Timothy Healey

c/o Lantheus Medical Imaging, Inc.

331 Treble Cove Road

Dear Tim:

This letter agreement (this “Agreement”) confirms the terms of your separation from Lantheus Medical Imaging, Inc. (the “Company”), effective as of July 25, 2018 (the “Separation Date”).

Resignations. On the Separation Date, you will be deemed to have resigned from your position as Senior Vice President, Commercial and from any and all (i) officer positions you hold with the Company or any of its Affiliates (as defined below); (ii) memberships you hold on any boards of directors, boards of managers or other governing boards or bodies of the Company or any of its Affiliates; and (iii) memberships you hold on any of the committees of any of those boards or bodies. For purposes of this Agreement, “Affiliates” means all persons and entities directly or indirectly controlling, controlled by or under common control with the Company, whether control by management authority, equity interest or otherwise.

Final Compensation. You will receive, on or as soon as reasonably practicable following the Separation Date, in the form of one or more payroll checks, (i) your base salary for the final, unpaid payroll period(s) of your employment through the Separation Date; (ii) compensation at the rate of your base salary for any vacation time accrued but not used as of the Separation Date; (iii) any contributions that you have made under any employee stock purchase plan of Lantheus Holdings, Inc. (“Parent”) or any of its Affiliates that are refundable to you under its respective terms and conditions; and (iv) reimbursement for business expenses incurred by you but not yet paid to you as of the Separation Date; provided that you submit all expenses and supporting documentation required within thirty (30) days of the Separation Date and that those expenses are reimbursable under Company policies in effect as of the Separation Date.

Employee Benefits. Except for any right you may have to continue your participation and that of your eligible dependents in the Company’s group health plans under the Consolidated Omnibus Budget Reconciliation Act of 1985 (“COBRA”) or similar state law, your participation in all employee benefit plans and programs of the Company and its Affiliates will end as of the last day of the month in which the Separation Date occurs. You will receive information about your COBRA continuation rights under separate cover.

Equity Awards. You hold certain equity awards granted to you by Lantheus Holdings, Inc. (“Parent”), an Affiliate of the Company, under its 2008 Equity Incentive Plan, 2013 Equity Incentive Plan and/or 2015 Equity Incentive Plan, each as amended, and the equity incentive agreements evidencing those grants entered into between you and Parent under those plans (collectively, the “Equity Agreements” and those equity awards, collectively, the “Equity Awards”). You acknowledge and agree that all Equity Awards that are unvested as of the Separation Date are being forfeited for no consideration due to you in accordance with the Equity Agreements, and all of your then-vested Equity Awards will continue to be subject to the terms and conditions of the applicable Equity Agreements, including the post-termination of employment exercise provisions thereof.


5.	Severance Payments. Subject to your execution of this Agreement within fifty (50) days following the Separation Date and your not revoking this Agreement within the seven (7)-day period immediately thereafter, and subject to your meeting in full your obligations under this Agreement and the Continuing Obligations (as defined in Section 8(a) below), the Company will provide you with the following:

(a)

an amount equal to the sum of (x) $228,589.04, representing a pro rata portion of an amount equal to forty-five percent (45%) of your annual base salary on the Separation Date, based upon the percentage of the fiscal year elapsed through Separation Date, plus (y) $407,000.00, representing your annual base salary, which amount (i.e., the sum of clauses (x) and (y)) will be paid in substantially equal installments over a period of twelve (12)

months following the Separation Date (the “Severance Period”) in accordance with the Company’s regular payroll practices, with the first payment commencing on the Company’s first payroll date after the sixtieth (60^th) day following the Separation Date, and with the first payment including any of those amounts that would otherwise have been paid prior thereto; and

(b)

provided that you timely and properly elect to purchase continued healthcare coverage under COBRA, Company-subsidized COBRA benefits (in an amount representing the Company’s contribution level for active employees at the time of payment) for the period ending on the earliest of (i) the expiration of the Severance Period, (ii) the date on which you become covered under another employer’s health plan and (iii) the expiration of the maximum COBRA continuation coverage period for which you are eligible under federal law (for the avoidance of doubt, during this subsidized period, you will be responsible for paying a COBRA premium equal to the active employee contribution rate directly to the Company’s COBRA administrator, and you will be responsible for paying the entirety of the COBRA premium directly to the Company’s COBRA administrator after this period).

Acknowledgement of Full Payment. You acknowledge and agree that the payments and other benefits provided under this Agreement are in complete satisfaction of any and all compensation and benefits due to you from the Company or any of its Affiliates, whether for services provided to the Company or otherwise, through the Separation Date. You further acknowledge that, except as expressly provided under this Agreement, no further compensation or benefits are owed or will be provided to you by the Company or any of its Affiliates.

Taxes and Withholding. All payments made by the Company under this Agreement will be reduced by any tax or other amounts required to be withheld by the Company under applicable law. This Agreement and the payments and benefits provided under this Agreement are intended to be exempt from the requirements of Section 409A of the Internal Revenue Code of 1986, as amended (“Section 409A”), and this Agreement will be construed consistently with that intent. Without limiting the foregoing, the severance payments set forth in Section 5 of this Agreement are intended to be exempt from Section 409A as “separation pay” within the meaning of Section 1.409A-1(b)(9)(iii) of the Treasury Regulations. Notwithstanding anything to the contrary, in no event will the Company have any liability relating to the failure or alleged failure of any payment or benefit under this Agreement to be exempt from the requirements of Section 409A.


8.	Continuing Obligations.

(a)

You acknowledge and recognize the highly competitive nature of the businesses of the Company and its Affiliates and, accordingly, in consideration of the severance pay and benefits set forth in Section 5 and other valuable consideration, you acknowledge and agree that you will continue to be bound by your obligations relating to confidentiality, non-competition, non-solicitation, no-hire, invention assignment, non-disparagement and/or any other restrictive covenant set forth in any agreement by and between you and the Company or any of its Affiliates, including, without limitation, those set forth in Sections 10-13 of the employment agreement, dated November 16, 2015, between you and the Company (the “Employment Agreement”) (all such obligations, collectively, the “Continuing Obligations”). Each of the Continuing Obligations is an individual right, separately enforceable by the Company and/or its applicable Affiliate(s), notwithstanding any conflict or other inconsistency among any provisions (or any parts of any provisions) of any of the Continuing Obligations, and no such conflict or other inconsistency will have the effect of superseding, restricting or otherwise limiting any of the Continuing Obligations. The obligation of the Company to make payments to you under Section 5, and your right to retain those payments, are expressly conditioned upon your continued full performance of your obligations under this Agreement and of the Continuing Obligations.


(b)	You agree not to disclose to any individual or entity any of the terms of, or amounts paid under, this Agreement; provided, however, that you will not be prohibited from making disclosures to your spouse or domestic partner, attorney or tax advisor.

(c)

You hereby assign to the Company all right, title and interest that you have in any discovery, invention or innovation conceived or reduced to practice by you in the performance of your employment with the Company (including all intellectual property rights related to any discovery, invention or innovation), which you acknowledge and agree is solely and exclusively owned by the Company. You will cooperate and assist the Company (at the Company’s expense) in obtaining patent protection for any such discovery, invention or innovation, including executing all documents required for such purpose, and you hereby irrevocably appoint the Company as your lawful attorney-in-fact for such purpose. This Agreement will also be deemed a transfer

to the Company of, and you hereby assign to the Company, the copyright of any copyrightable subject matter created by you in the performance of your employment with the Company.

(d)

For the avoidance of doubt, (i) nothing contained in the Employment Agreement or this Agreement, or any of the Continuing Obligations, limits, restricts or in any other way affects your communicating with any governmental agency or entity, or communicating with any official or staff person of any governmental agency or entity, concerning matters relevant to that governmental agency or entity; and (ii) you will not be held criminally or civilly liable under any federal or state trade secret law for disclosing a trade secret (y) in confidence to a federal, state or local government official, either directly or indirectly, or to an attorney, solely for the purpose of reporting or investigating a suspected violation of law, or (z) in a complaint or other document filed under seal in a lawsuit or other proceeding; provided, however, that notwithstanding this immunity from liability, you may be held liable if you unlawfully access trade secrets by unauthorized means or disclose (except as permitted above) or use any trade secrets.

Return of Company Documents and Other Property. In signing this Agreement, you represent, warrant and covenant that you have returned to the Company any and all documents, materials and information (whether in hardcopy, on electronic media or otherwise) related to the business of the Company and its Affiliates (whether present or otherwise), and all keys, access cards, credit cards, computer hardware and software, telephones and telephone-related equipment and all other property of the Company or any of its Affiliates in your possession or control. Further, you represent, warrant and covenant that you have not retained any copy or derivation of any documents, materials or information (whether in hardcopy, on electronic media or otherwise) of the Company or any of its Affiliates. Further, you represent, warrant and covenant that you have disclosed to the Company all passwords necessary or desirable to obtain access to, or that would assist in obtaining access to, all information which you have password-protected on any computer equipment, network or system of the Company or any of its Affiliates.

(a)

This Agreement constitutes the entire agreement between you and the Company or any of its Affiliates, and supersedes all prior and contemporaneous communications, agreements and understandings, whether written or oral, with respect to your employment, its termination and all related matters, excluding only the Continuing Obligations, which will remain in full force and effect in accordance with their terms.

(b)

This Agreement is a Massachusetts contract, and this Agreement (and all claims, controversies and causes of action arising under or otherwise relating to this Agreement) will be governed and construed in accordance with the laws of the Commonwealth of Massachusetts, without regard to any conflict of laws principles that would result in the application of the laws of another jurisdiction.
