For purposes of this Subscription Agreement, a “Company Material Adverse Effect” means an event, change, development, occurrence, condition or effect with respect to the Company and its subsidiaries, taken together as a whole (on a consolidated basis), that, individually or in the aggregate, would reasonably be expected to have a material adverse effect on (i) the business, financial condition or results of operations of the Company and its subsidiaries, taken together as a whole (on a consolidated basis) or (ii) the Company’s ability to consummate the transactions contemplated hereby, including the issuance and sale of the Subscribed Shares.

b.    The Subscribed Shares have been duly authorized and, when issued and delivered to Subscriber against full payment therefor in accordance with the terms of this Subscription Agreement, will be validly issued, fully paid and non-assessable and will not have been issued in violation of any preemptive rights created under the Company’s organizational documents or the laws of its jurisdiction of incorporation.

c.    This Subscription Agreement has been duly executed and delivered by the Company, and assuming the due authorization, execution and delivery of the same by Subscriber, this Subscription Agreement shall constitute the valid and legally binding obligation of the Company, enforceable against the Company in accordance with its terms, except as such enforceability may be limited by bankruptcy, insolvency, reorganization, moratorium and similar laws affecting creditors generally and by the availability of equitable remedies.

d.    The execution and delivery of this Subscription Agreement, the issuance and sale of the Subscribed Shares and the compliance by the Company with all of the provisions of this Subscription Agreement and the consummation of the transactions contemplated herein will not conflict with or result in a breach or violation of any of the terms or provisions of, or constitute a default under, or result in the creation or imposition of any lien, charge or encumbrance upon any of the property or assets of the Company pursuant to the terms of (i) any indenture, mortgage, deed of trust, loan agreement, lease, license or other agreement or instrument to which the Company is a party or by which the Company is bound or to which any of the property or assets of the Company is subject; (ii) the organizational documents of the Company; or (iii) any statute or any judgment, order, rule or regulation of any court or governmental agency or body, domestic or foreign, having jurisdiction over the Company or any of its properties that, in the case of clauses (i) and (iii), would reasonably be expected to have a Company Material Adverse Effect.

e.    Assuming the accuracy of the representations and warranties of the Subscriber, the Company is not required to obtain any consent, waiver, authorization or order of, give any notice to, or make any filing or registration with, any court or other federal, state, local or other governmental authority, self-regulatory organization (including The New York Stock Exchange (“NYSE”)) or other person in connection with the execution, delivery and performance of this Subscription Agreement (including, without limitation, the issuance of the Subscribed Shares), other than (i) filings required by applicable state securities laws, the filing of, (ii) the Registration Statement pursuant to Section 6 below, (iii) the filing of a Notice of Exempt Offering of Securities on Form D with the United States Securities and Exchange Commission (the “SEC”) under Regulation D of the Securities Act of 1933, as amended (the “Securities Act”), (iv) those required by NYSE, including with respect to obtaining shareholder approval, (v) those required to consummate the Transaction as provided under the Transaction Agreement, (vi) the filing of notification under the Hart-Scott- Rodino Antitrust Improvements Act of 1976, if applicable, and (vii) the failure of which to obtain would not be reasonably likely to have a Company Material Adverse Effect.

f.    As of their respective dates (or, with respect to any amended filing, as of the date of the amendment), all reports required to be filed by the Company with the SEC (the “SEC Reports”) complied in all material respects with the requirements of the Securities Act and the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and the rules and regulations of the SEC promulgated thereunder, and none of the SEC Reports, when filed or amended, contained any untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading. The financial statements of the Company included in the SEC Reports comply in all material respects with applicable accounting requirements and the rules and regulations of the SEC with respect thereto as in effect at the time of filing and fairly present in all material respects the financial position of the Company as of and for the dates thereof and the results of operations and cash flows for the periods then ended, subject, in the case of unaudited statements, to normal, year-end audit adjustments.

All (i) issued and outstanding Common Stock has been duly authorized and validly issued, is fully paid and non-assessable and is not subject to preemptive rights and (ii) outstanding Warrants have been duly authorized and validly issued, are fully paid and are not subject to preemptive rights. As of the date hereof, except as set forth above and pursuant to (i) the Other Subscription Agreements, and (ii) the Transaction Agreement, there are no outstanding options, warrants or other rights to subscribe for, purchase or acquire from the Company any Common Stock or other equity interests in the Company (collectively, “Equity Interests”) or securities convertible into or exchangeable or exercisable for Equity Interests. The Company has no subsidiaries and does not own, directly or indirectly, interests or investments (whether equity or debt) in any person, whether incorporated or unincorporated.

k.    The Company has not received any written communication, from a governmental authority that alleges that the Company is not in compliance with or is in default or violation of any applicable antitrust or anticorruption law, except where such non- compliance, default or violation would not be reasonably expected to have a Company Material Adverse Effect.

l.    Except for Wells Fargo Securities, LLC, its affiliates or any of its or their control persons, officers, directors and employees, (the “Placement Agent”), no broker or finder is entitled to any brokerage or finder’s fee or commission solely in connection with the sale of the Subscribed Shares by the Company to Subscriber.

m.    The Company has not entered into any side letter or similar agreement with any Other Subscriber or any other investor in connection with such Other Subscriber’s or other investor’s direct or indirect investment in the Company other than (i) the Transaction Agreement and (ii) the Other Subscription Agreement.

b.    This Subscription Agreement has been duly executed and delivered by Subscriber, and assuming the due authorization, execution and delivery of the same by the Company, this Subscription Agreement shall constitute the valid and legally binding obligation of Subscriber, enforceable against Subscriber in accordance with its terms, except as such enforceability may be limited by bankruptcy, insolvency, reorganization, moratorium and similar laws affecting creditors generally and by the availability of equitable remedies.

c.    The execution and delivery of this Subscription Agreement, the purchase of the Subscribed Shares and the compliance by Subscriber with all of the provisions of this Subscription Agreement and the consummation of the transactions contemplated herein will not conflict with or result in a breach or violation of any of the terms or provisions of, or constitute a default under, or result in the creation or imposition of any lien, charge or encumbrance upon any of the property or assets of Subscriber pursuant to the terms of (i) any indenture, mortgage, deed of trust, loan agreement, lease, license or other agreement or instrument to which Subscriber is a party or by which Subscriber is bound or to which any of the property or assets of Subscriber is subject; (ii) the organizational documents of Subscriber; or (iii) any statute or any judgment, order, rule or regulation of any court or governmental agency or body, domestic or foreign, having jurisdiction over Subscriber or any of its properties that, in the case of clauses (i) and (iii), would reasonably be expected to have a Subscriber Material Adverse Effect.

d.    Subscriber (i) is an “institutional account” as defined in FINRA Rule 4512(c); (ii) is an institutional “accredited investor” (within the meaning of Rule 501(a) under the Securities Act) satisfying the applicable requirements set forth on Annex A, (iii) is acquiring the Subscribed Shares only for its own account and not for the account of others, or if Subscriber is subscribing for the Subscribed Shares as a fiduciary or agent for one or more investor accounts, each owner of such account is a “qualified institutional buyer” (within the meaning of Rule 501(a) under the Securities Act) and Subscriber has full investment discretion with respect to each such account, and the full power and authority to make the acknowledgements, representations and agreements herein on behalf of each owner of each such account, and (iv) is not acquiring the Subscribed Shares with a view to, or for offer or sale in connection with, any distribution thereof in violation of the Securities Act (and has provided the Company with the requested information on Annex A following the signature page hereto). Subscriber is not an entity formed for the specific purpose of acquiring the Subscribed Shares.

e.    Subscriber understands that the Subscribed Shares are being offered in a transaction not involving any public offering within the meaning of the Securities Act and that the Subscribed Shares have not been registered under the Securities Act or any state securities law in reliance on the availability of an exemption from such registration. Subscriber understands that the Subscribed Shares may not be resold, transferred, pledged or otherwise disposed of by Subscriber absent an effective registration statement under the Securities Act, except (i) to the Company or a subsidiary thereof, or (ii) pursuant to an applicable exemption from the registration requirements of the Securities Act, and, in each of cases (i) and (ii), in accordance with any applicable securities laws of the states and other jurisdictions of the United States.

f.    Subscriber understands and agrees that Subscriber is purchasing the Subscribed Shares directly from the Company. Subscriber acknowledges that there have not been any representations, warranties, covenants or agreements made to Subscriber by the Company, any other party to the Transaction or any other person or entity, including the Placement Agent, expressly or by implication, other than those representations, warranties, covenants and agreements of the Company expressly set forth in this Subscription Agreement, and the Subscriber expressly disclaims any representations, warranties, covenants or agreements not expressly set forth in this Subscription Agreement. In particular, without limiting the foregoing, Subscriber acknowledges that certain information provided by the Company was based on projections, forecasts, estimates, budgets or other prospective information, and such information is based on assumptions and estimates that are inherently uncertain and are subject to a wide variety of significant business, economic and competitive risks and uncertainties that could cause actual results to differ materially from those contained in the projections, and neither the Company nor any other person, including the Placement Agent, makes any representation relating to any such information.

g.    In making its decision to purchase the Subscribed Shares, Subscriber has relied solely upon independent investigation made by Subscriber. Subscriber acknowledges and agrees that Subscriber has received such information as Subscriber deems necessary to make an investment decision with respect to the Subscribed Shares, including with respect to the Company and the Transaction (including Sky Harbour and its subsidiaries (collectively, the “Acquired Companies”)). Subscriber represents and agrees that Subscriber and Subscriber’s professional advisor(s), if any, have had the full opportunity to ask such questions, receive such answers and obtain such information as Subscriber and such undersigned’s professional advisor(s), if any, have deemed necessary to make an investment decision with respect to the Subscribed Shares. Subscriber further acknowledges and agrees that the Placement Agent has not provided Subscriber with any information or advice with respect to the Subscribed Shares nor is such information or advice necessary or desired. The Placement Agent has not made nor makes any representation as to the Company or the Acquired Companies or the quality or value of the Subscribed Shares and the Placement Agent may have acquired non-public information with respect to the Company or the Acquired Companies which Subscriber agrees need not be provided to it. In connection with the issuance of the Subscribed Shares to Subscriber, the Placement Agent has not acted as a financial advisor or fiduciary to Subscriber. For the avoidance of the doubt, Subscriber acknowledges that it is not relying upon, and has not relied upon, any statement, representation or warranty made by the Placement Agent in making its investment or decision to invest in the Company.

h.    Subscriber became aware of this offering of the Subscribed Shares solely by means of direct contact between Subscriber and the Company or by means of contact from the Placement Agent and the Subscribed Shares were offered to Subscriber solely by direct contact between Subscriber and the Company or the Placement Agent. Subscriber did not become aware of this offering of the Subscribed Shares, nor were the Subscribed Shares offered to Subscriber, by any other means. Subscriber acknowledges that the Company represents and warrants that the Subscribed Shares (i) were not offered by any form of general solicitation or general advertising and (ii) are not being offered in a manner involving a public offering under, or in a distribution in violation of, the Securities Act, or any state securities laws.

i.    Subscriber acknowledges that it is aware that there are substantial risks incident to the purchase and ownership of the Subscribed Shares. Subscriber is a sophisticated institutional investor and has such knowledge and experience in financial and business matters, and in investing in private placement securities, as to be capable of evaluating the merits and risks of an investment in the Subscribed Shares. At the time of making its investment decision, Subscriber has had access to such financial and other information concerning the Company and its subsidiaries as Subscriber deemed necessary or desirable in making a decision to purchase the Subscribed Shares, including an opportunity to ask questions and receive answers from officers of the Company and to obtain additional information necessary to verify the accuracy of any information furnished to such Subscriber or to which such Subscriber had access. Such Subscriber has independently made its own analysis and decision to purchase the Subscribed Shares and determined based on its own independent review, and such professional advice from its own advisors (including as to tax, legal and accounting matters) as Subscriber may deem appropriate, that its purchase of the Subscribed Shares (i) is consistent with such Subscriber’s financial needs, objectives and condition, (ii) complies with all investment policies, guidelines and other restrictions that are applicable to such Subscriber, (iii) does not and will not violate any law, rule, regulation, agreement or other obligation to which such Subscriber is bound (assuming the accuracy of the Company’s representations and warranties contained herein), and (iv) is a fit, proper and suitable investment for Subscriber, notwithstanding the risks associated with a purchase of the Subscribed Shares.

j.    Subscriber has adequately analyzed and fully considered the risks of an investment in the Subscribed Shares and determined that the Subscribed Shares are a suitable investment for Subscriber and that Subscriber is able at this time and in the foreseeable future to bear the economic risk of a total loss of Subscriber’s investment in the Company. Subscriber acknowledges specifically that a possibility of total loss exists.

k.    Subscriber understands and agrees that no federal or state agency has passed upon or endorsed the merits of the offering of the Subscribed Shares or made any findings or determination as to the fairness of this investment.

l.    Subscriber is not (i) a person or entity named on the List of Specially Designated Nationals and Blocked Persons administered by the U.S. Treasury Department’s Office of Foreign Assets Control (“OFAC”) or in any Executive Order issued by the President of the United States and administered by OFAC (“OFAC List”), or a person or entity prohibited by any OFAC sanctions program, (ii) a Designated National as defined in the Cuban Assets Control Regulations, 31 C.F.R. Part 515, or (iii) a non-U.S. shell bank or providing banking services indirectly to a non-U.S. shell bank. Subscriber agrees to provide law enforcement agencies, if requested thereby, such records as required by applicable law, provided that Subscriber is permitted to do so under applicable law. Subscriber represents that if it is a financial institution subject to the Bank Secrecy Act (31 U.S.C. Section 5311 et seq.), as amended by the USA PATRIOT Act of 2001 and its implementing regulations (collectively, the “BSA/PATRIOT Act”), that Subscriber maintains policies and procedures reasonably designed to comply with applicable obligations under the BSA/PATRIOT Act. Subscriber also represents that, to the extent required, it maintains policies and procedures reasonably designed to ensure compliance with applicable OFAC sanctions programs, including the OFAC List. Subscriber further represents and warrants that, to the extent required, it maintains policies and procedures reasonably designed to ensure that the funds held by Subscriber and used to purchase the Subscribed Shares were legally derived.

m.    As of the date hereof Subscriber does not have, and during the thirty (30) day period immediately prior to the date hereof such Subscriber has not entered into, any “put equivalent position” as such term is defined in Rule 16a-1 under the Exchange Act or short sale positions with respect to the securities of the Company.

n.    If Subscriber is an employee benefit plan that is subject to Title I of ERISA, a plan, an individual retirement account or other arrangement that is subject to section 4975 of the Internal Revenue Code of 1986, as amended (the “Code”) or an employee benefit plan that is a governmental plan (as defined in section 3(32) of ERISA), a church plan (as defined in section 3(33) of ERISA), a non-U.S. plan (as described in section 4(b)(4) of ERISA) or other plan that is not subject to the foregoing but may be subject to provisions under any other federal, state, local, non-U.S. or other laws or regulations that are similar to such provisions of ERISA or the Code, or an entity whose underlying assets are considered to include “plan assets” of any such plan, account or arrangement (each, a “Plan”) subject to the fiduciary or prohibited transaction provisions of ERISA or section 4975 of the Code, Subscriber represents and warrants that neither the Company, nor any of its respective affiliates (the “Transaction Parties”) has acted as the Plan’s fiduciary, or has been relied on for advice, with respect to its decision to acquire and hold the Subscribed Shares, and none of the Transaction Parties shall at any time be relied upon as the Plan’s fiduciary with respect to any decision to acquire, continue to hold or transfer the Subscribed Shares.

o.    Subscriber is not currently (and at all times through the Closing will refrain from being or becoming) a member of a “group” (within the meaning of Section 13(d)(3) or Section 14(d)(2) of the Exchange Act, or any successor provision), including any group acting for the purpose of acquiring, holding or disposing of equity securities of the Company (within the meaning of Rule 13d-5(b)(1) under the Exchange Act).

Part 800.401, and no foreign person will have control (as defined in 31 C.F.R. Part 800.208) over the Company from and after the Closing as a result of the purchase and sale of Subscribed Shares hereunder.

q.    If Subscriber will purchase 20% of the Company’s securities, Subscriber represents that no disqualifying event described in Rule 506(d)(1)(i)-(viii) under the Securities Act (a “Disqualification Event”) is applicable to Subscriber or any of its Rule 506(d) Related Parties (as defined below), except, if applicable, for a Disqualification Event as to which Rule 506(d)(2)(ii) or (iii) or (d)(3) is applicable. Subscriber hereby agrees that it shall notify the Company promptly in writing in the event a Disqualification Event becomes applicable to Subscriber or any of its Rule 506(d) Related Parties, except, if applicable, for a Disqualification Event as to which Rule 506(d)(2)(ii) or (iii) or (d)(3) is applicable.

a.    The Company agrees that, by the later of (i) one-hundred-twenty (120) calendar days after the Closing Date or (ii) forty-five (45) calendar days after the expiration of the Lock-Up Period (as such term is defined in that certain Lock-Up Agreement, dated as of August 1, 2021, by and between the Company and the other parties thereto) (the “Filing Deadline”), the Company will file with the SEC (at the Company’s sole cost and expense) a registration statement (the “Registration Statement”) registering the resale of the Subscribed Shares, and the Company shall use its commercially reasonable efforts to have the Registration Statement declared effective as soon as practicable after the filing thereof, but no later than the 60th calendar day (or 90th calendar day if the SEC notifies the Company that it will “review” the Registration Statement) following the Filing Deadline (such date, the “Effectiveness Date”); provided, however, that the Company’s obligations to include the Subscribed Shares in the Registration Statement are contingent upon the undersigned furnishing in writing to the Company such information regarding the undersigned, the securities of the Company held by the undersigned and the intended method of disposition of the Subscribed Shares as shall be reasonably requested by the Company to effect the registration of the Subscribed Shares, and shall execute such documents in connection with such registration as the Company may reasonably request that are customary of a selling stockholder in similar situations. In no event shall the Subscriber be identified as a statutory underwriter in the Registration Statement unless in response to a comment or request from the staff of the SEC or another regulatory agency; provided, that if the SEC requests that the Subscriber be identified as a statutory underwriter in the Registration Statement, the Subscriber will have an opportunity to withdraw from the Registration Statement. The Company will use its commercially reasonable efforts to maintain the continuous effectiveness of the Registration Statement until the earliest of (i) the date on which the Subscribed Shares may be resold without volume or manner of sale limitations pursuant to Rule 144 promulgated under the Securities Act and without the requirement for the Company to be in compliance with the current public information required under Rule 144(c)(2) (or Rule 144(i)(2), if applicable), (ii) the date on which such Subscribed Shares have actually been sold and (iii) the date which is two (2) years after the Closing. For as long as the Registration Statement is required to be effective pursuant to this Section 6(a), the Company will use commercially reasonable efforts to (1) qualify the Subscribed Shares for listing on the NYSE or such other stock exchange upon which the Subscribed Shares are then eligible for listing, and (2) update or amend the Registration Statement as necessary to include the Subscribed Shares. For purposes of clarification, any failure by the Company to file the Registration Statement by the Filing Deadline or to effect such Registration Statement by the Effectiveness Date shall not otherwise relieve the Company of its obligations to file or effect the Registration Statement set forth in this Section 6.

b.    Notwithstanding anything to the contrary in this Subscription Agreement, the Company shall be entitled to delay or postpone the effectiveness of the Registration Statement, and from time to time to require any Subscriber not to sell under the Registration Statement or to suspend the effectiveness thereof, if the negotiation or consummation of a transaction by the Company or its subsidiaries is pending or an event has occurred, which negotiation, consummation or event, the Company reasonably believes, upon the advice of legal counsel, would require additional disclosure by the Company in the Registration Statement of material information that the Company has a bona fide business purpose for keeping confidential and the non-disclosure of which in the Registration Statement would be expected, in the reasonable determination of the Company, upon the advice of legal counsel, to cause the Registration Statement to fail to comply with applicable disclosure requirements (each such circumstance, a “Suspension Event”); provided, however, that the Company may not delay or suspend the Registration Statement on more than two (2) occasions or for more than sixty (60) consecutive calendar days, or more than one hundred and twenty (120) total calendar days, in each case during any twelve (12) month period. Upon receipt of any written notice from the Company of the happening of any Suspension Event (which notice shall not contain material non-public information) during the period that the Registration Statement is effective or if as a result of a Suspension Event the Registration Statement or related prospectus contains any untrue statement of a material fact or omits to state any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made (in the case of the prospectus) not misleading, each Subscriber agrees that (i) it will immediately discontinue offers and sales of the Subscribed Shares under the Registration Statement (excluding, for the avoidance of doubt, sales conducted pursuant to Rule 144) until such Subscriber receives copies of a supplemental or amended prospectus (which the Company agrees to promptly prepare) that corrects the misstatement(s) or omission(s) referred to above and receives notice that any post-effective amendment has become effective or unless otherwise notified by the Company that it may resume such offers and sales, and (ii) it will maintain the confidentiality of any information included in such written notice delivered by the Company unless otherwise required by law or subpoena. If so directed by the Company, each Subscriber will deliver to the Company or, in such Subscriber’s sole discretion destroy, all copies of the prospectus covering the Subscribed Shares in such Subscriber’s possession; provided, however, that this obligation to deliver or destroy all copies of the prospectus covering the Subscribed Shares shall not apply (i) to the extent such Subscriber is required to retain a copy of such prospectus (a) to comply with applicable legal, regulatory, self-regulatory or professional requirements or (b) in accordance with a bona fide pre-existing document retention policy or (ii) to copies stored electronically on archival servers as a result of automatic data back-up.

c.    The Company shall indemnify and hold harmless each Subscriber (to the extent a seller under the Registration Statement), its officers, directors and agents, and each person who controls such Subscriber (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) to the fullest extent permitted by applicable law, from and against any and all losses, claims, damages, liabilities, costs (including, without limitation, reasonable attorneys’ fees) and expenses (collectively, “Losses”), as incurred, that arise out of or are based upon any untrue or alleged untrue statement of a material fact contained in the Registration Statement (or incorporated by reference therein), any prospectus included in the Registration Statement or any form of prospectus or in any amendment or supplement thereto or in any preliminary prospectus, or arising out of or relating to any omission or alleged omission to state a material fact required to be stated therein or necessary to make the statements therein (in the case of any prospectus or form of prospectus or supplement thereto, in light of the circumstances under which they were made) not misleading, except to the extent, that such untrue statements or alleged untrue statements, omissions or alleged omissions are based upon information regarding Subscriber furnished in writing to the Company by Subscriber expressly for use therein or Subscriber has omitted a material fact from such information or otherwise violated the Securities Act, Exchange Act or any state securities law or any rule or regulation thereunder.

d.    The Subscriber shall indemnify and hold harmless the Company, its directors, officers, agents and employees, and each person who controls the Company (within the meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act), to the fullest extent permitted by applicable law, from and against all Losses, as incurred, arising out of or are based upon any untrue or alleged untrue statement of a material fact contained in any Registration Statement, any prospectus included in the Registration Statement, or any form of prospectus, or in any amendment or supplement thereto or in any preliminary prospectus, or arising out of or relating to any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein (in the case of any prospectus, or any form of prospectus or supplement thereto, in light of the circumstances under which they were made) not misleading to the extent, but only to the extent, that such untrue statements or omissions are based upon information regarding such Subscriber furnished in writing to the Company by such Subscriber expressly for use therein. In no event shall the liability of any Subscriber be greater in amount than the dollar amount of the net proceeds received by such Subscriber upon the sale of the Subscribed Shares giving rise to such indemnification obligation. Each Subscriber shall notify the Company promptly of the institution, threat or assertion of any proceeding arising from or in connection with the transactions contemplated by this Section 6 of which such Subscriber is aware.

7.    Termination. This Subscription Agreement shall terminate and be void and of no further force and effect, and all rights and obligations of the parties hereunder shall terminate without any further liability on the part of any party in respect thereof, upon the earliest to occur of (a) such date and time as the Transaction Agreement is terminated in accordance with its terms, (b) upon the mutual written agreement of the Company and the Subscriber to terminate this Subscription Agreement, (c) if, on the Closing Date, any of the conditions to Closing set forth in Section 2 of this Subscription Agreement have not been satisfied as of the time required hereunder to be so satisfied or waived by the party entitled to grant such waiver and, as a result thereof, the transactions contemplated by this Subscription Agreement are not consummated and (d) if the consummation of the Transaction shall not have occurred by the Outside Closing Date; provided, that nothing herein will relieve any party from liability for any willful breach hereof prior to the time of termination, and each party will be entitled to any remedies at law or in equity to recover losses, liabilities or damages arising from such breach. The Company shall notify Subscriber of the termination of the Transaction Agreement promptly after the termination thereof.

8.    Trust Account Waiver. Subscriber hereby acknowledges that the Company has established a trust account (the “Trust Account”) containing the proceeds of its initial public offering (the “IPO”) and from certain private placements occurring simultaneously with the IPO (including interest accrued from time to time thereon) for the benefit of the Company’s public shareholders and certain other parties (including the underwriters of the IPO). For and in consideration of the Company entering into this Subscription Agreement, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Subscriber hereby (i) agrees that it does not now and shall not at any time hereafter have any right, title, interest or claim of any kind in or to any assets held in the Trust Account, and shall not make any claim against the Trust Account, regardless of whether such claim arises as a result of, in connection with or relating in any way to this Subscription Agreement or any other matter, and regardless of whether such claim arises based on contract, tort, equity or any other theory of legal liability (any and all such claims are collectively referred to hereafter as the “Released Claims”), (ii) irrevocably waives any Released Claims that it may have against the Trust Account now or in the future as a result of, or arising out of, any negotiations, contracts or agreements with the Company, and (iii) will not seek recourse against the Trust Account for any reason whatsoever; provided however, that nothing in this Section 8 shall be deemed to limit any Subscriber’s right to distributions from the Trust Account in accordance with the Company’s amended and restated certificate of incorporation in respect of Common Stock of the Company acquired by any means other than pursuant to this Subscription Agreement.

9.    Miscellaneous.

a.    All notices, requests, demands, claims and other communications hereunder shall be in writing. Any notice, request, demand, claim or other communication hereunder shall be deemed duly given (i) when delivered personally to the recipient, (ii) when sent by electronic mail, on the date of transmission to such recipient; provided, that such notice, request, demand, claim or other communication is also sent to the recipient pursuant to clauses (i), (iii) or (iv) of this Section 9(a), (iii) one (1) Business Day after being sent to the recipient by reputable overnight courier service (charges prepaid), or (iv) four (4) Business Days after being mailed to the recipient by certified or registered mail, return receipt requested and postage prepaid, and, in each case, addressed to the intended recipient at its address specified on the signature page hereof or to such electronic mail address or address as subsequently modified by written notice given in accordance with this Section 9(a).

The Company acknowledges that Subscriber and others will rely on the acknowledgments, understandings, agreements, representations and warranties contained in this Subscription Agreement.

c.    Each of the Company and Subscriber is irrevocably authorized to produce this Subscription Agreement or a copy hereof to any interested party in any administrative or legal proceeding or official inquiry with respect to the matters covered hereby.

d.    Subscriber shall pay all of its own expenses in connection with this Subscription Agreement and the transactions contemplated herein.

e.    Neither this Subscription Agreement nor any rights that may accrue to Subscriber hereunder (other than the Subscribed Shares acquired hereunder, if any) may be transferred or assigned.

Notwithstanding the foregoing, Subscriber may assign its rights and obligations under this Subscription Agreement to one or more of its affiliates or another person acceptable to the Company, provided that no such assignment shall relieve Subscriber of its obligations hereunder if any such affiliate fails to perform such obligations.

f.    All the agreements, representations and warranties made by each party hereto in this Subscription Agreement shall survive the Closing.

g.    The Company may request from Subscriber such additional information as the Company may deem reasonably necessary to evaluate the eligibility of Subscriber to acquire the Subscribed Shares, and Subscriber shall provide such information as may be reasonably requested, to the extent readily available and to the extent consistent with its internal policies and procedures.

THE PARTIES AGREE THAT ANY SUCH CLAIM OR CAUSE OF ACTION SHALL BE TRIED BY A COURT TRIAL WITHOUT A JURY. WITHOUT LIMITING THE FOREGOING, THE PARTIES FURTHER AGREE THAT THEIR RESPECTIVE RIGHT TO A TRIAL BY JURY IS WAIVED BY OPERATION OF THIS SECTION AS TO ANY ACTION, COUNTERCLAIM OR OTHER PROCEEDING WHICH SEEKS, IN WHOLE OR IN PART, TO CHALLENGE THE VALIDITY OR ENFORCEABILITY OF THIS SUBSCRIPTION AGREEMENT OR ANY PROVISION HEREOF.

Each party hereby consents and submits to the exclusive jurisdiction of the Designated Courts. No legal action, suit or proceeding with respect to this Subscription Agreement may be brought in any other forum. Each party hereby irrevocably waives all claims of immunity from jurisdiction and any objection which such party may now or hereafter have to the laying of venue of any suit, action or proceeding in any Designated Court, including any right to object on the basis that any dispute, action, suit or proceeding brought in the Designated Courts has been brought in an improper or inconvenient forum or venue.

Nothing contained herein or in any Other Subscription Agreement, and no action taken by Subscriber or investor pursuant hereto or thereto, shall be deemed to constitute the Subscriber and other investors as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the Subscriber and other investors are in any way acting in concert or as a group with respect to such obligations or the transactions contemplated by this Subscription Agreement and the Other Subscription Agreements. Subscriber acknowledges that no Other Subscriber has acted as agent for the Subscriber in connection with making its investment hereunder and no Other Subscriber will be acting as agent of the Subscriber in connection with monitoring its investment in the Subscribed Shares or enforcing its rights under this Subscription Agreement. Subscriber shall be entitled to independently protect and enforce its rights, including without limitation the rights arising out of this Subscription Agreement, and it shall not be necessary for any Other Subscriber or investor to be joined as an additional party in any proceeding for such purpose.
