Immediately upon the completion of the Business Combination and the other transactions contemplated by the Business Combination Agreement (the “Transactions”, and such completion, the “Closing”), Open Lending became a direct wholly-owned subsidiary of ParentCo. In connection with the Transactions, ParentCo changed its

name to Open Lending Corporation (the Company). In connection with the Transactions, Bregal Sagemount received 14,278,604 shares of Common Stock, and Bregal Investments received 26,071 shares of Common Stock. Additionally, on July 21, 2020 and August 11, 2020, Bregal Sagemount received 4,039,702 and 2,019,851 shares of Common Stock, respectively, and Bregal Investments received 7,376 and 3,688 shares of Common Stock, respectively, in each case as contingency consideration pursuant to the earnout rights set forth in the Business Combination Agreement that provided for the issuance of such additional shares if the Company’s stock traded at certain levels following the Closing.

Investors Rights Agreement

In connection with the Transactions, Open Lending, Nebula, ParentCo, certain persons and entities holding membership units of Open Lending (including Blocker Holder and Bregal Investments) and certain persons and entities holding founder shares of Nebula (collectively, the “Investor Holders”), entered into the Investor Rights Agreement (the “Investors Rights Agreement”) at the Closing. Pursuant to the Investor Rights Agreement, until the fifth (5th) anniversary of the Closing, at each annual or special meeting of stockholders of the Company, Blocker Holder has the right to designate for election as a director of the Company, and the board of directors of the Company (including any committee thereof) shall nominate (and recommend for election and include such recommendation in a timely manner in any proxy statement, consent solicitation or other applicable announcement to the Company’s stockholders): (i) one (1) individual to serve as a Class I Director of the Company; and (ii) one (1) individual to serve as a Class II Director of the Company; provided, however, that if any time during such five-year period, Blocker Holder owns less than 8,000,000 shares of Common Stock but more than 4,000,000 shares of Common Stock (in each case, as adjusted for any share split, share dividend or other share recapitalization, share exchange or other event), the foregoing will apply only to one (1) individual to serve as a Class I Director of the Company (collectively, the “Blocker Holder Designation Rights”), and if at any time during such five-year period Blocker Holder owns less than 4,000,000 shares of Common Stock (as adjusted for any share split, share dividend or other share recapitalization, share exchange or other event), the rights of Blocker Holder and obligations of the Company with respect to the Blocker Holder Designation Rights shall terminate.

Pursuant to the terms of the Investor Rights Agreement, the Company is obligated to file a registration statement to register the resale of certain securities of the Company held by the Investor Holders. In addition, pursuant to the terms of the Investor Rights Agreement and subject to certain requirements and customary conditions, including with regard to the number of demand rights that may be exercised, the Investor Holders may demand at any time or from time to time, that the Company file a registration statement on Form S-1, or any similar long-form registration statement, or if available, on Form S-3 to register the shares of common stock of the Company held by such holders. The Investor Rights Agreement also provides the Blocker Holder with “piggy-back” registration rights, subject to certain requirements and customary conditions. The Investor Rights Agreement further provides for the Company’s Common Stock held by such holders to be locked-up for 180 days after the Closing Date.

A copy of the Investors Rights Agreement is filed as an exhibit hereto and is incorporated herein by reference.

Tax Receivable Agreement

In connection with the Closing, the Company entered into a Tax Receivable Agreement, dated as of the Closing Date, with Nebula, the Blocker, the Blocker Holder, and Open Lending. Prior to the Closing, (i) 100% of the interest in Open Lending was held by the Blocker and certain other persons (the “Company Unit Sellers”) and (ii) 100% of the Blocker was held by the Blocker Holder. The Tax Receivable Agreement generally provides for the payment by the Company to the Company Unit Sellers and Blocker Holder, as applicable, of 85% of the net cash savings, if any, in U.S. federal, state and local income tax that the Company actually realizes (or is deemed to realize in certain circumstances) in periods after the Closing as a result of: (i) certain tax attributes of Blocker and/or Open Lending that existed prior to the Business Combination and were attributable to the Blocker; (ii) certain increases in the tax basis of Open Lending assets resulting from the second merger of the Transactions; (iii) imputed interest deemed to be paid by the Company as a result of payments the Company makes under the Tax Receivable Agreement; and (iv) certain increases in tax basis resulting from payments Nebula makes under the Tax Receivable Agreement.
