 [REVERSE SIDE OF NOTE] 

HANCOCK HOLDING COMPANY 

5.95% Subordinated Note due 2045 
  

	1.	Principal and Interest. 

 The Company promises to pay the principal of this Note on
June 15, 2045. 
 The Company promises to pay interest on the principal amount of this Note on each Interest Payment Date, as set forth
on the face of this Note, at the rate of 5.95% per annum. 
 Interest will be payable quarterly on each Interest Payment Date,
commencing June 15, 2015, to the Holders of record of the Notes at the close of business on the Regular Record Date (whether or not a Business Day), as set forth on the face of this Note, immediately preceding each Interest Payment Date. 

Interest on this Note will accrue from the most recent date to which interest has been paid or duly provided for on this Note (or, if there is
no existing default in the payment of interest and if this Note is authenticated between a Regular Record Date and the next Interest Payment Date, from such Interest Payment Date) or, if no interest has been paid or duly provided for, from
March 9, 2015. Interest will be computed on the basis of a 360-day year of twelve 30-day months. 
  

	2.	Indenture and Subordination. 

 This Global Security is one of a duly authorized issue of
securities of the Company (herein called the “Notes”) issued under the Indenture, dated as of March 9, 2015 (the “Indenture”), between the Company and The Bank of New York Mellon Trust Company, N.A., as Trustee. Capitalized
terms used herein are used as defined in the Indenture unless otherwise indicated. The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act. The Notes are subject to
all such terms, and Holders are referred to the Indenture and the Trust Indenture Act for a statement of all such terms. To the extent permitted by applicable law, in the event of any inconsistency between the terms of this Note and the terms of the
Indenture, the terms of the Indenture will control. 
 The Indebtedness evidenced by the Notes is, to the extent and in the manner set forth
in the Indenture subordinate and subject in right of payment to the prior payment in full of the principal of and premium, if any, and interest on all Senior Indebtedness of the Company and each Holder of a Note, by accepting the same, agrees to and
shall be bound by the provisions of the Indenture with respect thereto. 
 The Notes are general unsecured obligations of the Company. The
Notes will initially be limited to an original aggregate principal amount of $150,000,000, but additional Notes may be issued pursuant to the Indenture, and the originally issued Notes and any such additional Notes shall constitute a single series
of Securities under the Indenture and the originally issued Notes and any such additional Notes shall vote together for all purposes as a single class. 







	3.	Redemption; Discharge Prior to Redemption or Maturity. 

 This Note is subject to
redemption by the Company in whole or in part from time to time on June 15, 2020, or on any Interest Payment Date thereafter, at a Redemption Price equal to 100% of the principal amount of the Notes being redeemed plus accrued and unpaid
interest to, but not including, the date of the redemption, subject to the approval of the Federal Reserve, if then required. If the Company redeems only a portion of the Notes on any date of redemption, it may subsequently redeem additional Notes.

 Notice of any redemption will be mailed or transmitted at least 30 days but not more than 60 days before the redemption date to each
Holder of the Notes to be redeemed at its registered address. Unless the Company defaults in payment of the Redemption Price on the Notes, on and after the Redemption Date, interest will cease to accrue on the Notes or portions called for
redemption. 
 There is no sinking fund or mandatory redemption applicable to this Note. 

The Notes may be defeased by the Company, pursuant to Section 13.02 of the Indenture, provided the Company irrevocably deposits with the
Trustee money or U.S. Government Securities sufficient to pay the then Outstanding principal of and accrued interest on the Notes to redemption or maturity and the Company may in certain circumstances be discharged from the Indenture and the Notes.

  

	4.	Registered Form; Denominations; Transfer; Exchange. 

 The Notes are in registered form
without coupons in denominations of $25 principal amount and any multiple of $25 in excess thereof. A Holder may register the transfer or exchange of Notes in accordance with the Indenture. The Company or Security Registrar may require a Holder to
furnish appropriate endorsements and transfer documents and to pay any taxes and fees required by law or permitted by the Indenture. Pursuant to the Indenture, there are certain periods during which the Company will not be required to issue,
register the transfer of or exchange any Note or certain portions of a Note. 
  

	5.	Defaults and Remedies. 

 In case an Event of Default with respect to the Notes shall have
occurred and be continuing, the principal hereof may be declared, and upon such declaration shall become, due and payable immediately, in the manner, with the effect and subject to the conditions provided in the Indenture. 

The Indenture provides that in the event of a Default in the payment of interest or principal or the performance of any covenant or agreement
in the Notes or the Indenture (each of which is defined in the Indenture to be a “Default”), the Trustee may, subject to certain limitations and conditions, seek to enforce payment of such interest or principal or the performance of such
covenant agreement. There will be no right of acceleration in the case of a Default.

	6.	Amendment and Waiver. 

 Subject to certain exceptions, the Indenture and the Notes may be
amended, or default may be waived, with the consent of the Holders of a majority in principal amount of the Outstanding Notes. Without notice to or the consent of any Holder, the Company and the Trustee may amend or supplement the Indenture or the
Notes to, among other things, cure any ambiguity, or to correct or supplement any provision therein which may be defective or inconsistent with any other provision therein. 
  

	7.	Authentication. 

 This Note is not valid until the Trustee signs the certificate of
authentication on the other side of this Note. 
  

	8.	Abbreviations. 

 Customary abbreviations may be used in the name of a Holder or an
assignee, such as: TEN COM (= tenants in common), TEN ENT (= tenants by the entireties), JT TEN (= joint tenants with right of survivorship and not as tenants in common), CUST (= Custodian) and U/G/M/A/ (= Uniform Gifts to Minors Act).
