AMENDMENT NO. 1 TO THE TAX RECEIVABLE AGREEMENT
(REORGANIZATION)

August 20, 2021

THIS AMENDMENT NO. 1 (this “Amendment”) to the Tax Receivable Agreement (Reorganization) (as amended, restated or otherwise modified from time to time, the “TRA”), dated as of June 3, 2020, is adopted, executed and entered into by ZoomInfo Technologies Inc. (“PubCo”) and the other thereto. Capitalized terms used but not otherwise defined herein shall have the meanings set forth in the TRA.

WHEREAS, on June 3, 2020, the parties hereto entered into the TRA;

WHEREAS, Section 7.6(b) of the TRA provides that PubCo, with the consent of the other parties hereto, may amend the TRA;

WHEREAS, PubCo and the other parties hereto desire to amend the TRA on the terms and subject to the conditions set forth herein.

NOW THEREFORE, in consideration of the mutual covenants contained herein and in other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto, intending to be legally bound, hereby agrees as follows:

1.Amendments to the TRA

(a)The first sentence of the TRA is hereby deleted in its entirety and replace with the following:

“This TAX RECEIVABLE AGREEMENT (this “Agreement”), is dated as of June 3, 2020, and is between ZoomInfo Technologies Inc., a Delaware corporation, ZoomInfo Intermediate Holdings LLC, a Delaware limited liability company, each of the undersigned parties, and each of the other persons from time to time that becomes a party hereto (each, excluding ZoomInfo Holdings LLC, a Delaware limited liability company (“OpCo”), a “TRA Party” and together the “TRA Parties”).”

(b)The definition of “Corporate Taxpayer” is hereby deleted in its entirety and replaced with the following:

“Corporate Taxpayer” means ZoomInfo Technologies Inc. and any successor corporation and shall include ZoomInfo Intermediate Holdings LLC and any company that is a member of any consolidated Tax Return of which ZoomInfo Technologies Inc. or ZoomInfo Intermediate Holdings LLC is a member.

(c)A new definition for “RKSI Restructuring” is added as follows:

“RKSI Restructuring” means the transactions set forth in the Master Reorganization Agreement dated as of August 20, 2021 between the Corporate Taxpayer and the other parties thereto.

(d)Section 2.2(b) of the TRA is hereby amended by adding a new Section 2.2(b)(ii) as follows:

“(ii)    Notwithstanding anything in this Agreement to the contrary, the amount of any Blocker Transferred Basis or Pre-Merger NOLs attributable to any TRA Party (and the “with and without” methodology for calculations contemplated by this Agreement) shall not be adversely affected to the extent any entity treated as the Corporate Taxpayer transfers Units to another entity treated as the Corporate Taxpayer in a transaction that is tax-free for United States federal income tax purposes or otherwise as a result of the RKSI Restructuring, and the provisions of this Agreement shall be construed accordingly.”

(e)Section 7.11(b) of the TRA is hereby deleted in its entirety and replaced with the following:

(b)    If the Corporate Taxpayer (or any member of a group described in Section 7.11(a)) transfers or is deemed to transfer any Unit or any Reference Asset to a transferee that is treated as a corporation for United States federal income tax purposes (other than the Corporate Taxpayer or a member of a group described in Section 7.11(a)) in a transaction in which the transferee’s basis in the property acquired is determined in whole or in part by reference to such transferor’s basis in such property, then the Corporate Taxpayer shall cause such transferee to assume the obligation to make payments hereunder with respect to the applicable Tax Attributes associated with any Reference Asset or interest therein acquired (directly or indirectly) in such transfer (taking into account any gain recognized in the transaction) in a manner consistent with the terms of this Agreement as the transferee (or one of its Affiliates) actually realizes Tax benefits from the Tax Attributes. If OpCo transfers (or is deemed to transfer for United States federal income tax purposes) any Reference Asset to a transferee that is treated as a corporation for United States federal income tax purposes (other than the Corporate Taxpayer or a member of a group described in Section 7.11(a)) in a transaction in which the transferee’s basis in the property acquired is determined in whole or in part by reference to such transferor’s basis in such property, OpCo shall be treated as having disposed of the Reference Asset in a wholly taxable transaction. The consideration deemed to be received by OpCo in a transaction contemplated in the prior sentence shall be equal to the fair market value of the deemed transferred asset, plus (i) the amount of debt to which such asset is subject, in the case of a transfer of an encumbered asset or (ii) the amount of debt allocated to such asset, in the case of a transfer of a partnership interest. If any member of a group described in Section 7.11(a) that owns any Unit deconsolidates from the group (or the Corporate Taxpayer deconsolidates from the group), then the Corporate Taxpayer shall cause such member (or the parent of the consolidated group in a case where the Corporate Taxpayer deconsolidates from the

2

group) to assume the obligation to make payments hereunder with respect to the applicable Tax Attributes associated with any Reference Asset it owns (directly or indirectly) in a manner consistent with the terms of this Agreement as the member (or one of its Affiliates) actually realizes Tax benefits. If a transferee or a member of a group described in Section 7.11(a) assumes an obligation to make payments hereunder pursuant to either of the foregoing sentences, then the initial obligor is relieved of the obligation assumed.

2.Miscellaneous.

(a)Headings. Section and subsection headings in this Amendment are included herein for convenience of reference only and shall not constitute a part of this Amendment for any other purpose or be given any substantive effect.

(b)No Other Amendments. Except as modified by this Amendment, the TRA shall remain in full force and effect. Nothing herein shall be held to alter, vary or otherwise affect the terms, conditions and provisions of the TRA, other than as expressly contemplated herein.

(c)Controlling Law; Forum. This Acknowledgment and Amendment shall be governed by, and construed in accordance with, the laws of the State of Delaware, without giving effect to any choice of law or conflict of law rules or provisions (whether of the State of Delaware or any other jurisdiction) that would cause the application of the laws of any jurisdiction other than the State of Delaware. Any dispute relating hereto shall be heard in the state or federal courts of Delaware, and the parties agree to exclusive jurisdiction and venue therein and waive any objection based on venue or forum non conveniens with respect to any action instituted therein.

(d)Severability. If any provision of this Amendment shall be held invalid, illegal or unenforceable, the validity, legality or enforceability of the other provisions hereof shall not be affected thereby, and there shall be deemed substituted for the provision at issue a valid, legal and enforceable provision as similar as possible to the provision at issue.

(e)Counterparts. This Amendment may be executed in two or more counterparts, each of which shall be deemed an original and all of which together shall constitute one instrument. Counterparts may be delivered via facsimile, electronic mail (including pdf or any electronic signature complying with the U.S. federal ESIGN Act of 2000, e.g., www.docusign.com) or other transmission method and any counterpart so delivered shall be deemed to have been duly and validly delivered and be valid and effective for all purposes.
