THIS AMENDED AND RESTATED PUBLIC WARRANT AGREEMENT (this “Agreement”), dated as of October 1, 2026, is by and between NorthStar Earth & Space Enterprises, Inc. (the “Company”), a corporation existing under the Canada Business Corporations Act (the “CBCA”), and Continental Stock Transfer & Trust Company, a New York corporation, as warrant agent (the “Warrant Agent,” also referred to herein as the “Transfer Agent”).

WHEREAS, the Company previously consummated its initial public offering (the “Offering”) of units (each, a “Unit”) of the Company’s equity securities, each Unit comprised of one consisting of one Class A ordinary share of the Company, par value $0.0001 per share (each, an “Ordinary Share”) and one warrant to purchase one-third of an Ordinary Share to public investors in the Offering (each, a “Public Warrant”); and

WHEREAS, the Company (then known as Viking Acquisition Corp. I, a Cayman Islands exempted company (“Viking”)) previously entered into that certain Public Warrant Agreement, dated October 30, 2025 (the “Original Agreement”), with the Warrant Agent; and

WHEREAS, pursuant to the Business Combination Agreement, dated as of April 16, 2026 (as amended, the “Business Combination Agreement”), by and among Viking, NorthStar Earth & Space Inc., a corporation existing under the CBCA (“NorthStar”), and Viking NS Amalgamation Corp., a corporation existing under the CBCA and a wholly-owned direct subsidiary of Viking (“NewCo”), the parties thereto consummated a business combination (the “Business Combination”), pursuant to which, among other things, (i) Viking continued as a corporation existing under the CBCA, and in connection therewith, changed its corporate name to “NorthStar Earth & Space Enterprises, Inc.”, (ii) promptly following the such continuation, the Company, NorthStar and NewCo effected an arrangement under Section 192 of the CBCA (the “Arrangement”) in accordance with the plan of arrangement (the “Plan of Arrangement”), pursuant to which, among other things, NewCo and NorthStar amalgamated (the “Amalgamation”) to form one corporate entity and NewCo survived the Amalgamation as a wholly owned subsidiary of the Company; and

WHEREAS, simultaneously with its entry into the Business Combination, Viking and NorthStar entered into Securities Purchase Agreements (the “PIPE Agreements”) with institutional investors, pursuant to which, among other things, immediately prior to the Amalgamation, such investors were issued warrants of NorthStar (the “NorthStar Warrants”) which each NorthStar Warrant converted, upon the Amalgamation and pursuant to the Plan of Arrangement, on a one-to-one basis into a warrant to acquire one common share of the Company (“Common Share”) governed by the terms of this Agreement (the “PIPE Warrants” and, together with the Public Warrants, the “Warrants”) and bearing the legend set forth on Exhibit A hereto; and

WHEREAS, in connection with the closing of the Business Combination, each outstanding Unit separated into its component securities; and

WHEREAS, as of immediately prior to the Amalgamation, (i) Viking had outstanding an aggregate of 7,666,645 Public Warrants and (ii) NorthStar had outstanding an aggregate of 115,294 NorthStar Warrants; and

WHEREAS, upon the Amalgamation, the Public Warrants will automatically converted by operation of law into warrants to purchase Common Shares; and

WHEREAS, each Warrant entitles the holder thereof to purchase one Common Share for $11.50 per share, subject to adjustment as described herein; and

WHEREAS, the Company has filed with the U.S. Securities and Exchange Commission (the “Commission”) a registration statement on Form F-4 (File No. 333-297008) and a proxy statement/prospectus (as amended from time to time, the “Registration Statement”) for the registration, under the Securities Act of 1933, as amended (the “Securities Act”), of the Public Warrants and the Common Shares issuable upon exercise of the Public Warrants; and

WHEREAS, in connection with the Business Combination, the Company and the Warrant Agent desire to amend and restate the Original Agreement; and

WHEREAS, the Company desires the Warrant Agent to act on behalf of the Company, and the Warrant Agent is willing to so act, in connection with the issuance, registration, transfer, exchange, redemption and exercise of the Warrants; and

WHEREAS, the Company desires to provide for the form and provisions of the Warrants, the terms upon which they shall be issued and exercised, and the respective rights, limitation of rights and immunities of the Company, the Warrant Agent and the holders of the Warrants; and

WHEREAS, all acts and things have been done and performed which are necessary to make the Warrants, when executed on behalf of the Company and countersigned by or on behalf of the Warrant Agent (if a physical certificate is issued), as provided herein, the valid, binding and legal obligations of the Company, and to authorize the execution and delivery of this Agreement.

NOW, THEREFORE, in consideration of the mutual agreements herein contained, the parties hereto agree as follows:

1. Appointment of Warrant Agent. The Company hereby appoints the Warrant Agent to act as agent for the Company for the Warrants, and the Warrant Agent ▇▇▇▇▇▇ accepts such appointment and agrees to perform the same in accordance with the terms and conditions set forth in this Agreement.

2. Warrants.

2.1 Form of Warrant. Each Warrant shall be issued in registered form only.

2.2 Effect of Countersignature. If a physical certificate is issued, unless and until countersigned by the Warrant Agent pursuant to this Agreement, a certificated Warrant shall be invalid and of no effect and may not be exercised by the holder thereof.

2.3 Registration.

2.3.1 Warrant Register. The Warrant Agent shall maintain books (the “Warrant Register”) for the registration of the initial issuance of the Warrants and the registration of transfer of the Warrants. Upon the initial issuance of the Warrants in book-entry form, the Warrant Agent shall issue and register the Warrants in the names of the respective holders thereof in such denominations and otherwise in accordance with instructions delivered to the Warrant Agent by the Company. Ownership of beneficial interests in the Warrants shall be shown on, and the transfer of such ownership shall be effected through, records maintained by institutions that have accounts with The Depository Trust Company (the “Depository”) (such institution, with respect to a Warrant in its account, a “Participant”). If the Depository subsequently ceases to make its book-entry settlement system available for the Warrants, the Company may instruct the Warrant Agent regarding making other arrangements for book-entry settlement. In the event that the Warrants are not eligible for, or it is no longer necessary to have the Warrants available in, book-entry form, the Warrant Agent shall provide written instructions to the Depository to deliver to the Warrant Agent for cancellation each book-entry Warrant, and the Company shall instruct the Warrant Agent to deliver to the Depository definitive certificates in physical form evidencing such Warrants which shall be in the form attached hereto as Exhibit B. Physical certificates, if issued, shall be signed by, or bear the facsimile signature of, the Chairman of the board of directors of the Company (the “Board”), Chief Executive Officer, Chief Financial Officer, Secretary or other principal officer of the Company. In the event the person whose facsimile signature has been placed upon any Warrant shall have ceased to serve in the capacity in which such person signed the Warrant before such Warrant is issued, it may be issued with the same effect as if he or she had not ceased to be such at the date of issuance.

2.3.2 Registered Holder. Prior to due presentment for registration of transfer of any Warrant, the Company and the Warrant Agent may deem and treat the person in whose name such Warrant is registered in the Warrant Register (the “Registered Holder”) as the absolute owner of such Warrant and of each Warrant represented thereby (notwithstanding any notation of ownership or other writing on any physical certificate made by anyone other than the Company or the Warrant Agent), for the purpose of any exercise thereof, and for all other purposes, and neither the Company nor the Warrant Agent shall be affected by any notice to the contrary.

2.4 [Reserved].

2.5 No Fractional Warrants. The Company shall not issue fractional Warrants.

3. Terms and Exercise of Warrants.

3.1 Warrant Price. Each whole Warrant shall entitle the Registered Holder thereof, subject to the provisions of such Warrant and of this Agreement, to purchase from the Company the number of Common Shares stated therein, at the price of $11.50 per share, subject to the adjustments provided in Section 4 hereof and in the last sentence of this Section 3.1. The term “Warrant Price” as used in this Agreement shall mean the price per share at which Common Shares may be purchased at the time a Warrant is exercised. The Company in its sole discretion may lower the Warrant Price at any time prior to the Expiration Date (as defined below) for a period of not less than twenty (20) Business Days (for the purposes of this Agreement, a “Business Day” shall mean any day other than a Saturday, Sunday or federal holiday on which banks in New York City are generally open for normal business), provided that the Company shall provide at least twenty (20) days prior written notice of such reduction to Registered Holders of the Warrants and, provided further that any such reduction shall be identical among all of the Warrants.

3.2 Duration of Warrants. A Warrant may be exercised only during the period (the “Exercise Period”) commencing on the date that is thirty (30) days after the date of this Agreement and terminating at the earlier to occur of: (x) 5:00 p.m., New York City time on the date that is five (5) years after the date of this Agreement, (y) the liquidation of the Company, or (z) 5:00 p.m., New York City time on the Redemption Date (as defined below) as provided in Section 6.2 hereof (the “Expiration Date”); provided, however, that the exercise of any Warrant shall be subject to the satisfaction of any applicable conditions, as set forth in Section 3.3.2 hereof, with respect to an effective registration statement. Except with respect to the right to receive the Redemption Price (as defined below), in the event of a redemption (as set forth in Section 6 hereof), each Warrant not exercised on or before the Expiration Date shall become null and void, and all rights thereunder and all rights in respect thereof under this Agreement shall cease at 5:00 p.m., New York City time on the Expiration Date. The Company in its sole discretion may extend the duration of the Warrants by delaying the Expiration Date; provided that the Company shall provide at least twenty (20) days prior written notice of any such extension to Registered Holders of the Warrants and, provided further that any such extension shall be identical in duration among all the Warrants.

3.3 Exercise of Warrants.

3.3.1 Payment. Subject to the provisions of the Warrant and this Agreement, a Warrant may be exercised by the Registered Holder thereof by delivering it to the Warrant Agent at its corporate trust department with the election to purchase form, as set forth on the reverse of the Warrant, duly executed, and by paying in full the Warrant Price for each full Common Share as to which the Warrant is exercised and any and all applicable taxes due in connection with the exercise of the Warrant, the exchange of the Warrant for the Common Shares and the issuance of such Common Shares, as follows:

(a) in lawful money of the United States, by wire transfer, in good certified check or good bank draft payable to the Warrant Agent, provided that there is an effective registration statement covering the Common Shares issuable upon exercise of the Warrants, and a current prospectus relating thereto, available;

(b) in the event of a redemption pursuant to Section 6 hereof in which the Board has elected to require all holders of the Warrants to exercise such Warrants on a “cashless basis,” by surrendering the Warrants for that number of Common Shares equal to the quotient obtained by dividing (x) the product of the number of Common Shares underlying the Warrants, multiplied by the excess of the “Fair Market Value”, as defined in this Section 3.3.1(b), over the Warrant Price by (y) the Fair Market Value. Solely for purposes of this Section 3.3.1(b) and Section 6.1, the “Fair Market Value” shall mean the 10-Day Average Closing Price as of the date on which the notice of redemption is sent to the holders of the Warrants, pursuant to Section 6 hereof; the “10-Day Average Closing Price” means, as of any date, the average last reported sale price of the Common Shares as reported during the ten (10) trading day period ending on the trading day prior to such date. The “last reported sale price” shall mean the last reported sale price of the Common Shares on the date prior to the date on which an event which requires such determination has occurred; or

3.3.2 Issuance of Common Shares on Exercise. As soon as practicable after the exercise of any Warrant and the clearance of the funds in payment of the Warrant Price (if payment is pursuant to Section 3.3.1(a) hereof), the Company shall issue to the Registered Holder of such Warrant a book-entry position or certificate, as applicable, for the number of full Common Shares to which he, she or it is entitled, registered in such name or names as may be directed by him, her or it, and if such Warrant shall not have been exercised in full, a new book-entry position or countersigned Warrant, as applicable, for the number of Common Shares as to which such Warrant shall not have been exercised. Notwithstanding the foregoing, the Company shall not be obligated to deliver any Common Shares pursuant to the exercise of a Warrant and shall have no obligation to settle such Warrant exercise unless a registration statement under the Securities Act with respect to the Common Shares underlying the Warrants is then effective and a prospectus relating thereto is current or a valid exemption from registration is available. No Warrant shall be exercisable and the Company shall not be obligated to issue Common Shares upon exercise of a Warrant unless the Common Share issuable upon such Warrant exercise has been registered, qualified or deemed to be exempt from registration or qualification under the securities laws of the state of residence of the Registered Holder of the Warrants. In the event that the conditions in the two immediately preceding sentences are not satisfied with respect to a Warrant, the holder of such Warrant shall not be entitled to exercise such Warrant. In no event will the Company be required to net cash settle the Warrant exercise. The Company may require holders of Warrants to settle the Warrant on a “cashless basis” pursuant to Section 7.4.2 hereof. If, by reason of any exercise of Warrants on a “cashless basis,” the holder of any Warrant would be entitled, upon the exercise of such Warrant, to receive a fractional interest in a Common Share, the Company shall round down to the nearest whole number the number of Common Shares to be issued to such holder.

3.3.3 Valid Issuance. All Common Shares issued upon the proper exercise of a Warrant in conformity with this Agreement shall be validly issued, fully paid and non-assessable.

3.3.4 Date of Issuance. Each person in whose name any book-entry position or certificate, as applicable, for Common Shares is issued shall for all purposes be deemed to have become the holder of record of such Common Shares on the date on which the Warrant, or book-entry position representing such Warrant, was surrendered and payment of the Warrant Price was made, irrespective of the date of delivery of such certificate in the case of a certificated Warrant, except that, if the date of such surrender and payment is a date when the share transfer books of the Company or book-entry system of the Warrant Agent are closed, such person shall be deemed to have become the holder of such Common Shares at the close of business on the next succeeding date on which the share transfer books of the Company or book-entry system of the Warrant Agent are open.

3.3.5 Maximum Percentage. A holder of a Warrant may notify the Company in writing in the event it elects to be subject to the provisions contained in this Section 3.3.5; however, no holder of a Warrant shall be subject to this Section 3.3.5 unless he, she or it makes such election. If the election is made by a holder, the Warrant Agent shall not effect the exercise of the holder’s Warrant, and such holder shall not have the right to exercise such Warrant, to the extent that after giving effect to such exercise, such person (together with such person’s affiliates), to the Warrant Agent’s actual knowledge, would beneficially own in excess of 9.8%, or such other amount as a holder may specify (the “Maximum Percentage”) of the Common Shares outstanding immediately after giving effect to such exercise. For purposes of the foregoing sentence, the aggregate number of Common Shares beneficially owned by such person and its affiliates shall include the number of Common Shares issuable upon exercise of the Warrant with respect to which the determination of such sentence is being made, but shall exclude Common Shares that would be issuable upon (x) exercise of the remaining, unexercised portion of the Warrant beneficially owned by such person and its affiliates and (y) exercise or conversion of the unexercised or unconverted portion of any other securities of the Company beneficially owned by such person and its affiliates (including, without limitation, any convertible notes or convertible preferred shares or warrants) subject to a limitation on conversion or exercise analogous to the limitation contained herein. Except as set forth in the preceding sentence, for purposes of this paragraph, beneficial ownership shall be calculated in accordance with Section 13(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). For purposes of the Warrant, in determining the number of outstanding Common Shares, the holder may rely on the number of outstanding Common Shares as reflected in (1) the Company’s most recent Annual Report on Form 10-K, Quarterly Report on Form 10-Q, Current Report on Form 8-K or other public filing with the Commission as the case may be, (2) a more recent public announcement by the Company or (3) any other notice by the Company or the Transfer Agent setting forth the number of Common Shares outstanding. For any reason at any time, upon the written request of the holder of the Warrant, the Company shall, within two (2) Business Days, confirm orally and in writing to such holder the number of Common Shares then outstanding. In any case, the number of issued and outstanding Common Shares shall be determined after giving effect to the conversion or exercise of equity securities of the Company by the holder and its affiliates since the date as of which such number of issued and outstanding Common Shares was reported. By written notice to the Company, the holder of a Warrant may from time to time increase or decrease the Maximum Percentage applicable to such holder to any other percentage specified in such notice; provided, however, that any such increase shall not be effective until the sixty-first (61st) day after such notice is delivered to the Company.

4. Adjustments.

4.1 Share Dividends.

4.1.1 Subdivisions. If after the date hereof, and subject to the provisions of Section 4.6 hereof, the number of issued and outstanding Common Shares is increased by a share dividend payable in Common Shares, issuance of Common Shares by way of capitalization of reserves from a share premium account or capital redemption reserve or by a sub-division of Common Shares or other similar event, then, on the effective date of such share dividend, capitalization, sub-division or other similar event, the number of Common Shares issuable on exercise of each Warrant shall be increased in proportion to such increase in the issued and outstanding Common Shares. A rights offering to holders of the Common Shares entitling holders to purchase Common Shares at a price less than the “Fair Market Value” shall be deemed a share dividend of a number of Common Shares equal to the product of (i) the number of Common Shares actually sold in such rights offering (or issuable under any other equity securities sold in such rights offering that are convertible into or exercisable for Common Shares) multiplied by (ii) one (1) minus the quotient of (x) the price per Common Share paid in such rights offering divided by (y) the Fair Market Value. For purposes of this Section 4.1.1, if the rights offering is for securities convertible into or exercisable for Common Shares, in determining the price payable for such Common Shares, there shall be taken into account any consideration received for such rights, as well as any additional amount payable upon exercise or conversion. “Fair Market Value,” means the 10-Day Average Closing Price as of the first (1st) date on which the Common Shares trade on the applicable exchange or in the applicable market, regular way, without the right to receive such rights. Notwithstanding anything to the contrary herein, no Common Shares shall be issued at less than their par value (if any).

4.1.2 Extraordinary Dividends. If the Company, at any time while the Warrants are outstanding and unexpired, shall pay a dividend or make a distribution in cash, securities or other assets to the holders of the Common Shares on account of such Common Shares (or other shares of the Company into which the Warrants are convertible), other than (i) as described in Section 4.1.1 above, (ii) Ordinary Cash Dividends (as defined below), (iii) to satisfy the redemption rights of the holders of the Common Shares, or (iv) in connection with the distribution of the Company’s assets upon its liquidation (any such non-excluded event being referred to herein as an “Extraordinary Dividend”), then the Warrant Price shall be decreased, effective immediately after the effective date of such Extraordinary Dividend, by the amount of cash and/or the fair market value of any securities or other assets paid on each Common Share in respect of such Extraordinary Dividend. For purposes of this Section 4.1.2, “Ordinary Cash Dividends” means any cash dividend, cash distribution or distribution of Common Shares by way of capitalization from profit and loss account which, when combined on a per share basis, with the per share amounts of all other cash dividends, cash distributions and distributions of Common Shares by way of capitalization from profit and loss account paid or made on the Common Shares during the 365-day period ending on the date of declaration of such dividend or distribution (as adjusted to appropriately reflect any of the events referred to in other subsections of this Section 4 and excluding cash dividends, cash distributions or distributions of Common Shares by way of capitalization from profit and loss account that resulted in an adjustment to the Warrant Price or to the number of Common Shares issuable on exercise of each Warrant) does not exceed $0.50.

4.2 Aggregation of Shares. If after the date hereof, and subject to the provisions of Section 4.6 hereof, the number of issued and outstanding Common Shares is decreased by a consolidation, combination, reverse share sub-division or reclassification of Common Shares or other similar event, then, on the effective date of such consolidation, combination, reverse share sub-division, reclassification or similar event, the number of Common Shares issuable on exercise of each Warrant shall be decreased in proportion to such decrease in issued and outstanding Common Shares.

4.3 Adjustments in Exercise Price. Whenever the number of Common Shares purchasable upon the exercise of the Warrants is adjusted, as provided in Section 4.1.1 or Section 4.2 hereof, the Warrant Price shall be adjusted (to the nearest cent) by multiplying such Warrant Price immediately prior to such adjustment by a fraction (x) the numerator of which shall be the number of Common Shares purchasable upon the exercise of the Warrants immediately prior to such adjustment, and (y) the denominator of which shall be the number of Common Shares so purchasable immediately thereafter.

4.4 Replacement of Securities upon Reorganization, etc. In case of any reclassification or reorganization of the issued and outstanding Common Shares (other than a change covered by Sections 4.1.1, 4.1.2 or 4.2 hereof or that solely affects the par value (if any) of such Common Shares, or in the case of any merger or consolidation of the Company with or into another entity in which any “person” or “group” (as such terms are used in Sections 13(d) and 14(d) of the Exchange Act) acquires more than 50% of the voting power of the Company’s securities, or in the case of any sale or conveyance to another corporation or entity of the assets or other property of the Company as an entirety or substantially as an entirety), the holders of the Warrants shall thereafter have the right to purchase and receive, upon the basis and upon the terms and conditions specified in the Warrants and in lieu of the Common Shares of the Company immediately theretofore purchasable and receivable upon the exercise of the rights represented thereby, the kind and amount of shares or other securities or property (including cash) receivable upon such reclassification, reorganization, merger or consolidation, that the holder of the Warrants would have received if such holder had exercised his, her or its Warrant(s) immediately prior to such event (the “Alternative Issuance”). The provisions of this Section 4.4 shall similarly apply to successive reclassifications, reorganizations, mergers or consolidations, sales or other transfers. In no event will the Warrant Price be reduced to less than the par value (if any) per share issuable upon exercise of the Warrant.

4.5 Notices of Changes in Warrant. Upon every adjustment of the Warrant Price or the number of Common Shares issuable upon exercise of a Warrant, the Company shall give written notice thereof to the Warrant Agent, which notice shall state the Warrant Price resulting from such adjustment and the increase or decrease, if any, in the number of Common Shares purchasable at such price upon the exercise of a Warrant, setting forth in reasonable detail the method of calculation and the facts upon which such calculation is based; provided, however, that no adjustment to the number of Common Shares issuable upon exercise of a Warrant shall be required until cumulative adjustments amount to one percent (1%) or more of the number of Common Shares issuable upon exercise of a Warrant as last adjusted; provided, further, that any such adjustments that are not made are carried forward and taken into account in any subsequent adjustment. Notwithstanding the foregoing, all such carried forward adjustments shall be made (i) in connection with any subsequent adjustment that (taken together with such carried forward adjustments) would result in a change of at least one percent (1%) in the number of Common Shares issuable upon exercise of a Warrant and (ii) on the exercise date of any Warrant. Upon the occurrence of any event specified in Sections 4.1, 4.2, 4.3 or 4.4 hereof, the Company shall give written notice of the occurrence of such event to each holder of a Warrant, at the last address set forth for such holder in the Warrant Register, of the record date or the effective date of the event. Failure to give such notice, or any defect therein, shall not affect the legality or validity of such event.

4.6 No Fractional Shares. Notwithstanding any provision contained in this Agreement to the contrary, the Company shall not issue fractional Common Shares upon the exercise of Warrants. If, by reason of any adjustment made pursuant to this Section 4, the holder of any Warrant would be entitled, upon the exercise of such Warrant, to receive a fractional interest in a share, the Company shall, upon such exercise, round down to the nearest whole number of Common Shares to be issued to such holder.

4.7 Form of Warrant. The form of Warrant need not be changed because of any adjustment pursuant to this Section 4, and Warrants issued after such adjustment may state the same Warrant Price and the same number of Common Shares as is stated in the Warrants initially issued pursuant to this Agreement; provided, however, that the Company may at any time in its sole discretion make any change in the form of Warrant that the Company may deem appropriate and that does not affect the substance thereof, and any Warrant thereafter issued or countersigned, whether in exchange or substitution for an outstanding Warrant or otherwise, may be in the form as so changed.

5. Transfer and Exchange of Warrants.

5.1 Registration of Transfer. The Warrant Agent shall register the transfer, from time to time, of any outstanding Warrant upon the Warrant Register, upon surrender of such Warrant for transfer, in the case of a certificated Warrant, properly endorsed with signatures properly guaranteed and accompanied by appropriate instructions for transfer. Upon any such transfer, a new Warrant representing an equal aggregate number of Warrants shall be issued and the old Warrant shall be cancelled by the Warrant Agent. In the case of certificated Warrants, the Warrants so cancelled shall be delivered by the Warrant Agent to the Company from time to time upon request.

5.2 Procedure for Surrender of Warrants. Warrants may be surrendered to the Warrant Agent, together with a written request for exchange or transfer, and thereupon the Warrant Agent shall issue in exchange therefor one or more new Warrants as requested by the Registered Holder of the Warrants so surrendered, representing an equal aggregate number of Warrants; provided, however, that in the event that a Warrant surrendered for transfer bears a restrictive legend, the Warrant Agent shall not cancel such Warrant and issue new Warrants in exchange thereof until the Warrant Agent has received an opinion of counsel for the Company stating that such transfer may be made and indicating whether the new Warrants must also bear a restrictive legend.

5.3 Transfers of Fractions of Warrants. The Warrant Agent shall not be required to effect any registration of transfer or exchange of Warrants which would require the issuance of a Warrant certificate or book-entry position for a fraction of a Warrant.

5.4 Service Charges. No service charge shall be made for any exchange or registration of transfer of Warrants.

5.5 Warrant Execution and Countersignature. The Warrant Agent is hereby authorized to countersign and to deliver, in accordance with the terms of this Agreement, the Warrants required to be issued pursuant to the provisions of this Section 5, and the Company, whenever required by the Warrant Agent, shall supply the Warrant Agent with Warrants duly executed on behalf of the Company for such purpose.

5.6 [Reserved].

6. Redemption.

6.1 Redemption For Cash. All, but not less than all, of the outstanding Warrants may be redeemed for cash, at the option of the Company, at any time during the Exercise Period, at the office of the Warrant Agent, upon notice to the Registered Holders of the Warrants, as described in Section 6.2 hereof, at a Redemption Price of $0.01 per Warrant, provided that the last reported sale price of the Common Shares has been at least $18.00 per share (subject to adjustment in compliance with Section 4 hereof), on each of twenty (20) trading days within the thirty (30) trading day period ending on the third (3rd) trading day prior to the date on which notice of the redemption is given and provided that there is an effective registration statement covering the Common Shares issuable upon exercise of the Warrants, and a current prospectus relating thereto, available throughout the 30-day Redemption Period (as defined in Section 6.2 hereof) or the Company has elected to require the exercise of the Warrants on a “cashless basis” pursuant to subsection 3.3.1(b) hereof and such cashless exercise is exempt from registration under the Securities Act; provided, however, that if and when the Warrants become redeemable by the Company, the Company may not exercise such redemption right if the issuance of Common Shares upon exercise of the Warrants is not exempt from registration or qualification under applicable state blue sky laws or the Company is unable to effect such registration or qualification.

6.2 Date Fixed for, and Notice of, Redemption; Redemption Price. In the event that the Company elects to redeem the Warrants pursuant to Section 6.1 hereof, the Company shall fix a date for the redemption (the “Redemption Date”). Notice of redemption shall be mailed by first class mail, postage prepaid, by the Company not less than thirty (30) days prior to the Redemption Date (the “30-day Redemption Period”) to the Registered Holders of the Warrants to be redeemed at their last addresses as they shall appear on the registration books. Any notice mailed in the manner herein provided shall be conclusively presumed to have been duly given whether or not the Registered Holder received such notice. As used in this Agreement, “Redemption Price” shall mean the price per Warrant at which any Warrants are redeemed pursuant to Section 6.1.

6.3 Exercise After Notice of Redemption. The Warrants may be exercised for cash (or on a “cashless basis” pursuant to Section 3.3.1 hereof, if applicable) at any time after notice of redemption shall have been given by the Company pursuant to Section 6.2 hereof and prior to the Redemption Date. In the event that the Company determines to require all holders of Warrants to exercise their Warrants on a “cashless basis” pursuant to Section 3.3.1 hereof, the notice of redemption shall contain instructions on how to calculate the number of Common Shares to be received upon exercise of the Warrants, including the “Fair Market Value” (as such term is defined in subsection 3.3.1(b) hereof) in such case. On and after the Redemption Date, the record holder of the Warrants shall have no further rights except to receive, upon surrender of the Warrants, the Redemption Price.

7. Other Provisions Relating to Rights of Holders of Warrants.

7.1 No Rights as Shareholder. A Warrant does not entitle the Registered Holder thereof to any of the rights of a shareholder of the Company, including, without limitation, the right to receive dividends, or other distributions, exercise any preemptive rights, to vote or to consent or to receive notice as shareholders in respect of the general meetings of the Company or the appointment of directors of the Company or any other matter.

7.2 Lost, Stolen, Mutilated or Destroyed Warrants. If any Warrant is lost, stolen, mutilated or destroyed, the Company and the Warrant Agent may on such terms as to indemnity or otherwise as they may in their discretion impose (which shall, in the case of a mutilated Warrant, include the surrender thereof), issue a new Warrant of like denomination, tenor and date as the Warrant so lost, stolen, mutilated or destroyed. Any such new Warrant shall constitute a substitute contractual obligation of the Company, whether or not the allegedly lost, stolen, mutilated or destroyed Warrant shall be at any time enforceable by anyone.

7.3 Reservation of Common Shares. The Company shall at all times reserve and keep available a number of its authorized but unissued Common Shares that shall be sufficient to permit the exercise in full of all outstanding Warrants issued pursuant to this Agreement.

7.4 Registration of Common Shares; Cashless Exercise at Company’s Option.

7.4.1 Registration of the Common Shares. The Company agrees that as soon as practicable, but in no event later than fifteen (15) Business Days after the date of this Agreement, it shall use its commercially reasonable efforts to file with the Commission a registration statement for the registration, under the Securities Act, of the Common Shares issuable upon exercise of the Warrants. The Company shall use its commercially reasonable efforts to cause the same to become effective and to maintain the effectiveness of such registration statement, and a current prospectus relating thereto, until the expiration of the Warrants in accordance with the provisions of this Agreement. If any such registration statement has not been declared effective by the 90th day following the date of this Agreement, holders of the Warrants shall have the right, during the period beginning on the 91st day after the date of this Agreement and ending upon such registration statement being declared effective by the Commission, and during any other period when the Company shall fail to have maintained an effective registration statement covering the Common Shares issuable upon exercise of the Warrants, to exercise such Warrants on a “cashless basis,” by exchanging the Warrants (in accordance with Section 3(a)(9) of the Securities Act (or any successor rule) or another exemption) for that number of Common Shares equal to the quotient obtained by dividing (x) the product of the number of Common Shares underlying the Warrants, multiplied by the difference between the Exercise Price and the Fair Market Value (as defined below) by (y) the Fair Market Value. Solely for purposes of this subsection 7.4.1, “Fair Market Value” shall mean the volume weighted average price of the Common Shares as reported during the five (5) trading day period ending on the trading day prior to the date that notice of exercise is received by the Warrant Agent from the holder of such Warrants or its securities broker or intermediary. The date that notice of cashless exercise is received by the Warrant Agent shall be conclusively determined by the Warrant Agent. In connection with the “cashless exercise” of a Public Warrant, the Company shall, upon request, provide the Warrant Agent with an opinion of counsel for the Company (which shall be an outside law firm with securities law experience) stating that (i) the exercise of the Warrants on a cashless basis in accordance with this subsection 7.4.1 is not required to be registered under the Securities Act and (ii) the Common Shares issued upon such exercise shall be freely tradable under United States federal securities laws by anyone who is not an affiliate (as such term is defined in Rule 144 under the Securities Act (or any successor rule)) of the Company and, accordingly, shall not be required to bear a restrictive legend. Except as provided in subsection 7.4.2, for the avoidance of any doubt, unless and until all of the Warrants have been exercised, the Company shall continue to be obligated to comply with its registration obligations under the first three sentences of this subsection 7.4.1.

7.4.2 Cashless Exercise at Company’s Option. If the Common Shares are at the time of any exercise of a Warrant not listed on a national securities exchange such that the Common Shares satisfy the definition of a “covered security” under Section 18(b)(1) of the Securities Act (or any successor statute), the Company may, at its option, (i) require holders of Warrants who exercise Warrants to exercise such Warrants on a “cashless basis” in accordance with Section 3(a)(9) of the Securities Act (or any successor statute) and (ii) in the event the Company so elects, the Company shall (x) not be required to file or maintain in effect a registration statement for the registration, under the Securities Act, of the Common Shares issuable upon exercise of the Warrants, notwithstanding anything in this Agreement to the contrary and (y) use its commercially reasonable efforts to register or qualify the Common Shares issuable upon exercise of the Warrant under the blue sky laws of the state of residence of the exercising Warrant holder to the extent an exemption is not available. To exercise the Warrants on a cashless basis pursuant to this Section 7.4.2, each Registered Holder would pay the Warrant Price by surrendering the Warrants in exchange for a number of Common Shares equal to the quotient obtained by dividing (i) the product of (A) the number of the Common Shares underlying the Warrants and (B) the excess of the “Fair Market Value” (as defined in this Section 7.4.2) over the Warrant Price of the Warrants by (ii) the Fair Market Value. Solely for purposes of this Section 7.4.2, the “Fair Market Value,” shall mean 10-Day Average Closing Price as of the date on which the notice of exercise is received by the Warrant Agent.

8. Concerning the Warrant Agent and Other Matters.

8.1 Payment of Taxes. The Company shall from time to time promptly pay all taxes and charges that may be imposed upon the Company or the Warrant Agent in respect of the issuance or delivery of Common Shares upon the exercise of the Warrants, but the Company shall not be obligated to pay any transfer taxes in respect of the Warrants or such Common Shares.

8.2 Resignation, Consolidation, or Merger of Warrant Agent.

8.2.1 Appointment of Successor Warrant Agent. The Warrant Agent, or any successor to it hereafter appointed, may resign its duties and be discharged from all further duties and liabilities hereunder after giving sixty (60) days’ notice in writing to the Company. If the office of the Warrant Agent becomes vacant by resignation or incapacity to act or otherwise, the Company shall appoint in writing a successor Warrant Agent in place of the Warrant Agent. If the Company shall fail to make such appointment within a period of thirty (30) days after it has been notified in writing of such resignation or incapacity by the Warrant Agent or by the holder of a Warrant (who shall, with such notice, submit his, her or its Warrant for inspection by the Company), then the holder of any Warrant may apply to the Supreme Court of the State of New York for the County of New York for the appointment of a successor Warrant Agent at the Company’s cost. Any successor Warrant Agent, whether appointed by the Company or by such court, shall be a corporation or other entity organized and existing under the laws of the State of New York, in good standing and having its principal office in the Borough of Manhattan, City and State of New York, and authorized under such laws to exercise corporate trust powers and subject to supervision or examination by federal or state authority. After appointment, any successor Warrant Agent shall be vested with all the authority, powers, rights, immunities, duties and obligations of its predecessor Warrant Agent with like effect as if originally named as Warrant Agent hereunder, without any further act or deed; but if for any reason it becomes necessary or appropriate, the predecessor Warrant Agent shall execute and deliver, at the expense of the Company, an instrument transferring to such successor Warrant Agent all the authority, powers and rights of such predecessor Warrant Agent hereunder; and upon request of any successor Warrant Agent, the Company shall make, execute, acknowledge and deliver any and all instruments in writing for more fully and effectually vesting in and confirming to such successor Warrant Agent all such authority, powers, rights, immunities, duties and obligations.

8.2.2 Notice of Successor Warrant Agent. In the event a successor Warrant Agent shall be appointed, the Company shall give notice thereof to the predecessor Warrant Agent and the Transfer Agent for the Common Shares not later than the effective date of any such appointment.

8.2.3 Merger or Consolidation of Warrant Agent. Any entity into which the Warrant Agent may be merged or with which it may be consolidated or any entity resulting from any merger or consolidation to which the Warrant Agent shall be a party shall be the successor Warrant Agent under this Agreement without any further act.

8.3 Fees and Expenses of Warrant Agent.

8.3.1 Remuneration. The Company agrees to pay the Warrant Agent reasonable remuneration for its services as such Warrant Agent hereunder and shall, pursuant to its obligations under this Agreement, reimburse the Warrant Agent upon demand for all expenditures that the Warrant Agent may reasonably incur in the execution of its duties hereunder.

8.3.2 Further Assurances. The Company agrees to perform, execute, acknowledge and deliver or cause to be performed, executed, acknowledged and delivered all such further and other acts, instruments and assurances as may reasonably be required by the Warrant Agent for the carrying out or performing of the provisions of this Agreement.

8.4 Liability of Warrant Agent.

8.4.1 Reliance on Company Statement. Whenever in the performance of its duties under this Agreement, the Warrant Agent shall deem it necessary or desirable that any fact or matter be proved or established by the Company prior to taking or suffering any action hereunder, such fact or matter (unless other evidence in respect thereof be herein specifically prescribed) may be deemed to be conclusively proved and established by a statement signed by a Chief Executive Officer, Chief Financial Officer, Secretary or Chairman of the Board of the Company and delivered to the Warrant Agent. The Warrant Agent may rely upon such statement for any action taken or suffered in good faith by it pursuant to the provisions of this Agreement.

8.4.2 Indemnity. The Warrant Agent shall be liable hereunder only for its own, or its representatives’, gross negligence, willful misconduct, fraud, bad faith or material breach of this Agreement. The Company agrees to indemnify the Warrant Agent and save it harmless against any and all liabilities, including judgments, out-of-pocket costs and reasonable counsel fees, for anything done or omitted by the Warrant Agent in the execution of this Agreement, except as a result of the Warrant Agent’s or its representatives’ gross negligence, willful misconduct, fraud, bad faith or material breach of this Agreement.

8.4.3 Exclusions. The Warrant Agent shall have no responsibility with respect to the validity of this Agreement or with respect to the validity or execution of any Warrant (except its countersignature thereof). The Warrant Agent shall not be responsible for any breach by the Company of any covenant or condition contained in this Agreement or in any Warrant. The Warrant Agent shall not be responsible to make any adjustments required under the provisions of Section 4 hereof or responsible for the manner, method or amount of any such adjustment or the ascertaining of the existence of facts that would require any such adjustment; nor shall it by any act hereunder be deemed to make any representation or warranty as to the authorization or reservation of any Common Shares to be issued pursuant to this Agreement or any Warrant or as to whether any Common Shares shall, when issued, be valid and fully paid and non-assessable.

8.5 Acceptance of Agency. The Warrant Agent ▇▇▇▇▇▇ accepts the agency established by this Agreement and agrees to perform the same upon the terms and conditions herein set forth and among other things, shall account promptly to the Company with respect to Warrants exercised and concurrently account for, and pay to the Company, all monies received by the Warrant Agent for the purchase of Common Shares through the exercise of the Warrants.

8.6 [Reserved].

9. Miscellaneous Provisions.

9.1 Successors. All the covenants and provisions of this Agreement by or for the benefit of the Company or the Warrant Agent shall bind and inure to the benefit of their respective successors and assigns.

9.2 Notices.

9.3 Applicable Law. The validity, interpretation, and performance of this Agreement and of the Warrants shall be governed in all respects by the laws of the State of New York, without giving effect to conflicts of law principles that would result in the application of the substantive laws of another jurisdiction.

The Company hereby waives any objection to such exclusive jurisdiction and that such courts represent an inconvenient forum.

9.4 Persons Having Rights under this Agreement. Nothing in this Agreement shall be construed to confer upon, or give to, any person, corporation or other entity other than the parties hereto and the Registered Holders of the Warrants any right, remedy or claim under or by reason of this Agreement or of any covenant, condition, stipulation, promise or agreement hereof.

9.6 Counterparts. This Agreement may be executed in any number of original or facsimile counterparts and each of such counterparts shall for all purposes be deemed to be an original, and all such counterparts shall together constitute but one and the same instrument.

9.7 Effect of Headings. The section headings herein are for convenience only and are not part of this Agreement and shall not affect the interpretation thereof.

9.8 Amendments.

Notwithstanding the foregoing, the Company may lower the Warrant Price or extend the duration of the Exercise Period pursuant to Sections 3.1 and 3.2 hereof, respectively, without the consent of the Registered Holders.

9.9 Severability. This Agreement shall be deemed severable, and the invalidity or unenforceability of any term or provision hereof shall not affect the validity or enforceability of this Agreement or of any other term or provision hereof.

Warrant Certificate

This Warrant Certificate certifies that, or registered assigns, is the registered holder of warrant(s) evidenced hereby (the “Warrants” and each, a “Warrant”) to purchase Common Shares (“Common Shares”) of NorthStar Earth & Space Enterprises, Inc., a corporation existing under the Canada Business Corporations Act (the “Company”). Each Warrant entitles the holder, upon exercise during the period set forth in the Warrant Agreement referred to below, to receive from the Company that number of fully paid and non-assessable Common Shares as set forth below, at the exercise price (the “Exercise Price”) as determined pursuant to the Warrant Agreement, payable in lawful money of the United States of America (or through “cashless exercise” as provided for in the Warrant Agreement) upon surrender of this Warrant Certificate and payment of the Exercise Price at the office or agency of the Warrant Agent referred to below, subject to the conditions set forth herein and in the Warrant Agreement. Defined terms used in this Warrant Certificate but not defined herein shall have the meanings given to them in the Warrant Agreement.

Each whole Warrant is initially exercisable for one fully paid and non-assessable Common Share. Fractional Common Shares shall not be issued upon exercise of any Warrant. If, upon the exercise of Warrants, a holder would be entitled to receive a fractional interest in a Common Share, the Company shall, upon exercise, round down to the nearest whole number of Common Shares to be issued to the warrant holder. The number of Common Shares issuable upon exercise of the Warrants is subject to adjustment upon the occurrence of certain events as set forth in the Warrant Agreement.

The initial Exercise Price is equal to $11.50 per share. The Exercise Price is subject to adjustment upon the occurrence of certain events as set forth in the Warrant Agreement.

Subject to the conditions set forth in the Warrant Agreement, the Warrants may be exercised only during the Exercise Period and to the extent not exercised by the end of such Exercise Period, such Warrants shall become void. The Warrants may be redeemed, subject to certain conditions, as set forth in the Warrant Agreement.

Reference is hereby made to the further provisions of this Warrant Certificate set forth on the reverse hereof and such further provisions shall for all purposes have the same effect as though fully set forth at this place.

This Warrant Certificate shall not be valid unless countersigned by the Warrant Agent, as such term is used in the Warrant Agreement.

This Warrant Certificate shall be governed by and construed in accordance with the internal laws of the State of New York, without regard to conflicts of laws principles thereof.

[Form of Warrant Certificate]

[Reverse]

The Warrants evidenced by this Warrant Certificate are part of a duly authorized issue of Warrants entitling the holder on exercise to receive Common Shares and are issued or to be issued pursuant to an Amended and Restated Public Warrant Agreement dated as of October 1, 2026 (the “Warrant Agreement”), duly executed and delivered by the Company to Continental Stock Transfer & Trust Company, a New York corporation, as warrant agent (the “Warrant Agent”), which Warrant Agreement is hereby incorporated by reference in and made a part of this instrument and is hereby referred to for a description of the rights, limitation of rights, obligations, duties and immunities thereunder of the Warrant Agent, the Company and the holders (the words “holders” or “holder” meaning the Registered Holders or Registered Holder, respectively) of the Warrants. A copy of the Warrant Agreement may be obtained by the holder hereof upon written request to the Company. Defined terms used in this Warrant Certificate but not defined herein shall have the meanings given to them in the Warrant Agreement.

Warrants may be exercised at any time during the Exercise Period set forth in the Warrant Agreement. The holder of Warrants evidenced by this Warrant Certificate may exercise them by surrendering this Warrant Certificate, with the form of election to purchase set forth hereon properly completed and executed, together with payment of the Exercise Price as specified in the Warrant Agreement (or through “cashless exercise” as provided for in the Warrant Agreement) at the principal corporate trust office of the Warrant Agent. In the event that upon any exercise of Warrants evidenced hereby the number of Warrants exercised shall be less than the total number of Warrants evidenced hereby, there shall be issued to the holder hereof or his, her or its assignee, a new Warrant Certificate evidencing the number of Warrants not exercised.

Notwithstanding anything else in this Warrant Certificate or the Warrant Agreement, no Warrant may be exercised unless at the time of exercise (i) a registration statement covering the Common Shares to be issued upon exercise is effective under the Securities Act and (ii) a prospectus thereunder relating to the Common Shares is current, except through “cashless exercise” as provided for in the Warrant Agreement.

The Warrant Agreement provides that upon the occurrence of certain events the number of Common Shares issuable upon exercise of the Warrants and the Exercise Price set forth on the face hereof may, subject to certain conditions, be adjusted. If, upon exercise of a Warrant, the holder thereof would be entitled to receive a fractional interest in a Common Share, the Company shall, upon exercise, round down to the nearest whole number of Common Shares to be issued to the holder of the Warrant.

Warrant Certificates, when surrendered at the principal corporate trust office of the Warrant Agent by the Registered Holder thereof in person or by legal representative or attorney duly authorized in writing, may be exchanged, in the manner and subject to the limitations provided in the Warrant Agreement, but without payment of any service charge, for another Warrant Certificate or Warrant Certificates of like tenor evidencing in the aggregate a like number of Warrants.

Upon due presentation for registration of transfer of this Warrant Certificate at the office of the Warrant Agent a new Warrant Certificate or Warrant Certificates of like tenor and evidencing in the aggregate a like number of Warrants shall be issued to the transferee(s) in exchange for this Warrant Certificate, subject to the limitations provided in the Warrant Agreement, without charge except for any tax or other governmental charge imposed in connection therewith.

The Company and the Warrant Agent may deem and treat the Registered Holder(s) hereof as the absolute owner(s) of this Warrant Certificate (notwithstanding any notation of ownership or other writing hereon made by anyone), for the purpose of any exercise hereof, of any distribution to the holder(s) hereof, and for all other purposes, and neither the Company nor the Warrant Agent shall be affected by any notice to the contrary. Neither the Warrants nor this Warrant Certificate entitles any holder hereof to any rights of a shareholder of the Company.
