Option Agreement—Change of Control Rights

Under the terms of the Option Agreement, for the twelve-month period beginning on January 8, 2024 (the “Change of Control Rights Period”), the Issuer has agreed not to (i) solicit or encourage any inquiries, offers or proposals for, or that could reasonably be expected to lead to, a proposal, offer or indication of interest relating to any Acquisition Transaction (an “Acquisition Proposal”) from a third party (provided, that ordinary course discussions conducted in good faith with Third Parties regarding Perspective’s scientific programs and the progress of those programs, a Bona Fide Financing (as defined below), potential collaborations and partnerships and other similar matters that are typical of a company like Perspective and do not involve an Acquisition Proposal shall not by themselves constitute solicitation or encouragement ), or (ii) otherwise initiate a process that could reasonably be expected to result in a potential Acquisition Proposal from a third party, in each case, without first notifying Lantheus Alpha (a “ROFO Notice”) and offering Lantheus Alpha the opportunity to submit an offer or proposal to the Issuer for an Acquisition Transaction (as defined below). If Lantheus Alpha fails or declines to submit any such offer within a specified period after the receipt of such ROFO Notice, the Issuer will have the ability to solicit third party Acquisition Proposals. If Lantheus Alpha delivers an Acquisition Proposal to the Issuer, the Issuer and Lantheus Alpha will attempt to negotiate reasonably and in good faith (in the case of the Issuer, on an exclusive basis) the potential terms and conditions for such potential transaction that would result in an Acquisition Transaction for a specified period, which period may be shortened or extended by mutual agreement. Lantheus Alpha can terminate such negotiations at any time in its sole discretion.

In addition, if, during the Change of Control Rights Period, at any time prior to the delivery of a ROFO Notice, the Issuer receives an Acquisition Proposal, the Issuer must promptly notify Lantheus Alpha of the offer, the identity of the third party making such offer and the material terms thereof. If Lantheus Alpha fails or declines to submit a competing offer within a specified period after the receipt of such notice, the Issuer will have the ability to pursue such third-party offer. However, if, during such pursuit, the terms of such third-party offer materially change, the Issuer must notify Lantheus Alpha of such materially changed third-party offer and allow Lantheus Alpha an additional specified period to consider such materially changed third-party offer.

During the Change of Control Rights Period, the Issuer may not enter into (i) any letter of intent, memorandum of understanding, agreement in principle, agreement, contract, commitment (whether or not binding), or other similar agreements with respect to an Acquisition Proposal (subject to certain exceptions) or (ii) any agreement, contract or commitment that could impede the ability of Lantheus Alpha to effect an Acquisition Transaction (a “Competing Instrument”), unless the Issuer promptly notifies Lantheus Alpha within a specified period before entering into a Competing Instrument (which notice must include the identity of the counterparty to such Competing Instrument and the material terms thereof).

“Acquisition Transaction” is defined in the Option Agreement as a transaction or series of related transactions, other than a Bona Fide Financing, involving, directly or indirectly: (a) any acquisition (by asset purchase, stock purchase, merger, license or otherwise) by any Person (as defined therein) or group of any business or assets of the Issuer or any of its subsidiaries (including capital stock of or ownership interest in any subsidiary) that accounted for or generated a certain percentage of the Issuer’s and its subsidiaries’ consolidated assets (by fair market value) or net revenue for the latest preceding specified period for which consolidated financial statements are available, (b) any acquisition of beneficial ownership by any Person or group a certain percentage of the outstanding shares of the Issuer’s Common Stock and any other securities entitled to vote on the election of directors or any tender or exchange offer that if consummated would result in any Person or group beneficially owning a certain percentage of the outstanding shares of the Issuer’s Common Stock and any other securities entitled to vote on the election of directors or (c) any merger, consolidation, share exchange, business combination, recapitalization, liquidation, dissolution or similar transaction involving the Issuer or any of its subsidiaries which would result in any Person or group acquiring beneficial ownership of a certain percentage of the outstanding common stock and other securities entitled to vote on the election of directors of the entity surviving such transaction.

“Bona Fide Financing” means a public or private offering of its equity securities or an “at the market offering” as defined in Rule 415(a)(4) promulgated under the Securities Act of 1933 in which no Person or group acquires equity securities that results in such Person beneficially owning 20% or more of the outstanding capital stock or voting power of Perspective following such transaction.

The rights described in this sub-section are collectively referred to in this Statement as the “Change of Control Rights.”

The foregoing description of the Option Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of such agreement, which is attached as Exhibit 99.3 hereto and incorporated herein by reference.

Registration Rights Agreement

On January 22, 2024, the Issuer and Lantheus Alpha entered into a registration rights agreement (the “Registration Rights Agreement”) in accordance with the requirements of the Investment Agreement, pursuant to which the Issuer agreed to register the resale of the Shares. Under the Registration Rights Agreement, the Issuer has agreed to file a registration statement covering the resale of the Shares no later than the 60^th calendar day following the Closing (the “Filing Deadline”). The Issuer has agreed to use reasonable best efforts to cause such registration statement to become effective as promptly as practicable after the filing thereof but in any event on or prior to the Effectiveness Deadline (as defined in the Registration Rights Agreement), and to keep such registration statement continuously effective until the date the Shares covered by such registration statement have been sold or may be resold pursuant to Rule 144 without restriction. The Issuer has also agreed, among other things, to pay all reasonable fees and expenses (excluding any underwriters’ discounts and commissions and all fees and expenses of legal counsel, accountants and other advisors for Lantheus Alpha except as specifically provided in the Registration Rights Agreement) incident to the performance of or compliance with the Registration Rights Agreement by the Issuer.

The Issuer and Lantheus Alpha granted each other customary indemnification rights in connection with the registration statement. The Issuer made additional customary covenants, including with respect cooperating in underwritten offerings of the Shares and taking steps to allow the Shares to be resold pursuant to Rule 144 under the Securities Act of 1933.

The foregoing description of the Registration Rights Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of such agreement, which is attached as Exhibit 99.4 hereto and incorporated herein by reference.

Except as disclosed in Items 3 and 4 of this Statement, there are no contracts, arrangements, understandings or relationships (legal or otherwise) to which the Reporting Persons are a party with respect to the securities of the Issuer.
