If Resverlogix owed $300K to BLG for legal services....after all, BLG is listed as the company's "counsel" in this pdf from 2013:

 A dissenting Resverlogix Shareholder must send to Resverlogix, c/o its counsel, Borden Ladner Gervais LLP

https://www.resverlogix.com/upload/media_element/166/01/information-circular-05-01-2013.pdf

Then BLG' involvement in "the transaction" coud be direct involvement the way I see it...simply being the receipient of $300,000 worth of RVX shares.
