Business Operations 

Overview 

IsoRay  began  production  and  sales  of  Proxcelan  Cesium-131  (Cs-131)  brachytherapy  seeds  in  October 
2004 for the treatment of prostate cancer after clearance of its premarket notification (510(k)) by the Food 
and Drug Administration (FDA).  In December 2007, IsoRay began selling its Proxcelan Cs-131 seeds for 
the  treatment  of  ocular  melanoma.    Cs-131  could  also  be  applied  as  a  treatment  for  other  solid  tumor 
applications such as breast, lung, liver, brain and pancreatic cancer, expanding the total available market 
opportunity  for  Cs-131  brachytherapy.    Management  believes  its  Cs-131  technology  will  allow  it  to 
capture a major position in the brachytherapy market.  The beneficial characteristics of the Cs-131 isotope 
are expected to result in decreased radiation exposure to the patient and reduced severity and duration of 
side effects, while treating cancer cells as effectively as other isotopes used in seed brachytherapy. 

Brachytherapy seeds are small devices used in an internal radiation therapy procedure.  In recent years the 
procedure has become one of the primary treatments for prostate cancer.   The brachytherapy procedure 
places  radioactive  seeds  as  close  as  possible  to  (in  or  near)  the  cancerous  tumor  (the  word 
―brachytherapy‖  means  close  therapy).    The  seeds  deliver  therapeutic  radiation  thereby  killing  the 
cancerous  tumor  cells  while  minimizing  exposure  to  adjacent  healthy  tissue.    This  procedure  allows 
doctors to administer a higher dose of radiation directly to the tumor.  Each seed contains a radioisotope 
sealed  within  a  welded  titanium  capsule.    When  brachytherapy  is  the  only  treatment  (monotherapy), 
approximately  70  to  120  seeds  are  permanently  implanted  in  the  prostate  in  an  outpatient  procedure 
lasting  less  than  one  hour.    When  brachytherapy  is  combined  with  external  beam  radiation  or intensity 
modulated  radiation  therapy  (dual  therapy),  then  approximately  40-80  seeds  are  used  in  the  procedure. 
The isotope decays over time and eventually the seeds become inert.  The seeds may be used as a primary 
treatment  or  in  conjunction  with  other  treatment  modalities,  such  as  chemotherapy,  or  as  treatment  for 
residual disease after excision of primary tumors. 

Management  believes  that  the  IsoRay  Proxcelan  Cesium-131  brachytherapy  seed  represents   the  first 
major advancement in brachytherapy technology in over  20 years with attributes that could make it the 
long-term  ―seed  of  choice‖  for  internal  radiation  therapy  procedures.    The  Cs-131  seed  has  an  FDA 
cleared 510(k) for treatment of malignant disease (e.g. cancers of the head and neck,  brain, liver, lung, 
breast, prostate, etc.) and may be used in surface, interstitial, and intracavity applications for tumors with 
known radiosensitivity. 

Increasingly, prostate cancer patients and their doctors who decide on seed brachytherapy choose Cs-131 
because  of  its  significant  advantages  over  Palladium-103  (Pd-103)  and  Iodine-125  (I-125),  two  other 
isotopes currently in use.  These advantages include: 

Higher Energy 
Cs-131  has  a  higher  average  energy  than  any  other  commonly  used  prostate  brachytherapy 
isotope  on  the  market.   Energy  is  a  key  factor  in  how  uniformly  the  radiation  dose  can  be 
delivered throughout the prostate.  This is known as homogeneity.  Early studies demonstrate Cs-
131  implants  are  able  to  deliver  the  required  dose  while  maintaining  homogeneity  across  the 
gland itself and potentially reducing unnecessary dose to critical structures such as the urethra and

rectum.  (Prestidge  B.R.,  Bice  W.S.,  Jurkovic  I.,  et  al.  Cesium-131  Permanent  Prostate 
Brachytherapy:   An  Initial  Report.   Int.  J.  Radiation  Oncology  Biol.  Phys.  2005:   63  (1)  5336-
5337.) 

             Shorter Half-Life 

Cs-131  has  the  shortest  half-life  of  any  commonly  used  prostate  brachytherapy  isotope  at  9.7 
days.  Cs-131 delivers 90% of the prescribed dose in just 33 days compared to 58 days for Pd-103 
and 204 days for I-125.  The short half-life of Cs-131 reduces the duration of time during which 
the patient experiences the irritating effects of the radiation. 

Improved Coverage of the Prostate 
Permanent prostate brachytherapy utilizing Cs-131 seeds allows for better dose homogeneity and 
sparing of the urethra and rectum while providing comparable prostate coverage compared to I-
125 or Pd-103 seeds with comparable or fewer seeds and needles. (R Yang, J Wang, Dosimetric 
Comparison  of  Permanent  Prostate  Brachytherapy  Plans  Utilizing  Cs-131,  I-125  and  Pd-103 
Seeds. Abstract presented at the AAPM Annual Meeting, July 2008, Houston TX) 

Rapid Resolution of Side effects 
Studies  demonstrate  that  objective  measures  of  common  side-effects  showed  an  early  peak  in 
symptoms in the 2-week to 1-month time frame.  Resolution of morbidity resolved rapidly within 
4-6 months. (Prestidge B, et. al., Clinical Outcomes of a Phase-II, Multi-institutional Cesium-131 
Permanent Prostate Brachytherapy Trial. Brachytherapy. 2007: 6 (2); Prestidge B, et al. Cesium-
131 Permanent Prostate Brachytherapy:  An Initial Report.  Int. J. Radiation Oncology Biol. Phys. 
2005:  63 (1) 5336-5337) 

            Higher Biologically Effective Dose 

Another benefit to the short half-life of Cs-131 is what is known as the ―biological effective dose‖ 
or BED.  BED is a way for health care providers to predict how an isotope will perform against 
slow  versus  fast  growing  tumors.   Studies  have  shown  Cs-131  is  able  to  deliver  a  higher  BED 
across  a  wide  range  of  tumor  types  than  either  I-125  or  Pd-103.  Although  prostate  cancer  is 
typically  viewed  as  a  slow  growing  cancer  it  can  present  with  aggressive  features.   Cs-131‘s 
higher BED may be particularly beneficial in such situations.  (Armpilia CI, Dale RG, Coles IP et 
al.   The  Determination  of  Radiobiologically  Optimized  Half-lives  for  Radionuclides  Used  in 
Permanent  Brachytherapy Implants.  Int.  J.  Radiation  Oncology  Biol.  Phys.  2003;  55 (2):   378-
385.) 

PSA Control 
Investigators  tracking  PSA  in  both  single  arm  and  randomized  trials  have  concluded  Cs-131‘s 
PSA  response  rates  show  similar  tumor  control  to  I-125,  long  considered  the  gold  standard  in 
permanent seed brachytherapy. (Moran, B, et. al. Cesium-131 Prostate Brachytherapy‖ An Early 
Experience.  Brachytherapy.  2007;  6  (2).  Bice  W,  et.  al.    Recommendations  for  permanent 
prostate brachytherapy with 131Cs: a consensus report from the Cesium Advisory Group.  Oral 
Presentation at ABS Annual Meeting, May 2008, Boston MA) 

The following graph was presented in William Bice, PhD‘s presentation at the 2008 ABS Annual 
Meeting in May 2008 and shows Cs-131‘s PSA response rate compared to I-125 and Pd-103.

Industry Information 

Incidence of Prostate Cancer 

The prostate is a walnut-sized gland surrounding the male urethra, located below the bladder and adjacent 
to the rectum.  Prostate cancer is a malignant tumor that begins most often in the periphery of the gland 
and, like other forms of cancer, may spread beyond the prostate to other parts of the body.  According to 
the  American  Cancer  Society,  approximately  one  in  six  men  will  be  diagnosed  with  prostate  cancer 
during  his  lifetime.    It  is  the  most  common  form  of  cancer  in  men  after  skin  cancer,  and  the  second 
leading  cause  of  cancer  deaths  in  men.    The  American  Cancer  Society  estimates  there  will  be  about 
186,320  new  cases  of  prostate  cancer  diagnosed  and  an  estimated  28,660  deaths  associated  with  the 
disease in the United States in 2008.  Because of early detection techniques (e.g., screening for  prostate 
specific  antigen,  or  PSA),  approximately  nine  out  of  ten  prostate  cancers  are  found  in  the  local  and 
regional  stages  (local  means  it  is  still  confined  to  the  prostate;  regional  means  it  has  spread  from  the 
prostate to nearby areas, but not to distant sites, such as bone). 

Prostate  cancer  accounts  for  about  9%  of  cancer  related  deaths  in  men.    Prostate  cancer  incidence  and 
mortality  increase  with  age.    The  National  Cancer  Institute  has  reported  that  the  incidence  of  prostate 
cancer increases dramatically in men over the age of 55.  At the age of 70, the chance of having prostate 
cancer is 12 times greater than at age 50.

The American Cancer Society recommends that men without symptoms, risk factors and who have a life 
expectancy of at least ten years, should begin regular annual medical exams at the age of 50, and believes 
that health care providers should offer as part of the exam the prostate-specific antigen (PSA) blood test 
and a digital rectal examination.  The PSA blood test determines the amount of prostate specific antigen 
present in the blood.  PSA is found in a protein secreted by the prostate, and elevated levels of PSA can 
be associated with either prostatitis (a noncancerous inflammatory condition) or a proliferation of cancer 
cells in the prostate.   Transrectal ultrasound tests and biopsies are typically performed on patients with 
elevated PSA readings to confirm the existence of cancer.  Early screening has fostered a decline in the 
prostate cancer death rate since 1990.  When compared to men of the same age and race who do not have 
cancer (called relative survival), the 5-year relative survival rate for men when the cancer is found in the 
local and regional stages is nearly 100%. 

Brachytherapy 

There  is  a  large  potential  market  for  the  Company‘s  products.   Several  significant  clinical  and  market 
factors  are  contributing  to  the  increasing  popularity  of  the  brachytherapy  procedure.    Over  61,000 
procedures were forecasted to occur in the U.S. in 2007 (Source: iData Research, Inc., 2008).  IsoRay‘s 
management believes that the Proxcelan seed will add incremental growth to the existing brachytherapy 
seed  market  as  physicians  who  are  currently  reluctant  to  recommend  brachytherapy  for  their  prostate 
patients due, in part, to side effects caused by longer-lived isotopes, become comfortable with the shorter 
half-life of Cs-131, and the anticipated related reduction of side effects that it offers. 

In  1996  only  4%  of  prostate  cancer  cases  were  treated  with  brachytherapy,  or  about  8,000  procedures.  
The  number  of  brachytherapy  cases  has  consistently  increased  and  in  2007  approximately  61,000 
brachytherapy procedures were performed to treat prostate cancer. (Source: iData Research Inc., 2008) 

Minimally invasive brachytherapy has significant advantages over competing treatments including lower 
cost, equal or better survival data, fewer side effects, faster recovery time and the convenience of a single 
outpatient  implant  procedure  that  generally  lasts  less  than  one  hour  (Merrick,  et  al.,  Techniques  in 
Urology,  Vol.  7,  2001;  Potters,  et  al.,  Journal  of  Urology,  May  2005;  Sharkey,  et  al.,  Current  Urology 
Reports, 2002). 

Management expects that market growth in all brachytherapy in the U.S. will increase at the rate of 4% 
per  year  through  2011.    Independent  research  firms  have  estimated  Cs-131  growth  alone  in  the  U.S. 
marketplace to average 32% a year from 2009 through 2014 (Source: iData Research Inc., 2008).  The 
competing isotopes Pd-103 and I-125 are projected to decrease by .5% and increase 1.6% respectively per 
year during this same time period (Source: iData Research Inc., 2008). 

Treatment Options and Protocol 

In addition to brachytherapy, localized prostate cancer can be treated with prostatectomy surgery (RP for 
radical  prostatectomy),  external  beam  radiation  therapy  (EBRT),  intensity  modulated  radiation  therapy 
(IMRT),  dual  or  combination  therapy,  high  dose  rate  brachytherapy  (HDR),  cryosurgery,  hormone 
therapy,  and  watchful  waiting.    The  success  of  any  treatment  is  measured  by  the  feasibility  of  the 
procedure for the patient, morbidities associated with the treatment, overall survival, and cost.  When the 
cancerous tissue is not completely eliminated, the cancer typically returns to the primary site, often  with 
metastases to other areas of the body. 

Prostatectomy  Surgery  Options.    Historically  the  most  common  treatment  option  for  prostate  cancer, 
radical  prostatectomy  is  the  removal  of  the  prostate  gland  and  some  surrounding  tissue  through  an 
invasive  surgical  procedure.    RP  is  performed  under  general  anesthesia  and  involves  a  hospital  stay  of 
three days on average for patient observation and recovery.  Possible side affects of RP include impotence 
and incontinence.  According to a study published in the Journal of the American Medical Association in 
January 2000,  approximately  60%  of  men  who  had  a  RP  reported  erectile  dysfunction  as  a  result  of 

5 

 
 
 
 
 
 
 
 
 
 
surgery.    This  same  study  stated  that  approximately  40%  of  the  patients  observed  reported  at  least 
occasional  incontinence.    New  methods  such  as  laparoscopic  and  robotic  prostatectomy  surgeries  are 
currently being used more frequently in order to minimize the nerve damage that leads to impotence and 
incontinence,  but  these  techniques  require  a  high  degree  of  surgical  skill.    RP  and  laparoscopic 
prostatectomy are projected to decrease approximately 31% in the U.S. from the 2004 high of 66,567 to 
20,838 procedures in 2014.  However, robotic surgeries are projected to more than replace the decrease in 
the RP and laparoscopic procedures (Source: iData Research Inc., 2008). 

Primary External Beam Radiation Therapy.  EBRT involves directing a beam of radiation from outside 
the body at the prostate gland to destroy cancerous tissue.  EBRT treatments are received on an outpatient 
basis  five  days  per  week  usually  over  a  period  of  eight  or  nine  weeks.    Some  studies  have  shown, 
however,  that  the  ten-year  disease  free  survival  rates  with  treatment  through  EBRT  are  less  than  the 
disease  free  survival  rates  after  RP  or  brachytherapy  treatment.    Side  effects  of  EBRT  can  include 
diarrhea, rectal leakage, irritated intestines, frequent urination, burning while urinating, and blood in the 
urine.  Also the incidence of incontinence and impotence five to six years after EBRT is comparable to 
that for surgery.  EBRT procedures are projected to increase slightly from 22,000 procedures in 2006 to 
24,900 in 2012 (Source: Millennium Research Group, 2008). 

Intensity Modulated Radiation Therapy.  IMRT is considered a more advanced form of EBRT in which 
sophisticated computer control is used to aim the beam at the prostate from multiple different angles and 
to vary the intensity of the beam.  Thus, damage to normal tissue and critical structures is minimized by 
distributing the unwanted radiation over a larger geometric area.   This course of treatment is similar to 
EBRT and requires daily doses over a period of seven to eight weeks to deliver the total dose of radiation 
prescribed  to  kill  the  tumor.    Because  IMRT  is  a  new  treatment,  less  clinical  data  regarding  treatment 
effectiveness and the incidence of side effects is available.  One advantage of IMRT, and to some extent 
EBRT,  is  the  ability  to  treat  cancers  that  have  begun  to  spread  from  the  tumor  site.    An  increasingly 
popular  therapy  for  patients  with  more  advanced  prostate  cancer  is  a  combination  of  IMRT  with  seed 
brachytherapy,  known  as  combination  or  dual  therapy.    IMRT  in  the  U.S.  (including  dual  therapy)  is 
projected to  grow  9%  per year  from  31,500  procedures  in  2007  to  48,500  procedures  in  2012 (Source: 
Millennium  Research  Group,  2008).    IMRT  is  generally  more  expensive  than  other  common  treatment 
modalities. 

Dual or Combination Therapy.   Dual therapy is the combination of IMRT or 3-dimensional conformal 
external  beam  radiation  and  seed  brachytherapy  to  treat  extra-prostatic  extensions  or  high  risk  prostate 
cancers  that have  grown  outside the  prostate.    Combination  therapy  treats  high  risk  patients  with a full 
course of IMRT or EBRT over a period of several weeks.  When this initial treatment is completed, the 
patient must then wait for several more weeks to months to have the prostate seed implant. 

With the arrival of Proxcelan Cs-131, with its short half life, patients may now complete their course of 
treatment sooner and have shorter duration of side-effects.  Management estimates that at least 30% of all 
prostate implants are now dual therapy cases. 

High  Dose  Rate  Temporary  Brachytherapy.    HDR  temporary  brachytherapy  involves  placing  very  tiny 
plastic  catheters  into  the  prostate  gland,  and  then  giving  a  series  of  radiation  treatments  through  these 
catheters.   The  catheters are  then  removed,  and  no radioactive  material is left  in  the  prostate  gland.   A 
computer-controlled  machine  inserts  a  single  highly  radioactive  iridium  seed  into  the  catheters  one  by 
one.  This procedure is typically repeated at least three times while the patient is hospitalized for at least 
24  hours.    HDR  is  projected  to  grow  approximately  1.3%  per  year  from  26,200  procedures  in  2007 
through 2012 (Source: Millennium Research Group, 2008). 

Cryosurgery.  Cryosurgery involves placing cold metal probes into the prostate and freezing the tissue in 
order to destroy the tumor.  Cryosurgery patients typically stay in the hospital for a day or two and have 
had  higher  rates  of  impotence  and  other  side  effects  than  those  who  have  used  seed  implant 
brachytherapy.  Market research firms project that cryosurgery will grow steadily through 2012.  To date 
the market has remained almost flat (Source: Millennium Research Group, 2008).

Additional  Treatments.    Additional  treatments  include  hormone  therapy  and  chemotherapy.    Hormone 
therapy  is  generally  used  to  shrink  the  tumor  or  make  it  grow  more  slowly  but  will  not  eradicate  the 
cancer.  Likewise, chemotherapy will not eradicate the cancer but can slow the tumor growth.  Generally, 
these treatment alternatives are used by doctors to extend patients‘ lives once the cancer has reached an 
advanced stage or in conjunction with other treatment methods.  Hormone therapy can cause impotence, 
decreased  libido,  and  breast  enlargement.    Most  recently,  hormone  therapy  has  been  linked  to  an 
increased risk of cardiovascular disease in men with certain pre-existing conditions such as heart disease 
or diabetes.  Chemotherapy can cause anemia, nausea, hair loss, and fatigue. 

Watchful  Waiting.    Watchful  waiting  is  not  a  treatment  but  might  be  suggested  by  some  healthcare 
providers  depending  on  the  age  and  life  expectancy  of  the  patient.    Watchful  waiting  may  be 
recommended if the cancer is diagnosed as localized and slow growing, and the patient is asymptomatic.  
Generally, this approach is chosen when patients are trying to avoid the side affects associated with other 
treatments or when they are not candidates for current therapies due to  other health issues.  Healthcare 
providers will carefully monitor the patient‘s PSA levels and other symptoms of prostate cancer and may 
decide on active treatments at a later date. 

Brachytherapy Clinical Results 

Long-term  survival  data  is  now  available  for  brachytherapy  with  I-125  and  Pd-103,  which  support  the 
efficacy of brachytherapy.  Clinical data indicate that brachytherapy offers success rates for early-stage 
prostate cancer treatment that are equal to or better than those of RP or EBRT.  While clinical studies of 
brachytherapy  to  date  have  focused  primarily  on  results  from  brachytherapy  with  I-125  and  Pd-103, 
management believes that these data are also relevant for brachytherapy with Cs-131.  In fact, it appears 
that  Cs-131  offers  improved  clinical  outcomes  over  I-125  and  Pd-103,  given  its  shorter  half-life  and 
higher energy. 

Improved patient outcomes.  A number of published studies on the use of I-125 and Pd-103 brachytherapy 
in the treatment of early-stage prostate cancer have been very positive, the most recent of which was as 
follows: 

  Results of a trial published in 2007 in the International Journal of Radiation Oncology looking at 
15-year survival in 223 patients with stage T1-T3 prostate cancer and treated with brachytherapy 
in  combination  with  external  beam  demonstrated  excellent  long-term  biochemical  control.  
Fifteen-year  biochemical  relapse  free  survival  (BRFS)  for  the  entire  treatment  group  was  74%.  
(Sylvester  J.  et  al.  ―15-year  biochemical  relapse  free  survival  in  clinical  stage  T1-T3  prostate 
cancer following  combined  external beam  radiotherapy  and  brachytherapy;  Seattle  experience‖, 
Int. J. Rad. Onc. Biol., Vol. 67, 2007, 57-64.). 

Reduced Incidence of Side Effects.  Sexual potency and urinary incontinence are two major concerns men 
face  when  choosing  among  various  forms  of  treatment  for  prostate  cancer.    Because  the  Proxcelan 
Cesium-131 brachytherapy seed delivers a highly concentrated and confined dose of radiation directly to 
the  prostate,  healthy  surrounding  tissues  and  organs  typically  experience  less  radiation  exposure.  
Management believes, and initial results appear to support, that this should result in lower incidence of 
side  effects  and  complications  than  may  be  incurred  with  other  conventional  therapies  or  isotopes.  
Additionally when side effects do occur, they should resolve more rapidly than those experienced with I-
125 and Pd-103 isotopes. 

Cs-131 Clinical Results and Ongoing Trials 

A Cs-131 monotherapy trial for the treatment of prostate cancer was fully enrolled in February 2007.  The 
trial was a 100 patient multi-institutional study to observe the dosimetric characteristics of Cs-131 and its 
side  effect  profile.   The  results  of  the  monotherapy  trial  have  demonstrated  that  Cs-131  is  a  viable 

7 

 
 
 
 
 
 
 
 
 
 
alternative as an isotope for permanent seed prostate brachytherapy.  Some of the significant and specific 
findings were as follows: 

  Patient reported symptoms (IPSS Scores) were mild to moderate with relatively rapid resolution 

within 4-6 months.  

II,  multi-institutional  Cesium-131  permanent  prostate  brachytherapy 

  Prostate Specific Antigen, or PSA, response over 30 months has been very encouraging to date 
with similar tumor control rates to that of I-125.  (Prestidge BR, Bice WS, ―Clinical outcomes of 
trial‖. 
a  Phase 
Brachytherapy, Volume  6,  Issue  2, April-June  2007, Page  78)  (Moran  BJ,  Braccioforte  MH, 
―Cesium-131  prostate  brachytherapy:  An  early  experience‖.  Brachytherapy, Volume  6,  Issue 
2, April-June  2007, Page  80).  (Bice,  W,  et.  al.  ―Recommendations  for  permanent  prostate 
brachytherapy  with  131Cs:  a  consensus  report  from  the  Cesium  Advisory  Group‖.  Oral 
Presentation at ABS Annual Meeting, May 2008, Boston MA). 

  The resolution of acute side effects proved to be much quicker with Cs-131 compared to I-125 
thus validating the theoretical argument that dose related side effects dissipate faster with shorter 
lived  isotopes.   (Prestidge  BR,  ―Cesium-131;  the  isotope  of  choice  in  permanent  prostate 
brachytherapy‖.   Oral  Presentation  at  the  American  Brachytherapy  Society  annual  conference, 
April 2007.).  

  The dosimetric observations of the trial demonstrated that it was possible to deliver adequate dose 
to the prostate while maintaining dose uniformity across the gland.  The dose delivered to critical 
structures  was  well  within  acceptable  limits.  (Bice  WS,  Prestidge  BR,  ―Cesium-131  permanent 
prostate  brachytherapy:  The  dosimetric  analysis  of  a  multi-institutional  Phase  II  trial‖.  
Brachytherapy 2007(6); 88-89.).  

The  monotherapy  Cs-131  trial  will  continue  to  follow  patients  with  annual  updates  on  symptoms  and 
patient long-term survival data. 

The  prospective  randomized  monotherapy  trial  headed  by  Dr.  Brian  Moran  of  The  Chicago  Prostate 
Cancer  Center  directly  compared  Cs-131  to  I-125  PSA  response  and  treatment  related  morbidities 
following brachytherapy for localized carcinoma of the prostate in low to intermediate risk patients.  Dr. 
Moran  concluded  that  prostate  brachytherapy  with  Cs-131  is  effective  and  well-tolerated;  both  PSA 
response  and  acute  morbidity  profile  are  very  encouraging.    Dr.  Moran  will  continue  to  track  these 
patients in order to collect long-term outcomes. 

A  third  ongoing  study  first  presented  at  the  American  Association  of  Physicists  in  Medicine  (AAPM) 
meeting in July 2007 compared the dosimetry of Cs-131 and Pd-103 directly.  The study showed a 17.5% 
reduction in the number of seeds, 6% reduction in planned needles, 35.5% reduction in V150 (percent of 
gland that receives more than 150% of the prescription dose), and 44.2% reduction in R100 (percent of 
rectal  tissue  that  receives  the  full  prescription  dose  of  radiation).   (Musmacher,  J.,  ―Dosimetric 
comparison of Cesium-131 and Palladium-103 for permanent prostate brachytherapy‖, poster presented at 
49th AAPM Annual Conference, Minneapolis, MN, April 22-26, 2007.) 

Recently  accepted  for  publication  was 
the  Cs-131  Advisory  Group‘s  (CAG)  article  entitled 
―Recommendations for permanent prostate brachytherapy with 131Cs: a consensus report from the Cesium 
Advisory  Group‖.    The  objective  of  the  article  was  to  provide  consensus  recommendations  for  Cs-131 
prostate  brachytherapy  based  on  experience  to  date  for  physicians  still  unfamiliar  with  Cs-131.    The 
recommendations  are  based  on  three  clinical  trials,  one  of  which  has  completed  accrual  and  has  been 
published  in  the  peer  reviewed  literature,  and  combined  CAG  experience  of  more  than  1,200  Cs-131 
implants.  The recommendations from the group are designed to aid practitioners in the safe and effective 
delivery  of  Cs-131  prostate  brachytherapy.    The  Consensus  Paper  is  slated  to  be  published  in 
Brachytherapy in the fourth quarter of calendar year 2008.  The CAG is sponsored by the Company. 

The Company has also commissioned a dual therapy protocol.  This multi-institutional trial observes the 
dosimetric  characteristics  of  Cs-131  and  health  related  quality  of  life  (HRQOL)  results  following 
combined  Cs-131  transperineal  permanent  prostate  brachytherapy  and  external  beam  radiotherapy  in 
patients  with  intermediate  to  high  risk  prostate  cancer.   This  protocol  is  being  conducted  to  confirm 

8 

 
 
 
 
 
 
clinically what radiobiological data suggests regarding this treatment modality.  The quantified dosimetric 
variables collected  will be correlated  to  the  reported HRQOL  data  and  ultimately  compared  to  existing 
data in the literature for similar investigations using I-125 and Pd-103.  Patient enrollment for this study 
began in April 2007 and to date 50 patients have been enrolled. 

In  addition  to  establishing  the  dosimetric  and  quality  of  life  impact  of  Proxcelan  Cesium-131 
brachytherapy  seeds  in  different  treatment  modalities,  all  trials  have  been  designed  to  collect  ongoing 
PSA  results  for  the  purposes  of  establishing  long-term  survival  rates  using  Cs-131  seed  implant 
brachytherapy. 

Our Strategy 

The key elements of IsoRay‘s strategy for fiscal year 2009 include: 

  Continue to introduce the Proxcelan Cs-131 brachytherapy seed into the U.S. market.  Utilizing 
our direct sales organization, IsoRay intends to continue expanding the use of Proxcelan Cs-131 
seeds  in  brachytherapy  procedures  for  prostate  cancer  by  increasing  the  number  of  treatment 
centers offering Cs-131 and increasing the number of patients treated at each center using Cs-131.  
IsoRay hopes to capture much of the incremental market growth in seed implant brachytherapy 
and take market share from existing competitors. 

  Develop an enriched barium manufacturing process.  Working with leading scientists, IsoRay is 
working  to  design  and  create  a  proprietary  process  for  manufacturing  enriched  barium,  a  key 
source  material  for  Cs-131.    This  will  ensure  adequate  future  supply  of  Cs-131  and  greater 
efficiencies in producing the isotope. 

 

Introduce  Cs-131  therapies  for  other  cancers.    The  Company‘s  first  sale  for  ocular  melanoma 
occurred in late 2007 and periodic sales have occurred since then.  Although the ocular melanoma 
market  is  not  a  large  one,  this  continues  to  support  the  application  of  Cs-131  in  other  solid 
tumors.    IsoRay  will  continue  to  explore  partnering  with  other  companies  to  develop  the 
appropriate  technologies  and  therapeutic  delivery  systems  for  treatment  of  other  solid  tumors 
such as breast, lung, liver, pancreas, neck, and brain cancers.   

  Support clinical research and sustained product development.  The Company plans to structure 
and support clinical studies on the therapeutic benefits of Cs-131 for the treatment of solid tumors 
and  other  patient  benefits.    We  are  and  will  continue  to  support  clinical  studies  with  several 
leading  radiation  oncologists  to  clinically  document  patient  outcomes,  provide  support  for  our 
product claims, and compare the performance of our seeds to competing seeds.  IsoRay plans to 
sustain  long-term  growth  by  implementing  research  and  development  programs  with  leading 
medical institutions in the U.S. and other countries to identify and develop other applications for 
IsoRay‘s core radioisotope technology. 

 

 

Improve  our  manufacturing  efficiencies.    Over  the  past  several  months  the  Company  has  been 
working on improving its gross margin by reviewing its manufacturing processes.  Over the next 
year,  the  Company  will  continue  reviewing  its  manufacturing  processes,  implementing 
improvements,  and  automating  either  certain  portions  or  all  of  its  manufacturing  process.  
Management  believes  that  it  will  be  able  to  lower  its  costs  of  production  relative  to  its  sales 
revenue through this evaluation. 

Introduce Proxcelan Cesium-131 brachytherapy seeds to the Canadian and Russian market.  In 
August 2008, the Company obtained its ISO 13485 certification.  This was an important step to 
allow  the  Company  to  register  and eventually  sell its  Proxcelan  Cs-131  brachytherapy  seeds in 
Canada  and  Russia.    The  Company  anticipates  finalizing  its  registrations  of  Proxcelan  Cs-131 
brachytherapy  seeds  in  Canada  and  Russia  during  fiscal  year  2009.    The  Company  is  now 
focusing on the Canadian and Russian markets and is no longer pursuing sales in the European 

9 

 
 
 
 
 
 
 
 
 
 
Union (EU).  Management does not believe a strategic alliance with IBt, SA, a Belgian company, 
will be consummated nor will management leverage IBt‘s distribution channels in the EU. 

Products 

IsoRay markets the Proxcelan Cs-131 brachytherapy seed for the treatment of prostate cancer and ocular 
melanomas,  and  intends  to  market  Cs-131  for  the  treatment  of  other  malignant  disease  in  the  future.  
Additionally, the Company may market other radioactive isotopes in the future. 

Competitive Advantages of Proxcelan Cs-131 

General.  Management believes that the Proxcelan Cesium-131 brachytherapy seed has specific clinical 
advantages for treating cancer over I-125 and Pd-103, the other isotopes currently used in brachytherapy 
seeds.  The table below highlights the key differences of the three seeds.  The Company believes that the 
short  half-life,  high-energy  characteristics  of  Cs-131  will  increase  industry  growth  and  facilitate 
meaningful penetration into the treatment of other forms of cancer such as lung cancer.

Shorter  half-life.   The  Company  believes  that  Cs-131‘s  shorter  half-life  of  9.7  days  will  prove  to  have 
greater  biological  effectiveness,  will  mitigate  the  negative  effects  of  long  radiation  periods  on  healthy 
tissue, and will reduce the duration of any side effects.  Our early clinical data supports the Company‘s 
belief  that  there  is  a  reduced  duration  of  side  effects  post  implant.    A  shorter  half-life  produces  more 
intense therapeutic  radiation  over  a  shorter  period  of time  and  may  reduce the  potential  for  cancer  cell 
survival  and  tumor  recurrence.    Radiobiological  studies  indicate  that  shorter-lived  isotopes  are  more 
effective  against  faster  growing  tumors  (Dicker,  et.  al.,  Semin.  Urol.  Onc.  18:2,  May  2000).    Other 
researchers  conclude  that  ―half-lives  in  the  approximate  range  4-17  days  are  likely  to  be  significantly 
better  for  a  wide range  of tumor  types  for  which the radiobiologic characteristics  may  not  be  precisely 
known in advance.‖ (Armpilia CI, et. al., Int. J. Rad. Oncol. Biol. Phys. 55:2, February 2003). 

Higher energy.  The Cs-131 isotope average decay energy of  30.4 keV (versus 21 keV for Pd-103 and 
28.5  keV  for  I-125)  generates  a  therapeutic  radiation  field  that  extends  beyond  the  current  dosimetry 
reference point of one centimeter.  Pd-103 seeds emit radiation that does not penetrate as far into tissue 
(up  to  40%  lower  than  Cs-131).    To  compensate  for  this  lack  of  penetration,  more  Pd-103  seeds  are 
required to attain the equivalent dose than are required for Proxcelan seeds.  This increase in the number 
of seeds implanted increases the time and cost required to perform Pd-103-based procedures. 

Quality  of  Life.   Because  IsoRay‘s  Proxcelan  Cesium-131  brachytherapy  seed  delivers  a  highly 
concentrated  and  confined  dose  of  radiation  directly  to  the  prostate,  healthy  surrounding  tissues  and 
organs are exposed to less radiation than with other treatments.  Initial results indicate that the side effects 
experienced, if any, are mild to moderate and urinary symptoms resolve more rapidly, within 4-6 months, 
when compared to I-125.  Management believes that as the data matures it will continue to support fewer 
and less severe side effects and complications when compared to other conventional therapies.

Shape of radiation field.  The shape of the radiation field generated by a Proxcelan seed is more uniform 
than  most  brachytherapy  seed  designs,  and  this  uniformity  may  result in  better radiation  dose  coverage 
and  improved  therapeutic  effectiveness.    The  higher  energy  of  Cs-131  makes  the  isotope  more 
―forgiving‖ for treatment planning purposes.  IsoRay has conducted extensive computer modeling of its 
Proxcelan Cs-131 seed design.  The dosimetric characteristics of the Cs-131 seed were recently confirmed 
through  American  Association of  Physicists  in Medicine (AAPM) evaluations  of  the  seed  design  (Med 
Phys, 34:2).  The results of these tests showed superior dose characteristics relative to the leading I-125 
and  Pd-103  seeds.    The  IsoRay  seed  has  also  met  all  Nuclear  Regulatory  Commission  (NRC) 
requirements for sealed radioactive sources. 

Cs-131 Manufacturing Process and Suppliers 

Product Overview. Cs-131 is a radioactive isotope that can be produced by the neutron bombardment of 
Barium-130  (Ba-130).    When  placed  into  a  nuclear  reactor  and  exposed  to  a  flux  of  neutrons,  Ba-130 
becomes Ba-131, the radioactive material that is the parent  isotope  of Cs-131.  The radioactive isotope 
Cs-131  is  normally  produced  by  placing  a  quantity  of  stable  non-radioactive  barium  (ideally  barium 
enriched in isotope Ba-130) into the neutron flux of a nuclear reactor.  The irradiation process converts a 
small fraction of this material into a radioactive form of barium (Ba-131).  The Ba-131 decays by electron 
capture to the radioactive isotope of interest (Cs-131). 

To produce the Proxcelan seed, the purified Cs-131 isotope is adsorbed onto a ceramic core containing a 
gold  X-ray  marker.  This  internal  core  assembly  is  subsequently  inserted  into  a  titanium  capsule  that  is 
then  welded  shut  and  becomes  a  sealed  radioactive  source  and  a  biocompatible  medical  device.  The 
dimensional tolerances for the ceramic core, gold X-ray marker, and the titanium capsule are extremely 
important.  To date the Company has used sole-source providers for certain components such as the gold 
X-ray marker and the titanium capsule as these suppliers have been validated by our quality department 
and they have been cost effective. 

Barium  Enrichment  Device.    The  Company  has  retained  an  independent  contractor  to  develop  an 
enrichment device to produce ―enriched barium‖ having a higher concentration of the Ba-130 isotope than 
is found in naturally occurring barium.  Irradiating enriched barium will result in higher yields of Cs-131.  
The Company anticipates the use of enriched barium will also streamline the manufacturing process and 
reduce Cs-131 production costs.  The Company‘s prototype enrichment device is expected to be tested in 
October  2008  but  there  is  no  assurance  this  testing  will  occur  by  then  or  whether  or  not  it  will  be 
successful. 

Isotope Suppliers.  Due to the short half-life of both the Ba-131 and Cs-131 isotopes, potential suppliers 
must be capable of removing irradiated materials from the reactor core on a routine basis for subsequent 
processing  to  produce  ultra-pure  Cs-131.    In  addition,  the  supplier‘s  nuclear  reactor  facility  must  have 
sufficient  irradiation  capacity  to  accommodate  barium  targets  and  the  nuclear  reactors  must  have 
sufficient  neutron  flux to  economically  produce  commercially  viable  quantities  of  Cs-131.    Ideally,  the 
irradiation  facility  will  also  have  a  radiochemical  separation  infrastructure  to  carry  out  the  initial 
separation  steps.    The  Company  has  identified  key  reactor  facilities  in  the  U.S.  and  the  former  Soviet 
Union  that  are  capable  of  meeting  these  requirements.    As  of  the  date  of  this  report,  IsoRay  has 
agreements in place with three suppliers of irradiated Ba-131 or Cs-131.  For the fiscal year ended June 
30,  2008,  approximately  sixty-five  percent  (65%)  of  our  Cs-131  was  supplied  by  one  of  two  Russian 
suppliers, but the Company has begun taking steps to reduce its reliance on a single source for Cs-131. 

With  the  development  of  barium  enrichment  capabilities,  the  Company  plans  to  expand  Cs-131 
manufacturing  capability  at  the  MURR  reactor  in  the  United  States  but  will  continue  to  obtain  Cs-131 
from  multiple  suppliers.    Failure  to  obtain  deliveries  of  Cs-131  from  multiple  sources  could  have  a 
material  adverse  effect  on  seed  production.    Management  believes  it  will  continue  to  rely  solely  on  its 
three suppliers in the near future and shutdowns from these suppliers could cause delays in deliveries and 
production. 

11 

 
 
 
 
 
 
 
 
Quality  Controls.    We  have  established  procedures  and  controls  to  comply  with  the  FDA‘s  Quality 
System Regulation.  The Company constantly monitors these procedures and controls to ensure that they 
are operating properly, thereby working to maintain a high-quality product.  Also, the quality, production, 
and  customer  service  departments  maintain  open  communications  to  ensure  that  all  regulatory 
requirements for the FDA, DOT, and applicable nuclear radiation and health authorities are fulfilled. 

In  July  2008,  IsoRay  had  its  baseline  inspection  by  the  FDA  at  its  manufacturing  and  administrative 
offices in Richland, WA.  This inspection was carried out over a five day period of time during which the 
investigator performed an inspection following Quality Systems Inspection Techniques (QSIT).  This was 
a complete and very thorough inspection.  At the end of the inspection no report of deviations from Good 
Manufacturing Practices or list of observations (form FDA 483) was issued to IsoRay. 

Order Processing.  The Company has implemented a just-in-time production process that is responsive to 
customer input and orders to ensure that individual customers receive a higher level of customer service 
than  received  from  our  competitors  who  have  the  luxury  of  longer  lead  times  due  to  longer  half-life 
products.    Time  from  order  confirmation  to  completion  of  product  manufacture  is  reduced  to  several 
working  days,  including  receipt  of  irradiated  barium  (from  a  supplier‘s  reactor),  separation  of  Cs-131, 
isotope  labeling  of  the  core,  and  loading  of  cores  into  pre-welded  titanium  ―cans‖  for  final  welding, 
testing, quality assurance and shipping. 

It  is  up  to  each  physician  to  determine  the  dosage  necessary  for  implants  and  acceptable  dosages  vary 
among  physicians.    Many  of  the  physicians  who  order  our  seeds  order  more  seeds  than  necessary  to 
assure  themselves  that  they  have  a  sufficient  quantity.    Upon  receipt  of  an  order,  the  Company  either 
delivers  the  seeds  from  its  facility  directly  to  the  physician  or  sends  the  order  to  an  independent 
preloading service that delivers the seeds preloaded into needles or cartridges just prior to implant.  If the 
implant is postponed or rescheduled, the short half-life of the seeds makes them unsuitable for use and 
therefore they must be re-ordered.   

Due to the lead time for obtaining and processing the Cs-131 isotope and the short half-life, the Company 
relies  on  sales  forecasts  and  historical  knowledge  to  estimate  the  proper  inventory  levels  of  isotope 
needed to fulfill all customer orders.  Consequently, some portion of the isotope is lost through decay and 
is not used in an end product.  Management continues to reduce the variances between ordered isotope 
and isotope deliveries and is continually improving its ordering process efficiencies. 

Automated Manufacturing Process 

Based on evaluations of automation options by management, IsoRay has elected to automate its current 
manufacturing process in phases.  Phased implementation of automation is expected to be less costly than 
fully automated production lines and will benefit IsoRay by reducing labor costs and ensuring consistent 
manufacturing  quality.    The  Company  has  purchased  some  automation  equipment  and  is  reviewing 
options for the development of additional automated equipment.  The Company also has a contract with a 
third party to outsource certain sub-processes.  

Manufacturing Facility 

The  Company  has  replaced  its  original  manufacturing  facility  located  at  PEcoS-IsoRay  Radioisotope 
Laboratory (PIRL) with a production facility located at Applied Process Engineering Laboratory (APEL).  
The  APEL  facility  became  operational  in  September  2007,  which  was  three  months  earlier  than  the 
original  scheduled  opening.    The  facility  has  over  15,000  square  feet  and  includes  space  for  isotope 
separation,  seed  production,  order  dispensing,  a  clean  room  for  radiopharmacy  work,  and  a  dedicated 
shipping area.  A description of the lease terms for the APEL facility is located in the Other Commitments 
and Contingencies section of Item 7 below.  Management believes that the APEL facility will be utilized 
for manufacturing space through fiscal year 2016 which is the original lease term plus the two three-year 
renewal options.  Management currently anticipates exercising both three-year renewal options to extend 
the APEL facility lease through April 2016.

Isotope Testing in Idaho 

On December 14, 2005, IsoRay and Idaho‘s Advanced Test Reactor (ATR) entered into a collaboration 
and  partnership  agreement  for  the  design,  analysis  and  fabrication  of  a  capsule  containing  barium 
carbonate, to be irradiated at the ATR and then shipped to IsoRay for processing and analysis of the Cs-
131 product.  As an adjunct to this testing, IsoRay and the Pocatello Development Authority entered into 
an  Economic  Development  Agreement,  dated  December  14,  2005,  under  which  the  Pocatello 
Development Authority provided IsoRay with $200,000 (subject to repayment under certain conditions) 
to apply to the cost of testing at the ATR.  ATR is currently working to install a shuttle system that would 
make  the  production  of  Cs-131  possible  in  the  reactor.    There  is  no  assurance  that  even  though  the 
capsules irradiated in 2006 performed as designed that the shuttle system will provide adequate conditions 
for Cs-131 production.  The Company has no agreement with ATR to either produce Cs-131 or irradiate 
Ba-130 and there is no assurance that this will ultimately occur. 

Repackaging Services 

Most  brachytherapy  manufacturers  offer  their  seed  product  to  the  end  user  packaged  in  four  principal 
configurations provided in a sterile or non-sterile package depending on the customer‘s preference.  These 
include: 

  Loose seeds 
  Pre-loaded needles (loaded typically with three to five seeds and spacers) 
  Strands of seeds (consists of seeds and spacers in a biocompatible ―shrink wrap‖)  
  Pre-loaded Mick cartridges (fits the Mick applicator) 

In  2008,  the  Millenium  Research  Group  reported  that  the  estimated  market  shares  for  each  of  the  four 
packaging types are: loose seeds and preloaded loose seeds (8%), Mick cartridges (26%), and all strand 
configurations including preloaded strands (66%).  Market trends indicate significant movement toward 
the stranded configuration, as there are some clinical data suggesting less potential for post-implant seed 
migration when a stranded configuration is used. 

The  role  of  the  preloading  service  is  to  package,  assay  and  certify  the  contents  of  the  final  product 
configuration  shipped  to  the  customer.    A  commonly  used  method  of  providing  this  service  is  through 
independent radiopharmacies.  Manufacturers send loose seeds along with the physician's instructions to 
the  radiopharmacy  which,  in  turn,  loads  needles  and/or  strands  the  seeds  according  to  the  doctor's 
instructions.    These  radiopharmacies  then  sterilize  the  product  and  certify  the  final  packaging  prior  to 
shipping directly to the end user. 

IsoRay currently has agreements with several independent radiopharmacies to assay, preload, and sterilize 
loose  seeds.   This creates additional  loss of our isotope  due  to  decay  and is prohibitive  on  a  long-term 
basis.    While  the  Company  pre-loads  many  of  its  current  orders,  we  have  continued  to  utilize  these 
services to supplement our own custom preloading operation and when they are requested by the ordering 
physician. 

We  currently  load  most  Mick  cartridges  in  our  own  facility  which  in  recent  months  accounted  for 
approximately  53%  of  total  orders.    The  remaining  approximately  47%  of  total  orders  are  strand 
configurations including preloaded strands.  During fiscal year 2008, the Company began offering a 100% 
confirmation  assay  performed  by  in-house  analytical  services.    Providing  the  assay  and  ultimately  the 
preloading services in-house allows the Company to eliminate approximately 25% loss in isotope activity 
due to radioactive decay.  The cost of priority overnight shipment of each order of seeds to a third-party 
provider  is  also  eliminated.    However,  we  will  continue  to  utilize  the  independent  radiopharmacies  to 
back  up  our  own  preloading  operation,  to  handle  periodic  increases  in  demand,  and  to  cater  to  certain 
doctor‘s preferences. 

13 

 
 
 
 
 
 
 
 
 
 
 
Independent radiopharmacies usually provide the final packaging of the product delivered to the end user 
thereby eliminating the opportunity for reinforcing the "branding" of our seed product.  By providing our 
own repackaging service, we will preserve the product branding opportunity and eliminate any concerns 
related to the handling of our product by a third party prior to delivery to the end user. 

Providing custom packaging configurations enhances our product while providing an additional revenue 
stream  and  incremental  margins  to  the  Company  through  pricing  premiums  charged  to  our  customers.  
The end users of these packaging options are willing to pay a premium because of the savings they realize 
by eliminating the need for loose seed handling and loading capabilities on site, eliminating the need for 
additional staffing to sterilize seeds and needles, and eliminating the expense of additional assaying of the 
seeds. 

Marketing and Sales 

Marketing Strategy 

The  Company  is  marketing  Proxcelan  Cesium-131  brachytherapy  seeds  as  the  ―seed  of  choice‖  for 
prostate brachytherapy.  Based on current and preliminary clinical studies, management believes there is 
no  apparent  clinical  reason  to  use  other  isotopes  when  Cs-131  is  available.   The  advantages  associated 
with a  higher  energy  and  shorter  half-life isotope  are generally  accepted  within  the  clinical  community 
and  the  Company  intends  to  help educate  potential  patients about  the  clinical  benefits from  Cs-131  for 
their brachytherapy seed treatment. 

IsoRay has chosen to identify its proprietary Cs-131 seed with the brand of ―Proxcelan.‖  Management is 
using this brand to differentiate Cs-131 seeds from seeds using the other isotopes.  We continue to target 
the  competing  isotope  products  of  iodine  and  palladium  rather  than  the  various  manufacturers  and 
distributors  of  these  isotopes.    Using  this  strategy,  the  choice  of  brachytherapy  isotopes  should  be  less 
dependent on the name and distribution strengths of the various iodine and palladium manufacturers and 
distributors and more dependent on the therapeutic benefits of Cs-131. 

The professional and patient market segments each play a role in the ultimate choice of cancer treatment 
and  the  specific  isotope  chosen  for  seed  brachytherapy  treatment.    The  Company  has  developed  a 
customized  brand  message  for  each  audience.    For  medical  professionals,  IsoRay  has  created  print  and 
visual  medias  (including  physician  brochures  discussing  the  clinical  advantages  of  Cs-131,  clinical 
information  binders,  informational  DVDs,  single  sheet  glossies  with  targeted  clinical  data,  etc.), 
advertisements  in  the  leading  medical  journals  and  a  physician  targeted  website.    In  addition,  the 
Company attends national professional meetings, including the following: 

  American Brachytherapy Society (ABS), 
  American Society for Therapeutic Radiation and Oncology (ASTRO), and 
  Association of American Physicists in Medicine (AAPM). 

The Company also continues to consult with noted contributors from the medical physics community and 
will have articles submitted to professional journals such as Medical Physics, the Brachytherapy Journal, 
and the International Journal of Radiation Oncology, Biology, and Physics regarding the benefits of and 
clinical trials involving Cs-131. 

Beginning  in  January  2008,  IsoRay  implemented  a  variety  of  physician  Cs-131  training  outreach 
programs including the following:  a two day training course held approximately three times per year at 
Chicago  Prostate  Cancer  Center  (CPCC);  proctoring  and  mentoring  programs  led  by  Steve  Kurtzman, 
MD,  IsoRay‘s  Medical  Director;  and  a  training  DVD  for  physicians  who  choose  not  to  leave  their 
practices to attend a training course. 

The objective of the training programs is to increase the physician‘s confidence in using the product.  To 
track the impact of the courses held in January 2008 and in May 2008, IsoRay has compared physicians‘ 
average monthly order activity for the six month periods prior to and after attending the course.  To date 

14 

 
 
 
 
 
 
 
 
 
 
there has been a 42% increase in average monthly order activity when comparing these two time periods 
for those physicians participating in the January and May training courses. 

In today‘s U.S. health care market, patients are more informed and involved in the management of their 
health than in the past.  Many physicians relate incidents of their patients coming for consultations armed 
with articles researched on the Internet and other sources describing new treatments and medications.  In 
many  cases,  these  patients  are  demanding  a  certain  therapy  or  drug  and  the  physicians  are  complying 
when medically appropriate. 

Because  of  this  consumer-driven  market  factor,  we  also  promote  our  products  directly  to  the  general 
public.  We target the prostate cancer patient, his spouse, family and care givers.  We emphasize to these 
segments the specific advantages of the Proxcelan Cesium-131 brachytherapy seed through our websites 
(located  at  www.isoray.com,  www.cesium.com,  and  www.proxcelan.com),  patient  advocacy  efforts, 
informational  patient  brochures  and  DVDs  with  patient  testimonials,  patient  focused  informational 
website (www.proxcelan.com), and advertisements in specific markets supporting brachytherapy.  None 
of the websites mentioned in the preceding sentence are part of this report. 

In  addition,  the  Company  continues  to  promote  the  clinical  findings  of  the  various  protocols  through 
presentations  by  respected  thought  leaders.    The  Company  will  continually  review  and  update  all 
marketing materials as more clinical information is gathered from the protocols and studies. 

Apart from clinical studies and papers sponsored by the Company, several physicians across the country 
are now independently publishing papers and studies extolling the benefits of Cs-131. 

Sales and Distribution 

According  to  a  recent  industry  survey,  approximately  2,000  hospitals  and  free  standing  clinics  are 
currently offering radiation oncology services in the United States.   Not all of these facilities offer seed 
brachytherapy services.  These institutions are staffed with radiation oncologists and medical physicists 
who provide expertise in radiation therapy treatments and serve as consultants for urologists and prostate 
cancer patients.  We target the radiation oncologists and the medical physicists as well as urologists as 
key clinical decision-makers in the type of radiation therapy offered to prostate cancer patients. 

IsoRay  has  a  direct  sales  organization  to  introduce  Proxcelan  Cesium-131  brachytherapy  seeds  to 
radiation oncologists and medical physicists.  Currently IsoRay has six direct sales persons and a National 
Sales  Director.    These  sales  people  include  those  experienced  in  the  brachytherapy  market  and  the 
medical  device  market.    IsoRay  is  evaluating  all  options  for  distribution  of  the  Proxcelan  Cesium-131 
seed and may in the future add additional distribution channels. 

With  the  restructuring  of  the  compensation  structure  by  new  management,  the  Company  lost  several 
members of its sales force who did not want to rely on a reduced base salary and increased commissions 
approach.    From  the  date  of  the  changes  in  compensation  structure  until  September  22,  2008,  the 
Company has lost four sales representatives and replaced them with four new sales representatives.  As 
management increasingly focuses on improving sales, additional changes may be necessary. 

The Company expects to continue to expand its customer base in fiscal year 2009.  When the Company 
implements its plans to expand outside the U.S. market, it plans to use established distributors in the key 
markets in these other countries.  This strategy should reduce the time and expenses required to identify, 
train  and  penetrate  the  key  implant  centers  and  establish  relationships  with  the  key  opinion  leaders  in 
these  markets.    Using  established  distributors  also  should  reduce  the  time  spent  acquiring  the  proper 
radiation handling licenses and other regulatory requirements of these markets.

Reimbursement 

Payment  for  IsoRay  products  comes  from  third-party  payers  including  the  Centers  for  Medicare  and 
Medicaid  Services  (CMS)  and  private  insurance  companies.    These  payers  reimburse  the  hospitals  and 
clinics  via  well-established  payment  procedures.    In  2003,  the  Company  was  approved  for  an  initial 
HCPCS  code  for  Cs-131  brachytherapy  seeds.    In  July  2007  CMS  divided  the  HCPCS  code  into  two 
codes for all manufacturers of brachytherapy seeds.  The current method has assigned one HCPCS code 
for loose seeds and a second HCPCS code for stranded seeds.  Medicare is the most significant U.S. payer 
for  prostate  brachytherapy  services,  and  is  the  payer  in  approximately  65%  of  all  U.S.  prostate 
brachytherapy cases. 

Prostate brachytherapy is typically performed in an outpatient setting, and as such, is covered by the CMS 
Outpatient Prospective Payment System.  Currently, when charges for the seeds are correctly submitted to 
CMS, the total cost of the seeds is reimbursed to the hospital or clinic by CMS.  CMS had proposed that a 
fixed price per seed be reimbursed; however, Congress (after postponing a decision on the Medical Bill 
which included brachytherapy seed reimbursement) voted on July 15, 2008 to continue the pass-through 
reimbursement  for  brachytherapy  seeds  through  December  31,  2009.    Other  insurance  companies  have 
historically followed CMS‘s reimbursement policies. 

Other Information 

Customers 

Customers representing ten percent or more of total Company sales for the twelve months ended June 30, 
2008 include: 

Various Northern California facilities (a) 
Chicago Prostate Cancer Center 

Westmont, IL 

18.6% of revenue 
15.7% of revenue  

(a)  The following facilities located in northern California are used by one doctor (the Company‘s 
Medical  Director):    Community  Hospital  of  Los  Gatos  (11.0%  of  total  revenue),  Mills 
Peninsula Health Services (4.3%), and all others used by this doctor combined (3.3%). 

The loss of any of these significant customers would have an adverse effect on the Company‘s revenues, 
which would continue until the Company located new customers to replace them. 

Proprietary Rights 

The  Company  relies  on  a  combination  of  patent,  copyright  and  trademark  laws,  trade  secrets,  software 
security  measures,  license  agreements  and  nondisclosure  agreements  to  protect  its  proprietary  rights.  
Some of the Company‘s proprietary information may not be patentable. 

The  Company  intends  to  vigorously  defend  its  proprietary  technologies,  trademarks,  and  trade  secrets.  
Members of management, employees, and certain equity holders have previously signed non-disclosure, 
non-compete agreements, and future employees, consultants, advisors, with whom the Company engages, 
and who are privy to this information, will be required to do the same.  A patent for the cesium separation 
and purification process was granted on May 23, 2000 by the U.S. Patent and Trademark Office (USPTO) 
under Patent Number 6,066,302, with an expiration date of May 23, 2020.  The process was developed by 
Lane  Bray,  Chief  Chemist  and  a  shareholder  of  the  Company,  and  has  been  assigned  exclusively  to 
IsoRay.  IsoRay‘s predecessor also filed for patent protection in four European countries under the Patent 
Cooperation Treaty.  Those patents have been assigned to IsoRay. 

Our management believes that certain aspects of the IsoRay seed design and construction techniques are 
patentable  innovations.    These  innovations  have  been  documented  in  IsoRay  laboratory  records,  and  a 
patent application was filed with the USPTO on November 12, 2003.  In August 2008, this patent was 

16 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
granted by the USPTO under Patent Number 7,410,458, with an expiration date of November 12, 2023.  
Certain  methodologies  regarding  isotope  production,  separation,  and  seed  manufacture  are  retained  as 
trade secrets and are embodied in IsoRay‘s procedures and documentation.  In June 2004, July 2004, and 
February 2007, five patent applications were filed relating to methods of deriving Cs-131 developed by 
IsoRay employees.  The Company is currently working on developing and patenting additional methods 
of deriving Cs-131 and other isotopes. 

There  are  specific  conditions  attached  to  the  assignment  of  the  Cs-131  patent  from  Lane  Bray.    In 
particular, the associated Royalty Agreement provides for 1% of gross profit payment from seed sales to 
Lane Bray and 1% of gross profit from any use of the Cs-131 process patent for non-seed products.  If 
IsoRay  reassigns  the  Royalty  Agreement  to  another  company,  these  royalties  increase  to  2%.    The 
Royalty  Agreement  has  an  anti-shelving  clause  which  requires  IsoRay  to  return  the  patent  if  IsoRay 
permanently  abandons  sales  of  products  using  the  invention.    During  fiscal  years  2008  and  2007,  the 
Company recorded royalty expense of $21,219 and $2,161, respectively, related to this patent. 

The  terms  of  a  license  agreement  with  the  Lawrence  Family  Trust  (successor  to  Don  Lawrence)  for  a 
patent  application  and  related  ―know-how‖  require  the  payment  of  a  royalty  based  on  the  Net  Factory 
Sales  Price,  as  defined  in  the  agreement,  of  licensed  product  sales.    Because  the  licensor‘s  patent 
application  was  ultimately  abandoned,  only  a  1%  ―know-how‖  royalty  remains  applicable.  To  date, 
management believes that there have been no product sales incorporating the ―know-how;‖ and therefore 
believes no royalty is due pursuant to the terms of the agreement.  Management believes that ultimately 
no royalties should be paid under this agreement as there is no intent to use this ―know-how‖ in the future. 

The Lawrence Family Trust has disputed management‘s contention that it is not using this ―know-how‖.  
On  September  25,  2007  and  again  on  October  31,  2007,  the  Company  participated  in  nonbinding 
mediation  regarding  this  matter;  however,  no  settlement  was  reached  with  the  Lawrence  Family  Trust.  
After  additional  settlement  discussions,  which  ended  in  April  2008,  the  parties  failed  to  reach  a 
settlement.  The parties may demand binding arbitration at any time. 

The  Company‘s  Proxcelan  trademark  has  been  preliminarily  approved  and  the  Company  is  currently 
waiting for the final approval letter from the USPTO. 

Research and Development 

During the three-year period ended June 30, 2008, IsoRay and its predecessor companies incurred more 
than  $3.2  million  in  costs  related  to  research  and  development  activities.    The  Company  expects  to 
continue ongoing research and development activities for the foreseeable future. 

Whether successful or not, the Company anticipates ending its major research and development project to 
develop a proprietary separation process to manufacture enriched barium during fiscal year 2009.  During 
fiscal year 2008, the Company spent approximately $483,000 on this project.  The remaining project costs 
are anticipated to be approximately $150,000. 

Government Regulation 

The Company's present and future intended activities in the development, manufacture and sale of cancer 
therapy products are subject to extensive laws, regulations, regulatory approvals and guidelines.  Within 
the  United  States,  the  Company's  therapeutic  radiological  devices  must  comply  with  the  U.S.  Federal 
Food, Drug and Cosmetic Act, which is enforced by the FDA.  The Company is also required to adhere to 
applicable  FDA  Quality  System  Regulations,  also  known  as  the  Good  Manufacturing  Practices,  which 
include  extensive  record  keeping  and  periodic  inspections  of  manufacturing  facilities.    The  Company's 
predecessor obtained FDA 510(k) clearance in March 2003 to market the Proxcelan Cs-131 seed for the 
treatment  of  localized  solid  tumors  and  other  malignant  disease  and  IsoRay  obtained  FDA  510(k) 
clearance in November 2006 to market preloaded brachytherapy seeds. 

17 

 
 
 
 
 
 
 
 
 
 
 
In  the  United  States,  the  FDA  regulates,  among  other  things,  new  product  clearances  and  approvals  to 
establish the safety and efficacy of these products.  We are also subject to other federal and state laws and 
regulations, including the Occupational Safety and Health Act and the Environmental Protection Act. 

The Federal Food, Drug, and Cosmetic Act and other federal statutes and regulations govern or influence 
the  research,  testing,  manufacture,  safety,  labeling,  storage,  record  keeping,  approval,  distribution,  use, 
reporting, advertising and promotion of such products.  Noncompliance with applicable requirements can 
result in civil penalties, recall, injunction or seizure of products, refusal of the government to approve or 
clear  product  approval  applications,  disqualification  from  sponsoring  or  conducting  clinical 
investigations,  preventing  us  from  entering  into  government  supply  contracts,  withdrawal  of  previously 
approved applications, and criminal prosecution. 

In  the  United  States,  medical  devices  are  classified  into  three  different  categories  over  which  the  FDA 
applies increasing levels of regulation: Class I, Class II, and Class III.  Most Class I devices are exempt 
from premarket notification (510(k)); most Class II devices require premarket notification (510(k)); and 
most Class III devices require premarket approval.  Our Proxcelan Cs-131 seed is a Class II device and 
received 510(k) clearance in March 2003. 

Approval  of  new  Class  III  medical  devices is a  lengthy  procedure  and  can  take  a  number  of  years and 
require the expenditure of significant resources.  There is a shorter FDA review and clearance process for 
Class II  medical devices, the premarket notification or 510(k) process, whereby a company can  market 
certain Class II medical devices that can be shown to be substantially equivalent to other legally marketed 
devices.  Since brachytherapy seeds have been classified by the FDA as a Class II device, we have been 
able to achieve market clearance for our Cs-131 seed using the 510(k) process. 

As  a  registered  medical  device  manufacturer  with  the  FDA,  we  are  subject  to  inspection  to  ensure 
compliance  with their  current  Good Manufacturing  Practices,  or  cGMP.   These regulations require that 
we  and  any  of  our  contract  manufacturers  design,  manufacture  and  service  products,  and  maintain 
documents  in  a  prescribed  manner  with  respect  to  manufacturing,  testing,  distribution,  storage,  design 
control, and service activities.  Modifications or enhancements that could significantly affect the safety or 
effectiveness of a device or that constitute a major change to the intended use of the device require a new 
510(k) notice for any product modification. 

The Medical Device Reporting regulation requires that we provide information to the FDA on deaths or 
serious injuries alleged to be associated with the use of our devices, as well as product malfunctions that 
are likely to cause or contribute to death or serious injury if the malfunction were to recur.  Labeling and 
promotional  activities  are  regulated  by  the  FDA  and,  in  some  circumstances,  by  the  Federal  Trade 
Commission. 

As  a  medical  device  manufacturer,  we  are  also  subject  to  laws  and  regulations  administered  by 
governmental  entities  at  the  federal,  state  and  local  levels.    For  example,  our  facility  is  licensed  as  a 
medical  product  manufacturing  facility  in  the  State  of  Washington  and  is  subject  to  periodic  state 
regulatory  inspections.    Our  customers  are  also  subject  to  a  wide  variety  of  laws  and  regulations  that 
could affect the nature and scope of their relationships with us. 

In support of IsoRay‘s global strategy to expand marketing to Canada and Russia, as well as other foreign 
markets,  we  initiated  the  process  in  fiscal  year  2008  to  obtain  the  European  CE  Mark,  Canadian 
registration, and certification to ISO 13485, an internationally recognized quality system.  European law 
requires  that  medical  devices  sold  in  any  EU  Member  State  comply  with  the  requirements  of  the 
European  Medical  Device  Directive  (MDD)  or  the  Active  Implantable  Medical  Device  Directive 
(AIMDD).    IsoRay‘s  products  are  classified  in  Europe  as  an  active  implantable  and  are  subject  to  the 
AIMDD.  Compliance with AIMDD and obtaining a CE Mark involves being certified to ISO 13485 and 
obtaining  approval  of  the  product  technical  file  by  a  notified  body  that  is  recognized  by  competent 
authorities of a Member State.  Compliance with ISO 13485 is also required for registration of a company 
for sale of its products in Canada.  Many of the recognized EU Notified Bodies are also recognized by 

18 

 
 
 
 
 
 
 
 
Health  Canada  to  conduct  the  ISO  13485  inspections  for  Canadian  registration.    In  August  2008,  the 
Company received its certification to ISO 13485 and is continuing to seek Canadian registration and the 
European  CE  Mark.    The  Company  is  now  focusing  on  the  Canadian  and  Russian  markets  and  is  no 
longer pursuing sales in the European Union (EU).  Management does not believe a strategic alliance with 
IBt,  SA,  a  Belgian  company,  will  be  consummated  nor  will  management  leverage  IBt‘s  distribution 
channels in the EU. 

In  the  United  States,  as  a  manufacturer  of  medical  devices  and  devices  utilizing  radioactive  byproduct 
material, we are subject to extensive regulation by not only federal governmental authorities, such as the 
FDA, but also by state and local governmental authorities, such as the Washington State Department of 
Health, to ensure such devices are safe and effective.  In Washington State, the Department of Health, by 
agreement  with  the  federal  Nuclear  Regulatory  Commission  (NRC),  regulates  the  possession,  use,  and 
disposal  of  radioactive  byproduct  material  as  well  as  the  manufacture  of  radioactive  sealed  sources  to 
ensure  compliance  with  state  and  federal  laws  and  regulations.    Our  Cs-131  brachytherapy  seeds 
constitute both medical devices and radioactive sealed sources and are subject to these regulations. 

Moreover, our use, management, and disposal of certain radioactive substances and wastes are subject to 
regulation  by  several  federal  and  state  agencies  depending  on  the  nature  of  the  substance  or  waste 
material.  We believe that we are in compliance with all federal and state regulations for this purpose. 

Washington voters approved Initiative 297 in late 2004, which may impose additional restrictions on sites 
at  which  mixed  radioactive  and  hazardous  wastes  are  generated  and  stored,  as  it  prohibits  additional 
mixed  radioactive  and  hazardous  waste  from  being  brought  to  sites  until  the  existing  on-site  waste 
conforms to all state and federal environment laws.  In June 2006, a U.S. District court judge ruled that 
Initiative 297 was unconstitutional in its entirety and the Ninth Circuit upheld this decision in May 2008.  
However, the State of Washington may choose to appeal the decision.  If this decision is overturned and 
Initiative 297 is enforced it could impact our ability to manufacture our seeds in the State of Washington. 

Seasonality 

The Company believes that some seed implantation procedures are deferred around physician vacations 
(particularly  in  the  summer  months),  holidays,  and  medical  conventions  and  conferences  resulting  in  a 
seasonal  influence  on  the  Company‘s  business.    These  factors  cause  a  momentary  decline  in  revenue 
which  management  believes  is  ultimately  realized  later.    Because  almost  thirty  percent  (30%)  of  the 
Company's  business  relies  on  three  physicians,  simultaneous  vacations  by  these  three  physicians  could 
cause significant drops in the Company's productivity during those periods. 

Employees 

As of September 12, 2008, IsoRay employed 49 full-time individuals and one part-time individual.  The 
Company's  future  success  will  depend,  in  part,  on  its  ability  to  attract,  retain,  and  motivate  highly 
qualified  sales,  technical  and  management  personnel.    From  time  to  time,  the  Company  may  employ 
independent  consultants  or  contractors  to  support  its  research  and  development,  marketing,  sales,  and 
administrative  organizations.    None  of  the  Company's  employees  are  represented  by  any  collective 
bargaining unit.  IsoRay estimates that successful implementation of its growth plan would result in up to 
five to seven additional employees by the end of fiscal year 2009.  The significant decrease in anticipated 
employees from those projected in fiscal year 2008 is a result of the greater manufacturing efficiencies 
realized by the Company and lower than anticipated sales growth. 

Competition 

The Company competes in a market characterized by technological innovation, extensive research efforts, 
and  significant  competition.    In  general,  the  Proxcelan  Cesium-131  brachytherapy  seed  competes  with 
conventional  methods  of  treating  localized  cancer,  including,  but  not  limited  to,  all  forms  of 
prostatectomy surgery and external beam radiation therapy which includes intensity modulated radiation 

19 

 
  
 
 
 
 
 
 
 
 
therapy, as well as competing permanent brachytherapy devices.  Surgery has historically represented the 
most  common  medical  treatment  for  early-stage,  localized  prostate  cancer  but  radical  prostatectomies 
have  declined  in  recent  years.    EBRT  is  also  a  well-established  method  of  treatment  and  is  widely 
accepted for patients who represent a poor surgical risk or whose prostate cancer has advanced beyond the 
stage  for  which  surgical  treatment  is  indicated.    Management  believes  that  if  general  conversion  from 
these  treatment  options  (or  other  established  or  conventional  procedures)  to  the  Proxcelan  Cesium-131 
brachytherapy seed does occur, such conversion will likely be the result of a combination of equivalent or 
better  efficacy,  reduced  incidence  and  duration  of  side  effects  and  complications,  lower  cost,  better 
quality of life outcomes, and pressure by health care providers and patients. 

History has shown the advantage of being the first to market a new brachytherapy product.  For example, 
Theragenics Corp., which introduced the original Pd-103 seed, currently claims over 59% of the Pd-103 
market share (through CR Bard, other distributors, and direct distribution).  Although factors other than 
being first to market contribute to becoming a market leader, the Company believes it has the opportunity 
to  obtain  a  similar  and  significant  advantage  by  being  the  first  to  introduce  a  Cs-131  seed.    (Source:  
Millennium Research Corp, 2008) 

The  Company‘s  patented  Cs-131  separation  process  is  likely  to  provide  a  sustainable  competitive 
advantage.  Production of Cs-131 also requires specialized facilities that represent high cost and long lead 
time  if  not  readily  available.    In  addition,  a  competitor  would  need  to  develop  a  method  for  isotope 
attachment and seed assembly, would need to conduct testing to meet NRC and FDA requirements, and 
would need to obtain regulatory clearances before marketing a competing device. 

Several companies have obtained regulatory clearance to produce and distribute Pd-103 and I-125 seeds, 
which  compete  directly  with  our  seed.    Six  of  those  companies  represent  nearly  100%  of  annual 
brachytherapy  seed  sales  worldwide:  CR  Bard,  Inc  (32.3%),  Oncura  (21.7%)  (part  of  GE  Healthcare), 
Theragenics Corp (direct sales 9.5%), North American Scientific, Inc. (13.1%), Core Oncology (10.7%), 
and Best Medical International, Inc. (6.5%) (Source: Millennium Research Corp, 2008).   

It is possible that three or four of the current I-125 or Pd-103 seed manufacturers (e.g., CR Bard, Oncura, 
Theragenics, North American Scientific, etc.) are capable of producing and marketing a Cs-131 seed, but 
none  have reported  efforts  to  do so.    Best Medical  obtained a  seed  core patent in  1992  that  named  ten 
different isotopes, including Cs-131, for use in their seeds.  Best Medical received FDA 510(k) clearance 
to market a Cs-131 seed on June 6, 1993 but to date has not produced any products for sale.  In addition 
to  the  FDA  and  the  NRC,  Best  Medical  would  be  required  to submit  a  Cs-131  seed  to  the  TG-43  task 
group of the American Association of Physicists in Medicine to determine the seed‘s characteristics such 
as anisotropy, dose rate constant, etc.  To date there has been no submission to the TG-43 task group for a 
competing Cs-131 seed. 

Additional Growth Opportunities 

Management of the Company sees growth opportunities through expansion into international markets and 
additional treatment applicability to cancers other than prostate.  The Company plans to introduce Cs-131 
for prostate brachytherapy initially into Canada and Russia and later into Europe and other international 
markets  through  partnerships  and  strategic  alliances  with  channel  partners  for  manufacturing  and 
distribution. 

Cs-131  has  FDA  clearance  to  be  used  for  treatments  for  a  broad  spectrum  of  cancers  including  breast, 
brain,  lung,  and  liver  cancer,  and  the  Company  believes  that  a  major  opportunity  exists  as  an  adjunct 
therapy for the treatment of residual lung cancer and ocular melanoma.  The Company has already begun 
treating ocular melanoma.  The Company has had discussions with prominent physicians and is looking at 
treatment of lung and brain cancer. 

There is also an opportunity to develop and market other radioactive isotopes to the United States market, 
and  to  market  Cs-131  isotope  itself,  separate  from  its  use  in  our  seeds.    The  Company  is  also  in  the 

20 

 
 
 
 
 
 
 
 
 
preliminary stages of exploring alternate methods of delivering our isotopes to various organs of the body, 
as  it  may  be  advantageous  to  use  delivery  methods  other  than  a  titanium-encapsulated  seed  to  deliver 
radiation to certain organs. 

ITEM 1A – RISK FACTORS 

Our  Revenues  Depend  Upon  One  Product.    Until  such  time  as  we  develop  additional  products,  our 
revenues  depend  upon  the  successful  production,  marketing,  and  sales  of  the  Proxcelan  Cs-131 
brachytherapy seed.  The rate and level of market acceptance of this product may vary depending on the 
perception  by  physicians  and  other  members  of  the  healthcare  community  of  its  safety  and  efficacy  as 
compared  to  that  of  competing  products,  if  any;  the  clinical  outcomes  of  the  patients  treated;  the 
effectiveness of our sales and marketing efforts in the United States, Canada, and Russia; any unfavorable 
publicity  concerning  our  product  or  similar  products;  our  product‘s  price  relative  to  other  products  or 
competing  treatments;  any  decrease  in  current  reimbursement  rates  from  the  Centers  for  Medicare  and 
Medicaid Services or third-party payers; regulatory developments related to the manufacture or continued 
use of the product; availability of sufficient supplies of enriched barium (now coming from Russia) for 
Cs-131  seed  production;  ability  to  produce  sufficient  quantities  of  this  product;  and  the  ability  of 
physicians to properly utilize the device and avoid excessive levels of radiation to patients.   Because of 
our reliance on this product as the sole source of our revenue, any material adverse developments with 
respect  to  the  commercialization  of  this  product  may  cause  us  to  continue  to  incur  losses  rather  than 
profits in the future. 

Although  Cleared  To  Treat  Any  Malignant  Tissue,  Our  Sole  Product  Is  Currently  Used  To  Treat  Two 
Types Of Cancer.  Currently, the Proxcelan Cs-131 seed is used exclusively for the treatment of prostate 
cancer and ocular melanoma (less than one percent of our sales).  We believe the Proxcelan Cs-131 seed 
will be used to treat other types of cancers, as is currently the case with our competitors‘ I-125 and Pd-
103 seeds.  However, we believe that clinical data gathered by select groups of physicians under treatment 
protocols  specific  to  other  organs  will  be  needed  prior  to  widespread  acceptance  of  our  product  for 
treating other cancer sites.  If our current and future products do not become accepted in treating cancers 
of other sites, our sales will depend solely on treatment of prostate cancer and will require ever increasing 
market share to increase revenues. 

We Have Increasing Cash Requirements.  IsoRay has generated material operating losses since inception.  
We expect to continue to experience significant net operating losses.  Due to previous capital investments, 
management believes cash and cash equivalents on hand at June 30, 2008 will be sufficient to meet our 
anticipated cash requirements for operations, debt service, and capital expenditure requirements through 
at least the next twelve months.  If operating costs expand proportionately with revenue increases, other 
applications are pursued for seed usage outside the prostate market, if protocols are expanded to support 
the integrity of our product, and marketing expenses increase, management believes approximately $1.5 
million  in  monthly  revenue  will  be  needed  to  reach  break-even.    This  is  a  decrease  from  the  previous 
estimate  of  $2  million  in  monthly  revenue  due  to  recent  improvements  in  the  Company‘s  production 
operating  efficiencies  and  its  cost  structure  implemented  by  new  management.    However,  there  is  no 
assurance  as  to  when  break-even  will  occur.   If  we  are  unable  to  generate  profits  and  unable  to  obtain 
additional financing to meet our working capital requirements, we may have to curtail our business. 

We Rely Heavily On A Limited Number Of Suppliers.  Some materials used in our products are currently 
available only from a limited number of suppliers.  In fiscal 2008, approximately sixty-five percent (65%) 
of our cesium was supplied through either the Institute of Nuclear Materials (INM) or from the Russian 
Research Institute of Atomic Reactors (RIAR) both of which are located in Russia.  Beginning in January 
2008, we were unable to obtain any Cs-131 from INM and instead obtained all of our supply of Cs-131 in 
Russia from RIAR until August 2008, when RIAR was shut down for regularly scheduled maintenance 
and  we  resumed  purchasing  from  INM.    However,  beginning  in  October  2008,  we  will  obtain  Cs-131 
from  both  INM  and  RIAR.    At  current  production  levels  the  Company  cannot  meet  the  minimum 
purchase requirements necessary to purchase the product at the reduced prices presently offered.  Unless 
the  Company  substantially  increases  its  purchase  requirements  resulting  from  significant  increases  in 

21 

 
 
 
 
 
 
demand  for  its  product,  the  cost  of  Cs-131  in  Russia  could  significantly  increase  from  current  pricing.  
Management will seek to negotiate favorable pricing but there is no assurance as to the outcome of these 
negotiations. 

If the development of barium enrichment capabilities is successful, the Company plans to expand Cs-131 
manufacturing  capability  at  the  MURR  reactor  in  the  United  States.  Reliance  on  any  single  supplier 
increases the risks associated with concentrating isotope production at a single reactor facility which are 
subject  to  unanticipated  shutdowns.  Failure  to  obtain  deliveries  of  cesium  from  multiple  sources  could 
have  a  material  adverse  effect  on  seed  production  and  there  may  be  a  delay  before  we  could  locate 
alternative suppliers beyond the three currently used. 

We  may  not  be  able  to  locate  additional  suppliers  outside  of  Russia  capable  of  producing  the  level  of 
output of cesium at the quality standards we require. Additional factors that could cause interruptions or 
delays in our source of materials include limitations on the availability of raw materials or manufacturing 
performance experienced by our suppliers and a breakdown in our commercial relations with one or more 
suppliers. Some of these factors may be completely out of our and our suppliers‘ control.  

Virtually  all  titanium  tubing  used  in  brachytherapy  seed  manufacture  comes  from  a  single  source, 
Accellent  Corporation.    We  currently  obtain  a  key  component  of  our  seed  core  from  another  single 
supplier.    We  do  not  have  formal  written  agreements  with  Accellent  Corporation.    Any  interruption  or 
delay  in  the  supply  of  materials  required  to  produce  our  products  could  harm  our  business  if  we  were 
unable  to  obtain  an  alternative  supplier  or  substitute equivalent  materials  in  a  cost-effective  and timely 
manner.  To mitigate any potential interruptions, the Company continually evaluates its inventory levels 
and  management  believes  that  the  Company  maintains  a  sufficient  quantity  on  hand  to  alleviate  any 
potential disruptions. 

Future  Production  Increases  Will  Depend  on  Our  Ability  to  Acquire  Larger  Quantities  of  Cs-131  and 
Hire More Employees.  IsoRay currently obtains Cs-131 through its contracts with INM and RIAR, and 
through  reactor  irradiation  of  natural  barium  and  subsequent  separation  of  cesium  from  the  irradiated 
barium targets.  The amount of Cs-131 that can be produced from a given reactor source is limited by the 
power  level  and  volume  available  within  the  reactor  for  irradiating  targets.    This  limitation  can  be 
overcome  by  utilizing  barium  feedstock  that  is  enriched  in  the  stable  isotope  Ba-130.    However,  the 
number  of  suppliers  of  enriched  barium  is  limited  and  they  may  be  unable  to  produce  this  material  in 
sufficient quantities at a reasonable price. 

IsoRay  has  entered  into  exclusive  agreements  with  INM  and  RIAR  in  Russia  to  provide  Cs-131  in 
quantities sufficient to supply a significant percentage of future demand for this isotope.  Delivery of the 
isotope  from  INM  began  in  January  2006  and  delivery  from  RIAR  began  in  January  2008.    INM  has 
unique capabilities due to its large irradiation capacity which will allow the Company to meet all of its 
Cs-131 demands without the use of enriched material for the foreseeable future.  Due to the purchase of 
enriched barium in June 2007, IsoRay has access to sufficient quantities of enriched barium that may be 
recycled to increase the production of Cs-131.  Although the agreements provide for supplying Cs-131 in 
significant quantities, there is no assurance that this will result in IsoRay gaining access to a  continuing 
sufficient  supply  of  enriched  barium  feedstock.    If  we  were  unable  to  obtain  supplies  of  isotopes  from 
Russia in the future, our overall supply of cesium and barium would be reduced significantly unless the 
Company has a source of enriched barium for utilization in domestic reactors. 

We  Are  Subject  To  Uncertainties  Regarding  Reimbursement  For  Use  Of  Our  Products.    Hospitals  and 
freestanding  clinics  may  be  less  likely  to  purchase  our  products  if  they  cannot  be  assured  of  receiving 
favorable reimbursement for treatments using our products from third-party payers, such as Medicare and 
private health insurance plans.   Currently, Medicare reimburses hospitals, clinics and physicians for the 
cost of seeds used in brachytherapy procedures on a pass through basis, and will continue this method of 
reimbursement  through  December  31,  2009.    Historically,  private  insurers  have  followed  Medicare 
guidelines in establishing reimbursement rates.  However, third-party payers are increasingly challenging 
the  pricing  of  certain  medical  services  or  devices,  and  we  cannot  be  sure  that  they  will  reimburse  our 

22 

 
 
 
 
 
 
 
customers at levels sufficient for us to maintain favorable sales and price levels for our products.  There is 
no uniform policy on reimbursement among third-party payers, and we can provide no assurance that our 
products  will  continue  to  qualify  for  reimbursement  from  all  third-party  payers  or  that  reimbursement 
rates will not be reduced.  A reduction in or elimination of third-party reimbursement for treatments using 
our products would likely have a material adverse effect on our revenues. 

In  2003,  we  applied  to  the  Centers  for  Medicare  and  Medicaid  Services  (CMS)  and  received  a 
reimbursement code for use of our Cs-131 seed.  As of July 1, 2007, CMS revised the coding system for 
brachytherapy seeds and separated the single code into two codes – one code for loose seeds and a second 
code for stranded seeds.  This methodology was applied to all companies manufacturing and distributing 
brachytherapy seeds.  Reimbursement amounts are reviewed and revised annually.  Adjustments could be 
made  to  these  reimbursement  amounts  or  policies,  which  could  result  in  reduced  reimbursement  for 
brachytherapy services, which could negatively affect market demand for our products. 

Furthermore,  any  federal  and  state  efforts  to  reform  government  and  private  healthcare  insurance 
programs  could  significantly  affect  the  purchase  of  healthcare  services  and  products  in  general  and 
demand for our products in particular.  Medicare is the payer in approximately 70% of all U.S. prostate 
brachytherapy cases and management anticipates this percentage to increase annually.  We are unable to 
predict  whether  potential  healthcare  reforms  will  be  enacted,  whether  other  healthcare  legislation  or 
regulations  affecting  the  business  may  be  proposed  or  enacted  in  the  future  or  what  effect  any  such 
legislation or regulations would have on our business, financial condition or results of operations. 

Our  Operating  Results  Will  Be  Subject  To  Significant  Fluctuations.    Our  quarterly  revenues,  expenses, 
and  operating  results  are  likely  to  fluctuate  significantly  in  the  future.    Fluctuation  may  result  from  a 
variety of factors, which are discussed in detail throughout this ―RISK FACTORS‖ section, including: 

effects of aggressive competitors; 

research and development and manufacturing expenses; 

  our achievement of product development objectives and milestones; 
  demand and pricing for the Company‘s products; 
 
  hospital, clinic and physician buying decisions; 
 
  patient outcomes from our therapy; 
  physician acceptance of our products; 
  government or private healthcare reimbursement policies; 
  our manufacturing performance and capacity; 
 
 
 
 

incidents, if any, that could cause temporary shutdown of our manufacturing facility; 
the amount and timing of sales orders; 
rate and success of future product approvals; 
timing  of  FDA  clearance, if  any,  of competitive  products and the  rate  of  market  penetration  of 
competing products; 
seasonality of purchasing behavior in our market; 

 
  overall economic conditions; and 
 

the successful introduction or market penetration of alternative therapies. 

We Have Limited Data on the Clinical Performance of Cs-131.  As of June 1, 2008, the Proxcelan Cs-131 
seed has been implanted in over 2,800 patients and research papers are being published on the use of the 
Proxcelan  seed.    However,  we  have  less  statistical  data  than  is  available  for  I-125  and  Pd-103  seeds.  
While this limited data may prevent us from drawing statistically significant conclusions, the side effects 
experienced by these patients were less severe than side  effects observed in seed brachytherapy with I-
125  and  Pd-103  and  in  other  forms  of  treatment  such  as  radical  prostatectomy.    These  early  results 
indicate that the onset of side effects generally occurs between one and three weeks post-implant, and the 
side effects are resolved between five and eight weeks post-implant, side effects resolved more quickly 
than  the  side  effects  that  occur  with  competing  seeds  or  with  other  forms  of  treatment.    These  limited 
findings  support  management‘s  belief  that  the  Cs-131  seed  will  result  in  less  severe  side  effects  than 
competing treatments, but we  may have to  gather data on outcomes from additional patients before we 
can establish statistically valid conclusions regarding the incidence of side effects from our seeds. 

23 

 
 
 
 
 
We Are Subject To The Risk That Certain Third Parties May Mishandle Our Product.  We rely on third 
parties,  such  as  Federal  Express,  to  deliver  our  Proxcelan  Cs-131  seed,  and  on  other  third  parties, 
including  various  radiopharmacies,  to  package  our  Proxcelan  Cs-131  seed  in  certain  specialized 
packaging  forms  requested  by  customers.    We  are  subject  to  the  risk  that  these  third  parties  may 
mishandle our product, which could result in adverse effects, particularly given the radioactive nature of 
our product. 

It Is Possible That Other Treatments May Be Deemed Superior To Brachytherapy.  Our Proxcelan Cs-131 
seed faces competition not only from companies that sell other radiation therapy products, but also from 
companies  that  are  developing  alternative  therapies  for  the  treatment  of  cancers.    It  is  possible  that 
advances  in  the  pharmaceutical,  biomedical,  or  gene  therapy  fields  could  render  some  or  all  radiation 
therapies,  whether  conventional  or  brachytherapy,  obsolete.    If  alternative  therapies  are  proven  or  even 
perceived to offer treatment options that are superior to brachytherapy, physician adoption of our product 
could be negatively affected and our revenues from our product could decline. 

Our  Industry  Is  Intensely  Competitive.    The  medical  device  industry  is  intensely  competitive.    We 
compete with both public and private medical device, biotechnology and pharmaceutical companies that 
have  been  in  existence  longer  than  we  have,  have  a  greater  number  of  products  on  the  market,  have 
greater  financial  and  other  resources,  and  have  other  technological  or  competitive  advantages.    In 
addition, centers that wish to offer the Proxcelan Cs-131 seed must comply with licensing requirements 
specific to the state in which they do business and these licensing requirements may take a considerable 
amount of time to comply with.  Certain centers may choose to not offer our Proxcelan Cs-131 seed due 
to  the  time  required  to  obtain  necessary  license  amendments.    We  also  compete  with  academic 
institutions, government agencies, and private research organizations in the development of technologies 
and processes and in acquiring key personnel.  Although we have patents granted and patents applied for 
to  protect  our  isotope  separation  processes  and  Cs-131  seed  manufacturing  technology,  we  cannot  be 
certain  that  one  or  more  of  our  competitors  will  not  attempt  to  obtain  patent  protection  that  blocks  or 
adversely  affects  our  product  development  efforts.    To  minimize  this  potential,  we  have  entered  into 
exclusive  agreements  with  key  suppliers  of  isotopes  and  isotope  precursors,  which  are  subject  to 
becoming non-exclusive as we have failed to meet minimum purchase requirements. 

We May Be Unable To Adequately Protect Or Enforce Our Intellectual Property Rights Or Secure Rights 
To Third-Party Patents.  Our ability and the abilities of our partners to obtain and  maintain patent and 
other  protection  for  our  products  will  affect  our  success.    We  are  assigned,  have  rights  to,  or  have 
exclusive licenses to patents and patents pending in the U.S. and numerous foreign countries.  The patent 
positions  of  medical  device  companies  can  be  highly  uncertain  and  involve  complex  legal  and  factual 
questions.  Our patent rights may not be upheld in a court of law if challenged.  Our patent rights may not 
provide competitive advantages for our products and may be challenged, infringed upon or circumvented 
by our competitors.   We cannot patent our products in all countries or afford to litigate every potential 
violation worldwide. 

Because  of  the  large  number  of  patent  filings  in  the  medical  device  and  biotechnology  field,  our 
competitors  may  have  filed  applications  or  been  issued  patents  and  may  obtain  additional  patents  and 
proprietary  rights  relating  to  products  or  processes  competitive  with  or  similar  to  ours.    We  cannot  be 
certain  that  U.S.  or  foreign  patents  do  not  exist  or  will  not  be  issued  that  would  harm  our  ability  to 
commercialize our products and product candidates. 

The Value Of Our Granted Patent, and Our Patents Pending, Is Uncertain.  Although our management 
strongly  believes  that  our  patent  on  the  process  for  producing  Cs-131,  our  patent  pending  on  the 
manufacture of the brachytherapy seed, our patent applications on additional methods for producing Cs-
131 and other isotopes which have been filed, and anticipated future patent applications, which have not 
yet been filed, have significant value, we cannot be certain that other like-kind processes may not exist or 
be discovered, that any of these patents is enforceable, or that any of our patent applications will result in 
issued patents. 

24 

 
 
 
 
 
 
 
Failure To Comply With Government Regulations Could Harm Our Business.  As a medical device and 
medical isotope manufacturer, we are subject to extensive, complex, costly, and evolving governmental 
rules, regulations and restrictions administered by the FDA, by other federal and state agencies, and by 
governmental authorities in other countries.  Compliance with these laws and regulations is expensive and 
time-consuming, and changes to or failure to comply with these laws and regulations, or adoption of new 
laws and regulations, could adversely affect our business. 

In the United States, as a manufacturer of medical devices and devices utilizing radioactive by-product 
material, we are subject to extensive regulation by federal, state, and local governmental authorities, such 
as the FDA and the Washington State Department of Health, to ensure such devices are safe and effective.  
Regulations  promulgated  by  the  FDA  under  the  U.S.  Food,  Drug  and  Cosmetic  Act,  or  the  FDC  Act, 
govern the design, development, testing, manufacturing, packaging, labeling, distribution, marketing and 
sale,  post-market  surveillance,  repairs,  replacements,  and  recalls  of  medical  devices.    In  Washington 
State, the Department of Health, by agreement with the federal Nuclear Regulatory Commission (NRC), 
regulates the possession, use, and disposal of radioactive byproduct material as well as the manufacture of 
radioactive  sealed  sources  to  ensure  compliance  with  state  and  federal  laws  and  regulations.    Our 
Proxcelan Cs-131 brachytherapy seeds constitute both medical devices and radioactive sealed sources and 
are subject to these regulations. 

Under the FDC Act, medical devices are classified into three different categories, over which the FDA 
applies  increasing  levels  of  regulation:  Class I,  Class II,  and  Class III.    Our  Proxcelan  Cs-131  seed  has 
been  classified  as  a  Class  II  device  and  has  received  clearance  from  the  FDA  through  the  510(k)  pre-
market  notification  process.    Any  modifications  to  the  device  that  would  significantly  affect  safety  or 
effectiveness, or constitute a major change in intended use, would require a new 510(k) submission.  As 
with  any  submittal  to  the  FDA,  there  is  no  assurance  that  a  510(k)  clearance  would  be  granted  to  the 
Company. 

In  addition  to  FDA-required  market  clearances  and  approvals  for  our  products,  our  manufacturing 
operations are required to comply with the FDA's Quality System Regulation, or QSR, which addresses 
requirements  for  a  company's  quality  program  such  as  management  responsibility,  good  manufacturing 
practices, product and process design controls, and quality controls used in manufacturing.   Compliance 
with applicable regulatory requirements is monitored through periodic inspections by the FDA Office of 
Regulatory  Affairs  (ORA).    We  anticipate  both  announced  and  unannounced  inspections  by  the  FDA.  
Such inspections could result in non-compliance reports (Form 483) which, if not adequately responded 
to,  could  lead  to  enforcement  actions.    The  FDA  can  institute  a  wide  variety  of  enforcement  actions, 
ranging  from  public  warning  letters  to  more  severe  sanctions such  as  fines,  injunctions,  civil  penalties, 
recall  of  our  products,  operating  restrictions,  suspension  of  production,  non-approval  or  withdrawal  of 
pre-market clearances for new products or existing products, and criminal prosecution.  There can be no 
assurance that we will not incur significant costs to comply with these regulations in the future or that the 
regulations  will  not  have  a  material  adverse  effect  on  our  business,  financial  condition  and  results  of 
operations. 

The marketing of our products in foreign countries will, in general, be regulated by foreign governmental 
agencies similar to the FDA.  Foreign regulatory requirements vary from country to country.  The time 
and cost required to obtain regulatory approvals could be longer than that required for FDA clearance in 
the United States and the requirements for licensing a product in another country may differ significantly 
from  FDA  requirements.    We  will  rely,  in  part,  on  foreign  distributors  to  assist  us  in  complying  with 
foreign  regulatory  requirements.    We  may  not  be  able  to  obtain  these  approvals  without  incurring 
significant expenses or at all, and the failure to obtain these approvals would prevent us from selling our 
products in the applicable countries.  This could limit our sales and growth. 

Our Business Exposes Us To Product Liability Claims.  Our design, testing, development, manufacture, 
and  marketing  of  products  involve  an  inherent  risk  of  exposure  to  product  liability  claims  and  related 
adverse  publicity.    Insurance  coverage  is  expensive  and  difficult  to  obtain,  and,  although  we  currently 

25 

 
 
 
 
 
 
 
have  a  five  million  dollar  policy,  in  the  future  we  may  be  unable  to  obtain  or  renew  coverage  on 
acceptable terms, if at all.  If we are unable to obtain or renew sufficient insurance at an acceptable cost or 
if a successful product liability claim is made against us, whether fully covered by insurance or not, our 
business could be harmed. 

Our  Business  Involves  Environmental  Risks.    Our  business  involves  the  controlled  use  of  hazardous 
materials, chemicals, biologics, and radioactive compounds.  Manufacturing is extremely susceptible to 
product loss due to radioactive, microbial, or viral contamination; material or equipment failure; vendor 
or operator error; or due to the very nature of the product‘s short half-life.  Although we believe that our 
safety procedures for handling and disposing of such materials comply with state and federal standards 
there will always be the risk of accidental contamination or injury.  In addition, radioactive, microbial, or 
viral contamination may cause the closure of the respective manufacturing facility for an extended period 
of time.  By law, radioactive materials may only be disposed of at state-approved facilities.  At our leased 
facility we use commercial disposal contractors.  We may incur substantial costs related to the disposal of 
these materials.  If we were to become liable for an accident, or if we were to suffer an extended facility 
shutdown, we could incur significant costs, damages, and penalties that could harm our business. 

We Rely Upon Key Personnel.  Our success will depend, to a great extent, upon the experience, abilities 
and continued services of our executive officers, sales staff and key scientific personnel.  If we lose the 
services  of  several  officers,  sales  personnel,  or  key  scientific  personnel,  our  business  could  be  harmed.  
Our  success  also  will  depend  upon  our  ability  to  attract  and  retain  other  highly  qualified  scientific, 
managerial,  sales,  and  manufacturing  personnel  and  their  ability  to  develop  and  maintain  relationships 
with key individuals in the industry.  Competition for these personnel and relationships is intense and we 
compete  with  numerous  pharmaceutical  and  biotechnology  companies  as  well  as  with  universities  and 
non-profit  research  organizations.    We  may  not  be  able  to  continue  to  attract  and  retain  qualified 
personnel. 

Our Ability To Operate In Foreign Markets Is Uncertain.  Our future growth will depend in part on our 
ability  to  establish,  grow  and  maintain  product  sales  in  foreign  markets,  particularly  in  Canada  and 
Russia.  However, we have limited experience in marketing and distributing products in other countries.  
Any foreign operations would subject us to additional risks and uncertainties, including our customers‘ 
ability  to  obtain  reimbursement  for  procedures  using  our  products  in  foreign  markets;  the  burden  of 
complying  with  complex  and  changing  foreign  regulatory  requirements;  speedy  delivery  requirements 
due to the short half-life of our product; language barriers and other difficulties in providing long-range 
customer  service;  potentially  longer  accounts  receivable  collection  times;  significant  currency 
fluctuations, which could cause  third-party distributors to reduce the number of products they purchase 
from us because the cost of our products to them could fluctuate relative to the price they can charge their 
customers; reduced protection of intellectual property rights in some foreign countries; and the possibility 
that contractual provisions governed by foreign laws would be interpreted differently than intended in the 
event of a contract dispute.  Any future foreign sales of our products could also be adversely affected by 
export license requirements, the imposition of governmental controls, political and economic instability, 
trade restrictions, changes in tariffs, and difficulties in staffing and managing foreign operations.  Many of 
these factors may also affect our ability to import Cs-131 from Russia under our contracts with INM and 
RIAR. 

Our  Ability  To  Expand  Operations  And  Manage  Growth  Is  Uncertain.    Our  efforts  to  expand  our 
operations  will  result  in  new  and  increased  responsibilities  for  management  personnel  and  will  place  a 
strain upon the entire company.  To compete effectively and to accommodate growth, if any, we may be 
required to continue to implement and to improve our management, manufacturing, sales and marketing, 
operating and financial systems, procedures and controls on a timely basis and to expand, train, motivate 
and  manage  our  employees.    There  can  be  no  assurance  that  our  personnel,  systems,  procedures,  and 
controls will be adequate to support our future operations.  If the Proxcelan Cs-131 seed were to rapidly 
become the ―seed of choice,‖ it is unlikely that we could meet demand.  We could experience significant 
cash flow difficulties and may have difficulty obtaining the working capital required to manufacture our 
products and meet demand.  This would cause customer discontent and invite competition. 

26 

 
 
 
 
 
Our  Reporting  Obligations  As  A  Public  Company  Are  Costly.    Operating  a  public  company  involves 
substantial costs to comply with reporting obligations under federal securities laws that are continuing to 
increase  as  provisions  of  the  Sarbanes  Oxley  Act  of  2002  are  implemented.    As  a  smaller  reporting 
company, the Company needs to implement additional provisions of the Sarbanes Oxley Act during fiscal 
year 2009.  These reporting obligations will increase our operating costs. 

Our Stock Price Is Likely To Be Volatile.  There is generally significant volatility in the market prices and 
limited  liquidity  of  securities  of  early  stage  companies,  and  particularly  of  early  stage  medical  product 
companies.  Contributing to this volatility are various events that can affect our stock price in a positive or 
negative manner.  These events include, but are not limited to: governmental approvals of or refusals to 
approve regulations or actions; market acceptance and sales growth of our products; litigation involving 
the Company or our industry; developments or disputes concerning our patents or other proprietary rights; 
changes in the structure of healthcare payment systems; departure of key personnel; future sales of our 
securities; fluctuations in our financial results or those of companies that are perceived to be similar to us; 
swings  in  seasonal  demands  of  purchasers;  investors‘  general  perception  of  us;  and  general  economic, 
industry and market conditions.  If any of these events occur, it could cause our stock price to fall. 

Future Sales By Shareholders, Or The Perception That Such Sales May Occur, May Depress The Price 
Of Our Common Stock.  The sale or availability for sale of substantial amounts of our shares in the public 
market, including shares issuable upon conversion of outstanding preferred stock or exercise of common 
stock  warrants  and  options,  or  the  perception  that  such  sales  could  occur,  could  adversely  affect  the 
market  price  of  our  common  stock  and  also  could  impair  our  ability  to  raise  capital  through  future 
offerings of our shares.  As of June 30,  2008, we had 22,942,088 outstanding shares of common stock, 
and  the  following  additional  shares  were  reserved  for  issuance:  2,803,393  shares  upon  exercise  of 
outstanding  options,  3,245,082  shares  upon  exercise  of  outstanding  warrants,  and  59,065  shares  upon 
conversion of preferred stock.  Any decline in the price of our common stock may encourage short sales, 
which  could  place  further  downward  pressure  on  the  price  of  our  common  stock  and  may  impair  our 
ability to raise additional capital through the sale of equity securities. 

The Issuance Of Shares Upon Exercise Of Derivative Securities May Cause Immediate And Substantial 
Dilution To Our Existing Shareholders.   The issuance of shares upon conversion of the preferred stock 
and the exercise of common stock warrants and options may result in substantial dilution to the interests 
of other shareholders since these selling shareholders may ultimately convert or exercise and sell all or a 
portion of the full amount issuable upon exercise.  If all derivative securities were converted or exercised 
into shares of common stock, there would be approximately an additional 6,100,000 shares of common 
stock  outstanding  as  a  result.    The  issuance  of  these  shares  will  have  the  effect  of  further  diluting  the 
proportionate equity interest and voting power of holders of our common stock. 

We Do Not Expect To Pay Any Dividends For The Foreseeable Future.  We do not anticipate paying any 
dividends to our shareholders for the foreseeable future.  The terms of certain of our and our subsidiary's 
outstanding  indebtedness  substantially  restrict  the  ability  of  either  company  to  pay  dividends.  
Accordingly,  shareholders  must  be  prepared  to  rely  on  sales  of  their  common  stock  after  price 
appreciation to earn an investment return, which may never occur.  Any determination to pay dividends in 
the  future  will  be  made  at  the  discretion  of  our  Board  of  Directors  and  will  depend  on  our  results  of 
operations, financial conditions, contractual restrictions, restrictions imposed by applicable laws and other 
factors our Board deems relevant. 

Certain Provisions of Minnesota Law and Our Charter Documents Have an Anti-Takeover Effect.  There 
exist  certain  mechanisms  under  Minnesota  law  and  our  charter  documents  that  may  delay,  defer  or 
prevent  a  change  of  control.    Anti-takeover  provisions  of  our  articles  of  incorporation,  bylaws  and 
Minnesota law could diminish the opportunity for shareholders to participate in acquisition proposals at a 
price above the then-current market price of our common stock.  For example, while we have no present 
plans  to  issue  any  preferred  stock,  our  Board  of  Directors,  without  further  shareholder  approval,  may 
issue  shares  of  undesignated  preferred  stock  and  fix  the  powers,  preferences,  rights  and  limitations  of 
27 

 
 
 
 
 
 
 
such class or series, which could adversely affect the voting power of the common shares.  In addition, 
our  bylaws  provide  for  an  advance  notice  procedure  for  nomination  of  candidates  to  our  Board  of 
Directors that could have the effect of delaying, deterring or preventing a change in control.  Further, as a 
Minnesota  corporation,  we  are  subject  to  provisions  of  the  Minnesota  Business  Corporation  Act,  or 
MBCA,  regarding  ―business  combinations,‖  which  can  deter  attempted  takeovers  in  certain  situations.  
Pursuant to the terms of a shareholder rights plan adopted in February 2007, each outstanding share of 
common  stock  has  one  attached  right.    The rights  will  cause  substantial  dilution  of  the  ownership  of  a 
person or group that attempts to acquire the Company on terms not approved by the Board of Directors 
and  may  have  the  effect  of  deterring  hostile  takeover  attempts.    The  effect  of  these  anti-takeover 
provisions  may  be  to  deter  business  combination  transactions  not  approved  by  our  Board  of  Directors, 
including acquisitions that may offer a premium over the market price to some or all shareholders.  We 
may, in the future, consider adopting additional anti-takeover  measures.  The authority of our Board to 
issue undesignated preferred or other capital stock and the anti-takeover provisions of the MBCA, as well 
as  other  current  and  any  future  anti-takeover  measures  adopted  by  us,  may,  in  certain  circumstances, 
delay, deter or prevent takeover attempts and other changes in control of the Company not approved by 
our Board of Directors. 

ITEM 1B – UNRESOLVED STAFF COMMENTS 

None. 

ITEM 2 – PROPERTIES 

The Company‘s executive offices are located at 350 Hills Street, Suite 106, Richland, WA 99354, (509) 
375-1202, where IsoRay currently leases approximately 17,600 square feet of office and laboratory space 
for  approximately  $24,200  per  month  plus  monthly  janitorial  expenses  of  approximately  $600  from 
Energy Northwest, the owner of the Applied Process Engineering Laboratory (the APEL facility).  The 
Company is not affiliated with this lessor.  The monthly rent is subject to annual increases based on the 
Consumer Price Index.  The current lease was entered into in May 2007, expires on April 30, 2010, and 
has two three-year renewal options. 

The Company‘s management believes that all facilities occupied by the Company are adequate for present 
requirements,  and  that  the  Company‘s  current  equipment  is  in  good  condition  and  is  suitable  for  the 
operations involved. 

ITEM 3 – LEGAL PROCEEDINGS 

The Company is not involved in any material legal proceedings as of the date of this Report. 

ITEM 4 – SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS 

No  matter  was  submitted  to  a  vote  of  the  Company‘s  security  holders  during  the  fourth  quarter  of  the 
fiscal year covered by this Annual Report. 

PART II 

ITEM 5 – MARKET FOR REGISTRANT’S COMMON EQUITY, RELATED STOCKHOLDER 
MATTERS AND ISSUER PURCHASES OF EQUITY SECURITIES 

The  Company‘s  Articles  of  Incorporation  provide  that  the  Company  has  the  authority  to  issue 
200,000,000 shares of capital stock, which are currently divided into two classes as follows: 194,000,000 
shares of common stock, par value of $0.001 per share; and 6,000,000 shares of preferred stock, par value 
of $0.001 per share.  As of September 16, 2008, we had 22,942,088 outstanding shares of Common Stock 
and 59,065 outstanding shares of Preferred Stock.

On April 19, 2007, our common stock began trading on the American Stock Exchange (AMEX) under the 
symbol  "ISR."    Prior  to  this  our  common  stock  was  quoted  on  the  OTC  Bulletin  Board  and  the  Pink 
Sheets under the symbols ―ISRY.OB‖ and ―ISRY.PK,‖ respectively.  Even though we have obtained our 
AMEX listing, there is still limited trading activity in our securities. 

The  following  table  sets  forth,  for  the  fiscal  quarters  indicated,  the  high  and  low  sales  prices  for  our 
common  stock  as  reported  on  the  American  Stock  Exchange  and  the  OTC  Bulletin  Board.    The  OTC 
Bulletin  Board  quotations  are  high  and  low  last  reported  bid  prices  representing  inter-dealer  prices 
without  retail  mark-ups,  mark-downs  or  commissions,  and  may  not  necessarily  represent  actual 
transactions.  The quotations  may  be  rounded for  presentation.   In  the  past,  there  was an absence  of  an 
established  trading  market  for  the  Company's  common  stock,  as  the  market  was  limited,  sporadic  and 
highly volatile, which may have affected the prices listed below.

The Company has never paid any cash dividends on its Common Stock and does not plan to pay any cash 
dividends in the foreseeable future.  On February 1, 2007, the Board of Directors declared a dividend on 
the  Series  B  Preferred  Stock  of  all  outstanding  and  cumulative  dividends  through  December  31,  2006.  
There is no Series A Preferred Stock outstanding.  The total Series B dividends of $38,458 were paid on 
February 15, 2007.  The Company does not plan on paying any cash dividends on the Series B Preferred 
Stock in the foreseeable future.  There is no Series A Preferred Stock outstanding. 

As of September 16, 2008, we had approximately 365 shareholders of record, exclusive of shares held in 
street name. 

Equity Compensation Plans 

On  May  27,  2005,  the  Company  adopted  the  2005  Stock  Option  Plan  (the  Option  Plan)  and  the  2005 
Employee  Stock  Option  Plan  (the  Employee  Plan),  pursuant  to  which  it  may  grant  equity  awards  to 
eligible persons.  On August 15, 2006, the Company adopted the 2006 Director Stock Option Plan (the 
Director Plan) pursuant to which it may grant equity awards to eligible persons.  Each of the Plans has 
subsequently been amended.  The Option Plan allows the Board of Directors to grant options to purchase 
up to 1,800,000 shares of common stock to directors, officers, key employees and service providers of the 
Company,  and  the  Employee  Plan  allows  the  Board  of  Directors  to  grant  options  to  purchase  up  to 
2,000,000 shares  of  common  stock  to  officers  and  key  employees  of  the  Company.    The  Director  Plan 
allows  the  Board  of  Directors to  grant options  to  purchase up  to  1,000,000  shares  of common  stock  to 
directors  of  the  Company.    Options  granted  under  all  of  the  Plans  have  a  ten  year  maximum  term,  an 
exercise  price  equal  to  at  least  the  fair  market  value  of  the  Company‘s  common  stock  (based  on  the 
trading price on the American Stock Exchange or the OTC Bulletin Board) on the date of the grant, and 
with varying vesting periods as determined by the Board. 

As of June 30, 2008, the following options had been granted under the option plans.

ITEM 6 – SELECTED FINANCIAL DATA 

As a smaller reporting company, the Company is not required to provide Item 6 disclosure in this Annual 
Report. 

ITEM  7  –  MANAGEMENT’S  DISCUSSION  AND  ANALYSIS  OF  FINANCIAL  CONDITION 
AND RESULTS OF OPERATIONS 

Critical Accounting Policies and Estimates 

Management‘s discussion and analysis of the Company‘s financial condition and results of operations is 
based  upon  its  consolidated  financial  statements,  which  have  been  prepared  in  accordance  with 
accounting  principles  generally  accepted  in  the  United  States  of  America.    The  preparation  of  these 
financial  statements  requires  management  to  make  estimates  and  judgments  that  affect  the  reported 
amounts of assets, liabilities, revenues and expenses, and related disclosures of contingent liabilities.  On 
an  on-going  basis,  management  evaluates  past  judgments  and  estimates,  including  those  related  to  bad 
debts,  inventories,  accrued  liabilities,  and  contingencies.    Management  bases  its  estimates  on  historical 
30 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
   
 
 
 
 
 
 
 
 
 
 
 
 
   
 
 
 
 
 
   
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
experience and on various other assumptions that are believed to be reasonable under the circumstances, 
the results of which form the basis for making judgments about the carrying values of assets and liabilities 
that  are  not  readily  apparent  from  other  sources.    Actual  results  may  differ  from  these  estimates  under 
different assumptions or conditions. 

The Company believes the following critical accounting policies affect its more significant judgments and 
estimates used in the preparation of its consolidated financial statements. 

Short-Term Investments 

The  Company  invests  certain  excess  cash  in  marketable  securities  consisting  primarily  of  commercial 
paper,  auction  rate  securities,  and  money  market  funds.    The  Company  classifies  all  debt  securities  as 
―available-for-sale‖  and  records  the  debt  securities  at  fair  value  with  unrealized  gains  and  temporary 
unrealized  losses  included  in  other  comprehensive  income/loss  within  shareholders‘  equity,  if  material.  
Declines  in  fair  values  that  are  considered  other  than  temporary  are  recorded  in  the  Consolidated 
Statements of Operations. 

 Accounts Receivable 

Accounts receivable are stated at the amount that management of the Company expects to collect from 
outstanding balances.  Management provides for probable uncollectible amounts through an allowance for 
doubtful  accounts.    Additions  to  the  allowance  for  doubtful  accounts  are  based  on  management‘s 
judgment,  considering  historical  write-offs,  collections  and  current  credit  conditions.    Balances  which 
remain  outstanding  after  management  has  used  reasonable  collection  efforts  are  written  off  through  a 
charge  to  the  allowance  for  doubtful  accounts  and  a  credit  to  the  applicable  accounts  receivable.  
Payments  received  subsequent  to  the  time  that  an  account  is  written  off  are  considered  bad  debt 
recoveries. 

Inventory 

Inventory  is  reported  at  the  lower  of  cost  or  market.    Cost  of  raw  materials  is  determined  using  the 
weighted average method.  Cost of work in process and finished goods is computed using standard cost, 
which approximates actual cost, on a first-in, first-out basis.  As the Company has operated at a gross loss 
throughout  the  past  fiscal  years,  inventories  have  generally  been  recorded  at  market  or  net  realizable 
value. 

Fixed Assets 

Fixed assets are capitalized and carried at the lower of cost or net realizable value.  Normal maintenance 
and repairs are charged to expense as incurred.  When assets are sold or otherwise disposed of, the cost 
and accumulated depreciation are removed from the accounts and any resulting gain or loss is recognized 
in operations.  

Depreciation is computed using the straight-line method over the following estimated useful lives: 

Production equipment 
Office equipment 
Furniture and fixtures 

3 to 7 years 
2 to 5 years 
2 to 5 years 

Leasehold improvements and capital lease assets are amortized over the shorter of the life of the lease or 
the estimated useful life of the asset. 

The  Company  has  adopted  the  provisions  of  Statement  of  Financial  Accounting  Standards (SFAS)  No. 
144, Accounting for the Impairment or Disposal of Long-Lived Assets.  The provisions of SFAS No. 144 
require that  an impairment  loss  be  recognized  when  the  estimated  future  cash  flows  (undiscounted  and 
without interest) expected to result from the use of an asset are less than the carrying amount of the asset.  

31 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Measurement  of  an  impairment  loss  is  based  on  the  estimated  fair  value  of  the  asset  if  the  asset  is 
expected to be held and used. 

Management  of  the  Company  periodically  reviews  the  net carrying  value  of  all  of  its equipment  on  an 
asset  by  asset  basis.    These  reviews  consider  the  net  realizable  value  of  each  asset,  as  measured  in 
accordance with the preceding paragraph, to determine whether an impairment in value has occurred, and 
the need for any asset impairment write-down.  

Although  management  has  made  its best  estimate  of the factors  that  affect the carrying  value  based on 
current  conditions,  it  is  reasonably  possible  that  changes  could  occur  which  could  adversely  affect 
management's estimate of net cash flows expected to be generated from its assets, and necessitate asset 
impairment write-downs. 

Deferred Financing Costs 

Financing costs related to the acquisition of debt are deferred and amortized over the term of the related 
debt  using  the  effective  interest  method.    Deferred  financing  costs  include  the  fair  value  of  common 
shares  issued  to  certain  shareholders  for  their  guarantee  of  certain  Company  debt  in  accordance  with 
Accounting Principles Board (APB) Opinion No. 21, Interest on Receivables and Payables and Emerging 
Issues Task Force (EITF) Issue  No. 95-13,  Classification of Debt Issue Costs in the Statement of Cash 
Flows.    The  value  of  the  shares  issued  was  the  estimated  market  price  of  the  shares  as  of  the  date  of 
issuance.    Amortization of  deferred financing  costs, totaling  $30,504  and  $178,633  for the  years  ended 
June 30, 2008 and 2007, respectively, is included in financing expense on the statements of operations. 

Licenses 

Amortization of licenses is computed using the straight-line method over the estimated economic useful 
lives of the assets.  In fiscal year 2006, the Company entered into an agreement with IBt, SA, a Belgian 
company  (IBt)  to  use  IBt‘s  proprietary  ―Ink  Jet‖  production  process  and  its  proprietary  polymer  seed 
technology for use in brachytherapy procedures using Cesium-131 (Cs-131).  The Company paid license 
fees  of  $225,000  and  $275,000  during  fiscal  years  2008  and  2006,  respectively,  and  is  amortizing  the 
license over the 15-year term of the license agreement. 

In the fourth quarter of fiscal year 2008, the Company reviewed the carrying values of licenses.  Although 
the Company has not currently integrated this technology into its products, management will reevaluate 
the potential of this technology during fiscal year 2009 after the Company has further improved its current 
processes.  Therefore, the Company did not believe that any impairment had occurred to this intangible 
asset. 

Amortization  of  licenses  was  $43,452  and  $23,426  for  the  years  ended  June  30,  2008  and  2007, 
respectively.  Based on the licenses recorded at June 30, 2008, and assuming no subsequent impairment 
of the underlying assets, the annual amortization expense for each fiscal year ending June 30 is expected 
to be as follows:  $47,670 for 2009, $35,354 for 2010, $35,208 for 2011, $35,208 for 2012, $35,208 for 
2013, and $266,998 thereafter. 

Other Assets 

Other  assets,  which  include  deferred  charges  and  patents,  are  stated  at  cost,  less  accumulated 
amortization.    Amortization  of  patents  is  computed  using  the  straight-line  method  over  the  estimated 
economic useful lives of the assets.  The Company periodically reviews the carrying values of patents and 
any impairments are recognized when the expected future operating cash flows to be derived from such 
assets are less than their carrying value. 

Based on the patents and other intangible assets recorded in other assets at June 30, 2008, and assuming 
no subsequent impairment of the underlying assets, the annual amortization expense for each fiscal year 

32 

 
 
 
 
 
 
 
 
 
 
 
 
 
ending June 30 is expected to be as follows: $7,798 for 2009, $4,353 for 2010, $2,632 for 2011, $2,632 
for 2012, $2,632 for 2013, and $9,560 thereafter. 

Asset Retirement Obligation 

SFAS No. 143, Asset Retirement Obligations, establishes standards for the recognition, measurement and 
disclosure  of  legal  obligations  associated  with  the  costs to  retire long-lived  assets.    Accordingly,  under 
SFAS No. 143, the fair value of the future retirement costs of the Company‘s leased assets are recorded as 
a  liability  on  a  discounted  basis  when  they  are  incurred  and  an  equivalent  amount  is  capitalized  to 
property  and  equipment.    The  initial  recorded  obligation  is  discounted  using  the  Company‘s  credit-
adjusted risk free-rate and is reviewed periodically  for changes in the estimated future costs underlying 
the  obligation.    The  Company  amortizes  the  initial  amount  capitalized  to  property  and  equipment  and 
recognizes  accretion  expense  in  connection  with  the  discounted  liability  over  the  estimated  remaining 
useful life of the leased assets. 

In  fiscal  year  2006,  the  Company  established  an  initial  asset  retirement  obligation  of  $63,040  which 
represented the discounted cost of cleanup that the Company anticipated it would have to incur at the end 
of its equipment and property leases in its old production facility.  This amount was determined based on 
discussions with qualified production personnel and on historical evidence.  During fiscal year 2007, the 
Company reevaluated its obligations based on discussions with the Washington Department of Health and 
determined  that  the  initial  asset  retirement  obligation  should  be  increased  by  an  additional  $56,120.  
During the second quarter of fiscal year 2008, the Company removed all radioactive residuals and tenant 
improvements from its old production facility and returned the facility to the lessor.  The Company had an 
asset retirement obligation of $135,120 accrued for this facility but total costs incurred to decommission 
the  facility  were  $274,163  resulting  in  an  additional  expense  of  $139,043  that  is  included  in  cost  of 
products sold.  The additional expense  was mainly due to unanticipated construction costs to return the 
facility to its previous state.  The Company originally believed that the lessor would retain many of the 
leasehold improvements in the building, but the lessor instead required their removal. 

In  September  2007,  another  asset  retirement  obligation  of  $473,096  was  established  representing  the 
discounted cost of the Company‘s estimate of the obligations to remove any residual radioactive materials 
and all leasehold improvements at the end of the lease term at its new production facility.  The estimate 
was  developed  by  qualified  production  personnel  and  the  general  contractor  of  the  new  facility.    The 
Company has reviewed the estimate again based on its experience with decommissioning its old facility 
and believes that the original estimate continues to be applicable. 

During the years ended June 30, 2008 and 2007, the asset retirement obligation changed as follows: 

Beginning balance 
New obligations 
Settlement of existing obligation 
Changes in estimates of existing obligations 
Accretion of discount

Because the Company does not expect to incur any expenses related to its asset retirement obligations in 
fiscal year 2009, the entire balance as of June 30, 2008 is classified as a noncurrent liability. 

Financial Instruments 

The Company discloses the fair value of financial instruments, both assets and liabilities, recognized and 
not recognized in the balance sheet, for which it is practicable to estimate the fair value.  The fair value of 

33 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
a financial instrument is the amount at which the instrument could be exchanged in a current transaction 
between willing parties, other than a forced liquidation sale. 

The  carrying  amounts  of  financial  instruments,  including  cash  and  cash  equivalents,  short-term 
investments,  accounts  receivable,  accounts  payable,  notes  payable,  and  capital  lease  obligations, 
approximated their fair values at June 30, 2008 and 2007. 

Revenue Recognition 

The  Company  applies  the  provisions  of  SEC  Staff  Accounting  Bulletin  (SAB)  No. 104,  Revenue 
Recognition.  SAB  No. 104,  which  supersedes  SAB  No. 101,  Revenue  Recognition  in  Financial 
Statements,  provides  guidance  on  the  recognition,  presentation  and  disclosure  of  revenue  in  financial 
statements.  SAB No. 104 outlines the basic criteria that must be met to recognize revenue and provides 
guidance for the disclosure of revenue recognition policies.  The Company recognizes revenue related to 
product sales when (i) persuasive evidence of an arrangement exists, (ii) shipment has occurred, (iii) the 
fee is fixed or determinable, and (iv) collectability is reasonably assured. 

Revenue for the fiscal years ended June 30, 2008 and 2007 was derived solely from sales of the Proxcelan 
Cs-131 brachytherapy seed, which is used in the treatment of cancer.  The Company recognizes revenue 
once the product has been shipped to the customer.  Prepayments, if any, received from customers prior to 
the  time  that  products  are  shipped  are  recorded  as  deferred  revenue.  In  these  cases,  when  the  related 
products are shipped, the amount recorded as deferred revenue is recognized as revenue.  The Company 
accrues for sales returns and other allowances at the time of shipment.  Although the Company does not 
have  an  extensive  operating  history  upon  which  to  develop  sales  returns  estimates,  we  have  used  the 
expertise of our management team, particularly those with extensive industry experience and knowledge, 
to develop a proper methodology. 

Stock-Based Compensation 

The Company measures and recognizes expense for all share-based payments at fair value in accordance 
with  SFAS  No.  123 (Revised  2004),  Share-Based  Payment  (SFAS  No.  123R).   The  Company  uses the 
Black-Scholes option valuation model to estimate fair value for all stock options on the date of grant.  For 
stock options that vest over time, the Company recognizes compensation cost on a straight-line basis over 
the requisite service period for the entire award. 

Research and Development Costs 

Research  and  development  costs,  including  salaries,  research  materials,  administrative  expenses  and 
contractor  fees,  are  charged  to  operations  as  incurred.    The  cost  of  equipment  used  in  research  and 
development activities which has alternative uses is capitalized as part of fixed assets and not treated as 
an expense in the period acquired.  Depreciation of capitalized equipment used to perform research and 
development is classified as research and development expense in the year recognized. 

Legal Contingencies 

In the ordinary course of business, the Company is involved in legal proceedings involving contractual 
and employment relationships, product liability claims, patent rights, environmental matters, and a variety 
of  other  matters.    The  Company  is  also  subject  to  various  local,  state,  and  federal  environmental 
regulations  and  laws  due  to  the  isotopes  used  to  produce  the  Company‘s  product.    As  part  of  normal 
operations,  amounts  are  expended  to  ensure  that  the  Company  is  in  compliance  with  these  laws  and 
regulations.  While there have been no reportable incidents or compliance issues, the Company believes 
that if it relocates its current production facilities then certain decommissioning expenses will be incurred 
and has recorded an asset retirement obligation for these expenses. 

34 

 
 
 
 
  
 
 
 
 
 
 
 
The Company records contingent liabilities resulting from asserted and unasserted claims against it, when 
it  is  probable  that  a  liability  has  been  incurred  and  the  amount  of  the  loss  is  reasonably  estimable.  
Estimating probable losses requires analysis of multiple factors, in some cases including judgments about 
the potential actions of third-party claimants and courts.  Therefore, actual losses in any future period are 
inherently uncertain.  Currently, the Company does not believe any probable legal proceedings or claims 
will have a material adverse effect on its financial position or results of operations.  However, if actual or 
estimated probable future losses exceed the Company‘s recorded liability for such claims, it would record 
additional  charges  as  other  expense  during  the  period  in  which  the  actual  loss  or  change  in  estimate 
occurred. 

Income Taxes 

Income  taxes  are  accounted  for  under  the  liability  method.    Under  this  method,  the  Company  provides 
deferred income taxes for temporary differences that will result in taxable or deductible amounts in future 
years based on the reporting of certain costs in different periods for financial statement and income tax 
purposes.    This  method  also  requires  the  recognition  of  future  tax  benefits  such  as  net  operating  loss 
carryforwards, to the extent that realization of such benefits is more likely than not.   Deferred tax assets 
and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in 
which  those  temporary  differences  are  expected  to  be  recovered  or  settled.    The  effect  on  deferred  tax 
assets and liabilities  of  a change  in tax rates is recognized  in  operations  in  the period  that  includes the 
enactment of the change. 

On  July  1,  2007,  the  Company  adopted  Financial  Accounting  Standards  Board  Interpretation  No.  48, 
Accounting  for  Uncertainty  in  Income  Taxes  (FIN  No.  48).    FIN  No.  48  clarifies  the  accounting  for 
uncertainty in income taxes recognized in accordance with SFAS No. 109, Accounting for Income Taxes, 
prescribing a recognition threshold and measurement attribute for the recognition and measurement of a 
tax position taken or expected to be taken in a tax return.  In the course of its assessment, management has 
determined  that  the  Company,  its  subsidiary,  and  its  predecessors  are  subject  to  examination  of  their 
income tax filings in the United States and state jurisdictions for the 2005 through 2007 tax years.  In the 
event that the Company is assessed penalties and or interest, penalties will be charged to other operating 
expense and interest will be charged to interest expense. 

The Company adopted FIN No. 48 using the modified prospective transition method, which requires the 
application  of  the  accounting  standard  as  of  July  1,  2007.    There  was  no  impact  on  the  financial 
statements  as  of  and  for  the  year  ended  June  30,  2008  as  a  result  of  the  adoption  of  FIN  No.  48.    In 
accordance  with  the  modified  prospective  transition  method,  the  financial  statements  for  prior  periods 
have not been restated to reflect, and do not include, the impact of FIN No. 48. 

Income (Loss) Per Common Share 

The  Company  accounts  for  its  income  (loss)  per  common  share  according  to SFAS  No.  128,  Earnings 
Per  Share.  Basic  earnings  per  share  is  calculated  by  dividing  net  income  (loss)  available  to  common 
shareholders  by  the  weighted  average number  of  common  shares  outstanding,  and  does  not include the 
impact  of  any  potentially  dilutive  common  stock  equivalents.    Common  stock  equivalents,  including 
warrants and options to purchase the Company's common stock, are excluded from the calculations when 
their effect is antidilutive.  At June 30, 2008 and 2007, the calculation of diluted weighted average shares 
does not include preferred stock, common stock warrants or options that are potentially convertible into 
common stock as those would be antidilutive due to the Company‘s net loss position. 

Securities that could be dilutive in the future as of June 30, 2008 and 2007 are as follows:

Use of Estimates 

The preparation of financial statements in accordance with accounting principles generally accepted in the 
United States of America requires management of the Company to make estimates and assumptions that 
affect  the  amounts  reported  in  the  financial  statements  and  accompanying  notes.    Accordingly,  actual 
results could differ from those estimates and affect the amounts reported in the financial statements. 

Results of Operations 

Financial Presentation 

The  following  sets  forth  a  discussion  and  analysis  of  the  Company‘s  financial  condition  and  results  of 
operations for the two years ended June 30, 2008 and 2007.  This discussion and analysis should be read 
in conjunction with our consolidated financial statements appearing elsewhere in this Annual Report on 
Form 10-K.  The following discussion contains forward-looking statements.  Our actual results may differ 
significantly from the results discussed in such forward-looking statements.  Factors that could cause or 
contribute  to  such  differences  include,  but  are  not  limited  to,  those  discussed  in  ―Item 1A —  Risk 
Factors,‖ beginning on page 21 of this Annual Report on Form 10-K. 

Year ended June 30, 2008 compared to year ended June 30, 2007 

Product  sales.    Sales  for  the  year  ended  June  30,  2008  were  $7,158,690  compared  to  sales  of 
$5,738,033  for  the  year  ended  June  30,  2007.    The  increase  of  $1,420,657  or  25%  was  due  to 
increased  sales  volume  of  the  Company‘s  Proxcelan  Cs-131  brachytherapy  seeds.    During  the 
year ended June 30, 2008 the Company sold its Cs-131 seeds to 99 different medical centers as 
compared to 79 centers during the fiscal year ended June 30, 2007. 

Cost of product sales.  Cost of product sales were $7,310,124 for the year ended June 30, 2008 
which  represents  an  increase  of  $1,517,494  or  26%  compared  to  cost  of  product  sales  of 
$5,792,630  for  the  year  ended  June  30,  2007.    The  major  components  of  the  increase  were 
depreciation, materials, preload expenses, occupancy costs, and expenses related to the transition 
to the Company‘s new production facility and decommissioning the Company‘s old production 
facility.  These increases were partially offset by decreases in consulting and shipping expenses. 

Depreciation increased approximately $613,000 due to moving operations into a new production 
facility  and  purchasing  new  production  equipment.    This  new  production  facility  allowed  the 
Company to increase its available capacity by approximately 300% using its current production 
techniques  and should  fulfill  the  Company‘s  production  needs for  the  near future.    The  cost  of 
materials  increased  approximately  $313,000  mainly  due  to  higher  sales  volumes.    Preload 
expenses increased approximately $250,000 due to higher sales volumes and due to the start-up 
costs  of  the  Company‘s  internal  preload  facility.    Occupancy  costs  increased  approximately 
$164,000 as the Company entered into a lease for a new production facility in March 2007 and 
continued to pay rent on its old production facility through mid-December 2007.  The Company 
also  recorded  an  impairment  charge  of  $85,000  in  fiscal  year  2008  for  a  hot  cell  that  is  not 
currently in use. 

The Company also experienced increases in cost of product sales expenditures directly related to 
the  new  facility  that  was  opened  in  September  2007.    To  ensure  a  smooth  transition  with  no 
missed  order  shipments,  the  Company  ordered  an  additional  $38,000  of  isotope  in  September 
2007 that was not utilized as the removal and transportation of the isotope from the old facility to 
the new facility presented logistical challenges that made it cost prohibitive.  As part of opening 
the  new  facility,  the  Company  incurred  approximately  $20,000  of  wages  and  related  taxes  for 

36 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
personnel  to  perform  equipment  set-up  and  validation.    The  Company  also  expensed 
approximately $82,000 of production materials and small tools for the new facility, none of which 
individually  exceeded  the  $2,500  threshold  the  Company  uses  in  determining  whether  to 
capitalize production equipment. 

The Company removed all radioactive residuals and tenant improvements from its old production 
facility and returned the facility to the lessor.  The Company had an asset retirement obligation of 
$135,120  accrued  for  this  facility  but  total  costs  incurred  to  decommission  the  facility  were 
$274,163 resulting in an additional expense of $139,043 that is included in cost of products sold.  
The additional expense was mainly due to unanticipated construction costs to return the facility to 
its  previous  state.    The  Company  originally  believed  that  the  lessor  would  retain  many  of  the 
leasehold improvements in the building, but instead required their removal. 

These  increases  were  partially  offset  by  a  decrease  of  approximately  $75,000  in  consulting 
expenses as the previous year included costs related to medical physics and equipment design and 
approximately  $72,000  in  shipping  and  freight  as  the  Company  eliminated  certain  shipping 
services. 

Gross  loss.    Gross  loss  was  $151,434  for  the  year  ended  June  30,  2008.    This  represents  an 
increase of $96,837 or 177% over the prior year‘s gross loss of $54,597.  The increase is due to 
the  increase  in  production  costs  more  than  offsetting  the  increase  in  revenues.    However,  the 
Company has worked to reduce its production costs over the past six months and is producing its 
Proxcelan Cs-131 brachytherapy seeds more efficiently now. 

Research and development expenses.  Research and development expenses for the year ended 
June 30, 2008 were $1,358,075 which represents an increase of $12,912 or 1% over the research 
and development expenses of $1,345,163 for the year ended June 30, 2007.  Although the overall 
research  and  development  expenses  were  consistent  with  the  prior  year,  consulting  expenses 
increased  approximately  $189,000  due  to  the  Company‘s  ongoing  project  to  increase  the 
efficiency  of  isotope  production  and  travel  expenses  increased  approximately  $25,000  due  to 
work  in  Russia  regarding  isotope  efficiencies.    These  increases  were  offset  by  a  decrease  of 
approximately $205,000 in legal expenses as the Company continues to focus on its key patents 
and trademarks in strategic countries and deemphasized the protection of patents and trademarks 
in less strategic countries. 

Sales  and  marketing  expenses.    Sales  and  marketing  expenses  were  $3,725,164  for  the  year 
ended  June  30,  2008.    This  represents  an  increase  of  $340,692  or  10%  compared  to  the  year 
ended June 30, 2007 sales and marketing expenses of $3,384,472.  The change is mainly due to 
increased  personnel  costs and  consulting  expenses  partially  offset  by  a decrease  in  conventions 
and tradeshows.  Personnel costs increased approximately $333,000 due to higher commissions 
paid  on  increased  revenues  and  an  increase  in  the  average  headcount.    Consulting  expenses 
increased  approximately  $103,000  mainly  due  to  payments  to  consultants  to  develop  technical 
publications  and  other  materials,  to  represent  the  Company  at  professional  society  meetings,  to 
serve  as  members  of  the  Company‘s  Cesium  Advisory  Group,  and  increased  expenses  for  a 
lobbying  group.    Conventions  and  tradeshows  decreased  approximately  $130,000  as  the 
Company  has  reduced  its  budgets  for  many  of  the  tradeshows,  particularly  the  smaller 
tradeshows. 

General and administrative expenses.  General and administrative expenses for the year ended 
June 30, 2008 were $3,568,048 compared to general and administrative expenses of $4,915,598 
for  the  year  ended  June  30,  2007.    The  decrease  of  $1,347,550  or  27%  is  primarily  due  to  a 
decrease  in  share-based  compensation,  personnel  costs,  and  travel.    These  decreases  were 
partially  offset  by  an  increase  in  legal  expenses.    Share-based  compensation  decreased 
approximately $1.2 million due to reduced option awards in fiscal year 2008 and the reversal of 
expense for unvested and forfeited options for  Roger Girard, the former CEO.  Personnel costs 

37 

 
 
 
 
 
 
 
decreased approximately $115,000 mainly due to the resignation of Mr. Girard in February 2008.  
Travel  decreased  approximately  $104,000.    Legal  expenses  increased  approximately  $159,000 
due to costs to draft contracts regarding the Company‘s interest in UralDial, LLC, a new Russian 
entity, the IBt strategic global alliance agreements, and mediation costs related to negotiations to 
settle a dispute with the Lawrence Family Trust. 

Operating  loss.    The  Company  continues  to  focus  its  resources  on  marketing  and  sales  and 
retaining  the  administrative  infrastructure  to  increase  the  level  of  demand  for  the  Company‘s 
product.    These  costs,  coupled  with  product  revenues  not  covering  production  costs,  and 
significant  research  and  development  expenditures,  have  resulted  in  operating  losses  since  its 
inception.  For the year ended June 30, 2008, the Company had an operating loss of $8,802,721 
which is a decrease of $897,109 or 9% below the operating loss of $9,699,830 for the year ended 
June 30, 2007. 

Interest  and  investment  income.    Interest  and  investment  income  was  $612,077  for  the  year 
ended June 30, 2008 compared to interest income of $406,921 for the year ended June 30, 2007.  
Interest and investment income is mainly derived from excess funds held in money market and 
investment accounts.  The increase of $205,156 or 50% was due to the higher average cash and 
short-term investment balances during the year ended June 30, 2008 partially offset by decreasing 
interest rates. 

Loss on short-term investments.  The loss of $274,000 for the year ended June 30, 2008 is due 
to the recent uncertainties in the credit markets particularly for certain auction rate securities held 
by the Company.  The loss represents the amount to write-down these securities to their estimated 
fair  market  value.    The  Company  has  recognized  these  losses  as  other  than  temporary  and 
recorded  them  in  the  statement  of  operations rather  than  in  other  comprehensive  income  as  the 
Company may need access to these funds before the uncertainties in the credit markets are fully 
resolved. 

Financing  expense.    Financing  expense  for  the  year  ended  June  30,  2008  was  $92,863  or  a 
decrease of $219,383 or 70% compared to financing expense of $312,246 for the year ended June 
30,  2008.    Included  in  financing  expense  is  interest  expense  of  approximately  $62,000  and 
$134,000 for the years ended June 30, 2008 and 2007, respectively.  The decrease is due to the 
lower average debt balances in the year ended June 30, 2008.  The remaining balance of financing 
expense represents the amortization of deferred financing costs which decreased due to the write-
off in fiscal year 2007 of the deferred financing costs relating to the Columbia River Bank line of 
credit. 

Liquidity  and  capital  resources.    We  have  historically  financed  our  operations  through  the  sale  of 
common stock and related warrants.  During fiscal year 2008, the Company‘s primary source of cash was 
the exercise of common stock warrants and options for $1,022,813 and the Company used existing cash 
reserves to fund its operations and capital expenditures. 

Cash flows from operating activities 

Cash used in operating activities was $7.7 million in fiscal year 2008 compared to $7.2 million in fiscal 
year 2007, an increase of approximately $500,000.  Cash used by operating activities is net loss adjusted 
for non-cash items and changes in operating assets and liabilities. 

Cash flows from investing activities 

In 2008, the Company invested its excess cash generated from shareholder investments.  During 2008, the 
Company purchased approximately $13.3 million of various short-term investments (mainly commercial 
paper  and  municipal  auction  rate  securities)  and  sold  approximately  $19.4  million  of  short-term 

38 

 
 
 
 
 
 
 
 
 
 
investments.    As  of  June  30,  2008,  short-term  investments  held  by  the  Company  amounted  to 
approximately $3.7 million. 

Cash expenditures for fixed assets were approximately $3.1 million in fiscal 2008 and approximately $2.4 
million in fiscal 2007.  The increase is mainly due to construction to complete our new production facility 
and equipment purchases for the new facility. 

Cash flows from financing activities 

The Company issued 300,876 shares of common stock pursuant to the exercise of common stock options 
and warrants.  The Company received $1,022,813 in cash pursuant to these exercises. 

Projected 2009 Liquidity and Capital Resources 

At  June  30,  2008,  cash  and  cash  equivalents  amounted  to  $4,820,033  and  short-term  investments 
amounted to $3,726,000 compared to $9,335,730 of cash and cash equivalents and $9,942,840 of short-
term investments at June 30, 2007. 

The Company had approximately $4.0 million of cash and $3.7 million of short-term investments as of 
September  16, 2008.    As of  that  date  management  believed  that the  Company‘s  monthly  required cash 
operating  expenditures  were  approximately  $400,000.    Management  believes  that  approximately 
$200,000  to  $500,000  will  be  spent  on  capital  expenditures  during  fiscal  year  2009,  but  there  is  no 
assurance that unanticipated needs for capital equipment may not arise. 

If the Company is able to complete its major research and development project to develop a  proprietary 
separation  process  to  manufacture  enriched  barium,  this  process  should  improve  isotope  production 
efficiency  during  fiscal  year  2009.    Regardless  of  whether  the  Company  is  ultimately  successful  in 
developing this process, the remaining project costs are anticipated to be approximately $150,000. 

During  fiscal  year  2009, the  Company  intends  to  continue  its  existing  protocol  studies  and  is  currently 
budgeting approximately $278,000 for protocol expense in fiscal year 2009. 

Assuming operating costs expand proportionately with revenue increases, other applications are pursued 
for seed usage outside the prostate market, protocols are continued supporting the integrity of our product 
and  sales  and  marketing  expenses  remain  steady,  management  believes  the  Company  will  reach 
breakeven with revenues of approximately $1.5 million per month.  This is a decrease from the previous 
estimate of $2 million in monthly revenue based on actions taken by new management that have over the 
past six months begun to improve the Company‘s production operating efficiencies and its cost structure. 

Based  on  the  foregoing  assumptions,  management  believes  cash,  cash  equivalents,  and  short-term 
investments  on  hand  at  June 30,  2008  will  be  sufficient  to  meet  our  anticipated  cash  requirements  for 
operations,  debt  service,  and  capital  expenditure  requirements  through  at  least  the  next  twelve  months.  
Management‘s plans to attain breakeven and generate additional cash flows include increasing revenues 
from both new and existing customers and maintaining cost control.  However, there can be no assurance 
that the Company will attain profitability or that the Company will be able to attain its aggressive revenue 
targets.    If  we  do  not  experience  the  necessary  increases  in  sales  or  if  we  experience  unforeseen 
manufacturing constraints, we may need to obtain additional funding. 

The Company expects to finance its future cash needs through the sale of equity securities and possibly 
strategic  collaborations  or  debt  financing  or  through  other  sources  that  may  be  dilutive  to  existing 
shareholders.  If the Company needs to raise additional money to fund its operations, funding may not be 
available  to  it  on  acceptable  terms,  or  at  all.  If  the  Company  is  unable  to  raise  additional  funds  when 
needed,  it  may  not  be  able  to  market  its  products  as  planned  or  continue  development  and  regulatory 
approval of its future products.  If the Company raises additional funds through equity sales, these sales 
may be dilutive to existing investors.

Long-Term Debt and Capital Lease Agreements 

The  Company  has  two  loan  facilities  in  place  as  of June  30,  2008.    The  first  loan  is  from  the  Benton-
Franklin Economic Development District (BFEDD) in an original principal amount of $230,000 and was 
funded in December 2004.  It bears interest at eight percent and has a 60-month term with a final balloon 
payment.  As of June 30, 2008, the principal balance owed was $145,745.  This loan is secured by certain 
equipment,  materials  and  inventory  of  IsoRay,  and  also  required  personal  guarantees,  for  which  the 
guarantors  were  issued  approximately  70,455  shares  of  common  stock.    The  second  loan  is  from  the 
Hanford Area Economic Investment Fund Committee (HAEIFC) and was originated in June 2006.  The 
loan originally had a total facility of $1,400,000 which was reduced in September 2007 to the amount of 
the Company‘s initial draw of $418,670.  The principal balance owed on the loan as of June 30, 2008 was 
$263,639.    This  loan  is  secured  by  receivables,  equipment,  materials  and  inventory,  and  certain  life 
insurance policies and also required personal guarantees.  

The BFEDD has granted the Company a waiver from enforcing violations of paying officers in excess of 
$100,000 per year and maintaining a certain current asset ratio.  The waiver is effective through June 30, 
2009  and  also  waives  non-compliance  with  covenants  prohibiting  fixed  asset  or  lease  obligations  in 
excess  of  $24,000  per  year,  covenants  prohibiting  mergers,  and  covenants  requiring  maintenance  of  a 
certain long-term debt to equity ratio. 

HAEIFC  has  also  granted  the  Company  a  waiver  from  enforcing  a  fixed  charge  coverage  ratio.    The 
waiver is effective through June 30, 2009. 

The  Company  has  certain  capital  leases  for  production  equipment  that  expire  at  various  times  from 
September 2008 to April 2009.  These leases  currently call for total monthly payments of  $3,876.  The 
total of all capital lease obligations at June 30, 2008 was $25,560. 

Principal maturities on notes payable as of June 30, 2008 are due as follows:

On  May  2,  2007,  Medical  entered  into  a  lease  for  its  new  production  facility  with  Energy  Northwest,  the 
owner of the Applied Process Engineering Laboratory (the APEL lease).  The APEL lease has a three-year

term  expiring  on  April  30,  2010,  an  option  to  renew  for  two  additional  three-year  terms,  and  original 
monthly rent of approximately $26,700, subject to annual increases based on the Consumer Price Index, 
plus  monthly  janitorial  expenses  of  approximately  $700.    This  new  facility  became  operational  in 
September 2007. 

Future  minimum  lease  payments  under  operating  leases,  including  the  two  three-year  renewals  of  the 
APEL lease, are as follows:

On  October  12,  2007,  the  Company  entered  into  Amendment  No.  1  (the  Amendment)  to  its  License 
Agreement  dated  February  2,  2006  with  IBt.    The  original  License  Agreement  provided  the  Company 
with  access to  IBt‘s  proprietary  polymer  based  seed encapsulation technology  for  use  in  brachytherapy 
procedures using Cesium-131 in the United States for a fifteen year term.  A payment of $225,000 was 
made on October 12, 2007 pursuant to the Amendment.  As the parties agreed that the ink jet technology 
was  not  viable  for  Cesium-131  seeds,  the  Amendment  eliminated  the  previously  required  royalty 
payments based on net sales revenue, and the parties intend to negotiate terms for future payments by the 
Company  for  polymer  seed  components to  be  purchased from  IBt  at  IBt's  cost  plus a  to-be-determined 
profit  percentage.    No  agreement  has  been  reached  on  these  terms  and  there  is  no  assurance  that  the 
parties will consummate an agreement pursuant to such terms. 

The Company is subject to various local, state, and federal environmental regulations and laws due to the 
isotopes used to produce the Company‘s product.  As part of normal operations, amounts are expended to 
ensure  that  the  Company  is  in  compliance  with  these  laws  and  regulations.    While  there  have  been  no 
reportable incidents or compliance issues, the Company believes that if it relocates its current production 
facilities  then  certain  decommissioning  expenses  will  be  incurred.    An  asset  retirement  obligation  was 
established  in  the  first  quarter  of  fiscal  year  2008  for  the  Company‘s  obligations  at  its  new  production 
facility.    This  asset  retirement  obligation  will  be  for  obligations  to  remove  any  residual  radioactive 
materials and to remove all leasehold improvements. 

The  industry  that  the  Company  operates  in  is  subject  to  product  liability  litigation.    Through  its 
production  and  quality  assurance  procedures,  the  Company  works  to  mitigate  the  risk  of  any  lawsuits 
concerning its product.  The Company also carries product liability insurance to help protect it from this 
risk. 

The Company has no off-balance sheet arrangements. 

Inflation 

Management  does  not  believe  that  the  current  levels  of  inflation  in  the  United  States  have  had  a 
significant  impact  on  the  operations  of  the  Company.    If  current  levels  of  inflation  hold  steady, 
management does not believe future operations will be negatively impacted. 

New Accounting Standards 

In  December  2007,  FASB  issued  SFAS No. 141(R),  Business  Combinations  (―SFAS 141R‖),  which 
replaces  SFAS No. 141,  Business  Combinations  (―SFAS 141‖).    SFAS 141R  applies  to  all  transactions 

41 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
and  other  events  in  which  one  entity  obtains  control  over  one  or  more  other  businesses.    The  standard 
requires the fair value of the purchase price, including the issuance of equity securities, to be determined 
on the acquisition date.  SFAS 141R requires an acquirer to recognize the assets acquired, the liabilities 
assumed,  and  any  noncontrolling  interests  in  the acquiree  at the  acquisition  date,  measured  at their  fair 
values as of that date, with limited exceptions specified in the statement.  SFAS 141R requires acquisition 
costs  to  be  expensed as  incurred  and restructuring  costs to  be  expensed  in periods  after the acquisition 
date.    Earn-outs  and  other  forms  of  contingent  consideration  are  to  be  recorded  at  fair  value  on  the 
acquisition date.  Changes in accounting for deferred tax asset valuation allowances and acquired income 
tax uncertainties after the measurement period will be recognized in earnings rather than as an adjustment 
to the cost of the acquisition.  SFAS 141R generally applies prospectively to business combinations for 
which the acquisition date is on or after the beginning of the first annual reporting period beginning on or 
after  December 15,  2008  with  early  adoption  prohibited.    The  implementation  of  this  standard  did  not 
have a material impact on the Company‘s consolidated financial position or results of operations. 

In  December  2007,  the  FASB  issued  statement  No.  160,  Noncontrolling  Interests  in  Consolidated 
Financial Statements – an amendment of ARB No. 51 (SFAS 160).  The statement requires noncontrolling 
interests or minority interests to be treated as a separate component of equity, not as a liability or other 
item  outside  of  permanent  equity.    Upon  a  loss  of  control,  the  interest  sold,  as  well  as  any  interest 
retained, is required to be measured at fair value, with any gain or loss recognized in earnings.  Based on 
SFAS  160,  assets  and  liablities  will  not  change  for  subsequent  purchase  of  sales  transactions  with 
noncontrolling  interests  as  long  as  control  is  maintained.    Differences  between  the  fair  value  of 
consideration paid or received and the carrying value of noncontrolling interests are to be recognized as 
an adjustment to the parent interest‘s equity.  SFAS 160 is effective for fiscal years beginning on or after 
December 15, 2008 and earlier adoption is prohibited.  The Company is currently evaluating the impact 
that the implementation of SFAS 160 will have with respect to the Company‘s interest in UralDial. 

In February 2007, the FASB issued statement No. 159, The Fair Value Option for Financial Assets and 
Financial Liabilities Including an Amendment of FASB Statement No. 115 (SFAS 159).  The statement 
allows entities to value financial instruments and certain other items at fair value.  The statement provides 
guidance over the election of the fair value option, including the timing of the election and specific items 
eligible  for  the  fair  value  accounting.    Changes  in  fair  values  would  be  recorded  in  earnings.    The 
statement is effective for fiscal years beginning after November 15, 2007.  The Company does not believe 
the adoption of SFAS 159 will have a material effect on its consolidated financial statements. 

In  September  2006,  the  FASB  issued  statement  No. 157,  Fair  Value  Measurements,  (SFAS 157).  
SFAS 157  defines  fair  value,  establishes  a  framework  for  measuring  fair  value  in  accordance  with 
accounting  principles  generally  accepted in  the  United  States,  and  expands  disclosures  about fair  value 
measurements.    SFAS 157  is  effective  for  fiscal  years  beginning  after  November 15,  2007,  with  earlier 
application encouraged.  Any amounts recognized upon adoption as a cumulative effect adjustment will 
be recorded to the opening balance of retained earnings in the year of adoption.  The Company does not 
believe the adoption of SFAS 157 will have a material effect on its consolidated financial statements.

ITEM 9A – CONTROLS AND PROCEDURES 

Disclosure Controls and Procedures 

Under  the  supervision  and  with  the  participation  of our  management,  including  our  principal  executive 
officer  and  principal  financial  officer,  we  conducted  an  evaluation  of  the  design  and  operation  of  our 
disclosure  controls  and  procedures,  as  such  term  is  defined  under  Rules 13a-14(c)  and  15d-14(c) 
promulgated under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), as of June 30, 
2008.    Based  on  that  evaluation,  our  principal  executive  officer  and  our  principal  financial  officer 
concluded that the design and operation of our disclosure controls and procedures were effective in timely 
alerting them to material information required to be included in the Company's periodic reports filed with 
the  SEC  under  the  Exchange  Act.    The  design  of  any  system  of  controls  is  based  in  part  upon  certain 
assumptions  about  the  likelihood  of  future  events,  and  there  can  be  no  assurance  that  any  design  will 
succeed  in  achieving  its  stated  goals  under  all  potential  future  conditions,  regardless  of  how  remote.  
However,  management  believes  that  our  system  of  disclosure  controls  and  procedures  is  designed  to 
provide a reasonable level of assurance that the objectives of the system will be met. 

Management’s Report on Internal Control over Financial Reporting 

Our management is responsible for establishing and maintaining adequate internal control over financial 
reporting, as such term is defined in Rule 13a-15(f) of the Exchange Act.  Under the supervision and with 
the  participation  of  our  management,  including  our  principal  executive  officer  and  principal  financial 
officer,  we  conducted an evaluation  of the  effectiveness of our  internal  control over  financial reporting 
based  on  the  framework  in  Internal  Control  –  Integrated  Framework  issued  by  the  Committee  of 
Sponsoring Organizations of the Treadway Commission.  Based on our evaluation under the framework 
in  Internal  Control  –  Integrated  Framework,  our  management  concluded  that  our  internal  control  over 
financial reporting was effective as of June 30, 2008. 

This  annual  report  does  not  include  an  attestation  report  of  our  registered  public  accounting  firm 
regarding internal control over financial reporting.  Management‘s report was not subject to attestation by 
our  registered  public  accounting  firm  pursuant  to  temporary  rules  of  the  Securities  and  Exchange 
Commission that permit us to provide only management‘s report in this annual report. 

Changes in Internal Control over Financial Reporting 

There have not been any changes in our internal control over financial reporting (as such term is defined 
in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) during the most recent fiscal quarter that have 
materially  affected,  or  are  reasonably  likely  to  materially  affect,  our  internal  control  over  financial 
reporting. 

Limitations on the Effectiveness of Controls 

Our management, including our principal executive officer and principal financial officer, does not expect 
that our disclosure controls and internal controls will prevent all errors and all fraud.  A control system, 
no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the 
objectives of the control system are met.  Further, the design of a control system must reflect the fact that 
there  are  resource  constraints,  and  the  benefits  of  controls  must  be  considered  relative  to  their  costs.  
Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute 
assurance that all control issues and instances of fraud, if any, within the Company have been detected.  
These inherent limitations include the realities that judgments in decision making can be faulty, and that 
breakdowns can occur because of a simple error or mistake.  Additionally, controls can be circumvented 
by the individual acts of some persons, by collusion of two or more people, or by management or board 
override of the control. 

43 

 
  
 
 
 
 
 
 
 
 
 
 
The design of any system of controls also is based in part upon certain assumptions about the likelihood 
of future events, and there can be no assurance that any design will succeed in achieving its stated goals 
under all potential future conditions; over time, controls may become inadequate because of changes in 
conditions, or the degree of compliance with the policies or procedures may deteriorate.  Because of the 
inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and 
not be detected. 

ITEM 9B – OTHER INFORMATION 

There  were  no  items  required  to  be  disclosed in  a report on  Form  8-K  during  the  fourth quarter  of  the 
fiscal year ended June 30, 2008 that have not been already disclosed on a Form 8-K filed with the SEC. 

PART III 

ITEM 10 – DIRECTORS, EXECUTIVE OFFICERS AND CORPORATE GOVERNANCE  

Each  member  of  the  Board  of  Directors  serves  a  one-year  term  and  is  subject  to  reelection  at  the 
Company‘s Annual Meeting of Shareholders held each year. 

Board Committees 

The  Board  has  established  an  Audit  Committee  consisting  of  Thomas  LaVoy  (Chairman),  Robert 
Kauffman,  and  Albert  Smith;  a  Compensation  Committee  consisting  of  Albert  Smith  (Chairman)  and 
Robert  Kauffman;  and  a  Nominating  Committee  consisting  of  Robert  Kauffman  (Chairman),  Thomas 
LaVoy, and Albert Smith.  No other committees have been formed. 

Audit Committee 

The Audit Committee was established on December 8, 2006, the date on which its Charter was adopted.  
The Audit Committee Charter lists the purposes of the Audit Committee as overseeing the accounting and 
financial reporting processes of the Company and audits of the financial statements of the Company and 
providing assistance to the Board of Directors in monitoring (1) the integrity of the Company‘s financial 
statements,  (2)  the  Company‘s  compliance  with  legal  and  regulatory  requirements,  (3)  the  independent 
auditor‘s  qualifications  and  independence,  and  (4)  the  performance  of  the  Company‘s  internal  audit 
function, if any, and independent auditor. 

The Board of Directors has determined that Mr. LaVoy and Mr. Kauffman are each an ―audit committee 
financial  expert‖  as  defined  in  Item  407(d)(5)  of  Regulation  S-K  promulgated  by  the  Securities  and 
Exchange  Commission,  and  each  Audit  Committee  member  is  independent.    The  Board‘s  conclusions 
regarding  the  qualifications  of  Mr. LaVoy  as  an  audit  committee  financial  expert  were  based  on  his 
service as a chief financial officer of a public company, his experience as a certified public accountant 
and his degree in accounting.  The Board‘s conclusions regarding the qualifications of Mr. Kauffman as 
an  audit  committee  financial  expert  were  based  on  his  service  as  a  chief  executive  officer  of  multiple 
public companies, his active supervision of the principal financial and accounting officers of the public 
companies for which he served as chief executive officer, and his M.B.A. in Finance.

2007, the Company achieved its first gross margin and began making quarterly payments to Mr. Bray as 
outlined in the royalty agreement.  The Company recorded royalty expense of $21,219 and $2,161 for the 
years ended June 30, 2008 and 2007, respectively, related to these payments. 

Roger  Girard,  the  Company‘s  former  Chairman  and  CEO,  had  personally  guaranteed  $20,000  of  the 
BFEDD loan, which was funded in December 2004.  In exchange for his personal guaranty, Mr. Girard 
received  5,728  shares  of  common  stock.    As  a  condition  of  his  resignation  in  February  2008,  the 
Company prepaid $20,000 on the BFEDD loan and obtained Mr. Girard‘s release and Mr. Girard in turn 
surrendered  the  5,728  shares  to  the  Company.    As  part  of  his  settlement,  Mr.  Girard  also  surrendered 
30,072 shares of common stock he had received in 2004 for personally guaranteeing a portion of a line of 
credit for the Company. 

Mr.  Girard  and  David  Swanberg,  the  Company‘s  former  Executive  VP  –  Operations,  personally 
guaranteed  a  portion  of  the  HAEIFC  loan.    As  part  of  their  resignations,  the  Company  obtained  their 
releases from these personal guarantees by prepaying $60,000 and $40,000, respectively. 

Mr. Stephen  Boatwright,  a  former  Company  director,  has  been  actively  involved  in  providing  various 
legal services to the Company and IsoRay Medical, Inc. through the law firm of Keller Rohrback, PLC.  
During  the  fiscal  years  ended  June  30,  2008  and  2007,  the  Company  paid  Keller  Rohrback,  PLC 
approximately  $426,000  and  $459,000,  respectively,  for  legal  services.    In  addition,  the  Company  had 
accrued at June 30, 2008 approximately $10,000 in legal fees to be paid.  

Patent and Know-How Royalty License Agreement 

Effective  August  1,  1998,  Pacific  Management  Associates  Corporation  (PMAC)  transferred  its  entire 
right,  title  and  interest  in  an  exclusive  license  agreement  with  Donald  Lawrence  to  IsoRay,  LLC  (a 
predecessor company) in exchange for a membership interest.  The terms of the license agreement require 
the payment of a royalty based on the Net Factory Sales Price, as defined in the agreement, of licensed 
product  sales.    Because  the  licensor‘s  patent  application  was  ultimately  abandoned,  only  a  1%  ―know-
how‖  royalty  based  on  Net  Factory  Sales  Price,  as  defined,  remains  applicable.    To  date,  management 
believes that there have been no product sales incorporating the ―know-how‖ and that therefore no royalty 
is due pursuant to the terms of the agreement.  Management believes that ultimately no royalties should 
be paid under this agreement as there is no intent to use this ―know-how‖ in the future. 

The licensor of the Lawrence ―know-how‖ has disputed management‘s contention that it is not using this 
―know-how‖.    On  September  25,  2007  and  again  on  October  31,  2007,  the  Company  participated  in 
nonbinding  mediation  regarding  this  matter;  however,  no  settlement  was  reached  with  the  Lawrence 
Family Trust.  After additional settlement discussions which ended in April 2008, the parties still failed to 
reach a settlement.  The parties may demand binding arbitration at any time. 

Director Independence 

Using  the  standards  of  the American  Stock  Exchange,  the  Company's  Board  has  determined  that Mr. 
Kauffman,  Mr.  LaVoy,  and  Mr. Smith each  qualify  under  such  standards  as  an  independent  director.  
Mr. Kauffman, Mr. LaVoy and Mr. Smith each meet the American Stock Exchange listing standards for 
independence both as a director and as a member of the Audit Committee, and  Mr. Kauffman and  Mr. 
Smith each meet the American Stock Exchange listing standards for independence both as a director and 
as a member of the Compensation Committee.  No other directors are independent under these standards.  
The  Company  did  not  consider  any  relationship  or  transaction  between  itself  and these  independent 
directors not already disclosed in this report in making this determination. 

ITEM 14 – PRINCIPAL ACCOUNTANT FEES AND SERVICES 

The  Company  paid  or  accrued  the  following  fees  in  each  of  the  prior  two  fiscal  years  to  its  principal

provided  by  our  independent  registered  public  accountants,  DeCoria,  Maichel  &  Teague,  P.S.    In 
accordance  with  this  policy,  each  type  of  audit,  audit-related,  tax  and  other  permitted  service  to  be 
provided by the independent auditors is specifically described and each such service, together with a fee 
level  or  budgeted  amount  for  such  service,  is  pre-approved  by  the  Audit  Committee.    The  Audit 
Committee has delegated authority to its Chairman to pre-approve additional non-audit services (provided 
such  services  are  not  prohibited  by  applicable  law)  up  to  a  pre-established  aggregate  dollar  limit.    All 
services  pre-approved  by  the  Chairman  of  the  Audit  Committee  must  be  presented  at  the  next  Audit 
Committee  meeting  for  review  and  ratification.    All  of  the  services  provided  by  DeCoria,  Maichel  & 
Teague, P.S. described above were approved by our Audit Committee. 

The Company‘s principal accountant, DeCoria, Maichel & Teague P.S., did not engage any other persons 
or firms other than the principal accountant‘s full-time, permanent employees.

Report of Independent Registered Public Accounting Firm 

Board of Directors and Shareholders 
IsoRay, Inc. 
Richland, Washington 

We  have  audited  the  accompanying  consolidated  balance  sheets  of  IsoRay,  Inc.  and  Subsidiaries  (―the 
Company‖)  (see  Note  1)  as  of  June  30,  2008  and  2007,  and  the  related  consolidated  statements  of 
operations,  changes  in  shareholders‘  equity  and  cash  flows  for  the  years  then  ended.  These  financial 
statements  are  the  responsibility  of  the  Company‘s  management.  Our  responsibility  is  to  express  an 
opinion on these financial statements based on our audits. 

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight 
Board (United States). Those standards require that we plan and perform the audit to obtain reasonable 
assurance  about  whether  the  financial  statements  are  free  of  material  misstatement.  An  audit  includes 
examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. 
An  audit  also  includes  assessing  the  accounting  principles  used  and  significant  estimates  made  by 
management, as well as evaluating the overall financial statement presentation. We believe that our audits 
provide a reasonable basis for our opinion. 

In  our  opinion  the  financial  statements  referred  to  above  present  fairly,  in  all  material  respects,  the 
consolidated  financial  position  of  IsoRay,  Inc.  and  Subsidiaries  as  of  June  30,  2008  and  2007,  and  the 
consolidated results of their operations and their cash flows for the years then ended, in conformity with 
accounting principles generally accepted in the United States of America.

IsoRay, Inc. 
Notes to Consolidated Financial Statements 
For the years ended June 30, 2008 and 2007 

1.  Organization 

Century Park Pictures Corporation (Century) was organized under Minnesota law in 1983.  Century had 
no operations during the period from September 30, 1999 through June 30, 2005. 

On  July  28,  2005,  IsoRay  Medical,  Inc.  (Medical)  became  a  wholly-owned  subsidiary  of  Century 
pursuant to a merger.  Century changed its name to IsoRay, Inc. (IsoRay or the Company).  In the merger, 
the Medical stockholders received approximately 82% of the then outstanding securities of the Company. 

Medical, a Delaware corporation, was incorporated effective June 15, 2004 to develop, manufacture and 
sell isotope-based medical products and devices for the treatment of cancer and other malignant diseases.  
Medical is headquartered in Richland, Washington. 

IsoRay International LLC, a Washington limited liability company, was formed on November 27, 2007 to 
serve as an owner in a Russian LLC that will distribute the Company‘s products to the Russian market 
and  also  license  the  Company‘s  technology  for  use  in  manufacturing  Cs-131  brachytherapy  seeds  in 
Russia. 

2. 

Summary of Significant Accounting Policies 

Consolidation 

The accompanying consolidated financial statements include the accounts of the Company and its wholly-
owned subsidiaries (collectively the Company).  All significant intercompany accounts and transactions 
have been eliminated. 

Cash Equivalents 

The  Company  considers  all  highly  liquid  investments  with  maturities  of  three  months  or  less  when 
purchased to be cash equivalents. 

Short-Term Investments 

The  Company  invests  certain  excess  cash  in  marketable  securities  consisting  primarily  of  commercial 
paper,  auction  rate  securities,  and  money  market  funds.    The  Company  classifies  all  debt  securities  as 
―available-for-sale‖  and  records  the  debt  securities  at  fair  value  with  unrealized  gains  and  temporary 
unrealized  losses  included  in  other  comprehensive  income/loss  within  shareholders‘  equity,  if  material.  
Declines  in  fair  values  that  are  considered  other  than  temporary  are  recorded  in  the  Consolidated 
Statements of Operations. 

Accounts Receivable 

Accounts receivable are stated at the amount that management of the Company expects to collect from 
outstanding balances.  Management provides for probable uncollectible amounts through an allowance for 
doubtful  accounts.    Additions  to  the  allowance  for  doubtful  accounts  are  based  on  management‘s 
judgment,  considering  historical  write-offs,  collections  and  current  credit  conditions.    Balances  which 
remain  outstanding  after  management  has  used  reasonable  collection  efforts  are  written  off  through  a 
charge  to  the  allowance  for  doubtful  accounts  and  a  credit  to  the  applicable  accounts  receivable.  
Payments  received  subsequent  to  the  time  that  an  account  is  written  off  are  considered  bad  debt 
recoveries. 

 F-7 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Inventory 

Inventory  is  reported  at  the  lower  of  cost  or  market.    Cost  of  raw  materials  is  determined  using  the 
weighted average method.  Cost of work in process and finished goods is computed using standard cost, 
which approximates actual cost, on a first-in, first-out basis.  As the Company has operated at a gross loss 
throughout  the  past  fiscal  years,  inventories  have  generally  been  recorded  at  market  or  net  realizable 
value. 

Fixed Assets 

Fixed assets are capitalized and carried at the lower of cost or net realizable value.  Normal maintenance 
and repairs are charged to expense as incurred.  When assets are sold or otherwise disposed of, the cost 
and accumulated depreciation are removed from the accounts and any resulting gain or loss is recognized 
in operations.  

Depreciation is computed using the straight-line method over the following estimated useful lives: 

Production equipment 
Office equipment 
Furniture and fixtures 

3 to 7 years 
2 to 5 years 
2 to 5 years 

Leasehold improvements and capital lease assets are amortized over the shorter of the life of the lease or 
the estimated useful life of the asset. 

The  Company  has  adopted  the  provisions  of  Statement  of  Financial  Accounting  Standards (SFAS)  No. 
144, Accounting for the Impairment or Disposal of Long-Lived Assets.  The provisions of SFAS No. 144 
require that  an impairment  loss  be  recognized  when  the  estimated  future  cash  flows  (undiscounted  and 
without interest) expected to result from the use of an asset are less than the carrying amount of the asset.  
Measurement  of  an  impairment  loss  is  based  on  the  estimated  fair  value  of  the  asset  if  the  asset  is 
expected to be held and used. 

Management  of  the  Company  periodically  reviews  the  net carrying  value  of  all  of  its equipment  on  an 
asset  by  asset  basis.    These  reviews  consider  the  net  realizable  value  of  each  asset,  as  measured  in 
accordance with the preceding paragraph, to determine whether an impairment in value has occurred, and 
the need for any asset impairment write-down.  

Although  management  has  made  its best  estimate  of the factors  that  affect the carrying  value  based on 
current  conditions,  it  is  reasonably  possible  that  changes  could  occur  which  could  adversely  affect 
management's estimate of net cash flows expected to be  generated from its assets, and necessitate asset 
impairment write-downs. 

Deferred Financing Costs 

Financing costs related to the acquisition of debt are deferred and amortized over the term of the related 
debt  using  the  effective  interest  method.    Deferred  financing  costs  include  the  fair  value  of  common 
shares  issued  to  certain  shareholders  for  their  guarantee  of  certain  Company  debt  (see  Note  9)  in 
accordance  with  Accounting  Principles  Board  (APB)  Opinion  No.  21,  Interest  on  Receivables  and 
Payables and Emerging Issues Task Force (EITF) Issue No. 95-13, Classification of Debt Issue Costs in 
the Statement of Cash Flows.  The value of the shares issued was the estimated market price of the shares 
as of the date of issuance.  Amortization of deferred financing costs, totaling $30,504 and $178,633 for 
the years ended June 30, 2008 and 2007, respectively, is included in financing expense on the statements 
of operations.

Licenses 

Amortization of licenses is computed using the straight-line method over the estimated economic useful 
lives of the assets.  In fiscal year 2006, the Company entered into an agreement with IBt, SA, a Belgian 
company  (IBt)  to  use  IBt‘s  proprietary  ―Ink  Jet‖  production  process  and  its  proprietary  polymer  seed 
technology for use in brachytherapy procedures using Cesium-131 (Cs-131).  The Company paid license 
fees  of  $225,000  and  $275,000  during  fiscal  years  2008  and  2006,  respectively,  and  is  amortizing  the 
license over the 15-year term of the license agreement. 

In the fourth quarter of fiscal year 2008, the Company reviewed the carrying values of licenses.  Although 
the Company has not currently integrated this technology into its products, management will reevaluate 
the potential of this technology during fiscal year 2009 after the Company has further improved its current 
processes.  Therefore, the Company did not believe that any impairment had occurred to this intangible 
asset. 

Amortization  of  licenses  was  $43,452  and  $23,426  for  the  years  ended  June  30,  2008  and  2007, 
respectively.  Based on the licenses recorded at June 30, 2008, and assuming no subsequent impairment 
of the underlying assets, the annual amortization expense for each fiscal year ending June 30 is expected 
to be as follows:  $47,670 for 2009, $35,354 for 2010, $35,208 for 2011, $35,208 for 2012, $35,208 for 
2013, and $266,998 thereafter. 

Other Assets 

Other  assets,  which  include  deferred  charges  and  patents,  are  stated  at  cost,  less  accumulated 
amortization.    Amortization  of  patents  is  computed  using  the  straight-line  method  over  the  estimated 
economic useful lives of the assets.  The Company periodically reviews the carrying values of patents and 
any impairments are recognized when the expected future operating cash flows to be derived from such 
assets are less than their carrying value. 

Based on the patents and other intangible assets recorded in other assets at June 30, 2008, and assuming 
no subsequent impairment of the underlying assets, the annual amortization expense for each fiscal year 
ending June 30 is expected to be as follows: $7,798 for 2009, $4,353 for 2010, $2,632 for 2011, $2,632 
for 2012, $2,632 for 2013, and $9,560 thereafter. 

Asset Retirement Obligation 

SFAS No. 143, Asset Retirement Obligations, establishes standards for the recognition, measurement and 
disclosure  of  legal  obligations  associated  with  the  costs to  retire long-lived  assets.    Accordingly,  under 
SFAS No. 143, the fair value of the future retirement costs of the Company‘s leased assets are recorded as 
a  liability  on  a  discounted  basis  when  they  are  incurred  and  an  equivalent  amount  is  capitalized  to 
property  and  equipment.    The  initial  recorded  obligation  is  discounted  using  the  Company‘s  credit-
adjusted risk free-rate and is reviewed periodically  for changes in the estimated future costs underlying 
the  obligation.    The  Company  amortizes  the  initial  amount  capitalized  to  property  and  equipment  and 
recognizes  accretion  expense  in  connection  with  the  discounted  liability  over  the  estimated  remaining 
useful life of the leased assets. 

In  fiscal  year  2006,  the  Company  established  an  initial  asset  retirement  obligation  of  $63,040  which 
represented the discounted cost of cleanup that the Company anticipated it would have to incur at the end 
of its equipment and property leases in its old production facility.  This amount was determined based on 
discussions with qualified production personnel and on historical evidence.  During fiscal year 2007, the 
Company reevaluated its obligations based on discussions with the Washington Department of Health and 
determined  that  the  initial  asset  retirement  obligation  should  be  increased  by  an  additional  $56,120.  
During the second quarter of fiscal year 2008, the Company removed all radioactive residuals and tenant 
improvements from its old production facility and returned the facility to the lessor.  The Company had an 
asset retirement obligation of $135,120 accrued for this facility but total costs incurred to decommission 
 F-9 

 
 
 
 
 
 
 
 
 
 
 
the  facility  were  $274,163  resulting  in  an  additional  expense  of  $139,043  that  is  included  in  cost  of 
products sold.  The additional expense  was mainly due to unanticipated construction costs to return the 
facility to its previous state.  The Company originally believed that the lessor would retain many of the 
leasehold improvements in the building, but the lessor instead required their removal. 

In  September  2007,  another  asset  retirement  obligation  of  $473,096  was  established  representing  the 
discounted cost of the Company‘s estimate of the obligations to remove any residual radioactive materials 
and all leasehold improvements at the end of the lease term at its new production facility.  The estimate 
was  developed  by  qualified  production  personnel  and  the  general  contractor  of  the  new  facility.    The 
Company has reviewed the estimate again based on its experience with decommissioning its old facility 
and believes that the original estimate continues to be applicable. 

During the years ended June 30, 2008 and 2007, the asset retirement obligations changed as follows: 

Beginning balance 
New obligation 
Settlement of existing obligation 
Changes in estimates of existing obligation 
Accretion of discount

Because the Company does not expect to incur any expenses related to its asset retirement obligations in 
fiscal year 2009, the entire balance as of June 30, 2008 is classified as a noncurrent liability. 

Financial Instruments 

The Company discloses the fair value of financial instruments, both assets and liabilities, recognized and 
not recognized in the balance sheet, for which it is practicable to estimate the fair value.  The fair value of 
a financial instrument is the amount at which the instrument could be exchanged in a current transaction 
between willing parties, other than a forced liquidation sale. 

The  carrying  amounts  of  financial  instruments,  including  cash  and  cash  equivalents,  short-term 
investments,  accounts  receivable,  accounts  payable,  notes  payable,  and  capital  lease  obligations, 
approximated their fair values at June 30, 2008 and 2007. 

Revenue Recognition 

The  Company  applies  the  provisions  of  SEC  Staff  Accounting  Bulletin  (SAB)  No. 104,  Revenue 
Recognition.  SAB  No. 104,  which  supersedes  SAB  No. 101,  Revenue  Recognition  in  Financial 
Statements,  provides  guidance  on  the  recognition,  presentation  and  disclosure  of  revenue  in  financial 
statements.  SAB No. 104 outlines the basic criteria that must be met to recognize revenue and provides 
guidance for the disclosure of revenue recognition policies.  The Company recognizes revenue related to 
product sales when (i) persuasive evidence of an arrangement exists, (ii) shipment has occurred, (iii) the 
fee is fixed or determinable, and (iv) collectability is reasonably assured. 

Revenue for the fiscal years ended June 30, 2008 and 2007 was derived solely from sales of the Proxcelan 
Cs-131 brachytherapy seed, which is used in the treatment of cancer.  The Company recognizes revenue 
once the product has been shipped to the customer.  Prepayments, if any, received from customers prior to 
the  time  that  products  are  shipped  are  recorded  as  deferred  revenue.  In  these  cases,  when  the  related 
products  are  shipped,  the  amount  recorded  as  deferred  revenue  is  then  recognized  as  revenue.    The 
Company accrues for sales returns and other allowances at the time of shipment.  Although the Company 
does not have an extensive operating history upon which to develop sales returns estimates, we have used

the  expertise  of  our  management  team,  particularly  those  with  extensive  industry  experience  and 
knowledge, to develop a proper methodology. 

Stock-Based Compensation 

The Company measures and recognizes expense for all share-based payments at fair value in accordance 
with  SFAS  No.  123 (Revised  2004),  Share-Based  Payment  (SFAS  No.  123R).   The  Company  uses the 
Black-Scholes option valuation model to estimate fair value for all stock options on the date of grant.  For 
stock options that vest over time, the Company recognizes compensation cost on a straight-line basis over 
the requisite service period for the entire award. 

Research and Development Costs 

Research  and  development  costs,  including  salaries,  research  materials,  administrative  expenses  and 
contractor  fees,  are  charged  to  operations  as  incurred.    The  cost  of  equipment  used  in  research  and 
development activities which has alternative uses is capitalized as part of fixed assets and not treated as 
an expense in the period acquired.  Depreciation of capitalized equipment used to perform research and 
development is classified as research and development expense in the year recognized. 

Advertising and Marketing Costs 

Advertising  costs  are  expensed  as  incurred  except  for  the  cost  of  tradeshows  and  related  marketing 
materials  which  are  deferred  until  the  tradeshow  occurs.    Advertising  and  marketing  costs  expensed 
(including  tradeshows)  were  $598,663  and  $441,196  for  the  years  ended  June  30,  2008  and  2007, 
respectively.  Marketing costs of $15,800 were included in prepaid expenses at June 30, 2008. 

Legal Contingencies 

In the ordinary course of business, the Company is involved in legal proceedings involving contractual 
and employment relationships, product liability claims, patent rights, environmental matters, and a variety 
of  other  matters.    The  Company  is  also  subject  to  various  local,  state,  and  federal  environmental 
regulations  and  laws  due  to  the  isotopes  used  to  produce  the  Company‘s  product.    As  part  of  normal 
operations,  amounts  are  expended  to  ensure  that  the  Company  is  in  compliance  with  these  laws  and 
regulations.  While there have been no reportable incidents or compliance issues, the Company believes 
that if it relocates its current production facilities then certain decommissioning expenses will be incurred 
and has recorded an asset retirement obligation for these expenses. 

The Company records contingent liabilities resulting from asserted and unasserted claims against it, when 
it  is  probable  that  a  liability  has  been  incurred  and  the  amount  of  the  loss  is  reasonably  estimable.  
Estimating probable losses requires analysis of multiple factors, in some cases including judgments about 
the potential actions of third-party claimants and courts.  Therefore, actual losses in any future period are 
inherently uncertain.  Currently, the Company does not believe any probable legal proceedings or claims 
will have a material adverse effect on its financial position or results of operations.  However, if actual or 
estimated probable future losses exceed the Company‘s recorded liability for such claims, it would record 
additional  charges  as  other  expense  during  the  period  in  which  the  actual  loss  or  change  in  estimate 
occurred. 

Income Taxes 

Income  taxes  are  accounted  for  under  the  liability  method.    Under  this  method,  the  Company  provides 
deferred income taxes for temporary differences that will result in taxable or deductible amounts in future 
years based on the reporting of certain costs in different periods for financial statement and income tax 
purposes.    This  method  also  requires  the  recognition  of  future  tax  benefits  such  as  net  operating  loss 
carryforwards, to the extent that realization of such benefits is more likely than not.   Deferred tax assets 
and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in 
 F-11 

 
 
 
 
 
 
 
 
 
 
 
 
which  those  temporary  differences  are  expected  to  be  recovered  or  settled.    The  effect  on  deferred  tax 
assets and liabilities  of  a change  in tax rates is recognized  in  operations  in  the period  that  includes the 
enactment of the change. 

On  July  1,  2007,  the  Company  adopted  Financial  Accounting  Standards  Board  Interpretation  No.  48, 
Accounting  for  Uncertainty  in  Income  Taxes  (FIN  No.  48).    FIN  No.  48  clarifies  the  accounting  for 
uncertainty in income taxes recognized in accordance with SFAS No. 109 Accounting for Income Taxes, 
prescribing a recognition threshold and measurement attribute for the recognition and measurement of a 
tax position taken or expected to be taken in a tax return.  In the course of its assessment, management has 
determined  that  the  Company,  its  subsidiary,  and  its  predecessors  are  subject  to  examination  of  their 
income tax filings in the United States and state jurisdictions for the 2004 through 2007 tax years.  In the 
event that the Company is assessed penalties and or interest, penalties will be charged to other operating 
expense and interest will be charged to interest expense. 

The Company adopted FIN No. 48 using the modified prospective transition method, which requires the 
application  of  the  accounting  standard  as  of  July  1,  2007.    There  was  no  impact  on  the  financial 
statements  as  of  and  for  the  year  ended  June  30,  2008  as  a  result  of  the  adoption  of  FIN  No.  48.    In 
accordance  with  the  modified  prospective  transition  method,  the  financial  statements  for  prior  periods 
have not been restated to reflect, and do not include, the impact of FIN No. 48. 

Income (Loss) Per Common Share 

The  Company  accounts  for  its  income  (loss)  per  common  share  according  to SFAS  No.  128,  Earnings 
Per  Share.    Basic  earnings  per  share  is  calculated  by  dividing  net  income  (loss)  available  to  common 
shareholders  by  the  weighted  average number  of  common  shares  outstanding,  and  does  not include the 
impact  of  any  potentially  dilutive  common  stock  equivalents.    Common  stock  equivalents,  including 
warrants and options to purchase the Company's common stock, are excluded from the calculations when 
their effect is antidilutive.  At June 30, 2008 and 2007, the calculation of diluted weighted average shares 
does not include preferred stock, common stock warrants or options that are potentially convertible into 
common stock as those would be antidilutive due to the Company‘s net loss position. 

Securities that could be dilutive in the future as of June 30, 2008 and 2007 are as follows:

Use of Estimates 

The preparation of financial statements in accordance with accounting principles generally accepted in the 
United States of America requires management of the Company to make estimates and assumptions that 
affect  the  amounts  reported  in  the  financial  statements  and  accompanying  notes.    Accordingly,  actual 
results could differ from those estimates and affect the amounts reported in the financial statements. 

Reclassifications 

Certain amounts in the prior-year financial statements have been reclassified to conform to the current 
year presentation.

Impact of Recently Issued Accounting Pronouncements 

In  December  2007,  FASB  issued  SFAS No. 141(R),  Business  Combinations  (―SFAS 141R‖),  which 
replaces  SFAS No. 141,  Business  Combinations  (―SFAS 141‖).    SFAS 141R  applies  to  all  transactions 
and  other  events  in  which  one  entity  obtains  control  over  one  or  more  other  businesses.    The  standard 
requires the fair value of the purchase price, including the issuance of equity securities, to be determined 
on the acquisition date.  SFAS 141R requires an acquirer to recognize the assets acquired, the liabilities 
assumed,  and  any  noncontrolling  interests  in  the acquiree  at the  acquisition  date,  measured  at their  fair 
values as of that date, with limited exceptions specified in the statement.  SFAS 141R requires acquisition 
costs  to  be  expensed as  incurred  and restructuring  costs to  be  expensed  in periods  after the acquisition 
date.    Earn-outs  and  other  forms  of  contingent  consideration  are  to  be  recorded  at  fair  value  on  the 
acquisition date.  Changes in accounting for deferred tax asset valuation allowances and acquired income 
tax uncertainties after the measurement period will be recognized in earnings rather than as an adjustment 
to the cost of the acquisition.  SFAS 141R generally applies prospectively to business combinations for 
which the acquisition date is on or after the beginning of the first annual reporting period beginning on or 
after  December 15,  2008  with  early  adoption  prohibited.    The  implementation  of  this  standard  did  not 
have a material impact on the Company‘s consolidated financial position or results of operations. 

In  December  2007,  the  FASB  issued  statement  No.  160,  Noncontrolling  Interests  in  Consolidated 
Financial Statements – an amendment of ARB No. 51 (SFAS 160).  The statement requires noncontrolling 
interests or minority interests to be treated as a separate component of equity, not as a liability or other 
item  outside  of  permanent  equity.    Upon  a  loss  of  control,  the  interest  sold,  as  well  as  any  interest 
retained, is required to be measured at fair value, with any gain or loss recognized in earnings.  Based on 
SFAS  160,  assets  and  liablities  will  not  change  for  subsequent  purchase  of  sales  transactions  with 
noncontrolling  interests  as  long  as  control  is  maintained.    Differences  between  the  fair  value  of 
consideration paid or received and the carrying value of noncontrolling interests are to be recognized as 
an adjustment to the parent interest‘s equity.  SFAS 160 is effective for fiscal years beginning on or after 
December 15, 2008 and earlier adoption is prohibited.  The Company is currently evaluating the impact 
that the implementation of SFAS 160 will have with respect to the Company‘s interest in UralDial. 

In February 2007, the FASB issued statement No. 159, The Fair Value Option for Financial Assets and 
Financial Liabilities Including an Amendment of FASB Statement No. 115 (SFAS 159).  The statement 
allows entities to value financial instruments and certain other items at fair value.  The statement provides 
guidance over the election of the fair value option, including the timing of the election and specific items 
eligible  for  the  fair  value  accounting.    Changes  in  fair  values  would  be  recorded  in  earnings.    The 
statement is effective for fiscal years beginning after November 15, 2007.  The Company does not believe 
the adoption of SFAS No. 159 will have a material effect on its consolidated financial statements. 

In  September  2006,  the  FASB  issued  statement  No. 157,  Fair  Value  Measurements  (SFAS 157).  
SFAS 157  defines  fair  value,  establishes  a  framework  for  measuring  fair  value  in  accordance  with 
accounting  principles  generally  accepted in  the  United  States,  and  expands  disclosures  about fair  value 
measurements.    SFAS 157  is  effective  for  fiscal  years  beginning  after  November 15,  2007,  with  earlier 
application encouraged.  Any amounts recognized upon adoption as a cumulative effect adjustment will 
be recorded to the opening balance of retained earnings in the year of adoption.  The Company does not 
believe the adoption of SFAS No. 157 will have a material effect on its consolidated financial statements.

The Company‘s municipal debt securities consist of auction rate securities (ARS) that are generally long-
term  debt  instruments  that  provide  liquidity  through  a  modified  Dutch  auction  process  that  resets  the 
applicable interest rate at predetermined intervals, usually every 28 days.  ARS generally trade at par and 
are  callable  at  par  on  any  interest  payment  date  at  the  option  of  the  issuer.    Interest  received  during  a 
given  period  is  based  upon  the  interest  rate  determined  through  the  auction  process.    Although  these 
securities are issued and rated as long-term bonds, they are priced and traded as short-term instruments 
because  of  the  liquidity  provided  through  the  interest  rate  reset.    This  mechanism  generally  allows 
existing investors to roll over their holdings and continue to own their respective securities or liquidate 
their holdings by selling their securities at par value.  The Company generally invests in these securities 
for short periods of time as part of its cash management program. 

However,  the  uncertainties  in  the  credit  markets  that  began  in  February  2008  have  prevented  the 
Company and other investors from liquidating their holdings by selling their securities at par value as the 
amount of securities submitted for sale at recent ARS auctions has exceeded the market demand.  These 
securities  continue  to  pay  interest  according  to  their  stated  terms.    For  those  securities  that  failed  to 
auction, the Company continues to hold these securities and accrues interest at a higher rate than similar 
securities for which auctions have cleared.  The Company's ARS are all AAA/Aaa rated investments and 
consist  of  various  student loan  portfolios  with  the  vast  majority  of  the  student loans  guaranteed  by  the 
U.S. Government under the Federal Family Education Loan Program.  These securities were valued using 
a model that takes into consideration the financial conditions of the issuer and the bond insurers as well as 
the current illiquidity of the securities.  If the credit ratings of the issuers deteriorate, the Company may 
adjust the carrying value of these investments.  The Company is uncertain as to when the liquidity issues 
relating to these investments will improve. 

None of the ARS investments in our portfolio were backed by sub-prime mortgage loans. 

Although insufficient demand for certain ARS may continue, we anticipate, based on discussions with our 
investment advisors, that liquidity may possibly be realized through the emergence of secondary markets 
in the near term, particularly considering the high default interest rates, high credit ratings, the backing of 
the Federal Family Education Loan Program, and the historically low default rates of these securities.  As 
such, we believe that the primary impact of the failed auctions is reduced liquidity rather than impairment 
of principal.  In the event that we are unable to sell the investments at or above our carrying value, these 
securities may not provide us with a liquid source of cash. 

Unrealized gains and temporary unrealized losses on these securities are recorded in other comprehensive 
income/loss within Shareholders' Equity.  Declines in fair value that are considered other than temporary 
are  recorded  in  the  Consolidated  Statements  of  Operations  in  loss  on  short-term  investments.    The 
Company has recognized the decline in fair value of the ARS as other than temporary and recorded the 
loss in the statement of operations rather than in other comprehensive income as the Company may need 
access to these funds before the uncertainties in the credit markets are fully resolved.

Restricted Cash 

The  Washington  Department  of  Health,  effective  October  2007,  has  required  the  Company  to  provide 
collateral for the decommissioning of its facility.  To satisfy this requirement, the Company funded two 
certificates of deposits (CDs) totaling $172,500 in separate banks.  The CDs both have original maturities 
of three months but are classified as long-term as the Company does not anticipate decommissioning the 
facility  until  the  end  of  the  current  lease  plus  the  lease  option  periods.    Interest  earned  on  the  CDs  is 
rolled-over at the maturity of each CD and becomes part of the restricted cash balance.  Interest earned

The total value of the stock options awards is expensed ratably over the service period of the employees 
receiving the awards.  As of June 30, 2008, total unrecognized compensation cost related to stock-based 
options and awards was $496,868 and the related weighted-average period over which it is expected to be 
recognized is approximately 0.75 years. 

The Company currently provides share-based compensation under three equity incentive plans approved 
by  the  Board  of  Directors:  the  Amended  and  Restated  2005  Stock  Option  Plan  (the  Option  Plan),  the 
Amended and Restated 2005 Employee Stock Option Plan (the Employee Plan), and the  2006 Director 
Stock Option Plan (the Director Plan).  The Option Plan allows the Board of Directors to grant options to 
purchase  up  to  1,800,000  shares  of  common  stock  to  directors,  officers,  key  employees  and  service 
providers  of  the  Company.    The  Employee  Plan  allows  the  Board  of  Directors  to  grant  options  to 
purchase up to 2,000,000 shares of common stock to officers and key employees of the Company.  The 
Director  Plan  allows  the  Board  of  Directors  to  grant  options  to  purchase  up  to  1,000,000  shares  of 
common  stock  to  directors  of  the  Company.    Options  granted  under  all  of  the  plans  have  a  ten  year

maximum term, an exercise price equal to at least the fair market value of the Company‘s common stock 
on the date of the grant, and varying vesting periods as determined by the Board.  For stock options with 
graded  vesting  terms,  the  Company  recognizes  compensation  cost  on  a  straight-line  basis  over  the 
requisite service period for the entire award. 

On  January  8,  2008,  the  Board  of  Directors  unanimously  adopted,  subject  to  shareholder  approval,  the 
2008 Employee Stock Option Plan (2008 Option Plan).  The 2008 Option Plan would have allowed the 
Board  of  Directors  to  grant  options  to  purchase  up  to  2,000,000  shares  of  common  stock  to  selected 
employees,  consultants,  and  advisors  of  the  Company.    Shareholder  approval  was  not  obtained  for  the 
2008 Plan at the Company‘s annual meeting held on February 20, 2008, and thus no grants have been or 
will be made under the 2008 Option Plan. 

On June 1, 2007, the Company issued an option grant to employees and directors.  The options had an 
exercise price of $4.14 which was the closing market price of the Company‘s stock on the grant date.  The 
options  issued  to  the  employees  vest  over  three  years  while  the  options  granted  to  the  non-employee 
directors were immediately vested. 

The Company‘s former CEO, who also served as Chairman of the Board, was granted 150,000 options, 
and  the  former  Executive  Vice  President  Operations  (EVP–Operations),  who  also  served  as  a  director, 
was granted 100,000 options, and all non-employee directors were granted 50,000 options each.  On July 
25,  2007,  the  Board  discussed  the  issue  of  director  compensation  and  each  director  (including  the 
employee  directors)  elected  to  cancel  50,000  of  their  options  from  the  June  1,  2007  grant.    After  the 
cancellation, the former CEO and former EVP–Operations had 100,000 and 50,000 options, respectively, 
and the non-employee directors had no options from the June 1, 2007 grant.  The terms of these remaining 
options for the former CEO and former EVP–Operations were not changed as part of the cancellation. 

In  accordance  with  SFAS  123R,  all  of  the  options  that  were  cancelled  have  been  accounted  for  as 
cancellation  of  options  with  no  consideration.    No  additional  compensation  cost  associated  with  the 
former  CEO‘s  and  EVP–Operations‘  options  will  be  recognized  after  the  cancellation  date  of  July  25, 
2007.  Cancelled options that had been granted to non-employee directors were immediately vested on the 
date of grant; therefore all related compensation cost was recognized in fiscal year 2007.  Under SFAS 
123R, the value of the cancelled options to each non-employee director was $128,500. 

All of these subsequently cancelled options are included in the options granted and outstanding as of June 
30, 2007 and are included in the options cancelled in fiscal year 2008. 

A summary of stock option activity within the Company‘s share-based compensation plans for the year 
ended June 30, 2008 is as follows:

Black-Scholes valuation model to calculate the fair value are as follows for the year ended June 30, 2008 
and 2007:

The Black-Scholes option valuation model was developed for use in estimating the fair value of traded 
options which have no vesting restrictions and are fully transferable.  In addition, option valuation models 
require the input of highly subjective assumptions, including the expected stock price volatility.  Because 
changes in the subjective input assumptions can materially affect the fair value estimate, in management‘s 
opinion, the existing models do not necessarily provide a reliable single measure of the fair value of its 
employee stock options.  The risk-free interest rate is based on the U.S. treasury security rate in effect as 
of  the  date  of  grant.    The  expected  option  lives,  volatility,  and  forfeiture  assumptions  are  based  on 
historical data of the Company. 

12.  Shareholders’ Equity 

The authorized capital structure of the Company consists of $.001 par value preferred stock and $.001 par 
value common stock. 

Preferred Stock 

The  Company's  Certificate  of  Incorporation  authorizes  6,000,000  shares  of  $0.001  par  value  preferred 
stock available for issuance with such rights and preferences, including liquidation, dividend, conversion, 
and voting rights, as described below. 

Series A 

Series A preferred shares are entitled to a 10% dividend annually on the stated par value per share.  
These shares are convertible into shares of common stock at the rate of one share of common stock 
for  each  share  of  Series  A  preferred  stock,  and  are  subject  to  automatic  conversion  into  common 
stock  upon  the  closing  of  an  underwritten  public  offering  pursuant  to  an  effective  registration 
statement under the Securities Act of 1933 covering the offer and sale of common stock in which the 
gross proceeds to the Company are at least $4 million.  Series A preferred shareholders have voting 
rights  equal  to  the  voting  rights  of  common  stock,  except  that  the  vote  or  written  consent  of  a 
majority of the outstanding preferred shares is required for any changes to the Company‘s Certificate 
of  Incorporation,  Bylaws  or  Certificate  of  Designation,  or  for  any  bankruptcy,  insolvency, 
dissolution or liquidation of the Company.  Upon liquidation of the Company, the Company‘s assets 
are first distributed ratably to the Series A preferred shareholders.  At June 30, 2008, there were no 
Series A preferred shares outstanding. 

Series B 

Series B preferred shares are entitled to a cumulative 15% dividend annually on the stated par value 
per  share.    These  shares  are  convertible  into  shares  of  common  stock  at  the  rate  of  one  share  of 
common stock for each share of Series B preferred stock, and are subject to automatic conversion 
into  common  stock  upon  the  closing  of  an  underwritten  public  offering  pursuant  to  an  effective 
registration statement under the Securities Act of 1933 covering the offer and sale of common stock 
in which the gross proceeds to the Company are at least $4 million.  Series B preferred shareholders

have voting rights equal to the voting rights of common stock, except that the vote or written consent 
of  a  majority  of  the  outstanding  preferred  shares  is  required  for  any  changes  to  the  Company‘s 
Certificate of Incorporation, Bylaws or Certificate of Designation, or for any bankruptcy, insolvency, 
dissolution or liquidation of the Company.  Upon liquidation of the Company, the Company‘s assets 
are  first  distributed  ratably  to  the  Series  A  preferred  shareholders,  then  to  the  Series  B  preferred 
shareholders. 

On February 1, 2007, the Board of Directors declared a dividend on the Series B Preferred Stock of 
all  outstanding  and  cumulative  dividends  through  December  31,  2006.    The  total  dividends  of 
$38,458  were  paid  on  February  15,  2007.    The  Company  does  not  anticipate  paying  any  cash 
dividends on the Series B Preferred Stock in the foreseeable future.  At June 30, 2008, there were 
59,065 Series B preferred shares outstanding and cumulative dividends in arrears were $15,933. 

In  addition  to  the  previously  outstanding  shares  of  common  stock  and  Series  B  preferred  stock,  the 
Company had the following transactions that affected shareholders‘ equity during the years ended June 
30, 2008 and 2007. 

Cancellation of Common Shares 

In  March  2008,  the  Company  cancelled  148,112  shares  of  common  stock  held  by  Roger  Girard,  the 
Company‘s former CEO, due to the release of Mr. Girard from certain personal guarantees of Company 
debt and due to Mr. Girard‘s resignation as Chairman, President, and CEO.  The shares were originally 
issued  in connection  with Mr.  Girard‘s personal  guarantee  of  Company  debt  or  were  contingent  on  his 
employment through August 2008. 

March 2007 Public Equity Offering 

On March 20, 2007, the Company entered into definitive securities purchase agreements (the March 2007 
Purchase Agreements) with certain institutional investors pursuant to which the Company agreed to issue 
and  sell  an  aggregate  of  4,130,500 shares  of  its common  stock  at $4.00 per  share,  through  a registered 
direct offering, for aggregate gross proceeds of approximately $16,522,000, before deducting estimated 
fees and expenses associated with the offering (the Offering).  As part of the Offering, each purchaser of 
five  shares of common stock received a warrant to purchase  one share of common stock at an exercise 
price of $5.00 per share with a four-year term.  A total of 826,100 warrants were issued under these terms.  
The closing took place on March 22, 2007.  The shares of common stock offered by the Company in this 
transaction  were  registered  under  the  Company‘s  existing  shelf  registration  statement  (File  No. 333-
140246)  on  Form  S-3,  which  was  declared  effective  by  the  Securities  and  Exchange  Commission  on 
February 15, 2007, and the prospectus supplement dated March 21, 2007. 

Punk, Ziegel & Company,  L.P. and Maxim Group LLC (the Placement Agents) acted as the placement 
agents  for  the  Offering.    On  March  14,  2007  and  February  2,  2006,  the  Company  executed  placement 
agent agreements (the Placement Agent Agreements) by and between the Company and Punk, Ziegel & 
Company,  L.P.  and  Maxim  Group  LLC,  respectively.    The  Company  paid  the  Placement  Agents  an 
aggregate fee equal to 6% of the gross proceeds of the Offering or approximately $991,000.  In addition, 
the Placement Agents also received 206,526 warrants with an exercise price of $4.40 per share and a five-
year term as part of their overall fee. 

The  warrants  issued  in  the  March  2007  Purchase  Agreements  were  not  accounted  for  as  derivatives  in 
accordance SFAS 133 paragraph 11(a), SFAS 150, and EITF 00-19. 

March 2007 Warrant Call 

As part of the August 2006 Stock Purchase Agreement, the Company issued warrants with an exercise 
price of $3.00 per share.  The warrants were callable by the Company for 45 days after a period of 60

trading days in which the closing price of the underlying stock was at or above $4.50 per share for 30 of 
the 60 days. 

As  of  February  16,  2007,  the  Company‘s  common  stock  had  traded  at  or  above  $4.50  for  30  of  the 
previous  60  days.    On  February  21,  2007,  the  Company  sent  out  notices  to  the  warrant  holders 
establishing a call date of March 26, 2007.  The warrant holders  had the option  to either exercise their 
warrants or permit the Company to repurchase the warrants for $.01 per share on the call date.  All of the 
remaining warrants were exercised prior to the call date.

August 2006 Stock Purchase Agreement 

On  August  17,  2006,  the  Company  sold  certain  shares  of  its  common  stock  and  warrants  to  purchase 
common  stock  pursuant  to  a  Common  Stock  and  Warrant  Purchase  Agreement  (the  August  2006 
Purchase  Agreement)  dated  August  9,  2006.    The  securities  were  issued  to  25  accredited  investors 
pursuant to  the exemption from  registration  provided by  Section  4(2)  of the  Securities  Act  of  1933,  as 
amended.  MicroCapital, LLC acted as the lead investor for the transaction.  Net proceeds of $4.7 million 
were received by the  Company in exchange for the issuance of 2,063,000 shares of common stock and 
warrants to purchase 2,063,000 shares of common stock.  In addition, brokers assisting the Company with 
the capital raise were issued warrants to purchase 206,300 shares of common stock on identical terms as 
the warrants issued to investors. 

Pursuant  to  the  August  2006  Purchase  Agreement,  the  purchase  price  per  share  of  the  Company‘s 
common stock was $2.50, and the accompanying warrants were issued with an exercise price of $3.00 per 
share.    The  warrants  and  the  August  2006  Purchase  Agreement  contained  anti-dilution  provisions, 
including one providing that, if the  Company issues stock or rights to acquire stock at a price less than 
$2.00  (excluding  certain  issuances  such  as  options  to  employees,  directors  and  certain  consultants  and 
shares issued in connection with licensing or leasing transactions), the  Company is required to issue to 
each investor additional shares equal to 25% of what such investor purchased in the original transaction.  
The  warrants  were  exercisable  by  the  holder  (subject  to  anti-dilution  and  adjustment  provisions)  for  a 
period of five years from the date of issuance.  The warrants were callable by the Company for 45 days 
after a period of 60 trading days in which the price of the underlying stock exceeds $4.50 per share for 30 
of the 60 days, and only if a registration statement covering the underlying shares is effective. 

In connection with the August 2006 Purchase Agreement, the Company also entered into a Registration 
Rights Agreement whereby the Company agreed to file a registration statement to cover the re-sale of the 
shares of common stock sold and issuable upon exercise of the warrants.  Under the Registration Rights 
Agreement, the Company agreed to file the registration statement within 60 days of the closing, cure any 
defect  causing  the  registration  statement  to  fail  to  be  effective  within  ten  business  days,  and  cause 
suspension periods for the registration statement to not exceed 60 days in any 360 day period.  A Form 
SB-2  Registration  Statement  to  register  these  shares  was  filed  with  the  SEC  on  October  16,  2006  and 
declared effective on December 5, 2006. 

The  warrants  issued  in  the  August  2006  Purchase  Agreement  were  not  accounted  for  as  derivatives  in 
accordance SFAS 133 paragraph 11(a), SFAS 150, and EITF 00-19. 

Warrants to Purchase Series B Preferred Stock 

Pursuant  to  a  private  placement  of  debt  units  during  2003  and  2004,  a  predecessor  company  issued 
$365,000 of notes payable to investors and granted warrants for the purchase of 227,750 of its Class A 
member  shares.    Through  a  series  of  mergers, these warrants  were exchanged  for  warrants to  purchase 
323,830 Series B preferred shares.  The warrants activity is summarized as follows:

(b)  During  fiscal  year  2007,  one  preferred  warrant  holder  requested  the  Board  of  Directors  to 
extend  the  expiration  date  of  his  warrants  and  to  convert  them  to  common  warrants.    The 
Board granted this request and set new expiration dates as noted below.  The exercise price 
was not changed.  The change in expiration date and the conversion to common warrants was 
a modification of the original warrant based on market conditions and was accounted for as a 
financing transaction similar to a modification of the offering price of shares in a stock sale.  
Therefore there was no effect on the statement of operations as the Company had previously 
determined  that  under  SFAS  133  and  EITF  00-19  these  warrants  were  equity  instruments 
rather than derivatives.  These converted common warrants are summarized as follows:

Board granted this request and set new expiration dates as noted in the Warrants to Purchase 
Series B Preferred Stock section of this footnote. 

On January 8, 2008, the Board of Directors retroactively extended the expiration dates of warrants issued 
pursuant  to  the  Company‘s  private  placement  memorandums  dated  October  17,  2005  and  February  1, 
2006 for an additional one-year period.  These warrants began expiring in October 2007.  Based on the 
extension,  the  warrants  will  now  expire  between  October  2008  and  February  2009.    No  other  terms  or 
conditions of the warrants were changed.  The change in expiration dates affected outstanding warrants to 
purchase  2,102,142  shares  of  common  stock.    Of  these  outstanding  warrants,  there  were  warrants  to 
purchase 18,000 common shares held by two directors of the Company.  Prior to the extension, warrants 
to purchase 1,186,219 shares of common stock had passed their original expiration dates.

13.  Treasury Stock 

In June 2008, the Board of Directors of IsoRay authorized the repurchase of up to 1,000,000 shares of the 
Company‘s  common  stock.    During  June  2008,  the  Company  repurchased  5,000  shares  of  its  common 
stock for $3,655. 

14. 

Income Taxes 

The Company recorded no income tax provision or benefit for the years ended June 30, 2008 and 2007. 

The Company had a net deferred tax asset of approximately $9.3 and $6.7 million as of June 30, 2008 and 
2007, respectively.  The deferred tax asset has arisen principally from net operating loss carryforwards, 
share-based compensation, depreciation and amortization, and accrued compensation.  The deferred tax 
asset was calculated based on the currently enacted 34% statutory income tax rate.  Since management of 
the Company cannot determine if it is more likely than not that the Company will realize the benefit of its 
net deferred tax asset, a valuation allowance equal to the full amount of the net deferred tax asset at June 
30, 2008 and 2007 has been established. 

At  June  30,  2008,  the  Company  had  tax  basis  net  operating  loss  carryforwards  of  approximately  $27 
million available to offset future regular taxable income.  These net operating loss carryforwards expire 
through 2028. 

15.  401(k) and Profit Sharing Plan 

The  Company  has  a  401(k)  plan,  which  commenced  in  fiscal  year  2007,  covering  all  eligible  full-time 
employees  of  the  Company.    Contributions  to  the  401(k)  plan  are  made  by  the  participants  to  their 
individual  accounts  through  payroll  withholding.    The  401(k)  plan  also  allows  the  Company  to  make 
contributions at the discretion of management.  To date, the Company has not made any contributions to 
the 401(k) plan. 

16.  Related Party Transactions 

The  Company  received  various  legal  services  for  assistance  with  the  common  stock  and  warrant 
offerings, lease and contract review, and other general counsel support from a law firm in which one of 
the firm‘s partners was formerly a member of the Company‘s Board of Directors (until his resignation in 
February 2008).  The total amounts paid in 2008 and 2007 to the law firm were $426,430 and $458,534, 
respectively.    The  2008  amount  includes  approximately  $10,000  accrued  in  accounts  payable  as  of      
June 30, 2008.

UralDial, LLC 

On  January  23,  2008,  the  Company,  through  its  subsidiary  IsoRay  International  LLC,  became  a  30% 
owner  in  a  Russian  limited  liability  company,  UralDial,  LLC  (UralDial),  a  new  company  based  in 
Yekaterinburg,  Russia.    The  Company  is  currently  working  on  a  distribution  agreement  with  UralDial 
through  which  the  Company  will  sell  its  Proxcelan  Cs-131  brachytherapy  seeds  to  UralDial  for 
distribution  to  medical  centers  in  Russia.    From  its  formation  through  June  30,  2008,  UralDial  did  not 
have any significant activity and does not have any significant assets or liabilities. 

18.  Commitments and Contingencies 

Royalty Agreement for Invention and Patent Application 

A shareholder of the Company previously assigned his rights, title and interest in an invention to IsoRay 
Products  LLC  (a  predecessor  company)  in  exchange  for  a  royalty  equal  to  1%  of  the  Gross  Profit,  as 
defined,  from  the  sale  of  ―seeds‖  incorporating  the  technology.    The  patent  and  associated  royalty 
obligations were transferred to the Company in connection with the merger transaction (see Note 1). 

The Company must also pay a royalty of 2% of Gross Sales, as defined, for any sub-assignments of the 
aforesaid  patented  process  to  any  third  parties.    The  royalty  agreement  will  remain  in  force  until  the 
expiration  of  the  patents  on  the  assigned  technology,  unless  earlier  terminated  in  accordance  with  the 
terms of the underlying agreement. 

During  fiscal  years  2008  and  2007,  the  Company  recorded  royalty  expenses  of  $21,219  and  $2,161, 
respectively. 

Patent and Know-How Royalty License Agreement 

IsoRay Products LLC was the holder of an exclusive license with Donald Lawrence to use certain ―know-
how.‖  This license was transferred to Medical and subsequently to the Company in connection with the 
merger transaction (see Note 1).  The terms of the original license agreement required the payment of a 
royalty  based  on  the  Net  Factory  Sales  Price,  as  defined  in  the  agreement,  of  licensed  product  sales.  
Because  the  licensor‘s  patent  application  was  ultimately  abandoned,  only  a  1%  ―know-how‖  royalty 
based on Net Factory Sales Price, as defined, remains applicable. To date, management believes that there 
have been no product sales incorporating the ―know-how‖ and that therefore no royalty is due pursuant to 
the terms of the agreement.  Management believes that ultimately no royalties should be paid under this 
agreement as there is no intent to use this ―know-how‖ in the future. 

The licensor of the Lawrence ―know-how‖ has disputed management‘s contention that it is not using this 
―know-how‖.    On  September  25,  2007  and  again  on  October  31,  2007,  the  Company  participated  in 
nonbinding  mediation  regarding  this  matter;  however,  no  settlement  was  reached  with  the  Lawrence 
Family  Trust.    After  additional  settlement  discussions,  which  ended  in  April  2008,  the  parties  failed to 
reach a settlement.  The parties may demand binding arbitration at any time.  

Battelle Memorial Institute Production Agreement 

In April 2004, IsoRay Products LLC entered into an agreement with Battelle Memorial Institute, Pacific 
Northwest  Division  (Battelle),  the  operator  of  the  Pacific  Northwest  National  Laboratory,  for  certain 
production-related services and facilities.  This agreement was assumed by Medical and subsequently by 
the  Company  following  the  merger  transaction  (see  Note  1).    In  accordance  with  the  terms  of  the 
agreement, the Company is required to make advance payments, which are then applied against billings 
by  Battelle  as  services  are  provided.    During  the  years  ended  June  30,  2008  and  2007,  the  Company 
incurred  $142,991  and  $151,065,  respectively,  of  costs  for  production-related  services  and  facilities 
provided  by  Battelle.    At  June  30,  2008,  prepaid  expenses  included  $60,107  related  to  this  agreement.

The agreement, which expires December 31, 2008, may be terminated at any time by either party, upon 
giving a 60-day written notice to the other party. 

Operating Lease Agreements 

The  Company  leases  office  and  laboratory  space  and  production  and  office  equipment  under 
noncancelable  operating  leases.    The  lease  agreements  require  monthly  lease  payments  and  expire  on 
various dates through April 2016 (including renewal dates).  The Company‘s significant lease is described 
below. 

On  May  2,  2007,  Medical  entered  into  a  lease  for  its  new  production  facility  with  Energy  Northwest,  the 
owner of the Applied Process Engineering Laboratory (the APEL lease).  The new lease originally provided 
the Company with 19,328 square feet of manufacturing and office space and the Company has moved all 
manufacturing operations to this new leased space as of September 2007 and vacated its leased space at the 
PEcoS-IsoRay Radioisotope Laboratory (PIRL).  The APEL lease has a three year term expiring on April 
30, 2010, plus options to renew for two additional three-year terms, and monthly rent of approximately 
$26,700, subject to annual increases based on the Consumer Price Index, plus monthly janitorial expenses 
of approximately $700.  Due to the severe economic penalty associated with not exercising the two lease 
renewal options, the Company currently intends to exercise both of the three-year renewal options at the 
appropriate time in the lease.  Subsequent to the initial signing of this lease, the Company reconfigured its 
space requirements and returned some lab space to Energy Northwest.  This has reduced the Company‘s 
rent  to  approximately  $24,200  per  month  plus  monthly  janitorial  expenses  of  approximately  $550  per 
month. 

On  October  10,  2007,  the  Company  executed  a  Lease  Agreement  with  Perma-Fix  Northwest  Richland, 
Inc. (Perma-Fix).  The Lease Agreement had an effective date of September 1, 2007, and provided for the 
continuation  of  the  Company's  lease  of  its  PIRL  facility  located  at  2025  Battelle  Boulevard,  Richland, 
Washington.   The  Company  originally  leased  this  facility  from  Nuvotec  USA,  Inc.  under  a  Lease 
Agreement dated February 9, 2005, but Nuvotec USA, Inc. subsequently sold the facility to Perma-Fix.  
The new lease term was through January 31, 2008, with early termination permitted upon 45 days prior 
written notice.  The Company terminated this lease in mid-December 2007. 

Future  minimum  lease  payments  under  operating  leases  including  the  two  three-year  renewals  of  the 
APEL lease, which the Company intends to exercise, are as follows: 

Year ending June 30, 
2009

Rental  expense  amounted  to  $354,202  and  $207,044  for  the  years  ended  June  30,  2008  and  2007, 
respectively. 

License Agreement with IBt 

In February 2006, the Company signed a license agreement with International Brachytherapy SA (IBt), a 
Belgian  company,  covering  North  America  and  providing  the  Company  with  access  to  IBt‘s  Ink  Jet 
production process and its proprietary polymer seed technology for use in brachytherapy procedures using 
Cs-131.    Under  the  original  agreement  royalty  payments  were  to  be  paid  on  net  sales  revenue 
incorporating the technology.

On  October  12,  2007,  the  Company  entered  into  Amendment  No.  1  (the  Amendment)  to  its  License 
Agreement  dated  February  2,  2006  with  IBt.    The  Company  paid  license  fees  of  $275,000  (under  the 
original  agreement)  and  $225,000  (under  the  Amendment)  during  fiscal  years  2006  and  2008, 
respectively.    The  Amendment  eliminates  the  previously  required  royalty  payments  based  on  net  sales 
revenue, and the parties intend to negotiate terms for future payments by the Company for polymer seed 
components to be purchased at IBt's cost plus a to-be-determined profit percentage.  No agreement has 
been  reached  on  these  terms  and  there  is  no  assurance  that  the  parties  will  consummate  an  agreement 
pursuant to such terms. 

19.  Concentrations of Credit and Other Risks 

Financial Instruments 

The Company‘s financial instruments that are exposed to concentrations of credit risk consist primarily of 
cash and cash equivalents, short-term investments, and accounts receivable. 

The  Company‘s  cash  and  cash  equivalents  are  maintained  with  high-quality  financial  institutions.    The 
accounts  are  guaranteed  by  the  Federal  Deposit  Insurance  Corporation  (FDIC)  up  to  $100,000.    At      
June 30, 2008, uninsured cash balances totaled approximately $4.6 million. 

Short-term investments are held by a major, high-quality financial institution.  Generally, these securities 
are  traded  in  a  highly  liquid  market  and  may  be  redeemed  upon  demand  and  bear  minimal  risk.    As 
discussed  in  Note  3,  the  Company  has  been  unable  to  liquidate  its  municipal  debt  securities  due  to 
uncertainties in the credit markets.  The Company is uncertain as to when the liquidity issues related to 
these investments will improve. 

The  Company‘s  accounts  receivable  result  from  credit  sales  to  customers.    The  Company  had  two 
customers  whose  sales  were  greater  than  10%  for  each  of  the  years  ended  June  30,  2008  and  2007, 
respectively.    These  customers  represented  a  combined  34.3%  and  37.7%  of  the  Company‘s  total 
revenues for the years ended June 30, 2008 and 2007, respectively.  These same customers accounted for 
a  combined  38.4%  and  25.6%  of  the  Company‘s  net  accounts  receivable  balance  at  June 30,  2008  and 
2007, respectively. 

The loss of any of these significant customers would have a temporary adverse effect on the Company‘s 
revenues, which would continue until the Company located new customers to replace them. 

The  Company  routinely  assesses  the  financial  strength  of  its  customers  and  provides  an  allowance  for 
doubtful accounts as necessary. 

Inventories 

Most  components  used  in  the  Company‘s  product  are  purchased  from  outside  sources.    Certain 
components are purchased from single suppliers.  The failure of any such supplier to meet its commitment 
on  schedule  could  have  a  material  adverse  effect  on  the  Company‘s  business,  operating  results  and 
financial condition.  If a sole-source supplier or a supplier of Cs-131 or irradiated barium were to go out 
of  business  or  otherwise  become  unable  to  meet  its  supply  commitments,  the  process  of  locating  and 
qualifying  alternate  sources  could  require  up  to  several  months,  during  which  time  the  Company‘s 
production  could  be  delayed.    Such  delays  could  have  a  material  adverse  effect  on  the  Company‘s 
business, operating results and financial condition.

20.  Subsequent Events 

The following events and transactions have occurred subsequent to June 30, 2008: 

FDA Inspection 

The Company underwent its first inspection by the Food and Drug Administration (FDA) in July 2008.  
The inspection covered the manufacturing and quality systems at its Richland facility.  At the end of the 
inspection, no report of deviations from Good Manufacturing Practices or list of observations (form FDA 
483) was issued to IsoRay. 

Extension of Warrants 

On August 20, 2008, the Board of Directors extended the expiration dates of warrants issued pursuant to 
the  Company‘s  private  placement  memorandums  dated  October  17,  2005  and  February  1,  2006  for  an 
additional  one-year  period.    These  warrants  originally  began  expiring  in  October  2007  but  were 
retroactively  extended  for  a  one-year  term  on  January  8,  2008  (Note  12).    Based  on  this  additional 
extension,  the  warrants  will  now  expire  between  October  2009  and  February  2010.    No  other  terms  or 
conditions of the warrants were changed.  The change in expiration dates affected outstanding warrants to 
purchase  2,102,142  shares  of  common  stock.    Of  these  outstanding  warrants  there  were  warrants  to 
purchase 12,500 shares held by the Chairman and Interim CEO of the Company.
