3. CAPITALIZATION 
 3.1
Required Investments in the Company. 
 (a) BNGP. BNGP will make, and certain of its Affiliates have and will make on its
behalf, investments in the Company in the amounts and manner, and at the times, specified in Exhibit A. 
 (b)
B&WMR. B&WMR will make, and certain of its Affiliates have and will make on its behalf, investments in the Company in the amounts and manner, and at the times, specified in Exhibit B. 

(c) New Members. Each New Member may be required to make an investment in the Company in connection with its admission as a Member of
the Company in accordance with Section 9.2 and its Subscription Agreement. The investment (including any Capital Contributions) will be as agreed between B&WMR and the New Member and set forth in its Subscription Agreement.
Contemporaneously with any initial Capital Contributions by the New Member, the Company will distribute an amount equal to that Capital Contribution to B&WMR in accordance with Section 4.3(a). 

(d) Compromises. The prior written consent of BNGP and B&WMR is the only consent required with respect to any adjustment,
modification, amendment or other compromise of the Capital Contributions that is or was to be made under Section 3.1(a) or Section 3.1(b). The prior written consent of B&WMR is the only consent required with respect to
any adjustment, modification, amendment or other compromise of any Capital Contributions made by New Members under Section 3.1(c). 

3.2 Additional Capital Contributions. 

(a) Except as required under Section 3.1 or as a Member may agree in accordance with Section 3.2(b), no Member will be
required to make any additional Capital Contributions to the Company. 
 (b) In addition to investments required under
Section 3.1, the Board may determine from time to time that additional working capital is required and may cause the Company to request the Members to make additional Capital Contributions. In each case, the Company will first submit a
written notice to each Member identifying the due date, the aggregate amount and the payment terms of the requested Capital Contribution (a “Capital  

  
 3 








 
Call”). Each Member will have the right to invest its Share of the Capital Call (subject to increase for over subscription if some Members do not fully exercise their rights) on terms
and conditions contained in the Capital Call. Not more than 10 Business Days after a Capital Call, each Member will notify the Company in writing (i) whether the member will contribute its Share of the Capital Call, and (ii) the maximum
amount the Member would invest, if any, in excess of its Share (if one or more other Members do not participate in the Capital Call). If any Member does not invest its Share, then each Member who has elected to invest in excess of its Share (an
“Oversubscription Member”) will have the right to invest an additional amount, up to the amount which the other Members elected not to invest, which additional investment will be allocated pro rata (in proportion to their Share)
among all Oversubscription Members as required. No Member can be required to invest more than the amount it has specified. Members that participate in the Capital Call in an amount equal to their Share will maintain their Share after the Capital
Call. Oversubscription Members will increase their Share based on the amount so oversubscribed and, subject to Section 3.2(c), Members that do not participate in the Capital Call will have their Share decreased. 

(c) If a Capital Call occurs prior to the completion of the First Tranche Investment, then (i) in no event will BNGP’s Share be
decreased if BNGP elects in its sole discretion not to participate in the Capital Call and (ii) the amount invested by BNGP in connection with the Capital Call up to its Share will count as a payment towards BNGP’s First Tranche
Investment, unless otherwise agreed by BNGP and B&WMR. BNGP’s Share will be increased in accordance with Section 3.2(d) in connection with a Capital Call that occurs prior to completion of the First Tranche Investment only if
BNGP invests an amount in excess of its Share, in which case any amount invested in excess of its Share will not be counted as payments towards BNGP’s First Tranche Investment. 

(d) The amount of the required increase or decrease in a Member’s Share under Section 3.2(b) will be determined as follows:

 (i) the Board will determine the fair market value of the Company’s assets before taking into account any new Capital Contributions
made in response to the Capital Call; 
 (ii) the Board will compute a “Special Sharing Amount” for each Member equal to the sum
of (A) the product of the fair market value determined in Section 3.2(d)(i) and such Member’s Share prior to the required increase or decrease and (B) the amount of new Capital Contributions made by such Member in response
to the Capital Call; and 
 (iii) each Member’s Share will be the percentage determined by dividing such Member’s Special Sharing
Amount by the sum of all Members’ Special Sharing Amounts. 
 3.3 Withdrawal and Return of Capital; Interest on Capital. No
Member has the right to withdraw any Capital Contributions, nor is any Member entitled to receive any interest on Capital Contributions or any portion thereof.

 4. DISTRIBUTIONS 

4.1 Limitations on Distributions. The Company will not make any distribution of cash, except to the extent that the Company then has
cash or cash equivalents available in excess of the sum of (a) amounts required to pay or make provision for all Company expenses, plus (b) all reserves that are considered necessary or appropriate by the Board. To the extent that
the Board reasonably foresees that the Company will receive cash or other consideration to satisfy liabilities not yet due and payable, the Company is not required to establish reserves or make other provision to satisfy the liabilities prior to
making distributions under this Article 4. Distributions of cash are only to be made to the extent cash or cash equivalents are available to the Company without requiring (i) the sale of Company assets or the pledge of Company
assets at a time or on terms that the Board believes are not in the best interests of the Company or (ii) a reduction in reserves that the Board believes are necessary or desirable for working capital or other Company purposes. No Member has
the right to receive a distribution of property other than cash. 
 4.2 Annual Distributions. Subject to the limitations of
Section 4.1, the Board will determine each year whether the Company has cash or cash equivalents in excess of the Company’s prudent working capital and liquidity needs (after giving effect to distributions described in Sections
4.3 and 4.4) and will distribute excess cash to the Members in proportion to their Share. 
 4.3 Special Distributions.
The Company will make the following distributions from time to time: 
 (a) As and when any New Member makes a Capital Contribution to the
Company pursuant to Section 3.1(c), the Company will distribute an amount equal to that Capital Contribution to B&WMR. 

(b) If BNGP makes an additional investment to true-up the First Tranche Investment as described in Section A.4(a) of Exhibit A,
the Company will distribute an amount equal to the true-up payment to B&WMR in accordance with Section A.4(a) of Exhibit A. 

(c) If any amount is due to BNGP to refund in-kind credit as described under Section A.4(b) of Exhibit A, the Company will
distribute that amount to BNGP. 
 (d) As and when an installment of the Second Tranche Investment is made in accordance with Section
A.6(b) of Exhibit A, the Company will distribute an amount equal to that installment to B&WMR in accordance with Section A.6(c) of Exhibit A. 

4.4 Tax Payment Distributions. 

(a) If the Board determines that the Company is expected to have taxable income for federal income Tax purposes in any Fiscal Year and the
Board elects to make a distribution pursuant to this Section 4.4, not more than thirty days after the end of each fiscal quarter in that Fiscal Year, the Company will distribute cash to the Members in proportion to the amount of taxable
income allocated to each of them for that Fiscal Year. The amount to be distributed as tax payment distributions will be based on the maximum federal income tax rate 

  
 5 








 
then applicable to corporations, increased by five percentage points or other rate as the Board determines is appropriate to account for expected state income Taxes net of the benefit of
deducting such Taxes for federal purposes, initially 40%. 
 (b) Any distribution made to a Member under this Section 4.4 will
be treated as having been distributed to that Member under the applicable provisions of Section 4.2 or Section 4.3, and will reduce, dollar for dollar, the amounts to which that Member would otherwise be entitled under
Section 4.2 and Section 4.3, so that the cumulative amounts distributed to the Members under this LLC Agreement will be the same as the respective amounts that the Members would have received if no distributions had been made
under this Section 4.4. 
 4.5 Liquidating Distributions. If the Company is being wound up and liquidated in accordance
with Section 17.2, or if there is to be a merger, consolidation, conversion, sale of all or substantially all the Company’s assets or other similar transaction, then, subject to the provisions of Section 4.1, all
distributions to the Members will be made to all Members in accordance with the positive Capital Account balances of the Members as determined after taking into account all capital account adjustments for the Tax Partnership taxable year during
which such liquidation occurs including the allocation of any Profit or Loss for that taxable year. A Member with a deficit in its Capital Account following the distribution of liquidation proceeds will have no obligation to restore the amount of
the deficit balance to the Company, any Member or other Person. Distributions made pursuant to this Section 4.5 will only be made after any distributions required pursuant to Sections 4.3 or 4.4 have been made. 

4.6 Withholding. The Company may withhold from any distribution made pursuant to this LLC Agreement, and may pay over to the
appropriate federal, state or local Governmental Authority, any amounts required to be withheld pursuant to the Code or provisions of Applicable Law. All amounts withheld pursuant to the preceding sentence in connection with a distribution to any
Member to satisfy a Tax imposed upon that Member will be treated as an amount distributed to that Member for all purposes of this LLC Agreement. 

5. CAPITAL ACCOUNTS 
 5.1
Financial Reporting and Nonfinancial Reporting Books. The Company will keep, or cause to be kept, financial reporting books on the accrual method of accounting in accordance with generally accepted accounting principles in the United States
consistently applied. The Company will maintain nonfinancial reporting books and Capital Accounts as required by Section 5.2 that are to be the basis for liquidating distributions pursuant to Section 4.5. The Company will
also maintain detailed books and records as required to complete and track the investments contemplated in Section 3.1 (and other accounts the Board determines are required to complete necessary project management controls in connection
therewith) and so that it can comply with all Tax reporting obligations and other obligations set forth in Article 14. 
 5.2
Capital Accounts. 
 (a) For U.S. federal, state and local income tax purposes, the Company is a continuation of the Tax Partnership
resulting from the JDA, under which each Member had a 

  
 6 








 
Capital Account, and the Members intend for the initial Capital Account of each Member hereunder to be equal to the Capital Account of each Member under the JDA. This Section 5.2 and
other provisions of this LLC Agreement relating to Capital Accounts are intended to comply with Treasury Regulations Sections 1.704-1(b) and 1.704-2, and they will be interpreted and applied in a manner consistent with those Treasury Regulations.

 (b) Each Member’s Capital Account will from time to time be increased by: 

(i) the amount of money contributed by that Member to the Company and the amount of any Company liabilities which the Member assumes (within
the meaning of Treasury Regulations Section 1.704-1(b)(2)(iv)(c)); 
 (ii) the fair market value of property (as determined by the
Board) contributed by that Member to the Company (net of any liabilities secured by the property that the Company is considered to assume or take subject or pursuant to Section 752 of the Code); and 

(iii) allocations to that Member of Profits (or items of income or gain) under Sections 6.1 and 6.2. 

(c) Each Member’s Capital Account will from time to time be reduced by: 

(i) the amount of money distributed to that Member by the Company (other than any amount distributed to BNGP under
Section 4.3(c)) and the amount of that Member’s liabilities which the Company assumes (within the meaning of Treasury Regulations Section 1.704-1(b)(2)(iv)(c)); 

(ii) the fair market value of property (as determined by the Board) distributed to that Member by the Company (net of any liabilities secured
by the property that the Member is considered to assume or take subject or pursuant to Section 752 of the Code); and 
 (iii)
allocations to that Member of Losses (or items of loss, deduction or expense) under Sections 6.1 and 6.2. 
 (d) For
avoidance of doubt: 
 (i) A Member’s Capital Account will not be increased in respect of any services rendered by that Member or its
Affiliates or the value of any intellectual property rights provided to the Company; 
 (ii) amounts paid by BWNE to BPC under the BPC TSA
(prior to its novation to the Company) will be regarded as a Capital Contribution by B&WMR to the Company and a payment by the Company to BPC for its services under the BPC TSA; and 

(iii) B&WMR will be treated as having paid BWNE, on behalf of the Company, for the BWNE services outlined in the DOR and Development
Budget (including related marketing, licensing interfacing, procurement, staffing, personnel, administrative and business development activities) that were performed prior to execution of the BWNE TSA, and as contributing the necessary funds to the
Company. 

  
 7 








 (e) No Member is obligated to restore to the Company or to repay to the Company or to any other
Person any portion or all of any debit Capital Account balance. 
 5.3 Revaluation of Company Property. 

(a) Upon the occurrence of a Revaluation Event, the Board will revalue all Company property (whether tangible or intangible) for Capital
Account purposes to reflect the Adjusted Fair Market Value of Company property immediately prior to the Revaluation Event. In the event that Company property is so revalued, the Capital Accounts of the Members will be adjusted in accordance with
Treasury Regulations Section 1.704-1(b)(2)(iv)(f). 
 (b) Upon the distribution of Company property to a Member, if Company property
is not revalued pursuant to Section 5.3(a), the property to be distributed will be revalued for Capital Account purposes to reflect the Adjusted Fair Market Value of that property immediately prior to the distribution, and the Capital
Accounts of all Members will be adjusted in accordance with Treasury Regulations Section 1.704-1(b)(2)(iv)(e). 
 6. PROFITS AND LOSS
ALLOCATION 
 6.1 Shares of the Company. 

(a) “Share” means: 

(i) with respect to BNGP, 10%, as may be adjusted after the Commencement Date in accordance with Section 3.2(b) (upward or
downward based on participation in Capital Calls, subject in all cases to Section 3.2(c)), Section A.5 of Exhibit A (downward for electing to cap the First Tranche Investment), Section A.6 of Exhibit A (upward
for investing the Second Tranche Investment), and Article 15 (downward in the event of a Transfer by BNGP); 
 (ii) with respect to
any other Member other than BNGP or B&WMR, the percentage set forth in the applicable Subscription Agreement or Joinder Agreement, as applicable, as may be adjusted after the date of the Subscription Agreement or Joinder Agreement, as
applicable, in accordance with Section 3.2(b) (upward or downward based on participation in Capital Calls) and Article 15 (downward in the event of a Transfer by the Member); and 

(iii) with respect to B&WMR, the percentage equal to the sum of (x) 100%, minus (y) BNGP’s Share (calculated
in accordance with Section 6.1(a)(i)), minus (z) each other Member’s Share (calculated in accordance with Section 6.1(a)(ii)). 

(b) For purposes of maintaining Capital Accounts, for each Fiscal Year or other relevant period, after making the allocations required by
Section 6.2, Profits and Losses will be allocated to the Members in proportion to their Share. To the extent any allocation of Losses to a Member would cause that Member to have a negative balance in its Adjusted Capital


  
 8 








 
Account at the end of a Fiscal Year, such Losses will be reallocated among the other Members, and allocations of Profits and Losses for future periods will be adjusted accordingly to offset (as
nearly as possible) such reallocation. 
 (c) If during any Fiscal Year there is a change in any Member’s Share (including a complete
termination of that Member’s interest), allocations for that year will take into account the varying Shares of the Members in any manner determined by the TRP consistent with the requirements of Section 706 of the Code. The TRP may, in its
sole discretion, use a “pro rata” method under Treasury Regulation Section 1.706-1(c)(2) in making the allocations, or may instead, in its sole discretion, apply a “closing of the books” method. 

(d) Each Member’s Share as of the Commencement Date is set forth opposite its name on Annex III. For administrative convenience,
Annex III will be updated from time to time to reflect changes in each Member’s Share; however, any change in a Member’s Share shall be effective as and when determined under this LLC Agreement, not when Annex III is updated.

 6.2 Special Allocations. 

(a) Notwithstanding any other provision of this Article 6, if there is a net decrease in Partnership Minimum Gain or Partner
Nonrecourse Debt Minimum Gain (determined in accordance with the principles of Treasury Regulations Sections 1.704-2(d) and 1.704-2(i), respectively) during the Fiscal Year, each Member will be specially allocated items of Company income and gain
for that year (and, if necessary, subsequent years) in an amount equal to its respective share of the net decrease during that year, determined pursuant to Treasury Regulations Sections 1.704-2(g) and 1.704-2(i)(5). The items to be so allocated will
be determined in accordance with Treasury Regulations Section 1.704-2(f). This Section 6.2 is intended to comply with the minimum gain chargeback requirements in the Treasury Regulations and will be interpreted consistently
therewith, including that no chargeback will be required to the extent of the exceptions provided in Treasury Regulations Sections 1.704-2(f) and 1.704-2(i)(4). 

(b) In the event any Member unexpectedly receives any adjustments, allocations, or distributions described in Treasury Regulations
Section 1.704-1(b)(2)(ii)(d)(4), (5) or (6), items of Company income and gain will be specially allocated to that Member in an amount and manner sufficient to eliminate, to the extent required by the Treasury Regulations, the Adjusted
Capital Account Deficit created by the adjustments, allocations or distributions as promptly as possible. An allocation pursuant to this Section 6.2(b) will be made only if and to the extent that a Member would have an Adjusted Capital
Account Deficit in excess of that sum after all other allocations provided for in this Section 6.2(b) have been tentatively made as if this Article 6 were not in this LLC Agreement. 

(c) In the event any Member has an Adjusted Capital Account Deficit at the end of any Fiscal Year, each such Member will be specially
allocated items of Company income and gain in the amount of such excess as quickly as possible. An allocation pursuant to this Section 6.2(c) will be made only if and to the extent that a Member would have an Adjusted Capital Account
Deficit in excess of that sum after all other allocations provided for in this Article 6 have been tentatively made. 

  
 9 








 (d) Nonrecourse Deductions will be specially allocated to the Members in proportion to their
Shares. 
 (e) Any Partner Nonrecourse Deductions for any Fiscal Year or other period will be specially allocated to the Member who bears
the economic risk of loss with respect to the Partner Nonrecourse Debt to which the Partner Nonrecourse Deductions are attributable in accordance with Treasury Regulations Section 1.704-2. 

(f) Any income attributable to the receipt or accrual of any financial assistance from the DOE or other U.S. Governmental Authority as
described in Section B.4 of Exhibit B shall be allocated one hundred percent (100%) to B&WMR. 
 6.3 Allocation of
Tax Items. 
 (a) Except as otherwise provided in this Article 6, all items of income, gain, loss, and deduction will be
allocated among the Members for federal income tax purposes in the same manner as the corresponding items were allocated under Section 6.1 and Section 6.2. 

(b) If the fair market value of an item of Company property differs from its Tax Basis, allocations of depreciation, depletion, amortization,
gain and loss with respect to that property will be made for federal income tax purposes to take account of the variation between the Tax Basis and fair market value of the property under Section 704(c)(1)(A) of the Code and Treasury
Regulations Section 1.704-1(b)(4)(i). The TRP may select, in its discretion, any reasonable method or methods for making the allocations, including any method described in Treasury Regulations Sections 1.704-3(b), (c), or (d). 

7. MANAGEMENT OF THE COMPANY 

7.1 Governing Board; Alternates. 

(a) The business and affairs of the Company will be managed by or under the direction of a board of directors (the “Board”
and each member of the Board, a “Director”). For the avoidance of doubt, the Board will collectively by authorized action have all, and no Director individually will have any, of the rights and powers that are possessed by a manager
pursuant to Section 18-402 of the Act, subject to the provisions of this LLC Agreement. 
 (b)
An Alternate will have the full power to act as a Director designated by the Member that designated the Alternate. Any action by an Alternate will be final and binding upon the Member that designated that Alternate. Any action or inaction purported
to be taken or action refrained from by an Alternate (including voting with respect to a particular matter (including matters set forth in Section 7.5), waiving notice of any meeting, and executing a written consent) will be deemed to be
the action or inaction of a Director designated by the Member that designated the Alternate. 
 7.2 Composition. The Board will
consist of no fewer than three Directors. The number of Directors and those designated by B&WMR will be increased from time to time by resolution of the Board in connection with the admission of new Members and as necessary so that the Directors
designated by B&WMR will always constitute a majority of the Board, in each case 

  
 10 








 
without the need to amend this LLC Agreement. The Directors and Alternates will be designated by individual Members as follows: 

(a) B&WMR will at all times be entitled to designate a majority of the Directors and one Alternate for each director it is entitled to
designate; 
 (b) for so long as BNGP is a Founder, it will be entitled to designate one Director and one Alternate; and 

(c) other Members (subject to Section 7.2(a)) may designate individuals to the Board as determined by B&WMR. 

7.3 Term; Vacancies. Each Director and Alternate will hold office until his or her resignation, removal, death or incapacity. Each
Director and Alternate will hold office at the pleasure of the Member that designated that Director. A Director or Alternate may be removed at any time, for any reason or no reason, by written notice by the Member that designated that individual
delivered to the other Members. If a Member is no longer entitled to designate an individual to serve on the Board, the Director(s) and Alternate(s) previously designated by that Member may be removed at any time, for any reason or no reason, by the
Board (excluding the vote of the subject individuals). If a vacancy occurs on the Board or in the position of Alternate for any reason, the vacancy will be filled by the written designation of the Member entitled to fill the vacancy. The Board will
promptly notify the Members of any changes to the individuals designated as Director or Alternate. 
 7.4 Required Approval by the
Board. Subject to the limitations imposed by the Act and Sections 7.5(a) and 9.12, the following decisions and actions will be vested exclusively in the Board or, as delegated by the Board, a committee of the Board: 

(a) distributions under Sections 4.2 and 4.4; 

(b) Capital Calls pursuant to Section 3.2(b); 

(c) adoption of or changes in policies relating to governance of the Company or other Company policies; 

(d) retention, termination and compensation of those Officers who are employees of the Company; 

(e) issuing material debt or entering into obligations for money borrowed; 

(f) changes in accounting principles, methods or practice, changes in the Fiscal Year or changes in the taxable year or any material method
of tax accounting; 
 (g) except as otherwise set forth in the Development Budget, any material expenditures or commitments to make a
material sum of funds available; 
 (h) entry into material contracts or material amendments to material contracts, including Customer
Contracts; and 

  
 11 








 (i) creation of or material changes to employee benefit plans or programs. 

7.5 Negative Controls.  

(a) For so long as BNGP is a Founder (except in the case of actions subject to Section 7.5(a)(i), which will require approval of
BNGP for so long as it is a Member), the following actions can only be taken if approved by an affirmative vote of a majority of the Board, including the Director designated by BNGP: 

(i) (y) deployment of any Plant or (z) the submission of a proposal or negotiation of a Customer Contract, in each case for a Plant that
would be located in a jurisdiction that does not have an Acceptable Nuclear Liability Regime; 
 (ii) transactions that would cause
B&WMR or its Affiliates to have, in the aggregate, less than a 51% Share in the Company, prior to BNGP satisfying its obligations with respect to the First Tranche Investment and the Second Tranche Investment; 

(iii) approval of Customer Contracts not in accordance with Section G.3 of Exhibit G; 

(iv) admission of a New Member not in accordance with Section C.4 of Exhibit C; 

(v) execution by the Company (or its designated subsidiary) of a Customer Contract or any material amendment thereto, or submission of a
proposal to a potential Customer, that, despite any proposed mitigation, deviates significantly from the Customer Contract Principal Terms and Conditions set forth in Exhibit J; 

(vi) appointment or removal of the CEO; 

(vii) until the Design Completion Date, significant modifications to the categories of costs with respect to work performed by BPC as set
forth in the Development Budget or the DOR; or 
 (viii) submission of the DCA, any amendment to the DCA, or formal transmittal to a
Customer of a license or permit application prepared by the Company for ultimate submission to the NRC by a Customer (excluding any related Requests for Additional Information). 

(b) With respect to each of the matters set forth in clauses (iv) through (viii) of Section 7.5(a), the affirmative
vote of the Director designated by BNGP will not be unreasonably withheld, conditioned or delayed. Neither the Board nor any committee of the Board may take, and B&WMR will not take, action to authorize the Company to take any action that is
subject to the approval requirements of Section 7.5(a) unless the Director designated by BNGP gives the required approval. 

  
 12 








 (c) General business development activities that have not reached the level of
specificity described in Section 7.5(a)(i) in a jurisdiction that does not have an Acceptable Nuclear Liability Regime are not subject to the negative control provisions of Section 7.5(a)(i). 

7.6 Meetings. The Board will meet at least annually and at any other times as the Board determines. Meetings will be held at the
Company’s principal place of business or at any other place as the Board determines. Special meetings of the Board may be called by the CEO or by any Director. B&WMR will designate a Chairperson of the Board (the
“Chairperson”) from among the Directors designated by B&WMR. The Chairperson will preside, or delegate another Director to preside in the event the Chairperson is unable to attend the meeting, over each meeting of the Board.
Each Alternate and one senior manager designated by each Founder in writing to the Board (as may be changed from time to time by written notice to the Board) will be permitted to attend Board meetings as guest attendees, except for such portions of
a meeting when the Board elects to meet in executive session without any guests. 
 7.7 Agenda and Notice of Meetings. The
Chairperson will provide a written notice at least three Business Days prior to any meeting of the Board, which will state the place, date and time for the meeting, as well as the proposed agenda and anticipated permitted attendees for the various
agenda items for that meeting. Each Director may provide the Chairperson with agenda items and proposed additional invitees for the meeting. The Chairperson will be responsible for preparing the final agenda after this Director input. 

7.8 Waiver of Notice of Meeting. The requirement to receive notice of a meeting may be waived by any Director either before or after
the meeting and will be waived by any Director participating in the meeting unless objection to the notice is made by the Director at the start of the meeting. Failure to specify a particular subject or purpose in the notice of a meeting will not
invalidate any action otherwise properly authorized. A waiver by the BNGP Director with respect to a specific meeting and specific subjects to be reviewed or acted upon at that meeting or a specific agenda for that meeting will also constitute a
waiver of the quorum requirement as to Board action taken at that meeting with respect to the matters identified in the waiver. 
 7.9
Telephonic Meetings. Any meeting of the Board may be held by conference telephone or other communication equipment so long as all members participating in the meeting can hear and be heard by one another. All members participating by
telephone or other communication equipment will be deemed to be present in person at the meeting. 
 7.10 Required Vote; Quorum. Each
Director will be entitled to cast one vote with respect to any decision to be made by the Board. Subject to Section 7.5(a), any decision to be made by the Board or a committee of the Board will require the affirmative vote of a majority
of a quorum. The presence of a majority of the Directors then in office, including in all cases the BNGP Director (if BNGP has a Director on the Board) and a sufficient number of B&WMR Directors so that the B&WMR Directors constitute a
majority of the quorum, constitutes a quorum for the transaction of business at any meeting of the Board. Except as otherwise set forth in the charter or Board Resolutions forming the committee, the presence of a majority of the Committee Members
will constitute a quorum for the transaction of any business at any meeting of that committee of the Board including, in all cases in which BNGP is affiliated with an individual Committee Member, at least one BNGP Committee Member. 

  
 13 








 7.11 Action by Written Consent. 

(a) Any action required or permitted to be taken by the Board may be taken without a meeting if a consent in writing, setting forth the action
so taken, is executed and delivered by all the Directors then in office. Any unanimous written action will be effective immediately unless otherwise set forth in the written action. 

(b) If the Board is unable to convene because of a lack of quorum or unable to take timely action under
Section 7.11(a), any action required or permitted to be taken by the Board may be taken without a meeting if a consent in writing, setting forth the action so taken, is executed and delivered by those Directors whose vote would be
required to approve the action at a meeting. Action by the Board under this Section 7.11(b) is only effective if all Directors have received a complete written description of the action to be taken at least five Business Days prior to
the execution date of the consent for the action. During the five Business-Day period, any Director will have the right to call a meeting of the Board to discuss the proposed action, and no written consent will be valid until the meeting has taken
place. 
 7.12 Compensation and Reimbursement. Directors will not be compensated by the Company for services rendered in their
capacity as Directors. The Company may reimburse the Directors for all reasonable out-of-pocket expenses that the Directors may incur in connection with the performance of their duties as Directors. 

7.13 Committees. The Board may create one or more committees consisting of a subset of Directors or other individuals (each a
“Committee Member”). Provisions regarding notice of meetings and minutes of meetings of the Board apply equally to committees of the Board. Individuals affiliated with B&WMR will constitute a majority of the members of any
committee of the Board. Subject to the terms of the Board resolution forming the committee, or its charter approved by the Board, any committee created by the Board may be dissolved or its members removed or replaced by the Board at any time. 

7.14 Waiver of Conflict of Interest. 

(a) Directors and Committee Members that are affiliated with a Member will serve as representatives of that Member and will owe no fiduciary
duties to the Company or the other Members; provided, that in the absence of a conflict of interest between a Member and the Company, it is intended that a Director or Committee Member will act in the best interests of the Company. The Company and
each Member hereby waives, on behalf of itself and its Affiliates, any claim or cause of action against (i) any other Member and its Affiliates, (ii) any Director designated by or at the direction of any other Member, or (iii) any
Committee Member affiliated with any other Member, in either case for any breach of fiduciary duty to the Company by that Member, any of its Affiliates, or the Director or Committee Member affiliated with that Member as a result of a conflict of
interest between the Company and the Member that designated that Director or that is affiliated with that Committee Member or any of its Affiliates. 

(b) In the event of any conflict of interest, each Member, any of its Affiliates, or a Director or Committee Member may act in the best
interest of the Member that designated the Director or that is affiliated with the Committee Member. This Section 7.14(b) entitles a 

  
 14 








 
Member and its Affiliates to prefer the interests of the Member over the interests of the Company or any other Member but does not permit (i) action taken solely to harm the Company or
another Member or (ii) any breach of this LLC Agreement or any other agreement between the Member or its Affiliates, on the one hand, and the Company or another Member, on the other, that relates to the Program or the Company. 

(c) No Director or Committee Member will be obligated to reveal confidential or proprietary information belonging to the Member that
designated that Director or that is affiliated with the Committee Member (or to that Member’s Affiliates), without the consent of that Member. No Director or Committee Member will be obligated to recommend or take any action in that
Person’s position as a Director or Committee Member that prefers the interests of the Company over the interests of a Member or any of its Affiliates, and each other Member, Director and the Company hereby waives the fiduciary duty, if any,
owed it or the Company of that person in the event of any such conflict of interest. 
 7.15 Management of Subsidiaries. The
provisions of this LLC Agreement relating to the management and control of the business and affairs of the Company, and the respective rights and duties of, and restrictions on the Board and the Members with respect thereto will also be construed to
be fully applicable to the management and control of any subsidiary of the Company. 
 7.16 Contracts. The Board may authorize any
Director, Member, Officer or agent of the Company to enter into any contract or execute any instrument in the name of, and on behalf of, the Company, and the authority may be general or confined to specific instances. 

7.17 Information Rights. Each Director will have full access to Company books, records, personnel, and facilities solely in order to
stay informed of Company matters and for use in furtherance of the Program. 
 8. OFFICERS AND PERSONNEL 

8.1 Officers. 
 (a) The
Board will appoint a CEO and may, from time to time, appoint other officers (collectively, “Officers”) and delegate to one or more Officers the authority and duties that the Board may deem advisable. 

(b) Each Officer will hold office until his or her resignation, removal, death or incapacity. An Officer may be removed at any time by the
Board, with or without cause. Any Officer may resign at any time by delivering his or her written resignation to the Board. An individual can be appointed to more than one office. 

(c) Any delegation of authority or duties pursuant to this Section 8.1 or 8.2 may be revoked at any time by the Board.

 8.2 Authority and Duties of the Officers. Subject at all times to the authority of the Board, each Officer will have the authority
and duties delegated to the Officer by the Board and will devote to the Company the amount of time as is reasonably necessary and his or her best efforts to carry out the business of the Company and to accomplish its purposes. 

  
 15 








 8.3 Personnel. From time to time, the Company may enter into agreements with Members or
their Affiliates pursuant to which employees may be seconded to the Company and the Company may hire other employees at the direction of the CEO. Officers and employees (including seconded employees) will be bound by the Company policies adopted by
the Board. 
 9. RIGHTS AND OBLIGATIONS OF MEMBERS 

9.1 Initial Members. The initial Members of the Company are B&WMR and BNGP, each of which is admitted to the Company as a Member
effective as of the date of this LLC Agreement. 
 9.2 Additional Members. One or more New Members may be admitted to the Company in
accordance with the terms, and subject to the limitations, of Exhibit C. Each New Member will execute a Subscription Agreement in which the person agrees to be bound by all of the provisions of this LLC Agreement in accordance with Exhibit
C. Additional Members that are admitted to the Company pursuant to a transfer of Membership Interests in accordance with Article 15 will execute a Subscription Agreement or Joinder Agreement, as applicable. 

9.3 Withdrawal and Termination. Except as provided in this Section 9.3, no Member has the right to withdraw from the
Company. Each of B&WMR and BNGP has the right to Terminate the Program and BNGP may, and B&WMR has the right to cause BNGP to, Withdraw from the Company, in each case in accordance with Exhibit D. B&WMR has the right to cause any
Member other than BNGP to Withdraw from the Company in accordance with the terms of that Member’s Subscription Agreement or Joinder Agreement and Exhibit D. 

9.4 Limitation on the Rights and Powers of Members. Subject to any mandatory requirements of the Act and actions requiring Member
Approval under Sections 9.12, 13.4(a), 14.3, 14.5, 17.2(a), and 17.5, no action taken by the Board or the Company requires the prior vote of the Members. No Member (in its capacity as a Member) has the right
to take any part whatsoever in the management and control of the ordinary business of the Company, sign for or bind the Company, act on behalf of the Company (including with respect to lobbying efforts or interfacing with Governmental Authorities),
compel a sale or appraisal of Company assets, or sell or assign its Membership Interests in the Company except as provided in Article 15. No individual Member has the right to demand a partition or appraisal of Company property or to force a
dissolution of the Company. This Section 9.4 does not negate any provision of this LLC Agreement that requires the approval of the Founders or any particular individual Member. 

9.5 Limited Liability of Members. Except as otherwise agreed by a Member, Members are not liable for the debts, liabilities, contracts
or any other obligations of the Company and, except for contributions specifically required under Section 3.1 or agreed to by a Member as contemplated by Section 3.2(b), are not required to make any additional contributions
or payments to the Company. 
 9.6 Spontaneous Meeting of Members. No annual or regular meetings of the Members as Members will be
required. If a quorum of all the Members meet at any time and place, either within or outside the State of Delaware, and consent to the holding of a meeting at that time and place, the meeting will be valid without call or notice. 

  
 16 








 9.7 Quorum. At each meeting of the Members, holders representing a majority of the Shares
of the Company, present in person or by proxy, will constitute a quorum for the transaction of Company business. In the absence of a quorum, any Member present at a meeting in person or by proxy will have the power to adjourn that meeting until a
quorum will be constituted. 
 9.8 Voting of Interests. Each Member will be entitled to vote based on their Share in connection with
any matter submitted to a vote at a meeting of the Members. 
 9.9 Manner of Acting. Except for actions that require a Member
Approval, that are reserved for the Board under Section 7.4 or are subject to BNGP negative controls under Section 7.5(a), the affirmative vote of the holders representing a majority of the Shares of the Company represented
at a meeting at which a quorum is present will constitute an act of the Members. 
 9.10 Action Without Meeting. Any action required
to, or that may, be taken by the Members may be taken without a meeting if consent thereto in writing, setting forth the action so taken, will be signed by the holder or holders representing not fewer than the minimum Share that would be necessary
to take the action at a meeting at which the Members entitled to vote on the action were present and voted. 
 9.11 No Required Notice of
Action. If the approval of Members representing the minimum Share required to take the action has been obtained, no notice of the action is required to the other Members. 

9.12 Actions Requiring Member Approval. 

(a) Without first obtaining a Member Approval, the Company will not take any action (or consent to the taking of any action) that would
effect any: 
 (i) divestiture, merger, consolidation, business combination, or similar transaction that would change the purpose of the
Company or make it impossible to implement the Program; 
 (ii) registration under the Securities Act (or comparable statute) of securities
of the Company or any subsidiary; and 
 (iii) filing for any court-supervised recapitalization, reorganization or bankruptcy proceeding by
the Company or any subsidiary. 
 (b) If the Company issues new equity that would materially and adversely affect an individual Member
without similarly affecting the rights of all Members similarly situated, the consent of the affected Member is required. Any issuance that would materially and adversely affect a group of Members will require the affirmative approval of a majority
of the Shares of the Company held by those affected and, if Section 7.5(a) applies, the Director designated by BNGP. 

  
 17 








 9.13 Information; Reports. 

(a) Each Member has the right, subject to reasonable restrictions approved by the Board (to avoid disruption of the Company’s business
and to protect the Company’s confidential information), to access information regarding the financial condition of the Company. 
 (b)
The Company will provide to each Member quarterly financial statements as determined by the Board, as soon as practicable after each fiscal quarter, prepared in accordance with generally accepted accounting principles of the United States
consistently applied. 
 10. INDEMNIFICATION OF INDIVIDUALS BY THE COMPANY 

10.1 General. The Company will indemnify, defend and hold harmless the current and former Officers, employees and seconded employees of
the Company and, only to the extent contemplated by Section 10.6, Directors, Alternates (when acting in their capacity as Directors) and Committee Members of the Company (each an “Indemnified Person”), from any
liability, loss, or damage incurred by the Indemnified Person by reason of any act performed or omitted to be performed by the Indemnified Person in connection with the business of the Company and from liabilities or obligations of the Company
imposed on that Person by virtue of that Person’s position with the Company, including reasonable attorneys’ fees and costs and any amounts expended in the settlement of any such claims of liability, loss, or damage. Indemnification under
this Section 10.1 will be recoverable only from the assets of the Company and not from any assets of the Members. 
 10.2
Exculpation. No Indemnified Person will be liable, in damages or otherwise, to the Company or to any Member for any loss that arises out of any act performed or omitted to be performed by that Indemnified Person pursuant to the authority
granted by this LLC Agreement or the applicable Secondment Agreement. 
 10.3 Limitations. 

(a) Indemnification under Section 10.1 and exculpation under Section 10.2 will be available only if (a) either
(i) the Indemnified Person, at the time of the action or inaction, believed, in good faith, that its, his, or her course of conduct was in, or not opposed to, the best interests of the Company, or (ii) in the case of inaction by the
Indemnified Person, the Indemnified Person did not intend its, his, or her inaction to be harmful or opposed to the best interests of the Company, and (b) the action or inaction did not constitute fraud, gross negligence, or willful misconduct
by the Indemnified Person or the seconded employee. 
 (b) If the Indemnified Person is (y) entitled to indemnification by another
Person or (z) is a beneficiary of an insurance policy with respect to the matter that is the subject of the proposed indemnification or exculpation, the Indemnified Person must use reasonable efforts to seek indemnity or coverage by that Person
or insurance policy, as applicable, before the Company will be obligated to indemnify the Indemnified Person pursuant to Section 10.1. 

  
 18 








 10.4 Advancement of Expenses. Expenses (including attorneys’ fees) incurred by the
Indemnified Person in defending any civil, criminal, administrative or investigative action, suit or proceeding may be paid by the Company as determined by the Board (and in the case of Directors and Alternates (when acting in their capacity as
Directors), are to be paid by the Company) in advance of the final disposition of such action, suit or proceeding upon receipt of an undertaking by or on behalf of the Indemnified Person to repay the amount if it is ultimately determined that the
Indemnified Person is not entitled to be indemnified as authorized in this Article 10. 
 10.5 Continuation of
Indemnification. The indemnification and advancement of expenses will, unless otherwise provided when authorized or ratified, continue as to an Indemnified Person who has ceased to be a Director, Officer or employee, as the case may be, and will
inure to the benefit of the heirs, executors and administrators of the Indemnified Person. 
 10.6 Indemnification of Directors,
Alternates and Committee Members. Individual Directors, Alternates and Committee Members will be indemnified by the Member that either designated that individual or is affiliated with that individual, as applicable, and the Company will not
indemnify Directors, Alternates or Committee Members except (i) those (if any) designated by the Board as “independent” and (ii) all Directors, Alternates (when acting in their capacity as Directors) or Committee Members to the
extent any of them are vicariously liable for actions taken by management of the Company. 
 10.7 Permitted Reliance on Reports, Advisors
and Information. Any Member and any Director, Committee Member, Officer, or employee of the Company in the performance of his or her duties, is entitled to rely in good faith on information, opinions, reports, or other statements, including
financial statements, books of account, and other financial data, if prepared or presented by (i) one or more Officers or employees of the Company if the person relying on the statements reasonably believes that the person preparing or
presenting the material is reliable and competent in that matter or (ii) legal counsel, public accountants, or other Persons as to matters that the person relying on the statements reasonably believes are within the Person’s professional
or expert competence. 
 10.8 Insurance. The Company will have power to purchase and maintain insurance on behalf of any Indemnified
Person or any person who is or was serving at the request of the Company as a director, officer, employee or agent of another Person against any liability asserted against him or her and incurred by him or her in any such capacity or arising out of
his or her status as such, whether or not the Company would have the power to indemnify him against such liability under the provisions of the Act. 

11. REPRESENTATIONS AND WARRANTIES 
 Each
Founder represents and warrants as of the Commencement Date, and each other Member represents and warrants as of the date of its Subscription Agreement or Joinder Agreement, as applicable, that: 

11.1 Investment Intention and Restrictions on Disposition. It is acquiring the Membership Interests solely for its own account for
investment and not with a view to resell. It 

  
 19 








 
agrees that it will not, directly or indirectly, Transfer or offer to Transfer, any of the Membership Interests (or solicit any offers to Transfer, buy, purchase or otherwise acquire or take a
pledge of any of the Membership Interests) or any interest therein or any rights relating thereto, except in compliance with the Securities Act, all applicable state securities or “blue sky” laws and this LLC Agreement, as the same may be
amended from time to time. 
 11.2 Securities Laws Matters. It understands that (i) the Membership Interests have not been
registered under the Securities Act or qualified under any state securities or “blue sky” laws, (ii) it is not anticipated that there will be any public market for the Membership Interests, (iii) the Membership Interests must be

stop-transfer instructions will be issued to the transfer agent with respect to the Membership Interests. 
 11.3 Ability to Bear
Risk. Its financial situation is such that it can afford to bear the economic risk of holding the Membership Interests for an indefinite period and it can afford to suffer the complete loss of its investment in the Company.

the Company has been made to it by or on behalf of the Company, (y) it has relied upon its own independent appraisal and investigation, and the advice of its own counsel, Tax advisors and other advisors, regarding the risks of an investment in
the Company, and (z) it will continue to bear sole responsibility for making its own independent evaluation and monitoring of the risks of its investment in the Company. 

  
 20 








 11.5 Organization and Existence. It has been duly organized and is validly existing and in

 11.8 No
Consents. No authorization, consent or approval of, notice to or filing with, any Governmental Authority or other Person, is required for the execution, delivery and performance by the Member of this LLC Agreement, except, as to B&WMR, for
lender consents or waivers associated with funding the Company.

performance by it of this LLC Agreement, the compliance with the terms and provisions of this LLC Agreement and the carrying out of the transactions contemplated hereby, conflicts or will conflict with or will result in a breach or violation of any
of the terms, conditions or provisions of any Applicable Law or the charter documents, as amended, or bylaws, as amended, of it or any order, writ, injunction, judgment or decree of any court or Governmental Authority against it or by which it or
any of its properties is bound, or any loan agreement, indenture, mortgage, note, resolution, bond, or contract or other agreement or instrument to which it is a party or by which it or any of its properties is bound, or constitutes or will
constitute a default thereunder or will result in the imposition of any lien upon any of its properties, except, as to B&WMR, for lender consents or waivers associated with funding the Company. 

11.10 No Violation of Law; No Proceedings. It is not in violation of any Applicable Law promulgated or judgment entered by any
Governmental Authority which violations, individually or in the aggregate, could have a material adverse effect on the performance of any of its obligations under this LLC Agreement. There are no suits or proceedings pending, or, to its knowledge,

 12. EXCLUSIVITY 

12.1 General. Except as otherwise agreed in writing that expressly references this Article 12 by the Member who or whose
Affiliate is protected by the exclusivity set forth in this Article 12, the Company and each Member will, and each will cause each of its Affiliates to, adhere to the terms of this Article 12. 

(a) For so long as BNGP maintains a Share in the Company equal to or greater than the First Tranche Profits Interest, the Company and
B&WMR will not, and each will cause their respective Affiliates not to, solicit or engage any architecture, engineering or contractor firm other than BPC, BDC and their Affiliates to (i) develop, market or sell nuclear-fueled power plants
constructed using a steam-generating light water SMR of 300 MWe or less per module, (ii) perform modifications or upgrades to work previously performed by BPC or its Affiliates under its scope of work set forth in the DOR, or
(iii) perform, or support performance of, any portion of the BPC Exclusive Scope with respect to any plant described in clause (i). 

(b) The Company and BNGP will not, and each will cause their respective Affiliates not to, solicit or engage any other steam-generating,
light water SMR designer or manufacturer other than BWNE and its Affiliates to (i) develop, market or sell nuclear-fueled power plants constructed using a light water SMR of 300 MWe or less per module, (ii) perform modifications or
upgrades to work previously performed by BWNE or its Affiliates under its scope of work set forth in the DOR, or (iii) supply, or support supply of, the NSSS or NSSS Extended Scope with respect to any plant described in clause (i). 

(c) The activities described in Sections 12.2 through 12.5 of this Article 12 will not violate or breach the
Company’s or a Member’s obligations under this Section 12.1. 
 12.2 Government Contracts. Members or their
Affiliates may each perform work under contracts with agencies of the U.S. Government except in an agency’s capacity as a potential Customer. 

12.3 Other Nuclear Technologies. BPC or its Affiliates may, in the normal course of its business, work on proposals and projects
involving the evaluation for Third Parties of multiple reactor technologies, which may potentially include light water SMR technologies other than the technology that is the subject of the Program. 

12.4 Competing Proposals. If a potential customer of a Member, an Affiliate of a Member, or the Company is considering developing or
utilizing nuclear technologies for a nuclear-fueled power plant, any Member (or their Affiliates) may have proposal or project team(s) proposing a technology solution that is not steam-generating light water SMR but each team will be independent of
the team supporting the Company. In that event, any Member with teams supporting competing proposals will ensure that reactor technology-specific information, related design information and other confidential information known to one proposal or
project team is “fire-walled” from each other proposal or project team, and not disclosed outside the proposal or project team, except for management review and approval activities and cost-estimation activities (as clarified below), which
will be conducted for each proposal or project independently of and without reference to other proposals and projects. In completing the 

  
 22 








 
competing proposal, the project teams may not use any Confidential Information of another Member, the Company or their respective Affiliates or otherwise be in violation of this Article 12
or Exhibit F. For the sake of clarity it is understood that, within BPC the assembly of the estimate for each competing proposal will be performed by a project estimator assigned specifically to that proposal effort such that the aggregate
estimate information will be “fire-walled”, but that BPC may assign discipline estimators to work across competing proposals for their respective disciplines. 

12.5 Customer Preference. (a) If a prospective Customer desires to select a constructor other than BPC or one of its Affiliates
for a Plant, then the Company may accommodate that prospective Customer’s preference only after FNTPs have been issued for four Plants under each of which BPC or one of its Affiliates has been engaged as the full EPC Subcontractor, and then
only if: 
 (i) BPC has been given a reasonable opportunity, jointly with the Company, to engage directly with the prospective Customer to
obtain the prospective Customer’s approval for BPC or one of its Affiliates to perform the work; and 
 (ii) the Company has used all
reasonable efforts to secure the prospective Customer’s agreement to the selection of BPC or one of its Affiliates, including arrangement of a meeting among executive management of the prospective Customer, BWNE and BPC. 

(b) If the conditions in this Section 12.5 are met and the potential Customer ultimately selects a constructor other than BPC or
one of its Affiliates, then BPC or its Affiliates will perform site specific engineering and all other EPC-related services with respect to the Plant not designated by the Customer to be performed by the other constructor, and the Generic Design Fee
will be payable to BNGP (or its designated Affiliate) even if BPC or its Affiliates is not engaged as the constructor for that Plant. 

13. COVENANTS; BUSINESS MATTERS 

13.1 Confidentiality. The Company and each Member will be bound by the terms of confidentiality set forth in Exhibit F. 

13.2 Compliance with Laws and Limits on Certain Activities. 

(a) The Company and, with respect to their participation in the Company, each Member will comply with all Applicable Laws of the pertinent
jurisdictions and the United States to the extent applicable to the Company including international fair dealing laws, including the United States Foreign Corrupt Practices Act (“FCPA”). With respect to the Company and each Member,
to be in compliance with the FCPA, its managers, directors, officers, employees, agents and anyone acting on its behalf, shall not pay, offer, promise to pay or authorize the payment directly or indirectly of any Company monies or anything of value

or any public international organization, or any employee thereof, or any person acting in an official capacity on behalf thereof for the purpose 

  
 23 








 
of securing any improper advantage or influencing any act or decision of any official or such government or institution in connection with any Company activities. No Member or their respective
Affiliates will make any such offer, payment, gift, promise or authorization to or for the use or benefit of any other Person if the Member knows or is aware that there is a high probability that the other Person will use such offer, payment, gift,
promise or authorization in violation of the preceding sentence. Each Member will immediately notify the CEO of any violation of this Section 13.2(a) that it becomes aware of. 

(b) No officer, manager or employee of a Member, or any person or entity acting on its behalf, shall be permitted by the Member to become an
official or employee of a government function having responsibility for regulation or oversight of any Company activities without the prior written consent of the Company. 

(c) No agent or representative shall be engaged by a Member or its Affiliates to act in connection with any Company activities without the
prior written consent of the Company. Each Member will take all reasonable steps to ensure that any agent or representative hired to act in connection with any Company activities abides by the obligations set forth in this Section 13.2.

 13.3 Customer Contracts and Subcontracts.

designated by BWNE, will be the exclusive supplier of (i) equipment comprised within the NSSS and NSSS Extended Scope as a subcontractor to the Company, (ii) Specified Equipment as and to the extent provided in Section G.5 of
Exhibit G, except as otherwise provided in Section 13.7, and (iii) technical support to the Company related to clauses (i) and (ii) as required in connection with start-up and initial operation and testing ((i)
through (iii) referred to collectively as the “BWNE Exclusive Scope”). 
 (c) For each Plant, subject to
Section 12.5, BPC, or an Affiliate designated by BPC, will be the exclusive provider of: (i) site-specific engineering, (ii) procurement, except as otherwise provided in Sections 13.3(b) and 13.7, (iii) Plant site
construction and fabrication, (iv) offsite fabrication and modularization, except for offsite manufacturing, skid mounting, and modularization of the scope of supply provided by BWNE or the Company, and (v) technical support to the Company
related to clauses (i) through (iv) as required in connection with start-up and initial operation and testing ((i) through (v) referred to collectively as the “BPC Exclusive Scope”). 

(d) With respect to each Plant, the Company will enter into contracts with BWNE (or its designated Affiliate) for the supply of equipment
comprised within the NSSS and 

  
 24 








 
NSSS Extended Scope (each, a “B&W Subcontract”) and, subject to Section 12.5, the Company will enter into contracts with BPC (or its designated Affiliate) for the
provision of the BPC Exclusive Scope (each, an “EPC Subcontract”). The principal terms and conditions for the B&W Subcontracts and EPC Subcontracts are set forth in Exhibit K. In negotiation of the B&W Subcontract and
EPC Subcontract for a specific project, BWNE, BPC (or their designated Affiliates) and the Company will use commercially reasonable efforts to accommodate the terms and conditions of the particular Customer Contract in the applicable subcontract to
the extent not inconsistent with the terms of Exhibit K. 
 13.4 Transactions with Affiliates. The Company may purchase or
sell goods or services or enter into any transaction with any Member or Affiliate of a Member and any profits or income earned by that Member or Affiliate as a result of the transaction will belong to it and not the Company. No Member has a right to
challenge an agreement, transaction or other arrangement between a Member (or an Affiliate of a Member) and the Company if the arrangement satisfies any of the following: 

(a) the agreement was specifically approved by a Member Approval; 

(b) the terms are no less favorable to the Company than would be available from independent Third Parties; or 

(c) the nature of the Member or its Affiliate’s interest was disclosed to the Board and the Board approved the agreement, transaction,
or other arrangement (it being understood that (i) BNGP’s interest in an EPC Subcontract or other subcontract with BPC or its Affiliates and (ii) B&WMR’s interest in a B&W Subcontract or other subcontract with BWNE or its
Affiliate’s needs no further disclosure). 
 13.5 Generic Design Fee. Subject to the terms of Section G.8 of Exhibit
G, the Company will pay to the designated Affiliates of B&WMR and BNGP the Generic Design Fee per NSSS module upon the Company receiving payment by the Customer of the initial payments required under the applicable Turnkey Contract on or
after FNTP. 
 13.6 Ethics Policies. Each Member represents and warrants that it will require its employees and representatives to
comply with Applicable Law and do nothing to cause the Company or any other Member to be in violation of any Applicable Law. Each Member represents and warrants that it has in place policies and procedures to detect and prevent any conduct in
connection with Program activities that would constitute a violation of Applicable Law related to the work connected to the Program. Specifically, each Member commits, with respect to Program activities, that it will, and will cause its employees
including any employees that it seconds to the Company or another Member or their respective Affiliates, to be in compliance with established policies and procedures governing ethics and compliance for that Member. 

13.7 Company Self-Performance. Subject to the terms of Section 13.3 and Exhibit C, it is the goal of the Company to
develop in due course the capability of performing the Program with its own employees. However, for each Plant, the Company will have the exclusive right to procure the Strategic Equipment subject to the terms of Section G.6 of Exhibit
G. 

  
 25 








 13.8 Political Contributions. The Company shall not spend any funds to make direct or
indirect contributions to federal, state or local political candidates, nor to make gifts or provide honoraria to federal, state or local elective or appointive officials without Board approval. All contributions, gifts or honoraria shall be made in
accordance with Applicable Law. 
 13.9 Publicity. No Member or any of its Affiliates will issue any press release or make any other
public disclosure regarding the Company, the Company’s activities, this LLC Agreement or the TSAs without obtaining the prior written approval of the Founders, which shall not be unreasonably withheld, conditioned or delayed. The Company will

permitted press release, public announcement or communication.

 14.3 Tax Matters Partner. The TRP will

 27 








 15.2 Permitted Transfers. Except as otherwise provided in Section 15.3 or any
Subscription Agreement, Members may Transfer their Membership Interests at any time in accordance with Sections 15.2(a) – (d), as applicable. 

(a) To/For The Benefit of Affiliates. A Member is permitted at any time to Transfer all or a portion of its Membership Interests to
one or more Affiliates so long as they remain Affiliates and, in the case of B&WMR, to lenders of BWNE or its Affiliates to effect a pledge of or security interest in B&WMR’s Membership Interests. 

(b) To Non-Affiliates. Subject to Section 15.4, a Member (other than BNGP) is entitled to Transfer all or a portion of its
Membership Interests to one or more Persons if: 
 (i) the terms of the Transfer are disclosed to the Board and to BNGP for it to evaluate
whether a negative control pursuant to Section 7.5(a) applies; 
 (ii) BNGP waives its negative control right set forth in
Section 7.5(a) (if applicable); and 
 (iii) the Person to whom the Membership Interests are Transferred executes a
Subscription Agreement. 
 (c) BNGP Transfers to non-Affiliates. Subject to Section 15.4, BNGP is entitled to Transfer
all or a portion of its Membership Interests to one or more Persons if the Second Tranche Investment has been paid in full and the Person to whom the Membership Interests are Transferred executes a Joinder Agreement. 

(d) Withdrawal. A Member shall make a Transfer if required in connection with a Member’s Withdrawal from the Company under
Section 9.3. 
 15.3 Prohibited Transfers. Notwithstanding Section 15.2, the following transfers are
prohibited:

 (c) Transfers by any Member to a B&WMR Competitor, or to any Person that poses a Reputational Risk to the Company
or the Program, as determined by B&WMR, except with B&WMR’s consent, which shall not be unreasonably withheld, conditioned or delayed. 

  
 28 








 (d) Transfers if, in the opinion of counsel for the Company, the Transfer would: 

(i) violate the Securities Act, or any applicable state securities or “blue sky” laws, or any other applicable provision of law in
any respect; 
 (ii) require registration of the Membership Interests under the Securities Act in connection with the Transfer; 

(iii) result in the Company having to register as an investment company under the Investment Company Act of 1940, as amended; or 

(iv) cause the Company to be treated as an association taxable as a corporation for purposes of the federal income tax laws. 

15.4 Duty of First Offer. (a) Subject to Section 15.4(b), if any Member (a “DOFO Member”) proposes to
Transfer its Membership Interests pursuant to Section 15.2(b) or Section 15.2(c) to a non-Member or non-Affiliate (a “First Offer Transaction”), the DOFO Member will, prior to pursuing any First Offer
Transaction, notify the other Members of its intention to pursue a First Offer Transaction (the “First Offer Transaction Notice”). The other Members will have the right, but not the obligation, to submit a proposal to purchase their
pro rata share (based on that Member’s Share compared to all other Members’ Share other than the Share of the DOFO Member) or more (i.e., oversubscribe) of the Membership Interests subject to the First Offer Transaction (the “First
Offer Proposal”) within twenty days following receipt of the First Offer Transaction Notice. The First Offer Proposal will include the price and other material terms the non-DOFO Member is prepared to offer. If a Member that is entitled to
make a First Offer Proposal elects not to do so, those Members that have elected to make a First Offer Proposal may offer to purchase such additional eligible shares on a pro rata basis. The DOFO Member may elect to accept some or all of the First
Offer Proposals. If the DOFO Member elects not to accept the First Offer Transaction Proposals (or has Membership Interests subject to the First Offer Transaction remaining that were not purchased in connection with First Offer Proposals), the DOFO
Member may enter into a First Offer Transaction with any Person if the terms and conditions of any such Transfer are not any less favorable to the DOFO Member than the terms and conditions set forth in any First Offer Proposal. The First Offer
Transaction will be consummated within 180 days following the date of the First Offer Proposals, and if not, any subsequent First Offer Transaction will be subject to the provisions set forth in this Section 15.4(a). Nothing in this
Section 15.4(a) will require the DOFO Member to enter into any First Offer Transaction under any circumstances. 
 (b)
B&WMR is only required to comply with Section 15.4(a) if, following the proposed Transfer, B&WMR’s Share would be less than 51% (unless the proposed Transfer is in connection with an Initial IPO approved by BNGP under
Section 9.12 or otherwise or any subsequent Transfer to public shareholders under a registered offering). 
 15.5 BNGP
Tag-Along Right. 
 (a) If B&WMR proposes to Transfer its Membership Interest pursuant to Sections 15.2(b) (other than a
Transfer in connection with an Initial IPO or any subsequent Transfer to public shareholders under a registered offering) and after the Transfer B&WMR or its Affiliates’ Share would be less than 51%, then at least thirty days prior to
effecting the 

  
 29 








 
Transfer, B&WMR will give BNGP written notice of the proposed Transfer. The notice will set forth the Membership Interests to be Transferred by B&WMR, the name and address of the proposed
transferee, the purchase price and that the proposed transferee has been informed of the tag-along right granted to BNGP under this Section 15.5. BNGP will then have the right, exercisable by written notice to B&WMR, to participate
in the sale, on the same terms and conditions as B&WMR, by selling up to its full ownership interest in the Company, on substantially the same terms (including with respect to representations and warranties and indemnification) as B&WMR.

 (b) If the proposed transferee does not agree to purchase BNGP’s Membership Interests directly from BNGP on the same terms and
conditions as specified in the notice given under Section 15.5(a), then B&WMR will have the right, but not the obligation, to purchase BNGP’s Membership Interests, solely for the purpose of selling those Membership Interests to
the proposed transferee on the terms set forth in the notice. If the proposed transferee does not elect to acquire BNGP’s Membership Interests (either directly or indirectly) subject to this tag-along right, B&WMR may not transfer its
interests to that proposed transferee in a transaction that would result in B&WMR or its Affiliates Share being less than 51%. 
 (c)
For the avoidance of doubt, B&WMR may elect to give rights to other Members to participate in a sale when B&WMR is selling all or a portion of its Membership Interest, subject in each case to the restrictions set forth in this Article
15. 
 15.6 B&WMR Drag-Along Right. 

(a) Subject to Section 15.6(d), if B&WMR agrees to sell all of its Membership Interests to a Third Party (a “Drag-Along Sale”), it has the right to require each other Member to Transfer its Membership Interests. B&WMR must give the other Members not less than ten days prior written notice describing in
reasonable detail the proposed Drag-Along Sale as to which it intends to exercise its rights under this Section 15.6, including the consideration to be paid and the name and address of the Third Party purchaser. 

(b) Each Member, if B&WMR elects to exercise its rights under Section 15.6, will (i) take any action as may be
reasonably requested by B&WMR in connection with consummating the transaction; (ii) vote in favor of, consent to and raise no objections against the transaction or the process pursuant to which the transaction was arranged; (iii) waive
any dissenter’s, appraisal and other similar rights; (iv) sell such Member’s Membership Interests on the non-price terms and conditions of the transaction as negotiated by B&WMR; and (v) execute and deliver such documents as
may be reasonably requested by B&WMR in connection with the transaction, including written consents of Members, proxies, letters of transmittal, purchase agreements and limited liability company interest powers. If B&WMR agrees to escrow any
amounts of proceeds resulting from a transaction or to accept indebtedness or other securities, or is subject to indemnification or other rights of offset, then each Member will be required to accept the same terms. 

(c) Each Member is only required to comply with Section 15.6(b) if B&WMR bears its proportionate share of any escrows,
holdbacks or adjustments in purchase price and make such representations, warranties and covenants as are customary. 

  
 30 








 (d) BNGP is only required to comply with Section 15.6(a) and 15.6(b) if
(i) it is no longer a Founder, (ii) the only representations and warranties it is required to make are authority to accomplish the sale and its ownership of the interests being sold, and (iii) the consideration that BNGP would receive
reflects its Share of the aggregate consideration received in the transaction less any Control Premium associated with the acquisition of B&WMR’s Membership Interest. The “Control Premium” is the additional amount an
arms-length purchaser is willing to pay in order to have control over the management of the affairs of the Company over the amount the purchaser would have paid if it did not obtain control over the Company as part of its purchase, as acknowledged
by the purchaser in writing. 
 15.7 General Provisions. 

(a) Each transferor under this Article 15 will reimburse or cause the reimbursement of the Company for all the Company’s
reasonable out-of-pocket expense relating to the Transfer, including all attorney’s fees, filing fees and similar expenses. 
 (b) If
the Board determines that a proposed Transfer under this Article 15 would, alone or in conjunction with one or more other Transfers, terminate the partnership that is the Company for federal income Tax purposes, the proposed Transfer can be
delayed until the earliest time, as determined by the Board that the Transfer may occur without causing a termination of the partnership that is the Company for federal income Tax purposes. If at any time more than one Transfer is being delayed
under this Section 15.7(b), the Transfers are to be made in the order in which the Board received notice of the proposed Transfer. If a Transfer or attempted Transfer causes a termination of the partnership that is the Company for
federal income Tax purposes, the Member making the Transfer or attempted Transfer is to be liable to the Company and each of the other Members for any Taxes, fines, penalties, damages, or losses which may be due as a result of the termination,
including costs of enforcement of the Company’s power to void or otherwise prohibit the Transfer or attempted Transfer. 
 (c) No
Transfer in compliance with this LLC Agreement, even if the transferee is a Member or is admitted as a Member, will release the transferor or former Member from those liabilities to the Company existing at the time of the transfer which survive the
Transfer. 
 15.8 Unauthorized Transfers Void. Any attempt by a Member, directly or indirectly, to Transfer, or offer to Transfer,
any Membership Interests or any interest therein or any rights relating thereto without complying with the provisions of this Article 15, will be void and of no effect. Any involuntary Transfer by operation of law will entitle the transferee
to the economic interest represented by the Membership Interests that were the subject of the Transfer but the transferee will not be a Member and will not have any rights under this LLC Agreement. 

16. LIMITATIONS ON LIABILITY AMONG THE MEMBERS 

16.1 Limitations on Liability. No Member or any of its Affiliates will be liable to the Company, another Member, or any of their
respective Affiliates for any consequential, incidental, punitive, exemplary, or indirect damages, lost profits, or other business interruption damages in connection with the Program. The preceding sentence applies without regard to the


  
 31 








 
cause or basis of any claim, and whether a claim is asserted in contract, tort, negligence, misrepresentation (including negligent misrepresentation), strict liability, statutory liability,
indemnity, or pursuant to any other theory of liability, even in the event of the fault, negligence (in whole or in part), or strict liability of, or breach of contract by, a Person whose liability is limited by this Section 16.1. The

(d) The Company will terminate when (i) all of the assets of the Company, after payment of or due provision for all debts, liabilities
and obligations of the Company shall have been distributed to the Members in the manner set forth in Section 4.5 and (ii) the Certificate of Formation shall have been canceled in the manner required by the Act.

 EXHIBIT D 

TERMINATION AND WITHDRAWAL 

In accordance with Section 9.3 of the Generation mPower Limited Liability Company Agreement, dated February 28, 2011 (the
“LLC Agreement”) to which this Exhibit is attached, this Exhibit D set forth the terms and conditions applicable to Termination of the Program and Withdrawal from the Company of a Member (other than B&WMR). Capitalized
terms used and not defined in this Exhibit have the meanings given to those terms in the LLC Agreement. References to “Sections” means sections of this Exhibit, unless otherwise specified. 

D.1 Termination of the Program for Significant Adverse Change in Business Prospects. 

(a) At any time B&WMR or BNGP each has the right to Terminate the Program by providing notice to the other Members if there has occurred a
significant adverse change in the business prospects for nuclear power generally or SMRs in particular or other similar significant adverse changes in the business prospects of the Program and: 

(i) the change is outside the control of the Members and their Affiliates; and 

(ii) there is no reasonable prospect that the significant adverse change may be remedied or mitigated in the foreseeable future by the
Members or their Affiliates exercising reasonable commercial efforts. 
 (b) For purposes of example and not limitation, a
“significant adverse change” under Section D.1(a) would include (A) identification of a fatal systemic flaw in the NSSS design; (B) the refusal or inability of the NRC to docket the DCA; or (C) a persistent failure to
obtain design certification from the NRC. 
 (c) If notice of Termination of the Program has been given under Section D.1(a),
and the cooling-off period described in Section D.6 has expired without a rescission of that notice, then: 
 (i) each Member will
bear the loss of its investment in the Program; 
 (ii) no Member will be obligated to make any payment to any other Member based on the
Termination of the Program; and 
 (iii) the Company, each Member and their Affiliates will cease all actions in furtherance of the Program
(except as required or permitted to Terminate the Program). 
 Termination of the Program under this Section D.1 will not affect the obligations of
the Members or their respective Affiliates under any Customer Contract, any B&W Subcontract, any EPC Subcontract, or any other subcontract under a Customer Contract. 







 (d) Following a Termination of the Program under this Section D.1, BNGP or its
Affiliates that were Members may remain Members in the Company, unless and until B&WMR elects to liquidate and dissolve the Company. Any dissolution of the Company under this Section D.1(d) may be completed by B&WMR in its sole
discretion and will not require Member Approval. At any time after the Program Termination Date, BNGP may unilaterally Withdraw from the Company. At the election of B&WMR at any time after the Termination of the Program under this
Section D.1, any remaining Members will work in good faith with B&WMR to amend the LLC Agreement to reflect the Termination of the Program and reflect the ongoing obligations, if any, of the Members. Following the Program Termination
Date, BNGP and its Affiliates may engage in preliminary discussions with Third Parties to perform services in connection with nuclear-fueled power plants constructed using a steam-generating light water SMR of 300 MWe or less per module without
being in violation of Section 12.1 of the LLC Agreement, however if BNGP or its Affiliates continue discussions for more than 60 days or execute any agreement (including a term sheet) with a Third Party related to such services, BNGP
will then be required to Withdraw from the Company. 
 D.2 Termination of the Program for Cessation of B&WMR Funding. 

(a) B&WMR or BNGP each has the right to Terminate the Program following notification or confirmation by B&WMR to BNGP that either:

 (i) the B&WMR or BWC board of directors has ceased funding of the Program for the indefinite future; or 

(ii) B&WMR and BWC are unable, for the foreseeable future, to provide funding for the Program. 

(b) If notice of Termination of the Program has been given under Section D.2(a), and the cooling-off period described in
Section D.6 has expired without a rescission of that notice, then: 
 (i) BNGP will be considered to have Withdrawn from the Company
as of the Program Termination Date; 
 (ii) B&WMR will pay BNGP an amount equal to the aggregate amount of investments in the Company
made by BNGP and its Affiliates under the JDA and Exhibit A through the Date of Withdrawal; and 
 (iii) the Company, each Member
and their Affiliates will cease all actions in furtherance of the Program (except as required or permitted to Terminate the Program). 
 Except for the
amount, if any, due under the last sentence of Section A.4(b) of Exhibit A, the payment determined under Section D.2(b)(ii) will be BNGP’s exclusive remedy for a Termination of the Program under this Section D.2.
Termination of the Program under this Section D.2 will not affect the obligations of the Members or their respective Affiliates under any Customer Contract, any B&W Subcontract, any EPC Subcontract, or any other subcontract under a
Customer Contract.

cure the failure. 
 (c) If a notice of Withdrawal has been given under Section D.3(a), and the cooling-off period described in

 (i) if the Date of Withdrawal occurs before the First
Tranche Investment has been contributed in full, B&WMR will pay BNGP an amount equal to the greater of (1) one hundred and fifty percent (150%) of the investments in the Company by BNGP and its Affiliates under the JDA and Exhibit

the LLC Agreement; or 
 (ii) there has been a persistent failure of the Company, without due cause, to pay BPC for work authorized and
performed under the BPC TSA (other than de minimis amounts) after the Company has received notice of the failure to pay in accordance with the BPC TSA that references Section D.4(a)(i) and has been given a reasonable opportunity to
cure the failure; or 
 (iii) there has been a persistent failure of the Company, without due cause, to carry out its Development Budget
Activities after the Company has received notice of the failure that references Section D.4(a)(i) and has been given a reasonable opportunity to cure the failure.

from the Company under this Section D.4, then B&WMR will only be obligated to make the withdrawal payment due under Section D.4(c) if (i) the Company action or
inaction that triggered BNGP’s Withdrawal (the “Subject Action”) was taken or confirmed by the Board, (ii) prior to the Board taking or confirming the Subject Action the BNGP Director had objected to the Subject Action and
identified it as an action that would trigger BNGP withdrawal rights, and (iii) one or more of the Directors designated by B&WMR voted in favor of the Subject Action. 

D.5 B&WMR Right to Cause Withdrawal of BNGP. 

(a) B&WMR has the right to cause BNGP to Withdraw from the Company by providing written notice to BNGP following: 

(i) a material breach of a material provision of the LLC Agreement by BNGP or its Affiliates or, prior to the Design Completion Date, a
material breach of a material provision of the BPC TSA by BPC or its Affiliates; or 
 (ii) a Change of Control of BNGP or an Affiliate of
BNGP that results in direct or indirect control of BNGP or its Affiliate by a Person (or an Affiliate of that Person) that is a B&WMR Competitor, or that poses a Reputational Risk to the Company, the Program, B&WMR, BWNE or BWC. 

(b) For purposes of example and not limitation: 

(i) a “material breach of a material provision” of the LLC Agreement by BNGP or one or more of its Affiliates shall have occurred
if BNGP or any of its Affiliates breaches the provisions of Article 12 or Section 13.2(a) of the LLC Agreement; and 

(ii) a “material breach of a material provision” of the BPC TSA shall have occurred if there has been a persistent failure of BPC,
without due cause, to carry out Development Budget Activities authorized under the BPC TSA after BPC has received notice of the failure that references Section D.5(a)(i) and has been given a reasonable opportunity to cure the failure.

 (c) If a notice that BNGP has been caused to Withdraw from the Company has been given under Section D.5(a), and the
cooling-off period described in Section D.6 has expired without a rescission of that notice, then: 
 (i) if the Date of Withdrawal
occurs before the First Tranche Investment has been contributed in full, BNGP will pay B&WMR $75,000,000. 
 (ii) if the Date of
Withdrawal occurs after the First Tranche Investment has been contributed in full, BNGP will pay B&WMR $125,000,000. 
 The payment determined under
this Section D.5(c) will be B&WMR’s exclusive remedy for the occurrence of a circumstance described in Section D.5(a). 

D.6 Cooling-Off Period for BNGP & B&WMR. Prior to Termination of the Program or BNGP’s Withdrawal from the Company under
Section D.1, D.2, D.3, D.4 or D.5 (except with 







 
respect to BNGP’s unilateral right to Withdraw under Section D.1(d)), each of B&WMR and BNGP will identify an executive officer who will represent it in connection with this
Section D.6 by written notice to the other party. Those executive representatives will negotiate in good faith to resolve the reason(s) for the proposed Termination of the Program or Withdrawal for a period of not less than 60 days from the
date that BNGP or B&WMR provides notice to the other that it intends to Terminate the Program, or Withdraw, or cause Withdrawal from the Company, as applicable. If the matter is resolved within the 60-day period (or such extended cooling-off
period as may be agreed by the executive representatives), the original notice will be deemed rescinded and of no further effect. If the matter is not resolved within the 60-day period (or such extended cooling-off period as may be agreed by the
executive representatives), the noticed Termination of the Program or Withdrawal from the Company, as applicable, will become effective on the 60th day following the date of the original notice
(or at the end of any agreed extended cooling-off period) (such effective date the “Program Termination Date” or the “Date of Withdrawal”, as applicable). If it is proposed that there be a Termination of the
Program, except as otherwise agreed by B&WMR and BNGP, all activities under the TSAs and Secondment Agreements will cease during the cooling-off period, other than work with respect to a Customer Contract and any related subcontracts and the
minimum amount of work necessary to sustain the Company. If it is proposed that BNGP Withdraw from the Program, except as otherwise agreed by B&WMR and BNGP, all activities under the BPC TSA and Secondment Agreements between BPC and the Company
and BPC and BWNE will cease during the cooling-off period, other than work with respect to a Customer Contract and any related subcontracts. To the extent any work is continued during the cooling-off period, all work will continue consistent with
past practice in the ordinary course. 
 D.7 BPC Release and Discharge. 

(a) Upon Termination of the Program or BNGP’s Withdrawal from the Company, BPC, BDC and BNGP will be released from any obligation to make
any additional investments in the Company under the LLC Agreement. 
 (b) Upon BNGP’s Withdrawal from the Company, each Member and the
Company will, without any further act of any Person, for themselves and on behalf of all present and future Members, be deemed to have released, acquitted, and forever discharged BNGP, BPC, BDC and their Affiliates, and their respective members,
managers, employees, officers, directors, shareholders, and agents (collectively, the “BPC-Affiliated Persons”), of and from any and all Damages with respect to the acts or omissions of BPC-Affiliated Persons in connection with the
LLC Agreement or otherwise in connection with the Program or any Plant, except for (i) obligations of BPC or its Affiliates under EPC Subcontracts and other subcontracts under Customer Contracts (which obligations will be determined by the
terms of each such subcontract) and (ii) the Surviving Provisions of the LLC Agreement and any provisions that expressly survive the termination of other related agreements. Following BNGP’s Withdrawal from the Company, B&WMR and the
Company will indemnify the BPC-Affiliated Persons for any Damages to the extent they relate to or arise out of any Third Party claim with respect to any acts or omissions described in the immediately preceding sentence. The provisions of Article
16 of the LLC Agreement and Section D.12 will apply to any indemnification under this Section D.7(b). 







 (c) Following Termination of the Program or BNGP’s Withdrawal from the Company, B&WMR
and the Company will obtain from (i) any architecture, engineering or contractor firm that is engaged by or on behalf of B&WMR or the Company or any of their respective Affiliates in connection with the Program or any Plant or (ii) a
Customer that will self-perform architecture, engineering or construction services a release and discharge of the BPC-Affiliated Persons of and from any and all Damages with respect to any work product that was provided directly or indirectly by BPC
or any of its Affiliates under the LLC Agreement or the BPC TSA or otherwise (any such work product referred to herein as “BPC Work Product”). The release and discharge required by clause (i) will be obtained not later than the
date on which the architecture, engineering or constructor firm is engaged, or, under clause (ii), the date on which the Customer Contract is executed. 

(d) Following Termination of the Program or BNGP’s Withdrawal from the Company: 

(i) Subject to Section D.7(d)(ii), the Company and B&WMR and their respective Affiliates will not use or include, or permit the
use or inclusion of (including through a sale or other transfer), any BPC Work Product in connection with any Plant or any other project in any jurisdiction that does not have an Acceptable Nuclear Liability Regime. It is understood that BPC Work
Product will not include design or engineering of the NSSS. 
 (ii) If (A) an engineering firm is engaged by or on behalf of the
Company, B&WMR or any of their respective Affiliates to review some or all of the BPC Work Product and to reissue that BPC Work Product as the new engineering firm’s own work product (after making modifications as the new engineering firm
deems appropriate, the reissued work product) (such reissued work product referred to herein, the “Reissued Work Product”); (B) such Reissued Work Product identifies the new engineering firm as the engineer of record and makes
no reference, directly or indirectly, to BPC or any of its Affiliates; and (C) the Company or B&WMR provides documentary evidence substantiating (A) and (B) above to BPC’s reasonable satisfaction, then the Company, B&WMR
and their respective Affiliates may use such Reissued Work Product without restriction at its and their own risk. If B&WMR or its Affiliates engage an engineering firm to prepare the Reissued Work Product, the Company will reimburse B&WMR
for any of its costs and expenses in connection with that engagement prior to using any Reissued Work Product. 
 (iii) BNGP will cease to
be entitled to a Generic Design Fee for Plants the FNTP of which is issued after the Date of Withdrawal absent reconstitution of the Program under Section D.10. 

D.8 Transfer of BNGP’s Interest to B&WMR; Payment. 

(a) Upon BNGP’s Date of Withdrawal under this Exhibit D, BNGP and its Affiliates will immediately lose all rights as a Member and
any rights under the LLC Agreement (including information rights, Board representation or observation rights, loss of any exclusivity rights and other benefits of a Member), except for the right to payment of any amounts due BNGP in accordance with
this Exhibit D and as otherwise provided in Section 17.10 of the LLC Agreement. The effect of BNGP’s Withdrawal from the Company on contracts and other 







 
agreements relating to the Program is addressed in Section D.9. BNGP and any Affiliate of BNGP that holds Membership Interests will transfer to B&WMR or its designee its interests as a
Member of the Company upon any termination of BNGP’s and any of BNGP’s Affiliates’ participation in the Company as a Member simultaneously or in connection with receipt of all amounts due and owing to BNGP or any of its Affiliates
under the LLC Agreement, the BPC TSA or any Secondment Agreement. 
 (b) The payment of any amounts due to BNGP in accordance with this
Exhibit D will be made as soon as reasonably and commercially practicable following BNGP’s Date of Withdrawal and in no event later than 30 days after the Date of Withdrawal, except as provided in Section D.8(c). 

(c) If the Fair Value of BNGP’s Interest is being determined under Section D.11, then B&WMR will pay BNGP $125,000,000 within
30 days after the Date of Withdrawal. The remainder of the withdrawal payment (being the total withdrawal payment less the $125,000,000 already paid) will be paid to BNGP as soon as reasonably and commercially practicable following final
determination of the Fair Value of BNGP’s Interest under Section D.11, but in no event later than 180 days following that determination. If the remainder of the withdrawal payment is not paid within 60 days following the Date of
Withdrawal, the amount outstanding will accrue interest at the following rates, in each case not to exceed the highest per annum interest rate allowed by Applicable Law and subject to the sentence immediately following this sentence: (i) for
the period between 60 and 90 days following the Date of Withdrawal, the Prime Rate plus 3% per annum; (ii) for the period between 90 and 120 days following the Date of Withdrawal, the Prime Rate plus 4% per annum; (iii) for the
period between 120 and 150 days following the Date of Withdrawal, the Prime Rate plus 5% per annum; and (iv) for the period between 150 days following the Date of Withdrawal and the payment of the remainder of the withdrawal payment, the
Prime Rate plus 6% per annum. If the Fair Value of BNGP’s Interest is not determined by the 60th day following the Date of Withdrawal, each of the time periods referenced in the immediately preceding sentence will be delayed day for day
until that determination is made. By way of example, if the Fair Value of BNGP’s Interest is determined on the 75th day following the Date of Withdrawal, the time period in clause (i) above would be the period between 75 and 105 days
following withdrawal. 
 (d) B&WMR may pay the withdrawal payment directly to BNGP or cause the Company to pay the withdrawal payment
as a redemption of BNGP’s interest in the Company. The structure of the payment will not reduce the amounts payable to BNGP in accordance with this Exhibit D, and any alternative consideration other than cash will be approved or
rejected by B&WMR and BNGP in their sole discretion. Any dispute in connection with a payment due to BNGP in accordance with this Exhibit D will be resolved in accordance with Exhibit E.  

D.9 Effect of BNGP’s Withdrawal on Contracts. Except with respect to (i) the obligation to pay all amounts earned and unpaid under
the BPC TSA or any Secondment Agreement and (ii) provisions that expressly survive any termination of the applicable agreement, the BPC TSA, the Secondment Agreements (other than the Secondment Agreement between BWNE and the Company) and the
Cooperation Agreement will automatically terminate on the Date of Withdrawal and be of no further force or effect. BNGP’s Withdrawal from the Company will not affect the obligations of the Members, BNGP or their respective Affiliates








 
under any Customer Contract, any B&W Subcontract, any EPC Subcontract, or any other subcontract under a Customer Contract. Notwithstanding BNGP’s Withdrawal from the Company in
accordance with this Exhibit D or the transfer of all of its Membership Interests in accordance with Article 15 of the LLC Agreement, the Surviving Provisions of the LLC Agreement will survive and continue in full force and effect
with respect to BNGP following the Withdrawal. 
 D.10 Reconstitution & BNGP’s Right to Participate. 

(a) Subject to Section D.10(c), if the Program is Terminated under Sections D.1(a) or D.2(a), and the Program is
revived or continued by the Company (if still controlled by B&WMR or an Affiliate) or by B&WMR or by any of their respective Affiliates before the 10th anniversary of the Program Termination Date, then: 

(i) B&WMR or its Affiliate, as applicable, will provide BNGP with a notice of its intent to revive or continue the Program and, subject
to BNGP executing a confidentiality agreement in a form acceptable to B&WMR, a summary, in reasonable detail, of the plans to reconstitute the Program, its proposed development and deployment schedule, any likely changes in design since the
Program Termination Date, and a preliminary program budget. B&WMR or its Affiliate, as applicable, will provide BNGP with any other information reasonably requested by BNGP in connection with its evaluation of whether to participate in the
reconstituted Program under the Company; and 
 (ii) BNGP will notify B&WMR within 60 days after receipt of the notice and summary
provided to it by B&WMR or its Affiliate, as applicable, and receipt of the information reasonably requested under Section D.10(a)(i) whether it elects to participate in the reconstituted Program. The 60-day review period will commence
once B&WMR has responded with the information reasonably requested by BNGP under Section D.10(a)(i). 
 (b) If BNGP notifies
B&WMR or its Affiliate, as applicable, within the 60-day period that BNGP or its Affiliate elects to participate in the reconstituted Program, then B&WMR or its Affiliate and BNGP will mutually work to
reconstitute the Program and promptly execute and deliver an operating agreement of a jointly owned special purpose Delaware limited liability company (or amend the LLC Agreement, if practicable), with the agreement to contain substantially the same
terms as the LLC Agreement as prior to the Program Termination Date, including with respect to exclusivity, reflecting the changes described in Section D.10(a)(i). 

(c) If (A) BNGP notifies B&WMR or its Affiliate, as applicable, within the 60-day period provided in Section D.10(a)(ii) that
it elects not to participate in the continued development and deployment of the Program, or (B) BNGP fails to provide notice of any decision whether to elect to participate in a reconstituted Program within that 60-day period, or (C) in
the case where BNGP Withdraws from the Company under Section D.2, BNGP does not agree to invest an amount equal to the payment received by BNGP under Section D.2(b) in the reconstituted Program as part of the reconstitution, then
B&WMR or its Affiliate may develop and deploy the Program without BNGP, BPC, BDC, or any of their Affiliates. 







 D.11 Determination of Fair Value of BNGP’s Interest. 

(a) If (i) BNGP Withdraws from the Company under Section D.3(a) or Section D.4(a), and (ii) the First Tranche Investment
has been contributed in full, and (iii) BNGP has not provided B&WMR an irrevocable written statement that it has elected to receive the fixed $125,000,000 withdrawal payment under Section D.3(c)(ii)(2) or Section
D.4(c)(ii)(2), as applicable, in lieu of a determination of the Fair Value of BNGP’s Interest under this Section D.11, then immediately following the Date of Withdrawal, BWNE’s and BDC’s respective Chief Financial Officers
or equivalent senior executives will work for 30 days in good faith to mutually agree on the Fair Market Value of the Company as of the Date of Withdrawal (the “Valuation Date”). If BWNE and BDC executives fail to reach an agreement
on the Fair Market Value of the Company as of the Valuation Date during their 30-day determination period (or such longer period as may be agreed by the Chief Financial Officers), B&WMR will select and identify to BNGP an Appraiser (the
“First Appraiser”) and BNGP will select and identify to B&WMR an Appraiser (the “Second Appraiser”) no later than 10 days after the end of the determination period. The date when both Appraisers have been
identified and retained will be the “Start Date.” B&WMR and BNGP will cooperate, and cause their Affiliates to cooperate, with any Appraisers appointed under this Section D.11 and share with each Appraiser all
information relevant to a valuation of the Company as of the Valuation Date, including that information described in Section D.11(c), and subject to the confidentiality restrictions in Section D.11(c). On or before the 20th
day after the Start Date, the First Appraiser and the Second Appraiser will each determine its preliminary view of the Fair Market Value of the Company in accordance with the criteria set forth in the definitions of those terms in the LLC Agreement,
and will consult with each other with respect to their respective preliminary values. On or prior to the 60th day after the Start Date, the First Appraiser and the Second Appraiser will each render to BWNE and BDC their written reports on the Fair
Market Value of the Company. 
 (b) If the higher Fair Market Value determined under Section D.11(a) (the “High
Value”) is not more than 115% of the lower Fair Market Value determined under Section D.11(a) (the “Low Value”), then the Fair Market Value will be the average of the High Value and the Low Value. If the High
Value is more than 115% of the Low Value, then, not more than 15 days after the reports, the First Appraiser and the Second Appraiser will together designate a third Appraiser that is independent from B&WMR, BNGP and their respective Affiliates
(the “Third Appraiser”). The Third Appraiser will not, as of the time of selection, be engaged by, or on behalf of, either B&WMR, BNGP or any of their respective Affiliates, or have previously been engaged by or on behalf of the
either B&WMR or BNGP within the last 36 months unless expressly disclosed to and approved by B&WMR or BNGP, as applicable, such approval not to be unreasonably withheld. The Third Appraiser will make a determination of the Fair Market Value
of the Company and deliver its written report to BWNE and BNGP (the “Third Value”) not more than 30 days after the Third Appraiser is designated. If the Third Value is within the middle one-third of the range of values between the
High Value and the Low Value (the “Mid-Range”), then the Fair Market Value will be the Third Value. If the Third Value does not fall within the Mid-Range, then the Fair Market Value will be the average of (i) the Third Value
and (ii) either (A) the High Value or (B) the Low Value, whichever is closest to the Third Value. In no event will the Fair Market Value be less than the Low Value nor greater than the High Value. The determination of the Fair Market
Value under this Section D.11(b) will be final and binding on B&WMR and BNGP and their respective Affiliates. 







 (c) Promptly following the engagement of each Appraiser under this Section D.11, each
Appraiser will enter into a nondisclosure agreement with B&WMR, the Company and BNGP. B&WMR, the Company and BNGP will provide each Appraiser with written instructions regarding the preparation of its determination of the Fair Market Value
of the Company, including a copy of the pertinent provisions of the LLC Agreement. The Company will provide each Appraiser with (i) the Company’s most recent consolidated financial statements, (ii) the most recent financial forecast
for the Company and, if before the Design Completion Date, the Development Budget, (iii) a management presentation with respect to the matters set forth in clauses (i) and (ii), and (iv) such other relevant information reasonably
requested by an Appraiser for the determination of Fair Market Value. Each Appraiser will receive identical information under this Section D.11(c), except that the Third Appraiser will also receive copies of the written reports of the First
Appraiser and the Second Appraiser described in Section D.11(a). 
 (d) All fees, expenses and disbursements of each Appraiser will
be the responsibility of the party that engaged that Appraiser. All fees, expenses and disbursements of the Third Appraiser will be shared equally by B&WMR and BNGP. 

(e) The “Fair Value of BNGP’s Interest” to be paid to BNGP in connection with BNGP’s Withdrawal from the Company
under Section D.3(a) or Section D.4(a), if required under Section D.3(c)(ii)(1) or Section D.4(c)(ii)(1), is the amount equal to the sum of (i) the Capital Account of BNGP, plus (ii) the product of
(x) BNGP’s Share in the Company multiplied by (y) the difference between (A) the total value of the Company as determined under this Section D.11 minus (B) the total Capital Accounts of all members in the
Company. This amount will be paid in accordance with Section D.8. 
 D.12 Indemnification Provisions for BPC-Affiliated
Persons. Promptly after receipt by a BPC-Affiliated Person entitled to indemnification under Section D.7(b) of any claim or notice of the commencement of any action, administrative or legal proceeding, or investigation as to which any
indemnity provided for in Section D.7(b) may apply, the BPC-Affiliated Person will notify B&WMR and the Company in writing of that fact, which will include, to the extent known, the facts constituting the basis for the claim. B&WMR or
the Company may, upon written notice to the BPC-Affiliated Person, assume the defense thereof with counsel designated by B&WMR or the Company and reasonably satisfactory to the BPC-Affiliated Person. Notwithstanding the preceding sentence,
neither B&WMR nor the Company will be entitled to assume control of the defense of any claim if, in the BPC-Affiliated Person’s good faith judgment: (1) it is advisable for the BPC-Affiliated Person to be represented by separate counsel
because a conflict or potential conflict exists between either B&WMR or the Company and the BPC-Affiliated Person; (2) there are defenses that are available to the BPC-Affiliated Person that are likely to conflict with those available to
B&WMR or the Company; or (3) the claim involves the potential imposition of a criminal or quasi criminal liability on the BPC-Affiliated Person or the remedy sought in the claim is an injunction, restraining order, declaratory relief or other
non-monetary relief against the BPC-Affiliated Person that is separate and distinct from any similar liability asserted with respect to B&WMR or the Company. If B&WMR or the Company is not entitled to assume the defense of a claim, the
BPC-Affiliated Person will be entitled to control and assume responsibility for the defense of the claim at the cost and expense of B&WMR and the Company (to the extent such costs and expenses are reasonable). During the pendency of








 
any matter to which any indemnity provided in Section D.7(b) may apply, the BPC-Affiliated Person will retain authority to approve any and all communications with, and to prevent the
submission of any documents to, any Governmental Authority having jurisdiction over the matter, except as otherwise required by Applicable Law, except that the BPC-Affiliated Person will be responsible for any additional delay or incremental costs
associated with this review. Without the prior written consent of the BPC-Affiliated Person, neither B&WMR nor the Company will enter into any settlement of any claim for Damages which would lead to
liability, impose injunctive or other equitable relief or would create any financial or other obligation on the part of the BPC-Affiliated Person. B&WMR or the Company may accept any settlement without the
consent of the BPC-Affiliated Person if the settlement imposes no obligation on a BPC-Affiliated Person and the settlement provides a complete release to the BPC-Affiliated Person and no requirement that the BPC-Affiliated Person acknowledge fault
or culpability. Each Party will cooperate in the defense of any claim and will furnish such records, information and testimony as may be reasonably requested in connection therewith, in each case at the expense of B&WMR and the Company (to the
extent the expenses are reasonable). 
 D.13 B&WMR Right to Cause Withdrawal of Other Members. 

(a) Except as otherwise expressly provided in a Member’s Subscription Agreement or Joinder Agreement, B&WMR has the right to cause
any Member other than B&WMR or BNGP (the “Other Member”) to Withdraw from the Company in accordance with this Section D.13. 

(b) If the Program is Terminated under Section D.1(a) or Section D.2(a), the Other Member’s rights as a Member and under
the LLC Agreement will immediately cease, the Other Member will be considered to have Withdrawn from the Company, and its Membership Interests will be automatically and immediately forfeited to the Company, without any action on the part of the
Company or the Other Member. 
 (c) Except as otherwise provided in a Member’s Subscription Agreement or Joinder Agreement, if there
has been: 
 (i) a material breach of a material provision of the LLC Agreement by an Other Member or any of its Affiliates, or a material
breach of a material provision of any agreement between the Other Member or any of its Affiliates on the one hand, and the Company or any subcontractor to the Company on the other hand, after that Other Member has received notice of that breach and
has been given a reasonable opportunity to cure that breach; or 
 (ii) a Change of Control of any Other Member or an Affiliate of the
Other Member that results in direct or indirect control of that Other Member or its Affiliate by a Person (or an Affiliate of that Person) that is a B&WMR Competitor or a BPC Competitor, or that poses a Reputational Risk to the Company, the
Program, B&WMR, BNGP or their respective Affiliates, 
 then the Other Member and its Affiliates will immediately lose all rights as a Member and any
rights under the LLC Agreement (including information rights, Board representation or observation rights, loss of any exclusivity rights and other benefits of a Member), except that the Member will retain the economic interest represented by its
Membership Interest as an assignee (as such term is used in Section 18-702 of the Act). 







 (d) In addition, if there has been a breach or a Change of Control described in Section
D.13(c), the Other Member who breached or that underwent a Change of Control (or a Member who had an Affiliate that breached or that underwent a Change of Control) will immediately make the payment and take the actions as may be set forth in
that Member’s Subscription Agreement or Joinder Agreement, as applicable. 
 (e) Unless otherwise expressly set forth in the
applicable agreement, the Withdrawal from the Company by the Other Member does not, in and by itself, terminate any agreement between the Other Member or any of its Affiliates on the one hand, and the Company or any subcontractor to the Company on
the other hand, other than the LLC Agreement. 
 D.14 Exclusive Remedy and Sole Liability. 

(a) Except as otherwise set forth in this Exhibit D, if any Member Withdraws from the Company, no Member or the Company will be
obligated to make any payment to any other Member or the Company based on the Termination of the Program or the withdrawing Member’s Withdrawal from the Company. Each Member expressly disclaims any right to seek Damages from the other Members
or the Company based on the Termination of the Program or the withdrawing Member’s Withdrawal from the Company. 
 (b) If a Member
Withdraws from the Company under this Exhibit D, the provisions of this Exhibit D are the exclusive remedy to that Member for any breach of the LLC Agreement that occurred prior to the Date of Withdrawal (other than breaches of
Exhibit F that were not known to that Member on that Date of Withdrawal). Following a breach or default by a Member that triggers withdrawal rights under this Exhibit D, that Member will not be deemed to continue to be in default or
breach so long as it remains in compliance with the provisions of this Exhibit D. 
 [End of Exhibit D] 







 EXHIBIT E 

DISPUTE RESOLUTION 

In accordance with Section 17.1 of the Generation mPower Limited Liability Company Agreement, dated February 28, 2011 (the
“LLC Agreement”) to which this Exhibit is attached, Disputes will be addressed in accordance with this Exhibit E. Capitalized terms used and not defined in this Exhibit have the meanings given to those terms in the LLC
Agreement. References to “Sections” mans sections of this Exhibit, unless otherwise specified. 
 E.1 General Intent of the
Parties. Any and all claims, counterclaims, demands, causes of action, controversies or disputes between or among (i) the Company, (ii) a Member or its Affiliates and (iii) another Member (or Members) or their Affiliates relating
to the Company or the Program (such parties, the “Dispute Parties”) arising out of or in any way relating to the LLC Agreement, the TSAs, or any Secondment Agreement or any other agreement that expressly references this Exhibit
E for resolution of any disputes between the parties thereto (the “Subject Agreements”) (but not the Guarantees or any Customer Contract, EPC Subcontract or B&W Subcontract if the disputed matter involves the Customer) (each
a “Dispute”) will be addressed in accordance with the procedures of this Exhibit E. Any Dispute Party may seek a preliminary injunction or other provisional judicial remedy if the action is necessary to prevent
irreparable harm or preserve the status quo, in which case the Dispute Parties nonetheless will continue to pursue resolution of the Dispute by means of the procedure set forth in this Exhibit E. 

E.2 Management Negotiations. 

(a) If a Dispute is not resolved in the normal course of business, the Dispute Parties will attempt in good faith to resolve the Dispute
promptly by negotiation between executives who have authority to settle the controversy utilizing the following procedure. Any Dispute Party may give the other Dispute Parties written notice of the existence of a Dispute. Within 30 days after
delivery of the notice, the Dispute Party receiving the notice will submit to the disputing Dispute Party a written response (the date such response is deemed received pursuant to the notice provisions of the applicable Subject Agreement, the
“Response Date”). The notice and the response will include (i) a statement of the Dispute Party’s position and a summary of arguments supporting that position and (ii) the name and title of the executive who will
represent the Dispute Party in the negotiations (the “Executive(s)”) and the name and title of any other Person who will accompany the executive. 

(b) Within 10 Business Days of the Response Date, the Executives will establish a mutually acceptable location and date, which date will not
be greater than 20 Business Days from the Response Date, to meet. After the initial meeting date, the Executives will meet or otherwise confer, as often and in accordance with such schedule as they reasonably deem necessary, to attempt to resolve
the Dispute. All reasonable requests for information made by the Dispute Parties to each other will be honored. 
 (c) All communication
and writing exchanged between the Dispute Parties related to the exchanges and discussions under this Section E.2 are for settlement purposes only and are confidential and will be deemed to be settlement negotiations and subject to Rule 408
of the Federal Rules of Evidence and any similar applicable state law or rule and will not be used or referred to in any subsequent binding adjudicatory process between the Dispute Parties. 







 E.3 Mediation. If a Dispute is not resolved within 60 days of the Response Date, or if the
Dispute Party receiving a notice or a response pursuant to Section E.2(a), refuses to or does not meet within the 60-day period, except as such deadline may be extended by agreement between the Executives, then any Dispute Party may initiate
