Without limiting clause 3.2 and subject to clause 3.3(b), each of Alcoa and Alumina must:

(Other conditions) Alcoa agrees that it must offer and agree or accept, any undertakings, commitments or conditions imposed, required or requested by the Regulatory Authority in relation to the relevant Regulatory Approval on terms that Alcoa considers to be acceptable (acting reasonably).

3.5

Alumina Shareholder Approval

If the Condition Precedent in clause 3.1(d) is not satisfied only because of a failure to obtain the majority required under 411(4)(a)(ii)(A) of the Corporations Act, then either Alumina or Alcoa may by written notice to the other party within 3 Business Days after the date of the conclusion of the Scheme Meeting require the approval of the Court to be sought, pursuant to the Court’s discretion under that section, provided that the party has in good faith formed the view that the prospect of the Court exercising its discretion in that way is reasonable. If approval is given, the Condition Precedent in clause 3.1(d) is deemed to be satisfied.

3.6

Waiver of Conditions Precedent

(a)

A Condition Precedent may only be waived in writing by the party or parties entitled to the benefit of that Condition Precedent as noted in clause 3.1 and will be effective only to the extent specifically set out in that waiver.

(b)

A party entitled to waive the breach or non-fulfilment of a Condition Precedent under this clause 3.6 may do so in its absolute discretion.

(c)

If either Alumina or Alcoa waives the breach or non-fulfilment of a Condition Precedent in accordance with this clause 3.6, then:

(i)

subject to clause 3.6(c)(ii), that waiver precludes that party from suing the other party for any breach of this document arising as a result of the breach or non-fulfilment of that Condition Precedent or arising from the same event which gave rise to the breach or non-fulfilment of that Condition Precedent; but

(ii)

if the waiver of the Condition Precedent is itself conditional and the other party:

(A)

accepts the condition, the terms of that condition apply notwithstanding any inconsistency with clause 3.6(c)(i); or

(B)

does not accept the condition, the Condition Precedent has not been waived.

(d)

A waiver of a breach or non-fulfilment in respect of a Condition Precedent does not constitute a waiver of a breach or non-fulfilment of:

(i)

any other Condition Precedent arising from the same event; or

(ii)

that Condition Precedent resulting from any other event.

3.7

Notices in relation to Conditions Precedent

Each party must:

(a)

(notice of satisfaction) promptly notify the other party of satisfaction of a Condition Precedent;

(b)

(keep informed) keep each other party informed of any material development of which it becomes aware that may lead to the breach or non-fulfilment of a Condition Precedent;

(c)

(notice of failure) immediately give written notice to each other party of a breach or non-fulfilment of a Condition Precedent, or of any event which will prevent a Condition Precedent being satisfied; and

(d)

(notice of waiver) upon receipt of a notice given under clause 3.7(c), give written notice to each other party as soon as possible as to whether or not it waives the breach or non-fulfilment of any Condition Precedent resulting from the occurrence of that event, specifying the Condition Precedent in question.

Failure to provide a notice required under this clause 3.7 will not give rise to the failure of a Condition Precedent or any right to terminate this document.

3.8

Consultation on failure of Condition Precedent

If:

(a)

there is a breach or non-fulfilment of a Condition Precedent which is not waived in accordance with this document by the time or date specified in this document for the satisfaction of the Condition Precedent; or

(b)

there is an act, failure to act or occurrence which will prevent a Condition Precedent being satisfied by the time or date specified in this document for the satisfaction of the Condition Precedent (and the breach or non-fulfilment which would otherwise occur has not already been waived in accordance with this document),

the parties must consult in good faith with a view to determining:

(c)

whether the Scheme may proceed by way of alternative means or methods so as to achieve substantially similar commercial outcomes;

(d)

to extend the relevant time for satisfaction of the Condition Precedent or to adjourn or change the date of an application to the Court; or

(e)

to extend the End Date.

3.9

Failure to agree

If the parties are unable to reach agreement under clause 3.8 within 5 Business Days of reasonable consultation (or any shorter period ending at 5.00pm on the day before the Second Court Date):

(a)

subject to clause 3.9(b), either Alcoa or Alumina may terminate this document (in accordance with clause 14.1(g)(i)); or

(b)

if a Condition Precedent may be waived and exists for the benefit of one party only, that party only may waive that Condition Precedent or terminate this document (in accordance with clause 14.1(g)(ii)),

in each case before 8.00am on the Second Court Date.

A party will not be entitled to terminate this document pursuant to this clause 3.9 if the relevant Condition Precedent has not been satisfied or agreement cannot be reached as a result of a breach of this document by that party or a deliberate act or omission of that party. For the avoidance of doubt, nothing in this clause 3.9 affects the obligation of Alumina to pay the Break Fee, or the obligation of Alcoa to pay the Reverse Break Fee, if it is required to do so under clause 11 or clause 12 (as applicable).

4	Outline of Scheme

4.1

Scheme

Alumina must propose a scheme of arrangement under which:

(a)

all of the Alumina Shares held by Scheme Participants at the Scheme Record Date will be transferred to Alcoa Bidder; and

(b)

each Scheme Participant will be entitled to receive the Scheme Consideration.

4.2

Scheme Consideration

Subject to and in accordance with this document and the Scheme, each Scheme Participant is entitled to receive the Scheme Consideration in respect of each Alumina Share held by that Scheme Participant.

4.3

CITIC Shareholders

Where, on the Implementation Date:

(a)

Alcoa Shares (including the New Alcoa CDIs) that the CITIC Shareholders, collectively, would receive as Scheme Consideration without giving effect to clause 5.4 of the Scheme;

(b)

less any New Alcoa Shares that a CITIC Shareholder would have otherwise been entitled to as Scheme Consideration (in the form of New Alcoa CDIs) that will instead be sold via the sale facility described in clause 4.6, as contemplated by clause 20(d) to fund any applicable Withholding Amount,

represent beneficial ownership in aggregate of more than 4.5% of the total number of Alcoa Shares (including the New Alcoa Shares) that would be issued and outstanding on the Implementation Date (CITIC Threshold), the Scheme Consideration to which the CITIC Shareholders, collectively, are entitled to in excess of the CITIC Threshold must instead be issued as New Alcoa Preferred Shares to Bestbuy Overseas Co. Ltd.

4.4

Provision of Scheme Consideration

Subject to this document and the Scheme, each of Alcoa and Alcoa Bidder undertakes to Alumina (in its own right and separately as trustee or nominee of each Scheme Participant) that, in consideration of the transfer to Alcoa Bidder of each Alumina Share held by a Scheme Participant, on the Implementation Date, Alcoa Bidder will:

(a)

accept that transfer;

(b)

provide (or procure as set out in clause 4.4(c) the provision of) the Scheme Consideration to each Scheme Participant in accordance with this document and the Scheme; and

cause Alcoa to, and Alcoa will at the direction of and on behalf of Alcoa Bidder (in satisfaction of Alcoa Bidder’s obligation to provide such Scheme Consideration to the Scheme Participants under clause 4.4(b)), provide the Scheme Consideration to each Scheme Participant in accordance with this document and the Scheme. If Alcoa Bidder fails to provide direction to Alcoa as contemplated by this clause 4.4(c) (or to have otherwise procured the provision of the Scheme Consideration) within one Business Day following the Effective Date, Alcoa Bidder will be deemed to have provided such direction to Alcoa and Alcoa agrees that it will take the actions required by this clause 4.4(c).

4.5

Fractional entitlements

(a)

If the number of Alumina Shares held by a Scheme Participant at the Scheme Record Date is such that the aggregate entitlement of the Scheme Participant to New Alcoa CDIs, New Alcoa Preferred Shares or New Alcoa Shares (as applicable) includes a fractional entitlement to a New Alcoa CDI, a New Alcoa Preferred Share or a New Alcoa Share (as applicable), the fractional entitlement will be rounded as follows:

(i)

if the fractional entitlement is less than 0.5, it will be rounded down to zero; and

(ii)

if the fractional entitlement is equal to or more than 0.5, it will be rounded up to one.

(b)

If Alcoa or Alumina is of the opinion that two or more Scheme Participants (each of whom holds a number of Alumina Shares which results in rounding in accordance with clause 4.5(a)(ii)) have, before the Scheme Record Date, been party to a shareholding splitting or division in an attempt to obtain an advantage by reference to such rounding, Alumina must provide the relevant details of the relevant Scheme Participant to Alcoa, and if requested by Alcoa, Alumina must give notice to those Scheme Participants:

(i)

setting out their names and registered addresses as shown in the Register;

(ii)

stating that opinion; and

(iii)

attributing to one of them specifically identified in the notice the Alumina Shares held by all of them,

and, after such notice has been given, the Scheme Participant specifically identified in the notice as the deemed holder of the specified Alumina Shares will, for the purpose of the provisions of the Scheme, be taken to hold all of those Alumina Shares and each of the other Scheme Participants whose names and registered addresses are set out in the notice will, for the purposes of the provisions of the Scheme, be taken to hold no Alumina Shares.

4.6

Ineligible Foreign Shareholders

(a)

Where an Ineligible Foreign Shareholder would otherwise be entitled to receive New Alcoa CDIs as Scheme Consideration pursuant to clause4.4, each of Alcoa and Alcoa Bidder must not and have no

obligation to issue or procure the issuance of any of the relevant New Alcoa CDIs to the Ineligible Foreign Shareholder, and instead:

(i)

Alcoa must issue or procure the issue of any relevant New Alcoa Shares to a nominee appointed by Alcoa (Sale Nominee) to which an Ineligible Foreign Shareholder would otherwise be entitled to receive in the form of New Alcoa CDIs (which, for the avoidance of doubt, where clause 20(d) applies, is only the New Alcoa Shares to be sold to fund the Withholding Amount and brokerage, stamp duty and other selling costs, taxes and charges in respect of the sale of those New Alcoa Shares) (Relevant Alcoa Shares);

(ii)

Alcoa must procure that the Sale Nominee:

(A)

as soon as reasonably practicable after the Implementation Date (and in any event within 15 days after the Relevant Alcoa Shares are capable of being traded on NYSE), sells or procures the sale of all of the New Alcoa Shares issued to the Sale Nominee pursuant to clause 4.6(a)(i), in the ordinary course of trading on NYSE at such price as the Sale Nominee reasonably determines in good faith; and

(B)

as soon as reasonably practicable after settlement (and in any event within 10 Pittsburgh Business Days), remits to Alcoa Bidder the proceeds of such sale (net of any applicable brokerage, stamp duty and other selling costs, taxes and charges) (Proceeds); and

(iii)

promptly after receiving the Proceeds in accordance with clause 4.6(a)(ii)(B), but subject to clause subject to clause 20(d), Alcoa Bidder must pay or procure Computershare to pay to each Ineligible Foreign Shareholder an amount equal to the proportion of the Proceeds of sale received by Alcoa Bidder under clause 4.6(a)(ii)(B) to which that Ineligible Foreign Shareholder is entitled (rounded down to the nearest cent) in full satisfaction of the Ineligible Foreign Shareholder entitlement to the relevant New Alcoa CDIs, being, in respect of an Ineligible Foreign Shareholder who is:

(A)

a Withholding Amount Shareholder, the amount described in clause 6.4(c)(i) of the Scheme;

(B)

not a Withholding Amount Shareholder, the amount described in clause 6.4(c)(ii) of the Scheme.

(b)

Alcoa must appoint the Sale Nominee on terms reasonably acceptable to Alumina at least 5 Pittsburgh Business Days before the date of the Scheme Meeting.

(c)

None of Alcoa, Alcoa Bidder, Alumina or the Sale Nominee gives any assurance as to the price that will be achieved for the sale of New Alcoa Shares in accordance with this clause 4.6 and the sale of New Alcoa Shares will be at the risk of the Ineligible Foreign Shareholder.

the Independent Expert Report concludes, or is amended or updated in writing so as to conclude, that the Scheme is not in the best interests of Alumina Shareholders; or

(iii)

the Court or ASIC requires or reasonably requests that the relevant Alumina Board Member abstains from making a recommendation.

(c)

Without limiting clause 10, if any Alumina Board Member proposes to adversely change, withdraw, qualify or modify their recommendation from the form in the public announcement contained in Annexure A or otherwise make a public statement indicating that they no longer support the Scheme or support or endorse an Alumina Competing Transaction, in each case in accordance with this clause 7.1, Alumina must notify Alcoa in writing as soon as practicable.

(d)

For the purposes of this clause 7.1, qualifications and explanations contained in the Scheme Booklet in relation to a recommendation to vote in favour of the Scheme, including to the effect that the recommendation is made subject to:

(i)

there being no Alumina Superior Proposal;

(ii)

the Independent Expert concluding and continuing to conclude that the Scheme is in the best interests of Alumina Shareholders; or

(iii)

the Court or ASIC requiring or requesting that the relevant Alumina Board Member abstains from making a recommendation,

will not, in and of itself, be regarded as a failure to make or a withdrawal of a recommendation in favour of the Scheme by an Alumina Board Member.

(e)

Despite anything to the contrary in this clause 7.1, a statement made by Alumina, the Alumina Board or any Alumina Board Member, to the effect that no action should be taken by Alumina Shareholders pending the assessment of an Alumina Competing Transaction by Alumina or the completion of the procedure in clause 10.8 will not, in and of itself, contravene this clause 7.1.

7.2

Alcoa Board recommendation

(a)

Alcoa represents and warrants to Alumina that, as at the date of this document, each Alcoa Board Member has confirmed that:

(i)

his or her intention is to recommend that Alcoa Stockholders vote in favour of the Alcoa Stockholder Resolution at the Alcoa Stockholder Meeting; and

(ii)

he or she intends to vote, or cause to be voted, all Alcoa Shares which he or she holds in favour of the Alcoa Stockholder Resolution at the Alcoa Stockholder Meeting,

in each case, subject to there being no Alcoa Superior Proposal.

(b)

Alcoa must use its best endeavours to procure that no Alcoa Board Member changes, withdraws, qualifies or modifies their recommendation that Alcoa Stockholders vote in favour of the Alcoa Stockholder Resolution, unless Alcoa has received an Alcoa Superior Proposal and the Alcoa Board has determined in good faith and acting reasonably having received advice from its external counsel specialising in corporate law that failure to do so would constitute a breach of their fiduciary or statutory obligations to Alcoa Stockholders.

(c)

Without limiting clause 10, if an Alcoa Board Member proposes to change, withdraw, qualify or modify their recommendation, Alcoa must notify Alumina in writing as soon as practicable.

(c)

Alcoa indemnifies the Alumina Indemnified Parties against all Losses incurred as a result of a breach of clauses 8.7(a)(i) to 8.7(a)(iv), 8.7(b), 8.8(a) or 8.8(b).

9.6

Funding of equity calls

(a)

Notwithstanding any restrictions in or imposed by the Charter of the Strategic Council, Alcoa and Alumina agree that, from the date of this document up to and including the Lending Cessation Date,

any funding required to meet the needs of AWAC or the AWAC Entities will be met first, out of the cashflow of AWAC and the AWAC Entities, and secondly:

(i)

by way of equity call made in accordance with Section 8(a) of the Charter of the Strategic Council, subject to clause 9.6(a)(ii) below; and

(ii)

if Alumina is unable to contribute its share of the relevant equity call without its total “Loans” (as defined in the Alumina Facility Agreement) exceeding the Alumina Headroom Limit, and Alumina elects to notify Alcoa and the applicable AWAC Entity that it requires funding under this clause 9.6(a)(ii) within 14 days of the equity call, by the following mechanism:

(A)

the applicable AWAC Entity confirming the equity call in respect of the relevant funding requirement (being the Aggregate Equity Amount);

(B)

Alcoa procuring that the applicable AWAC Entity makes the equity call to Alumina only payable on the Funding Deadline, with the amount payable by Alumina to satisfy the call being equal to 40% (or such lesser percentage as may represent Alumina’s interest in the AWAC Entity at that time) of the Aggregate Equity Amount plus Accrued Interest;

(C)

Alcoa providing, or procuring that one of its Subsidiaries (other than an AWAC Entity) provides a shareholder loan (Alcoa Shareholder Loan) to the applicable AWAC Entity for a principal amount equal to 40% (or such lesser percentage as may represent Alumina’s interest in AWAC at that time) of the Aggregate Equity Amount, plus capitalised interest, and on terms that are in accordance with and governed by the applicable Alcoa Shareholder Loan Agreement, and on the basis that there will be no dilution of Alumina’s interest in AWAC, by virtue of the Alcoa Shareholder Loan, other than in the circumstances contemplated by clause 9.6(d); and

(D)

immediately following payment of some or all of the equity call to which it relates by Alumina, Alcoa procuring that the applicable AWAC Entity repays the Alcoa Shareholder Loan (in full or, if the amount of the Alumina payment of the equity call is less than the total amount outstanding under the Alcoa Shareholder Loan, in part to the extent of the Alumina payment only).

For the avoidance of doubt, if Alumina does not elect to notify Alcoa and the applicable AWAC Entity that it requires funding under clause 9.6(a)(ii) within the 14 day period referred to in the first paragraph of clause 9.6(a)(ii), Alumina will be obliged to contribute its share of that equity call in accordance with Section 8(a) of the Charter of the Strategic Council.

If Alumina elects to notify Alcoa and the applicable AWAC Entity that it requires funding under this clause 9.6(a)(ii) within 14 days of the equity call, then Alumina and Alcoa shall negotiate in good faith for a period ending on the last day of the 30 day notice period for that equity call to agree the form of the Alcoa Shareholder Loan Agreement. If, at the end of such negotiation period, Alcoa and Alumina have not agreed the form of the Alcoa Shareholder Loan Agreement, then Alcoa may execute a form of Alcoa Shareholder Loan Agreement, on terms consistent with the Shareholder Loan Term Sheet, with the relevant AWAC Entity.

(b)

Provided that Alumina has complied with clause 9.6(a), Alumina will continue to receive distributions reflecting a 40% (or such lesser percentage as may represent Alumina’s interest in AWAC at that time) interest in AWAC and the AWAC Entities, including prior to the Funding Deadline.

(c)

If an Alcoa Shareholder Loan has been advanced in accordance with clause 9.6(a)(ii)(C) and has not been repaid in full in accordance with this clause 9.6 at the relevant time of distribution:

(i)

Alumina agrees that any distributions that it is entitled to from an AWAC Entity will be used to satisfy equity calls made to it by an AWAC Entity, and hereby directs that such distributions are applied accordingly; and

(ii)

Alumina must not declare or pay any distributions to Alumina Shareholders or undertake any other return of capital until such time as the relevant Alcoa Shareholder Loan has been repaid in full or converted to equity in accordance with clause 9.6(d) below.

If Alumina breaches this clause 9.6(c)(ii), any outstanding equity call at the time of the breach will immediately accelerate and require payment in full of Alumina’s share of the Aggregate Equity Amount within 5 Business Days.

(d)

If Alumina does not make one or more equity contributions by the Funding Deadline as required under clause 9.6(a), Alcoa may, at its election, contribute Alumina’s share by effectively converting the corresponding Alcoa Shareholder Loan(s) into an equity contribution on behalf of Alumina in the manner set out in subsection (i) of Section 8(a) of the Charter of the Strategic Council, and Alumina agrees that, in this scenario, its interest in AWAC and each of the AWAC Entities will be diluted by reference to the amount of the Alcoa Shareholder Loan so converted into an equity contribution, in accordance with the formula set out in Exhibit A of the Charter of the Strategic Council.

(e)

For the purposes of clause 9.6(a), Alcoa must procure that any Alcoa Shareholder Loan will be provided without being limited by reference to either:

(i)

the Target Enterprise Debt Level (as defined in the Charter of the Strategic Council); or

(ii)

the Debt (as defined in the Charter of the Strategic Council) limit set out in Section 9(b) of the Charter of the Strategic Council,

and the parties agree, on their own part and on behalf of each other relevant Alumina Group Member or Alcoa Group Member (as applicable), to waive compliance with those relevant limitations in the Charter of the Strategic Council to the extent necessary to give full effect to this clause 9.6.

(f)

Alcoa acknowledges and agrees that it will not, and will procure that each relevant Alcoa Group Member does not:

(i)

amend or vary the terms of any Alcoa Shareholder Loan Agreement; or

(ii)

waive any rights under, or assign, novate or replace, any Alcoa Shareholder Loan Agreement,

or otherwise consent to any of the foregoing, without Alumina’s prior written consent (such consent not to be unreasonably withheld or delayed).

(g)

Subject to clause 9.6(c), if this document is terminated in accordance with clause 14.1, then Alcoa must ensure that:

(i)

it does not effect or procure repayment of any Alcoa Shareholder Loan; and

(ii)

there is no breach, event of default or other event or circumstance which obliges or requires repayment of any such Alcoa Shareholder Loan,

in each case during the period ending on the Funding Deadline.

(h)

For the avoidance of doubt, the parties agree that:

(i)

any repayment of an Alcoa Shareholder Loan in accordance with this clause 9.6 will not impact or affect in any way the continuation of other existing AWAC debt funding that has been put in place to satisfy the requirements of Section 9 of the Charter of the Strategic Council, or the parties’ ongoing obligations under Section 9 of the Charter of the Strategic Council;

(ii)

there will be no dilution of Alumina’s interest in AWAC during the period up to the Funding Deadline; and

(iii)

to the extent of any inconsistency between the operation of this clause 9.6 and any other AWAC Agreement, this clause 9.6 will prevail.

(i)

This clause 9.6 survives the termination of this document.

9.7

Access to information

(a)

During the Exclusivity Period, Alumina and Alcoa must procure that their respective chief financial officers meet not less than fortnightly to provide material updates in connection with the Alumina Group and Alcoa Group (as applicable), including but not limited to:

(ii)

(iii)

any information reasonably requested by Alcoa, any Alcoa Group Member or any of their Representatives or Alumina, any Alumina Group Member or any of their Representatives, for the purposes of:

(A)

keeping Alcoa or Alumina (as applicable) informed of material developments relating to the Alumina Group or Alcoa Group (as applicable) and the businesses of the Alumina Group or Alcoa Group (as applicable); or

(B)

obtaining an understanding, or furthering an understanding, of the Alumina Group, the businesses of the Alumina Group or the financial position of the Alumina Group (including its cash flow, debt and working capital position) or the Alcoa Group, the businesses of the Alcoa Group or the financial position of the Alcoa Group (including its cash flow, debt and working capital position); or

(iv)

for any other purpose agreed between Alumina and Alcoa.

(b)

Nothing in clause 9.7(a) requires Alcoa or any other Alcoa Group Member to provide any additional information in relation to AWAC, any AWAC Agreement or any AWAC Entity that it would not otherwise be required to provide to the Alumina Group in accordance with (i) the AWAC Agreements or (ii) another provision of this document.

9.8

9.9

Payment of dividends

For the purposes of this document, a reference to declaration of a dividend will include determination that a dividend is payable.

(b)

For the avoidance of doubt, the Scheme Consideration will not be adjusted by any Alcoa Capped Dividend.

(ii)

not to contact any Alumina Shareholders in connection with the application of Subdivision 14-D or other withholding obligation to the Scheme without Alumina’s prior written consent.

(d)

At all times subject to clause 20(e), if Alcoa determines, acting reasonably, that it is necessary, in order to fund a Withholding Amount payable in respect of any Withholding Amount Shareholder:

(i)

that Withholding Amount Shareholder will be treated, for the purposes of the Scheme, as an Ineligible Foreign Shareholder in relation to an amount of New Alcoa Shares that the Withholding Amount Shareholder would otherwise be entitled to as Scheme Consideration (in the form of New Alcoa CDIs) under clause 4.4, but only to the extent necessary to fund the Withholding Amount paid or payable by Alcoa Bidder under Subdivision 14-D in respect of that Withholding Amount Shareholder and for the avoidance of doubt to fund any brokerage, stamp duty and other selling costs, taxes and charges in respect of a sale of Relevant Alcoa Shares (the number of New Alcoa Shares required to fund these amounts to be determined by Alcoa and Alcoa Bidder acting reasonably);

reflect the withholding under this clause and the net aggregate consideration payable to that Withholding Amount Shareholder will be taken to be in full and final discharge of the Scheme Consideration owing to that Withholding Amount Shareholder.

(e)

The parties agree to:

(i)

consult in good faith as to the application of Subdivision 14-D in connection with the Scheme; and

(ii)

subject to clause 20(c)(ii), use reasonable endeavours to take all actions that are necessary or desirable in relation to Subdivision 14-D, which may include, without limitation, promptly communicating with any Withholding Amount Shareholder to obtain a Valid Variation Notice or Entity Declaration contemplated by Subdivision 14-D Law so as to reduce or eliminate the Withholding Amount payable to the Commissioner of Taxation in respect of any Withholding Amount Shareholder.

(c) Immediately upon a conversion pursuant to Section III(a) or Section III(b), the rights of the Holders with respect to the shares of the Non-Voting Preferred Stock so converted shall cease and the Persons entitled to receive the shares of Common Stock upon the conversion of such shares of Non-Voting Preferred Stock shall be treated for all purposes as having become the record and beneficial owners of such shares of Common Stock. In the event that a Holder shall not by written notice designate the name in which shares of Common Stock and/or cash, securities or other property (including payments of cash in lieu of fractional shares) to be issued or paid upon conversion of the shares of Non-Voting Preferred Stock should be registered or paid or the manner in which such shares should be delivered, the Corporation shall be entitled to register and deliver such shares, and make such payment, in the name of the Holder and in the manner shown on the records of the Corporation.

(e) No fractional shares of Common Stock shall be issued upon any conversion of shares of Non-Voting Preferred Stock. If more than one share of Non-Voting Preferred Stock shall be surrendered for conversion at any one time by the same Holder, the number of full shares of Common Stock issuable upon conversion thereof shall be computed on the basis of the aggregate number of shares of Non-Voting Preferred Stock so surrendered. Instead of any fractional shares of Common Stock which would otherwise be issuable upon conversion of any shares of Non-Voting Preferred Stock, such fractional share will be rounded as follows: (i) if the fractional share is less than 0.5 shares, it will be rounded down to zero; and (ii) if the fractional entitlement is equal to or more than 0.5 shares, it will be rounded up to one.

(f) All shares of Common Stock which may be issued upon conversion of the shares of Non-Voting Preferred Stock will, upon issuance by the Corporation, be duly authorized, validly issued, fully paid and non-assessable, and not issued in violation of any preemptive right or Law.

(g) Effective immediately prior to the applicable Conversion Date, dividends or distributions shall no longer be declared on the shares of Non-Voting Preferred Stock subject to conversion and such shares of Non-Voting Preferred Stock shall cease to be outstanding, in each case, subject to the rights of Holders to receive any declared and unpaid dividends or distributions on such shares and any other payments to which they are otherwise entitled pursuant to Section IV.

Notwithstanding any provision in this Section IV(a) to the contrary, no Holder of a share of Non-Voting Preferred Stock shall be entitled to receive any dividend or distribution made with respect to the Common Stock where the Record Date for determination of holders of Common Stock entitled to receive such dividend or distribution occurs prior to the date of issuance of such share of Non-Voting Preferred Stock.
