interest or other payment in respect of any such delay. However, if such Business Day is in the next succeeding calendar year, then such installment payment shall be made on the immediately preceding Business Day, in each case with the same force
and effect as if made on such date. 
 (c)  Option To Extend Installment Payment Period. 

(i)  The Company may defer installment payments, at any time and from time to time, by extending the Installment

 (ii)  At the end of any Extension Period, the Company shall pay all installment payments for which the related
Installment Payment Date occurred during such Extension Period, together with interest on the full amount of such installment payments compounded quarterly at the rate of 7.50% per annum, to the extent permitted by applicable law. The Company
shall give holders of Units and Holders of Notes at least 10 Business Days’ notice prior to the end of an Extension Period. 

(iii)  Prior to the termination of any Extension Period, the Company may further defer installment payments by
extending such Extension Period. Such Extension Period, including all such previous and further extensions, may not extend beyond May 15, 2019. Upon the termination of any Extension Period and the payment of all amounts then due, the Company
may commence a new Extension Period, if consistent with the terms set forth in this Section 2.03(c). No installment payment (or interest thereon) shall be due and payable during an Extension Period. 

(iv)  The Company shall give the holders of Units, Holders of Notes and the Trustee notice of its election of an
Extension Period (or any extension thereof) at least 10 Business Days prior to the earlier of (x) the next succeeding Installment Payment Date; or (y) the date upon which the Company is required to give notice to Holders of Notes of the
Regular Record Date or Installment Payment Date. 
 (d)  Restrictions Applicable During an Extension Period and Certain Other
Circumstances. 
 (i)  If (x) there shall have occurred and be continuing an Event of Default or
(y) the Company shall have given notice of its election to defer installment payments on the Notes by extending the Installment Payment Period, and such Installment Payment Period, or any extension of such Installment Payment Period, shall be
continuing, then: 
 (A)  the Company and its Subsidiaries shall not declare or pay any dividend on, make any
distributions relating to, or redeem, purchase, acquire or make a liquidation payment relating to, any of the Company’s capital stock or make any guarantee payment with respect thereto other than: 

(1)  purchases, redemptions or other acquisitions of shares of capital stock of the Company in connection with any
employment contract, benefit plan or other similar arrangement with or for the benefit of employees, officers, directors or consultants; 

(2)  purchases of shares of the Company’s common stock pursuant to a contractually binding requirement to buy
stock existing prior to the commencement of the Extension Period, including under a contractually binding stock repurchase plan; 

(3)  as a result of an exchange or conversion of any class or series of the Company’s capital stock for any
other class or series of the Company’s capital stock; 
 (4)  the purchase of fractional interests in shares
of the Company’s capital stock pursuant to the conversion or exchange provisions of such capital stock or the security being converted or exchanged; or 

(5)  purchases of the Company’s capital stock in connection with the distribution thereof; and 

(B)  the Company and its Subsidiaries shall not make any payment of interest or principal on, or repay, purchase or
redeem, any unsecured debt securities or guarantees issued by the Company that rank equally with or junior to the Notes other than pro rata payments of accrued and unpaid interest on the Notes and any other unsecured debt securities or
guarantees issued by 

  
 6 








 
the Company that rank equally with the Notes, except and to the extent the terms of any such debt securities would prohibit the Company from making such pro rata payment. 

These foregoing restrictions shall not apply to any stock dividends paid by the Company where the dividend stock is the same stock as, or
junior to, that stock on which the dividend is being paid.

avoidance of doubt, the provisions of Articles Four (Satisfaction and Discharge) and Fourteen (Defeasance and Covenant Defeasance) of the Base Indenture shall apply to the Notes.

compensation, expenses, disbursements and advances of the Trustee, its agents, attorneys and counsel. If the Company does not pay such amounts upon such demand, the Trustee shall be entitled and empowered to institute any actions or proceeding at
law or in equity for the collection of the sums so due and unpaid, and may prosecute any such action or proceeding to judgment or final decree, and 

  
 7 








 
may enforce any such judgment or final decree against the Company or any other obligor on the Notes and collect in the manner provided by law out of the property of the Company or any other
obligor on the Notes, wherever situated, the money adjudged or decreed to be payable. The first two paragraphs of Section 503 of the Base Indenture will not apply to the Notes.

transfer or delivery of the Notes or Units. 
 (b)  If the Paying Agent holds money on the Repurchase Date sufficient to pay the
Repurchase Price with respect to those Notes for which the Repurchase Right has been exercised, then (i) such Notes shall cease to be outstanding and interest shall cease to accrue thereon (whether or not book-entry transfer of the Notes or
Units, as applicable, is made or whether or not the Notes or Units, as applicable, are delivered as required herein), and (ii) all other rights of the Holder shall terminate (other than the right to receive the Repurchase Price and, if the
Repurchase Date falls between a Regular Record Date and the corresponding Installment Payment Date, the related Installment Payment); provided, however, that if the Repurchase Date falls after a Regular Record Date and on or prior to the immediately
succeeding Installment Payment Date, then the Installment Payment payable on such Installment Payment Date will be paid on such Installment Payment Date to the Holder as of the close of business on such Regular Record Date and shall not be included
in the Repurchase Price per note. 
 (c)  The Company shall, in connection with any repurchase offer pursuant to this Article 9,
if required by applicable provisions of the Exchange Act or SEC regulations thereunder, (i) comply with the provisions of the tender offer rules under the Exchange Act that may then be applicable, and (ii) file a Schedule TO or any other
required schedule under the Exchange Act. 
 (d)  Notwithstanding anything to the contrary herein, no Notes may be repurchased at
the option of Holders if the principal amount thereof has been accelerated, and such acceleration has not been rescinded, on or prior to the Repurchase Date (except in the case of an acceleration resulting from a Default by the Company in the
payment of the Repurchase Price with respect to such Notes).

[        ]]2 in quarterly installment payments (each constituting a payment of interest at the rate per year of 7.50% and a partial repayment of principal)
payable on May 15, August 15, November 15 and February 15 of each year (each such date, an “Installment Payment Date” and the period from, and including, May 21, 2014 to, but excluding, the first

 [FORM OF REVERSE OF NOTE] 

BANC OF CALIFORNIA, INC. 

This Note is one of a duly authorized series of Securities of the Company designated as its “7.50% Junior Subordinated
Amortizing Notes due 2017” (herein referred to as the “Notes”), issued under the Indenture, dated as of May 21, 2014, between the Company and U.S. Bank National Association, as trustee (the “Trustee,”
which term includes any successor trustee under the Indenture) (the “Base Indenture,” and the Base Indenture, as supplemented by the First Supplemental Indenture, dated as of May 21, 2014, (the “Supplemental
Indenture”), between the Company and the Trustee, the “Indenture”), to which Indenture reference is hereby made for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the
Trustee, the Company and the Holders. The terms of other series of Securities issued under the Indenture may vary with respect to interest rates, issue dates, maturity, redemption, repayment, currency of payment and otherwise as provided in the
Indenture. This series of Securities is limited in aggregate principal amount as and to the extent specified in said First Supplemental Indenture. 

Capitalized terms used herein have the meanings assigned to them in the Indenture referred to below unless otherwise
indicated. 
 Each installment shall constitute a payment of interest (at a rate of 7.50% per annum) and a partial
repayment of principal on the Note, allocated as set forth in the schedule below: 
  

					
	Scheduled Installment Payment Date	 	      Amount of Principal      	 	      Amount of Interest      
	 August 15, 2014
	 	$0.747754	 	$0.185579
	 November 15, 2014
	 	$0.815185	 	$0.184815

	 August 15, 2015
	 	$0.861904	 	$0.138096
	 November 15, 2015
	 	$0.878065	 	$0.121935
	 February 15, 2016
	 	$0.894529	 	$0.105471

	 May 15, 2017
	 	$0.981595	 	$0.018405

 Installment payments may be deferred by the Company in accordance with the provisions of
Section 2.03(c) of the Supplemental Indenture. 
 This Note will not be subject to redemption at the option of the
Company. However, a Holder shall have the right to require the Company to repurchase some or all of its Notes for cash at the Repurchase Price per Note, and on the Repurchase Date, upon the occurrence of certain events, and subject to the conditions
set forth in the Indenture. 
 This Note is not entitled to the benefit of any sinking fund. 

The Indenture contains provisions for defeasance and covenant defeasance at any time of the indebtedness on this Note upon
compliance by the Company with certain conditions set forth therein, which provisions apply to this Note. 
 If an Event of
Default relating to specified events of bankruptcy, insolvency or reorganization, or court appointment of a receiver, liquidator or trustee of the Company occurs and is continuing, then and in each such case either the Trustee or the Holders of not
less than 25% in aggregate initial principal amount of the Notes then outstanding, by notice in writing to the Company (and to the Trustee if given by Holders), may declare the principal amount of all the Notes to be due and payable immediately, and
upon any such declaration the same shall become immediately due and payable. This provision, however, is subject to the condition that, at any time after such a 

  
 A-5 








 
declaration of acceleration, and before any judgment or decree for the payment of the money due shall have been obtained or entered, the Holders of a majority in aggregate principal amount of the
Notes then outstanding, by written notice to the Company and to the Trustee, may waive all defaults and rescind and annul such declaration and its consequences, if certain conditions are met as set forth in the Indenture. 

There is no right of acceleration upon the occurrence of an Event of Default described in Section 5.01(a) of the
Supplemental Indenture or as described in Section 501(4) of the Base Indenture. 
 In the case of the additional Event
of Default described in Section 5.01(a) of the Supplemental Indenture, then, upon demand of the Trustee, the Company will pay to the Trustee, for the benefit of the Holders of the Notes, the whole amount that then shall have become due and
payable on all such Notes for principal, premium, if any, or interest, or any combination thereof, as the case may be, with interest upon the overdue principal and (to the extent that payment of such interest is enforceable under applicable law)
upon the overdue installments of interest, at the rate borne by the Notes; and, in addition, such further amount as shall be sufficient to cover the costs and expenses of collection, including reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents, attorneys and counsel. If the Company does not pay such amounts upon such demand, the Trustee shall be entitled and empowered to institute any actions or proceeding at law or in equity for the collection of the
sums so due and unpaid, and may prosecute any such action or proceeding to judgment or final decree, and may enforce any such judgment or final decree against the Company or any other obligor on the Notes and collect in the manner provided by law
out of the property of the Company or any other obligor on the Notes, wherever situated, the money adjudged or decreed to be payable. 

The Indenture permits, with certain exceptions as therein provided, the Company and the Trustee, with the consent of the
Holders of not less than a majority in principal amount of the Securities at the time outstanding of each series issued under the Indenture to be affected thereby, to execute supplemental indentures for certain purposes as described therein. 

No provision of this Note or of the Indenture shall alter or impair the obligation of the Company, which is absolute and
unconditional, to pay installments on this Note at the time, place and rate, and in the coin or currency, herein and in the Indenture prescribed, subject to the Company’s right to defer installment payments as described therein. 

As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Note shall be
registered on the Security Register of the Company, upon surrender of this Note for registration of transfer at the office or agency of the Company in New York, New York, duly endorsed by, or accompanied by a written instrument of transfer in form
satisfactory to the Company and the Trustee duly executed by, the Holder hereof or by his attorney duly authorized in writing, and thereupon one or more new Notes of this series and of like tenor, of authorized denominations and for the same
aggregate principal amount, shall be issued to the designated transferee or transferees. 
 The Notes are initially issued
in the form of Global Notes in initial minimum denominations of one Note and integral multiples in excess thereof. 
 No
charge shall be made for any such registration of transfer or exchange, but the Company may require the payment of a sum sufficient to cover any applicable tax or other governmental charge payable in connection with the transfer. 

The Company, the Trustee and any agent of the Company or the Trustee may deem and treat the Holder in whose name any Note
shall be registered upon the Security Register for the Notes as the absolute owner of such Note (whether or not such Note shall be overdue and notwithstanding any notation of ownership or other writing thereon) for the purpose of receiving
installment payments on such Note and for all other purposes; and neither the Company nor the Trustee nor any agent of the Company or the Trustee shall be affected by any notice to the contrary. 

  
 A-6 








 THIS NOTE AND THE INDENTURE SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH
THE LAWS OF THE STATE OF NEW YORK. EACH OF THE COMPANY AND THE TRUSTEE, AND EACH HOLDER OF A SECURITY BY ITS ACCEPTANCE THEREOF, HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT IT MAY HAVE TO TRIAL BY
JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THE INDENTURE, THE NOTES OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY. 

All terms used in this Note which are defined in the Indenture and not otherwise defined herein shall have the meanings
assigned to them in the Indenture. 
 No recourse under or upon any obligation, covenant or agreement contained in the
Indenture, or this Note, or because of any indebtedness evidenced thereby, shall be had against any incorporator, as such or against any past, present or future stockholder, Officer, director or employee, as such, of the Company or of any successor,
either directly or through the Company or any successor, under any rule of law, statute or constitutional provision or by the enforcement of any assessment or by any legal or equitable proceeding or otherwise, all such liability being expressly
waived and released by the acceptance of this Note by the Holders hereof and as part of the consideration for the issue of this Note. 

The Company and each Holder agrees, and by acceptance of a beneficial ownership interest in the Notes, each beneficial owner
of a beneficial ownership interest in the Notes will be deemed to have agreed, for U.S. federal, state and local tax purposes, to treat the Notes as indebtedness. 

In the case of any conflict between this Note and the Indenture, the provisions of the Indenture shall control.
