RE: Company Update:  Q4 2008

Dear Investor:

The 4th quarter of 2008 continued the significant progress we achieved throughout the year.  As you already know, this
quarter has most likely presented the toughest fund raising and business environment ever – certainly in our lifetime.
However, we have taken appropriate steps, finding ways to bring products to market faster and at lower cost.  Although
times are tough, we have significantly lowered our investment capital requirement and increased our commercial
opportunities.  While our resources have been limited, we are positioned to continue to make great forward progress.  It
is more critical than ever to uncover and attract new sources of investment capital as traditional sources have frozen.  
Each additional investment will hasten our success and we would be happy to follow-up with anyone who may have an
interest in investing.  Even in this difficult investment environment, PluroGen is poised to provide a terrific return.

We hope this update is informative, but please feel free to contact us if you have any questions.  We are grateful, and
thank you, for your interest as well as your investment.
