 REVERSE OF COMMON SECURITY 
  
 Distributions payable on each Common Security will be payable at an annual rate equal to 4.1075% beginning on (and
including) the date of original issuance and ending on (but excluding) the Distribution Payment Date in September 2004 and at an annual rate for each successive period beginning on (and including) the Distribution Payment Date in September 2004, and
each succeeding Distribution Payment Date, and ending on (but excluding) the next succeeding Distribution Payment Date (each a “Distribution Period”), equal to 3-Month LIBOR, determined as described below, plus 2.68% (the “Coupon
Rate”), applied to the stated liquidation amount of $1,000.00 per Common Security, such rate being the rate of interest payable on the Debentures to be held by the Institutional Trustee. The term “Distributions” as used herein
includes cash distributions and any such compounded distributions unless otherwise noted. A Distribution is payable only to the extent that payments are made in respect of the Debentures held by the Institutional Trustee and to the extent the
Institutional Trustee has funds available therefor. As used herein, “Determination Date” means the date that is two London Banking Days (i.e., a business day in which dealings in deposits in U.S. dollars are transacted in the London
interbank market) preceding the commencement of the relevant Distribution Period. The amount of the Distribution payable for any Distribution Period will be calculated by applying the Distribution Rate to the stated liquidation amount outstanding at
the commencement of the Distribution Period on the basis of the actual number of days in the Distribution Period concerned divided by 360. 
  
 “3-Month LIBOR” as used herein, means the London interbank offered interest rate for three-month U.S. dollar deposits determined by the
Debenture Trustee in the following order of priority: (i) the rate (expressed as a percentage per annum) for U.S. dollar deposits having a three-month maturity that appears on Telerate Page 3750 as of 11:00 a.m. (London time) on the related
Determination Date (“Telerate Page 3750” means the display designated as “Page 3750” on the Dow Jones Telerate Service or such other page as may replace Page 3750 on that service or such other service or services as may be
nominated by the British Bankers’ Association as the information vendor for the purpose of displaying London interbank offered rates for U.S. dollar deposits); (ii) if such rate cannot be identified on the related Determination Date, the
Debenture Trustee will request the principal London offices of four leading banks in the London interbank market to provide such banks’ offered quotations (expressed as percentages per annum) to prime banks in the London interbank market for
U.S. dollar deposits having a three-month maturity as of 11:00 a.m. (London time) on such Determination Date. If at least two quotations are provided, 3-Month LIBOR will be the arithmetic mean of such quotations; (iii) if fewer than two such
quotations are provided as requested in clause (ii) above, the Debenture Trustee will request four major New York City banks to provide such banks’ offered quotations (expressed as percentages per annum) to leading European banks for loans in
U.S. dollars as of 11:00 a.m. (London time) on such Determination Date. If at least two such quotations are provided, 3-Month LIBOR will be the arithmetic mean of such quotations; and (iv) if fewer than two such quotations are provided as requested
in clause (iii) above, 3-Month LIBOR will be a 3-Month LIBOR determined with respect to the Distribution Period immediately preceding such current Distribution Period. If the rate for U.S. dollar deposits having a three-month maturity that initially
appears on Telerate Page 3750 as of 11:00 a.m. (London time) on the related Determination Date is superseded on the Telerate Page 3750 by a corrected rate by 12:00 noon (London time) on such Determination Date, then the corrected rate as so
substituted on the applicable page will be the applicable 3-Month LIBOR for such Determination Date. 
  
 The Distribution Rate for any Distribution Period will at no time be higher than the maximum rate then permitted by New York law as the same may be
modified by United States law. 
  
 All percentages resulting from
any calculations on the Common Securities will be rounded, if necessary, to the nearest one hundred-thousandth of a percentage point, with five one-millionths of a percentage point rounded upward (e.g., 9.876545% (or .09876545) being rounded to
9.87655% (or .0987655), and all dollar amounts used in or resulting from such calculation will be rounded to the nearest cent (with one-half cent being rounded upward)). 
  
 Except as otherwise described below, Distributions on the Common Securities will be cumulative, will accrue from the date of
original issuance and will be payable quarterly in arrears on March 17, June 17, September 17 and December 17 of each year or if any such day is not a Business Day, then the next succeeding Business Day (each such day, a “Distribution Payment
Date”), commencing on the Distribution Payment Date in September 2004. The Debenture Issuer has the right under the Indenture to defer payments of interest on the Debentures, so long as no Extension Event of Default has occurred and is
continuing, by extending the interest payment period for up to 20 consecutive quarterly periods (each an “Extension Period”) at any time and from time to time on the Debentures, subject to the conditions described below, during which
Extension Period no interest shall be due and payable. During any Extension Period, interest will continue to accrue on the Debentures, and interest on such accrued interest will accrue at an annual rate equal to the Distribution Rate in effect for
each such Extension Period, compounded quarterly from the date such interest would have been payable were it not for the Extension Period, to the extent permitted by law (such interest referred to herein as “Additional Interest”). No
Extension Period may end on a date other than a Distribution Payment Date. At the end of any such Extension Period, the Debenture Issuer shall pay all interest then accrued and unpaid on the Debentures (together with Additional Interest thereon);
provided, however, that no Extension Period may extend beyond the Maturity Date. Prior to the termination of any Extension Period, the Debenture Issuer may further extend such period, provided that such period together with all such
previous and further consecutive extensions thereof shall not exceed 20 consecutive quarterly periods, or extend beyond the Maturity Date. Upon the termination of any Extension Period and upon the payment of all accrued and unpaid interest and
Additional Interest, the Debenture Issuer may commence a new Extension Period, subject to the foregoing requirements. No interest or Additional Interest shall be due and payable during an Extension Period, except at the end thereof, but each
installment of interest that would otherwise have been due and payable during such Extension Period shall bear Additional Interest. During any Extension Period, Distributions on the Common Securities shall be deferred for a period equal to the
Extension Period. If Distributions are deferred, the Distributions due shall be paid on the date that the related Extension Period terminates, to Holders of the Securities as they appear on the books and records of the Trust on the record date
immediately preceding such date. Distributions on the Securities must be paid on the dates payable (after giving effect to any Extension Period) to the extent that the Trust has funds available for the payment of such distributions in the Property
Account of the Trust. The Trust’s funds available for Distribution to the Holders of the Securities will be limited to payments received from the Debenture Issuer. 
  
 The Common Securities shall be redeemable as provided in the Declaration.

Deferrable Interest Debenture 
  
 of 
  
 Taylor Capital Group, Inc. 
  
 June 17, 2004 
  
 Taylor Capital Group, Inc., a Delaware corporation (the “Company” which term includes any successor Person under
the Indenture hereinafter referred to), for value received promises to pay to Wilmington Trust Company, not in its individual capacity but solely as Institutional Trustee for TAYC Capital Trust II (the “Holder”) or registered assigns, the
principal sum of forty-one million two hundred thirty-eight thousand dollars ($41,238,000.00) on June 17, 2034, and to pay interest on said principal sum from June 17, 2004, or from the most recent Interest Payment Date (as defined below) to which
interest has been paid or duly provided for, quarterly (subject to deferral as set forth herein) in arrears on March 17, June 17, September 17 and December 17 of each year or if such day is not a Business Day, then the next succeeding Business Day
(each such date, an “Interest Payment Date”) (it being understood that interest accrues for any such non-Business Day), commencing on the Interest Payment Date in September 2004, at an annual rate equal to 4.1075% beginning on (and
including) the date of original issuance and ending on (but excluding) the Interest Payment Date in September 2004 and at an annual rate for each successive period beginning on (and including) the Interest Payment Date in September 2004, and each
succeeding Interest Payment Date, and ending on (but excluding) the next succeeding Interest Payment Date (each a “Distribution Period”), equal to 3-Month LIBOR, determined as described below, plus 2.68% (the “Coupon Rate”),
applied to the principal amount hereof, 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 (including Additional Interest) at the Interest Rate in effect for each applicable period, compounded quarterly, from the dates such amounts are due until they are paid or made available for
payment. The amount of interest payable for any period will be computed on the basis of the actual number of days in the Distribution Period concerned divided by 360. 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 Debenture (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 five days prior to the day on which the relevant
Interest Payment Date occurs. 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 be paid to the Person in whose name this Debenture (or one
or more Predecessor Securities) is registered at the close of business on a special record date. 
  
 “3-Month LIBOR” as used herein, means the London interbank offered interest rate for three-month U.S. dollar deposits determined by the Trustee
in the following order of priority: (i) the rate (expressed as a percentage per annum) for U.S. dollar deposits having a three-month maturity that appears on Telerate Page 3750 as of 11:00 a.m. (London time) on the related Determination Date
(“Telerate Page 3750” means the display designated as “Page 3750” on the Dow Jones Telerate Service or such other page as may replace Page 3750 on that service or such other service or services as may be nominated by the British
Bankers’ Association as the information vendor for the purpose of displaying London interbank offered rates for U.S. dollar deposits); (ii) if such rate cannot be identified on the related Determination Date, the Trustee will request the
principal London offices of four leading banks in the London interbank market to provide such banks’ offered quotations (expressed as percentages per annum) to prime banks in the London interbank market for U.S. dollar deposits having a
three-month maturity as of 11:00 a.m. (London time) on such Determination Date. If at least two quotations are provided, 3-Month LIBOR will be the arithmetic mean of such quotations; (iii) if fewer than two such quotations are provided as requested
in clause (ii) above, the Trustee will request four major New York City banks to provide such banks’ offered quotations (expressed as percentages per annum) to leading European banks for loans in U.S. dollars as of 11:00 a.m. (London time) on
such Determination Date. If at least two such quotations are provided, 3-Month LIBOR will be the arithmetic mean of such quotations; and (iv) if fewer than two such quotations are provided as requested in clause (iii) above, 3-Month LIBOR will be a
3-Month LIBOR determined with respect to the Distribution Period immediately preceding such current Distribution Period. If the rate for U.S. dollar deposits having a three-month maturity that initially appears on Telerate Page 3750 as of 11:00 a.m.
(London time) on the related Determination Date is superseded on the Telerate Page 3750 by a corrected rate by 12:00 noon (London time) on such Determination Date, then the corrected rate as so substituted on the applicable page will be the
applicable 3-Month LIBOR for such Determination Date. As used herein, “Determination Date” means the date that is two London Banking Days (i.e., a business day in which dealings in deposits in U.S. dollars are transacted in the London
interbank market) preceding the commencement of the relevant Distribution Period. 
  
 The Interest Rate for any Distribution Period will at no time be higher than the maximum rate then permitted by New York law as the same may be modified by United States law. 
  
 All percentages resulting from any calculations on the Debentures will be
rounded, if necessary, to the nearest one hundred-thousandth of a percentage point, with five one-millionths of a percentage point rounded upward (e.g., 9.876545% (or .09876545) being rounded to 9.87655% (or .0987655), and all dollar amounts used in
or resulting from such calculation will be rounded to the nearest cent (with one-half cent being rounded upward)). 
  
 The principal of and interest on this Debenture shall be payable at the office or agency of the Trustee (or other paying agent appointed by the Company)
maintained for that purpose in any coin or currency of the United States of America that at the time of payment is legal tender for payment of public and private debts; provided, however, that payment of interest may be made by check
mailed to the registered holder at such address as shall appear in the Debenture Register if a request for a wire transfer by such holder has not been received by the Company or by wire transfer to an account appropriately designated by the holder
hereof. Notwithstanding the foregoing, so long as the holder of this Debenture is the Institutional Trustee, the payment of the principal of and interest on this Debenture will be made in immediately available funds at such place and to such account
as may be designated by the Trustee. 
  

 So long as no Extension Event of Default has occurred and is continuing, the Company shall have the
right, from time to time, and without causing an Event of Default, to defer payments of interest on the Debentures by extending the interest payment period on the Debentures at any time and from time to time during the term of the Debentures, for up
to 20 consecutive quarterly periods (each such extended interest payment period, an “Extension Period”), during which Extension Period no interest (including Additional Interest) shall be due and payable (except any Additional Sums that
may be due and payable). No Extension Period may end on a date other than an Interest Payment Date. During an Extension Period, interest will continue to accrue on the Debentures, and interest on such accrued interest will accrue at an annual rate
equal to the Interest Rate in effect for such Extension Period, compounded quarterly from the date such interest would have been payable were it not for the Extension Period, to the extent permitted by law (such interest referred to herein as
“Additional Interest”). At the end of any such Extension Period the Company shall pay all interest then accrued and unpaid on the Debentures (together with Additional Interest thereon); provided, however, that no Extension
Period may extend beyond the Maturity Date; provided further, however, that during any such Extension Period, the Company shall not and shall not permit any Affiliate to engage in any of the activities or transactions described on the
reverse side hereof and in the Indenture. Prior to the termination of any Extension Period, the Company may further extend such period, provided that such period together with all such previous and further consecutive extensions thereof shall not
exceed 20 consecutive quarterly periods, or extend beyond the Maturity Date. Upon the termination of any Extension Period and upon the payment of all accrued and unpaid interest and Additional Interest, the Company may commence a new Extension
Period, subject to the foregoing requirements. No interest or Additional Interest shall be due and payable during an Extension Period, except at the end thereof, but each installment of interest that would otherwise have been due and payable during
such Extension Period shall bear Additional Interest. The Company must give the Trustee notice of its election to begin or extend an Extension Period by the close of business at least 5 Business Days prior to the Interest Payment Date with respect
to which interest on the Debentures would have been payable except for the election to begin or extend such Extension Period. Notwithstanding the foregoing sentence, a notice of election to commence a new Extension Period delivered to the Trustee
after an Interest Payment Date on which the Company defaulted in the payment of interest but before the next succeeding Interest Payment Date occurs shall be deemed to be valid notice with the same effect as if it were delivered in accordance with
the preceding sentence. 
  
 The indebtedness evidenced by this
Debenture is, to the extent provided in the Indenture, subordinate and junior in right of payment to the prior payment in full of all Senior Indebtedness, and this Debenture is issued subject to the provisions of the Indenture with respect thereto.
Each holder of this Debenture, by accepting the same, (a) agrees to and shall be bound by such provisions, (b) 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 so provided and (c) appoints the Trustee his or her attorney-in-fact for any and all such purposes. Each holder hereof, by his or her acceptance hereof, hereby waives all notice of the acceptance of the subordination
provisions contained herein and in the Indenture by each holder of Senior Indebtedness, whether now outstanding or hereafter incurred, and waives reliance by each such holder upon said provisions. 
  
 This Debenture shall not be entitled to any benefit under the Indenture
hereinafter referred to, be valid or become obligatory for any purpose until the certificate of authentication hereon shall have been signed by or on behalf of the Trustee. 
  
 The provisions of this Debenture are continued on the reverse side hereof and such provisions shall for all purposes have
the same effect as though fully set forth at this place.

 REVERSE OF DEBENTURE 
  
 This Debenture is one of the floating rate junior subordinated deferrable interest debentures of the Company, all issued or
to be issued under and pursuant to the Indenture dated as of June 17, 2004 (the “Indenture”), duly executed and delivered between the Company and the Trustee, 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 of the Debentures. The Debentures are limited in aggregate principal amount as specified in the Indenture. 
  
 Upon the occurrence and continuation of a Special Event prior to the Interest
Payment Date in June 2009, the Company shall have the right to redeem the Debentures in whole, but not in part, at any Interest Payment Date, within 120 days following the occurrence of such Special Event, at the Special Redemption Price.

  
 In addition, the Company shall have the right to redeem the
Debentures, in whole or in part, but in all cases in a principal amount with integral multiples of $1,000.00, on any Interest Payment Date on or after the Interest Payment Date in June 2009, at the Redemption Price. 
  
 Prior to 10:00 a.m. New York City time on the Redemption Date or Special
Redemption Date, as applicable, the Company will deposit with the Trustee or with one or more paying agents an amount of money sufficient to redeem on the Redemption Date or the Special Redemption Date, as applicable, all the Debentures so called
for redemption at the appropriate Redemption Price or Special Redemption Price. 
  
 If all, or less than all, the Debentures are to be redeemed, the Company will give the Trustee notice not less than 30 nor more than 60 days, respectively, prior to the Redemption Date or Special Redemption Date, as
applicable, as to the aggregate principal amount of Debentures to be redeemed and the Trustee shall select, in such manner as in its sole discretion it shall deem appropriate and fair, the Debentures or portions thereof (in integral multiples of
$1,000.00) to be redeemed. 
  
 Notwithstanding the foregoing, any
redemption of Debentures by the Company shall be subject to the receipt of any and all required regulatory approvals. 
  
 In case an Event of Default shall have occurred and be continuing, upon demand of the Trustee, the principal of all of the Debentures shall become due and
payable in the manner, with the effect and subject to the conditions provided in the Indenture. 
  
 The Indenture contains provisions permitting the Company and the Trustee, with the consent of the holders of not less than a majority in aggregate
principal amount of the Debentures at the time outstanding, to execute supplemental indentures for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of this Indenture or of any supplemental
indenture or of modifying in any manner the rights of the holders of the Debentures; provided, however, that no such supplemental indenture shall without the consent of the holders of each Debenture then outstanding and affected
thereby (i) change the fixed maturity of any Debenture, or reduce the principal amount thereof or any premium thereon, or reduce the rate or extend the time of payment of interest thereon, or reduce any amount payable on redemption thereof or make
the principal thereof or any interest or premium thereon payable in any coin or currency other than that provided in the Debentures, or impair or affect the right of any Securityholder to institute suit for payment thereof or impair the right of
repayment, if any, at the option of the holder, or (ii) reduce the aforesaid percentage of Debentures the holders of which are required to consent to any such supplemental indenture. 
  
 The Indenture also contains provisions permitting the holders of a majority in aggregate principal amount of the Debentures
at the time outstanding on behalf of the holders of all of the Debentures to waive (or modify any previously granted waiver of) any past default or Event of Default, and its consequences, except a default (a) in the payment of principal of, premium,
if any, or interest on any of the Debentures, (b) in respect of covenants or provisions hereof or of the Indenture which cannot be modified or amended without the consent of the holder of each Debenture affected, or (c) in respect of the covenants
contained in Section 3.9 of the Indenture; provided, however, that if the Debentures are held by the Trust or a trustee of such trust, such waiver or modification to such waiver shall not be effective until the holders of a majority in
Liquidation Amount of Trust Securities of the Trust shall have consented to such waiver or modification to such waiver, provided, further, that if the consent of the holder of each outstanding Debenture is required, such waiver shall
not be effective until each holder of the Trust Securities of the Trust shall have consented to such waiver. Upon any such waiver, the default covered thereby shall be deemed to be cured for all purposes of the Indenture and the Company, the Trustee
and the holders of the Debentures shall be restored to their former positions and rights hereunder, respectively; but no such waiver shall extend to any subsequent or other default or Event of Default or impair any right consequent thereon. Whenever
any default or Event of Default hereunder shall have been waived as permitted by the Indenture, said default or Event of Default shall for all purposes of the Debentures and the Indenture be deemed to have been cured and to be not continuing.

  
 No reference herein to the Indenture and no provision of this
Debenture or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and premium, if any, and interest, including Additional Interest, on this Debenture at the time and place
and at the rate and in the money herein prescribed. 
  
 The
Company has agreed that if Debentures are initially issued to the Trust or a trustee of such Trust in connection with the issuance of Trust Securities by the Trust (regardless of whether Debentures continue to be held by such Trust) and (i) there
shall have occurred and be continuing an Event of Default, (ii) the Company shall be in default with respect to its payment of any obligations under the Capital Securities Guarantee, or (iii) the Company shall have given notice of its election to
defer payments of interest on the Debentures by extending the interest payment period as provided herein and such Extension Period, or any extension thereof, shall be continuing, then the Company shall not, and shall not allow any Affiliate of the
Company to, (x) 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 or its Affiliates’ capital stock (other than payments of
dividends or distributions to the Company) or make any guarantee payments with respect to the foregoing or (y) make any payment of principal of or interest or premium, if any, on or repay, repurchase or redeem any debt securities of the Company or
any Affiliate that rank pari passu in all respects with or junior in interest to the Debentures (other than, with respect to clauses (x) and (y) above, (1) repurchases, 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 one or more employees, officers, directors or consultants, in connection with a dividend reinvestment or stockholder stock
purchase 

  

 
plan or in connection with the issuance of capital stock of the Company (or securities convertible into or exercisable for such capital stock) as
consideration in an acquisition transaction entered into prior to the applicable Extension Period, if any, (2) as a result of any exchange or conversion of any class or series of the Company’s capital stock (or any capital stock of a subsidiary
of the Company) for any class or series of the Company’s capital stock or of any class or series of the Company’s indebtedness for any class or series of the Company’s capital stock, (3) 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, (4) any declaration of a dividend in connection with any stockholders’ rights plan, or the
issuance of rights, stock or other property under any stockholders’ rights plan, or the redemption or repurchase of rights pursuant thereto, (5) any dividend in the form of stock, warrants, options or other rights where the dividend stock or
the stock issuable upon exercise of such warrants, options or other rights is the same stock as that on which the dividend is being paid or ranks pari passu with or junior to such stock and any cash payments in lieu of fractional shares
issued in connection therewith, or (6) payments under the Capital Securities Guarantee). 
  
 The Debentures are issuable only in registered, certificated form without coupons and in minimum denominations of $100,000.00 and any multiple of $1,000.00 in excess thereof. As provided in the Indenture and subject
to the transfer restrictions and limitations as may be contained herein and therein from time to time, this Debenture is transferable by the holder hereof on the Debenture Register of the Company. Upon due presentment for registration of transfer of
any Debenture at the Principal Office of the Trustee or at any office or agency of the Company maintained for such purpose as provided in Section 3.2 of the Indenture, the Company shall execute, the Company or the Trustee shall register and the
Trustee or the Authenticating Agent shall authenticate and make available for delivery in the name of the transferee or transferees a new Debenture for a like aggregate principal amount. All Debentures presented for registration of transfer or for
exchange or payment shall (if so required by the Company or the Trustee or the Authenticating Agent) be duly endorsed by, or be accompanied by a written instrument or instruments of transfer in form satisfactory to, the Company and the Trustee or
the Authenticating Agent duly executed by the holder or his attorney duly authorized in writing. No service charge shall be made for any exchange or registration of transfer of Debentures, but the Company or the Trustee may require payment of a sum
sufficient to cover any tax, fee or other governmental charge that may be imposed in connection therewith. 
  
 Prior to due presentment for registration of transfer of any Debenture, the Company, the Trustee, any Authenticating Agent, any paying agent, any transfer
agent and any Debenture registrar may deem the Person in whose name such Debenture shall be registered upon the Debenture Register to be, and may treat him as, the absolute owner of such Debenture (whether or not such Debenture shall be overdue) for
the purpose of receiving payment of or on account of the principal of, premium, if any, and interest on such Debenture and for all other purposes; and neither the Company nor the Trustee nor any Authenticating Agent nor any paying agent nor any
transfer agent nor any Debenture registrar shall be affected by any notice to the contrary. All such payments so made to any holder for the time being or upon his order shall be valid, and, to the extent of the sum or sums so paid, effectual to
satisfy and discharge the liability for moneys payable upon any such Debenture. 
  
 No recourse for the payment of the principal of or premium, if any, or interest on any Debenture, or for any claim based thereon or otherwise in respect thereof, and no recourse under or upon any obligation, covenant
or agreement of the Company in the Indenture or in any supplemental indenture, or in any such Debenture, or because of the creation of any indebtedness represented thereby, shall be had against any incorporator, stockholder, employee, officer or
director, as such, past, present or future, of the Company or of any successor Person of the Company, either directly or through the Company or any successor Person of the Company, whether by virtue of any constitution, statute or rule of law, or by
the enforcement of any assessment or penalty or otherwise, it being expressly understood that all such liability is hereby expressly waived and released as a condition of, and as a consideration for, the execution of the Indenture and the issue of
the Debentures. 
  
 Capitalized terms used and not defined in this
Debenture shall have the meanings assigned in the Indenture dated as of the date of original issuance of this Debenture between the Trustee and the Company. 
  
 THE INDENTURE AND THE DEBENTURES SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD TO CONFLICT OF LAW
PRINCIPLES THEREOF.
