PART I



|Item 1. | Business.

Overview

We are an emerging specialty pharmaceutical company focused on the development of pharmaceutical products based on our proprietary drug
delivery technology platforms. Our product pipeline currently consists of six investigational drug candidates in clinical development, with one program the subject of a New Drug Application (NDA) with the U.S. Food and Drug Administration (FDA), one
program in Phase III, two programs in Phase II and two programs in Phase I. These more advanced programs are all in the field of pain management and we believe that each of these targets large market opportunities with product features that are
differentiated from existing therapeutics. We have other earlier stage research programs underway in fields outside of pain management, including several efforts underway which seek to improve the administration of biotechnology agents such as
proteins and peptides.

A central aspect of our business strategy involves advancing multiple product candidates at one time,
which is enabled by leveraging our resources with those of corporate collaborators. Thus, certain of our programs are currently licensed to corporate collaborators on terms which typically call for our collaborator to fund all or a substantial
portion of future development costs and then pay us milestone payments based on specific development or commercial achievements plus a royalty on product sales. At the same time, we have retained the rights to other programs, which are the basis of
future collaborations and over time may provide a pathway for us to develop our own commercial, sales and marketing organization.

Remoxy (ORADUR-Oxycodone)

Market Opportunity.    Chronic pain is usually the result of an ongoing condition or
significant problem associated with chronic diseases, including cancer, various neurological and skeletal disorders and other ailments such as severe arthritis or a debilitating back injury. As the condition gets worse, the pain often gets worse.
Also, long-lasting pain can affect the nervous system to the point where pain persists even if the condition that originally caused the pain is stabilized or improved. This is one reason patients often need stronger pain medication even if their
underlying condition has been treated. Chronic pain affects as many as 50 million Americans annually. OxyContin®, a brand name extended-release oral oxycodone-based painkiller, accounted for approximately $2.8 billion in worldwide sales in 2009.

Development Strategy.    Remoxy is an oral, long-acting oxycodone gelatin capsule under development with Pain Therapeutics, Inc. (Pain Therapeutics) to which we have licensed
exclusive, worldwide, development and commercialization rights under a development and license agreement entered into in December 2002. Subsequently, Pain Therapeutics has sublicensed the commercialization rights of Remoxy to King Pharmaceuticals,
Inc. (King) and, as of March 2009, we are working directly with King on further development of Remoxy. Remoxy is formulated with our ORADUR technology and incorporates several abuse-deterrent properties with the convenience of twice-a-day dosing.
Oxycodone is also the active drug ingredient in OxyContin®, a brand name extended-release oral painkiller, which
achieved annual worldwide sales of approximately $2.8 billion in 2009. Under the agreement with Pain Therapeutics, subject to and upon the achievement of predetermined development and regulatory milestones, we are entitled to receive milestone
payments of up to $9.3 million in the aggregate. As of December 31, 2009, we had received $1.7 million in cumulative milestone payments. We also receive reimbursement for our research and development efforts on Remoxy and a manufacturing profit
on our supply of key product excipients for use in Remoxy. In addition, if commercialized, we will receive royalties for Remoxy and other licensed products which do not contain an opiod antagonist of between 6.0% to 11.5% of net sales depending on
sales volumes.

Clinical Program.    In December 2007, Pain Therapeutics and King announced that
the pivotal Phase III trial for Remoxy successfully met its primary endpoint (p<0.01) that was prospectively defined by the FDA during the Special Protocol Assessment process. In addition, the study achieved statistically significant
results in secondary endpoints such as Quality of Analgesia (p<0.01) and Global Assessment (p<0.01). Pain Therapeutics submitted an NDA for Remoxy to the FDA in June 2008, and in August 2008 the FDA accepted the NDA and granted priority
review. In December 2008, Pain Therapeutics received a Complete Response Letter for its NDA for Remoxy in which the FDA determined that the NDA was not approved. According to Pain Therapeutics, the FDA indicated that additional non-clinical data
would be required to support the approval of Remoxy, but the FDA has not requested or recommended additional clinical efficacy studies prior to approval. King assumed responsibility for further development of Remoxy from Pain Therapeutics in March
2009. On July 2, 2009, King met with the FDA to discuss the Complete Response Letter. According to King and Pain Therapeutics, the outcome of that meeting provided King with a clearer path forward to resubmit the Remoxy NDA and to address all
FDA comments in the Complete Response Letter. King recently announced that it has undertaken a likeability study and a pharmacokinetic trial in volunteers and plans to resubmit the NDA in the fourth quarter of 2010.

Additional ORADUR-Opioid Products in Development

During 2006, 2007 and 2008, we also worked with Pain Therapeutics and King on the development of additional ORADUR abuse-resistant opioid drug candidates which would address the chronic pain market.
Phase I clinical trials have been completed for two of these ORADUR-based products. The active ingredients in these two drug candidates are opioids whose identities have not been publicly disclosed.

POSIDUR

Market Opportunity.    According to data published by the Center for Disease Control and Prevention, there are approximately 72 million ambulatory and inpatient procedures performed annually in the U.S.

##### Table of Contents

Epidemiological studies indicate that up to 100% of surgical patients experience postoperative pain, with 50-75% reporting inadequate pain relief. The current standard of care for post-surgical
pain includes oral opiate and non-opiate analgesics, transdermal opiate patches and muscle relaxants. While oral analgesics can effectively control post-surgical pain, they commonly cause side effects including drowsiness, constipation and cognitive
impairment. Effective pain management can be compromised if patients fail to adhere to recommended dosing regimens because they are sleeping or disoriented. Post-surgical pain also can be treated effectively with local anesthetics; however, the
usefulness of current conventional medications is limited by their short duration of action.

Development
Strategy.    We are developing POSIDUR, a sustained-release formulation of bupivacaine, using our SABER delivery system for the treatment of post-surgical pain. Bupivacaine is a local anesthetic agent currently used in the
hospital for anesthesia and analgesia and for which the patent covering the chemical entity has expired. The physician would administer POSIDUR at the time of surgery to the surgical site. This formulation is designed to provide sustained regional
analgesia from a single dose. We believe that by delivering effective amounts of a potent analgesic to the location from which the pain originates, adequate pain control can be achieved with minimal exposure to the remainder of the body, thus
minimizing side effects. POSIDUR is intended to provide local analgesia for up to 3 days, which we believe coincides with the time period of greatest need for post-surgical pain control in most patients.

In November 2006, we entered into a collaboration agreement with Nycomed Danmark ApS (Nycomed), which was subsequently amended in February
2010. Under the terms of the amended agreement, as amended, we licensed to Nycomed the exclusive commercialization rights to POSIDUR for the European Union (E.U.) and certain other countries. Nycomed paid us an upfront license fee of $14.0 million
in 2006 and an $8.0 million milestone payment in 2007, with future potential additional milestone payments of up to $181.0 million upon achievement of defined development, regulatory and sales milestones. Prior to the February 2010 amendment, the
agreement provided for us and Nycomed to jointly direct and equally fund a development program for POSIDUR intended to secure regulatory approval in both the U.S. and the E.U. After the amendment, we now have final decision-making authority over
clinical trials intended for the U.S. registration of POSIDUR. Subject to our right to initiate dispute resolution procedures in specified circumstances, Nycomed will now have final decision-making authority over clinical trials for the E. U. and
other countries licensed to it. We have funding responsibility for all current and future clinical trials intended for U.S. registration of POSIDUR and, commencing April 1, 2010, Nycomed will have sole funding responsibility for all clinical
trials intended for E.U. registration of POSIDUR. The final decision making authority and financial responsibility for the remainder of the development activities, such as the non-clinical and CMC activities, will be jointly managed and funded by
DURECT and Nycomed. In addition, we will manufacture and supply the product to Nycomed for commercial sale in the territory licensed to Nycomed. Nycomed will pay us blended royalties on sales in the defined territory of 15-40% depending on annual
sales, as well as a manufacturing markup. We retain full commercial rights to POSIDUR in the U.S., Canada, Japan and certain other countries.

Clinical Program.    In 2007, we successfully completed a 122 patient Phase IIb clinical trial of POSIDUR for treatment of post-operative pain in patients undergoing inguinal
hernia repair. In the Phase IIb trial, POSIDUR at a dose of 5 mL demonstrated statistically significant reductions in pain and in total consumption of supplemental opioid analgesic medications versus placebo. These successful results triggered the
$8.0 million milestone payment by Nycomed to us under our agreement with Nycomed.

Phase IIb Inguinal Hernia Trial

Design

The
POSIDUR Phase IIb clinical trial was designed to evaluate the tolerability, activity, dose response and pharmacokinetics of POSIDUR in patients undergoing open inguinal hernia repair. The trial was conducted in Australia and New Zealand as a
multi-center, randomized, double blind, placebo-controlled study in 122 patients. Study patients were randomized into three treatment groups: patients that were treated with POSIDUR

2.5 mL (n=43), POSIDUR 5 mL (n=47) and placebo (n=32). The co-primary efficacy endpoints for the study were Mean Pain Intensity on Movement area under the curve (AUC), a measure of pain
over a period of 1-72 hours post-surgery, and the proportion of patients requiring supplemental opioid analgesic medication during the study. Secondary efficacy endpoints included Mean Pain Intensity on Movement AUC over the period 1-48 hours
post-surgery, mean total consumption of supplemental opioid analgesic medication, and time to first use of supplemental opioid analgesic medication. The threshold for statistical significance was considered to be at the p<0.05 level.

Results

Pain Control

In relation to the co-primary endpoint of pain reduction as measured by Mean Pain Intensity on
Movement AUC 1-72 hours post-surgery, the patient group treated with POSIDUR 5 mL reported thirty-one percent (31%) less pain versus placebo (p=0.0033). A secondary endpoint measure reported a thirty-five percent (35%) reduction of pain as
measured by Mean Pain Intensity on Movement AUC for the period 1-48 hours post-surgery between the POSIDUR 5 mL treatment group versus placebo (p=0.0007).

Consumption of Supplemental Opioid Analgesic Medication

Fifty-three
percent (53%) of the study patients in the POSIDUR 5 mL group took supplemental opioid analgesic medications versus seventy-two percent (72%) of the placebo patients (p=0.0909). Although this positive trend for this co-primary endpoint in
favor of the POSIDUR 5 mL group was not statistically significant, both secondary endpoints measuring opioid analgesic medication consumption were met at a statistically significant level. During the periods of 1-24 hours, 24-48 hours and 48-72
hours after surgery, placebo patients consumed approximately 3.5 (p=0.0009), 2.9 (p=0.0190) and 3.6 (p=0.0172) times more supplemental opioid analgesic medications (mean total daily consumption of opioid analgesic medication in morphine
equivalents), respectively, than the POSIDUR 5 mL treatment group. In addition, the median time to first use of supplemental opioid analgesic medication after surgery for the placebo patients was 2.7 hours versus >72 hours for the POSIDUR 5 mL
treatment group (p=0.0197).

Dose Finding

POSIDUR administered at the dose of 5 mL showed statistically significant activity relative to placebo whereas POSIDUR administered at 2.5 mL showed a positive trend relative to placebo on certain
parameters but the results were not statistically significant.

Safety

The patient groups treated with POSIDUR 5 mL and POSIDUR 2.5 mL showed comparable safety profiles as the patient groups treated with placebo,
and the drug administration appeared well tolerated. The side effects commonly observed with opioid medication use were less frequent in the POSIDUR 5 mL and 2.5 mL treatment groups compared to placebo.

Other Phase II Clinical Trials

In addition to the Phase IIb clinical trial described above, we have also conducted smaller exploratory Phase II studies in hernia, shoulder arthroscopy and appendectomy surgeries to evaluate different application techniques, clinical
design and conduct as well as other investigational factors. These trials have been conducted in multiple cohorts, generally consisting of approximately 6 to 21 patients in each treatment group. In all the exploratory studies, patient groups treated
with POSIDUR 5 mL and POSIDUR 2.5 mL showed comparable safety profiles as the patient groups treated with placebo, and the drug administration appeared well tolerated. Some treatment groups from these exploratory studies utilizing POSIDUR have shown
positive activity as

measured by reduction of pain or consumption of supplemental opioid analgesic medication versus placebo, while other treatment groups have not. We have evaluated these studies to understand the
different results observed, and have applied our learnings in the design of our Phase III program.

In December 2009, we
announced positive results from a 60 patient Phase IIb clinical trial of POSIDUR in patients undergoing arthroscopic shoulder surgery. Top line results showed a consistent reduction of pain scores (as measured by mean pain intensity on
movement AUC, time normalized under the curve, during the period 0 to 72 hours post-surgery) in parallel with a reduction of opioid use (as measured by the amount of opioids taken in the three days post-surgery) in favor of POSIDUR versus placebo.
These reductions were not statistically significant given the size of the study. In addition, there was a comparable safety profile between the two groups in this study and POSIDUR appeared well tolerated. Nycomed is currently conducting two Phase
IIb clinical trials in hysterectomy patients and in shoulder surgery patients. These trials are being conducted in a different manner than U.S. clinical trials and are designed to be suitable for European regulatory approval purposes.

January 2010, we announced that we had commenced BESST (Bupivacaine Effectiveness and Safety in SABER Trial), which is intended to be the pivotal Phase III clinical trial in the U.S. BESST is an international, multi-center, randomized, double-blind,
controlled trial evaluating the safety, efficacy, effectiveness, and pharmacokinetics of POSIDUR in approximately 300 patients undergoing a variety of general abdominal surgical procedures. Eligible patients will be randomly assigned to one of three
cohorts:

Cohort 1: An active comparator cohort in which patients are randomized to receive either POSIDUR 5.0 mL or
commercially available Bupivacaine HCl solution after laparotomy.

Cohort 2: An active comparator cohort in which patients are
randomized to receive either POSIDUR 5.0 mL or commercially available Bupivacaine HCl solution after laparoscopic cholecystectomy.

Cohort 3: A double blind, placebo controlled cohort in which patients are randomized to receive either POSIDUR 5.0 mL or SABER-Placebo after laparoscopically-assisted colectomy.

Efficacy evaluation in the BESST trial will encompass a number of parameters. The two co-primary efficacy endpoints for Cohort 3 will be
mean pain intensity on movement (normalized) Area Under the Curve (AUC) during the period 0-72 hours post-dose and mean total morphine equivalent opioid dose for supplemental analgesia during the period 0-72 hours post-dose. An adaptive feature of
BESST allows for increasing the patient sample size in Cohort 3 based on pooled and blinded data. The purpose of Cohorts 1 and 2 is to give us additional experience with the use of POSIDUR in a broader group of surgeries and patients.

ELADUR

Market Opportunity.    Pain can arise from a variety of diseases and conditions, and in many instances, pain originates from a localized point in the body and can benefit from treatments which are administered and
act locally as opposed to in a systemic fashion. One such example is post-herpetic neuralgia (PHN or post-shingles pain), a debilitating complication of herpes zoster, which is usually defined as the presence of pain at the site of eruption that
lasts more than a month after the onset of a zoster eruption. The prevalence of PHN (including PHN lasting more than one year) is estimated to be approximately 144,000 people in the U.S. In addition to PHN, there are a number of other widely
prevalent chronic and acute local pain conditions (e.g., neuropathic pain, back pain, sprains, strains, and contusions) that could benefit from a locally acting pain product.

Development Strategy.    We are developing a transdermal bupivacaine patch (ELADUR) based on our proprietary
TRANSDUR transdermal technology intended to provide continuous delivery of bupivacaine for up to three days from a single application, as compared to a wearing time limited to 12 hours with currently available lidocaine patches. We anticipate that
ELADUR will have several potential differentiating attributes

compared with currently marketed lidocaine patches, including extended duration of action and better wearability. During 2008, we received Orphan Drug Designation for bupivacaine for relief of
persistent pain associated with PHN, such that if ELADUR is the first bupivacaine product approved for PHN, ELADUR would be eligible to receive seven years of data exclusivity following its approval by the FDA. There can be no assurance that ELADUR
will be the first bupivacaine product approved for PHN, and therefore ELADUR may not be entitled to the seven year data exclusivity period for orphan drugs. Effective October 2008, we licensed the worldwide development and commercialization rights
for ELADUR to Alpharma Ireland Limited (Alpharma), which was acquired by King in December 2008. Together with King, we are exploring the development of ELADUR for a variety of clinical indications.

Clinical Program.    In 2007, we reported positive results from a completed 60 patient Phase IIa clinical
trial for ELADUR. In this study of patients suffering from PHN, ELADUR showed improved pain control versus placebo during the 3-day continuous treatment period. In addition, ELADUR appeared well tolerated overall, and patients treated with ELADUR
and placebo exhibited similar safety profiles. In 2008, we conducted manufacturing scale-up and processing studies to secure additional supplies for Phase II and Phase III clinical trials, and developed our clinical and regulatory strategy for
further development of this program. King has stated that it intends to initiate further studies with ELADUR in the first half of 2010.

TRANSDUR-Sufentanil Patch

Market
Opportunity.    Chronic pain affects as many as 50 million Americans annually. One major class of drugs utilized to treat chronic pain is comprised of oral opioids, such as OxyContin, a branded extended-release oral
oxycodone-based painkiller which accounted for approximately $2.8 billion in worldwide sales in 2009. Another major class of drugs utilized to treat chronic pain are transdermally delivered opioids such as Duragesic®, a leading transdermal fentanyl product which accounted for approximately $900 million in worldwide sales in 2009.
It is our belief that a best-in-class sufentanil patch could compete effectively in both the transdermal fentanyl patch market and in the oral opioid market.

Development Strategy.    Our transdermal sufentanil patch (TRANSDUR-Sufentanil) under development is based on our proprietary TRANSDUR transdermal technology and is intended to
provide continuous delivery of sufentanil for up to seven days from a single application, as compared to the two to three days of relief provided by currently available opioid patches. Sufentanil is a highly potent opioid that is currently used in
hospitals as an analgesic for which the patent covering the chemical entity has expired. We anticipate that the small size of our sufentanil patch (potentially as small as 1/5th the size of currently marketed transdermal fentanyl patches for a
therapeutically equivalent dose) and longer duration of delivery may offer improved convenience and compliance for patients.

In March 2005, we entered into an agreement with Endo Pharmaceuticals, Inc. (Endo) granting Endo exclusive rights to develop, market and commercialize TRANSDUR-Sufentanil in the U.S. and Canada. We received an initial payment of
$10.0 million in connection with the execution of the agreement. In February 2009, Endo notified us that it was terminating the license agreement with us, and thereby returning Endos rights to develop and commercialize TRANSDUR-Sufentanil
in the U.S. and Canada to us effective August 26, 2009. We are in active discussions with multiple potential collaborators regarding licensing development and commercialization rights to this program to which we hold worldwide rights.

Clinical Program.    In 2008, Endo successfully completed a Phase II clinical trial for TRANSDUR-
Sufentanil in which they evaluated the conversion of patients on oral and transdermal opioids to TRANSDUR-Sufentanil. This Phase II trial met its primary and secondary objectives of establishing a successful dose-titration regimen and dose potency
relationships, demonstrating safety and tolerability at the therapeutic dose, and achieving effective analgesic pain control. The Phase II data, extensive non-clinical data that had been generated by Endo and detailed proposed protocols for Phase
III were reviewed with the FDA at an end-of-Phase II

meeting on February 19, 2009. As a result of that meeting, we believe we understand the anticipated regulatory pathway for the Phase III program and approval, which will follow a 505(b)2
pathway as discussed with FDA. This pathway would allow us to reference third-party data, potentially reducing time and expense.

ORADUR-ADHD Program

Market Opportunity.    Attention Deficit Hyperactivity Disorder
(ADHD) is a neurobehavioral condition that is estimated to affect approximately 8% of U.S. children ages 4-17, according to the U.S. Centers for Disease Control and Prevention (the CDC). The principal characteristics of ADHD are
inattention, hyperactivity, and impulsivity. The condition presents itself in childhood and can be life long as 65% of children with ADHD continue to present symptoms as adults. Over 50% of children with ADHD are currently treated with stimulants
such as amphetamine or methylphenidate and sales of ADHD treatments were approximately $4.0 billion in 2008. The National Survey on Drug Use & Health estimates that 1.4 million Americans over the age of 12 abuse stimulants for euphoric
highs and increased performance or wakefulness.

Development Strategy.    We are developing a drug
candidate (ORADUR-ADHD) based on DURECTs ORADUR Technology for the treatment of ADHD. This drug candidate is intended to provide once-a-day dosing with added tamper resistant characteristics to address common methods of abuse and misuse of
these types of drugs. In August 2009, we entered into a development and license agreement with Orient Pharma Co., Ltd., a diversified multinational pharmaceutical, healthcare and consumer products company with headquarters in Taiwan, under which we
granted to Orient Pharma development and commercialization rights in certain defined Asian and South Pacific countries toORADUR-ADHD. DURECT retains rights to North America, Europe, Japan and all other countries not specifically licensed to Orient
Pharma. Under our agreement with Orient Pharma, the parties will collaborate to perform a clinical development program through a Phase II study intended to produce a data package suitable for further development of the drug candidate by us as well
as Orient Pharma in their respective territories. We will be responsible for formulation and study design of the Phase I and Phase II clinical program which Orient Pharma has agreed to fund and execute. Orient Pharma would be responsible for all
remaining development and commercialization activities for ORADUR-ADHD in the licensed territory. If commercialized, we will be entitled to receive a royalty on sales of ORADUR-ADHD by Orient Pharma. Orient Pharma has committed to supply a portion
of DURECTs commercial requirements for ORADUR-ADHD in all territories other than the U.S. We anticipate commencing Phase I studies in 2010.

Biologics Programs

The proteins and genes identified by the biotechnology
industry are large, complex, intricate molecules, and many are unsuitable as drugs. If these molecules are given orally, they are often digested before they can have an effect; if given by injection, they may be destroyed by the bodys natural
processes before they can reach their intended sites of action. The bodys natural elimination processes require frequent, high dose injections that may result in unwanted side effects. As a result, the development of biotechnology molecules
for the treatment of human diseases has been limited, and advanced drug delivery systems such as we possess are required to realize the full potential of many of these protein and peptide drugs. We have active programs underway to apply our drug
delivery systems to various biotechnology drugs and drug candidates, and have entered into a number of feasibility studies with biotechnology and pharmaceutical companies to test their products in our systems.

Research Programs in other Therapeutic Categories

We have underway a number of research programs covering medical diseases and conditions other than pain. Such programs include various diseases and disorders including schizophrenia, and cancer. In
conducting our research programs and determining which particular efforts to prioritize for formal development, we employ a rigorous opportunity assessment process that takes into account the unmet medical need, commercial opportunity, technical
feasibility, clinical viability, intellectual property considerations, and the development path including costs to achieve various critical milestones.

Industry Background

Chronic Diseases and Conditions

Although the pharmaceutical, biotechnology
and medical device industries have played key roles in increasing life expectancy and improving health, many chronic, debilitating diseases continue to be inadequately addressed with current drugs or medical devices. Cardiovascular disease, cancer,
neurodegenerative diseases, diabetes, arthritis, epilepsy and other chronic diseases claim the lives of millions of Americans each year. These illnesses are prolonged, are rarely cured completely, and pose a significant societal burden in mortality,
morbidity and cost. The CDC estimates that the major chronic diseases are responsible for approximately 1.7 million deaths annually, or 70% of all deaths in the U.S. Chronic diseases cause major limitations in daily living for more than
25 million Americans. These diseases account for more than 70% of the $1 trillion spent on health care each year in the U.S. Demographic trends suggest that, as the U.S. population ages, the cost of treating chronic diseases will increase.

Current Approaches to Treatment

Drugs are available to treat many chronic diseases, but harmful side effects can limit prolonged treatment. In addition, patients with chronic diseases commonly take multiple medications, often several
times a day, for the remainder of their lives. If patients fail to take drugs as prescribed, they often do not receive the intended benefits or may experience side effects, which are harmful or decrease quality of life. These problems become more
common as the number of drugs being taken increases, the regimen of dosing becomes more complicated, or the patient ages or becomes cognitively impaired. It is estimated that only half of prescribed medicines are taken correctly.

The Pharmaceutical Industry.    The pharmaceutical industry has traditionally focused on the chemical structure
of small molecules to create drugs that can treat diseases and medical conditions. The ability to use these molecules as drugs is based on their potency, safety and efficacy. Therapeutic outcome and ultimately the suitability of a molecule as a drug
depends to a large extent on how it gets into the body, distributes throughout the body, reacts with its intended site of action and is eliminated from the body. However, small molecules can act in diverse tissues throughout the body resulting in
unwanted side effects.

Most drugs require a minimum level in blood and tissues to have significant therapeutic effects. Above
a maximum level, however, the drug becomes toxic or has some unwanted side effects. These two levels define the therapeutic range of the drug. With conventional oral dosing and injections, typically a large quantity of drug is administered to the
patient at one time, which results in high blood levels of drug immediately after dosing. Because of these high levels, the patient can be over-medicated during the period immediately following dosing, resulting in wasted drug and possible side
effects. Due to distribution processes and drug clearance, the blood level of drug falls as time elapses from the last dose. For some duration, the patient is within the desired therapeutic range of blood levels. Eventually, the blood level of drug
falls sufficiently such that the patient becomes under-medicated and experiences little or no drug effect until the next dose is administered.

The Biotechnology Industry.    Over the past twenty-five years, the biotechnology revolution and the expanding field of genomics have led to the discovery of huge numbers of
proteins and genes. Tremendous resources have been committed in the hope of developing drug therapies that would better mimic the bodys own processes and allow for greater therapeutic specificity than is possible with small molecule drugs.
Unfortunately, this huge effort has led to only a limited number of therapeutic products. The proteins and genes identified by the biotechnology industry are large, complex, intricate molecules, and many are unsuitable as drugs. If these molecules
are given orally, they are often digested before they can have an effect; if given by injection, they may be destroyed by the bodys natural processes before they can reach their intended sites of action. The bodys natural elimination
processes require frequent, high dose injections that may result in unwanted side effects. As a result, the development of biotechnology molecules for the treatment of human diseases has been limited.

The Drug Delivery Industry.    In the last thirty-five years, a
multibillion dollar drug delivery industry has developed on the basis that medicine can be improved by delivering drugs to patients in a precise, controlled fashion. Several commercially successful oral controlled release products, transdermal
controlled release patches, and injectable controlled release formulations have been developed. These products demonstrate that the delivery system can be as important to the ultimate therapeutic value of a pharmaceutical product as the active
molecule or compound itself. However, drug delivery products on the market today can still be improved, for example, by providing reduced abuse potential, targeted delivery to minimize systemic effects and longer delivery durations where useful.
Furthermore, traditional drug delivery products are generally not capable of administering biotechnology agents such as proteins and peptides.

The DURECT Solution: Pharmaceutical Systems

We are developing and commercializing pharmaceutical systems that
will deliver the right drug to the right place, in the right amount and at the right time to treat chronic and episodic diseases and conditions. Our pharmaceutical systems enable optimized therapy for a given disease or patient population by
controlling the rate and duration of drug administration. In addition, if advantageous for the therapy, our pharmaceutical systems can target the delivery of the drug to its intended site of action.



| |  |  | The Right Drug: By precisely controlling the dosage or targeting delivery to a specific site, we can expand the therapeutic use of compounds that would
otherwise be too potent to be administered systemically, do not remain in the body long enough to be effective, or have significant side effects when administered systemically. This flexibility allows us to work with a variety of drug candidates
including small molecules, proteins, peptides or genes.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | The Right Place: In addition to enabling systemic delivery, if advantageous for the therapy, with precise placement of our proprietary catheters or
biodegradable drug delivery formulations, we can design our pharmaceutical systems to deliver drugs directly to the intended site of action. This can ensure that the drug reaches the target tissue in effective concentrations, eliminate many side
effects caused by delivery of the drug to unintended sites in the body, and reduce the total amount of drug administered to the body.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | The Right Amount: Our pharmaceutical systems can automatically deliver drug dosages continuously within the desired therapeutic range for the duration
of the treatment period, from days to up to months, without the fluctuations in drug levels typically associated with conventional pills or injections. This can reduce side effects, eliminate gaps in drug therapy, conveniently ensure accurate dosing
and patient compliance, and may reduce the total amount of drug administered to the body.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | The Right Time: Our pharmaceutical systems technologies are designed to minimize the need for intervention by the patient or care-giver and to enhance
dosing compliance. In addition to reducing the cost of care, continuous drug therapy frees the patient from repeated treatment or hospitalization, improving convenience and quality of life. Our systems are well-suited to deliver drug for the right
period of time for the intended indication, whether for hours or days for acute indications or months or years for treating chronic, debilitating diseases such as chronic pain, cancer, heart disease, and neurodegenerative diseases. We believe that
it is more effective to treat chronic diseases with continuous, long-term therapy than with alternatives such as multiple conventional injections or oral dosage forms that create short-term effects.

DURECT Pharmaceutical Systems Technology

Our pharmaceutical systems combine engineering with proprietary small molecule pharmaceutical and biotechnology drug formulations to yield proprietary delivery technologies and products. Through this
combination, we are able to control the rate and duration of drug administration, as well as, when desired, target the delivery of the drug to its intended site of action, allowing our pharmaceutical systems to meet the special

##### Table of Contents

challenges associated with treating medical conditions over an extended period of time. Our pharmaceutical systems can enable new drug therapies or optimize existing therapies based on a broad
range of compounds, including small molecule pharmaceuticals as well as biologics such as proteins, peptides and genes.

Our
pharmaceutical systems are suitable for providing long-term drug therapy because they store highly concentrated, stabilized drugs in a small volume and can protect the drug from degradation by the body. This, in combination with our ability to
continuously deliver precise and accurate doses of a drug, allows us to extend the therapeutic value of a wide variety of drugs, including those which would otherwise be ineffective, too unstable, too potent or cause adverse side effects. In some
cases, delivering the drug directly to the intended site of action can improve efficacy while minimizing unwanted side effects elsewhere in the body, which often limit the long-term use of many drugs. Our pharmaceutical systems can thus provide
better therapy for chronic diseases or conditions, or for certain acute conditions where longer drug dosing is required or advantageous, by replacing multiple injection therapy or oral dosing, improving drug efficacy, reducing side effects and
ensuring dosing compliance. Our pharmaceutical systems can improve patients quality of life by eliminating more repetitive treatments, reducing dependence on caregivers and allowing patients to lead more independent lives.

We currently have six major technology platforms:

The SABER Delivery System

The SABER system is a patented
controlled-release technology that can be formulated for systemic or local administration of active agents via the parenteral or oral route. We are researching and developing a variety of controlled-release products based on the SABER technology.
These include injectable controlled release products for systemic and local delivery and oral products. We believe that our SABER system can provide the basis for the development of a state-of-the-art biodegradable, controlled-release injectable.
The SABER system uses a high-viscosity base component, such as sucrose acetate isobutyrate (SAIB), to provide controlled release of a drug. When the high viscosity SAIB is formulated with drug, biocompatible excipients and other additives, the
resulting formulation is liquid enough to inject easily with standard syringes and needles. After injection of a SABER formulation, the excipients diffuse away, leaving a viscous depot. Depending on how it is formulated, the SABER system can
successfully deliver therapeutic levels of a wide spectrum of drugs from one day to three months from a single injection. Based on research and development work to date, our SABER technology has shown the following advantages:



| |  |  | Peptide/Protein DeliveryThe chemical nature of the SABER system tends to repel water and body enzymes from its interior and thereby
stabilizes proteins and peptides. For this reason, we believe that the SABER system is well suited as a platform for biotechnology therapeutics based on proteins and peptides.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Less BurstTypically, controlled release injections are associated with an initial higher release of drug immediately after injection (also
called burst). Animal and human studies have shown that injectables based on the SABER technology can be associated with less post-injection burst than is typically associated with other commercially available injectable controlled
release technologies.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | High Drug ConcentrationDrug concentration in a SABER formulation can be as high as 30%, considerably greater than is typical with other
commercially available injectable controlled release technologies. As a result, smaller injection volumes are possible with this technology.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Ease of AdministrationPrior to injection, SABER formulations are fairly liquid and therefore can be injected through small needles.
Additionally, because of the higher drug concentration of SABER formulations, less volume is required to be injected. Small injection volumes and more liquid solutions are expected to result in easier, less painful administration.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Strong Patent ProtectionThe SABER system, SABER-like materials, and various applications of this technology to pharmaceuticals, medical
devices and drug delivery are covered by United States and foreign patents. See Patents, Licenses and Proprietary Rights below.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

##### Table of Contents

| |  |  | Ease of ManufactureCompared to microspheres and other polymer-based controlled release injectable systems, SABER is readily manufacturable
at low cost.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------

The SABER Technology is the basis of POSIDUR, which is in Phase III clinical trials in the
U.S. and Phase II clinical trials in the E.U. In our clinical studies thus far, SABER formulations have been observed to be safe and well-tolerated, and no significant side effects or adverse events were reported.

The TRANSDUR Transdermal Delivery System

Our TRANSDUR technology is a proprietary transdermal delivery system that enables delivery of drugs continuously for up to 7 days. The TRANSDUR technology is the basis for TRANSDUR-Sufentanil for which an
end-of-Phase II meeting with the FDA was held in February 2009, and for which we hold worldwide development and commercialization rights. The TRANSDUR technology is also the basis for ELADUR, which is currently in Phase II testing and which we have
licensed worldwide development and commercialization rights to Alpharma (which was acquired by King in December 2008).

The
ORADUR Sustained Release Gel Cap Technology

We are developing ORADUR sustained release oral technology based on our SABER
technology. We believe that ORADUR can transform short-acting oral capsule dosage forms into sustained release oral products. Products based on our ORADUR technology can take the form of an easy to swallow gelatin capsule that uses a high-viscosity
base component such as sucrose acetate isobutyrate (SAIB) to provide controlled release of active ingredients for a period of 12 to 24 hours of drug delivery. Oral dosage forms based on the ORADUR gel-cap may also have the added benefit of being
less prone to abuse (e.g., by crushing or alcohol or water extraction) than other controlled release dosage forms on the market today. These properties have the potential to make ORADUR-based products an attractive option for pharmaceutical
companies that seek to develop abuse deterrent oral products. The ORADUR technology is the basis of Remoxy, a novel long-acting oral formulation of the opioid oxycodone which is targeted to decrease the potential for oxycodone abuse. In December
2007, Remoxy successfully completed a pivotal Phase III clinical trial. Pain Therapeutics submitted an NDA for Remoxy to the FDA in June 2008, and in August 2008, the NDA was accepted by the FDA and granted priority review. In December 2008, Pain
Therapeutics received a Complete Response Letter for its NDA for Remoxy in which the FDA determined that the NDA was not approved. According to Pain Therapeutics, the FDA indicated that additional non-clinical data will be required to support the
approval of Remoxy but the FDA has not requested or recommended additional clinical efficacy studies prior to approval. King Pharmaceuticals assumed responsibility for further development of Remoxy from Pain Therapeutics in March 2009. On
July 2, 2009, King met with the FDA to discuss the Complete Response Letter. According to King and Pain Therapeutics, the outcome of that meeting provided King with a clearer path forward to resubmit the Remoxy NDA and to address all FDA
comments in the Complete Response Letter. King has recently announced that it has undertaken a likeability study and a pharmacokinetic trial in volunteers and plans to resubmit the NDA in the fourth quarter of 2010.

We also have two other ORADUR-based opioid drug candidates for which Phase I clinical trials have been completed. According to Pain
Therapeutics, the data from these Phase I trials indicate that these drug candidates are safe and well-tolerated with release profiles that appear well suited to use with a chronic pain population. The active ingredients in these two drug candidates
are opioids whose identities have not been publicly disclosed.

We also have an ORADUR-ADHD program in the preclinical /
research stage and we expect to commence Phase I trials in 2010.

The DURIN Biodegradable Implant Technology

Our DURIN technology is a proprietary biodegradable implant that enables parenteral delivery of drugs
from several weeks to six months or more using our LACTEL® brand polymers and co-polymers of lactic and glycolic
acid. The DURIN technology can deliver a wide variety of drugs including small and large molecule

##### Table of Contents

compounds. Our proprietary implant design allows for a variety of possible delivery profiles including constant rate delivery. Because DURIN implants are biodegradable, at the end of its delivery
life, what remains of the DURIN implant is absorbed by the body. The DURIN technology is the basis of Memryte for the treatment of Alzheimers disease, with any future development controlled by Curaxis.

The DUROS Technology

The DUROS system is a miniature drug-dispensing pump which can be as small as a wooden matchstick. We have licensed the DUROS system for specified fields of use from ALZA Corporation (ALZA), pursuant to a
development and commercialization agreement entered into effective April 1998. The DUROS system can be used for therapies requiring systemic or site-specific administration of drug. To deliver drugs systemically, the DUROS system is placed just
under the skin, for example in the inner side of the upper arm, in an outpatient procedure that is completed in just a few minutes using local anesthetic. Removal or replacement of the product is also a simple and quick procedure completed in the
doctors office.

The MICRODUR Biodegradable Microparticulate Technology

Our MICRODUR technology is a patented biodegradable microparticulate depot injectable. We have experience in
microencapsulation of a broad spectrum of drugs using our LACTEL® brand polymers and co-polymers of lactic and
glycolic acid. In our MICRODUR process, both standard and proprietary polymers are used to entrap an active agent in solid matrices or capsules comprising particles generally between 10 and 125 microns in diameter. Through a suitable choice of
polymers and processing, sustained release from a few days to many months can be achieved. As with the DURIN technology, MICRODUR particles degrade fully in the body after the active agent is released. Our range of experience extends from the
manufacturing of the polymer raw material to process and product development, scale-up and cGMP manufacturing.

DURECT Strategy

Our objective is to become a specialty pharmaceutical company by developing, and in the future, commercializing
pharmaceutical systems that address significant medical needs and improve patients quality of life. To achieve this objective, our strategy includes the following key elements:

Focus on Chronic Debilitating Medical Conditions and Certain Local Pain Conditions.    Many of the diseases that
present the greatest challenges to medicine are chronic, debilitating diseases such as chronic pain, CNS disorders, cardiovascular disorders, cancer and degenerative neurological diseases. In addition, we have identified certain local and acute pain
conditions that we believe can be addressed by improved therapeutics. Our initial efforts will focus on using our versatile drug delivery platform technologies to develop products that address these medical conditions.

Minimize Product Development Risk and Speed Time-to-Market.    Initially, we intend to minimize product
development risk and speed time-to-market by using our drug delivery platform technologies to administer drugs for which medical data on efficacy and safety are available. This strategy reduces much of the development risk that is inherent in
traditional pharmaceutical product discovery. We anticipate that we can expand the medical usefulness of existing well-characterized drugs in several ways:



| |  |  | expand uses or create new uses for existing drugs by delivering drugs continuously for convenient long dosing intervals;
| | - |  | ------------------------------------------------------------------------------------------------------------------------



| |  |  | create new uses for drugs which were previously considered to be too potent to be used safely by precisely controlling dosing or by delivering them
directly to the site of action;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | enhance drug performance by minimizing side effects; and
| | - |  | --------------------------------------------------------



| |  |  | expand uses of drugs by delivering them to the target site.
| | - |  | -----------------------------------------------------------

##### Table of Contents

We anticipate that our pharmaceutical systems can be more rapidly developed at lower cost
than comparable products that are developed purely based on chemical solutions to the problems of efficacy, side effects, stability and delivery of the active agent. We believe that our ability to innovate more rapidly will allow us to respond more
quickly to market feedback to optimize our existing pharmaceutical systems or develop line extensions that address new market needs.

Enable the Development of Pharmaceutical Systems Based on Biotechnology and Other New Compounds.    We believe there is a significant opportunity for pharmaceutical systems to add value to therapeutic medicine by
administering biologics, such as proteins, peptides and genes. We believe our technologies will improve the specificity, potency, convenience and cost-effectiveness of proteins, peptides, genes and other newly discovered drugs. Our systems can
enable these compounds to be effectively administered, thus allowing them to become viable medicines. We can address the stability and storage needs of these compounds through our advanced formulation technology and package them in a suitable
pharmaceutical system for optimum delivery. Through continuous administration, the SABER, TRANSDUR, ORADUR, DURIN, DUROS and MICRODUR technology platforms may eliminate or reduce the need for multiple injections of these drugs. In addition, through
precise placement of our proprietary biodegradable drug formulations, proteins and genes can be delivered to specific tissues for extended periods of time, thus ensuring that large molecule agents are present at the desired site of action and
minimizing the potential for adverse side effects elsewhere in the body.

Diversify Risk by Pursuing Multiple Programs in
Development.    In order to reduce the risks inherent in pharmaceutical product development, we have diversified our product pipeline such that, between our own programs and those where we have collaborated, we presently have
one program for which an NDA has been accepted but not approved by the FDA, and for which a Complete Response Letter has been received, and five different disclosed programs in clinical development, including two oral drug candidates, two
transdermal patch candidates and one injectable drug candidate. We believe that having multiple programs in development helps mitigate the negative consequences to us of any setbacks or delays in any one of our programs.

Enable Product Development Through Strategic Collaborations.    We believe that entering into selective
collaborations with respect to our product development programs can enhance the success of our product development and commercialization, mitigate our risk and enable us to better manage our operating costs. Additionally, such collaborations enable
us to leverage investment by our collaborators and reduce our net cash burn, while retaining significant economic rights.

Build Our Own Sales and Marketing Organization.    Our goal is to become a specialty pharmaceutical company where we commercialize products with significant market potential. To that end, we intend, over the
course of a few years, to build up commercial, sales and marketing capability and other required infrastructure in focused specialty areas. We will continue to pursue strategic alliances or collaborations from time to time consistent with our
strategy to leverage the established sales organizations of third-party collaborators to achieve greater market penetration for some of our products than we could on our own. If we choose to enter into third-party collaborations to commercialize our
pharmaceutical systems, we believe we have the flexibility to enter into these alliances under circumstances that allow us to retain greater economic participation because our pharmaceutical systems combine drugs for which medical data on efficacy
and safety are available with proven technology platforms.

Third-Party Collaborations

We have entered into the following agreements in connection with our third party collaborations:

Alpharma Ireland Limited (acquired by King in December 2008).In September 2008, we and Alpharma entered
into a development and license agreement granting Alpharma the exclusive worldwide rights to develop and commercialize ELADUR, our investigational transdermal bupivacaine patch. The agreement became

effective in October 2008. Under the terms of the agreement, upon closing of the transaction, Alpharma paid us an upfront license fee of $20 million, with possible additional payments of up to
$93 million upon the achievement of predefined development and regulatory milestones spread over multiple clinical indications and geographical territories as well as possible additional payments of up to $150 million in
sales-based milestones. If ELADUR is commercialized, we would also receive royalties on product sales. Alpharma will control and fund further development of the program. The term of the agreement will continue on a jurisdiction-by-jurisdiction
basis until the later of fifteen (15) years from the date of first commercial sale of ELADUR or the expiration of patent coverage or data exclusivity in each such jurisdiction. During the term of the agreement, subject to specified conditions,
neither party nor their affiliates may develop or commercialize a transdermal patch containing bupivacaine. Upon expiration of the term of the agreement, the rights and licenses granted to Alpharma will convert to fully paid-up, non-royalty bearing,
perpetual rights and licenses. The agreement provides each party with specified termination rights, including the right of Alpharma to terminate at any time without cause and each party to terminate the agreement upon material breach of the
agreement by the other party. The agreement also contains terms and conditions customary for this type of arrangement, including representations, warranties and indemnities. As a result of the acquisition of Alpharma by King in December 2008, King
assumed Alpharmas rights and obligations under the agreement. As of December 31, 2009, the cumulative aggregate payments received by us under this agreement were $24.9 million.

Nycomed Danmark ApS.    In November 2006, we entered into a collaboration agreement with Nycomed, and this
agreement was amended in February 2010. Under the terms of the amended agreement, we licensed to Nycomed the exclusive commercialization rights to POSIDUR for the European Union (E.U.) and certain other countries. Nycomed paid us an upfront license
fee of $14.0 million in 2006 and an $8.0 million milestone payment in 2007 triggered by achievement of a clinical development milestone, with future potential additional milestone payments of up to $181.0 million upon achievement of defined
development, regulatory and sales milestones. Prior to the February 2010 amendment, the agreement provided for us and Nycomed to jointly direct and equally fund a development program for POSIDUR intended to secure regulatory approval in both the
U.S. and the E.U. After the amendment, we now have final decision-making authority over clinical trials intended for the U.S. registration of POSIDUR. Subject to our right to initiate dispute resolution procedures in specified circumstances, Nycomed
will now have final decision-making authority over clinical trials for the E. U. and other countries licensed to it. We now have funding responsibility for all current and future clinical trials intended for U.S. registration of POSIDUR and,
commencing April 1, 2010, Nycomed will have sole funding responsibility for all clinical trials intended for E.U. registration of POSIDUR. The final decision making authority and financial responsibility for the remainder of the development
activities, such as the non-clinical and CMC activities, will be jointly managed and funded by us and Nycomed. In addition, we will manufacture and supply the product to Nycomed for commercial sale in the territory licensed to Nycomed. Nycomed will
pay us blended royalties on sales in the defined territory of 15-40% depending on annual sales, as well as a manufacturing markup. We retain full commercial rights to POSIDUR in the U.S., Canada, Japan and certain other countries. The agreement will
continue in effect until terminated. The agreement provides each party with specified termination rights, including the right of each party to terminate the agreement upon material breach of the agreement by the other party. In addition, Nycomed has
the right to terminate the agreement after the expiration of patents covering POSIDUR in all major market countries in the E.U., for adverse product events, and within specified periods after certain clinical trials of POSIDUR. As of
December 31, 2009, the cumulative aggregate payments received by us under this agreement were $34.8 million. In addition, the cumulative aggregate payments paid by us under this agreement to Nycomed were $6.8 million as of December 31,
2009.

Pain Therapeutics, Inc.    In December 2002, we entered into an exclusive agreement with
Pain Therapeutics to develop and commercialize on a worldwide basis oral sustained release, abuse deterrent opioid products incorporating four specified opioid drugs using our ORADUR technology. The agreement also provides Pain Therapeutics with the
exclusive right to commercialize products developed under the agreement on a worldwide basis. In connection with the execution of the agreement, Pain Therapeutics paid us an upfront fee. In November 2005, Pain Therapeutics sublicensed the
commercialization rights to certain products developed under the agreement (including Remoxy) to King. In December 2005, we amended our agreement with Pain

Therapeutics in order to specify our obligations with respect to the supply of key excipients for use in the licensed products. Under the amended agreement, we are responsible for formulation
development, supply of selected key excipients used in the manufacture of licensed product and other specified tasks. We receive reimbursement for our research and development efforts on the licensed products and a manufacturing profit on our supply
of key product excipients to Pain Therapeutics for use in the licensed products. Under the agreement with Pain Therapeutics, subject to and upon the achievement of predetermined development and regulatory milestones for the four drug candidates
currently in development, we are entitled to receive milestone payments of up to $9.3 million in the aggregate. As of December 31, 2009, we had received $1.7 million in cumulative milestone payments. In addition, if commercialized, we will
receive royalties for Remoxy and other licensed products which do not contain an opioid antagonist of between 6.0% to 11.5% of net sales of the product depending on the sales volumes. This agreement can be terminated by either party for material
breach by the other party and by Pain Therapeutics without cause. As of December 31, 2009, the cumulative aggregate payments received by us from Pain Therapeutics under this agreement were $31.2 million.

In March 2009, King assumed the responsibility for further development of Remoxy from Pain Therapeutics. As a result of this change, we will
continue to perform Remoxy related activities in accordance with the terms and conditions set forth in the license agreement between us and Pain Therapeutics, but with King substituted in lieu of Pain Therapeutics with respect to interactions with
us in our performance of those activities including the obligation to pay us with respect to all Remoxy related costs incurred by us. The cumulative aggregate payments received by us from King as of December 31, 2009 were $811,000 under this
agreement.

During 2008, we began to manufacture commercial lots of certain key excipients that are included in Remoxy to meet
the anticipated requirements for these components. In addition, during the second, third and fourth quarters of 2008 and the first quarter of 2009, we made shipments of these materials to meet the production requirements of King, which has rights to
commercialize Remoxy upon approval by the FDA. During these periods, all product revenue and associated cost of goods sold was deferred pending the establishment of definitive final terms and conditions even though cash receipts and expenditures
occurred during these periods.

In August 2009, we entered into an exclusive long term excipient supply agreement with respect
to REMOXY with King. This agreement stipulates the terms and conditions under which we will supply to King, based on our manufacturing cost plus a specified percentage mark-up, two key excipients used in the manufacture of REMOXY. The term of the
agreement commenced on August 5, 2009 and will continue in effect until the earlier of the expiration of all licenses granted under the development and license agreement between the us and Pain Therapeutics or the termination or expiration of
the 2005 development and license agreement between Pain Therapeutics and King, unless the agreement is terminated earlier in accordance with its terms. The agreement provides each party with specified termination rights, which include, but are not
limited to, the right of King to terminate the agreement in the event that governmental action requires the withdrawal of REMOXY from all countries in the territory or results in the withdrawal of required manufacturing approvals, or upon a change
of control of us, in which case termination will be effective one year after notice by King. We may terminate the agreement if we are unable to procure suitable and sufficient quantities of certain raw materials required to produce the excipient
ingredients. Each party may terminate the agreement upon material breach of the agreement by, or the bankruptcy or insolvency of, the other party, in each case subject to a cure period. The agreement further specifies the rights and obligations of
us and King with respect to plant allocation, adding additional production capacity and sourcing of raw materials, as well as other terms and conditions customary for this type of agreement, including those regarding forecasting, purchasing,
invoicing, representations, warranties and indemnities.

Endo Pharmaceuticals Inc.
(TRANSDUR-Sufentanil).On March 10, 2005, we entered into a license agreement with Endo under which we granted to Endo the exclusive right to develop, market and commercialize TRANSDUR-Sufentanil in the U.S. and
Canada. We received an initial payment of $10.0 million in connection with the execution of the agreement. In February 2009, Endo notified us that it was terminating the license agreement with us, and thereby returned their right to develop and
commercialize TRANSDUR-Sufentanil in the

U.S. and Canada to us effective August 26, 2009. As of December 31, 2009, the cumulative aggregate payments received by us under this agreement were $21.5 million.

Curaxis Pharmaceutical Corporation (formerly Voyager Pharmaceutical Corporation).    In July 2002, we entered
into a development and commercialization agreement with Voyager Pharmaceutical Corporation (now Curaxis). Under the terms of the agreement, as amended in January 2007, we have licensed Curaxis world-wide rights to develop a product using our DURIN
technology to provide sustained release of leuprolide based on Curaxiss patented method of treatment of Alzheimers disease. The amended agreement also provides Curaxis with the right to commercialize the resulting product on a worldwide
basis. We are responsible for preclinical development, product manufacture and other specified tasks. Under the amended agreement, subject to and upon the achievement of predetermined development and regulatory milestones, we are entitled to receive
milestone payments from Curaxis of up to $3.0 million in the aggregate. As of December 31, 2009, we had received $500,000 in cumulative milestone payments. We are also entitled to receive reimbursement for any research and development work we
perform. If Memryte is commercialized, we will receive royalties based on product sales of between ten to fourteen percent (10-14%) of the net sales of Memryte. In addition, we are entitled to receive ten percent (10%) of any upfront, milestone
and other fees received by Curaxis in the event that Memryte is sublicensed to a third party. This agreement can be terminated by either party for material breach by the other party. As of December 31, 2009, the cumulative aggregate payments
received by us under this agreement were $11.6 million. Development of Memryte has been halted pending raising of additional funds by Curaxis.

ALZA Corporation.    In April 1998, we entered into a development and commercialization agreement with ALZA, which has been subsequently amended and restated, most recently in
October 2002. The agreement provides us with exclusive rights to develop, commercialize and manufacture products using ALZAs patented DUROS technology in selected fields of use, and obligates us to pay ALZA a royalty on the net sales of our
DUROS-based products and a percentage of upfront license fees, milestone payments, or any other payments or consideration received by us with respect to such DUROS-based products. This agreement can be terminated by either party for material breach
by the other party and by us without cause.

EpiCept Corporation.In December 2006, we
entered into a license agreement with EpiCept Corporation (EpiCept) that provides us with the exclusive, worldwide license to certain of EpiCepts intellectual property for a transdermal patch containing bupivacaine for the treatment of back
pain. In September 2008, the license was converted to an exclusive, worldwide, fully paid up, royalty-free, perpetual and irrevocable license for a transdermal patch containing bupivacaine under all fields of use covered by the EpiCept intellectual
property. In consideration of the license, we paid EpiCept a cumulative amount of $3.25 million in full satisfaction of all future payment obligations to EpiCept under the license agreement.

NeuroSystec Corporation.    In May 2004, we entered into an exclusive license agreement with NeuroSystec
Corporation (NeuroSystec), a privately-held corporation founded by Alfred E. Mann, under which we granted to NeuroSystec exclusive worldwide rights to develop and commercialize products designed for the treatment of tinnitus and to improve
post-operative recovery and tolerance of surgical implantation of cochlear devices using specified DURECT proprietary drug treatment methods and drug delivery technologies to deliver precise doses of appropriate medications directly to the middle or
inner ear. The first development product is currently in early clinical development. We are responsible for formulation development of products utilizing our drug delivery platforms and manufacture and supply of product components consisting of our
drug delivery platforms. We will receive certain milestone payments if certain development and commercialization milestones are achieved, as well as royalties based on product sales if products are commercialized under the agreement. This agreement
will remain in effect until the expiration of NeuroSystecs royalty obligations under the agreement, which will occur when the last of our related patent rights expire or are found to be invalid, unless the agreement is otherwise terminated
earlier. This agreement can be terminated by either party for material breach by the other party and by NeuroSystec without cause. In connection with the agreement, we received a minority equity ownership interest in NeuroSystec.

Commercial Businesses

ALZET®

We currently make and sell the ALZET
product line on a worldwide basis. We market the ALZET product line through a direct sales force in the U.S. and through a network of distributors outside the U.S.

The ALZET product line consists of miniature, implantable osmotic pumps and accessories used for experimental research in mice, rats and other laboratory animals. These pumps are neither approved nor
intended for human use. ALZET pumps continuously deliver drugs, hormones and other test agents at controlled rates from one day to four weeks without the need for external connections, frequent handling or repeated dosing. In laboratory research,
these infusion pumps can be used for systemic administration when implanted under the skin or in the body. They can be attached to a catheter for intravenous, intracerebral, or intra-arterial infusion or for targeted delivery, where the effects of a
drug or test agent are localized in a particular tissue or organ. The wide use and applications of the ALZET product line is evidenced by the more than 11,000 scientific references that now exist.

We acquired the ALZET product line and assets used primarily in the manufacture, sale and distribution of this product line from ALZA in
April 2000. We believe that the ALZET business provides us with innovative design and application opportunities for potential new products.

LACTEL® Absorbable Polymers

We currently design, develop and manufacture a wide range of standard and custom biodegradable polymers based on lactide,
glycolide and caprolactone under the LACTEL® brand for pharmaceutical and medical device clients for use as raw
materials in their products. These materials are manufactured and sold by us directly from our facility in Pelham, Alabama and are used by us and our third-party customers for a variety of controlled- release and medical-device applications,
including several FDA-approved commercial products.

Marketing and Sales

Historically, we have established strategic distribution and marketing alliances for our pharmaceutical systems to leverage the established
sales organizations that certain pharmaceutical companies have in markets we are targeting. However, our goal is to become a specialty pharmaceutical company that commercializes its own products with significant market potential. To that end, we
intend, over the course of a few years, to build up commercial, sales and marketing capability and other required infrastructure in focused specialty areas, although there can be no assurance that we will be able to do so. We will continue to pursue
strategic alliances and collaborators from time to time consistent with our strategy to leverage the established sales organizations of third-party collaborators to achieve greater market penetration for some of our products than we could on our
own. If we choose to enter into third-party collaborations to commercialize our pharmaceutical systems, we believe we have the flexibility to enter into these alliances under circumstances that allow us to retain greater economic participation
because our pharmaceutical systems combine drugs for which medical data on efficacy and safety are available with proven technology platforms.

We market and sell our ALZET product line through a direct sales force in the U.S. and through a network of distributors outside of the U.S. We market and sell our LACTEL product line through a direct
sales force.

Suppliers

We purchase sucrose acetate isobutyrate, a raw material for our ORADUR and SABER-based pharmaceutical systems, including POSIDUR, Remoxy and other ORADUR-based opioid drug candidates licensed to Pain
Therapeutics, pursuant to a supply agreement with Eastman Chemical Company. We purchase sufentanil for TRANSDUR-Sufentanil pursuant to a supply agreement with Mallinckrodt, Inc. We have entered



18

##### Table of Contents

into a supply agreement with Corium International, Inc. for clinical and commercial supplies of ELADUR and a supply agreement with Hospira Worldwide, Inc. for clinical and commercial supplies of
POSIDUR.

Our supply agreement with Eastman Chemical Company requires us to purchase a certain portion of our requirements for
sucrose acetate isobutyrate from Eastman Chemical and obligates us to pay a fee per annum if our purchases do not meet specified sales targets. The agreement may be terminated by either party under certain circumstances, including any material
uncured breach by, or the insolvency, liquidation or bankruptcy of, or similar proceedings involving, the other party.

Our
supply agreement with Mallinckrodt, Inc. requires us to purchase a certain portion of our requirements for sufentanil from Mallinckrodt, and has no other minimum purchase requirements or exclusivity provisions. The initial term of the agreement
expired on September 30, 2009 and is subject to automatic renewal for additional one-year terms unless either party provides one year notice of its intention not to renew the agreement. In addition, either party may terminate the Mallinckrodt
agreement on 30 days notice for any material uncured breach by, or the bankruptcy of or similar proceedings involving, the other party. Finally, we may terminate the Mallinckrodt agreement on 60 days notice if we reasonably determine that the price
being charged by Mallinckrodt is higher than the prevailing price for similar quantities of like grade or quality, or if we cease to develop or commercialize any products incorporating the products we purchase from Mallinckrodt.

We believe that these agreements will provide a sufficient supply of these raw materials and drug product to meet our needs for the
foreseeable future. We do not have in place long term supply agreements with respect to all of the components of any of our pharmaceutical systems, however, and are subject to the risk that we may not be able to procure all required components in
adequate quantities with acceptable quality, within acceptable time frames or at reasonable cost.

Customers

Our product revenues are derived from sale of the ALZET and LACTEL product lines as well as from the sale of certain key excipients that are
included in Remoxy to our customer (King). Until such time that we are able to bring our pharmaceutical systems to market, if at all, we expect this trend to continue. We also receive revenue from collaborative research and development arrangements
with our third-party collaborators. In 2009, King accounted for 41% of our total revenues and no other customers accounted for more than 10% of total revenues. In 2008, revenues from our collaborative agreements with Pain Therapeutics, Endo,
Alpharma, and Nycomed represented 24%, 15%, 13% and 11% of our total revenues, respectively. In 2007, revenues from our collaborative agreements with Nycomed, Pain Therapeutics, and Endo represented 36%, 16% and 16% of our total revenues,
respectively.

At December 31, 2009, Nycomed and King accounted for 39% and 11% of our net accounts receivable,
respectively. At December 31, 2008, Nycomed and Alpharma accounted for 31% and 29% of our net accounts receivable, respectively. At December 31, 2007, Pain Therapeutics, Nycomed and Endo accounted for 36%, 19% and 16% of our net accounts
receivable, respectively.

Manufacturing

The process for manufacturing our pharmaceutical systems is technically complex, requires special skills, and must be performed in a qualified facility. We have contracted with Hospira Worldwide and
Corium International to manufacture clinical and commercial supplies of POSIDUR and ELADUR respectively. In addition, we have a small multi-discipline manufacturing facility in Cupertino, CA that we have used to manufacture research and clinical
supplies of several of our pharmaceutical systems under GMP, including POSIDUR, Remoxy, TRANSDUR-Sufentanil, ELADUR, and Memryte. In the future, we intend to develop additional manufacturing capabilities for our pharmaceutical systems and components
to meet our demands and

##### Table of Contents

those of our third party collaborators by contracting with third party manufacturers and by construction of additional manufacturing space at our current facilities in Cupertino, CA, Vacaville,
CA and Pelham, AL. We manufacture our ALZET product line and certain key components for Remoxy at our Vacaville, CA facility and our LACTEL product line at our Pelham, AL facility.

Patents, Licenses and Proprietary Rights

Our success depends in part on
our ability to obtain patents, to protect trade secrets, to operate without infringing upon the proprietary rights of others and to prevent others from infringing on our proprietary rights. Our policy is to seek to protect our proprietary position
by, among other methods, filing U.S. and foreign patent applications related to our proprietary technology, inventions and improvements that are important to the development of our business. In the fourth quarter of 2007 and first quarter of 2008,
in two separate tranches, we acquired from a third party a portfolio of worldwide patents relating to drug delivery technologies. This portfolio consists of approximately 22 issued and pending U.S. patents and patent applications as well as their
international counterparts. We believe this portfolio will benefit our business by broadening our drug delivery technology base and strengthening our intellectual property position. As of February 26, 2010, we held 58 issued U.S. patents and
371 issued foreign patents (which include granted European patent rights that have been validated in various EU member states). In addition, we have 90 pending U.S. patent applications and have filed 107 patent applications under the Patent
Cooperation Treaty, from which 532 national phase applications are currently pending in Europe, Australia, Japan, Canada and other countries. Our patents expire at various dates starting in 2012.

Proprietary rights relating to our planned and potential products will be protected from unauthorized use by third parties only to the
extent that they are covered by valid and enforceable patents or are effectively maintained as trade secrets. Patents owned by or licensed to us may not afford protection against competitors, and our pending patent applications now or hereafter
filed by or licensed to us may not result in patents being issued. In addition, the laws of certain foreign countries may not protect our intellectual property rights to the same extent as do the laws of the U.S.

The patent positions of biopharmaceutical companies involve complex legal and factual questions and, therefore, their enforceability cannot
be predicted with certainty. Our patents or patent applications, or those licensed to us, if issued, may be challenged, invalidated or circumvented, and the rights granted thereunder may not provide proprietary protection or competitive advantages
to us against competitors with similar technology. Furthermore, our competitors may independently develop similar technologies or duplicate any technology developed by us. Because of the extensive time required for development, testing and
regulatory review of a potential product, it is possible that, before any of our products can be commercialized, any related patent may expire or remain in existence for only a short period following commercialization, thus reducing any advantage of
the patent, which could adversely affect our ability to protect future product development and, consequently, our operating results and financial position.

Because patent applications in the U.S. are maintained in secrecy for at least 18 months after filing and since publication of discoveries in the scientific or patent literature often lag behind actual
discoveries, we cannot be certain that we were the first to make the inventions covered by each of our issued or pending patent applications or that we were the first to file for protection of inventions set forth in such patent applications.

Our planned or potential products may be covered by third-party patents or other intellectual property rights, in which case
we would need to obtain a license to continue developing or marketing these products. Any required licenses may not be available to us on acceptable terms, if at all. If we do not obtain any required licenses, we could encounter delays in product
introductions while we attempt to design around these patents, or could find that the development, manufacture or sale of products requiring such licenses is foreclosed. Litigation may be necessary to defend against or assert such claims of
infringement, to enforce patents issued to us, to protect trade secrets or know-how owned by us, or to determine the scope and validity of the proprietary rights of others. In addition, interference proceedings declared by the U.S. Patent and
Trademark Office (USPTO) may be



20

##### Table of Contents

necessary to determine the priority of inventions with respect to our patent applications. Litigation or interference proceedings could result in substantial costs to and diversion of effort by
us, and could have a material adverse effect on our business, financial condition and results of operations. These efforts by us may not be successful.

We may rely, in certain circumstances, on trade secrets to protect our technology. However, trade secrets are difficult to protect. We seek to protect our proprietary technology and processes, in part, by
confidentiality agreements with our employees and certain contractors. There can be no assurance that these agreements will not be breached, that we will have adequate remedies for any breach, or that our trade secrets will not otherwise become
known or be independently discovered by competitors. To the extent that our employees, consultants or contractors use intellectual property owned by others in their work for us, disputes may also arise as to the rights in related or resulting
know-how and inventions.

Government Regulation

The Food and Drug Administration.    The FDA and comparable regulatory agencies in state and local jurisdictions and in foreign countries impose substantial requirements upon
the clinical development, manufacture and marketing of pharmaceutical products. These agencies and other federal, state and local entities regulate research and development activities and the testing, manufacture, quality control, safety,
effectiveness, labeling, storage, distribution, record keeping, approval, advertising and promotion of our products. We believe that our initial pharmaceutical systems will be regulated as drugs by the FDA rather than as biologics or devices.

The process required by the FDA under the new drug provisions of the Federal Food, Drug and Cosmetics Act (the Act) before
our initial pharmaceutical systems may be marketed in the U.S. generally involves the following:



| |  |  | preclinical laboratory and animal tests;
| | - |  | ----------------------------------------



| |  |  | submission of an Investigational New Drug (IND) application which must become effective before clinical trials may begin;
| | - |  | -------------------------------------------------------------------------------------------------------------------------



| |  |  | adequate and well-controlled human clinical trials to establish the safety and efficacy of the proposed pharmaceutical in our intended use; and
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | FDA approval of a new drug application.
| | - |  | ---------------------------------------

Section 505 of the Act describes three types of new drug applications: (1) an application that contains full reports of investigations of safety and effectiveness (section 505(b)(1));
(2) an application that contains full reports of investigations of safety and effectiveness but where at least some of the information required for approval comes from studies not conducted by or for the applicant and for which the applicant
has not obtained a right of reference (section 505(b)(2)); and (3) an application that contains information to show that the proposed product is identical in active ingredient, dosage form, strength, route of administration, labeling, quality,
performance characteristics and intended use, among other things, to a previously approved product (section 505(j)). A supplement to an application is a new drug application. We expect that most of our drug candidates will be approved by submission
of a new drug application under section 505(b)(2).

The testing and approval process requires substantial time, effort, and
financial resources, and we cannot be certain that any approval will be granted on a timely basis, if at all. Even though several of our pharmaceutical systems utilize active drug ingredients that are commercially marketed in the United States in
other dosage forms, we need to establish safety and effectiveness of those active ingredients in the formulation and dosage forms that we are developing.

Preclinical tests include laboratory evaluation of the product, its chemistry, formulation and stability, as well as animal studies to assess the potential safety and efficacy of the pharmaceutical
system. We then submit the results of the preclinical tests, together with manufacturing information and analytical data, to the FDA as part of an IND, which must become effective before we may begin human clinical trials. Each subsequent new
clinical



21

##### Table of Contents

protocol must also be submitted to the IND. An IND automatically becomes effective 30 days after receipt by the FDA, unless the FDA, within the 30-day time period, raises concerns or questions
about the conduct of the trials as outlined in the IND and imposes a clinical hold. In such a case, the IND sponsor and the FDA must resolve any outstanding concerns before clinical trials can begin. Our submission of an IND may not result in FDA
authorization to commence clinical trials. Further, an independent Institutional Review Board at each medical center proposing to conduct the clinical trials must review and approve any clinical study as well as the related informed consent forms
and authorization forms that permit us to use individually identifiable health information of study participants.

Human
clinical trials are typically conducted in three sequential phases which may overlap:



| |  |  | Phase I:    The drug is initially introduced into healthy human subjects or patients and tested for safety, dosage tolerance,
absorption, metabolism, distribution and excretion.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Phase II:    Involves clinical trials in a limited patient population to identify possible adverse effects and safety risks, to
determine the efficacy of the product for specific targeted diseases and to determine dosage tolerance and optimal dosage.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Phase III:    When Phase II clinical trials demonstrate that a dosage range of the product is effective and has an acceptable
safety profile, Phase III clinical trials are undertaken to further evaluate dosage, clinical efficacy and to further test for safety in an expanded patient population, at multiple, geographically dispersed clinical study sites.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

In the case of products for severe diseases, such as chronic pain, or life-threatening diseases such as
cancer, the initial human testing is often conducted in patients with disease rather than in healthy volunteers. Since these patients already have the target disease or condition, these studies may provide initial evidence of efficacy traditionally
obtained in Phase II trials, and thus these trials are frequently referred to as Phase I/II clinical trials. We cannot be certain that we will successfully complete Phase I, Phase II or Phase III clinical trials of our pharmaceutical systems within
any specific time period, if at all. Furthermore, the FDA or the Institutional Review Board or the sponsor may suspend clinical trials at any time on various grounds, including a finding that the subjects or patients are being exposed to an
unacceptable health risk. During the clinical development of products, sponsors frequently meet and consult with the FDA in order to ensure that the design of their studies will likely provide data both sufficient and relevant for later regulatory
approval; however, no assurance of approvability can be given by the FDA.

The results of product development, preclinical
studies and clinical studies are submitted to the FDA as part of a new drug application, or NDA, for approval of the marketing and commercial shipment of the product. Submission of an NDA requires the payment of a substantial user fee to the FDA,
and although the agency has defined user fee goals for the time in which to respond to sponsor applications, we cannot assure you that the FDA will act in any particular timeframe. The FDA may deny a new drug application if the applicable regulatory
criteria are not satisfied or may require additional clinical data. Even if such data is submitted, the FDA may ultimately decide that the new drug application does not satisfy the criteria for approval. Once issued, the FDA may withdraw product
approval if compliance with regulatory standards is not maintained or if safety problems occur after the product reaches the market. Requirements for additional Phase IV studies (post approval marketing studies) to confirm safety and effectiveness
in a broader commercial use population may be imposed as a condition of marketing approval. In addition, the FDA requires surveillance programs to monitor approved products which have been commercialized, and the agency has the power to require
changes in labeling or to prevent further marketing of a product based on the results of these post-marketing programs. Any comparative claims that we would like to make for our products vis-à-vis other dosage forms or products will need to
be substantiated generally by two adequate and well-controlled head-to-head clinical trials.

Satisfaction of FDA requirements
or similar requirements of state, local and foreign regulatory agencies typically takes several years and the actual time required may vary substantially, based upon the type, complexity and novelty of the pharmaceutical product. Government
regulation may delay or prevent marketing of potential products for a considerable period of time and impose costly procedures upon our activities. We cannot be



22



---

##### Table of Contents

certain that the FDA or any other regulatory agency will grant approval for any of our pharmaceutical systems under development on a timely basis, if at all. Success in preclinical or early stage
clinical trials does not assure success in later stage clinical trials. Data obtained from preclinical and clinical activities is not always conclusive and may be susceptible to varying interpretations which could delay, limit or prevent regulatory
approval. Evolving safety concerns can result in the imposition of new requirements for expensive and time consuming tests, such as for QT interval cardiotoxicity testing. Even if a product receives regulatory approval, the approval may be
significantly limited to specific indications. Further, even after regulatory approval is obtained, later discovery of previously unknown problems with a product may result in restrictions on the product or even complete withdrawal of the product
from the market. Any pharmaceutical systems that we may develop and obtain approval for would also be subject to adverse findings of the active drug ingredients being marketed in different dosage forms and formulations. Delays in obtaining, or
failures to obtain regulatory approvals would have a material adverse effect on our business. Marketing our pharmaceutical systems abroad will require similar regulatory approvals and is subject to similar risks. In addition, we cannot predict what
adverse governmental regulations may arise from future U.S. or foreign governmental action.

Any pharmaceutical systems
manufactured or distributed by us pursuant to FDA approvals are subject to pervasive and continuing regulation by the FDA, including record-keeping requirements and reporting of adverse experiences with the drug. Drug manufacturers and their
subcontractors are required to register their establishments with the FDA and state agencies, and are subject to periodic unannounced inspections by the FDA and state agencies for compliance with good manufacturing practices, which impose procedural
and documentation requirements upon us and our third party manufacturers. We cannot be certain that we or our present or future suppliers will be able to comply with the GMP regulations and other FDA regulatory requirements.

The FDA regulates drug labeling and promotion activities. The FDA has actively enforced regulations prohibiting the marketing of products
for unapproved uses, and federal and state authorities are also actively litigating against sponsors who promote their drugs for unapproved uses under various fraud and abuse and false claims act statutes. We and our pharmaceutical systems are also
subject to a variety of state laws and regulations in those states or localities where our pharmaceutical systems are or will be marketed. Any applicable state or local regulations may hinder our ability to market our pharmaceutical systems in those
states or localities. We are also subject to numerous federal, state and local laws relating to such matters as safe working conditions, manufacturing practices, environmental protection, fire hazard control, and disposal of hazardous or potentially
hazardous substances. We may incur significant costs to comply with such laws and regulations now or in the future.

The
FDAs policies may change and additional government regulations may be enacted which could prevent or delay regulatory approval of our potential pharmaceutical systems. Moreover, increased attention to the containment of health care costs in
the U.S. and in foreign markets could result in new government regulations that could have a material adverse effect on our business. We cannot predict the likelihood, nature or extent of adverse governmental regulation that might arise from future
legislative or administrative action, either in the U.S. or abroad.

On February 6, 2009, the FDA sent letters to
manufacturers of certain opioid drug products, indicating that these drugs will be required to have a Risk Evaluation and Mitigation Strategy (REMS) to ensure that the benefits of the drugs continue to outweigh the risks. The affected opioid drugs
include brand name and generic products and are formulated with the active ingredients fentanyl, hydromorphone, methadone, morphine, oxycodone, and oxymorphone. The FDA has authority to require a REMS under the Food and Drug Administration
Amendments Act of 2007 (FDAAA) when necessary to ensure that the benefits of a drug outweigh the risks.

According to the FDA,
opioid drugs have benefit when used properly and are a necessary component of pain management for certain patients. Opioid drugs have serious risks when used improperly. The FDA, drug manufacturers, and others have taken a number of steps in the
past to prevent misuse, abuse and accidental

overdose of these drugs, including providing additional warnings in product labeling, implementing risk management plans, conducting inter-agency collaborations, and issuing direct communications
to both prescribers and patients. Despite these efforts, the rates of misuse and abuse, and of accidental overdose of opioids, have risen over the past decade. The FDA believes that establishing a REMS for opioids will reduce these risks, while
still ensuring that patients with legitimate need for these drugs will continue to have appropriate access.

According to the
FDA, it recognizes the need to achieve balance between appropriate access and risk mitigation, and believes an effective strategy would benefit from input from industry, patient advocacy groups, the pain and addiction treatment communities, the
general public, and other stakeholders. In the first of a series of meetings with stakeholders, the FDA invited those companies that market the affected opioid drugs to a meeting with the agency on March 3, 2009 to discuss REMS development.
Additional steps will include discussions with other federal agencies and non-government institutions, including patient and consumer advocates, representatives of the pain and addiction treatment communities, other health care professionals, and
other interested parties. The FDA also held a public meeting on May 27 and 28, 2009 to allow for broader public input and participation. On December 4, 2009, FDA held a public meeting with the drug company sponsors to hear from them about
the status of the development of a proposed REMS and their views regarding the specific features of the REMS. Through this process, FDA hopes to gain valuable information that will lead to practical and effective solutions for development of a REMS
and for appropriate use of these opioid drug products.

Many of our drug candidates including Remoxy, our other ORADUR-opioid
drug candidates and TRANSDUR-Sufentanil are subject to the REMS requirement. Until the contours of required REMS programs are established by the FDA and understood by drug developers and marketers such as ourselves and our collaborators, there may
be delays in marketing approvals for these drug candidates. In addition, there may be increased cost, administrative burden and potential liability associated with the marketing and sale of these types of drug candidates subject to the REMS
requirement, which could negatively impact the commercial benefits to us and our collaborators from the sale of these drug candidates.

The Drug Enforcement Administration.    The Drug Enforcement Administration (DEA) regulates chemical compounds as Schedule I, II, III, IV or V substances, with Schedule I substances considered to present
the highest risk of substance abuse and Schedule V substances the lowest risk. Certain active ingredients in TRANSDUR-Sufentanil, and Remoxy and our other ORADUR-based opioid drug candidates, are listed by the DEA as Schedule II under the Controlled
Substances Act of 1970. Consequently, their manufacture, research, shipment, storage, sale and use are subject to a high degree of oversight and regulation. For example, all Schedule II drug prescriptions must be signed by a physician, physically
presented to a pharmacist and may not be refilled without a new prescription. Furthermore, the amount of Schedule II substances we can obtain for clinical trials and commercial distribution is limited by the DEA and our quota may not be sufficient
to complete clinical trials or meet commercial demand. There is a risk that DEA regulations may interfere with the supply of the drugs used in our clinical trials, and, in the future, our ability to produce and distribute our products in the volume
needed to meet commercial demand.

Competition

We may face competition from other companies in numerous industries including pharmaceuticals, medical devices and drug delivery. POSIDUR, TRANSDUR-Sufentanil, ELADUR, Remoxy and the other ORADUR- based
opioid drug candidates licensed to Pain Therapeutics, if approved, will compete with currently marketed oral opioids, transdermal opioids, local anesthetic patches, and implantable and external infusion pumps which can be used for infusion of
opioids and local anesthetics. Products of these types are marketed by Purdue Pharma, King, Knoll, Janssen, Medtronic, Endo, AstraZeneca, Arrow International, Tricumed, I-Flow and others. Numerous companies are applying significant resources and
expertise to the problems of drug delivery and several of these are focusing or may focus on delivery of drugs to the intended site of action, including Alkermes, Pacira Pharmaceuticals, EpiCept, Innocoll, Nektar, NeurogesX, Alexza, I-Flow
(Kimberly-Clark), Javelin

Pharmaceuticals, Cadence Pharmaceuticals, Cumberland Pharmaceuticals, Egalet, Acura and others. Some of these competitors may be addressing the same therapeutic areas or indications as we are.
Our current and potential competitors may succeed in obtaining patent protection or commercializing products before us.

Any
products we develop using our pharmaceutical systems technologies will compete in highly competitive markets. Many of our potential competitors in these markets have greater development, financial, manufacturing, marketing, and sales resources than
we do and we cannot be certain that they will not succeed in developing products or technologies which will render our technologies and products obsolete or noncompetitive. In addition, many of those potential competitors have significantly greater
experience than we do in their respective fields.

|Item 1A. | Risk Factors.
|-------- | -------------

In
addition to the other information in this Form 10-K, a number of factors may affect our business and prospects. These factors include but are not limited to the following, which you should consider carefully in evaluating our business and prospects.

Risks Related To Our Business

Development of our pharmaceutical systems is not complete, and we cannot be certain that our pharmaceutical systems will be able to be commercialized

To be profitable, we or our third-party collaborators must successfully research, develop, obtain regulatory approval for, manufacture,
introduce, market and distribute our pharmaceutical systems under development. For each pharmaceutical system that we or our third-party collaborators intend to commercialize, we must successfully meet a number of critical developmental milestones
for each disease or medical condition targeted, including:



| |  |  | selecting and developing drug delivery platform technology to deliver the proper dose of drug over the desired period of time;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------



| |  |  | determining the appropriate drug dosage for use in the pharmaceutical system;
| | - |  | -----------------------------------------------------------------------------



| |  |  | developing drug compound formulations that will be tolerated, safe and effective and that will be compatible with the system;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------



| |  |  | demonstrating the drug formulation will be stable for commercially reasonable time periods;
| | - |  | -------------------------------------------------------------------------------------------



| |  |  | demonstrating through clinical trials that the drug and system combination is safe and effective in patients for the intended indication; and
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | completing the manufacturing development and scale-up to permit manufacture of the pharmaceutical system in commercial quantities and at acceptable
prices.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------

The time frame necessary to achieve these developmental milestones for any individual product is
long and uncertain, and we may not successfully complete these milestones for any of our products in development. We have not yet selected the drug dosages nor finalized the formulation or the system design of POSIDUR, TRANSDUR-Sufentanil, ELADUR,
our ORADUR-based drug candidates other than Remoxy, and we have limited experience in developing such products. We may not be able to finalize the design or formulation of any of these pharmaceutical systems. In addition, we may select components,
solvents, excipients or other ingredients to include in our pharmaceutical systems that have not been previously approved for use in pharmaceutical products, which may require us or our collaborators to perform additional studies and may delay
clinical testing and regulatory approval of our pharmaceutical systems. Even after we complete the design of a pharmaceutical

system, the pharmaceutical system must still complete required clinical trials and additional safety testing in animals before approval for commercialization. We are continuing testing and
development of our pharmaceutical systems and may explore possible design or formulation changes to address issues of safety, manufacturing efficiency and performance. We and our collaborators may not be able to complete development of any
pharmaceutical systems that will be safe and effective and that will have a commercially reasonable treatment and storage period. If we or our third-party collaborators are unable to complete development of POSIDUR, TRANSDUR-Sufentanil, ELADUR,
Remoxy and our ORADUR-based drug candidates other than Remoxy, or other pharmaceutical systems, we will not be able to earn revenue from them, which would materially harm our business.

We or our third-party collaborators must conduct and satisfactorily complete required laboratory performance and safety testing, animal
studies and clinical trials for our pharmaceutical systems before they can be sold

Before we or our third-party
collaborators can obtain government approval to sell any of our pharmaceutical systems, we or they, as applicable, must demonstrate through laboratory performance studies and safety testing, nonclinical (animal) studies and clinical (human) trials
that each system is safe and effective for human use for each targeted indication. The clinical development status of our most advanced publicly announced development programs is as follows:



| |  |  | RemoxyIn December 2007, Pain Therapeutics and King reported positive results from the pivotal Phase III trial submitted under an approved Special
Protocol Assessment (SPA) with the FDA; the NDA was submitted to the FDA in June 2008, and in August 2008, the NDA was accepted by the FDA and granted priority review. In December 2008, Pain Therapeutics received a Complete Response Letter for its
NDA for Remoxy in which the FDA determined that the NDA was not approved. According to Pain Therapeutics, the FDA indicated that additional non-clinical data would be required to support the approval of Remoxy, but the FDA had not requested or
recommended additional clinical efficacy studies prior to approval. In March 2009, King assumed the responsibility for further development of Remoxy from Pain Therapeutics. In July 2009, King met with the FDA to discuss the Complete Response Letter
for Remoxy. According to King and Pain Therapeutics, the outcome of that meeting provided King with a clearer path forward to resubmit the REMOXY NDA and to address all FDA comments in the Complete Response Letter. King recently announced that it
has undertaken a likeability study and a pharmacokinetic trial in volunteers and plans to resubmit the NDA in the fourth quarter of 2010. There can be no assurance that any resubmission of the NDA by King will be timely or sufficient to gain
approval of Remoxy.

| |  |  | POSIDURA successful Phase IIb clinical trial in hernia surgery was completed and an end-of-Phase II meeting has been held with the FDA. In 2009,
we completed a successful Phase IIb clinical study in 60 shoulder surgery patients, and Nycomed is conducting Phase IIb studies in hysterectomy patients and shoulder surgery patients. These trials are being conducted by Nycomed in a different manner
than U.S. studies and are designed to be suitable for European regulatory approval purposes. In January 2010, we announced that we had commenced BESST (Bupivacaine Effectiveness and Safety in SABER Trial), which is intended to be the pivotal Phase
III clinical trial in the U.S. BESST is an international, multi-center, randomized, double-blind, controlled trial evaluating the safety, efficacy, effectiveness, and pharmacokinetics of POSIDUR in approximately 300 patients undergoing a variety of
general abdominal surgical procedures. There can be no assurance that these trials will be successful. Furthermore, there can be no assurance that our planned development program for POSIDUR will generate data and information that will be deemed
sufficient for marketing approval by the FDA or other regulatory agencies.

| |  |  | TRANSDUR-Sufentanil PatchOur license agreement with Endo to develop and commercialize TRANSDUR-Sufentanil in the U.S. and Canada was terminated
effective August 26, 2009. Prior to the termination of the license agreement, Endo successfully completed a Phase II program for TRANSDUR-Sufentanil in which they evaluated the conversion of patients on oral and transdermal

| | opioids to TRANSDUR-Sufentanil. The most recent Phase II study met its primary and secondary objectives of establishing a successful dose-titration regimen and dose potency relationships,
demonstrating safety and tolerability at the therapeutic dose, and achieving effective analgesic pain control. The Phase II data, extensive non-clinical data that had been generated by Endo and detailed proposed protocols for Phase III were reviewed
with the FDA at an end-of-Phase II meeting on February 19, 2009. As a result of that meeting, we believe we understand the anticipated regulatory pathway for the Phase III program and approval, which will follow a 505(b)2 pathway as discussed
with FDA. This pathway would allow us to reference third-party data, potentially reducing time and expense. There can be no assurance that our planned development program for TRANSDUR-Sufentanil will generate data and information that will be deemed
sufficient for marketing approval by the FDA or other regulatory agencies or that we will be able to find a collaborator with respect to the development and commercialization of this drug candidate.
| | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | ELADUR A Phase IIa clinical trial was completed and positive results were reported in the fourth quarter of 2007. In 2008, we conducted
manufacturing scale-up and processing activities to secure additional supplies for Phase II and Phase III clinical trials, and developed our clinical and regulatory strategy for further development of this program. Effective October 2008, we entered
into a development and license agreement with Alpharma, granting it the exclusive worldwide rights to develop and commercialize ELADUR. Alpharma was acquired by King in December 2008 and, as a result, Alpharmas rights and obligations under the
agreement have now been assumed by King. Our main activities since December 2008 have involved interacting with the King team on details associated with next steps in the clinical program, which King expects to initiate in the first half of 2010.
There can be no assurance that King will be able to successfully develop ELADUR to obtain marketing approval by the FDA or other regulatory agencies.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

We are currently in the clinical, preclinical or research stages with respect to all our other pharmaceutical systems under development. We plan to continue extensive and costly tests, clinical trials and
safety studies in animals to assess the safety and effectiveness of our pharmaceutical systems. These studies include laboratory performance studies and safety testing, clinical trials and animal toxicological studies necessary to support regulatory
approval of development products in the United States and other countries of the world. These studies are costly, complex and last for long durations, and may not yield the data required for regulatory approval. We and our collaborators may not be
permitted to begin or continue our planned clinical trials for our potential pharmaceutical systems. If our trials are permitted, our potential pharmaceutical systems may not prove to be safe or produce their intended effects. In addition, we or our
collaborators may be required by regulatory agencies to conduct additional animal or human studies regarding the safety and efficacy of our pharmaceutical systems which we have not planned or anticipated. For example, according to Pain Therapeutics,
the FDA has indicated that additional non-clinical data will be required prior to regulatory approval for Remoxy. This additional data could delay commercialization of Remoxy and harm our business and financial condition.

The length of clinical trials will depend upon, among other factors, the rate of trial site and patient enrollment and the number of
patients required to be enrolled in such studies. We or our third-party collaborators may fail to obtain adequate levels of patient enrollment in our clinical trials. Delays in planned patient enrollment may result in increased costs, delays or
termination of clinical trials, which could have a material adverse effect on us. In addition, even if we or our third-party collaborators enroll the number of patients we expect in the time frame we expect, such clinical trials may not provide the
data necessary to support regulatory approval for the pharmaceutical systems for which they were conducted. Additionally, we or our third-party collaborators may fail to effectively oversee and monitor these clinical trials, which would result in
increased costs or delays of our clinical trials. Even if these clinical trials are completed, we or our third-party collaborators may fail to complete and submit a new drug application as scheduled.

The FDA may not clear any such application in a timely manner or may deny the application entirely. Data already obtained from preclinical
studies and clinical trials of our pharmaceutical systems do not necessarily predict the results that will be obtained from later preclinical studies and clinical trials. Moreover, preclinical and

clinical data such as ours are susceptible to varying interpretations, which could delay, limit or prevent regulatory approval. A number of companies in the pharmaceutical industry have suffered
significant setbacks in advanced clinical trials, even after promising results in earlier trials. The failure to adequately demonstrate the safety and effectiveness of a pharmaceutical system under development could delay or prevent regulatory
clearance of the potential pharmaceutical system, resulting in delays to the commercialization of our pharmaceutical system, and could materially harm our business. Clinical trials may not demonstrate the sufficient levels of safety and efficacy
necessary to obtain the requisite regulatory approvals for our pharmaceutical systems, and thus our pharmaceutical systems may not be approved for marketing.

Regulatory action or failure to obtain product approvals could delay or limit development and commercialization of our pharmaceutical systems and result in failure to achieve anticipated revenues

The manufacture and marketing of our pharmaceutical systems and our research and development activities are subject to
extensive regulation for safety, efficacy and quality by numerous government authorities in the United States and abroad. We or our third-party collaborators must obtain clearance or approval from applicable regulatory authorities before we or they,
as applicable, can perform clinical trials, market or sell our products in development in the United States or abroad. Clinical trials, manufacturing and marketing of products are subject to the rigorous testing and approval process of the FDA
and equivalent foreign regulatory authorities. In particular, recent recalls of and reported adverse side effects of marketed drugs have made regulatory agencies, including the FDA, increasingly focus on the safety of drug products. Regulatory
agencies are requiring more extensive and ever increasing showings of safety at every stage of drug development and commercialization from initial clinical trials to regulatory approval and beyond. These rigorous and evolving standards may delay and
increase the expenses of our development efforts. The FDA or other foreign regulatory agency may, at any time, halt our and our collaborators development and commercialization activities due to safety concerns, in which case our business will
be harmed. In addition, the FDA or other foreign regulatory agency may refuse or delay approval of our or our collaborators drug candidates for failure to collect sufficient clinical or animal safety data, and require us or our collaborators
to conduct additional clinical or animal safety data which may cause lengthy delays and increased costs to our programs.

The
Federal Food, Drug and Cosmetic Act and other federal, state and foreign statutes and regulations govern and influence the testing, manufacture, labeling, advertising, distribution and promotion of drugs and medical devices. These laws and
regulations are complex and subject to change. Furthermore, these laws and regulations may be subject to varying interpretations, and we may not be able to predict how an applicable regulatory body or agency may choose to interpret or apply any law
or regulation to our pharmaceutical systems. As a result, clinical trials and regulatory approval can take a number of years to accomplish and require the expenditure of substantial resources. We or our third-party collaborators, as applicable, may
encounter delays or rejections based upon administrative action or interpretations of current rules and regulations. We or our third-party collaborators, as applicable, may not be able to timely reach agreement with the FDA on our clinical trials or
on the required clinical or animal data we or they must collect to continue with our clinical trials or eventually commercialize our pharmaceutical systems.

We or our third-party collaborators, as applicable, may also encounter delays or rejections based upon additional government regulation from future legislation, administrative action or changes in FDA
policy during the period of product development, clinical trials and FDA regulatory review. We or our third-party collaborators, as applicable, may encounter similar delays in foreign countries. Sales of our pharmaceutical systems outside the United
States are subject to foreign regulatory standards that vary from country to country.

The time required to obtain approvals
from foreign countries may be shorter or longer than that required for FDA approval, and requirements for foreign licensing may differ from FDA requirements. We or our third-party collaborators, as applicable, may be unable to obtain requisite
approvals from the FDA and foreign regulatory authorities, and even if obtained, such approvals may not be on a timely basis, or they may not cover the clinical uses that we specify. If we or our third-party collaborators, as applicable, fail to
obtain timely clearance or

approval for our development products, we or they will not be able to market and sell our pharmaceutical systems, which will limit our ability to generate revenue.

Many of our drug candidates under development including Remoxy and TRANSDUR-Sufentanil are subject to mandatory Risk Evaluation and
Mitigation Strategy (REMS) programs, a new requirement by the FDA, which could delay the approval of these drug candidates and increase the cost, burden and liability associated with the commercialization of these drug candidates

On February 6, 2009, the FDA sent letters to manufacturers of certain opioid drug products, indicating that these drugs will be required
to have a Risk Evaluation and Mitigation Strategy (REMS) to ensure that the benefits of the drugs continue to outweigh the risks. The affected opioid drugs include brand name and generic products and are formulated with the active ingredients
fentanyl, hydromorphone, methadone, morphine, oxycodone, and oxymorphone. The FDA has authority to require a REMS under the Food and Drug Administration Amendments Act of 2007 (FDAAA) when necessary to ensure that the benefits of a drug outweigh the
risks.

According to the FDA, opioid drugs have benefit when used properly and are a necessary component of pain management
for certain patients. Opioid drugs have serious risks when used improperly. The FDA, drug manufacturers, and others have taken a number of steps in the past to prevent misuse, abuse and accidental overdose of these drugs, including providing
additional warnings in product labeling, implementing risk management plans, conducting inter-agency collaborations, and issuing direct communications to both prescribers and patients. Despite these efforts, the rates of misuse and abuse, and of
accidental overdose of opioids, have risen over the past decade. The FDA believes that establishing a REMS for opioids will reduce these risks, while still ensuring that patients with legitimate need for these drugs will continue to have appropriate
access.

According to the FDA, it recognizes the need to achieve balance between appropriate access and risk mitigation, and
believes an effective strategy would benefit from input from industry, patient advocacy groups, the pain and addiction treatment communities, the general public, and other stakeholders. In the first of a series of meetings with stakeholders, the FDA
invited those companies that market the affected opioid drugs to a meeting with the agency on March 3, 2009 to discuss REMS development. Additional steps will include discussions with other federal agencies and non-government institutions,
including patient and consumer advocates, representatives of the pain and addiction treatment communities, other health care professionals, and other interested parties. The FDA also held a public meeting on May 27 and 28, 2009 to allow for
broader public input and participation. On December 4, 2009, FDA held a public meeting with the drug company sponsors to hear from them about the status of the development of a proposed REMS and their views regarding the specific features of
the REMS. Through this process, the FDA hopes to gain valuable information that will lead to practical and effective solutions for development of a REMS and for appropriate use of these opioid drug products.

Many of our drug candidates including Remoxy, our other ORADUR-opioid drug candidates and TRANSDUR-Sufentanil are subject to the REMS
requirement. Until the contours of required REMS programs are established by the FDA and understood by drug developers and marketers such as ourselves and our collaborators, there may be delays in marketing approvals for these drug candidates. In
addition, there may be increased cost, administrative burden and potential liability associated with the marketing and sale of these types of drug candidates subject to the REMS requirement, which could negatively impact the commercial benefits to
us and our collaborators from the sale of these drug candidates.

We depend to a large extent on third-party collaborators, and we have limited or no
control over the development, sales, distribution and disclosure for our pharmaceutical systems which are the subject of third-party collaborative or license agreements

Our performance depends to a large extent on the ability of our third-party collaborators to successfully develop and obtain approvals for
our pharmaceutical systems. We have entered into agreements with Pain Therapeutics, Nycomed, Alpharma (acquired by King), Orient Pharma and others under which we granted such third parties the right to develop, apply for regulatory approval for,
market, promote or distribute Remoxy and other ORADUR-based products, POSIDUR, ELADUR and other product candidates, respectively, subject to payments to us in the form of product royalties and other payments. We have limited or no control over the
expertise or resources that any collaborator may devote to the development, clinical trial strategy, regulatory approval, marketing or sale of these pharmaceutical systems, or the timing of their activities. Any of our present or future
collaborators may not perform their obligations as expected. These collaborators may breach or terminate their agreement with us or otherwise fail to conduct their collaborative activities successfully and in a timely manner. They may also conduct
their activities in a manner that is different from the manner we would have chosen, had we been developing such pharmaceutical systems ourselves. Further, our collaborators may elect not to develop or commercialize pharmaceutical systems arising
out of our collaborative arrangements or not devote sufficient resources to the development, clinical trials, regulatory approval, manufacture, marketing or sale of these pharmaceutical systems. If any of these events occur, we may not recognize
revenue from the commercialization of our pharmaceutical systems based on such collaborations. In addition, these third parties may have similar or competitive products to the ones which are the subject of their collaborations with us, or
relationships with our competitors, which may reduce their interest in developing or selling our pharmaceutical systems. We may not be able to control public disclosures made by some of our third-party collaborators, which could negatively impact
our stock price.

Our near-term revenues depend on collaboration agreements with other companies. These agreements subject
us to obligations which must be fulfilled and also make our revenues dependent on the performance of such third parties. If we are unable to meet our obligations or manage our relationships with our collaborators under these agreements or enter into
additional collaboration agreements or if our existing collaborations are terminated, our revenues may decrease

Our
near-term revenues are based to a significant extent on collaborative arrangements with third parties, pursuant to which we receive payments based on our performance of research and development activities set forth in these agreements. We may not be
able to fulfill our obligations or attain milestones set forth in any specific agreement, which could cause our revenues to fluctuate or be less than anticipated and may expose us to liability for contractual breach. In addition, these agreements
may require us to devote significant time and resources to communicating with and managing our relationships with such collaborators and resolving possible issues of contractual interpretation which may detract from time our management would
otherwise devote to managing our operations. Such agreements are generally complex and contain provisions that could give rise to legal disputes, including potential disputes concerning ownership of intellectual property under collaborations. Such
disputes can delay or prevent the development of potential new pharmaceutical systems, or can lead to lengthy, expensive litigation or arbitration. In general, our collaboration agreements, including our agreements with Pain Therapeutics with
respect to Remoxy and other ORADUR-based products incorporating specified opioids, Nycomed with respect to POSIDUR, Alpharma (acquired by King) with respect to ELADUR and Orient Pharma with respect to ORADUR-ADHD, may be terminated by the other
party at will or upon specified conditions including, for example, if we fail to satisfy specified performance milestones or if we breach the terms of the agreement.

If any of our collaborative agreements are terminated, our revenues may be reduced or not materialize, and our products in development related to those agreements may not be commercialized.

Our near-term revenues also depend on milestone payments based on achievements by our
third-party collaborators. Failure of such collaborators to attain such milestones would result in our not receiving additional revenues

In addition to payments based on our performance of research and development activities, our revenues also depend on the attainment of milestones set forth in our collaboration agreements. Such milestones
are typically related to clinical trial developments, regulatory approvals or sales accomplishments. To the extent third-party collaborators do not achieve such milestones, we will not receive the associated revenues, which could harm our financial
condition and may cause us to defer or cut-back development activities or forego the exploitation of opportunities in certain geographic territories, any of which could have a material adverse effect on our business.

Our business strategy includes the entry into additional collaborative agreements. We may not be able to enter into additional
collaborative agreements or may not be able to negotiate commercially acceptable terms for these agreements

Our current
business strategy includes the entry into additional collaborative agreements for the development and commercialization of our pharmaceutical systems. The negotiation and consummation of these type of agreements typically involve simultaneous
discussions with multiple potential collaborators and require significant time and resources from our officers, business development, legal, and research and development staff. In addition, in attracting the attention of pharmaceutical and
biotechnology company collaborators, we compete with numerous other third parties with product opportunities as well the collaborators own internal product opportunities. We may not be able to consummate additional collaborative agreements, or
we may not be able to negotiate commercially acceptable terms for these agreements. If we do not consummate additional collaborative agreements, we may have to consume money more rapidly on our product development efforts, defer development
activities or forego the exploitation of certain geographic territories, any of which could have a material adverse effect on our business.

We may have difficulty raising needed capital in the future

Our business
currently does not generate sufficient revenues to meet our capital requirements and we do not expect that it will do so in the near future. We have expended and will continue to expend substantial funds to complete the research, development and
clinical testing of our pharmaceutical systems. We will require additional funds for these purposes, to establish additional clinical- and commercial-scale manufacturing arrangements and facilities and to provide for the marketing and distribution
of our pharmaceutical systems. Additional funds may not be available on acceptable terms, if at all. If adequate funds are unavailable from operations or additional sources of financing, we may have to delay, reduce the scope of or eliminate one or
more of our research or development programs which would materially harm our business, financial condition and results of operations.

We believe that our cash, cash equivalents and investments, will be adequate to satisfy our capital needs for at least the next 12 months. However, our actual capital requirements will depend on many factors, including:



| |  |  | continued progress and cost of our research and development programs;
| | - |  | ---------------------------------------------------------------------



| |  |  | the continuation of our collaborative agreements that provide financial funding for our activities;
| | - |  | ---------------------------------------------------------------------------------------------------

| |  |  | unexpected legal, accounting and other costs and liabilities related to our business.
| | - |  | -------------------------------------------------------------------------------------

We may consume available resources more rapidly than currently anticipated, resulting in the need for additional funding. We may seek to
raise any necessary additional funds through equity or debt financings, convertible debt financings, collaborative arrangements with corporate collaborators or other sources, which may be dilutive to existing stockholders and may cause the price of
our common stock to decline. In addition, in the event that additional funds are obtained through arrangements with collaborators or other sources, we may have to relinquish rights to some of our technologies or pharmaceutical systems that we would
otherwise seek to develop or commercialize ourselves. If adequate funds are not available, we may be required to significantly reduce or refocus our product development efforts, resulting in loss of sales, increased costs, and reduced revenues.

We and our third-party collaborators may not be able to manufacture sufficient quantities of our pharmaceutical systems
and components to support the clinical and commercial requirements of our collaborators and ourselves at an acceptable cost or in compliance with applicable government regulations, and we have limited manufacturing experience

We or our third-party collaborators to whom we have assigned such responsibility must manufacture our pharmaceutical systems and components
in clinical and commercial quantities, either directly or through third parties, in compliance with regulatory requirements and at an acceptable cost. The manufacturing processes associated with our pharmaceutical systems are complex. Except with
respect to Remoxy, we and our third-party collaborators, where relevant, have not yet completed development of the manufacturing process for any pharmaceutical systems or components including POSIDUR, TRANSDUR-Sufentanil, ELADUR, and other
ORADUR-based drug candidates. If we and our third-party collaborators, where relevant, fail to timely complete the development of the manufacturing process for our pharmaceutical systems, we and our third-party collaborators, where relevant, will
not be able to timely produce product for clinical trials and commercialization of our pharmaceutical systems. We have also committed to manufacture and supply pharmaceutical systems or components under a number of our collaborative agreements with
third-party companies. We have limited experience manufacturing pharmaceutical products, and we may not be able to timely accomplish these tasks. If we and our third-party collaborators, where relevant, fail to develop manufacturing processes to
permit us to manufacture a pharmaceutical system or component at an acceptable cost, then we and our third-party collaborators may not be able to commercialize that pharmaceutical system or we may be in breach of our supply obligations to our
third-party collaborators.

Our manufacturing facility in Cupertino is a multi-disciplinary site that we have used to
manufacture only research and clinical supplies of several of our pharmaceutical systems under good manufacturing practices (GMP), including POSIDUR, TRANSDUR-Sufentanil, ELADUR, Remoxy and other ORADUR-based drug candidates. We have not
manufactured commercial quantities of any of our pharmaceutical systems. In the future, we intend to develop additional manufacturing capabilities for our pharmaceutical systems and components to meet our demands and those of our third-party
collaborators by contracting with third-party manufacturers and by construction of additional manufacturing space at our current facilities in Cupertino, CA, Vacaville, CA and Pelham, AL. We have limited experience building and validating
manufacturing facilities, and we may not be able to accomplish these tasks in a timely manner.

##### Table of Contents

If we and our third-party collaborators, where relevant, are unable to manufacture
pharmaceutical systems or components in a timely manner or at an acceptable cost, quality or performance level, and are unable to attain and maintain compliance with applicable regulations, the clinical trials and the commercial sale of our
pharmaceutical systems and those of our third-party collaborators could be delayed. Additionally, we may need to alter our facility design or manufacturing processes, install additional equipment or do additional construction or testing in order to
meet regulatory requirements, optimize the production process, increase efficiencies or production capacity or for other reasons, which may result in additional cost to us or delay production of product needed for the clinical trials and commercial
launch of our pharmaceutical systems and those of our third-party collaborators.

We have entered into a supply agreement with
Corium International, Inc. for clinical and commercial supplies of ELADUR and a supply agreement with Hospira Worldwide, Inc. for clinical and commercial supplies of POSIDUR. These third parties are currently our sole source for drug product
required for development and commercialization of these drug candidates. Furthermore, we and our third-party collaborators, where relevant, may also need or choose to subcontract with additional third-party contractors to perform manufacturing steps
of our pharmaceutical systems or supply required components for our pharmaceutical systems. Where third party contractors perform manufacturing services for us, we will be subject to the schedule, expertise and performance of third parties as well
as incur significant additional costs. Failure of third parties to perform their obligations could adversely affect our operations, development timeline and financial results.

If we or our third-party collaborators cannot manufacture pharmaceutical systems or components in time to meet the clinical or commercial
requirements of our collaborators or ourselves or at an acceptable cost, our operating results will be harmed.

Failure to
comply with ongoing governmental regulations for our pharmaceutical systems could materially harm our business in the future

Marketing or promoting a drug is subject to very strict controls. Furthermore, clearance or approval may entail ongoing requirements for post-marketing studies. The manufacture and marketing of drugs are subject to continuing FDA and
foreign regulatory review and requirements that we update our regulatory filings. Later discovery of previously unknown problems with a product, manufacturer or facility, or our failure to update regulatory files, may result in restrictions,
including withdrawal of the product from the market. Any of the following or other similar events, if they were to occur, could delay or preclude us from further developing, marketing or realizing full commercial use of our pharmaceutical systems,
which in turn would materially harm our business, financial condition and results of operations:



| |  |  | failure to obtain or maintain requisite governmental approvals;
| | - |  | ---------------------------------------------------------------



| |  |  | failure to obtain approvals for clinically intended uses of our pharmaceutical systems under development; or
| | - |  | ------------------------------------------------------------------------------------------------------------



| |  |  | FDA required product withdrawals or warnings arising from identification of serious and unanticipated adverse side effects in our pharmaceutical
systems.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------

Manufacturers of drugs must comply with the applicable FDA good manufacturing practice
regulations, which include production design controls, testing, quality control and quality assurance requirements as well as the corresponding maintenance of records and documentation. Compliance with current good manufacturing practices
regulations is difficult and costly. Manufacturing facilities are subject to ongoing periodic inspection by the FDA and corresponding state agencies, including unannounced inspections, and must be licensed before they can be used for the commercial
manufacture of our development products. We and/or our present or future suppliers and distributors may be unable to comply with the applicable good manufacturing practice regulations and other FDA regulatory requirements. We have not been subject
to a good manufacturing regulation inspection by the FDA relating to our pharmaceutical systems. If we, our third-party collaborators or our respective

##### Table of Contents

suppliers do not achieve compliance for our pharmaceutical systems we or they manufacture, the FDA may refuse or withdraw marketing clearance or require product recall, which may cause
interruptions or delays in the manufacture and sale of our pharmaceutical systems.

We have a history of operating losses,
expect to continue to have losses in the future and may never achieve or maintain profitability

We have incurred
significant operating losses since our inception in 1998 and, as of December 31, 2009, had an accumulated deficit of approximately $313.9 million. We expect to continue to incur significant operating losses over the next several years as we
continue to incur significant costs for research and development, clinical trials, manufacturing, sales, and general and administrative functions. Our ability to achieve profitability depends upon our ability, alone or with others, to successfully
complete the development of our proposed pharmaceutical systems, obtain the required regulatory clearances, and manufacture and market our proposed pharmaceutical systems. Development of pharmaceutical systems is costly and requires significant
investment. In addition, we may choose to license from third parties either additional drug delivery platform technology or rights to particular drugs or other appropriate technology for use in our pharmaceutical systems. The license fees for these
technologies or rights would increase the costs of our pharmaceutical systems.

To date, we have not generated significant
revenue from the commercial sale of our pharmaceutical systems and do not expect to do so in the near future. Our current product revenues are from the sale of the ALZET product line and the sale of LACTEL biodegradable polymers, and from payments
under collaborative research and development agreements with third parties. We do not expect our product revenues to increase significantly in the near future, and we do not expect that collaborative research and development revenues will exceed our
actual operating expenses. We do not anticipate meaningful revenues to derive from the commercialization and marketing of our pharmaceutical systems in development in the near future, and therefore do not expect to generate sufficient revenues to
cover expenses or achieve profitability in the near future.

We may develop our own sales force to market POSIDUR but we
have limited sales experience and may not be able to do so effectively

We may choose to develop our own sales force to
market POSIDUR in the United States if POSIDUR is approved for marketing by the FDA. Developing a sales force will require substantial expenditures. We have limited sales and marketing experience, and may not be able to effectively recruit, train or
retain sales personnel. We may not be able to effectively sell our pharmaceutical systems, if approved, and our failure to do so could limit or materially harm our business.

We and our third-party collaborators may not sell our pharmaceutical systems effectively

We and our third-party collaborators compete with many other companies that currently have extensive and well-funded marketing and sales
operations. Our marketing and sales efforts and those of our third-party collaborations may be unable to compete successfully against these other companies. We and our third-party collaborators, if relevant, may be unable to establish a sufficient
sales and marketing organization on a timely basis, if at all. We and our third-party collaborators, if relevant, may be unable to engage qualified distributors. Even if engaged, these distributors may:



| |  |  | fail to satisfy financial or contractual obligations to us;
| | - |  | -----------------------------------------------------------



| |  |  | fail to adequately market our pharmaceutical systems;
| | - |  | -----------------------------------------------------



| |  |  | cease operations with little or no notice to us;
| | - |  | ------------------------------------------------



| |  |  | offer, design, manufacture or promote competing product lines;
| | - |  | --------------------------------------------------------------



| |  |  | fail to maintain adequate inventory and thereby restrict use of our pharmaceutical systems; or
| | - |  | ----------------------------------------------------------------------------------------------



| |  |  | build up inventory in excess of demand thereby limiting future purchases of our pharmaceutical systems resulting in significant quarter-to-quarter
variability in our sales.

The failure of us or our third-party collaborators to effectively develop, gain regulatory
approval for, sell, manufacture and market our pharmaceutical systems will hurt our business and financial results.

We
rely heavily on third parties to support development, clinical testing and manufacturing of our pharmaceutical systems

We
rely on third-party contract research organizations, service providers and suppliers to provide critical services to support development, clinical testing, and manufacturing of our pharmaceutical systems. For example, we currently depend on
third-party vendors to manage and monitor our clinical trials and to perform critical manufacturing steps for our pharmaceutical systems. These third parties may not execute their responsibilities and tasks competently or in a timely fashion. We
rely on third-parties to manufacture or perform manufacturing steps relating to our pharmaceutical systems or components. We anticipate that we will continue to rely on these and other third-party contractors to support development, clinical
testing, and manufacturing of our pharmaceutical systems. Failure of these contractors to provide the required services in a competent or timely manner or on reasonable commercial terms could materially delay the development and approval of our
development products, increase our expenses and materially harm our business, financial condition and results of operations.

Key components of our pharmaceutical systems are provided by limited numbers of suppliers, and supply shortages or loss of these suppliers could result in interruptions in supply or increased costs

Certain components and drug substances used in our pharmaceutical systems (including POSIDUR, TRANSDUR-Sufentanil, ELADUR, Remoxy and our
other ORADUR-based drug candidates) are currently purchased from a single or a limited number of outside sources. In particular, Eastman Chemical is the sole supplier, pursuant to a supply agreement entered into in December 2005, of our requirements
of sucrose acetate isobutyrate, a necessary component of POSIDUR, Remoxy, our other ORADUR-opioids and certain other pharmaceuticals systems we have under development. The reliance on a sole or limited number of suppliers could result in:



| |  |  | delays associated with redesigning a pharmaceutical system due to a failure to obtain a single source component;
| | - |  | ----------------------------------------------------------------------------------------------------------------



| |  |  | an inability to obtain an adequate supply of required components; and
| | - |  | ---------------------------------------------------------------------



| |  |  | reduced control over pricing, quality and delivery time.
| | - |  | --------------------------------------------------------

We have supply agreements in place for certain components of our pharmaceuticals systems, but do not have in place long term supply
agreements with respect to all of the components of any of our pharmaceutical system candidates. Therefore the supply of a particular component could be terminated at any time without penalty to the supplier. In addition, we may not be able to
procure required components or drugs from third-party suppliers at a quantity, quality and cost acceptable to us. Any interruption in the supply of single source components could cause us to seek alternative sources of supply or manufacture these
components internally. Furthermore, in some cases, we are relying on our third-party collaborators to procure supply of necessary components. If the supply of any components for our pharmaceutical systems is interrupted, components from alternative
suppliers may not be available in sufficient volumes or at acceptable quality levels within required timeframes, if at all, to meet our needs or those of our third-party collaborators. This could delay our ability to complete clinical trials and
obtain approval for commercialization and marketing of our pharmaceutical systems, causing us to lose sales, incur additional costs, delay new product introductions and could harm our reputation.

If we are unable to adequately protect, maintain or enforce our intellectual property
rights or secure rights to third-party patents, we may lose valuable assets, experience reduced market share or incur costly litigation to protect our rights or our third-party collaborators may choose to terminate their agreements with us

Our success will depend in part on our ability to obtain and maintain patents, maintain trade secret protection and
operate without infringing the proprietary rights of others. As of February 26, 2010, we held 58 issued U.S. patents and 371 issued foreign patents (which include granted European patent rights that have been validated in various EU member
states). In addition, we have 90 pending U.S. patent applications and have filed 107 patent applications under the Patent Cooperation Treaty, from which 532 national phase applications are currently pending in Europe, Australia, Japan, Canada and
other countries. Our patents expire at various dates starting in 2012.

Under our agreement with ALZA, we must assign to ALZA
any intellectual property rights relating to the DUROS system and its manufacture and any combination of the DUROS system with other components, active agents, features or processes. In addition, ALZA retains the right to enforce and defend against
infringement actions relating to the DUROS system, and if ALZA exercises these rights, it will be entitled to the proceeds of these infringement actions.

The patent positions of pharmaceutical companies, including ours, are uncertain and involve complex legal and factual questions. In addition, the coverage claimed in a patent application can be
significantly reduced before the patent is issued. Consequently, our patent applications or those that are licensed to us may not issue into patents, and any issued patents may not provide protection against competitive technologies or may be held
invalid if challenged or circumvented. Our competitors may also independently develop products similar to ours or design around or otherwise circumvent patents issued to us or licensed by us. In addition, the laws of some foreign countries may not
protect our proprietary rights to the same extent as U.S. law.

The patent laws of the U.S. have recently undergone changes
through court decisions which may have significant impact on us and our industry. The recent decisions of the U.S. Supreme Court (e.g., KSR v. Telefex, EBay v. MercExchange) and other courts (e.g., In re Seagate) with respect to the
standards of patentability, enforceability, availability of injunctive relief and damages may make it more difficult for us to procure, maintain and enforce patents. In addition, bills are pending before the U.S. Congress that may fundamentally
change the patent laws of the U.S. on issues ranging from priority entitlement, filing and prosecution matters to enforcement and damages. These changes and proposed reforms have introduced significant uncertainty in the patent law landscape and may
potentially negatively impact our ability to procure, maintain and enforce patents to provide exclusivity for our products.

We are party to several collaborative agreements. Our third-party collaborators have entered into these agreements based on the exclusivity that our intellectual property rights confer on the products being developed. The loss or diminution
of our intellectual property rights could result in a decision by our third-party collaborators to terminate their agreements with us. In addition, these agreements are generally complex and contain provisions that could give rise to legal disputes,
including potential disputes concerning ownership of intellectual property and data under collaborations. Such disputes can lead to lengthy, expensive litigation or arbitration requiring us to devote management time and resources to such dispute
which we would otherwise spend on our business. To the extent that our agreements call for future royalties to be paid conditional on our having patents covering the royalty-bearing subject matter, the decision by the Supreme Court in the case of
MedImmune, Inc. v. Genentech, Inc. could encourage our licensees to challenge the validity of our patents and thereby seek to avoid future royalty obligations without losing the benefit of their license. Should they be successful in such a
challenge, our ability to collect future royalties could be substantially diminished.

We also rely upon trade secrets,
technical know-how and continuing technological innovation to develop and maintain our competitive position. We require our employees, consultants, advisors and collaborators to execute appropriate confidentiality and assignment-of-inventions
agreements with us. These agreements typically



38

##### Table of Contents

provide that all materials and confidential information developed or made known to the individual during the course of the individuals relationship with us is to be kept confidential and
not disclosed to third parties except in specific circumstances, and that all inventions arising out of the individuals relationship with us will be our exclusive property. These agreements may be breached, and in some instances, we may not
have an appropriate remedy available for breach of the agreements. Furthermore, our competitors may independently develop substantially equivalent proprietary information and techniques, reverse engineer our information and techniques, or otherwise
gain access to our proprietary technology.

We may be unable to meaningfully protect our rights in trade secrets, technical
know-how and other non-patented technology. We may have to resort to litigation to protect our intellectual property rights, or to determine their scope, validity or enforceability. In addition, interference proceedings declared by the USPTO may be
necessary to determine the priority of inventions with respect to our patent applications. Enforcing or defending our proprietary rights is expensive, could cause diversion of our resources and may not prove successful. Any failure to enforce or
protect our rights could cause us to lose the ability to exclude others from using our technology to develop or sell competing products.

We may be sued by third parties which claim that our pharmaceutical systems infringe on their intellectual property rights, particularly because there is substantial uncertainty about the validity and
breadth of medical patents

We and our collaborators may be exposed to future litigation by third parties based on claims
that our pharmaceutical systems or activities infringe the intellectual property rights of others or that we or our collaborators have misappropriated the trade secrets of others. This risk is exacerbated by the fact that the validity and breadth of
claims covered in medical technology patents and the breadth and scope of trade secret protection involve complex legal and factual questions for which important legal principles are unresolved. Any litigation or claims against us or our
collaborators, whether or not valid, could result in substantial costs, could place a significant strain on our financial resources and could harm our reputation. We also may not have sufficient funds to litigate against parties with substantially
greater resources. In addition, pursuant to our collaborative agreements, we have provided our collaborators with the right, under specified circumstances, to defend against any claims of infringement of the third party intellectual property rights,
and such collaborators may not defend against such claims adequately or in the manner that we would do ourselves. Intellectual property litigation or claims could force us or our collaborators to do one or more of the following, any of which could
harm our business or financial results:



| |  |  | cease selling, incorporating or using any of our pharmaceutical systems that incorporate the challenged intellectual property, which would adversely
affect our revenue;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | obtain a license from the holder of the infringed intellectual property right, which license may be costly or may not be available on reasonable terms,
if at all; or
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | redesign our pharmaceutical systems, which would be costly and time-consuming.
| | - |  | ------------------------------------------------------------------------------

We may be required to obtain rights to certain drugs

Some of the pharmaceutical systems that we may choose to develop may include proprietary drugs to which we do not have commercial rights. To complete the development and commercialization of
pharmaceutical systems containing drugs to which we do not have commercial rights, we will be required to obtain rights to those drugs. We may not be able to do this at an acceptable cost, if at all. If we are not able to obtain required rights to
commercialize certain drugs, we may not be able to complete the development of pharmaceutical systems which require use of those drugs. This could result in the cessation of certain development projects and the potential write-off of certain assets.

Technologies and businesses which we have acquired may be difficult to integrate, disrupt
our business, dilute stockholder value or divert management attention. We may also acquire additional businesses or technologies in the future, which could have these same effects

We may acquire technologies, products or businesses to broaden the scope of our existing and planned product lines and technologies. Future
acquisitions expose us to:



| |  |  | increased costs associated with the acquisition and operation of the new businesses or technologies and the management of geographically dispersed
operations;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the risks associated with the assimilation of new technologies, operations, sites and personnel;
| | - |  | ------------------------------------------------------------------------------------------------



| |  |  | the diversion of resources from our existing business and technologies;
| | - |  | -----------------------------------------------------------------------



| |  |  | the inability to generate revenues to offset associated acquisition costs;
| | - |  | --------------------------------------------------------------------------



| |  |  | the requirement to maintain uniform standards, controls, and procedures; and
| | - |  | ----------------------------------------------------------------------------



| |  |  | the impairment of relationships with employees and customers or third party collaborators as a result of any integration of new management personnel.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------

Acquisitions may also result in the issuance of dilutive equity securities, the incurrence or assumption of
debt or additional expenses associated with the amortization of acquired intangible assets or potential businesses. Past acquisitions, such as our acquisitions of IntraEAR, ALZET, SBS and APT, as well as future acquisitions, may not generate any
additional revenue or provide any benefit to our business.

Some of our pharmaceutical systems contain controlled
substances, the making, use, sale, importation and distribution of which are subject to regulation by state, federal and foreign law enforcement and other regulatory agencies

Some of our pharmaceutical systems currently under development contain, and our products in the future may contain, controlled substances
which are subject to state, federal and foreign laws and regulations regarding their manufacture, use, sale, importation and distribution. The TRANSDUR-Sufentanil patch, Remoxy and our other ORADUR-based drug candidates, and other pharmaceutical
systems we have under development contain active ingredients which are classified as controlled substances under the regulations of the U.S. Drug Enforcement Agency. For our pharmaceutical systems containing controlled substances, we and our
suppliers, manufacturers, contractors, customers and distributors are required to obtain and maintain applicable registrations from state, federal and foreign law enforcement and regulatory agencies and comply with state, federal and foreign laws
and regulations regarding the manufacture, use, sale, importation and distribution of controlled substances. These regulations are extensive and include regulations governing manufacturing, labeling, packaging, testing, dispensing, production and
procurement quotas, record keeping, reporting, handling, shipment and disposal. These regulations increase the personnel needs and the expense associated with development and commercialization of drug candidates including controlled substances.
Failure to obtain and maintain required registrations or comply with any applicable regulations could delay or preclude us from developing and commercializing our pharmaceutical systems containing controlled substances and subject us to enforcement
action. In addition, because of their restrictive nature, these regulations could limit our commercialization of our pharmaceutical systems containing controlled substances. In particular, among other things, there is a risk that these regulations
may interfere with the supply of the drugs used in our clinical trials, and in the future, our ability to produce and distribute our products in the volume needed to meet commercial demand.

Write-offs related to the impairment of long-lived assets and other non-cash charges, as well as stock-based compensation expenses may
adversely impact or delay our profitability

We may incur significant non-cash charges related to impairment write-downs of
our long-lived assets, including goodwill and other intangible assets. We will continue to incur non-cash charges related to



40

##### Table of Contents

amortization of other intangible assets. For example, we had a $13.5 million non-cash write down of deferred royalties and commercial rights related to CHRONOGESIC in the fourth quarter of 2008,
which impacted our financial statements. We are required to perform periodic impairment reviews of our goodwill at least annually. To the extent these reviews conclude that the expected future cash flows generated from our business activities are
not sufficient to recover the cost of our long-lived assets, we will be required to measure and record an impairment charge to write-down these assets to their realizable values. We completed our last review during the fourth quarter of 2009 and
determined that goodwill was not impaired as of December 31, 2009. However, there can be no assurance that upon completion of subsequent reviews a material impairment charge will not be recorded. If future periodic reviews determine that our
assets are impaired and a write-down is required, it will adversely impact or delay our profitability.

Global credit and
financial market conditions could negatively impact the value of our current portfolio of cash equivalents, short-term investments or long-term investments and our ability to meet our financing objectives.

Our cash and cash equivalents are maintained in highly liquid investments with remaining maturities of 90 days or less at the time of
purchase. Our short-term investments consist primarily of readily marketable debt securities with original maturities of greater than 90 days from the date of purchase but less than one year from the balance sheet date. Our long-term investments
consist primarily of readily marketable debt securities with maturities in one year or beyond from the balance sheet date. While as of the date of this filing, we are not aware of any downgrades, material losses, or other significant deterioration
in the fair value of our cash equivalents, short-term investments or long-term investments since December 31, 2009, no assurance can be given that further deterioration in conditions of the global credit and financial markets would not
negatively impact our current portfolio of cash equivalents, short-term investments or long-term investments or our ability to meet our financing objectives.

We depend upon key personnel who may terminate their employment with us at any time, and we may need to hire additional qualified personnel

Our success will depend to a significant degree upon the continued services of key management, technical and scientific personnel, including
Felix Theeuwes, our Chairman and Chief Scientific Officer and James E. Brown, our President and Chief Executive Officer. In addition, our success will depend on our ability to attract and retain other highly skilled personnel. Competition for
qualified personnel is intense, and the process of hiring and integrating such qualified personnel is often lengthy. We may be unable to recruit such personnel on a timely basis, if at all. Our management and other employees may voluntarily
terminate their employment with us at any time. The loss of the services of key personnel, or the inability to attract and retain additional qualified personnel, could result in delays to product development or approval, loss of sales and diversion
of management resources.

We may not successfully manage our company through varying business cycles

Our success will depend on properly sizing our company through growth and contraction cycles caused in part by changing business conditions,
which places a significant strain on our management and on our administrative, operational and financial resources. To manage through such cycles, we must expand or contract our facilities, our operational, financial and management systems and our
personnel. If we were unable to manage growth and contractions effectively our business would be harmed.

Our business
involves environmental risks and risks related to handling regulated substances

In connection with our research and
development activities and our manufacture of materials and pharmaceutical systems, we are subject to federal, state and local laws, rules, regulations and policies governing the use, generation, manufacture, storage, air emission, effluent
discharge, handling and disposal of certain materials, biological specimens and wastes. Although we believe that we have complied with the applicable laws,



41



---

##### Table of Contents

regulations and policies in all material respects and have not been required to correct any material noncompliance, we may be required to incur significant costs to comply with environmental and
health and safety regulations in the future. Our research and development involves the use, generation and disposal of hazardous materials, including but not limited to certain hazardous chemicals, solvents, agents and biohazardous materials. The
extent of our use, generation and disposal of such substances has increased substantially since we started manufacturing and selling biodegradable polymers. Although we believe that our safety procedures for storing, handling and disposing of such
materials comply with the standards prescribed by state and federal regulations, we cannot completely eliminate the risk of accidental contamination or injury from these materials. We currently contract with third parties to dispose of these
substances generated by us, and we rely on these third parties to properly dispose of these substances in compliance with applicable laws and regulations. If these third parties do not properly dispose of these substances in compliance with
applicable laws and regulations, we may be subject to legal action by governmental agencies or private parties for improper disposal of these substances. The costs of defending such actions and the potential liability resulting from such actions are
often very large. In the event we are subject to such legal action or we otherwise fail to comply with applicable laws and regulations governing the use, generation and disposal of hazardous materials and chemicals, we could be held liable for any
damages that result, and any such liability could exceed our resources.

Our corporate headquarters, manufacturing
facilities and personnel are located in a geographical area that is seismically active

Our corporate headquarters, primary
manufacturing facilities and personnel are located in a geographical area that is known to be seismically active and prone to earthquakes. Should such a natural disaster occur, our ability to conduct our business could be severely restricted, and
our business and assets, including the results of our research, development and manufacturing efforts, could be destroyed.

Risks Related
To Our Industry

The market for our pharmaceutical systems is rapidly changing and competitive, and new products or
technologies developed by others could impair our ability to grow our business and remain competitive

The pharmaceutical
industry is subject to rapid and substantial technological change. Developments by others may render our pharmaceutical systems under development or technologies noncompetitive or obsolete, or we may be unable to keep pace with technological
developments or other market factors. Technological competition in the industry from pharmaceutical and biotechnology companies, universities, governmental entities and others diversifying into the field is intense and is expected to increase.

We may face competition from other companies in numerous industries including pharmaceuticals, medical devices and drug
delivery. POSIDUR, TRANSDUR-Sufentanil, ELADUR, Remoxy and other ORADUR-based drug candidates, if approved, will compete with currently marketed oral opioids, transdermal opioids, local anesthetic patches, stimulants, implantable and external
infusion pumps which can be used for infusion of opioids and local anesthetics. Products of these types are marketed by Purdue Pharma, King, Knoll, Janssen, Medtronic, Endo, AstraZeneca, Arrow International, Tricumed, I-Flow, Cumberland
Pharmaceuticals, Covidien, Shire, Johnson & Johnson, Eli Lilly and Novartis. Numerous companies are applying significant resources and expertise to the problems of drug delivery and several of these are focusing or may focus on delivery of
drugs to the intended site of action, including Alkermes, Pacira Pharmaceuticals, EpiCept, Innocoll, Nektar, I-Flow (Kimberly-Clark), NeurogesX, Alexza, Cadence Pharmaceuticals, Javelin Pharmaceuticals, Cumberland Pharmaceuticals, Egalet, Acura and
others. Some of these competitors may be addressing the same therapeutic areas or indications as we are. Our current and potential competitors may succeed in obtaining patent protection or commercializing products before us. Many of these entities
have significantly greater research and development capabilities than we do, as well as substantially more marketing, manufacturing, financial and managerial resources. These entities represent significant competition for us. Acquisitions of, or
investments in, competing pharmaceutical or biotechnology companies by large corporations could increase such competitors financial, marketing, manufacturing and other resources.

##### Table of Contents

We are engaged in the development of novel therapeutic technologies. Our resources are
limited and we may experience technical challenges inherent in such novel technologies. Competitors have developed or are in the process of developing technologies that are, or in the future may be, the basis for competitive products. Some of these
products may have an entirely different approach or means of accomplishing similar therapeutic effects than our pharmaceutical systems. Our competitors may develop products that are safer, more effective or less costly than our pharmaceutical
systems and, therefore, present a serious competitive threat to our product offerings.

The widespread acceptance of therapies
that are alternatives to ours may limit market acceptance of our pharmaceutical systems even if commercialized. Chronic and post-operative pain are currently being treated by oral medication, transdermal drug delivery systems, such as drug patches,
and implantable drug delivery devices which will be competitive with our pharmaceutical systems. These treatments are widely accepted in the medical community and have a long history of use. The established use of these competitive products may
limit the potential for our pharmaceutical systems to receive widespread acceptance if commercialized.

We could be exposed
to significant product liability claims which could be time consuming and costly to defend, divert management attention and adversely impact our ability to obtain and maintain insurance coverage

The testing, manufacture, marketing and sale of our pharmaceutical systems involve an inherent risk that product liability claims will be
asserted against us. Although we are insured against such risks up to an annual aggregate limit in connection with clinical trials and commercial sales of our pharmaceutical systems, our present product liability insurance may be inadequate and may
not fully cover the costs of any claim or any ultimate damages we might be required to pay. Product liability claims or other claims related to our pharmaceutical systems, regardless of their outcome, could require us to spend significant time and
money in litigation or to pay significant damages. Any successful product liability claim may prevent us from obtaining adequate product liability insurance in the future on commercially desirable or reasonable terms. In addition, product liability
coverage may cease to be available in sufficient amounts or at an acceptable cost. An inability to obtain sufficient insurance coverage at an acceptable cost or otherwise to protect against potential product liability claims could prevent or inhibit
the commercialization of our pharmaceutical systems. A product liability claim could also significantly harm our reputation and delay market acceptance of our pharmaceutical systems.

Acceptance of our pharmaceutical systems in the marketplace is uncertain, and failure to achieve market acceptance will delay our ability
to generate or grow revenues

Our future financial performance will depend upon the successful introduction and customer
acceptance of our future products, including POSIDUR, TRANSDUR-Sufentanil, ELADUR, Remoxy and other ORADUR-based drug candidates. Even if approved for marketing, our pharmaceutical systems may not achieve market acceptance. The degree of market
acceptance will depend upon a number of factors, including:



| |  |  | the receipt of regulatory clearance of marketing claims for the uses that we are developing;
| | - |  | --------------------------------------------------------------------------------------------



| |  |  | the establishment and demonstration in the medical community of the safety and clinical efficacy of our products and their potential advantages over
existing therapeutic products, including oral medication, transdermal drug delivery products such as drug patches, or external or implantable drug delivery products; and
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | pricing and reimbursement policies of government and third-party payors such as insurance companies, health maintenance organizations, hospital
formularies and other health plan administrators.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Physicians, patients, payors or the medical community in
general may be unwilling to accept, utilize or recommend any of our products. If we are unable to obtain regulatory approval, commercialize and market our future products when planned and achieve market acceptance, we will not achieve anticipated
revenues.



43

##### Table of Contents

If users of our products are unable to obtain adequate reimbursement from third-party
payors, or if new restrictive legislation is adopted, market acceptance of our products may be limited and we may not achieve anticipated revenues

The continuing efforts of government and insurance companies, health maintenance organizations and other payors of healthcare costs to contain or reduce costs of health care may affect our future revenues
and profitability, and the future revenues and profitability of our potential customers, suppliers and third-party collaborators and the availability of capital. For example, in certain foreign markets, pricing or profitability of prescription
pharmaceuticals is subject to government control. In the United States, recent federal and state government initiatives have been directed at lowering the total cost of health care, and the U.S. Congress and state legislatures will likely continue
to focus on health care reform, the cost of prescription pharmaceuticals and on the reform of the Medicare and Medicaid systems. While we cannot predict whether any such legislative or regulatory proposals will be adopted, the announcement or
adoption of such proposals could materially harm our business, financial condition and results of operations.

The successful
commercialization of our pharmaceutical systems will depend in part on the extent to which appropriate reimbursement levels for the cost of our pharmaceutical systems and related treatment are obtained by governmental authorities, private health
insurers and other organizations, such as HMOs. Third-party payors are increasingly limiting payments or reimbursement for medical products and services. Also, the trend toward managed health care in the United States and the concurrent growth of
organizations such as HMOs, which could control or significantly influence the purchase of health care services and products, as well as legislative proposals to reform health care or reduce government insurance programs, may limit reimbursement or
payment for our products. The cost containment measures that health care payors and providers are instituting and the effect of any health care reform could materially harm our ability to operate profitably.

If we or our third-party collaborators are unable to train physicians to use our pharmaceutical systems to treat patients diseases
or medical conditions, we may incur delays in market acceptance of our products

Broad use of our pharmaceutical systems
will require extensive training of numerous physicians on the proper and safe use of our pharmaceutical systems. The time required to begin and complete training of physicians could delay introduction of our products and adversely affect market
acceptance of our products. We or third parties selling our pharmaceutical systems may be unable to rapidly train physicians in numbers sufficient to generate adequate demand for our pharmaceutical systems. Any delay in training would materially
delay the demand for our pharmaceutical systems and harm our business and financial results. In addition, we may expend significant funds towards such training before any orders are placed for our products, which would increase our expenses and harm
our financial results.

Potential new accounting pronouncements and legislative actions are likely to impact our future
financial position or results of operations

Future changes in financial accounting standards may cause adverse, unexpected
fluctuations in the timing of the recognition of revenues or expenses and may affect our financial position or results of operations. New pronouncements and varying interpretations of pronouncements have occurred with frequency and may occur in the
future and we may make changes in our accounting policies in the future. Compliance with changing regulation of corporate governance and public disclosure may result in additional expenses. Changing laws, regulations and standards relating to
corporate governance and public disclosure, including the Sarbanes-Oxley Act of 2002, new SEC regulations, PCAOB pronouncements and NASDAQ rules, are creating uncertainty for companies such as ours and insurance, accounting and auditing costs are
increasing as a result of this uncertainty and other factors. We are committed to maintaining high standards of corporate governance and public disclosure. As a result, we intend to invest all reasonably necessary resources to comply with evolving
standards, and this investment may result in increased general and administrative expenses and a diversion of management time and attention from revenue-generating activities to compliance activities.

Risks Related To Our Common Stock

Our operating history makes evaluating our stock difficult

Our quarterly and annual results of operations have historically fluctuated and we expect will continue to fluctuate for the foreseeable
future. We believe that period-to-period comparisons of our operating results should not be relied upon as predictive of future performance. Our prospects must be considered in light of the risks, expenses and difficulties encountered by companies
with no approved pharmaceutical products, particularly companies in new and rapidly evolving markets such as pharmaceuticals, drug delivery and biotechnology. To address these risks, we must, among other things, obtain regulatory approval for and
commercialize our pharmaceutical systems, which may not occur. We may not be successful in addressing these risks and difficulties. We may require additional funds to complete the development of our pharmaceutical systems and to fund operating
losses to be incurred in the next several years.

Investors may experience substantial dilution of their investment

Investors may experience dilution of their investment if we raise capital through the sale of additional equity securities or
convertible debt securities or grant additional stock options to employees and consultants. Any sales in the public market of the common stock issuable upon such conversion could adversely affect prevailing market prices for our common stock.

The price of our common stock may be volatile

The stock markets in general, and the markets for pharmaceutical stocks in particular, have experienced extreme volatility that has often
been unrelated to the operating performance of particular companies. These broad market fluctuations may adversely affect the trading price of our common stock.

Price declines in our common stock could result from general market and economic conditions and a variety of other factors, including:



| |  |  | failure of our third-party collaborators (such as Pain Therapeutics or its commercialization sub-licensee King, Nycomed, Alpharma (now owned by King)
and Orient Pharma) to develop and commercialize successfully the respective pharmaceutical systems they are developing;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | adverse results (including adverse events) or delays in our clinical and non-clinical trials of POSIDUR, TRANSDUR-Sufentanil, ELADUR, Remoxy, our other
ORADUR-based drug candidates or other pharmaceutical systems;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | announcements of FDA non-approval of our pharmaceutical systems, or delays in the FDA or other foreign regulatory agency review process;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------



| |  |  | adverse actions taken by regulatory agencies or law enforcement agencies with respect to our pharmaceutical systems, clinical trials, manufacturing
processes or sales and marketing activities, or those of our third party collaborators;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | announcements of technological innovations, patents or new products by our competitors;
| | - |  | ---------------------------------------------------------------------------------------



| |  |  | regulatory developments in the United States and foreign countries;
| | - |  | -------------------------------------------------------------------



| |  |  | any lawsuit involving us or our pharmaceutical systems including intellectual property infringement or product liability suits;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------



| |  |  | announcements concerning our competitors, or the biotechnology or pharmaceutical industries in general;
| | - |  | -------------------------------------------------------------------------------------------------------



| |  |  | developments concerning our strategic alliances or acquisitions;
| | - |  | ----------------------------------------------------------------



| |  |  | actual or anticipated variations in our operating results;
| | - |  | ----------------------------------------------------------

##### Table of Contents

| |  |  | changes in recommendations by securities analysts or lack of analyst coverage;
| | - |  | ------------------------------------------------------------------------------



| |  |  | deviations in our operating results from the estimates of analysts;
| | - |  | -------------------------------------------------------------------



| |  |  | sales of our common stock by our executive officers or directors or sales of substantial amounts of common stock by others;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------



| |  |  | changes in accounting principles; or
| | - |  | ------------------------------------



| |  |  | loss of any of our key scientific or management personnel.
| | - |  | ----------------------------------------------------------

The market price of our common stock may fluctuate significantly in response to factors which are beyond our control. The stock market in
general has recently experienced extreme price and volume fluctuations. In addition, the market prices of securities of technology and pharmaceutical companies have also been extremely volatile, and have experienced fluctuations that often have been
unrelated or disproportionate to the operating performance of these companies. These broad market fluctuations could result in extreme fluctuations in the price of our common stock, which could cause a decline in the value of our common stock.

In the past, following periods of volatility in the market price of a particular companys securities, litigation has
often been brought against that company. If litigation of this type is brought against us, it could be extremely expensive and divert managements attention and our companys resources.

We have broad discretion over the use of our cash and investments, and their investment may not always yield a favorable return

Our management has broad discretion over how our cash and investments are used and may from time to time invest in ways
with which our stockholders may not agree and that do not yield favorable returns.

Executive officers, directors and
principal stockholders have substantial control over us, which could delay or prevent a change in our corporate control favored by our other stockholders

Our directors, executive officers and principal stockholders, together with their affiliates, have substantial control over us. The interests of these stockholders may differ from the interests of other
stockholders. As a result, these stockholders, if acting together, would have the ability to exercise control over all corporate actions requiring stockholder approval irrespective of how our other stockholders may vote, including:



| |  |  | the election of directors;
| | - |  | --------------------------



| |  |  | the amendment of charter documents;
| | - |  | -----------------------------------



| |  |  | the approval of certain mergers and other significant corporate transactions, including a sale of substantially all of our assets; or
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the defeat of any non-negotiated takeover attempt that might otherwise benefit the public stockholders.
| | - |  | -------------------------------------------------------------------------------------------------------



| |  |  | Our certificate of incorporation, our bylaws, Delaware law and our stockholder rights plan contain provisions that could discourage another company
from acquiring us.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Provisions of Delaware law, our certificate of incorporation, bylaws and stockholder rights plan may discourage, delay or prevent a merger or
acquisition that stockholders may consider favorable, including transactions in which you might otherwise receive a premium for your shares. These provisions include:
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | authorizing the issuance of blank check preferred stock without any need for action by stockholders;
| | - |  | ------------------------------------------------------------------------------------------------------



| |  |  | providing for a dividend on our common stock, commonly referred to as a poison pill, which can be triggered after a person or group
acquires 17.5% or more of common stock;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | providing for a classified board of directors with staggered terms;

The closing sale price
of our common stock as reported on the NASDAQ Global Market on February 26, 2010 was $2.39 per share. As of that date there were approximately 139 holders of record of the common stock. This does not include the number of persons whose stock is
in nominee or street name accounts through brokers. The market price of our common stock has been and may continue to be subject to wide fluctuations in response to a number of events and factors, such as progress in our development
programs, quarterly variations in our operating results, announcements of technological innovations or new products by us or our competitors, changes in financial estimates and recommendations by securities analysts, the operating and stock
performance of other companies that investors may deem comparable to us, and news reports relating to trends in our markets. These fluctuations, as well as general economic and market conditions, may adversely affect the market price for our common
stock.

Dividend Policy

We have never paid cash dividends on our common stock. We currently intend to retain any future earnings to fund the development and growth of our business. Therefore, we do not currently anticipate
paying any cash dividends in the foreseeable future.

this Managements Discussion and Analysis of Financial Condition and Results of Operations. These forward-looking statements reflect our view only as of the date of this report. We undertake
no obligations to update any forward-looking statements. You should also carefully consider the factors set forth in other reports or documents that we file from time to time with the Securities and Exchange Commission.

Overview

We are an
emerging specialty pharmaceutical company focused on the development of pharmaceutical systems based on proprietary drug delivery technology platforms. We are developing and commercializing pharmaceutical systems that will deliver the right drug to
the right place in the right amount at the right time to treat chronic or episodic diseases and conditions. By integrating chemistry and engineering advancements, we seek to achieve what drugs or devices alone cannot. Our pharmaceutical systems
enable optimized therapy for a given disease or patient population by controlling the rate and duration of drug administration and providing sustained drug delivery.

In addition to developing our own proprietary products, we enter into strategic collaborations with pharmaceutical companies to develop and commercialize proprietary and enhanced pharmaceutical products
based on our technologies. We have six disclosed on-going product candidates in clinical development.

Collaborative
Research and Development Revenues

Collaborative research and development revenues consist of three broad categories:
(a) the amortization of upfront license payments on a straight-line basis over the period of our continuing involvement with the third party, (b) the reimbursement of qualified research expenses by third parties and (c) milestone
payments in connection with our collaborative agreements. During the last several years, we generated collaborative research and development revenues from collaborative agreements with Endo, Pain Therapeutics, Nycomed, King and others. In contrast
to our other collaborations, due to the terms and nature of the Nycomed collaboration, we do not recognize revenue from the reimbursement of qualified research expenses by Nycomed pursuant to ASC 808-10,Accounting for Collaborative
Arrangements. Rather, we record research and development expense equal to our net share of the joint research and development expenses undertaken under the product development plan.

Product Revenues

We currently generate product revenue from the sale of three product lines:



| |  |  | ALZET® osmotic
pumps for animal research use;
| | - |  | ---------------------------------------------



| |  |  | LACTEL®
biodegradable polymers which are used by our customers as raw materials in their pharmaceutical and medical products; and
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------



| |  |  | certain key excipients that are included in Remoxy.
| | - |  | ---------------------------------------------------

Because we consider our core business to be developing and commercializing pharmaceutical systems, we do not intend to significantly increase our investments in or efforts to sell or market any of our
existing product lines. However, we expect that we will continue to make efforts to increase our revenue related to collaborative research and development by entering into additional research and development agreements with third-party collaborators
to develop product candidates based on our drug delivery technologies.

Reduction In Force

In March 2009, we reduced the size of our California workforce by 41 employees or approximately 24% of our headcount. The goal of this action
was to better align our cost structure with anticipated revenues and operating expenses, while not compromising our key corporate objectives for the year. We substantially completed this headcount reduction during the first quarter of 2009, and
incurred approximately $443,000 in severance costs for the impacted employees in 2009.

Operating Results

Since our inception in 1998, we have had a history of operating losses. At December 31, 2009, we had an accumulated deficit of $313.9
million and our net losses were $30.3 million, $43.9 million and $24.3 million for the years ended December 31, 2009, 2008 and 2007, respectively. These losses have resulted primarily from costs incurred to research and develop our product
candidates and to a lesser extent, from selling, general and administrative costs associated with our operations and product sales. We expect our research and development expenses to increase in the near future as we expect to continue to expand our
clinical trials, nonclinical studies and other research and development activities as well as to incur additional stock-based compensation costs related to research and development personnel. We expect selling, general and administrative expenses to
remain comparable in the near future. We do not anticipate meaningful revenues from our pharmaceutical systems, should they be approved, for at least the next twelve months. Therefore, we expect to incur continuing losses and negative cash flow from
operations for the foreseeable future.

Critical Accounting Policies and Estimates

General

The
preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets
and liabilities at the dates of the financial statements and the reported amounts of revenues and expenses during the reporting periods. The most significant estimates and assumptions relate to revenue recognition, the recoverability of our
long-lived assets, including goodwill and other intangible assets, accrued liabilities, contract research liabilities and stock-based compensation. Actual amounts could differ significantly from these estimates.

Revenue Recognition

Revenue from the sale of products is recognized when there is persuasive evidence that an arrangement exists, the product is shipped and title transfers to customers, provided no continuing obligation exists, the price is fixed or
determinable and the collectibility of the amounts owed is reasonably assured. We recognize revenue from the sale of our products and license and collaboration agreements pursuant to Accounting Standards Codification (ASC) 605, Revenue
Recognition. Multiple element agreements entered into are evaluated under the provision of ASC 605-25, Multiple-Element Arrangements. We evaluate whether there is stand-alone value for the delivered elements and objective and reliable
evidence of fair value for the undelivered element(s) to allocate revenue to each element in multiple element agreements. When the delivered element does not have stand-alone value or there is insufficient evidence of fair value for the undelivered
element(s), we recognize the consideration for the combined unit of accounting in the same manner as the revenue is recognized for the final deliverable, which is generally ratably over the longest period of involvement. Returns or credits related
to the sale of products have not had a material impact on our revenues or net loss.

Upfront payments received upon execution
of collaborative agreements are recorded as deferred revenue and recognized as collaborative research and development revenue based on a straight-line basis over the period of our continuing involvement with the third party collaborator pursuant to
the applicable agreement. Such period generally represents the research and development period set forth in the work plan defined in the respective agreements between us and our third-party collaborators.

Research and development revenue related to services performed under the collaborative arrangements with our corporate collaborators is
recognized as the related research and development services are performed and the collectibility of the amounts owed is reasonably assured. These research payments received under each respective agreement are not refundable and are generally based
on reimbursement of qualified expenses, as defined in the agreements. Research and development expenses under the collaborative research and development agreements generally approximate or exceed the revenue recognized under such agreements over the
term of the respective agreements. Deferred revenue may result when we do not expend the required level of



53

effort during a specific period in comparison to funds received under the respective agreement. Pursuant to ASC 808-10, Collaborative Arrangements, for joint control and funding
development activities, we will not recognize revenue from the reimbursement of the research and development expenses but instead those reimbursements receivable from the joint venture party will be recorded as a reduction in research and
development expense.

Milestone payments under collaborative arrangements are recognized as revenue upon achievement of the
at risk milestone events, which represent the culmination of the earnings process related to that milestone. Milestone payments are triggered either by the results of our research and development efforts or by events external to us, such
as regulatory approval to market a product or the achievement of specified sales levels by a third-party collaborator. As such, the milestones are substantially at risk at the inception of the collaboration agreement, and the amounts of the payments
assigned thereto are commensurate with the milestone achieved. In addition, upon the achievement of a milestone event, we have no future performance obligations related to that milestone payment.

Research and Development Expenses

Research and development expenses are primarily comprised of salaries, benefits, stock based compensation and other compensation cost associated with research and development personnel, overhead and
facility costs, preclinical and non-clinical development costs, clinical trial and related clinical manufacturing costs, contract services, and other outside costs. Research and development costs are expensed as incurred. Research and development
costs paid to third parties under sponsored research agreements are recognized as expense as the related services are performed, generally ratably over the period of service. In addition, reimbursements by Nycomed for research and development
expenses incurred by us are recorded as a reduction to research and development expenses. Research and development expenses incurred by Nycomed and reimbursable by us are recorded as an addition to our research and development expenses in the period
incurred.

Intangible Assets and Goodwill

We record intangible assets when we acquire other companies and intellectual property rights. The cost of an acquisition is allocated to the assets acquired and liabilities assumed, including intangible
assets, with the remaining amount being classified as goodwill. Certain intangible assets such as completed or core technologies are amortized over time.

Goodwill is not amortized to expense but rather periodically assessed for impairment. The allocation of the cost of an acquisition to intangible assets and goodwill therefore has a significant impact on
our future operating results. The allocation process requires the extensive use of estimates and assumptions, including estimates of future cash flows expected to be generated by the acquired assets. We are also required to estimate the useful lives
of those intangible assets subject to amortization, which determines the amount of amortization that will be recorded in a given future period and how quickly the total balance will be amortized. We periodically review the estimated remaining useful
lives of our intangible assets. A reduction in our estimate of remaining useful lives, if any, could result in increased amortization expense in future periods. We assess the impairment of identifiable intangible assets, long-lived assets and
goodwill whenever events or changes in circumstances indicate that the carrying value may not be recoverable. Factors we consider important which could trigger an impairment review include the following:



| |  |  | significant underperformance relative to expected historical or projected future operating results;
| | - |  | ---------------------------------------------------------------------------------------------------



| |  |  | significant changes in the manner of our use of the acquired assets or the strategy for our overall business;
| | - |  | -------------------------------------------------------------------------------------------------------------



| |  |  | significant negative industry or economic trends;
| | - |  | -------------------------------------------------



| |  |  | significant decline in our stock price for a sustained period; and
| | - |  | ------------------------------------------------------------------



| |  |  | our market capitalization relative to net book value.
| | - |  | -----------------------------------------------------

##### Table of Contents

When we determine that the carrying value of intangibles, long-lived assets and goodwill may
not be recoverable based upon the existence of one or more of the above indicators of impairment, we measure any impairment based on a projected discounted cash flow method using a discount rate determined by our management to be commensurate with
the risk inherent in our current business model. The amount of any impairment charge is significantly impacted by and highly dependent upon assumptions as to future cash flows and the appropriate discount rate. Management believes that the discount
rate used in this analysis is reasonable in light of currently available information. The use of different assumptions or discount rates could result in a materially different impairment charge.

We perform a review for impairment of goodwill at least annually in accordance with ASC350, Intangibles  Goodwill and Other. No
impairment of goodwill has been recorded through December 31, 2009. However, there can be no assurance that at the time other periodic reviews are completed, a material impairment charge will not be recorded.

Accrued Liabilities and Contract Research Liabilities

We incur significant costs associated with third party consultants and organizations for pre-clinical studies, clinical trials, contract manufacturing, validation, testing, and other research and
development-related services. We are required to estimate periodically the cost of services rendered but unbilled based on managements estimates of project status. If these good faith estimates are inaccurate, actual expenses incurred could
materially differ from our estimates.

Stock-Based Compensation

Under the provisions of ASC 718, Compensation  Stock Compensation, employee stock-based compensation is estimated at the date
of grant based on the employee stock awards fair value using the Black Scholes option-pricing model and is recognized as expense ratably over the requisite period in a manner similar to other forms of compensation paid to employees.

We estimate the volatility of our common stock at the date of grant based on the historical volatility of our common stock,
consistent with ASC 718, Compensation  Stock Compensation. We base the risk-free rate that we use in the Black-Scholes option valuation model on the implied yield in effect at the time of option grant on U.S. Treasury zero-coupon issues
with equivalent remaining terms. We have never paid any cash dividends on our common stock and we do not anticipate paying any cash dividends in the foreseeable future. Consequently, we use an expected dividend yield of zero in the Black-Scholes
option valuation model. ASC 718 equires us to estimate forfeitures at the time of grant and revise those estimates in subsequent periods if actual forfeitures differ from those estimates. We use historical data to estimate pre-vesting option
forfeitures and record stock-based compensation expense only for those awards that are expected to vest. For options granted before January 1, 2006, we amortize the fair value on an accelerated basis. For options granted on or after
January 1, 2006, we amortize the fair value on a straight-line basis. All options are amortized over the requisite service periods of the awards, which are generally the vesting periods. We may elect to use different assumptions under the
Black-Scholes option valuation model in the future, which could materially affect our net income or loss and net income or loss per share.

Significant Accounting Policies of the Notes to Financial Statements in Item 8. Financial Statements and Supplementary Data for a full description of recent accounting pronouncements including the respective expected dates of adoption

Results of Operations

Comparison of years ended December 31, 2009, 2008 and 2007

Revenues.    Net revenues were $24.3 million in 2009 compared to $27.1 million in 2008. The decrease in total revenues in 2009 was primarily attributable to lower collaborative research and development revenue
recognized from our agreements with Pain Therapeutics, Endo and Nycomed, partially offset by higher collaborative research and development revenue from King, higher product revenue from the sale of our LACTEL biodegradable polymer product line and
revenue from the sale of certain excipients included in Remoxy to King. Revenue in 2009 also included $3.0 million related to shipments to King that occurred in 2008 and the first quarter of 2009 but that had been deferred until a long term supply
agreement was signed such that final terms and conditions of the sales were established. This agreement was executed in the quarter ended September 30, 2009, and all of the deferred revenue was recognized as product revenue in that period.

Net revenues were $27.1 million in 2008 compared to $30.7 million in 2007. We recognized $850,000 of milestone revenue in
2008 from our Pain Therapeutics collaboration as compared to $8.0 million recognized in 2007 from our Nycomed collaboration. Excluding the milestone revenue, total revenue in 2008 increased compared to 2007 primarily due to higher collaborative
research and development revenue recognized from our agreements with Alpharma (acquired by King) and Pain Therapeutics as well as higher product revenue from our ALZET and LACTEL product lines, partially offset by lower collaborative research and
development revenue from Endo and from feasibility agreements with various third parties.

Collaborative research and
development and other revenue

We recognize revenues from collaborative research and development activities and service
contracts. Collaborative research and development revenue primarily represents reimbursement of qualified expenses related to the collaborative agreements with various third parties to research, develop and commercialize potential products using our
drug delivery technologies, amortization of upfront fees and milestone payments associated with the license agreements.

We
recorded $12.2 million of collaborative research and development and other revenue in 2009 compared to $18.3 million in 2008. The decrease in collaborative research and development revenue in 2009 was primarily attributable to lower revenue
recognized in connection with our agreements with Pain Therapeutics and Endo as well as lower amortization of the upfront payment under our agreement with Nycomed, partially offset by higher collaborative research and development revenue recognized
in connection with our agreements with King and other feasibility agreements compared with 2008.

We recorded $18.3 million of
collaborative research and development and other revenue in 2008 compared to $22.4 million in 2007. The decrease in collaborative research and development and other revenue in 2008 was primarily attributable to our recognition in 2007 of $8.0
million of milestone revenue from our Nycomed collaboration related to POSIDUR. Excluding the impact of milestone revenue, collaborative research and development revenue increased in 2008 due to higher revenue recognized in connection with our
agreement with Alpharma (acquired by King) and Pain Therapeutics, partially offset by lower collaborative research and development revenue recognized in connection with our agreement with Endo and from feasibility agreements compared with 2007.

We received a $20.0 million upfront fee in connection with the development and license agreement signed with Alpharma in
September 2008 relating to ELADUR. The $20.0 million upfront fee is recognized as collaborative research and development revenue ratably over the term of our continuing involvement with Alpharma with respect to ELADUR. Our estimate of the remaining
term of our continuing involvement was modified in the second quarter of 2009 as a result of an updated development plan for ELADUR.

We also received a $14.0 million upfront fee in connection with the development and license agreement signed with Nycomed in November 2006 relating to POSIDUR. The $14.0 million upfront fee is recognized as



56

##### Table of Contents

collaborative research and development revenue ratably over the term of our continuing involvement with Nycomed with respect to POSIDUR. Our estimate of the remaining term of our continuing
involvement was modified in the first quarter and the fourth quarter of 2009 as a result of updated development plans for POSIDUR in Europe.

We also received a $10.0 million upfront fee in connection with the license agreement signed with Endo in March 2005 relating to TRANSDUR-Sufentanil. The $10.0 million upfront fee is recognized as
collaborative research and development revenue ratably over the term of our continuing involvement with Endo with respect to TRANSDUR-Sufentanil. The term of the continuing involvement had been estimated based on the product development plan
pursuant to the agreement. Our estimate of the remaining term of our continuing involvement was modified in the fourth quarter of 2008 as a result of Endos termination notice that we received in February 2009.

We expect our collaborative research and development revenue to fluctuate in future periods pending our efforts to enter into potential new
collaborations and our existing third party collaborators commitment to and progress in the research and development programs. The collaborative research and development and other revenues associated with our major collaborators are as follows
(in thousands):

We amortize upfront fees on a straight-line basis over the period in which we have continuing involvement with
the third-party collaborator pursuant to the applicable agreement. Such period generally represents the research and development period set forth in the work plan under each collaboration agreement between us and our third-party collaborator.

Milestone payments under collaborative arrangements are recognized as revenue upon achievement of the milestone events, which
represent the culmination of the earnings process related to that milestone. We recorded $850,000 of milestone revenue from our Pain Therapeutics collaboration related to the achievement of clinical and regulatory milestones in 2008 and $8.0 million
of milestone revenue from our Nycomed collaboration due to the achievement of a clinical development milestone for POSIDUR in 2007.

Product revenue

A portion of our revenues is derived from our product sales, which include our ALZET mini pump product line, our LACTEL biodegradable polymer
product line and certain excipients that are included in Remoxy. Net product revenues were $12.1 million, $8.8 million and $8.3 million in 2009, 2008 and 2007, respectively. The increase in product revenue in 2009 compared with 2008 was
primarily attributable to higher product revenue from the sale of certain excipients included in Remoxy to King. Product revenue in 2009 also included $3.0 million related to shipments to King that occurred in 2008 and the first quarter of 2009 but
that had been deferred until a long term supply agreement was signed such that final terms and conditions of the sales were established. This agreement was executed in the quarter ended September 30, 2009, and all of the deferred revenue was
recognized as revenue in that period. In addition, we experienced higher product revenue from our LACTEL polymer product line as a result of higher units sold, partially offset by lower revenue from our ALZET mini pump product line as a result of
lower units sold in 2009.

The increase in product revenue in 2008 compared with 2007 was primarily due to higher average
selling prices for our ALZET mini pump and LACTEL polymers in 2008 compared with 2007. Product revenues attributable to the shipments of certain excipients that are included REMOXY in 2008 aggregating $1.3 million in 2008 had been deferred until a
final supply agreement with King was signed in the third quarter of 2009.

Cost of
revenues.    Cost of revenues was $5.3 million, $3.4 million and $3.2 million in 2009, 2008 and 2007, respectively. Cost of revenues includes the cost of product revenue from our ALZET mini pump product line, our LACTEL
polymer products and certain excipients that are included in Remoxy. The increase in the cost of product revenue in 2009 compared with 2008 was primarily the result of recognizing $2.0 million of cost of certain excipients for Remoxy sold to King,
partially offset by lower units sold from our ALZET mini pump product line and improved manufacturing efficiency from our LACTEL polymer product line. Cost of product revenue and gross profit margin will fluctuate from period to period depending
upon the product mix in a particular period. The increase in the cost of product revenue in 2008 compared with 2007 was primarily the result of higher product revenue by our ALZET and LACTEL product lines in 2008. Cost of goods sold aggregating
$562,000 in 2008 had been deferred until the execution of a final supply agreement with King in the third quarter of 2009. Stock based compensation expense recognized related to cost of revenues was $433,000, $135,000 and $130,000 in 2009, 2008 and
2007, respectively.

As of December 31, 2009, 2008 and 2007, we had 22, 31 and 23 manufacturing employees, respectively.

Research and Development.    Research and development expenses are primarily comprised of
salaries, benefits, stock based compensation and other compensation cost associated with research and development personnel, overhead and facility costs, preclinical and non-clinical development costs, clinical trial and related clinical
manufacturing costs, contract services, and other outside costs. In addition, research and development expenses incurred by us and reimbursed by Nycomed are recorded as a reduction to research and development expenses. Research and development
expenses incurred by Nycomed and reimbursed by us are recorded as additional research and development expenses. Research and development expenses were $34.6 million, $39.4 million and $38.3 million in 2009, 2008 and 2007. The decrease in 2009 was
primarily attributable to lower development costs associated with ELADUR, Remoxy and other select ORADUR-based opioid drug candidates and our biologics programs, partially offset by higher development costs associated with POSIDUR and other research
programs compared to 2008 as more fully discussed below. In addition, we paid $2.25 million to EpiCept in the third quarter of 2008 under our amended agreement with EpiCept and recorded this amount as a research and development expense in 2008.
Stock-based compensation expense recognized related to research and development personnel was $7.2 million, $5.6 million and $4.3 million in 2009, 2008 and 2007, respectively.

The increase in 2008 was primarily attributable to higher development costs associated with ELADUR, Remoxy and other ORADUR-based opioid
drug candidates, and our biologics programs, partially offset by decreased clinical trial expenses for POSIDUR, decreased development costs associated with CHRONOGESIC, TRANSDUR-Sufentanil and other research programs as more fully discussed below.
In addition, we paid $2.25 million to EpiCept in the third quarter of 2008 under the amended agreement with EpiCept and recorded this amount as a research and development expense in 2008.

TRANSDUR-Sufentanil

Our research and development expenses for TRANSDUR-Sufentanil were $1.4 million in both 2009 and 2008. We incurred higher employee related
cost for this product candidate in 2009 than in 2008, offset by decreased external costs after Endo returned the program to us in 2009.

Our research and development expenses for TRANSDUR-Sufentanil decreased to $1.4 million in 2008 from $2.8 million in 2007. The decrease was primarily due to lower development support activities performed
in support of this drug candidate in 2008.

CHRONOGESIC® (sufentanil) Pain Therapy System

Our research and development expenses for CHRONOGESIC decreased to $36,000 in 2009 from $89,000 in 2008. The decrease was primarily due to minimal costs incurred for this program in 2009.

Our research and development expenses for CHRONOGESIC decreased to $89,000 in 2008 from $1.7 million in 2007. The decrease was primarily due
to lower employee related costs and external development expenses in 2008.

Memryte

Our research and development expenses for Memryte decreased to zero in both 2009 and 2008 from $1.3 million in 2007 as we did not undertake
any research and development activities for this product candidate in 2009 and 2008. The reported research and development expense in 2007 includes a one-time cash payment of $1.0 million which we made in January 2007 as part of the amendment of our
license agreement with Curaxis.

Other DURECT Research Programs

Our research and development expenses for all other activities increased to $9.8 million from $7.0 million in 2008. The increase was
primarily due to higher employee related costs and increased formulation and clinical development activities for these programs.

Our research and development expenses for all other activities decreased to $7.0 million in 2008 from $8.9 million in 2007. The decrease was primarily due to lower employee related costs, partially offset by increased formulation and
clinical development activities for these programs.

As of December 31, 2009, 2008 and 2007, we had 77, 104 and 117
research and development employees respectively. We expect research and development expenses to increase in the near future as we continue product development efforts for our internal and partnered product candidates.

We cannot reasonably estimate the timing and costs of our research and development programs due to the risks and uncertainties associated
with developing pharmaceutical systems as outlined in the Risk Factors section of this report. The duration of development of our research and development programs may span as many as ten years or more, and estimation of completion dates
or costs to complete would be highly speculative and subjective due to the numerous risks and uncertainties associated with developing pharmaceutical products, including significant and changing government regulation, the uncertainties of future
preclinical and clinical study results, the uncertainties with our collaborators commitment to and progress in the programs and the uncertainties associated with process development and manufacturing as well as sales and marketing. In
addition, with respect to our development programs subject to third-party collaborations, the timing and expenditures to complete the programs are subject to the control of our collaborators. Therefore, we cannot reasonably estimate the timing and
estimated costs of the efforts necessary to complete the research and development programs. For additional information regarding these risks and uncertainties, see Risk Factors above.

Selling, General and Administrative.    Selling, general and
administrative expenses are primarily comprised of salaries, benefits and stock-based compensation associated with finance, legal, business development, sales and marketing and other administrative personnel, overhead and facility costs, and other
general and administrative costs. Selling, general and administrative expenses were $15.0 million in 2009 compared with $15.5 million in 2008. The decrease in selling, general and administrative expenses was primarily attributable to lower employee,
patent and consulting expenses incurred in 2009 compared with 2008. Stock-based compensation expense recognized related to selling, general and administrative personnel was $3.8 million, $2.8 million and $2.3 million in 2009, 2008 and 2007,
respectively.

Selling, general and administrative expenses were $15.5 million in 2008 compared with $13.6 million in 2007.
The increase in selling, general and administrative expenses was primarily attributable to higher employee related costs as well as increased patent related expenses in 2008 compared with 2007.

As of December 31, 2009, 2008 and 2007, we had 28, 38 and 36 selling, general and administrative personnel, respectively. We expect
selling, general and administrative expenses to remain comparable in the near future to support our business activities.

Write down of deferred royalties and commercial rights.    Write down of deferred royalties and commercial rights was zero, $13.5 million and zero in 2009, 2008 and 2007, respectively. In 2000, we recorded the
fair value of common stock and a warrant that we issued to ALZA Corporation in connection with an amended agreement related to CHRONOGESIC. The amounts were recorded in stockholders equity as additional paid-in capital and as a contra-equity
account referred to as deferred royalties and commercial rights. At the end of 2008, we made the strategic decision that other research and development programs would take priority over CHRONOGESIC and recorded a $13.5 million non-cash write down of
deferred royalties and commercial rights given the fact that there are no plans in the foreseeable future to actively attempt to develop CHRONOGESIC.

Other Income (Expense).    Interest and other income was $420,000, $1.5 million and $3.5 million in 2009, 2008 and 2007, respectively. The decreases in interest income were
primarily the result of lower yields on our investments as well as lower average cash and investment balances in 2009 and 2008 compared with 2007.

Interest expense was $36,000, $789,000 and $2.6 million in 2009, 2008 and 2007, respectively. The decrease in interest expense in 2009 and 2008 was primarily due to lower outstanding balances on our
convertible notes in 2009 and 2008 compared with 2007 due to the conversion of the remaining $23.6 million in aggregate principal amount of convertible notes in June 2008.

Debt conversion expense was zero, zero and $718,000 in 2009, 2008 and 2007, respectively. The debt conversion expense in 2007 was recorded
in connection with the conversion of $13.7 million in aggregate principal amount of the 6.25% convertible notes into 4.4 million shares of our common stock.

Income taxes.    As of December 31, 2009, we had net operating loss (NOL) carryforwards for federal income tax purposes of approximately $212.5 million, which expire in the
years 2018 through 2029, and federal research and development tax credits of approximately $4.2 million, which expire at various dates beginning in 2018 through 2029, if not utilized. As of December 31, 2009, we had NOL carryforwards for state
income tax purpose of approximately $131.8 million, which expire in the years 2012 through 2029, and state research and development tax credits of approximately $4.6 million, which do not expire. Utilization of the net operating losses may be
subject to a substantial annual limitation due to federal and state ownership change limitations. The annual limitation may result in the expiration of net operating losses and credits before utilization.

As of December 31, 2009 and 2008, we had net deferred tax assets of $107.3 million and $96.4 million, respectively. Deferred tax assets
reflect the net tax effects of net operating loss and credit carryforwards and the temporary differences between the carrying amounts of assets and liabilities for financial reporting and the

amounts used for income tax purposes. Realization of deferred tax assets is dependent upon future earnings, if any, the timing and amount of which are uncertain. Accordingly, the net deferred tax
assets have been fully offset by a valuation allowance.

Because realization of such tax benefits is uncertain, we provided a
100% valuation allowance as of December 31, 2009 and December 31, 2008. Utilization of the NOL and R&D credits carryforwards may be subject to a substantial annual limitation due to ownership change limitations that have occurred
previously or that could occur in the future provided by Sections 382 and 383 of the Internal Revenue Code of 1986, as well as similar state and foreign provisions. These ownership changes may limit the amount of NOL and R&D credits
carryforwards that can be utilized annually to offset future taxable income and tax, respectively. In general, an ownership change, as defined by Section 382, results from transactions increasing the ownership of certain shareholders or public
groups in the stock of a corporation by more than 50 percentage points over a three-year period. Since our formation, we have raised capital through the issuance of capital stock on several occasions which, combined with the purchasing
shareholders subsequent disposition of those shares, may have resulted in a change of control, as defined by Section 382, or could result in a change of control in the future upon subsequent disposition. In addition, we issued $60.0
million of convertible notes in 2003 and subsequently all of these notes had been converted as of December 31, 2008 into our common stock. We also issued approximately 4.4 million shares of our common stock to Venrock in connection with an
equity financing in September 2009. These transactions may also have resulted in a change of control or could result in a change of control in the future upon the subsequent disposition of the shares.

We have not currently completed a study to assess whether a change in control has occurred or whether there have been multiple changes of
control since our formation due to the significant complexity and cost associated with such a study and the fact that there could be additional changes in the future. If we have experienced a change of control at any time since our formation,
utilization of our NOL or R&D credits carryforwards would be subject to an annual limitation under Sections 382 and 383 which is determined by first multiplying the value of our stock at the time of the ownership change by the
applicable long-term tax-exempt rate, and then could be subject to additional adjustments, as required. Any limitation may result in expiration of a portion of our NOL or R&D credits carryforwards before utilization. Further, until a study is
completed and any limitation known, no amounts are being presented as an uncertain tax position under ASC 740, Income Taxes. Interest and penalties related to uncertain tax positions will be reflected in income tax expense. Tax years 1998 to
2009 remain subject to future examination by the major tax jurisdictions in which we are subject to tax.

Liquidity and Capital Resources

We had cash, cash equivalents, and investments totaling $41.6 million and $52.7 million at December 31, 2009 and
2008, respectively. This includes $431,000 and $1.0 million of interest-bearing marketable securities classified as restricted investments on our balance sheet as of December 31, 2009 and 2008, respectively, which primarily serve as collateral
for letters of credit securing our leased facilities and Alabama State Industrial Development Bonds payments which were assumed by us as part of our acquisition of SBS (SBS Bonds). The letter of credit related to the SBS bonds expired in November
2009. The letter of credit related to the security deposit of the leased facilities will expire in December 2012.

The
decrease in cash, cash equivalents and investments from 2008 to 2009 was primarily the result of ongoing operating expenses, partially offset by approximately $9.9 million received from our equity financing in 2009 as well as other payments received
from our customers and third-party collaborators. The decrease in cash, cash equivalents and investments from 2007 to 2008 was primarily the result of ongoing operating expenses, partially offset by a $20.0 million milestone payment from Alpharma
and other payments received from our customers and third-party collaborators.

Working capital was $34.8 million, $43.4
million and $25.7 million at December 31, 2009, 2008 and 2007, respectively. The decrease in working capital from 2008 to 2009 was primarily attributable to cash used for operations in 2009, partially offset by the receipt of net proceeds
from our equity financing in 2009. The increase

##### Table of Contents

in working capital from 2007 to 2008 was primarily attributable to the exchange of the $23.6 million in aggregate principal amount of convertible notes at maturity in June 2008 into approximately
7.5 million shares of common stock, partially offset by cash used for operations in 2008.

We used $20.9 million, $9.4
million and $18.3 million of cash in operating activities in the years ended December 31, 2009, 2008 and 2007, respectively. The increase in cash used in operating activities in 2009 was primarily due to decreases in accounts receivable and
inventory balances in 2009 compared with 2008. The decrease in cash used in operating activities in 2008 was primarily due to a $20.0 million milestone payment received from Alpharma in 2008 and increases in accounts receivable and inventory
balances in 2008 compared with 2007.

We used $10.4 million of cash from investing activities in the year ended
December 31, 2009 but generated $289,000 and $13.1 million of cash from investing activities in the years ended December 31, 2008 and 2007, respectively. The increase in cash used in investing activities in 2009 was primarily due to higher
net purchases of investments, offset by reduced purchases of property and equipment compared with 2008. The decrease in cash proceeds from investing activities in 2008 was primarily due to lower net proceeds received from maturing investments,
offset by reduced purchases of property and equipment compared with 2007.

We generated $10.1 million, $1.0 million and $1.3
million of cash from financing activities in the years ended December 31, 2009, 2008 and 2007, respectively. The increase in cash provided by financing activities in 2009 was primarily due to approximately $9.9 million of cash received from an
equity financing, partially offset by lower proceeds from exercises of stock options and purchases of our employee stock purchase plan in 2009. The decrease in cash provided by financing activities in 2008 was primarily due to lower proceeds from
exercises of stock options and a higher principal payment on the SBS bonds compared with 2007.

In November 2008, we filed a
new shelf registration statement on Form S-3 with the SEC, which upon being declared effective in May 2009, allowed us to offer up to $75 million of securities from time to time in one or more public offerings of our common stock.

On September 10, 2009, we entered into a privately negotiated transaction to sell 4,444,444 shares of our common stock to affiliates of
Venrock at a price of $2.25 per share, raising total gross proceeds of approximately $10.0 million. This transaction was completed on September 18, 2009. Total stock issuance costs related to this financing were approximately $126,000.

Cash used in our operating activities is heavily influenced by the timing and structure of new corporate collaborations.
While one feature of our business strategy is seeking new corporate collaborations, assuming no new collaborations and no milestone payments, we anticipate that cash used in operating activities will increase in the near future as we continue to
research, develop, and manufacture our pharmaceutical systems. In aggregate, we are required to make future payments pursuant to our existing contractual obligations as follows (in thousands):

We also anticipate incurring capital expenditures of approximately $500,000 over the next 12 months. The amount and timing of these capital expenditures will depend, among other things, on the success of
clinical trials for our product candidates and our collaborative research and development activities.

##### Table of Contents

We believe that our existing cash, cash equivalents and investments will be sufficient to
fund our planned operations, existing debt and contractual commitments and planned capital expenditures through at least the next 12 months. We may consume available resources more rapidly than currently anticipated, resulting in the need for
additional funding. Additionally, we do not expect to generate significant revenues from our pharmaceutical systems currently under development for at least the next twelve months, if at all. Depending on whether we enter into additional
collaborative agreements in the near term and the extent to which we earn milestone revenues, we may be required to raise additional capital through a variety of sources, including:



| |  |  | the public equity markets;
| | - |  | --------------------------



| |  |  | private equity financings;
| | - |  | --------------------------



| |  |  | collaborative arrangements; and/or
| | - |  | ----------------------------------



| |  |  | public or private debt.
| | - |  | -----------------------

There can be no assurance that we will enter into additional collaborative agreements in the near term, will earn milestone revenues or additional capital will be available on favorable terms, if at all.
If adequate funds are not available, we may be required to significantly reduce or refocus our operations or to obtain funds through arrangements that may require us to relinquish rights to certain of our products, technologies or potential markets,
either of which could have a material adverse effect on our business, financial condition and results of operations. To the extent that additional capital is raised through the sale of equity or convertible debt securities, the issuance of such
securities would result in ownership dilution to our existing stockholders.

Our cash and investments policy emphasizes
liquidity and preservation of principal over other portfolio considerations. We select investments that maximize interest income to the extent possible given these two constraints. We satisfy liquidity requirements by investing excess cash in
securities with different maturities to match projected cash needs and limit concentration of credit risk by diversifying our investments among a variety of high credit-quality issuers.

Off-Balance Sheet Arrangements

We have not utilized off-balance
sheet arrangements to fund our operations or otherwise manage our financial position.



|Item 7A. | Quantitative and Qualitative Disclosures About Market Risk.
|-------- | -----------------------------------------------------------

Interest Rate Sensitivity

Our exposure to market risk for changes in
interest rates relates primarily to our investment portfolio. Fixed rate securities and borrowings may have their fair market value adversely impacted due to fluctuations in interest rates, while floating rate securities may produce less income than
expected if interest rates fall and floating rate borrowings may lead to additional interest expense if interest rates increase. Due in part to these factors, our future investment income may fall short of expectations due to changes in interest
rates or we may suffer losses in principal if forced to sell securities which have declined in market value due to changes in interest rates.

Our primary investment objective is to preserve principal while at the same time maximizing yields without significantly increasing risk. Our portfolio includes money markets funds, commercial paper,
medium-term notes, corporate notes, government securities and corporate bonds. The diversity of our portfolio helps us to achieve our investment objectives. As of December 31, 2009, approximately 100% of our investment portfolio is composed of
investments with original maturities of one year or less and approximately 16% of our investment portfolio matures less than 90 days from the date of purchase.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Stockholders of DURECT Corporation

We have audited the accompanying balance sheets of DURECT Corporation as of December 31, 2009 and 2008, and the related statements of
operations, stockholders equity, and cash flows for each of the three years in the period ended December 31, 2009. Our audits also included the financial statement schedule listed in the Index at Item 15(a)(2). These financial
statements and schedule are the responsibility of the Companys management. Our responsibility is to express an opinion on these financial statements and schedule based on our audits.

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

In our opinion, the financial statements referred to above present fairly, in all material respects,
the financial position of DURECT Corporation at December 31, 2009 and 2008, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2009, in conformity with U.S. generally accepted

DURECT CORPORATION

NOTES TO FINANCIAL STATEMENTS

1.    Summary of Significant Accounting Policies

Nature of Operations

DURECT Corporation (the Company) was incorporated in the state of Delaware on February 6, 1998. The Company is a
pharmaceutical company developing therapies based on its proprietary drug formulations and delivery platform technologies. The Company has several products under development by itself and with third party collaborators. The Company also manufactures
and sells osmotic pumps used in laboratory research, and designs, develops and manufactures a wide range of standard and custom biodegradable polymers and excipients for pharmaceutical and medical device clients for use as raw materials in their
products. In addition, the Company conducts research and development of pharmaceutical products in collaboration with third party pharmaceutical and biotechnology companies.

Basis of Presentation and Use of Estimates

The Companys financial statements have been prepared in accordance with U.S. generally accepted accounting principles (U.S. GAAP). The preparation of financial statements in conformity with U.S.
GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue
and expenses during the reported period. Actual results could differ materially from those estimates. Specifically, management makes estimates when preparing the financial statements including those related to revenue recognition, accrued but
unbilled expenses for clinical trials and other services and stock-based compensation.

Cash, Cash Equivalents and
Investments

The Company considers all highly liquid investments with maturities of 90 days or less from the date of
purchase to be cash equivalents. Investments with original maturities of greater than 90 days from the date of purchase but less than one year from the balance sheet date are classified as short-term investments, while investments with maturities in
one year or beyond one year from the balance sheet date are classified as long-term investments. Management determines the appropriate classification of its cash equivalents and investment securities at the time of purchase and re-evaluates such
determination as of each balance sheet date. Management has classified the Companys cash equivalents and investments as available-for-sale securities in the accompanying financial statements. Available-for-sale securities are carried at fair
value, with unrealized gains and losses reported as a component of accumulated other comprehensive income (loss). Realized gains and losses are included in interest income. There were no material realized gains or losses in the periods presented.
The cost of securities sold is based on the specific identification method.

The Company invests its excess cash in debt
instruments of government agencies and corporations, and money market funds with high credit ratings. The Company has established guidelines regarding diversification of its investments and their maturities with the objectives of maintaining safety
and liquidity, while maximizing yield.

Concentrations of Credit Risk

Financial instruments that potentially subject the Company to credit risk consist principally of interest-bearing investments and trade
receivables. The Company maintains cash, cash equivalents and investments with various major financial institutions. The Company performs periodic evaluations of the relative credit standing of these financial institutions and limits the amount of
credit exposure with any one institution. In addition, the Company performs periodic evaluations of the relative credit quality of its investments.

NOTES TO FINANCIAL STATEMENTS(Continued)



Universities, pharmaceutical companies and hospitals account for a substantial portion
of the Companys trade receivables. The Company provides credit in the normal course of business to its customers and collateral for these receivables is generally not required. The risk associated with this concentration is limited due to the
large number of accounts and their geographic dispersion. The Company monitors the creditworthiness of its customers to which it grants credit terms in the normal course of business. The Company maintains reserves for estimated credit losses and, to
date, such losses have been within managements expectations. At December 31, 2009, King and one of the Companys feasibility partners accounted for 39% and 11% of the Companys net accounts receivable. At December 31, 2008,
Nycomed and Alpharma accounted for 31% and 29% of the Companys net accounts receivable.

Customer and Product Line
Concentrations

A portion of the Companys revenue is derived from its ALZET mini pump product line, LACTEL
biodegradable polymer product line and the sale of certain excipients for Remoxy. Revenue from the ALZET mini pump product line accounted for 26%, 25%, and 21% of total revenues in 2009, 2008 and 2007, respectively. The Companys revenue in
2009 from the sale of certain excipients for Remoxy and the LACTEL biodegradable polymer product line accounted for 12% and 11% of total revenues, respectively; revenue from these sources was less than 10% of total revenues in 2008 and 2007,
respectively.

In 2009, King accounted for 41% of the Companys total revenues. In 2008, Pain Therapeutics, Endo,
Alpharma, and Nycomed accounted for 24%, 15%, 13% and 11% of the Companys total revenues, respectively. In 2007, Nycomed, Pain Therapeutics and Endo accounted for 36%, 16% and 16% of the Companys total revenues, respectively.

Total revenue by geographic region for the years 2009, 2008 and 2007 is as follows (in thousands):

Property and Equipment

Property and equipment are stated at cost less accumulated depreciation, which is computed using the straight-line method over the estimated
useful lives of the assets, which range from three to five years. Leasehold improvements are amortized using the straight-line method over the estimated useful lives of the assets, or the terms of the related leases, whichever are shorter.

Acquired Intangible Assets and Goodwill

Acquired intangible assets consist of patents, developed technology, trademarks, assembled workforce and customer lists related to the
Companys acquisitions accounted for using the purchase method. Amortization of these purchased intangibles is calculated on a straight-line basis over the respective estimated useful lives of the assets ranging from four to seven years. The
Company assesses goodwill for impairment at least annually in accordance with ASC 350.

Impairment of Long-Lived Assets

In accordance with the provisions of ASC 360, the Company reviews long-lived assets, including property and equipment,
intangible assets, and other long-term assets, for impairment whenever events or changes in business circumstances indicate that the carrying amount of the assets may not be fully recoverable. Factors we consider important which could trigger an
impairment review include, but are not limited to, the following:



| |  |  | significant underperformance relative to expected historical or projected future operating results;
| | - |  | ---------------------------------------------------------------------------------------------------



| |  |  | significant changes in the manner of our use of the acquired assets or the strategy for our overall business;
| | - |  | -------------------------------------------------------------------------------------------------------------



| |  |  | significant negative industry or economic trends;
| | - |  | -------------------------------------------------



| |  |  | significant decline in our stock price for a sustained period; and
| | - |  | ------------------------------------------------------------------



| |  |  | a significant change in our market capitalization relative to net book value.
| | - |  | -----------------------------------------------------------------------------

Under ASC 360, an impairment loss would be recognized when estimated undiscounted future cash flows expected to result from the use of the
asset and its eventual disposition is less than its carrying amount. Impairment, if any, is calculated as the amount by which an assets carrying value exceeds its fair value, typically using discounted cash flows to determine fair value.
Through December 31, 2009, there have been no material impairment losses.

Stock-Based Compensation

The Company accounts for share-based payment under ASC 718, which requires the recognition of compensation expense,
using a fair-value based method, for costs related to all share-based payments, including stock options and stock issued under our employee stock purchase plan (ESPP). The Company estimates the fair value of share based payment awards on the date of
grant using an option-pricing model. See Note 8 for further information regarding stock-based compensation.

Revenue
Recognition

Revenue from the sale of products is recognized when there is persuasive evidence that an arrangement
exists, the product is shipped and title transfers to customers, provided no continuing obligation exists, the price is fixed or determinable and the collectability of the amounts owed is reasonably assured. The Company recognizes revenue from the
sale of its products and license and collaboration agreements pursuant to



76

DURECT CORPORATION

NOTES TO FINANCIAL STATEMENTS(Continued)



Accounting Standards Codification (ASC) 605, Revenue Recognition. Multiple element agreements entered into are evaluated under the provisions of ASC 605-25, Multiple Element
Arrangements. The Company evaluates whether there is stand-alone value for the delivered elements and objective and reliable evidence of fair value for the undelivered elements(s) to allocate revenue to each element in multiple element
agreements. When the delivered element does not have stand-alone value or there is insufficient evidence of fair value for the undelivered element(s), the Company recognizes the consideration for the combined unit of accounting in the same manner as
the revenue is recognized for the final deliverable, which is generally ratably over the longest period of involvement. Returns or credits related to the sale of products have not had a material impact on our revenues or net loss.

Upfront payments received upon execution of collaborative agreements are recorded as deferred revenue and recognized as collaborative
research and development revenue based on a straight-line basis over the period of the Companys continuing involvement with the third-party collaborator pursuant to the applicable agreement. Such period generally represents the research and
development period set forth in the work plan defined in the respective agreements between the Company and its third-party collaborators.

Research and development revenue related to services performed under the collaborative arrangements with the Companys third-party collaborators is recognized as the related research and development
services are performed. These research payments received under each respective agreement are not refundable and are generally based on reimbursement of qualified expenses, as defined in the agreements. Research and development expenses under the
collaborative research and development agreements generally approximate or exceed the revenue recognized under such agreements over the term of the respective agreements. Deferred revenue may result when the Company does not expend the required
level of effort during a specific period in comparison to funds received under the respective agreement. Pursuant to ASC 808-10, Collaborative Arrangements,for joint control and funding development activities, the Company will not recognize
revenue from the reimbursement of the research and development expenses but instead those reimbursements receivable from the joint venture party will be recorded as a reduction in research and development expense.

Milestone payments under collaborative arrangements are recognized as collaborative research and development revenue upon achievement of the
milestone events, which represent the culmination of the earnings process related to that milestone as defined in the agreement. Milestone payments are triggered either by the results of our research and development efforts or by events external to
us, such as regulatory approval to market a product or the achievement of specified sales levels by a third-party collaborator. As such, the milestones are substantially at risk at the inception of the collaboration agreement, and revenue is
only recognized upon the achievement of a milestone event if we have no future performance obligations related to that milestone payment.

The collaborative research and development and other revenues associated with the Companys major third-party collaborators are as follows (in thousands):

The Company amortizes up-front fees on a straight-line basis over the period in which the Company has
continuing involvement with the third-party collaborator pursuant to the applicable agreement. Such period generally represents the research and development period set forth in the work plan under each collaboration agreement between the Company and
its third-party collaborator.

Research and Development Expenses

Research and development expenses are primarily comprised of salaries and benefits associated with research and development personnel,
overhead and facility costs, preclinical and non-clinical development costs, clinical trial and related clinical manufacturing costs, contract services, and other outside costs. Research and development costs are expensed as incurred. Research and
development costs paid to third parties under sponsored research agreements are recognized as the related services are performed, generally ratably over the period of service. In addition, reimbursements by Nycomed for research and development
expenses incurred by the Company are recorded as a reduction to research and development expenses. Research and development expenses incurred by Nycomed and reimbursed by the Company are recorded as additional research and development expenses in
the period incurred.

Segment Reporting

The Company follows ASC 280, Segment Reporting, which establishes standards for reporting financial information about operating
segments in financial statements, as well as additional disclosures about products and services, geographic areas, and major customers. The Company operates in one operating segment, research and development of pharmaceutical systems.

Net Loss Per Share

Basic net loss per share is calculated by dividing the net loss by the weighted-average number of common shares outstanding. Diluted net loss per share is computed using the weighted-average number of
common shares outstanding and common stock equivalents (i.e., options and warrants to purchase common stock, convertible subordinated notes) outstanding during the year, if dilutive, using the treasury stock method for options and warrants and the
if-converted method for convertible subordinated notes.

The computation of diluted net loss per share for the fiscal year ended December 31, 2009 excludes the
impact of options to purchase 16.7 million shares of common stock, and a warrant to purchase 770 shares of common stock outstanding at December 31, 2009, as such impact would be antidilutive.

The computation of diluted net loss per share for the fiscal year ended December 31, 2008 excludes the impact of options to purchase
14.0 million shares of common stock, a warrant to purchase 770 shares of common stock outstanding at December 31, 2008 and 3.4 million shares of common stock associated with convertible subordinated notes prior to their conversion at
June 15, 2008, as such impact would be antidilutive.

The computation of diluted net loss per share for the fiscal year
ended December 31, 2007 excludes the impact of options to purchase 11.6 million shares of common stock, a warrant to purchase 770 shares of common stock and 10.2 million shares of common stock issuable upon conversion of the
subordinated notes outstanding at December 31, 2007, as such impact would be antidilutive.

Shipping and Handling

Costs related to shipping and handling are included in cost of revenues for all periods presented.

Operating Leases

The Company leases administrative, manufacturing and laboratory facilities under operating leases. Lease agreements may include rent holidays, rent escalation clauses and tenant improvement allowances.
The Company recognizes scheduled rent increases on a straight-line basis over the lease term beginning with the date the Company takes possession of the leased space. The Company records tenant improvement allowances as deferred rent liabilities on
the balance sheets and amortizes the deferred rent over the terms of the lease to rent expense on the statements of operations.

Recent Accounting Pronouncements

Effective July 1, 2009, the Company adopted The FASB
Accounting Standards Codification and the Hierarchy of Generally Accepted Accounting Principles(ASC 105). This standard establishes only two levels of U.S. generally accepted accounting principles (GAAP), authoritative and
nonauthoritative. The Codification became the source of authoritative, nongovernmental GAAP, except for rules and interpretive releases of the SEC, which are sources of authoritative GAAP for SEC registrants. All other non-grandfathered,
non-SEC accounting literature not included in the Codification became nonauthoritative. The Company began using the

DURECT CORPORATION

NOTES TO FINANCIAL STATEMENTS(Continued)



new guidelines and numbering system prescribed by the Codification when referring to GAAP in the third quarter of fiscal 2009. As the Codification was not intended to change or alter existing
GAAP, it did not have any impact on the Companys financial position or results of operations.

Effective April 1,
2009, the Company adopted three accounting standard updates which were intended to provide additional application guidance and enhanced disclosures regarding fair value measurements and impairments of securities. They also provide additional
guidelines for estimating fair value in accordance with fair value accounting. The first update, as codified in ASC 820-10-65, provides additional guidelines for estimating fair value in accordance with fair value accounting. The second accounting
update, as codified in ASC 320-10-65, changes accounting requirements for other-than-temporary-impairment (OTTI) for debt securities by replacing the current requirement that a holder have the positive intent and ability to hold an impaired security
to recovery in order to conclude an impairment was temporary with a requirement that an entity conclude it does not intend to sell an impaired security and it will not be required to sell the security before the recovery of its amortized cost basis.
The third accounting update, as codified in ASC 825-10-65, increases the frequency of fair value disclosures. These updates were effective for fiscal years and interim periods ended after June 15, 2009. The adoption of these accounting updates
did not have any impact on the Companys financial statements.

Effective January 1, 2009, the Company adopted a new
accounting standard update, as codified in ASC 820-10, that delayed the effective date of fair value measurements accounting for all non-financial assets and non-financial liabilities, except for items that are recognized or disclosed at fair value
in the financial statements on a recurring basis (at least annually), until the beginning of the first quarter of fiscal 2009. These include goodwill and other non-amortizable intangible assets. The adoption of this accounting update did not have
any impact on the Companys financial statements.

Effective January 1, 2009, the Company adopted a new accounting
standard update related to accounting for collaborative arrangements, as codified in ASC 808-10. In December 2007, the Emerging Issues Task Force of the FASB issued a consensus ASC 808-10. The scope of ASC 808-10 is limited to collaborative
arrangements where no separate legal entity exists and in which the parties are active participants and are exposed to significant risks and rewards that depend on the success of the activity. The Task Force concluded that revenue transactions with
third parties and associated costs incurred should be reported in the appropriate line item in each companys financial statements pursuant to the guidance in ASC 605-45. The Task Force also concluded that the equity method of accounting under
ASC 323, should not be applied to arrangements that are not conducted through a separate legal entity. The Task Force also concluded that the income statement classification of payments made between the parties in an arrangement should be based on a
consideration of the following factors: the nature and terms of the arrangement; the nature of the entities operations; and whether the parties payments are within the scope of existing GAAP. To the extent such costs are not within the
scope of other authoritative accounting literature, the income statement characterization for the payments should be based on an analogy to authoritative accounting literature or a reasonable, rational, and consistently applied accounting policy
election. The provisions of ASC 808-10 were effective for fiscal years beginning on or after December 15, 2008, and companies are required to apply the provisions through retrospective application to all collaborative arrangements existing at
adoption as a change in accounting principle. The adoption of this accounting update did not have any impact on the Companys financial statements.

In September 2009, the FASB issued Update No. 2009-13, Multiple-Deliverable Revenue Arrangementsa consensus of the FASB Emerging Issues Task Force (ASU 2009-13). It updates
the existing multiple-element revenue arrangements guidance currently included under ASC 605-25, which originated primarily from the guidance in EITF Issue No. 00-21, Revenue Arrangements with Multiple Deliverables (EITF 00-21). The
revised guidance primarily provides two significant changes: (1) eliminates the need for objective and reliable evidence of the fair value for the undelivered element in order for a delivered item to be treated as a separate unit



81

NOTES TO FINANCIAL STATEMENTS(Continued)



of accounting, and (2) eliminates the residual method to allocate the arrangement consideration. In addition, the guidance also expands the disclosure requirements for revenue recognition.
ASU 2009-13 will be effective for the first annual reporting period beginning on or after June 15, 2010, with early adoption permitted provided that the revised guidance is retroactively applied to the beginning of the year of adoption. The
Company is currently assessing the future impact of this new accounting update to its financial statements.

In January 2010,
the FASB issued Update No. 2010-06, Improving Disclosures about Fair Value Measurements that amended the disclosure requirements for the fair value measurements for recurring and nonrecurring assets and liabilities. The guidance
provides that an entity shall disclose any significant transfers of assets and liabilities between those that are actively traded in markets (level 1) and those that are not actively traded but have observable inputs (level 2), and the reasons for
the transfers. This guidance is effective for interim or fiscal periods beginning after December 15, 2009, which will be the Companys first quarter of fiscal 2010. The guidance also provides that disclosures for assets and liabilities
with significant unobservable inputs (level 3) should separately disclose purchases, sales, issuances and settlements. This guidance is effective for the Companys fiscal year beginning January 1, 2010. The Company does not expect the
adoption of this guidance to have a significant impact on its financial statements.

2.    Strategic Agreements

Agreement with Alpharma Ireland Limited, an affiliate of Alpharma Inc. (Alpharma) (acquired by King)

Effective October 2008, the Company and Alpharma, entered into a development and license agreement granting Alpharma the exclusive
worldwide rights to develop and commercialize ELADUR, DURECTs investigational transdermal bupivacaine patch. As a result of the acquisition of Alpharma by King in December 2008, King has assumed all the rights and obligations of Alpharma under
the agreement.

Under the terms of the agreement, upon closing of the transaction, Alpharma paid the Company an upfront
license fee of $20.0 million, with possible additional payments of up to $93.0 million upon the achievement of predefined development and regulatory milestones spread over multiple clinical indications and geographical
territories as well as possible additional payments of up to $150.0 million in sales-based milestones. If ELADUR is commercialized, the Company would also receive royalties on product sales. Alpharma will control and fund further
development of the program. The term of the agreement will continue on a jurisdiction-by-jurisdiction basis until the later of fifteen (15) years from the date of first commercial sale of ELADUR or the expiration of patent coverage or data
exclusivity in such jurisdiction. During the term of the agreement, subject to specified conditions, neither party nor their affiliates may develop or commercialize a transdermal patch containing bupivacaine. Upon expiration of the term of the
agreement, the rights and licenses granted to Alpharma shall convert to fully paid-up, non-royalty bearing, perpetual rights and licenses. The agreement provides each party with specified termination rights, including the right of Alpharma to
terminate at any time without cause and each party to terminate the agreement upon material breach of the agreement by the other party. The agreement also contains terms and conditions customary for this type of arrangement, including
representations, warranties and indemnities.

The Company recognized $3.4 million in 2009 and $752,000 in 2008 as
collaborative research and development revenue from the amortization of the $20.0 million upfront fee received, and $2.6 million in 2009 and $2.7 million in 2008 as collaborative research and development revenue from research expenses that are
qualified as reimbursement by Alpharma. The Companys estimate of the remaining term of our continuing involvement was modified in the second quarter of 2009 as a result of an updated development plan provided by King for ELADUR. Total
collaborative research and development revenue recognized under this arrangement was $6.0 million and $3.4 million for the years ended December 31, 2009 and 2008, respectively. The

cumulative aggregate payments received by the Company as of December 31, 2009 were $24.9 million under this agreement.

In November 2006, the Company entered into a development and license agreement with Nycomed, and this agreement was amended in February 2010. Under the terms of the agreement, the Company licensed to
Nycomed the exclusive commercialization rights to POSIDUR for the European Union (E.U.) and certain other countries. Nycomed paid an upfront license fee of $14.0 million in 2006 and a milestone payment of $8.0 million in 2007, with future potential
additional milestone payments of up to $181.0 million upon achievement of defined development, regulatory and sales milestones. Prior to the February 2010 amendment, the agreement provided for the Company and Nycomed to jointly directing and equally
funding with Nycomed a development program for POSIDUR intended to secure regulatory approval in both the U.S. and the E.U. After the amendment, DURECT now has final decision-making authority over clinical trials intended for the U.S. registration
of POSIDUR and Nycomed now has decision-making authority over clinical trials for the E.U. and other countries licensed to it. DURECT will have funding responsibility for all current and future clinical trials intended for U.S. registration of
POSIDUR and, commencing April 1, 2010, Nycomed will have sole funding responsibility for all clinical trials intended for E.U. registration of POSIDUR. The final decision making authority and financial responsibility for the remainder of the
development activities, such as the non-clinical and CMC activities, will be jointly managed and funded by DURECT and Nycomed. In addition, the Company will manufacture and supply the product to Nycomed for commercial sale in the territory licensed
to Nycomed. Nycomed will pay the Company blended royalties on sales in the defined territory of 15-40% depending on annual sales, as well as a manufacturing markup. The Company retains full commercial rights to POSIDUR in the U.S., Canada, Japan and
other countries. The agreement shall continue in effect until terminated. The agreement provides each party with specified termination rights, including the right of each party to terminate the agreement upon material breach of the agreement by the
other party. In addition, Nycomed shall have the right to terminate the agreement after expiration of patents covering POSIDUR in all major market countries in the E.U. and for adverse product events, and within specified periods after clinical
trials of POSIDUR.

In contrast to the Companys other collaborations, because the Company and Nycomed jointly control,
fund, and benefit from the development of POSIDUR, the Company does not recognize revenue from the reimbursement of qualified research expenses by Nycomed pursuant to ASC 808-10,Collaborative Arrangements. Rather, the Company records
research expense equal to its share of the joint expenses incurred under the product development plan. Research and development expenses for POSIDUR incurred by us but reimbursable by Nycomed under the terms of our agreement with Nycomed were $3.5
million, $3.6 million and $6.2 million in 2009, 2008 and 2007, respectively, which were accounted for as a reduction of research and development expenses. Research and development expenses for POSIDUR incurred by Nycomed but reimbursable by us under
the terms of our agreement with Nycomed were $4.7 million, $2.2 million and $1.2 million in 2009, 2008 and 2007, respectively, which were accounted for as additional research and development expenses. Both parties bear 50% of the agreed upon
expenses under the collaboration agreement for POSIDUR. The Company recognized $1.5 million, $3.1 million and $3.1 million in the years ended December 31, 2009, 2008 and 2007, respectively, as collaborative research and development revenue from
the amortization of the $14.0 million upfront fee received in 2006. The Companys estimate of the remaining term of its continuing involvement was modified in the first and fourth quarter of 2009 as a result of an updated development plan for
POSIDUR in Europe. In addition, the Company recognized an additional $8.0 million as collaborative research and development revenue, triggered by the achievement of a clinical development milestone under its Nycomed collaboration in 2007. The
cumulative aggregate payments received by the Company from Nycomed as of December 31, 2009 were $34.8 million under this agreement. In addition, the cumulative aggregate payments paid by the Company to Nycomed were $6.8 million as of
December 31, 2009.

Agreement with Endo Pharmaceuticals

On March 10, 2005, the Company entered into a license agreement with Endo under which the Company granted to Endo the exclusive right to
develop, market and commercialize TRANSDUR-Sufentanil in the U.S. and Canada. The Company received an initial payment of $10.0 million in connection with the execution of the agreement. The license agreement was terminated by Endo effective
August 26, 2009.

The $10.0 million upfront fee is recognized as revenue ratably over the term of the Companys
obliged continuing involvement with Endo with respect to TRANSDUR-Sufentanil. The term of the continuing involvement had been estimated based on the product development plan pursuant to the agreement. The Companys estimate of the remaining
term of its continuing involvement was modified the fourth quarter of 2008 as a result of Endos termination notice received by the Company in February 2009.

The Company recognized $875,000, $3.0 million and $2.2 million, respectively as collaborative research and development revenue from the amortization of the $10.0 million upfront fee for the years ended
December 31, 2009, 2008 and 2007. Total collaborative research and development revenue recognized under this arrangement was $985,000, $3.9 million and $4.8 million for the years ended December 31, 2009, 2008 and 2007, respectively. The
cumulative aggregate payments received by the Company as of December 31, 2009 were $21.5 million under this agreement.

Agreement with Pain Therapeutics, Inc.

In December 2002, the Company entered into an exclusive
agreement with Pain Therapeutics, Inc. (Pain Therapeutics) to develop and commercialize on a worldwide basis Remoxy and other oral sustained release, abuse deterrent opioid products incorporating four specified opioid drugs, using the
ORADUR technology. The agreement also provides Pain Therapeutics with the exclusive right to commercialize products developed under the agreement on a worldwide basis. In connection with the execution of the agreement, Pain Therapeutics paid the
Company upfront fees of $900,000 in December 2002 and $100,000 in October 2003. In December 2005, the Company amended its agreement with Pain Therapeutics in order to specify its obligations with respect to the supply of key excipients for use in
the licensed products. Under the agreement, as amended, the Company is responsible for formulation development, supply of selected key excipients used in the manufacture of licensed products and other specified tasks. Under the agreement with Pain
Therapeutics, subject to and upon the achievement of predetermined development and regulatory milestones for the four drug candidates currently in development, the Company is entitled to receive milestone payments of up to $9.3 million in the
aggregate. As of December 31, 2009, the Company had received $1.7 million in cumulative milestone payments. In addition, if commercialized, the Company will receive royalties for Remoxy and other licensed products which do not contain an opioid
antagonist of between 6.0% to 11.5% of net sales of the product depending on sales volume. This agreement can be terminated by either party for material breach by the other party and by Pain Therapeutics without cause. Under the agreement, Pain
Therapeutics reimburses the Company for qualified expenses incurred by the Company in connection with the development program. The Company recognizes collaborative research and development revenue related to research and development activities for
Remoxy and other development programs based on reimbursement of qualified expenses as defined in the collaborative agreement and related amendment with Pain Therapeutics. Total collaborative research and development revenue recognized under the
agreements with Pain Therapeutics was $317,000, $6.4 million and $4.9 million in 2009, 2008 and 2007, respectively. The cumulative aggregate payments received by the Company as of December 31, 2009 were $31.2 million under this agreement.

In March 2009, King assumed the responsibility for further development of Remoxy from Pain Therapeutics. As a result of this
change, the Company will continue to perform Remoxy related activities in

accordance with the terms and conditions set forth in the license agreement between the Company and Pain Therapeutics, but with King substituted in lieu of Pain Therapeutics with respect to
interactions with the Company in the Companys performance of those activities including the obligation to pay the Company with respect to all Remoxy related costs incurred by the Company. Total collaborative research and development revenue
recognized for Remoxy-related work performed by the Company for King was $983,000 for the year ended December 31, 2009, compared to zero for the corresponding periods in 2008 and 2007. Prior to March 2009, the Company recognized collaborative
research and development revenue for Remoxy related work under the agreements with Pain Therapeutics. The cumulative aggregate payments received by the Company from King as of December 31, 2009 were $811,000 under this agreement.

Long Term Supply Agreement with King

During 2008, the Company began to manufacture commercial lots of certain key excipients that are included in Remoxy to meet the anticipated requirements for these components. In addition, during the
second, third and fourth quarters of 2008 and the first quarter of 2009, the Company made shipments of these materials to meet the production requirements of King, which has rights to commercialize Remoxy upon approval by the FDA. During these
periods, all product revenue and associated cost of goods sold was deferred pending the establishment of definitive final terms and conditions even though cash receipts and expenditures occurred during these periods.

In August 2009, the Company signed an exclusive long term excipient supply agreement with respect to REMOXY with King. This agreement
stipulates the terms and conditions under which the Company will supply to King, based on the Companys manufacturing cost plus a specified percentage mark-up, two key excipients used in the manufacture of REMOXY. In the third quarter of 2009,
the Company recognized $3.0 million of product revenue and $2.0 million of cost of goods sold related to its past shipments to King upon execution of the long term supply agreement at which point all criteria of revenue recognition were met.

The term of the agreement commenced on August 5, 2009 and will continue in effect until the earlier of the expiration of
all licenses granted under the development and license agreement between the Company and Pain Therapeutics or the termination or expiration of the 2005 development and license agreement between Pain Therapeutics and King, unless the agreement is
terminated earlier in accordance with its terms. The agreement provides each party with specified termination rights, which include, but are not limited to, the right of King to terminate the agreement in the event that governmental action requires
the withdrawal of REMOXY from all countries in the territory or results in the withdrawal of required manufacturing approvals, or upon a change of control of the Company, in which case termination will be effective one year after notice by King. The
Company may terminate the agreement if the Company is unable to procure suitable and sufficient quantities of certain raw materials required to produce the excipient ingredients. Each party may terminate the agreement upon material breach of the
agreement by, or the bankruptcy or insolvency of, the other party, in each case subject to a cure period. The agreement further specifies the rights and obligations of the Company and King with respect to plant allocation, adding additional
production capacity and sourcing of raw materials, as well as other terms and conditions customary for this type of agreement, including those regarding forecasting, purchasing, invoicing, representations, warranties and indemnities.

Agreement with Curaxis Pharmaceutical Corporation (formerly Voyager Pharmaceutical Corporation)

In July 2002, the Company entered into a development and commercialization agreement with Voyager Pharmaceutical Corporation (now Curaxis).

Company is responsible for preclinical development, product manufacture and other specified tasks. Under the amended agreement, subject to and upon the achievement of predetermined development
and regulatory milestones, the Company is entitled to receive milestone payments from Curaxis of up to $3.0 million in the aggregate. As of December 31, 2008, the Company has received $500,000 in milestone payments. If commercialized, the
Company will receive royalties based on product sales of between ten to fourteen percent (10-14%) of the net sales of Memryte. In addition, the Company is entitled to receive ten percent (10%) of any upfront, milestone and other fees received
by Curaxis in the event that Memryte is sublicensed to a third party. This agreement can be terminated by either party for material breach by the other party. Under the agreement, Curaxis reimbursed the Company for qualified expenses incurred by the
Company in connection with the development program for Memryte. The Company recognized collaborative research and development revenue related to research and development activities for Memryte based on reimbursement of qualified expenses as defined
in the agreement, until August 2006 when the Company determined that the collectability of amounts owed was not reasonably assured. Development of Memryte has been halted pending raising of additional funds by Curaxis.

As a part of the amendment in January 2007, for year ended December 31, 2007, the Company paid Curaxis $1.0 million in cash and forgave
approximately $725,000 which was owed to the Company for previously provided services. The collaborative research and development revenue was recognized under the agreement with Curaxis was zero in 2009, 2008 and 2007, respectively. The cumulative
aggregate payments received by the Company as of December 31, 2009 were $11.6 million under this agreement.

Agreement with EpiCept Corporation

In December 2006, the Company entered into a license agreement
with EpiCept which provided the Company with the exclusive, worldwide license to certain of EpiCepts intellectual property for a transdermal patch containing bupivacaine for the treatment of back pain. Pursuant to the agreement, the Company
paid EpiCept a $1.0 million upfront fee in 2006 and subject to the Companys achievement of specified milestones, agreed to pay EpiCept an additional $9.0 million in milestone payments as well as an undisclosed royalty on net sales of any
product covered by the license. The $1.0 million fee was recognized as research and development expense at the execution of the agreement since the rights purchased had not yet reached technological feasibility and such rights also had no future
alternative uses.

In September 2008, the Company and EpiCept entered into an amendment to the license agreement. Under the
amendment, among other changes, the scope of the license was broadened from the treatment of back pain to all uses covered by the EpiCept intellectual property including myofascial pain and muscle tension pain, and the license was converted to an
exclusive, worldwide, fully paid up, royalty-free, perpetual and irrevocable license. In consideration of this amendment, the Company made a one-time payment of $2.25 million to EpiCept in full satisfaction of all future payment obligations to
EpiCept under the license agreement. The Company recorded the payment of $2.25 million as a research and development expense in the third quarter of 2008 since the rights purchased had not yet reached technological feasibility and such rights also
had no future alternative uses.

Agreement with ALZA Corporation

In April 1998, the Company entered into a development and commercialization agreement with ALZA, which has been
subsequently amended and restated, most recently in October 2002. The agreement provides the Company with exclusive rights to develop, commercialize and manufacture products using ALZAs patented DUROS® technology in selected fields of use, and obligates the Company to pay ALZA a royalty on the net sales of the Companys DUROS-based products and a
percentage of upfront license fees, milestone payments, or any other payments or consideration received by the Company with respect to such DUROS-based products. In

connection with the execution of the agreement, the Company issued 5,600,000 shares of Series A-1 preferred stock to ALZA, which were subsequently converted into 5,600,000 shares of common stock
concurrent with the Companys initial public offering in 2000. The Company issued an additional 1,000,000 shares of its common stock and a warrant to purchase 1,000,000 shares of its common stock to ALZA in connection with an amendment of the
agreement in April 2000. The Company recorded the fair value of the common stock and the warrant in the amount of $13.5 million as additional paid-in capital and as a contra-equity account referred to as deferred royalties and commercial rights. The
warrant expired in September 2004. At the end of 2008, the Company made the strategic decision that other research and development programs would take priority over CHRONOGESIC and recorded a $13.5 million non-cash write down of deferred royalties
and commercial rights associated with CHRONOGESIC given the fact that there are no plans in the foreseeable future to actively attempt to develop CHRONOGESIC (See Note 9). This agreement can be terminated by either party for material breach by the
other party and by the Company without cause.

The intangible assets are being amortized on a
straight-line basis over estimated useful lives ranging from four to seven years.

In December 2007 and January 2008, the
Company entered into patent assignment agreements and acquired from a third party two portfolios of worldwide patents and patent applications relating to drug delivery technologies. The Company paid $125,000 to this third party upon execution of the
agreements. In connection with these agreements. The Company had $125,000 as intangible assets on its balance sheet as of December 31, 2009 and has been amortizing these patents over an estimated useful life of 7 years.

The net amount of intangible assets at December 31, 2009 was $108,000, which will be amortized as follows: $37,000 in 2010, $17,600 in
each of the years from 2011 to 2014, and $900 in 2015. Should any intangible assets become impaired, the Company will write them down to their estimated fair value.

Goodwill totaled $6.4 million at December 31, 2009. The Company evaluates goodwill for impairment at least annually. In 2009, 2008 and 2007 goodwill was evaluated and no indicators of impairment were
noted.

Should goodwill become impaired, the Company may be required to record an impairment charge. To date, the Company has not recorded any impairment charge to goodwill.

4.    Financial Instruments

The carrying amount of cash equivalents reported on the balance sheet approximates fair value. Short-term and long-term investments consist of marketable debt securities. The fair values of investments
are based upon quoted market prices.

ASC 820-10 defines fair value, establishes a framework for measuring fair value under
generally accepted accounting principles and enhances disclosures about fair value measurements. Fair value is defined under ASC 820-10 as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the
principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value under ASC 820-10 must maximize the use of observable
inputs and minimize the use of unobservable inputs. The standard describes a fair value hierarchy based on three levels of inputs, of which the first two are considered observable and the last unobservable, that may be used to measure fair value.
These levels of inputs are the following:



| |  |  | Level 1Quoted prices in active markets for identical assets or liabilities.
| | - |  | ----------------------------------------------------------------------------



| |  |  | Level 2Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities;
quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Level 3Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or
liabilities.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------

The Companys financial instruments are valued using quoted prices in active markets or
based upon other observable inputs. The following table sets forth the fair-value of the Companys financial assets that were measured on at fair value a recurring basis as of December 31, 2009 (in thousands):

other-than-temporary declines in market value. Impairment is based on an analysis of factors that may have adverse effects on the fair value of the investment. Factors considered in determining whether a loss is temporary include the Companys
intent to sell the security, the Companys ability to hold the security to recovery of its amortized cost basis and the Companys assessment of the credit quality of the security, including whether we expect to recover the amortized cost
of the security.

The aggregate intrinsic value in the table above represents the total pretax intrinsic value
(i.e., the difference between the Companys closing stock price on the last trading day of 2009 and the exercise price, multiplied by the number of in-the-money options) that would have been received by the option holders had all option holders
exercised their options on December 31, 2009. This amount changes based on the fair market value of the Companys common stock. The total intrinsic value of options exercised was $101,000, $455,000 and $890,000 for the years ended
December 31, 2009, 2008 and 2007, respectively.

The weighted-average grant-date fair value of all options granted with
exercise price equal to fair market value was $1.95 in 2009, $4.02 in 2008 and $3.35 in 2007. There were no options granted with exercise prices lower than fair market value in 2009, 2008 and 2007.

Expenses for non-employee stock options are recorded over the vesting period of the options, with the amount determined by the Black-Scholes
option valuation method and remeasured over the vesting term.

As of December 31, 2009, the Company had four stock-based
employee compensation plans, which are described above. The employee stock-based compensation cost that has been included in the statements of operations was $11.4 million, $8.5 million and $6.7 million for the year ended December 31, 2009,
2008 and 2007. Because the Company had a net operating loss carryforward as of December 31, 2009, no excess tax benefits for the tax deductions related to stock-based compensation expense were recognized in our statement of operations.
Additionally, no incremental tax benefits were recognized from stock options exercised during 2009, which would have resulted in a reclassification to reduce net cash provided by operating activities with an offsetting increase in net cash provided
by financing activities.

Determining Fair Value

Valuation and Amortization Method.The Company estimates the fair value of stock options granted using the
Black-Scholes option valuation model. For options granted before January 1, 2006, the Company amortizes the fair value on an accelerated basis. For options granted on or after January 1, 2006, the Company amortizes the fair value on a
straight-line basis. All options are amortized over the requisite service periods of the awards, which are generally the vesting periods.

Expected Term.The expected term of options granted represents the period of time that the options are expected to be outstanding. In 2008 and 2009, the Company determined
the expected life using historical option experience. This develops the expected life by taking the weighted average of the actual life of options exercised and cancelled and assumes that outstanding options are exercised uniformly from the current
holding period through the end of the contractual life.

Prior to 2008, based on the limited historical exercise and
post-vesting termination of options granted under the Companys plans, the Company did not believe that it was able to rely on its historical employee exercise behavior to provide accurate data for estimating the Companys expected term
for use in determining the fair value of these options. Thus, the Company opted to use the simplified method for estimating its expected term and the average term was 6.25 years.

Expected Volatility.    The Company estimates the volatility of its common stock at the date of grant based on
the historical volatility of the Companys common stock.

Risk-Free Rate.The Company bases
the risk-free rate that it uses in the Black-Scholes option valuation model on the implied yield in effect at the time of option grant on U.S. Treasury zero-coupon issues with equivalent remaining terms.

Dividends.The Company has never paid any cash dividends on its common stock and the Company does not
anticipate paying any cash dividends in the foreseeable future. Consequently, the Company uses an expected dividend yield of zero in the Black-Scholes option valuation model.

The Company used the following assumptions to estimate the fair value of options granted and shares purchased under its employee stock plans
and stock purchase plan for the years ended December 31, 2009, 2008 and 2007:

The Company received $157,000, $518,000 and $849,000 in cash from option exercises under all
stock-based compensation plans for the years ended December 31, 2009, 2008 and 2007, respectively.

The Black Scholes
option-pricing model was developed for use in estimating the fair value of traded options that have no vesting restrictions and are fully transferable. The Black Scholes model requires the input of highly subjective assumptions including the
expected stock price volatility. The Companys stock based awards to employees have characteristics significantly different from those of traded options. Changes in the subjective input assumptions can materially affect the fair value estimate
of stock options and other awards.

Under the Black-Scholes option-pricing model, the Company historically estimated the
expected life of options using its best estimate of employee exercise behavior at the time. This estimate considered the vesting period for the employee stock options and a reasonable assumption about the post-vesting holding period. In anticipation
of adopting SFAS 123(R) on January 1, 2006, the Company updated this estimate to reflect more recent historical experience of employee stock option exercises and cancellations. The Company included the updated expected life of option assumption
for option grants made during the fourth quarter of 2005.

Stockholder Rights Plan

On July 6, 2001, the Board of Directors adopted a Stockholder Rights Plan. The rights issued pursuant to the plan expire on July 6,
2011 and are exercisable ten days after a person or group either (a) announces the acquisition of 17.5% or more of the Companys outstanding common stock or (b) commences a tender offer, which would result in ownership by the person
or group of 17.5% or more of the Companys outstanding common stock. Upon exercise, all rights holders except the potential acquiror will be entitled to acquire the Companys common stock at a discount. Under certain circumstances, the
Companys Board of Directors may also exchange the rights (other than those owned by the acquiror or its affiliates) for the Companys common stock at an exchange ratio of one share of common stock per right. The Company is entitled to
redeem the rights at any time on or before the tenth day following acquisition by a person or group of 17.5% or more of the Companys common stock.

9.    Write down of deferred royalties and commercial rights

In December 2008, the Company recorded a $13.5 million write down of the carrying value of deferred royalties and commercial rights associated with CHRONOGESIC. In 2000, the Company recorded the fair value of common stock and a warrant
issued to ALZA Corporation in connection with an amended agreement related to CHRONOGESIC as additional paid-in capital and a contra-equity account referred to as deferred royalties and commercial rights. At the end of 2008, the Company made the
strategic decision that other research and development programs would take priority over CHRONOGESIC and recorded this write down given the fact that the Company had no plans in the foreseeable future to actively attempt to develop CHRONOGESIC.

10.    Income Taxes

The Company accounts for income taxes using the liability method under ASC 740, Income Taxes. Under this method, deferred tax assets and liabilities are determined based on temporary differences
resulting from the different treatment of items for tax and financial reporting purposes. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences
are expected to reverse. Additionally, the Company must assess the likelihood that deferred tax assets will be recovered as deductions from future taxable income. The Company has provided a full valuation allowance on the Companys deferred tax
assets because the Company believes it is more likely than not that its deferred tax assets will not be realized. The Company evaluates the realizability of its deferred tax assets on a quarterly basis. Currently, there is no provision for income
taxes as the Company has incurred losses to date.

The reconciliation of income tax expenses (benefit) at the statutory
federal income tax rate of 34% to net income tax benefit included in the statement of operations for the years ended December 31, 2009, 2008 and 2007 is as follows (in thousands):

Deferred tax assets and liabilities reflect the net tax effects of net operating loss

|Total deferred tax assets                     |      |              | 107,243  |      |  |   | 96,423  |

Realization of deferred tax assets is dependent upon future earnings, if any, the timing and amount of which
are uncertain. Accordingly, the net deferred tax assets have been fully offset by a valuation allowance. The valuation allowance increased by $10.8 million, $10.4 million and $10.0 million during 2009, 2008 and 2007, respectively.

As of December 31, 2009, the Company had net operating loss carryforwards for federal income tax purposes of approximately $212.5
million, which expire in the years 2018 through 2029 and federal research and development tax credits of approximately $4.2 million which expire at various dates beginning in 2018 through 2029, if not utilized.

As of December 31, 2009, the Company had net operating loss carryforwards for state income tax purpose of approximately $131.8 million,
which expire in the years 2012 through 2029, if not utilized, and state research and development tax credits of approximately $4.6 million, which do not expire.

Utilization of the net operating losses may be subject to a substantial annual limitation due to federal and state ownership change limitations. The annual limitation may result in the expiration of net
operating losses before utilization.

Effective January 1, 2007, the Company adopted the provisions of ASC 740, Income
Taxes, which prescribes a recognition threshold and a measurement attribute for the financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. For those benefits to be recognized, a tax
position must be more-likely-than-not to be sustained upon examination by taxing authorities. There was not a material impact on the Companys financial position and results of operations as a result of the adoption of the provisions. At
December 31, 2008 and December 31, 2009, the Company had unrecognized tax benefits of approximately $3.3 million and $3.8 million, respectively (none of which, if recognized, would favorably affect the Companys effective tax rate).
The Company does not believe there will be any material changes in its unrecognized tax positions over the next twelve months.

Interest and penalty costs related to unrecognized tax benefits, if any, are classified as a component of
interest income and other income (expense), net in the accompanying Statements of Operations. The Company, however, did not recognize any interest and penalty expense related to unrecognized tax benefits for the years ended December 31, 2009,
2008 and 2007.

The Company files income tax returns in the U.S. federal jurisdiction and various state jurisdictions. The
Company is subject to U.S. federal and state income tax examination for calendar tax years ending 1998 through 2009.

11.    Reduction in Force

In March 2009, the Company reduced the size of its California
workforce by 41 employees or approximately 24% of its headcount. The goal of this action was to better align its cost structure with anticipated revenues and operating expenses, while not compromising the Companys key corporate objectives for
the year. The Company substantially completed this headcount reduction during the first quarter of 2009, and incurred approximately $443,000 in severance costs for the impacted employees, of which approximately $16,000 was paid in the first quarter
of 2009. All severance costs were paid during 2009.

Managements Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as
such term is defined in Exchange Act Rules 13a-15(f) and 15d-15(f). Under the supervision of our Chief Executive Officer and Chief Financial Officer and with the participation of our management, we conducted an evaluation of the
effectiveness of our internal control over financial reporting as of December 31, 2009 based on the framework in Internal ControlIntegrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).
Based on that evaluation, our management concluded that our internal control over financial reporting was effective as of December 31, 2009.

Our independent registered public accountants, Ernst & Young LLP, audited the financial statements included in this Annual Report on Form 10-K and have issued an audit report on our internal
control over financial reporting. The report on the audit of internal control over financial reporting appears below.

Changes in Internal Control Over Financial Reporting

There were no changes in our internal control over
financial reporting identified in connection with the evaluation required by paragraph (d) of Exchange Act Rules 13a-15 or 15d-15 that occurred during our last fiscal quarter that have materially affected or are reasonably likely to
materially affect, our internal control over financial reporting.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of DURECT Corporation

We have audited DURECT Corporations internal control over financial reporting as of December 31, 2009, based on criteria established in Internal ControlIntegrated Framework issued by the
Committee of Sponsoring Organizations of the Treadway Commission (the COSO criteria). DURECT Corporations management is responsible for maintaining effective internal control over financial reporting, and for its assessment of the
effectiveness of internal control over financial reporting included in the accompanying Managements Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the companys internal control over
financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our
audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk,
and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A companys internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial
statements for external purposes in accordance with generally accepted accounting principles. A companys internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that,
in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in
accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance
regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the companys assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of
any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, DURECT Corporation maintained, in all material respects, effective internal control over financial reporting as of
December 31, 2009, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public
Company Accounting Oversight Board (United States), the balance sheets of DURECT Corporation as of December 31, 2009 and 2008, the related statements of operations, stockholders equity, and cash flows for each of the three years in the
period ended December 31, 2009 of DURECT Corporation and the financial statement schedule listed in the Index at Item 15(a)(2) and our report dated March 4, 2010 expressed an unqualified opinion thereon.

|-------- | ------------------

Adjustment of Certain Items included in our Preliminary Unaudited Financial Statements and Earnings Release.    Subsequent to the issuance of our preliminary unaudited financial statements in conjunction with our
earnings announcement on February 24, 2010, the Company identified an adjustment of $427,000 relating to the stock-based compensation expense. The effects of this adjustment did not impact our previously reported net loss per share for the
three months ended December 31, 2009, but decreased our previously reported net loss per share for the year ended December 31, 2009 by $0.01 per share from $(0.37) to $(0.36). Our net loss per share was decreased from $(9,016,000) to
$(8,589,000) for the three months ended December 31, 2009 and from $(30,715,000) to $(30,288,000) for the year ended December 31, 2009.

As a result of the adjustment, cost of revenues, research and development expense and selling, general and administrative expense decreased respectively by $32,000, $279,000 and $116,000 for the three
months ended December 31, 2009 and for the year ended December 31, 2009. The effect on the Balance Sheet was to decrease both Accrued liabilities and Accumulated deficit in Stockholders equity by $427,000. The adjustment had no
effect on the previously reported Total assets and Total liabilities and stockholders equity.
