ADTHEORENT HOLDING COMPANY, LLC

 

PARTICIPANT INTEREST AGREEMENT

 

This PARTICIPANT INTEREST
AGREEMENT (this “Agreement”) is made as of October 1, 2017, between AdTheorent Holding Company, LLC, a Delaware
limited liability company (the “Company”), and the individual set forth on the signature page hereto (“Optionee”).

 

Optionee is executing this
Agreement in connection with Optionee’s receipt of Options (as defined below) pursuant to the AdTheorent Holding Company, LLC 2017
Interest Option Plan (the “Plan”), and employment with the Company and/or its Subsidiaries. Certain capitalized terms
used herein are defined in Section 8 hereof. All capitalized terms not otherwise defined herein shall have the meanings set
forth in the Plan, and to the extent not defined in the Plan, then as defined in the Operating Agreement.

 

This Agreement provides for
the issuance to Optionee of options (each an “Option” and collectively, the “Options”) to purchase
that number of Non-Voting Class C Interests set forth on the signature page hereto (collectively, the “Participant
Interests”) subject to the terms and conditions set forth herein and in the Operating Agreement.

 

The parties hereto agree as
follows:

 

		1.	Grant of Options.

 

		(a)	Issuance. Upon the date hereof (the “Grant Date”), the Company shall grant to Optionee,
and Optionee shall accept, Options to purchase from the Company the Participant Interests. For purposes of this Agreement, all of the
Options set forth as such on the signature page hereto shall be designated “Time Options.” For each Participant
Interest purchased in accordance with the terms of this Agreement, the Plan and the Operating Agreement, Optionee shall pay to the Company
the price set forth on the signature page hereto (the “Exercise Price”).

 

		(b)	Representations and Warranties of Optionee. In connection with the issuance of the Options hereunder,
Optionee represents and warrants to the Company that:

 

		(i)	the Participant Interests to be acquired by Optionee pursuant to this Agreement shall be acquired for
Optionee’s own account and not with a view to, or intention of, distribution thereof in violation of the Securities Act, or any
applicable state securities laws, and the Participant Interests shall not be disposed of in contravention of the Securities Act or any
applicable state securities laws;

 

		(ii)	Optionee is an executive, a managerial or a key employee of the Company and/or its Subsidiaries;

 

		(iii)	Optionee understands that the Participant Interests have not been registered under the Securities Act
and, therefore, cannot be sold unless subsequently registered under the Securities Act or an exemption from such registration is available;

 

     

     

    

 

		(iv)	Optionee has had an opportunity to ask questions and receive answers concerning the terms and conditions
of the issuance of the Options and the Participant Interests and has had full access to such other information concerning the Company
as Optionee has requested; Optionee has reviewed, or has had an opportunity to review, the Operating Agreement, a copy of which is attached
hereto as Exhibit A;

 

		(v)	this Agreement constitutes the legal, valid and binding obligation of Optionee, enforceable in accordance
with its terms, and the execution, delivery and performance of this Agreement by Optionee do not and shall not conflict with, violate
or cause a breach of any agreement, contract or instrument to which Optionee is a party or any judgment, order or decree to which Optionee
is subject; and

 

		(vi)	Optionee is a resident of the state set forth on the signature page hereto.

 

		(c)	As an inducement to the Company to grant the Options to Optionee and as a condition thereto, Optionee
acknowledges and agrees that:

 

		(i)	none of the grant of the Options, the issuance of the Participant Interests to Optionee or any provision
contained herein shall entitle Optionee to remain in the employment of any AdTheorent Company or affect the right of the AdTheorent Companies
to terminate Optionee’s employment at any time, for any reason or no reason, with or without Cause; and

 

		(ii)	except as otherwise provided by the Plan or the Operating Agreement or non-waiveable provisions of applicable
law, the Company shall have no duty or obligation to disclose to Optionee, and Optionee shall have no right to be advised of, any material
information regarding the Company or any of its Subsidiaries at any time.

 

		(d)	The parties hereto acknowledge and agree that the Options granted and any Participant Interests issued
pursuant to this Agreement are being offered to Optionee in consideration of the services rendered to the Company and its Subsidiaries
as additional compensation under a “written compensation contract” as contemplated by Rule 701 of the Securities Act.

 

		2.	Restrictions on Transfer and Repurchase Rights. The Options and the Participant Interests shall
be subject to the restrictions on Transfer set forth in the Operating Agreement and the repurchase rights set forth in Section 6.

 

		3.	Term of Options; Forfeiture of Options.

 

		(a)	The term of the Options (the “Option Period”) shall be a period beginning on the date
hereof and ending at the earliest of (i) the date that is ten (10) years from the date hereof, (ii) immediately following
the consummation of a Sale of the Company, (iii) the thirtieth (30th) day following the termination of Optionee’s employment
with the AdTheorent Companies without Cause, (iv) 60 days following a termination of employment due to death or Disability and (v) immediately
following a termination of employment for any other reason (including resignation by the Optionee). Except as set forth in Section 3(b) below,
the expiration of the Option Period shall result in the termination and cancellation of the Options and the Options shall not be exercisable
at any time after the expiration of the Option Period and the Optionee (and his or her successors) shall have no rights whatsoever with
respect to any Options from and after such termination and cancellation.

 

     

     

    

 

		(b)	Upon the termination of Optionee’s employment with the AdTheorent Companies (i) in connection
with the death or Disability of Optionee or the termination of Optionee’s employment with the AdTheorent Companies by the AdTheorent
Companies without Cause, (A) the Unvested Options shall automatically be forfeited and cancelled for no consideration without any
further action and (B) any Participant Interests purchased through the exercise of any Options shall be subject to the repurchase
rights set forth in Section 6; or (ii) for any other reason, (A) all of the Options (both Vested Options and Unvested
Options) shall automatically be forfeited and cancelled for no consideration without any further action and (B) any Participant Interests
previously purchased through the exercise of any Options shall be subject to the repurchase rights set forth in Section 6.

 

		4.	Vesting.

 

		(a)	Time Option Vesting. The Time Options shall become vested and exercisable pursuant to the table
set forth below, provided that Optionee is, and has been continuously, employed by an AdTheorent Company from the date hereof through
such date:

 

	Date	 	Percentage of Time Options

 which become Vested	 
	The later of (i) December 31, 2017; or (ii) the date which is the 12-month anniversary of the Optionee’s employment start date (the “Initial Vesting Date”)	 	 	25	%
	The later of (i) December 31, 2018; or (ii) the date which is the 12-month anniversary of the Initial Vesting Date	 	 	25	%
	The later of (i) December 31, 2019; or (ii) the date which is the 24-month anniversary of the Initial Vesting Date	 	 	25	%
	The later of (i) December 31, 2020; or (ii) the date which is the 36-month anniversary of the Initial Vesting Date	 	 	25	%

 

     

     

    

 

provided
however, that, if Optionee is, and has been continuously, employed by an AdTheorent Company from the date hereof through the
consummation of a Sale of the Company, then upon such Sale of the Company, all of the remaining Time Options shall become vested and exercisable;
provided further that in the event the Time Options become vested and exercisable upon a Sale of the Company and the purchase price
paid by the buyer in connection with such Sale of the Company which is allocated to each Participant Interest is less than the Exercise
Price of any portion of the Participant Interests issued hereunder, such Participant Interests shall be deemed forfeited and canceled
and shall have no further force or effect upon consummation of such Sale of the Company. Notwithstanding the foregoing, in all cases vesting
of the Time Options shall cease upon the termination of Optionee’s employment with the AdTheorent Companies.

 

		(b)	“Vested Options” shall mean Time Options that have become vested and exercisable pursuant
to the terms of this Agreement. “Unvested Options” shall mean Time Options that have not become Vested Options pursuant
to the terms of this Agreement.

 

		5.	Exercise.

 

		(a)	Vested Options may be exercised in whole or in part upon payment of an amount (the “Option Price”)
equal to the product of (i) the Exercise Price multiplied by (ii) the number of Participant Interests to be acquired. Payment
shall be made in cash (including check); provided, however, that solely to the extent an Option is being exercised in contemplation
of and contingent upon a Sale of the Company, where the Participant Interests acquired by Optionee are to be sold or transferred in connection
with such Sale of the Company, then, at Optionee’s option, Optionee may exercise the Option by surrender of the Option to the Company
in exchange for that number of Participant Interests issuable upon such exercise less a number of Participant Interests having an aggregate
Fair Market Value equal to the aggregate Exercise Price payable for the portion of the Option being exercised (in each case, subject to
adjustment and withholding for required taxes and withholdings).

 

		(b)	Optionee acknowledges and agrees that, in connection with the exercise of Vested Options pursuant to the
terms of his Agreement, Optionee shall be bound by the terms of, and subject to the conditions set forth in, the Operating Agreement,
including, without limitation, the drag-along and related obligations set forth therein upon a Sale of the Company.

 

		(c)	To the extent permitted to do so hereunder, Vested Options may be exercised by delivering (i) written
notice to the Company (to the attention of the Company’s Secretary) and Optionee’s written acknowledgment that Optionee has
read and been afforded an opportunity to ask questions of management of the Company regarding all financial and other information provided
to Optionee regarding the Company, together with payment of the Exercise Price in accordance with the provisions of Section 5(a) above,
(ii) an executed Joinder Agreement to the Operating Agreement in the form of Exhibit B hereto and (ii) an executed
spousal consent (if applicable) in the form of Exhibit C hereto and (iii) all other agreements and documents as the Company
may reasonably request. As a condition to any exercise of any Vested Option, Optionee shall permit the Company to deliver to Optionee
all financial and other information regarding the Company it believes necessary to enable Optionee to make an informed investment decision,
and Optionee shall make all customary investment representations which the Company requires.

 

     

     

    

 

		(d)	Section 83(b). Within 30 days after the date of any exercise of Options, Optionee shall
make an effective election with the Internal Revenue Service under Section 83(b) of the Internal Revenue Code and the regulations
promulgated thereunder in the form of Exhibit D attached hereto. Option shall also include a copy of such election in its
current year’s tax return.

 

		6.	Repurchase Option.

 

		(a)	Upon the death, Disability or termination or expiration for any other reason of Optionee’s employment
or independent contractor relationship with, or service to, the AdTheorent Companies (each, a “Termination Event”),
the Company shall have the right, but not the obligation, to purchase all or any portion of the Participant Interests held by any member
of Optionee’s Member Group (all such Participant Interests, collectively, the “Repurchased Interests”; and such
members of Optionee’s Member Group, collectively, the “Repurchase Sellers”) at a price per Participation Interest
equal to the Repurchase Price for each such Participation Interest by delivering a written notice of such election to the Repurchase Sellers
within 120 days after the occurrence of such Termination Event (the date of such written notice, the “Repurchase Notice Date”).
The “Repurchase Price” for the Repurchased Interests shall mean (i) their Fair Market Value if such termination
occurred as a result of the death or Disability of Optionee or the termination of Optionee’s employment or independent contractor
relationship with, or service to, the AdTheorent Companies by a AdTheorent Company without Cause, or (B) $1.00 (one dollar) in the
aggregate for all Repurchased Interests if the termination or expiration of Optionee’s employment or independent contractor relationship
with, or service to, the AdTheorent Companies occurred for any other reason.

 

		(b)	The Company may assign its rights under this Section 6 to one or more Voting Members. If more
than one eligible Voting Member elects to purchase the Repurchased Interests, they may do so pro rata based on the number of Voting Class A
Interests held by each of them or in such other proportions as they may agree. No member of a Member Group of Optionee shall be eligible
to purchase any Repurchased Interests under this Section 6.

 

		(c)	If the Company elects to purchase any Repurchased Interests pursuant to this Section 6, to
the extent permitted by the AdTheorent Companies’ credit facilities in effect from time to time and applicable law and to the extent
the Company has cash available, the purchase price shall be payable in cash with the balance of the purchase price to be paid in the form
of an unsecured fully subordinated promissory note issued by the Company (i) bearing interest at a fixed rate equal to the “prime
rate” as published in The Wall Street Journal on the Repurchase Notice Date and (ii) (A) maturing in whole or in part,
as applicable, on the earliest date on which the foregoing conditions are satisfied as to all or any portion of the note balance and (B) to
the extent not earlier repaid, maturing in whole upon the bankruptcy or insolvency of the Company. The applicable Repurchase Seller and
its successors and assigns will, from time to time, execute such reasonable subordination agreements as are requested by any AdTheorent
Company’s current and future lenders. If a Voting Member elects to purchase any Repurchased Interests pursuant to this Section 6,
the purchase price with respect to such Repurchased Interests shall be payable in cash or such other form of consideration agreed to by
the parties.

 

     

     

    

 

		(d)	The Company and/or eligible Voting Members, as applicable, will designate in writing to the Repurchase
Sellers, the time, date and place of any purchase under this Section 6, provided that such purchase shall occur within thirty
(30) days of the date of the election by the Company and/or such Voting Members, as applicable, to consummate such transaction. At the
closing of a purchase pursuant to this Section 6, each Repurchase Seller shall make such representations and warranties relating
to the sale, transfer and ownership of such Repurchased Interests and execute and deliver such other documents and instruments, as the
Company and/or Voting Members, as applicable, may reasonably request, including, but not limited to, a representation and warranty that
each such Repurchase Seller is conveying to the Company and/or Voting Members, as applicable, all of the Repurchased Interests free and
clear of all liens, claims and encumbrances, except for those liens, claims and encumbrances set forth in the Operating Agreement. If
the Company and/or Voting Members, as applicable, shall be ready, willing and able, at the time and place and in the amount and form provided
in this Section 6 to deliver the consideration for any Repurchased Interests to be purchased in accordance with this Section 6
and a Repurchase Seller shall not comply with its obligations hereunder, then from and after such time, such Repurchase Seller shall no
longer have any rights as an Interest Holder or otherwise with respect to such Repurchased Interests (other than the right to receive
payment of the Repurchase Price in accordance with this Section 6), and such Repurchased Interest shall be deemed purchased
in accordance with the applicable provisions hereof and the Company and/or Voting Members, as applicable, shall be deemed the owner and
holder of such Repurchased Interest.

 

     

     

    

 

		7.	Confidentiality; Restrictive Covenants; Other Agreements.

 

		(a)	Confidential Information.

 

		(i)	Optionee acknowledges that all Confidential Information (as defined below) obtained by him while employed
by the Company or its Subsidiaries or Affiliates concerning the business or affairs of the Company or any Subsidiary or Affiliate are
the property of the Company or such Subsidiary or Affiliate and constitute a protectable business interest of the Company and its Subsidiaries
or Affiliates. Optionee acknowledges that the Confidential Information has been generated at great effort and expense by the Company,
its Subsidiaries and Affiliates and their predecessors, and has been reasonably maintained in a confidential manner by such persons and
entities. Optionee does not claim any rights to or lien on any Confidential Information. Optionee will immediately notify the Company
of any unauthorized possession, use, disclosure, copying, removal or destruction, or attempt thereof, of any Confidential Information
by anyone of which the Optionee becomes aware and of all details thereof. Optionee shall take all reasonably appropriate steps to safeguard
(including by abiding by all Company and Subsidiary policies with respect to) Confidential Information and to protect it against disclosure,
misuse, espionage, loss and theft. Therefore, Optionee agrees that he shall not disclose, furnish, make available or utilize, directly
or indirectly, any Confidential Information without the prior written consent of the Operating Board, unless and to the extent that the
Confidential Information becomes generally known to and available for use by the public other than as a result of Optionee’s acts
or omissions. Optionee shall deliver to the Company at the termination or expiration of his employment with the Company, or its Subsidiaries
or Affiliates, or at any other time the Company may request, all memoranda, notes, plans, records, reports, computer tapes, computers,
printouts and software and other documents and data (and copies thereof) embodying or relating to the Confidential Information, Inventions
(as defined below) or the business of the Company, or any of its Subsidiaries, or Affiliates which he may then possess or have under his
control.

 

		(ii)	As used in this Agreement, the term “Confidential Information” means any and all confidential,
proprietary or trade secret information, whether disclosed, directly or indirectly, verbally, in writing or by any other means in tangible
or intangible form, including that which is conceived or developed by Optionee, applicable to or in any way related to: (i) the present
or future business and assets of the Company and its Subsidiaries and Affiliates; (ii) the research and development of the Company
and its Subsidiaries and Affiliates; or (iii) the business of any client, customer, supplier, vendor or other business relation of
the Company and its Subsidiaries and Affiliates. Such Confidential Information includes the following property or information of the Company
and its Subsidiaries and Affiliates, by way of example and without limitation, trade secrets, processes, formulas, data, program documentation,
customer lists, designs, drawings, algorithms, source code, object code, know-how, improvements, inventions, licenses, techniques, all
plans or strategies for marketing, development and pricing, business plans, financial statements, profit margins and all information concerning
existing or potential clients, suppliers, employees and vendors. Confidential Information of the Company and its Subsidiaries and Affiliates
also means all similar information disclosed to the Company and its Subsidiaries and Affiliates by third parties which is subject to confidentiality
obligations. Notwithstanding the foregoing, the provisions of this Section 7(a) shall not apply in the following circumstances:
(1) when disclosure of Confidential Information is required by law or by any court, arbitrator, mediator or administrative or legislative
body; provided, that prior to such disclosure Optionee shall provide to the Company and its Subsidiaries and Affiliates prompt
notice of such required disclosure to enable such entities to seek a protective order or other relief, and reasonably cooperate with the
such entities in connection with seeking any such order or other relief; or (2) with respect to Confidential Information that becomes
generally known to the public other than due to (A) Optionee’s violation of this Agreement or any other obligation or duty
to the Company, its Subsidiaries or Affiliates or (B) a disclosure by a third party who owes the Company, its Subsidiaries or its
Affiliates an obligation of confidence in relation to such Confidential Information.

 

     

     

    

 

		(iii)	During the term of Optionee’s employment with the Company, its Subsidiaries or Affiliates, including
the period following the expiration of the Employment Period, Optionee shall be prohibited from using or disclosing any confidential information
or trade secrets that Optionee may have learned through any prior employment. If at any time during his employment with the Company or
any Subsidiary or Affiliate, Optionee believes he is being asked to engage in work that will, or will be likely to, jeopardize any confidentiality
or other obligations Optionee may have to former employers or other parties, Optionee shall immediately advise the Operating Board and
provide it with documents pertaining thereto. Optionee represents and warrants that he is not aware of any confidential information or
trade secrets of any prior employers that he will need or rely on in carrying out his duties and responsibilities hereunder.

 

		(iv)	Notwithstanding the foregoing, pursuant to 18 U.S.C. § 1833(b)(1): “An
individual shall not be held criminally or civilly liable under any federal or state trade secret law for the disclosure of a trade secret
that (A) is made (i) in confidence to a federal, state, or local government official, either directly or indirectly, or to an
attorney; and (ii) solely for the purpose of reporting or investigating a suspected violation of law; or (B) is made in a complaint
or other document filed in a lawsuit or other proceeding, if such filing is made under seal.” Any employee, contractor or consultant
who is found to have wrongfully misappropriated trade secrets may be liable for, among other things, exemplary damages and attorneys’
fees.

 

     

     

    

 

		(b)	Inventions, Patents and Intellectual Property.

 

		(i)	Optionee covenants and agrees that all Inventions (as defined below) shall be the sole and exclusive property
of the Company and its Subsidiaries.

 

		(ii)	As used in this Agreement, the term “Inventions” means any and all inventions, developments,
discoveries, improvements, works of authorship, concepts or ideas, or expressions thereof, whether or not subject to patents, copyright,
trademark, trade secret protection or other intellectual property right protection (in the United States or elsewhere), and whether or
not reduced to practice, conceived or developed by Optionee while employed with the Company or within one year following termination of
such employment, which relate to or result from the actual or anticipated business, work, research or investigation of the Company and
its Subsidiaries or which are suggested by or result from any task assigned to or performed by Optionee for the Company and its Subsidiaries
or any of its Affiliates.

 

		(iii)	Optionee acknowledges that all original works of authorship which are made by him (solely or jointly)
are works made for hire under the United States Copyright Act (17 U.S.C., et seq.).

 

		(iv)	Optionee agrees to promptly disclose to the Company all Inventions and all work product relating thereto.
This disclosure will include complete and accurate copies of all source code, object code or machine readable copies, documentation, work
notes, flow charts, diagrams, test data, reports, samples and other tangible evidence or results (collectively, “Tangible Embodiments”)
of such Inventions and related work product. All Tangible Embodiments of any Invention or work product related thereto will be deemed
to have been assigned to the Company (or any applicable Subsidiary) as a result of the act of expressing any Invention therein.

 

		(v)	Optionee hereby assigns to the Company (together with the right to prosecute or sue for infringements
or other violations of the same) the entire worldwide right, title and interest to any such Inventions, and Optionee agrees to perform,
during and after employment, all acts deemed necessary or desirable by the Company to permit and assist the Company in registering, recording,
obtaining, maintaining, defending, enforcing and assigning Inventions or works made for hire in any and all countries. Optionee hereby
irrevocably designates and appoints the Company and its duly authorized officers and agents as Optionee’s agents and attorneys in
fact to act for and in Optionee’s behalf and instead of Optionee, to execute and file any documents and to do all other lawfully
permitted acts to further the above purposes with the same legal force and effect as if executed by Optionee. The foregoing designation
and appointment shall constitute an irrevocable power of attorney and are, and are deemed by the Company and Optionee to be, coupled with
an interest.

 

     

     

    

 

		(vi)	Without limiting the generality of any other provision of this Section 7(b), Optionee hereby
authorizes the Company and its Subsidiaries (and their successors and assigns) to make any desired changes to any part of any Invention,
to combine it with other materials in any manner desired, and to withhold Optionee’s identity in connection with any distribution
or use thereof alone or in combination with other materials.

 

		(vii)	This Section 7(b) does not apply to any invention for which no equipment, supplies, facility
or trade secret information of the Company or its Subsidiaries was used and which was developed entirely on Optionee’s own time,
unless (1) the invention relates (a) to the business of the Company or its Subsidiaries or (b) to the Company’s or
its Subsidiaries’ actual demonstrably anticipated research or development; or (2) the invention results from any work performed
by Optionee for the Company and its Subsidiaries.

 

		(viii)	The obligations of Optionee set forth in this Section 7(b) (including, but not limited
to, the assignment obligations) will be binding upon Optionee and Optionee’s executors, administrators and other representatives.

 

		(ix)	Optionee represents that he has made no Inventions prior to employment by the Company and its Subsidiaries.

 

		(c)	Cooperation. Optionee agrees to cooperate with the AdTheorent Companies, whether during Optionee’s
employment with any AdTheorent Company or thereafter, to (i) upon reasonable notice by the Company, voluntarily provide thorough
and accurate information and testimony to and on behalf of the AdTheorent Companies regarding (A) any investigation, litigation,
or claims initiated by, or brought or threatened against, any AdTheorent Company, including, but not limited, to meetings with any AdTheorent
Company’s counsel and testifying at depositions, trials, or other proceedings and (B) any dispute between any AdTheorent Company
and any other person or entity arising from or related to any act or omission that actually or allegedly occurred during Optionee’s
employment by any AdTheorent Company; (ii) reasonably accommodate his or her schedule to cooperate with any AdTheorent Company and
its counsel with respect to any such matters; and (iii) except as may be required by law, not disclose to anyone who is not directing
or assisting an AdTheorent Company in any such investigation, litigation, claim, or dispute, other than Optionee’s attorney, the
fact of or subject matter of the investigation, litigation, claim, or dispute; provided, however, that: (x) the Company
shall, to the full extent permitted by law, reimburse Optionee for reasonable travel, legal and other similar out-of-pocket expenses that
Optionee incurs in connection with providing such information or assistance after the termination of his or her employment with all AdTheorent
Companies that are approved in advance and in writing by the Company and supported by documentation promptly supplied by Optionee that
is reasonably deemed adequate by the Company; and (y) in engaging in any conduct described in this Section 7(c) after
the termination of his or her employment with all AdTheorent Companies, Optionee shall not act in the capacity of an employee of any AdTheorent
Company, and such assistance shall not make Optionee eligible to participate in any AdTheorent Company’s employee benefit plans
or programs. Notwithstanding the foregoing, Optionee’s obligation to provide cooperation hereunder shall not unreasonably interfere
with Optionee’s current employment (if Optionee is no longer employed by the AdTheorent Companies) and any such cooperation shall
be subject to Optionee’s agreement on scheduling, which shall not be unreasonably withheld.

 

     

     

    

 

		(d)	Non-Compete, Non-Solicitation. Optionee acknowledges that in the course of his employment with
the Company or any of its Subsidiaries or Affiliates, or their predecessors or successors, he has been or will be given access to and
has or will become familiar with their trade secrets and with other Confidential Information. If any of such Confidential Information
is disclosed to or used by competitors or potential competitors, such disclosure would cause irreparable harm to the Company, and as a
result, Optionee and the Company desire to provide the Company with adequate protection from the unauthorized disclosure or use of such
Confidential Information. In addition, the Optionee acknowledges that: (i) the Company and its Subsidiaries are and will be engaged
in the Business (as defined below) during the Employment Period and thereafter; (ii) Optionee is one of a limited number of persons
who is and will be developing the Business and will, during the Employment Period, have frequent and prolonged interactions with all customers
of the Company and its Subsidiaries with respect to matters significantly affecting the business relationship between those customers
and the Company and its Subsidiaries; (iii) the agreements and covenants contained in this Section 7(d) are essential
to protect the Company and its Subsidiaries and the goodwill of the Business and are a condition precedent to the Company entering into
this Agreement; (iv) Optionee’s employment with the Company has special, unique and extraordinary value to the Company and
its Subsidiaries and the Company and its Subsidiaries would be irreparably damaged if Optionee were to provide services to any person
or entity in violation of the provisions of this Agreement and (v) Optionee agrees that he will not challenge the reasonableness
of the Noncompete Period (as defined below), the Nonsolicit Period (as defined below) and the Restricted Territories (as defined below)
or the scope of coverage in any suit or proceeding regarding this Section 7(d), regardless of who initiates such suit or proceeding.
Therefore, and in further consideration of the compensation to be paid to Optionee hereunder and in connection with his employment, and
to protect the Company’s and its Subsidiaries’ and Affiliates’ Confidential Information, business interests and goodwill:

 

		(i)	Optionee agrees that, during the term of his employment with the Company, its Subsidiaries or Affiliates,
including employment following the expiration or termination (for any reason) of the Employment Period, and for one (1) year thereafter
(the “Noncompete Period”), he shall not directly or indirectly (whether as an owner, partner, shareholder, member,
agent, officer, director, manager, employee, independent contractor, consultant, or otherwise) own any interest in, manage, control, participate
in, consult with, render services for, become employed by, or in any manner engage in any business competing with the businesses of the
Company or its Subsidiaries or Affiliates, including, without limitation, the selling, designing and executing of mobile or cross device
media advertising campaigns utilizing predictive targeting, user identification and other targeting and optimization methods and the providing
of solutions for cross device tracking and attribution measurement and tracking, and any other businesses as they exist or are in process
during the course of Optionee’s employment with the Company, its Subsidiaries or Affiliates and on the date of the termination or
expiration of the Optionee’s employment with the Company, its Subsidiaries or Affiliates, within any geographical area in which
the Company or its Subsidiaries or Affiliates engage or have immediate plans to engage in such businesses, including in the Restricted
Territories (the “Business”). “Restricted Territories” shall mean North America. Nothing contained
in this Section 7(d)(i) shall be construed to prevent Optionee from investing in the stock of any corporation listed
on a national securities exchange or traded in the over the counter market, but only if Optionee is not involved in the business of said
corporation and if Optionee and Optionee’s associates (as such term is defined in Regulation 14(A) promulgated under the Securities
Exchange Act of 1934, as then in effect), collectively, do not own more than an aggregate of two percent of the stock of such corporation.

 

     

     

    

 

		(ii)	During and for a period of one (1) year after termination of the Optionee’s employment with
the Company, its Subsidiaries or Affiliates, including employment following the expiration or termination (for any reason) of the Employment
Period and for one year thereafter (the “Nonsolicit Period”), Optionee shall not directly or indirectly (whether as
an owner, partner, shareholder, member, agent, officer, director, manager, employee, independent contractor, consultant, or otherwise):
(i) induce or attempt to induce any officer, employee or consultant of the Company or any of its Subsidiaries or Affiliates to leave
the Company or such Subsidiary or Affiliate, or in any way interfere with the relationship between the Company or any of its Subsidiaries
or Affiliates and any officer, employee or consultant thereof, (ii) hire any person who was an officer, employee or consultant of
the Company or any Subsidiary or Affiliate at the date of termination of the Optionee’s employment with the Company, or any of its
Subsidiaries or Affiliates or at any time during the twelve-month period immediately prior to the date of the termination of the Optionee’s
employment with the Company, its Subsidiaries or Affiliates (it being conclusively presumed by the parties so as to avoid any disputes
under this Section 7(d)(ii) that any such hiring within such twelve-month period is in violation of clause (i) above),
(iii) call on, solicit or provide any products or services to any customer, supplier, distributor, licensee, licensor, franchisee
or other business relation of the Company or any of its Subsidiaries or Affiliates (including any Person that was a customer, supplier
or other potential business relation of the Company, or any of its Subsidiaries or Affiliates at any time during the twelve-month period
immediately prior to such call, solicitation or service), or induce or attempt to induce such Person to cease doing business with the
Company or any of its Subsidiaries or Affiliates or (iv) in any way interfere with the relationship between any customer, supplier,
distributor, licensee, licensor, franchisee, or other business relation of the Company or any of its Subsidiaries or Affiliates (including,
without limitation, making any negative or disparaging statements or communications regarding the Company or any of its Subsidiaries or
Affiliates).

 

     

     

    

 

		(iii)	The Optionee understands that the foregoing restrictions may limit his ability to earn a livelihood in
a business similar to the business of the Company and its Subsidiaries or Affiliates, but he nevertheless believes that he has received
and will receive sufficient consideration and other benefits as an executive, a managerial or a key employee of the Company and as otherwise
provided hereunder to clearly justify such restrictions which, in any event (given his education, skills and ability), the Optionee does
not believe would prevent him from otherwise earning a living. Optionee acknowledges that the Company’s and its Subsidiaries’
and Affiliates’ businesses have been conducted or will soon be conducted throughout the Restricted Territories and that the geographic
restrictions and time periods, as well as all other restrictions and covenants in this Section 7(d) are reasonable and
necessary, and supported by good and valuable consideration, in order to protect a protectable interest of the Company’s, and its
Subsidiaries’ and Affiliates’ businesses, and that Optionee has reviewed the provisions of this Agreement with his legal counsel.
In addition, during the Noncompete Period, Optionee shall provide a copy of this Agreement, including, without limitation, Sections
7(a) through (d), to any prospective or subsequent employer or other person in connection with any employment or consulting
services to be performed by Optionee such that any such employer or other person is aware of and has a copy of the restrictions and other
obligations, terms and conditions set forth in such sections. Upon request from time to time by the Company, Optionee shall furnish the
Company with a true and complete certificate specifying compliance with this Section 7(d), and Optionee hereby authorizes
the Company at its reasonable discretion to contact any such prospective or subsequent employer or other person and inform them of this
Agreement or any other applicable and relevant policy or agreement between Optionee and the Company or its Affiliates or Subsidiaries
that may be in effect at the time that Optionee’s employment with the Company or its Affiliates or Subsidiaries ends.

 

		(iv)	If, at the time of enforcement of this Section 7(d), a court or arbiter shall hold that the
duration, scope or area restrictions stated herein are unreasonable under circumstances then existing, the parties agree that the maximum
duration, scope or area reasonable under such circumstances shall be substituted for the stated duration, scope or area and that the court
shall be allowed to revise the restrictions contained herein to cover the maximum period, scope and area permitted by law.

 

     

     

    

 

 

 

		(v)	In the event of the breach or a threatened breach by Optionee of any of the provisions of this Section 7(d),
the Company (and/or its Subsidiaries or Affiliates), in addition and supplementary to other rights and remedies existing in its (or their)
favor, shall be entitled to specific performance of this Section 7(d), including temporary, preliminary and/or permanent injunctive
or other equitable relief from a court of competent jurisdiction in order to stop and/or prevent any violations of the provisions hereof
(without posting a bond or other security), and shall also be entitled to require the Optionee to account for and pay over to the Company
(and/or its Subsidiaries or Affiliates) all compensation, profits, moneys, accruals, increments or other benefits derived from or received
as a result of any transactions constituting a breach of the covenants contained herein, and shall also be entitled to require Optionee
to repay any severance payments, gains on equity (including stock options) and other compensation and forfeit all equity (including stock
options) in any parent of the Company, paid or issued, as applicable, by the Company, or its Subsidiaries or their Affiliates. In addition,
in the event of an alleged breach or violation by Optionee of this Section 7(d), the restricted periods set forth in this
Section 7(d) shall be tolled until such breach or violation has been duly cured.

 

		8.	Definitions.

 

“Cause”
has the meaning set forth in any unexpired employment agreement between the Company and Optionee. In the absence of such agreement, “Cause”
means the Operating Board’s good faith determination that Optionee has (i) committed a felony or other crime involving moral
turpitude or the commission of any other act or omission involving theft, dishonesty, disloyalty or fraud with respect to the Company
or any of its Subsidiaries or any clients, customers, suppliers, vendors or employees of the Company or any of its Subsidiaries (or any
act that materially and negatively effects the business, integrity, character or reputation of the Company, any of its Subsidiaries or
any clients, customers, suppliers, vendors or employees of the Company or any of its Subsidiaries), (ii) reported to work intoxicated
or under the influence of illegal drugs, the use of illegal drugs (whether or not at the workplace) or other conduct causing the Company
or any of its Subsidiaries or Affiliates substantial public disgrace or disrepute or economic harm, (iii) substantially and repeatedly
failed to follow the policies, procedures and guidelines of the Company or any of its Subsidiaries (including with respect to sexual harassment
or inappropriate relationships with other employees) or substantial and repeated failure to perform duties as reasonably directed by the
Operating Board, in each case which is not cured to the Operating Board’s reasonable satisfaction within 30 days after written notice
thereof to Optionee, to the extent that such breach is capable of being cured, (iv) committed a breach of fiduciary duty, gross negligence
or willful misconduct with respect to the Company or any of its Subsidiaries or Affiliates, (v) engaged in any conduct that materially
and negatively affects Optionee’s own integrity, character or reputation (including Optionee’s reputation with any clients,
customers, suppliers, vendors or employees of the Company or any of its Subsidiaries) so as to cause Optionee to be unfit to act in any
capacity in which Optionee currently serves the Company or any of its Subsidiaries, (vi) committed chronic absenteeism (“chronic
absenteeism” shall be deemed to have occurred if Optionee has at least ten absences unrelated to disability or illness or scheduled
vacation in any ten-week period, or (vii) committed any other material breach of this Agreement which is not cured to the Operating
Board’s reasonable satisfaction within 15 days after written notice thereof to Optionee, to the extent that such breach is reasonably
capable of being cured. If Optionee’s employment ends for any reason other than discharge by the Company for Cause, but at a time
when the Company had Cause to terminate Optionee (or would have had Cause if it knew all relevant facts), Optionee’s termination
shall be treated as a discharge by the Company for Cause.

 

     

     

    

 

“Covered Entity”
means every Affiliate of Optionee, and every business, association, trust, corporation, partnership, limited liability company, proprietorship
or other entity in which Optionee, his or her spouse or any of his or her children has a direct or indirect ownership interest other than
any corporation listed on a national securities exchange or traded in the over-the-counter market, provided that Optionee is not directly
or indirectly involved in the business of said corporation and further provided that Optionee and Optionee’s associates (as such
term is defined in Regulation 14(A) promulgated under the Securities Exchange Act of 1934, as in effect on the date hereof), collectively,
do not own more than an aggregate of two percent (2%) of the stock of such corporation.

 

“Disability”

duties and obligations to the Company or to participate effectively and actively in the management of the Company for a period of at least
90 consecutive days or for shorter periods aggregating at least 120 days (whether or not consecutive) during any twelve-month period,

modified from time to time in accordance with its terms).

all Participant Interests shall continue to be Participant Interests in the hands of any holder other than Optionee (except for the Company)
and, except as otherwise provided herein or in the Operating Agreement, each such other holder of Participant Interests shall succeed
to all rights and obligations attributable to Optionee as a holder of Participant Interests hereunder. Participant Interests shall also

		10.	General Provisions.

 

		(a)	Severability and Judicial Modification. Whenever possible, each provision of this Agreement will
be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Agreement is held to be
invalid, illegal or unenforceable in any respect under any applicable law or rule in any jurisdiction, such invalidity, illegality
or unenforceability will not affect any other provision or any other jurisdiction, but this Agreement will be reformed, construed and
enforced in such jurisdiction as if such invalid, illegal or unenforceable provision had never been contained herein.

 

     

     

    

 

		(b)	Complete Agreement. This Agreement and those documents expressly referred to herein (including,
but not limited to, the Plan and the Operating Agreement) embody the complete agreement and understanding among the parties hereto and
supersede and preempt any prior understandings, agreements or representations by or among the parties hereto, written or oral, which may
have related to the subject matter hereof in any way; provided, however, that the restrictive covenants contained in this
Agreement shall be in addition to, and not in lieu of, and shall not in any way limit the enforceability of, any restrictive covenant
covering similar subject matter contained in any other agreement to which Optionee is a party.

 

		(c)	Counterparts. This Agreement may be executed in separate counterparts, each of which is deemed
to be an original and all of which taken together shall constitute one and the same agreement and shall become effective when one or more
counterparts have been signed by each of the parties hereto and delivered to the other. This Agreement and any amendments hereto, to the
extent signed and delivered by means of a facsimile machine or other electronic transmission (including transmission in portable document
format by electronic mail), shall be treated in all manner and respects and for all purposes as an original agreement and shall be considered
to have the same binding legal effect as if it were the original signed version thereof delivered in person.

 

		(d)	Successors and Assigns. Except as otherwise provided herein, this Agreement shall bind and inure
to the benefit of and be enforceable by Optionee, the Company, and their respective successors and assigns (including subsequent holders
of Participant Interests); provided that the rights and obligations of Optionee under this Agreement shall not be assignable except in
connection with a permitted transfer of Participant Interests under the Operating Agreement.

 

		(e)	Choice of Law. All other questions concerning the construction, validity, enforcement and interpretation
of this Agreement and the exhibits hereto shall be governed by the internal law, and not the law of conflicts, of the State of Delaware.

 

		(f)	Remedies. Each of the parties to this Agreement shall be entitled to enforce its rights under this
Agreement specifically, to recover damages and costs (including reasonable attorney’s fees) caused by any breach of any provision
of this Agreement and to exercise all other rights existing in its favor. The parties hereto agree and acknowledge that money damages
would not be an adequate remedy for any breach of the provisions of this Agreement and that the Company may in its sole discretion apply
to any court of law or equity of competent jurisdiction (without posting any bond or deposit, having to show that money damages will be
inadequate or impossible to determine or proving special damages or irreparable injury) for specific performance and/or other injunctive
relief in order to enforce or prevent any violations of the provisions of this Agreement. Optionee acknowledges, however, that no specification
in this Agreement of a specific legal or equitable remedy may be construed as a waiver of or prohibition against pursuing other legal
or equitable remedies in the event of a breach of this Agreement by Optionee. Optionee shall be liable for any breach by any Covered Entity
of this Agreement.

 

     

     

    

 

		(g)	No Strict Construction. The parties hereto have participated jointly in the negotiation and drafting
of this Agreement. In the event an ambiguity or question of intent or interpretation arises, this Agreement shall be construed as if drafted
jointly by the parties hereto, and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue of the authorship
of any of the provisions of this Agreement.

 

		(h)	Amendment and Waiver. The provisions of this Agreement may be amended and waived only with the
prior written consent of the Company (with approval by the Operating Board) and Optionee; provided, however, that the Company
(with approval by the Operating Board) may amend this Agreement without the consent of Optionee if such amendment does not materially
and adversely affect the Optionee in a manner that is disproportionate to the other Interest Holders.

 

		(i)	Business Days. If any time period for giving notice or taking action hereunder expires on a day
which is a Saturday, Sunday or legal holiday in the state in which the Company’s chief executive office is located, the time period
shall be automatically extended to the business day immediately following such Saturday, Sunday or holiday.

 

		(j)	Withholding. The Company shall be entitled, if necessary or desirable, to withhold from you from
any amounts due and payable by the Company to you (or secure payment from you in lieu of withholding) the amount of any withholding or
other tax due from the Company with respect to any Option Shares issuable under this Plan, and the Company may defer such issuance unless
indemnified by you to its satisfaction.

 

		(k)	Adjustments. In the event of a reorganization, recapitalization, Interest dividend or Interest
split, or combination or other change in the Interest, the Operating Board may, in order to prevent the dilution or enlargement of rights
under outstanding Options, make such adjustments in the number and type of Participant Interests authorized hereunder and the Exercise
Price specified herein as may be determined to be appropriate and equitable.

This PARTICIPANT INTEREST
AGREEMENT (this “Agreement”) is made as of February 15, 2018, between AdTheorent Holding Company, LLC, a Delaware

Optionee is executing this
Agreement in connection with Optionee’s receipt of Options (as defined below) pursuant to the AdTheorent Holding Company, LLC 2017
Interest Option Plan (the “Plan”), and employment with the Company and/or its Subsidiaries. Certain capitalized terms
used herein are defined in Section 8 hereof. All capitalized terms not otherwise defined herein shall have the meanings set

This Agreement provides for
the issuance to Optionee of options (each an “Option” and collectively, the “Options”) to purchase
that number of Non-Voting Class C Interests set forth on the signature page hereto (collectively, the “Participant
Interests”) subject to the terms and conditions set forth herein and in the Operating Agreement.

 

The parties hereto agree as
follows:

 

		1.	Grant of Options.

 

		(a)	Issuance. Upon the date hereof (the “Grant Date”), the Company shall grant to Optionee,
and Optionee shall accept, Options to purchase from the Company the Participant Interests. For purposes of this Agreement, all of the
Options set forth as such on the signature page hereto shall be designated “Time Options.” For each Participant
Interest purchased in accordance with the terms of this Agreement, the Plan and the Operating Agreement, Optionee shall pay to the Company
the price set forth on the signature page hereto (the “Exercise Price”).

 

		(b)	Representations and Warranties of Optionee. In connection with the issuance of the Options hereunder,
Optionee represents and warrants to the Company that:

applicable state securities laws;

 

		(ii)	Optionee is an executive, a managerial or a key employee of the Company and/or its Subsidiaries;

 

		(iii)	Optionee understands that the Participant Interests have not been registered under the Securities Act
and, therefore, cannot be sold unless subsequently registered under the Securities Act or an exemption from such registration is available;

 

     

     

    

 

		(iv)	Optionee has had an opportunity to ask questions and receive answers concerning the terms and conditions

or cause a breach of any agreement, contract or instrument to which Optionee is a party or any judgment, order or decree to which Optionee
is subject; and

 

		(vi)	Optionee is a resident of the state set forth on the signature page hereto.

 

		(c)	As an inducement to the Company to grant the Options to Optionee and as a condition thereto, Optionee
acknowledges and agrees that:

 

		(i)	none of the grant of the Options, the issuance of the Participant Interests to Optionee or any provision
contained herein shall entitle Optionee to remain in the employment of any AdTheorent Company or affect the right of the AdTheorent Companies
to terminate Optionee’s employment at any time, for any reason or no reason, with or without Cause; and

 

		(ii)	except as otherwise provided by the Plan or the Operating Agreement or non-waiveable provisions of applicable
law, the Company shall have no duty or obligation to disclose to Optionee, and Optionee shall have no right to be advised of, any material
information regarding the Company or any of its Subsidiaries at any time.

 

		(d)	The parties hereto acknowledge and agree that the Options granted and any Participant Interests issued
pursuant to this Agreement are being offered to Optionee in consideration of the services rendered to the Company and its Subsidiaries
as additional compensation under a “written compensation contract” as contemplated by Rule 701 of the Securities Act.

 

		2.	Restrictions on Transfer and Repurchase Rights. The Options and the Participant Interests shall
be subject to the restrictions on Transfer set forth in the Operating Agreement and the repurchase rights set forth in Section 6.

following a termination of employment for any other reason (including resignation by the Optionee). Except as set forth in Section 3(b) below,

at any time after the expiration of the Option Period and the Optionee (and his or her successors) shall have no rights whatsoever with
respect to any Options from and after such termination and cancellation.

 

		(b)	Upon the termination of Optionee’s employment with the AdTheorent Companies (i) in connection

however, that, if Optionee is, and has been continuously, employed by an AdTheorent Company from the date hereof through the
consummation of a Sale of the Company, then upon such Sale of the Company, all of the remaining Time Options shall become vested and exercisable;
provided further that in the event the Time Options become vested and exercisable upon a Sale of the Company and the purchase price
paid by the buyer in connection with such Sale of the Company which is allocated to each Participant Interest is less than the Exercise
Price of any portion of the Participant Interests issued hereunder, such Participant Interests shall be deemed forfeited and canceled
and shall have no further force or effect upon consummation of such Sale of the Company. Notwithstanding the foregoing, in all cases vesting
of the Time Options shall cease upon the termination of Optionee’s employment with the AdTheorent Companies.

 

		(b)	“Vested Options” shall mean Time Options that have become vested and exercisable pursuant
to the terms of this Agreement. “Unvested Options” shall mean Time Options that have not become Vested Options pursuant
to the terms of this Agreement.

 

		5.	Exercise.

 

		(a)	Vested Options may be exercised in whole or in part upon payment of an amount (the “Option Price”)
equal to the product of (i) the Exercise Price multiplied by (ii) the number of Participant Interests to be acquired. Payment
shall be made in cash (including check); provided, however, that solely to the extent an Option is being exercised in contemplation
of and contingent upon a Sale of the Company, where the Participant Interests acquired by Optionee are to be sold or transferred in connection
with such Sale of the Company, then, at Optionee’s option, Optionee may exercise the Option by surrender of the Option to the Company
in exchange for that number of Participant Interests issuable upon such exercise less a number of Participant Interests having an aggregate
Fair Market Value equal to the aggregate Exercise Price payable for the portion of the Option being exercised (in each case, subject to
adjustment and withholding for required taxes and withholdings).

 

		(b)	Optionee acknowledges and agrees that, in connection with the exercise of Vested Options pursuant to the
terms of his Agreement, Optionee shall be bound by the terms of, and subject to the conditions set forth in, the Operating Agreement,
including, without limitation, the drag-along and related obligations set forth therein upon a Sale of the Company.

 

		(c)	To the extent permitted to do so hereunder, Vested Options may be exercised by delivering (i) written
notice to the Company (to the attention of the Company’s Secretary) and Optionee’s written acknowledgment that Optionee has
read and been afforded an opportunity to ask questions of management of the Company regarding all financial and other information provided
to Optionee regarding the Company, together with payment of the Exercise Price in accordance with the provisions of Section 5(a) above,
(ii) an executed Joinder Agreement to the Operating Agreement in the form of Exhibit B hereto and (ii) an executed
spousal consent (if applicable) in the form of Exhibit C hereto and (iii) all other agreements and documents as the Company
may reasonably request. As a condition to any exercise of any Vested Option, Optionee shall permit the Company to deliver to Optionee
all financial and other information regarding the Company it believes necessary to enable Optionee to make an informed investment decision,
and Optionee shall make all customary investment representations which the Company requires.

 

     

     

    

 

		(d)	Section 83(b). Within 30 days after the date of any exercise of Options, Optionee shall
make an effective election with the Internal Revenue Service under Section 83(b) of the Internal Revenue Code and the regulations
promulgated thereunder in the form of Exhibit D attached hereto. Option shall also include a copy of such election in its
current year’s tax return.

 

		6.	Repurchase Option.

 

		(a)	Upon the death, Disability or termination or expiration for any other reason of Optionee’s employment
or independent contractor relationship with, or service to, the AdTheorent Companies (each, a “Termination Event”),
the Company shall have the right, but not the obligation, to purchase all or any portion of the Participant Interests held by any member
of Optionee’s Member Group (all such Participant Interests, collectively, the “Repurchased Interests”; and such
members of Optionee’s Member Group, collectively, the “Repurchase Sellers”) at a price per Participation Interest
equal to the Repurchase Price for each such Participation Interest by delivering a written notice of such election to the Repurchase Sellers
within 120 days after the occurrence of such Termination Event (the date of such written notice, the “Repurchase Notice Date”).
The “Repurchase Price” for the Repurchased Interests shall mean (i) their Fair Market Value if such termination
occurred as a result of the death or Disability of Optionee or the termination of Optionee’s employment or independent contractor
relationship with, or service to, the AdTheorent Companies by a AdTheorent Company without Cause, or (B) $1.00 (one dollar) in the
aggregate for all Repurchased Interests if the termination or expiration of Optionee’s employment or independent contractor relationship
with, or service to, the AdTheorent Companies occurred for any other reason.

 

		(b)	The Company may assign its rights under this Section 6 to one or more Voting Members. If more
than one eligible Voting Member elects to purchase the Repurchased Interests, they may do so pro rata based on the number of Voting Class A
Interests held by each of them or in such other proportions as they may agree. No member of a Member Group of Optionee shall be eligible
to purchase any Repurchased Interests under this Section 6.

 

     

     

    

 

		(c)	If the Company elects to purchase any Repurchased Interests pursuant to this Section 6, to
the extent permitted by the AdTheorent Companies’ credit facilities in effect from time to time and applicable law and to the extent
the Company has cash available, the purchase price shall be payable in cash with the balance of the purchase price to be paid in the form
of an unsecured fully subordinated promissory note issued by the Company (i) bearing interest at a fixed rate equal to the “prime
rate” as published in The Wall Street Journal on the Repurchase Notice Date and (ii) (A) maturing in whole or in part,
as applicable, on the earliest date on which the foregoing conditions are satisfied as to all or any portion of the note balance and (B) to
the extent not earlier repaid, maturing in whole upon the bankruptcy or insolvency of the Company. The applicable Repurchase Seller and
its successors and assigns will, from time to time, execute such reasonable subordination agreements as are requested by any AdTheorent
Company’s current and future lenders. If a Voting Member elects to purchase any Repurchased Interests pursuant to this Section 6,
the purchase price with respect to such Repurchased Interests shall be payable in cash or such other form of consideration agreed to by
the parties.

 

		(d)	The Company and/or eligible Voting Members, as applicable, will designate in writing to the Repurchase
Sellers, the time, date and place of any purchase under this Section 6, provided that such purchase shall occur within thirty
(30) days of the date of the election by the Company and/or such Voting Members, as applicable, to consummate such transaction. At the
closing of a purchase pursuant to this Section 6, each Repurchase Seller shall make such representations and warranties relating
to the sale, transfer and ownership of such Repurchased Interests and execute and deliver such other documents and instruments, as the
Company and/or Voting Members, as applicable, may reasonably request, including, but not limited to, a representation and warranty that
each such Repurchase Seller is conveying to the Company and/or Voting Members, as applicable, all of the Repurchased Interests free and
clear of all liens, claims and encumbrances, except for those liens, claims and encumbrances set forth in the Operating Agreement. If
the Company and/or Voting Members, as applicable, shall be ready, willing and able, at the time and place and in the amount and form provided
in this Section 6 to deliver the consideration for any Repurchased Interests to be purchased in accordance with this Section 6
and a Repurchase Seller shall not comply with its obligations hereunder, then from and after such time, such Repurchase Seller shall no
longer have any rights as an Interest Holder or otherwise with respect to such Repurchased Interests (other than the right to receive
payment of the Repurchase Price in accordance with this Section 6), and such Repurchased Interest shall be deemed purchased
in accordance with the applicable provisions hereof and the Company and/or Voting Members, as applicable, shall be deemed the owner and
holder of such Repurchased Interest.

 

     

     

    

 

		7.	Confidentiality; Restrictive Covenants; Other Agreements.

 

		(a)	Confidential Information.

 

		(i)	Optionee acknowledges that all Confidential Information (as defined below) obtained by him while employed
by the Company or its Subsidiaries or Affiliates concerning the business or affairs of the Company or any Subsidiary or Affiliate are
the property of the Company or such Subsidiary or Affiliate and constitute a protectable business interest of the Company and its Subsidiaries
or Affiliates. Optionee acknowledges that the Confidential Information has been generated at great effort and expense by the Company,
its Subsidiaries and Affiliates and their predecessors, and has been reasonably maintained in a confidential manner by such persons and
entities. Optionee does not claim any rights to or lien on any Confidential Information. Optionee will immediately notify the Company
of any unauthorized possession, use, disclosure, copying, removal or destruction, or attempt thereof, of any Confidential Information
by anyone of which the Optionee becomes aware and of all details thereof. Optionee shall take all reasonably appropriate steps to safeguard
(including by abiding by all Company and Subsidiary policies with respect to) Confidential Information and to protect it against disclosure,
misuse, espionage, loss and theft. Therefore, Optionee agrees that he shall not disclose, furnish, make available or utilize, directly
or indirectly, any Confidential Information without the prior written consent of the Operating Board, unless and to the extent that the
Confidential Information becomes generally known to and available for use by the public other than as a result of Optionee’s acts
or omissions. Optionee shall deliver to the Company at the termination or expiration of his employment with the Company, or its Subsidiaries
or Affiliates, or at any other time the Company may request, all memoranda, notes, plans, records, reports, computer tapes, computers,
printouts and software and other documents and data (and copies thereof) embodying or relating to the Confidential Information, Inventions
(as defined below) or the business of the Company, or any of its Subsidiaries, or Affiliates which he may then possess or have under his
control.

 

		(ii)	As used in this Agreement, the term “Confidential Information” means any and all confidential,
proprietary or trade secret information, whether disclosed, directly or indirectly, verbally, in writing or by any other means in tangible
or intangible form, including that which is conceived or developed by Optionee, applicable to or in any way related to: (i) the present
or future business and assets of the Company and its Subsidiaries and Affiliates; (ii) the research and development of the Company
and its Subsidiaries and Affiliates; or (iii) the business of any client, customer, supplier, vendor or other business relation of
the Company and its Subsidiaries and Affiliates. Such Confidential Information includes the following property or information of the Company
and its Subsidiaries and Affiliates, by way of example and without limitation, trade secrets, processes, formulas, data, program documentation,
customer lists, designs, drawings, algorithms, source code, object code, know-how, improvements, inventions, licenses, techniques, all
plans or strategies for marketing, development and pricing, business plans, financial statements, profit margins and all information concerning
existing or potential clients, suppliers, employees and vendors. Confidential Information of the Company and its Subsidiaries and Affiliates
also means all similar information disclosed to the Company and its Subsidiaries and Affiliates by third parties which is subject to confidentiality
obligations. Notwithstanding the foregoing, the provisions of this Section 7(a) shall not apply in the following circumstances:
(1) when disclosure of Confidential Information is required by law or by any court, arbitrator, mediator or administrative or legislative
body; provided, that prior to such disclosure Optionee shall provide to the Company and its Subsidiaries and Affiliates prompt
notice of such required disclosure to enable such entities to seek a protective order or other relief, and reasonably cooperate with the
such entities in connection with seeking any such order or other relief; or (2) with respect to Confidential Information that becomes
generally known to the public other than due to (A) Optionee’s violation of this Agreement or any other obligation or duty
to the Company, its Subsidiaries or Affiliates or (B) a disclosure by a third party who owes the Company, its Subsidiaries or its
Affiliates an obligation of confidence in relation to such Confidential Information.

 

     

     

    

 

		(iii)	During the term of Optionee’s employment with the Company, its Subsidiaries or Affiliates, including
the period following the expiration of the Employment Period, Optionee shall be prohibited from using or disclosing any confidential information
or trade secrets that Optionee may have learned through any prior employment. If at any time during his employment with the Company or
any Subsidiary or Affiliate, Optionee believes he is being asked to engage in work that will, or will be likely to, jeopardize any confidentiality
or other obligations Optionee may have to former employers or other parties, Optionee shall immediately advise the Operating Board and
provide it with documents pertaining thereto. Optionee represents and warrants that he is not aware of any confidential information or
trade secrets of any prior employers that he will need or rely on in carrying out his duties and responsibilities hereunder.

 

		(iv)	Notwithstanding the foregoing, pursuant to 18 U.S.C. § 1833(b)(1): “An
individual shall not be held criminally or civilly liable under any federal or state trade secret law for the disclosure of a trade secret
that (A) is made (i) in confidence to a federal, state, or local government official, either directly or indirectly, or to an
attorney; and (ii) solely for the purpose of reporting or investigating a suspected violation of law; or (B) is made in a complaint
or other document filed in a lawsuit or other proceeding, if such filing is made under seal.” Any employee, contractor or consultant
who is found to have wrongfully misappropriated trade secrets may be liable for, among other things, exemplary damages and attorneys’
fees.

 

     

     

    

 

		(b)	Inventions, Patents and Intellectual Property.

 

		(i)	Optionee covenants and agrees that all Inventions (as defined below) shall be the sole and exclusive property
of the Company and its Subsidiaries.

 

		(ii)	As used in this Agreement, the term “Inventions” means any and all inventions, developments,
discoveries, improvements, works of authorship, concepts or ideas, or expressions thereof, whether or not subject to patents, copyright,
trademark, trade secret protection or other intellectual property right protection (in the United States or elsewhere), and whether or
not reduced to practice, conceived or developed by Optionee while employed with the Company or within one year following termination of
such employment, which relate to or result from the actual or anticipated business, work, research or investigation of the Company and
its Subsidiaries or which are suggested by or result from any task assigned to or performed by Optionee for the Company and its Subsidiaries
or any of its Affiliates.

 

		(iii)	Optionee acknowledges that all original works of authorship which are made by him (solely or jointly)
are works made for hire under the United States Copyright Act (17 U.S.C., et seq.).

 

		(iv)	Optionee agrees to promptly disclose to the Company all Inventions and all work product relating thereto.
This disclosure will include complete and accurate copies of all source code, object code or machine readable copies, documentation, work
notes, flow charts, diagrams, test data, reports, samples and other tangible evidence or results (collectively, “Tangible Embodiments”)
of such Inventions and related work product. All Tangible Embodiments of any Invention or work product related thereto will be deemed
to have been assigned to the Company (or any applicable Subsidiary) as a result of the act of expressing any Invention therein.

 

		(v)	Optionee hereby assigns to the Company (together with the right to prosecute or sue for infringements
or other violations of the same) the entire worldwide right, title and interest to any such Inventions, and Optionee agrees to perform,
during and after employment, all acts deemed necessary or desirable by the Company to permit and assist the Company in registering, recording,
obtaining, maintaining, defending, enforcing and assigning Inventions or works made for hire in any and all countries. Optionee hereby
irrevocably designates and appoints the Company and its duly authorized officers and agents as Optionee’s agents and attorneys in
fact to act for and in Optionee’s behalf and instead of Optionee, to execute and file any documents and to do all other lawfully
permitted acts to further the above purposes with the same legal force and effect as if executed by Optionee. The foregoing designation
and appointment shall constitute an irrevocable power of attorney and are, and are deemed by the Company and Optionee to be, coupled with
an interest.

 

     

     

    

 

		(vi)	Without limiting the generality of any other provision of this Section 7(b), Optionee hereby
authorizes the Company and its Subsidiaries (and their successors and assigns) to make any desired changes to any part of any Invention,
to combine it with other materials in any manner desired, and to withhold Optionee’s identity in connection with any distribution
or use thereof alone or in combination with other materials.

 

		(vii)	This Section 7(b) does not apply to any invention for which no equipment, supplies, facility
or trade secret information of the Company or its Subsidiaries was used and which was developed entirely on Optionee’s own time,
unless (1) the invention relates (a) to the business of the Company or its Subsidiaries or (b) to the Company’s or
its Subsidiaries’ actual demonstrably anticipated research or development; or (2) the invention results from any work performed
by Optionee for the Company and its Subsidiaries.

 

		(viii)	The obligations of Optionee set forth in this Section 7(b) (including, but not limited
to, the assignment obligations) will be binding upon Optionee and Optionee’s executors, administrators and other representatives.

 

		(ix)	Optionee represents that he has made no Inventions prior to employment by the Company and its Subsidiaries.

 

		(c)	Cooperation. Optionee agrees to cooperate with the AdTheorent Companies, whether during Optionee’s
employment with any AdTheorent Company or thereafter, to (i) upon reasonable notice by the Company, voluntarily provide thorough
and accurate information and testimony to and on behalf of the AdTheorent Companies regarding (A) any investigation, litigation,
or claims initiated by, or brought or threatened against, any AdTheorent Company, including, but not limited, to meetings with any AdTheorent
Company’s counsel and testifying at depositions, trials, or other proceedings and (B) any dispute between any AdTheorent Company
and any other person or entity arising from or related to any act or omission that actually or allegedly occurred during Optionee’s
employment by any AdTheorent Company; (ii) reasonably accommodate his or her schedule to cooperate with any AdTheorent Company and
its counsel with respect to any such matters; and (iii) except as may be required by law, not disclose to anyone who is not directing
or assisting an AdTheorent Company in any such investigation, litigation, claim, or dispute, other than Optionee’s attorney, the
fact of or subject matter of the investigation, litigation, claim, or dispute; provided, however, that: (x) the Company
shall, to the full extent permitted by law, reimburse Optionee for reasonable travel, legal and other similar out-of-pocket expenses that
Optionee incurs in connection with providing such information or assistance after the termination of his or her employment with all AdTheorent
Companies that are approved in advance and in writing by the Company and supported by documentation promptly supplied by Optionee that
is reasonably deemed adequate by the Company; and (y) in engaging in any conduct described in this Section 7(c) after
the termination of his or her employment with all AdTheorent Companies, Optionee shall not act in the capacity of an employee of any AdTheorent
Company, and such assistance shall not make Optionee eligible to participate in any AdTheorent Company’s employee benefit plans
or programs. Notwithstanding the foregoing, Optionee’s obligation to provide cooperation hereunder shall not unreasonably interfere
with Optionee’s current employment (if Optionee is no longer employed by the AdTheorent Companies) and any such cooperation shall
be subject to Optionee’s agreement on scheduling, which shall not be unreasonably withheld.

 

     

     

    

 

		(d)	Non-Compete, Non-Solicitation. Optionee acknowledges that in the course of his employment with
the Company or any of its Subsidiaries or Affiliates, or their predecessors or successors, he has been or will be given access to and
has or will become familiar with their trade secrets and with other Confidential Information. If any of such Confidential Information
is disclosed to or used by competitors or potential competitors, such disclosure would cause irreparable harm to the Company, and as a
result, Optionee and the Company desire to provide the Company with adequate protection from the unauthorized disclosure or use of such
Confidential Information. In addition, the Optionee acknowledges that: (i) the Company and its Subsidiaries are and will be engaged
in the Business (as defined below) during the Employment Period and thereafter; (ii) Optionee is one of a limited number of persons
who is and will be developing the Business and will, during the Employment Period, have frequent and prolonged interactions with all customers
of the Company and its Subsidiaries with respect to matters significantly affecting the business relationship between those customers
and the Company and its Subsidiaries; (iii) the agreements and covenants contained in this Section 7(d) are essential
to protect the Company and its Subsidiaries and the goodwill of the Business and are a condition precedent to the Company entering into
this Agreement; (iv) Optionee’s employment with the Company has special, unique and extraordinary value to the Company and
its Subsidiaries and the Company and its Subsidiaries would be irreparably damaged if Optionee were to provide services to any person
or entity in violation of the provisions of this Agreement and (v) Optionee agrees that he will not challenge the reasonableness
of the Noncompete Period (as defined below), the Nonsolicit Period (as defined below) and the Restricted Territories (as defined below)
or the scope of coverage in any suit or proceeding regarding this Section 7(d), regardless of who initiates such suit or proceeding.
Therefore, and in further consideration of the compensation to be paid to Optionee hereunder and in connection with his employment, and
to protect the Company’s and its Subsidiaries’ and Affiliates’ Confidential Information, business interests and goodwill:

 

		(i)	Optionee agrees that, during the term of his employment with the Company, its Subsidiaries or Affiliates,
including employment following the expiration or termination (for any reason) of the Employment Period, and for one (1) year thereafter
(the “Noncompete Period”), he shall not directly or indirectly (whether as an owner, partner, shareholder, member,
agent, officer, director, manager, employee, independent contractor, consultant, or otherwise) own any interest in, manage, control, participate
in, consult with, render services for, become employed by, or in any manner engage in any business competing with the businesses of the
Company or its Subsidiaries or Affiliates, including, without limitation, the selling, designing and executing of mobile or cross device
media advertising campaigns utilizing predictive targeting, user identification and other targeting and optimization methods and the providing
of solutions for cross device tracking and attribution measurement and tracking, and any other businesses as they exist or are in process
during the course of Optionee’s employment with the Company, its Subsidiaries or Affiliates and on the date of the termination or
expiration of the Optionee’s employment with the Company, its Subsidiaries or Affiliates, within any geographical area in which
the Company or its Subsidiaries or Affiliates engage or have immediate plans to engage in such businesses, including in the Restricted
Territories (the “Business”). “Restricted Territories” shall mean North America. Nothing contained
in this Section 7(d)(i) shall be construed to prevent Optionee from investing in the stock of any corporation listed
on a national securities exchange or traded in the over the counter market, but only if Optionee is not involved in the business of said
corporation and if Optionee and Optionee’s associates (as such term is defined in Regulation 14(A) promulgated under the Securities
Exchange Act of 1934, as then in effect), collectively, do not own more than an aggregate of two percent of the stock of such corporation.

 

     

     

    

 

		(ii)	During and for a period of one (1) year after termination of the Optionee’s employment with
the Company, its Subsidiaries or Affiliates, including employment following the expiration or termination (for any reason) of the Employment
Period and for one year thereafter (the “Nonsolicit Period”), Optionee shall not directly or indirectly (whether as
an owner, partner, shareholder, member, agent, officer, director, manager, employee, independent contractor, consultant, or otherwise):
(i) induce or attempt to induce any officer, employee or consultant of the Company or any of its Subsidiaries or Affiliates to leave
the Company or such Subsidiary or Affiliate, or in any way interfere with the relationship between the Company or any of its Subsidiaries
or Affiliates and any officer, employee or consultant thereof, (ii) hire any person who was an officer, employee or consultant of
the Company or any Subsidiary or Affiliate at the date of termination of the Optionee’s employment with the Company, or any of its
Subsidiaries or Affiliates or at any time during the twelve-month period immediately prior to the date of the termination of the Optionee’s
employment with the Company, its Subsidiaries or Affiliates (it being conclusively presumed by the parties so as to avoid any disputes
under this Section 7(d)(ii) that any such hiring within such twelve-month period is in violation of clause (i) above),
(iii) call on, solicit or provide any products or services to any customer, supplier, distributor, licensee, licensor, franchisee
or other business relation of the Company or any of its Subsidiaries or Affiliates (including any Person that was a customer, supplier
or other potential business relation of the Company, or any of its Subsidiaries or Affiliates at any time during the twelve-month period
immediately prior to such call, solicitation or service), or induce or attempt to induce such Person to cease doing business with the
Company or any of its Subsidiaries or Affiliates or (iv) in any way interfere with the relationship between any customer, supplier,
distributor, licensee, licensor, franchisee, or other business relation of the Company or any of its Subsidiaries or Affiliates (including,
without limitation, making any negative or disparaging statements or communications regarding the Company or any of its Subsidiaries or
Affiliates).

 

     

     

    

 

		(iii)	The Optionee understands that the foregoing restrictions may limit his ability to earn a livelihood in
a business similar to the business of the Company and its Subsidiaries or Affiliates, but he nevertheless believes that he has received
and will receive sufficient consideration and other benefits as an executive, a managerial or a key employee of the Company and as otherwise
provided hereunder to clearly justify such restrictions which, in any event (given his education, skills and ability), the Optionee does
not believe would prevent him from otherwise earning a living. Optionee acknowledges that the Company’s and its Subsidiaries’
and Affiliates’ businesses have been conducted or will soon be conducted throughout the Restricted Territories and that the geographic
restrictions and time periods, as well as all other restrictions and covenants in this Section 7(d) are reasonable and
necessary, and supported by good and valuable consideration, in order to protect a protectable interest of the Company’s, and its
Subsidiaries’ and Affiliates’ businesses, and that Optionee has reviewed the provisions of this Agreement with his legal counsel.
In addition, during the Noncompete Period, Optionee shall provide a copy of this Agreement, including, without limitation, Sections
7(a) through (d), to any prospective or subsequent employer or other person in connection with any employment or consulting
services to be performed by Optionee such that any such employer or other person is aware of and has a copy of the restrictions and other
obligations, terms and conditions set forth in such sections. Upon request from time to time by the Company, Optionee shall furnish the
Company with a true and complete certificate specifying compliance with this Section 7(d), and Optionee hereby authorizes
the Company at its reasonable discretion to contact any such prospective or subsequent employer or other person and inform them of this
Agreement or any other applicable and relevant policy or agreement between Optionee and the Company or its Affiliates or Subsidiaries
that may be in effect at the time that Optionee’s employment with the Company or its Affiliates or Subsidiaries ends.

 

		(iv)	If, at the time of enforcement of this Section 7(d), a court or arbiter shall hold that the
duration, scope or area restrictions stated herein are unreasonable under circumstances then existing, the parties agree that the maximum
duration, scope or area reasonable under such circumstances shall be substituted for the stated duration, scope or area and that the court
shall be allowed to revise the restrictions contained herein to cover the maximum period, scope and area permitted by law.

 

     

     

    

 

		(v)	In the event of the breach or a threatened breach by Optionee of any of the provisions of this Section 7(d),
the Company (and/or its Subsidiaries or Affiliates), in addition and supplementary to other rights and remedies existing in its (or their)
favor, shall be entitled to specific performance of this Section 7(d), including temporary, preliminary and/or permanent injunctive
or other equitable relief from a court of competent jurisdiction in order to stop and/or prevent any violations of the provisions hereof
(without posting a bond or other security), and shall also be entitled to require the Optionee to account for and pay over to the Company
(and/or its Subsidiaries or Affiliates) all compensation, profits, moneys, accruals, increments or other benefits derived from or received
as a result of any transactions constituting a breach of the covenants contained herein, and shall also be entitled to require Optionee
to repay any severance payments, gains on equity (including stock options) and other compensation and forfeit all equity (including stock
options) in any parent of the Company, paid or issued, as applicable, by the Company, or its Subsidiaries or their Affiliates. In addition,
in the event of an alleged breach or violation by Optionee of this Section 7(d), the restricted periods set forth in this
Section 7(d) shall be tolled until such breach or violation has been duly cured.

 

		8.	Definitions.

 

“Cause”
has the meaning set forth in any unexpired employment agreement between the Company and Optionee. In the absence of such agreement, “Cause”
means the Operating Board’s good faith determination that Optionee has (i) committed a felony or other crime involving moral
turpitude or the commission of any other act or omission involving theft, dishonesty, disloyalty or fraud with respect to the Company
or any of its Subsidiaries or any clients, customers, suppliers, vendors or employees of the Company or any of its Subsidiaries (or any
act that materially and negatively effects the business, integrity, character or reputation of the Company, any of its Subsidiaries or
any clients, customers, suppliers, vendors or employees of the Company or any of its Subsidiaries), (ii) reported to work intoxicated
or under the influence of illegal drugs, the use of illegal drugs (whether or not at the workplace) or other conduct causing the Company
or any of its Subsidiaries or Affiliates substantial public disgrace or disrepute or economic harm, (iii) substantially and repeatedly
failed to follow the policies, procedures and guidelines of the Company or any of its Subsidiaries (including with respect to sexual harassment
or inappropriate relationships with other employees) or substantial and repeated failure to perform duties as reasonably directed by the
Operating Board, in each case which is not cured to the Operating Board’s reasonable satisfaction within 30 days after written notice
thereof to Optionee, to the extent that such breach is capable of being cured, (iv) committed a breach of fiduciary duty, gross negligence
or willful misconduct with respect to the Company or any of its Subsidiaries or Affiliates, (v) engaged in any conduct that materially
and negatively affects Optionee’s own integrity, character or reputation (including Optionee’s reputation with any clients,
customers, suppliers, vendors or employees of the Company or any of its Subsidiaries) so as to cause Optionee to be unfit to act in any
capacity in which Optionee currently serves the Company or any of its Subsidiaries, (vi) committed chronic absenteeism (“chronic
absenteeism” shall be deemed to have occurred if Optionee has at least ten absences unrelated to disability or illness or scheduled
vacation in any ten-week period, or (vii) committed any other material breach of this Agreement which is not cured to the Operating
Board’s reasonable satisfaction within 15 days after written notice thereof to Optionee, to the extent that such breach is reasonably
capable of being cured. If Optionee’s employment ends for any reason other than discharge by the Company for Cause, but at a time
when the Company had Cause to terminate Optionee (or would have had Cause if it knew all relevant facts), Optionee’s termination

		10.	General Provisions.

 

		(a)	Severability and Judicial Modification. Whenever possible, each provision of this Agreement will
be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Agreement is held to be
invalid, illegal or unenforceable in any respect under any applicable law or rule in any jurisdiction, such invalidity, illegality
or unenforceability will not affect any other provision or any other jurisdiction, but this Agreement will be reformed, construed and
enforced in such jurisdiction as if such invalid, illegal or unenforceable provision had never been contained herein.

 

     

     

    

 

		(b)	Complete Agreement. This Agreement and those documents expressly referred to herein (including,
but not limited to, the Plan and the Operating Agreement) embody the complete agreement and understanding among the parties hereto and
supersede and preempt any prior understandings, agreements or representations by or among the parties hereto, written or oral, which may
have related to the subject matter hereof in any way; provided, however, that the restrictive covenants contained in this
Agreement shall be in addition to, and not in lieu of, and shall not in any way limit the enforceability of, any restrictive covenant
covering similar subject matter contained in any other agreement to which Optionee is a party.

 

		(c)	Counterparts. This Agreement may be executed in separate counterparts, each of which is deemed
to be an original and all of which taken together shall constitute one and the same agreement and shall become effective when one or more
counterparts have been signed by each of the parties hereto and delivered to the other. This Agreement and any amendments hereto, to the
extent signed and delivered by means of a facsimile machine or other electronic transmission (including transmission in portable document
format by electronic mail), shall be treated in all manner and respects and for all purposes as an original agreement and shall be considered
to have the same binding legal effect as if it were the original signed version thereof delivered in person.

 

		(d)	Successors and Assigns. Except as otherwise provided herein, this Agreement shall bind and inure
to the benefit of and be enforceable by Optionee, the Company, and their respective successors and assigns (including subsequent holders
of Participant Interests); provided that the rights and obligations of Optionee under this Agreement shall not be assignable except in
connection with a permitted transfer of Participant Interests under the Operating Agreement.

 

		(e)	Choice of Law. All other questions concerning the construction, validity, enforcement and interpretation
of this Agreement and the exhibits hereto shall be governed by the internal law, and not the law of conflicts, of the State of Delaware.

 

		(f)	Remedies. Each of the parties to this Agreement shall be entitled to enforce its rights under this
Agreement specifically, to recover damages and costs (including reasonable attorney’s fees) caused by any breach of any provision
of this Agreement and to exercise all other rights existing in its favor. The parties hereto agree and acknowledge that money damages
would not be an adequate remedy for any breach of the provisions of this Agreement and that the Company may in its sole discretion apply
to any court of law or equity of competent jurisdiction (without posting any bond or deposit, having to show that money damages will be
inadequate or impossible to determine or proving special damages or irreparable injury) for specific performance and/or other injunctive
relief in order to enforce or prevent any violations of the provisions of this Agreement. Optionee acknowledges, however, that no specification
in this Agreement of a specific legal or equitable remedy may be construed as a waiver of or prohibition against pursuing other legal
or equitable remedies in the event of a breach of this Agreement by Optionee. Optionee shall be liable for any breach by any Covered Entity
of this Agreement.

 

     

     

    

 

		(g)	No Strict Construction. The parties hereto have participated jointly in the negotiation and drafting
of this Agreement. In the event an ambiguity or question of intent or interpretation arises, this Agreement shall be construed as if drafted
jointly by the parties hereto, and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue of the authorship
of any of the provisions of this Agreement.

 

		(h)	Amendment and Waiver. The provisions of this Agreement may be amended and waived only with the
prior written consent of the Company (with approval by the Operating Board) and Optionee; provided, however, that the Company
(with approval by the Operating Board) may amend this Agreement without the consent of Optionee if such amendment does not materially
and adversely affect the Optionee in a manner that is disproportionate to the other Interest Holders.

 

		(i)	Business Days. If any time period for giving notice or taking action hereunder expires on a day
which is a Saturday, Sunday or legal holiday in the state in which the Company’s chief executive office is located, the time period
shall be automatically extended to the business day immediately following such Saturday, Sunday or holiday.

 

		(j)	Withholding. The Company shall be entitled, if necessary or desirable, to withhold from you from
any amounts due and payable by the Company to you (or secure payment from you in lieu of withholding) the amount of any withholding or
other tax due from the Company with respect to any Option Shares issuable under this Plan, and the Company may defer such issuance unless
indemnified by you to its satisfaction.

 

		(k)	Adjustments. In the event of a reorganization, recapitalization, Interest dividend or Interest
split, or combination or other change in the Interest, the Operating Board may, in order to prevent the dilution or enlargement of rights
under outstanding Options, make such adjustments in the number and type of Participant Interests authorized hereunder and the Exercise
Price specified herein as may be determined to be appropriate and equitable.
