Synergy Resources Increases Proved Reserves by 40% in Its Mid-Year Update
--------------------------------------------------------------------------------

PLATTEVILLE,  CO -- (Marketwired) -- 05/21/13 -- Synergy  Resources  Corporation
(NYSE MKT:  SYRG),  Platteville,  CO,  announced  that its third  party  reserve
engineer, Ryder Scott Company, has evaluated the company's mid-year reserves for
the period ending  February 28th, 2013 and reported a PV10 value of $208 million
on proved  reserves of 13.63 million  barrels of oil  equivalent  (BOE) versus a
PV10 value of $148 million and 10.66  million BOE for the period  ending  August
31st,  2012.  The largest  increase in the reserves was in the Proved  Developed
Producing  (PDP)  category  which  rose  60%.  There was an  increase  in Proved
Developed  Not  Producing  (PDNP)  reserves  of 33% and an  increase  in  Proved
Undeveloped (PUD) reserves of 9%.

Monty  Jennings,  CFO of  Synergy  Resources,  commented,  "We  are  pleased  to
demonstrate  continuing growth in our proved reserve base. The large increase in
PDP reflects our acquisition of producing  properties and our ability to convert
unproved  acreage to proved  reserves  through  our  drilling  activities.  This
evaluation is based  primarily on vertical wells and only 2.7% of the PV10 value
in the reserve report is attributed to horizontal  wells.  We believe there is a
great deal of un-booked  potential  reserve  value in our leased  acreage in the
Wattenberg  Field and the  Northern  DJ Basin.  We intend to prove up that value
which is not reflected on our reserve report through drilling of both horizontal
and vertical wells."

The reserve estimates were prepared in accordance with guidelines established by
the United  States  Securities  and  Exchange  Commission  for proved  reserves.
Probable and  possible  reserves  are  excluded.  Prices are based on a trailing
twelve  month  average and are held  constant  over the life of the  properties.
Similarly, costs are held constant for the duration of the well.
