SECURITIES
SUBSCRIPTION AGREEMENT


 


This
Amended and Restated Securities Subscription Agreement (this “Agreement”) is entered into as of October 9,
2020 (the “Effective Date”) by and between BOC Yellowstone, LLC, a Delaware limited liability company (the
“Subscriber” or “you”), and Yellowstone Acquisition Company, a Delaware corporation (the
“Company”, “we” or “us”).


 


INTRODUCTION


 


WHEREAS,
the Company and Subscriber entered into that certain Securities Subscription Agreement as of August 31, 2020 (the “Original
Agreement”) pursuant to which the Company accepted the offer of Subscriber to purchase 5,750,000 shares of Class B common
stock, $0.0001 par value per share (the “Class B Common Stock”), up to 750,000 of which were subject to forfeiture
by Subscriber if the underwriters of the initial public offering (“IPO”) of units (“Units”)
of the Company did not fully exercise their over-allotment option (the “Over-allotment Option”), and


 


WHEREAS,
the Company and Subscriber have agreed that as a result of a change in the gross proceeds under the offering terms of the registration
statement on Form S-1 (File No. 333 249035) (the “Registration Statement”) and prospectus (the
“Prospectus”) for the IPO of the Company’s Units, the Subscriber shall amend its subscription to purchase
4,312,500 shares (the “Shares”) of Class B Common Stock, up to 562,500 of which shall be subject to forfeiture
(the “Forfeiture Amount”) if the Over-allotment Option is not fully exercised, and


 


WHEREAS,
the Company and Subscriber have further agreed and desire that the Original Agreement be replaced and superseded hereby;


 


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


 


ARTICLE
I


PURCHASE
OF SECURITIES


 


1.01
Purchase of Shares. For the sum of $25,000 (the “Purchase Price”), which the Company acknowledges receiving
in cash, the Company hereby issues the Shares to the Subscriber, and the Subscriber hereby purchases the Shares from the Company,
subject to the Forfeiture Amount, on the terms and subject to the conditions set forth in this Agreement. Concurrently
with the Subscriber’s execution of this Agreement, the Company shall, at its option, deliver to the Subscriber a certificate
registered in the Subscriber’s name representing the shares (the “Original Certificate”), or effect such
delivery in book-entry form.


 


ARTICLE
II

REPRESENTATIONS, WARRANTIES AND AGREEMENTS


 


2.01
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:


 


a)
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.


 






     


     


    

 


b)
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.


 


c)
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 is a legal, valid and binding agreement of the Subscriber,
enforceable against the 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).


 


d)
Experience, Financial Capability and Suitability. The 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. The Subscriber is capable of evaluating the merits and risks of its investment in the Company and has the capacity
to protect its own interests. The 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 (as defined below) or (ii) an exemption from registration
available with respect to such sale. The Subscriber is able to bear the economic risks of an investment in the Shares and to afford
a complete loss of the Subscriber’s investment in the Shares.


 


e)
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, the Subscriber has relied
solely on the Subscriber’s own knowledge and understanding of the Company and its business based upon the Subscriber’s
own due diligence investigation and the information furnished pursuant to this paragraph. The Subscriber understands that no person
has been authorized to give any information or to make any representations which were not furnished pursuant to this Article II and
the 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.


 


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


 






    2


     


    

 


g)
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. 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 under the Securities Act.


 


h)
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. The Subscriber understands the Shares will be “restricted securities”
within the meaning of Rule 144(a)(3) under the Securities Act, and the Subscriber understands that the certificates or book-entries
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. The 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, the
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. The 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.


 


i)
No Governmental Consents. No governmental, administrative or other third party consents or approvals are required, necessary
or appropriate on the part of the Subscriber in connection with the transactions contemplated by this Agreement.


 


2.02
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:


 


a)
Organization and Corporate Power. The Company is a corporation duly organized, validly existing and in good standing under
the laws of the State of Delaware. The Company possesses all requisite corporate power and authority necessary to carry out the
transactions contemplated by this Agreement.


 


b)
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 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, except,
with respect to clauses (ii) and (iii) above, where such violation, conflict or default would not reasonably be expected to have
a material adverse effect on the financial condition, operating results or assets of the Company.


 


c)
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 (i) transfer restrictions hereunder and other agreements to which the Shares may be subject which have been notified
to the Subscriber in writing, (ii) transfer restrictions under federal and state securities laws, and (iii) liens, claims or encumbrances
imposed due to the actions of the Subscriber.


 






    3


     


    

 


d)
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.


 


ARTICLE
III

FORFEITURE OF SHARES


 


3.01
Partial or No Exercise of the Over-allotment Option. In the event the Over-allotment Option granted to the underwriters
of the IPO is not exercised in full, the Subscriber acknowledges and agrees that it (or, if applicable, it and any transferees
of Shares) shall forfeit any and all rights to such number of Shares (up to an aggregate of 562,500 Shares and pro rata based
upon the percentage of the Over-allotment Option exercised) such that immediately following such forfeiture, the Subscriber (and
all other initial stockholders prior to the IPO, if any) will own an aggregate number of Shares, not including any shares of the
Company’s Class A common stock, par value $0.0001 per share (the “Class A Common Stock” and, together
with the Class B Common Stock, the “Common Stock”), issuable upon exercise of any warrants or any shares of
Class A Common Stock purchased by Subscriber in the IPO or in the aftermarket, equal to twenty percent (20%) of the issued and
outstanding shares of Common Stock immediately following the IPO.


 


3.02
Termination of Rights as Stockholder. If any of the Shares are forfeited in accordance with this Article III,
then after such time the Subscriber (or successor in interest), shall no longer have any rights as a holder of such forfeited
Shares, and the Company shall take such action as is appropriate to cancel such forfeited Shares.


 


3.03
Share Certificates. In the event an adjustment to the Original Certificate,
if any, is required pursuant to this Article III, 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 the Subscriber
of such adjustment, following which a new certificate (the “New Certificate”), if any, shall be issued in such
amount representing the adjusted number of Shares held by the Subscriber. The New Certificate, if any, shall be returned to the
Subscriber as soon as practicable. Any such adjustment for any uncertificated securities held by the Subscriber shall be made
in book-entry form.


 


ARTICLE
IV

WAIVER OF LIQUIDATION DISTRIBUTIONS; REDEMPTION RIGHTS


 


4.01
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 any shares of Class A Common Stock
in the IPO or in the aftermarket, any such shares 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
V

RESTRICTIONS ON TRANSFER


 


5.01
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 the Subscriber and the
Company, the 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.


 


5.02
Lock-up. The Subscriber acknowledges that the Securities will be subject to lock-up
provisions (the “Lock-up”) contained in the Insider Letter.


 


5.03
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 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 A LOCKUP AND MAY NOT BE OFFERED, SOLD, TRANSFERRED, PLEDGED OR OTHERWISE
DISPOSED DURING THE TERM OF THE LOCKUP.”


 


5.04
Additional Shares or Substituted Securities. In the event of the declaration of a share dividend, the declaration of an
extraordinary dividend payable in a form other than Shares, a spin-off, a share split, 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 Article V or into which such Shares thereby become convertible shall immediately be subject to this Article V and Article III.
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 Article V and Article III.


 


5.05
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 in connection with the closing
of the IPO (the “Registration Rights Agreement”).

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

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.


 


6.03
Entire Agreement. This Agreement, together with the Insider Letter and the Registration Rights Agreement, each 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.


 


6.04
Modifications and Amendments. The terms and provisions of this Agreement may be modified or amended only by written agreement
executed by all parties hereto.


 


6.05
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.


 


6.06
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.


 


6.07
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.


 


6.08
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 Delaware applicable to contracts wholly performed within the borders of such state, without giving
effect to the conflict of law principles thereof.


 


6.09
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


     


    

 


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.


 






    7


     


    

 


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.

by the Company.
