EMPLOYMENT AGREEMENT

Exhibit 10.1

EMPLOYMENT AGREEMENT

THIS EMPLOYMENT AGREEMENT (the “Agreement”) is entered into on this 8th day of May, 2013, by and between Lantheus Medical Imaging, Inc., and its predecessors, successors and assigns (the “Company”), and Jeffrey Bailey (“Executive”).

NOW, THEREFORE, in consideration of the covenants and agreements hereinafter set forth, the parties hereto agree as follows:

1.             Employment and Duties.

(a)           General.  Executive shall serve as President and Chief Executive Officer (the “CEO”) of the Company and its subsidiaries and parent entities and will report to the Board of Directors of the Company (the “Board”) and the Board of Directors of Lantheus MI Holdings, Inc., the indirect parent company of the Company (“Holdings”, and collectively with its direct and indirect subsidiaries, the “Lantheus Affiliates”).  In addition, Executive shall serve as a member of the Boards of Directors of Holdings, Lantheus MI Intermediate, Inc., the Company and the Company’s subsidiaries and affiliates without additional compensation.  In these capacities, Executive shall render such executive, managerial, administrative and other services as customarily are associated and incident to such positions, and as the Board or the Board of Directors of Holdings may, from time to time, reasonably require of him consistent with such position.  The Board shall use its reasonable efforts to cause Executive to be elected as a member of the Board in connection with and following the First Public Offering (as defined in the Shareholders Agreement) of the Company for so long as he is employed by the Company.

(b)           Exclusive Services.  For so long as Executive is employed by the Company, Executive shall devote his full time, energies and talents to serving as its, and its subsidiaries’ and parent entities’ President and CEO.  Notwithstanding the forgoing, Executive may devote reasonable time to activities other than those required under this Agreement, including activities involving professional, charitable, community, educational, religious and similar types of organizations, speaking engagements, and similar types of activities, to the extent that such activities do not, individually or in the aggregate, conflict materially with the performance of Executive’s duties under this agreement; provided, however, that Executive shall not serve on the board of any business or charitable organization, or hold any other position with any business, without the consent of the Board.  Such advance Board approval has been obtained for Executive to serve as a director of the Trenton/Mercer County Boys&Girls Club during his employment with the Company.

2.             Employment “At-Will”.  Executive’s employment commenced on January 23, 2013 (the “Start Date”).  Executive’s employment with the Company shall, at all times, be treated as “at will,” meaning that Executive’s employment may be terminated by the Company for any reason or no reason at all, unless otherwise prohibited by law.

3.             Compensation and Other Benefits.  Subject to the terms of this Agreement, the Company shall pay and provide the following compensation and other benefits to Executive as compensation for services rendered hereunder:

(a)           Base Salary.  The Company shall pay to Executive an annual base salary (the “Base Salary”) of not less than $450,000, less taxes and withholdings, payable in accordance with the regular payroll practices of the Company.  Salary increases, if any, may occur from time to time in the Company’s sole discretion.  Such salary increases will depend upon a number of factors, including but not limited to Executive’s performance, the Company’s financial performance, and the general economic environment.

(b)           Equity Participation. Concurrently with the execution of this Agreement, Executive is purchasing from Holdings, and Holdings is issuing and selling to Executive, 58,823 shares of common stock of Holdings (the “Purchased Equity”) at a per share purchase price equal to $6.80 (the “Executive Equity Purchase”) pursuant to a subscription agreement in the form attached hereto as Exhibit A (the “Subscription Agreement”).  In connection with, and as a condition to, Holdings issuing such Purchased Equity to Executive, Executive shall become party to and bound by the Amended and Restated Shareholders Agreement, dated as of February 26, 2008, by and among Holdings and the other parties thereto from time to time (as amended, supplemented or modified from time to time, the “Shareholders Agreement”) by executing a joinder agreement in the form attached as Exhibit A to the Subscription Agreement.  In addition, concurrently with the execution of this Agreement, Executive is being granted an amount of options exercisable for 1,000,000 shares of common stock of Holdings with a per share exercise price of $6.80 pursuant to an option grant award agreement in the form attached hereto as Exhibit B.

(c)           Annual Cash Bonus.  Executive shall be eligible to receive an annual, discretionary cash bonus (“Annual Cash Bonus”) less taxes and withholdings, with a target bonus opportunity of 100% of Executive’s Base Salary for the applicable calendar year (the “Target Bonus”). Annual Cash Bonuses are not guaranteed and are granted in the Company’s sole discretion, with the amount variable, based on individual and Company performance, and/or will be calculated in accordance with an applicable short-term incentive program, should the Company, in its discretion, adopt such a program in regards to Executive, in the event of which vesting and participation will be governed by and subject to the applicable plan documents.  Annual Cash Bonuses, if any, are generally paid in March of the year following the year in which the bonus was earned, by the 15th of that month, and will only be paid to the extent the same is earned, subject to Executive’s continued employment on such payment date, except as otherwise provided in Section 4 hereof.  To the extent any management or advisory fees are payable to any of Avista Capital Partners, L.P., Avista Capital Partners (Offshore), L.P., or ACP-Lantern Co-Invest LLC, such fees shall be excluded for the purpose of determining whether performance criteria based on the Company’s EBITDA were satisfied in determining the amount, if any, of Executive’s Annual Cash Bonus.

(d)           Employee Benefit Plans.  Executive shall be entitled to participate in all employee health and welfare plans and programs of the Company, in accordance with their respective terms, as may be amended from time to time, on a basis no less favorable than that made available to other senior executives of the Company.  Coverage under such plans are governed by the applicable plan documents which shall be provided to Executive.

2

(e)           Expenses.  The Company shall reimburse Executive for reasonable travel and other business-related expenses incurred by Executive in connection with the fulfillment of his duties hereunder, upon presentation of proper receipts or other proof of expenditure and subject to the applicable expense reimbursement policies and procedures of the Company as in effect from time to time.  Executive shall comply with such expense reimbursement policies and procedures as may be in effect from time to time.  In addition, for a period of 12 months following the Start Date, Executive shall be reimbursed on a monthly basis an aggregate amount of one and a half times (1.5x) Executive’s (i) properly documented commuting expenses to the Company’s headquarters in North Billerica, Massachusetts, from Executive’s current residence in the Princeton, New Jersey area, and (ii) living expenses for the renting of an apartment in the vicinity of the Company’s headquarters; provided, however, that such aggregate reimbursement shall not exceed $7,500 per month.

(f)            Vacation.  Executive shall be entitled to four (4) weeks of vacation per year.  Such vacations shall extend for such periods and be taken at such intervals as shall be appropriate and consistent with the proper performance of Executive’s duties hereunder.

4.             Termination of Employment.

(d)           Other Terminations.  Executive shall not be entitled to the post-termination benefits set forth in Section 4(a), Section 4(b) or Section 4(c) above if his employment with the Company ceases for any reason other than his termination by the Company without Cause, his resignation for Good Reason or his termination as a result of his death or Permanent Disability; it being understood that if Executive’s employment with the Company ceases or terminates for any other reason, he will not be entitled to any severance

(f)            Good Reason Definition. For purposes of this Agreement, “Good Reason” means (i) a material and adverse reduction in the nature or scope of the responsibilities of, or title held by, Executive, including, for the avoidance of doubt, any action as a result of which Executive no longer has the title of Chief Executive Officer of the Company; (ii) a material breach by the Company of this Agreement; (iii) the transfer or relocation of Executive’s principal place of employment to a location that is more than 50 miles from both of the Company’s offices in North Billerica, Massachusetts, without Executive’s prior consent; or (iv) prior to the First Public Offering (as defined in the Shareholders Agreement) of Holdings or the Company, whichever occurs earlier, the removal of Executive from the Board or any failure to elect Executive to the Board; provided, however, that, with respect to each of items (i) through (iv) in this paragraph, Executive must notify the Company in writing within thirty (30) days of the occurrence of such event, delineating with specificity the facts constituting the Good Reason and requesting that the Company remedy the situation (“Notice to Cure”), and the Company shall be given thirty (30) days from the date of receipt of the Notice Cure to remedy the alleged occurrence.

6

performing his duties as CEO, Executive will be expected to work at the Company’s headquarters in North Billerica, Massachusetts, as necessitated by business demands or as reasonably requested by the Board.

(g)           Separation Agreement and General Release.  The payments and benefits set forth in Sections 4(a), 4(b) and 4(c) above shall be expressly conditioned upon Executive’s (or his estate or legal representatives, in the case of Section 4(c)) execution and delivery to the Company of a Separation Agreement and General Release in a form that is acceptable to the Company (the “Separation Agreement”) and such Separation Agreement becoming irrevocable within sixty (60) days following Executive’s termination of employment; provided, that any payments or benefits otherwise due prior to such sixtieth (60th) day shall be paid on such sixtieth (60th) day. For the avoidance of doubt, the payments and benefits set forth in Sections 4(a), 4(b) and 4(c) above shall be forfeited if such Separation Agreement has not been executed, delivered and become irrevocable within such sixty (60) day period.  Such Separation Agreement shall contain release language substantially similar to the language set forth in Exhibit C attached hereto.

(ii)           It is expressly understood and agreed that although Executive and the Company consider the restrictions contained in this Section 5(c) to be reasonable, if a final judicial determination is made by a court of competent jurisdiction that the time or territory or any other restriction contained in this Agreement is an unenforceable restriction against Executive, the provisions of this Agreement shall not be rendered void but shall be deemed amended to apply as to such maximum time and territory and to such

11

maximum extent as such court may judicially determine or indicate to be enforceable.  Alternatively, if any court of competent jurisdiction finds that any restriction contained in this Agreement is unenforceable, and such restriction cannot be amended so as to make it enforceable, such finding shall not affect the enforceability of any of the other restrictions contained herein.

(iii)          The provisions of this Section 5(c) shall survive the termination of this Agreement and Executive’s employment for any reason.

(i)            Executive agrees that, upon and following termination of Executive’s employment with the Company for any reason, Executive will not make, publicly or privately, verbally or in writing, any false, disparaging, derogatory or otherwise inflammatory remarks about any of the Company, its parent, subsidiaries, and other related and affiliated companies, their employee benefit plans and trustees, fiduciaries, administrators, sponsors and parties-in-interest of those plans, and all of their past and present employees, managers, directors, officers, administrators, shareholders, members, agents, attorneys, insurers, re-insurers and contractors acting in any capacity whatsoever, and all of their respective predecessors, heirs, personal representatives, successors and assigns (collectively, the “Released Parties”) and/or the conduct, operations or financial condition or business practices, policies or procedures of the Released Parties to any third party, and Executive will not make or solicit any comments, statements or the like to the media or to others that may be considered derogatory or detrimental to the good name and business reputation of any of the Released Parties; provided, however, that nothing in this paragraph is intended to prohibit Executive from providing truthful information to any government entity, arbitrator, or court, or to otherwise testify truthfully under oath, as required by law.

(ii)           Upon and following termination of Executive’s employment with the Company for any reason, the Board will not make, publicly or privately, verbally or in writing, any false, disparaging, derogatory or otherwise inflammatory remarks about Executive in connection with Executive’s employment with the Company, or make or solicit any comments, statements, or the like to the media or to others that may be considered derogatory or detrimental to Executive’s good name and business reputation; provided, however, that nothing in this paragraph is intended to prohibit the Company or the members of the Board from providing truthful information to any government entity, arbitrator, or court, or to otherwise testify truthfully under oath, as required by law.

(iii)          It is expressly understood and agreed that although Executive and the Company consider the restrictions contained in this Section 5(d) to be reasonable, if a final judicial determination is made by a court of competent jurisdiction that the time or territory or any other restriction contained in this Agreement is an unenforceable restriction against Executive, the provisions of this Agreement shall not be rendered void but shall be deemed amended to apply as to such maximum time and territory and to such maximum extent as such court may judicially determine or indicate to be enforceable.  Alternatively, if any court of competent jurisdiction finds that any restriction contained in

12

this Agreement is unenforceable, and such restriction cannot be amended so as to make it enforceable, such finding shall not affect the enforceability of any of the other restrictions contained herein.

(iv)          The provisions of this Section 5(d) shall survive the termination of this Agreement and Executive’s employment for any reason.

(e)           Reasonable Restrictions; Right to Equitable Relief.  Executive acknowledges and agrees that the restrictions and covenants set forth in this Section 5 are reasonable in geographic and temporal scope and in all other respects and necessary to protect the Company and its legitimate business interests.  Executive understands and agrees that the Company will be irreparably injured by any breach of Section 5 and damages would be an inadequate remedy.  Accordingly, Executive acknowledges that, in the event of Executive’s breach or threatened breach of this Section 5, the Company shall be entitled to a restraining order in addition to preliminary, temporary and permanent injunctive relief or other equitable relief, without the requirement of posting a bond or other security; provided, however, that the granting of any such injunctive relief shall not prejudice the Company’s right to seek monetary damages for any breach of this Section 5 and any damage that they have suffered thereby, and that the Company shall be entitled to attorneys’ fees and costs incurred by the Company in enforcing the terms of this Section 5.  Any right to obtain an injunction, restraining order, or other equitable relief under this Section 5 shall not be deemed to be a waiver of any right to any other remedy that the Company may have at law or in equity.  Notwithstanding anything else to the contrary herein, in the event of any violation by Executive of this Section 5, the Company shall immediately have no obligation thereafter to make any payments to or confer any benefits on Executive that are set forth in this Agreement.

6.             Indemnification. Executive shall be indemnified pursuant to and in accordance with the terms and conditions set forth in the Certificates of Incorporation of the Company and of Holdings, and in the Company’s or Holdings’ Directors and Officers Liability Insurance Policy then in effect, which policy shall provide Executive coverage, during and after his employment with the Company, on the same basis as the Company’s other directors and officers.

7.             Successors and Assigns.  This Agreement shall be binding upon, and inure to the benefit of, the Company and its successors and assigns and may be assigned by the Company without Executive’s consent in connection with any person acquiring, whether by merger, consolidation, purchase of stock, assets or otherwise, all or substantially all of the Company’s assets and business, and the successor shall be substituted for the Company under this Agreement.

8.             Withholding.  Any payments made or benefits provided to Executive under this Agreement shall be reduced by any applicable withholding taxes or other amounts required to be withheld by law or contract.

9.             Cooperation. Executive agrees to cooperate fully and in good faith with the Company and its legal counsel, both during and after his employment with the Company, in connection with any defense, prosecution or investigation of any and all actual,

13

threatened, potential or pending court or administrative proceedings or other legal matters in which Executive may be involved as a party and/or in which the Company determines, in its sole discretion, that Executive is a relevant witness or has relevant knowledge or information.  In connection with such matters, Executive agrees to notify, communicate and be represented by counsel of the Company’s choosing, to fully cooperate and work with such counsel with respect to, and in preparation for, any depositions, interviews, responses, appearances, or other legal matters, and to testify honestly with respect to all matters.  Executive is also entitled to appoint, at his request, his own legal counsel in addition to the Company’s counsel in connection with any legal matters covered by this Agreement; provided, that, unless such legal matters relate to claims for which Executive is seeking indemnification, in which case the relevant insurance policy or other document, agreement or instrument governing Executive’s to right to seek indemnification shall apply, the Company will pay the reasonable and documented expenses of Executive’s own legal counsel if it is determined that Executive’s interests are adverse to or in conflict with those of the Company and/or that providing counsel to Executive would be a conflict of interest.

10.          Acknowledgement by Executive. Executive represents and warrants that (i) he is not, and will not become, a party to any agreement, contract, arrangement, understanding, covenant or restriction contained in any agreement that in any way restricts or prohibits him from undertaking or performing his duties in accordance with this Agreement or that restricts his ability to be employed by the Company in accordance with this Agreement; (ii) his employment by the Company will not violate the terms of any policy of any prior employer of Executive regarding competition or solicitation; and (iii) his position with the Company will not require him to improperly use any trade secrets or confidential information of any prior employer, or any other person or entity for whom he has performed services, and that he has not taken with him or disclosed to the Company any confidential information from any prior employment or any other entity for whom he has performed services.

11.          Section 409A.

(a)           The intent of the parties is that the payments and benefits under this Agreement comply with or be exempt from Section 409A and, accordingly, to the maximum extent permitted, this Agreement shall be interpreted to be in compliance therewith.  To the extent that any provision hereof is modified in order to comply with or be exempt from Section 409A, such modification shall be made in good faith and shall, to the maximum extent reasonably possible, maintain the original intent and economic benefit to Executive and the Company of the applicable provision without violating the provisions of Section 409A.

(b)           If any payment, compensation or other benefit provided to Executive under this Agreement in connection with Executive’s “separation from service” (within the meaning of Section 409A) is determined, in whole or in part, to constitute “nonqualified deferred compensation” (within the meaning of Section 409A) and Executive is a specified employee (as defined in Section 409A(a)(2)(B)(i)) at the time of separation from service, no part of such payments shall be paid before the day that is six months plus one day after the date of separation or, if earlier, ten business days following Executive’s

14

death (the “New Payment Date”).  The aggregate of any payments and benefits that otherwise would have been paid and/or provided to Executive during the period between the date of separation of service and the New Payment Date shall be paid to Executive in a lump sum on such New Payment Date.  Thereafter, any payments and/or benefits that remain outstanding as of or following the New Payment Date shall be paid without delay over the time period originally scheduled, in accordance with the terms of this Agreement.

(c)           A termination of employment shall not be deemed to have occurred for purposes of any provision of this Agreement providing for the payment of any amounts or benefits subject to Section 409A upon or following a termination of employment unless such termination is also a “separation from service” (within the meaning of Section 409A), and for purposes of any such provision of this Agreement, references to a “resignation,” “termination,” “terminate,” “termination of employment” or like terms shall mean separation from service (within the meaning of Section 409A).

(d)           All expenses or other reimbursements as provided herein shall be payable in accordance with the Company’s policies in effect from time to time, but in any event shall be made on or prior to the last day of the taxable year following the taxable year in which such expenses were incurred by Executive.  With regard to any provision herein that provides for reimbursement of costs and expenses or in-kind benefits, except as permitted by Section 409A: (i) the right to reimbursement or in-kind benefits shall not be subject to liquidation or exchange for another benefit; and (ii) the amount of expenses eligible for reimbursements or in-kind benefits provided during any taxable year shall not affect the expenses eligible for reimbursement or in-kind benefits to be provided in any other taxable year.

(e)           For purposes of Section 409A, Executive’s right to receive any installment payments pursuant to this Agreement shall be treated as a right to receive a series of separate and distinct payments.  Whenever a payment under this Agreement specifies a payment period with reference to a number of days (e.g., payment shall be made within 30 days following the date of termination), the actual date of payment within the specified period shall be within the sole discretion of the Company.

12.          Amendment; Waiver.  This Agreement may not be modified, amended or waived in any manner, except by an instrument in writing signed by both parties hereto.  The waiver by either party of compliance with any provision of this Agreement by the other party shall not operate or be construed as a waiver of any other provision of this Agreement, or of any subsequent breach by such party of a provision of this Agreement.

13.          Governing Law and Forum Selection.

(a)           All disputes, claims or controversies arising out of or relating to this Agreement, or the negotiation, validity or performance of this Agreement, or the transactions contemplated hereby, shall be governed by and construed in accordance with the internal laws of the State of Delaware applicable to agreements made and to be performed entirely within such State, without regard to the conflict of laws principles of such State.

15

(b)           In connection with any litigation arising out of or relating to this Agreement, the negotiation, execution, delivery, performance or validity of this Agreement, or the transactions contemplated hereby, each of the parties hereto irrevocably and unconditionally (i) consents to submit to the sole and exclusive jurisdiction of (x) any state court of the State of Delaware having subject matter jurisdiction over the matter and sitting in the city of Wilmington, Delaware or (y) any court of the United States located in the State of Delaware, if under applicable law exclusive jurisdiction over the matter is vested in the federal courts; (ii) agrees not to commence any litigation relating thereto except in the courts identified in accordance with clause (i) hereof and waives any objection to the laying of venue of any such litigation in any such court; and (iii) agrees not to plead or claim in any such court that such litigation brought therein has been brought in an inconvenient forum.  Each of the parties hereto agrees that service of process may be made on such party by prepaid certified mail with a proof of mailing receipt validated by the United States Postal Service constituting evidence of valid service.  Service made pursuant to the preceding sentence shall have the same legal force and effect as if served upon such party personally within the State of Delaware.

14.          Entire Agreement.  This Agreement between the Company and Executive and the other agreements and arrangements referred to herein, each as amended from time to time, contains the entire agreement and understanding of the parties hereto with respect to the matters covered herein and supersedes all prior or contemporaneous negotiations, commitments, agreements and writings with respect to the subject matter hereof, all such other negotiations, commitments, agreements and writings shall have no further force or effect, and the parties to any such other negotiation, commitment, agreement or writing shall have no further rights or obligations there-under.  This Agreement may not be changed or terminated orally but only by an agreement in writing signed by the parties thereto.
