C.       The board of directors of GX (the “GX Board”) has (a) determined that this Agreement and the Transactions are fair to, and in the best interests of, GX and its shareholders (the “GX Shareholders”), (b) approved this Agreement and the Transactions and declared their advisability, and (c) recommended that the GX Shareholders approve and adopt this Agreement and approve the Transactions and directed that this Agreement and the Transactions be submitted for consideration by the GX Shareholders at the GX Shareholder Meeting.

E.       The board of directors of Merger Sub (the “Merger Sub Board”) has (a) determined that this Agreement and the Transactions are fair to, and in the best interests of, Merger Sub and the Company as its sole shareholder and (b) recommended that the Company approve and adopt this Agreement and approve the Transactions.

F.       The board of directors of ECRC (the “ECRC Board”) has (a) determined that the Transactions are fair to, and in the best interests of, ECRC and Intermediate Holdco as its sole shareholder and (b) recommended that Intermediate Holdco approve the Transactions.

J.       Concurrently with the execution of this Agreement, GX, the Company and certain Company Pre-Closing Shareholders are entering into a support agreement (the “Company Support Agreement”), pursuant to which certain Company Pre-Closing Shareholders are agreeing, among other things, to vote in favor of each of the Company Resolutions.

K.       In connection with the Transactions, GX is obligated under the terms of its Amended and Restated Certificate of Incorporation (the “GX Charter”) to provide the GX Public Shareholders the option to have their Class A Shares redeemed, for the consideration and on the terms and subject to the conditions and limitations set forth in the GX Charter (the “Redemption Right”).

ARTICLE II 
MERGER CONSIDERATION

2.1              Effect on Capital Stock.

(a)                At the First Merger Effective Time, by virtue of the First Merger and without any further action:

(i)                 Each issued and outstanding Founder Share (excluding, for the avoidance of doubt, any Forfeited Shares) will be converted into one Class B common share of the First Merger Surviving Company (each, a “First Merger Class B Share”).

(ii)               Each issued and outstanding Class A Share that is not a Redemption Share will be converted into one Class A common share of the First Merger Surviving Company, each of which will be, by its terms, exchangeable for a number of new Company Common Shares equal to the Exchange Ratio in accordance with this Agreement at the Company’s sole option and without further action by any holder thereof (each, a “First Merger Class A Share”).

(iii)             Each issued and outstanding share of capital stock of GX then held by GX (including shares held in treasury) will be canceled and retired and cease to exist, and no consideration will be delivered in exchange therefor.

(iv)             All of the issued and outstanding shares of capital stock of Merger Sub (other than those shares addressed by Section 2.1(a)(v) below) will be converted into one First Merger Class A Share.

(v)               Each issued and outstanding share of capital stock of Merger Sub then held by Merger Sub (including shares held in treasury) will be canceled and retired and cease to exist, and no consideration will be delivered in exchange therefor.

(b)               At the Exchange Time:

(i)                 the Company will exercise its unilateral option to purchase each First Merger Class A Share not held by the Company from the holder thereof in exchange for a number of new Company Common Shares equal to the Exchange Ratio, with no further action required on the part of any Person, such that each holder who submits a Letter of Transmittal will do so with respect to the applicable number of Company Common Shares and not the applicable number of First Merger Class A Shares; and

(ii)               in connection with the First Merger, the Company shall assume the GX Warrant Agreement and enter into such amendments thereto as are necessary to give effect to the provisions of this Section 2.1(b)(ii), and each GX Warrant that is issued and outstanding immediately prior to the Exchange Time will automatically, and without any action on the part of its holder, be converted into one Former GX Company Warrant pursuant to and in accordance with the GX Warrant Agreement. Each Former GX Company Warrant shall be subject to the same terms and conditions (including exercisability terms) as were applicable to the corresponding GX Warrant immediately

prior to the Exchange Time, except to the extent such terms or conditions are rendered inoperative by the Transactions. Accordingly, effective as of the Exchange Time: (A) each Former GX Company Warrant shall be exercisable solely for Company Common Shares; (B) the number of Company Common Shares subject to each Former GX Company Warrant shall be equal to (x) the number of shares of GX Common Stock subject to the applicable GX Warrant multiplied by (y) the Exchange Ratio; and (C) the per share exercise price for the Company Common Shares issuable upon exercise of such GX Former Company Warrant shall be equal to (x) the per share exercise price for the GX Common Shares subject to the applicable GX Warrant, as in effect immediately prior to the Exchange Time, divided by (y) the Exchange Ratio, rounding the resulting exercise price down to the nearest whole cent; and (D) if the aggregate number of Company Common Shares that a holder of any Former GX Company Warrants would be entitled to receive upon any exercise of any Former GX Company Warrants would otherwise include a fraction of a Company Common Share, the Company shall, upon such exercise, round down to the nearest whole number the aggregate number of Company Common Shares to be issued to such holder as a result of the exercise of all such Former GX Company Warrants so exercised. In the event that the Class A Shares and the GX Public Warrants comprising a single GX Public Unit have not been detached so as to permit separate transferability or trading thereof prior to the First Merger Effective Time, then effective immediately prior to the First Merger Effective Time, any and all GX Public Units shall be automatically detached and broken out into their constituent parts, such that a holder of one GX Public Unit shall thereupon hold one Class A Share and one-third of one GX Public Warrant, and such underlying constituent securities shall be converted in accordance with Sections 2.1(a) and 2.1(b)(ii), respectively; provided, however, that if upon such detachment, a holder of GX Public Warrants would be deemed to hold a fractional GX Public Warrant, then prior to such conversion the number of GX Public Warrants deemed to be held by such holder shall be rounded down to the nearest whole number.

(c)                Immediately following the Exchange Time, the Contribution will occur.

(d)               Immediately following the Contribution Time, the Second Merger will occur. At the Second Merger Effective Time, by virtue of the Second Merger and without any further action:

(i)                 Each issued and outstanding First Merger Class A Share (which, for the avoidance of doubt, will be held only by Intermediate Holdco at such time) (other than those shares addressed by Section 2.1(d)(iii) below) will be converted into a number of Class A common shares of the Second Merger Surviving Company, newly issued by the Second Merger Surviving Company, equal to the Exchange Ratio (each, a “Second Merger Class A Share”).

(ii)               Each issued and outstanding First Merger Class B Share will be converted into a number of Class B common shares of the Second Merger Surviving Company, newly issued by the Second Merger Surviving Company, equal to the Exchange Ratio (each, a “Second Merger Class B Share”), which will be exchangeable into Company Common Shares only upon the terms and subject to the conditions specified in the Exchange Agreement.

(iii)             Each issued and outstanding First Merger Class A Share then held by First Merger Surviving Company (including shares held in treasury) will be canceled and retired and cease to exist, and no consideration will be delivered in exchange therefor.

(iv)             Each issued and outstanding share of capital stock of ECRC (other than those shares addressed by Section 2.1(d)(v) below) will be converted into a number of Second Merger Class A Shares, newly issued by the Second Merger Surviving Company, equal to the Second Merger Class A Ratio.

(v)               Each issued and outstanding share of capital stock of ECRC then held by ECRC (including shares held in treasury) will be canceled and retired and cease to exist, and no consideration will be delivered in exchange therefor.

2.2              Company Options, Company Warrants and Certain Indebtedness.

(a)                Company Options. All Company Options outstanding at the Closing shall remain outstanding immediately following the Closing pursuant to their terms, the Company Board shall take such action as required under the Company Incentive Plans in connection with the Reverse Stock Split and, if the Company Board shall determine that an equitable adjustment should be made pursuant to the Company Options in respect of the Reverse Stock Split (including the requirements under Section 5.1 of each Company Incentive Plan), then the Company Options shall be equitably adjusted as determined by the Company Board in accordance with the terms of Section 5.1 of each of the Company Incentive Plans, without any action required on the part of the holder thereof; provided that the Company’s Board shall consult with GX in connection with making any equitable adjustments to the Company Options in accordance with this Section 2.2(a).

(b)               Company Warrants. The Company Warrants will remain outstanding in connection with the Transactions. The Company will provide holders of the Company Warrants with notice required in connection with the Reverse Stock Split, if any, and such Company Warrants will be adjusted as required pursuant to their terms in connection therewith, if so required.

(c)                Company Convertible Note. The Company will use reasonable best efforts to cause the convertible security agreement set forth on Annex 2.2(c) (the “Convertible Security Funding Agreement”) to remain outstanding in connection with the Transactions (unless GX and the Company mutually agree to enter into an agreement as a result of which the Convertible Security Funding Agreement must be paid off in full and terminated in accordance with its terms), and to obtain any required consent under the Convertible Security Funding Agreement in connection therewith.

(d)               CEO Loan Agreement. The Smith Credit Agreement and the Smith GSA (each, as defined in the Company Support Agreement) will remain outstanding in connection with the Transactions.

2.3              Issuance of Merger Consideration.

(a)                No Issuance of Fractional Shares. No fractional Company Common Shares will be issued pursuant to the Transactions, and instead any such fractional share that would otherwise be issued will be rounded down to the nearest whole share.

(b)               Exchange Fund. The Exchange Agent will be appointed as exchange agent. At the Closing, the Company will deposit, or will cause to be deposited, in book-entry form, with the Exchange Agent for the benefit of the GX Shareholders, for exchange in accordance with this Agreement, the number of Company Common Shares issuable pursuant to Section 2.1(b)(i) (the “Transaction Consideration Shares” and such deposited Transaction Consideration Shares, the “Exchange Fund”). The Company will cause the Exchange Agent to issue the Transaction Consideration Shares out of the Exchange Fund to the GX Shareholders in accordance with this Agreement. The Exchange Fund will not be used for any other purpose other than as contemplated by this Agreement.

(c)                Exchange Procedures. As soon as practicable following the First Merger Effective Time, and in any event within two Business Days following the First Merger Effective Time, the Company will cause the Exchange Agent to deliver to each GX Shareholder, as of immediately prior to the First Merger Effective Time, represented by certificate or book entry, a letter of transmittal and instructions (in customary form reasonably agreed to by the Company and GX prior to the First Merger Effective Time) for use in exchanging such GX Shareholder’s Class A Shares for such GX Shareholder’s applicable portion of the Transaction Consideration Shares from the Exchange Fund (a “Letter of Transmittal”), and promptly following receipt of a GX Shareholder’s properly executed Letter of Transmittal, deliver such GX Shareholder’s applicable portion of the Transaction Consideration Shares to such GX Shareholder. The Company shall use its reasonable best efforts to cause the Exchange Agent to deliver each GX Shareholder’s applicable portion of the Transaction Consideration Shares to such GX Shareholder within two Business Days following receipt of the applicable Letter of Transmittal.

(d)               Termination of Exchange Fund. Any portion of the Exchange Fund that remains undistributed to the GX Shareholders one year after the First Merger Effective Time will be delivered to the Company, upon demand, and any GX Shareholders who have not complied with this Section 2.3 will thereafter look only to the Company for their Transaction Consideration Shares. Any portion of the Exchange Fund remaining unclaimed by the GX Shareholders as of a date which is immediately prior to such time as such amounts would otherwise escheat to or become property of any Governmental Entity will, to the extent permitted by applicable Law, become the property of the Company free and clear of any claims or interest of any person previously entitled thereto.

2.4              Other Adjustments. If at any time during the period between the date of this Agreement and the First Merger Effective Time, any change in the capitalization of the Company or GX occurs as a result of any reclassification, recapitalization, split (including a reverse split or consolidation) or combination, exchange or readjustment of interests, or any dividend or distribution is declared with a record date during such period, then the Transaction Consideration Shares will be equitably adjusted to reflect such change.

2.5              Tax Treatment. The Transactions are intended to be treated as follows for U.S. federal (and applicable state and local) income Tax purposes: (a) the First Merger and the transactions described in Section 2.1(a)-(b) in connection with the First Merger are intended to be treated as a taxable exchange of the Class A Shares for Company Common Shares by the shareholders of GX and a taxable exchange of the GX Warrants for Former GX Company Warrants by the warrant holders of GX, in each case, that is governed by section 1001 of the Code, (b) the

Second Merger is intended to be treated as a reorganization described in section 368(a) of the Code that is not subject to gain or income recognition or withholding under section 897 or section 1445 of the Code and (c) the Transactions, collectively, are intended to result in no Party or Affiliate thereof satisfying the requirements of section 7874(a)(2)(B)(ii) of the Code or otherwise being treated as an “expatriated entity” or “surrogate foreign corporation” under section 7874 of the Code and the Treasury Regulations thereunder (collectively, subject to any changes agreed to pursuant to Section 5.9(d), the “Intended Tax Treatment”). This Agreement is intended to constitute, and the Parties hereby adopt this Agreement as, a “plan of reorganization” within the meaning of Treasury Regulations sections 1.368-2(g) and 1.368-3(a) with respect to the Second Merger. The Parties shall report the Transactions in all cases in accordance with the Intended Tax Treatment except, and then solely to the extent, otherwise required by a final determination under applicable Law. Each Party shall use reasonable best efforts to notify the others regarding any challenge to the Intended Tax Treatment by any Governmental Entity.

2.6              Withholding. Notwithstanding any provision contained herein to the contrary, the Parties, and their respective Affiliates and Representatives, shall be entitled to deduct and withhold from the amounts otherwise payable to any Person pursuant to this Agreement such amounts as are required to be deducted and withheld under any applicable Law. Any amounts so deducted or withheld will be treated for all purposes of this Agreement as having been paid to such Person.

The Company has made available to GX true, complete and correct copies of the organizational

documents of the Company and the Company Subsidiaries, each as amended through the date of this Agreement, and each such document as so made available is in full force and effect on the date of this Agreement and none of the Company or the Company Subsidiaries is in material violation of their respective organizational documents.

Trading in GX Public Units, Class A Shares, and GX Public Warrants on NASDAQ is not currently halted or suspended. No delisting, suspension of trading or cease trading order with respect to any securities of GX is pending or, to the Knowledge of GX, threatened. No Action (whether formal or informal) against GX by any securities commission, stock exchange (including NASDAQ) or similar regulatory authority under applicable securities Laws or the rules and regulations of NASDAQ is in effect or ongoing. GX has not taken any action in an attempt to terminate the registration of the GX Public Units, the Class A Shares or the GX Public Warrants under the Exchange Act.

(b)               GX has filed all forms, reports, schedules, statements, registration statements, prospectuses and other documents required to be filed or furnished by GX with the SEC under the Securities Act or the Exchange Act, together with any amendments, restatements or supplements thereto, and will file all such forms, reports, schedules, statements and other documents required to be filed subsequent to the date of this Agreement and prior to the Closing. The disclosures filed with the SEC were prepared in all material respects in accordance with the requirements of the Securities Act and the Exchange Act, as the case may be. As used in this Section 4.4(b) the term “file” will be broadly construed to include any manner permitted by SEC rules and regulations in which a document or information is furnished, supplied or otherwise made available to the SEC. The documents and information comprising the GX Public Disclosure Record, as at the respective dates they were filed, were in compliance in all material respects with applicable securities Laws and, where applicable, the rules and policies of NASDAQ and did not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading.

(c)                As of the date of this Agreement, there are no outstanding or unresolved comments in comment letters from any securities commission or similar regulatory authority with respect to any of the GX Public Disclosure Record (other than such comment letters a copy of which has been provided to the Company prior to the date hereof) and neither GX nor any of the GX Public Disclosure Record is, to the Knowledge of GX, subject of an ongoing audit, review, comment or investigation by any securities commission or similar regulatory authority.

(e)                The financial statements (including, in each case, any notes thereto) of GX contained or incorporated by reference in the GX Public Disclosure Record (the “GX Financial Statements”) fairly present in all material respects the financial position, results of operations, changes in shareholders’ equity and cash flows of GX at the respective dates of and for the periods referred to in such financial statements, all prepared in accordance with (i) GAAP consistently applied and (ii) applicable requirements of the Securities Act, the Exchange Act and the Sarbanes-Oxley Act, as the case may be, and the rules and regulations of the SEC promulgated thereunder applicable to the GX Financial Statements.

(f)                Except as and to the extent reflected or reserved against in the GX Financial Statements, GX has not incurred any liabilities or obligations of the type required to be reflected on a balance sheet in accordance with GAAP that are not adequately reflected or reserved on or provided for in GX Financial Statements, other than liabilities or obligations of the type required to be reflected on a balance sheet in accordance with GAAP that have been incurred since the date of GX’s incorporation in the ordinary course of business.

(g)               GX has established and maintains disclosure controls and procedures (as defined in Rule 13a-15 under the Exchange Act). Such disclosure controls and procedures are designed to ensure that material information relating to GX and other material information required to be disclosed by GX in the reports and other documents that it files or furnishes under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC, and that all such material information is accumulated and communicated to

GX’s principal executive officer and its principal financial officer as appropriate to allow timely decisions regarding required disclosure and to make the certifications required pursuant to Sections 302 and 906 of the Sarbanes-Oxley Act. Such disclosure controls and procedures are effective in timely alerting GX’s principal executive officer and principal financial officer to material information required to be included in GX’s periodic reports required under the Exchange Act.

(h)               GX maintains systems of internal control over financial reporting that are sufficient to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with GAAP, including policies and procedures sufficient to provide reasonable assurance: (i) that GX maintains records that in reasonable detail accurately and fairly reflect, in all material respects, its transactions and dispositions of assets; (ii) that transactions are recorded as necessary to permit the preparation of financial statements in conformity with GAAP; (iii) that receipts and expenditures are being made only in accordance with authorizations of management and its board of directors; and (iv) regarding prevention or timely detection of unauthorized acquisition, use or disposition of its assets that could have a material effect on its financial statements. GX has delivered to the Company a true and complete copy of any disclosure (or, if unwritten, a summary thereof) by any representative of the Company to the Company’s independent auditors relating to any material weaknesses in internal controls and any significant deficiencies in the design or operation of internal controls that would adversely affect the ability of the Company to record, process, summarize and report financial data. GX has no knowledge of any fraud or whistle-blower allegations, whether or not material, that involve management or other employees or consultants who have or had a significant role in the internal control over financial reporting of GX. Since December 31, 2021, there have been no material changes in the GX’s internal control over financial reporting.

4.5              Information Supplied. None of the information relating to GX or its Affiliates supplied or to be supplied by GX for inclusion or incorporation by reference in (i) the Form S-4 will, at the time the Form S-4 is filed with the SEC, at any time it is amended or supplemented and at the time it becomes effective under the Securities Act, contain any untrue statement of a material fact or omit to state any 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 are made, not misleading, or (ii) the Joint Proxy Statement will, at the date the Joint Proxy Statement is first mailed to the Company Pre-Closing Shareholders and the GX Shareholders and at the time of the Company Shareholder Meeting and the GX Shareholder Meeting, contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they are made, not misleading. The portions of the Form S-4 and the Joint Proxy Statement relating to GX and its Affiliates and the other portions of such documents within the reasonable control of GX will comply as to form in all material respects with the requirements of the Securities Act and the Exchange Act. Notwithstanding the foregoing, no representation or warranty is made by GX with respect to statements made or incorporated by reference therein based on information supplied by or on behalf of Company for inclusion or incorporation by reference in the Form S-4 or the Joint Proxy Statement.

4.6              Absence of Certain Changes. Since December 31, 2021, there have been no changes, effects, conditions, events, circumstances, occurrences or developments that, individually

or in the aggregate, have had or would reasonably be expected to have a GX Material Adverse Effect.

No suspension or cancellation of any of the GX Permits is pending or, to the Knowledge of the Company, threatened in writing. GX is in compliance with the terms of the GX Permits and all applicable Laws enacted, promulgated or entered by any Governmental Entity relating to GX or its businesses or properties, except where the failure to be in compliance with such GX Permits or applicable Laws, individually or in the aggregate, would not reasonably be expected to have a GX Material Adverse Effect.

GX has complied in all respects with the terms of the Trust Agreement and is not in breach thereof or default thereunder and there does not exist under the Trust Agreement any event which, with the giving of notice or the lapse of time, would constitute such a breach or default by GX or, to the Knowledge of GX, by the Trustee. There are no separate contracts, side letters or other arrangements or understandings (whether written or unwritten, express or implied) that would cause the description of the Trust Agreement in the GX Public Disclosure Record to be inaccurate in any material respect and/or that would entitle any Person (other than the payment of deferred underwriting commissions to the IPO Underwriter and applicable taxes as described in the GX Public Disclosure Record and the payment to GX Public Shareholders who elect to redeem their Class A Shares pursuant to the GX Charter), to any portion of the proceeds in the Trust Account. Prior to the Closing, none of the funds held in the Trust Account will have been released, except to cover any tax obligation owed by GX as a result of assets of GX or interest or other income earned, and upon the exercise of Redemption Rights pursuant to the GX Charter. As of the date of this Agreement, there are no Actions pending or, to the Knowledge of GX, threatened in writing with respect to the Trust Account.

5.2              Alternative Acquisitions; Business Combination Proposals.

(a)                The Company will, and will cause the Company Subsidiaries and its and their respective Representatives to immediately cease and terminate, and cause to be terminated, any solicitation, encouragement, discussions, negotiations or other activities with any Person or group (other than GX and its Representatives) that may be ongoing relating to any offer, proposal, expression of interest or inquiry that constitutes, or would reasonably be expected to result in, an Alternative Acquisition (an “Acquisition Proposal”). With respect to any Person or group with whom such discussions or negotiations have been terminated, the Company will, (i) immediately discontinue access to, and disclosure of, all information regarding the Company or any Company Subsidiaries, including any data room and any confidential information, properties, facilities and books and records of the Company or any Company Subsidiary, and (ii) within two Business Days of the execution of this Agreement, request and exercise all rights it has to require that such Person or group promptly return or destroy in accordance with the terms of the applicable confidentiality agreement all information furnished by or on behalf of the Company or any of its Affiliates and use reasonable best efforts to enforce compliance with such request, to the extent the Company has such rights under applicable agreements. The Company represents and warrants that it has not waived any confidentiality, standstill, non-disclosure, non-solicitation or similar agreement, restriction or covenant to which the Company or any Company Subsidiary is a party. The Company also covenants, agrees and confirms that (A) the Company shall take all necessary action to enforce each confidentiality, standstill, non-disclosure, non-solicitation or similar agreement, restriction or covenant to which the Company or any Company Subsidiary is a party or may hereafter become a party in accordance with Section 5.2(c), and (B) neither the Company, nor any Company Subsidiary nor any of their respective Representatives have released or will, without the prior written consent of GX (which may be withheld or delayed in GX’s sole and absolute discretion), release any Person from, or waive, amend, suspend or otherwise modify, such Person’s obligations respecting the Company or any Company Subsidiary under any confidentiality, standstill, non-disclosure, non-solicitation or similar agreement, restriction or covenant to which the Corporation or any Subsidiary is a party (provided that the foregoing will not apply to any commercial contract unrelated to an Alternative Transaction, where such confidentiality or non-solicitation restrictions are incidental thereto).

(b)               During the period from the execution of this Agreement until the Closing Date (or earlier termination of this Agreement in accordance with its terms) (the “Interim Period”), the Company will not, and will cause the Company Subsidiaries and its and their respective Representatives not to, directly or indirectly, (i) initiate, solicit, assist, encourage or otherwise facilitate any inquiries or requests for information with respect to or the making of any inquiry regarding, or any proposal or offer that constitutes, or would reasonably be expected to result in, an Acquisition Proposal, (ii) engage in, enter into, continue or otherwise participate in any discussions or negotiations with any Person (other than GX and its Representatives) with respect to, or provide access to its properties, books and records or any non-public information or data

concerning the Company or any of its Affiliates to any Person (other than GX and its Representatives) relating to, any proposal or offer that constitutes, or would reasonably be expected to result in, an Acquisition Proposal (for avoidance of doubt, it being understood that the foregoing will not prohibit the Company or its Representatives from making such Person aware of the restrictions of Section 5.2(a)-(f) (the “Section 5.2 Company Provisions”) in response to the receipt of an Acquisition Proposal), (iii) approve, endorse or recommend, or propose publicly to approve, endorse or recommend, any Alternative Proposal, (iv) execute or enter into any letter of intent, memorandum of understanding, agreement in principle, confidentiality agreement (other than an Acceptable Confidentiality Agreement executed in accordance with Section 5.2(c)), acquisition agreement, merger agreement or similar agreement relating to an Acquisition Proposal (in each case, whether or not legally binding) or (v) resolve or agree to do any of the foregoing.

(c)                Notwithstanding anything in this Agreement to the contrary, if at any time prior to obtaining the Company Shareholder Approval, the Company Board receives a bona fide written Acquisition Proposal that did not result from a breach of this Agreement (including as a result of actions taken by any Representative of the Company that would have constituted a breach of the Section 5.2 Company Provisions if such actions had been taken by the Company) and the Company Board determines in good faith (after consultation with its outside financial advisors and outside legal counsel) that such Acquisition Proposal constitutes or would reasonably be expected to constitute a Superior Proposal, subject to the Company having been, and continuing to be in compliance with the Section 5.2 Company Provisions, the Company and its Representatives may (i) furnish information with respect to the Company and its Subsidiaries to the Person (or group of Persons) making such proposal (and such Person’s or group’s, as the case may be, Representatives) subject to having entered into an Acceptable Confidentiality Agreement, and (ii) participate in discussions or negotiations regarding such proposal with the Person (or group of Persons) making such proposal and such Person’s or group’s, as the case may be, Representatives; provided that the Company shall provide to GX any material non-public information, documentation or data that is provided to any Person given such access that was not previously made available to GX prior to or substantially concurrently with the time it is provided to such Person (and in any event within 24 hours thereof). For purposes of this Agreement, a “Superior Proposal” means any bona fide written Acquisition Proposal made after the date hereof by any Person or group (other than GX and its Representatives) to enter into an Alternative Acquisition that (A) did not result from a breach of the Section 5.2 Company Provisions (including as a result of actions taken by any Representative of the Company that would have constituted a breach of the Section 5.2 Company Provisions if such actions had been taken by the Company), (B) is, based on a good faith determination of the Company Board (after consultation with its outside financial advisors and outside legal counsel), in the best interest of the Company and more favorable, from a financial point of view, to the Company than the transactions contemplated by this Agreement, taking into account all relevant factors (including any changes to this Agreement that may be proposed by GX in response to such Acquisition Proposal), (C) is determined in good faith by the Company Board (after consultation with its outside financial advisors and outside legal counsel) to be reasonably likely to be completed in accordance with its terms without undue delay, taking into account all financial, regulatory, legal and other aspects of such Acquisition Proposal and does not present a materially greater regulatory risk as compared to the Transactions, (D) provides for 100% cash consideration (and no non-cash consideration) to be paid to Company shareholders in such transaction, at a premium of at least 17.5% per Company Common Share over the higher of (1) the 5-day VWAP of the Company’s trading price on the TSX ending on the Business Day

immediately prior to entering into a definitive merger, business combination or other similar transaction agreement in respect of such Superior Proposal and (2) the publicly disclosed per Company Common Share value of the Transactions, (E) is made by a Person or group of Persons who has demonstrated to the satisfaction of the Company Board, acting in good faith (after consultation with its outside financial advisors and outside legal counsel), that it has (i) adequate cash on hand and/or (ii) fully committed financing in place at the time of execution of the definitive transaction agreement in connection with such Acquisition Proposal from a bank or other recognized and reputable financial institution, fund or organization that makes debt or equity investments or financing as part of its usual activities, and that is not subject to any condition or contingency other than customary closing conditions to complete such Acquisition Proposal at the time and on the basis set out therein, (F) is not subject to any due diligence or to any material additional closing conditions as compared to the Transactions pursuant to this Agreement; provided that, notwithstanding anything in this Agreement to the contrary, no Acquisition Proposal can be a Superior Proposal if such Acquisition Proposal is made by a third party, including a group consisting of joint actors with a third party, that (1) is a related party (as defined under Canadian securities laws) or an Affiliate of the Company, (2) is an issuer whose principal asset is cash, cash equivalents, or its exchange listing, including, without limitation, a special purpose acquisition company (other than GX), (3) has been approached by either GX or the Company, with the consent of the other Party, or (4) has been approached by the Company in connection with the Transaction prior to the receipt by the Company of such Superior Proposal; provided, further, that for purposes of the definition of “Superior Proposal,” the term “Acquisition Proposal” shall have the meaning assigned to such term herein, except that (x) the references to “15% or more” in such definition shall be deemed to be references to “100%” and (y) the references to “assets of the Company and its Subsidiaries which constitute 15% or more of the consolidated net revenues, net income or assets of the Company and its Subsidiaries, taken as a whole” shall be deemed to be references to “all or substantially all of the assets of the Company and its Subsidiaries, taken as a whole”. For purposes of this Agreement, an “Acceptable Confidentiality Agreement” means a confidentiality agreement that contains confidentiality and standstill provisions on terms no less favorable in any substantive respect to the Company than those contained in the Confidentiality Agreement.

(d)               The Company Board will not (and no committee or subgroup thereof will) (i) change, withdraw, withhold, qualify or modify, or publicly propose to change, withdraw, withhold, qualify or modify, or fail to make, the approval or recommendation by the Company Board of the Transactions or this Agreement, (ii) approve, recommend, adopt or otherwise declare advisable, or propose publicly to approve, recommend, adopt or otherwise declare advisable, any Alternative Acquisition, (iii) fail to include in the Joint Proxy Statement the recommendation of the Company Board in favor of this Agreement and the Transactions, (iv) take no position or remain neutral with respect to a publicly announced, or otherwise publicly disclosed, Acquisition Proposal for more than five (5) Business Days (or beyond the second (2^nd) Business Day prior to the date of the Company Shareholder Meeting, if sooner), or (v) fail to publicly reaffirm its recommendation of this Agreement and the Transactions within five business days of GX’s written request to do so (or, if earlier, at least two Business Days prior to the Company Shareholder Meeting) following the public announcement of any Alternative Acquisition (or any material amendment thereof, including any change to the price or form of consideration) provided that GX will not be entitled to make such written request, and the Company Board will not be required to make such reaffirmation, more than once with respect to any particular Alternative Acquisition (any action or failure to act in clauses (i) through (iv) being referred to as a “Company

Recommendation Change”). Notwithstanding the foregoing, subject to Section 5.2(e), in the event that, prior to obtaining the Company Shareholder Approval, the Company Board determines in good faith (after consultation with its outside financial advisors and outside legal counsel) that (A) it has received a Superior Proposal and (B) the failure to make a Company Recommendation Change or terminate this Agreement would be reasonably likely to be inconsistent with the Company Board’s fiduciary duties under applicable Law, the Company Board shall give GX at least five Business Days from the later of the date on which GX received notice of a Superior Proposal in accordance with Section 5.2(e) and the date on which GX received all of the materials referred to in Section 5.2(e) with respect to each new Superior Proposal from the Company (the “Right to Match Period”) advance notice of any action to be taken by the Company Board to enter into or approve the entering into of an agreement in respect of the Superior Proposal and GX shall, during the Right to Match Period, have the right, but not the obligation, to propose in writing to amend the terms of this Agreement. The Company Board shall review in good faith and in consultation with its outside financial advisors and outside legal counsel any proposal by GX to amend the terms of this Agreement and the Transactions in order to determine, in good faith in the exercise of its fiduciary duties (after consultation with its outside financial advisors and outside legal counsel), whether GX’s proposal to amend the terms of this Agreement and the Transactions would result in the Acquisition Proposal not being a Superior Proposal, with respect to which the failure to make a Company Recommendation Change or terminate this Agreement would be reasonably likely to be inconsistent with the Company Board’s fiduciary duties under applicable Law. If requested by GX, the Company will, and will cause its Representatives to, during any Right to Match Period, engage in good faith negotiations with GX and its Representatives to make such adjustments in the terms and conditions of this Agreement so that such Acquisition Proposal would cease to constitute a Superior Proposal. Each successive amendment or modification to any Acquisition Proposal that results in an increase in, or modification of, the consideration (or value of such consideration) to be received by the Company Shareholders or other material terms or conditions thereof shall constitute a new Acquisition Proposal for the purposes of this Section 5.2, and GX shall be afforded a new full five (5) Business Day Right to Match Period from the later of the date on which GX received notice thereof in accordance with Section 5.2(e) and the date on which GX received all of the materials referred to in Section 5.2(e) with respect to each new Superior Proposal from the Company. The Company Board may (A) effect a Company Recommendation Change in respect of a Superior Proposal or (B) terminate this Agreement in accordance with Section 7.3(b) to enter into an agreement, understanding or arrangement in respect of a Superior Proposal only if (Y) GX does not, prior to the expiry of the Right to Match Period, propose to amend the terms of this Agreement, or (Z) GX delivers to the Company, prior to the expiry of the Right to Match Period, a proposal to amend the terms of this Agreement as contemplated in this Section 5.2(d), and thereafter the Company Board determines, in good faith in the exercise of its fiduciary duties (after consultation with its outside financial advisors and outside legal counsel), taking into account GX’s proposal to amend this Agreement, that (1) the Acquisition Proposal remains a Superior Proposal and (2) the failure to make a Company Recommendation Change or terminate this Agreement would be reasonably likely to be inconsistent with the Company Board’s fiduciary duties under applicable Law. It is understood and agreed that any amendment to any material term or condition of any Superior Proposal will require a new notice and a new Right to Match Period that will expire five Business Days following delivery of such new notice from the Company to GX.

(e)                In addition to the obligations of the Company set forth in the Section 5.2 Company Provisions, the Company will promptly advise GX, at first orally and then in any event within 24 hours in writing of receipt or otherwise becoming aware thereof, of any request for information, proposal or inquiry relating to, or that would reasonably be expected to result in, an Alternative Acquisition, the material terms and conditions of such request, proposal or inquiry (including any changes thereto), the identity of the Person making such request, proposal or inquiry and copies of all written documents, correspondence or other material received in respect of, from or on behalf of any such Person. The Company will keep GX fully informed of the status and details (including amendments or proposed amendments) of any such request, proposal or inquiry on a prompt basis and shall promptly provide to GX copies of all material correspondence if in writing or electronic form, and if not in writing or electronic form, a description of the material or substantive terms of such correspondence communicated to the Company by or on behalf of any Person making such Acquisition Proposal, inquiry, proposal, offer or request and shall respond as promptly as practicable to all inquiries by GX with respect thereto. Following the Company Board’s good faith determination (after consultation with its outside financial advisors and outside legal counsel) that (i) it has received a Superior Proposal in accordance with Section 5.2(c) and (ii) the failure to make a Company Recommendation Change or terminate this Agreement would be reasonably likely to be inconsistent with the Company Board’s fiduciary duties under applicable Law, the Company shall promptly, and in any event within 24 hours of such determination, deliver to GX a written notice of the determination of the Company Board that such Acquisition Proposal constitutes a Superior Proposal and of the intention of the Company Board to enter into such definitive agreement with respect to such Superior Proposal and to make a Company Recommendation Change, along with a complete copy of the definitive agreement for the Superior Proposal and all material supporting documentation, including any financing documents supplied to the Corporation in connection therewith. During any Right to Match Period, the Company shall discuss and negotiate in good faith and make its Representatives available to discuss and negotiate in good faith (in each case to the extent GX desires to negotiate) with GX and GX’s Representatives any proposed modifications to the terms and conditions of this Agreement or the Transactions so that the Acquisition Proposal does constitute a Superior Proposal, with respect to which the failure to make a Company Recommendation Change or terminate this Agreement would no longer be reasonably likely to be inconsistent with the Company Board’s fiduciary duties under applicable Law.

(f)                Nothing contained in this Agreement shall prohibit the Company Board, acting in good faith and upon advice of its outside financial advisors and outside legal counsel, from making any disclosure to Company Pre-Closing Shareholders as required by applicable Laws, including complying with section 2.17 of National Instrument 62-104 – “Take-Over Bids and Issuer Bids” of the Canadian Securities Administrators, as it may be amended from time to time, and similar provisions under applicable U.S. securities Laws relating to the provision of a directors’ circular in respect of an Acquisition Proposal; provided, however, that neither the Company nor the Company Board shall fail to reaffirm its recommendation of this Agreement and the Transactions in any such disclosure, or be permitted to recommend that the Company Pre-Closing Shareholders tender any securities in connection with any take-over bid that is an Acquisition Proposal or effect a Company Recommendation Change with respect thereto except as permitted by this Section 5.2.

(g)               The Company Board shall promptly reaffirm the Company Recommendation by press release after any Acquisition Proposal which is not determined to be a Superior Proposal is

publicly announced or publicly disclosed or the Company Board determines that a proposed amendment to the terms of this Agreement or the Transactions as contemplated under Section 5.2(d) would result in an Acquisition Proposal no longer being a Superior Proposal. The Company shall provide GX and its outside legal with a reasonable opportunity to review the form and content of any such press release and shall make all reasonable amendments to such press release as requested by GX and its outside legal counsel.

(h)               GX will, and will cause its Representatives to, immediately cease any discussions or negotiations with any Person or group (other than the Company and its Representatives) that may be ongoing relating to any offer, proposal, expression of interest or inquiry with respect to an alternative Business Combination (as defined in the GX Charter) (a “Business Combination Proposal”). With respect to any Person or group with whom such discussions or negotiations have been terminated, GX will request that such Person or group promptly return or destroy all information furnished by or on behalf GX or any of its Affiliates and use reasonable best efforts to enforce compliance with such request. During the Interim Period, GX (i) will not authorize, direct or permit any Representatives to, (A) initiate, solicit or knowingly encourage the making of any proposal or offer that constitutes, or would reasonably be expected to result in, a Business Combination Proposal, (B) engage in, enter into, continue or otherwise participate in any discussions or negotiations with any Person with respect to, or provide any non-public information or data concerning GX or any of its Affiliates to any Person relating to, any proposal or offer that constitutes, or would reasonably be expected to result in, a Business Combination Proposal (for avoidance of doubt, it being understood that the foregoing will not prohibit GX or its Representatives from making such Person aware of the restrictions of this Section 5.2(h) in response to the receipt of a Business Combination Proposal), or (C) enter into any acquisition agreement, merger agreement or similar definitive agreement, or any letter of intent, memorandum of understanding or agreement in principle or any other agreement relating to a Business Combination Proposal.

5.3              Interim Operations of GX. Except (i) as consented to in writing by the Company or (ii) as contemplated by this Agreement or any Ancillary Agreement (including with respect to the Contemplated Financing), GX covenants that, from the date of this Agreement until the earlier of the termination of this Agreement in accordance with its terms and the Closing Date:

(a)                GX will (i) use reasonable best efforts to conduct business, in all material respects, in the ordinary course of business consistent with past practice and (ii) to the extent consistent with the foregoing, use reasonable best efforts to (A) preserve intact its current business organization and (B) maintain its existing relationships with its employees and other Persons with whom GX has material business relations; except that no action or failure to take action by GX with respect to matters specifically addressed by any provision of Section 5.3(b) will constitute a breach under this Section 5.3(a) unless such action or failure to take action would constitute a breach of such provision of Section 5.3(b), as applicable;

(b)               GX will not:

(i)                 amend its organizational documents (other than with respect to the GX Resolutions or with respect to an Extension);

(ii)               seek any approval from GX Shareholders (other than with respect to the GX Resolutions or with respect to an Extension);

(iii)             declare, set aside, authorize, make or pay any dividends on or make any distribution with respect to its capital stock (whether in cash, assets, stock or other securities of GX);

(iv)             issue, sell, pledge, dispose of or encumber or subject to any Lien, or authorize the issuance, sale, pledge, disposition or encumbrance of or otherwise amend the terms of, any equity interests or interests convertible into or exchangeable for equity interests, or any rights, warrants or options to acquire or with respect to equity interests or convertible or exchangeable securities;

(v)               split, combine or reclassify, or redeem, purchase or otherwise acquire, directly or indirectly, any equity interests of GX, other than with respect to the Contemplated Financing;

(c)                Notwithstanding the foregoing, nothing in this Agreement or otherwise will require any Party to agree to any arrangement wherein the Company, GX, Merger Sub or the Second Merger Surviving Company or any of their Affiliates would be required to sell, hold separate or otherwise dispose of or conduct its business in a manner which would resolve such actions or proceedings (or agree to do any of the foregoing) to resolve such action or proceeding or threat thereof so that the Transactions may be consummated, and nothing in this Section 5.4 will limit a Party’s right to terminate this Agreement pursuant to Article VII.

5.7              Listing.

Thereafter until the Closing Date (or the earlier termination of this Agreement in accordance with Article VII), neither the Company nor GX will issue or cause the publication of any press release or similar public statement with respect to, or otherwise make any public statement concerning, this Agreement, the Mergers or the other Transactions that is inconsistent with such prior release in any material respect without the prior written consent of the other Party; provided, however, that, in the case of any release or public statement (a) in connection with any dispute between the Parties regarding this Agreement or the Transactions or (b) as a Party may in good faith determine is required by Law or listing requirements, GX or the Company, as applicable, will use its reasonable best efforts to coordinate such release or public statement with the other Party, prior to publishing such press release or public announcement (except to the extent such press release or public statement is consistent with any prior release previously approved by the other Party).

5.9              Tax Matters.

(a)                All transfer, documentary, sales, use, registration and property transfer or gains tax, stamp tax, excise tax, equity transfer tax, or other similar Taxes imposed in connection with the Transactions (collectively, “Transfer Taxes”), shall be borne and paid by the Person required to pay under applicable Law. The Parties agree to cooperate in the filing of any Tax Returns with respect to the Transfer Taxes.

(b)               GX and the Company shall cooperate, and shall cause their respective Affiliates to cooperate, with respect to Tax matters relating to the Transactions, including by maintaining records and making records available to each other (for inspection, review and copying), making personnel available as reasonably required, and furnishing powers of attorney or other approvals or similar documents necessary or helpful for to address Tax matters or minimize applicable Taxes (all such activities to be conducted (i) during normal business hours and (ii) at the expense of the requesting Party to the extent there are any necessary and material costs to the non-requesting Parties).

(c)                Notwithstanding anything to the contrary contained in this Agreement or any Ancillary Agreement, the Company and its Subsidiaries shall be permitted to take actions prior to, on, or after the Closing Date, as is necessary or helpful in the reasonable judgment of the Company in order to (i) cease to qualify as, or mitigate any impact from qualification as, a passive foreign investment company under section 1297 of the Code for any taxable year, or (ii) retain or address any Tax incentive, abatement, holiday or similar agreement or arrangement; provided that, without the written consent of GX (not to be unreasonably withheld, conditioned, or delayed), no such action shall be permitted to be taken on or before the Closing Date if such action would reasonably be expected to result in any non-de minimis increase in any Party’s (or its members’ or shareholders’) Tax costs, any non-de minimis adverse impact with respect to any Party’s (or its members’ or shareholders’) economic position, or any non-de minimis delay in the consummation of the Transactions. The Company shall consider in good faith and confer with GX regarding any actions proposed by GX in order to accomplish the results described in clause (i) or (ii) of the foregoing sentence.

(d)               Notwithstanding anything to the contrary contained in this Agreement or any Ancillary Agreement, the Parties recognize that the structure of the Transactions is subject to continuing review and analysis in light of tax, accounting, governance and other considerations.

(e)                Certain Excise Tax Matters.

(i)                 The Parties shall, beginning at least sixty (60) days prior to the anticipated Closing Date, cooperate in good faith to agree upon a reasonable formula (the “Excise Tax Formula”) that, when applied to the final number of Redemption Shares (taking into account any reversals of redemptions prior to the GX Shareholder Meeting) will estimate GX’s Tax liability under Section 4501 of the Code that will be incurred as a result of the Transactions (taking into account stock issuances that are part of the Transactions, and other available offsets, if any, to the extent such issuances and offsets are expected to actually reduce such Tax liability) (such Tax liability, the “Excise Tax Amount”).  The Excise Tax Formula shall (i) take into account only the Transactions, (ii) not take into account any stock issuances that are not part of the Transactions, (iii) not take into account the time value of money or whether the Excise Tax Amount, as of the Closing Date, is or could be deferred for a period of time, in each case, except to the extent the expected date of payment of the Excise Tax Amount is later than December 31, 2026, (iv) not take into account whether the Excise Tax Amount, Section 4501 of the Code or the Treasury regulations thereunder are or could be the subject of a proceeding, controversy, litigation, or appeal, and (v) be determined in accordance with any IRS/Treasury regulations or other

formal guidance regarding the application of Section 4501 of the Code (including any such regulations or formal guidance issued after the date hereof).

(ii)               In the event that the Parties are unable to agree on the Excise Tax Formula thirty (30) days prior to the anticipated Closing Date, then the dispute shall be referred to a Tax Advisor mutually acceptable to each of the Parties in order to determine the Excise Tax Formula in consultation with the Parties. The Excise Tax Formula shall be determined as soon as is practicable, but in no event later than twenty (20) days after the appointment of the Tax Advisor. The resolution of the Excise Tax Formula by the Tax Advisor shall be conclusive and binding on the Parties. For purposes of this Section 5.09(e)(ii) and the definition of Closing Cash, (1) “Tax Advisor” means a nationally recognized public accounting firm that is independent of the Parties and (2) all assets in the Trust Account shall count as Closing Cash in the manner described in clause (a) of the definition thereof.

5.10          Expenses. Except as expressly provided herein, whether or not the Transactions are consummated, all costs and expenses incurred in connection with this Agreement and the Transactions will be paid by the Party incurring such expense, except that from and after the Closing, the Company shall be liable for and pay the transaction expenses incurred by any Party accruing prior to and through the Closing and not otherwise paid prior to the Closing, which the Company shall pay or cause to be paid by wire transfer of immediately available funds (provided that, for the avoidance of doubt, any expenses of Sponsor will not be considered to be expenses of any Party).

5.11          Preparation of the Form S-4 and the Joint Proxy Statement.

(a)                As promptly as reasonably practicable after the execution of this Agreement, (i) GX and the Company will jointly prepare the Joint Proxy Statement in preliminary form and (ii) the Company will prepare (with GX’s reasonable cooperation) and file with the SEC, the Canadian Securities Administrators and the TSX the Form S-4 (which shall include the Joint Proxy Statement), in a form mutually acceptable to the Parties. Each of GX and the Company will use its reasonable best efforts to ensure that the Form S-4, including the Joint Proxy Statement, complies as to form in all material respects with the rules and regulations promulgated by the SEC under the Exchange Act and the Securities Act and with all other applicable Law (including the BCBCA and any applicable Canadian Securities Laws). The Company will ensure that the Joint Proxy Statement includes the opinion of the Company Financial Advisor referred to in Section 3.23. Subject to Section 5.2, the Joint Proxy Statement shall include the Company Board’s recommendation that the Company Pre-Closing Shareholders adopt the Company Resolutions. The Joint Proxy Statement shall include the GX Board’s recommendation that the GX Shareholders adopt the GX Resolutions. GX and the Company will use their respective reasonable best efforts to cause the Form S-4 to be declared effective under the Securities Act as promptly as practicable after such filing (including by responding to comments of the SEC or any Canadian Securities Administrator) and to keep the Form S-4 effective as long as is necessary to consummate the Transactions. No party will file or mail any such document prior to receiving the approval of the other, which approval shall not be unreasonably withheld, conditioned or delayed. GX and the Company shall make all necessary filings with respect to the Transactions under the Securities Act and the Exchange Act, the BCBCA and any necessary state or Canadian Securities Laws or “blue sky” notice requirements in connection with the issuance of (i) the Company Post-Closing

Common Shares issuable pursuant to the Exchange, (ii) the Company Common Shares issuable upon the exchange of the Second Merger Class B Shares pursuant to the Exchange Agreement, (iii) the Company Common Shares issuable upon the exercise of Former GX Company Warrants, and (iv) the Former GX Company Warrants, in each case pursuant to this Agreement.

As promptly as practicable after the Form S-4 shall have become effective, each of GX and the Company shall use its reasonable best efforts to cause the Joint Proxy Statement and all other customary proxy or other materials for meetings such as the Company Shareholder Meeting and the GX Shareholder Meeting, as applicable, to be mailed to the Company Pre-Closing Shareholders and the GX Shareholders, as applicable.

(b)               Each of GX and the Company shall furnish all information concerning such Party and its Affiliates to the other, and provide such other assistance, as may be reasonably requested by such other Party and shall otherwise reasonably assist and cooperate with the other in the preparation, filing and distribution of the Joint Proxy Statement, the Form S-4, and the resolution of any comments either received from the SEC or any Canadian Securities Administrator.

(c)                If at any time prior to the later of the receipt of the Company Shareholder Approval and GX Shareholder Approval, any information relating to the Company or GX, or any of their respective Affiliates, directors or officers, should be discovered by the Company or GX which is required to be set forth in an amendment or supplement to either the Form S-4 or the Joint Proxy Statement, so that either such document would not include any misstatement of a material fact or omit 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, not misleading, or any misrepresentation, the Party which discovers such information shall promptly notify the other Party and an appropriate amendment or supplement describing such information shall be promptly filed with the SEC and the Canadian Securities Administrators and, with respect to the Joint Proxy Statement, to the extent required by applicable Law, disseminated to the Company Pre-Closing Shareholders and GX Shareholders, as applicable, provided in each case that the delivery of such notice and the filing of any such amendment or supplement shall not affect or be deemed to modify any representation or warranty made by any party hereunder or otherwise affect the remedies available hereunder to any party.

(d)               The Parties shall notify each other promptly of the receipt of any comments, whether written or oral, from the SEC, or any Canadian Securities Administrator or their respective staff and of any request by the SEC, or any Canadian Securities Administrator or their respective staff for amendments or supplements to the Joint Proxy Statement or the Form S-4 or for additional information and shall supply each other with copies of (i) all correspondence between it or any of its Representatives, on the one hand, and the SEC, or any Canadian Securities Administrator or their respective staff, on the other hand, with respect to the Joint Proxy Statement or the Form S-4 and (ii) all stop orders of the SEC or of or any Canadian Securities Administrator relating to the

Joint Proxy Statement, or the Form S-4. Each Party shall give the other Party and its counsel a reasonable opportunity to participate in preparing the proposed response by such Party to comments received from the SEC, any Canadian Securities Administrator or their respective staff and to provide comments on any proposed response thereto, and such Party shall give reasonable consideration to any such comments and shall not respond to the SEC or the Canadian Securities Administrator prior to receiving the approval of the other, which approval shall not be unreasonably withheld, conditioned or delayed. Each Party shall use reasonable best efforts to respond promptly to any comments of the SEC, or any Canadian Securities Administrator or their respective staff with respect to the Joint Proxy Statement or the Form S-4, as applicable. No amendment or supplement to the Joint Proxy Statement or the Form S-4 will be made by GX or the Company without the approval of the other Party, which approval shall not be unreasonably withheld, conditioned or delayed; provided that the Company, in connection with a Company Recommendation Change made in compliance with the terms hereof may (and GX shall comply with any request by the Company to) amend or supplement the Joint Proxy Statement (including by incorporation by reference) pursuant to an amendment or supplement (including by incorporation by reference) to the extent it contains (i) a Company Recommendation Change, (ii) a statement of the reason of the Company Board for making such a Company Recommendation Change, and (iii) additional information reasonably related to the foregoing.

Without limiting the foregoing, the Company will, and will cause the Second Merger Surviving Company and its other Subsidiaries to, (i) maintain for a period of not less than six years following the Closing provisions in its certificate of incorporation (if applicable), bylaws and other organizational documents concerning the indemnification and exculpation (including provisions relating to expense advancement) of officers and directors with respect to acts or omissions occurring prior to the Closing that are no less favorable to those Persons than the provisions of such certificates of incorporation (if applicable), bylaws and other organizational documents as of the date of this Agreement and (ii) not amend, repeal or otherwise modify such provisions in any respect that would adversely affect the rights of those Persons thereunder, in each case, except as required by Law.

(b)               For a period of six years from the Closing, the Company will, or will cause one or more of its Subsidiaries to, maintain in effect directors’ and officers’ liability insurance covering those Persons who are currently covered by GX’s, the Company’s or its Subsidiaries’ directors’ and officers’ liability insurance policies (true, correct and complete copies of which have been heretofore made available to the Company or its Representatives) on terms not less favorable than the terms of GX’s current insurance coverage; provided, however, that (i) GX will cause coverage to be extended under its current directors’ and officers’ liability insurance (covering those Persons who are currently covered by GX’s, the Company’s or its Subsidiaries’ directors’ and officers’ liability insurance policies) by obtaining a six-year “tail” policy containing terms not materially less favorable than the terms of such current GX insurance coverage with respect to claims existing or occurring at or prior to the Closing, and the cost of such “tail” policy shall constitute a Cash Transaction Expense, except that in no event will GX, the Company or its Subsidiaries be required to pay a premium for such insurance in excess of 250% of the aggregate premium currently payable by GX for such insurance policy (unless, prior to the Closing, the Parties identify a more cost effective policy which satisfies this covenant, in which case, the Parties may cause such coverage to be effectuated under such alternative policy instead), and (ii) if any claim is asserted or made within such six-year period, any insurance required to be maintained under this Section 5.14 will be continued in respect of such claim until the final disposition thereof.

(c)                On the Closing Date, to the extent not already entered into, the Company shall enter into customary indemnification agreements reasonably satisfactory to each of the Company and GX with the Closing Directors and Officers, which indemnification agreements shall continue to be effective following the Closing.

(d)               In the event that the Company or any of its successors or assigns consolidates with or merges into any other Person and is not the continuing or surviving company or entity of such consolidation or merger or transfers or conveys all or substantially all of its properties and assets to any Person, then, and in each such case, the Company will ensure that proper provision will be made so that the successors and assigns of the Company will succeed to the obligations set forth in this Section 5.14.

5.15          Trust Account Release. Prior to or at the Closing (subject to the satisfaction or waiver of the conditions set forth in Section 6.1 and Section 6.3), GX will make appropriate arrangements to cause the funds in the Trust Account to be disbursed in accordance with the Trust Agreement for the following: (a) all amounts payable to GX Public Shareholders who have validly exercised Redemption Rights; (b) the payment of outstanding transaction expenses; and (c) after the Second Merger Effective Time, the balance of the assets in the Trust Account to be distributed to the Second Merger Surviving Company.

5.16          Stock Exchange Delisting; Deregistration. Prior to the Closing Date, each of the Parties shall cooperate with the other Parties and use its reasonable best efforts to take, or cause to be taken, all actions, and do or cause to be done all things, reasonably necessary, proper or advisable on its part under applicable Law and the rules and regulations of NASDAQ to enable the delisting by the Second Merger Surviving Company of the Class A Shares, GX Public Units and GX Public Warrants from NASDAQ and the deregistration of the Class A Shares, GX Public Units and GX Public Warrants under the Exchange Act as promptly as practicable after the Closing.

5.17          Certain Section 16 Matters. Before the Closing, the Company Board, or a committee thereof composed solely of two or more “Non-Employee Directors” (as defined in Rule 16b-3(b)(3)(i) under the Exchange Act), will adopt a resolution consistent with interpretive guidance of the SEC such that the acquisition of Transaction Consideration Shares pursuant to this Agreement and the other agreements contemplated hereby, by any person owning securities of GX who is expected to become a director or officer (as defined in Rule 16a-1(f) under the Exchange Act) of the Company following the Closing, will be an exempt transaction for purposes of Section 16(b) of the U.S. Exchange Act pursuant to Rule 16b-3 thereunder.

5.18          Financing.

(a)                In connection with the Transactions, (x) each of GX and the Company intends to enter into, at or prior to Closing, (i) a facility for up to $20,000,000 on terms no less favorable to the Company than the Convertible Security Funding Agreement, (ii) a committed equity facility substantially on the terms set forth in the Non-Binding Standby Equity Purchase Agreement Term Sheet dated as of the date hereof among the Parties and Yorkville Advisors Global, LP (the “CEF Facility”), and (iii) a facility substantially on the terms set forth in the Non-Binding Unsecured Convertible Debenture Term Sheet dated as of the date hereof among the Parties and Yorkville

Advisors Global, LP (the “Convertible Notes”) and (y) if, acting reasonably, the Parties determine that so doing would be in the best interest of the post-Closing Company, each of GX and the Company intends to pursue a private placement financing for the purpose of entering into one or more subscription agreements with certain investors, pursuant to which such investors will purchase Company Common Shares, in each case, to be consummated prior to the First Merger and/or enter into one or more additional financing arrangements, on terms reasonably satisfactory to the Parties (collectively, the “Contemplated Financing”).

(b)               Each of GX and the Company will use its reasonable best efforts to provide all customary and reasonable cooperation in connection with the entry into the CEF Facility and the Convertible Notes, in each case, to the extent (1) not entered into prior to the date of this Agreement and (2) necessary to provide financing to the Company if Closing Cash would not otherwise equal or exceed the Closing Cash Minimum, as may be reasonably requested by the other Party, including (i) participation at reasonable times in a reasonable number of meetings, presentations, roadshows (including customary one-on-one meetings), rating agency and due diligence sessions with potential lenders or investors or other potential financing sources (the “Financing Sources”), including direct contact between senior management of the Parties and the other representatives of the Parties, on the one hand, and the actual and potential Financing Sources, on the other hand, in each case with reasonable advance notice, (ii) reasonably assisting the other Party in the preparation of customary materials for rating agency presentations and lender and investor presentations, business projections, pro forma financial statements, bank books and other marketing documents customarily used to arrange such financing, and identifying any portion of the information contained therein that would constitute material, non-public information with respect to the Parties or any of their respective securities for purposes of foreign, United States federal or state securities laws, (iii) as soon as reasonably practicable following the date hereof, preparing and effecting the filing of, or as soon as reasonably practicable following the request of the other Party furnishing the other Party with the information regarding such Party that is customary or necessary for the preparation and filing of, a registration statement and prospectus for the issuance and sale of securities, or the resale of securities issued or underlying securities issued or issuable, in connection with the Convertible Notes or CEF Facility, as necessary to effect the registration of such securities, (iv) to the extent requested by a Financing Source at least ten (10) days prior to the Closing, furnishing within five days prior to the Closing all documentation and other information required under applicable “know your customer” and anti-money laundering rules and regulations, including the U.S.A. Patriot Act of 2001, (v) assisting in the preparation of definitive financing documents as may be reasonably requested by the other Party, (vi) reasonably cooperating in satisfying the conditions precedent set forth in the term sheets for the Convertible Notes and the CEF Facility to the extent the satisfaction of such condition requires the cooperation of, or is within the control of the such Party, (vii) taking all corporate actions, subject to the occurrence of the Closing, as reasonably requested by the other Party to permit the consummation of the Convertible Notes and the CEF Facility, and (viii) permitting the actual and potential Financing Sources to conduct customary due diligence, subject to customary non-disclosure and confidentiality agreements or customary wall cross scripts. Each Party will provide the other Party with drafts of documents pursuant to which the Convertible Notes and the CEF Facility will be effectuated and consider any comments provided by the other Party in good faith.  Each of the Company and GX will, and will cause its respective Representatives to, cooperate with the other Party and its Representatives in connection with the Convertible Notes and the CEF Facility and any other Contemplated Financing.

(c)                Each of GX and the Company agree to work together in good faith to determine whether one or more of the arrangements comprising the Contemplated Financing should not be pursued to the extent sufficient capital is raised from one or more of the other financing arrangements and, if such decision is made, the Parties agree to amend the definition of Contemplated Financing accordingly.

(d)               If, and to the extent, required by any underwriter, placement agent, financial advisor, capital markets advisor or other adviser to GX and/or the Company, each of GX and the Company will use its reasonable best efforts to deliver, in connection with the effectiveness of the Form S-4 and the occurrence of the Company Shareholder Meeting and the GX Shareholder Meeting, reasonable and customary (i) comfort letters from the independent certified public accounting firms of each of GX and the Company and (ii) negative assurance letters of outside counsel to each of GX and the Company.

(e)                Notwithstanding anything in this Section 5.18 to the contrary, none of the Contemplated Financing shall require (A) the Sponsor to forfeit or transfer any Founder Shares or (B) GX or the Company to take any actions that would reasonably be expected to prevent, materially delay or materially impede the consummation of the Transactions.

5.19          Transaction Litigation. From and after the date of this Agreement until the earlier of the Closing or termination of this Agreement in accordance with its terms, GX, on the one hand, and the Company, on the other hand, shall, to the extent permitted by applicable Law, each notify the other in writing promptly after learning of any shareholder demands or other shareholder Actions (including derivative claims) relating to this Agreement, any Ancillary Agreement or any matters relating hereto or thereto (collectively, the “Transaction Litigation”) commenced against, in the case of GX, GX or any of its representatives (in their capacity as such) or, in the case of the Company, the Company, its Subsidiaries or any of their respective representatives (in their capacity as such). GX and the Company shall each (i) keep the other reasonably informed regarding any Transaction Litigation, (ii) give the other the opportunity to, at its own cost and expense, participate in the defense, settlement and compromise of any such Transaction Litigation and reasonably cooperate with the other in connection with the defense, settlement and compromise of any such Transaction Litigation, including by providing it with a reasonable opportunity to offer timely comments, suggestions or advice with respect to such Transaction Litigation and considering in good faith such timely comments, suggestions or advice with respect to such Transaction Litigation, (iii) consider in good faith the other’s advice with respect to any such Transaction Litigation and (iv) reasonably cooperate with each other.

(iii)             If this Agreement shall have been validly terminated pursuant to (A) Section 7.4(a) as a result of a willful and material breach by the Company (including, without limitation a willful and material breach of the Section 5.2 Company Provisions (including as a result of actions taken by any director of the Company that would have constituted a willful and material breach of the Section 5.2 Company Provisions if such actions had been taken by the Company)), (B) Section 7.4(c) or (C) any other provision of Section 7.2, Section 7.3 or Section 7.4 if, at such time, GX shall have had the right to terminate this Agreement pursuant to Section 7.4(a) as a result of a willful and material breach by the Company (including, without limitation a willful and material breach of the Section 5.2 Company Provisions (including as a result of actions taken by any director of the Company that would have constituted a willful and material breach of the Section 5.2 Company

Provisions if such actions had been taken by the Company)) or Section 7.4(c) then, in each case, the Company shall pay to GX a termination fee in the amount of $25,000,000 (the “Intentional Breach Termination Fee”) by wire transfer in immediately available funds to an account designated by GX in which case payment shall be made within two Business Days of such termination, provided that in no event will GX be entitled to both the Intentional Breach Termination Fee and the Base Termination Fee.

(iv)             If this Agreement shall have been validly terminated and the Base Termination Fee or the Intentional Breach Termination Fee is payable by the Company to GX in accordance with the terms hereof, then in addition to the Base Termination Fee or the Intentional Breach Termination Fee, as applicable, the Company shall also pay, or cause to be paid to GX, an amount (the “Expense Amount”) equal to the sum of all documented and reasonable out-of-pocket expenses paid or payable by GX and the Sponsor in connection with this Agreement and the Transactions, which Expense Amount shall not exceed $5,000,000, by wire transfer in immediately available funds to an account designated by GX in which case payment shall be made within two Business Days of such termination.

(c)                The Parties acknowledge and hereby agree that the payment of the Base Termination Fee or the Intentional Breach Termination Fee, as applicable, if, as and when required pursuant to this Section 7.5, shall not constitute a penalty but will be liquidated damages, in a reasonable amount that will compensate GX in the circumstances in which it is payable for the efforts and resources expended and opportunities foregone while negotiating this Agreement and in reliance on this Agreement and on the expectation of the consummation of the Transactions, which amount would otherwise be impossible to calculate with precision. Each of the Parties acknowledges that the agreements contained in this Section 7.5 are an integral part of the Transactions and that, without these agreements, the Parties would not enter into this Agreement.

ARTICLE VIII
MISCELLANEOUS AND GENERAL

8.1              No Survival. The representations and warranties of the Parties contained in this Agreement or in any certificate or instrument delivered by or on behalf of the Company, GX or Merger Sub pursuant to this Agreement will not survive the Closing, and from and after the Closing, the Company, the Second Merger Surviving Company and their respective Representatives will not have any further obligations, nor will any claim be asserted or action be brought against the Company, the Second Merger Surviving Company or their respective Representatives with respect thereto. The covenants of the Parties in this Agreement or in any certificate or instrument delivered pursuant to this Agreement, including any rights arising out of any breach of such covenants, will not survive the Closing, except for those covenants contained herein and therein that by their terms apply or are to be performed in whole or in part after the Closing (which such covenants will survive the Closing and continue until fully performed in accordance with their terms).

8.2              Modification or Amendment. Subject to the provisions of applicable Law, at any time prior to the Closing, the Parties may modify or amend this Agreement by written agreement of GX and the Company; provided that any amendment of this Agreement that requires approval

by the Company Pre-Closing Shareholders or the GX Shareholders under applicable Law will be subject to such approval. The failure of any Party to assert any of its rights under this Agreement or otherwise will not constitute a modification, amendment, or waiver of those rights.

8.3              Waiver of Conditions. The conditions to each of the Parties’ obligations to consummate the Transactions are for the sole benefit of such Party and, together with the other provisions of this Agreement for the benefit of such Party, may be waived in writing by such Party, in whole or in part.

8.4              Counterparts; Effectiveness. This Agreement may be executed in any number of counterparts (including by pdf or other readable electronic format), each such counterpart being deemed to be an original instrument, with the same effect as if the signature thereto and hereto were upon the same instrument, and will become effective when one or more counterparts have been signed by each of the Parties and delivered (including by email or DocuSign) to the other Parties, and all such counterparts will together constitute one and the same agreement.

8.5              Governing Law; Venue; Waiver of Jury Trial.

(a)                This Agreement will be construed and enforced in accordance with the Laws of the State of Delaware, without regard to the conflict of laws principles that would result in the application of any Law other than the Law of the State of Delaware.

(b)               Each of the Parties hereby irrevocably and unconditionally submits, for itself and its property, to the exclusive jurisdiction and venue of the Court of Chancery of the State of Delaware (or, to the extent that such court does not have subject matter jurisdiction, the Superior Court of the State of Delaware) or, if it has or can acquire jurisdiction, in the United States District Court for the District of Delaware (collectively, the “Chosen Courts”), in any Action arising out of or relating to this Agreement or the agreements delivered in connection herewith or the Transactions or the transactions contemplated by the Ancillary Agreements or for recognition or enforcement of any judgment relating thereto, and each of the Parties hereby irrevocably and unconditionally (i) agrees not to commence any such Action, except in the Chosen Courts; (ii) agrees that any claim in respect of any such Action may be heard and determined in the Chosen Courts; (iii) waives, to the fullest extent it may legally and effectively do so, any objection that it may now or hereafter have to the laying of venue of any such Action in the Chosen Courts; and (iv) waives, to the fullest extent permitted by Law, the defense of an inconvenient forum to the maintenance of such Action in the Chosen Courts. Each of the Parties agrees that a final judgment in any such Action shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by applicable Law. Each Party irrevocably consents to service of process inside or outside the territorial jurisdiction of the Chosen Courts in the manner provided for notices in Section 8.7. Nothing in this Agreement will affect the right of any Party to this Agreement to serve process in any other manner permitted by applicable Law.

(c)                EACH PARTY HEREBY IRREVOCABLY WAIVES, AND WILL CAUSE ITS SUBSIDIARIES AND AFFILIATES TO WAIVE, ANY AND ALL RIGHTS TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATED TO THIS AGREEMENT OR THE TRANSACTIONS.

8.6              Specific Performance. The Parties agree that irreparable damage for which monetary damages, even if available, would not be an adequate remedy, would occur in the event that the Parties do not perform their obligations under the provisions of this Agreement (including failing to take such actions as are required of them hereunder to consummate this Agreement) in accordance with its specified terms or otherwise breach such provisions. Subject to the other provisions of this Section 8.6, the Parties acknowledge and agree (and further agree not to take any contrary position in any litigation concerning this Agreement) that (a) the Parties will be entitled to an injunction or injunctions, specific performance, or other equitable relief, to prevent breaches of this Agreement and to enforce specifically the terms and provisions hereof (including the obligations of the Parties to consummate the Merger) without proof of damages or otherwise, and that such relief may be sought in addition to and will not limit, diminish or otherwise impair, any other remedy to which they are entitled under this Agreement, (b) the provisions set forth herein are not intended to and do not adequately compensate for the harm that would result from a breach of this Agreement and will not be construed to limit, diminish or otherwise impair in any respect any Party’s right to specific enforcement, and (c) the right of specific enforcement is an integral part of the Transactions and without that right, none of the Parties would have entered into this Agreement. The Parties acknowledge and agree that any Party seeking an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement in accordance with this Section 8.6 will not be required to provide any bond or other security in connection with any such order or injunction. Notwithstanding anything in this Agreement to the contrary, in no event will GX be entitled to receive both (A) a grant of specific performance of the Company’s obligation to consummate the Closing and (B) the Base Termination Fee or the Intentional Breach Termination Fee.

All notices and other communications among the Parties will be in writing and will be deemed to have been duly given (a) when delivered in person, (b) when delivered by FedEx or other nationally recognized overnight delivery service, or (c) when delivered by email (so long as the sender of any such e-mail has not received an e-mail from the applicable server indicating a delivery failure), in each case, according to the instructions set forth below. Such notices will be deemed given: at the time of personal delivery, if delivered in person; one Business Day after being sent, if sent by reputable, overnight delivery service and at the time sent (so long as the sender of any such e-mail has not received an e-mail from the applicable server indicating a delivery failure), if sent by email prior to 5:00 p.m. local time of the recipient on a Business Day; or on the next Business Day if sent by email after 5:00 p.m. local time of the recipient on a Business Day or on a non-Business Day.

8.8              Entire Agreement. This Agreement (including the Company Disclosure Letter, the GX Disclosure Letter and all other annexes and exhibits hereto) and the Ancillary Agreements constitute the entire agreement, and supersede all other prior agreements, understandings, representations and warranties both written and oral, among the Parties, with respect to the subject matter hereof.

8.9              No Third-Party Beneficiaries. The representations, warranties and covenants set forth herein are solely for the benefit of the other Parties hereto, in accordance with and subject to the terms of this Agreement, and this Agreement is not intended to, and does not, confer upon any Person other than the Parties any rights or remedies hereunder, including the right to rely upon the representations and warranties set forth herein, except pursuant to Section 5.14 and Section 8.15 and except for the provisions hereof applicable to Sponsor; provided that the Sponsor is an intended third-party beneficiary of, and may enforce, GX’s rights pursuant to Section 7.5 (including following any liquidation or dissolution of GX).

8.10          Definitions. Each of the terms set forth in Annex A is defined as set forth therein and each of the terms defined elsewhere in this Agreement has the meaning set forth herein.

8.11          Severability. The provisions of this Agreement will be deemed severable and the invalidity or unenforceability of any provision will not affect the validity or enforceability of the other provisions hereof. If any provision of this Agreement, or the application thereof to any Person or any circumstance, is invalid or unenforceable, then (a) a suitable and equitable provision will be substituted therefor in order to carry out, so far as may be valid and enforceable, the intent and purpose of such invalid or unenforceable provision and (b) the remainder of this Agreement and the application of such provision to other Persons or circumstances will not be affected by such invalidity or unenforceability, nor will such invalidity or unenforceability affect the validity or enforceability of such provision, or the application thereof, in any other jurisdiction.

8.12          Interpretation; Construction.

(a)                The headings herein are for convenience of reference only, do not constitute part of this Agreement and will not be deemed to limit or otherwise affect any of the provisions hereof. Where a reference in this Agreement is made to an Article, a Section, Annex or Exhibit, such reference will be to an Article, a Section of, or Annex to Exhibit to this Agreement unless otherwise indicated. Whenever the words “include,” “includes” or “including” are used in this Agreement, they will be deemed to be followed by the words “without limitation.” All pronouns and all variations thereof will be deemed to refer to the masculine, feminine or neuter, singular or plural, as the identity of the Person may require. Where a reference in this Agreement is made to any agreement (including this Agreement), contract, statute or regulation, such references are to, except as context may otherwise require, the agreement, contract, statute or regulation as amended, modified, supplemented, restated or replaced from time to time (in the case of an agreement or

contract, to the extent permitted by the terms thereof); and to any section of any statute or regulation including any successor to the section and, in the case of any statute, any rules or regulations promulgated thereunder. All references to “dollars” or “$” in this Agreement are to United States dollars. All references to “days” will be to calendar days unless otherwise indicated as a “Business Day.” References to documents or other materials “provided” or “made available” to GX or similar phrases will mean that such documents or other materials were present at least one Business Day prior to the date hereof in the electronic data room to which GX and its Representatives have access (the “VDR”) (provided that the construction of such terms in Section 3.27 and Section 4.17 will not be limited by this Section 8.12(a)).

(b)               The Parties have participated jointly in negotiating and drafting this Agreement. In the event that an ambiguity or a question of intent or interpretation arises, this Agreement will be construed as if drafted jointly by the Parties, and no presumption or burden of proof will arise favoring or disfavoring any Party by virtue of the authorship of any provision of this Agreement.

(c)                The mere inclusion of any item in any section or subsection of the Company Disclosure Letter or the GX Disclosure Letter as an exception to any representation or warranty or otherwise will not be deemed to constitute an admission by the Company or by GX, as applicable, or to otherwise imply, that any such item has had or would reasonably be expected to have a Company Material Adverse Effect or a GX Material Adverse Effect, as applicable, or otherwise represents an exception or material development, fact, change, event, effect, occurrence or circumstance for the purposes of this Agreement, or that such item meets or exceeds a monetary or other threshold specified for disclosure in this Agreement. Matters disclosed in any section or subsection of the Company Disclosure Letter or the GX Disclosure Letter are not necessarily limited to matters that are required by this Agreement to be disclosed therein. Headings inserted in the sections or subsections of the Company Disclosure Letter or the GX Disclosure Letter are for convenience of reference only and will not have the effect of amending or changing the express terms of the sections or subsections as set forth in this Agreement.

(d)               Notwithstanding anything to the contrary herein, no representation or warranty by GX in this Agreement shall apply to any statement or information in the GX Public Disclosure Record that relates to the topics referenced in the SEC proposed rules titled “Special Purpose Acquisition Companies, Shell Companies, and Projections” issued on March 30, 2022 or to any other SEC rule, proposed rule, statement, guidance, interpretation or change in presentation issued after the execution of this Agreement and applicable to special purpose acquisition companies (collectively, the “SEC Statement”), nor shall any correction, amendment or restatement of the GX Public Disclosure Record due wholly or in part to the SEC Statement, nor any other effects that relate to or arise out of, or are in connection with or in response to, the SEC Statement or any changes in accounting or disclosure related thereto, be deemed to be a breach of any representation or warranty by GX. Each of the Parties acknowledges and agrees that GX continues to review the SEC Statement and its implications, including on the GX Public Disclosure Record, and any restatement, revision or other modification of the GX Public Disclosure Record relating to or arising from such SEC Statement, shall (i) be deemed not material and not to have or reasonably be expected to have, individually or in the aggregate, a GX Material Adverse Effect and (ii) not itself be deemed to constitute a breach of any representation or warranty of any of the Parties in this Agreement. No breach of any representation or warranty of either Party will be deemed to have occurred solely as a result of the SEC Statement, nor any other effects that relate to or arise

out of, or are in connection with or in response to, the SEC Statement or any changes in accounting or disclosure related thereto.

8.13          Assignment. This Agreement will be binding upon and inure to the benefit of the Parties and their respective successors, legal representatives and permitted assigns. No Party may assign any of its rights or delegate any of its obligations under this Agreement, by operation of Law or otherwise, without the prior written consent of the other Party.

8.14          Waiver of Access to Trust Account. Reference is made to the Final IPO Prospectus. The Company hereby represents and warrants that it understands that GX has established the Trust Account containing the proceeds of its IPO and the overallotment shares acquired by its underwriters and from certain private placements occurring simultaneously with the IPO (including interest accrued from time to time thereon) for the benefit of the GX Public Shareholders, and that, except as otherwise described in the Final IPO Prospectus, GX may disburse monies from the Trust Account only: (a) to the GX Public Shareholders in the event they elect to redeem their GX Shares in connection with the consummation of GX’s Business Combination or in connection with an extension of its deadline to consummate a Business Combination, (b) to the GX Public Shareholders if GX fails to consummate a Business Combination within twenty-four (24) months after the closing of the IPO, subject to extension by an amendment to GX’s organizational documents, (c) with respect to any interest earned on the amounts held in the Trust Account, amounts necessary to pay for any Taxes or (d) to GX (or, as applicable, the Second Merger Surviving Company) after or concurrently with the consummation of a Business Combination. For and in consideration of GX entering into this Agreement, and for other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the Company hereby agrees on behalf of itself and its Affiliates that, notwithstanding anything to the contrary in this Agreement, neither the Company nor any of its Affiliates do now or shall at any time hereafter have any right, title, interest or claim of any kind in or to any monies in the Trust Account or distributions therefrom, or make any claim against the Trust Account (including any distributions therefrom), regardless of whether such claim arises as a result of, in connection with or relating in any way to, this Agreement or any proposed or actual business relationship between GX or its Affiliates, on the one hand, and the Company or its Affiliates, on the other hand, 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”). The Company on behalf of itself and its Affiliates hereby irrevocably waives and releases, and will cause any Affiliate of the Company in connection with the Transactions, to irrevocably waive and release, any Released Claims that the Company or any of its Affiliates may have against the Trust Account (including any distributions therefrom) now or in the future as a result of, or arising out of, any negotiations, contracts or agreements with GX or its Affiliates, and further agrees not to seek any recourse against the Trust Account (including any distributions therefrom) for any Released Claims for any reason whatsoever or to bring any Action or proceedings against the Trust Account or the Trustee. The Company agrees and acknowledges that such irrevocable waiver is material to this Agreement and specifically relied upon by GX and its Affiliates to induce GX to enter into this Agreement, and the Company further intends and understands such waiver to be valid, binding and enforceable against the Company and each of its Affiliates under applicable Law. To the extent the Company or any of its Affiliates commences any action or proceeding based upon, in connection with, relating to or arising out of any Released Claim, which proceeding seeks, in whole or in part,

monetary relief against GX or its Affiliates, the Company hereby acknowledges and agrees that the Company’s and its Affiliates’ sole remedy shall be against funds held outside of the Trust Account and that such claim shall not permit the Company or its Affiliates (or any person claiming on any of their behalf or in lieu of any of them) to have any claim against the Trust Account (including any distributions therefrom) or any amounts contained therein.

8.15          No Recourse. Except in the case of fraud, all Actions (whether in contract or in tort, in law or in equity, or granted by statute whether by or through attempted piercing of the corporate, limited partnership or limited liability company veil) that may be based upon, in respect of, arise under, out or by reason of, be connected with, or relate in any manner to: (a) this Agreement, the Ancillary Agreements or the Transactions, (b) the negotiation, execution or performance of this Agreement or any Ancillary Agreement (including any representation or warranty made in, in connection with, or as an inducement to, this Agreement or any Ancillary Agreement), (c) any breach of this Agreement or any Ancillary Agreement and (d) any failure of the Transactions to be consummated, may be made only against (and, without prejudice to the rights of any express third party beneficiary to whom rights under this Agreement inure pursuant to this Section 8.15), are those solely of the persons that are expressly identified as Parties to this Agreement (or, as applicable, the relevant Ancillary Agreement) and not against any Nonparty Affiliate (as defined below). Except in the case of fraud, no other person, including any director, officer, employee, incorporator, member, partner, manager, shareholder, optionholder, affiliate, agent, attorney or representative of, or any financial advisor or lender to, any Party (with respect to this Agreement) or any party to any Ancillary Agreement (with respect to such Ancillary Agreement), or any director, officer, employee, incorporator, member, partner, manager, shareholder, affiliate, agent, attorney or representative of, or any financial advisor or lender to (each of the foregoing, a “Nonparty Affiliate”) any of the foregoing, shall have any liabilities (whether in contract or in tort, in law or in equity, or granted by statute whether by or through attempted piercing of the corporate, limited partnership or limited liability company veil) for any claims, causes of action, obligations or liabilities arising under, out of, in connection with or related in any manner to the items in the immediately preceding clauses (a) through (d) and each Party, on behalf of itself and its affiliates, hereby irrevocably releases and forever discharges each of the Nonparty Affiliate from any such liability or obligation.
