expenses for reimbursement up to $200,000. This value is pending the determination of issues relating to the sale of your home. As such, the relocation reimbursement may exceed $200,000; Hologic will work with you to agree upon the final
reimbursement amount with the understanding that any increase in the amount beyond $200,000 will be in Hologic’s sole discretion. All relocation benefits will be grossed up for taxes. A formalized Relocation Assistance Plan is forthcoming.
Additionally, you will be provided temporary housing at Hologic’s expense in advance of your relocation to the Marlborough area.

Incentive Program, you will be granted an option to purchase shares of currently authorized Company stock which will be subject to the terms and conditions set forth in Hologic’s standard stock option agreement with the value of $700,000. The

have disclosed to Hologic that you are bound by a formal non-competition, confidentiality and proprietary agreement with your previous employer, Johnson & Johnson. You have provided a copy of that document to Hologic prior to Hologic
extending this offer, and Hologic has determined to extend this offer to you based upon its own legal determination that nothing in your prior agreement with Johnson & Johnson would preclude you from working for Hologic as its Chief
Financial Officer. In the event your employment with the Hologic results in a claim (whether through arbitration or court) by Johnson & Johnson, or any parent, successor or affiliate (collectively “Johnson & Johnson”),
alleging that you have breached any covenant of your employment, non-competition, confidentiality and proprietary agreements between you and Johnson & Johnson that have been provided to Hologic for review, Hologic shall indemnify you and
hold you harmless for any expenses, judgments, penalties, fines and amounts paid in settlement actually and reasonably incurred, including all attorney’s fees. Hologic shall advance reasonable attorneys’ fees and costs incurred by you to
defend against such action. 
 Your employment with Hologic is contingent upon you signing the Employee Intellectual Property Rights and Non-Competition
Agreement, as well as the securing of satisfactory reference and background checks. As such your acceptance of this offer shall also serve as your consent to Hologic conducting all such background checks.

Confidentiality 
 You agree to follow the Company’s
policy that employees must not disclose, either directly or indirectly, any confidential information, including any of the terms of this agreement to any person including other employees of the Company. You may however discuss such terms with
members of your immediate family and any legal, tax or accounting specialists who provide you with services, and to your current employer, to the extent required by any current agreements you have with Johnson & Johnson to do so upon your
termination of employment.
