ITEM 1. DESCRIPTION OF BUSINESS.

Overview

We are a development stage pharmaceutical company that seeks to acquire and develop innovative products for the treatment of a variety of human diseases. Our strategy is to develop technologies that address important unmet medical needs or offer improved, cost-effective alternatives to current methods of treatment. Specifically, we are developing prescription products for multiple autoimmune disorders including rheumatoid arthritis, psoriasis, inflammatory bowel disease (IBD) and cancer along with our development of a novel therapeutic agent for the treatment of neurogenic orthostatic hypotension and related conditions and diseases.

Since inception in 2002, we have focused primarily on organizing and staffing our company, negotiating in-licensing agreements with our partners, acquiring, developing and securing our proprietary technology, synthesis and manufacturing of investigational compounds, participating in regulatory discussions with the United States Food & Drug Administration, or the FDA, the European Medicines Agency, or the EMEA, and other regulatory agencies, undertaking pre-clinical and clinical trials of our product candidates and raising capital. We are a development stage company and have generated no revenues since inception. We do not anticipate generating any product revenue until approvals are successfully obtained from the FDA or equivalent foreign regulatory bodies to begin selling pharmaceutical/biotech candidates.

We have retained a management team with leading core competencies and expertise in numerous fields, including manufacturing, research, clinical, regulatory and business development. Our management and advisors are comprised of experienced pharmaceutical and biotechnology industry veterans and respected experts. We are led by Chief Executive Officer, Dr. Simon Pedder, formerly Vice President, Pharmaceutical Business, Oncology at Hoffmann-La Roche Inc., who has over 15 years of senior pharmaceutical management experience, including drug development and business experience. During his time at Roche, Dr. Pedder was responsible for a number of global development programs, successful registrations and product launches.

Product Pipeline Summary

Currently, we are developing two platform technologies that each consist of a portfolio of molecules for the treatment of various autoimmune/inflammatory diseases. The first and most advanced platform is a portfolio of metabolically inert antifolate molecules for which we have either filed our own patent applications or have licensed the exclusive rights, including our lead product candidate CH-1504. CH-1504 is an orally available molecule with potent anti-inflammatory, autoimmune and anti-tumor properties. We believe that CH-1504 has potential application in multiple autoimmune diseases, particularly in the treatment of rheumatoid arthritis, as demonstrated in a series of pre-clinical studies and a small, pilot clinical study. Additional potential indications include psoriasis, inflammatory bowel disease, psoriatic arthritis and several different kinds of cancer.

The second platform is a portfolio of dihydroorotate dehydrogenase (DHODH) inhibiting compounds known as the I-3D portfolio that are being co-developed with Active Biotech AB from whom we obtained exclusive North and South American commercial rights to all compounds in the portfolio as part of our co-development and commercialization agreement. Current preclinical animal data for this portfolio of compounds have shown potential applications in autoimmune diseases and transplantation.

1

In May 2006, we executed an exclusive license agreement with Dainippon Sumitomo Pharma Co., Ltd., and initiated development of droxidopa, an orally active synthetic precursor of norepinephrine currently approved and marketed in Japan for the treatment of symptomatic orthostatic hypotension, freezing gait in Parkinson’s disease, and for intra dialytic hypotension. We intend to begin Phase III trials in the second half of 2007 for treatment of symptomatic neurogenic orthostatic hypotension in patients with primary autonomic failure, dopamine-ß-hydroxylase deficiency, or nondiabetic autonomic neuropathy. This indication is consistent with the orphan drug status designation granted to us in the United States by the FDA on January 17, 2007.

Corporate History

Our operating company was incorporated in Delaware in April 2002 under the name Aspen Therapeutics, Inc., and changed its name to Chelsea Therapeutics, Inc. in July 2004. On February 11, 2005, Chelsea Therapeutics, Inc. completed a merger with Ivory Capital Corporation, a publicly traded Colorado corporation formed in May 1988. At the time of the transaction, Ivory Capital had only nominal assets and no operating activities. In connection with this merger transaction, a wholly owned subsidiary of Ivory Capital Corporation merged with and into Chelsea Therapeutics, Inc., with Chelsea Therapeutics, Inc. remaining as the surviving corporation and a wholly owned subsidiary of Ivory Capital Corporation. In connection with the merger, the former stockholders of Chelsea Therapeutics, Inc. received 96.75% percent of our outstanding equity on a fully diluted basis. Pursuant to the terms of the merger, the sole officer and director of Ivory Capital Corporation prior to the merger was replaced with the officers and directors of Chelsea Therapeutics, Inc.

On June 17, 2005, Ivory Capital Corporation formed a wholly owned subsidiary in Delaware named Chelsea Therapeutics International, Ltd. for the purposes of reincorporating in Delaware. On July 28, 2005, Ivory Capital Corporation merged with Chelsea Therapeutics International, Ltd., with Chelsea Therapeutics International, Ltd. as the surviving corporation. As a result, Chelsea Therapeutics International, Ltd. is the public reporting company and is the 100% owner of Chelsea Therapeutics, Inc., its operating subsidiary.

Except where the context provides otherwise, references to “we,” “us,” “our” and similar terms mean Chelsea Therapeutics International, Ltd., Ivory Capital Corporation and Chelsea Therapeutics, Inc. When we refer to business and financial information relating to periods prior to December 31, 2004, we are referring to the business and financial information of Chelsea Therapeutics, Inc. unless the context requires otherwise. When we refer to business and financial information for periods between January 1, 2005 and July 28, 2005, we are referring to the business and financial information of Ivory Capital Corporation.

Plan of Operation

Our plan of operation is to continue implementing our business strategy, especially the clinical development of our current drug candidates including droxidopa, CH-1504 and drug candidates from the I-3D portfolio. We also continue to explore the feasibility of other licensed or newly developed compounds and to expand our drug candidate portfolio by acquiring additional drug technologies for development. We expect our principal expenditures during the next 18 months to include:

• operating expenses, including general and administrative, marketing and business development expenses;

• Product development expenses, including the costs incurred with respect to applications for and implementation of our clinical trials for droxidopa, CH-1504 and any other antifolate molecules, compounds from the I-3D portfolio and/or additional compounds that we may license.

As part of our planned expansion, we anticipate hiring additional scientific, marketing, and administrative staff. In addition, we intend to continue using clinical research organizations and third parties to perform our clinical studies and manufacturing.

DROXIDOPA

Overview

Orthostatic hypotension is a sudden, decrease in blood pressure when a person assumes a standing position and is characterized by lightheadedness, dizziness, blurred vision and syncope. There are multiple known causes for orthostatic hypotension including those that are considered cardiovascular, endocrine or neurological (or neurogenic) in nature.

Neurogenic orthostatic hypotension results from a deficient release and/or activity of norepinephrine, a neurotransmitter used by autonomic nerves to send signals to the blood vessels and the heart.

We estimate that nearly 300,000 patients suffer from chronic, symptomatic NOH in the United States and the European Union. This condition is commonly associated with Parkinson’s disease, pure autonomic failure and multiple system atrophy a name that encompasses disorders previously known as striatonigral degeneration, olivoponto-cerebellar atrophy and the Shy-Drager syndrome.

Product Description

Droxidopa is an orally active synthetic precursor of norepinephrine currently approved and marketed by Dainippon Sumitomo Pharma Co., Ltd., or DSP, in Japan for the treatment of orthostatic hypotension. By producing and replenishing depleted norepinephrine via endogenous enzymatic pathways, droxidopa is believed to allow for the re-uptake of norepinephrine into peripheral nervous system neurons and/or stimulating receptors for vasoconstriction and providing physiological improvement in symptomatic NOH patients.

Originally approved in 1989 for the treatment of frozen gait or dizziness associated with Parkinson’s disease and for the treatment of orthostatic hypotension, syncope or dizziness associated with Shy-Drager syndrome and Familial Amyloidotic Polyneuropathy, DSP expanded its Japanese marketing approval in 2000 to include prevention of vertigo, dizziness and weakness associated with hypotension in patients with end stage renal disease (ESRD) undergoing hemodialysis.

Clinical Development

In January 2007, the FDA granted orphan drug status for droxidopa for the treatment of symptomatic NOH in patients with primary autonomic failure (Parkinson’s disease, multiple system atrophy, and pure autonomic failure), dopamine-ß-hydroxylase deficiency, or nondiabetic autonomic neuropathy. In the United States, orphan drug status provides seven (7) years of marketing exclusivity and may impact FDA requirements for clinical trials, potentially reducing the time and expense required for such trials. We have also requested orphan drug status in Europe. Although we can expect 10 years of data exclusivity for droxidopa upon approval in Europe as a new chemical entity, orphan drug status could impact requirements for clinical trials in Europe, thereby reducing the time and costs associated with our development of droxidopa for this market.

In securing development rights from DSP, we obtained exclusive access to a substantial body of clinical safety and efficacy data related to droxidopa’s twenty-year combined clinical and commercial development by DSP. We believe this data to be applicable to both the United States and European Union regulatory approval process. This data is expected to reduce the required clinical testing for United States and European Union marketing approval and expedite the critical path to commercialization. We are currently planning to initiate a global Phase III trial of droxidopa in the second half of 2007 that, in combination with data secured from DSP, is expected to support applications for marketing approval in both the United States and the European Union. We cannot predict with certainty the timing of our clinical trials, if or when we might submit an NDA or whether such NDA will be accepted. However, assuming approval of the NDA, we currently estimate market launch no sooner than 2009.

Additional Potential Indications for Droxidopa

As we proceed to develop droxidopa for the treatment of symptomatic NOH, an indication for which we believe there exists a strong body of available clinical data and an immediate commercial opportunity, we will also evaluate other therapeutic indications for which we believe droxidopa either has shown or may provide clinical benefit.

Intra dialytic hypotension, or IDH, is the most common adverse event during routine hemodialysis. IDH is often defined as a decrease in systolic blood pressure by ³ 20 mm Hg or a decrease in mean arterial pressure by 10 mm Hg. IDH has been reported in approximately 25% of all hemodialysis patients, with elderly patients reporting higher incidences. Many adverse hemodialysis events, including headaches, lightheadedness, nausea, cramps, and seizures, are associated with IDH. These complications can routinely interrupt dialysis sessions, resulting in insufficient uremia toxin removal and necessitating repetition of the procedure. Interruptions due to IDH increase the costs of both the dialysis treatment sessions and the long-term care of less healthy hemodialysis patients. Pivotal clinical studies conducted by DSP have demonstrated the efficacy of droxidopa in the prevention of vertigo, dizziness and weakness associated with hypotension in hemodialysis patients. Subsequently, in 2000, after showing benefit in clinical trials, DSP received expanded marketing approval in Japan for this indication. We plan to initiate a clinical trial with droxidopa in IDH prior to the end of 2007.

Prior independent clinical studies and ongoing research suggest that defects in the autonomic nervous system (such as altered norepinephrine levels and activity) may play a role in either the underlying cause or exacerbation of the symptoms associated with multiple diseases commonly grouped as dysautonomias. These indications include: chronic pain, urinary stress incontinence, postural orthostatic tachycardia syndrome, neurocardiogenic syncope, fibromyalgia and chronic fatigue syndrome.

Scientists and physicians have for a long time suggested a strong association and/or significant correlation of symptoms between low blood pressure (caused by either NOH or neurally mediated hypotension (NMH)) and dysautonomia associated diseases. Research has shown a significant association between NMH and two specific dysautonomias, fibromyalgia (FM), and chronic fatigue syndrome (CFS). Unlike OH, which is a problem with blood pressure regulation immediately after standing, NMH is characterized by a drop in blood pressure only after standing for long periods of time. NMH occurs due to a miscommunication between the heart and brain resulting in a failure to maintain appropriate increases in heart rate after standing for prolonged periods. This is believed to be a problem related specifically to deficient nerve function in the left ventricle that prevents the heart rate from increasing when needed. Instead of increasing, the heart rate actually drops, preventing the necessary amount of blood from being circulated. This leads to NMH symptoms like dizziness and fainting, which are often seen in patients with FM, CFS and other dysautonomias. As norepinephrine naturally regulates both heart rate and vasoconstriction, droxidopa could be an appropriate alternative therapy (among others such as salt, Florinef^® and Midodrine) to treat these specific symptoms by enhancing the body’s ability to naturally regulate these functions. Further studies will be needed to determine the contribution of either NMH or NOH to other major components of autonomic diseases such as pain, fatigue, weakness, and incontinence. Furthermore, randomized trials will be needed to indicate whether droxidopa improves the hypotension and whether this in turn shows benefit in additional symptomology within these disease syndromes.

We intend to conduct proof of concept trials to investigate the benefits of droxidopa, if any, in treating both the orthostatic intolerance symptom and the additional symptoms which make up the various dysautonomia conditions. We are currently working with key opinion leaders in FM and CFS concerning the timing and size of an initial trial which would be expected to start sometime after the initiation of clinical trials in NOH and IDH later this year.

Droxidopa Competition

Midodrine (ProAmatine^®)

Midodrine is currently the only FDA approved therapeutic for the treatment of orthostatic hypotension. Midodrine, originally developed by Roberts Pharmaceuticals (later acquired by Shire^®) under the brand name ProAmatine^®, is an alpha-agonist that works by stimulating alpha receptors, subsequently increasing vasculature tone and thereby producing an elevation in blood pressure. Given this direct mechanism of action, it is not surprising that supine hypertension is the most frequently occurring adverse event associated with its use. Midodrine’s product label contains a black box warning and Midodrine does not specifically address neurogenic orthostatic hypotension.

Other than the increase in blood pressure caused by vasoconstriction, additional midodrine side effects include paresthesia, piloerection, dysuria, and pruritis. Annual sales (branded and generic) in the United States total approximately $60 million. In addition to Shire’s manufacturing of the ProAmatine brand, Mylan Pharmaceuticals, Eon Labs and Impax Laboratories are generic manufacturers of the compound.

Fludrocortisone (Florinef^®)

Fludrocortisone is also widely used in the treatment of orthostatic hypotension although this specific indication has not been approved by the FDA. Fludrocortisone is a synthetic adrenocortical steroid possessing very potent mineralocorticoid properties and high glucocorticoid activity. Fludrocortisone, in small oral doses (0.1 mg.) produces marked sodium retention and increased urinary potassium excretion leading to enhanced plasma volume and a rise in blood pressure. Side effects include hypertension, water & sodium retention and K+ loss. Fludrocortisone is not FDA approved for this indication. The mechanism of action for fludrocortisone does not specifically address NOH.

Droxidopa Marketing

Our marketing plan for droxidopa includes the establishment of a marketing and sales organization in the United States. With regard to the European Union and other markets, we would expect to partner with or license droxidopa to companies with established infrastructure in those markets.

METABOLICALLY INERT ANTIFOLATES & CH-1504

Overview

Our portfolio of novel antifolate compounds was originally developed by Dr. M. Gopal Nair and licensed by us in 2004. A library of orally available and metabolically inert antifolate compounds with potent autoimmune, anti-inflammatory and anti-tumor properties, these compounds are engineered to treat a broad range of immunological disorders with less harmful and unpleasant side effects than those typically associated with classical antifolates. Diseases that may potentially be treated with metabolically inert antifolates include rheumatoid arthritis, psoriasis, inflammatory bowel disease, cancer and other immunological disorders.

Rheumatoid arthritis is a chronic inflammatory disease that leads to pain, stiffness, swelling and limitation in the motion and function of multiple joints. If left untreated, rheumatoid arthritis can produce serious destruction of joints that frequently leads to permanent disability. Though the joints are the principal body part affected by rheumatoid arthritis, inflammation can develop in other organs as well. The disease currently affects over two million Americans, almost 1% of the population, and is two to three times more prevalent in women. Onset can occur at any point in life with most patients developing the disease between the ages of 35 and 50.

Product Description

CH-1504, the lead product candidate in our antifolate portfolio, potently inhibits dihydrofolate reductase, an enzyme required for cell proliferation. Preclinical and clinical data to date support CH-1504’s superior safety and

5

tolerability profile, as well as possible enhanced potency versus methotrexate or MTX, currently the leading antifolate treatment and standard of care for a broad range of abnormal cell proliferation diseases.

CH-1504 is a unique antifolate that we believe might have clinical advantages over MTX as it might have superior efficacy, less toxicity and increased tolerability. Potential advantages of CH-1504 over existing therapies include:

• higher response rate, including efficacy in patients that have failed MTX therapy;

• faster onset of action;

• better tolerability; and

• superior toxicity profile.

The rationale and scientific data to date indicate that CH-1504 might be more tolerable than other rheumatoid arthritis drugs currently on the market. For example, toxicity is a major factor limiting MTX’s long-term use in treating rheumatoid arthritis. CH-1504, on the other hand, appears to be devoid of the toxicities related to the formation of metabolites. CH-1504 is a metabolism-blocked antifolate with significant pre-clinical data that indicates enhanced safety and tolerability due to the lack of metabolism. Liver and kidney toxicity is manifested frequently during MTX therapies for rheumatoid arthritis, psoriasis, other immunological diseases and cancer and it has been reported that the metabolic byproducts of MTX may play a significant role in these toxicities.

We believe that in rheumatoid arthritis patients, CH-1504 might have significant clinical advantages over MTX due to its metabolic stability. Because of this stability, it can be hypothesized that in those patients who are unresponsive to MTX, CH-1504 might be clinically efficacious since it is not deactivated by these enzymatic processes.

Clinical Development

In June 2005, we commenced Phase I single and multiple dose escalation clinical trials of CH-1504 in healthy volunteers. These trials were conducted at Guy’s Hospital in London under the Clinical Trial Authorization, or CTA, issued by the Medicines and Healthcare Products Regulatory Agency, the United Kingdom’s health authority. The in vivo portion and preliminary analysis of these trials were completed in December 2005.

Continuing evaluation of these results in light of additional preclinical data suggested that the bioavailability of CH-1504 was low and had significant pharmacokinetic (“PK”) variability. Discussions among our personnel, external consultants and potential partners suggested the bioavailability of CH-1504 could be improved through standard alterations to the formulation. Consequently, the company engaged in a comprehensive screening of approximately 25 commercially viable salts and, based on the results of that screening process, selected a disodium salt of CH-1504 to take forward. Having selected a salt formulation, we initiated complimentary pharmaceutical enhancements to the compound that include evaluation of such solid dosage form options as compounding with wetting agents, buffers, enteric coatings or alternatively, liquid filled hard gel capsule technology. The primary goal of these formulation efforts was to improve the solubility of the compound, increasing bioavailability and reducing PK variation of CH-1504.

Following the reformulation of CH-1504, we intend to conduct the required human bioequivalence studies to determine a comparable dose range for global Phase II trials in rheumatoid arthritis. Preliminary discussions with the appropriate regulatory authorities and consultants suggest that we will not be required to conduct bridging toxicology studies or complete additional animal toxicology studies prior to the initiation of our planned bioequivalence trials. Additionally, we do not expect that a maximum tolerated dose trial will be required prior to commencing our Phase II trials. We currently expect that all necessary formulation work will be complete in time

6

to initiate bioequivalence trials in the second quarter of 2007. We anticipate that the safety and pharmacokinetic data from our U.K. Phase I clinical trial along with the results of our planned bioequivalence study will enable us to initiate regulatory agency submissions in support of a multi-national Phase II clinical trial in rheumatoid arthritis. Upon completion of the Phase III studies in rheumatoid arthritis, and having a pre-NDA meeting with the FDA and European Union agencies, we hope to use data from these studies to file an NDA. We cannot predict with certainty the timing of our clinical trials, if or when we might submit an NDA or whether such NDA will be accepted. However, we currently estimate a global filing of the NDA no sooner than 2010, and assuming approval of the NDA, a market launch no sooner than 2011.

Other Potential Indications for CH-1504

As we proceed in our clinical development of CH-1504 for rheumatoid arthritis, we expect to continue our evaluation of its potential in other indications. In particular, should an analysis of interim data from our planned Phase II study in rheumatoid arthritis be supportive, we plan to initiate a Phase II proof of concept trial in psoriasis during 2008. Additional potential indications for CH-1504 include inflammatory bowel disease, psoriatic arthritis and several different kinds of cancer. As CH-1504 advances in rheumatoid arthritis and psoriasis, we will begin to focus on the timing of clinical programs for CH-1504 in these additional indications. Notwithstanding the foregoing, because of our limited funding, clinical studies will initially be pursued in rheumatoid arthritis, followed conditionally by psoriasis.

Pre-clinical studies conducted at the National Cancer Institute have indicated that CH-1504 might also be a better anti-cancer therapy than MTX. It is believed that CH-1504 enters cells by the reduced folate carrier, or RFC, transport system pathway and might be transported up to 4.5 times more efficiently than MTX. CH-1504 has exhibited promising anti-tumor activity in multiple models using a wide variety of cell lines and tumor types. In addition, CH-1504 is active in anti-tumor models known to be resistant to classical polyglutamylated antifolates such as MTX. Collectively this data suggests that CH-1504 is a metabolism-blocked classical antifolate that might be superior to MTX in these diseases.

Antifolate Competition

There are many different drugs that are used to treat rheumatoid arthritis, including hormones, small molecules and biologics, which are manufactured using recombinant technology. The normal course of therapy for rheumatoid arthritis begins with analgesics, such as aspirin, and non-steroidal anti-inflammatory agents, followed by disease modifying anti-rheumatic drugs (DMARDs), including low dose steroids, MTX, DHODH inhibitors and biologics, and, finally, reconstructive joint surgery for patients failing all therapies. DMARDs are the only drugs that have been shown to alter the course of disease.

We believe that because of its possible low toxicity profile and increased effectiveness, CH-1504 might replace MTX and penetrate the non-steroidal anti-inflammatory drug (NSAID) and biologic markets, giving it the potential to become a widely prescribed therapy for rheumatoid arthritis. Medical practitioners prescribe NSAIDs because of their low toxicity. However, if CH-1504’s safety profile and anti-rheumatic effect are superior to MTX , doctors might initiate CH-1504 earlier in the course of treatment than currently prescribed antifolates. The emerging treatment paradigm for medical practitioners is to move patients from NSAIDs to DMARDs early in the disease to improve long-term clinical outcomes as measured by a reduction in joint destruction. The availability of a DMARD that is safer and better tolerated might be expected to encourage this approach. Also, because CH-1504 might not develop treatment resistance (related to metabolism differences) and might be better tolerated, it might delay or decrease the use of expensive biologics in the early stage of the disease. Additionally, as seen with MTX, medical practitioners might administer CH-1504 in combination with biologics as the disease progresses.

The hypothesized efficacy and safety profile of CH-1504 would potentially make it an attractive alternative to existing antifolate and biologic therapies for inflammatory and oncological diseases. We believe CH-1504 can

7

achieve market share not only as a monotherapy at the expense of existing and established products, but also as a therapy prescribed in combination with biologics. Some of the products CH-1504 would compete with include MTX, Johnson & Johnson’s Remicade^®, Amgen’s Enbrel^®, Abbott Laboratories’ Humira^® and Aventis’ Arava^®.

Currently Available Antifolates. MTX, a classical antifolate, was originally used as a chemotherapy drug to treat certain kinds of cancer, but was also found to be beneficial in treating inflammatory arthritis and psoriasis. MTX is generic and marketed in both injectable and oral formulations by multiple companies including Barr Laboratories, Boehringer Ingelheim Pharma, Mayne Pharma and Mylan Laboratories.

Currently Available Biologics. Although there have been positive results for biologics, we believe physicians are likely to reserve anti-tumor necrosis factor (anti-TNF) and other biologic therapies for patients who have failed initial MTX monotherapy. Despite increased aggressiveness of treating physicians and easier reimbursement, front line use or combination therapy with multiple biologics is unlikely to occur due to their high costs and side effect profile. Enbrel^®, Humira^® and Remicade^® are TNF blockers that have been approved by the FDA over the last six years and are the top selling biologics for rheumatoid arthritis. These three TNF blockers are administered to patients by injection and can be used alone or in combination with other DMARDs or NSAIDs such as aspirin or ibuprofen. Enbrel^®, which is developed by Amgen, is the top selling biologic for rheumatoid arthritis, and is also indicated for juvenile rheumatoid arthritis, early rheumatoid arthritis, psoriatic arthritis and ankylosing spondylitis. Enbrel^® is estimated to have had global sales of $1.9 billion for the treatment of rheumatoid arthritis in 2004. Remicade^® is a chimeric anti-TNF monoclonal antibody developed by Johnson & Johnson for the treatment of rheumatoid arthritis and Crohn’s disease with combined global sales of $2.1 billion in 2004. Abbott Laboratories’ Humira^® had 2004 global sales of $852 million. Both Remicade^® and Humira^® contain black box warnings for tuberculosis. Rituxan is currently marketed by Genetech and Roche for rheumatoid arthritis in patients refractory to other DMARD therapy. CTLA4Ig, developed by Bristol-Myers Squibb, is being studied as a once-monthly infusion for rheumatoid arthritis. The drug has been recently approved by the FDA and earlier data, as reported by Bristol-Myers Squibb, has shown the drug to be safe as a monotherapy and combination.

DMARDs in Development. Celltech is currently developing CDP-870, a pegylated anti-TNF antibody for the treatment of rheumatoid arthritis and Crohn’s disease. CDP-870 is currently in Phase III studies as a monotherapy and in combination with MTX.

Antifolate Marketing

Given the size of the rheumatoid arthritis market, the vast sales forces required to compete in this market, and the necessary infrastructure required, our marketing strategy for CH-1504 is likely to include contracting with or licensing to third parties, particularly for territories outside the United States. It is possible that we might directly commercialize or co-promote this or another of our antifolate compounds in the smaller therapeutic indications such as psoriasis or inflammatory bowel disease. Out-licensing arrangements might be negotiated and entered into prior to one or more of our antifolate drug candidates being approved for marketing.

I-3D PORTFOLIO

Overview

In May of 2006, we signed an agreement with Active Biotech for the co-development and commercialization of the I-3D portfolio, a group of orally active compounds that inhibit the enzyme dihydroorotate dehydrogenase (DHODH) for the treatment of autoimmune diseases and transplant rejection. At the time of the agreement, Active Biotech had already isolated more than 15 compounds and conducted extensive preclinical modeling resulting in the identification of two potential lead compounds. Pursuant to the agreement, a joint development committee was established to direct the continued development of I-3D compounds with the initial objective of selecting a lead compound with which to initiate Phase I clinical trials.

Having previously demonstrated proof of concept in both rheumatoid arthritis and transplant rejection in animal models, the joint development committee selected AB-224050 as the first I-3D compound to undergo IND-enabling toxicology studies during the third quarter 2006. As part of the ongoing evaluation and preparation for Phase I trials, the joint development committee initiated a Phase 0 (micro-dosing) study to evaluate the half-life of AB-224050 in humans in the first quarter of 2007. Based on the results of the micro-dosing study and other ongoing preclinical activity, it has now been determined that, while demonstrating a significantly shorter half-life than Arava^®, AB-224050 will require additional work prior to the commencement of Phase I clinical trials. In 2007, the joint development committee plans to continue preclinical optimization of AB-224050 and conduct further comparisons of AB-224050 versus other compounds in the I-3D portfolio prior to initiating Phase I clinical trials. Accordingly, the I-3D Phase I program is not expected to commence earlier than 2008.

I-3D Additional Indications

In addition to therapeutic applications in rheumatoid arthritis, compounds from the I-3D portfolio are believed to have broad clinical application in immune-mediated inflammatory disorders including transplant rejection, psoriasis and systemic lupus erythematosus.

I-3D Competition

As discussed in conjunction with our antifolate program, there are many different drugs that are used to treat rheumatoid arthritis, including hormones, small molecules and biologics, which are manufactured using recombinant technology. The normal course of therapy for rheumatoid arthritis begins with analgesics, such as aspirin, and non-steroidal anti-inflammatory agents, followed by disease modifying anti-rheumatic drugs or DMARDs, including MTX, DHODH inhibitors, low dose steroids and biologics, and, finally, reconstructive joint surgery for patients failing all therapies. DMARDs are the only drugs that have been shown to alter the course of disease.

Leflunomide (Arava^®), first marketed in 1998 as an oral DMARD for the treatment of rheumatoid arthritis, is a cytotoxic that is believed to work by inhibiting the DHODH enzyme to prevent DNA synthesis and limit abnormal cell proliferation. Leflunomide is known to have a half-life of greater than two weeks. Given the length of time required to reach therapeutic levels, a higher dose (loading dose) is initially required before dropping down to a lower maintenance dose. Side effects include diarrhea (27%), dyspepsia (10%) abdominal pain (5%), or nausea (13%) and altered liver function (10%).

I-3D Marketing

Our agreement with Active Biotech provides us with the exclusive North and South American commercial rights to all drugs within the I-3D portfolio, while Active Biotech retains rights for the remaining global markets. In addition to sharing development costs, both parties have agreed to pay the other royalty payments on sales in their respective markets. Given the size of the rheumatoid arthritis market, the vast sales forces required to compete in that market, and the necessary infrastructure required, our marketing strategy for I-3D compounds would likely be similar to that of our strategy for CH-1504 and may include contracting with or licensing to third parties. It is possible that, at some point, we might co-promote in the larger therapeutic markets such as rheumatoid arthritis or market I-3D compounds on our own accord for indications other than rheumatoid arthritis. Any such arrangements might be negotiated and entered into prior to one or more of our I-3D drug candidates being approved for marketing.

Scientific Advisory Boards

We retain the services of certain qualified individuals on our Scientific Advisory Boards (SABs) which normally meet at least twice a year. Meetings or consultations with SAB members are held more often when significant developments arise or new information becomes available that require expert review. The boards provide an opportunity to review our scientific, research and clinical development plans from the perspective of

9

experts and key opinion leaders in the medical community. Specifically, the SABs provide advice concerning the design of clinical research protocols to be utilize for the development of the company’s drug candidates and they provide an opportunity to test the validity of the company’s assumptions regarding the attitudes of the medical community relative to various drug characteristics that might be highlighted during development.

Government Regulation

The research, development, testing, manufacture, labeling, promotion, advertising, distribution, and marketing, among other activities, for our potential products are extensively regulated by governmental authorities in the United States and other countries. Satisfaction of FDA requirements or requirements of state, local and foreign regulatory agencies typically takes several years, and the actual time required can vary substantially based upon the type, complexity and novelty of the pharmaceutical product. Satisfaction of these requirements will impose costly procedures upon our activities, and we cannot be certain that the FDA or any other regulatory agency will grant approval for any of our products under development on a timely basis, if at all.

Success in preclinical or early-stage clinical trials does not assure success in later-stage clinical trials. Data obtained from pre-clinical and clinical activities are not always conclusive and are susceptible to varying interpretations that could delay, limit or prevent regulatory approval. Failure to comply with the applicable requirements might subject us to administrative or judicial sanctions in the United States, such as the FDA’s refusal to approve pending NDAs, warning letters, product recalls, product seizures, total or partial suspension of production or distribution, injunctions, and/or criminal prosecution. Even if a product receives regulatory approval, the approval might be significantly limited to specific indications or uses. After regulatory approval is obtained, later discovery of previously unknown problems with a product might result in restrictions on the product or even complete withdrawal of the product from the market. Delays in obtaining, or failures to obtain regulatory approvals would have a material adverse effect on our business.

Drug Approval Process in the United States

In the United States, the FDA regulates drugs under the Federal Food, Drug, and Cosmetic Act, or FDCA, and its implementing regulations. None of our drugs may be marketed in the United States until the drug has received FDA approval. The steps required before a drug might be marketed in the United States include:

• preclinical laboratory tests, animal pharmacology and toxicology studies, and formulation studies;

• submission to the FDA of an IND for human clinical testing, which must become effective before human clinical trials might begin in the United States;

• adequate and well-controlled human clinical trials to establish the safety and efficacy of the drug for each indication;

• submission to the FDA of an NDA;

12

• satisfactory completion of an FDA inspection of the manufacturing facility or facilities at which the drug is produced to assess compliance with current good manufacturing practices, or cGMPs; and

• FDA review and approval of the NDA.

Preclinical tests include laboratory evaluation of product chemistry, toxicity, and formulation, as well as animal studies. The conduct of the preclinical tests and formulation of the compounds for testing must comply with federal regulations and requirements. The results of the preclinical tests, together with manufacturing information and analytical data, are submitted to the FDA as part of an IND, which must become effective before human clinical trials might begin. An IND will automatically become effective 30 days after receipt by the FDA, unless before that time the FDA raises concerns or questions about issues such as the conduct of the trials as outlined in the IND. In such a case, the IND sponsor and the FDA must resolve any outstanding FDA concerns or questions before clinical trials can proceed. We cannot be sure that submission of an IND will result in the FDA allowing clinical trials to begin.

Clinical trials involve the administration of the investigational drug to human subjects under the supervision of qualified investigators. Clinical trials are conducted under protocols detailing the objectives of the study, the parameters to be used in monitoring safety, and the effectiveness criteria to be evaluated. Each protocol must be submitted to the FDA as part of the IND.

Clinical trials typically are conducted in three sequential phases, but the phases might overlap. The study protocol and informed consent information for study subjects in clinical trials must also be approved by an Institutional Review Board for each institution where the trials will be conducted. Study subjects must sign an informed consent form before participating in a clinical trial.

The following describes the phases of clinical drug development:

• Phase I usually involves the initial introduction of the investigational drug into people to evaluate its short-term safety, dosage tolerance, metabolism, pharmacokinetics and pharmacologic actions, and, if possible, to gain an early indication of its effectiveness.

• Phase II usually involves trials in a limited patient population to evaluate dosage tolerance and appropriate dosage, identify possible adverse effects and safety risks, and evaluate preliminarily the efficacy of the drug for specific indications.

• Phase III trials usually further evaluate clinical efficacy and test further for safety by using the drug in its final form in an expanded patient population. There can be no assurance that phase I, phase II, or phase III testing will be completed successfully within any specified period of time, if at all. Furthermore, clinical trials might be suspended by us or the FDA at any time on various grounds, including a finding that the subjects or patients are being exposed to an unacceptable health risk.

Assuming successful completion of the required clinical testing, the results of the preclinical studies and of the clinical studies, together with other detailed information, including information on the manufacture and composition of the drug, are submitted to the FDA in the form of an NDA requesting approval to market the product for one or more indications. The testing and approval process requires substantial time, effort, and financial resources. The agencies review the application and might deem it to be inadequate to support the registration and we cannot be sure that any approval will be granted on a timely basis, if at all. The FDA might also refer the application to the appropriate advisory committee, typically a panel of clinicians, for review, evaluation and a recommendation as to whether the application should be approved. The FDA is not bound by the recommendations of the advisory committee.

The FDA has various programs, including fast track, priority review, and accelerated approval, that are intended to expedite or simplify the process for reviewing drugs, and/or provide for approval on the basis surrogate endpoints. Generally, drugs that might be eligible for one or more of these programs are those for serious or life-threatening conditions, those with the potential to address unmet medical needs, and those that provide meaningful benefit over existing treatments. We cannot be sure that any of our drugs will qualify for any of these programs, or that, if a drug does qualify, that the review time will be reduced.

13

Section 505b2 of the FDCA allows the FDA to approve a follow-on drug on the basis of data in the scientific literature or data used by FDA in the approval of other drugs. This procedure potentially makes it easier for generic drug manufacturers to obtain rapid approval of new forms of drugs based on proprietary data of the original drug manufacturer.

Before approving an NDA, the FDA usually will inspect the facility or the facilities at which the drug is manufactured, and will not approve the product unless the manufacturing site is cGMP compliant. If the FDA evaluates the NDA and the manufacturing facilities as acceptable, the FDA might issue an approval letter, or in some cases, an approvable letter followed by an approval letter. Both letters usually contain a number of conditions that must be met in order to secure final approval of the NDA. When and if those conditions have been met to the FDA’s satisfaction, the FDA will issue an approval letter. The approval letter authorizes commercial marketing of the drug for specific indications. As a condition of NDA approval, the FDA might require post-marketing testing and surveillance to monitor the drug’s safety or efficacy, or impose other conditions.

After approval, certain changes to the approved product, such as adding new indications, making certain manufacturing changes, or making certain additional labeling claims, are subject to further FDA review and approval. Before we can market our product candidates for additional indications, we must obtain additional approvals from the FDA. Obtaining approval for a new indication generally requires that additional clinical studies be conducted. We cannot be sure that any additional approval for new indications for any product candidate will be approved on a timely basis, or at all.

Post-Approval Requirements

Often, even after a drug has been approved by the FDA for sale, the FDA might require that certain post-approval requirements be satisfied, including the conduct of additional clinical studies. If such post-approval conditions are not satisfied, the FDA might withdraw its approval of the drug. In addition, holders of an approved NDA are required to:

• report certain adverse reactions to the FDA;

• comply with certain requirements concerning advertising and promotional labeling for their products; and

• continue to have quality control and manufacturing procedures conform to cGMP after approval.

The FDA periodically inspects the sponsor’s records related to safety reporting and/or manufacturing facilities, including an assessment of compliance with cGMP. Accordingly, manufacturers must continue to expend time, money, and effort in the area of production and quality control to maintain cGMP compliance. We intend to use third party manufacturers to produce our products in clinical and commercial quantities, and future FDA inspections might identify compliance issues at the facilities of our contract manufacturers that might disrupt production or distribution, or require substantial resources to correct. In addition, discovery of problems with a product after approval might result in restrictions on a product, manufacturer, or holder of an approved NDA, including withdrawal of the product from the market.

Orphan Drug Designations

The FDA can grant orphan drug designation to drugs intended to treat a “rare disease or condition,” which generally is a disease or condition that affects fewer than 200,000 individuals in the United States. Orphan drug designation must be requested before submitting an NDA. If the FDA grants orphan drug designation, which it might not, the identity of the therapeutic agent and its potential orphan use are publicly disclosed by the FDA. Orphan drug designation does not necessarily convey an advantage in, or shorten the duration of, the review and approval process. If a product which has an orphan drug designation subsequently receives the first FDA approval for the indication for which it has such designation, the product is entitled to orphan exclusivity, meaning that the FDA will not approve any other applications to market the same drug for the same indication,

14

except in certain very limited circumstances, for a period of seven years. Orphan drug designation does not prevent competitors from developing or marketing different drugs for that indication.

Regulations Outside the United States

Before our products can be marketed outside of the United States, they are subject to regulatory approval similar to that required in the United States , although the requirements governing the conduct of clinical trials, including additional clinical trials that might be required, product licensing, pricing and reimbursement vary widely from country to country. No action can be taken to market any product in a country until an appropriate application has been approved by the regulatory authorities in that country. The current approval process varies from country to country, and the time spent in gaining approval varies from that required for FDA approval. In certain countries, the sales price of a product must also be approved. The pricing review period often begins after market approval is granted. Even if a product is approved by a regulatory authority, satisfactory prices might not be approved for such product.

In Europe, marketing authorizations may be submitted via a centralized, or decentralized (or national level) approach. The centralized procedure is mandatory for the approval of biotechnology products and provides for the grant of a single marketing authorization that is valid in all European Union member states. As of January 1995, a mutual recognition procedure is available at the request of the applicant for all medicinal products that are not subject to the centralized procedure. There can be no assurance that the chosen regulatory strategy will secure regulatory approvals on a timely basis or at all.

Manufacturing

We own no manufacturing facilities, quality control laboratories or warehouses for storage and distribution. We use third-party contractors for manufacturing drug substances under development. We also use contractors for preformulation, formulation and analytical development as well as manufacturing of drug products used for clinical studies. If any of our products are approved by the FDA for marketing, we plan to use third-party contractors for producing the commercial product. This strategy enables us to direct our financial resources to product development without devoting resources to the time and costs associated with building manufacturing plants and laboratories. We plan on implementing this strategy for the foreseeable future to increase the speed of product development and commercialization.

Intellectual Property

We actively seek to obtain, maintain and enforce patent protection for our products, formulations, processes, methods and other proprietary technologies, preserve our trade secrets, and operate without infringing on the proprietary rights of other parties, both in the United States and in other key markets. Our goal is to obtain, where appropriate, the broadest intellectual property protection possible for our current product candidates, including CH-1504 and droxidopa, and any future product candidates and proprietary technologies through a combination of contractual arrangements and patents, both in the United States and other countries.

As of February 23, 2007, our patent estate for the antifolate portfolio, including CH-1504, includes one issued U.S. patent, two pending U.S. patent applications, and several related patent applications pending in countries outside the United States, including Europe and Japan. The issued U.S. patent is U.S. Patent No. 5,912,251, issued June 15, 1999 and entitled “Metabolically Inert Anti-Inflammatory and Anti-Tumor Antifolates”, (the ‘251 patent). The first pending U.S. patent application is U.S. patent application number US 2006-0111272 and a corresponding international PCT patent application, published as WO 2006/029385, is dated September 8, 2005. The second pending U.S. patent application is a provisional U.S. patent application directed to certain new antifolate compounds.

The issued U.S. patent covers our current product candidate, CH-1504, as well as certain analogues of CH-1504, including claims to these compounds as compositions of matter, in pharmaceutical formulations and

15

for use in treatment of certain diseases. The pending U.S. patent applications and international PCT applications expand our proprietary position, claiming additional compounds and their uses as well as new uses of CH-1504. We plan to continue to strengthen our patent estate on our antifolate portfolio by filing and pursuing additional patents.

Our patent estate for droxidopa includes one pending U.S. patent application directed to pharmaceutical compositions comprising droxidopa. We plan to continue to strengthen our patent estate on droxidopa by filing and pursuing additional patents.

The patent estate for the I-3D portfolio includes U.S. patent No. 7,074,831, issued July 11, 2006 and additional patents currently issued and pending, with rights accruing to the Company through the co-development agreement with Active Biotech. We plan to continue to strengthen our patent estate on the I-3D portfolio, in collaboration with Active Biotech, by filing and pursuing additional patents.

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 are unobtainable or difficult to obtain, we rely on trade secret protection and confidentiality agreements. To this end, it is our policy to require all of our employees, consultants, advisors and contractors 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.

Employees

We have attracted and retained a management team with core competencies and expertise in numerous fields, including manufacturing, research, clinical, regulatory and business development. Our management and advisors are comprised of experienced pharmaceutical and biotechnology industry veterans and respected experts. We are led by our Chief Executive Officer, Dr. Simon Pedder, formerly Vice President, Pharmaceutical Business, Oncology at Hoffmann-La Roche Inc., who has over 15 years of senior pharmaceutical management experience, including drug development and business experience. During this time at Roche, Dr. Pedder was responsible for a number of global development programs, successful registrations and product launches.

We have a total of eleven (11) employees. We believe the relationships with our employees are satisfactory. We anticipate that we will need to identify, attract, train and retain other highly skilled personnel. Hiring for such personnel is competitive, and there can be no assurance that we will be able to retain our key employees or attract, assimilate or retain the qualified personnel necessary for the development of our business.

ITEM 1A. RISK FACTORS

This report contains forward-looking statements that involve risks and uncertainties. Our actual results could differ materially from those discussed in this report. Factors that could cause or contribute to these differences include, but are not limited to, those discussed below and elsewhere in this report and in any documents incorporated in this report by reference.

We are a development-stage company and might not be able to commercialize any product candidates.

We are a development-stage company and have not demonstrated our ability to perform the functions necessary for the successful commercialization of any product candidates. The successful commercialization of any product candidates will require us to perform a variety of functions, including:

• continuing to undertake pre-clinical development and clinical trials;

• participating in regulatory approval processes;

• formulating and manufacturing products; and

• conducting sales and marketing activities.

Our operations have been limited to organizing and staffing our company, negotiating in-licensing agreements with out partners, acquiring, developing and securing our proprietary technology, participating in

17

regulatory discussions with the Food and Drug Administration (FDA), the European Medicines Agency (EMEA) and other regulatory agencies and undertaking pre-clinical trials and clinical trials of our product candidates. These operations provide a limited basis for you to assess our ability to commercialize our product candidates and the advisability of investing in our securities.

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

To date, we have generated no product revenue. Until, and unless, we receive approval from the FDA and other regulatory authorities for our product candidates, we cannot sell our drugs and will not have product revenue. Currently, our primary product candidates are droxidopa and CH-1504, and neither is approved by the FDA nor, with the exception of droxidopa which has Japanese approval, any other regulatory agency for sale. Therefore, for the foreseeable future, we will have to fund all of our operations and development expenditures from cash on hand, licensing fees and grants. We expect to seek additional sources of financing, which might not be available on favorable terms, if at all. If we do not succeed in raising additional funds on acceptable terms, we might not be able to complete planned pre-clinical and clinical trials or obtain approval of any product candidates from the FDA and other regulatory authorities. In addition, we could be forced to discontinue product development, reduce or forego sales and marketing efforts and forego attractive business opportunities. Any additional sources of financing will likely involve the issuance of our equity securities, which will have a dilutive effect on our stockholders.

We are not currently profitable and might never become profitable.

We have a history of losses and expect to incur substantial losses and negative operating cash flow for the foreseeable future, and we might never achieve or maintain profitability. Even if we succeed in developing and commercializing one or more product candidates, we expect to incur substantial losses for the foreseeable future and might never become profitable. From inception through December 31, 2006 we had losses of $19.6 million, and we anticipate losses in the range of $20 to 35 million during the 12 to 18 months commencing January 2007. Actual losses will depend on a number of considerations, including:

• the pace and success of pre-clinical development and clinical trials for droxidopa, CH-1504 and other product candidates;

• seeking regulatory approval for our various product candidates;

• obtaining European Orphan Drug approval for droxidopa from the EMEA;

• discussions with regulatory agencies concerning the design of our clinical trials;

• implementing additional internal systems and infrastructure;

• possible out-licensing of our product candidates;

• in-licensing and development of additional product candidates; and

• hiring additional personnel.

We also expect to experience negative cash flow for the foreseeable future as we fund our operating losses and development expenditures. As a result, we will need to generate significant revenue in order to achieve and maintain profitability. We might not be able to generate revenue or achieve profitability in the future and are unlikely to do so in the near term. Our failure to achieve or maintain profitability could negatively impact the value of our securities.

We might not obtain the necessary U.S. or worldwide regulatory approvals to commercialize any product candidates.

We cannot assure you that we will receive the approvals necessary to commercialize our product candidates including droxidopa, CH-1504, or any other product candidate either currently in our drug candidate portfolio or which we might acquire or develop in the future. We will need FDA approval to commercialize our product

18

candidate in the United States and approvals from equivalent regulatory authorities in foreign jurisdictions to commercialize our product candidates in those jurisdictions. In order to obtain FDA approval of any product candidate, we must submit to the FDA a New Drug Application, or NDA, demonstrating that the product 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, depends upon the type, complexity and novelty of the product 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. 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. The approval process might also be delayed by changes in government regulation, future legislation or administrative action or changes in FDA policy that occur prior to or during our regulatory review. Delays in obtaining regulatory approvals might:

• delay commercialization of, and our ability to derive product revenue from, a product candidate;

• impose costly procedures on us; and

• diminish any competitive advantages that we might otherwise enjoy.

Even if we comply with all FDA requests, the FDA may ultimately reject one or more of our NDAs. We cannot be sure that we will ever obtain regulatory clearance for any of our product candidates. Failure to obtain FDA approval of these product candidates, particularly droxidopa or CH-1504, will severely undermine our business and could substantially extend the period before we have a saleable product, leaving us without any source of revenue until another product candidate can be developed. There is no guarantee that we will ever be able to develop or acquire another product candidate.

In foreign jurisdictions, we must receive approval from the appropriate regulatory authorities before we can commercialize any 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 product candidates for sale outside the United States.

We might not obtain approval from the EMEA for Orphan Drug Status in the European Union

We are currently involved in the process of applying for orphan drug status for droxidopa in the European Union from the EMEA. The EMEA is authorized to grant orphan drug designation for a drug intended to treat a rare disease or condition, which generally is a disease or condition that affects fewer than five persons in 10,000 within the countries of the European Union. Although there are other opportunities for market exclusivity in the European Union, if the EMEA does not grant orphan status for droxidopa it is likely to extend both the time and the cost of our clinical trials, or require us to have separate and more extensive trials for droxidopa in Europe. We can provide no assurance that we will have adequate resources to conduct these additional trials or that they will ultimately result in regulatory approval in Europe.

Our drug candidates may require extensive reformulation work prior to approval or they may prove unsuitable for further development regardless of reformulation efforts.

Our development program for CH-1504 was delayed in May of 2006 as a result of data that came to our attention concerning possible bioavailability issues and animal data suggesting significant variations in blood plasma levels. We have identified possible improvements to the formulation for CH-1504 that we believe will improve the drug relative to these issues, however we cannot determine at this time whether these improvements will be adequate to justify further clinical trials or ultimately to permit FDA and other regulatory approvals. Other formulation issues may arise or prove more significant than anticipated, either with CH-1504 or with other drug candidates in our portfolio.

19

Our product candidate CH-1504 has had only limited formal clinical trials.

Our product candidate, CH-1504, is in an early stage of development and requires extensive clinical testing. In June 2005, we commenced Phase I dose escalation clinical trials of CH-1504 in humans in the United Kingdom at Guy’s Hospital in London, under the Clinical Trial Authorization, or CTA, issued by the Medicines and Healthcare Products Regulatory Agency, the United Kingdom’s health authority. Following the current reformulation program, additional clinical testing will be required to ascertain equivalency ratios for the reformulated compound as compared to the compound used during the Phase I trials in the UK. Following this additional clinical testing we will determine whether safety and pharmacokinetic data will enable us to initiate Investigational New Drug (IND) submissions for CH-1504 in rheumatoid arthritis with the FDA, EMEA and other health agencies to initiate Phase II trials later this year. After the completion of those trials, we plan on initiating several additional Phase II studies (in other indications) and, as appropriate, Phase III studies in rheumatoid arthritis. Upon completion of the Phase III studies in rheumatoid arthritis, we hope to use data from these studies to file a New Drug Application, or NDA. We currently estimate a global filing of the NDA no sooner than 2010. However, we cannot predict with any certainty the timing of our clinical trials, if or when we might submit an NDA for regulatory approval of this product candidate or whether such an NDA will be accepted.

There has been only very limited testing of our I-3D product candidates.

Our I-3D product candidates being jointly developed with Active Biotech are early in their development. None of the candidates have had adequate toxicology testing in animals to permit clinical testing and there is no clinical evidence of efficacy for any of these candidates, despite limited similarities with compounds currently marketed by others. Animal toxicology trials on our I-3D compounds may not permit further development of these drugs or we may have to carry out toxicology trials on several compounds before we find one that is appropriate for clinical testing. Once clinical trials are undertaken, the compound or compounds may not prove adequately safe and efficacious in humans and may not be approved by the FDA or other regulatory agencies.

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 any product candidate will take at least two 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 might be delayed by several factors, including:

• unforeseen safety issues;

• clarification of dosing issues;

• lack of effectiveness during clinical trials;

• slower than expected rates of patient recruitment;

• inability to monitor patients adequately during or after treatment;

• inability or unwillingness of medical investigators to follow our clinical protocols; and

• unexpected emergence of competitive drugs against which our compounds might need to be tested.

In addition, we or the FDA or another governing regulatory agency may suspend our clinical trials at any time if it appears that we are exposing participants to unacceptable health risks or if the regulatory agency finds deficiencies in the conduct of these or our regulatory submissions. Therefore, we cannot predict with any certainty the schedule for future clinical trials.

20

The results of our clinical trials might not support our product candidate claims.

Even if our clinical trials are completed as planned, we cannot be certain that their results will support our product 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 might fail to demonstrate that our product candidates are safe for humans and effective for indicated uses. This failure would cause us to abandon a product candidate and might delay development of other product candidates. Any delay in, or termination of, our clinical trials will delay the filing of our NDAs with the FDA and, ultimately, our ability to commercialize our product candidates and generate product revenue. Preliminary clinical trials conducted previously on our CH-1504 compound involved a small patient population over a relatively short period and because of these factors, the results might not be indicative of future results. Moreover, these initial trials were not performed in accordance with standards normally required by the FDA and other regulatory agencies.

We intend to explore additional indications for droxidopa, however these programs may not prove successful.

We have announced our interest in exploring certain additional indications for droxidopa and we may make similar announcements in the future. While trials conducted by our partner, Dainippon Sumitomo Pharma Co., Ltd. (DSP), for the Japanese market provide evidence of efficacy for certain indications, other indications may be explored for which we have no existing clinical evidence of efficacy. Such trials are likely to be very costly. We do not have market approval from the FDA or other regulatory agencies for any of the indications we are exploring and there are no guarantees that additional clinical trials will provide new evidence of efficacy in the targeted indications or permit us to gain market approval from regulatory agencies.

Physicians and patients might not accept and use our drugs.

Even if the FDA approves any of our product candidates, physicians and patients might not accept and use them. Acceptance and use of our products will depend upon a number of factors including:

• perceptions by members of the healthcare community, including physicians, about the safety and effectiveness of our drug;

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

• understanding by prescribing physicians of the medical conditions we are attempting to address;

• availability of reimbursement for our product from government or other healthcare payers; and

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

Because we expect that sales of our product candidates could, if approved, generate a substantial portion of our product revenue for an extended period, the failure of such a drug to find market acceptance would harm our business and could require us to seek additional financing.

Our drug development program depends upon third-party researchers who are outside our control.

We depend upon independent investigators and collaborators, such as universities and medical institutions, to conduct our pre-clinical and clinical trials under agreements with us. These collaborators are not our employees and we cannot control the amount or timing of resources that they devote to our programs. These investigators might not assign as great a priority to our programs or pursue them as diligently as we would if we were undertaking such programs ourselves. If outside collaborators fail to devote sufficient time and resources to our drug-development programs, or if their performance is substandard, the approval of our FDA applications, if any, and our introduction of new drugs, if any, will be delayed. These collaborators might also have relationships with other commercial entities, some of which might compete with us. If our collaborators assist our competitors at our expense, our competitive position would be harmed.

21

Our drug development program also depends upon our partners who are outside our control.

We have licensed certain rights related to droxidopa from Dainippon Sumitomo Pharma Co., Ltd. (DSP) and depend upon them for data and support in advancing our clinical program for this compound. In addition, DSP is currently the sole manufacturer of this compound for our clinical program. Similarly, we are pursuing the development of the I-3D portfolio with our partner, Active Biotech AB and depend on their cooperation to advance the program and to share the cost of development and testing. Without the timely support of these partners, either program could suffer significant delays, require significantly higher spending or face cancellation.

We rely exclusively on third parties to formulate and manufacture any product candidates.

We have no experience in drug formulation or manufacturing and do not intend to establish our own manufacturing facilities. We lack the resources and expertise to formulate or manufacture our own product candidates. While we have a contract in place with DSP covering droxidopa, we currently have no contract for the commercial scale manufacture of CH-1504 or other antifolate or I-3D compounds. We intend to contract with one or more manufacturers to manufacture, supply, store and distribute drug supplies for our clinical trials. If any of our current product candidates or any other product candidates that we may develop or acquire in the future receive FDA approval, we will rely on one or more third-party contractors to manufacture our drugs. Our anticipated future reliance on a limited number of third-party manufacturers exposes us to the following risks:

• We might not be able 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, 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, if any.

• Our future contract manufacturers might not perform as agreed or might 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 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.

Each of these risks could delay our clinical trials, the approval, if any, of our product candidates by the FDA or the commercialization of our product candidates or result in higher costs or deprive us of potential product revenue.

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

We currently have no sales, marketing or distribution capabilities other than as provided by the recent hiring of our Vice President of Sales and Marketing. We do not anticipate having significant additional resources within the next 12 months to allocate to the sales and marketing of our proposed products. As a result, our future success depends, in part, on:

• our ability to enter into and maintain collaborative relationships for these capabilities, either through out-licensing of our compounds or through contracting organizations;

• the collaborator’s strategic interest in the products under development; and

• such collaborator’s ability to successfully market and/or sell any such products.

22

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 or if we decide to add internal resources to complement third party resources, significant development expenditures, management resources and time will be required to establish and develop our own marketing and sales force with technical expertise.

If we cannot compete successfully for market share against other drug companies, we will not achieve sufficient product revenue and our business will suffer.

The market for our product candidate CH-1504 is characterized by intense competition and rapid technological advances. The identified market for droxidopa, while smaller, has well established generic competition. If CH-1504, droxidopa or other product candidates receive FDA approval, they will compete with a number of existing and future drugs and therapies developed, manufactured and marketed by others. Existing or future competing products might provide greater therapeutic convenience, efficacy or other benefits for a specific indication than our products, or might offer comparable performance at a lower cost. If our products fail to capture and maintain market share, we will not achieve sufficient product revenue and our business will suffer.

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. Many of these competitors have compounds already approved or in development. 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 significantly greater experience in:

• developing drugs;

• undertaking pre-clinical testing and human clinical trials;

• obtaining FDA and other regulatory approvals of drugs;

• formulating and manufacturing drugs;

• launching, marketing and selling drugs; and

• post-marketing safety surveillance.

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

Companies that currently sell both generic and proprietary compounds for the treatment of rheumatoid arthritis include but are not limited to Abbott Laboratories, Amgen, Aventis, Barr Laboratories, Boehringer Ingelheim Pharma, Hoffman—La Roche, Johnson & Johnson, Bristol-Myers Squibb and Mylan Laboratories. Companies that currently sell compounds used for the treatment of orthostatic hypotension include Shire, Mylan Pharmaceuticals, Eon Labs, Impax Laboratories and King Pharmaceuticals. Alternative technologies are being developed to treat rheumatoid arthritis by numerous companies including Celltech, which are in advanced clinical trials. See “Description of Business—Competition”. In addition, companies pursuing different but related fields represent substantial competition. Many of these organizations competing with us 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 and parties for acquisitions, joint ventures or other collaborations.

23

Our success, competitive position and future revenue will depend in part on our ability 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 do not know whether any of our pending patent applications or those patent applications that we may file or license in the future will result in the issuance of any patents. Moreover, we cannot predict the degree of patent protection that will be afforded by those patent applications that do result in issuance. Although we generally seek the broadest patent protection available for our proprietary compounds, we may not be able to obtain patent protection for the actual composition of any particular compound and may be limited to protecting a new method of use for the compound or otherwise restricted in our ability to prevent others from exploiting the compound. If our patent protection for any particular compound is limited to a particular method of use or indication such that, if a third party were to obtain approval of the compound for use in another indication, we could be subject to competition arising from off-label use.

Moreover, our issued patents and those that may issue in the future, or those licensed to us, may be challenged, invalidated, rendered unenforceable or circumvented, any of which could limit our ability to stop competitors from marketing related products. In addition, the rights granted under any issued patents may not provide us with competitive advantages against competitors with similar compounds or technologies. Furthermore, our competitors may independently develop similar technologies in a manner that does not infringe our patents or other intellectual property.

If a third party legally challenges our patents or other intellectual property rights that we own or license, we could lose certain of these rights. For example, third parties may challenge the validity of our U.S. or foreign patents through reexaminations, oppositions or other legal proceedings. If successful, a challenge to our patents or other intellectual property rights could deprive us of competitive advantages and permit our competitors to use our technology to develop similar products.

In addition, we do not anticipate having patent protection on our droxidopa compound if it receives market approval by the FDA. While the orphan drug designation for this compound by the FDA will provide seven (7) years of market exclusivity, we will not be able to exclude other companies from manufacturing and marketing this compound beyond that timeframe.

Claims by third parties that we infringe their proprietary rights may result in liability for damages or prevent or delay our developmental and commercialization efforts.

If a third party were to file a patent infringement suit against us, we could be forced to stop or delay research, development, manufacturing or sales of any infringing product in the country or countries covered by the patent infringed, unless we can obtain a license from the patent holder. Any necessary license may not be available on acceptable terms or at all, particularly if the third party is developing or marketing a product competitive with the infringing product. Even if we are able to obtain a license, the rights may be nonexclusive, which would give our competitors access to the same intellectual property. We also may be required to pay substantial damages to the patent holder in the event of an infringement. If we have supplied infringing products to third parties for marketing or have licensed third parties to manufacture, use or market infringing products, we may be obligated to indemnify these third parties for any damages they may be required to pay to the patent holder and for any losses they may sustain themselves as a result.

We may initiate patent litigation against third parties to protect or enforce our patent rights. Failure to protect our patents and other proprietary rights may materially harm our business, financial condition and results of operations.

Legal or administrative proceedings may be necessary to defend against claims of infringement or to enforce our intellectual property rights. If we become involved in any such proceeding, irrespective of the outcome, we may incur substantial costs, and the efforts of our technical and management personnel may be

24

diverted, which could materially harm our business. Furthermore, because of the substantial amount of discovery required in connection with intellectual property litigation, there is a risk that disclosure of some of our confidential information could be compelled and the information compromised. In addition, during the course of this kind of litigation, there could be public announcements of the results of hearings, motions or other interim proceedings or developments that, if perceived as negative by securities analysts or investors, could have a substantial adverse effect on the trading price of our common stock.

Existing patents and proprietary rights could harm our competitive position.

Other entities may have or obtain patents or proprietary rights that could limit our ability to manufacture, use, sell, offer for sale or import products or impair our competitive position. In addition, to the extent that a third party develops new technology that covers our products, we may be required to obtain licenses to that technology, which licenses may not be available or may not be available on commercially reasonable terms, if at all. Our failure to obtain a license to any technology that we require may materially harm our business, financial condition and results of operations.

Changes in either patent laws or in interpretations of patent laws in the United States and other countries may diminish the value of our intellectual property or narrow the scope of our patent protection.

The laws of foreign countries may not protect our rights to the same extent as the laws of the United States. Therefore, enforceability or scope of our patents in the United States or in foreign countries cannot be predicted with certainty, and, as a result, any patents that we own or license may not provide sufficient protection against competitors.

Some jurisdictions have laws that permit the government to force a patentee to grant a license to a third party for commercialization of a patented product if the government concludes that the product is not sufficiently developed or not meeting the health needs of the population. Such compulsory licensing laws are very rarely invoked outside of South America and Africa. In addition, a number of countries limit the enforceability of patents against government agencies or government contractors. In these countries, the patent owner may be limited to monetary relief and may be unable to enjoin infringement, which could materially diminish the value of the patent. Such compulsory licenses could be extended to include some of our product candidates, which may limit our potential revenue opportunities.

Because of the extensive time required for development, testing and regulatory review of a new drug, it is possible that any related patent may expire before any of our product candidates can be commercialized or remain in force for only a short period following commercialization. In either case, this would reduce any advantages of the patent.

If we are unable to satisfy our obligations under current and future license agreements, we could lose license rights which would adversely affect our business.

We are a party to a license agreement with M. Gopal Nair under which we license patent rights for our product candidate CH-1504. Similarly, we license patent and/or certain other rights from Dainippon Sumitomo Pharma Co., Ltd. (DSP) for droxidopa and from Active Biotech AB for the I-3D portfolio of compounds. We may enter into additional licenses in the future. Our existing licenses impose, and we expect future licenses will impose, various milestone payments, royalty payments and other obligations on us. If we fail to comply with our obligations in our intellectual property licenses with third parties, we could lose license rights that are important to our business. If a licensor challenges our license position, our competitive position and business prospects could be harmed.

Our license agreement with Dr. Nair reserves rights to the licensor in India. Therefore, we will not commercialize CH-1504 in India. Our license agreement with DSP reserves rights to the licensor in Japan, Korea,

25

China and Taiwan which preclude our commercialization of droxidopa in those markets. Our license agreement with Active Biotech AB grants rights to us only in North America and South America with Active Biotech retaining commercialization rights in the rest of the world.

If we are unable to enforce trade secret protection and confidentiality agreement with our employees, our competitive position might be harmed.

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 are unobtainable or difficult to obtain, we rely on trade secret protection and confidentiality agreements. To this end, it is our policy to require all of our employees, consultants, advisors and contractors 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 might 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, 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 we might have to:

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

• abandon an infringing drug candidate;

• redesign our products or processes to avoid infringement;

• stop using the subject matter claimed in the patents held by others;

• pay damages; or

• defend litigation or administrative proceedings, which might be costly whether we win or lose, and which could result in a substantial diversion of valuable management resources.

Our ability to generate product revenue will be diminished if our drugs sell for inadequate prices or patients are unable to obtain adequate levels of reimbursement.

Our ability to commercialize our drugs, alone or with collaborators, will depend in part on the extent to which reimbursement will be available from:

• government and health administration authorities;

• private health maintenance organizations and health insurers; and

• other healthcare payers.

Significant uncertainty exists as to the reimbursement status of newly approved healthcare products. Healthcare payers, including Medicare, are challenging the prices charged for medical products and services. Government and other healthcare payers increasingly attempt to contain healthcare costs by limiting both coverage and the level of reimbursement for drugs. Even if a product candidate is approved by the FDA, insurance coverage might not be available and reimbursement levels might be inadequate to cover our drug. If government and other healthcare payers do not provide adequate coverage and reimbursement levels for our product, once approved, market acceptance and our revenue could be reduced.

26

Specifically, not all physicians recognize a separate indication for symptomatic neurogenic orthostatic hypotension and we cannot provide assurances that reimbursement will be approved by the relevant decision makers even if droxidopa receives market approval from the FDA or other regulatory authorities.

We might not successfully manage our growth.

We are a small, development stage company. Our success will depend upon the expansion of our operations and the effective management of our growth, which will place a significant strain on our management and on our administrative, operational and financial resources. We currently have eleven (11) employees and anticipate hiring approximately four additional employees over the next 12 months. To manage this growth, we might have to expand our facilities, augment our operational, financial and management systems and hire and train additional qualified personnel. If we are unable to manage our growth effectively, our business would be harmed.

We might be exposed to liability claims associated with the use of hazardous materials and chemicals.

Our research and development activities might involve the controlled use of hazardous materials and chemicals. Although we believe that our safety procedures, and those of our partners, for using, storing, handling and disposing of these materials comply with federal, state, local and, where applicable, foreign laws and regulations, we cannot completely eliminate the risk of accidental injury or contamination from these materials. In the event of such an accident, we could be held liable for any resulting damages and any liability could materially adversely affect our business, financial condition and results of operations. In addition, the laws and regulations governing the use, manufacture, storage, handling and disposal of hazardous or radioactive materials and waste products might require us to incur substantial compliance costs that could materially adversely affect our business, financial condition and results of operations.

We rely on key executive officers and scientific and medical advisors, and their knowledge of our business and technical expertise would be difficult to replace.

As a small, development-stage company, we are highly dependent on our executive officers, including particularly our Chief Executive Officer, Simon Pedder, Ph.D., and our principal scientific, regulatory and medical advisors. Dr. Pedder is the only executive officer whose employment with us is governed by an employment agreement, and the term of employment under that agreement expires in May 2009. We do not have “key person” life insurance policies for any of our officers. The loss of the technical knowledge and management and industry expertise of any of our key personnel could result in delays in product development, loss of customers and sales and diversion of management resources, which could adversely affect our operating results.

If we are unable to hire additional qualified personnel, our ability to grow our business will be harmed.

As a small, development stage company, we will need to hire additional qualified personnel with expertise in pre-clinical testing, clinical research and testing, government regulation, formulation and manufacturing and sales and marketing. We compete for qualified individuals with numerous pharmaceutical and biopharmaceutical companies, universities and other research institutions. Competition for such individuals is intense, and we cannot be certain that our search for such personnel will be successful. Attracting and retaining qualified personnel is critical to our success.

We might incur substantial liabilities and might 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 might 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

27

of our products. Although we carry clinical trial insurance, we might not be able to renew such insurance at a reasonable cost, if at all, or our intended collaborators may be unable to obtain such insurance at a reasonable cost, if at all. Even if our agreements with any future collaborators entitle us to indemnification against losses, that indemnification might not be available or adequate should any claim arise.

The trading volume of our common stock is limited and our investors may encounter difficulties selling significant quantities of our stock without adversely impacting the price at which they can sell.

Since listing with the NASDAQ Stock Market in May of 2006 the trading volume for our stock has varied significantly from day to day and often the number of shares traded has been low. For example, from the commencement of trading on the NASDAQ Stock Market on May 2, 2006 through the end of the year, the trading volume of our stock was less than 10,000 shares on 82 of 169 trading days. No assurance can be given that a more liquid trading market will develop.

The prices at which are shares of our common stock are traded will likely be volatile.

You should expect the prices at which our common stock is traded to be highly volatile. For example, since the merger between Chelsea Therapeutics, Inc. and Ivory Capital on February 11, 2005, the trading price of our common stock has been as low as $2.43 and as high as $36.00. Even since the commencement of NASDAQ trading in May 2006, the price has varied from a low of $2.43 to a high of $7.30. The expected volatile price of our stock will make it difficult to predict the value of your investment, to sell your shares at a profit at any given time, or to plan purchases and sales in advance. A variety of other factors might also affect the market price of our common stock. These include, but are not limited to:

• publicity regarding actual or potential clinical results relating to products under development by our competitors or us;

• delays or failures in initiating, completing or analyzing pre-clinical or clinical trials or the unsatisfactory design or results of these trials;

• achievement or rejection of regulatory approvals by our competitors or us;

• announcements of technological innovations or new commercial products by our competitors or us;

• developments concerning proprietary rights, including patents;

• developments concerning our collaborations;

• regulatory developments in the United States and foreign countries;

• economic or other crises and other external factors;

• period-to-period fluctuations in our results of operations;

• changes in financial estimates by securities analysts; and

• sales of our common stock.

We will not be able to control many of these factors, and we believe that period-to-period comparisons of our financial results will not necessarily be indicative of our future performance.

In addition, the stock market in general, and the market for biotechnology companies in particular, has experienced extreme price and volume fluctuations that might have been unrelated or disproportionate to the operating performance of individual companies. These broad market and industry factors might seriously harm the market price of our common stock, regardless of our operating performance.

28

We have never paid dividends and do not intend to pay cash dividends.

We currently anticipate that no cash dividends will be paid on our common stock in the foreseeable future. While our dividend policy will be based on the operating results and capital needs of the business, it is anticipated that all earnings, if any, will be retained to finance our future operations.

ITEM 1B. UNRESOLVED STAFF COMMENTS

None.

ITEM 2. PROPERTIES

We lease 3,916 square feet of office space in Charlotte, North Carolina. This lease currently requires us to make monthly payments of approximately $4,757 through June 30, 2007 and monthly payments of approximately $4,901 through the expiration date. The lease expires June 30, 2008. We do not own any real property. We believe that our existing facilities are adequate to meet our needs in the near term although the need may arise for expanding our existing facilities within the next 12 to 18 months.

ITEM 3. LEGAL PROCEEDINGS

We are not subject to any pending legal proceeding, nor are we aware of any threatened claims against us.

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

No matters were submitted to a vote of our security holders during the fourth quarter of the year ended December 31, 2006.

ITEM 5. MARKET FOR THE REGISTRANTS COMMON EQUITY, RELATED STOCKHOLDER MATTERS AND ISSUER PURCHASES OF EQUITY SECURITIES

Our common stock has been traded on the National Association of Securities Dealers Automatic Quotation System (“NASDAQ”) under the symbol “CHTP” since May 2, 2006 and traded on the Over-the-Counter Bulletin Board under the symbol “CHTP.OB” from July 29, 2005 through May 1, 2006 and under the symbol “IVRC.OB” from August 18, 2004 through July 28, 2005. The following table sets forth the high and low bid and ask prices of our common stock, as reported per the appropriate market. These quotations reflect inter-dealer prices, without retail mark-up, markdown, or commission and may not represent actual transactions. Trading on our common stock has been sporadic, exemplified by low trading volume, with 82 of 169 trading days between our listing on NASDAQ and the end of 2006 having fewer than 10,000 shares traded. All prices reflect the 1-for-9 share exchange executed in connection with our Delaware reincorporation in July 2005.

As of March 8, 2007, the last sale price of our common stock on NASDAQ was $5.60 per share. As of March 8, 2007, there were approximately 623 stockholders of record.

We have neither paid nor declared dividends on our common stock since our inception and do not plan to pay dividends in the foreseeable future. Any earnings that we may realize will be returned to finance our growth.

The market prices for securities of biotechnology and pharmaceutical companies, including ours, have historically been highly volatile, and the market has from time to time experienced significant price and volume fluctuations that are unrelated to the operating performance of particular companies. Factors, such as fluctuations in our operating results, announcements of technological innovations or new therapeutic products by us or others, clinical trial results, developments concerning agreements with collaborators, governmental regulation, developments in patent or other proprietary rights, public concern as to the safety of drugs developed by us or others, future sales of substantial amounts of common stock by existing stockholders and general market conditions, can have an adverse effect on the market price of the common stock.

ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINCANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion of our financial condition and results of operations should be read in conjunction with the financial statements and the notes to those statements included elsewhere in this Annual Report on Form 10-K. This discussion contains predictions, estimates and other forward-looking statements that involve a number of risks and uncertainties, including those discussed under “Risk Factors” and elsewhere in this Annual Report on Form 10-K. These risks could cause our actual results to differ materially from those anticipated in these forward-looking statements.

Overview

Since inception we have focused primarily on organizing and staffing our company, negotiating in-licensing agreements with our partners, acquiring, developing and securing our proprietary technology, participating in regulatory discussions with the FDA, the EMEA and other regulatory agencies and undertaking pre-clinical trials and clinical trials of our product candidates. We are a development stage company and have generated no revenue since inception. We do not anticipate generating any revenue until and unless we successfully obtain approval from the FDA or equivalent foreign regulatory bodies to begin selling our pharmaceutical candidates. However, developing pharmaceutical products is a lengthy and expensive process. Even if we do not encounter unforeseen safety issues or timing or other delays during the course of developing our currently licensed product candidates, we would not anticipate receiving regulatory approval to market such products until at least 2009. Currently, development expenses are being funded with proceeds from private equity financings completed in December 2004 and February 2006. To the extent we are successful in acquiring additional product candidates for our development pipeline and as we move our products into more extensive clinical trials, our need to finance research and development costs will continue to increase. Accordingly, our success depends not only on the safety and efficacy of our product candidates, but also on our ability to finance the development of the products.

On February 11, 2005, we completed a merger with Ivory Capital Corporation, a publicly traded Colorado corporation, in which a wholly owned subsidiary of Ivory Capital was merged with and into Chelsea, and Chelsea became a wholly owned subsidiary of Ivory Capital. As a result of the merger, Ivory Capital, which previously had no material operations, acquired the business of Chelsea. Each outstanding share of common stock and Series A Preferred Stock of Chelsea was converted into approximately 10.56 shares of common stock of Ivory Capital and outstanding options and warrants to purchase either common stock or Series A Preferred Stock of Chelsea were assumed by Ivory Capital and converted into options and warrants to purchase shares of common stock at the same ratio. The merger resulted in a change of control of Ivory Capital, with the former stockholders of Chelsea owning approximately 96.75% assuming the conversion of all outstanding options and warrants.

In addition, the terms of the merger provided that the sole officer and director of Ivory Capital would be replaced by the officers and directors of Chelsea. Further, having had no significant business activity for a number of years, upon the effective time of the merger, Ivory Capital adopted the business plan of Chelsea. The transaction was therefore accounted for as a reverse acquisition with Chelsea as the acquiring party and Ivory Capital as the acquired party, in substance, a reorganization of Chelsea. Accordingly, when we refer to our business and financial information relating to periods prior to the merger, we are referring to the business and financial information of Chelsea unless the context indicates otherwise.

On June 17, 2005, Ivory Capital Corporation formed a wholly owned subsidiary in Delaware named Chelsea Therapeutics International, Ltd. for the purposes of reincorporating in Delaware. On July 28, 2005, Ivory Capital Corporation merged with Chelsea Therapeutics International, Ltd., with Chelsea Therapeutics International, Ltd. as the surviving corporation. As a result, Chelsea Therapeutics International, Ltd. is the public reporting company and is the 100% owner of Chelsea Therapeutics, Inc., its operating subsidiary.

32

When we refer to business and financial information for periods between January 1, 2005 and July 28, 2005, we are referring to the business and financial information of Ivory Capital Corporation. Except as noted, all share numbers included herein reflect the conversion of every nine shares of Ivory Capital Corporation common stock for one share of Chelsea Therapeutics International, Ltd. common stock that occurred in connection with our Delaware reincorporation on July 28, 2005.

Revenue and Cost of Revenue

We have not generated any revenue from licensing, milestones or product sales through December 31, 2006, and we do not expect to generate revenue within the next 12 to 24 months. We might never be able to generate revenue. None of our existing product candidates are expected to be commercially available until 2009, if at all.

Research and Development

Research and development expenses consist primarily of costs associated with determining feasibility, licensing and pre-clinical and clinical testing of our licensed pharmaceutical candidates, including salaries and related personnel costs, fees paid to consultants and outside service providers for drug manufacture and development, certain legal expenses and other expenses.

Sales and Marketing

Selling and marketing expenses consist primarily of salaries and related expenses that support our business development activity, promotional expenses, expenses related to the branding of our pharmaceutical compounds and certain legal expenses.

General and Administrative

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

Critical Accounting Policies

Our management’s discussion and analysis of our financial condition and results of operations is based on our financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America. Our significant accounting policies are more fully described in Note 1 to the financial statements accompanying this Annual Report on Form 10-K. The following accounting policies are critical in fully understanding and evaluating our reported financial results.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent liabilities at the date of the financial statements as well as the reported revenue and expenses during the reporting periods. On an ongoing basis, management evaluates its estimates and judgments. Management bases estimates on historical experience and on various other factors that it believes are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results might differ from these estimates under different assumptions or conditions.

33

Research and Development

Research and development expenditures are expensed as incurred. We often contract with third parties to facilitate, coordinate and perform agreed upon research and development activities. To ensure that research and development costs are expensed as incurred, we measure expense based on work performed for the underlying contract, typically utilizing a percentage-of-completion approach, and record prepaid assets or accrue expenses on a monthly basis for such activities based on the measurement of liability from expense recognition and the receipt of invoices.

These contracts typically call for the payment of fees for services at the initiation of the contract and/or upon the achievement of certain milestones. In the event that we prepay fees for future milestones, we record the prepayment as a prepaid asset and amortize the asset into research and development expense over the period of time the contracted research and development services are performed. Most fees are incurred throughout the contract period and are expensed based on their percentage of completion at a particular date.

These contracts generally include pass through fees. Pass through fees include, but are not limited to, regulatory expenses, investigator fees, travel costs, and other miscellaneous costs including shipping and printing fees. Because these fees are incurred at various times during the contract term and they are used throughout the contract term, we record a monthly expense allocation to recognize the fees during the contract period. Fees incurred to set up the clinical trial are expensed during the setup period.

Costs related to the acquisition of technology rights and patents for which development work is still in process are expensed as incurred and considered a component of research and development costs.

Accounting for Stock-Based Compensation

We account for our employee stock options and warrants using the fair value method as prescribed in Statement of Financial Accounting Standards No. 123R (“SFAS 123R”), Share-based Payment. SFAS 123R defines a fair value based method of accounting for employee stock options or similar equity instruments. In determining the fair value of the equity instrument, we considered, among other factors, (i) the risk-free interest rate, (ii) the expected life of the options granted, (iii) the anticipated dividend yield, (iv) the estimated future volatility of the underlying equity and (v) anticipated future forfeitures. To determine the risk-free interest rate, the Company utilized the U.S. Treasury yield curve in effect at the time of grant with a term consistent with the expected term of the Company’s awards. The Company estimated the expected life of the options granted based on anticipated exercises in future periods assuming the success of its business model as currently forecasted. The expected dividends reflect the Company’s current and expected future policy for dividends on its common stock. To determine the expected stock price volatility for the Company’s stock options, the Company examined historical volatilities for industry peers as the Company did not have sufficient trading history for its common stock. The Company will continue to analyze the expected stock price volatility and expected term assumption as more historical data for the Company’s common stock becomes available. Given the limited service period for its current employees and the senior nature of the roles for those employees, the Company currently estimates that it will experience no forfeitures for those options currently outstanding. Our results include non-cash compensation expense as a result of the issuance of stock option grants utilizing this method. We expect to record additional non-cash compensation expense in the future, which might be significant, particularly if our stock price increases. Due to the limited amount of historical data available to us, particularly with respect to stock-price volatility, employee exercise patterns and forfeitures, actual results could differ from our assumptions.

Results of Operations

The tables below set forth, for the periods indicated, certain items in the Company’s consolidated statements of income and other pertinent financial and operating data.

Comparison of Years ended December 31, 2006 and 2005

(in thousands, except percentages)	For the Year ended December 31, 2006		For the Year ended December 31, 2005		$ Increase (Decrease)			% Change
Research and development expense	$	6,864	$	5,516	$	1,348		24	%
Sales and marketing expense		642		525		117		22	%
General and administrative expense		2,028		2,076		(48	)	-2	%
Interest income		863		200		663		332	%

Research and development expenses for each period consisted primarily of expenses incurred for compensation and related expenses and amounts paid to outside contract manufacturing and contract research organizations relating to our product candidates. As a percentage of operating expenses, research and development costs increased from 68% for 2005 to 72% for 2006. During 2006, we continued our manufacturing, pre-clinical, Phase I and Phase II activities for CH-1504 and initiated manufacturing and pre-clinical activities for additional antifolates, droxidopa and a portfolio of therapeutics in partnership with Active Biotech. We also incurred additional licensing costs for CH-1504 and initial licensing costs for droxidopa. During 2006 such expenses were approximately $5.1 million, an increase of approximately $0.9 million when compared to similar expenses for the year ended December 31, 2005. Also contributing to the increase in research and development costs were a $0.1 million increase in compensation and related expenses, a $0.2 million increase in general contractor and outside services expense and a $0.1 million increase in travel costs.

Sales and marketing expenses. We had no formalized selling activities for the year ended December 31, 2006. Sales and marketing expenses are primarily the costs of business development activity and, during 2006, expenses incurred in the initiation and development of marketing and branding programs for droxidopa. Such costs include compensation and related costs, promotional activities, contractor expenses and certain legal expenses. The increase is primarily related to compensation and related expenses, contractor expenses and travel costs.

General and administrative expenses. General and administrative costs focus on support of administrative activities and consisted primarily of compensation and related expenses, consulting and professional fees, travel costs, insurance and facility expenses. Contributing to the decrease in these costs were a $0.1 million decrease in investor relations expenses, primarily related to the hiring of a former third-party contractor, a $0.1 million decrease in accounting fees and a $0.1 million decrease in legal fees, offset by a $0.2 million increase in compensation and related expenses and a $0.1 million increase in travel costs.

Interest income. Our cash position in 2006 reflects the proceeds of approximately $21.5 million received from the 2006 Placement. Accordingly, interest earned on short-term, cash equivalent, liquid investments from cash on deposit increased during 2006.

35

Research and development expenses for each period consisted primarily of expenses incurred for compensation and related expenses and amounts paid to outside contract manufacturing and contract research organizations relating to our product candidates and totaled 68% of total operating expenses for 2005 and 61% for 2004. During 2005, we carried out significant manufacturing, pre-clinical and phase I activities for CH-1504, generating expenses of approximately $4.1 million, an increase of $3.0 million when compared to similar expenses for the year ended December 31, 2004. Also contributing to the increase in research and development costs was an increase of $0.7 million in compensation and related expenses for employees hired during 2004 and early 2005.

Sales and marketing expenses. Although we had no formalized selling activities for the year ended December 31, 2005, we did incur expenses totaling approximately $0.5 million. These expenses related primarily to business development activity, including compensation and related costs, relocation costs, promotional activities, contractor expenses and certain legal expenses. We incurred sales and marketing expenses for the year ended December 31, 2004 of $0.2 million for expenses of a similar nature, limited due to a partial year of activity.

General and administrative expenses focus on support of administrative activities and consisted primarily of compensation and related expenses, consulting and professional fees, travel costs, insurance and facility expenses. A significant factor contributing to the increase was a $0.4 million increase in compensation and related expenses primarily related to a partial year of operations in 2004 versus a full year of operations in 2005. In addition, there was a $0.2 million increase in investor relations expenses, primarily expenses paid to a third-party contractor, a $0.2 million increase in accounting expenses, including auditing fees, tax preparation costs and contractor expenses and a $0.2 million increase in legal fees.

Interest income. For the year ended December 31, 2005, we earned and recorded net interest income of approximately $0.2 million. Interest income consisted of interest earned on short-term, liquid investments made by us from cash on deposit. For the year ended December 31, 2004, we recorded net interest expense of approximately $28,000 consisting of interest charged on a loan from an affiliate that was repaid at the end of 2004.

Liquidity and Capital Resources

From inception to December 31, 2006, we have incurred an aggregate net loss of approximately $19.6 million as a result of expenses similar in nature to those described above.

We have financed our operations since inception primarily through equity and debt financing. As of December 31, 2006, we had working capital of approximately $14.1 million and cash and cash equivalents of approximately $15.9 million. Cash on hand results from net proceeds from financing activities in December 2004 and February 2006, offset by funds utilized for operating activities. Our financing activities are more fully described in “Financings” below.

We have incurred negative cash flows from operations since inception. 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 continuing efforts to secure in-licensing opportunities. Our continued operations will depend on whether we are able to raise additional funds through various potential sources, such as equity and debt financing. Such additional funds might not become available on acceptable terms, or at all, and there can be no assurance that any additional funding that we do obtain will be sufficient to meet our needs in the long term. From inception through December 31, 2006 we had losses of $19.6 million, and we anticipate losses in the range of $20 to 30 million during the 12 to 18 months commencing January 2007.

Actual losses will depend on a number of considerations, including:

• the pace and success of pre-clinical development and clinical trials for our droxidopa, CH-1504 and other product candidates;

36

• seeking regulatory approval for our product candidates;

• obtaining European Orphan Drug approval for droxidopa from the EMEA;

• discussions with regulatory agencies concerning the design of our clinical trials;

• possible out-licensing of certain of our product candidates;

• in-licensing and development of additional product candidates;

• implementing additional internal systems and infrastructure; and

• hiring additional personnel.

Financings

On February 13, 2006, we raised gross proceeds of approximately $21.5 million through the sale of 7,166,666 shares of our $0.0001 par value common stock plus warrants for the purchase of 2,149,999 shares of our $0.0001 par value common stock. The warrants permit the holders to purchase the underlying common shares at $4.20 each and are redeemable at our option in the event that the volume weighted average closing bid price of our common stock for any twenty (20) consecutive trading days is at least $9.00 per share. In connection with this offering, we engaged Paramount BioCapital, Inc. as placement agent and paid commissions and other offering-related expenses of approximately $1.6 million in cash and warrants to purchase 716,666 shares of our common stock with an exercise price of $3.30 per share, or 110% of the price of the shares sold in the offering and a fair value of approximately $0.98 per share. Under the terms of the financing we filed a registration statement with the SEC within 30 days of the closing for the shares of common stock sold and the shares of common stock underlying the warrants and such registration became effective on March 29, 2006.

In December 2004, we raised gross proceeds of approximately $14.5 million through the sale of 5,532,994 shares of our $0.0001 par value common stock. The amount raised included the conversion of a $1.7 million stockholder loan along with accrued interest, for which a total of 677,919 shares of common stock were issued. In connection with this offering, we engaged Paramount BioCapital, Inc. as placement agent and paid commissions and other offering-related expenses of approximately $1.0 million in cash and warrants to purchase 483,701 shares of our common stock with a fair value of approximately $0.03 per share.

License Agreement and Development Agreement Obligations

In March 2004, we entered into a License Agreement with Dr. M. Gopal Nair, Ph.D., of the University of South Alabama College of Medicine, for rights to use, produce, distribute and market products derived from an invention by Dr. Nair, claimed in US Patent # 5,912,251, entitled “metabolically inert anti-inflammatory and antitumor antifolates”, designated by us as CH-1504 and related compounds. The license provides us exclusive, worldwide (excluding India) rights for CH-1504.

In 2004, as consideration for these rights, we paid $150,000 and issued Dr. Nair and his designees 471,816 shares of common stock at an estimated aggregate value of $402. As additional consideration, we agreed to pay to Dr. Nair and or his designees (1) royalties on the sales should any compounds be approved for commercial sale; (2) milestone payments, payable upon achievement of clinical milestones; and (3) payments to be made on specified anniversary dates, some of which may be payable in equity, at our discretion, through 2009. During 2006 and 2005, we made additional payments to Dr. Nair under the agreement of $100,000 per year. At December 31, 2006, remaining future milestone and anniversary payments, which are subject to our rights to terminate the license agreement, totaled approximately $2,050,000.

The license agreement includes certain other covenants, which require us to, among other things, maintain and prosecute patents related to the license; use commercially reasonable best efforts to bring the licensed product to market as soon as reasonably practicable and continue active, diligent marketing efforts; and prepare and provide to the licensors certain reports concerning our development and commercialization efforts. In the

37

event we fail to carry out our responsibilities under the license agreement, the licensors may terminate the license. We may elect to abandon the maintenance and prosecution of any patent applications or issued patents and we retain the right to terminate the license agreement in whole or as to any portion by providing written notice of such intentions to the licensor. The license agreement may also be terminated in the event we fail to make a scheduled milestone or royalty payment, we otherwise materially breach the license agreement, or if we become involved in a bankruptcy, insolvency or similar proceeding, provided that we are entitled to notice of such intention to terminate and an opportunity to cure. Regardless, the license agreement shall expire concurrent with the date of the last to expire claim contained in the patent rights.

In May 2006, we entered into an agreement with Dainippon Sumitomo Pharma Co., Ltd. (DSP) for a worldwide, exclusive, sub-licensable license and rights to certain intellectual property and proprietary information relating to droxidopa including, but not limited to all information, formulations, materials, data, drawings, sketches, designs, testing and test results, records and regulatory documentation. As consideration for these rights, we paid DSP $100,000 and issued 63,131 shares of our $0.0001 par value common stock, with a value of approximately $4.35 per share, or $274,621. As additional consideration, we agreed to pay DSP and or its designees (1) royalties on the sales should any compound be approved for commercial sale; and (2) milestone payments, payable upon achievement of milestones as defined in the agreement. At December 31, 2006, remaining future milestone payments, subject to our right to terminate the license agreement, totaled $4.0 million, some of which may be payable in equity. Subsequent to execution of the agreement, we agreed that DSP will initiate, and we will fund, activities focused on modifying the manufacturing capabilities of DSP in order to expand capacity and comply with cGMP regulations and all existing manufacturing requirements of the FDA. Such activities are currently ongoing and shall continue over a two-year period.

In January 2007, we received notification that the FDA had granted orphan drug designation for droxidopa for the treatment of symptomatic neurogenic orthostatic hypotension. Based on the terms of the DSP agreement, the granting of orphan drug designation for droxidopa triggered a milestone payment to DSP of $250,000. We made such payment in February 2007. As of the date of that payment, remaining future milestone payments totaled $3.75 million.

In May 2006, we entered into a development and commercialization agreement with Active Biotech AB to co-develop and commercialize the I-3D portfolio of orally active, dihydroorotate dehydrogenase (DHODH) inhibiting compounds for the treatment of autoimmune diseases and transplant rejection. Under the terms of the license and co-development agreement, an initial payment of $1.0 million was made to Active Biotech during the quarter ended June 30, 2006 with such funds to be utilized to cover the initial costs of research and development efforts jointly approved by both parties. At December 31, 2006 we had expensed the entire $1.0 million payment and had expensed additional costs of $0.3 million under the program related to costs of research and development. Subsequent clinical development efforts will be jointly conducted and funded by both parties via a Joint Development Committee with equal representation from both parties. The agreement also provides us with the exclusive North and South American commercial rights to all drugs within this portfolio, while Active Biotech will retain rights for the remaining global markets. In addition to sharing development costs, both parties will pay royalty payments to the other on sales in their respective markets. Active Biotech will also receive certain defined milestone payments related to clinical development and receipt of revenue from commercialization of the compounds. Unless terminated by either party with six months written notice, the agreement shall remain in effect until the earlier of (1) the expiration of the last to expire patent rights indicated under the agreement or (2) fifteen (15) years from the date of the first commercial sale of the product. As of December 31, 2006, remaining future milestone payments, subject to our right to terminate the agreement, totaled $15.5 million.

Current and Future Financing Needs

We have incurred negative cash flow from operations since inception. 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

38

resources at December 31, 2006 and our projection of spending needs during 2007, we expect that we will want to secure additional financing during 2007 to support our planned operational activities.

However, the actual amount of funds we will need to operate is subject to many factors, some of which might be beyond our control. These factors include the following:

• the progress of our research activities;

• the number and scope of our research programs;

• the progress of our pre-clinical and clinical development activities;

• the progress of the development efforts of parties with whom we have entered into research and development agreements;

• our ability to maintain current research and development programs and to establish new research and development and licensing arrangements;

• our ability to achieve our milestones under licensing arrangements;

• opportunities to sub-license our existing compounds to others;

• potential acquisitions of other compounds or companies;

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

• the costs and timing of regulatory approvals.

We have based our estimate on assumptions that might prove to be incorrect. Potential sources of financing include strategic relationships, public or private sales of equity or debt and other sources. We might seek to access the public or private equity markets when and if conditions are favorable due to our long-term capital requirements. We do not have any committed sources of financing at this time, and it is uncertain whether additional funding will be available when we need it on terms that will be acceptable to us, or at all. If we raise funds by selling additional shares of common stock or other securities convertible into common stock, the ownership interest of our existing stockholders will be diluted. If we are not able to obtain financing when needed, we might be unable to carry out our business plan. As a result, we might have to significantly delay certain activities or limit our operations and our business, financial condition and results of operations would be materially harmed.

ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA

(a) The financial statements required to be filed pursuant to this Item 8 are appended to this Annual Report on Form 10-K. An index of the financial statements filed herewith is found on page 42.

(b) The unaudited quarterly financial data for the two-year period ended December 31, 2006 is as follows:

	Year ended December 31, 2005

Operating expenses	$	2,695,824		$	1,678,200		$	1,764,329		$	1,977,818
Loss from operations		(2,695,824	)		(1,678,200	)		(1,764,329	)		(1,977,818	)
Net loss		(2,638,517	)		(1,621,692	)		(1,715,075	)		(1,940,438	)

Basic and diluted loss per share (a)	$	(0.14	)	$	(0.09	)	$	(0.11	)	$	(0.12	)

(a) Basic and diluted loss per common share for each of the quarters presented above is based on the respective weighted average number of common shares for the quarters. As such, the sum of the quarters may not necessarily be equal to the full year loss per share amount. Basic and diluted loss per share are identical since potentially dilutive securities are excluded from the calculations, as the effect is anti-dilutive for all periods presented.

ITEM 9. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE

None.

ITEM 9A. CONTROLS AND PROCEDURES

(a) Disclosure controls and procedures (as defined in Exchange Act Rule 13a-15(e)) are designed only to provide reasonable assurance that they will meet their objectives. As of the end of the period covered by this report, we carried out an evaluation, under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of our disclosure controls and procedures (as defined in Rule 13a-15(e)) pursuant to Exchange Act Rule 13a-15. Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that our disclosure controls and procedures are effective.

(b) No change in our internal control over financial reporting occurred during our last fiscal quarter that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

As a result of the SEC’s deferral of the deadline for foreign and non-accelerated filers’ compliance with the internal control requirements of Section 404 of the Sarbanes-Oxley Act of 2002, as a non-accelerated filer we will not be subject to the requirements until our Annual Report on Form 10-K for fiscal year 2007.

Report of Independent Registered Public Accounting Firm

The Board of Directors and Stockholders

Chelsea Therapeutics International, Ltd.

We have audited the accompanying consolidated balance sheets of Chelsea Therapeutics, International, Ltd. and Subsidiary (A Development Stage Company) as of December 31, 2006 and 2005, and the related consolidated statements of operations, stockholders’ equity and cash flows for each of the three years in the period ended December 31, 2006 and the period from April 3, 2002 (inception) to December 31, 2006. These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits.

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

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of Chelsea Therapeutics International, Ltd. and Subsidiary (A Development Stage Company) as of December 31, 2006 and 2005, and their results of operations and cash flows for each of the three years in the period ended December 31, 2006 and the period from April 3, 2002 (inception) to December 31, 2006, in conformity with accounting principles generally accepted in the United States of America.

In addition, in conjunction with and as compensation for facilitating the merger, the Company issued warrants for the purchase of 105,516 shares of its $0.0001 par value common stock at an exercise price of $2.62 per share and an aggregate fair value of $26,700.

In December 2004, in conjunction with and as compensation for activities related to the December 2004 sale of equity securities, the Company issued warrants to purchase 483,701 shares of its $0.0001 par value common stock, with a purchase price of approximately $2.88 per share and an aggregate fair value of $14,400. In March 2006, 15,461 shares of the $0.0001 par value common stock of the Company were issued to holders upon exercise of warrants issued in December 2004 per the net share settlement provisions contained in the terms of the warrants.

In February 2006, in conjunction with and as compensation for activities related to the 2006 Placement (see Note 4), the Company issued warrants to purchase 716,666 shares of its $0.0001 par value common stock, with a purchase price of $3.30 per share and an aggregate fair value of approximately $705,000.

In May 2006, in conjunction with and as compensation for activities related to the licensing agreement with Dainippon Sumitomo Pharma Co., Ltd. and under a Finder’s Agreement, the Company issued warrants to purchase 250,000 shares of its $0.0001 par value common stock, with an exercise price of $4.31 per share. These warrants were not valued at December 31, 2006 as their exercise is conditioned on an event, the occurrence of which was undeterminable at December 31, 2006 and accordingly, had no reportable fair value at that date. In January 2007, the event occurred and the Company recorded a charge based on the warrants’ aggregate fair value determined at January 2007 of $433,750 (see Note 5).

1. The Company, Basis of Presentation and Summary of Significant Accounting Policies

The Company

On July 27, 2005, the stockholders approved an Agreement and Plan of Merger dated June 17, 2005 (the “Delaware reincorporation”) pursuant to which the Company merged with and into its newly created, wholly-owned subsidiary, Chelsea Therapeutics International, Ltd., a Delaware corporation (“Chelsea Delaware”), with Chelsea Delaware remaining as the surviving corporation.

The Delaware reincorporation also had the effect of the Company changing its corporate name to Chelsea Therapeutics International, Ltd. In addition, the Delaware reincorporation provided that each nine (9) shares of the no par value common stock of the Company outstanding at the date of the reincorporation was exchanged for one (1) share of the $0.0001 par value common stock of Chelsea Delaware (the “Share Exchange”). Fractional shares of Chelsea Delaware common stock were not issued in the Share Exchange and holders of the Company’s common stock who would have otherwise been entitled to receive a fractional share of Chelsea Delaware common stock received a cash payment equal to the fair market value of such fractional share as of the effective date of the Delaware reincorporation.

In accordance with the Share Exchange, Chelsea Delaware issued an aggregate of 12,368,514 shares of its common stock to the stockholders of the Company in exchange for the 111,317,378 shares of the Company’s common stock issued and outstanding as of the date of the Share Exchange. Accordingly, the Company has retroactively restated all share and per share data contained herein as if such exchange had occurred at the beginning of the earliest period presented.

The Chelsea Delaware Certificate of Incorporation authorizes the issuance of up to 45,000,000 shares of common stock, with $0.0001 par value per share and 5,000,000 shares of preferred stock with $0.0001 par value per share.

On February 11, 2005, pursuant to an Agreement and Plan of Merger dated as of January 17, 2005 (the “Merger Agreement”), Chelsea Therapeutics, Inc. (“Chelsea”) merged with and into Chelsea Acquisition Corp. (the “Merger”), a wholly-owned subsidiary of Ivory Capital Corporation (“Ivory”), which at that time was a reporting public corporation with no operations. In accordance with the Merger Agreement, each share of the outstanding preferred and common stock of Chelsea automatically converted into approximately 10.563 shares of the no par value common stock of Ivory. Accordingly, and after giving effect for the Delaware reincorporation and in connection with the Merger, Ivory issued an aggregate of 11,911,357 shares of its common stock to the former stockholders of Chelsea. At the date of the Merger, there were 457,168 shares of Ivory’s capital stock issued and outstanding. After giving effect to the issuance of shares in the Merger and the Delaware reincorporation, Ivory had outstanding 12,368,514 shares of common stock. In addition, immediately prior to the Merger, there were outstanding options and warrants to purchase 1,592,876 shares of the common stock of the Company. In conjunction with and immediately prior to the Merger, Chelsea issued additional warrants for the purchase of 105,516 shares of its common stock as consideration for events that facilitated the Merger.

Immediately after the date of the Merger, the parties who immediately prior thereto held common stock of Ivory continued to own an aggregate of 457,168 shares of the $0.0001 par value common stock of Ivory, equaling 3.25% of the outstanding common stock of Ivory on a fully diluted basis assuming exercise of all stock options, warrants and any other instruments that are convertible into equity.

Immediately after the Merger, Chelsea purchased all of the revolving notes outstanding with a face value of $33,292 under the a credit agreement between Ivory and its principal stockholders, together with all related rights

F-7

CHELSEA THERAPEUTICS INTERNATIONAL, LTD. AND SUBSIDIARY

(A Development Stage Company)

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

(including the option to convert the amounts due under the revolving notes into up to 444,444 shares of Ivory’s common stock), for $400,000 in cash. In connection with such purchase, the holders of such revolving notes released any and all claims against Ivory and Chelsea, including conversion rights as outlined in the note agreements.

The terms of the Merger provided that the sole officer and director of Ivory would be replaced by the officers and directors of Chelsea and having had no significant business activity for a number of years, upon the effective time of the Merger, Ivory adopted the business plan of Chelsea. The transaction was therefore accounted for as a reverse acquisition with Chelsea as the acquiring party and Ivory as the acquired party, in substance, a reorganization of Chelsea. Accordingly, the results of operations for the periods prior to the Merger are those of Chelsea.

Chelsea was incorporated in the State of Delaware on April 3, 2002 as Aspen Therapeutics, Inc. On July 8, 2004, Aspen amended its Certificate of Incorporation with the State of Delaware to change its name to Chelsea Therapeutics, Inc. Chelsea Therapeutics International, Ltd. was incorporated in the State of Delaware on June 17, 2005. Chelsea is a specialty pharmaceutical company focused on the acquisition, development and commercialization of innovative pharmaceutical products. The Company’s currently licensed compounds target a variety of prevalent medical conditions; particularly rheumatoid arthritis, psoriasis, cancer, other immunological disorders and neurogenic orthostatic hypotension.

As a result of the Merger of Ivory and Chelsea in February 2005, and the reincorporation in Delaware in July 2005, Chelsea Therapeutics International, Ltd. is the reporting company and is the 100% owner of Chelsea Therapeutics, Inc. The separate existence of Ivory Capital Corporate ceased in connection with the Delaware reincorporation in July 2005. Except where the context provides otherwise, references to “the Company”, “we”, “us”, “our” and similar terms mean Ivory, Chelsea Delaware and Chelsea.

Basis of Presentation

Since inception we have focused primarily on organizing and staffing our company, negotiating in-licensing agreements with our partners, acquiring, developing and securing our proprietary technology, participating in regulatory discussions with the FDA, the EMEA and other regulatory agencies and undertaking pre-clinical trials and clinical trials of our product candidates. We are a development stage company and have generated no revenue since inception.

The Company has sustained operating losses since its inception and expects such losses to continue over the next several years. Management plans to continue financing the operations with a combination of equity issuances and debt arrangements. If adequate funds are not available, the Company may be required to delay, reduce the scope of, or eliminate one or more of its research or development programs, or cease operations. Based on our resources at December 31, 2006 and our projection of spending needs during 2007, we will want to secure additional financing during 2007 to support our planned operational activities. If we are not able to obtain financing when needed, we might be unable to carry out our business plan. As a result, we might have to significantly delay certain activities or limit our operations and our business, financial condition and results of operations would be materially harmed.

For presentation purposes, the Company has restated all information contained in this report related to shares authorized, issued and outstanding and related disclosures of weighted average shares and loss per share to reflect the results of the Delaware reincorporation in July 2005 as if the Delaware reincorporation had occurred at the beginning of each of the periods presented.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

Basis of Consolidation

All significant intercompany transactions and balances have been eliminated in consolidation.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent liabilities at the date of the financial statements as well as the reported revenues and expenses during the reporting periods. On an ongoing basis, management evaluates its estimates and judgments. Management bases estimates on its historical experience and on various other factors that it believes are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

Cash and Cash Equivalents

Cash and cash equivalents consist of cash and other highly-liquid investments with maturities of three months or less from the date of purchase.

Concentration of Credit Risk

Financial instruments that potentially subject the Company to a significant concentration of credit risk consist primarily of cash and cash equivalents. The Company maintains deposits in federally insured financial institutions in excess of federally insured limits and holds investments in commercial paper with maturities no greater than ninety (90) days. However, management believes the Company is not exposed to significant credit risk due to the financial position of the depository institutions in which those deposits are held and the high credit ratings of the organizations issuing the various commercial paper investments.

Fair Value of Financial Instruments

The carrying value of the Company’s financial instruments, including cash and cash equivalents and accounts payable approximates fair value given their short-term nature.

Property and Equipment

Property, which consists of furniture and fixtures and equipment, is stated at cost and depreciated using the straight-line method over the estimated useful lives of the related assets. The useful life for all classes of assets is three (3) years.

Impairment of Long-Lived Assets

The Company reviews long-lived assets, including property and equipment, for impairment whenever events or changes in business circumstances indicate that the carrying amount of the assets may not be fully recoverable. An impairment loss would be recognized when estimated undiscounted future cash flows expected to result from the use of the asset and its eventual disposition are less than its carrying amount. The impairment loss, if recognized, would be based on the excess of the carrying value of the impaired asset over its respective fair value. Impairment, if any, is assessed using undiscounted cash flows. Through December 31, 2006, there has been no such impairment.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

Research and Development

Research and development expenditures are expensed as incurred. We often contract with third parties to facilitate, coordinate and perform agreed upon research and development activities. To ensure that research and development costs are expensed as incurred, we measure expense based on work performed for the underlying contract, typically utilizing a percentage-of-completion approach, and record prepaid assets or accrue expenses on a monthly basis for such activities based on the measurement of liability from expense recognition and the receipt of invoices.

These contracts typically call for the payment of fees for services at the initiation of the contract and/or upon the achievement of certain milestones. In the event that we prepay fees for future milestones, we record the prepayment as a prepaid asset and amortize the asset into research and development expense over the period of time the contracted research and development services are performed. Most fees are incurred throughout the contract period and are expensed based on their percentage of completion at a particular date.

These contracts generally include pass through fees. Pass through fees include, but are not limited to, regulatory expenses, investigator fees, travel costs, and other miscellaneous costs including shipping and printing fees. Because these fees are incurred at various times during the contract term and they are used throughout the contract term, we record a monthly expense allocation to recognize the fees during the contract period. Fees incurred to set up the clinical trial are expensed during the setup period.

Costs related to the acquisition of technology rights and patents for which development work is still in process are expensed as incurred and considered a component of research and development costs.

Loss per Share

Basic net loss per common share is calculated by dividing net loss by the weighted-average number of common shares outstanding for the period, without consideration for potentially dilutive securities. For the periods presented, basic and diluted net loss per common share are identical as potentially dilutive securities from stock options and stock warrants would have an antidilutive effect since the Company incurred a net loss. The number of shares of common stock potentially issuable at December 31, 2006, 2005 and 2004 upon exercise or conversion that were not included in the computation of net loss per share totaled 5,307,980, 1,641,157 and 847,536, respectively.

Income Taxes

In accordance with Statement of Financial Accounting Standards No. 109, Accounting for Income Taxes, a deferred tax asset or liability is determined based on the difference between the financial statement and the tax bases of assets and liabilities as measured by the enacted tax rates, which will be in effect when these differences reverse. The Company provides a valuation allowance against net deferred tax assets unless, based upon the available evidence, it is more likely than not that the deferred tax assets will be realized.

Stock-Based Compensation

On February 11, 2005, the date of the Merger, the Company adopted Statement of Financial Accounting Standards No. 123(R) (“SFAS 123R”), Share-based Payment to account for its stock options. SFAS 123R requires the measurement and recognition of compensation expense for all share-based payment awards made to employees and non-employee directors based on estimated fair values determined using an option-pricing model. The value of the portion of the award that is ultimately expected to vest is recognized as expense over the

F-10

CHELSEA THERAPEUTICS INTERNATIONAL, LTD. AND SUBSIDIARY

(A Development Stage Company)

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

requisite service periods in the Company’s Statements of Operations. Prior to the adoption of SFAS 123R, the Company accounted for stock options issued to employees and non-employee directors under Statement of Financial Accounting Standards No. 123 (“SFAS 123”), Accounting for Stock-based Compensation.

The Company adopted SFAS 123R using the modified prospective application to all grants made after February 11, 2005. The adoption of SFAS 123R had no effect on the financial results of the Company from the application of the original provisions of SFAS 123.

The fair value of each option award made to employees and directors during the years ended December 31, 2006, 2005 and 2004 was estimated on the date of grant using the Black-Scholes closed-form option valuation model utilizing the assumptions noted in the following table. To determine the risk-free interest rate, the Company utilized the U.S. Treasury yield curve in effect at the time of grant with a term consistent with the expected term of the Company’s awards. The Company estimated the expected life of the options granted based on anticipated exercises in future periods assuming the success of its business model as currently forecasted. The expected dividends reflect the Company’s current and expected future policy for dividends on its common stock. To determine the expected stock price volatility for the Company’s stock options, the Company examined historical volatilities for industry peers as the Company did not have sufficient trading history for its common stock. The Company will continue to analyze the expected stock price volatility and expected term assumption as more historical data for the Company’s common stock becomes available. Given the limited service period for its current employees and the senior nature of the roles for those employees, the Company currently estimates that it will experience no forfeitures for those options currently outstanding. Prior to February 11, 2005, under the provisions of SFAS 123, the Company utilized the minimum value model and assumed no volatility in determining the fair value of options granted. Due to the limited amount of historical data available to us, particularly with respect to stock-price volatility, employee exercise patterns and forfeitures, actual results could differ from our assumptions.

	For the years ended December 31,
	2006	2005	2004
Risk-free interest rate	4.31% to 5.12%	3.72% to 3.89%	3.58%
Expected life of options	5 years	5 years	5 years
Expected dividend yield	0%	0%	0%
Expected volatility	37.66%	0% to 41.31%	n/a
Forfeitures	0%	0%	n/a

The Company recorded compensation expense of $283,983, $99,319 and $1,529 for the years ended December 31, 2006, 2005 and 2004, respectively, in conjunction with option grants made to employees and non-employee directors. As of December 31, 2006, the Company had total unrecognized compensation expense related to options granted to employees and non-employee directors of $958,916, which will be recognized over a remaining average period of 2.9 years. The expected future amortization expense for unrecognized compensation expense for stock option grants to employees and non-employee directors at December 31, 2006 is as follows:

Year ending December 31, 2007	$	330,732
Year ending December 31, 2008		330,732
Year ending December 31, 2009		247,735

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

Options granted to consultants, advisors or other independent contractors that provide services to the Company are accounted for under the provisions of SFAS 123R and Emerging Issues Task Force Issue No. 96-18 (“EITF 96-18”), Accounting for Equity Instruments that are Issued to Other than Employees for Acquiring, or in Conjunction with Selling, Goods or Services. To date, option awards to consultants, advisors or other independent contractors have been granted with an exercise price equal to the market price of the Company’s stock at the date of the grant; have 10-year contractual terms; and vest dependent upon the completion of performance commitments. As such, the value of stock options is measured at the then-current market value as of financial reporting dates and compensation cost is recognized for the net change in the fair value of the options for the reporting period, until such performance commitments are met. Once each commitment is met, the options that vest in association with that commitment are adjusted, for the last-time, to the then-current fair value and compensation cost is recognized accordingly (See Note 6).

In determining the fair value of options granted to consultants, advisors and other independent contractors, the Company uses the Black-Scholes closed-form option valuation model in a manner consistent with its use in determining the fair value of options granted to employees and directors. However, the expected life of the options is based on the contractual lives as defined in agreements with the third parties and ranged from one to three years for grants made during 2005. No grants were made during 2006.

New Accounting Pronouncements

In July 2006, the FASB issued Interpretation No. 48 (“FIN No. 48”), Accounting for Uncertainty in Income Taxes. FIN No. 48 prescribes detailed guidance for the financial statement recognition, measurement and disclosure of uncertain tax positions recognized in an enterprise’s financial statements in accordance with FASB Statement No. 109 (“FAS No. 109”), Accounting for Income Taxes. Tax positions must meet a more-likely-than-not recognition threshold at the effective date to be recognized upon the adoption of FIN No. 48 and in subsequent periods. FIN No. 48 will be effective for fiscal years beginning after December 15, 2006 and the provisions of FIN No. 48 will be applied to all tax positions accounted for under FAS No. 109 upon initial adoption. The cumulative effect of applying the provisions of FIN No. 48 will be reported as an adjustment to the opening balance of retained earnings for that fiscal year. The Company currently believes that the adoption of FIN 48 will have no material impact on its consolidated financial position or results of operations.

In December 2006, the FASB issued FASB Staff Position EITF 00-19-2 (“FSP 00-19-2”), Accounting for Registration Payment Arrangements. FSP 00-19-2 addresses an issuer’s accounting for registration payment arrangements by specifying that the contingent obligation to make future payments or otherwise transfer consideration under a registration payment arrangement, whether issued as a separate agreement or included as a provision of a financial instrument or other agreement, should be separately recognized and measured in accordance with FASB Statement No. 5, Accounting for Contingencies. FSP 00-19-2 will be effective for fiscal years beginning after December 15, 2006, and interim periods within those fiscal years. The Company currently believes that the adoption of FSP 00-19-2 will have no material impact on its consolidated financial position or results of operations.

3. Private Placement of Common Stock

On February 13, 2006, the Company raised gross proceeds of approximately $21.5 million through the sale of 7,166,666 shares of its $0.0001 par value common stock plus warrants for the purchase of 2,149,999 shares of its $0.0001 par value common stock (the “2006 Placement”). The aggregate fair value of these warrants was approximately $1,488,000. The warrants permit the holders to purchase the underlying common shares, for cash only, at $4.20 each and are exercisable in whole at any time, or in part from time to time, for five years from the date of issuance. The warrants are redeemable at par value at the Company’s option in the event that the Company’s volume weighted-average closing bid price of its common stock is greater than $9.00 per share for any twenty (20) consecutive trading days provided that the Company gives thirty (30) business days’ written notice to the holders and simultaneously calls all warrants on the same terms. Under the terms of the 2006 Placement, the Company agreed to and filed a registration statement with the SEC within 30 days of the closing for the shares of common stock sold and the shares of common stock underlying the warrants and such registration became effective on March 29, 2006.

In December 2004, Chelsea Therapeutics, Inc. raised gross proceeds of approximately $14.5 million through the sale of 5,532,994 shares of its $0.0001 par value common stock. The amount raised includes the conversion of a $1.7 million stockholder loan along with accrued interest, for which a total of 677,919 shares of common stock were issued. In connection with this offering, Chelsea Therapeutics, Inc. engaged Paramount BioCapital, Inc. as placement agent and paid commissions and other offering-related expenses of approximately $1.0 million in cash and warrants to purchase 483,701 shares of its common stock with a fair value of approximately $0.03 per share.

4. Related Party Transactions

Finder’s Agreement

In May 2006, the Company entered into an agreement with Dainippon Sumitomo Pharma Co., Ltd. (“DSP”) for a worldwide, exclusive, sub-licensable license and rights to certain intellectual property and proprietary information (the “DSP Agreement”) relating to L-threo-3,4-dihydroxyphenylserine (“L-DOPS” or “droxidopa”). In conjunction with and as consideration for activities related to the execution of the DSP Agreement, the

F-13

CHELSEA THERAPEUTICS INTERNATIONAL, LTD. AND SUBSIDIARY

(A Development Stage Company)

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

Company entered into a Finder’s Agreement with Paramount BioCapital, Inc. (“Paramount”), a related party. Under the terms of the Finder’s Agreement, the Company paid Paramount an initial payment of $35,000 and issued warrants to Paramount or its affiliates for the purchase of 250,000 shares of its $0.0001 par value common stock at an exercise price of $4.31 per share. These warrants were not valued at December 31, 2006 as their exercise is conditioned on an event, the occurrence of which was undeterminable at December 31, 2006 and accordingly, had no reportable fair value at that date. In January 2007, the event occurred and the Company recorded a charge based on the warrants’ then determined aggregate fair value of $433,750. As additional consideration, the Company agreed to (1) make future milestone payments, upon achievement of milestones as defined in the Finder’s Agreement, to Paramount that totaled $185,000 as of December 31, 2006; (2) pay royalties on sales should any licensed compound become available for commercial sale; and (3) compensate a stated third-party consultant for services rendered in the evaluation of the transaction with DSP. Subsequent to December 31, 2006, the company made a milestone payment to under the Finder’s Agreement of $35,000 upon the granting of Orphan Drug designation for droxidopa for the treatment of symptomatic nuerogenic orthostatic hypotension by the United States Food & Drug Administration.

Financing Costs

The Company also engaged Paramount to act as placement agent (the “Agent”) for the 2006 placement (See Note 3). In connection with the 2006 Placement, Chelsea Therapeutics, Inc. paid the Agent commissions and other offering-related expenses of approximately $1.6 million in cash and issued warrants to designated employees of the Agent to purchase 716,666 shares of its $0.0001 par value common stock with an exercise price of 110% of the purchase price per share based on shares sold in the 2006 Placement, or $3.30 per share and an aggregate fair value of approximately $705,000. Under the terms of the financing we filed a registration statement with the SEC within 30 days of the closing for the shares of common stock underlying these warrants and such registration became effective on March 29, 2006. The Company has also agreed to indemnify the Agent against certain liabilities, including liabilities under the Securities Act of 1933.

The Company also engaged the Agent to act as placement agent for the December 2004 sale of shares of its $0.0001 par value common stock (the “2004 Placement”). In return for services provided, the Agent was paid approximately $888,000 in cash from the proceeds of the 2004 Placement and the Company issued warrants to the Agent for the purchase of 483,701 shares of its $0.0001 par value common stock with an exercise price of 110% of the purchase price per share based on shares sold in the 2004 Placement, or approximately $2.88 per share, with an aggregate fair value of approximately $14,400. At closing, the Company placed in escrow for the benefit of the Agent an accountable expense allowance equal to $50,000 to reimburse the Agent for out-of-pocket expenses related to the 2004 Placement. In January 2005, the unutilized portion of the expense allowance of approximately $12,900 was returned to the Company. Lastly, the Company agreed to indemnify the Agent against certain liabilities, including liabilities under the Securities Act of 1933.

Lindsay A. Rosenwald, M.D. is Chairman and Chief Executive Officer of the Agent and its affiliates. Certain trusts for the benefit of Dr. Rosenwald are substantial stockholders of the Company and participated in the Placement. As a result, Dr. Rosenwald might be deemed to be an affiliate of the Company.

Loans

At various times during 2004, Paramount BioCapital Investments, LLC, an affiliate of the Agent, loaned to the Company an aggregate principal amount of $1,745,000. The loans were evidence by promissory notes bearing interest at 5% per annum. At the date of the closing of the 2004 Placement, the loan had been assigned by

F-14

(A Development Stage Company)

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

Paramount BioCapital Investments, LLC to the Lindsay A. Rosenwald 2000 Irrevocable Trust (the “Trust”). In conjunction with the 2004 Placement, the Company issued 677,919 shares of its $0.0001 par value common stock to the Trust at a conversion rate of approximately $2.62 per share as repayment of the original $1,745,000 principal amount of the loan and $34,020 of interest thereon.

Other Relationships

Dr. Michael Weiser and Dr. Jason Stein, who are both members of the Board of Directors of the Company, were full-time employees of either the Agent or its affiliates until November 2006. In addition, Mr. David M. Tanen, who was a member of the Board of Directors of the Company until June 2006, was a full-time employee of the Agent until August 2004.

5. Commitments

Facility Lease

In 2004, the Company leased its corporate headquarters under an operating lease, as amended, that expires in June 2008. The lease contains no provisions for renewal periods of any fixed lengths. Should the Company decide to extend the lease beyond the current lease expiration date without successfully negotiating a new lease, such payment would be made on a month-to-month basis and, accordingly, are not included in the future minimum payment amount below. Rent expense for the years ended December 31, 2006, 2005 and 2004 was $56,278, $54,653 and $26,922, respectively.

Future minimum payments are $57,948 and $29,406 for the years ending December 31, 2007 and 2008, respectively.

License Agreements

In March 2004, the Company entered into a License Agreement with Dr. M. Gopal Nair, Ph.D., of the University of South Alabama College of Medicine, for rights to use, produce, distribute and market products derived from an invention by Dr. Nair, claimed in US Patent # 5,912,251, entitled “metabolically inert anti-inflammatory and antitumor antifolates”, designated by Chelsea as CH-1504 and related compounds. The license provides us exclusive, worldwide (excluding India) rights for CH-1504. The Company made an upfront payment in May 2004 of $150,000, a milestones payment as required by the agreement of $100,000 each in March 2006 and 2005 and is required to make additional payments upon the achievement of specific development and regulatory approval milestones. The Company is also obligated to pay royalties under the agreement until the later of the expiration of the applicable patent or the applicable last date of market exclusivity after the first commercial sale, on a country-by-country basis. Future potential milestone and anniversary payments total approximately $2,050,000 and there are no minimum royalties required under the agreement.

In May 2006, the Company entered into an agreement with Dainippon Sumitomo Pharma Co., Ltd. (“DSP”) for a worldwide, exclusive, sub-licensable license and rights to certain intellectual property and proprietary information (the “DSP Agreement”) relating to L-threo-3,4-dihydroxyphenylserine (“L-DOPS” or “droxidopa”) including, but not limited to all information, formulations, materials, data, drawings, sketches, designs, testing and test results, records and Regulatory Documentation. As consideration for these rights, the Company paid DSP $100,000 and issued 63,131 shares of its $0.0001 par value common stock, with a value of approximately $4.35 per share, or $274,621. As additional consideration, the Company agreed to pay DSP and or its designees (1) royalties on the sales should any compound be approved for commercial sale; and (2) milestone payments, payable upon achievement of milestones as defined in the DSP Agreement. At December 31, 2006, remaining

future milestone payments, subject to the Company’s right to terminate the license agreement, totaled $4.0 million. Subsequent to execution of the DSP Agreement, the Company and DSP have agreed to initiate, and the Company has agreed to fund, activities focused on modifying the manufacturing capabilities of DSP in order to expand capacity and comply with cGMP regulations and all existing manufacturing requirements of the United States Food and Drug Administration. Such activities are currently ongoing and shall continue over a two-year period. Based on work performed by DSP as of December 31, 2006, the Company had accrued approximately $0.9 million.

In January 2007, the Company received notification that the United States Food & Drug Administration had granted Orphan Drug designation for droxidopa for the treatment of symptomatic neurogenic orthostatic hypotension. Based on the terms of the DSP agreement, the granting of Orphan Drug designation for droxidopa generated a liability to DSP of $250,000. We paid such liability in February 2007. As of the date of that payment, remaining future milestone payments totaled $3.75 million.

The amount expended under these agreements and charged to research and development expense was $474,621, including the value of common stock issued, during the year ended December 31, 2006, $100,000 during the year ended December 31, 2005 and approximately $150,000 along with the issuance of 471,816 shares of the $0.0001 par value common stock of the Company with a nominal value during the year ended December 31, 2004.

Development and Commercialization Agreement

Effective May 2006, the Company entered into a development and commercialization agreement (the “Development Agreement”) with Active Biotech AB (“AB”) to co-develop and commercialize the I-3D portfolio of orally active, Dihydroorotate dehydrogenase (“DHODH”) inhibiting compounds for the treatment of autoimmune diseases and transplant rejection. Under the terms of the license and co-development agreement, an initial payment of $1.0 million was made to AB during the quarter ended June 30, 2006 with such funds to be utilized to cover the initial costs of research and development efforts jointly approved by both parties. At December 31, 2006 we had expensed the entire $1.0 million payment and had expensed additional costs of $0.3 million under the program related to costs of research and development. We also had recorded a net prepaid expense of approximately $0.1 million at December 31, 2006. Subsequent clinical development efforts shall be jointly conducted and funded by the Company and AB via a Joint Development Committee with equal representation from both parties. The partnership also establishes a licensing agreement providing Chelsea with the exclusive North and South American commercial rights to all drugs within this portfolio, while Active Biotech will retain rights for the remaining global markets. In addition to sharing development costs, both Chelsea and Active Biotech will pay the other partner royalty payments on sales in their respective markets. Active Biotech will also receive certain defined milestone payments related to clinical development and receipt of revenue from commercialization of the compounds. Unless terminated by either party with six months written notice, the Development Agreement shall remain in effect until the earlier of (1) the expiration of the last to expire patent rights indicated under the Development Agreement or (2) fifteen (15) years from the date of the first commercial sale of the product. As of December 31, 2006, remaining future milestone payments, subject to the Company’s right to terminate the Development Agreement, totaled $15.5 million.

Contract Research and Manufacturing Purchase Obligations

The Company often contracts with third parties to facilitate, coordinate and perform agreed upon research and development activities. These contracts typically call for the payment of fees for services at the initiation of the contract and/or upon the achievement of certain milestones. The Company currently intends to continue its research and manufacturing activities as contracted at December 31, 2006. However, there can be cancellation

Effective tax rate	0.00	%	0.00	%	0.00	%

Given the Company’s history of incurring operating losses, the Company’s ability to realize its deferred tax assets is not considered more likely than not. As a result, a valuation allowance equal to the total deferred tax assets has been established. The valuation allowance as of December 31, 2006, 2005 and 2004 was approximately $7.5 million, $4.2 million and $1.2 million, respectively.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

At December 31, 2006, the Company had potentially utilizable federal and state net operating loss carryforwards of approximately $18.4 million. The net operating loss carryforwards expire in various amounts for federal and state tax purposes through 2026 and 2021, respectively.

The utilization of the Company’s net operating losses may be subject to a substantial limitation should a change of ownership occur or have occurred, as defined under Section 382 of the Internal Revenue Code and similar state provisions. Such limitation could result in the expiration of the net operating loss carryforwards before their utilization.

8. Savings and Retirement Plan

During 2005, the Company established a savings and retirement plan under Section 401(k) of the Internal Revenue Code that allows eligible employees to annually contribute a portion of their annual salary to the plan. The Company matches such contributions up to a maximum of 4% of the employee’s salary, as defined. For the years ended December 31, 2006 and 2005, the Company made contributions of $47,695 and $38,894, respectively.

9. Subsequent Events

Orphan Drug Status and Milestone Payments

In January 2007, the Company received notification that the United States Food & Drug Administration had granted Orphan Drug designation for droxidopa for the treatment of symptomatic nuerogenic orthostatic hypotension. Based on the terms of the DSP agreement (see Note 5), the granting of Orphan Drug designation for droxidopa generated a liability of $250,000. We paid such liability in February 2007.

In addition, under terms of the Finder’s Agreement with Paramount BioCapital (see Note 4), the Company made a milestone payment of $35,000. The Company had also issued warrants under the Finder’s agreement to purchase 250,000 shares of its $0.0001 par value common stock, with an exercise price of $4.31 per share. These warrants were not valued at December 31, 2006 as their exercise is conditioned on the granting of orphan drug status by the FDA, the occurrence of which was undeterminable at December 31, 2006. Accordingly, the warrants had no reportable fair value at that date. In January 2007 the Company recorded a charge based on the warrants’ aggregate fair value of $433,750, determined as of the date Orphan Drug Status was granted.

Grant of Stock Options

Subsequent to December 31, 2006, the Company granted options for the purchase of 630,500 shares of its $0.0001 par value common stock to employees and non-employee directors. These grants, made during the first quarter of 2007, have a weighted average exercise price of $5.65 per share, a weighted average fair value of $3.35 per share and were granted at an exercise price equal to the closing market value of the Company’s stock on the dates of grant.

Exhibit 10.4

CHELSEA THERAPEUTICS INTERNATIONAL, LTD.

2004 STOCK PLAN

(As amended June 19, 2006)

1. Purpose. The purpose of the Amended and Restated 2004 Stock Plan (the “Plan”) of Chelsea Therapeutics International, Ltd. (the “Company”) is to increase shareholder value and to advance the interests of the Company by furnishing a variety of economic incentives (“Incentives”) designed to attract, retain and motivate employees, directors and consultants. Incentives may consist of opportunities to purchase or receive shares of Common Stock, $0.0001 par value, of the Company (“Common Stock”) on terms determined under this Plan.

2. Administration. The Plan shall be administered by a committee of the Board of Directors of the Company (the “Committee”). The Committee shall consist of not less than two directors of the Company who shall be appointed from time to time by the board of directors of the Company. Each member of the Committee shall be a “non-employee director” within the meaning of Rule 16b-3 of the Exchange Act of 1934, as amended (together with the rules and regulations promulgated thereunder, the “Exchange Act”), and an “outside director” as defined in Section 162(m) of the Internal Revenue Code of 1986, as amended (the “Code”). The Committee shall have complete authority to determine all provisions of all Incentives awarded under the Plan (as consistent with the terms of the Plan), to interpret the Plan, and to make any other determination which it believes necessary and advisable for the proper administration of the Plan. The Committee’s decisions and matters relating to the Plan shall be final and conclusive on the Company and its participants. No member of the Committee will be liable for any action or determination made in good faith with respect to the Plan or any Incentives granted under the Plan. The Committee will also have the authority under the Plan to amend or modify the terms of any outstanding Incentives in any manner; provided, however, that the amended or modified terms are permitted by the Plan as then in effect and that any recipient of an Incentive adversely affected by such amended or modified terms has consented to such amendment or modification. No amendment or modification to an Incentive, however, whether pursuant to this Section 2 or any other provision of the Plan, will be deemed to be a re-grant of such Incentive for purposes of this Plan (notwithstanding that such amendment or modification may be deemed to be a new grant of an incentive stock option, as such term is defined in Section 422 of the Code, under the Code). If at any time there is no Committee, then for purposes of the Plan the term “Committee” shall mean the Company’s Board of Directors.

3. Eligible Participants. Employees of the Company or its subsidiaries (including officers and employees of the Company or its subsidiaries), directors and consultants, advisors or other independent contractors who provide services to the Company or its subsidiaries (including members of the Company’s scientific advisory board) shall become eligible to receive Incentives under the Plan when designated by the Committee. Participants may be designated individually or by groups or categories (for example, by pay grade) as the Committee deems appropriate. Participation by officers of the Company or its subsidiaries and any performance objectives relating to such officers must be approved by the Committee. Participation by others and any performance objectives relating to others may be approved by groups or categories (for example, by pay grade) and authority to designate participants who are not officers and to set or modify such targets may be delegated.

4. Types of Incentives. Incentives under the Plan may be granted in any one or a combination of the following forms: (a) incentive stock options and non-statutory stock options (Section 6); (b) stock appreciation rights (“SARs”) (Section 7); (c) stock awards (Section 8); (d) restricted stock (Section 8); and (e) performance shares (Section 9). Only employees of the Company shall be entitled to receive incentive stock options under Section 422 of the Code.

5. Shares Subject to the Plan.

5.1. Number of Shares. Subject to adjustment as provided in Section 11.6, the number of shares of Common Stock which may be issued under the Plan is 2,645,000 shares of Common Stock. Of such

aggregate number of shares of Common Stock that may be issued under the Plan, the maximum number of shares that may be issued as incentive stock options under Section 422 of the Code is 2,645,000. Any shares of Common Stock available for issuance as incentive stock options may be alternatively issued as other types of Incentives under the Plan. Shares of Common Stock that are issued under the Plan or that are subject to outstanding Incentives will be applied to reduce the maximum number of shares of Common Stock remaining available for issuance under the Plan.

5.2. Cancellation. To the extent that cash in lieu of shares of Common Stock is delivered upon the exercise of an SAR pursuant to Section 7.4, the Company shall be deemed, for purposes of applying the limitation on the number of shares, to have issued the greater of the number of shares of Common Stock which it was entitled to issue upon such exercise or on the exercise of any related option. In the event that a stock option or SAR granted hereunder expires or is terminated or canceled unexercised or unvested as to any shares of Common Stock, such shares may again be issued under the Plan either pursuant to stock options, SARs or otherwise. In the event that shares of Common Stock are issued as restricted stock or pursuant to a stock award and thereafter are forfeited or reacquired by the Company pursuant to rights reserved upon issuance thereof, such forfeited and reacquired shares may again be issued under the Plan, either as restricted stock, pursuant to stock awards or otherwise. Shares of Common Stock which are withheld to pay the exercise price of an option and/or any related withholding obligations shall again be available for issuance under the Plan. The Committee may also determine to cancel, and agree to the cancellation of, stock options in order to make a participant eligible for the grant of a stock option at a lower price than the option to be canceled.

6. Stock Options. A stock option is a right to purchase shares of Common Stock from the Company. The Committee may designate whether an option is to be considered an incentive stock option or a non-statutory stock option. To the extent that any incentive stock option granted under the Plan ceases for any reason to qualify as an “incentive stock option” for purposes of Section 422 of the Code, such incentive stock option will continue to be outstanding for purposes of the Plan but will thereafter be deemed to be a non-statutory stock option. Each stock option granted by the Committee under this Plan shall be subject to the following terms and conditions:

6.1. Price. The option price per share shall be determined by the Committee, subject to adjustment under Section 11.6.

6.2. Number. The number of shares of Common Stock subject to the option shall be determined by the Committee, subject to adjustment as provided in Section 11.6. The number of shares of Common Stock subject to a stock option shall be reduced in the same proportion that the holder thereof exercises a SAR if any SAR is granted in conjunction with or related to the stock option.

6.3. Duration and Time for Exercise. Subject to earlier termination as provided in Section 11.4 and except for incentive stock options which shall be subject to the provisions of Section 6.5, the term of each stock option shall be determined by the Committee but shall not exceed ten years from the date of grant. Each stock option shall become exercisable at such time or times during its term as shall be determined by the Committee at the time of grant. The Committee may accelerate the exercisability of any stock option.

6.4. Manner of Exercise. Subject to the conditions contained in this Plan and in the agreement with the recipient evidencing such option, a stock option may be exercised, in whole or in part, by giving written notice to the Company, specifying the number of shares of Common Stock to be purchased and accompanied by the full purchase price for such shares. The exercise price shall be payable (a) in United States dollars upon exercise of the option and may be paid by cash; uncertified or certified check; bank draft; (b) at the discretion of the Committee, by delivery of shares of Common Stock that are already owned by the participant in payment of all or any part of the exercise price, which shares shall be valued for this purpose at the Fair Market Value on the date such option is exercised; or (c) at the discretion of the Committee, by instructing the Company to withhold from the shares of Common Stock issuable upon exercise of the stock option shares of Common Stock in payment of all or any part of the exercise price and/or any related withholding tax obligations, which shares shall be valued for this purpose at the Fair Market

2

Value or in such other manner as may be authorized from time to time by the Committee. The shares of Common Stock delivered by the participant pursuant to Section 6.4(b) must have been held by the participant for a period of not less than six months prior to the exercise of the option, unless otherwise determined by the Committee. Prior to the issuance of shares of Common Stock upon the exercise of a stock option, a participant shall have no rights as a shareholder. Except as otherwise provided in the Plan, no adjustment will be made for dividends or distributions with respect to such stock options as to which there is a record date preceding the date the participant becomes the holder of record of such shares, except as the Committee may determine in its discretion.

6.5. Incentive Stock Options. Notwithstanding anything in the Plan to the contrary, the following additional provisions shall apply to the grant of stock options which are intended to qualify as incentive stock options (as such term is defined in Section 422 of the Code):

(a) To the extent that the aggregate Fair Market Value (determined as of the time the option is granted) of the shares of Common Stock with respect to which incentive stock options are exercisable for the first time by any participant during any calendar year (under the Plan and any other incentive stock option plans of the Company or any subsidiary or parent corporation of the Company) shall exceed $100,000, such excess portion of the incentive stock options will be treated as Non-Statutory Stock Options; provided that this provision shall have no force or effect to the extent that its inclusion in the Plan is not necessary for the Incentive to qualify as incentive stock options pursuant to Section 422 of the Code. The determination will be made by taking incentive stock options into account in the order in which they were granted.

(b) Any incentive stock option certificate authorized under the Plan shall contain such other provisions as the Committee shall deem advisable, but shall in all events be consistent with and contain all provisions required in order to qualify the options as incentive stock options.

(c) All incentive stock options must be granted within ten years from the earlier of the date on which this Plan was adopted by board of directors or the date this Plan was approved by the Company’s shareholders.

(d) Unless sooner exercised, all incentive stock options shall expire no later than 10 years after the date of grant. No incentive stock option may be exercisable after ten (10) years from its date of grant (or five (5) years from its date of grant if, at the time the incentive stock option is granted, the Participant owns, directly or indirectly, more than 10% of the total combined voting power of all classes of stock of the Company or any parent or subsidiary corporation of the Company).

(e) The exercise price for incentive stock options shall be not less than 100% of the Fair Market Value of the Common Stock subject thereto on the date of grant; provided that the exercise price shall be 110% of the Fair Market Value if, at the time the incentive stock option is granted, the participant owns, directly or indirectly, more than 10% of the total combined voting power of all classes of stock of the Company or any parent or subsidiary corporation of the Company.

7. Stock Appreciation Rights. An SAR is a right to receive, without payment to the Company, a number of shares of Common Stock, cash or any combination thereof, the amount of which is determined pursuant to the formula set forth in Section 7.4. An SAR may be granted (a) with respect to any stock option granted under this Plan, either concurrently with the grant of such stock option or at such later time as determined by the Committee (as to all or any portion of the shares of Common Stock subject to the stock option), or (b) alone, without reference to any related stock option. Each SAR granted by the Committee under this Plan shall be subject to the following terms and conditions:

7.1. Number; Exercise Price. Each SAR granted to any participant shall relate to such number of shares of Common Stock as shall be determined by the Committee, subject to adjustment as provided in Section 11.6. In the case of an SAR granted with respect to a stock option, the number of shares of Common Stock to which the SAR pertains shall be reduced in the same proportion that the holder of the option

3

exercises the related stock option. The exercise price of an SAR will be determined by the Committee, in its discretion, at the date of grant but may not be less than 100% of the Fair Market Value of the shares of Common Stock subject thereto on the date of grant.

7.2. Duration. Subject to earlier termination as provided in Section 11.4, the term of each SAR shall be determined by the Committee but shall not exceed ten years and one day from the date of grant. Unless otherwise provided by the Committee, each SAR shall become exercisable at such time or times, to such extent and upon such conditions as the stock option, if any, to which it relates is exercisable. The Committee may in its discretion accelerate the exercisability of any SAR.

7.3. Exercise. An SAR may be exercised, in whole or in part, by giving written notice to the Company, specifying the number of SARs which the holder wishes to exercise. Upon receipt of such written notice, the Company shall, within 90 days thereafter, deliver to the exercising holder certificates for the shares of Common Stock or cash or both, as determined by the Committee, to which the holder is entitled pursuant to Section 7.4.

7.4. Payment. Subject to the right of the Committee to deliver cash in lieu of shares of Common Stock (which, as it pertains to officers and directors of the Company, shall comply with all requirements of the Exchange Act), the number of shares of Common Stock which shall be issuable upon the exercise of an SAR shall be determined by dividing:

(a) the number of shares of Common Stock as to which the SAR is exercised multiplied by the amount of the appreciation in such shares (for this purpose, the “appreciation” shall be the amount by which the Fair Market Value of the shares of Common Stock subject to the SAR on the exercise date exceeds (1) in the case of an SAR related to a stock option, the exercise price of the shares of Common Stock under the stock option or (2) in the case of an SAR granted alone, without reference to a related stock option, an amount which shall be determined by the Committee at the time of grant, subject to adjustment under Section 11.6); by

(b) the Fair Market Value of a share of Common Stock on the exercise date.

In lieu of issuing shares of Common Stock upon the exercise of a SAR, the Committee may elect to pay the holder of the SAR cash equal to the Fair Market Value on the exercise date of any or all of the shares which would otherwise be issuable. No fractional shares of Common Stock shall be issued upon the exercise of an SAR; instead, the holder of the SAR shall be entitled to receive a cash adjustment equal to the same fraction of the Fair Market Value of a share of Common Stock on the exercise date or to purchase the portion necessary to make a whole share at its Fair Market Value on the date of exercise.

8. Stock Awards and Restricted Stock. A stock award consists of the transfer by the Company to a participant of shares of Common Stock, without other payment therefor, as additional compensation for services to the Company. The participant receiving a stock award will have all voting, dividend, liquidation and other rights with respect to the shares of Common Stock issued to a participant as a stock award under this Section 8 upon the participant becoming the holder of record of such shares. A share of restricted stock consists of shares of Common Stock which are sold or transferred by the Company to a participant at a price determined by the Committee (which price shall be at least equal to the minimum price required by applicable law for the issuance of a share of Common Stock) and subject to restrictions on their sale or other transfer by the participant, which restrictions and conditions may be determined by the Committee as long as such restrictions and conditions are not inconsistent with the terms of the Plan. The transfer of Common Stock pursuant to stock awards and the transfer and sale of restricted stock shall be subject to the following terms and conditions:

8.1. Number of Shares. The number of shares to be transferred or sold by the Company to a participant pursuant to a stock award or as restricted stock shall be determined by the Committee.

8.2. Sale Price. The Committee shall determine the price, if any, at which shares of restricted stock shall be sold or granted to a participant, which may vary from time to time and among participants and which may be below the Fair Market Value of such shares of Common Stock at the date of sale.

4

8.3. Restrictions. All shares of restricted stock transferred or sold hereunder shall be subject to such restrictions as the Committee may determine, including, without limitation any or all of the following:

(a) a prohibition against the sale, transfer, pledge or other encumbrance of the shares of restricted stock, such prohibition to lapse at such time or times as the Committee shall determine (whether in annual or more frequent installments, at the time of the death, disability or retirement of the holder of such shares, or otherwise);

(b) a requirement that the holder of shares of restricted stock forfeit, or (in the case of shares sold to a participant) resell back to the Company at his or her cost, all or a part of such shares in the event of termination of his or her employment or consulting engagement during any period in which such shares are subject to restrictions; or

(c) such other conditions or restrictions as the Committee may deem advisable.

8.4. Escrow. In order to enforce the restrictions imposed by the Committee pursuant to Section 8.3, the participant receiving restricted stock shall enter into an agreement with the Company setting forth the conditions of the grant. Shares of restricted stock shall be registered in the name of the participant and deposited, together with a stock power endorsed in blank, with the Company. Each such certificate shall bear a legend in substantially the following form:

The transferability of this certificate and the shares of Common Stock represented by it are subject to the terms and conditions (including conditions of forfeiture) contained in the 2004 Stock Plan of Chelsea Therapeutics International, Ltd., (the “Company”), as amended from time to time, and an agreement entered into between the registered owner and the Company. A copy of the 2004 Stock Plan, as amended from time to time, and the agreement is on file in the office of the secretary of the Company.

8.5. End of Restrictions. Subject to Section 11.5, at the end of any time period during which the shares of restricted stock are subject to forfeiture and restrictions on transfer, such shares will be delivered free of all restrictions to the participant or to the participant’s legal representative, beneficiary or heir.

8.6. Shareholder. Subject to the terms and conditions of the Plan, each participant receiving restricted stock shall have all the rights of a shareholder with respect to shares of stock during any period in which such shares are subject to forfeiture and restrictions on transfer, including without limitation, the right to vote such shares. Dividends paid in cash or property other than Common Stock with respect to shares of restricted stock shall be paid to the participant currently.

9. Performance Shares. A performance share consists of an award which shall be paid in shares of Common Stock, as described below. The grant of a performance share shall be subject to such terms and conditions as the Committee deems appropriate, including the following:

9.1. Performance Objectives. Each performance share will be subject to performance objectives for the Company or one of its operating units to be achieved by the participant before the end of a specified period. The number of performance shares granted shall be determined by the Committee and may be subject to such terms and conditions, as the Committee shall determine. If the performance objectives are achieved, each participant will be paid in shares of Common Stock or cash as determined by the Committee. If such objectives are not met, each grant of performance shares may provide for lesser payments in accordance with formulas established in the award.

9.2. Not Shareholder. The grant of performance shares to a participant shall not create any rights in such participant as a shareholder of the Company, until the payment of shares of Common Stock with respect to an award.

9.3. No Adjustments. No adjustment shall be made in performance shares granted on account of cash dividends which may be paid or other rights which may be issued to the holders of Common Stock prior to the end of any period for which performance objectives were established.

5

9.4. Expiration of Performance Share. If any participant’s employment or consulting engagement with the Company is terminated for any reason other than normal retirement, death or disability prior to the achievement of the participant’s stated performance objectives, all the participant’s rights on the performance shares shall expire and terminate unless otherwise determined by the Committee. In the event of termination of employment or consulting by reason of death, disability, or normal retirement, the Committee, in its own discretion may determine what portions, if any, of the performance shares should be paid to the participant.

10. Change of Control.

10.1 Change in Control. For purposes of this Section 10, a “Change in Control” of the Company will mean the following:

(a) the sale, lease, exchange or other transfer, directly or indirectly, of substantially all of the assets of the Company (in one transaction or in a series of related transactions) to a person or entity that is not controlled by the Company;

(b) the approval by the shareholders of the Company of any plan or proposal for the liquidation or dissolution of the Company;

(c) any person not a shareholder of the Company on the date of the Plan becomes after the effective date of the Plan the “beneficial owner” (as defined in Rule 13d-3 under the Exchange Act), directly or indirectly, of (i) 20% or more, but not 50% or more, of the combined voting power of the Company’s outstanding securities ordinarily having the right to vote at elections of directors, unless the transaction resulting in such ownership has been approved in advance by the Continuing Directors (as defined below), or (ii) 50% or more of the combined voting power of the Company’s outstanding securities ordinarily having the right to vote at elections of directors (regardless of any approval by the Continuing Directors); provided that a traditional institutional or venture capital financing transaction shall be excluded from this definition; or

(d) a merger or consolidation to which the Company is a party if the shareholders of the Company immediately prior to the effective date of such merger or consolidation have “beneficial ownership” (as defined in Rule 13d-3 under the Exchange Act), immediately following the effective date of such merger or consolidation, of securities of the surviving corporation representing (i) 50% or more, but less than 80%, of the combined voting power of the surviving corporation’s then outstanding securities ordinarily having the right to vote at elections of directors, unless such merger or consolidation has been approved in advance by the Continuing Directors, or (ii) less than 50% of the combined voting power of the surviving corporation’s then outstanding securities ordinarily having the right to vote at elections of directors (regardless of any approval by the Continuing Directors).

10.2 Continuing Directors. For purposes of this Section 10, “Continuing Directors” of the Company will mean any individuals who are members of the Board on the effective date of the Plan and any individual who subsequently becomes a member of the Board whose election, or nomination for election by the Company’s shareholders, was approved by a vote of at least a majority of the Continuing Directors (either by specific vote or by approval of the Company’s proxy statement in which such individual is named as a nominee for director without objection to such nomination).

10.3 Acceleration of Incentives. Unless otherwise resolved by the Committee in its sole discretion at such time, if a Change in Control of the Company occurs whereby the acquiring entity or successor to the Company does not agree to assume the Incentives or replace them with substantially equivalent incentive awards (as determined by the Committee in its reasonable discretion), then (a) all outstanding options and SARs will vest and will become immediately exercisable in full and, if not exercised on the date of the Change of Control, will terminate on such date regardless of whether the participant to whom such options or SARs have been granted remains in the employ or service of the Company or any subsidiary of the Company or any acquiring entity or successor to the Company; (b) the restrictions on all shares of restricted

6

stock awards shall lapse immediately; and (c) all performance shares criteria shall be deemed to be met and payment made immediately.

10.4 Cash Payment for Options. If a Change in Control of the Company occurs, then the Committee, if approved by the Committee in its sole discretion either in an agreement evidencing an option at the time of grant or at any time after the grant of an option, and without the consent of any participant affected thereby, may determine that:

(a) some or all participants holding outstanding options will receive, with respect to some or all of the shares of Common Stock subject to such options, as of the effective date of any such Change in Control of the Company, cash in an amount equal to the excess of the Fair Market Value of such shares immediately prior to the effective date of such Change in Control of the Company over the exercise price per share of such options; and

(b) any options as to which, as of the effective date of any such Change in Control, the Fair Market Value of the shares of Common Stock subject to such options is less than or equal to the exercise price per share of such options, shall terminate as of the effective date of any such Change in Control.

If the Committee makes a determination as set forth in subparagraph (a) of this Section 10.4, then as of the effective date of any such Change in Control of the Company such options will terminate as to such shares and the participants formerly holding such options will only have the right to receive such cash payment(s). If the Committee makes a determination as set forth in subparagraph (b) of this Section 10.4, then as of the effective date of any such Change in Control of the Company such options will terminate, become void and expire as to all unexercised shares of Common Stock subject to such options on such date, and the participants formerly holding such options will have no further rights with respect to such options.

11. General.

11.1. Effective Date. The Plan will become effective upon approval by the Company’s board of directors.

11.2. Duration. The Plan shall remain in effect until all Incentives granted under the Plan have either been satisfied by the issuance of shares of Common Stock or the payment of cash or been terminated under the terms of the Plan and all restrictions imposed on shares of Common Stock in connection with their issuance under the Plan have lapsed. No Incentives may be granted under the Plan after the earlier of the tenth anniversary of the date of the adoption of the Plan or the date the Plan is approved by the shareholders of the Company.

11.3. Non-transferability of Incentives. Except in the event of the holder’s death, by will or the laws of descent and distribution to the limited extent provided in the Plan or the Incentive, unless approved by the Committee, no stock option, SAR, restricted stock or performance award may be transferred, pledged or assigned by the holder thereof, either voluntarily or involuntarily, directly or indirectly, by operation of law or otherwise, and the Company shall not be required to recognize any attempted assignment of such rights by any participant. During a participant’s lifetime, an Incentive may be exercised only by him or her or by his or her guardian or legal representative.

11.4. Effect of Termination or Death. In the event that a participant ceases to be an employee of or consultant to the Company, or the participants’ other service with the Company is terminated, for any reason, including death, any Incentives may be exercised or shall expire at such times as may be determined by the Committee in its sole discretion in the agreement evidencing an Incentive. Notwithstanding the other provisions of this Section 11.4, upon a participant’s termination of employment or other service with the Company and all subsidiaries, the Committee may, in its sole discretion (which may be exercised at any time on or after the date of grant, including following such termination), cause options and SARs (or any part thereof) then held by such participant to become or continue to become exercisable and/or remain exercisable following such termination of employment or service and Restricted Stock Awards,

7

Performance Shares and Stock Awards then held by such participant to vest and/or continue to vest or become free of transfer restrictions, as the case may be, following such termination of employment or service, in each case in the manner determined by the Committee; provided, however, that no Incentive may remain exercisable or continue to vest beyond its expiration date. Any incentive stock option that remains unexercised more than one (1) year following termination of employment by reason of death or disability or more than three (3) months following termination for any reason other than death or disability will thereafter be deemed to be a Non-Statutory Stock Option.

11.5. Additional Conditions. Notwithstanding anything in this Plan to the contrary: (a) the Company may, if it shall determine it necessary or desirable for any reason, at the time of award of any Incentive or the issuance of any shares of Common Stock pursuant to any Incentive, require the recipient of the Incentive, as a condition to the receipt thereof or to the receipt of shares of Common Stock issued pursuant thereto, to deliver to the Company a written representation of present intention to acquire the Incentive or the shares of Common Stock issued pursuant thereto for his or her own account for investment and not for distribution; and (b) if at any time the Company further determines, in its sole discretion, that the listing, registration or qualification (or any updating of any such document) of any Incentive or the shares of Common Stock issuable pursuant thereto is necessary on any securities exchange or under any federal or state securities or blue sky law, or that the consent or approval of any governmental regulatory body is necessary or desirable as a condition of, or in connection with the award of any Incentive, the issuance of shares of Common Stock pursuant thereto, or the removal of any restrictions imposed on such shares, such Incentive shall not be awarded or such shares of Common Stock shall not be issued or such restrictions shall not be removed, as the case may be, in whole or in part, unless such listing, registration, qualification, consent or approval shall have been effected or obtained free of any conditions not acceptable to the Company. Notwithstanding any other provision of the Plan or any agreements entered into pursuant to the Plan, the Company will not be required to issue any shares of Common Stock under this Plan, and a participant may not sell, assign, transfer or otherwise dispose of shares of Common Stock issued pursuant to any Incentives granted under the Plan, unless (a) there is in effect with respect to such shares a registration statement under the Securities Act of 1933, as amended (the “Securities Act”), and any applicable state or foreign securities laws or an exemption from such registration under the Securities Act and applicable state or foreign securities laws, and (b) there has been obtained any other consent, approval or permit from any other regulatory body which the Committee, in its sole discretion, deems necessary or advisable. The Company may condition such issuance, sale or transfer upon the receipt of any representations or agreements from the parties involved, and the placement of any legends on certificates representing shares of Common Stock, as may be deemed necessary or advisable by the Company in order to comply with such securities laws or other restrictions. The Committee may restrict the rights of participants to the extent necessary to comply with Section 16(b) of the Exchange Act, the Internal Revenue Code or any other applicable law or regulation. The grant of an Incentive award pursuant to the Plan shall not limit in any way the right or power of the Company to make adjustments, reclassifications, reorganizations or changes of its capital or business structure or to merge, exchange or consolidate or to dissolve, liquidate, sell or transfer all or any part of its business or assets.

11.6. Adjustment. In the event of any recapitalization, stock dividend, stock split, combination of shares or other change in the Common Stock, the number of shares of Common Stock then subject to the Plan, including shares subject to restrictions, options or achievements of performance shares, shall be adjusted in proportion to the change in outstanding shares of Common Stock. In the event of any such adjustments, the purchase price of any option, the performance objectives of any Incentive, and the shares of Common Stock issuable pursuant to any Incentive shall be adjusted as and to the extent appropriate, in the discretion of the Committee, to provide participants with the same relative rights before and after such adjustment.

11.7. Incentive Plans and Agreements. Except in the case of stock awards, the terms of each Incentive shall be stated in a plan or agreement approved by the Committee. The Committee may also determine to enter into agreements with holders of options to reclassify or convert certain outstanding options, within the

8

terms of the Plan, as incentive stock options or as non-statutory stock options and in order to eliminate SARs with respect to all or part of such options and any other previously issued options.

11.8. Withholding.

(a) The Company shall have the right to (i) withhold and deduct from any payments made under the Plan or from future wages of the participant (or from other amounts that may be due and owing to the participant from the Company or a subsidiary of the Company), or make other arrangements for the collection of, all legally required amounts necessary to satisfy any and all foreign, federal, state and local withholding and employment-related tax requirements attributable to an Incentive, or (ii) require the participant promptly to remit the amount of such withholding to the Company before taking any action, including issuing any shares of Common Stock, with respect to an Incentive. At any time when a participant is required to pay to the Company an amount required to be withheld under applicable income tax laws in connection with a distribution of Common Stock or upon exercise of an option or SAR, the participant may satisfy this obligation in whole or in part by electing (the “Election”) to have the Company withhold from the distribution shares of Common Stock having a value up to the amount required to be withheld. The value of the shares to be withheld shall be based on the Fair Market Value of the Common Stock on the date that the amount of tax to be withheld shall be determined (“Tax Date”).

(b) Each Election must be made prior to the Tax Date. The Committee may disapprove of any Election, may suspend or terminate the right to make Elections, or may provide with respect to any Incentive that the right to make Elections shall not apply to such Incentive. An Election is irrevocable.

(c) If a participant is an officer or director of the Company within the meaning of Section 16 of the Exchange Act, then an Election is subject to the following additional restrictions:

(1) No Election shall be effective for a Tax Date which occurs within six months of the grant or exercise of the award, except that this limitation shall not apply in the event death or disability of the participant occurs prior to the expiration of the six-month period.

(2) The Election must be made either six months prior to the Tax Date or must be made during a period beginning on the third business day following the date of release for publication of the Company’s quarterly or annual summary statements of sales and earnings and ending on the twelfth business day following such date.

(d) If the option granted to a participant hereunder is an incentive stock option, and if the participant sells or otherwise disposes of any of the shares of Common Stock acquired pursuant to the incentive stock option on or before the later of (1) the date two years after the date of grant, or (2) the date one year after the date of exercise, the participant shall immediately notify the Company in writing of such disposition. The participant agrees that the participant may be subject to income tax withholding by the Company on the compensation income recognized by the participant from the early disposition by payment in cash or out of the current earnings paid to the participant.

11.9. No Continued Employment, Engagement or Right to Corporate Assets. No participant under the Plan shall have any right, because of his or her participation, to continue in the employ of the Company for any period of time or any right to continue his or her present or any other rate of compensation. Nothing contained in the Plan shall be construed as giving an employee, a consultant, such persons’ beneficiaries or any other person any interests of any kind in the assets of the Company or creating a trust of any kind or a fiduciary relationship of any kind between the Company and any such person.

11.10. Deferral Permitted. Payment of cash or distribution of any shares of Common Stock to which a participant is entitled under any Incentive shall be made as provided in the Incentive. Payment may be deferred at the option of the participant if provided in the Incentive.

11.11. Amendment of the Plan. The Board may amend, suspend or discontinue the Plan at any time; provided, however, that no amendments to the Plan will be effective without approval of the shareholders of

9

the Company if shareholder approval of the amendment is then required pursuant to Section 422 of the Code, the regulations promulgated thereunder or the rules of any stock exchange or Nasdaq or similar regulatory body. No termination, suspension or amendment of the Plan may adversely affect any outstanding Incentive without the consent of the affected participant; provided, however, that this sentence will not impair the right of the Committee to take whatever action it deems appropriate under Sections 2, 10 and 11 of the Plan.

11.12. Definition of Fair Market Value. For purposes of this Plan, the “Fair Market Value” of a share of Common Stock at a specified date shall, unless otherwise expressly provided in this Plan, be the amount which the Committee or the board of directors of the Company determines in good faith in the exercise of its reasonable discretion to be 100% of the fair market value of such a share as of the date in question; provided, however, that notwithstanding the foregoing, if such shares are listed on a U.S. securities exchange or are quoted on the Nasdaq National Market System or Nasdaq SmallCap Stock Market (“Nasdaq”), then Fair Market Value shall be determined by reference to the last sale price of a share of Common Stock on such U.S. securities exchange or Nasdaq on the applicable date. If such U.S. securities exchange or Nasdaq is closed for trading on such date, or if the Common Stock does not trade on such date, then the last sale price used shall be the one on the date the Common Stock last traded on such U.S. securities exchange or Nasdaq.

11.13 Breach of Confidentiality, Assignment of Inventions, or Non-Compete Agreements. Notwithstanding anything in the Plan to the contrary, in the event that a participant materially breaches the terms of any confidentiality, assignment of inventions, or non-compete agreement entered into with the Company or any subsidiary of the Company, whether such breach occurs before or after termination of such participant’s employment or other service with the Company or any subsidiary, the Committee in its sole discretion may immediately terminate all rights of the participant under the Plan and any agreements evidencing an Incentive then held by the participant without notice of any kind.

11.13 Governing Law. The validity, construction, interpretation, administration and effect of the Plan and any rules, regulations and actions relating to the Plan will be governed by and construed exclusively in accordance with the laws of the State of North Carolina, notwithstanding the conflicts of laws principles of any jurisdictions.

11.14 Successors and Assigns. The Plan will be binding upon and inure to the benefit of the successors and permitted assigns of the Company and the participants in the Plan.

STOCK OPTION AGREEMENT

1. Grant of Option. Chelsea Therapeutics International, Ltd. a Delaware corporation (the “Company”), hereby grants to the Optionee named in the Notice of Grant (the “Optionee”) an option (the “Option”) to purchase a total number of shares of Common Stock (the “Shares”) set forth in the Notice of Grant, at the exercise price per share set forth in the Notice of Grant (the “Exercise Price”) subject to the terms, definitions and provisions of the Chelsea Therapeutics International, Ltd. 2004 Stock Plan (as amended, the “Plan”) adopted by the Company, which is incorporated herein by reference. Unless otherwise defined herein, the terms defined in the Plan shall have the same defined meanings in this Option. To the extent of any conflict between the terms of this Stock Option Agreement and the Plan, the terms of the Plan shall control.

If designated an Incentive Stock Option, this Option is intended to qualify as an Incentive Stock Option as defined in Section 422 of the Code, or any successor provision.

2. Exercise of Option. This Option shall be exercisable during its term in accordance with the Vesting Schedule set out in the Notice of Grant, the terms of the Plan and as follows:

(a) Right to Exercise.

(i) This Option may not be exercised for a fraction of a share.

(ii) In the event of Optionee’s death, disability or other termination of employment, the exercisability of the Option is governed by Sections 6, 7 and 8 below, subject to the limitation contained in subsection 2(a)(iii).

(iii) In no event may this Option be exercised after the date of expiration of the term of this Option as set forth in the Notice of Grant.

(b) Method of Exercise. This Option shall be exercisable by written notice (in the form attached hereto as Exhibit A) which shall state the election to exercise the Option, the number of Shares in respect of which the Option is being exercised, and such other representations and agreements as to the holder’s investment intent with respect to such shares of Common Stock as may be required by the Company pursuant to the provisions of the Plan. Such written notice shall be signed by the Optionee and shall be delivered in person or by certified mail to the Secretary of the Company. The written notice shall be accompanied by payment of the Exercise Price. This Option shall be deemed to be exercised upon receipt by the Company of such written notice accompanied by the Exercise Price.

No Shares will be issued pursuant to the exercise of an Option unless such issuance and such exercise shall comply with all relevant provisions of law and the requirements of any stock exchange upon which the Shares may then be listed. Assuming such compliance, for income tax purposes the Shares shall be considered transferred to the Optionee on the date on which the Option is exercised with respect to such Shares.

3. Optionee’s Representations. In the event the Shares purchasable pursuant to the exercise of this Option have not been registered under the Securities Act of 1933, as amended (the “Securities Act”), at the time this Option is exercised, Optionee shall, if required by the Company, concurrently with the exercise of all or any portion of this Option, deliver to the Company an Investment Representation Statement in the form attached hereto as Exhibit B.

4. Method of Payment. Payment of the Exercise Price shall be by any of the following, or a combination thereof, at the election of the Optionee:

a. cash;

b. check; or

12

c. at the discretion of the Board or Committee, any other method permitted by the Plan or any combination thereof.

5. Restrictions on Exercise. This Option may not be exercised until such time as (a) the Plan and the Shares covered by this Option have been approved by the stockholders of the Company and (b) the issuance of such Shares upon such exercise or the method of payment of consideration for such shares does not constitute a violation of any applicable federal or state securities or other law or regulation, including any rule under Part 207 of Title 12 of the Code of Federal Regulations (“Regulation G”) as promulgated by the Federal Reserve Board. As a condition to the exercise of this Option, the Company may require Optionee to make any representation and warranty to the Company as may be required by any applicable law or regulation.

6. Termination of Relationship. In the event of termination of Optionee’s employment or consulting relationship with the Company, Optionee may, to the extent otherwise so entitled at the date of such termination (the “Termination Date”), exercise this Option during the Termination Period set out in the Notice of Grant. To the extent that Optionee was not entitled to exercise this Option at the date of such termination, or if Optionee does not exercise this Option within the time specified herein, the Option shall terminate.

7. Disability of Optionee. Notwithstanding the provisions of Section 6 above, in the event of termination of Optionee’s consulting or employment relationship as a result of his total and permanent disability (as defined in Section 22(e)(3) of the Code or any successor provision), Optionee may, but only within twelve (12) months from the date of termination of employment or consulting relationship (but in no event later than the date of expiration of the term of this Option as set forth in Section 10 below), exercise this Option to the extent Optionee was entitled to exercise it at the date of such termination. To the extent that Optionee was not entitled to exercise the Option at the date of termination, or if Optionee does not exercise such Option (which Optionee was entitled to exercise) within the time specified herein, the Option shall terminate.

8. Death of Optionee. In the event of the death of Optionee during the term of this Option and, with respect to a Consultant, during such Consultant’s continuing consulting relationship with the Company or within 90 days of termination of Consultant’s relationship with the Company and, with respect to an employee, during such employee’s employment relationship with the Company or within 90 days of termination of such employee’s relationship with the Company, the Option may be exercised at any time within twelve (12) months following the date of termination (but in no event later than the date of expiration of the term of this Option as set forth in Section 10 below), by Optionee’s estate or by a person who acquired the right to exercise the Option by bequest or inheritance, but only to the extent of the right to exercise that Optionee was entitled to at the date of death.

9. Nontransferability of Option. This Option may not be transferred in any manner other than by will or by the laws of descent or distribution and may be exercised during the lifetime of Optionee only by Optionee. The terms of this Option shall be binding upon the executors, administrators, heirs, successors and assigns of the Optionee.

10. Term of Option. This Option may be exercised only within the term set out in the Notice of Grant and the Plan, and may be exercised during such term only in accordance with the Plan and the terms of this Option.

11. Taxation Upon Exercise of Option. Optionee understands that, upon exercising a Nonstatutory Stock Option, he or she will recognize income for tax purposes in an amount equal to the excess of the then fair market value of the Shares over the exercise price. If the Optionee is an employee, the Company will be required to withhold from Optionee’s compensation, or collect from Optionee and pay to the applicable taxing authorities an amount equal to a percentage of this compensation income. Additionally, the Optionee may at some point be required to satisfy tax withholding obligations with respect to the disqualifying disposition of an Incentive Stock Option. The Optionee shall satisfy his or her tax withholding obligation arising upon the exercise of a Nonstatutory Stock Option or a disqualifying disposition by one or some combination of the following methods: (i) by cash payment, or (ii) out of Optionee’s current compensation, or (iii) if permitted by the Committee, in its discretion, by surrendering to the Company Shares that (a) in the case of Shares previously acquired from the

13

Company, have been owned by the Optionee for more than six months on the date of surrender, and (b) have a fair market value on the date of surrender equal to or greater than Optionee’s marginal tax rate times the ordinary income recognized, or (iv) if permitted by the Committee, in its discretion, and if the Option is designated as a Nonstatutory Stock Option by electing to have the Company withhold from the Shares to be issued upon exercise of the Option that number of Shares having a fair market value equal to the amount required to be withheld. For this purpose, the fair market value of the Shares to be withheld shall be determined on the date that the amount of tax to be withheld is to be determined (the “Tax Date”).

If the Optionee is subject to Section 16 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) (an “Insider”), any surrender of previously owned Shares to satisfy tax withholding obligations arising upon exercise of this Option must comply with the applicable provisions of Rule 16b-3 promulgated under the Exchange Act (“Rule 16b-3”) and shall be subject to such additional conditions or restrictions as may be required thereunder to qualify for the maximum exemption from Section 16 of the Exchange Act with respect to Plan transactions.

All elections by an Optionee to have Shares withheld to satisfy tax-withholding obligations shall be made in writing in a form acceptable to the Committee and shall be subject to the following restrictions:

(1) the election must be made on or prior to the applicable Tax Date;

(2) once made, the election shall be irrevocable as to the particular Shares of the Option as to which the election is made;

(3) all elections shall be subject to the consent or disapproval of the Committee;

(4) if the Optionee is an Insider, the election must comply with the applicable provisions of Rule 16b-3 and shall be subject to such additional conditions or restrictions as may be required thereunder to qualify for the maximum exemption from Section 16 of the Exchange Act with respect to Plan transactions.

12. Tax Consequences. Set forth below is a brief summary as of the date of this Option of some of the federal tax consequences of exercise of this Option and disposition of the Shares. THIS SUMMARY IS NECESSARILY INCOMPLETE, AND THE TAX LAWS AND REGULATIONS ARE SUBJECT TO CHANGE. OPTIONEE SHOULD CONSULT A TAX ADVISER BEFORE EXERCISING THIS OPTION OR DISPOSING OF THE SHARES.

(a) Exercise of ISO. If this Option qualifies as an ISO, there will be no regular federal income tax liability upon the exercise of the Option, although the excess, if any, of the fair market value of the Shares on the date of exercise over the Exercise Price will be treated as an item of adjustment to the alternative minimum tax for federal tax purposes in the year of exercise and may subject the Optionee to the alternative minimum tax.

(b) Exercise of Nonstatutory Stock Option. If this Option does not qualify as an ISO, there may be a regular federal income tax liability upon the exercise of the Option. The Optionee will be treated as having received compensation income (taxable at ordinary income tax rates) equal to the excess, if any, of the fair market value of the Shares on the date of exercise over the Exercise Price and the Company will qualify for a deduction in the same amount, subject to the requirement that the compensation be reasonable. If Optionee is an employee, the Company will be required to withhold from Optionee’s compensation or collect from Optionee and pay to the applicable taxing authorities an amount equal to a percentage of this compensation income at the time of exercise.

(c) Disposition of Shares. In the case of an NSO, if Shares are held for at least one year, any gain realized on disposition of the Shares will be treated as long-term capital gain for federal income tax purposes. In the case of an ISO, if Shares transferred pursuant to the Option are held for at least one year after exercise and are disposed of at least two years after the Date of Grant, any gain realized on disposition of the Shares will also be treated as long-term capital gain for federal income tax purposes. If Shares purchased under an ISO are disposed of within one-year after exercise or within two years after the Date of

14

Grant, any gain realized on such disposition will be treated as compensation income (taxable at ordinary income rates) in an amount equal to the excess of the lesser of (1) the fair market value of the Shares on the date of exercise, or (2) the sale price of the Shares over the Exercise Price paid for those shares. The Company will also be allowed a deduction equal to any such amount recognized, subject to the requirement that the compensation be reasonable.

(d) Notice of Disqualifying Disposition of ISO Shares. If the Option granted to Optionee herein is an ISO, and if Optionee sells or otherwise disposes of any of the Shares acquired pursuant to the ISO on or before the later of (1) the date two years after the Date of Grant, or (2) the date one year after the date of exercise, the Optionee shall immediately notify the Company in writing of such disposition. Optionee agrees that Optionee may be subject to income tax withholding by the Company on the compensation income recognized by the Optionee from the early disposition by payment in cash or out of the current earnings paid to the Optionee.

13. Restrictive Legends and Transfer Restrictions. Unless the Shares granted hereunder have been effectively registered under the Securities Act of 1933, as now in force or hereafter amended, the Company shall be under no obligation to issue or transfer any shares covered by this option unless the Optionee or Optionee’s successors in accordance with section 5 above, shall give a written representation and undertaking to the company and upon which, in the opinion of such counsel, the Company may reasonable rely that Optionee is acquiring the shares for his or her own account as an investment and not with the view to, or for sale in connection with, the distribution of such shares, and that Optionee will make no transfer of the same except in compliance with any rules and regulations in force at the time of such transfer under the Securities Act of 1933, or any other applicable law, and that if shares are issued or transferred without such registration, a legend to this effect may be placed upon the certificate representing the Shares.

14. Successors and Assigns. The Company may assign any of its rights under this Agreement to single or multiple assignees, and this Agreement shall inure to the benefit of the successors and assigns of the Company. Subject to the restrictions on transfer herein set forth, this Agreement shall be binding upon Optionee and his or her heirs, executors, administrators, successors and assigns.

15. Interpretation. Any dispute regarding the interpretation of this Agreement shall be submitted by Optionee or by the Company forthwith to the Company’s Board of Directors or the Committee that administers the Plan, which shall review such dispute at its next regular meeting. The resolution of such a dispute by the Board or committee shall be final and binding on the Company and on Optionee.

16. Governing Law; Severability. This Agreement shall be governed by and construed in accordance with the laws of the State of North Carolina excluding that body of law pertaining to conflicts of law. Should any provision of this Agreement be determined by a court of law to be illegal or unenforceable, the other provisions shall nevertheless remain effective and shall remain enforceable.

17. Notices. Any notice required or permitted hereunder shall be given in writing and shall be deemed effectively given upon personal delivery or upon deposit in the United States mail by certified mail, with postage and fees prepaid, addressed to the other party at its address as shown below beneath its signature, or to such other address as such party may designate in writing from time to time to the other party.

18. Further Instruments. The parties agree to execute such further instruments and to take such further action as may be reasonably necessary to carry out the purposes and intent of this Agreement.

19. 2004 Stock Plan. Optionee acknowledges receipt of a copy of the Plan and represents that he is familiar with the terms and provisions thereof, and hereby accepts this Option subject to all of the terms and provisions thereof. Optionee has reviewed the Plan and this Option in their entirety, has had an opportunity to obtain the advice of counsel prior to executing this Option and fully understands all provisions of the Option. Optionee hereby agrees to accept as binding, conclusive and final all decisions or interpretations of the Board or Committee upon any questions arising under the Plan or this Option.

INVESTMENT REPRESENTATION STATEMENT

OPTIONEE:
COMPANY:	Chelsea Therapeutics International, Ltd.
SECURITY:	Common Stock
AMOUNT:	Shares

In connection with the purchase of the above-listed Securities, I, the Optionee, represent to the Company the following.

1. Optionee is aware of the Company’s business affairs and financial condition and has acquired sufficient information about the Company to reach an informed and knowledgeable decision to acquire the securities. Optionee is purchasing the securities for investment for Optionee’s own account only and not with a view to, or for resale in connection with, any “distribution” thereof within the meaning of the Securities Act of 1933, as amended (the “Securities Act”).

2. Optionee understands that the securities have not been registered under the Securities Act in reliance upon a specific exemption therefrom, which exemption depends upon, among other things, the bona fide nature of Optionee’s investment intent as expressed herein.

3. Optionee further understands that the securities must be held indefinitely unless subsequently registered under the Securities Act or unless an exemption from registration is available. Moreover, Optionee understands that the Company is under no obligation to register the securities. In addition, Optionee understands that the certificate evidencing the securities will be imprinted with a legend that prohibits the transfer of the securities unless they are registered or such registration is not required in the opinion of counsel for the Company.

4. Optionee is familiar with the provisions of Rules 144, 144(k) and 701, promulgated under the Securities Act, that permit limited public resale of “restricted securities” acquired, directly or indirectly, from the issuer thereof (or from an affiliate of such issuer) in a nonpublic offering, subject to the satisfaction of certain conditions.

Subject to any lock-up agreement, in the event the Company becomes subject to the reporting requirements of Section 13 or 15(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), the securities exempt under Rule 701 may be resold by the Optionee 90 days thereafter, subject to the satisfaction of certain of the conditions specified by Rule 144, including: (a) the sale being made through a broker in an unsolicited “broker’s transaction” or in transactions directly with a market maker (as that term is defined under the Exchange Act); and (b) in the case of an affiliate, the availability of certain public information about the Company, and the amount of securities being sold during any three-month period not exceeding the limitations specified in Rule 144(e), if applicable.

If the purchase of the securities does not qualify under Rule 701 at the time of purchase, then the securities may be resold by the Optionee in certain limited circumstances subject to the provisions of Rule 144, which require: (a) the availability of certain public information about the Company; (b) the resale occurring not less than one year after the party has purchased, and made full payment (within the meaning of Rule 144) for, the securities to be sold; and (3) in the case of an affiliate, or of a nonaffiliate who has held the securities less than two years, the sale being made through a broker in an unsolicited “broker’s transaction” or in transactions directly with a market maker (as that term is defined under the Exchange Act) and the amount of securities being sold during any three-month period not exceeding the specified limitations.

17

If all of the requirements of Rule 144 are not satisfied, Optionee may be able to sell the securities without registration pursuant to the exemption contained in Rule 144(k), provided that the resale occurs not less than two years after the party has purchased, and made full payment (within the meaning of Rule 144) for, the securities.

5. Optionee further understands that at the time Optionee wishes to sell the securities there may be no public market upon which to make such a sale, and that, even if such a public market then exists, the Company may not be satisfying the current public information requirements of Rules 144 or 701, and that, in such event, Optionee would be precluded from selling the securities under Rules 144 or 701 even if the one-year minimum holding period had been satisfied; however, Optionee may be able to sell the securities pursuant to the exemptions contained in Rule 144(k) if the two-year holding period has been satisfied.

6. Optionee further understands that in the event all of the applicable requirements of Rules 144, 144(k) or 701 are not satisfied, registration under the Securities Act or some registration exemption will be required; and that, notwithstanding the fact that Rules 144, 144(k) and 701 are not exclusive, the Staff of the SEC has expressed its opinion that persons proposing to sell private placement securities other than in a registered offering and otherwise than pursuant to Rules 144, 144(k) or 701 will have a substantial burden of proof in establishing that an exemption from registration is available for such offers or sales, and that such persons and their brokers who participate in such transactions do so at their own risk.
