 RE: Securities Subscription
Agreement 
 Ladies and Gentlemen: 
 This agreement
(this “Agreement”) is entered into on December 29, 2020 by and between DHC Sponsor, LLC, a Delaware limited liability company (the “Subscriber” or “you”), and DHC Acquisition Corp., a Cayman
Islands exempted company (the “Company”). Pursuant to the terms hereof, the Company hereby accepts the offer the Subscriber has made to purchase 7,187,500 Class B ordinary shares, $0.0001 par value per share (the
“Shares”), up to 937,500 of which are subject to surrender and cancellation by you if the underwriters of the initial public offering (“IPO”) of units (“Units”) of the Company do not fully exercise
their over-allotment option (the “Over-allotment Option”). The Company’s and the Subscriber’s agreements regarding such Shares are as follows: 
  

	1.	 Purchase of Securities. 

 

	 	1.1.	 Subscription and Purchase of Shares. For the sum of $25,000 (the “Purchase Price”),
which the Company acknowledges receiving in the form of payment of its $25,000 invoice to Maples and Calder, dated as of December 22, 2020 and attached hereto as Exhibit A, the Company hereby issues the Shares to the Subscriber, and the
Subscriber hereby subscribes for and purchases the Shares from the Company, 937,500 of which are subject to surrender and cancellation, on the terms and subject to the conditions set forth in this Agreement. All references in this Agreement to
shares of the Company being surrendered and canceled shall take effect as surrenders and cancellations for no consideration of such shares as a matter of Cayman Islands law. The Subscriber hereby surrenders for no consideration the one Class B
ordinary share transferred to it at the time of the incorporation of the Company. 

  

	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 or (iii) any law, statute, rule or regulation to which the Subscriber is subject, or any agreement, order, judgment or decree to which the Subscriber is subject. 

	 	2.1.3.	 Registration and Authority. The Subscriber is a Cayman Islands exempted limited partnership, validly
existing and possessing 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 sold 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: (i) an effective registration statement under the Securities Act or
(ii) 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 and/or its prospects.

  

	 	2.1.6.	 Regulation D Offering. 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 to
“accredited investors” within the meaning of Section 501(a) of Regulation D under the Securities Act or similar exemptions under federal and state law. 

 

	 	2.1.7.	 Investment Purposes. The Subscriber is subscribing for and 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. The Subscriber did not decide to 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. 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” within the meaning of Rule 144(a)(3) under the Securities Act, and Subscriber
understands that the certificates 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 pursuant to: (i) registration under the Securities Act, or (ii) an available exemption from registration. 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 resell 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 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 or necessary 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 subscribe for and
purchase the Shares, the Company hereby represents and warrants to the Subscriber and agrees with the Subscriber as follows: 

  

	 	2.2.1.	 Incorporation and Corporate Power. The Company is a Cayman Islands exempted company 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. Upon execution and delivery by the Company, this Agreement will be a legal, valid and binding agreement of the Company, enforceable against the Company 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). 

  

	 	2.2.2.	 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 memorandum and articles of association of the Company, (ii) any agreement, indenture or instrument to which the Company is
a party or (iii) any law, statute, rule or regulation to which the Company is subject, or any agreement, order, judgment or decree to which the Company is subject. 

 

	 	2.2.3.	 Title to Securities. Upon issuance in accordance with, and payment pursuant to, the terms hereof, and
registration in the Company’s register of members, the Shares will be duly and validly issued, fully paid and nonassessable. Upon issuance in accordance with, and payment pursuant to, the terms hereof, and registration in the Company’s
register of members, 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, (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 General Solicitation. Neither the Company, nor any of its officers, directors, employees, agents or
stockholders has either directly or indirectly, including, through a broker or finder (i) engaged in any general solicitation, or (ii) published any general advertisement in connection with the offer and sale of the Shares

	 	2.2.5.	 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 seeks to
recover damages or to obtain other relief in connection with any transactions. 

  

	3.	 Surrender and Cancellation of Shares. 

 

	 	3.1.	 Partial or No Exercise of the Over-allotment Option. In the event the Over-allotment Option granted to
the representative(s) of the underwriters of the Company’s IPO is not exercised in full, the Subscriber acknowledges and agrees that it shall surrender for cancellation any and all rights to such number of Shares (up to an aggregate of 937,500
Shares and pro rata based upon the percentage of the Over-allotment Option exercised) such that immediately following such 

surrender, the Subscriber (and all other initial shareholders prior to the IPO, if any) will own an aggregate number of Shares (not including
ordinary shares issuable upon exercise of any warrants or any ordinary shares purchased by Subscriber in the Company’s IPO or in the aftermarket) equal to 20% of the issued and outstanding ordinary shares of the Company immediately following
the IPO. 
  

	 	3.2.	 Termination of Rights as Shareholder. If any of the Shares are surrendered and cancelled 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.

  

	4.	 Waiver of Liquidation Distributions; Redemption Rights. In connection with the Shares subscribed for and
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 shareholders 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 subscribes for and purchases ordinary shares in the IPO or in the aftermarket, any additional Shares so subscribed for and 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 ordinary shares into funds held in the Trust Account upon the successful completion of an initial business combination.

  

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

 “THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE UNITED STATES 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.” 
 “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.” 

	 	5.3.	 Additional Shares or Substituted Securities. In the event of the declaration of a share capitalization,
the declaration of an extraordinary dividend payable in a form other than Shares, a spin-off, a share sub-division, an adjustment in conversion ratio, a recapitalization
or a similar transaction affecting the Company’s outstanding Shares 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 and/or class of Shares subject to this Section 5 and Section 3. 

  

	 	5.4.	 Registration Rights. 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 and Shareholder Rights Agreement to be entered into with the
Company prior to the closing of the IPO. 

  

	6.	 Other Agreements. 

 

	 	6.1.	 Further Assurances. 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: (i) in writing and delivered personally or sent by first class registered or certified mail, overnight courier service or facsimile or electronic transmission to the address designated in writing, (ii) by facsimile to the number
most recently provided to such party or such other address or fax number as may be designated in writing by such party and (iii) by electronic mail, to the electronic mail address most recently provided to such party or such other electronic
mail address as may be designated in writing by such party. Any notice or other communication so transmitted shall be deemed to have been given on the day of delivery, if delivered personally, on the business day following receipt of written
confirmation, if sent by facsimile or electronic transmission, one (1) business day after delivery to an overnight courier service or five (5) days after mailing if sent by mail. 

 

	 	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 on Form S-1 associated with the Company’s IPO, 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. 

 

	 	6.4.	 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 a 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. Except with respect to transfers of the Shares to a controlled affiliate of the Subscriber,
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 the state of New York applicable to contracts wholly performed within the borders of such state, without giving effect to the conflict of law principles thereof. 

 

	 	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. 

 

	 	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 save 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 subdivisions 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 parties hereto have participated jointly in the negotiation and drafting of this
Agreement. If an ambiguity or question of intent or interpretation arises, this Agreement will be construed as if drafted jointly by the parties hereto and no presumption or burden of proof will arise favoring or disfavoring any party hereto because
of the authorship of any provision of this Agreement. 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 subdivision 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. 

  

	 	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. 

 

	7.	 Voting and Redemption of Shares. 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 shareholders and shall not seek redemption or repurchase with respect to such Shares. Additionally, the Subscriber agrees not to tender any Shares in connection
with a tender offer presented to the Company’s shareholders in connection with an initial business combination negotiated by the Company.

Permitted Transferee (or a change of control of such Lock-Up Party or Permitted Transferee) after the Transfer with the result and effect that the Lock-Up Party has
indirectly made a Transfer of Lock-Up Securities by using a Permitted Transferee, which Transfer would not have been directly permitted under this Article II had such change in such relationship occurred prior
to such Transfer), or (ii) enter into a written plan meeting the requirements of Rule 10b5-1 under the Exchange Act after the date of this Agreement relating to the sale of the undersigned’s Lock-Up Securities, provided that (A) the securities subject to such plan may not be sold until after the expiration of the Lock-Up Period and (B) the Company
shall not be required to effect, and the undersigned shall not effect or cause to be effected, any public filing, report or other public announcement regarding the establishment of the trading plan.

 “THE SECURITIES

EXCEPT IN ACCORDANCE WITH THE TERMS OF THE LOCK-UP AGREEMENT BETWEEN THE COMPANY AND SECURITYHOLDER.” 
 3.
Additional Agreements. 
 3.1 Confidentiality. Until the Expiration Time, each Lock-Up
Party will and will direct their Affiliates to keep confidential and not disclose any non-public information relating to DCRB or the Company and their respective subsidiaries, including the existence or terms
of, or transactions contemplated by, this Agreement, the Business Combination Agreement or the other Transaction Documents, except to the extent that such information (i) was, is or becomes generally available to the public after the date
hereof other than as a result of a disclosure by such Lock-Up Party in breach of this Section 3.1, (ii) is, was or becomes available to such
Lock-Up Party on a non-confidential basis from a source other than DCRB or the Company, or (iii) is or was independently developed by such Lock-Up Party after the date hereof. Notwithstanding the foregoing, such information may be disclosed to the extent required to be disclosed in a judicial or administrative proceeding, or otherwise required to be
disclosed by applicable Law (including complying with any oral or written questions, interrogatories, requests for information or documents, subpoena, civil investigative demand or similar process to which such disclosing party is subject),
provided that such Lock-Up Party gives DCRB or the Company, as applicable, prompt notice of such request(s) or requirement(s), to the extent practicable (and not prohibited by Law), so that DCRB or the
Company may seek, at its expense, an appropriate protective order or similar relief (and such Lock-Up Party shall reasonably cooperate with such efforts it being understood that such obligation to reasonably
cooperate does not require a Lock-Up Party to itself commence litigation regarding such protective order or similar relief). 

3.2 DCRB Board Release. Notwithstanding anything in this Agreement to the contrary, it is understood and agreed that, from and after the
Closing Date, the Board of Directors of DCRB shall be entitled to release any Lock-Up Party from any or all of its obligations hereunder, in each case on behalf of DCRB and the Company, provided,
however, that if one Lock-Up Party is released, the other Lock-Up Parties shall also be similarly released to the same relative extent as the released Lock-Up Party. 
 4. Representations and Warranties of the Lock-Up Parties.
Each Lock-Up Party hereby represents and warrants, severally and not jointly, to the Company and DCRB as follows: 

4.1 Due Authority. Such Lock-Up Party has the full power and authority to execute and deliver
this Agreement and perform its obligations hereunder. If such Lock-Up Party is an individual, the signature to this agreement is genuine and such Lock-Up Party has legal
competence and capacity to execute the same. This Agreement has been duly and validly executed and delivered by such Lock-Up Party and, assuming due execution and delivery by the other parties hereto,
constitutes a legal, valid and binding obligation of such Lock-Up Party, enforceable against such Lock-Up Party in accordance with its terms, except as limited by
applicable bankruptcy, insolvency, reorganization, moratorium and other laws of general application affecting enforcement of creditors’ rights generally, by general equitable principles. 

  
 4 

 4.2 No Conflict; Consents. 

(a) The execution and delivery of this Agreement by such Lock-Up Party does not, and
the performance by such Lock-Up Party of the obligations under this Agreement and the compliance by such Lock-Up Party with any provisions hereof do not and will not:
(i) conflict with or violate any Law applicable to such Lock-Up Party, (ii) if such Lock-Up Party is an entity, conflict with or violate the certificate of
incorporation or bylaws or any equivalent organizational documents of such Lock-Up Party, or (iii) result in any breach of, or constitute a default (or an event, which with notice or lapse of time or
both, would become a material default) under, or give to others any rights of termination, amendment, acceleration or cancellation of, or result in the creation of a lien on any of the securities of the Company owned by such Lock-Up Party pursuant to any note, bond, mortgage, indenture, contract, agreement, lease, license, permit, franchise or other instrument or obligation to which such Lock-Up
Party is a party or by which such Lock-Up Party is bound, except, in the case of clauses (i) and (iii), as would not reasonably be expected, individually or in the aggregate, to materially
impair the ability of such Lock-Up Party to perform its obligations hereunder or to consummate the transactions contemplated hereby. 

(b) The execution and delivery of this Agreement by such Lock-Up Party does not, and
the performance of this Agreement by such Lock-Up Party will not, require any consent, approval, authorization or permit of, or filing or notification to, or expiration of any waiting period by any
Governmental Authority or any other Person with respect to such Lock-Up Party, other than those set forth as conditions to closing in the Business Combination Agreement. 

4.3 Absence of Litigation. As of the date hereof, there is no litigation, suit, claim, charge, grievance, action, proceeding, audit or
investigation by or before any Governmental Authority (an “Action”) pending against, or, to the knowledge of such Lock-Up Party after reasonable inquiry, threatened against such Lock-Up Party that would reasonably be expected to materially impair the ability of such Lock-Up Party to perform its obligations hereunder or to consummate the transactions
contemplated hereby. 
 4.4 Absence of Conflicting Agreements. Such Lock-Up Party has
not entered into any agreement, arrangement or understanding that is otherwise materially inconsistent with, or would materially interfere with, or prohibit or prevent it from satisfying, its obligations pursuant to this Agreement. 

5. Fiduciary Duties. The covenants and agreements set forth herein shall not prevent any designee of any Lock-Up
Party from serving on the Board of Directors of the Company or from taking any action, subject to the provisions of the Business Combination Agreement, while acting in such designee’s capacity as a director of the Company. Each Lock-Up Party is entering into this Agreement solely in its capacity as the anticipated owner of DCRB Securities following the consummation of the Merger. 

  
 5 

 6. Termination. Upon termination of this Agreement, none of the parties hereto shall have any further
obligations or liabilities under this Agreement; provided, that nothing in this Section 6 shall relieve any party hereto of liability for any willful material breach of this Agreement prior to its termination. 

7. Miscellaneous. 
 7.1
Severability. In the event that any term, provision, covenant or restriction of this Agreement, or the application thereof, is held to be illegal, invalid or unenforceable under any present or future Law: (a) such provision will be fully
severable; (b) this Agreement will be construed and enforced as if such illegal, invalid or unenforceable provision had never comprised a part hereof; and (c) all other provisions of this Agreement shall nevertheless remain in full force
and effect so long as the economic or legal substance is not affected in any manner materially adverse to any party. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties hereto
shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in a mutually acceptable manner in order than the transactions contemplated hereby be consummated as originally
contemplated to the fullest extent possible. 
 7.2 Non-survival of Representations and
Warranties. None of the representations, warranties, covenants, obligations or other agreements in this Agreement or in any schedule, statement, instrument or other document delivered pursuant to this Agreement shall survive the Expiration Time.

 7.3 Assignment. No party hereto may assign, directly or indirectly, including by operation of Law, either this Agreement or any of
its rights, interests or obligations hereunder without the prior written approval of the other parties hereto, except with respect to a Transfer completed in accordance with Section 2.2. Subject to the first sentence of
this Section 7.3, this Agreement shall be binding upon and shall inure to the benefit of the parties hereto and their respective successors and permitted assigns. Any assignment in violation of this
Section 7.3 shall be void ab initio. 
 7.4 Amendments and Modifications. This Agreement may be
amended by the parties hereto at any time by execution of an instrument in writing signed by (1) DCRB, (2) the Company and (3), if prior to the Closing Date, by Lock-Up Parties holding 75% of the
shares of the Company (measured by shares of the Company’s common stock, par value $0.001 per share (the “Company Common Stock”), and assuming the exercise and conversion of all then-outstanding Company securities into
shares of the Company Common Stock) then held by Lock-Up Parties, and, if after the Closing Date, by Lock-Up Parties holding 75% of the
Lock-Up Securities (assuming the exercise of all then-outstanding warrants and options that are Lock-Up Securities) that are then subject to this Agreement. Any such
amendment shall be binding on all the Lock-Up Parties, provided that no amendment shall be binding upon any Lock-Up Parties to the extent that it materially increases
any obligation upon or otherwise materially adversely change the rights of, any Lock-Up Party, except upon the written consent of such Lock-Up Parties.

 7.5 Specific Performance. The parties hereto agree that irreparable damage would
occur if any provision of this Agreement were not performed in accordance with the terms hereof, and, accordingly, that the parties shall be entitled to an injunction or injunctions to prevent breaches of this Agreement or to enforce specifically
the performance of the terms and provisions hereof in any Delaware Chancery Court, or, if that court does not have jurisdiction, in any federal court located in the State of Delaware or any other Delaware state court without proof of actual damages
or otherwise, in addition to any other remedy to which they are entitled at Law or in equity as expressly permitted in this Agreement. Each of the parties hereby further waives (i) any defense in any action for specific performance that a
remedy at Law would be adequate and(ii) any requirement under any Law to post security or a bond as a prerequisite to obtaining equitable relief. 

7.6 Notices. All notices, consents and other communications hereunder shall be in writing and shall be given (and shall be deemed to
have been duly given upon receipt) by delivery in person, by email (provided no “bounceback” or notice of non-delivery is received) or by registered or certified mail (postage prepaid, return

EXTENT PERMITTED BY APPLICABLE LAW ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY WITH RESPECT TO ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY. EACH OF THE PARTIES
HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THAT FOREGOING WAIVER AND
(B) ACKNOWLEDGES THAT IT AND THE OTHER HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT AND THE TRANSACTIONS CONTEMPLATED HEREBY, AS APPLICABLE, BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS
SECTION 7.8. 
 7.9 Entire Agreement; Third-Party Beneficiaries. This Agreement constitutes the entire
agreement among the parties hereto with respect to the subject matter hereof and supersedes all prior agreements and understandings, both written and oral, among the parties hereto with respect to the subject matter hereof, and is not intended to

 7.10 Counterparts. This Agreement may be

right, privilege or remedy under this Agreement shall operate as a waiver of such power, right, privilege or remedy; and no single or partial exercise of any such power, right, privilege or remedy shall preclude any other or further exercise thereof
or of any other power, right, privilege or remedy. Neither party shall be deemed to have waived any claim available to such party arising out of this Agreement, or any power, right, privilege or remedy under this Agreement, unless the waiver of such
claim, power, right, privilege or remedy is expressly set forth in a written instrument duly executed and delivered on behalf of such waiving party; and any such waiver shall not be applicable or have any effect except in the specific instance in
which it is given. 
 7.16 Several Liability. The liability of any Lock-Up Party hereunder is
several (and not joint). Notwithstanding any other provision of this Agreement, in no event will any Lock-Up Party be liable for any other Lock-Up Party’s breach of

claim (whether in tort, contract or otherwise, or granted by statute or otherwise, whether by or through attempted piercing of the corporate, limited partnership or limited liability company veil or any other theory or doctrine, including alter ego
or otherwise) for any obligations or liabilities based upon, arising under, out of, in connection with, or related in any manner to this Agreement. Without limiting the rights of any party against the other parties hereto, in no event shall any
party or any of its affiliates seek to enforce this Agreement against, make any claims for breach of this Agreement against, or seek to recover monetary damages from, any Non-Recourse Party.
