	 	Re:	 Securities Subscription Agreement 

Ladies and Gentlemen: 
 We are pleased to accept
the offer Mason Industrial Sponsor, LLC (the “Subscriber” or “you”) has made to purchase 11,500,000 shares of Class B common stock (the “Shares”), $.0001 par value per share (the
“Class B Common Stock” together with all other classes of Company (as defined below) common stock, the “Common Stock”), up to 1,500,000 Shares of which are subject to complete or partial
forfeiture by you if the underwriters of the initial public offering (“IPO”) of Mason Industrial Technology, Inc., a Delaware corporation (the “Company”), do not fully exercise their over-allotment option (the
“Over-allotment Option”). The terms (this “Agreement”) on which the Company is willing to sell the Shares to the Subscriber, and the Company and the Subscriber’s agreements regarding such Shares, are as
follows: 
 ARTICLE 1 

PURCHASE OF SHARES 
 For
the sum of $25,000 (the “Purchase Price”), which the Company acknowledges receiving in cash, the Company hereby sells and issues the Shares to the Subscriber, and the Subscriber hereby purchases the Shares from the Company, subject
to the forfeiture provisions of Section 3 below, on the terms and subject to the conditions set forth in this Agreement. Concurrently with the Subscriber’s execution of this Agreement, the Company is delivering to the Subscriber a
certificate registered in the Subscriber’s name representing the Shares (the “Original Certificate”), receipt of which the Subscriber hereby acknowledges. 

ARTICLE 2 

REPRESENTATIONS, WARRANTIES AND AGREEMENTS. 

2.1 Subscriber’s Representations, Warranties and Agreements. To induce the Company to issue the Shares to the Subscriber, the
Subscriber hereby represents and warrants to the Company and agrees with the Company as follows: 
 2.1.1 No Government Recommendation or
Approval. The Subscriber understands that no federal or state agency has passed upon or made any recommendation or endorsement of the offering of the Shares. 

 2.1.2 No Conflicts. The execution, delivery and performance of this Agreement and the
consummation by the Subscriber of the transactions contemplated hereby do not violate, conflict with or constitute a default under (i) the formation and governing documents of the Subscriber, (ii) any agreement, indenture or instrument to
which the Subscriber is a party, (iii) any law, statute, rule or regulation to which the Subscriber is subject, or (iv) any agreement, order, judgment or decree to which the Subscriber is subject. 

2.1.3 Organization and Authority. The Subscriber is a Delaware limited liability company, validly existing and in good standing under
the laws of Delaware and possesses all requisite power and authority necessary to carry out the transactions contemplated by this Agreement. Upon execution and delivery by you, this Agreement will be a legal, valid and binding agreement of
Subscriber, enforceable against Subscriber in accordance with its terms, except as such enforceability may be limited by applicable bankruptcy, insolvency, fraudulent conveyance or similar laws affecting the enforcement of creditors’ rights
generally and subject to general principles of equity (regardless of whether enforcement is sought in a proceeding at law or in equity). 

2.1.4 Experience, Financial Capability and Suitability. Subscriber is: (i) sophisticated in financial matters and is able to
evaluate the risks and benefits of the investment in the Shares and (ii) able to bear the economic risk of its investment in the Shares for an indefinite period of time because the Shares have not been registered under the Securities Act (as
defined below) and therefore cannot be resold unless subsequently registered under the Securities Act or an exemption from such registration is available. Subscriber is capable of evaluating the merits and risks of its investment in the Company and
has the capacity to protect its own interests. Subscriber must bear the economic risk of this investment until the Shares are sold pursuant to: (x) an effective registration statement under the Securities Act or (y) an exemption from
registration available with respect to such sale. Subscriber is able to bear the economic risks of an investment in the Shares and to afford a complete loss of Subscriber’s investment in the Shares. 

2.1.5 Access to Information; Independent Investigation. Prior to the execution of this Agreement, the Subscriber has had the opportunity
to ask questions of and receive answers from representatives of the Company concerning an investment in the Company, as well as the finances, operations, business and prospects of the Company, and the opportunity to obtain additional information to
verify the accuracy of all information so obtained. In determining whether to make this investment, Subscriber has relied solely on Subscriber’s own knowledge and understanding of the Company and its business based upon Subscriber’s own
due diligence investigation and the information furnished pursuant to this paragraph. Subscriber understands that no person has been authorized to give any information or to make any representations which were not furnished pursuant to this
Section 2 and Subscriber has not relied on any other representations or information in making its investment decision, whether written or oral, relating to the Company, its operations or its prospects. 

  
 -2- 

 2.1.6 Accredited Investor. The Subscriber represents that it is an
“accredited investor” as such term is defined in Rule 501(a) of Regulation D under the Securities Act of 1933, as amended (the “Securities Act”) and acknowledges the sale contemplated hereby is being made in
reliance on a private placement exemption under federal and state law. 
 2.1.7 Investment Purposes. The Subscriber is purchasing the
Shares solely for investment purposes, for the Subscriber’s own account and not for the account or benefit of any other person, and not with a view towards the distribution or dissemination thereof that would result in a violation of the
Securities Act. The Subscriber did not enter into this Agreement as a result of any general solicitation or general advertising within the meaning of Rule 502 of Regulation D under the Securities Act. 

2.1.8 Restrictions on Transfer; Shell Company. The Subscriber understands the Shares are being offered in a transaction not involving a
public offering within the meaning of the Securities Act. Subscriber understands the Shares will be “restricted securities” as defined in Rule 144(a)(3) under the Securities Act and Subscriber understands that the certificate
representing the Shares will contain a legend in respect of such restrictions. If in the future the Subscriber decides to offer, resell, pledge or otherwise transfer the Shares, such Shares may be offered, resold, pledged or otherwise transferred
only in accordance with the provisions of Section 5 hereof. Subscriber agrees that if any transfer of its Shares or any interest therein is proposed to be made, as a condition precedent to any such transfer, Subscriber may be required to
deliver to the Company an opinion of counsel satisfactory to the Company. Absent registration or an exemption, the Subscriber agrees not to offer, resell, pledge or otherwise transfer the Shares. Subscriber further acknowledges that because the
Company is a shell company, Rule 144 may not be available to the Subscriber for the resale of the Shares until one year following consummation of the initial business combination of the Company, despite technical compliance with the certain
requirements of Rule 144 and the release or waiver of any contractual transfer restrictions. 
 2.1.9 No Governmental Consents. No
governmental, administrative or other third party consents or approvals are required, necessary or appropriate on the part of Subscriber in connection with the transactions contemplated by this Agreement. 

2.2 Company’s Representations, Warranties and Agreements. To induce the Subscriber to purchase the Shares, the Company hereby
represents and warrants to the Subscriber and agrees with the Subscriber as follows: 
 2.2.1 Organization and Corporate Power. The
Company is a Delaware corporation and is qualified to do business in every jurisdiction in which the failure to so qualify would reasonably be expected to have a material adverse effect on the financial condition, operating results or assets of the
Company. The Company possesses all requisite corporate power and authority necessary to carry out the transactions contemplated by this Agreement. 

2.2.2 No Conflicts. The execution, delivery and performance of this Agreement and the consummation by the Company of the transactions
contemplated hereby do not violate, conflict with or constitute a default under (i) the Certificate of Incorporation or Bylaws of the Company, (ii) any agreement, indenture or instrument to which the Company is a party, (iii) any law,
statute, rule or regulation to which the Company is subject, or (iv) any agreement, order, judgment or decree to which the Company is subject. 

  
 -3- 

 2.2.3 Title to Securities. Upon issuance in accordance with, and payment pursuant to,
the terms hereof, the Shares will be duly and validly issued, fully paid and nonassessable. Upon issuance in accordance with, and payment pursuant to, the terms hereof the Subscriber will have or receive good title to the Shares, free and clear of
all liens, claims and encumbrances of any kind, other than (a) transfer restrictions hereunder and other agreements to which the Shares may be subject which have been notified to the Subscriber in writing, (b) transfer restrictions under
federal and state securities laws, and (c) liens, claims or encumbrances imposed due to the actions of the Subscriber. 
 2.2.4 No
Adverse Actions. There are no actions, suits, investigations or proceedings pending, threatened against or affecting the Company which: (i) seek to restrain, enjoin, prevent the consummation of or otherwise affect the transactions
contemplated by this Agreement or (ii) question the validity or legality of any transactions or seek to recover damages or to obtain other relief in connection with any transactions. 

ARTICLE 3 
 FORFEITURE
OF SHARES. 
 3.1 Partial or No Exercise of the Over-allotment Option. In the event the Over-allotment Option granted to the
representative of the underwriters of the IPO is not exercised in full, the Subscriber acknowledges and agrees that it (and, if applicable, any transferee of Shares) shall forfeit any and all rights to such number of Shares (up to an aggregate of
1,500,000 Shares and pro rata based upon the percentage of the Over-allotment Option exercised) such that immediately following such forfeiture, the Subscriber (and any such transferees) will own an aggregate number of Shares (not including Shares
issuable upon exercise of any warrants or any Common Stock purchased by Subscriber in the IPO or in the aftermarket) equal to 20% of the issued and outstanding Common Stock immediately following the IPO. 

3.2 Termination of Rights as Stockholder. If any of the Shares are forfeited in accordance with this Section 3, then after such
time the Subscriber (or successor in interest), shall no longer have any rights as a holder of such Shares, and the Company shall take such action as is appropriate to cancel such Shares. 

3.3 Share Certificates. In the event an adjustment to the Original Certificate is required pursuant to this Section 3, then the
Subscriber shall return such Original Certificate to the Company or its designated agent as soon as practicable upon its receipt of notice from the Company advising Subscriber of such adjustment, following which a new certificate (the “New
Certificate”) shall be issued in such amount representing the adjusted number of Shares held by the Subscriber. The New Certificate shall be returned to the Subscriber as soon as practicable. 

  
 -4- 

 ARTICLE 4 

WAIVER OF LIQUIDATION DISTRIBUTIONS; REDEMPTION RIGHTS 

In connection with the Shares purchased pursuant to this Agreement, the Subscriber hereby waives any and all right, title, interest or claim
of any kind in or to any distributions by the Company from the trust account which will be established for the benefit of the Company’s public stockholders and into which substantially all of the proceeds of the IPO will be deposited (the
“Trust Account”), in the event of a liquidation of the Company upon the Company’s failure to timely complete an initial business combination. For purposes of clarity, in the event the Subscriber purchases Common Stock in the
IPO or in the aftermarket, any additional Common Stock so purchased shall be eligible to receive any liquidating distributions by the Company. However, in no event will the Subscriber have the right to redeem any Shares into funds held in the Trust
Account upon the successful completion of an initial business combination. 
 ARTICLE 5 

RESTRICTIONS ON TRANSFER 

5.1 Securities Law Restrictions. In addition to any restrictions to be contained in that certain letter agreement (commonly known as an
“Insider Letter”) to be dated as of the closing of the IPO by and between Subscriber and the Company, Subscriber agrees not to sell, transfer, pledge, hypothecate or otherwise dispose of all or any part of the Shares unless, prior
thereto (a) a registration statement on the appropriate form under the Securities Act and applicable state securities laws with respect to the Shares proposed to be transferred shall then be effective or (b) the Company has received an
opinion from counsel reasonably satisfactory to the Company, that such registration is not required because such transaction is exempt from registration under the Securities Act and the rules promulgated by the Securities and Exchange Commission
thereunder and with all applicable state securities laws. 
 5.2 Lock-up. Subscriber
acknowledges that the Shares will be subject to lock-up provisions contained in the Insider Letter. 

5.3 Restrictive Legends. All certificates representing the Shares shall have endorsed thereon legends substantially as follows: 

“THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR ANY STATE SECURITIES LAWS AND
NEITHER THE SECURITIES NOR ANY INTEREST THEREIN MAY BE OFFERED, SOLD, TRANSFERRED, PLEDGED OR OTHERWISE DISPOSED OF EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER SUCH ACT OR SUCH LAWS OR AN EXEMPTION FROM REGISTRATION UNDER SUCH ACT
AND SUCH LAWS WHICH, IN THE OPINION OF COUNSEL, IS AVAILABLE.” 

  
 -5- 

 “THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO LOCKUP PROVISIONS AND
MAY NOT BE OFFERED, SOLD, TRANSFERRED, PLEDGED OR OTHERWISE DISPOSED DURING THE TERM OF THE LOCKUP PERIOD.” 
 5.4 Additional Shares
or Substituted Securities. In the event of the declaration of a stock dividend, the declaration of a special dividend payable in a form other than Common Stock, a spin-off, a stock split, an adjustment in
conversion ratio, a recapitalization or a similar transaction affecting the Company’s outstanding Common Stock without receipt of consideration, any new, substituted or additional securities or other property which are by reason of such
transaction distributed with respect to any Shares subject to this Section 5 or into which such Shares thereby become convertible shall immediately be subject to this Section 5 and Section 3. Appropriate adjustments to reflect the
distribution of such securities or property shall be made to the number or class of Shares subject to this Section 5 and Section 3. 

5.5 Registration Rights. The Subscriber acknowledges that the Shares are being purchased pursuant to an exemption from the registration
requirements of the Securities Act and will become freely tradable only after certain conditions are met or they are registered pursuant to a Registration Rights Agreement to be entered into with the Company prior to the closing of the IPO. 

ARTICLE 6 
 OTHER
AGREEMENTS 
 6.1 Further Assurances. The Subscriber agrees to execute such further instruments and to take such further action
as may reasonably be necessary to carry out the intent of this Agreement. 
 6.2 Notices. All notices, statements or other documents
which are required or contemplated by this Agreement shall be in writing and delivered: (i) personally or sent by first class registered or certified mail, overnight courier service or facsimile or electronic transmission to the address

6.3 Entire Agreement. This Agreement, together with that certain Insider Letter to be entered into between Subscriber and the Company,
substantially in the form to be filed as an exhibit to the Registration Statement, embodies the entire agreement and understanding between the Subscriber and the Company with respect to the subject matter hereof and supersedes all prior oral or
written agreements and understandings relating to the subject matter hereof. No statement, representation, warranty, covenant or agreement of any kind not expressly set forth in this Agreement shall affect, or be used to interpret, change or
restrict, the express terms and provisions of this Agreement. 

  
 -6- 

 6.4 Modifications and Amendments. The terms and provisions of this Agreement may be
modified or amended only by written agreement executed by all parties hereto. 
 6.5 Waivers and Consents. The terms and provisions of
this Agreement may be waived, or consent for the departure therefrom granted, only by written document executed by the party entitled to the benefits of such terms or provisions. No such waiver or consent shall be deemed to be or shall constitute a
waiver or consent with respect to any other terms or provisions of this Agreement, whether or not similar. Each such waiver or consent shall be effective only in the specific instance and for the purpose for which it was given, and shall not
constitute a continuing waiver or consent. 
 6.6 Assignment. The rights and obligations under this Agreement may not be assigned by
either party hereto without the prior written consent of the other party. 
 6.7 Benefit. All statements, representations, warranties,
covenants and agreements in this Agreement shall be binding on the parties hereto and shall inure to the benefit of the respective successors and permitted assigns of each party hereto. Nothing in this Agreement shall be construed to create any
rights or obligations except among the parties hereto, and no person or entity shall be regarded as a third-party beneficiary of this Agreement. 

6.8 Governing Law. This Agreement and the rights and obligations of the parties hereunder shall be construed in accordance with and
governed by the laws of New York applicable to contracts wholly performed within the borders of such state, without giving effect to the conflict of law principles thereof. The parties hereto irrevocably submit to the exclusive jurisdiction of any
federal court sitting in the Southern District of New York or any state court located in New York County, State of New York, over any suit, action or proceeding arising out of or relating to this Agreement. To the fullest extent they may effectively
do so under applicable law, the parties hereto irrevocably waive and agree not to assert, by way of motion, as a defense or otherwise, any claim that they are not subject to the jurisdiction of any such court, any objection that they may now or
hereafter have to the laying of the venue of any such suit, action or proceeding brought in any such court and any claim that any such suit, action or proceeding brought in any such court has been brought in an inconvenient forum. 

6.9 Severability. In the event that any court of competent jurisdiction shall determine that any provision, or any portion thereof,
contained in this Agreement shall be unreasonable or unenforceable in any respect, then such provision shall be deemed limited to the extent that such court deems it reasonable and enforceable, and as so limited shall remain in full force and
effect. In the event that such court shall deem any such provision, or portion thereof, wholly unenforceable, the remaining provisions of this Agreement shall nevertheless remain in full force and effect. 

  
 -7- 

 6.10 No Waiver of Rights, Powers and Remedies. No failure or delay by a party hereto
in exercising any right, power or remedy under this Agreement, and no course of dealing between the parties hereto, shall operate as a waiver of any such right, power or remedy of such party. No single or partial exercise of any right, power or
remedy under this Agreement by a party hereto, nor any abandonment or discontinuance of steps to enforce any such right, power or remedy, shall preclude such party from any other or further exercise thereof or the exercise of any other right, power
or remedy hereunder. The election of any remedy by a party hereto shall not constitute a waiver of the right of such party to pursue other available remedies. No notice to or demand on a party not expressly required under this Agreement shall
entitle the party receiving such notice or demand to any other or further notice or demand in similar or other circumstances or constitute a waiver of the rights of the party giving such notice or demand to any other or further action in any
circumstances without such notice or demand. 
 6.11 Survival of Representations and Warranties. All representations and warranties
made by the parties hereto in this Agreement or in any other agreement, certificate or instrument provided for or contemplated hereby, shall survive the execution and delivery hereof and any investigations made by or on behalf of the parties. 

6.12 No Broker or Finder. Each of the parties hereto represents and warrants to the other that no broker, finder or other financial
consultant has acted on its behalf in connection with this Agreement or the transactions contemplated hereby in such a way as to create any liability on the other. Each of the parties hereto agrees to indemnify and hold the other harmless from any
claim or demand for commission or other compensation by any broker, finder, financial consultant or similar agent claiming to have been employed by or on behalf of such party and to bear the cost of legal expenses incurred in defending against any
such claim. 
 6.13 Headings and Captions. The headings and captions of the various sections of this Agreement are for convenience of
reference only and shall in no way modify or affect the meaning or construction of any of the terms or provisions hereof. 
 6.14
Counterparts. This Agreement may be executed in one or more counterparts, all of which when taken together shall be considered one and the same agreement and shall become effective when counterparts have been signed by each party and
delivered to the other party, it being understood that both parties need not sign the same counterpart. In the event that any signature is delivered by facsimile transmission or any other form of electronic delivery, such signature shall create a
valid and binding obligation of the party executing (or on whose behalf such signature is executed) with the same force and effect as if such signature page were an original thereof. 

6.15 Construction. The words “include,” “includes,” and “including” will be deemed to
be followed by “without limitation.” Pronouns in masculine, feminine, and neuter genders will be construed to include any other gender, and words in the singular form will be construed to include the plural and vice versa, unless the
context otherwise requires. The words “this Agreement,” “herein,” “hereof,” “hereby,” “hereunder,” and words of similar import refer to this Agreement as a whole
and not to any particular section unless expressly so limited. The parties hereto intend that each representation, warranty, and covenant contained herein will have independent significance. If any party hereto has breached any representation,
warranty, or covenant contained herein in any respect, the fact that there exists another representation, warranty or covenant relating to the same subject matter (regardless of the relative levels of specificity) which such party hereto has not
breached will not detract from or mitigate the fact that such party hereto is in breach of the first representation, warranty, or covenant. 

  
 -8- 

 6.16 Mutual Drafting. This Agreement is the joint product of the Subscriber and the
Company and each provision hereof has been subject to the mutual consultation, negotiation and agreement of such parties and shall not be construed for or against any party hereto. 

ARTICLE 7 
 VOTING AND
REDEMPTION OF SHARES 
 The Subscriber agrees to vote the Shares in favor of an initial business combination that the Company negotiates
and submits for approval to the Company’s stockholders and shall not seek redemption with respect to such Shares. Additionally, the Subscriber agrees not to redeem any Shares in connection with a redemption or tender offer presented to the
Company’s stockholders in connection with an initial business combination negotiated by the Company. 
 ARTICLE 8 

INDEMNIFICATION 
 Each
party shall indemnify (such party, the “Indemnifying Party”) the other party (such party, the “Indemnified Party”) and its respective officers, employees, and controlling persons to the fullest extent permitted by
law from and against any and all losses, damages, expenses (including reasonable attorneys’ fees and expenses) or other liabilities resulting from or arising out of such party’s breach of any representation, warranty, covenant or agreement
in this Agreement. The foregoing indemnification rights apply so long as the action or failure to act by the Indemnified Party does not constitute fraud, bad faith, willful misconduct or gross negligence. Notwithstanding any of the foregoing to the
contrary, indemnification protections will not be construed so as to relieve (or attempt to relieve) any Indemnified Party of any liability (including liability under federal securities laws which, under certain circumstances, impose liability even
on persons that act in good faith), to the extent (but only to the extent) that such liability may not be waived, modified or limited under applicable law, but will only be construed so as to effectuate the indemnification protections to the fullest
extent permitted by law.

 Exhibit 10.7 

INDEMNITY AGREEMENT 
 THIS
INDEMNITY AGREEMENT (this “Agreement”) is made as of [ ], by and between Mason Industrial Technology, Inc., a Delaware corporation (the “Company”), and [ ]
(“Indemnitee”). 
 RECITALS 

WHEREAS, the Board of Directors of the Company (the “Board”) has determined that it is reasonable, prudent and
necessary for the Company contractually to obligate itself to indemnify, hold harmless, exonerate and to advance expenses on behalf of, persons who serve the Company to the fullest extent permitted by applicable law; 

WHEREAS, this Agreement is a supplement to and in furtherance of the Amended and Restated Certificate of Incorporation (the
“Charter”) and the Bylaws (the “Bylaws”) of the Company and any resolutions adopted pursuant thereto, and shall not be deemed a substitute therefor, nor to diminish or abrogate any rights of Indemnitee
thereunder; 
 WHEREAS, Indemnitee may not be willing to serve as an officer or director, advisor or in another capacity without adequate
protection, and the Company desires Indemnitee to serve in such capacity. Indemnitee is willing to serve, continue to serve and to take on additional service for or on behalf of the Company on the condition that Indemnitee be so indemnified; and

 NOW, THEREFORE, in consideration of the premises and the covenants contained herein and subject to the provisions of the letter agreement
dated as of [        ], the Company and Indemnitee do hereby covenant and agree as follows: 

TERMS AND CONDITIONS 

1. SERVICES TO THE COMPANY. In consideration of the Company’s covenants and obligations hereunder, Indemnitee will serve or
continue to serve as an officer, director, advisor, key employee or any other capacity of the Company, as applicable, for so long as Indemnitee is duly elected or appointed or retained or until Indemnitee tenders Indemnitee’s resignation or
until Indemnitee is removed. The foregoing notwithstanding, this Agreement shall continue in full force and effect after Indemnitee has ceased to serve as a director, officer, advisor, key employee or in any other capacity of the Company, as
provided in Section 17. This Agreement, however, shall not impose any obligation on Indemnitee or the Company to continue Indemnitee’s service to the Company beyond any period otherwise required by law or by other agreements or commitments
of the parties, if any. 

 2. DEFINITIONS. As used in this Agreement: 

(a) References to “agent” shall mean any person who is or was a director, officer or employee of the Company or a
subsidiary of the Company or other person authorized by the Company to act for the Company, to include such person serving in such capacity as a director, officer, employee, fiduciary or other official of another corporation, partnership, limited
liability company, joint venture, trust or other enterprise at the request of, for the convenience of, or to represent the interests of the Company or a subsidiary of the Company. 

(b) The terms “Beneficial Owner” and “Beneficial Ownership” shall have the meanings set forth

outstanding securities entitled to vote generally in the election of directors, unless (1) the change in the relative Beneficial Ownership of the Company’s securities by any Person results solely from a reduction in the aggregate number of
outstanding shares of securities entitled to vote generally in the election of directors, or (2) such acquisition was approved in advance by the Continuing Directors (as defined below) and such acquisition would not constitute a Change in
Control under part (iii) of this definition; 
 (ii) Change in Board of Directors. Individuals who, as of the
date hereof, constitute the Board, and any new director whose election by the Board or nomination for election by the Company’s stockholders was approved by a vote of at least two thirds of the directors then still in office who were directors

voting power of the then outstanding securities of the Company entitled to vote generally in the election of directors resulting from such Business Combination (including, without limitation, a corporation which as a result of such transaction owns
the Company or all or substantially all of the Company’s assets either directly or through one or more Subsidiaries (as defined below)) in substantially the same proportions as their ownership immediately prior to such Business Combination, of
the securities entitled to vote generally in the election of directors; (2) other than an affiliate of MIT Sponsor, no Person (excluding any corporation resulting from such Business Combination) is the Beneficial Owner, directly or indirectly,
of 15% or more of the combined voting power of the then outstanding

least a majority of the Board of Directors of the corporation resulting from such Business Combination were Continuing Directors at the time of the execution of the initial agreement, or of the action of the Board of Directors, providing for such
Business Combination; 
 (iv) Liquidation. The approval by the stockholders of the Company of a complete liquidation
of the Company or an agreement or series of agreements for the sale or disposition by the Company of all or substantially all of the Company’s assets, other than factoring the Company’s current receivables or escrows due (or, if such
stockholder approval is not required, the decision by the Board to proceed with such a liquidation, sale, or disposition in one transaction or a series of related transactions); or 

(v) Other Events. There occurs any other event of a nature that would be required to be reported in response to Item

plan; references to “serving at the request of the Company” shall include any service as a director, officer, employee, agent or fiduciary of the Company which imposes duties on, or involves services by, such director,
officer, employee, agent or fiduciary with respect to an employee benefit plan, its participants or beneficiaries; and if Indemnitee acted in good faith and in a manner Indemnitee reasonably believed to be in the best interests of the participants
and beneficiaries of an employee benefit plan, Indemnitee shall be deemed to have acted in a manner “not opposed to the best interests of the Company” as referred to in this Agreement. 

(k) “Independent Counsel” shall mean a law firm or a member of a law firm with significant experience in matters of
corporation law and that neither presently is, nor in the past five years has been, retained to represent: (i) the Company or Indemnitee in any matter material to either such party (other than with respect to matters concerning Indemnitee under
this Agreement, or of other indemnitees under similar indemnification agreements); or (ii) any other party to the Proceeding (as defined below) giving rise to a claim for indemnification hereunder. Notwithstanding the foregoing, the term
“Independent Counsel” shall not include any person who, under the applicable standards of professional conduct then prevailing, would have a conflict of interest in representing either the Company or Indemnitee in an action to determine
Indemnitee’s rights under this Agreement. 
 (l) The term “Person” shall have the meaning as set forth in
Sections 13(d) and 14(d) of the Exchange Act as in effect on the date hereof; provided, however, that “Person” shall exclude: (i) the Company; (ii) any Subsidiaries (as defined below) of the Company; (iii) any employment
benefit plan of the Company or of a Subsidiary (as defined below) of the Company or of any corporation owned, directly or indirectly, by the stockholders of the Company in substantially the same proportions as their ownership of stock of the
Company; and (iv) any trustee or other fiduciary holding securities under an employee benefit plan of the Company or of a Subsidiary (as defined below) of the Company or of a corporation owned directly or indirectly by the stockholders of the
Company in substantially the same proportions as their ownership of stock of the Company. 
 (m) The term
“Proceeding” shall include any threatened, pending or completed action, suit, arbitration, mediation, alternate dispute resolution mechanism, investigation, inquiry, administrative hearing or any other actual, threatened or
completed proceeding, whether brought in the right of the Company or otherwise and whether of a civil (including intentional or unintentional tort claims), criminal, administrative or investigative or related nature, in which Indemnitee was, is,
will or might be involved as a party or otherwise by reason of the fact that 

  
 -4- 

 
Indemnitee is or was a director or officer of the Company, by reason of any action (or failure to act) taken by Indemnitee or of any action (or failure to act) on Indemnitee’s part while
acting as a director or officer of the Company, or by reason of the fact that Indemnitee is or was serving at the request of the Company as a director, officer, trustee, general partner, managing member, fiduciary, employee or agent of any other
Enterprise, in each case whether or not serving in such capacity at the time any liability or expense is incurred for which indemnification, reimbursement, or advancement of expenses can be provided under this Agreement. 

(n) The term “Subsidiary,” with respect to any Person, shall mean any corporation, limited liability company,
partnership, joint venture, trust or other entity of which a majority of the voting power of the voting equity securities or equity interest is owned, directly or indirectly, by that Person. 

3. INDEMNITY IN THIRD-PARTY PROCEEDINGS. To the fullest extent permitted by applicable law, the Company shall indemnify, hold harmless
and exonerate Indemnitee in accordance with the provisions of this Section 3 if Indemnitee was, is, or is threatened to be made, a party to or a participant (as a witness, deponent or otherwise) in any Proceeding, other than a Proceeding by or
in the right of the Company to procure a judgment in its favor by reason of Indemnitee’s Corporate Status. Pursuant to this Section 3, Indemnitee shall be indemnified, held harmless and exonerated against all Expenses, judgments,
liabilities, fines, penalties and amounts paid in settlement (including all interest, assessments and other charges paid or payable in connection with or in respect of such Expenses, judgments, fines, penalties and amounts paid in settlement)
actually, and reasonably incurred by Indemnitee or on Indemnitee’s behalf in connection with such Proceeding or any claim, issue or matter therein, if Indemnitee acted in good faith and in a manner he reasonably believed to be in or not opposed
to the best interests of the Company and, in the case of a criminal Proceeding, had no reasonable cause to believe that Indemnitee’s conduct was unlawful. 

4. INDEMNITY IN PROCEEDINGS BY OR IN THE RIGHT OF THE COMPANY. To the fullest extent permitted by applicable law, the Company shall
indemnify, hold harmless and exonerate Indemnitee in accordance with the provisions of this Section 4 if Indemnitee was, is, or is threatened to be made, a party to or a participant (as a witness, deponent or otherwise) in any Proceeding by or
in the right of the Company to procure a judgment in its favor by reason of Indemnitee’s Corporate Status. Pursuant to this Section 4, Indemnitee shall be indemnified, held harmless and exonerated against all Expenses actually and
reasonably incurred by Indemnitee or on Indemnitee’s behalf in connection with such Proceeding or any claim, issue or matter therein, if Indemnitee acted in good faith and in a manner Indemnitee reasonably believed to be in or not opposed to
the best interests of the Company. No indemnification, hold harmless or exoneration for Expenses shall be made under this Section 4 in respect of any claim, issue or matter as to which Indemnitee shall have been finally adjudged by a court to
be liable to the Company, unless and only to the extent that any court in which the Proceeding was brought or the Delaware Court shall determine upon application that, despite the adjudication of liability but in view of all the circumstances of the
case, Indemnitee is fairly and reasonably entitled to indemnification, to be held harmless or to exoneration. 

  
 -5- 

 5. INDEMNIFICATION FOR EXPENSES OF A PARTY WHO IS WHOLLY OR PARTLY SUCCESSFUL.
Notwithstanding any other provisions of this Agreement except for Section 27, to the extent that Indemnitee was or is, by reason of Indemnitee’s Corporate Status, a party to (or a participant in) and is successful, on the merits or
otherwise, in any Proceeding or in defense of any claim, issue or matter therein, in whole or in part, the Company shall, to the fullest extent permitted by applicable law, indemnify, hold harmless and exonerate Indemnitee against all Expenses
actually and reasonably incurred by Indemnitee in connection therewith. If Indemnitee is not wholly successful in such Proceeding but is successful, on the merits or otherwise, as to one or more but less than all claims, issues or matters in such
Proceeding, the Company shall, to the fullest extent permitted by applicable law, indemnify, hold harmless and exonerate Indemnitee against all Expenses actually and reasonably incurred by Indemnitee or on Indemnitee’s behalf in connection with
each successfully resolved claim, issue or matter. If Indemnitee is not wholly successful in such Proceeding, the Company also shall, to the fullest extent permitted by applicable law, indemnify, hold harmless and exonerate Indemnitee against all
Expenses reasonably incurred in connection with a claim, issue or matter related to any claim, issue, or matter on which Indemnitee was successful. For purposes of this Section and without limitation, the termination of any claim, issue or matter in
such a Proceeding by dismissal, with or without prejudice, shall be deemed to be a successful result as to such claim, issue or matter. 
 6.
INDEMNIFICATION FOR EXPENSES OF A WITNESS. Notwithstanding any other provision of this Agreement except for Section 27, to the extent that Indemnitee is, by reason of Indemnitee’s Corporate Status, a witness or deponent in any
Proceeding to which Indemnitee was or is not a party or threatened to be made a party, Indemnitee shall, to the fullest extent permitted by applicable law, be indemnified, held harmless and exonerated against all Expenses actually and reasonably
incurred by Indemnitee or on Indemnitee’s behalf in connection therewith. 
 7. ADDITIONAL INDEMNIFICATION, HOLD HARMLESS AND
EXONERATION RIGHTS. 
 (a) Notwithstanding any limitation in Sections 3, 4, or 5, except for Section 27, the Company shall, to the
fullest extent permitted by applicable law, indemnify, hold harmless and exonerate Indemnitee if Indemnitee is a party to or threatened to be made a party to any Proceeding (including a Proceeding by or in the right of the Company to procure a
judgment in its favor) against all Expenses, judgments, fines, penalties and amounts paid in settlement (including all interest, assessments and other charges paid or payable in connection with or in respect of such Expenses, judgments, fines,
penalties and amounts paid in settlement) actually and reasonably incurred by Indemnitee in connection with the Proceeding. No indemnification, hold harmless or exoneration rights shall be available under this Section 7(a) on account of
Indemnitee’s conduct which constitutes a breach of Indemnitee’s duty of loyalty to the Company or its stockholders or is an act or omission not in good faith or which involves intentional misconduct or a knowing violation of the law. 

(b) Notwithstanding any limitation in Sections 3, 4, 5 or 7(a), except for Section 27, the Company shall, to the fullest extent permitted
by applicable law, indemnify, hold harmless and exonerate Indemnitee if Indemnitee is a party to or threatened to be made a party to any Proceeding (including a Proceeding by or in the right of the Company to procure a judgment in its favor) against
all Expenses, judgments, fines, penalties and amounts paid in settlement (including all interest, assessments and other charges paid or payable in connection with or in respect of such Expenses, judgments, fines, penalties and amounts paid in
settlement) actually and reasonably incurred by Indemnitee in connection with the Proceeding. 

  
 -6- 

 8. CONTRIBUTION IN THE EVENT OF JOINT LIABILITY. 

(a) To the fullest extent permissible under applicable law, if the indemnification, hold harmless and/or exoneration rights provided for in
this Agreement are unavailable to Indemnitee in whole or in part for any reason whatsoever, the Company, in lieu of indemnifying, holding harmless or exonerating Indemnitee, shall pay, in the first instance, the entire amount incurred by Indemnitee,
whether for judgments, liabilities, fines, penalties, amounts paid or to be paid in settlement and/or for Expenses, in connection with any Proceeding without requiring Indemnitee to contribute to such payment, and the Company hereby waives and
relinquishes any right of contribution it may have at any time against Indemnitee. 
 (b) The Company shall not enter into any settlement of
any Proceeding in which the Company is jointly liable with Indemnitee (or would be if joined in such Proceeding) unless such settlement provides for a full and final release of all claims asserted against Indemnitee. 

(c) The Company hereby agrees to fully indemnify, hold harmless and exonerate Indemnitee from any claims for contribution which may be brought
by officers, directors or employees of the Company other than Indemnitee who may be jointly liable with Indemnitee. 
 9. EXCLUSIONS.
Notwithstanding any provision in this Agreement, the Company shall not be obligated under this Agreement to make any indemnification, advance expenses, hold harmless or exoneration payment in connection with any claim made against Indemnitee: 

(a) for which payment has actually been received by or on behalf of Indemnitee under any insurance policy or other indemnity or advancement
provision, except with respect to any excess beyond the amount actually received under any insurance policy, contract, agreement, other indemnity or advancement provision or otherwise; 

(b) for an accounting of profits made from the purchase and sale (or sale and purchase) by Indemnitee of securities of the Company within the
meaning of Section 16(b) of the Exchange Act (or any successor rule) or similar provisions of state statutory law or common law; or 

(c) except as otherwise provided in Sections 14(f)-(g) hereof, prior to a Change in Control, in connection with any Proceeding (or any part of
any Proceeding) initiated by Indemnitee, including any Proceeding (or any part of any Proceeding) initiated by Indemnitee against the Company or its directors, officers, employees or other indemnitees, unless (i) the Board authorized the
Proceeding (or any part of any Proceeding) prior to its initiation or (ii) the Company provides the indemnification, hold harmless or exoneration payment, in its sole discretion, pursuant to the powers vested in the Company under applicable
law. Indemnitee shall seek payments or Advances from the Company only to the extent that such payments or Advances are unavailable from any insurance policy of the Company covering Indemnitee. 

  
 -7- 

 10. ADVANCES OF EXPENSES; DEFENSE OF CLAIM. 

(a) Notwithstanding any provision of this Agreement to the contrary, except for Section 27, and to the fullest extent not prohibited by
applicable law, the Company shall pay the Expenses incurred by Indemnitee (or reasonably expected by Indemnitee to be incurred by Indemnitee within three months) in connection with any Proceeding within ten (10) days after the receipt by the
Company of a statement or statements requesting such advances from time to time, prior to the final disposition of any Proceeding. Advances shall, to the fullest extent permitted by law, be unsecured and interest free. Advances shall, to the fullest
extent permitted by law, be made without regard to Indemnitee’s ability to repay the Expenses and without regard to Indemnitee’s ultimate entitlement to be indemnified, held harmless or exonerated under the other provisions of this
Agreement. Advances shall include any and all reasonable Expenses incurred pursuing a Proceeding to enforce this right of advancement, including Expenses incurred preparing and forwarding statements to the Company to support the advances claimed. To
the fullest extent required by applicable law, such payments of Expenses in advance of the final disposition of the Proceeding shall be made only upon the Company’s receipt of an undertaking, by or on behalf of Indemnitee, to repay the advanced
amounts to the extent that it is ultimately determined that Indemnitee is not entitled to be indemnified, held harmless or exonerated by the Company under the provisions of this Agreement, the Charter, the Bylaws of the Company, applicable law or
otherwise. This Section 10(a) shall not apply to any claim made by Indemnitee for which an indemnification, hold harmless or exoneration payment is excluded pursuant to Section 9. 

(b) The Company will be entitled to participate in the Proceeding at its own expense. 

(c) The Company shall not settle any action, claim or Proceeding (in whole or in part) which would impose any Expense, judgment, fine, penalty
or limitation on Indemnitee without Indemnitee’s prior written consent. 
 11. PROCEDURE FOR NOTIFICATION AND APPLICATION FOR
INDEMNIFICATION. 
 (a) Indemnitee agrees to notify promptly the Company in writing upon being served with any summons, citation,
subpoena, complaint, indictment, information or other document relating to any Proceeding, claim, issue or matter therein which may be subject to indemnification, hold harmless or exoneration rights, or advancement of Expenses covered hereunder. The
failure of Indemnitee to so notify the Company shall not relieve the Company of any obligation which it may have to Indemnitee under this Agreement, or otherwise. 

(b) Indemnitee may deliver to the Company a written application to indemnify, hold harmless or exonerate Indemnitee in accordance with this
Agreement. Such application(s) may be delivered from time to time and at such time(s) as Indemnitee deems appropriate in his sole discretion. Following such a written application for indemnification by Indemnitee, Indemnitee’s entitlement to
indemnification shall be determined according to Section 12(a) of this Agreement. 

  
 -8- 

 12. PROCEDURE UPON APPLICATION FOR INDEMNIFICATION. 

(a) A determination, if required by applicable law, with respect to Indemnitee’s entitlement to indemnification shall be made in the
specific case by one of the following methods, which shall be at the election of Indemnitee: (i) by a majority vote of the Disinterested Directors, even though less than a quorum of the Board, (ii) by a committee of such directors
designated by majority vote of such directors, (iii) if there are no Disinterested Directors or if such directors so direct, by Independent Counsel in a written opinion to the Board, a copy of which shall be delivered to Indemnitee, or
(iv) by vote of the stockholders. The Company promptly will advise Indemnitee in writing with respect to any determination that Indemnitee is or is not entitled to indemnification, including a description of any reason or basis for which
indemnification has been denied. If it is so determined that Indemnitee is entitled to indemnification, payment to Indemnitee shall be made within ten (10) days after such determination. Indemnitee shall reasonably cooperate with the person,
persons or entity making such determination with respect to Indemnitee’s entitlement to indemnification, including providing to such person, persons or entity upon reasonable advance request any documentation or information which is not
privileged or otherwise protected from disclosure and which is reasonably available to Indemnitee and reasonably necessary to such determination. Any costs or Expenses (including reasonable attorneys’ fees and disbursements) incurred by
Indemnitee in so cooperating with the person, persons or entity making such determination shall be borne by the Company (irrespective of the determination as to Indemnitee’s entitlement to indemnification) and the Company hereby agrees to
indemnify and to hold Indemnitee harmless therefrom. 
 (b) In the event the determination of entitlement to indemnification is to be made by
Independent Counsel pursuant to Section 12(a) hereof, the Independent Counsel shall be selected as provided in this Section 12(b). The Independent Counsel shall be selected by Indemnitee (unless Indemnitee shall request that such selection
be made by the Board), and Indemnitee shall give written notice to the Company advising it of the identity of the Independent Counsel so selected and certifying that the Independent Counsel so selected meets the requirements of “Independent
Counsel” as defined in Section 2 of this Agreement. If the Independent Counsel is selected by the Board, the Company shall give written notice to Indemnitee advising Indemnitee of the identity of the Independent Counsel so selected and
certifying that the Independent Counsel so selected meets the requirements of “Independent Counsel” as defined in Section 2 of this Agreement. In either event, Indemnitee or the Company, as the case may be, may, within ten
(10) days after such written notice of selection shall have been received, deliver to the Company or to Indemnitee, as the case may be, a written objection to such selection; provided, however, that such objection may be asserted only on the
ground that the Independent Counsel so selected does not meet the requirements of “Independent Counsel” as defined in Section 2 of this Agreement, and the objection shall set forth with particularity the factual basis of such
assertion. Absent a proper and timely objection, the person so selected shall act as Independent Counsel. If such written objection is so made and substantiated, the Independent Counsel so selected may not serve as Independent Counsel unless and
until such objection is withdrawn or a court of competent jurisdiction has determined that such objection is without merit. If, within twenty (20) days after submission by Indemnitee of a written request for indemnification pursuant to
Section 11(b) hereof, no Independent Counsel shall have been selected and not objected to, either the Company or Indemnitee may petition the Delaware Court for resolution of any objection which shall have been made by the Company or Indemnitee
to the other’s selection of Independent Counsel and/or 

  
 -9- 

 
for the appointment as Independent Counsel of a person selected by the Delaware Court, and the person with respect to whom all objections are so resolved or the person so appointed shall act as
Independent Counsel under Section 12(a) hereof. Upon the due commencement of any judicial proceeding or arbitration pursuant to Section 14(a) of this Agreement, Independent Counsel shall be discharged and relieved of any further
responsibility in such capacity (subject to the applicable standards of professional conduct then prevailing). 
 (c) The Company agrees to
pay the reasonable fees and expenses of Independent Counsel and to fully indemnify and hold harmless such Independent Counsel against any and all Expenses, claims, liabilities and damages arising out of or relating to this Agreement or its
engagement pursuant hereto. 
 13. PRESUMPTIONS AND EFFECT OF CERTAIN PROCEEDINGS. 

(a) In making a determination with respect to entitlement to indemnification hereunder, the person, persons or entity making such determination
shall presume that Indemnitee is entitled to indemnification under this Agreement if Indemnitee has submitted a request for indemnification in accordance with Section 11(b) of this Agreement, and the Company shall have the burden of proof to
overcome that presumption in connection with the making by any person, persons or entity of any determination contrary to that presumption. Neither the failure of the Company (including by the Disinterested Directors or Independent Counsel) to have
made a determination prior to the commencement of any action pursuant to this Agreement that indemnification is proper in the circumstances because Indemnitee has met the applicable standard of conduct, nor an actual determination by the Company
(including by the Disinterested Directors or Independent Counsel) that Indemnitee has not met such applicable standard of conduct, shall be a defense to the action or create a presumption that Indemnitee has not met the applicable standard of
conduct. 
 (b) If the person, persons or entity empowered or selected under Section 12 of this Agreement to determine whether
Indemnitee is entitled to indemnification shall not have made a determination within thirty (30) days after receipt by the Company of the request therefor, the requisite determination of entitlement to indemnification shall, to the fullest
extent permitted by law, be deemed to have been made and Indemnitee shall be entitled to such indemnification, absent (i) a misstatement by Indemnitee of a material fact, or an omission of a material fact necessary to make Indemnitee’s
statement not materially misleading, in connection with the request for indemnification, or (ii) a final judicial determination that any or all such indemnification is expressly prohibited under applicable law; provided, however, that such 30-day period may be extended for a reasonable time, not to exceed an additional fifteen (15) days, if the person, persons or entity making the determination with respect to entitlement to indemnification in
good faith requires such additional time for the obtaining or evaluating of documentation and/or information relating thereto. 
 (c) The
termination of any Proceeding or of any claim, issue or matter therein, by judgment, order, settlement or conviction, or upon a plea of nolo contendere or its equivalent, shall not (except as otherwise expressly provided in this Agreement) of itself
adversely affect the right of Indemnitee to indemnification or create a presumption that Indemnitee did not act in good faith and in a manner which Indemnitee reasonably believed to be in or not opposed to the best interests of the Company or, with
respect to any criminal Proceeding, that Indemnitee had reasonable cause to believe that Indemnitee’s conduct was unlawful. 

  
 -10- 

 (d) For purposes of any determination of good faith, Indemnitee shall be deemed to have
acted in good faith if Indemnitee’s action is based on the records or books of account of the Enterprise, including financial statements, or on information supplied to Indemnitee by the directors, manager, or officers of the Enterprise in the
course of their duties, or on the advice of legal counsel for the Enterprise, its Board, any committee of the Board or any director, trustee, general partner, manager or managing member, or on information or records given or reports made to the
Enterprise, its Board, any committee of the Board or any director, trustee, general partner, manager or managing member, by an independent certified public accountant or by an appraiser or other expert selected by the Enterprise, its Board, any
committee of the Board or any director, trustee, general partner, manager or managing member. The provisions of this Section 13(d) shall not be deemed to be exclusive or to limit in any way the other circumstances in which Indemnitee may be
deemed or found to have met the applicable standard of conduct set forth in this Agreement. 
 (e) The knowledge and/or actions, or failure
to act, of any other director, officer, trustee, partner, manager, managing member, fiduciary, agent or employee of the Enterprise shall not be imputed to Indemnitee for purposes of determining the right to indemnification under this Agreement. 

14. REMEDIES OF INDEMNITEE. 

(a) In the event that (i) a determination is made pursuant to Section 12 of this Agreement that Indemnitee is not entitled to
indemnification under this Agreement, (ii) advancement of Expenses, to the fullest extent permitted by applicable law, is not timely made pursuant to Section 10 of this Agreement, (iii) no determination of entitlement to
indemnification shall have been made pursuant to Section 12(a) of this Agreement within thirty (30) days after receipt by the Company of the request for indemnification, (iv) payment of indemnification is not made pursuant to
Section 5, 6, 7 or the last sentence of Section 12(a) of this Agreement within ten (10) days after receipt by the Company of a written request therefor, (v) a contribution payment is not made in a timely manner pursuant to
Section 8 of this Agreement, (vi) payment of indemnification pursuant to Section 3 or 4 of this Agreement is not made within ten (10) days after a determination has been made that Indemnitee is entitled to indemnification, or
(vii) payment to Indemnitee pursuant to any hold harmless or exoneration rights under this Agreement or otherwise is not made in accordance with this Agreement, Indemnitee shall be entitled to an adjudication by the Delaware Court to such
indemnification, hold harmless, exoneration, contribution or advancement rights. Alternatively, Indemnitee, at Indemnitee’s option, may seek an award in arbitration to be conducted by a single arbitrator pursuant to the Commercial Arbitration
Rules of the American Arbitration Association. Except as set forth herein, the provisions of Delaware law (without regard to its conflict of laws rules) shall apply to any such arbitration. The Company shall not oppose Indemnitee’s right to
seek any such adjudication or award in arbitration. 
 (b) In the event that a determination shall have been made pursuant to
Section 12(a) of this Agreement that Indemnitee is not entitled to indemnification, any judicial proceeding or arbitration commenced pursuant to this Section 14 shall be conducted in all respects as a de novo trial, or arbitration, on the
merits and Indemnitee shall not be prejudiced by reason of that adverse determination. 

  
 -11- 

 (c) In any judicial proceeding or arbitration commenced pursuant to this Section 14,
Indemnitee shall be presumed to be entitled to be indemnified, held harmless, exonerated and to receive advancement of Expenses under this Agreement and the Company shall have the burden of proving Indemnitee is not entitled to be indemnified, held
harmless, exonerated and to receive advancement of Expenses, as the case may be, and the Company may not refer to or introduce into evidence any determination pursuant to Section 12(a) of this Agreement adverse to Indemnitee for any purpose. If
Indemnitee commences a judicial proceeding or arbitration pursuant to this Section 14, Indemnitee shall not be required to reimburse the Company for any advances pursuant to Section 10 until a final determination is made with respect to
Indemnitee’s entitlement to indemnification (as to which all rights of appeal have been exhausted or lapsed). 
 (d) If a determination
shall have been made pursuant to Section 12(a) of this Agreement that Indemnitee is entitled to indemnification, the Company shall be bound by such determination in any judicial proceeding or arbitration commenced pursuant to this
Section 14, absent (i) a misstatement by Indemnitee of a material fact, or an omission of a material fact necessary to make Indemnitee’s statement not materially misleading, in connection with the request for indemnification, or
(ii) a prohibition of such indemnification under applicable law. 
 (e) The Company shall be precluded from asserting in any judicial
proceeding or arbitration commenced pursuant to this Section 14 that the procedures and presumptions of this Agreement are not valid, binding and enforceable and shall stipulate in any such court or before any such arbitrator that the Company
is bound by all the provisions of this Agreement. 
 (f) The Company shall indemnify and hold harmless Indemnitee to the fullest extent
permitted by law against all Expenses and, if requested by Indemnitee, shall (within ten (10) days after the Company’s receipt of such written request) pay to Indemnitee, to the fullest extent permitted by applicable law, such Expenses
which are incurred by Indemnitee in connection with any judicial proceeding or arbitration brought by Indemnitee: (i) to enforce his rights under, or to recover damages for breach of, this Agreement or any other indemnification, hold harmless,
exoneration, advancement or contribution agreement or provision of the Charter, or the Bylaws now or hereafter in effect; or (ii) for recovery or advances under any insurance policy maintained by any person for the benefit of Indemnitee,
regardless of the outcome and whether Indemnitee ultimately is determined to be entitled to such indemnification, hold harmless or exoneration right, advancement, contribution or insurance recovery, as the case may be (unless such judicial
proceeding or arbitration was not brought by Indemnitee in good faith). 
 (g) Interest shall be paid by the Company to Indemnitee at the
legal rate under Delaware law for amounts which the Company indemnifies, holds harmless or exonerates, or advances, or is obliged to indemnify, hold harmless or exonerate or advance for the period commencing with the date on which Indemnitee
requests indemnification, to be held harmless, exonerated, contribution, reimbursement or advancement of any Expenses and ending with the date on which such payment is made to Indemnitee by the Company. 

  
 -12- 

 15. SECURITY. Notwithstanding anything herein to the contrary, except for
Section 27, to the extent requested by Indemnitee and approved by the Board, the Company may at any time and from time to time provide security to Indemnitee for the Company’s obligations hereunder through an irrevocable bank line of
credit, funded trust or other collateral. Any such security, once provided to Indemnitee, may not be revoked or released without the prior written consent of Indemnitee. 

16. NON-EXCLUSIVITY; SURVIVAL OF RIGHTS; INSURANCE; SUBROGATION. 

(a) The rights of Indemnitee as provided by this Agreement shall not be deemed exclusive of any other rights to which Indemnitee may at any
time be entitled under applicable law, the Charter, the Bylaws, any agreement, a vote of stockholders or a resolution of directors, or otherwise. No amendment, alteration or repeal of this Agreement or of any provision hereof shall limit or restrict
any right of Indemnitee under this Agreement in respect of any Proceeding (regardless of when such Proceeding is first threatened, commenced or completed) or claim, issue or matter therein arising out of, or related to, any action taken or omitted
by such Indemnitee in Indemnitee’s Corporate Status prior to such amendment, alteration or repeal. To the extent that a change in applicable law, whether by statute or judicial decision, permits greater indemnification, hold harmless or
exoneration rights or advancement of Expenses than would be afforded currently under the Charter, the Bylaws or this Agreement, it is the intent of the parties hereto that Indemnitee shall enjoy by this Agreement the greater benefits so afforded by
such change. No right or remedy herein conferred is intended to be exclusive of any other right or remedy, and every other right and remedy shall be cumulative and in addition to every other right and remedy given hereunder or now or hereafter
existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other right or remedy. 

(b) The Delaware General Corporation Law (the “DGCL”), the Charter and the Bylaws permit the Company to purchase and
maintain insurance or furnish similar protection or make other arrangements including, but not limited to, providing a trust fund, letter of credit, or surety bond (“Indemnification Arrangements”) on behalf of Indemnitee
against any liability asserted against Indemnitee or incurred by or on behalf of Indemnitee or in such capacity as a director, officer, employee or agent of the Company, or arising out of Indemnitee’s status as such, whether or not the Company
would have the power to indemnify Indemnitee against such liability under the provisions of this Agreement or under the DGCL, as it may then be in effect. The purchase, establishment, and maintenance of any such Indemnification Arrangement shall not
in any way limit or affect the rights and obligations of the Company or of Indemnitee under this Agreement except as expressly provided herein, and the execution and delivery of this Agreement by the Company and Indemnitee shall not in any way limit
or affect the rights and obligations of the Company or the other party or parties thereto under any such Indemnification Arrangement. 
 (c)
To the extent that the Company maintains an insurance policy or policies providing liability insurance for directors, officers, trustees, partners, managers, managing members, fiduciaries, employees, or agents of the Company or of any other
Enterprise which such person serves at the request of the Company, Indemnitee shall be covered by such policy or policies in accordance with its or their terms to the maximum extent of the coverage available for any such

  
 -13- 

 
director, officer, trustee, partner, managers, managing member, fiduciary, employee or agent under such policy or policies. If, at the time the Company receives notice from any source of a
Proceeding as to which Indemnitee is a party or a participant (as a witness, deponent or otherwise), the Company has director and officer liability insurance in effect, the Company shall give prompt notice of such Proceeding to the insurers in
accordance with the procedures set forth in the respective policies. The Company shall thereafter take all necessary or desirable action to cause such insurers to pay, on behalf of Indemnitee, all amounts payable as a result of such Proceeding in
accordance with the terms of such policies. 
 (d) In the event of any payment under this Agreement, the Company, to the fullest extent
permitted by law, shall be subrogated to the extent of such payment to all of the rights of recovery of Indemnitee, who shall execute all papers required and take all action necessary to secure such rights, including execution of such documents as
are necessary to enable the Company to bring suit to enforce such rights. 
 (e) The Company’s obligation to indemnify, hold harmless,
exonerate or advance Expenses hereunder to Indemnitee who is or was serving at the request of the Company as a director, officer, trustee, partner, manager, managing member, fiduciary, employee or agent of any other Enterprise shall be reduced by
any amount Indemnitee has actually received as indemnification, hold harmless or exoneration payments or advancement of expenses from such Enterprise. Notwithstanding any other provision of this Agreement to the contrary except for Section 27,
(i) Indemnitee shall have no obligation to reduce, offset, allocate, pursue or apportion any indemnification, hold harmless, exoneration, advancement, contribution or insurance coverage among multiple parties possessing such duties to
Indemnitee prior to the Company’s satisfaction and performance of all its obligations under this Agreement, and (ii) the Company shall perform fully its obligations under this Agreement without regard to whether Indemnitee holds, may
pursue or has pursued any indemnification, advancement, hold harmless, exoneration, contribution or insurance coverage rights against any person or entity other than the Company. 

(f) To the extent Indemnitee has rights to indemnification, advancement of expenses and/or insurance provided by MIT Sponsor or its affiliates
as applicable, (i) the Company shall be the indemnitor of first resort (i.e., that its obligations to Indemnitee are primary and any obligation of MIT Sponsor or its affiliates, as applicable, to advance expenses or to provide indemnification
for the same expenses or liabilities incurred by Indemnitee are secondary), (ii) the Company shall be required to advance the full amount of expenses incurred by Indemnitee and shall be liable for the full amount of all claims, liabilities,
damages, losses, costs and expenses (including amounts paid in satisfaction of judgments, in compromises and settlements, as fines and penalties and legal or other costs and reasonable expenses of investigating or defending against any claim or
alleged claim) to the extent legally permitted and as required by the terms of this Agreement, the Company’s organizational documents or other agreement, without regard to any rights Indemnitee may have against MIT Sponsor or its affiliates, as
applicable, and (iii) the Company irrevocably waives, relinquishes and releases MIT Sponsor and its affiliates, as applicable, from any and all claims against them for contribution, subrogation or any other recovery of any kind in respect
thereof. No advancement or payment by MIT Sponsor or its affiliates, as applicable, on behalf of Indemnitee with respect to any claim for which Indemnitee has sought indemnification from the Company shall affect the foregoing, and the Sponsor and
its affiliates, as applicable, shall have a right of contribution and be subrogated to the extent of such advancement or payment to all of the rights of recovery of Indemnitee against the Company.

 17. DURATION OF AGREEMENT. All agreements and obligations of the Company contained
herein shall continue during the period Indemnitee serves as a director or officer of the Company or as a director, officer, trustee, partner, manager, managing member, fiduciary, employee or agent of any other corporation, partnership, joint
venture, trust, employee benefit plan or other Enterprise which Indemnitee serves at the request of the Company and shall continue thereafter so long as Indemnitee shall be subject to any possible Proceeding (including any rights of appeal thereto
and any Proceeding commenced by Indemnitee pursuant to Section 14 of this Agreement) by reason of Indemnitee’s Corporate Status, whether or not Indemnitee is acting in any such capacity at the time any liability or expense is incurred for
which indemnification or advancement can be provided under this Agreement. 
 18. SEVERABILITY. If any provision or provisions of
this Agreement shall be held to be invalid, illegal or unenforceable for any reason whatsoever: (a) the validity, legality and enforceability of the remaining provisions of this Agreement (including, without limitation, each portion of any
Section, paragraph or sentence of this Agreement containing any such provision held to be invalid, illegal or unenforceable, that is not itself invalid, illegal or unenforceable) shall not in any way be affected or impaired thereby and shall remain
enforceable to the fullest extent permitted by law; (b) such provision or provisions shall be deemed reformed to the extent necessary to conform to applicable law and to give the maximum effect to the intent of the parties hereto; and
(c) to the fullest extent possible, the provisions of this Agreement (including, without limitation, each portion of any Section, paragraph or sentence of this Agreement containing any such provision held to be invalid, illegal or
unenforceable, that is not itself invalid, illegal or unenforceable) shall be construed so as to give effect to the intent manifested thereby. 

19. ENFORCEMENT AND BINDING EFFECT. 

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

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

  
 -15- 

 (d) The Company shall require and cause any successor (whether direct or indirect by
purchase, merger, consolidation or otherwise) to all, substantially all or a substantial part, of the business and/or assets of the Company, by written agreement in form and substance satisfactory to Indemnitee, expressly to assume and agree to
perform this Agreement in the same manner and to the same extent that the Company would be required to perform if no such succession had taken place. 

(e) The Company and Indemnitee agree herein that a monetary remedy for breach of this Agreement, at some later date, may be inadequate,
impracticable and difficult of proof, and further agree that such breach may cause Indemnitee irreparable harm. Accordingly, the parties hereto agree that Indemnitee may, to the fullest extent permitted by law, enforce this Agreement by seeking,
among other things, injunctive relief and/or specific performance hereof, without any necessity of showing actual damage or irreparable harm and that by seeking injunctive relief and/or specific performance, Indemnitee shall not be precluded from
seeking or obtaining any other relief to which Indemnitee may be entitled. The Company and Indemnitee further agree that Indemnitee shall, to the fullest extent permitted by law, be entitled to such specific performance and injunctive relief,
including temporary restraining orders, preliminary injunctions and permanent injunctions, without the necessity of posting bonds or other undertaking in connection therewith. The Company acknowledges that in the absence of a waiver, a bond or
undertaking may be required of Indemnitee by a court of competent jurisdiction. The Company hereby waives any such requirement of such a bond or undertaking to the fullest extent permitted by law. 

20. MODIFICATION AND WAIVER. No supplement, modification or amendment of this Agreement shall be binding unless executed in writing by
the Company and Indemnitee. No waiver of any of the provisions of this Agreement shall be deemed or shall constitute a waiver of any other provisions of this Agreement nor shall any waiver constitute a continuing waiver. 

21. NOTICES. All notices, requests, demands and other communications under this Agreement shall be in writing and shall be deemed to
have been duly given (i) if delivered by hand and receipted for by the party to whom said notice or other communication shall have been directed, or (ii) mailed by certified or registered mail with postage prepaid, on the third (3rd)
business day after the date on which it is so mailed:

Agreement, or such other address as Indemnitee shall provide in writing to the Company.

23. IDENTICAL COUNTERPARTS. This Agreement may be executed in one or more counterparts, each of which shall for all purposes be deemed

shall be asserted by or in the right of the Company against Indemnitee, Indemnitee’s spouse, heirs, executors or personal or legal representatives after the expiration of two years from the date of accrual of such cause of action, and any claim
or cause of action of the Company shall be extinguished and deemed released unless asserted by the timely filing of a legal action within such two-year period; provided, however, that if any shorter period of
limitations is otherwise applicable to any such cause of action such shorter period shall govern. 
 26. ADDITIONAL ACTS. If for the
validation of any of the provisions in this Agreement any act, resolution, approval or other procedure is required to the fullest extent permitted by law, the Company undertakes to cause such act, resolution, approval or other procedure to be
affected or adopted in a manner that will enable the Company to fulfill its obligations under this Agreement. 
 27. WAIVER OF CLAIMS TO
TRUST ACCOUNT. Indemnitee hereby agrees that it does not have any right, title, interest or claim of any kind (each, a “Claim”) in or to any monies in the trust account established in connection with the Company’s
initial public offering for the benefit of the Company and holders of shares issued in such offering, and hereby waives any Claim it may have in the future as a result of, or arising out of, any services provided to the Company and will not seek
recourse against such trust account for any reason whatsoever. 
 28. MAINTENANCE OF INSURANCE. The Company shall use commercially
reasonable efforts to obtain and maintain in effect during the entire period for which the Company is obligated to indemnify the Indemnitee under this Agreement, one or more policies of insurance with reputable insurance companies to provide the
officers/directors of the Company with coverage for losses from wrongful acts and omissions and to ensure the Company’s performance of its indemnification obligations under this Agreement. The Indemnitee shall be covered by such policy or
policies in accordance with its or their terms to the maximum extent of the coverage available for any such director or officer under such policy or policies. In all such insurance policies, the Indemnitee shall be named as an insured in such a
manner as to provide the Indemnitee with the same rights and benefits as are accorded to the most favorably insured of the Company’s directors and officers.
