(cid:190)  Pipeline Overview  

Oncology 

According  to  the  American  Cancer  Society’s 

Cancer  Facts  &  Figures,  cancer  is  the  second 

leading cause of death among Americans and is 

responsible  for  one  of  every  four  deaths  in  the 

United  States.  Close  to  1.5  million  new  cases  are 

expected to be diagnosed in 2008. 

Oncology Drug Candidates 

Rexahn is developing targeted cancer drugs that inhibit cancer cell signal transduction involved 

in cancer cell survival and progression. We are also developing anti-cancer nanomedicines that 

potentially offer significant advantages and treatment benefits over conventional chemotherapy, 

in  cancer  patients  through  improved  target  drug  delivery,  reduced  side  effects,  and  greater 

treatment effectiveness. 

ArchexinTM: AKT-1 inhibitor.  ArchexinTM inhibits AKT-1, which plays a key role in cancer progression 

by  stimulating  cell  proliferation  and  cell  survival,  promoting  angiogenesis  and  being  a 

mechanism  for  drug  resistance.  ArchexinTM  is  the  first  drug  that  is  able  to  inhibit  both  activated 

and native AKT-1. Phase I clinical trials demonstrated that grade 3 (G3) fatigue was the only dose 

limiting  toxicity.  No  significant  hematological  effects  or  other  serious  adverse  events  were 

observed.  Phase  II  clinical  trials  are  ongoing  in  patients  with  advanced  and  relapsed  renal  cell 

carcinoma. 

RX-0047-Nano: HIF-1 Transcription Factor Inhibitor.  RX-0047-Nano is a first-in-class, nanoliposomal 

cancer  drug  that  selectively  inhibits  expression  of  the  HIF-1  transcription  factor.  HIF-1  is  a  key 

signaling  molecule  in  angiogenesis,  cancer  cell  survival  and  invasion,  and  radiation  resistance. 

HIF-1 is over-expressed in several human cancers, which is related to the increased mortality. RX-

0047-Nano  is  expected  to  provide  significant  clinical  benefits  including  improved  efficacy, 

extended circulation time and reduced drug-related toxicity. Phase I trials are planned for 2009. 

Nano-polymer  Anticancer  Drugs.  A  major  problem  with  many  cancer  drugs  is  their  limited 

efficacy,  severe  toxicity  and  drug  resistance.  Rexahn’s  nano-polymer  anti-cancer  drugs  may 

deliver  drugs  more  precisely  to  tumor  tissues  with  less  toxic  effects  and  may  be  able  to  bypass 

multidrug resistance. Phase I trials may be initiated in 2009. 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Neuroscience  

According  to  the  World  Health  Organization  (WHO),  154  million 

cases of depression are reported annually, worldwide. There are 

45  to  55  million  estimated  prevalent  cases  of  major  depressive 

disorder (MDD) in the US, with prevalence rates ranging from 7% 

to 15%. Antidepressant drugs are  the largest  segment of global 

CNS therapeutics sales, forecasted at $18 billion for 2008. 

Neuroscience Drug Candidates 

Our neuroscience compounds are being developed for depression and mood disorders, and to 

work as centrally acting therapeutics for treatment of sexual dysfunction.  

SerdaxinTM.    New,  non-SSRI  drugs  for  depression  and  mood  disorders  are  being  developed. 

SerdaxinTM is a dual enhancer of serotonin and dopamine in the brain, of which neurotransmitters 

are  important  for  both  negative  and  positive  mood  states.  Studies  to  date  indicate  that 

SerdaxinTM does not cause the motor impairment and cognition deficit of benzodiazepines, and 

does not result in insomnia, weight gain, nausea or sexual dysfunction of SSRIs, potentially resulting 

in  greater  medication  compliance.  SerdaxinTM  addresses  most  of  the  highest  unmet  needs  by 

providing potentially faster onset of action, better and broader efficacy and fewer side effects. 

Phase II clinical trials are currently in progress in patients with major depressive disorder. 

ZoraxelTM.    The  drug  is  a  centrally  acting  enhancer  for  treatment  of  erectile  dysfunction  (ED). 

ZoraxelTM significantly improved sexual function (sexual motivation-arousal, erection and release) 

in preclinical models. Unlike PDE-5 inhibitors working at the peripheral blood vessel with numerous 

side  effects,  ZoraxelTM  works  in  the  CNS  and  comes  with  established  safety  in  humans.  Phase  II 

clinical trials are ongoing in patients with erectile dysfunction. 

 
 
 
 
  
 
 
 
 
 
(cid:190)  Letter from the Chairman  

Dear Shareholders: 

In  2007,  Rexahn  continued  significant  advances  toward  its 

goal  of    commercializing  first-in-class  or  market-leading 

therapeutics  for  cancer,  central  nervous  system  disorders, 

and  sexual  dysfunction.    In  particular,  during  the  year,  we 

advanced  multiple  compounds  to  evaluate  safety  and 

efficacy  in  humans,  and  executed  on  regulatory  strategies 

towards  market  approval.    A  great  deal  of  teamwork  and 

strategic planning goes into our work.  While challenges remain, the opportunities to 

serve patients to regain their quality of life and happiness are galvanizing our efforts 

and focus.  

2007 marked the first time we initiated multiple clinical programs.  As such, Rexahn is 

entering  an  exciting  stage  of  its  life  cycle  and  growth,  in  part,  stemming  from  the 

milestones we have achieved with our lead compounds, Archexin™, Serdaxin™ and 

Zoraxel™. ArchexinTM, our flagship drug currently in Phase II clinical trials, is a targeted 

cancer  therapy  with  the  potential  to  deliver  less  toxic,  more  effective,  better-

tolerated  treatment  to  patients  with  solid  tumors.    ArchexinTM  is  unique  from  other 

targeted or cytotoxic cancer drugs in two ways.  First, Archexin™ is the first and only 

inhibitor of both the activated and native forms of Akt, a protein kinase essential for 

tumor  growth  and  progression.    Second,  ArchexinTM  possesses  the  ability  to  impact 

the  drug  resistance  that  is  developed  by  treatment  with  the  targeted  therapies.  

Thus, the development of ArchexinTM could represent a potentially new standard of 

care  for  providing  cancer  patients  with  survival  and  quality  of  life  benefits  over 

today’s existing therapies 

Our lead indication for ArchexinTM is Renal Cell Carcinoma, or RCC - one of the most 

difficult cancers to treat with five-year survival ranging from  0% to 20%.  In addition to 

RCC, multiple indications are possible, including the FDA-designated orphan cancers 

-- stomach, ovarian, pancreas and brain cancers.   

We  are  very  excited  about  the  initiation  this  year  of  Phase  II  clinical  trials  for 

SerdaxinTM  for  treatment  of  major depressive  disease  and  ZoraxelTM  for  treatment  of 

erectile dysfunction this year.  We  will update you on these clinical outcomes, when 

 
 
 
  
 
 
 
 
available.  Both  SerdaxinTM  and  ZoraxelTM  possess  market  leader  potential  in  their 

respective indications.  

Despite  the  worldwide  financial  market  turmoil,  we  have  successfully  completed  a 

corporate  raise  last  year  through  a  private  placement.  The  financing  will  help 

prepare 2008 as very productive year. 

Over  the  past  few  years,  we  have  carried  out  development  of  nano-medicines. 

Nano-medicines  have  the  potential  to  provide  a  pipeline  of  new  therapeutic  tools 

and  technology  platforms  that  could  offer  patients  and  physicians  better  targeted 

cancer therapies with less toxicity. Successful development of these nano-medicines 

will significantly strengthen Rexahn’s pipeline portfolio and future financial status. By 

the end of this year, we expect to own five nano-based anticancer drug candidates.  

In 2008, we also plan Rexahn’s shares to get listed on the American Stock Exchange 

(AMEX)  which  may  afford  the  Company  improved  investor  awareness  and  much 

stronger  financial  future.  I  am  excited  about  the  promising  growth  that  is  already 

underway  at  Rexahn,  and  the  opportunities  to  deliver  new  medicines  that  could 

help  patients  regain  quality  of  life.    I  would  like  to  express  my  gratitude  to  our 

employees,  Board  of  Directors,  partners  and  suppliers  for  their  unselfish  efforts  and 

support of our mission. 

Sincerely, 

Chang H. Ahn, Ph.D.

PART I 

Any  references  to  "we",  "us",  "our,"  the  "Company"  or  "Rexahn"  shall  mean  Rexahn 

Pharmaceuticals, Inc. 

We are a clinical stage biopharmaceutical company dedicated to the discovery, development, and 
commercialization  of  innovative  treatments  for  cancer,  central  nervous  system  (CNS)  disorders,  sexual 
dysfunction  and  other  unmet  medical  needs.    We  develop  therapies  that  make  it  possible  to  regain 
normalcy for patients suffering from disease.  We have three drug candidates  entering Phase II clinical 
trials  this  year  and  four  other  drug  candidates  in  pre-clinical  development.    We  intend  to  leverage  our 
drug-discovery  technologies,  scientific  expertise  and  developmental  know-how  to  develop  and 
commercialize  targeted  cancer  drugs  with  greater  clinical  benefits  for  patients  and  new  drugs  for  the 
treatment of diseases of the central nervous system and sexual dysfunction.  We will continue to identify 
internally developed compounds as potential drug candidates, as well as assess compounds developed by 
others  and,  if  necessary,  license  the  rights  to  these  compounds  in  order  to  develop  and  commercialize 
them as drugs.  For a description of our pipeline drug candidates, see "Our Pipeline Drug Candidates" in 
this Item 1. 

Our  principal  corporate  offices  are  located  at  9620  Medical  Center  Drive,  Rockville, 

Maryland 20850 in Maryland's I-270 technology corridor.  Our telephone number is (240) 268-5300. 

Rexahn is developing targeted cancer drugs and nano-medicines to address unmet needs in cancer 

treatment, and significantly improve quality of life and survival of patients.   

•  Targeted cancer drugs.  Signal transduction is the process of relaying external information 
from  the  surface  of  cells  to  a  specific  internal  response,  such  as  cancer  cell  proliferation. 
Signals  are  conveyed  through  tightly  regulated  communication  networks  and  pathways  that 
consist  of  functionally  diverse  molecules  such  as  protein  kinases,  transcription  factors  and 
their interacting molecules. As understanding of the molecular basis for signal transduction of 
cancer cells continues to increase, the identification of molecular targets and development of 
more targeted therapeutics have evolved.1  

Rexahn  is  developing  targeted  cancer  drugs  that  inhibit  cancer  cell  signal  transduction  and 
block the production of proteins involved in tumor growth and survival. The protein kinase 
Akt,  and  the  transcription  factor  hypoxia-Inducible  Factor-1  alpha  (HIF-1α)  are  key  signal 
proteins important for tumor growth and expansion. Akt is often over-expressed and activated 
in  major  human  solid  tumors,  and  may  contribute  to  cancer  cell  survival,  proliferation, 
metastasis, and resistance.2  HIF-1α plays a vital role in angiogenesis and is overexpressed in 
many  human  cancers,  including  renal  cell  carcinoma,  ovarian,  pancreatic,  and  prostate 
cancers.  HIF-1α  overexpression  is  correlated  with  tumor  growth,  metastasis  and  patient 
mortality.3

•  Cancer Nanomedicines.  Innovative cancer nanomedicines offer significant advantages and 
treatment benefits, including: improved quality of life for cancer patients through improved 
target drug delivery, reduced side effects, and greater treatment effectiveness.  

ArchexinTM, RX-0201-nano and other Rexahn targeted cancer drugs have the potential to address 

key market needs by delivering:  

(1) 

New treatments for relapsed and refractory cancers.  Targeting key signal molecules 
responsible  for  cancer  relapse  with  new  potent  anticancer  drugs  could  significantly  improve  cancer 
treatment outcomes, and inhibit and down-regulate cancer signaling molecules.  

(2) 

Cancer  treatments  that  address  drug  resistance.  Both  Akt  and  HIF-1α  are  closely 
involved  in  cancer  resistance.  The  activation  of  Akt is  a  main  mechanism  for  drug  resistance  of  EGFR 
tyrosine kinase inhibitors (TKIs). TKIs are currently considered a major advance in cancer treatment, but 
once the drug resistance to the TKIs occurs, those drugs are not effective anymore. Therefore, need for a 
drug  like  ArchexinTM  that  inhibits  activated  Akt  is  in  high  demand.4   HIF-1α  is  a  key  mechanism  of 
radiation resistance. Treatment with radiation is sometimes a cure method in cancer treatment, therefore, 
resistance;  therefore,  direct  inhibition  of  HIF-1  may  address  radiation  resistance  and  lead  to  better 
treatment outcomes. 

(3) 

Less toxic and more  effective cancer drugs. Increased selectivity for a growing range 
of cancer molecular targets offers the opportunity to commercialize more effective and less toxic cancer 
treatments.5  

We  currently  have  a  number  of  drug  candidates  in  clinical  development.  Our  lead  anti-cancer 
drug  candidate,  Archexin™,  which  we  previously  referred  to  as  RX-0201,  completed  Phase  I  clinical 
trials in 2006 and is currently in Phase II clinical trials for patients with renal cell carcinoma (RCC), an 
abnormal  growth  of  cells  lining  the  tubules  of  the  kidney.    Archexin™  received  "orphan  drug" 
designation  from  the  U.S.  Food  and  Drug  Administration,  or  FDA,  for  five  cancer  indications  (RCC, 
glioblastoma, ovarian cancer, stomach cancer and pancreatic cancer).  The FDA orphan drug program is 
intended  to  stimulate  research,  development  and  approval  of  products  that  treat  rare  diseases.    With 
orphan drug designation, sponsor companies benefit from an expedited FDA review or approval process, 
seven years of marketing exclusivity after approval and tax incentives for clinical research. 

Rexahn  is  currently  developing  SerdaxinTM  for  treatment  of  depression,  and  ZoraxelTM  for 
treatment of sexual dysfunction. ZoraxelTM is in Phase II clinical trials in male erectile dysfunction and is 
a  dual  enhancer  of  serotonin  and  dopamine  that  are  key  brain  neurotransmitters  important  for  sexual 
function such as sexual arousal, erection and ejaculation. Phase II clinical trials for SerdaxinTM are also 
planned in 2008. Further, Rexahn leverages its proprietary nanomedicine research and multi-target aimed 
ligands  platform  to  strengthen  its  pre-clinical  pipeline,  and  develop  cancer  drugs  that  offer  greater 
therapeutic benefits and quality of life for patients.

Company Background 

Our company resulted from a merger of Corporate Road Show.Com Inc., originally a New York 
corporation  ("CPRD"),  and  Rexahn,  Corp,  a  Maryland  corporation  immediately  after  giving  effect  to 
a 1-for-100  reverse  stock  split  and  the  reincorporation  of  CPRD  as  a  Delaware  corporation  under  the 
name  "Rexahn  Pharmaceuticals,  Inc."  ("Rexahn  Pharmaceuticals"),  with  Rexahn,  Corp  surviving  as  a 
wholly  owned  operating  subsidiary  of  ours  (the  "Merger").    The  Merger  was  effective  as  of  May 13, 
2005.  On September 29, 2005, Rexahn, Corp, was merged with and into us and Rexahn, Corp's separate 
existence was terminated. 

Rexahn, Corp was founded in March 2001 and began as a biopharmaceutical company focusing 
on  oncology  drugs.    Dr.  Chang  Ahn,  our  Chairman,  a  former  Food  and  Drug  Administration,  or  FDA, 
reviewer,  and  National  Cancer  Institute,  or  NCI,  research  scientist,  helped  guide  the  company's  initial 
research and commercialization efforts in targeted cancer drugs.  Our mission is to discover, develop and 
market innovative therapeutics that address unmet medical needs. 

Industry Background 

Overview 

Our research and development focuses on three therapeutic areas that affect the lives of many 
people—cancer, CNS and mood disorders, and sexual dysfunction.  All of these disorders can have a 
debilitating effect on the quality of life for patients who suffer from them.  Our strategy is to develop 
drugs that satisfy unmet needs in the market and help patients regain quality of life by providing 
innovative therapeutics. 

According to the American Cancer Society's Cancer Facts & Figures 2008, cancer is the second 
leading  cause  of  death  among  Americans  and  is  responsible  for  one  of  every four  deaths  in  the  United 
States.  In 2008, more than 565,650 Americans are expected to die of cancer and approximately 1,437,180 
new  cases  are  expected  to  be  diagnosed.    These  estimates  do  not  include  non-invasive  cancer  (except 
urinary  bladder)  or  more  than  1 million  cases  of  basal  and  squamous  cell  skin  cancers  expected  to  be 
diagnosed in 2008. 

Worldwide, it is predicted that the number of new cancer cases diagnosed will rise to 16 million 
annually in 2020 from 11 million in 2002, with cancer-related deaths reaching 10 million in 2020 versus 
6.7 million in 2002.6 Cancer drug sales in 2005 were estimated to be $42 billion worldwide. Global sales 
of  cancer  drugs  are  predicted  to  grow  to  $60  billion  by  2010,  driven  mainly  by  commercialization  of 
molecular targeted therapies.7  

According  to  the  World  Health  Organization  (WHO),  154  million  cases  of  depression  are 
reported  worldwide  annually.  Antidepressant  drugs  are  the  largest  segment  of  global  CNS  therapeutics 
sales,  forecasted  at  $18  billion  for  2008.8   There  are  45  million  estimated  prevalent  cases  of  major 
depressive  disorder  (MDD)  in  the  US,  with  prevalence  rates  ranging  from  7%  to  15%.9   In  2006,  US 
revenues for antidepressants accounted for 77% of global total sales. Among the various drug classes of 
antidepressants, the selective serotonin re-uptake inhibitors/ serotonin-norepinephrine reuptake inhibitors

or  SSRI/SNRI  drugs  generated  approximately  59%  of  MDD-specific  revenues  while  non-SSRI/SNRIs 
accounted  for  41%. 10  Market  opportunities  include  new  depression  drugs  that  reduce  the  time  to 
therapeutic  onset,  have  new  mechanisms  of  action  for  better  efficacy  and  significantly  reduced  adverse 
reactions,  and  address  the  needs  of  an  aging  elderly  population  with  concomitant  neurodegenerative 
illnesses. 

There  are  150  million  estimated  men  with  erectile  dysfunction  or  ED  worldwide.  In  the  year 
2025,  it  is  estimated  that  322  million  men  worldwide  will  suffer  from  some  degree  of  sexual 
dysfunction.11  Current worldwide sales for all ED drugs are about $3 billion.12  ED is estimated to affect 
up to 30 million men in the United States13, with 52% of men between the ages of 40 and 70 reporting 
difficulty  with  erectile  function.14   About  30%  of  patients  are  refractory  to  PDE-5  inhibitors  such  as 
Viagra® and Cialis®, providing significant market opportunity for new class of ED drugs. 

Current Cancer Treatments 

The life-threatening nature of cancer, and the various ways of trying to cure cancer to save lives, 
has led to treatment(s) with surgery, radiation therapy, and chemotherapy. Surgery is widely used to treat, 
and in many cases cure cancer; however, there may be related or significant complications and surgery 
may be ineffective if metastasis has occurred.  Radiation therapy, or radiotherapy, can be highly effective.  
Ionizing radiation deposits energy that injures or destroys cells in the area being treated by damaging their 
genetic material, making it impossible for these cells to continue to grow.  Although radiation damages 
both cancer cells and normal cells, the normal cells are generally able to repair themselves and function 
properly.  In certain cancer tumor types, radiotherapy cure rates are as high as for surgery and can be used 
when  surgery  would  be unable  to  remove  the  tumor completely or  is  deemed  inappropriate.    Cytotoxic 
cancer  drugs  destroy  cancer  cells  by  interfering  with  various  stages  of  the  cell  division  process.  
Chemotherapy  is  used  as  a  primary  treatment  for  leukemia,  other  blood  cancers,  and  inoperable  or 
metastatic  solid  cancer  tumors.    However,  many  current  cytotoxic  chemotherapy  drugs  have  limited 
efficacy and debilitating adverse side effects and may result in the development of multi-drug resistance. 

Unmet Needs in Cancer Therapies 

Despite  significant  advances  in  cancer  research  and  treatments,  high  unmet  needs  remain 

including:  

•  Long-term  management  of  cancers:  Surgery, chemotherapy or radiation therapy may not 
result  in  long-term  remission,  though  surgery  and  radiation  therapies  are  considered  cure 
methods.  Therefore, there is a need for more effective drugs and adjuvant therapies to treat 
relapsed and refractory cancers. 

•  Multi-drug  resistance:  Multi-drug  resistance  is  a  major  obstacle  in  successful  clinical 

outcomes for patients with chemotherapeutics. 

•  Debilitating  toxicity  by  chemotherapy:  Chemotherapy  as  a  mainstay  of  cancer  treatment 

induces severe adverse reactions and toxicities, affecting quality of life or life itself.

Current Renal Cell Carcinoma Treatments 

There  are  two  main  treatment  approaches  for  RCC.  First,  for  earlier  stages  I-III,  radical  or 
nephron-sparing  surgery  is  used  to  remove  part,  or  all,  of  the  kidney  for  tumor  resection.  Second,  the 
typical  treatment  approach  for  advanced,  stage  IV  RCC  involves  immunotherapy  using  the  cytokines 
interleukin-2  (IL-2)  and  interferon-alpha  (IFN-alpha).  Cytokines  have  limited  efficacy  and  significant 
toxicities.  Only  4%  to  6%  of  all  RCC  tumors  respond  completely  to  immunotherapy.    From  2006  and 
onward,  immunotherapy  has  been  giving  way  to  the  advent  of  new  RCC  treatment  using  molecular 
targeted therapeutics such as Nexavar and Sutent. 

Unmet Needs in RCC Treatment 

The lead indication for ArchexinTM is renal cell carcinoma (RCC). RCC incidence is increasing 
by  3%  annually.15 Among  the  most  difficult  cancers  to  treat,  RCC  has  an  estimated  208,000  incident 
cases  worldwide  and  40,000  U.S.  cases.  More  than  102,000  die  from  RCC  annually  according  to  the 
Kidney  Cancer  Association  (2005).  Only  20%  of  metastatic  RCC  tumors  respond  to  standard  therapy, 
leaving  80%  of  advanced  RCC  patients  with  no  effective  treatment.  Further,  up  to  30  to  50%  of  RCC 
stage  I-III  patients  relapse  following  treatment  or  surgical  resection.  Once  metastatic  disease  develops, 
five-year survival is low and ranges from 0% to 20%.16  There remain high unmet needs in RCC such as 
the need for adjuvant therapy following surgery, drug resistance, and less toxic and more effective drugs. 

Archexin™:  First-in-class anti-cancer Akt Inhibitor 

ArchexinTM  is  a  first-in-class,  potent  inhibitor  of  the  Akt-1  protein  kinase  in  cancer  cells. 
ArchexinTM is in Phase II trials for treatment of renal cell carcinoma (RCC) and has US FDA orphan drug 
designations  for  five  cancers  (RCC,  glioblastoma,  and  cancers  of  the  ovary,  stomach  and  pancreas). 
Multiple indications for other solid tumors can also be pursued. ArchexinTM is differentiated by its ability 
to  inhibit  both  activated  and  inactivated  forms  of  Akt,  and  to  potentially  reverse  the  drug  resistance 
observed with the protein kinase inhibitors, whereas other targeted drugs may only inhibit inactivated Akt 
and be vulnerable to development of drug resistance. 

Role  of  Akt  in  Cancer.  Akt  activation  plays  a  key  role  in  cancer  cell  proliferation,  survival, 
angiogenesis and drug resistance. Akt is over-activated in many human cancers (e.g., breast, colorectal, 
gastric,  pancreatic,  prostate,  and  melanoma  cancers).  A  method  to  control  the  Akt  activity  involves 
inhibition of signaling molecules upstream of Akt in cancer cells (e.g., EGFR or VEGFR inhibitors). In 
this case, only the activity of native Akt is indirectly affected. However, signal transmission for cancer 
progression  and  resistance  occurs  when  Akt  is  activated,  thus  inhibition  of  the  activated  Akt  becomes 
more important. ArchexinTM inhibits both activated and native Akt. 

How  ArchexinTM  Inhibits  the  Akt.  ArchexinTM  is  an  antisense  oligonucleotide  (ASO) 
compound  that  is  complementary  to  Akt  mRNA,  and  highly  selective  for  inhibiting  mRNA  expression 
and production of Akt protein. 

Clinical  Development.    The  Phase  II  clinical  study  of  ArchexinTM  is  a  multicenter  trial  in 
patients with relapsed or refractory RCC.  In this trial, ArchexinTM is administered by continuous infusion 
for up to 6 cycles of therapy. ArchexinTM has demonstrated excellent tolerability and minimal side effects

in the Phase I clinical trial. The dose-limiting toxicity of ArchexinTM was grade 3 (G3) fatigue at the dose 
of 315 mg/m2/day. No significant hematological abnormalities were observed. 

We have been granted a U.S. patent for our Akt inhibitor compounds, including Archexin™. Our 

composition of matter patent covers broad claims for the nucleotide sequences of the anti-sense 
compounds that target and inhibit the expression of Akt in human tissues or cells, and the method of using 
the compounds to induce cytotoxicity in cancer cells. 

Current CNS Treatments 

The U.S. National Institute of Mental Health (NIMH) estimates that 26 percent of adults, or more 
than  55  million  Americans,  suffer  from  a  diagnosable  mental  disorder  in  a  given  year.  The  depression 
market  is  one  of  the  more  mature  and  established  markets  in  CNS  therapeutics.  Current  treatments  for 
depression focus on serotonin-based drugs (e.g., selective serotonin reuptake inhibitors, SSRIs) as a first-
line treatment. Many depression patients are refractory to the various classes of antidepressants and suffer 
from severe side effects. 

Unmet Needs in Depression 

High unmet needs for treating Major Depressive Disorder (MDD) include17: 

•  Faster onset of action. Current anti-depressants take four to six weeks to relieve depression 
symptoms. The delay in onset of anti-depressant activity is associated with the most common 
antidepressant  drug  classes  including:  selective  serotonin  reuptake  inhibitors  (SSRIs), 
inhibitors 
serotonin-norepinephrine  reuptake 
(MAOIs), and tricyclic antidepressants (TCAs). 

inhibitors  (SNRIs),  monoamine  oxidase 

•  Fewer  side  effects.  The  most  widely  used  anti-depressants,  SSRIs,  are  linked  with  side 
effects of insomnia, weight gain and sexual dysfunction. The safety of SSRIs has also been 
called into question over concerns about inducing suicidal ideations. Use of benzodiazepines 
is linked with side effects of cognitive deficit and motor impairment. 

• 

Improved  compliance.  High  rate  of  serious  side  effects  among  patients  taking  anti-
depressant drugs leads many to stop taking the prescribed medicines, resulting in high non-
compliance rates of 40% to 65%. 

•  Need  for  greater  efficacy.    Remission  is  one  key  objective  of  depression  treatment.    The 
proportion of patients achieving remission after antidepressant treatment ranges from 35% to 
55% depending on the severity of depression.18  New drugs with much higher efficacy as well 
as wider coverage of the depression patients are needed. 

•  Reduced MDD relapse.  High relapse rate of about 35% and lingering symptoms are serious 

problems in antidepressant treatment. 

17 Depression, June 2007; Stakeholder Insight: Major Depressive Disorder (MDD), March 2006 (Datamonitor). 
18 Remission rates tend to vary based on factors such as: treatment algorithm and drugs prescribed, patient geographic population 
or country, prescribing doctor (primary care, psychiatrist), and time at which remission rates are measured (3, 6, 8, or 10 weeks 
of treatment). Depression, June 2007; MDD, March 2006 (Datamonitor).

Serdaxin™: Antidepressant Drug 

Serdaxin™ is being developed to treat depression and mood disorders, and has proven and well-
established safety in humans. SerdaxinTM is a dual enhancer of serotonin and dopamine levels in the brain. 
It has a non-SSRI mechanism, and may effectively treat negative mood state and loss of positive mood 
state,  and  mixture  of  both  mood  states  as  well.    The  SSRI  class  of  antidepressants  is  suggested  to  be 
effective in treating the negative mood state, but not effective for the mood disorder resulting from loss of 
positive mood state. The loss of positive mood state may respond well to dopamine-based drugs. Studies 
to date indicate that SerdaxinTM has no motor impairment and cognition deficit of benzodiazepines, and 
no  insomnia,  weight  gain,  nausea  and  sexual  dysfunction  –  potentially  resulting  in  greater  medication 
compliance.    Of the disadvantages linked to SSRIs,  SNRIs, and benzodiazepines, SerdaxinTM addresses 
most  of  the  highest  unmet  needs  by  providing  potentially  faster  onset  of  action,  better  and  broader 
efficacy and fewer side effects. 

Current Sexual Dysfunction Treatment 

The launch of Viagra® in 1998 as the first orally available phosphodiesterase (PDE)-5 inhibitor 
established a new standard of care for ED. Viagra® pioneered the ED market, and generated blockbuster 
sales.  Cialis®  and  Levitra®  were  subsequently  launched  in  2003  as  second-generation  PDE-5  inhibitor 
drugs. 

The  PDE-5  inhibitors  are  the  standard  of  care  in  ED  therapeutics.  Viagra®  has  brand  and 
prescriber loyalty, and long-standing established clinical data. Cialis® has a longer-lasting effect and is 
available  in  two  formulations,  a  long  acting  and  daily  dose.  Levitra®  has  greater  selectivity  to  act  on 
erectile  tissue.19 The  majority  of  ED  drugs  in  the  R&D  pipeline  work  by  a  ‘me-too’  PDE-5  inhibitor 
mechanism  of  action,  and  are  unlikely  to  establish  a  new  standard  of  care  for  the  future.20 Dopamine 
agonists  are  in  clinical  trials  for  ED,  but  those  drugs  tend  to  have  side  effects  of  nausea  and  vomiting. 
Generics will further impact competitive dynamics starting 2012 with Viagra® patent expiry followed by 
Cialis® and Levitra® in 2016 and 2018, respectively.21 

Unmet Needs in Sexual Dysfunction 

Viagra®, Cialis®, and Levitra® are about 45% to 70% effective with potential side effects such 
as  headaches,  GI  stomach  upset,  and  cardiovascular  issues.    PDE-5  inhibitors  are  designed  for  erectile 
function only, working by peripheral action on the blood vessels and erectile tissue. Certain segments of 
the ED patient population that respond less to PDE-5 inhibitors include diabetics, obese or post-surgical 
prostatectomy or coronary risk patients.22 PDE-5 inhibitors have significant drawbacks of cardiovascular 
risks  and  other  side  effects  (e.g.,  priapism,  severe  hypotension,  myocardial  infarction,  ventricular 
arrhythmias,  sudden  death  and  increased  intraocular  pressure).  Beyond  the  PDE-5  inhibitors,  there  is 
currently no single class of ED drugs to dominate the market.22 

Zoraxel™: Erectile Dysfunction (ED) Drug 

ZoraxelTM  is  a  CNS-based  sexual  dysfunction  drug  that  has  extensive  and  excellent  safety  in 
humans. ZoraxelTM is a dual serotonin and dopamine enhancer in the brain, where these neurotransmitters

play  a  key  role  in  three  phases  (sexual  motivation-arousal,  erection  and  release)  of  sexual  activity. 
ZoraxelTM may be the first ED drug to affect all three phases of the sexual activity. In pre-clinical studies 
and  animal  models,  ZoraxelTM  significantly  improved  sexual  performance  and  suggested  positive 
behavioral effects on sexual motivation and arousal. 

ZoraxelTM  Phase  II  trials  for  treatment  of  erectile  dysfunction  are  in  progress.  The  PDE-5 
inhibitors are the standard of care in ED therapeutics and are designed for erectile function only, working 
by peripheral action on the blood vessels and erectile tissue. In contrast, ZoraxelTM, which acts in the CNS 
affecting all three phases of sexual activity, including sexual arousal and release, may be superior to PDE-
5 inhibitors, and offer clinical benefits over dopamine agonists.  ZoraxelTM appears to be well-tolerated 
with excellent safety. 

Market Opportunity 

There  are  several  favorable  environmental  factors  for  commercializing  new  cancer  and  CNS 

drugs that may be first in class or market leaders, including: 

•  Favorable  Environment  for  Formulary  Access  and  Reimbursement.    Cancer  drugs  with 
proven efficacy or survival benefit, and cost-effective clinical outcomes would be expected to 
gain rapid market uptake, formulary listing and payer reimbursement. In addition, drugs that 
have orphan designations are generally reimbursed by insurance companies given that there 
are few, if any, alternatives.  Because mental disorders affect more than 55 million estimated 
Americans,  the  burden  of  illness  is  significant  for  insurance  companies  as  well  as  for 
employers.    Given  the  significant  cost  of  treating  behavioral  health  problems,  there  is  a 
favorable  environment  for  formulary  access  and  reimbursement  for  effective  products  that 
treat multiple disorders. 

•  Focus  on  Specialty  Markets.    The  marketing  of  new  drugs  to  specialty  physicians  can  be 
accomplished  with  a  specialty  sales  force  that  requires  fewer  personnel  and  lower  related 
costs  than  a  typical  sales  force  that  markets  to  primary  care  physicians  and  general 
practitioners.  

•  Expedited  Regulatory  or  Commercialization  Pathways.    Drugs  for  life-threatening  diseases 
such  as  cancer  are  often  treated  by  the  U.S.  Food  and  Drug  Administration  (FDA)  as 
candidates for fast track, priority and accelerated reviews.  Expedited regulatory review may 
lead to clinical studies that require fewer patients, or expedited clinical trials. Our lead CNS 
product,  Serdaxin™,  is  also  expected  to  have  expedited  or  shortened  clinical  development 
timelines  because  its  active  pharmaceutical  ingredient,  or  API,  has  extensive  and  well 
established safety in humans. 

Our Strategy 

Our strategy has several key components: 

•  Develop innovative therapeutics with the potential to be first-in-class or market leaders. 

•  Adopt orphan drug approach to reduce time to market. 

•  Strengthen our development efforts and pipeline through strategic alliances and partnerships. 

8 

 
 
 
 
 
 
 
 
 
 
 
 
 
•  Maximize advanced nanotechnology for developing innovative nano-medicines. 

Further, we plan to expand our R&D pipeline and introduce more new drugs into clinical trials 
over  the  next  five  years.    By  identifying  and  characterizing  the  genes  and  proteins  that  control  the 
signaling  pathways  and  gene  expression  of  cancer  cells,  we  seek  to  develop  unique  and  differentiated 
drugs to treat a broad range of diseases.  In addition, we will use our technology platforms to screen and 
identify compounds that could be promising lead product candidates to advance into research and clinical 
testing. 

Target Signal Transduction Molecules with Multiple Drug Candidates 

We plan to expand our drug candidate pipeline and introduce several new signal inhibitor drugs 
into clinical trials over the next five years.  By identifying and characterizing the genes and proteins that 
control the signaling pathways and gene expression of cancer cells, we seek to develop DNA/RNA-based 
and small-molecule drugs to treat a broad range of diseases caused by abnormal expression or functions 
of those genes and proteins.  In addition to developing our own signal transduction inhibitors, we will use 
our technology platforms to screen and identify compounds developed by other companies, either on their 
own  or  in  collaboration  with  us,  which  could  be  effective  signal  transduction  inhibitors  for  anti-cancer 
applications. 

Establish Partnerships with Large Pharmaceutical Companies 

We  seek  to  establish  partnerships  with  large  pharmaceutical  companies  in  order  to  reduce  drug 
development costs, expand the disease treatment indications, and leverage greater commercial and market 
opportunities.    We  plan  to  market  products  for  which  we  obtain  regulatory  approval  either  directly  or 
through  co-promotion  arrangements  or  other  licensing,  distribution,  or  alliance  arrangements  with  large 
pharmaceutical  companies.  To  date,  we  have  not  entered  into  such  agreements  with  any  large 
pharmaceutical companies. 

Clinically Develop Drug Candidates as Orphan Drugs to Reduce Time-to-Market 

Under  the  Orphan  Drug  Act,  the  FDA  may  expedite  approval  of  new  drugs  that  treat  diseases 
affecting less than 200,000 patients each year.  This category of diseases is called an "orphan indication".  
Incentives  in  the  Orphan  Drug  Act  include  a  faster  time-to-market  of  the  drug  (with  FDA  approval 
possible after Phase II trials instead of Phase III trials) and seven years of drug marketing exclusivity for 
the  sponsor.    In  addition,  the  FDA  sometimes  provides  orphan  research  grants  to  aid  in  the  costs  of 
developing an orphan drug.  Once the drug candidate has received orphan drug approval, the sponsor may 
conduct larger, more extensive clinical trials seeking approval for other, more widespread diseases. 

We plan to develop drug candidates initially for orphan category cancers in order to reduce the 
time-to-market.  This would enable us to either license these drugs for further development in multiple 
indications by major pharmaceutical companies or conduct the registration trials ourselves. 

In-License Unique Technology 

We continually review opportunities to in-license and advance compounds in oncology and other 
strategic therapeutic areas that have value creating potential and will strengthen our R&D pipeline.  For 
example,  in  February 2005,  we  licensed  the  intellectual  property  of  Revaax  Pharmaceuticals  LLC 
("Revaax")  to  develop  new  drugs  for  treatment  of  CNS  and  mood  disorders,  and  as  a  result  of  this 
licensing agreement, have advanced Serdaxin™ and Zoraxel™ into clinical trials planned for 2008.

Capitalize on Our Management Team's Expertise for Drug Development and Product 
Commercialization 

Commercializing  drugs  requires  regulatory,  clinical  development,  and  marketing  skill  sets  that 
our management team possesses.  Our regulatory knowledge comes from team members who have either 
been regulatory reviewers at the FDA or regulatory consultants who have prepared and filed regulatory 
documents  in  the  U.S.  and  worldwide.    Our  management  team  also  possesses  clinical  development 
experience  in  oncology  and  several  other  therapeutic  areas,  that  facilitates  strategic  approaches  to,  and 
competitive  advantages  in,  the  design,  risk  assessment,  and  implementation  of  drug  development 
programs. We also have prior experience in pharmaceutical alliances, product launches and marketing. 

Our Pipeline Drug Candidates 

We have three clinical stage or clinic ready drugs in development, and several more pre-clinical 

drugs, including the following: 

Clinical Stage Pipeline 

(1)  Archexin™: First-in-class anti-cancer Akt inhibitor 

(2)  Serdaxin™: Antidepressant Drug 

(3)  Zoraxel™: Erectile Dysfunction (ED) drug 

Pre-clinical Pipeline 

(4)  RX-0201-Nano: Nanoliposomal anti-cancer Akt-1 inhibitor 

(5)  RX-0047-Nano: Nanoliposomal anti-cancer HIF-1 alpha inhibitor 

(6)  Nano-polymer Anticancer Drugs: HPMA-docetaxel and HPMA-gemcitabine 

We have discussed our clinical stage pipeline in detail above. 

Pre-clinical Pipeline 

Our pre-clinical pipeline includes: 

(1) RX-0201-Nano: Nanoliposomal anti-cancer Akt-1 inhibitor 

RX-0201,  the  active  ingredient  of  ArchexinTM,  is  a  first-in-class,  potent  inhibitor  of  the  Akt-1 
protein kinase. RX-0201-Nano is a nanoliposomal product of RX-0201 with high incorporation efficiency 
and  good  stability.  Nanoliposomal  delivery  of  RX-0201  may  provide  significant  clinical  benefits 
including  targeted  higher  cellular  uptake,  extended  circulation  time,  reduced  drug-related  toxicity,  and 
improved efficacy. Phase I trials are planned for 2009. 

(2) RX-0047-Nano: Nanoliposomal anti-cancer HIF-1α inhibitor 

RX-0047-Nano  is  a  nanoliposomal  cancer  drug  candidate  that  selectively  inhibits  expression  of 
the HIF-1α transcription factor. HIF-1α is a key signaling molecule in angiogenesis, cancer cell survival 
and  invasion,  and  radiation  resistance.    RX-0047  is  a  first-in-class  anticancer  candidate  that  directly 

10 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
inhibits expression of mRNA and protein of HIF-1α. HIF-1α is over-expressed in a broad range of human 
cancers, and associated with increased cancer mortality and resistance. In pre-clinical studies, RX-0047 
significantly downregulated expression of HIF-1α mRNA and protein. At nanomolar concentrations, RX-
0047 inhibited proliferation of cancer cells from human solid tumors and growth of implanted tumors in 
xenograft  animal  models,  and  reversed  resistance  in  radiation-resistant  cancer  cells.  RX-0047  inhibited 
growth  of  solid  tumors  in  lung  as  well  as  prostate  cancer  xenograft  models,  and  significantly  blocked 
metastasis in a lung metastatic model. RX-0047-Nano is expected to provide significant clinical benefits 
including  targeted  higher  cellular  uptake,  extended  circulation  time,  reduced  drug-related  toxicity,  and 
improved efficacy. Phase I trials are planned for 2009. 

(3) Nano-polymer Anticancer Drugs- HPMA-docetaxel and HPMA-gemcitabine 

A  major  problem  with  many  cancer  drugs  is  their  lack  of  tumor  specificity  and  dose-limiting 
toxicity.  Nano-polymer  conjugated  drugs  may  deliver  drugs  more  precisely  to  tumor  tissues  with  less 
toxic effects. Rexahn’s HPMA-docetaxel and HPMA-gemcitabine are expected to achieve the anticancer 
effects of docetaxel and gemcitabine, respectively, at much lower dose levels with significantly fewer side 
effects. Phase I trials may be initiated in 2009. 

Competition 

We are developing new drugs to address unmet medical needs in oncology, CNS disorders, and 
sexual  dysfunction  markets.    Our  drug  candidates  will  be  competing  with  products  and  therapies  that 
either currently exist or are expected to be developed.  Competition among these products will be based, 
among other things, on product efficacy, safety, reliability, price, launch timing and execution, and patent 
position.    Our  competitive  position  will  also  depend  upon  our  ability  to  attract  and  retain  qualified 
personnel,  to  obtain  patent  protection  or  otherwise  develop  proprietary  products  or  processes,  and  to 
secure sufficient capital resources for the often substantial period between technological conception and 
commercial sales. 

There are a number of pharmaceutical and biotechnology companies that are conducting research 
and  development  on  technologies  and  products  for  treatment  of  cancers,  CNS  diseases  and  sexual 
dysfunction.  Our competitors may succeed in developing products based on novel technologies that are 
more  effective  than  ours,  which  could  render  our  technology  and  products  noncompetitive  prior  to 
recovery by us of expenses incurred with respect to those products. 

Our  competitors  may  include  major  pharmaceutical,  specialized  biotechnology  firms,  and 
academic  and other research institutions.  Many of our competitors have substantially greater financial, 
technical  and  human  resources  than  we  do.    In  addition,  many  of  our  competitors  have  significantly 
greater  experience  than  we  do  in  undertaking  pre-clinical  testing  and  human  clinical  trials  of  new 
pharmaceutical products and obtaining FDA and other regulatory approvals of products for use in health 
care. 

As  we  expand  our  drug  development  programs  to  include  diseases  other  than  cancer,  CNS  and 
sexual  dysfunction,  we  will  also  face  competition  from  pharmaceutical  and  biotechnology  companies 
conducting  research  and  development  on  products  for  treatment  of  those  other  diseases,  increasing  our 
competition.  For many of the same reasons described above, we cannot assure you that we will compete 
successfully.

Competition for Archexin™ in Treating RCC 

Prior  to  2006  there  were  few,  if  any,  FDA-approved  drugs  for  treatment  of  RCC.  There  are 
currently  no  approved  RCC  adjuvant  therapies.  RCC  treatments  include  surgery  or  nephrectomy,  and 
cytokines,  immunotherapy,  and  cytotoxic  drugs.  Newer  drugs  for  RCC  include  multi-targeted  kinase 
inhibitors  (TKIs)  and  angiogenesis  inhibitors,  such  as:  Nexavar  (Bayer/Onyx),  Sutent  (Pfizer),  Torisel 
(Wyeth), and Avastin (Roche/Genentech).23  These targeted drugs are gaining market uptake as front line 
and  second  line  therapies;  however,  they  have  shown  only  limited  extended  survival  benefit  and  may 
have side effects such as skin rash, diarrhea, and hypertension. Cytotoxic drugs usually target, in a non-
specific way, all rapidly dividing cells including normal and healthy or non-cancerous cells such as those 
found in the blood, hair, and the lining of the gastrointestinal tract. Chemotherapy or cytotoxic drugs can 
damage  these  healthy  cells  leading  to  serious  and  debilitating  side  effects  such  as  nausea,  anemia, 
neutropenia,  hair  loss,  fatigue,  thrombocytopenia,  neuropathic  pain,  nerve  pain,  infection  and  even 
treatment-related  cancers.    Rexahn  is  developing  ArchexinTM  to  establish  a  new  standard  of  care  in 
treating  RCC  and  many  other  solid  tumors.  ArchexinTM  has  demonstrated  potential  for  greater  efficacy 
and safety, with minimal drug toxicity and side effects, and can be an important addition to current cancer 
treatments. 

Competition for Serdaxin™ in Treating Depression 

The market for branded antidepressant drugs is facing fierce generic competition and saturation 
of product reformulations. SSRI/SNRI drugs are the standard of care for treatment of depression. Leading 
brands include Effexor (Wyeth) and Lexapro (Forest/Lundbeck) with 2008 sales forecasts of $1.75 billion 
and  $1.85  billion,  respectively,  for  the  7  major  markets  (US,  Japan,  and  the  5  EU  major  country 
markets).24 As generic antidepressants continue entering the market, the patent protected brands and new 
market  entrants  will  need  to  be  highly  differentiated  from  established  generic  drugs.    Of  the  pipeline 
antidepressant  drugs  in  clinical  development,  SerdaxinTM  could  face  competition  from  the  anticipated 
launch(es)  for  agomelatine  starting  in  2009  (EU)  and  2010  (US).  Novartis/Servier  is  commercializing 
agomelatine  as  an  orally  available  once-daily  treatment.  It  is  a  melatonergic  antidepressant  that  has  a 
response rate in clinical trials similar to SSRIs.  Another antidepression drug in clinical trials is Sanofi-
Aventis’ Saredutant. Saredutant is a NK2 receptor antagonist and would be anticipated to launch in the US 
and EU in 2010.23 The most common side effects of SSRI antidepressant drug class include weight gain, 
dry mouth, insomnia, sexual dysfunction, diarrhea, nausea, and sleepiness. Despite its shortcomings, the 
SSRI class of drugs is the  most widely used to treat depression.   However, we believe that  Serdaxin™ 
may be a market leader and first in class antidepressant.  SerdaxinTM has extensive and well-established 
safety  in  humans,  and  may  possess  greater  efficacy  and  better  tolerability  compared  with  existing 
antidepressants. 

Competition for Zoraxel™ in Treating ED 

The PDE-5 inhibitors are the standard of care in ED therapeutics.  The majority of ED drugs in 
the R&D pipeline work by a ‘me-too’ PDE-5 inhibitor mechanism of action, and are unlikely to establish 
a new standard of care.25 Dopamine agonists are in clinical trials for ED, but those drugs tend to have side 
effects of nausea and vomiting.

Beyond  the  PDE-5  inhibitors,  there  is  currently  no  single  class  of  ED  drugs  to  dominate  the 
pipeline.  There are niche and larger market opportunities for ZoraxelTM.  ZoraxelTM works in the CNS by 
potentially  affecting  all  three  phases  of  sexual  activity,  including  sexual  arousal  and  release.  ZoraxelTM 
may be superior to PDE-5 inhibitors, offer clinical benefits over dopamine agonists, and provide a first in 
class ED drug that is well-tolerated with excellent safety. 

Government Regulation 

Regulation by governmental authorities in the United States and in other countries constitutes a 
significant  consideration  in  our  product  development,  manufacturing  and  marketing  strategies.    We 
expect  that  all  of  our  drug  candidates  will  require  regulatory  approval  by  appropriate  governmental 
agencies  prior  to  commercialization  and  will  be  subjected  to  rigorous  pre-clinical,  clinical,  and  post-
approval testing, as well as to other approval processes by the FDA and by similar health authorities in 
foreign  countries.    U.S. federal  regulations  control  the  ongoing  safety,  manufacture,  storage,  labeling, 
record keeping, and marketing of all biopharmaceutical products intended for therapeutic purposes.  We 
believe that we are in compliance in all material respects with currently applicable rules and regulations. 

Obtaining governmental approvals and maintaining ongoing compliance with federal regulations 
is  expected  to  require  the  expenditure  of  significant  financial  and  human  resources  not  currently  at  our 
disposal.  We plan to fulfill our short-term needs through consulting agreements and joint ventures with 
academic  or  corporate  partners  while  building  our  own  internal  infrastructure  for  long-term  corporate 
growth. 

The  process  by  which  biopharmaceutical  compounds  for  therapeutic  use  are  approved  for 
commercialization in the United States is lengthy.  Many other countries have instituted equally difficult 
approval  processes.    In  the  United  States,  regulations  published  by  the  FDA  require  that  the  person  or 
entity sponsoring and/or conducting a clinical study for the purpose of investigating a potential biological 
drug  product's  safety  and  effectiveness  submit  an  IND  application  to  the  FDA.    These  investigative 
studies are required for any drug product for which the product manufacturer intends to pursue licensing 
for  marketing  the  product  in  interstate  commerce.    If  the  FDA  does  not  object  to  the  IND  application, 
clinical testing of the compound may begin in humans after a 30-day review period.  Clinical evaluations 
typically are performed in three phases. 

In Phase I, the drug is administered to a small number of healthy human subjects or patients to 
confirm  its  safety  and  to  develop  detailed  profiles  of  its  pharmacological  and  pharmacokinetic  actions 
(i.e., absorption, metabolism, excretion, duration of therapeutic concentration and effects, if any). 

In Phase II, the drug is administered to groups of patients (up to a total of 500) to determine its 
preliminary efficacy against the targeted disease and the requisite dose and dose intervals.   In a typical 
development  program,  additional  animal  toxicology  studies  precede  this  phase.    Some  Phase I  clinical 
studies may also proceed in parallel with some Phase II studies. 

In  Phase  III,  the  drug  is  administered  to  a  larger  group  of  patients  (usually  1,000  to  3,000  or 
more)  by  physicians  (study  site  investigators)  in  a  network  of  participating  clinics  and  hospitals.    The 
extensive clinical testing is intended to confirm Phase II results and to document the nature and incidence 
of adverse reactions.  Studies also are performed in patients with concomitant diseases and medications.  
While  larger  patient  populations  are  evaluated  in  Phase  III  at  multiple  study  sites,  many  clinical  trial 
programs or registration studies could be conducted concurrently for the sake of time and efficiency. 

After  completing  the  IND  clinical  studies,  the  product  developer  submits  the  safety  and 
effectiveness data generated by the studies to the FDA in the form of a New Drug Application (NDA) to 

13 

 
 
 
 
 
 
 
 
 
market the product.  It is the legal responsibility of the FDA to review the proposed product labeling, the 
pre-clinical  (animal  and  laboratory)  data,  the  clinical  data,  as  well  as  the  facilities  utilized  and  the 
methodologies employed in the manufacture of the product which have been submitted to the agency to 
determine whether the product is safe and effective for its intended use. 

Even  after  initial  FDA  approval  has  been  obtained,  further  studies  may  be  required  to  provide 
additional data on safety or to gain approval for expanded labeling or treatment indications.   Also, the 
FDA  may  require  post-marketing  testing  and  surveillance  programs  to  monitor  the  drug's  effects.    Side 
effects resulting from the use of drug products may prevent or limit the further marketing of the products. 

For  marketing  outside  the  United  States,  we  will  be  subject  to  foreign  regulatory  requirements 
governing  human  clinical  trials  and  marketing  approval  for  drugs.    The  requirements  relating  to  the 
conduct  of  clinical  trials,  product  licensing,  pricing  and  reimbursement  vary  widely  from  country  to 
country. 

Certain drugs are eligible in the United States for designation by the FDA as "orphan" drugs if 
their  use  is  intended  to  treat  a  disease  that  affects  less  than  200,000 persons  in  the  U.S. or  the  disease 
affects more than 200,000 persons in the United States but there is no reasonable expectation that the cost 
of developing and marketing a drug will be recovered from the  U.S. sales of such drug.  In order for a 
sponsor to obtain orphan designation for a drug product, an application must be submitted for approval to 
the  FDA's  Office  of  Orphan  Products  Development.    The  approval  of  an  application  for  orphan 
designation  is  based  upon  the  information  submitted  by  the  sponsor.    A  drug  that  has  obtained  orphan 
designation is said to have "orphan status".  The approval of an orphan designation request does not alter 
the standard regulatory requirements and process for obtaining marketing approval.  Safety and efficacy 
of a compound must be established through adequate and well-controlled studies. 

Orphan  drugs  may  obtain  FDA  approval  after  successful  Phase  II  trials,  rather  than  after 
completion  of  Phase  III  trials,  resulting  in  faster  time-to-market  for  those  drugs.    If  a  sponsor  obtains 
orphan drug designation for a particular compound and is the first to obtain FDA regulatory approval of 
that compound, then that sponsor is granted marketing exclusivity for a period of seven years. 

Sales and Marketing 

Rexahn  plans  to  commercialize  unique  and  differentiated  drugs  that  are  first-in-class  or  market 
leaders,  and  establish  new  standards  of  care.  We  plan  to  develop  cancer  drugs  for  orphan  indications 
initially,  and  then  expand  into  more  highly  prevalent  cancers.  Currently,  ArchexinTM  has  Orphan  drug 
designation for five cancer indications. For drugs that require larger pivotal trials and/or large sales force, 
Rexahn  seeks  alliances  and  corporate  partnerships  with  larger  pharmaceutical  firms.  We  also  seek 
acquisition or in-licensing candidates to strengthen our product pipeline. 

While  Rexahn  may  build  an  in-house  sales  force  for  detailing  specialty  physician  markets,  the 
company  would  seek  pharmaceutical  or  commercialization  partners  to  market  drug(s)  to  larger  primary 
care physician audiences. There are inherent risks and advantages to establishing in-house sales force and 
commercial functions. The company would consider investment return metrics such as time to breakeven, 
internal rate of return, return on capital, etc. 

Rexahn  also  could  seek  to  expand  from  its  clinical-stage  capabilities  into  a  fully  integrated 
biopharmaceutical  company  by  using  the  following  business  models,  or  combination  thereof:    Fully-
integrated  pharma  company  (FIPCO)  with  its  own  sales  force;  Specialty  sales  force  focused  on  niche 
markets,  deployed  in  combination  with  contract  sales  force  and/or  co-promotion  efforts  with 
pharmaceutical partners; or Sales force with specific geographic rights or indications carved out. Strategic 

14 

 
 
 
 
 
 
 
 
 
plans  for  pricing,  branding,  customer  segmentation  and  targeting,  product  positioning,  reimbursement 
strategies, channel strategies, sales force sizing; and logistics and supply chain planning, would be driven, 
in part, by business considerations as set forth above, capital requirements, and commercial opportunity 
and forecasts. 

Research and Development  

Our research technologies are focused on our proprietary multi-target aimed ligands platform and 
nano-based  drug  delivery.  For  a  discussion  of  collaboration  arrangements  pursuant  to  which  we  obtain 
research  and  development  services  from  universities,  research  institutions  and  other  organizations,  see 
"Collaboration and License Agreements" in this Item. 

For  the  year  ending  December  31,  2007,  we  spent  $1,527,294  on  research  and  development 
activities,  which  included  payroll  of  $488,200,  studies  of  $252,709,  consulting  of  $251,637,  and  stock 
compensation  of  $534,748.    For  the  year  ending  December  31,  2006,  we  spent  $3,325,423  on  research 
and  development  activities,  which  included  payroll  of  $684,689,  studies  of  $2,053,303,  consulting  of 
$172,307, and stock compensation of $414,844. 

Multi-Target Ligands Platform 

Rexahn has developed a unique multi-target aimed ligands (MuTAL) platform. Because cancer is 
a complex disease caused by multiple factors as well as genetic modifications, cancer treatment involves a 
combination  of  drugs  with  different  mechanisms  of  action,  which  compound  degree  and  extent  of 
toxicities.    Our  approach  is  to  control  multiple  targets  important  for  cancer  proliferation  with  a  single 
agent.  In  doing  so,  Rexahn  utilizes  a  proprietary,  genomics-based  integrated  computational  modeling 
system to discover potentially important biological protein targets that control multiple genes or signaling 
events involved in cancer. 

Nanomedicine Delivery System 

We are developing unique nanomedicine delivery systems that may increase the availability of a 
drug at the disease site, minimize adverse reactions, and/or provide longer duration of action of a drug in 
the  body.  Rexahn  has  been  awarded  grants  from  Maryland  Industrial  Partnerships  (MIPS).  We  are 
currently 
technologies,  and 
collaborating with the Center for Nanomedicine of the University of Maryland to develop nano-medicines.

Manufacturing 

We  do  not  currently  have  the  resources  required  for  commercial  manufacturing  of  our  drug 
candidates.  We currently outsource the manufacturing of drug substances and drug products for our drug 
candidates.    We  have  no  current  plans  to  build  internal  manufacturing  capacity  for  any  product.  
Manufacturing  will  be  accomplished

Intellectual Property 

Proprietary  protection  for  our  drug  candidates,  processes  and  know-how  is  important  to  our 
business.  We plan to aggressively prosecute and defend our patents and proprietary technology.  Rexahn 
has several U.S. and international patents issued for broad IP coverage of our drug candidates in cancer, 
CNS, behavioral and mood disorders, neuroprotection and sexual dysfunction.  Additional U.S., Europe, 
and  foreign  patents  are  pending.    Our  policy  is  to  file  patent  applications  to  protect  technology, 

15 

 
 
 
 
 
 
 
 
 
 
 
 
 
inventions, and improvements that are considered important to the development of our business.  We also 
rely  upon  trade  secrets,  know-how,  continuing  technological  innovation  and  licensing  opportunities  to 
develop and maintain our competitive position. 

In  March 2005,  we  licensed-in  CNS-related  intellectual  property from  Revaax  Pharmaceuticals, 
LLC.  The intellectual property rights acquired cover use of certain compounds for anxiety, depression, 
aggression, cognition, Attention Deficit Hyperactivity Disorder, neuroprotection and sexual dysfunction.

under this agreement is jointly owned by us and UMB. 

Revaax Pharmaceuticals LLC ("Revaax").  On February 10, 2005, 
we licensed on an exclusive basis, with the right to sublicense, all of 
the intellectual property of Revaax, which includes five patents and 14 
patent  applications,  with  respect  to  certain  chemical  structures  that 
have demonstrated in pre-clinical research the potential to treat certain 
behavioral  disorders,  such  as  anxiety,  depression  and  cognitive

RISK FACTORS 

You should carefully consider the risks described below together with the other information included in 
this Annual Report on Form 10-KSB.  Our business, financial condition or results of operations could be 
adversely affected by any of these risks.  If any of these risks occur, the value of our common stock could 
decline. 

We  currently  have  no  product  revenues  and  will  need  to  raise  additional  capital  to  operate  our 
business. 

To date, we have generated no product revenues.  Until we receive approval from the FDA and 
other regulatory authorities for our drug candidates, we cannot sell our drugs and will not have product 
revenues.    Therefore,  for  the  foreseeable  future,  we  will  have  to  fund  all  of  our  operations  and  capital 
expenditures from the net proceeds of equity or debt offerings we may make, cash on hand, licensing fees 
and  grants.    Over  the  next  12  months  we  expect  to  spend  approximately  $1 million  on  clinical 
development  for  Phase  II  clinical  trials  of  Archexin™.    Based  on  our  current  plans  and  our  capital 
resources,  we  believe  that  our  cash  and  cash  equivalents  will  be  sufficient  to  enable  us  to  meet  our 
planned operating needs for at least the next 12 months, including the clinical trials of Archexin™.  We 
plan to initiate Phase II clinical trials of Serdaxin™ and Zoraxel™ beginning in 2008 at an additional cost 
of up to approximately $1 million. 

However,  changes  may  occur  that  would  consume  our  existing  capital  at  a  faster  rate  than 
projected, including but not limited to, the progress of our research and development efforts, the cost and 
timing of regulatory approvals and the costs of protecting our intellectual property rights.  We may seek 
additional financing to implement and fund other drug candidate development, clinical trial and research 
and development efforts, including Phase I clinical trials for other new drug candidates, as well as other 
research and development projects, which together with the current operating plan for the next year, could 
aggregate up to $6 million through the first quarter of 2009. 

We will need additional financing to continue to develop our drug candidates, which may not be 
available  on  favorable  terms,  if  at  all.    If  we  are  unable  to  secure  additional  financing  in  the  future  on 
acceptable terms, or at all, we may be unable to complete our planned pre-clinical and clinical trials or 
obtain approval of our drug candidates from the FDA and other regulatory authorities.  In addition, we 
may be forced to reduce or discontinue product development or product licensing, reduce or forego sales 
and  marketing  efforts  and  forego  attractive  business  opportunities  in  order  to  improve  our  liquidity  to 
enable us to continue operations.  Any additional sources of financing will likely involve the sale of our 
equity securities or securities convertible into our equity securities, which may have a dilutive effect on 
our stockholders. 

We are not currently profitable and may never become profitable. 

We  have  generated  no  revenues  to  date  from  product  sales.    Our  accumulated  deficit  as  of 
December 31,  2007  and  2006  was  $24,994,331  and  $20,690,326,  respectively.    For  the  years  ended 
December 31, 2007 and 2006, we had net losses of $4,304,005 and $6,486,003, respectively, primarily as 
a result of expenses incurred through a combination of research and development activities related to the 
various technologies under our control and expenses supporting those activities.  Even if we succeed in 
developing and commercializing one or more of our drug candidates, we expect to incur substantial losses 
for  the  foreseeable  future  and  may  never  become  profitable.    We  also  expect  to  continue  to  incur 
significant operating and capital expenditures and anticipate that our expenses will increase substantially 
in the foreseeable future, based on the following considerations: 

18 

 
 
 
 
 
 
 
 
• 

• 

• 

• 

continued  pre-clinical  development  and  clinical  trials  for  our  current  and  new  drug 
candidates; 

efforts to seek regulatory approvals for our drug candidates; 

implementing additional internal systems and infrastructure; 

licensing in additional technologies to develop; and 

•  hiring additional personnel. 

We also expect to continue to experience negative cash flow for the foreseeable future as we fund 
our operating losses and capital expenditures.   As a result, we will need to generate significant revenues 
in order to achieve profitability. 

We have a limited operating history. 

We  are  a  development-stage  company  with  a  limited  number  of  drug  candidates.    To  date,  we 
have not demonstrated an ability to perform the functions necessary for the successful commercialization 
of any of our drug candidates.  The successful commercialization of our drug candidates will require us to 
perform a variety of functions, including, but not limited to: 

• 

conducting pre-clinical and clinical trials; 

•  participating in regulatory approval processes; 

• 

• 

formulating and manufacturing products; and 

conducting sales and marketing activities. 

To  date,  our  operations  have  been  limited  to  organizing  and  staffing  our  company,  acquiring, 
developing  and  securing  our  proprietary  technology,  drug  candidate  research  and  development  and 
undertaking,  through  third  parties,  pre-clinical  trials  and  clinical  trials  of  our  principal  drug  candidates.  
These operations provide a limited basis for assessment of our ability to commercialize drug candidates. 

We  may  not  obtain  the  necessary  U.S. or  worldwide  regulatory  approvals  to  commercialize  our  drug 
candidates. 

We will need FDA approval to commercialize our drug candidates in the U.S. and approvals from 
the FDA-equivalent regulatory authorities in foreign jurisdictions to commercialize our drug candidates in 
those jurisdictions.  In order to obtain FDA approval of our drug candidates, we must submit to the FDA a 
New Drug Application ("NDA") demonstrating that the drug candidate is safe for humans and effective 
for its intended use.  This demonstration requires significant research and animal tests, which are referred 
to as pre-clinical studies, as well as human tests, which are referred to as clinical trials.  Satisfaction of the 
FDA's  regulatory  requirements  typically  takes  many  years,  and  depends  upon  the  type,  complexity  and 
novelty  of  the  drug  candidate  and  requires  substantial  resources  for  research,  development  and  testing.  
We  cannot  predict  whether  our  research  and  clinical  approaches  will  result  in  drugs  that  the  FDA 
considers safe for humans and effective for indicated uses.  Two of our drug candidates, Archexin™ and 
RX-0047, are ASO compounds.  To date, the FDA has not approved any NDAs for any ASO compounds.  
In addition, each of Archexin™, RX-0201-nano and RX-0047-nano is of a drug class (Akt inhibitor, in 

19 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
the case of Archexin™ and RX-0201-nano, and HIF inhibitor, in the case of RX-0047) that has not been 
approved by the FDA to date, nor have we submitted such NDA.  After the clinical trials are completed, 
the FDA has substantial discretion in the drug approval process and may require us to conduct additional 
pre-clinical and clinical testing or to perform post-marketing studies. 

In  foreign  jurisdictions,  we  must  receive  approval  from  the  appropriate  regulatory  authorities 
before we can commercialize our drugs.  Foreign regulatory approval processes generally include all of 
the risks associated with the FDA approval procedures described above.  We cannot assure you that we 
will  receive  the  approvals  necessary  to  commercialize  our  drug  candidates  for  sale  outside  the  United 
States. 

Our drug candidates are in early stages of clinical trials. 

Our drug candidates are in an early stage of development and require extensive clinical testing, 
which  are  very  expensive,  time-consuming  and  difficult  to  design.    In  2007,  Archexin™,  an  oncology 
drug candidate, entered Phase II clinical trials. We plan to initiate Phase II clinical trials of Serdaxin™ 
and Zoraxel™, neuroscience and sexual dysfunction drug candidates, beginning in 2008. 

Clinical trials are very expensive, time-consuming and difficult to design and implement. 

Human clinical trials are very expensive and difficult to design and implement, in part because 
they  are  subject  to  rigorous  regulatory  requirements.    The  clinical  trial  process  is  also  time  consuming.  
We estimate that clinical trials of our current drug candidates will take at least three years to complete.  
Furthermore, failure can occur at any stage of the trials, and we could encounter problems that cause us to 
abandon or repeat clinical trials.  The commencement and completion of clinical trials may be delayed by 
several factors, including, but not limited to: 

•  unforeseen safety issues; 

•  determination of dosing issues; 

• 

• 

• 

• 

• 

lack of effectiveness during clinical trials; 

reliance on third party suppliers for the supply of drug candidate samples; 

slower than expected rates of patient recruitment; 

inability to monitor patients adequately during or after treatment; 

inability or unwillingness of medical investigators and institutional review boards to follow 
our clinical protocols; and 

• 

lack of sufficient funding to finance the clinical trials. 

In  addition,  we  or  the  FDA  may  suspend  clinical  trials  at  any  time  if  it  appears  that  we  are 
exposing  participants  to  unacceptable  health  risks  or  if  the  FDA  finds  deficiencies  in  our  IND 
submissions or the conduct of these trials. 

20 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
If  the  results  of  our  clinical  trials  fail  to  support  our  drug  candidate  claims,  the  completion  of 
development  of  such  drug  candidate  may  be  significantly  delayed  or  we  may  be  forced  to  abandon 
development altogether, which will significantly impair our ability to generate product revenues. 

Even  if  our  clinical  trials  are  completed  as  planned,  we  cannot  be  certain  that  our  results  will 
support our drug candidate claims.  Success in pre-clinical testing and early clinical trials does not ensure 
that later clinical trials will be successful, and we cannot be sure that the results of later clinical trials will 
replicate the results of prior clinical trials and pre-clinical testing.  The clinical trial process may fail to 
demonstrate that our drug candidates are safe for humans and effective for indicated uses.  This failure 
would cause us to abandon a drug candidate and may delay development of other drug candidates.  Any 
delay  in,  or  termination  of,  our  clinical  trials  will  delay  the  filing  of  our  NDAs  with  the  FDA  and, 
ultimately,  delay  our  ability  to  commercialize  our  drug  candidates  and  generate  product  revenues.    In 
addition, our trial designs may involve a small patient population.  Because of the small sample size, the 
results of early clinical trials may not be indicative of future results. 

If physicians and patients do not accept and use our drugs, our ability to generate revenue from sales 
of our products will be materially impaired. 

Even if the FDA approves our drug candidates, physicians and patients may not accept and use 

them.  Future acceptance and use of our products will depend upon a number of factors including: 

• 

awareness of the drug's availability and benefits; 

•  perceptions by members of the health care community, including physicians, about the safety 

and effectiveness of our drugs; 

•  pharmacological benefit and cost-effectiveness of our product relative to competing products; 

• 

• 

availability of reimbursement for our products from government or other healthcare payers; 

effectiveness of marketing and distribution efforts by us and our licensees and distributors, if 
any; and 

• 

the price at which we sell our products. 

Because we expect sales of our current drug candidates, if approved, to generate substantially all 
of  our  product  revenues  for  the  foreseeable  future,  the  failure  of  any  of  these  drugs  to  find  market 
acceptance would harm our business and could require us to seek additional financing. 

Much of our drug development program depends upon third-party researchers, and the results of our 
clinical trials and such research activities are, to a limited extent, beyond our control. 

We  depend  upon  independent  investigators  and  collaborators,  such  as  universities  and  medical 
institutions, to conduct our pre-clinical and clinical trials and toxicology studies.  This business practice is 
typical for the pharmaceutical industry and companies like us.  For example, the Phase I clinical trials of 
Archexin™  were  conducted  at  the  Lombardi  Comprehensive  Cancer  Center  of  Georgetown  Medical 
Center  and  the  University  of  Alabama  at  Birmingham,  with  the  assistance  of  Amarex,  LLC,  a 
pharmaceutical clinical research service provider who is responsible for creating the reports that will be 
submitted to the FDA.  We also relied on TherImmune Research Corporation (now named Bridge Global 
Pharmaceutical Services, Inc.), a discovery and pre-clinical service provider, to summarize Archexin™ 's 

21 

 
 
 
 
 
 
 
 
 
 
 
 
 
pre-clinical data.  While we make every effort internally to oversee their work, these collaborators are not 
our employees and we cannot control the amount or timing of resources that they devote to our programs.  
These investigators may not assign priority to our programs or pursue them as diligently as we would if 
we were undertaking such programs ourselves.  If outside collaborators fail to devote sufficient time and 
resources to our drug-development programs, or if their performance is substandard, the approval of our 
FDA  applications,  if  any,  and  our  introduction  of  new  drugs,  if  any,  may  be  delayed.    The  risk  of 
completion or delay of these studies is not within our direct control and a program delay may occur due to 
circumstances outside our control.  A delay in any of these programs may not necessarily have a direct 
impact  on  our  daily  operations.    However,  to  the  extent  that  a  delay  results  in  additional  cost  to  us,  a 
higher  than  expected  expense  may  result.  These  collaborators  may  also  have  relationships  with  other 
commercial entities, some of whom may compete with us.  If our collaborators assist our competitors at 
our expense, our competitive position would be harmed. 

We rely exclusively on third parties to formulate and manufacture our drug candidates, which expose 
us to a number of risks that may delay development, regulatory approval and commercialization of our 
products or result in higher product costs. 

We have no experience in drug formulation or manufacturing.  Internally, we lack the resources 
and  expertise  to  formulate  or  manufacture  our  own  drug  candidates.    Therefore,  we  rely  on  third  party 
expertise  to  support  us  in  this  area.    For  example,  we  have  entered  into  contracts  with  third-party 
manufacturers  such  as  Raylo  Chemicals  Inc.,  Formatech,  Inc.,  Avecia  Biotechnology  Inc.  and  UPM 
Pharmaceuticals, Inc. to manufacture, supply, store and distribute supplies of our drug candidates for our 
clinical  trials.    If  any  of  our  drug  candidates  receive  FDA  approval,  we  will  rely  on  these  or  other 
third-party contractors to manufacture our drugs.  Our reliance on third-party manufacturers exposes us to 
the following potential risks: 

•  We may be unable to identify manufacturers on acceptable terms or at all because the number 
of potential manufacturers is limited and the FDA must approve any replacement contractor.  
This  approval  would  require  new  testing  and  compliance  inspections.    In  addition,  a  new 
manufacturer would have to be educated in, or develop substantially equivalent processes for, 
the production of our products after receipt of FDA approval, if any. 

•  Our third-party manufacturers might be unable to formulate and manufacture our drugs in the 

volume and of the quality required to meet our clinical needs and commercial needs. 

•  Our  contract  manufacturers  may  not  perform  as  agreed  or  may  not  remain  in  the  contract 
manufacturing  business  for  the  time  required  to  supply  our  clinical  trials  or  to  successfully 
produce, store and distribute our products. 

•  Drug manufacturers are subject to ongoing periodic unannounced inspection by the FDA, the 
Drug  Enforcement  Agency  ("DEA"),  and  corresponding  state  agencies  to  ensure  strict 
compliance  with  good  manufacturing  practice  and  other  government  regulations  and 
corresponding  foreign  standards.    We  do  not  have  control  over  third-party  manufacturers' 
compliance  with  these  regulations  and  standards,  but  we  may  be  ultimately  responsible  for 
any of their failures. 

• 

If  any  third-party  manufacturer  makes  improvements  in  the  manufacturing  process  for  our 
products,  we  may  not  own,  or  may  have  to  share,  the  intellectual  property  rights  to  the 
innovation. 

22 

 
 
 
 
 
 
 
 
 
Each  of  these  risks  could  delay  our  clinical  trials,  drug  approval  and  commercialization  and 

potentially result in higher costs and/or reduced revenues. 

We have no experience selling, marketing or distributing products and currently no internal capability 
to do so. 

We currently have no sales, marketing or distribution capabilities.  While we intend to have a role 
in  the  commercialization  of  our  products,  we  do  not  anticipate  having  the  resources  in  the  foreseeable 
future to globally develop sales and marketing capabilities for all of our proposed products.  Our future 
success depends, in part, on our ability to enter into and maintain collaborative relationships with other 
companies having sales, marketing and distribution capabilities, the collaborator's strategic interest in the 
products  under  development  and  such  collaborator's  ability  to  successfully  market  and  sell  any  such 
products.  To the extent that we decide not to, or are unable to, enter into collaborative arrangements with 
respect to the sales and marketing of our proposed products, significant capital expenditures, management 
resources and time will be required to establish and develop an in-house marketing and sales force with 
technical expertise.  We cannot assure you that we will be able to establish or maintain relationships with 
third  party  collaborators  or  develop  in-house  sales  and  distribution  capabilities.    To  the  extent  that  we 
depend  on  third  parties  for  marketing  and  distribution,  any  revenues  we  receive  will  depend  upon  the 
efforts of such third parties, as well as the terms of its agreements with such third parties, which cannot be 
predicted  at  this  early  stage  of  our  development.    We  cannot  assure  you  that  such  efforts  will  be 
successful.  In addition, we cannot assure you that we will be able to market and sell our products in the 
United States or overseas. 

Developments by competitors may render our products or technologies obsolete or non-competitive. 

We will compete against fully integrated pharmaceutical companies and smaller companies that 
are  collaborating  with  larger  pharmaceutical  companies,  such  as  Keryx  Biopharmaceuticals,  Genta 
Incorporated  and  Imclone  Systems  Incorporated,  as  well  as  academic  institutions,  government  agencies 
and other public and private research organizations. In addition, many of these competitors, either alone 
or together with their collaborative partners, operate larger research and development programs or have 
substantially greater financial resources than we do, as well as more experience in: 

•  developing drugs; 

•  undertaking pre-clinical testing and human clinical trials; 

•  obtaining FDA and other regulatory approvals of drugs; 

• 

• 

formulating and manufacturing drugs; and 

launching, marketing and selling drugs. 

Large  pharmaceutical  companies  such  as  Bristol-Myers  Squibb,  Eli-Lilly,  Novartis  and  Glaxo-
SmithKline  currently  sell  both  generic  and  proprietary  compounds  for  the  treatment  of  cancer.    In 
addition, companies pursuing different but related fields represent substantial competition.  Many of these 
organizations  have  substantially  greater  capital  resources,  larger  research  and  development  staffs  and 
facilities,  longer  drug  development  history  in  obtaining  regulatory  approvals  and  greater  manufacturing 
and  marketing  capabilities  than  we  do.    These  organizations  also  compete  with  us  to  attract  qualified 
personnel, parties for acquisitions, joint ventures or other collaborations. 

23 

 
 
 
 
 
 
 
 
 
 
 
 
If we fail to adequately protect or enforce our intellectual property rights or secure rights to patents of 
others, the value of our intellectual property rights would diminish and our business and competitive 
position would suffer. 

Our success, competitive position and future revenues will depend in part on our ability and the 
abilities of our licensors to obtain and maintain patent protection for our products, methods, processes and 
other  technologies,  to  preserve  our  trade  secrets,  to  prevent  third  parties  from  infringing  on  our 
proprietary rights and to operate without infringing the proprietary rights of third parties.  We have filed 
U.S. and  PCT  patent  applications  for  anti-Akt  compounds,  including  Archexin™  and  anti-HIF 
compounds,  including  RX-0047.    In  November 2006,  we  were  granted  a  U.S. patent  for  our  anti-Akt 
compounds,  including  Archexin™.    The  patent  covers  the  nucleotide  sequences  of  the  anti-sense 
compounds that target and inhibit the expression of Akt in human tissues or cells.  The patent also covers 
the  method  of  using  the  compounds  to  induce  cytotoxicity  in  cancer  cells.    We  have  also  filed  three 
U.S. provisional  patent  applications  for  new  anti-cancer  quinazoline  compounds,  new  anti-cancer 
nucleoside products and a drug target, cenexin, a polo-box binding protein.  In December 2004, we also 
filed two Korean patent applications for new anti-cancer piperazine compounds.  Through our licensing 
agreement with Revaax, we hold exclusive rights to five patents and 14 patent applications, with respect 
to certain chemical structures related to antibiotics, but without antibiotic efficacy.  However, we cannot 
predict: 

• 

the degree and range of protection any patents will afford us against competitors, including 
whether  third  parties  will  find  ways  to  invalidate  or  otherwise  circumvent  our  licensed 
patents; 

• 

if and when patents will issue; 

•  whether  or  not  others  will  obtain  patents  claiming  aspects  similar  to  those  covered  by  our 

licensed patents and patent applications; or 

•  whether we will need to initiate litigation or administrative proceedings which may be costly 

whether we win or lose. 

Our  success  also  depends  upon  the  skills,  knowledge  and  experience  of  our  scientific  and 
technical personnel, our consultants and advisors as well as our licensors and contractors.  To help protect 
our  proprietary  know-how  and  our  inventions  for  which  patents  may  be  unobtainable  or  difficult  to 
obtain,  we  rely  on  trade  secret  protection  and  confidentiality  agreements.    To  this  end,  we  require  all 
employees  to  enter  into  agreements  that  prohibit  the  disclosure  of  confidential  information  and,  where 
applicable, require disclosure and assignment to us of the ideas, developments, discoveries and inventions 
important to our business.  These agreements may not provide adequate protection for our trade secrets, 
know-how  or  other  proprietary  information  in  the  event  of  any  unauthorized  use  or  disclosure  or  the 
lawful  development  by  others  of  such  information.    If  any  of  our  trade  secrets,  know-how  or  other 
proprietary information is disclosed, the value of our trade secrets, know-how and other proprietary rights 
would be significantly impaired and our business and competitive position would suffer. 

If we infringe the rights of third parties we could be prevented from selling products and be forced to 
pay damages and defend against litigation. 

If our products, methods, processes and other technologies infringe the proprietary rights of other 

parties, we could incur substantial costs and may have to: 

24 

 
 
 
 
 
 
 
 
 
 
•  obtain licenses, which may not be available on commercially reasonable terms, if at all; 

• 

• 

redesign our products or processes to avoid infringement; 

stop using the subject matter claimed in the patents held by others, which could cause us to 
lose the use of one or more of our drug candidates; 

•  pay damages; or 

•  defend litigation or administrative proceedings which may be costly whether we win or lose, 

and which could result in a substantial diversion of our management resources. 

Although to date, we have not received any claims of infringement by any third parties, as our 
drug candidates  move into clinical trials and commercialization, our public profile and that of our drug 
candidates may be raised and generate such claims. 

Our license agreement with Revaax may be terminated in the event we commit a material breach, the 
result of which would significantly harm our business prospects. 

Our license agreement with Revaax is subject to termination by Revaax if we materially breach 
our obligations under the agreement, including breaches with respect to certain installment payments and 
royalty payments, if such  breaches are  not cured within a 60-day period.  The agreement also provides 
that it may be terminated if we become involved in a bankruptcy, insolvency or similar proceeding.  If 
this  license  agreement  is  terminated,  we  will  lose  all  of  our  rights  to  develop  and  commercialize  the 
licensed compounds, including Serdaxin™ and Zoraxel™, which would significantly harm our business 
and future prospects. 

If we are unable to successfully manage our growth, our business may be harmed. 

In addition to our own internally developed drug candidates, we proactively seek opportunities to 
license  in  and  advance  compounds  in  oncology  and  other  therapeutic  areas  that  are  strategic  and  have 
value  creating  potential  to  take  advantage  of  our  development  know-how.    We  are  actively  pursuing 
additional  drug  candidates  to  acquire  for  development.    Such  additional  drug  candidates  could 
significantly  increase  our  capital  requirements  and  place  further  strain  on  the  time  of  our  existing 
personnel,  which  may  delay  or  otherwise  adversely  affect  the  development  of  our  existing  drug 
candidates.  Alternatively, we may be required to hire more employees, further increasing the size of our 
organization  and  related  expenses.    If  we  are  unable  to  manage  our  growth  effectively,  we  may  not 
efficiently  use  our  resources,  which  may  delay  the  development  of  our  drug  candidates  and  negatively 
impact our business, results of operations and financial condition. 

We  may  not  be  able  to  attract  and  retain  qualified  personnel  necessary  for  the  development  and 
commercialization of our drug candidates.  Our success may be negatively impacted if key personnel 
leave. 

Attracting and retaining qualified personnel will be critical to our future success.  We compete for 
qualified  individuals  with  numerous  biopharmaceutical  companies,  universities  and  other  research 
institutions.    Competition  for  such  individuals  is  intense,  and  we  cannot  assure  you  that  we  will  be 
successful. 

25 

 
 
 
 
 
 
 
 
 
  
 
 
 
The  loss  of  the  technical  knowledge  and  management  and  industry  expertise  of  any  of our  key 
personnel,  especially  Dr. Chang  H.  Ahn,  our  Chairman  and  Chief  Executive  Officer  and  regulatory 
expert,  could  result  in  delays  in  product  development  and  diversion  of  management  resources,  which 
could adversely affect our operating results.  We do not have "key person" life insurance policies for any 
of our officers. 

We may incur substantial liabilities and may be required to limit commercialization of our products in 
response to product liability lawsuits. 

The testing and marketing of medical products entail an inherent risk of product liability.  If we 
cannot successfully defend ourselves against product liability claims, we may incur substantial liabilities 
or  be  required  to  limit  commercialization  of  our  products.    Our  inability  to  obtain  sufficient  product 
liability insurance at an acceptable cost to protect against potential product liability claims could prevent 
or  inhibit  the  commercialization  of  pharmaceutical  products  we  develop,  alone  or  with  collaborators.  
Although  we  currently  carry  clinical  trial  insurance  and  product  liability  insurance  we,  or  any 
collaborators, may not be able to maintain such insurance at a reasonable cost.  Even if our agreements 
with any future collaborators entitles us to indemnification against losses, such indemnification may not 
be available or adequate should any claim arise. 

An investment in shares  of our common stock is  very speculative and involves a very high degree of 
risk. 

To  date,  we  have  generated  no  revenues  from  product  sales  and  only  minimal  revenues  from  a 
research  agreement  with  a  minority  shareholder,  and  interest  on  bank  account  balances  and  short-term 
investments.    Our  accumulated  deficit  as  of  December 31,  2007  and  2006  was  $24,994,331  and 
$20,690,326,  respectively.    For  the  years  ended  December 31,  2007  and  2006,  we  had  net  losses  of 
$4,304,005  and  $6,486,003,  respectively,  primarily  as  a  result  of  expenses  incurred  through  a 
combination of research and development activities related to the various technologies under our control 
and expenses supporting those activities.  Until we receive approval from the FDA and other regulatory 
authorities for our drug candidates, we cannot sell our drugs and will not have product revenues. 

The market price of our common stock may fluctuate significantly. 

The market price of our common stock may fluctuate significantly in response to factors, some of 

which are beyond our control, such as: 

• 

the announcement of new products or product enhancements by us or our competitors; 

•  developments concerning intellectual property rights and regulatory approvals; 

•  variations in our and our competitors' results of operations; 

• 

changes in earnings estimates or recommendations by securities analysts; and 

•  developments in the biotechnology industry. 

Further, the stock market, in general, and the market for biotechnology companies, in particular, 
have experienced extreme price and volume fluctuations.  Continued market fluctuations could result in 
extreme  volatility  in  the  price  of  our  common  stock,  which  could  cause  a  decline  in  the  value  of  our 
common stock.  You should also be aware that price volatility might be worse if the trading volume of 

26 

 
 
 
 
 
 
 
 
 
 
 
 
 
our common stock is low.  We have not paid, and do not expect to pay, any cash dividends because we 
anticipate that any earnings generated from future operations will be used to finance our operations and as 
a result, you will not realize any income from an investment in our common stock until and unless you 
sell your shares at a profit. 

Some  or  all  of  the  "restricted"  shares  of  our  common  stock  issued  in  the  merger  of  CPRD  and 
Rexahn, Corp or held by other stockholders may be offered from time to time in the open market pursuant 
to  Rule 144,  and  these  sales  may  have  a  depressive  effect  on  the  market  for  our  common  stock.    In 
general, an affiliated person who has held restricted shares for a period of six months may, upon filing 
with  the  SEC  a  notification  on  Form 144,  sell  into  the  market  common  stock  in  an  amount  equal  to 
1 percent  of  the  outstanding  shares  (approximately  550,000  shares)  during  a  three-month  period.    Non-
affiliates may sell restricted securities after six months without any limits on volume. 

Trading of our common stock is limited. 

Trading  of  our  common  stock  is  currently  conducted  on  the  National  Association  of  Securities 
Dealers' Over-the-Counter Bulletin Board ("OTC-BB").  The liquidity of our securities has been limited, 
not only in terms of the number of securities that can be bought and sold at a given price, but also through 
delays in the timing of transactions and reduction in security analysts' and the media's coverage of us. 

These factors may result in lower prices for our common stock than might otherwise be obtained 
and  could  also  result  in  a  larger  spread  between  the  bid  and  asked  prices  for  our  common  stock.  
Currently, there are approximately 600 holders of record of our common stock. 

Because our common stock may be a "penny stock," it may be more difficult for you to sell shares of 
our common stock, and the market price of our common stock may be adversely affected. 

Our  common  stock  may  be  a  "penny  stock"  if,  among  other  things,  the  stock  price  is  below 
$5.00 per  share,  we  are  not  listed  on  a  national  securities  exchange  or  approved  for  quotation  on  the 
Nasdaq  Stock  Market,  or  we  have  not  met  certain  net  tangible  asset  or  average  revenue  requirements.  
Broker-dealers  who  sell  penny  stocks  must  provide  purchasers  of  these  stocks  with  a  standardized 
risk-disclosure document prepared by the SEC.  This document provides information about penny stocks 
and the nature and level of risks involved in investing in the penny-stock market.  A broker must also give 
a  purchaser,  orally  or  in  writing,  bid  and  offer  quotations  and  information  regarding  broker  and 
salesperson compensation, make a written determination that the penny stock is a suitable investment for 
the  purchaser,  and  obtain  the  purchaser's  written  agreement  to  the  purchase.    Broker-dealers  must  also 
provide customers that hold penny stock in their accounts with such broker-dealer a  monthly statement 
containing price and market information relating to the penny stock.  If a penny stock is sold in violation 
of the penny stock rules, purchasers may be able to cancel their purchase and get their money back.  If 
applicable,  the  penny  stock  rules  may  make  it  difficult  for  investors  to  sell  their  shares  of  our  stock.  
Because of the rules and restrictions applicable to a penny stock, there is less trading in penny stocks and 
the  market  price  of  our  common  stock  may  be  adversely  affected.    Also,  many  brokers  choose  not  to 
participate in penny stock transactions.  Accordingly, purchasers may not always be able to resell shares 
of our common stock publicly at times and prices that they feel are appropriate. 

Item 2.  Description of Property. 

We lease approximately 8,030 square feet of laboratory and office space at 9620 Medical Center 
Drive,  Rockville,  Maryland,  20850.    The  facility  is  equipped  with  the  requisite  laboratory  services 
required to conduct our business and we believe that our existing facilities are adequate to meet our needs 
for the foreseeable future.  Our lease expires on June 30, 2009.  We do not own any real property.

Item 6.  Management's Discussion and Analysis or Plan of Operation 

You  should  read  the  following  discussion  and  analysis  of  our  results  of  operations,  financial  condition 
and liquidity in conjunction with our financial statements and the related notes, which are included in this 
Annual Report on Form 10-KSB.  Some of the information contained in this discussion and analysis or set 
forth elsewhere in this Annual Report on Form 10-KSB, including information with respect to our plans 
and strategies for our business, statements regarding the industry outlook, our expectations regarding the 
future  performance  of  our  business,  and  the  other  non-historical  statements  contained  herein  are 
forward-looking statements.  See "Cautionary Statement Regarding Forward-Looking Statements".  You 
should also review the "Risk Factors" section under this Item 1 of this Annual Report for a discussion of 
important factors that could cause actual results to differ materially from the results described herein or 
implied by such forward-looking statements. 

Overview 

Our  company  resulted  from  the  merger  of  Corporate  Road  Show.Com  Inc.,  a  New  York 
corporation  incorporated  in  November 1999,  and  Rexahn,  Corp,  a  Maryland  corporation,  immediately 
after  giving  effect  to  our  reincorporation  as  a  Delaware  corporation  under  the  name  "Rexahn 
Pharmaceuticals,  Inc."    In  connection  with  that  transaction,  a  wholly  owned  subsidiary  of  ours  merged 
with  and  into  Rexahn,  Corp,  with  Rexahn,  Corp  remaining  as  the  surviving  corporation  and  a  wholly 
owned  subsidiary  of  ours.    In  exchange  for  their  shares  of  capital  stock  in  Rexahn,  Corp,  the  former 
stockholders of Rexahn, Corp received shares of common stock representing approximately 91.8% of the 
Company's outstanding equity after giving effect to the transaction.  Further, upon the effective time of 
the  Merger,  our  historic  business  was  abandoned  and  the  business  plan  of  Rexahn,  Corp  was  adopted.  
The transaction was therefore accounted for as a reverse acquisition with Rexahn, Corp as the accounting 
acquiring party and CPRD as the acquired party.  In September 2005, Rexahn, Corp was merged with and 
into the Company. 

Our  efforts  and  resources  have  been  focused  primarily  on  acquiring  and  developing  our 
pharmaceutical  technologies,  raising  capital  and  recruiting  personnel.    We  are  a  development  stage 
company  and  have  no  product  sales  to  date  and  we  will  not  receive  any  product  sales  until  we  receive 

30 

 
 
 
 
 
 
 
 
 
approval  from  the  FDA  or  equivalent  foreign  regulatory  bodies  to  begin  selling  our  pharmaceutical 
candidates.    Our  major  sources  of  working  capital have  been  proceeds  from  various  private  financings, 
primarily  private  sales  of  common  stock  and  debt  securities,  and  collaboration  agreements  with  our 
strategic investors. 

Critical Accounting Policies 

A  "critical  accounting  policy"  is  one  which  is  both  important  to  the  portrayal  of  our  financial 
condition  and  results  and  requires  our  management's  most  difficult,  subjective  or  complex  judgments, 
often as a result of the need to make estimates about the effect of matters that are inherently uncertain.  
Our accounting policies are in accordance with United States generally accepted accounting principles, or 
GAAP, and their basis of application is consistent with that of the previous year. 

Use of Estimates 

The preparation of financial statements in conformity with GAAP requires management to make 
estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of 
contingent  assets  and  liabilities  at  the  date  of  the  financial  statements  and  the  reported  amounts  of 
revenues  and  expenses  during  the  reporting  period.    These  estimates  are  based  on  management's  best 
knowledge of current events and actions the Company may undertake in the future.  Actual results may 
ultimately  differ  from  those  estimates.    These  estimates  are  reviewed  periodically  and  as  adjustments 
become necessary, they are reported in earnings in the period in which they become available. 

Stock-Based Compensation 

Effective  January  1,  2006,  the  Company’s  Plan  is  accounted  for  in  accordance  with  the 
recognition  and  measurement  provisions  of  Statement  of  Financial  Accounting  Standards  ("FAS")  No. 
123 (revised 2004), Share-Based Payment ("FAS 123(R)"), which replaces FAS No. 123, Accounting for 
Stock-Based  Compensation,  and  supersedes  Accounting  Principles  Board  Opinion  ("APB")  No.  25, 
Accounting  for  Stock  Issued  to  Employees,  and  related  interpretations.  FAS  123(R)  requires 
compensation costs related to share-based payment transactions, including employee stock options, to be 
recognized in the financial statements. In addition, the Company adheres to the guidance set forth within 
Securities  and  Exchange  Commission  ("SEC")  Staff  Accounting  Bulletin  No.  107  ("SAB  107"),  which 
provides the Staff's views regarding the interaction between SFAS No. 123(R) and certain SEC rules and 
regulations and provides interpretations with respect to the valuation of share-based payments for public 
companies.  See Note 7 to the Financial Statements in Item 7 of this Annual Report for further details. 

Recently Issued Accounting Standards 

The  Company  accounts  for  income  taxes  pursuant  to  Statement  of  Financial  Accounting 
Standards  ("SFAS")  No.  109,  "Accounting  for  Income  Taxes".    Deferred  tax  assets  and  liabilities  are 
recorded for differences between the financial statement and tax basis of the assets and liabilities that will 
result  in  taxable  or  deductible  amounts  in  the  future  based  on  enacted  tax  laws  and  rates.    Valuation 
allowances  are  established  when  necessary  to  reduce  deferred  tax  assets  to  the  amount  expected  to  be 
realized.    Income  tax  expense  is  recorded  for  the  amount  of  income  tax  payable  or  refundable  for  the 
period, increased or decreased by the change in deferred tax assets and liabilities during the period. 

On  January 1,  2007,  the  Company  adopted  Financial  Accounting  Standards  Board  (FASB) 
Interpretation  No. 48,  “Accounting  for  Uncertainty  in  Income  Taxes—an  interpretation  of  FASB 
Statement  No. 109”  (FIN  48). There  was  no  impact  on  the  Company’s  consolidated  financial  position, 
results  of  operations  or  cash  flows  at  December 31,  2007  and  for  the  year  then  ended  as  a  result  of 

31 

 
 
 
 
 
 
 
 
 
 
 
implementing FIN 48. At the adoption date of January 1, 2007 and at December 31, 2007, the Company 
did  not  have  any  unrecognized  tax  benefits.  The  Company’s  practice  is  to  recognize  interest  and/or 
penalties related to income tax matters in income tax expense. As of January 1, 2007 and December 31, 
2007, the Company had no accrued interest or penalties. The Company currently has no federal or state 
tax examinations in progress nor has it had any federal or state tax examinations since its inception. As a 
result  of  the  Company’s  net  operating  loss  carryforwards,  all  of  its  tax  years  are  subject  to  federal  and 
state tax examination. 

In  September  2006,  the  staff  of  the  SEC  issued  Staff  Accounting  Bulletin  ("SAB")  No.  108, 
which  provides  interpretive  guidance  on  how  the  effects  of  the  carryover  or  reversal  of  prior  year 
misstatements  should  be  considered  in  quantifying  a  current  year  misstatement.  SAB  108  became 
effective in fiscal year end December 31, 2007. Adoption of SAB 108 did not have a material impact on 
the Company's financial position, results of operations or cash flows. 

In December 2006, the FASB issued FASB Staff Position ("FSP") EITF 00-19-2 "Accounting for 
Registration  Payment  Arrangements"  ("FSP  EITF  00-19-2")  which  specifies  that  the  contingent 
obligation  to  make  future  payments  or  otherwise  transfer  consideration  under  a  registration  payment 
arrangement should be separately recognized and measured in accordance with SFAS No. 5, "Accounting 
for Contingencies." Adoption of FSP EITF 00-19-02 is required for fiscal years beginning after December 
15, 2006, and did not have a material impact on the Company's financial position, results of operations or 
cash flows. 

In  September  2006,  the  FASB  issued  SFAS  No. 157,  Fair  Value  Measurements,  which  defines 
fair value, establishes a framework for measuring fair value in generally accepted accounting principles, 
and  expands  disclosures  about  fair  value  measurements.  This  statement  does  not  require  any  new  fair 
value  measurements,  but  provides  guidance  on  how  to  measure  fair  value  by  providing  a  fair  value 
hierarchy  used  to  classify  the  source  of  the  information.  SFAS  No. 157  is  effective  for  fiscal  years 
beginning after November 15, 2007, and all interim periods within those fiscal years. In December 2007, 
the FASB released a proposed FASB Staff Position (FSP FAS 157-b - Effective Date of FASB Statement 
No. 157)  which,  if  adopted  as  proposed,  would  delay  the  effective  date  of  SFAS  No. 157  for  all 
nonfinancial assets and nonfinancial liabilities, except those that are recognized or disclosed at fair value 
in the financial statements on a recurring basis (at least annually). We do not believe that adoption of this 
statement would have a material impact on our financial statements. 

In February 2007, the FASB issued SFAS No. 159, “The Fair Value Option for Financial Assets 
and Financial Liabilities” (“SFAS No. 159”). SFAS No. 159 permits entities to choose to measure, on an 
item-by-item basis, specified financial instruments and certain other items at fair value.  Unrealized gains 
and losses on items for which the fair value option has been elected are required to be reported in earnings 
at each reporting date.  SFAS No. 159 is effective for fiscal years beginning after November 15, 2007, the 
provisions of which are required to be applied prospectively. The Company expects to adopt SFAS No. 
159 in the first quarter of Fiscal 2008 and is still evaluating the effect, if any, on its financial position or 
results of operations. 

In June 2007, the EITF Issue 07-03, “Accounting for Advance Payments for Goods or Services to 
Be Used in Future Research and Development” (EITF 07-03). EITF 07-03 addresses the diversity which 
exists with respect to the accounting for the non-refundable portion of a payment made by a research and 
development  entity  for  future  research  and  development  activities.  Under  EITF  07-03,  an  entity  would 
defer and capitalize non-refundable advance payments made for research and development activities until 
the  related  goods  are  delivered  or  the  related  services  are  performed.  EITF  07-03  is  effective  for  fiscal 
years  beginning  after  December 15,  2007  and  interim  periods  within  those  years.  The  Company  is 

32 

 
 
 
 
 
 
currently evaluating the potential impact from adopting EITF 07-03 on the financial position or results of 
operations. 

In  December  2007,  the  Financial  Accounting  Standards  Board  (“FASB”)  issued  Statement  of 
Financial  Accounting  Standards  (“SFAS”)  No. 141  (revised  2007),  Business  Combinations,  which 
replaces  SFAS  No  141.  The  statement  retains  the  purchase  method  of  accounting  for  acquisitions,  but 
requires  a  number  of  changes,  including  changes  in  the  way  assets  and  liabilities  are  recognized  in  the 
purchase  accounting.  It  also  changes  the  recognition  of  assets  acquired  and  liabilities  assumed  arising 
from contingencies, requires the capitalization of in-process research and development at fair value, and 
requires the expensing of acquisition-related costs as incurred. SFAS No. 141R is effective for 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.  The adoption of SFAS 141R is not currently expected 
to have a material effect of the Company's Financial position, results of operations, or cash flows. 

In December 2007, the FASB issued SFAS No. 160.  “Noncontrolling Interests in Consolidated 
Financial Statements-and Amendment of ARB No. 51.”  SFAS 160 establishes accounting and reporting 
standards  pertaining  to  ownership  interests  in  subsidiaries  held  by  parties  other  than  the  parent,  the 
amount of net income attributable to the parent and to the noncontrolling interest, changes in a parent’s 
ownership interest, and the valuation of any retained noncontrolling equity investment when a subsidiary 
is  deconsolidated.    This  statement  also  establishes  disclosure  requirements  that  clearly  identify  and 
distinguish between the interests of the parent and the interests of the noncontrolling owners.  SFAS 160 
is effective for fiscal years beginning on or after December 15, 2008.  The adoption of SFAS 160 is not 
currently expected to have a material effect on the Company’s financial position, results of operations, or 
cash flows. 

In  March  2008,  the  Financial  Accounting  Standards  Board  (FASB)  issued  FASB  Statement 
No. 161, Disclosures about Derivative Instruments and Hedging Activities. The new standard is intended 
to improve financial reporting about derivative instruments and hedging activities by requiring enhanced 
disclosures to enable investors to better understand their effects on an entity’s financial position, financial 
performance,  and  cash  flows.  It  is  effective  for  financial  statements  issued  for  fiscal  years  and  interim 
periods beginning after November 15, 2008, with early application encouraged. The company is currently 
evaluating the impact of adopting SFAS. No. 161 on its financial statements. 

Results of Operations 

Comparison of the Year Ended December 31, 2007 and the Year Ended December 31, 2006 

Total Revenues 

During 2003 we entered into a collaborative research agreement with Rexgene Biotech Co., Ltd.  
("Rexgene"), a minority shareholder.  Rexgene is engaged in the development of pharmaceutical products 
in  Asia  and  has  agreed  to  assist  us  with  the  research,  development  and  clinical  trials  necessary  for 
registration of our Archexin™ drug candidate in Asia.  This agreement provides Rexgene with exclusive 
rights  to  license,  sublicense,  make,  have  made,  use,  sell  and  import  Archexin™  in  Asia.    A  one-time 
contribution to the joint development and research of Archexin™ of $1,500,000 was paid to us in 2003 in 
accordance  with  the  agreement.    The  amount  of  revenue  from  this  contribution  is  being  recognized  as 
income over the term of this agreement which terminates at the later of 20 years or the term of the patent 
on the licensed product.  We use 20 years as the basis for revenue recognition and accordingly $75,000 
was  included  in  revenues  in  each  fiscal  year  beginning  with  2003  and  the  remaining  $1,125,000  is 
reflected as deferred revenue on the balance sheet as of December 31, 2007.  We adopted SAB No. 104, 

33 

 
 
 
 
 
 
 
 
 
"Revenue Recognition - Nonrefundable Upfront Fees" with respect to the accounting for this transaction.  
These fees are to be used in the cooperative funding of the costs of development of Archexin™. 

General and Administrative Expenses 

General  and  administrative  expenses  consist  primarily  of  salaries  and  related  expenses  for 
executive, finance and other administrative personnel, recruitment expenses, professional fees and other 
corporate expenses, including business development and general legal activities. 

General  and  administrative  expenses  decreased  $323,341,  or  10.6%,  from  $3,051,493  in  fiscal 
2006 to $2,728,152 in fiscal 2007.  The decrease was due primarily to a decrease in professional fees and 
expenses.  Lower general and administrative expenses during fiscal 2007 were also attributable to lower 
stock compensation expense. 

Research and Development Expenses 

Research and development expenses consist primarily of salaries and related personnel costs, fees 
paid to consultants and outside service providers for laboratory development and other expenses relating 
to the design, development, testing, and enhancement of our drug candidates.  We expense our research 
and development costs as they are incurred. 

Research and development expenses decreased $1,798,129, or 54.1%, from $3,325,423 in fiscal 
2006 to $1,527,294 in fiscal 2007.  The decrease was due primarily to the fact that we paid a $1.8 million 
fee for drug manufacturing in 2006.  We expect that research and development expenses will increase as 
our other drug candidates move into the clinical trials phases of development. 

Patent Fees 

Our patent fees decreased $104,561, or 35.9%, from $291,174 in fiscal 2006 to $186,613 in fiscal 
2007.  The decrease was primarily due to the fact that we filed fewer new patent applications in 2007 as 
compared to 2006. 

Depreciation and Amortization 

Depreciation expense decreased $59,440, or 47.7%, from $124,510 in fiscal 2006 to $65,070 in 
fiscal 2007.  The decrease was due primarily to fewer unamortized balances in 2007 when compared to 
2006. 

Interest Expense 

Our  interest  expense  decreased  $99,651,  or  100%,  from  $99,651  in  fiscal  2006  to  $0  in  fiscal 
2007.  The decrease was due primarily to conversion of $3,850,000 principal amount of the Company's 
convertible notes into common stock in May 2006. 

Interest Income 

In fiscal 2007, we recorded $128,124 of interest income from the investment of our cash and cash 
equivalents  and  other  short-term  investments,  compared  to  $331,248  recorded  in  fiscal  2006.    The 
decrease of $203,124, or 61.3%, was primarily due to lower cash and cash equivalent balances and lower 
interest rates during fiscal 2007. 

34 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Research and Development Projects 

Research  and  development  expenses  are  expensed  as  incurred.    Research  and  development 
expenses  consist  primarily  of  salaries  and  related  personnel  costs,  costs  to  acquire  pharmaceutical 
products  and  product  rights  for  development  and  amounts  paid  to  contract  research  organizations, 
hospitals  and  laboratories  for  the  provision  of  services  and  materials  for  drug  development  and  clinical 
trials.  Costs incurred in obtaining the license rights to technology in the research and development stage 
and  that  have  no  alternative  future  uses  are  expensed  as  incurred.    Our  research  and  development 
programs  are  related  to  our  three  clinical  stage  lead  drug  candidates,  Archexin™,  Serdaxin™  and 
Zoraxel™  and  pre-clinical  stage  nano  drug  candidates,  RX-0201-Nano,  RX-0047-Nano  and  Nano-
polymer Anticancer Drugs.  We have allocated direct and indirect costs to each program based on certain 
assumptions and our review of the status of each program, payroll-related expenses and other overhead 
costs based on estimated usage by each program.  Each of our lead drug candidates is in various stages of 
completion  as  described  below.    As  we  expand  our  clinical  studies,  we  will  enter  into  additional 
development agreements.  Significant additional expenditures will be required if we complete our clinical 
trials, start new trials, apply for regulatory approvals, continue development of our technologies, expand 
our operations and bring our products to market.  The eventual total cost of each clinical trial is dependent 
on a number of uncertainties such as trial design, the length of the trial, the number of clinical sites and 
the  number  of  patients.    The  process  of  obtaining  and  maintaining  regulatory  approvals  for  new 
therapeutic  products  is  lengthy,  expensive  and  uncertain.    Because  the  successful  development  of  our 
most  advanced  drug  candidates,  Archexin™,  Serdaxin™  and  Zoraxel™,  is  uncertain,  and  because  RX-
0201-Nano, RX-0047-Nano and Nano-polymer Anticancer Drugs are in early-stage development, we are 
unable to estimate the costs of completing our research and development programs, the timing of bringing 
such  programs  to  market  and,  therefore,  when  material  cash  inflows  could  commence  from  the  sale  of 
these  drug  candidates.    If  these  projects  are  not  completed  as  planned,  our  results  of  operations  and 
financial  condition  could  be  negatively  affected  and  if  we  are  unable  to  obtain  additional  financing  to 
fund these projects, we may not be able to continue as a going concern. 

In  October  2006,  we  announced  the  conclusion  of  the  Phase  I  clinical  trial  of  Archexin™,  our 

leading drug candidate.  The costs incurred for the clinical trial was approximately $1,500,000. 

The Phase I clinical trial of Archexin™, which took place at Georgetown University's Lombardi 
Cancer Center beginning in September 2004 and at the University of Alabama at Birmingham beginning 
in  August 2005,  was  primarily  to  determine  the  safety  and  tolerability  of  the  drug  in  patients  with 
advanced cancer.  As the main purpose of the clinical trial was to establish the safety of Archexin ™, the 
parameters that determined the completion of this project were a direct function of the safety profile of 
this compound in humans.  As this was the first time that Archexin™ had been administered to humans, 
the safety profile in humans was unknown and, therefore, the number of doses required to determine the 
dosage at which the FDA safety endpoints would be met was estimated. 

As the main purpose of the clinical trial was to establish the safety of Archexin™, the parameters 
that  determined  the  completion  of  this  project  were  a  direct  function  of  the  safety  profile  of  this 
compound in humans.  As this was the first time that Archexin™ had been administered to humans, the 
safety  profile  in  humans  was  unknown  and  therefore,  the  number  of  doses  required  to  determine  the 
dosage at which the FDA safety endpoints would be met was estimated. 

The  Phase  II  clinical  trial  of  Archexin™  began  in  the  third  quarter  of  2007  in  patients  with 
advanced renal cell carcinoma who have failed previous treatments.  The trial is the first of multiple trials 
planned for Archexin™.  We estimate that the Phase II trials will be completed in 2009 and will require 
approximately $5,000,000.   In  January 2005,  we  received  "orphan  drug  designation"  from  the  FDA  for 

35 

 
 
 
 
 
 
 
Archexin™  for  five  cancer  indications,  including  renal  cell  carcinoma,  ovarian  cancer,  glioblastoma, 
stomach  cancer,  and  pancreatic  cancer.    The  orphan  drug  program  is  intended  to  provide  patients  with 
faster  access  to  drug  therapies  for  diseases  and  conditions  that  affect  fewer  than  200,000  people.  
Companies  that  receive  orphan  drug  designation  are  provided  an  accelerated  review  process,  tax 
advantages, and seven years of market exclusivity in the United States.  In the future, we plan to apply 
Archexin™ to the treatment of other orphan indications and other cancers. 

Serdaxin™  

SerdaxinTM is being developed to treat depression and mood disorders, and has proven and well-
established safety in humans.  Through December 31, 2007, the costs incurred for development of these 
compounds to date have been approximately $400,000.  Serdaxin™ is scheduled to enter Phase II trials in 
the second half of 2008. We currently estimate that these studies will require $3,000,000. 

Zoraxel™ 

ZoraxelTM  is  a  CNS-based  sexual  dysfunction  drug  that  has  extensive  and  excellent  safety  in 
humans.  Through  December 31,  2007,  the  costs  incurred  for  development  of  these  compounds  to  date 
have  been  approximately  $500,000.  Zoraxel™  is  scheduled  to  enter  Phase  II  trials  in  the  first  half  of 
2008. We currently estimate that these studies will require approximately $4,000,000. 

Pre-clinical Pipeline 

RX-0201-Nano, RX-0047-Nano and Nano-polymer Anticancer Drugs are in a pre-clinical stage 
of  development  and  the  next  scheduled  program  for  each  compound  is  a  pre-clinical  toxicology  study 
required prior to submission of an Investigational New Drug ("IND") application to the FDA.  Through 
December 31,  2007,  the  costs  incurred  for  development  of  these  compounds  to  date  have  been 
approximately  $1,000,000.    The  estimated  cost  to  complete  pre-clinical  toxicology  and  Phase  I  clinical 
trials is estimated to be approximately $1,500,000 per each compound for a total of $4,500,000.  These 
compounds may be entered into these Phase I clinical trials in 2009. 

The conduct of the clinical trial and toxicology studies described above are being accomplished in 
conjunction with third-party clinical research organizations, or CROs, at external locations.  This business 
practice  is  typical  for  the  pharmaceutical  industry  and  companies  like  us.    As  a  result,  the  risk  of 
completion or delay of these studies is not within our direct control and a program delay may occur due to 
circumstances outside our control.  A delay in any of these programs may not necessarily have a direct 
impact  on  our  daily  operations.    However,  to  the  extent  that  a  delay  results  in  additional  cost  to  us,  a 
higher than expected expense may result. 

Liquidity and Capital Resources 

Cash used in operating activities was $3,394,839 in fiscal 2007 compared to $5,843,198 in fiscal 
2006.  Fiscal 2007 operating cash flows reflect our loss from continuing operations of $4,304,005, offset 
by  net  non-cash  charges  of  $1,111,716  and  a  net  decrease  in  cash  components  of  working  capital  of 
$202,550.    Non-cash  charges  consist  of  depreciation  and  amortization  of  $65,070,  stock  option 
compensation expense of $1,121,646 and amortization of deferred revenue of $75,000.  The decrease in 
working capital primarily consists of a $31,469 increase in accounts payable and accrued expenses and an 
increase of $234,019 to prepaid and other assets.  Fiscal 2006 operating cash flows reflect our loss from 
continuing operations of $6,486,003, offset by net non-cash charges of $1,083,466 and a net decrease in 
cash  components  of  working  capital  of  $440,661.    Non-cash  charges  consisted  of  depreciation  and 

36 

 
 
 
 
 
 
 
 
 
 
amortization of $124,510, stock option compensation expense of $1,033,956 and amortization of deferred 
revenue of $75,000.  The decrease in working capital primarily consists of a $12,249 decrease in accounts 
payable and accrued expenses and an increase of $428,412 to prepaid and other assets. 

No  cash  was  used  in  investing  activities  in  fiscal  2007.    Cash  used  in  investing  activities  of 

$52,952 in fiscal 2006 consisted of capital expenditures for the purchase of equipment. 

Cash  used  in  financing  activities  of  $6,720,350  in  fiscal  2007  consists  of  proceeds  from  the 
issuance of common stock for cash of $6,800,023 offset by share issuance costs of $139,674 and upon the 
exercise of stock options of $60,000.  Cash used in financing activities of $186,415 in fiscal 2006 consists 
of principal payments on long-term debt of $172,813 and the purchase of treasury stock in the amount of 
$28,410,  offset  by  proceeds  of  $14,808  from  the  issuance  of  common  stock  upon  the  exercise  of  stock 
options. 

For the years ended December 31, 2007 and 2006, we experienced net losses of $4,304,005 and 
$6,486,003, respectively.  Our accumulated deficit as of December 31, 2007 and 2006 was $24,994,331 
and $20,690,326, respectively. 

We  have  financed  our  operations  since  inception primarily  through  equity  and  convertible  debt 
financings  and  interest  income  from  investments  of  cash  and  cash  equivalents.    During  fiscal  2007,  we 
had a net increase in cash and cash equivalents of $3,325,511.  This increase primarily resulted from the 
cash  provided  by  financing  activities  of  $6,720,350,  offset  by  cash  used  in  operating  activities  of 
$3,394,839. 

On December, 24, 2007 we received approximately $6,800,000  in net proceeds upon closing of 
the  sales  of  our  securities.  Such  sales  consisted  of  the  following:  (1)  sale  to  KT&G  Corporation  of 
2,142,858 shares of our common stock and a warrant to purchase 428,572 shares of our common stock for 
total consideration of $3,000,000; (2) sale to Rexgene Biotech Co., Ltd. of 714,286 shares of our common 
stock  and  a  warrant  to  purchase  142,857  shares  of  our  common  stock  for  total  consideration  of 
$1,000,000; (3) sale to Jungwoo Family Co., Ltd. of 142,857 shares of our common stock and a warrant 
to  acquire  up  to  28,571  shares  of  our  common  stock  for  aggregate  cash  consideration  of  $200,000;  (4) 
sale to Kumho Investment Bank of 357,143 shares of our common stock and a warrant to acquire up to 
71,429  shares  of  our  common  stock  for  aggregate  cash  consideration  of  $500,000;  and  (5)  sale  to  26 
individual Korean investors of a total of 1,500,015 shares of our common stock and a warrant to acquire 
up to 300,003 shares of our common stock for aggregate cash consideration of $2,100,000. 

For  the  foreseeable  future,  we  will  have  to  fund  all  of  our  operations  and  capital  expenditures 
from the net proceeds of equity and debt offerings we may make, cash on hand, licensing fees and grants.  
Although we have plans to pursue additional financing, there can be no assurance that we will be able to 
secure financing when needed or obtain such financing on terms satisfactory to us, if at all, or that any 
additional funding we do obtain will be sufficient to meet our needs in the long term. 

Contractual Obligations 

In  April 2004,  we  entered  into  a  clinical  development  agreement  with  Georgetown  University 
with  an  effective  period  from  April 5,  2004  through  April 5,  2006.    The  total  estimated  cost  of  the 
program is $223,126, based on the fees, enrollment and completion of 20 patients.  The clinical trial has 
been completed, but Georgetown University has not yet billed the Company for the services.  We expect 
to make a payment under the agreement in 2008. 

37 

 
 
 
 
 
 
 
 
 
 
In  April 2004,  we  signed  a  5-year  lease  for  8,030  square  feet  of  office  space  in  Rockville, 
Maryland  commencing  July 2004.    The  lease  requires  annual  base  rents  of  $200,750  subject  to  annual 
increases of 3% of the preceding years adjusted base rent.  Under the leasing agreement, we also pay our 
allocable portion of real estate taxes and common area operating charges. 

Minimum future rental payments under this lease are as follows: 

For the years ended December 31 

2008 
2009 

$  222,655 
    112,973 
$  335,628 

On  January 6,  2006,  we  contracted  with  Amarex,  LLC  to  conduct  Phase  II  clinical  studies  for 
Archexin™.  In accordance with the agreement, the estimated contract duration is 24 months for a total 
cost of $596,244 plus pass through expenses.  The service costs are payable in 24 monthly payments of 
$18,633 plus an up front payment of $149,061 due upon signing.  We paid $540,346 towards the cost of 
the study as of December 31, 2007.  In 2007, we added additional services to the Phase II clinical studies.   
The costs of these services totals $106,220, of which $87,603 was paid in 2007. 

On  October  2,  2003,  we  contracted  with  Amarex  to  conduct  Phase  I  clinical  studies  for 
Archexin™  (then  RX-0201).    Of  the  $239,337  to  be  paid  under  this  contract,  $194,461  was  paid  as  of 
December 31, 2007.  The balance will be paid when the final report is accepted, which is expected to be 
in 2008.  Since 2003, additional services were added to the study .  These services were contracted for 
$193,331, of which $186,619 was paid in 2007.  The balance will be paid in 2008. 

On  April 3,  2006,  we  contracted  with  UPM  Pharmaceuticals,  Inc.  to  develop  several  release 
formulations  for  Serdaxin™  and  Zoraxel™.    In  accordance  with  the  agreement,  the  estimated  contract 
duration  was  seven  months  for  an  estimated  cost  of  $433,925,  of  which  $112,937  was  paid  as  of 
December 31,  2007.    The  service  costs  were  payable  based  upon  a  payment  schedule  related  to  certain 
milestones.    During  2007,  additional  services  were  added  to  the  project.    The  cost  of  the  additional 
services is $42,050, of which $27,450 was paid as of December 31, 2007. 

On February 1, 2007, we entered into research agreement with University of Maryland Baltimore 
Biotechnology Institute to identify new JNK inhibitors using their NMR technology.  The total amount to 
be paid under this contract is $17,000, of which $10,000 was paid in 2007.  The balance will be paid in 
2008. 

On May 18, 2007, we contracted with Lab Connect to provide sample management and central 
laboratory services for Phase II clinical studies for Archexin™ clinical trials.  The total contract amount is 
estimated to be $197,220, of which $54,444 was paid in 2007.  The balance will be paid as services are 
performed over the next 32 months. 

On June 13, 2007, we contracted with Formatech to test the stability of Archexin™ package.  The 
total amount to be paid for this contract was $17,000, of which $10,000 was paid in 2007, and the balance 
will be paid when the final report is submitted, which is expected to be in three years. 

Current and Future Financing Needs 

We  have  incurred  negative  cash  flow  from  operations  since  we  started  our  business.    We  have 
spent, and expect to continue to spend, substantial amounts in connection with implementing our business 

38 

 
 
 
 
 
 
 
 
 
 
 
 
strategy,  including  our  planned  product  development  efforts,  our  clinical  trials,  and  our  research  and 
development efforts.  Based on our current plans and our capital resources, we believe that our cash and 
cash equivalents will be sufficient to enable us to meet our minimum planned operating needs for at least 
the next 12 months, which would entail focusing our resources on Phase II clinical trials of Archexin™, 
Serdaxin™ and Zoraxel™.  Over the next 12 months we expect to spend a minimum of approximately $1 
million  on  clinical  development  for  Phase  II  clinical  trials  of  Archexin™  (including  our  commitments 
described  under  "Contractual  Commitments"  of  this  Item 6),  $3 million  on  general  corporate  expenses, 
and approximately $223,000 on facilities rent.  We plan to initiate Phase II clinical trials of Serdaxin™ 
and Zoraxel™ beginning in 2008 at an additional cost of up to approximately $1 million for the next 12 
months.    We  may  seek  additional  financing  to  implement  and  fund  other  drug  candidate  development, 
clinical trial and research and development efforts to the maximum extent of our operating plan, including 
in-vivo animal and pre-clinical studies, Phase II clinical trials for new product candidates, as well as other 
research  and  development  projects,  which  together  with  the  minimum  operating  plan  for  the  next 
12 months, could aggregate up to $6 million through the first quarter of 2009. 

However, the actual amount of funds we will need to operate is subject to many factors, some of 

which are beyond our control.  These factors include the following: 

• 

• 

• 

• 

the progress of our product development activities; 

the number and scope of our product development programs; 

the progress of our pre-clinical and clinical trial activities; 

the  progress  of  the  development  efforts  of  parties  with  whom  we  have  entered  into 
collaboration agreements; 

•  our  ability  to  maintain  current  collaboration  programs  and  to  establish  new  collaboration 

arrangements; 

• 

the costs involved in prosecuting and enforcing patent claims and other intellectual property 
rights; and 

• 

the costs and timing of regulatory approvals. 

Impact of Inflation 

To date inflationary factors have not had a significant effect on our operations. 

Off-Balance Sheet Arrangements 

We do not have any off-balance sheet arrangements.

Item 7.  Financial Statements 

Report of Independent Registered Public Accounting Firm 

Board of Directors and Stockholders of 
Rexahn Pharmaceuticals, Inc. 
Rockville, Maryland 

We  have  audited  the  accompanying  balance  sheets  of  Rexahn  Pharmaceuticals,  Inc.  (a 
development  stage  company)  as  of  December  31,  2007  and  2006  and  the  related  statements  of 
operations,  stockholders’  equity  (deficit)  and  cash  flows  for  the years  ended  December  31, 2007 
and  2006  and  the  cumulative  period  from  inception  (March  19,  2001)  to  December  31,  2007.  
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 audits to 
obtain  reasonable  assurance  about  whether  the  financial  statements  are  free  of  material 
misstatement.  The Company is not required to have, nor were we engaged to perform, an audit of 
its internal control over financial reporting.  Our audits included consideration of internal control 
over  financial  reporting  as  a  basis  for  designing  audit  procedures  that  are  appropriate  in  the 
circumstances,  but  not  for  the  purpose  of  expressing  an  opinion  on  the  effectiveness  of  the 
Company’s  internal  control  over  financial  reporting.    Accordingly,  we  express  no  such  opinion.  
An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in 
the  financial  statements,  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 
financial position of Rexahn Pharmaceuticals, Inc. at December 31, 2007 and 2006 and the results 
of  its  operations  and  its  cash  flows  for  the  years  then  ended  and  the  cumulative  period  from 
inception  (March  19,  2001)  to  December  31,  2007,  in  conformity  with  accounting  principles 
generally accepted in the United States of America.

(A Development Stage Company) 
Notes to Financial Statements 
Years Ended December 31, 2007 and 2006 

1.  Operations and Organization 

Operations and Organization 

Rexahn  Pharmaceuticals,  Inc.  (the  "Company"  or  "Rexahn  Pharmaceuticals"),  a  Delaware 
corporation,  is  a  development  stage  biopharmaceutical  company  dedicated  to  the  discovery, 
development  and  commercialization  of  innovative  treatments  for  cancer,  central  nervous  system 
(CNS) disorders, sexual dysfunction and other medical needs.  

Reverse Merger Acquisition 

Pursuant to an Agreement and Plan of Merger by and among Rexahn, Corp ("Rexahn"), Corporate 
Road  Show.Com  Inc.  ("CRS"),  a  New  York  corporation  and  predecessor  corporation  of  the 
Company,  CRS  Merger  Sub,  Inc.,  a  Delaware  corporation  and  wholly  owned  subsidiary  of  CRS 
("Merger Sub"), CRS Delaware, Inc., a Delaware corporation and wholly owned subsidiary of CRS 
("CRS  Delaware"),  immediately  after  giving  effect  to  a  1-for-100  reverse  stock  split  and  the 
reincorporation  of  CRS  as  a  Delaware  corporation  under  the  name  Rexahn  Pharmaceuticals,  Inc. 
("Rexahn  Pharmaceuticals"),  on  May  13,  2005,  Merger  Sub  merged  with  and  into  Rexahn,  with 
Rexahn  surviving  as  a  wholly  owned  subsidiary  of  Rexahn  Pharmaceuticals  (the  "Acquisition 
Merger"). In the Acquisition Merger, (i) each share of the issued and outstanding common stock of 
Rexahn (other than dissenting shares) was converted into the right to receive five shares of Rexahn 
Pharmaceuticals common stock; and (ii) each issued, outstanding and unexercised option to purchase 
a  share  of  Rexahn  common  stock  was  converted  into  an  option  to  purchase  five  shares  of  Rexahn 
Pharmaceuticals common stock. 

Shares  of  Rexahn  Pharmaceuticals  common  stock  issued  in  the  Acquisition  Merger  were  exempt 
from the registration requirements of the Securities Act of 1933, as amended (the "Securities Act"), 
pursuant  to  Regulation  D  under  the  Securities  Act  and/or  Regulation  S  under  the  Securities  Act. 
These shares of Rexahn Pharmaceuticals common stock are deemed "restricted securities" and bear 
an appropriate restrictive legend indicating that the resale of such shares may be made only pursuant 
to registration under the Securities Act or pursuant to an available exemption from such registration. 
For accounting purposes, the Acquisition Merger is accounted for as a reverse acquisition of CRS 
(legal acquirer) by Rexahn (accounting acquirer).  As a result, following the Acquisition Merger, the 
historical financial statements of Rexahn became the historical financial statements of the Company. 

On  September  29,  2005,  the  Company's  wholly  owned  subsidiary,  Rexahn,  was  merged  with  and 
into the Company and Rexahn's separate existence was terminated. 

2.  Summary of Significant Accounting Policies 

a)  Cash and Cash Equivalents 

Cash  and  cash  equivalents  include  cash  on  hand  and  short-term  investments  purchased  with 
remaining maturities of three months or less at acquisition.

b)  Equipment 

Equipment is stated at cost less accumulated depreciation. Depreciation, based on the estimated 
useful lives of the assets, is provided as follows: 

Furniture and fixtures

straight line

c)  Research and Development 

Research  and  development  costs  are  expensed  as  incurred.    Research  and  development 
expenses  consist  primarily  of  salaries  and  related  personnel  costs,  as  well  as  stock 
compensation  related  to  these  costs,  costs  to  acquire  pharmaceutical  products  and  product 
rights  for  development  and  amounts  paid  to  contract  research  organizations,  hospitals  and 
laboratories for the provision of services and materials for drug development and clinical trials. 

Costs  incurred  in  obtaining  the  license  rights  to  technology  in  the  research  and  development 
stage and that have no alternative future uses are expensed as incurred. 

d)  Use of Estimates 

The  preparation  of  financial  statements  in  conformity  with  accounting  principles  generally 
accepted  in  the  United  States  requires  management  to  make  estimates  and  assumptions  that 
affect the reported amounts of assets and liabilities and the disclosure of contingent assets and 
liabilities  at  the  date  of  the  financial  statements  and  the  reported  amounts  of  revenues  and 
expenses  during  the  reporting  period.    These  estimates  are  based  on  management's  best 
knowledge  of  current  events  and  actions  the  Company  may  undertake  in  the  future.    Actual 
results may ultimately differ from those estimates.  These estimates are reviewed periodically 
and as adjustments become necessary, they are reported in earnings in the period in which they 
become available. 

e) 

Fair Value of Financial Instruments 

The  carrying  amounts  reported  in  the  accompanying  financial  statements  for  cash  and  cash 
equivalents,  prepaid  expenses  and  other  current  assets  and  accounts  payable  and  accrued 
expenses  approximate  fair  value  because  of  the  short-term  maturity  of  these  financial 
instruments. 

f) 

Income Taxes 

The  Company  accounts  for  income  taxes  pursuant  to  Statement  of  Financial  Accounting 
Standards  ("SFAS")  No.  109,  "Accounting  for  Income  Taxes".    Deferred  tax  assets  and 
liabilities  are  recorded  for  differences  between  the  financial  statement  and  tax  basis  of  the 

47 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
REXAHN PHARMACEUTICALS, INC. 
(A Development Stage Company) 
Notes to Financial Statements 
Years Ended December 31, 2007 and 2006 

assets  and  liabilities  that  will  result  in  taxable  or  deductible  amounts  in  the  future  based  on 
enacted  tax  laws  and  rates.    Valuation  allowances  are  established  when  necessary  to  reduce 
deferred tax assets to the amount expected to be realized.  Income tax expense is recorded for 
the amount of income tax payable or refundable for the period, increased or decreased by the 
change in deferred tax assets and liabilities during the period. 

On  January 1,  2007,  the  Company  adopted  Financial  Accounting  Standards  Board  (FASB) 
Interpretation  No. 48,  “Accounting  for  Uncertainty  in  Income  Taxes—an  interpretation  of 
FASB  Statement  No. 109”  (FIN  48). There  was  no  impact  on  the  Company’s  consolidated 
financial position, results of operations or cash flows at December 31, 2007 and for the year 
then ended as a result of implementing FIN 48. At the adoption date of January 1, 2007 and at 
December 31, 2007, the Company did not have any unrecognized tax benefits. The Company’s 
practice  is  to  recognize  interest  and/or  penalties  related  to  income  tax  matters  in  income  tax 
expense. As of January 1, 2007 and December 31, 2007, the Company had no accrued interest 
or penalties. The Company currently has no federal or state tax examinations in progress nor 
has  it  had  any  federal  or  state  tax  examinations  since  its  inception.  As  a  result  of  the 
Company’s net operating loss carryforwards, all of its tax years are subject to federal and state 
tax examination. 

g)   Net Loss Per Common Share: 

The  Company  accounts  for  earnings  per  share  pursuant  to  SFAS  No.  128,  "Earnings  per 
Share", which requires disclosure on the financial statements of "basic" and "diluted" earnings 
(loss) per share.  Basic earnings (loss) per share is computed by dividing net income (loss) by 
the  weighted  average  number  of  common  shares  outstanding  for  the  year.    Diluted  earnings 
(loss) per share is computed by dividing net income (loss) by the weighted average number of 
common  shares  outstanding  plus  potentially  dilutive  securities  outstanding  for  each  year. 
Potentially dilutive securities include stock options and warrants and shares of common stock 
issuable upon conversion of the Company's convertible notes. 

For purpose of computing diluted earnings per share, 3,283,800 common share equivalents for 
the  year  ended,  December  31,  2007  and  2,788,230  common  share  equivalents  for  the  year 
ended, December 31, 2006, were excluded from the calculation of diluted earnings per share 
because their inclusion would have been anti-dilutive as a result of the net loss applicable to 
these periods. 

h) 

Stock-Based Compensation 

Effective  January  1,  2006,  the  Company’s  Plan  is  accounted  for  in  accordance  with  the 
recognition  and  measurement  provisions  of  Statement  of  Financial  Accounting  Standards 
("FAS") No. 123 (revised 2004), Share-Based Payment ("FAS 123(R)"), which replaces FAS 
No.  123,  Accounting  for  Stock-Based  Compensation,  and  supersedes  Accounting  Principles 
Board  Opinion  ("APB")  No.  25,  Accounting  for  Stock  Issued  to  Employees,  and  related 
interpretations.  FAS  123(R)  requires  compensation  costs  related  to  share-based  payment 
transactions, including employee stock options, to be recognized in the financial statements. In 
addition,  the  Company  adheres  to  the  guidance  set  forth  within  Securities  and  Exchange 
Commission  ("SEC")  Staff  Accounting  Bulletin  No.  107  ("SAB  107"),  which  provides  the 

48 

 
 
 
 
 
 
 
 
 
REXAHN PHARMACEUTICALS, INC. 
(A Development Stage Company) 
Notes to Financial Statements 
Years Ended December 31, 2007 and 2006 

Staff's  views  regarding  the  interaction  between  SFAS  No.  123(R)  and  certain  SEC  rules  and 
regulations and provides interpretations with respect to the valuation of share-based payments 
for public companies.  See footnote 7 for further details. 

i) 

Impairment of Long-Lived Assets 

In accordance with SFAS No. 144, "Accounting for the Impairment or Disposal of Long-Lived 
Assets", long-lived assets to be held and used are analyzed for impairment whenever events or 
changes  in  circumstances  indicate  that  the  related  carrying  amounts  may  not  be  recoverable.  
The  Company  evaluates  at  each  balance  sheet  date  whether  events  and  circumstances  have 
occurred  that  indicate  possible  impairment.    If  there  are  indications  of  impairment,  the 
Company uses future undiscounted cash flows of the related asset or asset grouping over the 
remaining life in measuring whether the assets are recoverable.  In the event such cash flows 
are  not  expected  to  be  sufficient  to  recover  the  recorded  asset  values,  the  assets  are  written 
down  to  their  estimated  fair  value.    Long-lived  assets  to  be  disposed  of  are  reported  at  the 
lower of the carrying amount or the fair value of the asset less costs of selling. 

j)  Concentration of Credit Risk 

SFAS  No.  105,  "Disclosure  of  Information  About  Financial  Instruments  with  Off-Balance 
Sheet Risk and Financial Instruments with Concentration of Credit Risk", requires disclosure 
of any significant off-balance sheet risk and credit risk concentration.  The Company does not 
have significant off-balance sheet risk or credit concentration.  The Company maintains cash 
and short-term investments with major financial institutions.  From time to time the Company 
has funds on deposit with commercial banks that exceed federally insured limits ("FDIC") of 
$100,000.  Management does not consider this to be a significant credit risk as these banks and 
financial institutions are well-known. At December 31, 2007 the Company had a cash balance 
of $7,259,571 in excess of FDIC limits. 

k)  Recent Accounting Pronouncements Affecting the Company: 

In  September  2006,  the  staff  of  the  SEC  issued  Staff  Accounting  Bulletin  ("SAB")  No.  108, 
which provides interpretive guidance on how the effects of the carryover or reversal of prior 
year misstatements should be considered in quantifying a current year misstatement. SAB 108 
became effective in fiscal year end December 31, 2007. Adoption of SAB 108 did not have a 
material impact on the Company's financial position, results of operations or cash flows. 

In December 2006, the FASB issued FASB Staff Position ("FSP") EITF 00-19-2 "Accounting 
for  Registration  Payment  Arrangements"  ("FSP  EITF  00-19-2")  which  specifies  that  the 
contingent  obligation  to  make  future  payments  or  otherwise  transfer  consideration  under  a 
registration payment arrangement should be separately recognized and measured in accordance 
with  SFAS  No.  5,  "Accounting  for  Contingencies."  Adoption  of  FSP  EITF  00-19-02  is 
required  for  fiscal  years  beginning  after  December  15,  2006,  and  did  not  have  a  material 
impact on the Company's financial position, results of operations or cash flows. 

In September 2006, the FASB issued SFAS No. 157, Fair Value Measurements, which defines 
fair value, establishes a framework for measuring fair value in generally accepted accounting 

49 

 
 
 
 
 
 
 
 
 
 
REXAHN PHARMACEUTICALS, INC. 
(A Development Stage Company) 
Notes to Financial Statements 
Years Ended December 31, 2007 and 2006 

principles,  and  expands  disclosures  about  fair  value  measurements.  This  statement  does  not 
require any new fair value measurements, but provides guidance on how to measure fair value 
by  providing  a  fair  value  hierarchy  used  to  classify  the  source  of  the  information.  SFAS 
No. 157 is effective for fiscal years beginning after November 15, 2007, and all interim periods 
within those fiscal years. In December 2007, the FASB released a FASB Staff Position (FSP 
FAS 157-b - Effective Date of FASB Statement No. 157) which, delays the effective date of 
SFAS  No. 157  for  all  nonfinancial  assets  and  nonfinancial  liabilities,  except  those  that  are 
recognized or disclosed at  fair value in  the financial  statements on a recurring basis (at least 
annually). We do not believe that adoption of this statement would have a material impact on 
our financial statements. 

In  February  2007,  the  FASB  issued  SFAS  No.  159,  “The  Fair  Value  Option  for  Financial 
Assets and Financial Liabilities” (“SFAS No. 159”). SFAS No. 159 permits entities to choose 
to measure, on an item-by-item basis, specified financial instruments and certain other items at 
fair  value.  Unrealized  gains  and  losses  on  items  for  which  the  fair  value  option  has  been 
elected  are  required  to  be  reported  in  earnings  at  each  reporting  date.  SFAS  No.  159  is 
effective  for  fiscal  years  beginning  after  November  15,  2007,  the  provisions  of  which  are 
required to be applied prospectively. The Company expects to adopt SFAS No. 159 in the first 
quarter  of  Fiscal  2008  and  is  still  evaluating  the  effect,  if  any,  on  its  financial  position  or 
results of operations.   

In June 2007, the EITF Issue 07-03, “Accounting for Advance Payments for Goods or Services 
to  Be  Used  in  Future  Research  and  Development”  (EITF  07-03).  EITF  07-03  addresses  the 
diversity  which  exists  with  respect  to  the  accounting  for  the  non-refundable  portion  of  a 
payment  made  by  a  research  and  development  entity  for  future  research  and  development 
activities.  Under  EITF  07-03,  an  entity  would  defer  and  capitalize  non-refundable  advance 
payments made for research and development activities until the related goods are delivered or 
the  related  services  are  performed.  EITF  07-03  is  effective  for  fiscal  years  beginning  after 
December 15,  2007  and  interim  periods  within  those  years.  The  Company  is  currently 
evaluating the potential impact from adopting EITF 07-03 on the financial position or results of 
operations. 

In December 2007, the Financial Accounting Standards Board (“FASB”) issued Statement of 
Financial  Accounting  Standards  (“SFAS”)  No. 141  (revised  2007),  Business  Combinations, 
which  replaces  SFAS  No  141.  The  statement  retains  the  purchase  method  of  accounting  for 
acquisitions,  but  requires  a  number  of  changes,  including  changes  in  the  way  assets  and 
liabilities are recognized in the purchase accounting. It also changes the recognition of assets 
acquired  and  liabilities  assumed  arising  from  contingencies,  requires  the  capitalization  of  in-
process  research  and  development  at  fair  value,  and  requires  the  expensing  of  acquisition-
related costs as incurred. SFAS No. 141R is effective for 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. 

In  December  2007,  the  FASB  issued  SFAS  No.  160.    “Noncontrolling  Interests  in 
Consolidated Financial Statements-and Amendment of ARB No. 51.”  SFAS 160 establishes 
accounting  and  reporting  standards  pertaining  to  ownership  interests  in  subsidiaries  held  by 
parties  other  than  the  parent,  the  amount  of  net  income  attributable  to  the  parent  and  to  the

noncontrolling  interest,  changes  in  a  parent’s  ownership  interest,  and  the  valuation  of  any 
retained noncontrolling equity investment when a subsidiary is deconsolidated.  This statement 
also  establishes  disclosure  requirements  that  clearly  identify  and  distinguish  between  the 
interests of the parent and the interests of the noncontrolling owners.  SFAS 160 is effective 
for fiscal years beginning on or after December 15, 2008.  The adoption of SFAS 160 is not 
currently  expected  to  have  a  material  effect  on  the  Company’s  financial  position,  results  of 
operations, or cash flows. 

In  March  2008,  the  Financial  Accounting  Standards  Board  (FASB)  issued  FASB  Statement 
No. 161, Disclosures about Derivative Instruments and Hedging Activities. The new standard 
is intended to improve financial reporting about derivative instruments and hedging activities 
by requiring enhanced disclosures to enable investors to better understand their effects on an 
entity’s  financial  position,  financial  performance,  and  cash  flows.  It  is  effective  for  financial 
statements issued for fiscal years and interim periods beginning after November 15, 2008, with 
early  application  encouraged.  The  company  is  currently  evaluating  the  impact  of  adopting 
SFAS. No. 161 on its financial statements.

Intangible Asset 

into  a 

the  Company  entered 

licensing  agreement  with  Revaax 
On  February  10,  2005, 
Pharmaceuticals LLC ("Revaax"), whereby the Company received an exclusive, worldwide, royalty 
bearing  license,  with  the  right  to  sub-license  Revaax's  licensed  technology  and  products.    The 
agreement called for an initial licensing fee of $375,000 to be payable to Revaax in eight quarterly 
installments ending on November 10, 2006.  Accordingly, the Revaax license has been measured at 
fair  value  at  the  date  the  licensing  agreement  was  entered  into.    The  fair  value  of  the  license 
component of $356,216  was determined by discounting the stream of future quarterly payments of 
$46,875  at  6%,  the  prevailing  market  rate  for  a  debt  instrument  of  comparable  maturity  and  credit 
quality.  The asset is amortized on a straightline basis over an estimated useful life of 20 years.  The 
discount  was  accreted  over  the  term  of  the  liability,  calculated  based  on  the  Company's  estimated 
effective market interest rate of 6%.  During 2006 the outstanding balance was paid.  Amortization 
expense was  $18,028 and $17,919 for the years ended December 31, 2007 and 2006, respectively. 
Management does not believe that there is an impairment of intangible assets at December 31, 2007.

5.  Deferred Revenue 

In 2003, the Company entered into a collaborative research agreement with Rexgene Biotech Co., 
Ltd.  ("Rexgene"),  a  minority  shareholder. 
  Rexgene  is  engaged  in  the  development  of 
pharmaceutical  products  in  Asia  and  has  agreed  to  assist  the  Company  with  the  research, 
development  and  clinical  trials  necessary  for  registration  of  the  Company's  drug  candidate, 
RX-0201,  in Asia.    This  agreement  provides  Rexgene  with  exclusive  rights  to license,  sublicense, 
make,  have  made,  use,  sell  and  import  RX-0201  in  Asia.  A  one-time  contribution  to  the  joint 
development  and  research  of  RX-0201  of  $1,500,000  was  paid  to  the  Company  in  2003  in 
accordance with the agreement.  The amount of revenue from this contribution is being recognized 
as income over the term of the agreement which terminates at the later of 20 years or the term of the 
patent  on  the  licensed  product.  The  Company  is  using  20  years  as  its  basis  for  recognition  and 
accordingly  $75,000  was  included  in  revenues  for  the  years  ended  December  31,  2007  and  2006.  
The remaining $1,125,000 at December 31, 2007 (2006-$1,200,000) is reflected as deferred revenue 
on the balance sheet.  The Company adopted SAB No. 104, "Revenue Recognition Nonrefundable 
Up-front Fees" with respect to the accounting for this transaction. These fees are being used in the 
cooperative  funding  of  the  costs  of  development  of  RX-0201.    Royalties  of  3%  of  net  sales  of 
licensed products will become payable to the Company on a quarterly basis once commercial sales 
of RX-0201 begin. The product is still under development and commercial sales are not expected to 
begin until 2009. 

6.  Stockholders’ Equity Transactions

Stock-Based Compensation 

On August 5, 2003, the Company established a stock option plan (the “Plan”).  Under the Plan, the 
Company grants stock options to key employees, directors and consultants of the Company.  For all 
grants  prior  to  September  12,  2005  and  grants  to  employees  of  the  Company  after  September  12, 
2005, the vesting period is 30% on the first anniversary of the grant date, an additional 30% on the 
second anniversary and the remaining 40% on the third anniversary.  Options expire between 5 and 
10 years from the date of grant. 

For grants to non-employee directors and consultants of the Company after September 12, 2005, the 
vesting  period  is  between  1  to  3  years,  subject  to  the  fulfillment  of  certain  conditions  in  the 
individual stock option grant agreements, or 100% upon the occurrence of certain events specified in 
the individual stock option grant agreements.  Options authorized for issuance under the Plan total 
17,000,000 after giving effect to an amendment to the Plan approved at the Annual Meeting of the 
Stockholders of the Company on June 2, 2006 and at December 31, 2007, 10,670,000 options were 
available for issuance. 

Prior to adoption of the plan, the Company made restricted stock grants.  During 2003 all existing 
restricted stock grants were converted to stock options.  The converted options maintained the same 
full vesting period as the original restricted stock grants. 

Accounting for Employee Awards 

Effective  January  1,  2006,  the  plan  is  accounted  for  in  accordance  with  the  recognition  and 
measurement provisions of SFAS No. 123R, which replaces SFAS No. 123 and supersedes APB  

The  Company's  results  of  operations  for  the  years  ended  December  31,  2007  and  2006  include 
share-based  employee  compensation  expense  totaling  $596,097  and  $656,169,  respectively.  Such 
amounts  have  been  included  in  the  Statements  of  Operations  in  general  and  administrative  and 
research and development expenses.  No income tax benefit has been recognized in the Statements 
of Operations for share-based compensation arrangements as the Company has provided for a 100% 
valuation allowance on its deferred tax assets. 

Employee stock option compensation expense in 2007 is the estimated fair value of options granted 
which are recognized on a straight-line basis over the requisite service period for the entire portion 
of  the  award.  The  Company  has  not  adjusted  the  expense  by  estimated  forfeitures,  as  required  by

REXAHN PHARMACEUTICALS, INC.

SFAS  No.  123R  for  employee  options,  since  the  forfeiture  rate  based  upon  historical  data  was 
determined to be immaterial. 

Accounting for Non-Employee Awards 

The  Company  previously  accounted  for  options  granted  to  its  non-employee  consultants  and  non-
employee registered representatives using the fair value cost in accordance with SFAS No. 123 and  
EITF  96-18.    The  adoption  of  SFAS  No.  123R  and  SAB  No.  107,  as  of  January  1,  2006,  had  no 
material impact on the accounting for non-employee awards.  The Company continues to consider 
the additional guidance set forth in EITF Issue No. 96-18.  

Stock  compensation  expense  related  to  non-employee  options  was  $525,549  for  the  year  ended 
December 31, 2007, respectively, and $377,787 for the year ended December 31, 2006.   

Such amounts have been included in the Statements of Operations in general and administrative and 
research and development expenses. 

Total stock-based compensation recognized by the Company in the years ended December 31, 2007 
and  2006,  and  the  period  from  inception  (March  19,  2001)  to  December 31,  2007,  all  of  which 
relates to stock options and warrants, is as follows:

The fair value of options at the date of grant was estimated using the Black-Scholes option pricing 
model.  During  2007,  the  Company  took  into  consideration  guidance  under  SFAS  No.  123(R)  and 
SAB  No.  107  when  reviewing  and  updating  assumptions.  The  expected  volatility  is  based  upon

As  of  December  31,  2007  and  2006,  there  was  $1,410,269  and  $2,242,525  of  total  unrecognized 
compensation  cost,  respectively,  related  to  all  unvested  stock  options,  which  is  expected  to  be 
recognized over a weighted average vesting period of 1.2 years and 1.8 years, respectively.   

8. 

Income Taxes 

No provision for Federal or state income taxes was required for the years ended December 31, 2007 
or 2006, due to the Company’s operating losses.  At December 31, 2007 and 2006, the Company has 
unused  net  operating  loss  carry-forwards  of  approximately  $  24,994,000  and  $20,838,000  which 
expire  at  various  dates  through  2027.    Most  of  this  amount  is  subject  to  annual  limitations  under 
certain provisions of the Internal Revenue Code related to “changes in ownership”. 

As  of  December  31,  2007  and  2006,  the  deferred  tax  assets  related  to  the  aforementioned  carry-
forwards have been fully offset by valuation allowances, since significant utilization of such amounts 
is not presently expected in the foreseeable future.   

Deferred tax assets and valuation allowances consist of: 

  Net operating loss carry-forwards  
  Valuation allowance 
  Net deferred tax assets

taxing authorities. 

9.  Commitments and Contingencies 

a)  The  Company  has  contracted  with  various  vendors  to  provide  research  and  development 
services.  The  terms  of  these  agreements  usually  require  an  up-front  payment  and  monthly  or 
periodic payments over the terms of the agreement, ranging from 6 months to 24 months. The 
costs  to  be  incurred  are  estimated  and  are  subject  to  revision.  As  of  December  31,  2007,  the 
total  value  of  these  agreements  was  approximately  $1,972,000  and  the  Company  had  made 
payments totaling $1,353,000 under the terms of the agreements as at December 31, 2007.  All 
of these agreements may be terminated by either party upon appropriate notice as stipulated in 
the respective agreements. 

b)    The Company and two of its key executives entered into employment agreements. One of the 
two agreements was renewed on September 12, 2007 and results in an annual commitment of 
$160,000 and expires September 12, 2009. One agreement expires on September 12, 2010 and 
results in an annual commitment of $350,000.

c) 

In  April  2004,  the  Company  signed  a  5  year  lease  for  8,030  square  feet  of  office  space  in 
Rockville, Maryland commencing July 2004. The lease requires annual base rents of $200,750 
subject to annual increases of 3% of the preceding years adjusted base rent. Under the leasing 
agreement, the Company also pays its allocable portion of real estate taxes and common area 
operating charges. 

   Minimum future rental payments under this lease as of December 31, 2007 are as follows: 

2008

$  222,655 
    112,973 
$  335,628 

d)  Regulation by governmental authorities in the United States and in other countries constitutes a 
significant consideration in our product development, manufacturing and marketing strategies. 
The  Company  expects  that  all  of  drug  candidates  will  require  regulatory  approval  by 
appropriate governmental agencies prior to commercialization and will be subjected to rigorous 
pre-clinical,  clinical,  and  post-approval  testing,  as  well  as  to  other  approval  processes  by  the 
FDA  and  by  similar  health  authorities  in  foreign  countries.  United  States  federal  regulations 
control the ongoing safety, manufacture, storage, labeling, record keeping, and marketing of all 
biopharmaceutical products intended for therapeutic purposes. The Company believes that it is 
in compliance in all material respects with currently applicable rules and regulations. 

e)  On March 5, 2007, the Company entered into an agreement with Rx Communications Group 
LLC  (“Rx”)  for  Rx  to  provide  investor  relations  services  to  the  Company.  Under  this 
agreement,  the  Company  agreed  to  pay  Rx  a  monthly  fixed  retainer  amount  of  $10,000 
commencing  March  1,  2007.    In  accordance  with  the  agreement,  the  contract  may  be 
terminated  by  either  party  upon  thirty  (30)  days  prior  written  notice  to  the  other  party.    On 
November  1,  2007,  the  Company  entered  into  an  amendment  of  the  agreement  with  Rx  to 
provide investor relations services.  Under the amended agreement, the company agreed to pay 
Rx compensation for services at hourly rates commencing November 1, 2007.  In accordance 
with the agreement, the contract may be terminated by either party upon thirty (30) days prior 
written notice to the other party.   

f)  On May 30, 2007, the Company engaged Rodman and Renshaw, LLC (“Rodman”) to serve as 
the placement agent in connection with the proposed offer and placement of securities of the 
Company.  Pursuant  to  the  agreement,  the  Company  shall  pay  Rodman  a  cash  placement  fee 
equal to 7% of the aggregate proposed offering.  

10.  Subsequent Events 

a) 

During  January  2008,  50,000  stock  options  were  cancelled  due  to  termination  of 
employment of an employee.

Item 8. Changes In and Disagreements With Accountants on Accounting and Financial 
Disclosure 

Not applicable. 

Item 8A.  Controls and Procedures 

Evaluation  of  Disclosure  Controls  and  Procedures.  Under  the  supervision  and  with  the 
participation of our management, including our Chief Executive Officer and Chief Financial Officer, we 
evaluated  the  effectiveness  of  the  design  and  operation  of  our  disclosure  controls  and  procedures  (as 
defined  in  Rule  13a-15(e)  and  15d-15(e)  under  the  Securities  Exchange  Act  of  1934  (the  “Exchange 
Act”)) as of the end of the period covered by this report. Based upon that evaluation, our Chief Executive 
Officer and Chief Financial Officer concluded that our disclosure controls and procedures as of the end of 
the period covered by this report were effective such that the information required to be disclosed by us in 
reports  filed  under  the  Securities  Exchange  Act  of  1934  is  (i) recorded,  processed,  summarized  and 
reported  within  the  time  periods  specified  in  the  SEC’s  rules  and  forms  and  (ii) accumulated  and 
communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as 
appropriate  to  allow  timely  decisions  regarding  disclosure.  A  controls  system  cannot  provide  absolute 
assurance, however, that the objectives of the controls system are met, and no evaluation of controls can 
provide absolute assurance that all control issues and instances of fraud, if any, within a company have 
been detected. 

Management’s Annual Report on Internal Control over Financial Reporting.  Our management is 
responsible for establishing and maintaining adequate internal control over financial reporting (as defined 
in  Rule 13a-15(f)  under  the  Exchange  Act).  Our  internal  control  over  financial  reporting  is  a  process 
designed  to  provide  reasonable  assurance  regarding  the  reliability  of  financial  reporting  and  the 
preparation  of  financial  statements  for  external  purposes  of  accounting  principles  generally  accepted  in 
the United States.  

Because  of  its  inherent  limitations,  internal  control  over  financial  reporting  may  not  prevent  or 
detect  misstatements.  Therefore,  even  those  systems  determined  to  be  effective  can  provide  only 
reasonable assurance of achieving their control objectives.  

Our management, with the participation of the Chief Executive Officer and Chief Financial Officer, 
evaluated the effectiveness of the Company’s internal control over financial reporting as of December 31, 
2007.  Based  on  this  evaluation,  our  management,  with  the  participation  of  the  Chief  Executive  Officer 
and Chief Financial Officer, concluded that, as of December 31, 2007, our internal control over financial 
reporting was effective. 

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

Changes  in  Internal  Control  Over  Financial  Reporting.  During  the  most  recent  quarter  ended

December 31, 2007, there has been no change in our internal control over financial reporting (as defined 
in Rule 13a-15(f) and 15d-15(f) under the Exchange Act) ) that has materially affected, or is reasonably 
likely to materially affect, our internal control over financial reporting.

CODE OF ETHICS AND BUSINESS CONDUCT 

Exhibit 14 

The  Board  of  Directors  (the  “Board”)  of  Rexahn  Pharmaceuticals,  Inc.  ("Rexahn"  or  the  "Company") 
maintains policies and procedures (which we refer to as the “Code”) that represent both the code of ethics 
for  the  principal  executive  officer,  principal  financial  officer  and  principal  accounting  officer  under 
Securities and Exchange  Commission  rules,  and a  more general code of business  conduct  and ethics for 
members  of  the  Board  (the  “Directors”),  officers  and  employees.    The  Code  applies  to  all  Directors, 
officers and employees. 

The  Code  is  posted  on  the  Company’s  Internet  web  site  at  www.rexahn.com  and  is  available  free  of 
charge by calling the Company at (240) 268-5300 or by writing to: 

Rexahn Pharmaceuticals, Inc. 
Attn:  General Counsel 
9620 Medical Center Drive 
Rockville, MD 20850 

The  Code  will  also  be  filed  as  an  exhibit  to  the  Company’s  Annual  Report  on  Form  10-KSB.    Any 
amendment to the Code will be promptly posted on the Company’s Internet web site. 

The Audit Committee of the Board (the “Audit Committee”) is authorized to review any issues under the 
Code, retain legal counsel and report its findings to the Board.  The Board does not envision that any 
waivers  of  the  Code  will  be  granted,  but  should  a  waiver  be  granted  for  any  Director  or  executive 
officer, it will also be promptly disclosed on the Company’s Internet web site. 

The  Code  consists  of  the  Ethics  Policy,  the  Conflicts  of  Interest/Corporate  Opportunity  Policy,  the 
Corporate Assets Policy, the Directorships Policy, the Procedures and Open Door Communication Policy 
and the Enforcement Policy. 

The Code follows: 

Ethics Policy 

It is the policy of Rexahn to comply with all governmental laws, rules and regulations applicable to its 
business. 

The Company’s Ethics policy does not stop there.  Even where the law is permissive, the Company prefers the 
course of highest integrity.  Local customs, traditions and mores differ from place to place, and this must be 
recognized.  But honesty is not subject to criticism in any culture.  A well-founded reputation for scrupulous 
dealing is itself a priceless corporate asset. 

The  Company  cares  how  results  are  obtained,  not  just  that  they  are  obtained.    Directors,  officers  and 
employees should deal fairly with each other, with the Company’s customers and with other third parties. 

The Company expects compliance with its standard of integrity throughout the organization and will not 
tolerate  employees  who  achieve  results  at  the  cost  of  violation  of  law  or  this  Code.    The  Company’s 
Directors and officers support, and expect the Company’s employees to support, any employee that passes 
up an opportunity or advantage that would sacrifice ethical standards. 

 
  
 
Exhibit 14 

It  is  the  Company’s  policy  that  all  transactions  will  be  accurately  reflected  in  its  books  and  records.  
This, of course, means that falsification of books and records and the creation or maintenance of any off-
the-record bank account is strictly prohibited.  Employees are required to record all transactions accurately in 
the  Company’s  books  and  records,  and  to  be  honest  and  forthcoming  with  the  Company’s  internal  and 
independent auditors. 

The  Company  expects  candor  from  employees  at  all  levels  and  adherence  to  its  policies  and  internal 
controls.    One  harm  that  results  when  employees  conceal  information  from  higher  management  or  the 
auditors is that other employees think they are being given a signal that the Company’s policies and internal 
controls can be ignored when they are inconvenient.  That can result in corruption and demoralization of an 
organization.  The Company’s system of management will not work without honesty. 

It is the Company’s policy to make full, fair, accurate, timely and understandable disclosure in reports 
and documents that the Company files with the Securities and Exchange Commission and in other public 
communications.  All  employees are responsible for reporting relevant material information known to 
them  to  higher  management  so  that  the  information  will  be  available  to  senior  executives  responsible  for 
making disclosure decisions. 

Conflicts of Interest/Corporate Opportunity Policy 

It  is  the  policy  of  Rexahn  that  Directors,  officers  and  employees  are  expected  to  avoid  any  actual  or 
apparent  conflict  between  their  own  personal  interests  and  the  interests  of  the  Company.    A  conflict  of 
interest  can  arise  when  a  Director,  officer  or  employee  takes  actions  or  has  personal  interests  that  may 
interfere with the effective performance  of work for the Company.  For example, Directors, officers and 
employees are required to avoid actual or apparent conflicts in dealings with suppliers, customers, competitors 
and  other  third  parties.    Directors,  officers  and  employees  are  required  to  refrain  from  taking  for 
themselves opportunities discovered through their use of corporate assets or information or through their 
positions with the Company and are prohibited from using corporate property, information, or position for 
personal  gain.    Directors,  officers  and  employees  are  required  to  avoid  securities  transactions  based  on 
material, nonpublic information learned through their positions with the Company.  Directors, officers and 
employees are required to refrain from competing with the Company. 

Corporate Assets Policy 

It is the policy of Rexahn that Directors, officers and employees are expected to protect the assets of the 
Company and use them efficiently to advance the Company’s interests.  Those assets include tangible assets 
and  intangible  assets,  such  as  confidential  information  of  the  Company.    No  Director,  officer  or  employee 
should  use  or  disclose  at  any  time  during  or  subsequent  to  employment  or  other  service  to  the 
Company, without proper authority or mandate, confidential information obtained from any source in the 
course  of  the  Company’s  business.    Examples  of  confidential  information  include  nonpublic 
information  about  the  Company’s  business,  plans,  earnings,  financial  forecasts,  business  forecasts, 
discoveries, competitive bids, technologies and personnel. 

Directorships Policy 

It is the policy of Rexahn to restrict the holding by officers and employees of directorships in nonaffiliated 
for-profit  organizations  and  to  prohibit  the  acceptance  by  any  officer  or  employee  of  such  directorships 
that could involve a conflict of interest with, or interfere with, the discharge of the officer’s or employee’s 
duties  to  the  Company.    Any  officer  or  employee  may  hold  directorships  in  nonaffiliated  non-profit 
organizations,  unless  such  directorships  would  involve  a  conflict  of  interest  with,  or  interfere  with,  the 
discharge  of  the  officer’s  or  employee’s  duties  to  the  Company,  or  obligate  the  Company  to  provide 

 
  
Exhibit 14 

support  to  the  nonaffiliated  non-profit  organizations.    Officers  and  employees  may  serve  as  directors  of 
affiliated companies and such service may be part of their normal work assignments. 

All directorships in public companies held by Company Directors are subject to review and approval by 
the Board.  In all other cases, directorships in nonaffiliated, for-profit organizations are subject to review and 
approval by the management of the Company, as directed by the Company’s Chairman of the Board. 

Procedures and Open Door Communication Policy 

Rexahn  encourages  employees  to  ask  questions,  voice  concerns  and  make  appropriate  suggestions 
regarding  the  business  practices  of  the  Company.    Employees  are  expected  to  report  promptly  to 
management suspected violations of law, the Company’s policies and internal controls, so that management 
can take appropriate corrective action.  The intent of the Company is to investigate promptly reports of 
suspected violations of law, policies and internal control procedures. 

Management and the Audit Committee are ultimately responsible for the investigation of and appropriate 
response  to  reports  of  suspected  violations  of  law,  policies  and  internal  control  procedures.    The 
Company’s Internal Audit Department has primary responsibility for investigating violations of internal 
controls, with assistance from others, depending on the subject matter of the inquiry.  The persons who 
investigate suspected violations are expected to exercise independent and objective judgment.  Towards 
this  end,  most  investigations  will  be  conducted  by  outside  legal  counsel  at  the  direction  of  the  Audit 
Committee. 

Normally,  an  employee  should  first  discuss  suspected  violations  of  law,  policies  or  internal  control 
procedures,  with  the  employee’s  immediate  supervisor.    Each  supervisor  is  expected  to  be  available  to 
subordinates  for  that  purpose.    If  an  employee  is  dissatisfied  following  such  a  discussion  with  the 
employee’s immediate supervisor, the employee is encouraged to request further reviews, in the presence of 
the supervisor or otherwise.  Reviews should continue to the level of management appropriate to resolve 
the issue. 

Depending  on  the  circumstances  and/or  subject  matter  of  the  question,  concern  or  suggestion,  each 
employee also has access to alternate channels of communication, including, for example, the Internal Audit 
Department; the Human Resources Department; the Office of the Treasurer; and the General Counsel.  

Suspected violations of law or the Company’s policies involving a Director or executive officer, as well as 
any  concern  regarding  questionable  accounting  or  auditing  matters,  should  be  referred  directly  to  the 
Audit Committee and the General Counsel.  The Audit Committee is authorized to review and direct the 
investigation of all issues involving Directors or executive officers, and, in its sole discretion, may refer 
any or all such issues to the Board. 

Employees  may  also  address  communications  to  individual  non-employee  directors  or  to  the  non-
employee  directors  as  a  group  by  writing  them  at  c/o  Hwan  Kim,  1200  New  Hampshire  Ave.  NW, 
Washington, D.C. 20036, or such other address as the Company may designate and publish from time to 
time. 

Employees  wishing  to  make  complaints  without  identifying  themselves  may  do  so  by  telephoning  the 
Company’s  Ethics  and  Compliance  Hotline  at  202-974-5690,  or  by  writing  the  General  Counsel  at  the 
address first listed above, or at such other telephone numbers, names and addresses as the Company may 
designate and publish from time to time.  All complaints to those telephone numbers and addresses concerning 
accounting, internal accounting controls or auditing matters will be referred to the Audit Committee. 

 
  
Exhibit 14 

All  persons  responding  to  employees’  questions,  concerns,  complaints  and  suggestions  are  expected  to 
use appropriate discretion regarding anonymity and confidentiality, although the preservation of anonymity 
and  confidentiality  may  or  may  not  be  practical,  depending  on  the  circumstances.    For  example, 
investigations of significant complaints typically necessitate revealing to others information about the 
complaint  and  complainant.    Similarly,  disclosure  can  result  from  government  investigations  and 
litigation. 

No action may be taken or threatened against any employee for asking questions, voicing concerns, or making 
complaints or suggestions in conformity with the procedures described above, unless the employee acts 
with willful disregard of the truth. 

All employees must cooperate fully with any and all investigations relating to a potential violation  of  this 
Code.    Such  cooperation  shall  include,  without  limitation,  being  accessible  to  answer  questions, 
disclosing relevant information and generally aiding the investigation in any reasonable manner requested. 

Failure  to  behave  honestly,  and  failure  to  comply  with  law,  the  Company’s  policies  and  internal  controls, 
including cooperating fully with any and all investigations, may each result in disciplinary action, up to and 
including termination. 

Only the Board or the Audit Committee has the authority to make exceptions or grant waivers to these 
policies.  If there is an exception or waiver granted, the Board or the Audit Committee will specifically 
find that such a waiver or exception is warranted and is being granted and shall promptly disclose such 
information to shareholders.  In those instances where the Company, through the Audit Committee or 
directly  through  the  Board  after  review,  approves  an  activity  or  situation,  including  without 
limitation  a  related  party  transaction,  without  specifically  citing  a  waiver  or  exception  to  these 
policies,  the  Company  is  not  granting  an  exception  or  waiver  but  is  determining  that  there  is  no  policy 
violation.    It  is  recognized  that  there  will  be  questions  about  the  application  of  the  policies  to  specific 
activities  and  situations.    In  cases  of  doubt,  Directors,  officers  and  employees  are  expected  to  seek 
clarification  and  guidance.    If  the  Company  determines  that  there  is  or  would  be  a  policy  violation, 
appropriate action will be taken. 

Enforcement Policy 

Ultimate  responsibility  for  enforcement  of  the  Code  shall  lie  with  the  Audit  Committee.    The 
General Counsel of the Company, working at the direction of the Audit Committee, shall provide 
legal advice as to the interpretation of the Code.  The Audit Committee shall have the authority to 
direct Code investigations and take such actions as are necessary to end any conduct found to be in 
violation  of  the  Code.    No  inquiry  or  investigation  shall  be  commenced  unless  authorized  and 
requested by the Audit Committee, which may instruct the General Counsel, an outside law firm or 
other unrelated entity or internal Company personnel to perform such inquiry or investigation.   

Please  note  that  the  Code  is  not  intended  to  and  does  not  create  a  contract  of  employment  between 
employees  and  the  Company,  and  compliance  with  the  Code  is  expected,  but  does  not  guarantee  that 
employment with the Company will continue.
