 OTHER TERMS: 

All terms used in this Security that are not defined in this Security but are defined in the Indenture referred to on the reverse of this
Security shall have the meanings assigned to them in the Indenture. Section headings on the face of this Security are for convenience only and shall not affect the construction of this Security. 

“3-Month LIBOR” means, for any Interest Reset Date, the rate for deposits in U.S. Dollars for a period of 3 months which
appears on Reuters Page LIBOR01 as of 11:00 a.m. London time on the related Interest Determination Date. If no Rate appears on Reuters Page LIBOR01 (or any successor thereto), the Calculation Agent shall determine 3-Month LIBOR in accordance with
the procedures set forth under “3-Month LIBOR Fallbacks” below. 
 “Beneficial Owners” shall mean (a) with
respect to Global Securities, the beneficial owners of the Securities (b) with respect to definitive Securities, the Holders in whose names the Securities are registered in the Senior Debt Security Register. 

“Business Day” means any day that is a Monday, Tuesday, Wednesday, Thursday or Friday that is not a day on which banking
institutions in New York City or London, generally, are authorized or obligated by law, regulation or executive order to close. 

“Calculation Agent” means the Company, or any successor thereto appointed by the Company. 

“Day Count Fraction” means the day count fraction calculated by dividing the actual number of days in each Interest Period by
360. 
 “Default Amount” means, on any day, an amount in U.S. dollars, as determined by the Calculation Agent, equal to the
cost of having a Qualified Financial Institution (selected as provided below) expressly assume the due and punctual payment of the principal of this Security, and the performance or observance of every covenant hereof and of the Indenture on the
part of the Company to be performed or observed with respect to this Security (or to undertake other obligations providing substantially equivalent economic value to the Holder of this Security as the Company’s obligations hereunder). Such cost
will equal (i) the lowest amount that a Qualified Financial Institution would charge to effect such assumption (or undertaking) plus (ii) the reasonable expenses (including reasonable attorneys’ fees) incurred by the Holder of this
Security in preparing any documentation necessary for such assumption (or undertaking). During the Default Quotation Period, each Holder of this Security and the Company may request a Qualified Financial Institution to provide a quotation of the
amount it would charge to effect such assumption (or undertaking) and notify the other in writing of such quotation. The amount referred to in clause (i) of this paragraph will equal the lowest (or, if

 
there is only one, the only) quotation so obtained, and as to which notice is so given, during the Default Quotation Period; provided that, with respect to any quotation, the party not
obtaining such quotation may object, on reasonable and significant grounds, to the effectuation of such assumption (or undertaking) by the Qualified Financial Institution providing such quotation and notify the other party in writing of such grounds
within two Business Days after the last day of the Default Quotation Period, in which case such quotation will be disregarded in determining the Default Amount. The “Default Quotation Period” will be the period beginning on the day
the Default Amount first becomes due and ending on the third Business Day after such due date, unless no such quotation is so obtained, or unless every such quotation so obtained is objected to within five Business Days after such due date as
provided above, in which case the Default Quotation Period will continue until the third Business Day after the first Business Day on which prompt notice is given of such quotation as provided above, unless such quotation is objected to as provided
above within five Business Days after such first Business Day, in which case the Default Quotation Period will continue as provided in this sentence. Notwithstanding the foregoing, if the Default Quotation Period (and the subsequent two Business Day
objection period) has not ended prior to the Stated Maturity Date, then the Default Amount will equal the Principal Amount. 

“DTC” means The Depository Trust Company, or any successor clearing system. 

“Qualified Financial Institution” means, at any time, a financial institution organized under the laws of any jurisdiction in
the United States or Europe that at such time has outstanding debt obligations with a stated maturity of one year or less from the date of issue and rated A-1 or higher by Standard & Poor’s, a
division of The McGraw-Hill Companies, Inc., (or any successor) or P-1 or higher by Moody’s Investors Service, Inc. (or any successor) or, in either case, such other comparable rating, if any, then used
by such rating agency. 
 “Stated Maturity Date” means December 9, 2016. 

“U.K. Bail-In Power” means any statutory write-down and/or conversion power existing from time to time under any laws,
regulations, rules or requirements relating to the resolution of banks, banking group companies, credit institutions and/or investment firms incorporated in the United Kingdom in effect and applicable in the United Kingdom to the Company or other
members of the Group, including but not limited to any such laws, regulations, rules or requirements that are implemented, adopted or enacted within the context of a European Union directive or regulation of the European Parliament and of the
Council establishing a framework for the recovery and resolution of credit institutions and investment firms, and/or within the context of a U.K. resolution regime by way of amendment to the U.K. Banking Act 2009, as amended, or otherwise, pursuant
to which obligations of a bank, banking group company, credit institution or investment firm or any of its affiliates can be reduced, cancelled and/or converted into shares or other securities or obligations of the Company or any other person (and a
reference to the “Relevant U.K. Resolution Authority” is to any authority with the ability to exercise a U.K. Bail-In Power). 

1. Promise to Pay Principal and Interest. Barclays Bank PLC, a public limited company duly organized and existing under the laws of
England and Wales (herein called the “Company,” which term includes any successor Person under the Indenture hereinafter 

 
referred to), for value received, hereby promises to pay (or cause to be paid) to Cede & Co., as nominee for The Depository Trust Company, or registered assigns, the principal sum,
calculated as provided under “Principal Amount” and elsewhere on the face of this Security, on the Stated Maturity Date, and to pay interest on the outstanding Principal Amount quarterly, from the Original Issue Date, or from the most
recent date to which interest has been paid or duly provided for, on the 9th day of each March, June, September and December in each year, commencing on (and including) March 9, 2014 (each an
“Interest Payment Date”), subject to the Business Day Convention, at the rate calculated as provided under “Interest Rate” and elsewhere on the face of this Security, until the principal of this Security is paid or made
available for payment. Any interest amounts that are overdue at any time shall also bear interest, at the then prevailing 3-Month LIBOR rate (to the extent that payment of such interest shall be legally enforceable), from the dates such amounts are
due until they are paid or made available for payment. Notwithstanding the foregoing, (i) if the Stated Maturity Date does not occur on December 9, 2016 then the Interest Payment Date that would otherwise occur on December 9, 2016
shall instead occur on the Stated Maturity Date and (ii) interest on any overdue amount shall be payable on demand. 
 2. Payment of
Interest. The interest so payable, and punctually paid or made available for payment, 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 Payment Date, which shall be the first Business Day next preceding such Interest Payment Date, provided that for an Interest Payment Date that is also the Maturity
Date, the interest payable on that Interest Payment Date will be payable to the Person to whom the principal is payable. The “close of business” for making such determination shall mean 5:00 p.m., New York City time on such date. Any
interest so payable, but not punctually paid or made available for payment, on any Interest Payment Date will forthwith cease to be payable to the Holder on such Regular Record Date and such Defaulted Interest 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 the Holder of
this Security not less than ten days prior to such Special Record Date, or be paid in any other lawful manner not inconsistent with the requirements of any securities exchange on which this Security may be listed, and upon such notice as may be
required by such exchange, all as more fully provided in the Indenture. 
 For any Interest Payment Date, the Calculation Agent shall
calculate the interest payable by multiplying the relevant principal amount by the Interest Rate specified herein and the applicable Day Count Fraction. Any return on this Security that may be deemed to be interest will in no event be higher than
the maximum rate permitted by New York law, as it may be modified by U.S. law of general application. 
 3. Principal Amount. The
principal of this Security that becomes due and payable on the Stated Maturity Date shall be equal to the Principal Amount hereof. This Security shall cease to be Outstanding as provided in the definition of such term in the Indenture or when the
principal of this Security shall be deemed to have been paid in full as provided above and all interest payable on this Security has been paid (or such payment of interest has been made available). 

 4. Role of Calculation Agent. The Calculation Agent will be solely responsible for making
all determinations and calculations regarding the Default Amount; Business Days; the Principal Amount; the Interest Rate; and all such other matters as may be specified elsewhere herein as matters to be determined by the Calculation Agent. The
Calculation Agent shall make all such determinations and calculations in its sole discretion and, absent manifest error, all determinations of the Calculation Agent shall be final and binding on the Company, the Trustee, the Holder and all other
Persons having an interest in this Security, without any liability on the part of the Calculation Agent. 
 The Company shall take such
action as shall be necessary to ensure that there is, at all relevant times, a financial institution serving as the Calculation Agent hereunder. The Company may, in its sole discretion at any time and from time to time, upon written notice to the
Trustee, but without notice to the Holder of this Security, terminate the appointment of any Person serving as the Calculation Agent and appoint another Person (including the Company or any Affiliate of the Company) to serve as the Calculation
Agent. Insofar as this Security provides for the Calculation Agent to obtain information relating to the Reference Asset or other information from any institution or other source, the Calculation Agent may do so from any source or sources of the
kind contemplated or otherwise permitted hereby notwithstanding that any one or more of such sources are the Calculation Agent, Affiliates of the Calculation Agent or Affiliates of the Company. 

5. Payment. Payment of any amount payable on this Security in cash will be made 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. Payment of cash payable on this Security will be made to an account designated by the Holder (in writing to the Company and the Trustee) and approved by the
Company or, if no such account is designated and approved as aforesaid, at the office or agency of the Company maintained for that purpose in The City of New York (i.e., the office of the Trustee), provided, however, that, at
the option of the Company, payment of interest may be made by check mailed to the address of the Person entitled thereto as such address shall appear in the Senior Debt Security Register; and provided, further, that payment or delivery
at the Stated Maturity Date shall be made only upon surrender of this Security at such office or agency (unless the Company waives surrender). Notwithstanding the foregoing, if this Security is a Global Security, any payment may be made pursuant to
the Applicable Procedures of the Depositary as permitted in said Indenture. 
 6. 3-Month LIBOR Fallbacks. If no rate for 3-Month
LIBOR appears on Reuters Page LIBOR01 (or any successor thereto), then 3-Month LIBOR shall be determined as provided for under “Reference Assets—Floating Interest Rate—LIBOR” in the Prospectus Supplement. 

7. U.K. Bail-in Power Acknowledgment. No repayment of the Principal Amount of the Securities or payment of interest on the Securities
shall become due and payable after the exercise of any U.K. Bail-In Power by the Relevant U.K. Resolution Authority unless such repayment or payment would be permitted to be made by the Company under the laws and regulations of the
United Kingdom and the European Union applicable to the Company. 

 By its acquisition of the Securities, each Holder and Beneficial Owner of the Securities
acknowledges, agrees to be bound by and consents to the exercise of any U.K. Bail-In Power by the Relevant U.K. Resolution Authority that may result in the cancellation of all, or a portion, of the Principal Amount of, or interest on, the Securities
and/or the conversion of all, or a portion of, the Principal Amount of, or interest on, the Securities into shares or other securities or other obligations of the Company or another person, including by means of a variation to the terms of the
Securities to give effect to the exercise by the Relevant U.K. Resolution Authority of such U.K. Bail-In Power. Each Holder and Beneficial Owner further acknowledges and agrees that the rights of Holders and Beneficial Owners of the Securities are
subject to, and will be varied, if necessary, so as to give effect to, the exercise of any U.K. Bail-in Power by the Relevant U.K. Resolution Authority. 

By its acquisition of the Securities, each Holder and Beneficial Owner (i) acknowledges and agrees that no exercise of the U.K. Bail-In
Power by the Relevant U.K. Resolution Authority with respect to the Securities shall give rise to a default for purposes of Section 315(b) (Notice of Default) and Section 315(c) (Duties of the Trustee in Case of Default) of
the U.S. Trust Indenture Act of 1939, as amended, (ii) to the extent permitted by the Trust Indenture Act, waives any and all claims against the Trustee for, agrees not to initiate a suit against the Trustee in respect of, and agrees that the
Trustee shall not be liable for, any action that the Trustee takes, or abstains from taking, in either case in accordance with the exercise of the U.K. Bail-In Power by the Relevant U.K. Resolution Authority with respect to the Securities,
(iii) acknowledges and agrees that, upon the exercise of any U.K. Bail-In Power by the Relevant U.K. Resolution Authority, (a) the Trustee shall not be required to take any further directions from Holders or Beneficial Owners of the
Securities under Section 5.12 of the Indenture and (b) the Indenture shall impose no duties upon the Trustee whatsoever with respect to the exercise of any U.K. Bail-In Power by the Relevant U.K. Resolution Authority (notwithstanding the
foregoing in (iii), if, following the completion of the exercise of the U.K. Bail-In Power by the Relevant U.K. Resolution Authority, the Securities remain outstanding, then the Trustee’s duties under the Indenture shall remain applicable with
respect to the Securities following such completion to the extent that the Issuer and the Trustee shall agree pursuant to a supplemental indenture), and (iv) shall be deemed to have (a) consented to the exercise of any U.K. Bail-In Power
as it may be imposed without any prior notice by the Relevant U.K. Resolution Authority of its decision to exercise such power with respect to the Securities and (b) authorized, directed and requested DTC and any direct participant in DTC or
other intermediary through which it holds such Securities to take any and all necessary action, if required, to implement the exercise of any U.K. Bail-In Power with respect to the Securities as it may be imposed, without any further action or
direction on the part of such Holder and such Beneficial Owner. 
 Upon the exercise of the U.K. Bail-In Power by the Relevant U.K.
Resolution Authority with respect to the Securities, the Company shall provide a written notice to DTC as soon as practicable regarding such exercise of the U.K. Bail-In Power for purposes of notifying Holders and Beneficial Owners of such
occurrence. The Company shall also deliver a copy of such notice to the Trustee for information purposes. 
 The exercise of the U.K.
Bail-In Power by the Relevant U.K. Resolution Authority with respect to the Securities shall not constitute an Event of Default under the Indenture. 

 The Company’s obligations to indemnify the Trustee in accordance with Section 6.07 of
the Indenture shall survive any exercise of the U.K. Bail-In Power by the Relevant U.K. Resolution Authority with respect to the Securities. 

Each Holder and Beneficial Owner that acquires its Securities in the secondary market shall be deemed to acknowledge and agree to be bound by
and consent to the same provisions specified in this Security and the Indenture to the same extent as the Holders and Beneficial Owners of the Securities that acquire the Securities upon their initial issuance, including, without limitation, with
respect to the acknowledgement and agreement to be bound by and consent to the terms of the Securities, including in relation to the U.K. Bail-In Power. 

8. Default Amount. If an Event of Default occurs and the maturity of this Security is accelerated, the Default Amount will be payable
in respect of this Security at maturity. 
 9. Business Day Convention—Modified Following, Adjusted. Notwithstanding any
provision of this Security or of the Indenture, if any Interest Payment Date, other than the Maturity Date, would fall on a day (the “Specified Day”) that is not a Business Day, the Interest Payment Date will be postponed to the
next succeeding Business Day, except that if that Business Day falls in the next succeeding calendar month, the Interest Payment Date will be the immediately preceding Business Day, and such payment will be deemed made on that following or
succeeding Business Day (not on the Specified Day); accordingly, the amount of interest accrued and payable on that Interest Payment Date will be adjusted to reflect the longer or shorter interest period. If the Maturity Date would fall on a day
that is not a Business Day, the payment of interest and principal will be made on the next succeeding Business Day, but interest on that payment will not accrue during the period from and after such Maturity Date. The provisions of this Section
shall apply to this Security in lieu of the provisions of Section 1.13 of the Indenture. 
 10. Reverse of this Security.
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. 

11. Certificate of Authentication. 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. 

 12. Prospectus. Reference is made to the (i) the Prospectus related to the
Securities, dated July 19, 2013 (the “Base Prospectus”), (ii) the Prospectus Supplement, dated July 19, 2013 (the “Prospectus Supplement”) and (iii) the Pricing Supplement, dated December 2,
2013 (together with the Base Prospectus and the Prospectus Supplement, the “Prospectus”). The terms and conditions of this Security as fully set forth in the Prospectus are hereby incorporated by reference in their entirety into
this Security and binding upon the parties hereto. In the event of a conflict between the terms of the Prospectus and the terms of this Security (other than the terms specified under the captions “Interest Rate” in this Security), the
Prospectus will control and if the Prospectus provides for a specific United States tax characterization, by purchasing a Note, you agree (in the absence of a change in law, an administrative determination or a judicial ruling to the contrary) to be
bound for United States federal income tax purposes to such tax characterization. Copies of the Prospectus are available from the Company or any underwriter or any dealer participating in the offering by calling toll free, 1-888-227-2275 (extension
2-3430). The Trustee shall not be liable with respect to the adequacy of the disclosure in the Prospectus with respect to (i) the U.K. Bail-in Power or (ii) the other terms of the Note. 

 IN WITNESS WHEREOF, the Company has caused this instrument to be duly executed.

 (Reverse of Security) 

This Security is one of a duly authorized issue of securities of the Company (herein called the “Securities”) issued and to
be issued in one or more series under an Indenture, dated as of September 16, 2004 (herein called the “Indenture,” which term shall have the meaning assigned to it in such instrument), between the Company and The Bank of New
York Mellon, as Trustee (herein called the “Trustee,” which term includes any successor trustee under the Indenture), and reference is hereby made to the Indenture for a statement of the respective rights, limitations of rights,
duties and immunities thereunder of the Company, the Trustee, the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. Insofar as the provisions of the Indenture may conflict with the
provisions set forth on the face of this Security, the latter shall control for purposes of this Security. 
 This Security is one of the
series designated on the face hereof. References herein to “this series” mean the series designated on the face hereof. 

Payments under the Securities will be made without deduction or withholding for, or on account of, any and all present or future income, stamp
and other taxes, levies, imposts, duties, charges, fees, deductions or withholdings (“Taxes”) now or hereafter imposed, levied, collected, withheld or assessed by or on behalf of the United Kingdom or any political subdivision or
authority thereof or therein having the power to tax (each a “Taxing Jurisdiction”), unless such deduction or withholding is required by law. If any such Taxes are at any time required by a Taxing Jurisdiction to be deducted or
withheld, the Company will, subject to the exceptions and limitations set forth in Section 10.04 of the Indenture, pay such additional amounts of the principal of such Security and any other amounts payable on such Security (“Additional
Amounts”) as may be necessary in order that the net amounts paid to the Holder of any Security, after such deduction or withholding, shall equal the amounts of the principal of such Security and any other amounts payable on such Security
which would have been payable in respect of such Security had no such deduction or withholding be required. 
 If at any time the Company
determines that as a result of a change in or amendment to the laws or regulations of a Taxing Jurisdiction (including any treaty to which such Taxing Jurisdiction is a party), or a change in an official application or interpretation of such laws or
regulations (including a decision of any court or tribunal), either generally or in relation to any particular Securities, which change, amendment, application or interpretation becomes effective on or after the Original Issue Date in making any
payment of, or in respect of, the principal amount of the Securities, the Company would be required to pay any Additional Amounts with respect thereto, then the Securities will be redeemable upon not less than 35 nor more than 60 days’ notice
by mail, at any time thereafter, in whole but not in part, at the election of the Company as provided in the Indenture at a redemption price determined by the Calculation Agent in a manner reasonably calculated to preserve the relative economic
position of the Company and the Holders of Outstanding Securities. 
 (Reverse of Security continued on next page) 

 The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the
modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of a majority in
principal amount of the Securities at the time Outstanding of all series to be affected (considered together as one class for this purpose). The Indenture also contains provisions (i) permitting the Holders of a majority in aggregate principal
amount of the Securities at the time Outstanding of all series to be affected under the Indenture (considered together as one class for this purpose), on behalf of the Holders of all Securities of such series, to waive compliance by the Company with
certain provisions of the Indenture and (ii) permitting the Holders of a majority in aggregate principal amount of the Securities at the time Outstanding of any series to be affected under the Indenture (with each such series considered
separately for this purpose), on behalf of the Holders of all Securities of such series, to waive certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and
binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this
Security. 
 As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have any right to
institute any proceeding, judicial or otherwise, with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a
continuing Event of Default with respect to the Securities of this series, the Holders of not less than 25% in aggregate principal amount of the Securities of this series at the time Outstanding shall have made written request to the Trustee to
institute proceedings in respect of such Event of Default as Trustee and offered the Trustee reasonable indemnity against the costs, expenses and liabilities to be incurred in compliance with such request, and the Trustee shall not have received
from the Holders of a majority in principal amount of Securities of this series at the time Outstanding a direction inconsistent with such request, and shall have failed to institute any such proceeding, for 60 days after receipt of such notice,
request and offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder of this Security for the enforcement of any payment of principal hereof on or after the respective due dates expressed herein. 

(Reverse of Security continued on next page) 

 No reference herein to the Indenture and no provision of this Security or of the Indenture shall
alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of this Security as herein provided. 

As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Security is registrable in the Senior
Debt Security Register, upon surrender of this Security for registration of transfer at the office or agency of the Company in any place where the principal of this Security is payable, duly endorsed by, or accompanied by a written instrument of
transfer in form satisfactory to the Company and the Senior Debt Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing. Thereupon one or more new Securities of this series and of like tenor, of authorized
denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees. 
 This Security, and
any other Securities of this series and of like tenor, is issuable only in registered form without coupons in minimum denominations of $200,000 and integral multiples of $1,000 in excess thereof. As provided in the Indenture and subject to certain
limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this series and of like tenor of a different authorized denomination, as requested by the Holder surrendering the same.

 No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum
sufficient to cover any tax or other governmental charge payable in connection therewith. 
 Prior to due presentment of this Security for
registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Security be overdue, and neither
the Company, the Trustee nor any such agent shall be affected by notice to the contrary. 
 This Security and the Indenture shall be
governed by and construed in accordance with the laws of the State of New York.EX-10.1

the Board for each period for which he is so elected or appointed. 
 1.2. Acceptance. The Executive hereby accepts such
employment and agrees to render the services described above on an exclusive basis to the Company. During the Term, and consistent with Section 1.1, the Executive agrees to serve the Company faithfully and to the best of the Executive’s
ability and to use the Executive’s best efforts, skill and ability to promote the interests of the Company in a manner consistent with the Executive’s position. The Executive also agrees to devote the Executive’s entire business time,
energy and skill to such employment, except for vacation time, absence for sickness or similar disability, and time spent performing services for any charitable, religious or community organizations, so long as such services do not materially
interfere with the performance of the Executive’s duties hereunder or create a conflict of interest other than current board of director positions held by Executive and disclosed in Exhibit A. The Executive may not serve on the board of
directors of any other for-profit business or organization without the prior consent of the Board. In consideration for the substantial consideration provided for herein and as a condition to this Agreement, the Executive agrees to be bound by the
terms of the Non-Competition and Proprietary Information Agreement attached hereto as Exhibit B.

December 31 of the same year unless either the Company or the Executive notifies the other party in writing not later than November 1 of the prior year that the notifying party has elected not to extend the Term (“Notice of
Non-Renewal”), in which event the Term shall end on December 31 of such year. Notwithstanding the foregoing provisions of this Section 2, the Term shall terminate on the date the Executive’s employment is terminated as provided
in Section 4 (and, for the avoidance of doubt, such notification shall not preclude a termination of employment pursuant to Section 4 prior to the then scheduled expiration of the Term).

the Company’s standard payroll practices, at the initial annual rate of $1,000,000 (as adjusted in accordance with this Section 3.1, the “Base Salary”). The Executive’s Base Salary will be subject to annual review for
increase (but not decrease, unless such decrease is in connection with a similar percentage decrease in salary applicable to all senior executives at the Company) by the Compensation Committee of the Board (the “Committee”) and the Board
in accordance with the Company’s typical schedule for all senior executives, with future increases subject to the discretion of the Board based on performance. All payments of Base Salary or other compensation hereunder shall be less such

individual goals, shall otherwise only be conditioned upon the Executive remaining employed by the Company through the last 

  
 -2- 

 
business day of the fiscal year in which the award was earned; provided that nothing contained herein shall be construed to limit the Committee’s authority to adjust the Annual Bonus in
accordance with the Bonus Program. The Executive’s target Annual Bonus under the Bonus Program (the “Annual Bonus Target”) shall be no less than 150% of the Executive’s Base Salary for each fiscal year that ends during the Term
up to a maximum of 200% of the Annual Bonus Target. The actual amount of the Executive’s Annual Bonus for the Company’s 2014 fiscal year shall be prorated from the Effective Date through the end of fiscal year 2014, and further adjusted
based upon the achievement of the Company goals as set forth in the Bonus Program previously established by the Committee for fiscal year 2014 and of the individual goals, as determined by the Committee and approved by the Board after consultation
with the Executive. The actual amount of any Annual Bonus for subsequent years shall be determined by and in accordance with the terms of Company’s then-current Bonus Program. Payment of any Annual Bonus shall be made in a single lump sum cash
payment no later than the November 30 following the end of the applicable fiscal year in which the award was earned.

value shall be an option to purchase the Company’s common stock, subject to 5 year annual vesting. Such grants shall each be subject to all terms and conditions applicable to grants under the Equity Plan, shall be evidenced by grant agreements
in the form customarily used for Equity Plan grants to other named executive officers of the Company and shall be subject to the performance, payout and vesting conditions previously established by the Committee for fiscal year 2014, provided,
however, that such awards shall immediately vest (subject in the case of the performance stock units to the achievement of established ROIC targets) upon Executive’s death or Disability in accordance with the governing award agreement.
Commencing with fiscal year 2015, the Executive shall be eligible to receive additional grants under the Equity Plan or any successor plan in such amounts as the Committee may determine in its sole discretion. 

3.4. Sign-On Equity. In order to induce the Executive to accept employment with the Company and to replace the equity incentives
the Executive has forfeited from his prior employer, the Company will grant the Executive $10,000,000 in value (based on closing price of Company’s common stock on the Effective Date) of which (i) twenty-five percent (25%) of the
value shall consist of performance stock units that will vest subject to the achievement of the price target for the Company’s common stock on NASDAQ over a five (5) year period set forth in the governing award agreement, the stock price

shall consist of restricted stock units, subject to 4 year annual vesting; and (iii) fifty percent (50%) of the value will be an option to purchase the Company’s common stock, subject to 5 year annual vesting. The grant of the options
and restricted stock units referred to herein shall each be subject to all terms and conditions applicable to grants under the Equity Plan and shall be

3.5. Investment Opportunity. 

3.5.1 Purchased Shares Prior to December 31, 2014, the Executive may elect to purchase, on the market and during periods

RSUs described in Section 3.5.2. 
 3.5.2 Matching RSUs. As soon as practicable after the end of any month during which the

 7.1.
Governing Law; Jurisdiction and Venue. This Agreement shall be governed by and construed and enforced in accordance with the laws of the Commonwealth of Massachusetts applicable to agreements made between residents thereof and to be
performed entirely in Massachusetts. Any action brought by either party with respect to this Agreement, shall be brought and maintained only in the state or federal courts located in the Commonwealth of Massachusetts. Each party consents to personal
jurisdiction and venue in such courts, waives any right to file a motion based on forum non conveniens or any similar doctrine and agrees not to oppose any motion to transfer any such case to such courts. 

7.2. Headings. The section headings contained herein are for reference purposes only and shall not in any way affect the meaning
or interpretation of this Agreement. 
 7.3. Entire Agreement; Amendment. This Agreement sets forth the entire agreement and
understanding of the parties relating to the subject matter hereof, and supersedes all prior agreements, arrangements and understandings, written or oral, relating to the subject matter hereof; provided, however, that the Non-Competition and
Proprietary Information Agreement, Change of Control Agreement, Indemnification Agreement, and any outstanding option or other equity agreements by and between the Company and Executive shall be governed in accordance with the terms therein. No
representation, promise or inducement has been made by either party that is not embodied in this Agreement, and neither party shall be bound by or liable for any alleged representation, promise or inducement not so set forth herein. This Agreement
may be amended, modified, superseded, canceled, renewed or extended and the terms or covenants hereof may be waived, only by a written instrument executed by both of the parties hereto, or in the case of a waiver, by the party waiving compliance.
The failure of either party at any time or times to require performance of any provision hereof shall in no manner affect the right at a later time to enforce the same. No waiver by either party of the breach of any term or covenant contained in
this Agreement, whether by conduct or otherwise, in any one or more instances, shall be deemed to be, or construed as, a further or continuing waiver of any such breach, or a waiver of the breach of any other term or covenant contained in this
Agreement. 
 7.4. Assignability. 

7.4.1 Nonassignability by Executive. This Agreement, and the Executive’s rights and obligations hereunder, may not be

successor (whether direct or indirect, by purchase, merger, consolidation or otherwise) to all or substantially all of the business and/or assets of the Company to assume expressly and agree to perform this Agreement in the same manner and to the
same extent that the Company would be required to perform it if no such succession had taken place. Failure of the Company to obtain such assumption and agreement prior to the effectiveness of any such succession shall be a breach of this Agreement
and shall entitle the Executive to compensation from the Company in the same amount and on the same terms as the Executive would be entitled hereunder if the Executive had terminated his employment for Good Reason, except that for purposes of
implementing the foregoing, the date on which any such succession becomes effective shall be deemed the Termination Date. As used in this Agreement, the “Company” shall mean the Company as previously defined and any successor to its
business and/or assets as aforesaid which assumes and agrees to perform this Agreement by operation of law, or otherwise. 
 7.5.
Survival. The respective rights and obligations of the parties hereunder, including under Sections 4, 5 and 7, shall survive any termination of this Agreement or the expiration of the Term to the extent necessary to the intended
preservation of such rights and obligations.

arrangements or understandings, written or oral, that would prevent Executive from entering into this Agreement, would prevent Executive or restrict Executive in any way from rendering services to the Company as provided herein during the Term or
would be breached by the future performance by the Executive of the Executive’s duties hereunder. The Executive also represents and warrants that no fee, charge or 

  
 -12- 

 
expense of any sort is due from the Company to any third person engaged by the Executive in connection with Executive’s employment by the Company hereunder, except as disclosed in this
Agreement. 
 9. Code Section 409A Legal Requirement. 

9.1. Six Month Delay in Payment. Notwithstanding anything to the contrary in this Agreement, if the Executive is a
“specified employee” as defined and applied in section 409A of the Code as of the Executive’s Termination Date, then, to the extent any payment under this Agreement or any Company Arrangement constitutes deferred compensation (after
taking into account any applicable exemptions from section 409A of the Code, including those specified in Section 9.2) and to the extent required by section 409A of the Code, no payments due under this Agreement or any Company Arrangement may
be made until the earlier of: (i) the first day following the sixth month anniversary of the Executive’s Termination Date and (ii) the Executive’s date of death. 

9.2. Application of Exemptions. For purposes of section 409A of the Code, each “payment” (as defined by section 409A
of the Code) made under this Agreement shall be considered a “separate payment.” In addition, for purposes of section 409A of the Code, each such payment shall be deemed exempt from section 409A of the Code to the fullest extent possible
under the “short-term deferral” exemption of Treasury Regulation § 1.409A-1(b)(4), as well as any other applicable exemptions. 

9.3. Reimbursement and Offset Provisions. Reimbursement payments shall generally be made in accordance with applicable Company
policies; however, in no event will reimbursement payments be made later than the end of the year following the year in which the expense was incurred. The amounts eligible for reimbursement provided in one taxable year will not affect the amounts
eligible for reimbursement provided in any other taxable year, and the right to reimbursement will not be subject to liquidation or exchange for another benefit. Notwithstanding any other provision of this Agreement to the contrary, in no event
shall any payment that constitutes “non-qualified deferred compensation” under section 409A of the Code be subject to offset by any other amount unless otherwise permitted by section 409A. 

9.4. Interpretation and Administration of Agreement. To the maximum extent permitted by law, this Agreement shall be interpreted
and administered in such a manner that the payments to the Executive are either exempt from, or comply with, the requirements of section 409A of the Code.

NON-COMPETITION AND PROPRIETARY INFORMATION AGREEMENT 

THIS AGREEMENT (the “Agreement”), is made and entered into as of December 6, 2013, by and between Hologic, Inc., a

 Recitals 

WHEREAS, the Company and the Executive have entered into an Employment Agreement of even date herewith (the “Employment
Agreement”); and 
 WHEREAS, it is a condition of the execution of the Employment Agreement that this Agreement be
entered into and be incorporated by reference in the Employment Agreement as Exhibit A thereto; and 
 WHEREAS, the Executive will
receive substantial economic payments and benefits as a result of the Employment Agreement and his employment with the Company; and 

WHEREAS, in his capacity as Chief Executive Officer, President and member of the Board of Directors of the Company, Executive has had
and will continue to have access to the Company’s business activities, goodwill, business plans, personnel, financial status and other confidential and proprietary information including, but not limited to, existing and potential customers,
customer information, target market areas, potential and future products, methods, techniques and other information of and about the Company, all of which are of great value to the Company and which are not generally known and are confidential; and

 WHEREAS, terms not defined herein shall have the meaning ascribed to them in the Employment Agreement. 

Agreement 
 NOW,
THEREFORE, in consideration of the above-referenced premises and the mutual covenants and promises therein and herein contained, the receipt and sufficiency of which is acknowledged, and intending to be legally bound, it is hereby agreed by and
between the parties as follows: 
 1. Term. This Agreement shall commence upon the Effective Date of the Employment Agreement.

 2. Unique Position of Trust. 

(a) Executive acknowledges that the services he has heretofore rendered and will continue to render to the Company are of a special and
unusual character, with a unique value to the Company. Executive also acknowledges that he has held and holds a position of trust in which he has had and will continue to have broad access to all of the Company’s most sensitive Confidential
Information. 

  
 -16- 

 (b) For purposes of this Agreement, “Company” shall mean Hologic, Inc. and, any other
business entity that is either controlled by, controls, or under common control with Hologic, Inc. 
 (c) For purposes of this Agreement,
“Confidential Information” means all non-public information of and about the Company, including without limitation, business activities, business plans, legal affairs, personnel, existing and potential customers, customer information,
contracts and agreements with customers, contracts and agreements with suppliers, target market areas, product designs and plans, potential and future products, business methods and techniques, financial status, financial projections and forecasts,
regulatory matters, pending and proposed acquisitions, financings and joint ventures, intellectual property, trade secrets, proprietary technology, research and development data, computer networks and systems, software programs and code, databases,
manufacturing processes and specifications, know-how, operational and hiring matters, personnel policies, market studies and forecasts, competitive analyses, marketing programs, and sales and pricing information, regardless of the form in which such
information is stored. “Confidential Information” shall also include any Confidential Information of any client, investor, corporate partner, or joint venturer of the Company, or any other third party that the Company is required by
agreement to keep confidential. “Confidential Information” shall not, however, include information that Executive can demonstrate (a) has become publicly known through no act of the Executive, (b) has been rightfully received by
Executive from a third party not subject to any confidentiality agreement concerning such information or (c) has been independently developed by Executive without use of or reliance on Confidential Information or any violation of his
obligations under this Agreement. If a particular portion or aspect of Confidential Information becomes subject to any of the foregoing exceptions, all other portions or aspects of such information shall remain subject to all of the provisions of
this Agreement. 
 3. Protection of Company Confidential Information. 

(a) Executive shall not, while an employee of the Company, or following termination of his employment, directly or indirectly, use, disclose
or permit to be known, other than (i) as is reasonably required in the regular course of his duties on behalf of the Company, including disclosures to the Company’s advisors and consultants, (ii) as required by law (in which case
Executive shall give the Company prior written notice of such required disclosure) or (iii) with the prior written consent of the Company’s Board of Directors or Chief Executive Officer, to any person, firm or corporation any Confidential
Information. 
 (b) The Executive shall not remove from the Company’s premises, or make any copies of, Confidential Information, except
as necessary to perform or use in the course of legitimate Company business. The Executive agrees to return to the Company all Confidential Information and Company property, including all copies of it, in his possession or under his control,
(i) at any time upon the request of the Company, and (ii) without such a request at the termination of his employment by the Company. Upon the Company’s request, the Executive will furnish a written statement that he has returned all
Confidential Information and property. 

  
 -17- 

 4. Non-Competition Agreement.  

(a) In view of the unique value to the Company of the services of Executive, because of the Confidential Information of the Company entrusted
to or obtained by Executive, and as a material inducement to the Company to enter into the Employment Agreement, pursuant to which Executive will receive significant benefits as an executive officer and director of the Company, and for other good
and valuable consideration, Executive covenants and agrees that he shall not during the Term and for two years from the Termination Date (the “Restricted Period”), directly or indirectly, whether as an owner, partner, executive, director,
consultant, contractor, advisor, agent, employee, guarantor, surety or otherwise, or through any person, consult with or in any way aid or assist any person to engage or attempt to engage in any employment, consulting or other activity which
directly or indirectly competes with the business of the Company (the “Restricted Field”). Executive acknowledges that his participation in the conduct of any such business or activity alone or with any person other than the Company will
materially impair the business and prospects of the Company and the goodwill of the Company. Notwithstanding anything herein to the contrary, the Restricted Period shall be reduced to one (1) year from the Termination Date in the event the
Executive is entitled to benefits under Section 4.4.4 of the Employment Agreement. 
 (b) During the Restricted Period, Executive shall
not, directly or indirectly, on behalf of any party or person other than the Company, solicit (or assist or provide information in connection therewith) any then-customer of the Company (including customers where the Company’s products or
services are sold through distributors, resellers, licensees and the like) or prospective customer of the Company to provide any product, service, or business that is competitive with or substantially similar to any product, service, or business
then offered or planned to be offered by the Company, or to induce such then-customer or prospective customer to reduce or diminish the volume or level of their business with the Company. 

(c) During the Restricted Period, Executive shall not, directly or indirectly, on behalf of any party or person other than the Company,
solicit or induce (or assist or provide information in connection therewith) any then-current employee, or person who was an employee or officer of the Company within the previous six month period, to leave the employ of the Company. 

(d) Executive further acknowledges the national and international scope of the business of the Company, and that the limitations set forth in
this Agreement on his post-employment activities are reasonable and necessary to protect the business of the Company because of its scope and his access to Confidential Information. Executive further acknowledges that the consideration and benefits
that he will receive pursuant to the Employment Agreement are substantial enough that the limitations on his post-employment activities set forth in this Agreement will not cause significant hardship. 

(e) Nothing herein shall preclude Executive (i) from beneficially owning no more than two percent (2%) of the total outstanding
stock of a class of stock registered under the securities and Exchange Act of 1934, as amended or (ii) following the Termination Date, from accepting or providing advisory or consulting services to, or accepting employment with, a business that
may have a product or services in the Restricted Field; provided, however, that the Executive may not provide services to or be employed by, directly or indirectly, the division, 

  
 -18- 

 
subsidiary or line of business that competes, directly or indirectly, with the Company in the Restricted Field or otherwise engage in any activities that may involve the disclosure or use of
Confidential Information. 
 5. Disclosure and Assignment of Inventions. Executive shall promptly disclose to the Company any
invention, improvement, discovery, process, formula, method, work of authorship, or other intellectual property, whether or not patentable, and whether or not copyrightable, in the Company’s Restricted Field (collectively,
“Inventions”) made, conceived or first reduced to practice by Executive, either alone or jointly with others, during the term of Executive’s employment with the Company, whether or not such Inventions are made, conceived or
reduced to practice during working hours or using the Company’s data or facilities. Executive agrees that all Inventions created, made, or developed by him during the term of his employment with the Company are and shall be works made for hire
and are and shall be the exclusive property of the Company to use, publish, license, and otherwise exploit in its discretion. The Company shall own all of the rights, including without limitation all trade secrets, patents and copyrights, in,
arising or derived from, or related to any Inventions. In the event that any Inventions may not, by operation of law or otherwise, be a work made for hire, Executive hereby assigns, irrevocably and without any further consideration, the ownership
of, and all rights of patent and copyright in, such Inventions. During and after his employment and/or service with the Company ceases, the Executive shall execute any documents necessary to perfect the assignment of such Inventions to the Company
and to enable the Company to apply for, obtain and enforce patents and/or copyrights in any and all countries on such Inventions. Executive hereby irrevocably designates the Company’s General Counsel as Executive’s agent and attorney-in-fact to execute and file any such document and to do all lawful acts necessary to apply for and obtain patents and/or copyrights and to enforce the Company’s
rights under this Section 5. Any Invention relating to the business of the Company and disclosed by Executive within one year following the termination of his employment with the Company shall be deemed to fall within the provisions of this
Section 5 unless Executive shall prove that such Inventions were first conceived and reduced to practice after the date of termination of his employment. 

6. Remedies. Given the important nature of the services Executive will provide to the Company, the scope and nature of the
business of the Company and the sensitive nature of the information and functions Executive will have with the Company, Executive acknowledges that the limitations contained in Sections 3, 4 and 5 hereof are reasonable. Executive expressly
acknowledges that, in the event that any provision of Sections 3, 4 or 5 is breached, the Company will suffer injury that cannot be ascertained or remedied by monetary damages and will be irreparably harmed if the provisions of this Agreement are
not enforced. In the event of an actual or threatened breach by Executive of the provisions of Sections 3, 4 or 5, the Company shall be entitled to terminate any payments and provision of benefits that Executive may be entitled pursuant to the
Employment Agreement or otherwise, including the further exercise of any Equity Awards, and to entry of an injunction restraining Executive from such breach without any obligation to post bond. Nothing herein, however, shall be construed as
prohibiting the Company from pursuing any other remedies available to the Company for such breach or threatened breach, including the recovery of damages and reasonable attorneys’ fees and expenses, including paralegal fees, from Executive,
which Executive agrees the Company would be entitled to recover. If Executive violates any of the covenants contained in Sections 3, 4 or 5 the terms and the covenants violated shall be automatically extended to a like period of time

  
 -19- 

 
from the date on which Executive ceases such violation or from the date of entry by a court of competent jurisdiction of any order or judgment enforcing such covenant, whichever period is later.
To the extent permitted under applicable law, the Company may suspend any payments or benefits that Executive may be entitled pursuant to the Employment Agreement or otherwise for the duration of any period in which the Company reasonably determines
that Executive is in breach hereof. Executive further acknowledges and agrees that any breach of the covenants contained in Sections 3, 4 or 5 shall constitute a material breach of this Agreement entitling the Company to terminate this Agreement for
cause. The provisions of Sections 3, 4 and 5 and this Section 6 shall survive the termination of this Agreement. 
 7.
Notices. Any notice or other communication in connection with this Agreement shall be delivered in accordance with the notice provisions of Section 6.1 of the Employment Agreement. 

8. Injunction and Enforceability of Covenants. 

(a) Equitable Remedies Available. If Executive commits a breach, or threatens to commit a breach of any of the provisions of Sections
3, 4 or 5 hereof, the Company shall have the right and remedy to have the provisions of this Agreement specifically enforced by a court having equity jurisdiction in the Commonwealth of Massachusetts, it being acknowledged and agreed that any such
breach or threatened breach will cause irreparable injury to the Company and that money damages will not provide an adequate remedy to the Company. 

(b) Severability of Covenants. If any of the covenants contained in Sections 3, 4 or 5 hereof, or any part thereof, is hereafter
construed to be invalid or unenforceable, the same shall not affect the remainder of the covenant or covenants, which shall be given full effect without regard to the invalid portions. The covenants and restrictions contained in Sections 3, 4, and 5
of this Agreement are separate and independent of the obligations of the Employment Agreement and shall be fully valid and enforceable notwithstanding any breach or claimed breach of the Employment Agreement. 

(c) Carve-back of Scope or Duration. If any of the covenants contained in Sections 3, 4 or 5 hereof, or any part thereof, are held to
be unenforceable because of the scope or duration of such provision or the area covered thereby, the parties agree that the court making such determination shall have the power to reduce the scope, duration and/or area of such provision to the least
extent possible to render them enforceable and such provision, in its reduced form, shall thereafter be enforceable. 
 (d)
Jurisdiction. The parties hereto intend to and hereby confer jurisdiction to enforce the covenants contained in Sections 3, 4 or 5 hereof upon the state and federal courts sitting in the Commonwealth of Massachusetts. In the event that such a
courts shall hold any such covenant wholly unenforceable by reason of the breadth of scope or otherwise, it is the intention of the parties hereto that such determination not bar or in any way affect the Company’s right to the relief provided
above in the courts of any other states within the geographical scope of such other covenants having appropriate personal and subject matter jurisdiction over the parties, as to breaches of such covenants in such other respective jurisdictions, the
above covenants as they relate to each state being, for this purpose, severable into diverse and independent covenants. 

  
 -20- 

 9. Waiver of Breach. The waiver by either party of a breach of any provision of
this Agreement by the other party shall not operate or be construed as a waiver of any subsequent breach by the other party. 
 10.
Entire Agreement. The recitals hereto are hereby incorporated herein by this reference. This Agreement, together with the Employment Agreement attached hereto, constitutes the entire agreement of the parties concerning the subjects
contained herein and supersedes all prior or contemporaneous negotiations, representations and agreements, whether written or oral, between Executive and the Company with respect to the subject matter hereof, provided, however, that the superseding
of such agreements does not in any way affect the validity or effectiveness of the prior assignment by Executive of inventions. This Agreement may not be changed orally, but only by an agreement in writing signed by the party against whom
enforcement of any such change is sought. 
 11. Interpretation. The parties hereto acknowledge and agree that: (i) each
party and its counsel reviewed and negotiated the terms and provisions of this Agreement and have contributed to its revision; (ii) the rule of construction to the effect that any ambiguities are resolved against the drafting party shall not be
employed in the interpretation of this Agreement; and (iii) the terms and provisions of this Agreement shall be construed fairly as to all parties hereto and not in favor of or against any party, regardless of which party was generally
responsible for the preparation of this Agreement. 
 12. Binding Agreement and Governing Law. This Agreement shall be
binding upon the Executive and shall inure to the benefit of the Company and its successors in interest and assigns, and shall be construed in accordance with and governed by the laws of the Commonwealth of Massachusetts. 

13. Counterparts. This Agreement may be executed in multiple counterparts, each of which shall be deemed an original but all of
which together shall constitute one and the same instrument. 
 IN WITNESS WHEREOF, the parties hereto execute this Agreement as of
the date first written above.
