Item 1.01 Entry into a Material Definitive Agreement

Merger Agreement

On October 1, 2019, Lantheus Holdings, Inc. (“Lantheus Holdings”) and Plato Merger Sub, Inc., a wholly owned subsidiary of Lantheus Holdings (“Merger Sub”), entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Progenics Pharmaceuticals, Inc. (“Progenics”). The Merger Agreement provides, among other things, that on the terms and subject to the conditions set forth therein, Merger Sub will merge with and into Progenics, with Progenics surviving as a wholly owned subsidiary of Lantheus Holdings (the “Merger”).

In the Merger, each share of Progenics common stock issued and outstanding immediately prior to the effective time of the Merger (other than certain excluded shares as described in the Merger Agreement) will automatically be converted into the right to receive 0.2502 of a share of Lantheus Holdings common stock (the “Exchange Ratio”). In addition, upon the closing of the Merger, all Progenics stock options, whether vested or unvested, will be assumed by Lantheus Holdings and converted into options to purchase Lantheus Holdings shares of common stock. The number of shares subject to the assumed stock options and the exercise price of such stock options will be adjusted upon the closing of the Merger based on the Exchange Ratio. Such options will otherwise have the same vesting and other terms as applied to the Progenics stock options prior to the closing.

At the effective time of the Merger, the board of directors of Lantheus Holdings (the “Lantheus Board”) will appoint one member who is (i) a member of the board of directors of Progenics as of the date of the Merger Agreement, (ii) mutually agreed to by Progenics and Lantheus Holdings, acting in good faith, and (iii) reasonably approved by the Nominating and Corporate Governance Committee of the Lantheus Board.

Completion of the Merger is subject to customary closing conditions, including (among others) (1) the adoption of the Merger Agreement by a majority of the holders of the outstanding shares of Progenics common stock, (2) approval of the issuance of Lantheus Holdings common stock issued in the Merger by a majority of the votes cast by Lantheus Holdings stockholders on the matter, (3) approval for listing on the Nasdaq Global Market of Lantheus Holdings common stock, (4) the expiration or early termination of the applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, (5) accuracy of the other party’s representations and warranties, subject to certain materiality standards set forth in the Merger Agreement, (6) compliance in all material respects with the other party’s obligations under the Merger Agreement and (7) the absence of a material adverse effect on Progenics.

Either Progenics or Lantheus Holdings may terminate the Merger Agreement in certain circumstances, including if (1) the Merger is not completed by July 1, 2020, (2) Progenics’ stockholders fail to adopt the Merger Agreement, (3) Lantheus Holdings’ stockholders fail to approve the share issuance in connection with the Merger, (4) a governmental authority of competent jurisdiction has issued a final non-appealable governmental order prohibiting the Merger, (5) the other party breaches its representations, warranties or covenants in the Merger Agreement in a way that would entitle the party seeking to terminate the Merger Agreement not to consummate the Merger, subject to the right of the breaching party to cure the breach, (6) the other party’s board of directors has changed its recommendation in favor of the Merger or (7) the other party willfully and materially breaches certain covenants contained in the Merger Agreement. In the event of a termination of the Merger Agreement under certain specified circumstances, including a termination by Lantheus Holdings following a change in recommendation by Progenics’ board of directors or a willful and material breach of the no-solicitation provision applicable to Progenics, Progenics may be required to pay Lantheus Holdings a termination fee equal to $18,340,000 (the “Company Termination Fee”). In the event of a termination of the Merger Agreement under certain

specified circumstances, including a termination by Progenics following a change in recommendation by Lantheus Holdings’ board of directors or a willful and material breach of the no-solicitation provision applicable to Lantheus Holdings, Lantheus Holdings may be required to pay Progenics a termination fee equal to $18,340,000. In the event of a termination of the Merger Agreement as a result of Progenics stockholders failing to adopt the Merger Agreement, Progenics may be required to reimburse the reasonable and documented out-of-pocket expenses incurred by Parent and its subsidiaries in connection with the Merger Agreement not to exceed $5,240,000.

If Progenics willfully and materially breaches the Merger Agreement and the Merger Agreement is thereafter terminated, Progenics may be required to pay damages to Lantheus Holdings equal to $18,340,000, net of any previously paid expense reimbursement paid to Lantheus Holdings by Progenics, unless Progenics has previously paid the Company Termination Fee.

The foregoing description of the Merger and the Merger Agreement is not complete and is qualified in its entirety by the full text of the Merger Agreement, a copy of which is attached hereto as Exhibit 2.1 and the terms of which are incorporated herein by reference.

Important Statement Regarding the Merger Agreement

The Merger Agreement has been included to provide investors and security holders with information regarding its terms. It is not intended to provide any other factual information about Lantheus Holdings, Merger Sub, Progenics or their respective subsidiaries and affiliates. The Merger Agreement contains representations and warranties by Lantheus Holdings and Merger Sub, on the one hand, and by Progenics, on the other hand, made solely for the benefit of the other. The assertions embodied in those representations and warranties are qualified by information in confidential disclosure schedules delivered by each party in connection with the signing of the Merger Agreement. Moreover, certain representations and warranties in the Merger Agreement were made as of a specified date, may be subject to a contractual standard of materiality different from what might be viewed as material to stockholders or may have been used for the purpose of allocating risk between Lantheus Holdings and Merger Sub, on the one hand, and Progenics, on the other hand. Accordingly, the representations and warranties in the Merger Agreement are not necessarily characterizations of the actual state of facts about Lantheus Holdings or Progenics at the time they were made or otherwise. In addition, information concerning the subject matter of the representations and warranties may change after the date of the Merger Agreement, which subsequent information may or may not be fully reflected in Lantheus Holdings’ or Progenics’ public disclosures. The Merger Agreement should not be read alone but should instead be read in conjunction with the other information regarding the Merger Agreement, the Merger, Lantheus Holdings, Progenics, their respective affiliates and their respective businesses, that will be contained in, or incorporated by reference into, the Registration Statement on Form S-4 that will include a joint proxy statement of Progenics and Lantheus Holdings and a prospectus of Lantheus Holdings, as well as in the Forms 10-K, Forms 10-Q and other filings that each of Lantheus Holdings and Progenics make with the Securities and Exchange Commission (“SEC”).

EXCHANGE OF SHARES

Section 3.1 Surrender and Payment.

(a) Prior to the Effective Time, Parent shall appoint an exchange agent reasonably acceptable to the Company (the “Exchange Agent”) for the purpose of exchanging shares of Company Common Stock for the Merger Consideration payable in respect thereof. As soon as reasonably practicable after the Effective Time, Parent will send, or will cause the Exchange Agent to send, to each holder of record of one or more Certificates as of the Effective Time, whose shares of Company Common Stock were converted into the right to receive the Merger Consideration pursuant to Section 2.6 (Effect on Capital Stock), a letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon proper delivery of the Certificates to the Exchange Agent) in such form as Parent may specify subject to the Company’s reasonable approval prior to the Effective Time, including instructions for use in effecting the surrender of Certificates (or effective affidavits of loss in lieu thereof) to the Exchange Agent in exchange for the Merger Consideration. At the Effective Time, Parent shall cause to be deposited with the Exchange Agent, for the benefit of the holders of shares of Company Common Stock, shares of Parent Common Stock (which shall be in non-certificated book-entry form) to be issued pursuant to Section 2.6 (Effect on Capital Stock) and an amount of cash in U.S. dollars sufficient to be paid pursuant to Section 3.5 (No Fractional Shares), payable to holders of the Book-Entry Shares or payable to the holders of Certificates upon due surrender of the Certificates (or effective affidavits of loss in lieu thereof), in each case, pursuant to the provisions of Article II and this Article III. Following the Effective Time, Parent agrees to make available to the Exchange Agent, from time to time as needed, cash in U.S. dollars sufficient to pay any dividends pursuant to Section 3.1(f) (Dividends). All cash and book-entry shares representing Parent Common Stock deposited with the Exchange Agent shall be referred to in this Agreement as the “Exchange Fund”. The Exchange Agent shall deliver the Merger Consideration (and any cash to be paid in lieu of any fractional share of Parent Common Stock in accordance with Section 3.5 (No Fractional Shares) or cash to be paid for dividends in accordance with Section 3.1(f)) out of the Exchange Fund. The Exchange Fund shall not be used for any other purpose. The Exchange Agent shall invest any cash included in the Exchange Fund as directed by Parent. Any interest and other income resulting from such investments shall be the property of, and paid to, Parent.

(b) Each holder of one or more Certificate(s) representing shares of Company Common Stock that have been converted into the right to receive the Merger Consideration, upon surrender to the Exchange Agent of such Certificate(s) (or effective affidavit of loss in lieu thereof), together with a properly completed letter of transmittal, duly executed and completed in accordance with the instructions thereto, and such other documents as may reasonably be required by the Exchange Agent, will be entitled to receive in exchange therefor (i) the number of whole shares of Parent Common Stock (which shall be in non-certificated book-entry form unless a physical certificate is requested) representing, in the aggregate, the whole number of shares of Parent Common Stock, if any, that such holder has the right to receive pursuant to Section 2.6 (Effect on Capital Stock), (ii) if applicable, any cash to be paid in lieu of any fractional share of Parent Common Stock in accordance with Section 3.5 (No Fractional Shares) and (iii) if applicable, any dividends in accordance with Section 3.1(f) (Dividends), in each case, without interest (less any required Tax withholding). Until so surrendered, each such Certificate shall, after the Effective Time, represent for all purposes only the right to receive such (A) Merger Consideration, (B) cash in lieu of any fractional shares and (C) unpaid dividends. No holder of Book-Entry Shares shall be required to deliver a Certificate or completed letter of transmittal to the Exchange Agent to receive (1) the number of whole shares of Parent Common Stock (which shall be in non-certificated book-entry form unless a physical certificate is requested) representing, in the aggregate, the whole number of shares of Parent Common Stock, if any, that such holder has the right to receive pursuant to Section 2.6 (Effect on Capital Stock), (2) if applicable, any cash to be paid in lieu of any fractional share of Parent Common Stock in accordance

16

with Section 3.5 (No Fractional Shares) and (3) if applicable, any dividends in accordance with Section 3.1(f) (Dividends), in each case, without interest (less any required Tax withholding). No interest shall be paid or accrued on any Merger Consideration, cash in lieu of fractional shares or unpaid dividends payable to holders of Certificates or Book-Entry Shares.

(c) With respect to Certificate(s), in the event of a transfer of ownership of any Certificate that is not registered in the transfer books of the Company as of the Effective Time, (i) any Merger Consideration, (ii) if applicable, any cash to be paid in lieu of any fractional share of Parent Common Stock in accordance with Section 3.5 (No Fractional Shares) and (iii) if applicable, any dividends in accordance with Section 3.1(f) (Dividends), in each case, may be issued or paid to such a transferee if the Certificate is presented to the Exchange Agent, properly endorsed or otherwise in proper form for transfer, accompanied by all documents required to evidence and effect such transfer and to evidence that any applicable stock transfer Taxes have been paid or are not applicable, in each case, in form and substance, reasonably satisfactory to the Exchange Agent. With respect to Book-Entry Shares, issuance or payment of (1) any Merger Consideration, (2) if applicable, any cash to be paid in lieu of any fractional share of Parent Common Stock in accordance with Section 3.5 (No Fractional Shares) and (3) if applicable, any dividends in accordance with Section 3.1(f) (Dividends), in each case, shall only be made to the Person in whose name such Book-Entry Shares are registered in the stock transfer books of the Company as of the Effective Time.

(d) From and after the Effective Time, there shall be no further registration of transfers of shares of Company Common Stock. From and after the Effective Time, the holders of Certificates representing shares of Company Common Stock outstanding immediately prior to the Effective Time shall cease to have any rights with respect to such shares of Company Common Stock except as otherwise provided in this Agreement or by applicable Law. If, after the Effective Time, Certificates are presented to the Exchange Agent or Parent, they shall be cancelled and exchanged for the consideration provided for, and in accordance with the procedures set forth, in Article II and this Article III.

(e) Any portion of the Exchange Fund that remains unclaimed by the holders of shares of Company Common Stock one year after the Effective Time shall be returned to Parent, and any such holder who has not exchanged his or her shares of Company Common Stock for the Merger Consideration in accordance with this Section 3.1 prior to that time shall thereafter look only to Parent for delivery of the Merger Consideration in respect of such holder’s shares of Company Common Stock. Notwithstanding the foregoing, neither Parent, Merger Sub, nor the Company shall be liable to any holder of shares of Company Common Stock for any Merger Consideration, cash in lieu of fractional shares or any unpaid dividends delivered to any Governmental Entity pursuant to applicable abandoned property Laws. Any Merger Consideration, cash in lieu of fractional shares or any unpaid dividends remaining unclaimed by holders of shares of Company Common Stock immediately prior to such time as such amounts would otherwise escheat to or become property of any Governmental Entity shall, to the extent permitted by applicable Law, become the property of Parent free and clear of any claims or interest of any Person previously entitled thereto.

(f) No dividends with respect to shares of Parent Common Stock issued in the Merger shall be paid to the holder of any Certificates or Book-Entry Shares until such Certificates or Book-Entry Shares are surrendered or transferred, as applicable, as provided in this Section 3.1. Following such surrender, subject to the effect of escheat or abandoned property (in accordance with Section 3.1(e)), Tax or other applicable Law, shall be paid, without interest, to the record holder of the shares of Parent Common Stock issued in exchange therefor (i) at the time of such surrender, all dividends payable in respect of such shares of Parent Common Stock with a record date after the Effective Time and a payment date on or prior to the date of such surrender and not previously paid and (ii) at the appropriate payment date, the dividends payable with respect to such shares of Parent Common Stock with a record date after the Effective Time but with a payment date subsequent to such surrender. For purposes of dividends in respect of shares of Parent Common Stock, all shares of Parent Common Stock to be issued pursuant to the Merger shall be entitled to dividends pursuant to the immediately preceding sentence as if issued and outstanding as of the Effective Time.

17

Section 3.2 Lost, Stolen or Destroyed Certificates. If any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such Certificate to be lost, stolen or destroyed and, if required by Parent, the posting by such Person of a bond, in such reasonable amount as Parent may direct, as indemnity against any claim that may be made against it with respect to such Certificate, the Exchange Agent will issue in exchange for such lost, stolen or destroyed Certificate the Merger Consideration, any cash to be paid in lieu of any fractional share of Parent Common Stock in accordance with Section 3.5 (No Fractional Shares) and, if applicable, any dividends in accordance with Section 3.1(f) (Dividends) to be paid in respect of the shares of Company Common Stock represented by such Certificate as contemplated by this Article III.

Section 3.3 Withholding Rights. Each of Parent and the Surviving Corporation shall be entitled to deduct and withhold, or cause the Exchange Agent to deduct and withhold, from the consideration otherwise payable to any Person pursuant to this Agreement such amounts as it is required to deduct and withhold with respect to the making of such payment under the Code or any provision of state, local or foreign Tax Law. To the extent that amounts are so deducted or withheld and paid over to the applicable Governmental Entity or Taxing Authority, such deducted or withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of shares of Company Common Stock in respect of which such deduction and withholding was made.

Section 3.4 Further Assurances. After the Effective Time, the officers and directors of the Surviving Corporation will be authorized to execute and deliver, in the name and on behalf of the Company and Merger Sub, any deeds, bills of sale, assignments or assurances and to take and do, in the name and on behalf of the Company or Merger Sub, as applicable, any other actions and things to vest, perfect or confirm of record or otherwise in the Surviving Corporation any and all right, title and interest in, to and under any of the rights, properties or assets acquired or to be acquired by the Surviving Corporation as a result of, or in connection with, the Merger

Section 3.5 No Fractional Shares. No certificates or scrips representing fractional shares of Parent Common Stock shall be issued in exchange for shares of Company Common Stock, no dividends of Parent shall relate to such fractional share interests and such fractional share interests shall not entitle the owner thereof to vote or to any rights of a stockholder of Parent. In lieu of such fractional share interests, Parent or the Exchange Agent shall pay to each holder of Company Common Stock an amount in cash equal to the product obtained by multiplying (a) the fraction of a share (after taking into account all shares of Company Common Stock held by such holder at the Effective Time and rounded to the nearest one thousandth when expressed in decimal form) of Parent Common Stock to which such holder would otherwise be entitled to receive pursuant to Section 2.6 (Effect on Capital Stock) by (b) the average of the volume weighted average price per share of Parent Common Stock on the Nasdaq Global Market (as reported in The Wall Street Journal or, if not reported therein, in another authoritative source mutually selected by Parent and the Company) on each of the 20 consecutive trading days ending with the second complete trading day prior to the Closing Date.

Section 4.7 SEC Reports; Company Financial Statements.

(a) The Company has timely filed or furnished all reports, schedules, forms, statements and other documents required to be filed or furnished by it with or to the SEC since January 1, 2017 (together with all exhibits, financial statements and schedules thereto, all information incorporated therein by reference and all documents filed with the SEC during such period by the Company on a voluntary basis, the “Company SEC Documents”). As of its filing (or furnishing) date or, if amended prior to the date of this Agreement, as of the date of the last such amendment, each Company SEC Document complied in all material respects with the applicable requirements of the Exchange Act and the Securities Act, as the case may be. As of its filing date or, if amended prior to the date of this Agreement, as of the date of the last such amendment, each Company SEC Document filed pursuant to the Exchange Act did not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements made therein, in light of the circumstances under which they were made, not misleading. Each Company SEC Document that is a registration statement, as amended or supplemented, if applicable, filed pursuant to the Securities Act, as of the date such registration statement or amendment became effective prior to the date of this Agreement, did not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements made therein, in light of the circumstances under which they were made, not misleading. None of the Company Subsidiaries are required to make any filings with the SEC.

(b) The Company Financial Statements, which have been prepared, in all material respects, from the books and records of the Company and the Company Subsidiaries, comply as to form in all material respects with the applicable accounting requirements and the published rules and regulations of the SEC with respect thereto and have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) applied on a consistent basis throughout the periods presented, except as otherwise noted therein. The Company Financial Statements (including the related notes) present fairly in all material respects the consolidated financial position of the Company and the Company Subsidiaries as at the respective dates thereof and their consolidated results of operations and cash flows for the periods then ended (subject to normal and recurring year-end audit adjustments in the case of any unaudited interim financial statements).

22

(c) As of the date hereof, there are no material outstanding or unresolved written comments from the SEC with respect to the Company SEC Documents. As of the date hereof, none of the Company SEC Documents are, to the knowledge of the Company, the subject of ongoing SEC review.

(d) The audit committee of the Board of Directors of the Company has established “whistleblower” procedures that meet the requirements of Exchange Act Rule 10A-3, and has delivered or made available to Parent true, complete and correct copies of such procedures in effect as of the date of this Agreement. Since January 1, 2017, neither the Company nor any Company Subsidiary has received any “complaints” (within the meaning of Exchange Act Rule 10A-3) in respect of any accounting, internal accounting controls or auditing matters.

(e) To the extent required by the Exchange Act, the Company and the Company Subsidiaries have established and maintain disclosure controls and procedures (as defined in Rule 13a-15 under the Exchange Act) designed to ensure that material information relating to the Company, including the Company Subsidiaries, is made known to the Company’s principal executive officer and its principal financial officer by others within those entities, including during the periods in which the periodic reports required under the Exchange Act are being prepared. Each of the principal executive officer of the Company and the principal financial officer of the Company (or each former principal executive officer of the Company and each former principal financial officer of the Company, as applicable) has made all certifications required by Rule 13a-14 or 15d-14 under the Exchange Act and Sections 302 and 906 of the Sarbanes-Oxley Act with respect to the Company SEC Documents, and the statements contained in such certifications are true and accurate in all material respects as of the date on which they were made. For purposes of this Section 4.7, “principal executive officer” and “principal financial officer” shall have the meanings given to such terms in the Sarbanes-Oxley Act. Since January 1, 2017, the Company has complied in all material respects with the provisions of the Sarbanes-Oxley Act.

(f) The Company maintains a system of “internal control over financial reporting” (as defined in Rule 13a-15(f) of the Exchange Act) designed to provide reasonable assurance regarding the reliability of the Company’s financial reporting and the preparation of the Company’s financial statements for external purposes in accordance with GAAP. The Company’s principal executive officer and principal financial officer have disclosed, based on their most recent evaluation of such internal controls prior to the date of this Agreement, to the Company’s auditors and the audit committee of the Board of Directors of the Company “(i) all significant deficiencies and material weaknesses” in the design or operation of internal controls which are reasonably likely to adversely affect the Company’s ability to record, process, summarize and report financial information and (ii) any fraud, whether or not material, that involves management or other employees who have a significant role in internal controls. The Company has made available to Parent prior to the date of this Agreement a true and complete (in all material respects) summary of any disclosure of the type described in the preceding sentence made by management to the Company’s auditors and audit committee during the period beginning January 1, 2017 and ending as of the date hereof.

23

aggregate, a Material Adverse Effect, (ii) liabilities, obligations or commitments disclosed and provided for in the consolidated balance sheet (or the notes thereto) of the Company and the Company Subsidiaries as of June 30, 2019 and (iii) liabilities, obligations or commitments incurred in the ordinary course of business consistent with past practice since June 30, 2019 that are not material to the Company and the Company Subsidiaries, taken as a whole.

Reg. 46191 (September 10, 1991) or for the FDA or any other Company Regulatory Agency to invoke any similar policy.

Parent has made available to the Company true, correct and complete copies of its and Merger Sub’s Constituent Documents, as amended and in effect on the date of this Agreement, and neither Parent nor Merger Sub is in violation in any material respect of their respective Constituent Documents.

Each Parent Subsidiary is qualified or licensed to do business in each jurisdiction where the ownership, leasing or operation of its properties or assets or conduct of its business requires such qualification or license, except where any failures to be so qualified or licensed have not had and would not reasonably be expected to have, individually or in the aggregate, a Parent Material Adverse Effect. No Parent Subsidiary is in violation in any material respect of its Constituent Documents.

(b) Parent is, directly or indirectly, the record holder and Beneficial Owner of all of the outstanding Securities of each Parent Subsidiary, free and clear of any Liens and free of any other limitation or restriction (including any limitation or restriction on the right to vote, sell, transfer or otherwise dispose of the Securities), except for such restrictions imposed by applicable Law.

41

(b) There are no preemptive or similar rights on the part of any holder of any class of Securities of Parent or any Parent Subsidiary. Neither Parent nor any Parent Subsidiary has any outstanding bonds, debentures, notes or other obligations the holders of which have the right to vote (or which are convertible into or exercisable for Securities having the right to vote) with the holders of any class of Securities of Parent or any Parent Subsidiary on any matter submitted to such holders of Securities.

Section 5.4 Authorization; Board Approval; Voting Requirements.

(a) Each of Parent and Merger Sub has all requisite corporate power and authority to execute and deliver this Agreement, to perform its obligations hereunder and, subject to the Parent Stockholder Approval and the adoption of this Agreement by Parent as the sole stockholder of Merger Sub (which will be effected by Parent as promptly as reasonably practicable after the execution of this Agreement by the Parties), to consummate the Transactions. The execution, delivery and performance of this Agreement and the consummation of the Transactions have been duly and validly authorized by all necessary corporate action, and no other corporate proceedings on the part of either Parent or Merger Sub are necessary for it to authorize this Agreement or to consummate the Transactions, except for, in any such case, the adoption of this Agreement by the Parent Stockholder Approval and the adoption of this Agreement by Parent as the sole stockholder of Merger Sub (which will be effected by Parent as promptly as reasonably practicable after the execution of this Agreement by the Parties). This Agreement has been duly and validly executed and delivered by each of Parent and Merger Sub and, assuming due authorization, execution and delivery by the other Parties, is a legal, valid and binding obligation of each of Parent and Merger Sub, enforceable against each of Parent and Merger Sub in accordance with its terms, subject to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar Laws of general applicability relating to or affecting creditors’ rights and to general equity principles.

(b) None of Parent or Merger Sub is, or at any time since January 1, 2017 has been, an “interested stockholder” of the Company as defined in Section 203 of the DGCL. Neither Parent nor any of the Parent Subsidiaries has taken, or authorized or permitted any of its Representatives to take, any action that would cause Parent or any of its “affiliates” or “associates” (each as defined in Section 203 of Delaware Law) thereof to be deemed an “interested stockholder” as defined in Section 203 of the DGCL

42

or otherwise render Section 251 of the DGCL inapplicable to the Merger. Neither Parent nor any of Parent’s Affiliates directly or indirectly owns, and at all times since January 1, 2017, neither Parent nor any of Parent’s Affiliates has owned, whether Beneficially Owned or otherwise, any Securities of the Company, Equity Rights of the Company or any Contracts convertible into or exercisable or exchangeable for Securities of the Company (through derivative securities or otherwise).

(b) No clearance, consent, approval, Order, license or authorization of, or declaration, registration or filing with, or notice to, or Permit issued by any Governmental Entity or Self-Regulatory Organization is required to be made or obtained by Parent or Merger Sub in connection with the execution or delivery of this Agreement by each of Parent and Merger Sub or the consummation by each of Parent and Merger Sub of the Transactions, except for: (i) compliance by Parent with the HSR Act and the Foreign Competition Laws; (ii) the filing of the Certificate of Merger with the Secretary of State in accordance with the DGCL; (iii) (A) the filing with the SEC of the Joint Proxy Statement/Prospectus in accordance with Regulation 14A promulgated under the Exchange Act, (B) the filing with the SEC, and the declaration of effectiveness under the Securities Act, of the Form S-4 and (C) the filing with the SEC of such reports under and such other compliance with the Exchange Act and the Securities Act as may be required in connection with this Agreement and the Transactions; (iv) such consents, registrations, declarations, notices or filings as are required to be made or obtained under the securities or “blue sky” Laws of various states in connection with the Parent Share Issuance; (v) such filings with and approvals of the Nasdaq Global Market as are required to permit the consummation of the Merger and the listing of the shares of Parent Common Stock to be issued as Merger Consideration; and (vi) any such other clearance, consent, approval, Order, license, authorization, declaration, registration, filing, notice or Permit, the failure of which to make or obtain would not reasonably be expected to have, individually or in the aggregate, a Parent Material Adverse Effect.

Section 5.7 SEC Reports; Parent Financial Statements.

(a) Parent has timely filed or furnished all reports, schedules, forms, statements and other documents required to be filed or furnished by it with or to the SEC since January 1, 2017 (together with all exhibits, financial statements and schedules thereto, all information incorporated therein by reference and all documents filed with the SEC during such period by Parent on a voluntary basis, the “Parent SEC Documents”). As of its filing (or furnishing) date or, if amended prior to the date of this Agreement, as of the date of the last such amendment, each Parent SEC Document complied in all material respects with the applicable requirements of the Exchange Act and the Securities Act, as the case may be. As of its filing date or, if amended prior to the date of this Agreement, as of the date of the last such amendment, each Parent SEC Document filed pursuant to the Exchange Act did not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in

43

order to make the statements made therein, in light of the circumstances under which they were made, not misleading. Each Parent SEC Document that is a registration statement, as amended or supplemented, if applicable, filed pursuant to the Securities Act, as of the date such registration statement or amendment became effective prior to the date of this Agreement, did not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements made therein, in light of the circumstances under which they were made, not misleading.

(b) The Parent Financial Statements, which have been prepared, in all material respects, from the books and records of Parent and the Parent Subsidiaries, comply as to form in all material respects with the applicable accounting requirements and the published rules and regulations of the SEC with respect thereto and have been prepared in accordance with GAAP applied on a consistent basis throughout the periods presented, except as otherwise noted therein. The Parent Financial Statements (including the related notes) present fairly in all material respects the consolidated financial position of Parent and the Parent Subsidiaries as at the respective dates thereof and their consolidated results of operations and cash flows for the periods then ended (subject to normal and recurring year-end audit adjustments in the case of any unaudited interim financial statements.

(c) As of the date hereof, there are no material outstanding or unresolved written comments from the SEC with respect to the Parent SEC Documents. As of the date hereof, none of the Parent SEC Documents are, to the knowledge of Parent, the subject of ongoing SEC review.

(d) The audit committee of the Board of Directors of Parent has established “whistleblower” procedures that meet the requirements of Exchange Act Rule 10A-3, and has delivered or made available to the Company true, complete and correct copies of such procedures in effect as of the date of this Agreement. Since January 1, 2017, neither Parent nor any Parent Subsidiary has received any “complaints” (within the meaning of Exchange Act Rule 10A-3) in respect of any accounting, internal accounting controls or auditing matters. To Parent’s knowledge, since January 1, 2017, no complaint seeking relief under Section 806 of the Sarbanes-Oxley Act has been filed with the United States Secretary of Labor and no employee of Parent or any Parent Subsidiary has threatened to file any such complaint.

(e) To the extent required by the Exchange Act, Parent and the Parent Subsidiaries have established and maintain disclosure controls and procedures (as defined in Rule 13a-15 under the Exchange Act) designed to ensure that material information relating to Parent, including the Parent Subsidiaries, is made known to Parent’s principal executive officer and its principal financial officer by others within those entities, including during the periods in which the periodic reports required under the Exchange Act are being prepared. Each of the principal executive officer of Parent and the principal financial officer of Parent (or each former principal executive officer of Parent and each former principal financial officer of Parent, as applicable) has made all certifications required by Rule 13a-14 or 15d-14 under the Exchange Act and Sections 302 and 906 of the Sarbanes-Oxley Act with respect to the Parent SEC Documents, and the statements contained in such certifications are true and accurate in all material respects as of the date on which they were made. For purposes of this Section 5.7, “principal executive officer” and “principal financial officer” shall have the meanings given to such terms in the Sarbanes-Oxley Act. Since January 1, 2017, Parent has complied in all material respects with the provisions of the Sarbanes-Oxley Act.

(f) Except as has not had and would not reasonably be expected to have, individually or in the aggregate, a Parent Material Adverse Effect, Parent maintains a system of “internal control over financial reporting” (as defined in Rule 13a-15(f) of the Exchange Act) to provide reasonable assurance regarding the reliability of Parent’s financial reporting and the preparation of Parent’s financing statements for external purposes in accordance with GAAP. Parent’s principal executive officer and principal financial officer have disclosed, based on their most recent evaluation of such internal controls prior to the date of this Agreement, to Parent’s auditors and the audit committee of the Board of Directors of Parent “(i) all

44

significant deficiencies and material weaknesses” in the design or operation of internal controls which are reasonably likely to adversely affect Parent’s ability to record, process, summarize and report financial information and (ii) any fraud, whether or not material, that involves management or other employees who have a significant role in internal controls. Parent has made available to the Company prior to the date of this Agreement a true and complete (in all material respects) summary of any disclosure of the type described in the preceding sentence made by management to Parent’s auditors and audit committee during the period beginning January 1, 2017 and ending as of the date hereof.

(g) Neither Parent nor any of the Parent Subsidiaries is a party to, or has any commitment to become a party to, any off-balance sheet joint venture, off-balance sheet partnership or other “off-balance sheet arrangement” (as defined in Item 303(a) of Regulation S-K under the Exchange Act).

Section 5.8 Absence of Undisclosed Liabilities. Parent and the Parent Subsidiaries do not have any liabilities, obligations or commitments, whether or not accrued, known or unknown, contingent or otherwise, that would be required by GAAP to be reflected on the consolidated balance sheet of Parent and the Parent Subsidiaries, except for (i) liabilities, obligations and commitments that have not had and would not reasonably be expected to have, individually or in the aggregate, a Parent Material Adverse Effect, (ii) liabilities, obligations or commitments disclosed and provided for in the consolidated balance sheet (or the notes thereto) of Parent and the Parent Subsidiaries as of June 30, 2019 and (iii) liabilities, obligations or commitments incurred in the ordinary course of business consistent with past practice since June 30, 2019.

(a) (i) Each of Parent and the Parent Subsidiaries holds (A) all authorizations under the FDCA, PHSA, and the regulations of the FDA promulgated thereunder, and (B) authorizations of any applicable Governmental Entity that are concerned with the development, testing, packaging, labeling, storage, import, export, marketing, sale, pricing, use, handling and control, strength, purity, quality, safety, efficacy, reliability, distribution or manufacturing of any of the Parent Products (any such Governmental Entity, a “Parent Regulatory Agency”) necessary for the lawful operation of the businesses of Parent and each of the Parent Subsidiaries as currently conducted (the “Parent Regulatory Permits”); (ii) all such Parent Regulatory Permits are valid and in full force and effect and will continue to be in full force and effect immediately following the Closing; and (iii) Parent and the Parent Subsidiaries are in compliance in all material respects with the terms of all Parent Regulatory Permits.

45

standards. No pre-clinical or clinical testing conducted by or on behalf of Parent or any Parent Subsidiary relating to any Parent Product has been terminated or suspended due to safety or other non-business reasons, and, to the knowledge of Parent, there are no facts that could give rise to such a determination. No Parent Regulatory Agency, clinical investigator, institutional review board or independent monitoring committee has provided notice that it has initiated or, to the knowledge of Parent, threatened to initiate any action to place a hold order on, or otherwise terminate, delay, suspend or modify any such ongoing testing, and, to the knowledge of Parent, there are no facts that would reasonably be expected to give rise to such a determination.

(d) Since January 1, 2017, neither Parent nor any of the Parent Subsidiaries has received any written notice from the FDA or the EMA or any foreign agency with jurisdiction over the development, marketing, labeling, sale, use handling and control, safety, efficacy, reliability or manufacturing of the Parent Products which would reasonably be expected to lead to the denial, limitation, revocation or rescission of any of the Parent Regulatory Permits or of any application for marketing approval currently pending before the FDA or such other Parent Regulatory Agency.

(e) Since January 1, 2017, all reports, documents, claims, Permits and notices required to be filed, maintained or furnished to the FDA or any other Parent Regulatory Agency by Parent and the Parent Subsidiaries have been so filed, maintained or furnished.

Reg. 46191 (September 10, 1991) or for the FDA or any other Parent Regulatory Agency to invoke any similar policy. Since January 1, 2017, (i) neither Parent nor any of the Parent Subsidiaries, nor, to the knowledge of Parent, any officer, employee, agent or distributor of Parent or any of the Parent Subsidiaries, has been debarred or convicted of any crime or engaged in any conduct for which debarment is mandated by 21 U.S.C. § 335a(a) or any similar applicable Law or authorized by 21 U.S.C. § 335a(b) or any similar applicable Law applicable in other jurisdictions in which any of the Parent Products are sold or intended by Parent to be sold; and (ii) neither Parent nor any of the Parent Subsidiaries, nor, to the knowledge of Parent, any officer, employee, agent or distributor of Parent or any of the Parent Subsidiaries, has been excluded from participation in any federal health care program or convicted of any crime or engaged in any conduct for which such Person could be excluded from participating in any federal health care program under Section 1128 of the Social Security Act of 1935 or any similar applicable Law or program.

Neither Parent nor any of the Parent Subsidiaries have received since January 1, 2017 any written notice from any Governmental Entity (including any Parent Regulatory Agency) threatening any, and there is no pending, Proceeding alleging any material violation applicable to any Parent Product by Parent or any of the Parent Subsidiaries of any applicable Law, including any Healthcare Law.

67

Section 7.5 Company No Solicitation.

(a) From the date hereof until the earlier of the Effective Time and the termination of this Agreement pursuant to Section 9.1, except as otherwise set forth in this Section 7.5, the Company shall not, nor shall it authorize or permit any of the Company Subsidiaries to, and the Company shall use reasonable best efforts to cause its and its Subsidiaries’ respective Representatives not to, directly or indirectly (i) initiate or solicit or knowingly facilitate, knowingly induce or knowingly encourage any inquiry or the making of any proposal or offer that constitutes, or would reasonably be expected to lead to, a Takeover Proposal, (ii) enter into, continue or otherwise participate in any discussions or negotiations regarding, furnish to any Person any information or data with respect to, or cooperate in any way that would otherwise reasonably be expected to lead to, any proposal or offer that constitutes, or would reasonably be expected to lead to, any Takeover Proposal, (iii) submit to the stockholders of the Company for their approval or adoption any Takeover Proposal or (iv) agree or publicly announce an intention to take any of the foregoing actions.

The Company shall, and the Company shall cause the Company Subsidiaries and shall use reasonable best efforts to cause its and their respective Representatives to, immediately cease and cause to be terminated any existing activities, discussions or negotiations with any Persons or their Representatives conducted prior to the date of this Agreement with respect to any Takeover Proposal and will request the prompt return or destruction of any confidential information previously furnished to such Persons in connection therewith and immediately terminate the access of each such Person and its Representatives to any electronic data room maintained by or on behalf of the Company or any of the Company Subsidiaries. Neither the Company nor any of the Company Subsidiaries shall modify, amend or terminate, or waive, release, fail to enforce or assign any provisions of, any confidentiality agreement (other than any standstill provision therein) to which it is a party relating to any Takeover Proposal or any inquiry, offer or proposal in connection therewith and shall enforce, to the fullest extent permitted under applicable Law, the provisions of any such agreement (other than any standstill provision therein). Without limiting the foregoing, any violation of the restrictions set forth in this Section 7.5 by any Representative of the Company or any of the Company Subsidiaries shall be deemed to be a breach of this Section 7.5 by the Company.

(b) Notwithstanding the foregoing, prior to receipt of the Company Stockholder Approval, the Company may, in response to a bona fide written Takeover Proposal that was first received after the date hereof, was unsolicited and did not result from a breach of Section 7.5(a):

(i) furnish information with respect to the Company and the Company Subsidiaries to the Person making such Takeover Proposal and its Representatives pursuant to and in accordance with a confidentiality agreement containing provisions no less restrictive in any substantive respect than those contained in the Confidentiality Agreement; provided that such confidentiality agreement need not contain a standstill provision; provided, further, that all such information provided to such Person has previously been provided to Parent or is provided to Parent prior to or substantially concurrently with (and in any event on the same calendar day as) the time it is provided to such Person; and

68

(ii) participate in discussions or negotiations with such Person or its Representatives regarding such Takeover Proposal;

provided, in each case, that the Board of Directors of the Company determines in good faith (after consultation with its outside legal counsel and a financial advisor of nationally recognized reputation), that (i) after consultation with its outside legal counsel and a financial advisor of nationally recognized reputation (it being understood that the Company Financial Advisor is a financial advisor of nationally recognized reputation), such Takeover Proposal is, or would reasonably be expected to lead to, a Superior Proposal and (ii) after consultation with its outside legal counsel, the failure to furnish such information or participate in such discussions or negotiations with respect to such Takeover Proposal would reasonably be expected to be inconsistent with its fiduciary duties under applicable Law.

(c) As promptly as reasonably practicable after the receipt, directly or indirectly, by the Company of any Takeover Proposal or any proposal, offer or inquiry with respect to, or that would reasonably be expected to lead to, any Takeover Proposal, and in any case within 24 hours after the receipt thereof, the Company shall provide oral and written notice to Parent of (i) such Takeover Proposal, proposal, offer or inquiry, (ii) the identity of the Person making any such Takeover Proposal, proposal, offer or inquiry and (iii) the economic and other material terms and conditions of any such Takeover Proposal, proposal, offer or inquiry (including an unredacted copy of all written materials provided by such Person to the Company in connection with such Takeover Proposal, proposal, offer or inquiry and any amendments or modifications thereto). The Company shall promptly (and in any event within 24 hours) keep Parent reasonably informed of any material developments with respect to any such Takeover Proposal, proposal, offer or inquiry (including any material changes thereto and copies of any additional written materials received by the Company, the Company Subsidiaries or their respective Representatives from the Person that submitted such Takeover Proposal or such proposal, offer or inquiry or such Person’s Representatives).

(d) Except as provided in this Section 7.5(d), neither the Board of Directors of the Company nor any committee thereof shall, directly or indirectly, effect a Change in Recommendation. Notwithstanding the foregoing, at any time prior to receipt of the Company Stockholder Approval, the Board of Directors of the Company may, in response to a Superior Proposal (that has not been withdrawn) or an Intervening Event, effect a Change in Recommendation; provided that the Board of Directors of the Company determines in good faith (after consultation with its outside legal counsel and a financial advisor of nationally recognized reputation) that the failure to do so would be inconsistent with its fiduciary duties under applicable Law; provided, further, that the Board of Directors of the Company may not effect such a Change in Recommendation unless:

(i) the Board of Directors of the Company shall have first provided four Business Days’ prior written notice to Parent that it is prepared to effect a Change in Recommendation in response to a Superior Proposal or an Intervening Event (it being understood that delivery of such notice shall not in and of itself constitute a Change in Recommendation), which notice shall (A) in the case of a Superior Proposal, include the material terms and conditions of the Superior Proposal that is the basis of the proposed action of the Board of Directors of the Company (including the identity of the Person making such Superior Proposal and a written summary of any material terms and conditions communicated orally), and shall attach the most current unredacted version of the relevant Alternative Acquisition Agreement (if any) with the Person making such Superior Proposal and unredacted copies of any other documents evidencing or specifying any other terms and conditions of such Takeover Proposal received from, or provided by, the Person making such Superior Proposal and (B) in the case of an Intervening Event, state in reasonable detail the material facts underlying, and the rationale and basis for, the determination that an Intervening Event has occurred (it being understood and agreed that

69

an amendment to the material terms of such Superior Proposal or a material change to the facts and circumstances that are the basis for such Intervening Event shall require an updated notice and a new three Business Day period pursuant to this clause (i) during which period the Company shall be required to comply with this Section 7.5(d) anew with respect to such additional notice);

(ii) during such four Business Day period, the Company and its Representatives, to the extent reasonably requested by Parent, engaged in good faith negotiations with Parent to amend this Agreement in such a manner (A) in the case of a Superior Proposal, that the Takeover Proposal ceases to constitute a Superior Proposal or (B) in the case of an Intervening Event, to obviate the need to effect a Change in Recommendation; and

(iii) after taking into account any revised terms offered in writing by Parent, the Board of Directors of the Company determines in good faith (A) in the case of a Superior Proposal, after consultation with its legal counsel and financial advisor, that such Takeover Proposal continues to constitute a Superior Proposal and (B) in the case of a Superior Proposal or Intervening Event, after consultation with its outside legal counsel, that the failure to make a Change in Recommendation would continue to be inconsistent with its fiduciary duties under applicable Law.

(e) Nothing contained in this Section 7.5 shall prohibit the Company from complying with Rule 14d-9, Rule 14e-2 or Item 1012(a) of Regulation M-A promulgated under the Exchange Act in respect of any Takeover Proposal or making any disclosure to the stockholders of the Company if the Board of Directors of the Company determines in good faith (after consultation with its outside legal counsel) that the failure to make such disclosure would reasonably be expected to be inconsistent with its fiduciary duties under applicable Law; provided, however, that any such action taken or statement made that relates to a Takeover Proposal shall not be deemed to be a Change in Recommendation if the Board of Directors of the Company reaffirms the Company Recommendation in such statement or in connection with such action; provided, further, that neither the Board of Directors of the Company nor any committee thereof shall, except as expressly permitted by Section 7.5(d) (Change in Recommendation), effect a Change in Recommendation.

(f) For purposes of this Agreement:

(i) “Intervening Event” means a Change that is material to the Company and the Company Subsidiaries, taken as a whole, which was not known by, or if known, the effect of which was not reasonably foreseeable by, the Board of Directors of the Company as of or prior to the date hereof (which Change does not relate to a Takeover Proposal), and which becomes known to the Board of Directors of the Company prior to the Company Stockholder Approval; provided, however that none of the following shall constitute, be deemed to contribute to or otherwise be taken into account in determining whether there has been a Intervening Event: (A) any changes in the market price or trading volume of Company Common Stock or Parent Common Stock, in and of itself; (B) the fact that, in and of itself, the Company or any of the Company Subsidiaries exceeds any internal or published projections, forecasts, estimates or predictions in respect of revenues, earnings or other financial or operating metrics for any period ending after the date of this Agreement (it being understood that the underlying facts giving rise or contributing to events described in clauses (A) and (B) may be taken into account in determining whether there has been an Intervening Event if such facts are not otherwise excluded under this definition); (C) any regulatory or clinical Changes relating to any Company Product (including (1) any regulatory actions, requests, recommendations or decisions of any

70

Governmental Entity relating to any Company Product or any other regulatory or clinical development relating to any Company Product, and (2) any clinical trials, studies, tests or results or announcements thereof with respect to any Company Product); and (D) the research, development, testing, distribution, sale, supply, license, marketing, promotion, manufacturing or commercialization of any Company Product.

(ii) “Superior Proposal” means an unsolicited bona fide written Takeover Proposal that was first received after the date hereof that (x) did not result from a breach of Section 7.5 and (y) the Board of Directors of the Company determines, in good faith, after consultation with its outside legal counsel and its financial advisor, (A) is reasonably likely to be consummated in accordance with its terms (if accepted), taking into account all legal, regulatory and financing aspects (including certainty of closing and, to the extent third party financing is required, that such financing is then fully committed on customary terms and conditions) of such Takeover Proposal and the Person making the proposal and other aspects of the Takeover Proposal that the Board of Directors of the Company deems relevant, and (B) if consummated, would result in a transaction more favorable from a financial point of view to the holders of Company Common Stock (solely in their capacity as such) than the Transactions; provided, however, that, for the purposes of this definition of “Superior Proposal,” the term “Takeover Proposal” shall have the meaning assigned to such term herein, except that references to “15%” in such definition shall be deemed to be references to “50%”.

(iii) “Takeover Proposal” means any inquiry, proposal or offer from any Person, other than Parent and the Parent Subsidiaries, relating to any (A) direct or indirect acquisition (whether in a single transaction or a series of related transactions) of assets of the Company or any of the Company Subsidiaries (including Securities of any Company Subsidiaries) equal to 15% or more of the consolidated assets of the Company and the Company Subsidiaries, or to which 15% or more of the revenues of the Company and the Company Subsidiaries on a consolidated basis are attributable for the most recent fiscal year in which audited financial statements are then available, (B) direct or indirect acquisition from the Company or issuance (whether in a single transaction or a series of related transactions) of 15% or more of any class of equity or voting securities of the Company, (C) tender offer or exchange offer that, if consummated, would result in such Person Beneficially Owning 15% or more of any class of equity or voting securities of the Company, or (D) merger, consolidation, share exchange, business combination, joint venture, reorganization, recapitalization, liquidation, dissolution or similar transaction or series of related transactions involving the Company or any of the Company Subsidiaries, under which (1) such Person would, directly or indirectly, acquire assets equal to 15% or more of the consolidated assets of the Company and the Company Subsidiaries, or to which 15% or more of the revenues of the Company and the Company Subsidiaries on a consolidated basis are attributable for the most recent fiscal year in which audited financial statements are then available, or (2) the stockholders or equityholders of such Person immediately after giving effect to such transaction(s) would Beneficially Own 15% or more of any class of equity or voting securities of the Company or the surviving or resulting entity in such transaction(s).

Notwithstanding the foregoing, following the Closing, each Continuing Employee shall participate in Parent’s 401(k) plan on terms substantially comparable with those of similarly situated employees of Parent and Parent shall cause a 401(k) plan sponsored by Parent, the Surviving Corporation or one of their Affiliates to accept rollovers of distributions from the Company’s 401(k) plan to such Continuing Employees to the extent elected by such Continuing Employees and to the extent permitted under applicable law or tax qualification requirements, and such rollovers shall include in-kind rollovers of outstanding loan balances of such Continuing Employees to the extent elected by the Continuing Employees. As of the Closing Date, Parent shall, or shall cause the Surviving Corporation or relevant Affiliate to, credit to Continuing Employees the amount of vacation time that such employees had accrued under any applicable Company Benefit Plans as of the Closing Date.

(b) Except to the extent necessary to avoid the duplication of benefits, the Surviving Corporation shall use commercially reasonable efforts to recognize the service of each Continuing Employee with the Company or its Affiliates before the Effective Time as if such service had been performed with Parent or its Affiliates (i) for purposes of eligibility and vesting under any employee benefit plans (including Parent’s 401(k) plan) and programs of the Parent, of the Surviving Corporation or any of their Affiliates (the “Surviving Corporation Plans”) in which the Continuing Employee participates after the Effective Time, and (ii) for benefit accrual purposes under any Surviving Corporation Plan that is a vacation or severance plan in which the Continuing Employee participates after the Effective Time; provided, that such recognition of service shall not apply for purposes of any plan or arrangement that is a defined benefit pension plan or that is grandfathered or frozen, either with respect to level of benefits or participation or for any post-retirement health or welfare plan.

(c) With respect to any health and welfare plan maintained by the Surviving Corporation or its Affiliates in which Continuing Employees are eligible to participate after the Effective Time, the Surviving Corporation and its Affiliates shall use commercially reasonable efforts to (i) waive all limitations as to preexisting conditions and exclusions with respect to participation and coverage requirements applicable to such employees to the extent such conditions and exclusions were satisfied or did not apply to such employees under the welfare plans maintained by the Company or its Affiliates prior to the Effective Time and (ii) provide each Continuing Employee with credit for any co-payments and deductibles paid prior to the Effective Time in satisfying any analogous deductible or out-of-pocket requirements to the extent applicable under any such plan.

(d) Parent shall, or shall cause the Surviving Corporation or its Affiliates to, assume and honor in accordance with their terms all Company Benefit Plans that are deferred compensation plans, agreements and arrangements, severance and separation pay plans, agreements and arrangements, and written employment, severance, retention, incentive, change in control and termination agreements (including any change in control provisions therein) applicable to employees of the Company, in the same manner and to the same extent that the Company would be required to perform and honor such plans, agreements and arrangements if the transactions contemplated by this Agreement had not been consummated including any right to amend or terminate such plans, agreements and arrangements pursuant to their terms.

(b) Neither Parent nor the Surviving Corporation shall settle, compromise or consent to the entry of any judgment in any threatened or actual Claim for which indemnification could be sought by an Indemnified Person hereunder, unless such settlement, compromise or consent includes an unconditional release of such Indemnified Person from all liability arising out of such Claim or such Indemnified Person otherwise consents in writing to such settlement, compromise or consent. Parent and the Surviving Corporation shall cooperate with an Indemnified Person in the defense of any matter for which such Indemnified Person could seek indemnification hereunder.

From and after the Effective Time, any agreement of any Indemnified Person with the Company or any of its Subsidiaries regarding elimination of liability, indemnification or advancement of expenses shall be assumed by the Surviving Corporation, shall survive the Merger and shall continue in full force and effect in accordance with its terms.

Parent shall, and Parent shall cause the Parent Subsidiaries and shall use reasonable best efforts to cause its and their respective Representatives to, immediately cease and cause to be terminated any existing activities, discussions or negotiations with any Persons or their Representatives conducted prior to the date of this Agreement with respect to any Parent Takeover Proposal and will request the prompt return or destruction of any confidential information previously furnished to such Persons in connection therewith and immediately terminate the access of each such Person and its Representatives to any electronic data room maintained by or on behalf of Parent or any of the Parent Subsidiaries.

Without limiting the foregoing, any violation of the restrictions set forth in this Section 7.19 by any Representative of Parent or any of the Parent Subsidiaries shall be deemed to be a breach of this Section 7.19 by Parent.

(ii) participate in discussions or negotiations with such Person or its Representatives regarding such Parent Takeover Proposal;

provided, in each case, that the Board of Directors of Parent determines in good faith (after consultation with its outside legal counsel and a financial advisor of nationally recognized reputation), that (i) after consultation with its outside legal counsel and a financial advisor of nationally recognized reputation (it being understood that the Parent Financial Advisor is a financial advisor of nationally recognized reputation), such Parent Takeover Proposal is, or would reasonably be expected to lead to, a Parent Superior Proposal and (ii) after consultation with its outside legal counsel, the failure to furnish such information or participate in such discussions or negotiations with respect to such Parent Takeover Proposal would reasonably be expected to be inconsistent with its fiduciary duties under applicable Law.

77

(c) As promptly as reasonably practicable after the receipt, directly or indirectly, by Parent of any Parent Takeover Proposal or any proposal, offer or inquiry with respect to, or that would reasonably be expected to lead to, any Parent Takeover Proposal, and in any case within 24 hours after the receipt thereof, Parent shall provide oral and written notice to the Company of (i) such Parent Takeover Proposal, proposal, offer or inquiry, (ii) the identity of the Person making any such Parent Takeover Proposal, proposal, offer or inquiry and (iii) the economic and other material terms and conditions of any such Parent Takeover Proposal, proposal, offer or inquiry (including an unredacted copy of all written materials provided by such Person to Parent in connection with such Parent Takeover Proposal, proposal, offer or inquiry and any amendments or modifications thereto).

(d) Except as provided in this Section 7.19(d), neither the Board of Directors of Parent nor any committee thereof shall, directly or indirectly, effect a Parent Change in Recommendation. Notwithstanding the foregoing, at any time prior to receipt of the Parent Stockholder Approval, the Board of Directors of Parent may, in response to a Parent Superior Proposal (that has not been withdrawn) or a Parent Intervening Event, effect a Parent Change in Recommendation; provided that the Board of Directors of Parent determines in good faith (after consultation with its outside legal counsel and a financial advisor of nationally recognized reputation) that the failure to do so would be inconsistent with its fiduciary duties under applicable Law; provided, further, that the Board of Directors of Parent may not effect such a Parent Change in Recommendation unless:

(i) the Board of Directors of Parent shall have first provided four Business Days’ prior written notice to the Company that it is prepared to effect a Parent Change in Recommendation in response to a Parent Superior Proposal or a Parent Intervening Event (it being understood that the delivery of such notice shall not in and of itself constitute a Parent Change in Recommendation), which notice shall (A) in the case of a Parent Superior Proposal, include the material terms and conditions of the Parent Superior Proposal that is the basis of the proposed action of the Board of Directors of Parent (including the identity of the Person making such Parent Superior Proposal and a written summary of any material terms and conditions communicated orally), and shall attach the most current unredacted version of the relevant Parent Alternative Acquisition Agreement (if any) with the Person making such Parent Superior Proposal and unredacted copies of any other documents evidencing or specifying any other terms and conditions of such Parent Takeover Proposal received from, or provided by, the Person making such Parent Superior Proposal and (B) in the case of a Parent Intervening Event, state in reasonable detail the material facts underlying, and the rationale and basis for, the determination that a Parent Intervening Event has occurred (it being understood and agreed that an amendment to the material terms of such Parent Superior Proposal or a material change to the facts and circumstances that are the basis for such Parent Intervening Event shall require an updated notice and a new three Business Day period pursuant to this clause (i) during which period Parent shall be required to comply with this Section 7.19(d) anew with respect to such additional notice);

(ii) during such four Business Day period, Parent and its Representatives, to the extent reasonably requested by the Company, engaged in good faith negotiations with the Company to amend this Agreement in such a manner (A) in the case of a Parent Superior Proposal, that the Parent Takeover Proposal ceases to constitute a Parent Superior Proposal or (B) in the case of a Parent Intervening Event, to obviate the need to effect a Parent Change in Recommendation; and

78

(iii) after taking into account any revised terms offered in writing by the Company, the Board of Directors of Parent determines in good faith (A) in the case of a Parent Superior Proposal, after consultation with its legal counsel and financial advisor, that such Parent Takeover Proposal continues to constitute a Parent Superior Proposal and (B) in the case of a Parent Superior Proposal or a Parent Intervening Event, after consultation with its outside legal counsel, that the failure to make a Parent Change in Recommendation would continue to be inconsistent with its fiduciary duties under applicable Law.

(e) Nothing contained in this Section 7.19 shall prohibit Parent from complying with Rule 14d-9, Rule 14e-2 or Item 1012(a) of Regulation M-A promulgated under the Exchange Act in respect of any Parent Takeover Proposal or making any disclosure to the stockholders of Parent if the Board of Directors of Parent determines in good faith (after consultation with its outside legal counsel) that the failure to make such disclosure would reasonably be expected to be inconsistent with its fiduciary duties under applicable Law; provided, however, that any such action taken or statement made that relates to a Parent Takeover Proposal shall not be deemed to be a Parent Change in Recommendation if the Board of Directors of Parent reaffirms the Parent Recommendation in such statement or in connection with such action; provided, further, that neither the Board of Directors of Parent nor any committee thereof shall, except as expressly permitted by Section 7.19(d) (Parent No Solicitation), effect a Parent Change in Recommendation.

(f) For purposes of this Agreement:

(i) “Parent Intervening Event” means a Change that is material to Parent and the Parent Subsidiaries, taken as a whole, which was not known by, or if known, the effect of which was not reasonably foreseeable by, the Board of Directors of Parent as of or prior to the date hereof (which Change does not relate to a Parent Takeover Proposal), and which becomes known to the Board of Directors of Parent prior to the Parent Stockholder Approval; provided, however that none of the following shall constitute, be deemed to contribute to or otherwise be taken into account in determining whether there has been a Parent Intervening Event: (A) any changes in the market price or trading volume of Company Common Stock or Parent Common Stock, in and of itself; (B) the fact that, in and of itself, Parent or any of the Parent Subsidiaries exceeds any internal or published projections, forecasts, estimates or predictions in respect of revenues, earnings or other financial or operating metrics for any period ending after the date of this Agreement (it being understood that the underlying facts giving rise or contributing to events described in clauses (A) and (B) may be taken into account in determining whether there has been a Parent Intervening Event if such facts are not otherwise excluded under this definition); (C) any regulatory or clinical Changes relating to any Parent Product (including (1) any regulatory actions, requests, recommendations or decisions of any Governmental Entity relating to any Parent Product or any other regulatory or clinical development relating to any Parent Product, and (2) any clinical trials, studies, tests or results or announcements thereof with respect to any Parent Product); and (D) the research, development, testing, distribution, sale, supply, license, marketing, promotion, manufacturing or commercialization of any Parent Product.

79

(iii) “Parent Takeover Proposal” means any inquiry, proposal or offer from any Person, other than the Company and the Company Subsidiaries, relating to any (A) direct or indirect acquisition (whether in a single transaction or a series of related transactions) of assets of Parent or any of the Parent Subsidiaries (including Securities of any Parent Subsidiaries) equal to 15% or more of the consolidated assets of Parent and the Parent Subsidiaries, or to which 15% or more of the revenues of Parent and the Parent Subsidiaries on a consolidated basis are attributable for the most recent fiscal year in which audited financial statements are then available, (B) direct or indirect acquisition from Parent or issuance (whether in a single transaction or a series of related transactions) of 15% or more of any class of equity or voting securities of Parent, (C) tender offer or exchange offer that, if consummated, would result in such Person Beneficially Owning 15% or more of any class of equity or voting securities of Parent, or (D) merger, consolidation, share exchange, business combination, joint venture, reorganization, recapitalization, liquidation, dissolution or similar transaction or series of related transactions involving Parent or any of the Parent Subsidiaries, under which (1) such Person would, directly or indirectly, acquire assets equal to 15% or more of the consolidated assets of Parent and the Parent Subsidiaries, or to which 15% or more of the revenues of Parent and the Parent Subsidiaries on a consolidated basis are attributable for the most recent fiscal year in which audited financial statements are then available, or (2) the stockholders or equityholders of such Person immediately after giving effect to such transaction(s) would Beneficially Own 15% or more of any class of equity or voting securities of Parent or the surviving or resulting entity in such transaction(s).

Section 7.20 Credit Facility. The Company shall, and shall cause the Company Subsidiaries to, deliver all customary notices and take all other reasonably necessary actions to facilitate the termination on the Closing Date of all commitments in respect of the Credit Facility, the repayment in full on the Closing Date of all outstanding obligations in respect of the Indebtedness thereunder, and the release on the Closing Date of any Liens securing such Indebtedness and guarantees in connection therewith, in each case pursuant to the delivery to Parent at least three Business Days prior to the Closing of an executed payoff letter with respect to the Credit Facility (the “Payoff Letter”) in form and substance customary for transactions of this type, from the applicable agent on behalf of the persons to whom such Indebtedness is owed, which Payoff Letter together with any related release documentation shall, among other things, include the payoff amount and provide that Liens (and guarantees), if any, granted in connection with the Credit Facility relating to the assets, rights and properties of the Company or any of the Company Subsidiaries securing or relating to such Indebtedness, shall, upon the payment of the amount set forth in the applicable Payoff Letter at or prior to the Effective Time, be released and terminated.

Lantheus to Acquire Progenics to Form a Leading Precision Diagnostics Imaging and Therapeutics Company

Highly Complementary Portfolio of Ultrasound and Radiopharmaceutical Diagnostics and Oncology Therapeutics

Lantheus’ Proven Commercial, Manufacturing and Operational Excellence Well Positioned to Optimize the Combined Company’s Innovative Diagnostic and Radiopharmaceutical Portfolio

Progenics Shareholders to Receive 0.2502 Shares of Lantheus Common Stock for Each Share of Progenics Stock in All-Stock Transaction

Exchange Ratio Represents ~35% Aggregate Ownership Stake in the Combined Company and Implies Premium of 21.5% to Progenics’ 30-Day VWAP¹

Diversifies Revenue Streams, Enhances Cash Flow Generation and Positions Combined Company for Sustainable, Long-Term, Profitable Growth

NORTH BILLERICA, MA and NEW YORK, October 2, 2019 — Lantheus Holdings, Inc. (NASDAQ: LNTH) (“Lantheus”), parent company of Lantheus Medical Imaging, Inc. (“LMI”), a leader in the development, manufacture and commercialization of innovative diagnostic imaging agents and products, and Progenics Pharmaceuticals, Inc. (NASDAQ: PGNX) (“Progenics”), an oncology company developing innovative medicines and artificial intelligence to find, fight and follow cancer, today announced a definitive agreement for Lantheus to acquire Progenics in an all-stock transaction. The transaction has been unanimously approved by the Boards of Directors of both companies.

Under the terms of the agreement, Lantheus Holdings will acquire all of the issued and outstanding common shares of Progenics stock at a fixed exchange ratio. Progenics shareholders will receive 0.2502 shares of Lantheus Holdings stock for each share of Progenics stock, representing approximately a 35% aggregate ownership stake in the combined company. The exchange ratio implies a 21.5% premium to Progenics’ 30-day volume weighted average closing stock price (“VWAP”).¹

Progenics is an oncology company focused on the development and commercialization of innovative targeted medicines and artificial intelligence to find, fight and follow cancer. Progenics takes a leading role in developing diagnostics that help guide physicians and therapeutics that treat patients. The company’s oncology-focused portfolio currently includes three FDA approved products as well as a rich product pipeline. AZEDRA^®, approved in July 2018, is the first and only FDA approved product used to treat adult and pediatric patients 12 years and older for the ultra-orphan indications of pheochromocytoma and paraganglioma. Progenics’ other approved products are oral and subcutaneous formulations of RELISTOR^®, which are licensed to Bausch Health Companies Inc.

The combination of Lantheus and Progenics forms an innovative company with a diversified diagnostic and therapeutics portfolio. The transaction leverages Lantheus’ long-standing expertise in complex manufacturing, supply chain and commercial excellence, with Progenics’ three leading FDA approved products, clinical pipeline and development capabilities. Anchored by Lantheus’ leading microbubble

¹  Based on Progenics’ Volume Weighted Average Closing Stock Price for 30-day period ended October 1, 2019 and Lantheus’ closing price on October 1, 2019.

franchise, the resulting company’s robust portfolio includes additional radiopharmaceutical products for precision diagnostics and therapeutics in the field of oncology as well as a related artificial intelligence platform with a 510(k) approved application in oncology. The two companies had pro forma combined revenue of $370.1 million for the 12 months ended June 30, 2019.

“A long-term pioneer in medical diagnostics, Lantheus remains an industry leader in radiopharmaceuticals as well as the world-wide leader of ultrasound contrast agents. With this combination, we broaden our reach in emerging uses of radioisotopes for precision diagnostics and the exciting and expanding field of radiopharmaceuticals in oncology treatment,” said Mary Anne Heino, President and Chief Executive Officer of Lantheus. “Lantheus will be a leader in radiopharmaceutical innovation, providing medical professionals with essential tools and therapies to diagnose and treat neuroendocrine tumors and prostate cancer patients. Our complementary strengths, radiopharmaceutical manufacturing and supply chain expertise, and focus on commercial execution will deliver sustainable and diversified revenue streams and increase our gross margin potential. We have assessed the strategic fit with Progenics for a number of years and I am pleased that we are finally able to make this combination come to fruition; I believe that the combined company will be well positioned for long-term value creation for all of our stockholders.”

“Today marks the beginning of an exciting new chapter for Progenics. This combination unlocks additional value for stakeholders and stockholders alike through Lantheus’ enhanced resources and R&D capabilities, proven commercial expertise and complementary portfolio of products. The transaction also creates value for Progenics stockholders through a significant premium and the opportunity to participate in the future growth of Lantheus,” said Mark Baker, Chief Executive Officer of Progenics. “Lantheus shares our confidence in the potential of our promising pipeline, and we believe that Lantheus will provide additional commercialization expertise and resources to further advance AZEDRA’s^® launch and deliver substantial revenue growth. This compelling opportunity would not have been possible without the hard work and dedication of our talented employees. We have gotten to know Lantheus’ Board and management team extremely well as we have discussed this combination over the past nine months and we look forward to working together to continue developing innovative products to target diseases and improve treatment for patients around the world.”

Upon completion of the acquisition, which is intended to be tax-free to Progenics’ stockholders for U.S. federal income tax purposes, the combined company will continue to be headquartered in North Billerica, Massachusetts and will trade on the NASDAQ under the ticker symbol: LNTH.

The combined company will be led by Lantheus Chief Executive Officer Mary Anne Heino, who brings 30 years of diverse life sciences industry experience with deep pharmaceutical and operational expertise, including commercializations across complex market channels that will help maximize the success of Progenics’ development pipeline and commercial assets. Ms. Heino will be supported by Chief Financial Officer Robert J. Marshall Jr., CFA, who brings over three decades of finance experience, including in healthcare M&A, capital markets, investor relations and corporate financial planning and analysis, and Chief Operations Officer John Bolla, who has over 22 years of diverse supply chain, global operations and manufacturing experience from pilot to full-scale manufacturing of complex pharmaceutical products. Following the closing, Bradley Campbell, currently a member of Progenics’ Board of Directors, will be added as a member of the Board of Directors of Lantheus Holdings.

Compelling Strategic and Financial Rationale

• Robust portfolio of precision diagnostic and therapeutic products: With complementary strengths and products, the resulting company will serve patients and healthcare professionals across the continuum of critical diagnosis and care. Progenics enhances Lantheus’ R&D platform, combining to form an innovative development portfolio of precision diagnostics and oncology therapeutics.

• Sustainable and diversified revenue growth: This transaction bolsters and diversifies Lantheus’ revenue growth, which is anchored by DEFINITY’s^® continued strong performance and the expansion of its microbubble franchise. The combined company will focus on advancing the successful commercialization of AZEDRA^® to drive revenue growth and on maximizing the value of its development pipeline, which we believe has significant market potential. Supported by Lantheus’ proven manufacturing, supply chain and clinical development expertise in the field of radiopharmaceuticals, the combination is expected to drive enhanced revenue growth over the long term.

• Attractive returns and enhanced cash flow generation potential: Through enhanced revenue growth and significant realizable cost savings opportunities through the elimination of redundant costs and process and scale efficiencies, Lantheus is expected to improve its gross margin profile into the future. The company expects to generate approximately $15 to $20 million in run-rate cost savings by 2022. These savings are related primarily to public company costs and G&A expenses. With improved top line growth, operational execution and synergy opportunities, the transaction is expected to enhance the company’s cash flow generation and be accretive to adjusted and reported EPS by 2022 and 2023, respectively.

• Experienced executive management team: The combined company will be led by a management team with deep experience in the development, manufacturing and commercialization of precision diagnostics and radiopharmaceuticals, and will continue to deploy a team of highly specialized field personnel. The Lantheus Board of Directors is committed to overseeing and incentivizing management to ensure alignment with stockholders’ interests.

Additional Transaction Details

The transaction is expected to close in the first quarter of 2020, subject to approval by Lantheus and Progenics stockholders, regulatory approvals, and customary closing conditions.
