(cid:190) Corporate Profile  

Rexahn  is  a  clinical  stage  biopharmaceutical  company  dedicated 

to the discovery, development, and commercialization of innovative 

treatments for cancer, diseases of the central nervous system (CNS), 

and unmet medical needs.  

We have a team of dedicated professionals and intend to leverage 

our drug-discovery technologies, scientific expertise, and 

development know-how to provide cancer and CNS drugs with 

greater clinical benefits for patients.  Located in Maryland’s I-270 

technology corridor, the nation’s third largest biocluster, our location 

provides us the opportunity for collaboration with world-class 

institutions, such as the National Institutes of Health (NIH), and convenient access to the Food and Drug 

Administration (FDA). 

Our research and development focus in oncology is on signal transduction inhibitors that directly target 

the communication systems of cancer cells.   Disrupting the signals responsible for disease progression 

offers a more targeted and less toxic therapeutic approach for cancer treatment. 

In the area of neuroscience, our research and development is focused on disorders of the central 

nervous system.  Our lead neuroscience drug candidate has demonstrated significant activity against 

anxiety and depression.  Preclinical research is also expanding the potential indications of this compound 

series to include treatment of male sexual dysfunctions.

(cid:190) Pipeline Overview  

Oncology 

According to the American Cancer Society’s Cancer 

Facts & Figures 2006, cancer is the second leading 

cause of death among Americans and is responsible 

for one of every four deaths in the United States.  In 

2006, more than 560,000 Americans are expected to 

die of cancer and close to 1.4 million new cases are 

expected to be diagnosed, not including non-

invasive cancers or non-melanoma skin cancer.  

Annually, cancer patients spend $17 billion in the US 

and $31 billion worldwide on anti-cancer medications.  

Oncology Drug Candidates  

Rexahn’s therapeutic focus in oncology drug development is on signal inhibitors.  Our product 

candidates have shown an ability to inhibit the proliferation of cancer cells, to induce programmed cell 

death and/or to reverse radiation resistance.  

RX-0201: Akt inhibitor. RX-0201, an ASO-based inhibitor of Akt-1, will soon conclude Phase I clinical trials at 

Georgetown University and the University of Alabama.  To date, studies have demonstrated that, at 

nanomolar concentrations, RX-0201 significantly inhibits both proliferation of various cancer cells and 

growth of tumors in animal models. RX-0201 is expected to enter Phase II clinical trials in 2006. 

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

regulating 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.  

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

ranges. RX-5902 is a candidate for oral administration based on its excellent oral bioavailability in animal 

pharmacokinetics studies.  RX-5902 will soon begin GLP toxicology tests in animals and is expected to 

begin Phase I clinical trials in late 2006 or early 2007. 

RX-0047: HIF Transcription Factor Inhibitor. Tumors cannot grow without blood vessels that supply cancer 

cells with oxygen and nutrients.  HIF-1 transcription factor is a key regulating mechanism of new blood 

2

vessel formation, a process known as angiogenesis.  HIF is over expressed in a broad range of human 

cancers, such as brain, breast, cervix, colon, kidney, liver, lung, ovarian, pancreatic, prostate, skin, and 

stomach cancers. HIF-1 over-expression is associated with disease progression, metastasis, and/or 

radiation resistance.  As a result, HIF-1 appears to be an important target in the treatment of cancer.  

Preclinical studies have demonstrated that RX-0047 is a potent inhibitor of HIF-1, limiting the proliferation 

of various cancer cells at nanomolar concentrations, reversing radiation resistance, and inhibiting the 

growth of tumors and metastasis in animal models. 

Neuroscience  

Worldwide, the market for CNS treatments was $62 billion in 2004. Depression and anxiety disorders 

accounted for $18 billion, alone.  It is estimated that depressive disorders, such as major depression, 

bipolar disorder and dysthymic disorder affect over 18.8 million Americans and over 121 million people 

worldwide. Nearly 60% of patients with depression also suffer from anxiety.  According to the National 

Institutes of Mental Health, more than 19 million adult Americans ages 18 to 54 have anxiety disorders, 

including generalized anxiety disorder, panic disorder, social anxiety disorder, obsessive-compulsive 

disorder, and post-traumatic stress disorder.   

Neuroscience Drug Candidate 

Our neuroscience portfolio of compounds has therapeutic opportunities for the treatment of anxiety and 

depression and potential opportunities for the treatment of male sexual disorders, such as erectile 

dysfunction and premature ejaculation. 

RX-10100: RX-10100 is the lead compound in our neuroscience program.  RX-10100 has demonstrated 

microgram/kilogram potency in animal models of anxiety. Microdialysis studies in rats demonstrate that 

when RX-10100 is administered, dopamine and serotonin levels in the brain increase.  In addition, animals 

treated with RX-10100 show normal activity in open field tests and normal learning and memory in the 

Morris water maze, indicating that RX-10100, unlike other marketed anxiety/depression drugs, may not 

induce side effects on motor activity and cognition function.   RX-10100 has also shown potential for 

treatment of male sexual dysfunction and differs from current drug therapies by working through a brain-

mediated mechanism that produces releases of serotonin and dopamine. RX-10100 is expected to enter 

Phase I clinical trials in 2006.

(cid:190) Letter from the Chairman 

Dear Fellow Stockholders: 

2005 was an exciting year of progress, opportunity and growth for Rexahn.  

I take tremendous pride in what we accomplished last year, as we moved several 

steps  closer  toward  fulfilling  our  mission  to  develop  and  market  therapeutics  that 

address unmet medical needs, especially in the areas of cancer and diseases of 

the central nervous system. 

Most  notably,  in  February  2005,  Rexahn  received  orphan  drug  designation  from  the  Food  and  Drug 

Administration  for  RX-0201,  one  of  our  leading  product  candidates.    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. 

A core element of our product development strategy is to leverage the advantages of the orphan drug 

program. 

In addition,  we  were successful in raising a total of  $13.5 million.  This funding allowed us to extend the 

scope of our research by licensing certain intellectual properties of Revaax Pharmaceuticals, a company 

focused on developing drugs for the central nervous system (CNS).  Through this license, Rexahn gained 

access  to  the  CNS  market,  which  generated  $62.4  billion  in  2005  for  the  pharmaceutical  industry 

worldwide. 

But perhaps the biggest development of the year took place in May 2005 when we completed a merger 

transaction  with  Corporate  Roadshow.Com  Inc.,  a  publicly  held  company  based  in  New  York,  and 

became a publicly traded company on the OTC Bulletin Board. As a public company, we hope to bring 

in  new  investors  and  further  strengthen  the  company’s  financial  position,  allowing  us  to  accelerate  our 

drug development and explore additional acquisition opportunities.  

As a result of our efforts last year, 2006 is poised to be our most fruitful year to date. 

RX-0201,  one  of  our  leading  oncology  candidates,  will  soon  conclude  Phase  I  clinical  trials  at 

Georgetown  University  and  the  University  of  Alabama.    RX-0201  is  a  first-in-class  signal  inhibitor  that 

directly blocks the production of Akt, a protein kinase that plays a key role in cancer progression.

So far, Phase I results have been favorable.  RX-0201 is showing a limited side effect profile with fatigue, 

not  hematological  toxicities  induced  by  other  major  cancer  drugs,  as  the  only  demonstrated  serious 

toxicity in patients.  RX-0201 is scheduled to enter Phase II in the second half of this year.  

RX-10100, the Company’s leading neuroscience compound, is also on track to enter Phase I clinical trials 

for anxiety and depression later this year.  Globally, drugs for anxiety and depression yield over $30 billion 

each year.  Many of the patents on major anxiety and depression drugs have expired or are set to expire 

soon.    I  am  very  encouraged  about  the  potential  of  RX-10100  to  fill  the  resulting  void.    Unlike  currently 

marketed drugs for anxiety and depression, RX-10100 is a serotonin and dopamine enhancer. Preclinical 

studies also indicate that RX-10100 is without many of the side effects associated with major anxiety and 

depression drugs, such as motor impairment and sexual dysfunction.   

In fact, RX-10100 has demonstrated an ability to regulate certain male sexual dysfunctions. As a result, in 

coming  months  we  will  announce  plans  to  extend  research  and  development  into  the  area  of  male 

sexual  dysfunction.    This  was  an  opportunistic  discovery  for  us  and  we  are  moving  forward  with 

development programs for RX-10100 in both sexual dysfunction and anxiety and depression. 

Finally,  far  from  our  beginnings  in  discovery  research  five  years  ago,  Rexahn  is  growing  to  include  the 

significant functions needed to progress our pipeline, such as clinical development, communications and 

marketing,  strategy,  and  business  development.    Over  the  next  year,  we  will  continue  to  grow  our  staff 

with scientific and business expertise.  With an ambitious and capable staff, we hope to focus on multiple 

drug candidates and move quickly through the clinical trial and drug development process.  

2005 was a great year for Rexahn, yet I expect 2006 to be even better.   We have an ambitious agenda 

for the year ahead, but with our talented staff and your continued support, we will undoubtedly excel. 

Thank you very much, 

Dr. Chang Ahn, 

Chairman and CEO

PART I 

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

Pharmaceuticals, Inc. 

We are a clinical stage biopharmaceutical company focused on the development of therapies for 
the treatment of cancer and diseases of the central nervous system, or CNS.  We have one drug candidate 
that is expected to enter a Phase II clinical trial later this year, two drug candidates entering into Phase I 
trials and three other drug candidates in pre-clinical development.  We intend to leverage our drug-
discovery technologies, scientific expertise and developmental know-how to develop and commercialize 
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. 

Our focus in the CNS area is on products that act on both serotonin and dopamine, which are 

major neurotransmitters controlling anxiety and depression.  RX-10100, our lead CNS product is being 
positioned as a potential treatment for anxiety and depression.  Its active ingredient has been in medical 
use for more than two decades and its safety has been well established. In animal studies, it has shown its 
efficacy against anxiety and depression in a far lower concentration than is currently being used in 
currently prescribed formulations.  This background gives RX-10100 a stronger safety record than an 
entirely new drug candidate, alleviating some of the burden of clinical trials and future risk of side effects. 
While all existing anxiety and depression drugs, mostly selective seretonin reuptake inhibitors (SSRIs), 
have been developed to work on serotonin, RX-10100 is believed to modulate both serotonin and 
dopamine at the same time.  This means that RX-10100 has the potential to be a more efficient treatment 
of both anxiety and depression, since many patients suffer from both at the same time.  In addition to 
anxiety and depression, we are evaluating the benefits of RX-10100 for the treatment of sexual 
dysfunction.  This potential application of RX-10100 arises from the observation that SSRIs with short 
half-lives have been studied for the treatment of male sexual dysfunction.  Given that RX-10100 has 
demonstrated similar effects on serotonin release as SSRIs and with a short half-life, we believe it has 
high potential for efficacy in the treatment of 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, our wholly owned subsidiary, 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 two therapeutic areas that affect the lives of many 

people—cancer and 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. 

According to the American Cancer Society's Cancer Facts & Figures 2006, cancer is the second 

leading cause of death among Americans and is responsible for one of every four deaths in the United 
States.  In 2006, 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 non-melanoma skin cancer expected to be diagnosed in 2006. 

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. 

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. 

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, 

NY3 - 405381.15 

1 

 
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, nonetheless, a considerable number of unmet needs remain in the 
treatment of cancer. 

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

•  Decreased relapse for early-stage patients:  Early-stage disease can often be effectively 

treated with surgery and radiotherapy.  While many early-stage patients will enter remission, 
the rate of relapse is high, as small numbers of tumor cells remain despite standard surgical 
and radiation therapies.  Upon recurrence, 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 cytotoxic drugs are associated with a high level of toxicity, 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 survival, is of prime importance, and such drug toxicities can 
often reduce quality of life more than the tumor itself.   

Current CNS Treatments 

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.  RX-10100, as a dual action drug, has a 
potential to address the new market. 

NY3 - 405381.15 

2 

 
RX-10100 has also shown potential in the functional therapy for male sexual dysfunction (i.e., 

erectile dysfunction and premature ejaculation).  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.  RX-10100 is not a PDE 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 CNS Therapies 

The current treatments for anxiety and depression that are offered by the SSRIs have offered 

significant improvement over the tricylic antidepressants and monamine oxidase inhibitors, both of which 
have serious side effects profiles.  Nonetheless, there remain opportunities to improve treatment in 
regards to onset and side effects.   

•  Decreased side-effect profile:  Side effects associated with current SSRI anxiolytics and 
antidepressants include nausea, sexual dysfunction, insomnia and weight gain.  The 
occurrence of one or more of these side effects in patients is the primary reason that patients 
discontinue use of these treatments. 

•  Early 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 in anxiety and 
depression.  All current medications require a few weeks for 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 
address both disorders.  Newer drugs should be able to address both symptoms of anxiety and 
depression without the unwanted side effects. 

•  Treatment of sexual dysfunction:  There are few options available for treatment of sexual 
dysfunction.  While current drugs for the treatment of erectile dysfunction improve the 
quality of lives of many people, they also exhibit side effects.  Also as of March 2006, we 
believe that there are no drugs approved for treatment of premature ejaculation, which is 
more prevalent and under-reported than erectile dysfunction.   

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 alarming 

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 

3 

NY3 - 405381.15 

 
favorable environment for formulary access and reimbursement for effective products that 
treat multiple disorders. 

•  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, RX-10100, 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; thus safety of the product is already established. 

Our therapeutic areas focus on large markets with significant unmet needs.  Business Insights' 
CNS Market Outlook to 2010 valued the anti-depressant market at close to $18 billion in 2004 with an 
annual growth rate of 3.4%.  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; 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 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 

NY3 - 405381.15 

4 

 
pharmaceutical companies that have large established sales organizations; however, to date, we have not 
entered into such agreements with any large pharmaceutical companies. 

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

Under the Orphan Drug Act, the FDA may expedite approval of new drugs that treat diseases 

affecting less than 200,000 patients each year.  This category of diseases is called an "orphan indication."  
Incentives in the Orphan Drug Act include a faster time-to-market of the drug (with FDA approval 
possible after Phase II trials instead of Phase III trials) and seven years of drug marketing exclusivity for 
the sponsor.  In addition, the FDA sometimes provides orphan research grants to aid in the costs of 
developing an orphan drug.  Once the drug candidate has received orphan drug approval, the sponsor may 
conduct larger, more extensive clinical trials seeking approval for other, more widespread diseases.  We 
plan to develop drug candidates initially for orphan category cancers in order to reduce the time-to-market 
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.  The following description of our pipeline drug candidates is based on 
pre-clinical trials and studies. 

NY3 - 405381.15 

5 

 
RX-0201:  Akt Inhibitor 

Akt is a protein kinase that plays a key role in cancer progression by stimulating cell 
proliferation, promoting angiogenesis and inhibiting apoptosis.  Akt is over-activated in a significant 
number of human cancers (e.g., breast, colorectal, gastric, head and neck, ovarian, pancreatic, prostate 
and thyroid cancers and melanoma).  Over-expression of Akt mutants in many cell types also promotes 
cellular transformation by promoting proliferation and enhancing survival.  We believe that Akt's 
transformation ability, as well as its ability to promote cancer cell survival, make it an attractive signal 
protein for our drug candidates to target in the treatment of cancer. 

We have targeted regulation of Akt-1 activity as an effective way to control proliferation and 

survival of cancer cells.  One approach to regulating Akt-1 is to use antisense oligonucleotides, or ASOs, 
to modify and regulate the gene that controls the expression and production of Akt-1.  ASOs are 
chemically modified, single-strand DNA molecules designed to bind unique sequences within targeted 
messenger RNA, or mRNA, a specialized information-packed RNA molecule which translates the cell 
DNA's genetic message into production of a specific protein.  By binding with the mRNA, ASOs block 
delivery of the genetic message, preventing translation and thereby halting disease-associated protein 
production. 

Our RX-0201 drug candidate is an ASO that is an inhibitor of Akt-1 mRNA.  RX-0201 is able to 
induce marked reduction in Akt-1 mRNA and protein expressions in cells from human carcinomas.  RX-
0201 strongly inhibits proliferation of various types of human cancer cells and growth of human tumors 
in mice.  We believe that RX-0201 is an excellent candidate for orphan cancers, while at the same time 
covering a broad spectrum of human cancers.  RX-0201 currently holds orphan designations by the FDA 
for five orphan cancers (i.e., renal cell carcinoma, pancreatic cancer, stomach cancer, brain cancer and 
ovarian cancer). 

Phase I clinical trials of RX-0201 have been ongoing at the Lombardi Comprehensive Cancer 

Center of Georgetown Medical Center in Washington, D.C. since September 2004 and at the University 
of Alabama at Birmingham since August 2005.  The Phase I clinical trial of RX-0201 will characterize 
the safety and pharmacokinetics profile, determine dose levels and describe any anti-tumor activity 
observed.  We currently estimate that the Phase I clinical trial will be completed in the second quarter of 
2006; however, completion of the Phase I clinical trial will depend on the number of subject test doses 
required to determine the maximum tolerated dose.  If more doses are needed than we originally 
estimated, then the completion of the Phase I clinical trial may be delayed.  The clinical trial will involve 
up to 40 participants.   

RX-0047:  HIF Transcription Factor Inhibitor 

Tumors cannot grow without blood vessels that supply cancer cells with oxygen and nutrients.  

HIF-1 transcription factor is a major regulating mechanism of cancer cell growth, invasion and 
angiogenesis.  HIF is over-activated in a broad range of human cancers, such as brain, breast, cervix, 
colon, kidney, liver, lung, ovarian, pancreatic, prostate, skin and stomach cancers.  HIF-1 alpha over-
expression is associated with cell proliferation and disease progression, as well as resistance to radiation 
therapy.  As a result, we believe that HIF-1 alpha is a potentially important signal transduction 
mechanism for our drug candidates to target in the treatment of cancer. 

Our RX-0047 drug candidate is an ASO that is an extremely potent inhibitor of HIF-1 alpha.  RX-

0047 directly inhibits HIF-1 alpha by reducing expressions of its mRNA and protein, resulting in the 
arrest of tumor growth and tumor metastasis, while reversing radiation resistance and inducing apoptosis.  
RX-0047 also inhibits proliferation of various types of human cancer cells.  While it will be developed 

NY3 - 405381.15 

6 

 
initially as an orphan drug, RX-0047 may also be developed to target a broad spectrum of human cancers, 
which will significantly expand its potential market. 

RX-0047 is in the pre-clinical development stage and a pre-clinical toxicology study is planned in 

the third quarter of 2006.  Phase I clinical trials of RX-0047 are expected to begin in 2007. 

RX-5902:  G2/M-Specific Cell Cycle Inhibitor 

RX-5902, a piperazine analogue, is a G2/M-specific cell cycle inhibitor.  In preclinical studies, it 

strongly induced apoptosis (cell death) and inhibited proliferation of various human cancer cells at 
nanomolar concentrations.  We expect RX-5902 to enter pre-clinical toxicology studies in the third 
quarter of 2006 and enter into Phase I clinical trials in late 2006 or early 2007.  RX-5902 may be 
developed both in intravenous and oral forms. 

RX-10100:  Dual Action Anti-anxiety and Antidepression Agent. 

RX-10100 acts on the paths of serotonin and dopamine, which are major neurotransmitters 
controlling anxiety and depression.  RX-10100 is expected to be superior to current SSRIs in efficacy and 
adverse reactions.  As a repositioned product originally used in an adjunct of antibiotics, RX-10100 has 
established its safety in more than two decades of use.  The proven safety of RX-10100 is key to our 
strategy for the development of this drug compound as a potential drug candidate for the treatment of 
anxiety and depression.  It is also expected to treat male sexual dysfunction such as erectile dysfunction 
and premature ejaculation. We are preparing to initiate a Phase I clinical trial of RX-10100 during 2006. 

Nucleic Acid Analogs as Antimetabolites and Quinazoline Analogs as AP-1/Akt Inhibitors 

Nucleic acid analogs, such as RX-3117, and quinazoline analogs, such as RX-0183 and RX-1792, 

are still in pre-clinical development, but development of these  candidates has been delayed due to our 
focus on development of our other drug candidates that address unmet medical needs within the oncology 
and CNS markets.   

Competition 

Our principal drug candidates under development are expected to address unmet medical needs 

within the oncology and CNS 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 or 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 and diseases of the central nervous system.  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.   

NY3 - 405381.15 

7 

 
Our competitors engaged in developing treatments for cancer and CNS 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 and CNS, 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 oncology market, we cannot assure you that we will compete 
successfully against these additional competitors. 

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. 

NY3 - 405381.15 

8 

 
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 affect 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.   

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. 

Research and Development  

Our research and development has focused on signal transduction inhibitors, which are drugs that 

target the communication system of cancer cells, and products affecting the central nervous system that 
act on the paths of serotonin and dopamine, major neurotransmitters controlling anxiety and depression as 

NY3 - 405381.15 

9 

 
well as potentially affecting sexual dysfunction.  Our drug discovery program in the cancer area focuses 
on key cellular signaling proteins involved in receiving and promoting growth and survival information, 
enhancing gene activity, controlling cell division, and inducing angiogenesis.  Our integrated technology 
platforms serve to maximize efficiency in discovering and validating signaling targets while 
simultaneously screening and identifying lead tumor-targeted compounds.  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. 

Manufacturing 

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

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.  See "Collaboration Arrangements" and "Certain Relationships and Related Transactions" in 
Item 12 of this Annual Report 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 
Related Transactions" in Item 12 of this Annual Report.  A brief description of some of these 
relationships is below: 

The University of Maryland("UMD").  On March 15, 2005, we entered into a Maryland 
Industrial Partnership agreement with the Biotechnology Institute of UMD to collaborate with and 
sponsor UMD's research in the area of ligand screening for novel anticancer therapeutics.  
Intellectual property made or developed under this agreement is jointly owned by us and UMD. 

Ewha Womans University ("Ewha").  On March 1, 2004, we entered into an agreement with 
Ewha to collaborate with and sponsor Ewha's research in the area of carbocyclic nucleoside, 
which relates to our anticancer drug discovery efforts.  Intellectual property made or developed in 
the course of this agreement is or will be owned by us. 

Georgetown University.  We entered into a clinical development agreement with Georgetown 
University with an effective period from April 5, 2004 through April 5, 2006.  Under the terms of 
this agreement, Georgetown University must provide us with case reports no later than 30 days 
after the termination date of this agreement or the date upon which we reasonably request delivery 
of such case reports.   

NY3 - 405381.15 

10 

 
Korea Research Institute of Chemical Technology ("KRICT").  On June 1, 2005, we entered 
into a joint research agreement with KRICT with respect to research regarding protein kinases in 
human cancer diseases.  Intellectual property made or developed under this agreement is jointly 
owned by us and KRICT. 

The University of Alabama at Birmingham.  On August 30, 2005, we entered into an 
agreement for the University of Alabama at Birmingham to carry out Phase I clinical trials of RX-
0201.  The agreement term expires on February 15, 2007.   

University of Massachusetts.  On August 1, 2005, we entered into an agreement with the 
University of Massachusetts Medical School ("UMass") to test proprietary drugs in pre-clinical 
behavioral assays of anxiety and cognition.  The agreement term expires on August 1, 2006. 

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 August 2020 and 
could extend to August 2024.  This agreement provides for an initial license fee and milestone 
payments based on the initiation of pivotal trials for disease treatment indication for licensed 
products.  Furthermore, we will pay Revaax a specified fee for each licensed product under the 
agreement upon receipt of marketing approval for the licensed product.  Notwithstanding the 
milestone payment arrangement described above, we are not obligated to make any milestone 
payment with respect to milestone events for which we receive sublicense revenues and are 
obligated to pay Revaax a percentage of such sublicense revenues, as well royalties for sales of 
licensed products based on net sales of the licensed products.  For a more detailed description, 
please refer to the agreement, which is filed as an Exhibit to this Annual Report.   

Formatech, Inc. ("Formatech").  On August 17, 2004 we entered into an agreement with 
Formatech to monitor and perform stability studies on our drug candidate, RX-0201. 

Employees 

We currently have 18 employees, all of whom are based at our Rockville, Maryland office.  Our 

employees are not covered by any collective bargaining agreement and we have never experienced a work 
stoppage.  We believe our relationships with our employees are satisfactory.

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 $3 million on clinical development for 
Phase II clinical trials of RX-0201 and Phase I clinical trials for RX-5902 and RX-10100.  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 
RX-0201, RX-10100 and RX-5902.  

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 RX-0047 and 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 $20 million through the second quarter 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, which will 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, 2005 and 2004 was $14,204,323 and $7,854,783, respectively.  For the years ended 
December 31, 2005 and 2004, we had net losses of $6,349,540 and $3,273,442, 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:  

NY3 - 405381.15

• 

• 

• 

• 

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

efforts to seek regulatory approvals for our drug candidates; 

implementing additional internal systems and infrastructure; 

licensing in additional technologies to develop; and 

•  hiring additional personnel. 

We also expect to continue to experience negative cash flow for the foreseeable future as we fund 

our operating losses and capital expenditures.  As a result, we will need to generate significant revenues 
in order to achieve profitability.   

We have a limited operating history.  

We are a development-stage company with four 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. 

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 four drug candidates, RX-0201 
and RX-0047, are ASO compounds.  To date, the FDA has not approved any NDAs for any ASO 
compounds.  In addition, both RX-0201 and RX-0047 are of a drug class (Akt inhibitor, in the case of 
RX-0201, and HIF inhibitor, in the case of RX-0047) that has not been approved by the FDA to date.  

NY3 - 405381.15 

13 

 
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 2006, we expect to have one 
oncology drug candidate entering Phase II clinical trials, one neuroscience drug candidate entering Phase 
I clinical trials and one oncology drug candidate in Phase I clinical trials.   

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

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

•  unforeseen safety issues; 

•  determination of dosing issues; 

• 

• 

• 

• 

• 

lack of effectiveness during clinical trials; 

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

slower than expected rates of patient recruitment; 

inability to monitor patients adequately during or after treatment;  

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

• 

lack of sufficient funding to finance the clinical trials. 

In addition, we or the FDA may suspend clinical trials at any time if it appears that we are 

exposing participants to unacceptable health risks or if the FDA finds deficiencies in our IND 
submissions or the conduct of these trials.    

NY3 - 405381.15 

14 

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

Even if our clinical trials are completed as planned, we cannot be certain that our results will 

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

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

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

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

• 

awareness of the drug's availability and benefits; 

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

and effectiveness of our drugs; 

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

• 

• 

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

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

• 

the price at which we sell our products. 

Because we expect sales of our current drug candidates, if approved, to generate substantially all 

of our product revenues for the foreseeable future, the failure of any of these drugs to find market 
acceptance would harm our business and could require us to seek additional financing. 

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

We depend upon independent investigators and collaborators, such as universities and medical 
institutions, to conduct our pre-clinical and clinical trials.  For example, the Phase I clinical trials of RX-
0201 are being conducted at the Lombardi Comprehensive Cancer Center of Georgetown Medical Center 
with the assistance of Amarex, LLC, a pharmaceutical clinical research service provider who will be 
responsible for creating the reports that will be submitted to the FDA.  We also relied on TherImmune 
Research Corporation (currently Gene Logic Laboratories, Inc.), a discovery and pre-clinical service 
provider, to summarize RX-0201'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 

NY3 - 405381.15 

15 

 
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.  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.  and Avecia Biotechnology Inc. to 
manufacture, supply, store and distribute supplies of our drug candidates for our clinical trials.  If any of 
our drug candidates receive FDA approval, we will rely on these or other third-party contractors to 
manufacture our drugs.  Our reliance on third-party manufacturers exposes us to the following potential 
risks: 

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

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

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

•  Our contract manufacturers may not perform as agreed or may not remain in the contract 

manufacturing business for the time required to supply our clinical trials or to successfully 
produce, store and distribute our products. 

•  Drug manufacturers are subject to ongoing periodic unannounced inspection by the FDA, the 

Drug Enforcement Agency, or 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 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 

NY3 - 405381.15 

16 

 
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 Antigenics Inc., Genta Incorporated, Imclone 
Systems Incorporated, Human Genome Sciences, Inc., Kosan Biosciences Incorporated and Medimmune, 
Inc.  In addition, many of these competitors, either alone or together with their collaborative partners, 
operate larger research and development programs or have substantially greater financial resources than 
we do, as well as more experience in: 

•  developing drugs; 

•  undertaking pre-clinical testing and human clinical trials;  

•  obtaining FDA and other regulatory approvals of drugs; 

• 

• 

formulating and manufacturing drugs; and 

launching, marketing and selling drugs. 

Large pharmaceutical companies such as Bristol-Myers, Squibb, Eli-Lilly, Novartis and Glaxo-

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

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 
17 

NY3 - 405381.15 

 
U.S. and PCT patent applications for anti-Akt compounds, including RX-0201, anti-HIF compounds, 
including RX-0047.  We have also filed three U.S. provisional patent applications for new anti-cancer 
quinazoline compounds, new anti-cancer nucleoside products and a drug target, cenexin, a polo-box 
binding protein.  In December 2004, we also filed two Korean patent applications for new anti-cancer 
piperazine compounds.  Through our licensing agreement with Revaax, we hold exclusive rights to five 
patents and 14 patent applications, with respect to certain chemical structures related to antibiotics, but 
without antibiotic efficacy. 

However, we cannot predict:  

• 

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

• 

if and when patents will issue; 

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

licensed patents and patent applications; or  

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

whether we win or lose. 

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

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

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

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

•  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. 
18 

NY3 - 405381.15 

 
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 

those agreements, 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, which would significantly harm our business and future prospects. 

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

In addition to our own internally developed drug candidates, we proactively seek opportunities to 

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

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

Attracting and retaining qualified personnel will be critical to our future success.  We compete for 

qualified individuals with numerous biopharmaceutical companies, universities and other research 
institutions.  Competition for such individuals is intense, and we cannot assure you that we will be 
successful.   

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 

NY3 - 405381.15 

19 

 
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, 2005 and 2004 was $14,204,323 and 
$7,854,783, respectively.  For the years ended December 31, 2005 and 2004, we had net losses of 
$6,349,540 and $3,273,442, respectively, primarily as a result of expenses incurred through a 
combination of research and development activities related to the various technologies under our control 
and expenses supporting those activities.  Until we receive approval from the FDA and other regulatory 
authorities for our drug candidates, we cannot sell our drugs and will not have product revenues.   

The market price of our common stock may fluctuate significantly.   

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

which are beyond our control, such as: 

• 

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

•  developments concerning intellectual property rights and regulatory approvals; 

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

• 

changes in earnings estimates or recommendations by securities analysts; and 

•  developments in the biotechnology industry. 

Further, the stock market, in general, and the market for biotechnology companies, in particular, 
have experienced extreme price and volume fluctuations.  Continued market fluctuations could result in 
extreme volatility in the price of our common stock, which could cause a decline in the value of our 
common stock.  You should also be aware that price volatility might be worse if the trading volume of 
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 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 
464,156 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, or "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 110 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 5.  Market for Common Equity and Related Stockholder Matters. 

As of March 27, 2006, 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 27, 2006, we have 46,415,632 shares of common stock outstanding and 
approximately 110 stockholders of record of common stock.  As of March 27, 2006, no shares of 
preferred stock are outstanding. 

Our common stock is traded on the Over the Counter Bulletin Board (the "OTC-BB") under the

Recent Sales of Unregistered Securities 

In connection with the Merger described under Item 1 of this Annual Report, we issued an 
aggregate of 38,140,830 shares of common stock to the former shareholders of Rexahn, Corp.  The 
common stock issued in the Merger was exempt from the registration requirements of the Securities Act 
of 1933, as amended (the "Securities Act"), pursuant to Section 4(2) of the Securities Act, Regulation D 
under the Securities Act and/or Regulation S under the Securities Act.  These shares of 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.  We did not receive any cash proceeds from the issuance of these 
securities. 

Following the Merger, we issued 500,000 "restricted" shares of common stock to Frank Ferraro, 
the  CPRD's  sole  director  and  officer,  pursuant  to  a  Settlement  Agreement.    The  issuance  of  shares  of 
common stock to Mr. Ferraro did not involve any public offering and was exempt from the registration 
requirements  under  the  Securities  Act  pursuant  to  Section 4(2)  thereof.    We  did  not  receive  any  cash 
proceeds from the issuance of these securities. 

On  August  8,  2005,  we  completed  a  private  placement  of  4,175,000  shares  of  common  stock, 
$.0001 par value per share, at $2.00 per share for aggregate gross proceeds of $8.35 million pursuant to 
the  Subscription  Agreements  dated  August  8,  2005.    The  offers  and  sales  occurred  outside  the  United 
States to persons other than U.S. persons in offshore transactions meeting the requirements of Regulation 
S under the Securities Act.  After payment of certain expenses by us, we received approximately $8.31 
million in net proceeds upon closing of the private placement of the common stock.  The proceeds will be 
used  to  fund  clinical  trials  of  our  drug  candidates  and  other  general  corporate  purposes.    Shares  of  the 
common stock have not been registered under the Securities Act and may not be offered or sold in the 
Unites  States  absent  registration  under  the  Securities  Act  or  an  applicable  exemption  from  registration 
requirements under the Securities Act.

On  August  8,  2005,  we  also  completed  a  private  placement  of  $1.3  million  aggregate  principal 
amount  of  our  convertible  notes  (the  "Convertible  Notes")  in  offers  and  sales  that  occurred  outside  the 
United  States  to  persons  other  than  U.S.  persons  in  offshore  transactions  meeting  the  requirements  of 
Regulation S under the Securities Act.  The holders of the Convertible Notes are entitled any time after 
September 19, 2005 until August 8, 2008 (the "Maturity Date"), 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 initial conversion price of $2.00 
per share of common stock is subject to adjustment upon the occurrence of certain events, including the 
issuance of any additional capital stock after August 8, 2005, without consideration or for a consideration 
per  share  less  than  the  current  market  price  per  share  of  additional  capital  stock  as  of  the  time  of  such 
issuance.    On  December  2,  2005,  the  holders  of  convertible  notes,  representing  $1,300,000  aggregate 
principal  amount,  exercised  their  option  to  convert  the  entire  principal  amount  of  the  notes  into  the 
Company's  common  stock.    Based  on  a  $2.00  per  share  conversion  price,  the  holders  received  an 
aggregate of 650,000 shares.

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 
and their basis of application is consistent with that of the previous year. 

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 

NY3 - 405381.15 

25 

 
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 

The Company uses 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" and, as permitted by SFAS No. 123 "Accounting for Stock-Based Compensation", provides 
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 is 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 is amortized over the vesting period using an accelerated graded 
method in accordance with Financial Accounting Standards Board ("FASB") Interpretation No. 28, 
"Accounting for Stock Appreciation Rights and Other Variable Stock Option or Award Plans." 

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

accordance with SFAS No. 123. 

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. 
In addition, option valuation models require the input of highly subjective assumptions, and changes in 
such subjective assumptions can materially affect the fair value estimate of employee stock options.  

In December 2004, the FASB issued SFAS No. 123R, "Share-Based Payment".  This 

pronouncement amends SFAS No. 123 and supersedes APB 25.  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 amounts in the statement of operations.   The implementation of this statement will be 
effective beginning with the Company's first quarter of fiscal 2006, and will be adopted using the 
modified prospective method. 

Recently Issued Accounting Standards 

In December 2004, the FASB issued SFAS No. 153, "Exchanges of Non monetary Assets, an 

amendment of APB Opinion No. 29". SFAS No. 153 replaces the exception from fair value measurement 
in APB Opinion No. 29 for non-monetary exchanges of similar productive assets with a general exception 
from fair value measurement for exchanges of non-monetary assets that do not have commercial 
substance. A non-monetary exchange has commercial substance if the future cash flows of the entity are 
expected to change significantly as a result of the exchange. SFAS No. 153 is to be applied prospectively, 
and is effective for non-monetary asset exchanges occurring in fiscal periods after the December 2004 
issuance of SFAS No. 153. The adoption of SFAS No. 153 in 2005 has not been significant to the 
Company's overall results of operations or financial position. 

In December 2004, the FASB issued SFAS No. 123 (revised 2004), "Share Based Payment" 

("SFAS No. 123R"). SFAS No. 123R requires the Company to measure the cost of employee services 
received in exchange for an award of equity instruments based on the grant date fair value of the award. 
The cost of the employee services is recognized as compensation cost over the period that an employee 
provides service in exchange for the award. SFAS No. 123R will be effective January 1, 2006 for the 
Company and will be adopted using the modified prospective method.  The Company expects that the 
adoption of SFAS 123R may have a material impact on its results of operations subsequent to adoption.    

NY3 - 405381.15 

26 

 
The disclosures in Note 8 to the financial statements in Item 7 of this Annual Report provides detail as to 
the Company's financial performance as if the Company had applied the fair value based method and 
recognition provisions of SFAS No. 123R to stock based employee compensation to the current reporting 
periods. 

In March 2005, the FASB issued FASB Staff Position ("FSP") No. 46(R)-5, "Implicit Variable 

Interests under FASB Interpretation No. ("FIN") 46 (revised December 2003), Consolidation of Variable 
Interest Entities" ("FSP FIN 46R-5"). FSP FIN 46R-5 provides guidance for a reporting enterprise on 
whether it holds an implicit variable interest in Variable Interest Entities ("VIEs") or potential VIEs when 
specific conditions exist. This FSP is effective in the first period beginning after March 3, 2005 in 
accordance with the transition provisions of FIN 46 (revised December 2003), "Consolidation of Variable 
Interest Entities - an Interpretation of Accounting Research Bulletin No. 51" ("FIN 46R"). The adoption 
of FSP FIN 46R-5 in 2005 did not have an impact on the Company's results of operations and financial 
position.  

In March 2005, the FASB issued Interpretation No. 47, "Accounting for Conditional Asset 

Retirement Obligations" ("FIN 47"), which will result in (1) more consistent recognition of liabilities 
relating to asset retirement obligations, (2) more information about expected future cash outflows 
associated with those obligations, and (3) more information about investments in long-lived assets 
because additional asset retirement costs will be recognized as part of the carrying amounts of the assets. 
FIN 47 clarifies that the term "conditional asset retirement obligation" as used in SFAS No. 143, 
"Accounting for Asset Retirement Obligations", refers to a legal obligation to perform an asset retirement 
activity in which the timing and/or method of settlement are conditional on a future event that may or 
may not be within the control of the entity. The obligation to perform the asset retirement activity is 
unconditional even though uncertainty exists about the timing and/or method of settlement. Uncertainty 
about the timing and/or method of settlement of a conditional asset retirement obligation should be 
factored into the measurement of the liability when sufficient information exists. FIN 47 also clarifies 
when an entity would have sufficient information to reasonably estimate the fair value of an asset 
retirement obligation. FIN 47 is effective no later than the end of fiscal years ending after December 15, 
2005. The adoption of FIN 47 in 2005 did not have a material impact on the financial position or results 
of operations of the Company. 

In May 2005, the FASB issued SFAS No. 154, "Accounting Changes and Error Corrections", 

which replaces APB Opinion No. 20, "Accounting Changes", and SFAS No. 3, "Reporting Accounting 
Changes in Interim Financial Statements - An Amendment of APB Opinion No. 28". SFAS No. 154 
provides guidance on the accounting for and reporting of changes in accounting principles and error 
corrections. SFAS No. 154 requires retrospective application to prior period financial statements of 
voluntary changes in accounting principle and changes required by new accounting standards when the 
standard does not include specific transition provisions, unless it is impracticable to do so. SFAS No. 154 
also requires certain disclosures for restatements due to correction of an error. SFAS No. 154 is effective 
for accounting changes and corrections of errors made in fiscal years beginning after December 15, 2005, 
and is required to be adopted by the Company as of January 1, 2006. The impact that the adoption of 
SFAS No. 154 will have on the Company's results of operations and financial condition will depend on 
the nature of future accounting changes adopted by the Company and the nature of transitional guidance 
provided in future accounting pronouncements.

Results of Operations 

Comparison of the Year Ended December 31, 2005 and the Year Ended December 31, 2004 

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 RX-0201 drug candidate 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 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 of fiscal 2005, 2004 and 2003 and the remaining $1,275,000 is reflected 
as deferred revenue on the balance sheet as of December 31, 2005.  We adopted Staff Accounting 
Bulletin 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 
RX-0201.   

In fiscal 2005, we recorded $190,610 of interest income from the investment of our cash and cash 
equivalents and other short-term investments, compared to $57,463 recorded in fiscal 2004.  The increase 
of $133,147, or 231.7%, was primarily due to interest income from the investment of the proceeds of 
financing activities in 2005, including private placements of long-term debt and common stock as 
described under "Recent Sales of Unregistered Securities" in Item 5 of this Annual Report. 

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 $1,237,273, or 93.7%, from $1,319,892 in fiscal 

2004 to $2,557,165 in fiscal 2005.  The increase was due primarily to an increase in professional fees and 
expenses incurred in connection with our reverse merger transaction completed on May 13, 2005, 
including legal, accounting and public relations fees and expenses, and increased compliance costs 
associated with being a public company. 

Research and Development Expenses 

Research and development expenses consist primarily of salaries and related personnel costs, fees 

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

Research and development expenses decreased $263,629, or 14.7%, from $1,788,025 in fiscal 
2004 to $1,524,396 in fiscal 2005.  The decrease was due primarily to the fact that the clinical trials of 
RX-0201, one of our drug candidates, have been ongoing without additional payment during fiscal 2005.  
We expect that research and development expenses will increase as our drug candidates move into the 
clinical trials phases of development. 

NY3 - 405381.15

Stock Option Compensation Expense 

Our results include non-cash compensation expense as a result of stock option grants.  We 
account 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 is 
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. 

See Note 8 to the Financial Statements in Item 7 of this Annual Report for further information on 

our stock option compensation expense.

Patent Fees 

Our patent fees increased $168,877, or 1,732.4%, from $9,748 in fiscal 2004 to $178,625 in fiscal 
2005.  The increase was due primarily to an increase in the number of patent filings made during the 2005 
period compared to fiscal 2004. 

Interest Expense 

Our interest expense increased $192,135, or 4104.5%, from $4,681 in fiscal 2004 to $196,816 in 

fiscal 2005.  The increase was due primarily to interest payable on the convertible notes issued in 
February 2005.  We also reflected a charge of $1,625,000 which represents the beneficial conversion 
feature of the Company's convertible notes which were issued in August 2005 and converted into 
Company common stock in December 2005. 

Depreciation 

Depreciation expense increased $43,611, or 82.6%, from $52,789 in fiscal 2004 to $96,400 in 

fiscal 2005.  The increase was due primarily to a move to a new facility in July 2004 and the related 
purchase of new laboratory equipment. 

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 four lead drug candidates, RX-0201, RX-0047, RX-5902 and RX-10100. 

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 candidate, RX-0201, is uncertain, and because RX-0047, RX-5902 and RX-10100 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.  

NY3 - 405381.15 

30 

 
 
 
RX-0201 

RX-0201 is currently our leading drug candidate and has been in a Phase I clinical trial at 
Georgetown University's Lombardi Cancer Center since September 2004 and University of Alabama at 
Birmingham since August 2005. The costs incurred for the clinical trial to date have been approximately 
$750,000. As the main purpose of this clinical trial is to establish the safety of RX-0201, the parameters 
that determine the completion of this project are a direct function of the safety profile of this compound in 
humans. As this is the first time that RX-0201 has been administered to humans, the safety profile in 
humans is unknown and therefore, the number of doses required to determine the dosage at which the 
FDA safety endpoints are met is an estimate. If more doses are required than estimated, completion of the 
Phase I clinical trials may be delayed. Therefore, the costs, timing and efforts necessary to complete this 
program also are estimates. We currently estimate that the completion of the Phase I clinical trial will 
require approximately $300,000 and anticipate its completion in the second quarter of 2006. 

RX-0047 and RX-5902 

RX-0047 and RX-5902 are all 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. To date, the costs incurred for development of 
these compounds to date have been approximately $750,000 for RX-0047, and $250,000 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 late 2006 or early 2007. 

The conduct of the clinical trial and toxicology studies described above are being accomplished in 

conjunction with third-party 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. 

RX-10100 

RX-10100 is in early pre-IND stages of development and the next scheduled event is the 
synthesis and testing of novel formulations for pre-clinical and clinical evaluations. We currently estimate 
that these studies will require approximately $300,000 and $450,000, respectively.  We are preparing to 
initiate a Phase I clinical trial of RX-10100 during 2006. 

Liquidity and Capital Resources 

Cash used in operating activities was $4,131,450 in fiscal 2005 compared to $2,880,624 in fiscal 
2004.  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 include a charge 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 consists 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.  
Fiscal 2004 operating cash flows reflect Rexahn's loss from continuing operations of $3,273,442, offset 

NY3 - 405381.15 

31 

 
 
 
 
by non-cash charges of $283,559 and a net increase in cash components of working capital of $184,259.  
Non-cash charges consisted of depreciation of $52,789 and stock option compensation expense of 
$230,770.  The increase in working capital primarily consisted of a $189,487 increase in accounts 
payable. 

Cash used in investing activities of $7,915,750 in fiscal 2005 consist of purchases of short-term 

investments of $7,821,667, in addition to capital expenditures of $94,083 for the purchase of equipment.  
Cash provided by investing activities of $1,263,194 in fiscal 2004 reflect the sale of short-term 
investments of $1,384,482, offset by capital expenditures of $121,288 for the purchase of equipment.   

Cash provided by financing activities of $1,800 in fiscal 2004 consisted of proceeds from the 

issuance of Rexahn common stock upon 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, 2005 and 2004, we experienced net losses of $6,349,540 and 
$3,273,442, respectively.  Our accumulated deficit as of December 31, 2005 and 2004 were $14,204,323 
and $7,854,783, respectively.   

We have financed our operations since inception primarily through equity and convertible debt 
financings.  During fiscal 2005, we had a net increase in cash and cash equivalents of $1,278,979.  This 
increase primarily resulted from proceeds from the issuance of convertible debt and common stock in 
fiscal 2005.  Total cash resources as of December 31, 2005 were $1,679,441 compared to $400,462 at 
December 31, 2004.  In addition, we had $8,437,184 in short-term investments at December 31, 2005.   

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

Contractual Obligations 

In April 2004, we entered into a clinical development agreement with Georgetown University 

with an effective period from April 5, 2004 through April 5, 2006.  The total estimated cost of the 
program is $223,126, based on the fees, enrolment and completion of 20 patients and is payable based on 
the progress of the treatment over the effective period of the agreement.  For the years ended December 
31, 2005 and 2004, we paid $0 and  $17,426, respectively towards the cost of this program.  In addition, 
we extended a research agreement, initially entered into on January 1, 2004, until November 10, 2005 
with Georgetown University.  For the year ended December 31, 2005, we paid $60,000 in consideration 
of the extension. 

On August 17, 2004, we entered into an agreement with Formatech, Inc. to monitor and perform 

stability studies on our drug candidate, RX-0201.  The total cost of these services is $46,700.  For the 
years ended December 31, 2005 and 2004, we paid $10,400 and $22,900, respectively, towards the cost 
of these studies.  The remainder consists of a $5,200 payment due during 2006 and $8,200 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 

NY3 - 405381.15 

32 

 
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. 

NY3 - 405381.15 

33 

 
Minimum future rental payments under this lease are as follows:

On June 1, 2005, we signed a one year research project agreement with the Korea Research 

Institute of Chemical Technology ("KRICT") relating to the development of a synthetic process for the 
lead compound of the quinozalines acting on human cancer cells.  In accordance with the agreement, the 
cost of the project is $100,000, of which $50,000 was paid during the 2005 fiscal year.  The remaining 
$50,000 is included in accounts payable at December 31, 2005. 

On August 1, 2005, we signed a one year contract with the University of Massachusetts Medical 

School ("UMASS") to test proprietary drugs in preclinical behavioral assays of anxiety and cognition.  
We agreed to provide UMASS with a grant of $76,666, which includes the full direct and indirect costs of 
the preclinical study, payable in four equal quarterly installments of $19,167.  For the year ended 
December 31, 2005, we made two quarterly payments totaling $38,334.  The remainder is due in 2006. 

On August 3, 2005, we engaged Montgomery Pacific Group ("MPG") to act as the Company's 

financial advisor for a one-year term in connection with our growth strategies, certain licensing activities 
and acquisition of certain assets. In consideration of the services, we agreed to pay MPG an advisory fee, 
consisting of an initial retainer fee and success fees subject to the successful closing of licensing 
transactions, acquisitions and private placements. An initial retainer fee of $50,000 was paid during the 
year ended December 31, 2005.  Dr. John Holaday, one of our directors, is a partner of MPG. 

Although we currently believe that our cash and cash equivalents will be sufficient to meet our 

minimum planned operating needs for the next 12 months, including the amounts payable under the 
contractual commitments described above, as our drug candidates move into the clinical trials phase of 
development, we expect to enter into additional agreements of the same type, which may require 
additional contractual commitments.  These additional commitments may have a negative impact on our 
future cash flows.   

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 
discovery efforts.  Based on our current plans and out capital resources (including the proceeds of our 
2005 financings), 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 RX-0201 and the pre-clinical studies and Phase I clinical trials for 
RX-10100.  Over the next 12 months we expect to spend a minimum of approximately $3 million on 
clinical development for Phase I and Phase II clinical trials of RX-0201 (including our commitments 

NY3 - 405381.15 

34 

 
 
 
 
 
 
 
 
 
 
described under "Contractual Commitments" of this Item 6), $2.5 million on general corporate expenses, 
and $250,000 on facilities rent.  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 pre-clinical studies and Phase I clinical trials for RX-0047 and in-vivo animal 
and pre-clinical studies and Phase I clinical trials for RX-5209, RX-10100 and other 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 $10 million through the first quarter of 2007. 

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.

(A Development Stage Company) 
Notes to Financial Statements 
December 31, 2005 and 2004 

1.  Operations and Organization 

Operations 

Rexahn  Pharmaceuticals,  Inc.  (the  "Company"  or  "Rexahn  Pharmaceuticals"),  a  Delaware 
corporation,  is  a  development  stage  biopharmaceutical  company  focused  on  the  development  of 
signal inhibitor drug therapies for the treatment of cancer and other diseases.  

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 acquiror) by Rexahn (accounting acquiror).  As a result, following the Acquisition Merger, the 
historical financial statements of Rexahn became the historical financial statements of the Company. 

Merger of Subsidiary 

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

d)  Research and Development  

Research  and  development  costs  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. 

e)  Government Grants 

Income from government grants are recorded when received. Amounts received are applied to 
the   expenses that they are intended to compensate.

f) 

Revenue Recognition 

The  Company  recognizes  revenues  from  research  and  license  agreements  as  the  contracted 
services are performed, in accordance with the terms of the agreement.  Amounts received in 
advance of recognition are included in deferred revenues. 

Interest and securities income is recognized on an accrual basis. 

g)  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.  

h) 

Fair Value of Financial Instruments 

The carrying amounts reported in the accompanying financial statements for current assets and 
current liabilities approximates fair value because of the short-term maturity of these financial 
instruments.  The fair value of long-term convertible debt is indeterminable due to terms of the 
instrument and the absence of a market for such instruments.   

i) 

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.

j) 

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, 2005 and 2004 because their 
effect would have been antidilutive:

The  Company  uses  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"  and,  as  permitted  by  SFAS  No.  123,  "Accounting  for  Stock-Based 
Compensation" ("SFAS 123"), provides 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  is 
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 is amortized over the vesting period using an accelerated 
graded  method  in  accordance  with  Financial  Accounting  Standards  Board  ("FASB") 
Interpretation  No.  28,  "Accounting  for  Stock  Appreciation  Rights  and  Other  Variable  Stock 
Option or Award Plans." 

For  all  non-employee  stock-based  compensation  the  Company  uses  the  fair  value  method  in 
accordance with SFAS No. 123 and EITF 96-18.

k) 

Stock-Based Compensation (cont'd) 

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.  In  addition,  option  valuation  models  require  the  input  of  highly  subjective 
assumptions,  and  changes  in  such  subjective  assumptions  can  materially  affect  the  fair  value 
estimate of employee stock options.  

In  December  2004,  the  FASB  issued  SFAS  No.  123R,  "Share-Based  Payment".    This 
pronouncement amends SFAS No. 123 and supersedes APB Opinion No. 25.  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 amounts in the statement of operations.   
The  implementation  of  this  statement  will  be  effective  beginning  with  the  Company's  first 
quarter of fiscal 2006, and will be adopted using the modified prospective method. 

l) 

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 cost to sell.  

m)  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.

n)  Recent Accounting Pronouncements  

In December 2004, the FASB issued SFAS No. 153, "Exchanges of Non monetary Assets, an 
amendment  of  APB  Opinion  No.  29".  SFAS  No.  153  replaces  the  exception  from  fair  value 
measurement in APB Opinion No. 29 for non-monetary exchanges of similar productive assets 
with  a  general  exception  from  fair  value  measurement  for  exchanges  of  non-monetary  assets 
that do not have commercial substance. A non-monetary exchange has commercial substance if 
the  future  cash  flows  of  the  entity  are  expected  to  change  significantly  as  a  result  of  the 
exchange. SFAS No. 153 is to be applied prospectively, and is effective for non-monetary asset 
exchanges occurring in fiscal periods after the December 2004 issuance of SFAS No. 153. The 
adoption of SFAS No. 153 in 2005 has not been significant to the Company's overall results of 
operations or financial position. 

In  December  2004,  the  FASB  issued  SFAS  No.  123  (revised  2004),  "Share  Based  Payment" 
("SFAS No. 123R"). SFAS No. 123R requires the Company to measure the cost of employee 
services received in exchange for an award of equity instruments based on the grant date fair 
value of the award. The cost of the employee services is recognized as compensation cost over 
the period that an employee provides service in exchange for the award. SFAS No. 123R will 
be  effective  January  1,  2006  for  the  Company  and  will  be  adopted  using  the  modified 
prospective  method.    The  Company  expects  that  the  adoption  of  SFAS  123R  may  have  a 
material impact on its results of operations subsequent to adoption.    The disclosures in Note 8 
provides detail as to the Company's financial performance as if the Company had applied the 
fair  value  based  method  and  recognition  provisions  of  SFAS  No.  123R  to  stock  based 
employee compensation to the current reporting periods. 

In March 2005, the FASB issued FASB Staff Position ("FSP") No. 46(R)-5, "Implicit Variable 
Interests under FASB Interpretation No. ("FIN") 46 (revised December 2003), Consolidation of 
Variable  Interest  Entities"  ("FSP  FIN  46R-5").  FSP  FIN  46R-5  provides  guidance  for  a 
reporting  enterprise  on  whether  it  holds  an  implicit  variable  interest  in  Variable  Interest 
Entities ("VIEs") or potential VIEs when specific conditions exist. This FSP is effective in the 
first period beginning after March 3, 2005 in accordance with the transition provisions of FIN 
46 (revised December 2003), "Consolidation of Variable Interest Entities - an Interpretation of 
Accounting Research Bulletin No. 51" ("FIN 46R"). The adoption of FSP FIN 46R-5 in 2005 
did not have an impact on the Company's results of operations and financial position.  

In May 2003, the FASB issued SFAS No. 150, "Accounting for Certain Financial Instruments 
With  Characteristics  of  Both  Liabilities  and  Equity".    SFAS  No.  150  requires  that  issuers 
classify  as  liabilities  the  following  three  types  of  freestanding  financial  instruments:  (1) 
mandatory  redeemable  financial  instruments,  (2)  obligations  to  repurchase  the  issuer's  equity 
shares by transferring assets; and (3) certain obligations to issue a variable number of shares.  
The Company adopted SFAS No. 150 for the year ended December 31, 2003.  The adoption of 
SFAS No. 150 did not have a material impact on the financial position or results of operations 
of the Company.

n)  Recent Accounting Pronouncements (cont'd) 

In  March  2005,  the  FASB  issued  Interpretation  No.  47,  "Accounting  for  Conditional  Asset 
Retirement  Obligations"  ("FIN  47"),  which  will  result  in  (1)  more  consistent  recognition  of 
liabilities  relating  to  asset  retirement  obligations, (2) more  information  about  expected  future 
cash outflows associated with those obligations, and (3) more information about investments in 
long-lived  assets  because  additional  asset  retirement  costs  will  be  recognized  as  part  of  the 
carrying  amounts  of  the  assets.  FIN  47  clarifies  that  the  term  "conditional  asset  retirement 
obligation" as used in SFAS No. 143, "Accounting for Asset Retirement Obligations", refers to 
a legal obligation to perform an asset retirement activity in which the timing and/or method of 
settlement are conditional on a future event that may or may not be within the control of the 
entity.  The  obligation  to  perform  the  asset  retirement  activity  is  unconditional  even  though 
uncertainty exists about the timing and/or method of settlement. Uncertainty about the timing 
and/or method of settlement of a conditional asset retirement obligation should be factored into 
the measurement of the liability when sufficient information exists. FIN 47 also clarifies when 
an  entity  would  have  sufficient  information  to  reasonably  estimate  the  fair  value  of  an  asset 
retirement  obligation.  FIN  47  is  effective  no  later  than  the  end  of  fiscal  years  ending  after 
December  15,  2005.  The  adoption  of  FIN  47  in  2005  did  not  have  a  material  impact  on  the 
financial position or results of operations of the Company. 

In May 2005, the FASB issued SFAS No. 154, "Accounting Changes and Error Corrections", 
which  replaces  APB  Opinion  No.  20,  "Accounting  Changes",  and  SFAS  No.  3,  "Reporting 
Accounting  Changes  in  Interim  Financial  Statements  -  An  Amendment  of  APB  Opinion  No. 
28".  SFAS  No.  154  provides  guidance  on  the  accounting  for  and  reporting  of  changes  in 
accounting principles and error corrections. SFAS No. 154 requires retrospective application to 
prior  period  financial  statements  of  voluntary  changes  in  accounting  principle  and  changes 
required  by  new  accounting  standards  when  the  standard  does  not  include  specific  transition 
provisions, unless it is impracticable to do so. SFAS No. 154 also requires certain disclosures 
for  restatements  due  to  correction  of  an  error.  SFAS  No.  154  is  effective  for  accounting 
changes and corrections of errors made in fiscal years beginning after December 15, 2005, and 
is required to be adopted by the Company as of January 1, 2006. The impact that the adoption 
of SFAS No. 154 will have on the Company's results of operations and financial condition will 
depend on the nature of future accounting changes adopted by the Company and the nature of 
transitional guidance provided in future accounting pronouncements.

Intangible Assets 

On  February  10,  2005,  the  Company  entered  into  a  licensing  agreement  with  Revaax 
Pharmaceuticals LLC ("Revaax"), whereby the Company received an exclusive, worldwide, royalty 
bearing  license  with  the  right  to  sub-license  Revaax's  licensed  technology  and  products.    The 
agreement  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 $339,890 as at  December 31, 2005 has been 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 liability component is being accreted over the term of 
the liability, calculated based on the Company's estimated effective market interest rate. The asset is 
amortized  on  a  straightline  basis  over  the  estimated  useful  life  of  20  years.  Pursuant  to  the 
agreement, at  December 31, 2005, four installments had been paid.  As at  December 31, 2005, the 
outstanding balance was $172,813.  Amortization expenses for 2005 amounted to $16,326.

5.  Long-Term Convertible Debt 

On  February  28,  2005,  the  Company  issued,  in  a  transaction  exempt  from  registration  under  the 
Securities Act, $3,850,000 aggregate principal amount of 6% convertible notes due on February 28, 
2008.  The  notes  are  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 and (ii) May 26, 2006 to the maturity date, February 28, 2008. The 
notes will 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  and  (ii)  the 
maturity  date.  The  conversion  price  is  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 August 8, 2005, the Company completed a private placement of $1.3 million aggregate principal 
amount of convertible notes.  The holders of these  notes are 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 note 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., 
Ltd. ("Rexgene"), a minority shareholder.  Rexgene is engaged in the development of pharmaceutical 
products in Asia and has agreed to assist the Company with the research, development and clinical 
trials necessary for registration of, the Company's drug candidate, RX-0201 in Asia.  This agreement 
provides Rexgene with exclusive rights to license, sublicense, make, have made, use, sell and import 
RX-0201  in  Asia.  A  one  time  contribution  to  the  joint  development  and  research  of  RX-0201  of 
$1,500,000  was  paid  to  the  Company  in  2003  in  accordance  with  the  agreement.    The  amount  of 
revenue from this contribution is being recognized as income over the term of the agreement which 
terminates at the later of 20 years or the term of the patent on the licensed product. The Company is 
using  20 years  as  its  basis  for  recognition  and  accordingly    $75,000  was  included  in  revenues  for 
each of the years ended December 31, 2005 and 2004.  The remaining $1,275,000 at December 31, 
2005  (2004-$1,350,000)  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 2007.

8.  Stock-Based Compensation 

On  August  5,  2003,  the  Company  established  a  stock  option  plan.    Under  the  plan,  the  Company 
grants  stock  options  to  key  employees,  directors  and  consultants  of  the  Company.    For  all  grants 
prior to September 12, 2005 and grants to employees of the Company after September 12, 2005, the 
vesting period is 30% 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.  Options authorized for issuance 
total 6,952,500 and as of December 31, 2005, 1,182,500 options are available for issuance. 

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

The  exercise  price  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 in January 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 is January 1, 2005.  The amendment was accounted for prospectively 
and  resulted  in  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 non-employees accounted under fair value method were similarly repriced as 
of  January  1,  2005.    As  a  result,  stock  compensation  expense  of  $158,531  for  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.

The value of options issued to non-employees is determined using Black-Scholes method using the 
following assumptions: volatility of 100%, risk free interest rate of 4.46%, expected life of option 5

accounted  for  its  employee  stock  options  and  employee  stock  purchase  plan  under  the  fair  value 
method of SFAS No. 123.  The fair value for these options was estimated at the dates of grant using 
the  Black-Scholes  pricing  model.    The  weighted  average  fair  value  of  the  options  granted  to 
employees under this method is $0.63 per option for a total cost of $2,340,000 (2004- $714,400).

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,  2005  and  2004,  the  Company  had  approximately  $10,465,390  and  $7,073,442, 
respectively, of federal and state net operating loss carryforwards available to offset future taxable income; 
such carryforwards expire in various years through 2024. 

10.  Government Assistance 

On  December  13,  2003,  the  Company  accepted  an  offer  of  a  conditional  grant  from  the  Montgomery 
County Department of Economic Development for $100,000 to assist in the growth and expansion of the 
Company, which amount was received in February 2004. The terms of the offer state that $50,000 of the 
grant is convertible to a loan repayable over three years bearing interest at 20% per annum if, at any time 
within five years from receipt of the grant, the  Company's annual net revenues exceed $1,000,000 or the 
Company obtains aggregate equity financing of over $2,000,000.  This portion of the grant was recorded in 
accounts  payable  at  December  31,  2004.  The  terms  of  the  grant  also  state  that  the  remaining  $50,000 
balance of the grant would be permanently forgiven when performance criteria relating to lease of premises 
and  employment  commitments  are  met,  provided  that  the  forgiven  amounts  may  only  be  applied  to 
reducing  business-related  expenses.    In  2004  upon  satisfaction  of  the  performance  criteria,  the  $50,000 
amount  was  forgiven  and  applied  to  lease  payments  and  was  recorded  as  a  reduction  of  business-related 
expenses.  Following the Company's February 2005 convertible debt financing, the remaining $50,000 was 
converted into a loan pursuant to the terms of the grant and was paid off by the Company in March 2005.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight 
Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance 
about whether the financial statements are free of material misstatement. The Company is not required to have, 
nor were we engaged to perform, an audit of its internal control over financial reporting. Our audit 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 audit 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, 2005 and the results of its operations and its 
cash flows for the year ended December 31, 2005 and the cumulative period from inception (March 19, 2001) to 
December 31, 2005, in conformity with accounting principles generally accepted in the United States of 
America.

Report of Independent Registered Public Accounting Firm 

To the Board of Directors and Stockholders of  
Rexahn Pharmaceuticals, Inc. (formerly Rexahn, Corp) 

We have audited the accompanying balance sheet of Rexahn Pharmaceuticals, Inc. (a development stage 
company) as at December 31, 2004 and the related statements of operations, changes in stockholders' equity and 
cash flows for the year then ended. These financial statements are the responsibility of the Company's 
management. Our responsibility is to express an opinion on these financial statements based on our audits.  

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

In our opinion, the financial statements referred to above present fairly, in all material respects, the 

financial position of Rexahn Pharmaceuticals, Inc., as at December 31, 2004 and the results of its operations, 
changes in stockholders' equity and cash flows for the year then ended in conformity with U.S. generally 
accepted accounting principles.  

The accompanying financial statements have been prepared assuming that the Company will continue as 

a going concern. The Company has suffered recurring losses from operations since inception that raise 
substantial doubt about its ability to continue as a going concern.  The financial statements do not include any 
adjustments that might result from the outcome of this uncertainty.

Not applicable. 

Item 8A.  Controls and Procedures 

Based on their most recent evaluation, which was completed as of the end of the period, December, 

2005, covered by this Annual Report on Form 10-KSB, the Company's Chief Executive Officer and Chief 
Financial Officer believe the Company's disclosure controls and procedures (as defined in Exchange Act Rules 
13a-14 and 15d-14) are effective to ensure that information required to be disclosed by the Company in 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.

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. 

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  

NY3 - 405381.15 

66 

 
• 

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.  

(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 

NY3 - 405381.15 

67 

 
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. 

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 

NY3 - 405381.15 

68 

 
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 provides that Dr. 
Steinfels will 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 continues beyond 
September 12, 2007, such employment will become "at-will," unless his employment agreement is expressly 
extended.   

Dr. Steinfels will be paid an annual base salary of $200,000, which will be subject to periodic review 
and potential increase at the Board's sole discretion. During his employment, Dr. Steinfels 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, Dr. Steinfels must be actively employed by the 
Company on the date on which such cash bonus is scheduled to be paid to him.  Dr. Steinfels, during his 
employment, 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, Dr. Steinfels 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 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 are 
substantially similar to Mr. Jeong's 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, 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 

On August 3, 2005, we engaged Montgomery Pacific Group ("MPG") to act as our financial advisor for 
a one-year term in connection with our growth strategies, certain in licensing activities and acquisition of certain 
assets.  In consideration of the services, we agreed to pay MPG an advisory fee, consisting of an initial retainer 
fee and success fees subject to the successful closing of licensing transactions, acquisitions and private 
placements.  We paid an initial retainer fee of $50,000 in 2005.  Dr. John Holaday, one of our directors, is 
currently a partner at MPG. 

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 RX-0201, one of our drug candidates, for sale and use in Asian 
countries.  We contributed a license to technology relating to RX-0201, 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 RX-0201 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 6.46% of outstanding common stock.   

NY3 - 405381.15 

71 

 
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.
