We have obtained the information on the captioned topic by our correspondent in Buenos Aires, Pandi
Liquidadores S.R.L.. Please find the attached notice issued by local Coast Guard and free English translation

In addition to the normal “under keel clearance”(UKC) 0.6m for vessels with drafts over 10.36m in River
Plate basin and River Parana, some extra UKC will be required as below,
1. Section Parana River (Timbues – San Martin – San Lorenzo Ports) – Parana de las Palmas River up toKm. 57:
1-1. For drafs equal or over 10.37 and up to 10.49 meters, an increase of THREE centimeters (3 cm) per
additional centimeter of draft.1-2. For drafts equal or over 10.50 meters, TEN per cent (10%) of the static draft.2. Section Parana de las Palmas River from Km. 57 up to Recalada Pilot Station:
2-1. For drafts equal or over 10.37 and up to 10.67 meters, an increase of ONE COMMA FIVEcentimeters (1,5 cm) per additional centimeter of draft.2-2. For drafts equal or over 10.68 meters, TEN per cent (10%) of the static draft.3. In both cases, thousandths shall be rounded to the nearest whole hundredths, that is, if the number ends
in five (5) or higher, it shall be rounded up and if it is four (4) or less, it shall be rounded down.We hope it will be of help to you with regard to the safe voyage.

In view of the presentation performed by the Under Secretariat of Ports and Waterways regarding
the request for amendment of the safety under keel safety clearance determined by Disposition
SNAV; NA9 No 028/2007, informed by the Navigation Safety Office, and:CONSIDERING:
That the Disposition SNAV, NA9 No 028/07 complementing Ordinance No 04/00 and theNavigation Regulations in Title 3, Chapter 01 of the Sea, River and Lake Navigation Code(REGINAVE), established security under keel safety clearance additional to 0.60 meters for vessels
over 10.36 meters drafts, that shall sail the Main Channels between San Martín San Lorenzo andthe Recalada Pilot Station.
That during the Meeting of the Navigation Technical-Administrative Advisory Council, held onJune 9th of this year, in which different actors of the shipping industry took part, it was discussed
and agreed among other topics the convenience of increasing the under keel safety clearance.
That the National Deputy Secretariat of Ports and Waterways, by Note No NO-2016-01351477APN, dated September 13th of this year, suggested an increase in current under keel safety clearance
when vessels shall exceed the maximum draft of 10.36 meters, in order to enable the absorption of
the increase in drafts by the dynamic effects that occur in navigation at speeds compatible withgood management and maneuverability of vessels.
That on the other hand, such increase in safety conditions shall allow to consider the requirementsof users of such waterways for greater safety margins tending thus to a more rational, safe andefficient use of it, mainly taking into account the different and evolutionary factors and effects thatincluence the determination.
That analyzing the above problems, it becomes feasible to determine new safety parameters
additional and complementary to Ordinance No: 04/00 (DPSN), in order to minimize potential risks
and thus maintain the standards from the point of view of navigation safety, environmental
preservation and traffic management.
That this Maritime Authority is empowered to regulate the navigation in National Jurisdiction
waters, as per established in articles 31, 34 and 39 of Law No 20.094 (Navigation Law), as well as
article 5 Paragraph a) item 2º of Law No 18.398 (Argentine Coast Guard Code).
