Remedies on Failure to Make Contributions. If a Shareholder (the “defaulting Shareholder”) fails to make a contribution required to be made by way of either Shareholder loans or subscriptions for additional Shares in accordance with Section or Section , the Corporation shall forthwith give written notice the defaulting Shareholder and to each other Shareholder specifying the amount of the required contribution that the defaulting Shareholder has failed to pay. If the defaulting Shareholder fails to make the required contribution within ten Business Days of such notice, then in addition to any other rights and remedies the Corporation may have to enforce the obligation to make the required contribution, the other Shareholder (the “non-defaulting Shareholder”) shall have the following rights

(a)

the non-defaulting Shareholder will be entitled (but not obligated) to loan funds to the Corporation on behalf of the defaulting Shareholder, which loan must be used by the defaulting shareholder to make the contribution (whether by loan or subscription for Shares) in respect of which it is in default. The amount so loaned shall be considered a loan by the non-defaulting Shareholder to the defaulting Shareholder (a “Contribution Loan”). Each Contribution Loan shall be repayable by the defaulting Shareholder upon demand and, until repaid, the amount outstanding from time to time shall bear interest at a rate per annum equal to 5% per annum above LIBOR, compounded monthly, payable at the same time as the payment of principal;

(b)

if the contribution in respect of which a default has occurred is required to be made by a loan, the non-defaulting Shareholder will be entitled (but not obligated) to loan funds to the Corporation on its own behalf on the same terms that such funds would have been loaned by the defaulting Shareholder. These loans will be repaid from funds available for distribution to the defaulting shareholder or which otherwise would have been available to repay loans made by the defaulting Shareholder in priority to the defaulting Shareholder’s right to receive such funds;

(c)

a non-defaulting Shareholder who has made a loan to the Corporation pursuant to Section 8.4(b) may elect to convert all or any such loans into additional shares. The number of Shares to be issued to the non-defaulting shareholder will be determined by multiplying the total then issued and outstanding shares by a fraction (a) the numerator of which is the amount of such loans which the non-defaulting Shreholder wishes to convert, and (b) the denominator of which is the aggregate equity and loan contributions made to the Corporation by both shareholders (and not then rapid), inclusive of all amounts contributed prior to the date hereof plus any amounts contributed pursuant to this Agreement, but excluding the Baja Funding Loan, and multiplying the number of shares so obtained by two. For the purpose of this determination, the total equity contribution nade by the Shareholders exclusive of the Baja Funding Loan shall be deemed to be $174,687,501 in the case of Invebaja, and $74,866,072 in the case of KBC. Such election will be communicated by the delivery of written notice in the manner contemplated by Section 18.11 to the Corporation of each member of the Shareholder Group which controls the defaulting Shareholder; and

(d)

if the contribution in respect of which a default has occurred is required to be made by a subscription for Shares, the non-defaulting Shareholder will be entitled (but not obligated) to purchase the Shares which were to have been purchased by the Defaulting Shareholder;

The rights and remedies provided in this Section are cumulative and not exclusive of any rights and remedies provided by law or otherwise.

8.5

Funding Structure. Unless otherwise agreed by the Parties, contributions will be made by each Shareholder in accordance with its respective shareholdings in the Corporation. The Parties will co-operate to make such changes to the structure (but not the monetary amounts) as may be reasonably required to accommodate relevant accounting, tax planning and operational considerations with respect to the Boleo Project.

Baja Funding Loan.

The Korean Consortium covenants that the Baja Funding Loan will be made in accordance with its terms. The Baja Funding Loan will, as and when made, be considered to be a Shareholder loan by Invebaja to the Corporation for the purpose of section 8.1, notwithstanding that it is made by and repayable to KBC in accordance with the Baja Funding Loan Agreement.

APPENDIX 4
DETERMINATION OF PURCHASE PRICE FOR SHARES

Each of the Baja Mining Shareholder Group and the Korean Consortium shall appoint a valuer to determine the fair market value of the Shares, being the value therefof if sold in a single transaction determined in an open and unrestricted market between prudent parties, acting at arm's length and under no compulsion to act, and having reasonable knowledge of all relevant facts concerning the Corporation (the “Valuation”). The Valuation shall be conducted in accordance with the valuation principles described below. Each of the Baja Mining Shareholder Group and the Korean Consortium shall appoint its valuer as soon as possible but no later than 21 days after the event giving rise to the requirement to determine a purchase price for Shares (the “Triggering Date”)

Each of the Baja Mining Shareholder Group and the Korean Consortium shall provide a copy of the Valuation prepared by its valuer to the other as soon as possible, but no later than 60 days after the Triggering Date.

The Baja Mining Shareholder Group and the Korean Consortium shall then endeavour to agree on a mutually acceptable purchase price for the Shares. If they cannot so agree within 30 days from the time both parties have received both Valuations, they shall appoint a third valuer, which valuer shall be qualified, independent and selected in compliance with the selection criteria described below and agreed to by both Parties. The third valuer shall prepare a Valuation and deliver it to each of the Parties as soon as possible, but no later than 30 days after the appointment of that valuer. The third Valuation shall then be compared to the first two Valuations. Whichever of the first two Valuations is closer to the third Valuation shall be accepted by and shall be binding upon all Parties, and the purchase price for the Shares determined in accordance with this Appendix shall be the purchase price indicated by that binding Valuation.

Notwithstanding any other provision of this Appendix, if either the Baja Mining Shareholder Group or the Korean Consortium shall fail to provide a copy of the Valuation prepared by its valuer within 60 days after the Triggering Date, the purchase price for the Shares determined in accordance with this Appendix shall be the purchase price indicated by the Valuation submitted by the other Shareholder Group.

Selection Criteria for Valuers

Each valuer shall be qualified to perform the Valuation, having regard to the valuer’s credentials and experience relevant to the subject matter of the Valuation.

No valuer shall be the independent auditor of the Corporation, any Shareholder or any affiliate of any Shareholder or any affiliate of such an auditor.

Each valuer shall be independent from the Parties appointing the valuer. In determining the independence of the valuer, a number of factors shall be considered, including:

(a)

the potential, if any, for bias on the part of the valuer as a result of the involvement of the valuer or any of its affiliates in an evaluation, appraisal or review of the financial status of either Shareholder or its affiliates or associates; and

(b)

the materiality to the valuer and its affiliates of the financial interest of the valuer and its affiliates in transactions during the 24 months preceding the date the valuer was first contacted in respect of the Valuation, in the completion of the subject transaction or in future business in respect of which an agreement, commitment or understanding exists involving either Shareholder or its affiliates and associates.

Lack of independence shall be deemed to exist in the following situations:

(a)

where the valuer is an insider, associate or affiliate of either Shareholder appointing the valuer;

(b)

where the valuer or any of its affiliates is an advisor to either Shareholder in respect of the transaction; or

(c)

where the compensation of the valuer or any of its affiliates depends in whole or in part on any arrangement or understanding which gives the valuer or any of its affiliates a financial incentive in respect of the conclusions reached in the Valuation or the outcome of the transaction.

A valuer does not lack independence solely by reason of the fact that a financial institution affiliated with such valuer provides in the ordinary course of business financial services to either Shareholder or its affiliates. However, the materiality of the financial services either to the Party or the financial institution is a relevant factor in determining the independence of the valuer. Where the financial services include being a lead lender or manager of the lending syndicate for the transaction in respect of which the Valuation is being obtained or where the financial services include being a lender of significant funds the possibility for repayment of which is materially enhanced by the transaction or where the financial circumstances of the Party or its affiliates is such that they could not readily replace the financial institution in question, the valuer shall be considered not to be independent.

A valuer does not lack independence solely by reason of the valuer being or having been a member (but not manager or co-manager) of a soliciting dealer group in respect of a bid made by a party to which all members of the Investment Dealers Association of Canada and The Toronto Stock Exchange are invited to join, where the valuer in its capacity as a soliciting dealer does not perform services beyond the customary soliciting dealer’s function and does not receive more than the per security or per security holder fees payable to other members of the soliciting dealer group.

The valuer must upon request disclose to the Parties any past, present or anticipated relationship between the valuer and either Shareholder appointing the valuer which may be relevant to a perceived lack of independence of the valuer, the compensation paid or payable to the valuer and any other factors relevant to a perceived lack of independence of the valuer. Such disclosure will not remedy a lack of qualification or independence of the valuer.

Valuation Principles

The Valuation must be performed in a diligent and professional manner.

The valuer must value the Shares.

The Valuation shall be as of a date that is not more than 120 days before the date of the transaction and shall contain appropriate adjustments for material intervening events. The valuer should take into account all material factors known or ascertainable as of the date the Valuation is delivered. The Parties must, on request by the valuer, promptly furnish the valuer with access to the management and advisors to the Corporation and to all information in their possession relevant to the Valuation, including all financial information they have furnished to their financiers or potential financiers of the proposed transaction. The valuer is expected to use that access to perform a comprehensive review and analysis of information upon which the Valuation is based. The valuer must form its own independent views of the reasonableness of this information, including any forecasts or projections or other measurements of the expected future performance of the enterprise, and of any of the assumptions upon which it is based and adjust the information accordingly.

In arriving at an opinion as to the fair market value for the Shares, regard should be had to the application of each valuation approach which is appropriate in the circumstances. Fair market valuation approaches could include:

(a)

capitalized earnings value;

(b)

capitalized and discounted cash flow value;

(c)

adjusted asset value;

(d)

comparable transaction value;

(e)

historical and prospective market prices relative to earnings and cash flow;

(f)

net book value;

(g)

going concern value;

(h)

liquidation value; and

(i)

break-up value.

Where relevant data is available, consideration should be given to market factors such as recent purchases or sales of comparable companies, assets, securities or liabilities, market price earnings ratios and market yields. If the transaction is considered in relation to purchases or sales or control positions of comparable companies or comparable assets or premiums paid in similar transactions, the transactions should be specifically identified and discussed.

No downward adjustment should be made to the Valuation of the Shares to reflect the liquidity of the Shares, the effect of the transaction or the fact that the Shares do not form part of a controlling interest.

The Valuation should contain a Section which considers and discusses any distinctive material value that might accrue to either Shareholder for whom the Valuation is prepared, based on information available. Possible benefits to be considered would include any distinctive material advantage that the Party would likely derive from the acquisition or disposition of the Shares such as, among other things, the earlier use of available tax losses, lower income taxes, reduced costs, increased revenues and higher utilization. The Valuation should disclose what amount, if any, of this value is included in the value arrived at and the reasons for the inclusion or exclusion.

The Valuation report must disclose the identity and credentials of the firm providing the Valuation, the identity and credentials of any individuals who were principally responsible for the report’s preparation, the date the valuer was first contacted in respect of the transaction, the date on which the valuer was retained, the financial terms of the retainer, the subject matter of the Valuation, the date of the Valuation, the scope and purpose of the Valuation, the meaning of the word “value” in the circumstances, a description of the type of information and sources upon which the valuer relied, a description of the type of any information the valuer requested but was denied, the valuation approaches considered, the key assumptions made, the relative importance attached to assumptions made and factors considered, any other experts relief upon and the valuation conclusion reached. The source of any fact which is material to the Valuation must be clearly stated, including sufficient details so that the significance of the fact can be reasonably assessed by a user of the report.

The disclosure in the report of the scope of review should include a description of any limitation on the scope of the review and the implications of the limitation on the valuer’s conclusion. Scope limitations should not be imposed by the Parties appointing the valuer or the valuer, but should be limited to those beyond the control of those persons which arise solely as a result of unusual circumstances.

10.

The valuation approach or approaches relied upon should be described and explained and the reasons for the reliance on a selected approach over another approach should be disclosed. Full disclosure will usually entail a comparison of valuation calculations and the conclusions arrived at through different methods. For example, if a certain valuation approach or approaches are considered to be appropriate, the calculations for the values determined should be disclosed and the rationale for accepting or rejecting them should be discussed fully.

11.

Consideration should be given to prior bona fide offers received within the 24 months preceding the date the valuer was retained pertaining to the subject matter of the Valuation and to prior valuations. Where the Valuation conflicts with any prior valuations disclosed, the differences should be explained where it is practicable to do so based on the information provided in the prior valuation.

12.

Disclosure must be made by the valuer in the Valuation of the nature of any undue influence any interested party had or attempted to have upon the valuer.

13.

Independent valuation or appraisal work that results in a draft or a preliminary prior valuation for which the prior valuer or appraiser was not paid a fee and internal appraisal or valuation analyses prepared by a Party in the ordinary course of business and not made available to or involving the participation of any of the senior officers or directors of the Party do not constitute prior valuations.

14.

A prior Valuation includes a fairness opinion, if valuation or appraisal work was conducted to support the fairness opinion, and includes the supporting valuation or appraisal work.

15.

Market analysts’ reports and similar financial analysis prepared by, for and at the expense of a person or company other than either Shareholder or its affiliates and associates which, to the knowledge of the person or company required to disclose prior valuations, is not based on material non-public information furnished by or on behalf of a Party does not constitute a prior valuation.

APPENDIX 5
ARBITRATION PROCEDURES

Any Dispute arising out of or in connection with this Agreement which is referred to arbitration pursuant to Section 17.1, including any questions regarding its existence, validity or termination, shall be referred to and finally resolved by arbitration under the London Court of International Arbitration Rules (the “Rules”) which are deemed to be incorporated by reference into this Agreement.

The number of arbitrators shall be three (one appointed by each Party and the Arbitrators so appointed shall agree on the appointment of an additional Arbitrator (the “Chairperson”)).

The seat, or legal place, of arbitration shall be Sydney, Australia.

The language to be used in the arbitral proceedings shall be English.

The governing law of the contract shall be the substantive law of England.

Each Party shall set out in reasonable detail its suggested resolution to the Dispute.

Any decision of the Arbitrators shall be made by a majority (failing a majority, by the Chairperson in accordance with the Rules). The Chairperson will vote in all circumstances.

4.2

Effect. Upon demand by the Lender as contemplated by section 4.1, the Lender may commence such legal action or proceedings as it may deem expedient, all without any additional notice, presentation, demand, protest, notice of dishonour, or any other action, notice of all of which the Borrower hereby expressly waives to the extent permitted by applicable law. The rights and remedies of the Lender hereunder are cumulative and are in addition to and not in substitution for any other rights or remedies provided by applicable law.

4.3

Right of Set-Off. Upon demand by the Lender as contemplated by section 4.1, the Lender is hereby authorized at any time and from time to time to set off and apply any and all deposits (general or special, time or demand, provisional or final, in whatever currency) at any time held and other obligations (in whatever currency) at any time owing by the Lender to or for the credit or the account of the Borrower against any and all of the Obligations.

Limitation on Exercise of Rights, Remedies and Set-Off. Notwithstanding the foregoing, the Lender shall not, prior to the Repayment Date, be entitled to exercise any rights or remedies under section 4.2 or any right of set-off under 4.3 unless, following demand being made under section 4.1, there are Available Funds available from which the Obligations may be repaid. In such event, such remedies may only be exercised to the extent that Available Funds are available, but have not been paid to the Lender in satisfaction or partial satisfaction of the Obligations.

5.4

Judgment Currency.

(1)

Exchange Rate. If, for the purposes of obtaining judgment in any court, it is necessary to convert a sum due hereunder to the Lender in one currency (in this section 5.4, the "Original Currency") into another currency (in this section 5.4, the "Judgment Currency"), the parties agree, to the fullest extent that they may effectively do so, that the rate of exchange used shall be that at which in accordance with normal banking procedures the Lender could purchase the Original Currency with the Judgment Currency on the Business Day preceding that on which final judgment is paid or satisfied.

(2)

Obligation. The obligations of the Borrower in respect of any sum due in the Original Currency from it to the Lender hereunder shall, notwithstanding any judgment in any Judgment Currency, be discharged only to the extent that, on the Business Day following receipt by the Lender of any sum adjudged to be so due in such Judgment Currency, the Lender may in accordance with normal banking procedures purchase the Original Currency with such Judgment Currency. If the amount of the Original Currency so purchased is less than the sum originally due to the Lender in the Original Currency, the Borrower agrees, as a separate obligation and notwithstanding any such judgment, to indemnify the Lender against such loss and, if the amount of the Original Currency so purchased exceeds the sum originally due to the Lender in the Original Currency, the Lender agrees to remit such excess to the Borrower.
