	 	RE:	 Securities Subscription Agreement 

Ladies and Gentlemen: 
 This agreement (the
“Agreement”) is entered into on February 16, 2021 by and between Cascadia Acquisition Sponsor LLC, a Delaware limited liability company (the “Subscriber” or “you”), and Cascadia Acquisition
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 of Class B
common stock, $0.0001 par value per share (the “Shares”), up to 562,500 of which are subject to forfeiture by you if the underwriters of the initial public offering (“IPO”) of units (“Units”) of the
Company, do not fully exercise their over-allotment option (the “Over-allotment Option”). The Company and the Subscriber’s agreements regarding such Shares are as follows: 

1. Purchase of Securities. 
 1.1.
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 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 (i) the formation and governing documents of the Subscriber, (ii) any agreement, indenture or instrument to which the Subscriber is a party or
(iii) any law, statute, rule or regulation to which the Subscriber is subject, or any agreement, order, judgment or decree to which the Subscriber is subject. 

2.1.3. 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 Subscriber,
enforceable against Subscriber in accordance with its terms, except as such enforceability may be limited by applicable bankruptcy, insolvency, fraudulent conveyance or similar laws affecting the enforcement of creditors’ rights generally and
subject to general principles of equity (regardless of whether enforcement is sought in a proceeding at law or in equity). 
 2.1.4.
Experience, Financial Capability and Suitability. Subscriber is: (i) sophisticated in financial matters and is able to evaluate the risks and benefits of the investment in the Shares and (ii) able to bear the economic risk of its
investment in the Shares for an indefinite period of time because the Shares have not been registered under the Securities Act (as defined below) and therefore cannot be sold unless subsequently registered under the Securities Act or an exemption
from such registration is available. Subscriber is capable of evaluating the merits and risks of its investment in the Company and has the capacity to protect its own interests. Subscriber must bear the economic risk of this investment until the
Shares are sold pursuant to: (i) an effective registration statement under the Securities Act or (ii) an exemption from registration available with respect to such sale. Subscriber is able to bear the economic risks of an investment in the
Shares and to afford a complete loss of Subscriber’s investment in the Shares. 
 2.1.5. Access to Information; Independent
Investigation. Prior to the execution of this Agreement, the Subscriber has had the opportunity to ask questions of and receive answers from representatives of the Company concerning an investment in the Company, as well as the finances,
operations, business and prospects of the 

 
Company, and the opportunity to obtain additional information to verify the accuracy of all information so obtained. In determining whether to make this investment, Subscriber has relied solely
on Subscriber’s own knowledge and understanding of the Company and its business based upon Subscriber’s own due diligence investigation and the information furnished pursuant to this paragraph. Subscriber understands that no person has
been authorized to give any information or to make any representations which were not furnished pursuant to this Section 2 and Subscriber has not relied on any other representations or information in making its investment decision, whether
written or oral, relating to the Company, its operations and/or its prospects. 
 2.1.6. Regulation D Offering. Subscriber represents
that it is an “accredited investor” as such term is defined in Rule 501(a) of Regulation D under the Securities Act of 1933, as amended (the “Securities Act”) and acknowledges the sale contemplated hereby is being made in
reliance on a private placement exemption to “accredited investors” within the meaning of Section 501(a) of Regulation D under the Securities Act or similar exemptions under 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 under the Securities Act. 
 2.1.8. Restrictions on Transfer; Shell Company. Subscriber
understands the Shares are being offered in a transaction not involving a public offering within the meaning of the Securities Act. Subscriber understands the Shares will be “restricted securities” within the meaning of Rule 144(a)(3)
under the Securities Act, and Subscriber understands that the certificates 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. 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 reasonably satisfactory to the Company. Absent registration or an
exemption, the Subscriber agrees not to resell the Shares. Subscriber further acknowledges that because the Company is a shell company, Rule 144 may not be available to the Subscriber for the resale of the Shares until one year following
consummation of the initial business combination of the Company, despite technical compliance with the requirements of Rule 144 and the release or waiver of any contractual transfer restrictions. 

2.1.9. No Governmental Consents. No governmental, administrative or other third party consents or approvals are required, necessary or
appropriate on the part of Subscriber in connection with the transactions contemplated by this Agreement. 
 2.2. Company’s
Representations, Warranties and Agreements. To induce the Subscriber to purchase the Shares, the Company hereby represents and warrants to the Subscriber and agrees with the Subscriber as follows: 

2.2.1. Organization and Corporate Power. The Company is a Delaware corporation and is qualified to do business in every jurisdiction in
which the failure to so qualify would reasonably be expected to have a material adverse effect on the financial condition, operating results or assets of the Company. The Company possesses all requisite corporate power and authority necessary to
carry out the transactions contemplated by this Agreement. 
 2.2.2. No Conflicts. The execution, delivery and performance of this
Agreement and the consummation by the Company of the transactions contemplated hereby do not violate, conflict with or constitute a default under (i) the Certificate of Incorporation or By Laws of the Company, (ii) any agreement, indenture
or instrument to which the Company is a party or (iii) any law, statute, rule or regulation to which the Company is subject, or any agreement, order, judgment or decree to which the Company is subject. 

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

 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 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 Shares
issuable upon exercise of any warrants or any Common Stock purchased by Subscriber in the IPO or in the aftermarket equal to 20% of the issued and outstanding 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 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, if any, is required pursuant to this Section 3,
then the Subscriber shall return such Original Certificates to the Company or its designated agent as soon as practicable upon its receipt of notice from the Company advising Subscriber of such adjustment, following which a new certificate (the
“New Certificate”), 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. Waiver of Liquidation Distributions;
Redemption Rights. In connection with the Shares purchased pursuant to this Agreement, the Subscriber hereby waives any and all right, title, interest or claim of any kind in or to any distributions by the Company from the trust account which
will be established for the benefit of the Company’s public stockholders and into which substantially all of the proceeds of the IPO will be deposited (the “Trust Account”), in the event of a liquidation of the Company upon the
Company’s failure to timely complete an initial business combination. For purposes of clarity, in the event the Subscriber purchases Shares in the IPO or in the aftermarket, any additional 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. 

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

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

5.3. 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.” 
 5.4. 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 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 Section 5 or into which such Shares thereby become convertible shall immediately be subject to this Section 5 and Section 3. Appropriate adjustments to reflect the distribution of such
securities or property shall be made to the number and/or class of Shares subject to this Section 5 and Section 3. 

 5.5. 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 they are registered pursuant to a registration rights agreement to be entered into with the
Company prior to the closing of the IPO. 
 6. Other Agreements. 

6.1. Further Assurances. Subscriber agrees to execute such further instruments and to take such further action as may reasonably be
necessary to carry out the intent of this Agreement. 
 6.2. Notices. All notices, statements or other documents which are required
or contemplated by this Agreement shall be: (i) in writing and delivered personally or sent by first class registered or certified mail, overnight courier service or facsimile or electronic transmission to the address designated in writing,
(ii) by facsimile to the number most recently provided to such party or such other address or fax number as may be designated in writing by such party and (iii) by electronic mail, to the electronic mail address most recently provided to
such party or such other electronic mail address as may be designated in writing by such party. Any notice or other communication so transmitted shall be deemed to have been given on the day of delivery, if delivered personally, on the business day
following receipt of written confirmation, if sent by facsimile or electronic transmission, one (1) business day after delivery to an overnight courier service or five (5) days after mailing if sent by mail. 

6.3. Entire Agreement. This Agreement, together with 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. 
 6.4.
Modifications and Amendments. The terms and provisions of this Agreement may be modified or amended only by written agreement executed by all parties hereto. 

6.5. Waivers and Consents. The terms and provisions of this Agreement may be waived, or consent for the departure therefrom granted,
only by a written document executed by the party entitled to the benefits of such terms or provisions. No such waiver or consent shall be deemed to be or shall constitute a waiver or consent with respect to any other terms or provisions of this
Agreement, whether or not similar. Each such waiver or consent shall be effective only in the specific instance and for the purpose for which it was given, and shall not constitute a continuing waiver or consent. 

6.6. Assignment. The rights and obligations under this Agreement may not be assigned by either party hereto without the prior written
consent of the other party. 
 6.7. Benefit. All statements, representations, warranties, covenants and agreements in this Agreement
shall be binding on the parties hereto and shall inure to the benefit of the respective successors and permitted assigns of each party hereto. Nothing in this Agreement shall be construed to create any rights or obligations except among the parties
hereto, and no person or entity shall be regarded as a third-party beneficiary of this Agreement. 
 6.8. Governing Law. This
Agreement and the rights and obligations of the parties hereunder shall be construed in accordance with and governed by the laws of New York applicable to contracts wholly performed within the borders of such state, without giving effect to the
conflict of law principles thereof. 
 6.9. Severability. In the event that any court of competent jurisdiction shall determine that
any provision, or any portion thereof, contained in this Agreement shall be unreasonable or unenforceable in any respect, then such provision shall be deemed limited to the extent that such court deems it reasonable and enforceable, and as so
limited shall remain in full force and effect. In the event that such court shall deem any such provision, or portion thereof, wholly unenforceable, the remaining provisions of this Agreement shall nevertheless remain in full force and effect. 

6.10. No Waiver of Rights, Powers and Remedies. No failure or delay by a party hereto in exercising any right, power or remedy under
this Agreement, and no course of dealing between the parties hereto, shall operate as a waiver of any such right, power or remedy of such party. No single or partial exercise of any right, power or remedy under this Agreement by a party hereto, nor
any abandonment or discontinuance of steps to enforce any such right, power or remedy, shall preclude such party from any other or further exercise thereof or the exercise of any other right, power or remedy hereunder. The election of any remedy by
a party hereto shall not constitute a waiver of the right of such party to pursue other available remedies. No notice to or demand on a party not expressly required under this Agreement shall entitle the party receiving such notice or demand to any
other or further notice or demand in similar or other circumstances or constitute a waiver of the rights of the party giving such notice or demand to any other or further action in any circumstances without such notice or demand. 

 6.11. Survival of Representations and Warranties. All representations and warranties
made by the parties hereto in this Agreement or in any other agreement, certificate or instrument provided for or contemplated hereby, shall survive the execution and delivery hereof and any investigations made by or on behalf of the parties. 

6.12. No Broker or Finder. Each of the parties hereto represents and warrants to the other that no broker, finder or other financial
consultant has acted on its behalf in connection with this Agreement or the transactions contemplated hereby in such a way as to create any liability on the other. Each of the parties hereto agrees to indemnify and save the other harmless from any
claim or demand for commission or other compensation by any broker, finder, financial consultant or similar agent claiming to have been employed by or on behalf of such party and to bear the cost of legal expenses incurred in defending against any
such claim. 
 6.13. Headings and Captions. The headings and captions of the various subdivisions of this Agreement are for
convenience of reference only and shall in no way modify or affect the meaning or construction of any of the terms or provisions hereof. 

6.14. Counterparts. This Agreement may be executed in one or more counterparts, all of which when taken together shall be considered
one and the same agreement and shall become effective when counterparts have been signed by each party and delivered to the other party, it being understood that both parties need not sign the same counterpart. In the event that any signature is
delivered by facsimile transmission or any other form of electronic delivery, such signature shall create a valid and binding obligation of the party executing (or on whose behalf such signature is executed) with the same force and effect as if such
signature page were an original thereof. 
 6.15. Construction. The parties hereto have participated jointly in the negotiation and
drafting of this Agreement. If an ambiguity or question of intent or interpretation arises, this Agreement will be construed as if drafted jointly by the parties hereto and no presumption or burden of proof will arise favoring or disfavoring any
party hereto because of the authorship of any provision of this Agreement. The words “include,” “includes,” and “including” will be deemed to be followed by “without limitation.”
Pronouns in masculine, feminine, and neuter genders will be construed to include any other gender, and words in the singular form will be construed to include the plural and vice versa, unless the context otherwise requires. The words “this
Agreement,” “herein,” “hereof,” “hereby,” “hereunder,” and words of similar import refer to this Agreement as a whole and not to any particular subdivision unless expressly
so limited. The parties hereto intend that each representation, warranty, and covenant contained herein will have independent significance. If any party hereto has breached any representation, warranty, or covenant contained herein in any respect,
the fact that there exists another representation, warranty or covenant relating to the same subject matter (regardless of the relative levels of specificity) which such party hereto has not breached will not detract from or mitigate the fact that
such party hereto is in breach of the first representation, warranty, or covenant. 
 6.16. Mutual Drafting. This Agreement is the
joint product of the Subscriber and the Company and each provision hereof has been subject to the mutual consultation, negotiation and agreement of such parties and shall not be construed for or against any party hereto. 

7. Voting and Tender of Shares. Subscriber agrees to vote the Shares in favor of an initial business combination that the Company negotiates and
submits for approval to the Company’s stockholders and 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.

Re: Support Agreement 
 Ladies and Gentlemen:

 1. This letter agreement by and between Cascadia Acquisition Corp. (the “Company”) and Cascadia Capital Holdings, LLC
(“Cascadia Capital”), dated as of the date hereof, will confirm our agreement that, commencing on the date the securities of the Company are first listed on the Nasdaq Capital Market (the “Listing Date”), pursuant to a
Registration Statement on Form S-1 and prospectus filed with the U.S. Securities and Exchange Commission (the “Registration Statement”) and continuing until the earlier of the consummation by the
Company of an initial business combination or the Company’s liquidation (in each case as described in the Registration Statement) (such earlier date hereinafter referred to as the “Termination Date”): 

(i) Cascadia Capital shall make available, or cause to be made available, to the Company, at 1000 2nd Avenue, Suite 1200, Seattle, WA 98104
(or any successor location of Cascadia Capital), certain office space and secretarial and administrative services as may be reasonably required by the Company; and 

(ii) Cascadia Capital shall make available certain corporate development and other operational support, including accounting and legal
services, as may be reasonably required by the Company (the services set forth in clauses (i) and (ii) are referred to herein as, the “Services”). 

In exchange therefor, the Company shall pay Cascadia Capital the sum of $15,000 per month on the Listing Date and continuing monthly
thereafter until the Termination Date. 
 2. We are an independent contractor (and we are expressly not acting as a fiduciary) with the
contractual duties described herein owing only to the Company. Since we will be acting on the Company’s behalf, the Company and we agree to the indemnity and other provisions set forth in Annex A. The Company’s obligations
set forth therein shall be in addition to any rights that any Indemnified Person may have at common law or otherwise. Other than the Indemnified Persons, there are no third-party beneficiaries of this agreement. 

3. Either of us may terminate this agreement at any time, with or without cause, on written notice. In the event of any termination, we
will continue to be entitled to the fees that became payable hereunder prior to termination. Annex A and Sections 2 through 6 shall remain in full force and effect after the completion or termination of this agreement. 

4. Cascadia Capital is an independent investment bank which is engaged in a range of investment banking activities. Certain affiliates of
Cascadia Capital are engaged in asset management and other activities for their own account and otherwise. Cascadia Capital and its affiliates may have interests that differ from the Company’s interests. Cascadia Capital and its affiliates have
no duty to disclose to the Company, or use for the Company’s benefit, any information acquired in the course of providing services to any other party, engaging in any transaction or carrying on any other businesses. Cascadia Capital’s
employees, officers, partners and affiliates may at any time own the Company’s securities or those of any other entity involved in any transaction contemplated by this agreement. Cascadia Capital recognizes its obligations under applicable
securities laws in connection with the purchase and sale of such securities. The provision of the Services by Cascadia Capital to the Company as set forth herein or the entry into this agreement by Cascadia Capital with the Company shall not
restrict or prevent Cascadia Capital from acting as a financial advisor, placement agent or investment banker to any other party, including without limitation, (i) to a party that is the counterparty in an initial business combination
contemplated or to be consummated by the Company or (ii) another special purpose acquisition company evaluating the same or similar initial business combination as the Company. 

 5. Cascadia Capital hereby irrevocably waives any and all right, title, interest, causes of
action and claims of any kind as a result of, or arising out of, this agreement (each, a “Claim”) in or to, and any and all right to seek payment of any amounts due to it out of, the trust account established for the benefit of the public
stockholders of the Company and into which substantially all of the proceeds of the Company’s initial public offering will be deposited (the “Trust Account”) as a result of, or arising out of, this agreement, and hereby irrevocably
waives any Claim it may have in the future, which Claim would reduce, encumber or otherwise adversely affect the Trust Account or any monies or other assets in the Trust Account, and further agrees not to seek recourse, reimbursement, payment or
satisfaction of any Claim against the Trust Account or any monies or other assets in the Trust Account for any reason whatsoever. 
 6. This
agreement and any disputes or claims that may arise out of this agreement shall be governed by and construed in accordance with the internal laws of the State of Washington, and this agreement embodies the entire agreement and supersedes any prior
written or oral agreement relating to the subject matter hereof, and may only be amended or waived in writing signed by both the Company and us. If any part of this agreement is judicially determined to be unenforceable, it shall be interpreted to
the fullest extent enforceable so as to give the closest meaning to its intent and the remainder of this agreement shall continue in full force and effect. Any proceeding arising out of this agreement shall be heard exclusively in a Washington state
or federal court sitting in the city of Seattle and county of King County, to whose jurisdiction and forum Cascadia Capital and the Company irrevocably submit. The Company also irrevocably consents to the service of process in any such proceeding by
mail to the Company’s address set forth above. This agreement may be executed in two or more counterparts, each of which shall be deemed an original, but all of which shall constitute one and the same agreement. This agreement shall be binding
upon the Company and us and its and our respective successors and assigns. WE AND THE COMPANY (ON ITS OWN BEHALF AND, TO THE EXTENT PERMITTED BY APPLICABLE LAW, ON BEHALF OF ITS SECURITY HOLDERS) WAIVE ANY RIGHT TO TRIAL BY JURY WITH RESPECT TO ANY
PROCEEDING ARISING OUT OF THIS AGREEMENT.

 ANNEX A 

In the event that Cascadia Capital Holdings, LLC or any of its or its affiliates’ respective current or former directors, officers, partners, managers,
agents, representatives or employees (including any person controlling us or any of our affiliates) (collectively, “Indemnified Persons”) becomes involved in any capacity in any actual or threatened action, claim, suit, investigation or
proceeding (an “Action”) arising out of, related to or in connection with this agreement or any matter referred to herein, the Company will reimburse such Indemnified Person for the reasonable out-of-pocket costs and expenses (including counsel fees) of investigating, preparing for and responding to such Action or enforcing this agreement, as they are incurred. The Company will also indemnify and
hold harmless any Indemnified Person from and against, and the Company agrees that no Indemnified Person shall have any liability to the Company or its affiliates, or their respective owners, directors, officers, employees, security holders or
creditors for, any losses, claims, damages or liabilities (collectively, “Losses”) (A) related to or arising out of oral or written statements or omissions made or information provided by the Company or its agents or (B) otherwise
arising out of, related to or in connection with this agreement or our performance thereof, except that this clause (B) shall not apply to Losses that are finally judicially determined to have resulted primarily from the bad faith or gross
negligence of such Indemnified Person. 
 If such indemnification or limitation on liability are for any reason not available or insufficient to hold an
Indemnified Person harmless, the Company agrees to contribute to the Losses in such proportion as is appropriate to reflect the relative benefits received (or anticipated to be received) by the Company, on the one hand, and by us, on the other hand,
with respect to this agreement or, if such allocation is judicially determined to be unavailable, in such proportion as is appropriate to reflect the relative benefits and relative fault of the Company on the one hand and of us on the other hand,
and any other equitable considerations; provided, however, that, to the extent permitted by applicable law, in no event shall the Indemnified Persons be responsible for amounts that exceed the fees actually received by us from the Company in
connection with this agreement. Relative benefits to the Company, on the one hand, and us, on the other hand, with respect to this agreement shall be deemed to be in the same proportion as (i) the total value paid or proposed to be paid or
received or proposed to be received by the Company or its security holders, as the case may be, pursuant to the Transaction(s), whether or not consummated, bears to (ii) the fees actually received by us in connection with this agreement. 

The Company will not, without our prior written consent (not to be unreasonably withheld), settle, compromise, consent to the entry of any judgment in or
otherwise seek to terminate (a “Settlement”) any Action in respect of which indemnification is or may be sought hereunder (whether or not an Indemnified Person is a party thereto) unless such Settlement includes a release of each
Indemnified Person from any Losses arising out of such Action. The Company will not permit any such Settlement to include a statement as to, or an admission of, fault or culpability by or on behalf of an Indemnified Person without such Indemnified
Person’s prior written consent. No Indemnified Person seeking indemnification, reimbursement or contribution under this agreement will, without the Company’s prior written consent (not to be unreasonably withheld), agree to the Settlement
of any Action.
