(cid:190) Corporate Profile 

Rexahn  Pharmaceuticals,  Inc.  is  a  clinical  stage  biopharmaceutical  company 

dedicated to the discovery, development, and commercialization of innovative 

treatments 

for  cancers,  central  nervous  system  (CNS)  disorders,  sexual 

dysfunctions and other unmet medical needs. 

Rexahn currently has a number of drug candidates in clinical development for 

cancer,  CNS  disorders  and  sexual  dysfunction.    The  Company’s  lead  cancer 

candidate,  Archexin  (formerly  named  RX-0201)  successfully  completed  Phase  I 

clinical trials in 2006 and begin its Phase II clinical trials in 2007 for patients  with 

advanced stage renal cell carcinoma (RCC), an abnormal growth of cells lining the tubules of the kidney.  In 

the CNS area, Rexahn’s drug candidate for anxiety, Serdaxin (formerly named RX-10100 XR), is expected to 

enter Phase II clinical trials in 2007.  Based on early studies, the compound appears to act on serotonin and 

dopamine, which are key neurotransmitters in the brain implicated in both anxiety and depression.  Similar to 

Serdaxin  for  CNS  disorders,  Zoraxel  (formerly  named  RX-10100  IR)  enhances  both  serotonin  and  dopamine, 

which  coordinate  copulatory  rates  and  sexual  function.      Phase  II  clinical  trials  of  Zoraxel  for  sexual 
dysfunction are planned for 2007.

(cid:190) Pipeline Overview  

Oncology 

According  to  the  American  Cancer  Society’s

Cancer  Facts  &  Figures  2007,  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  1.4

million  new  cases  are  expected 

to  be

diagnosed in 2007. 

Oncology Drug Candidates 

Rexahn’s therapeutic focus in oncology is on signal inhibitors.  Our drug candidates have shown an ability to 

inhibit  the  proliferation  of  cancer  cells,  to  induce  programmed  cell  death  and/or  to  reverse  radiation 

resistance.  

Archexin: AKT-1 inhibitor. Archexin is an antisense ologonucleotide focused on inhibiting the communication 

of  activated  and  native  AKT-1.    AKT-1  is  an  important  target  in  the  treatment  of  cancer.  Specifically,  AKT-1 

plays  a  key  role  in  cancer  progression  by  stimulating  cell  proliferation  and  survival  and  promoting 

angiogenesis.  Archexin inhibits AKT-1 by significantly reducing expressions of its mRNA and protein, resulting in 

disruption  of  signaling  by  both  activated  and  native  AKT-1.    By  contrast,  most  small  molecule  compounds 

only  inhibit  either  activated  or  native  AKT-1.    Phase  I  clinical  trials  for  Archexin  were  completed  in  October 

2006 and the Company expects to begin Phase II clinical trials in the second quarter of 2007 for patients with 

advanced renal cell carcinoma. 

RX-5902: Cell cycle inhibitor. Molecular analysis of human cancer cells has shown that cell cycle molecules 

are frequently mutated in human cancer, suggesting the importance of cell cycle control in the treatment of 

tumors. RX-5902, a piperazine analogue, is a G2/M-specific cell cycle inhibitor as well as a potent inhibitor of 

BCL-2. It also strongly induces apoptosis and inhibits proliferation of many human cancer cells at nano-molar 

concentrations. RX-5902 will soon begin animal toxicity testing and the Company expects to initiate its Phase I 

clinical trials in 2008. 

RX-0047:  HIF-1  Transcription  Factor  Inhibitor.  Preclinical  studies  have  demonstrated  that  RX-0047  is  a  potent 

inhibitor  of  HIF-1,  limiting  the  proliferation  of  various  cancer  cells  at  nano-molar  concentrations,  reversing 

radiation  resistance  and  controlling  the  growth  of  tumors.    Phase  I  clinical  trials  of  RX-0047  are  expected  to 

begin in 2008. 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Neuroscience  

3

Central  nervous  system  (CNS)  disorders,  which  include  generalized 

anxiety  disorder,  panic  disorder,  social  anxiety  disorder,  obsessive-

compulsive  disorder  and  post- 

traumatic  stress  disorder,  affect 

approximately  15%  of  the  U.S.  population  and  are  the  most  common 

form of mental illness.  Depressive disorders, which affect approximately 

9.5%  of  the  U.S.  population,  include  major  depression,  bipolar  disorder 

and dysthymic disorder.  There is significant comorbidity among various 

mental  disorders.    For  example,  nearly  60%  of  patients  with  depression 

also suffer from anxiety. 

Neuroscience Drug Candidates 

The Company’s neuroscience portfolio of compounds may have therapeutic usefulness for the treatment of 

anxiety  and  depression  and  potential  use  for  the  treatment  of  male  sexual  disorders  such  as  erectile 

dysfunction and premature ejaculation. 

Serdaxin. Serdaxin modulates both serotonin and dopamine at the same time with a unique mechanism of 

action that is different from currently marketed anxiolytic and anti-depressant drugs such as benzodiazepines 

and  Selective  Serotonin  Reuptake  Inhibitor  (SSRIs).  In  animal  models  of  hamsters,  mice,  rats  and  monkeys, 

Serdaxin  increased  levels  of  serotonin  and  dopamine  in  the  brain,  exhibited 

potent anxiolytic activities and induced significant active imaging changes in the 

rat  brain  of  functional  magnetic  resonance  imaging  (fMRI).  We  plan  to  initiate 

Phase  II  clinical  trials  of  Serdaxin  in  the  second  half  of  2007,  focusing  on  patients 

with social phobia, clinical category of anxiety.  

Zoraxel. Zoraxel modulates both serotonin and dopamine neurotransmitters, and is 

expected  to  facilitate  sexual  motivation,  copulatory  behavior  and  erectile 

function, and to prevent premature ejaculation by inhibiting seminal emission and 

prolonging ejaculation latency. Phase II clinical studies for sexual dysfunction are 

planned in the second half of 2007.

(cid:190) Letter from the Chairman 

Dear Fellow Stockholders: 

2006 was an important year for Rexahn, during which time we achieved a number of 

milestones,  both  with  respect  to  research  and  development  and  Company 

operations. 

On the product development side, we successfully concluded our Phase I clinical trial 

for our leading oncology candidate, Archexin, formerly known as RX-0201.  Archexin 

directly  blocks  the  production  of  AKT-1,  a  protein  that  plays  a  key  role  in  cancer 

progression.  The  trial,  which  took  place  at  Georgetown  University  and  the  University  of  Alabama,  was  an 

open-label,  dose-escalation  study  intended  primarily  to  determine  the  safety  and  tolerability  of  the 

compound in patients with advanced cancer. Results showed that the drug is safe, with the only dose-limiting 

toxicity  being  fatigue.  Moreover,  patients  on  Archexin  did  not  exhibit  any  major  adverse  reactions,  such  as 

hematological  toxicities.    The  results  were  consistent  with  Rexahn’s  goal  is  to  develop  less  toxic,  more 

targeted therapies. 

Following  the  results  of  the  Phase  I  study,  in  November  2006,  we  secured  a  U.S.  patent  covering  the 

nucleotide  sequences  of  Rexahn’s  drugs  that  target  and  inhibit  the  expression  of  AKT-1  in  human  tissues  or 

cells. The U.S. patent also covers the method of using our compounds to induce cytotoxicity in cancer cells. 

The receipt of this patent, which extends until 2023, was extremely important for the Company, as we seek to 

strengthen  our  intellectual  property  position  and  move  forward  in  the  development  of  Archexin  and  other 

key compounds.  

In addition to the U.S. patent noted above, earlier in the year, Rexahn received a European patent, covering 

a dozen countries, for our lead CNS drug candidate, RX-10100, for the treatment of behavioral diseases.  RX-

10100  is  a  unique  chemical  compound  that,  based  on  studies  to  date,  supports  the  treatment  of  anxiety, 

depression, and other behavioral diseases. This patent was added to the four U.S. patents that the Company 

previously  licensed  exclusivity  for  RX-10100  for  the  treatment  of  anxiety,  depression,  sexual  dysfunction  and 

neuroprotection.  

In our quest to apply cutting-edge nanotechnology to the development and delivery of new drugs, early in 

2006, Rexahn formed collaboration with the University of Maryland's Center for Nanomedicine and Cellular 

Delivery  to  develop  cancer-fighting  drugs  and  CNS  therapies.  Post-doctoral  fellows  are  now  working  at 

Rexahn, under the mentorship of a  University faculty member, to find novel  ways of applying the Center's 

research  and  nanomedicine  expertise  to  improve  the  pharmaceutical  properties  of  Rexahn’s  drug 

candidates.  

 
 
  
  
 
 
 
 
 
5

Drugs  developed  under  this  partnership  have  the  potential  to  provide  a  stable  pipeline  of  additional 

compounds which could offer patients and physicians cancer therapies with better-controlled drug release, 

more  exact  targeting  of  diseased  organs,  and/or  permit  better  access  to  sites  of  action  in  the  brain. 

Successful  drug  development  using  nanomedicine  would  also  help  diversify  Rexahn’s  product  portfolio  by 

prolonging the patent life of an existing drug. We look forward to keeping our shareholders updated on this 

unique program.  

During  the  year,  we  were  pleased  to  welcome  a  number  of  new  Board  members:  Charles  Beever,  partner 

and Vice President of Booz Allen & Hamilton; Kwang Soo Cheong, Associate Professor in the Department of 

Finance at Johns Hopkins University; and Y. Michelle Kang, Vice President and General Manager of Northrop 

Grumman's Information Technology Health Solutions division.  We  would like to extend our gratitude for  their 

contributions thus far and we look forward to utilizing their expertise to help Rexahn.  

The  Monte  Jade  Science  and  Technology  Association  of  Greater  Washington  D.C.  named  us  the  “2006 

Biotechnology  Company  of  the  Year”.    It  was  truly  an  honor  to  be  awarded  by  such  a  respected 

organization.  Going forward, we will continue to work hard to maintain this notable status. 

2007 promises to be equally as active as 2006, with three drug candidates expected to enter Phase II clinical 

trials and a host of other activities planned: we plan to initiate a Phase II clinical trial for Archexin in patients 

with  advanced  renal  cell  carcinoma  during  the  second  quarter  of  2007  and  two  Phase  II  trials  for  anxiety 

(Serdaxin) and premature ejaculation (Zoraxel) in the second half of the year. 

Additionally,  we  are  committed  to  improving  the  Company’s  visibility  within  the  investment  community.  In 

tandem with those efforts, our goal is to apply to move our share listing from the OTC Bulletin Board to one of 

the mainstream stock exchanges.  

 I  am  excited  about  the  future  potential  for  Rexahn  and  the  significant  contributions  that  our  technology 

and  potential  drug  candidates  can  bring  to  the  market.  I  would  like  to  take  this  opportunity  to  thank  our 

employees, Board of Directors, partners and suppliers for their ongoing dedication and commitment to the 

Company. We appreciate your support. 

Thank you very much, 

Dr. Chang H. Ahn,

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 one drug candidate entering Phase II clinical trials 
this year and five other drug candidates in pre-clinical development. We plan to enter two drug candidates 
into  Phase  II  clinical  trials  this  year,  subject  to  obtaining  sufficient  additional  financing.  We  intend  to 
leverage  our  drug-discovery  technologies,  scientific  expertise  and  developmental  know-how  to  develop 
and commercialize signal inhibitor cancer drugs with greater clinical benefits for patients and new drugs 
for  the  treatment  of  diseases  of  the  central  nervous  system.    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. 

Our current therapeutic focus in the anti-cancer area is on therapies that target signal transduction 
molecules of cancer cells.  Signal transduction is the process of transforming external information from 
the cell surface to a specific internal response, such as cell growth or cell death.  Signals are conveyed 
through  tightly  regulated  communication  networks.    The  signaling  pathways  are  comprised  of 
functionally  diverse  molecules,  including  proteins.    Most,  if  not  all,  cancer  disease  states  arise  from 
aberrant  cell  communication.    Recent  trends  in  anti-cancer  chemotherapy  drug  development  involve 
signal  transduction  inhibitors  that  are  target-specific.    Our  signal  transduction  inhibitors  directly  attack 
these signaling pathways and halt the growth of cancer cells.  We believe this approach will lead to the 
development  of  more targeted and less toxic drugs than are  currently available  to help treat cancer and 
that may also have potential applications in other disease areas. 

We  currently  have  a  number  of  drug  candidates  in  clinical  development  for  cancer,  CNS 
disorders  and  sexual  dysfunction.  Our  lead  anti-cancer  drug  candidate,  Archexin,  which  we  previously 
referred to as RX-0201, completed Phase I clinical trials in 2006 and will begin its Phase II clinical trials 
in the second quarter of 2007 in patients with advanced stage renal cell carcinoma (RCC), an abnormal 
growth  of  cells  lining  the  tubules  of  the  kidney.    Additional  Archexin  Phase  II  clinical  trials  in 
gastrointestinal  (GI)  indications,  such  as  pancreatic  and  stomach  cancers,  are  expected  to  follow.  
Archexin received "orphan drug" designation from the Food and Drug Administration, or FDA, for five 
cancer  indications  (RCC,  pancreatic  cancer,  stomach  cancer,  brain  cancer  and  ovarian  cancer).    The 
FDA's 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 
approval  process,  seven  years  of  marketing  exclusivity  after  approval  and  tax  incentives  for  clinical 
research.    We  plan  to  enter  our    RX-10100  drug  candidates  into  Phase  II  trials  for  two  separate 
indications,  anxiety  (as  Serdaxin)  and  sexual  dysfunction  (as  Zoraxel),  in  2007,  subject  to  obtaining 
sufficient  additional  financing  Based  on  early  studies,  both  candidates  appear  to  act  on  serotonin  and 
dopamine, which are key neurotransmitters in the brain implicated in anxiety and sexual dysfunction.

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  efforts  toward 
signal  inhibitor  therapies.    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, diseases of the central nervous system (namely anxiety, depression) 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  to  allow  patients  suffering  from  disease  to  regain 
normalcy in their lives. 

According to the American Cancer Society's Cancer Facts & Figures 2007, cancer is the second leading 
cause of death among Americans and is responsible for one of every four deaths in the United States.  In 2007, 
more than 560,000 Americans are expected to die of cancer and close to 1.4 million new cases are expected to be 
diagnosed.    These  estimates  do  not  include  non-invasive  cancer  or  more  than  1 million  cases  of  basal  and 
squamous cell skin cancers expected to be diagnosed in 2007. 

The  high  rate  of  cancer  prevalence  and  the  inadequacy  of  available  treatments  justify  continued 
investment in new therapies.  In the United States alone, over $25 billion in cancer therapeutics are sold annually.  
According to a market research report by Datamonitor, sales of anti-cancer drugs are predicted to grow each year, 
reaching  $55 billion  globally  in  2009.    The  report  attributes  the  growth  in  sales  to  increased  demand  for 
innovative drugs, which are expected to rise in market share from 18% to 33% of total anti-cancer drug sales by 
2009. 

The National Institute of Mental Health, or NIMH, estimates that 26.2 percent of adults, or 57.7 million 
people,  suffer  from  a  diagnosable  mental  disorder  in  a  given  year.    The  NIMH  also  reports  that  nearly  half  of 
those  with  a  mental  disorder  suffer  from  two  or  more  disorders.    With  this  large  prevalence  and  given  many 
people suffer from more than one mental disorder at a given time, the burden of illness is significant and mental 
disorders are the leading cause of disability in the United States.  The anti-anxiety and anti-depression market is 
estimated to be over $22 billion by 2010 according to a Business Communications article entitled "The Expanding 
Market for Psychotherapeutic Drugs". 

Current Cancer Treatments 

Traditional  cancer  treatments  include  surgery,  radiation  therapy,  and  chemotherapy.    Surgery  is  widely 
used  to  treat  cancer,  and  in  many  cases  cure  cancer,  provided  the  cancer  has  not  metastasized.    However,  the 
complications associated with surgery are significant.  Even if a cure may be achieved through surgery, the costs 
to the patient in terms of health and reduced quality of life often does not support the surgical option. 

2 

 
 
Radiation  therapy,  or  radiotherapy,  is  the  treatment  of  cancer  and  other  diseases  with  ionizing 
radiation and can be highly effective for treating cancers.  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. 

Chemotherapy destroys cancer tumor 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 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 

While surgery remains the best available treatment for long-term survival provided the cancer is 
still localized and radiation and chemotherapy offer more limited benefits for those whose disease is more 
widespread  at  the  time  of  diagnosis,  a  considerable  number  of  unmet  needs  remain  in  the  treatment  of 
cancer. 

•  Long-term  control  of  advanced  tumors:    For  advanced  cancer  (particularly  stage  III-IV 
disease  in  which  the  cancer  has  spread  throughout  the  body),  surgery  cannot  eliminate  the 
tumor and the patient becomes reliant on chemotherapy and/or radiation.  However, current 
chemotherapy, in the majority of cases, fails to eliminate the tumor, tending to, at best, shrink 
the  tumor  and  fails  to  extend  the  patient’s  life.    These  limitations  translate  into  a  need  for 
safer  and  effective  cancer  therapies  offering  a  significant  improvement  in  survival  time  or 
long-term chronic disease control.   

•  Decreased  relapse  for  early-stage  patients:    While  many  early-stage  patients  will  enter 
remission  as  a  result  of  treatment  with  surgery  and  radiation  therapy  and  chemotherapy  as 
well, the rate of relapse is high, as small numbers of tumor cells remain after the treatments 
despite  standard  surgical  and  radiation  therapies.    Upon  relapse,  the  tumor  is  often  more 
aggressive than the initial occurrence, and unresponsive to standard first-line therapies.  The 
development of therapies that can maintain a patient in remission following treatment for the 
initial tumor, rather than permitting relapse, is a significant unmet need. 

•  Less  toxic  therapies:    Current  chemotherapeutic  drugs  are  associated  with  a  high  level  of 
toxicities,  due  to  their  nonspecific  mechanism  of  targeting  all  rapidly  dividing  cells,  rather 
than cancer tumor cells in particular.  For patients with terminal disease, the maintenance of 
quality  of  life,  in  addition  to  extending  life,  is  of  prime  importance;  however,  treatment-
related toxicities severely impair the quality of life of cancer patients.  

Current Renal Cell Carcinoma Treatments 

Renal cell carcinoma (RCC) is one of the most difficult cancers to treat. Current treatments for 
RCC  include  radiation,  surgery  and  chemotherapy.    Only  20%  of  metastatic  RCC  tumors  respond  to 
standard therapy, leaving 80% of advanced RCC patients without any effective treatment. Further, up to 
50%  of  stage  I-III  RCC  patients  relapse  following  treatment.  With  existing  therapies,  the  five-year 
survival rate for RCC patients is less than 20%.  

3 

 
 
  
Given  the  poor  prognosis  of  patients  with  advanced  stage  RCC  disease,  we  believe  the 
development of an effective and less toxic treatment for RCC represents a significant unmet need in the 
marketplace. 

Unmet Needs in RCC Treatment 

Our  first  anti-cancer  drug  candidate  on  the  market  will  focus  on  patients  with  RCC.  Each  year 
nearly  208,000  people  worldwide  are  diagnosed  with  RCC,  the  most  common  form  of  kidney  cancer. 
More than 102,000 die from RCC annually according to the Kidney Cancer Association (2005).  In the 
United States, approximately 30,000 new cases are diagnosed each year, accounting for 3% of all cancer 
cases and approximately 1.5% of all cancer deaths. 

Current CNS Treatments 

Anxiety  is  the  stress  response  (e.g.,  fight,  fright,  flight)  that  is  provoked  by  a  genuine  threat  or 
challenge.    In  a  healthy  individual,  such  stress  is  used  as  a  spur  for  appropriate  action.  However,  in  an 
individual with anxiety, such stress induces an excessive or inappropriate state of arousal characterized by 
feelings  of  apprehension,  uncertainty  and/or  fear,  resulting  in  paralyzing  the  individual  into  action  or 
withdrawal. An anxiety disorder persists once the threat is removed, while a healthy response to a threat 
resolves.  Anxiety  is  linked  to  high  levels  of  amygdale  action  that  are  associated  with  an  increased 
prevalence of anxiety symptoms and dispositional negative affect. 

Anxiety  disorders  are  classified  according  to  the  severity  and  duration  of  their  symptoms  and  specific 
behavioral characteristics. Categories include: 

•  Generalized anxiety disorder (GAD), which is long lasting and low-grade.  
•  Panic disorder, which has more dramatic symptoms.  
•  Phobias.  
•  Obsessive−compulsive disorder (OCD).  
•  Post−traumatic stress disorder (PTSD) 
•  Separation anxiety disorder (which is almost always seen in children). 

Social  phobia,  also  known  as  social  anxiety  disorder,  is  the  fear  of  being  publicly  scrutinized  and 
humiliated and is exhibited by extreme shyness and discomfort in social settings. This phobia often leads 
people to avoid situations and is not due to a physical, mental problem. According to the U.S. National 
Morbidity Survey from 1994, social phobia is the third most common psychiatric disorder in the United 
States.  Prevalence has been estimated at 7%. 

The  anxiety  and  depression  markets  are  dominated  by  a  few  classes  of  products.    Selective 
serotonin  reuptake  inhibitors  (SSRIs) and  serotonin  norepinephrine  reuptake  inhibitors  (SNRIs) are  the 
two major classes of anti-depressants.  SSRIs and benzodiazepines are the most frequently used products 
to treat anxiety.  While many of these products help to control anxiety and depression for some patients, 
they  have  significant  drawbacks  that  limit  patient  use,  such  as  being  potentially  habit-forming,  causing 
drowsiness, limitations on use with certain pre-existing medical conditions, slow onset of action, causing 
sexual  dysfunction,  insomnia  and  interacting  with  certain  food  or  drugs.    The  marketing  exclusivity 
period of many currently marketed drugs for the treatment of anxiety and depression are close to ending, 
resulting  in  fierce  competition  from  generic  drug  makers.    While  major  pharmaceutical  companies  are 
trying to extend the protection of their blockbuster drugs, they also want to develop new classes of drugs 
that  will  give  another  decade  of  exclusivity  with  better  efficacy.    Serdaxin,  as  a  dual  action  drug 
candidate, has a potential to address this market.

Unmet Needs in CNS Therapies 

The  marketing  exclusivity  period  of  many  key  drugs  for  the  treatment  of  anxiety  and  depression  has 
expired  or  is  close  to  expiration  and  has  resulted  in  fierce  competition  from  generic  drug  makers.    Major 
pharmaceutical companies are waiting for better and safer new classes of drugs that will give them another decade 
of exclusivity in the market. 

•  Better safety profile:  Adverse reactions associated with current SSRI anxiolytics and antidepressants 
include nausea, sexual dysfunction, insomnia, suicidal tendency and weight gain.  The occurrence of 
one  or  more  of  these  side  effects  in  patients  is  the  primary  reason  that  over  30%  of  patients 
discontinue use of these treatments. 

•  Fast therapeutic onset with immediate results:   Onset of therapeutic action within the first week of 
use has been one of the key goals for all drug discovery programs involved in treating anxiety and 
depression.  All current medications require several weeks to see therapeutic onset.   

•  Broad  spectrum  of  activity:    The  vast  majority  of  patients  who  suffer  from  anxiety  also  display 
symptoms  of  depression  and  vice  versa.    In  the  past,  each  disorder  was  treated  with  separate 
medications.  Recent clinical studies have demonstrated the ability of SSRIs to be somewhat effective 
in treating both anxiety and depression.  Newer drugs should have more potent efficacy with better 
safety profiles than SSRIs to address both symptoms of anxiety and depression. 

Current Sexual Dysfunction Treatment   

There are currently only three oral drugs approved on the market to treat erectile dysfunction.  All three 
products  are  selective  inhibitors  of  phosphodiesterase  type  5  (PDE5).    These  drugs  may  result  in  numerous 
adverse reactions, including cardiovascular effects and death.  Zoraxel is not a PDE5 inhibitor, but works through 
a brain mediated mechanism that produces release of serotonin and dopamine.  There are currently no products on 
the market to treat premature ejaculation, although a few products are in development.   

Unmet Needs in Sexual Dysfunction   

Premature ejaculation represents the largest segment of male sexual dysfunction. An estimated 30 million 
men  in  the  United  States  and  36 million  in  Europe  suffer  from  premature  ejaculation,  however,  there  are  few 
treatment options available. There is presently no approved drug for treatment of premature ejaculation. 

Market Opportunity 

We  believe  that  several  factors  make  drug  development  for  cancer  and  diseases  of  the  central  nervous 

system attractive to large pharmaceutical companies, including: 

•  Favorable Environment for Formulary Access and Reimbursement.  Given the significant death rate, 
the relatively poor performance of existing drugs, and the life threatening nature of cancer, decisions 
by  medical  providers  and  health  insurance  companies  are  more  heavily  focused  on  outcomes  than 
product cost for cancer drugs compared to drugs from other therapeutic classes.  As a result cancer 
drugs  with  proven  efficacy  are  expected  to gain  rapid  formulary  listing  and  patient  reimbursement, 
and  in  addition,  drugs  that  have  orphan  designations  are  generally  reimbursed  by  insurance 
companies given that there are few, if any, alternatives.  Since mental disorders affect an estimated 
57.7 million people in the United States, 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. 

5 

 
 
 
 
 
•  Focus on Specialty Markets.  Cancer patients are treated by oncologists, a group of physician 
specialists  who  are  early  adopters  of  new  therapies.    Marketing  products  to  this  physician 
group can be accomplished with a specialty sales force that requires less investment than a 
typical product sales force that markets to primary care physicians and general practitioners.   

•  Lower  Development  Expenses/Shorter  Development  Time.    Drugs  for  life-threatening 
diseases  such  as  cancer  are  often  treated  by  the  Food  and  Drug  Administration  (FDA) as 
candidates for fast track, priority and accelerated reviews.  Clinical studies for cancer require 
fewer patients than those for non-life threatening diseases.  This results in reduced cost and 
shorter  clinical  trials.    Our  lead  CNS  product,  Serdaxin,  is  also  expected  to  have  lower 
development  expenses  as  well  as  shorter  development  time  given  the  drug  has  been  on  the 
market for 20 years for other treatments, with a well-established safety record. 

Our  therapeutic  areas  focus  on  large  markets  with  significant  unmet  needs.    The  high  rate  of 
cancer  prevalence  and  the  inadequacy  of  available  treatments  justify  continued  investment  in  new 
therapies.  Datamonitor estimates that in 2004, drugs for the treatment of cancer represented a $40 billion 
market.    In  the  United  States  alone,  over  $25 billion  in  cancer  therapeutics  are  sold  annually.    Sales  of 
cancer drugs are predicted to grow annually reaching $55 billion globally in 2009.  Datamonitor attributes 
the  sales  growth  will  be  driven  mainly  by  innovative  drugs,  increasing  the  market  share  of  innovative 
cancer therapy from 18% presently to 33% of total cancer sales by 2009. 

Our Strategy 

Our goal is to build value through a strong drug pipeline and marketed products in each of our 
market segments (cancer,  CNS and sexual dysfunction)  or sub-segments; however, to date, we have no 
marketed products.  To achieve these goals, our strategy has several key components: 

Target Signal Transducer 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  will  seek  to  establish  partnerships  with  large  pharmaceutical  companies  in  order  to  reduce 
drug development costs and to expand the disease treatment indications of the drug candidates and access 
to  markets.    We  plan  to  market  products  for  which  we  obtain  regulatory  approval  either  directly  or 
through  co-marketing  arrangements  or  other  licensing  arrangements  with  large  pharmaceutical 
companies.    To  market  those  drug  candidates  with  disease  treatment  indications  that  are  larger  or 
geographically  diverse,  we  expect  to  enter  into  licensing,  distribution  or  partnering  agreements  with 
pharmaceutical companies that have large established sales organizations; however, to date, we have not 
entered into such agreements with any large pharmaceutical companies. 

6 

 
 
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 
for  these  potential  products.    Our  drug  candidates  may  also  be  effective  against  non-orphan  category 
cancers,  providing  additional  market  opportunities  for  off-label  use.    This  would  enable  us  to  either 
license these drugs for further development by major pharmaceutical companies or conduct the necessary 
studies to seek FDA approval for additional disease treatment indications.  In the future, we may develop 
drug  candidates  for  other  orphan  category  diseases  to  take  advantage  of  our  expertise  with  the  orphan 
drug development process.   

In-License Unique Technology  

We  seek  to  keep  abreast  of  emerging  technologies  and  development  stage  drugs.    We  seek  to 
proactively review opportunities to in-license 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.  
For  example,  in  February 2005,  we  licensed  the  intellectual  property  of  Revaax  Pharmaceuticals  LLC 
("Revaax")  for  development  as  potential  drug  candidates  for  the  treatment  of  neurological  diseases.  
Through licensing arrangements, we seek to strengthen our pipeline of drug candidates.   

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.    We  believe  that  this  knowledge  and 
experience with the FDA drug approval process permits us to develop strategies that take advantage of 
the FDA's fast track policies.  Where possible, our management will seek to use their experience to design 
and implement drug development programs that minimize the time for clinical trials, while maximizing 
success  rates  for  approval  of  our  drug  candidates.    Members  of  our  management  team  also  have  prior 
experience in pharmaceutical product launch and marketing. 

Our Pipeline Drug Candidates 

Our  anti-cancer  therapeutic  technology  consists  of  both  proprietary  RNA/DNA-based  signal 
transduction  inhibitors  and  small  molecule  candidate  compounds  believed  to  be  effective  for  treating  a 
large  number  of  human  cancers.    We  have  a  number  of  drug  candidates  in  clinical  development  for 
cancer, CNS disorders and sexual dysfunction. In 2006, Phase I clinical trials of Archexin in patients with 
advanced cancer was successfully completed. In 2007, we plan to initiate Phase II clinical trials targeting 
patients with renal cell cancer (Archexin), and plan to initiate, subject to obtaining sufficient additional 
financing, Phase II clinical trials targeting patients with social phobia (Serdaxin) and sexual dysfunction 
(Zoraxel).  The following description of our pipeline drug candidates is based on clinical and pre-clinical 
trials and studies. 

7 

 
 
Cancer 

Our  unique  approach  to  improving  cancer  patients’  lives  is  to  develop  potent,  targeted 

therapeutics with fewer side effects than current chemotherapeutics, which are highly toxic.   

We  develop  targeted  therapeutics  that  directly  disrupt  the  signals  responsible  for  the  disease 
progression. Through a process known as signal transduction, external information is transmitted from the 
cell surface to specific internal signal molecules for specific functional responses, such as cell growth or 
cell death.  The signaling pathways are comprised of functionally diverse molecules, including proteins.  
Most, if not all, cancer disease states arise from aberrant cell communication. Our drug candidates target 
critical  signal  molecules  in  cell  signaling  pathways,  which  are  believed  to  have  a  broad  and  highly 
effective impact on cell survival, proliferation, metastasis and angiogenesis.  

Our  signal  targets  (e.g.  Akt  and  HIF-1)  are  over-expressed  and/or  over-activated  in  many 

different types of human solid tumors, giving our anticancer drugs utility across a wide range of cancers. 

Archexin:  First-in-class Akt Inhibitor 

Our  leading  anti-cancer  drug  candidate,  Archexin,  inhibits  cellular  communication  of  both 
activated and native Akt.  Akt is an important target in the treatment of cancer because it plays a key role 
in  cancer  progression  by  stimulating  cell  proliferation  and  cell  survival,  and  promoting  angiogenesis. 
Archexin  inhibits  Akt  by  significantly  reducing  expressions  of  its  mRNA  and  subsequently  its  protein, 
resulting in disruption of signaling by both activated and native Akt. Small molecule compounds may 
only be able to inhibit either activated or native protein.  

In  October 2006,  we  announced  the  conclusion  of  the  Phase  I  clinical  trial  of  Archexin.    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.    The  Phase  I  study  demonstrated  that  fatigue  was  the  dose  limiting  toxicity.  Unlike  most  anti-
cancer drugs, no hematological abnormalities were observed.    The Phase II trial, which is expected to 
last 1 ½ to 2 years, is expected to begin in the second quarter of 2007 and will be a multi-center study in 
the U.S. and worldwide. To enhance cellular uptake and improve tumor targeting, we are also developing 
a nanotechnology-based delivery system for Archexin.  With an outstanding profile of safety established, 
the  goal  of  Phase  II  is  to  determine  the  efficacy  of  Archexin  in  patients  with  late  stage  renal  cell 
carcinoma, one of the orphan indications for which we received orphan drug designation from the FDA. 
In addition, we plan to expand Archexin to the treatment of other orphan and non-orphan indications. 

In  November 2006,  we  announced  that  we  had  been  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. 

8 

 
 
 
RX-5902: Microtubule Inhibitor and RX-0047:  First-in-class HIF-1 Alpha Inhibitor  

Our RX-5902 and RX-0047 drug candidates are both 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.    RX-5902,  a  piperazine  analogue,  is  a  microtubule 
inhibitor specifically acting on G2/M cell cycle.  In pre-clinical studies, it strongly induced apoptosis and inhibited 
proliferation of various human cancer cells at nanomolar concentrations, and significantly reduced the growth of 
tumors  in  animal  xenograft  models.    RX-5902  demonstrated  potent  anti-proliferating  effects  on  drug-resistant 
cancer cells and showed synergism with known anti-cancer drugs as well.  RX-5902 appears to process excellent 
oral bioavailability and thus may be developed in both intravenous and oral forms.  RX-5902 is expected to enter 
Phase I clinical trials in 2008.  RX-0047 directly inhibits HIF-1 by reducing expressions of its mRNA and protein. 
HIF-1  is  a  major  regulating  mechanism  of  cancer  cell  growth,  invasion,  angiogenesis  and  radiation  resistance.  
HIF is known to be over-expressed in a broad range of human cancers and is associated with increased mortality, 
metastasis and/or resistance to radiation therapy. 

Preclinical  studies  demonstrated  that  RX-0047  inhibits  proliferation  of  various  human  cancer  cells  at 
nanomolar  concentrations  and  significantly  reduced  tumor  growth  and  metastasis  in  animal  xenograft  models.  
Phase I clinical trials of RX-0047 are expected to begin in 2008. 

CNS 

CNS disorders are another one of our therapeutic focus areas.  We have exclusive patent rights (five U.S. 
patents  and  multiple  pending  patents)  on  a  series  of  compounds  that  affect  anxiety,  depression,  cognition, 
aggression and neurodegenerative diseases. 

Serdaxin,  Rexahn’s 

leading  CNS  drug  candidate,  modulates  both  serotonin  and  dopamine 
neurotransmitters, simultaneously, making it a potent therapy for anxiety and depression.  The active ingredient of 
Serdaxin  has  been  in  medical  use  in  other  treatments  for  more  than  two  decades  and  its  safety  has  been  well 
established.  

Serdaxin 

Serdaxin  acts  on  the  neurotransmission  systems  of  serotonin  and  dopamine,  which  are  key  controlling 

mechanisms of anxiety and mood disorders. 

It  has  been  recognized  that  Serotonin  is  linked  to  the  negative  affect  mood  factor  leading  to  negative 
mood states such as anxiety, disgust, fear, guilt, hostility, irritability and loneliness. Recent findings indicate that 
dopamine is linked to the positive affect related to positive mood states such as happiness, pleasure, motivation, 
and  energy  mood  factor.  Symptoms  of  mood  disorders  are  causally  related  and  clinical  evidence  identifies  low 
levels of dopamine in the brain of patients. The negative mood states as well as loss of the positive mood states 
are common to both anxiety and mood disorders. 

Serdaxin modulates both serotonin and dopamine at the same time with unique mechanisms of action that 
is different from currently marketed anxiolytic and anti-depressant drugs such as benzodiazepines and SSRIs. In 
animal models of hamsters, mice, rats and monkeys, Serdaxin increased levels of serotonin and dopamine in the 
brain,  exhibited  potent  anxiolytic  activities,  and  induced  significant  active  imaging  changes  in  the  rat  brain  in 
fMRI(functional  magnetic  resonance  imaging)  tests.  However,  Serdaxin  did  not  disrupt  learning  and  memory 
functions unlike current anxiolytic drugs.  

We plan to initiate, subject to obtaining sufficient additional financing, Phase II clinical trials of Serdaxin, 

beginning in the second half of 2007, focusing on patients with social phobia, a category of anxiety. 

9 

 
 
 
 
Sexual Dysfunction 

We also aim to develop therapeutics for sexual dysfunction indications.  

Zoraxel  

Similar to Serdaxin for CNS disorders, Zoraxel, our leading sexual dysfunction drug candidate, modulates 
both serotonin and dopamine neurotransmitters, which coordinate copulatory rate and sexual function. The active 
ingredient of Zoraxel has been in medical use in other treatments for more than two decades and its safety has 
been well established.   

As coordinated changes in serotonin and dopamine release in different areas of the brain appears to play a critical 
role in controlling sexual dysfunction, Zoraxel will also be evaluated in the treatment of patients with sexual dysfunction 
(erectile  dysfunction  and  premature  ejaculation)  more  safely  and  effectively  by  enhancing  dual  neurotransmitters 
simultaneously. In rodent and monkey models of sexual dysfunction, Zoraxel was shown to significantly enhance sexual 
activities. 

We plan to initiate, subject to obtaining sufficient additional financing, Phase II clinical trials of Zoraxel 

for sexual dysfunctions beginning in the second half of  2007. 

Competition 

Our  principal  drug  candidates  under  development  are  expected  to  address  unmet  medical  needs  within  the 
oncology, CNS and sexual dysfunction markets.  For many of these disease treatment indications, our drug candidates will 
be competing with products and therapies either currently existing or expected to be developed.  Competition among these 
products  will  be  based,  among  other  things,  on  product  efficacy,  safety,  and  reliability,  price  and  patent  position.    An 
important factor will be the timing of market introduction of our competitive products.  Accordingly, the relative speed with 
which  we  can  bring  drug  candidates  to  the  market  is  expected  to  be  an  important  competitive  factor.    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  both  privately  and  publicly  held  that  are 
conducting research and development activities on technologies and products for treatment of cancers, CNS diseases and 
sexual  dysfunction.    We  cannot  assure  you  that  our  competitors  will  not  succeed  in  developing  products  based  on 
technology which is similar to ours, or other novel technologies that are more effective than any which are being developed 
by  us  or  which  would  render  our  technology  and  products  obsolete  and  noncompetitive  prior  to  recovery  by  us  of  the 
research, development and commercialization expenses incurred with respect to those products.   

Our  competitors  engaged  in  developing  treatments  for  cancer,  CNS  and  sexual  dysfunction  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.  Accordingly, 
our competitors may succeed in obtaining FDA approval for products more rapidly than we can.   

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 
activities on technologies and products for treatment of those other diseases, increasing both the number and the types of 
competitors we face.  For many of the same reasons described above with respect to our competitors in the cancer, CNS and 
sexual dysfunction market, we cannot assure you that we will compete successfully against these additional competitors.

Competition for Archexin 

Direct  competitors  for  Archexin  are  anti-cancer  therapies  that  treat  RCC.  Current  noninvasive 
treatments for RCC include immunotherapy and chemotherapy.  Immunotherapy manipulates the immune 
system  to  improve  the  body's  natural  defense  against  cancers,  using  cytokines  such  as  interferon-alpha.  
However,  cytokine  therapy  has  several  shortcomings,  such  as  high  cost  and  severe  toxicities. 
Chemotherapy usually targets cells that divide quickly, including normal cells such as those found in the 
blood,  hair,  and  the  lining  of  the  gastrointestinal  tract.    Chemotherapy  can  damage  these  healthy  cells 
leading to serious side effects such as nausea, anemia, hair loss, fatigue, nerve pain, infection and even 
treatment-related cancers.  

Nexavar, developed by Bayer/Onyx, and Sutent, developed by Pfizer, are the most recently FDA-
approved  drugs  to  treat  metastatic  RCC.    These  drugs  showed  only  limited  extension  of  PFS 
(Progression-Free Survival) in patients with no prior cytokine therapy. Both have side effects such as skin 
rash, diarrhea, and hypertension.   

We believe that the efficacy and safety profile of Archexin will make it an excellent alternative to 
existing therapies for RCC and other cancer indications. With fatigue as Archexin ’s only dose limiting 
toxicity, we believe that Archexin can be an important addition to current treatments. 

Competition for Serdaxin 

SSRIs and anxiolytics are most frequently used to treat anxiety.  While many of these products 
help  to  control  anxiety,    they  have  significant  drawbacks  that  limit  patient  compliance,  such  as  being 
potentially  habit-forming,  causing  drowsiness,  motor  impairment,  slow  onset  of  action,  sexual 
dysfunction, insomnia, weight gain, and suicidal tendencies.   

Major competitors of Serdaxin are SSRIs currently on the market (e.g., Zoloft, Prozac and Paxil). 

Certain SSRIs are approved to treat depression, anxiety, and/or premenstrual dysphonic disorder (PMDD).  
The most common side effects of SSRIs include dry mouth, insomnia, sexual side effects (e.g., decreased 
libido, delayed ejaculation), diarrhea, nausea, and sleepiness. 

Despite  their  shortcomings,  anxyliotics  and  SSRIs  are  expected  to  continue  to  dominate  the 
market  for  anxiety  therapy.    However,  we  believe  that  Serdaxin  may  be  a  superior  treatment  for  the 
following reasons: 

•  Safety:  Serdaxin has established an excellent safety profile, and appears to avoid the major side 

effects associated with  SSRIs and anxyliotics. 

•  Potency:    Combined  effects  of  the  serotonin  and  dopamine  appear  to  be  pharmacologically 
superior to SSRIs and anxyliotics, potentially covering patients from both negative mood states 
and loss of positive mood states. 

•  Patent:    Unlike  the  most  SSRIs  whose  patents  have  expired  or  will  soon  expire,  Serdaxin  ’s 

patent extends until 2024 or longer. 

11 

 
 
 
Competition for Zoraxel 

There  is  currently  no  approved  drug  for  treating  premature  ejaculation,  though  many  are  under 
development.  Two leading candidates in various stages of development are Dapoxetine, developed by ALZA and 
Johnson & Johnson, and PSD502, developed by Plethora Solutions. 

Dapoxetine  has  been  demonstrated  to  be  relatively  effective  in  treating  premature  ejaculation  when 
administered from 30 minutes to 4 hours before sexual activity.   However, the sponsor of the drug had withdrawn 
its NDA application, in part due to potential tumor formation. 

PSD502  is  a  topical  mixture  for  treatment  of  premature  ejaculation.    Side  effects  observed  in  Phase  II 
clinical trials include hypoesthesia, a partial loss of sensitivity to sensory stimuli.  PSD502 is currently in Phase 
III of development by Plethora Solutions. 

Despite  several  drugs  under  development  (e.g.,  SSRIs  with  short  half-lives,  such  as  Dapoxetine))  we 
believe  Zoraxel  will  provide  superior  benefits  to  the  potential  competitors  for  patients  with  sexual  dysfunction 
with its excellent safety profile and CNS-based dual neurotransmitter mechanisms that control sexual activities. 

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 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. 

12 

 
 
In  Phase III,  the  drug  is  administered  to  a  larger  group  of  patients  (usually  1000  to  3000)  by 
practicing  expert  physicians  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.  Phase III is 
intended to model more closely the real world in which the drug will be used.  Two multiclinical trials 
typically constitute Phase III evaluations.  Although larger numbers of patients are evaluated in Phase III 
at more clinical study sites, many of these are done in parallel and therefore Phase III may not require a 
longer time than Phase II. 

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 
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  the  use  of  a  product  as  a  treatment  in  clinical  disease 
treatment  indications  other  than  those  for  which  the  product  was  initially  tested.    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".    Each  designation  request  must  stand  on  its  own  merit.  
Sponsors  requesting  designation  of  the  same  drug  for  the  same  disease  treatment  indication  as  a 
previously  designated  product  must  submit  their  own  data  in  support  of  their  designation  request.    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.    As  a 
result,  orphan  drug  designation  blocks  all  other  competitors  from  marketing  the  same  drug  for  the 
approved use for seven years. 

13 

 
 
Sales and Marketing 

We seek to market our products as a market leader or first-in-class drug in each of its therapeutic 
categories  or  subcategories.    We  will  have  two  distinct  marketing  channels,  depending  on  the  relative 
market size and required resources.  For orphan indication drugs targeting specialized physicians, we plan 
to  maintain  our  own  marketing  campaign  by  building  a  specialty  sales  force.    In  cancer  treatment,  the 
oncologist  is  virtually  the  sole  decision  maker,  with  certain  limitations  by  health  insurance  companies.  
The specialty sales representatives will regularly visit oncologists, especially those who have experience 
of treating orphan cancer such as RCC.   

We  will  form  a  co-marketing  partnership  with  a  large  pharmaceutical  company  to  market  non-
orphan indication drugs like Serdaxin and Zoraxel for CNS diseases and sexual dysfunction, which has a 
much larger market segment.  The number of potential patients and clinicians who treat such patients are 
many. The partner’s sales reps will cover broader stakeholders which will include physicians, patients and 
insurance  companies.  We  believe  that  a  large  pharmaceutical  partner  is  best  equipped  to  manage  and 
execute the most effective means of reaching the consumers and of differentiating our product from those 
already on the market. 

Research and Development  

Our  research  and  development  has  focused  on  proprietary  multi-targeting  genomics  and 
nanotechnology-based  projects.  Our  genomics-based  platform  technology  is  aimed  at  novel  targets  to 
affect  multiple  signaling  events  in  cancer  cell  proliferation  and  growth.    We  are  also  exploring 
nanomedicine-based approaches to develop a targeted drug delivery system to improve the efficacy and 
safety  of  its  therapeutics.    For  a  discussion  of  collaboration  arrangements  pursuant  to  which  we  obtain 
research  and  development  services  from  universities,  research  institutions  and  other  organizations,  see 
"Collaboration  Agreements"  and  "Certain  Relationships  and  Related  Transactions"  in  Item 12  of  this 
Annual Report. 

Multi-Targeting Genomics Platform 

Cancer is a complex disease caused by multiple factors including multiple genetic changes.  Due 
to  the  multiplicity  of  its  causal  mechanisms,  cancer  treatment  involves  a  combination  of  drugs  with 
different  mechanisms  of  action.    The  resulting  outcome  is  a  severe  compounded  accumulation  of 
toxicities  from  each  drug.    Our  approach  is  to  control  multiple  mechanisms  of  cancer  cell  proliferation 
and growth with a single agent, instead of a combination therapy, so that only toxicities, if there are any, 
from  the  single  agent  may  be  expressed.    We  have  conducted  numerous  genomics-based  studies  and 
established  an  integrated  system,  named  CAMTAS,  which  enabled  us  to  discover  potentially  important 
targets that control multiple genes.  We believe that this novel approach will lead to the discovery of new 
cancer drugs based on newly discovered targets, offering greater clinical benefits for cancer patients.   

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.    Currently,  nanoliposome-  and  nanopolymer-based  anti-cancer  drugs  are  under  development.  
To  accelerate  its  efforts,  we  are  collaborating  with  the  Center  for  Nanomedicine  of  the  University  of 
Maryland.  Recently, the Maryland Industrial Partnerships (MIPS) program awarded us with a two-year 
grant to develop nanomedicine-based anti-cancer drugs.

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.

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.    Our 
policy  is  to  file  patent  applications  to  protect  technology,  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.  As of March 2007, we have one U.S. patent issued, one allowed and three patent applications 
pending in cancer treatment.  In March 2005, we licensed-in CNS-related intellectual property (five U.S. 
patents, five pending patents and multiple worldwide coverage) 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.    See 
"Collaboration  Arrangements"  and  "Certain  Relationships  and  Related  Transactions"  in  Item 12  of  this 
Annual Report on Form 10-KSB for a description of the intellectual property rights we have or share in 
connection  with  our  collaborative  research  and  development  relationships  with  universities,  research 
institutions and other organizations. 

Collaboration and License Arrangements 

We  have  numerous  collaborative  research  and  development  relationships  with  universities, 
research  institutions  and  other  organizations.    Also  see  the  discussion  in  "Certain  Relationships  and

therapeutics.    Intellectual  property  made  or  developed  under  this 
agreement is jointly owned by us and UMD. 

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 
disorders.  This agreement expires upon the expiration of the royalty 
term for all licensed products in all countries, which is no earlier than

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 year 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  year,  including  the  clinical  trials  of  Archexin.    We  plan  to  initiate,  subject  to  obtaining 
sufficient  additional  financing,  Phase  II  clinical  trials  of  Serdaxin  and  Zoraxel  beginning  in  the  second 
half of 2007 at an additional cost of up to approximately $3 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 $7 million through the end of 2007. 

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,  2006  and  2005  was  $20,690,326  and  $14,204,323,  respectively.    For  the  years  ended 
December 31, 2006 and 2005, we had net losses of $6,486,003 and $6,349,540, 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:  

• 

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

17 

 
 
• 

• 

• 

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  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. 

18 

 
 
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, both Archexin and RX-0047 are of a drug class (Akt inhibitor, in the case of Archexin, and 
HIF inhibitor, in the case of RX-0047) that has not been approved by the FDA to date.  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,  we  expect  Archexin,  an 
oncology  drug  candidate,  to  enter  Phase  II  clinical  trials.  We  plan  to  initiate,  subject  to  obtaining 
sufficient additional financing, Phase II clinical trials of Serdaxin and Zoraxel, neuroscience and sexual 
dysfunction drug candidates, beginning in the second half of 2007. 

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; 

19 

 
 
• 

• 

• 

• 

• 

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.    

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. 

20 

 
 
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 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. 

21 

 
 
•  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. 

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, academic institutions, government agencies and 
other public and private research organizations, such as Keryx Biopharmaceuticals,  Genta Incorporated 
and Imclone Systems Incorporated. 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; 

22 

 
 
• 

• 

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. 

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, 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. 

23 

 
 
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: 

•  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. 

24 

 
 
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.   

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,  2006  and  2005  was  $20,690,326  and 
$14,204,323,  respectively.    For  the  years  ended  December 31,  2006  and  2005,  we  had  net  losses  of 
$6,486,003  and  $6,349,540,  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 

25 

 
 
•  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 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, a person who has held restricted shares for a period of one year 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  500,000  shares)  during  a  three-month  period.    Any  of  the  restricted 
shares may be freely sold by a non-affiliate after they have been held two years. 

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 500 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 in Rockville, Maryland.  
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 3.  Legal Proceedings. 

We are not subject to any pending legal proceedings, nor are we aware of any threatened claim 

against us. 

Item 4.  Submission of Matters to a Vote of Security Holders. 

None.

PART II 

Item 5.  Market for Common Equity and Related Stockholder Matters. 

As of March 30, 2007, we are authorized to issue two classes of capital stock, which are common 
stock  and  preferred  stock.    Our  total  authorized  shares  of  common  stock  and  preferred  stock  are 
500,000,000  shares,  par  value  $0.0001 per  share,  and  100,000,000  shares,  par  value  $0.0001, 
respectively.    As  of  March 30,  2007,  we  have  50,308,132  shares  of  common  stock  outstanding  and 
approximately  500 stockholders  of  record  of  common  stock.    As  of  March 30,  2007,  no  shares  of 
preferred stock are outstanding.

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 
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. 

29 

 
 
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 

In  December 2004,  the  Financial  Accounting  Standards  Board  ("FASB")  issued  Statement  of 
Financial Accounting Standards ("SFAS") No. 123 (Revised 2004), "Shared-Based Payment" ("SFAS No. 
123R").  This pronouncement amends SFAS No. 123, "Accounting for Stock-Based Compensation" and 
supersedes  Accounting  Principles  Board  ("APB") Opinion  No.  25,  "Accounting  for  Stock  Issued  to 
Employees".  SFAS No. 123R requires that companies account for awards of equity instruments issued to 
employees  under  the  fair  value  method  of  accounting  and  recognize  such  amount  in  the  statement  of 
operations.  The implementation of this statement was effective January 1, 2006 and has been adopted by 
the Company using the modified prospective method. 

For  all  non-employee  stock-based  compensation  the  Company  uses  the  fair  value  method  in 

accordance with SFAS No. 123 and EITF 96-18. 

In management's opinion, existing stock option valuation models do not provide a reliable single 
measure of the fair value of employee stock options that have vesting provisions and are not transferable.  
As option valuation models require the input of highly subjective assumptions, changes in such subjective 
assumptions can materially affect the fair value estimate of employee stock options. 

Prior to the adoption of SFAS No. 123R, the Company used the intrinsic value method to account 
for  stock-based  compensation  in  accordance  with  APB  Opinion  No.  25  and,  as  permitted  by  SFAS 
No. 123,  provided  pro  forma  disclosures  of  net  loss  and  loss  per  common  share  as  if  the  fair  value 
methods  had  been  applied  in  measuring  compensation  expense.    Under  the  intrinsic  value  method, 
compensation cost for employee stock awards is recognized as the excess, if any, of the deemed fair value 
for financial reporting purposes of our common stock on the date of grant over the amount an employee 
must  pay  to  acquire  the  stock.    Compensation  cost  is  amortized  over  the  vesting  period  using  an 
accelerated  graded  method  in  accordance  with  FASB  Interpretation  No.  28,  "Accounting  for  Stock 
Appreciation Rights and Other Variable Stock Option or Award Plans". 

30 

 
 
Our results include non-cash compensation expense as a result of stock option grants.  For stock-
based  awards  prior  to  January 1,  2006,  we  accounted  for  stock-based  employee  compensation 
arrangements in accordance with the provisions of APB Opinion No. 25, "Accounting for Stock Issued to 
Employees" and comply with the disclosure provisions of SFAS No. 123, "Accounting for Stock-Based 
Compensation" ("SFAS No. 123").  Compensation expense for options granted to employees represents 
the difference between the fair market value of our common stock and the exercise price of the options at 
the  date  of  grant.    This  amount  is  being  recorded  over  the  respective  vesting  periods  of  the  individual 
stock options.  We expect to record additional non-cash compensation expense in the future, which may 
be significant.  Compensation for options granted to non-employees has been determined in accordance 
with SFAS No. 123 and EITF 96-18, "Accounting for Equity Instruments that are Issued to Other Than 
Employees  for  Acquiring,  or  in  Conjunction  with  Selling,  Goods  or  Services,"  as  the  fair  value  of  the 
equity instruments issued. 

On  August 5,  2003,  the  Company  established  a  stock  option  plan.    Under  the  plan,  we  issued 
options  to  employees  and  non-employees  during  fiscal  2004  and  incurred  a  compensation  expense  of 
$230,770.    During  fiscal  2005,  we  incurred  a  compensation  expense  of  $436,748  for  options  issued  to 
employees and non-employees.   

The plan grants stock options to key employees, directors and consultants of the Company.  For 
grants prior to September 12, 2005 and grants to  employees of the Company after September 12, 2005, 
the vesting period is 30% after the first year, an additional 30% after the second year and the remaining 
40%  after  the  third  year.    For  grants  to  non-employee  directors  and  consultants  of  the  Company  after 
September 12, 2005, the vesting period is 100% after the first year, 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, subject to the fulfillment of certain conditions 
in the individual stock option grant agreements. 

The exercise prices of the options granted to employees were below the fair market value of the 
common stock on the date of the grant.  In December 2005, employees holding stock options that were 
not  vested  as  of  December 31,  2004  and  stock  options  that  were  granted  on  or  after  January 1,  2005 
agreed  to  amend  the  exercise  prices  of  those  options  from  $0.24 per  share  to  $0.80 per  share,  the  fair 
market value of the common stock (as determined by the board of directors), in order to comply with the 
requirements of Internal Revenue Code Section 409A.  The repricing of the options issued to employees 
was accounted as a cancellation of existing options and issuance of new options.  The effective date of 
this  repricing  was  January 1,  2005.    The  amendment  was  accounted  for  prospectively  and  resulted  in  a 
reversal of stock option compensation expense of $306,896 related to employee options recorded in the 
period from January 1, 2005 to September 30, 2005.  There was no impact on the Company's results of 
operations  for  the  year  ended  December 31,  2004.    Using  the  intrinsic  value  method,  the  total 
compensation cost for the year ended December 31, 2005 amounted to $0 (2004-$658,000) and is being 
amortized over the vesting period. 

The  options  issued  to  certain  non-employees  accounted  under  the  fair  value  method  were 
similarly repriced as of January 1, 2005.  As a result, Stock Compensation expense of $158,531 recorded 
in the period from January 1, 2005 to September 30, 2005, related to non-employee options was reversed.  
The stock compensation expense related to non-employees during 2005 was $436,748, after accounting 
for the repricing adjustment.

stock option compensation expense. 

Recently Issued Accounting Standards 

In  July 2006,  the  FASB  issued  Financial  Accounting  Standards  Interpretation  No.  48  ("FIN  48"), 
"Accounting for Uncertainty in Income Taxes".  FIN 48 clarifies the accounting for uncertainty in income 
taxes  recognized  in  an  enterprises'  financial  statement  in  accordance  with  SFAS  No.  109, "Accounting for 
Income  Taxes".    FIN  48  prescribes  a  recognition  threshold  and  measurement  attributable  for  the  financial 
statement recognition and measurement of a tax position taken or expected to be taken in a tax return.  FIN 
48  also  provides  guidance  on  derecognition,  classification,  interest  and  penalties,  accounting  in  interim 
periods, disclosures and transitions.  FIN 48 is effective for fiscal years beginning after December 15, 2006.  
The Company is currently reviewing the effect, if any, FIN 48 will have on its financial position and results 
of operations 

In September 2006, the Securities and Exchange Commission ("SEC") staff issued Staff Accounting 
Bulletin  ("SAB") No.  108,  "Considering  the  Effects  of  Prior  Year  Misstatements  when  Quantifying 
Misstatements  in  Current Year  Financial  Statements".    SAB  No. 108  was  issued  to provide  consistency in 
how  registrants  quantify  financial  statement  misstatements.    The  Company  is  required  to  and  has  applied 
SAB  No.  108  in  connection  with  the  preparation  of  is  annual  financial  statements  for  the  year  ending 
December 31,  2006.    The  application  of  SAB  No.  108  did  not  to  have  a  material  effect  on  its  financial 
position and results of operations. 

On September 15, 2006, the FASB issued SFAS No. 157, "Fair Value Measurements".  SFAS No. 
157 provides enhanced guidance for using fair value to measure assets and liabilities.  The standard applies 
whenever other standards require (or permit) assets or liabilities to be measured at fair value.  The standard 
does  not  expand  the  use  of  fair  value  in  any  new  circumstances.    SFAS  No.  157  is  effective  for  financial 
statements issued for fiscal years beginning after November 15, 2007, and interim periods within those fiscal 
years.    Earlier  application  is  encouraged,  provided  that  the  reporting  entity  has  not  yet  issued  financial 
statements  for  that  fiscal  year,  including  financial  statements  for  an  interim  period  within  that  fiscal  year.  
The Company will adopt this pronouncement effective periods beginning January 1, 2008.  The Company is 
currently evaluating the impact of adopting SFAS No. 157 on its financial statements. 

In February 2007, the FASB issued SFAS No. 159, "The Fair Value Option for Financial Assets and 
Financial Liabilities", which permits entities to measure many financial instruments and certain other items 
at fair value that are not currently required to be measured at fair value. An entity would report unrealized 
gains  and  losses  on  items  for  which  the  fair  value  option  has  been  elected  in  earnings  at  each  subsequent 
reporting date. The objective is to improve financial reporting by providing entities with the opportunity to 
mitigate volatility in reported earnings caused by measuring related assets and liabilities differently without 
having  to  apply  complex  hedge  accounting  provisions.  The  decision  about  whether  to  elect  the  fair  value 
option  is  applied  instrument  by  instrument,  with  a  few  exceptions;  the  decision  is  irrevocable;  and  it  is 
applied only to entire instruments and not to portions of instruments.  SFAS No. 159 requires disclosures that 
facilitate comparisons (a) between entities that choose different measurement attributes for similar assets and 
liabilities and (b) between assets and liabilities in the financial statements of an entity that selects different 
measurement attributes for similar assets and liabilities.  SFAS No. 159 is effective for financial statements 
issued for fiscal years beginning after November 15, 2007. Early adoption is permitted as of the beginning of 
a fiscal year provided the entity also elects to apply the provisions of SFAS No. 157. Upon implementation, 
an entity shall report the effect of the first remeasurement to fair value as a cumulative-effect adjustment to 
the opening balance of retained earnings. Since the provisions of SFAS No. 159 are applied prospectively, 
any  potential  impact  will  depend  on  the  instruments  selected  for  fair  value  measurement  at  the  time  of 
implementation.    The  Company  is  currently  evaluating  the  impact,  if  any,  adoption of  SFAS  No.  159  will 
have on its financial statements.

Results of Operations 

Comparison of the Year Ended December 31, 2006 and the Year Ended December 31, 2005 

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  $1,200,000  is 
reflected as deferred revenue on the balance sheet as of December 31, 2006.  We adopted SAB No. 104, 
"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 increased $249,750, or 8.9%, from $2,801,743 in fiscal 2005 
to  $3,051,493  in  fiscal  2006.    The  increase  was  due  primarily  to  an  increase  in  professional  fees  and 
expenses  incurred  related  to  preparing  for  compliance  with  Section 404  of  the  Sarbanes-Oxley  Act  of 
2002  and  professional  fees  related  to  the  Company's  proposed  transaction  with  Future  Systems,  Inc  in 
early 2006.  Higher general and administrative expenses during fiscal 2006 were also attributable to the 
higher stock compensation expense resulting from the adoption of SFAS No. 123R, effective January 1, 
2006. 

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 increased $1,608,857, or 93.7%, from $1,716,566 in fiscal 
2005  to  $3,325,423  in  fiscal  2006.    The  increase  was  due  primarily  to  the  fact  that  several  of  our drug 
candidates are continuing to undergo clinical trials and we have taken preliminary steps to prepare other 
drug  candidates  for  clinical  trials.    We  expect  that  research  and  development  expenses  will  continue  to 
increase as our other drug candidates move into the clinical trials phases of development.  Higher research 
and  development  expenses  during  fiscal  2006  were  also  attributable  to  the  higher  stock  compensation 
expense resulting from the adoption of SFAS No. 123R, effective January 1, 2006 and an increase in the 
number of outstanding shares subject to options during fiscal 2006 compared to fiscal 2005. 

33 

 
 
Patent Fees 

Our patent fees increased $112,549, or 63%, from $178,625 in fiscal 2005 to $291,174 in fiscal 
2006.  The increase was due primarily to an increase in the number of patent filings made during fiscal 
2006 compared to fiscal 2005. 

Depreciation and Amortization 

Depreciation expense increased $28,110, or 29.2%, from $96,400 in fiscal 2005 to $124,510 in 

fiscal 2006.  The increase was due primarily to the purchase of new laboratory equipment. 

Interest Expense 

Our  interest  expense  decreased  $97,165,  or  49.3%,  from  $196,816  in  fiscal  2005  to  $99,651  in 
fiscal  2006.    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 2006, we recorded $331,248 of interest income from the investment of our cash and cash 
equivalents  and  other  short-term  investments,  compared  to  $190,610  recorded  in  fiscal  2005.    The 
increase of $140,638, or 73.8%, was primarily due to higher cash and cash equivalent balances and higher 
interest rates during fiscal 2006. 

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  five  lead  drug  candidates,  Archexin,  RX-0047,  RX-5902,  Serdaxin  and 
Zoraxel. 

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-0047 and RX-5902 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. 

34 

 
 
Archexin 

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.    We  expect  to  file  a  complete  final  report  of  Phase  I  results  with  the  Food  and  Drug 
Administration this year. 

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  is  expected  to  begin  this  year  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 
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. 

RX-0047 and RX-5902 

RX-0047  and  RX-5902  are  both  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,  2006,  the  costs 
incurred for development of these compounds to date have been approximately $800,000 for RX-0047, 
and $300,000 for RX-5902.  The estimated cost to complete pre-clinical toxicology and Phase I clinical 
trials  is  estimated  to  be  approximately  $1,500,000 per  compound  for  a  total  of  $3,000,000.    These 
compounds may be entered into these Phase I clinical trials in 2008. 

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. 

35 

 
 
Serdaxin and Zoraxel 

Serdaxin and Zoraxel are scheduled to enter Phase II trials in 2007, subject to obtaining sufficient 
additional financing. We currently estimate that these studies will require approximately $4,000,000 and 
$3,000,000, respectively.  

Liquidity and Capital Resources 

Cash used in operating activities was $5,843,198 in fiscal 2006 compared to $4,131,450 in fiscal 
2005.  Fiscal 2006 operating cash flows reflect our loss from continuing operations of $6,486,003, offset 
by  net  non-cash  charges  of  $1,083,406  and  a  net  decrease  in  cash  components  of  working  capital  of 
$440,661.    Non-cash  charges  consist  of  depreciation  and  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.  Fiscal 2005 operating cash flows reflect our loss from 
continuing operations of $6,349,540, offset by net non-cash charges of $2,105,025 and a net increase in 
cash components of working capital of $113,065.  Non-cash charges consisted of $1,625,000 representing 
the  beneficial  conversion  feature  of  our  convertible  notes,  compensatory  stock  expense  of  $21,877, 
depreciation of $96,400 and stock option compensation expense of $436,748.  The increase in working 
capital primarily consisted of the beneficial conversion feature charge of $1,625,000, a $205,978 increase 
in  stock  option  compensation  expenses  and  a  $43,611  increase  in  depreciation,  offset  by  a  decrease  in 
accounts payable of $37,843. 

Cash used in investing activities of $52,952 in fiscal 2006 reflects capital expenditures of $52,952 
for the purchase of equipment.  Cash used in investing activities of $7,915,750 in fiscal 2005 consisted of 
purchases of short-term investments of $7,821,667, in addition to capital expenditures of $94,083 for the 
purchase of equipment. 

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.    Cash 
provided by financing activities of $13,326,179 in fiscal 2005 consisted of proceeds of $8,359,582 from 
the  issuance  of  common  stock  and  $5,150,000  from  proceeds  of  long-term  debt,  offset  by  principal 
payments on long-term debt of $183,403. 

For the years ended December 31, 2006 and 2005, we experienced net losses of $6,486,003 and 
$6,349,540, respectively.  Our accumulated deficit as of December 31, 2006 and 2005 were $20,690,326 
and $14,204,323, 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  2006,  we 
had a net decrease in cash and cash equivalents of $6,082,565.  This decrease primarily resulted from the 
cash used in operating activities of $5,843,198, investing activities of $52,952 and financing activities of 
$186,415. 

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.  

36 

 
 
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 and is payable based on 
the progress of the treatment over the effective period of the agreement.  We expect to make payments 
under the agreement in 2007. 

On August 17, 2004, we entered into an agreement with Formatech, Inc. to monitor and perform 
stability  studies  on  our  drug  candidate,  Archexin.    The  total  cost  of  these  services  is  $46,700.    For  the 
years ended December 31, 2006 and 2005, we paid $5,200 and $10,400, respectively, towards the cost of 
these studies.  A payment of $8,200 is due during 2007. 

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:

On  January 3,  2006  and  March 29,  2006,  we  contracted  with  Formatech  to  perform Archexin 
experiments  in  an  effort  to  develop  a  more  concentrated  dosage  form.    The  cost  of  the  project  was 
$57,000,  the  total  cost  of  which  was  paid  in  the  year  ended  December 31,  2006.    In  addition,  on 
January 6, 2006, we entered into a drug packaging agreement with Formatech for Phase II clinical trials 
of Archexin.  In accordance with the agreement, the estimated cost of the project is $128,250 plus pass 
through  expenses  (e.g.,  outsourced  testing),  of  which  138,540  was  paid  during  the  year  ended 
December 31, 2006. 

On  January 6,  2006,  we  contracted  with  Amarex,  LLC  to  conduct  Phase  II  clinical  studies.    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 
initiation fee of $149,061 due upon signing.  We paid $361,973 towards the cost of the study in the year 
ended December 31, 2006. 

On  March 1,  2006,  we  entered  into  a  research  program  with  Ewha  Woman's  University.    The 
effective period of the agreement was from March 1, 2006 to February 28, 2007.  In accordance with the 
agreement,  the  cost  of  the  research  program  was  $40,000  and  was  paid  upon  full  execution  of  the 
agreement.    The  Company  paid  $40,000  in  connection  with  the  agreement  during  the  year  ended 
December 31, 2006. 

37 

 
 
 
 
 
On  April 1,  2006,  we  entered  into  research  agreement  with  Korean  Research  Institute  of 
Bioscience  and  Biotechnology  to  evaluate  antitumor  activity,  toxicology,  pharmacokinetics  and 
mechanisms of action for RX-5902.  In accordance with the agreement, the estimated contract duration is 
twelve months for a cost of $120,000, which was paid during the year ended December 31, 2006. 

On  April 3,  2006,  we  contracted  with  UPM  Pharmaceuticals,  Inc.  to  develop  several  release 
formulation for Serdaxin and Zoraxel.  In accordance with the agreement, the estimated contract duration 
was seven months for an estimated cost of $443,975, of which $112,124 was paid during the year ended 
December 31,  2006.    The  service  costs  were  payable  based  upon  a  payment  schedule  related  to  certain 
milestones. 

On  April  19,  2006,  we  executed  definitive  agreements  with  Future  Systems,  Inc.  ("FSI"),  a 
Korean  stock  exchange  (KOSDAQ)  listed  information  technology  company  based  in  Seoul,  Korea. 
Pursuant  to  the  agreements,  we  would  transfer  to  FSI  exclusive  rights  and  a  non-exclusive  license  to 
develop,  manufacture,  and  sell  products  based  on  Rexahn’s  RX-0201,  RX-0047  and  RX-10100  drug 
candidates in certain territories for approximately $35.8 million, and simultaneously, FSI would issue and 
sell  4,326,854  shares  of  its  common  stock  to  us,  representing  approximately  28%  of  FSI’s  outstanding 
shares,  after  giving  effect  to  the  subscription.  The  investment,  of  approximately  $35.8  million,  would 
have made us the largest single stockholder of FSI. In addition, we entered into an agreement with FSI 
and Core F.G. Co., Ltd., the general partner of Triplewin Corporate Restructuring Partnership, the then-
current majority shareholder of FSI, with respect to the management of FSI in connection with redirecting 
FSI’s  business  focus  to  the  biopharmaceutical  industry.  Completion  of  the  transactions  was  subject  to 
customary closing conditions, including approval by FSI shareholders.  On June 8, 2006, we terminated 
the agreements entered into with FSI and Core F.G. Co., Ltd., including a share subscription agreement, 
an intellectual property assignment and license agreement and a management agreement, providing for, 
among other things, the assignment and license by us to FSI of certain intellectual property rights for our 
drug  candidates  in  specified  markets  and  the  acquisition  by  us  of  an  ownership  interest  in  FSI.  The 
termination followed a vote on the proposed transactions that was not approved by the FSI shareholders at 
a meeting in Seoul, Korea on June 7, 2006. 

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 
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.  
Over  the  next  12 months  we  expect  to  spend  a  minimum  of  approximately  $1.0  million  on  clinical 
development  for  Phase  II  clinical  trials  of  Archexin  (including  our  commitments  described  under 
"Contractual  Commitments"  of 
this  Item 6),  $2.6 million  on  general  corporate  expenses,  and 
approximately $216,000 on facilities rent.  We plan to initiate, subject to obtaining sufficient additional 
financing,  Phase  II  clinical  trials  of  Serdaxin  and  Zoraxel  beginning  in  the  second  half  of  2007  at  an 
additional cost of up to approximately $3 million.  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  and  Phase  I 
clinical trials for RX-5902, 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 $7 million through the end of 2007.  

38 

 
 
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.

Notes to Financial Statements 
December 31, 2006 and 2005 

1.  Operations and Organization  

Operations 

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. 

As part of the Acquisition Merger, the Company assumed the convertible notes further described in 
note 5 and the conversion price was adjusted to reflect the merger exchange ratio. 

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.

2.  Summary of Significant Accounting Policies (cont’d) 

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 current assets and 
current liabilities 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 
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.

g)  Earnings or Loss Per 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. 

The following potentially dilutive securities have been excluded from the diluted net earnings 
(loss)  per  share  calculations  for  the  years  ended  December  31,  2006  and  2005  because  their 
effect would have been antidilutive:

Based  Payment”  (“SFAS  No.  123R”),  which  requires  the  measurement  and  recognition  of 
compensation expense for all stock-based awards made to employees and directors based on the 
estimated grant date fair value of those awards.  SFAS No. 123R also requires forfeitures to be 
estimated  at  the  time  of  grant  and  revised,  if  necessary,  in  subsequent  periods  if  actual 
forfeitures  differ  from  those  estimates. The  fair  value  of  stock  options  is  calculated  using  the 
Black-Scholes option-pricing model.

2.  Summary of Significant Accounting Policies (cont’d) 

h) 

Stock-Based Compensation (cont’d) 

Prior  to  January  1,  2006,  the  Company  used  the  intrinsic  value  method  to  account  for 
stock-based compensation in accordance with Accounting Principles Board ("APB") Opinion 
No.  25,  "Accounting  for  Stock  Issued  to  Employees"  (“APB  No.25”),  and,  as  permitted  by 
SFAS No. 123, "Accounting for Stock-Based Compensation" ("SFAS No. 123"), provided pro 
forma disclosures of net income and earnings per common share as if the fair value methods 
had  been  applied  in  measuring  compensation  expense.    Under  the  intrinsic  value  method, 
compensation  cost  for  employee  stock  awards  was  recognized  as  the  excess,  if  any,  of  the 
deemed fair value for financial reporting purposes of the Company's common stock on the date 
of grant over the amount an employee must pay to acquire the stock.  Compensation cost was 
amortized over the vesting period.  The Company accounted for forfeitures as they occurred.  

The  Company  adopted  SFAS  No.123R  using  the  modified  prospective  transition  method, 
which  requires  the  recognition  of  compensation  expense  for  awards  granted  after  January 1, 
2006 that are expected to vest and for unvested awards granted prior to adoption of SFAS No. 
123R that are expected to vest. The compensation expense related to the awards granted prior to 
adoption  SFAS  No.  123R  is  based  on  the  grant  date  fair  value  estimated  in  accordance  with 
SFAS  No.  123  and  the  stock  based  compensation  expense  for  awards  granted  on  or  after 
January 1, 2006 is based on the grant date fair value estimated in accordance with SFAS No. 
123R.  The value of the portion of the award that is ultimately expected to vest is recognized as 
expense over the requisite service period. Prior period results have not been adjusted to reflect 
the adoption of SFAS No.123R.  

For  non-employee  stock-based  compensation,  the  Company  uses  the  fair  value  method  in 
accordance with SFAS No. 123 and Emerging Issues Task Force (“EITF”) 96-18, "Accounting  
for  Equity    Instruments    That  Are  Issued  to  Other  Than  Employees  for  Acquiring  or  in 
Conjunction with Selling, Goods or Services" (“EITF 96-18”).  

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.  Management 
does not consider this to be a significant credit risk as these banks and financial institutions are 
well-known. 

k)  Recent Accounting Pronouncements Affecting the Company 

In  July  2006,  FASB  issued  FASB  Interpretation  No. 48  (“FIN  48”),  “Accounting  for 
Uncertainty in Income Taxes”. FIN 48 clarifies the accounting for uncertainty in income taxes 
recognized  in  an  enterprise’s  financial  statements  in  accordance  with  SFAS  No. 109, 
“Accounting  for  Income  Taxes”.  FIN  48  prescribes  a  recognition  threshold  and  measurement 
attributable for the financial statement recognition and measurement of a tax position taken or 
expected  to  be  taken  in  a  tax  return.  FIN  48  also  provides  guidance  on  derecognition, 
classification, interest and penalties, accounting in interim periods, disclosures and transitions. 
FIN 48 is effective for fiscal years beginning after December 15, 2006. The Company does not 
expect the adoption of FIN 48 to have a material effect on its financial statements. 

In September 2006, FASB issued SFAS No. 157, “Fair Value Measurements”. SFAS No. 157 
provides enhanced guidance for using fair value to measure assets and liabilities. SFAS No. 157 
applies whenever other standards require (or permit) assets or liabilities to be measured at fair 
value. SFAS No. 157 does not expand the use of fair value in any new circumstances.  SFAS 
No. 157 is effective for financial statements issued for fiscal years beginning after November 
15,  2007,  and  interim  periods  within  those  fiscal  years.  Earlier  application  is  encouraged, 
provided  that  the  reporting  entity  has  not  yet  issued  financial  statements  for  that  fiscal  year, 
including financial statements for an interim period within that fiscal year.  The Company will 
adopt  SFAS  No.  157  effective  for  periods  beginning  January  1,  2008.    The  Company  is 
currently evaluating the impact, if any, adoption of SFAS No. 157 will have on our financial 
statements.

k)  Recent Accounting Pronouncements Affecting the Company(cont’d) 

In  September 2006,  the  Securities  and  Exchange  Commission  ("SEC")  staff  issued  Staff 
Accounting  Bulletin  ("SAB")  No. 108,  "Considering  the  Effects  of  Prior  Year  Misstatements 
when  Quantifying  Misstatements  in  Current  Year  Financial  Statements."  SAB  No.  108  was 
issued  to  provide  consistency  in  how  registrants  quantify  financial  statement  misstatements. 
The  Company  is  required  to  and  will  initially  apply  SAB  No.108  in  connection  with  the 
preparation  of  its  annual  financial  statements  for  the  year  ending  December 31,  2006.  The 
application of SAB No. 108 did not have a material effect on the Company’s financial position 
and results of operations.  

In  February  2007,  the  FASB  issued  SFAS  No.  159,  "The  Fair  Value  Option  for  Financial 
Assets and Financial Liabilities", which permits entities to measure many financial instruments 
and certain other items at fair value that are not currently required to be measured at fair value. 
An entity would report unrealized gains and losses on items for which the fair value option has 
been  elected  in  earnings  at  each  subsequent  reporting  date.  The  objective  is  to  improve 
financial reporting by providing entities with the opportunity to mitigate volatility in reported 
earnings caused by measuring related assets and liabilities differently without having to apply 
complex hedge accounting provisions. The decision about whether to elect the fair value option 
is applied instrument by instrument, with a few exceptions; the decision is irrevocable; and it is 
applied only to entire instruments and not to portions of instruments.  SFAS No. 159 requires 
disclosures  that  facilitate  comparisons  (a)  between  entities  that  choose  different  measurement 
attributes for similar assets and liabilities and (b) between assets and liabilities in the financial 
statements  of  an  entity  that  selects  different  measurement  attributes  for  similar  assets  and 
liabilities.  SFAS No. 159 is effective for financial statements issued for fiscal years beginning 
after  November  15,  2007.  Early  adoption  is  permitted  as  of  the  beginning  of  a  fiscal  year 
provided the entity also elects to apply the provisions of SFAS No. 157. Upon implementation, 
an entity shall report the effect of the first remeasurement to fair value as a cumulative-effect 
adjustment to the opening balance of retained earnings. Since the provisions of SFAS No. 159 
are applied prospectively, any potential impact will depend on the instruments selected for fair 
value  measurement  at  the  time  of  implementation.    The  Company  is  currently  evaluating  the 
impact, if any, adoption of SFAS No. 159 will have on its financial statements.

the  Company  entered 

On  February  10,  2005, 
licensing  agreement  with  Revaax 
Pharmaceuticals LLC ("Revaax"), whereby the Company received an exclusive, worldwide, royalty 
bearing  license,  with  the  right  to  sub-license,  of  Revaax's  licensed  technology  and  products.    The 
agreement  calls  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 the 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%.  As  at  December  31,  2006  the  outstanding  balance  was  paid.  
Amortization  expense  was  $17,919  and  $16,326  for  2006  and  2005,  respectively.  The  Company 
tested the asset for impairment and found none.

5.  Long-Term Convertible Debt 

On  February  28,  2005,  the  Company  issued,  in  a  transaction  exempt  from  registration  under  the 
Securities Act of 1933, as amended, $3,850,000 aggregate principal amount of 6% convertible notes 
due on February 28, 2008. The notes were subject to conversion into shares of common stock of the 
Company,  at  the  holder's  option,  at  any  time  from  and  after  the  earlier  of  (i)  the  date  of  the  first 
anniversary  of  the  closing  of  the  Acquisition  Merger  (May  13,  2006)  or  (ii)  May  26,  2006  to  the 
maturity date, February 28, 2008. The notes would be automatically converted upon (i) the closing 
of the sale of all or substantially all of the assets of the Company or any merger, consolidation or 
other business combination or (ii) the maturity date. The conversion price was equal to the lesser of 
$1.00  per  share  (as  adjusted  in  the  Acquisition  Merger)  and  a  floating  price  determined  by  the 
average of three lowest current market prices of Company common stock during the 40 calendar day 
period  immediately  preceding  conversion.    On  May  13,  2006,  owners  of  the  convertible  notes 
exercised their rights to convert the entire principal amount of the notes into 3,850,000 shares of the 
Company’s common stock at a conversion price of $1.00 per share.   

On August 8, 2005, the Company completed a private placement of $1.3 million aggregate principal 
amount of convertible notes. The holders of these notes were entitled any time after September 19, 
2005 until August 8, 2008, or upon the occurrence and continuance of any of the events of default, to 
convert  the  principal  amount  of  any  convertible  notes  or  portions  thereof  into  common  stock  at  a 
conversion  price  of  $2.00  per  share.  The  Company  evaluated  this  transaction  and  determined  that 
based  on  the  market  price  of  the Company's  common  stock  on  August  8,  2005  of  $4.50  per 
share, there  was  an  associated  deferred beneficial  conversion  feature  of  $2.50  per  share,  or  a total 
of $1,625,000, and recorded such amount as interest to be recognized over the term of the note. On 
December 2, 2005, the note holders exercised their rights to convert the entire principal amount of 
the notes into an aggregate of 650,000 shares of the Company's common stock. Upon conversion, the 
deferred beneficial conversion feature of $1,625,000 was recorded as an increase in net loss and an 
increase in the value of additional paid in capital.

6.  Deferred Revenue 

In 2003, the Company entered into a collaborative research agreement with Rexgene Biotech Co., 
  Rexgene  is  engaged  in  the  development  of 
Ltd.  ("Rexgene"),  a  minority  shareholder. 
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 each of the years ended December 31, 2006 and 
2005.  The remaining $1,200,000 at December 31, 2006 (2005-$1,275,000) 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 at least 2009.

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.  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,  subject  to  the  fulfillment  of  certain  conditions  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  Company's  Stock  Option  Plan  approved  at  the  Annual  Meeting  of  the

available for issuance (2005- 1,182,500).

8.  Stock-Based Compensation (cont'd) 

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 
No.  25,  and  related  interpretations.  SFAS  No.  123R  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 in SEC SAB No. 
107, which provides the SEC staff's views regarding the interaction between SFAS No. 123R and 
certain  SEC  rules  and  regulations  and  provides  interpretations  with  respect  to  the  valuation  of 
share-based payments for public companies. 

Prior to January 1, 2006, the Company accounted for similar employee transactions in accordance 
with  APB  No.  25  which  employed  the  intrinsic  value  method  of  measuring  compensation  cost. 
Accordingly, compensation expense was not recognized for employee stock options if the exercise 
price of the option equaled or exceeded the fair value of the underlying stock at the grant date. 

While  SFAS  No.  123,  for  employee  options,  encouraged  recognition  of  the  fair  value  of  all 
stock-based  awards  on  the  date  of  grant  as  expense  over  the  vesting  period,  companies  were 
permitted  to  continue  to  apply  the  intrinsic  value-based  method  of  accounting  prescribed  by  APB 
No. 25 and disclose certain pro forma amounts as if the fair value approach of SFAS No. 123 had 
been  applied.    In  December  2002,  SFAS  No.  148,  "Accounting  for  Stock-Based  Compensation—
Transition  and  Disclosure,  an  amendment  of  SFAS  No.  123",  was  issued,  which,  in  addition  to 
providing  alternative  methods  of  transition  for  a  voluntary  change  to  the  fair  value  method  of 
accounting for stock-based employee compensation, required more prominent pro-forma disclosures 
in  both  the  annual  and  interim  financial  statements.  The  Company  complied  with  these  disclosure 
requirements for all applicable periods prior to January 1, 2006. 

In adopting SFAS No. 123R, the Company applied the modified prospective approach to transition. 
Under  the  modified  prospective  approach,  the  provisions  of  SFAS  No.  123R  are  to  be  applied  to 
new  employee  awards  and  to  employee  awards  modified,  repurchased,  or  cancelled  after  the 
required  effective  date.  Additionally,  compensation  cost  for  the  portion  of  employee  awards  for 
which  the  requisite  service  has  not  been  rendered that  are  outstanding  as  of  the  required  effective 
date  will  be  recognized  as  the  requisite  service  is  rendered  on  or  after  the  required  effective  date. 
The  compensation  cost  for  that  portion  of  employee  awards  will  be  based  on  the  grant-date  fair 
value of those awards as calculated for either recognition or pro-forma disclosures under SFAS No. 
123.

8.  Stock-Based Compensation (cont'd) 

As  a  result  of  the  adoption  of  SFAS  No.  123R,  the  Company's  results  of  operations  for  the  year 
ended December 31, 2006 include share-based employee compensation expense totaling $656,169. 
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  net  deferred  tax  assets.    No  stock  option  compensation  expense  was 
recorded under APB No. 25 in the Statements of Operations for the year ended December 31, 2005. 

Employee stock option compensation expense in 2006 is the estimated fair value of options granted 
amortized  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  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  $377,787  for  the  year  ended 
December 31, 2006 and $436,748 for the year ended December 31, 2005.  Such amounts have been 
included in the Statements of Operations in general and administrative and research and development 
expenses. 

The weighted average estimated fair value of stock options granted in the year ended December 31, 
2006 and 2005 was $0.83 and $0.77, respectively.  The fair value of options at the date of grant was 
estimated  using  the  Black-Scholes  option  pricing  model.  During  2006,  the  Company  took  into 
consideration  guidance  under  SFAS  No.  123R  and  SAB  No.  107  when  reviewing  and  updating 
assumptions. The expected volatility is based upon historical volatility of the Company's stock and 
other contributing factors. The expected term is based upon the contract life with non-employees.

The Company has tax losses available to be applied against future years income.  Due to the losses 
incurred in the current year and expected future operating results, management determined that it is 
more  likely  than  not  that  the  deferred  tax  asset  resulting  from  the  tax  losses  available  for 
carryforward and stock option compensation expense will not be realized through the reduction of 
future  income  tax  payments.  Accordingly  a  100%  valuation  allowance  has  been  recorded  for 
deferred income tax assets. 

As of December 31, 2006 and 2005, the Company had approximately $20,838,000 and $14,204,000, 
respectively, of federal and state net operating loss carryforwards available to offset future taxable 
income; such carryforwards expire in various years through 2024. 

10.  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  initiation  fee  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,  2006,  the 
total  value  of  these  agreements  was  approximately  $1,800,000  (2005-$1,900,000)  and  the 
Company  had  made  payments  totaling  $1,150,000  under  the  terms  of  the  agreements  as  at 
December 31, 2006 (2005-$1,000,000).  All of these agreements may be terminated by either 
party upon appropriate notice as stipulated in the respective agreements.

10.  Commitments and Contingencies (cont’d) 

b)  On April 19, 2006, the Company executed definitive agreements with Future Systems, Inc. ("FSI"), a Korean 
stock  exchange  (KOSDAQ)  listed  information  technology  company  based  in  Seoul,  Korea.  Pursuant  to  the 
agreements,  the  Company  would  transfer  to  FSI  exclusive  rights  and  a  non-exclusive  license  to  develop, 
manufacture,  and  sell  products  based  on  Rexahn’s  RX-0201,  RX-0047  and  RX-10100  drug  candidates  in 
certain  territories  for  approximately  $35.8  million,  and  simultaneously,  FSI  would  issue  and  sell  4,326,854 
shares of its common stock to the Company, representing approximately 28% of FSI’s outstanding shares, after 
giving  effect  to  the  subscription.  The  investment,  of  approximately  $35.8  million,  would  have  made  the 
Company the largest single stockholder of FSI. In addition, the Company entered into an agreement with FSI 
and Core F.G. Co., Ltd., the general partner of Triplewin Corporate Restructuring Partnership, the then-current 
majority  shareholder  of  FSI,  with  respect  to  the  management  of  FSI  in  connection  with  redirecting  FSI’s 
business  focus  to  the  biopharmaceutical  industry.  Completion  of  the  transactions  was  subject  to  customary 
closing  conditions,  including  approval  by  FSI  shareholders.   On  June  8,  2006,  the  Company  terminated  the 
agreements  entered  into  with  FSI  and  Core  F.G.  Co.,  Ltd.,  including  a  share  subscription  agreement,  an 
intellectual  property  assignment  and  license  agreement  and  a  management  agreement,  providing  for,  among 
other things, the assignment and license by the Company to FSI of certain intellectual property rights for the 
Company's drug candidates in specified markets and the acquisition by the Company of an ownership interest 
in  FSI.  The  termination  followed  a  vote  on  the  proposed  transactions  that  was  not  approved  by  the  FSI 
shareholders at a meeting in Seoul, Korea on June 7, 2006. 

c)  On  September  12,  2005  the  Company  and  three  of  its  key  executives  entered  into  employment  agreements. 
Two of the three agreements expire on September 12, 2007 and result in an annual commitment of $360,000. 
One agreement expires on September 12, 2010 and results in an annual commitment of $350,000. 

d) 

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 are as follows:

e)  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.

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,  2006  and  2005  and  the  related  statements  of  operations,  stockholders’ 
equity  (deficit)  and  cash  flows  for  the  years  ended  December  31,  2006  and  2005  and  the  cumulative 
period  from  inception  (March  19,  2001)  to  December  31,  2006.    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 provides 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, 2006 and 2005 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,  2006,  in  conformity  with  accounting  principles  generally  accepted  in  the 
United States of America.

this report is accumulated and communicated to the Company's management, including its principal executive 
officer  and  principal  financial  officer,  as  appropriate,  to  allow  timely  decisions  regarding  required  disclosure.  
During  the  last  fiscal  quarter  to  which  this  report  relates,  there  were  no  changes  in  the  Company's  internal 
controls or other factors that could significantly affect these controls subsequent to the date of their evaluation 
and there were no corrective actions with regard to significant deficiencies and material weaknesses.

1 Represents option awards under the Company's Stock Option Plan which vest 30%, 30% and 40% on the first, 

second and third anniversaries of the date of grant. 

2 Dr. Steinfels resigned from all his positions with the Company in September 2006. 

Stock Option Plan 

In July 2003 the board of directors adopted, and in August 2003 our stockholders approved, the Rexahn 
stock option plan.  In connection with the Merger, we assumed the plan and converted all outstanding options to 
purchase Rexahn common stock into options to purchase Rexahn Pharmaceuticals common stock.  The number 
of shares subject to the converted options was multiplied by five and the exercise price per share was divided by 
five. 

The plan permits grants to be made from time to time as non-qualified stock options or incentive stock 

options. 

Administration.  The stock option plan is administered by the board of directors.  In the alternative, the 
board may appoint a stock option committee to administer the plan on behalf of the board.  The plan is currently 
administered by our board of directors.  In order to meet the requirements of the rules under Section 16 of the 
Securities  Exchange  Act  of  1934,  as  amended  (the  "Exchange  Act"),  all  future  grants  under  the  plan  will  be 
made by a committee whose members are "non-employee directors" as defined for purposes of Section 16 of the 
Exchange  Act  and  outside  directors  within  the  meaning  of  Section 162(m)  of  the  Internal  Revenue  Code  of 
1986, as amended. 

NY3 - 434732.20

Participation.    The  persons  to  whom  grants  are  made  under  the  plan  will  be  selected  from  time  to  time  by  the 

stock option committee in its sole discretion from among our employees, officers, directors and consultants.  

Shares Subject to Stock Option Plan.  The plan authorizes the issuance or delivery of an aggregate of 6,992,500 
shares of common stock.  Shares of common stock subject to the unexercised, undistributed or unearned portion of any 
terminated or forfeited grant under the plan will be available for further awards.  

Stock Options.  The plan authorizes grants of stock options, which may be either incentive stock options eligible 

for special tax treatment or non-qualified stock options.  Incentive stock options may be granted only to our employees. 

Under the provisions of the plan authorizing the grant of stock options:  

• 

• 

• 

the option price will be determined by the stock option committee; provided, however, that the option price 
for an incentive stock option may not be less than 100% of the fair market value of the shares of our common 
stock  on  the  date  of  grant  (110%  for  grants  to  an  optionee  owning  more  than  10%  of  our  total  combined 
voting power);  

the term during which each stock option may be exercised will be determined by the stock option committee; 
provided, however, that incentive stock options generally may not be exercised more than ten years from the 
date  of  grant  (five  years  for  grants  to  an  optionee  owning  more  than  10%  of  our  total  combined  voting 
power); and  

at  the  time  of  exercise  of  a  stock  option  the  option  price  must  be  paid  in  full  in  cash  or  in  shares  of  our 
common stock or in a combination of cash and shares of our common stock or by such other means as the 
stock option committee may determine.  

All  grants  made  under  the  plan  will  be  evidenced  by  a  letter  to  the  optionee,  together  with  the  terms  and 
conditions  applicable  to  the  grants,  as  determined  by  the  stock  option  committee  consistent  with  the  terms  of  the  plan.  
These terms and conditions will include, among other things, a provision describing the treatment of grants in the event of 
certain  triggering  events,  such  as  a  sale  of  a  majority  of  the  outstanding  shares  of  our  common  stock,  a  merger  or 
consolidation in which we are not the surviving company, and termination of an optionee's employment, including terms 
relating to the vesting, time for exercise, forfeiture or cancellation of a grant under such circumstances.  

Under the plan, stock options may not be granted after August 5, 2013.  

Tax Matters.  The following is a brief summary of the material federal income tax consequences of benefits under 

the plan under present law and regulations: 

(a) 

Incentive Stock Options.  The grant of an incentive stock option will not result in any immediate tax consequences 
to us or the optionee.  An optionee will not realize taxable income, and we will not be entitled to any deduction, 
upon the timely exercise of an incentive stock option, but the excess of the fair market value of the shares of our 
common stock acquired over the option exercise price will be includable in the optionee's "alternative minimum 
taxable income" for purposes of the alternative minimum tax.  If the optionee does not dispose of the shares of our 
common stock acquired within one year after their receipt, and within two years after the option was granted, gain 
or  loss  realized  on  the  subsequent  disposition  of  the  shares  of  our  common  stock  will  be  treated  as  long-term 
capital gain or loss.  Capital losses of individuals are deductible only against capital gains and a limited amount of 
ordinary income.  In the event of an earlier disposition, the optionee will realize ordinary income in an amount 
equal  to  the  lesser  of  (i) the  excess  of  the  fair  market  value  of  the  shares  of  our  common  stock  on  the  date  of 
exercise over the option exercise price or (ii) if the disposition is a taxable sale or exchange, the amount of any 
gain realized.  Upon such a disqualifying disposition, we will be entitled to a deduction in the same amount as the 
optionee realizes such ordinary income. 

NY3 - 434732.20 

73 

 
(b) 

Non-qualified Stock Options.  In general, the grant of a non-qualified stock option will not result in any 
immediate tax consequences to us or the optionee.  Upon the exercise of a non-qualified stock option, 
generally the optionee will realize ordinary income and we will be entitled to a deduction, in each case, 
in an amount equal to the excess of the fair market value of the shares of our common stock acquired at 
the time of exercise over the option exercise price.  

Amendment, Suspension or Termination of Stock Option Plan.  Our board of directors may at any time 
amend, suspend or discontinue the plan and the stock option committee may at any time alter or amend awards 
and  award  agreements  made  thereunder  to  the  extent  permitted  by  law,  provided  that  no  such  alteration  or 
amendment  will  be  effective  without  the  approval  of  our  stockholders  to  the  extent  that  such  approval  is 
necessary  to  comply  with  any  tax  or  regulatory  requirement  applicable  to  the  plan  and  no  such  alteration  and 
amendment will impair the rights of any recipient of grants without such recipient's consent.  In the event of any 
change in or affecting the  outstanding shares of our common stock by reason of a stock dividend, stock split, 
combination of shares or other similar event, our board of directors will make such amendments to the plan and 
outstanding  grants  and  award  agreements,  and  make  such  adjustments  and  take  such  actions  as  it  deems 
appropriate  and  equitable.    In  the  event  of  any proposed  change  in  control  (as  defined  by  the  plan),  the  stock 
option committee will take such action as it deems appropriate and equitable to effectuate the purposes of the 
plan  and  to  protect  the  optionees,  including,  but  not  limited  to,  accelerating  or  changing  the  exercise  dates  of 
stock  options,  payment  of  appropriate  consideration  for  the  cancellation  and  surrender  of  stock  options  or  if 
equity  securities  of  any  other  corporation  will  be  exchanged  for  outstanding  shares  of  our  common  stock, 
providing for stock options to become options with respect to such other equity securities.  For purposes of the 
plan, a change in control means the sale, exchange or disposition of substantially all of our assets or any merger, 
share exchange, consolidation or other reorganization or business combination in which we are not the surviving 
corporation or in which our stockholders become entitled to receive cash, securities of our company other than 
voting common stock or securities of another issuer. 

Employment Agreements 

Chang H. Ahn.  Dr. Ahn's employment agreement dated September 12, 2005 provides that Dr. Ahn will 
serve  as  Chief  Executive  Officer  ("CEO") of  the  Company  until  September 12,  2010,  unless  Dr.  Ahn's 
employment  is  sooner  terminated  as  further  described  below.    If  Dr.  Ahn's  employment  continues  beyond 
September 12,  2010,  such  employment  will  become  "at-will,"  unless  his  employment  agreement  is  expressly 
extended. 

Dr. Ahn will be paid an annual base salary of $350,000, subject to periodic review and potential increase 
at the Board's sole discretion.  During his employment, Dr. Ahn will be eligible to receive an annual cash bonus, 
as  determined  by  the  Board  in  its  sole  discretion,  not  exceeding  75%  of  his  annual  base  salary.    In  order  to 
receive such cash bonus, Dr. Ahn must be actively employed by the Company on the date on which such cash 
bonus is scheduled to be paid to him.  Dr. Ahn will also be eligible to receive options to purchase shares of the 
Company's  stock,  to  be  awarded  in  the  Board's  sole  discretion  under  the  Company's  Stock  Option  Plan  (the 
"Stock Option Plan").  In addition, Dr. Ahn will be eligible for additional bonus in the form of cash and/or stock 
that may be awarded in the Board's sole discretion. 

If  Dr.  Ahn  suffers  a  "Disability"  (as  defined  in  his  employment  agreement),  the  Board,  in  its  sole 
discretion, may terminate the employment agreement immediately upon written notice to Dr. Ahn.  The Board 
may  terminate  Dr.  Ahn's  employment  with  or  without  "Cause"  (as  defined  in  his  employment  agreement)  or 
Dr. Ahn may voluntarily terminate his employment, in each case, upon 30 days' written notice. 

NY3 - 434732.20 

74 

 
If the Company terminates Dr. Ahn's employment without Cause (other than following a "Change of Control" (as 
defined  in  his  employment  agreement)),  the  Company  will  pay  to  Dr.  Ahn  (1) his  then  current  base  salary  through  the 
termination date, (2) any accrued but unused vacation days as of the termination date, (3) a pro-rata portion of Dr. Ahn's 
bonus  for  fiscal  year  in  which  the  termination  occurs,  assuming a  bonus  of  75%  of  his  then  current  base  salary,  (4) an 
amount  equaling  6 months  of  his  then  current  base  salary,  and  (5) continued  coverage  under  the  Company's  health 
insurance plan for 18 months.  If Dr. Ahn's employment is terminated by the Board without Cause within the one-year 
period immediately following a Change of Control, the Company will pay to Dr. Ahn the termination compensation and 
benefits  subject  to  the  conditions  as  described  in  clauses (1),  (2),  (3) and  (5) of  the  first  sentence  of  this  paragraph.    In 
addition,  the  Company  will  pay  to  Dr.  Ahn  an  amount  equaling  his  then  current  base  salary  for  the  greater  of  the 
remainder of the term of his employment under the employment agreement or a period of one year.  The payments and 
benefits  to  Dr.  Ahn  described  in  this  paragraph  are  subject  to  reimbursement  by  Dr.  Ahn  and  reduction  by  any 
compensation  or  benefits  actually  earned  or  received  by  Dr.  Ahn  as  an  employee  of  or  consultant  to  any  other  entity 
during the period for which Dr. Ahn continues to receive salary payments post-termination, the requirement that Dr. Ahn, 
in good faith, seek other employment in a comparable position and otherwise mitigate the Company's obligations and Dr. 
Ahn's execution of a customary release in a form satisfactory to the Company. 

Tae  Heum  Jeong.    Mr.  Jeong's  employment  agreement  dated  September 12,  2005  provides  that  Mr. Jeong  will 
serve  as  Chief  Financial  Officer  of  the  Company  until  September 12,  2007,  unless  Mr.  Jeong's  employment  is  sooner 
terminated  as  further  described  below.    If  Mr.  Jeong's  employment  continues  beyond  September 12,  2007,  such 
employment will become "at-will," unless his employment agreement is expressly extended. 

Mr. Jeong will be paid an annual base salary of $160,000, subject to periodic review and potential increase at the 
Board's  sole  discretion.    During  his  employment,  Mr.  Jeong  will  be  eligible  to  receive  an  annual  cash  bonus,  as 
determined  by  the  CEO  in  his  sole  discretion,  in  an  amount  not  exceeding  50%  of  his  annual  base  salary.    In  order  to 
receive such cash bonus, Mr. Jeong must be actively employed by the Company on the date on which such cash bonus is 
scheduled to be paid to him.  Mr. Jeong will also be eligible to receive options to purchase shares of the Company's stock, 
to  be  awarded  in  the  Board's  sole  discretion  under  the  Stock  Option  Plan.    In  addition,  Mr.  Jeong  will  be  eligible  for 
additional bonus in the form of cash and/or stock that may be awarded in the Board's sole discretion. 

The  circumstances  under  which  Mr.  Jeong's  employment  agreement  may  terminate  and  the  related  terms  and 
conditions of any payments and benefits payable to Mr. Jeong as a result of the termination are substantially similar to Dr. 
Ahn's employment agreement, except that if the Company terminates Mr. Jeong's employment without Cause (other than 
following a Change of Control), the Company will pay to Mr. Jeong a pro-rata portion of Mr. Jeong's bonus for fiscal year 
in which the termination occurs, assuming a bonus of 50% of his then current salary.   

Mr. Jeong is restricted from soliciting employees or customers of the Company during and for 12 months after the 

employment period. 

George Steinfels.  Dr. Steinfels' employment agreement dated September 12, 2005 provided that Dr. Steinfels 
serve as Chief Business Officer of the Company until September 12, 2007, unless Dr. Steinfels' employment is sooner 
terminated as further described below.  If Dr. Steinfels' employment continued beyond September 12, 2007, such 
employment would become "at will," unless his employment agreement was expressly extended. On September 1, 2006, 
George Steinfels resigned from his positions with the Company. 

Dr.  Steinfels  was  paid  an  annual  base  salary  of  $200,000,  which  was  subject  to  periodic  review  and  potential 
increase at the Board's sole discretion.  During his employment, Dr. Steinfels was eligible to receive an annual cash bonus, 
as determined by the CEO in his sole discretion, in an amount not exceeding 50% of his annual base salary.  In order to 
receive such cash bonus, Dr. Steinfels must have been actively employed by the Company on the date on which such cash 
bonus  was  scheduled  to  be  paid  to  him.    Dr.  Steinfels,  during  his  employment,  was  also  eligible  to  receive  options  to 
purchase  shares  of  the  Company's  stock,  to be  awarded  in  the  Board's  sole  discretion  under  the  Stock Option  Plan.   In 
addition, Dr. Steinfels was eligible for additional bonus in the form of cash and/or stock that may have been awarded in 
the Board's sole discretion. 

NY3 - 434732.20 

75 

 
The  circumstances  under  which  Dr.  Steinfels  employment  agreement  may  terminate  and  the  related  terms  and 
conditions of any payments and benefits payable to Dr. Steinfels as a result of the termination were substantially similar to 
Mr. Jeong's employment agreement.  Dr. Steinfels resigned from all his positions with the Company in September 2006 and 
no additional amounts were paid in connection with the termination of his employment agreement. 

Dr. Steinfels is restricted from soliciting employees or customers of the Company during and for 12 months after the 

employment period. 

To the extent that any amounts payable to Dr. Ahn, or Mr. Jeong described above constitute an amount payable under 
a "nonqualified deferred compensation plan," as defined in Section 409A, following a "separation from service," as defined in 
Section 409A,  such  payment  will  not  be  made  until  the  date  that  is  six  months  following  the  executive's  "separation  from 
service," but only if the executive is then deemed to be a "specified employee" under Section 409A. 

To the extent that any amounts payable to Dr. Ahn, Mr. Jeong or Dr. Steinfels described above constitute an amount 
payable  under  a  "nonqualified  deferred  compensation  plan,"  as  defined  in  Section 409A,  following  a  "separation  from 
service,"  as  defined  in  Section 409A,  such  payment  will  not  be  made  until  the  date  that  is  six  months  following  the 
executive's  "separation  from  service,"  but  only  if  the  executive  is  then  deemed  to  be  a  "specified  employee"  under 
Section 409A.

Item 12.  Certain Relationships and Related Transactions; and Director Independence 

Related Transactions 

On  February 6,  2003,  Rexahn  entered  into  a  research  collaboration  agreement  with  Rexgene  Biotech 
Co.,  Ltd.    ("Rexgene"),  the  holder  of  approximately  10.32%  of  outstanding  common  stock.    Dr. Young-Soon 
Park, holder of approximately 19.93% of outstanding common stock and a director, served as the Chairman of 
Rexgene Biotech until 2003.   

Under  the  agreement  we  and  Rexgene  agreed  to  jointly  develop  and  implement  a  research  and 
development  plan  (including  conducting  clinical  and  animal  trials  in  various  countries  and  exchanging  data 
derived  from  such  trials)  in  order  to  register  Archexin,  one  of  our  drug  candidates,  for  sale  and  use  in  Asian 
countries.  We contributed a license to technology relating to Archexin, and Rexgene contributed $1,500,000 as 
initial  contributions  under  the  agreement.    In  addition,  Rexgene  agreed  to  conduct  clinical  trials  in  Asian 
countries at its own expense, and we agreed to conduct clinical and animal trials in the United States and in non-
Asian countries at our own expense.  We and Rexgene also agreed to share data, improvements, developments, 
discoveries  and  inventions  resulting  from  the  agreement.    Under  the  agreement,  Rexgene  also  received  an 
exclusive  license  from  us  to  exploit  any  results  from  the  research  development  in  Asian  countries,  and  we 
received an exclusive license to exploit any results from the research and development everywhere in non-Asian 
countries.  Pursuant to the terms of the agreement, Rexgene also agreed to pay us 3% of the profits derived from 
the sale of Archexin in Asian countries.  The agreement, if not earlier terminated by either us or Rexgene, will 
terminate  on  the  expiration  of  the  patents  resulting  from  the  agreement,  or  if  no  such  patents  are  granted,  20 
years from February 6, 2003. 

On  September 3,  2003,  we  entered  into  a  joint  research  and  development  agreement  with  Chong  Kun 

Dang Pharmaceutical Corp. ("CKD"), the holder of approximately 6.96% of outstanding common stock.   

Under the agreement, we and CKD agreed to cooperate in the research and development of a variety of 
new pharmaceutical compounds for human use in their own capacities.  Each of CKD and us has performed and 
will continue to perform research, development and other obligations under the agreement at its own expense.  
CKD and Rexahn equally own all information, data, discoveries and all other results, either patentable or non-
patentable, made or developed in connection with or arising out of the agreement.  All profits derived from or in 
connection with the agreement will be allocated to CKD and us in proportion to relative contributions based on 
certain ratios, which vary depending upon a particular research and development phase during which the profits 
are earned.  The agreement, if not earlier terminated by either us or CKD, will last until the expiration of any 
intellectual property rights pertaining to information, data, discoveries and all other results made or developed in 
connection with or arising out of the agreement.   

Director Independence 

Charles  Beever,  Kwang  Soo  Cheong,  Y.  Michele  Kang  and  David  McIntosh,  serve  as  independent 
directors  under  the  applicable  listing  standards  of  the  Nasdaq  Stock  Market,  as  may  be  modified  or
