The 6th–last page of the portfolio should contain scan of the contract for work for design proposal for the First round signed by the participant. The attached Contract is 7 A4 pages long. Does the Announcer expect us to attach all of the 7 pages or to shrink them to 1 A3 horizontal format – it might not be easy to read that way.
A real-size scan is preferable, which could mean that the contract would take 4 pages of the portfolio. However, no matter how many pages would the scanned contract take, the page limit is clear about the first five pages of the portfolio and then the scan is up to you.
