Subject: Resignation

 Gentlemen,

With a heavy  heart,  I must submit my immediate  resignation  from the board of
directors and officer of the company. It has been a very difficult decision, but
I feel it is time to move on from United Cannabis. I will stay on as an employee
for another two weeks to assist with the transition.

I am concerned  with the current path of the company and I feel that it is going
down a similar road that has been traveled  unsuccessfully  before. I brought an
opportunity  to the board of  directors on May 27th that would have cut overhead
significantly,  paid off our largest creditors (i.e. one of which is the Monfort
family  who has been very  friendly  and  tried to work with us) and would  have
taken us out of bankruptcy  with an operating  facility in Du Quoin and money to
operate.  That  proposal was rejected,  and it was decided that United  Cannabis
would proceed with a high-risk  tolling  agreement  with an untested third party
with questionable references and reputation. I accepted the vote and did my best
to fulfill the obligations that were agreed to by the board of directors. I have
increased production by over 100% over the last 30 days.

In addition,  our key managers and the pillars that helped build our processing,
testing and refinement  laboratories are now leaving or have resigned.  They all
voiced  concerns over the  trajectory  of the company and the chaotic  manner in
which  some  of our  organization's  leaders  conduct  business.  That  put  me
personally in a very challenging position. Not only do I have to try and replace
my core staff, but I also have to singlehandedly  complete the build outs of two
of the largest  facilities in the country,  which I objected to  constructing in
the first place.

I have tried to be the  conservative  voice of reason  through my seven years at
the  company.  I feel  that I have  continually  voiced  concerns  over  various
business  decisions over the years,  and I have been surprised  repeatedly  with
unilateral  decisions  that have been made  without  my  permission  or vote.  I
continue to be exposed to additional liability that I need to mitigate.

I have worked  diligently  over the last several weeks to improve our processing
capacity to give the company the best chance for success in the future.  I truly
want United  Cannabis to be successful and I take this decision very  seriously.
It is a very sad day for me considering how much time and effort I have put into
making United Cannabis a best in class hemp  processor.  I wish you all the best
of luck going forward.

 Yours Truly,

 Chadwick Ruby
