands may be made or served at the Corporate Trust Office of the 
Trustee, and the Company hereby appoints the Trustee as its agent to receive 
all such presentations, surrenders, notices and demands.

     The Company may also from time to time designate one or more other 
offices or agencies where the Securities may be presented or surrendered for 
any or all of such purposes, and may from time to time rescind such 
designations; provided, however, that no such designation or rescission shall 
in any manner relieve the Company of its obligation to maintain an office or 
agency in each Place of Payment for Securities of any series for such 
purposes.  The Company will give prompt written notice to the Trustee of any 
such designation and any change in the location of any such office or agency.

Section X.3.  MONEY FOR SECURITY PAYMENTS TO BE HELD IN TRUST.

     If the Company shall at any time act as its own Paying Agent with 
respect to any series of Securities, it will, on or before each due date of 
the principal of (and premium, if any) or interest on any of the Securities 
of such series, segregate and hold in trust for the benefit of the Persons 
entitled thereto a sum sufficient to pay the principal (and premium, if any) 
or interest so becoming due until such sums shall be paid to such Persons or 
otherwise disposed of as herein provided, and will promptly notify the 
Trustee of its failure so to act.

     Whenever the Company shall have one or more Paying Agents, it will, 
prior to 10:00 a.m. New York time on each due date of the principal of or 
interest on any Securities, deposit with a Paying Agent a sum sufficient to 
pay the principal (and premium, if any) or interest so becoming due, such sum 
to be held in trust for the benefit of the Persons entitled to such principal 
and premium (if any) or interest, and (unless such Paying Agent is the 
Trustee) the Company will promptly notify the Trustee of its failure so to 
act.

     The Company will cause each Paying Agent other than the Trustee to 
execute and deliver to the Trustee an instrument in which such Paying Agent 
shall agree with the Trustee, subject to the provisions of this Section 10.3, 
that such Paying Agent will:

                                       63


     (a)  hold all sums held by it for the payment of the principal of (and 
premium, if any) or interest on Securities in trust for the benefit of the 
Persons entitled thereto until such sums shall be paid to such Persons or 
otherwise disposed of as herein provided;

     (b)  give the Trustee notice of any default by the Company (or any other 
obligor upon the Securities) in the making of any payment of principal (and 
premium, if any) or interest:

     (c)  at any time during the continuance of any such default, upon the 
written request of the Trustee, forthwith pay to the Trustee all sums so held 
in trust by such Paying Agent; and

     (d)  comply with the provisions of the Trust Indenture Act applicable to 
it as a Paying Agent.

     The Company may at any time, for the purpose of obtaining the 
satisfaction and discharge of this Indenture or for any other purpose, pay, 
or by Company Order direct any Paying Agent to pay, to the Trustee all sums 
held in trust by the Company or such Paying Agent, such sums to be held by 
the Trustee upon the same trusts as those upon which such sums were held by 
the Company or such Paying Agent; and, upon such payment by any Paying Agent 
to the Trustee, such Paying Agent shall be released from all further 
liability with respect to such money.

     Any money deposited with the Trustee or any Paying Agent, or then held 
by the Company, in trust for the payment of the principal of (and premium, if 
any) or interest on any Security and remaining unclaimed for two years after 
such principal (and premium, if any) or interest has become due and payable 
shall (unless otherwise required by mandatory provision of applicable escheat 
or abandoned or unclaimed property law) be paid on Company Request to the 
Company, or (if then held by the Company) shall (unless otherwise required by 
mandatory provision of applicable escheat or abandoned or unclaimed property 
law) be discharged from such trust; and the Holder of such Security shall 
thereafter, as an unsecured general creditor, look only to the Company for 
payment thereof, and all liability of the Trustee or such Paying Agent with 
respect to such trust money, and all liability of the Company as trustee 
thereof, shall thereupon cease; PROVIDED, HOWEVER, that the Trustee or such 
Paying Agent, before being required to make any such repayment, may at the 
expense of the Company cause to be published once, in a newspaper published 
in the English language, customarily published on each Business Day and of 
general circulation in the state of California, notice that such money 
remains unclaimed and that, after a date specified therein, which shall not 
be less than 30 days from the date of such publication, any unclaimed balance 
of such money then remaining will be repaid to the Company.

Section X.4.  STATEMENT AS TO COMPLIANCE.

     The Company shall deliver to the Trustee, within 120 days after the end 
of each calendar 

                                       64


year of the Company ending after the date hereof, an Officers' Certificate 
covering the preceding calendar year, stating whether or not to the best 
knowledge of the signers thereof the Company is in default in the 
performance, observance or fulfillment of or compliance with any of the 
terms, provisions, covenants and conditions of this Indenture, and if the 
Company shall be in default, specifying all such defaults and the nature and 
status thereof of which they may have knowledge.  For the purpose of this 
Section 10.4, compliance shall be determined without regard to any grace 
period or requirement of notice provided pursuant to the terms of this 
Indenture.

Section X.5.  WAIVER OF CERTAIN COVENANTS.

     The Company may omit in any particular instance to comply with any 
covenant or condition provided pursuant to Sections 3.1, 9.1(c), or 9.1(d) 
with respect to the Securities of any series, if before or after the time for 
such compliance the Holders of at least a majority in principal amount of the 
Outstanding Securities of such series shall, by Act of such Holders, either 
waive such compliance in such instance or generally waive compliance with 
such covenant or condition, but no such waiver shall extend to or affect such 
covenant or condition except to the extent so expressly waived, and, until 
such waiver shall become effective, the obligations of the Company in respect 
of any such covenant or condition shall remain in full force and effect.

Section X.6.  ADDITIONAL SUMS.

     In the case of the Securities of a series issued to a SVB Trust, so long 
as no Event of Default has occurred and is continuing and except as otherwise 
specified as contemplated by Section 2.1 or Section 3.1, in the event that 
(i) such SVB Trust is the Holder of all of the Outstanding Securities of such 
series, (ii) a Tax Event in respect of such SVB Trust shall have occurred and 
be continuing and (iii) the Company shall not have (A) redeemed the 
Securities of such series pursuant to Section 11.7 or (B) terminated such SVB 
Trust pursuant to Section 9.2(b) of the related Trust Agreement, the Company 
shall pay to such SVB Trust (and its permitted successors or assigns under 
the related Trust Agreement) for so long as such SVB Trust (or its permitted 
successor or assignee) is the registered holder of any Securities of such 
series, such additional amounts as may be necessary in order that the amount 
of Distributions (including any Additional Amounts (as defined in such Trust 
Agreement)) then due and payable by such SVB Trust on the related Preferred 
Securities and Common Securities that at any time remain outstanding in 
accordance with the terms thereof shall not be reduced as a result of any 
Additional Taxes (the "ADDITIONAL SUMS"). Whenever in this Indenture or the 
Securities there is a reference in any context to the payment of principal of 
or interest on the Securities, such mention shall be deemed to include 
mention of the payments of the Additional Sums provided for in this paragraph 
to the extent that, in such context, Additional Sums are, were or would be 
payable in respect thereof pursuant to the provisions of this paragraph and 
express mention of the payment of Additional Sums (if applicable) in any 
provisions hereof shall not be construed as excluding Additional Sums in 
those provisions hereof where such express mention is not made; PROVIDED, 
HOWEVER, that the deferral of the payment of interest pursuant to Section 
3.11 or the Securities shall not defer the payment of any Additional Sums 
that may be due and payable. 

                                       65


Section X.7.  ADDITIONAL COVENANTS.

     The Company covenants and agrees with each Holder of Securities of any 
series that it shall not, and it shall not permit any Subsidiary of the 
Company to, (a) declare or pay any dividends or distributions on, or redeem, 
purchase, acquire or make a liquidation payment with respect to, any shares 
of the Company's capital stock (which includes common and preferred stock), 
(b) make any payment of principal of or interest or premium, if any, on or 
repay, repurchase or redeem any debt securities of the Company (including 
Securities other than the Securities of such series) that rank PARI PASSU in 
all respects with or junior in interest to the Securities of such series or 
(c) make any guarantee payments with respect to any guarantee by the Company 
of debt securities of any Subsidiary of the Company if such guarantee ranks 
PARI PASSU with or junior in interest to the Securities (other than (i) 
dividends or distributions in capital stock of the Company (which includes 
common and preferred stock), (ii) any declaration of a dividend in connection 
with the implementation of a rights plan, or the issuance of stock under any 
such plan in the future, or the redemption or repurchase of any such rights 
pursuant thereto, (iii) payments under the SVB Guarantee related to the 
Preferred Securities issued by the SVB Trust holding Securities of such 
series, and (iv) purchases of Common Stock related to the issuance of Common 
Stock or rights under any of the Company's benefit plans for its directors, 
officers consultants or employees or (c) redeem, purchase or acquire less 
than all of the Securities of such series or any of the Preferred Securities 
if at such time (i) there shall have occurred an Event of Default with 
respect to the Securities of such series, (ii) if the Securities of such 
series are held by a SVB Trust, the Company shall be in default with respect 
to its payment of any obligations under the SVB Guarantee relating to the 
Preferred Securities issued by such SVB Trust, or (iii) the Company shall 
have given notice of its election to begin an Extension Period with respect 
to the Securities of such series as provided herein and shall not have 
rescinded such notice, or such Extension Period, or any extension thereof, 
shall be continuing. 

     The Company also covenants with each Holder of Securities of a series 
issued to a SVB Trust (i) to maintain, directly or indirectly, 100% ownership 
of the Common Securities of such SVB Trust; PROVIDED, HOWEVER, that any 
permitted successor of the Company hereunder may succeed to the Company's 
ownership of such Common Securities, (ii) not to voluntarily terminate, 
wind-up or liquidate such SVB Trust, except (a) in connection with a 
distribution of the Securities of such series to the holders of Trust 
Securities in liquidation of such SVB Trust or (b) in connection with certain 
mergers, consolidations or amalgamations permitted by the related Trust 
Agreement and (iii) to use its reasonable efforts, consistent with the terms 
and provisions of such Trust Agreement, to cause such SVB Trust to remain 
classified as a grantor trust and not an association taxable as a corporation 
for United States federal income tax purposes. 

                                  ARTICLE XI

                            REDEMPTION OF SECURITIES

                                       66


Section XI.1.  APPLICABILITY OF THIS ARTICLE.

     Redemption of Securities of any series (whether by operation of a 
sinking fund or otherwise) as permitted or required by any form of Security 
issued pursuant to this Indenture shall be made in accordance with such form 
of Security and this Article; provided, however, that if any provision of any 
such form of Security shall conflict with any provision of this Article, the 
provision of such form of Security shall govern.  Except as otherwise set 
forth in the form of Security for such series, each Security of such series 
shall be subject to partial redemption only in the amount of $25 or, in the 
case of the Securities of a series issued to a SVB Trust, $25, or integral 
multiples of $25 in excess thereof.

Section XI.2.  ELECTION TO REDEEM; NOTICE TO TRUSTEE.

     The election of the Company to redeem any Securities shall be evidenced 
by or pursuant to a Board Resolution.  In case of any redemption at the 
election of the Company of less than all of the Securities of any particular 
series and having the same terms, the Company shall, not less than 30 nor 
more than 60 days prior to the Redemption Date (unless a shorter notice shall 
be satisfactory to the Trustee), notify the Trustee of such date and of the 
principal amount of Securities of that series to be redeemed.  In the case of 
any redemption of Securities prior to the expiration of any restriction on 
such redemption provided in the terms of such Securities, the Company shall 
furnish the Trustee with an Officers' Certificate and an Opinion of Counsel 
evidencing compliance with such restriction.

Section XI.3.  SELECTION OF SECURITIES TO BE REDEEMED.

     If less than all the Securities of any series are to be redeemed (unless 
all the Securities of such series and of a specified tenor are to be redeemed 
or unless such redemption affects only a single Security), the particular 
Securities to be redeemed shall be selected not more than 60 days prior to 
the Redemption Date by the Trustee, from the Outstanding Securities of such 
series not previously called for redemption, by such method as the Trustee 
shall deem fair and appropriate and which may provide for the selection for 
redemption of a portion of the principal amount of any Security of such 
series, provided that the portion of the principal amount of any Security not 
redeemed shall be in an authorized denomination (which shall not be less than 
the minimum authorized denomination) for such Security.  If less than all the 
Securities of such series and of a specified tenor are to be redeemed (unless 
such redemption affects only a single Security), the particular Securities to 
be redeemed shall be selected not more than 60 days prior to the Redemption 
Date by the Trustee, from the Outstanding Securities of such series and 
specified tenor not previously called for redemption in accordance with the 
preceding sentence.

     The Trustee shall promptly notify the Company in writing of the 
Securities selected for partial redemption and the principal amount thereof 
to be redeemed. For all purposes of this Indenture, unless the context 
otherwise requires, all provisions relating to the redemption of Securities 
shall relate, in the case of any Security redeemed or to be redeemed only in 
part, to the 

                                       67


portion of the principal amount of such Security which has been or is to be 
redeemed.  If the Company shall so direct, Securities registered in the name 
of the Company, any Affiliate or any Subsidiary thereof shall not be included 
in the Securities selected for redemption.

Section XI.4.  NOTICE OF REDEMPTION.

     Notice of redemption shall be given by first-class mail, postage 
prepaid, mailed not later than the thirtieth day, and not earlier than the 
sixtieth day, prior to the Redemption Date, to each Holder of Securities to 
be redeemed, at the address of such Holder as it appears in the Securities 
Register.

     With respect to Securities of each series to be redeemed, each notice of 
redemption shall state:

     (a)  the Redemption Date;

     (b)  the Redemption Price;

     (c)  if less than all Outstanding Securities of such particular series 
and having the same terms are to be redeemed, the identification (and, in the 
case of partial redemption, the respective principal amounts) of the 
particular Securities to be redeemed;

     (d)  that on the Redemption Date, the Redemption Price will become due 
and payable upon each such Security or portion thereof, and that interest 
thereon, if any, shall cease to accrue on and after said date;

     (e)  the place or places where such Securities are to be surrendered for 
payment of the Redemption Price; and

     (f)  that the redemption is for a sinking fund, if such is the case.

     Notice of redemption of Securities to be redeemed at the election of the 
Company shall be given by the Company or, at the Company's request, by the 
Trustee in the name and at the expense of the Company and shall not be 
irrevocable.  The notice if mailed in the manner herein provided shall be 
conclusively presumed to have been duly given, whether or not the Holder 
receives such notice.  In any case, a failure to give such notice by mail or 
any defect in the notice to the Holder of any Security designated for 
redemption as a whole or in part shall not affect the validity of the 
proceedings for the redemption of any other Security.

Section XI.5.  DEPOSIT OF REDEMPTION PRICE.

     Prior to 12:00 noon, Eastern time on the Redemption Date specified in 
the notice of redemption given as provided in Section 11.4, the Company will 
deposit with the Trustee or with 

                                       68


one or more Paying Agents (or if the Company is acting as its own Paying 
Agent, the Company will segregate and hold in trust as provided in Section 
10.3) an amount of money sufficient to pay the Redemption Price of, and any 
accrued interest (including Additional Interest) on, all the Securities which 
are to be redeemed on that date. 

Section XI.6.  PAYMENT OF SECURITIES CALLED FOR REDEMPTION.

     If any notice of redemption has been given as provided in Section 11.4, 
the Securities or portion of Securities with respect to which such notice has 
been given shall become due and payable on the date and at the place or 
places stated in such notice at the applicable Redemption Price. On 
presentation and surrender of such Securities at a Place of Payment in said 
notice specified, the said securities or the specified portions thereof shall 
be paid and redeemed by the Company at the applicable Redemption Price, 
together with accrued interest (including any Additional Interest) to the 
Redemption Date; PROVIDED, HOWEVER, that, unless otherwise specified as 
contemplated by Section 3.1, installments of interest whose Stated Maturity 
is on or prior to the Redemption Date will be payable to the Holders of such 
Securities, or one or more Predecessor Securities, registered as such at the 
close of business on the relevant Record Dates according to their terms and 
the provisions of Section 3.7.

     Upon presentation of any Security redeemed in part only, the Company 
shall execute and the Trustee shall authenticate and deliver to the Holder 
thereof, at the expense of the Company, a new Security or Securities of the 
same series, of authorized denominations, in aggregate principal amount equal 
to the portion of the Security not redeemed so presented and having the same 
Original Issue Date, Stated Maturity and terms.  If a Global Security is so 
surrendered, such new Security will also be a new Global Security.

     If any Security called for redemption shall not be so paid upon 
surrender thereof for redemption, the principal of and premium, if any, on 
such Security shall, until paid, bear interest from the Redemption Date at 
the rate prescribed therefor in the Security.

Section XI.7.  RIGHT OF REDEMPTION OF SECURITIES INITIALLY ISSUED TO A SVB 
               TRUST.

     In the case of the Securities of a series initially issued to a SVB 
Trust, except as otherwise specified as contemplated by Section 3.1, the 
Company, at its option, may redeem such Securities (i) on or after the date 
five years after the Original Issue Date of such Securities, in whole at any 
time or in part from time to time, or (ii) upon the occurrence and during the 
continuation of a Tax Event, Investment Company Event, or Capital Treatment 
Event, at any time within 90 days following the occurrence of such Tax Event, 
Investment Company Event or Capital Treatment Event in respect of such SVB 
Trust, in whole (but not in part), in each case at a Redemption Price equal 
to 100% of the principal amount thereof.

                                  ARTICLE XII

                                       69


                                 SINKING FUNDS

Section XII.1.  APPLICABILITY OF ARTICLE.

     The provisions of this Article shall be applicable to any sinking fund 
for the retirement of Securities of any series except as otherwise specified 
as contemplated by Section 3.1 for such Securities.

     The minimum amount of any sinking fund payment provided for by the terms 
of any Securities of any series is herein referred to as a "mandatory sinking 
fund payment", and any sinking fund payment in excess of such minimum amount 
which is permitted to be made by the terms of such Securities of any series 
is herein referred to as an "optional sinking fund payment".  If provided for 
by the terms of any Securities of any series, the cash amount of any sinking 
fund payment may be subject to reduction as provided in Section 12.2.  Each 
sinking fund payment shall be applied to the redemption of Securities of any 
series as provided for by the terms of such Securities.

Section XII.2.  SATISFACTION OF SINKING FUND PAYMENTS WITH SECURITIES.

     In lieu of making all or any part of a mandatory sinking fund payment 
with respect to any Securities of a series in cash, the Company may at its 
option, at any time no more than 16 months and no less than 30 days prior to 
the date on which such sinking fund payment is due, deliver to the Trustee 
Securities of such series (together with the unmatured coupons, if any, 
appertaining thereto) theretofore purchased or otherwise acquired by the 
Company, except Securities of such series that have been redeemed through the 
application of mandatory or optional sinking fund payments pursuant to the 
terms of the Securities of such series, accompanied by a Company Order 
instructing the Trustee to credit such obligations and stating that the 
Securities of such series were originally issued by the Company by way of 
bona fide sale or other negotiation for value; provided that the Securities 
to be so credited have not been previously so credited.  The Securities to be 
so credited shall be received and credited for such purpose by the Trustee at 
the redemption price for such Securities, as specified in the Securities so 
to be redeemed, for redemption through operation of the sinking fund and the 
amount of such sinking fund payment shall be reduced accordingly.

Section XII.3.  REDEMPTION OF SECURITIES FOR SINKING FUND.

     Not less than 60 days prior to each sinking fund payment date for any 
series of Securities, the Company will deliver to the Trustee an Officers' 
Certificate specifying the amount of the next ensuing sinking fund payment 
for such Securities pursuant to the terms of such Securities, the portion 
thereof, if any, which is to be satisfied by payment of cash in the currency 
in which the Securities of such series are payable (except as provided 
pursuant to Section 3.1) and the portion thereof, if any, which is to be 
satisfied by delivering and crediting Securities pursuant to Section 12.2 and 
will also deliver to the Trustee any Securities to be so delivered.  Such 
Officers' 

                                       70


Certificate shall be irrevocable and upon its delivery the Company shall be 
obligated to make the cash payment or payments therein referred to, if any, 
on or before the succeeding sinking fund payment date.  In the case of the 
failure of the Company to deliver such Officers' Certificate (or, as required 
by this Indenture, the Securities and coupons, if any, specified in such 
Officers' Certificate), the sinking fund payment due on the succeeding 
sinking fund payment date for such series shall be paid entirely in cash and 
shall be sufficient to redeem the principal amount of the Securities of such 
series subject to a mandatory sinking fund payment without the right to 
deliver or credit securities as provided in Section 12.2 and without the 
right to make the optional sinking fund payment with respect to such series 
at such time.

     Any sinking fund payment or payments (mandatory or optional) made in 
cash plus any unused balance of any preceding sinking fund payments made with 
respect to the Securities of any particular series shall be applied by the 
Trustee (or by the Company if the Company is acting as its own Paying Agent) 
on the sinking fund payment date on which such payment is made (or, if such 
payment is made before a sinking fund payment date, on the sinking fund 
payment date immediately following the date of such payment) to the 
redemption of Securities of such series at the Redemption Price specified in 
such Securities with respect to the sinking fund. Any sinking fund moneys not 
so applied or allocated by the Trustee (or, if the Company is acting as its 
own Paying Agent, segregated and held in trust by the Company as provided in 
Section 10.3) for such series and together with such payment (or such amount 
so segregated) shall be applied in accordance with the provisions of this 
Section 12.3.  Any and all sinking fund moneys with respect to the Securities 
of any particular series held by the Trustee (or if the Company is acting as 
its own Paying Agent, segregated and held in trust as provided in Section 
10.3) on the last sinking fund payment date with respect to Securities of 
such series and not held for the payment or redemption of particular 
Securities of such series shall be applied by the Trustee (or by the Company 
if the Company is acting as its own Paying Agent), together with other 
moneys, if necessary, to be deposited (or segregated) sufficient for the 
purpose, to the payment of the principal of the Securities of such series at 
Maturity.  The Trustee shall select the Securities to be redeemed upon such 
sinking fund payment date in the manner specified in Section 11.3 and cause 
notice of the redemption thereof to be given in the name of and at the 
expense of the Company in the manner provided in Section 11.4.  Such notice 
having been duly given, the redemption of such Securities shall be made upon 
the terms and in the manner stated in Section 11.6.  On or before each 
sinking fund payment date, the Company shall pay to the Trustee (or, if the 
Company is acting as its own Paying Agent, the Company shall segregate and 
hold in trust as provided in Section 10.3) in cash a sum in the currency in 
which Securities of such series are payable (except as provided pursuant to 
Section 3.1) equal to the principal and any interest accrued to the 
Redemption Date for Securities or portions thereof to be redeemed on such 
sinking fund payment date pursuant to this Section 12.3.

     Neither the Trustee nor the Company shall redeem any Securities of a 
series with sinking fund moneys or mail any notice of redemption of 
Securities of such series by operation of the sinking fund for such series 
during the continuance of a default in payment of interest, if any, on any 
Securities of such series or of any Event of Default (other than an Event of 
Default occurring 

                                       71


as a consequence of this paragraph) with respect to the Securities of such 
series, except that if the notice of redemption shall have been provided in 
accordance with the provisions hereof, the Trustee (or the Company, if the 
Company is then acting as its own Paying Agent) shall redeem such Securities 
if cash sufficient for that purpose shall be deposited with the Trustee (or 
segregated by the Company) for that purpose in accordance with the terms of 
this Article XII.  Except as aforesaid, any moneys in the sinking fund for 
such series at the time when any such default or Event of Default shall occur 
and any moneys thereafter paid into such sinking fund shall, during the 
continuance of such default or Event of Default, be held as security for the 
payment of the Securities and coupons, if any, of such series; provided, 
however, that in case such default or Event of Default shall have been cured 
or waived herein, such moneys shall thereafter be applied on the next sinking 
fund payment date for the Securities of such series on which such moneys may 
be applied pursuant to the provisions of this Section 12.3.

                                 ARTICLE XIII

                         SUBORDINATION OF SECURITIES

Section XIII.1.  SECURITIES SUBORDINATE TO SENIOR AND SUBORDINATED DEBT.

     The Company covenants and agrees, and each Holder of a Security, by its 
acceptance thereof, likewise covenants and agrees, that, to the extent and in 
the manner hereinafter set forth in this Article XIII, the payment of the 
principal of (and premium, if any) and interest (including any Additional 
Interest) on each and all of the Securities are hereby expressly made 
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.

Section XIII.2.  PAYMENT OVER OF PROCEEDS UPON DISSOLUTION, ETC.

     In the event of any liquidation, dissolution, winding up, receivership, 
insolvency, bankruptcy, reorganization, arrangement, adjustment, composition, 
assignment for the benefit of creditors, marshaling of assets, debt 
restructuring or other similar proceedings relative to the Company (each such 
event, if any, herein sometimes referred to as a "Proceeding"), then the 
holders of Senior and Subordinated Debt shall be entitled to receive payment 
in full of Allocable Amounts of such Senior and Subordinated Debt, or 
provision shall be made for such payment in cash or cash equivalents or 
otherwise in a manner satisfactory to the holders of Senior and Subordinated 
Debt, before the Holders of the Securities are entitled to receive or retain 
any payment or distribution of any kind or character, whether in cash, 
property or securities (including any payment or distribution which may be 
payable or deliverable by reason of the payment of any other Debt of the 
Company subordinated to the payment of the Securities, such payment or 
distribution being hereinafter referred to as a "Junior Subordinated 
Payment"), on account of principal of (or premium, if any) or interest 
(including any Additional Interest) on the Securities or on account of the 
purchase or other acquisition of Securities by the Company or any Subsidiary 
and to that end the holders of Senior and Subordinated Debt shall be entitled 
to 

                                       72


receive, for application to the payment thereof, any payment or distribution 
of any kind or character, whether in cash, property or securities, including 
any Junior Subordinated Payment, which may be payable or deliverable in 
respect of the Securities in any such Proceeding.

     In the event that, notwithstanding the foregoing provisions of this 
Section 13.2, the Trustee or the Holder of any Security shall have received 
any payment or distribution of assets of the Company of any kind or 
character, whether in cash, property or securities, including any Junior 
Subordinated Payment, before all Allocable Amounts of all Senior and 
Subordinated Debt are paid in full or payment thereof is provided for in cash 
or cash equivalents or otherwise in a manner satisfactory to the holders of 
Senior and Subordinated Debt, and if such fact shall, at or prior to the time 
of such payment or distribution, have been made known to the Trustee or, as 
the case may be, such Holder, then and in such event such payment or 
distribution shall be paid over or delivered forthwith to the trustee in 
bankruptcy, receiver, liquidating trustee, custodian, assignee, agent or 
other Person making payment or distribution of assets of the Company for 
application to the payment of all Allocable Amounts of all Senior and 
Subordinated Debt remaining unpaid, to the extent necessary to pay all 
Allocable Amounts of all Senior and Subordinated Debt in full, after giving 
effect to any concurrent payment or distribution to or for the holders of 
Senior and Subordinated Debt.

     For purposes of this Article XIII only, the words "any payment or 
distribution of any kind or character, whether in cash, property or 
securities" shall not be deemed to include shares of stock of the Company as 
reorganized or readjusted, or securities of the Company or any other 
corporation provided for by a plan of reorganization or readjustment which 
securities are subordinated in right of payment to all then outstanding 
Senior and Subordinated Debt to substantially the same extent as the 
Securities are so subordinated as provided in this Article XIII. The 
consolidation of the Company with, or the merger of the Company into, another 
Person or the liquidation or dissolution of the Company following the sale of 
all or substantially all of its properties and assets as an entirety to 
another Person upon the terms and conditions set forth in Article VIII shall 
not be deemed a Proceeding for the purposes of this Section 13.2 if the 
Person formed by such consolidation or into which the Company is merged or 
the Person which acquires by sale such properties and assets as an entirety, 
as the case may be, shall, as a part of such consolidation, merger, or sale 
comply with the conditions set forth in Article VIII.

Section XIII.3.  PRIOR PAYMENT TO SENIOR AND SUBORDINATED DEBT UPON 
                 ACCELERATION OF SECURITIES.

     In the event that any Securities are declared due and payable before 
their Stated Maturity, then and in such event the holders of the Senior and 
Subordinated Debt outstanding at the time such Securities so become due and 
payable shall be entitled to receive payment in full of all Allocable Amounts 
due on or in respect of such Senior and Subordinated Debt (including any 
amounts due upon acceleration), or provision shall be made for such payment 
in cash or cash equivalents or otherwise in a manner satisfactory to the 
holders of Senior and Subordinated Debt, before the Holders of the Securities 
are entitled to receive any payment or distribution of any kind or character, 
whether in cash, properties or securities (including any Junior Subordinated 

                                       73


Payment) by the Company on account of the principal of (or premium, if any) 
or interest (including any Additional Interest) on the Securities or on 
account of the purchase or other acquisition of Securities by the Company or 
any Subsidiary; PROVIDED, HOWEVER, that nothing in this Section 13.3 shall 
prevent the satisfaction of any sinking fund payment in accordance with this 
Indenture or as otherwise specified as contemplated by Section 3.1 for the 
Securities of any series by delivering and crediting pursuant to Section 12.2 
or as otherwise specified as contemplated by Section 3.1 for the Securities 
of any series Securities which have been acquired (upon redemption or 
otherwise) prior to such declaration of acceleration.

     In the event that, notwithstanding the foregoing, the Company shall make 
any payment to the Trustee or the Holder of any Security prohibited by the 
foregoing provisions of this Section 13.3, and if such fact shall, at or 
prior to the time of such payment, have been made known to the Trustee or, as 
the case may be, such Holder, then and in such event such payment shall be 
paid over and delivered forthwith to the Company.

     The provisions of this Section 13.3 shall not apply to any payment with 
respect to which Section 13.2 would be applicable.

Section XIII.4.  NO PAYMENT WHEN SENIOR AND SUBORDINATED DEBT IN DEFAULT.

     (a)  In the event and during the continuation of any default in the 
payment of principal of (or premium, if any) or interest on any Senior and 
Subordinated Debt, or in the event that any event of default with respect to 
any Senior and Subordinated Debt shall have occurred and be continuing and 
shall have resulted in such Senior and Subordinated Debt becoming or being 
declared due and payable prior to the date on which it would otherwise have 
become due and payable, unless and until such event of default shall have 
been cured or waived or shall have ceased to exist and such acceleration 
shall have been rescinded or annulled, or (b) in the event any judicial 
proceeding shall be pending with respect to any such default in payment or 
such event or default, then no payment or distribution of any kind or 
character, whether in cash, properties or securities (including any Junior 
Subordinated Payment) shall be made by the Company on account of principal of 
(or premium, if any) or interest (including any Additional Interest), if any, 
on the Securities or on account of the purchase or other acquisition of 
Securities by the Company or any Subsidiary, in each case unless and until 
all Allocable Amounts of such Senior and Subordinated Debt are paid in full; 
PROVIDED, HOWEVER, that nothing in this Section 13.4 shall prevent the 
satisfaction of any sinking fund payment in accordance with this Indenture or 
as otherwise specified as contemplated by Section 3.1 for the Securities of 
any series by delivering and crediting pursuant to Section 12.2 or as 
otherwise specified as contemplated by Section 3.1 for the Securities of any 
series Securities which have been acquired (upon redemption or otherwise) 
prior to such default in payment or event of default.

     In the event that, notwithstanding the foregoing, the Company shall make 
any payment to the Trustee or the Holder of any Security prohibited by the 
foregoing provisions of this Section 13.4, and if such fact shall, at or 
prior to the time of such payment, have been made known to the 

                                       74


Trustee or, as the case may be, such Holder, then and in such event such 
payment shall be paid over and delivered forthwith to the Company. 

     The provisions of this Section 13.4 shall not apply to any payment with 
respect to which Section 13.2 would be applicable.

Section XIII.5.  PAYMENT PERMITTED IF NO DEFAULT.

     Nothing contained in this Article XIII or elsewhere in this Indenture or 
in any of the Securities shall prevent (a) the Company, at any time except 
during the pendency of any Proceeding referred to in Section 13.2 or under 
the conditions described in Sections 13.3 and 13.4, from making payments at 
any time of principal of (and premium, if any) or interest (including 
Additional Interest) on the Securities, or (b) the application by the Trustee 
of any money deposited with it hereunder to the payment of or on account of 
the principal of (and premium, if any) or interest (including any Additional 
Interest) on the Securities or the retention of such payment by the Holders, 
if, at the time of such application by the Trustee, it did not have knowledge 
that such payment would have been prohibited by the provisions of this 
Article XIII.

Section XIII.6.  SUBROGATION TO RIGHTS OF HOLDERS OF SENIOR AND SUBORDINATED 
                 DEBT.

     Subject to the payment in full of all amounts due or to become due on 
all Senior and Subordinated Debt, or the provision for such payment in cash 
or cash equivalents or otherwise in a manner satisfactory to the holders of 
Senior and Subordinated Debt, the Holders of the Securities shall be 
subrogated to the extent of the payments or distributions made to the holders 
of such Senior and Subordinated Debt pursuant to the provisions of this 
Article XIII (equally and ratably with the holders of all indebtedness of the 
Company which by its express terms is subordinated to Senior and Subordinated 
Debt of the Company to substantially the same extent as the Securities are 
subordinated to the Senior and Subordinated Debt and is entitled to like 
rights of subrogation by reason of any payments or distributions made to 
holders of such Senior and Subordinated Debt) to the rights of the holders of 
such Senior and Subordinated Debt to receive payments and distributions of 
cash, property and securities applicable to the Senior and Subordinated Debt 
until the principal of (and premium, if any) and interest on the Securities 
shall be paid in full.  For purposes of such subrogation, no payments or 
distributions to the holders of the Senior and Subordinated Debt of any cash, 
property or securities to which the Holders of the Securities or the Trustee 
would be entitled except for the provisions of this Article, and no payments 
pursuant to the provisions of this Article XIII to the holders of Senior and 
Subordinated Debt by Holders of the Securities or the Trustee shall, as among 
the Company, its creditors other than holders of Senior and Subordinated 
Debt, and the Holders of the Securities, be deemed to be a payment or 
distribution by the Company to or on account of the Senior and Subordinated 
Debt.

Section XIII.7.  PROVISIONS SOLELY TO DEFINE RELATIVE RIGHTS.

     The provisions of this Article XIII are and are intended solely for the 
purpose of defining 

                                       75


the relative rights of the Holders of the Securities on the one hand and the 
holders of Senior and Subordinated Debt on the other hand.  Nothing contained 
in this Article XIII or elsewhere in this Indenture or in the Securities is 
intended to or shall (a) impair, as between the Company and the Holders of 
the Securities, the obligations of the Company, which are absolute and 
unconditional, to pay to the Holders of the Securities the principal of (and 
premium, if any) and interest (including any Additional Interest) on the 
Securities as and when the same shall become due and payable in accordance 
with their terms; or (b) affect the relative rights against the Company of 
the Holders of the Securities and creditors of the Company other than their 
rights in relation to the holders of Senior and Subordinated Debt; or (c) 
prevent the Trustee or the Holder of any Security from exercising all 
remedies otherwise permitted by applicable law upon default under this 
Indenture including, without limitation, filing and voting claims in any 
Proceeding, subject to the rights, if any, under this Article XIII of the 
holders of Senior and Subordinated Debt to receive cash, property and 
securities otherwise payable or deliverable to the Trustee or such Holder.

Section XIII.8.  TRUSTEE TO EFFECTUATE SUBORDINATION.

     Each Holder of a Security by his or her acceptance thereof authorizes 
and directs the Trustee on his or her behalf to take such action as may be 
necessary or appropriate to acknowledge or effectuate the subordination 
provided in this Article XIII and appoints the Trustee his or her 
attorney-in-fact for any and all such purposes.

Section XIII.9.  NO WAIVER OF SUBORDINATION PROVISIONS.

     No right of any present or future holder of any Senior and Subordinated 
Debt to enforce subordination as herein provided shall at any time in any way 
be prejudiced or impaired by any act or failure to act on the part of the 
Company or by any act or failure to act, in good faith, by any such holder, 
or by any noncompliance by the Company with the terms, provisions and 
covenants of this Indenture, regardless of any knowledge thereof that any 
such holder may have or be otherwise charged with.

     Without in any way limiting the generality of the immediately preceding 
paragraph, the holders of Senior and Subordinated Debt may, at any time and 
from to time, without the consent of or notice to the Trustee or the Holders 
of the Securities, without incurring responsibility to the Holders of the 
Securities and without impairing or releasing the subordination provided in 
this Article or the obligations hereunder of the Holders of the Securities to 
the holders of Senior and Subordinated Debt, do any one or more of the 
following:  (i) change the manner, place or terms of payment or extend the 
time of payment of, or renew or alter, Senior and Subordinated Debt, or 
otherwise amend or supplement in any manner Senior and Subordinated Debt or 
any instrument evidencing the same or any agreement under which Senior and 
Subordinated Debt is outstanding; (ii) sell, exchange, release or otherwise 
deal with any property pledged, mortgaged or otherwise securing Senior and 
Subordinated Debt; (iii) release any Person liable in any manner for the 
collection of Senior and Subordinated Debt; and (iv) exercise or refrain from 
exercising any 

                                       76


rights against the Company and any other Person.

Section XIII.10.  NOTICE TO TRUSTEE.

     The Company shall give prompt written notice to the Trustee of any fact 
known to the Company which would prohibit the making of any payment to or by 
the Trustee in respect of the Securities.  Notwithstanding the provisions of 
this Article XIII or any other provision of this Indenture, the Trustee shall 
not be charged with knowledge of the existence of any facts which would 
prohibit the making of any payment to or by the Trustee in respect of the 
Securities, unless and until the Trustee shall have received written notice 
thereof from the Company or a holder of Senior and Subordinated Debt or from 
any trustee, agent or representative therefor; provided, however, that if the 
Trustee shall not have received the notice provided for in this Section 13.10 
at least two Business Days prior to the date upon which by the terms hereof 
any monies may become payable for any purpose (including, without limitation, 
the payment of the principal of (and premium, if any) or interest (including 
any Additional Interest) on any Security), then, anything herein contained to 
the contrary notwithstanding, the Trustee shall have full power and authority 
to receive such monies and to apply the same to the purpose for which they 
were received and shall not be affected by any notice to the contrary which 
may be received by it within two Business Days prior to such date.

     Subject to the provisions of Section 6.1, the Trustee shall be entitled 
to rely on the delivery to it of a written notice by a Person representing 
himself to be a holder of Senior and Subordinated Debt (or a trustee 
therefor) to establish that such notice has been given by a holder of Senior 
and Subordinated Debt (or a trustee therefor). In the event that the Trustee 
determines in good faith that further evidence is required with respect to 
the right of any Person as a holder of Senior and Subordinated Debt to 
participate in any payment or distribution pursuant to this Article, the 
Trustee may request such Person to furnish evidence to the reasonable 
satisfaction of the Trustee as to the amount of Senior and Subordinated Debt 
held by such Person, the extent to which such Person is entitled to 
participate in such payment or distribution and any other facts pertinent to 
the rights of such Person under this Article, and if such evidence is not 
furnished, the Trustee may defer any payment to such Person pending judicial 
determination as to the right of such Person to receive such payment.

Section XIII.11.  RELIANCE ON JUDICIAL ORDER OR CERTIFICATE OF LIQUIDATING 
                  AGENT.

     Upon any payment or distribution of assets of the Company referred to in 
this Article XIII, the Trustee, subject to the provisions of Section 6.1, and 
the Holders of the Securities shall be entitled to rely upon any order or 
decree entered by any court of competent jurisdiction in which such 
Proceeding is pending, or a certificate of the trustee in bankruptcy, 
receiver, liquidating trustee, custodian, assignee for the benefit of 
creditors, agent or other Person making such payment or distribution, 
delivered to the Trustee or to the Holders of Securities, for the purpose of 
ascertaining the Persons entitled to participate in such payment or 
distribution, the holders of the Senior and Subordinated Debt and other 
indebtedness of the Company, the amount 

                                       77


thereof or payable thereon, the amount or amounts paid or distributed thereon 
and all other facts pertinent thereto or to this Article XIII.

Section XIII.12.  TRUSTEE NOT FIDUCIARY FOR HOLDERS OF SENIOR AND 
                  SUBORDINATED DEBT.

     The Trustee, in its capacity as trustee under this Indenture, shall not 
be deemed to owe any fiduciary duty to the holders of Senior and Subordinated 
Debt and shall not be liable to any such holders if it shall in good faith 
mistakenly pay over or distribute to Holders of Securities or to the Company 
or to any other Person cash, property or securities to which any holders of 
Senior and Subordinated Debt shall be entitled by virtue of this Article or 
otherwise.

Section XIII.13.  RIGHTS OF TRUSTEE AS HOLDER OF SENIOR AND SUBORDINATED 
                   DEBT; PRESERVATION OF TRUSTEE'S RIGHTS.

     The Trustee in its individual capacity shall be entitled to all the 
rights set forth in this Article XIII with respect to any Senior and 
Subordinated Debt which may at any time be held by it, to the same extent as 
any other holder of Senior and Subordinated Debt, and nothing in this 
Indenture shall deprive the Trustee of any of its rights as such holder.

Section XIII.14.  ARTICLE APPLICABLE TO PAYING AGENTS.

     In case at any time any Paying Agent other than the Trustee shall have 
been appointed by the Company and be then acting hereunder, the term 
"Trustee" as used in this Article XIII shall in such case (unless the context 
otherwise requires) be construed as extending to and including such Paying 
Agent within its meaning as fully for all intents and purposes as if such 
Paying Agent were named in this Article XIII in addition to or in place of 
the Trustee.

Section XIII.15.  CERTAIN CONVERSIONS OR EXCHANGES DEEMED PAYMENT.

     For the purposes of this Article XIII only, (a) the issuance and 
delivery of junior securities upon conversion or exchange of Securities shall 
not be deemed to constitute a payment or distribution on account of the 
principal of (or premium, if any) or interest (including any Additional 
Interest) on Securities or on account of the purchase or other acquisition of 
Securities, and (b) the payment, issuance or delivery of cash, property or 
securities (other than junior securities) upon conversion or exchange of a 
Security shall be deemed to constitute payment on account of the principal of 
such security.  For the purposes of this Section 13.15, the term "junior 
securities" means (i) shares of any stock of any class of the Company and 
(ii) securities of the Company which are subordinated in right of payment to 
all Senior and Subordinated Debt which may be outstanding at the time of 
issuance or delivery of such securities to substantially the same extent as, 
or to a greater extent than, the Securities are so subordinated as provided 
in this Article XIII.
