Securities are deemed to be deposited to cover Transactions when they are: (i) for such purpose kept in the Clearinghouse Deposit Account until the deadline which the Clearinghouse has set for final processing of the Settlement of the corresponding Delivery obligation; or (ii) to be received for the Settlement of an acquisition in a public offering or a Central Bank Credit Facility operation under article 74. Sole paragraph. The making of a deposit to cover Transactions and the Acceptance of a Transaction for which Securities have been deposited under this article may alter the Participants limits pursuant to the provisions set forth in the Clearinghouse Risk Management System Manual. While kept as a deposit pursuant to the provisions set forth in item (i) of the previous article, Securities shall, prorated to the quantities deposited, meet the Delivery obligations arising from Transactions accepted from the Direct Participant to the Clearinghouse and from the Securities Trading Participant to the Clearing Member. Paragraph 1. A Delivery obligation which is met pursuant to this article, while remaining as such, is not subject to Netting as referred to in Chapter X, and is terminated upon Gross Settlement. Paragraph 2. The Clearinghouse may, as provided for in its Risk Management System and Procedures Manuals, establish a priority order for obligations to be met as set forth in this article. Paragraph 3. Final processing of the Settlement of the Delivery obligation as set forth in this article takes place at such time as the Clearinghouse shall set which is comprised between the closing time for the Acceptance of Transactions with Settlement scheduled for that very date and the Settlement Window on the same date. Securities deposited pursuant to the provisions set forth in item (i) of article 50 may be withdrawn by the Participants or earmarked for other purposes, at their request, provided the requirements pertaining to risk management and the established operating procedures are met. CHAPTER IX TRANSACTIONS SECTION I GENERAL PROVISIONS Article 53. The following types of Securities Transactions, which are entered into the Clearinghouse systems pursuant to the terms and conditions set forth in the Rulebook, may be subject to Acceptance, Netting and Settlement by the Clearinghouse: 21

(i) same day or forward Purchase and Sale Transactions; (ii) Repo transactions; (iii) Loans; and (iv) Interchanges. Paragraph 1. The Settlement date of obligations pertaining to accepted Transactions cannot exceed the maturity date of any underlying Security. Paragraph 2. Obligations in funds derived from amounts paid by issuers as interest, amortization and redemption income from Securities traded in the Transactions may be settled through the Clearinghouse in the events referred to in this Rulebook or defined by BM&F in a Circular Letter. Paragraph 3. In the event of an early redemption, by the issuer, of the total number of any given Security underlying Transactions with Settlement scheduled for a date later than the redemption date, or any other occurrence which may, at the discretion of the Clearinghouse, result in extraordinary difficulties or in the impossibility of the Participants or the Clearinghouse to meet future Delivery obligations of the Security, the Clearinghouse may, as regulated in the Procedures Manual or in Circular Letters and Communications from BM&F, provide for the adoption of exceptional measures and criteria, such as an earlier date for Settlement or for maturity of Transactions, as well as the cancellation of Transactions and of other obligations deriving therefrom, such as those involving intermediate interest payments. SECTION II ENTERING TRANSACTIONS INTO THE CLEARINGHOUSE SYSTEMS Article 54. Transactions subject to Acceptance by the Clearinghouse are entered into its systems through Trading or Registration Systems in observance of the rules applicable to each case. Sole paragraph. The Clearinghouse may set rules, procedures and specific control mechanisms to be observed by the Trading or Registration Systems, as well as requiring the Pre-Registration of certain Transactions. SECTION III ACCEPTANCE OF TRANSACTIONS Article 55. The Acceptance of any Transaction is conditional upon: (i) observance of the involved Participants limits in accordance with the provisions set forth in the Clearinghouse Risk Management System Manual; and (ii) adoption of all established operating procedures and conformity to all controls established in the Trading or Registration System used. Sole paragraph. Without prejudice to such procedures as adopted in exceptional situations, the analysis under item (i) of this article is conducted upon entry of the Transaction into the Clearinghouse. 22

Article 56. The Clearinghouse takes the position of central counterparty for Settlement purposes of accepted Transactions, ensuring the settlement thereof pursuant to current legislation and the rules, procedures and criteria set forth in this Rulebook. Paragraph 1. The Acceptance of Repo Transactions comprises the Acceptance of both the purchase and sale Transaction and the Transaction pertaining to the corresponding resale and repurchase commitment. Paragraph 2. The Acceptance of Transactions which are subject to Pre-Registration is conditional upon all necessary requirements being met as established in this Rulebook and other applicable rules. Paragraph 3. The cancellation of any accepted Transaction, upon request by the involved Participants, before the Settlement of any of the corresponding obligations is subject to the analysis and other provisions concerning risk set forth in the Clearinghouse Risk Management System Manual. When a cancellation is complied with by the Clearinghouse, it may change the operational limit of the involved Participants, including the Clearing Member of the Securities Trading Participant that has required this cancellation, in addition to causing the Clearinghouse to be no longer characterized as the central counterparty for Settlement purposes of any corresponding obligations. SECTION IV SPECIFIC TRANSACTIONS SUBSECTION I PURCHASE AND SALE TRANSACTIONS Article 57. The Settlement of Securities Purchase and Sale Transactions may be: (i) same day, when their Settlement date is the same as their Acceptance date; or (ii) forward, when their Settlement date is on a date which is subsequent to their Acceptance date and up to the business day preceding the redemption date of the Security, observing the maximum tenor set by the Clearinghouse. Paragraph 1. The amounts paid by the issuer as interest or amortization income from Securities traded in accepted forward Purchase and Sale Transactions, from the business day following the Acceptance date of the Transaction to, and including, the Settlement date thereof, updated according to the criteria published by BM&F, make up the Final Buyer s rights and the Final Seller s duties in funds on the Settlement date of the Transaction. Paragraph 2. The updating referred to in the previous paragraph is calculated from the date of payment by the issuer until the Settlement date of the Transaction. Paragraph 3. BM&F may establish an operating mode in which amounts paid as interest or amortization income from Securities traded in accepted forward Purchase and Sale Transactions, from the business day following the Acceptance date of the Transaction to the Settlement date thereof, do not make up the Participants rights and duties in funds scheduled for the Settlement date of the Transaction. 23

Article 58. Forward Purchase and Sale Transactions on a when-issued basis may be based on a Security offered in a public offering, irrespective of any Securities of the same kind (type, issuer and maturity) outstanding in the market, in which event the Settlement thereof must coincide with the date set for the Settlement of the relevant public offering. Paragraph 1. Paragraph 2. Paragraph 3. The Forward Purchase and Sale Transactions referred to in this article may be subject to Pre-Registration from the moment the public offering of the relevant Securities is officially announced by the issuer, with their Acceptance and Registration being subject to compliance with the conditions to be published by BM&F and established by taking into consideration the National Monetary Council s and the Central Bank of Brazil s own regulations for forward purchase and sale commitments based on the Securities referred to in this article. Any obligations arising from the Acceptance of forward Purchase and Sale Transactions referred to in this article shall prevail even if the Participant appearing as seller of the Security underlying the Transactions is unable to acquire said Security in the public offering, in which event it must resort to other sources to obtain it. The Clearinghouse Risk Management System Manual provides a specific treatment for the forward Purchase and Sale Transactions referred to in this article, to be applied as long as their Acceptance is not made effective. SUBSECTION II REPO TRANSACTIONS Article 59. A Repo Transaction is the purchase or sale of a Security, called Repo Collateral, accumulated with a commitment consisting of the resale or repurchase of the same Security, where the Settlement of obligations arising from the purchase and sale Transaction takes place: (i) on the same date as the Acceptance date of the Transaction, with the obligations arising from the resale and repurchase Transaction having a future Settlement date; or (ii) on a future date after the Acceptance date of the Transaction, with the obligations of the resale and repurchase Transaction having a Settlement date subsequent to that of the obligations arising from the purchase and sale Transaction. Paragraph 1. In the event under item (i), it is admissible for the Settlement date of the resale and repurchase Transaction to be the same date as the Settlement date of the purchase and sale Transaction, in the case of any Repo Transactions referred to in article 4, where the purchase and sale Transaction has its Settlement through the Clearinghouse or SELIC and the resale and repurchase commitments consist of a Transaction for which the obligations shall be settled, respectively, through SELIC or the Clearinghouse. Paragraph 2. The amounts paid by the issuer as interest or amortization income from Securities traded in accepted Repo Transactions, from the business day following the Settlement date of the purchase and 24
