PART I  

Item 1. Business  

     Unless the context requires otherwise, the words “MannKind,” “we,” “company,” “us” and “our” refer to 
MannKind Corporation. Unless explicitly stated otherwise, AFRESA refers to the combination of AFRESA 
inhalation powder and the AFRESA inhaler.  

OVERVIEW  

     MannKind Corporation is a biopharmaceutical company focused on the discovery, development and 
commercialization of therapeutic products for diseases such as diabetes and cancer. Our lead product candidate, 
AFRESA, is an ultra rapid-acting insulin that has completed Phase 3 clinical trials evaluating its safety and efficacy 
in the treatment of diabetes. We believe that the performance characteristics, unique kinetics, convenience and ease 
of use of AFRESA has the potential to change the way diabetes is treated.  

     We believe that a distinguishing characteristic of AFRESA is that it produces a profile of insulin levels in the 
bloodstream that approximates the insulin profile normally seen in healthy individuals immediately following the 
beginning of a meal, but which is absent in patients with diabetes. Specifically, AFRESA is rapidly absorbed into the 
bloodstream following inhalation, reaching peak levels within 12 to 14 minutes. As a result of this rapid absorption, 
most of the glucose-lowering activity of AFRESA occurs within the first three hours of administration — which is 
generally when glucose becomes available from a meal — instead of the much longer duration of action observed 
when insulin is injected subcutaneously. We believe that the relatively short duration of action of AFRESA reduces 
the need for patients to snack between meals in order to manage ongoing blood glucose excursions. In our clinical 
trials, we have observed that patients using AFRESA have achieved significant reductions in post-meal glucose 
excursions and significant improvements in overall glucose control, as measured by decreases in glycosylated 
hemoglobin, or A1C, levels, without the weight gain typically associated with insulin therapy.  

     We have conducted an extensive clinical program, involving more than 40 different studies of AFRESA. 
Approximately 5,300 subjects participated in our clinical studies, of which more than 2,900 subjects were 
administered AFRESA. These studies were conducted in healthy volunteers, patients with type 1 and type 2 diabetes 
as well as diabetic patients with renal dysfunction, liver dysfunction, chronic obstructive pulmonary disease, asthma 
and upper respiratory tract infections. In addition, we have completed construction and achieved operational 
readiness of our state-of-the-art production facility in Danbury, Connecticut. We believe that our facility will satisfy 
the initial commercial demand for AFRESA, although the facility includes expansion space that will allow 
production capacity to be increased based on anticipated needs during the initial years of commercialization. We are 
preparing for pre-approval inspection of the facility by the United States Food and Drug Administration, or FDA.  

     We are in the final stages of preparing a new drug application, or NDA, for AFRESA to be submitted to the FDA 
shortly after the date of this annual report. The dossier is now drafted; we are currently performing the final 
hyperlinking and quality-checking activities, with the aim of providing the FDA with a high quality submission that 
can be efficiently reviewed. We will only be able to market AFRESA once, and if, the FDA approves our 
application.

     AFRESA utilizes our proprietary Technosphere formulation technology, which is based on a class of organic 
molecules that are designed to self-assemble into small particles onto which drug molecules can be loaded. 
Technosphere technology is not limited to insulin delivery. We believe it represents a versatile drug delivery 
platform that may allow pulmonary administration of certain drugs that currently require administration by injection. 
Beyond convenience, we believe the key advantage of drugs inhaled as Technosphere formulations is that they have 
been shown to be absorbed very rapidly into the arterial circulation, essentially mimicking intra-arterial 
administration.  

     We have prepared Technosphere formulations of a diverse assortment of drugs that represent a broad range of 
physicochemical characteristics, including anionic and cationic drugs, hydrophobic and hydrophilic drugs, and 
molecules ranging from 500 to 140,000 Daltons. In addition to insulin, we have generated clinical data from 
Technosphere formulations of parathyroid hormone, calcitonin and glucagon-like peptide-1, or GLP-1. Resource 
constraints currently limit our ability to continue the clinical development of any Technosphere-based products other 
than AFRESA.  

     In addition to our Technosphere platform, we are developing therapies for the treatment of different types of 
cancer. We are currently completing two clinical trials of our therapeutic cancer vaccines.  

     We were incorporated in the State of Delaware in 1991. Our principal executive offices are located at 28903

DIABETES  

     Diabetes is a major disease characterized by the body’s inability to properly regulate levels of blood glucose, or 
blood sugar. The cells of the body use glucose as fuel, which is consumed 24 hours a day. Between meals, when 
glucose is not being supplied from food, the liver releases glucose into the blood to sustain adequate levels. Insulin is 
a hormone produced by the pancreas that regulates the body’s blood glucose levels. Patients with diabetes develop 
abnormally high levels of glucose, a state known as hyperglycemia, either because they produce insufficient levels of 
insulin or because they fail to respond adequately to insulin produced by the body. Over time, poorly controlled 
levels of blood glucose can lead to major complications, including high blood pressure, blindness, amputations, 
kidney failure, heart attack, stroke and death.  

     According to the United States Centers for Disease Control, or CDC, approximately 20.8 million people in the 
United States, or 7% of the population, suffered from diabetes as of 2005. The CDC estimated that 14.6 million cases 
of diabetes were diagnosed and under treatment and that 1.5 million new cases would be diagnosed in 2005. More 
troubling is the fact that the incidence of diabetes is increasing. A study published by Diabetes Care in 2006 
projected that in 2050 there would be 48.3 million people with diagnosed diabetes in the United States. Diabetes 
extracts a heavy toll from those who suffer from it. The CDC reported that diabetes was the sixth leading cause of 
death listed on death certificates in 2002, but that diabetes was likely to be underreported as a cause of death. 
Overall, the CDC found that the risk of death among people with diabetes is about twice that of people without 
diabetes of similar age. The economic costs of diabetes are high as well. The American Diabetes Association 
estimated that, in 2007, the total cost of diabetes in the United States was $174 billion, an increase of 32% since 
2002. This amount includes $28 billion of direct costs for drug treatment for glucose control, of which approximately 
$6 billion were for insulin and delivery supplies and approximately $9 billion were for non-insulin oral medications.  

     There are two major forms of diabetes, type 1 and type 2. Type 1 diabetes is an autoimmune disease characterized 
by a complete lack of insulin secretion by the pancreas, so insulin must be supplied from outside the body in order to 
sustain life. In type 2 diabetes, the pancreas continues to produce insulin; however, insulin-dependent cells become 
resistant to the insulin effect. Over time, the pancreas becomes increasingly unable to secrete adequate amounts of 
insulin to support metabolism. According to the CDC, type 2 diabetes is the more prevalent form of the disease, 
affecting approximately 90% to 95% of people diagnosed with diabetes.  

Challenges of treating diabetes  

     Since patients with type 1 diabetes produce no insulin of their own, the primary treatment for type 1 diabetes is 
daily intensive insulin therapy. Such patients usually require a daily injection of long-acting, or basal, insulin along 
with an injection of rapid- or fast-acting  

4   

                                   
Table of Contents 

insulin at mealtimes.  

     When patients with type 2 diabetes are first diagnosed, the initial therapy is typically lifestyle intervention (diet 
and exercise) in order to try to normalize their blood glucose levels. As the disease progresses, treatment moves to 
various non-insulin oral medications. Often, the first drug introduced is metformin, which acts to reduce the glucose 
output of the liver. When this drug fails to reduce blood glucose levels, other drugs are added. Some of these 
additional medications act to increase the amount of insulin produced by the pancreas; others increase the sensitivity 
of muscle, fat and liver cells to the effects of insulin. Generally, these oral medications are limited in their ability to 
manage the disease effectively and tend to have significant side effects, such as weight gain and hypertension. 
Ultimately, many patients with type 2 diabetes will require insulin therapy in order to maintain appropriate levels of 
blood glucose.  

     Recently, the American Diabetes Association and the European Association for the Study of Diabetes published 
consensus treatment guidelines that advocated the initiation of insulin therapy after the failure of metformin. These 
groups emphasized that the early addition and intensification of insulin therapy was an important part of the 
treatment plan for patients with type 2 diabetes.  

     Although insulin therapy is accepted as an effective means to control glucose levels, the available insulin products 
have limitations, including:  

(cid:129)   the risk of severe hypoglycemia, which is abnormally low levels of blood glucose that result from excessive 

insulin administration. Hypoglycemia can result in loss of mental acuity, confusion, increased heart rate, hunger, 
sweating and faintness and, at very low glucose levels, loss of consciousness, seizures, coma and death;

(cid:129)   the likelihood of weight gain;

(cid:129)   inadequate post-meal glucose control;

(cid:129)   the need for complex titration of insulin doses in connection with meals; and

(cid:129)   the need for injections.

Because of these limitations, patients tend not to comply with the prescribed treatment regimens and are often under-
treated. Moreover, even when properly administered, subcutaneous injections of insulin do not replicate the natural 
time-action profile of insulin. In a person without diabetes, blood insulin levels rise within several minutes of the 
entry into the bloodstream of glucose from a meal. By contrast, injected insulin enters the bloodstream slowly, 
resulting in peak insulin levels in about 120 to 180 minutes for regular human insulin or 30-90 minutes for so-called 
“rapid-acting” insulin analogs. The consequence of these slower acting insulins is that patients do not have adequate 
levels of insulin present at the initiation of a meal and tend to be over-insulinized between meals. This lag in insulin 
delivery results in hyperglycemia early after meal onset, followed by a tendency for hypoglycemia to develop during 
the period between meals. Physicians who treat patients with diabetes are concerned about the risks of hypoglycemia 
and, as a result, tend to undertreat the chronic hyperglycemia that is associated with the disease. However, the 
resultant extensive hyperglycemia significantly contributes to many of the long-term cardiovascular and other serious 
complications of diabetes.  

The Mannkind Solution — Mimic Natural Insulin Release  

     In our clinical trials to date, we have consistently observed that AFRESA is rapidly absorbed into the bloodstream 
following inhalation, reaching peak levels within 12 to 14 minutes. In this manner, AFRESA produces a profile of 
insulin levels in the bloodstream that closely approximates the early insulin secretion normally seen in healthy 
individuals immediately following the beginning of a meal, but which is absent in patients with diabetes.  

     The pharmacokinetic profile distinguishes AFRESA from other insulin therapies. A 2004 review article in the 
British Journal of Diabetes and Vascular Diseases reviewed different studies of pulmonary insulin products in 
development and compared their glucose-lowering activity to that of injectable rapid-acting insulin analogs. The 
graph below from this article shows that most pulmonary insulin formulations have comparable time-action profiles 
to injectable rapid-acting insulin. The one exception was AFRESA, which was observed to have a much more rapid 
onset of action than the other insulin therapies reviewed.

Table of Contents 

     We believe the rapid action of AFRESA may be related to the unique aspects of both the carrier molecule as well 
as the way insulin is stabilized in our formulation. Our formulation technology is centered on a class of pH-sensitive 
organic molecules that self-assemble into small particles under mildly acidic conditions. We refer to these particles 
as Technosphere particles. Certain drugs, such as insulin, can be loaded onto these particles by combining a mildly 
acidic solution of the drug with a suspension of Technosphere material, which is then dried to a powder. This powder 
is then filled into plastic cartridges and packaged. To administer AFRESA, a patient loads a cartridge into our palm-
sized inhaler. By inhaling through the inhaler, air is pulled through the cartridge, which aerosolizes the powder and 
pulls the particles into the air current and out through the mouthpiece. The individual particles within this aerosol are 
small and have aerodynamic properties that enable them to fly deep into the lungs. When the particles contact the 
moist lung surface with its neutral pH, the Technosphere particles dissolve immediately, releasing the insulin 
molecules to diffuse across a thin layer of cells into the bloodstream. We believe that the insulin absorption step is a 
passive process that occurs without any active assistance or enhancement and without disruption of either cell 
membranes or the tight junctions between cells.  

     Significantly, when the Technosphere particles dissociate, we believe that the insulin that is released is in a form 
that can be readily used by the body. In most pharmaceutical dosage forms, regular human insulin exists as a 
hexamer, a complex of six associated insulin molecules. In order to exert a pharmacological effect, the hexamer must 
first dissociate into three dimers — complexes of two insulin molecules — which then further dissociate into 
individual insulin molecules, or monomers. Only monomeric insulin can attach to the insulin receptor and exert a 
physiological effect. Rapid-acting insulin analogs are designed to be fragile hexamers that dissociate more quickly, 
thereby reducing the time required to achieve an effect but this is still far slower than insulin that is released from a 
healthy pancreas. However, the insulin released from Technosphere particles is already largely in monomeric form. 
During the manufacture of AFRESA, we cause hexameric insulin to dissociate into monomeric insulin before being 
loaded onto Technosphere particles. When AFRESA particles dissolve in the deep lung, the insulin that is released 
diffuses across a thin layer of cells to reach the bloodstream. Little change is required before the insulin can start 
exerting its glucose-lowering effect in the body.  

More natural insulin profile translates into clinical benefits  

     In our clinical studies involving patients with diabetes, we observed that AFRESA produces the following clinical 
benefits:  

(cid:129)   Consistent decreases in A1C levels, comparable to current insulin therapies. We have evaluated A1C levels in a 

number of clinical studies involving patients with type 1 and type 2 diabetes. A consistent finding was that 
AFRESA produced decreases in A1C levels that were comparable to the decreases observed in the control arm 
of these studies, including studies that compared AFRESA to rapid-acting insulin analogs, to pre-mixed insulin 
analogs and to metformin in combination with a sulfonylurea.

Table of Contents 

(cid:129)   Superior post-meal glucose control. AFRESA has a shorter duration of action than other insulin therapies, so its 
glucose-lowering effect better meets a patient’s needs following a meal. Specifically, AFRESA produces lower 
blood glucose values than comparators in the first three hours following meal ingestion but does not remain 
active for an extended period of time, thereby reducing the risk of hypoglycemia between meals.

(cid:129)   Improved fasting glucose control. In clinical trials of both type 1 and type 2 diabetes, AFRESA has consistently 

provided better fasting blood glucose control than comparator insulin therapies.

(cid:129)   Less hypoglycemia due to better synchronization with glucose absorption from meals. In type 2 diabetes, 

AFRESA together with a basal insulin were compared to pre-mixed insulin analog. In clinical trials we observed 
that the overall risk of hypoglycemia was reduced and, in particular, there was a reduction in the risk of 
hypoglycemia in the late post-meal period, consistent with the novel action profile of AFRESA. In addition, 
there was a reduced risk of severe nocturnal hypoglycemia, a condition much feared by patients with diabetes. In 
clinical trials we observed similar results in patients with type 1 diabetes when comparing AFRESA to a rapid-
acting insulin analog, both in combination with basal insulin, although the differences were less pronounced.

(cid:129)   Little or no weight gain. In our clinical trials, patients receiving AFRESA experienced weight reduction or 

significantly less weight gain compared to other insulin therapies.

Favorable safety profile in clinical trials  

     To date, our clinical trials indicate that our AFRESA has a favorable safety profile. The most common adverse 
event reported with AFRESA therapy was a transient, mild and non-productive cough. The occurrence of mild cough 
is well recognized with inhaled medications. In our studies, the incidence of cough leading to the discontinuation of 
AFRESA was low.  

     After a two-year Phase 3 clinical trial of AFRESA, we determined that the use of AFRESA in patients with 
diabetes was non-inferior to usual diabetes care with respect to a decline in FEV1, a measure of lung function that 
assesses the volume of air that can be forcibly expired within one second. Similar results were obtained for other 
measures of lung function.  

     Our clinical trials for AFRESA have not demonstrated an increased risk of pulmonary cancer. In addition, we 
conducted comprehensive nonclinical studies of AFRESA and unloaded Technosphere particles, including a two-
year rat carcinogenicity study and a six-month transgenic mice study. These studies indicated that there was no 
increased risk of cancer, or any other clinical pathological effects.  

     We will establish a program of safety surveillance and adverse event reporting for the purpose of evaluating the 
ongoing safety data related to the use of AFRESA if it is approved by regulatory authorities.  

Convenient and easy to use  

     To facilitate the delivery of Technosphere-formulated drugs to the deep lung, we developed an inhaler that utilizes 
single-use, disposable, plastic cartridges containing drug-loaded powder. The AFRESA inhaler is light and easy to 
use, and fits in the palm of the patient’s hand, which we believe facilitates patient compliance. To administer a dose, 
the patient opens the device, inserts a cartridge of AFRESA inhalation powder into the inhaler, inserts the 
mouthpiece into the mouth and takes a deep breath, thereby drawing the aerosolized particles deep into the lungs. 
The inhaler incorporates an airflow regulator that is designed to ensure a sufficient airflow from use to use, even in 
patients with restricted airflow capacity. In addition, the inhaler is breath actuated, which means that the patient does 
not need to coordinate a breath with any manipulation of the device, such as priming or pumping. In our clinical trials 
of AFRESA, patients have reported a high level of satisfaction with the inhaler.  

     We believe the ease of use of the inhaler complements the time-action profile of the AFRESA powder to produce 
a highly convenient system. Because insulin is transferred to the bloodstream rapidly with our therapy, we believe 
that the optimal and most convenient time for patients to take a dose of AFRESA is right at the start of a meal. In 
contrast, with subcutaneous regular insulin it is recommended that the user try to time an injection 15 to 45 minutes 
before the expected mealtime, raising issues such as miscalculation of time or unanticipated change in meal 
availability, which could result in adverse events.

CANCER  

     Cancer is the unregulated proliferation of cells that have the capacity to spread to other sites in the body. A 
neoplasm is an uncontrolled growth of abnormal cells. A neoplasm is considered benign if it does not spread; if it 
invades other tissues, however, it is considered malignant. The term cancer refers to a malignant neoplasm.  

     The first goal of cancer treatment is to eradicate the cancer. Typically, this goal is pursued using treatment 
methods — surgery, radiation and chemotherapy — that can be highly toxic and may offer little clinical benefit. In 
the past decade or so, newer treatment methods have begun to emerge, including immunotherapy approaches that 
attempt to induce the immune system to kill tumor cells instead of tolerating them.  

Cancer immunotherapy  

     Our cancer immunotherapy program utilizes the body’s immune system to help eradicate tumor cells. The 
immune system is a network of cells and organs that defends the body against infection and abnormal cells, such as 
tumor cells. A key element of the immune system is its ability to distinguish between healthy cells and foreign or 
diseased cells that do not belong in the body. The immune system accomplishes this task by recognizing distinctive 
molecules called epitopes on the surface of each cell as either normal or abnormal, and responding to them 
appropriately. Any substance capable of being recognized by the immune system is known as an antigen. An antigen 
can be all or part of a pathogenic organism or it can be a by-product of diseased cells. Certain specialized cells of the 
immune system (antigen-presenting cells or APC) sample antigens found in the body and present the epitopes 
associated with foreign antigens to other cells of the immune system, known as T-cells, whose function is to destroy 
any cell that expresses the same epitope; this process is known as cell-mediated immunity. In this way, the immune 
system can launch a very specific response to infection or disease.  

     Our approach uses DNA- and peptide-based compounds that correspond to tumor-associated antigens that are 
expressed in a range of tumors. We select as target antigens molecules that either play a role in disease progression or 
that are very selectively expressed by tumor cells. A patient’s immune system is first “primed” by DNA-based 
compounds, or plasmids, that are injected directly into the patient’s lymph nodes. This is designed to sensitize the 
immune system to the tumor-associated antigens encoded by the plasmids. After a period of time, the patient’s lymph 
nodes are then injected with synthetic peptides that are designed to “boost” or greatly amplify the immune response 
to the target antigens. The immune response is maintained by repeated immunization cycles. This prime-boost 
regimen is designed to provoke a potent cell-mediated immune response that destroys cancer cells along with the 
underlying blood supply to tumors.  

     Our lead product candidate in this program, MKC1106-PP, is intended for the treatment of several solid-tumor 
cancers, including ovarian, colorectal, pancreatic, renal, breast, non-small cell lung and prostate carcinomas, 
glioblastoma and melanoma. In 2007, we commenced an open label Phase 1 clinical trial that is designed to evaluate 
the safety, tolerability and pharmacological response of MKC1106-PP in cancer patients with a variety of tumor 
types. This study is expected to be completed by the middle of 2009.  

     MKC1106-PP consists of three components: a plasmid that encodes pharmacological active elements from two 
tumor-associated antigens, known as PRAME and PSMA, and two synthetic peptides, one an analog of a PRAME 
epitope and one an analog of a PSMA epitope. In addition to melanoma, PRAME is expressed in carcinomas such as 
lung, breast, ovarian, renal, pancreatic and colorectal. PSMA was originally isolated from prostate carcinoma cells 
and later shown to be expressed in the blood vessels that supply several types of carcinoma, including breast, lung, 
ovarian, pancreatic, renal and colorectal carcinoma and melanoma.  

     In 2008, we also initiated an open-label Phase1/2 clinical trial of our second immunotherapy product candidate, 
MKC1106-MT. This trial is evaluating the tolerability and clinical responses to the therapy in patients with advanced 
melanoma. MKC1106-MT consists of a plasmid that encodes portions of two antigens known as Melan-A and 
tyrosinase, and two synthetic peptides, one an analog of a Melan-A epitope and one an analog of a tyrosinase epitope. 
Melan-A and tyrosinase are antigens commonly expressed by melanoma tumor cells.  

     The key features of our cancer immunotherapy program include the following:  

(cid:129)   It is a targeted therapeutic approach that aims to redirect patients’ immune response to the tumor targets 

expressed by their cancer. The patients with a highest likelihood to benefit from this treatment can be identified 
by histological analysis of their tumors.

(cid:129)   It involves an innovative and potent vaccination approach comprising direct intra-lymphatic administration of 

the immunizing components using a prime-boost sequence that is designed to achieve optimal response.

Table of Contents 

(cid:129)   The selected target antigens are molecules that play a key role in tumor progression and migration and that 

display increased expression, or selective expression, in tumor cells. Moreover, they are expressed in a range of 
cancers.

The immunizing components are “off the shelf” formulations of DNA and peptides containing excipients that are 
well recognized and generally regarded as safe. There is no need to harvest any material from patients’ tumors or 
cells in order to make our vaccine.  

OUR STRATEGY  

     Our objective is to develop products primarily in the major therapeutic areas of diabetes and cancer. Our strategy 
is to achieve this objective by doing the following:  

(cid:129)   Establish AFRESA as the preferred mealtime therapy within the broad population of people with diabetes. We 
believe the advantages in terms of safety, efficacy and convenience of AFRESA, as compared to subcutaneous 
insulin products, will enable us to capture a significant portion of the existing insulin-using diabetes market. Our 
target markets also include patients with type 2 diabetes who are currently using conventional therapies other 
than insulin, including:

(cid:129)   patients currently using diet and exercise therapy but who are having difficulty achieving proper blood 

glucose control and who otherwise would have started non-insulin oral medications; and

(cid:129)   patients currently using non-insulin medications.

(cid:129)   Expand our proprietary Technosphere formulation technology for the delivery of other peptide hormones. On 
the basis of some initial clinical studies, we believe that additional Technosphere formulations of peptide 
hormones have the potential to demonstrate clinical advantages over existing therapeutic options in diabetes, 
endocrine disorders and obesity.

(cid:129)   Commercialize our Technosphere portfolio with a partner who shares our commitment to improving the lives of 

patients with diabetes. We are evaluating potential collaboration opportunities with large pharmaceutical 
companies in the United States, Europe and Japan to provide marketing, sales and financial resources to 
commercialize and sell AFRESA. We have not licensed or transferred any of our rights to this product or to our 
platform technology.

(cid:129)   Develop novel approaches to treating cancer using our immunotherapy and drug discovery platforms. We are 
currently conducting a Phase 1 and a Phase 1/2 clinical trial of our investigational cancer immunotherapy 
product candidates. Our goal is to evaluate the safety and efficacy of this approach while also continuing to 
conduct research aimed at identifying novel drug therapies for cancer indications.

SALES AND MARKETING  

     Our efforts to date have primarily been directed at developing products for a number of different markets. We 
currently have no sales or distribution capabilities and have no experience as a company in marketing or selling 
pharmaceutical products. However, we have built a small marketing team and are actively engaged in the commercial 
activities that would normally be undertaken in preparation for launch of a pharmaceutical product.  

     In order to commercially market any of our products, we need either to develop an internal sales team, continue to 
expand our marketing infrastructure or collaborate with third parties who have greater sales and marketing 
capabilities and have access to potentially large markets. Although we believe that establishing our own sales and 
marketing organizations in North America would have substantial advantages, we recognize that this may not be 
practical for some of our products and that collaborating with companies with established sales and marketing 
capabilities in a particular market or markets may be a more effective alternative for some products. To date, we have 
retained worldwide commercialization rights for all of our products, including AFRESA. We believe that this will 
give us flexibility if we enter into collaborations to provide the necessary sales and marketing support.  

     We are evaluating potential collaboration opportunities to assist us in the commercialization of AFRESA in the 
United States and other major markets, and we may also create parallel in-house sales and marketing operations in 
certain key markets, particularly in the United States.  

MANUFACTURING AND SUPPLY  

     In November 2007, we entered into a long-term supply agreement with N. V. Organon, or Organon, (now owned 
by Schering-Plough Corporation) pursuant to which Organon will manufacture and supply specified quantities of 
recombinant human insulin to us. The  

9 

                                   
 
 
 
 
 
 
 
 
 
 
Table of Contents 

initial term of this supply agreement will end on December 31, 2012 and will be automatically extended for 
consecutive two-year periods unless (i) we fail to provide a forecast of our insulin requirements for the two-year 
extension period to Organon at least 24 months before any automatic extension or (ii) either party provides 23-
months’ advance written notice to the other party of its desire to terminate the agreement. We and Organon each have 
normal and customary termination rights, including (a) for material breach of the agreement by the other party, 
(b) due to the liquidation or bankruptcy of the other party or (c) upon 90-days advance written notice if the parties are 
unable to agree after mediation on the consequences of any changes to the product specifications required by any 
controlling regulatory authority. We may terminate the supply agreement upon 30-days advance written notice to 
Organon if certain regulatory authorities fail to approve or withdraw approval of AFRESA. If we terminate the 
supply agreement following failure to obtain or maintain regulatory approval of AFRESA or either party terminates 
the agreement following the parties’ inability to agree after any regulatory authority-mandated changes to product 
specifications that relate specifically to the use of insulin in AFRESA, we will be required to pay Organon a specified 
termination fee if Organon is unable to sell certain quantities of insulin to other parties. We believe that Organon has 
sufficient capacity to provide us with sufficient quantities of insulin to support our needs through the initial stages of 
commercialization. We must rely on our insulin supplier to maintain compliance with relevant regulatory 
requirements including current Good Manufacturing Practices, or cGMP.  

     We have a long-term supply agreement with Vaupell, Inc. for the manufacture and supply of our inhaler and the 
cartridges that are inserted into it. We have qualified a second manufacturer to supply us with commercial quantities 
of these components. We rely on our manufacturers to comply with relevant regulatory requirements, including 
compliance with Quality System Regulations, or QSRs. We believe our manufacturers have the capacity to meet our 
clinical trial and commercial requirements.  

     Currently, we purchase the raw material from which we produce Technosphere particles from a major chemical 
manufacturer with facilities in Europe and North America. We also have the capability of manufacturing this 
chemical ourselves in our Danbury, Connecticut facility, which is now treated as a back-up facility. Like us, our 
third-party manufacturers are subject to extensive governmental regulation.  

     We formulate and fill the AFRESA inhalation powder into plastic cartridges and blister package the cartridges in 
a manufacturing suite in our Danbury facility. With the recent completion of a major expansion project, we believe 
that our Danbury facility has adequate capacity to meet our anticipated needs for the initial years of 
commercialization. We are currently completing equipment installation and validation in order to ensure compliance 
with cGMP and to prepare for pre-approval inspection by the FDA. In addition, our quality management systems 
were certified to be in conformance with the ISO 13485 and ISO 9001 standards.  

INTELLECTUAL PROPERTY AND PROPRIETARY TECHNOLOGY  

     Our success will depend in large measure on our ability to obtain and enforce our intellectual property rights, 
effectively maintain our trade secrets and avoid infringing the proprietary rights of third parties. Our policy is to file 
patent applications on what we deem to be important technological developments that might relate to our product 
candidates or methods of using our product candidates and to seek intellectual property protection in the United 
States, Europe, Japan and selected other jurisdictions for all significant inventions. We have obtained, are seeking, 
and will continue to seek patent protection on the compositions of matter, methods and devices flowing from our 
research and development efforts. We have also in-licensed certain technology.  

     Our Technosphere drug delivery platform, including AFRESA, enjoys patent protection relating to the particles, 
their manufacture, and their use for pulmonary delivery of drugs. We have additional patent coverage relating to the 
treatment of diabetes using AFRESA. We have been granted patent coverage for our inhaler cartridges in the form in 
which our insulin product will be sold to the consumer. We have additional pending patent applications, and expect 
to file further applications, relating to the drug delivery platform, methods of manufacture, the AFRESA product and 
its use, and other Technosphere-based products, inhalers and inhaler cartridges. Overall, we own 35 issued patents 
and over 200 pending applications in the United States and select jurisdictions around the world related to our 
Technosphere platform. These include composition and method of treatment patents providing protection for 
AFRESA that will remain in force into 2020, and patents on our inhaler and inhaler cartridges that that will remain in 
force into 2023.  

     In addition, we own or have in-licensed intellectual property relating to several drug targets of interest in the 
treatment of cancer and other fields. Patents and patent applications in this area are drawn to drug screening methods, 
methods of treatment, and chemical structures of inhibitors of these targets. Our cancer immunotherapy program is 
built on proprietary methods for the selection, design and administration of epitopes, as well as the plasmids and 
peptides that are the active ingredients of our products. Overall we own 16 issued patents and over 180 pending 
applications in the United States and select jurisdictions around the world related to our immunotherapy program.

     The fields of pulmonary drug delivery and cancer therapies are crowded and a substantial number of patents have 
been issued in these fields. In addition, because patent positions can be highly uncertain and frequently involve 
complex legal and factual questions, the breadth of claims obtained in any application or the enforceability of issued 
patents cannot be confidently predicted. Further, there can be substantial delays in commercializing pharmaceutical 
products, which can partially consume the statutory period of exclusivity through patents.  

     In addition, the coverage claimed in a patent application can be significantly reduced before a patent is issued, 
either in the United States or abroad. Statutory differences in patentable subject matter may limit the protection we 
can obtain on some of our inventions outside of the United States. For example, methods of treating humans are not 
patentable in many countries outside of the United States. These and other issues may limit the patent protection we 
will be able to secure internationally. Consequently, we do not know whether any of our pending or future patent 
applications will result in the issuance of patents or, to the extent patents have been issued or will be issued, whether 
these patents will be subjected to further proceedings limiting their scope, will provide significant proprietary 
protection or competitive advantage, or will be circumvented or invalidated. Furthermore, patents already issued to 
us or our pending applications may become subject to disputes that could be resolved against us. In addition, patent 
applications in the United States filed before November 29, 2000 are currently maintained in secrecy until the patent 
issues, although in certain countries, including the United States, for applications filed on or after November 29, 
2000, applications are generally published 18 months after the application’s priority date. In any event, because 
publication of discoveries in scientific or patent literature often trails behind actual discoveries, we cannot be certain 
that we were the first inventor of the subject matter covered by our pending patent applications or that we were the 
first to file patent applications on such inventions.  

     Although we own a number of domestic and foreign patents and patent applications relating to our Technosphere-
based investigational products and our cancer products under development, we have identified certain third-party 
patents having claims relating to pulmonary insulin delivery that may trigger an allegation of infringement upon the 
commercial manufacture and sale of AFRESA. We have also identified third-party patents disclosing methods and 
compositions of matter related to DNA-based vaccines that also may trigger an allegation of infringement upon the 
commercial manufacture and sale of our cancer immunotherapy. We believe that we are not infringing any valid 
claims of any patent owned by a third party. However, if a court were to determine that our inhaled insulin product or 
cancer immunotherapies were infringing any of these patent rights, we would have to establish with the court that 
these patents were invalid in order to avoid legal liability for infringement of these patents. Proving patent invalidity 
can be difficult because issued patents are presumed valid. Therefore, in the event that we are unable to prevail in an 
infringement or invalidity action we will either have to acquire the third-party patents outright or seek a royalty-
bearing license. Royalty-bearing licenses effectively increase costs and therefore may materially affect product 
profitability. Furthermore, if the patent holder refuses to either assign or license us the infringed patents, it may be 
necessary to cease manufacturing the product entirely and/or design around the patents. In either event, our business 
would be harmed and our profitability could be materially adversely impacted. If third parties file patent applications, 
or are issued patents claiming technology also claimed by us in pending applications, we may be required to 
participate in interference proceedings in the United States Patent and Trademark Office, or USPTO, to determine 
priority of invention. We may be required to participate in interference proceedings involving our issued patents and 
pending applications.  

     We also rely on trade secrets and know-how, which are not protected by patents, to maintain our competitive 
position. We require our officers, employees, consultants and advisors to execute proprietary information and 
invention and assignment agreements upon commencement of their relationships with us. These agreements provide 
that all confidential information developed or made known to the individual during the course of our relationship 
must be kept confidential, except in specified circumstances. These agreements also provide that all inventions 
developed by the individual on behalf of us must be assigned to us and that the individual will cooperate with us in 
connection with securing patent protection on the invention if we wish to pursue such protection. There can be no 
assurance, however, that these agreements will provide meaningful protection for our inventions, trade secrets or 
other proprietary information in the event of unauthorized use or disclosure of such information.  

     We also execute confidentiality agreements with outside collaborators. However, disputes may arise as to the 
ownership of proprietary rights to the extent that outside collaborators apply technological information to our 
projects that are developed independently by them or others, or apply our technology to outside projects, and there 
can be no assurance that any such disputes would be resolved in our favor. In addition, any of these parties may 
breach the agreements and disclose our confidential information or our competitors might learn of the information in 
some other way. If any trade secret, know-how or other technology not protected by a patent were to be disclosed to 
or independently developed by a competitor, our business, results of operations and financial condition could be 
adversely affected.  

COMPETITION  

     The pharmaceutical and biotechnology industries are highly competitive and characterized by rapidly evolving 
technology and intense  

11   

                                   
Table of Contents 

research and development efforts. We expect to compete with companies, including the major international 
pharmaceutical companies, and other institutions that have substantially greater financial, research and development, 
marketing and sales capabilities and have substantially greater experience in undertaking preclinical and clinical 
testing of products, obtaining regulatory approvals and marketing and selling biopharmaceutical products. We will 
face competition based on, among other things, product efficacy and safety, the timing and scope of regulatory 
approvals, product ease of use and price.  

Diabetes treatments  

     We believe that AFRESA has important competitive advantages in the delivery of insulin when compared with 
currently known alternatives. However, new drugs or further developments in alternative drug delivery methods may 
provide greater therapeutic benefits, or comparable benefits at lower cost, than AFRESA. There can be no assurance 
that existing or new competitors will not introduce products or processes competitive with or superior to our product 
candidates.  

     We have set forth below more detailed information about certain of our competitors. The following is based on 
information currently available to us.  

Inhaled and oral insulin delivery systems  

     Currently, we are not aware of any other inhaled insulin products on the market or in development.  

     In January 2006, Exubera®, developed by Pfizer, Inc. in collaboration with Nektar Therapeutics, was approved for 
the treatment of adults with type 1 and type 2 diabetes. Exubera® was slow to gain market acceptance and, in 
October 2007, Pfizer announced that it was discontinuing the product. In September 2008, we announced a 
collaboration agreement with Pfizer pursuant to which certain patients with a continuing medical need for inhaled 
insulin were transitioned to AFRESA on a compassionate use basis. Pfizer subsequently withdrew the NDA for 
Exubera from the FDA.  

     In January 2008, Novo Nordisk A/S announced that it was halting development of its inhaled insulin product, 
having reached the conclusion that the product did not have adequate commercial potential. Notwithstanding the 
termination of this program, Novo Nordisk stated that it intended to increase research and development activities 
targeted at inhalation systems for long-acting formulations of insulin and GLP-1.  

     In March 2008, Eli Lilly and Company, or Eli Lilly, announced that it too was terminating the development of its 
AIR® inhaled insulin system. Lilly stated that this decision resulted from increasing uncertainties in the regulatory 
environment and after a thorough evaluation of the evolving commercial and clinical potential of its product 
compared to existing medical therapies.  

     There are several companies that are pursuing development of products involving the oral delivery of insulin. 
Biocon Limited is currently in Phase 2 clinical trials of IN-105, a tablet for the oral delivery of insulin. Emisphere 
Technologies, Inc. has also developed an oral formulation of insulin. A Phase 2 clinical trial of the Emisphere 
investigational product was completed in the fall of 2006. Other companies are evaluating alternative means of 
delivering insulin orally. Generex Biotechnology Corporation is currently conducting Phase 3 clinical trials in North 
America of its liquid formulation of insulin that is sprayed onto the buccal mucosa. This product, Oral-lyn™, is 
currently available for sale in certain countries, including Ecuador and India. Biodel Inc. is currently conducting 
Phase 1 clinical trials of an oral formulation of insulin (VIAtab™) designed to be administered sublingually. We are 
not aware that the timelines to commercialization for any of these investigational products have been made available 
publicly.  

Non-insulin medications  

     We expect that AFRESA will compete with currently available non-insulin medications for type 2 diabetes. These 
products include the following:  

(cid:129)   Sulfonylureas, also called oral hypoglycemic agents, prompt the pancreas to secrete insulin. This class of drugs 

is most effective in individuals whose pancreas still have some working pancreas cells.

(cid:129)   Meglitinides are taken with meals and reduce the elevation in blood glucose that generally follows eating. If 

these drugs are not taken with meals, blood glucose will drop dramatically and inappropriately.

(cid:129)   Biguanides lower blood glucose by improving the sensitivity of cells to insulin (i.e., by diminishing insulin 

resistance).

12 

                                   
 
 
 
 
 
Table of Contents 

(cid:129)   Thiazolidinedione improve the uptake of glucose by cells in the body.

(cid:129)   Alpha-glucosidase inhibitors lower the amount of glucose absorbed from the intestines, thereby reducing the rise 

in blood glucose that occurs after a meal.

(cid:129)   Inhibitors of dipeptidyl peptidase IV are a class of drugs that work by blocking the degradation of GLP-1, which 

is a naturally occurring incretin.

(cid:129)   Incretin mimetics work by several mechanisms including stimulating the pancreas to secrete insulin when blood 

glucose levels are high.

Injected insulin  

     In the subcutaneous insulin market, our competitors have made considerable efforts in promoting rapid acting 
injectable insulin formulations. Humalog®, which was developed by Eli Lilly, and NovoLog®, which was developed 
by Novo Nordisk A/S, are the two principal injectable insulin formulations with which we expect to compete.  

Cancer treatments  

     For many types of cancer, chemotherapy remains a significant component of the treatment regimen. Increasingly, 
however, drugs and antibodies that specifically target the abnormal mechanisms of proliferation, differentiation and 
invasion of malignant cells are being used to treat cancer. One such cancer therapy is Rituxan® (rituximab), an 
antibody marketed in the United States by Biogen IDEC and Genentech and by Roche in the rest of the world. 
Genentech, Inc. and Roche have also partnered to market two other successful antibodies: Avastin® 
(bevacizumab) and Herceptin® (trastuzumab). Erbitux® (cetuximab) is another antibody approved for use in 
metastatic colon cancer and squamous cell carcinoma of the head and neck. This antibody is marketed domestically 
by ImClone and Bristol-Myers Squibb and elsewhere by Merck KGaA.  

     The armamentarium of cancer treatments has been strengthened in recent years by several drugs that target 
specific molecular aberrations in tumor cells. One such drug is Gleevec®, developed and marketed by Novartis AG, 
which was initially approved for use in chronic myeloid leukemia. The drug has subsequently been approved for use 
in additional types of cancer. Velcade®, developed by Millenium Pharmaceuticals and Ortho Biotech, acts by 
inhibiting protein degradation, thereby inducing apoptosis. It was initially approved for use in multiple myeloma; its 
label now includes an indication for mantle cell lymphoma.  

     Our cancer products may face competition from the products described above as well as from other brands. In 
addition, our cancer immunotherapy products may face direct competition from one or more therapeutic cancer 
vaccines that may be approved in the coming years. Although there have been a number of notable failures recently 
among immunotherapy products in development, a few approaches continue to show potential:  

(cid:129)   Provenge® (Dendreon Corporation) is a vaccine composed of autologous APC that are loaded with an antigen 
(Prostate Acid Phosphatase) from prostate tumor cells then re-injected into patients. In May 2007, despite a 
positive vote from the Advisory Committee, Dendreon received a “Complete Response” letter from the FDA 
with respect to its application for the approval of Provenge® for the treatment of prostate cancer. Specifically, 
the FDA has requested that Dendreon provide additional survival data in order to support its claims that 
Provenge® is effective. Dendreon continues to generate survival data from their Phase 3 clinical trial and is 
planning to submit these data in 2009.

(cid:129)   MAGE-A3 is a tumor-specific antigen that is expressed in a large variety of cancers, including melanoma, non-

small cell lung cancer, head and neck cancer, bladder cancer, with no expression in normal cells. 
GlaxoSmithKline is evaluating a cancer vaccine that combines MAGE-A3, delivered as a purified recombinant 
protein, with certain immunostimulating compounds that are intended to increase the anti-tumor immune 
response. This investigational product is being evaluated in a Phase 3 clinical trials for the treatment of non-
small cell lung cancer and melanoma.

(cid:129)   CDX-110 is an immunotherapy being developed by Celldex, Inc. in collaboration with Pfizer. CDX-110 targets 

a mutated form of epidermal growth factor receptor that is present in multiple cancer types and is currently being 
evaluated for the treatment of glioblastoma multiforme in a Phase 2/3 clinical trial.

     The FDA and comparable regulatory agencies in state, local and foreign jurisdictions impose substantial 
requirements upon the clinical development, manufacture and marketing of medical devices and new drug products. 
These agencies, through regulations that implement the Federal Food, Drug, and Cosmetic Act, as amended, or 
FDCA, and other regulations, regulate research and development activities and the development, testing, 
manufacture, labeling, storage, shipping, approval, advertising, promotion, sale and distribution of such products. In 
addition, if our products are marketed abroad, they also are subject to export requirements and to regulation by 
foreign governments. The regulatory clearance process is generally lengthy, expensive and uncertain. Failure to 
comply with applicable FDA and other regulatory requirements can result in sanctions being imposed on us or the 
manufacturers of our products, including hold letters on clinical research, civil or criminal fines or other penalties, 
product recalls, or seizures, or total or partial suspension of production or injunctions, refusals to permit products to 
be imported into or exported out of the United States, refusals of the FDA to grant approval of drugs or to allow us to 
enter into government supply contracts, withdrawals of previously approved marketing applications and criminal 
prosecutions.  

     The steps typically required before an unapproved new drug product for use in humans may be marketed in the 
United States include:  

(cid:129)   Preclinical studies that include laboratory evaluation of product chemistry and formulation, as well as animal 
studies to assess the potential safety and efficacy of the product. Certain preclinical tests must be conducted in 
compliance with good laboratory practice regulations. Violations of these regulations can, in some cases, lead to 
invalidation of the studies, or requiring such studies to be repeated. In some cases, long-term preclinical studies 
are conducted while clinical studies are ongoing.

(cid:129)   Submission to the FDA of an investigational new drug application, or IND, which must become effective before 
human clinical trials may commence. The results of the preclinical studies are submitted to the FDA as part of 
the IND. Unless the FDA objects, the IND becomes effective 30 days following receipt by the FDA.

(cid:129)   Approval of clinical protocols by independent institutional review boards, or IRBs, at each of the participating 

clinical centers conducting a study. The IRBs consider, among other things, ethical factors, the potential risks to 
individuals participating in the trials and the potential liability of the institution. The IRB also approves the 
consent form signed by the trial participants.

(cid:129)   Adequate and well-controlled human clinical trials to establish the safety and efficacy of the product. Clinical 
trials involve the administration of the drug to healthy volunteers or to patients under the supervision of a 
qualified medical investigator according to an approved protocol. The clinical trials are conducted in accordance 
with protocols that detail the objectives of the study, the parameters to be used to monitor participant safety and 
efficacy or other criteria to be evaluated. Each protocol is submitted to the FDA as part of the IND. Human 
clinical trials are typically conducted in the following four sequential phases that may overlap or be combined:

(cid:129)   In Phase 1, the drug is initially introduced into a small number of individuals and tested for safety, dosage 
tolerance, absorption, metabolism, distribution and excretion. Phase 1 clinical trials are often conducted in 
healthy human volunteers and such cases do not provide evidence of efficacy. In the case of severe or life-
threatening diseases, the initial human testing is often conducted in patients rather than healthy volunteers. 
Because these patients already have the target disease, these studies may provide initial evidence of efficacy 
that would traditionally be obtained in Phase 2 clinical trials. Consequently, these types of trials are frequently 
referred to as Phase 1/2 clinical trials. The FDA receives reports on the progress of each phase of clinical 
testing and it may require the modification, suspension or termination of clinical trials if it concludes that an 
unwarranted risk is presented to patients or healthy volunteers.

(cid:129)   Phase 2 involves clinical trials in a limited patient population to further identify any 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.

(cid:129)   Phase 3 clinical trials are undertaken to further evaluate dosage, clinical efficacy and to further test for safety 

in an expanded patient population at geographically dispersed clinical study sites. Phase 3 clinical trials 
usually include a broader patient population so that safety and efficacy can be substantially established. Phase 
3 clinical trials cannot begin until Phase 2 evaluation demonstrates that a dosage range of the product may be 
effective and has an acceptable safety profile.

(cid:129)   Phase 4 clinical trials are performed if the FDA requires, or a company pursues, additional clinical trials after 

a product is approved. These clinical trials may be made a condition to be satisfied after a drug receives 
approval. The results of Phase 4 clinical trials can confirm the effectiveness of a product candidate and can 
provide important safety information to augment the FDA’s voluntary adverse drug reaction reporting system.

(cid:129)   Concurrent with clinical trials and preclinical studies, companies also must develop information about the 
chemistry and physical characteristics of the drug and finalize a process for manufacturing the product in 
accordance with drug cGMP requirements. The manufacturing process must be capable of consistently 
producing quality batches of the product and the manufacturer must develop methods for testing the quality, 
purity, and potency of the final products. Additionally, appropriate packaging must be selected and tested and 
chemistry stability studies must be conducted to demonstrate that the product does not undergo unacceptable 
deterioration over its shelf-life.

(cid:129)   Submission to the FDA of an NDA based on the clinical trials. The results of pharmaceutical development, 
preclinical studies, and clinical trials are submitted to the FDA in the form of an NDA for approval of the 
marketing and commercial shipment of the product. Under the Pediatric Research Equity Act of 2003, or PREA, 
NDAs are required to include an assessment, generally based on clinical study data, of the safety and efficacy of 
drugs for all relevant pediatric populations. The statute provides for waivers or deferrals in certain situations but 
we can make no assurances that such situations will apply to us or our product candidates.

     Medical products containing a combination of new drugs, biological products, or medical devices are regulated as 
“combination products” in the United States. A combination product generally is defined as a product comprised of 
components from two or more regulatory categories (e.g., drug/device, device/biologic, drug/biologic). Each 
component of a combination product is subject to the requirements established by the FDA for that type of 
component, whether a new drug, biologic, or device. In order to facilitate pre-market review of combination 
products, the FDA designates one of its centers to have primary jurisdiction for the pre-market review and regulation 
of the overall product. The determination whether a product is a combination product or two separate products is 
made by the FDA on a case-by-case basis. We have had discussions with the FDA about the status of AFRESA as a 
combination product and we have been told that the FDA considers our product a combination drug/device. There 
have been some indications from the FDA that the review of any marketing applications for AFRESA will involve 
reviews within the Division of Metabolism and Endocrinology Products and the Division of Pulmonary and Allergy 
Products, both within the Center for Drug Evaluation and Research, as well as review within the Center for Devices 
and Radiological Health, the Center within the FDA that reviews Medical Devices. Although the FDA has not made 
a final decision in this regard, we currently understand that the Division of Metabolic and Endocrine Products will be 
the lead group and obtain consulting reviews from the other two FDA groups if we submit an NDA.  

     The testing and approval process requires substantial time, effort and financial resources. We cannot be certain 
that any approval of our products will be granted on a timely basis, if at all. If any of our products are approved for 
marketing by the FDA, we will be subject to continuing regulation by the FDA, including record-keeping 
requirements, reporting of adverse experiences with the product, submitting other periodic reports, drug sampling 
and distribution requirements, notifying the FDA and gaining its approval of certain manufacturing or labeling 
changes, and complying with certain electronic records and signature requirements. Prior to and following approval, 
if granted, all manufacturing sites are subject to inspection by the FDA and other national regulatory bodies and must 
comply with cGMP, QSR and other requirements enforced by the FDA and other national regulatory bodies through 
their facilities inspection program. Foreign manufacturing establishments must comply with similar regulations. In 
addition, our drug-manufacturing facilities located in Danbury and the facilities of our insulin supplier, the supplier
(s) of our Technosphere material and the supplier(s) of our inhaler and cartridges are subject to federal registration 
and listing requirements and, if applicable, to state licensing requirements. Failure, including those of our suppliers, 
to obtain and maintain applicable federal registrations or state licenses, or to meet the inspection criteria of the FDA 
or the other national regulatory bodies, would disrupt our manufacturing processes and would harm our business. In 
complying with standards set forth in these regulations, manufacturers must continue to expend time, money and 
effort in the area of production and quality control to ensure full compliance. Currently, we believe we are operating 
under all of the necessary guidelines and permits.  

     We currently expect that our inhaler will be approved as part of the NDA for AFRESA. No assurances exist that 
we will not be required to obtain separate device clearances or approval for use of our inhaler with AFRESA. This 
may result in our being subject to medical device review user fees and to other device requirements to market our 
inhaler and may result in significant delays in commercialization. Even if the device component is approved as part 
of our NDA for AFRESA, numerous device regulatory requirements still apply to the device part of the drug-device 
combination. These include:  

(cid:129)   product labeling regulations;

(cid:129)   general prohibition against promoting products for unapproved or “off-label” uses;

(cid:129)   corrections and removals (e.g., recalls);

(cid:129)   establishment registration and device listing;

(cid:129)   general prohibitions against the manufacture and distribution of adulterated and misbranded devices; and

Table of Contents 

(cid:129)   the Medical Device Reporting regulation, which requires that manufacturers report to the FDA if their device 

may have caused or contributed to a death or serious injury or malfunctioned in a way that would likely cause or 
contribute to a death or serious injury if it were to recur.

     Further, the company we have contracted to manufacture our inhaler and cartridges will be subject to the QSR, 
which requires manufacturers to follow elaborate design, testing, control, documentation and other quality assurance 
procedures during the manufacturing process of medical devices, among other requirements.  

     Failure to adhere to regulatory requirements at any stage of development, including the preclinical and clinical 
testing process, the review process, or at any time afterward, including after approval, may result in various adverse 
consequences. These consequences include action by the FDA or another national regulatory body that has the effect 
of delaying approval or refusing to approve a product; suspending or withdrawing an approved product from the 
market; seizing or recalling a product; or imposing criminal penalties against the manufacturer. In addition, later 
discovery of previously unknown problems may result in restrictions on a product, its manufacturer, or the NDA 
holder, or market restrictions through labeling changes or product withdrawal. Also, new government requirements 
may be established or they may change at any time that could delay or prevent regulatory approval of our products 
under development. For example, in response to recent events regarding questions about the safety of certain 
approved prescription products, including the lack of adequate warnings, the FDA and Congress are currently 
considering new regulatory and legislative approaches to advertising, monitoring and assessing the safety of 
marketed drugs, including legislation providing the FDA with authority to mandate labeling changes for approved 
pharmaceutical products, particularly those related to safety. We also cannot be sure that the current Congressional 
and FDA initiatives pertaining to ensuring the safety of marketed drugs or other developments pertaining to the 
pharmaceutical industry will not adversely affect our operations. We cannot predict the likelihood, nature or extent of 
adverse governmental regulation that might arise from future legislative or administrative action, either in the United 
States or abroad.  

     In addition, the FDA imposes a number of complex regulations on entities that advertise and promote drugs, 
which include, among other requirements, standards for and regulations of direct-to-consumer advertising, off-label 
promotion, industry sponsored scientific and educational activities, and promotional activities involving the Internet. 
Such advertising and promotional activities are also being scrutinized by the FDA and Congress as a result of recent 
concerns that have been raised about the safety of marketed drugs. The FDA has very broad enforcement authority 
under the FDCA, and failure to comply with these regulations can result in penalties, including the issuance of a 
warning letter directing us to correct deviations from FDA standards, a requirement that future advertising and 
promotional materials be pre-cleared by the FDA, and state and federal civil and criminal investigations and 
prosecutions.  

     Products manufactured in the United States and marketed outside the United States are subject to certain FDA 
regulations, as well as regulation by the country in which the products are to be sold. We also would be subject to 
foreign regulatory requirements governing clinical trials and drug product sales if products are marketed abroad. 
Whether or not FDA approval has been obtained, approval of a product by the comparable regulatory authorities of 
foreign countries usually must be obtained prior to the marketing of the product in those countries. The approval 
process varies from jurisdiction to jurisdiction and the time required may be longer or shorter than that required for 
FDA approval.  

     Product development and approval within this regulatory framework take a number of years, involve the 
expenditure of substantial resources and are uncertain. Many drug products ultimately do not reach the market 
because they are not found to be safe or effective or cannot meet the FDA’s other regulatory requirements. In 
addition, there can be no assurance that the current regulatory framework will not change or that additional regulation 
will not arise at any stage of our product development that may affect approval, delay the submission or review of an 
application or require additional expenditures by us. There can be no assurance that we will be able to obtain 
necessary regulatory clearances or approvals on a timely basis, if at all, for any of our product candidates under 
development, and delays in receipt or failure to receive such clearances or approvals, the loss of previously received 
clearances or approvals, or failure to comply with existing or future regulatory requirements could have a material 
adverse effect on our business and results of operations.  

     Under European Union regulatory systems, marketing authorizations may be submitted either under a centralized 
or decentralized procedure. The centralized procedure provides for the grant of a single marketing authorization that 
is valid for all European Union member states. The decentralized procedure provides for mutual recognition of 
national approval decisions. Under this latter procedure, the holder of a national marketing authorization may submit 
an application to the remaining member states. Within 90 days of receiving the application and assessment report, 
each member state must decide whether to recognize approval. We plan to choose the appropriate route of European 
regulatory filing in an attempt to accomplish the most rapid regulatory approvals. However, the chosen regulatory 
strategy may not secure regulatory approvals or approvals of the chosen product indications. In addition, these 
approvals, if obtained, may take longer than anticipated.  

     We cannot provide assurance that any of our product candidates will prove to be safe or effective, will receive 
regulatory approvals, or will be successfully commercialized.

     In addition to the foregoing, we are subject to numerous federal, state and local laws relating to such matters as 
laboratory practices, the experimental use of animals, the use and disposal of hazardous or potentially hazardous 
substances, controlled drug substances, safe working conditions, manufacturing practices, environmental protection 
and fire hazard control. We may incur significant costs to comply with those laws and regulations now or in the 
future.  

Patent restoration and marketing exclusivity  

     The Drug Price Competition and Patent Term Restoration Act of 1984, known as the Hatch-Waxman 
Amendments to the Federal Food, Drug, and Cosmetic Act, permits the FDA to approve abbreviated NDAs, or 
ANDAs, for generic versions of innovator drugs and also provides certain patent restoration and market exclusivity 
protections to innovator drug manufacturers. The ANDA process permits competitor companies to obtain marketing 
approval for a new drug with the same active ingredient for the same uses, dosage form and strength as an innovator 
drug but does not require the conduct and submission of preclinical or clinical studies demonstrating safety and 
efficacy for that product. Instead of providing completely new safety and efficacy data, the ANDA applicant only 
needs to submit manufacturing information and clinical data demonstrating that the copy is bioequivalent to the 
innovator’s product in order to gain marketing approval from the FDA.  

     Another type of marketing application allowed by the Hatch-Waxman Amendments, a Section 505(b)(2) 
application, may be permitted where a company does not own or have a right to reference all the data required for 
approval. Section 505(b)(2) NDAs are often submitted for drug products that contain the same active ingredient as 
those in first approved drug products and where additional studies are required for approval, such as for changes in 
routes of administration or dosage forms.  

     Once an NDA is approved, the product covered thereby becomes a “listed drug” which can, in turn, be cited by 
potential competitors in support of approval of an ANDA or a 505(b)(2) application.  

     The Hatch-Waxman Amendments provide for a period of three years exclusivity following approval of a listed 
drug that contains previously approved active ingredients but is approved in a new dosage, dosage form, route of 
administration or combination, or for a new use, the approval of which was required to be supported by new clinical 
trials conducted by or for the sponsor. During this period of exclusivity, FDA cannot grant effective approval of an 
ANDA or a 505(b)(2) application based on that listed drug.  

     The Hatch-Waxman Amendments also provide a period of five years exclusivity following approval of a drug 
containing no previously approved active ingredients. During this period of exclusivity, ANDAs or 505(b)(2) 
applications based upon those drugs cannot be submitted unless the submission accompanies a challenge to a listed 
patent, in which case the submission may be made four years following the original product approval.  

     Additionally, in the event that the sponsor of the listed drug has informed FDA of patents covering its listed drug 
and FDA lists those patents in the Orange Book, applicants submitting an ANDA or a 505(b)(2) application 
referencing that drug are required to certify whether they intend to market their generic products prior to expiration 
of those patents. If an ANDA applicant certifies that it believes one or more listed patents is invalid or not infringed, 
it is required to provide notice of its filing to the NDA sponsor and the patent holder. If either party then initiates a 
suit for patent infringement against the ANDA sponsor within 45 days of receipt of the notice, FDA cannot grant 
effective approval of the ANDA until either 30 months has passed or there has been a court decision holding that the 
patent in question is invalid or not infringed. If the ANDA applicant certifies that it does not intend to market its 
generic product before some or all listed patents on the listed drug expire, then FDA cannot grant effective approval 
of the ANDA until those patents expire. The first ANDA applicant submitting substantially complete applications 
certifying that listed patents for a particular product are invalid or not infringed may qualify for a period of 180 days 
after a court decision of invalidity or non-infringement or after it begins marketing its product, whichever occurs 
first. During this 180 day period, subsequently submitted ANDAs cannot be granted effective approval.  

     The FDA Modernization Act of 1997 included a pediatric exclusivity provision that was extended by the Best 
Pharmaceuticals for Children Act of 2002. Pediatric exclusivity is designed to provide an incentive to manufacturers 
for conducting research about the safety and efficacy of their products in children. Pediatric exclusivity, if granted, 
provides an additional six months of market exclusivity in the United States for new or currently marketed drugs if 
certain pediatric studies requested by the FDA are completed by the applicant and the applicant has other existing 
patent or exclusivity protection for the drug. To obtain this additional six months of exclusivity, it would be 
necessary for us to first receive a written request from the FDA to conduct pediatric studies and then to conduct the 
requested studies according to a previously agreed timeframe and submit the report of the study. There can be no 
assurances that we would receive a written request from the FDA and if so that we would complete the studies in 
accordance with the requirements for this six-month exclusivity. The current pediatric exclusivity provision is 
scheduled to end on October 1, 2012, and there can be no assurances that it will be reauthorized.

Item 1A. Risk Factors  

     You should consider carefully the following information about the risks described below, together with the other 
information contained in this report before you decide to buy or maintain an investment in our common stock. We 
believe the risks described below are the risks that are material to us as of the date of this Annual Report. Additional 
risks and uncertainties that we are unaware of may also become important factors that affect us. If any of the 
following risks actually occur, our business, financial condition, results of operations and future growth prospects 
would likely be materially and adversely affected. In these circumstances, the market price of our common stock 
could decline, and you may lose all or part of the money you paid to buy our common stock.  

RISKS RELATED TO OUR BUSINESS  

We have a history of operating losses, we expect to continue to incur losses and we may never become profitable. 

     We are a development stage company with no commercial products. All of our product candidates are still being 
developed, and all but AFRESA are still in the early stages of development. Our product candidates will require 
significant additional development,  

20  

                                   
Table of Contents 

clinical trials, regulatory clearances and additional investment before they can be commercialized. We anticipate that 
AFRESA will not be commercially available for at least one year, if at all.  

     We have never been profitable and, as of December 31, 2008, we had an accumulated deficit of $1.4 billion. The 
accumulated deficit has resulted principally from costs incurred in our research and development programs, the 
write-off of goodwill and general operating expenses. We expect to make substantial expenditures and to incur 
increasing operating losses in the future in order to further develop and commercialize our product candidates, 
including costs and expenses to complete clinical trials, seek regulatory approvals and market our product candidates, 
including AFRESA. This accumulated deficit may increase significantly as we expand development and clinical trial 
efforts.  

     Our losses have had, and are expected to continue to have, an adverse impact on our working capital, total assets 
and stockholders’ equity. Our ability to achieve and sustain profitability depends upon obtaining regulatory approvals 
for and successfully commercializing AFRESA, either alone or with third parties. We do not currently have the 
required approvals to market any of our product candidates, and we may not receive them. We may not be profitable 
even if we succeed in commercializing any of our product candidates. As a result, we cannot be sure when we will 
become profitable, if at all.  

If we fail to raise additional capital, our financial condition and business would suffer.  

     It is costly to develop therapeutic product candidates and conduct clinical trials for these product candidates. 
Although we are currently focusing on AFRESA as our lead product candidate, we have begun to conduct clinical 
trials for additional product candidates. Although development of AFRESA has been completed, our existing capital 
resources will not be sufficient to support the expense of fully commercializing AFRESA or development of any of 
our other product candidates.  

     Based upon our current expectations, we believe that our existing capital resources, including the loan 
arrangement with an entity controlled by our principal stockholder, will enable us to continue planned operations 
through the first quarter of 2010. However, we cannot assure you that our plans will not change or that changed 
circumstances will not result in the depletion of our capital resources more rapidly than we currently anticipate. 
Accordingly, we plan to raise additional capital, either through the sale of equity and/or debt securities, a strategic 
business collaboration or the establishment of other funding facilities, in order to continue the development and 
commercialization of AFRESA and other product candidates and to support our other ongoing activities. However, 
due to current turbulence in the U.S. and global financial markets, it may be difficult for us to raise additional capital 
through the sale of equity and/or debt securities. The amount of additional funds we need will depend on a number of 
factors, including:  

(cid:129)   the rate of progress and costs of our clinical trials and research and development activities, including costs of 

procuring clinical materials and expanding our own manufacturing facilities;

(cid:129)   our success in establishing strategic business collaborations and the timing and amount of any payments we 

might receive from any collaboration we are able to establish;

(cid:129)   actions taken by the FDA and other regulatory authorities affecting our products and competitive products;

(cid:129)   our degree of success in commercializing AFRESA;

(cid:129)   the emergence of competing technologies and products and other adverse market developments;

(cid:129)   the timing and amount of payments we might receive from potential licensees;

(cid:129)   the costs of preparing, filing, prosecuting, maintaining and enforcing patent claims and other intellectual 

property rights or defending against claims of infringement by others;

(cid:129)   the costs of discontinuing projects and technologies or decommissioning existing facilities, if we undertake 

those activities; and

(cid:129)   the costs of performing additional clinical trials to demonstrate safety and efficacy if our current trials do not 

deliver results sufficient for FDA approval and commercialization.

     We have raised capital in the past primarily through the sale of equity securities and most currently through the 
sale of equity and debt securities. We may in the future pursue the sale of additional equity and/or debt securities, or 
the establishment of other funding facilities. Issuances of additional debt or equity securities or the conversion of any 
of our currently outstanding convertible debt securities into shares of our common stock could impact your rights as a 
holder of our common stock and may dilute your ownership percentage. Moreover, the establishment of other 
funding facilities may impose restrictions on our operations. These restrictions could include limitations on 
additional borrowing and specific restrictions on the use of our assets, as well as prohibitions on our ability to create 
liens, pay dividends, redeem our stock or make investments.  

     We also may seek to raise additional capital by pursuing opportunities for the licensing or sale of certain 
intellectual property and other assets, including our Technosphere technology platform. We cannot offer assurances, 
however, that any strategic collaborations, sales of securities or sales or licenses of assets will be available to us on a 
timely basis or on acceptable terms, if at all. We may be required to enter into relationships with third parties to 
develop or commercialize products or technologies that we otherwise would have sought to develop independently, 
and any such relationships may not be on terms as commercially favorable to us as might otherwise be the case.  

     In the event that sufficient additional funds are not obtained through strategic collaboration opportunities, sales of 
securities, licensing arrangements and/or asset sales on a timely basis, we may be required to reduce expenses 
through the delay, reduction or curtailment of our projects, including AFRESA commercialization, or further 
reduction of costs for facilities and administration. Moreover, if we do not obtain such additional funds, there will be 
substantial doubt about our ability to continue as a going concern.  

The current financial crisis and deteriorating economic conditions may have an adverse impact on the loan 
facility with an entity controlled by our principal stockholder, which we currently cannot predict.  

     As widely reported, economic conditions in the United States and globally have been deteriorating. Financial 
markets in the United States, Europe and Asia have been experiencing a period of unprecedented turmoil and 
upheaval characterized by extreme volatility and declines in security prices, severely diminished liquidity and credit 
availability, inability to access capital markets, the bankruptcy, failure, collapse or sale of various financial 
institutions and an unprecedented level of intervention from the United States federal government and other 
governments. We cannot predict the impact of these events on the loan facility with an entity controlled by our 
principal stockholder. If we are unable to draw on this financial resource, our business and financial condition will be 
adversely affected.  

We depend heavily on the successful development and commercialization of our lead product candidate, 
AFRESA, which has completed clinical development, and our other product candidates, which are in early 
clinical or preclinical development.  

     To date, we have not completed the development of any product candidates through to commercialization. 
AFRESA has completed pivotal Phase 3 clinical trials, while our other product candidates are generally in early 
clinical or preclinical development. We anticipate that in the near term, our ability to generate revenues will depend 
solely on the successful development and commercialization of AFRESA.  

     We have expended significant time, money and effort in the development of our lead product candidate, 
AFRESA, which has not yet received regulatory approval and which may never be commercialized. Before we can 
market and sell AFRESA, we must receive the necessary approvals from the FDA and similar foreign regulatory 
agencies before AFRESA can be marketed in the United States or elsewhere. Even if we were to receive regulatory 
approval, we ultimately may be unable to gain market acceptance of AFRESA for a variety of reasons, including the 
treatment and dosage regimen, potential adverse effects, the availability of alternative treatments and cost 
effectiveness. If we fail to commercialize AFRESA, our business, financial condition and results of operations will 
be materially and adversely affected.  

     We are seeking to develop and expand our portfolio of product candidates through our internal research programs 
and through licensing or otherwise acquiring the rights to therapeutics in the areas of cancer and other indications. 
All of these product candidates will require additional research and development and significant preclinical, clinical 
and other testing prior to seeking regulatory approval to market them. Accordingly, these product candidates will not 
be commercially available for a number of years, if at all.  

     A significant portion of the research that we are conducting involves new and unproven compounds and 
technologies, including AFRESA, Technosphere platform technology and immunotherapy product candidates. 
Research programs to identify new product candidates require substantial technical, financial and human resources. 
Even if our research programs identify candidates that initially show promise, these candidates may fail to progress 
to clinical development for any number of reasons, including discovery upon further research that these candidates 
have adverse effects or other characteristics that indicate they are unlikely to be effective. In  

22

addition, the clinical results we obtain at one stage are not necessarily indicative of future testing results. If we fail to 
successfully complete the development and commercialization of AFRESA or develop or expand our other product 
candidates, or are significantly delayed in doing so, our business and results of operations will be harmed and the 
value of our stock could decline.  

If we do not achieve our projected development and commercialization goals in the timeframes we announce and 
expect, our business would be harmed and the market price of our common stock could decline.  

     For planning purposes, we estimate the timing of the accomplishment of various scientific, clinical, regulatory and 
other product development goals, which we sometimes refer to as milestones. These milestones may include the 
commencement or completion of scientific studies and clinical trials and the submission of regulatory filings. From 
time to time, we publicly announce the expected timing of some of these milestones. All of these milestones are 
based on a variety of assumptions. The actual timing of the achievement of these milestones can vary dramatically 
from our estimates, in many cases for reasons beyond our control, depending on numerous factors, including:  

(cid:129)   the rate of progress, costs and results of our clinical trial and research and development activities, which will be 

impacted by the level of proficiency and experience of our clinical staff;

(cid:129)   our ability to identify and enroll patients who meet clinical trial eligibility criteria;

(cid:129)   our ability to access sufficient, reliable and affordable supplies of components used in the manufacture of our 

product candidates, including insulin and other materials for AFRESA;

(cid:129)   the costs of expanding and maintaining manufacturing operations, as necessary;

(cid:129)   the extent of scheduling conflicts with participating clinicians and clinical institutions;

(cid:129)   the receipt of approvals by our competitors and by us from the FDA and other regulatory agencies; and

(cid:129)   other actions by regulators.

     In addition, if we do not obtain sufficient additional funds through sales of securities, strategic collaborations or 
the license or sale of certain of our assets on a timely basis, we may be required to reduce expenses by delaying, 
reducing or curtailing our development of AFRESA or other product development activities, which would impact our 
ability to meet milestones. If we fail to commence or complete, or experience delays in or are forced to curtail, our 
proposed clinical programs or otherwise fail to adhere to our projected development goals in the timeframes we 
announce and expect, our business and results of operations will be harmed and the market price of our common 
stock may decline.  

We face substantial competition in the development of our product candidates and may not be able to compete 
successfully, and our product candidates may be rendered obsolete by rapid technological change.  

     A number of established pharmaceutical companies have or are developing technologies for the treatment of 
diabetes. We also face substantial competition for the development of our other product candidates.  

     Many of our existing or potential competitors have, or have access to, substantially greater financial, research and 
development, production, and sales and marketing resources than we do and have a greater depth and number of 
experienced managers. As a result, our competitors may be better equipped than we are to develop, manufacture, 
market and sell competing products. In addition, gaining favorable reimbursement is critical to the success of 
AFRESA. Many of our competitors have existing infrastructure and relationships with managed care organizations 
and reimbursement authorities which can be used to their advantage.  

     The rapid rate of scientific discoveries and technological changes could result in one or more of our product 
candidates becoming obsolete or noncompetitive. Our competitors may develop or introduce new products that 
render our technology and AFRESA less competitive, uneconomical or obsolete. Our future success will depend not 
only on our ability to develop our product candidates but to improve them and keep pace with emerging industry 
developments. We cannot assure you that we will be able to do so.  

     We also expect to face increasing competition from universities and other non-profit research organizations. 
These institutions carry out a significant amount of research and development in the areas of diabetes and cancer. 
These institutions are becoming increasingly

aware of the commercial value of their findings and are more active in seeking patent and other proprietary rights as 
well as licensing revenues.  

If we fail to enter into a strategic collaboration with respect to AFRESA, we may not be able to execute on our 
business model.  

     We have held extensive discussions with a number of pharmaceutical companies concerning a potential strategic 
business collaboration for AFRESA. To date, we have not reached agreement with any of these companies on a 
collaboration. On April 10, 2008, we announced our decision to suspend partnership discussions as we believed that, 
given the existing market conditions, we would have been unable to achieve an appropriate valuation for AFRESA 
until Phase 3 data were available. With our pivotal Phase 3 clinical trials now complete, we have restarted 
partnership discussions. In such discussions, we believe that we will have to expend significant additional time and 
effort before we could reach an agreement, and we cannot predict when, if ever, we could conclude such an 
agreement with a partner. There can be no assurance that any such collaboration will be available to us on a timely 
basis or on acceptable terms, if at all. If we are not able to enter into a collaboration on terms that are favorable to us, 
we may be unable to undertake and fund product development, clinical trials, manufacturing and marketing activities 
at our own expense. Accordingly, we may have to substantially reduce our development efforts, which would delay 
or otherwise impede the commercialization of AFRESA.  

     We will face similar challenges as we seek to develop our other product candidates. Our current strategy for 
developing, manufacturing and commercializing our other product candidates includes evaluating the potential for 
collaborating with pharmaceutical and biotechnology companies at some point in the drug development process and 
for these collaborators to undertake the advanced clinical development and commercialization of our product 
candidates. It may be difficult for us to find third parties that are willing to enter into collaborations on economic 
terms that are favorable to us, or at all. Failure to enter into a collaboration with respect to any other product 
candidate could substantially increase our requirements for capital and force us to substantially reduce our 
development effort.  

If we enter into collaborative agreements with respect to AFRESA and if our third-party collaborators do not 
perform satisfactorily or if our collaborations fail, development or commercialization of AFRESA may be 
delayed and our business could be harmed.  

     We currently rely on clinical research organizations and hospitals to conduct, supervise or monitor some or all 
aspects of clinical trials involving AFRESA. Further, we may also enter into license agreements, partnerships or 
other collaborative arrangements to support the financing, development and marketing of AFRESA. We may also 
license technology from others to enhance or supplement our technologies. These various collaborators may enter 
into arrangements that would make them potential competitors. These various collaborators also may breach their 
agreements with us and delay our progress or fail to perform under their agreements, which could harm our business. 

     If we enter into collaborative arrangements, we will have less control over the timing, planning and other aspects 
of our clinical trials, and the sale and marketing of AFRESA and our other product candidates. We cannot offer 
assurances that we will be able to enter into satisfactory arrangements with third parties as contemplated or that any 
of our existing or future collaborations will be successful.  

Continued testing of AFRESA or another product candidate may not yield successful results, and even if it does, 
we may still be unable to commercialize that product candidate.  

     Our research and development programs are designed to test the safety and efficacy of AFRESA and our other 
product candidates through extensive nonclinical and clinical testing. We may experience numerous unforeseen 
events during, or as a result of, the testing process that could delay or prevent commercialization of AFRESA or any 
of our other product candidates, including the following:  

(cid:129)   safety and efficacy results obtained in our nonclinical and initial clinical testing may be inconclusive or may not 
be predictive of results obtained in later-stage clinical trials or following long-term use, and we may as a result 
be forced to stop developing product candidates that we currently believe are important to our future;

(cid:129)   the data collected from clinical trials of our product candidates may not be sufficient to support FDA or other 

regulatory approval;

(cid:129)   after reviewing test results, we or any potential collaborators may abandon projects that we previously believed 

were promising; and

24

                                   
 
 
 
 
 
Table of Contents 

(cid:129)   our product candidates may not produce the desired effects or may result in adverse health effects or other 

characteristics that preclude regulatory approval or limit their commercial use if approved.

     We have completed a pivotal Phase 3 safety study of AFRESA to evaluate pulmonary function over a period of 
two years, but AFRESA is intended for multiple uses per day. Due to the size and timeframe over which existing and 
planned clinical trials are conducted, the results of clinical trials, including our existing Phase 3 clinical trials, may 
not be indicative of the effects of the use of AFRESA over longer terms. If use of AFRESA results in adverse health 
effects or reduced efficacy or both, the FDA or other regulatory agencies may terminate our ability to market and sell 
AFRESA, may narrow the approved indications for use or otherwise require restrictive product labeling or 
marketing, or may require further clinical trials, which may be time-consuming and expensive and may not produce 
favorable results.  

     As a result of any of these events, we, any collaborator, the FDA, or any other regulatory authorities, may suspend 
or terminate clinical trials or marketing of AFRESA at any time. Any suspension or termination of our clinical trials 
or marketing activities may harm our business and results of operations and the market price of our common stock 
may decline.  

If we are unable to transition successfully from an early-stage development company to a company that 
commercializes therapeutics, our operations would suffer.  

     We are at a critical juncture in our development, as we prepare to submit our first NDA. We require a well-
structured plan to make this transition. We have a number of executive personnel, particularly in clinical 
development, regulatory and manufacturing production, including personnel with significant Phase 3-to-
commercialization experience. We have aligned our management structure to accommodate the increasing 
complexity of our operations, and we have implemented the following measures, among others, to accommodate our 
transition, complete development of AFRESA and successfully implement our commercialization strategy for 
AFRESA:  

(cid:129)   expand our manufacturing capabilities;

(cid:129)   develop comprehensive and detailed commercialization, clinical development and regulatory plans; and

(cid:129)   implement standard operating procedures, including those for protocol development.

     If we are unable to accomplish these measures in a timely manner, we would be at considerable risk of failing to:  

(cid:129)   develop manufacturing capabilities to be ready for FDA inspection and commercial operations; and

(cid:129)   develop the key clinical data needed to obtain regulatory approval and compete successfully in the marketplace.

If our suppliers fail to deliver materials and services needed for the production of AFRESA in a timely and 
sufficient manner, or they fail to comply with applicable regulations, our business and results of operations 
would be harmed and the market price of our common stock could decline.  

     For AFRESA to be commercially viable, we need access to sufficient, reliable and affordable supplies of insulin, 
our AFRESA inhaler, the related cartridges and other materials. In November 2007, we entered into a long-term 
supply agreement with N.V. Organon, which is currently our sole supplier for insulin. We are aware of several other 
suppliers of bulk insulin, but to date we have not entered into a commercial relationship with any of them. We have 
obtained our AFRESA precursor raw material from two sources: Evonik Industries and Lonza, Ltd., both are major 
chemical manufacturers with facilities in Europe and North America. We also utilize our in-house chemical 
manufacturing plant as a back up facility. We believe both manufacturers have the capacity to supply our current 
clinical and future commercial requirements. We have obtained our AFRESA inhaler and cartridges from both 
Vaupell, Inc., and Rexam PLC. We must rely on our suppliers to comply with relevant regulatory and other legal 
requirements, including the production of insulin in accordance with cGMP and the production of AFRESA inhaler 
and related cartridges in accordance with device QSR. The supply of all of these materials may be limited or the 
manufacturer may not meet relevant regulatory requirements, and if we are unable to obtain these materials in 
sufficient amounts, in a timely manner and at reasonable prices, or if we should encounter delays or difficulties in our 
relationships with manufacturers or suppliers, the development or manufacturing of AFRESA may be delayed. Any 
such events would delay the submission of AFRESA for regulatory approval or  

25

market introduction and subsequent sales and, if so, our business and results of operations will be harmed and the 
market price of our common stock may decline.  

We have never manufactured AFRESA or any other product candidate in commercial quantities, and if we fail 
to develop an effective manufacturing capability for our product candidates or to engage third-party 
manufacturers with this capability, we may be unable to commercialize these products.  

     We have obtained our AFRESA precursor raw material from two sources, Evonik Industries and Lonza Ltd. We 
use our Danbury, Connecticut facility to formulate AFRESA, fill plastic cartridges with AFRESA and blister 
package the cartridges for our clinical trials. We are presently increasing our formulation, fill and finishing 
capabilities at Danbury in order to accommodate our activities through initial commercialization. This expansion will 
involve a number of third-party suppliers of equipment and materials as well as engineering and construction 
services. Our suppliers may not deliver all of the required equipment, materials and services in a timely manner or at 
reasonable prices. If we encounter difficulties in our relationships with these suppliers, or if a supplier becomes 
unable to provide us with goods or services at the agreed-upon terms or schedule, our facilities expansion could be 
delayed or its costs increased.  

     We have never manufactured AFRESA or any other product candidate in commercial quantities. As our product 
candidates move through the regulatory process, we will need to either develop the capability of manufacturing on a 
commercial scale or engage third-party manufacturers with this capability, and we cannot offer assurances that we 
will be able to do either successfully. The manufacture of pharmaceutical products requires significant expertise and 
capital investment, including the development of advanced manufacturing techniques and process controls. 
Manufacturers of pharmaceutical products often encounter difficulties in production, especially in scaling up initial 
production. These problems include difficulties with production costs and yields, quality control and assurance and 
shortages of qualified personnel, as well as compliance with strictly enforced federal, state and foreign regulations. In 
addition, before we would be able to produce commercial quantities of AFRESA at our Danbury facility, it would 
have to undergo a pre-approval inspection by the FDA. If we use a third-party supplier to formulate AFRESA or 
produce raw material, the transition could also require significant start-up time to qualify and implement the 
manufacturing process. If we engage a third-party manufacturer, our third-party manufacturer may not perform as 
agreed or may terminate its agreement with us.  

     Additionally, if we manufacture commercial material at a different facility than the site of manufacture of clinical 
trial materials or if we manufacture commercial material on a significantly larger production scale than the 
production scale for clinical trial materials, we may be required by the FDA to establish that the results obtained from 
the clinical trials may reasonably be extrapolated to such commercial material.  

     Any of these factors could cause us to delay or suspend clinical trials, regulatory submissions, required approvals 
or commercialization of our product candidates, entail higher costs and result in our being unable to effectively 
commercialize our products. Furthermore, if we or a third-party manufacturer fail to deliver the required commercial 
quantities of any product on a timely basis, and at commercially reasonable prices and acceptable quality, and we 
were unable to promptly find one or more replacement manufacturers capable of production at a substantially 
equivalent cost, in substantially equivalent volume and quality on a timely basis, we would likely be unable to meet 
demand for such products and we would lose potential revenues..  

We deal with hazardous materials and must comply with environmental laws and regulations, which can be 
expensive and restrict how we do business.  

     Our research and development work involves the controlled storage and use of hazardous materials, including 
chemical, radioactive and biological materials. In addition, our manufacturing operations involve the use of CBZ-
lysine, which is stable and non-hazardous under normal storage conditions, but may form an explosive mixture under 
certain conditions. Our operations also produce hazardous waste products. We are subject to federal, state and local 
laws and regulations governing how we use, manufacture, store, handle and dispose of these materials. Moreover, the 
risk of accidental contamination or injury from hazardous materials cannot be completely eliminated, and in the 
event of an accident, we could be held liable for any damages that may result, and any liability could fall outside the 
coverage or exceed the limits of our insurance. Currently, our general liability policy provides coverage up to 
$1 million per occurrence and $2 million in the aggregate and is supplemented by an umbrella policy that provides a 
further $4 million of coverage; however, our insurance policy excludes pollution coverage and we do not carry a 
separate hazardous materials policy. In addition, we could be required to incur significant costs to comply with 
environmental laws and regulations in the future. Finally, current or future environmental laws and regulations may 
impair our research, development or production efforts.

     When we purchased the facilities located in Danbury, Connecticut in 2001, there was a soil cleanup plan in 
process. As part of the purchase, we obtained an indemnification from the seller related to the remediation of the soil 
for all known environmental conditions that existed at the time the seller acquired the property. The seller is, in turn, 
indemnified for these known environmental conditions by the previous owner. We completed the final stages of the 
soil cleanup plan in the third quarter of 2008 which cost approximately $2.25 million. We have also received an 
indemnification from the seller for environmental conditions created during its ownership of the property and for 
environmental problems unknown at the time that the seller acquired the property. These additional indemnities are 
limited to the purchase price that we paid for the Danbury facilities. We are currently pursuing collection of the 
clean-up costs and expenses from the seller or the party responsible for the contamination. If we are unable to collect 
the full amount of these costs and expenses, our business and results of operations may be harmed.  

If we fail to enter into collaborations with third parties, we would be required to establish our own sales, 
marketing and distribution capabilities, which could impact the commercialization of our products and harm our 
business.  

     Our products will be used by a large number of healthcare professionals who require substantial education and 
support. For example, a broad base of physicians, including primary care physicians and endocrinologists, treat 
patients with diabetes. A large sales force will be required in order to educate these physicians about the benefits and 
advantages of AFRESA and to provide adequate support for them. Therefore, we plan to enter into collaborations 
with one or more pharmaceutical companies to market, distribute and sell AFRESA, if it is approved. If we fail to 
enter into collaborations, we would be required to establish our own direct sales, marketing and distribution 
capabilities. Establishing these capabilities can be time-consuming and expensive. Because we lack experience in 
selling pharmaceutical products to the diabetes market, we would be at a disadvantage compared to our potential 
competitors, all of whom have substantially more resources and experience than we do. For example, several other 
companies selling products to treat diabetes have existing sales forces in excess of 1,500 sales representatives. We, 
acting alone, would not initially be able to field a sales force as large as our competitors or provide the same degree 
of market research or marketing support. Also, we would not be able to match our competitor’s spending levels for 
pre-launch marketing preparation, including medical education. We cannot assure you that we will succeed in 
entering into acceptable collaborations, that any such collaboration will be successful or, if not, that we will 
successfully develop our own sales, marketing and distribution capabilities.  

If any product that we may develop does not become widely accepted by physicians, patients, third-party payers 
and the healthcare community, we may be unable to generate significant revenue, if any.  

     AFRESA and our other product candidates are new and unproven. Even if any of our product candidates obtains 
regulatory approvals, it may not gain market acceptance among physicians, patients, third-party payers and the 
healthcare community. Failure to achieve market acceptance would limit our ability to generate revenue and would 
adversely affect our results of operations.  

     The degree of market acceptance of AFRESA and our other product candidates will depend on many factors, 
including the:  

(cid:129)   claims for which FDA approval can be obtained, including superiority claims;

(cid:129)   perceived advantages and disadvantages of competitive products;

(cid:129)   willingness and ability of patients and the healthcare community to adopt new technologies;

(cid:129)   ability to manufacture the product in sufficient quantities with acceptable quality and at an acceptable cost;

(cid:129)   perception of patients and the healthcare community, including third-party payers, regarding the safety, efficacy 

and benefits of the product compared to those of competing products or therapies;

(cid:129)   convenience and ease of administration of the product relative to existing treatment methods;

(cid:129)   pricing and reimbursement of the product relative to existing treatment therapeutics and methods; and

(cid:129)   marketing and distribution support for the product.

     Physicians will not recommend a product until clinical data or other factors demonstrate the safety and efficacy of 
the product as compared to other treatments. Even if the clinical safety and efficacy of our product candidates is 
established, physicians may elect not to recommend these product candidates for a variety of factors, including the 
reimbursement policies of government and third-party  

27

payers and the effectiveness of our competitors in marketing their therapies. Because of these and other factors, any 
product that we may develop may not gain market acceptance, which would materially harm our business, financial 
condition and results of operations.  

If third-party payers do not reimburse customers for our products, our products might not be used or purchased, 
which would adversely affect our revenues.  

     Our future revenues and potential for profitability may be affected by the continuing efforts of governments and 
third-party payers to contain or reduce the costs of healthcare through various means. For example, in certain foreign 
markets the pricing of prescription pharmaceuticals is subject to governmental control. In the United States, there has 
been, and we expect that there will continue to be, a number of federal and state proposals to implement similar 
governmental controls. We cannot be certain what legislative proposals will be adopted or what actions federal, state 
or private payers for healthcare goods and services may take in response to any healthcare reform proposals or 
legislation. Such reforms may make it difficult to complete the development and testing of AFRESA and our other 
product candidates, and therefore may limit our ability to generate revenues from sales of our product candidates and 
achieve profitability. Further, to the extent that such reforms have a material adverse effect on the business, financial 
condition and profitability of other companies that are prospective collaborators for some of our product candidates, 
our ability to commercialize our product candidates under development may be adversely affected.  

     In the United States and elsewhere, sales of prescription pharmaceuticals still depend in large part on the 
availability of reimbursement to the consumer from third-party payers, such as governmental and private insurance 
plans. Third-party payers are increasingly challenging the prices charged for medical products and services. In 
addition, because each third-party payer individually approves reimbursement, obtaining these approvals is a time-
consuming and costly process. We would be required to provide scientific and clinical support for the use of any 
product to each third-party payer separately with no assurance that approval would be obtained. This process could 
delay the market acceptance of any product and could have a negative effect on our future revenues and operating 
results. Even if we succeed in bringing one or more products to market, we cannot be certain that any such products 
would be considered cost-effective or that reimbursement to the consumer would be available, in which case our 
business and results of operations would be harmed and the market price of our common stock could decline.  

If product liability claims are brought against us, we may incur significant liabilities and suffer damage to our 
reputation.  

     The testing, manufacturing, marketing and sale of AFRESA and our other product candidates expose us to 
potential product liability claims. A product liability claim may result in substantial judgments as well as consume 
significant financial and management resources and result in adverse publicity, decreased demand for a product, 
injury to our reputation, withdrawal of clinical trial volunteers and loss of revenues. We currently carry worldwide 
liability insurance in the amount of $10 million. We believe these limits are reasonable to cover us from potential 
damages arising from current and previous clinical trials of AFRESA. In addition, we carry local policies per trial in 
each country in which we conduct clinical trials that require us to carry coverage based on local statutory 
requirements. We intend to obtain product liability coverage for commercial sales in the future if AFRESA is 
approved. However, we may not be able to obtain insurance coverage that will be adequate to satisfy any liability 
that may arise, and because insurance coverage in our industry can be very expensive and difficult to obtain, we 
cannot assure you that we will be able to obtain sufficient coverage at an acceptable cost, if at all. If losses from such 
claims exceed our liability insurance coverage, we may ourselves incur substantial liabilities. If we are required to 
pay a product liability claim our business and results of operations would be harmed and the market price of our 
common stock may decline.  

If we lose any key employees or scientific advisors, our operations and our ability to execute our business 
strategy could be materially harmed.  

     In order to commercialize our product candidates successfully, we will be required to expand our work force, 
particularly in the areas of manufacturing, clinical trials management, regulatory affairs, business development, and 
sales and marketing. These activities will require the addition of new personnel, including management, and the 
development of additional expertise by existing personnel. We face intense competition for qualified employees 
among companies in the biotechnology and biopharmaceutical industries. Our success depends upon our ability to 
attract, retain and motivate highly skilled employees. We may be unable to attract and retain these individuals on 
acceptable terms, if at all.  

     The loss of the services of any principal member of our management and scientific staff could significantly delay 
or prevent the achievement of our scientific and business objectives. All of our employees are “at will” and we 
currently do not have employment agreements with any of the principal members of our management or scientific 
staff, and we do not have key person life insurance to  

28

                                   
Table of Contents 

cover the loss of any of these individuals. Replacing key employees may be difficult and time-consuming because of 
the limited number of individuals in our industry with the skills and experience required to develop, gain regulatory 
approval of and commercialize our product candidates successfully.  

     We have relationships with scientific advisors at academic and other institutions to conduct research or assist us in 
formulating our research, development or clinical strategy. These scientific advisors are not our employees and may 
have commitments to, and other obligations with, other entities that may limit their availability to us. We have 
limited control over the activities of these scientific advisors and can generally expect these individuals to devote 
only limited time to our activities. Failure of any of these persons to devote sufficient time and resources to our 
programs could harm our business. In addition, these advisors are not prohibited from, and may have arrangements 
with, other companies to assist those companies in developing technologies that may compete with our product 
candidates.  

If our Chief Executive Officer is unable to devote sufficient time and attention to our business, our operations 
and our ability to execute our business strategy could be materially harmed.  

     Alfred Mann, our Chairman and Chief Executive Officer, is involved in many other business and charitable 
activities. As a result, the time and attention Mr. Mann devotes to the operation of our business varies, and he may 
not expend the same time or focus on our activities as other, similarly situated chief executive officers. If Mr. Mann 
is unable to devote the time and attention necessary to running our business, we may not be able to execute our 
business strategy and our business could be materially harmed.  

Our facilities that are located in Southern California may be affected by man-made or natural disasters.  

     Our headquarters and some of our research and development activities are located in Southern California, where 
they are subject to a risk of man-made disasters, terrorism, and an enhanced risk of natural and other disasters such as 
fires, power and telecommunications failures, mudslides, and earthquakes. An act of terrorism, fire, earthquake or 
other catastrophic loss that causes significant damage to our facilities or interruption of our business could harm our 
business. We do not carry insurance to cover losses caused by earthquakes, and the insurance coverage that we carry 
for fire damage and for business interruption may be insufficient to compensate us for any losses that we may incur.  

If our internal controls over financial reporting are not considered effective, our business and stock price could 
be adversely affected.  

     Section 404 of the Sarbanes-Oxley Act of 2002 requires us to evaluate the effectiveness of our internal controls 
over financial reporting as of the end of each fiscal year, and to include a management report assessing the 
effectiveness of our internal controls over financial reporting in our annual report on Form 10-K for that fiscal year. 
Section 404 also requires our independent registered public accounting firm to attest to, and report on, our internal 
controls over financial reporting.  

     Our management, including our Chief Executive Officer and Chief Financial Officer, does not expect that our 
internal controls over financial reporting will prevent all errors and all fraud. A control system, no matter how well 
designed and operated, can provide only reasonable, not absolute, assurance that the control system’s objectives will 
be met. Further, the design of a control system must reflect the fact that there are resource constraints, and the 
benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control 
systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud 
involving a company have been, or will be, detected. The design of any system of controls is based in part on certain 
assumptions about the likelihood of future events, and we cannot assure you that any design will succeed in 
achieving its stated goals under all potential future conditions. Over time, controls may become inadequate because 
of changes in conditions or deterioration in the degree of compliance with policies or procedures. Because of the 
inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be 
detected. We cannot assure you that we or our independent registered public accounting firm will not identify a 
material weakness in our internal controls in the future. A material weakness in our internal controls over financial 
reporting would require management and our independent registered public accounting firm to evaluate our internal 
controls as ineffective. If our internal controls over financial reporting are not considered effective, we may 
experience a loss of public confidence, which could have an adverse effect on our business and on the market price 
of our common stock.

RISKS RELATED TO REGULATORY APPROVALS  

Our product candidates must undergo rigorous nonclinical and clinical testing and we must obtain regulatory 
approvals, which could be costly and time-consuming and subject us to unanticipated delays or prevent us from 
marketing any products.  

     Our research and development activities, as well as the manufacturing and marketing of our product candidates, 
including AFRESA, are subject to regulation, including regulation for safety, efficacy and quality, by the FDA in the 
United States and comparable authorities in other countries. FDA regulations and the regulation of comparable 
foreign regulatory authorities are wide-ranging and govern, among other things:  

(cid:129)   product design, development, manufacture and testing;

(cid:129)   product labeling;

(cid:129)   product storage and shipping;

(cid:129)   pre-market clearance or approval;

(cid:129)   advertising and promotion; and

(cid:129)   product sales and distribution.

     Clinical testing can be costly and take many years, and the outcome is uncertain and susceptible to varying 
interpretations. Based on our discussions with the FDA at a pre-NDA meeting, we conducted a study, prior to 
submitting our NDA, that assessed the bioequivalency of the inhaler used in our clinical trials to date with the 
modified version of the same inhaler that we intend to use for commercial purposes. The FDA did not request any 
other trials prior to NDA submission. However, we cannot be certain when the FDA might request additional studies, 
under what conditions such studies might be requested, or what the size or length of any such studies might be. The 
clinical trials of our product candidates may not be completed on schedule, the FDA or foreign regulatory agencies 
may order us to stop or modify our research, or these agencies may not ultimately approve any of our product 
candidates for commercial sale. The data collected from our clinical trials may not be sufficient to support regulatory 
approval of our various product candidates, including AFRESA. Even if we believe the data collected from our 
clinical trials are sufficient, the FDA has substantial discretion in the approval process and may disagree with our 
interpretation of the data. Our failure to adequately demonstrate the safety and efficacy of any of our product 
candidates would delay or prevent regulatory approval of our product candidates, which could prevent us from 
achieving profitability.  

     The requirements governing the conduct of clinical trials and manufacturing and marketing of our product 
candidates, including AFRESA, outside the United States vary widely from country to country. Foreign approvals 
may take longer to obtain than FDA approvals and can require, among other things, additional testing and different 
clinical trial designs. Foreign regulatory approval processes include all of the risks associated with the FDA approval 
processes. Some of those agencies also must approve prices of the products. Approval of a product by the FDA does 
not ensure approval of the same product by the health authorities of other countries. In addition, changes in 
regulatory policy in the United States or in foreign countries for product approval during the period of product 
development and regulatory agency review of each submitted new application may cause delays or rejections.  

     The process of obtaining FDA and other required regulatory approvals, including foreign approvals, is expensive, 
often takes many years and can vary substantially based upon the type, complexity and novelty of the products 
involved. We are not aware of any precedent for the successful commercialization of products based on our 
technology. On January 26, 2006, the FDA approved the first pulmonary insulin product, Exubera. This approval has 
had an impact on and, notwithstanding the voluntary withdrawal of the product from the market by its manufacturer, 
could still impact the development and registration of AFRESA in different ways, including: Exubera may be used as 
a reference for safety and efficacy evaluations of AFRESA, and the approval standards set for Exubera may be 
applied to other products that follow including AFRESA. The FDA has advised us that it will regulate AFRESA as a 
“combination product” because of the complex nature of the system that includes the combination of a new drug 
(AFRESA) and a new medical device (the AFRESA inhaler used to administer the insulin). The FDA indicated that 
the review of a future drug marketing application for AFRESA will involve three separate review groups of the FDA: 
(1) the Metabolic and Endocrine Drug Products Division; (2) the Pulmonary Drug Products Division; and (3) the 
Center for Devices and Radiological Health within the FDA that reviews medical devices. We currently understand 
that the Metabolic and Endocrine Drug Products Division will be the lead group and will obtain consulting reviews 
from the other two FDA groups. The FDA has not made an official final decision in this regard, however, and we  

30

                                   
 
 
 
 
 
 
 
 
 
 
 
Table of Contents 

can make no assurances at this time about what impact FDA review by multiple groups will have on the review and 
approval of our product or whether we are correct in our understanding of how AFRESA will be reviewed and 
approved.  

     Also, questions that have been raised about the safety of marketed drugs generally, including pertaining to the 
lack of adequate labeling, may result in increased cautiousness by the FDA in reviewing new drugs based on safety, 
efficacy, or other regulatory considerations and may result in significant delays in obtaining regulatory approvals. 
Such regulatory considerations may also result in the imposition of more restrictive drug labeling or marketing 
requirements as conditions of approval, which may significantly affect the marketability of our drug products. FDA 
review of AFRESA as a combination product therapy may lengthen the product development and regulatory 
approval process, increase our development costs and delay or prevent the commercialization of AFRESA.  

     We are developing AFRESA as a new treatment for diabetes utilizing unique, proprietary components. As a 
combination product, any changes to either the AFRESA inhaler, or AFRESA, including new suppliers, could 
possibly result in FDA requirements to repeat certain clinical studies. This means, for example, that switching to an 
alternate delivery system could require us to undertake additional clinical trials and other studies, which could 
significantly delay the development and commercialization of AFRESA. Our product candidates that are currently in 
development for the treatment of cancer also face similar obstacles and costs.  

     We currently expect that our inhaler will be reviewed for approval as part of the NDA for AFRESA. No 
assurances exist that we will not be required to obtain separate device clearances or approval for use of our inhaler 
with AFRESA. This may result in our being subject to medical device review user fees and to other device 
requirements to market our inhaler and may result in significant delays in commercialization. Even if the device 
component is approved as part of our NDA for AFRESA, numerous device regulatory requirements still apply to the 
device part of the drug-device combination.  

We have only limited experience in filing and pursuing applications necessary to gain regulatory approvals, 
which may impede our ability to obtain timely approvals from the FDA or foreign regulatory agencies, if at all.  

     We will not be able to commercialize AFRESA or any other product candidates until we have obtained regulatory 
approval. We have no experience as a company in late-stage regulatory filings, such as preparing and submitting 
NDAs, which may place us at risk of delays, overspending and human resources inefficiencies. Any delay in 
obtaining, or inability to obtain, regulatory approval could harm our business.  

If we do not comply with regulatory requirements at any stage, whether before or after marketing approval is 
obtained, we may be subject to criminal prosecution, fined or forced to remove a product from the market or 
experience other adverse consequences, including restrictions or delays in obtaining regulatory marketing 
approval.  

     Even if we comply with regulatory requirements, we may not be able to obtain the labeling claims necessary or 
desirable for product promotion. We may also be required to undertake post-marketing trials. In addition, if we or 
other parties identify adverse effects after any of our products are on the market, or if manufacturing problems occur, 
regulatory approval may be withdrawn and a reformulation of our products, additional clinical trials, changes in 
labeling of, or indications of use for, our products and/or additional marketing applications may be required. If we 
encounter any of the foregoing problems, our business and results of operations will be harmed and the market price 
of our common stock may decline.  

Even if we obtain regulatory approval for our product candidates, such approval may be limited and we will be 
subject to stringent, ongoing government regulation.  

     Even if regulatory authorities approve any of our product candidates, they could approve less than the full scope 
of uses or labeling that we seek or otherwise require special warnings or other restrictions on use or marketing or 
could require potentially costly post-marketing follow-up clinical trials. Regulatory authorities may limit the 
segments of the diabetes population to which we or others may market AFRESA or limit the target population for our 
other product candidates. Based on currently available clinical studies, we believe that AFRESA may have certain 
advantages over currently approved insulin products including its approximation of the natural early insulin secretion 
normally seen in healthy individuals following the beginning of a meal. Nonetheless, there are no assurances that 
these and other advantages, if any, of AFRESA have clinical significance or can be confirmed in head-to-head 
clinical trials against appropriate approved comparator insulin drug products. Such comparative clinical trials are 
required to make these types of superiority claims in labeling or advertising. These aforementioned observations and 
others may therefore not be capable of substantiation in comparative clinical trials prior to our NDA submission, if at 
all, or otherwise may not be suitable for inclusion in  

31

                                   
Table of Contents 

product labeling or advertising and, as a result, AFRESA may not have competitive advantages when compared to 
other insulin products.  

     The manufacture, marketing and sale of these product candidates will be subject to stringent and ongoing 
government regulation. The FDA may also withdraw product approvals if problems concerning safety or efficacy of 
the product occur following approval. In response to questions that have been raised about the safety of certain 
approved prescription products, including the lack of adequate warnings, the FDA and United States Congress are 
currently considering new regulatory and legislative approaches to advertising, monitoring and assessing the safety 
of marketed drugs, including legislation providing the FDA with authority to mandate labeling changes for approved 
pharmaceutical products, particularly those related to safety. We also cannot be sure that the current FDA and United 
States Congressional initiatives pertaining to ensuring the safety of marketed drugs or other developments pertaining 
to the pharmaceutical industry will not adversely affect our operations.  

     We also are required to register our establishments and list our products with the FDA and certain state agencies. 
We and any third-party manufacturers or suppliers must continually adhere to federal regulations setting forth 
requirements, known as cGMP (for drugs) and QSR (for medical devices), and their foreign equivalents, which are 
enforced by the FDA and other national regulatory bodies through their facilities inspection programs. If our 
facilities, or the facilities of our manufacturers or suppliers, cannot pass a preapproval plant inspection, the FDA will 
not approve the marketing of our product candidates. In complying with cGMP and foreign regulatory requirements, 
we and any of our potential third-party manufacturers or suppliers will be obligated to expend time, money and effort 
in production, record-keeping and quality control to ensure that our products meet applicable specifications and other 
requirements. QSR requirements also impose extensive testing, control and documentation requirements. State 
regulatory agencies and the regulatory agencies of other countries have similar requirements. In addition, we will be 
required to comply with regulatory requirements of the FDA, state regulatory agencies and the regulatory agencies of 
other countries concerning the reporting of adverse events and device malfunctions, corrections and removals (e.g., 
recalls), promotion and advertising and general prohibitions against the manufacture and distribution of adulterated 
and misbranded devices. Failure to comply with these regulatory requirements could result in civil fines, product 
seizures, injunctions and/or criminal prosecution of responsible individuals and us. Any such actions would have a 
material adverse effect on our business and results of operations.  

Our insulin supplier does not yet supply human recombinant insulin for an FDA-approved product and will 
likely be subject to an FDA preapproval inspection before the agency will approve a future marketing application 
for AFRESA.  

     Our insulin supplier sells its product outside of the United States. However, we can make no assurances that our 
insulin supplier will be acceptable to the FDA. If we were required to find a new or additional supplier of insulin, we 
would be required to evaluate the new supplier’s ability to provide insulin that meets our specifications and quality 
requirements, which would require significant time and expense and could delay the manufacturing and future 
commercialization of AFRESA. We also depend on suppliers for other materials that comprise AFRESA, including 
our AFRESA inhaler and cartridges. All of our device suppliers must comply with relevant regulatory requirements 
including QSR. It also is likely that major suppliers will be subject to FDA preapproval inspections before the agency 
will approve a future marketing application for AFRESA. At the present time our insulin supplier is certified to the 
ISO9001:2000 Standard. There can be no assurance, however, that if the FDA were to conduct a preapproval 
inspection of our insulin supplier or other suppliers, that the agency would find that the supplier substantially comply 
with the QSR or cGMP requirements, where applicable. If we or any potential third-party manufacturer or supplier 
fails to comply with these requirements or comparable requirements in foreign countries, regulatory authorities may 
subject us to regulatory action, including criminal prosecutions, fines and suspension of the manufacture of our 
products.  

Reports of side effects or safety concerns in related technology fields or in other companies’ clinical trials could 
delay or prevent us from obtaining regulatory approval or negatively impact public perception of our product 
candidates.  

     At present, there are a number of clinical trials being conducted by us and other pharmaceutical companies 
involving insulin delivery systems. If we discover that AFRESA is associated with a significantly increased 
frequency of adverse events, or if other pharmaceutical companies announce that they observed frequent adverse 
events in their trials involving the pulmonary delivery of insulin, we could encounter delays in the timing of our 
clinical trials or difficulties in obtaining the approval of AFRESA. As well, the public perception of AFRESA might 
be adversely affected, which could harm our business and results of operations and cause the market price of our 
common stock to decline, even if the concern relates to another company’s products or product candidates.  

     There are also a number of clinical trials being conducted by other pharmaceutical companies involving 
compounds similar to, or competitive with, our other product candidates. Adverse results reported by these other 
companies in their clinical trials could delay or  

32

                                   
Table of Contents 

prevent us from obtaining regulatory approval or negatively impact public perception of our product candidates, 
which could harm our business and results of operations and cause the market price of our common stock to decline.  

RISKS RELATED TO INTELLECTUAL PROPERTY  

If we are unable to protect our proprietary rights, we may not be able to compete effectively, or operate 
profitably.  

     Our commercial success depends, in large part, on our ability to obtain and maintain intellectual property 
protection for our technology. Our ability to do so will depend on, among other things, complex legal and factual 
questions, and it should be noted that the standards regarding intellectual property rights in our fields are still 
evolving. We attempt to protect our proprietary technology through a combination of patents, trade secrets and 
confidentiality agreements. We own a number of domestic and international patents, have a number of domestic and 
international patent applications pending and have licenses to additional patents. We cannot assure you that our 
patents and licenses will successfully preclude others from using our technologies, and we could incur substantial 
costs in seeking enforcement of our proprietary rights against infringement. Even if issued, the patents may not give 
us an advantage over competitors with similar alternative technologies.  

     Moreover, the issuance of a patent is not conclusive as to its validity or enforceability and it is uncertain how 
much protection, if any, will be afforded by our patents. A third party may challenge the validity or enforceability of 
a patent after its issuance by various proceedings such as oppositions in foreign jurisdictions or re-examinations in 
the United States. If we attempt to enforce our patents, they may be challenged in court where they could be held 
invalid, unenforceable, or have their breadth narrowed to an extent that would destroy their value.  

     We also rely on unpatented technology, trade secrets, know-how and confidentiality agreements. We require our 
officers, employees, consultants and advisors to execute proprietary information and invention and assignment 
agreements upon commencement of their relationships with us. We also execute confidentiality agreements with 
outside collaborators. There can be no assurance, however, that these agreements will provide meaningful protection 
for our inventions, trade secrets, know-how or other proprietary information in the event of unauthorized use or 
disclosure of such information. If any trade secret, know-how or other technology not protected by a patent were to 
be disclosed to or independently developed by a competitor, our business, results of operations and financial 
condition could be adversely affected.  

If we become involved in lawsuits to protect or enforce our patents or the patents of our collaborators or 
licensors, we would be required to devote substantial time and resources to prosecute or defend such 
proceedings.  

     Competitors may infringe our patents or the patents of our collaborators or licensors. To counter infringement or 
unauthorized use, we may be required to file infringement claims, which can be expensive and time-consuming. In 
addition, in an infringement proceeding, a court may decide that a patent of ours is not valid or is unenforceable, or 
may refuse to stop the other party from using the technology at issue on the grounds that our patents do not cover its 
technology. A court may also decide to award us a royalty from an infringing party instead of issuing an injunction 
against the infringing activity. An adverse determination of any litigation or defense proceedings could put one or 
more of our patents at risk of being invalidated or interpreted narrowly and could put our patent applications at risk 
of not issuing.  

     Interference proceedings brought by the USPTO may be necessary to determine the priority of inventions with 
respect to our patent applications or those of our collaborators or licensors. Litigation or interference proceedings 
may fail and, even if successful, may result in substantial costs and be a distraction to our management. We may not 
be able, alone or with our collaborators and licensors, to prevent misappropriation of our proprietary rights, 
particularly in countries where the laws may not protect such rights as fully as in the United States. We may not 
prevail in any litigation or interference proceeding in which we are involved. Even if we do prevail, these 
proceedings can be very expensive and distract our management.  

     Furthermore, because of the substantial amount of discovery required in connection with intellectual property 
litigation, there is a risk that some of our confidential information could be compromised by disclosure during this 
type of litigation. In addition, during the course of this kind of litigation, there could be public announcements of the 
results of hearings, motions or other interim proceedings or developments. If securities analysts or investors perceive 
these results to be negative, the market price of our common stock may decline.  

33

                                   
Table of Contents 

If our technologies conflict with the proprietary rights of others, we may incur substantial costs as a result of 
litigation or other proceedings and we could face substantial monetary damages and be precluded from 
commercializing our products, which would materially harm our business.  

     Over the past three decades the number of patents issued to biotechnology companies has expanded dramatically. 
As a result it is not always clear to industry participants, including us, which patents cover the multitude of 
biotechnology product types. Ultimately, the courts must determine the scope of coverage afforded by a patent and 
the courts do not always arrive at uniform conclusions.  

     A patent owner may claim that we are making, using, selling or offering for sale an invention covered by the 
owner’s patents and may go to court to stop us from engaging in such activities. Such litigation is not uncommon in 
our industry.  

     Patent lawsuits can be expensive and would consume time and other resources. There is a risk that a court would 
decide that we are infringing a third party’s patents and would order us to stop the activities covered by the patents, 
including the commercialization of our products. In addition, there is a risk that we would have to pay the other party 
damages for having violated the other party’s patents (which damages may be increased, as well as attorneys’ fees 
ordered paid, if infringement is found to be willful), or that we will be required to obtain a license from the other 
party in order to continue to commercialize the affected products, or to design our products in a manner that does not 
infringe a valid patent. We may not prevail in any legal action, and a required license under the patent may not be 
available on acceptable terms or at all, requiring cessation of activities that were found to infringe a valid patent. We 
also may not be able to develop a non-infringing product design on commercially reasonable terms, or at all.  

     Although we own a number of domestic and foreign patents and patent applications relating to AFRESA and 
cancer vaccine products under development, we have identified certain third-party patents having claims relating to 
pulmonary insulin delivery that may trigger an allegation of infringement upon the commercial manufacture and sale 
of AFRESA. We have also identified third-party patents disclosing methods of use and compositions of matter 
related to DNA-based vaccines that also may trigger an allegation of infringement upon the commercial manufacture 
and sale of our cancer therapy. If a court were to determine that our insulin products or cancer therapies were 
infringing any of these patent rights, we would have to establish with the court that these patents were invalid or 
unenforceable in order to avoid legal liability for infringement of these patents. However, proving patent invalidity or 
unenforceability can be difficult because issued patents are presumed valid. Therefore, in the event that we are 
unable to prevail in an infringement or invalidity action we will have to either acquire the third-party patents outright 
or seek a royalty-bearing license. Royalty-bearing licenses effectively increase production costs and therefore may 
materially affect product profitability. Furthermore, should the patent holder refuse to either assign or license us the 
infringed patents, it may be necessary to cease manufacturing the product entirely and/or design around the patents, if 
possible. In either event, our business would be harmed and our profitability could be materially adversely impacted. 

     Furthermore, because of the substantial amount of discovery required in connection with intellectual property 
litigation, there is a risk that some of our confidential information could be compromised by disclosure during this 
type of litigation. In addition, during the course of this kind of litigation, there could be public announcements of the 
results of hearings, motions or other interim proceedings or developments. If securities analysts or investors perceive 
these results to be negative, the market price of our common stock may decline.  

     In addition, patent litigation may divert the attention of key personnel and we may not have sufficient resources to 
bring these actions to a successful conclusion. At the same time, some of our competitors may be able to sustain the 
costs of complex patent litigation more effectively than we can because they have substantially greater resources. An 
adverse determination in a judicial or administrative proceeding or failure to obtain necessary licenses could prevent 
us from manufacturing and selling our products or result in substantial monetary damages, which would adversely 
affect our business and results of operations and cause the market price of our common stock to decline.  

We may not obtain trademark registrations for our potential trade names.  

     We have not selected trade names for some of our products and product candidates; therefore, we have not filed 
trademark registrations for our potential trade names for our products in all jurisdictions, nor can we assure that we 
will be granted registration of those potential trade names for which we have filed. Although we intend to defend any 
opposition to our trademark registrations, no assurance can be given that any of our trademarks will be registered in 
the United States or elsewhere or that the use of any of our trademarks will confer a competitive advantage in the 
marketplace. Furthermore, even if we are successful in our trademark registrations, the FDA has its own process for 
drug nomenclature and its own views concerning appropriate proprietary names. It also has the power, even after 
granting market approval, to request a company to reconsider the name for a product because of evidence of  

34

                                   
Table of Contents 

confusion in the marketplace. We cannot assure you that the FDA or any other regulatory authority will approve of 
any of our trademarks or will not request reconsideration of one of our trademarks at some time in the future.  

RISKS RELATED TO OUR COMMON STOCK  

Our stock price is volatile.  

     The current turbulence in the U.S. and global financial markets could adversely affect our stock price and our 
ability to raise additional capital through the sale of equity and/or debt securities. The stock market, particularly in 
recent years, has experienced significant volatility particularly with respect to pharmaceutical and biotechnology 
stocks, and this trend may continue. The volatility of pharmaceutical and biotechnology stocks often does not relate 
to the operating performance of the companies represented by the stock. Our business and the market price of our 
common stock may be influenced by a large variety of factors, including:  

(cid:129)   the progress and results of our clinical trials;

(cid:129)   general economic, political or stock market conditions;

(cid:129)   announcements by us or our competitors concerning clinical trial results, acquisitions, strategic alliances, 

technological innovations, newly approved commercial products, product discontinuations, or other 
developments;

(cid:129)   the availability of critical materials used in developing and manufacturing AFRESA or other product candidates;

(cid:129)   developments or disputes concerning our patents or proprietary rights;

(cid:129)   the expense and time associated with, and the extent of our ultimate success in, securing regulatory approvals;

(cid:129)   announcements by us concerning our financial condition or operating performance;

(cid:129)   changes in securities analysts’ estimates of our financial condition or operating performance;

(cid:129)   general market conditions and fluctuations for emerging growth and pharmaceutical market sectors;

(cid:129)   sales of large blocks of our common stock, including sales by our executive officers, directors and significant 

stockholders; and

(cid:129)   discussion of AFRESA, our other product candidates, competitors’ products, or our stock price by the financial 

and scientific press, the healthcare community and online investor communities such as chat rooms.

     Any of these risks, as well as other factors, could cause the market price of our common stock to decline.  

If other biotechnology and biopharmaceutical companies or the securities markets in general encounter 
problems, the market price of our common stock could be adversely affected.  

     Public companies in general and companies included on the Nasdaq Stock Market in particular have experienced 
extreme price and volume fluctuations that have often been unrelated or disproportionate to the operating 
performance of those companies. There has been particular volatility in the market prices of securities of 
biotechnology and other life sciences companies, and the market prices of these companies have often fluctuated 
because of problems or successes in a given market segment or because investor interest has shifted to other 
segments. These broad market and industry factors may cause the market price of our common stock to decline, 
regardless of our operating performance. We have no control over this volatility and can only focus our efforts on our 
own operations, and even these may be affected due to the state of the capital markets.  

     In the past, following periods of large price declines in the public market price of a company’s securities, 
securities class action litigation has often been initiated against that company. Litigation of this type could result in 
substantial costs and diversion of management’s attention and resources, which would hurt our business. Any 
adverse determination in litigation could also subject us to significant liabilities.

Our Chief Executive Officer and principal stockholder can individually control our direction and policies, and 
his interests may be adverse to the interests of our other stockholders. After his death, his stock will be left to his 
funding foundations for distribution to various charities, and we cannot assure you of the manner in which those 
entities will manage their holdings.  

     At January 31, 2009, Mr. Mann beneficially owned approximately 47.5% of our outstanding shares of capital 
stock. We believe members of Mr. Mann’s family beneficially owned at least an additional 1% of our outstanding 
shares of common stock, although Mr. Mann does not have voting or investment power with respect to these shares. 
By virtue of his holdings, Mr. Mann can and will continue to be able to effectively control the election of the 
members of our board of directors, our management and our affairs and prevent corporate transactions such as 
mergers, consolidations or the sale of all or substantially all of our assets that may be favorable from our standpoint 
or that of our other stockholders or cause a transaction that we or our other stockholders may view as unfavorable.  

     Subject to compliance with United States federal and state securities laws, Mr. Mann is free to sell the shares of 
our stock he holds at any time. Upon his death, we have been advised by Mr. Mann that his shares of our capital 
stock will be left to the Alfred E. Mann Medical Research Organization, or AEMMRO, and AEM Foundation for 
Biomedical Engineering, or AEMFBE, not-for-profit medical research foundations that serve as funding 
organizations for Mr. Mann’s various charities, including the Alfred Mann Foundation, or AMF, and the Alfred 
Mann Institute at the University of Southern California, the Technion-Israel Institute of Technology, and at Purdue 
University, and that may serve as funding organizations for any other charities that he may establish. The AEMMRO 
is a membership foundation consisting of six members, including Mr. Mann, his wife, three of his children and 
Dr. Joseph Schulman, the chief scientist of the AEMFBE. The AEMFBE is a membership foundation consisting of 
five members, including Mr. Mann, his wife, and the same three of his children. Although we understand that the 
members of AEMMRO and AEMFBE have been advised of Mr. Mann’s objectives for these foundations, once 
Mr. Mann’s shares of our capital stock become the property of the foundations, we cannot assure you as to how those 
shares will be distributed or how they will be voted.  

The future sale of our common stock or the conversion of our senior convertible notes into common stock could 
negatively affect our stock price.  

     Substantially all of the outstanding shares of our common stock are available for public sale, subject in some cases 
to volume and other limitations or delivery of a prospectus. If our common stockholders sell substantial amounts of 
common stock in the public market, or the market perceives that such sales may occur, the market price of our 
common stock may decline. Likewise the issuance of additional shares of our common stock upon the conversion of 
some or all of our senior convertible notes could adversely affect the trading price of our common stock. In addition, 
the existence of these notes may encourage short selling of our common stock by market participants. Furthermore, if 
we were to include in a company-initiated registration statement shares held by our stockholders pursuant to the 
exercise of their registrations rights, the sale of those shares could impair our ability to raise needed capital by 
depressing the price at which we could sell our common stock.  

     In addition, we will need to raise substantial additional capital in the future to fund our operations. If we raise 
additional funds by issuing equity securities or additional convertible debt, the market price of our common stock 
may decline and our existing stockholders may experience significant dilution.  

Anti-takeover provisions in our charter documents and under Delaware law could make an acquisition of us, 
which may be beneficial to our stockholders, more difficult and may prevent attempts by our stockholders to 
replace or remove our current management.  

     We are incorporated in Delaware. Certain anti-takeover provisions under Delaware law and in our certificate of 
incorporation and amended and restated bylaws, as currently in effect, may make a change of control of our company 
more difficult, even if a change in control would be beneficial to our stockholders. Our anti-takeover provisions 
include provisions such as a prohibition on stockholder actions by written consent, the authority of our board of 
directors to issue preferred stock without stockholder approval, and supermajority voting requirements for specified 
actions. In addition, we are governed by the provisions of Section 203 of the Delaware General Corporation Law, 
which generally prohibits stockholders owning 15% or more of our outstanding voting stock from merging or 
combining with us in certain circumstances. These provisions may delay or prevent an acquisition of us, even if the 
acquisition may be considered beneficial by some of our stockholders. In addition, they may frustrate or prevent any 
attempts by our stockholders to replace or remove our current management by making it more difficult for 
stockholders to replace members of our board of directors, which is responsible for appointing the members of our 
management.

Because we do not expect to pay dividends in the foreseeable future, you must rely on stock appreciation for any 
return on your investment.  

     We have paid no cash dividends on any of our capital stock to date, and we currently intend to retain our future 
earnings, if any, to fund the development and growth of our business. As a result, we do not expect to pay any cash 
dividends in the foreseeable future, and payment of cash dividends, if any, will also depend on our financial 
condition, results of operations, capital requirements and other factors and will be at the discretion of our board of 
directors. Furthermore, we may in the future become subject to contractual restrictions on, or prohibitions against, the 
payment of dividends. Accordingly, the success of your investment in our common stock will likely depend entirely 
upon any future appreciation. There is no guarantee that our common stock will appreciate in value after the offering 
or even maintain the price at which you purchased your shares, and you may not realize a return on your investment 
in our common stock.  

Item 1B. Unresolved Staff Comments.

Item 2. Properties  

     In 2001, we acquired a facility in Danbury, Connecticut that included two buildings comprising approximately 
190,000 square feet encompassing 17.5 acres. In September 2008, we completed the construction of approximately 
140,000 square feet of new manufacturing space providing us with two buildings totaling approximately 328,000 
square feet, housing our research and development, administrative and manufacturing functions, primarily for 
AFRESA, filling and packaging. We believe the Danbury facility will have sufficient space to satisfy potential 
commercial demand for the launch of AFRESA and, with the expansion completed, the first few years thereafter for 
AFRESA and other AFRESA-related products.  

     We own and occupy approximately 147,000 square feet of laboratory, office and manufacturing space in 
Valencia, California. The facility contains our principal executive offices and houses our research and development 
laboratories for our cancer and other programs. We also use this facility to provide support for the development of 
our AFRESA programs.  

     We lease approximately 59,000 square feet of office space in Paramus, New Jersey pursuant to a lease that ends in 
May 2010, with an option to extend the lease through May 2012.

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

     The following discussion of our financial condition and results of operations should be read in conjunction with 
our consolidated financial statements and notes thereto included in this Annual Report on Form 10-K.  

OVERVIEW  

     We are a biopharmaceutical company focused on the discovery, development and commercialization of 
therapeutic products for diseases such as diabetes and cancer. Our lead product candidate, AFRESA, is an ultra rapid-
acting insulin that has completed Phase 3

clinical trials evaluating its safety and efficacy in the treatment of diabetes. We believe that the performance 
characteristics, unique kinetics, convenience and ease of use of AFRESA may have the potential to change the way 
diabetes is treated.  

     We are a development stage enterprise and have incurred significant losses since our inception in 1991. As of 
December 31, 2008, we have incurred a cumulative net loss of $1.4 billion. To date, we have not generated any 
product revenues and have funded our operations primarily through the sale of equity securities. As discussed below 
in “Liquidity and Capital Resources”, if we are unable to obtain additional funding, there will be substantial doubt 
about our ability to continue as a going concern.  

     We do not expect to record sales of any product prior to regulatory approval and commercialization of AFRESA. 
We currently do not have the required approvals to market any of our product candidates, and we may not receive 
such approvals. We may not be profitable even if we succeed in commercializing any of our product candidates. We 
expect to make substantial expenditures and to incur additional operating losses for at least the next several years as 
we:  

(cid:129)   continue the clinical development of AFRESA for the treatment of diabetes;

(cid:129)   expand our manufacturing operations for AFRESA to meet our currently anticipated commercial production 

needs;

(cid:129)   expand our other research, discovery and development programs;

(cid:129)   expand our proprietary Technosphere platform technology and develop additional applications for the 

pulmonary delivery of other drugs; and

(cid:129)   enter into sales and marketing collaborations with other companies, if available on commercially reasonable 

terms, or develop these capabilities ourselves.

     Our business is subject to significant risks, including but not limited to the risks inherent in our ongoing clinical 
trials and the regulatory approval process, the results of our research and development efforts, competition from other 
products and technologies and uncertainties associated with obtaining and enforcing patent rights.  

RESEARCH AND DEVELOPMENT EXPENSES  

     Our research and development expenses consist mainly of costs associated with the clinical trials of our product 
candidates that have not yet received regulatory approval for marketing and for which no alternative future use has 
been identified. This includes the salaries, benefits and stock-based compensation of research and development 
personnel, raw materials, such as insulin purchases, laboratory supplies and materials, facility costs, costs for 
consultants and related contract research, licensing fees, and depreciation of laboratory equipment. We track research 
and development costs by the type of cost incurred. We partially offset research and development expenses with the 
recognition of estimated amounts receivable from the State of Connecticut pursuant to a program under which we 
can exchange qualified research and development income tax credits for cash. Included in research and development 
expenses for the year ended December 31, 2008 were purchases of insulin totaling $10.7 million and precursor raw 
material of $12.5 million.  

     Our research and development staff conducts our internal research and development activities, which include 
research, product development, clinical development, manufacturing and related activities. This staff is located in our 
facilities in Valencia, California; Paramus, New Jersey; and Danbury, Connecticut. We expense the majority of 
research and development costs as we incur them.  

     Clinical development timelines, likelihood of success and total costs vary widely. We are focused primarily on 
advancing AFRESA through regulatory filings. Based on the results of preclinical studies, we plan to develop 
additional applications of our Technosphere technology. Additionally, we anticipate that we will continue to 
determine which research and development projects to pursue, and how much funding to direct to each project, on an 
ongoing basis, in response to the scientific and clinical success of each product candidate. We cannot be certain when 
any revenues from the commercialization of our products will commence.  

     At this time, due to the risks inherent in the clinical trial process and given the early stage of development of our 
product candidates other than AFRESA, we are unable to estimate with any certainty the costs that we will incur in 
the continued development of our product candidates for commercialization. The costs required to complete the 
development of AFRESA will be largely dependent the cost and efficiency of our manufacturing process and 
discussions with the FDA on its requirements.

GENERAL AND ADMINISTRATIVE EXPENSES  

     Our general and administrative expenses consist primarily of salaries, benefits and stock-based compensation for 
administrative, finance, business development, human resources, legal and information systems support personnel. In 
addition, general and administrative expenses include professional service fees and business insurance costs.  

CRITICAL ACCOUNTING POLICIES  

     We have based our discussion and analysis of our financial condition and results of operations on our financial 
statements, which have been prepared in accordance with accounting principles generally accepted in the United 
States. The preparation of these financial statements requires us to make estimates and judgments that affect the 
reported amounts of assets, liabilities and expenses. We evaluate our estimates and judgments on an ongoing basis. 
We base our estimates on historical experience and on various assumptions that we believe to be reasonable under 
the circumstances, the results of which form the basis for making estimates of expenses such as stock option 
expenses and judgments about the carrying values of assets and liabilities. Actual results may differ from these 
estimates under different assumptions or conditions. The significant accounting policies that are critical to the 
judgments and estimates used in the preparation of our financial statements are described in more detail below.  

Impairment of long-lived assets  

     Assessing long-lived assets for impairment requires us to make assumptions and judgments regarding the carrying 
value of these assets. We evaluate long-lived assets for impairment whenever events or changes in circumstances 
indicate that the carrying value of an asset may not be recoverable. The assets are considered to be impaired if we 
determine that the carrying value may not be recoverable based upon our assessment of the following events or 
changes in circumstances:  

(cid:129)   significant changes in our strategic business objectives and utilization of the assets;

(cid:129)   a determination that the carrying value of such assets cannot be recovered through undiscounted cash flows;

(cid:129)   loss of legal ownership or title to the assets; or

(cid:129)   the impact of significant negative industry or economic trends.

     If we believe our assets to be impaired, the impairment we recognize is the amount by which the carrying value of 
the assets exceeds the fair value of the assets. Any write-downs would be treated as permanent reductions in the 
carrying amount of the asset and an operating loss would be recognized. In addition, we base the useful lives and 
related amortization or depreciation expense on our estimate of the useful lives of the assets. If a change were to 
occur in any of the above-mentioned factors or estimates, our reported results could materially change.  

To date, we have had recurring operating losses, and the recoverability of our long-lived assets is contingent upon 
executing our business plan. If we are unable to execute our business plan, we may be required to write down the 
value of our long-lived assets in future periods.  

Clinical trial expenses  

     Our clinical trial accrual process seeks to account for expenses resulting from our obligations under contract with 
vendors, consultants, and clinical site agreements in connection with conducting clinical trials. The financial terms of 
these contracts are subject to negotiations which vary from contract to contract and may result in payment flows that 
do not match the periods over which materials or services are provided to us under such contracts. Our objective is to 
reflect the appropriate trial expenses in our financial statements by matching period expenses with period services 
and efforts expended. We account for these expenses according to the progress of the trial as measured by patient 
progression and the timing of various aspects of the trial. We determine accrual estimates through discussions with 
internal clinical personnel and outside service providers as to the progress or state of completion of trials, or the 
services completed. Service provider status is then compared to the contractual obligated fee to be paid for such 
services. During the course of a clinical trial, we adjust our rate of clinical expense recognition if actual results differ 
from our estimates. In the event that we do not identify certain costs that have begun to be incurred or we 
underestimate or overestimate the level of services performed or the costs of such services, our reported expenses for 
a period would be too low or too high. The date on which certain services commence, the level of services performed 
on or before a given date and the cost of the services are often judgmental. We make these judgments based upon the 
facts and circumstances known to us in accordance with generally accepted accounting principles.

Stock-based compensation  

     On January 1, 2006, the Company adopted the provisions of FASB Statement No. 123R, which is a revision of 
FASB Statement No. 123, Accounting for Stock-Based Compensation (“FASB Statement No. 123”). Prior to 
January 1, 2006, the Company accounted for employee stock options and the employee stock purchase plan using the 
intrinsic value method in accordance with Accounting Principles Board (“APB”) Opinion No. 25 (“APB No. 25”), 
Accounting for Stock Issued to Employees, and adopted the disclosure only alternative of FASB Statement No. 123. 
FASB Statement No. 123R eliminated the intrinsic value method of accounting for stock options which the Company 
followed until December 31, 2005. Further, FASB Statement No. 123R requires all share-based payments to 
employees, including grants of stock options and the compensatory elements of employee stock purchase plans, to be 
recognized in the income statement based upon the fair value of the awards at the grant date.  

     Upon adoption of FASB Statement No. 123R, the Company selected the modified prospective transition method 
whereby unvested awards at the date of adoption, as well as awards that are granted, modified or settled after the date 
of adoption, will be measured and accounted for in accordance with FASB Statement No. 123R. Measurement and 
attribution of compensation cost for awards unvested as of January 1, 2006 is based on the same estimate of the 
grant-date or modification-date fair value and the same attribution method (straight-line) used previously under 
FASB Statement No. 123. Our consolidated financial statements as of and for the years ended December 31, 2008 
and 2007 reflect the impact of FASB Statement No. 123R. In accordance with the modified prospective transition 
method, our consolidated financial statements for prior periods have not been restated to reflect, and do not include, 
the impact of FASB Statement 123R.  

Accounting for income taxes  

     We must make management judgments when determining our provision for income taxes, our deferred tax assets 
and liabilities and any valuation allowance recorded against our net deferred tax assets. At December 31, 2008, we 
have established a valuation allowance of $525.6 million against all of our net deferred tax asset balance, due to 
uncertainties related to our deferred tax assets as a result of our history of operating losses. The valuation allowance 
is based on our estimates of taxable income by jurisdiction in which we operate and the period over which our 
deferred tax assets will be recoverable. In the event that actual results differ from these estimates or we adjust these 
estimates in future periods, we may need to change the valuation allowance, which could materially impact our 
financial position and results of operations.  

     In July 2006, the FASB issued FASB Interpretation No. 48, Accounting for Uncertainty in Income Taxes — an 
interpretation of FASB Statement No. 109 (“FIN 48”), which clarifies the accounting and disclosure for uncertainty 
in tax positions, as defined. FIN 48 seeks to reduce the diversity in practice associated with certain aspects of the 
recognition and measurement related to accounting for income taxes. We are subject to the provisions of FIN 48 as of 
January 1, 2007. We believe that our income tax filing positions and deductions will be sustained on audit and do not 
anticipate any adjustments that will result in a material change to our financial position. Therefore, no reserves for 
uncertain income tax positions have been recorded pursuant to FIN 48. The cumulative effect, if any, of applying 
FIN 48 is to be reported as an adjustment to the opening balance of retained earnings in the year of adoption. Our 
adoption of FIN 48 did not result in a cumulative effect adjustment to retained earnings. Tax years since 1992 remain 
subject to examination by the major tax jurisdictions in which we are subject to tax.

     The decrease in research and development expenses for the year ended December 31, 2008, as compared to the 
year ended December 31, 2007, was primarily due to decreased costs associated with the clinical development of 
AFRESA as we completed our pivotal AFRESA trials during 2008, offset by increases in manufacturing costs 
associated with preparations for commercial scale manufacturing of AFRESA, including the expansion, qualification 
and validation of our commercial manufacturing processes and facilities. We anticipate that our research and 
development expenses will decrease in 2009 as we completed our pivotal AFRESA clinical trials and the expansion 
of our commercial manufacturing facilities during 2008.  

     The research and development tax credit recognized for the years ended December 31, 2008 and 2007 partially 
offsets our research and development expenses. The State of Connecticut provides an opportunity to exchange certain 
research and development income tax credit carryforwards for cash in exchange for forgoing the carryforward of the 
research and development credits. Estimated amounts receivable under the program are recorded as a reduction of 
research and development expenses. During the years ended December 31, 2008 and 2007, research and development 
expenses were offset by $1.8 million and $0.8 million, respectively, in connection with the program.

     The increase in general and administrative expenses for the year ended December 31, 2008, as compared to the 
year ended December 31, 2007, was primarily due to increased salary-related expenses and consulting fees. We 
expect general and administrative expenses to decrease slightly in 2009 as a result of decreased salary-related 
expenses and consulting fees.  

Interest Income and Expense  

     Interest income for the year ended December 31, 2008 decreased $12.6 million as compared to the year ended 
December 31, 2007 primarily due to lower cash balances as the company used cash to fund operating and capital 
expenditures. Interest expense for the year ended December 31, 2007 was related to the convertible notes issued in 
December 2006 and amortization of the debt issuance costs, partially offset by capitalized interest related to 
construction in progress. Interest expense for the year ended December 31, 2008 also included interest related to 
amounts borrowed under the loan agreement with our principal stockholder in December 2008.

     The increase in research and development expenses for the year ended December 31, 2007, as compared to the 
year ended December 31, 2006, was primarily due to increases in manufacturing costs, including clinical supplies, 
for Technosphere Insulin and increased costs associated with the expanded clinical development of AFRESA and the 
continuation of other preclinical studies.  

     The research and development tax credit recognized for the years ended December 31, 2007 and 2006 partially

LIQUIDITY AND CAPITAL RESOURCES  

     We have funded our operations primarily through the sale of equity securities. In October 2007, we issued and 
sold a total of 27,014,686 shares of our common stock. Of this total, 15,940,489 shares were sold to our principal 
stockholder at a price per share of $9.41 and 11,074,197 shares were sold to other investors at a price per share of 
$9.03. The resulting aggregate net proceeds were approximately $249.8 million after expenses. In December 2006, 
we issued and sold 23,000,000 shares of our common stock at a price of $17.42 per share in an underwritten public 
offering. The resulting aggregate net proceeds to us from this common stock offering were approximately $384.7 
million after expenses. In December 2006, we also sold $115.0 million aggregate principal amount of 3.75% Senior 
Convertible Notes due 2013. The resulting aggregate net proceeds to us from this note offering were approximately 
$111.3 million after expenses.  

     In August 2006, we entered into a $150.0 million loan arrangement with our principal stockholder, which was 
amended on August 1, 2007 and replaced with a new loan arrangement on October 2, 2007 allowing us to borrow up 
to a total of $350.0 million before January 1, 2010. On February 26, 2009, as a result of our principal stockholder 
being licensed as a finance lender under the California Finance Lenders Law, the promissory note underlying the 
loan arrangement was revised to reflect the lender as The Mann Group LLC, or the Lender, an entity controlled by 
our principal stockholder. This new license also eliminated the draw restrictions under the previous loan arrangement 
and we are now able to borrow up to a total of $350.0 million from time to time with appropriate notice to the 
Lender. Interest will accrue on each outstanding advance at a fixed rate equal to the one-year LIBOR rate as reported 
by the Wall Street Journal on the date of such advance plus 3% per annum and will be payable quarterly in arrears. 
Principal repayment is due on December 31, 2011. At any time after January 1, 2010, our Lender can require us to 
prepay up to $200.0 million in advances that have been outstanding for at least 12 months. If our Lender exercises 
this right, we will have until the earlier of 180 days after our Lender provides written notice or December 31, 2011 to 
prepay such advances. In the event of a default, all unpaid principal and interest either becomes immediately due and 
payable or may be accelerated at our Lender’s option, and the interest rate will increase to the one-year LIBOR rate 
calculated on the date of the initial advance or in effect on the date of default, whichever is greater, plus 5% per 
annum. Any borrowings under the loan arrangement will be unsecured. The loan arrangement contains no financial 
covenants. There are no warrants associated with the loan arrangement, nor are advances convertible into our 
common stock. As of December 31, 2008, the amount outstanding under the arrangement was $30.0 million.  

     During the year ended December 31, 2008, we used $271.3 million of cash for our operations compared to using 
$245.1 million for our operations in the year ended December 31, 2007. We had a net loss of $303.0 million for the 
year ended December 31, 2008, of which $37.1 million consisted of non-cash charges such as depreciation and 
amortization, stock-based compensation, and other stock-based charges pursuant to a research agreement. We expect 
our negative operating cash flow to continue at least until we obtain regulatory approval and achieve 
commercialization of AFRESA.  

     We spent $99.9 million of cash for investing activities during the year ended December 31, 2008, compared to 
generating $38.7 million for the year ended December 31, 2007. For the year ended December 31, 2008, cash used 
by investing activities was primarily for $82.5 million in machinery and equipment purchases, mainly used to expand 
our manufacturing operations, and net purchases of marketable securities of $17.6 million. Cash provided by 
investing activities in 2007 was primarily from net sales of marketable securities of $116.9 million partially offset by 
$78.3 million in machinery and equipment purchases.  

     Our financing activities provided cash of $30.6 million for the year ended December 31, 2008 compared to 
$255.2 million for 2007. For 2008, cash from financing activities was primarily from the related party borrowings 
received in December 2008, as well as the exercise of stock awards. Cash from financing activities in 2007 was 
primarily from the equity offering in October 2007 and the exercise of stock options throughout the year.  

     As of December 31, 2008, we had $27.6 million in cash and cash equivalents. Although we believe our existing 
cash resources, including the $320.0 million of available borrowing under the loan arrangement with our principal 
stockholder, will be sufficient to fund our anticipated cash requirements through the first quarter of 2010, we will 
require significant additional financing in the future to fund our operations and if we are unable to do so, there will be 
substantial doubt about our ability to continue as a going concern. Accordingly, we expect that we will need to raise 
additional capital, either through the sale of equity and/or debt securities, a strategic business collaboration with a 
pharmaceutical or biotechnology company or the establishment of other funding facilities, in order to continue the 
development and commercialization of AFRESA and other product candidates and to support our other ongoing 
activities.  

     We intend to use our capital resources to continue the development and commercialization, if approved, of 
AFRESA and to develop additional applications for our proprietary Technosphere platform technology. In addition, 
portions of our capital resources will be devoted to expanding our other product development programs for the 
treatment of different types of cancers. We are expending a portion of our capital to scale up our manufacturing 
capabilities in our Danbury facilities. We also intend to use our capital resources for general corporate purposes, 
which may include in-licensing or acquiring additional technologies.

Table of Contents 

     We have held extensive discussions with a number of pharmaceutical companies concerning a potential strategic 
business collaboration for AFRESA. To date, we have not reached agreement with any of these companies on a 
collaboration. While we are continuing to engage in such discussions, we believe that we will have to expend 
significant additional time and effort before we could reach agreement, and we cannot predict when, if ever, we 
could conclude such an agreement with a partner. There can be no assurance that any such collaboration will be 
available to us on a timely basis or on acceptable terms, if at all.  

     If we enter into a strategic business collaboration with a pharmaceutical or biotechnology company, we would 
expect, as part of the transaction, to receive additional capital. In addition, we expect to pursue the sale of equity 
and/or debt securities, or the establishment of other funding facilities. Issuances of debt or additional equity could 
impact the rights of our existing stockholders, dilute the ownership percentages of our existing stockholders and may 
impose restrictions on our operations. These restrictions could include limitations on additional borrowing, specific 
restrictions on the use of our assets as well as prohibitions on our ability to create liens, pay dividends, redeem our 
stock or make investments. We also may seek to raise additional capital by pursuing opportunities for the licensing, 
sale or divestiture of certain intellectual property and other assets, including our Technosphere technology platform. 
There can be no assurance, however, that any strategic collaboration, sale of securities or sale or license of assets will 
be available to us on a timely basis or on acceptable terms, if at all. If we are unable to raise additional capital, we 
may be required to enter into agreements with third parties to develop or commercialize products or technologies that 
we otherwise would have sought to develop independently, and any such agreements may not be on terms as 
commercially favorable to us.  

     However, we cannot provide assurances that our plans will not change or that changed circumstances will not 
result in the depletion of our capital resources more rapidly than we currently anticipate. If planned operating results 
are not achieved or we are not successful in raising additional equity financing or entering a business collaboration, 
we may be required to reduce expenses through the delay, reduction or curtailment of our projects, including 
AFRESA development activities, or further reduction of costs for facilities and administration, and there will be 
substantial doubt about our ability to continue as a going concern.  

Off-Balance Sheet Arrangements  

     As of December 31, 2008, we did not have any off-balance sheet arrangements.  

COMMITMENTS AND CONTINGENCIES  

     Our contractual obligations represent future cash commitments and liabilities under agreements with third parties, 
and exclude contingent liabilities for which we cannot reasonably predict future payments. Accordingly, the table 
below excludes contractual obligations relating to milestone and royalty payments due to third parties, all of which 
are contingent upon certain future events. The expected timing of payment of the obligations presented below is 
estimated based on current information. Future payments relate to operating lease obligations (including facility 
leases executed in March 2005 and November 2005), the senior convertible notes, and open purchase order and 
supply commitments consisted of the following at December 31, 2008 (in thousands):

RELATED PARTY TRANSACTIONS  

     For a description of our related party transactions see Note 15 — Related Party Transactions in the notes to our 
financial statements.  

RECENT ACCOUNTING PRONOUNCEMENTS  

     In December 2007, the FASB ratified the EITF consensus on EITF Issue No. 07-1, Accounting for Collaborative 
Arrangements, that discusses how parties to a collaborative arrangement (which does not establish a legal entity 
within such arrangement) should account for various activities. The consensus indicates that costs incurred and 
revenues generated from transactions with third parties (i.e. parties outside of the collaborative arrangement) should 
be reported by the collaborators on the respective line items in their income statements pursuant to EITF Issue 
No. 99-19, Reporting Revenue Gross as a Principal Versus Net as an Agent., Additionally, the consensus provides 
that income statement characterization of payments between the participants in a collaborative arrangement should be 
based upon existing authoritative pronouncements; analogy to such pronouncements if not within their scope; or a 
reasonable, rational, and consistently applied accounting policy election. EITF Issue No. 07-1 is effective beginning 
January 1, 2009 and is to be applied retrospectively to all periods presented for collaborative arrangements existing 
as of the date of adoption. We believe that the adoption of EITF No. 07-1 will not have a material effect on our 
results of operations, financial position, or cash flows.  

     In December 2007, the FASB issued FASB Statement No. 141(R), “Business Combinations” and FASB 
Statement No. 160, “Accounting and Reporting of Noncontrolling Interests in Consolidated Financial Statements — 
an amendment of ARB No. 51” (“FASB Statement No. 160”). These standards will significantly change the 
accounting and reporting for business combination transactions and noncontrolling (minority) interests in 
consolidated financial statements, including capitalizing at the acquisition date the fair value of acquired IPR&D, and 
remeasuring and writing down these assets, if necessary, in subsequent periods during their development. These new 
standards will be applied prospectively for business combinations that occur on or after January 1, 2009, except that 
presentation and disclosure requirements of FASB Statement No. 160 regarding noncontrolling interests shall be 
applied retrospectively. Adoption of these statements are expected to have a significant effect on how acquisition 
transactions, subsequent to January 1, 2009, are reflected in the financial statements.  

     As of January 1, 2008, we adopted on a prospective basis certain required provisions of FASB Statement No. 157, 
Fair Value Measurements (“FASB Statement No. 157”), as amended by FASB Financial Staff Position (“FSP”) 
No. 157-2. Those provisions relate to our financial assets and liabilities carried at fair value and its fair value 
disclosures related to financial assets and liabilities. FASB Statement 157 defines fair value, expands related 
disclosure requirements and specifies a hierarchy of valuation techniques based on the nature of the inputs used to 
develop the fair value measures. Fair value is defined as the price that would be received to sell an asset or paid to 
transfer a liability in an orderly transaction between market participants at the measurement date. There are three 
levels of inputs to fair value measurements — Level 1, meaning the use of quoted prices for identical instruments in 
active markets; Level 2, meaning the use of quoted prices for similar instruments in active markets or quoted prices 
for identical or similar instruments in markets that are not active or are directly or indirectly observable; and Level 3, 
meaning the use of unobservable inputs. Observable market data should be used when available. All of our 
marketable securities are classified as available-for-sale securities and are carried at fair value. Our valuation 
measurements for the available-for-sale securities are Level 2 measurements. The partial adoption of FASB 
Statement 157 did not have a significant impact on our results of operations, financial position or cash flows.  

     In May 2008, the FASB issued FSP No. APB 14-1 (“FSP No. APB 14-1”), “Accounting for Convertible Debt 
Instruments that may be Settled in Cash Upon Conversion (Including Partial Cash Settlement). ” FSP No. APB 14-1 
establishes that the liability and equity components of convertible debt instruments within the scope of FSP APB 
No. 14-1 shall be separately accounted for in a manner that will reflect the entity’s nonconvertible debt borrowing 
rate when interest cost is recognized in subsequent periods. The carrying amount of the liability component of the 
convertible debt instrument will be determined by measuring the fair value of a similar liability that does not have an 
associated equity component. The carrying value of the equity component will be determined by deducting the fair 
value of the liability component from the initial proceeds ascribed to the convertible debt instrument as a whole. 
Related transaction costs shall be allocated to the liability and equity components in proportion to the allocation of 
proceeds and accounted for as debt issuance costs and equity issuance costs, respectively. The excess of the principal 
amount of the liability component over its carrying amount shall be amortized to interest cost using the interest 
method. FSP No. APB 14-1 is effective beginning January 1, 2009 and shall be applied retrospectively to all periods 
presented with the cumulative effect of the change in accounting principle on periods prior to those presented

     In June 2008, the FASB issued EITF Issue 07-5 “Determining whether an Instrument (or Embedded Feature) is 
indexed to an Entity’s Own Stock” (“EITF No. 07-5”). Paragraph 11(a) of FASB Statement No. 133 “Accounting for 
Derivatives and Hedging Activities” specifies that a contract that would otherwise meet the definition of a derivative 
but is both (a) indexed to the Company’s own stock and (b) classified in stockholders’ equity in the statement of 
financial position would not be considered a derivative financial instrument. EITF No. 07-5 provides a new two-step 
model to be applied in determining whether a financial instrument or an embedded feature is indexed to an issuer’s 
own stock and thus able to qualify for the SFAS 133 paragraph 11(a) scope exception. EITF No. 07-5 is effective for 
financial statements issued for fiscal years beginning after December 31, 2005, and interim periods within those 
fiscal years. Early adoption is not permitted. We believe that the adoption of EITF No. 07-5 will not have a material 
effect on our results of operations, financial position, or cash flows.  

Item 7A. Quantitative and Qualitative Disclosures About Market Risk  

     We have not used derivative financial instruments in the past to hedge market risk. We are exposed to market risk 
related to changes in interest rates impacting our short-term investment portfolio as well as the interest rate on our 
credit facility with an entity controlled by our principal stockholder. The interest rate on our credit facility with our 
principal stockholder is a fixed rate equal to the one-year LIBOR rate as reported by the Wall Street Journal on the 
date of such advance plus 3% per annum. Our current policy requires us to maintain a highly liquid short-term 
investment portfolio consisting mainly of U.S. money market funds and investment-grade corporate, government and 
municipal debt. None of these investments is entered into for trading purposes. Our cash is deposited in and invested 
through highly rated financial institutions in North America. Our short-term investments at December 31, 2008 are 
comprised mainly of short term US treasury notes. If we were to draw the available amount on our $350 million 
credit facility and interest rates were to increase from levels at December 31, 2008 we could experience a higher 
level of interest expense than assumed in our current operating plan.

Item 9A. Controls and Procedures  

Conclusion Regarding the Effectiveness of Disclosure Controls and Procedures  

     We maintain disclosure controls and procedures that are designed to ensure that information required to be 
disclosed in our reports filed under the Exchange Act, is recorded, processed, summarized and reported within the 
time periods specified in the SEC’s rules and forms and that such information is accumulated and communicated to 
our management, including our chief executive officer and chief financial officer, as appropriate, to allow for timely 
decisions regarding required disclosure. In designing and evaluating the disclosure controls and procedures, 
management recognizes that any controls and procedures, no matter how well designed and operated, can provide 
only reasonable assurance of achieving the desired control objectives, and management is required to apply its 
judgment in evaluating the cost-benefit relationship of possible controls and procedures.  

     Our chief executive officer and chief financial officer performed an evaluation under the supervision and with the 
participation of our management, of our disclosure controls and procedures (as defined in Rule 13a-15(e) and 15d-15
(e)of the Exchange Act) as of December 31, 2008. Based on that evaluation, our chief executive officer and chief 
financial officer concluded that our disclosure controls and procedures were effective at the reasonable assurance 
level.  

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 Rule 13a-15(f). Under the supervision and with the participation 
of our management, including our chief executive officer and chief financial officer, we conducted an evaluation of 
the effectiveness of our internal control over financial reporting based on the framework set forth in Internal Control 
— Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. 
Based on our evaluation under the framework set forth in Internal Control — Integrated Framework, our 
management concluded that our internal control over financial reporting was effective as of December 31, 2008.

Report of Independent Registered Public Accounting Firm  

To the Board of Directors and Stockholders of MannKind Corporation 
Valencia, California  

     We have audited the internal control over financial reporting of MannKind Corporation (the “Company”) as of 
December 31, 2008, based on criteria established in Internal Control — Integrated Framework issued by the 
Committee of Sponsoring Organizations of the Treadway Commission. The Company’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 by, or under the supervision of, the 
company’s principal executive and principal financial officers, or persons performing similar functions, and effected 
by the company’s board of directors, management, and other personnel 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 the inherent limitations of internal control over financial reporting, including the possibility of 
collusion or improper management override of controls, material misstatements due to error or fraud may not be 
prevented or detected on a timely basis. Also, projections of any evaluation of the effectiveness of the internal control 
over financial reporting to future periods are subject to the risk that the 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, the Company maintained, in all material respects, effective internal control over financial 
reporting as of December 31, 2008, based on the criteria established in Internal Control — Integrated Framework 
issued by the Committee of Sponsoring Organizations of the Treadway Commission.  

     We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board 
(United States), the financial statements as of and for the year ended December 31, 2008 of the Company and our 
report dated February 27, 2009 expressed an unqualified opinion on those financial statements.

Table of Contents 

     We have appointed Mr. Consiglio as our “Audit Committee financial expert,” as that term is defined in applicable 
SEC rules. In making such determinations, the Board of Directors made a qualitative assessment of Mr. Consiglio’s 
level of knowledge and experience based on a number of factors, including his formal education and experience.  

CODE OF BUSINESS CONDUCT AND ETHICS  

     We have adopted a Code of Business Conduct and Ethics Policy that applies to our directors and employees 
(including our principal executive officer, principal financial officer, principal accounting officer and controller), and 
have posted the text of the policy on our website (www.mannkindcorp.com) in connection with “Investors” materials. 
In addition, we intend to promptly disclose on our website (i) the nature of any amendment to the policy that applies 
to our principal executive officer, principal financial officer, principal accounting officer or controller, or persons 
performing similar functions and (ii) the nature of any waiver, including an implicit waiver, from a provision of the 
policy that is granted to one of these specified individuals, the name of such person who is granted the waiver and the 
date of the waiver.  

SECTION 16(A) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE  

     Section 16(a) of the Exchange Act requires our directors, executive officers and any persons beneficially holding 
more than 10% of our common stock to report their initial ownership of our common stock and any subsequent 
changes in that ownership to the SEC. Our executive officers, directors and greater than 10% stockholders are 
required by SEC regulation to furnish us with copies of all Section 16(a) forms they file.  

     Specific due dates for these reports have been established and we are required to identify in this annual report 
those persons who failed to timely file these reports. To our knowledge, based solely on a review of the copies of 
such reports furnished to us and written representations that no other reports were required, during the fiscal year 
ended December 31, 2008, all of our directors, officers and greater than 10% stockholders complied with the Section 
16(a) filing requirements.  

Item 11. Executive Compensation  

COMPENSATION DISCUSSION AND ANALYSIS  

     We are pleased to present our report on executive compensation. The report’s objective is to assist our 
stockholders in understanding the objectives and procedures used by the Compensation Committee of our Board of 
Directors in establishing its recommendation to the Board of Directors regarding the compensation of our executive 
officers.  

     MannKind Corporation is a biopharmaceutical company focused on the discovery, development and 
commercialization of therapeutic products for diseases such as diabetes and cancer. Our compensation program is 
designed to attract and retain the individuals needed to support our business strategy and to allow us to compete 
effectively with pharmaceutical and biotechnology companies.  

     The Compensation Committee is responsible for establishing and administering our policies governing the 
compensation for our executive officers. The Compensation Committee is composed entirely of independent 
directors within the meaning of the applicable SEC and Nasdaq Stock Market rules. Hakan Edstrom, our President 
and Chief Operating Officer, is not a member of the Compensation Committee, but he regularly attends 
Compensation Committee meetings in order to provide valuable insight and guidance to the Compensation 
Committee. Similarly, Alfred Mann, our Chief Executive Officer and largest shareholder, is not a member of the 
Compensation Committee, but he periodically attends Compensation Committee meetings for the same purpose. The 
Compensation Committee responsibilities and duties are outlined in detail in the Compensation Committee charter, 
which is available on our website at www.mannkindcorp.com. A primary responsibility of the Compensation 
Committee is to make recommendations regarding the compensation for our executive officers, including the 
determination and confirmation of annual corporate goal achievement for purposes of awarding bonuses, to the full 
Board of Directors for its approval. The Compensation Committee engages outside consulting firms to assist in 
developing compensation levels and practices and to provide external market data. For certain compensation 
decisions made in 2008 and more recently, the Compensation Committee received support from Mercer Consulting.  

     The Compensation Committee meets outside the presence of all of our executive officers, including the named 
executive officers, in order to consider the appropriate compensation for our chief executive officer. For all other 
named executive officers, the Compensation Committee meets outside the presence of all executive officers except 
our chief executive officer. The annual performance reviews of our executive officers are considered by the 
Compensation Committee when making decisions regarding base salary, targets for and payments under our bonus 
plan and grants of equity incentive awards. When making recommendations regarding individual executive  

53  

                                   
Table of Contents 

officers, the Compensation Committee considers the importance of the position to us, the past salary history of the 
executive officer and the contributions we expect the executive officer to make to the success of our business.  

Compensation Philosophy And Objectives  

     The Compensation Committee oversees our executive compensation within the context of a compensation 
philosophy. This philosophy is to provide compensation and benefits programs designed to attract, motivate, and 
retain a high caliber workforce that enables us to compete with companies in the pharmaceutical and biotechnology 
industries and to reward individual and corporate performance.  

     We believe that a well-designed compensation program for our executive officers should:  

(cid:129)   align the goals of the executive officer with the goals of the stockholders;

(cid:129)   recognize individual initiative, effort and achievement;

(cid:129)   provide total compensation that enables us to compete with companies in the pharmaceutical and 

biotechnology industries; and

(cid:129)   align compensation with our short-term and long-term corporate objectives and strategy, focusing executive 

officer behavior on the fulfillment of those objectives.

     In keeping with this philosophy, our executive compensation program is designed to achieve the following 
objectives:  

(cid:129)   attract and retain talented and experienced executives;

(cid:129)   motivate and reward executives whose knowledge, skills and performance are critical to our success;

(cid:129)   retain executives and employees who are instrumental in accomplishing our corporate objectives;

(cid:129)   align the interests of our executives and stockholders by motivating executives to increase stockholder value 

and rewarding executives when stockholder value increases;

(cid:129)   provide a competitive compensation package which is weighted towards pay-for-performance, and in which 
total compensation is primarily determined by the company’s and the individual’s achievement of results;

(cid:129)   ensure fairness among the executive management team by recognizing the contributions each executive makes 

to our success;

(cid:129)   foster a shared commitment among executives by aligning the company’s and their individual goals; and

(cid:129)   compensate our executives to manage our business to meet our long-term objectives.

     We utilize the following principles to guide compensation decisions:  

Competitive Market Assessment:  

     The Compensation Committee regularly reviews competitive market data to determine if our compensation levels 
remain at targeted levels and our pay practices are appropriate. These assessments include a review of base salary, 
annual incentives, and long-term incentives. These components are evaluated against a group of peer companies as 
well as industry specific and general published survey compensation data. Specifically, we utilized the Radford 
Global Life Sciences Executive Survey, the SIRS Executive Compensation Survey and the Salary.com CompAnalyst 
Executive Survey. Since 2007, the Compensation Committee has engaged Mercer Consulting to benchmark the 
compensation levels of eight executive positions relative to a group of peer companies.  

     In addition to the elements described above, the Compensation Committee also considered the broader economic 
conditions currently affecting the United States and other major countries. In light of these circumstances, the 
Compensation Committee determined that it was appropriate to accept a recommendation from management that all 
2009 salaries and wages, including those of named executive officers, be held at 2008 levels.

Table of Contents 

Peer Group:  

     In the past, we have developed a peer group for benchmarking purposes, by considering companies in a similar 
industry and of a similar size in terms of revenue and number of employees. Typically, our peer group was selected 
to consist equally of (i) companies with zero revenue, (ii) companies with revenue between $0 and $1B and 
(iii) companies with revenue between $1 and $3B. All companies are either biotechnology or pharmaceutical 
companies. Companies were selected with various revenue sizes because we are recruiting from and competing for 
executive with companies that are generating revenue. For 2008, the primary peer group of companies for pay 
comparison purposes included:  

Atherogenics, Inc.  
Barr Pharmaceuticals, Inc.  
Biogen Idec, Inc.  
Biomarin Pharmaceutical, Inc.  
Cephalon, Inc.  
CV Therapeutics, Inc.  

Favrille Inc.
Genitope Corp.
Genzyme Corp.
Nektar Therapeutics
Tercica, Inc.
Theravance, Inc.

     In addition, we monitored the executive compensation for three additional companies with which we compete for 
executives. However, since these three companies have significantly larger revenue than us, they are not included in 
the peer group: Amgen Inc., Genentech Inc., and Schering-Plough Corporation.  

     In light of our decision to hold salaries and wages at 2008 levels, we have not updated the peer group for 2009.  

Market Positioning:  

     The Compensation Committee reviews executive compensation at least annually, establishes competitive 
compensation levels using competitive market data and designs the compensation program to provide pay 
commensurate with individual and corporate performance. We normally position total compensation levels for 
executives at the 60th percentile of our peer group; however, compensation may fall above or below this level under 
a range of circumstances, such as individual performance, tenure with the company or retention concerns. We 
supplement the peer group data with the survey data described above.  

     We believe our executive compensation packages are reasonable when considering our business strategy, the 
revenue potential of our business, our compensation philosophy and the competitive market pay data.  

     In addition to the factors listed above, we also consider, among other things:  

(cid:129)   our business need for the executive officer’s skills;

(cid:129)   the contributions that the executive officer has made or we believe will make to our success;

(cid:129)   the transferability of the executive officer’s managerial skills to other potential employers; and

(cid:129)   the relevance of the executive officer’s experience to other potential employers, particularly in the 

pharmaceutical and biotechnology industries

Pay-for-Performance:  

     Our executive compensation program emphasizes pay-for-performance. The compensation package for our 
executive officers includes both cash and equity incentive plans that align an executive’s compensation with our 
short-term and long-term performance goals and objectives.  

     The annual cash incentive awards under our bonus plan are intended to compensate our executive officers for 
achieving our annual goals at the corporate level and for achieving individual annual performance objectives. The 
goals for our company and individual measures are established so that target attainment is not assured. The 
attainment of payment for performance at or above target levels requires significant effort on the part of our 
executives. Long-term equity incentives are intended to reward executives for growth in shareholder value. 
Additional details of the plan are described below under “Bonus Plan” and “Long-Term Incentives”.

COMPENSATION COMPONENTS  

     In order to provide a total compensation package that is tied to shareholder value creation and the achievement of 
strategic corporate goals, our executive compensation package is comprised of several components. These 
components are designed to work together to create a balanced approach to compensation, rewarding both short-term 
and long-term performance and fostering sufficient retentive effect to secure the services of our executive officer 
while we execute on our plans. Currently, our compensation structure for executive officers includes a combination 
of base salary, bonus, stock options and restricted stock awards, 401(k), medical and other benefits, severance and 
change in control and other post termination provisions. Each component is described in further detail below.  

Base Salary  

     Base salaries are designed to provide compensation for day-to-day management of the Company assuming 
acceptable levels of performance. This component is designed to provide consistent and steady cash flow for the 
executive and represents only a portion of total compensation. Salary levels are based primarily upon the competitive 
market for the executive officers’ services as determined through comparisons with peer companies and survey data. 
Base salaries for our executives are intended to fall at the median of the competitive market. Individual performance, 
responsibility, and the importance of each role in our organization can also impact base salary levels.  

Bonus Plan  

     The annual cash incentive awards under our bonus plan are intended to compensate our executive officers for 
achieving our annual goals at the corporate level and for achieving individual annual performance objectives. For 
2008, the corporate goals were based on achievement of certain operational goals. Because we are still in the process 
of developing our proprietary products and have not yet brought any such products to market, the use of traditional 
performance standards, such as profit levels and return on equity, are not appropriate in our evaluation of executive 
officer performance.  

     Each eligible position, including the executive officers, is assigned a target bonus opportunity expressed as a 
percentage of base salary, which reflects market competitive levels. Target bonus opportunities are generally 
positioned at the 50th percentile of the market. For Mr. Mann, the target bonus opportunity for 2008 was 50% of base 
salary. The target bonuses for the other named executive officers for 2008 were as follows: Mr. Edstrom, 50%; 
Mr. Pfeffer, 35%; Dr. Richardson, 40%; and Dr. Martens, 35%. Payments of target bonuses are not guaranteed and 
are subject to funding and corporate and individual performance.  

     Our bonus plan was funded based on the achievement of overall corporate goals, based on a careful review by the 
Compensation Committee of the accomplishments of the Company during the previous year. For 2008, the annual 
incentive awards of our named executive officers were determined solely by performance against corporate 
objectives.  

     The corporate objectives for 2008, their relative weight and the achievement levels for each were as follows:  

Objective
Prepare a high quality NDA for AFRESA 
Determine the commercialization strategy for AFRESA
Complete the Danbury manufacturing facility 
Expand the Company’s pipeline of product opportunities

Weight  
 30%  
 40%  
 20%  
 10%  

Score
 100%
  95%
 150%
 125%

     As a result, the Compensation Committee determined that the Company achieved 110% of the corporate goals for 
2008. Accordingly, for 2008, each of the named executive officers will receive a bonus payment that represents 
110% of his target award.  

Long-Term Incentives  

     In order to provide a significant retention incentive and to ensure a strong link to the long-term interests of 
shareholders, we provide a portion of our total compensation in the form of equity compensation — specifically, 
stock options and restricted stock units. Executive officers, as well as all full-time employees, are eligible to receive 
awards at the discretion of the Compensation Committee. Equity awards are granted under the 2004 Equity Incentive 
Plan, or the Plan, which is administered by the Compensation Committee.  

     In 2007, we adopted annual and new hire equity grant guidelines that formed the baseline for the number of 
awards granted to each executive. In developing these guidelines, the Compensation Committee utilized published 
surveys and peer compensation information to determine an appropriate and competitive annual award value. This 
value also took into consideration historical grant practices, internal pay equity, and share dilution. The intended 
award value was then split between stock options and restricted stock units. The guidelines for executive officers 
seek to deliver approximately 75% of the award value in stock options and 25% of the award value in restricted stock 

56

                                   
 
 
 
 
 
 
 
 
 
 
Table of Contents 

units. We believe this mix of equity aligns with the interests of stockholders and encourages both stock price growth 
and retention. The majority of equity compensation is delivered in stock options, which have no intrinsic value unless 
the stock price appreciates. Awards of restricted stock units foster equity ownership and encourage retention. 
Restricted stock units also require fewer shares than an equivalent grant value in stock options. We target equity 
compensation at the median of the competitive market.  

     Our policy with regard to the timing of grants of equity compensation is to issue equity awards in the form of 
options and restricted stock units in connection with an employee’s hire date, or promotion date as well as in 
connection with an annual grant of equity awards that generally occurs in August of each year. All employee grants 
are approved by the Compensation Committee at its regularly scheduled quarterly meeting with the grant date on or 
after the approval date. The timing of grant dates is not based on any favorable or unfavorable non-public 
information anticipated to be disclosed at a later date. All stock option awards are granted with an exercise price 
equal to the closing sale price of our common stock on the Nasdaq Global Market on the date of grant.  

     Stock options typically vest over a four-year period, with a one-year cliff for 25% of the award and 1/48 of the 
award vesting monthly thereafter. Options expire ten years from the date of grant. Awards of restricted stock units 
vest 25% per year over four years. The vesting of all awards ceases when an employee leaves our employ.  

     The named executive officers received awards in August 2008 that vest on a time basis as part of the annual 
grants of equity awards. These awards were made in accordance with the guidelines adopted by the Compensation 
Committee.  

     In February 2008, the Compensation Committee recommended to the Board of Directors and the Board of 
Directors authorized the Compensation Committee to grant a specified number of restricted stock units to the 
majority of our employees, including executives. This proposal was designed to encourage employee retention during 
a busy and critical period for us. A total of 1,678,674 restricted stock units were granted. All units remain unvested 
until June 30, 2009, at which point they will fully vest.  

     On July 9, 2008, we announced an Offer to Exchange Outstanding Options to Purchase Common Stock, or the 
Offer, under which we offered eligible employees, including our named executive officers, the opportunity to 
exchange up to an aggregate of 5,417,840 shares underlying of their out-of-the money stock options, on a grant by 
grant basis, for a reduced number of restricted stock units that vest according to the following vesting schedule: 50% 
on August 1, 2009, 25% on February 1, 2010, and 25% on August 1, 2010. Eligible options consisted of outstanding 
stock options under the Plan that had an exercise price equal to or greater than $7.00 per share. Eligible employees 
included all persons employed by us as of the Offer date and excluded members of the Board of Directors who were 
not our employees. Additionally, the Offer permitted eligible options that were subject to performance-based vesting 
to be exchanged for restricted stock units that vest in three installments as follows: 20% upon the acceptance by the 
FDA of a filing of an NDA for AFRESA, 30% upon approval from the FDA to market AFRESA and 50% upon the 
first commercial sale of AFRESA. The Offer expired on August 6, 2008. Pursuant to the Offer, we accepted for 
exchange options to purchase an aggregate of 4,493,509 shares of our common stock from 322 eligible participants, 
representing 83% of the shares subject to options that were eligible to be exchanged in the Offer.  

Other Benefits  

     We provide a competitive benefits package to all full-time employees, which includes health and welfare benefits, 
such as medical, dental, vision care, life insurance benefits, and a 401(k) savings plan. Executives, including the 
named executive officers, receive additional benefits, including additional life insurance, as well as short-term and 
long-term disability insurance.  

     In November 2008, the Compensation Committee approved a benefit that would make our medical plans available 
to executives who retire from employment with us after reaching age 65 or early (age 55 - 64). Early retiring 
executives would be able to access all of the Aetna plans currently offered to active employees and the Aetna 
Premium PPO plan would be available to retirees age 65 and over as a supplement to Medicare coverage. The 
premiums for these plans will be paid 100% by the retiring executive.  

     In 2008, our executive officers also received an automobile allowance of $1,000 per month. Mr. Edstrom received 
an automobile allowance of $1,300 per month. Mr. Mann received no automobile allowance in 2008. We have no 
other structured perquisite benefits (e.g. club memberships or financial planning services) for any executive officer, 
including the named executive officers, and we currently do not provide any deferred compensation programs or 
supplemental pensions to any executive officer, including the named executive officers.

Table of Contents 

     In order to encourage stock ownership and provide greater incentives to contribute to our success at all levels, we 
provide all employees, including executive officers, the ability to purchase our common stock at a discount. The plan 
is designed to comply with section 423 of the Internal Revenue Code and provides all employees with the 
opportunity to purchase up to $25,000 of common stock annually at a purchase price that is the lower of 85% of the 
fair market value of the common stock on either the date of purchase or the commencement of the offering period. 
The executive’s rights under the employee stock purchase plan are identical to those of all other employees.  

Severance Provisions  

     We have entered into severance agreements with our executives, including each of the named executive officers 
other than Mr. Mann, in order to ensure that we have the continued dedication of such executives and in order to 
provide such executives with reasonable compensation and benefit arrangements in the event of termination of their 
employment. We believe that it is imperative to diminish any distraction of our executives arising from the personal 
uncertainty and insecurity that arises in the absence of any assurance of job security, thereby allowing executives to 
focus on corporate objectives and strategy. The terms of these agreements and amounts that may be realized are 
detailed under the heading “Potential Payments Upon Termination Or Change Of Control.”  

Change in Control Provisions  

     We have entered into change of control agreements with our executives, including each of the named executive 
officers other than Mr. Mann, in order to ensure that we have the continued dedication of such executives and in 
order to provide such executives with reasonable compensation and benefit arrangements in the event of termination 
of their employment following a change of control. We believe that it is imperative to diminish any distraction of our 
executives arising from the personal uncertainty and insecurity that arises in the absence of any assurance of job 
security, thereby allowing executives to focus on corporate objectives and strategy. The terms of these agreements 
and amounts that may be realized are detailed under the heading “Potential Payments Upon Termination Or Change 
of Control.”

Grants of Plan-Based Awards  

     We grant options and restricted stock units to our employees, including the named executive officers, under the 
Plan. All options granted to our named executive officers are nonstatutory stock options that do not qualify as 
incentive stock options within the meaning of Section 422 of the Code. As of December 31, 2008, 5,591,101 options 
and 5,947,408 restricted stock units were outstanding under the Plan and an additional 2,048,783 shares of common 
stock were available for issuance under the Plan. Options expire ten years from date of grant.  

     The exercise price per share of each option granted to our named executive officers was equal to the fair market 
value on the date of the grant. The exercise price is payable in cash, shares of our common stock previously owned 
by the optionee or pursuant to the net exercise of the option.  

     The following table summarizes option grants to the named executive officers during the fiscal year ended 
December 31, 2008, and the value of the underlying securities held by each of these individuals at December 31, 
2008. No stock appreciation rights covering our common stock were granted to any named executive officer in 2008.

(1)   We have entered into severance and change of control agreements with our executives, including each of the 

named executive officers other than Mr. Mann. Accordingly, there are no potential payments to Mr. Mann upon 
termination or change of control.

(2)   Represents the estimated cost of providing or paying for continuing medical and dental coverage for 18 months. 
The amounts for medical and dental insurance coverage are based on rates charged to our employees for post-
employment coverage provided in accordance with the Consolidated Omnibus Reconciliation Act of 1985, or 
COBRA.

(3)   Represents the fair value of the stock options held by the named executive officer that would be exercisable for a 
period ending on the earlier of 18 months following the triggering event or the end of the original term of the 
option.

(4)   Per SEC rules, the intrinsic value of accelerated unvested stock options shown in the table above was calculated 
using the closing price of our common stock on December 31, 2008 ($3.43). The intrinsic value is the aggregate 
spread between $3.43 and the exercise price of the accelerated options, if less than $3.43.

   Executive Severance Agreements  

We have entered into executive severance agreements with Messrs. Edstrom and Pfeffer, Drs. Richardson, Martens, 
and Thomson, and Ms. Palumbo. Each agreement is for a period of two years and will be automatically renewed for 
additional one-year periods unless either party gives notice to terminate the agreement at least 90 days prior to the 
end of its initial term or any subsequent term.  

The agreements provide that each executive is an “at will” employee and that his employment with us may be 
terminated at any time by the employee or us. Under the agreements, in the event we terminate an executive’s 
employment without cause (as defined below) or the employee terminates his employment with us for good reason 
(as defined below), the employee is generally entitled to receive the following:  

(cid:129)   the portion of the employee’s annual base salary earned through the termination date that was not paid prior to 

his termination, if any;

(cid:129)   on the condition the employee executes a general release and settlement agreement, or release, in favor of us, the 
employee’s annual base salary on the date of termination for a period of 18 months following his termination, 
subject to certain limitations;

(cid:129)   on the condition the employee executes a release, an amount equal to the average annual bonus received by the 
employee for the three years prior to his termination (or the prior period up to three years during which the 
employee was one of our executive officers and received a bonus);

(cid:129)   in the event the employee met the performance criteria for earning an annual bonus prior to his termination, a 

portion of the annual bonus earned for the year based on the number of days worked during the year;

(cid:129)   any compensation previously deferred by the employee and any accrued paid time-off that the employee is 

entitled to under our policy; and

(cid:129)   on the condition the employee executes a release, health insurance and, under certain circumstances, life, 

disability and other insurance benefits for a period expiring on the earlier of 18 months following his termination 
or until he qualifies for related benefits from another employer.

In addition, the executive severance agreements provide that, on the condition the employee executes a release, each 
vested stock option held by the employee on the date of termination will be exercisable for a period ending on the 
earlier of 18 months following that date or the end of the original term of the option.  

Under the agreements, an employee may be terminated for cause if he, among other things:  

(cid:129)   refuses to carry out or satisfactorily perform any of his lawful duties or any lawful instruction of our Board of 

Directors or senior management;

(cid:129)   violates any local, state or federal law involving the commission of a crime other than a minor traffic offense;

(cid:129)   is grossly negligent, engages in willful misconduct or breaches a fiduciary obligation to us;

(cid:129)   engages in any act that materially compromises his reputation or ability to represent us with investors, customers 

or the public; or

(cid:129)   reaches a mandatory retirement age established by us.

Under the agreements, good reason includes, among other things:  

(cid:129)   a reduction of the executive’s annual base salary to a level below his salary as of October 10, 2007 (April 21, 

2008 in the case of Mr. Pfeffer);

(cid:129)   a material diminution in the executive’s position, authority, duties or responsibilities with us, subject to certain 

limitations;

(cid:129)   an order by us to relocate the executive to an office located more than 50 miles from the executive’s current 

residence and worksite;

(cid:129)   any non-renewal of the executive severance agreement by us, on the condition that the executive may terminate 
the agreement for good reason only during the 30-day period after he receives notice from us that we intend to 
terminate the agreement; and

(cid:129)   any material violation of the executive severance agreement by us.

Under the agreements, an employee must inform us if he intends to terminate his agreement for good reason. We 
have 30 days from the date we receive notice of the employee’s intent to terminate the agreement for good reason to 
cure the default.  

     Transition Agreement with Mr. Anderson  

On December 20, 2007, we entered into an agreement with Mr. Anderson setting forth the terms of Mr. Anderson’s 
transition to the position of Corporate Vice President — Office of the Chairman, which commenced on April 1, 
2008. In this new position, Mr. Anderson continues to report to Hakan Edstrom, our President and Chief Operating 
Officer, and works not less than 75% of a full-time schedule, for which Mr. Anderson is paid a salary equal to 75% 
of his salary in effect immediately prior to his transition to the

new position. Mr. Anderson is eligible for a 2008 year-end bonus that will be proportionately adjusted to reflect the 
total salary paid to him during the year (as a percentage of the total salary that would have been paid to him if he had 
not transitioned to the new position). Upon his retirement on March 31, 2009, all of Mr. Anderson’s unvested stock 
options and restricted stock unit awards that were subject to time-based vesting become vested, and the stock options 
will be exercisable until March 31, 2011, on which date any unexercised stock options will expire.  

Under the agreement, Mr. Anderson continues as an at-will employee, and his employment may be terminated by 
either party prior to March 31, 2009. If we terminate Mr. Anderson’s employment without cause (as defined in our 
standard form of executive severance agreement) or if Mr. Anderson terminates his employment for good reason (as 
defined in our standard form of executive severance agreement) or Mr. Anderson dies or becomes disabled, we must 
pay Mr. Anderson (i) an amount equal to the salary that he would have been paid had he worked until March 31, 
2009, (ii) an amount equal to the average bonus paid or payable to Mr. Anderson for the three years preceding the 
year in which his employment terminates, and (iii) the premiums on the health insurance and additional health 
coverage for Mr. Anderson and his family members until March 31, 2009.  

     Change of Control Agreements  

We have entered into change of control agreements with Messrs. Edstrom and Pfeffer, Drs. Richardson, Martens, and 
Thomson, and Ms. Palumbo. Each agreement is for a period of two years and will be automatically renewed for 
additional one-year periods unless either party gives notice to terminate the agreement at least 90 days prior to the 
end of its initial term or any subsequent term.  

Under the agreements, a change of control will be deemed to occur upon:  

(cid:129)   any transaction that results in a person or group acquiring beneficial ownership of 50% or more of our voting 

stock, other than us, one of our employee benefit plans, Mr. Mann or any other entity in which Mr. Mann holds a
majority of the beneficial interests;

(cid:129)   any merger, consolidation or reorganization of us in which our stockholders immediately prior to the transaction 

hold less than 50% of the voting power of the surviving entity following the transaction, subject to certain 
limitations;

(cid:129)   any transaction in which we sell all or substantially all of our assets, subject to certain limitations;

(cid:129)   our liquidation; or

(cid:129)   any reorganization of our Board of Directors in which our incumbent directors (as defined in the agreements) 

cease for any reason to constitute a majority of the members of our board.

The agreements provide that in the event of a change of control, the employee is generally entitled to maintain the 
same position, authority and responsibilities held before the change of control, as well as the following compensation 
and benefits during the period ending on the earlier of 24 months following the change of control or the termination 
of his employment with us:  

(cid:129)   his annual base salary in an amount equal or greater to his annual salary as of the date the change of control 

occurs;

(cid:129)   an annual bonus in an amount equal to the average annual bonus received by him for the three years prior to his 
termination (or the prior period up to three years during which he was one of our executive officers and received 
a bonus);

(cid:129)   medical, dental and other insurance, and any other benefits we may offer to our executives; and

(cid:129)   prompt reimbursement for all reasonable employment expenses incurred by him in accordance with our policies 

and procedures.

Under the change of control agreements, we may terminate an executive with or without cause (as defined below) 
and the executive may terminate his employment with us for good reason (as defined below) or any reason at any 
time during the 2-year period following a change of control. In the event we terminate an executive without cause or 
an executive terminates his employment with us for good reason, he is generally entitled to receive the following:  

(cid:129)   the portion of his annual base salary earned through the termination date that was not paid prior to his 

termination, if any;

(cid:129)   on the condition the employee executes a release, the employee’s annual base salary on the date of termination 

for a period of 18 months following his termination, subject to certain limitations;

(cid:129)   on the condition the employee executes a release, an amount equal to 150% of his average annual bonus 

received by the employee for the three years prior to his termination (or the prior period up to three years during 
which the employee was one of our executive officers and received a bonus);

(cid:129)   in the event the employee met the performance criteria for earning an annual bonus prior to his termination, a 

portion of the annual bonus earned for the year based on the number of days worked during the year;

(cid:129)   any compensation previously deferred by the employee and any accrued paid time-off that the employee is 

entitled to under our policy; and

(cid:129)   on the condition the employee executes a release, health insurance and, under certain circumstances, life, 

disability and other insurance benefits for a period expiring on the earlier of 18 months following his termination 
or until he qualifies for related benefits from another employer.

In addition, the agreements provide that, on the condition the employee executes a release, each option to purchase 
shares of our common stock held by him as of the termination date will become fully vested and exercisable at any 
point during the term of the option, subject to certain limitations.  

Under the agreements, in the event we terminate an employee with cause or an employee terminates his employment 
with us without good reason, his agreement will terminate without any further obligation to either party.  

The change of control agreements provide that an employee may be terminated for cause if he, among other things:  

(cid:129)   refuses to carry out or satisfactorily perform any of his lawful duties or any lawful instruction of our Board of 

Directors or senior management;

(cid:129)   violates any local, state or federal law involving the commission of a crime other than a minor traffic offense;

(cid:129)   is grossly negligent, engages in willful misconduct or breaches a fiduciary obligation to us;

(cid:129)   engages in any act that materially compromises his reputation or ability to represent us with investors, customers 

or the public; or

(cid:129)   reaches a mandatory retirement age established by us before a change of control occurs.

Under the agreements, good reason includes, among other things:  

(cid:129)   a failure by us to make all compensation payments and provide all insurance and related benefits to the 

employee required under the agreement during his employment following a change of control, subject to certain 
limitations;

(cid:129)   a material diminution in the employee’s position, authority, duties or responsibilities with us;

(cid:129)   an order by us to relocate the employee to an office located more than 50 miles from the employee’s current 

residence and worksite;

(cid:129)   any non-renewal of the change of control agreement by us, on the condition that the employee may terminate the 

agreement for good reason only during the 30-day period after he receives notice from us that we intend to 
terminate the agreement; and

(cid:129)   any material violation of the change of control agreement by us.

Under the change of control agreements, an employee must inform us if he intends to terminate his agreement for 
good reason. We have 30 days from the date we receive notice of the employee’s intent to terminate the agreement 
for good reason to cure the default.  

The executive and change of control agreements provide that in the event an executive becomes entitled to benefits 
under both agreements, compensation payments and other benefits will be coordinated to ensure the executive is 
entitled to receive the benefits described above without duplicating coverage.

COMPENSATION OF DIRECTORS  

Fees  

Each of our non-employee directors receives an annual retainer of $25,000 for service on the Board of Directors. 
Each of our non-employee directors who serve as a committee chairman receives, in addition to the annual retainer, 
an additional retainer of $3,000 per year for his or her service as committee chairman and committee members 
receive an additional retainer of $2,000 per year; provided, however, the Audit Committee chairman’s additional 
retainer is $8,000 per year and each Audit Committee members’ additional retainer is $4,000 per year. Each of our 
non-employee directors also receives $2,000 for each meeting of the Board of Directors attended, and $750 for 
attending each meeting of any committee of the Board of Directors on which he or she serves. In the fiscal year 
ended December 31, 2008, the total compensation paid to non-employee directors was $336,050. The members of the 
Board of Directors are also eligible for reimbursement for their expenses incurred in attending Board of Directors 
meetings in accordance with Company policy.  

Options  

Each non-employee director of the Company also receives stock option grants under the 2004 Non-Employee 
Directors’ Stock Option Plan, or the Directors’ Plan. Only non-employee directors of the Company or an affiliate of 
such directors (as defined in the Internal Revenue Code of 1986, as amended, or the Code) are eligible to receive 
options under the Directors’ Plan. Options granted under the Directors’ Plan are intended by the Company not to 
qualify as incentive stock options under the Code.  

Option grants under the Directors’ Plan are non-discretionary. Pursuant to the terms of the Directors’ Plan, each of 
our non-employee directors automatically receives, and each person who is elected or appointed for the first time to 
be a non-employee director will automatically receive, on the date of his or her initial election or appointment to our 
Board of Directors, an option to purchase 30,000 shares of our common stock as an initial grant, or the Initial Option. 
On the date of each of our annual stockholder meetings, each non-employee director is automatically granted an 
option to purchase 10,000 shares of our common stock as an annual grant under the Directors’ Plan, or the Annual 
Option. However, if a non-employee director has not been serving as a non-employee director for the entire period 
beginning from the preceding annual stockholders meeting, then the number of shares subject to such Annual Option 
shall be reduced proportionately for each full quarter prior to the date of the Annual Option during which such person 
did not serve as a non-employee director. No other options may be granted at any time under the Directors’ Plan.  

The exercise price of options granted under the Directors’ Plan cannot be less than 100% of the fair market value of 
the common stock subject to the option on the date of the option grant. Acceptable consideration for the purchase of 
our common stock issued under the Directors’ Plan will be determined by our Board of Directors and may include 
cash or common stock previously owned by the optionee or may be paid through a broker assisted exercise or net 
exercise feature. All Initial Options vest in equal annual installments over three years. All Annual Options vest 
monthly over a period of three years. An optionee whose service relationship with us or any of our affiliates, whether 
as a non-employee director or subsequently as an employee, director or consultant to either us or one of our affiliates, 
ceases for any reason may exercise options for the term provided in the option agreement to the extent the options 
were exercisable on the date of termination. The term of options granted under the Directors’ Plan is ten years.  

Our Board of Directors will administer the Directors’ Plan, but the Board of Directors may delegate authority to 
administer the Directors’ Plan to a committee of one or more members of the board. The Board of Directors has 
broad discretion to interpret and administer the Directors’ Plan. Our Board of Directors may amend or terminate the 
Directors’ Plan at any time. However, some amendments will require stockholder approval and no amendment or 
termination may adversely affect a non-employee directors’ outstanding options without the non-employee directors’ 
written consent.  

In the event of a merger of us with or into another corporation or a consolidation, acquisition of assets or other 
change-in-control transaction involving us, the option will terminate if not exercised prior to the consummation of 
the transaction, unless the surviving entity or acquiring corporation chooses to assume any stock options outstanding 
under the Directors’ Plan or substitute similar stock options for those outstanding under the plan. Our Board of 
Directors will make appropriate adjustments for a stock split, reverse stock split, stock dividend, combination or 
reclassification of the stock, or any other increase or decrease in the number of issued shares of common stock 
effected without our receipt of consideration.

(1)   These amounts reflect expense recognized by us in 2008. Reference Note 10 “Stock Award Plans” our financial 
statements for the period ended December 31, 2008, included in Part IV of this Form 10-K which identifies the 
assumptions made in the valuation of option awards in accordance with FAS 123R. All non-employee directors 
received a stock option to purchase 10,000 shares of our common stock upon re-election to the Board of 
Directors on May 22, 2008 and an additional grant of 22,000 options on August 13, 2008. Options granted to 
non-employee directors vest monthly over a period of three years. The exercise price per share represents the 
fair market value of such common stock on the date of each respective grant (based on the closing sales price 
reported on the Nasdaq Global Market on the date of grant). We have no consulting agreements with any of our 
directors pursuant to which stock awards were issued. As of December 31, 2008, our non-employee directors 
had option grants outstanding to purchase 529,500 shares of our common stock.

received restricted stock award grant of 10,000 shares on August 13, 2008. Restricted stock awards granted to 
non-employee directors vest annually over a period of three years. As of December 31, 2008, our non-employee 
directors had restricted stock grants outstanding to receive 60,000 shares of our common stock.

(3)   On December 1, 2008, Heather Hay Murren, resigned from the Board of Directors effective immediately given 
that, having re-assumed the role of Chief Executive Officer of the Nevada Cancer Institute, she anticipated that 
her increased duties would prevent her from continuing as a director.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION  

During the fiscal year ended December 31, 2008, Messrs. Cohen and Kresa served on our Compensation Committee. 
Neither Mr. Cohen nor Mr. Kresa has ever been one of our officers or employees. During 2008, none of our

Item 12. Security Ownership of Certain Beneficial Owners and Management and Related Stockholder Matters  

SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT  

The following table sets forth certain information regarding the ownership of the Company’s common stock as of 
January 31, 2009 by: (i) each director and nominee for director; (ii) each of the executive officers named in the 
Summary Compensation Table; (iii) all executive officers and directors of the Company as a group; and (iv) all those 
known by the Company to be beneficial owners of more than five percent of its common stock. The table is based 
upon information supplied by our officers, directors and principal stockholders and a review of Schedules 13D and 
13G, if any, filed with the SEC. Unless otherwise indicated in the footnotes to the table and subject to community 
property laws where applicable, we believe that each of the stockholders named in the table has sole voting and 
investment power with respect to the shares indicated as beneficially owned.  

Applicable percentages are based on 102,013,623 shares outstanding on January 31, 2009, adjusted as required by 
rules promulgated by the SEC. These rules generally attribute beneficial ownership of securities to persons who 
possess sole or shared voting power or investment power with respect to those securities. In addition, the rules 
include shares of common stock issuable pursuant to the exercise of stock options or warrants that are either 
immediately exercisable or exercisable on April 1, 2009, which is 60 days after January 31, 2009. These shares are 
deemed to be outstanding and beneficially owned by the person holding those options or warrants for the purpose of 
computing the percentage ownership of that person, but they are not treated as outstanding for the purpose of 
computing the percentage ownership of any other person. Certain of the options in this table are exercisable at any 
time but, if exercised, are subject to a lapsing right of repurchase until the options are fully vested. Except as 
otherwise noted in the table, the address for each person or entity listed in the table is c/o MannKind Corporation, 
28903 North Avenue Paine, Valencia, CA 91355.

(1)   Includes 2,048,783 shares available for issuance under the Plan and 977,488 shares available for purchase under 

our 2004 Employee Stock Purchase Plan. On the first day of each calendar year, for a period of ten years 
beginning on January 1, 2005, the share reserve under our 2004 Employee Stock Purchase Plan will 
automatically increase by the lesser of 700,000 shares or 1% of the total number of shares of our common stock 
outstanding on that date, or by an amount to be determined by our Board of Directors. On January 1, 2009, the 
available shares for purchase under our 2004 Employee Stock Purchase Plan was increased by 700,000 shares.

(2)   Includes options to purchase 27,315 shares under the AlleCure Corp. 2000 Stock Option and Stock Plan and the 
CTL ImmunoTherapies Corp. 2000 Stock Option and Stock Plan granted to employees and options to purchase 
240,972 shares granted to Mr. Mann outside of our plans. Mr. Mann’s options have the same terms as those 
granted under the Plan, described elsewhere in this proxy statement, and have an exercise price of $25.23 per 
share. All of these options were exercisable as of December 31, 2008.

The equity compensation plans that were in effect as of December 31, 2008 and that were adopted without the 
approval of our security holders are the AlleCure Corp. 2000 Stock Option and Stock Plan and the CTL 
ImmunoTherapies Corp. 2000 Stock Option and Stock Plan. The material terms of these plans are described below.

In connection with the acquisition by us of AlleCure Corp. and CTL ImmunoTherapies Corp. on December 12, 2001, 
we assumed all of the outstanding options granted under the AlleCure Corp. 2000 Stock Option and Stock Plan, or 
the AlleCure plan, and the CTL ImmunoTherapies Corp. 2000 Stock Option and Stock Plan, or the CTL plan. 
Subsequent to the acquisition, these options were adjusted to cover shares of our common stock at the exchange 
ratios set forth in the applicable merger agreements. As of December 31, 2007, options to purchase an aggregate of 
34,296 shares of our common stock under the AlleCure plan and the CTL plan were outstanding. The AlleCure plan 
and CTL plan were terminated and we will not grant additional equity awards under the AlleCure plan or the CTL 
plan, which we collectively refer to as the 2000 plans.  

     Share reserve. Except with respect to the outstanding options referenced above, no shares of our common stock 
remain reserved or available for issuance under the 2000 plans.  

     Administration. Pursuant to the merger, our Board of Directors administers the 2000 plans, but the Board of 
Directors may delegate authority to administer the 2000 plans to a committee that complies with applicable law. Our 
Board of Directors has broad authority to administer the 2000 plans.  

     Eligibility of awards. The 2000 plans provided for the grant of ISOs, NSOs and stock purchase rights to 
employees, directors and consultants.  

     Stock options. Stock options were granted under the 2000 plans pursuant to a stock option agreement. Options 
granted under the 2000 plans have a maximum term of ten years and vest at the rate specified in the option 
agreements. Except in the case of options granted to officers, directors, and consultants, options become exercisable 
at a rate of no less than 20% per year over five years from the date the options were granted.  

Acceptable consideration for the purchase of common stock issued pursuant to options granted under the 2000 plans 
includes cash, common stock previously owned by the optionee, a promissory note or consideration received through 
a cashless exercise program.  

Generally, options under the 2000 plans may not be sold, pledged, assigned, hypothecated, transferred or disposed of 
in any manner other than by will or by laws of descent and distribution and may be exercised, during the lifetime of 
the optionee, only by the optionee.  

Unless an optionee’s stock option agreement provides for earlier termination, if an optionee’s service relationship 
with us terminates due to disability or death, the optionee, or his or her beneficiary, generally may exercise any 
vested options for up to twelve months after the date the service relationship ends. If an optionee’s relationship with 
us ceases for any reason other than disability or death, the optionee may exercise his or her option within the time 
specified in the option agreement, or if not specified, for three months. In no event may an option be exercised after 
the expiration of the term of the option set forth in the option agreement.  

The administrator may at any time offer to buy out for a payment in cash or shares, an option previously granted, 
based on such terms and conditions as the administrator may establish and communicate to the optionee at the time 
such offer is made.  

     Stock purchase rights. Unless the administrator determines otherwise, a restricted stock purchase agreement 
grants us a repurchase option exercisable upon the voluntary or involuntary termination of the purchaser’s service 
with us for any reason (including death or disability). The purchase price for shares repurchased pursuant to the 
restricted stock purchase agreement is the original price paid by the purchaser and may be paid by cancellation of any 
indebtedness of the purchaser. The repurchase option lapses at such rate as the administrator may determine. Except 
with respect to shares purchased by officers and directors, the repurchase option lapses at a rate of no less than 20% 
per year over five years from the date of purchase.  

     Corporate transactions or changes in control. Our Board of Directors will make appropriate adjustments for a 
stock split, reverse stock split, stock dividend, combination or reclassification of the stock, or any other increase or 
decrease in the number of issued shares of common stock effected without receipt of consideration by the company.  

In the event of the proposed dissolution or liquidation of the company, the administrator shall notify each optionee as 
soon as practicable prior to the effective date of such proposed transaction. The administrator in its discretion may 
provide for an optionee to have the right to exercise his or her option or stock purchase right until fifteen days prior 
to such transaction as to all of the optioned stock covered thereby, including shares as to which the option or stock 
purchase right would not otherwise be exercisable. In addition, the administrator may provide that any company 
repurchase option applicable to any shares purchased upon exercise of an option or stock purchase right shall lapse as 
to all such shares, provided the proposed dissolution or liquidation takes place at the time and in the  

70

                                   
Table of Contents 

manner contemplated. To the extent it has not been previously exercised, an option or stock purchase right will 
terminate immediately prior to the consummation of such proposed action.  

In addition, in the event we merge or sell all or substantially all of our assets, all outstanding stock awards under the 
2000 plans will be assumed, continued or substituted for by any surviving or acquiring entity. If the surviving or 
acquiring entity elects not to assume, continue or substitute for these awards, each participant will be given notice of 
the transaction and permitted to exercise all outstanding awards held under the 2000 plans for a period of fifteen days 
after notice is provided. To the extent it has not been previously exercised, an option or stock purchase right will 
terminate at the end of such period.  

Additional provisions. Our Board of Directors has the authority to amend outstanding awards granted under the 2000 
plans, except that no amendment may adversely affect an award without the recipient’s written consent. Our Board of 
Directors has the power to amend the 2000 plans. We are required to provide annual financial statements to 
participants in the 2000 plans.  

Item 13. Certain Relationships and Related Transactions, and Director Independence  

CERTAIN TRANSACTIONS  

The following is a description of transactions or series of transactions since January 1, 2008 to which we have been a 
party, in which the amount involved in the transaction or series of transactions exceeds $120,000, and in which any 
of our directors, executive officers or persons who we know held more than five percent of any class of our capital 
stock, including their immediate family members, had or will have a direct or indirect material interest, other than 
compensation arrangements, which are described under “Management.” We believe that the terms obtained or 
consideration that we paid or received, as applicable, in connection with the transactions described below were 
comparable to terms available or the amounts that would be paid or received, as applicable, in arm’s-length 
transactions. In accordance with its charter, our Audit Committee approves or ratifies any related party transaction as 
required by NASDAQ rules.  

SALES OF COMMON STOCK  

Since January 1, 2008, we sold shares of our common stock as follows:  

(cid:129)   on June 30, 2008, we sold shares of common stock through our Employee Stock Purchase Plan at a purchase 

price of $2.60 per share to among other employees the following executive officers:

On October 2, 2007, we entered into a new loan arrangement with Mr. Mann to borrow up to a total of 
$350.0 million before January 1, 2010. This new arrangement replaced the existing loan arrangement with Mr. Mann 
to borrow up to $150.0 million through August 1, 2008. On December 29, 2008, we received an installment of 
$30.0 million against this advance. As of December 31, 2008, the amount outstanding under the arrangement was 
$30.0 million. On February 26, 2009, as a result of our principal stockholder being licensed as a finance lender under 
the California Finance Lenders Law, the promissory note underlying the loan arrangement was revised to reflect the 
lender as The Mann Group LLC, or the Lender, an entity controlled by Mr. Mann. This new license also eliminated 
the draw restrictions under the previous loan arrangement and we are now able to borrow up to a total of 
$350.0 million from time to time with appropriate notice to the Lender.

In connection with certain meetings of our Board of Directors and on other occasions when our business necessitated 
air travel for Mr. Mann and other MannKind employees, we utilized Mr. Mann’s private aircraft and we paid the 
charter company that manages the aircraft on behalf of Mr. Mann approximately $130,000 in 2008 on the basis of the 
corresponding cost of commercial airfare.  

The above related-party transactions were approved by a majority or more of the disinterested members of our Board 
of Directors. We believe that the foregoing agreements were and continue to be in our best interests. It is our current 
policy that all agreements between us and any of our officers, directors, 5% stockholders, or any of their affiliates, 
will be entered into only if such agreements are approved by a majority of our disinterested directors and are on 
terms no less favorable to us than could be obtained from unaffiliated parties.  

INDEPENDENCE OF THE BOARD OF DIRECTORS  

As required under the Nasdaq Stock Market, or Nasdaq, listing standards, a majority of the members of a listed 
company’s Board of Directors must qualify as “independent,” as affirmatively determined by the Board of Directors. 
The Board of Directors consults with our counsel to ensure that the board’s determinations are consistent with all 
relevant securities and other laws and regulations regarding the definition of “independent,” including those set forth 
in pertinent listing standards of the Nasdaq, as in effect time to time.  

Consistent with these considerations, after review of all relevant transactions or relationships between each director, 
or any of his family members, and us, our senior management and our independent auditors, the Board of Directors 
affirmatively has determined that all of our directors other than Mr. Mann and Mr. Edstrom are independent directors 
within the meaning of the applicable Nasdaq listing standards. In making this determination, the board found that 
none of the directors have a material or other disqualifying relationship with us.

The Audit Committee has adopted a policy and procedures for the pre-approval of audit and non-audit services 
rendered by our independent auditor, Deloitte. The policy generally pre-approves specified services in the defined 
categories of audit services, audit-related services, tax services and other services up to specified amounts. Pre-
approval may also be given on an individual explicit case-by-case basis before the independent auditor is engaged to 
provide each service. The pre-approval of services may be delegated to one or more of the Audit Committee’s 
members, but the decision must be reported to the full Audit Committee at its next scheduled meeting. The 
delegation of pre-approval of services is limited to non-audit services, as set forth in the Audit Committee Charter.  

The Audit Committee has determined that the rendering of the services other than audit services by Deloitte is 
compatible with maintaining Deloitte’s independence.

Report of Independent Registered Public Accounting Firm  

To the Board of Directors and Stockholders of MannKind Corporation 
Valencia, California  

     We have audited the accompanying balance sheets of MannKind Corporation (a development stage company) (the 
“Company”) as of December 31, 2007 and 2008 and the related statements of operations, stockholders’ equity 
(deficit), and cash flows for each of the three years in the period ended December 31, 2008 and for the period from 
February 14, 1991 (date of inception) to December 31, 2008. These financial statements are the responsibility of the 
Company’s management. Our responsibility is to express an opinion on the financial statements based on our audits.  

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

     In our opinion, such financial statements present fairly, in all material respects, the financial position of 
MannKind Corporation as of December 31, 2007 and 2008, and the results of its operations and its cash flows for 
each of the three years in the period ended December 31, 2008 and for the period from February 14, 1991 (date of 
inception) to December 31, 2008, in conformity with accounting principles generally accepted in the United States of 
America.  

     We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board 
(United States), the Company’s internal control over financial reporting as of December 31, 2008, based on the 
criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring 
Organizations of the Treadway Commission and our report dated February 27, 2009 expressed an unqualified 
opinion on the Company’s internal control over financial reporting.

MANNKIND CORPORATION AND SUBSIDIARIES 
(A Development Stage Company)  

NOTES TO FINANCIAL STATEMENTS  

1.  Description of Business and Basis of Presentation  

     Business — MannKind Corporation (the “Company”) is a biopharmaceutical company focused on the discovery, 
development and commercialization of therapeutic products for diseases such as diabetes and cancer. The 
Company’s lead product candidate, AFRESA, is an ultra rapid-acting insulin that has completed Phase 3 clinical 
trials which evaluated its safety and efficacy in the treatment of diabetes. AFRESA consists of the Company’s 
proprietary Technosphere particles onto which insulin molecules are loaded. These loaded particles are then 
aerosolized and inhaled deep into the lung using the Company’s AFRESA inhaler.  

     Basis of Presentation — The Company is considered to be in the development stage as its primary activities since 
incorporation have been establishing its facilities, recruiting personnel, conducting research and development, 
business development, business and financial planning, and raising capital. Since its inception through December 31, 
2008 the Company has reported accumulated net losses of $1.4 billion, which include a goodwill impairment charge 
of $151.4 million (see Note 2), and cumulative negative cash flow from operations of $1.0 billion. It is costly to 
develop therapeutic products and conduct clinical trials for these products. At December 31, 2008 the Company’s 
capital resources consisted of cash, cash equivalents, and marketable securities of $46.5 million and $320.0 million 
of available borrowings under the loan agreement with an entity controlled by the Company’s principal shareholder 
(see Note 7). Based upon the Company’s current expectations, management believes the Company’s existing capital 
resources will enable it to continue planned operations through the first quarter of 2010. However, the Company 
cannot provide assurances that its plans will not change or that changed circumstances will not result in the depletion 
of its capital resources more rapidly than it currently anticipates. Accordingly, the Company expects that it will need 
to raise additional capital, either through the sale of equity and/or debt securities, a strategic business collaboration 
with a pharmaceutical company or the establishment of other funding facilities, in order to continue the development 
and commercialization of AFRESA and other product candidates and to support its other ongoing activities.  

     On December 12, 2001, the stockholders of AlleCure Corp. (“AlleCure”) and CTL ImmunoTherapies Corp. 
(“CTL”) voted to exchange their shares for shares of Pharmaceutical Discovery Corporation (“PDC”). Upon 
approval of the merger, PDC then changed its name to MannKind Corporation. PDC was incorporated in the State of 
Delaware on February 14, 1991. The stockholders of PDC did not vote on the merger. At the date of the merger, 
Mr. Alfred Mann owned 76% of PDC, 59% of AlleCure and 69% of CTL. Accordingly, only the minority interest of 
AlleCure and CTL was stepped up to fair value using the purchase method of accounting. As a result of this purchase 
accounting, in-process research and development of $19.7 million and goodwill of $151.4 million were recorded at 
the entity level. The historical basis of PDC and the historical basis relating to the ownership interests of Mr. Mann in 
AlleCure and CTL have been reflected in the financial statements. For periods prior to December 12, 2001, the 
results of operations have been presented on a combined basis. All references in the accompanying financial 
statements and notes to the financial statements to number of shares, sales price and per share amounts of the 
Company’s capital stock have been retroactively restated to reflect the share exchange ratios for each of the entities 
that participated in the merger.  

     For periods subsequent to December 12, 2001, the accompanying financial statements have been presented on a 
consolidated basis and include the wholly-owned subsidiaries, AlleCure and CTL. On December 31, 2002, AlleCure 
and CTL merged with and into MannKind and ceased to be separate entities.  

     Segment Information — In accordance with Financial Accounting Standards Board (“FASB”) Statement No. 131, 
Disclosures about Segments of an Enterprise and Related Information, operating segments are identified as 
components of an enterprise about which separate discrete financial information is available for evaluation by the 
chief operating decision-maker in making decisions regarding resource allocation and assessing performance. To 
date, the Company has viewed its operations and manages its business as one segment operating entirely in the 
United States of America.  

2.  Summary of Significant Accounting Policies  

     Financial Statement Estimates — The preparation of financial statements in conformity with accounting 
principles generally accepted in the United States of America requires management to make estimates and 
assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results 
could differ from those estimates.  

87  

                                   
Table of Contents 

     Cash and Cash Equivalents — The Company considers all highly liquid investments with a purchased maturity 
date of three months or less to be cash equivalents.  

     Concentration of Credit Risk — Financial instruments that potentially subject the Company to concentration of 
credit risk consist of cash and cash equivalents and marketable securities. Cash and cash equivalents consist 
primarily of interest-bearing accounts and are regularly monitored by management and held in high credit quality 
institutions. Marketable securities consist of highly liquid short-term investment securities such as government and 
investment-grade corporate debt.  

     Marketable Securities — The Company accounts for marketable securities as available for sale, in accordance 
with FASB Statement No. 115, Accounting for Certain Debt and Equity Securities. Unrealized holding gains and 
losses for available-for-sale securities are reported as a separate component of stockholders’ equity until realized. 
The Company reviews the portfolio for other than temporary impairment in accordance with Emerging Issues Task 
Force (“EITF”) Issue No. 03-01, The Meaning of Other-Than-Temporary Impairment and Its Application to Certain 
Investments and Financial Accounting Standards Board (“FASB”) Staff Position No. 115-1, The Meaning of Other-
Than-Temporary Impairment and Its Application to Certain Investments.  

     State Research and Development Credit Exchange Receivable — The State of Connecticut provides certain 
companies with the opportunity to exchange certain research and development income tax credit carryforwards for 
cash in exchange for foregoing the carryforward of the research and development credits. The program provides for 
an exchange of research and development income tax credits for cash equal to 65% of the value of corporation tax 
credit available for exchange. Estimated amounts receivable under the program are recorded as a reduction of 
research and development expenses.  

     Fair Value of Financial Instruments — The carrying amounts of financial instruments, which include cash 
equivalents, marketable securities and accounts payable, approximate their fair values due to their relatively short 
maturities. The fair value of the note payable to related party cannot be reasonably estimated as the Company would 
not be able to obtain a similar credit arrangement in the current economic environment. The senior convertible notes 
had a carrying value of $111.8 million and $112.3 million and an estimated fair value of $95.2 million and 
$53.9 million as of December 31, 2007 and 2008, respectively.  

     Goodwill and Identifiable Intangibles — As a result of the merger with AlleCure and CTL on December 12, 
2001, as described in Note 1, goodwill of $151.4 million was recorded at the entity level in 2001. Upon adoption of 
FASB Statement No. 142, Goodwill and Other Intangible Assets, the Company adopted a policy of testing goodwill 
and intangible assets with indefinite lives for impairment at least annually, as of December 31, with any related 
impairment losses being recognized in earnings when identified. In December 2002 the Company concluded that the 
major AlleCure product development program should be terminated and that the clinical trials of the CTL product 
should be halted and returned to the research stage. As a result of this determination, the Company closed the CTL 
facility and reduced headcount for AlleCure and CTL by approximately 50%. In connection with the annual test for 
impairment of goodwill as of December 31, 2002, the Company determined that on the basis of the internal study, the 
goodwill recorded for the AlleCure and CTL units was potentially impaired. The Company performed the second 
step of the annual impairment test as of December 31, 2002 for each of the potentially impaired reporting units and 
estimated the fair value of the AlleCure and CTL programs using the expected present value of future cash flows 
which were expected to be negligible. Accordingly, the goodwill balance of $151.4 million was determined to be 
fully impaired and an impairment loss was recorded in 2002. Subsequent to December 31, 2002, the Company had 
no goodwill or intangibles with indefinite lives included on its balance sheet.  

     Property and Equipment — Property and equipment are recorded at cost and depreciated using the straight-line 
method over the estimated useful lives of the related assets. Leasehold improvements are amortized over the term of 
the lease or the service lives of the improvements, whichever is shorter. Assets under construction are not depreciated 
until placed into service.  

     Impairment of Long-Lived Assets — The Company evaluates long-lived assets for impairment whenever events or 
changes in circumstances indicate that the carrying value of an asset may not be recoverable in accordance with 
FASB Statement No. 144, Accounting for the Impairment or Disposal of Long Lived-Assets. Assets are considered to 
be impaired if the carrying value may not be recoverable based upon management’s assessment of the following 
events or changes in circumstances:  

88

                                   
Table of Contents 

(cid:129)   significant changes in the Company’s strategic business objectives and utilization of the assets;

(cid:129)   a determination that the carrying value of such assets can not be recovered through undiscounted cash flows;

(cid:129)   loss of legal ownership or title to the assets; or

(cid:129)   the impact of significant negative industry or economic trends.

     If the Company believes an asset to be impaired, the impairment recognized is the amount by which the carrying 
value of the assets exceeds the fair value of the assets. Any write-downs would be treated as permanent reductions in 
the carrying amount of the asset and an operating loss would be recognized. For the year ended December 31, 2006 
the Company did not consider any long-lived assets to be impaired based on management’s assessment. During the 
years ended December 31, 2007 and 2008, asset impairments of approximately $6.6 million and $0.5 million, 
respectively, were recognized as described in Note 5 — Property and Equipment.  

     Accounts Payable and Accrued Expenses — All liabilities, including accounts payable and accrued expenses, are 
recorded consistent with the definition of liabilities and accrual accounting as provided by FASB Statement of 
Financial Accounting Concepts No. 6, Elements of Financial Statements.  

     Income Taxes — In accordance with FASB Statement No. 109, Accounting for Income Taxes, deferred income tax 
assets and liabilities are recorded for the expected future tax consequences of temporary differences between the 
financial statement carrying amounts and the income tax basis of assets and liabilities. A valuation allowance is 
recorded to reduce net deferred income tax assets to amounts that are more likely than not to be realized (see Note 
14).  

     Income tax positions are considered for uncertainty in accordance with FASB Interpretation No. 48, Accounting 
for Uncertainty in Income Taxes — an interpretation of FASB Statement No. 109 (“FIN 48”). The provisions of FIN 
48 are effective beginning January 1, 2007. The Company believes that its income tax filing positions and deductions 
will be sustained on audit and does not anticipate any adjustments that will result in a material change to its financial 
position. Therefore, no reserves for uncertain income tax positions have been recorded pursuant to FIN 48. The 
cumulative effect, if any, of applying FIN 48 is to be reported as an adjustment to the opening balance of retained 
earnings in the year of adoption. The Company’s adoption of FIN 48 did not result in a cumulative effect adjustment 
to retained earnings.  

     Significant management judgment is involved in determining the provision for income taxes, deferred tax assets 
and liabilities and any valuation allowance recorded against net deferred tax assets. Due to uncertainties related to 
deferred tax assets as a result of the history of operating losses, a valuation allowance has been established against 
the gross deferred tax asset balance. The valuation allowance is based on management’s estimates of taxable income 
by jurisdiction in which the Company operates and the period over which deferred tax assets will be recoverable. In 
the event that actual results differ from these estimates or the Company adjusts these estimates in future periods, a 
change in the valuation allowance may be needed, which could materially impact the Company’s financial position 
and results of operations.  

Contingencies — Contingencies are recorded in accordance with FASB Statement No. 5, Accounting for 
Contingencies.  

     Stock-Based Compensation — As of December 31, 2008, the Company had three active stock-based 
compensation plans, which are described more fully in Note 10. On January 1, 2006, the Company adopted the 
provisions of FASB Statement No. 123R (“FASB Statement No. 123R”), Share-based Payment, which is a revision 
of FASB Statement No. 123 (“FASB Statement No. 123”), Accounting for Stock-Based Compensation. Prior to 
January 1, 2006, the Company accounted for employee stock options and the employee stock purchase plan using the 
intrinsic value method in accordance with Accounting Principles Board (“APB”) Opinion No. 25 (“APB No. 25”), 
Accounting for Stock Issued to Employees, and adopted the disclosure only alternative of FASB Statement No. 123. 
FASB Statement No. 123R eliminated the intrinsic value method of accounting for stock options which the Company 
followed until December 31, 2005. Further, FASB Statement No. 123R requires all share-based payments to 
employees, including grants of stock options and the compensatory elements of employee stock purchase plans, to be 
recognized in the income statement based upon the fair value of the awards at the grant date.  

     Upon adoption of FASB Statement No. 123R, the Company selected the modified prospective transition method 
whereby unvested awards at the date of adoption as well as awards that are granted, modified, or settled after the date 
of adoption will be measured and accounted for in accordance with FASB Statement No. 123R. Measurement and 
attribution of compensation cost for awards unvested

Table of Contents 

as of January 1, 2006 is based on the same estimate of the grant-date or modification-date fair value and the same 
attribution method (straight-line) used previously under FASB Statement No. 123.  

     Warrants — The Company has issued warrants to purchase shares of its common stock. Warrants have been 
accounted for as equity in accordance with the provisions of EITF Issue No. 00-19: Accounting for Derivative 
Financial Instruments Indexed to, and Potentially Settled in, a Company’s Own Stock.  

     Comprehensive Income (Loss) - Other Comprehensive Income (loss) (OCI) is recorded in accordance with FASB 
Statement No. 130, “Reporting Comprehensive Income”, which requires that all components of comprehensive 
income (loss) be reported in the financial statements in the period in which they are recognized. OCI includes certain 
changes in stockholders’ equity that are excluded from net income. Specifically, the Company includes in OCI 
unrealized gains and losses on our available-for-sale securities.  

     Research and Development Expenses — Research and development expenses consist primarily of costs associated 
with the clinical trials of the Company’s product candidates, manufacturing supplies and other development 
materials, including raw material purchases of insulin, compensation and other expenses for research and 
development personnel, costs for consultants and related contract research, facility costs, and depreciation. Research 
and development costs, which are net of any tax credit exchange recognized for the Connecticut state research and 
development credit exchange program, are expensed as incurred consistent with FASB Statement No. 2, Accounting 
for Research and Development Costs.  

     Clinical Trial Expenses — Clinical trial expenses, which are reflected in research and development expenses in 
the accompanying statements of operations, result from obligations under contracts with vendors, consultants, and 
clinical site agreements in connection with conducting clinical trials. The financial terms of these contracts are 
subject to negotiations which vary from contract to contract and may result in payment flows that do not match the 
periods over which materials or services are provided to the Company under such contracts. The appropriate level of 
trial expenses are reflected in the Company’s financial statements by matching period expenses with period services 
and efforts expended. These expenses are recorded according to the progress of the trial as measured by patient 
progression and the timing of various aspects of the trial. Clinical trial accrual estimates are determined through 
discussions with internal clinical personnel and outside service providers as to the progress or state of completion of 
trials, or the services completed. Service provider status is then compared to the contractually obligated fee to be paid 
for such services. During the course of a clinical trial, the Company may adjust the rate of clinical expense 
recognized if actual results differ from management’s estimates. The date on which certain services commence, the 
level of services performed on or before a given date and the cost of the services are often judgmental.  

     Interest Expense — Interest costs are expensed as incurred, except to the extent such interest is related to 
construction in progress, in which case interest is capitalized in accordance with FASB Statement No. 34, 
Capitalization of Interest Cost. Interest expense, net, for the years ended December 31, 2007 and 2008 was 
$3.4 million and $2.3 million, respectively. Interest costs capitalized for the years ended December 31, 2007 and 
2008 were $1.4 million and $2.5 million, respectively.  

     Net Loss Per Share of Common Stock — Basic net loss per share excludes dilution for potentially dilutive 
securities and is computed by dividing loss applicable to common stockholders by the weighted average number of 
common shares outstanding during the period. Diluted net loss per share reflects the potential dilution that could 
occur if securities or other contracts to issue common stock were exercised or converted into common stock. 
Potentially dilutive securities are excluded from the computation of diluted net loss per share for all of the periods 
presented in the accompanying statements of operations because the reported net loss in each of these periods results 
in their inclusion being antidilutive.  

     Potentially dilutive securities outstanding are summarized as follows:  

Exercise of common stock options
Conversion of senior convertible notes into common stock
Exercise of common stock warrants
Vesting of restricted stock units

     Exit or Disposal Activities — FASB Statement No. 146, Accounting for Costs Associated with Exit or Disposal 
Activities, was effective for exit or disposal activities initiated after December 31, 2002. FASB Statement No. 146 
addresses financial accounting and reporting for the costs associated with exit or disposal activities and EITF Issue 
No. 94-3, Liability Recognition for Certain Employee

     Termination Benefits and Costs to Exit and Disposal Activity (Including Certain Costs Incurred in a 
Restructuring). FASB Statement No. 146 requires that a liability for costs associated with an exit or disposal activity 
be recognized when the liability is incurred and establishes that fair value is the objective for initial measurements of 
the liability.  

     Recently Issued Accounting Standards — In December 2007, the FASB ratified the EITF consensus on EITF 
Issue No. 07-1, Accounting for Collaborative Arrangements, that discusses how parties to a collaborative 
arrangement (which does not establish a legal entity within such arrangement) should account for various activities. 
The consensus indicates that costs incurred and revenues generated from transactions with third parties (i.e. parties 
outside of the collaborative arrangement) should be reported by the collaborators on the respective line items in their 
income statements pursuant to EITF Issue No. 99-19, Reporting Revenue Gross as a Principal Versus Net as an 
Agent, Additionally, the consensus provides that income statement characterization of payments between the 
participants in a collaborative arrangement should be based upon existing authoritative pronouncements; analogy to 
such pronouncements if not within their scope; or a reasonable, rational, and consistently applied accounting policy 
election. EITF Issue No. 07-1 is effective beginning January 1, 2009 and is to be applied retrospectively to all periods 
presented for collaborative arrangements existing as of the date of adoption. Management believes that the adoption 
of EITF No. 07-1 will not have an impact on the Company’s results of operations, financial position or cash flows.  

     In December 2007, the FASB issued FASB Statement No. 141(R), “Business Combinations” and FASB 
Statement No. 160, “Accounting and Reporting of Noncontrolling Interests in Consolidated Financial Statements — 
an amendment of ARB No. 51” (“FASB Statement No. 160”). These standards will significantly change the 
accounting and reporting for business combination transactions and noncontrolling (minority) interests in 
consolidated financial statements, including capitalizing at the acquisition date the fair value of acquired IPR&D, and 
remeasuring and writing down these assets, if necessary, in subsequent periods during their development. These new 
standards will be applied prospectively for business combinations that occur on or after January 1, 2009, except that 
presentation and disclosure requirements of FASB Statement No. 160 regarding noncontrolling interests shall be 
applied retrospectively. Adoption of these statements are expected to have a significant effect on how acquisition 
transactions, subsequent to January 1, 2009, are reflected in the financial statements.  

     As of January 1, 2008, the Company adopted on a prospective basis certain required provisions of Statement of 
Financial Accounting Standards (“FASB Statement” ) No. 157, Fair Value Measurements (“FASB Statement 
No. 157”), as amended by FASB Financial Staff Position (“FSP”) No. 157-2. Those provisions relate to the 
Company’s financial assets and liabilities carried at fair value and its fair value disclosures related to financial assets 
and liabilities. FASB Statement 157 defines fair value, expands related disclosure requirements and specifies a 
hierarchy of valuation techniques based on the nature of the inputs used to develop the fair value measures. Fair 
value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly 
transaction between market participants at the measurement date. There are three levels of inputs to fair value 
measurements — Level 1, meaning the use of quoted prices for identical instruments in active markets; Level 2, 
meaning the use of quoted prices for similar instruments in active markets or quoted prices for identical or similar 
instruments in markets that are not active or are directly or indirectly observable; and Level 3, meaning the use of 
unobservable inputs. Observable market data should be used when available. All of the Company’s marketable 
securities are classified as available-for-sale securities and are carried at fair value. The Company’s valuation 
measurements for the available-for-sale securities are Level 2 measurements. The partial adoption of FASB 
Statement 157 did not have a significant impact on the Company’s results of operations, financial position or cash 
flows. The adoption of FASB Statement No. 157, as it relates to nonfinancial assets and liabilities will not have a 
material effect on the Company’s results of operations, financial position or cash flows.  

     In May 2008, the FASB issued FSP No. APB 14-1 (“FSP No. APB 14-1”), “ Accounting for Convertible Debt 
Instruments that may be Settled in Cash Upon Conversion (Including Partial Cash Settlement). ” FSP No. APB 14-1 
establishes that the liability and equity components of convertible debt instruments within the scope of FSP APB 
No. 14-1 shall be separately accounted for in a manner that will reflect the entity’s nonconvertible debt borrowing 
rate when interest cost is recognized in subsequent periods. The carrying amount of the liability component of the 
convertible debt instrument will be determined by measuring the fair value of a similar liability that does not have an 
associated equity component. The carrying value of the equity component will be determined by deducting the fair 
value of the liability component from the initial proceeds ascribed to the convertible debt instrument as a whole. 
Related transaction costs shall be allocated to the liability and equity components in proportion to the allocation of 
proceeds and accounted for as debt issuance costs and equity issuance costs, respectively. The excess of the principal 
amount of the liability component over its carrying amount shall be amortized to interest cost using the interest 
method. FSP No. APB 14-1 is effective beginning January 1, 2009 and shall be applied retrospectively to all periods 
presented with the cumulative effect of the change in accounting principle on periods prior to those presented 
recognized as of the beginning of the first period presented. Early adoption is not permitted. Management believes 
the adoption of FSP No. APB 14-1 will not have a material effect on its results of operations, financial position or 
cash flows.

Table of Contents 

     In June 2008, the FASB issued EITF Issue 07-5 “Determining whether an Instrument (or Embedded Feature) is 
indexed to an Entity’s Own Stock” (“EITF No. 07-5”). Paragraph 11(a) of SFAS 133 “Accounting for Derivatives 
and Hedging Activities” specifies that a contract that would otherwise meet the definition of a derivative but is both 
(a) indexed to the Company’s own stock and (b) classified in stockholders’ equity in the statement of financial 
position would not be considered a derivative financial instrument. EITF No. 07-5 provides a new two-step model to 
be applied in determining whether a financial instrument or an embedded feature is indexed to an issuer’s own stock 
and thus able to qualify for the SFAS 133 paragraph 11(a) scope exception. EITF No. 07-5 is effective for financial 
statements issued for fiscal years beginning after December 15, 2008, and interim periods within those fiscal years. 
Early application is not permitted. Management believes that the adoption of EITF No. 07-5 will not have a material 
effect on our results of operations, financial position or cash flows.

     As of December 31, 2007, the Company did not hold any available-for-sale securities. The Company’s available-
for-sale securities at December 31, 2008 consist principally of US agency securities, which are stated at fair value 
based on quoted prices for similar securities in active markets (Level 2 in the fair value hierarchy). The Company’s 
policy is to maintain a highly liquid short-term investment portfolio. Proceeds from the sales and maturities of 
available-for-sale securities amounted to approximately $126.9 million, $286.7 million, and $46.1 million for the 
years ended December 31, 2006, 2007, and 2008, respectively. Gross realized gains and losses for available-for-sale 
securities were insignificant for the years ended December 31, 2006, 2007, and 2008. Gross realized gains and losses 
for available-for-sale securities are recorded as other income (expense). The cost of securities sold is based on the 
specific identification method. Unrealized gains and losses for available-for-sale securities were not significant for 
the year ended December 31, 2007 and were $295,000 for the year ended December 31, 2008. Unrealized gains and 
losses are included in other comprehensive income (loss).  

4.  State research and development credit exchange receivable  

     The State of Connecticut provides certain companies with the opportunity to exchange certain research and 
development income tax credit carryforwards for cash in exchange for forgoing the carryforward of the research and 
development income tax credits. The program provides for an exchange of research and development income tax 
credits for cash equal to 65% of the value of corporation tax credit available for exchange. Estimated amounts 
receivable under the program are recorded as a reduction of research and development expenses. During the years 
ended December 31, 2006, 2007, and 2008, research and development expenses were offset by $0.6 million, 
$0.8 million, and $1.8 million, respectively, in connection with the program.

     Leasehold improvements are amortized over four years which is the shorter of the term of the lease or the service 
lives of the improvements. Depreciation and amortization expense related to property and equipment for the years 
ended December 31, 2006, 2007 and 2008, and the cumulative period from February 14, 1991 (date of inception) to 
December 31, 2008 was $8.5 million, $8.5 million, $11.8 million and $59.4 million, respectively. Capitalized interest 
during the years ended December 31, 2006, 2007 and 2008 was $0.1 million, $1.4 million and $2.5 million, 
respectively.  

     In December 2007, the Company determined that machinery being built for commercial manufacturing use would 
no longer be used for this purpose and had no other further alternative use other than for research related to 
AFRESA. Accordingly, the Company expensed to research and development the $5.0 million carrying value of the 
machinery previously included in construction in progress. Additionally, in November 2007, the Company initiated a 
plan to sell certain manufacturing machines. A charge in the amount of $1.6 million is reflected in the research and 
development expenses in the accompanying statement of operations for the year ended December 31, 2007 to write 
down the machines being held for sale to their estimated fair value of $1.6 million. The $1.6 million carrying value 
of the machines held for sale are included in the prepaid expenses and other current assets caption in the 
accompanying consolidated balance sheet as of December 31, 2007 and were sold in early 2008. In December 2008, 
the Company determined that software previously purchased would no longer be utilized, resulting in an impairment 
charge of $459,000.

     On August 2, 2006, the Company entered into a $150.0 million loan arrangement with its principal stockholder, 
which was amended on August 1, 2007 and replaced with a new loan arrangement on October 2, 2007. Under the 
new arrangement, the Company can borrow up to a total of $350.0 million before January 1, 2010. On February 26, 
2009, the promissory note underlying the loan arrangement was revised as a result of the principal stockholder being 
licensed as a finance lender under the California Finance Lenders Law. Accordingly, the lender was revised to The 
Mann Group LLC, or the Lender, an entity controlled by the Company’s principal stockholder. This new licensing 
also eliminated the draw restrictions under the previous loan arrangement and the Company is now able to borrow up 
to a total of $350.0 million from time to time with appropriate notice to the Lender. Interest will accrue on each 
outstanding advance at a fixed rate equal to the one-year LIBOR rate as reported by the Wall Street Journal on the 
date of such advance plus 3% per annum and will be payable quarterly in arrears. Principal repayment is due on 
December 31, 2011. At any time after January 1, 2010, the principal stockholder can require the Company to prepay 
up to $200.0 million in advances that have been outstanding for at least 12 months. If the principal stockholder 
exercises this right, the Company will have until the earlier of 180 days after the principal stockholder provides 
written notice or December 31, 2011 to prepay such advances. In the event of a default, all unpaid principal and 
interest either becomes immediately due and payable or may be accelerated at the principal stockholder’s option, and 
the interest rate will increase to the one-year LIBOR rate calculated on the date of the initial advance or in effect on 
the date of default, whichever is greater, plus 5% per annum. Any borrowings under the loan arrangement will be 
unsecured. The loan arrangement contains no financial covenants. There are no warrants associated with the loan 
arrangement, nor are advances convertible into the Company’s common stock.  

     Under the previous loan arrangement, the Company borrowed $50.0 million on August 2, 2006 and $20.0 million 
on November 27, 2006. On December 12, 2006, the Company paid off the total borrowings of $70.0 million 
following the completion of concurrent offerings of convertible notes and common stock.

     In July 2008, the Company requested an advance of up to $150.0 million. On December 29, 2008, the Company 
received an installment of $30.0 million against this advance. As of December 31, 2008, the amount outstanding 
under the arrangement was $30.0 million.  

8.  Senior convertible notes  

     On December 12, 2006, the Company completed an offering of $115.0 million aggregate principal amount of 
3.75% Senior Convertible Notes due 2013 (the “Notes”), including $15.0 million aggregate principal amount of the 
Notes sold pursuant to the underwriters’ over-allotment option that was exercised in full. The Notes are governed by 
the terms of an indenture dated as of November 1, 2006 and a First Supplemental Indenture, dated as of 
December 12, 2006. The Notes bear interest at the rate of 3.75% per year on the principal amount of the Notes, 
payable in cash semi-annually in arrears on June 15 and December 15 of each year, beginning June 15, 2007. The 
Company had accrued interest of $192,000 related to the Notes for the years ended December 31, 2007 and 2008. 
The Notes are general, unsecured, senior obligations of the Company and effectively rank junior in right of payment 
to all of the Company’s secured debt, to the extent of the value of the assets securing such debt, and to the debt and 
all other liabilities of the Company. The maturity date of the Notes is December 15, 2013 and payment is due in full 
on that date for unconverted securities. Holders may convert, at any time prior to the close of business on the 
business day immediately preceding the stated maturity date, any outstanding Notes into shares of the Company’s 
common stock at an initial conversion rate of 44.5002 shares per $1,000 principal amount of Notes, which is equal to 
a conversion price of approximately $22.47 per share, subject to adjustment. Except in certain circumstances, if the 
Company undergoes a fundamental change: (1) the Company will pay a make-whole premium on the Notes 
converted in connection with a fundamental change by increasing the conversion rate on such Notes, which amount, 
if any, will be based on the Company’s common stock price and the effective date of the fundamental change, and 
(2) each holder of the Notes will have the option to require the Company to repurchase all or any portion of such 
holder’s Notes at a repurchase price of 100% of the principal amount of the Notes to be repurchased plus accrued and 
unpaid interest, if any.  

     The Company incurred approximately $3.7 million in debt issuance costs which are recorded as an offset to the 
debt in the accompanying balance sheet. These costs are being amortized to interest expense using the effective 
interest method over the term of the Notes.  

9.  Common and preferred stock  

     Private Placements — On August 5, 2005, the Company closed a $175.0 million private placement of common 
stock and the concurrent issuance of warrants for the purchase of additional shares of common stock to accredited 
investors including the Company’s principal stockholder who purchased $87.3 million of the private placement. The 
Company sold 17,132,000 shares of common stock in the private placement, together with warrants to purchase up to 
3,426,000 shares of common stock at an exercise price of $12.228 per share which became exercisable on 
February 1, 2006 and expire on August 5, 2010. In connection with this private placement, the Company paid 
$4.5 million in commissions to the placement agents and incurred $300,000 in other offering expenses which resulted 
in net proceeds of approximately $170.2 million.  

     On October 2, 2007, the Company sold 15,940,489 shares of the Company’s common stock to its principal 
stockholder at a price per share of $9.41 and 11,074,197 million shares of common stock to other investors at a price 
per share of $9.03. The sales of common stock resulted in aggregate net proceeds to the Company of approximately 
$249.8 million after deducting offering expenses.  

     Public Equity Offering — On December 12, 2006, the Company closed the sale of 20,000,000 shares of its 
common stock at a public offering price of $17.42 per share and on December 19, 2006, closed the sale of an 
additional 3,000,000 shares of its common stock at a public offering price of $17.42 per share pursuant to an over-
allotment option granted to the underwriters of the offering. Approximately 5.8 million shares were sold to certain of 
the Company’s officers and directors, including 5.75 million shares sold to the principal stockholder. In connection 
with this offering, the Company paid approximately $15.0 million in underwriting fees and incurred approximately 
$1.1 million in other offering expenses which resulted in net proceeds of approximately $384.7 million.  

     Common Stock — In May 2007, the Company’s stockholders approved an increase in the Company’s authorized 
shares of common stock from 90,000,000 to 150,000,000. As of December 31, 2008, 102,008,096 shares of common 
stock are issued and outstanding.  

     The Company had reserved shares of common stock for issuance as follows:  

Exercise of common stock options
Conversion of senior convertible notes into common stock
Exercise of common stock warrants

together with warrants to purchase up to 2,882,873 shares of common stock, all of which were issued in the 
August 2005 private placement, expired. All of the warrants remained outstanding as of December 31, 2008.  

     As of December 31, 2006 the holders of 916,715 shares of the Company’s common stock and the holders of 
warrants to purchase 12,459 shares of the Company’s common stock had rights, subject to some conditions, to 
require the Company to file registration statements covering the resale of their shares or to include their shares in 
registration statements that the Company may file for itself or other stockholders. All such rights expired on 
December 1, 2007. Additionally, the warrants to purchase 12,459 shares of common stock all expired, unexercised 
on December 1, 2007.  

10.  Stock award plans  

     As of December 31, 2008, the Company has three active stock-based compensation plans — the 2004 Equity 
Incentive Plan (the “Plan”), the 2004 Non-Employee Directors’ Stock Option Plan (the “NED Plan”), and the 2004 
Employee Stock Purchase Plan (the “ESPP”). The Plan provides for the granting of stock awards including stock 
options and restricted stock units, to employees, directors and consultants. The NED Plan provides for the automatic, 
non-discretionary grant of options to the Company’s non-employee directors. Awards also remain outstanding at 
December 31, 2008 under the following inactive plans: the 1999 Stock Plan, the CTL Plan, and the Allecure Plan. 
There are also options outstanding to our principal stockholder at December 31, 2008 that were not granted under 
any plan; these options were granted during the year ended December 31, 2002, vested over four years, and have an 
exercise price of $25.23 per share. The following table summarizes information about our stock-based award plans as 
of December 31, 2008:

     The Company’s board of directors determines eligibility, vesting schedules and exercise prices for stock awards 
granted under the Plan. The NED Plan provides for automatic, non-discretionary grant of options to the Company’s 
non-employee directors. Options and other stock awards under the Plan and the NED Plan expire not more than ten 
years from the date of the grant and are exercisable upon vesting. Stock options generally vest over four years. 
Current stock option grants vest and become exercisable at the rate of 25% after one year and ratably on a monthly 
basis over a period of 36 months thereafter. Restricted stock units generally vest at a rate of 25% per year over four 
years with consideration satisfied by service to the Company. Certain performance-based awards vest upon achieving 
three pre-determined performance milestones which are expected to occur over periods ranging from 27 months to 
42 months from the date of grant. The Plan provides for full acceleration of vesting if an employee is terminated 
within thirteen months of a change in control, as defined.  

     On February 6, 2008, the Compensation Committee approved a management proposal designed to encourage 
employee retention. The proposal involved the issuance of restricted stock units to the majority of employees and 
executive officers of the Company. A total of 1,678,674 restricted stock units were granted under the 2004 Equity 
Incentive Plan. These units will remain unvested until June 30, 2009, at which point they will fully vest. Stock 
compensation expense associated with these grants will be recorded on a straight line basis from February 6, 2008 
through June 30, 2009 and is estimated to total approximately $11.0 million.  

     On May 22, 2008, the Company’s stockholders approved an amendment to the 2004 Equity Incentive Plan to 
increase the number of shares of common stock available for issuance under the plan by 5,000,000 shares.

     On July 9, 2008, the Company announced an Offer to Exchange Outstanding Options to Purchase Common Stock 
(the “Offer”) under which the Company offered eligible employees the opportunity to exchange up to an aggregate of 
5,417,840 shares underlying their out-of-the money stock options, on a grant by grant basis, for a reduced number of 
restricted stock units. The Offer expired on August 6, 2008. Pursuant to the Offer, the Company accepted for 
exchange options to purchase an aggregate of 4,493,509 shares of the Company’s common stock and issued 
restricted stock units covering an aggregate of 2,246,781 shares of the Company’s common stock. For the newly 
issued restricted stock units, both the remaining estimated unamortized stock compensation expense related to the 
exchanged options of approximately $13.9 million and the estimated incremental stock compensation expense 
resulting from the exchange of approximately $3.7 million will be amortized over the vesting periods of the newly 
issued restricted stock units.  

     In March 2004, the Company’s board of directors approved the 2004 Employee Stock Purchase Plan (“ESPP”), 
which became effective upon the closing of the Company’s initial public offering. Initially, the aggregate number of 
shares that could be sold under the plan was 2,000,000 shares of common stock. On January 1 of each year, for a 
period of ten years beginning January 1, 2005, the share reserve automatically increases by the lesser of: 700,000 
shares, 1% of the total number of shares of common stock outstanding on that date, or an amount as may be 
determined by the board of directors. However, under no event can the annual increase cause the total number of 
shares reserved under the ESPP to exceed 10% of the total number of shares of capital stock outstanding on 
December 31 of the prior year. On January 1, 2006, 2007, and 2008 the ESPP share reserve was increased by 
503,141, 700,000 and 700,000 shares, respectively. In November 2006, the Company’s board of directors approved a 
decrease of 2.6 million shares to the reserve in order to make additional shares available for the Company’s 
December 2006 offerings (see Note 1 — Description of Business and Basis of Presentation — Public Offerings). As 
of December 31, 2008, 977,488 shares were available for issuance under the ESPP. For the years ended 
December 31, 2006, 2007, and 2008 the Company sold 86,093, 124,011, and 349,317 shares, respectively, of its 
common stock to employees participating in the ESPP.  

     Upon adoption of FASB Statement No. 123R, the Company continues to account for non-employee stock-based 
compensation expense based on the estimated fair value of the options, determined using the Black-Scholes option 
valuation model, in accordance with EITF No. 96-18, and amortizes such expense on a straight-line basis. In 
November 2004, pursuant to assignment agreements with two consultants, the Company issued 200 shares of its 
common stock under its 2004 Equity Incentive Plan. The Company agreed to issue 99,800 additional shares upon the 
achievement of certain milestones specified in consulting agreements and for the year ended December 31, 2004, the 
Company recorded approximately $1.1 million in stock-based compensation expense related to these agreements. In 
November 2005, 39,800 of the 99,800 shares were issued to the consultants and the Company decreased stock-based 
compensation expense by approximately $146,000 based on the fair market value of the shares when issued. In 
September 2007, the next milestone was considered probable and the Company decreased stock compensation 
expense by approximately $115,000 based on the fair market value of the shares. In October 2007, the milestone was 
met and 30,000 shares were issued. In December 2007, the third milestone was considered probable of achievement 
and the Company recognized stock compensation expense of approximately $238,000. In January 2008, the final 
milestone was met and 30,000 shares were issued. As of December 31, 2008, there were 284,470 options outstanding 
to consultants.  

     During the years ended December 31, 2006, 2007, and 2008, the Company recorded stock-based compensation 
expense related to its stock award plans and the ESPP of $14.7 million, $17.6 million, and $24.8 million, 
respectively.

The Company uses the Black-Scholes option valuation model to estimate the grant date fair value of employee stock 
options. The expected life of the option is estimated using the “simplified” method as provided in SEC Staff 
Accounting Bulletin No. 107 (SAB No. 107). Under this method, the expected life equals the arithmetic average of 
the vesting term and the original contractual term of the options. The Company estimates volatility using the 
historical volatility of its stock. The Company has selected risk-free interest rates based on U.S. Treasury Securities 
with an equivalent expected term in effect on the date the options were granted. Additionally, the Company uses 
historical data and management judgment to estimate stock option exercise behavior and employee turnover rates to 
estimate the number of stock option awards that will eventually vest. The Company calculated the fair value of 
employee stock options for the years ended December 31, 2007 and 2008 using the following assumptions:

vesting period of 2.3 years.  

11. Warrants  

     During 1995 and 1996, the Company issued warrants to purchase shares of common stock. The warrants contain 
provisions for the adjustment of the exercise price and the number of shares issuable upon the exercise of the warrant 
in the event the Company declares any stock dividends or effects any stock split, reclassification or consolidation of 
its common stock. The warrants also contain a provision that provides for an adjustment to the exercise price and the 
number of shares issuable in the event that the Company issues securities for a per share price less than a specified 
price. As of December 31, 2004, warrants to purchase 131,628 shares of common stock were outstanding. During the 
second quarter ended June 30, 2005, warrants to purchase 110,888 shares of common stock were exchanged for 
24,210 shares of common stock resulting in stock-based compensation expense of $245,000 based on a fair market 
value of the common stock of $10.12 per share. Warrants to purchase 8,304 shares of common stock expired during 
2005. The remaining warrants to purchase 12,459 shares of common stock at a weighted average exercise price of 
$12.64 per share all expired unexercised on December 1, 2007.  

     In connection with the sale of common stock in the private placement which closed on August 5, 2005, the 
Company concurrently issued warrants to purchase up to 3,426,000 shares of common stock at an exercise price of 
$12.228 per share. See also Note 9 — Common and Preferred Stock — Private Placement. These warrants became 
exercisable on February 1, 2006 and expire in August 2010. During the year ended December 31, 2006, 
approximately 543,000 warrants were exercised and net settled for approximately 339,000 shares. As of 
December 31, 2008, warrants to purchase 2,882,873 shares of common stock remained outstanding. In connection 
with the sale of common stock in the public offering that closed on December 6, 2006, two holders of outstanding 
warrants to purchase a total of 1,710,091 shares of common stock agreed to amend the terms of their warrants to 
provide that such warrants would not be exercisable from December 6, 2006 until the date on which the Company 
has at least 100,000,000 shares of its common stock duly and validly authorized. In May 2007, the Company’s 
stockholders approved an increase in the Company’s authorized shares of common stock from 90,000,000 to 
150,000,000. As of December 31, 2008, all warrants were exercisable.

     Operating Leases — The Company leases certain facilities and equipment under various operating leases, which 
expire at various dates through 2013. Future minimum rental payments required under operating leases are as follows

     Rent expense under all operating leases for the years ended December 31, 2006, 2007 and 2008 was 
approximately, $1.3 million, $1.5 million, and $1.7 million, respectively.  

     Capital Leases — The Company’s capital leases were not material for the years ended December 31, 2006, 2007 
and 2008.  

     Supply Agreement — In November 2007, the Company entered into a long-term supply agreement with Organon 
N.V. (“Organon”) pursuant to which Organon will manufacture and supply specified quantities of recombinant 
human insulin. The initial term of this supply agreement will end on December 31, 2012 and can be automatically 
extended for consecutive two-year terms under specified circumstances. The Company has made annual purchase 
commitments through the initial term aggregating to approximately $104 million. These purchases are expected to be 
delivered from 2009 through 2012. If the Company terminates the supply agreement following failure to obtain or 
maintain regulatory approval of AFRESA or either party terminates the agreement following the parties’ inability to 
agree after any regulatory authority mandated changes to product specifications that relate specifically to the use of 
insulin in AFRESA, the Company will be required to pay Organon a specified termination fee if Organon is unable to 
sell certain quantities of insulin to other parties.  

     Guarantees and Indemnifications — In the ordinary course of its business, the Company makes certain 
indemnities, commitments and guarantees under which it may be required to make payments in relation to certain 
transactions. The Company, as permitted under Delaware law and in accordance with its Bylaws, indemnifies its 
officers and directors for certain events or occurrences, subject to certain limits, while the officer or director is or was 
serving at the Company’s request in such capacity. The term of the indemnification period is for the officer’s or 
director’s lifetime. The maximum amount of potential future indemnification is unlimited; however, the Company 
has a director and officer insurance policy that may enable it to recover a portion of any future amounts paid. The 
Company believes the fair value of these indemnification agreements is minimal. The Company has not recorded any 
liability for these indemnities in the accompanying consolidated balance sheets. However, the Company accrues for 
losses for any known contingent liability, including those that may arise from indemnification provisions, when 
future payment is probable. No such losses have been recorded to date.  

     Litigation — The Company is involved in various legal proceedings and other matters. In accordance with FASB 
Statement No. 5, Accounting for Contingencies, the Company would record a provision for a liability when it is both 
probable that a liability has been incurred and the amount of the loss can be reasonably estimated.  

     Licensing Arrangement — On October 12, 2006, the Company entered into an agreement with The Technion 
Research and Development Foundation Ltd. (“TRDF”), an Israeli corporation affiliated with the Technion-Israel 
Institute of Technology (the “Technion”) to license certain technology from TRDF and to collaborate with TRDF in 
the further research in and the development and commercialization of such technology. In exchange for the rights 
that the Company obtained under this agreement, the Company agreed to pay to TRDF aggregate license fees of 
$3.0 million and to issue to TRDF a total of 300,000 shares of the Company’s common stock. The license fees were 
to be paid and the shares issued in three equal installments. The first installment occurred on October 18, 2006. The 
second installment was paid on December 3, 2007. The third installment was scheduled to occur, subject to the 
accomplishment of certain milestones, on October 12, 2008. The Company had also agreed to pay royalties to TRDF 
with respect to sales of certain products that contain or use the licensed technology or are covered by patents 
included in the licensed technology or are discovered through the use of the licensed technology. The Company 
agreed to pay up to $6.0 million of the royalties in advance upon the receipt of specified regulatory approvals. The 
Company agreed to pay to TRDF specified percentages of any lump-sum sub-license payments that the Company 
received if it decided to sub-license the technology. The Company had also agreed to pay a total of $2.0 million to 
TRDF in three nearly equal installments to fund sponsored research to be conducted at TRDF by a team led by a 
faculty member at Technion. The initial sponsored research payment was made upon signing of the agreement. The 
second sponsored research payment occurred on December 3, 2007 and the third sponsored research payment was 
scheduled to occur, subject to the

accomplishment of certain milestones, on October 12, 2008. The Company had also agreed to retain the services of 
the Technion faculty member as a consultant, for which the Company agreed to pay the consultant $60,000 per year 
and granted the individual an option to purchase 60,000 shares of the Company’s common stock. Under the terms of 
the agreement, the Company issued 100,000 shares of common stock to TRDF on October 12, 2006 and 
November 29, 2007, respectively. Additionally, $1.6 million in license fees were paid on October 18, 2006 and 
December 3, 2007, respectively. In August of 2008, we ended our agreement with TRDF and made no further 
payments for licensing fees in 2008.  

13. Employee benefit plans  

     The Company administers a 401(k) Savings Retirement Plan (the “MannKind Retirement Plan”) for its 
employees. For the years ended December 31, 2006, 2007 and 2008, the Company contributed $567,000, $821,000 
and $914,000 respectively, to the MannKind Retirement Plan.  

14. Income taxes  

     Deferred income taxes reflect the tax effects of temporary differences between the carrying amounts of assets and 
liabilities for financial reporting and income tax purposes. A valuation allowance is established when uncertainty 
exists as to whether all or a portion of the net deferred tax assets will be realized. Components of the net deferred tax 
asset as of December 31, 2007 and 2008 are approximately as follows (in thousands):

     As required by FASB Statement No. 109, management of the Company has evaluated the positive and negative 
evidence bearing upon the realizability of its deferred tax assets. Management has concluded, in accordance with the 
applicable accounting standards, that it is more likely than not that the Company may not realize the benefit of its 
deferred tax assets. Accordingly, the net deferred tax assets have been fully reserved. Management reevaluates the 
positive and negative evidence on an annual basis. During the years ended December 31, 2006, 2007 and 2008, the 
change in the valuation allowance was $96.2 million, $135.4 million and $138.1 million respectively, for income 
taxes.  

     At December 31, 2008, the Company had federal and state net operating loss carryforwards of approximately 
$1.1 billion and $558.1 million available, respectively, to reduce future taxable income and which will expire at 
various dates beginning in 2009 and 2012, respectively. As a result of the Company’s initial public offering, an 
ownership change within the meaning of Internal Revenue Code Section 382 occurred in August 2004. As a result, 
federal net operating loss and credit carry forwards of approximately $216.0 million are subject to an annual use 
limitation of approximately $13.0 million. The annual limitation is cumulative and therefore, if not fully utilized in a 
year can be utilized in future years in addition to the Section 382 limitation for those years. The federal net operating 
losses generated subsequent to the Company’s initial public offering in August 2004 are currently not subject to

any such limitation as there have been no ownership changes since August 2004 within the meaning of Internal 
Revenue Code Section 382. At December 31, 2008, the Company had research and development credits of $44.9 
million that expire at various dates through 2029.  

     The Company has evaluated the impact of FIN 48 on its financial statements, which was effective beginning 
January 1, 2007. The evaluation of a tax position in accordance with FIN 48 is a two-step process. The first step is 
recognition: The enterprise determines whether it is more-likely-than-not that a tax position will be sustained upon 
examination, including resolution of any related appeals or litigation processes, based on the technical merits of the 
position. In evaluating whether a tax position has met the more-likely-than-not recognition threshold, the enterprise 
should presume that the position will be examined by the appropriate taxing authority that would have full 
knowledge of all relevant information. The second step is measurement: A tax position that meets the more-likely-
than-not recognition threshold is measured to determine the amount of benefit to recognize in the financial 
statements. The tax position is measured at the largest amount of benefit that is greater than 50 percent likely of 
being realized upon ultimate settlement. Tax positions that previously failed to meet the more-likely-than-not 
recognition threshold should be recognized in the first subsequent financial reporting period in which that threshold 
is met. Previously recognized tax positions that no longer meet the more-likely-than-not recognition threshold should 
be derecognized in the first subsequent financial reporting period in which that threshold is no longer met. The 
Company believes that its income tax filing positions and deductions will be sustained on audit and does not 
anticipate any adjustments that will result in a material change to its financial position. Therefore, no reserves for 
uncertain income tax positions have been recorded pursuant to FIN 48. The cumulative effect, if any, of applying 
FIN 48 is to be reported as an adjustment to the opening balance of retained earnings in the year of adoption. The 
Company did not record a cumulative effect adjustment related to the adoption of FIN 48. Tax years since 1992 
remain subject to examination by the major tax jurisdictions in which the Company is subject to tax.  

15. Related party transactions  

     During the year ended December 31, 2006 the principal stockholder purchased 5,750,000 shares of common stock 
at $17.42 per share in the Company’s December 2006 equity offering on terms identical to other purchasers resulting 
in proceeds of approximately $100.1 million to the Company. In connection with the equity offering the Company 
paid $280,000 in filing fees related to the principal stockholder’s filings made pursuant to the Hart-Scott-Rodino 
Antitrust Improvement Act of 1976. During the year ended December 31, 2006, the Company borrowed 
$70.0 million from its principal stockholder under the loan arrangement described in Note 7. On December 12, 2006, 
in connection with the completion of their equity and convertible debt offerings, the Company paid principal and 
interest of $70.0 million and $1.6 million, respectively, under the loan arrangement.  

     The Company issued 8,550,446 shares of its common stock to its principal stockholder during the year ended 
December 31, 2005 for proceeds of approximately $87.3 million. In connection with this issuance, the board of 
directors approved the issuance of warrants to purchase 1,710,091 shares of the Company’s common stock at 
$12.228 per share, which expire on August 2, 2010. The issuance of shares and warrants to the principal stockholder 
was on terms identical to the other purchasers in the private placement, as approved by the Company’s board of 
directors.  

     On October 2, 2007, the Company sold 15.9 million shares of the Company’s common stock to its principal 
stockholder at a price per share of $9.41 and 11.1 million shares of common stock to other investors at a price per 
share of $9.03. The sales of common stock resulted in aggregate net proceeds to the Company of approximately 
$249.8 million after deducting offering expenses. Also, on October 2, 2007, the Company entered into a new loan 
arrangement with its principal stockholder to borrow up to a total of $350.0 million before January 1, 2010. This new 
arrangement replaced the existing loan arrangement with its principal stockholder to borrow up to $150.0 million 
through August 1, 2008. On December 29, 2008, the Company borrowed $30.0 million under this agreement and had 
accrued interest of $12,000 for the year ended December 31, 2008. See Note 7 — Related-Party Loan Arrangement.  

     Alfred E. Mann, who is the Company’s principal stockholder and chief executive officer, has established the 
Alfred Mann Institute for Biomedical Development at the Technion (“AMI-Technion”) to expedite the translation of 
intellectual property and technology of the Technion into commercial medical products for the public benefit. Over a 
period of several years, Mr. Mann will establish a $100 million endowment for AMI-Technion. Mr. Mann does not 
directly or indirectly have any interest in TRDF (see Note 12 — Commitments and Contingencies — Licensing 
Arrangement).  

     In connection with certain meetings of the Company’s board of directors and on other occasions when the 
Company’s business necessitated air travel for the Company’s principal stockholder and other Company employees, 
the Company utilized the principal stockholder’s private aircraft, and the Company paid the charter company that 
manages the aircraft on behalf of the Company’s majority stockholder approximately $212,000, $105,090, and 
$130,000, respectively, for the years ended December 31, 2006, 2007

and 2008 on the basis of the corresponding cost of commercial airfare. These payments were approved by the audit 
committee of the board of directors.  

     Heather Hay Murren, a member of our board of directors in 2008, is the Cofounder, Chair and Chief Executive 
Officer of Nevada Cancer Institute, a nonprofit organization. Nevada Cancer Institute is currently conducting a 
clinical trial for the Company through a clinical research organization and was paid approximately $10,000 and

PROMISSORY NOTE  

Exhibit 10.1

Dated February 26, 2009
Valencia, California

FOR VALUE RECEIVED, MANNKIND CORPORATION, a Delaware corporation (“Borrower”), hereby promises to pay to the order of THE MANN 
GROUP LLC (“Lender”), in lawful money of the United States of America and in immediately available funds, the principal sum of up to 
Three Hundred and Fifty Million Dollars ($350,000,000) or the aggregate principal amount of all Advances (as defined below) made 
hereunder, whichever is less (the “Loan”) together with accrued and unpaid interest thereon, each due and payable on the dates and in the 
manner set forth below.  

     1. Principal Repayment. The outstanding principal amount of each Advance together with all accrued and unpaid interest thereon shall be 
due and payable on December 31, 2011 (the “Maturity Date”).  

     2. Interest Rate. Borrower further promises to pay interest on the outstanding principal amount of each Advance from the date thereof until 
payment in full, which interest shall be payable at a rate equal to the one year London Interbank Offered Rate (LIBOR) reported by the Wall 
Street Journal (or a comparable periodical if such periodical is no longer published) on the day of such Advance plus 3% per annum, or the 
maximum rate permissible by law (which under the laws of the State of California shall be deemed to be the laws relating to permissible rates 
of interest on commercial loans), whichever is less. Interest shall be due and payable quarterly in arrears not later than the first day of each 
calendar quarter for the preceding quarter, commencing on the first day of the calendar quarter following the calendar quarter in which an 
Advance is made, and shall be calculated on the basis of a 365/366-day year for the actual number of days elapsed.  

     3. Place of Payment. All amounts payable hereunder shall be payable in lawful money of the United States of America at the office of 
Lender, 28903 North Avenue Paine, Valencia, CA 91355, unless another place of payment shall be specified in writing by Lender.  

     4. Application of Payments; Prepayment.  

          4.1 Payment on this Note shall be applied first to accrued interest, and thereafter to the outstanding principal balance hereof.  

          4.2 This Note may be prepaid in whole or in part without penalty or premium. Any amount prepaid pursuant to this Section 4.2 may be 
reborrowed subject to Section 5 hereof. Any partial prepayment made pursuant to this Section 4.2 shall be applied to interest first and then to 
principal, and shall be applied to the oldest outstanding Advance first. At the time of any prepayment of principal hereunder, Borrower shall 
also pay all accrued and unpaid interest on the amount prepaid through the date of prepayment.  

          4.3 At any time after January 1, 2010, upon delivery of prior written notice (the “Call Notice”), Lender may require Borrower to prepay 
Advances that have been outstanding for more than twelve months as of the date of the notice. Lender may  

  
  
 
not require Borrower to prepay Advances in an aggregate amount exceeding $200,000,000 pursuant to this Section 4.3. If Lender exercises 
such call right, Borrower shall, on the earlier of: (x) 180 days after delivery of the Call Notice or (y) the Maturity Date, prepay the Advances in 
the amount set forth in the Call Notice. Any partial prepayment made pursuant to this Section 4.3 shall be applied to interest first and then to 
principal. At the time of any prepayment of principal hereunder, Borrower shall also pay all accrued and unpaid interest on the amount prepaid 
through the date of prepayment.  

     5. Loan Requests. Provided that no Event of Default has occurred and is continuing, from and after the date hereof and through and 
including December 31, 2011, Lender shall make available to Borrower for borrowings by Borrower from time to time a principal amount of 
Three Hundred and Fifty Million Dollars ($350,000,000) less the aggregate principal amount of the Advances outstanding on the date hereof 
(each, an “Advance”). Whenever Borrower desires an Advance hereunder, Borrower shall notify Lender by facsimile with a transmission 
confirmation or by electronic mail as long as a read receipt is requested and received no later than 4:00 p.m. Pacific time, sixty (60) calendar 
days prior to the date on which the Advance is requested to be made. At the time of any Advance (or at the time of receipt of any payment of 
principal), Lender shall make or cause to be made, an appropriate notation on the Exhibit A attached hereto reflecting the amount of such 
Advance (or the amount of such payment). The outstanding amount of this Note set forth on such Exhibit A shall be prima facie evidence of 
the principal amount thereof outstanding, but the failure to record, or any error in so recording, shall not limit or otherwise affect the 
obligations of Borrower to make payments of principal of or interest on this Note when due.  

     6. Representations and Warranties. The Borrower hereby represents and warrants to the Lender as follows:  

          6.1 The Borrower has the requisite power and authority to enter into this Note and to consummate the transactions contemplated hereby. 
The execution and delivery of this Note by the Borrower and the consummation by the Borrower of the transactions contemplated hereby have 
been duly authorized by all necessary corporate action on the part of the Borrower. This Note has been duly executed and delivered by the 
Borrower and constitutes the legal, valid and binding agreement of the Borrower enforceable against the Borrower in accordance with its terms, 
except as may be limited by (i) applicable bankruptcy, insolvency, reorganization, moratorium and other laws of general application affecting 
enforcement of creditors’ rights generally and (ii) equitable principles of general applicability relating to the availability of specific 
performance, injunctive relief or other equitable remedies.  

          6.2 No consent, approval, authorization, order, license, registration or qualification of or with any Governmental Entity is required for the 
execution and delivery by the Borrower of this Note or the transactions contemplated hereby, except such consents, approvals, authorizations, 
orders, licenses, registrations or qualifications as have been obtained, or which, if not obtained, would not, individually or in the aggregate, 
have a material adverse effect on the ability of the Borrower to perform its obligations hereunder or consummate the transactions contemplated 
hereby on a timely basis. As used in this Note, the term “Governmental Entity” means any agency, bureau,  

                                   
  
commission, authority, department, official, political subdivision, tribunal or other instrumentality of any government, whether (i) regulatory, 
administrative or otherwise (including, without limitation, a self-regulatory organization or stock exchange); (ii) federal, state or local; or 
(iii) domestic or foreign.  

          6.3 The execution and delivery by the Borrower of this Note, the performance by the Borrower of its obligations hereunder, and the 
consummation by the Borrower of the transactions contemplated hereby, will not conflict with or result in a breach or violation of (i) any of the 
terms or provisions of, or constitute a default (or an event which with notice or lapse of time or both would become a default) under, or give to 
others any rights of termination, amendment, acceleration or cancellation of, any indenture, mortgage, deed of trust, loan agreement or other 
agreement or instrument to which the Borrower or any of its subsidiaries is a party or by which the Borrower or any of its subsidiaries is bound 
or to which any of their property or assets is subject or (ii) any applicable law or statute or any order, rule or regulation of any Governmental 
Entity having jurisdiction over the Borrower or any of its subsidiaries or any of their respective properties, except for in the case of either 
clause (i) or (ii) such conflicts, breaches or violations that would not prevent or delay the consummation of the transactions contemplated by 
this Note or that would not be reasonably expected to have a material adverse effect on the Borrower, nor will any such action result in any 
violation of the provisions of the organizational documents of the Borrower.  

     7. Default. Each of the following events shall be an “Event of Default” hereunder:  

          (a) Borrower fails to pay timely any of the principal amount due under this Note or any accrued interest or other amounts due under this 
Note on the date the same becomes due and payable or within five (5) business days thereafter;  

          (b) Borrower files any petition or action for relief under any bankruptcy, reorganization, insolvency or moratorium law or any other law 
for the relief of, or relating to, debtors, now or hereafter in effect, or makes any assignment for the benefit of creditors or takes any corporate 
action in furtherance of any of the foregoing;  

          (c) An involuntary petition is filed against Borrower (unless such petition is dismissed or discharged within sixty (60) days) under any 
bankruptcy statute now or hereafter in effect, or a custodian, receiver, trustee, assignee for the benefit of creditors (or other similar official) is 
appointed to take possession, custody or control of any property of Borrower; or  

          (d) Any representation or warranty made herein or in any other document delivered in connection herewith shall be incorrect or 
misleading in any material respect when made or deemed made (except where any such representation or warranty by the terms thereof is 
subject to a materiality standard, in which case such representation or warranty shall be incorrect or misleading in any respect).  

Upon the occurrence of an Event of Default hereunder, all unpaid principal, accrued interest and other amounts owing hereunder shall, at the 
option of Lender, and, in the  

                                   
  
case of an Event of Default pursuant to (b) or (c) above, automatically, be immediately due, payable and collectible by Lender pursuant to 
applicable law, the commitment of the Lender to lend shall, at the option of the Lender, and in the case of an Event of Default pursuant to (b) 
or (c) above, automatically, terminate, and the interest rate applicable to outstanding Advances upon an Event of Default shall increase to 
LIBOR calculated on the date of the initial Advance or the date of the Event of Default (whichever is greater) plus 5% per annum for the period 
after said Event of Default until payment, or the maximum rate permissible by law as defined above, whichever is less.  

     8. Waiver. Borrower waives presentment and demand for payment, notice of dishonor, protest and notice of protest of this Note, and shall 
pay all costs of collection when incurred, including, without limitation, reasonable attorneys’ fees, costs and other expenses.  

The right to plead any and all statutes of limitations as a defense to any demands hereunder is hereby waived to the full extent permitted by 
law.  

     9. Governing Law. This Note shall be governed by, and construed and enforced in accordance with, the laws of the State of New York, 
excluding conflict of laws principles that would cause the application of laws of any other jurisdiction. Borrower consents to in personam 
jurisdiction of the courts in the State of New York sitting in New York County and of the United States District Court of the Southern District 
of New York for any legal action or proceeding with respect to this Note. Borrower, by execution and delivery of this Note, hereby irrevocably 
accepts in respect of its property, generally and unconditionally, the jurisdiction of the aforesaid courts.  

     10. Successors and Assigns. This Note shall be binding upon and inure to the benefit of the Borrower and Lender and their respective 
successors and assigns; provided that the Borrower may not assign or otherwise transfer any of its rights or obligations hereunder without the 
prior written consent of the Lender. Lender may assign to one or more other persons all or a portion of its rights (but not its obligations) under 
this Note with respect to all or a portion of the Advances made by it  

     11. Integration. This Note reflects the entire understanding of the parties with respect to the transactions contemplated hereby and shall not 
be contradicted or qualified by any other agreement or instrument, oral or written, before or after the date hereof.  

     12. Amendments, Modification, Etc. No amendment, modification or waiver of any provision of this Note, and no consent to any 
departure by Lender or Borrower and their assigns therefrom, shall in any event be effective unless the same shall be in writing and signed by 
the Lender and Borrower, and then such waiver or consent shall be effective only in the specific instance and for the specific purpose for which 
given.  

     13. No Waiver. No failure on the part of the Lender to exercise, and no delay in exercising, any right hereunder shall operate as a waiver 
thereof; nor shall any single or partial exercise of any right under this Note preclude any other or further exercise thereof or the exercise of any 
other right. The rights of the Lender under this Note against Borrower are not conditional or contingent on any attempt by the Lender to 
exercise any of its rights under this Note against Borrower or any other person.  

                                   
  
     14. Expenses. The Borrower agrees to reimburse, periodically and upon request, and at the date of effectiveness of this Note or upon 
termination of this Note, (i) the Lender’s reasonable expenses, including the reasonable fees and disbursements of the Lender’s attorneys, 
arising in connection with the preparation, negotiation, execution, delivery, amendment and administration of this Note and related transactions 
and (ii) the Lender’s expenses, including the fees and disbursements of the Lender’s attorneys, in connection with the enforcement of this Note 
or the protection of the Lender’s rights under this Note. In addition, the Borrower agrees to reimburse the Lender for all reasonable expenses, 
including the reasonable fees and disbursements of the Lender’s attorneys, incurred in connection with the licensing of the Lender as a finance 
lender under the California Finance Lenders Law.  

     15. Indemnity. The Borrower shall indemnify, defend and hold harmless the Lender and its agents and attorneys (collectively, the 
“Indemnitees”) from and against (i) any and all transfer taxes, documentary taxes, assessments or charges made by any Governmental Entity 
by reason of the execution and delivery of this Note or the making of the Advances, and (ii) any and all liabilities, losses, damages, penalties, 
judgments, claims, costs and expenses of any kind or nature whatsoever (including reasonable attorneys’ fees, and disbursements in connection 
with any actual or threatened investigative, administrative or judicial proceeding, whether or not such Indemnitee shall be designated a party 
thereto) that may be imposed on, incurred by or asserted against such Indemnitee, in any manner relating to or arising out of this Note, the 
Advances or the use or intended use of the proceeds of the Advances; provided that no Indemnitee shall have the right to be indemnified or 
held harmless hereunder for its own gross negligence or willful misconduct, as determined by a final judgment of a court of competent 
jurisdiction.  

     16. Seniority. Amounts due under this Note shall rank pari passu with all of the Borrower’s other senior unsecured obligations, including 
the Borrower’s 3.75% Senior Convertible Notes due 2013.
