 Re: Initial Public Offering

 Ladies and Gentlemen: 
 This letter (this
“Letter Agreement”) is being delivered to you in accordance with the Underwriting Agreement (the “Underwriting Agreement”) entered into or proposed to be entered into by and among Lamar Partnering
Corporation, a Cayman Islands exempted company (the “Company”), and Morgan Stanley & Co. LLC and Citigroup Global Markets, Inc., as the representatives (the “Representatives”) of the several
underwriters (the “Underwriters”) named therein, relating to an underwritten initial public offering (the “Public Offering”) of 34,500,000 of the Company’s units (including
4,500,000 units that may be purchased pursuant to the Underwriters’ option to purchase additional units, the “Units”), each comprising of one of the Company’s Class A ordinary shares, par value
$0.0001 per share (the “Ordinary Shares”), and one-fourth of one redeemable warrant (each whole warrant, a “Warrant”). Each Warrant entitles the holder thereof
to purchase one Ordinary Share at a price of $11.50 per share, subject to adjustment. The Units will be sold in the Public Offering pursuant to a registration statement on Form S-1 and a prospectus (the
“Prospectus”) filed by the Company with the U.S. Securities and Exchange Commission (the “Commission”). Certain capitalized terms used herein are defined in paragraph 1 hereof. 

In order to induce the Company and the Underwriters to enter into the Underwriting Agreement and to proceed with the Public Offering and for
other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Lamar Partnering Sponsor LLC (the “Sponsor”) and each of the undersigned (each, an “Insider” and,
collectively, the “Insiders”) hereby agree with the Company as follows: 
 1. Definitions. As used herein,
(i) “Business Combination” shall mean a merger, share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses or entities; (ii) “Founder
Shares” shall mean the 8,625,000 Class F ordinary shares of the Company, par value $0.0001 per share, outstanding prior to the consummation of the Public Offering; (iii) “Private Placement Units” shall
mean the Units of the Company that will be acquired by the Sponsor for an aggregate purchase price of $10,000,000, or $10.00 per Unit, in a private placement that shall close simultaneously with the consummation of the Public Offering;
(iv) “Public Shareholders” shall mean the holders of Ordinary Shares included in the Units issued in the Public Offering; (v) “Public Shares” shall mean the Ordinary Shares included in the
Units issued in the Public Offering; (vi) “Trust Account” shall mean the trust account into which a portion of the net proceeds of the Public Offering and the sale of the Private Placement Units shall be deposited;
(vii) “Transfer” shall mean the (a) sale of, offer to sell, contract or agreement to sell, hypothecate, pledge, grant of any option to purchase or otherwise dispose of or agreement to dispose of, directly or
indirectly, or establishment or increase of a put equivalent position or liquidation with respect to or decrease of a call equivalent position within the meaning of Section 16 of the Securities Exchange Act of 1934, as amended, and the rules
and regulations of the Commission promulgated thereunder with respect to, any security, (b) entry into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of any security,
whether any such transaction is to be settled by delivery of such securities, in cash or otherwise, or (c) public announcement of any intention to effect any transaction specified in clause (a) or (b); and
(viii) “Articles” shall mean the Company’s Amended and Restated Memorandum and Articles of Association, as the same may be amended from time to time. 

2. Representations and Warranties. 

(a) The Sponsor and each Insider, with respect to itself, herself or himself, represent and warrant to the Company that it, she or he has the
full right and power, without violating any agreement to which it, she or he is bound (including, without limitation, any non-competition or non-solicitation agreement
with any employer or former employer), to enter into this Letter Agreement, as applicable, and to serve as an officer of the Company and/or a director on the Company’s Board of Director (the “Board”), as applicable, and
each Insider hereby consents to being named in the Prospectus, road show and any other materials as an officer and/or director of the Company, as applicable. 

 (b) Each Insider represents and warrants, with respect to herself or himself, that such
Insider’s biographical information furnished to the Company (including any such information included in the Prospectus) is true and accurate in all material respects and does not omit any material information with respect to such Insider’s
background. The Insider’s questionnaire furnished to the Company is true and accurate in all material respects. Each Insider represents and warrants that such Insider is not subject to or a respondent in any legal action for, any injunction, cease-and-desist order or order or stipulation to desist or refrain from any act or practice relating to the offering of securities in any jurisdiction; such Insider has never
been convicted of, or pleaded guilty to, any crime (i) involving fraud, (ii) relating to any financial transaction or handling of funds of another person, or (iii) pertaining to any dealings in any securities and such Insider is not
currently a defendant in any such criminal proceeding; and such Insider has never been suspended or expelled from membership in any securities or commodities exchange or association or had a securities or commodities license or registration denied,
suspended or revoked. 
 3. Business Combination Vote. It is acknowledged and agreed that the Company shall not enter into a
definitive agreement regarding a proposed Business Combination without the prior consent of the Sponsor. The Sponsor and each Insider, with respect to itself or herself or himself, agrees that if the Company seeks shareholder approval of a proposed
initial Business Combination, then in connection with such proposed initial Business Combination, it, she or he, as applicable, shall vote all Founder Shares and any Public Shares held by it, her or him, as applicable, in favor of such proposed
initial Business Combination (including any proposals recommended by the Board in connection with such Business Combination) and not redeem any Public Shares held by it, her or him, as applicable, in connection with such shareholder approval. 

4. Failure to Consummate a Business Combination; Trust Account Waiver. 

(a) The Sponsor and each Insider hereby agree, with respect to itself, herself or himself, that in the event that the Company fails to
consummate its initial Business Combination within the time period set forth in the Articles, the Sponsor and each Insider shall take all reasonable steps to cause the Company to (i) cease all operations except for the purpose of winding up;
(ii) as promptly as reasonably possible but not more than 10 business days thereafter, redeem 100% of the Public Shares, at a per-share price, payable in cash, equal to the aggregate amount then on
deposit in the Trust Account, including interest earned on the funds held in the Trust Account and not previously released to the Company to pay taxes (less up to $100,000 of interest to pay dissolution expenses), divided by the number of then
outstanding Public Shares, which redemption will completely extinguish Public Shareholders’ rights as shareholders (including the right to receive further liquidation distributions, if any); and (iii) as promptly as reasonably possible
following such redemption, subject to the approval of the Company’s remaining shareholders and the Board, liquidate and dissolve, subject in the case of clauses (ii) and (iii) to the Company’s obligations under Cayman Islands law
to provide for claims of creditors and in all cases subject to the other requirements of applicable law. The Sponsor and each Insider agree not to propose any amendment to the Articles (i) that would modify the substance or timing of the
Company’s obligation to provide holders of the Public Shares the right to have their shares redeemed in connection with an initial Business Combination or to redeem 100% of the Public Shares if the Company does not complete an initial Business
Combination within the required time period set forth in the Articles or (ii) with respect to any provision relating to the rights of holders of Public Shares unless the Company provides its Public Shareholders with the opportunity to redeem
their Public Shares upon approval of any such amendment at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest earned on the funds held in
the Trust Account and not previously released to the Company to pay taxes, if any, divided by the number of then-outstanding Public Shares. 

(b) The Sponsor and each Insider, with respect to itself, herself or himself, acknowledges that it, she or he has no right, title, interest or
claim of any kind in or to any monies held in the Trust Account or any other asset of the Company as a result of any liquidation of the Company with respect to the Founder Shares held by it, her or him, if any. The Sponsor and each of the Insiders
hereby further waive, with respect to any Founder Shares and Public Shares held by it, her or him, as applicable, any redemption rights it, she or he may have in connection with the consummation of a Business Combination, including, without
limitation, any such rights available in the context of a shareholder vote to approve such Business Combination or a shareholder vote to approve an amendment to the Articles (i) that would modify the substance or timing of the Company’s
obligation to provide holders of the Public Shares the right to have their shares redeemed in connection with an initial Business Combination or to redeem 100% of the Public Shares if the Company has not consummated an initial Business Combination
within the time period set forth in the Articles or (ii) with respect to any provision relating to the rights of holders of Public Shares (although the Sponsor and the Insiders shall be entitled to liquidation rights with respect to any Public
Shares they hold if the Company fails to consummate a Business Combination within the required time period set forth in the Articles). 

 5. Lock-up; Transfer Restrictions. 

(a) The Sponsor and the Insiders agree that they shall not Transfer any Founder Shares (the “Founder Shares Lock-up”) until the earliest of (A) one year after the completion of an initial Business Combination and (B) the date following the completion of an initial Business Combination on which the
Company completes a liquidation, merger, share exchange or other similar transaction that results in all of the Company’s shareholders having the right to exchange their Ordinary Shares for cash, securities or other property (the
“Founder Shares Lock-up Period”). Notwithstanding the foregoing, if, subsequent to a Business Combination, the closing price of the Ordinary Shares equals or exceeds $12.00 per share
(as adjusted for share sub-divisions, share capitalizations, share consolidations, reorganizations, recapitalizations and the like) for any 20 trading days within a
30-trading day period commencing at least 150 days after the Company’s initial Business Combination, the Founder Shares shall be released from the Founder Shares
Lock-up. 
 (b) The Sponsor and Insiders agree that they shall not effectuate any Transfer of
Private Placement Units or Ordinary Shares underlying such warrants until 30 days after the completion of an initial Business Combination. 

(c) Notwithstanding the provisions set forth in paragraphs 5(a) and (b), Transfers of the Founder Shares, Private Placement
Units and Ordinary Shares and Warrants underlying the Private Placement Units are permitted (a) to the Company’s officers or directors, any affiliate or family member of any of the Company’s officers or directors, any members or
partners of the Sponsor or their affiliates, any affiliates of the Sponsor, or any employees of such affiliates; (b) in the case of an individual, by gift to a member of one of the individual’s immediate family or to a trust, the
beneficiary of which is a member of the individual’s immediate family, an affiliate of such person or to a charitable organization; (c) in the case of an individual, by virtue of laws of descent and distribution upon death of the
individual; (d) in the case of an individual, pursuant to a qualified domestic relations order; (e) by private sales or transfers made in connection with any forward purchase agreement or similar arrangement or in connection with the
consummation of a Business Combination at prices no greater than the price at which the Founder Shares, Private Placement Units or Ordinary Shares, as applicable, were originally purchased; (f) by virtue of the Sponsor’s organizational
documents upon liquidation or dissolution of the Sponsor; (g) to the Company for no value for cancellation in connection with the consummation of an initial Business Combination; (h) in the event of the Company’s liquidation prior to
the completion of a Business Combination; or (i) in the event of completion of a liquidation, merger, share exchange or other similar transaction which results in all of the Company’s Public Shareholders having the right to exchange their
Ordinary Shares for cash, securities or other property subsequent to the completion of an initial Business Combination; provided, however, that in the case of clauses (a) through (f), these permitted transferees must enter into a
written agreement agreeing to be bound by these transfer restrictions. 
 (d) (d) During the period commencing on the effective date of the
Underwriting Agreement and ending 180 days after such date, the Sponsor and each Insider shall not, without the prior written consent of Morgan Stanley & Co. LLC and Citigroup Global Markets, Inc. Transfer any Units, Ordinary Shares,
Warrants or any other securities convertible into, or exercisable or exchangeable for, Ordinary Shares held by it, her or him, as applicable, subject to certain exceptions enumerated in Section [    ] of the Underwriting
Agreement. 
 6. Remedies. The Sponsor and each of the Insiders hereby agree and acknowledge that (i) each of the Underwriters
and the Company would be irreparably injured in the event of a breach by the Sponsor or such Insider of its, her or his obligations, as applicable under paragraphs 3, 4, 5, 7, 10 and 11,
(ii) monetary damages may not be an adequate remedy for such breach and (iii) the non-breaching party shall be entitled to injunctive relief, in addition to any other remedy that such party may have
in law or in equity, in the event of such breach. 
 7. Payments by the Company. Except as disclosed in the Prospectus, neither the
Sponsor nor any affiliate of the Sponsor nor any director or officer of the Company nor any affiliate of the officers shall receive from the Company any finder’s fee, reimbursement, consulting fee, monies in respect of any payment of a loan or
other compensation prior to, or in connection with any services rendered in order to effectuate the consummation of the Company’s initial Business Combination (regardless of the type of transaction that it is). 

8. Director and Officer Liability Insurance. The Company will maintain an insurance policy or policies providing directors’ and
officers’ liability insurance, and the Insiders 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 of the Company’s directors or officers. 

 9. Termination. This Letter Agreement shall terminate on the earlier of (i) the
expiration of the Founder Shares Lock-up Period and (ii) the liquidation of the Company. 
 10.
Indemnification. In the event of the liquidation of the Trust Account upon the failure of the Company to consummate its initial Business Combination within the time period set forth in the Articles, the Sponsor (the
“Indemnitor”) agrees to indemnify and hold harmless the Company against any and all loss, liability, claim, damage and expense whatsoever (including, but not limited to, any and all legal or other expenses reasonably incurred
in investigating, preparing or defending against any litigation, whether pending or threatened) to which the Company may become subject as a result of any claim by (i) any third party for services rendered or products sold to the Company
(except for the Company’s independent auditors) or (ii) any prospective target business with which the Company has discussed entering into a transaction agreement (a “Target”); provided, however, that
such indemnification of the Company by the Indemnitor (x) shall apply only to the extent necessary to ensure that such claims by a third party for services rendered or products sold to the Company or a Target do not reduce the amount of funds
in the Trust Account to below the lesser of (i) $10.00 per Public Share and (ii) the actual amount per Public Share held in the Trust Account as of the date of the liquidation of the Trust Account if less than $10.00 per Public Share due
to reductions in the value of the trust assets, in each case net of interest that may be withdrawn to pay the Company’s tax obligations, (y) shall not apply to any claims by a third party or Target who executed a waiver of any and all
rights to the monies held in the Trust Account (whether or not such waiver is enforceable) and (z) shall not apply to any claims under the Company’s indemnity of the Underwriters against certain liabilities, including liabilities under the
Securities Act of 1933, as amended. The Indemnitor shall have the right to defend against any such claim with counsel of its choice reasonably satisfactory to the Company if, within 15 days following written receipt of notice of the claim to
the Indemnitor, the Indemnitor notifies the Company in writing that it shall undertake such defense. 
 11. Forfeiture of Founder
Shares. To the extent that the Underwriters do not exercise their option to purchase additional Units within 45 days from the date of the Prospectus in full (as further described in the Prospectus), the Sponsor agrees to automatically
surrender to the Company for no consideration, for cancellation at no cost, an aggregate number of Founder Shares so that the number of Founder Shares will equal of 20% of the sum of the total number of Ordinary Shares and Founder Shares outstanding
at such time. The Sponsor and Insiders further agree that to the extent that the size of the Public Offering is increased or decreased, the Company will effect a share capitalization or a share repurchase, as applicable, with respect to the Founder
Shares immediately prior to the consummation of the Public Offering in such amount as to maintain the number of Founder Shares at 20% of the sum of the total number of Ordinary Shares and Founder Shares outstanding at such time. 

12. Entire Agreement. This Letter Agreement constitutes the entire agreement and understanding of the parties hereto in respect of the
subject matter hereof and supersedes all prior understandings, agreements, or representations by or among the parties hereto, written or oral, to the extent they relate in any way to the subject matter hereof or the transactions contemplated hereby.
This Letter Agreement may not be changed, amended, modified or waived (other than to correct a typographical error) as to any particular provision, except by a written instrument executed by all parties hereto. 

13. Assignment. No party hereto may assign either this Letter Agreement or any of its rights, interests, or obligations hereunder
without the prior written consent of the other parties. Any purported assignment in violation of this paragraph shall be void and ineffectual and shall not operate to transfer or assign any interest or title to the purported assignee. This Letter
Agreement shall be binding on the Sponsor, each of the Insiders and each of their respective successors, heirs, personal representatives and assigns and permitted transferees. 

14. Counterparts. This Letter Agreement may be executed in any number of original or electronic counterparts, and each of such
counterparts shall for all purposes be deemed to be an original, and all such counterparts shall together constitute but one and the same instrument. 

15. Effect of Headings. The paragraph headings herein are for convenience only and are not part of this Letter Agreement and shall not
affect the interpretation thereof. 
 16. Severability. This Letter Agreement shall be deemed severable, and the invalidity or
unenforceability of any term or provision hereof shall not affect the validity or enforceability of this Letter Agreement or of any other term or provision hereof. Furthermore, in lieu of any such invalid or unenforceable term or provision, the
parties hereto intend that there shall be added as a part of this Letter Agreement a provision as similar in terms to such invalid or unenforceable provision as may be possible and be valid and enforceable. 

 17. Governing Law. This Letter Agreement shall be governed by and construed and
enforced in accordance with the laws of the State of New York, without giving effect to conflicts of law principles that would result in the application of the substantive laws of another jurisdiction. The parties hereto (i) all agree that any
action, proceeding, claim or dispute arising out of, or relating in any way to, this Letter Agreement shall be brought and enforced in the courts of New York City, in the State of New York, and irrevocably submit to such jurisdiction and venue,
which jurisdiction and venue shall be exclusive, and (ii) waive any objection to such exclusive jurisdiction and venue or that such courts represent an inconvenient forum. 

18. Notices. Any notice, consent or request to be given in connection with any of the terms or provisions of this Letter Agreement
shall be in writing and shall be sent by express mail or similar private courier service, by certified mail (return receipt requested), by hand delivery or facsimile transmission.

FORWARD PURCHASE AGREEMENT 

This Forward Purchase Agreement (this “Agreement”) is entered into as of
            , 2021, by and between Lamar Partnering Corporation, a Cayman Islands exempted company (the “Company”), and Lamar Partnering Sponsor LLC, a Delaware limited
liability company (the “Sponsor”). 
 Recitals 

WHEREAS, the Company was incorporated for the purpose of effecting a merger, capital stock exchange, asset acquisition, stock purchase,
reorganization or similar business combination with one or more businesses (a “Business Combination”); 
 WHEREAS, the
Company has filed with the U.S. Securities and Exchange Commission (the “SEC”) a registration statement on Form S-1 (such registration statement, as may be amended from time to time,
including to reflect changes in terms, the “Registration Statement”) for its initial public offering (“IPO”) of 30,000,000 units (or 34,500,000 units in the aggregate if the underwriters exercise their
over-allotment in full) (the “Public Units”) at a price of $10.00 per Public Unit, each comprised of one Class A ordinary share of the Company, par value $0.0001 per share (the “Class A Share(s)”), and one-fourth of one redeemable warrant, where each whole redeemable warrant is exercisable to purchase one Class A Share at an exercise price of $11.50 per share, subject to adjustment (the
“Warrant(s)”); 
 WHEREAS, following the closing of the IPO (the “IPO Closing”), the Company will seek to
identify and consummate a Business Combination; 
 WHEREAS, the parties hereto wish to enter into this Agreement, pursuant to which
substantially concurrently with the closing of the Company’s initial Business Combination (the “Business Combination Closing”), the Company shall issue and sell, and the Sponsor shall purchase, on a private placement basis, up
to an aggregate of 10,000,000 units (the “Forward Purchase Units”) at a price of $10.00 per Forward Purchase Unit, each comprised of one Class B ordinary share of the Company, par value $0.0001 per share (the “Forward
Purchase Shares”), and one-fourth of one redeemable warrant, where each whole redeemable warrant is exercisable to purchase one Class A Share at an exercise price of $11.50 per share, subject to
adjustment (the “Forward Purchase Warrant(s)”); and 
 WHEREAS, at the time of, or prior to, the closing of the IPO, the
Company, the Sponsor and Lamar Media Corp., a Delaware corporation (“LMC”), shall enter into an investor rights agreement (the “Investor Rights Agreement”) pursuant to which the Company will grant certain
registration rights to the Sponsor and LMC relating to the Forward Purchase Units. 
 NOW, THEREFORE, in consideration of the premises,
representations, warranties and the mutual covenants contained in this Agreement, 

 
and for other good and valuable consideration, the receipt, sufficiency and adequacy of which are hereby acknowledged, the parties hereto agree as follows: 

Agreement 

1.    Sale and Purchase. 

(a)    Forward Purchase Units. 

(i)    The Company shall issue and sell to the Sponsor, and the Sponsor shall purchase from the Company, (1) the
number of Forward Purchase Units that is the quotient of (x) the amount of capital committed to the Sponsor and allocated to this Agreement as notified by the Sponsor to the Company no later than five (5) Business Days prior to such time
as any definitive agreement with respect to a Business Combination is executed by the Company (the “Allocation Notice”), which amount shall be no more than $100,000,000 in the Sponsor’s sole discretion, and (y) $10.00 (the
“Number of Forward Purchase Shares”), plus (2) the number of Forward Purchase Warrants which is the product of (x) the number of Forward Purchase Shares as determined by clause (1) and (y) 1/3 (the “Number of Forward
Purchase Warrants”) for an aggregate purchase price of $10.00 multiplied by the number of Forward Purchase Shares issued and sold hereunder (the “FPU Purchase Price”). No fractional Forward Purchase Warrants will be issued.
Each Forward Purchase Warrant and its underlying Class A Share will have the same terms as the Warrants and their underlying Class A Shares to be issued in the IPO. Each Forward Purchase Warrant will be subject to the terms and conditions
of the Warrant Agreement to be entered into between the Company and Continental Stock Transfer & Trust Company, as Warrant Agent, in connection with the IPO. 

(ii)    The Company shall deliver written notice to the Sponsor to purchase the Forward Purchase Units pursuant to
Section 1(a)(i) hereof by delivering notice (the “Company Notice”) to the Sponsor, at least five (5) Business Days before the funding of the FPU Purchase Price, specifying the anticipated date of the Business
Combination Closing and instructions for wiring the FPU Purchase Price to an account designated by the Company, which may be but need not be an interest-bearing account. At least two (2) Business Days before the anticipated date of the Business
Combination Closing specified in such Company Notice (or such later date as the Company and the Sponsor may agree), the Sponsor shall deliver the FPU Purchase Price in cash via wire transfer to the account specified in such Company Notice, to be
held in escrow pending the FPU Closing (as defined below). If the FPU Closing does not occur within five (5) Business Days after the Sponsor delivers the FPU Purchase Price to such account, the Company shall, upon request of the Sponsor, return
to the Sponsor the FPU Purchase Price (and to the extent that there is any interest on the account holding the FPU Purchase Price, such interest shall go the Sponsor), provided that the return of the FPU Purchase Price placed in escrow shall not
terminate this Agreement or otherwise relieve either party of any of its obligations hereunder and the Company may provide a subsequent Company Notice pursuant to this Section 1(a)(ii). For the purposes of this Agreement, “Business
Day” means any day, other than a Saturday or a Sunday, that is neither a legal holiday nor a day on which banking institutions are generally authorized or required by law or regulation to close in the City of New York, New York. 

(iii)    The closing of the sale of the Forward Purchase Units (the “FPU Closing”) shall be held on the
same date and substantially concurrently with the Business Combination Closing (such date being referred to as the “FPU Closing Date”). At the FPU Closing, the Company will issue to the Sponsor the Forward Purchase Shares and
Forward Purchase Warrants. 

  
 2 

 (b)    Delivery of Forward Purchase Units. 

(i)    The Company shall register the Sponsor as the owner of the Forward Purchase Shares and Forward Purchase Warrants
included in the Forward Purchase Units with the Company’s transfer agent by book entry on or promptly after (but in no event more than two (2) Business Days after) the FPU Closing Date. 

(ii)    Each book entry for the Forward Purchase Units shall contain a notation, and each certificate (if any) evidencing
the Forward Purchase Units shall be stamped or otherwise imprinted with a legend, in substantially the following form: 
 “THE
SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED, OR THE SECURITIES LAWS OF ANY STATE OR OTHER JURISDICTION, AND MAY NOT BE TRANSFERRED IN VIOLATION OF SUCH ACT AND LAWS.”

 (c)    Registration Rights. The Sponsor shall have registration rights as set forth in the Investor Rights
Agreement substantially in the form attached as Exhibit 10.2 of the Registration Statement (the “Investor Rights Agreement”). 

2.    Representations and Warranties of the Sponsor. The Sponsor represents and warrants to the Company as
follows, as of the date hereof: 
 (a)    Organization and Power. The Sponsor is duly formed and validly existing
and in good standing in its jurisdiction of incorporation or organization and has all requisite power and authority to carry on its business as presently conducted and as proposed to be conducted. 

(b)    Authorization. The Sponsor has full power and authority to enter into this Agreement. This Agreement, when
executed and delivered by the Sponsor, will constitute the valid and legally binding obligation of the Sponsor, enforceable against the Sponsor in accordance with its terms, except (a) as limited by applicable bankruptcy, insolvency,
reorganization, moratorium, fraudulent conveyance and any other laws of general application affecting enforcement of creditors’ rights generally, (b) as limited by laws relating to the availability of specific performance, injunctive
relief or other equitable remedies, or (c) to the extent the indemnification provisions contained in the Investor Rights Agreement may be limited by applicable federal or state securities laws. 

(c)    Governmental Consents and Filings. No consent, approval, order or authorization of, or registration,
qualification, designation, declaration or filing with, any federal, state or local governmental authority is required on the part of the Sponsor in connection with the execution of this Agreement. 

  
 3 

 (d)    Compliance with Other Instruments. The execution, delivery
and performance by the Sponsor of this Agreement and the consummation by the Sponsor of the transactions contemplated by this Agreement will not result in any violation or default (i) of any provisions of its organizational documents,
(ii) of any instrument, judgment, order, writ or decree to which it is a party or by which it is bound, (iii) under any note, indenture or mortgage to which it is a party or by which it is bound, (iv) under any lease, agreement,
contract or purchase order to which it is a party or by which it is bound or (v) of any provision of federal or state statute, rule or regulation applicable to the Sponsor, in each case (other than clause (i)), which would have a material
adverse effect on the Sponsor or its ability to consummate the transactions contemplated by this Agreement. 

(e)    Purchase Entirely for Own Account. This Agreement is made with the Sponsor in reliance upon the
Sponsor’s representation to the Company, which by the Sponsor’s execution of this Agreement, the Sponsor hereby confirms, that the Forward Purchase Units to be acquired by the Sponsor will be acquired for investment for the Sponsor’s
own account, not as a nominee or agent, and not with a view to the resale or distribution of any part thereof, and that the Sponsor has no present intention of selling, granting any participation in, or otherwise distributing the same in violation
of law. By executing this Agreement, the Sponsor further represents that the Sponsor does not presently have any contract, undertaking, agreement or arrangement with any Person to sell, transfer or grant participations to such Person or to any third
Person, with respect to any of the Forward Purchase Units. For purposes of this Agreement, “Person” means an individual, a limited liability company, a partnership, a joint venture, a corporation, a trust, an unincorporated organization,
any other entity or any government or any department or agency thereof. 
 (f)    Disclosure of Information. The
Sponsor has had an opportunity to discuss the Company’s business, management, financial affairs and the terms and conditions of the offering of the Forward Purchase Units, as well as the terms of the Company’s proposed IPO, with the
Company’s management. 
 (g)    Restricted Securities. The Sponsor understands that the offer and sale of
the Forward Purchase Units have not been registered under the Securities Act of 1933, as amended, and the rules and regulations of the Commission promulgated thereunder (the “Securities Act”), by reason of a specific exemption
from the registration provisions of the Securities Act that depends upon, among other things, the bona fide nature of the investment intent and the accuracy of the Sponsor’s representations as expressed herein. The Sponsor understands that the
Forward Purchase Units are “restricted securities” under applicable U.S. federal and state securities laws and that, pursuant to these laws, the Sponsor must hold the Forward Purchase Units indefinitely unless they are registered with the
SEC and qualified by state authorities, or an exemption from such registration and qualification requirements is available. The Sponsor acknowledges that the Company has no obligation to register or qualify the Forward Purchase Units for resale,
except pursuant to the Investor Rights Agreement. The Sponsor further acknowledges that if an exemption from registration or qualification is available, it may be conditioned on various requirements including, but not limited to, the time and manner
of sale, the holding period for the Forward Purchase Units, and on requirements relating to the Company that are outside of the Sponsor’s control, and which the Company is under no obligation and may not be able to satisfy. The Sponsor
understands that the offering to the Sponsor of the Forward Purchase Units is not, and is not intended to be, part of the IPO, and that the Sponsor will not be able to rely on the protection of Section 11 or Section 12 of the Securities
Act with respect to the Forward Purchase Units.

the parties hereto, and any dispute between the parties (whether grounded in contract, tort, statute, law or equity) shall be governed by, construed in accordance with, and interpreted pursuant to the laws of the State of New York. 

(i)    Jurisdiction. The parties hereto (i) hereby irrevocably and unconditionally submit to the jurisdiction
of the state courts of New York and to the jurisdiction of the United States District Court for the Southern District of New York for the purpose of any suit, action or other proceeding arising out of or based upon this Agreement, (b) agree not
to commence any suit, action or other proceeding arising out of or based upon this Agreement except in state courts of New York or the United States District Court for the Southern District of New York, and (c) hereby waive, and agree not to

This Agreement may not be amended, modified or waived as to any particular provision, except with the written consent of the Company and the Sponsor. No waiver by any party hereto of any default, misrepresentation, or breach of warranty or covenant

 (l)    Severability. The provisions of this Agreement will be deemed severable and the invalidity or
unenforceability of any provision will not affect the validity or enforceability of the other provisions hereof; provided that if any provision of this Agreement, as applied to any party hereto or to any circumstance, is adjudged by a governmental
authority, arbitrator, or mediator not to be enforceable in accordance with its terms, the parties hereto agree that the governmental authority, arbitrator, or mediator making such determination will have the power to modify the provision in a

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 

  
 13 

 
burden of proof will arise favoring or disfavoring any party hereto because of the authorship of any provision of this Agreement. Any reference to any federal, state, local, or foreign law will
be deemed also to refer to law as amended and all rules and regulations promulgated thereunder, unless the context requires otherwise. 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. The word “Business Day” means any calendar day other than Saturday, Sunday, or a day on which banks in New York, New York or Denver, Colorado are
authorized or required to be closed. 
 (o)    Confidentiality. Except as may be required by law, regulation or
applicable stock exchange listing requirements, unless and until the transactions contemplated hereby and the terms hereof are publicly announced or otherwise publicly disclosed by the Company, the parties hereto shall keep confidential and shall
not publicly disclose the existence or terms of this Agreement. 
 (p)    Adjustments. References herein to
numbers of shares, the Class B thereof, and to per share prices, shall be appropriately adjusted to account for any reclassification, exchange, substitution, combination, share sub-division, reverse share
subdivision, or share dividend or other share distribution made on or with respect to the applicable Class B of shares, occurring or effective following the date of this Agreement.
