EXECUTION COPY

SUBSCRIPTION AGREEMENT

This SUBSCRIPTION AGREEMENT (this “Subscription Agreement”) is entered into on September 26, 2026, by and between Proem Acquisition Corp I., a Cayman Islands exempted company (“PAAC”), and the undersigned subscriber (“Subscriber”).

This Subscription Agreement substitutes and replaces any other previously signed Subscription Agreements (if any) between the Subscriber and PAAC.

WHEREAS, PAAC is entering into a Merger Agreement by and among PAAC, Astro Digital US, Inc., a Delaware corporation (“Astro Digital”), PAAC Merger Sub I, Inc., a Delaware corporation (“Merger Sub I”), and PAAC Merger Sub II, LLC, a Delaware limited liability company (“Merger Sub II”) (such merger agreement as amended, supplemented, restated or otherwise modified from time to time, the “Agreement” and the transactions contemplated by the Agreement, the “Transaction”);

WHEREAS, in connection with the Transaction and as more fully described in the Agreement, PAAC shall de-register from the Register of Companies in the Cayman Islands by way of continuation out of the Cayman Islands and into the State of Delaware so as to migrate to and domesticate as a Delaware corporation (the “Domestication”), and upon which, (i) Merger Sub I will merge with and into Astro Digital, with Astro Digital surviving the merger (the “Initial Surviving Corporation”, and such merger, the “First Company Merger”), and (ii) immediately following the First Company Merger, the Initial Surviving Corporation will merge with and into Merger Sub II (the “Second Company Merger” and together with the First Company Merger, the “Mergers”), with Merger Sub II continuing as the surviving entity and a wholly-owned subsidiary of PAAC, with PAAC remaining as the publicly listed combined company after its re-domestication as a Delaware company (referred to herein as “PubCo”);

WHEREAS, in connection with the Transaction, PAAC is seeking commitments from interested investors to purchase shares of the common stock of PubCo (the “Shares”) as set forth on the signature page hereto (the “Subscribed Securities”), in a private placement for a purchase price of $10.00 per share (the “Per Share Price” and the aggregate of such Per Share Price for all Subscribed Securities (as defined below) being referred to herein as the “Purchase Price”);

WHEREAS, Subscriber desires to subscribe for and purchase from PubCo, in connection with the consummation of the Transaction, the Subscribed Securities and PubCo desires to issue and sell, or cause to be issued and sold, to Subscriber the Subscribed Securities in consideration of the payment of the Purchase Price by or on behalf of Subscriber to PubCo; and

WHEREAS, concurrently with the execution of this Subscription Agreement, PubCo is entering into subscription agreements (the “Other Subscription Agreements” and together with the Subscription Agreement, the “Subscription Agreements”) with certain other investors (the “Other Subscribers” and together with Subscriber, the “Subscribers”), which are on substantially the same terms as the terms of this Subscription Agreement, pursuant to which such investors have agreed to purchase on the closing date of the Transaction (the “Closing Date”), inclusive of the Subscribed Securities, an aggregate amount of up to 5,000,000 Shares.

NOW, THEREFORE, in consideration of the foregoing and the mutual representations, warranties and covenants, and subject to the conditions, herein contained, and intending to be legally bound hereby, the parties hereto hereby agree as follows:

1. Subscription. Subject to the terms and conditions hereof, at the Closing (as defined below), Subscriber hereby subscribes for and agrees to purchase, and PubCo hereby agrees to issue and sell, or cause to be issued and sold, to Subscriber, upon the payment of the Purchase Price, the Subscribed Securities (such subscription and issuance, the “Subscription”).

2. Closing.

(a) The consummation of the Subscription contemplated hereby (the “Closing”) is only contingent upon the substantially concurrent consummation of the Transaction and shall occur on the Closing Date concurrently with the consummation of the Transaction.

(b) At least five Business Days (as defined below) before the anticipated Closing Date, PAAC shall deliver written notice to Subscriber (the “Closing Notice”) specifying: (i) the anticipated Closing Date and (ii) the wire instructions for delivery of the Purchase Price to PubCo or its designee. No later than two Business Days after receiving the Closing Notice, Subscriber shall (i) deliver to PubCo such information as is reasonably requested in the Closing Notice in order for PubCo to issue or cause to be issued the Subscribed Securities to Subscriber and (ii) deliver the Purchase Price by wire transfer of United States dollars in immediately available funds to the account specified in the Closing Notice, such funds to be held in escrow by a third-party escrow provider selected by PAAC until the Closing or as otherwise provided herein in accordance with Section 2(d). Upon satisfaction (or, if applicable, waiver) of the conditions set forth in this Section 2, at the Closing the Purchase Price shall be released from escrow automatically and without further action by PAAC, PubCo or Subscriber.

(c) On the Closing Date, PubCo shall deliver, or cause to be delivered, to Subscriber: (i) the Subscribed Securities, against payment of the Purchase Price to be released from the escrow, and cause the Subscribed Securities to be registered in book entry form, free and clear of any liens or other restrictions (other than those arising under this Subscription Agreement or state or federal securities laws), in the name of Subscriber (or its nominee in accordance with its delivery instructions) or to a custodian designated by Subscriber, as applicable, on PubCo’s share register and provide to Subscriber evidence of such issuance from the transfer agent (the “Transfer Agent”), and (ii) a written record from PubCo or its Transfer Agent evidencing the issuance to Subscriber of the Subscribed Securities on and as of the Closing Date.

(d) In the event that the consummation of the Transaction does not occur within five Business Days after the anticipated Closing Date specified in the Closing Notice (unless otherwise agreed to in writing by PAAC and Subscriber), such third-party escrow provider, as applicable, shall promptly (but in no event later than seven Business Days thereafter) cause the return of the funds so delivered by Subscriber by wire transfer in immediately available funds to the account specified by Subscriber, and any book entries shall be deemed cancelled; provided, however, that unless this Subscription Agreement has been terminated pursuant to Section 7 below, such return of funds shall not terminate this Subscription Agreement or relieve Subscriber of its obligation to redeliver funds to PubCo on the new Closing Date following PubCo redelivering to Subscriber a new Closing Notice and to purchase the Subscribed Securities at the Closing. For the purposes of this Subscription Agreement, “Business Day” means any day other than a Saturday, Sunday or a day on which either the Federal Reserve Bank of New York or governmental authorities in the Cayman Islands (for so long as PAAC remains domiciled in Cayman Islands) are authorized or required by law to close.

(e) The Closing shall be subject to the satisfaction or valid waiver by PAAC, on the one hand, or Subscriber, on the other, of the conditions that, on the Closing Date:

(i) no suspension of the qualification of the Subscribed Securities for offering or sale or trading in any jurisdiction, or initiation or threatening of any proceedings for any of such purposes, shall have occurred;

(ii) all conditions precedent to the closing of the Transaction set forth in Article 9 of the Agreement (other than those conditions which, by their nature, are to be satisfied at the Closing) shall have been satisfied or waived, and the closing of the Transaction shall be scheduled to occur substantially concurrently with or immediately following the Closing;

(iii) no governmental authority shall have enacted, issued, promulgated, enforced or entered any judgment, order, law, rule or regulation (whether temporary, preliminary or permanent) which is then in effect and has the effect of making consummation of the transactions contemplated hereby illegal or otherwise restraining or prohibiting consummation of the transactions contemplated hereby; and

(iv) the Subscribed Securities shall be qualified for listing on The Nasdaq Stock Market (the “Nasdaq”) or an approved stock exchange as permitted under the Agreement (an “Approved Exchange”).

(f) The obligation of PAAC to consummate the Closing shall be subject to the satisfaction or valid waiver by PAAC of the additional conditions that, on the Closing Date:

(i) all representations and warranties of Subscriber contained in this Subscription Agreement shall be true and correct in all material respects (other than representations and warranties that are qualified as to materiality or Subscriber Material Adverse Effect (as defined below), which representations and warranties shall be true in all respects) at and as of the Closing Date; and

(ii) Subscriber shall have performed, satisfied and complied in all material respects with all covenants, agreements and conditions required by this Subscription Agreement to be performed, satisfied or complied with by it at or prior to the Closing.

(g) The obligation of Subscriber to consummate the Closing shall be subject to the satisfaction or valid waiver by Subscriber of the additional conditions that, on the Closing Date:

(i) all representations and warranties of PAAC contained in this Subscription Agreement shall be true and correct in all material respects (other than (x) representations and warranties that are qualified as to materiality or Company Material Adverse Effect (as defined below) and (y) the representations and warranties of PAAC in Section 3(o), which representations and warranties shall be true in all respects) at and as of the Closing Date;

(ii) PAAC shall have performed, satisfied and complied in all material respects with all covenants, agreements and conditions required by this Subscription Agreement to be performed, satisfied or complied with by it at or prior to the Closing; and

(iii) except to the extent consented in writing by the Subscriber, no amendment, modification or waiver of the Agreement shall have occurred that materially and adversely affects the number of Subscribed Securities, Per Share Price or the Purchase Price of the Subscribed Securities that Subscriber is acquiring pursuant to this Subscription Agreement.

(h) No later than two business days prior to the Closing, Subscriber shall deliver to PAAC a duly completed and executed Internal Revenue Service Form W-9 or appropriate Form W-8.

(i) At and from the Closing, PubCo and Subscriber shall execute and deliver such additional documents and take such additional actions as the parties reasonably may deem to be practical and necessary in order to consummate the Subscription as contemplated in this Subscription Agreement.

3. PAAC Representations and Warranties. PAAC represents and warrants to Subscriber that:

(a) PAAC (i) is an exempted company duly incorporated, validly existing and in good standing under the laws of the Cayman Islands (to the extent such concept exists in such jurisdiction) and, as of the Closing Date, following the Domestication and Mergers, PubCo will be duly incorporated, validly existing as a corporation and in good standing under the laws of the State of Delaware, (ii) has the requisite power and authority to own, lease and operate its properties, to carry on its business as it is now being conducted and to enter into and perform its obligations under this Subscription Agreement, and (iii) is duly licensed or qualified to conduct its business and, if applicable, is in good standing under the laws of each jurisdiction (other than its jurisdiction of incorporation) in which the conduct of its business or the ownership of its properties or assets requires such license or qualification, except, with respect to the foregoing clause (iii), where the failure to be in good standing would not reasonably be expected to have a Company Material Adverse Effect or have a material adverse effect on PubCo’s ability to consummate the transactions contemplated hereby, including the issuance and sale of the Subscribed Securities. For purposes of this Subscription Agreement, a “Company Material Adverse Effect” means an event, change, development, occurrence, condition or effect with respect to PAAC, PubCo 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 the business, financial condition, stockholders equity or results of operations of PAAC, PubCo and its subsidiaries, taken together as a whole (on a consolidated basis).

(b) As of the Closing Date, the Subscribed Securities will be 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 or subject to any preemptive or similar rights created under PubCo’s organizational documents (as in effect at such time of issuance) or the laws of its jurisdiction of incorporation. As of the date hereof, except pursuant to, or as contemplated by, (i) the Other Subscription Agreements, (ii) the redeemable warrants, each whole warrant entitles the holder thereof to purchase one ordinary share at a price of $11.50 per share, subject to adjustment (the “warrants”), (iii) the private placement units, comprised of one ordinary share and one-half of one warrant, or (iv) as disclosed in the Agreement (including the exhibits and schedules thereto), there are no outstanding options, warrants or other rights to subscribe for, purchase or acquire from PubCo any shares of common stock or other equity interests in PubCo (collectively, “Equity Interests”) or securities convertible into or exchangeable or exercisable for Equity Interests. As of the date hereof, with the exception of the aforementioned wholly owned merger subsidiaries, PubCo has no subsidiaries and does not own, directly or indirectly, interests or investments (whether equity or debt) in any person, whether incorporated or unincorporated. There are no shareholder agreements, voting trusts or other agreements or understandings to which PubCo is a party or by which it is bound relating to the voting of any Equity Interests, other than as contemplated by the Agreement. Except as disclosed in the Agreement (including the exhibits and schedules thereto), there are no securities or instruments issued by PAAC or to which PAAC is a party containing anti-dilution or similar provisions that will be triggered, by (i) the issuance of the Subscribed Securities or the shares to be issued pursuant to any Other Subscription Agreement, (ii) the Mergers or (iii) the Transaction, except in each case for such anti-dilution or similar provisions the application of which has been effectively waived.

(c) This Subscription Agreement has been duly authorized, executed and delivered by PAAC, 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 PAAC and, following the Transactions, PubCo, enforceable against PAAC and PubCo in accordance with its terms, except as such enforceability may be limited or otherwise affected by bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and similar laws relating to or affecting the rights of 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 Securities and the compliance by PAAC 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 PAAC pursuant to the terms of (i) any indenture, mortgage, deed of trust, loan agreement, lease, license or other agreement or instrument to which PAAC is a party or by which PAAC is bound or to which any of the property or assets of PAAC is subject; (ii) the organizational documents of PAAC; 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 PAAC 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 or have a material adverse effect on PAAC’s ability to consummate the transactions contemplated hereby, including the issuance and sale of the Subscribed Securities.

(e) PAAC is not in default or violation (and no event has occurred which, with notice or the lapse of time or both, would constitute a default or violation) of any term, condition or provision of (i) the organizational documents of PAAC, (ii) any loan or credit agreement, guarantee, note, bond, mortgage, indenture, lease or other agreement, permit, franchise or license to which, as of the date of this Subscription Agreement, PAAC is a party or by which PAAC’s properties or assets are bound or (iii) any statute or any judgment, order, rule or regulation of any court or governmental agency, taxing authority or regulatory body, domestic or foreign, having jurisdiction over PAAC or PubCo or any of its properties, except, in the case of clauses (ii) and (iii), for defaults or violations that have not had and would not be reasonably likely to have, individually or in the aggregate, a Company Material Adverse Effect.

(f) [Intentionally Omitted.].

(g) Assuming the accuracy of the representations and warranties of Subscriber set forth in Section 4 of this Subscription Agreement, PAAC 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 Nasdaq) or other person in connection with the execution, delivery and performance of this Subscription Agreement (including, without limitation, the issuance of the Subscribed Securities), other than (i) filings required by applicable state securities laws, (ii) the filing of the Registration Statement pursuant to Section 5 below, (iii) the filing of a Notice of Exempt Offering of Securities on Form D with the United States Securities and Exchange Commission (“Commission”) under Regulation D under the Securities Act of 1933, as amended (the “Securities Act”), if applicable, (iv) those required by Nasdaq, including with respect to obtaining stockholder approval of the Transaction, (v) those required to consummate the Transaction as provided under the 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 or have a material adverse effect on PubCo’s ability to consummate the transactions contemplated hereby, including the issuance and sale of the Subscribed Securities.

(h) As of their respective dates, all reports (the “SEC Reports”) required to be filed by PAAC with the Commission since its initial registration statement of the units and until the date hereof under Sections 13 or 15(d) of the Securities Exchange Act of 1934, as amended, and the rules and regulations of the Commission promulgated thereunder (the “Exchange Act”), complied in all material respects with the requirements of the Exchange Act and none of the SEC Reports, when filed, contained any untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. The financial statements of PAAC included in the SEC Reports comply in all material respects with applicable accounting requirements and the rules and regulations of the Commission with respect thereto as in effect at the time of filing and fairly present in all material respects the financial position of PAAC 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. There are no material outstanding or unresolved comments in comment letters from the Commission staff with respect to any of the SEC Reports.

(i) As of the date hereof, the issued and outstanding ordinary shares of PAAC are registered pursuant to Section 12(b) of the Exchange Act, and are listed for trading on Nasdaq under the symbol “PAAC”. There is no suit, action, proceeding or investigation pending or, to the knowledge of PAAC, threatened against PAAC by Nasdaq or the Commission with respect to any intention by such entity to deregister the its ordinary shares or prohibit or terminate the listing of the its ordinary shares on Nasdaq. PAAC has taken no action that is designed to terminate the registration of its ordinary shares under the Exchange Act or the listing of the ordinary shares on Nasdaq. Following the Mergers, PubCo’s shares of common stock are expected to be registered under the Exchange Act and listed for trading on an Approved Exchange.

(j) PAAC is in compliance with all applicable laws, except where such non-compliance would not be reasonably likely to have a Company Material Adverse Effect.

(k) Except for such matters as have not had and would not be reasonably likely to have a Company Material Adverse Effect or have a material adverse effect on PAAC’s ability to consummate the transactions contemplated hereby, including the issuance and sale of the Subscribed Securities, as of the date hereof, there is no (i) suit, action, proceeding or arbitration before a governmental authority or arbitrator pending, or, to the knowledge of PAAC, threatened in writing against PAAC or (ii) judgment, decree, injunction, ruling or order of any governmental authority or arbitrator outstanding against PAAC.

(l) Assuming the accuracy of Subscriber’s representations and warranties set forth in Section 4 below, no registration under the Securities Act is required for the offer and sale of the Subscribed Securities by PubCo to Subscriber.

(m) Neither PAAC nor any person acting on its behalf has engaged or will engage in any form of general solicitation or general advertising (within the meaning of Regulation D) in connection with any offer or sale of the Subscribed Securities.

(n) PAAC is not under any obligation to pay any broker’s fee or commission in connection with the sale of the Subscribed Securities.

(o) Other than the Other Subscription Agreements, PAAC has not entered into any side letter or similar agreement with any Other Subscribers in connection with Other Subscription Agreements, other than such Other Subscription Agreements that include (i) any rights or benefits granted to an Other Subscriber in connection with such Other Subscriber’s compliance with any law, regulation or policy specifically applicable to such Other Subscriber or in connection with the taxable status of an Other Subscriber, (ii) any rights or benefits which are personal to an Other Subscriber based solely on its place of organization or headquarters, organizational form of, or other particular restrictions applicable to, such Other Subscriber or (iii) other terms with respect to the purchase of the Subscribed Securities that are no more favorable in any material respect to such Other Subscriber thereunder than the terms of this Subscription Agreement.

(p) PAAC is not, and immediately after receipt of payment for the Subscribed Securities will not be, an “investment company” within the meaning of the Investment Company Act of 1940, as amended.

4. Subscriber Representations and Warranties. Subscriber represents and warrants to PAAC that:

(a) Subscriber (i) is duly organized, validly existing and in good standing under the laws of its jurisdiction of formation or incorporation, and (ii) has the requisite power and authority to enter into and perform its obligations under this Subscription Agreement.

(b) This Subscription Agreement has been duly authorized, executed and delivered by Subscriber, and assuming the due authorization, execution and delivery of the same by PAAC, 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 Securities 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 (x) a “qualified institutional buyer” (as defined in Rule 144A under the Securities Act) or (y) an “accredited investor” (within the meaning of Rule 501(a) under the Securities Act) satisfying the applicable requirements set forth on Annex A hereto; (ii) is acquiring the Subscribed Securities only for its own account and not for the account of others, or if Subscriber is subscribing for the Subscribed Securities as a fiduciary or agent for one or more investor accounts, each owner of such account is a qualified institutional buyer 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 (iii) is not acquiring the Subscribed Securities with a view to, or for offer or sale in connection with, any distribution thereof in violation of the Securities Act or the securities laws of any other jurisdiction (and has provided PAAC with the requested information on Annex A following the signature page hereto).

Subscriber has determined based on its own independent review and such professional advice as it deems appropriate that its purchase of the Subscribed Securities and participation in the Subscription (i) are fully consistent with its financial needs, objectives and condition, (ii) comply and are fully consistent with all investment policies, guidelines and other restrictions applicable to it, (iii) have been duly authorized and approved by all necessary action, and (iv) do not and will not violate or constitute a default under its charter, by-laws or other constituent document or under any law, rule, regulation, agreement or other obligation by which it is bound.

(e) Subscriber understands that the Subscribed Securities are being offered in a transaction not involving any public offering within the meaning of the Securities Act and that the Subscribed Securities have not been registered under the Securities Act. Subscriber understands that the Subscribed Securities may not be resold, transferred, pledged or otherwise disposed of by Subscriber absent an effective registration statement under the Securities Act, except (i) to PAAC 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, and that any book entry positions representing the Shares shall contain a restrictive legend (the “Restricted Legend”) to such effect.

Subscriber acknowledges and agrees that the Subscribed Securities will not immediately be eligible for offer, resale, transfer, pledge or disposition pursuant to Rule 144 promulgated under the Securities Act, and that the provisions of Rule 144(i) will apply to the Subscribed Securities. Subscriber understands that it has been advised to consult legal counsel prior to making any offer, resale, transfer, pledge or other disposition of any of the Subscribed Securities.

(f) In making its decision to purchase the Subscribed Securities, Subscriber has relied solely upon independent investigation made by Subscriber. Subscriber acknowledges and agrees that Subscriber has received such information as Subscriber deems necessary in order to make an investment decision with respect to the Subscribed Securities, including with respect to PAAC, PubCo (including Astro Digital) and the Transaction. Subscriber represents and agrees that Subscriber and Subscriber’s professional advisor(s), if any, have (i) 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 Securities and (ii) conducted and completed independent due diligence with respect to the Subscription and the Subscribed Securities. Based on such information as Subscriber has deemed appropriate and without reliance upon PAAC or any of its officers, directors, employees or other representatives, legal counsel, financial advisors, accountants or agents (collectively, “Representatives”), Subscriber has independently made its own analysis and decision to enter into the Subscription, and has not relied on any statements or other information provided by any of PAAC, PubCo, Astro Digital and its affiliates or their respective Representatives (collectively, the “Covered Persons”), with respect to PAAC, PubCo, Astro Digital or the Subscribed Securities, except for the representations, warranties and agreements of PAAC and PubCo set forth herein. In addition, except for the representations, warranties and agreements of PAAC and PubCo set forth herein, Subscriber is relying exclusively on its own sources of information, investment analysis and due diligence (including professional advice it deems appropriate) with respect to the Subscription, the Subscribed Securities and the business, condition (financial and otherwise), management, operations, properties and prospects of PAAC, PubCo and Astro Digital and its affiliates, including but not limited to all business, legal, regulatory, accounting, credit and tax matters.

(g) Subscriber hereby acknowledges and agrees that no disclosure or offering document has been prepared in connection with the offer and sale of the Subscribed Securities by any Covered Person, and no Covered Person has made or will make any representation or warranty (except for the representations and warranties of PAAC and PubCo set forth herein), whether express or implied, of any kind or character and has not provided any advice or recommendation in connection with the Subscription.

(h) Subscriber became aware of this offering of the Subscribed Securities solely by means of direct contact between Subscriber and PAAC and the Subscribed Securities were offered to Subscriber solely by direct contact between Subscriber and PAAC. Subscriber did not become aware of this offering of the Subscribed Securities, nor were the Subscribed Securities offered to Subscriber, by any other means. Subscriber acknowledges that PAAC represents and warrants that the Subscribed Securities (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. Subscriber acknowledges that Subscriber shall be responsible for any of Subscriber’s tax liabilities that may arise as a result of the transactions contemplated by this Subscription Agreement, and that neither PAAC, PubCo nor Astro Digital and its affiliates has provided any tax advice or any other representation or guarantee regarding the tax consequences of the transactions contemplated by the Subscription Agreement.

(i) Subscriber acknowledges that it is aware that there are substantial risks incident to the purchase and ownership of the Subscribed Securities. Subscriber has such knowledge and experience in financial and business matters as to be capable of evaluating the merits and risks of an investment in the Subscribed Securities, and Subscriber has had an opportunity to seek, and has sought, such accounting, legal, business and tax advice as Subscriber has considered necessary to make an informed investment decision.

(j) Subscriber has adequately analyzed and fully considered the risks of an investment in the Subscribed Securities and determined that the Subscribed Securities 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 PAAC. Subscriber acknowledges specifically that a possibility of total loss exists. Subscriber has exercised independent judgment in evaluating its participation in the Subscription.

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

(l) Neither Subscriber nor any of its officers, directors, managers, managing members, general partners or any other person acting in a similar capacity or carrying out a similar function is: (i) a person or entity named on the List of Specially Designated Nationals and Blocked Persons, the Foreign Sanctions Evaders List, the Sectoral Sanctions Identification List or any other similar list of sanctioned 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 or in any similar list of sanctioned persons administered by the European Union or any individual European Union member state or by the United Kingdom (collectively, the “Sanctions Lists”) or a person or entity prohibited by any OFAC sanctions program; (ii) directly or indirectly owned or controlled by, or acting on behalf of, one or more persons on a Sanctions List; (iii) organized, incorporated, established, located, resident or born in, or a citizen, national or the government, including any political subdivision agency, or instrumentality thereof, of, Cuba, Iran, North Korea, Syria, Venezuela, the Crimea region of Ukraine or any other country or territory embargoed or subject to substantial trade restrictions by the United States, the European Union or any individual European Union member state or the United Kingdom; (iv) a Designated National as defined in the Cuban Assets Control Regulations, 31 C.F.R. Part 515; or (v) a non-U.S. shell bank or providing banking services indirectly to a non-U.S. shell bank (collectively, a “Prohibited Investor”). 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, either directly or through the use of a third-party administrator, policies and procedures reasonably designed to comply with applicable obligations under the BSA/PATRIOT Act. Subscriber also represents that, to the extent applicable, it maintains policies and procedures reasonably designed to ensure compliance with sanctions administered by the United States, the European Union or any individual European Union member state or the United Kingdom. Subscriber further represents and warrants that, to the extent applicable, it maintains, either directly or through the use of a third-party administrator, policies and procedures reasonably designed to ensure that the funds held by Subscriber and used to purchase the Subscribed Securities were legally derived and were not obtained, directly or indirectly, from a Prohibited Investor, and that such funds held by Subscriber and used to purchase the Subscribed Securities were legally derived and were not obtained, directly or indirectly, from a Prohibited Investor.

(m) (i) Subscriber is not a ‘foreign person’ as defined in 31 C.F.R. § 800.224, and is not directly or indirectly controlled by a ‘foreign person,’ or (ii) if Subscriber is a ‘foreign person’ or is controlled by a ‘foreign person,’ Subscriber’s acquisition of the Subscribed Securities does not constitute a ‘covered transaction’ under the DPA (as defined below) that would trigger a mandatory declaration or notice filing requirement with the Committee on Foreign Investment in the United States (“CFIUS”). As used in this Section 4(m), “DPA” means the Defense Production Act of 1950, as amended (including by the Foreign Investment Risk Review Modernization Act of 2018), 50 U.S.C. § 4565, and all rules and regulations promulgated thereunder, including 31 C.F.R. Parts 800 and 802. No foreign government or foreign government-controlled entity (as such terms are understood under 31 C.F.R. Part 800) holds, directly or indirectly, a 25% or greater voting interest in Subscriber, or otherwise exercises control (as defined in 31 C.F.R. § 800.208) over Subscriber, and Subscriber has not entered into any agreement, arrangement, or understanding with any foreign government or foreign government-controlled entity that would grant such person any DPA Triggering Rights (as defined in the Agreement) with respect to PAAC, PubCo, Astro Digital, or any member of the Company Group. As of the date hereof, there are no pending or, to Subscriber’s knowledge, threatened reviews, investigations, notices, declarations, or proceedings by or before CFIUS relating to Subscriber’s investment in PubCo, Astro Digital, or any member of the Company Group, and no prior investment by Subscriber in Astro Digital has been the subject of any CFIUS review, investigation, declaration, or notice.

(n) Subscriber does not have, as of the date hereof, any “put equivalent position” as such term is defined in Rule 16a-1 under the Exchange Act, any “short sales” as defined in Rule 200 promulgated under Regulation SHO under the Exchange Act, and any type of direct or indirect stock pledges (other than pledges in the ordinary course of business as part of prime brokerage arrangements), forward sale contracts, options, puts, calls, swaps and similar arrangements (including on a total return basis), and or other short sale positions, whether through a broker dealer or otherwise, with respect to the securities of PAAC (collectively, “Short Sales”). Subscriber will not, during the period commencing on the date hereof and until the closing of the Transaction, engage in any Short Sales with respect to the Subscribed Securities. Notwithstanding the foregoing, in the case (i) other entities under common management with Subscriber that have no knowledge of this Subscription Agreement or of Subscriber’s participation in the Transaction (including Subscriber’s affiliates) or (ii) Subscriber is a multi-managed investment vehicle whereby separate portfolio managers manage separate portions of such Subscriber’s assets and the portfolio managers have no direct knowledge of the investment decisions made by the portfolio managers managing other portions of such Subscriber’s assets, then, in each case, the foregoing representation shall only apply with respect to the portion of assets managed by the portfolio manager that made the investment decision to purchase the Subscribed Securities covered by this Agreement.

(o) 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 PubCo, 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 Securities, 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 Securities.

(p) At the Closing, Subscriber will have sufficient funds to pay the Purchase Price pursuant to Section 2(b) above and consummate the purchase and sale of the Subscribed Securities when required pursuant to this Subscription Agreement.

(q) Subscriber acknowledges its obligations under applicable securities laws with respect to the treatment of non-public information relating to PAAC, PubCo and Astro Digital and its affiliates.

(r) Subscriber agrees that, notwithstanding Section 9(j) below, after the Closing, PubCo may rely upon the representations and warranties made by Subscriber to PAAC and PubCo in this Subscription Agreement.

(s) At all times prior to the Closing Date, Subscriber has no binding commitment to dispose of, or otherwise transfer (directly or indirectly) any of the Subscribed Securities.

5. Registration of Subscribed Securities.

(a) PAAC agrees that, within 30 calendar days following the Closing Date (the “Filing Date”), PubCo will file with the Commission (at PubCo’s sole cost and expense) a registration statement registering the resale of the Subscribed Securities (the “Registration Statement”), Registration Statement and PubCo shall use its commercially reasonable efforts to have the Registration Statement declared effective as soon as practicable thereafter, but in any event no later than the earlier of (i) 60 calendar days after the Filing Date thereof (or, in the event the Commission notifies PubCo that it will “review” the Registration Statement, the 90th calendar day following the Filing Date thereof) and (ii) 15 Business Days after the date PubCo is notified in writing by the Commission that the Registration Statement will not be “reviewed” or will not be subject to further review (such earlier date, the “Effectiveness Date”); provided, that if such date falls on a Saturday, Sunday or other day that the Commission is closed for business, the Effectiveness Date shall be extended to the next business day on which the Commission is open for business. PubCo will provide a draft of the Registration Statement to Subscriber for review (but not comment) at least two Business Days in advance of the filing of the Registration Statement. Notwithstanding the foregoing, if the Commission prevents PubCo from including any or all of the shares proposed to be registered under the Registration Statement due to limitations on the use of Rule 415 under the Securities Act for the resale of the Subscribed Securities by the applicable stockholders or otherwise, such Registration Statement shall register for resale such number of Subscribed Securities which is equal to the maximum number of Subscribed Securities as is permitted to be registered by the Commission. In such event, the number of Subscribed Securities to be registered for each selling stockholder named in the Registration Statement shall be reduced pro rata among all such selling stockholders and as promptly as practicable after being permitted to register additional Subscribed Securities under Rule 415 under the Securities Act, PubCo shall use commercially reasonable efforts to amend the Registration Statement or file a new Registration Statement to register such additional Subscribed Securities and cause such amendment or Registration Statement to become effective as promptly as practicable. For purposes of clarification, any failure by PubCo to file the Registration Statement by the Filing Date or to effect such Registration Statement by the Effectiveness Date shall not otherwise relieve PubCo of its obligations to file or effect the Registration Statement as set forth above in this Section 5(a).

(b) PAAC agrees that, except for such times as PubCo is permitted hereunder to suspend the effectiveness or use of the prospectus forming part of a Registration Statement, PubCo will use best efforts to cause such Registration Statement, or another shelf registration statement that includes the Subscribed Securities, to remain effective with respect to Subscriber until the earlier of (i) the date on which all of the Subscribed Securities shall have been sold, and (ii) the first date on which Subscriber can sell all of its Subscribed Securities (or shares received in exchange therefor) under Rule 144 under the Securities Act without limitation as to the manner of sale or the amount of such securities that may be sold and without the requirement for PubCo to be in compliance with the current public information required under Rule 144(c)(1) (or Rule 144(i)(2), if applicable). For as long as the Registration Statement shall remain effective pursuant to the immediately preceding sentence, PubCo will use commercially reasonable efforts to file all reports, and provide all customary and reasonable cooperation, necessary to enable Subscriber to resell the Subscribed Securities pursuant to the Registration Statement, qualify the Subscribed Securities for listing on the applicable stock exchange on which PubCo’s shares of common stock are then listed, and update or amend the Registration Statement as necessary to include the Subscribed Securities.

(c) Subscriber agrees to disclose its beneficial ownership, as determined in accordance with Rule 13d-3 under the Exchange Act, of Subscribed Securities to PubCo (or its successor) upon request to assist PubCo in making the determination described above. PAAC’s and PubCo’s obligations to include the Subscribed Securities in the Registration Statement are contingent upon Subscriber furnishing in writing to PubCo such information regarding Subscriber, the securities of PubCo held by Subscriber and the intended method of disposition of the Subscribed Securities as shall be reasonably requested by PubCo to effect the registration of the Subscribed Securities, and Subscriber shall execute such documents in connection with such registration as PubCo may reasonably request that are customary for a selling stockholder in similar situations; provided that Subscriber shall not in connection with the foregoing be required to execute any lock-up or similar agreement or otherwise be subject to any contractual restriction on the ability to transfer the Subscribed Securities.

(d) Subscriber agrees PubCo shall be entitled to postpone and suspend the effectiveness or use of the Registration Statement during any customary blackout or similar period or as permitted hereunder. In the case of the registration effected by PubCo pursuant to this Subscription Agreement, PubCo shall, upon reasonable request, inform Subscriber as to the status of such registration. In no event shall Subscriber be identified as a statutory underwriter in the Registration Statement unless requested by the Commission. If the Commission requests that Subscriber be identified as a statutory underwriter in the Registration Statement, Subscriber will have an opportunity to withdraw from the Registration Statement. Subscriber shall not be entitled to use the Registration Statement for an underwritten offering of Subscribed Securities. Notwithstanding anything to the contrary contained herein, PubCo may delay or postpone filing of such Registration Statement, and from time to time require Subscriber not to sell under the Registration Statement or suspend the use or effectiveness of any such Registration Statement, if it determines that in order for the registration statement to not contain a material misstatement or omission, an amendment thereto would be needed to include information that would at that time not otherwise be required in a current, quarterly, or annual report under the Exchange Act, or PubCo’s Chief Executive Officer or CFO believes such filing or use could materially affect a bona fide business or financing transaction of PubCo or would require premature disclosure of information that could materially adversely affect PubCo (each such circumstance, a “Suspension Event”); provided that PubCo shall not declare more than two Suspension Events in any 12-month period; provided further, that no Suspension Event shall be declared within the 30 days following the conclusion of a prior delay in the filing of or initial effectiveness of, or suspension of use of, the Registration Statement (“Suspension Period”); provided further, that the total Suspension Period in any consecutive 12-month period shall not exceed an aggregate of 120 days. Notwithstanding the foregoing, if for any reason the Registration Statement has not been declared effective by the Commission by the 90th calendar day following the Filing Date, then from and after the 91st calendar day following the Filing Date until such time as the Registration Statement is declared effective, PubCo shall pay to Subscriber interest on the Purchase Price at a rate of 12% per annum, accruing daily and payable in cash on a quarterly basis in arrears, as sole and exclusive liquidated damages for such failure and not a penalty. Such interest shall cease to accrue on the date the Registration Statement is declared effective by the Commission.

(e) At its expense, PubCo shall advise Subscriber within two Business Days: (i) of the issuance by the Commission of any stop order suspending the effectiveness of any Registration Statement or the initiation of any proceedings for such purpose; (ii) of the receipt by PubCo of any notification with respect to the suspension of the qualification of the Subscribed Securities included therein for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose; and (iii) subject to the provisions in this Subscription Agreement, of the occurrence of a Suspension Event or any other event that requires the making of any changes in any Registration Statement or prospectus so that, as of such date, the statements therein are not misleading and do not omit to state a material fact required to be stated therein or necessary to make the statements therein (in the case of a prospectus, in the light of the circumstances under which they were made) not misleading. Notwithstanding anything to the contrary set forth herein, PubCo shall not, when so advising Subscriber of such events, provide Subscriber with any material, non-public information regarding PubCo. At its expense, PubCo shall use its commercially reasonable efforts to obtain the withdrawal of any order suspending the effectiveness of any Registration Statement as soon as reasonably practicable, and upon the occurrence of any event contemplated above (other than a permitted Suspension Event), PubCo shall use its commercially reasonable efforts to, as soon as reasonably practicable, prepare a post-effective amendment to such Registration Statement or a supplement to the related prospectus, or file any other required document so that, as thereafter delivered to purchasers of the Subscribed Securities included therein, such prospectus will not include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading.

(f) Upon receipt of written notice from PubCo of the happening of any Suspension Event 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, the undersigned agrees that (1) it will immediately discontinue offers and sales of the Subscribed Securities under the Registration Statement (excluding, for the avoidance of doubt, sales conducted pursuant to Rule 144) until the undersigned receives copies of a supplemental or amended prospectus (which PubCo 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 PubCo that it may resume such offers and sales, and (2) it will maintain the confidentiality of any information included in such written notice delivered by PubCo unless otherwise required by law, subpoena or regulatory request or requirement. If so directed by PubCo, the undersigned will deliver to PubCo or, in the undersigned’s sole discretion, destroy all copies of the prospectus covering the Subscribed Securities in the undersigned’s possession; provided, however, that this obligation to deliver or destroy all copies of the prospectus covering the Subscribed Securities shall not apply (x) to the extent the undersigned is required to retain a copy of such prospectus (A) in order 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 (y) to copies stored electronically on archival servers as a result of automatic data back-up.

(g) For purposes of this Section 5, “Subscribed Securities” shall mean, as of any date of determination, the Subscribed Securities (as defined in the recitals to this Subscription Agreement) and any other equity security issued or issuable with respect to the Subscribed Securities by way of share split, dividend, distribution, recapitalization, merger, exchange, replacement or similar event, and “Subscriber” shall include any affiliate of the undersigned Subscriber to which the rights under this Section 5 shall have been duly assigned.

(h) PubCo shall indemnify and hold harmless Subscriber (to the extent a seller under the Registration Statement), its officers, directors and agents, trustees, partners, members, managers, stockholders, affiliates, employees, employees of its investment manager or advisors, investment manager or advisors and each person who controls 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 reasonable and documented 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 preliminary prospectus, or in any amendment or supplement thereto, 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 any form of prospectus or preliminary prospectus, or any amendment or supplement thereto, in light of the circumstances under which they were made) not misleading, except to the extent, that such Losses arise out of, or are based upon, any untrue statements, alleged untrue statements, omissions or alleged omissions were made in reliance upon and in conformity with any information regarding Subscriber furnished in writing to PubCo by Subscriber expressly for use therein.

(i) Subscriber shall indemnify and hold harmless PubCo, its directors, officers, agents and employees, each person who controls PubCo (within the meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act), and the directors, officers, agents or employees of such controlling persons, to the fullest extent permitted by applicable law, from and against all 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 any form of prospectus or preliminary prospectus, or in any amendment or supplement thereto, 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 any form of prospectus or preliminary prospectus, or any amendment or supplement thereto, in light of the circumstances under which they were made) not misleading, but only to the extent that such Losses arise out of, or are based upon, any untrue statements, alleged untrue statements, omissions or alleged omissions were made in reliance upon and in conformity with any information regarding Subscriber furnished in writing to PubCo by Subscriber expressly for use therein. In no event shall the liability of Subscriber be greater in amount than the dollar amount of the net proceeds received by Subscriber upon the sale of the Subscribed Securities giving rise to such indemnification obligation. Subscriber shall notify PubCo promptly of the institution, threat or assertion of any proceeding arising from or in connection with the transactions contemplated by this Section 5 of which Subscriber is aware.

(j) Any person or entity entitled to indemnification herein shall (A) give prompt written notice to the indemnifying party of any claim with respect to which it seeks indemnification (provided that the failure to give prompt notice shall not impair any person’s or entity’s right to indemnification hereunder to the extent such failure has not prejudiced the indemnifying party) and (B) unless in such indemnified party’s reasonable judgment a conflict of interest between such indemnified and indemnifying parties may exist with respect to such claim, permit such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party. If such defense is assumed, the indemnifying party shall not be subject to any liability for any settlement made by the indemnified party without its consent (but such consent shall not be unreasonably withheld, conditioned or delayed). An indemnifying party who is not entitled to, or elects not to, assume the defense of a claim shall not be obligated to pay the fees and expenses of more than one counsel for all parties indemnified by such indemnifying party with respect to such claim, unless in the reasonable judgment of any indemnified party a conflict of interest may exist between such indemnified party and any other of such indemnified parties with respect to such claim. No indemnifying party shall, without the consent of the indemnified party, consent to the entry of any judgment or enter into any settlement which cannot be settled in all respects by the payment of money (and such money is so paid by the indemnifying party pursuant to the terms of such settlement) or which settlement includes a statement or admission of fault and culpability on the part of such indemnified party or which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect to such claim or litigation.

(k) If the indemnification provided under this Section 5 from the indemnifying party is unavailable or insufficient to hold harmless an indemnified party in respect of any Losses referred to herein, then the indemnifying party, in lieu of indemnifying the indemnified party, shall contribute to the amount paid or payable by the indemnified party as a result of such Losses in such proportion as is appropriate to reflect the relative fault of the indemnifying party and the indemnified party, as well as any other relevant equitable considerations. The relative fault of the indemnifying party and indemnified party shall be determined by reference to, among other things, whether any action in question, including any untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact, was made by, or relates to information supplied by, such indemnifying party or indemnified party, and the indemnifying party’s and indemnified party’s relative intent, knowledge, access to information and opportunity to correct or prevent such action. The amount paid or payable by a party as a result of the Losses referred to above shall be deemed to include, subject to the limitations set forth in this Section 5, any legal or other fees, charges or expenses reasonably incurred by such party in connection with any investigation or proceeding. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution pursuant to this Section 5(k) from any person who was not guilty of such fraudulent misrepresentation. Each indemnifying party’s obligation to make a contribution pursuant to this Section 5(k) shall be individual, not joint and several, and in no event shall the liability of any Subscriber hereunder be greater in amount than the dollar amount of the net proceeds received by such Subscriber upon the sale of the Subscribed Securities giving rise to such indemnification obligation.

6. Other Covenants.

(a) With a view to making available to Subscriber the benefits of Rule 144 promulgated under the Securities Act or any other similar rule or regulation of the Commission that may at any time permit Subscriber to sell securities of PubCo to the public without registration, PubCo agrees, until Subscriber no longer holds Subscribed Securities, to use commercially reasonable efforts to:

(i) make and keep public information available, as those terms are understood and defined in Rule 144;

(ii) file with the Commission in a timely manner all reports and other documents required of PubCo under the Securities Act and the Exchange Act so long as PubCo remains subject to such requirements and the filing of such reports and other documents is required for the applicable provisions of Rule 144; and

(iii) furnish to Subscriber so long as it owns Subscribed Securities, as promptly as practicable upon request, (x) a written statement by PubCo, if true, that it has complied with the reporting requirements of Rule 144, the Securities Act and the Exchange Act, and (y) such other information as may be reasonably requested to permit Subscriber to sell such securities pursuant to Rule 144 without registration.

(b) If requested by Subscriber, PubCo shall use its commercially reasonable efforts to cause the removal of the Restricted Legend from:

(i) any Subscribed Securities being sold by Subscriber under the Registration Statement so long as the Registration Statement is effective and no stop order or Suspension Event is in effect;

(ii) any Subscribed Securities being sold by Subscriber under Rule 144 so long as such sale complies with Rule 144 in all respects (and Subscriber certifies to PubCo of such compliance) and PubCo is in compliance with the current public information required by Rule 144(c)(1) and with Rule 144(i)(2), if applicable; or

(iii) all of Subscriber’s Subscribed Securities so long as all of its Subscribed Securities may be sold by Subscriber under Rule 144 without any volume and manner of sale restrictions (and Subscriber certifies to PubCo accordingly) without the requirement for PubCo to be in compliance with the current public information required by Rule 144(c)(1), and PubCo is in compliance with Rule 144(i)(2), if applicable.

To the extent required by the Transfer Agent, PubCo shall use commercially reasonable efforts to cause its legal counsel to deliver a customary opinion within two Business Days of the delivery of all reasonably necessary representations and other documentation from Subscriber as reasonably requested by PubCo, its counsel or the Transfer Agent by Subscriber to the Transfer Agent to the effect that the removal of the Restricted Legend in such circumstances may be effected under the Securities Act.

(c) Subscriber hereby agrees that, from the date of this Subscription Agreement, none of Subscriber, its controlled affiliates, or any person or entity acting on behalf of Subscriber or any of its controlled affiliates or pursuant to any understanding with Subscriber or any of its controlled affiliates will engage in any Short Sales with respect to securities of PubCo prior to the Closing. Notwithstanding the foregoing, (i) nothing herein shall prohibit other entities under common management with Subscriber that have no knowledge of this Subscription Agreement or of Subscriber’s participation in the Transaction (including Subscriber controlled affiliates and/or affiliates) from entering into any Short Sales and (ii) in the case of a Subscriber that is a multi-managed investment vehicle whereby separate portfolio managers manage separate portions of such Subscriber’s assets and the portfolio managers have no knowledge of the investment decisions made by the portfolio managers managing other portions of such Subscriber’s assets, this Section 6(c) shall only apply with respect to the portion of assets managed by the portfolio manager that made the investment decision to purchase the Purchase Price covered by this Subscription Agreement.

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 Agreement is terminated in accordance with its terms, (b) upon the mutual written agreement of PAAC or PubCo, as applicable, Subscriber and Astro Digital to terminate this Subscription Agreement, (c) the event that any conditions contained in Section 2 herein are not satisfied on or prior to the Closing and, as a result thereof, the Subscription and the other transactions contemplated by this Subscription Agreement are not or will not be consummated at the Closing; or (d) the “Outside Closing Date”, as defined in the Agreement, if the Closing has not occurred by such date; provided, however, that nothing herein will relieve any party hereto from liability for any willful breach hereof prior to the time of termination, and each party hereto will be entitled to any remedies at law or in equity to recover losses, liabilities or damages arising from such breach. PAAC or PubCo shall notify Subscriber of the termination of the Agreement promptly after the termination thereof. For the avoidance of doubt, if this Subscription Agreement terminates following the delivery by Subscriber of the Purchase Price, PubCo shall instruct the escrow agent hereunder to promptly (but not later than two Business Days thereafter) return the Purchase Price to Subscriber, whether or not the closing of the Transaction shall have occurred. For purposes of this Section 7, “willful breach” shall mean a material breach of this Subscription Agreement that is a consequence of an act or omission by the breaching party with the actual knowledge that such act or omission would, or would reasonably be expected to, constitute a breach of this Subscription Agreement, including, without limitation, Subscriber’s failure or refusal to deliver the Purchase Price at the Closing when all conditions to Subscriber’s obligation to consummate the Closing have been satisfied or waived.

8. Trust Account Waiver. Subscriber hereby acknowledges that PAAC 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 PAAC’s public stockholders and certain other parties (including the underwriters of the IPO). For and in consideration of PAAC 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 PAAC, and (iii) will not seek recourse against the Trust Account for any reason whatsoever; provided however, that nothing in this Section 8 shall (a) be deemed to limit any Subscriber’s right to distributions from the Trust Account by virtue of Subscriber’s record of beneficial ownership of PAAC’s or PubCo’s shares of common stock, (b) be deemed to limit subscriber’s right to exercise any redemption rights with respect to of PAAC’s or PubCo’s shares of common stock owned by Subscriber, (c) serve to limit or prohibit Subscriber’s right to pursue a claim against PAAC for legal relief against assets held outside the Trust Account, for specific performance or other equitable relief, or (d) serve to limit or prohibit any claims that Subscriber may have in the future against PAAC’s assets or funds that are not held in the Trust Account.

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, (iii) one Business Day after being sent to the recipient by reputable overnight courier service (charges prepaid), or (iv) four 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).

(b) Subscriber acknowledges that PAAC will rely on the acknowledgments, understandings, agreements, representations and warranties contained in this Subscription Agreement. Prior to the Closing, Subscriber agrees to promptly notify PAAC if it becomes aware that any of the acknowledgments, understandings, agreements, representations and warranties of Subscriber set forth herein are no longer accurate in all material respects (unless qualified by materiality or “material adverse effect,” in which case are no longer accurate in all respects). PAAC acknowledges that Subscriber and others will rely on the acknowledgments, understandings, agreements, representations and warranties contained in this Subscription Agreement. Prior to the Closing, PAAC agrees to promptly notify Subscriber if it becomes aware that any of the acknowledgments, understandings, agreements, representations and warranties of PAAC set forth herein are no longer accurate in all material respects (unless qualified by materiality or “material adverse effect,” in which case are no longer accurate in all respects).

(c) Each of PAAC, Astro Digital 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) Each of PAAC and Subscriber shall pay all of its own expenses in connection with this Subscription Agreement and the transactions contemplated herein.

(e) PAAC shall be responsible for the fees of its transfer agent, stamp taxes and all of the Depository Trust Company’s fees associated with the issuance of the Subscribed Securities.

(f) Neither this Subscription Agreement nor any rights that may accrue to Subscriber hereunder (other than the Subscribed Securities acquired hereunder, if any) may be transferred or assigned. Except as otherwise provided herein, neither this Subscription Agreement nor any rights that may accrue to PAAC hereunder may be transferred or assigned; provided, that, PAAC may, without the prior written consent of Subscriber, transfer or assign its rights and obligations under this Subscription Agreement to PubCo in connection with the consummation of the Transaction. Notwithstanding the foregoing, Subscriber may assign its rights and obligations under this Subscription Agreement without PAAC’s or Astro Digital’s prior written consent to one or more of its affiliates or to any fund or account managed by the same investment adviser as Subscriber, or by an affiliate of such investment adviser, or, with PubCo’s and Astro Digital’s prior written consent, to another person; provided that no such assignment shall relieve Subscriber of its obligations hereunder regardless of whether any such assignee performs such obligations; provided further that any such assignee shall independently satisfy the requirements of Section 4(d) and shall execute and deliver to PAAC and Astro Digital a joinder agreement making the representations and warranties of Subscriber set forth herein.

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

(h) PAAC or PubCo may request from Subscriber such additional information as it may deem reasonably necessary to evaluate the eligibility of Subscriber to acquire the Subscribed Securities, 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; provided that PAAC and PubCo expressly agrees to keep any such information provided by Subscriber confidential, except (i) as required by law, subpoena or regulatory request or requirement or (ii) to the extent such disclosure is required by law, at the request of the staff of the Commission or regulatory agency or under the regulations of any national securities exchange on which PAAC or PubCo’s securities are listed for trading. The Subscriber acknowledges and agrees that if it does not provide PAAC or PubCo, as applicable, with such requested information, PAAC or PubCo may not be able to register the Subscriber’s Subscribed Securities for resale pursuant to Section 5 hereof. The Subscriber hereby agrees that its identity and the Subscription Agreement, as well as the nature of the Subscriber’s obligations hereunder, may be disclosed in any public announcement or disclosure required by the Commission and in any registration statement, proxy statement, consent solicitation statement or any other Commission filing to be filed by PAAC or PubCo in connection with the issuance of Shares contemplated by this Subscription Agreement and/or the Transaction.

(i) This Subscription Agreement may not be amended, modified, waived or terminated (other than pursuant to the terms of Section 7 above) except by an instrument in writing, signed by each of the parties hereto; provided, however, that no amendment, modification or waiver of any provision of this Subscription Agreement shall be effective without the prior written consent of Astro Digital if such amendment, modification or waiver would (A) reduce the number or change the type of Subscribed Securities to be purchased hereunder, reduce the Per Share Price or the Purchase Price, (B) amend, modify or waive any provision of this Subscription Agreement that confers rights on Astro Digital as a third-party beneficiary, (C) amend, modify or waive any of the conditions to the Closing set forth in Section 2(e), Section 2(f) or Section 2(g), (D) amend, modify or waive the representations and warranties set forth in Section 4(f) or Section 4(m) or (E) amend, modify or waive any provision of Section 7 or this Section 9. No failure or delay of either party in exercising any right or remedy hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps to enforce such right or power, or any course of conduct, preclude any other or further exercise thereof or the exercise of any other right or power. The rights and remedies of the parties hereunder are cumulative and are not exclusive of any rights or remedies that they would otherwise have hereunder.

(j) This Subscription Agreement, together with Annex A and the other documents and certificates delivered pursuant hereto, constitutes the entire agreement, and supersedes all other prior agreements, understandings, representations and warranties, both written and oral, among the parties hereto, with respect to the subject matter hereof.

(k) Except as otherwise provided herein, this Subscription Agreement shall be binding upon, and inure to the benefit of the parties hereto and their heirs, executors, administrators, successors, legal representatives, and permitted assigns, and the agreements, representations, warranties, covenants and acknowledgments contained herein shall be deemed to be made by, and be binding upon, such heirs, executors, administrators, successors, legal representatives and permitted assigns.

(l) If any provision of this Subscription Agreement shall be invalid, illegal or unenforceable, the validity, legality or enforceability of the remaining provisions of this Subscription Agreement shall not in any way be affected or impaired thereby and shall continue in full force and effect.

THE PARTIES HERETO 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 HERETO 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 hereto 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 hereto 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. Each of the parties hereto also agrees that delivery of any process, summons, notice or document to a party hereof in compliance with Section 9(a) above shall be effective service of process for any action, suit or proceeding in a Designated Court with respect to any matters to which the parties hereto have submitted to jurisdiction as set forth above.

(s) PAAC has disclosed to Subscriber certain non-public information regarding the Transaction, including the material terms of the transactions contemplated hereby (and by the Other Subscription Agreements), and Subscriber acknowledges its agreement to treat such information confidentially until such time as all such “material non-public information” (within the meaning of applicable securities laws) is either publicly disclosed by PAAC (including as contemplated by the following sentence) or deemed by PAAC to be no longer relevant. In accordance therewith, PAAC shall, by 9:00 a.m., New York City time, on the first Business Day immediately following the date of this Subscription Agreement, issue one or more press releases or file with the Commission a Current Report on Form 8-K disclosing, to the extent not previously publicly disclosed, such material non-public information unless PAAC determines, in compliance with applicable laws and regulations, that any of such information is no longer material. Notwithstanding anything in this Subscription Agreement to the contrary, PAAC shall not publicly disclose the name of Subscriber, its investment adviser or any of their respective affiliates, or include the name of Subscriber, its investment adviser or any of their respective affiliates in any press release or in any filing with the Commission or any regulatory agency or trading market, without the prior written consent (including by e-mail) of Subscriber, except as required by the federal securities laws, rules or regulations and to the extent such disclosure is required by other laws, rules or regulations, at the request of the staff of the Commission or regulatory agency or under Nasdaq regulations, in which case PAAC shall provide Subscriber with prior written notice (including by e-mail) of such permitted disclosure, and shall reasonably consult with Subscriber regarding such disclosure.

(t) The obligations of Subscriber under this Subscription Agreement are several and not joint with the obligations of any Other Subscriber or any other investor under the Other Subscription Agreements, and Subscriber shall not be responsible in any way for the performance of the obligations of any Other Subscriber under this Subscription Agreement or any other investor under the Other Subscription Agreements. 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 Subscriber and other investors as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that 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 Subscriber in connection with making its investment hereunder and no Other Subscriber will be acting as agent of Subscriber in connection with monitoring its investment in the Subscribed Securities 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.

(u) Subscriber understands and agrees that Subscriber is purchasing the Subscribed Securities directly from PubCo. Subscriber further acknowledges that there have not been, and Subscriber hereby agrees that it is not relying on, any representations, warranties, covenants or agreements made to Subscriber by PAAC, PubCo, Astro Digital and its affiliates, any other party to the Transaction, any of the foregoing person’s Representatives or any other person or entity, expressly or by implication, other than those representations, warranties, covenants and agreements of PAAC set forth in this Subscription Agreement. Subscriber acknowledges that certain information provided by PAAC was based on projections, and such projections were prepared 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.
