	3.	ADS Offer 

  

	 	a.	 Pursuant to the Deposit Agreement and this Agreement, the Company will cause the Agent to distribute to registered holders of record of ADSs one (1) ADS Right for
every ADS held as of the Record Date. No fractional ADS Rights will be issued and fractions of New ADSs arising from the exercise of ADS Rights will 



  

 5 









	 	 
be rounded down to the nearest whole number with no compensation for such fraction. One (1) ADS Right will entitle the holder thereof to subscribe for [one
(1) New ADS] at the ADS Subscription Amount ADS Rights will be evidenced by ADS Rights Certificates. The ADS Offer will be made to holders of ADSs of record on the Record Date by means of, inter alia, the Prospectus to be mailed or
distributed to such holders as described in Section [3] of Schedule [I] attached hereto. The ADS Subscription Period will expire on the Expiration Date. After the Expiration Date, ADS Rights (and the ADS Rights Certificates evidencing

Primary ADS Rights and Primary Share Rights subject to the terms and conditions of the Prospectus. If the aggregate number of additional New Shares available for subscription pursuant to the Oversubscription ADS Rights and Oversubscription Share
Rights equals or exceeds the aggregate number of additional New Shares (including New Shares in the form of New ADSs) subscribed for, the Company will allocate to each holder of ADS Rights who has exercised his/her Oversubscription ADS Rights the
number of additional New Shares in the form of New ADSs subscribed. In the case of oversubscription pursuant to the exercise of Oversubscription Share Rights and Oversubscription ADS Rights, the Company will allocate additional New Shares (the Agent
shall subsequently applying such allocation to the New ADSs) in accordance with the terms and subject to the limitations and conditions set forth in the Prospectus. Holders of ADS Rights must deliver to the Agent the U.S. Dollar Payment for the
additional New ADSs applied for pursuant to the exercise of the Oversubscription ADS Rights at the same time that holders exercise their Primary ADS Rights and deliver the U.S. Dollar Payment for the New ADSs to be issued pursuant to the exercise of
Primary ADS Rights. If holders who have applied to subscribe for additional New ADSs are allocated a smaller number of additional New ADSs than they applied for pursuant to the exercise of Oversubscription ADS Rights, the Agent will as soon as
practicable refund to the applicable holders any excess paid net of amounts otherwise owed to the Depositary in connection with the exercise of Primary ADS Rights.

matter and which is no longer subject to review or appeal, or (b) the dispute has been settled by a written document and executed by the Company and, if applicable, binding upon all holders of ADSs subscribing for New ADSs interested in the matter.

  

	 	c.	Judgments; Court Orders.

delivery of any 

  

 11 








 
such Property shall be stayed or enjoined by any court order, or if any order, judgement or decree shall be made or entered by any court affecting such
Property or any part thereof, then and in any such event the Agent shall be authorized, in its sole discretion, to rely upon and comply with any such order, judgement, or decree which the Agent has been advised in writing by legal counsel of its own
choosing (and reasonably satisfactory to the Company) is binding upon it. If the Agent complies with any such order, judgement, or decree, it shall not be liable to any person or entity by reason of such compliance even though such order, judgement,
or decree may be subsequently reversed, modified, annulled, set aside, or vacated, unless the Agent has acted negligently or in bad faith. 
  

	 	d.	Defending Litigation. 

  
 The Agent agrees to notify the Company within three (3) Business Days in writing of the commencement of any action against the Agent or any Indemnitee for
which indemnification is being or may be sought hereunder if the Company is not a party to such action. Unless the Agent has acted negligently or in bad faith, the failure by the Agent to so notify the Company will not (i) relieve the Company from
its indemnification obligations hereunder unless and to the extent the Company did not otherwise learn of such action and such failure results in the forfeiture by the Company of substantial rights and defenses, and (ii) in any event relieve the
Company from any other obligations to the Agent or any other Indemnitee hereunder. 
  
 The Company shall (except as noted below) be entitled to assume the defense of any third-party claim, legal action or proceeding against the Agent and/or any Indemnitee for which indemnification is or may be sought
hereunder and agrees to pay the fees and expenses of the counsel chosen by it. All reasonable costs and expenses incurred by the Agent in connection with any such third-party claim, action or proceeding shall be covered by the indemnification
obligations of the Company under the terms of this Agreement. 
  
 Notwithstanding the Company’s election to assume the defense of such claim, action or proceeding, the Agent shall have the right to employ separate counsel (reasonably acceptable to the Company) and to participate in the defense of
such claim, action or proceeding, and the Company shall bear the reasonable fees, costs and expenses of such separate counsel if (i) the use of counsel chosen by the Company to represent the Indemnitees would present such counsel with a conflict of
interest; (ii) the actual or potential defendants in, or targets of, any such claim, action or proceeding include both the Company and the Indemnitees, and the Agent shall have reasonably concluded that there may be legal defenses available to the
Indemnitees which are different from or additional to those available to the Company (in which case the Company shall not have the right to assume the defense of such claim, action, or proceeding on behalf of the Indemnitees); (iii) the Company
shall not have employed counsel to represent the Indemnitees within a reasonable time after notice of the institution of such action; or (iv) the 

  

 12 








 
Company shall authorize the Agent to employ separate counsel (reasonably acceptable to the Company) at the Company’s expense, unless the Agent has acted
negligently or in bad faith. The Company shall not be liable for the fees and expenses of more than one separate counsel (plus one local counsel in each applicable jurisdiction) under the terms hereof in any single claim, action or proceeding for
all Indemnitees unless the Company consents or unless a bona fide conflict of interest requires separate counsel for particular Indemnitees. 
  
 No settlement shall be reached in any such claim by any Indemnitee, action or proceeding without the consent of the Company (which consent shall not be
unreasonably withheld). 
  
 The provisions of this Section
[12] shall survive the termination of this Agreement. 
  

	13.	Amendments and Assignments 

  

	 	a.	The terms of this Agreement may be waived, amended or supplemented only by agreement in writing duly executed by all parties hereto. The rights and remedies conferred upon the
parties hereto shall be cumulative and the exercise or waiver of any such right or remedy shall not preclude or inhibit the exercise of any additional rights or remedies, nor the subsequent exercise of such right or remedy. 


 

	 	b.	None of the rights and obligations of the parties under this Agreement may be assigned except (i) upon receipt of prior written consent of the other parties to this Agreement or
(ii) as otherwise specifically permitted by Section [3] hereof. Any assignment or delegation in violation of this Section [13(b)] shall be null and void.

 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 York, State of New York, shall have jurisdiction to hear and determine any suits, actions or proceedings and to settle any disputes between the parties relating to this Agreement and for such
purpose each of the parties irrevocably submits to the jurisdiction of such courts. The Company hereby designates, appoints and empowers [AGENT NAME & ADDRESS], as its authorized agent to receive and 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

terms and for the purposes of this Section [14] reasonably satisfactory to the Agent. 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 judgement rendered in any action or proceeding based thereon. The Company irrevocably and unconditionally waives, to the 

  

 13 








 
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 [14] shall survive notwithstanding the termination of this Agreement. 
  

	15.	Partial Invalidity 

  
 In the event that any provision of this Agreement or the application thereof to any person or circumstances shall be determined by a court of proper
jurisdiction to be invalid or unenforceable to any extent, the remaining provisions of this Agreement, and the application of such provisions to persons or circumstances other than those as to which they are held invalid or unenforceable, shall be
unaffected thereby and such provisions shall be valid and enforceable to the fullest extent permitted by law in such jurisdiction so long as the fundamental relationships among the parties hereunder are not altered.

disclose such transactions and/or business to the Company, or (b) account for any profit made or payment received in, or as a part of, such transactions and/or business, provided, however, that any such action does not prejudice or interfere with
the due performance of the Agent’s obligations set forth hereunder. 

  

	 	b.	Nothing in this Agreement is intended, nor shall anything contained in this Agreement be deemed, to constitute (i) a waiver of any right under, or an amendment of, any term of any
other agreement between the Company and the Agent or any other member of Citigroup, or any instrument from the Company to the Agent or any other member of Citigroup, unless such waiver or amendment is specifically acknowledged in writing herein.


  

	 	c.	Nothing in this Agreement is intended to benefit any persons not specifically identified herein. Nothing herein shall be deemed to (i) give rise to a partnership or joint venture or

regulation of the United States, Portugal or any other country, or of any other governmental authority or regulatory authority or stock exchange, or on account of the possible criminal or civil penalties or restraint. In no event shall the Agent be

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 Rights Certificates were prepared. 

  

	 	b.	The Agent will cause to appear on each ADS Rights Certificate (i) the name of the holder of the ADS Rights to whom such ADS Rights Certificate is issued, (ii) the number of ADS
Rights to which such holder is entitled, and (iii) the certificate number of such ADS Rights Certificate. 

  

	 	c.	The Company authorizes the Agent, in connection with the initial issuance of ADS Rights Certificates or the subsequent issuance of any ADS Rights Certificate, as a result of any
transfer or assignment of all or a portion thereof, to sign ADS Rights Certificates by either the manual or the facsimile signature of a duly authorized officer of the Agent. Until the Agent has signed an ADS Rights Certificate, such ADS Rights
Certificate will not be valid or obligatory for any purpose. 

  

	3.	Issuance, Transfer, Sale and Exercise of ADS Rights 

  

	 	a.	On or prior to the date hereof, (i) the Company will deliver or cause to be delivered to the Agent sufficient copies of the Prospectus, (ii) Cleary, Gottlieb, Steen & Hamilton,
U.S. counsel for the Company, will deliver to the Agent two (2) original copies of a reliance letter addressed to the Agent to the effect that the Agent may rely on its legal opinion addressed to the joint global coordinators of the Offering

	 	b.	 (i) As soon as possible following the Record Date (after receipt of the items listed in Section [3(a)]), the Agent will send under its blanket surety bond:
(x) by first class mail, to each holder of ADSs having an address of record within the United States (each a “Domestic Holder”) on the Record Date: (A) an ADS Rights Certificate evidencing the ADS Rights to which such holder is
entitled pursuant to the ADS Offer, including an Instructions Booklet (as hereinafter 



  

 I-2 









	 	 
defined) relating to, inter alia, the exercise and transfer of the ADS Rights Certificate; and (B) a copy of the Prospectus; and (y) by air mail
(without registration or insurance) to each holder of ADSs having an address outside of the United States, of record (each an “Overseas Holder”) on the Record Date, the documents described in clause (x) above, unless otherwise
directed in writing to the Agent by the Company. 


  
 (ii) As soon as possible following the Record Date (after the Agent’s receipt of the items listed in Section [3(a)]), the Agent will (x) cause the Information Agent to distribute to DTC participants who hold ADSs as of the
Record Date sufficient copies (in the amounts requested by such DTC participants) of the following: (A) the Prospectus; (B) a broker letter substantially in the form set forth in Schedule [VI] attached hereto (the “Broker
Letter”); (C) a client letter substantially in the form set forth in Schedule [VII] attached hereto (the “Client Letter”); and (D) an instruction booklet substantially in the form set forth in Schedule [VIII]

	 	c.	In the event that any ADS Rights Certificate is returned to the Agent for any reason and proper delivery thereof cannot be effected on or prior to [DATE], 2004, the ADS
Rights represented by such ADS Rights Certificate 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 Rights Certificate that cannot be delivered. The
Agent shall cause the ADS Rights evidenced by ADS Rights Certificates not mailed to registered holders in accordance with Section [3(b)] hereof, to be sold and the aggregate net proceeds of the sale of all such ADS Rights (after subtraction
of applicable fees of up to US$[        ] per ADS Right sold, expenses and applicable taxes) to be distributed to such ineligible holders of ADSs in amounts equal to their pro rata share by means of a check mailed to
the last known address of each such holder. 

  

	 	d.	The Agent will effect transfers and assignments of ADS Rights Certificates (or portions thereof) as directed by the holders thereof, and will send to each transferee or assignee of
ADS Rights Certificates (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 Rights Certificates, a newly issued ADS Rights
Certificate 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 Rights Certificates (or portions thereof) evidencing ADS Rights; provided, however, that the signature to the relevant
instrument of transfer or assignment is guaranteed by an eligible 

  

 I-3 








 
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 Rights Certificate to which such person is entitled has not been delivered, or has been
lost, stolen or destroyed, the Agent will arrange for the delivery of a new ADS Rights Certificate and the delivery of the other documents described in clause (b)(i) above to any person from whom it has received, prior to the Expiration Date, a duly
executed letter or other communication satisfactory to the Agent indicating the name and address of the registered holder of the lost ADS Rights Certificate, the number of such ADS Rights Certificate, and the number of ADS Rights evidenced thereby,
or has otherwise satisfied the Agent as to such failure of delivery, or lost, stolen or destroyed ADS Rights Certificate 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 Rights Certificate has not been exercised or transferred.
Upon issuance of such new ADS Rights Certificate, the Agent shall cancel all such ADS Rights Certificates 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.	[Reserved] 

  

	 	h.	A holder of ADS Rights may request the exchange of ADS Rights for Share Rights. The Agent may issue Primary ADS Rights and Oversubscription ADS Rights in exchange for Share Rights
upon the due deposit of Share Rights. In connection with the exchange of Share Rights for ADS Rights or ADS Rights for Share Rights (i) the Agent will accept Share Rights deposited with its Custodian (as defined below) and will cause to be prepared
and issued in accordance with Section [2] and [3] hereof, ADS Rights Certificates evidencing the ADS Rights representing the Share Rights being deposited, in accordance with the instructions of, and for the benefit of, the depositing
holder, and (ii) the Agent will accept ADS Rights deposited with it and will cause such ADS Rights to be cancelled against the delivery of the underlying Share Rights in accordance with the instructions of, and for the benefit of, the depositing
holder. In connection with any issuance or cancellation of ADS Rights, the Depositary may, in its own discretion, charge a fee not exceeding US$[        ] per ADS Right issued or cancelled. 

  

	 	i.	If the Agent does not receive instructions to exercise, transfer or exchange any ADS Rights prior to 5:00 p.m. (New York City time) on [DATE], 2004, those ADS Rights will be
void and will have no further value. 

  

 I-4 









	 	j.	The Company hereby instructs the Agent, and the Agent hereby agrees, to treat, for purposes of U.S. tax reporting, the distribution of ADS Rights to holders of ADSs as a
“non-taxable stock dividend” under United States federal income tax law. 

  

	 	k.	The Company and the Agent agree that no fee shall be assessed to holders in connection with (i) the initial distribution of ADS Rights to registered holders of ADSs as of the Record
Date, or (ii) the exercise of the ADS Rights.

	 	a.	The Company hereby authorizes and directs the Agent to accept subscriptions for New ADSs on behalf of the Company upon the proper completion and execution of an ADS Rights

reasonable discretion, any improperly completed or unexecuted ADS Rights Certificate. 

  

	 	b.	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 any subscription with respect to which: 

  

	 	(i)	the surrendered ADS Rights Certificate is registered in the name of one or more individuals or an executor, administrator, trustee, custodian for a minor or other fiduciary and has
been executed by such registered holder or holders, provided that the New ADSs subscribed for are to be issued in the name of such registered holder or holders; 

  

	 	(ii)	the surrendered ADS Rights Certificate is registered in the name of a corporation and has been executed by an officer of such corporation, provided that the New ADSs subscribed for
are to be issued in the name of such corporation; 

  

	 	(iii)	the surrendered ADS Rights Certificate has been executed by a bank, trust company or broker as agent for the registered holder thereof, provided that the New ADSs subscribed for are
to be issued in the name of such registered holder; and 

  

	 	(iv)	the surrendered ADS Rights Certificate is registered in the name of a decedent and has been executed by a person who purports to act as the executor or administrator of such
decedent’s estate, provided that (A) such subscription is for not more than New ADSs, (B) the New ADSs 

  

 I-5 








 
are to be issued in the name of such person as executor or administrator of such decedent’s estate, (C) the check tendered in payment of such
subscription is drawn for the proper amount and to the order of the Agent, and is otherwise in order, and (D) there is no evidence indicating that such person is not the duly authorized representative which such person purports to be. 
  
 In all cases other than those described in clauses (i) through (iv) above,
the Agent will 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 shall obtain advice from the Company as to whether any such subscriptions may be accepted. 
  

	 	c.	The Company authorizes the Agent to accept customary letters of indemnification from commercial banks, trust companies or eligible guarantor institutions that are members of a
Medallion Signature Guarantee Program with respect to nonconforming aspects of documents delivered in connection with subscriptions for New ADSs.

made upon exercise of Primary ADS Rights and Oversubscription ADS Rights. 

  

	5.	Reports by the Agent

	6.	ADS Subscription Amount 

  

	 	a.	Primary ADS Rights - At or prior to 5:00 p.m. (New York City time), on or about [DATE], 2004, the Agent shall with respect to Primary ADS Rights validly exercised (i)
determine (A) the aggregate ADS Subscription Amount payable to the Company in respect of the total number of New ADSs subscribed for during the ADS Subscription Period upon exercise of the Primary ADS Rights, (B) the aggregate amount of U.S. Dollar
Payments received by the Agent and deposited in the NY Account in respect of such subscriptions, and (C) if the aggregate U.S. Dollar Payments received by the Agent in respect of such subscriptions shall be less than such aggregate ADS Subscription

for by such holder prior to the receipt by the Agent of such payment. If payment of the amount of any deficiency is not received from a subscriber by the Agent by [DATE], 2004, the Agent shall sell all or a portion of such New ADSs subscribed
for by such subscriber in a commercially reasonable manner, and in an amount sufficient to cover such Deficiency and to cover any costs incurred in selling such New ADSs. In such event, the Agent will then deliver the remaining New ADSs to such
subscriber together with a check in the amount of the excess proceeds, if any, from such sale (after deduction of all applicable fees, expenses and taxes). The Agent will thereupon have the right to reimbursement by the Company with respect to the
amount of any Deficiency not collected as provided above from any such holder after such sale of New ADSs and application of the proceeds thereof (less such costs) to any such amount owed by such holder to the Agent. If the aggregate U.S. Dollar
Payments received by the Agent in respect of such subscription shall be greater than such aggregate ADS Subscription Amount for the total number of New ADSs subscribed for pursuant to the exercise of Primary ADS Rights, the Agent shall, as promptly
as practicable, remit any excess funds (after deduction of applicable expenses) to the applicable exercising holders of Primary ADS Rights.

Subscription Period upon exercise of Oversubscription ADS Rights, (B) the aggregate amount of U.S. Dollar Payments received by the Agent and deposited in the NY Account in respect of such subscriptions, and (C) if the aggregate U.S. Dollar Payments
received by the Agent in respect of such subscriptions shall be less than such aggregate ADS Subscription Amount for the total number of additional New ADSs subscribed for pursuant to the exercise of Oversubscription 



  

 I-7 









	 	 
ADS Rights, determine the amount of additional U.S. dollars necessary to pay such aggregate ADS Subscription Amount in full (the “Additional
Deficiency”), and (ii) deliver into the NY Account immediately available funds in an amount equal to such Additional Deficiency. Each exercising holder of the Oversubscription ADS Rights shall promptly pay its pro rata share of the amount
of such Additional Deficiency to the Agent. The Agent will not deliver additional New ADSs subscribed for by such holder prior to the receipt by the Agent of such payment. If payment of the amount of any deficiency is not received from a subscriber
by the Agent by [DATE], 2004, the Agent shall sell all or a portion of such additional New ADSs subscribed for by such subscriber in a commercially reasonable manner, and in an amount sufficient to cover such Additional Deficiency and to
cover any costs incurred in selling such additional New ADSs. In such event, the Agent will then deliver the remaining additional New ADSs to such subscriber together with a check in the amount of the excess proceeds, if any, from such sale (after
deduction of all applicable fees, expenses and taxes). The Agent will thereupon have the right to reimbursement by the Company with respect to the amount of any Additional Deficiency not collected as provided above from any such holder after such
sale of additional New ADSs and application of the proceeds thereof (less such costs) to any such amount owed by such holder to the Agent. If the aggregate U.S. Dollar Payments received by the Agent in respect of such subscription shall be greater
than such aggregate ADS Subscription Amount for the total number of additional New ADSs subscribed for pursuant to the exercise of Oversubscription ADS Rights, the Agent shall, as promptly as practicable, remit any excess funds (after deduction of
applicable expenses) to the applicable exercising holders of Oversubscription ADS Rights.

respect of the Oversubscription ADS Rights validly exercised and shall, as promptly as practicable on the Allocation Date or thereafter, pay to the Company, by electronic transfer of funds to an account designated by the Company, an amount, in Euro,
