(hh) The Company and its Subsidiaries are insured by insurers of recognized financial responsibility against such losses and risks and in such amounts as are, in the reasonable judgment of the ZoomInfo Parties, prudent and customary in the businesses in which they are engaged; none of the Company or any of its Subsidiaries has been refused any insurance coverage sought or applied for; and none of the Company or any of its Subsidiaries has any reason to believe that it will not be able to renew its existing insurance coverage as and when such coverage expires or to obtain similar coverage from similar insurers as may be necessary to continue its business, in each case other than as would not, singly or in the aggregate, have a Material Adverse Effect.

(ii) The Company and its Subsidiaries, taken as a whole, possess all licenses, certificates, authorizations and permits issued by, and has made all declarations and filings with, the appropriate federal, state or foreign regulatory authorities necessary to conduct their respective businesses, except where the failure to obtain such licenses, certificates, authorizations and permits, or make such declarations and filings, would not, singly or in the aggregate, have a Material Adverse Effect; and none of the Company or any of its Subsidiaries has received any notice of proceedings relating to the revocation or modification of any such license, certificate, authorization or permit or has any reason to believe that any such license, certificate, authorization or permit will not be renewed in the ordinary course, which, singly or in the aggregate, if the subject of an unfavorable decision, ruling or finding, would have a Material Adverse Effect.

All disclosures included in the Registration Statement, the Time of Sale Prospectus and the Prospectus regarding “non-GAAP financial measures” (as such term is defined by the rules and regulations of Commission) comply in all material respects with Regulation G of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and Item 10 of Regulation S-K of the Securities Act, to the extent applicable. The pro forma financial statements and the related notes thereto included in the Registration Statement, the Time of Sale Prospectus and the Prospectus present fairly in all material respects the information shown therein and have been prepared in all material respects in accordance with the Commission’s rules and guidelines with respect to pro forma financial statements and have been properly compiled on the bases described therein, and the assumptions used in the preparation thereof are reasonable and the adjustments used therein are appropriate to give effect to the transactions and circumstances referred to therein.

(ll) The Company and its Subsidiaries on a consolidated basis maintain a system of “internal control over financial reporting” (as defined in Rule 13a-15(f) of the Exchange Act) that has been reasonably designed by, or

(pp) The Company and each of its Subsidiaries have filed all federal, state, local and foreign tax returns required to be filed and have paid all taxes required to be paid by them (except for cases in which the failure to file would not, singly or in the aggregate, have a Material Adverse Effect, except as currently being contested in good faith and for which reserves required by U.S. GAAP have been created in the financial statements of the ZoomInfo Parties), and no tax deficiency has been determined adversely to the Company or any of its Subsidiaries which, singly or in the aggregate, has had (nor, to the knowledge of the Company or any of its Subsidiaries, has any tax deficiency assessment which could reasonably be expected to be determined adversely to the Company or its Subsidiaries been threatened that would have) a Material Adverse Effect.

(qq) The interactive data in eXtensible Business Reporting Language included in the Registration Statement fairly presents the information called for in all material respects and has been prepared in accordance with the Commission’s rules and guidelines applicable thereto.

Registration Statement, the Time of Sale Prospectus or the Prospectus, complied in all material respects with the Securities Act and did not as of its date and, when taken together with the Time of Sale Prospectus, at the time of each sale of the Shares in connection with the offering when the Prospectus is not yet available to prospective purchasers, contain any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

(tt) No forward-looking statement (within the meaning of Section 27A of the Securities Act and Section 21E of the Exchange Act) included in the Registration Statement, the Time of Sale Prospectus or the Prospectus has been made or reaffirmed without a reasonable basis or has been disclosed other than in good faith.

Such firm shall be designated in writing by the Representatives, in the case of parties indemnified pursuant to Section 10(a) or 10(b) hereof, by the Company, in the case the ZoomInfo Parties, the Company’s directors, the Company’s officers who sign the Registration Statement and each person, if any, who controls the Company within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act, and by the Selling Stockholders, in the case of the Selling Stockholders and each person, if any, who controls any Selling Stockholder within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act. The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement (x) includes an unconditional release of such indemnified party, in form and substance satisfactory to such indemnified party, from all liability on claims that are the subject matter of such proceeding and (y) does not include any statements to, or any admission of, fault, culpability or failure to act by or on behalf of any indemnified party.

(e)To the extent the indemnification provided for in Section 10(a), 10(b) or 10(c) hereof is unavailable to an indemnified party or insufficient in respect of any losses, claims, damages or liabilities referred to therein (other than by virtue of the failure of an indemnified party to notify the indemnifying party of its right to indemnification pursuant to subsection (d) above, where such failure materially prejudices the indemnifying party (through the forfeiture of substantial rights or defenses)), then each indemnifying party under such paragraph, in lieu of indemnifying such indemnified party thereunder, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the indemnifying party or parties, on the one hand, and the indemnified party or parties, on the other hand, from the offering of the Shares or (ii) if the allocation provided by clause 10(e)(i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause 10(e)(i) above but also the relative fault of the indemnifying party or parties, on the one hand, and the indemnified party or parties, on the other hand, in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the indemnifying party or parties, on the one hand, and the indemnified party or parties, on the other hand, in connection with the offering of the Shares shall be deemed to be in the same respective proportions as the net proceeds from the offering of the Shares (before deducting expenses) received by the Selling Stockholders and the total underwriting discounts and commissions received by the Underwriters, in each case as set forth in the table on the cover of the Prospectus, bear to the aggregate Public Offering Price of the Shares. The relative fault of the indemnifying party or parties, on the one hand, and the indemnified party or parties, on the other hand, shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by a ZoomInfo Party, a Selling Stockholder or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Underwriters’ respective obligations to contribute pursuant to this Section 10 are several in proportion to the respective number of Shares they have purchased hereunder, and not joint. The aggregate liability of each Selling Stockholder under the contribution agreement contained in this paragraph and the indemnification agreement contained in this Section 10 shall be limited to such Selling Stockholder’s Selling Stockholder Proceeds.

(f)The ZoomInfo Parties, the Selling Stockholders and the Underwriters agree that it would not be just or equitable if contribution pursuant to this Section 10 was determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in Section 10(e) hereof. The amount paid or payable by an indemnified party as a

result of the losses, claims, damages and liabilities referred to in Section 10(e) hereof shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 10, no Underwriter shall be required to contribute any amount in excess of the amount by which the total underwriting discounts and commissions received by such Underwriter with respect to the offering of the Shares exceeds the amount of any damages that such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The remedies provided for in this Section 10 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any indemnified party at law or in equity. The aggregate liability of each Selling Stockholder under the indemnification and contribution agreements contained in this Section 10 shall be limited to such Selling Stockholder’s Selling Stockholder Proceeds.

(g)The indemnity and contribution provisions contained in this Section 10, the agreements regarding expense reimbursement and the representations, warranties and other statements made by or on behalf of any ZoomInfo Party or any Selling Stockholder contained in this Agreement or any certificate delivered pursuant hereto shall remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation made by or on behalf of any Underwriter or its director, officers or employees, any person controlling any Underwriter or any affiliate of any Underwriter, by or on behalf of the any ZoomInfo Party, the Company’s officers or directors or any person controlling the Company, or by or on behalf of any Selling Stockholder or any person controlling any Selling Stockholder and (iii) acceptance of and payment for any of the Shares.

11.Termination. The Underwriters may terminate this Agreement by notice given by you to the Company, if after the execution and delivery of this Agreement and on or prior to the Closing Date (a) trading generally shall have been suspended or materially limited on, or by, as the case may be, any of the Exchange or the New York Stock Exchange, (b) trading of any securities of the Company shall have been suspended on any exchange or in any over-the-counter market, (c) a material disruption in securities settlement, payment or clearance services in the United States shall have occurred, (d) any moratorium on commercial banking activities shall have been declared by Federal or New York State authorities or (e) there shall have occurred any outbreak or escalation of hostilities, or any change in financial markets or any calamity or crisis that, in your judgment, is material and adverse and which, singly or together with any other event specified in this clause (e), makes it, in your judgment, impracticable or inadvisable to

proceed with the offer, sale or delivery of the Shares on the terms and in the manner contemplated by this Agreement, the Time of Sale Prospectus or the Prospectus.

12.Effectiveness; Defaulting Underwriters.

(a)This Agreement shall become effective upon the execution and delivery hereof by the parties hereto.

(b)If, on the Closing Date or the Option Closing Date, as the case may be, any Underwriter defaults on its obligation to purchase the Shares that it has agreed to purchase hereunder on such date, the non-defaulting Underwriters may in their discretion arrange for the purchase of such Shares by other persons satisfactory to the Company and the Selling Stockholders on the terms contained in this Agreement. If, within 36 hours after any such default by any Underwriter, the non-defaulting Underwriters do not arrange for the purchase of such Shares, then the Company and the Selling Stockholders shall be entitled to a further period of 36 hours within which to procure other persons satisfactory to the non-defaulting Underwriters to purchase such Shares on such terms. If other persons become obligated or agree to purchase the Shares of a defaulting Underwriter, either the non-defaulting Underwriters or the Company or the Selling Stockholders may postpone the Closing Date or the Option Closing Date, as the case may be, for up to seven days in order to effect any changes that in the opinion of counsel for the Company, counsel for the Underwriters or counsel for any of the Selling Stockholders may be necessary in the Registration Statement and the Prospectus or in any other document or arrangement, and the Company agrees to promptly prepare any amendment or supplement to the Registration Statement and the Prospectus that effects any such changes. As used in this Agreement, the term “Underwriter” includes, for all purposes of this Agreement unless the context otherwise requires, any person not listed in Schedule II hereto that, pursuant to this Section 12, purchases Shares that a defaulting Underwriter agreed but failed to purchase.

(c)If, after giving effect to any arrangements for the purchase of the Shares of a defaulting Underwriter or Underwriters by the non-defaulting Underwriters, the Company and the Selling Stockholders as provided in paragraph (b) above, the aggregate number of Shares which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase is not more than one-tenth of the aggregate number of the Shares to be purchased on such date, the other Underwriters shall be obligated severally in the proportions that the number of Firm Shares set forth opposite their respective names in Schedule II hereto bears to the aggregate number of Firm Shares set forth opposite the names of all such non-defaulting Underwriters, or in such other proportions as you may specify, to purchase the Shares which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase on such date for which arrangements have not been made; provided that in no event shall the number of

Shares that any Underwriter has agreed to purchase pursuant to this Agreement be increased pursuant to this Section 12 by an amount in excess of one-ninth of such number of Shares without the written consent of such Underwriter. If, on the Closing Date, after giving effect to any arrangements for the purchase of the Shares of a defaulting Underwriter or Underwriters by the non-defaulting Underwriters, the Company and the Selling Stockholders as provided in paragraph (b) above, the aggregate number of Firm Shares with respect to which such default occurs is more than one-tenth of the aggregate number of Firm Shares to be purchased on the Closing Date, this Agreement shall terminate without liability on the part of any non-defaulting Underwriter, any ZoomInfo Party or any Selling Stockholder, except that the Company will continue to be liable for the payment of expenses as set forth in paragraph (d) below and Section 7(j) hereof and except that the provisions of Section 10 hereof shall not terminate and shall remain in effect. If, on an Option Closing Date, after giving effect to any arrangements for the purchase of the Shares of a defaulting Underwriter or Underwriters by the non-defaulting Underwriters, the Company and the Selling Stockholders as provided in paragraph (b) above, the aggregate number of Additional Shares with respect to which such default occurs is more than one-tenth of the aggregate number of Additional Shares to be purchased on such Option Closing Date, the non-defaulting Underwriters shall have the option to (i) terminate their obligation hereunder to purchase the Additional Shares to be sold on such Option Closing Date or (ii) purchase not less than the number of Additional Shares that such non-defaulting Underwriters would have been obligated to purchase in the absence of such default. Any action taken under this paragraph shall not relieve any defaulting Underwriter from liability in respect of any default of such Underwriter under this Agreement.

(d)If this Agreement shall be terminated by the Underwriters, or any of them, because of any failure or refusal on the part of any ZoomInfo Party or any Selling Stockholder to comply with the terms or to fulfill any of the conditions of this Agreement required to be complied with or fulfilled by the ZoomInfo Parties or the Selling Stockholders, or if for any reason any ZoomInfo Party or any Selling Stockholder shall be unable to perform its obligations under this Agreement (other than, with respect to a defaulting Underwriter, by reason of a default by such Underwriter or the occurrence of any of the events described in clauses (a), (c), (d) or (e) of Section 11), the ZoomInfo Parties will reimburse the Underwriters or such Underwriters as have so terminated this Agreement with respect to themselves, severally, for all out-of-pocket expenses (including the reasonable and documented fees and disbursements of their counsel) reasonably incurred by such Underwriters in connection with this Agreement or the offering contemplated hereunder.

13.Entire Agreement. (a) This Agreement, together with any contemporaneous written agreements and any prior written agreements (to the extent not superseded by this Agreement) that relate to the offering of the Shares, represents the

entire agreement between the ZoomInfo Parties and the Selling Stockholders, on the one hand, and the Underwriters, on the other hand, with respect to the preparation of any preliminary prospectus, the Time of Sale Prospectus, the Prospectus, any free writing prospectus, any Written Testing-the-Waters Communication, the conduct of the offering and the purchase and sale of the Shares.

(b)Each ZoomInfo Party and each Selling Stockholder acknowledges that, in connection with the offering of the Shares: (i) the Underwriters have acted at arm’s length, are not agents of, and owe no fiduciary duties to, any ZoomInfo Party, any Selling Stockholder or any other person; (ii) the Underwriters owe the ZoomInfo Parties and the Selling Stockholders only those duties and obligations set forth in this Agreement, any contemporaneous written agreements and prior written agreements (to the extent not superseded by this Agreement), if any; (iii) none of the activities of the Underwriters in connection with the transactions contemplated herein constitutes a recommendation, investment advice or solicitation of any action by the Underwriters with respect to any entity or natural person; and (iv) the Underwriters may have interests that differ from those of the ZoomInfo Parties and/or the Selling Stockholders. Each ZoomInfo Party and each Selling Stockholder waives to the full extent permitted by applicable law any claims it may have against the Underwriters arising from an alleged breach of fiduciary duty in connection with the offering of the Shares.

(c)Each Selling Stockholder further acknowledges and agrees that, although the Underwriters may provide certain Selling Stockholders with certain Regulation Best Interest and Form CRS disclosures or other related documentation in connection with the offering, the Underwriters are not making a recommendation to any Selling Stockholder to participate in the offering or sell any Shares at the Purchase Price, and nothing set forth in such disclosures or documentation is intended to suggest that any Underwriter is making such recommendation.

(d)This Agreement shall inure to the benefit of and be binding upon the parties hereto and their respective successors and the officers and directors and any controlling persons referred to herein, and the affiliates of each Underwriter referred to in Section 10 hereof. Nothing in this Agreement is intended or shall be construed to give any other person any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision contained herein. No purchaser of Shares from any Underwriter shall be deemed to be a successor merely by reason of such purchase.

14.Recognition of the U.S. Special Resolution Regimes. (a) In the event that any Underwriter that is a Covered Entity becomes subject to a proceeding under a U.S. Special Resolution Regime, the transfer from such Underwriter of this Agreement, and any interest and obligation in or under this Agreement, will be effective to the same extent as the transfer would be effective under the U.S. Special Resolution Regime if this

Agreement, and any such interest and obligation, were governed by the laws of the United States or a state of the United States.

(b)In the event that any Underwriter that is a Covered Entity or a BHC Act Affiliate of such Underwriter becomes subject to a proceeding under a U.S. Special Resolution Regime, Default Rights under this Agreement that may be exercised against such Underwriter are permitted to be exercised to no greater extent than such Default Rights could be exercised under the U.S. Special Resolution Regime if this Agreement were governed by the laws of the United States or a state of the United States.

For purposes of this Section 14:

15.Compliance with USA Patriot Act. In accordance with the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)), the Underwriters are required to obtain, verify and record information that identifies their respective clients, including the ZoomInfo Parties and the Selling Stockholders, which information may include the name and address of their respective clients, as well as other information that will allow the Underwriters to properly identify their respective clients.

16.Counterparts. This Agreement may be signed in two or more counterparts (which may include counterparts delivered by any standard form of telecommunication), each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument. The words “execution,” “signed,” “signature,” “delivery” and words of like import in or relating to this Agreement or any document to be signed in connection with this Agreement shall be deemed to include electronic signatures, deliveries or the keeping of records in electronic form, each of which shall be of the same legal effect, validity or enforceability as a manually executed signature, physical delivery thereof or the use of a paper-based recordkeeping system, as the case

may be, and the parties hereto consent to conduct the transactions contemplated hereunder by electronic means.

17.Applicable Law; Submission to Jurisdiction; Waiver of Jury Trial. (a) This Agreement, and any claim, controversy or dispute arising under or related to this Agreement, shall be governed by and construed in accordance with the internal laws of the State of New York.

(b) Each party hereby submits to the exclusive jurisdiction of the U.S. federal and New York state courts in the Borough of Manhattan in The City of New York in any suit or proceeding arising out of or relating to this Agreement or the transactions contemplated hereby.

Each party agrees that final judgment in any such suit, action or proceeding brought in such court shall be conclusive and binding upon each party and may be enforced in any court to the jurisdiction of which any party is subject by a suit upon such judgment.

(c) Each of the parties hereto hereby waives any right to trial by jury in any suit or proceeding arising out of or relating to this Agreement.

Ladies and Gentlemen:

The undersigned understands that J.P. Morgan Securities LLC and Morgan Stanley & Co. LLC (the “Representatives”) propose to enter into an underwriting agreement (the “Underwriting Agreement”) with ZoomInfo Technologies Inc., a Delaware corporation (the “Company”), ZoomInfo Intermediate Holdings LLC, a Delaware limited liability company (“ZoomInfo HoldCo”), and ZoomInfo Holdings LLC, a Delaware limited liability company (“ZoomInfo OpCo”), providing for the public offering (the “Public Offering”) by the several Underwriters, including the Representatives (the “Underwriters”), of 44,500,000 shares (the “Shares”) of the Class A common stock of the Company, par value $0.01 per share (the “Class A Common Stock”). The undersigned further understands that, prior to the consummation of the Public Offering, the Company will be authorized to issue, in addition to the Class A Common Stock, shares of its Class B common stock, par value $0.01 per share (the “Class B Common Stock”), and shares of its Class C common stock, par value $0.01 per share (the “Class C Common Stock” and, together with the Class A Common Stock and the Class B Common Stock, the “Common Stock”). Capitalized terms used herein and not otherwise defined shall have the meanings set forth in the Underwriting Agreement.

To induce the Underwriters that may participate in the Public Offering to continue their efforts in connection with the Public Offering, the undersigned hereby agrees that, without the prior written consent of the Representatives, it will not, and will not publicly disclose an intention to, during the period commencing on the date hereof and ending 180 days after the date of the final prospectus (the “Restricted Period”) relating to the Public

Offering (the “Prospectus”), (1) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend or otherwise transfer or dispose of, directly or indirectly, any shares of Class A Common Stock beneficially owned (as such term is used in Rule 13d-3 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) by the undersigned or any securities so owned convertible into or exercisable or exchangeable for Class A Common Stock, including, for the avoidance of doubt, any shares of Class B Common Stock, shares of Class C Common Stock, HoldCo Units, OpCo Units or Class P units of ZoomInfo OpCo (such shares of Class A Common Stock or other securities, collectively, the “Securities”) or (2) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of the Securities, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of Securities, in cash or otherwise. The undersigned acknowledges and agrees that the foregoing precludes the undersigned from engaging in any hedging or other transactions designed or intended, or which could reasonably be expected to lead to or result in, a sale or disposition of any Securities, even if any such sale or disposition transaction or transactions would be made or executed by or on behalf of someone other than the undersigned.

The foregoing restrictions shall not apply to:

(a)sales of Class A Common Stock by the undersigned to the Underwriters pursuant to the Underwriting Agreement;

(b)transactions relating to shares of Class A Common Stock acquired in open-market transactions after the completion of the Public Offering (provided that no filing under Section 16(a) of the Exchange Act shall be required or shall be voluntarily made during the Restricted Period in connection with subsequent sales of shares of Class A Common Stock acquired in such open-market transactions);

(c)transfers of the undersigned’s Securities (i) as a bona fide gift or for bona fide estate planning purposes, (ii) pursuant to a bona fide third-party tender offer, merger, consolidation or similar transaction made to all holders of Class A Common Stock involving a change of control of the Company (provided that if such transaction is not consummated, the undersigned’s Securities shall remain subject to the restrictions set forth herein) (for purposes of this clause (c), “change of control” means any bona fide third-party tender offer, merger, consolidation or other similar transaction the result of which is that any “person” (as defined in Section 13(d)(3) of the Exchange Act) or group of persons, other than the Company, becomes the beneficial owner (as defined in Rules 13d-3 and 13d-5 of the Exchange Act) of more than 50% of the total voting power of the voting stock of the Company) or (iii) if the undersigned is a corporation, limited liability company, partnership or other entity, as part of a disposition, transfer or distribution by the undersigned to any Subsidiary, affiliate

or investment fund or other entity controlled or managed by, or under common control or management with, the undersigned or to direct or indirect stockholders, members, current or former partners (general or limited), beneficiaries or other equityholders, or to the estates of any such stockholders, partners, beneficiaries or other equityholders of the undersigned or any of their respective affiliates (provided that (x) each donee, transferee or distributee shall sign and deliver a lock-up agreement substantially in the form of this letter agreement (this “Lock-Up Agreement”) and (y) no filing under Section 16(a) of the Exchange Act reporting a reduction in beneficial ownership of Securities shall be required or shall be voluntarily made during the Restricted Period);

(d)the establishment of a trading plan pursuant to Rule 10b5-1 under the Exchange Act for the transfer of shares of Class A Common Stock (provided that (i) such plan does not provide for the transfer of Class A Common Stock during the Restricted Period and (ii) to the extent a public announcement or filing under the Exchange Act, if any, is required of or voluntarily made during the Restricted Period by or on behalf of the undersigned or the Company regarding the establishment of such plan, such announcement or filing shall include a statement to the effect that no transfer of Class A Common Stock may be made under such plan during the Restricted Period);

(e)the exchange or redemption of any (x) shares of Class C Common Stock or (y) HoldCo Units, OpCo Units, vested Class P units in ZoomInfo OpCo, vested common units in HSKB, vested phantom units in HSKB or vested common units in HSKB II with a corresponding number of shares of Class B Common Stock (or securities convertible into or exercisable or exchangeable for Class C Common Stock, HoldCo Units or OpCo Units) for shares of Class A Common Stock (or securities convertible into or exercisable or exchangeable for Class A Common Stock) (provided that (i) such shares of Class A Common Stock and other securities remain subject to the terms of this Lock-Up Agreement and (ii) to the extent a public announcement or filing under the Exchange Act, if any, is required of or voluntarily made by or on behalf of the undersigned or the Company regarding the exchange or redemption, such announcement or filing shall include a statement to the effect that such exchange occurred pursuant to the Amended and Restated Charter, the ZoomInfo HoldCo LLC Agreement or the ZoomInfo OpCo LLC Agreement, in each case, as described in the Registration Statement, the Time of Sale Prospectus and the Prospectus that is in effect on or prior to the Closing Date, and no transfer of the shares of Class A Common Stock or other securities received upon exchange may be made during the Restricted Period other than pursuant to clause (c) above);

(f)the transfer, conversion, reclassification, redemption or exchange of any Securities pursuant to the Reorganization Transactions as described in the Prospectus (provided that any shares of Class A Common Stock or securities convertible into or exercisable or exchangeable for Class A Common Stock

received in the Reorganization Transactions remain subject to the terms of this Lock-Up Agreement);

(g)the transfer of shares of Class A Common Stock to the Company pursuant to the “cashless” exercise at expiration of options granted pursuant to any employee equity incentive plan of the Company outstanding on or prior to the Closing Date and referred to in the Registration Statement, the Time of Sale Prospectus and the Prospectus (each, an “Incentive Plan”) (provided that to the extent a public announcement or filing under the Exchange Act, if any, is required of or voluntarily made during the Restricted Period by or on behalf of the undersigned or the Company regarding the same, such announcement or filing shall include a statement to the effect that such transactions relate to such “cashless” exercise of options); or

(h)transfers of shares of Class A Common Stock to the Company in respect of tax withholding payments due upon the exercise at expiration of options or the vesting of equity-based awards pursuant to any Incentive Plan, in each case made on a “cashless” basis (provided that to the extent a public announcement or filing under the Exchange Act, if any, is required of or voluntarily made during the Restricted Period by or on behalf of the undersigned or the Company regarding the same, such announcement or filing shall include a statement to the effect that transactions relate to such tax withholding payments).

[In addition, the Representatives agree that should a discretionary release or waiver be granted to any officer or director of the Company, or any holder of 1% or more of the shares of Class A Common Stock immediately prior to the Public Offering (calculated on an as-converted, fully diluted basis and as of the close of business on the date of the Prospectus), other than the undersigned, then the undersigned will be released from the restrictions set forth in this Lock-Up Agreement subject to the same terms and conditions as the releasee and as to the same percentage of shares of Class A Common Stock (or securities convertible into or exercisable or exchangeable for Class A Common Stock) held by the undersigned as is held by the releasee (calculated on an as-converted basis, fully diluted basis as of the close of business on the date of the Prospectus). The Representatives shall provide at least three business days’ written notice to the Chief Financial Officer of the Company prior to the effective date of any such release or waiver under this Lock-Up Agreement (the effective date of such release or waiver, the “Release Date”), stating the percentage of shares of Class A Common Stock held by such person or entity to be released; provided that the failure to provide such notice shall not give rise to any claim or liability against the Representatives or the other Underwriters. The Company shall, within four business days thereafter, send written notice to the undersigned stating the same percentage of shares of Class A Common Stock (or securities convertible into or exercisable or exchangeable for Class A Common Stock) held by the undersigned as is held by the releasee on an as-converted basis shall be released from the restrictions set forth herein on the Release Date. The foregoing shall not apply to any release or waiver granted (a) solely to permit a transfer not for consideration,

(b) by the Representatives in their sole judgment that a record or beneficial owner of any securities should be granted an early release from a lock-up agreement due to circumstances of an emergency or hardship, (c) in connection with a registration statement filed with the Commission (provided that the undersigned has been given an opportunity to participate with other selling stockholders in such public offering on a pro rata basis, and in the event the underwriters of such offering make the determination to cut back the number of securities to be sold by stockholders in such offering, such cut back shall be applied to the undersigned pro rata with other holders proposing to sell securities in such offering) or (d) with respect to shares of Class A Common Stock (or securities convertible into or exercisable or exchangeable for Class A Common Stock) with a value of $1,000,000 or less, whether in one or multiple releases. For the avoidance of doubt, this paragraph shall not apply to any waiver or release of lock-up provisions with the Company or the Representatives to the extent that the transfer permitted by such waiver or release would be permitted under this Lock-Up Agreement.]¹

Notwithstanding anything to the contrary in this Lock-Up Agreement, the restrictions set forth in this Lock-Up Agreement shall not apply to the exercise of any right with respect to a registration of any Securities; provided that no transfer of the undersigned’s Securities proposed to be registered pursuant to the exercise of such rights under this paragraph shall occur, and no registration statement shall be publicly filed or announced, during the Restricted Period. In addition, the undersigned agrees and consents to the entry of stop transfer instructions with the Company’s transfer agent and registrar against the transfer of the undersigned’s Securities except in compliance with the foregoing restrictions.

If the undersigned is an officer or director of the Company, the undersigned further agrees that the foregoing restrictions shall be equally applicable to any issuer-directed Shares the undersigned may purchase in the Public Offering.

If the undersigned is an officer or director of a ZoomInfo Party, (i) the Representatives agree that, at least three business days before the effective date of any release or waiver of the foregoing restrictions in connection with a transfer of Securities, the Representatives will notify the Company of the impending release or waiver and (ii) the Company has agreed in the Underwriting Agreement to announce the impending release or waiver by (i) issuing a press release through a major news service at least two business days before the effective date of the release or waiver or (ii) any other method that satisfies the obligations described in FINRA Rule 5131(d)(2). Any release or waiver granted by the Representatives hereunder to any such officer or director shall only be effective two business days after the publication date of such press release. The provisions of this paragraph will not apply if (a) the release or waiver is effected solely to permit a transfer not for consideration and (b) the transferee has agreed in writing to be bound by the same terms described in this Lock-Up Agreement to the extent and for the duration that such terms remain in effect at the time of the transfer.

¹ NTD: To be included in Sponsor lock-ups.
