Sale/lease of intellectual property developed during BLM to a European builder?

But I don't think it has to just be sometime bought or sold, just a transaction. The US definition (couldn't find an AU source) is:

"Material Transaction means any material transaction in which the Company or any of its subsidiaries proposes to engage or is engaged, including a material purchase or sale of assets or securities, financing, merger, consolidation, tender offer or any other material transaction that would require disclosure pursuant to the Exchange Act, and with respect to which the board of directors of the Company reasonably has determined in good faith that compliance with this Agreement may reasonably be expected to either materially interfere with the Company’s or such subsidiary’s ability to consummate such transaction in a timely fashion or require the Company to disclose material, non-public information prior to such time as it would otherwise be required to be disclosed."
