The interest is expressed in the prelim offering itself.  Everyone is on notice that they are interested.

Certain of our executive officers and directors have indicated an interest in purchasing an aggregate of up to $ of our common shares and warrants in this offering at the public offering price and on the same terms as other purchasers in this offering. However, because indications of interest are not binding agreements or commitments to purchase, the underwriter may determine to sell more, fewer or no common shares and warrants in this offering to any of those executive officers and directors, or any or all of those executive officers and directors may determine to purchase more, fewer or no common shares and warrants in this offering.

PLUS, they are prohibited from selling them for 60 days hence:

We, and our executive officers and directors, have agreed to a 60-day “lock-up” with respect to the common shares and other of our securities such parties beneficially own, including securities that are convertible into common shares and securities that are exchangeable or exercisable for common shares, subject to certain exceptions. This means that, subject to certain exceptions, for a period of 60 days following the date of this prospectus supplement, we and such persons may not offer, sell, contract to sell, hypothecate, pledge or otherwise dispose of these securities without the prior written consent of Maxim. In addition, subject to certain exceptions, we have agreed to not issue any securities that are subject to a price reset based on the trading prices of our common shares or upon a specified or contingent event in the future, or enter into any agreement to issue securities at a future determined price for a period of six months following the closing date of this offering. The terms of the lock-up agreements and prohibition may be waived by the underwriter at its discretion, although the underwriter has no present intention to waive or shorten either of the lock-up and prohibition periods. 

I strongly recommend everyone read the Prelim. Prospectus several times.  A lot of misunderstanding and misinformation on here can be eliminated  and a coherent understanding of what is being offered can be achieved universally.  Once that understanding has been acheived the dialog on here can move on to how best position oneself in front of this offering.  I think as adults, the emotional explosions should all by now have been detonated and the group can work together for its mutual benefit.
