(together the parties).

The Parent Company enters into this Agreement solely in its capacity of a guarantor under clause 25 of this Agreement and by execution of this Agreement shall not have or be deemed to have any obligations or liabilities under this Agreement other than expressly stipulated in clause 25 of this Agreement.

Words and expressions used in this Agreement shall be interpreted in accordance with Schedule 10.

WHEREAS:

(A) The Purchaser has agreed to purchase all the issued share capital of AES Kazakhstan Holdings BV, AES Ekibastuz Holdings BV and Emerging Energy Investments & Holdings BV, which together hold (indirectly or directly) certain interests of The AES Corporation (AES) in the Target Companies (as defined below and as listed in Schedule 1 of this Agreement) including AES Ekibastuz LLP, the operator of the AES Ekibastuz power plant in Kazakhstan and Maikuben West LLP, the owner of the Maikuben West coal mine in Kazakhstan, from the Seller, which is an indirectly owned subsidiary of AES, for the consideration and upon the terms and subject to the conditions set out in this Agreement.

(B) The parties have agreed a total consideration in respect of the Shares being sold of up to $1,525,000,000. Such total consideration is subject to (i) certain post-closing financial adjustments in respect of cash and external debt and certain other line items as is described further below in Schedule 9; (ii) such performance discounts as may be applicable in respect of the Earnout Consideration of up to $320,000,000, as further set out in Schedule 7 and (iii) otherwise as provided herein or in the Management Agreement.

IT IS AGREED:

1. SALE AND PURCHASE

1.1 The Seller shall sell, with full title guarantee, and the Purchaser shall purchase, the Shares on the terms set out in this Agreement.

1.2 The Shares shall be sold free of all Encumbrances with all rights attaching to them at Closing including the right to receive all distributions and dividends declared, paid or made in respect of the Shares after Closing.

1.3 The Seller covenants with the Purchaser that it has the right to sell and transfer to the Purchaser the full legal and beneficial interest in the Shares on the terms set out in this Agreement.

2. PRICE

2.1 The initial price for the Shares (the Initial Price) shall be the amount which results from taking $1,150,000,000 (one billion one hundred fifty million US dollars) and:

(a) subtracting the amount of the External Debt of the Group Companies as shown in the 30 September 2007 Accounts as set out in Part C of Exhibit 2;

(b) adding the amount of Cash of the Group Companies as shown in the 30 September 2007 Accounts as set out in Part B of Exhibit 2;

(c) subtracting the amount of the difference between the External Debt as at the Closing Date as agreed between the Seller and the Purchaser (the Estimated External Debt) and the External Debt as shown in the 30 September 2007 Accounts if the former is more than the latter (or adding the amount of such difference if the former is less than the latter); and

(d) adding the amount of the difference between the Cash as at the Closing Date as agreed between the Seller and the Purchaser (the Estimated Cash) and the Cash as shown in the 30 September 2007 Accounts if the former is more than the latter (or subtracting the amount of such difference if the former is less than the latter).

The Seller shall provide the Purchaser with its calculation in good faith of the amounts of the Estimated External Debt, the Estimated Cash and the amounts to be paid under Schedule 8 (together with supporting documentation, such documentation to include the most recent (prior to Closing) monthly management accounts of the relevant Group Companies) no later than 7 Business Days prior to Closing. The Calculation of the Initial Price shall be in the form set out in Exhibit 4. The Seller and the Purchaser shall seek to agree the Calculation of the Initial Price in good faith prior to Closing. However, if no such agreement has been reached by no later than 3 Business Days prior to the Closing Date, the amounts shown in the most recent (prior to Closing) monthly management accounts of the relevant Group Companies shall be used to determine the Estimated External Debt and the Estimated Cash for the purposes of clause 2.1(c) and (d) and the amounts to be paid under Schedule 8.

2.2 At Closing, the Purchaser shall pay to the Seller the Initial Price as calculated in accordance with Clause 2.1 above, subject to Clause 2.3 below.

2.3 At Closing the Parties shall make the payments contemplated by paragraph 2 of Schedule 8 in relation to net Inter-Company Debt. Any payment made by the Purchaser to the Seller pursuant to paragraph 2 of Schedule 8 will reduce the Initial Price payable at Closing on a dollar-for-dollar basis (and any payment made by the Seller to the Purchaser pursuant to paragraph 2 of Schedule 8 will increase the Initial Price payable at Closing on a dollar-for-dollar basis).

2.4 The Final Price shall be calculated after Closing on the basis set out in Schedule 9. Any payments required to be made under the Financial Adjustments shall be treated as adjusting the Initial Price, thus resulting after such adjustment in the Final Price.

2.5 Notwithstanding anything to the contrary in this Agreement, no payments shall be made under the Financial Adjustments in the event that such payments would not exceed in aggregate the sum of $2,000,000 (provided that, if such payments would exceed $2,000,000, the whole amount of such payments shall be made and not merely the excess).

2.6 The Purchaser shall pay to the Seller, by way of fixed deferred consideration (the Fixed Deferred Consideration), the amount of US$30 million to be paid as follows:-

(a) US$2.5 million on the Closing Date;

(b) US$2.5 million on the later of 1 April 2008 and the Closing Date (in addition to the amount payable under sub-clause (a));

(d) US$2.5 million on each of 1 January, 1 April, 1 July and 1 October 2009; and

(e) US$2.5 million on each of 1 January, 1 April, 1 July and 1 October 2010,

subject in each case to any provision of the Management Agreement.

2.7 The provisions of Schedule 7 shall apply in respect of the Earnout Consideration (which the Purchaser shall be obliged to pay in accordance with the provisions of Schedule 7) and the Total Consideration for the Shares shall consist of the aggregate of the Final Price, the Fixed Deferred Consideration and the total amount of Earnout Consideration paid by the Purchaser to the Seller.

2.8 The Total Consideration shall, to the extent applicable, be adopted for all tax reporting purposes. The allocation of the Total Consideration in relation to the Ekibastuz power plant and the Maikuben mine is attached at Schedule 10.

3. CONDITIONS TO CLOSING

(i) waivers by the Republic of Kazakhstan of any pre-emptive rights it may have in relation to the transfer of any direct or indirect interest in Maikuben West LLP and AES Ekibastuz LLP (or a letter or letters from the authorised body indicating that no pre-emptive right under Kazakh law is applicable to such transfers);

3.2 The Purchaser shall, at its own cost and subject to the due performance by the Seller of its obligations under clause 3.3 below, use its best endeavours to ensure that the Condition in clause 3.1(a) is fulfilled as soon as reasonably practicable after the date of this Agreement.

The Purchaser shall for this purpose:

(a) promptly notify the Seller (and provide copies or, in the case of non-written communications, details) of any communications with any such Governmental Entity relating to any such consent, approval or action;

(b) regularly review with the Seller the progress of any notifications or filings with a view to obtaining clearance from any Governmental Entity at the earliest reasonable opportunity; and

3.4 Subject to the due performance by the Purchaser of its obligations under clauses 3.2 above and 6.1 below and to all consents or approvals contemplated by such clauses having been obtained, the Seller shall, at its own cost, use its best endeavours to ensure that the Condition in clause 3.1(b) is fulfilled as soon as reasonably practicable after such consents and approvals have been obtained.

3.5 The Conditions may only be waived by the written agreement of the Seller and the Purchaser.

3.6 The Seller and the Purchaser shall each notify the other promptly upon becoming aware that any Condition has been fulfilled. The first Business Day in London on or by which all the Conditions have been fulfilled (or waived in accordance with clause 3.5) is the Unconditional Date.

3.7 If:

(a) Closing has not occurred on or before 11 April 2008; or

(b) any Governmental Entity has rejected, such decision being in full legal force and subject to no further right of appeal, any application for the granting of any statutory, regulatory or other consent, licence or authorisation set out in clause 3.1(a) above or has made, such decision being in full legal force and subject to no further right of appeal, such grant subject to conditions that the Purchaser or the Seller in its reasonably held view considers unacceptable,

then this Agreement (other than the Surviving Provisions) shall automatically terminate unless the parties agree otherwise in writing. In such event, neither party (nor any of its Affiliates) shall have any claim under this Agreement of any nature whatsoever against the other party (or any of its Affiliates) except in respect of any rights and liabilities which have accrued before termination or under any of the Surviving Provisions.

4.3 At Closing each of the Seller and the Purchaser shall deliver or perform (or ensure that there is delivered or performed) all those documents, items and actions respectively listed in relation to that party or any of its Affiliates in Schedule 4.

4.4 If for any reason the Unconditional Date has occurred and the provisions of Part B of Schedule 4 are not fully observed and performed as contemplated by this Agreement, the Purchaser may elect (in addition and without prejudice to all other rights or remedies available to it) not to complete the purchase of the Shares or to fix a new time and date for Closing by, in either case, giving notice to the Seller. In particular, the Purchaser shall not be obliged to complete the purchase of any of the Shares unless the purchase of all the Shares is completed simultaneously in accordance with this Agreement. If for any reason the

Unconditional Date has occurred and the provisions of Part C of Schedule 4 are not fully observed and performed as contemplated by this Agreement, the Seller may elect (in addition and without prejudice to all other rights and remedies available to it) not to complete the sale of the Shares or to fix a new time and date for Closing by, in either case, giving notice to the Purchaser. In particular, the Seller shall not be obliged to complete the sale of any of the Shares unless the sale of all the Shares is completed simultaneously in accordance with this Agreement.

(a) except for the Surviving Provisions, all the provisions of this Agreement shall lapse and cease to have effect, provided that neither the lapsing of those provisions nor their ceasing to have effect shall affect any accrued rights or liabilities of either party in respect of damages for non-performance of any obligation under this Agreement falling due for performance prior to such lapse and cessation; and

5. INDEMNITY IN RESPECT OF CONSENTS

5.1 The Purchaser shall indemnify the Seller against any and all Costs suffered or incurred by the Seller and each of its Affiliates to the extent that Closing occurs and any such Costs subsequently arise or result in Kazakhstan as a result of any of the statutory, regulatory and other consents, licences or authorisations of any Governmental Entity contemplated by the Condition in clause 3.1(a) as well as by clause 6.1(a) below not having been obtained (or, if obtained, being in any way insufficient or defective) (other than in respect of any such Costs which relate to consents, licences or authorisations required solely in connection with the step contemplated at point (i) on page 7 of Exhibit 5).

5.2 The provisions of clause 5.1 above shall not apply to the extent that such Costs arise as a direct result of any incorrect or otherwise defective written information or documents provided by or on behalf of the Seller to the Purchaser for the purpose of obtaining such consents, licences or authorisations (for the avoidance of doubt, such information shall include the description of the Reorganisation contained in Exhibit 5).

23. WHOLE AGREEMENT

23.1 In this clause 23 the Relevant Parties shall mean the Seller and the Purchaser, and each of them shall be a Relevant Party.

23.2 This Agreement and the other Transaction Documents together set out the whole agreement between the Relevant Parties in respect of the sale and purchase of the Shares and supersede any prior agreement (whether oral or written) relating to the Proposed Transactions. It is agreed that:

Such an opinion shall set out the facts on which such an opinion is based. If the Seller does not agree with the facts stated in such opinion, it may make written representations to the issuer of the opinion, who shall consider such representations and revise the opinion as necessary. For the avoidance of doubt, the amount that the Purchaser may set off in such manner shall not exceed 20% of the Final Price.

24.2 In the event that the Seller exercises its right of termination pursuant to clause 8.1 of the Management Agreement or the Parent Company exercises its right of termination pursuant to clause 8.2 of the Management

Agreement prior to 31 January 2009, the Seller shall procure that a person satisfying the criteria set out in clause 14.1 of the Management Agreement provides a guarantee of the Seller’s financial obligations under this Agreement. Such guarantee shall be limited to the amount paid to the Seller pursuant to clause 8.1 of the Management Agreement (if the Seller exercises its right of termination) or the amount that would have been paid to the Seller if it had exercised its right of termination (if the Purchaser exercises its right of termination) (but in any event shall not exceed 20% of the Final Price) and shall expire on 31 January 2009 (or, if later, upon the settlement in full by the Seller of the Claim) provided that the Claim is notified to the Seller prior to 31 January 2009 and provided that the Purchaser has first delivered (or shall deliver no later than 10 Business Days after such termination of the Management Agreement) to the Seller an External Counsel Opinion).

26. WAIVERS, RIGHTS AND REMEDIES

No single or partial exercise of any such right or remedy shall preclude any further exercise of it or the exercise of any other remedy.

Each of the provisions of this Agreement and the other Transaction Documents is severable. If any such provision is held to be or becomes invalid or unenforceable in any respect under the law of any jurisdiction, it shall have no effect in that respect and the parties shall use all reasonable efforts to replace it in that respect with a valid and enforceable substitute provision the effect of which is as close to its intended effect as possible.

10. No liability for Claims arising from acts or omissions of Purchaser. The Seller shall not be liable for any Claim to the extent that it would not have arisen but for, or has been increased or not reduced as a result of, any voluntary act, omission or transaction carried out:

(b)		before Closing by any member of the Seller Group or any Group Company at the direction or request of the Purchaser or any member of the Purchaser Group.
