February 25, 2013, by and between ENERSIS S.A., a sociedad anónima abierta organized and existing under the laws of the Republic of Chile (the “Company”), and CITIBANK, N.A., a national banking association
organized under the laws of the United States of America acting solely in its capacity as ADS rights agent hereunder and having an office at 388 Greenwich Street, New York, New York 10013 (“Citibank”). 

WITNESSETH THAT: 
 WHEREAS, the Company is issuing transferable rights (the “Share Rights”) to holders (the “Shareholders”) of shares of its common stock (such shares of common
stock, the “Shares”, and such issuance, the “Issuance”), upon the terms and subject to the conditions to be described in a Prospectus Supplement (the “Prospectus Supplement”) to be dated on or about
February 25, 2013, supplementing the terms of that certain Prospectus, dated February 25, 2013 (the “Base Prospectus” and, together with the Prospectus Supplement, dated February 25, 2013, the
“Prospectus”). Each Share held as of record as of the Share Record Date (as defined below) shall receive a distribution of 0.504 transferable Share Rights, each Share Right entitling the holder thereof (the “Share Rights
Holder”) to purchase one (1) new Share (a “New Share”), as described in the Prospectus setting forth, inter alia, such offer to purchase New Shares (the “Share Rights Offer”); 

WHEREAS, the Issuance shall include the issuance of transferable rights (such rights, the “ADS Rights”) to
holders of Shares represented by American Depositary Shares (“ADSs” and such holders of ADSs, the “ADS Holders”) issued pursuant to the terms of the Second Amended and Restated Deposit Agreement, dated as of
September 30, 2010 (the “Deposit Agreement”), by and among the Company, Citibank, as Depositary (the “Depositary”), all Holders and Beneficial Owners (as defined in the Deposit Agreement) of ADSs issued
thereunder, each ADS representing fifty (50) Shares. Each ADS held as of record as of the Record Date (as defined below) shall receive a distribution of 0.504 transferable ADS Rights, each ADS Right entitling the holder thereof (the
“ADS Rights Holder”) to purchase one (1) new ADS (a “New ADS”) representing fifty (50) New Shares, as described in the Prospectus setting forth, inter alia, such offer to purchase New ADSs (the
“ADS Rights Offer” and, together with the Share Rights Offer, the “Rights Offer”); 

WHEREAS, the effectiveness of all subscriptions of Share Rights and ADSs Rights to purchase New Shares and New ADSs, respectively,
pursuant to the Rights Offer are conditioned on the subscription by Share Rights Holders and ADS Rights Holders (whether minority Shareholders or ADS Holders who receive the distribution of Share Rights or ADS Rights or a subsequent purchaser of
such Share Rights or ADS Rights) during the Rights Offer or during a subsequent offering to third party purchasers of at least 3,169,224,294 shares, which is the amount sufficient to permit Endesa S.A. to exercise its Share Rights to subscribe in
full and, after such exercise, not own more than 65% of the outstanding capital stock of the Company as provided under the Company’s Bylaws (the “Condition Precedent”). If the Condition Precedent is not satisfied, the
subscriptions of Share Rights and ADSs Rights to purchase New Shares and New ADSs, respectively, pursuant to the Rights Offer will be deemed not legally binding, and any subscription amounts tendered by any Share Rights Holder or any ADS Rights
Holder who exercised their Share Rights or ADS Rights, respectively, will be returned in full and the Capital Increase (as defined below) will be cancelled. 







 WHEREAS, upon satisfaction of the Condition Precedent and exercise of their
(i) Share Rights and payment of the Share Subscription Price (as defined below), Share Rights Holder will be issued New Shares in the amount subscribed for and (ii) ADS Rights and payment of the ADS Subscription Price (as defined below),
ADS Rights Holders will receive New ADSs in the amount subscribed for; and

Forms as soon as practicable after the date hereof and to cause to be destroyed any such ADS Subscription Forms that are not issued as a result of the initial issuance of ADS Rights and any transfer or assignment of all or a portion of the ADS
Rights in respect of which any such ADS Subscription Forms were prepared.

issuance of any ADS Subscription Form, as a result of any transfer or assignment of all or a portion thereof, to sign ADS Subscription Form by either the manual or the facsimile signature of a duly authorized officer of the Agent. Until the Agent

 a. On February 25, 2013 (i) Chadbourne & Parke LLP, U.S. counsel for the Company, will deliver to the Agent two (2) original copies of its legal opinion addressed to the Agent

Rights to which such ADS Record Date Holder is entitled pursuant to the ADS Rights Offer, as well as an instructions booklet substantially in the form set forth in Exhibit E attached
hereto (the “Instructions Booklet”) relating to, inter alia, the exercise and transfer of the ADS Subscription Form; and (B) a copy of the Prospectus, and (ii) by air mail (without registration or insurance) to each
ADS Record Date Holder having addresses outside the United States, of record (each an “Overseas Holder”) on the Record Date, the documents described in clause (i) above, unless otherwise directed in writing to the Agent by the
Company. Notwithstanding anything contained herein to the contrary, the Company hereby instructs the Agent to omit, and to instruct the Information Agent to omit, any ADS Record Date Holder having an address or record in Canada from any distribution
of the ADS Subscription Form or the Instruction Booklet. 
 (ii) On February 26, 2013, the Company will instruct the
Information Agent to distribute to DTC participants who held ADSs as of the Record Date sufficient copies (in the amounts requested by such DTC participants) of the following: (A) the Prospectus; (B) such broker letter substantially in the

February 26, 2013, the Agent will distribute to DTC, for credit to DTC participants as of the Record Date, the requisite number of ADS Rights (0.504 ADS Rights for every ADS held as of the Record Date). 

c. In the event that any ADS Subscription Form is returned to the Agent for any reason and proper delivery thereof cannot be effected on or prior to the
Expiration Date, the ADS Rights represented by such ADS Subscription Form will be void and will have no further value. The Agent will furnish to the Company such information as the Company may request with respect to any ADS Subscription Form that
cannot be delivered. The Agent shall cause the ADS Rights represented by ADS Subscription Forms not mailed to registered ADS Record Date Holders in accordance with Section 7(b) hereof, to be sold and the aggregate net proceeds of the sale of
all such ADS Rights (after subtraction of applicable fees of US$0.10 per ADS Right sold (equivalent to US$0.05 per ADS held)), expenses and applicable taxes) to be distributed to such ineligible ADS Record Date Holders in amounts equal to their pro
rata share by means of a check mailed to the last known address of each such ADS Record Date Holder. 
 d. The Agent will effect transfers and
assignments of ADS Subscription Forms as directed by the ADS Rights Holders thereof, and will send to each transferee or assignee of ADS Subscription Forms (or portions thereof), by first class mail to a Domestic Holder, and by airmail to an
Overseas Holder (without registration or insurance), upon cancellation of such ADS Subscription Forms, a newly issued ADS Subscription Form together with the other documents described in clause (b)(i) above. 

e. The Company authorizes the Agent to waive proof of authority to sign (including the right to waive signatures of co-fiduciaries and proof of
appointment or authority of any fiduciary or other person acting in a representative capacity) in connection with the transfer or assignment of ADS Subscription Forms (or portions thereof) representing ADS Rights; provided, however,
that the signature to the relevant instrument of transfer or assignment is guaranteed by an eligible guarantor institution which is a member of a Medallion Signature Guarantee Program. 
 f. In the event that, prior to the Expiration Date, any person notifies the Agent that the ADS Subscription Form to which such person is entitled has not been delivered, or has been lost, stolen or
destroyed, the Agent will arrange for the issuance of a new ADS Subscription Form and the delivery of the other documents described in clause (b)(i) above to any person from whom it has received, prior to


  
 8 








 
the Expiration Date, a duly executed letter or other communication satisfactory to the Agent indicating the name and address of the registered ADS Rights Holder of the lost ADS Subscription Form,
the certificate number of such ADS Subscription Form, and the number of ADS Rights represented thereby, or has otherwise satisfied the Agent as to such failure of delivery, or lost, stolen or destroyed ADS Subscription Form in accordance with
procedures which are standard to the industry; provided, however, that such issuance may be delayed by the Agent, in its discretion, pending receipt of an indemnity from such person satisfactory to the Company and the Agent and
confirmation that such lost, stolen or destroyed ADS Subscription Form has not been exercised or transferred. Upon issuance of such new ADS Subscription Form, the Agent shall cancel all such ADS Subscription Forms which are claimed not delivered or
were lost, stolen or destroyed and shall record such cancellation in the register of ADS Rights to be maintained by the Agent. 
 g. An ADS
Rights Holder may place an order with the Agent to sell all or a portion of such ADS Rights Holder’s ADS Rights and, in such event, shall deliver its ADS Subscription Form(s) to the Agent. The Agent must receive such ADS Rights Holder’s
ADS Subscription Form(s) prior to 5:00 p.m. (New York City time) on March 13, 2013. In connection with any sale of ADS Rights, the Agent may charge a fee of up to US$0.10 per New ADS issued (equivalent to US$0.05 per ADS held). At least once
weekly during the period when the ADS Rights are traded on The New York Stock Exchange, the Agent will aggregate the ADS Rights delivered to it with instructions to sell and will arrange for their sale on the New York Stock Exchange through a broker
appointed by the Agent for such purpose. The Agent will not be liable to any ADS Rights Holder for its failure to obtain the best market price for any ADS Rights it sells at the request of an ADS Rights Holder. Each seller of ADS Rights through the
Agent will receive the net sale price for the ADS Rights sold, calculated on the basis of the weighted average of all sales of ADS Rights by the Agent during the ADS Rights trading period net of expenses, commissions and fees incurred in connection
with such sales. 
 h. If the Agent does not receive instructions to exercise ADS Rights prior to 2:15 p.m. (New York City time) on the
Expiration Date, those ADS Rights will be void and will have no further value. 
 i. The Company and the Agent agree that the Depositary shall
be authorized to charge exercising ADS Rights Holders an ADS issuance fee of US$0.10 per New ADS issued (equivalent to US$0.05 per ADS held) in connection with the ADS Rights Offer in accordance with the Deposit Agreement. The Company and the Agent
agree that the Agent shall be authorized to charge ADS Rights Holders certain fees as set forth on Exhibit B attached hereto.

obtain all necessary proof of authority to sign in connection with the subscriptions for New ADSs, provided, however, that in the event that such proof of authority has not been received on or prior to the Expiration Date, the Agent

d. The Agent shall instruct the Custodian to pay the U.S. dollar amount equal to the Balance Share Subscription Price in accordance with the subscription
procedures of the Share Rights Offer. 
  

	11.	Distribution of Excess Amount and Payment of USD Deficiency Amount. 

 a. If either (i) the Interim ADS Subscription Deposit Amount exceeds the U.S. dollar equivalent of the Interim Share Subscription Price based on the Interim Initial Conversion Exchange Rate, or
(ii) the Balance ADS Subscription Deposit Amount exceeds the U.S. dollar equivalent of the Balance Share Subscription Price based on the Balance Initial Conversion Exchange Rate, the Agent shall instruct the Custodian to transfer, promptly
following the expiration of the Interim Share Subscription Period, in the case of (i) above, or the Share Subscription Period, in the case of (ii) above, by electronic transfer of funds to an account designated by the Agent, the amount by
which the Interim ADS Subscription Deposit Amount or the Balance ADS Subscription Deposit Amount, as applicable, so exceeds the U.S. dollar equivalent of the Interim Share Subscription Amount or the Balance Share Subscription Amount, respectively
(the “Excess Amount”), in U.S. dollars. 
 b. If either (i) the Interim ADS Subscription Deposit Amount is less than the
U.S. dollar equivalent of the Interim Share Subscription Price based on the Interim Initial Conversion Exchange 

  
 12 









 
Rate, or (ii) the Balance ADS Subscription Deposit Amount is less than the U.S. dollar equivalent of the Balance Share Subscription Price based on the Balance Initial Conversion Exchange
Rate, the Company shall notify the Agent, through the Custodian, at or prior to 9:00 a.m. (New York City time) on the Business Day immediately preceding the expiration of the Interim Share Subscription Period, in the case of (i) above, or
promptly following the Share Subscription Period, in the case of (ii) above, of the additional U.S. dollar amount necessary to pay the Interim Share Subscription Price or the Balance Share Subscription Price in full, as applicable (the
“USD Deficiency Amount” and, to the extent any Excess Amount remains following the subtraction of the USD Deficiency Amount calculated after the Expiration Date, the “Final Excess Amount”). The Agent shall prior to
the delivery of the Share Rights in connection with the CP Exercise, in the case of (i) above, or promptly following the expiration of the Share Subscription Period, in the case of (ii) above, transfer, by electronic transfer of funds to
the Custodian Account, as applicable, an amount in U.S. dollars sufficient to cover the USD Deficiency Amount. 
 c. As
soon as practicable after the determination of the USD Deficiency Amount following the Expiration Date, the Agent shall notify each ADS Rights Holder exercising ADS Rights of its pro rata share of the USD Deficiency Amount. Each ADS Rights Holder
exercising ADS Rights shall promptly pay its pro rata share of the USD Deficiency Amount to the Agent. The Agent will not deliver New ADSs subscribed for by such ADS Rights Holder prior to the receipt by the Agent of such payment. If payment of the
applicable USD Deficiency Amount is not received from the ADS Rights Holder exercising ADS Rights by the Agent by the close of business on the tenth (10th) Business Day following the date of notice of such USD Deficiency Amount, the Agent shall sell all or a portion
of such New ADSs subscribed for by such ADS Rights Holder in a commercially reasonable manner, and in an amount sufficient to cover such USD Deficiency Amount and to cover any costs incurred in selling such New ADSs. In such event, the Agent will
then deliver the remaining New ADSs (if any) to such exercising ADS Rights Holder together with a check in the amount of the excess proceeds, if any, from such sale (after deduction of applicable Depositary fees of US$0.10 per New ADS sold
(equivalent to US$0.05 per ADS held), expenses and taxes). If, however, the amount of excess proceeds from such sale of New ADSs is less than US$5.00, the Agent will (after deductions of applicable Depositary fees of US$0.10 per New ADS sold
(equivalent to US$0.05 per ADS held), expenses, taxes and sales commissions) distribute such proceeds to the Company. The Agent will thereupon have the right to reimbursement by the Company with respect to any USD Deficiency Amount not collected as
provided above from any such exercising ADS Rights Holder after such sale of New ADSs and application of the proceeds thereof (less such costs) to any such USD Deficiency Amount owed by such exercising ADS Rights Holder to the Agent. 

d. The Agent shall only remit to each exercising ADS Rights Holder its pro rata share of the Final Excess Amount (after deduction of applicable expenses)
to the extent any such Final Excess Amount remains after the Expiration Date. 
  

	12.	Deposit of New Shares and Issuance of New ADSs. 

 a. The Company shall, as soon as practicable after the issuance of the New Shares represented by the New ADSs subscribed for pursuant to the ADS Rights Offer, cause to be deposited such New Shares in an
account maintained by the Custodian in the name of the Depositary or its designated nominee. 

  
 13 









 b. The Depositary shall as soon as practicable after the Company shall cause New Shares to be so deposited
pursuant to paragraph (a) of this Section 12, issue, in accordance with the terms of the Deposit Agreement, New ADSs subscribed for pursuant to the ADS Rights Offer and, subject to Section 11(c) hereof: (i) in the case of ADS
Rights exercised through DTC, make delivery thereof to the applicable DTC participants, and (ii) in the case of ADS Rights exercised by registered ADS Rights Holders, mail to each subscribing ADS Rights Holder, in the manner specified by such
subscribing ADS Rights Holder, an ADR representing the number of New ADSs for which such subscribing ADS Rights Holder has subscribed. Each ADR will be registered in the name specified by the subscribing ADS Rights Holder on its ADS Subscription
Form. 
 c. Any ADR requested to be mailed by the subscribing ADS Rights Holder therefor will be mailed by the Agent by first class mail, in
each case under its blanket surety bond and within the limits thereof, protecting the Agent and the Company from any loss or liability arising out of nonreceipt or nondelivery of any such ADR or the replacement thereof. 

 

	13.	Destruction of ADS Subscription Forms. 

 Promptly after the Expiration Date, the Agent shall cause any unused ADS Subscription Forms in its possession to be destroyed and all ADS Subscription Forms that were registered or assigned and all ADS
Subscription Forms that were exercised will be cancelled and destroyed. The Agent will provide to the Company a record of such ADS Subscription Forms that have been cancelled and destroyed upon the Company’s request. 

 

	14.	Taxes. 

 a. The Agent shall not be
required to mail to the recipients of ADS Rights any tax reports or to file any reports with the U.S. Internal Revenue Service (“IRS”) in respect of the ADS Rights distributed or exercised or the New ADSs delivered upon subscription
therefor under the ADS Rights Offer. 
 b. The Company will be fully responsible for preparing and timely filing all U.S. returns and
information statements, relating to the ADS Rights Offer, required to be filed pursuant to U.S. Treasury regulations promulgated under Internal Revenue Code section 6045B. 
 c. On or before January 31st of the year following the year of the sale of any ADS Rights (or fractional entitlements to ADS Rights) by the Agent, the Agent shall prepare and mail to each ADS Rights
Holder who has received from the Agent cash proceeds in accordance with the terms hereof, other than ADS Rights Holders who demonstrate their status as nonresident aliens (“Non-U.S. Holders”) or other exempt recipients, in
accordance with U.S. Treasury regulations, a Form 1099-B reporting the amount of cash proceeds. The Agent shall also prepare and timely file copies of such Forms 1099-B, electronically with the IRS, make all filings with the IRS, provide to
surrendering holders all necessary reports, and take any further actions to the extent related to the ADS Rights Offer and required by U.S. Treasury regulations promulgated under Internal Revenue Code sections 6042, 6043 and/or 6045 to be taken by
the Company or the Agent. The Agent shall not be required to mail to the recipients of New ADSs any tax reports or to file any reports with the IRS in respect of the ADS Rights exercised in the ADS Rights Offer except as specified above or as
required by U.S. Treasury Regulations applicable to the Agent. If the Agent has not received notice from the ADS Rights Holder its Taxpayer Identification Number (“TIN”), or if such TIN has not been certified as correct or such


  
 14 









 
holder otherwise fails to comply with applicable procedures necessary to show that such ADS Rights Holder is not subject to the back-up withholding tax provisions under the U.S. Treasury
regulations, the Agent shall deduct and withhold the applicable percentage of any cash payment, made to such ADS Rights Holder and remit such funds to the IRS in accordance with the Agent’s standard procedures. Should any issue arise regarding
U.S. federal income tax reporting or withholding, the Agent shall take such action as the Company instructs to the Agent in writing in light of the Agent’s obligations hereunder, subject to the advice of its counsel. The Agent will notify the
Company of any tax liability, including U.S. federal tax liability arising in connection with the ADS Rights Offer and will promptly deliver to the Company a copy of any notice or communication received from any tax authority, including the IRS,
related to the ADS Rights Offer or this Agreement. 
  

	15.	Instructions and Indemnification. 


a. The Agent will be entitled to rely upon any instructions or directions furnished to it in writing by any director or officer to the Company or any
attorney-in-fact for the Company appointed for this purpose pursuant to a power of attorney signed by any director or officer of the Company, and to apply to such individuals for advice or instructions in connection with its duties, and will be
entitled to treat as genuine, and as the document it purports to be, any letter or other document, furnished to it by such individuals. The Agent shall incur no liability or responsibility to the Company for any action taken in reliance on, and in
accordance with, any notice, resolution, waiver, consent, order, certificate, or other paper, document or instrument believed by it to be genuine and to have been signed, sent or represented by the proper party or parties. 

b. The Company will indemnify the Agent against, and defend and hold it harmless from, any and all liability and related expenses (including reasonable
fees and expenses of its counsel) incurred by the Agent, which may arise out of acts performed or omitted in connection with this Agreement, as the same may be amended, modified, or supplemented from time to time: (i) by the Agent, except to
the extent such liability or expense arises out if its own negligence or willful misconduct, or (ii) by the Company or any of its agents. 

c. The Agent will indemnify the Company against, and defend and hold it harmless from, any and all liability and related expenses (including reasonable
fees and expenses of its counsel) incurred by the Company, arising out of negligence or willful misconduct of the Agent, the Custodian or any of their respective employees, officers, directors or agents. 

d. If any action or claim shall be brought or threatened to be brought against any party in respect of which indemnity may be sought pursuant to this
Section 15, such indemnified party shall, as soon as practicable (or, in the case of any action or claim which is threatened to be brought, as soon as practicable after such party actually becomes aware of the same) notify the party against
whom indemnity may be sought in writing of such action or claim, and in such circumstances, and also in the event of any action or claim being brought or threatened to be brought against any of the parties thereto, the other party thereto shall
provide to the party against whom such action or claim is brought or threatened to be brought, such information and assistance as such party shall reasonably request, subject always to the provisions of indemnity contained in this Section 15.
Each party shall to the extent reasonable and practicable in all circumstances consult with the other party as and when reasonably requested by such party in respect of any action or claim referred to in this Section 15. 

e. The obligation set forth in this Section 15 shall survive notwithstanding the termination of this Agreement and the succession or substitution of
any indemnified person.

 This Agreement will be governed by, and construed and interpreted in accordance with, the laws of the State of New York. The parties agree that the federal and state courts located in the City of New

accept for and on its behalf and on behalf of its properties, assets and revenues, service by mail of any and all legal process, summons, notices and documents that may be served in any suit, action or proceeding brought against the Company in any
court as described in the preceding sentence. If for any reason the Company’s authorized agent shall cease to be available to act as such, the Company agrees to designate a new authorized agent in the United States for receiving and accepting
service of all legal process on the terms and for the purposes of this Section 18 reasonably satisfactory to the Agent. The Company further hereby irrevocably consents and agrees to any and all legal process, summons, notices and documents that
may be served in any suit, action or proceeding against it under the terms hereof, by service by mail of a copy thereof upon its authorized agent (whether or not the appointment of its authorized agent shall for any reason prove to be ineffective or
its authorized agent shall fail to accept or acknowledge such service), with a copy mailed to the Company by registered or certified air mail, postage prepaid, to its address provided herein. The Company agrees that the failure of its authorized
agent to give any notice of such service to it shall not impair or affect in any way the validity of such service or any judgment rendered in any action or proceeding based thereon. The Company irrevocably and unconditionally waives, to the fullest
extent permitted by law, any objection that it may not now or hereafter have to the laying of venue of any actions, suits or proceedings brought in any court as provided herein, and hereby further irrevocably and unconditionally waives and agrees
not to plead or claim in any such court that any such action, suit or proceeding brought in any such court has been brought in an inconvenient forum. The provisions of this Section 18 shall survive notwithstanding the termination of this
Agreement.
