Company Update:  Q1 2009

Despite the global economic slump, PluroGen hit a number of important milestones and achieved solid progress in the
1st quarter of 2009.  Unfortunately, the environments for business, in general, and fund raising, in particular, continue to
be difficult and we do not foresee much change over for the next several quarters.  In spite of that, however, PluroGen
is experiencing success with its strategy and tactics to bring products to market faster and at lower cost keeping with
our plan of significantly lower investment capital requirement and increased commercial opportunity.  Resources
continue to be limited but we are positioned, as you will read below, to continue making important forward progress.

Traditional sources of capital remain frozen.  Attracting new sources of investment remains a primary concern and
effort.  A good number of venture capital sources and early stage businesses have simply folded over the last several
quarters.  Within that environment, you will see PluroGen made progress in Q1 09 in fundraising - a real confirmation of
support and value in our business plan and opportunity for return on investment.  More investment is needed.  As
always, we are 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.
