Overview  

PART I  

We are a clinical stage biopharmaceutical company focused on developing and commercializing innovative neuropsychiatric 
therapeutics. Our clinical stage product candidate, ganaxolone, is a small molecule that is a synthetic analog of allopregnanolone, an endogenous 
neurosteriod known for its anticonvulsive and antianxiety activity.  By targeting the same spectrum of GABA 
ganaxolone delivers its therapeutic benefit through a mechanism that we believe may offer safety and efficacy advantages compared to other 
marketed antiepileptic drugs, or AEDs.  Ganaxolone was rationally designed to unlock the potential for chronic neurosteroid therapy through 
modulation of the GABA 
trials and we are conducting the requisite preclinical experiments to ready our intravenous, or IV, dose form for clinical use. We have a dual 
strategy of evaluating ganaxolone for treating seizure disorders, and treating targeted orphan diseases for which there are no approved therapies, 
the development timelines may be abbreviated, and for which there is a strong mechanistic rationale for ganaxolone to offer therapeutic benefit to 
patients with very high unmet needs.  

 receptor.  Our orally administered solid and liquid suspension dose forms are being evaluated in our ongoing clinical 

 receptors as allopregnanolone,

Our Pipeline  

We are developing ganaxolone for multiple epilepsy and other neuropsychiatric indications, including the following:  

Our most advanced indication for ganaxolone is as an adjunctive, or add-on, therapy for the treatment of partial, also known as focal, 

onset seizures in adults with epilepsy. Phase 3 randomized multinational clinical trial utilizing our oral capsules is underway for this indication.  
We plan to release top line data by the first quarter of 2016.  We have completed a Phase 2 clinical trial in 147 patients with focal onset seizures 
where we demonstrated that patients who added ganaxolone liquid suspension to their medication regimen experienced a statistically significant 
reduction in seizures as compared to patients who added placebo.  

Based upon both proof-of-concept data for ganaxolone in the treatment of refractory pediatric seizures and a mechanistic rationale for 

providing a therapeutic benefit through increased GABAergic signaling, we have initiated an open-label Phase 2 clinical trial evaluating 
ganaxolone for treatment of the orphan disease, PCDH19 female pediatric epilepsy.  We expect to release initial data from this study during 2015.

We are developing an IV formulation for use in the hospital setting to control acute seizures.  We are conducting the requisite preclinical 

experiments to ready our IV formulation for clinical use.  

In addition to anticonvulsive activity, we believe ganaxolone’s mechanism may improve anxiety and behaviors related to anxiety, such as 

irritability or social withdrawal. Ganaxolone is being evaluated in an investigator-sponsored, grant funded, randomized double-blind placebo-
controlled Phase 2 crossover study as potential proof-of-concept in treating behaviors in Fragile X Syndrome, or FXS, which we believe to be an 
orphan indication.  We plan to complete this study during 2015.  

Ganaxolone Mechanism of Action  

The effects of allopregnanolone have been studied for over two decades and its role in controlling seizures and improving anxiety, mood 

A 

 type receptors is well documented. Despite these positive characteristics, we believe 

and sleep through positive modulation of GABA 
allopregnanolone is not suitable for chronic use due to potential undesired hormonal side effects. Ganaxolone was designed to have the same 
GABA modulation effects as allopregnanolone without these hormonal side effects. Ganaxolone and allopregnanolone differ from other GABA 
agents by interacting with unique binding sites on the GABA 
GABA synapse. Ganaxolone’s activation of the extrasynaptic receptor is a unique mechanism that provides stabilizing effects that we believe 
differentiates it from other drugs that increase GABA signaling. Preclinical studies provide evidence that the GABA modulatory activity of 
ganaxolone is responsible for its anticonvulsive activity in epileptic seizures and its antianxiety effects in FXS and other neuropsychiatric 
disorders.

Ganaxolone in Epilepsy  

Overview and Treatment of Epilepsy  

Epilepsy is characterized by seizures that arise from abnormal electrical discharge in the brain, resulting in alterations of consciousness, 

involuntary movement, or altered sensations. Seizures in epilepsy may be related to a brain injury or heredity, but often the cause is unknown. 
Epileptic seizures are generally described in two major groups, primary generalized seizures and focal onset seizures. Primary generalized seizures 
begin with a widespread electrical discharge that involves both sides of the brain at once. Focal onset seizures begin with an electrical discharge in 
one limited area of the brain. Generally, a person is diagnosed as having epilepsy when they have had at least two seizures that do not have a self-
limiting cause such as a high fever.  

In 2012, Decision Resources reported that approximately five million people were under treatment for epilepsy in the United States, 

Europe and Japan. IMS Health reported that global sales of AEDs were approximately $14 billion in 2011. It is estimated that approximately 3.8% 
of people will develop epilepsy during their lifetime,  

2  

   
   
   
   
   
  
   
   
   
   
   
 
Table of Contents  

with a higher incidence in men than women. New cases of epilepsy are most common among children, especially during the first year of life. The 
rate of new cases gradually declines until about age 10, and then becomes stable. Remission is common for children as they age. After age 55 to 
60, the rate of new epilepsy cases starts to increase, as people develop strokes, brain tumors, or Alzheimer’s disease.  

Newly diagnosed epilepsy patients are treated with daily administration of an AED. Approximately 60% of patients will achieve an 

adequate level of seizure control with a single AED, and the remainder will resort to polypharmacy. Approximately 30 to 35% of all patients do 
not reach an acceptable level of seizure control even with polypharmacy, and are considered to be refractory cases. We estimate that the market 
opportunity for this refractory patient population, which will be ganaxolone’s initial target segment, will exceed $4 billion in the United States, 
Europe and Japan. Despite the widespread availability of generic drugs for the treatment of epilepsy, in many countries, including the United 
States, health payors permit these epilepsy patients to switch to costlier medications or polypharmacy in order to gain seizure control or reduce 
side effects. Our market research suggests that many physicians attempt to add a medication with a new mechanism of action while also trying to 
minimize side effect burden when selecting a substitute or add-on AED. A subset of focal onset seizure patients who cannot gain acceptable 
seizure control through pharmacologic treatment options resort to implantable devices or removal of the part of the brain causing the seizures.  

Market Opportunity  

Epileptic seizures require chronic treatment, often over a lifetime. Available AEDs are efficacious for many patients, but chronic 
treatment is complicated by side effects, including cardiovascular risks, liver enzyme induction, kidney stones, behavioral changes, sedation and 
adverse effects on cognitive function, drug tolerance, and reproductive risk.  

Women have the added complication that several currently available AEDs increase the risk to the fetus, including birth defects, lowered 

IQ and low birth weight. Most of these drugs are categorized by the U.S. Food and Drug Administration (FDA) as Pregnancy Category C, 
indicating a potential risk to the fetus, and three of these drugs (valproate, carbamazepine, phenytoin) have been classified as Pregnancy 
Category D, indicating that use is only justified if there is a serious condition where the need outweighs risk to the fetus based on registry data.  

Despite the many available AEDs, approximately 30 to 35% of patients do not attain acceptable seizure control either with single drug or 

multiple drug therapy. Furthermore, medications with significant side effects or dosing regimens that undermine compliance make it difficult for 
patients to achieve and maintain seizure free status. For these reasons there is a need for new AEDs with novel mechanisms of action and 
improved side effect profiles that can maintain seizure control with chronic administration for people with refractory epilepsy. The recent 
successful introduction of Vimpat by UCB is an example of market acceptance of a new AED with a novel mechanism. Vimpat was approved in 
the United States and European Union in 2008, and achieved global sales of approximately €471 million  in 2014. Several other successfully 
marketed AEDs experienced similar sales levels with similar duration of time on the market. UCB has stated that it expects Vimpat to achieve 
over €1.2 billion in peak sales globally.  

Our Solution  

We believe ganaxolone to be a first-in-class therapy with potential to provide meaningful treatment advantages for adults with focal onset 

seizures who do not achieve adequate seizure control from, have developed tolerance to, or have safety concerns with currently available 
medications. We believe ganaxolone, if approved, may provide the following benefits for patients:  

•                   Efficacy for refractory patients with focal onset seizures.  Our completed Phase 2 clinical trial in patients with refractory focal 

onset seizures demonstrated that patients who added ganaxolone to their medication regimen experienced a statistically significant 
reduction in seizures as compared to patients who added placebo.  

•                   Improved safety and tolerability profile.  Ganaxolone was engineered to be a synthetic analog of a natural molecule, 

allopregnanolone. Completed preclinical safety studies and Phase 1 and 2 clinical trials involving approximately 1,000 subjects show 
ganaxolone to be generally safe and well-tolerated, without evidence of toxicity to heart, liver, blood or other body systems and 
without many of the side effects common to other AEDs. We believe this safety profile may make ganaxolone a treatment of choice 
in antiepileptic polypharmacy regimens.

Table of Contents  

•                   Improved reproductive toxicity profile.  Based on ganaxolone’s mechanism, and preclinical and clinical findings to date, we believe 
ganaxolone will offer a lower risk for reproductive toxicity than many currently available AEDs, which we believe would be an 
important safety differentiator for women of childbearing age.  

Our market research with physicians indicates neurologists and epilepsy specialists would expect to use ganaxolone in 16 to 29% of their 

focal onset seizure patients.

Clinical Trials for Epilepsy in Adults  

Controlled Phase 2 Clinical Trial for Adjunctive Treatment of Drug- Resistant Focal Onset Seizures (Study 600)  

We successfully completed a double-blind, randomized, placebo-controlled, Phase 2 clinical trial in the United States of ganaxolone as 
an adjunctive treatment in patients with refractory focal onset seizures. In this trial, ganaxolone satisfied the primary efficacy endpoint and was 
considered to be generally safe and well tolerated. The study enrolled 147 patients who had been diagnosed with epilepsy on average 25 years 
prior and 75% of which were taking two or three AEDs to control seizures before they entered the study. Subjects were treated for ten weeks with 
placebo or ganaxolone as adjunctive treatment to existing therapy and recorded their seizures daily in a diary. Mean baseline seizure frequency 
was 6.5 and 9.2 seizures per seven days in the ganaxolone and placebo groups, respectively. Subjects gradually increased their daily dose up to 
1,500 milligrams per day, or mg/day, over the first two weeks, known as titration or the titration period, followed by maintenance dosing at 1,500 
mg/day for eight weeks, known as the maintenance period. The primary efficacy endpoint was change from baseline in weekly seizure frequency. 
Results of the analysis, using a statistical test (Kruskal-Wallis) that is employed when data have non-normal distribution, are presented in the table 
below:

+2.0% (63.2)    
-10.2%    

Difference  

19.6 %  
15.7 %  

In the intention-to-treat, or ITT, population, which included all study subjects who took at least one dose of study medication, there was a 

statistically significant reduction in the percent change in mean weekly seizure frequency in the ganaxolone group, which decreased 17.6% from 
baseline at week 10, whereas in the placebo group, mean weekly seizure frequency increased by 2% compared to baseline at week 10, a difference 
of 19.6% (p=0.014). The p-value represents the probability that the difference between the two groups is due to chance rather than drug effect, and 
when that probability is less than 5%, or p<0.05, the result is considered statistically significant. In the ganaxolone group median seizure 
frequency decreased by 26.0%, whereas in the placebo group median seizure frequency decreased by 10.2%, a difference of 15.7%. We believe 
this effect size for an adjunctive treatment of a highly refractory patient population is consistent with the Phase 2 results for other AEDs that 
ultimately received FDA approval.  

Secondary analyses included the analysis of the percentage of subjects with greater than or equal to 50% improvement from baseline, or 
responder analysis, mean and percent change in seizure frequency from baseline, number of seizure-free days and seizure-free subjects, change in 
seizure frequency by week, and change from baseline in types of seizures. In general, the results of secondary efficacy analyses supported the 
primary outcome that subjects treated with ganaxolone showed improved seizure control compared to those treated with placebo. The responder 
analysis is considered by the EMA to be the primary analysis of a registration trial. In this study, the percent of responders in the ganaxolone 
group compared to the placebo group in the ITT population were 23.5% and 14.6% (p=0.192) for the titration plus maintenance period, and 26.3% 
v. 13.0% (p=0.057) for the maintenance period. No gender effect or effect of concomitant medication was observed.  

Open Label Extension of Controlled Phase 2 Clinical Trial for Adjunctive Treatment of Drug-Resistant Focal Onset Seizures (Study 601) 

Of the treatment-resistant subjects in our Phase 2 clinical trial, 95% of eligible subjects continued in a long-term open-label extension 

where the mean duration of treatment was 39 weeks. The objective of the open-label extension study was to evaluate the long-term safety, 
tolerability and efficacy of ganaxolone at a target dose of 1,500 mg/day. The primary endpoint was change in seizure frequency at endpoint 
compared to baseline of the double-blind study, presented as mean and median change. Secondary assessments were similar to those evaluated in 
the blinded portion of the study.  

The mean and median percent reductions in weekly seizure frequency were 14.2% and 23.2% from baseline to endpoint, respectively. In 
total, 70% of subjects had a reduction in seizure frequency during the study. Importantly, subjects previously randomized to placebo in the double-
blind study (Study 600) that were switched to ganaxolone in the open-label study showed mean and median reduction in seizure frequency 
comparable to patients randomized to ganaxolone in the double-blind study.

Secondary analyses included assessment of responders and seizure free status. Twenty-four percent of subjects met responder criteria at 
endpoint, defined as a reduction in seizures of 50% or more from baseline, while 43% of those who remained in the study for 52 weeks or more 
met 50% responder criteria. Subjects in the study reported a mean increase in number of seizure-free days per week of 17.4%, an increase that we 
believe to be meaningful in the context of the severity and persistence of epilepsy in this drug-resistant population.  

Phase 2 Clinical Trial of Monotherapy in Drug Resistant Focal Onset Seizures (Study 104)  

A controlled clinical trial was also conducted to evaluate ganaxolone as monotherapy for focal onset seizures in a drug-resistant 
population. This double-blind, randomized, placebo-controlled, Phase 2 clinical trial enrolled 52 subjects who were withdrawn from their 
antiepileptic medications prior to evaluation for surgical treatment of their seizures. The subjects were treated with ganaxolone monotherapy 625 
mg three times per day for eight days. The primary efficacy measure was duration of treatment prior to study withdrawal, due to emergence of 
seizures, as measured from day 2 of the study.  

As depicted in the plot above showing the Kaplan-Meier survival function of subjects remaining in the study, 62% of subjects in the 
placebo group left the study due to emergence of seizures by day 8, compared with 39% of ganaxolone subjects (p=0.08). Statistical testing of 
completion rates between the two groups found a statistically significant difference between completion rates in the two groups, with 50% of 
ganaxolone subjects completing the study compared to 25% of placebo subjects (p=0.04).  

Ganaxolone Safety Overview  

More than 1,000 subjects have received treatment with ganaxolone ranging in duration from one day to more than two years using doses 
from 50 to 2,000 mg/day. A total of 289 healthy subjects received ganaxolone doses of 50 to 2,000 mg/day in Phase 1 studies, for periods of up to 
two weeks. In the completed Phase 2 clinical studies, 697 unique subjects have received ganaxolone including 135 pediatric subjects with 
epilepsy, 169 adult subjects with epilepsy, and 393 adult subjects with migraine. Ganaxolone was administered in Phase 2 studies to pediatric 
subjects at doses up to 54 mg/kg and to adult subjects at doses up to 1,875 mg/day. No drug-related deaths occurred in any of these clinical trials, 
and the majority of adverse events were not medically serious and resolved upon discontinuation of therapy. In the ganaxolone safety database 
there are no trends of medically important changes in blood chemistry, vital signs, liver function, renal function or cardiovascular parameters in 
the adult or pediatric populations.  

We have completed preclinical safety pharmacology and toxicology testing, including reproductive toxicology. Animal pharmacokinetic 
and in vitro studies show that ganaxolone is primarily metabolized by the CYP3A family of liver enzymes, a common route of drug metabolism. 
All in vitro studies have shown ganaxolone has low potential for interaction with other drugs at several multiples of observed human ganaxolone 
levels. Furthermore, neither ganaxolone nor its metabolites have a ketone ring at the 3-position, a requirement for hormonal activity. In binding 
studies, ganaxolone has no appreciable affinity for estrogen or progesterone receptors. We found no evidence of changes in blood, liver, kidney or 
the gastrointestinal systems indicating functional or anatomical adverse effects associated with either single- or multiple-dose treatment with 
ganaxolone in preclinical safety pharmacology studies, nor have we seen evidence of any end organ toxicity from human clinical studies. We have 
not detected potential for ganaxolone to cause cellular mutations or carcinogenicity in studies to date. We plan to initiate the final two-year 
carcinogenicity studies in rats and mice in 2015.  

In reproductive toxicology studies, ganaxolone did not cause any malformations of the embryo or fetus in rats or mice and did not 

significantly affect the development of offspring. No changes in sperm parameters were found. We believe these findings are important as all 
currently marketed AEDs have shown developmental toxicities in animal studies such as fetal death or skeletal abnormalities, generating a rating 
of Pregnancy Category C that indicates a finding of developmental toxicities in animal studies. Valproate, carbamazepine, phenytoin and 
topiramate have been linked with birth defects in humans, for example, head and facial malformations, and lowered birth weight, at a rate higher 
than observed in women who did not take these drugs. This association has resulted in a categorization of Pregnancy Category D for these drugs, 
indicating positive evidence of human fetal risk based on scientific data. Based on ganaxolone’s mechanism and preclinical and clinical findings 
to date, we intend to seek differentiated labeling including a designation of FDA Pregnancy Category B for ganaxolone, which indicates animal 
reproduction studies have failed to demonstrate a risk to the fetus, which we believe would be an important safety differentiator for women of 
childbearing age.

Clinical Safety Results in Epilepsy  

Ganaxolone was considered to be generally safe and well tolerated in the Phase 2 adjunctive treatment trials in adults with focal onset 

seizures. The majority of adverse events associated with ganaxolone treatment were related to known CNS effects of GABA, were not medically 
serious and resolved upon discontinuation of therapy. The data did not show any trends of medically important changes in blood chemistry, vital 
signs, liver function, renal function or cardiovascular parameters related to ganaxolone treatment.  

The most frequent treatment-emergent adverse events, or TEAEs, observed in Study 600 are presented in the table below.

The two treatment groups had similar rates of discontinuation due to adverse events (7% ganaxolone, 6% placebo) and similar rates of 
serious adverse events, or SAEs (5% ganaxolone, 8% placebo), mostly related to the underlying epilepsy. The majority of TEAEs resolved with 
continued treatment or dose reduction. In contrast to some marketed AEDs, the incidence of behavioral TEAEs (reported as depression, insomnia, 
affective disorder, confusional state, affect lability, aggression, anxiety) was similar in the ganaxolone and placebo treatment groups.  

Ganaxolone continued to be considered generally safe and well tolerated in the long-term open-label extension, Study 601, in which 120 
subjects received ganaxolone for a mean duration of 39 weeks. The most common adverse events considered related to ganaxolone treatment were 
fatigue (14%), dizziness (9%) and somnolence, also known as sleepiness (7%). Eleven percent of the subjects discontinued due to one or more 
adverse events. One SAE out of 17 reported was considered related to ganaxolone treatment, a 59 year old female on 900 mg/day whose liver 
enzymes were elevated after 57 days of treatment. The enzyme levels returned to normal with a reduction in dose to 600 mg/day. In this long-term 
open-label study of ganaxolone for adjunctive treatment of focal onset seizures, no new safety concerns were identified during extended treatment 
with doses up to 1,500 mg/day.  

In Study 104, the eight-day monotherapy study of ganaxolone and placebo in presurgical patients, ganaxolone was generally well-
tolerated and the profile of adverse events between the two groups was similar. Dizziness, which was reported in four ganaxolone and three 
placebo subjects, was the most frequent adverse event. One SAE was reported in each group; the ganaxolone subject experienced severe agitation 
and depression while the placebo subject experienced postictal psychosis. As in the other studies, no clinically meaningful differences between 
treatment groups were noted in laboratory, vital sign, electrocardiogram, or physical/neurological exam results.  

Ongoing and Planned Clinical Trials in Epilepsy  

In October 2013 we initiated an international, randomized, placebo-controlled, Phase 2b clinical trial in adult subjects for adjunctive 

treatment of focal onset seizures (Study 603). In Cohort 1, approximately 50 subjects were randomized to receive either placebo or ganaxolone 
capsules in a step titration of 1,200 mg/day for four weeks followed by 1,800 mg/day for four weeks. Blood levels of ganaxolone will be assessed 
at steady state for each dose level. Subjects from both cohorts enter a one year open label period after the double-blind treatment period.  

The study protocol was then amended to meet the requirements for a phase 3 study and Cohort 2 was added to the protocol. In Cohort 2, 

an additional 300 subjects are being randomized to receive either placebo or

1,800 mg/day of ganaxolone for 12 weeks. Cohort 2 is intended to meet the Phase 3 design and statistical power requirements and precedents for 
the FDA and other regulatory bodies for consideration as one of our adequate and well-controlled studies as part of an FDA or EMA filing 
package for registration. The primary endpoint of this trial is change in seizure frequency per month compared to baseline of Cohort 2 subjects 
after 14 weeks of treatment, at the end of the blinded phase of the study. We are capturing adverse events and other measures of safety as well as 
responder rate, seizure-free status and changes in seizure subtypes. We plan to release top line data in the first quarter of 2016.  

We are planning to conduct a second Phase 3, double-blind, randomized fixed-dose study to confirm the efficacy, tolerability and safety 

of ganaxolone for adjunctive treatment of focal onset seizures in adults. This study, per European guidelines and United States precedents, will 
enroll similar patients as those in our ongoing trial: adult outpatients with drug-resistant focal onset seizures who require add-on therapy in 
addition to their current AEDs. The study will contain two or three fixed dose arms of ganaxolone versus placebo for 12 weeks of maintenance 
therapy. Change in seizure frequency compared to baseline will be the primary outcome measure. Patients who complete the study would be 
eligible to enroll in a one year open-label extension.  

Ganaxolone is currently formulated as an oral suspension and as a capsule. Study 600 and 601 were conducted with an oral suspension 

formulation and Study 603 is being conducted with a capsule formulation. Pharmacokinetic studies are being planned to establish relative potency 
between the capsule and the suspension.  Separate pharmacokinetic studies suggest that the capsule is approximately 20% more potent than the 
suspension.  

Ganaxolone in PCDH19 Female Pediatric Epilepsy - An Orphan Disease  

Overview of PCDH19 Female Pediatric Epilepsy  

PCDH19 female pediatric epilepsy (PCDH19-FPE) is a rare and serious epileptic syndrome characterized by early-onset cluster seizures, 
cognitive and sensory impairment of varying degrees, and psychiatric and behavioral disturbances. The epileptic disorder is an X-linked condition 
caused by a missense mutation in the PCDH19 gene, which encodes for a calcium dependent cell-cell adhesion molecule that is expressed in the 
central nervous system (hippocampus, cerebral cortex, thalamus, amygdala) and which appears to be related to synaptic transmission and 
formation of synaptic connections during brain development. The mean age of onset of this condition is approximately 10 months (range of three-
38 months). There is a genetic test available to determine whether or not a child has the PCDH19 mutation. Although formal epidemiologic data is 
not available, results from diagnostic screenings indicate that approximately 10% of girls who have seizure onset before five years of age have 
PCDH19 mutations. We estimate the PCDH19 population to be approximately 15,000 to 30,000 patients in the United States. These patients 
typically experience multiple types of seizures, including focal and generalized, as well as clusters of seizures that can last from one day to weeks. 
Many of these patients will experience developmental delay, intellectual disability and behavioral problems. Seizures often improve in 
adolescence, although developmental complications persist. Currently, there are no approved therapies for PCDH19-FPE.  

Mechanism of Action  

PCDH19 female pediatric epilepsy is caused by a mutation in the PCDH19 gene. This mutation results in impairment of GABAergic 

signaling both at the agonist and receptor levels. There is also indirect evidence linking progesterone/allopregnanolone to the onset and offset of 
seizures in girls with PCDH19-FPE.  It has been hypothesized that disturbances in certain neurosteroid hormones, such as allopregnanolone, may 
be implicated in the molecular pathogenesis of PCDH19-FPE. We believe that ganaxolone may be useful in the treatment of PCDH19 female 
pediatric epilepsy because it is a synthetic analog of allopregnanolone that can be used to increase GABAergic signaling in these patients. We also 
believe that data from our previously conducted studies of pediatric seizure disorders, which demonstrated ganaxolone’s ability to treat multiple 
seizure types and showed a safety profile similar to that seen is adults, supports our rationale to pursue this rare disease as PCDH19 female 
pediatric patients may experience varying types of seizures.  

Ongoing Clinical Trial in Patients with PCDH19 Female Pediatric Epilepsy  

Based upon both proof-of-concept data for ganaxolone in the treatment of refractory pediatric seizures and a mechanistic rationale for 

providing a therapeutic benefit through increased GABAergic signaling we have initiated an expanded access protocol under our epilepsy 
investigational new drug application (IND) for an open label trial. This proof-of-concept Phase 2 trial is designed to enroll approximately 10 
female pediatric patients between the ages of 2 and 10 years old, with a confirmed PCDH19 genetic mutation. After establishing baseline seizure 
frequency, patients will be treated with  

8  

   
   
   
   
   
   
   
   
   
   
   
 
Table of Contents  

ganaxolone administered as either oral liquid suspension or capsules for up to 26 weeks.  The primary endpoint of the study is percent change in 
seizure frequency per 28 days relative to baseline. We plan to release initial data from this study during 2015.  

Clinical Trial in Refractory Pediatric Epilepsy  

We also conducted an open-label clinical trial to evaluate ganaxolone as add-on therapy in children with refractory epilepsy of multiple 
seizure types including focal, absence, epileptic spasms, tonic and tonic-clonic. Forty-five subjects aged 1-13 years were treated at doses of up to 
12 mg/kg, three times per day. Of the 29 subjects in the study at Week 8, the primary endpoint, twelve (41%) met responder criteria of having 
50% or greater improvement from baseline.  

Ganaxolone in Fragile X Syndrome, or FXS - An Orphan Disease  

Overview and Treatment of FXS  

FXS is a genetic condition that causes intellectual disability, behavioral and learning challenges and various physical characteristics. The 
impairment can range from learning disabilities to more severe cognitive or intellectual disabilities. According to the Centers for Disease Control 
and Prevention, FXS affects 1 in 3,600 to 4,000 males and 1 in 4,000 to 6,000 females of all races and ethnic groups. Approximately 1 in 151 
women carry the Fragile X gene and could pass it to their children. Approximately 1 in 468 men carry the Fragile X gene and their daughters will 
also be carriers. Patients with FXS exhibit autism-like symptoms including cognitive impairment, anxiety and mood swings, attention deficit and 
heightened stimuli. Approximately 7% of women and 18% of men with FXS have seizures. People with FXS are affected throughout their lives. 
Currently, there are no known cures or approved therapies for FXS. Special education and symptomatic treatments are employed to lessen the 
burden of illness.  

Market Opportunity  

Approximately one million individuals in the United States have, or are at risk for developing, a Fragile X associated disorder, with 

approximately 100,000 people having FXS. Treatment approaches focus primarily on supportive care and medications addressing development 
delays, learning disabilities, and social and behavioral problems caused by the disease. Various classes of medications are used to treat behavioral 
and mental health conditions associated with FXS. Some patients with FXS benefit from medications that treat attention deficient disorders. Other 
patients who experience general anxiety, social anxiety and other chronic conditions may benefit from different types of anti-anxiety medications 
and other neuropsychiatric treatments.  

Mechanism of Action  

FXS arises from a mutation of a gene known as the fmr1 gene in the coding for the Fragile X mental retardation protein. In a mouse 

model of this gene mutation, certain brain regions show lower levels of the extrasynaptic GABA 
enzymes responsible for GABA function. The result of fewer GABA 
seizures. Ganaxolone and other agents that have been shown to improve GABA function have also been shown to improve FXS symptoms in this 
mouse model. As FXS symptoms may be diagnosed as early as infancy, it would be beneficial for a drug approved to treat FXS to have a safety 
profile acceptable for use in children as well as adults.  

 receptors in these mice include over-sensitivity to noise, anxiety, and 

 receptors and reduction of proteins and 

A

We believe that ganaxolone, with its high-affinity for extrasynaptic GABA 

 receptors, may increase signaling at existing receptors to 

A 

normalize GABA function thereby reducing anxiety, hyperactivity and other disabilities associated with this inherited disorder.  

Ongoing Clinical Trial (Study 800)  

The MIND Institute at the University of California, Davis has been awarded a medical research grant from the DoD to study ganaxolone 

for treatment of behaviors in FXS in children and adolescents. The MIND Institute, in collaboration with Marinus, is conducting a randomized, 
placebo-controlled, Phase 2 proof-of-concept clinical trial at UC Davis and a site in Belgium.  Approximately 60 subjects will be enrolled and 
titrated up to a maximum dose of 1,800 mg/day of ganaxolone or placebo over a two-week period followed by four weeks of treatment. At the end 
of the first treatment period and following a washout period, subjects are crossed over to the other treatment for a similar two-week titration period 
followed by four weeks of treatment.

Table of Contents  

The primary outcome measure of the study is Clinical Global Impression Rating Scale for Improvement. Secondary outcome measures 

include the Aberrant Behaviors Checklist and ratings scales for specific behaviors associated with childhood FXS. We plan to complete this study 
during 2015.  

Other Potential Future Development Programs for Ganaxolone  

We believe that due to its mechanism of action, there is a rationale for ganaxolone therapy to provide a clinical benefit in a broad array of 
indications beyond our current trials. Such additional indications may include generalized anxiety disorder, PTSD, addictive disorders, catamenial 
epilepsy, perinatal depression, ADHD, and other neurodegenerative disorders. Additionally ganaxolone might be useful in several rare genetic 
disorders related to impaired GABA function such as the orphan indications Neimann Pick Disease, Type C, or status epilepticus. We would need 
to conduct additional clinical trials in order to obtain labeled indications for any of these programs.  

The Injury and Traumatic Stress Consortium, or INTRuST, a group of PTSD treatment centers in the United States, has received 
government funding from the US Department of Defense to evaluate new treatments for PTSD. In collaboration with Marinus, INTRuST 
conducted a proof-of-concept study of ganaxolone versus placebo in adults with PTSD. The Phase 2 clinical trial was conducted at seven Veterans 
Administration centers in the United States. The study enrolled 114 adults with PTSD who were treated for six weeks with ganaxolone at 400-
1200 mg per day or placebo in ascending doses followed by six weeks on open label ganaxolone.  

The primary efficacy measure is the Clinician-Administered PTSD Scale, or CAPS, the standard rating assessment in treatment studies 
for PTSD, measured at the end of week 6. The CAPS measures levels of repetitive thoughts, startle, vigilance, avoidance and depression that are 
the main characteristics of PTSD. Additional efficacy ratings include measures of resilience, sleep, mood and overall global improvement. 
Treatment has been completed in this study. While the primary efficacy endpoint was not met in this study, some evidence of efficacy was seen in 
patients at the highest dose.  Periodic reviews of the safety data from the study showed ganaxolone was safe in this population.  While PTSD is 
not an indication that is part of our core development strategy, we may continue to work with third parties to fund and conduct future clinical 
trials.  

Our Strategy  

Our goal is to maximize the value of ganaxolone as a first-in-class innovative neuropsychiatric therapy with a portfolio of diversified 

indications. The key elements of our strategy to achieve this goal include:  

•                   Executing our registration studies and pursue regulatory approval for ganaxolone for adjunctive treatment of focal onset 
seizures and other epilepsy indications. Building on efficacy established in our two completed Phase 2 clinical trials, and a 
differentiated safety profile as demonstrated in extensive preclinical studies and trials in more than 1,000 subjects, we are executing 
a clinical program to support a registration filing for ganaxolone for adjunctive treatment of focal onset seizures in adults in the 
United States, Europe and other major markets. Additionally, if the results from our adjunctive focal onset seizure trials are positive, 
we plan to develop ganaxolone in other segments of the epilepsy market including for monotherapy and pediatric epilepsy. As a 
result of its efficacy and safety profile, we believe ganaxolone could be a meaningful treatment for epilepsy patients who do not 
achieve adequate seizure control from, have developed tolerance to, or have safety concerns with currently available therapies 
including concerns around reproductive toxicity.  

•                   Pursuing orphan disease epilepsy indications for ganaxolone .   Within epilepsy, there are several smaller patient populations 
where a genetic marker associated with the syndrome has been identified that is linked to deficits in GABAergic signaling. 
Increasing GABAergic tone with ganaxolone, a positive allosteric modulator of GABA receptors, might provide benefit. These small 
populations have the potential for more efficient paths to regulatory approval and commercialization.  A proof-of-concept open label 
Phase 2 clinical trial is ongoing for ganaxolone in patients with PCDH19-FPE.  We may explore development of ganaxolone in other 
rare disease epilepsy indications.  

•                   Broadening dose forms to acute care setting .  Our present ongoing clinical trials utilize our patented nanoparticulate composition 
administered in oral capsule and liquid suspension dose forms.  As a complement to these orally administered dose forms, we are 
conducting the requisite preclinical experiments to ready our intravenous dose form for clinical use.  We plan to evaluate ganaxolone 
IV for the acute care setting for in-hospital use and in patient populations that may benefit from both inpatient ganaxolone IV and an 
outpatient oral form for chronic administration.  

10  

   
   
   
   
   
   
   
   
   
   
   
 
Table of Contents  

•                   Expanding non-epilepsy indications for ganaxolone.  Due to its mechanism of action, we believe ganaxolone has potential for 

therapeutic benefit in a variety of neuropsychiatric disorders in addition to epilepsy. Evidence from preclinical and clinical studies 
demonstrates that treatment with an agent similar to naturally occurring allopregnanolone could be of benefit in patients with 
anxiety, mood, sleep and developmental disorders. A proof-of-concept clinical trial is ongoing for ganaxolone in patients with FXS. 
We may explore development of ganaxolone in other neuropsychiatric disorders and rare disease neurology indications.  

•                   Commercializing ganaxolone in the United States either alone or in collaboration with others.  We intend to build sales and 
marketing infrastructure to reach high-prescribing neurologists and epilepsy specialists in the United States. We may seek co-
promotion partners for our sales efforts to reach other United States physician groups, such as primary care physicians. We believe a 
focused sales and marketing organization could be leveraged to market ganaxolone in other neurology or psychiatry indications if we 
are able to obtain regulatory approval for those other indications.  

•                   Establishing collaborations to develop and commercialize ganaxolone in territories outside the United States. We believe that 
there is significant market opportunity for ganaxolone in epilepsy and other neurological and psychiatric conditions outside of the 
United States. In order to capitalize on this opportunity, we may seek collaborations with pharmaceutical companies that have 
greater reach and resources by virtue of their size and experience in markets outside the United States.  

Intellectual Property  

The proprietary nature of, and protection for our product candidates and discovery programs and know-how are important to our 

business. We have sought patent protection in the United States and internationally for ganaxolone and use of ganaxolone nanoparticles in oral 
solid and liquid dose formulations. Our policy is to pursue, maintain and defend patent rights whether developed internally or licensed from third 
parties and to protect the technology, inventions and improvements that are commercially important to the development of our business.  

The basis of our intellectual property was the discovery of a novel composition of nanoparticles and complexing agents that deliver 
consistent exposure and improved stability of ganaxolone. This discovery resulted in the issuance of United States and foreign patents, which 
cover use of these complexed ganaxolone nanoparticles in oral solid and liquid dose formulations. Our patent portfolio contains seven United 
States patents, two pending United States patent applications, and corresponding foreign patents and patent applications directed to solid and 
liquid ganaloxone formulations and methods for the making and use thereof. These patents expire in 2026, excluding accounting for possible 
patent term extension under the Drug Price Competition and Patent Term Restoration Act of 1984, or the Hatch-Waxman Act, or for possible 
pediatric exclusivity. Corresponding foreign patents have been granted in Australia, Canada, Eurasia, Japan, Mexico, New Zealand, Singapore and 
South Korea. Corresponding foreign patent applications are pending in China, Europe, India, Israel, Japan, Mexico, and South Africa. We have 
not licensed any rights to practice these patents in any of these territories. Pursuant to our agreement with Domain Russia Investments Limited, or 
DRI, we have assigned patent rights, which rights were subsequently assigned to NovaMedica LLC, whereby we licensed our patents, along with 
the rights to develop and commercialize ganaxolone, in Russia and certain other eastern European nations.  

Our patent portfolio also contains patents issued in Australia, United States, Europe and New Zealand covering our novel and cost 

effective ganaxolone synthesis process, which expire in 2030, excluding accounting for possible patent term extension under the Hatch-Waxman 
Act, or for possible pediatric exclusivity. Corresponding foreign patent applications are pending in Brazil, Canada, China, Eurasia, Hong 
Kong, Israel, India, Japan, Mexico, New Zealand and South Korea. We continue to prosecute applications in additional geographies.  

We filed a provisional application in February 2015 directed to intravenous ganaxolone formulations and methods of using these 
formulations to treat refractory epileptic seizures and other disorders.  If granted, this patent will expire in 2036, excluding accounting for possible 
patent term extension under the Drug Price Competition and Patent Term Restoration Act of 1984 or the Hatch-Waxman Act.  

In addition to patents, we rely upon unpatented trade secrets, know-how and continuing technological innovation to develop and maintain 

a competitive position. We seek to protect our proprietary information, in part, through confidentiality agreements with our employees, 
collaborators, contractors and consultants, and invention assignment agreements with our employees and some of our collaborators. The 
confidentiality agreements are  

11  

   
   
   
   
   
   
   
   
   
   
 
Table of Contents  

designed to protect our proprietary information and, in the case of agreements or clauses requiring invention assignment, to grant us ownership of 
technologies that are developed through a relationship with a third party.  

General considerations  

As with other biotechnology and pharmaceutical companies, our ability to maintain and solidify a proprietary position for ganaxolone 

will depend upon our success in obtaining effective patent claims and enforcing those claims once granted. Our commercial success will depend in 
part upon not infringing upon the proprietary rights of third parties. It is uncertain whether the issuance of any third-party patent would require us 
to alter our development or commercial strategies, obtain licenses, or cease certain activities. The biotechnology and pharmaceutical industries are 
characterized by extensive litigation regarding patents and other intellectual property rights.  

The term of a patent that covers a FDA-approved drug may be eligible for patent term extension, which provides patent term restoration 

as compensation for the patent term lost during the FDA regulatory review process. The Hatch-Waxman Act permits a patent term extension of up 
to five years beyond the expiration of the patent. The length of the patent term extension is related to the length of time the drug is under 
regulatory review. Patent extension cannot extend the remaining term of a patent beyond a total of 14 years from the date of product approval and 
only one patent applicable to an approved drug may be extended. Similar provisions are available in Europe and other foreign jurisdictions to 
extend the term of a patent that covers an approved drug. In the future, if and when our pharmaceutical products receive FDA approval, we expect 
to apply for patent term extensions on patents covering those products.  

Many pharmaceutical companies, biotechnology companies and academic institutions are competing with us in the field of 

neuropsychiatric disorders and filing patent applications potentially relevant to our business. Even when a third-party patent is identified, we may 
conclude upon a thorough analysis, that we do not infringe upon the patent or that the patent is invalid. If the third-party patent owner disagrees 
with our conclusion and we continue with the business activity in question, we may be subject to patent litigation. Alternatively, we might decide 
to initiate litigation in an attempt to have a court declare the third-party patent invalid or non-infringed by our activity. In either scenario, patent 
litigation typically is costly and time-consuming, and the outcome can be favorable or unfavorable.  

Collaborations  

NovaMedica  

In connection with our Series C convertible preferred stock financing, in December 2012, we entered into a Technology Transfer 
Agreement, or the Transfer Agreement, with DRI, a significant stockholder of our company. Pursuant to the Transfer Agreement, in exchange for 
a payment of $100,000, we assigned to DRI certain patents and patents applications in Armenia, Azerbaijan, Belarus, Georgia, Kazakhstan, 
Kyrgyzstan, Moldova, Russia, Tajikistan, Turkmenistan, Ukraine and Uzbekistan, or the Covered Territory, and granted to DRI an exclusive, 
royalty-free, irrevocable and assignable license under our know-how to develop and commercialize ganaxolone and other products that would 
infringe our patent rights or use our know-how, or the Covered Products, in the Covered Territory, in the field of uses for any human or animal 
disease or condition excluding the treatment of unpleasant sensory or emotional experience associated with actual or potential tissue damage or 
described in terms of such damage, or the Field. Immediately thereafter, we, together with DRI, executed an Assignment and Assumption 
Agreement, pursuant to which all of DRI’s rights and obligations under the Transfer Agreement were transferred to NovaMedica, LLC, or 
NovaMedica. We agreed to take all action required to register or record the patent transfers to DRI in each country in the Covered Territory and to 
ensure the assignment of DRI’s rights under the Transfer Agreement to NovaMedica. NovaMedica is jointly owned by Rusnano Medinvest LLC, 
or Rusnano Medinvest, and DRI. RMI Investments, S.á.r.l, a stockholder of ours, is a wholly-owned subsidiary of Rusnano Medinvest.  

Under the terms of the Transfer Agreement, NovaMedica, or its permitted transferees or assignees, has the exclusive right within the 

Covered Territory to manufacture the Covered Products solely for development and commercialization in the Covered Territory in the Field. Until 
the first commercial sale of a Covered Product within the Covered Territory, NovaMedica will have the right to purchase supplies of the Covered 
Product from us as are reasonably available to us and as are reasonable and necessary to conduct clinical trials of Covered Product in the Covered 
Territory, provided that any such purchase does not reasonably interfere with our having sufficient supplies of Covered Products on hand for use 
in development (including the conduct of clinical trials) or commercialization  

12

outside of the Covered Territory. Such purchases will be made on a cost-plus basis. The parties shall enter into the Supply Agreement to supply 
ganaxolone and/or Covered Product for development in the Covered Territory within 60 calendar days from NovaMedica’s request, which we 
have not yet received.  

In accordance with the terms of the Transfer Agreement, on June 25, 2013 we entered into a Clinical Development and Collaboration 

Agreement, or the Collaboration Agreement, with NovaMedica, pursuant to which we agreed to assist NovaMedica in the development and 
commercialization of Covered Products in the Covered Territory in the Field. The Collaboration Agreement requires the formation of committees 
consisting of our representatives and NovaMedica representatives to oversee the general development, day-to-day development work and 
commercialization of Covered Products in the Field in the Covered Territory. All decisions of these committees must be made by unanimous vote, 
subject to a dispute resolution process. Under the terms of the Collaboration Agreement, the joint committees will determine a development plan 
for ganaxolone in clinical trials and a plan for commercialization of ganaxolone. NovaMedica will have sole responsibility for the costs and 
expenses of obtaining regulatory approval for Covered Products and for commercializing any approved products in the Covered Territory, and 
NovaMedica will have the right to conduct its own clinical studies in the Covered Territory at its sole expense. NovaMedica also has the right to 
file applications for approval of Covered Products in the Covered Territory, subject to committee oversight. We have agreed, among other things, 
to provide NovaMedica with data and regulatory files necessary for it to obtain necessary approvals in the Covered Territory, information relating 
to applications for regulatory approval of Covered Products, certain commercialization information and to assist NovaMedica in conducting any 
clinical trials necessary for regulatory approval of Covered Products in the Covered Territory. We also have agreed to provide NovaMedica with 
certain development know-how and support, including making our clinical development personnel available to provide scientific and technical 
explanations, consultation and support that may be reasonably requested by NovaMedica.  

NovaMedica is required to reimburse us for any out-of-pocket expenses incurred by us in providing this assistance, except for expenses 

incurred in our participation on the joint committees. Pursuant to the Collaboration Agreement and the Transfer Agreement, we have agreed to use 
commercially reasonable efforts to include sites in the Russian Federation in our clinical trial programs for the first indications of the Covered 
Products at our sole expense. Under the Transfer Agreement, at least 36 months prior to the first commercial sale of a product candidate in the 
Covered Territory, the parties have agreed to negotiate in good faith a supply agreement pursuant to which we or a third party contract 
manufacturer authorized by us to manufacture and supply the Covered Products, will supply needed quantities of Covered Product to NovaMedica 
solely for commercialization of Covered Products in the Covered Territory, on commercially fair and reasonable terms. Such purchases will be 
made on a cost-plus basis. In the event the parties are unable to agree on pricing under the supply agreement, they have agreed to engage an 
internationally recognized consulting firm reasonably acceptable to both parties to perform an analysis to determine final pricing under the supply 
agreement, which decision will be binding upon the parties. In the event that the parties are unable to reach a reasonably acceptable supply 
agreement or we are unable to supply Covered Products to NovaMedica under such supply agreement for a period of at least 60 calendar days 
after the specified delivery date and we thereafter fail to cure such failure within 60 days after written notice from NovaMedica, we have agreed to 
cooperate with NovaMedica to identify a mutually acceptable alternative source of supply and will provide the necessary consents to allow such 
alternative source of supply to provide the needed quantities of the Covered Products to NovaMedica. The terms of the alternative source of 
supply would be negotiated directly by NovaMedica with the supplier.  

The Collaboration Agreement expires on the earlier of three years following the first commercial sale of a product candidate in the 

Covered Territory and terminates upon the termination of the Transfer Agreement. NovaMedica also has the right to terminate the Collaboration 
Agreement at any time at its convenience upon 90 days’ prior written notice.  

Purdue  

In September 2004, we entered into a license agreement with Purdue, which was most recently amended and restated in May 2008 that 
granted us exclusive rights to certain know-how and technology relating to ganaxolone, excluding the field of treatment of unpleasant sensory or 
emotional experience associated with actual or potential tissue damage, or described in terms of such damage. The agreement contains a right by 
us to sublicense subject to prior written approval by Purdue. We are obligated to pay royalties as a percentage in the range of high single digits up 
to 10% of net product sales for direct licensed products, such as ganaxolone. The obligation to pay royalties expires, on a country-by-country 
basis,  

13  

   
   
   
   
   
   
   
 
Table of Contents  

ten years from the first commercial sale of a licensed product in each country. We believe that we will not be obligated to pay royalties under the 
agreement because the underlying patents have either expired or are not applicable to ganaxolone. In addition, the agreement also requires that we 
pay Purdue a percentage in the mid-single digits of the non-royalty consideration that we receive from a sublicensee and a percentage in the 
twenties of milestone payments for indications other than seizure disorders and vascular migraine headaches not associated with mood disorders. 
Under the license agreement, we are committed to use commercially reasonable efforts to develop and commercialize at least one licensed 
product.  

Competition  

The pharmaceutical industry is highly competitive and subject to rapid and significant technological change. While we believe that our 

development experience and scientific knowledge provide us with competitive advantages, we face competition from both large and small 
pharmaceutical and biotechnology companies, specifically with companies that treat neuropsychiatric disorders.  

There are a variety of available therapies marketed for neuropsychiatric disorders. In many cases, these products are administered in 

combination to enhance efficacy or to reduce side effects. Some of these drugs are branded and subject to patent protection, some are in clinical 
development and not yet approved, and others are available on a generic basis. Many of these approved drugs are well established therapies or 
products and are widely accepted by physicians, patients and third-party payors. Insurers and other third-party payors may also encourage the use 
of generic products. More established companies have a competitive advantage over us due to their greater size, cash flows and institutional 
experience. Compared to us, many of our competitors have significantly greater financial, technical and human resources.  

Our competitors may also develop drugs that are safer, more effective, more widely used and less costly than ours, and may also be more 

successful than us in manufacturing and marketing their products. These appreciable advantages could render ganaxolone obsolete or non-
competitive before we can recover the expenses of ganaxolone’s development and commercialization.  

Mergers and acquisitions in the pharmaceutical and biotechnology industries may result in even more resources being concentrated 

among a smaller number of our competitors. Smaller and other early-stage companies may also prove to be significant competitors, particularly 
through collaborative arrangements with large and established companies. These third parties compete with us in recruiting and retaining qualified 
scientific, management and commercial personnel, establishing clinical trial sites and subject registration for clinical trials, as well as in acquiring 
technologies complementary to, or necessary for, our programs.  

Competitive Landscape  

We primarily compete with pharmaceutical and biotechnology companies that are developing therapies or marketing drugs to treat 

indications that we are targeting.  

Epileptic Seizures  

Currently available AEDs control seizures through a variety of mechanisms, including modulation of voltage-activated sodium channels, 

voltage-activated calcium channels, increasing GABA signaling, and interactions with α 2-δ protein or synaptic vesicle protein SV2A. There are 
more than 15 approved AEDs available in the United States and worldwide. The top prescribed AEDs include the generic products levetiracetam, 
lamotrigine, carbamazepine, oxcarbazepine, valproic acid and topiramate. Decision Resources reports that these AEDs are used to treat a 
substantial percentage of epilepsy patients. Recent market entrants include Vimpat (UCB), Potiga (GlaxoSmithKline) and Fycompa (Eisai), and 
Aptiom (Sunovion Pharmaceuticals). In addition to ganaxolone there are two new chemical entities in late stage development that we are aware 
of, brivaracetam (UCB) and carisbamate (SK Life Science), while Sage Therapeutics is developing SAGE-547, an intravenous formulation of 
allopregnanolone for super-refractory status epilepticus.

Table of Contents  

FXS  

There are no drugs approved for the treatment of behavioral and mental health conditions associated with FXS although various classes 
of medications are used off-label. Some patients with FXS benefit from medications that treat attention deficient disorders and other patients who 
experience general anxiety, social anxiety and other chronic conditions may benefit from different types of anti-anxiety medications.  

We are aware of several drugs in development including a number of generic drugs used for other indications such as donepezil, 

memantine, sertraline, and minocycline. Companies developing compounds include Alcobra, Sunovion Pharmaceuticals, Afraxis and Neuren 
Pharmaceuticals.  

PCDH19-FPE  

There are no drugs approved for the treatment of PCDH19-FPE. PCDH19-FPE patients are typically prescribed drugs approved for 

epileptic seizures, which often times fail to control seizures in this patients population.  

Manufacturing  

Manufacturing of drugs and product candidates, including ganaxolone, must comply with FDA current good manufacturing practice, or 

cGMP, regulations. Ganaxolone is a synthetic small molecule made through a series of organic chemistry steps starting with commercially 
available organic chemical raw materials. We conduct manufacturing activities under individual purchase orders with independent contract 
manufacturing organizations, or CMOs, to supply our clinical trials. We have an internal quality program and have qualified and signed quality 
agreements with our CMOs. We conduct periodic quality audits of their facilities. We believe that our existing suppliers of ganaxolone’s active 
pharmaceutical ingredient and finished product will be capable of providing sufficient quantities of each to meet our clinical trial supply needs. 
Other CMOs may be used in the future for clinical supplies and, subject to approval, commercial manufacturing.  

Ganaxolone Formulations  

The therapeutic possibilities of ganaxolone have been understood for some time, however, because ganaxolone is a high-dose water 

insoluble compound, developing a formulation that could provide consistent drug exposure and could be manufactured at a commercially feasible 
cost had proven challenging. We believe the discovery of our patented nanoparticulate formulation and novel manufacturing process for 
ganaxolone address the pharmacokinetic and cost of manufacturing challenges that previously encumbered the clinical and commercial feasibility 
of ganaxolone.  

Ganaxolone is currently formulated as an oral suspension and as a capsule. We are planning a pharmacokinetic study to establish relative 
potency between the oral suspension to the capsule. Additionally, we have developed an intravenous formulation and a prototype for a tablet. We 
are presently conducting the requisite preclinical experiments to ready our intravenous dose form for clinical use.  

Commercial Operations  

If we obtain FDA approval for ganaxolone as an adjunctive treatment for patients with focal onset seizures we intend to build a sales and 

marketing infrastructure to reach high prescribing neurologist and epilepsy specialists in the United States. We believe a focused sales and 
marketing organization for epilepsy could be leveraged to market ganaxolone in other neurology or psychiatry indications if we are able to obtain 
regulatory approval for those other indications. We may seek co-promotion partners for our sales efforts to reach other United States physician 
groups, such as primary care physicians. We believe that there is significant market opportunity for ganaxolone in epilepsy and other neurological 
and psychiatric conditions outside of the United States. In order to capitalize on this opportunity, we plan to seek collaborations with 
pharmaceutical companies that have greater reach and resources by virtue of their size and experience in the field.  

Government Regulation  

As a clinical stage biopharmaceutical company that operates in the United States, we are subject to extensive regulation by the FDA, and 

other federal, state, and local regulatory agencies. The Federal Food, Drug, and Cosmetic Act, or the FDC Act, and its implementing regulations 
set forth, among other things, requirements for the research, testing, development, manufacture, quality control, safety, effectiveness, approval, 
packaging, labeling, storage, record keeping, reporting, distribution, import, export, advertising and promotion of our products. Although the 
discussion below focuses on regulation in the United States, we anticipate seeking approval for, and marketing of, our products in other countries. 
Generally, our activities in other countries will be subject to regulation that is similar in nature and scope as that imposed in the United States, 
although there can be important differences. Additionally, some significant aspects of regulation in Europe are addressed in a centralized way 
through the EMA,  

15  

   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
 
Table of Contents  

but country-specific regulation remains essential in many respects. The process of obtaining regulatory marketing approvals and the subsequent 
compliance with appropriate federal, state, local and foreign statutes and regulations require the expenditure of substantial time and financial 
resources and may not be successful.  

United States Government Regulation  

The FDA is the main regulatory body that controls pharmaceuticals in the United States, and its regulatory authority is based in the FDC 
Act. Pharmaceutical products are also subject to other federal, state and local statutes. A failure to comply explicitly with any requirements during 
the product development, approval, or post-approval periods, may lead to administrative or judicial sanctions. These sanctions could include the 
imposition by the FDA or an institutional review board, or IRB, of a hold on clinical trials, refusal to approve pending marketing applications or 
supplements, withdrawal of approval, warning letters, product recalls, product seizures, total or partial suspension of production or distribution, 
injunctions, fines, civil penalties or criminal prosecution.  

The steps required before a new drug may be marketed in the United States generally include:  

•                   completion of non-clinical, or preclinical, studies, animal studies and formulation studies in compliance with the FDA’s good 

laboratory practice, or GLP, regulations;  

•                   submission to the FDA of an IND to support human clinical testing;  

•                   approval by an IRB at each clinical site before each trial may be initiated;  

•                   performance of adequate and well-controlled clinical trials in accordance with federal regulations, including requirements for good 
clinical practices, or GCPs, to establish the safety and efficacy of the investigational product candidate for each targeted indication;  

•                   submission of a new drug application, or NDA, to the FDA;  

•                   satisfactory completion of an FDA Advisory Committee review, if applicable;  

•                   satisfactory completion of an FDA inspection of clinical trial sites to ensure compliance with GCPs;  

•                   satisfactory completion of an FDA inspection of the manufacturing facilities at which the investigational product candidate is 

produced to assess compliance with cGMP, and to assure that the facilities, methods and controls are adequate; and  

•                   FDA review and approval of the NDA.  

Clinical Trials  

An IND is a request for authorization from the FDA to administer an investigational product candidate to humans. This authorization is 
required before interstate shipping and administration of any new drug product to humans that is not the subject of an approved NDA. A 30-day 
waiting period after the submission of each IND is required prior to the commencement of clinical testing in humans. If the FDA has neither 
commented on nor questioned the IND within this 30-day period, the clinical trial proposed in the IND may begin. The FDA may submit 
questions after the 30 day period and after the trial was allowed to begin. Clinical trials involve the administration of the investigational product 
candidate to subjects under the supervision of qualified investigators following GCPs, requirements meant to protect the rights and health of 
subjects and to define the roles of clinical trial sponsors, administrators and monitors. Clinical trials are conducted under protocols that detail the 
subject inclusion and exclusion criteria, the dosing regimen, the parameters to be used in monitoring safety, and the efficacy criteria to be 
evaluated. Each protocol involving testing on United States subjects and subsequent protocol amendments must be submitted to the FDA as part 
of the IND. The informed written consent of each participating subject is required. The clinical investigation of an investigational product 
candidate is generally divided into three phases. Although the phases are usually conducted sequentially, they may overlap or be combined. The 
three phases of an investigation are as follows:  

•                   Phase 1.  Phase 1 includes the initial introduction of an investigational product candidate into humans. Phase 1 studies may be 

conducted in subjects with the target disease or condition or healthy volunteers. These studies are designed to evaluate the safety, 
metabolism, pharmacokinetic properties, or PKs, and  

16  

   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
 
Table of Contents  

pharmacologic actions of the investigational product candidate in humans, the side effects associated with increasing doses, and if 
possible, to gain early evidence on effectiveness. During Phase 1 studies, sufficient information about the investigational product 
candidate’s PKs and pharmacological effects may be obtained to permit the design of Phase 2 studies. The total number of 
participants included in Phase 1 studies varies, but is generally in the range of 20 to 80.  

•                   Phase 2.  Phase 2 includes the controlled clinical trials conducted to evaluate the effectiveness of the investigational product 

candidate for a particular indication(s) in subjects with the disease or condition under study, to determine dosage tolerance and 
optimal dosage, and to identify possible adverse side effects and safety risks associated with the product candidate. Phase 2 studies 
are typically well-controlled, closely monitored, and conducted in a limited subject population, usually involving no more than 
several hundred participants.  

•                   Phase 3.  Phase 3 studies are controlled clinical trials conducted in an expanded subject population at geographically dispersed 

clinical trial sites. They are performed after preliminary evidence suggesting effectiveness of the investigational product candidate 
has been obtained, and are intended to further evaluate dosage, clinical effectiveness and safety, to establish the overall benefit-risk 
relationship of the product candidate, and to provide an adequate basis for drug approval. Phase 3 studies usually involve several 
hundred to several thousand participants. In most cases, the FDA requires two adequate and well controlled Phase 3 studies to 
demonstrate the efficacy of the drug. A single Phase 3 study with other confirmatory evidence may be sufficient in rare instances 
where the study is a large multicenter trial demonstrating internal consistency and a statistically very persuasive finding of a 
clinically meaningful effect on mortality, irreversible morbidity or prevention of a disease with a potentially serious outcome and 
confirmation of the result in a second trial would be practically or ethically impossible.  

The decision to terminate development of an investigational product candidate may be made by either a health authority body, such as the 

FDA or IRB/ethics committees, or by a company for various reasons. The FDA may order the temporary, or permanent, discontinuation of a 
clinical trial, which is referred to as a clinical hold, at any time, or impose other sanctions, if it believes that the clinical trial either is not being 
conducted in accordance with FDA requirements or presents an unacceptable risk to the clinical trial subjects. In some cases, clinical trials are 
overseen by an independent group of qualified experts organized by the trial sponsor, or the clinical monitoring board or data safety monitoring 
board. This group provides authorization for whether or not a trial may move forward at designated check points. These decisions are based on the 
limited access to data from the ongoing trial. The suspension or termination of development can occur during any phase of clinical trials if it is 
determined that the participants or subjects are being exposed to an unacceptable health risk. In addition, there are requirements for the 
registration of ongoing clinical trials of product candidates on public registries and the disclosure of certain information pertaining to the trials as 
well as clinical trial results after completion.  

A sponsor may be able to request a special protocol assessment, or SPA, the purpose of which is to reach agreement with the FDA on the 

Phase 3 study protocol design and analysis that will form the primary basis of an efficacy claim. A sponsor meeting the regulatory criteria may 
make a specific request for an SPA and provide information regarding the design and size of the proposed clinical trial. An SPA request must be 
made before the proposed trial begins, and all open issues must be resolved before the trial begins. If a written agreement is reached, it will be 
documented and made part of the record. The agreement will be binding on the FDA and may not be changed by the sponsor or the FDA after the 
trial begins except with the written agreement of the sponsor and the FDA or if the FDA determines that a substantial scientific issue essential to 
determining the safety or efficacy of the product candidate was identified after the testing began. An SPA is not binding if new circumstances 
arise, and there is no guarantee that a study will ultimately be adequate to support an approval even if the study is subject to an SPA.  

Assuming successful completion of all required testing in accordance with all applicable regulatory requirements, detailed investigational 
product candidate information is submitted to the FDA in the form of an NDA to request market approval for the product in specified indications.  

New Drug Applications  

In order to obtain approval to market a drug in the United States, a marketing application must be submitted to the FDA that provides 

data establishing the safety and effectiveness of the product candidate for the proposed indication. The application includes all relevant data 
available from pertinent preclinical studies and clinical trials, including negative or ambiguous results as well as positive findings, together with 
detailed information relating to  

17  

   
   
   
   
   
   
   
   
   
 
Table of Contents  

the product’s chemistry, manufacturing, controls and proposed labeling, among other things. Data can come from company-sponsored clinical 
trials intended to test the safety and effectiveness of a product, or from a number of alternative sources, including studies initiated by investigators. 
To support marketing approval, the data submitted must be sufficient in quality and quantity to establish the safety and effectiveness of the 
investigational product candidate to the satisfaction of the FDA.  

In most cases, the NDA must be accompanied by a substantial user fee; there may be some instances in which the user fee is waived. The 

FDA will initially review the NDA for completeness before it accepts the NDA for filing. The FDA has 60 days from its receipt of an NDA to 
determine whether the application will be accepted for filing based on the agency’s threshold determination that it is sufficiently complete to 
permit substantive review. After the NDA submission is accepted for filing, the FDA begins an in-depth review. The FDA has agreed to certain 
performance goals in the review of NDAs. Most such applications for standard review product candidates are reviewed within ten to twelve 
months. The FDA can extend this review by three months to consider certain late-submitted information or information intended to clarify 
information already provided in the submission. The FDA reviews the NDA to determine, among other things, whether the proposed product is 
safe and effective for its intended use, and whether the product is being manufactured in accordance with cGMP. The FDA may refer applications 
for novel product candidates which present difficult questions of safety or efficacy to an advisory committee, typically a panel that includes 
clinicians and other experts, for review, evaluation and a recommendation as to whether the application should be approved and under what 
conditions. The FDA is not bound by the recommendations of an advisory committee, but it considers such recommendations carefully when 
making decisions.  

Before approving an NDA, the FDA will inspect the facilities at which the product is manufactured. The FDA will not approve the 

product unless it determines that the manufacturing processes and facilities are in compliance with cGMP requirements and adequate to assure 
consistent production of the product within required specifications. Additionally, before approving an NDA, the FDA will typically inspect one or 
more clinical sites to assure compliance with GCP. After the FDA evaluates the NDA and the manufacturing facilities, it issues either an approval 
letter or a complete response letter. A complete response letter generally outlines the deficiencies in the submission and may require substantial 
additional testing or information in order for the FDA to reconsider the application. If, or when, those deficiencies have been addressed to the 
FDA’s satisfaction in a resubmission of the NDA, the FDA will issue an approval letter. The FDA has committed to reviewing such resubmissions 
in two or six months depending on the type of information included. Notwithstanding the submission of any requested additional information, the 
FDA ultimately may decide that the application does not satisfy the regulatory criteria for approval.  

An approval letter authorizes commercial marketing of the drug with specific prescribing information for specific indications. As a 

condition of NDA approval, the FDA may require a risk evaluation and mitigation strategy, or REMS, to help ensure that the benefits of the drug 
outweigh the potential risks. REMS can include medication guides, communication plans for healthcare professionals, and elements to assure safe 
use, or ETASU. ETASU can include, but are not limited to, special training or certification for prescribing or dispensing, dispensing only under 
certain circumstances, special monitoring, and the use of patient registries. The requirement for a REMS can materially affect the potential market 
and profitability of the drug. Moreover, product approval may require substantial post-approval testing and surveillance to monitor the drug’s 
safety or efficacy. Once granted, product approvals may be withdrawn if compliance with regulatory requirements is not maintained or problems 
are identified following initial marketing.  

18  

   
   
   
   
   
 
Table of Contents  

Changes to some of the conditions established in an approved application, including changes in indications, labeling, or manufacturing 

processes or facilities, require submission and FDA approval of a new NDA or NDA supplement before the change can be implemented. An NDA 
supplement for a new indication typically requires clinical data similar to that in the original application, and the FDA uses the same procedures 
and actions in reviewing NDA supplements as it does in reviewing NDAs.  

Advertising and Promotion  

The FDA and other federal regulatory agencies closely regulate the marketing and promotion of drugs through, among other things, 
standards and regulations for direct-to-consumer advertising, communications regarding unapproved uses, industry-sponsored scientific and 
educational activities, and promotional activities involving the Internet. A product cannot be commercially promoted before it is approved. After 
approval, product promotion can include only those claims relating to safety and effectiveness that are consistent with the labeling approved by 
the FDA. Healthcare providers are permitted to prescribe drugs for “off-label” uses—that is, uses not approved by the FDA and therefore not 
described in the drug’s labeling—because the FDA does not regulate the practice of medicine. However, FDA regulations impose stringent 
restrictions on manufacturers’ communications regarding off-label uses. Broadly speaking, a manufacturer may not promote a drug for off-label 
use, but may engage in non-promotional, balanced communication regarding off- label use under specified conditions. Failure to comply with 
applicable FDA requirements and restrictions in this area may subject a company to adverse publicity and enforcement action by the FDA, the 
United States Department of Justice, or DOJ, or the Office of the Inspector General of the United States Department of Health and Human 
Services, or HHS, as well as state authorities. This could subject a company to a range of penalties that could have a significant commercial 
impact, including civil and criminal fines and agreements that materially restrict the manner in which a company promotes or distributes drug 
products.  

Post-Approval Regulations  

After regulatory approval of a drug is obtained, a company is required to comply with a number of post-approval requirements. For 

example, as a condition of approval of an NDA, the FDA may require post-marketing testing, including Phase 4 clinical trials, and surveillance to 
further assess and monitor the product’s safety and effectiveness after commercialization. In addition, as a holder of an approved NDA, a 
company would be required to report adverse reactions and production problems to the FDA, to provide updated safety and efficacy information, 
and to comply with requirements concerning advertising and promotional labeling for any of its products. Also, quality control and manufacturing 
procedures must continue to conform to cGMP after approval to assure and preserve the long term stability of the drug product. The FDA 
periodically inspects manufacturing facilities to assess compliance with cGMP, which imposes extensive procedural and substantive record 
keeping requirements. In addition, changes to the manufacturing process are strictly regulated, and, depending on the significance of the change, 
may require prior FDA approval before being implemented. FDA regulations also require investigation and correction of any deviations from 
cGMP and impose documentation requirements upon a company and any third-party manufacturers that a company may decide to use. 
Accordingly, manufacturers must continue to expend time, money and effort in the area of production and quality control to maintain compliance 
with cGMP and other aspects of regulatory compliance.  

We rely, and expect to continue to rely, on third parties for the production of clinical and commercial quantities of ganaxolone. Future 

FDA and state inspections may identify compliance issues at our facilities or at the facilities of our contract manufacturers that may disrupt 
production or distribution, or require substantial resources to correct. In addition, discovery of previously unknown problems with a product or the 
failure to comply with applicable requirements may result in restrictions on a product, manufacturer or holder of an approved NDA, including 
withdrawal or recall of the product from the market or other voluntary, FDA-initiated or judicial action that could delay or prohibit further 
marketing.  

Newly discovered or developed safety or effectiveness data may require changes to a product’s approved labeling, including the addition 

of new warnings and contraindications, and also may require the implementation of other risk management measures. Also, new government 
requirements, including those resulting from new legislation, may be established, or the FDA’s policies may change, which could delay or prevent 
regulatory approval of our products under development.

The Hatch-Waxman Amendments to the FDC Act  

Orange Book Listing  

In seeking approval for a drug through an NDA, applicants are required to list with the FDA each patent whose claims cover the 

applicant’s product or a method of using the product. Upon approval of a drug, each of the patents listed in the application for the drug is then 
published in the FDA’s Approved Drug Products with Therapeutic Equivalence Evaluations, commonly known as the Orange Book. Drugs listed 
in the Orange Book can, in turn, be cited by potential generic competitors in support of approval of an abbreviated new drug application, or 
ANDA, or 505(b)(2) application. An ANDA provides for marketing of a drug product that has the same active ingredients, generally in the same 
strengths and dosage form, as the listed drug and has been shown through PK testing to be bioequivalent to the listed drug. Other than the 
requirement for bioequivalence testing, ANDA applicants are generally not required to conduct, or submit results of, preclinical studies or clinical 
tests to prove the safety or effectiveness of their drug product. 505(b)(2) applications provide for marketing of a drug product that may have the 
same active ingredients as the listed drug and contains full safety and effectiveness data as an NDA, but at least some of this information comes 
from studies not conducted by or for the applicant. Drugs approved in this way are commonly referred to as “generic equivalents” to the listed 
drug, and can often be substituted by pharmacists under prescriptions written for the original listed drug.  

The ANDA or 505(b)(2) applicant is required to certify to the FDA concerning any patents listed for the approved product in the FDA’s 
Orange Book. Specifically, the applicant must certify that: (i) the required patent information has not been filed; (ii) the listed patent has expired; 
(iii) the listed patent has not expired, but will expire on a particular date and approval is sought after patent expiration; or (iv) the listed patent is 
invalid or will not be infringed by the new product. The ANDA or 505(b)(2) applicant may also elect to submit a statement certifying that its 
proposed ANDA label does not contain (or carves out) any language regarding a patented method of use rather than certify to such listed method 
of use patent. If the applicant does not challenge the listed patents by filing a certification that the listed patent is invalid or will not be infringed 
by the new product, the ANDA or 505(b)(2) application will not be approved until all the listed patents claiming the referenced product have 
expired.  

A certification that the new product will not infringe the already approved product’s listed patents, or that such patents are invalid, is 

called a Paragraph IV certification. If the ANDA or 505(b)(2) applicant has provided a Paragraph IV certification to the FDA, the applicant must 
also send notice of the Paragraph IV certification to the NDA and patent holders once the ANDA or 505(b)(2) application has been accepted for 
filing by the FDA. The NDA and patent holders may then initiate a patent infringement lawsuit in response to the notice of the Paragraph IV 
certification. The filing of a patent infringement lawsuit within 45 days of the receipt of a Paragraph IV certification automatically prevents the 
FDA from approving the ANDA or 505(b)(2) application until the earliest of 30 months, expiration of the patent, settlement of the lawsuit, and a 
decision in the infringement case that is favorable to the ANDA or 505(b)(2) applicant.  

The ANDA or 505(b)(2) application also will not be approved until any applicable non-patent exclusivity listed in the Orange Book for 

the referenced product has expired.  

Marketing Exclusivity  

Upon NDA approval of a new chemical entity, which is a drug that contains no active moiety that has been approved by the FDA in any 

other NDA, that drug receives five years of marketing exclusivity during which the FDA cannot approve any ANDA seeking approval of a 
generic version of that drug. Certain changes to a drug, such as the addition of a new indication to the package insert, are associated with a three-
year period of exclusivity during which the FDA cannot approve an ANDA for a generic drug that includes the change.  

An ANDA may be submitted one year before marketing exclusivity expires if a Paragraph IV certification is filed. In this case, the 

30 months stay, if applicable, runs from the end of the five years marketing exclusivity period. If there is no listed patent in the Orange Book, 
there may not be a Paragraph IV certification, and, thus, no ANDA may be filed before the expiration of the exclusivity period.  

Patent Term Extension  

After NDA approval, owners of relevant drug patents may apply for up to a five year patent extension. The allowable patent term 
extension is calculated as half of the drug’s testing phase—the time between an effective IND and NDA submission—and all of the review 
phase—the time between NDA submission and approval up to a  

20  

   
   
   
   
   
   
   
   
   
   
   
   
 
Table of Contents  

maximum of five years. The time can be shortened if the FDA determines that the applicant did not pursue approval with due diligence. The total 
patent term after the extension may not exceed 14 years.  

Many other countries also provide for patent term extensions or similar extensions of patent protection for pharmaceutical products. For 

example, in Japan, it may be possible to extend the patent term for up to five years and in Europe, it may be possible to obtain a supplementary 
patent certificate that would effectively extend patent protection for up to five years.  

The Foreign Corrupt Practices Act  

The Foreign Corrupt Practices Act, or FCPA, prohibits any United States individual or business from paying, offering, or authorizing 

payment or offering of anything of value, directly or indirectly, to any foreign official, political party or candidate for the purpose of influencing 
any act or decision of the foreign entity in order to assist the individual or business in obtaining or retaining business. The FCPA also obligates 
companies whose securities are listed in the United States to comply with accounting provisions requiring such companies to maintain books and 
records that accurately and fairly reflect all transactions of the corporation, including international subsidiaries, and to devise and maintain an 
adequate system of internal accounting controls for international operations.  

European and Other International Government Regulation  

In addition to regulations in the United States, we will be subject to a variety of regulations in other jurisdictions governing, among other 

things, clinical trials and any commercial sales and distribution of our products. Whether or not we obtain FDA approval for a product, we must 
obtain the requisite approvals from regulatory authorities in foreign countries prior to the commencement of clinical trials or marketing of the 
product in those countries. Some countries outside of the United States have a similar process that requires the submission of a request for a 
clinical trial authorization, or CTA, much like the IND prior to the commencement of human clinical trials. In Europe, for example, a request for a 
CTA must be submitted to each country’s national health authority and an independent ethics committee, much like the FDA and IRB, 
respectively. Once the CTA request is approved in accordance with a country’s requirements, clinical trial development may proceed.  

To obtain regulatory approval to commercialize a new drug under European Union regulatory systems, we must submit a marketing 

authorization application, or MAA. The MAA is similar to the NDA, with the exception of, among other things, country-specific document 
requirements.  

For other countries outside of the European Union, such as countries in Eastern Europe, Russia, Latin America or Asia, the requirements 
governing the conduct of clinical trials, product licensing, pricing and reimbursement vary from country to country. Internationally, clinical trials 
are generally required to be conducted in accordance with GCP, applicable regulatory requirements of each jurisdiction and the medical ethics 
principles that have their origin in the Declaration of Helsinki.  

Compliance  

During all phases of development (pre- and post-marketing), failure to comply with applicable regulatory requirements may result in 

administrative or judicial sanctions. These sanctions could include the FDA’s imposition of a clinical hold on trials, refusal to approve pending 
applications, withdrawal of an approval, warning letters, product recalls, product seizures, total or partial suspension of production or distribution, 
product detention or refusal to permit the import or export of products, injunctions, fines, civil penalties or criminal prosecution. Any agency or 
judicial enforcement action could have a material adverse effect on us.  

Other Special Regulatory Procedures  

Orphan Drug Designation  

The FDA may grant Orphan Drug Designation to drugs intended to treat a rare disease or condition that affects fewer than 200,000 

individuals in the United States, or, if the disease or condition affects more than 200,000 individuals in the United States, there is no reasonable 
expectation that the cost of developing and making the drug would be recovered from sales in the United States. In the European Union, the 
EMA’s Committee for Orphan Medicinal Products grants Orphan Drug Designation to promote the development of products that are intended for 
the diagnosis, prevention or treatment of life-threatening or chronically debilitating conditions affecting not more  

21  

   
   
   
   
   
   
   
   
   
   
   
   
   
   
 
Table of Contents  

than five in 10,000 persons in the European Union community. Additionally, designation is granted for products intended for the diagnosis, 
prevention or treatment of a life- threatening, seriously debilitating or serious and chronic condition and when, without incentives, it is unlikely 
that sales of the drug in the European Union would be sufficient to justify the necessary investment in developing the drug.  

In the United States, Orphan Drug Designation entitles a party to financial incentives, such as opportunities for grant funding towards 

clinical trial costs, tax credits for certain research and user fee waivers under certain circumstances. In addition, if a product receives the first FDA 
approval for the indication for which it has orphan designation, the product is entitled to seven years of market exclusivity, which means the FDA 
may not approve any other application for the same drug for the same indication for a period of seven years, except in limited circumstances, such 
as a showing of clinical superiority over the product with orphan exclusivity. Orphan drug exclusivity does not prevent the FDA from approving a 
different drug for the same disease or condition, or the same drug for a different disease or condition.  

In the European Union, Orphan Drug Designation also entitles a party to financial incentives such as reduction of fees or fee waivers and 

ten years of market exclusivity is granted following drug approval. This period may be reduced to six years if the Orphan Drug Designation 
criteria are no longer met, including where it is shown that the product is sufficiently profitable not to justify maintenance of market exclusivity.  

Orphan drug designation must be requested before submission of an application for marketing approval. Orphan drug designation does 

not convey any advantage in, or shorten the duration of the regulatory review and approval process.  

Priority Review (United States) and Accelerated Review (European Union)  

Based on results of the Phase 3 study(ies) submitted in an NDA, upon the request of an applicant, a priority review designation may be 
granted to a product by the FDA, which sets the target date for FDA action on the application at six months from FDA filing. Priority review is 
given where preliminary estimates indicate that a product, if approved, has the potential to provide a safe and effective therapy where no 
satisfactory alternative therapy exists, or a significant improvement compared to marketed products is possible. If criteria are not met for priority 
review, the standard FDA review period is ten months from FDA filing. Priority review designation does not change the scientific/medical 
standard for approval or the quality of evidence necessary to support approval.  

Under the Centralized Procedure in the European Union, the maximum timeframe for the evaluation of a MAA is 210 days (excluding 

“clock stops,” when additional written or oral information is to be provided by the applicant in response to questions asked by the Committee for 
Medicinal Products for Human Use, or CHMP). Accelerated evaluation might be granted by the CHMP in exceptional cases, when a medicinal 
product is expected to be of a major public health interest, defined by three cumulative criteria: the seriousness of the disease (e.g., heavy 
disabling or life-threatening diseases) to be treated; the absence or insufficiency of an appropriate alternative therapeutic approach; and 
anticipation of high therapeutic benefit. In this circumstance, EMA ensures that the opinion of the CHMP is given within 150 days.  

Healthcare Reform  

In March 2010, President Obama signed one of the most significant healthcare reform measures in decades. The Patient Protection and 

Affordable Care Act and the Health Care and Education Reconciliation Act of 2010, or Affordable Care Act, substantially changes the way 
healthcare will be financed by both governmental and private insurers, and significantly impacts the pharmaceutical industry. The Affordable Care 
Act will impact existing government healthcare programs and will result in the development of new programs. For example, the Affordable Care 
Act provides for Medicare payment for performance initiatives and improvements to the physician quality reporting system and feedback 
program.  

Among the Affordable Care Act’s provisions of importance to the pharmaceutical industry are the following:  

•                   an annual, nondeductible fee on any covered entity engaged in manufacturing or importing certain branded prescription drugs and 
biological products, apportioned among such entities in accordance with their respective market share in certain government 
healthcare programs;  

22  

   
   
   
   
   
   
   
   
   
   
   
   
 
Table of Contents  

•                   an increase in the statutory minimum rebates a manufacturer must pay under the Medicaid Drug Rebate Program, retroactive to 

January 1, 2010, to 23.0% and 13.0% of the average manufacturer price, or AMP, for most branded and generic drugs, respectively;  

•                   expansion of healthcare fraud and abuse laws, including the False Claims Act and the Anti-Kickback Statute, new government 

investigative powers, and enhanced penalties for noncompliance;  

•                   a new partial prescription drug benefit for Medicare recipients, or Medicare Part D, coverage gap discount program, in which 
manufacturers must agree to offer 50.0% point-of-sale discounts off negotiated prices of applicable brand drugs to eligible 
beneficiaries during their coverage gap period, as a condition for the manufacturers’ outpatient drugs to be covered under Medicare 
Part D;  

•                   extension of manufacturers’ Medicaid rebate liability to covered drugs dispensed to individuals who are enrolled in Medicaid 

managed care organizations;  

•                   expansion of eligibility criteria for Medicaid programs by, among other things, allowing states to offer Medicaid coverage to 

additional individuals beginning in 2014 and by adding new mandatory eligibility categories for individuals with income at or below 
133.0% of the Federal Poverty Level, thereby potentially increasing manufacturers’ Medicaid rebate liability;  

•                   expansion of the entities eligible for discounts under the Public Health Service pharmaceutical pricing program;  

•                   new requirements to report annually specified financial arrangements with physicians and teaching hospitals, as defined in the 

Affordable Care Act and its implementing regulations, including reporting any “payments or transfers of value” made or distributed 
to physicians and teaching hospitals,and reporting any ownership and investment interests held by physicians and their immediate 
family members and applicable group purchasing organizations during the preceding calendar year, with data collection to be 
required beginning August 1, 2013 and reporting to the Centers for Medicare and Medicaid Services, or CMS, to be required by 
March 31, 2014 and by the 90th day of each subsequent calendar year;  

•                   a new requirement to annually report drug samples that manufacturers and distributors provide to physicians;  

•                   a new Patient-Centered Outcomes Research Institute to oversee, identify priorities in, and conduct comparative clinical 

effectiveness research, along with funding for such research; and  

•                   a mandatory nondeductible payment for employers with 50 or more full-time employees (or equivalents) who fail to provide certain 
minimum health insurance coverage for such employees and their dependents, beginning in 2015 (pursuant to relief enacted by the 
Treasury Department).  

The Affordable Care Act also establishes an Independent Payment Advisory Board, or IPAB, to reduce the per capita rate of growth in 

Medicare spending. Beginning in 2014, IPAB is mandated to propose changes in Medicare payments if it determines that the rate of growth of 
Medicare expenditures exceeds target growth rates. The IPAB has broad discretion to propose policies to reduce expenditures, which may have a 
negative impact on payment rates for pharmaceutical products. A proposal made by the IPAB is required to be implemented by CMS unless 
Congress adopts a proposal with savings greater than those proposed by the IPAB. IPAB proposals may impact payments for physician and free-
standing services beginning in 2015 and for hospital services beginning in 2020.  

In addition, other legislative changes have been proposed and adopted since the Affordable Care Act was enacted. In August 2011, 
President Obama signed into law the Budget Control Act of 2011, which, among other things, created the Joint Select Committee on Deficit 
Reduction to recommend proposals in spending reductions to Congress. The Joint Select Committee did not achieve its targeted deficit reduction 
of an amount greater than $1.2 trillion for the years 2013 through 2021, triggering the legislation’s automatic reductions to several government 
programs. These reductions include aggregate reductions to Medicare payments to healthcare providers of up to 2.0% per fiscal year, starting in 
2013. In January 2013, President Obama signed into law the American Taxpayer Relief Act of 2012, which, among other things, reduced 
Medicare payments to several categories of healthcare providers and increased the statute of limitations period for the government to recover 
overpayments to providers  

23

from three to five years. These new laws may result in additional reductions in Medicare and other healthcare funding, which could have a 
material adverse effect on our customers and accordingly, our financial operations.  

We anticipate that the Affordable Care Act will result in additional downward pressure on coverage and the price that we receive for any 

approved product, and could seriously harm our business. Any reduction in reimbursement from Medicare and other government programs may 
result in a similar reduction in payments from private payors. The implementation of cost containment measures or other healthcare reforms may 
prevent us from being able to generate revenue, attain profitability, or commercialize our products. In addition, it is possible that there will be 
further legislation or regulation that could harm our business, financial condition and results of operations.  

Coverage and Reimbursement  

Significant uncertainty exists as to the coverage and reimbursement status of any drug products for which we obtain regulatory approval. 

In the United States and markets in other countries, sales of any products for which we receive regulatory approval for commercial sale will 
depend in part on the availability of reimbursement from third-party payors. Third-party payors include government health administrative 
authorities, managed care providers, private health insurers and other organizations. The process for determining whether a payor will provide 
coverage for a drug product may be separate from the process for setting the price or reimbursement rate that the payor will pay for the drug 
product. Third-party payors may limit coverage to specific drug products on an approved list, or formulary, which might not include all of the 
FDA-approved drugs for a particular indication. Third-party payors are increasingly challenging the price and examining the medical necessity 
and cost- effectiveness of medical products and services, in addition to their safety and efficacy. We may need to conduct expensive 
pharmacoeconomic studies in order to demonstrate the medical necessity and cost-effectiveness of our products, in addition to the costs required 
to obtain FDA approvals. Ganaxolone may not be considered medically necessary or cost-effective. A payor’s decision to provide coverage for a 
drug product does not imply that an adequate reimbursement rate will be approved. Adequate third-party reimbursement may not be available to 
enable us to maintain price levels sufficient to realize an appropriate return on our investment in product development.  

In 2003, the United States Congress enacted legislation providing Medicare Part D, which became effective at the beginning of 2006. 

Government payment for some of the costs of prescription drugs may increase demand for any products for which we receive marketing approval. 
However, to obtain payments under this program, we would be required to sell products to Medicare recipients through prescription drug plans 
operating pursuant to this legislation. These plans will likely negotiate discounted prices for our products. Federal, state and local governments in 
the United States continue to consider legislation to limit the growth of healthcare costs, including the cost of prescription drugs. Future legislation 
could limit payments for pharmaceuticals such as the product candidates that we are developing.  

Different pricing and reimbursement schemes exist in other countries. In the European Union, governments influence the price of 
pharmaceutical products through their pricing and reimbursement rules and control of national healthcare systems that fund a large part of the cost 
of those products to consumers. Some jurisdictions operate positive and negative list systems under which products may only be marketed once a 
reimbursement price has been agreed upon. To obtain reimbursement or pricing approval, some of these countries may require the completion of 
clinical trials that compare the cost-effectiveness of a particular product candidate to currently available therapies. Other member states allow 
companies to fix their own prices for medicines, but monitor and control company profits. The downward pressure on healthcare costs in general, 
particularly prescription drugs, has become more intense. As a result, increasingly high barriers are being erected to the entry of new products. 
The European Union provides options for its member states to restrict the range of medicinal products for which their national health insurance 
systems provide reimbursement and to control the prices of medicinal products for human use. A member state may approve a specific price for 
the medicinal product or it may instead adopt a system of direct or indirect controls on the profitability of the company placing the medicinal 
product on the market. We may face competition for ganaxolone from lower-priced products in foreign countries that have placed price controls 
on pharmaceutical products. In addition, in some countries, cross-border imports from low-priced markets exert a commercial pressure on pricing 
within a country.  

The marketability of any products for which we receive regulatory approval for commercial sale may suffer if the government and third-
party payors fail to provide adequate coverage and reimbursement. In addition, an increasing emphasis on managed care in the United States has 
increased and will continue to increase the pressure on pharmaceutical pricing. Coverage policies and third-party reimbursement rates may change 
at any time.  

24  

   
   
   
   
   
   
   
   
 
Table of Contents  

Even if favorable coverage and reimbursement status is attained for one or more products for which we receive regulatory approval, less 

favorable coverage policies and reimbursement rates may be implemented in the future.  

Other Healthcare Laws and Compliance Requirements  

The federal Anti-Kickback Statute prohibits, among other things, knowingly and willfully offering, paying, soliciting or receiving 
remuneration to induce or in return for purchasing, leasing, ordering or arranging for the purchase, lease or order of any healthcare item or service 
reimbursable under Medicare, Medicaid or other federally financed healthcare programs. This statute has been interpreted to apply to 
arrangements between pharmaceutical manufacturers on one hand and prescribers, purchasers, and formulary managers on the other. Although 
there are a number of statutory exemptions and regulatory safe harbors protecting some business arrangements from prosecution, the exemptions 
and safe harbors are drawn narrowly and practices that involve remuneration intended to induce prescribing, purchasing or recommending may be 
subject to scrutiny if they do not qualify for an exemption or safe harbor. Our practices may not in all cases meet all of the criteria for safe harbor 
protection from federal Anti-Kickback Statute liability. The reach of the Anti-Kickback Statute was broadened by the Affordable Care Act, which, 
among other things, amends the intent requirement of the federal Anti-Kickback Statute. Pursuant to the statutory amendment, a person or entity 
no longer needs to have actual knowledge of this statute or specific intent to violate it in order to have committed a violation. In addition, the 
Affordable Care Act provides that the government may assert that a claim including items or services resulting from a violation of the federal 
Anti-Kickback Statute constitutes a false or fraudulent claim for purposes of the civil False Claims Act (discussed below) or the civil monetary 
penalties statute, which imposes penalties against any person who is determined to have presented or caused to be presented a claim to a federal 
health program that the person knows or should know is for an item or service that was not provided as claimed or is false or fraudulent.  

The federal False Claims Act prohibits any person from knowingly presenting, or causing to be presented, a false claim for payment to 

the federal government or knowingly making, using, or causing to be made or used a false record or statement material to a false or fraudulent 
claim to the federal government. As a result of a modification made by the Fraud Enforcement and Recovery Act of 2009, a claim includes “any 
request or demand” for money or property presented to the United States government. Recently, several pharmaceutical and other healthcare 
companies have been prosecuted under these laws for allegedly providing free product to customers with the expectation that the customers would 
bill federal programs for the product. Other companies have been prosecuted for causing false claims to be submitted because of the companies’ 
marketing of the product for unapproved, and thus non-reimbursable, uses. The Health Insurance Portability and Accountability Act of 1996, or 
HIPAA, created new federal criminal statutes that prohibit knowingly and willfully executing a scheme to defraud any healthcare benefit program, 
including private third-party payors and knowingly and willfully falsifying, concealing or covering up a material fact or making any materially 
false, fictitious or fraudulent statement in connection with the delivery of or payment for healthcare benefits, items or services. Also, many states 
have similar fraud and abuse statutes or regulations that apply to items and services reimbursed under Medicaid and other state programs, or, in 
several states, apply regardless of the payor.  

In addition, we may be subject to data privacy and security regulation by both the federal government and the states in which we conduct 

our business. HIPAA, as amended by The Health Information Technology for Economic and Clinical Health Act, or HITECH, and its 
implementing regulations, imposes requirements relating to the privacy, security and transmission of individually identifiable health information. 
Among other things, HITECH makes HIPAA’s privacy and security standards directly applicable to “business associates”—independent 
contractors or agents of covered entities that receive or obtain protected health information in connection with providing a service on behalf of a 
covered entity. HITECH also increased the civil and criminal penalties that may be imposed against covered entities, business associates and 
possibly other persons, and gave state attorneys general new authority to file civil actions for damages or injunctions in federal courts to enforce 
the federal HIPAA laws and seek attorney’s fees and costs associated with pursuing federal civil actions. In addition, state laws govern the privacy 
and security of health information in specified circumstances, many of which differ from each other in significant ways and may not have the 
same effect, thus complicating compliance efforts.  

In the United States our activities are potentially subject to additional regulation by various federal, state and local authorities in addition 

to the FDA, including CMS, other divisions of HHS (for example, the Office of Inspector General), the DOJ and individual United States 
Attorney offices within the DOJ, and state and local governments. If a drug product is reimbursed by Medicare or Medicaid, pricing and rebate 
programs must comply with, as applicable, The Medicare Prescription Drug, Improvement, and Modernization Act of 2003, or Medicare 
Modernization Act, as well as the Medicaid rebate requirements of the Omnibus Budget Reconciliation Act of 1990,  

25  

   
   
   
   
   
   
   
 
Table of Contents  

or the OBRA, and the Veterans Health Care Act of 1992, or the VHCA, each as amended. Among other things, the OBRA requires drug 
manufacturers to pay rebates on prescription drugs to state Medicaid programs and empowers states to negotiate rebates on pharmaceutical prices, 
which may result in prices for our future products that will likely be lower than the prices we might otherwise obtain. If products are made 
available to authorized users of the Federal Supply Schedule of the General Services Administration, additional laws and requirements apply. 
Under the VHCA, drug companies are required to offer some drugs at a reduced price to a number of federal agencies including the United States 
Department of Veterans Affairs and the DoD, the Public Health Service and some private Public Health Service designated entities in order to 
participate in other federal funding programs including Medicaid. Recent legislative changes require that discounted prices be offered for 
specified DoD purchases for its TRICARE program via a rebate system. Participation under the VHCA requires submission of pricing data and 
calculation of discounts and rebates pursuant to complex statutory formulas, as well as the entry into government procurement contracts governed 
by the Federal Acquisition Regulation.  

Because of the breadth of these laws and the narrowness of available statutory and regulatory exemptions, it is possible that some of our 

business activities could be subject to challenge under one or more of such laws. If our operations are found to be in violation of any of the federal 
and state laws described above or any other governmental regulations that apply to us, we may be subject to penalties, including criminal and 
significant civil monetary penalties, damages, fines, imprisonment, exclusion from participation in government programs, injunctions, recall or 
seizure of products, total or partial suspension of production, denial or withdrawal of pre-marketing product approvals, private “qui tam” actions 
brought by individual whistleblowers in the name of the government or refusal to allow us to enter into supply contracts, including government 
contracts, and the curtailment or restructuring of our operations, any of which could adversely affect our ability to operate our business and our 
results of operations. To the extent that any of our products are sold in a foreign country, we may be subject to similar foreign laws and 
regulations, which may include, for instance, applicable post- marketing requirements, including safety surveillance, anti-fraud and abuse laws, 
and implementation of corporate compliance programs and reporting of payments or transfers of value to healthcare professionals.  

In order to distribute products commercially, we must comply with state laws that require the registration of manufacturers and wholesale 
distributors of pharmaceutical products in a state, including, in some states, manufacturers and distributors who ship products into the state even if 
such manufacturers or distributors have no place of business within the state. Some states also impose requirements on manufacturers and 
distributors to establish the pedigree of product in the chain of distribution, including some states that require manufacturers and others to adopt 
new technology capable of tracking and tracing product as it moves through the distribution chain. In addition, in November 2013, the Drug 
Quality and Security Act became law and establishes requirements to facilitate the tracing of prescription drug products through the 
pharmaceutical supply distribution chain. This law includes a number of new requirements that will be implemented over time and will require us 
to devote additional resources to satisfy these requirements. Several states have enacted legislation requiring pharmaceutical companies to, among 
other things, establish marketing compliance programs, file periodic reports with the state, make periodic public disclosures on sales, marketing, 
pricing, clinical trials and other activities, and/or register their sales representatives, as well as to prohibit pharmacies and other healthcare entities 
from providing specified physician prescribing data to pharmaceutical companies for use in sales and marketing, and to prohibit other specified 
sales and marketing practices. All of our activities are potentially subject to federal and state consumer protection and unfair competition laws.  

Research and Development  

Conducting research and development is central to our business model. We have invested and expect to continue to invest significant 

time and capital in our research and development operations. Our research and development expenses were $8.7 million and $4.2 million in 2014 
and 2013, respectively.  

Employees  

As of December 31, 2014, we had nine full-time employees. In addition to our full-time employees, we contract with third-parties for the 

conduct of certain clinical development, manufacturing, accounting and administrative activities. We anticipate increasing our head count. We 
have no collective bargaining agreements with our employees and none are represented by labor unions.

Item 1A. Risk Factors.  

Risks Related to Our Financial Position and Capital Needs  

We have a limited operating history, have incurred significant losses since our inception and anticipate that we will continue to incur losses in 
the future.  

We commenced operations in 2003, and we have only a limited operating history upon which you can evaluate our business and 

prospects. Our operations to date have been limited to conducting product development activities for ganaxolone and performing research and 
development with respect to our clinical and preclinical programs. In addition, as a clinical stage biopharmaceutical company, we have not yet 
demonstrated an ability to successfully overcome many of the risks and uncertainties frequently encountered by companies in new and rapidly 
evolving fields, particularly in the biopharmaceutical area. Nor have we demonstrated an ability to obtain regulatory approval for or to 
commercialize any of our product candidates. Consequently, any predictions about our future performance may not be as accurate as they would 
be if we had a history of successfully developing and commercializing biopharmaceutical products.  

We have incurred significant operating losses since our inception, including net losses of $10.8 million for the year ended December 31, 

2014. As of December 31, 2014, we had an accumulated deficit of $72.3 million. Our prior losses, combined with expected future losses, have had 
and will continue to have an adverse effect on our stockholders’ equity and working capital. Our losses have resulted principally from costs 
incurred in our research and development activities. We anticipate that our operating losses will substantially increase over the next several years 
as we execute our plan to expand our research, development and commercialization activities, including the clinical development and planned 
commercialization of our product candidate, ganaxolone, and incur the additional costs of operating as a public company. In addition, if we obtain 
regulatory approval of ganaxolone, we may incur significant sales and marketing expenses. Because of the numerous risks and uncertainties 
associated with developing biopharmaceutical products, we are unable to predict the extent of any future losses or whether or when we will 
become profitable, if ever.  

We have not generated any revenue to date from product sales. We may never achieve or sustain profitability, which could depress the market 
price of our common stock, and could cause you to lose all or a part of your investment.  

To date, we have no products approved for commercial sale and have not generated any revenue from sales of any of our product 

candidates, and we do not know when, or if, we will generate revenues in the future. Our ability to generate revenue from product sales and 
achieve profitability will depend upon our ability to successfully gain regulatory approval and commercialize ganaxolone or other product 
candidates that we may develop, in-license or acquire in the future. Even if we are able to successfully achieve regulatory approval for 
ganaxolone, we do not know when we will generate revenue from product sales, if at all. Our ability to generate revenue from product sales from 
ganaxolone or any other future product candidates also depends on a number of additional factors, including our ability to:  

•                   successfully complete development activities, including enrollment of study participants and completion of the necessary clinical 

trials;  

•                   complete and submit new drug applications, or NDAs, to the United States Food and Drug Administration, or FDA, and obtain 

regulatory approval for indications for which there is a commercial market;  

•                   complete and submit applications to, and obtain regulatory approval from, foreign regulatory authorities;  

•                   make or have made commercial quantities of our products at acceptable cost levels;

Table of Contents  

•                   develop a commercial organization capable of manufacturing, selling, marketing and distributing any products we intend to sell 

ourselves in the markets in which we choose to commercialize on our own;  

•                   find suitable partners to help us market, sell and distribute our approved products in other markets; and  

•                   obtain adequate pricing, coverage and reimbursement from third parties, including government and private payors.  

In addition, because of the numerous risks and uncertainties associated with product development, including that ganaxolone may not 
advance through development or achieve the endpoints of applicable clinical trials, we are unable to predict the timing or amount of increased 
expenses, or if or when we will be able to achieve or maintain profitability. Even if we are able to complete the development and regulatory 
process for ganaxolone, we anticipate incurring significant costs associated with commercializing ganaxolone.  

Even if we are able to generate revenue from the sale of ganaxolone or any future commercial products, we may not become profitable 

and will need to obtain additional funding to continue operations. If we fail to become profitable or are unable to sustain profitability on a 
continuing basis, and we are not successful in obtaining additional funding, then we may be unable to continue our operations at planned levels, 
which would depress the market price of our common stock.  

We will require additional capital to fund our operations and if we fail to obtain necessary financing, we may be unable to complete the 
development and commercialization of ganaxolone.  

Our operations have consumed substantial amounts of cash since inception. We expect to continue to spend substantial amounts to 

advance the clinical development of ganaxolone and launch and commercialize ganaxolone, if we receive regulatory approval. We will require 
additional capital for the further development and potential commercialization of ganaxolone and may also need to raise additional funds sooner to 
pursue a more accelerated development of ganaxolone. If we are unable to raise capital when needed or on attractive terms, we could be forced to 
delay, reduce or eliminate our research and development programs or any future commercialization efforts.  

We believe that our cash and cash equivalents as of December 31, 2014, will enable us to fund our operating expenses and capital 

expenditure requirements into the second half of 2016. We have based this estimate on assumptions that may prove to be wrong, and we could 
deploy our available capital resources sooner than we currently expect. Our future funding requirements, both near and long-term, will depend on 
many factors, including, but not limited to the:  

•                   initiation, progress, timing, costs and results of preclinical studies and clinical trials, including patient enrollment in such trials, for 

ganaxolone or any other future product candidates;  

•                   clinical development plans we establish for ganaxolone and any other future product candidates;  

•                   obligation to make royalty and non-royalty sublicense receipt payments to third-party licensors, if any, under our licensing 

agreements;  

•                   number and characteristics of product candidates that we discover or in-license and develop;  

•                   outcome, timing and cost of regulatory review by the FDA and comparable foreign regulatory authorities, including the potential for 
the FDA or comparable foreign regulatory authorities to require that we perform more studies than those that we currently expect;  

•                   costs of filing, prosecuting, defending and enforcing any patent claims and maintaining and enforcing other intellectual property 

rights;  

•                   effects of competing technological and market developments;  

•                   costs and timing of the implementation of commercial-scale manufacturing activities; and  

•                   costs and timing of establishing sales, marketing and distribution capabilities for any product candidates for which we may receive 

regulatory approval.

If we are unable to expand our operations or otherwise capitalize on our business opportunities due to a lack of capital, our ability to 

become profitable will be compromised.  

Raising additional capital may cause dilution to our stockholders, restrict our operations or require us to relinquish rights to ganaxolone or 
any other future product candidates.  

Until we can generate substantial revenue from product sales, if ever, we expect to seek additional capital through a combination of 

private and public equity offerings, debt financings, strategic collaborations and alliances and licensing arrangements. To the extent that we raise 
additional capital through the sale of equity or convertible debt securities, the ownership interests of stockholders will be diluted, and the terms 
may include liquidation or other preferences that adversely affect the rights of stockholders. Debt financing, if available, may involve agreements 
that include liens or other restrictive covenants limiting our ability to take important actions, such as incurring additional debt, making capital 
expenditures or declaring dividends. If we raise additional funds through strategic collaborations and alliances or licensing arrangements with 
third parties, we may have to relinquish valuable rights to ganaxolone or any other future product candidates in particular countries, or grant 
licenses on terms that are not favorable to us. If we are unable to raise additional funds through equity or debt financing when needed, we may be 
required to delay, limit, reduce or terminate our product development or commercialization efforts or grant rights to develop and market 
ganaxolone or any other future product candidates that we would otherwise prefer to develop and market ourselves.  

We intend to expend our limited resources to pursue our sole clinical stage product candidate, ganaxolone, for seizure disorders and may fail 
to capitalize on other indications, technologies or product candidates that may be more profitable or for which there may be a greater 
likelihood of success.  

Because we have limited financial and managerial resources, we are focusing on research programs relating to ganaxolone for focal onset 

seizures, which concentrates the risk of product failure in the event ganaxolone proves to be ineffective or inadequate for clinical development or 
commercialization in this indication. As a result, we may forego or delay pursuit of opportunities for other indications or with other technologies 
or product candidates that later could prove to have greater commercial potential. We may be unable to capitalize on viable commercial products 
or profitable market opportunities as a result of our resource allocation decisions. Our spending on proprietary research and development 
programs relating to ganaxolone may not yield any commercially viable products. If we do not accurately evaluate the commercial potential or 
target market for ganaxolone, we may relinquish valuable rights to ganaxolone through collaboration, licensing or other royalty arrangements in 
cases in which it would have been more advantageous for us to retain sole development and commercialization rights to ganaxolone.  

Risks Related to Our Business and Development of Our Product  

Our future success is dependent on the successful clinical development, regulatory approval and commercialization of ganaxolone, which is 
currently undergoing two clinical trials and will require significant capital resources and years of additional clinical development effort.  

We do not have any products that have gained regulatory approval. Currently, our only clinical stage product candidate is ganaxolone. As 

a result, our business is dependent on our ability to successfully complete clinical development of, obtain regulatory approval for, and, if 
approved, successfully commercialize ganaxolone in a timely manner. We cannot commercialize ganaxolone in the United States without first 
obtaining regulatory approval from the FDA; similarly, we cannot commercialize ganaxolone outside of the United States without obtaining 
regulatory approval from comparable foreign regulatory authorities. Before obtaining regulatory approvals for the commercial sale of ganaxolone 
for a target indication, we must demonstrate with substantial evidence gathered in preclinical studies and clinical trials, generally including two 
adequate and well-controlled clinical trials, and, with respect to approval in the United States, to the satisfaction of the FDA, that ganaxolone is 
safe and effective for use for that target indication and that the manufacturing facilities, processes and controls are adequate. We have expanded 
our ongoing Phase 2b clinical trial so that it may serve as one of our adequate and well-controlled clinical trials for ganaxolone in epilepsy; 
however, we cannot be certain that the FDA will accept the trial as such. Even if ganaxolone were to successfully obtain approval from the FDA 
and comparable foreign regulatory authorities, any approval might contain significant limitations related to use restrictions for specified age 
groups, warnings, precautions or contraindications, or may be subject to burdensome post-approval study or risk management requirements. If we 
are unable to obtain regulatory approval for ganaxolone in one or more jurisdictions, or any approval contains significant limitations, we may not 
be able to obtain sufficient funding or generate sufficient revenue to continue the development of any other product candidate that we may in-
license,  

29  

   
   
   
   
   
   
   
   
   
 
Table of Contents  

develop or acquire in the future. Furthermore, even if we obtain regulatory approval for ganaxolone, we will still need to develop a commercial 
organization, establish commercially viable pricing and obtain approval for adequate reimbursement from third-party and government payors. If 
we are unable to successfully commercialize ganaxolone, we may not be able to earn sufficient revenue to continue our business.  

Because the results of preclinical studies or earlier clinical trials are not necessarily predictive of future results, ganaxolone may not have 
favorable results in later preclinical studies or clinical trials or receive regulatory approval.  

Success in preclinical studies and early clinical trials does not ensure that later trials will generate adequate data to demonstrate the 
efficacy and safety of ganaxolone. A number of companies in the pharmaceutical and biotechnology industries, including those with greater 
resources and experience, have suffered significant setbacks in preclinical studies and clinical trials, even after seeing promising results in earlier 
studies and trials. Despite the results reported in earlier clinical trials for ganaxolone, we do not know whether the clinical trials we may conduct 
will demonstrate adequate efficacy and safety to result in regulatory approval to market ganaxolone in any particular jurisdiction. If later stage 
clinical trials do not produce favorable results, our ability to achieve regulatory approval for ganaxolone may be adversely impacted.  

The therapeutic efficacy and safety of ganaxolone are unproven, and we may not be able to successfully develop and commercialize 
ganaxolone in the future.  

Ganaxolone is a novel compound and its potential benefit as a therapeutic for focal onset seizures, PCDH19 female pediatric epilepsy, or 
PCDH19, and Fragile X Syndrome, or FXS, is unproven. Our ability to generate revenue from ganaxolone, which we do not expect will occur for 
at least the next several years, if ever, will depend heavily on our successful development and commercialization after regulatory approval, which 
is subject to many potential risks and may not occur. Ganaxolone may interact with human biological systems in unforeseen, ineffective or 
harmful ways. If ganaxolone is associated with undesirable side effects or has characteristics that are unexpected, we may need to abandon its 
development or limit development to certain uses or subpopulations in which the undesirable side effects or other characteristics are less 
prevalent, less severe or more acceptable from a risk-benefit perspective. Many compounds that initially showed promise in early stage testing for 
treating the target indications for ganaxolone have later been found to cause side effects that prevented further development of the compound. As 
a result of these and other risks described herein that are inherent in the development of novel therapeutic agents, we may never successfully 
develop, enter into or maintain third-party licensing or collaboration transactions with respect to, or successfully commercialize, ganaxolone, in 
which case we will not achieve profitability and the value of our stock may decline.  

Clinical development of product candidates involves a lengthy and expensive process with an uncertain outcome.  

Clinical testing is expensive, can take many years to complete, and its outcome is inherently uncertain. Failure can occur at any time 

during the clinical trial process.  

We may experience delays in our ongoing or future clinical trials and we do not know whether planned clinical trials will begin or enroll 
subjects on time, need to be redesigned or be completed on schedule, if at all. There can be no assurance that the FDA or other foreign regulatory 
authorities will not put clinical trials of ganaxolone on clinical hold now or in the future. Clinical trials may be delayed, suspended or prematurely 
terminated for a variety of reasons, such as:  

•                   delay or failure in reaching agreement with the FDA or a comparable foreign regulatory authority on a trial design that we are able 

to execute;  

•                   delay or failure in obtaining authorization to commence a trial or inability to comply with conditions imposed by a regulatory 

authority regarding the scope or design of a clinical trial;  

•                   delay or failure in reaching agreement on acceptable terms with prospective clinical research organizations, or CROs, and clinical 
trial sites, the terms of which can be subject to extensive negotiation and may vary significantly among different CROs and trial 
sites;  

•                   delay or failure in obtaining institutional review board, or IRB, approval or the approval of other reviewing entities, including 

comparable foreign regulatory authorities, to conduct a clinical trial at each site;

Table of Contents  

•                   withdrawal of clinical trial sites from our clinical trials as a result of changing standards of care or the ineligibility of a site to 

participate in our clinical trials;  

•                   delay or failure in recruiting and enrolling suitable study subjects to participate in a trial;  

•                   delay or failure in study subjects completing a trial or returning for post-treatment follow-up;  

•                   clinical sites and investigators deviating from a trial protocol, failing to conduct the trial in accordance with regulatory requirements, 

or dropping out of a trial;  

•                   inability to identify and maintain a sufficient number of trial sites, many of which may already be engaged in other clinical trial 

programs, including some that may be for competing product candidates with the same indication;  

•                   failure of our third-party clinical trial managers to satisfy their contractual duties or meet expected deadlines;  

•                   delay or failure in adding new clinical trial sites;  

•                   ambiguous or negative interim results or results that are inconsistent with earlier results;  

•                   feedback from the FDA, the IRB, data safety monitoring boards, or a comparable foreign regulatory authority, or results from earlier 

stage or concurrent preclinical studies and clinical trials, that might require modification to the protocol for the trial;  

•                   decision by the FDA, the IRB, a comparable foreign regulatory authority, or us, or recommendation by a data safety monitoring 

board or comparable foreign regulatory authority, to suspend or terminate clinical trials at any time for safety issues or for any other 
reason;  

•                   unacceptable risk-benefit profile, unforeseen safety issues or adverse side effects or adverse events;  

•                   failure of a product candidate to demonstrate any benefit;  

•                   difficulties in manufacturing or obtaining from third parties sufficient quantities of a product candidate for use in clinical trials;  

•                   lack of adequate funding to continue the clinical trial, including the incurrence of unforeseen costs due to enrollment delays, 

requirements to conduct additional clinical trials or increased expenses associated with the services of our CROs and other third 
parties;  

•                   political developments that affect our ability to develop and obtain approval for ganaxolone, or license rights to develop and obtain 

approval for ganaxolone, in a foreign country; or  

•                   changes in governmental regulations or administrative actions.  

Study subject enrollment, a significant factor in the timing of clinical trials, is affected by many factors including the size and nature of 

the subject population, the proximity of subjects to clinical sites, the eligibility criteria for the trial, the design of the clinical trial, ability to obtain 
and maintain subject consents, risk that enrolled subjects will drop out before completion, competing clinical trials and clinicians’ and subjects’ 
perceptions as to the potential advantages of the product candidate being studied in relation to other available therapies, including any new drugs 
that may be approved or product candidates that may be studied in competing clinical trials for the indications we are investigating. We rely on 
CROs and clinical trial sites to ensure the proper and timely conduct of our clinical trials, and while we have agreements governing their 
committed activities, we have limited influence over their actual performance.  

If we experience delays in the completion of any clinical trial of ganaxolone, the commercial prospects of ganaxolone may be harmed, 

and our ability to generate product revenue from ganaxolone, if approved, will be delayed. In addition, any delays in completing our clinical trials 
will increase our costs, slow down our development and approval process for ganaxolone and jeopardize our ability to commence product sales 
and generate revenues. In

Table of Contents  

addition, many of the factors that could cause a delay in the commencement or completion of clinical trials may also ultimately lead to the denial 
of regulatory approval of ganaxolone.  

Ganaxolone may cause undesirable side effects or have other properties that could delay or prevent its regulatory approval, limit the 
commercial profile of an approved label, or result in significant negative consequences following any marketing approval.  

Undesirable side effects caused by ganaxolone could cause us or regulatory authorities to interrupt, delay or halt clinical trials and could 

result in a restrictive label or the delay or denial of regulatory approval by the FDA or other comparable foreign regulatory authority. Although 
ganaxolone has generally been well tolerated by subjects in our earlier-stage clinical trials, in some cases there were side effects, and some of the 
side effects were severe. Specifically, in our most recently completed clinical trial, where ganaxolone was administered as an adjunctive to 
standard therapy in adult subjects with focal onset seizures, the most frequent side effects (those reported in greater than 5% of ganaxolone 
subjects) were dizziness, fatigue and somnolence (or drowsiness). More side effects of the Central Nervous System, or CNS, were categorized as 
severe as compared to side effects of other body systems, though no specific CNS side effect was reported as severe by more than one subject.  

If these side effects are reported in future clinical trials, or if other safety or toxicity issues are reported in our future clinical trials, we 
may not receive approval to market ganaxolone, which could prevent us from ever generating revenue or achieving profitability. Furthermore, 
although we are currently developing ganaxolone for three indications, negative safety findings in any one indication could force us to delay or 
discontinue development in other indications. Results of our clinical trials could reveal an unacceptably high severity and prevalence of side 
effects. In such an event, our clinical trials could be suspended or terminated and the FDA or comparable foreign regulatory authorities could 
order us to cease further development, or deny approval, of ganaxolone for any or all targeted indications. Drug-related side effects could affect 
study subject recruitment or the ability of enrolled subjects to complete our future clinical trials and may result in potential product liability 
claims.  

Additionally, if ganaxolone receives marketing approval, and we or others later identify undesirable side effects caused by ganaxolone, a 

number of potentially significant negative consequences could result, including:  

•                   we may be forced to suspend marketing of ganaxolone;  

•                   regulatory authorities may withdraw their approvals of ganaxolone;  

•                   regulatory authorities may require additional warnings on the label that could diminish the usage or otherwise limit the commercial 

success of ganaxolone;  

•                   we may be required to conduct post-marketing studies;  

•                   we could be sued and held liable for harm caused to subjects or patients; and  

•                   our reputation may suffer.  

Any of these events could prevent us from achieving or maintaining market acceptance of ganaxolone, if approved.  

Even if ganaxolone receives regulatory approval, we may still face future development and regulatory difficulties.  

Even if we obtain regulatory approval for ganaxolone, it would be subject to ongoing requirements by the FDA and comparable foreign 

regulatory authorities governing the manufacture, quality control, further development, labeling, packaging, storage, distribution, safety 
surveillance, import, export, advertising, promotion, recordkeeping and reporting of safety and other post-market information. The safety profile 
of ganaxolone will continue to be closely monitored by the FDA and comparable foreign regulatory authorities after approval. If new safety 
information becomes available after approval of ganaxolone, the FDA or comparable foreign regulatory authorities may require labeling changes 
or establishment of a Risk Evaluation and Mitigation Strategy, or REMS, or similar strategy, impose significant restrictions on ganaxolone’s 
indicated uses or marketing, or impose ongoing requirements for potentially costly post-approval studies or post-market surveillance. For 
example, the label ultimately approved for ganaxolone, if it achieves marketing approval, may include restrictions on use.

In addition, manufacturers of drug products and their facilities are subject to continual review and periodic inspections by the FDA and 

other regulatory authorities for compliance with current good manufacturing practices, or cGMP, and other regulations. If we or a regulatory 
authority discover previously unknown problems with a product, such as adverse events of unanticipated severity or frequency, or problems with 
the facility where the product is manufactured, a regulatory authority may impose restrictions on that product, the manufacturing facility or us, 
including requiring recall or withdrawal of the product from the market or suspension of manufacturing. If we, ganaxolone or the manufacturing 
facilities for ganaxolone fail to comply with applicable regulatory requirements, a regulatory authority may:  

•                   issue warning letters or untitled letters;  

•                   mandate modifications to promotional materials or require us to provide corrective information to healthcare practitioners;  

•                   require us to enter into a consent decree, which can include imposition of various fines, reimbursements for inspection costs, 

required due dates for specific actions and penalties for noncompliance;  

•                   seek an injunction or impose civil or criminal penalties or monetary fines;  

•                   suspend or withdraw regulatory approval;  

•                   suspend any ongoing clinical trials;  

•                   refuse to approve pending applications or supplements to applications filed by us;  

•                   suspend or impose restrictions on operations, including costly new manufacturing requirements; or  

•                   seize or detain products, refuse to permit the import or export of products, or require us to initiate a product recall.  

The occurrence of any event or penalty described above may inhibit or preclude our ability to commercialize ganaxolone and generate 

revenue.  

The FDA’s and other regulatory authorities’ policies may change, and additional government regulations may be enacted that could 

prevent, limit or delay regulatory approval of ganaxolone. We cannot predict the likelihood, nature or extent of government regulation that may 
arise from future legislation or administrative action, either in the United States or abroad. If we are slow or unable to adapt to changes in existing 
requirements or the adoption of new requirements or policies, or if we are not able to maintain regulatory compliance, we may lose any marketing 
approval that we may have obtained, and we may not achieve or sustain profitability, which would adversely affect our business, prospects, 
financial condition and results of operations.  

Advertising and promotion of any product candidate that obtains approval in the United States will be heavily scrutinized by, among 
others, the FDA, the Department of Justice, or the DOJ, the Office of Inspector General of the Department of Health and Human Services, or 
HHS, state attorneys general, members of Congress and the public. Violations, including promotion of our products for unapproved or off-label 
uses, are subject to enforcement letters, inquiries and investigations, and civil and criminal sanctions by the FDA or other government agencies. 
Additionally, advertising and promotion of any product candidate that obtains approval outside of the United States will be heavily scrutinized by 
comparable foreign regulatory authorities.  

In the United States, engaging in impermissible promotion of ganaxolone for off-label uses can also subject us to false claims litigation 
under federal and state statutes, and other litigation and/or investigation, which can lead to civil and criminal penalties and fines and agreements 
that materially restrict the manner in which we promote or distribute our drug products. These false claims statutes include the federal False 
Claims Act, which allows any individual to bring a lawsuit against a pharmaceutical company on behalf of the federal government alleging 
submission of false or fraudulent claims, or causing to present such false or fraudulent claims, for payment by a federal program such as Medicare 
or Medicaid. If the government prevails in the lawsuit, the individual will share in any fines or settlement funds. Since 2004, these False Claims 
Act lawsuits against pharmaceutical companies have increased significantly in volume and breadth, leading to several substantial civil and 
criminal settlements based on certain sales practices promoting off-label drug uses. This increasing focus and scrutiny has increased the risk that a  

33  

   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
 
Table of Contents  

pharmaceutical company will have to defend a false claim action, pay settlement fines or restitution, agree to comply with burdensome reporting 
and compliance obligations, and be excluded from the Medicare, Medicaid and other federal and state healthcare programs. If we do not lawfully 
promote our approved products, we may become subject to such litigation and/or investigation and, if we are not successful in defending against 
such actions, those actions could compromise our ability to become profitable.  

Failure to obtain regulatory approval in international jurisdictions would prevent ganaxolone from being marketed in these jurisdictions.  

In order to market and sell our products in the European Union and many other jurisdictions, we must obtain separate marketing 

approvals and comply with numerous and varying regulatory requirements. The approval procedure varies among countries and can involve 
additional testing. The time required to obtain approval may differ substantially from that required to obtain FDA approval. The regulatory 
approval process outside the United States generally includes all of the risks associated with obtaining FDA approval. In addition, in many 
countries outside the United States, it is required that the product be approved for reimbursement before the product can be approved for sale in 
that country. We may not obtain approvals from regulatory authorities outside the United States on a timely basis, if at all. Approval by the FDA 
does not ensure approval by regulatory authorities in other countries or jurisdictions, and approval by one regulatory authority outside the United 
States does not ensure approval by regulatory authorities in other countries or jurisdictions or by the FDA. We may not be able to file for 
marketing approvals and may not receive necessary approvals to commercialize our products in any market. If we are unable to obtain approval of 
ganaxolone by regulatory authorities in the European Union or another country or jurisdiction, the commercial prospects of ganaxolone may be 
significantly diminished and our business prospects could decline.  

We may not be able to obtain orphan drug exclusivity for ganaxolone or any other product candidates for which we seek it, which could limit 
the potential profitability of ganaxolone or such other product candidates.  

Regulatory authorities in some jurisdictions, including the United States and Europe, may designate drugs for relatively small patient 
populations as orphan drugs. Under the Orphan Drug Act, the FDA may designate a product as an orphan drug if it is a drug intended to treat a 
rare disease or condition, which is generally defined as a patient population of fewer than 200,000 individuals in the United States. Generally, if a 
product with an orphan drug designation subsequently receives the first marketing approval for an indication for which it receives the designation, 
then the product is entitled to a period of marketing exclusivity that precludes the applicable regulatory authority from approving another 
marketing application for the same drug for the same indication for the exclusivity period except in limited situations. For purposes of small 
molecule drugs, the FDA defines “same drug” as a drug that contains the same active moiety and is intended for the same use as the drug in 
question. A designated orphan drug may not receive orphan drug exclusivity if it is approved for a use that is broader than the indication for which 
it received orphan designation.  

We expect that we may in the future pursue orphan drug designations for ganaxolone for one or more indications, including behaviors in 

FXS and the treatment of PCDH19 female pediatric epilepsy, as well as certain of our future product candidates. However, obtaining an orphan 
drug designation can be difficult and we may not be successful in doing so for ganaxolone or any of our future product candidates. Even if we 
were to obtain orphan drug exclusivity for a product candidate, that exclusivity may not effectively protect the product from the competition of 
different drugs for the same condition, which could be approved during the exclusivity period. Additionally, after an orphan drug is approved, the 
FDA could subsequently approve another application for the same drug for the same indication if the FDA concludes that the later drug is shown 
to be safer, more effective or makes a major contribution to patient care. Orphan drug exclusive marketing rights in the United States also may be 
lost if the FDA later determines that the request for designation was materially defective or if the manufacturer is unable to assure sufficient 
quantity of the drug to meet the needs of patients with the rare disease or condition. The failure to obtain an orphan drug designation for any 
product candidates we may develop, the inability to maintain that designation for the duration of the applicable period, or the inability to obtain or 
maintain orphan drug exclusivity could reduce our ability to make sufficient sales of the applicable product candidate to balance our expenses 
incurred to develop it, which would have a negative impact on our operational results and financial condition.

Our business and operations would suffer in the event of computer system failures.  

Despite the implementation of security measures, our internal computer systems, and those of our CROs and other third parties on which 

we rely, are vulnerable to damage from computer viruses, unauthorized access, natural disasters, fire, terrorism, war and telecommunication and 
electrical failures. In addition, our systems safeguard important confidential personal data regarding subjects enrolled in our clinical trials. If a 
disruption event were to occur and cause interruptions in our operations, it could result in a material disruption of our drug development programs. 
For example, the loss of clinical trial data from completed, ongoing or planned clinical trials could result in delays in our regulatory approval 
efforts and significantly increase our costs to recover or reproduce the data. To the extent that any disruption or security breach results in a loss of 
or damage to our data or applications, or inappropriate disclosure of confidential or proprietary information, we could incur liability and the 
further development of ganaxolone could be delayed.  

Business disruptions could seriously harm our future revenue and financial condition and increase our costs and expenses.  

Our operations could be subject to earthquakes, power shortages, telecommunications failures, water shortages, floods, hurricanes, 

typhoons, fires, extreme weather conditions, medical epidemics and other natural or man-made disasters or business interruptions, for which we 
are predominantly self-insured. The occurrence of any of these business disruptions could seriously harm our operations and financial condition 
and increase our costs and expenses. We rely on third-party manufacturers to produce ganaxolone. Our ability to obtain clinical supplies of 
ganaxolone could be disrupted if the operations of these suppliers are affected by a man-made or natural disaster or other business interruption. 
The ultimate impact on us, our significant suppliers and our general infrastructure of being in certain geographical areas is unknown, but our 
operations and financial condition could suffer in the event of a major earthquake, fire or other natural disaster.  

Risks Related to the Commercialization of Our Product  

Our commercial success depends upon attaining significant market acceptance of ganaxolone, if approved, among physicians, patients, 
government and private payors and others in the medical community.  

Even if ganaxolone receives regulatory approval, it may not gain market acceptance among physicians, patients, government and private 
payors, or others in the medical community. Market acceptance of ganaxolone, if we receive approval, depends on a number of factors, including 
the:  

•                   efficacy and safety of ganaxolone, or ganaxolone administered with other drugs, each as demonstrated in clinical trials and post-

marketing experience;  

•                   clinical indications for which ganaxolone is approved;  

•                   acceptance by physicians and patients of ganaxolone as a safe and effective treatment;  

•                   potential and perceived advantages of ganaxolone over alternative treatments;  

•                   safety of ganaxolone seen in a broader patient group, including its use outside the approved indications should physicians choose to 

prescribe for such uses;  

•                   prevalence and severity of any side effects;  

•                   product labeling or product insert requirements of the FDA or other regulatory authorities;  

•                   timing of market introduction of ganaxolone as well as competitive products;  

•                   cost of treatment in relation to alternative treatments;  

•                   availability of coverage and adequate reimbursement and pricing by government and private payors;  

•                   relative convenience and ease of administration; and  

•                   effectiveness of our sales and marketing efforts.

If ganaxolone is approved but fails to achieve market acceptance among physicians, patients, government or private payors or others in 
the medical community, or the products or product candidates that are being administered with ganaxolone are restricted, withdrawn or recalled, 
or fail to be approved, as the case may be, we may not be able to generate significant revenues, which would compromise our ability to become 
profitable.  

If we are unable to establish sales and marketing capabilities or enter into agreements with third parties to market and sell ganaxolone, we 
may be unable to generate any revenue.  

We do not currently have an organization for the sale, marketing and distribution of pharmaceutical products and the cost of establishing 
and maintaining such an organization may exceed the cost-effectiveness of doing so. In order to market any products that may be approved by the 
FDA and comparable foreign regulatory authorities, we must build our sales, marketing, managerial and other non-technical capabilities or make 
arrangements with third parties to perform these services. If we are unable to establish adequate sales, marketing and distribution capabilities, 
whether independently or with third parties, we may not be able to generate product revenue and may not become profitable. We will be 
competing with many companies that currently have extensive and well-funded sales and marketing operations. Without an internal commercial 
organization or the support of a third party to perform sales and marketing functions, we may be unable to compete successfully against these 
more established companies. To the extent we rely on third parties to commercialize ganaxolone, if approved, we may have little or no control 
over the marketing and sales efforts of such third parties, and our revenues from product sales may be lower than if we had commercialized 
ganaxolone ourselves.  

A variety of risks associated with marketing ganaxolone internationally could materially adversely affect our business.  

We plan to seek regulatory approval for ganaxolone outside of the United States, and, accordingly, we expect that we will be subject to 

additional risks related to operating in foreign countries if we obtain the necessary approvals, including:  

•                   differing regulatory requirements in foreign countries;  

•                   the potential for so-called parallel importing, which is what happens when a local seller, faced with high or higher local prices, opts 

to import goods from a foreign market (with low or lower prices) rather than buying them locally;  

•                   unexpected changes in tariffs, trade barriers, price and exchange controls and other regulatory requirements;  

•                   economic weakness, including inflation, or political instability in particular foreign economies and markets;  

•                   compliance with tax, employment, immigration and labor laws for employees living or traveling abroad;  

•                   foreign taxes, including withholding of payroll taxes;  

•                   foreign currency fluctuations, which could result in increased operating expenses and reduced revenues, and other obligations 

incident to doing business in another country;  

•                   difficulties staffing and managing foreign operations;  

•                   workforce uncertainty in countries where labor unrest is more common than in the United States;  

•                   challenges enforcing our contractual and intellectual property rights, especially in those foreign countries that do not respect and 

protect intellectual property rights to the same extent as the United States;  

•                   production shortages resulting from any events affecting raw material supply or manufacturing capabilities abroad; and  

•                   business interruptions resulting from geo-political actions, including war and terrorism.

These and other risks associated with our international operations may materially adversely affect our ability to attain or maintain 

profitable operations.  

Even if we are able to commercialize ganaxolone, it may not receive coverage and adequate reimbursement from third-party payors, which 
could harm our business.  

Our ability to commercialize ganaxolone successfully will depend, in part, on the extent to which coverage and adequate reimbursement 

for ganaxolone and related treatments will be available from government health administration authorities, private health insurers and other 
organizations. Government authorities and third-party payors, such as private health insurers and health maintenance organizations, determine 
which medications they will cover and establish reimbursement levels. A primary trend in the United States healthcare industry and elsewhere is 
cost containment. Government authorities and third- party payors have attempted to control costs by limiting coverage and the amount of 
reimbursement for particular medications. Increasingly, third-party payors are requiring that drug companies provide them with predetermined 
discounts from list prices and are challenging the prices charged for drugs. Third-party payors may also seek additional clinical evidence, beyond 
the data required to obtain marketing approval, demonstrating clinical benefits and value in specific patient populations before covering 
ganaxolone for those patients. We cannot be sure that coverage and adequate reimbursement will be available for ganaxolone and, if 
reimbursement is available, what the level of reimbursement will be. Coverage and reimbursement may impact the demand for, or the price of, 
ganaxolone, if we obtain marketing approval. If reimbursement is not available or is available only at limited levels, we may not be able to 
successfully commercialize ganaxolone even if we obtain marketing approval.  

There may be significant delays in obtaining coverage and reimbursement for newly approved drugs, and coverage may be more limited 
than the purposes for which the drug is approved by the FDA or comparable foreign regulatory authorities. Moreover, eligibility for coverage and 
reimbursement does not imply that any drug will be paid for in all cases or at a rate that covers our costs, including research, development, 
manufacture, sale and distribution. Interim reimbursement levels for new drugs, if applicable, may also not be sufficient to cover our costs and 
may only be temporary. Reimbursement rates may vary according to the use of the drug and the clinical setting in which it is used, may be based 
on reimbursement levels already set for lower cost drugs and may be incorporated into existing payments for other services. Net prices for drugs 
may be reduced by mandatory discounts or rebates required by government healthcare programs or private payors and by any future relaxation of 
laws that presently restrict imports of drugs from countries where they may be sold at lower prices than in the United States. Third-party payors 
often rely upon Medicare coverage policy and payment limitations in setting their own reimbursement policies. Our inability to obtain coverage 
and profitable reimbursement rates from both government-funded and private payors for any approved products that we develop could have a 
material adverse effect on our operating results, our ability to raise capital needed to commercialize products and our overall financial condition.  

We face substantial competition, which may result in others discovering, developing or commercializing products before or more successfully 
than we do.  

The development and commercialization of new drug products is highly competitive. We face competition with respect to ganaxolone 
and will face competition with respect to any other product candidates that we may seek to develop or commercialize in the future, from major 
pharmaceutical companies, specialty pharmaceutical companies and biotechnology companies worldwide. There are a number of large 
pharmaceutical and biotechnology companies that currently market and sell products or are pursuing the development of products for the 
treatment of the disease indications for which we are developing ganaxolone. Some of these competitive products and therapies are based on 
scientific approaches that are the same as, or similar to, our approach, and others are based on entirely different approaches. For example, there are 
 neuroreceptor that we are targeting 
several companies developing product candidates that target the same gamma-aminobutyric acid, or GABA 
or that are testing product candidates in the same indications that we are testing. Potential competitors also include academic institutions, 
government agencies and other public and private research organizations that conduct research, seek patent protection and establish collaborative 
arrangements for research, development, manufacturing and commercialization.  

A, 

Ganaxolone is presently being developed primarily as a neuropsychiatric therapeutic. There are a variety of available marketed therapies 
available for these patients. Some of these other drugs are branded and subject to patent protection, some are in clinical development and not yet 
approved, and others are available on a generic basis.  

Specifically, there are more than 15 approved antiepileptic drugs, or AEDs, available in the United States and worldwide, including the 

generic products levetiracetam, lamotrigine, carbamazepine, oxcarbazepine, valproic  

37  

   
   
   
   
   
   
   
   
   
 
Table of Contents  

acid and topiramate. Recent market entrants include branded products developed by UCB, GlaxoSmithKline, Eisai, and Sunovion 
Pharmaceuticals. Additionally, there are several drugs in development for the treatment of behavioral and mental health conditions associated with 
FXS, including compounds being developed by Roche, Sunovion Pharmaceuticals, Afraxis, Alcobra and Neuren Pharmaceuticals.  

Many of the approved drugs are well established therapies or products and are widely accepted by physicians, patients and third-party 

payors. Insurers and other third-party payors may also encourage the use of generic products. These factors may make it difficult for us to achieve 
market acceptance at desired levels or in a timely manner to ensure viability of our business.  

More established companies may have a competitive advantage over us due to their greater size, cash flows and institutional experience. 

Compared to us, many of our competitors may have significantly greater financial, technical and human resources.  

As a result of these factors, our competitors may obtain regulatory approval of their products before we are able to, which may limit our 

ability to develop or commercialize ganaxolone. Our competitors may also develop drugs that are safer, more effective, more widely used and 
cheaper than ours, and may also be more successful than us in manufacturing and marketing their products. These appreciable advantages could 
render ganaxolone obsolete or non-competitive before we can recover the expenses of ganaxolone’s development and commercialization.  

Mergers and acquisitions in the pharmaceutical and biotechnology industries may result in even more resources being concentrated 

among a smaller number of our competitors. Smaller and other early-stage companies may also prove to be significant competitors, particularly 
through collaborative arrangements with large and established companies. These third parties compete with us in recruiting and retaining qualified 
scientific, management and commercial personnel, establishing clinical trial sites and subject registration for clinical trials, as well as in acquiring 
technologies complementary to, or necessary for, our programs.  

Product liability lawsuits against us could cause us to incur substantial liabilities and to limit commercialization of ganaxolone or other 
product candidates that we may develop.  

We face an inherent risk of product liability exposure related to the testing of ganaxolone by us or our investigators in human clinical 
trials and will face an even greater risk if ganaxolone receives regulatory approval and we commercially sell ganaxolone after obtaining such 
regulatory approval. Product liability claims may be brought against us by study subjects enrolled in our clinical trials, patients, healthcare 
providers or others using, administering or selling ganaxolone. If we cannot successfully defend ourselves against claims that ganaxolone caused 
injuries, we could incur substantial liabilities. Regardless of merit or eventual outcome, liability claims may result in, for example:  

•                   decreased demand for ganaxolone;  

•                   termination of clinical trial sites or entire trial programs;  

•                   injury to our reputation and significant negative media attention;  

•                   withdrawal of clinical trial subjects;  

•                   significant costs to defend the related litigation;  

•                   substantial monetary awards to clinical trial subjects or patients;  

•                   loss of revenue;  

•                   diversion of management and scientific resources from our business operations;  

•                   the inability to commercialize ganaxolone; and  

•                   increased scrutiny and potential investigation by, among others, the FDA, the DOJ, the Office of Inspector General of the HHS, 

state attorneys general, members of Congress and the public.

We currently have $10.0 million in product liability insurance coverage in the aggregate, which may not be adequate to cover all 

liabilities that we may incur. Insurance coverage is increasingly expensive. We may not be able to maintain insurance coverage at a reasonable 
cost or in an amount adequate to satisfy any liability that may arise. We intend to expand our product liability insurance coverage to include the 
sale of commercial products if we obtain marketing approval for ganaxolone, but we may be unable to obtain commercially reasonable product 
liability insurance for ganaxolone, if approved for marketing. Large judgments have been awarded in class action lawsuits based on drugs that had 
unanticipated side effects. A successful product liability claim or series of claims brought against us, particularly if judgments exceed our 
insurance coverage, could decrease our cash and adversely affect our business.  

Risks Related to Our Dependence on Third Parties  

We rely on third parties to conduct our preclinical studies and clinical trials. If these third parties do not successfully carry out their 
contractual duties or meet expected deadlines, we may not be able to obtain regulatory approval for or commercialize ganaxolone.  

We rely on third-party CROs to monitor and manage data for our ongoing preclinical and clinical programs. We rely on these parties for 

execution of our preclinical studies and clinical trials, and we control only some aspects of their activities. Nevertheless, we are responsible for 
ensuring that each of our preclinical studies and clinical trials are conducted in accordance with the applicable protocol and legal, regulatory and 
scientific requirements and standards, and our reliance on the CROs does not relieve us of our regulatory responsibilities. We also rely on third 
parties to assist in conducting our preclinical studies in accordance with Good Laboratory Practices, or GLP, and the Animal Welfare Act 
requirements. We and our CROs are required to comply with federal regulations and Good Clinical Practices, or GCP, which are international 
requirements meant to protect the rights and health of subjects that are enforced by the FDA, the Competent Authorities of the Member States of 
the European Economic Area and comparable foreign regulatory authorities for ganaxolone and any future product candidates in clinical 
development. Regulatory authorities enforce GCP through periodic inspections of trial sponsors, principal investigators and trial sites. If we or any 
of our CROs fail to comply with applicable GCP, the clinical data generated in our clinical trials may be deemed unreliable and the FDA or 
comparable foreign regulatory authorities may require us to perform additional clinical trials before approving our marketing applications. We 
cannot assure you that upon inspection by a given regulatory authority, such regulatory authority will determine that any of our clinical trials 
comply with GCP requirements. In addition, our clinical trials must be conducted with product produced under cGMP requirements. Failure to 
comply with these regulations may require us to repeat preclinical studies and clinical trials, which would delay the regulatory approval process.  

Our CROs are not our employees, and except for remedies available to us under our agreements with such CROs, we cannot control 

whether or not they devote sufficient time and resources to our ongoing clinical, nonclinical and preclinical programs. If CROs do not successfully 
carry out their contractual duties or obligations or meet expected deadlines or if the quality or accuracy of the data they obtain is compromised due 
to the failure to adhere to our protocols, regulatory requirements or for other reasons, our preclinical studies and clinical trials may be extended, 
delayed or terminated and we may not be able to obtain regulatory approval for or successfully commercialize ganaxolone. As a result, our results 
of operations and the commercial prospects for ganaxolone would be harmed, our costs could increase and our ability to generate revenue could 
be delayed.  

Because we have relied on third parties, our internal capacity to perform these functions is limited. Outsourcing these functions involves 
risk that third parties may not perform to our standards, may not produce results in a timely manner or may fail to perform at all. In addition, the 
use of third-party service providers requires us to disclose our proprietary information to these parties, which could increase the risk that this 
information will be misappropriated. We currently have a small number of employees, which limits the internal resources we have available to 
identify and monitor our third-party providers. To the extent we are unable to identify and successfully manage the performance of third-party 
service providers in the future, our business may be adversely affected. Though we carefully manage our relationships with our CROs, there can 
be no assurance that we will not encounter challenges or delays in the future or that these delays or challenges will not have a material adverse 
impact on our business, financial condition and prospects.  

If we lose our relationships with CROs, our drug development efforts could be delayed.  

We rely on third-party vendors and CROs for preclinical studies and clinical trials related to our drug development efforts. Switching or 
adding additional CROs would involve additional cost and requires management time and focus. Our CROs generally have the right to terminate 
their agreements with us in the event of an uncured  

39  

   
   
   
   
   
   
   
   
   
 
Table of Contents  

material breach. In addition, some of our CROs have an ability to terminate their respective agreements with us, or research projects pursuant to 
such agreements, if, in the reasonable opinion of the relevant CRO, the safety of the subjects participating in our clinical trials warrants such 
termination. These agreements or research projects may also be terminated if we make a general assignment for the benefit of our creditors or if 
we are liquidated. Identifying, qualifying and managing performance of third-party service providers can be difficult, time consuming and cause 
delays in our development programs. In addition, there is a natural transition period when a new CRO commences work and the new CRO may 
not provide the same type or level of services as the original provider. If any of our relationships with our third-party CROs terminate, we may not 
be able to enter into arrangements with alternative CROs or to do so on commercially reasonable terms.  

Our experience manufacturing ganaxolone is limited to the needs of our preclinical studies and clinical trials. We have no experience 
manufacturing ganaxolone on a commercial scale and have no manufacturing facility. We are dependent on third-party manufacturers for 
the manufacture of ganaxolone as well as on third parties for our supply chain, and if we experience problems with any such third parties, the 
manufacturing of ganaxolone could be delayed.  

We do not own or operate facilities for the manufacture of ganaxolone. We currently have no plans to build our own clinical or 
commercial scale manufacturing capabilities. We currently rely on contract manufacturing organizations, or CMOs, for the chemical manufacture 
of active pharmaceutical ingredients for ganaxolone and another CMO for the production of the ganaxolone nanoparticulate formulation into 
capsules. To meet our projected needs for preclinical and clinical supplies to support our activities through regulatory approval and commercial 
manufacturing, the CMOs with whom we currently work will need to increase the scale of production. We may need to identify additional CMOs 
for continued production of supply for ganaxolone. Although alternative third-party suppliers with the necessary manufacturing and regulatory 
expertise and facilities exist, it could be expensive and take a significant amount of time to arrange for alternative suppliers. If we are unable to 
arrange for alternative third-party manufacturing sources on commercially reasonable terms, in a timely manner or at all, we may not be able to 
complete development of ganaxolone, or market or distribute ganaxolone.  

Reliance on third-party manufacturers entails risks to which we would not be subject if we manufactured ganaxolone ourselves, including 

reliance on the third party for regulatory compliance and quality assurance, the possibility of breach of the manufacturing agreement by the third 
party because of factors beyond our control, including a failure to synthesize and manufacture ganaxolone or any products we may eventually 
commercialize in accordance with our specifications, and the possibility of termination or nonrenewal of the agreement by the third party, based 
on its own business priorities, at a time that is costly or damaging to us. In addition, the FDA and other regulatory authorities would require that 
ganaxolone and any products that we may eventually commercialize be manufactured according to cGMP and similar foreign standards. Any 
failure by our third-party manufacturers to comply with cGMP or failure to scale up manufacturing processes, including any failure to deliver 
sufficient quantities of ganaxolone in a timely manner, could lead to a delay in, or failure to obtain, regulatory approval of ganaxolone. In 
addition, such failure could be the basis for the FDA to issue a warning letter, withdraw approvals for ganaxolone previously granted to us, or take 
other regulatory or legal action, including recall or seizure of outside supplies of ganaxolone, total or partial suspension of production, suspension 
of ongoing clinical trials, refusal to approve pending applications or supplemental applications, detention of product, refusal to permit the import 
or export of products, injunction, or imposing civil and criminal penalties.  

Any significant disruption in our supplier relationships could harm our business. Any significant delay in the supply of ganaxolone or its 
key materials for an ongoing preclinical study or clinical trial could considerably delay completion of our preclinical study or clinical trial, product 
testing and potential regulatory approval of ganaxolone. If our manufacturers or we are unable to purchase these key materials after regulatory 
approval has been obtained for ganaxolone, the commercial launch of ganaxolone would be delayed or there would be a shortage in supply, which 
would impair our ability to generate revenues from the sale of ganaxolone.  

We may elect to enter into licensing or collaboration agreements to partner ganaxolone in territories currently retained by us. Our dependence 
on such relationships may adversely affect our business.  

Because we have limited resources, we may seek to enter into collaboration agreements with other pharmaceutical or biotechnology 

companies. Any failure by our partners to perform their obligations or any decision by our partners to terminate these agreements could negatively 
impact our ability to successfully develop, obtain regulatory approvals for and commercialize ganaxolone. In the event we grant exclusive rights 
to such partners, we would be precluded from potential commercialization of ganaxolone within the territories in which we have a partner. In 
addition, any termination of our collaboration agreements will terminate the funding we may receive  

40  

   
   
   
   
   
   
   
   
 
Table of Contents  

under the relevant collaboration agreement and may impair our ability to fund further development efforts and our progress in our development 
programs.  

Our commercialization strategy for ganaxolone may depend on our ability to enter into agreements with collaborators to obtain assistance 
and funding for the development and potential commercialization of ganaxolone in the territories in which we seek to partner. Despite our efforts, 
we may be unable to secure additional collaborative licensing or other arrangements that are necessary for us to further develop and 
commercialize ganaxolone. Supporting diligence activities conducted by potential collaborators and negotiating the financial and other terms of a 
collaboration agreement are long and complex processes with uncertain results. Even if we are successful in entering into one or more 
collaboration agreements, collaborations may involve greater uncertainty for us, as we have less control over certain aspects of our collaborative 
programs than we do over our proprietary development and commercialization programs. We may determine that continuing a collaboration under 
the terms provided is not in our best interest, and we may terminate the collaboration. Our potential future collaborators could delay or terminate 
their agreements, and as a result ganaxolone may never be successfully commercialized.  

Further, our potential future collaborators may develop alternative products or pursue alternative technologies either on their own or in 
collaboration with others, including our competitors, and the priorities or focus of our collaborators may shift such that ganaxolone receives less 
attention or resources than we would like, or they may be terminated altogether. Any such actions by our potential future collaborators may 
adversely affect our business prospects and ability to earn revenue. In addition, we could have disputes with our potential future collaborators, 
such as the interpretation of terms in our agreements. Any such disagreements could lead to delays in the development or commercialization of 
ganaxolone or could result in time-consuming and expensive litigation or arbitration, which may not be resolved in our favor.  

Government funding for certain of our programs adds uncertainty to our research efforts with respect to those programs and may impose 
requirements that increase the costs of commercialization and production of product candidates developed under those government-funded 
programs.  

Our preclinical studies and clinical trials to evaluate ganaxolone in FXS patients have been conducted with the MIND Institute at the 

University of California, Davis which receives funding from the United States Department of Defense, or the DoD, for such studies and trials. In 
addition, our preclinical studies and clinical trials to evaluate ganaxolone in patients suffering from posttraumatic stress disorder, or PTSD, have 
been primarily conducted by the United States Department of Veterans Affairs, which also receives funding from the DoD. Programs funded by 
the United States government and its agencies, including the DoD, include provisions that reflect the government’s substantial rights and 
remedies, many of which are not typically found in commercial contracts, including powers of the government to:  

•                   terminate agreements, in whole or in part, for any reason or no reason;  

•                   reduce or modify the government’s obligations under such agreements without the consent of the other party;  

•                   claim rights, including intellectual property rights, in products and data developed under such agreements;  

•                   audit contract-related costs and fees, including allocated indirect costs;  

•                   suspend the contractor from receiving new contracts pending resolution of alleged violations of procurement laws or regulations;  

•                   impose United States manufacturing requirements for products that embody inventions conceived or first reduced to practice under 

such agreements;  

•                   suspend or debar the contractor from doing future business with the government; and  

•                   control and potentially prohibit the export of products.  

We may not have the right to prohibit the United States government from using or allowing others to use certain technologies developed 
by us, and we may not be able to prohibit third party companies, including our competitors, from using those technologies in providing products 
and services to the United States government. The

United States government generally obtains the right to royalty-free use of technologies that are developed under United States government 
contracts.  

In addition, government contracts normally contain additional requirements that may increase our costs of doing business, reduce our 

profits, and expose us to liability for failure to comply with these terms and conditions. These requirements include, for example:  

•                   specialized accounting systems unique to government contracts;  

•                   mandatory financial audits and potential liability for price adjustments or recoupment of government funds after such funds have 

been spent;  

•                   public disclosures of certain contract information, which may enable competitors to gain insights into our research program; and  

•                   mandatory socioeconomic compliance requirements, including labor standards, non-discrimination and affirmative action programs 

and environmental compliance requirements.  

If we fail to maintain compliance with these requirements, we may be subject to potential contract liability and to termination of our 

contracts.  

Changes in government budgets and agendas may result in a decreased and de-prioritized emphasis on supporting the development of 
ganaxolone in patients suffering from certain FXS-associated behavioral symptoms. Although we intend to fund a portion of our development 
programs for ganaxolone in patients with FXS, any reduction or delay in DoD funding to our collaborators may force us to suspend or terminate 
these programs or seek alternative funding, which may not be available on non-dilutive terms, terms favorable to us or at all.  

If our third-party manufacturers use hazardous and biological materials in a manner that causes injury or violates applicable law, we may be 
liable for damages.  

Our research and development activities involve the controlled use of potentially hazardous substances, including chemical and 
biological materials by our third-party manufacturers. Our manufacturers are subject to federal, state and local laws and regulations in the United 
States governing the use, manufacture, storage, handling and disposal of medical, radioactive and hazardous materials. Although we believe that 
our manufacturers’ procedures for using, handling, storing and disposing of these materials comply with legally prescribed standards, we cannot 
completely eliminate the risk of contamination or injury resulting from medical, radioactive or hazardous materials. As a result of any such 
contamination or injury we may incur liability or local, city, state or federal authorities may curtail the use of these materials and interrupt our 
business operations. In the event of an accident, we could be held liable for damages or penalized with fines, and the liability could exceed our 
resources. We do not have any insurance for liabilities arising from medical radioactive or hazardous materials. Compliance with applicable 
environmental laws and regulations is expensive, and current or future environmental regulations may impair our research, development and 
production efforts, which could harm our business, prospects, financial condition or results of operations.  

Risks Related to Regulatory Compliance  

Recently enacted and future legislation, including potentially unfavorable pricing regulations or other healthcare reform initiatives, may 
increase the difficulty and cost for us to obtain marketing approval of and commercialize ganaxolone and affect the prices we may obtain.  

The regulations that govern, among other things, marketing approvals, coverage, pricing and reimbursement for new drug products vary 

widely from country to country. In the United States and some foreign jurisdictions, there have been a number of legislative and regulatory 
changes and proposed changes regarding the healthcare system that could prevent or delay marketing approval of ganaxolone, restrict or regulate 
post-approval activities and affect our ability to successfully sell ganaxolone, if we obtain marketing approval.  

In the United States, the Medicare Prescription Drug, Improvement, and Modernization Act of 2003, or Medicare Modernization Act, 

changed the way Medicare covers and pays for pharmaceutical products. The legislation expanded Medicare coverage for drug purchases by the 
elderly and introduced a new reimbursement methodology based on average sales prices for physician administered drugs. In recent years, 
Congress has  

42  

   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
 
Table of Contents  

considered further reductions in Medicare reimbursement for drugs administered by physicians. The Centers for Medicare and Medicaid Services, 
the agency that runs the Medicare program, also has the authority to revise reimbursement rates and to implement coverage restrictions for some 
drugs. Cost reduction initiatives and changes in coverage implemented through legislation or regulation could decrease utilization of and 
reimbursement for any approved products, which in turn would affect the price we can receive for those products. While the Medicare 
Modernization Act and Medicare regulations apply only to drug benefits for Medicare beneficiaries, private payors often follow Medicare 
coverage policy and payment limitations in setting their own reimbursement rates. Therefore, any reduction in reimbursement that results from 
federal legislation or regulation may result in a similar reduction in payments from private payors.  

In March 2010, President Obama signed into law the Patient Protection and Affordable Care Act and the Health Care and Education 

Affordability Reconciliation Act of 2010, or the Affordable Care Act, a sweeping law intended to broaden access to health insurance, reduce or 
constrain the growth of healthcare spending, enhance remedies against fraud and abuse, add new transparency requirements for healthcare and 
health insurance industries, impose new taxes and fees on pharmaceutical and medical device manufacturers and impose additional health policy 
reforms. The Affordable Care Act expanded manufacturers’ rebate liability to include covered drugs dispensed to individuals who are enrolled in 
Medicaid managed care organizations, increased the minimum rebate due for innovator drugs from 15.1% of average manufacturer price, or AMP, 
to 23.1% of AMP and capped the total rebate amount for innovator drugs at 100.0% of AMP. The Affordable Care Act and subsequent legislation 
also changed the definition of AMP. Furthermore, the Affordable Care Act imposes a significant annual, nondeductible fee on companies that 
manufacture or import certain branded prescription drug products. Substantial new provisions affecting compliance have also been enacted, which 
may affect our business practices with healthcare practitioners, and a significant number of provisions are not yet, or have only recently become, 
effective. Although it is too early to determine the effect of the Affordable Care Act, it appears likely to continue the pressure on pharmaceutical 
pricing, especially under the Medicare program, and may also increase our regulatory burdens and operating costs.  

In addition, other legislative changes have been proposed and adopted since the Affordable Care Act was enacted. More recently, in 

August 2011, President Obama signed into law the Budget Control Act of 2011, which, among other things, creates the Joint Select Committee on 
Deficit Reduction to recommend to Congress proposals in spending reductions. The Joint Select Committee did not achieve a targeted deficit 
reduction of an amount greater than $1.2 trillion for the years 2013 through 2021, triggering the legislation’s automatic reduction to several 
government programs. This includes aggregate reductions to Medicare payments to healthcare providers of up to 2.0% per fiscal year, starting in 
2013. In January 2013, President Obama signed into law the American Taxpayer Relief Act of 2012, which, among other things, reduced 
Medicare payments to several categories of healthcare providers and increased the statute of limitations period for the government to recover 
overpayments to providers from three to five years. If we ever obtain regulatory approval and commercialization of ganaxolone, these new laws 
may result in additional reductions in Medicare and other healthcare funding, which could have a material adverse effect on our customers and 
accordingly, our financial operations. Legislative and regulatory proposals have been made to expand post-approval requirements and restrict 
sales and promotional activities for pharmaceutical products. We cannot be sure whether additional legislative changes will be enacted, or whether 
FDA regulations, guidance or interpretations will be changed, or what the impact of such changes on the marketing approvals of ganaxolone may 
be.  

In the United States, the European Union and other potentially significant markets for ganaxolone, government authorities and third-party 
payors are increasingly attempting to limit or regulate the price of medical products and services, particularly for new and innovative products and 
therapies, which has resulted in lower average selling prices. Furthermore, the increased emphasis on managed healthcare in the United States and 
on country and regional pricing and reimbursement controls in the European Union will put additional pressure on product pricing, reimbursement 
and usage, which may adversely affect our future product sales and results of operations. These pressures can arise from rules and practices of 
managed care groups, judicial decisions and governmental laws and regulations related to Medicare, Medicaid and healthcare reform, 
pharmaceutical reimbursement policies and pricing in general.  

Some countries require approval of the sale price of a drug before it can be marketed. In many countries, the pricing review period begins 

after marketing or product licensing approval is granted. In some foreign markets, prescription pharmaceutical pricing remains subject to 
continuing governmental control even after initial approval is granted. As a result, we might obtain marketing approval for ganaxolone in a 
particular country, but then be subject to price regulations that delay our commercial launch of the product, possibly for lengthy time periods, 
which could negatively impact the revenue we are able to generate from the sale of the product in that particular country.  

43  

   
   
   
   
   
   
 
Table of Contents  

Adverse pricing limitations may hinder our ability to recoup our investment in ganaxolone even if ganaxolone obtains marketing approval.  

Laws and regulations governing international operations may preclude us from developing, manufacturing and selling product candidates 
outside of the United States and require us to develop and implement costly compliance programs.  

As we seek to expand our operations outside of the United States, we must comply with numerous laws and regulations in each 
jurisdiction in which we plan to operate. The creation and implementation of international business practices compliance programs is costly and 
such programs are difficult to enforce, particularly where reliance on third parties is required.  

The Foreign Corrupt Practices Act, or FCPA, prohibits any United States individual or business from paying, offering, authorizing 

payment or offering of anything of value, directly or indirectly, to any foreign official, political party or candidate for the purpose of influencing 
any act or decision of the foreign entity in order to assist the individual or business in obtaining or retaining business. The FCPA also obligates 
companies whose securities are listed in the United States to comply with certain accounting provisions requiring such companies to maintain 
books and records that accurately and fairly reflect all transactions of the corporation, including international subsidiaries, and to devise and 
maintain an adequate system of internal accounting controls for international operations. The anti-bribery provisions of the FCPA are enforced 
primarily by the DOJ. The SEC is involved with enforcement of the books and records provisions of the FCPA.  

Compliance with the FCPA is expensive and difficult, particularly in countries in which corruption is a recognized problem. In addition, 

the FCPA presents particular challenges in the pharmaceutical industry, because, in many countries, hospitals are operated by the government, and 
doctors and other hospital employees are considered foreign officials. Certain payments to hospitals in connection with clinical trials and other 
work have been deemed to be improper payments to government officials and have led to FCPA enforcement actions.  

Various laws, regulations and executive orders also restrict the use and dissemination outside of the United States, or the sharing with 
certain foreign nationals, of information classified for national security purposes, as well as certain products and technical data relating to those 
products. Our expanding presence outside of the United States will require us to dedicate additional resources to comply with these laws, and 
these laws may preclude us from developing, manufacturing, or selling ganaxolone outside of the United States, which could limit our growth 
potential and increase our development costs.  

The failure to comply with laws governing international business practices may result in substantial penalties, including suspension or 
debarment from government contracting. Violation of the FCPA can result in significant civil and criminal penalties. Indictment alone under the 
FCPA can lead to suspension of the right to do business with the United States government until the pending claims are resolved. Conviction of a 
violation of the FCPA can result in long-term disqualification as a government contractor. The termination of a government contract or 
relationship as a result of our failure to satisfy any of our obligations under laws governing international business practices would have a negative 
impact on our operations and harm our reputation and ability to procure government contracts. The SEC also may suspend or bar issuers from 
trading securities on United States exchanges for violations of the FCPA’s accounting provisions.  

Our relationships with customers and third-party payors will be subject to applicable anti-kickback, fraud and abuse and other healthcare 
laws and regulations, which could expose us to criminal sanctions, civil penalties, contractual damages, reputational harm and diminished 
profits and future earnings.  

Healthcare providers, physicians and third-party payors will play a primary role in the recommendation and prescription of any product 

candidates for which we obtain marketing approval. Our future arrangements with third-party payors and customers may expose us to broadly 
applicable fraud and abuse and other healthcare laws and regulations that may affect the business or financial arrangements and relationships 
through which we would market, sell and distribute our products. Even though we do not and will not control referrals of healthcare services or 
bill directly to Medicare, Medicaid or other third-party payors, federal and state healthcare laws and regulations pertaining to fraud and abuse and 
patients’ rights are and will be applicable to our business. Restrictions under applicable federal and state healthcare laws and regulations that may 
affect our operations (including our marketing, promotion, educational programs, pricing, and relationships with healthcare providers or other 
entities, among other things) and expose us to areas of risk including the following:  

44  

   
   
   
   
   
   
   
   
   
   
 
Table of Contents  

•                   the federal Anti-Kickback Statute prohibits, among other things, persons from knowingly and willfully soliciting, offering, receiving 
or providing remuneration, directly or indirectly, in cash or in kind, to induce or reward, or in return for, either the referral of an 
individual for, or the purchase, order or recommendation of, any good or service, for which payment may be made under a federal 
healthcare program such as Medicare and Medicaid;  

•                   federal civil and criminal false claims laws and civil monetary penalty laws impose criminal and civil penalties, including through 
civil whistleblower or qui tam actions, against individuals or entities for knowingly presenting, or causing to be presented, to the 
federal government, including the Medicare and Medicaid programs, claims for payment that are false or fraudulent or making a 
false statement to avoid, decrease or conceal an obligation to pay money to the federal government;  

•                   the federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, imposes criminal and civil liability for 

executing a scheme to defraud any healthcare benefit program and also created federal criminal laws that prohibit knowingly and 
willfully falsifying, concealing or covering up a material fact or making any materially false statements in connection with the 
delivery of or payment for healthcare benefits, items or services;  

•                   HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act, or HITECH, also imposes 
obligations, including mandatory contractual terms, with respect to safeguarding the privacy, security and transmission of 
individually identifiable health information;  

•                   the Affordable Care Act requires manufacturers of drugs, devices, biologics and medical supplies that are reimbursable under 

Medicare, Medicaid, or Children’s Health Insurance Program, to report annually to HHS information related to payments and other 
transfers of value to physicians and teaching hospitals, and ownership and investment interests held by physicians and their 
immediate family members and applicable group purchasing organizations; and  

•                   analogous state and foreign laws and regulations, such as state anti-kickback and false claims laws, may apply to sales or marketing 
arrangements and claims involving healthcare items or services reimbursed by non-governmental third-party payors, including 
private insurers; some state laws require pharmaceutical companies to comply with the pharmaceutical industry’s voluntary 
compliance guidelines and the relevant compliance guidance promulgated by the federal government and may require drug 
manufacturers to report information related to payments and other transfers of value to physicians and other healthcare providers or 
marketing expenditures; and state and foreign laws govern the privacy and security of health information in specified circumstances, 
many of which differ from each other in significant ways and often are not preempted by HIPAA, thus complicating compliance 
efforts.  

Efforts to ensure that our business arrangements with third parties are compliant with applicable healthcare laws and regulations will 

involve the expenditure of appropriate, and possibly significant, resources. Nonetheless, it is possible that governmental authorities will conclude 
that our business practices may not comply with current or future statutes, regulations or case law involving applicable fraud and abuse or other 
healthcare laws and regulations. If our operations are found to be in violation of any of these laws or any other governmental regulations that may 
apply to us, we may be subject to significant civil, criminal and administrative penalties, damages, fines, imprisonment, exclusion from 
government funded healthcare programs, such as Medicare and Medicaid, and the curtailment or restructuring of our operations. If any physicians 
or other healthcare providers or entities with whom we expect to do business are found to not be in compliance with applicable laws, they may be 
subject to criminal, civil or administrative sanctions, including exclusions from government funded healthcare programs.  

Risks Related to Our Intellectual Property  

If we are unable to protect our intellectual property rights or if our intellectual property rights are inadequate for our technology and product 
candidates, our competitive position could be harmed.  

Our commercial success will depend in large part on our ability to obtain and maintain patent and other intellectual property protection in 

the United States and other countries with respect to our proprietary technology and products. We rely on trade secret, patent, copyright and 
trademark laws, and confidentiality, licensing and other agreements with employees and third parties, all of which offer only limited protection. 
We seek to protect our  

45  

   
   
   
   
   
   
   
   
   
   
   
 
Table of Contents  

proprietary position by filing and prosecuting patent applications in the United States and abroad related to our novel technologies and products 
that are important to our business.  

The patent positions of biotechnology and pharmaceutical companies generally are highly uncertain, involve complex legal and factual 

questions and have in recent years been the subject of much litigation. As a result, the issuance, scope, validity, enforceability and commercial 
value of our patents, including those patent rights licensed to us by third parties, are highly uncertain. The steps we or our licensors have taken to 
protect our proprietary rights may not be adequate to preclude misappropriation of our proprietary information or infringement of our intellectual 
property rights, both inside and outside the United States. Further, the examination process may require us or our licensors to narrow the claims 
for our pending patent applications, which may limit the scope of patent protection that may be obtained if these applications issue. The rights 
already granted under any of our currently issued patents or those licensed to us and those that may be granted under future issued patents may not 
provide us with the proprietary protection or competitive advantages we are seeking. If we or our licensors are unable to obtain and maintain 
patent protection for our technology and products, or if the scope of the patent protection obtained is not sufficient, our competitors could develop 
and commercialize technology and products similar or superior to ours, and our ability to successfully commercialize our technology and products 
may be adversely affected. It is also possible that we or our licensors will fail to identify patentable aspects of inventions made in the course of our 
development and commercialization activities before it is too late to obtain patent protection on them.  

With respect to patent rights, we do not know whether any of our granted or issued patents will effectively prevent others from 
commercializing competitive technologies and products. Publications of discoveries in the scientific literature often lag behind the actual 
discoveries, and patent applications in the United States and other jurisdictions are typically not published until 18 months after filing or in some 
cases not at all, until they are issued as a patent. Therefore we cannot be certain that we or our licensors were the first to make the inventions 
claimed in our owned or licensed patents or pending patent applications, or that we or our licensors were the first to file for patent protection of 
such inventions.  

Our pending applications cannot be enforced against third parties practicing the technology claimed in such applications unless and until 

a patent issues from such applications. Because the issuance of a patent is not conclusive as to its inventorship, scope, validity or enforceability, 
issued patents that we own or have licensed from third parties may be challenged in the courts or patent offices in the United States and abroad. 
Such challenges may result in the loss of patent protection, the narrowing of claims in such patents or the invalidity or unenforceability of such 
patents, which could limit our ability to stop others from using or commercializing similar or identical technology and products, or limit the 
duration of the patent protection for our technology and products. Protecting against the unauthorized use of our or our licensors’ patented 
technology, trademarks and other intellectual property rights is expensive, difficult and may in some cases not be possible. In some cases, it may 
be difficult or impossible to detect third-party infringement or misappropriation of our intellectual property rights, even in relation to issued patent 
claims, and proving any such infringement may be even more difficult.  

Third parties may initiate legal proceedings alleging that we are infringing their intellectual property rights, the outcome of which would be 
uncertain and could harm our business.  

Our commercial success depends upon our ability to develop, manufacture, market and sell ganaxolone, and to use our related proprietary 

technologies. We may become party to, or threatened with, future adversarial proceedings or litigation regarding intellectual property rights with 
respect to ganaxolone, including interference or derivation proceedings before the United States Patent and Trademark Office, or USPTO. Third 
parties may assert infringement claims against us based on existing patents or patents that may be granted in the future. If we are found to infringe 
a third party’s intellectual property rights, we could be required to obtain a license from such third party to continue commercializing ganaxolone. 
However, we may not be able to obtain any required license on commercially reasonable terms or at all. Under certain circumstances, we could be 
forced, including by court order, to cease commercializing ganaxolone. In addition, in any such proceeding or litigation, we could be found liable 
for monetary damages. A finding of infringement could prevent us from commercializing ganaxolone or force us to cease some of our business 
operations, which could materially harm our business. Any claims by third parties that we have misappropriated their confidential information or 
trade secrets could have a similar negative impact on our business.  

While ganaxolone is in preclinical studies and clinical trials, we believe that the use of ganaxolone in these preclinical studies and clinical 
trials falls within the scope of the exemptions provided by 35 U.S.C. Section 271(e) in the United States, which exempts from patent infringement 
liability activities reasonably related to the  

46  

   
   
   
   
   
   
   
   
 
Table of Contents  

development and submission of information to the FDA. As ganaxolone progresses toward commercialization, the possibility of a patent 
infringement claim against us increases. While ganaxolone itself is off patent, we attempt to ensure that our solid and liquid nanoparticulate 
formulation of ganaxolone and the methods we employ to manufacture ganaxolone do not infringe other parties’ patents and other proprietary 
rights. There can be no assurance they do not, however, and competitors or other parties may assert that we infringe their proprietary rights in any 
event.  

If we breach our license agreement with Purdue Neuroscience Company, it could have a material adverse effect on our commercialization 
efforts for ganaxolone or such other compounds in the United States.  

In September 2004, we entered into a license agreement with Purdue Neuroscience Company, or Purdue, which was most recently 
amended and restated in May 2008, granting us exclusive rights to certain know-how and technology relating thereto, excluding the field of 
treatment of unpleasant sensory or emotional experience associated with actual or potential tissue damage, or described in terms of such damage. 
If we materially breach or fail to perform any provision under this license agreement (including failure to make payments to Purdue when due for 
royalties and other sub-license revenue, failure to cure a breach for failure to use commercially reasonable efforts to develop and commercialize at 
least one licensed product, and commencement of bankruptcy or insolvency proceedings against us) Purdue has the right to terminate our license, 
and upon the effective date of such termination, we must cease all activities licensed all rights, data, information, know-how, and material licensed 
or transferred to us under this license agreement will revert to Purdue and all rights, data, information, know-how, material, records and 
registrations developed or made by us that relate in whole or in part to the activities contemplated by our amended and restated license agreement 
with Purdue will be transferred to Purdue. To the extent such a breach relates to ganaxolone, we would expect to exercise all rights and remedies 
available to us, including attempting to cure any breach by us, and otherwise seek to preserve our rights, but we may not be able to do so in a 
timely manner, at an acceptable cost to us or at all. Any uncured, material breach under the license agreement could result in our loss of rights to 
practice our patent rights and could have a material adverse effect on our commercialization efforts for ganaxolone.  

We may not be able to protect our intellectual property rights throughout the world.  

Filing, prosecuting and defending patents on ganaxolone and any future product candidates throughout the world would be prohibitively 
expensive, and our or our licensors’ intellectual property rights in some countries outside the United States can be less extensive than those in the 
United States. In addition, the laws and practices of some foreign countries do not protect intellectual property rights to the same extent as federal 
and state laws in the United States. Consequently, we may not be able to prevent third parties from practicing our inventions in all countries 
outside the United States, or from selling or importing products made using our inventions into or within the United States or other jurisdictions. 
Competitors may use our technologies in jurisdictions where we have not obtained patent protection to develop their own products, and may 
export otherwise infringing products to territories where we have patent protection, but where enforcement is not as strong as that in the United 
States. These products may compete with our products in jurisdictions where we do not have any issued patents and our patent claims or other 
intellectual property rights may not be effective or sufficient to prevent them from competing with us in these jurisdictions.  

Many companies have encountered significant problems in protecting and defending intellectual property rights in certain foreign 

jurisdictions. The legal systems of certain countries, particularly certain developing countries, do not favor the enforcement of patents and other 
intellectual property protection, particularly those relating to biopharmaceuticals, which could make it difficult for us to stop the infringement of 
our or our licensor’s patents or marketing of competing products in violation of our proprietary rights generally in those countries. Proceedings to 
enforce our patent rights in foreign jurisdictions could result in substantial cost and divert our efforts and attention from other aspects of our 
business, could put our patents at risk of being invalidated or interpreted narrowly and our patent applications at risk of not issuing and could 
provoke third parties to assert claims against us. We may not prevail in any lawsuits that we initiate and the damages or other remedies awarded, if 
any, may not be commercially meaningful.  

The laws of certain foreign countries may not protect our rights to the same extent as the laws of the United States, and these foreign laws 

may also be subject to change. For example, novel formulations and manufacturing processes may not be patentable in certain jurisdictions, and 
the requirements for patentability may differ in certain countries, particularly developing countries. Furthermore, generic drug manufacturers or 
other competitors may challenge the scope, validity or enforceability of our patents, requiring us to engage in complex, lengthy and costly 
litigation or other proceedings. Generic drug manufacturers may develop, seek approval for, and launch generic  

47  

   
   
   
   
   
   
   
   
 
Table of Contents  

versions of our products. Many countries, including European Union countries, India, Japan and China, have compulsory licensing laws under 
which a patent owner may be compelled under certain circumstances to grant licenses to third parties. In those countries, we may have limited 
remedies if patents are infringed or if we are compelled to grant a license to a third party, which could materially diminish the value of our patents. 
This could limit our potential revenue opportunities. Accordingly, our efforts to enforce intellectual property rights around the world may be 
inadequate to obtain a significant commercial advantage from our intellectual property.  

Patent terms may be inadequate to protect our competitive position on our products for an adequate amount of time.  

Given the amount of time required for the development, testing and regulatory review of new product candidates, such as ganaxolone, 

patents protecting such candidates might expire before or shortly after such candidates are commercialized. We expect to seek extensions of patent 
terms in the United States and, if available, in other countries where we are prosecuting patents. In the United States, the Drug Price Competition 
and Patent Term Restoration Act of 1984 permits a patent term extension of up to five years beyond the normal expiration of the patent, which is 
limited to the approved indication (or any additional indications approved during the period of extension). However, the applicable authorities, 
including the FDA and the USPTO in the United States, and any equivalent regulatory authority in other countries, may not agree with our 
assessment of whether such extensions are available, and may refuse to grant extensions to our patents, or may grant more limited extensions than 
we request. If this occurs, our competitors may be able to take advantage of our investment in development and clinical trials by referencing our 
clinical and preclinical data and launch their product earlier than might otherwise be the case.  

Changes in patent laws, including recent patent reform legislation, could increase the uncertainties and costs surrounding the prosecution of 
our patent applications and the enforcement or defense of our issued patents.  

As is the case with other pharmaceutical companies, our success is heavily dependent on intellectual property, particularly patents. 

Obtaining and enforcing patents in the pharmaceutical industry involve technological and legal complexity, and obtaining and enforcing 
pharmaceutical patents is costly, time-consuming, and inherently uncertain. Changes in either the patent laws or interpretation of the patent laws 
in the United States and other countries may diminish the value of our patents or narrow the scope of our patent protection. For example, the 
United States Supreme Court has ruled on several patent cases in recent years, either narrowing the scope of patent protection available in certain 
circumstances or weakening the rights of patent owners in certain situations. In addition to increasing uncertainty with regard to our ability to 
obtain patents in the future, this combination of events has created uncertainty with respect to the value of patents, once obtained. Depending on 
decisions by Congress, the federal courts, and the USPTO, the laws and regulations governing patents could change in unpredictable ways that 
would weaken our ability to obtain new patents or to enforce existing patents and patents we may obtain in the future. Recent patent reform 
legislation could increase the uncertainties and costs surrounding the prosecution of our patent applications and the enforcement or defense of our 
issued patents.  

In September 2011, the Leahy-Smith America Invents Act, or the Leahy-Smith Act, was signed into law. The Leahy-Smith Act includes 

a number of significant changes to United States patent law. These include provisions that affect the way patent applications will be prosecuted 
and may also affect patent litigation. In particular, under the Leahy-Smith Act, the United States transitioned in March 2013 to a “first to file” 
system in which the first inventor to file a patent application will be entitled to the patent. Third parties are allowed to submit prior art before the 
issuance of a patent by the USPTO and may become involved in opposition, derivation, reexamination, inter-parties review or interference 
proceedings challenging our patent rights or the patent rights of our licensors. An adverse determination in any such submission, proceeding or 
litigation could reduce the scope of, or invalidate patent rights, which could adversely affect our competitive position.  

The USPTO is currently developing regulations and procedures to govern administration of the Leahy-Smith Act, and many of the 
substantive changes to patent law associated with the Leahy-Smith Act, and in particular, the first to file provisions, did not become effective until 
March 16, 2013. Accordingly, it is not clear what, if any, impact the Leahy-Smith Act will have on the operation of our business. However, the 
Leahy-Smith Act and its implementation could increase the uncertainties and costs surrounding the prosecution of our patent applications and the 
enforcement or defense of our issued patents.

Obtaining and maintaining our patent protection depends on compliance with various procedural, document submissions, fee payment and 
other requirements imposed by governmental patent agencies, and our patent protection could be reduced or eliminated for non-compliance 
with these requirements.  

Periodic maintenance fees on any issued patent are due to be paid to the USPTO and foreign patent agencies in several stages over the 

lifetime of the patent. The USPTO and various foreign governmental patent agencies require compliance with a number of procedural, 
documentary, fee payment and other similar provisions during the patent application process. While an inadvertent lapse can in many cases be 
cured by payment of a late fee or by other means in accordance with the applicable rules, there are situations in which noncompliance can result in 
abandonment or lapse of the patent or patent application, resulting in partial or complete loss of patent rights in the relevant jurisdiction. Non-
compliance events that could result in abandonment or lapse of a patent or patent application include, but are not limited to, failure to respond to 
official actions within prescribed time limits, non-payment of fees and failure to properly legalize and submit formal documents. If we or our 
licensors fail to maintain the patents and patent applications covering our product candidates, our competitive position would be adversely 
affected.  

We may become involved in lawsuits to protect or enforce our intellectual property, which could be expensive, time consuming and 
unsuccessful and have a material adverse effect on the success of our business.  

Competitors may infringe our patents or misappropriate or otherwise violate our intellectual property rights. To counter infringement or 

unauthorized use, litigation may be necessary in the future to enforce or defend our intellectual property rights, to protect our trade secrets or to 
determine the validity and scope of our own intellectual property rights or the proprietary rights of others. Also, third parties may initiate legal 
proceedings against us to challenge the validity or scope of intellectual property rights we own or control. These proceedings can be expensive 
and time consuming. Many of our current and potential competitors have the ability to dedicate substantially greater resources to defend their 
intellectual property rights than we can. Accordingly, despite our efforts, we may not be able to prevent third parties from infringing upon or 
misappropriating our intellectual property. Litigation could result in substantial costs and diversion of management resources, which could harm 
our business and financial results. In addition, in an infringement proceeding, a court may decide that a patent owned or controlled by us is invalid 
or unenforceable, or may refuse to stop the other party from using the technology at issue on the grounds that our patents do not cover the 
technology in question. An adverse result in any litigation proceeding could put one or more of our patents at risk of being invalidated, held 
unenforceable or interpreted narrowly. Furthermore, because of the substantial amount of discovery required in connection with intellectual 
property litigation, there is a risk that some of our confidential information could be compromised by disclosure during this type of litigation. 
There could also be public announcements of the results of hearings, motions or other interim proceedings or developments. If securities analysts 
or investors perceive these results to be negative, it could have a material adverse effect on the price of shares of our common stock.  

We may be subject to claims by third parties asserting that we have misappropriated their intellectual property, or claiming ownership of what 
we regard as our own intellectual property.  

Some of our employees were previously employed at universities or at other biotechnology or pharmaceutical companies, including our 

competitors or potential competitors. Some of these employees, including each member of our senior management, executed proprietary rights, 
non-disclosure and non-competition agreements, or similar agreements, in connection with such previous employment. Although we try to ensure 
that our employees do not use the proprietary information or know-how of others in their work for us, we may be subject to claims that we or 
these employees have used or disclosed intellectual property, including trade secrets or other proprietary information, of any such third party. 
Litigation may be necessary to defend against such claims. If we fail in defending any such claims, in addition to paying monetary damages, we 
may lose valuable intellectual property rights or personnel or sustain damages. Such intellectual property rights could be awarded to a third party, 
and we could be required to obtain a license from such third party to commercialize our technology or products. Such a license may not be 
available on commercially reasonable terms or at all. Even if we are successful in defending against such claims, litigation could result in 
substantial costs and be a distraction to management.  

Intellectual property rights do not necessarily address all potential threats to our competitive advantage.  

The degree of future protection afforded by our intellectual property rights is uncertain because intellectual property rights have 
limitations, and may not adequately protect our business, or permit us to maintain our competitive advantage. The following examples are 
illustrative:

•                   others may be able to make compounds or ganaxolone formulations that are similar to our ganaxolone formulations but that are not 

covered by the claims of the patents that we own or control;  

•                   we or any strategic partners might not have been the first to make the inventions covered by the issued patents or pending patent 

applications that we own or control;  

•                   we might not have been the first to file patent applications covering certain of our inventions;  

•                   others may independently develop similar or alternative technologies or duplicate any of our technologies without infringing our 

intellectual property rights;  

•                   it is possible that our pending patent applications will not lead to issued patents;  

•                   issued patents that we own or control may not provide us with any competitive advantages, or may be held invalid or unenforceable 

as a result of legal challenges;  

•                   our competitors might conduct research and development activities in the United States and other countries that provide a safe 

harbor from patent infringement claims for certain research and development activities, as well as in countries where we do not have 
patent rights and then use the information learned from such activities to develop competitive products for sale in our major 
commercial markets;  

•                   we may not develop additional proprietary technologies that are patentable; and  

•                   the patents of others may have an adverse effect on our business.  

Risks Related to Employee Matters, Managing Growth and Becoming a Public Company  

Our future success depends on our ability to retain our executive officers and to attract, retain and motivate qualified personnel.  

We are highly dependent upon Christopher M. Cashman, our Chief Executive Officer, Edward F. Smith, our Chief Financial Officer, 
Albena I. Patroneva, M.D., our Chief Medical Officer and Gail M. Farfel, Ph.D., our Chief Clinical Development and Regulatory Officer. The 
employment agreements we have with the persons named above do not prevent such persons from terminating their employment with us at any 
time. We do not maintain “key person” insurance for any of our executives or other employees. The loss of the services of any of these persons 
could impede the achievement of our research, development and commercialization objectives.  

We will need to grow the size of our organization, and we may experience difficulties in managing this growth.  

As of December 31, 2014, we had nine full-time employees. As our development and commercialization plans and strategies develop, or 
as a result of any future acquisitions, we will need additional managerial, operational, sales, marketing, financial and other resources. In addition, 
it may become more cost effective to bring in house certain resources currently outsourced to consultants and other third-parties. Our 
management, personnel and systems currently in place may not be adequate to support our future growth. Future growth would impose significant 
added responsibilities on members of management, including:  

•                   managing our clinical trials effectively;  

•                   identifying, recruiting, maintaining, motivating and integrating additional employees;  

•                   managing our internal development efforts effectively while complying with our contractual obligations to licensors, licensees, 

contractors and other third parties;  

•                   improving our managerial, development, operational and finance systems; and  

•                   expanding our facilities.  

As our operations expand, we will need to manage additional relationships with various strategic partners, suppliers and other third 

parties. Our future financial performance and our ability to commercialize ganaxolone, if

approved, and to compete effectively will depend, in part, on our ability to manage any future growth effectively. To that end, we must be able to 
manage our development efforts and clinical trials effectively and hire, train and integrate additional management, administrative and sales and 
marketing personnel. Our failure to accomplish any of these tasks could prevent us from successfully growing our company.  

If we are unable to attract and retain highly qualified employees, and other personnel, advisors and consultants with scientific, technical and 
managerial expertise, we may not be able to grow effectively.  

Our future growth and success depend on our ability to recruit, retain, manage and motivate our employees, consultants and other third-

parties. The loss of any member of our senior management team or the inability to hire or retain experienced management personnel could 
compromise our ability to execute our business plan and harm our operating results.  

Because of the specialized scientific and managerial nature of our business, we rely heavily on our ability to attract and retain qualified 

scientific, technical and managerial personnel, advisors and consultants. The competition for qualified personnel in the pharmaceutical field is 
significant and, as a result, we may be unable to continue to attract and retain qualified personnel necessary for the development of our business.  

We may acquire other assets or businesses, or form collaborations or make investments in other companies or technologies that could harm 
our operating results, dilute our stockholders’ ownership, increase our debt or cause us to incur significant expense.  

As part of our business strategy, we may pursue acquisitions of assets, including preclinical, clinical or commercial stage products or 

product candidates, or businesses, or strategic alliances and collaborations, to expand our existing technologies and operations. We may not 
identify or complete these transactions in a timely manner, on a cost-effective basis, or at all, and we may not realize the anticipated benefits of 
any such transaction, any of which could have a detrimental effect on our financial condition, results of operations and cash flows. We have no 
experience with acquiring other companies, products or product candidates, and limited experience with forming strategic alliances and 
collaborations. We may not be able to find suitable acquisition candidates, and if we make any acquisitions, we may not be able to integrate these 
acquisitions successfully into our existing business and we may incur additional debt or assume unknown or contingent liabilities in connection 
therewith. Integration of an acquired company or assets may also disrupt ongoing operations, require the hiring of additional personnel and the 
implementation of additional internal systems and infrastructure, especially the acquisition of commercial assets, and require management 
resources that would otherwise focus on developing our existing business. We may not be able to find suitable strategic alliance or collaboration 
partners or identify other investment opportunities, and we may experience losses related to any such investments.  

To finance any acquisitions or collaborations, we may choose to issue debt or equity securities as consideration. Any such issuance of 
shares would dilute the ownership of our stockholders. If the price of our common stock is low or volatile, we may not be able to acquire other 
assets or companies or fund a transaction using our stock as consideration. Alternatively, it may be necessary for us to raise additional funds for 
acquisitions through public or private financings. Additional funds may not be available on terms that are favorable to us, or at all.  

Our employees may engage in misconduct or other improper activities, including noncompliance with regulatory standards and requirements, 
which could cause significant liability for us and harm our reputation.  

We are exposed to the risk of employee fraud or other misconduct, including intentional failures to comply with FDA regulations or 

similar regulations of comparable foreign regulatory authorities, provide accurate information to the FDA or comparable foreign regulatory 
authorities, comply with manufacturing standards we have established, comply with federal and state healthcare fraud and abuse laws and 
regulations and similar laws and regulations established and enforced by comparable foreign regulatory authorities, report financial information or 
data accurately or disclose unauthorized activities to us. Employee misconduct could also involve the improper use of information obtained in the 
course of clinical trials, which could result in regulatory sanctions and serious harm to our reputation. We have adopted a code of conduct for our 
directors, officers and employees, or the Code of Conduct, but it is not always possible to identify and deter employee misconduct, and the 
precautions we take to detect and prevent this activity may not be effective in controlling unknown or unmanaged risks or losses or in protecting 
us from governmental investigations or other actions or lawsuits stemming from a failure to be in compliance with such laws or regulations. If any 
such actions are instituted against us, and we are not successful in defending ourselves or asserting our rights, those actions could have a 
significant impact on our business and results of operations, including the imposition of significant fines or other sanctions.

Risks Related to Ownership of Our Common Stock  

We do not know whether an active, liquid and orderly trading market will develop for our common stock and as a result it may be difficult for 
you to sell your shares of our common stock.  

Although we are listed on The NASDAQ Global Market, an active trading market for our shares may never develop or be sustained.  The 
market value of our common stock may decrease. The lack of an active market may impair your ability to sell your shares at the time you wish to 
sell them or at a price that you consider reasonable. The lack of an active market may also reduce the fair market value of your shares. Further, an 
inactive market may also impair our ability to raise capital by selling shares of our common stock and may impair our ability to enter into 
collaborations or acquire companies or products by using our shares of common stock as consideration.  

The market price of our stock may be volatile, and you could lose all or part of your investment.  

The trading price of our common stock is likely to be highly volatile and could be subject to wide fluctuations in response to various 

factors, some of which are beyond our control. In addition to the factors discussed in this “Risk Factors” section, these factors include:  

•                   the success of competitive products or technologies;  

•                   regulatory actions with respect to our products or our competitors’ products;  

•                   actual or anticipated changes in our growth rate relative to our competitors;  

•                   announcements by us or our competitors of significant acquisitions, strategic partnerships, joint ventures, collaborations or capital 

commitments;  

•                   results of clinical trials of ganaxolone or product candidates of our competitors;  

•                   regulatory or legal developments in the United States and other countries;  

•                   developments or disputes concerning patent applications, issued patents or other proprietary rights;  

•                   the recruitment or departure of key personnel;  

•                   the level of expenses related to our clinical development programs;  

•                   the results of our efforts to in-license or acquire additional product candidates or products;  

•                   actual or anticipated changes in estimates as to financial results, development timelines or recommendations by securities analysts;  

•                   variations in our financial results or those of companies that are perceived to be similar to us;  

•                   fluctuations in the valuation of companies perceived by investors to be comparable to us;  

•                   share price and volume fluctuations attributable to inconsistent trading volume levels of our shares;  

•                   announcement or expectation of additional financing efforts;  

•                   sales of our common stock by us, our insiders or our other stockholders;  

•                   changes in the structure of healthcare payment systems;  

•                   market conditions in the pharmaceutical and biotechnology sectors;  

•                   general economic, industry and market conditions; and  

•                   other events or factors, many of which are beyond our control.

In addition, the stock market in general, The NASDAQ Global Market and pharmaceutical and biotechnology companies in particular, 

have experienced extreme price and volume fluctuations that have often been unrelated or disproportionate to the operating performance of these 
companies. Broad market and industry factors may negatively affect the market price of our common stock, regardless of our actual operating 
performance. The realization of any of these risks or any of a broad range of other risks, including those described in these “Risk Factors,” could 
have a dramatic and material adverse impact on the market price of our common stock.  

We may be subject to securities litigation, which is expensive and could divert our management’s attention.  

The market price of our common stock may be volatile, and in the past companies that have experienced volatility in the market price of 

their stock have been subject to securities class action litigation. We may be the target of this type of litigation in the future. Securities litigation 
against us could result in substantial costs and divert our management’s attention from other business concerns, which could seriously harm our 
business.  

Insiders have substantial influence over us and could delay or prevent a change in corporate control.  

We estimate that our executive officers, directors, and holders of 5% or more of our capital stock collectively beneficially own 

approximately 82% of our voting stock.  This concentration of ownership could harm the market price of our common stock by:  

•                   delaying, deferring or preventing a change in control of our company;  

•                   impeding a merger, consolidation, takeover or other business combination involving our company; or  

•                   discouraging a potential acquirer from making a tender offer or otherwise attempting to obtain control of our company.  

The interests of this group of stockholders may not always coincide with your interests or the interests of other stockholders and they 

may act in a manner that advances their best interests and not necessarily those of other stockholders, including seeking a premium value for their 
common stock, and might negatively affect the prevailing market price for our common stock.  

We are an “emerging growth company” and we intend to take advantage of reduced disclosure and governance requirements applicable to 
emerging growth companies, which could result in our common stock being less attractive to investors.  

We are an emerging growth company, as defined in the Jumpstart Our Business Startups Act of 2012, or the JOBS Act. For as long as we 

continue to be an emerging growth company, we may take advantage of exemptions from various reporting requirements that are applicable to 
other public companies that are not emerging growth companies, including not being required to comply with the auditor attestation requirements 
of Section 404 of the Sarbanes-Oxley Act of 2002, or the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation 
in our periodic reports and proxy statements, and exemptions from the requirements of holding nonbinding advisory votes on executive 
compensation and stockholder approval of any golden parachute payments not previously approved. We could be an emerging growth company 
for up to five years following the year in which we completed our initial public offering, although circumstances could cause us to lose that status 
earlier, including if the market value of our common stock held by non-affiliates exceeds $700.0 million as of any June 30 before that time or if 
we have total annual gross revenue of $1.0 billion or more during any fiscal year before that time, in which cases we would no longer be an 
emerging growth company as of the following December 31.  If we issue more than $1.0 billion in non-convertible debt during any three-year 
period before that time, we would cease to be an emerging growth company immediately. Even after we no longer qualify as an emerging growth 
company, we may still qualify as a “smaller reporting company” which would allow us to take advantage of many of the same exemptions from 
disclosure requirements including not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley 
Act and reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements. We cannot predict if 
investors will find our common stock less attractive because we may rely on these exemptions. If some investors find our common stock less 
attractive as a result, there may be a less active trading market for our common stock and our stock price may be more volatile.  

Under the JOBS Act, emerging growth companies can also delay adopting new or revised accounting standards until such time as those 

standards apply to private companies. We have irrevocably elected not to avail  

53  

   
   
   
   
   
   
   
   
   
   
   
   
   
 
Table of Contents  

ourselves of this exemption from new or revised accounting standards and, therefore, will be subject to the same new or revised accounting 
standards as other public companies that are not emerging growth companies. As a result, changes in rules of United States generally accepted 
accounting principles or their interpretation, the adoption of new guidance or the application of existing guidance to changes in our business could 
significantly affect our financial position and results of operations.  

We will incur increased costs as a result of operating as a public company, and our management will be required to devote substantial time to 
new compliance initiatives.  

Now that we are a public company, we are incurring significant legal, accounting and other expenses that we did not incur as a private 

company, and these expenses may increase even more after we are no longer an “emerging growth company.” We are subject to the reporting 
requirements of the Exchange Act, the Sarbanes-Oxley Act, the Dodd-Frank Wall Street Reform and Protection Act, as well as rules adopted, and 
to be adopted, by the SEC and NASDAQ Stock Market. Our management and other personnel need to devote a substantial amount of time to these 
compliance initiatives. Moreover, we expect these rules and regulations to substantially increase our legal and financial compliance costs and to 
make some activities more time-consuming and costly. We estimate that we will incur approximately $1.0 million to $2.0 million in incremental 
costs per year associated with being a publicly traded company, although it is possible that our actual incremental costs will be higher than we 
currently estimate. The increased costs will increase our net loss. For example, we expect these rules and regulations to make it more difficult and 
more expensive for us to obtain director and officer liability insurance and we may be required to incur substantial costs to maintain sufficient 
coverage. We cannot predict or estimate the amount or timing of additional costs we may incur to respond to these requirements. The impact of 
these requirements could also make it more difficult for us to attract and retain qualified persons to serve on our board of directors, our board 
committees or as executive officers.  

Because we do not anticipate paying any cash dividends on our capital stock in the foreseeable future, capital appreciation, if any, will be your 
sole source of gain.  

We have never declared or paid cash dividends on our capital stock. We currently intend to retain all of our future earnings, if any, to 

finance the growth and development of our business. In addition, our ability to pay cash dividends is prohibited by our credit facility with Square 
1 Bank, entered into in April 2014 and amended in December 2014, and the terms of any future debt agreements may also preclude us from 
paying dividends. As a result, capital appreciation, if any, of our common stock will be your sole source of gain for the foreseeable future.  

Sales of a substantial number of shares of our common stock in the public market could cause our stock price to fall.  

If our stockholders sell, or indicate an intention to sell, substantial amounts of our common stock in the public market after the lock-up 
and other legal restrictions on resale lapse, the trading price of our common stock could decline. As of December 31, 2014, we had outstanding a 
total of 14,007,754 shares of common stock.  In addition, shares of common stock that are either subject to outstanding options or reserved for 
future issuance under our employee benefit plans will become eligible for sale in the public market to the extent permitted by the provisions of 
various vesting schedules, the lock-up agreements and Rule 144 and Rule 701 under the Securities Act. If these additional shares of common stock 
are sold, or if it is perceived that they will be sold, in the public market, the trading price of our common stock could decline.  

Future sales and issuances of our common stock or rights to purchase common stock, including pursuant to our equity incentive plans, could 
result in additional dilution of the percentage ownership of our stockholders and could cause our stock price to fall.  

We expect that significant additional capital will be needed in the future to continue our planned operations. To raise capital, we may sell 
substantial amounts of common stock or securities convertible into or exchangeable for common stock. These future issuances of equity or equity-
linked securities, together with the exercise of stock options, warrants outstanding or granted in the future and any additional shares issued in 
connection with acquisitions, if any, may result in material dilution to our investors. Such sales may also result in material dilution to our 
stockholders, and new investors could gain rights, preferences and privileges senior to those of holders of our common stock.  

Pursuant to our equity incentive plans, our compensation committee is authorized to grant equity-based incentive awards to our directors, 

executive officers and other employees and service providers. The number of  

54  

   
   
   
   
   
   
   
   
   
   
   
 
Table of Contents  

shares of our common stock available for future grant under our 2005 Stock Option and Incentive Plan, as amended, and our 2014 Equity 
Incentive Plan was zero as of December 31, 2014. In accordance with our 2014 Equity Incentive Plan, on January 1, 2015, 560,310 shares of 
common stock became available for future grant under the plan.  Future equity incentive grants and issuances of common stock under our equity 
incentive plans may have an adverse effect on the market price of our common stock.  

We have broad discretion in the use of our cash reserves and may not use them effectively.  

Our management has broad discretion over the management of our operations and cash resources and could deploy our resources in ways 

that do not improve our business, including our ganaxolone clinical development programs, or enhance the value of our common stock. The 
failure by our management to apply these funds effectively could result in financial losses that could have a material adverse effect on our 
business, cause the market price of our common stock to decline and delay the development of ganaxolone.  

Some provisions of our charter documents and Delaware law may have anti-takeover effects that could discourage an acquisition of us by 
others, even if an acquisition would be beneficial to our stockholders and may prevent attempts by our stockholders to replace or remove our 
current management.  

Provisions in our amended and restated certificate of incorporation and amended and restated bylaws, as well as provisions of Delaware 

law, could make it more difficult for a third party to acquire us or increase the cost of acquiring us, even if doing so would benefit our 
stockholders, or remove our current management. These include provisions that:  

•                   permit our board of directors to issue up to 25,000,000 shares of preferred stock, with any rights, preferences and privileges as it 

may designate;  

•                   provide that all vacancies on our board of directors, including as a result of newly created directorships, may, except as otherwise 

required by law, be filled by the affirmative vote of a majority of directors then in office, even if less than a quorum;  

•                   establish a classified board of directors such that only one of three classes of directors is elected each year;  

•                   provide that directors can only be removed for cause;  

•                   require that any action to be taken by our stockholders must be effected at a duly called annual or special meeting of stockholders 

and not be taken by written consent;  

•                   provide that stockholders seeking to present proposals before a meeting of stockholders or to nominate candidates for election as 
directors at a meeting of stockholders must provide advance notice in writing, and also specify requirements as to the form and 
content of a stockholder’s notice;  

•                   not provide for cumulative voting rights, thereby allowing the holders of a majority of the shares of common stock entitled to vote 

in any election of directors to elect all of the directors standing for election; and  

•                   provide that special meetings of our stockholders may be called only by the chairperson of the board of directors, the chief executive 

officer or the board of directors.  

These provisions may frustrate or prevent any attempts by our stockholders to replace or remove our current management by making it 

more difficult for stockholders to replace members of our board of directors, who are responsible for appointing the members of our management. 
Because we are incorporated in Delaware, we are governed by the provisions of Section 203 of the Delaware General Corporation Law, which 
may discourage, delay or prevent someone from acquiring us or merging with us whether or not it is desired by or beneficial to our stockholders. 
Under Delaware law, a corporation may not, in general, engage in a business combination with any holder of 15.0% or more of its capital stock 
unless the holder has held the stock for three years or, among other things, the board of directors has approved the transaction. Any provision of 
our amended and restated certificate of incorporation or amended and restated bylaws or Delaware law that has the effect of delaying or deterring 
a change in control could limit the opportunity for our stockholders to receive a premium for their shares of our common stock, and could also 
affect the price that some investors are willing to pay for our common stock.

Use of Proceeds  

Our initial public offering of common stock was effected pursuant to a registration statement on Form S-1 (File No 333-195895) that was 

declared effective by the SEC on July 31, 2014, pursuant to which we registered the offering and sale of 6,468,750 shares of common stock, 
$0.001 par value per share (including 843,750 shares available to the underwriters’ for exercise of an option to purchase additional shares, of 
which 133,000 was exercised in September 2014) at a public offering price of $8.00 per share for an aggregate public offering price of $46.1 
million.  Stifel, Nicolaus & Company, Incorporated and JMP Securities LLC acted as joint book-running managers for the initial public offering.  
Oppenheimer & Co. acted as lead manager and Janney Montgomery Scott acted as co-manager for the initial public offering.  

As a result of the initial public offering, we received net proceeds of approximately $41.2 million during the third quarter of 2014 from the 

sale of 5,758,000 shares of common stock, after deducting underwriting discounts, commissions and estimated offering expenses borne by us.  
None of such payments were direct or indirect payments to any of (i) our directors or officers or their associates, (ii) persons owning 10 percent or 
more of our common stock, or (iii) our affiliates.  

There has been no material change in the planned use of proceeds from our initial public offering from that described in the final prospectus 

related to the offering, which we filed with the SEC on August 1, 2014.  As of December 31, 2014, we have used approximately $2.5 million of 
the funds received from our initial public offering (IPO) for clinical trials and payments to research and development consultants

Item 7. Management’s Discussion and Analysis of Finan cial Condition and Results of Operations.  

You should read the following discussion and analysis of our financial condition and results of operations together with our financial 

statements and the related notes appearing at the end of this Annual Report on Form 10-K. Some of the information contained in this discussion 
and analysis or set forth elsewhere in this Annual Report on Form 10-K, including information with respect to our plans and strategy for our 
business and related financing, includes forward-looking statements that involve risks and uncertainties. You should read “Cautionary Note 
Regarding Forward-Looking Statements” and Item 1A. Risk Factors of this Annual Report on Form 10-K for a discussion of important factors 
that could cause actual results to differ materially from the results described in or implied by the forward-looking statements contained in the 
following discussion and analysis .  

Overview  

A 

We are a clinical stage biopharmaceutical company focused on developing and commercializing innovative neuropsychiatric 
therapeutics. Our clinical stage product candidate, ganaxolone, is a small molecule that is a synthetic analog of allopregnanolone, an endogenous 
neurosteroid produced in the central nervous system and known for its anticonvulsive and antianxiety activity. By targeting the same spectrum of 
GABA 
 receptors as endogenous allopregnanolone, ganaxolone delivers its therapeutic benefit through a natural mechanism that we believe may 
offer safety and efficacy advantages compared to other marketed antiepileptic medications. Ganaxolone was rationally designed to unlock the 
receptor. We have a dual strategy of evaluating ganaxolone for 
potential for chronic neurosteriod therapy through modulation of the GABA 
treating seizure disorders, and treating targeted orphan diseases for which there are no approved therapies, the development timelines may be 
abbreviated, and for which there is a strong mechanistic rationale for ganaxolone to offer therapeutic benefit to patients with very high unmet 
needs.  Our orally administered solid and liquid suspension dose forms are being evaluated in our ongoing clinical trials and we are conducting the 
requisite preclinical experiments to ready our intravenous, or IV, dose form for clinical use.  

A   

Our lead indication for ganaxolone is as an adjunctive, or add-on, therapy for the treatment of partial, also known as focal, onset seizures 
in adults with epilepsy. We have completed a Phase 2 clinical trial in 147 patients with focal onset seizures demonstrating that patients who added 
ganaxolone to their medication regimen experienced a statistically significant reduction in seizures as compared to patients who added placebo. 
We are currently enrolling patients in a multinational, randomized, placebo-controlled, Phase 3 clinical trial to evaluate ganaxolone as adjunctive 
treatment of partial-onset seizures in in adult subjects. We believe ganaxolone also has potential in a broad range of neuropsychiatric disorders, 
including orphan indications. We have generated proof-of-concept data for ganaxolone in the treatment of refractory pediatric seizures and as 
monotherapy for adult refractory focal onset seizures. We currently have a Phase 2 proof-of-concept clinical study on-going with ganaxolone for 
the treatment of PCDH19 female pediatric epilepsy and a Phase 2 proof-of-concept investigator sponsored clinical trial evaluating ganaxolone as a 
treatment for behaviors in Fragile X Syndrome. Both PCDH19 female pediatric epilepsy and Fragile X Syndrome are potential orphan disorders 
that have been related to mutations affecting neurosteroid signaling at extrasynaptic GABA 

 receptors.  

A 

Our operations to date have consisted primarily of organizing and staffing our company, developing ganaxolone, including conducting 

preclinical testing and clinical trials, and raising capital. We have funded our operations primarily through sales of equity and debt securities. 
From inception through December 31, 2014, we have received net proceeds of $110.4 million from the issuance of preferred stock, common stock 
and convertible notes payable. At December 31, 2014, we had cash and cash equivalents of $49.7 million.  In connection with our initial public 
offering, which closed during the third quarter of 2014, we received net proceeds of $41.2 million from the sale of 5,758,000 shares of our 
common stock.  We have no products currently available for sale and substantially all of our revenue to date has been derived from research 
grants. We have incurred operating losses since inception, have not generated any product sales revenue and have not achieved profitable 
operations. We incurred net losses of $10.8 million for the year ended December 31, 2014.  Our accumulated deficit as of December 31, 2014 was 
$72.3 million, and we expect to continue to incur substantial losses in future periods. We anticipate that our operating expenses will increase 
substantially as we continue to advance our clinical-stage product candidate, ganaxolone.  

We anticipate that our expenses will increase substantially as we:  

•                   increase the targeted enrollment and add enrollment sites and geographies for our ongoing Phase 3 clinical trial for adjunctive treatment 

of ganaxolone in adult patients with refractory partial onset epileptic seizures;  

•                   conduct clinical proof-of-concept clinical trials in targeted pediatric rare disease indications, including  

58  

   
   
   
   
   
   
   
   
   
   
 
Table of Contents  

PCDH19 and FXS;  

•                   continue the research, development and scale-up manufacturing capabilities to commercialize products and dose forms for which we 

may obtain regulatory approval;  

•                   maintain, expand and protect our global intellectual property portfolio;  

•                   hire additional clinical, manufacturing, and scientific personnel; and  

•                   add operational, financial and management information systems and personnel, including personnel to support our drug development 

and potential future commercialization efforts.  

In addition, we have incurred and will continue to incur significant expenses as a result of becoming a public company, which subjects us to 

the reporting requirements of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), the Sarbanes-Oxley Act of 2002 and the 
rules and regulations of The NASDAQ Global Market. Pursuant to Section 404 of the Sarbanes-Oxley Act of 2002, or Section 404, we will be 
required to furnish a report by our management on our internal control over financial reporting. Commencing with our fiscal year ending 
December 31, 2015, we must perform system and process evaluation and testing of our internal control over financial reporting to allow 
management to report on the effectiveness of our internal control over financial reporting in our Form 10-K filing for that year, as required by 
Section 404.  

We believe that our cash and cash equivalents as of December 31, 2014 will enable us to fund our operating expenses and capital 

expenditure requirements into the second half of 2016. However, we will need to secure additional funding in the future, from one or more equity 
or debt financings, collaborations, or other sources, in order to carry out all of our planned research and development activities with respect to 
ganaxolone.  

Financial Overview  

Research and Development Expenses  

Our research and development expenses consist primarily of costs incurred for the development of ganaxolone, which include:  

•                   employee-related expenses, including salaries, benefits, travel and stock-based compensation expense;  

•                   expenses incurred under agreements with Clinical Research Organizations, or CROs, and investigative sites that conduct our clinical 

trials and preclinical studies;  

•                   the cost of acquiring, developing and manufacturing clinical trial materials;  

•                   facilities, depreciation and other expenses, which include direct and allocated expenses for rent and maintenance of facilities, 

insurance and other supplies; and  

•                   costs associated with preclinical activities and regulatory operations.  

We expense research and development costs when we incur them. We record costs for some development activities, such as clinical 
trials, based on an evaluation of the progress to completion of specific tasks using data such as subject enrollment, clinical site activations or 
information our vendors provide to us.  

We will incur substantial costs beyond our present and planned clinical trials in order to file an NDA and Supplemental New Drug 

Applications, or sNDAs, for ganaxolone in patients with focal onset seizures, PCDH19, FXS and other target indications, and in each case, the 
nature, design, size and cost of further studies and trials will depend in large part on the outcome of preceding studies and trials and discussions 
with regulators. It is difficult to determine with certainty the costs and duration of our current or future clinical trials and preclinical studies, or if, 
when or to what extent we will generate revenue from the commercialization and sale of ganaxolone if we obtain regulatory approval. We may 
never succeed in achieving regulatory approval for ganaxolone. The duration, costs and timing of clinical trials and development of ganaxolone 
will depend on a variety of factors, including the uncertainties of future clinical trials and preclinical studies, uncertainties in clinical trial 
enrollment rate and significant and changing government regulation.

Table of Contents  

In addition, the probability of success for ganaxolone will depend on numerous factors, including competition, manufacturing capability 

and commercial viability. See “Risk Factors.” Our commercial success depends upon attaining significant market acceptance of ganaxolone, if 
approved, among physicians, patients, healthcare payors and the medical community. We will determine which programs to pursue and how much 
to fund each program in response to the scientific and clinical success of ganaxolone, as well as an assessment of ganaxolone’s commercial 
potential.  

General and Administrative Expenses  

General and administrative expenses consist principally of salaries and related costs for executive and other administrative personnel and 

consultants, including stock-based compensation and travel expenses. Other general and administrative expenses include professional fees for 
legal, patent review, consulting and accounting services. General and administrative expenses are expensed when incurred.  

We expect that our general and administrative expenses will increase in the future as a result of new management and employee hiring 
and our scaling operations commensurate with supporting more advanced clinical trials and public company infrastructure. These increases will 
likely include increased costs for insurance, hiring of additional personnel, outside consultants, investor relations, legal counsel and accountants, 
among other expenses.  

Change in Fair Value of Warrant Liability  

Our warrants to purchase our preferred stock were classified as warrant liability and recorded at fair value. This warrant liability was 
subject to re-measurement at each balance sheet date and we recognized any change in fair value in our statements of operations as a change in 
fair value of the derivative liability.  These warrants expired upon our initial public offering and, as a result, the fair value of the warrants was 
reduced to zero as of December 31, 2014.  

Interest Income  

Interest income consists principally of interest income earned on cash and cash equivalent balances.  

Interest Expense  

Interest expense is primarily attributable to interest expense associated with our previously outstanding convertible notes and our credit 

facility entered into in April 2014, and amended in December 2014.  

Cumulative Preferred Stock Dividends  

Cumulative preferred stock dividends represented dividends payable upon a liquidation or deemed liquidation in connection with our 

Series B and C convertible preferred stock.  We are no longer recording preferred stock dividends effective upon the closing of our initial public 
offering, which occurred during the third quarter of 2014.  

Results of Operations  

Research and Development Expenses  

Research and development expenses increased $4.5 million, to $8.7 million, for the year ended December 31, 2014, compared to the 

same period of 2013. The increase resulted primarily from an increase in clinical costs related to our ongoing clinical trial of ganaxolone in 
patients with focal onset seizures that commenced at the end of 2013.  Substantially all research and development expenses relate to our clinical 
trial in focal onset epileptic seizures.  

General and Administrative Expenses  

General and administrative expenses increased $2.0 million, to $3.2 million, for the year ended December 31, 2014, compared to the 
same period of 2013. The increase in general and administrative expenses was primarily due to the hiring of new management and the upward 
scaling of our operations in connection with both our new public company status and ongoing clinical trial of ganaxolone in patients with focal 
onset seizures that commenced during 2013.

Change in Fair Value of Warrant Liability  

We recorded changes in the fair value of our warrant liability which resulted in a gain of $1.2 million and $0.2 million for the years 

ended December 31, 2014 and 2013, respectively. We reduced the value of the liability to zero in connection with the closing of our initial public 
offering in the third quarter of 2014 as the warrants expired unexercised.  

Cumulative Preferred Stock Dividends  

Cumulative preferred stock dividends decreased $1.3 million, to $2.5 million, for the year ended December 31, 2014, compared to the 

same period of 2013. Upon conversion of all outstanding convertible preferred stock in connection with our initial public offering, all cumulative 
preferred stock dividends were canceled.  

Liquidity and Capital Resources  

Since inception, we have incurred net losses and negative cash flows from our operations. We incurred net losses of $10.8 million and 
$5.3 million for the years ended December 31, 2014 and 2013, respectively.  Our cash used in operating activities was $8.6 million for the year 
ended December 31, 2014 compared to $6.6 million for the same period a year ago.  Historically, we have financed our operations principally 
through the sale of common stock, preferred stock and convertible debt. From inception through December 31, 2014, we have received net 
proceeds of $110.4 million from the issuance of preferred stock, common stock and convertible notes payable. At December 31, 2014, we had 
cash and cash equivalents of $49.7 million.  

During the third quarter of 2014, we completed our initial public offering.  In connection with the initial public offering, we sold a total 

of 5,758,000 shares of common stock and received aggregate net proceeds, after underwriting discounts and commissions and other estimated 
offering expenses, of approximately $41.2 million, and all of our outstanding shares of convertible preferred stock converted into shares of 
common stock.  

Square 1 Credit Facility  

In April 2014, we borrowed $2.0 million in connection with a term loan pursuant to a Loan and Security Agreement (LSA) we entered 

into with Square 1 Bank (Square 1).  Pursuant to the terms of the LSA, we made monthly interest-only payments for outstanding borrowings at an 
interest rate equal to the greater of (a) prime plus 2.25% or (b) 5.5% until the LSA was amended in December 2014.  

In December 2014, we entered into a First Amendment to Loan and Security Agreement (Amended LSA) with Square 1.  The Amended 

LSA increased the total term loan availability from $2.0 million to $12.0 million, available in four tranches (in thousands):

availability end dates of Tranches C and D are September 1, 2015 and March 31, 2016, respectively.  

As of December 31, 2014, our outstanding term loan balance of $7.0 million was classified as long-term debt on our balance sheet.  In 

connection with the execution of both the LSA and Amended LSA, we paid debt costs to the financial institution of $25 thousand, which are being 
amortized into interest expense over the remaining term of the loans.  Interest expense related to the loans was $117 thousand for the year ended 
December 31, 2014.  As of December 31, 2014, we had accrued interest of $39 thousand.  There are no financial covenants associated with these 
term loans.  As of December 31, 2014, we were in compliance with all non-financial covenants.

Cash Flows  

Operating Activities.   Cash used in operating activities increased to $8.6 million for the year ended December 31, 2014 compared to 

$6.6 million for the same period a year ago. The increase was driven primarily by an increase in our net loss of $5.6 million and an increase in our 
noncash gain on our warrant liability of $1.0 million.  This was partially offset by net decreases in operating assets and increases in operating 
liabilities of $4.3 million, and increases in stock-based compensation expense of $0.5 million.  The net decreases in operating assets and increases 
in operating liabilities for the year ended December 31, 2014 compared to the same period a year ago are primarily due to $1.7 million in prepaid 
clinical trial expenses from 2013 being expensed throughout 2014, as well as additional accrued clinical trial expenses of $0.7 million as of 
December 31, 2014.  

Investing Activities.   Cash used in investing activities for the purchase of property and equipment was less than $0.1 million for the years 

ended December 31, 2014 and 2013.  

Financing Activities.   Cash provided by financing activities increased to $48.3 million for the year ended December 31, 2014 compared 

to $8.0 million for the same period a year ago.  The increase is primarily attributable to $41.2 million of net proceeds received in 2014 from the 
closing of our initial public offering and $7.0 million received in 2014 related to our credit facility with Square 1 Bank, offset by $7.5 million 
received in 2013 related to the issuance of Series C Preferred Stock.  

Funding Requirements  

We have not achieved profitability since our inception, and we expect to continue to incur net losses for the foreseeable future. We 

expect our cash expenditures to increase in the near term as we fund our planned clinical trials for ganaxolone. We will incur significant legal, 
accounting and other expenses associated with being a public company that we were not required to incur as a private company. In addition, 
Section 404, as well as rules adopted by the SEC and The NASDAQ Stock Market, require public companies to implement specified corporate 
governance practices that were previously inapplicable to us as a private company. We expect these rules and regulations will increase our legal 
and financial compliance costs and will make some activities more time-consuming and costly.  

We believe that our cash and cash equivalents as of December 31, 2014, will enable us to fund our operating expenses and capital 

expenditure requirements into the second half of 2016. However, we will need to raise substantial additional financing in the future to fund our 
operations. In order to meet these additional cash requirements, we may seek to sell additional equity or convertible debt securities that may result 
in dilution to our stockholders. If we raise additional funds through the issuance of convertible debt securities, these securities could have rights 
senior to those of our common stock and could contain covenants that restrict our operations. There can be no assurance that we will be able to 
obtain additional equity or debt financing on terms acceptable to us, if at all. Our failure to obtain sufficient funds on acceptable terms when 
needed could have a negative impact on our business, results of operations, and financial condition. Our future capital requirements will depend 
on many factors, including:  

•                   the results of our preclinical studies and clinical trials;  

•                   the development, formulation and commercialization activities related to ganaxolone;  

•                   the scope, progress, results and costs of researching and developing ganaxolone or any other future product candidates, and 

conducting preclinical studies and clinical trials;  

•                   the timing of, and the costs involved in, obtaining regulatory approvals for ganaxolone or any other future product candidates;  

•                   the cost of commercialization activities if ganaxolone or any other future product candidates are approved for sale, including 

marketing, sales and distribution costs;  

•                   the cost of manufacturing ganaxolone or any other future product candidates in preclinical studies, clinical trials and, if approved, in 

commercial sale;  

•                   our ability to establish and maintain strategic collaborations, licensing or other arrangements and the financial terms of such 

agreements;

Discussion of Critical Accounting Policies and Significant Judgments and Estimates  

We base this management’s discussion and analysis of our financial condition and results of operations on our financial statements, 

which we have prepared in accordance with accounting principles generally accepted in the United States (GAAP). The preparation of our 
financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenue and expenses and 
the disclosure of contingent assets and liabilities in our financial statements. We evaluate our estimates and judgments, including those related to 
warrant liabilities, stock-based compensation and accrued clinical trial expenses on an ongoing basis. We base our estimates on historical 
experience, known trends and events and various other factors that we believe to be reasonable under the circumstances, the results of which form 
the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results 
may differ from these estimates under different assumptions or conditions. You should consider your evaluation of our financial condition and 
results of operations with these policies, judgments and estimates in mind.  

While we describe our significant accounting policies in the notes to our financial statements appearing elsewhere in this Annual Report 
on Form 10-K, we believe the following accounting policies are the most critical to the judgments and estimates we use in the preparation of our 
financial statements.  

Stock-Based Compensation  

We recognize compensation expense related to the fair value of stock-based awards in our statements of operations. For stock options we 
issued to employees, consultants, and members of our board of directors for their services on our board of directors, we estimate the grant-date fair 
value of options using the Black-Scholes option pricing model. The use of the Black-Scholes option pricing model requires management to make

life of the option, risk-free interest rates, and the value of the common stock. For awards subject to time-based vesting, we recognize stock-based 
compensation expense, net of estimated forfeitures, on a straight-line basis over the requisite service period, which is generally the vesting term of 
the award. For awards subject to performance-based vesting conditions, we recognize stock-based compensation expense when it is probable that 
the performance condition will be achieved. We are required to estimate forfeitures at the time of grant and to revise the estimates, if necessary, in 
subsequent periods if actual forfeitures differ from those estimates. We record stock-based awards issued to non-employees at their fair values, 
and periodically revalue them as the equity instruments vest and are recognized as expense over the related service period of the award.  

Clinical Trial Expense Accruals  

As part of the process of preparing our financial statements, we are required to estimate our accrued expenses. Our clinical trial accrual 

process seeks to account for expenses resulting from our obligations under contracts with vendors, consultants and CROs and clinical site 
agreements in connection with conducting clinical trials. The financial terms of these contracts are subject to negotiations, which vary from 
contract to contract and may result in payment flows that do not match the periods over which materials or services are provided to us under such 
contracts. Our objective is to reflect the appropriate clinical trial expenses in our financial statements by matching the appropriate expenses with 
the period in which services and efforts are expended. We account for these expenses according to the progress of the trial as measured by subject 
progression and the timing of various aspects of the trial.  

We determine accrual estimates through financial models that take into account discussion with applicable personnel and outside service 

providers as to the progress or state of completion of trials. During the course of a clinical trial, we adjust our clinical expense recognition if actual 
results differ from our estimates. We make estimates of our accrued expenses as of each balance sheet date in our financial statements based on 
the facts and circumstances known to us at that time. Our clinical trial accrual and prepaid assets are dependent, in part, upon the receipt of timely 
and accurate reporting from CROs and other third-party vendors. Although we do not expect our estimates to differ materially from amounts we 
actually incur, our understanding of the status and timing of services performed relative to the actual status and timing of services performed may 
vary and may result in us reporting amounts that are too high or too low for any particular period.  

JOBS Act  

Section 107 of the JOBS Act also provides that an “emerging growth company” can take advantage of the extended transition period 
provided in Section 7(a)(2)(B) of the Securities Act for complying with new or revised accounting standards. In other words, an “emerging growth 
company” can delay the adoption of new or revised accounting standards until those standards would otherwise apply to private companies. We 
have irrevocably elected not to avail ourselves of this exemption from new or revised accounting standards and, therefore, we will be subject to 
the same new or revised accounting standards as other public companies that are not emerging growth companies.  

Recent Accounting Pronouncements  

In June 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2014-10, Elimination 

of Certain Financial Reporting Requirements, Including an Amendment to Variable Interest Entities Guidance in Topic 810, Consolidation , 
which eliminates all incremental financial reporting requirements for development stage entities by removing Accounting Standards Codification 
(ASC) Topic 915, Development Stage Entities , from the FASB Accounting Standards Codification. ASC Topic 915 is removed effective for 
annual periods beginning after December 15, 2014 and early adoption is permitted. The Company adopted the ASU effective with the issuance of 
the June 30, 2014 interim financial statements.  

In August 2014, the FASB issued ASU No. 2014-15, Disclosure of Uncertainties About an Entity’s Ability to Continue as a Going 
Concern , which provides guidance on determining when and how to disclose going-concern uncertainties in the financial statements.  The new 
standard requires management to perform interim and annual assessments of an entity’s ability to continue as a going concern within one year of 
the date the financial statements are issued.  An entity must provide certain disclosures if conditions or events raise substantial doubt about the 
entity’s ability to continue as a going concern. The ASU applies to all entities and is effective for annual periods ending after December 15, 2016, 
and interim periods thereafter, with early adoption permitted.  The company is currently evaluating the impact the adoption of this ASU will have 
on its financial statements.

Item 7A. Quantitative and Qualitative Discl osures About Market Risk.  

We are exposed to market risks in the ordinary course of our business. These market risks are principally limited to interest rate 

fluctuations.  

We had cash and cash equivalents of $49.7 million at December 31, 2014, consisting primarily of funds in cash and money market 

accounts. The primary objective of our investment activities is to preserve principal and liquidity while maximizing income without significantly 
increasing risk. We do not enter into investments for trading or speculative purposes. Due to the short-term nature of our investment portfolio, we 
do not believe an immediate 1.0% increase in interest rates would have a material effect on the fair market value of our portfolio, and accordingly 
we do not expect a sudden change in market interest rates to affect materially our operating results or cash flows.  

Our long-term debt carries a variable interest rate indexed to the prime rate, with a fixed minimum rate of 6.5%.  The prime rate in the 

U.S. has remained at 3.25% since December of 2008.  While we cannot predict when, if at all, this rate will be increased, we believe the stability 
of the prime rate over the past six years sufficiently mitigates interest rate risk related to our debt.  We do not believe an immediate 1.0% increase 
in the prime rate would have a material effect on the future cash flows related to our debt, and accordingly we do not expect a sudden change in 
the prime rate to affect materially our operating results or cash flows.  

Item 8. Financial Statements an d Supplementary Data.  

Our financial statements, accompanying notes and Report of Independent Registered Public Accounting Firm are included in this Annual 

Report on Form 10-K beginning on page F-1, which are incorporated in this Item 8 by reference.

None.  

Item 9A. Controls and Procedures .  

Evaluation of Disclosure Controls and Procedures.  

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of our 
disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of the end of the period 
covered by this Annual Report on Form 10-K. Management recognizes that any controls and procedures, no matter how well designed and 
operated, can provide only reasonable assurance of achieving their objectives and management necessarily applies its judgment in evaluating the 
cost benefit relationship of possible controls and procedures. Based on such evaluation, our Chief Executive Officer and Chief Financial Officer 
have concluded that, as of the end of the period covered by this report, our disclosure controls and procedures were effective to ensure that the 
information required to be disclosed by the Company in the reports that it files or submits under the Exchange Act is recorded, processed, 
summarized and reported within the time periods specified in SEC rules and forms, and that information required to be disclosed in the reports we 
file or submit under the Exchange Act is accumulated and communicated to our management, including our chief executive officer and principal 
financial and accounting officer, to allow timely decisions regarding required disclosures.  

Management’s Report on Internal Control Over Financial Reporting  

This annual report does not include a report of management’s assessment regarding internal control over financial reporting or an attestation 
report of the Company’s registered public accounting firm due to a transition period established by rules of the SEC for newly public companies.  

Changes in Internal Control Over Financial Reporting

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM  

The Board of Directors and Stockholders  
Marinus Pharmaceuticals, Inc.  

We have audited the accompanying balance sheets of Marinus Pharmaceuticals, Inc. as of December 31, 2014 and 2013, and the related 

statements of operations, convertible preferred stock and stockholders’ equity (deficit), and cash flows for the years then ended. These financial 
statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on 
our audits.  

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those 

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

In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of Marinus 
Pharmaceuticals, Inc. as of December 31, 2014 and 2013, and the results of its operations and its cash flows for the years then ended, in 
conformity with U.S. generally accepted accounting principles.

MARINUS PHARMACEUTICALS, INC.  

NOTES TO FINANCIAL STATEMENTS  

1. Organization and Description of the Business  

We are a biopharmaceutical company dedicated to the development of innovative neuropsychiatric therapeutics. Our clinical stage 

product candidate, ganaxolone, is a synthetic small molecule that is an analog of allopregnanolone, a natural occurring neurosteriod produced by 
 type receptors in the brain, which 
the human body.  Allopregnanolone modulates the activity of gammaaminobutyric acid (GABA) at GABA 
has been identified as playing an important role in certain seizure, psychiatric and developmental disorders.  Our primary focus to date since our 
inception has been directed towards developing business strategies, raising capital, research and development activities and conducting preclinical 
testing and human clinical trials of our product candidates.  

A 

Liquidity  

We have not generated any product revenues and have incurred operating losses since inception. There is no assurance that profitable 

operations will ever be achieved, and if achieved, could be sustained on a continuing basis. In addition, development activities, clinical and 
preclinical testing, and commercialization of our product candidates will require significant additional financing. Our accumulated deficit as of 
December 31, 2014 was $72.3 million and we expect to incur substantial losses in future periods.  We plan to finance our future operations with a 
combination of proceeds from the issuance of equity securities, the issuance of additional debt, potential collaborations and revenues from 
potential future product sales, if any. We have not generated positive cash flows from operations, and there are no assurances that we will be 
successful in obtaining an adequate level of financing for the development and commercialization of our planned product candidates.  

In connection with the closing our initial public offering during the third quarter of 2014, we issued a total of 5,758,000 shares of 

common stock and received aggregate net proceeds, after underwriting discounts and commissions and other estimated offering expenses, of 
approximately $41.2 million.  Our cash and cash equivalents balance as of December 31, 2014 is adequate to fund our operations into the second 
half of 2016.  

2. Summary of Significant Accounting Policies  

Use of Estimates  

The preparation of financial statements in conformity with generally accepted accounting principles (GAAP) requires management to 

make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the 
date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from 
such estimates.  

Recapitalization  

Our board of directors and stockholders approved a reverse stock split of our common stock at a ratio of one share for every six and one-

half shares previously held. The reverse stock split was effected on July 16, 2014. All common stock share and per-share data included in these 
financial statements reflect the reverse stock split. In addition, the board of directors approved an increase in the authorized shares of our common 
stock to 100,000,000 shares.  

Fair Value of Financial Instruments and Credit Risk  

At December 31, 2014 and 2013, our financial instruments included cash and cash equivalents, accounts payable, accrued expenses, 

notes payable and derivative liabilities. The carrying amount of cash and cash equivalents, accounts payable and accrued expenses approximated 
fair value, given their short-term nature. The carrying amount of our notes payable approximate fair value because the interest rates on these 
instruments are reflective of rates that we could obtain on debt with similar terms and conditions. The carrying value of the derivative liabilities 
was the estimated fair value of the liability as more fully described below.

MARINUS PHARMACEUTICALS, INC.  

NOTES TO FINANCIAL STATEMENTS  

Cash and cash equivalents subject us to concentrations of credit risk. However, we invest our cash in accordance with a policy objective 
that seeks to ensure both liquidity and safety of principal. The policy limits investments to instruments issued by the U.S. government and certain 
SEC-registered money market funds that invest only in U.S. government obligations and places restrictions on portfolio maturity terms.  

Cash and Cash Equivalents  

We consider all highly liquid investments that have maturities of three months or less when acquired to be cash equivalents. As of 

December 31, 2014 and 2013, we invested a portion of our cash balances in money market investments, which we have included as cash 
equivalents on our balance sheets.

Property and equipment consist of laboratory and office equipment and are recorded at cost. Property and equipment are depreciated on a 

straight-line basis over their estimated useful lives. We estimate a life of three years for computer equipment, including software, and five years 
for laboratory equipment, office equipment, and furniture. When property and equipment are sold or otherwise disposed of, the cost and related 
accumulated depreciation are removed from the accounts and the resulting gain or loss is included in operating expenses.  

Impairment of Long-Lived Assets  

We review long-lived assets, including property and equipment, for impairment whenever events or changes in business circumstances 

indicate that the carrying amount of an asset may not be fully recoverable. If the estimated undiscounted future cash flows expected to result from 
the use of the asset and its eventual disposition is less than its carrying amount an impairment loss would be recognized if the carrying value of the 
asset exceeded its fair value. Fair value is generally determined using discounted cash flows. Through December 31, 2014, no impairment has 
occurred.  

Research and Development  

Research and development costs are expensed as incurred. Costs for certain development activities, such as clinical trials, are recognized 

based on an evaluation of the progress to completion of specific tasks using data such as subject enrollment, clinical site activations, or 
information provided to us by our vendors with respect to their actual costs incurred. Payments for these activities are based on the terms of the 
individual arrangements, which may differ from the pattern of costs incurred, and are reflected in the financial statements as prepaid or accrued 
research and development expense, as the case may be.  

Income Taxes  

We recognize deferred tax assets and liabilities for temporary differences between the financial reporting basis and the tax basis of our 

assets and liabilities and the expected benefits of net operating loss carryforwards. The impact of changes in tax rates and laws on deferred taxes, 
if any, applied during the years in which temporary differences are expected to be settled, is reflected in the financial statements in the period of 
enactment. The measurement of deferred tax assets is reduced, if necessary, if, based on weight of the evidence, it is more likely than not that 
some, or all, of the deferred tax assets will not be realized. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in 
the period that such tax rate changes are enacted. At December 31, 2014 and 2013, we have concluded that a full valuation allowance is necessary 
for our net deferred tax assets. We had no material amounts recorded for uncertain tax positions, interest or penalties in the accompanying 
consolidated financial statements.  

Loss Per Share of Common Stock  

Basic loss per share is computed by dividing net loss applicable to common stockholders by the weighted average number of shares of 

common stock outstanding during each period. Diluted loss per share includes the effect, if any, from the potential exercise or conversion of 
securities, such as convertible preferred stock, convertible notes payable, warrants, stock options, and unvested restricted stock, which would 
result in the issuance of

incremental shares of common stock. In computing the basic and diluted net loss per share applicable to common stockholders, the weighted 
average number of shares remains the same for both calculations due to the fact that when a net loss exists, dilutive shares are not included in the 
calculation. These potentially dilutive securities are more fully described in Note 7.  

The following table sets forth the computation of basic and diluted earnings per share for the years ended December 31, 2014 and 2013

Comprehensive loss is defined as the change in equity of a business enterprise during a period from transactions and other events and 

circumstances from non-owner sources. Comprehensive loss was equal to net loss for all periods presented.  

Segment Information  

Operating segments are defined as components of an enterprise about which separate discrete information is available for evaluation by 
the chief operating decision maker, or decision-making group, in deciding how to allocate resources and in assessing performance. We view our 
operations and manage our business in one segment, which is the identification and development of neuropsychiatric therapeutics.  

Stock-Based Compensation  

We account for stock-based compensation in accordance with the provisions of Accounting Standards Codification (ASC) Topic 718, 

Compensation—Stock Compensation, or ASC 718, which requires the recognition of expense related to the fair value of stock-based awards in the 
statements of operations. For stock options issued to employees and members of our board of directors for their services on our board of directors, 
we estimate the grant-date fair value of options using the Black-Scholes option pricing model. The use of the Black-Scholes option pricing model 
requires management to make assumptions with respect to the expected term of the option, the

expected volatility of the common stock consistent with the expected life of the option, risk-free interest rates, and the value of the common stock. 
For awards subject to time-based vesting, we recognize stock-based compensation expense, net of estimated forfeitures, on a straight-line basis 
over the requisite service period, which is generally the vesting term of the award. For awards subject to performance-based vesting conditions, 
we recognize stock-based compensation expense when it is probable that the performance condition will be achieved. Stock-based awards issued 
to non-employees are recorded at their fair values, and are periodically revalued as the equity instruments vest and are recognized as expense over 
the related service period in accordance with the provisions of ASC 718 and ASC Topic 505, Equity.  

Clinical Trial Expense Accruals  

As part of the process of preparing our financial statements, we are required to estimate our expenses resulting from our obligations 

under contracts with vendors, clinical research organizations and consultants and under clinical site agreements in connection with conducting 
clinical trials. The financial terms of these contracts are subject to negotiations, which vary from contract to contract and may result in payment 
flows that do not match the periods over which materials or services are provided under such contracts. Our objective is to reflect the appropriate 
trial expenses in our financial statements by matching those expenses with the period in which services are performed and efforts are expended. 
We account for these expenses according to the progress of the trial as measured by patient progression and the timing of various aspects of the 
trial. We determine accrual estimates through financial models taking into account discussion with applicable personnel and outside service 
providers as to the progress or state of consummation of trials. During the course of a clinical trial, we adjust our clinical expense recognition if 
actual results differ from its estimates. We make estimates of our accrued expenses as of each balance sheet date based on the facts and 
circumstances known at that time. Our clinical trial accruals are dependent upon the timely and accurate reporting of contract research 
organizations and other third-party vendors. Although we do not expect our estimates to be materially different from amounts actually incurred, 
our understanding of the status and timing of services performed relative to the actual status and timing of services performed may vary and may 
result in reporting amounts that are too high or too low for any particular period. For the years ended December 31, 2014 and 2013, there were no 
material adjustments to our prior period estimates of accrued expenses for clinical trials.  

Recent Accounting Pronouncements  

In June 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2014-10, Elimination 

of Certain Financial Reporting Requirements, Including an Amendment to Variable Interest Entities Guidance in Topic 810, Consolidation , 
which eliminates all incremental financial reporting requirements for development stage entities by removing Accounting Standards Codification 
(ASC) Topic 915, Development Stage Entities , from the FASB Accounting Standards Codification. ASC Topic 915 is removed effective for 
annual periods beginning after December 15, 2014 and early adoption is permitted. The Company adopted the ASU effective with the issuance of 
the June 30, 2014 interim financial statements.  

In August 2014, the FASB issued ASU No. 2014-15, Disclosure of Uncertainties About an Entity’s Ability to Continue as a Going 

Concern , which provides guidance on determining when and how to disclose going-concern uncertainties in the financial statements.  The new 
standard requires management to perform interim and annual assessments of an entity’s ability to continue as a going concern within one year of 
the date the financial statements are issued.  An entity must provide certain disclosures if conditions or events raise substantial doubt about the 
entity’s ability to continue as a going concern. The ASU applies to all entities and is effective for annual periods ending after December 15, 2016, 
and interim periods thereafter, with early adoption permitted.  The Company is currently evaluating the impact the adoption of this ASU will have 
on its financial statements.  

3. Fair Value Measurements  

FASB accounting guidance defines fair value as the price that would be received to sell an asset or paid to transfer a liability (the exit 

price) in an orderly transaction between market participants at the measurement date. The accounting guidance outlines a valuation framework and 
creates a fair value hierarchy in order to increase the consistency and comparability of fair value measurements and the

Table of Contents

NOTES TO FINANCIAL STATEMENTS  

related disclosures. In determining fair value, we use quoted prices and observable inputs. Observable inputs are inputs that market participants 
would use in pricing the asset or liability based on market data obtained from independent sources.  

The fair value hierarchy is broken down into three levels based on the source of inputs as follows:  

•                   Level 1—Valuations based on unadjusted quoted prices in active markets for identical assets or liabilities.  

•                   Level 2—Valuations based on observable inputs and quoted prices in active markets for similar assets and liabilities.  

•                   Level 3—Valuations based on inputs that are unobservable and models that are significant to the overall fair value measurement.  

The following fair value hierarchy table presents information about each major category of our financial assets and liabilities measured at 

fair value on a recurring basis (in thousands):

We had outstanding warrants to purchase our Series B Preferred Stock, or the Series B Warrants, as of December 31, 2013.  While the 

Series B Preferred Stock was outstanding, holders were able to redeem for cash upon an event that was not within our control, such as the 
liquidation of our preferred stock, as the preferred stockholders had voting control of our company and control of our board of directors, and 
therefore had the ability to trigger the liquidation of our preferred stock.  As a result, the Series B Warrants were recorded as a warrant liability on 
our balance sheet with subsequent changes to fair value recorded on our statements of operations as change in fair value of warrant liability.  In 
connection with our initial public offering during the third quarter of 2014, these warrants expired unexercised, and the Series B Preferred Stock 
underlying the Series B Warrants converted to common stock.  As a result, the fair value of the Series B warrants recorded as a liability as of 
December 31, 2013 was reduced to zero in 2014.  On the grant date and in subsequent periods, we estimated the fair value of the preferred stock 
warrant liability using an option-pricing model, which required inputs such as the expected volatility based on comparable public companies (75% 
- 80%), the estimated fair value of the Series B Preferred Stock ($0.63 - $1.51 per share), and the estimated time to liquidity (0.2 - 4 years). For 
this liability, we developed our own assumptions that do not have observable inputs or available market data to support the fair value.  

The following tables set forth a summary of changes in the fair value of Level 3 preferred stock warrant liability for the years ended 

December 31, 2014 and 2013 (in thousands):

6. Notes Payable  

In April 2014, we borrowed $2.0 million in connection with a term loan pursuant to a Loan and Security Agreement (LSA) we entered 

into with a financial institution.  In connection with this term loan, we issued to the financial institution warrants to purchase 37,991 shares of our 
Series C Preferred Stock with a term of 8 years.  The warrants were net exercised and converted into 220 shares of common stock in connection 
with the closing our initial public offering during the third quarter of 2014.  Pursuant to the terms of the LSA, we made monthly interest-only 
payments for outstanding borrowings at an interest rate equal to the greater of (a) prime plus 2.25% or (b) 5.5% until the LSA was amended in 
December 2014.  

In December 2014, we entered into a First Amendment to Loan and Security Agreement (Amended LSA) with the same financial 

institution.  The Amended LSA increased the total term loan availability from $2.0 million to $12.0 million, available in four tranches (in

* Our ability to borrow under the remaining tranches of $2.5 million each depends upon meeting certain clinical trial milestones.  The 

availability end dates of Tranches C and D are September 1, 2015 and March 31, 2016, respectively.  

In connection with the Amended LSA, we borrowed $5.0 million available to us under Tranche B.  Pursuant to the terms of the 

Amended LSA, we are required to make monthly interest-only payments for all outstanding borrowings at an interest rate equal to the greater of 
(a) prime plus 3.25% or (b) 6.5% until December 2015. Commencing in January 2016 and continuing through December 2017, we are required to 
make monthly payments of 1/24th of our principal borrowings plus interest with the remaining principal balance due in December 2017.  If we 
achieve certain clinical trial milestones by August 2015, both the interest-only period and principal maturity dates will be extended by six months.  

As of December 31, 2014, our outstanding term loan balance of $7.0 million was classified as long-term debt on our balance sheet.  In 

connection with the execution of both the LSA and Amended LSA, we paid debt costs to the financial institution of $25 thousand, which are being 
amortized into interest expense over the remaining term of the loans.  Interest expense related to the loans was $117 thousand for the year ended 
December 31, 2014.  As of December 31, 2014, we had accrued interest of $39 thousand.  There are no financial covenants associated with these 
term loans.  As of December 31, 2014, we were in compliance with all non-financial covenants.

In June 2013, we issued 6,396,065 shares of Series C Preferred Stock at $1.1845 per share for proceeds of $7.5 million, net of issuance 

costs of $46 thousand. In addition, we issued 2,330,955 shares of Series C Preferred Stock from the conversion of the remaining outstanding $2.8 
million in Series C Convertible Notes, including related accrued interest of $461 thousand.  In April 2014, we issued 422,119 shares of Series C 
Preferred Stock. Proceeds of $500 thousand related to this issuance were received in 2013 and were reflected as an investor deposit in accrued 
expenses on the balance sheet as of December 31, 2013.  

In connection with the closing our initial public offering during the third quarter of 2014, all outstanding shares of convertible preferred

8. Stock Option and Incentive Plans  

MARINUS PHARMACEUTICALS, INC.  

NOTES TO FINANCIAL STATEMENTS  

In 2005, we adopted the 2005 Stock Option and Incentive Plan (2005 Plan) that authorizes us to grant options, restricted stock and other 

equity-based awards. As of December 31, 2014, 970,574 options to purchase shares of common stock were outstanding pursuant to grants in 
connection with the 2005 Plan. No addtional shares are available for issuance under the 2005 plan. The amount, terms of grants, and exercisability 
provisions are determined and set by our board of directors.  

Effective in August 2014, we adopted our 2014 Equity Incentive Plan (2014 Plan) that authorizes us to grant options, restricted stock and 

other equity-based awards, subject to adjustment in accordance with the plan.  As of December 31, 2014, 700,000 options to purchase shares of 
common stock were outstanding pursuant to grants in connection with the 2014 Plan; and no shares of common stock were available for future 
issuance.  In accordance with the 2014 Plan, on January 1, 2015, 560,310 shares of common stock became available for future grant under the 
plan.  

There were 1,670,574 stock options outstanding as of December 31, 2014 at a weighted average exercise price of $4.37 per share, and 

54,000 options were granted to nonemployee directors and consultants during the year ended December 31, 2014.  Total compensation cost

The weighted average remaining contractual term of options outstanding and exercisable as of December 31, 2014 is 8.6 and 7.4 years, 
respectively. The aggregate intrinsic value in the preceding tables represent the total intrinsic value that would have been received had all option 
holders exercised their options on December 31, 2014. Intrinsic value is determined by calculating the difference between the fair value of our 
common stock on the last day of the year and the exercise price, multiplied by the number of options.  

The weighted-average grant date fair value of options granted was $6.09 and $0.85 per share in 2014 and 2013 and was estimated at the 

date of grant using the Black-Scholes option-pricing model with the following weighted-average assumptions:  

Expected stock price volatility  
Expected term of options  
Risk-free interest rate  
Expected annual dividend yield  

2014  
77.66 — 86.08%    
5.5 — 6.06 years    
1.75 — 1.98%    
0%    

2013  

103.9 - 118.0%    
5 - 6.25 years    
0.84 - 1.75%    
0%    

The weighted-average valuation assumptions were determined as follows:  

•                   Expected stock price volatility: The expected volatility is based on historical volatilities of similar entities within our industry which 
were commensurate with our expected term assumption as described in the SEC’s Staff Accounting Bulletin, or SAB, No. 107.  

•                   Expected term of options: We estimated the expected term of our stock options with service-based vesting using the “simplified” 
method, as prescribed in SAB No. 107, whereby the expected life equals the average of the vesting tranches and the original 
contractual term of the option due to our lack of sufficient historical data.  

•                   Risk-free interest rate: We base the risk-free interest rate on the interest rate payable on U.S. Treasury securities in effect at the time 

of grant for a period that is commensurate with the assumed expected option term.  

•                   Expected annual dividend yield: The estimated annual dividend yield is 0% because we have not historically paid, and do not expect 

for the foreseeable future to pay, a dividend on our common stock.  

As of December 31, 2014, there was $4.1 million of total unrecognized compensation expense related to unvested stock options granted 

under the 2005 Plan and 2014 Plan. That expense is expected to be recognized in the years ended as follows, in thousands:

In October 2014, we entered into a five-year operating lease agreement for office space in Radnor, Pennsylvania.  Rent payments under 
this lease commence May 1, 2015, with payment amounts escalating each May 1 thereafter through the end of the lease term.  In February 2013, 
we entered into a two-year operating lease agreement for office space in New Haven, Connecticut and pay a flat rent per month over the term of 
the lease which ends in June 2015. Prior to that and through April 2013, we leased a facility in Branford, Connecticut. Rent

We maintain a Section 401(k) retirement plan for all employees. Employees can contribute up to 50% of their eligible pay, subject to 

maximum amounts allowed under law. We may make discretionary profit sharing contributions, which vest over a period of four years from each 
employee’s commencement of employment with us. We have not made any discretionary contributions.  

License Agreement  

We are obligated to pay royalties pursuant to a license agreement with Purdue as a percentage of net product sales for direct licensed 

products, such as ganaxolone. The obligation to pay royalties expires, on a country-by-country basis, 10 years from the first commercial sale of a 
licensed product in each country. The agreement also requires that we pay Purdue a percentage of the non-royalty consideration that we receive 
from a sublicensee and a percentage of milestone payments for indications other than seizure disorders and vascular migraine headaches not 
associated with mood disorders. Under the license agreement, we are committed to use commercially reasonable efforts to develop and 
commercialize at least one licensed product.  

10. Income Taxes  

As of December 31, 2014 and 2013, we had approximately $68.0 million and $59.0 million, respectively, of net operating loss, or NOL, 

carry forwards available to offset future federal and state taxable income that will expire beginning in 2023. We also have federal research and 
development credit carryovers of approximately $2.6 million and state credit carryovers of approximately $0.4 million which expire beginning in 
2019.  

The State of Connecticut provides companies with the opportunity to exchange certain research and development credit carryforwards for 

cash in exchange for foregoing the carryforward. The program provides for such exchange of the research and development credits at a rate of 
65% of the annual research and development credit, as defined. During 2014 and 2013, we recorded a net benefit, in thousands, of $2 and $28, 
respectively, primarily for the estimated proceeds from the exchange of the research and development credit.  

The NOL carry forwards are subject to review and possible adjustment by the Internal Revenue Service and state tax authorities. NOL, 
and tax credit carry forwards may become subject to an annual limitation in the event of certain cumulative changes in the ownership interest of 
significant stockholders over a three-year period in excess of 50%, as defined under Sections 382 and 383 of the Internal Revenue Code of 1986, 
as amended, or the Code, as well as similar state tax provisions. This could limit the amount of NOLs that we can utilize annually to offset future 
taxable income or tax liabilities. The amount of the annual limitation, if any, will be determined based on the value of our company immediately 
prior to an ownership change. Subsequent ownership changes may further affect the limitation in future years. Additionally, U.S. tax laws limit the 
time during which these carry forwards may be

applied against future taxes, therefore, we may not be able to take full advantage of these carry forwards for federal income tax purposes. We are 
currently evaluating the ownership history of our company to determine if there were any ownership changes as defined under Section 382(g) of 
the Code and the effects any ownership change may have had.  

The components of the net deferred tax asset are as follows (in thousands):  

Gross deferred tax assets:

In assessing the realizability of deferred tax assets, we consider whether it is more-likely-than-not that some portion or all of the deferred 
tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the 
periods in which the temporary differences representing net future deductible amounts become deductible. After consideration of all the evidence, 
both positive and negative, we have recorded a full valuation allowance against our net deferred tax assets at December 31, 2014 and 2013, 
respectively, because our management has determined that is it more likely than not that these assets will not be fully realized. The valuation 
allowance increased by $3.9 million and $2.3 million during the years ended December 31, 2014 and 2013, respectively, due primarily to the 
generation of NOLs during those periods.  

We did not have unrecognized tax benefits as of December 31, 2014 and 2013, and do not expect this to change significantly over the 

next twelve months. We recognize interest and penalties accrued on any unrecognized tax benefits as a component of income tax expense. As of 
December 31, 2014 and 2013, we have not accrued interest or penalties related to any uncertain tax positions. Our tax returns filed since inception 
are still subject to examination by major tax jurisdictions.  

A reconciliation of income tax expense (benefit) at the statutory federal income tax rate and income taxes as reflected in the financial 

statements is as follows:

For all years through December 31, 2014, we generated research credits but have not conducted a study to document the qualified 

activities. This study may result in an adjustment to our research and development credit

carryforwards; however, until a study is completed and any adjustment is known, no amounts are being presented as an uncertain tax position for 
these years. A full valuation allowance has been provided against our research and development credits and, if an adjustment is required, this 
adjustment to the deferred tax asset established for the research and development credit carryforwards would be offset by an adjustment to the 
valuation allowance.  

We file income tax returns in the United States, the State of Connecticut, and the Commonwealth of Pennsylvania. The federal and state 

income tax returns are generally subject to tax examinations for the tax years ended December 31, 2011 through December 31, 2013. To the extent 
we have tax attribute carryforwards, the tax years in which the attribute was generated may still be adjusted upon examination by the Internal 
Revenue Service or state tax authorities to the extent utilized in a future period.

AMENDED AND RESTATED  
EMPLOYMENT AGREEMENT  

EXHIBIT 10.3 

EMPLOYMENT AGREEMENT effective as of March 11, 2015 between Marinus Pharmaceuticals, Inc. (the “Company”), a Delaware 

corporation, and Christopher M. Cashman (the “Employee”).  

Recital:  

The Employee has been employed by the Company pursuant to an Employment Agreement dated as of November 2, 2012 (the “Prior 

Agreement”).  The parties desire to enter into this Agreement to amend and restate the Prior Agreement so as to provide for the continued 
employment of the Employee by the Company and for certain other matters in connection with such employment, all as set forth more fully in this 
Agreement.  

NOW, THEREFORE, in consideration of the premises and covenants set forth herein, and intending to be legally bound hereby, the 

parties to this Agreement hereby agree as follows:  

1.                                       Duties.   The Company agrees that the Employee shall be employed by the Company to serve as Chief Executive Officer of the 
Company.  The Employee shall report to the Board of Directors of the Company.  The Employee agrees to be so employed by the Company and to 
devote his best efforts to advance the interests of the Company and to perform such executive, managerial, administrative and financial functions 
as are required to develop the Company’s business and to perform other duties assigned to the Employee by the Board of Directors of the 
Company (the “Board”) that are consistent with the Employee’s position as Chief Executive Officer.  

2.                                       Term.   The Employee’s employment under this Agreement shall continue in effect until terminated pursuant to Section 4 of 

this Agreement.  

3.                                       Compensation.  

(a)                                  Salary.   During the term of the Employee’s employment under this Agreement, the Employee shall be paid an annual 

salary at the rate of not less than $470,000 (the “Base Salary”).  The Base Salary may be increased from time to time by the Board.  The Board 
shall review the Base Salary at least annually at the end of each fiscal year of the Company.  The Base Salary shall be paid in accordance with the 
Company’s regular payroll practices.  

(b)                                  Annual Bonus.   At the end of each fiscal year of the Company that ends during the term of this Agreement, the 

Board shall consider the award of a performance bonus to the Employee for such fiscal year in an amount of up to 50% of the Employee’s Base 
Salary (the “Target Bonus”) based upon the achievement of performance objectives established annually by the Board or its Compensation 
Committee.  Whether the performance objectives for any year have been achieved by the Employee shall be determined by the Board or its 
Compensation Committee.  Notwithstanding the foregoing, all bonuses shall be paid within two and one-half months after the close of each year.  

  
   
   
   
   
   
   
   
   
   
   
 
(c)                                   Equity Incentive Programs.   The Employee shall be eligible to participate in equity incentive programs established 

by the Company from time to time to provide stock options and other equity-based incentives to key employees of the Company in accordance 
with the terms of those programs.  All stock options and restricted stock awards granted to the Employee that vest over time shall, if the 
Employee’s employment is terminated by the Company without Cause in accordance with Section 4(d) or the Employee resigns from the 
Company’s employ for Good Reason in accordance with Section 4(e), in each case upon or during the twelve-month period that immediately 
follows a Change of Control (as defined in Section 4(h)), become fully vested upon the termination of the Employee’s employment to the extent 
permitted by the terms of the applicable plan and subject to the satisfaction by the Employee of the requirements of Section 4(g) of this 
Agreement.  

(d)                                  Vacation and Fringe Benefits.   The Employee shall be entitled to 20 days’ paid vacation, plus an additional two 

floating holidays and two personal days, as per Company policy to be established.  The Employee shall be entitled to participate in all insurance 
and other fringe benefit programs of the Company to the extent and on the same terms and conditions as are accorded to other officers and key 
employees of the Company.  

(e)                                   Reimbursement of Expenses.   The Employee shall be reimbursed for all normal items of travel, entertainment and 
miscellaneous business expenses reasonably incurred by the Employee on behalf of the Company, provided that such expenses are documented 
and submitted in accordance with the reimbursement policies of the Company as in effect from time to time.  

4.                                       Termination.  

(a)                                  Death.   This Agreement shall automatically terminate effective as of the date of the Employee’s death, in which event 

the Company shall not have any further obligation or liability under this Agreement except that the Company shall pay to the Employee’s estate:  
(i) any portion of the Employee’s Base Salary for the period up to the Employee’s date of death that has been earned but remains unpaid; and 
(ii) any benefits that have accrued to the Employee under the terms of the employee benefit plans of the Company, which benefits shall be paid in 
accordance with the terms of those plans.  

(b)                                  Total Disability.   The Company may terminate the employment of the Employee immediately upon written notice to 
the Employee in the event of the Disability (as that term is hereinafter defined) of the Employee, in which event, the Company shall not have any 
further obligation or liability under this Agreement except that the Company shall pay to the Employee:  (i) any portion of the Employee’s Base 
Salary for the period up to the date of termination that has been earned but remains unpaid; and (ii) any benefits that have accrued to the Employee 
under the terms of the employee benefit plans of the Company, which benefits shall be paid in accordance with the terms of those plans.  The term 
“Disability,” when used herein, shall mean an illness, incapacity or a mental or physical condition that renders the Employee unable or 
incompetent to carry out the job responsibilities that the Employee held or the tasks that the Employee was assigned at the time the disability 
commenced, as determined by the Board and supported by the opinion of a physician.  The Employee shall fully cooperate with  

2  

   
   
   
   
   
   
   
 
the physician retained to furnish such opinion, including submitting to such examinations and tests as may be requested by the physician.  

(c)                                   Termination by the Company for Cause.   The Company may terminate the Employee’s employment hereunder 

upon written notice to the Employee for any of the following reasons:  (i) the Employee’s misuse of alcoholic beverages, controlled substances or 
other narcotics, which misuse has had or is reasonably likely to have a material adverse effect on the business or financial affairs of the Company 
or the reputation of the Company; (ii) failure by the Employee to cooperate with the Company in any investigation or formal proceeding; (iii) the 
commission by the Employee of, or a plea by the Employee of guilty or nolo contendere with respect to, or conviction of the Employee for, a 
felony (or any lesser included offense or crime in exchange for withdrawal of a felony indictment or charged crime that might result in a penalty 
of incarceration), a crime involving moral turpitude, or any other offense that results in or could result in any prison sentence; (iv) adjudication as 
an incompetent; (v) a breach by the Employee of any material term of this Agreement, including the Employee’s failure to faithfully, diligently 
and adequately perform the Employee’s duties under this Agreement, that is not corrected within ten days after written notice from the Company, 
which notice shall set forth the nature of the breach; (vi) violation in any material respect of any of the Company’s rules, regulations or policies; 
(vii) gross insubordination by the Employee in the performance of the Employee’s duties under this Agreement; (viii) engaging in any conduct, 
action or behavior that, in the reasonable opinion of the Board, has had a material adverse effect on the reputation of the Company or the 
Employee; (ix) any continued or repeated absence from the Company, unless the absence is approved or excused by the Board or the result of the 
Employee’s illness, disability or incapacity (in which event the provisions of Section 4(b) hereof shall control); or (x) misappropriation of any 
funds or property of the Company, theft, embezzlement or fraud.  In the event that the Company shall discharge the Employee pursuant to this 
Section 4(c), the Company shall not have any further obligation or liability under this Agreement, except that the Company shall pay to the 
Employee:  (i) any portion of the Employee’s Base Salary for the period up to the date of termination that has been earned but remains unpaid; and 
(ii) any benefits that have accrued to the Employee under the terms of the employee benefit plans of the Company, which benefits shall be paid in 
accordance with the terms of those plans.  

(d)                                  Other Termination by the Company.   The Company may terminate the employment of the Employee for any 

reason other than one specified in Section 4(b) or 4(c) hereof immediately upon written notice to the Employee, in which event the Employee shall 
be entitled to receive:  (i) any portion of the Employee’s Base Salary for the period up to the date of termination that has been earned but remains 
unpaid; (ii) any benefits that have accrued to the Employee under the terms of any employee benefit plans of the Company, which benefits shall 
be paid in accordance with the terms of those plans; and (iii) subject to the satisfaction of the provisions of Section 4(g) and the compliance by the 
Employee with all terms and provisions of this Agreement that survive the termination of the Employee’s employment by the Company, (A) the 
Employee’s Base Salary for a period of twelve months, less applicable taxes and withholdings, payable in accordance with the Company’s regular 
payroll practices, with an accelerated payment of any balance upon the occurrence of a Change in Control; provided, however, that if such 
termination of employment shall occur within three months before or within twelve months after the occurrence of a Change in Control (such 
period being referred to herein as the “Change in Control Period”), the severance payable to the Employee shall be  

3  

   
   
   
   
 
increased to an amount equal to the Employee’s Base Salary for a period of 24 months and be payable in a single lump sum payment, less 
applicable taxes and withholdings; (B) payment or reimbursement (upon presentation of proof of payment) of the Employee’s medical insurance 
premiums at the same level as was in effect on the termination date for a period of twelve months, which period shall increase to 24 months if 
such termination of employment shall occur within the Change in Control Period; and (C) if such termination of employment shall occur within 
the Change in Control Period, an amount equal to the Employee’s Target Bonus for the year in which such employment termination shall occur, 
prorated based on the relative number of days in such year during which the Employee was employed by the Company and/or its successor in the 
Change in Control, payable in a single lump sum payment, less applicable taxes and withholdings.  Any severance payments and lump sum 
payments due hereunder shall commence as soon as administratively feasible within 60 days after the date of the Employee’s termination of 
employment provided the Employee has timely executed and returned the Release referred to in Section 4(g) and, if a revocation period is 
applicable, the Employee has not revoked the Release; provided, however, that if the 60-day period begins in one calendar year and ends in a 
second calendar year, the severance payments shall begin to be paid in the second calendar year.  On the date that severance payments commence, 
the Company will pay the Employee in a single lump sum payment, less applicable taxes and withholding, the severance payments that the 
Employee would have received on or prior to such date but for the delay imposed by the immediately preceding sentence, with the balance of the 
severance payments to be paid as originally scheduled.  

(e)                                   Termination by the Employee for Good Reason.   The Employee may terminate the Employee’s employment by 

providing written notice to the Company of a breach constituting Good Reason.  “Good Reason” shall be deemed to exist with respect to any 
termination of employment by the Employee for any of the following reasons:  (i) a reassignment of the Employee to a location outside the 
Greater Philadelphia area; (ii) any material failure by the Company to comply with any material term of this Agreement; (iii) the demotion of the 
Employee to a lesser position than described in Section 1 hereof or a substantial diminution of the Employee’s authority, duties or responsibilities 
as in effect on the date of this Agreement or as hereafter increased; or (iv) a material diminution of the Executive’s Base Salary and benefits, in 
the aggregate, unless such reduction is part of a Company-wide reduction in compensation and/or benefits for all of its senior executives.  If the 
Employee shall terminate the Employee’s employment hereunder for Good Reason, the Employee shall be entitled to receive the same payments 
and benefits on the same terms and conditions as would be applicable upon a termination of the Employee’s employment by the Company without 
Cause, as provided in Section 4(d) and subject to the satisfaction of the other provisions of this Section 4(e).  The Employee may not resign with 
Good Reason pursuant to this Section 4(e), and shall not be considered to have done so for any purpose of this Agreement, unless (A) the 
Employee, within 60 days after the initial existence of the act or failure to act by the Company that constitutes “Good Reason” within the meaning 
of this Agreement, provides the Company with written notice that describes, in particular detail, the act or failure to act that the Employee believes 
to constitute “Good Reason” and identifies the particular clause of this Section 4(e) that the Employee contends is applicable to such act or failure 
to act; (B) the Company, within 30 days after its receipt of such notice, fails or refuses to rescind such act or remedy such failure to act so as to 
eliminate “Good Reason” for the termination by the Employee of the Employee’s employment relationship with the Company, and (C) the 
Employee actually resigns from the  

4  

   
   
   
 
employ of the Company on or before that date that is six calendar months after the initial existence of the act or failure to act by the Company that 
constitutes “Good Reason.”  If the requirements of the preceding sentence are not fully satisfied on a timely basis, then the resignation by the 
Employee from the employ of the Company shall not be deemed to have been for “Good Reason,” the Employee shall not be entitled to any of the 
benefits to which the Employee would have been entitled if the Employee had resigned from the employ of the Company for “Good Reason,” and 
the Company shall not be required to pay any amount or provide any benefit that would otherwise have been due to the Employee under this 
Section 4(e) had the Employee resigned with “Good Reason.”  

(f)                                    Other Termination by the Employee.   The Employee may terminate the Employee’s employment for any reason 

other than one specified in Section 4(e) upon at least 30 days’ prior written notice to the Company, which notice shall specify the effective date of 
the termination.  In the event the Employee shall terminate the Employee’s employment pursuant to this Section 4(f), the Company shall not have 
any further obligation or liability under this Agreement, except that the Company shall pay to the Employee:  (i) any portion of the Employee’s 
Base Salary for the period up to the date of termination that has been earned but remains unpaid; and (ii) any benefits that have accrued to the 
Employee under the terms of the employee benefit plans of the Company, which benefits shall be paid in accordance with the terms of those plans. 

(g)                                  Execution of Release.  The Employee shall not be entitled to any payments or benefits under Sections 4(d) or 4

(e) unless the Employee executes and does not revoke a Release and Agreement (the “Release”), as drafted at the time of the Employee’s 
termination of employment, including, but not limited to:  

(i)                                      an unconditional release of all rights to any claims, charges, complaints, grievances, known or unknown to 
the Employee, against the Company, its affiliates or assigns, through the date of the Employee’s termination from employment other than post-
termination payments and benefits pursuant to this Agreement;  

grievances against the Company, its affiliates, or assigns;  

(ii)                                   a representation and warranty that the Employee has not filed or assigned any claims, charges, complaints, or 

to return any such confidential information and property to the Company upon execution of the Release;  

(iii)                                an agreement not to use, disclose or make copies of any confidential information of the Company, as well as 

of employment;  

(iv)                               a mutual agreement to maintain the confidentiality of the Release or disclose the reasons for any termination 

(v)                                  an agreement not to disparage the Company or its officers, directors, stockholders, products or business; and  

any portion of this Agreement or the Release.  

(vi)                               an agreement to indemnify the Company, or its affiliates or assigns, in the event that the Employee breaches 

5  

   
   
   
   
   
   
   
   
   
   
 
Notwithstanding any provision of this Agreement to the contrary, in no event shall the timing of the Employee’s execution of the Release, directly 
or indirectly, result in the Employee designating the calendar year of payment, and if a payment that is subject to execution of the Release could 
be made in more than one taxable year, payment shall be made in the later taxable year.  

(h)                                  Definition of Change in Control.   As used in this Agreement, the term “Change in Control” means:  

(i)                                      any merger or consolidation in which voting securities of the Company possessing more than 50% of the total 

combined voting power of the Company’s outstanding securities are transferred to a person or persons different from the person holding those 
securities immediately prior to such transaction and the composition of the Board following such transaction is such that the directors of the 
Company prior to the transaction constitute less than 50% of the Board membership following the transaction;  

(ii)                                   any acquisition, directly or indirectly, by a person or related group of persons (other than the Company or a 

person that directly or indirectly controls, is controlled by, or is under common control with, the Company) of beneficial ownership of voting 
securities of the Company possessing more than 50% of the total combined voting power of the Company’s outstanding securities; provided, 
however, that, no Change in Control shall be deemed to occur by reason of the acquisition of shares of the Company’s capital stock by an investor 
or group of investors in the Company in a capital-raising transaction; or  

the Company; or  

(iii)                                any sale, transfer, exclusive worldwide license or other disposition of all or substantially all of the assets of 

(iv)                               within any 24-month period beginning on or after the date hereof, the persons who were directors of the 

Company immediately before the beginning of such period (the “Incumbent Directors”) shall cease (for any reason other than death) to constitute 
at least a majority of the Board of Directors of the Company or the board of directors of any successor to the Company, provided that any director 
who was not a director as of the date hereof shall be deemed to be an Incumbent Director if such director was elected to the Board by, or on the 
recommendation of or with the approval of, at least two-thirds of the directors who then qualified as Incumbent Directors either actually or by 
prior operation of this Section 4(h)(iv), unless such election, recommendation or approval was the result of an actual or threatened contested 
election of directors pursuant to Regulation 14A under the Securities Exchange Act of 1934 or any successor provision.  

(i)                                     Base Salary Continuation.  The Base Salary continuation set forth in Sections 4(d) and (e) above shall be intended 
either (i) to satisfy the safe harbor set forth in the regulations issued under section 409A of the Internal Revenue Code of 1986, as amended (the 
“Code”) (Treas. Regs. 1.409A-1(n)(2)(ii)) or (ii) be treated as a Short-term Deferral as that term is defined under Code section 409A (Treas. Regs. 
1.409A-1(b)(4)).  To the extent such continuation payments exceed the applicable safe harbor amount or do not constitute a Short-term Deferral, 
the excess amount shall be treated as deferred compensation under Code section 409A and as such shall be payable pursuant to the following 
schedule: such excess amount shall  

6  

   
   
   
   
   
   
   
   
 
be paid via standard payroll in periodic installments in accordance with the Company’s usual practice for its senior executives.  Solely for 
purposes of Code section 409A, each installment payment is considered a separate payment.  Notwithstanding any provision in this Agreement to 
the contrary, in the event that the Employee is a “specified employee” as defined in Section 409A, any continuation payment, continuation 
benefits or other amounts payable under this Agreement that would be subject to the special rule regarding payments to “specified employees” 
under Section 409A(a)(2)(B) of the Code shall not be paid before the expiration of a period of six months following the date of the Employee’s 
termination of employment or before the date of the Employee’s death, if earlier.  

(j)                                     Parachute Provisions.   Notwithstanding any provisions of this Agreement to the contrary:  

(i)                                      If any of the payments or benefits received or to be received by the Employee in connection with the 

Employee’s termination of employment in respect of a Change in Control, whether pursuant to the terms of this Agreement or any other plan, 
arrangement or agreement with the Company (all such payments and benefits, being hereinafter referred to as the “Total Payments”), would be 
subject to the excise tax (the “Excise Tax”) imposed under Section 4999 of the Code, the Employee shall receive the Total Payments and be 
responsible for the Excise Tax; provided, however that the Employee shall not receive the Total Payments and the Total Payments shall be 
reduced to the Safe Harbor Amount (defined below) if (A) the net amount of such Total Payments, as so reduced to the Safe Harbor Amount (and 
after subtracting the net amount of federal, state and local income taxes on such reduced Total Payments) is greater than or equal to (B) the net 
amount of such Total Payment without such reduction (but after subtracting the net amount of federal, state and local income taxes on such Total 
Payments and the amount of Excise Tax to which the Employee would be subject in respect of such unreduced Total Payments).  The “Safe 
Harbor Amount” is the amount to which the Total Payments would hypothetically have to be reduced so that no portion of the Total Payments 
would be subject to the Excise Tax.  

(ii)                                   For purposes of determining whether any of the Total Payments will be subject to the Excise Tax and the 

amount of such Excise Tax, (A) all of the Total Payments shall be treated as “parachute payments” (within the meaning of Section 280G(b)(2) of 
the Code) unless, in the opinion of tax counsel (“Tax Counsel”) selected by the accounting firm that was, immediately prior to the Change in 
Control, the Company’s independent auditor (the “Auditor”), such payments or benefits (in whole or in part) do not constitute parachute 
payments, including by reason of Section 280G(b)(4)(A) of the Code, (B) all “excess parachute payments” within the meaning of Section 280G(b)
(1) of the Code shall be treated as subject to the Excise Tax unless, in the opinion of Tax Counsel, such excess parachute payments (in whole or in 
part) represent reasonable compensation for services actually rendered (within the meaning of Section 280G(b)(4)(B) of the Code) in excess of the 
base amount (within the meaning of Section 280G(b)(3) of the Code) allocable to such reasonable compensation, or are otherwise not subject to 
the Excise Tax, and (C) the value of any noncash benefits or any deferred payment or benefit shall be determined by the Auditor in accordance 
with the principles of Sections 280G(d)(3) and (4) of the Code.  If the Auditor is prohibited by applicable law or regulation from performing the 
duties assigned to it hereunder, then a different auditor, acceptable to both the Company and  

7  

   
   
   
   
   
 
Employee, shall be selected.  The fees and expenses of Tax Counsel and the Auditor shall be paid by the Company.  

(iii)                                In the event it is determined that the Safe Harbor Amount is payable to Employee, then the severance 
payments provided under this Agreement that are cash shall first be reduced on a pro rata basis, and the non-cash severance payments shall 
thereafter be reduced on a pro rata basis, to the extent necessary so that no portion of the Total Payments is subject to the Excise Tax.  

5.                                       Non-Disclosure and Non-Competition.  

(a)                                  Non-Disclosure.   The Employee acknowledges that in the course of performing services for the Company, the 

Employee will obtain knowledge of the Company’s business plans, products, processes, software, know-how, trade secrets, formulas, methods, 
models, prototypes, discoveries, inventions, improvements, disclosures, names and positions of employees and/or other proprietary and/or 
confidential information (collectively the “Confidential Information”).  The Employee agrees to keep the Confidential Information secret and 
confidential and not to publish, disclose or divulge to any other party, and the Employee agrees not to use any of the Confidential Information for 
the Employee’s own benefit or to the detriment of the Company without the prior written consent of the Company, whether or not such 
Confidential Information was discovered or developed by the Employee.  The Employee also agrees not to divulge, publish or use any proprietary 
and/or confidential information of others that the Company is obligated to maintain in confidence.  

(b)                                  Non-Competition.   The Employee agrees that, during the Employee’s employment by the Company hereunder and 
for an additional period of one year after the termination of the Employee’s employment hereunder, neither the Employee nor any corporation or 
other entity in which the Employee may be interested as a partner, trustee, director, officer, employee, agent, shareholder, lender of money or 
guarantor, or for which the Employee performs services in any capacity (including as a consultant or independent contractor) shall at any time 
during such period (i) be engaged, directly or indirectly, in any Competitive Business (as that term is hereinafter defined) or (ii) solicit, hire, 
contract for services or otherwise employ, directly or indirectly, any of the employees of the Company.  For purposes of this Section 5(b) the term 
“Competitive Business” shall mean any firm or business organization that competes with the Company in the development and/or 
commercialization of drugs that prevent or treat partial complex seizures, post-traumatic stress disorder or fragile-x syndrome or any other 
Ganaxolone-related technology, product or service being developed, manufactured, marketed, distributed or planned in writing by the Company at 
the time of termination of the Employee’s employment with the Company. The foregoing prohibition shall not prevent any employment or 
engagement of the Employee, after termination of employment with the Company, by any company or business organization not substantially 
engaged in a Competitive Business as long as the activities of any such employment or engagement, in any capacity, do not involve work on 
matters related to any product or service being developed, manufactured, marketed, distributed or planned in writing by the Company at the time 
of termination of Employee’s employment with the Company.  The Employee’s ownership of no more than 5% of the outstanding voting stock of 
a publicly traded company shall not constitute a violation of this Section 5(b).  The Employee is entering into this covenant not to compete to 
continue the Employee’s undertaking  

8  

   
   
   
   
   
   
 
in the Prior Agreement and in consideration of the additional agreements of the Company in this Agreement, including but not limited to the rights 
of the Employee set forth in Sections 4(d) and 4(e).  

6.                                       Inventions and Discoveries.  

(a)                                  Disclosure.   The Employee shall promptly and fully disclose to the Company, with all necessary detail, all 

developments, know-how, discoveries, inventions, improvements, concepts, ideas, formulae, processes and methods (whether copyrightable, 
patentable or otherwise) made, received, conceived, acquired or written by the Employee (whether or not at the request or upon the suggestion of 
the Company, solely or jointly with others), during the period of the Employee’s employment with the Company that (i) result from, arise out of, 
or relate to any work, assignment or task performed by the Employee on behalf of the Company, whether undertaken voluntarily or assigned to the 
Employee within the scope of the Employee’s responsibilities to the Company, or (ii) were developed using the Company’s facilities or other 
resources or in Company time, or (iii) result from the Employee’s use or knowledge of the Company’s Confidential Information, or (iv) relate to 
the Company’s business or any of the products or services being developed, manufactured or sold by the Company or that may be used in relation 
therewith (collectively referred to as “Inventions”).  The Employee hereby acknowledges that all original works of authorship that are made by the 
Employee (solely or jointly with others) within the above terms and that are protectable by copyright are “works made for hire,” as that term is 
defined in the United States Copyright Act.  The Employee understands and hereby agrees that the decision whether or not to commercialize or 
market any Invention developed by the Employee solely or jointly with others is within the Company’s sole discretion and for the Company’s sole 
benefit and that no royalty shall be due to the Employee as a result of the Company’s efforts to commercialize or market any such Invention.  

(b)                                  Assignment and Transfer.   The Employee agrees to assign and transfer to the Company all of the Employee’s right, 

title and interest in and to the Inventions, and the Employee further agrees to deliver to the Company any and all drawings, notes, specifications 
and data relating to the Inventions, and to sign, acknowledge and deliver all such further papers, including applications for and assignments of 
copyrights and patents, and all renewals thereof, as may be necessary to obtain copyrights and patents for any Inventions in any and all countries 
and to vest title thereto in the Company and its successors and assigns and to otherwise protect the Company’s interests therein.  The Employee 
shall not charge the Company for time spent in complying with these obligations.  If the Company is unable because of the Employee’s mental or 
physical incapacity or for any other reason to secure the Employee’s signature to apply for or to pursue any application for any United States or 
foreign patents or copyright registrations covering Inventions or original works of authorship assigned to the Company as above, then the 
Employee hereby irrevocably designates and appoints the Company and its duly authorized officers and agents as the Employee’s agent and 
attorney in fact, to act for and in the Employee’s behalf and stead to execute and file any such applications and to do all other lawfully permitted 
acts to further the prosecution and issuance of letters patent or copyright registrations thereon with the same legal force and effect as if executed 
by the Employee.  

the Company, the Employee will maintain careful,  

(c)                                   Records.   The Employee agrees that in connection with any research, development or other services performed for 

9  

   
   
   
   
   
   
 
adequate and contemporaneous written records of all Inventions, which records shall be the property of the Company.  

7.                                       Company Documentation.   The Employee shall hold in a fiduciary capacity for the benefit of the Company all 

documentation, disks, programs, data, records, drawings, manuals, reports, sketches, blueprints, letters, notes, notebooks and all other writings, 
electronic data, graphics and tangible information and materials of a secret, confidential or proprietary information nature relating to the Company 
or the Company’s business that are in the possession or under the control of the Employee.  

8.                                       Injunctive Relief.   The Employee acknowledges that the Employee’s compliance with the agreements in Sections 5, 6 and 7 

hereof is necessary to protect the good will and other proprietary interests of the Company and that the Employee is one of the principal 
executives of the Company and conversant with its affairs, its trade secrets and other proprietary information.  The Employee acknowledges that a 
breach of any of the Employee’s agreements in Sections 5, 6 and 7 hereof will result in irreparable and continuing damage to the Company for 
which there will be no adequate remedy at law; and the Employee agrees that in the event of any breach of the aforesaid agreements, the Company 
and its successors and assigns shall be entitled to injunctive relief and to such other and further relief as may be proper.

shall be deemed to be modified or restricted to the extent and in the manner necessary to render the same valid and enforceable, or shall be 
deemed excised from this Agreement, as the case may require, and this Agreement shall be construed and enforced to the maximum extent 
permitted by law as if such provision had been originally incorporated herein as so modified or restricted or as if such provision had not been

10  

   
   
   
   
   
   
   
   
   
   
 
the Company.  This Agreement may be assigned by the Company without the consent of the Employee.  

(b)                                  By the Employee.   This Agreement and the obligations created hereunder may not be assigned by the Employee, but

14.                                Notices.   All notices required or permitted to be given hereunder shall be in writing and shall be deemed to have been given

Any party may from time to time change its address for the purpose of notices to that party by a similar notice specifying a new address, but no 
such change shall be deemed to have been given until it is actually received by the party sought to be charged with its contents.  

15.                                Waivers.   No claim or right arising out of a breach or default under this Agreement shall be discharged in whole or in part by a

party’s duly authorized agent.  A waiver by any party hereto of a breach or default by the other party hereto of any provision of this Agreement 
shall not be deemed a waiver of future compliance therewith, and such provisions shall remain in full force and effect.  

16.                                Section 409A.   It is intended that this Agreement be drafted and administered in compliance with section 409A of the Code, 

including, but not limited to, any future amendments to Code section 409A, and any other Internal Revenue Service or other governmental rulings 
or interpretations (together, “Section 409A”) issued pursuant to Section 409A so as not to subject the Employee to payment of interest or any 
additional tax under Code section 409A.  The parties intend for any payments under this Agreement to either satisfy the requirements of 
Section 409A or to be exempt from the application of Section 409A, and this Agreement shall be construed and interpreted accordingly.  In 
furtherance thereof, if payment or provision of any amount or benefit hereunder that is subject to Section 409A at the time specified herein would 
subject such amount  

11  

   
   
   
   
   
   
   
   
   
   
   
 
or benefit to any additional tax under Section 409A, the payment or provision of such amount or benefit shall be postponed to the earliest 
commencement date on which the payment or provision of such amount or benefit could be made without incurring such additional tax.  In 
addition, to the extent that any Internal Revenue Service guidance issued under Section 409A would result in the Employee being subject to the 
payment of interest or any additional tax under Section 409A, the parties agree, to the extent reasonably possible, to amend this Agreement in 
order to avoid the imposition of any such interest or additional tax under Section 409A, which amendment shall have the minimum economic 
effect necessary and be reasonably determined in good faith by the Company and the Employee.  

17.                                Survival of Covenants.   The provisions of Sections 4, 5, 6, 7 and 8 hereof shall survive the termination of this Agreement.  

Furthermore, each other provision of this Agreement that, by its terms, is intended to continue beyond the termination of the Employee’s 
employment shall continue in effect thereafter.

AMENDED AND RESTATED  
EMPLOYMENT AGREEMENT  

EXHIBIT 10.4 

EMPLOYMENT AGREEMENT effective as of March 11, 2015 between Marinus Pharmaceuticals, Inc. (the “Company”), a Delaware 

corporation, and Edward F. Smith (the “Employee”).  

Recital:  

The Employee has been employed by the Company pursuant to an Employment Agreement dated as of November 2, 2012 (the “Prior 

Agreement”).  The parties desire to enter into this Agreement to amend and restate the Prior Agreement so as to provide for the continued 
employment of the Employee by the Company and for certain other matters in connection with such employment, all as set forth more fully in this 
Agreement.  

NOW, THEREFORE, in consideration of the premises and covenants set forth herein, and intending to be legally bound hereby, the 

parties to this Agreement hereby agree as follows:  

1.                                       Duties.   The Company agrees that the Employee shall be employed by the Company to serve as Chief Financial Officer of the 
Company.  The Employee shall report to the Chief Executive Officer of the Company (the “CEO”).  The Employee agrees to be so employed by 
the Company and to devote his best efforts to advance the interests of the Company and to perform the duties customarily incident to the position 
of Chief Financial Officer and such other duties assigned to the Employee by the CEO, provided such other duties are commensurate with the 
Employee’s employment level at the Company.  Notwithstanding anything in this Agreement to the contrary, the Employee shall be permitted to 
serve of the board of directors (or equivalent governing bodies) of one company that is unrelated to, and not competitive with the business of, the 
Company, provided such service does not materially interfere with the Employee’s duties and responsibilities to the Company.  Participation on 
more than one board shall be subject to the approval by the CEO.  

2.                                       Term.   The Employee’s employment under this Agreement shall continue in effect until terminated pursuant to Section 4 of 

this Agreement.  

3.                                       Compensation.  

(a)                                  Salary.  During the term of the Employee’s employment under this Agreement, the Employee shall be paid an annual 

salary at the rate of not less than $350,000 (the “Base Salary”).  The Base Salary may be increased from time to time by the Board of Directors 
(the “Board”).  The Board shall review the Base Salary at least annually at the end of each fiscal year of the Company.  The Base Salary shall be 
paid in accordance with the Company’s regular payroll practices.  

(b)                                  Annual Bonus.   At the end of each fiscal year of the Company that ends during the term of this Agreement, the 

Board shall consider the award of a performance bonus to the Employee for such fiscal year in an amount of up to 35% of the Employee’s Base 
Salary (the  

  
   
   
   
   
   
   
   
   
   
   
 
“Target Bonus”) based upon the achievement of performance objectives established annually by the Board or its Compensation Committee.  
Whether the performance objectives for any year have been achieved by the Employee shall be determined by the Board or its Compensation 
Committee.  Notwithstanding the foregoing, all bonuses shall be paid within two and one-half months after the close of each year.  

(c)                                   Equity Incentive Programs.   The Employee shall be eligible to participate in equity incentive programs established 

by the Company from time to time to provide stock options and other equity-based incentives to key employees of the Company in accordance 
with the terms of those programs. All stock options and restricted stock awards granted to the Employee that vest over time shall, if the 
Employee’s employment is terminated by the Company without Cause in accordance with Section 4(d) or the Employee resigns from the 
Company’s employ for Good Reason in accordance with Section 4(e), in each case upon or during the twelve-month period that immediately 
follows a Change in Control (as defined in Section 4(h)), become fully vested upon the termination of the Employee’s employment to the extent 
permitted by the terms of the applicable plan and subject to the satisfaction by the Employee of the requirements of Section 4(g) of this 
Agreement.  

(d)                                  Vacation and Fringe Benefits.   The Employee shall be entitled to 20 days’ paid vacation, plus an additional two 

floating holidays and two personal days, as per Company policy to be established.  The Employee shall be entitled to participate in all insurance 
and other fringe benefit programs of the Company to the extent and on the same terms and conditions as are accorded to other officers and key 
employees of the Company.  

(e)                                   Reimbursement of Expenses.   The Employee shall be reimbursed for all normal items of travel, entertainment and 
miscellaneous business expenses reasonably incurred by the Employee on behalf of the Company, provided that such expenses are documented 
and submitted in accordance with the reimbursement policies of the Company as in effect from time to time.  

4.                                       Termination.  

(a)                                  Death.   This Agreement shall automatically terminate effective as of the date of the Employee’s death, in which event 

the Company shall not have any further obligation or liability under this Agreement except that the Company shall pay to the Employee’s estate:  
(i) any portion of the Employee’s Base Salary for the period up to the Employee’s date of death that has been earned but remains unpaid; and 
(ii) any benefits that have accrued to the Employee under the terms of the employee benefit plans of the Company, which benefits shall be paid in 
accordance with the terms of those plans.  

(b)                                  Total Disability.   The Company may terminate the employment of the Employee immediately upon written notice to 
the Employee in the event of the Disability (as that term is hereinafter defined) of the Employee, in which event, the Company shall not have any 
further obligation or liability under this Agreement except that the Company shall pay to the Employee:  (i) any portion of the Employee’s Base 
Salary for the period up to the date of termination that has been earned but remains unpaid; and (ii) any benefits that have accrued to the Employee 
under the terms of the employee benefit plans of the Company, which benefits  

2  

   
   
   
   
   
   
   
   
 
shall be paid in accordance with the terms of those plans.  For purposes of this Agreement, the term “Disability” shall mean an illness, incapacity 
or a mental or physical condition that renders the Employee unable or incompetent to carry out the job responsibilities that the Employee held or 
the tasks that the Employee was assigned at the time the disability commenced, as determined by the Board and supported by the opinion of a 
physician.  The Employee shall fully cooperate with the physician retained to furnish such opinion, including submitting to such examinations and 
tests as may be requested by the physician.  

(c)                                   Termination by the Company for Cause.   The Company may terminate the Employee’s employment hereunder 

upon written notice to the Employee for any of the following reasons:  (i) the Employee’s misuse of alcoholic beverages, controlled substances or 
other narcotics, which misuse has had or is reasonably likely to have a material adverse effect on the business or financial affairs of the Company 
or the reputation of the Company; (ii) failure by the Employee to cooperate with the Company in any investigation or formal proceeding; (iii) the 
commission by the Employee of, or a plea by the Employee of guilty or nolo contendere with respect to, or conviction of the Employee for, a 
felony (or any lesser included offense or crime in exchange for withdrawal of a felony indictment or charged crime that might result in a penalty 
of incarceration), a crime involving moral turpitude, or any other offense that results in or could result in any prison sentence; (iv) adjudication as 
an incompetent; (v) a breach by the Employee of any material term of this Agreement, including the Employee’s failure to faithfully, diligently 
and adequately perform the Employee’s duties under this Agreement, that is not corrected within ten days after written notice from the Company, 
which notice shall set forth the nature of the breach; (vi) violation in any material respect of any of the Company’s rules, regulations or policies; 
(vii) gross insubordination by the Employee in the performance of the Employee’s duties under this Agreement; (viii) engaging in any conduct, 
action or behavior that, in the reasonable opinion of the Company, has had a material adverse effect on the reputation of the Company or the 
Employee; (ix) any continued or repeated absence from the Company, unless the absence is approved or excused by the CEO or the result of the 
Employee’s illness, disability or incapacity (in which event the provisions of Section 4(b) hereof shall control); or (x) misappropriation of any 
funds or property of the Company, theft, embezzlement or fraud.  For the avoidance of doubt, “Cause” shall not mean a failure to achieve 
scientific goals, financial goals or forecasted timelines.  In the event that the Company shall discharge the Employee pursuant to this Section 4(c), 
the Company shall not have any further obligation or liability under this Agreement, except that the Company shall pay to the Employee:  (i) any 
portion of the Employee’s Base Salary for the period up to the date of termination that has been earned but remains unpaid; and (ii) any benefits 
that have accrued to the Employee under the terms of the employee benefit plans of the Company, which benefits shall be paid in accordance with 
the terms of those plans.  

(d)                                  Other Termination by the Company.   The Company may terminate the employment of the Employee for any 

reason other than one specified in Section 4(b) or 4(c) hereof immediately upon written notice to the Employee, in which event the Employee shall 
be entitled to receive:  (i) any portion of the Employee’s Base Salary for the period up to the date of termination that has been earned but remains 
unpaid; (ii) any benefits that have accrued to the Employee under the terms of any employee benefit plans of the Company, which benefits shall 
be paid in accordance with the terms of those plans; and (iii) subject to the satisfaction of the provisions of Section 4(g) and the compliance by the 
Employee with all terms and provisions of  

3  

   
   
   
   
 
this Agreement that survive the termination of the Employee’s employment by the Company, (A) the Employee’s Base Salary for a period of nine 
months, less applicable taxes and withholdings, payable in accordance with the Company’s regular payroll practices, with an accelerated payment 
of any balance upon the occurrence of a Change in Control; provided, however, that if such termination of employment shall occur within three 
months before or within twelve months after the occurrence of a Change in Control (such period being referred to herein as the “Change of 
Control Period”), the severance payable to the Employee shall be increased to an amount equal to the Employee’s Base Salary for a period of 
eighteen months and be payable in a single lump sum payment, less applicable taxes and withholdings; (B) payment or reimbursement (upon 
presentation of proof of payment) of the Employee’s medical insurance premiums at the same level as was in effect on the termination date for a 
period of nine months, which period shall increase to eighteen months if such termination of employment shall occur within the Change in Control 
Period; and (C) if such termination shall occur within the Change in Control Period, an amount equal to the Employee’s Target Bonus for the year 
in which such employment termination shall occur prorated based on the relative number of days in such year during which the Employee was 
employed by the Company and/or its successor in the Change in Control, payable in a single lump sum payment, less applicable taxes and 
withholdings.  Any severance payments and lump sum payments due hereunder shall commence as soon as administratively feasible within 60 
days after the date of the Employee’s termination of employment provided the Employee has timely executed and returned the Release referred to 
in Section 4(g) and, if a revocation period is applicable, the Employee has not revoked the Release; provided, however, that if the 60-day period 
begins in one calendar year and ends in a second calendar year, the severance payments shall begin to be paid in the second calendar year.  On the 
date that severance payments commence, the Company will pay the Employee in a single lump sum payment, less applicable taxes and 
withholding, the severance payments that the Employee would have received on or prior to such date but for the delay imposed by the 
immediately preceding sentence, with the balance of the severance payments to be paid as originally scheduled.  

(e)                                   Termination by the Employee for Good Reason.   The Employee may terminate the Employee’s employment by 

providing written notice to the Company of a breach constituting Good Reason.  “Good Reason” shall be deemed to exist with respect to any 
termination of employment by the Employee for any of the following reasons:  (i) a reassignment of the Employee to a location outside the 
Greater Philadelphia area; (ii) any material failure by the Company to comply with any material term of this Agreement; (iii) the demotion of the 
Employee to a lesser position than described in Section 1 hereof or a substantial diminution of the Employee’s authority, duties or responsibilities 
as in effect on the date of this Agreement or as hereafter increased; or (iv) a material diminution of the Executive’s Base Salary and benefits, in 
the aggregate, unless such reduction is part of a Company-wide reduction in compensation and/or benefits for all of its senior executives.  If the 
Employee shall terminate the Employee’s employment hereunder for Good Reason, the Employee shall be entitled to receive the same payments 
and benefits on the same terms and conditions as would be applicable upon a termination of the Employee’s employment by the Company without 
Cause, as provided in Section 4(d) and subject to the satisfaction of the other provisions of this Section 4(e).  The Employee may not resign with 
Good Reason pursuant to this Section 4(e), and shall not be considered to have done so for any purpose of this Agreement, unless (A) the 
Employee, within 60 days after the initial existence of the act or failure to act by the Company that constitutes  

4  

   
   
   
 
“Good Reason” within the meaning of this Agreement, provides the Company with written notice that describes, in particular detail, the act or 
failure to act that the Employee believes to constitute “Good Reason” and identifies the particular clause of this Section 4(e) that the Employee 
contends is applicable to such act or failure to act; (B) the Company, within 30 days after its receipt of such notice, fails or refuses to rescind such 
act or remedy such failure to act so as to eliminate “Good Reason” for the termination by the Employee of the Employee’s employment 
relationship with the Company, and (C) the Employee actually resigns from the employ of the Company on or before that date that is six calendar 
months after the initial existence of the act or failure to act by the Company that constitutes “Good Reason.”  If the requirements of the preceding 
sentence are not fully satisfied on a timely basis, then the resignation by the Employee from the employ of the Company shall not be deemed to 
have been for “Good Reason,” the Employee shall not be entitled to any of the benefits to which the Employee would have been entitled if the 
Employee had resigned from the employ of the Company for “Good Reason,” and the Company shall not be required to pay any amount or 
provide any benefit that would otherwise have been due to the Employee under this Section 4(e) had the Employee resigned with “Good Reason.”  

(f)                                    Other Termination by the Employee.   The Employee may terminate the Employee’s employment for any reason 

other than one specified in Section 4(e) upon at least 30 days’ prior written notice to the Company, which notice shall specify the effective date of 
the termination.  In the event the Employee shall terminate the Employee’s employment pursuant to this Section 4(f), the Company shall not have 
any further obligation or liability under this Agreement, except that the Company shall pay to the Employee:  (i) any portion of the Employee’s 
Base Salary for the period up to the date of termination that has been earned but remains unpaid; and (ii) any benefits that have accrued to the 
Employee under the terms of the employee benefit plans of the Company, which benefits shall be paid in accordance with the terms of those plans. 

(g)                                  Execution of Release.  The Employee shall not be entitled to any payments or benefits under Sections 4(d) or 4

(e) unless the Employee executes and does not revoke a Release and Agreement (the “Release”), as drafted at the time of the Employee’s 
termination of employment, including, but not limited to:  

(i)                                      an unconditional release of all rights to any claims, charges, complaints, grievances, known or unknown to 
the Employee, against the Company, its affiliates or assigns, through the date of the Employee’s termination from employment other than post-
termination payments and benefits pursuant to this Agreement;  

grievances against the Company, its affiliates, or assigns;  

(ii)                                   a representation and warranty that the Employee has not filed or assigned any claims, charges, complaints, or 

to return any such confidential information and property to the Company upon execution of the Release;  

(iii)                                an agreement not to use, disclose or make copies of any confidential information of the Company, as well as 

5  

   
   
   
   
   
   
   
 
of employment;  

(iv)                               a mutual agreement to maintain the confidentiality of the Release or disclose the reasons for any termination 

(v)                                  an agreement not to disparage the Company or its officers, directors, stockholders, products or business; and  

any portion of this Agreement or the Release.  

(vi)                               an agreement to indemnify the Company, or its affiliates or assigns, in the event that the Employee breaches 

Notwithstanding any provision of this Agreement to the contrary, in no event shall the timing of the Employee’s execution of the Release, directly 
or indirectly, result in the Employee designating the calendar year of payment, and if a payment that is subject to execution of the Release could 
be made in more than one taxable year, payment shall be made in the later taxable year.  

(h)                                  Definition of Change in Control.   As used in this Agreement, the term “Change in Control” means:  

(i)                                      any merger or consolidation in which voting securities of the Company possessing more than 50% of the total 

combined voting power of the Company’s outstanding securities are transferred to a person or persons different from the person holding those 
securities immediately prior to such transaction and the composition of the Board following such transaction is such that the directors of the 
Company prior to the transaction constitute less than 50% of the Board membership following the transaction;  

(ii)                                   any acquisition, directly or indirectly, by a person or related group of persons (other than the Company or a 

person that directly or indirectly controls, is controlled by, or is under common control with, the Company) of beneficial ownership of voting 
securities of the Company possessing more than 50% of the total combined voting power of the Company’s outstanding securities; provided, 
however, that, no Change in Control shall be deemed to occur by reason of the acquisition of shares of the Company’s capital stock by an investor 
or group of investors in the Company in a capital-raising transaction; or  

the Company; or  

(iii)                                any sale, transfer, exclusive worldwide license or other disposition of all or substantially all of the assets of 

(iv)                               within any 24-month period beginning on or after the date hereof, the persons who were directors of the 

Company immediately before the beginning of such period (the “Incumbent Directors”) shall cease (for any reason other than death) to constitute 
at least a majority of the Board of Directors of the Company or the board of directors of any successor to the Company, provided that any director 
who was not a director as of the date hereof shall be deemed to be an Incumbent Director if such director was elected to the Board by, or on the 
recommendation of or with the approval of, at least two-thirds of the directors who then qualified as Incumbent Directors either actually or by 
prior operation of this Section 4(h)(iv), unless such election, recommendation or approval was the result of an actual or threatened contested 
election of directors pursuant to Regulation 14A under the Securities Exchange Act of 1934 or any successor provision.

(i)                                     Base Salary Continuation.  The Base Salary continuation set forth in Sections 4(d) and (e) above shall be intended 
either (i) to satisfy the safe harbor set forth in the regulations issued under section 409A of the Internal Revenue Code of 1986, as amended (the 
“Code”) (Treas. Regs. 1.409A-1(n)(2)(ii)) or (ii) be treated as a Short-term Deferral as that term is defined under Code section 409A (Treas. Regs. 
1.409A-1(b)(4)).  To the extent such continuation payments exceed the applicable safe harbor amount or do not constitute a Short-term Deferral, 
the excess amount shall be treated as deferred compensation under Code section 409A and as such shall be payable pursuant to the following 
schedule: such excess amount shall be paid via standard payroll in periodic installments in accordance with the Company’s usual practice for its 
senior executives.  Solely for purposes of Code section 409A, each installment payment is considered a separate payment.  Notwithstanding any 
provision in this Agreement to the contrary, in the event that the Employee is a “specified employee” as defined in Section 409A, any continuation 
payment, continuation benefits or other amounts payable under this Agreement that would be subject to the special rule regarding payments to 
“specified employees” under Section 409A(a)(2)(B) of the Code shall not be paid before the expiration of a period of six months following the 
date of the Employee’s termination of employment or before the date of the Employee’s death, if earlier.  

(j)                                     Parachute Provisions.   Notwithstanding any provisions of this Agreement to the contrary:  

(i)                                      If any of the payments or benefits received or to be received by the Employee in connection with the 

Employee’s termination of employment in respect of a Change in Control, whether pursuant to the terms of this Agreement or any other plan, 
arrangement or agreement with the Company (all such payments and benefits, being hereinafter referred to as the “Total Payments”), would be 
subject to the excise tax (the “Excise Tax”) imposed under Section 4999 of the Code, the Employee shall receive the Total Payments and be 
responsible for the Excise Tax; provided, however that the Employee shall not receive the Total Payments and the Total Payments shall be 
reduced to the Safe Harbor Amount (defined below) if (A) the net amount of such Total Payments, as so reduced to the Safe Harbor Amount (and 
after subtracting the net amount of federal, state and local income taxes on such reduced Total Payments) is greater than or equal to (B) the net 
amount of such Total Payment without such reduction (but after subtracting the net amount of federal, state and local income taxes on such Total 
Payments and the amount of Excise Tax to which the Employee would be subject in respect of such unreduced Total Payments).  The “Safe 
Harbor Amount” is the amount to which the Total Payments would hypothetically have to be reduced so that no portion of the Total Payments 
would be subject to the Excise Tax.  

(ii)                                   For purposes of determining whether any of the Total Payments will be subject to the Excise Tax and the 

amount of such Excise Tax, (A) all of the Total Payments shall be treated as “parachute payments” (within the meaning of Section 280G(b)(2) of 
the Code) unless, in the opinion of tax counsel (“Tax Counsel”) selected by the accounting firm that was, immediately prior to the Change in 
Control, the Company’s independent auditor (the “Auditor”), such payments or benefits (in whole or in part) do not constitute parachute 
payments, including by reason of Section 280G(b)(4)(A) of the Code, (B) all “excess parachute payments” within the meaning of Section 280G(b)
(1) of the Code shall be treated as subject to the Excise Tax unless, in the opinion of Tax Counsel, such excess parachute payments (in whole or in 
part)  

7  

   
   
   
   
   
 
represent reasonable compensation for services actually rendered (within the meaning of Section 280G(b)(4)(B) of the Code) in excess of the base 
amount (within the meaning of Section 280G(b)(3) of the Code) allocable to such reasonable compensation, or are otherwise not subject to the 
Excise Tax, and (C) the value of any noncash benefits or any deferred payment or benefit shall be determined by the Auditor in accordance with 
the principles of Sections 280G(d)(3) and (4) of the Code.  If the Auditor is prohibited by applicable law or regulation from performing the duties 
assigned to it hereunder, then a different auditor, acceptable to both the Company and Employee, shall be selected.  The fees and expenses of Tax 
Counsel and the Auditor shall be paid by the Company.  

(iii)                                In the event it is determined that the Safe Harbor Amount is payable to Employee, then the severance 
payments provided under this Agreement that are cash shall first be reduced on a pro rata basis, and the non-cash severance payments shall 
thereafter be reduced on a pro rata basis, to the extent necessary so that no portion of the Total Payments is subject to the Excise Tax.  

5.                                       Non-Disclosure and Non-Competition.  

(a)                                  Non-Disclosure.   The Employee acknowledges that in the course of performing services for the Company, the 

Employee will obtain knowledge of the Company’s business plans, products, processes, software, know-how, trade secrets, formulas, methods, 
models, prototypes, discoveries, inventions, improvements, disclosures, names and positions of employees and/or other proprietary and/or 
confidential information (collectively the “Confidential Information”).  The Employee agrees to keep the Confidential Information secret and 
confidential and not to publish, disclose or divulge to any other party, and the Employee agrees not to use any of the Confidential Information for 
the Employee’s own benefit or to the detriment of the Company without the prior written consent of the Company, whether or not such 
Confidential Information was discovered or developed by the Employee.  The Employee also agrees not to divulge, publish or use any proprietary 
and/or confidential information of others that the Company is obligated to maintain in confidence.  

(b)                                  Non-Competition.   The Employee agrees that, during the Employee’s employment by the Company hereunder and 

for an additional period of twelve months after the termination of the Employee’s employment hereunder, neither the Employee nor any 
corporation or other entity in which the Employee may be interested as a partner, trustee, director, officer, employee, agent, shareholder, lender of 
money or guarantor, or for which the Employee performs services in any capacity (including as a consultant or independent contractor) shall at 
any time during such period (i) be engaged, directly or indirectly, in any Competitive Business (as that term is hereinafter defined) or (ii) solicit, 
hire, contract for services or otherwise employ, directly or indirectly, any of the employees of the Company.  For purposes of this Section 5(b), the 
term “Competitive Business” shall mean any firm or business organization that competes with the Company in the development and/or 
commercialization of drugs that prevent or treat partial complex seizures, post-traumatic stress disorder or fragile-x syndrome or any other 
Ganaxolone-related technology, product or service being developed, manufactured, marketed, distributed or planned in writing by the Company at 
the time of termination of the Employee’s employment with the Company. The foregoing prohibition shall not prevent any employment or 
engagement of the Employee, after termination of employment with the Company, by any  

8  

   
   
   
   
   
   
 
company or business organization not substantially engaged in a Competitive Business as long as the activities of any such employment or 
engagement, in any capacity, do not involve work on matters related to any product or service being developed, manufactured, marketed, 
distributed or planned in writing by the Company at the time of termination of Employee’s employment with the Company.  The Employee’s 
ownership of no more than 5% of the outstanding voting stock of a publicly traded company shall not constitute a violation of this Section 5(b).  
The Employee is entering into this covenant not to compete to continue the Employee’s undertaking in the Prior Agreement and in consideration 
of the additional agreements of the Company in this Agreement, including but not limited to the rights of the Employee set forth in Sections 4
(d) and 4(e).  

6.                                       Inventions and Discoveries.  

(a)                                  Disclosure.   The Employee shall promptly and fully disclose to the Company, with all necessary detail, all 

developments, know-how, discoveries, inventions, improvements, concepts, ideas, formulae, processes and methods (whether copyrightable, 
patentable or otherwise) made, received, conceived, acquired or written by the Employee (whether or not at the request or upon the suggestion of 
the Company, solely or jointly with others), during the period of the Employee’s employment with the Company that (i) result from, arise out of, 
or relate to any work, assignment or task performed by the Employee on behalf of the Company, whether undertaken voluntarily or assigned to the 
Employee within the scope of the Employee’s responsibilities to the Company, or (ii) were developed using the Company’s facilities or other 
resources or in Company time, or (iii) result from the Employee’s use or knowledge of the Company’s Confidential Information, or (iv) relate to 
the Company’s business or any of the products or services being developed, manufactured or sold by the Company or that may be used in relation 
therewith (collectively referred to as “Inventions”).  The Employee hereby acknowledges that all original works of authorship that are made by the 
Employee (solely or jointly with others) within the above terms and that are protectable by copyright are “works made for hire,” as that term is 
defined in the United States Copyright Act.  The Employee understands and hereby agrees that the decision whether or not to commercialize or 
market any Invention developed by the Employee solely or jointly with others is within the Company’s sole discretion and for the Company’s sole 
benefit and that no royalty shall be due to the Employee as a result of the Company’s efforts to commercialize or market any such Invention.  

(b)                                  Assignment and Transfer.   The Employee agrees to assign and transfer to the Company all of the Employee’s right, 

title and interest in and to the Inventions, and the Employee further agrees to deliver to the Company any and all drawings, notes, specifications 
and data relating to the Inventions, and to sign, acknowledge and deliver all such further papers, including applications for and assignments of 
copyrights and patents, and all renewals thereof, as may be necessary to obtain copyrights and patents for any Inventions in any and all countries 
and to vest title thereto in the Company and its successors and assigns and to otherwise protect the Company’s interests therein.  The Employee 
shall not charge the Company for time spent in complying with these obligations.  If the Company is unable because of the Employee’s mental or 
physical incapacity or for any other reason to secure the Employee’s signature to apply for or to pursue any application for any United States or 
foreign patents or copyright registrations covering Inventions or original works of authorship assigned to the Company as above, then the 
Employee hereby irrevocably designates and appoints the Company and its duly authorized  

9  

   
   
   
   
   
 
officers and agents as the Employee’s agent and attorney in fact, to act for and in the Employee’s behalf and stead to execute and file any such 
applications and to do all other lawfully permitted acts to further the prosecution and issuance of letters patent or copyright registrations thereon 
with the same legal force and effect as if executed by the Employee.  

(c)                                   Company Documentation.  The Employee shall hold in a fiduciary capacity for the benefit of the Company all 

documentation, disks, programs, data, records, drawings, manuals, reports, sketches, blueprints, letters, notes, notebooks and all other writings, 
electronic data, graphics and tangible information and materials of a secret, confidential or proprietary information nature relating to the Company 
or the Company’s business that are in the possession or under the control of the Employee.  The Employee agrees that in connection with any 
research, development or other services performed for the Company, the Employee will maintain careful, adequate and contemporaneous written 
records of all Inventions, which records shall be the property of the Company.  

7.                                       Injunctive Relief.   The Employee acknowledges that the Employee’s compliance with the agreements in Sections 5 and 6 

hereof is necessary to protect the good will and other proprietary interests of the Company and that the Employee is one of the principal 
executives of the Company and conversant with its affairs, its trade secrets and other proprietary information.  The Employee acknowledges that a 
breach of any of the Employee’s agreements in Sections 5 and 6 hereof will result in irreparable and continuing damage to the Company for which 
there will be no adequate remedy at law; and the Employee agrees that in the event of any breach of the aforesaid agreements, the Company and 
its successors and assigns shall be entitled to injunctive relief and to such other and further relief as may be proper.  

8.                                       Full Agreement.   This Agreement amends, restates and supersedes the Prior Agreement and all other consulting and 
employment arrangements between the Employee and the Company, but shall not supersede any existing confidentiality, nondisclosure, invention 
assignment or non-compete agreement between the Employee and the Company.  Except as set forth in the preceding sentence, this Agreement 
constitutes the entire agreement of the parties concerning its subject matter and supersedes all other oral or written understandings, discussions, 
and agreements, and may be modified only in a writing signed by both parties.  The parties acknowledge that they have read and fully understand 
the contents of this Agreement and execute it after having an opportunity to consult with legal counsel.  

9.                                       Amendments.   Any amendment to this Agreement shall be made in writing and signed by the parties hereto.  

10.                                Enforceability.   If any provision of this Agreement shall be invalid or unenforceable, in whole or in part, then such provision 

shall be deemed to be modified or restricted to the extent and in the manner necessary to render the same valid and enforceable, or shall be 
deemed excised from this Agreement, as the case may require, and this Agreement shall be construed and enforced to the maximum extent 
permitted by law as if such provision had been originally incorporated herein as so modified or restricted or as if such provision had not been 
originally incorporated herein, as the case may be.

11.                                Construction.   This Agreement shall be construed and interpreted in accordance with the internal laws of the Commonwealth 

of Pennsylvania.  

12.                                Assignment.  

(a)                                  By the Company.   The rights and obligations of the Company under this Agreement shall inure to the benefit of, and 
shall be binding upon, the successors and assigns of the Company.  This Agreement may be assigned by the Company without the consent of the 
Employee.  

(b)                                  By the Employee.   This Agreement and the obligations created hereunder may not be assigned by the Employee, but 

all rights of the Employee hereunder shall inure to the benefit of and be enforceable by the Employee’s heirs, devisees, legatees, executors, 
administrators and personal representatives.  

13.                                Notices.   All notices required or permitted to be given hereunder shall be in writing and shall be deemed to have been given 

when mailed by certified mail, return receipt requested, or delivered by a national overnight delivery service addressed to the intended recipient as 
follows:  

If to the Company:  

Marinus Pharmaceuticals, Inc.  
Three Radnor Corporate Center  
100 Matsonford Road, Suite 304  
Radnor, PA 19087  
Attention:  Chief Executive Officer  

If to the Employee, to address stated on the signature page to this Agreement.  

Any party may from time to time change its address for the purpose of notices to that party by a similar notice specifying a new address, but no 
such change shall be deemed to have been given until it is actually received by the party sought to be charged with its contents.  

14.                                Waivers.   No claim or right arising out of a breach or default under this Agreement shall be discharged in whole or in part by a 

waiver of that claim or right unless the waiver is supported by consideration and is in writing and executed by the aggrieved party hereto or such 
party’s duly authorized agent.  A waiver by any party hereto of a breach or default by the other party hereto of any provision of this Agreement 
shall not be deemed a waiver of future compliance therewith, and such provisions shall remain in full force and effect.  

15.                                Section 409A.   It is intended that this Agreement be drafted and administered in compliance with section 409A of the Code, 

including, but not limited to, any future amendments to Code section 409A, and any other Internal Revenue Service or other governmental rulings 
or interpretations (together, “Section 409A”) issued pursuant to Section 409A so as not to subject the Employee to payment of interest or any 
additional tax under Code section 409A.  The parties intend for any payments under this Agreement to either satisfy the requirements of 
Section 409A  

11  

   
   
   
   
   
   
   
   
   
   
   
   
 
or to be exempt from the application of Section 409A, and this Agreement shall be construed and interpreted accordingly.  In furtherance thereof, 
if payment or provision of any amount or benefit hereunder that is subject to Section 409A at the time specified herein would subject such amount 
or benefit to any additional tax under Section 409A, the payment or provision of such amount or benefit shall be postponed to the earliest 
commencement date on which the payment or provision of such amount or benefit could be made without incurring such additional tax.  In 
addition, to the extent that any Internal Revenue Service guidance issued under Section 409A would result in the Employee being subject to the 
payment of interest or any additional tax under Section 409A, the parties agree, to the extent reasonably possible, to amend this Agreement in 
order to avoid the imposition of any such interest or additional tax under Section 409A, which amendment shall have the minimum economic 
effect necessary and be reasonably determined in good faith by the Company and the Employee.  

16.                                Survival of Covenants.   The provisions of Sections 4, 5, 6 and 7 hereof shall survive the termination of this Agreement.  

Furthermore, each other provision of this Agreement that, by its terms, is intended to continue beyond the termination of the Employee’s 
employment shall continue in effect thereafter.

2014 EQUITY INCENTIVE PLAN  

EXHIBIT 10.13 

The purpose of the Marinus Pharmaceuticals, Inc. 2014 Equity Incentive Plan is to provide (i) designated employees of Marinus 
Pharmaceuticals, Inc. (the “Company”) and its parents and subsidiaries, (ii) certain consultants and advisors who perform services for the 
Company or its parents or subsidiaries and (iii) non-employee members of the Board of Directors of the Company (the “Board”) with the 
opportunity to receive grants of incentive stock options, nonqualified stock options, stock awards, stock units, stock appreciation rights and other 
equity-based awards.  The Company believes that this Plan will encourage the participants to contribute materially to the growth of the Company, 
thereby benefitting the Company’s stockholders, and will align the economic interests of the participants with those of the stockholders.  

1.                                       Administration and Delegation .  

(a)                                  Committee .   This Plan shall be administered by a committee consisting of two or more members of the Board, which shall 

consist of “outside directors” as defined under section 162(m) of the Internal Revenue Code of 1986, as amended (the “Code”), and related 
Treasury regulations, “non-employee directors” as defined under Rule 16b-3 under the Securities Exchange Act of 1934, as amended (the 
“Exchange Act”) and, when applicable, by “independent directors” as defined by the rules of any national securities exchange (the “Exchange”) 
upon which shares of the Company’s capital stock shall be listed.  However, the Board may ratify or approve any grants as it deems appropriate, 
and the Board shall approve and administer all grants made to non-employee directors.  The committee may delegate authority to one or more 
subcommittees as it deems appropriate.  To the extent that a committee or subcommittee administers this Plan, references in this Plan to the 
“Board” shall be deemed to refer to the committee or subcommittee.  

(b)                                  Board Authority .  The Board shall have the sole authority to (i) determine the individuals to whom grants shall be made 

under this Plan, (ii) determine the type, size and terms of the grants to be made to each such individual, (iii) determine the time when the grants 
will be made and the duration of any applicable exercise or restriction period, including the criteria for exercisability and the acceleration of 
exercisability, (iv) amend the terms of any previously issued grant, and (v) deal with any other matters arising under this Plan.  

(c)                                   Board Determinations .   The Board shall have full power and authority to administer and interpret this Plan, to make factual 

determinations and to adopt or amend such rules, regulations, agreements and instruments for implementing this Plan and for the conduct of its 
business as it deems necessary or advisable, in its sole discretion.  The Board’s interpretations of this Plan and all determinations made by the 
Board pursuant to the powers vested in it hereunder shall be conclusive and binding on all persons having any interest in this Plan or in any 
awards granted hereunder.  All powers of the Board shall be executed in its sole discretion, in the best interest of the Company, not as a fiduciary, 
and in keeping with the objectives of this Plan and need not be uniform as to similarly situated individuals.  

  
   
   
   
   
   
   
   
 
(d)                                  Delegation to Officers .   To the extent permitted by applicable law, the Board may delegate to one or more officers of the 
Company the power to grant Options and other Grants that constitute rights under Delaware law (subject to any limitations under this Plan) to 
employees or officers of the Company and to exercise such other powers under this Plan as the Board may determine, provided that the Board 
shall fix the terms of such Grants to be granted by such officers (including the exercise price of such Grants, which may include a formula by 
which the exercise price will be determined) and the maximum number of shares subject to such Grants that the officers may grant; provided 
further, however, that no officer shall be authorized to grant such Grants to any “executive officer” of the Company (as defined by Rule 3b-7 
under the Exchange Act) or to any “officer” of the Company (as defined by Rule 16a-1 under the Exchange Act).  Notwithstanding anything to the 
contrary set forth above, the Board may not delegate authority under this Section 1(d) to grant Stock Awards, unless Delaware law then permits 
such delegation.  

2.                                       Grants .   Awards under this Plan may consist of grants of incentive stock options as described in Section 5 (“Incentive Stock 
Options”), nonqualified stock options as described in Section 5 (“Nonqualified Stock Options”) (Incentive Stock Options and Nonqualified Stock 
Options are collectively referred to as “Options”), stock awards as described in Section 6 (“Stock Awards”), stock units as described in Section 7 
(“Stock Units”), stock appreciation rights as described in Section 8 (“SARs”), and other equity-based awards as described in Section 9 (“Other 
Equity Awards”), the foregoing sometimes referred to herein collectively as “Grants” and individually as a “Grant.”  All Grants shall be subject to 
the terms and conditions set forth herein and to such other terms and conditions consistent with this Plan as the Board deems appropriate and as 
are specified in writing by the Board to the individual in a grant instrument or an amendment to the grant instrument (the “Grant Instrument”).  All 
Grants shall be made conditional upon the acknowledgement of the Grantee (as defined in Section 4(b)), in writing or by acceptance of the Grant, 
that all decisions and determinations of the Board shall be final and binding on the Grantee, his or her beneficiaries and any other person having or 
claiming an interest under such Grant.  Grants under a particular Section of this Plan need not be uniform as among the grantees.  

3.                                       Shares Subject to This Plan .  

(a)                                  Shares Authorized .   Subject to adjustment as described below, the aggregate number of shares of common stock of the 

Company (“Company Stock”) that may be issued pursuant to Grants under this Plan is 700,000 shares, each of which may be issued under this 
Plan as an Incentive Stock Option.  In addition, the number of shares of Company Stock that may be issued pursuant to Grants under this Plan and 
the number of shares of Company Stock that may be issued under this Plan as Incentive Stock Options shall be increased annually on January 1 of 
each year, commencing January 1, 2015, until the expiration of this Plan by a number equal to the lesser of (i) 1,120,000 shares of Company 
Stock, (ii) an amount equal to 4% of the total number of shares of the Company’s capital stock outstanding on such date, calculated on a common-
equivalent basis, or (iii) an amount determined by the Board.  Shares issued under this Plan may be authorized but unissued shares of Company 
Stock or reacquired shares of Company Stock, including shares purchased by the Company on the open market for purposes of this Plan.  

2  

   
   
   
   
   
 
(b)                                  Individual Limits .  The maximum aggregate number of shares of Company Stock that shall be subject to Grants made under 

this Plan to any individual during any calendar year shall be 700,000 shares.  

(c)                                   Share Counting .   If and to the extent Options or SARs granted under this Plan terminate, expire, or are canceled, forfeited, 
exchanged or surrendered without having been exercised or if any Stock Awards, Stock Units or Other Equity Awards are forfeited, the shares 
subject to such Grants shall again be available for purposes of this Plan.  

(d)                                  Adjustments .  If there is any change in the number or kind of shares of Company Stock outstanding (i) by reason of a stock 
dividend, spinoff, recapitalization, stock split, or combination or exchange of shares, (ii) by reason of a merger, reorganization or consolidation, 
(iii) by reason of a reclassification or change in par value, or (iv) by reason of any other extraordinary or unusual event affecting the outstanding 
Company Stock as a class without the Company’s receipt of consideration, or if the value of outstanding shares of Company Stock is substantially 
reduced as a result of a spinoff or the Company’s payment of an extraordinary dividend or distribution, the maximum number of shares of 
Company Stock available for issuance under this Plan, the maximum number of shares of Company Stock for which any individual may receive 
Grants in any year, the kind and number of shares covered by outstanding Grants, the kind and number of shares issued and to be issued under this 
Plan, and the price per share or the applicable market value of such Grants shall be equitably adjusted by the Board to reflect any increase or 
decrease in the number of, or change in the kind or value of, issued shares of Company Stock to preclude, to the extent practicable, the 
enlargement or dilution of rights and benefits under such Grants; provided, however, that any fractional shares resulting from such adjustment 
shall be eliminated.  In addition, in the event of a Change of Control of the Company (as defined in Section 12(a)), the provisions of Section 13 of 
this Plan shall apply.  Any adjustment to outstanding Grants shall be consistent with section 409A and section 424 of the Code, to the extent 
applicable.  Any adjustments determined by the Board shall be final, binding and conclusive.  

4.                                       Eligibility for Participation .  

(a)                                  Eligible Persons .  All employees of the Company and its parents or subsidiaries (“Employees”), including Employees who are 

officers or members of the Board, and members of the Board who are not Employees (“Non-Employee Directors”) shall be eligible to participate 
in this Plan.  Consultants and advisors, as such terms are defined and interpreted for purposes of Form S-8 under the Securities Act of 1933, as 
amended (the “Securities Act”) (or any successor form or rule) who perform services for the Company or any of its parents or subsidiaries (“Key 
Advisors”) shall be eligible to participate in this Plan.  

(b)                                  Selection of Grantees .   The Board shall select the Employees, Non-Employee Directors and Key Advisors to receive Grants 

and shall determine the number of shares of Company Stock subject to a particular Grant in such manner as the Board determines.  Employees, 
Key Advisors and Non-Employee Directors who receive Grants under this Plan shall hereinafter be referred to as “Grantees.”

5.                                       Options .  The Board may grant Options to Employees, Non-Employee Directors, and Key Advisors upon such terms as the 

Board deems appropriate.  The following provisions are applicable to Options:  

(a)                                  Number of Shares .   The Board shall determine the number of shares of Company Stock that will be subject to each Grant of 

Options to Employees, Non-Employee Directors and Key Advisors.  

(b)                                  Type of Option and Price .  

(i)                                      The Board may grant Incentive Stock Options that are intended to qualify as “incentive stock options” within the 
meaning of section 422 of the Code or Nonqualified Stock Options that are not intended so to qualify or any combination of Incentive Stock 
Options and Nonqualified Stock Options, all in accordance with the terms and conditions set forth herein.  Incentive Stock Options may be 
granted only to employees of the Company or its parents or subsidiaries, as defined in section 424 of the Code.  Nonqualified Stock Options may 
be granted to Employees, Non-Employee Directors and Key Advisors.  

(ii)                                   The purchase price (the “Exercise Price”) of Company Stock subject to an Option shall be determined by the Board 

and shall be equal to or greater than the Fair Market Value (as defined below) of a share of Company Stock on the date the Option is granted; 
provided, however, that an Incentive Stock Option may not be granted to an Employee who, at the time of grant, owns stock possessing more than 
10% of the total combined voting power of all classes of stock of the Company or any parent or subsidiary of the Company, unless the Exercise 
Price per share is not less than 110% of the Fair Market Value of Company Stock on the date of grant.  

(iii)                                If the Company Stock is publicly traded, then the Fair Market Value per share shall be determined as follows:  (x) if 

the principal trading market for the Company Stock is an Exchange, the last reported sale price thereof on the relevant date or (if there were no 
trades on that date) the latest preceding date upon which a sale was reported, or (y) if the Company Stock is not principally traded on an 
Exchange, the mean between the last reported “bid” and “asked” prices of Company Stock on the relevant date, as reported on the Exchange or, if 
not so reported, as reported by the over-the-counter quotation system on which the Company Stock is then quoted or as reported in a customary 
financial reporting service, as applicable and as the Board determines.  If the Company Stock is not publicly traded or, if publicly traded, is not 
subject to reported transactions or “bid” or “asked” quotations as set forth above, the Fair Market Value per share shall be as determined by the 
Board.  

(c)                                   Option Term .  The Board shall determine the term of each Option.  The term of any Option shall not exceed ten years from 

the date of grant.  However, an Incentive Stock Option that is granted to an Employee who, at the time of grant, owns stock possessing more than 
10% of the total combined voting power of all classes of stock of the Company, or any parent or subsidiary of the Company, may not have a term 
that exceeds five years from the date of grant.

(d)                                  Exercisability of Options .  

(i)                                      Options shall become exercisable in accordance with such terms and conditions, consistent with this Plan, as may be 
determined by the Board and specified in the Grant Instrument.  The Board may accelerate the exercisability of any or all outstanding Options at 
any time for any reason.  

(ii)                                   The Board may provide in a Grant Instrument that the Grantee may elect to exercise part or all of an Option before it 

otherwise has become exercisable.  Any shares so purchased shall be restricted shares and shall be subject to a repurchase right in favor of the 
Company during a specified restriction period, with the repurchase price equal to the lesser of (i) the Exercise Price or (ii) the Fair Market Value 
of such shares at the time of repurchase, or such other restrictions as the Board deems appropriate.  

(e)                                   Grants to Non-Exempt Employees .   Notwithstanding the foregoing, unless expressly approved by the Board, Options 
granted to persons who are non-exempt employees under the Fair Labor Standards Act of 1938, as amended, (the “FLSA”) may not be exercisable 
for at least six months after the date of grant (except that such Options may become exercisable, as determined by the Board, upon the Grantee’s 
death, Disability (as defined in Section 5(f)(v)(C)) or Retirement (as defined in Section 5(f)(v)(E)), or upon a Change of Control or other 
circumstances permitted by applicable regulations).  

(f)                                    Termination of Employment, Disability or Death .  

(i)                                      Except as provided below, an Option may be exercised only while the Grantee is employed by, or providing service to, 

the Employer (as defined in Section 5(f)(v)(A)) as an Employee, Key Advisor or member of the Board.  In the event that a Grantee ceases to be 
employed by, or provide service to, the Employer for any reason other than Disability, death, Retirement or termination for Cause (as defined in 
Section 5(f)(v)(D)), except as otherwise provided by the Board, any Option that is otherwise exercisable by the Grantee shall terminate unless 
exercised within 90 days after the date on which the Grantee ceases to be employed by, or provide service to, the Employer (or within such other 
period of time as may be specified by the Board), but in any event no later than the date of expiration of the Option term.  Except as otherwise 
provided by the Board, any of the Grantee’s Options that are not otherwise exercisable as of the date on which the Grantee ceases to be employed 
by, or provide service to, the Employer shall terminate as of such date.  

(ii)                                   In the event the Grantee ceases to be employed by, or provide service to, the Employer on account of a termination for 
Cause by the Employer, any Option held by the Grantee shall terminate as of the date the Grantee ceases to be employed by, or provide service to, 
the Employer.  In addition, notwithstanding any other provisions of this Section 5, if the Board determines that the Grantee has engaged in 
conduct that constitutes Cause at any time while the Grantee is employed by, or providing service to, the Employer or after the Grantee’s 
termination of employment or service, any Option held by the Grantee shall immediately terminate, and the Grantee shall automatically forfeit all 
shares underlying any exercised portion of an Option for which the Company has not yet delivered the share certificates, upon refund by the 
Company of the Exercise Price paid by the Grantee for such shares.  Upon any exercise of an  

5  

   
   
   
   
   
   
   
   
 
Option, the Company may withhold delivery of share certificates pending resolution of an inquiry that could lead to a finding resulting in a 
forfeiture.  

(iii)                                In the event the Grantee ceases to be employed by, or provide service to, the Employer because of the Grantee’s 

Disability or Retirement, any Option that is otherwise exercisable by the Grantee shall terminate unless exercised within one year after the date on 
which the Grantee ceases to be employed by, or provide service to, the Employer (or within such other period of time as may be specified by the 
Board), but in any event no later than the date of expiration of the Option term.  Except as otherwise provided by the Board, any of the Grantee’s 
Options that are not otherwise exercisable as of the date on which the Grantee ceases to be employed by, or provide service to, the Employer shall 
terminate as of such date.  In the event that an Incentive Stock Option is exercised more than 90 days after Retirement, the Option shall lose its 
status as an Incentive Stock Option and shall be treated as a Nonqualified Stock Option.  

(iv)                               If the Grantee dies while employed by, or providing service to, the Employer or within 90 days after the date on which 
the Grantee ceases to be employed or provide service on account of a termination specified in Section 5(f)(i) above (or within such other period of 
time as may be specified by the Board), any Option that is otherwise exercisable by the Grantee shall terminate unless exercised within one year 
after the date on which the Grantee ceases to be employed by, or provide service to, the Employer (or within such other period of time as may be 
specified by the Board), but in any event no later than the date of expiration of the Option term.  Except as otherwise provided by the Board, any 
of the Grantee’s Options that are not otherwise exercisable as of the date on which the Grantee ceases to be employed by, or provide service to, 
the Employer shall terminate as of such date.  

(v)                                  For purposes of this Section 5(f) and Section 6:  

(A)                                The term “Employer” shall include the Company and its parent and subsidiary corporations, as determined by the 

Board.  

(B)                                “Employed by, or provide service to, the Employer” shall mean employment or service as an Employee, Key Advisor 

or member of the Board (so that, for purposes of exercising Options and satisfying conditions with respect to other Grants, a Grantee 
shall not be considered to have terminated employment or service until the Grantee ceases to be an Employee, Key Advisor or member of 
the Board), unless the Board determines otherwise.  

(C)                                “Disability” shall mean a Grantee’s becoming disabled within the meaning of section 22(e)(3) of the Code, within the 

meaning of the Employer’s long-term disability plan applicable to the Grantee, or as otherwise determined by the Board.  

(D)                                “Cause” shall mean, except to the extent specified otherwise by the Board, a finding by the Board that the Grantee 

(i) has breached his or her employment or service contract with the Employer in any material respect, (ii) has engaged in disloyalty to the 
Company, including, without limitation, fraud, embezzlement, theft, commission of a felony or proven dishonesty, (iii) has disclosed 
trade secrets or confidential information of the Employer to persons not entitled to receive such information, (iv) has breached any  

6  

   
   
   
   
   
   
   
   
   
 
written noncompetition or nonsolicitation agreement between the Grantee and the Employer or (v) has engaged in such other behavior 
detrimental to the interests of the Employer as the Board determines.  

(E)                                 “Retirement” shall mean a termination of employment by reason of an Employee’s retirement at or after the 
Employee’s earliest permissible retirement date pursuant to and in accordance with a regular retirement plan or the personnel practices of 
the Employer.  

(g)                                  Exercise of Options .   A Grantee may exercise an Option that has become exercisable, in whole or in part, by delivering a 
notice of exercise to the Company.  The Grantee shall pay the Exercise Price for an Option as specified by the Board (w) in cash, (x) with the 
approval of the Board, by delivering shares of Company Stock owned by the Grantee (including Company Stock acquired in connection with the 
exercise of an Option, subject to such restrictions as the Board deems appropriate) and having a Fair Market Value on the date of exercise equal to 
the Exercise Price or by attestation (on a form prescribed by the Board) to ownership of shares of Company Stock having a Fair Market Value on 
the date of exercise equal to the Exercise Price, (y) payment through a broker in accordance with procedures permitted by applicable regulations 
of the Board of Governors of the Federal Reserve System, or (z) by such other method as the Board may approve.  Shares of Company Stock used 
to exercise an Option shall have been held by the Grantee for the requisite period of time to avoid adverse accounting consequences to the 
Company with respect to the Option.  The Grantee shall pay the Exercise Price and the amount of any withholding tax due (pursuant to 
Section 10) at the time of exercise.  

(h)                                  Limits on Incentive Stock Options .  Each Incentive Stock Option shall provide that, if the aggregate Fair Market Value of the 

stock on the date of the grant with respect to which Incentive Stock Options are exercisable for the first time by a Grantee during any calendar 
year, under this Plan or any other stock option plan of the Company or a parent or subsidiary, exceeds $100,000, then the Option, as to the excess, 
shall be treated as a Nonqualified Stock Option.  An Incentive Stock Option shall not be granted to any person who is not an Employee of the 
Company or a parent or subsidiary (within the meaning of section 424(f) of the Code) of the Company.  

(i)                                     Limitation on Repricing .  If the Company Stock is listed on an Exchange, unless such action is approved by the Company’s 

stockholders, the Company may not (except as provided for under Section 3(d)): (A) amend any outstanding Option granted under this Plan to 
provide an exercise price per share that is lower than the then-current exercise price per share of such outstanding Option, (B) cancel any 
outstanding Option (whether or not granted under the Plan) and grant in substitution therefor new Grants under this Plan (other than adjustments 
made pursuant to Section 3(d)) covering the same or a different number of shares of Company Stock and having an exercise price per share lower 
than the then-current exercise price per share of the cancelled option, (C) cancel in exchange for a cash payment any outstanding Option with an 
exercise price per share above the then-current Fair Market Value, other than pursuant to Section 3(d), or (D) take any other action under this Plan 
that constitutes a “repricing” within the meaning of the rules of the Exchange.

6.                                       Stock Awards .  The Board may issue shares of Company Stock to an Employee, Non-Employee Director or Key Advisor 

under a Stock Award, upon such terms as the Board deems appropriate.  The following provisions are applicable to Stock Awards:  

(a)                                  General Requirements .  Shares of Company Stock issued or transferred pursuant to Stock Awards may be issued or 

transferred for cash consideration or for no cash consideration, and subject to restrictions or no restrictions, as determined by the Board.  The 
Board may, but shall not be required to, establish conditions under which restrictions on Stock Awards shall lapse over a period of time or 
according to such other criteria as the Board deems appropriate, including without limitation restrictions based on the achievement of specific 
performance goals.  The period of time during which the Stock Award will remain subject to restrictions will be designated in the Grant 
Instrument as the “Restriction Period.”  

(b)                                  Number of Shares .   The Board shall determine the number of shares of Company Stock to be issued or transferred pursuant 

to a Stock Award and the restrictions applicable to such shares.  

(c)                                   Requirement of Employment or Service .   Unless the Board determines otherwise, if the Grantee ceases to be employed by, 
or provide service to, the Employer (as defined in Section 5(f)(v)(A)) during a period designated in the Grant Instrument as the Restriction Period, 
or if other specified conditions are not met, the Stock Award shall terminate as to all shares covered by the Grant as to which the restrictions have 
not lapsed, and those shares of Company Stock must be immediately returned to the Company.  The Board may, however, provide for complete or 
partial exceptions to this requirement as it deems appropriate.  

(d)                                  Restrictions on Transfer and Legend on Stock Certificate .  During the Restriction Period, a Grantee may not sell, assign, 
transfer, pledge or otherwise dispose of the shares of the Stock Award except to a successor under Section 11(a).  Each certificate representing a 
Stock Award shall contain a legend giving appropriate notice of the restrictions in the Grant.  The Grantee shall be entitled to have the legend 
removed from the stock certificate covering the shares subject to restrictions when all restrictions on such shares have lapsed.  The Board may 
determine that the Company will not issue a certificate for a Stock Award until all restrictions on such shares have lapsed, or that the Company 
will retain possession of certificates for Stock Awards until all restrictions on such shares have lapsed.  

(e)                                   Right to Vote and to Receive Dividends .  Unless the Board determines otherwise, during the Restriction Period, the Grantee 
shall have the right to vote shares subject to Stock Awards and to receive any dividends or other distributions paid on such shares, subject to any 
restrictions deemed appropriate by the Board, including without limitation the achievement of specific performance goals.  

(f)                                    Lapse of Restrictions .  All restrictions imposed on Stock Awards shall lapse upon the expiration of the applicable Restriction 
Period and the satisfaction of all conditions imposed by the Board.  The Board may determine, as to any or all Stock Awards, that the restrictions 
shall lapse without regard to any Restriction Period.

7.                                       Stock Units .   The Board may grant Stock Units representing one or more shares of Company Stock to an Employee, Non-

Employee Director or Key Advisor, upon such terms and conditions as the Board deems appropriate, provided, however, that all such grants shall 
comply with section 409A of the Code.  The following provisions are applicable to Stock Units:  

(a)                                  Crediting of Units .   Each Stock Unit shall represent the right of the Grantee to receive an amount based on the value of a 

share of Company Stock, if specified conditions are met.  All Stock Units shall be credited to bookkeeping accounts established on the Company’s 
records for purposes of this Plan.  

(b)                                  Terms of Stock Units .   The Board may grant Stock Units that are payable if specified performance goals or other conditions 
are met, or under other circumstances.  Stock Units may be paid at the end of a specified performance period or other period, or payment may be 
deferred to a date authorized by the Board.  The Board shall determine the number of Stock Units to be granted and the requirements applicable to 
such Stock Units.  

(c)                                   Requirement of Employment or Service .   Unless the Board determines otherwise, if the Grantee ceases to be employed by, 

or provide service to, the Employer during a specified period, or if other conditions established by the Board are not met, the Grantee’s Stock 
Units shall be forfeited.  The Board may, however, provide for complete or partial exceptions to this requirement as it deems appropriate.  

(d)                                  Payment with Respect to Stock Units .   Payments with respect to Stock Units may be made in cash, in Company Stock, or in 

a combination of the two, as determined by the Board.  

8.                                       Stock Appreciation Rights .   The Board may grant SARs to an Employee, Non-Employee Director or Key Advisor separately 

or in tandem with any Option.  The following provisions are applicable to SARs:  

(a)                                  Base Amount .   The Board shall establish the base amount of the SAR at the time the SAR is granted.  The base amount of 

each SAR shall not be less than the Fair Market Value of a share of Company Stock on the date of Grant of the SAR.  

(b)                                  Tandem SARs .   In the case of tandem SARs, the number of SARs granted to a Grantee that shall be exercisable during a 

specified period shall not exceed the number of shares of Company Stock that the Grantee may purchase upon the exercise of the related Option 
during such period.  Upon the exercise of an Option, the SARs relating to the Company Stock covered by such Option shall terminate.  Upon the 
exercise of SARs, the related Option shall terminate to the extent of an equal number of shares of Company Stock.  

(c)                                   Exercisability .   An SAR shall be exercisable during the period specified by the Board in the Grant Instrument and shall be 
subject to such vesting and other restrictions as may be specified in the Grant Instrument.  The Board may accelerate the exercisability of any or 
all outstanding SARs at any time for any reason.  SARs may only be exercised while the Grantee is employed by, or providing service to, the 
Employer or during the applicable period after termination of employment or service as described in Section 5(f) above.  A tandem SAR shall be 
exercisable only during the period when the Option to which it is related is also exercisable.  

9  

   
   
   
   
   
   
   
   
   
   
 
(d)                                  Grants to Non-Exempt Employees .   Notwithstanding the foregoing, SARs granted to persons who are non-exempt 
employees under the FLSA may not be exercisable for at least six months after the date of grant (except that such SARs may become exercisable, 
as determined by the Board, upon the Grantee’s death, Disability or retirement, or upon a Change of Control or other circumstances permitted by 
applicable regulations).  

(e)                                   Value of SARs .   When a Grantee exercises SARs, the Grantee shall receive in settlement of such SARs an amount equal to 

the value of the stock appreciation for the number of SARs exercised.  The stock appreciation for an SAR is the amount by which the Fair Market 
Value of the underlying Company Stock on the date of exercise of the SAR exceeds the base amount of the SAR as described in Section 8(a).  

(f)                                    Form of Payment .   The appreciation in an SAR shall be paid in shares of Company Stock, cash or any combination of the 

foregoing, as the Board shall determine.  For purposes of calculating the number of shares of Company Stock to be received, shares of Company 
Stock shall be valued at their Fair Market Value on the date of exercise of the SAR.  

9.                                       Other Equity Awards .  The Board may grant Other Equity Awards, which are awards (other than those described in Sections 
5, 6, 7 and 8 of this Plan) that are based on, measured by or payable in Company Stock, including, without limitation, stock appreciation rights, to 
any Employee, Non-Employee Director or Key Advisor, on such terms and conditions as the Board shall determine.  Other Equity Awards may be 
awarded subject to the achievement of performance goals or other conditions and may be payable in cash, Company Stock or any combination of 
the foregoing, as the Board shall determine.  

10.                                Withholding of Taxes .  

(a)                                  Required Withholding .  All Grants under this Plan shall be subject to applicable federal (including FICA), state and local tax 

withholding requirements.  The Employer may require that the Grantee or other person receiving or exercising Grants pay to the Employer the 
amount of any federal, state or local taxes that the Employer is required to withhold with respect to such Grants, or the Employer may deduct from 
other wages paid by the Employer the amount of any withholding taxes due with respect to such Grants.  

(b)                                  Election to Withhold Shares .   If the Board so permits, a Grantee may elect to satisfy the Employer’s tax withholding 
obligation with respect to Grants paid in Company Stock by having shares withheld up to an amount that does not exceed the Grantee’s minimum 
applicable withholding tax rate for federal (including FICA), state and local tax liabilities.  The election must be in a form and manner prescribed 
by the Board and may be subject to the prior approval of the Board.  

11.                                Transferability of Grants .  

(a)                                  Nontransferability of Grants .   Except as provided below, only the Grantee may exercise rights under a Grant during the 
Grantee’s lifetime.  A Grantee may not transfer those rights except (i) by will or by the laws of descent and distribution or (ii) with respect to 
Grants other than Incentive Stock Options, if permitted in any specific case by the Board, pursuant to a domestic relations order or otherwise as 
permitted by the Board.  When a Grantee dies, the  

10  

   
   
   
   
   
   
   
   
   
   
 
personal representative or other person entitled to succeed to the rights of the Grantee may exercise such rights.  Any such successor must furnish 
proof satisfactory to the Company of his or her right to receive the Grant under the Grantee’s will or under the applicable laws of descent and 
distribution.  

(b)                                  Transfer of Nonqualified Stock Options .   Notwithstanding the foregoing, the Board may provide, in a Grant Instrument, 

that a Grantee may transfer Nonqualified Stock Options to family members, or one or more trusts or other entities for the benefit of or owned by 
family members, consistent with applicable securities laws, according to such terms as the Board may determine; provided that the Grantee

defined in Rule 13d-3 under the Exchange Act), directly or indirectly, of securities of the Company representing more than 50% of the voting 
power of the then outstanding securities of the Company; provided that a Change of Control shall not be deemed to occur as a result of (A) a 
transaction in which the Company becomes a subsidiary of another corporation and in which the stockholders of the Company, immediately prior 
to the transaction, will beneficially own, immediately after the transaction, shares entitling such stockholders to more than 50% of all votes to

by an investor of the Company in a capital-raising transaction; or

of the Company, immediately prior to the merger or consolidation, will not beneficially own, immediately after the merger or consolidation,

election of directors, (B) a sale or other disposition of all or substantially all of the assets of the Company, or (C) a liquidation or dissolution of the

and shall be payable.  The Board may condition any such acceleration on such terms as the Board determines.

(b)                                  Other Alternatives .   In the event of a Change of Control, the Board may take any of the following actions with respect to any 

or all outstanding Grants: the Board may (i) determine that all outstanding Options and SARs that are not exercised shall be assumed by, or 
replaced with comparable options by the surviving corporation (or a parent or subsidiary of the surviving corporation), and other outstanding 
Grants that remain in effect after the Change of Control shall be converted to similar grants of the surviving corporation (or a parent or subsidiary 
of the surviving corporation), (ii) require that Grantees surrender their outstanding Options and SARs in exchange for one or more payments, in 
cash or Company Stock as determined by the Board, in an amount, if any, equal to the amount by which the then Fair Market Value of the shares 
of Company Stock subject to the Grantee’s unexercised Options and SARs exceeds the Exercise Price or base amount of the Options and SARs, 
on such terms as the Board determines, or (iii) after giving Grantees an opportunity to exercise their outstanding Options and SARs, terminate any 
or all unexercised Options and SARs at such time as the Board deems appropriate.  Such assumption, surrender or termination shall take place as 
of the date of the Change of Control or such other date as the Board may specify.  

14.                                Limitations on Issuance or Transfer of Shares .

pursuant to this Plan.  If such stockholders agreement or voting agreement contains any lock-up or market standoff provisions that differ from the 
provisions of Section 14(c) of this Plan, for as long as the provisions of such agreement are in effect, the provisions of Section 14(c) shall not 
apply to such Company Stock, unless the Board determines otherwise.  

(b)                                  Limitations on Issuance or Transfer of Shares .   No Company Stock shall be issued or transferred in connection with any 

Grant hereunder unless and until all legal requirements applicable to the issuance or transfer of such Company Stock have been complied with to 
the satisfaction of the Board.  The Board shall have the right to condition any Grant made to any Grantee hereunder on such Grantee’s undertaking 
in writing to comply with such restrictions on his or her subsequent disposition of such shares of Company Stock as the Board shall deem 
necessary or advisable, and certificates representing such shares may be legended to reflect any such restrictions.  Certificates representing shares 
of Company Stock issued or transferred under this Plan will be subject to such stop-transfer orders and other restrictions as may be required by 
applicable laws, regulations and interpretations, including any requirement that a legend be placed thereon.  

(c)                                   Lock-Up Period .  If so requested by the Company or any representative of the underwriters (the “Managing Underwriter”) in 

connection with any underwritten offering of securities of the Company under the Securities Act, and subject to Section 14(a) of this Plan, a

12  

   
   
   
   
   
   
 
agreement to such effect in form and substance requested by the Company or the Managing Underwriter.  The Company may impose stop-transfer 
instructions with respect to securities subject to the foregoing restrictions until the end of such Market Standoff Period.

amendment in the manner required by section 162(m); and (ii) if shares of the Company’s capital stock are listed on the Exchange, no amendment

approve such amendment.  In addition, if at any time the approval of the Company’s stockholders is required as to any other modification or 
amendment under section 422 of the Code or any successor provision with respect to Incentive Stock Options, the Board may not effect such 
modification or amendment without such approval.  Unless otherwise specified in the amendment, any amendment to this Plan adopted in 
accordance with this Section 15(a) shall apply to, and be binding on the holders of, all Grants outstanding under this Plan at the time the 
amendment is adopted, provided the Board determines that such amendment, taking into account any related action, does not materially and 
adversely affect the rights of Grantees under this Plan.  No Grant shall be made that is conditioned upon stockholder approval of any amendment 
to this Plan unless the Grant provides that (i) it will terminate or be forfeited if stockholder approval of such amendment is not obtained within no 
more than 12 months from the date of grant and (ii) it may not be exercised or settled (or otherwise result in the issuance of Company Stock) prior 
to such stockholder approval.  

(b)                                  Termination of This Plan .  This Plan shall terminate on the day immediately preceding the tenth anniversary of its effective

including but not limited to substituting therefor another Grant of the same or a different type, changing the date of exercise or realization, and/or 
converting an Incentive Stock Option into a Nonqualified Stock Option.  A termination or amendment of this Plan that occurs after a Grant is 
made shall not materially impair the rights of a Grantee unless the Grantee consents or unless the Board acts under Section 21(b).  The termination 
of this Plan shall not impair the power and authority of the Board with respect to an outstanding Grant.  The Board may at any time provide that 
any Grant shall become immediately exercisable in whole or in part, free of some or all restrictions or conditions, or otherwise realizable in whole 
or in part, as the case may be.  

(d)                                  Governing Document .  This Plan shall be the controlling document.  No other statements, representations, explanatory

otherwise, of the business or assets of any corporation, firm or association, including Grants to employees thereof who become Employees, or for 
other proper corporate purposes, or (ii) limit the right of the Company to grant stock options or make other awards outside of this Plan.  Without

Employee Director or Key Advisor by reason of a corporate merger, consolidation, acquisition of stock or property, reorganization or liquidation 
involving the Company, the Parent or any of their subsidiaries in substitution for a stock option or stock award grant made by such corporation.

applicable law, the Board may determine that such Plan provision shall cease to apply.  The Board may revoke any Grant if it is contrary to law or 
modify a Grant or this Plan to bring the Grant or this Plan into compliance with any applicable law or regulation.  

(c)                                   Employees Subject to Taxation Outside the United States .   With respect to Grantees who are subject to taxation in 
countries other than the United States, the Board may make Grants on such terms and conditions as the Board deems appropriate to comply with 
the laws of the applicable countries, and the Board may create such procedures, addenda and subplans and make such modifications as may be 
necessary or advisable to comply with such laws.  

(d)                                  Governing Law .  The validity, construction, interpretation and effect of this Plan and Grant Instruments issued under this Plan

such reduction is part of a Company-wide reduction in compensation and/or benefits for all of its senior executives; provided, however, that Good 
Reason shall not include a termination of the Employee’s employment pursuant to Section 4(b) or 4(c) hereof or, following a Change in Control, a 
reduction in title, position, responsibilities or duties solely by virtue of the Company being acquired and made part of a larger entity or operated as 
a subsidiary.  If the Employee shall terminate the Employee’s employment hereunder for Good Reason, the Employee shall be entitled to receive 
the same payments and benefits on the same terms and conditions as would be applicable upon a termination of the Employee’s employment by 
the Company without Cause, as provided in Section 4(d) and subject to the satisfaction of the  

4  

   
   
   
 
other provisions of this Section 4(e).  The Employee may not resign with Good Reason pursuant to this Section 4(e), and shall not be considered 
to have done so for any purpose of this Agreement, unless (A) the Employee, within 60 days after the initial existence of the act or failure to act by 
the Company that constitutes “Good Reason” within the meaning of this Agreement, provides the Company with written notice that describes, in 
particular detail, the act or failure to act that the Employee believes to constitute “Good Reason” and identifies the particular clause of this 
Section 4(e) that the Employee contends is applicable to such act or failure to act; (B) the Company, within 30 days after its receipt of such notice, 
fails or refuses to rescind such act or remedy such failure to act so as to eliminate “Good Reason” for the termination by the Employee of the 
Employee’s employment relationship with the Company, and (C) the Employee actually resigns from the employ of the Company on or before 
that date that is six calendar months after the initial existence of the act or failure to act by the Company that constitutes “Good Reason.”  If the 
requirements of the preceding sentence are not fully satisfied on a timely basis, then the resignation by the Employee from the Employee’s 
employment with the Company shall not be deemed to have been for “Good Reason,” the Employee shall not be entitled to any of the benefits to 
which the Employee would have been entitled if the Employee had resigned the Employee’s employment with the Company for “Good Reason,” 
and the Company shall not be required to pay any amount or provide any benefit that would otherwise have been due to the Employee under this 
Section 4(e) had the Employee resigned with “Good Reason.”  

(f)                                    Other Termination by the Employee.   The Employee may terminate the Employee’s employment for any reason 

other than one specified in Section 4(e) upon at least 30 days’ prior written notice to the Company, which notice shall specify the effective date of 
the termination.  In the event the Employee shall terminate the Employee’s employment pursuant to this Section 4(f), the Company shall not have 
any further obligation or liability under this Agreement, except that the Company shall pay to the Employee:  (i) any portion of the Employee’s 
Base Salary for the period up to the date of termination that has been earned but remains unpaid; and (ii) any benefits that have accrued to the 
Employee under the terms of the employee benefit plans of the Company, which benefits shall be paid in accordance with the terms of those plans. 

(g)                                  Execution of Release.  The Employee shall not be entitled to any payments or benefits under Sections 4(d) or 4

(e) unless the Employee executes and does not revoke a Release and Agreement (the “Release”), as drafted at the time of the Employee’s 
termination of employment, including, but not limited to:  

(i)                                      an unconditional release of all rights to any claims, charges, complaints, grievances, known or unknown to 
the Employee, against the Company, its affiliates or assigns, through the date of the Employee’s termination from employment other than post-
termination payments and benefits pursuant to this Agreement;  

grievances against the Company, its affiliates, or assigns;  

(ii)                                   a representation and warranty that the Employee has not filed or assigned any claims, charges, complaints, or 

5  

   
   
   
   
   
   
 
to return any such confidential information and property to the Company upon execution of the Release;  

(iii)                                an agreement not to use, disclose or make copies of any confidential information of the Company, as well as 

of employment;  

(iv)                               a mutual agreement to maintain the confidentiality of the Release or disclose the reasons for any termination 

(v)                                  an agreement not to disparage the Company or its officers, directors, stockholders, products or business; and  

any portion of this Agreement or the Release.  

(vi)                               an agreement to indemnify the Company, or its affiliates or assigns, in the event that the Employee breaches 

Notwithstanding any provision of this Agreement to the contrary, in no event shall the timing of the Employee’s execution of the Release, directly 
or indirectly, result in the Employee designating the calendar year of payment, and if a payment that is subject to execution of the Release could 
be made in more than one taxable year, payment shall be made in the later taxable year.  

(h)                                  Definition of Change in Control.   As used in this Agreement, the term “Change in Control” means:  

(i)                                      any merger or consolidation in which voting securities of the Company possessing more than 50% of the total 

combined voting power of the Company’s outstanding securities are transferred to a person or persons different from the person holding those 
securities immediately prior to such transaction and the composition of the Board following such transaction is such that the directors of the 
Company prior to the transaction constitute less than 50% of the Board membership following the transaction;  

(ii)                                   any acquisition, directly or indirectly, by a person or related group of persons (other than the Company or a 

person that directly or indirectly controls, is controlled by, or is under common control with, the Company) of beneficial ownership of voting 
securities of the Company possessing more than 50% of the total combined voting power of the Company’s outstanding securities; provided, 
however, that, no Change in Control shall be deemed to occur by reason of the acquisition of shares of the Company’s capital stock by an investor 
or group of investors in the Company in a capital-raising transaction; or  

the Company; or  

(iii)                                any sale, transfer, exclusive worldwide license or other disposition of all or substantially all of the assets of 

(iv)                               within any 24-month period beginning on or after the date hereof, the persons who were directors of the 

Company immediately before the beginning of such period (the “Incumbent Directors”) shall cease (for any reason other than death) to constitute 
at least a majority of the Board of Directors of the Company or the board of directors of any successor to the Company, provided that any director 
who was not a director as of the date hereof shall be deemed to be an Incumbent Director if such director was elected to the Board by, or on the 
recommendation of or with the approval of, at least two-thirds of the directors who then qualified as Incumbent Directors either actually or by 
prior operation of this Section 4(h)(iv), unless such  

6  

   
   
   
   
   
   
   
   
   
   
   
 
election, recommendation or approval was the result of an actual or threatened contested election of directors pursuant to Regulation 14A under 
the Securities Exchange Act of 1934 or any successor provision.  

(i)                                     Base Salary Continuation.  The Base Salary continuation set forth in Sections 4(d) and (e) above shall be intended 
either (i) to satisfy the safe harbor set forth in the regulations issued under section 409A of the Internal Revenue Code of 1986, as amended (the 
“Code”) (Treas. Regs. 1.409A-1(n)(2)(ii)) or (ii) be treated as a Short-term Deferral as that term is defined under Code section 409A (Treas. Regs. 
1.409A-1(b)(4)).  To the extent such continuation payments exceed the applicable safe harbor amount or do not constitute a Short-term Deferral, 
the excess amount shall be treated as deferred compensation under Code section 409A and as such shall be payable pursuant to the following 
schedule: such excess amount shall be paid via standard payroll in periodic installments in accordance with the Company’s usual practice for its 
senior executives.  Solely for purposes of Code section 409A, each installment payment is considered a separate payment.  Notwithstanding any 
provision in this Agreement to the contrary, in the event that the Employee is a “specified employee” as defined in Section 409A, any continuation 
payment, continuation benefits or other amounts payable under this Agreement that would be subject to the special rule regarding payments to 
“specified employees” under Section 409A(a)(2)(B) of the Code shall not be paid before the expiration of a period of six months following the 
date of the Employee’s termination of employment or before the date of the Employee’s death, if earlier.  

(j)                                     Parachute Provisions.   Notwithstanding any provisions of this Agreement to the contrary:  

(i)                                      If any of the payments or benefits received or to be received by the Employee in connection with the 

Employee’s termination of employment in respect of a Change in Control, whether pursuant to the terms of this Agreement or any other plan, 
arrangement or agreement with the Company (all such payments and benefits, being hereinafter referred to as the “Total Payments”), would be 
subject to the excise tax (the “Excise Tax”) imposed under Section 4999 of the Code, the Employee shall receive the Total Payments and be 
responsible for the Excise Tax; provided, however that the Employee shall not receive the Total Payments and the Total Payments shall be 
reduced to the Safe Harbor Amount (defined below) if (A) the net amount of such Total Payments, as so reduced to the Safe Harbor Amount (and 
after subtracting the net amount of federal, state and local income taxes on such reduced Total Payments) is greater than or equal to (B) the net 
amount of such Total Payment without such reduction (but after subtracting the net amount of federal, state and local income taxes on such Total 
Payments and the amount of Excise Tax to which the Employee would be subject in respect of such unreduced Total Payments).  The “Safe 
Harbor Amount” is the amount to which the Total Payments would hypothetically have to be reduced so that no portion of the Total Payments 
would be subject to the Excise Tax.  

(ii)                                   For purposes of determining whether any of the Total Payments will be subject to the Excise Tax and the 

amount of such Excise Tax, (A) all of the Total Payments shall be treated as “parachute payments” (within the meaning of Section 280G(b)(2) of 
the Code) unless, in the opinion of tax counsel (“Tax Counsel”) selected by the accounting firm that was, immediately prior to the Change in 
Control, the Company’s independent auditor (the  

7  

   
   
   
   
   
   
 
“Auditor”), such payments or benefits (in whole or in part) do not constitute parachute payments, including by reason of Section 280G(b)(4)(A) of 
the Code, (B) all “excess parachute payments” within the meaning of Section 280G(b)(1) of the Code shall be treated as subject to the Excise Tax 
unless, in the opinion of Tax Counsel, such excess parachute payments (in whole or in part) represent reasonable compensation for services 
actually rendered (within the meaning of Section 280G(b)(4)(B) of the Code) in excess of the base amount (within the meaning of Section 280G
(b)(3) of the Code) allocable to such reasonable compensation, or are otherwise not subject to the Excise Tax, and (C) the value of any noncash 
benefits or any deferred payment or benefit shall be determined by the Auditor in accordance with the principles of Sections 280G(d)(3) and (4) of 
the Code.  If the Auditor is prohibited by applicable law or regulation from performing the duties assigned to it hereunder, then a different auditor, 
acceptable to both the Company and Employee, shall be selected.  The fees and expenses of Tax Counsel and the Auditor shall be paid by the 
Company.  

(iii)                                In the event it is determined that the Safe Harbor Amount is payable to Employee, then the severance 
payments provided under this Agreement that are cash shall first be reduced on a pro rata basis, and the non-cash severance payments shall 
thereafter be reduced on a pro rata basis, to the extent necessary so that no portion of the Total Payments is subject to the Excise Tax.  

5.                                       Restrictive Covenant Agreement.   The Non-Disclosure, Invention Assignment, Non-Solicitation and Non-Compete 

Agreement executed by the Employee on December 29, 2014 (the “Restrictive Covenant Agreement”) shall remain in full force and effect in 
accordance with its terms and shall survive the termination of this Agreement in accordance with the terms of the Restrictive Covenant 
Agreement.  

6.                                       Supersedes Other Agreements.   This Agreement supersedes and is in lieu of any and all other employment arrangements 

between the Employee and the Company, but shall not supersede the Restrictive Covenant Agreement or any existing confidentiality, 
nondisclosure, invention assignment or non-compete agreement between the Employee and the Company.  

7.                                       Amendments.   Any amendment to this Agreement shall be made in writing and signed by the parties hereto.  

8.                                       Enforceability.   If any provision of this Agreement shall be invalid or unenforceable, in whole or in part, then such provision 

shall be deemed to be modified or restricted to the extent and in the manner necessary to render the same valid and enforceable, or shall be 
deemed excised from this Agreement, as the case may require, and this Agreement shall be construed and enforced to the maximum extent 
permitted by law as if such provision had been originally incorporated herein as so modified or restricted or as if such provision had not been 
originally incorporated herein, as the case may be.  

9.                                       Construction.   This Agreement shall be construed and interpreted in accordance with the internal laws of the Commonwealth 

of Pennsylvania.

(a)                                  By the Company.   The rights and obligations of the Company under this Agreement shall inure to the benefit of, and 
shall be binding upon, the successors and assigns of the Company.  This Agreement may be assigned by the Company without the consent of the 
Employee.  

(b)                                  By the Employee.   This Agreement and the obligations created hereunder may not be assigned by the Employee, but 

all rights of the Employee hereunder shall inure to the benefit of and be enforceable by the Employee’s heirs, devisees, legatees, executors, 
administrators and personal representatives.  

11.                                Notices.   All notices required or permitted to be given hereunder shall be in writing and shall be deemed to have been given 

when mailed by certified mail, return receipt requested, or delivered by a national overnight delivery service addressed to the intended recipient as 
follows:  

If to the Company:  

Marinus Pharmaceuticals, Inc.  
3 Radnor Corporate Center  
100 Matsonford Road, Suite 304  
Radnor, PA  19087  
Attention:  Chairman of the Board  

If to the Employee:

205 Church Street  
Wayne, PA  19087  

Any party may from time to time change its address for the purpose of notices to that party by a similar notice specifying a new address, but no 
such change shall be deemed to have been given until it is actually received by the party sought to be charged with its contents.  

12.                                Waivers.   No claim or right arising out of a breach or default under this Agreement shall be discharged in whole or in part by a 

waiver of that claim or right unless the waiver is supported by consideration and is in writing and executed by the aggrieved party hereto or such 
party’s duly authorized agent.  A waiver by any party hereto of a breach or default by the other party hereto of any provision of this Agreement 
shall not be deemed a waiver of future compliance therewith, and such provisions shall remain in full force and effect.  

13.                                Section 409A.   It is intended that this Agreement be drafted and administered in compliance with section 409A of the Code, 

including, but not limited to, any future amendments to Code section 409A, and any other Internal Revenue Service or other governmental rulings 
or interpretations (together, “Section 409A”) issued pursuant to Section 409A so as not to subject the Employee to payment of interest or any 
additional tax under Code section 409A.  The parties  

9  

   
   
   
   
   
   
   
   
   
   
   
   
 
intend for any payments under this Agreement to either satisfy the requirements of Section 409A or to be exempt from the application of 
Section 409A, and this Agreement shall be construed and interpreted accordingly.  In furtherance thereof, if payment or provision of any amount 
or benefit hereunder that is subject to Section 409A at the time specified herein would subject such amount or benefit to any additional tax under 
Section 409A, the payment or provision of such amount or benefit shall be postponed to the earliest commencement date on which the payment or 
provision of such amount or benefit could be made without incurring such additional tax.  In addition, to the extent that any Internal Revenue 
Service guidance issued under Section 409A would result in the Employee being subject to the payment of interest or any additional tax under 
Section 409A, the parties agree, to the extent reasonably possible, to amend this Agreement in order to avoid the imposition of any such interest or 
additional tax under Section 409A, which amendment shall have the minimum economic effect necessary and be reasonably determined in good 
faith by the Company and the Employee.  

14.                                Survival of Covenants.   Each provision of this Agreement that, by its terms, is intended to continue beyond the termination of 

the Employee’s employment shall continue in effect thereafter.

be exercised pursuant to the provisions of Section 3.3, be exercised by the Employee’s personal representative or by any person empowered to do 
so under the Employee’s will or under the then applicable laws of descent and distribution.  

Section 4.2 - Partial Exercise  

Any exercisable portion of the Option or the entire Option, if then wholly exercisable, may be exercised at any time prior to the time 

when the Option or portion thereof may no longer be exercised pursuant to the provisions of Article 3; provided, however, that each partial 
exercise shall be for whole shares only.  

Section 4.3 - Manner of Exercise  

The Option, or any exercisable portion thereof, may be exercised solely by delivery to the Secretary of the Company of all of the 

following prior to the time when the Option or such portion may no longer be exercised pursuant to the provisions of Article 3:  

(a)                                  Notice in writing signed by the Employee or the other person then entitled to exercise the Option, stating that the Option or a 

portion thereof is thereby exercised, such notice complying with all applicable rules established by the Committee;  

(b)                                  (i)                                      Full payment (in cash or by check) for the shares with respect to which the Option or portion is exercised; or

the Act and then applicable rules and regulations thereunder, and that the Employee or other person then entitled to exercise the Option or portion 
will indemnify the Company against and hold it free and harmless from any loss, damage, expense or liability resulting to the Company if any sale 
or distribution of the shares by such person is contrary to the representation and agreement referred to above.  The Committee may, in its absolute 
discretion, take whatever additional actions it deems appropriate to ensure the observance and performance of such representation and agreement 
and to effect compliance with the Act and any other federal or state securities laws or regulations.  Without limiting the generality of the

regulations of the Securities and Exchange Commission or of any other governmental regulatory body, which the Committee shall, in its absolute 
discretion, deem necessary or advisable;  

(c)                                   The obtaining of any approval or other clearance from any state or federal governmental agency which the Committee shall, in 

its absolute discretion, determine to be necessary or advisable; and

respect to the Plan or the Option.  

Section 5.3 - Withholding

Section 4.2 - Partial Exercise  

Any exercisable portion of the Option or the entire Option, if then wholly exercisable, may be exercised in whole or in part at any time 

prior to the time when the Option or portion thereof becomes unexercisable under Section 3.3; provided, however, that each partial exercise shall 
be for whole shares only.  

Section 4.3 - Manner of Exercise  

The Option, or any exercisable portion thereof, may be exercised solely by delivery to the Secretary of the Company of all of the 

following prior to the time when the Option or such portion becomes unexercisable under Section 3.3:  

(a)                                  Notice in writing signed by the Director or the other person then entitled to exercise the Option or any portion, stating that the 

Option or portion is thereby exercised, such notice complying with all applicable rules established by the Committee;  

(b)                                  Full payment (in cash or by check) for the shares with respect to which the Option or portion is exercised;  

(c)                                   A bona fide written representation and agreement in a form satisfactory to the Board, signed by the Director or other person 
then entitled to exercise the Option or portion, stating that the shares of stock are being acquired for the Director’s own account, for investment 
and without any present intention of distributing or reselling said shares or any of them except as may be permitted under the Act, and then 
applicable rules and regulations thereunder, and that the Director or other person then entitled to exercise the Option or portion will indemnify the 
Company against and hold it free and harmless from any loss, damage, expense or liability resulting to the Company if any sale or distribution of 
the shares by such person is contrary to the representation and agreement referred to above.  The Committee may, in its absolute discretion, take 
whatever additional action it deems appropriate to ensure the observance and performance of such representation and agreement and to effect 
compliance with the Act and any other federal or state securities laws or regulations.  Without limiting the generality of the foregoing, the 
Committee may require an opinion of counsel acceptable to it to the effect that any subsequent transfer of shares acquired on an Option exercise 
does not violate the Act, and may issue stop-transfer orders covering such shares.  Share certificates evidencing stock issued on exercise of the 
Option shall bear an appropriate legend referring to the provisions of this Section 4.3(c) and the agreements contained in this Agreement.  The 
written representation and agreement referred to in the first sentence of this Section 4.3(c) shall, however, not be required if the shares to be issued 
pursuant to such exercise have been registered under the Act, and such registration is then effective in respect of such shares;  

(d) In the event the Option or portion shall be exercised pursuant to Section 4.1 by any person or persons other than the Director, 

appropriate proof of the right of such person or persons to exercise the Option.

unissued shares or issued shares that have then been reacquired by the Company.  Such shares shall be fully paid and nonassessable.  The 
Company shall not be required to issue or deliver any certificate or certificates for shares of Common Stock purchased upon the exercise of the 
Option or portion thereof prior to fulfillment of all of the following conditions:  

(a)                                  The admission of such shares to listing on all stock exchanges or stock markets on which such class of stock is then listed;  

(b)                                  The completion of any registration or other qualification of such shares under any state or federal law or under rulings or 

regulations of the Securities and Exchange Commission or of any other governmental regulatory body, which the Committee shall, in its absolute 
discretion, deem necessary or advisable;  

(c)                                   The obtaining of any approval or other clearance from any state or federal government agency which the Committee shall, in its 

absolute discretion, determine to be necessary or advisable; and  

(d)                                  The lapse of such reasonable period of time following the exercise of the Option as the Committee may from time to time 

establish for reasons of administrative convenience.  

Section 4.5 - Rights as Stockholder  

The holder of the Option shall not be, nor have any of the rights or privileges of, a stockholder of the Company in respect of any shares 

purchasable upon the exercise of any part of the Option unless and until such part of the Option is exercised in accordance with its terms.

any other legal or equitable proceedings (including bankruptcy), and any attempted disposition thereof shall be null and void and of no effect;

registrant’s most recent fiscal quarter (the registrant’s fourth fiscal quarter in the case of an annual report) that has materially affected, or is 
reasonably likely to materially affect, the registrant’s internal control over financial reporting; and  

5.                                       The registrant’s other certifying officer(s) and I have disclosed, based on our most recent evaluation of internal control over 

financial reporting, to the registrant’s auditors and the audit committee of the registrant’s board of directors (or persons performing the equivalent 
functions):  

(a)                                  All significant deficiencies and material weaknesses in the design or operation of internal control over financial reporting which 

are reasonably likely to adversely affect the registrant’s ability to record, process, summarize and report financial information; and  

(b)                                  Any fraud, whether or not material, that involves management or other employees who have a significant role in the registrant’s 

internal control over financial reporting.
