(I) General Provisions

1.1. This Administrative Guideline aims to ensure transparency in the procedures and flows of financial transfers, carried out by CAMARB, to Arbitrators, Emergency Arbitrators, Mediators, Members of CPRDs, Members of Challenge Committees and Experts, who act in procedures administered by the Chamber.

1.2. The time frames for payment refer to the moment in which payment of a certain portion of the fees is due to the professional. The pertinent analyses will be made by the General Secretariat of CAMARB in accordance with the CAMARB Rules and Fee Schedules applicable to the specific case, as well as the rules contained in the Arbitration Term (in the case of ordinary arbitration), Commencement Term (in the case of expedited arbitration), Mediation Contract (in the case of mediation), Term of Establishment of the Dispute Prevention and Resolution Committee (in the case of a dispute board), as well as the proposal for expert fees approved by the Arbitration Court.

1.2.1. In the case of ordinary or expedited arbitration, if there is no change to the Arbitration Agreement signed by the Parties, the Arbitration Term or the Commencement Term, the general rule adopted by CAMARB for the time frames for the release of arbitration fees will prevail, which is:

(i) 30% (thirty percent) after the execution of the Arbitration Agreement with the signature of all Parties of the aforementioned document;
(ii) 30% (thirty percent) after the conclusion of the evidentiary investigation, indicated by the Arbitral Tribunal; and
(iii) 40% (forty percent) after the arbitration award has been filed by the Arbitration Court at the CAMARB Secretariat; in the event of a partial award, 20% (twenty percent) of the balance due may be released.

1.2.1.1. In the event of replacement of the Arbitrator during the arbitration proceedings, if there is no agreement otherwise between the Parties and the Arbitral Tribunal, payment of the fees of said Arbitrator will be made in accordance with the parameters indicated above, with the professional being remunerated up to the last time frame in which he/she acted in the proceedings.

1.2.2. The Emergency Arbitrator's fees will be paid in a single installment, after the Emergency Procedure Decision has been filed by the Emergency Arbitrator with the CAMARB Secretariat.

1.2.3. As for the Mediator's fees, the criteria defined in the Mediation Rules[2] and in the CAMARB Schedule of Costss[3], as well as in the Mediation Contract, will be observed. Unless otherwise agreed, the fees will always be paid to the professional upon submission of the hours report totaling 5 (five) hours, when the estimated value of the dispute is up to R$200.000,00 (two hundred thousand reais), or 10 (ten) hours, when the estimated value of the dispute is greater than R$200.000,00 (two hundred thousand reais).

1.2.3.1. In order to prove the hours spent by the mediator, a time report must be presented, and the professional must indicate when he/she is close to completing the guaranteed hours, so that the CAMARB Secretariat can collect a new advance payment from the Parties and initiate the payment procedures, as provided for in this Guideline.

1.2.4. The fees of Members of CPRD Committees will follow the criteria defined in the Rules[4] and in the CAMARB Costs Schedule[5], unless otherwise agreed between the Parties and the Member(s), and are composed of daily fees and monthly fees, paid by the 10th of each month following the month in which the fee is charged, upon submission of the collection document by the said Member(s).

1.2.5. The fees of the Members of the Challenge Committees will be paid, in a single installment, after the decision to challenge has been filed with the CAMARB Secretariat.

1.2.5.1. If the estimated value of the dispute, which is the subject of the challenge assessed by the Committee, exceeds R$10.000.001,00 (ten million and one reais)[6], the report of the hours spent by the Members of the aforementioned Committee must be submitted together with the decision to challenge. The report will be checked by the CAMARB Secretariat so that it can take the necessary measures to collect the funds needed to pay the hourly fees, with a minimum of 10 (ten) hours and a maximum of 30 (thirty) hours per Member of the Committee.

1.2.5.2. If multiple simultaneous challenges are presented in the same procedure at the same time, the challenges will be processed through the formation of a single Challenge Committee, which will analyze the challenges individually, issuing individual decisions for each challenged Arbitrator.

1.2.5.2.1. In the case dealt with in the previous item, the fees of each of the Members of the Challenge Committee, as indicated in the CAMARB Schedule of Costs[7], will be calculated per challenged Arbitrator.

1.2.6. Regarding expert fees, in addition to observing the time frame set out in the approved expert proposal and/or in the Procedural Order that approves it, the Secretariat must obtain express approval from the Arbitration Court to release the installments due to the professional.

1.3. Payment of fees to Arbitrators, Emergency Arbitrators, Mediators, Members of CPRD Committees, Members of Challenge Committees and Experts may be made to their natural person or through a professional society of which the professional is a member, provided that this is included in its corporate purpose.

1.4.1. The CAMARB Executive Board will be responsible for deliberating on the request for payment of the Chamber's administrative fees in installments.

1.4.2. If the request for payment in installments is submitted during the administrative phase (i.e., before the formation of the Arbitration Tribunal or before the professional assumes the commitment in the procedure), the CAMARB Executive Board may accept or propose a new form of payment in installments to the Parties. Such measure will be subject to consultation of the Arbitrators' agreement as soon as they express acceptance of the invitation to act in the procedure in question.

1.4.3. The CAMARB Secretariat will proceed with collections or control of payments of installments according to the professional's acceptance or refusal.
