 Exhibit 10.6 

FORM OF DIRECTOR AND OFFICER INDEMNIFICATION AGREEMENT 

THIS INDEMNIFICATION AGREEMENT (the “Agreement”) is made and entered into as of
                    , 2021, between Definitive Healthcare Corp., a Delaware corporation (the “Company”), and
                     (“Indemnitee”). Capitalized terms not defined elsewhere in this Agreement are used as defined in
Section 13. 
 WHEREAS, the Board of Directors of the Company (the “Board”) has determined that it is reasonable,
prudent and necessary for the Company contractually to obligate itself to indemnify, hold harmless, exonerate and to advance expenses on behalf of, persons who serve the Company and its direct and indirect subsidiaries to the fullest extent
permitted by applicable law in order to, among other things, support the retention of highly competent persons who may be hesitant to serve in such roles without such protections; 

WHEREAS, this Agreement is a supplement to and in furtherance of the Company’s Amended and Restated Certificate of Incorporation (the
“Charter”) and the Amended and Restated Bylaws (the “Bylaws” and together with the Charter, the “Organizational Documents”), in each case, as may be amended from time to time, and any resolutions
adopted pursuant thereto, as well as any rights of Indemnitees under any directors’ and officers’ policies of liability insurance, and shall not be deemed a substitute therefor, nor to diminish or abrogate any rights of Indemnitee
thereunder; 
 WHEREAS, Indemnitee may not be willing to serve as an officer or director without adequate protection, and the Company
desires Indemnitee to serve in such capacity, and Indemnitee is willing to serve, continue to serve, and to take on additional service for or on behalf of the Company on the condition that Indemnitee be so indemnified; and 

WHEREAS, Indemnitee has certain rights to indemnification and/or insurance provided by affiliates of Advent International Corporation Spectrum
Equity Management, L.P. 22C Capital LLC (the “Sponsor”), which Indemnitee and Sponsor intend to be secondary to the primary obligation of the Company to indemnify Indemnitee as provided herein, with the Company’s
acknowledgement and agreement to the foregoing being a material condition to Indemnitee’s willingness to serve on the Board. 
 NOW,
THEREFORE, in consideration of the Indemnitee’s agreement to serve as a director or officer of the Company from and after the date hereof, and the premises and the covenants contained herein, the Company and Indemnitee do hereby covenant and
agree as follows: 
 1. Indemnity of Indemnitee. The Company hereby agrees to hold harmless and indemnify Indemnitee to the fullest
extent permitted by law, as such may be amended from time to time. In furtherance of the foregoing indemnification, and without limiting the generality thereof: 

 (a) Proceedings Other Than Proceedings by or in the Right of the Company. Indemnitee
shall be entitled to the rights of indemnification provided in this Section l(a) if, by reason of Indemnitee’s Corporate Status, Indemnitee is, or is threatened to be made, a party to or participant in any Proceeding other than a
Proceeding by or in the right of the Company. Pursuant to this Section 1(a), Indemnitee shall be indemnified against all Expenses, judgments, penalties, fines and amounts paid in settlement actually and reasonably incurred
by Indemnitee, or on Indemnitee’s behalf, in connection with such Proceeding or any claim, issue or matter therein, if Indemnitee acted in good faith and in a manner Indemnitee reasonably believed to be in or not opposed to the best interests
of the Company, and with respect to any criminal Proceeding, had no reasonable cause to believe Indemnitee’s conduct was unlawful. 

(b) Proceedings by or in the Right of the Company. Indemnitee shall be entitled to the rights of indemnification provided in this
Section 1(b) if, by reason of Indemnitee’s Corporate Status, Indemnitee is, or is threatened to be made, a party to or participant in any Proceeding brought by or in the right of the Company. Pursuant to this
Section 1(b), Indemnitee shall be indemnified against all Expenses actually and reasonably incurred by Indemnitee, or on Indemnitee’s behalf, in connection with such Proceeding if Indemnitee acted in good faith and in
a manner Indemnitee reasonably believed to be in or not opposed to the best interests of the Company; provided, however, if applicable law so provides, no indemnification against such Expenses shall be made in respect of any claim, issue or matter
in such Proceeding as to which Indemnitee shall have been adjudged to be liable to the Company unless and to the extent that the Court of Chancery of the State of Delaware shall determine that such indemnification may be made. 

(c) Indemnification for Expenses of a Party Who is Wholly or Partly Successful. Without limiting any other provision of this Agreement,
to the extent that Indemnitee is, by reason of Indemnitee’s Corporate Status, a party to and is successful, on the merits or otherwise, in any Proceeding, he shall be indemnified to the maximum extent permitted by law, as such may be amended
from time to time, against all Expenses actually and reasonably incurred by Indemnitee or on Indemnitee’s behalf in connection therewith. If Indemnitee is not wholly successful in such Proceeding but is successful, on the merits or otherwise,
as to one or more but less than all claims, issues or matters in such Proceeding, the Company shall indemnify Indemnitee against all Expenses actually and reasonably incurred by Indemnitee or on Indemnitee’s behalf in connection with each
successfully resolved claim, issue or matter. For purposes of this Section 1(c) and without limitation, the termination of any claim, issue or matter in such a Proceeding by dismissal, with or without prejudice, without
payment of any judgment, penalty or fine by Indemnitee, or on Indemnitee’s behalf, in connection with such claim issue or matter, shall be deemed to be a successful result as to such claim, issue or matter. 

(d) Partial Indemnification. If Indemnitee is entitled under any provision of this Agreement to indemnification by the Company for some
or a portion of Expenses, but not, however, for the total amount thereof, the Company shall nevertheless indemnify Indemnitee for the portion thereof to which Indemnitee is entitled. 

  
 2 

 2. Additional Indemnity. In addition to, and without regard to any limitations on,
the indemnification provided for in Section 1 of this Agreement, the Company shall and hereby does indemnify and hold harmless Indemnitee against all Expenses, judgments, penalties, fines and amounts paid in settlement
actually and reasonably incurred by Indemnitee or on Indemnitee’s behalf if, by reason of Indemnitee’s Corporate Status, Indemnitee is, or is threatened to be made, a party to or participant in any Proceeding (including a Proceeding by or
in the right of the Company), including, without limitation, all liability arising out of the negligence or active or passive wrongdoing of Indemnitee. The only limitation that shall exist upon the Company’s obligations pursuant to this
Agreement shall be that the Company shall not be obligated to make any payment to Indemnitee that is finally determined (under the procedures, and subject to the presumptions, set forth in Sections 6 and 7 hereof) to be unlawful. 

3. Contribution. 
 (a)
Whether or not the indemnification provided in Sections 1 and 2 hereof is available, in respect of any threatened, pending or completed action, suit or proceeding in which the Company is jointly liable with Indemnitee (or would be if
joined in such action, suit or proceeding), the Company shall pay, in the first instance, the entire amount of any judgment or settlement of such action, suit or proceeding without requiring Indemnitee to contribute to such payment and the Company
hereby waives and relinquishes any right of contribution it may have against Indemnitee. 
 (b) Without diminishing or impairing the
obligations of the Company set forth in the preceding subparagraph, if, for any reason, Indemnitee shall elect or be required to pay all or any portion of any judgment or settlement in any threatened, pending or completed action, suit or proceeding
in which the Company is jointly liable with Indemnitee (or would be if joined in such action, suit or proceeding), the Company shall contribute to the amount of Expenses, judgments, fines and amounts paid in settlement actually and reasonably
incurred and paid or payable by Indemnitee in proportion to the relative benefits received by the Company and all officers, directors or employees of the Company, other than Indemnitee, who are jointly liable with Indemnitee (or would be if joined
in such action, suit or proceeding), on the one hand, and Indemnitee, on the other hand, from the transaction from which such action, suit or proceeding arose; provided, however, that the proportion determined on the basis of relative benefit may,
to the extent necessary to conform to law, be further adjusted by reference to the relative fault of the Company and all officers, directors or employees of the Company other than Indemnitee who are jointly liable with Indemnitee (or would be if
joined in such action, suit or proceeding), on the one hand, and Indemnitee, on the other hand, in connection with the events that resulted in such expenses, judgments, fines or settlement amounts, as well as any other equitable considerations which
the Law may require to be considered. The relative fault of the Company and all officers, directors or employees of the Company, other than Indemnitee, who are jointly liable with Indemnitee (or would be if joined in such action, suit or
proceeding), on the one hand, and Indemnitee, on the other hand, shall be determined by reference to, among other things, the degree to which their actions were motivated by intent to gain personal profit or advantage, the degree to which their
liability is primary or secondary and the degree to which their conduct is active or passive. 
 (c) The Company hereby agrees to fully
indemnify and hold Indemnitee harmless from any claims of contribution that may be brought by officers, directors or employees of the Company, other than Indemnitee, who may be jointly liable with Indemnitee. 

  
 3 

 (d) To the fullest extent permissible under applicable law, if the indemnification provided
for in this Agreement is unavailable to Indemnitee for any reason whatsoever, the Company, in lieu of indemnifying Indemnitee, shall contribute to the amount incurred by Indemnitee, whether for judgments, fines, penalties, excise taxes, amounts paid
or to be paid in settlement and/or for Expenses, in connection with any claim relating to an indemnifiable event under this Agreement, in such proportion as is deemed fair and reasonable in light of all of the circumstances of such Proceeding in
order to reflect (i) the relative benefits received by the Company and Indemnitee as a result of the event(s) and/or transaction(s) giving cause to such Proceeding; and/or (ii) the relative fault of the Company (and its directors,
officers, employees and agents) and Indemnitee in connection with such event(s) and/or transaction(s). 
 4. Indemnification for Expenses
of a Witness. Notwithstanding any other provision of this Agreement, to the extent that Indemnitee is, by reason of Indemnitee’s Corporate Status, a witness, or is made (or asked to) respond to discovery requests, in any Proceeding to which
Indemnitee is not a party, he shall be indemnified against all Expenses actually and reasonably incurred by Indemnitee or on Indemnitee’s behalf in connection therewith. 

5. Advancement of Expenses. Notwithstanding any other provision of this Agreement, the Company shall advance all Expenses incurred by
or on behalf of Indemnitee in connection with any Proceeding by reason of Indemnitee’s Corporate Status within thirty (30) days after the receipt by the Company of a statement or statements from Indemnitee requesting such advance or
advances from time to time, whether prior to or after final disposition of such Proceeding. Such statement or statements shall reasonably evidence the Expenses incurred by Indemnitee and shall include or be preceded or accompanied by a written
undertaking by or on behalf of Indemnitee to repay any Expenses advanced if it shall ultimately be determined that Indemnitee is not entitled to be indemnified against such Expenses. Any advances and undertakings to repay pursuant to this
Section 5 shall be unsecured and interest free. 
 6. Procedures and Presumptions for Determination of
Entitlement to Indemnification. It is the intent of this Agreement to secure for Indemnitee rights of indemnity that are as favorable as may be permitted under the DGCL and public policy of the State of Delaware. Accordingly, the parties agree
that the following procedures and presumptions shall apply in the event of any question as to whether Indemnitee is entitled to indemnification under this Agreement: 

(a) To obtain indemnification under this Agreement, Indemnitee shall submit to the Corporate Secretary of the Company a written request,
including therein or therewith such documentation and information as is reasonably available to Indemnitee and is reasonably necessary to determine whether and to what extent Indemnitee is entitled to indemnification. The Corporate Secretary of the
Company shall, promptly upon receipt of such a request for indemnification, advise the Board in writing that Indemnitee has requested indemnification. Notwithstanding the foregoing, any failure of Indemnitee to provide such a request to the Company,
or to provide such a request in a timely fashion, shall not relieve the Company of any liability that it may have to Indemnitee unless, and to the extent that, such failure actually and materially prejudices the interests of the Company. 

  
 4 

 (b) Upon written request by Indemnitee for indemnification pursuant to the first sentence
of Section 6(a) hereof, a determination with respect to Indemnitee’s entitlement thereto shall be made in the specific case by one of the following four methods, which shall be at the election of the Board: (1) by
a majority vote of the Disinterested Directors, even though less than a quorum, (2) by a committee of Disinterested Directors designated by a majority vote of the Disinterested Directors, even though less than a quorum, (3) if there are no
Disinterested Directors, or if the Disinterested Directors so direct, by Independent Counsel in a written opinion to the Board, a copy of which shall be delivered to Indemnitee, or (4) if so directed by the Board, by the stockholders of the
Company; provided, however, that if a Change in Control has occurred, the determination with respect to Indemnitee’s entitlement to indemnification shall be made by Independent Counsel. 

(c) In the event the determination of entitlement to indemnification is to be made by Independent Counsel, the Independent Counsel shall be
selected as provided in this Section 6(c). If a Change in Control has not occurred, the Independent Counsel shall be selected by the Board (including a vote of a majority of the Disinterested Directors, if obtainable), and
the Company shall give written notice advising the Indemnitee of the identity of the Independent Counsel so selected. Indemnitee may, within 10 days after such written notice of selection shall have been given, deliver to the Company a written
objection to such selection; provided, however, that such objection may be asserted only on the ground that the Independent Counsel so selected does not meet the requirements of “Independent Counsel” as defined in
Section 13 of this Agreement, and the objection shall set forth with particularity the factual basis of such assertion. Absent a proper and timely objection, the person so selected shall act as Independent Counsel. If a
written objection is made, the Independent Counsel selected may not serve as Independent Counsel unless and until such objection is withdrawn or a court has determined that such objection is without merit. If a Change in Control has occurred, the
Independent Counsel shall be selected by the Indemnitee (unless the Indemnitee shall request that such selection be made by the Board, in which event the preceding sentence shall apply), and approved by the Board (which approval shall not be
unreasonably withheld). If (i) an Independent Counsel is to make the determination of entitlement pursuant to this Section 6, and (ii) within 20 days after submission by Indemnitee of a written request for
indemnification pursuant to Section 6(a) hereof, no Independent Counsel shall have been selected and not objected to, either the Company or Indemnitee may petition the Court of Chancery of the State of Delaware or other
court of competent jurisdiction for resolution of any objection which shall have been made by Indemnitee to the Company’s selection of Independent Counsel and/or for the appointment as Independent Counsel of a person selected by the court or by
such other person as the court shall designate, and the person with respect to whom all objections are so resolved or the person so appointed shall act as Independent Counsel under Section 6(b) hereof. The Company shall pay
any and all reasonable fees and expenses of Independent Counsel incurred by such Independent Counsel in connection with acting pursuant to Section 6(b) hereof, and the Company shall pay all reasonable fees and expenses
incident to the procedures of this Section 6(c), regardless of the manner in which such Independent Counsel was selected or appointed. 

  
 5 

 (d) In making a determination with respect to entitlement to indemnification
hereunder, the person or persons or entity making such determination shall presume that Indemnitee is entitled to indemnification under this Agreement. Anyone seeking to overcome this presumption shall have the burden of proof and the burden of
persuasion by clear and convincing evidence. Neither the failure of the Company (including by its directors or independent legal counsel) to have made a determination prior to the commencement of any action pursuant to this Agreement that
indemnification is proper in the circumstances because Indemnitee has met the applicable standard of conduct, nor an actual determination by the Company (including by its directors or independent legal counsel) that Indemnitee has not met such
applicable standard of conduct, shall be a defense to the action or create a presumption that Indemnitee has not met the applicable standard of conduct. 

(e) Indemnitee shall be deemed to have acted in good faith if Indemnitee’s action is based on the records or books of account of
the Enterprise, including financial statements, or on information supplied to Indemnitee by the officers of the Enterprise in the course of their duties, or on the advice of legal counsel for the Enterprise or on information or records given or
reports made to the Enterprise by an independent certified public accountant or by an appraiser or other expert selected with reasonable care by the Enterprise. The provisions of this Section 6(e) shall not be deemed to be
exclusive or to limit in any way the other circumstances in which the Indemnitee may be deemed to have met the applicable standard of conduct set forth in this Agreement. In addition, the knowledge and/or actions, or failure to act, of any director,
officer, agent or employee of the Enterprise shall not be imputed to Indemnitee for purposes of determining the right to indemnification under this Agreement. Whether or not the foregoing provisions of this Section 6(e) are
satisfied, it shall in any event be presumed that Indemnitee has at all times acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the Company. Anyone seeking to overcome this presumption shall
have the burden of proof and the burden of persuasion by clear and convincing evidence. 
 (f) If the person, persons or entity
empowered or selected under this Section 6 to determine whether Indemnitee is entitled to indemnification shall not have made a determination within sixty (60) days after receipt by the Company of the request therefor,
the requisite determination of entitlement to indemnification shall be deemed to have been made and Indemnitee shall be entitled to such indemnification absent (i) a misstatement by Indemnitee of a material fact, or an omission of a material
fact necessary to make Indemnitee’s statement not materially misleading, in connection with the request for indemnification, or (ii) a prohibition of such indemnification under applicable law; provided, however, that such 60-day period may be extended for a reasonable time, not to exceed an additional thirty (30) days, if the person, persons or entity making such determination with respect to entitlement to indemnification in
good faith requires such additional time to obtain or evaluate documentation and/or information relating thereto; and provided, further, that the foregoing provisions of this Section 6(f) shall not apply if the
determination of entitlement to indemnification is to be made by the stockholders pursuant to Section 6(b) of this Agreement and if (A) within fifteen (15) days after receipt by the Company of the request for such
determination, the Board or the Disinterested Directors, if appropriate, resolve to submit such determination to the stockholders for their consideration at an annual meeting thereof to be held within seventy-five (75) days after such receipt
and such determination is made thereat, or (B) a special meeting of stockholders is called within fifteen (15) days after such receipt for the purpose of making such determination, such meeting is held for such purpose within sixty
(60) days after having been so called and such determination is made thereat. 

  
 6 

 (g) Indemnitee shall cooperate with the person, persons or entity making such
determination with respect to Indemnitee’s entitlement to indemnification, including providing to such person, persons or entity upon reasonable advance request any documentation or information, which is not privileged or otherwise protected
from disclosure and which is reasonably available to Indemnitee and reasonably necessary to such determination. Any Independent Counsel, member of the Board or stockholder of the Company shall act reasonably and in good faith in making a
determination regarding Indemnitee’s entitlement to indemnification under this Agreement. Any costs or expenses (including attorneys’ fees and disbursements) incurred by Indemnitee in so cooperating with the person, persons or entity
making such determination shall be borne by the Company (irrespective of the determination as to Indemnitee’s entitlement to indemnification) and the Company hereby indemnifies and agrees to hold Indemnitee harmless therefrom. 

(h) The Company acknowledges that a settlement or other disposition short of final judgment may be successful if it permits a party to
avoid expense, delay, distraction, disruption and uncertainty. In the event that any action, claim or proceeding to which Indemnitee is a party is resolved in any manner other than by adverse judgment against Indemnitee (including, without
limitation, settlement of such action, claim or proceeding with or without payment of money or other consideration) it shall be presumed that Indemnitee has been successful on the merits or otherwise in such action, suit or proceeding. Anyone
seeking to overcome this presumption shall have the burden of proof and the burden of persuasion by clear and convincing evidence. 
 (i)
The termination of any Proceeding or of any claim, issue or matter therein, by judgment, order, settlement or conviction, or upon a plea of nolo contendere or its equivalent, shall not (except as otherwise expressly provided in this Agreement) of
itself adversely affect the right of Indemnitee to indemnification or create a presumption that Indemnitee did not act in good faith and in a manner which he reasonably believed to be in or not opposed to the best interests of the Company or, with
respect to any criminal Proceeding, that Indemnitee had reasonable cause to believe that Indemnitee’s conduct was unlawful. 
 7.
Remedies of Indemnitee. 
 (a) In the event that (i) a determination is made pursuant to Section 6 of
this Agreement that Indemnitee is not entitled to indemnification under this Agreement, (ii) advancement of Expenses is not timely made pursuant to Section 5 of this Agreement, (iii) no determination of
entitlement to indemnification is made pursuant to Section 6(b) of this Agreement within 90 days after receipt by the Company of the request for indemnification, (iv) payment of indemnification is not made pursuant to
this Agreement within ten (10) days after receipt by the Company of a written request therefor or (v) payment of indemnification is not made within ten (10) days after a determination has been made that Indemnitee is entitled to
indemnification or such determination is deemed to have been made pursuant to Section 6 of this Agreement, Indemnitee shall be entitled to an adjudication in an appropriate court of the State of Delaware, or in any other
court of competent jurisdiction, of Indemnitee’s entitlement to such indemnification, contribution or advancement of Expenses. Alternatively, Indemnitee, at such person’s option, may seek an award in arbitration to be conducted by a single
arbitrator pursuant to the Commercial Arbitration Rules of the American Arbitration Association. Except as set forth herein, the provisions of Delaware law (without regard to its conflict of law rules) shall apply to any such arbitration. The
Company shall not oppose Indemnitee’s right to seek any such adjudication or award in arbitration. 

  
 7 

 (b) In the event that a determination shall have been made pursuant to
Section 6(b) of this Agreement that Indemnitee is not entitled to indemnification, any judicial proceeding commenced pursuant to this Section 7 shall be conducted in all respects as a de novo
trial, or arbitration, on the merits, and Indemnitee shall not be prejudiced by reason of the adverse determination under Section 6(b). In any judicial proceeding or arbitration commenced pursuant to this
Section 7, Indemnitee shall be presumed to be entitled to indemnification under this Agreement and the Company shall have the burden of proving Indemnitee is not entitled to indemnification or advancement of Expenses, as
the case may be, and the Company may not refer to or introduce into evidence any determination pursuant to Section 6(b) of this Agreement adverse to Indemnitee for any purpose. If Indemnitee commences a judicial proceeding
or arbitration pursuant to this Section 7, Indemnitee shall not be required to reimburse the Company for any advances pursuant to Section 5 until a final determination is made with respect to
Indemnitee’s entitlement to indemnification (as to which all rights of appeal have been exhausted or lapsed). 
 (c) If a determination
shall have been made pursuant to Section 6(b) of this Agreement that Indemnitee is entitled to indemnification, the Company shall be bound by such determination in any judicial proceeding commenced pursuant to this
Section 7, absent (i) a misstatement by Indemnitee of a material fact, or an omission of a material fact necessary to make Indemnitee’s misstatement not materially misleading in connection with the application for
indemnification, or (ii) a prohibition of such indemnification under applicable law. 
 (d) In the event that Indemnitee, pursuant to
this Section 7, seeks a judicial adjudication of Indemnitee’s rights under, or to recover damages for breach of, this Agreement, or to recover under any directors’ and officers’ liability insurance policies
maintained by the Company, the Company shall pay on Indemnitee’s behalf, in advance, any and all expenses (of the types described in the definition of Expenses in Section 13 of this Agreement) actually and reasonably
incurred by Indemnitee in such judicial adjudication, regardless of whether Indemnitee ultimately is determined to be entitled to such indemnification, advancement of expenses or insurance recovery. 

(e) The Company shall be precluded from asserting in any judicial proceeding commenced pursuant to this Section 7
that the procedures and presumptions of this Agreement are not valid, binding and enforceable and shall stipulate in any such court that the Company is bound by all the provisions of this Agreement. It is the intent of the Company that, to the
fullest extent permitted by law, the Indemnitee not be required to incur legal fees or other Expenses associated with the interpretation, enforcement or defense of Indemnitee’s rights under this Agreement by litigation or otherwise because the
cost and expense thereof would substantially detract from the benefits intended to be extended to the Indemnitee hereunder. The Company shall indemnify Indemnitee against any and all Expenses and, if requested by Indemnitee, shall (within ten
(10) days after receipt by the Company of a written request therefore) advance, to the extent not prohibited by law, such expenses to Indemnitee, which are incurred by Indemnitee in connection with any action brought by Indemnitee for
indemnification or advance of Expenses from the Company under this Agreement or under any directors’ and officers’ liability insurance policies maintained by the Company, regardless of whether Indemnitee ultimately is determined to be
entitled to such indemnification, advancement of Expenses or insurance recovery, as the case may be. 

  
 8 

 (f) Notwithstanding anything in this Agreement to the contrary, no determination as to
entitlement to indemnification under this Agreement shall be required to be made prior to the final disposition of the Proceeding. 
 8. Non-Exclusivity; Survival of Rights; Insurance; Primacy of Indemnification; Subrogation. 
 (a) The
rights of indemnification and to receive advancement of expenses as provided by this Agreement shall not be deemed exclusive of any other rights to which Indemnitee may at any time be entitled under applicable law, the Organizational Documents, any
agreement, a vote of stockholders, a resolution of directors or otherwise, of the Company. No amendment, alteration or repeal of this Agreement or of any provision hereof shall limit or restrict any right of Indemnitee under this Agreement in
respect of any action taken or omitted by such Indemnitee in such person’s Corporate Status prior to such amendment, alteration or repeal. To the extent that a change in the DGCL, whether by statute or judicial decision, permits greater
indemnification than would be afforded currently under the Organizational Documents and this Agreement, it is the intent of the parties hereto that Indemnitee shall enjoy by this Agreement the greater benefits so afforded by such change. No right or
remedy herein conferred is intended to be exclusive of any other right or remedy, and every other right and remedy shall be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity
or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other right or remedy. 

(b) The Company shall obtain and maintain in effect during the entire period for which the Company is obligated to indemnify Indemnitee under
this Agreement, one or more policies of insurance with one or more reputable insurance companies to provide the directors and officers of the Company with coverage for losses from wrongful acts and omissions and to ensure the Company’s
performance of its indemnification obligations under this Agreement. Indemnitee shall be covered by such policy or policies in accordance with its or their terms to the maximum extent of the coverage available for any such director or officer under
such policy or policies. In all such insurance policies, Indemnitee shall be named as an insured in such a manner as to provide Indemnitee with the same rights and benefits as are accorded to the most favorably insured of the Company’s
directors and officers. At the time of the receipt of a notice of a claim pursuant to the terms hereof, the Company shall give prompt notice of the commencement of such proceeding to the insurers in accordance with the procedures set forth in the
respective policies. The Company shall thereafter take all necessary or desirable action to cause such insurers to pay, on behalf of Indemnitee, all amounts payable as a result of such proceeding in accordance with the terms of such policies. 

  
 9 

 (c) The Company hereby acknowledges that Indemnitee has certain rights to indemnification,
advancement of expenses and/or insurance provided by Sponsor and certain affiliates that, directly or indirectly, (i) are controlled by, (ii) control or (iii) are under common control with, Sponsor (collectively, the “Fund
Indemnitors”). The Company hereby agrees (i) that it is the indemnitor of first resort (i.e., its obligations to Indemnitee are primary and any obligation of the Fund Indemnitors to advance expenses or to provide indemnification for
the same expenses or liabilities incurred by Indemnitee are secondary), (ii) that it shall be required to advance the full amount of expenses incurred by Indemnitee and shall be liable for the full amount of all Expenses, judgments, penalties, fines
and amounts paid in settlement to the extent legally permitted and as required by the terms of this Agreement and the Certificate of Incorporation or By-laws of the Company (or any other agreement between the
Company and Indemnitee), without regard to any rights Indemnitee may have against the Fund Indemnitors, and, (iii) that it irrevocably waives, relinquishes and releases the Fund Indemnitors from any and all claims against the Fund Indemnitors for
contribution, subrogation or any other recovery of any kind in respect thereof. The Company further agrees that no advancement or payment by the Fund Indemnitors on behalf of Indemnitee with respect to any claim for which Indemnitee has sought
indemnification from the Company shall affect the foregoing and the Fund Indemnitors shall have a right of contribution and/or be subrogated to the extent of such advancement or payment to all of the rights of recovery of Indemnitee against the
Company. The Company and Indemnitee agree that the Fund Indemnitors are express third party beneficiaries of the terms of this Section 8(d). 

(d) [Except as provided in Section 8(c) above, i][I]n the event of any payment under this Agreement, the Company
shall be subrogated to the extent of such payment to all of the rights of recovery of Indemnitee [(other than against the Fund Indemnitors)], who shall execute all papers required and take all action necessary to secure such rights, including
execution of such documents as are necessary to enable the Company to bring suit to enforce such rights. 
 (e) [Except as provided in
Section 8(c) above, t][T]he Company shall not be liable under this Agreement to make any payment of amounts otherwise indemnifiable hereunder if and to the extent that Indemnitee has otherwise actually received such payment
under any insurance policy, contract, agreement or otherwise. 
 (f) [Except as provided in Section 8(c) above,
t][T]he Company’s obligation to indemnify or advance Expenses hereunder to Indemnitee who is or was serving at the request of the Company as a director, officer, employee or agent of any other corporation, partnership, joint venture, trust,
employee benefit plan or other Enterprise shall be reduced by any amount Indemnitee has actually received as indemnification or advancement of expenses from such other corporation, partnership, joint venture, trust, employee benefit plan or other
enterprise. 
 9. Exception to Right of Indemnification. Notwithstanding any provision in this Agreement, the Company shall not be
obligated under this Agreement to make any indemnity in connection with any claim made against Indemnitee: 

  
 10 

 (a) for which payment has actually been made to or on behalf of Indemnitee under any
insurance policy or other indemnity provision, except with respect to any excess beyond the amount paid under any insurance policy or other indemnity provision[; provided, that the foregoing shall not affect the rights of Indemnitee or the
Fund Indemnitors set forth in Section 8(c) above]; or 
 (b) for an accounting of profits made from the purchase
and sale (or sale and purchase) by Indemnitee of securities of the Company within the meaning of Section 16(b) of the Exchange Act or similar provisions of state statutory law or common law; or 

(c) for reimbursement to the Company of any bonus or other incentive-based or equity-based compensation or of any profits realized by
Indemnitee from the sale of securities of the Company in each case as required under the Exchange Act; or 
 (d) in connection with any
Proceeding (or any part of any Proceeding) initiated by Indemnitee, including any Proceeding (or any part of any Proceeding) initiated by Indemnitee against the Company or its directors, officers, employees or other indemnitees, unless (i) the
Company has joined in or the Board authorized the Proceeding (or any part of any Proceeding) prior to its initiation, (ii) the Company provides the indemnification, in its sole discretion, pursuant to the powers vested in the Company under
applicable law, or (iii) the Proceeding is one to enforce Indemnitee’s rights under this Agreement. 
 10. Non-Disclosure of Payments. Except as expressly required by the securities laws of the United States of America, neither party shall disclose any payments under this Agreement unless prior approval of the other
party is obtained. If any payment information must be disclosed, the Company shall afford the Indemnitee an opportunity to review all such disclosures and, if requested, to explain in such statement any mitigating circumstances regarding the events
to be reported. 
 11. Duration of Agreement. All agreements and obligations of the Company contained herein shall continue upon the
later of (a) ten (10) years after the date that Indemnitee shall have ceased to serve as a director of the Company or a director, officer, trustee, partner, managing member, fiduciary, employee or agent of any other corporation, partnership,
joint venture, trust, employee benefit plan or other Enterprise which Indemnitee served at the request of the Company; or (b) one (1) year after the final termination of any Proceeding (including any rights of appeal thereto) in respect of
which Indemnitee is granted rights of indemnification or advancement of Expenses hereunder and of any Proceeding commenced by Indemnitee pursuant to Section 7 of this Agreement relating thereto (including any rights of
appeal of any Section 7 Proceeding). This Agreement shall be binding upon and inure to the benefit of and be enforceable by the parties hereto and their respective successors (including any direct or indirect successor by
purchase, merger, consolidation or otherwise to all or substantially all of the business or assets of the Company), assigns, spouses, heirs, executors and personal and legal representatives. 

12. Security. To the extent requested by Indemnitee and approved by the Board, the Company may at any time and from time to time
provide security to Indemnitee for the Company’s obligations hereunder through an irrevocable bank line of credit, funded trust or other collateral. Any such security, once provided to Indemnitee, may not be revoked or released without the
prior written consent of Indemnitee.

inaction on Indemnitee’s part while acting pursuant to Indemnitee’s Corporate Status, or by reason of the fact that Indemnitee is or was serving at the request of the Company as a director, officer, employee, agent or fiduciary of another
corporation, partnership, joint venture, trust or other Enterprise; in each case whether or not Indemnitee is acting or serving in any such capacity at the time any liability or expense is incurred for which indemnification can be provided under

 14. Severability. If any provision or provisions of this Agreement shall be held to be invalid, illegal or unenforceable for any
reason whatsoever: (a) the validity, legality, and enforceability of the remaining provisions of this Agreement (including, without limitation, each portion of any Section, paragraph or sentence of this Agreement containing any such provision
held to be invalid, illegal or unenforceable, that is not itself invalid, illegal or unenforceable) shall not in any way be affected or impaired thereby and shall remain enforceable to the fullest extent permitted by law; (b) such provision or
provisions shall be deemed reformed to the fullest extent necessary to conform to applicable law and to give the maximum effect to the intent of the parties hereto; and (c) to the fullest extent possible, the provisions of this Agreement
(including, without limitation, each portion of any Section, paragraph or sentence of this Agreement containing any such provision held to be invalid, illegal or unenforceable, that is not itself invalid, illegal or unenforceable) shall be construed
so as to give effect to the intent manifested thereby. Without limiting the generality of the foregoing, this Agreement is intended to confer upon Indemnitee indemnification rights to the fullest extent permitted by applicable laws. 

15. Enforcement and Binding Effect. 

(a) The Company expressly confirms and agrees that it has entered into this Agreement and assumed the obligations imposed on it hereby in
order to induce Indemnitee to serve as a director or officer of the Company, and the Company acknowledges that Indemnitee is relying upon this Agreement in serving in such capacity. 

  
 14 

 (b) Without limiting any of the rights of Indemnitee under the Charter or By-laws of the Company as they may be amended from time to time, this Agreement constitutes the entire agreement between the parties hereto with respect to the subject matter hereof and supersedes all prior
agreements and understandings, oral, written and implied, between the parties hereto with respect to the subject matter hereof. 
 (c) The
indemnification and advancement of expenses provided by, or granted pursuant to this Agreement shall be binding upon and be enforceable by the parties hereto and their respective successors and assigns (including any direct or indirect successor by
purchase, merger, consolidation or otherwise to all or substantially all of the business or assets of the Company), shall continue as to an Indemnitee who has ceased to be a director, officer, employee or agent of the Company or of any other
Enterprise at the Company’s request, and shall inure to the benefit of Indemnitee and such person’s spouse, assigns, heirs, devisees, executors and administrators and other legal representatives. 

(d) The Company shall require and cause any successor (whether direct or indirect by purchase, merger, consolidation or otherwise) to all,
substantially all or a substantial part, of the business and/or assets of the Company to expressly to assume and agree to perform this Agreement in the same manner and to the same extent that the Company would be required to perform if no such
succession had taken place. 
 (e) The Company and Indemnitee agree herein that a monetary remedy for breach of this Agreement, at some
later date, may be inadequate, impracticable and difficult of proof, and further agree that such breach may cause Indemnitee irreparable harm. Accordingly, the parties hereto agree that Indemnitee may enforce this Agreement by seeking injunctive
relief and/or specific performance hereof, without any necessity of showing actual damage or irreparable harm and that by seeking injunctive relief and/or specific performance, Indemnitee shall not be precluded from seeking or obtaining any other
relief to which he may be entitled. The Company and Indemnitee further agree that Indemnitee shall be entitled to such specific performance and injunctive relief, including temporary restraining orders, preliminary injunctions and permanent
injunctions, without the necessity of posting bonds or other undertaking in connection therewith. The Company acknowledges that in the absence of a waiver, a bond or undertaking may be required of Indemnitee by the Court, and the Company hereby
waives any such requirement of such a bond or undertaking. 
 16. Modification and Waiver. No supplement, modification, termination
or amendment of this Agreement shall be binding unless executed in writing by both of the parties hereto. No waiver of any of the provisions of this Agreement shall be deemed or shall constitute a waiver of any other provisions hereof (whether or
not similar) nor shall such waiver constitute a continuing waiver. 

  
 15 

 17. Notice by Indemnitee. Indemnitee agrees promptly to notify the Company in writing
upon being served with or otherwise receiving any summons, citation, subpoena, complaint, indictment, information or other document relating to any Proceeding or matter which may be subject to indemnification covered hereunder. The failure to so
notify the Company shall not relieve the Company of any obligation which it may have to Indemnitee under this Agreement or otherwise. 
 18.

 Exhibit 10.7 

THE DEFINITIVE HEALTHCARE CORP. 

2021 EMPLOYEE STOCK PURCHASE PLAN

1.    General; Purpose. 

(a)    The Plan provides a means by which Eligible Employees and/or Eligible Service Providers of either the Company or a
Designated Company may be given an opportunity to purchase Common Stock. The Plan permits the Company to grant a series of Purchase Rights to Eligible Employees and/or Eligible Service Providers. 

(b)    The Company, by means of the Plan, seeks to retain and assist its Related Corporations or Affiliates in retaining
the services of such Eligible Employees and Eligible Service Providers, to secure and retain the services of new Eligible Employees and Eligible Service Providers and to provide incentives for such persons to exert maximum efforts for the success of
the Company and its Related Corporations and Affiliates. 
 (c)    The Plan includes two components: a 423 Component and
a Non-423 Component. The Company intends (but makes no undertaking or representation to maintain) the 423 Component to qualify as an Employee Stock Purchase Plan. The provisions of the 423 Component,
accordingly, will be construed in a manner that is consistent with the requirements of Section 423 of the Code, including without limitation, to extend and limit Plan participation in a uniform and
non-discriminating basis. In addition, this Plan authorizes grants of Purchase Rights under the Non-423 Component that do not meet the requirements of an Employee Stock
Purchase Plan. Except as otherwise provided in the Plan or determined by the Board, the Non-423 Component will operate and be administered in the same manner as the 423 Component. In addition, the Company may
make separate Offerings which vary in terms (provided that such terms are not inconsistent with the provisions of the Plan and, with respect to the 423 Component, the requirements of an Employee Stock Purchase Plan), and the Company will designate
which Designated Company is participating in each separate Offering and if any Eligible Service Providers will be eligible to participate in a separate Offering. Eligible Employees will be able to participate in the 423 Component or Non-423 Component of the Plan. Eligible Service Providers will only be able to participate in the Non-423 Component of the Plan. 

2.    Administration. 

(a)    The Board will administer the Plan unless and until the Board delegates administration of the Plan to a Committee or
Committees, as provided in Section 2(c). 
 (b)    The Board will have the power, subject to, and within the
limitations of, the express provisions of the Plan: 
 (i)    To determine how and when Purchase Rights will be granted
and the provisions of each Offering (which need not be identical). 

 (ii)    To designate from time to time which Related Corporations will
be eligible to participate in the Plan as Designated 423 Corporations or as Designated Non-423 Corporations, which Affiliates will be eligible to participate in the Plan as Designated Non-423 Corporations, and which Designated Companies will participate in each separate Offering (to the extent that the Company makes separate Offerings). 

(iii)    To designate from time to time which persons will be Eligible Service Providers and which Eligible Service
Providers will participate in each separate Offering (to the extent that the Company makes separate Offerings). 

(iv)    To construe and interpret the Plan and Purchase Rights, and to establish, amend and revoke rules and regulations
for its administration. The Board, in the exercise of this power, may correct any defect, omission or inconsistency in the Plan, in a manner and to the extent it deems necessary or expedient to make the Plan fully effective. 

(v)    To settle all controversies regarding the Plan and Purchase Rights granted under the Plan. 

(vi)    To suspend or terminate the Plan at any time as provided in Section 12. 

(vii)    To amend the Plan at any time as provided in Section 12. 

(viii)    Generally, to exercise such powers and to perform such acts as it deems necessary or expedient to promote the
best interests of the Company, its Related Corporations, and Affiliates and to carry out the intent that the 423 Component be treated as an Employee Stock Purchase Plan. 

(ix)    To adopt such rules, procedures and sub-plans relating to the operation
and administration of the Plan as are necessary or appropriate under applicable local laws, regulations and procedures to permit or facilitate participation in the Plan by Employees or Eligible Service Providers who are non-U.S. nationals or employed or providing services or located or otherwise subject to the laws of a jurisdiction outside the United States. Without limiting the generality of, but consistent with, the
foregoing, the Board specifically is authorized to adopt rules, procedures, and sub-plans, which, for purposes of the Non-423 Component, may be beyond the scope of
Section 423 of the Code, regarding, without limitation, eligibility to participate in the Plan, handling and making of Contributions, establishment of bank or trust accounts to hold Contributions, payment of interest, conversion of local
currency, obligations to pay payroll tax, determination of beneficiary designation requirements, withholding procedures and handling of stock issuances, any of which may vary according to applicable requirements. 

(c)    The Board may delegate some or all of the administration of the Plan to a Committee or Committees. If
administration is delegated to a Committee, the Committee will have, in connection with the administration of the Plan, the powers theretofore possessed by the Board that have been delegated to the Committee, including the power to delegate to a
subcommittee any of the administrative powers the Committee is authorized to exercise (and references in this Plan to the Board will thereafter be to the Committee or subcommittee), subject, however, to such resolutions, not inconsistent with the
provisions of the Plan, as may be adopted from time to time by the Board. The Board may retain the authority to concurrently administer the Plan with the Committee and may, at 

  
 -2- 

 
any time, revest in the Board some or all of the powers previously delegated. Whether or not the Board has delegated administration of the Plan to a Committee, the Board will have the final power
to determine all questions of policy and expediency that may arise in the administration of the Plan. 
 (d)    All
determinations, interpretations and constructions made by the Board in good faith will not be subject to review by any person and will be final, binding and conclusive on all persons. 

3.    Stock Subject to the Plan. 

(a)    Subject to the provisions of Section 11(a) relating to Capitalization Adjustments and Section 3(b), the
maximum number of shares of Common Stock that may be issued under the Plan will not exceed [    ] shares of Common Stock. 

(b)    On the first day of each Fiscal Year of the Company during the term of the Plan, commencing on January 1, 2023
and ending on (and including) January 1, 2032 the aggregate number of shares of Common Stock that may be issued under the Plan shall automatically increase by a number equal to the least of (i) 1.0% of the total number of shares of Common Stock
actually issued and outstanding on the last day of the preceding fiscal year, (ii) a number of shares of Common Stock determined by the Board; and (iii) [    ] shares of Common Stock. For the avoidance of doubt, up to the
maximum number of shares of Common Stock reserved under this Section 3(a) may be used to satisfy purchases of Common Stock under the 423 Component and any remaining portion of such maximum number of shares may be used to satisfy purchases of
Common Stock under the Non-423 Component. 
 (c)    If any Purchase Right
granted under the Plan terminates without having been exercised in full, the shares of Common Stock not purchased under such Purchase Right will again become available for issuance under the Plan. 

(d)    The stock purchasable under the Plan will be shares of authorized but unissued or reacquired shares of Common
Stock, including shares repurchased by the Company on the open market. 
 (e)    Any
sub-plan adopted pursuant to Section 2(b)(ix) of the Plan shall be subject to the limits on shares of Common Stock under the Plan (inclusive of any adjustments), and shall be subject to the same share
recycling provisions as the Plan (relating to purchase rights granted that terminate without having been exercised in full). 

4.    Grant of Purchase Rights; Offering. 

(a)    The Board may from time to time grant or provide for the grant of Purchase Rights to Eligible Employees and/or
Eligible Service Providers under an Offering (consisting of one 

  
 -3- 

 
or more Purchase Periods) on an Offering Date or Offering Dates selected by the Board. Each Offering will be in such form and will contain such terms and conditions as the Board will deem
appropriate, and, with respect to the 423 Component, will comply with the requirement of Section 423(b)(5) of the Code that all Employees granted Purchase Rights will have the same rights and privileges. The terms and conditions of an
Offering will be incorporated by reference into the Plan and treated as part of the Plan. The provisions of separate Offerings need not be identical, but each Offering will include (through incorporation of the provisions of this Plan by reference
in the Offering Document or otherwise) the period during which the Offering will be effective, which period will not exceed 27 months beginning with the Offering Date, and the substance of the provisions contained in Sections 5 through 8,
inclusive. 
 (b)    If a Participant has more than one Purchase Right outstanding under the Plan, unless he or she
otherwise indicates in forms delivered to the Company: (i) each form will apply to all of his or her Purchase Rights under the Plan, and (ii) a Purchase Right with a lower exercise price (or an earlier-granted Purchase Right, if different
Purchase Rights have identical exercise prices) will be exercised to the fullest possible extent before a Purchase Right with a higher exercise price (or a later-granted Purchase Right if different Purchase Rights have identical exercise prices)
will be exercised. 
 (c)    The Board will have the discretion to structure an Offering so that if the Fair Market
Value of a share of Common Stock on the first Trading Day of a new Purchase Period within that Offering is less than or equal to the Fair Market Value of a share of Common Stock on the Offering Date for that Offering, then (i) that Offering
will terminate immediately as of that first Trading Day, and (ii) the Participants in such terminated Offering will be automatically enrolled in a new Offering beginning on the first Trading Day of such new Offering Period and Purchase Period.

 5.    Eligibility. 

(a)    Purchase Rights may be granted only to Employees of the Company or, as the Board may designate in accordance with
Section 2(b), to Employees of a Related Corporation or, solely with respect to the Non-423 Component, Employees of an Affiliate or Eligible Service Providers. 

(b)    The Board may provide that Employees will not be eligible to be granted Purchase Rights under the Plan if, on the
Offering Date, the Employee (i) has not completed at least two years of service since the Employee’s last hire date (or such lesser period of time as may be determined by the Board in its discretion), (ii) customarily works not
more than 20 hours per week (or such lesser period of time as may be determined by the Board in its discretion), (iii) customarily works not more than five months per calendar year (or such lesser period of time as may be determined by the
Board in its discretion), (iv) is an Officer, (v) is a highly compensated employee within the meaning of Section 423(b)(4)(D) of the Code, or (vi) has not satisfied such other criteria as the Board may determine consistent with
Section 423 of the Code. Unless otherwise determined by the Board for any Offering Period, an Employee will not be eligible to be granted Purchase Rights unless, on the Offering Date, the Employee customarily works more than 20 hours per week
and more than five months per calendar year, and has been employed by the Company, a Related Corporation, or an Affiliate, as the case may be, for at least three continuous months preceding such Offering Date. 

  
 -4- 

 (c)    No Employee will be eligible for the grant of any Purchase Rights
if, immediately after any such Purchase Rights are granted, such Employee owns stock possessing five percent or more of the total combined voting power or value of all classes of stock of the Company or of any Related Corporation. For purposes of
this Section 5(c), the rules of Section 424(d) of the Code will apply in determining the stock ownership of any Employee, and common stock which such Employee may purchase under all outstanding Purchase Rights and options will be treated
as stock owned by such Employee. 
 (d)    As specified by Section 423(b)(8) of the Code, an Eligible Employee may
be granted Purchase Rights only if such Purchase Rights, together with any other rights granted under all Employee Stock Purchase Plans of the Company and any Related Corporations, do not permit such Eligible Employee’s rights to purchase stock
of the Company or any Related Corporation to accrue at a rate which, when aggregated, exceeds U.S. $25,000 of Fair Market Value of such stock (determined at the time such rights are granted, and which, with respect to the Plan, will be determined as
of their respective Offering Dates) for each calendar year in which such rights are outstanding at any time. 

(e)    An Eligible Service Provider will not be eligible to be granted Purchase Rights unless the Eligible Service
Provider is providing bonafide services to the Company or a Designated Company on the applicable Offering Date. 

(f)    Notwithstanding anything set forth herein except for Section 5(e) above, the Board may establish additional
eligibility requirements, or fewer eligibility requirements, for Employees and/or Eligible Service Providers with respect to Offerings made under the Non-423 Component even if such requirements are not
consistent with Section 423 of the Code. 
 6.    Purchase Rights; Purchase Price. 

(a)    On each Offering Date, each Eligible Employee or Eligible Service Provider, pursuant to an Offering made under the
Plan, will be granted a Purchase Right to purchase up to that number of shares of Common Stock (rounded down to the nearest whole share) purchasable either with a percentage or with a maximum dollar amount, as designated by the Board; provided
however, that in the case of Eligible Employees, such percentage or maximum dollar amount will in either case not exceed 15% of such Employee’s earnings (as defined by the Board in each Offering) during the period that begins on the Offering
Date (or such later date as the Board determines for a particular Offering) and ends on the date stated in the Offering, which date will be no later than the end of the Offering, unless otherwise provided for in an Offering. 

(b)    The Board will establish one or more Purchase Dates during an Offering on which Purchase Rights granted for that
Offering will be exercised and shares of Common Stock will be purchased in accordance with such Offering. 
 (c)    In
connection with each Offering made under the Plan, the Board may specify (i) a maximum number of shares of Common Stock that may be purchased by any Participant on any Purchase Date during such Offering, (ii) a maximum aggregate number of
shares of Common Stock that may be purchased by all Participants pursuant to such Offering, and (iii) a maximum aggregate number of shares of Common Stock that may be purchased by all Participants on any Purchase Date under the Offering. If the
aggregate purchase of shares of Common Stock issuable on exercise of 

  
 -5- 

 
Purchase Rights granted under the Offering would exceed any such maximum aggregate number, then, in the absence of any Board action otherwise, a pro rata (based on each Participant’s
accumulated Contributions) allocation of the shares of Common Stock (rounded down to the nearest whole share) available will be made in as nearly a uniform manner as will be practicable and equitable. 

(d)    The purchase price of shares of Common Stock acquired pursuant to Purchase Rights will be not less than the lesser
of: 
 (i)    an amount equal to 85% of the Fair Market Value of the shares of Common Stock on the Offering Date; or

 (ii)    an amount equal to 85% of the Fair Market Value of the shares of Common Stock on the applicable Purchase
Date. 
 7.    Participation; Withdrawal; Termination. 

(a)    An Eligible Employee may elect to authorize payroll deductions as the means of making Contributions by completing
and delivering to the Company, within the time specified by the Company, an enrollment form provided by the Company or any third party designated by the Company (each, a “Company Designee”). The enrollment form will specify the
amount of Contributions not to exceed the maximum amount specified by the Board. Each Participant’s Contributions will be credited to a bookkeeping account for such Participant under the Plan and will be deposited with the general funds of the
Company except where applicable laws or regulations require that Contributions be deposited with a Company Designee or otherwise be segregated. 

(b)    If permitted in the Offering, a Participant may begin Contributions with the first payroll or payment date
occurring on or after the Offering Date (or, in the case of a payroll date or payment date that occurs after the end of the prior Offering but before the Offering Date of the next new Offering, Contributions from such payroll or payment will be
included in the new Offering) or on such other date as set forth in the Offering. If permitted in the Offering, a Participant may thereafter reduce (including to zero) or increase his or her Contributions. If required under applicable laws or
regulations or if specifically provided in the Offering, in addition to or instead of making Contributions by payroll deductions, a Participant may make Contributions through a payment by cash, check, or wire transfer prior to a Purchase Date, in a
manner directed by the Company or a Company Designee. 
 (c)    During an Offering, a Participant may cease making
Contributions and withdraw from the Offering by delivering to the Company or a Company Designee a withdrawal form provided by the Company. The Company may impose a deadline before a Purchase Date for withdrawing. On such withdrawal, such
Participant’s Purchase Right in that Offering will immediately terminate and the Company will distribute as soon as practicable to such Participant all of his or her accumulated but unused Contributions without interest and such
Participant’s Purchase Right in that Offering will then terminate. A Participant’s withdrawal from that Offering will have no effect on his or her eligibility to participate in any other Offerings under the Plan, but such Participant will
be required to deliver a new enrollment form to participate in subsequent Offerings. 
 (d)    Purchase Rights granted
pursuant to any Offering under the Plan will terminate immediately if the Participant either (i) is no longer an Eligible Employee or Eligible Service Provider for any reason or for no reason, or (ii) is otherwise no longer eligible to
participate. The Company 

  
 -6- 

 
shall have the exclusive discretion to determine when Participant is no longer actively providing services and the date of the termination of employment or service for purposes of the Plan. As
soon as practicable, the Company will distribute to such individual all of his or her accumulated but unused Contributions without interest. 

(e)    During a Participant’s lifetime, Purchase Rights will be exercisable only by such Participant. Purchase Rights
are not transferable by a Participant, except by will, by the laws of descent and distribution, or, if permitted by the Company, by a beneficiary designation as described in Section 10. 

(f)    Unless otherwise specified in the Offering or required by applicable laws, the Company will have no obligation to
pay interest on Contributions. 
 8.    Exercise of Purchase Rights. 

(a)    On each Purchase Date, each Participant’s accumulated Contributions will be applied to the purchase of shares
of Common Stock (rounded down to the nearest whole share), up to the maximum number of shares of Common Stock permitted by the Plan and the applicable Offering, at the purchase price specified in the Offering. No fractional shares will be issued
unless specifically provided for in the Offering. 
 (b)    Unless otherwise provided in the Offering, if any amount of
accumulated Contributions remains in a Participant’s account after the purchase of shares of Common Stock on the final Purchase Date in an Offering, then such remaining amount will roll over to the next Offering. 

(c)    No Purchase Rights may be exercised to any extent unless the shares of Common Stock to be issued on such exercise
under the Plan are covered by an effective registration statement pursuant to the Securities Act and the Plan is in material compliance with all applicable U.S. federal and state, non-U.S. and other
securities, exchange control and other laws applicable to the Plan. If on a Purchase Date the shares of Common Stock are not so registered or the Plan is not in such compliance, no Purchase Rights will be exercised on such Purchase Date, and the
Purchase Date will be delayed until the shares of Common Stock are subject to such an effective registration statement and the Plan is in material compliance, except that the Purchase Date will in no event be more than three (3) months from the
original Purchase Date. If, on the Purchase Date, as delayed to the maximum extent permissible, the shares of Common Stock are not registered and the Plan is not in material compliance with all applicable laws or regulations, as determined by the
Company in its sole discretion, no Purchase Rights will be exercised and all accumulated but unused Contributions will be distributed as soon as practicable to the Participants without interest. 

9.    Covenants of the Company. The Company will seek to obtain from each U.S. federal or state, non-U.S. or other regulatory commission or agency having jurisdiction over the Plan such authority as may be required to grant Purchase Rights and issue and sell shares of Common Stock thereunder unless the Company
determines, in its sole discretion, that doing so would cause the Company to incur costs that are unreasonable. If, after commercially reasonable efforts, the Company is unable to obtain the authority that counsel for the Company deems necessary for
the grant of Purchase Rights or the lawful issuance and sale of Common Stock under the Plan, and at a commercially reasonable cost, the Company will be relieved from any liability for failure to grant Purchase Rights or to issue and sell Common
Stock on exercise of such Purchase Rights. 

  
 -7- 

 10.    Designation of Beneficiary. 

(a)    The Company may, but is not obligated to, permit a Participant to submit a form designating any beneficiary or
beneficiaries who will receive any shares of Common Stock or Contributions from the Participant’s account under the Plan if the Participant dies before such shares of Common Stock or Contributions are delivered to the Participant. The Company
may, but is not obligated to, permit the Participant to change such designation of beneficiary. Each such designation shall revoke all prior designations by the same Participant and will be effective only when filed by the Participant in writing (on
a form approved by the Company or as approved by the Company for use by a Company Designee) with the Company during the Participant’s lifetime. 

(b)    In the absence of a valid designation as provided in Section 10(a) above, if no validly designated beneficiary
survives the Participant or if each surviving validly designated beneficiary is legally impaired or prohibited from receiving any shares of Common Stock or Contributions, the Participant’s beneficiary shall be the legatee or legatees designated
under the Participant’s last will or by such Participant’s executors, personal representatives or distributees of such shares of Common Stock or Contributions in accordance with the Participant’s will or the laws of descent and
distribution. If no executor or administrator has been appointed (to the knowledge of the Company), the Company, in its sole discretion, may deliver such shares of Common Stock and Contributions, without interest, to the Participant’s spouse,
dependents or relatives, or if no spouse, dependent or relative is known to the Company, then to such other person as the Company may designate. Any transfer permitted under this Section 10 shall be for no consideration. 

11.    Capitalization Adjustments; Dissolution or Liquidation; Change in Control. 

(a)    In the event of a Capitalization Adjustment, the Board will appropriately and proportionately adjust: (i) the
class(es) and maximum number of securities subject to the Plan pursuant to Section 3(a), (ii) the class(es) and maximum number of securities by which the share reserve is to increase automatically each year pursuant to Section 3(a), (iii)
the class(es) and number of securities subject to, and the purchase price applicable to outstanding Offerings and Purchase Rights, and (iv) the class(es) and number of securities that are the subject of the purchase limits under each ongoing
Offering. The Board will make these adjustments, and its determination will be final, binding, and conclusive. 

(b)    In the event of a dissolution or liquidation of the Company, the Board will shorten any Offering then in progress
by setting a New Purchase Date prior to the consummation of such proposed dissolution or liquidation. The Board will notify each Participant in writing, prior to the New Purchase Date that the Purchase Date for the Participant’s Purchase Rights
has been changed to the New Purchase Date and that such Purchase Rights will be automatically exercised on the New Purchase Date, unless prior to such date the Participant has withdrawn from the Offering as provided in Section 7. 

  
 -8- 

 (c)    In the event of a Change in Control, then: (i) any surviving
corporation or acquiring corporation (or the surviving or acquiring corporation’s parent company) may assume or continue outstanding Purchase Rights or may substitute similar rights (including a right to acquire the same consideration paid to
the stockholders in the Change in Control) for outstanding Purchase Rights, or (ii) if any surviving or acquiring corporation (or its parent company) does not assume or continue such Purchase Rights or does not substitute similar rights for
such Purchase Rights, then the Participants’ accumulated Contributions will be used to purchase shares of Common Stock (rounded down to the nearest whole share) prior to the Change in Control under the outstanding Purchase Rights (with such
actual date to be determined by the Board in its sole discretion), and the Purchase Rights will terminate immediately after such purchase. The Board will notify each Participant in writing, prior to the New Purchase Date that the Purchase Date for
the Participant’s Purchase Rights has been changed to the New Purchase Date and that such Purchase Rights will be automatically exercised on the New Purchase Date, unless prior to such date the Participant has withdrawn from the Offering as
provided in Section 7. 
 12.    Amendment, Termination or Suspension of the Plan. 

(a)    The Board may amend the Plan at any time in any respect the Board deems necessary or advisable. However, except as
provided in Section 11(a) relating to Capitalization Adjustments, stockholder approval will be required for any amendment of the Plan for which stockholder approval is required by applicable laws, regulations or listing requirements, including
any amendment that either (i) increases the number of shares of Common Stock available for issuance under the Plan, (ii) expands the class of individuals eligible to become Participants and receive Purchase Rights, (iii) materially
increases the benefits accruing to Participants under the Plan or reduces the price at which shares of Common Stock may be purchased under the Plan, (iv) extends the term of the Plan, or (v) expands the types of awards available for
issuance under the Plan, but in each of (i) through (v) above only to the extent stockholder approval is required by applicable laws, regulations, or listing requirements. 

(b)    The Board may suspend or terminate the Plan at any time. No Purchase Rights may be granted under the Plan while the
Plan is suspended or after it is terminated. 
 (c)    Any benefits, privileges, entitlements, and obligations under any
outstanding Purchase Rights granted before an amendment, suspension, or termination of the Plan will not be materially impaired by any such amendment, suspension, or termination except (i) with the consent of the person to whom such Purchase
Rights were granted, (ii) as necessary to comply with any laws, listing requirements, or governmental regulations (including, without limitation, the provisions of Section 423 of the Code and the regulations and other interpretive guidance
issued thereunder relating to Employee Stock Purchase Plans) including without limitation any such regulations or other guidance that may be issued or amended after the date the Plan is adopted by the Board, or (iii) as necessary to obtain or
maintain any special tax, listing, or regulatory treatment. To be clear, the Board may amend outstanding Purchase Rights without a Participant’s consent if such amendment is necessary to ensure that the Purchase Right or the 423 Component
complies with the requirements of Section 423 of the Code. 
 13.    Sections 409A and 457A
of the Code; Tax Qualification. 
 (a)    Purchase Rights granted under the 423 Component are intended to be exempt
from the application of Section 409A of the Code. Purchase Rights granted under the Non-423 

  
 -9- 

 
Component to U.S. taxpayers are intended to be exempt from the application of Section 409A of the Code under the short-term deferral exception and any ambiguities will be construed and
interpreted in accordance with such intent. Subject to Section 13(b) below, Purchase Rights granted to U.S. taxpayers under the Non-423 Component will be subject to such terms and conditions that will
permit such Purchase Rights to satisfy the requirements of the short-term deferral exception or other exemption available under Section 409A of the Code, including the requirement that the shares subject to a Purchase Right be delivered within
the short-term deferral period. Subject to Section 13(b) below, in the case of a Participant who would otherwise be subject to Section 409A of the Code, to the extent the Board determines that a Purchase Right or the exercise, payment,
settlement, or deferral thereof is subject to Section 409A of the Code, the Purchase Right will be granted, exercised, paid, settled, or deferred in a manner that will comply with Section 409A of the Code, including U.S. Department of
Treasury regulations and other interpretive guidance issued thereunder, including, without limitation, any such regulations or other guidance that may be issued after the adoption of the Plan. Notwithstanding the foregoing, in no event whatsoever
shall the Company be liable for any additional tax, interest or penalties that may be imposed on a Participant by Section 409A of the Code or any damages for failing to comply with Section 409A of the Code. 

(b)    Purchase Rights are intended to be exempt from the application of Section 457A of the Code. In the event that
the Committee determines that Purchase Rights may be subject to Section 457A of the Code, the Committee may, in its sole discretion and without a Participant’s prior consent, amend the Plan and/or adopt policies and procedures, or take any
other actions (including amendments, policies, procedures and actions with retroactive effect) as are necessary or appropriate to (i) exempt the Plan and/or any Purchase Right from the application of Section 457A, (ii) preserve the
intended tax treatment of any such Purchase Right, or (iii) comply with the requirements of Section 457A, including without limitation any such regulations, guidance, compliance programs and other interpretative authority that may be
issued after the date of the grant. To the extent that a Purchase Right constitutes deferred compensation subject to Section 457A, such Purchase Right will be subject to taxation in accordance with Section 457A. Notwithstanding the
foregoing, in no event whatsoever shall the Company be liable for any additional tax, interest or penalties that may be imposed on a Participant by Section 457A of the Code or any damages for failing to comply with Section 457A of the
Code. 
 (c)    Although the Company may endeavor to (i) qualify a Purchase Right for special tax treatment under
the laws of the United States or jurisdictions outside of the United States, or (ii) avoid adverse tax treatment (e.g., under Section 409A or Section 457A of the Code), the Company makes no representation to that effect and
expressly disavows any covenant to maintain special or to avoid unfavorable tax treatment, notwithstanding anything to the contrary in this Plan, including Section 13(a) above. The Company will be unconstrained in its corporate activities
without regard to the potential negative tax impact on Participants under the Plan. 
 14.    Effective Date of
Plan. The Plan will become effective on the Effective Date. No Purchase Rights will be exercised unless and until the Plan has been approved by the stockholders of the Company, which approval must be within 12 months before or after the date the
Plan is adopted (or, if required under Section 12(a) above, amended) by the Board. 

  
 -10- 

 15.    Miscellaneous Provisions. 

(a)    Proceeds from the sale of shares of Common Stock pursuant to Purchase Rights will constitute general funds of the
Company. 
 (b)    A Participant will not be deemed to be the holder of, or to have any of the rights of a holder with
respect to, shares of Common Stock subject to Purchase Rights unless and until the Participant’s shares of Common Stock acquired on exercise of Purchase Rights are recorded in the books of the Company (or its transfer agent). 

(c)    The Plan and Offerings do not constitute an employment or service contract. Nothing in the Plan or in the Offerings
will in any way alter the at-will nature of a Participant’s employment, if applicable, or be deemed to create in any way whatsoever any obligation on the part of any Participant to continue his or her
employment or service relationship with the Company, a Related Corporation, or an Affiliate, or on the part of the Company, a Related Corporation, or an Affiliate to continue the employment or service of a Participant. 

(d)    The provisions of the Plan will be governed by the laws of the State of Delaware. 

(e)    If any particular provision of the Plan is found to be invalid or otherwise unenforceable, such provision will not
affect the other provisions of the Plan, but the Plan will be construed in all respects as if such invalid provision were omitted. 

(f)    If any provision of the Plan does not comply with applicable laws or regulations, such provision will be construed
in such a manner as to comply with applicable laws or regulations.

after such amalgamation, merger, consolidation, or scheme of arrangement; provided, however, that an amalgamation, merger, consolidation, or scheme of arrangement effected to implement a recapitalization of the Company (or similar transaction) in

the date as of which Fair Market Value is to be determined, or if shares of Common Stock are not publicly traded on such date, as of the most recent date on which shares of Common Stock were publicly traded. Notwithstanding the foregoing, if the
