Business Combination Agreement

As previously disclosed by TortoiseEcofin Acquisition Corp. III, a Cayman Islands exempted company (“TRTL”), in its Current Report on Form 8-K that was filed with the Securities and Exchange Commission (the “SEC”) on August 18, 2023, on August 14, 2023, TRTL, One Energy Enterprises Inc., a Delaware corporation (“One Energy”), and TRTL III Merger Sub Inc., a Delaware corporation and a wholly-owned subsidiary of TRTL, entered into a Business Combination Agreement (the “Original Business Combination Agreement”).

On February 14, 2024, TRTL and One Energy entered into an Amended and Restated Business Combination Agreement (the “Business Combination Agreement”) with TRTL Holding Corp., a Delaware corporation and wholly-owned subsidiary of TRTL (“Pubco”), TRTL III First Merger Sub Inc., a Delaware corporation and a wholly-owned subsidiary of Pubco (“TRTL Merger Sub”), OEE Merger Sub Inc., a Delaware corporation and a wholly-owned subsidiary of Pubco (“Company Merger Sub” and together with TRTL Merger Sub, the “Merger Subs”) (all of the transactions contemplated by the Business Combination Agreement, including the issuances of securities thereunder, the “Business Combination”). The Business Combination Agreement amended, restated and superseded the Original Business Combination Agreement.

Pursuant to the Business Combination Agreement, subject to the terms and conditions set forth therein, (i) at least one day prior to the Closing Date (as defined below), TRTL will transfer by way of continuation out of the Cayman Islands and into the State of Delaware to re-domicile and become a Delaware corporation (the “Domestication”), (ii) following the Domestication, TRTL Merger Sub will merge with and into TRTL, with TRTL continuing as the surviving entity and a wholly-owned subsidiary of Pubco (the “TRTL Merger”), in connection with which all of the existing securities of TRTL will be exchanged for rights to receive securities of Pubco as follows: (a) each share of TRTL common stock, par value $0.0001 per share (“TRTL Common Shares”), outstanding immediately prior to the effective time of the TRTL Merger shall automatically convert into one share of common stock, par value $0.0001 per share, issued by Pubco (“Pubco Common Shares”) and one contingent share right (“CSR”), entitling the holder to a contingent future right, subject to satisfaction of certain trading price-based conditions, to receive a portion of certain Pubco Common Shares otherwise deliverable at the closing of the transactions contemplated by the Business Combination Agreement (the “Closing”) to the founder and Chief Executive Officer of One Energy, as further described below (except with regard to holders of Class B ordinary shares of TRTL, par value $0.0001 per share (“TRTL Class B Ordinary Shares”), that have waived their rights to receive CSRs for their TRTL Class B Ordinary Shares or Class A ordinary shares of TRTL, par value $0.0001 per share (“TRTL Class A Ordinary Shares”), issued upon conversion of their TRTL Class B Ordinary Shares) and (b) each warrant to purchase TRTL Class A Ordinary Shares shall automatically convert into one warrant to purchase Pubco Common Shares (“Pubco Warrant”) on substantially the same terms and conditions; (iii) prior to the Company Merger, One Energy shall cause the holders of all of its issued and outstanding convertible instruments (other than the options to be assumed by Pubco in connection with the Business Combination) (“Company Convertible Securities”) to either exchange or convert all of their issued and outstanding Company Convertible Securities for shares of One Energy Common Stock (as defined below) (including any accrued or declared but unpaid dividends) at the applicable conversion ratio set forth in One Energy’s governing documents or the terms of the applicable instruments (the “Company Exchanges”); (iv) promptly following the Company Exchanges, Company Merger Sub will merge with and into One Energy, with One Energy continuing as the surviving entity and a wholly-owned subsidiary of Pubco (the “Company Merger”, and together with the TRTL Merger, the “Mergers”), pursuant to which, other than dissenting shares, if any, (a) all One Energy Common Stock issued and outstanding immediately prior to the effective time of the Company Merger (after giving effect to the Company Exchanges) will be cancelled and converted into the right to receive such number of Pubco Common Shares as shall be determined in accordance with an allocation schedule (the “Allocation Schedule”) to be delivered prior and as a condition to Closing pursuant to the terms of the Business Combination Agreement (all such shares, collectively, the “Aggregate Common Share Consideration”), and (b) all issued and outstanding shares of One Energy preferred stock, par value $0.0001 per share (“One Energy Preferred Shares”), if any such shares remain outstanding as of immediately prior to the effective time of the Company Merger (after giving effect to the Company Exchanges) will be canceled and converted into the right to receive one share of preferred stock of Pubco, par value $0.0001 per share (“Pubco Preferred Shares”), subject to the Allocation

Schedule, with substantially similar rights, preferences and privileges as each One Energy Preferred Share, provided, however, that Pubco Preferred Shares shall convert into Pubco Common Shares after applying the conversion ratio determined in accordance with the terms of the Business Combination Agreement (all such shares, if any, collectively, the “Aggregate Preferred Share Consideration”); and (v) all of the options to purchase One Energy shares (“Company Options”), whether vested or unvested, issued and outstanding as of immediately prior to the effective time of the Company Merger will be assumed by Pubco and, in the case of unvested Company Options, accelerate in full and become options to purchase Pubco Common Shares (the “Assumed Options”), subject to adjustments to the number and exercise prices thereof in accordance with the terms of the Business Combination Agreement and as set forth in the Allocation Schedule.

Additionally, at least one day prior to the Closing Date, (i) TRTL shall have caused the Domestication to have occurred and, in connection therewith, shall have caused each TRTL Class B Ordinary Share that is issued and outstanding as of such date to be converted, on a one- for-one basis, into one TRTL Class A Ordinary Share and (ii) One Energy shall have caused each share of One Energy Class B common stock, par value $0.0001 per share (“One Energy Class B Common Stock”) that is issued and outstanding as of such date to be converted, on a one-for-one basis, into one share of One Energy Class A common stock, par value $0.0001 per share (“One Energy Class A Common Stock”, and together with the One Energy Class B Common Stock, the “One Energy Common Stock”).

Pursuant to the terms of the Business Combination Agreement, the total consideration to be delivered to security holders of One Energy (“One Energy Securityholders”), inclusive of Assumed Options, will have an aggregate value equal to the sum of (i) $300,000,000 minus the amount of certain of One Energy’s indebtedness as of immediately prior to the Closing and (ii) the aggregate amount of the exercise prices of all Company Options that are outstanding and in-the-money (as defined in the Business Combination Agreement) as of immediately prior to the effective date of the Company Merger, assuming no cashless exercises of Company Options prior to such date (the “Adjusted Equity Value”), with each holder of One Energy Common Stock (treating shares of One Energy Preferred Stock on an as-converted to One Energy Common Stock basis but excluding share held as treasury stock) receiving a number of Pubco Common Shares equal to a conversion ratio to be determined at Closing in accordance with the terms of the Business Combination Agreement and the Allocation Schedule delivered thereunder, based on a deemed value per Pubco Common Share of $10.00 per share.

At the Closing, one half of the total number of Pubco Common Shares otherwise deliverable at the Closing to Jereme Kent, the Chief Executive Officer of One Energy, will be deposited into an escrow account (the “CSR Escrow Account”) to be distributed to the holders of CSRs in accordance with the terms of a Contingent Stock Rights Agreement (“CSR Agreement”) to be entered into prior to or in connection with the Closing in the event that the post-Closing trading price of Pubco Common Shares does not equal or exceed a daily VWAP of $12.00 per share over 20 out of any 30 consecutive trading days, during the two-year period after the Closing.

In addition to the Aggregate Common Share Consideration, Aggregate Preferred Share Consideration and Aggregate Options deliverable at the closing of the Business Combination (the “Closing”), One Energy stockholders as of the closing date (the “Closing Date”) of the Mergers (the “One Energy Stockholders”) will have the contingent right to receive up to 5,000,000 additional Pubco Common Shares (the “Company Earnout Shares”) if the following conditions occur during the period commencing on the date that is 90 days after the Closing Date and ending on the 5-year anniversary of the Closing Date (the “Company Earnout Period”):

i. if the volume weighted average trading price (“VWAP”) of Pubco Common Shares is greater than $12.50 for any twenty (20) trading days out of any thirty (30) consecutive trading days ending on the trading day immediately prior to the date of determination, 2,500,000 Pubco Common Shares shall be issued to the One Energy Stockholders; and

ii. if VWAP of Pubco Common Shares is greater than $15.00 for any twenty (20) trading days out of any thirty (30) consecutive trading days ending on the trading day immediately prior to the date of determination, 2,500,000 Pubco Common Shares shall be issued to the One Energy Stockholders.

Additionally, if, during the Company Earnout Period there is a change of control transaction in which Pubco or its stockholders have the right to receive consideration implying a value per share (as agreed in good faith by the Pubco Board) that is greater than or equal to the applicable VWAP in the triggering events specified above, any applicable Company Earnout Shares that have not previously been issued will be issued to the One Energy Stockholders.

Additionally, TortoiseEcofin Sponsor III LLC, a Cayman Islands limited liability company (the “Sponsor”), has agreed, contingent upon the Closing, to subject 1,750,000 Pubco Common Shares to be issued to the Sponsor in the TRTL Merger (“Sponsor Earnout Shares”) to contingent forfeiture (the “Sponsor Earnout Terms”) during the two-year period commencing on the date immediately following the Closing Date and ending on and including the date of the two year anniversary of the Closing Date (the “Sponsor Earnout Period”), unless the VWAP of Pubco Common Shares is equal to or greater than $12.00 for any twenty (20) trading days out of any thirty (30) consecutive trading days ending on the trading day immediately prior to the date of determination within the Sponsor Earnout Period (the “Sponsor Triggering Event”). If, during the Sponsor Earnout Period, there is a change of control transaction in which Pubco or its stockholders have the right to receive consideration implying a value per Pubco Common Share (as agreed in good faith the Pubco Board, together with those individuals who are or were, prior to the Closing, both members of the Sponsor and officers of Pubco (as of the date of the Business Combination Agreement) and hold not less than a majority of the total number of Sponsor Earnout Shares as of the applicable determination date) that is greater than or equal to the VWAP for Pubco Common Shares in the Sponsor Trigger Event, any undistributed Sponsor Earnout Shares will cease to be subject to forfeiture.

Governing Law

Many factors could cause actual future events to differ materially from the forward-looking statements in this report, including, without limitation: (i) the risk that the Business Combination may not be completed in a timely manner or at all, which may adversely affect the price of TRTL’s securities, (ii) the risk that the Business Combination may not be completed by TRTL’s business combination deadline and the potential failure to obtain an extension of the business combination deadline if sought by TRTL, (iii) the failure to satisfy the conditions to the consummation of the Business Combination, including the requirements that the Business Combination Agreement and the transactions contemplated thereby be approved by the shareholders of TRTL and by the stockholders of One Energy, respectively, (iv) the failure to obtain regulatory approvals and any other third party consents, as applicable, as may be required to consummate the Business Combination, (v) the occurrence of any event, change or other circumstance that could give rise to the termination of the Business Combination Agreement, or that redemptions by TRTL public shareholders may exceed expectations, (vi) the effect of the announcement or pendency of the Business Combination on One Energy’s business relationships, operating results, and business generally, (vii) risks that the Business Combination disrupts current plans and operations of One Energy, (viii) the outcome of any legal proceedings that may be instituted against One Energy or against TRTL related to the Business Combination Agreement or the Business Combination, (ix) the ability to maintain the listing of TRTL’s securities on New York Stock Exchange, (x) changes in the competitive market in which One Energy operates, variations in performance across competitors, changes in laws and regulations affecting One Energy’s business and changes in the capital structure of Pubco after the Closing, (xi) the ability to implement business plans, growth, marketplace, customer pipeline and other expectations after the completion of the Business Combination, and identify and realize additional opportunities, (xii) the potential inability of One Energy to achieve its business and growth plans, (xiii) the ability of One Energy to enforce its current material contracts or to secure long-term or other committed contracts with new or existing customers on terms favorable to One Energy, (xiv) the risk that One Energy will need to raise additional capital to execute its business plans, which may not be available on acceptable terms or at all, (xv) the risk that One Energy experiences difficulties in managing its growth and expanding operations, (xvi) the risk of One Energy’s cyber security measures being unable to prevent hacking or disruption to

One Energy’s customers, and (xvii) the risk of economic downturn, increased competition, a changing of energy regulatory landscape and related impacts that could occur in the highly competitive energy market, including, among other things, that One Energy will not meet milestones for funding its ongoing and future project pipeline. The foregoing list of factors is not exhaustive. Recipients should carefully consider such factors and the other risks and uncertainties described and to be described in the “Risk Factors” section of TRTL’s initial public offering prospectus filed with the SEC on July 21, 2021, TRTL’s Annual Report on Form 10-K for the year ended December 31, 2021, as filed with the SEC on March 24, 2022, TRTL’s Annual Report on Form 10-K for the year ended December 31, 2022, as filed with the SEC on March 22, 2023, and subsequent periodic reports filed by TRTL with the SEC, the Registration Statement to be filed by Pubco in connection with the Business Combination and other documents filed or to be filed by TRTL or Pubco from time to time with the SEC. These filings identify and address other important risks and uncertainties that could cause actual events and results to differ materially from those contained in the forward-looking statements. Forward-looking statements speak only as of the date they are made. Recipients are cautioned not to put undue reliance on forward-looking statements, and neither One Energy nor TRTL assume any obligation to, nor intend to, update or revise these forward-looking statements, whether as a result of new information, future events, or otherwise, except as required by law. Neither One Energy nor TRTL gives any assurance that either One Energy or TRTL, or Pubco, will achieve its expectations.

Loan and Transfer Agreement

On February 15, 2024, TRTL entered into loan and transfer agreements (the “Loan and Transfer Agreements”) between TRTL, the Sponsor, One Energy and other parties (the “February Lenders”), pursuant to which the February Lenders agreed to loan an aggregate of $333,000 to the Sponsor (the “February Loan”) and the Sponsor intends to loan such amount to TRTL (the “SPAC Loan”). Neither the February Loan nor the SPAC Loan will accrue any interest.

The Sponsor and TRTL are jointly responsible for the payment of the principal amount of the February Loan within five business days of the completion of the Business Combination. In addition, within five business days of the completion of the Business Combination, One Energy will pay the February Lenders an additional one-time cash payment in the aggregate amount of $166,500. In addition, in the event the Business Combination is completed and a mandatory trigger of One Energy’s Series A preferred stock occurs, the February Lenders will have a one-time option to cause Pubco to repurchase up to an aggregate of 120,000 shares of One Energy Class A Common Stock, on an as-converted basis, owned by the February Lenders at $10.00 per share, which option is exercisable within the first thirty trading days following the completion of the Business Combination.

If the Business Combination is not completed, One Energy will issue to each February Lender the number of shares of its common stock equal to the principal amount of its February Loan at a price that values One Energy at its most recent private company equity valuation. If One Energy’s shares of common stock are not listed on a national securities exchange by December 31, 2026, each February Lender will also have a one-time option to cause One Energy to redeem all of its owned shares resulting from the Loan and Transfer Agreement for an amount equal to the product of (x) 1.05 and (y) each February Lender’s pro rata amount of the February Loan.

As additional consideration for the February Lenders making the February Loan available to the Sponsor, the Sponsor agreed to transfer to the February Lenders an aggregate of 166,500 TRTL Class B Ordinary Shares upon the closing of the Business Combination.

The foregoing description is qualified in its entirety by reference to the terms and conditions of the Loan and Transfer Agreement, the form of which is attached as Exhibit 10.1 hereto and is incorporated herein by reference.

(b) At least three (3) Business Days prior to the Closing Date, the Company shall mail or otherwise deliver, or shall cause to be mailed or otherwise delivered, to the Company Shareholders a letter of transmittal in a form reasonably acceptable to TortoiseCorp III, and the Company (the “Letter of Transmittal”).

33

(c) At the Effective Time, TortoiseCorp III shall deposit, or cause to be deposited, with the Exchange Agent, for the benefit of the Company Shareholders and for exchange in accordance with this Section 2.4 through the Exchange Agent, evidence of Pubco Shares in book-entry form representing the portion of the Transaction Share Consideration issuable pursuant to Section 2.1(f)(vii) in exchange for the Company Shares outstanding immediately prior to the Effective Time. All shares in book-entry form representing the portion of the Transaction Share Consideration issuable pursuant to Section 2.1(f)(vii) deposited with the Exchange Agent shall be referred to in this Agreement as the “Exchange Fund”.

(d) Each Company Shareholder whose Company Shares have been converted into the right to receive a portion of the Transaction Share Consideration pursuant to Section 2.1(f)(vii) shall be entitled to receive the portion of the Transaction Share Consideration to which he, she or it is entitled on the Closing Date upon (i) surrender of a Certificate (or affidavit of loss in lieu thereof in the form required by the Letter of Transmittal), together with the delivery of a properly completed and duly executed Letter of Transmittal (including, for the avoidance of doubt, any documents or agreements required by the Letter of Transmittal), to the Exchange Agent or (ii) in the case of Company Shares held in book-entry form, a properly completed and duly executed Letter of Transmittal (including, for the avoidance of doubt, any documents or agreements required by the Letter of Transmittal), to the Exchange Agent.

(e) If a properly completed and duly executed Letter of Transmittal, together with any Company Certificates (or affidavit of loss in lieu thereof in the form required by the Letter of Transmittal), if any, is delivered to the Exchange Agent in accordance with Section 2.4(d) (i) at least one Business Day prior to the Closing Date, then TortoiseCorp III and the Company shall take all necessary actions to cause the applicable portion of the Transaction Share Consideration to be issued to the applicable Company Shareholder in book-entry form on the Closing Date or (ii) less than one Business Day prior to the Closing Date, then TortoiseCorp III and the Company (or the Company Surviving Subsidiary) shall take all necessary actions to cause the applicable portion of the Transaction Share Consideration to be issued to the Company Shareholder in book-entry form within two (2) Business Days after such delivery.

(f) If any portion of the Transaction Share Consideration or any other Pubco Shares are to be issued in a name other than that in which the Company Certificates or TortoiseCorp III Certificates surrendered (or transferred in book entry form) in exchange therefor are registered, it shall be a condition to the issuance of the applicable portion of the Transaction Share Consideration or other such other Pubco Shares that (i) either such Company Certificate or TortoiseCorp III Certificate shall be properly endorsed or shall otherwise be in proper form for transfer or such Company Share or TortoiseCorp III Share in book-entry form shall be properly transferred and (ii) the Person requesting such consideration pay to the Exchange Agent any transfer Taxes required as a result of such consideration being issued to a Person other than the registered holder of such Company Certificate or TortoiseCorp III Certificate, or Company Share or TortoiseCorp III Share, as applicable, in book-entry form or establish to the satisfaction of the Exchange Agent that such transfer Taxes have been paid or are not payable.

34

(g) No interest will be paid or accrued on the Transaction Share Consideration (or any portion thereof). From and after the Company Merger Effective Time, until surrendered or transferred, as applicable, in accordance with this Section 2.4, each Company Share (other than, for the avoidance of doubt, the Company Shares cancelled and extinguished pursuant to Section 2.1(f)(viii)) shall solely represent the right to receive a portion of the Transaction Share Consideration to which such Company Share is entitled to receive pursuant to Section 2.1(f)(vii).

(h) At the Effective Time, the stock transfer books of the Company shall be closed and there shall be no transfers of Company Shares that were outstanding immediately prior to the Effective Time.

(i) Any portion of the Exchange Fund that remains unclaimed by the Company Shareholders twelve (12) months following the Closing Date shall be delivered to Pubco or as otherwise instructed by Pubco, and any Company Shareholder who has not exchanged his, her or its Company Shares for the applicable portion of the Transaction Share Consideration in accordance with this Section 2.4 prior to that time shall thereafter look only to Pubco for the issuance of the applicable portion of the Transaction Share Consideration, without any interest thereon. None of Pubco, the Company Surviving Subsidiary or any of their respective Affiliates shall be liable to any Person in respect of any consideration delivered to a public official pursuant to any applicable abandoned property, unclaimed property, escheat, or similar Law. Any portion of the Transaction Share Consideration remaining unclaimed by the Company Shareholders immediately prior to such time when the amounts would otherwise escheat to or become property of any Governmental Entity shall become, to the extent permitted by applicable Law, the property of Pubco free and clear of any claims or interest of any Person previously entitled thereto.

Section 2.5 Withholding. Pubco, TortoiseCorp III, the Merger Subs, the Group Companies and the Exchange Agent (and each of their respective Affiliates, agents and representatives) shall be entitled to deduct and withhold (or cause to be deducted and withheld) from any amounts payable pursuant to this Agreement such amounts as are required to be deducted and withheld under applicable Law. To the extent that amounts are so deducted and withheld and timely remitted to the applicable Governmental Entity, such deducted and withheld amounts shall be treated for all purposes of this Agreement as having been paid to the Person in respect of which such deduction and withholding was made. The Parties shall cooperate in good faith to eliminate or reduce any such deduction or withholding (including through the request and provision of any statements, forms or other documents to reduce or eliminate any such deduction or withholding).

Section 2.6 Issuance of Company Earnout Shares.

(a) Within three (3) Business Days after the occurrence of a Company Triggering Event, Pubco shall issue or cause to be issued to the Company Shareholders the following number of Pubco Common Shares (as adjusted for share subdivisions, share capitalizations, reorganizations, recapitalizations and the like) as set forth on the Allocation Schedule (such issued Pubco Common Shares, collectively, the “Company Earnout Shares”):

35

(i) Upon the occurrence of Company Triggering Event I, a one-time issuance of 2,500,000 Company Earnout Shares; and

(ii) Upon the occurrence of Company Triggering Event II, a one-time issuance of 2,500,000 Company Earnout Shares.

(b) In the event there is a Company Sale during the Company Earnout Period pursuant to which Pubco or its stockholders have the right to receive consideration implying a value per Pubco Common Share (as agreed in good faith by the Pubco Board) that is greater than or equal to the applicable Pubco VWAP specified in Company Triggering Event I or Company Triggering Event II, any Company Earnout Shares that have not previously issued in accordance with Section 2.6(a)(i) or Section 2.6(a)(ii), as applicable, shall be issued immediately prior to the closing of such Company Sale, and the Company Shareholders shall be eligible to participate in such Company Sale with respect to the Company Earnout Shares deemed issued pursuant to this Section 2.6(b) on the same terms, and subject to the same conditions, as apply to the holders of Pubco Common Shares generally. Upon the consummation of a Company Sale, the Company Earnout Period shall terminate and the Company Shareholders shall have no further right to receive or earn the Company Earnout Shares other than in accordance with this Section 2.6(b) with respect to such Company Sale.

(c) Any issuance of Company Earnout Shares is intended to be treated as an adjustment to the consideration paid in the Company Merger that is subject to Section 354 of the Code (or any comparable or similar provisions of applicable state or local Law), except to the extent otherwise required by applicable Law (including, for the avoidance of doubt, with respect to any amounts required to be treated as interest pursuant to Section 483 of the Code).

(d) When issued, the Company Earnout Shares will be duly authorized, validly issued, fully paid and non-assessable, will not be issued in violation of the Governing Documents of Pubco or any other Contract to which Pubco is party or bound, will not be issued in violation of any preemptive rights, call option, right of first refusal or first offer, subscription rights, transfer restrictions or similar rights of any Person and will have been offered, sold and issued in compliance with applicable Law, including Securities Laws. To the extent not otherwise required by Law, such Company Earnout Shares will be issued through the facilities of the Depository Trust Company, without bearing any restrictive legend thereon; provided, that if the Pubco Common Shares issued as Transaction Share Consideration are still subject to restrictions on transfer as of the date such Company Earnout Shares are issued, such restrictions on transfer shall also be applicable to the Company Earnout Shares.

Section 2.7 CSR Escrow. At or prior to the Closing, Pubco, Jereme Kent, and Continental Stock Transfer & Trust Company (or such other escrow agent mutually acceptable to TortoiseCorp III and the Company), as escrow agent (the “CSR Escrow Agent”), shall enter into an escrow agreement, effective as of the Effective Time, in form and substance reasonably satisfactory to TortoiseCorp III and Jereme Kent (the “CSR Escrow Agreement”), pursuant to which Pubco shall deposit with the CSR Escrow Agent the Kent CSR Shares (the “CSR Escrow Shares”) to be held in a segregated escrow account (the “CSR Escrow Account”) and disbursed in accordance with the terms of the Contingent Stock Rights Agreement and the CSR Escrow Agreement. For the avoidance of doubt, dividends or distributions, if any, shall accumulate in the CSR Escrow Account for so long as any CSR Escrow Shares are held within the CSR Escrow Account.

36

Section 2.8 Sponsor Earnout Shares.

(a) General. The Sponsor has agreed that, effective upon the Closing, the Sponsor will subject 1,750,000 Pubco Common Shares owned by Sponsor (the “Sponsor Earnout Shares”) to forfeiture if the Sponsor Triggering Event does not occur during the Sponsor Earnout Period, with such Sponsor Earnout Shares vesting (and therefore no longer subject to forfeiture) pursuant to the terms of this Section 2.8. Until the occurrence of the Sponsor Triggering Event, certificates or book entry statements representing the Sponsor Earnout Shares shall bear a legend referencing that they are subject to forfeiture pursuant to the provisions of this Agreement; provided, however, that upon the vesting of any Sponsor Earnout Shares in accordance with the terms herein, Pubco shall immediately cause the removal of such legend.

(b) Vesting.

(i) The Sponsor Earnout Shares shall immediately become fully vested and no longer subject to forfeiture upon the occurrence of the Sponsor Triggering Event.

(ii) In the event there is a Company Sale during the Sponsor Earnout Period pursuant to which Pubco or its stockholders have the right to receive consideration implying a value per Pubco Common Share (as agreed in good faith by those individuals who are (or were) both members of the Sponsor and officers of Pubco (in each case determined as of the date hereof) and hold not less than a majority of the Sponsor Earnout Shares and the Pubco Board) that is greater than or equal to the Pubco VWAP specified in the Sponsor Triggering Event, then the Sponsor Triggering Event shall be deemed to have occurred.

(c) Adjustment. If, and as often as, the outstanding Pubco Common Shares are changed into a different number of shares or a different class, by reason of any dividend, subdivision, reclassification, recapitalization, split, combination or exchange, or any similar event after the date hereof, then the number of Sponsor Earnout Shares to be surrendered pursuant to this Section 2.8 and the Pubco VWAP specified with respect to the Sponsor Triggering Event will, in each case, be equitably adjusted to reflect such change.

Section 2.9 Appraisal and Dissenters’ Rights. Notwithstanding any provision of this Agreement to the contrary and to the extent available under the DGCL, Company Shares that are issued and outstanding immediately prior to the Effective Time and which are held by a Company Shareholder who did not vote in favor of the Company Merger (or consent thereto in writing) and who is entitled to demand and properly demands appraisal of such shares (the “Dissenting Shares”) pursuant to, and who complies in all respects with, the provisions of Section 262 of the DGCL (the “Dissenting Shareholders”) shall not be converted into or be exchangeable for the right to receive such Dissenting Shareholder’s portion of the Transaction Share Consideration pursuant to Section 2.1(f)(vii), but instead such holder shall be entitled to receive such consideration as may be determined to be due to such Dissenting Shareholder pursuant to Section 262 of the DGCL (and at the Effective Time, such Dissenting Shares shall no

37

longer be outstanding and shall automatically be cancelled and shall cease to exist, and such holder shall cease to have any rights with respect thereto, except the rights set forth in Section 262 of the DGCL), unless and until such holder shall have failed to perfect or shall have effectively withdrawn or lost its right to appraisal under the DGCL. If any Dissenting Shareholder shall have failed to perfect or shall have effectively withdrawn or lost such right, each of such holder’s Company Shares shall thereupon be treated as if they had been converted into and become exchangeable for the right to receive, as of the Effective Time, the applicable portion of the Transaction Share Consideration pursuant to Section 2.1(f)(vii), without interest. The Company shall give Pubco prompt notice and a copy of any written demands for appraisal, attempted withdrawals of such demands, and any other instruments served pursuant to applicable Law that are received by the Company relating to Company Shareholders’ rights of appraisal. The Company shall not, except with the prior written consent of Pubco, voluntarily make any payment with respect to any demands for appraisal, offer to settle or settle any such demands or approve any withdrawal of any such demands.

period of six (6) years and (ii) Pubco will perform and discharge, or cause to be performed and discharged, all obligations to provide such indemnity and exculpation during such six (6)-year period. To the maximum extent permitted by applicable Law, during such six (6)-year period, Pubco shall advance, or caused to be advanced, expenses in connection with such indemnification as provided in the applicable TortoiseCorp III Party’s Governing Documents or other applicable agreements as in effect immediately prior to the Effective Time. The indemnification and liability limitation or exculpation provisions of Pubco’s Governing Documents shall not, during such six (6)-year period, be amended, repealed or otherwise modified after the Effective Time in any manner that would materially and adversely affect the rights thereunder of individuals who, as of immediately prior to the Effective Time, or at any time prior to such time, were directors or officers of any TortoiseCorp III Party (the “TortoiseCorp III D&O Persons”) entitled to be so indemnified, have their liability limited or be exculpated with respect to any matters occurring on or prior to the Effective Time and relating to the fact that such TortoiseCorp III D&O Person was a director or officer of any TortoiseCorp III Party immediately prior to the Effective Time, unless such amendment, repeal or other modification is required by applicable Law.

(b) TortoiseCorp III shall not have any obligation under this Section 5.14 to any TortoiseCorp III D&O Person when and if a court of competent jurisdiction shall ultimately determine (and such determination shall have become final and non-appealable) that the indemnification of such TortoiseCorp III D&O Person in the manner contemplated hereby is prohibited by applicable Law.

(c) For a period of six (6) years after the Effective Time, Pubco shall maintain, without any lapses in coverage, directors’ and officers’ liability insurance for the benefit of those Persons who are currently covered by any comparable insurance policies of the TortoiseCorp III Parties as of the date of this Agreement with respect to matters occurring on or prior to the Effective Time. Such insurance policies shall provide coverage on terms (with respect to coverage and amount) that are substantially the same as (and no less favorable in the aggregate to the insured than) the coverage provided under TortoiseCorp III’s directors’ and officers’ liability insurance policies as of the date of this Agreement. Alternatively, TortoiseCorp III may purchase, at or prior to the Closing, and Pubco shall maintain, or cause to be maintained, in effect for a period of six (6) years after the Effective Time, without lapses in coverage, an extended reporting period or tail insurance policy that affords coverage which is no less favorable in the aggregate to the insured than the coverage provided under TortoiseCorp III’s directors’ and officers’ liability insurance policies as of the date of this Agreement. In either event, Pubco shall not be obligated to pay annual premiums in excess of three hundred percent (300%) of the most recent annual premium paid by TortoiseCorp III prior to the date of this Agreement and, in such event, Pubco shall purchase the maximum coverage available for three hundred percent (300%) of the most recent annual premium paid by TortoiseCorp III prior to the date of this Agreement.

(d) If Pubco or any of its successors or assigns (i) shall merge or consolidate with or merge into any other corporation or entity and shall not be the surviving or continuing corporation or entity of such consolidation or merger or (ii) shall transfer all or substantially all of their respective properties and assets as an entity in one or a series of related transactions to any Person, then in each such case, proper provisions shall be made so that the successors or assigns of Pubco shall assume all of the obligations set forth in this Section 5.14.

88

(e) The TortoiseCorp III D&O Persons entitled to the indemnification, liability limitation, exculpation and insurance set forth in this Section 5.14 are intended to be third-party beneficiaries of this Section 5.14. This Section 5.14 shall survive the consummation of the transactions contemplated by this Agreement and shall be binding on all successors and assigns of Pubco.

Section 5.15 Company Indemnification; Directors’ and Officers’ Insurance.

(a) Each Party agrees that (i) all rights to indemnification or exculpation now existing in favor of the directors and officers of the Group Companies, as provided in the Group Companies’ Governing Documents or otherwise in effect as of immediately prior to the Effective Time, in either case, solely with respect to any matters occurring on or prior to the Effective Time, shall survive the transactions contemplated by this Agreement and shall continue in full force and effect from and after the Effective Time for a period of six (6) years and (ii) Pubco will cause the applicable Group Companies to perform and discharge all obligations to provide such indemnity and exculpation during such six (6)-year period. To the maximum extent permitted by applicable Law, during such six (6)-year period, Pubco shall cause the applicable Group Companies to advance expenses in connection with such indemnification as provided in the Group Companies’ Governing Documents or other applicable agreements in effect as of immediately prior to the Effective Time. The indemnification and liability limitation or exculpation provisions of the Group Companies’ Governing Documents shall not, during such six (6)-year period, be amended, repealed or otherwise modified after the Effective Time in any manner that would materially and adversely affect the rights thereunder of individuals who, as of the Effective Time or at any time prior to the Effective Time, were directors or officers of the Group Companies (the “Company D&O Persons”) entitled to be so indemnified, have their liability limited or be exculpated with respect to any matters occurring prior to Closing and relating to the fact that such Company D&O Person was a director or officer of any Group Company prior to the Effective Time, unless such amendment, repeal or other modification is required by applicable Law.

(b) None of Pubco, TortoiseCorp III or the Group Companies shall have any obligation under this Section 5.15 to any Company D&O Person when and if a court of competent jurisdiction shall ultimately determine (and such determination shall have become final and non-appealable) that the indemnification of such Company D&O Person in the manner contemplated hereby is prohibited by applicable Law.

(c) The Company, Pubco and TortoiseCorp III shall use commercially reasonable efforts to ensure that the directors’ and officers’ liability insurance of Pubco from and after the Closing will provide directors’ and officers’ liability insurance coverage for the benefit of those Persons who are currently covered by any comparable insurance policies of the Group Companies as of the date of this Agreement with respect to matters occurring on or prior to the Effective Time. If Pubco is unable to secure such coverage under its directors’ and officers’ liability insurance then the Company may purchase, at or prior to the Closing, and Pubco shall maintain, or cause to be maintained, in effect for a period of six (6) years after the Effective Time, without lapses in coverage, a “tail” policy providing directors’ and officers’ liability

89

insurance coverage for the benefit of those Persons who are currently covered by any comparable insurance policies of the Group Companies as of the date of this Agreement with respect to matters occurring on or prior to the Effective Time (the “Company D&O Tail Policy”). Such “tail” policy shall provide coverage on terms (with respect to coverage and amount) that are substantially the same as (and no less favorable in the aggregate to the insured than) the coverage provided under the Group Companies’ directors’ and officers’ liability insurance policies as of the date of this Agreement; provided that none of the Company, TortoiseCorp III, Pubco or any of their respective Affiliates shall pay a premium for such “tail” policy in excess of three hundred percent (300%) of the most recent annual premium paid by the Group Companies prior to the date of this Agreement and, in such event, the Company, TortoiseCorp III, Pubco or one of their respective Affiliates shall purchase the maximum coverage available for three hundred percent (300%) of the most recent annual premium paid by the Group Companies prior to the date of this Agreement.

(d) If Pubco or any of its successors or assigns (i) shall merge or consolidate with or merge into any other corporation or entity and shall not be the surviving or continuing corporation or entity of such consolidation or merger or (ii) shall transfer all or substantially all of their respective properties and assets as an entity in one or a series of related transactions to any Person, then in each such case, proper provisions shall be made so that the successors or assigns of Pubco shall assume all of the obligations set forth in this Section 5.15.

(e) The Company D&O Persons entitled to the indemnification, liability limitation, exculpation and insurance set forth in this Section 5.15 are intended to be third-party beneficiaries of this Section 5.15. This Section 5.15 shall survive the consummation of the transactions contemplated by this Agreement and shall be binding on all successors and assigns of Pubco.

Section 5.16 Post-Closing Directors and Officers.

(a) Pubco shall take all such action within its power as may be necessary or appropriate such that effective immediately after the Effective Time, the Pubco Board will consist of seven (7) directors: (two) persons that are designated by TortoiseCorp III prior to the Closing; five (5) persons designated by the Company prior to the Closing, at least four (4) of whom shall be required to qualify as an independent director under the NYSE rules; provided that the applicable Party shall only designate Person(s) eligible to serve as a director on the Pubco Board in accordance with the applicable corporate governance standards and qualifications set forth by NYSE and any SEC rules, regulations or provisions related to individuals serving on the board of directors of a public company.

(b) The individual serving as the chief executive officer of the Company immediately after the Closing will be the same individual (in the same office) as that of the Company immediately prior to the Closing. In the event that such chief executive officer is unwilling or unable (whether due to death, disability, termination of service or otherwise) to serve as the chief executive officer, then, prior to the mailing of the Registration Statement/Proxy Statement to the Pre-Closing TortoiseCorp III Holders, Tortoise Corp III and the Company may designate another individual to replace such individual to serve as such chief executive officer. The Company may appoint additional qualified persons to serve as officers in other capacities immediately prior to Closing and, in which case, such additional officers shall be the same individuals (and in the same office) immediately following the Closing.

Section 8.17 Remedies. Except as otherwise expressly provided herein, any and all remedies provided herein will be deemed cumulative with and not exclusive of any other remedy conferred hereby, or by law or equity upon such Party, and the exercise by a Party of any one remedy will not preclude the exercise of any other remedy. 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 respective obligations under the provisions of this Agreement (including failing to take such actions as are required of them hereunder to consummate the transactions contemplated by this Agreement) in accordance with their specific terms or otherwise breach such provisions. It is accordingly agreed that the Parties shall be entitled to seek an injunction or injunctions, specific performance and other equitable relief to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement, in each case, without posting a bond or undertaking and without proof of damages and this being in addition to any other remedy to which they are entitled at law or in equity. Each of the Parties agrees that it will not oppose the granting of an injunction, specific performance and other equitable relief when expressly available pursuant to the terms of this Agreement on the basis that the other parties have an adequate remedy at law or an award of specific performance is not an appropriate remedy for any reason at law or equity.

Section 8.18 Trust Account Waiver. Reference is made to the final prospectus of TortoiseCorp III, filed with the SEC (File No. 333-253586) on July 19, 2021 (the “Prospectus”). The Company acknowledges and agrees and understands that TortoiseCorp III has established a trust account (the “Trust Account”) containing the proceeds of its initial public offering and from certain private placements occurring simultaneously with such initial public offering (including interest accrued from time to time thereon) for the benefit of TortoiseCorp III’s public shareholders (including overallotment shares acquired by TortoiseCorp III’s underwriters, the “Public Shareholders”), and TortoiseCorp III may disburse monies from the Trust Account only in the express circumstances described in the Prospectus. For and in consideration of TortoiseCorp III entering into this Agreement, and for other good and valuable consideration, the

105

receipt and sufficiency of which is hereby acknowledged, the Company hereby agrees on behalf of itself and its Representatives that, notwithstanding the foregoing or anything to the contrary in this Agreement, none of the Company nor any of its Representatives does 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 TortoiseCorp III or any of its Representatives, on the one hand, and the Company or any of its Representatives, 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 “Trust Account Released Claims”). The Company, on its own behalf and on behalf of its Representatives, hereby irrevocably waives any Trust Account Released Claims that it or any of its Representatives 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, or Contracts with TortoiseCorp III or its Representatives and will not seek recourse against the Trust Account (including any distributions therefrom) for any reason whatsoever (including for an alleged breach of any agreement with TortoiseCorp III or its Affiliates).
