Re:          Securities
Subscription Agreement


 


Ladies and Gentlemen:


 


This agreement (the “Agreement”)
is entered into on June 9, 2021 by and between Western Acquisition Ventures Sponsor LLC, a Delaware limited liability company (the
 “Subscriber” or “you”), and Western Acquisition Ventures Corp., a Delaware corporation (the “Company”,
 “we” or “us”). Pursuant to the terms hereof, the Company hereby accepts the offer the Subscriber
has made to purchase 4,312,500 shares (the “Shares”) of our Common Stock, $0.0001 par value per share (the “Founder
Shares”), up to 562,500 of which are subject to forfeiture by you if the underwriters of the initial public offering (“IPO”)
of units of the Company (the “Units”) do not fully exercise their over-allotment option (the “Over-allotment
Option”). The Company and the Subscriber’s agreements regarding such Shares are as follows:


 


1.            Purchase
of Shares. For the sum of $25,000.00, which the Company acknowledges receiving in immediately
available funds, the Company hereby issues the Shares to the Subscriber, and the Subscriber hereby purchases the Shares from the Company,
subject to forfeiture, 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.


 


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 (a) the formation and governing documents of the Subscriber; (b) any
agreement, indenture or instrument to which the Subscriber is a party; or (c) 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        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 Company, this Agreement is 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.


 


(a)           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 of 1933, as amended (the “Securities Act”), and therefore the Shares 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.


 


(b)           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
that 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 promulgated under 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 promulgated under
the Securities Act or similar exemptions under state law.


 


2.1.7        Investment
Purposes. The Subscriber is purchasing the Shares solely for investment purposes, for the Subscriber’s own account, and not
for the account or benefit of any other person, and not with a view towards the distribution or dissemination thereof. 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(c) of
Regulation D promulgated under the Securities Act.


 






     - 2 -


     


    

 


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
section (a)(3) of Rule 144 promulgated under the Securities Act (“Rule 144”), and Subscriber understands
that the Certificates (as defined in Section 3.3) 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 (a) registration under the Securities Act covering such offer,
resale, pledge or other transaction; or (b) 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, Subscriber may not be able to rely on Rule 144
promulgated under the Securities Act with respect to 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, necessary or appropriate
on the part of Subscriber in connection with the transactions contemplated by this Agreement.


 


2.2           Company’s
Representations, Warranties and Agreements. To induce the Subscriber to purchase the Shares, the Company hereby represents and warrants
to the Subscriber and agrees with the Subscriber as follows:


 


2.2.1        Organization
and Corporate Power. The Company is a Delaware corporation and is qualified to do business in every jurisdiction in which the failure
to so qualify would reasonably be expected to have a material adverse effect on the financial condition, operating results or assets of
the Company. The Company possesses all requisite corporate power and authority necessary to carry out the transactions contemplated by
this Agreement. Upon execution and delivery by Subscriber, this Agreement is a legal, valid and binding agreement, enforceable against
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 (a) the certificate of incorporation or by-laws of the Company;
(b) any agreement, indenture or instrument to which the Company is a party; or (c) 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.


 






     - 3 -


     


    

 


2.2.3        Title
to Securities. Upon issuance in accordance with, and payment pursuant to, the terms hereof, the Shares will be duly and validly issued,
fully paid and nonassessable. Upon issuance in accordance with, and payment pursuant to, the terms hereof, the Subscriber will have or
receive good title to the Shares, free and clear of all liens, claims and encumbrances of any kind, other than (a) transfer restrictions
hereunder and other agreements to which the Shares may be subject which have been notified to the Subscriber in writing; (b) transfer
restrictions under federal and state securities laws; and (c) liens, claims or encumbrances imposed due to the actions of the Subscriber.


 


2.2.4        No
Adverse Actions. There are no actions, suits, investigations or proceedings pending, threatened against or affecting the Company that:
(a) seek to restrain, enjoin, prevent the consummation of or otherwise affect the transactions contemplated by this Agreement or
(b) question the validity or legality of any transactions or seeks to recover damages or to obtain other relief in connection with
any transactions.


 


3.             Forfeiture
of Shares.


 


3.1           Partial
or No Exercise of the Over-allotment Option. In the event the Over-allotment Option granted to the underwriters of the IPO is not
exercised in full, the Subscriber acknowledges and agrees that it (or, if applicable, it and any transferees of the Shares (such transferees,
the “Initial Stockholders”)) shall forfeit any and all rights to such number of Shares (up to an aggregate of 562,500
Shares, 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 issuable upon exercise of any warrants or any shares of common stock, par value $0.0001 per share, of the Company (together with
the Founder Shares, the “Common Stock”) purchased by Subscriber or any other Initial Stockholder in the IPO or in the
aftermarket) equal to 20% of the issued and outstanding Shares immediately following the IPO.


 


3.2           Termination
of Rights as Stockholder. If any of the Shares are forfeited in accordance with this Section 3, then, after such time,
the Subscriber (or Initial Stockholder or other 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.


 


3.3           Share
Certificates. In the event an adjustment to the original certificates representing the Shares
(the “Original Certificates”), if any, is required as a result of the forfeiture set forth in Section 3.1
above, then the Subscriber shall return such Original Certificates to the Company or its designated agent as soon as practicable upon
its receipt of Notice (as defined in Section 6.2) from the Company advising Subscriber of such adjustment, following which
a new certificate representing the Shares (the “New Certificate” and together with the Original Certificates, the “Certificates”),
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.


 






     - 4 -


     


    

 


4.             Waiver
of Liquidation Distributions; Redemption Rights. In connection with the Shares purchased pursuant
to this Agreement, the Subscriber hereby waives any and all right, title, interest or claim of any kind in or to any distributions by
the Company from the trust account that 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 Units in the IPO or shares of Common Stock in the aftermarket, any additional shares of Common Stock included
in the Units or shares of Common Stock so purchased shall be eligible to receive any liquidating distributions by the Company; provided,
however, that 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.


 


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”) by and between Subscriber and the Company to be dated as of the closing of the IPO, 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 offer and sale of 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 (i) under the Securities
Act and the rules promulgated thereunder by the Securities and Exchange Commission and (ii) with respect to all applicable state
securities laws.


 


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


 


5.3           Restrictive
Legends. Any Certificates shall have endorsed thereon legends substantially as follows:


 


“THE OFFER AND SALE OF 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 COVERING SUCH OFFER, SALE, TRANSFER, PLEDGE OR OTHER DISPOSAL 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.”


 


5.4           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 Common Stock, a spin-off, a share split, an adjustment in conversion ratio, a recapitalization, or a similar
transaction affecting the Company’s outstanding shares of Common Stock without receipt of consideration, any new, substituted or
additional securities or other property, which are by reason of such transaction distributed with respect to any Shares subject to this
Section 5 or into which such Shares thereby become convertible shall immediately be subject to this Section 5
and Section 3. Appropriate adjustments to reflect the distribution of such securities or property shall be made to the number
or class of Shares subject to this Section 5 and Section 3.


 






     - 5 -


     


    

 


5.5           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 the offer and sale of the Shares is registered
under the Securities Act pursuant to that certain registration rights agreement to be dated as of the closing of the IPO and to be made
by and among Subscriber, the Company, and the other parties thereto (the “Registration Rights Agreement”).


 


6.             Other

be in writing and addressed to the parties at the addresses set forth on the first page of this Agreement (or to such other address
that may be designated by the receiving party from time to time in accordance with this Section 6.2). A Notice shall be deemed
to have been given (a) when delivered by hand (with written confirmation of receipt); (b) when received by the addressee if

if sent during normal business hours of the recipient, and on the next business day if sent after normal business hours of the recipient;
or (d) on the third day after the date mailed, by certified or registered mail (in each case, return receipt requested, postage pre-paid).

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.

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

     - 6 -


     


    

 


6.7       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.


 


6.8           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.


 


6.9           Waivers
and Consents. No waiver by any party of any of the provisions hereof shall be effective unless explicitly set forth in writing and
signed by the party so waiving. No waiver by any party shall operate or be construed as a waiver in respect of any failure, breach, or
default not expressly identified by such written waiver, whether of a similar or different character, and whether occurring before or
after that waiver. No failure to exercise, or delay in exercising, any right, remedy, power, or privilege arising from this Agreement
shall operate or be construed as a waiver thereof; nor shall any single or partial exercise of any right, remedy, power, or privilege
hereunder preclude any other or further exercise thereof or the exercise of any other right, remedy, power, or privilege. No Notice on
a party not expressly required under this Agreement shall entitle the party receiving such Notice to any other or further Notice in similar
or other circumstances or constitute a waiver of the rights of the party giving such Notice to any other or further action in any circumstances
without such Notice.


 


6.10         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.


 


6.11         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.


 


6.12         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.


 






     - 7 -


     


    

 


6.13         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 any 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.


 


6.14         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.


 


6.15         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 Tender of Shares. The Subscriber agrees to vote the Shares in favor of an initial business
combination that the Company negotiates and submits for approval to the Company’s stockholders and the Subscriber shall not seek
redemption 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 stockholders in connection with an initial business combination negotiated by the Company.


 


8.             Indemnification.
Each party shall indemnify the other against any loss, cost or damages (including reasonable attorney’s fees and expenses) incurred
as a result of such party’s breach of any representation, warranty, covenant or agreement in this Agreement.
