(the “Investor”) of $6,000,000 (the “Purchase Amount”) on or about June 24, 2020, Pandion Therapeutics Holdco LLC, a Delaware limited liability company (the “Company”), issues to the Investor the right to certain of the Company’s Capital Shares, subject to the terms described below.

1. Events

(a)    Equity Financing. If there is an Equity Financing before the termination of this Safe, on the initial closing of such Equity Financing, this Safe will automatically convert into the number of Standard Preferred Shares equal to the Purchase Amount divided by the price per share of the Standard Preferred Shares.

In connection with the automatic conversion of this Safe into Standard Preferred Shares, the Investor will execute and deliver to the Company all of the transaction documents related to the Equity Financing,provided, that such documents are the same documents to be entered into with the purchasers of Standard Preferred Shares.

(b)    Initial Public Offering. If there is an Initial Public Offering prior to March 31, 2021 and before the termination of this Safe, on the closing of such Initial Public Offering, this Safe will automatically convert into the number of Common Shares equal to the quotient obtained from dividing the Purchase Amount divided by the IPO Price.

(c)    Change of Control. If there is a Change of Control before the termination of this Safe, this Safe will automatically be entitled (subject to the liquidation priority set forth in Section 1(f) below) to receive a portion of Proceeds, due and payable to the Investor immediately prior to, or concurrent with, the consummation of such Change of Control, equal to the greater of (i) the Purchase Amount (the “Cash-Out Amount”) or (ii) the amount payable on the number of Common Shares equal to the Purchase Amount divided by the Liquidity Price (the “Conversion Amount”). If any of the Company’s securityholders are given a choice as to the form and amount of Proceeds to be received in a Change of Control, the Investor will be given the same choice,providedthat the Investor may not choose to receive a form of consideration that the Investor would be ineligible to receive as a result of the Investor’s failure to satisfy any requirement or limitation generally applicable to the Company’s securityholders, or under any applicable laws.

Notwithstanding the preceding paragraph, if there is a Change of Control prior to April 1, 2021 and before the termination of this Safe, immediately prior to such Change of Control, the Investor may elect to convert this Safe into that number of the Company’s Series B Preferred Shares (the “Series B Preferred Shares”) equal to the quotient obtained by dividing the Purchase Amount by the Original Issue Price (as defined in the Company’s Amended and Restated Operating Agreement, dated as of March 23, 2020, as amended, the “Operating Agreement”) of the Series B Preferred Shares (the “Optional Conversion Price”).

Notwithstanding the foregoing, in connection with a Change of Control intended to qualify as atax-free reorganization, the Company may reduce the cash portion of Proceeds payable to the Investor by the amount determined by its Board of Directors (the “Board”) in good faith for such Change of Control to qualify as atax-free reorganization for U.S. federal income tax purposes, provided that such reduction (A) does not reduce the total Proceeds payable to such Investor and (B) is applied in the same manner and on a pro rata basis to all securityholders who have equal priority to the Investor under Section 1(f).

(d)    Optional Conversion. If this Safe remains outstanding on or after April 1, 2021, the Investor may elect to convert this Safe into that number of Series B Preferred Shares equal to the quotient obtained by dividing the Purchase Amount by the Optional Conversion Price.

(e)     Dissolution Event. If there is a Dissolution Event before the termination of this Safe, the Investor will automatically be entitled (subject to the liquidation priority set forth in Section 1(f) below) to receive a portion of Proceeds equal to theCash-Out Amount, due and payable to the Investor immediately prior to the consummation of the Dissolution Event.

(f)    Liquidation Priority. In a Change of Control in which the Investor does not elect to convert this Safe into Series B Preferred Shares or a Dissolution Event, this Safe is intended to operate like standardnon-participating preferred shares.

(iii)    Senior to payments for Common Shares.

The Investor’s right to receive its Conversion Amount is (A) on par with payments for Common Shares and other Safes and/or preferred shares who are also receiving Conversion Amounts or Proceeds on a similaras-converted to Common Shares basis, and (B) junior to payments described in clauses (i) and (ii) above (in the latter case, to the extent such payments areCash-Out Amounts or similar liquidation preferences).

(g)    Termination. This Safe will automatically terminate immediately following the earliest to occur of: (i) the issuance of Capital Shares to the Investor pursuant to the automatic conversion or optional conversion of this Safe under Sections 1(a), 1(b), 1(c) and 1(d); or (ii) the payment, or setting aside for payment, of amounts due the Investor pursuant to Section 1(c) or Section 1(e).
