Members and the Company. Alcoa will advise the Alumina Members of all available positions within the Company for which the applicable Alumina Member has indicated that it may have qualified candidates. Alcoa will determine if the Alumina

amounts. The Company shall reimburse each provider for the actual amount of all payments of salaries, bonuses, retirement allowances, the employer’s portion of social security payments and other payments made by such provider with respect
to each employee seconded by it, provided that such amounts are consistent with the then applicable rules and regulations regarding compensation for seconded employees established by the Company. Such reimbursements shall be made on a monthly

OWNERSHIP INTEREST TRANSFER RESTRICTIONS 

Section 9.1 General Restrictions on Transfer. 

(a) Transfers Other Than to Affiliates of Members. Except as otherwise provided in Section 9.1(b) (relating to permitted transfers to
Affiliates of Members), no Member may sell, transfer or assign (hereinafter in this Article IX referred to interchangeably as “Transfer”) to any individual or entity (each a “Transferee”) all or any portion
of an Interest (including, without limitation, any interest in Company capital, income, gain, loss, deduction or credit, or any items thereof) unless (i) such Transfer is expressly permitted under this Article IX, and (ii) such Transferee
first executes an instrument reasonably satisfactory to the Board, accepting and agreeing to all of the terms and conditions of this Agreement (including specifically, without limitation, this Article IX), including a counterpart signature
page to this Agreement. The Transferee of a Transfer of all or any portion of an Interest that satisfies all of the foregoing requirements of this Subsection (a) or all of the requirements of Section 9.1(b) shall be admitted as a Member
of the Company effective immediately prior to the effective time of such Transfer; if the Member who made such Transfer assigned its entire Interest, such Member shall cease to be a member of the Company immediately following such admission; and the

 (b) Transfers to Affiliates of Members. Notwithstanding the provisions of Section 9.1(a), any
Member may, without the consent of any other Members, and without first making any Offer to other Members as described in Section 9.3(b) hereof, Transfer all or any portion of such Member’s Interest to an Affiliate of such Member,
provided, however, that (i) such Affiliate must satisfy all of the requirements of Section 9.1(a) that are applicable to Transfers to Transferees that are not Affiliates of Members; and (ii) no such Transfer to such Affiliate shall be
permitted under this Section 9.1(b) if such Transfer would result in the transferring Member’s breaching the provisions of Section 9.3(a) hereof (relating to the 21% Limitation) with respect to any portion of the Interest the
transferring Member desires to Transfer to such Affiliate. If all of the foregoing requirements of this Section 9.1(b) are satisfied, such Affiliate shall be admitted as a Member of the Company in accordance with the provisions of Section
9.1(a). 
 Section 9.2 Permissible Transfers by the Alcoa Members. 

(a) Passive Investor. Notwithstanding the provisions of Section 9.1(a) and Section 9.2(b), but specifically subject to the provisions of

any Offer to the other Members as described in Section 9.3(b). Such investor shall only receive business information about the Company that is required by the law governing the Company, as reflected in this Agreement, plus additional
information as is believed reasonable by the Alcoa Members as being appropriate for the particular investor and consented to by the Alumina Members, which consent may be withheld in their sole discretion. Said investor shall be entitled to
share in the distributions of the Company in proportion to its Percentage Interest in the Company. The applicable Alcoa Member(s) shall give not less than thirty (30) days prior written notice to the Alumina Members of their intent to so
Transfer such part of their Interests, and upon such Transfer, the investor shall be admitted as a Member of the Company in accordance with the provisions of Section 9.1(a). 

(b) Active Investor. Notwithstanding the provisions of Section 9.1(a), but specifically subject to the provisions of Section 9.3(a)
(relating to the 21% Limitation), if, at any time during the term of this Agreement, one or more of the Alcoa Members desires to Transfer a portion of their Interest that is a nine percent (9%) or less Percentage Interest in the Company to an
investor, such Alcoa Member(s) must first obtain the consents of the Alumina Members to such Transfer, which consents shall not be unreasonably withheld, but such Alcoa Member(s) shall not be required to make any Offer to other Members as described
in Section 9.3(b), and none of the Alumina Members shall have any right pursuant to Section 9.3 to purchase any part of such portion of the Interest of such Alcoa Members. The applicable Alcoa Members shall specify a time and a place of
closing not less than ten (10) nor more than twenty (20) business days following the date of consent by each of the Alumina Members, whichever is latest, and such Alcoa Members shall deliver to such investor at the closing all requisite and duly
executed forms of transfer against payment for the portion of the Interest being Transferred. At the closing, the investor shall be admitted as a Member of the Company in accordance with the provisions of Section 9.1(a) hereof.

Transferred by the Alcoa Members, individually and collectively, during the entire term of this Agreement under both Section 9.2(a) and Section 9.2(b) shall not exceed a nine percent (9%) Percentage Interest in the Company.

 Section 9.3 21% Limitation: Offers to Other Members. 

(a) 21% Limitation. Notwithstanding (i) any of the foregoing provisions of this Article IX, (ii) any other provisions of this Agreement, or
(iii) any provisions contained in any other agreement, document or instrument (whether or not incorporated or referred to in this Agreement), at all times during the term of this Agreement, Interests of the Members that, in the aggregate, represent
not less than twenty-one percent (21%) of all Percentage Interests in the Company at each such time may not be Transferred to any individual or entity (including, without limitation, any Transfer to an Affiliate of any member as described in
Section 9.1(b)) without the prior written consent of all Members (the “21% Limitation”). The 21% Limitation shall be applied in the following manner: 

 

	 	(i)	Except as otherwise provided in Clause (iii) or (iv) of this Section 9.3(a), from and after the execution of this Agreement and until an aggregate seventy-nine percent (79%) Percentage Interest in the Company has
been Transferred, the 21% Limitation shall not apply to any Transfer, but from and after the first time at which an aggregate seventy-nine (79%) Percentage Interest has been so Transferred, all subsequent Transfers of all or any portion of any
Interest in the Company shall require the prior written consent of all Members; provided, however, that no such consent to any such subsequent Transfer by any Member that acquired a nine percent (9%) or less Percentage Interest in the Company
pursuant to Section 9.2(a) and/or Section 9.2(b) shall be required with respect to the Interest so acquired by such Member pursuant to Section 9.2 (but shall be required with respect to any other Interest in the Company held by such
Member), and any reference in this Article IX to the prior written consent of all Members under this Section 9.3(a) shall be deemed not to require the consent of such Member with respect to the Interest it acquired pursuant to Section
9.2 hereof. 

  

	 	(ii)	As among the current Members of the Company, the overall 21% Limitation shall initially be composed of the following Percentage Interests now held by the current Members (each a “Designated Percentage
Interest”): 

  

	 	(A)	a fourteen percent (14%) Percentage Interest in the case of Alumina USA (so that the remaining twenty-six percent (26%) Percentage Interest of the Alumina Members in the aggregate is not a Designated Percentage
Interest); and 

  

	 	(B)	a seven percent (7%) Percentage Interest in the case of Alcoa USA (so that the remaining fifty-three percent (53%) Percentage Interest of the Alcoa Members in the aggregate is not a Designated Percentage Interest);



  
 16 









	 	(C)	Notwithstanding the provisions of Clause (i) of this Section 9.3(a), if at any time during the term of this Agreement the Percentage Interest of Alumina USA or the Percentage Interest of Alcoa USA is reduced to a
percentage less than the Designated Percentage Interest of Alumina USA or Alcoa USA, as the case may be, as a result of adjustments made to the Capital Accounts of the Members pursuant to the Tax Protocol or for any other reason (other than (A) a
Transfer by Alumina USA or Alcoa USA, as the case may be, of all or a portion of its Designated Percentage Interest with the prior written consent of all Members pursuant to this Section 9.3(a); or (B) the admission to the Company of any new
Member, other than as the result of a Transfer of all or a portion of any Member’s Interest, as described in Clause (iv) of this Section 9.3(a) below), no subsequent Transfer of any Interest or portion of any Interest shall be permitted
without the prior written consent of all Members unless, prior to such Transfer, all or any required portion of the Percentage Interest held at such time by any other Member or Members is designated in a writing signed by all of the Members as a
replacement Designated Percentage Interest (each a “Replacement Designated Percentage Interest”) to the extent necessary to bring the aggregate of all Designated Percentage Interests back to not less than twenty-one percent (21%).


  

	 	(iii)	Notwithstanding any other provision of this Agreement or any provision of any other agreement, document or instrument (whether or not incorporated or referred to in this Agreement), no new Member (a “Potential
Member”), including, without limitation, any Affiliate of a Member, shall be admitted to the Company as a Member (other than as a result of a Transfer of an Interest or portion of an Interest that is permitted under any of the foregoing
provisions of this Article IX) if the effect of the admission of such Potential Member would be to reduce the aggregate of all Designated Percentage Interests to less than twenty-one percent (21%), unless, prior to the admission of such
Potential Member, one or more Replacement Designated Percentage Interests are designated in a writing signed by all Members and by the Potential Member to the extent necessary to maintain the aggregate of all Designated Percentage Interests at not
less than twenty-one percent (21%). 

  

	 	(iv)	In the event of a Transfer of all or any portion of a Designated Percentage Interest pursuant to, and in accordance with, any of the foregoing provisions of this Article IX, such Designated Percentage Interest,
or the portion thereof so Transferred, shall remain a Designated Percentage Interest in the hands of the Transferee thereof for all purposes of this Article IX, and any subsequent Transfer of, or reduction in the size of, such Designated
Percentage Interest or any portion thereof by such Transferee (or any successors Transferee) shall trigger the application of the relevant foregoing provisions of this Section 9.3(a). 


  
 17 









	 	(v)	The Transfer of all or any portion of a Designated Percentage Interest with the prior written consent of all Members pursuant to the foregoing provisions of this Section 9.3(a) shall, nevertheless, also be
subject to the Offer requirements of Section 9.3(b). 

  

	 	(vi)	In the event any Member’s Percentage Interest shall, at any time during the term of this Agreement, exceed such Member’s share, expressed as a percentage, of Company capital, income, gain, loss, deduction or
credit within the meaning of Section 5.02(2) of Revenue Procedure 95-10, 1995-3 Internal Revenue Bulletin 20, the lowest percentage share of such Member in any item of Company capital, income, gain, loss, deduction or credit shall be deemed to be
such Member’s Percentage Interest solely for purposes of the 21% Limitation set forth in the first sentence of this Section 9.3(a). 


(b) Offers to the Other Members. Except as otherwise provided in Section 9.1(b) or Section 9.2, if at any time during the term of
this Agreement any Member desires to Transfer all or any portion of its Interest (including without limitation, the Transfer of all or any portion of a Designated Percentage Interest with the prior written consent of the requisite Members pursuant
to Section 9.3(a)), such Member shall first make an offer in writing delivered to all of the other Members (an “Offer”) to sell such Interest or portion thereof to the other Members in accordance with the provisions of
Section 9.4 and 9.5 hereof. For purposes of this Section 9.3(b) and Section 9.4 and 9.5, so long as any of the Alcoa Members has any Interest and any of the Alumina Members also has any Interest, the aggregate Interests of the
Alcoa Members shall be treated as a single Member unit (the “Alcoa Unit”) and the aggregate Interests of the Alumina Members shall likewise be treated as a single Member unit (the “Alumina Unit”), and any offers
with respect to the Alcoa Unit or any portion thereof shall be made to and may be accepted by only the Alumina Unit, and likewise any Offers with respect to the Alumina Unit or any portion thereof shall be made to and may be accepted by only the
Alcoa Unit. 
 Section 9.4 Options. For a period of forty-five (45) days from and after the receipt of an
Offer from any Member (the “Transferring Member”), each of the other Members (each a “Purchasing Member”) shall have the option (each an “Option”) either to: (a) purchase (either directly or by
an Affiliate of the Purchasing Member) its pro rata share of the Transferring Member’s Interest available for sale based upon such Purchasing Member’s then current Percentage Interest in the Company (excluding the Transferring
Member’s Percentage Interest) upon the same terms and conditions as specified in the Offer; or (b) decline to purchase the Transferring Member’s Interest so available, in which case the remaining Member may purchase said Interest. During
the foregoing forty-five (45) day period, the Transferring Member shall furnish to all other Members such further evidence as they may reasonably require to enable them to establish the bona fides of the Offer. 

Section 9.5 Election of Options. 
 (a) Purchase
by Other Member(s). If any Purchasing Member elects to purchase its share of the Transferring Member’s Interest available for sale pursuant to Section 9.4(a) hereof: (i) such Purchasing Member shall specify a time and a
place of closing not less than ten (10) nor more than sixty (60) business days following the mailing of the notice of exercise of the Option to purchase or at such later time as agreed to by the Transferring Member and such Purchasing Member; and
(ii) the Transferring Member shall deliver to the Purchasing Member, or to its 

  
 18 








 
designee (which must be an Affiliate of the Purchasing Member), at the closing all requisite and duly executed forms of transfer against payment for the Transferring Member’s Interest being
sold upon the same terms as set forth in the Offer. At the closing, the designee of such Purchasing Member(s), if any has been designated, shall be admitted as a Member of the Company simultaneously with the Transfer by the Transferring Member
of its Interest available for sale, and upon a Transfer by the Transferring Member of its entire Interest, the Transferring Member shall cease to be a member of the Company. 

(b) Election Not to Purchase. If the Purchasing Members do not exercise their respective Options to purchase all of the Transferring Member’s
Interest that is the subject of the Offer pursuant to Section 9.5(a) or fail to elect any Option granted in Section 9.4 within the said forty-five (45) day period, then the Transferring Member may sell its Interest that is the subject
of the Offer to a third party upon the same or more stringent terms and conditions as specified in the Offer, provided that the prospective purchaser is not a Competitor of any Purchasing Member; provided, however, that the prospective
purchaser, concurrently with such sale, agrees in a written undertaking, in form and substance reasonably acceptable to the Board, to be bound by the terms of this Agreement and the Charter and to be a party to this Agreement in place of the
Transferring Member. The closing of the sale to a third party must take place within sixty (60) days of the expiration of the aforementioned forty-five day (45) period. If the prospective purchaser is a Competitor of any Purchasing Member,
the Transferring Member shall only be entitled to sell its Interest to the Competitor if all of the Purchasing Members consent to the sale of the Transferring Member’s Interest upon the terms and conditions specified in the Offer, which consent
the Purchasing Members may withhold in their sole discretion. In the event the Purchasing Members consent to the sale of the Transferring Member’s Interest as provided in this Section 9.5(b), the prospective purchaser shall be
admitted as a Member of the Company simultaneously with the Transfer by the Transferring Member of its Interest, and upon a transfer by the Transferring Member of its entire Interest, the Transferring Member shall cease to be a Member of the
Company. If any Purchasing Member withholds consent to the sale of the Transferring Member’s Interest to a Competitor, then the Transferring Member shall not sell its Interest to such Competitor, and the Purchasing Members shall not be
liable to the Transferring Member for any liability incurred by the Transferring Member in connection with the Offer. 
 If the Transferring Member does not
sell its Interest as provided in this Section 9.5, the Transferring Member’s Interest shall not be free from the restrictions contained in this Article IX, and such Transferring Member’s Interest shall not thereafter be sold
unless the provisions of this Article IX shall again be complied with. 
 Section 9.6 Other Restrictions. In addition to the
restrictions on transfers contained in this Article IX, any direct or indirect transfer restrictions contained in the Charter and the May 1995 Letter Agreement, and applicable to the Company, are incorporated for the benefit of the Members by
reference into this Agreement. 
 Section 9.7 Recognition by Company of Transfers. No Transfer, or any part thereof, that
is in violation of this Article IX shall be valid or effective, and the Company, the Members and the Board shall not recognize the same for the purpose of making any distributions to Members with respect to such Interest or part thereof. The
Company, the nontransferring Members and the Board shall incur no liability as a result of refusing to make any such distributions to the Transferee of any such invalid Transfer.

 Section 14.5 Winding Up. As outlined in the Tax
Protocol, upon the occurrence of a Liquidating Event, the Company shall continue solely for the purposes of winding up its affairs in an orderly manner, liquidating its assets, and satisfying the claims of its creditors and Members, and no Member
shall take any action that is inconsistent with, or not necessary to or appropriate for, the winding up of the Company’s business and affairs. To the extent not inconsistent with the foregoing, all covenants and obligations in this
Agreement shall continue in full force and effect until such time as the Property has been distributed pursuant to this Section 14.5 and the Company’s Certificate has been canceled in accordance with the Act. All of the business and
affairs of the Company shall be liquidated and wound up and all of its assets shall be distributed by the liquidating trustee as follows: 
 (a) First, to
the creditors of the Company (other than Members who are creditors) in satisfaction of the debts and liabilities of the Company (whether by payment or the making of reasonable provision for payment thereof); 

(b) Second, to Members that are creditors of the Company in satisfaction of the debts and liabilities of the Company (whether by payment or the making of
reasonable provision for payment thereof); and 
 (c) At Alcoa USA’s option, the Capital Accounts of the Alumina Members may be liquidated in
cash. If Alcoa USA so elects, Alcoa USA may make an additional cash capital contribution upon liquidation sufficient so that, if such funds are distributed to the Alumina Members, their aggregate Capital Account balances will be reduced to
zero. Cash payments shall be made to the extent necessary to ensure that the Alumina Members receive their aggregate Percentage Interest of the total value of all assets distributed upon liquidation as determined in accordance with Section
14.4. For convenience, such additional capital contribution and distributions may, at Alcoa USA’s election, be effected by direct payments from Alcoa USA to the Alumina Members. The provisions of this Section 14.5(c) shall be
applied only after giving full effect to all distributions pursuant to Sections 5.1 and 7.1 of the Tax Protocol. 
 (d) All remaining assets of the Company
shall be distributed in kind to those Members that contributed such in-kind assets in proportion to their respective Capital Account balances.

 ANNEX A 

ENTERPRISE COMPANY INFORMATION 
 Unless
expressly defined in this Agreement, capitalized terms used in this Annex A have the meanings given in the Charter. 
  

	1.	The Foundation Members shall each have access during normal business hours, upon reasonable advance notice (with the intention that the Company will provide access within 28 days of receiving such notice), to all
information, produced or held by the Company, including all information produced or held by Alcoa or Related Bodies Corporate of Alcoa acting in the capacity of AWAC Manager of the Enterprise and the Company. Such information will be produced
and held jointly on behalf of the Company and the Foundation Members, and will be freely available to each of them subject to and in accordance with these terms. Such information rights are without prejudice to, and in no way limit the
Members’ respective rights to access information regarding the Company under this Agreement or at law (“General Information Rights”). For the avoidance of doubt, this Annex A does not apply to any information relating to
any businesses or interests held by a Foundation Member or its Affiliates that are not part of the Enterprise. 

  

	2.	Each Foundation Member shall have reasonable access to the head of each Business Unit within the Enterprise through the Member’s Strategic Council members and other nominated representatives. 


 

	3.	Notwithstanding anything to the contrary in this Annex A, the Company and each of the Foundation Members and its Related Bodies Corporate shall not be required to (a) violate any legal requirements (including with
respect to employee data privacy laws) or any obligation of confidentiality to any third parties, or (b) provide access to or disclose information where such access or disclosure would jeopardize the attorney-client privilege of such entity. Any
access to or provision of information pursuant to this Annex A shall be conducted in such a manner as not to interfere unreasonably with the operation of the Enterprise or any Enterprise Company; provided, that this sentence shall not derogate from
the rights to information set out in this Annex A. 

  

	4.	In addition, notwithstanding anything to the contrary in this Annex A, with respect to a request by a Foundation Member that is not the AWAC Manager or a Related Body Corporate of the AWAC Manager (a
“Non-Manager Member”) that relates to any Company customer sales contract (“Customer Contracts”): 

  

	 	(a)	that access right shall be limited to two employees of the Non-Manager Member who shall be nominated by the Non-Manager Member; 

  

	 	(b)	such Customer Contracts shall be kept strictly confidential and may not be disclosed by them to other personnel or representatives of the Non-Manager Member except for the purposes of enforcing legal rights of the
Enterprise or obtaining legal advice in connection with such enforcement, and the AWAC Manager or an Enterprise Company may require such employees to sign customary and appropriate confidentiality undertakings; 


  
 A-1 









	 	(c)	the AWAC Manager or the Company may provide access to Customer Contracts by means of an electronic data room or other protocol designed to preserve confidentiality; 


 

	 	(d)	upon the occurrence of a Change of Control with respect to the Non-Manager Member, all rights of Non-Manager Member or any of its nominated employees to access or receive Customer Contracts shall terminate, and they
shall return or destroy any Customer Contracts previously provided to them; and 

  

	 	(e)	in the event that Customer Contracts cannot be disclosed due to an obligation of confidentiality to any third parties, the Company and AWAC Manager will use their commercially reasonable efforts to seek a waiver of such
confidentiality obligations or to otherwise permit such disclosure. 

  

	5.	The AWAC Manager shall adopt reasonable protocols to ensure that only those employees of the AWAC Manager that are engaged in the day-to-day operations and management of the Company will be entitled to receive Customer
Contracts and only to the extent that is reasonably necessary for the management and operation of the Company. 

  

	6.	Prior to providing access to any information under this Annex A, but without in any way restricting any General Information Rights, the Company may require a Foundation Member to provide a customary and appropriate
undertaking containing confidentiality and use restrictions consistent with this Annex A and (without limitation) allowing (a) use of such information in connection with its investment in the Enterprise and the operation of the Enterprise’s
business and (b) disclosure to the extent required by law. Each Foundation Member shall take reasonable measures to ensure that its access to Company information is consistent with applicable laws, including competition laws. 


 

	7.	Each Non-Manager Member will receive prompt notice of events known to the AWAC Manager which may affect the earnings or dividends of the Company or which may lead to a significant change in the amount of leveraging
within the Company. 

  

	8.	The Company will prepare annual operating plans and capital budgets (or follow such other planning/budgeting process, if any, that may be used by the AWAC Manager from time to time). The AWAC Manager will keep the
Non-Manager Member informed of the progress in formulating any such plans and budgets and will specifically advise the Non- Manager Member if the consolidated effect of any such plans and budgets appears likely to require any equity call from the
Non-Manager Member in the year for which the plans and budgets are being prepared. Any such operating plans and capital budgets will be approved by Members holding a majority of the Percentage Interests. 


 

	9.	Any individual Request for Authorization for more than US $10 million relating to the Company shall be sent for information to the Foundation Members at the same time it is submitted to the AWAC Manager.



  
 A-2 









	10.	Despite any other provision of this Annex A, the AWAC Manager is not required to provide any notice, advice or information to a Foundation Member if such notice, advice or information has already been provided by the
AWAC Manager to that Member or any of its Related Bodies Corporate. 

  

	11.	In the event of a proposed or anticipated Change of Control of the Ultimate Holding Company of a Foundation Member, the other agrees to provide commercially reasonable cooperation, at the expense of the Members whose
Ultimate Holding Company is undergoing the Change of Control, with respect to (a) filings and notifications with any governmental authority that reasonably may be necessary, proper or advisable under the relevant competition laws to consummate and
make effective the proposed acquisition; and (b) supplying any additional information and documentary material that may be requested by any governmental authority under applicable law (provided, that no Foundation Member shall be required to
supply non-Company information or documentary material). 


  
 A-3

Risk Affiliates wishes to develop, construct, operate or otherwise implement an Expansion Project or New Project, it (“Proposing Party”) may by written notice propose that the relevant Enterprise Company implement, or participate
in, the Expansion Project or New Project (as applicable), in which case the Proposing Party must provide such detail in relation to the Expansion Project or New Project as is reasonably necessary to enable the other party (“Non-Proposing
Party”) to assess the merits of the project. 
  

	2.2	Sole Risk Project 

 If: 

 

	 	(a)	the proposed Expansion Project or New Project has not been approved by the Non-Proposing Party within 180 days of written notice of the proposal being given under clause 2.1; and 


 

	 	(b)	the proposed Expansion Project or New Project does not materially interfere with any Relevant Existing Project, 


the Proposing Party may, by giving written notice to the Non-Proposing Party, elect to conduct the proposed Expansion Project or New Project
(as applicable) as a sole risk project, in which case the Proposing Party: 
  

	 	(c)	in the case of a New Project, where it is feasible, shall conduct the project itself or through a nominated subsidiary (including, in either case without limitation, by the appointment of a manager); or


  

	 	(d)	in the case of an Expansion Project relating to an Enterprise Refinery, shall enter into an agreement with the relevant Enterprise Company to conduct the project under the direction of the Proposing Party (a
“Sole Risk Project Management Agreement”); or 

  

	 	(e)	in all other cases, may elect to: 

  

	 	(i)	conduct the project itself or through a nominated subsidiary (including, in either case without limitation, by the appointment of a manager); or

that same extent. 

  

	 	(g)	Where a Sole Risk Project is not the subject of a Sole Risk Project Management Agreement, and is functionally and operationally separate from the Enterprise Facilities, the Proposing Party may seek the approval of the
relevant Enterprise Company to apply a standard (other than the standard adopted by the relevant Enterprise Company) that is a reasonably acceptable industry standard, such approval not to be unreasonably withheld. 


 

	2.3	Conduct of Sole Risk Project operated by Proposing Party or nominated Sole Risk Affiliate 

  

	 	(a)	If the Sole Risk Project is conducted in accordance with clause 2.2(c) or clause 2.2(e)(i), the Proposing Party or its nominated Sole Risk Affiliate will develop, operate and manage the Sole Risk Project independently
of the Enterprise’s operations in accordance with this clause 2.3, except to the extent that the Proposing Party utilizes Enterprise Facilities as agreed or determined in accordance with clause 2.3(b). 


 

	 	(b)	A Proposing Party may utilize Enterprise Facilities in connection with a Sole Risk Project provided: 

  

	 	(i)	the Enterprise Facilities are not required or utilized, and are not reasonably expected to be required or utilized, for any Relevant Existing Project or reasonably expected projects, or have capacity in excess of that
which is required or utilized, or expected to be required or utilized, for Relevant Existing Projects or reasonably expected projects; and 

  

	 	(ii)	to the extent a Proposing Party may utilize Enterprise Facilities in accordance with clause 2.3(b)(i), the Proposing Party and the relevant Enterprise Company must negotiate in good faith with a view to entering into a
shared services agreement (“Shared Services Agreement”) with the Proposing Party pursuant to which the relevant Enterprise Company will allow utilization of the Enterprise Facilities on reasonable arms’ length terms. The amount
payable for use of the Enterprise Facilities should take into account the latent capacity of some or all of the Enterprise Facilities proposed to be used (including loss of option value) and any coordination costs. 


  
 B-3 









	 	(c)	The operation and management of the Sole Risk Project by the Proposing Party or its nominated subsidiary will be conducted such that: 


 

	 	(i)	the Proposing Party shall be the sole decision maker in respect of the Sole Risk Project, and will bear all risks associated with the Sole Risk Project; 


 

	 	(ii)	the Non-Proposing Party and the Strategic Council are not entitled to participate in any decision making regarding the Sole Risk Project except such decisions as may affect the Enterprise Facilities or that arise in
connection with the Sole Risk Project Management Agreement; 

  

	 	(iii)	during the period of construction and operation of the Sole Risk Project, the Proposing Party or its nominated subsidiary will use reasonable endeavors to minimize interference with, or disruption to, the Enterprise and
any Enterprise Project; 

  

	 	(iv)	the Non-Proposing Party is not entitled to receive any offtake arising from the Sole Risk Project in accordance with clause 2.7; and 


 

	 	(v)	the cost of the Sole Risk Project, including any payments under a Shared Services Agreement, will be borne by the Proposing Party in accordance with clause 2.8. 


 

	2.4	Conduct of Sole Risk Project operated by an Enterprise Company 

  

	 	(a)	If the Sole Risk Project is conducted in accordance with clause 2.2(d) or clause 2.2(e)(ii), the relevant Enterprise Company will operate and manage the Sole Risk Project in accordance with this clause 2.4 subject to
the applicable Sole Risk Project Management Agreement, which must include a requirement that during the period of construction and operation of the Sole Risk Project, the Enterprise Company will use reasonable endeavors to minimize interference
with, or disruption to, the Enterprise and any Enterprise Project; 

  

	 	(b)	The Enterprise Facilities may be utilized to conduct the Sole Risk Project to the extent that the Enterprise Facilities are not required or utilized, and are not reasonably expected to be required or utilized, for any
Relevant Existing Project or reasonably expected projects, or have capacity in excess of that which is required or utilized, or expected to be required or utilized, for Relevant Existing Projects or reasonably expected projects; 


 

	 	(c)	The Non-Proposing Party shall not be entitled to receive any offtake arising from the Sole Risk Project in accordance with clause 2.7; and 


 

	 	(d)	The cost of the Sole Risk Project will be borne by the Proposing Party in accordance with clause 2.8. 


  
 B-4 









	2.5	Obligation to proceed with Sole Risk Project within certain period 

 If a Sole Risk Project has
not commenced construction within 18 months of the time period specified in the proposed project terms, the Proposing Party cannot proceed without the approval of the Non-Proposing Party. 

 

	2.6	Rights to Enterprise tenement or concession rights 

  

	 	(a)	If the Sole Risk Project that is a New Project is conducted in accordance with clause 2.2(c) or clause 2.2(e)(i), the relevant Enterprise Company will use commercially reasonable endeavors to grant to the Proposing
Party or its subsidiary, or secure the grant to that party of, a right to use the Enterprise land, tenement or concession rights, to the extent reasonably necessary to undertake the Sole Risk Project. 


 

	 	(b)	The Enterprise Company will, at the request of the Proposing Party, use commercially reasonable endeavors to excise the portion of the tenement or concession on customary terms, including by creation of a sublease,
reasonably expected to contain the reserves and resources required for the Sole Risk Project. 

  

	 	(c)	If the existence of additional reserves or resources is established in the area that is the subject of a Sole Risk Project through further exploration (Additional Tonnes), the Proposing Party or Enterprise
Company, as the case may be, will notify the Foundation Members or, if different, their Ultimate Holding Companies, as soon as reasonably practicable. For the avoidance of doubt, any such Additional Tonnes will be assets of the Enterprise
Company. 

  

	2.7	Rights to production arising from a Sole Risk Project 

  

	 	(a)	If the Sole Risk Project is conducted in accordance with clause 2.2(d) or clause 2.2(e)(ii), the Proposing Party may exclusively purchase all offtake, including any bauxite or alumina, produced from the Sole Risk
Project at cost and the Non-Proposing Party shall not be entitled to receive any production from the Sole Risk Project and the Enterprise Company must enter into an offtake agreement with the Proposing Party to give effect to the offtake rights of
the Proposing Party. 

  

	 	(b)	If the Sole Risk Project is conducted in accordance with clause 2.2(c) or clause 2.2(e)(i), the Proposing Party will exclusively hold the legal title to all production resulting from the Sole Risk Project in accordance
with clause 2.7(a) and the Non-Proposing Party shall not be entitled to receive any production from the Sole Risk Project, and the Proposing Party will have the exclusive benefit of all property, plant and equipment built or acquired for the Sole
Risk Project. 


  
 B-5 









	 	(c)	If the production from an Enterprise Project (including an Expansion Project) reduces following completion of construction of that Enterprise Project then, to the extent that such reduction occurs as a result of actions
taken at the direction of: 

  

	 	(i)	the Proposing Party in connection with a Sole Risk Project, the offtake available to the Proposing Party will reduce; and 

  

	 	(ii)	an Enterprise Company in connection with an Enterprise Project, the offtake available to the Enterprise Company will reduce, 


and to the extent that reduction occurs as a result of an event that neither the Proposing Party and Enterprise contribute to or which the
Proposing Party and Enterprise each materially contribute to, then the offtake available to the Proposing Party and the Enterprise Company will reduce in proportion to the entitlement to offtake of each party. 

 

	 	(d)	The Proposing Party will have the exclusive benefit of all fixtures built or acquired for the Sole Risk Project with ownership of those fixtures residing with Enterprise Company. 


 

	 	(e)	The Enterprise will be entitled to use any unused capacity in infrastructure created by a Sole Risk Project, and the Proposing Party and the relevant Enterprise Company must negotiate in good faith with a view to
entering into a shared infrastructure agreement (“Infrastructure Sharing Agreement”) with the Proposing Party pursuant to which the Proposing Party will allow utilization of the infrastructure by the relevant Enterprise Company
on reasonable arms’ length terms. 

  

	2.8	Allocation of costs of Sole Risk Project 

  

	 	(a)	The Proposing Party must: 

  

	 	(i)	bear the entire cost and liability of developing, conducting, operating, closing and remediating the Sole Risk Project; 

  

	 	(ii)	pay the relevant Enterprise Company a fair market value amount (“Fair Market Value”) for any resources consumed; 


 

	 	(iii)	pay any costs in connection with any proposed excising of a portion of the land, tenements or concession rights following a request by the Proposing Party under clause 2.6, including the costs to the Enterprise Company
seeking and obtaining any government consent required and any duty or tax payable; 

  

	 	(iv)	pay the relevant Enterprise Company its costs, including reasonably allocated overhead and any other agreed payments, for use of the relevant Enterprise Facilities; 


 

	 	(v)	if the construction or operation of the Sole Risk Project results or is likely to result in a temporary decrease in the output or capacity of the Enterprise, which would result in an unavoidable loss of sales of bauxite
or alumina by the Enterprise Company, the Proposing Party must reimburse the Non-Proposing Party for such loss; and 

  

	 	(vi)	keep the relevant Enterprise Company and the Non-Proposing Party whole in respect of costs and liabilities arising from the Sole Risk Project, including any cost of bringing forward the closure date of an Enterprise
Mine or Enterprise Refinery or otherwise reducing the value of the Enterprise Facilities (whether or not directly utilized for the Sole Risk Project). 


  
 B-6 









	 	(b)	For the purposes of this Annex B, Fair Market Value will be agreed by the Proposing Party and the Enterprise Company or, failing agreement, will be determined by the average of three valuations determined by three
independent experts (“Valuers”): 

  

	 	(i)	based on the fact that the scheduled reserves and resources will be developed using the infrastructure assets available to the Enterprise; 


 

	 	(ii)	based on the quantity of scheduled reserves and resources, and other reasonably anticipated bauxite prospectivity, that the applicable feasibility study identifies as being scheduled for delivery to the Proposing Party
as part of the Sole Risk Project and the timing for delivery of those tonnes in accordance with the delivery schedule set out in the applicable feasibility study, taking into account any reduction in mine life arising from the consumption of those
reserves and resources; and 

  

	 	(iii)	each Valuer will value the transaction as between a willing but not anxious seller and a willing but not anxious buyer at arm’s length and have regard to all relevant matters including: 


 

	 	(A)	current and projected demand and supply conditions in the global bauxite market; 

  

	 	(B)	likely trends in bauxite quality specifications and pricing; 

  

	 	(C)	likely timing and scale of development and/or expansion of all relevant bauxite deposits; 

  

	 	(D)	quantum and nature of all relevant bauxite reserves and resources, including grade;

The items to be so allocated shall be determined in accordance with Sections 1.704-2(i)(4) and 1.704-2(j)(2) of the Regulations. 

(c) Qualified Income Offset. In the event any Member unexpectedly receives any adjustments, allocations, or distributions
described in Section 1.704-1(b)(2)(ii)(d)(4), Section 1.704-1(b)(2)(ii)(d)(5), or Section 1.704-1(b)(2)(ii)(d)(6) of the Regulations, items of Membership income and gain shall be specially allocated to each such Member in an

were not in the Agreement. 
 (e) Member Nonrecourse Deductions. Any Member Nonrecourse Deductions for any Fiscal Year shall be
specially allocated to the Member who bears the economic risk of loss with respect to the Member Nonrecourse Debt to which such Member Nonrecourse Deductions are attributable in accordance with Sections 1.704-2(i)(1) and 1.704-2(i)(2) of the
Regulations. 
 (f) Section 754 Adjustments. To the extent an adjustment to the adjusted tax basis of any Membership asset

a distribution to a Member in 

  
 15 








 
complete liquidation of its Interest, the amount of such adjustment to Capital Accounts shall be treated as an item of gain (if the adjustment increases the basis of the asset) or loss
(if the adjustment decreases such basis) and such gain or loss shall be specially allocated to the Members in accordance with their interests in AAC in the event Regulations Section 1.704-1(b)(2)(iv)(m)(2) applies,
or to the Member to whom such distribution was made in the event “’ Regulations Section 1.704-1(b)(2)(iv)(m)(4) applies. 
 2.5
Curative Allocations. The allocations set forth in Section 2.4 above (the “Regulatory Allocations”) are intended to comply with certain requirements of the Regulations. It is the intent of the
Members that, to the extent possible, all Regulatory Allocations shall be offset either with other Regulatory Allocations or with special allocations of other items of Membership income, gain, loss, or deduction pursuant to this
Section 2.5. Therefore, notwithstanding any other provision of this Article 2 (other than the Regulatory Allocations), the Members shall make such offsetting special allocations of Membership income, gain, loss, or deduction in
whatever manner they determine appropriate so that, after such offsetting allocations are made, each Member’s Capital Account balance is, to the extent possible, equal to the Capital Account balance such Member would have had if
the Regulatory Allocations were not part of the Agreement and all Membership items were allocated pursuant to Sections 2.2 and 2.3. In exercising their discretion under this Section 2.5, the Members shall take into account
future Regulatory Allocations under Sections 2.4(a) and 2.4(b) that, although not yet made, are likely to offset other Regulatory Allocations previously made under Section 2.4(e). 

2.6 Other Allocation Rules. 

(a) For purposes of determining the Profits, Losses, or any other items allocable to any period, Profits, Losses, and any such
other items shall be determined on a daily, monthly, or other basis, as determined by the Members using any permissible method under Code Section 706 and the Regulations thereunder. 

(b) The Members are aware of the income tax consequences of the allocations made by this Article 2 and hereby agree to be
bound by the provisions of this Section 2.6 in reporting their shares of Membership income and loss for income tax purposes. 

(c) Solely for purposes of determining a Member’s proportionate share of the “excess
nonrecourse liabilities” of AAC within the meaning of Section 1.752-3(a)(3) of the Regulations, the Members’ interests in Membership profits are in proportion to their Percentage Interests. 

(d) To the extent permitted by Section 1.704-2(h)(3) of the Regulations, the Members shall endeavor to treat
distributions of Net Cash Flow as having been made from the proceeds of a Nonrecourse Liability or a Member Nonrecourse Debt only to the extent that such distributions would cause or increase Adjusted Capital Account Deficit for any
Member. 

  
 16 








 2.7 Tax Allocations: Code Section 704(c). In accordance with Code Section 704(c) and the
Regulations thereunder, income, gain, loss, and deduction with respect to any property contributed to the capital of AAC shall, solely for tax purposes, be allocated among the Members so as to take account of any variation between the adjusted basis
of such property to AAC for federal income tax purposes and its initial Gross Asset Value (computed in accordance with Section 1.2(o)(i) hereof). 
 Any
elections or other decisions relating to such allocations shall be made by the Members in any manner that reasonably reflects the purpose and intention of this Agreement. Allocations pursuant to this Section 2.7 are solely for purposes of
federal, state, and local taxes and shall not affect, or in any way be taken into account in computing, any Member’s Capital Account or share of Profits, Losses, other items, or distributions pursuant to any provision of this Agreement. 

2.8 Additional Capital Contributions. Each Member may contribute from time to time such additional money or other Property as the Members may
