This Promissory Note is executed in connection with the purchase by the Maker of certain equity interests in Innervate Radiopharmaceuticals LLC (all such interests and any proceeds thereof (the “Collateral”).

For the avoidance of doubt, no interest shall accrue on any portion of the Maximum Principal Amount that has not been advanced to the Maker. Following the occurrence and during the continuance of any Event of Default, as defined below, the interest rate otherwise applicable pursuant to this Section 1 shall be increased, at Payee’s election, by five percent (5%) (the “Default Rate”).

2. PAYMENT OF INTEREST AND PRINCIPAL. The entire outstanding Principal Amount and accrued interest shall be due and payable on the earlier of (i) an Event of Default, or (ii) the fifth (5^th) anniversary of the Effective Date (such date, the “Maturity Date”), provided, such Maturity Date may be extended by mutual agreement in writing by Maker and Payee.

3. ADVANCES. From and after the Effective Date and until the Maturity Date, the Payee may, in its discretion, make one or more loan advances to the Maker (each, an “Advance”) in such amounts and at such times as the Payee and the Maker may agree, provided that the aggregate principal amount of all Advances outstanding hereunder shall not at any time exceed the Maximum Principal Amount. Each Advance shall be evidenced by this Promissory Note and shall be recorded by the Payee on a grid maintained by the Payee (or otherwise in the Payee’s books and records), which recordation shall, absent manifest error, constitute conclusive evidence of the date and amount of each Advance and of the outstanding Principal Amount; provided that any failure to make, or error in making, any such recordation shall not affect the obligations of the Maker to repay the Principal Amount, together with accrued interest thereon, in accordance with the terms hereof. Amounts repaid hereunder may not be reborrowed.

4. PREPAYMENT. This Promissory Note may be prepaid in whole or in part at any time. Any prepayment shall first be applied to accrued interest, and then to Principal Amount.

5. EVENTS OF DEFAULT BY THE MAKER. If any of the following events (“Events of Default”) shall occur:

(iii) The appointment of a receiver for Maker by a court of competent jurisdiction, which appointment shall not have been vacated within a period of forty-five (45) days after the date of appointment;

(iv) Maker breaches any of its covenants or agreements set forth in this Promissory Note;

(v) Maker undergoes a merger, dissolution, liquidation or consolidation of Maker (including with or into another person), or the sale, transfer, license, lease or other disposition of (whether in one transaction or in a series of transactions) any material portion of Maker’s assets (other than the Collateral); provided that, notwithstanding the foregoing, a sale, transfer or other disposition of all or any portion of the Collateral shall not constitute an Event of Default if (A) Maker provides Payee with not less than ten (10) business days’ prior written notice of such proposed disposition (including reasonable detail as to the proposed terms and the expected net cash proceeds) and obtains the prior written consent of Payee to such disposition, which consent shall not be unreasonably withheld if such disposition is to an unaffiliated third party at arm’s length for fair market value as reasonably determined by Payee, and (B) the net cash proceeds of such disposition are applied, concurrently with the closing thereof, to prepay the outstanding Principal Amount and accrued and unpaid interest hereunder in accordance with Section 4 (Prepayment), with any remaining proceeds released to Maker only after such application;

then, the entire outstanding Principal Amount together with all accrued interest thereon shall immediately with no further action become due and payable.
