Delivery of this letter of transmittal to an address, or transmission via telegram, telex or facsimile, other than to the exchange agent as set forth above, will not constitute a valid delivery. The method of delivery of all documents, including certificates, is at the risk of the holder. Instead of delivery by mail, we recommend that holders use an overnight or hand delivery service. If delivery is by mail, we recommend the use of registered or certified mail with return receipt requested, properly insured. You should read the instructions accompanying this letter of transmittal carefully before you complete this letter of transmittal.

The undersigned acknowledges that he or she has received the prospectus dated , 2007 of The AES Corporation ("AES") and this letter of transmittal and the instructions hereto, which together constitute AES's offer to exchange $500,000,000 aggregate principal amount of unregistered 7.75% Senior Notes due 2015 and $1,500,000,000 aggregate principal amount of unregistered 8.0%

Senior Notes due 2017 for an equal principal amount of 7.75% Senior Notes due 2015 and 8.0% Senior Notes due 2017, which are registered under the Securities Act of 1933, as amended (the "Securities Act"), respectively, each pursuant to a registration statement of which the prospectus is a part. The outstanding unregistered 7.75% Senior Notes due 2015 have CUSIP numbers 00130H BJ3 or U0080R AK6 and the outstanding unregistered 8.0% Senior Notes due 2017 have CUSIP numbers 00130H BF1 or U0080R AJ9.

The term "Expiration Date" shall mean 12:00 p.m., midnight, New York City time, on , 2008, unless The AES Corporation, in its sole discretion, extends the exchange offer, in which case the term shall mean the latest date and time to which the exchange offer is extended. Whenever we refer to the 7.75% Senior Notes due 2015 registered under the Securities Act and the 8.0% Senior Notes due 2017 registered under the Securities Act, we will refer to them as the "exchange notes." Whenever we refer to the unregistered 7.75% Notes due 2015 or the unregistered 8.0% Senior Notes due 2017, we will refer to them as the "unregistered notes." All other terms used but not defined herein have the meaning given to them in the prospectus.

Delivery of this letter of transmittal and any other required documents must be made to the exchange agent.

Delivery of documents to The Depository Trust Company ("DTC"), the Euroclear System ("Euroclear") or Clearstream Banking, Société Anonyme ("Clearstream Luxembourg") does not constitute delivery to the exchange agent.

The term "Holder" as used herein means any person in whose name unregistered notes are registered on The AES Corporation's agent's books or any other person who has obtained a properly completed bond power from the registered holder, or any person whose unregistered notes are held of record by DTC, Euroclear or Clearstream Luxembourg who desires to deliver such unregistered notes by book-entry transfer at DTC, Euroclear or Clearstream Luxembourg, as the case may be.

Any Holder of unregistered notes who wishes to tender his, her or its unregistered notes must, prior to the Expiration Date, either: (a) complete, sign and deliver this letter of transmittal, or a facsimile thereof, to the exchange agent in person or to the address or facsimile number set forth above and tender (and not withdraw) his, her or its unregistered notes, or (b) if a tender of unregistered notes is to be made by book-entry transfer to the account maintained by the exchange agent at DTC, Euroclear or Clearstream Luxembourg confirm such book-entry transfer, including the delivery of an agent's message (a "Book-Entry Confirmation"), in each case in accordance with the procedures for tendering described in the instructions to this letter of transmittal.

(See Instruction 1.)

Upon the terms and subject to the conditions of the exchange offer, the acceptance for exchange of the unregistered notes validly tendered and not withdrawn and the issuance of the exchange notes will be made promptly following the Expiration Date.

Subject to the terms and conditions of the exchange offer, the undersigned hereby tenders to AES the principal amount of unregistered notes indicated above. Subject to and effective upon the acceptance for exchange of the principal amount of unregistered notes tendered hereby in accordance with this letter of transmittal and the accompanying instructions, the undersigned sells, assigns and transfers to, or upon the order of, AES all right, title and interest in and to the unregistered notes tendered hereby. The undersigned hereby irrevocably constitutes and appoints the exchange agent its agent and attorney-in-fact (with full knowledge that the exchange agent also acts as agent of AES and as trustee under the indenture for the unregistered notes and the exchange notes) with respect to the tendered unregistered notes with full power of substitution to (i) deliver certificates for such unregistered notes to AES, or transfer ownership of such unregistered notes on the account books maintained by DTC, Euroclear or Clearstream Luxembourg, together with all accompanying evidences of transfer and authenticity to, or upon the order of, AES and (ii) present such unregistered notes for transfer on the books of AES and receive all benefits and otherwise exercise all rights of beneficial ownership of such unregistered notes, all in accordance with the terms of the exchange offer. The power of attorney granted in this paragraph shall be deemed irrevocable and coupled with an interest.

The undersigned hereby represents and warrants that he or she has full power and authority to tender, exchange, sell, assign and transfer the unregistered notes tendered hereby and to acquire the exchange notes issuable upon the exchange of the unregistered notes, and that AES will acquire good and unencumbered title thereto, free and clear of all liens, restrictions, charges and encumbrances and not subject to any adverse claim, when the same are acquired by AES. The undersigned also acknowledges that this exchange offer is being made in reliance upon an interpretation by the staff of the Securities and Exchange Commission (the "SEC") that the exchange notes issued in exchange for the unregistered notes pursuant to the exchange offer may be offered for sale, resold and otherwise transferred by holders thereof (other than a broker-dealer who purchased such unregistered notes directly from AES for resale pursuant to Rule 144A or any other available exemption under the Securities Act or a holder that is an "affiliate" of AES as defined in Rule 405 under the Securities Act) without compliance with the registration and prospectus delivery provisions of the Securities Act, provided that such exchange notes are acquired by a non-affiliate in the ordinary course of such holder's business and such holders have no arrangement or understanding with any person to participate in the distribution of such exchange notes.

The undersigned Holder represents and warrants that

(a): the exchange notes acquired pursuant to the exchange offer are being acquired in the ordinary course of business of the person receiving the exchange notes, whether or not the person is the Holder;
(b): neither the undersigned Holder nor any other recipient of the exchange notes (if different than the Holder) is engaged in, intends to engage in, or has any arrangement or understanding with any person to participate in, the distribution of the unregistered notes or exchange notes;
(c): neither the undersigned Holder nor any other recipient is an "affiliate" of AES as defined in Rule 405 promulgated under the Securities Act or, if the Holder or such recipient is an affiliate, that the Holder or such recipient will comply with the registration and prospectus delivery requirements of the Securities Act to the extent applicable;
(d): if the undersigned is a broker-dealer, it has not entered into any arrangement or understanding with AES or any "affiliate" of AES as defined in Rule 405 promulgated under the Securities Act to distribute the exchange notes;

(e): if the undersigned is a broker-dealer, the undersigned further represents and warrants that, if it will receive exchange notes for its own account in exchange for unregistered notes that were acquired as a result of market-making activities or other trading activities, the undersigned will deliver a prospectus meeting the requirements of the Securities Act (for which purposes, the delivery of the prospectus, as the same may be hereafter supplemented or amended, shall be sufficient) in connection with any resale of exchange notes received in the exchange offer; and
(f): the undersigned Holder is not acting on behalf of any person or entity that could not truthfully make these representations.

By acknowledging that you, as such a broker-dealer, will deliver and by delivering a prospectus meeting the requirements of the Securities Act in connection with any resale of exchange notes, you will not be deemed to admit that you are an "underwriter" within the meaning of the Securities Act.

The undersigned will, upon request, execute and deliver any additional documents deemed by the exchange agent or AES to be necessary or desirable to complete the exchange, assignment and transfer of the unregistered notes tendered hereby or transfer of ownership of such unregistered notes on the account books maintained by a book-entry transfer facility.

The undersigned understands and agrees that AES reserves the right not to accept tendered unregistered notes from any tendering Holder if AES determines, in its sole and absolute discretion, that its ability to proceed with the exchange offer would be impaired by a pending action or proceeding with respect to the exchange offer or that such acceptance could result in a violation of applicable securities laws.

For purposes of the exchange offer, AES shall be deemed to have accepted validly tendered unregistered notes when, as and if AES has given oral (promptly confirmed in writing) or written notice thereof to the exchange agent. If any tendered unregistered notes are not accepted for exchange pursuant to the exchange offer for any reason, such unaccepted or non-exchanged unregistered notes will be returned to the address shown below or to a different address as may be indicated herein under "Special Delivery Instructions," without expense to the tendering Holder thereof, (or, in the case of tender by book-entry transfer into the exchange agent's account at the book-entry transfer pursuant to the book-entry transfer procedures described in the prospectus under the "The Exchange Offer—Book-Entry Transfer," such non-exchanged notes will be credited to an account maintained with such book-entry transfer facility) facility promptly after the expiration or termination of the exchange offer.

The undersigned understands and acknowledges that AES reserves the right in its sole discretion to purchase or make offers for any unregistered notes that remain outstanding subsequent to the Expiration Date or, as set forth in the prospectus under the caption "The Exchange Offer—Expiration Date; Extensions; Amendment; Termination," to terminate the exchange offer and, to the extent permitted by applicable law, purchase unregistered notes in the open market, in privately negotiated transactions or otherwise. The terms of any such purchases or offers could differ from the terms of the exchange offer.

The undersigned understands that tenders of unregistered notes pursuant to the procedures described under the caption "The Exchange Offer—Procedures for Tendering" in the prospectus and in the instructions hereto will constitute a binding agreement between the undersigned and AES upon the terms and subject to the conditions of the exchange offer. The undersigned also agrees that acceptance of any tendered unregistered notes by AES and the issuance of exchange notes in exchange therefor shall constitute performance in full by The AES Corporation of its obligations under the exchange offer and Registration Rights Agreement and that, upon the issuance of the exchange notes, AES will have no further obligations or liabilities thereunder (except in certain limited circumstances).

All authority conferred or agreed to be conferred by this letter of transmittal shall survive the death, incapacity or dissolution of the undersigned and every obligation under this letter of transmittal

shall be binding upon the undersigned's heirs, personal representatives, successors and assigns. This tender may be withdrawn only in accordance with the procedures set forth in the prospectus and in this letter of transmittal.

By acceptance of the exchange offer, each broker-dealer that receives exchange notes pursuant to the exchange offer hereby acknowledges and agrees that, upon the receipt of notice by AES of the happening of any event that makes any statement in the prospectus untrue in any material respect or that requires the making of any changes in the prospectus in order to make the statements therein not misleading (which notice AES agrees to deliver promptly to such broker-dealer), such broker-dealer will suspend use of the prospectus until AES has amended or supplemented the prospectus to correct such misstatement or omission and has furnished copies of the amended or supplemented prospectus to such broker-dealer.

Unless otherwise indicated under "Special Registration Instructions," please issue the certificates representing the exchange notes issued in exchange for the unregistered notes accepted for exchange and return any unregistered notes not tendered or not exchanged, in the name(s) of the undersigned (or in either such event in the case of unregistered notes tendered by DTC, Euroclear or Clearstream Luxembourg, by credit to the respective account at DTC, Euroclear or Clearstream Luxembourg. Similarly, unless otherwise indicated under "Special Delivery Instructions," please send the certificates representing the exchange notes issued in exchange for the unregistered notes accepted for exchange and return any unregistered notes not tendered or not exchanged (and accompanying documents, as appropriate) to the undersigned at the address shown below the undersigned's signatures, unless, in either event, tender is being made through DTC, Euroclear or Clearstream Luxembourg. In the event that both "Special Registration Instructions" and "Special Delivery Instructions" are completed, please issue the certificates representing the exchange notes issued in exchange for the unregistered notes accepted for exchange and return any unregistered notes not tendered or not exchanged in the name(s) of, and send said certificates to, the person(s) so indicated. The undersigned recognizes that AES has no obligations pursuant to the "Special Registration Instructions" and "Special Delivery Instructions" to transfer any unregistered notes from the name of the registered holder(s) thereof if AES does not accept for exchange any of the unregistered notes so tendered.

Holders who wish to tender the unregistered notes and (1) whose unregistered notes are not immediately available or (2) who cannot deliver their unregistered notes, this letter of transmittal or any other documents required hereby to the exchange agent prior to the expiration date may tender their unregistered notes according to the guaranteed delivery procedures set forth in the prospectus under the caption "The Exchange Offer—Guaranteed Delivery Procedures."

INSTRUCTIONS

Forming part of the terms and conditions
of the exchange offer

1. Guarantee of Signatures. Signatures on this letter of transmittal (or copy hereof) or a notice of withdrawal, as the case may be, must be guaranteed by a member firm of a registered national securities exchange or of the Financial Industry Regulatory Authority, a commercial bank or trust company having an office or correspondent in the United States or an "eligible guarantor institution" within the meaning of Rule 17Ad-15 under the Exchange Act (an "Eligible Institution") unless the unregistered notes tendered pursuant thereto are tendered (i) by a registered Holder (including any participant in DTC, Euroclear or Clearstream Luxembourg whose name appears on a security position listing as the owner of unregistered notes) who has not completed the box set forth herein entitled "Special Registration Instructions" or "Special Delivery Instructions" of this letter of transmittal or (ii) for the account of an Eligible Institution.

2. Delivery of this Letter of Transmittal and Unregistered Notes. Certificates for the physically tendered unregistered notes (or a confirmation of a book-entry transfer to the exchange agent at DTC, Euroclear or Clearstream Luxembourg of all unregistered notes tendered electronically), as well as, in the case of physical delivery of unregistered notes, a properly completed and duly executed copy of this letter of transmittal or facsimile hereof and any other documents required by this letter of transmittal must be received by the exchange agent at its address set forth herein prior to 12:00 p.m., midnight, New York City time, on the Expiration Date. The method of delivery of the tendered unregistered notes, this letter of transmittal and all other required documents, or book-entry transfer and transmission of an Agent's Message (as defined below) by a DTC, Euroclear or Clearstream Luxembourg participant, to the exchange agent are at the election and risk of the Holder and, except as otherwise provided below, the delivery will be deemed made only when actually received by the exchange agent. Instead of delivery by mail, it is recommended that the Holder use an overnight or hand delivery service. In all cases, sufficient time should be allowed to assure timely delivery. No letter of transmittal or unregistered notes should be sent to AES or DTC, Euroclear or Clearstream Luxembourg.

The exchange agent will make a request to establish an account with respect to the unregistered notes at DTC, Euroclear or Clearstream Luxembourg for purposes of the exchange offer promptly after receipt of the prospectus, and any financial institution that is a participant in DTC, Euroclear or Clearstream Luxembourg may make book-entry delivery of unregistered notes by causing DTC, Euroclear or Clearstream Luxembourg to transfer such unregistered notes into the exchange agent's account at DTC, Euroclear or Clearstream Luxembourg in accordance with the relevant entity's procedures for transfer. However, although delivery of unregistered notes may be effected through book-entry transfer at DTC, Euroclear or Clearstream Luxembourg, an Agent's Message (as defined in the next paragraph) in connection with a book-entry transfer and any other required documents must, in any case, be transmitted to and received by the exchange agent at the address specified on the cover page of the letter of transmittal on or prior to the Expiration Date or the guaranteed delivery procedures described below must be complied with.

A Holder may tender unregistered notes that are held through DTC by transmitting its acceptance through DTC's Automatic Tender Offer Program, for which the transaction will be eligible, and DTC will then edit and verify the acceptance and send an Agent's Message to the exchange agent for its acceptance. Any participant in Euroclear or Clearstream Luxembourg may make book-entry delivery of unregistered notes by causing Euroclear or Clearstream Luxembourg to transfer such unregistered notes into the exchange agent's account in accordance with established Euroclear or Clearstream Luxembourg procedures for transfer. The exchange for tendered unregistered notes will only be made after a timely confirmation of a book-entry transfer of the unregistered notes into the exchange agent's account, and timely receipt by the exchange agent of an Agent's Message. The term "Agent's Message"

means a message transmitted by DTC, Euroclear or Clearstream Luxembourg, as the case may be, and received by the exchange agent and forming part of the Book-Entry Confirmation, which states that DTC, Euroclear or Clearstream Luxembourg, as the case may be, has received an express acknowledgment from a participant in DTC, Euroclear or Clearstream Luxembourg tendering the unregistered notes and that such participant has received the letter of transmittal and agrees to be bound by the terms of the letter of transmittal and AES may enforce such agreement against such participant. Delivery of an Agent's Message will also constitute an acknowledgment from the tendering DTC, Euroclear or Clearstream Luxembourg participant, as the case may be, that the representations and warranties set forth on pages 4 and 5 of this letter of transmittal are true and correct.

Holders of unregistered notes held through Euroclear or Clearstream Luxembourg are required to use book-entry transfer pursuant to the standard operating procedures of Euroclear or Clearstream Luxembourg, as the case may be, to accept the exchange offer and to tender their unregistered notes. A computer-generated message must be transmitted to Euroclear or Clearstream Luxembourg, as the case may be, in lieu of a letter of transmittal, in order to tender the unregistered notes in the exchange offer.

Holders who wish to tender their unregistered notes and (i) whose unregistered notes are not immediately available or (ii) who cannot deliver their unregistered notes, this letter of transmittal or any other documents required hereby to the exchange agent prior to the Expiration Date, or who cannot complete the procedure for book-entry transfer on a timely basis must tender their unregistered notes and follow the guaranteed delivery procedures set forth in the prospectus. Pursuant to such procedures: (i) such tender must be made through an Eligible Institution (as defined above) (ii) prior to the Expiration Date, the exchange agent must have received from the Eligible Institution a properly completed and duly executed notice of guaranteed delivery (by facsimile transmission, mail or hand delivery) (or a properly transmitted Agent's Message in lieu of notice of guaranteed delivery) setting forth the name and address of the Holder of the unregistered notes, the certificate number or numbers of such unregistered notes and the principal amount of unregistered notes tendered, stating that the tender is being made thereby and guaranteeing that within three (3) business days after the Expiration Date, this letter of transmittal (or copy thereof) together with the certificate(s) representing the unregistered notes (or a confirmation of electronic mail delivery or book-entry delivery into the exchange agent's account at DTC, Euroclear or Clearstream Luxembourg) and any of the required documents will be deposited by the Eligible Institution with the exchange agent and (iii) such properly completed and executed letter of transmittal (or copy thereof), as well as all other documents required by this letter of transmittal and the certificate(s) representing all tendered unregistered notes in proper form for transfer or a confirmation of electronic mail delivery or book-entry delivery into the exchange agent's account at DTC, Euroclear or Clearstream Luxembourg, must be received by the exchange agent within three (3) business days after the Expiration Date, all as provided in the prospectus under the caption "The Exchange Offer—Guaranteed Delivery Procedures." Any Holder of unregistered notes who wishes to tender his unregistered notes pursuant to the guaranteed delivery procedures described above must ensure that the exchange agent receives the notice of guaranteed delivery prior to 12:00 p.m., midnight, New York City time, on the Expiration Date. Upon request to the exchange agent, a notice of guaranteed delivery will be sent to Holders who wish to tender their unregistered notes according to the guaranteed delivery procedures set forth above.

All questions as to the validity, form, eligibility (including time of receipt), acceptance and withdrawal of tendered unregistered notes or this letter of transmittal will be determined by AES in its sole discretion, which determination will be final and binding. All tendering Holders, by execution of this letter of transmittal (or copy hereof), shall waive any right to receive notice of the acceptance of the unregistered notes for exchange. AES reserves the absolute right to reject any and all unregistered notes or letter of transmittal not properly tendered or any tenders AES's acceptance of which would, in the opinion of counsel for AES, be unlawful. The AES Corporation also reserves the absolute right to waive any defects, irregularities or conditions of tender as to particular unregistered notes. AES's

interpretation of the terms and conditions of the exchange offer (including the instructions in this letter of transmittal) will be final and binding on all parties. Unless waived, any defects or irregularities in connection with tenders of unregistered notes must be cured within such time as AES shall determine. Although AES intends to notify Holders of defects or irregularities with respect to tenders of unregistered notes, none of AES, the exchange agent or any other person shall be under any duty to give notification of defects or irregularities with respect to tenders of unregistered notes, nor shall any of them incur any liability for failure to give such notification. Tenders of unregistered notes will not be deemed to have been made until such defects or irregularities have been cured or waived. Any unregistered notes received by the exchange agent that are not properly tendered and as to which the defects or irregularities have not been cured or waived will be returned by the exchange agent to the tendering Holders of unregistered notes, unless otherwise provided in this letter of transmittal, as soon as practicable following the Expiration Date.

3. Inadequate Space. If the space provided is inadequate, the certificate numbers and/or the number of the unregistered notes should be listed on a separate signed schedule attached hereto.

4. Tender by Holder. Except in limited circumstances, only a registered Holder of unregistered notes or a DTC, Euroclear or Clearstream Luxembourg participant listed on a securities position listing furnished by DTC, Euroclear or Clearstream Luxembourg with respect to the unregistered notes may tender its unregistered notes in the exchange offer. Any beneficial owner of unregistered notes who is not the registered Holder and is not a DTC, Euroclear or Clearstream Luxembourg participant and who wishes to tender should arrange with such registered holder to execute and deliver this letter of transmittal on such beneficial owner's behalf or must, prior to completing and executing this letter of transmittal and delivering his, her or its unregistered notes, either make appropriate arrangements to register ownership of the unregistered notes in such beneficial owner's name or obtain a properly completed bond power from the registered holder or properly endorsed certificates representing such unregistered notes.

5. Partial Tenders; Withdrawals. Tenders of unregistered notes will be accepted only in integral multiples of $1,000. If less than the entire principal amount of any unregistered notes is tendered, the tendering Holder should fill in the principal amount tendered in the fourth column of the chart entitled "Description of Unregistered Notes." The entire principal amount of unregistered notes delivered to the exchange agent will be deemed to have been tendered unless otherwise indicated. If the entire principal amount of all unregistered notes is not tendered, unregistered notes for the principal amount of unregistered notes not tendered and a certificate or certificates representing exchange notes issued in exchange of any unregistered notes accepted will be sent to the Holder at his or her registered address, unless a different address is provided in the appropriate box on this letter of transmittal or unless tender is made through DTC, Euroclear or Clearstream Luxembourg promptly after the unregistered notes are accepted for exchange.

Except as otherwise provided herein, tenders of unregistered notes may be withdrawn at any time prior to the Expiration Date. To withdraw a tender of unregistered notes in the exchange offer, a written or facsimile transmission notice of withdrawal must be received by the exchange agent at its address set forth herein prior to the Expiration Date. For DTC, Euroclear or Clearstream Luxembourg participants, Holders must comply with their respective standard operating procedures for electronic tenders and the exchange agent must receive an electronic notice of withdrawal from DTC, Euroclear or Clearstream Luxembourg. Any such notice of withdrawal must (1) specify the name of the person having deposited the unregistered notes to be withdrawn (the "Depositor"), (2) identify the unregistered notes to be withdrawn (including the certificate number or numbers and principal amount of such unregistered notes, or, in the case of unregistered notes transferred by book-entry transfer, the name and number of the account at DTC, Euroclear or Clearstream Luxembourg to be credited), (3) be signed by the Depositor in the same manner as the original signature on the letter of transmittal by which such unregistered notes were tendered (including any required signature guarantees) or be

accompanied by documents of transfer sufficient to have the registrar with respect to the unregistered notes register the transfer of such unregistered notes into the name of the person withdrawing the tender and (4) specify the name in which any such unregistered notes are to be registered, if different from that of the Depositor. All questions as to the validity, form and eligibility (including time of receipt) of such notices will be determined by AES, whose determination shall be final and binding on all parties. Any unregistered notes so withdrawn will be deemed not to have been validly tendered for purposes of the exchange offer and no exchange notes will be issued with respect thereto unless the unregistered notes so withdrawn are validly re-tendered. Any unregistered notes which have been tendered but which are not accepted for exchange by AES will be returned to the Holder thereof without cost to such Holder as soon as practicable after withdrawal, rejection of tender or termination of the exchange offer. Properly withdrawn unregistered notes may be re-tendered by following one of the procedures described in the prospectus under "The Exchange Offer—Procedures for Tendering" at any time prior to the Expiration Date.

6. Signatures on the Letter of Transmittal; Bond Powers and Endorsements. If this letter of transmittal (or a copy hereof) is signed by the registered Holder(s) of the unregistered notes tendered hereby, the signature must correspond with the name(s) as written on the face of the unregistered notes without alteration, enlargement or any change whatsoever.

If any of the unregistered notes tendered hereby are owned of record by two or more joint owners, all such owners must sign this letter of transmittal.

If a number of unregistered notes registered in different names are tendered, it will be necessary to complete, sign and submit as many copies of this letter of transmittal as there are different registrations of unregistered notes.

If this letter of transmittal (or a copy hereof) is signed by the registered Holder(s) (which term, for the purposes described herein, shall include a book-entry transfer facility whose name appears on the security listing as the owner of the unregistered notes) of unregistered notes tendered and the certificate(s) for exchange notes issued in exchange therefor is to be issued (or any untendered principal amount of unregistered notes is to be reissued) to the registered Holder, such Holder need not and should not endorse any tendered unregistered note, nor provide a separate bond power. In any other case, such Holder must either properly endorse the unregistered notes tendered or transmit a properly completed separate bond power with this letter of transmittal, with the signatures on the endorsement or bond power guaranteed by an Eligible Institution.

If this letter of transmittal (or a copy hereof) is signed by a person other than the registered Holder(s) of unregistered notes listed therein, such unregistered notes must be endorsed or accompanied by properly completed bond powers which authorize such person to tender the unregistered notes on behalf of the registered Holder, in either case signed as the name of the registered Holder or Holders appears on the unregistered notes.

If this letter of transmittal (or a copy hereof) or any unregistered notes or bond powers are signed by trustees, executors, administrators, guardians, attorneys-in-fact, or officers of corporations or others acting in a fiduciary or representative capacity, such persons should so indicate when signing, and, unless waived by AES, evidence satisfactory to AES of their authority to so act must be submitted with this letter of transmittal.

Endorsements on unregistered notes or signatures on bond powers required by this Instruction 6 must be guaranteed by an Eligible Institution.

7. Special Registration and Delivery Instructions. Tendering Holders should indicate, in the applicable spaces, the name and address to which exchange notes or substitute unregistered notes for principal amounts not tendered or not accepted for exchange are to be issued or sent, if different from the name and address of the person signing this letter of transmittal (or in the case of tender of the unregistered notes through DTC, Euroclear or Clearstream Luxembourg, if different from the account

maintained at DTC, Euroclear or Clearstream Luxembourg indicated above). In the case of issuance in a different name, the taxpayer identification or social security number of the person named must also be indicated.

8. Transfer Taxes. AES will pay all transfer taxes, if any, applicable to the exchange of unregistered notes pursuant to the exchange offer. If, however, certificates representing exchange notes or unregistered notes for principal amounts not tendered or accepted for exchange are to be delivered to, or are to be registered or issued in the name of, any person other than the registered Holder of the unregistered notes tendered hereby, or if tendered unregistered notes are registered in the name of any person other than the person signing this letter of transmittal, or if a transfer tax is imposed for any reason other than the exchange of unregistered notes pursuant to the exchange offer, then the amount of any such transfer taxes (whether imposed on the registered Holder or any other person) will be payable by the tendering Holder. If satisfactory evidence of payment of such taxes or exemption therefrom is not submitted with this letter of transmittal, the amount of such transfer taxes will be billed directly to such tendering Holder.

Except as provided in this Instruction 8, it will not be necessary for transfer tax stamps to be affixed to the unregistered notes listed in this letter of transmittal.

9. Waiver of Conditions. AES reserves the right, in its sole discretion, to amend, waive or modify specified conditions in the exchange offer in the case of any unregistered notes tendered.

10. Mutilated, Lost, Stolen or Destroyed Unregistered Notes. Any tendering Holder whose unregistered notes have been mutilated, lost, stolen or destroyed should contact the exchange agent at the address indicated herein for further instruction.

11. Requests for Assistance or Additional Copies. Questions and requests for assistance and requests for additional copies of the prospectus or this letter of transmittal may be directed to the exchange agent at the address specified in the prospectus. Holders may also contact their broker, dealer, commercial bank, trust company or other nominee for assistance concerning the exchange offer.

IMPORTANT TAX INFORMATION

A tendering Holder of the unregistered notes who is a U.S. person is generally required to give the exchange agent such Holder's social security number or employer identification number ("TIN") or establish a basis for exemption from backup withholding. If the unregistered notes are in more than one name or are not in the name of the actual owner, consult the enclosed Guidelines for Certification of Taxpayer Identification Number on Substitute Form W-9 for additional guidance on which number to report.

Certain tendering Holders (including, among others, all corporations and certain foreign persons) are not subject to these backup withholding and reporting requirements. Exempt Holders should indicate their exempt status on Substitute Form W-9. A foreign person may qualify as an exempt recipient by submitting to the exchange agent a properly completed Internal Revenue Service Form W-8BEN, signed under penalties of perjury, attesting to that Holder's exempt status. A Form W-8BEN can be obtained from the exchange agent. See the enclosed "Guidelines for Certification of Taxpayer Identification Number on Substitute Form W-9" for additional instructions.

A Holder shall write "applied for" in the box in Part 1 of the form if the tendering Holder has not been issued a TIN and has applied for a TIN or intends to apply for a TIN in the near future. If "applied for" is written in the box in Part 1 and the exchange agent is not provided with a TIN within 60 days thereafter, the exchange agent will withhold 28% on all payments under the notes until a TIN is provided to the exchange agent.

(2): Circle the minor's name and furnish the minor's social security number.
(3): You must show your individual name, but you may also enter your business or "doing business as" name. You may use either your social security number or employer identification number (if you have one).
(4): List first and circle the name of the legal trust, estate, or pension trust. Do not furnish the identifying number of the personal representative or trustee unless the legal entity itself is not designated in the account title.

Payments of interest not generally subject to backup withholding include the following:

•: Payments on tax-free covenant bonds under section 1451 of the Code.
•: Payments made by certain foreign organizations.
•: Mortgage interest payments paid to you.

Exempt payees described above should file Form W-9 to avoid possible erroneous backup withholding. FILE THIS FORM WITH THE PAYER, FURNISH YOUR TAXPAYER IDENTIFICATION NUMBER, WRITE "EXEMPT" ON THE FACE OF THE FORM, SIGN AND DATE THE FORM AND RETURN IT TO THE PAYER. IF YOU ARE A NON-RESIDENT ALIEN OR A FOREIGN ENTITY NOT SUBJECT TO BACKUP WITHHOLDING, FILE WITH PAYER A COMPLETED IRS FORM W-8 (CERTIFICATE OF FOREIGN STATUS).

Certain payments other than interest, dividends, and patronage dividends, that are not subject to information reporting are also not subject to backup withholding. For details, see sections 6041, 6041A, 6045, 6050A and 6050N of the Code and the regulations promulgated thereunder.

Privacy Act Notice. Section 6109 of the Code requires most recipients of dividend, interest, or other payments to give TINs to payers who must report the payments to the IRS. The IRS uses the TINs for identification purposes. The IRS may also provide this information to the Department of Justice for civil and criminal litigation and to cities, states and the District of Columbia to carry out their tax laws. The IRS may also disclose this information to other countries under a tax treaty, to federal and state agencies to enforce federal nontax criminal laws, or to federal law enforcement and intelligence agencies to combat terrorism. Payers must be given the TINs whether or not recipients are required to file tax returns. Payers must generally withhold 28% of taxable interest, dividend, and certain other payments to a payee who does not furnish a taxpayer identification number to a payer. Certain penalties may also apply.

Penalties

(1): Penalty for Failure to Furnish Taxpayer Identification Number. If you fail to furnish your correct TIN to a payer, you are subject to a penalty of $50 for each such failure unless your failure is due to reasonable cause and not to willful neglect.
(2): Civil Penalty for False Information with Respect to Withholding. If you make a false statement with no reasonable basis which results in no imposition of backup withholding, you are subject to a penalty of $500.
(3): Criminal Penalty for Falsifying Information. Willfully falsifying certifications or affirmations may subject you to criminal penalties including fines and/or imprisonment.
