Agreement, (i) the Company shall be required to give the Executive at least six months notice of the termination of the Executive’s employment other than for Cause, and (ii) the Executive is permitted to give six months notice of
termination for Good Reason (as measured from the date notice is first given by

Executive’s employment by the Company without Cause, effective prior to the expiration of the Term of this Agreement. Notwithstanding anything to the contrary in this Agreement, the Company may relieve the Executive of all of his duties and
responsibilities hereunder and may relieve the Executive of authority to act on behalf of, or legally bind, the Company at any time after providing the Executive of Notice of Termination; provided, however, that any such action by the Company shall

accordance with the terms of such Equity Award. 
 1.19 “Voting Stock” means the then outstanding shares of
capital stock of the Company generally entitled to vote for the election of directors. For purposes of this Agreement, the reference to a percentage of Voting Stock shall be deemed to reference the voting power of such stock. 
 2. Employment and Duties. 
 (a) Title. Upon the execution of this Agreement, the Employee initially shall be employed as the Chairman of the Board and an executive officer of the Company. Subject to the terms and conditions
set forth herein, including any applicable notice provision, during and after the Term the Executive shall at all times be an “at will” employee. 
 (b) Duties. During the Term 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

Term, the Executive shall report directly to the Company’s Board of Directors and/or Chief Executive Officer as determined by

  

 -5-

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 and directorships are in compliance with the Company’s policies and procedures and do not otherwise interfere or conflict with the performance of his duties and responsibilities to the Company. The Executive further agrees to comply
with the Company’s policies and procedures as they may be applicable to him (including without limitation, as an employee, executive officer or director) as such policies and procedures may be modified from time to time. 
 3. Initial Compensation. Commencing on the date hereof, the Executive’s base salary (“Base Salary”) shall be
$725,000 per annum, payable on the same basis as payable to other executive officers of the Company. The Base Salary shall be subject to adjustment (either increase or decrease), at the discretion of the Compensation Committee. In addition, subject
to the terms of the applicable plan, the Executive shall be eligible to participate in the Company’s (a) short-term incentive plan or other annual bonus program provided to other officers of the Company and (b) Supplemental Executive

Executive remains employed as an executive officer on a full time basis, during the Company’s 2010 and 2011 fiscal year, the Executive’s target percentage of Base Salary for participation in the Company’s Short-Term Incentive Plan as
may then be in effect, if any, shall be 85%. In addition for the Company’s 2010 fiscal year the Executive shall be granted an annual equity incentive award, in the form of stock options and restricted stock units, in accordance with the

	 	(b)	If the Executive shall be terminated as an employee of the Company (1) by the Company without Cause, or by reason of Executive’s disability or death; or

	 	(iii)	any Retention Bonus that has not yet been paid; 

  

	 	(iv)	continue to provide, at the Company’s cost, group medical coverage to the Executive and his dependents on terms substantially similar to coverage provided to other
senior executives of the Company for period of six (6) months following the Termination Date; 

  

	 	(v)	 notwithstanding any other provisions to the contrary contained in any Equity Award agreement between the Company and the Executive, or any equity
compensation plans sponsored by the Company, from and after the Effective Date through the Termination Date, the Company shall vest the Executive in each Equity Award that was outstanding and unvested as of the Effective Date (but not any Equity
Award granted after the Effective Date) in equal

  

 -7- 

	 	 
monthly installments over the remaining vesting term of such Equity Award (measured from the Effective Date), but not less than would have otherwise vested under the Equity Award without regard
to this provision, provided that on any Termination Date the number of shares vested shall be rounded up to the nearest whole number (such that by way of example, (A) the Executive’s unvested Restricted Stock Units (“RSUs”)
covering 160,000 shares that otherwise vest by their terms on January 16, 2011 shall vest in monthly installments of 11,428.57 RSUs (160,000/14) on the 16th of each month commencing December 16, 2009, such that if the Termination Date is June 16, 2010 80,000 of
such RSU’s will be vested (11,428.57 x 7) and (B) the Executive’s unvested RSUs covering 231,000 shares that were issued on November 13, 2008 and otherwise vest by their terms in four equal annual installments of 57,750 RSUs on
November 13 of each year thereafter shall vest, after the vesting of 57,750 RSU’s on November 13, 2009, in equal monthly installments of 4,812.5 RSU’s (57,750/12) on the 13th of each month commencing December 13, 2009, such that if the Termination Date is June 13, 2010
33,688 of the remaining RSU’s will be vested (4,812.5 x 7)); and 

  

	 	(vi)	notwithstanding any other provisions to the contrary contained in any Equity Award agreement between the Company and the Executive, or any equity compensation plans
sponsored by the Company, unless such agreement or plan expressly references and supersedes this Agreement or the remaining term thereof, the Executive shall have the right to exercise any Equity Award that is then vested (including pursuant to
clause (c) below) for a period of the longer of (x) one (1) year from the Termination Date, or (y) the date such Equity Award would otherwise terminate by its terms; provided however, that the term of such Equity Award shall in
no event be extended beyond the remaining term of the award (determined without regard to any early termination provisions relating to termination of the Executive). 

  

	 	(c)	 If the Executive shall be terminated as an employee of the Company (1) by the Company without Cause, or by reason of Executive’s disability
or death; or (2) by the Executive for Good Reason, in each case where Notice of Termination is provided within three years following a Change of Control (or in anticipation of a Change of Control), then in addition to the

  

 -8- 

	 	 
benefits set forth in clauses (b)(i)-(vi) above, notwithstanding any other provisions to the contrary contained in any Equity Award agreement between the Company and the Executive, or any
equity compensation plans sponsored by the Company, unless such agreement or plan expressly references and supersedes this Agreement, all unvested Equity Awards which Executive then holds shall be immediately vested as of the Termination Date.

 8.2 Deemed Resignation. Upon termination of Executive’s employment for any reason or no
reason, including with or without Cause or for Good Reason, whether by the Company or by Executive, and unless the Board otherwise expressly determines, Executive agrees that he automatically shall have been deemed to have resigned from all
positions as an officer, director and employee of the Company or any subsidiaries or affiliates thereof without any further action on the part of the Executive. In connection therewith, simultaneously with the execution and delivery of this
Agreement, the Executive shall deliver a resignation letter in the form attached hereto as Exhibit B, which shall become effective, at the sole discretion of the Board, at any time from or after the Termination Date. 
 8.3 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. 
 8.4 Other Severance Benefits. The severance pay and benefits provided for in Section 8.1 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 (whether written or unwritten) 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. 
 9. 280G Excise Tax. The provisions of this Section 9 shall supersede any other provisions of this Agreement. 
 9.1 In the event that the Executive shall become entitled to payment and/or benefits provided by this Agreement or any other amounts
in the “nature of compensation” (whether pursuant to the terms of this Agreement or any other plan, arrangement or agreement with the Company, any person whose actions result in a change of ownership or effective control covered by
Section 280G(b)(2) of the Code or any person affiliated with the Company or such person) as a result of such change in ownership or effective control (collectively the “Company Payments”), and such Company Payments will be subject to
the tax (the “Excise Tax”) imposed by Section 4999 of the Code (and any similar tax that may hereafter be imposed by any taxing authority) the Company shall pay to the Executive the greater of the following, whichever gives the
Executive the highest net after-tax amount (after taking into account federal, state, local and social security taxes at the maximum marginal rates): (1) the Company Payments or (2) one dollar less than the amount of the Company Payments
that would subject the Executive to the Excise Tax. In the event that the Company Payments are required to be reduced pursuant to the foregoing sentence,

  

 -9- 

 
then the Company Payments shall be reduced as mutually agreed between the Company and the Executive or, in the event the parties cannot agree, in the following order (1) any lump sum
severance based on Base Salary or Annual Bonus, (2) any other cash amounts payable to the Executive, (3) any benefits valued as parachute payments; and (4) acceleration of vesting of any equity. 
 9.2 For purposes of determining whether any of the Company Payments will be subject to the Excise Tax and the amount of such Excise
Tax, (x) the Company Payments shall be treated as “parachute payments” within the meaning of Section 280G(b)(2) of the Code, and all “parachute payments” in excess of the “base amount” (as defined under Code
Section 280G(b)(3) of the Code) shall be treated as subject to the Excise Tax, unless and except to the extent that, in the opinion of the Company’s independent certified public accountants appointed prior to any change in ownership (as
defined under Section 280G(b)(2) of the Code) or tax counsel selected by such accountants or the Company (the “Accountants”) such Company Payments (in whole or in part) either expressly do not constitute “parachute
payments,” represent reasonable compensation for services actually rendered within the meaning of Section 280G(b)(4) of the Code in excess of the “base amount” or are otherwise not subject to the Excise Tax, and (y) the
value of any non-cash benefits or any deferred payment or benefit shall be determined by the Accountants. All determinations hereunder shall be made by the Accountants who shall provide detailed supporting calculations both to the Company and the
Executive at such time as requested by the Company or the Executive. If the Accountants determine that payments under this Agreement must be reduced pursuant to this paragraph, they shall furnish the Executive with a written opinion to such effect.
The determination of the Accountants shall be final and binding upon the Company and the Executive. 
 9.3 In the event
of any controversy with the Internal Revenue Service (or other taxing authority) with regard to the Excise Tax, the Executive shall permit the Company to control issues related to the Excise Tax (at its expense), provided that such issues do not
potentially materially adversely affect the Executive, but the Executive shall control any other issues. In the event the issues are interrelated, the Executive and the Company shall in good faith cooperate so as not to jeopardize resolution of
either issue, but if the parties cannot agree the Executive shall make the final determination with regard to the issues. In the event of any conference with any taxing authority regarding the Excise Tax or associated income taxes, the Executive
shall permit the representative of the Company to accompany the Executive, and the Executive and the Executive’s representative shall cooperate with the Company and its representative. 
 10. Successors: Binding Agreement. 
 10.1 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. 
 10.2 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. 
  

 -10- 

 11. Tax Treatment; Tax Withholding. The Company and the Executive hereby
acknowledge and agree that the Transition Bonus and any Retention Bonus payable hereunder 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 compensation or other benefits to which the Executive is entitled to hereunder such amounts as may be required to satisfy all federal, state and local withholding and employment tax
obligations. 
 12. General Provisions. 
 12.1 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.

reimburse the Executive for all legal fees and expenses which the Executive may reasonably incur as a result of any contest 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, if the Executive prevails in such contest. Following a Change of Control, 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. For the avoidance of doubt, in no event will the provisions of this Section 12.7 apply to any dispute arising out of or related to the Company’s enforcement of its rights under the Proprietary Information and Non-Competition
Agreement executed of event date herewith.

contained have been provided solely for convenience of reference and in no way define, limit or describe the scope or substance of any provision of this Agreement. 
 12.9 Severability. The provisions of this Agreement are severable, and the invalidity of any provision shall not affect the validity of any other provision. In the event that any court of
competent jurisdiction shall determine that any provision of this Agreement or the application thereof is unenforceable because of the duration or scope thereof, the parties hereto agree that said court in making such determination shall have the
power to reduce the duration and scope of such provision to the extent necessary to make it enforceable, and that the Agreement in its reduced form shall be valid and enforceable to the full extent permitted by law.

 EXHIBIT A 
 NON-COMPETITION AND PROPRIETARY INFORMATION AGREEMENT 
 THIS AGREEMENT (the “Agreement”), is made and entered into as of November 5, 2009, by and between Hologic, Inc., a Delaware corporation (the “Company”) and John W. Cumming (“Executive”). 

Recitals 
 WHEREAS, the Company and the Executive have entered into a Transition Agreement of even date herewith (the “Transition Agreement”); and 
 WHEREAS, it is a condition of the execution of the Transition Agreement that this Agreement be entered into and be incorporated by reference in the Transition Agreement as Exhibit A thereto; and

 WHEREAS, the Executive will receive substantial economic payments and benefits as a result of the Transition Agreement
and his continuing employment with the Company; and 
 WHEREAS, in his capacity as Chairman and executive officer 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 Transition 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 Transition 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. 

 (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. 
  

 2 

 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 Transition 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, for the longer of (i) three (3) years from the Effective Date or (ii) 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. 
 (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 Transition 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, 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. 
  

 3 

 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 or Chief Executive Officer 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 Transition 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 from the date on which Executive ceases such violation or from the date of entry by a court of

  

 4 

 
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 Transition 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 12.2 of the Transition 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 Transition Agreement and shall be fully valid and enforceable notwithstanding any breach or claimed breach of the Transition 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. 
  

 5 

 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 Transition 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.
