Ladies and Gentlemen:

We have acted as special legal counsel to AEA-Bridges Impact Corp., an exempted company incorporated in the Cayman Islands with limited liability (“ABIC”) and LiveWire Group, Inc., a Delaware corporation (“HoldCo”), in connection with the Registration Statement on Form S-4, initially filed with the U.S. Securities and Exchange Commission (the “Commission”) on February 7, 2022, as amended and supplemented through the date hereof pursuant to the Securities Act of 1933, as amended (the “Act”) (such Registration Statement, as amended or supplemented, is hereafter referred to as the “Registration Statement”), relating to the Business Combination Agreement, dated December 12, 2021 (as it may be amended, supplemented or otherwise modified from time to time, the “Business Combination Agreement” and the transactions contemplated thereby, the “Business Combination”), by and among ABIC, Harley-Davidson, Inc., a Wisconsin corporation (“H-D”), HoldCo, LW EV Merger Sub, Inc., a Delaware corporation (“Merger Sub”), and LiveWire EV, LLC, a Delaware limited liability company (“LiveWire”).

In connection with the Business Combination, (a) at least one day prior to the effectiveness of the merger of Merger Sub with and into ABIC, with ABIC surviving the merger as a wholly owned direct subsidiary of HoldCo (the “Merger”), ABIC will change its jurisdiction of incorporation by deregistering as a Cayman Islands exempted company and continuing and domesticating as a corporation incorporated under the laws of the State of Delaware (“Domesticated ABIC”) (the “Domestication”), and, as a result, (i) all outstanding Class A ordinary shares of ABIC, par value $0.0001 per share, (the “Class A Ordinary Shares”), and Class B ordinary shares of ABIC, par value $0.0001 per share, (the “Class B Ordinary Shares”)

(the Class A Ordinary Shares and Class B Ordinary Shares, collectively, the “ABIC Shares”) will convert into shares of Class A common stock of Domesticated ABIC, par value $0.0001 per share, (the “Domesticated ABIC Common Stock”), (ii) each outstanding warrant included in the units sold in ABIC’s initial public offering (the “ABIC Units”), exercisable for one Class A Ordinary Share at a price of $11.50 per share (the “Public Warrants”) and each outstanding warrant exercisable for one Class A Ordinary Share at a price of $11.50 per share sold to AEA-Bridges Impact Sponsor LLC simultaneously with the closing of ABIC’s initial public offering in a private placement at a price of $1.00 per warrant (the “Private Placement Warrants”) (the Public Warrants and the Private Placement Warrants, collectively, the “ABIC Warrants”) will each convert into a warrant to acquire one share of Domesticated ABIC Common Stock at an exercise price of $11.50 per share of Domesticated ABIC Common Stock (a “Domesticated ABIC Warrant”) and (iii) each issued and outstanding ABIC Unit that has not been previously separated into the underlying Class A Ordinary Share and underlying ABIC Warrant upon the request of the holder thereof will be canceled and will entitle the holder thereof to one share of Domesticated ABIC Common Stock and one-half of one Domesticated ABIC Warrant; (b) on the day of and prior to the Closing, H-D and LiveWire will consummate the separation of the LiveWire business and the other transactions contemplated by the separation agreement into which H-D and LiveWire will enter on the day of the Closing; (c) on the day of and prior to the Closing, the Merger will occur, and as a result (i) each share of Domesticated ABIC Common Stock will be converted on a one-for-one basis into shares of common stock of HoldCo, par value $0.0001 per share, (the “HoldCo Common Stock”) and (ii) each Domesticated ABIC Warrant will convert into a warrant that represents the right to acquire shares of HoldCo Common Stock (a “HoldCo Warrant”); and (d) ElectricSoul, LLC (the “Company Equityholder”) will contribute to HoldCo all of the membership interests of LiveWire (the “Company Equity”) in exchange for the issuance to the Company Equityholder of 161 million shares of HoldCo Common Stock and the right to receive up to an additional 12.5 million shares of HoldCo Common Stock in the future.

This opinion is being rendered in connection with the registration under the above-referenced Registration Statement of (a) 80,500,000 shares of Domesticated ABIC Common Stock, consisting of (i) 40,000,000 shares to be issued to holders of Class A Ordinary Shares, (ii) 10,000,000 shares to be issued to holders of Class B Ordinary Shares and (iii) 30,500,000 shares to be issued upon the exercise of the Domesticated ABIC Warrants (the “Domesticated ABIC Warrant Shares”); (b) 30,500,000 Domesticated ABIC Warrants; (c) 254,000,000 shares of HoldCo Common Stock, consisting of (i) 50,000,000 shares to be issued in exchange for shares of Domesticated ABIC Common Stock, (ii) 161,000,000 shares to be issued to the Company Equityholder in respect of the Company Equity (the “Company Equityholder HoldCo Shares”), (iii) 12,500,000 shares that may be issued as contingent consideration in the Business Combination pursuant to the Business Combination Agreement (the “Company Equityholder HoldCo Earnout Shares”) and (iv) 30,500,000 shares issuable upon exercise by holders of Domesticated ABIC Warrants following the Domestication (the “HoldCo Warrant Shares”); and (d) 30,500,000 HoldCo Warrants.

Our opinions expressed above are subject to the qualifications that we express no opinion as to the applicability of, compliance with, or effect of (i) any bankruptcy, insolvency, reorganization, fraudulent transfer, fraudulent conveyance, moratorium or other similar law or judicially developed doctrine in this area (such as substantive consolidation or equitable subordination) affecting the enforcement of creditors’ rights generally, (ii) general principles of equity (regardless of whether enforcement is considered in a proceeding in equity or at law), (iii) an implied covenant of good faith and fair dealing, (iv) public policy considerations which may limit the rights of parties to obtain certain remedies, (v) any requirement that a claim with respect to any security denominated in other than U.S. dollars (or a judgment denominated in other than U.S. dollars in respect of such claim) be converted into U.S. dollars at a rate of exchange prevailing on a date determined in accordance with applicable law, (vi) governmental authority to limit, delay or prohibit the making of payments outside of the United States or in a foreign currency or currency unit and (vii) any laws except the laws of the State of New York and the DGCL. We advise you that issues addressed by this letter may be governed in whole or in part by other laws, but we express no opinion as to whether any relevant difference exists between the laws upon which our opinions are based and any other laws which may actually govern. We do not find it necessary for the purposes of this opinion, and accordingly we do not purport to cover herein, the application of the securities or “Blue Sky” laws of the various states to the issuance of the Securities.
