Contracts to deal with emergency situations may be awarded without a bidding process.

Only bidders are allowed in all of the bidding process.

The Portuguese word for public biddings is alienações.

In a public bidding, all conditions being the same, Brazilian companies have preference over foreign ones if there is a tie.

"others" (l.12) stands for other big businesses.

"those" (L.11) refers to "public companies" (L.11).

By no means shall any bids be expressed in foreign currency.

Public companies are exempt from the bidding process.

However low a price bid may be, it still may not be the winner if technical factors are not up to standards.
