 -6- 

 6.2 Mitigation. The Executive shall not be required to mitigate the amount of any payment
provided for in this Agreement by seeking other employment or otherwise and no such payment shall be offset or reduced by the amount of any compensation or benefits provided to the Executive in any subsequent employment. 
 6.3 Other Severance Benefits. The severance pay and benefits provided for in Section 6.1(b) shall be in lieu of any other severance or
termination pay to which the Executive may be entitled under any Company severance or termination plan, program, practice or arrangement. The Executive's entitlement to any other compensation or benefits shall be determined in accordance with the
Company's employee benefit plans and other applicable programs, policies and practices then in effect. 
 7. Divestiture or Sale of
Division. Notwithstanding any other provision of this Agreement to the contrary, the termination of the Executive's employment with the Company in connection with the sale, divestiture or other disposition of a Subsidiary or
“Division” (as hereinafter defined) (or part thereof) shall not be deemed to be a termination of employment of the Executive for purposes of this Agreement; provided, however, in the event such sale, divestiture or other
disposition of a Subsidiary or Division, the Company obtains an express written agreement from such purchaser or acquiror as contemplated in Section 9.3. The Executive shall not be entitled to benefits from the Company under this Agreement as a
result of such sale, divestiture, or other disposition, except in the event of a subsequent termination of employment entitling Executive to a payment hereunder. “Division” shall mean a business unit or other substantial business operation
within the Company that is operated as a separate profit center, but that is not maintained by the Company as a separate legal entity. 
 8. Excise Tax Payments. 
 8.1 Notwithstanding anything contained in this Agreement to the contrary, to the
extent that the payments and benefits provided under this Agreement and benefits provided to, or for the benefit of, the Executive under any other Company plan or agreement (such payments or benefits are collectively referred to as the
“Payments”) would be subject to the excise tax (the “Excise Tax”) imposed under Section 4999 of the Internal Revenue Code of 1986, as amended (the “Code”), the Payments shall be reduced (but not below zero) if and
to the extent necessary so that no Payment to be made or benefit to be provided to the Executive shall be subject to the Excise Tax (such reduced amount is hereinafter referred to as the “Limited Payment Amount”). Unless the Executive
shall have given prior written notice specifying a different order to the Company to effectuate the Limited Payment Amount, the Company shall reduce or eliminate the Payments, by first reducing or eliminating those payments or benefits which are not
payable in cash and then by reducing or eliminating cash payments, in each case in reverse order beginning with payments or benefits which are to be paid the farthest in time from the “Determination” (as hereinafter defined). Any notice
given by the Executive pursuant to the preceding sentence shall take precedence over the provisions of any other plan, arrangement or agreement governing the Executive's rights and entitlements to any benefits or compensation. 
 8.2 An initial determination as to whether the Payments shall be reduced to the Limited Payment Amount pursuant to the Plan and the amount of such
Limited Payment Amount shall be made by an accounting firm at the Company's expense selected by the Company which 

  

 -7- 

 
is designated as one of the six largest accounting firms in the United States (the “Accounting Firm”). The Accounting Firm shall provide its
determination (the “Determination”), together with detailed supporting calculations and documentation, to the Company and the Executive within five (5) days of the Termination Date, if applicable, or such other time as requested by
the Company or by the Executive (provided the Executive reasonably believes that any of the Payments may be subject to the Excise Tax), and if the Accounting Firm determines that no Excise Tax is payable by the Executive with respect to a Payment or
Payments, it shall furnish the Executive with an opinion, at the Company's expense, reasonably acceptable to the Executive that no Excise Tax will be imposed with respect to any such Payment or Payments. Within ten (10) days of the delivery of
the Determination to the Executive, the Executive shall have the right to dispute the Determination (the “Dispute”). If there is no Dispute, the Determination shall be binding, final and conclusive upon the Company and the Executive
subject to the application of Section 8.3 below. 
 8.3 As a result of the uncertainty in the application of Sections 4999 and
28OG of the Code, it is possible that the Payments to be made to, or provided for the benefit of, the Executive either have been made or will not be made by the Company which, in either case, will be inconsistent with the limitations provided in
Section 8.1 (hereinafter referred to as an “Excess Payment” or “Underpayment”, respectively). If it is established pursuant to a final determination of a court, or an Internal Revenue Service (the “IRS”) proceeding
which has been finally and conclusively resolved, that an Excess Payment has been made, such Excess Payment shall be deemed for all purposes to be a loan to the Executive made on the date the Executive received the Excess Payment and the Executive
shall repay the Excess Payment to the Company, on demand (but not less than thirty (30) days after written notice is received by the Executive), together with interest on the Excess Payment at the “Applicable Federal Rate” (as defined
in Section 1274(d) of the Code) from the date of the Executive's receipt of such Excess Payment until the date of such repayment. In the event that it is determined by (i) the Accounting Firm, the Company (which shall include the position
taken by the Company, or together with its consolidated group, on its federal income tax return) or the IRS, (ii) pursuant to a determination by a court, or (iii) upon the resolution to the Executive's satisfaction of the Dispute, that an
Underpayment has occurred, the Company shall pay an amount equal to the Underpayment to the Executive within thirty (30) days of such determination or resolution, together with interest on such amount at the Applicable Federal Rate from the
date such amount would have been paid to the Executive until the date of payment. 
 8.4 The Company represents and warrants that this
Agreement and all payments and benefits associated with it are in compliance with Section 409A of the Internal Revenue Code. However, if the Company is found not to be in compliance with Section 409(A) in the future, and this noncompliance
results in any excise tax or penalty being born by you, the Company will fully reimburse you within thirty (30) days of any tax and/or penalty you may incur. Notwithstanding the above, in the event of a determination that any payment or benefit
associated with this Agreement is not compliant with the provisions of Section 409A of the Internal Revenue Code, the Company agrees that it will modify this Agreement to make it compliant with Section 409A and that it will make a good
faith effort to maintain the value of the payments and benefits under this Agreement. 
  

 -8- 

 8.5 Notwithstanding anything contained in this Agreement to the contrary, in the event that,
according to the Determination, an Excise Tax will be imposed on any Payment or Payments, the Company shall pay to the applicable government taxing authorities, as Excise Tax withholding, the amount of the Excise Tax that the Company has actually
withheld from the Payment or Payments. 
 9. Successors: Binding Agreement. 
 9.1 This Agreement shall be binding upon and shall inure to the benefit of the Company, and its Successors and Assigns, and the Company shall
require any Successors and Assigns to expressly assume 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 or assignment had taken place. 
 9.2 Neither this Agreement nor any right or interest hereunder shall be assignable or transferable by the Executive, his beneficiaries or legal
representatives, except by will or by the laws of descent and distribution. This Agreement shall inure to the benefit of and be enforceable by the Executive's personal representative. 
 9.3 In the event that a Subsidiary or Division (or part thereof) is sold, divested, or otherwise disposed of by the Company subsequent to or in
connection with a Change in Control and the Executive is offered employment by the purchaser or acquiror thereof, the Company shall require such purchaser or acquiror to expressly assume, and agree to perform, the Company's obligations under this
Agreement, in the same manner, and to the same extent, that the Company would be required to perform if no such acquisition or purchase had taken place. 
 10. Arbitration. Any dispute, controversy or claim arising out of or relating to this Agreement, or the breach, termination or invalidity hereof, (collectively, a “Claim”) shall be settled by
arbitration pursuant to the rules of the American Arbitration Association and by a panel of three arbitrators, two of which will be chosen by each party and one agreed to by both parties. If the parties are unable to agree on the arbitrator within
thirty (30) days of one party giving the other party written notice of intent to arbitrate a Claim, the American Arbitration Association shall appoint an arbitrator with such qualifications to conduct such arbitration. The decision of the
arbitrator in any such arbitration shall be conclusive and binding on the parties. Any such arbitration shall be conducted in Boston, Massachusetts, unless the Executive consents to a different location. 
 11. Injunctive Relief. If the Executive commits a breach or is about to commit a breach, of any of the provisions of this Agreement, the
Company shall have the right to have the provisions of this Agreement specifically enforced by any court having equity jurisdiction without being required to post bond or other security and without having to prove the inadequacy of the available
remedies at law, it being acknowledged and agreed that any such breach or threatened breach will cause irreparable injury to the Company and that money damages will may not provide an adequate remedy to the Company. In addition, the Company may take
all such other actions and remedies available to it under law or in equity and shall be entitled to such damages as it can show they have sustained by reason of such breach. 
  

 -9- 

 12. Tax Treatment; Tax Withholding. The Company and the Executive hereby acknowledge and
agree that any Retention Bonus payable hereunder and issuance of Company common stock pursuant to the Restricted Stock Unit Agreement shall be treated and reported by the Company and the Executive as additional compensation for services rendered and
as ordinary income. The Executive also acknowledges and agrees that the Company may withhold from any Retention Bonus, issuance of Company’s common stock pursuant to the Restricted Stock Unit Agreement or severance payment such amounts as may
be required to satisfy all federal, state and local withholding and employment tax obligations. 
 13. General Provisions.

 13.1 No Special Employment Rights. No provision of this Agreement shall grant or confer upon, or shall be construed to grant
or confer upon, the Executive any right with respect to the continuation of his employment by the Company or to otherwise affect in any respect the terms and conditions of such employment except to the extent expressly provided hereunder.

 Exhibit B 
 EMPLOYEE INTELLECTUAL PROPERTY RIGHTS 
 AND NON-COMPETITION AGREEMENT 

In order to induce Hologic, Inc., a Delaware corporation (the “Company”), to employ me initially or to continue my employment, as the case
may be, and in consideration of its doing so, I hereby agree as follows: 
  

	1.	Definitions. 

 When used in this Agreement, the
terms specified below have the meanings indicated. Terms defined elsewhere in this Agreement have the meanings specified there. 
 “Company” means the Company and, any other business entity that is either controlled by, controls, or under common control with the Company. 
 “Confidential Information” means Information, whether it is or is not recorded or embodied in or on Material, that is not a Trade Secret but that is identified to me as being confidential to the
Company. 
 “Information” means all information concerning technical, administrative, financial, manufacturing, or marketing
activities, including, without limitation, design, manufacturing, and procurement specifications; engineering and manufacturing data; manufacturing processes, techniques, and know-how; formulas; information-processing processes or programs;
techniques, and know-how; research and development plans; trade secrets; marketing plans and strategies; customer names, employee names and responsibilities, cost and financial data, and other data. 
 “Invention” means any discovery, invention, improvement, process, formula, or technique, whether patentable or not. 
 “Material” means any physical embodiment of Information, regardless of whether I or someone else created it, including, without
limitation, drawings, specifications, recording media for machine information-processing systems (such as disks, ROMs, and tapes that contain Information), documentation of all types, contracts, reports, manuals, lists, quotations, proposals,
correspondence, notebooks, and samples. 
 “Trade Secret” means any Information, whether it is or is not recorded or embodied
on or in a Material, that is not readily available from either the Company or another source without restrictions on its use and disclosure and whose use by Company gives it an opportunity to obtain an advantage over its then-current or potential
competitors that do not use it.

either alone or with others, (a) either in the course of performing work for Company or at Company’s expense, or (b) that results from tasks assigned to me by Company, or (c) whose creation ordinarily would be associated with my
then current responsibilities as an employee of the Company. If I am identified as an inventor in any application for any United States or foreign patent where the Invention (i) is claimed to have been made, conceived, or reduced to practice
during the first year after termination of my employment by the Company and (ii) would have been a Proprietary Invention if it occurred before the termination of my employment, then that Invention shall be rebuttably presumed to be a
Proprietary Invention. 
 “Trade Secret Material” means Material that contains Trade Secrets. 
  

	2.	Acknowledgment of Relationship of Trust. 

 I realize
that my employment by the Company involved a relationship of confidence and trust between me and the Company with respect to its intellectual property rights, which include patents, trade secrets, copyrights, and trademarks, and that, as part of my
employment, I am expected to contribute to the Company by creating and protecting those rights. I understand that the Company’s competitive position depends on its ability to develop, utilize, and keep control over those intellectual property
rights, and I will develop and protect those rights as provided below, or as otherwise reasonably requested in writing. 
  

	3.	Non-disclosure of Trade Secrets and Confidential Information. 

 (a) At all times, both during my employment by the Company and afterward, I will keep in confidence, and will not disclose, any Trade Secrets to anyone, and will not transfer any Trade Secret Material to anyone,
including employees of Company, except as authorized by the Company. I will use any Trade Secrets and Trade Secret Material to which I have access only in the course of my work for the Company and for its benefit and will not appropriate it for the
benefit of myself or any other person. During my employment by Company I will comply with its then-current procedures for the protection of Trade Secrets and Trade Secret Material. In the event of any inconsistency between those procedures and the
requirements of this Agreement, the more stringent procedures or requirements will apply. 
 (b) At all times, both during my employment by
the Company and afterward, I will keep in confidence and will not disclose or transfer any Confidential Information to any person other than an employee of Company, except as authorized by the Company, and I will not appropriate confidential
information for the benefit of myself or any other person.

order to avoid disputes over the application of paragraph 7 below, I attach to this Agreement, as Exhibit A, a complete list of all Inventions I made, conceived, or first reduced to practice, alone or jointly with others, prior to my employment by
Employer, that are not described in a publication or patent application in existence on the Effective Date of this Agreement, and that I want to exclude from the effect of this Agreement. If no such list is attached to this Agreement, I represent
that I will have no such Inventions as of the Effective Date. 
  

	6.	Disclosure of Inventions. 

 I will disclose to the
Company promptly (a) any Proprietary Inventions and (b) any Inventions of which I am aware that are made, conceived, or first reduced to practice by others performing services for Employer. 
  

	7.	Assignment of Proprietary Inventions. 

 All
Proprietary Inventions shall be the exclusive property of the Company, and the Company shall be the owner of any patents and other rights related to Proprietary Inventions. Accordingly, I hereby assign and convey to the Company all of my right,
title, and interest in and to any Proprietary Inventions. 
  

	8.	Cooperation and Further Assurances. 

 I will help
the Company, at its expense, obtain and enforce patents on Proprietary Inventions in any countries it selects, and I will execute any related documents, including, without limitation, application papers for letters patent, assignments, affidavits
and oaths of facts within my knowledge, and assignments of my right, title, and interest in and to Proprietary Inventions and related patents to the Company or its designee. I will do any other things the Company requests to convey to, or vest in,
the Company the rights, titles, benefits, and privileges intended to be conveyed. My obligation under this paragraph shall continue after the termination of my employment, subject to the Company’s compensating me at a reasonable rate for time
actually spent by me at Employer’s request on such help after termination of employment. 
  

 -18- 

	9.	Prior Agreements. 

 I attach to this Agreement, as
Exhibit B, a complete list of prior agreements with any other person related to intellectual property rights or which restricts in any way my employment by the Company. I represent that my performance of all the terms of this Agreement and as an
employee of the Company will not breach any other agreement, including any employment, confidentiality, non-competition, or other agreement,. I will not enter into any agreement either written or oral in conflict with this Agreement. 
  

	10.	Works in Authorship. 

 (a) I acknowledge that all
works of authorship (including, without limitation, works of authorship that contain software program code) I produce during and within the scope of, my employment by the Company, whether they are or are not created on the Company’s premises or
during hours in which I am supposed to be rendering services to the Company, are works made for hire and are the property of the Company, and that copyrights in those works of authorship are the property of the Company. If for any reason it appears
that the Company is not the author of any such work of authorship for copyright purposes, I hereby expressly assign all of my rights in and to that work to the Company and agree to sign any instrument of specific assignment requested. 
 (b) I will use reasonable efforts to avoid including in any work of authorship I produce within the scope of my employment any material that then is
created by, or on behalf of, any person other than the Company. I will inform the Company of any material created by or on behalf of any other person that I recommend be included in a work of authorship. 
  

	11.	Information or Material of Others. 

 I will not
disclose to Company, or use in Company’s business, or Information or Material relating to the business of any other person and intended by that person not to be disclosed to Company. 
  

	12.	Full Time and Best Efforts. 

 I will devote my full
time during the time I am expected to work, and my best efforts, to Company’s business to the exclusion of all other business activities. In addition, while I am employed by the Company, I will not, directly or indirectly, either by myself or
in conjunction with others, be engaged or interested in, or affiliated with, or organize or help to organize, or aid or assist in any manner any business similar to or competitive with Company, except that mere ownership of no more than one percent
(1%) of the capital stock of a corporation whose stock is registered under Section 12 or Section 13 of the Securities Exchange Act of 1934 is not so barred. I agree to fully comply with all published Company policies and procedures as
they may be amended from time to time, and to always conduct myself in accord with the highest ethical, moral, and legal standards. 
  

 -19- 

	13.	Non-competition. 

 During the course of my
employment and for two (2) years after termination thereof for any reason, I will not, directly or indirectly, either by myself or in conjunction with others, be engaged or interested in, or affiliated with or organize or help to organize, or
aid or assist in any manner, any business competitive with the products and services then offered or planned to be offered by the Company, in the United States or elsewhere, except that I understand that mere ownership of no more than two percent
(2%) of the total outstanding stock of a publicly held corporation is not so barred. During this same period, I shall not on behalf of any party or person other than the Company, solicit or induce (or assist or provide information in connection
therewith) any (i) then-customer or prospective customer of the Company for any product or service competitive with any product or service then offered or planned to be offered by the Company, or (ii) then-current employee (except for my
personal assistant) to leave the employ of the Company. I recognize that the foregoing limitations are reasonably required for the adequate protection of the Company's business and do not preclude me from pursuing my livelihood. However, if any such
foregoing limitation is found by a court to be unenforceable for any reason, said limitation shall be interpreted to extend only to the maximum extent enforceable. I agree to inform any new employer or associate of this Agreement and to provide it
with a copy. 
 Both the employee and the Company agree that they will discuss at the point of separation, a reasonable alternative to the
non-competition portion of this agreement. The intent here would be 1.) not to prevent the employee from seeking gainful employment and 2.) To protect the company’s proprietary and confidential information as it pertains to that for which the
employee was aware of or was directly involved in. Upon agreement at that time by both parties, the Non-Competition section of this agreement would be so waived. 
 For purposes of this Agreement, I will not be deemed, directly or indirectly, either by myself or in conjunction with others, to be engaged or interested in, or affiliated with or organize or help to organize, or aid
or assist in any manner, any business competitive with the products and services then offered, planned to be offered by the Company, in the United States or elsewhere subject to the following: 
  

	 	(i)	the business competing with the Company derives less than ten percent (10%) of its total annual revenues from products and services then under development or offered by the
Company in the United States or elsewhere; and 

  

	 	(ii)	I do not have any relationship with the portion, subsidiary or division of the competing business engaged in selling or developing the same products and services as the Company.

  

	14.	Enforcement. 

 I acknowledge that my employment by
Company imposes on me a duty to act solely for the benefit of Company. In addition to any other remedies Company has available to it, Company is entitled, at its election, to recover from me (a) the value of anything belonging to Company I use,
or transfer, in breach of that duty, and (b) any benefit I 

  

 -20- 

 
receive as a result of violating that duty of loyalty, or the value of that benefit or its proceeds, and Company also shall be entitled to recover from me
the amount of damages it suffered as a result. 
  

	15.	Successors and Assigns. 

 This Agreement shall be
binding upon me and my heirs, executors, assigns, and administrators and shall inure to the benefit of Company and its successors and assigns. 
  

	16.	Miscellaneous. 

 This Agreement contains the entire
and only agreement between me and Company with respect to the subject matter hereof, and no modification shall be binding on me or Company unless in writing and signed by me and an officer of the Company. My obligations under this Agreement shall
survive termination of my employment for any reason, and regardless of whether said termination is or is alleged to be a breach of this or any other Agreement I may have with the Company. This Agreement shall be governed by, subject to, and
construed according to the laws of the Commonwealth of Massachusetts. This Agreement is executed under seal. 
  

	17.	Effective Date. 

 This Agreement shall be effective
as of the date set forth below.

 Exhibit C 
 Cytyc Change of Control Agreement 
  

 -22-Amended and Restated Change of Control Agreement with Patrick J. Sullivan

 Exhibit 10.12 
 EXECUTION COPY 
 AMENDED AND RESTATED 
 CHANGE OF CONTROL AGREEMENT 
 AMENDED AND RESTATED CHANGE OF CONTROL AGREEMENT by and
between Hologic, Inc., a Delaware corporation (the “Company”), and Patrick J. Sullivan (the “Executive”), dated as of August 17, 2007 (the “Agreement”). This Agreement amends and restates in its entirety that
certain Change of Control Agreement dated as of May 20, 2007 (the “Original Agreement”) to further clarify certain provisions of the Original Agreement. 
 WHEREAS, upon the Closing Date (as such term is defined in the Merger Agreement) and pursuant to that certain Agreement and Plan of Merger by and among the Company, Nor’easter Corp. and Cytyc Corporation
(“Cytyc”) dated as of May 20, 2007 (the “Merger Agreement”), the stockholders of Cytyc will own over 50% of the outstanding shares of the Company; 
 WHEREAS, subject to and conditioned upon the completion of the Merger, commencing as of the Closing Date (as defined in the Merger Agreement, such date
to be sometimes referred to herein as the “Effective Time” of this Agreement), the Company desires that the Executive will serve as Executive Chairman and executive officer of the Company; and 
 WHEREAS, subject to and conditioned upon the consummation of the Merger (as such term is defined in the Merger Agreement), the Board of Directors of the
Company (the “Board”), has determined that it is in the best interests of the Company and its shareholders to assure that the Company will have the continued dedication of the Executive, notwithstanding the possibility, threat, or
occurrence of a Change of Control (as defined below) of the Company. The Board believes it is imperative to diminish the inevitable distraction of the Executive by virtue of the personal uncertainties and risks created by a pending or threatened
Change of Control and to encourage the Executive’s full attention and dedication to the Company currently and in the event of any threatened or pending Change of Control, and to provide the Executive with compensation and benefits arrangements
upon a Change of Control which ensure that the compensation and benefits expectations of the Executive will be satisfied and which are competitive with those of other corporations; and 
 WHEREAS, in the event that the Merger Agreement is terminated, then this Agreement shall become null and void ab initio and be of no further force
and effect. 
 NOW, THEREFORE, in consideration of the mutual covenants and agreements hereinafter set forth, the parties hereto, each
intending to be legally bound, do hereby agree as follows: 
 1. Certain Definitions. 
 (a) The “Effective Date” shall be the first date during the Change of Control Period (as hereinafter defined) on which a Change of Control
occurs. Anything in this Agreement to the contrary notwithstanding, if the Executive’s employment 

 
with the Company is terminated prior to the date on which a Change of Control occurs, and it is reasonably demonstrated that such termination of employment
(1) was at the request of a third party who has taken steps reasonably calculated to effect the Change of Control or (2) otherwise arose in connection with or in anticipation of the Change of Control, then for all purposes of this
Agreement the “Effective Date” shall mean the date immediately prior to the date of such termination of employment. 
 (b) The
“Change of Control Period” is the period commencing on the date hereof and ending on the second anniversary of such date; provided, however, that commencing on the date one year after the date hereof, and on each annual anniversary of such
date (such date and each annual anniversary thereof is hereinafter referred to as the “Renewal Date”), the Change of Control Period shall be automatically extended without any further action by the Company or the Executive so as to
terminate three years from such Renewal Date; provided, however, that if the Company shall give notice in writing to the Executive, at least 60 days prior to the Renewal Date, stating that the Change of Control Period shall not be extended, then the
Change of Control Period shall expire three years from the last effective Renewal Date. 
 2. Change of Control. For the purpose of
this Agreement, a “Change of Control” shall mean: 
 (a) The acquisition by any one person, or more than one person
acting as a group, of stock of the Company (the “Company Stock”) that, together with Company Stock held by such person or group, constitutes more than 50% of the total fair market value or total voting power of the Company Stock; provided,
however, that if any one person, or more than one person acting as a group, is considered to own more than 50% of the total fair market value or total voting power of the Company Stock, the acquisition of additional Company Stock by the same person
or persons shall be construed as not triggering a Change of Control; and provided further, however, that an increase in the percentage of Company Stock owned by any one person, or persons acting as a group, as a result of a transaction in which the
Company acquires its Company Stock in exchange for property shall be treated as an acquisition of Company Stock for purposes of this Section 2(a); 
 (b) The acquisition by any one person, or more than one person acting as a group, on a single date or during the 12-month period ending on the date of the most recent acquisition by such person or persons, ownership
of Company Stock possessing 30% or more of the total voting power of the Company Stock; provided, however, that if any one person, or more than one person acting as a group, already has satisfied this requirement, the acquisition of additional
Company Stock by the same person or persons shall be construed as not triggering a Change of Control; and provided further, however, that an increase in the 

  

 -2- 

 
percentage of Company Stock owned by any one person, or persons acting as a group, as a result of a transaction in which the Company acquires its Company
Stock in exchange for property shall be treated as an acquisition of Company Stock for purposes of this Section 2(b); 
 (c) A majority of the Company’s Board members is replaced during any 12-month period by directors whose appointment or election is not endorsed by a majority of the Company’s Board members before the date of the appointment or
election; or 
 (d) The acquisition by any one person, or more than one person acting as a group, on a single date or during
the 12-month period ending on the date of the most recent acquisition by such person or persons, assets from the Company that have a total gross fair market value equal to more than 40% of the total gross fair market value of all of the assets of
the Company immediately prior to such acquisition or acquisitions; provided, however that there is no Change of Control under this Section 2(d) when there is a transfer to an entity that is controlled by the Company’s shareholders
immediately after the transfer. For purposes of the immediately preceding clause, there is no Change of Control under this Section 2(d) if the assets are transferred to 
  

	 	(i)	a shareholder of the Company (immediately before the asset transfer) in exchange for or with respect to its Company Stock; 

  

	 	(ii)	an entity, 50% or more of the total value or voting power of which is owned, directly or indirectly, by the Company; 

  

	 	(iii)	a person, or more than one person acting as a group, that owns, directly or indirectly, 50% or more of the total value or total voting power of the Company Stock; or

  

	 	(iv)	an entity, at least 50% of the total value or voting power of which is owned, directly or indirectly, by a person described in (iii) above. 

 For purposes of (i) through (iv) above, a person’s status generally is determined immediately after the transfer of the assets. 

For purposes of this Section 2, persons shall not be considered as acting as a “group” solely because they purchase or
own Company Stock at the same time, or as a result of the same public offering. However, persons shall be considered as acting as a “group” if they are owners of a corporation that enters into a merger, consolidation, purchase or
acquisition of stock, or similar business transaction with the Company. If a person, including an entity, owns stock in the Company 

  

 -3- 

 
and another corporation that enter into a merger, consolidation, purchase or acquisition of stock, or similar transaction, such shareholder shall be
considered to be acting as a “group” with other shareholders only with respect to the ownership in that corporation before the transaction giving rise to the change and not with respect to the ownership interest in the Company. 

(e) Nothing herein shall supersede or effect the rights that the Executive may have under the Change of Control Agreement, as amended,
entered into by and between the Executive and Cytyc with an effective date of July 23, 2003 (the “Cytyc Change of Control Agreement”); provided, however, that the Executive acknowledges that the benefits provided for under
Section 2(a)(i)(B) therein were paid out upon consummation of the Merger. 
 3. Employment Period. Subject to and conditioned
upon the consummation of the Merger and subject to the terms and conditions hereof, the Company hereby agrees to appoint Executive as Executive Chairman of the Board of Directors and to retain the Executive in its employ as an executive officer, and
the Executive hereby agrees to accept such retention by the Company, for the period commencing on the Effective Date, and ending on the last day of the twenty-fourth month following the month in which the Effective Date occurs (the “Employment
Period”). 
 4. Terms of Employment. (a) Position and Duties. (i) During the Employment Period, (A) the
Executive’s position (including status, offices, titles and reporting requirements), authority, duties and responsibilities shall be the same as those described in Exhibit A of the Amended and Restated Retention Agreement executed by and
between the Company and Executive dated August 17, 2007 (the “Retention Agreement”) and (B) the Executive’s services shall be performed at the location of the Company’s corporate headquarters or any office or location
less than 35 miles from such location. 
 (ii) During the Employment Period, and excluding any periods of vacation and sick leave to which
the Executive is entitled, the Executive agrees to devote his full business time to the business and affairs of the Company and, to the extent necessary to discharge the responsibilities assigned to the Executive hereunder, to use the
Executive’s reasonable best efforts to perform faithfully and efficiently such responsibilities. During the Employment Period it shall not be a violation of this Agreement for the Executive to (A) serve on corporate, civic or charitable
boards or committees, (B) deliver lectures, fulfill speaking engagements or teach at educational institutions and (C) manage personal investments, so long as such activities do not significantly interfere with the performance of the
Executive’s responsibilities as an employee of the Company in accordance with this Agreement. It is expressly understood and agreed that to the extent that any such activities have been conducted by the Executive prior to the Effective Date,
the continued conduct of such activities (or the conduct of activities similar in nature and scope thereto) subsequent to the Effective Date shall be permitted. 
  

 -4- 

 (b) Compensation. 
 (i) Base Salary. During the Employment Period, the Executive shall receive an annual base salary (“Annual Base Salary”) of Seven Hundred Thousand Dollars ($700,000.00). During the Employment Period,
the Annual Base Salary shall be reviewed at least annually and shall be increased at any time and from time to time as shall be substantially consistent with increases in base salary awarded in the ordinary course of business to other peer
executives of the Company and its affiliated companies. Any increase in Annual Base Salary shall not serve to limit or reduce any other obligation to the Executive under this Agreement. Annual Base Salary shall not be reduced after any such increase
and the term Annual Base Salary as utilized in this Agreement shall refer to Annual Base Salary as so increased. As used in this Agreement, the term “affiliated companies” includes any company controlled by, controlling or under common
control with the Company. Annual Base Salary shall be payable in accordance with the Company’s normal payroll practices, but shall be paid at least monthly. 
 (ii) Annual Bonus. In addition to Annual Base Salary, the Executive shall be awarded, for each fiscal year of the Company during the Employment Period, an annual bonus (the “Annual Bonus”) in cash at
least equal to the greater of (a) the average (annualized for any fiscal year consisting of less than twelve full months or with respect to which the Executive has been employed by the Company or Cytyc for less than twelve full months) bonus
(the “Average Annual Bonus”) paid or payable to the Executive by the Company and its affiliated companies or Cytyc, as applicable, in respect of the three fiscal years immediately preceding the fiscal year in which the Effective Date
occurs, (b) the Annual Bonus paid for the fiscal year of the Company (if applicable, by Cytyc) immediately preceding the Effective Date, or (c) the maximum target bonus determined in accordance with the terms of the Company’s or
Cytyc’s, as applicable, bonus plan for senior executives for the fiscal year immediately preceding the Effective Date (the “Target Bonus”). Each such Annual Bonus shall be paid no later than the 15th day of the third month of the
fiscal year next following the fiscal year for which the Annual Bonus is awarded. In no event shall the calculation of the Annual Bonus, Average Annual Bonus and Special Bonus (as defined in Section 4(b)(iv)) include: any bonuses deferred by
the Company, as applicable, or retention bonus or severance benefits provided under the Retention Agreement between the Executive and Company. Notwithstanding anything herein to the contrary, any portion of Annual Base Salary or Annual Bonus
electively deferred by the Executive pursuant to a qualified or a non-qualified plan including, but not limited to, the Hologic, Inc. Supplemental Executive Retirement Plan (“SERP”) shall be included in determining the Annual Base Salary,
Annual Bonus and the Average Annual Bonus. If the fiscal year of any successor to this Agreement, as described by Section 11(c) herein, is different than the Company’s fiscal year at the time of the Change of Control, then the Executive
shall be paid (i) the Annual Bonus that would have been paid upon the end of Company’s fiscal year ending after the Change of Control, and (ii) a pro-rata Annual Bonus for any months of service performed following the end of the
Company’s fiscal year, but prior to the first day of the successor’s fiscal year immediately following the Change of Control. The Annual Bonuses thereafter shall be based on the successor’s first full fiscal year beginning after the
Change of Control and successive fiscal years thereafter. 
 (iv) Special Bonus. In addition to Annual Base Salary and Annual Bonus
payable as hereinabove provided, if the Executive remains employed with the Company and/or its affiliated companies through the first anniversary of the Effective Date, the Company shall 

  

 -5- 

 
pay to the Executive a special bonus (the “Special Bonus”) in recognition of the Executive’s services during the crucial one-year transition
period following the Change of Control in cash equal to the sum of (A) the Executive’s Annual Base Salary and (B) the greater of (x) the Annual Bonus paid or payable (annualized for any fiscal year consisting of less than twelve
full months or for which the Executive has been employed for less than twelve full months) to the Executive for the most recently completed fiscal year of the Company during the Employment Period, if any, and (y) the greater of (i) the
Average Annual Bonus, (ii) the Annual Bonus paid for the fiscal year immediately preceding the Effective Date, or (iii) the Target Bonus (such greater amount hereafter referred to as the “Highest Annual Bonus”). Anything in this
Agreement to the contrary notwithstanding, if the Executive’s employment is terminated under Section 6(d) herein prior to the first anniversary of the Effective Date, then the Company shall pay the Executive the Special Bonus as if he was
employed on the first anniversary of the Effective Date. The Special Bonus shall be paid no later than 30 days following the first anniversary of the Effective Date or, if earlier, the Date of Termination. 
 (v) Incentive, Savings and Retirement Plans. In addition to Annual Base Salary and Annual Bonus payable as hereinabove provided, the Executive
shall be entitled to participate during the Employment Period in all incentive, savings and retirement plans, practices, policies and programs applicable to other peer executives of the Company and its affiliated companies, but in no event shall
such plans practices, policies and programs provide the Executive with incentive, savings and retirement benefits opportunities, in each case, less favorable, in the aggregate, than the most favorable of those provided by Company or, if applicable,
Cytyc, for the Executive under such plans, practices, policies and programs as in effect at any time during the one-year immediately preceding the Effective Date, or, if more favorable to the Executive, those provided generally at any time after the
Effective Date to other peer executives of the Company and its affiliated companies. 
 (vi) Welfare Benefit Plans. During the
Employment Period, the Executive and/or the Executive’s family, as the case may be, shall be eligible for participation in and shall receive all benefits under welfare benefit plans, practices, policies and programs provided by the Company and
its affiliated companies (including, without limitation, medical, prescription, dental, disability, salary continuance, employee life, group life, accidental death and travel accident insurance plans and programs) and applicable to other peer
executives of the Company and its affiliated companies, but in no event shall such plans, practices, policies and programs provide benefits which are less favorable, in the aggregate, than the most favorable of such plans, practices, policies and
programs of the Company in effect at any time during the one-year period immediately preceding the Effective Date, or, if more favorable to the Executive, those provided generally at any time after the Effective Date to other peer executives of the
Company and its affiliated companies. 
 (vii) Expenses. During the Employment Period, the Executive shall be entitled to receive
prompt reimbursement for all reasonable expenses incurred by the Executive upon submission of appropriate accountings in accordance with the most favorable policies, practices and procedures of the Company and its affiliated companies in effect at
any time during the one-year period immediately preceding the Effective Date or, if more favorable to the Executive, as in effect at any time thereafter with respect to other peer executives of the Company and its affiliated companies. 

 

 -6- 

 (viii) Fringe Benefits. During the Employment Period, the Executive shall be entitled to fringe
benefits in accordance with the most favorable plans, practices, programs and policies of the Company and its affiliated companies in effect at any time during the one-year period immediately preceding the Effective Date or, if more favorable to the
Executive, as in effect at any time thereafter with respect to other peer executives of the Company and its affiliated companies. 
 (ix)
Office and Support Staff. During the Employment Period, the Executive shall be entitled to an office or offices of a size and with furnishings and other appointments, and to exclusive personal secretarial and other assistance, at least equal
to the most favorable of the foregoing provided to the Executive by Company at any time during the one-year period immediately preceding the Effective Date or, if more favorable to the Executive, as provided at any time thereafter with respect to
other peer executives of the Company and its affiliated companies. 
 (x) Vacation. During the Employment Period, the Executive shall
be entitled to paid vacation in accordance with the most favorable plans, policies, programs and practices of the Company and its affiliated companies as in effect at any time during the one-year period immediately preceding the Effective Date or,
if more favorable to the Executive, as in effect at any time thereafter with respect to other peer incentives of the Company and its affiliated companies. 
 (xi) Out-Placement. If the Executive is terminated without Cause or resigns for Good Reason (both as defined herein), then the Company shall provide the Executive with outplacement services through Crenshaw
Associates, Inc. (or a comparable executive search firm of the Executive’s choice and within his sole discretion) or in the alternative, reimburse the Executive within fifteen (15) days of the Date of Termination for executive outplacement
services with cash in an amount typically provided by Company to other similarly situated executive officers upon an involuntary termination. 
 5. Termination of Employment. (a) Death or Disability. The Executive’s employment shall terminate automatically upon the Executive’s death during the Employment Period. If the Company determines in good faith
that the Disability of the Executive has occurred during the Employment Period (pursuant to the definition of “Disability” set forth below), it may give to the Executive written notice in accordance with Section 13(b) of this
Agreement of its intention to terminate the Executive’s employment. In such event, the Executive’s employment with the Company shall terminate effective on the 30th day after receipt of such notice by the Executive (the “Disability
Effective Date”), provided that, within the 30 days after such receipt, the Executive shall not have returned to full-time performance of the Executive’s duties. For purposes of this Agreement, “Disability” means the absence of
the Executive from the Executive’s duties with the Company on a full-time basis for 180 consecutive business days as a result of incapacity due to mental or physical illness which is determined to be 

  

 -7- 

 
total and permanent by a physician selected by the Company or its insurers and acceptable to the Executive or the Executive’s legal representative (such
agreement as to acceptability not to be withheld unreasonably). 
 (b) Cause. The Company may terminate the Executive’s
employment during the Employment Period for “Cause”. For purposes of this Agreement, “Cause” means (i) any fraudulent act or acts intended to result in substantial harm or loss to the Company or any of its subsidiaries;
(ii) material violation of the Company’s, or any of its subsidiaries’, Code of Conduct, and other Company Codes of Conduct or policies and procedures that are applicable to the Executive; or (iii) the conviction of the Executive
of a felony involving moral turpitude. The Company shall provide the Executive with 30 days written notice of any determination of Cause and provide the Executive, for a period of 30 days following such notice, with the opportunity to appear before
the Board, with or without legal representation, to present arguments and evidence on his behalf and following such presentation to the Board, the Executive may only be terminated for Cause if the Board by a vote of not less than 75% of the
independent directors (determined in accordance with the corporate governance listing standards of the Nasdaq National Market and the applicable rules and regulations of the Commission) determining that his actions did, in fact, constitute for
Cause. 
 (c) Good Reason. The Executive’s employment may be terminated during the Employment Period by the Executive for Good
Reason. For purposes of this Agreement, “Good Reason” means: 
 (i) A material reduction in the Executive’s
Annual Base Salary; 
 (ii) A material diminution in the Executive’s authority, duties (including removal from the
Company’s Board of Directors) and responsibilities as Executive Chairman of the Company as in effect 90 days prior to the executive’s Notice of Termination to the Company; 
 (iii) A material change in the geographic location at which the Executive must perform services, other than a move to Bedford,
Massachusetts; or 
 (iv) Any other action or inaction that constitutes a material breach by the Company of a term or
condition of this Agreement, including, for this purpose, a material breach of the Retention Agreement. 
 Provided, however, that no Good
Reason shall exist if the Executive has not given written notice to the Company within ninety (90) days of the initial existence of the Good Reason condition(s) and until the Company has had thirty (30) days to cure such event after the
date on which the Executive gives the Company written notice specifying such event in specific detail before such event permits the Executive to terminate his employment for Good Reason. 
  

 -8- 

 (d) Notice of Termination. Any termination by the Company for Cause or by the Executive for Good
Reason shall be communicated by Notice of Termination to the other party hereto given in accordance with Section 13(b) of this Agreement. For purposes of this Agreement, a “Notice of Termination” means a written notice which
(i) indicates the specific termination provision in this Agreement relied upon, (ii) to the extent applicable, sets forth in reasonable detail the facts and circumstances claimed to provide a basis for termination of the Executive’s
employment under the provision so indicated and (iii) if the Date of Termination (as defined below) is other than the date of receipt of such notice, specifies the termination date (which date shall be not more than fifteen days after the
giving of such notice). The failure by the Executive or the Company to set forth in the Notice of Termination any fact or circumstance which contributes to a showing of Good Reason or Cause shall not waive any right of the Executive or the Company
hereunder or preclude the Executive or the Company from asserting such fact or circumstance in enforcing the Executive’s or the Company’s rights hereunder. 
 (e) Date of Termination. “Date of Termination” means the date of receipt of the Notice of Termination or any later date specified therein, as the case may be; provided however, that (i) if the
Executive’s employment is terminated by the Company other than for Cause, death or Disability, the Date of Termination shall be the date on which the Company notifies the Executive of such termination and (ii) if the Executive’s
employment is terminated by reason of death or Disability, the Date of Termination shall be the date of death of the Executive or the Disability Effective Date, as the case may be. 
 6. Obligations of the Company upon Termination. 
 (a) Death. If the Executive’s employment is terminated by reason of the Executive’s death during the Employment Period, this Agreement shall terminate without further obligations to the
Executive’s legal representatives under this Agreement, other than for (i) payment of the sum of the following amounts: (A) the Executive’s Annual Base Salary through the Date of Termination to the extent not theretofore paid,
(B) the product of (I) the Highest Annual Bonus and (II) a fraction, the numerator of which is the number of days in the current fiscal year of the Company through the Date of Termination, and the denominator of which is 365, (C) the
Special Bonus, if due to the Executive pursuant to Section 4(b)(iv), to the extent not theretofore paid, and (D) any accrued and unpaid Annual Bonus amounts, compensation or vacation pay, in each case, to the extent not yet paid by the
Company (the amounts described in subparagraphs (A), (B), (C) and (D) are hereafter referred to as “Accrued Obligations” and shall be paid to the Executive’s estate or beneficiary, as applicable, in a lump sum in cash within
30 days of the Date of Termination), (ii) any other benefits or compensation payable under any employee benefit plan in accordance with the applicable plans’ terms (but in no event later than the 15th day of the third month of the calendar
year following the calendar year in which the death occurs), including, without limitation, any non-qualified plan or SERP; (iii) for the remainder of the Employment Period, or such longer period as any plan, program, practice or policy may
provide, the Company shall continue benefits to the Executive and/or the Executive’s family at least equal to those which would have been provided in accordance with the applicable plans, programs, practices and policies described in
Section 4(b)(v) and (vi) of this Agreement and the Cytyc Change in Control Agreement, other than any plans that constitute (or would if payments extended into a 

  

 -9- 

 
subsequent taxable year of the Executive) nonqualified deferred compensation plans within the meaning of Section 409A of the Code, or as if the
Executive’s employment had not been terminated in accordance with the most favorable plans, practices, programs or policies of the Company and its affiliated companies as in effect and applicable generally to other peer executives and their
families during the one year period immediately preceding the Effective Date or, if more favorable to the Executive, as in effect at any time thereafter with respect to other peer executives of the Company and its affiliated companies and their
families (such continuation of such benefits for the applicable period herein set forth shall be hereinafter referred to as “Welfare Benefit Continuation”) (for purposes of determining eligibility of the Executive for retiree benefits
pursuant to such plans, practices, programs and policies, the Executive shall be considered to have remained employed until the end of the Employment Period and to have retired on the last day of such period), and (iv) payment to the
Executive’s estate or beneficiary, as applicable, in a lump sum in cash within 30 days of the Date of Termination of an amount equal to the sum of the Executive’s Annual Base Salary and the Highest Annual Bonus. Subject to the provisions
of Section 9 hereof, but, otherwise, anything herein to the contrary notwithstanding, the Executive’s family shall be entitled to receive benefits at least equal to the most favorable benefits provided by the Company and any of its
affiliated companies to surviving families of peer executives of the Company and such affiliated companies under such plans, programs, practices and policies relating to family death benefits, if any, as in effect with respect to other peer
executives and their families at any time during the one year period immediately preceding the Effective Date or, if more favorable to the Executive and/or the Executive’s family, as in effect on the date of the Executive’s death with
respect to other peer executives of the Company and its affiliated companies and their families. 
 (b) Disability. If the
Executive’s employment is terminated by reason of the Executive’s Disability during the Employment Period, this Agreement shall terminate without further obligations to the Executive, other than for (i) payment of the Accrued
Obligations (which shall be paid in a lump sum in cash within 30 days of the Date of Termination), (ii) the timely payment and provision of the Welfare Benefit Continuation, and (iii) payment to the Executive in a lump sum in cash within
30 days of the Date of Termination of an amount equal to the sum of the Executive’s Annual Base Salary and the Highest Annual Bonus. In addition, the Company shall transfer to the Executive the insurance policy written with respect to the
Executive under the Company’s Group Term Life Insurance Policy for Executive Officers and the right to the full cash surrender value thereof. Subject to the provisions of Section 9 hereof, but, otherwise, anything herein to the contrary
notwithstanding, the Executive shall be entitled after the Disability Effective Date to receive disability and other benefits at least equal to the most favorable of those provided by the Company and its affiliated companies to disabled executives
and/or their families in accordance with such plans, programs, practices and policies relating to disability, if any, as in effect with respect to other peer executives and their families at any time during the one year period immediately preceding
the Effective Date or, if more favorable to the Executive and/or the Executive’s family, as in effect at any time thereafter with respect to other peer executives of the Company and its affiliated companies and their families. 
 (c) Cause, Other than for Good Reason. If the Executive’s employment shall be terminated by the Company for Cause or by the Executive other
than for Good Reason (and other 

  

 -10- 

 
than by reason of his death or Disability) during the Employment Period, this Agreement shall terminate without further obligations to the Executive other
than the obligation to pay to the Executive Annual Base Salary through the Date of Termination. In such case, such amounts shall be paid to the Executive in a lump sum in cash within 30 days of the Date of Termination. 
 (d) Good Reason; Other Than for Cause or Disability. If, during the Employment Period, the Company shall terminate the Executive’s employment
other than for Cause, death or Disability, or if the Executive shall terminate employment under this Agreement for Good Reason (as such terms are defined herein, except as noted below): 
 (i) the Company shall pay to the Executive in a lump sum in cash within 30 days after the Date of Termination the aggregate of the
following amounts: 
 A. all Accrued Obligations; and 
 B. the Special Bonus, to the extent not previously paid or accrued (for purposes of clarification, i.e., not included in Accrued
Obligations), as calculated in accordance with Section 4(b)(iv) herein; 
 (ii) the Company shall timely pay and provide
the Welfare Benefit Continuation; provided, however, that if the Executive becomes reemployed with another employer and is eligible to receive medical or other welfare benefits under another employer provided plan, the medical or other welfare
benefits described herein shall be secondary to those provided under such other plan during such applicable period of eligibility; 
 (iii) the Company shall transfer to the Executive the insurance policy written with respect to the Executive under the Company’s Group Term Life Insurance Policy for Executive Officers and the right to the full cash surrender value
thereof; and 
 (iv) In the event of a termination for “Good Reason” or termination without “Cause” as
such terms are defined in the Cytyc Change of Control Agreement during the twenty-four months following the Closing Date, then the Company shall provide any benefits or payments provided to Executive under the Cytyc Change of Control Agreement,
including, but not limited to, all benefits under Sections 2(a)(i)(A), 2(a)(ii), 2(a)(iii), 2(a)(iv), Section 3 and Section 15, subject to Section 4 with respect to execution of a mutual release in good faith; provided, however, that
in no event will Executive be entitled to a payment under Section 2(a)(i)(B), which Executive acknowledges he is to receive upon the consummation of the Merger. 
  

 -11- 

 (e) Change of Control Payment. Upon a Change of Control, the Company shall pay the Executive the
following: 
 (i) a lump sum amount in cash within 30 days after the Effective Date equal to the (such amount shall be
hereinafter referred to as the “Change of Control Payment”) to the product of (X) three (3) multiplied by the sum of (i) (Y) the Annual Base Salary for the fiscal year immediately preceding the Effective Date and
(ii) Highest Annual Bonus; and 
 (ii) notwithstanding any other provisions to the contrary contained herein or in any
option agreement, restricted stock agreement or other equity compensation agreement, between the Company and the Executive, or any stock option, restricted stock or other equity compensation plans sponsored by the Company, unless such agreement or
plan expressly references and supersedes this Agreement, then all unvested options, restricted stock or stock appreciation rights which Executive then holds to acquire securities from the Company, shall be immediately and automatically exercisable
as of the Effective Date, and the Executive shall have the right to exercise any such options or stock appreciation rights for a period of one year after the Date of Termination; provided, however, that this acceleration of vesting shall not apply
to the restricted stock units issued to Executive pursuant to the Retention Agreement, which shall continue to vest in accordance with the terms therein. 
 7. Non-exclusivity of Rights. Except as provided in Section 6, nothing in this Agreement shall prevent or limit the Executive’s continuing or future participation in any benefit, bonus, incentive or
other plans, programs, policies or practices, provided by the Company or any of its affiliated companies and for which the Executive may qualify, nor shall anything herein limit or otherwise affect such rights as the Executive may have under any
other agreements with the Company or any of its affiliated companies. Amounts which are vested benefits or which the Executive is otherwise entitled to receive under any plan, policy, practice or program of the Company or any of its affiliated
companies at or subsequent to the Date of Termination shall be payable in accordance with such plan, policy, practice or program except as explicitly modified by this Agreement. 
 8. Full Settlement. (a) The Company’s obligation to make the payments provided for in this Agreement and otherwise to perform its
obligations hereunder shall not be affected by any set-off, counterclaim, recoupment, defense or other claim, right or action which the Company may have against the Executive or others. In no event shall the Executive be obligated to seek other
employment or take any other action by way of mitigation of the amounts payable to the Executive under any of the provisions of this Agreement and, except as provided in Section 6(d)(ii), such amounts shall not be reduced whether or not the
Executive obtains other employment. The Company agrees to pay promptly as incurred, to the full extent permitted by law, all legal fees and expenses which the Executive may reasonably incur as a result of any contest (regardless of the outcome
thereof) by the Company, the Executive or others of the validity or enforceability of, or liability under, any provision of this Agreement or any guarantee of performance thereof (including as a result of any contest by the Executive about the
amount of any payment pursuant to this Agreement, unless a court of competent jurisdiction determines that the Executive made such effort in bad faith), plus in each case interest at the rate of 12% per annum compounded annually. 
  

 -12- 

 (b) If there shall be any dispute between the Company and the Executive (i) in the event of any
termination of the Executive’s employment by the Company, whether such termination was for Cause, or (ii) in the event of any termination of employment by the Executive, whether Good Reason existed, then, unless and until there is a final,
nonappealable judgment by a court of competent jurisdiction declaring that such termination was for Cause or that the determination by the Executive of the existence of Good Reason was not made in good faith, the Company shall pay all amounts, and
provide all benefits, to the Executive and/or the Executive’s family or other beneficiaries, as the case may be, that the Company would be required to pay or provide pursuant to Section 6(d) as though such termination were by the Company
without Cause, or by the Executive with Good Reason; provided, however, that the Company shall not be required to pay any disputed amount pursuant to this paragraph except upon receipt of an undertaking by or on behalf of the Executive to repay all
such amounts to which the Executive is ultimately adjudged by such court not to be entitled. 
 9. 280G Protection. 
 (a) If any amounts payable under, or benefits resulting from, this Agreement or any other plan or other compensation are subject to the excise tax imposed
under Internal Revenue Code Section 4999 (the “Code”) on “excess parachute payments”, the Accounting Firm (as defined below) will in good faith compute the excise tax imposed under Code Section 4999 (the “Excise
Tax”) and Company shall pay that amount (the “Gross-Up Payment”) to the Executive, including any federal, state, local and excise taxes imposed on the foregoing payment under this Agreement assuming the Executive is in the highest
applicable marginal tax rate. The effect of such calculation will be to provide the Executive with a payment under this Agreement that is economically equivalent to the payment he would have received but for the imposition of the excise tax. The
calculations under this Section 9 will be made in a manner consistent with the requirements of Code Sections 280G and 4999, as in effect at the time the calculations are made. 
 (b) All determinations required to be made under this Section 9 shall be made by the Company’s auditing firm immediately preceding the
Effective Date, unless such firm shall be the accounting firm of the individual, entity or group effecting the Change of Control or any affiliate of the Company at the Date of Termination, in which case such determinations shall be made by an
accounting firm of national standing agreed to by the Company and the Executive, or, if the Company does not so agree within 10 days of the Date of Termination, such an accounting firm shall be selected by the Executive (the “Accounting
Firm”) which shall provide detailed supporting calculations both to the Company and the Executive within 15 business days of the date such firm is selected or such earlier time as is requested by the Company and an opinion to the Executive that
he has substantial authority not to report any Excise Tax on his Federal income tax return with respect to any Agreement Payments. Any such determination by the Accounting Firm shall be binding upon the Company and the Executive. Within five
business days of the determination by the Accounting Firm as to the Reduced Amount, the Company shall pay to or distribute to or for the benefit of the Executive such amounts as are then due to the Executive under this Agreement. The Gross-Up
Payment shall be paid to the Executive at the earliest possible time after receiving notice from the Executive, but not later than by the end of 

  

 -13- 

 
the calendar year in which the taxes are paid to the government, or if an audit or a tax dispute related to the Gross-Up Payment occurs, by the end of the
calendar year after the year in which the disputed taxes are paid (or the year after the year in which such an audit or dispute is concluded, if not taxes are paid.) 
 (c) As a result of the uncertainty in the application of Section 280G of the Code at the time of the initial determination by the Accounting Firm hereunder, it is possible that Gross-Up Payments will have been
made by the Company which should not have been made (“Overpayment”) or that additional Agreement Payments which will not have been made by the Company could have been made (“Underpayment”), in each case, consistent with the
calculations required to be made hereunder. In the event that the Accounting Firm, based upon the assertion of a deficiency by the Internal Revenue Service against the Executive which the Accounting Firm believes has a high probability of success
determines that an Overpayment has been made, any such Overpayment paid or distributed by the Company to or for the benefit of the Executive shall be treated for all purposes as a loan ab initio to the Executive which the Executive shall
repay to the Company together with interest at the applicable Federal rate provided for in Section 7872(f)(2) of the Code. In the event that the Accounting Firm, based upon controlling precedent or other substantial authority, determines that
an Underpayment has occurred, any such Underpayment shall be promptly paid by the Company to or for the benefit of the Executive together with interest at the rate of 12% per annum compounded annually. 
 10. Confidential Information. The Executive shall hold in a fiduciary capacity for the benefit of the Company all secret or confidential
information, knowledge or data relating to the Company or any of its affiliated companies, and their respective businesses, which shall have been obtained by the Executive during the Executive’s employment by the Company or any of its
affiliated companies and which shall not be or become public knowledge (other than by acts by the Executive or representatives of the Executive in violation of this Agreement). After termination of the Executive’s employment with the Company,
the Executive shall not, without the prior written consent of the Company or as may otherwise be required by law or legal process, communicate or divulge any such information, knowledge or data to anyone other than the Company and those designated
by it. In no event shall an asserted violation of the provisions of this Section 10 constitute a basis for deferring or withholding any amounts otherwise payable to the Executive under this Agreement. 
 11. Successors. (a) This Agreement is personal to the Executive and without the prior written consent of the Company shall not be assignable
by the Executive otherwise than by will or the laws of descent and distribution. This Agreement shall inure to the benefit of and be enforceable by the Executive’s legal representatives. 
 (b) This Agreement shall inure to the benefit of and be binding upon the Company and its successors and assigns. 
 (c) The Company will require any 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 

  

 -14- 

 
the same extent that the Company would be required to perform it if no such succession had taken place. The Company shall provide written evidence to the
Executive to document compliance with the foregoing sentence within ten (10) business days of the Effective Date. As used in this Agreement, “Company” shall mean the Company as hereinbefore 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. In addition, the Executive shall be entitled, upon exercise of any outstanding stock options or stock appreciation rights of the
Company, to receive in lieu of shares of the Company’s stock, shares of such stock or other securities of such successor as the holders of shares of the Company’s stock received pursuant to the terms of the merger, consolidation or sale.

 12. Compliance With Section 409A of the Internal Revenue Code. The Company covenants that it shall use its best efforts to
ensure that this Agreement and all payments and benefits associated with it are in compliance with Section 409A of the Code. However, if the Company is found not to be in compliance with Section 409A in the future, and this non compliance
results in any excise tax or penalty being borne by Executive, the Company will fully reimburse the Executive within thirty (30) days for any tax and/or penalty that he may incur. Notwithstanding the above, in the event of a determination that
any payment or benefit associated with this Agreement is not compliant with the provisions of Section 409A of the Code, the Company agrees that it will modify this Agreement, and the Executive agrees that he shall consent to such modification,
to make this Agreement compliant with Section 409A and that it shall maintain the value of the payments and benefits under this Agreement. Under no circumstances shall any provision of this Agreement be construed as preventing the Company from
modifying this Agreement, on or before December 31, 2007, or such other compliance deadlines as may be published by the Internal Revenue Service from time to time, to make this Agreement compliant with Section 409A. 
 13. Miscellaneous. (a) This Agreement shall be governed by and construed in accordance with the laws of the Commonwealth of Massachusetts,
without reference to principles of conflict of laws. The captions of this Agreement are not part of the provisions hereof and shall have no force or effect. This Agreement may not be amended or modified otherwise than by a written agreement executed
by the parties hereto or their respective successors and legal representatives. 
 (b) All notices and other communications hereunder shall
be in writing and shall be given by hand delivery to the other party or by registered or certified mail, return receipt requested, postage prepaid, addressed as follows:

Federal, state or local taxes as shall be required to be withheld pursuant to any applicable law or regulation.

between the Company and Executive shall remain in full force and effect and if the Company’s separation policy or the Retention Agreement would provide
greater benefits to the Executive than this Agreement, then the Executive may elect to receive benefits under the Company’s separation policy or Retention Agreement in lieu of the benefits provided hereunder, provided that such election
complies with the applicable requirements of Section 409A of the Code. Nothing herein shall affect the application of the Company’s separation policy and/or Retention Agreement in lieu of the benefits provided hereunder. Nothing herein
shall affect the application of the Company’s separation policy prior to the Effective Date. 
 (g) The Executive and the Company
acknowledge that, except as may otherwise be provided under any other written agreement between the Executive and the Company, the employment of the Executive by the Company is “at will” and may be terminated by either the Executive or the
Company at any time. Moreover, if prior to the Effective Date, the Executive’s employment with the Company terminates, then the Executive shall have no further rights under this Agreement. Notwithstanding anything contained herein, if, during
the Employment Period, the Executive shall terminate employment with the Company other than for Good Reason, the Executive shall have no liability to the Company.
