Item 1.     Business  

Business Overview  

Insmed Incorporated is a biopharmaceutical company focused on the development and commercialization of drugs to treat metabolic 

diseases and endocrine disorders within niche markets that have unmet medical needs. Currently, our development and commercial activities 
involve drugs that modulate Insulin-like Growth Factor-1, IGF-1, activity in the human body. Our lead product, IPLEX™ (mecasermin 
rinfabate [rDNA origin] injection), is the only FDA approved, once-daily IGF-1 replacement therapy. IPLEX was approved in December 2005 
for the treatment of growth failure in children with severe primary IGF-1 deficiency or with growth hormone gene deletion who have 
developed neutralizing antibodies to growth hormone (Severe Primary IGFD). As an Orphan Drug, IPLEX is entitled to seven years of 
marketing exclusivity for IPLEX in the treatment of Severe Primary IGFD in the United States. We are conducting and plan to pursue further 
clinical trials in order to expand the label for IPLEX into additional clinical indications.  

We are building our own specialty sales force to launch IPLEX in the United States in the second quarter of this year. We believe we can 
effectively market IPLEX by targeting the top 400 pediatric endocrinologists in the United States who we estimate treat the substantial majority 
of the approximately 6,000 children who suffer from severe short stature due to Severe Primary IGFD. The positive therapeutic characteristics 
of IPLEX that we believe will make it a commercial success are:  

• 

• 

• 

• 

   IPLEX has demonstrated statistically significant increases in linear growth. 

   IPLEX is the only once-daily IGF-1 replacement therapy approved for use in the United States. 

   IPLEX may be administered either in the morning or evening. 

   IPLEX has demonstrated an acceptable safety profile. 

We believe the commercial opportunities for IPLEX are significant and reach beyond our approved indication of Severe Primary IGFD. 

Subject to completion of additional clinical studies and regulatory approval, the initial approval of IPLEX may offer us an opportunity for label 
expansion into other indications, most with larger patient populations than Severe Primary IGFD. We are currently conducting Phase II clinical 
studies in patients with myotonic muscular dystrophy, HIV associated adipose redistribution syndrome and extreme insulin resistance. We also 
intend to conduct additional clinical studies in other growth disorders associated with IGF-1 deficiency.  

We also intend to expand the market for IPLEX by pursuing approvals outside of the United States, including the European Union. We 
have been granted Orphan Drug Designation by the European Medicines Agency for the Evaluation of Medicinal Products, or the EMEA, for 
IPLEX in the treatment of primary growth hormone insensitivity syndrome (Laron Syndrome) or GHIS. We intend to expand this designation 
to include Severe Primary IGFD should this approval be granted by the EMEA. Should approval of IPLEX be granted for this indication by the 
EMEA, as an Orphan Drug, IPLEX will be provided up to 10 years of marketing exclusivity in the European Union. We plan to file for 
marketing authorization with the EMEA in the third quarter of 2006.  

In addition to our IPLEX development and commercialization programs, we have an oncology program focused on two compounds, 

INSM-18 and rhIGFBP-3. Our longer-term development efforts are primarily focused on the potential to treat cancers by using these 
compounds to target growth factors and their receptors. Our small molecule compound, INSM-18, has novel effects on the activity of the IGF-1 
and other receptors, such as Her2/Neu, and may lead to the inhibition of growth of various tumors. A Phase I/II clinical study of INSM-18 in 
refractory prostate cancer patients has been initiated at the University of California, San Francisco School of Medicine. rhIGFBP-3 is a 
naturally occurring anti-tumor agent normally found in the human bloodstream. Several epidemiological studies have demonstrated that cancer 
risk increases as levels of rhIGFBP-3 in the blood decrease. A Phase I clinical study to evaluate rhIGFBP-3 safety and tolerance in human 
volunteers is in progress.

Our Business Strategy  

We intend to capitalize on the therapeutic opportunities presented by IPLEX by commercializing it in its approved indication in the 

United States and extending the use of IPLEX in other indications and other geographic markets. We also intend to develop, seek regulatory 
approval of and commercialize other drugs for the treatment of other metabolic diseases and endocrine disorders with unmet medical needs. 
This includes the development of cancer treatments based on our expertise in IGF-1 biology. Both the INSM-18 and rhIGFBP-3 development 
programs are based on the belief that these product candidates modulate the over expression of IGF-1 and its receptors in solid tumors. Key 
elements of our strategy include:  

Launch IPLEX commercially in 2006 with our own specialty sales force. We are building a sales and marketing force to target 
approximately 400 U.S.-based pediatric endocrinologists who we estimate treat the substantial majority of the children with Severe Primary 
IGFD. These physicians are readily accessible because they are primarily hospital-based and located in major metropolitan areas. We have 
hired a management team for our sales, marketing, medical communications and managed care groups that will bring IPLEX to the market. By 
the end of 2006, we expect to employ 25 to 30 sales representatives. In addition, we intend to conduct continuing medical education programs, 
medical symposia, and regional speaker programs aimed at establishing awareness of IPLEX in the medical community.  

Develop IPLEX in additional non-growth disorder indications. We intend to initiate clinical studies of IPLEX in the United States in 

additional indications where existing preclinical or clinical data suggest IPLEX may be an effective treatment. We have initiated studies in 
myotonic muscular dystrophy (estimated U.S. patient population is 40,000), HIV associated adipose redistribution syndrome (estimated U.S. 
patient population is 80,000) and extreme insulin resistance.  

Expand the Severe Primary IGFD indication to other growth disorders related to IGF-1 deficiency. There are a number of growth 

disorders related to IGF-1 deficiency other than Severe Primary IGFD which represent conditions with significant unmet medical needs and 
significant opportunities for expansion of the market for IPLEX. We plan to investigate these other indications and further develop those that 
provide the best market opportunity for label expansion. We believe that successful label expansion studies in IGF-1-related short stature may 
expand the U.S. market for IPLEX from 6,000 children to approximately 30,000 children. We intend to initiate a Phase II study in children 
with Noonan Syndrome, a population with IGF-1 deficiency, in the second quarter of this year.  

Establish a commercialization strategy for IPLEX outside the United States. We will either build our own European sales and 
marketing team or explore opportunities to partner with an established sales and marketing organization in Europe. We intend to file a 
Marketing Authorization Application, or MAA, with the EMEA for approval of IPLEX in the European Union for the treatment of an 
indication that is very similar to the indication for which we recently received approval from the FDA in the United States. We also intend to 
seek regulatory marketing authorization of IPLEX in additional territories, including Israel and certain Middle Eastern states and South 
America.  

Develop Oncology Portfolio. We will continue to conduct clinical studies of INSM-18 and rhIGFBP-3 for the treatment of cancer. Based 

on the results of these studies, we will evaluate opportunities to initiate Phase II clinical studies in one or more of the following cancer types: 
breast, colorectal, lung or prostate. We will either conduct additional studies independently or enter into development or licensing agreements 
with companies with greater expertise in the development of cancer therapies.

IPLEX  

IPLEX is our proprietary drug for the delivery of recombinant insulin-like growth factor 1 (IGF-1). It is administered as a preformed 

complex with a recombinant form of its natural binding protein, insulin-like growth factor binding protein 3 (rhIGFBP-3). This novel 
compound is administered as a once-daily subcutaneous injection, which can restore and maintain IGF-1 levels to physiologically relevant 
levels. The binding protein, rhIGFBP-3, extends the residence time of IGF-1 in the blood, mimicking normal human physiology. In the bound 
state, we believe IGF-1 is inactive, and remains so until delivered to target tissues in the body where it is released and becomes biologically 
active.  

IPLEX’s Approved Indication  

Growth Failure Due to Severe Primary IGFD. Severe primary IGF-1 deficiency or Severe Primary IGFD is a condition which causes 
growth failure and extreme short stature due to a marked deficiency in IGF-1. This deficiency can be due to hereditary defects in the growth 
hormone receptor or post-receptor pathway, or due to acquired causes such as growth hormone antibodies in patients with growth hormone 
gene deletion. Characteristics of this condition can include:  

• 

• 

• 

• 

• 

• 

   normal or elevated serum growth hormone levels; 

   inability to generate normal IGF-1 levels after growth hormone provocation; 

   reduced serum IGF-1 and rhIGFBP-3 levels; 

   severe postnatal growth failure and markedly reduced adult height; 

   truncal adiposity; and 

   delayed skeletal maturation. 

Physicians characterize a child’s height deficit by calculating a height standard deviation score, or height SDS, which indicates how many 

standard deviations a child’s height is from the average value for the normal population of the same age and sex. The American Academy of 
Pediatrics and the American Academy of Clinical Endocrinology define short stature as a height that is more than two standard deviations 
below the average. Children with Severe Primary IGFD have a height SDS that is at least three standard deviations below the average. Children 
with Severe Primary IGFD who are untreated will typically attain a final height of no more than approximately 5’1” (155 cm) for boys and 4’9 
 1 / 2 ” (146 cm) for girls. Historically, prior to the approval of an IGF-1 therapy, the only treatment for severe short stature has been human 
growth hormone (hGH). However, it has been long recognized that there are a significant group of children who do not adequately respond to 
hGH due to growth hormone insensitivity.

Table of Contents  

Approximately 380,000 children in the United States are referred each year to pediatric endocrinologists for evaluation of possible short 

stature. We believe approximately 6,000 of these children suffer from Severe Primary IGFD and may be treated with IPLEX.  

We are preparing to commercially launch IPLEX with our own sales force in the United States in the second quarter of 2006. In addition, 

we are currently assessing our regulatory strategy regarding submission of a Marketing Authorization Application, with the European 
Medicines Evaluation Agency for IPLEX treatment of Severe Primary IGFD. We intend to file our MAA in Europe by the end of the third 
quarter of 2006.  

Ongoing Clinical Trial  

We have results from an ongoing Phase III study of 47 children with Severe Primary IGFD. Twenty-six of these 47 children completed at 
least 6 months of IPLEX replacement therapy and were evaluable for efficacy at 6 months, which is the generally accepted minimum length of 
time required to adequately measure growth response to drug therapy. A statistically significant increase in average growth rate from 3.4 cm 
per year prior to treatment to 7.4 cm per year during the first 6 months of IPLEX treatment was demonstrated in the lower dose group, where as 
the increase was from 2.2 cm per year to 8.8 cm per year in the higher dose group (p<0.0001 for both groups). A p-value of less than 0.0001 
means that the probability that this result occurred by chance was less than 1 in 10,000. A probability of 5 in 100 or less, or p<0.05, is 
commonly considered to be statistically significant. With this six-month data, IPLEX was approved for marketing by the FDA on 
December 12, 2005.  

Twenty-four of the subjects have received at least 12 months of treatment and qualified for inclusion in the 12 month analysis. These 

subjects experienced a statistically significant increase in growth rate from 3.4 to 6.4 cm/year and 2.0 to 8.3 cm/year over the 12 month 
treatment period in the low and high dose groups, respectively (p<0.0001 for both groups). Although three patients left the study before 
completion, none of the 47 patients discontinued IPLEX treatment due to adverse events considered related to drug. Some patients experienced 
hypoglycemia, or low blood glucose levels. Enlargement of the tonsils and headaches were also noted in some patients.  

We believe that increases in growth rates resulting from IPLEX treatment were clinically meaningful, leading to catch-up growth as 
indicated by a significant increase in height SDS. These results are comparable to those observed in clinical studies of other approved growth 
indications for other growth-promoting therapies.  

Other Indications for IPLEX in Development  

Myotonic Muscular Dystrophy. Myotonic muscular dystrophy or MMD (also known as myotonic dystrophy, dystrophia myotonica or 

Steinert’s disease) is the most common type of adult muscular dystrophy and affects approximately 1 in 8,000 individuals. MMD causes 
progressive muscle wasting and weakness in the hands, forearms, legs, neck and face. It often involves many other systemic effects, including 
endocrine abnormalities, especially with respect to insulin, a regulator of blood sugar (glucose); neurological changes, including excessive 
sleepiness and apathy; cataracts, usually requiring surgical excision; gastrointestinal problems; and cardiac rhythm abnormalities, often 
requiring pacemaker insertion. In extreme cases, these patients can eventually become totally disabled, dying usually from respiratory or 
cardiac failure. At present, there is no treatment to reverse most of these symptoms. Previous preclinical and human studies have demonstrated 
that IGF-1 therapy may be an effective treatment for myotonic muscular dystrophy.  

Based on information published by the Muscular Dystrophy Association, we believe that there are approximately 40,000 patients that 

suffer from MMD in the United States.  

Ongoing Clinical Study  

A Phase II clinical study program investigating IPLEX as a treatment for MMD has been initiated by the University of Rochester School 

of Medicine, with funding provided by the Muscular Dystrophy Association and  

7  

   
Table of Contents  

the National Institute of Health. This Phase II program is designed to investigate the safety and tolerability of once-daily subcutaneous 
injections of IPLEX in patients with MMD using two sequential studies each involving 15 patients. The first study is a 24-week, dose-
escalation study of IPLEX intended to identify an optimal dose for the subsequent 24-week, fixed-dose study. Both studies will evaluate a 
number of safety parameters in a prospective manner, as well as several key efficacy measures such as muscle mass and strength.  

The University of Rochester has been designated by the National Institutes of Health (NIH) as one of several “centers of excellence” for 

muscular dystrophy research. As such, the University of Rochester is eligible to receive funding from the NIH and Muscular Dystrophy 
Association. A portion of this funding is being used to substantially fund this clinical study.  

HIV Associated Adipose Redistribution Syndrome (HARS). HIV-associated adipose redistribution syndrome, or HARS, is characterized 

by fat maldistribution in HIV-infected patients. Patients with HARS experience abnormal, pathological accumulation of adipose tissue in the 
trunk, primarily in the form of visceral adipose tissue located deep within the abdomen, underneath the abdominal muscle wall. This fat 
accumulation may be present with or without fat depletion, lipoatrophy, and/or metabolic abnormalities. In general, HARS patients accumulate 
excess visceral adipose tissue in the abdomen or may develop a fat pad on the upper back commonly known as a “buffalo hump.” This 
condition is sometimes referred to as HIV Lipodystrophy.  

Since the advent of highly active antiretroviral therapy, or HAART, there has been a marked increase in adverse metabolic effects in HIV 

patients on antiretroviral treatments. These adverse effects include insulin resistance, hyperglycemia, dyslipidemia and changes in body fat 
distribution that include syndromes of both central fat accumulation (visceral adiposity and buffalo hump) and fat loss in the limbs. Recent 
studies performed in subjects on HAART suggest that at least 20% of individuals develop the morphologic features of this syndrome. With the 
similarity of HARS to metabolic syndrome X, which has been associated with increased risk of cardiovascular disease, it is now feared that 
these HAART side effects may impact the long-term prognosis in patients whose life expectancies have been significantly extended due to 
effective viral suppression by HAART. At present, there is no approved treatment for this condition.  

We believe that there are at least 80,000 patients who suffer from HARS in the United States.  

Ongoing Clinical Study  

A Phase II clinical study investigating IPLEX as a treatment for HARS has been initiated by the University of California, San Francisco. 

This Phase II open-label study is designed to evaluate the safety and efficacy of 12 weeks of IPLEX treatment in 12 subjects with HARS. To 
qualify for inclusion in the study, patients must be between 18-65 years of age, have confirmed HIV-1 infection and fat accumulation (visceral 
adiposity). The primary goal of the study is to determine the effects of IPLEX on visceral fat and glucose and lipid metabolism.  

Extreme Insulin Resistance. Syndromes of extreme insulin resistance result from genetic defects in the insulin receptor or insulin 

signaling pathways and include Type A and Type B Syndromes, Rabson-Mendenhall Syndrome and Leprechaunism. In addition to insulin 
resistance and glucose intolerance or overt diabetes, these syndromes share a number of common features, including variable degrees of 
hyperandrogenism, hirsutism, and dysmorphic features. Individuals with extreme insulin resistance who develop frank diabetes require large 
doses (>200 units/day) of subcutaneous insulin, oral hypoglycemic agents and insulin sensitizers. Despite this intense regimen, glycemic 
control remains poor and these patients are at high risk of the complications of diabetes such as cardiovascular disease, nephropathy, 
retinopathy and neuropathy. Previous Phase II clinical studies completed with IPLEX in diabetic patients have shown improved glycemic 
control, improved insulin sensitivity as well as a reduction in daily insulin consumption. IPLEX has been granted Orphan Drug Designation in 
both the United States and Europe for extreme insulin resistance.

Table of Contents  

Ongoing Clinical Study  

We have initiated a Phase II clinical study at the University of Cambridge to investigate the therapeutic benefit of treating Type A and 
Rabson-Mendenhall Syndrome extreme insulin resistance with IPLEX. This Phase II, open-label, dose-ranging study is designed to evaluate 
the safety and efficacy of 16 weeks of IPLEX treatment in 10 patients with Type A extreme insulin resistance or Rabson-Mendenhall 
Syndrome. To qualify for inclusion in the study, patients must be between 10-65 years of age and have a diagnosis of Type A extreme insulin 
resistance or Rabson-Mendenhall Syndrome. The primary efficacy endpoints of the trial are improvement in glycemic control, improvement in 
insulin sensitivity, reduction in hemoglobin A1c and improvement in body composition. We expect to present interim data at Endocrine 
Society’s Annual Meeting in June 2006 (ENDO 2006), and complete the trial by the end of 2006.  

Noonan Syndrome. Noonan Syndrome is a congenital disorder characterized by a deficiency in IGF-1, short stature, heart defects and 

variable dysmorphic features. Growth failure is a consistent feature of Noonan Syndrome and the response to recombinant human growth 
hormone therapy has been disappointing, particularly in children with an identified gene mutation.  

With an incidence of approximately one in 2,000, we estimate that there are approximately 30,000 children in the United States with 

Noonan Syndrome.  

Planned Clinical Study  

We plan to conduct a Phase II, open-label, multicenter, clinical study to evaluate the pharmacokinetics, safety and efficacy of 12 months 

of IPLEX treatment in 24 children with growth failure due to Noonan Syndrome. The IPLEX dose will be titrated to maintain IGF-I SDS in the 
upper normal range. The primary and secondary efficacy measures are annualized height velocity and height SDS, respectively.  

Long-Term Development Opportunity for IPLEX  

Diabetes. As an extension of studies related to extreme insulin resistance and as one of our longer-term development initiatives, we 

believe that IPLEX may have application in the treatment of diabetes.  

Data from several Phase II studies conducted with IPLEX indicate that IPLEX has a beneficial effect in lowering glucose levels, and 
insulin demands. Patients with type 1 diabetes are characterized by their inability to produce insulin. In these patients, insulin deficiency leads 
to glucose intolerance in childhood. In type 1 diabetes, down-regulation of growth hormone receptors in the liver results in reduced circulating 
IGF-1 levels, which can lead to growth hormone hypersecretion. This, in turn, causes decreased insulin sensitivity and worsening of metabolic 
control. We believe treatment of type 1 diabetes with IPLEX may reduce growth hormone levels and improve insulin sensitivity and glycemic 
control, while decreasing insulin dose requirements. Type 2 diabetes is characterized by insulin resistance. In addition to low circulating levels 
of IGF-1, these patients have an increased number of insulin/IGF-1 hybrid receptors. Increased expression of these hybrid receptors positively 
correlates with a decrease in both insulin binding affinity and insulin sensitivity. We believe treatment of type 2 diabetics requiring insulin 
therapy with IPLEX may lead to improved glycemic control while decreasing the insulin dose requirement.  

According to the ADA, approximately 73% of insulin-using type 2 diabetes patients are not adequately controlling their blood sugar 

levels to the ADA recommended guidelines. We believe that there are approximately one million insulin-using diabetes patients who do not 
adequately control their blood sugar. Since clinical studies for this indication are likely to be very large and expensive, we have no current 
plans to pursue a clinical development program on our own, however, we may look for a partner to assist us with this clinical development 
program.

Oncology Programs — INSM-18 and rhIGFBP-3  

INSM-18 and rhIGFBP-3 are in early clinical development and are primarily being investigated for the treatment of cancer. Identification 

of the signaling pathways that regulate tumor growth has led to novel strategies for the treatment of cancer. As a result, new agents that target 
growth factors and their receptors are emerging as promising new alternatives to existing treatments which generally include cytotoxic agents 
that significantly decrease patient quality of life. To this end, we believe both INSM-18 and rhIGFBP-3, are promising potential novel 
treatments for a variety of cancer types. Preclinical models demonstrate that both treatments interact with the IGF system to reduce tumor 
growth.  

INSM-18  

INSM-18 is an orally available small molecule tyrosine kinase inhibitor that has demonstrated selective inhibition of IGF-1 and human 

epidermal growth factor receptor (Her2/Neu). It has demonstrated anti-tumor activity in preclinical studies of breast, lung, pancreatic and 
prostate tumors. Two single dose Phase I clinical studies have been previously completed with INSM-18. In both studies, INSM-18 was safe 
and well tolerated.  

The American Cancer Society estimated that 232,000 new cases of prostate cancer occurred in the United States in 2005. It was also 
estimated by the American Cancer Society that 30,350 deaths occurred as a result of prostate cancer, making it the second leading cause of 
cancer death in men.  

Ongoing Clinical Study  

The University of California, San Francisco, has initiated a dose-escalating Phase I/II clinical study designed to define the maximum 

tolerated dose of INSM-18 in patients with relapsed prostate cancer. The study will consist of a 28-day extension at each dose level to 
investigate the effect of INSM-18 on prostate-specific antigen levels.  

rhIGFBP-3  

Although IGF-1 is critical for normal growth and metabolism, aberrant signaling through this pathway is closely linked to the abnormal 
and unregulated growth of a variety of tumors. Blocking tumor-associated IGF signaling has been proven to prevent tumor growth in a variety 
of preclinical models. rhIGFBP-3 has demonstrated preclinical efficacy in numerous cancer indications, including breast, prostate, liver, 
ovarian, and colon cancers. Additionally, several lines of recent evidence from various cell systems have suggested that rhIGFBP-3 may play a 
more active, IGF-1-independent role in growth regulation of cancer cells, binding specifically with high affinity to the surface of various cell 
types and directly inhibiting monolayer growth of these cells in an IGF-1-independent manner. Recent independent studies have demonstrated 
that when IGFBP-3 is used in combination it can accentuate and even synergize the efficacy of standard cancer therapies. Paclitaxel-induced 
apoptosis is accentuated by rhIGFBP-3, which has been shown to sensitize cells to apoptotic signals such as irradiation and ceramides. 
Preclinical in vitro and in vivo studies performed by us corroborate previously published reports regarding rhIGFBP-3’s efficacy when 
administered alone or in combination therapy.  

Ongoing Clinical Trial  

We have initiated a Phase I clinical study with rhIGFBP-3. The Phase I clinical study is an open-label, dose-escalation study designed to 

evaluate the safety, tolerability and pharmacokinetics of a single intravenous dose of rhIGFBP-3. The primary goal of this 30-patient study is to 
identify the appropriate dose of rhIGFBP-3 for a planned Phase II clinical trial in breast cancer.  

Research and Development  

We have devoted substantially all of our resources since we began our operations to the research and development of a number of drug 
candidates for metabolic and endocrine diseases. Our research and development efforts are now principally focused on conducting additional 
clinical studies, further developing our  

10  

   
Table of Contents  

approved drug, IPLEX, and expanding the label for IPLEX into other indications. We conduct very little of our own preclinical laboratory 
research. We are currently conducting a worldwide Phase III clinical study with our lead drug, IPLEX, and we are also conducting clinical 
studies with our anti-cancer drug candidates, INSM-18 and rhIGFBP-3 and plan on conducting additional clinical studies with these drugs in 
the future.  

Research and development expenses primarily include expenses incurred in preparing and obtaining the approval from regulatory bodies, 

certain expenses involving the development of manufacturing processes and clinical studies (including necessary quantities of drugs being 
studied). Our research and development expenses were approximately $23.3 million in 2004 and $21.8 million for the year ended 
December 31, 2005. The amount spent on research and development relative to the overall budget is expected to decrease now that we are 
dedicating a greater proportion of our resources to the commercialization of IPLEX.  

Manufacturing  

We currently manufacture our own supply of bulk IPLEX and rhIGFBP-3 at our FDA approved facility in Boulder, Colorado. The 

manufacturing process requires compliance with current good manufacturing practices, or cGMP, and other similar regulations. IPLEX is a 
complex of two proteins, rhIGF-1 and its binding protein rhIGFBP-3, and is manufactured using recombinant DNA technology. The 
manufacturing process is complicated and involves expression of the two proteins by bacterial fermentation followed by purification and 
combination of the two proteins. During the manufacturing process, rhIGF-1 and rhIGFBP-3 are produced separately and then combined to 
make IPLEX. The rhIGFBP-3 can either be utilized to make IPLEX or kept separate as its own distinct product. We currently outsource to third 
party contract manufacturers some of the analytical testing and the final fill, finish and labeling of IPLEX.  

As part of ongoing regulatory compliance, it is likely that the FDA will inspect our manufacturing facilities and our contract 

manufacturers’ facilities from time to time to ensure compliance with cGMP. If these facilities are not in compliance with cGMP, the FDA will 
likely require us to halt manufacturing until we bring the facilities into compliance. This could take a substantial period of time and could 
adversely affect the development and timing of our clinical studies and/or commercial sales of IPLEX. If for any other reason we are unable 
manufacture sufficient quantities of our drug candidates and their components which meet our planned time and cost parameters, the 
commercialization of IPLEX and the development and timing of our clinical studies for additional indications may be adversely affected.  

We expect to expend significant resources for the expansion and modification of our manufacturing facility over the next three years in an 

effort to increase our production capacity and the efficiency of our operations. We believe this facility will meet our commercial and clinical 
needs for at least the next three years.  

Marketing and Sales  

Our sales and marketing efforts will initially target the sale of IPLEX to patients being treated by the approximately 400 U.S.-based 
pediatric endocrinologists who we estimate treat the substantial majority of children with Severe Primary IGFD. Because these pediatric 
endocrinologists are primarily hospital-based and concentrated in major metropolitan areas, we believe that a focused marketing organization 
and specialized sales force can effectively serve them. In addition, we intend to conduct continuing medical education programs, medical 
symposia, and regional speaker programs aimed at establishing awareness of IPLEX in the physician community. We also intend to conduct 
post-marketing studies and establish a patient registry to provide further data on the safety and efficacy of IPLEX.  

The marketing and selling of IPLEX will be accomplished with an initial group of approximately 25-30 sales professionals with 
supporting staff in marketing, medical communications and managed care. In total, we expect the commercial operations group will grow to 
40-45 people by the end of 2006. Future expansion will largely be driven by the availability of new clinical data and FDA action on future 
marketing label expansion applications for IPLEX and our other leading drug candidates.  

11  

   
Table of Contents  

It is our belief that we can serve the top prescribing pediatric endocrinologists with a focused sales and marketing effort. We plan to 
launch IPLEX in the second quarter of this year and begin generating prescriptions for treating Severe Primary IGFD at that time. We will 
distribute IPLEX through an established specialty distributor. Like other high value protein therapeutics, revenues for IPLEX will be recorded 
with the initiation of each individual prescription. We believe this should allow the company to establish a long-term revenue stream as each 
patient is expected to remain on IPLEX for an average of 6-10 years. We are currently determining the pricing of IPLEX but anticipate pricing 
IPLEX within the range of the other currently marketed growth promoting agents.  

We are exploring several opportunities for sales and marketing in Europe, including the establishment of our own sales and marketing 

organization, acquisition of an existing sales and marketing organization and partnering with an established sales and marketing organization.  

Our goal is to retain marketing, sales and distribution rights to our drug candidates for certain niche markets and find commercial partners 

to develop and market our drugs in markets outside of our current focus.  

Patents and Proprietary Rights  

Insmed Patent Portfolio  

Proprietary protection is important to our business, and our policy is to protect our technology by filing patent applications for technology 

that we consider important. We intend to file additional patent applications, when appropriate, relating to improvements in our technology and 
other specific drugs that we develop. As with any pending patent application, there can be no assurance that any of these applications will issue 
in the United States or a foreign country. There also can be no assurance that a subsequent U.S. or foreign patent will later be held valid and 
enforceable.  

We hold 28 United States patents relating to the composition, production, antibodies and methods of use for IPLEX and rhIGFBP-3, 

including:  

• 

• 

   Two issued patents for rhIGFBP-3 composition-of-matter; 

   15 therapeutic use patents for IPLEX, IGF-1, rhIGFBP-3 or rhIGFBP-3 fragments for the treatment of various disease conditions; 

and 

• 

   11 patents regarding novel expression, production or analysis methods, some of which may be used for the manufacture of IPLEX 

and pharmaceutical compositions of IPLEX. 

As part of the ongoing development of IPLEX, INSM-18 and rhIGFBP-3, we have filed or intend to file patent applications related to 
new production methods, improved formulations, new medical uses and new dosing regimens in the United States and in many of the major 
international pharmaceutical markets. The various issued patents related to IPLEX and rhIGFBP-3 compositions, methods of production and 
methods of treatment expire at various times during the years 2010 through 2019.  

In addition, foreign counterparts to the above-referenced U.S. patents have issued or are pending issue in the major pharmaceutical 

markets, such as Europe, Canada and Japan.  

With respect to Europe, we recently decided to withdraw one of our patents, EP 451,194, or the ‘194 patent, which is directed to 
compositions and methods of using IGFBP-3. This patent expires in 2009. We do not believe that a competitor is developing IGFBP-3 or will 
engage in activities encompassed by this patent prior to 2009. As such, the costs of maintaining this patent outweigh its estimated value. 
Therefore, we have withdrawn its approval of the text of the ‘194 patent. As a result of this action, we expect the European Patent Office will 
soon revoke the ‘194 patent.  

12  

   
   
   
   
  
  
  
Table of Contents  

As part of our business strategy, we plan to license intellectual property which we feel may be important to the development and 
commercialization of our products. In April 2005, we were granted a non-exclusive license to certain proprietary manufacturing technology 
from Avecia Limited. In January 2004, we were granted a non-exclusive license to patent rights pertaining to the use of IGF-1 therapy for the 
treatment of extreme or severe insulin resistant diabetes from Fujisawa Pharmaceutical Co., Ltd. In November 1998, we were granted a non-
exclusive license to certain proprietary manufacturing technology from Brookhaven Science Associates, LLC.  

Reflecting our commitment to safeguarding proprietary information, we require our employees and consultants to sign confidentiality 
agreements. These agreements prohibit unauthorized disclosure of our proprietary information. Despite our efforts to protect our proprietary 
information, unauthorized parties may attempt to obtain and use our proprietary information. Policing unauthorized use of our proprietary 
information is difficult and the steps we have taken might not prevent misappropriation, particularly in foreign countries where the laws may 
not protect our proprietary rights as fully as do the laws of the United States.  

We note that there has been increasing litigation in the biopharmaceutical industry with respect to the manufacture and sale of new 
therapeutic compounds. The validity and breadth of claims in biotechnology patents may involve complex factual and legal issues, for which 
no consistent policy exists. In particular, the patent protection available for protein-based drugs, such as IPLEX and rhIGFBP-3, is highly 
uncertain and involves issues relating to the scope of protection of claims to gene sequences and the production of their corresponding proteins. 

Our patent positions are highly uncertain, and any future patents we receive for our potential products will be subject to this uncertainty, 

which may adversely affect our business, financial condition and results of operations. We intend to actively pursue patent protection for 
products resulting from our research and development activities that have significant potential commercial value. Nevertheless, it is possible 
that, in the patent application process, certain claims may be rejected or achieve such limited allowance that the value of the patents would be 
diminished. Further, there can be no assurance that any patents obtained will afford us adequate protection. In addition, any patents we procure 
may require cooperation with companies holding related patents. We may have difficulty forming a successful relationship with these other 
companies.  

In some cases, litigation or other proceedings may be necessary to enforce our patents or protect our know-how or other intellectual 

property rights. Any additional potential litigation is likely to result in a substantial cost to us and a diversion of our resources. We cannot be 
sure that any of our patents will ultimately be held valid. An adverse outcome in any litigation or proceeding could subject us to significant 
liability.  

Third-Party Patents  

Third parties, including Genentech, Inc. hold United States and/or foreign patents possibly directed to the composition, production and/or 
use of rhIGF-1, rhIGFBP-3, rhIGF-1/rhIGFBP-3 (IPLEX) and/or recombinant proteins. In addition, Novartis AG and Chiron Corporation have 
rights to United States and foreign patents relating to the use of IGF-1 for the treatment of type 1 diabetes, and Novartis owns United States and 
foreign patents relating to the treatment of osteoporosis with IGF-1. Furthermore, Genentech owns U.S. and foreign patents directed to using 
IGF-1 to increase the growth rate of certain patients with non-growth hormone-deficient short stature and patients having partial growth 
hormone insensitivity syndrome.  

We can provide no assurance that one of these third parties will not assert an infringement action against us. Likewise, we cannot predict 

with certainty the outcome of such a proceeding. In the event of a successful claim against us for infringement or misappropriation of a third 
party’s proprietary rights, we may be required to:  

• 

• 

   pay damages, including up to treble damages and the other party’s attorneys’ fees, which may be substantial; 

   cease the development, manufacture, marketing and sale of products that infringe the proprietary rights of others; 

13  

   
   
   
  
  
Table of Contents  

• 

   expend significant resources to redesign our product so that it does not infringe the proprietary rights of others, or to develop or 
acquire non-infringing proprietary rights, which may not be possible and would require additional clinical trials and regulatory 
approvals; 

• 

   redesign our product to avoid infringing on third party proprietary rights, which may result in significant regulatory delays associated 

with conducting additional clinical trials or other steps to obtain regulatory approval; and 

• 

   obtain one or more licenses from third parties for the infringed proprietary rights, which may not be available to us on acceptable 

terms or at all. 

Furthermore, litigation with any third party, even if the allegations are without merit, would likely be expensive and time-consuming and divert 
management’s attention.  

Any conclusions regarding non-infringement and invalidity are based in part on a review of publicly available databases and other 

information. There may be information not available to or otherwise not reviewed by us that might change our conclusions. Moreover, the 
scope and validity of patent claims are determined based on many facts and circumstances, and in a litigation a court may reach a different 
conclusion on any given patent claim than the conclusions that we have reached.  

We are currently defending infringement claims brought against us. On December 20, 2004, Tercica and Genentech filed a complaint 

against Avecia Limited and us in the United Kingdom at the High Court of Justice, Chancery Division, Patents Court alleging infringement of 
EP patent No. 571,417, or the ‘417 patent. The ‘417 patent has claims directed to particular uses of a combination of IGFBP-3 and IGF-1. In 
the complaint, Tercica asked the court for an injunction to restrain allegedly infringing activity, for a declaration that the ‘417 patent is valid 
and infringed, for an order requiring the delivery or destruction of allegedly infringing articles and materials and for an inquiry into possible 
economic damages. In May 2005, we filed for summary judgment to dismiss the complaint. Our motion for summary judgment was denied and 
a trial date in this litigation has not been set.  

In addition, on December 23, 2004, Genentech and Tercica sued us for infringement of U.S. Patent Nos. 5,187,151 and 6,331,414 in the 
United States District Court for the Northern District of California. These patents are directed to certain methods of using IGF-1/IGFBP-3 and 
methods of producing human IGF-1, respectively. On February 16, 2005, Tercica filed an amended complaint, adding an infringement 
allegation against us with respect to U.S. Patent No. 5,528,287, or the ‘287 patent. The claims of the ‘287 patent are directed to DNA encoding 
BP53 (i.e. IGFBP-3) and recombinant constructs, transformed host cells and methods for using same. Genentech and Tercica claim that the 
production or use of IPLEX, a complex of rhIGF-1/rhIGFBP-3, will infringe these patents. We moved to dismiss the amended complaint for 
lack of jurisdiction and on other grounds. At a hearing on the motion on April 15, 2005, the court granted our motion and dismissed the case 
with leave for plaintiffs to refile the complaint. A second amended complaint was filed on April 22, 2005 by Genentech and Tercica against us. 
Among other things, this amended complaint added Celtrix Pharmaceuticals, our wholly-owned subsidiary, as a defendant. We moved to 
dismiss the portion of the second amended complaint that relates to the ‘287 patent. On June 29, 2005, the Court denied our motion to dismiss. 
On July 14, 2005, we filed its answer and counterclaims. In the answer and counterclaims, we denied infringement and sought a declaratory 
judgment that the asserted patents are not infringed, are invalid, and/or are unenforceable. The reply to the counterclaims by Genentech and 
Tercica was filed on August 5, 2005. On October 17, 2005, Tercica and Genentech filed a third amended complaint adding Insmed Therapeutic 
Proteins, our wholly-owned subsidiary, as a defendant. The answer and counterclaims in response to the third amended complaint were filed by 
us on October 27, 2005. Briefing on patent claim construction issues and summary judgment motions is set to be completed by May 5, 2006, 
with a claim construction hearing scheduled for May 19, 2006. Discovery is ongoing and a trial date is scheduled for November 2006.  

On May 27, 2005, Genentech and Tercica filed a motion for preliminary injunction seeking an order barring us, until trial, from making, 

using or selling the drug called “SomatoKine,” (now known as IPLEX) with respect  

14  

   
   
   
  
  
  
Table of Contents  

to its allegations of infringement of U.S. Patent Nos. 6,331,414 and 5,187,151, and requesting that we be required to share any Orphan Drug 
Exclusivity it obtains with Tercica. We filed an opposition to the motion for a Preliminary Injunction on June 10, 2005. On June 16, 2005, 
Genentech and Tercica withdrew their motion for a preliminary injunction, but reserved the right to refile the motion for a preliminary 
injunction.  

We cannot predict with certainty the outcome of proceedings involving Tercica and Genentech. The claim construction ruling and 
summary judgment rulings to be issued by the court could have an adverse impact on our position in this proceeding, including by narrowing or 
limiting our defenses. An adverse ruling after trial on any of the claims alleged would have a material adverse effect on our business, financial 
condition and results of operations.  

We have entered into license agreements, and may enter into future license agreements, with various licensees to develop and market our 
drugs, and we can give no assurances that third parties will not claim that we and/or our licensees, by practicing our technology, are infringing 
on their proprietary rights. If other companies successfully bring legal actions against us or our licensees claiming patent or other intellectual 
property infringements, in addition to any potential liability for damages, a court could require us and/or our licensees to obtain a license in 
order to continue to use the affected processes or to manufacture or use the affected drugs, or alternatively, require us and/or our licensees to 
cease using such drugs or processes. Such a result may have an adverse effect on our business, financial condition and results of operations. 
Any such claim, with or without merit, could result in costly litigation or might require us and/or our licensees to enter into royalty or licensing 
agreements, all of which could delay or otherwise adversely impact the development of our potential drugs candidates for commercial use. If a 
court requires us to obtain licenses, there can be no assurance that we and/or our licensees will be able to obtain them on commercially 
favorable terms, if at all. Without such licenses, we and/or our licensees may be unable to develop certain drugs. Our breach of an existing 
license or our failure to obtain, or our delay in obtaining, a license to any technology that we require to commercialize our drugs may materially 
adversely impact our business, financial condition and results of operations.  

Competition  

We are engaged in an industry that is intensely competitive and characterized by rapid technological progress. For our approved drug, 

IPLEX, and our other drug candidates, we face significant competition from biotechnology, large pharmaceutical and other companies, as well 
as universities and research institutions. Most of these companies and institutions have substantially greater capital resources, research and 
development staffs, facilities and experience in conducting clinical studies and obtaining regulatory approvals. In addition, many of these 
companies have greater experience and expertise than we do in manufacturing and marketing pharmaceutical products.  

We cannot predict the relative competitive position of our drug candidates if they are approved for use. However, we expect that the 

following factors will determine our ability to compete effectively: safety and efficacy, product price, ease of administration, and marketing 
and sales capability.  

Competition for IPLEX  

Currently, we are aware of at least one other company, Tercica, that is selling a drug that competes directly with IPLEX. Tercica received 

approval from the FDA in August 2005 for its twice-daily IGF-1 injection drug, Increlex™, for the long-term treatment of growth failure in 
children with Severe Primary IGFD or with growth hormone gene deletion who have developed neutralizing antibodies to growth hormone. 
This indication is substantially similar to the indication for which the FDA approved IPLEX. It is likely that Tercica is planning to develop 
rhIGF-1 for some of the same indications that we plan to pursue with IPLEX. We are currently engaged in litigation with Tercica related to 
patent infringement, deceptive promotional statements and unfair business practices claims that Tercica has brought against us.  

15  

   
Table of Contents  

We believe that IPLEX has the following positive therapeutic attributes:  

• 

• 

• 

• 

   IPLEX has demonstrated statistically significant increases in linear growth. 

   IPLEX is the only once-daily IGF-1 replacement approved for use in the United States. 

   IPLEX may be administered either in the morning or evening. 

   IPLEX has demonstrated an acceptable safety profile. 

Growth hormone may also be a competitive product for the treatment of some indications that we may pursue with IPLEX, such as HIV 

associated adipose redistribution syndrome. The major suppliers of commercially available growth hormone are Genentech, Eli Lilly, Novo 
Nordisk, Pfizer and Serono. We believe that Novo Nordisk may be conducting clinical studies for the use of its growth hormone in pediatric 
IGF-1 deficiency. We are also aware that Serono is seeking regulatory approval for its growth hormone, Serostim™, for the treatment of HIV 
associated adipose redistribution syndrome, and that Theratechnologies is conducting Phase III studies for a growth hormone releasing agonist 
for the treatment of HIV associated adipose redistribution syndrome.  

In addition, we believe that Genentech, Merck, Novo Nordisk and Pfizer have previously conducted research and development of orally-

available small molecules that cause the release of growth hormone, known as growth hormone secretagogues. We are not aware of any 
continued clinical development of these molecules by these companies. We believe that Rejuvenon Corporation may have licensed certain 
rights to Novo Nordisk’s growth hormone secretagogues, which are in preclinical development. We are also aware that Theratechnologies is 
developing various peptides that stimulate the release of hormones that could be used in the treatment of some of the same indications we plan 
to pursue with IPLEX.  

Many companies are seeking to develop products and therapies for the treatment of diabetes. Our competitors include multinational 

pharmaceutical companies, specialized biotechnology firms, and universities and other research institutions. Our largest competitors include 
Amylin Pharmaceuticals, Bristol-Myers Squibb Company, Eli Lilly, GlaxoSmithKline, Merck, Novartis, Novo Nordisk and Takeda Chemical 
Industries. Various products are currently available to treat type 2 diabetes, such as injectable insulin, inhalable insulin, GLP-1 analogues and 
oral hypoglycemic drugs.  

Further, several companies are developing various new approaches to improve the treatments of type 1 and type 2 diabetes. Specifically, 

Amylin Pharmaceuticals has conducted and is continuing to conduct clinical studies for three products, Symlin, Byetta, and a long-acting 
release formulation of Byetta, for the treatment of type 2 diabetes. Symlin and Byetta were recently approved for use by the FDA. Tercica has 
indicated that it plans to pursue the development of rhIGF-1 in the treatment of severe forms of diabetes.  

Competition for Our Other Drug Candidates  

Many companies are pursuing the development of products for the treatment of cancer. Our competitors include multinational 

pharmaceutical companies, specialized biotechnology firms, and universities and other research institutions. Although we are unaware of any 
companies developing rhIGFBP-3 for cancer, we are aware of companies who are developing products that are intended to target the same 
IGF-1 pathway targeted by INSM-18 and rhIGFBP-3. These companies include ImClone, Amgen, OSI Pharmaceuticals, Bristol-Myers Squibb 
and Genentech.  

It is possible that there are other companies with products currently in development or that exist on the market that may compete directly 

with IPLEX, INSM-18 and rhIGFBP-3.  

Deceptive Promotional Statements and Unfair Business Practice Litigation  

On December 6, 2005, Tercica filed a complaint against us in the United States District Court for the Northern District of California 

alleging we made deceptive promotional statements and engaged in unfair  

16  

   
   
   
   
   
  
  
  
  
Table of Contents  

business practices related to Tercica’s product, Increlex, allegedly in violation of the California Business and Professions Code and the Federal 
Lanham Act. Tercica amended the complaint on December 15, 2005. Tercica is requesting injunctive and monetary relief.  

Although we deny any liability, no assurances can be given as to the outcome of this action. An unfavorable settlement or decision could 
affect our ability to make, use or sell our products, and would have a material adverse effect on our business, financial condition and results of 
operations. Any liability resulting from this action may exceed our financial resources. We have requested that the court dismiss the action on a 
number of bases, including that Tercica failed to state a claim under the Federal Lanham Act and the court lacks personal jurisdiction over us. 
We plan to seek attorneys’ fees from Tercica if the case is successfully concluded.  

Government Regulation  

Government authorities in the United States and other countries extensively regulate the research, development, testing, manufacture, 

promotion, marketing and distribution of drug products. If we do not comply with applicable requirements, we may be fined, the government 
may refuse to approve our marketing applications or allow us to manufacture or market our products, and we may be criminally prosecuted.  

We and our third party manufacturers may also be subject to regulations under other federal, state, and local laws, including the 

Occupational Safety and Health Act, the Environmental Protection Act, the Clean Air Act and import, export and customs regulations.  

FDA Approval Process  

The steps ordinarily required before a new drug may be marketed in the United States are similar to steps required in many other 
countries. The process required by the FDA before a new drug may be marketed in the United States generally involves the following: 
completion of preclinical laboratory and animal testing in compliance with FDA regulations, submission of an Investigational New Drug 
Application, or IND, which must become effective before human clinical studies may begin, performance of adequate and well-controlled 
human clinical studies to establish the safety and efficacy of the proposed drug for its intended use, and submission and approval of a New 
Drug Application, or NDA, by the FDA.  

Preclinical tests include laboratory evaluation of product chemistry and stability, as well as animal studies to evaluate toxicity before a 
drug is administered to human subjects. The results of preclinical testing are submitted to the FDA as part of an IND. The FDA requires a 30-
day waiting period after the submission of each IND before beginning clinical tests in humans. At any time during this 30-day period or at any 
time thereafter, the FDA may order the partial, temporary or permanent discontinuation of a clinical trial or impose other sanctions if the FDA 
believes that the clinical trial is not being conducted in accordance with FDA requirements or presents an unacceptable risk to the clinical trial 
patients. Clinical studies must be conducted in accordance with the FDA’s good clinical practices requirements. The IND process may become 
extremely costly and substantially delay development of our products. Moreover, positive results of preclinical tests will not necessarily 
indicate positive results in clinical studies.  

Clinical studies to support NDA approval are typically conducted in three sequential phases, but the phases may overlap. In Phase I 
clinical studies, the product is tested in a small number of patients or healthy volunteers, primarily for safety at one or more doses and to assess 
pharmacokinetics. In Phase II clinical studies, in addition to safety, the sponsor evaluates the efficacy of the product on targeted indications, 
identifies possible adverse effects and safety risks in a patient population, and assesses dose tolerance and optimal dose range. If a compound is 
found to be potentially effective and to have an acceptable safety profile in Phase II studies, Phase III studies, also referred to as “pivotal 
studies,” are undertaken. Phase III clinical studies typically involve testing for safety and clinical efficacy in an expanded patient population at 
geographically-dispersed study sites.  

17

After completion of the required clinical testing, an NDA is submitted. An NDA contains the results of the preclinical and clinical 

studies, together with, among other things, detailed information on the manufacture and composition of the product and proposed labeling, 
including payment of a user fee. The FDA may request additional information before accepting an NDA for filing, in which case the 
application must be resubmitted with the additional information. During its review of an NDA, the FDA may refer the application to an 
appropriate advisory committee for review, evaluation and recommendation as to whether the application should be approved. The FDA is not 
bound by the recommendation of an advisory committee.  

Under the policies agreed to by the FDA under the Prescription Drug User Fee Act, or the PDUFA. Once the NDA is accepted for filing 
by the FDA, the FDA has 10 months in which to complete its initial review of a standard NDA and respond to the applicant, and 6 months to 
initially review and respond to a priority NDA. Standard NDA status or priority NDA status are based on several factors identified by the FDA 
including for example, whether the drug product, if approved, would be a significant improvement compared to marketed products in the 
treatment, diagnosis, or prevention of a disease. The review process and the PDUFA goal date may be extended by 3 months if the FDA 
requests, or the NDA sponsor otherwise submits, a major amendment containing additional information or clarification regarding information 
already provided in the submission within the last 3 months of the PDUFA goal date.  

If the FDA’s evaluation of the NDA, and the FDA inspections of the clinical investigators and the facilities are favorable, the FDA may 
issue either an approval letter or an approvable letter. An approvable letter contains the conditions that must be met in order to secure approval 
of the NDA. If and when those conditions have been met to the FDA’s satisfaction, the FDA will issue an approval letter. An approvable letter 
authorizes commercial marketing of the drug for certain approved indications. In addition, an approval letter may contain various post-
marketing commitments or agreements, which are often referred to as Phase IV studies. If the FDA’s evaluation of the NDA submission, 
clinical investigation, or manufacturing facilities is not favorable, the FDA may refuse to approve the NDA and issue a not approvable letter.  

The manufacturers of approved products and their manufacturing facilities are subject to continual review and periodic inspections. 
Because we may contract with third parties for manufacturing of our products, our ability to control compliance with FDA requirements may 
be incomplete. In addition, after any of our drugs are on the market, identification of certain side effects or the occurrence of manufacturing 
problems could cause product recall, withdrawal of approval, reformulation of the drug, additional preclinical testing or clinical studies, or 
labeling changes.  

The FDA’s policies may change, and additional government regulations may be enacted that could prevent or delay regulatory approval 
of our products. 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.  

The Hatch-Waxman Act  

The Drug Price Competition and Patent Term Restoration Act of 1984 or Hatch-Waxman Act amended the Federal Food, Drug, and 

Cosmetic Act. Under the Hatch-Waxman Act, newly-approved drugs and indications may benefit from a statutory period of non-patent 
marketing exclusivity. The Hatch-Waxman Act provides 5-year marketing exclusivity to the first applicant to gain approval of an NDA for a 
new chemical entity, meaning that the FDA has not previously approved any other new drug containing the same active moiety. However, in 
the case of a combination drug containing a new chemical entity and a non-new chemical entity, 5-year exclusivity does not attach to the new 
chemical entity. The Hatch-Waxman Act prohibits the submission of an Abbreviated NDA, or ANDA, for a generic drug, or a Section 505(b)
(2) NDA for another version of such drug during the 5-year exclusive period. However, the submission of an ANDA or Section 505(b)(2) NDA 
containing a paragraph IV certification claiming that a patent listed in the FDA’s Approved Drug Products with Therapeutic Equivalence 
Evaluations, or Orange Book for the drug is invalid or will not be infringed by the manufacture, use or sale of the new product is permitted 
after four years. The submission of a paragraph IV certification may trigger a 30-month stay of approval of the ANDA or Section 505(b)(2) 
NDA. Protection under  

18  

   
Table of Contents  

Hatch-Waxman will not prevent the submission or approval of another full NDA; however, the applicant would be required to conduct its own 
preclinical and adequate and well-controlled clinical studies to demonstrate safety and effectiveness. The Hatch-Waxman Act also provides 3 
years of marketing exclusivity for the approval of new and supplemental NDAs, for, among other things, new indications, dosage forms, or 
strengths of an existing drug, if new clinical investigations that were conducted or sponsored by the applicant are essential to the approval of 
the application.  

IPLEX is currently protected by 3-year exclusivity, which expires on December 12, 2008. This exclusivity runs concurrently with a 7-

year period of orphan drug exclusivity, which prevents the FDA from approving another marketing application for the same drug for the same 
indication, except in the limited circumstances described below. In addition, the FDA’s Orange Book publication lists two patents covering 
IPLEX to which a generic applicant must certify.  

Orphan Drug Designation and Exclusivity  

Some jurisdictions, including Europe and the United States, may designate drugs for relatively small patient populations as Orphan 

Drugs. The FDA grants Orphan Drug Designation to drugs intended to treat a rare disease or condition that affects fewer than 200,000 
individuals in the United States, or in cases where more than 200,000 individuals are affected in the United States, for which there is no 
reasonable expectation that the cost of developing and making available in the United States will be recovered from sales in the United States. 
In the United States, Orphan Drug Designation must be requested before submitting an application for marketing approval. Orphan Drug 
Designation does not convey any advantage in, or shorten the duration of, the regulatory review and approval process. If a product that has 
Orphan Drug Designation subsequently receives FDA approval for the indication for which it has such designation, the product is entitled to 
Orphan Drug Exclusivity, which means the FDA may not approve any other application to market the same drug for the same indication for a 
period of 7 years, except in limited circumstances. After an orphan drug is approved, the FDA can subsequently approve a competitor’s version 
of the same drug for the same indication if the subsequent applicant shows clinical superiority (superior efficacy, safety, or a major contribution 
to patient care) to the approved product with Orphan Drug Exclusivity. Also, competitors may receive approval of different drugs or biologics 
for the indications for which the Orphan Drug has exclusivity.  

IPLEX was approved on December 12, 2005 as an Orphan Drug, and is currently protected by 7-year Orphan Drug Exclusivity for the 
treatment of Severe Primary IGFD. This exclusivity expires on December 12, 2012. This period of exclusivity runs concurrently with the 3-
year period of exclusivity applicable to IPLEX. We have received Orphan Drug Designation for IPLEX for the treatment of extreme insulin 
resistance. We also intend to file for Orphan Drug Designation for other indications that meet the criteria for Orphan Drug Designation. If the 
FDA designates the drug and approves our marketing application, or approves marketing applications under current designations, we will be 
granted seven years of Orphan Drug Exclusivity for the drug for the designated indication. Obtaining FDA approval to market a product with 
Orphan Drug Exclusivity may not provide us with a material commercial advantage.  

Under European Union medicines laws, the criteria for designation as an “orphan medicine” are similar to those in the United States. A 

drug is designated as an Orphan Drug if the sponsor can establish that the drug is intended for a life-threatening or chronically debilitating 
condition affecting no more than five in 10,000 persons in the European Union or that is unlikely to be profitable, and if there is no approved 
satisfactory treatment or if the drug would be a significant benefit to those persons with the condition. Orphan medicines are entitled to ten 
years of market exclusivity, except under certain limited circumstances comparable to U.S. law. During this period of market exclusivity, no 
“similar” product, whether or not supported by full safety and efficacy data, will be approved unless a second applicant can establish that its 
product is safer, more effective or otherwise clinically superior. This period may be reduced to six years if the conditions that originally 
justified Orphan Drug Designation change or the sponsor makes excessive profits. We have been granted Orphan Drug Designation by the 
EMEA for IPLEX in the treatment of growth disturbance due to growth hormone insensitivity syndrome (Laron Syndrome). We have also 
obtained Orphan Drug Designation in the European Union for IPLEX for the treatment of extreme insulin resistance.

Other Regulatory Requirements  

We are also subject to a number of post-approval regulatory requirements. If we seek to make certain changes to an approved product, 

such as promoting or labeling a product for a new indication, making certain manufacturing changes or product enhancements or adding 
labeling claims, we will need FDA review and approval before the change can be implemented. While physicians may use products for 
indications that have not been approved by the FDA, we may not label or promote the product for an indication that has not been approved. 
Securing FDA approval for new indications or product enhancements and, in some cases, for manufacturing and labeling claims, is generally a 
time-consuming and expensive process that may require us to conduct clinical studies under the FDA’s IND regulations. Even if such studies 
are conducted, the FDA may not approve any change in a timely fashion, or at all. In addition, adverse experiences associated with use of the 
products must be reported to the FDA, and FDA rules govern how we can label, advertise or otherwise commercialize our products.  

There are current post-marketing safety surveillance requirements that we need to meet to continue to market an approved product. The 

FDA also may, in its discretion, require post-marketing testing and surveillance to monitor the effects of approved products or place conditions 
on any approvals that could restrict the commercial applications of these products.  

In addition to FDA restrictions on marketing of pharmaceutical products, several other types of state and federal laws have been applied 
to restrict certain marketing practices in the pharmaceutical industry in recent years. These laws include anti-kickback statutes and false claims 
statutes. The federal health care program anti-kickback statute prohibits, among other things, knowingly and willfully offering, paying, 
soliciting or receiving remuneration to induce or in return for purchasing, leasing, ordering or arranging for the purchase, lease or order of any 
health care item or service reimbursable under Medicare, Medicaid or other federally financed health care programs. This statute has been 
interpreted to apply to arrangements between pharmaceutical manufacturers on the one hand and prescribers, purchasers and formulary 
managers on the other. Violations of the anti-kickback statute are punishable by imprisonment, criminal fines, civil monetary penalties and 
exclusion from participation in federal health care programs. Although there are a number of statutory exemptions and regulatory safe harbors 
protecting certain common activities from prosecution or other regulatory sanctions, the exemptions and safe harbors are drawn narrowly, and 
practices that involve remuneration intended to induce prescribing, purchases or recommendations may be subject to scrutiny if they do not 
qualify for an exemption or safe harbor.  

Federal false claims laws prohibit any person from knowingly presenting, or causing to be presented, a false claim for payment to the 
federal government, or knowingly making, or causing to be made, a false statement to have a false claim paid. Recently, several pharmaceutical 
and other health care companies have been prosecuted under these laws for allegedly inflating drug prices they report to pricing services, which 
in turn are used by the government to set Medicare and Medicaid reimbursement rates, and for allegedly providing free product to customers 
with the expectation that the customers would bill federal programs for the product. In addition, certain marketing practices, including off-label 
promotion, may also violate false claims laws. The majority of states also have statutes or regulations similar to the federal anti-kickback law 
and false claims laws, which apply to items and services reimbursed under Medicaid and other state programs, or, in several states, apply 
regardless of the payor.  

In addition, we and our manufacturers are subject to requirements that drugs be manufactured, packaged and labeled in conformity with 
current good manufacturing practice, or cGMP. To comply with cGMP requirements, manufacturers must continue to spend time, money and 
effort to meet requirements relating to personnel, facilities, equipment, production and process, labeling and packaging, quality control, record-
keeping and other requirements. The FDA periodically inspects drug manufacturing facilities to evaluate compliance with cGMP requirements. 

Also, as part of the sales and marketing process, pharmaceutical companies frequently provide samples of approved drugs to physicians. 
This practice is regulated by the FDA and other governmental authorities, including, in particular, requirements concerning record-keeping and 
control procedures.  

20  

   
Table of Contents  

Outside the United States, our ability to market our products will also depend on receiving marketing authorizations from the appropriate 

regulatory authorities. The requirements governing the conduct of clinical studies and marketing authorization vary widely from country to 
country. The foreign regulatory approval process includes risks similar to those associated with FDA approval as described above.  

Employees  

At December 31, 2005, we had 85 employees, including 17 in research and development, 23 in regulatory, clinical and quality assurance, 
28 in manufacturing and 17 in finance and administration. In connection with the commercial launch of IPLEX and to create a sufficient sales 
and marketing capability for the commercialization of other drug and other indications, once approved, we expect to hire approximately 40 
additional employees in our Sales and Marketing department by December 31, 2006. We also expect to hire approximately 40 additional 
employees for manufacturing operations in Boulder, Colorado.  

Our continued success will depend in large measure on our ability to attract and retain highly skilled employees who are in great demand. 

None of our employees are represented by a labor union, and we believe that our relations with the employees are generally good.  

Facilities  

Our Headquarters is located in Glen Allen, Virginia where we occupy approximately 46,000 square feet of space for corporate and 

development activities under a lease expiring in October 2006.  

Our manufacturing facility is located in Boulder, Colorado where we occupy approximately 25,000 square feet dedicated to cGMP 

production of commercial and clinical drug and quality control and 26,000 square feet of space in two adjacent facilities for additional 
laboratory and research and development operations, administrative functions, and cGMP warehouse and dispensing operations. Our lease for 
the Boulder facility dedicated to cGMP manufacturing expires in February 2008 but may be renewed annually for up to an additional 5 years.

Risk Factors Relating to Our Business  

You should consider carefully the following risk factors, together with all of the other information included in this prospectus supplement 

or incorporated by reference into this prospectus supplement. Each of these risk factors could adversely affect our business, operating results 
and financial condition, as well as adversely affect the value of an investment in our common stock.  

Since we have a limited operating history, a history of operating losses and an expectation that we will generate operating losses for the 
foreseeable future, we may not achieve profitability for some time, if at all.  

Until recently, we have been focused solely on drug development and currently have no commercial sales. We have incurred losses each 

year of operation and we expect to continue incurring operating losses for the foreseeable future. The process of developing our products 
requires significant preclinical testing and clinical studies as well as regulatory approvals for commercialization and marketing before we can 
begin to generate any revenue from product sales. In addition, commercialization of our drug candidates will require us to establish a sales and 
marketing organization and contractual relationships to enable product manufacturing, distribution and other related activities. We expect that 
these activities, together with our general and administrative expenses, will result in substantial operating losses for the foreseeable future. As 
of December 31, 2005, our accumulated deficit was $254.7 million. For the year ended December 31, 2005 our consolidated net loss was $40.9 
million.  

We have only one drug that has been approved for commercial sale by the FDA, IPLEX™, and we are in the earlier stages of researching 

and developing two other drug candidates, INSM-18 and rhIGFBP-3. Until we have had an opportunity to establish IPLEX as a commercially 
viable product or complete the development and commercialization of our other drug candidates, we cannot predict our future revenue with any 
degree of certainty.  

For these and other reasons, our independent registered public accounting firm believes that there is substantial doubt that we will be able 

to continue as a going concern. If we do not continue as a going concern our investors will likely lose all of their investments.  

Third-party claims that our products infringe on their proprietary rights may materially adversely affect our business, financial 
condition and results of operations.  

Third parties have claimed that we are infringing or have misappropriated their proprietary rights and we can give no assurances that 
other third parties will not claim that we and our licensees who develop and distribute our products, are infringing their proprietary rights. It is 
difficult to predict with any certainty the outcome of any legal proceeding. If third parties successfully bring legal action against us or our 
licensees claiming patent or other intellectual property infringement, in addition to any potential liability for damages, including compensatory 
damages and treble damages, a court could require us and/or our licensees to cease using any infringing processes or manufacturing and selling 
any infringing products. Such a result would likely have a material adverse effect on our business, financial condition and results of operations. 
Any such claim, with or without merit, could result in costly litigation, require us to pay significant settlement amounts or require us and/or our 
licensees to enter into royalty or licensing agreements, all of which could delay or otherwise adversely impact the development of our potential 
products for commercial use. If a court determines that we may not manufacture or sell our products or use our processes without having 
obtained licenses, there can be no assurance that we and/or our licensees will be able to obtain them on commercially favorable terms, if at all. 
Without such licenses, we and/or our licensees may be unable to develop certain products. Our breach of an existing license or our failure to 
obtain, or our delay in obtaining, a license to any technology that we require to commercialize our products may materially adversely impact 
our business, financial condition and results of operations.  

With respect to any infringement claim asserted by a third party, we can give no assurances that we will be successful in the litigation or 

that such litigation would not have a material adverse effect on our business,  

22  

   
Table of Contents  

financial condition and results of operation. In the event of a successful claim against us for infringement or misappropriation of a third party’s 
proprietary rights, we may be required to:  

• 

• 

• 

   pay damages, including up to treble damages, and the other party’s attorneys’ fees, which may be substantial; 

   cease the development, manufacture, marketing and sale of products or use of processes that infringe the proprietary rights of others; 

   expend significant resources to redesign our products or our processes so that they do not infringe the proprietary rights of others, 

which may not be possible; 

• 

   redesign our products or processes to avoid third party proprietary rights, we may suffer significant regulatory delays associated with 

conducting additional clinical trials or other steps to obtain regulatory approval; and 

• 

   obtain one or more licenses arising out of a settlement of litigation or otherwise from third parties for the infringed proprietary rights, 

which may not be available to us on acceptable terms or at all. 

In this regard, we note that on December 20, 2004, Tercica, Inc. and Genentech, Inc. filed a complaint against Avecia Limited and us in 

the United Kingdom at the High Court of Justice, Chancery Division, Patents Court alleging infringement of EP patent No. 571,417, or the 
‘417 patent. The ‘417 patent has claims directed to particular uses of a combination of IGFBP-3 and IGF-1. In the complaint, Tercica asked the 
court for an injunction to restrain allegedly infringing activity, for a declaration that the ‘417 patent is valid and infringed, for an order 
requiring the delivery or destruction of allegedly infringing articles and materials and for an inquiry into possible economic damages. In May 
2005, we filed for summary judgment to dismiss the complaint. The motion for summary judgment was denied. A trial date in this litigation 
has not been set.  

In addition, on December 23, 2004, Genentech and Tercica sued us for infringement of U.S. Patent Nos. 5,187,151 and 6,331,414 in the 
United States District Court for the Northern District of California. These patents are directed to certain methods of using rhIGF-1/rhIGFBP-3 
and methods of producing rhIGF-1, respectively. On February 16, 2005, Tercica filed an amended complaint, adding an infringement allegation 
against us with respect to U.S. Patent No. 5,528,287, or the ‘287 patent. The claims of the ‘287 patent are directed to DNA encoding BP53 (i.e. 
IGFBP-3) and recombinant constructs, transformed host cells and methods for using the same. Genentech and Tercica claim that the production 
or use of IPLEX, a complex of rhIGF-1/rhIGFBP-3, will infringe these patents. We moved to dismiss the amended complaint for lack of 
jurisdiction and on other grounds. At a hearing on the motion on April 15, 2005, the court granted our motion and dismissed the case with leave 
for plaintiffs to refile the complaint. A second amended complaint was filed on April 22, 2005 by Genentech and Tercica against us that, 
among other things added Celtrix Pharmaceuticals, our wholly-owned subsidiary, as a defendant. We moved to dismiss the portion of the 
second amended complaint that relates to the ‘287 patent. On June 29, 2005, the Court denied our motion to dismiss. On July 14, 2005, we filed 
our answer and counterclaims, in which we denied infringement and sought a declaratory judgment that the asserted patents are not infringed, 
are invalid, and/or are unenforceable. The reply to the counterclaims by Genentech and Tercica was filed on August 5, 2005. On October 17, 
2005, Tercica and Genentech filed a third amended complaint adding Insmed Therapeutic Proteins, our wholly-owned subsidiary, as a 
defendant. The answer and counterclaims in response to the third amended complaint were filed by us on October 27, 2005. Briefing on patent 
claim construction issues and summary judgment motions is set to be completed by May 5, 2006, with a claim construction hearing scheduled 
for May 19, 2006. Discovery is ongoing and a trial date is scheduled for November 2006.  

On May 27, 2005, Genentech and Tercica filed a motion for preliminary injunction seeking an order barring us, until trial, from making, 

using or selling the drug called “SomatoKine,” (now known as IPLEX) with respect to its allegations of infringement of U.S. Patent Nos. 
6,331,414 and 5,187,151, and requesting that we be required to share any Orphan Drug Exclusivity it obtains with Tercica. We filed an 
opposition to the motion for a Preliminary Injunction on June 10, 2005. On June 16, 2005, Genentech and Tercica withdrew their motion for a 
preliminary injunction, but reserved the right to refile the motion for a preliminary injunction. We cannot predict whether Genentech and 
Tercica will seek a preliminary injunction at another time.

We cannot predict with certainty the outcome of proceedings involving Tercica and Genentech. The claim construction ruling and 
summary judgment rulings to be issued by the court, which could occur in the next few months, could have an adverse impact on our position 
in this proceeding, including by narrowing or limiting our defenses. An adverse ruling after trial on any of the claims alleged would have a 
material adverse effect on our business, financial condition and results of operations and would lead to some or all of the consequences 
described above, such as damages and the requirement that we cease manufacture and sale of IPLEX unless we can obtain a license or develop 
or acquire alternative products or processes that do not infringe the patents, which may not be available on commercially favorable terms, if at 
all. Further, we may have an obligation to indemnify distributors if IPLEX and other third parties. In addition, if such adverse ruling requires us 
to cease the manufacture and sale of IPLEX and we are unable to raise the capital that would be necessary to conduct the clinical trials 
necessary to obtain regulatory approval of our other product candidates, we could be forced to curtail our development programs and possibly 
to cease operations altogether.  

These proceedings have required a substantial diversion of financial and personnel resources from operations. Further, defending any 

future patent infringement claims will also require that we divert financial and personnel resources from operations and may expose us to 
liabilities for costs or other damage awards.  

We face uncertainties related to patents and proprietary technology that may materially adversely affect our business, financial 
condition and results of operations.  

Our success will depend in part on our ability to:  

• 

• 

• 

   obtain patent protection for our products; 

   prevent third parties from infringing our patents; and 

   refrain from infringing the patents of others, both domestically and internationally. 

Our patent positions are highly uncertain and involve complex legal and factual questions, and any future patents we receive for our 
potential products will be subject to this uncertainty, which may adversely affect our business, financial condition and results of operations. We 
intend to actively pursue patent protection for products resulting from our research and development activities that have significant potential 
commercial value. Nevertheless, due to the inherent uncertainty of the patent process, it is possible that, in the patent application process, 
certain claims may be rejected or achieve such limited allowance that the value of the patents would be diminished. Further, there can be no 
assurance that any patents obtained will afford us adequate protection. In addition, any patents we procure may require cooperation with 
companies holding related patents. We may have difficulty forming a successful relationship with these other companies.  

Third parties have claimed that we are infringing or have misappropriated their proprietary rights. We can give no assurance that other 
third parties will not make similar claims. Various third parties have obtained, and are attempting to obtain, patent protection relating to the 
production and use of our approved product and product candidates. We can give no assurances as to whether any issued patents, or patents that 
may later issue to third parties, would affect our contemplated commercialization of IPLEX or any other product. We can give no assurances 
that such patents can be avoided, invalidated or licensed.  

Furthermore, litigation with any third party, even if the allegations are without merit, would likely be expensive and time-consuming and 

divert management’s attention.  

Any conclusions we may have reached regarding non-infringement and invalidity are based in part on a review of publicly available 
databases and other information. There may be information not available to or otherwise not reviewed by us that might change our conclusions. 
Moreover, as described above, the scope and validity of patent claims are determined based on many facts and circumstances, and in a 
litigation a court may reach a different conclusion on any given patent claim than the conclusions that we have reached.  

24  

   
   
   
   
  
  
  
Table of Contents  

We note that third parties with significant financial resources, including Genentech, Inc., Novartis and Chiron Corporation hold United 
States and/or foreign patents possibly directed to the composition, production and/or use of rhIGF-1, rhIGFBP-3, IPLEX and/or recombinant 
proteins. We can provide no assurance that any one of these third parties will not assert an infringement action against us that may adversely 
affect our ability to make, use or sell our products.  

We may have to undertake costly litigation to enforce any patents issued or licensed to us or to determine the scope and validity of 
another party’s proprietary rights. We can give no assurances that a court of competent jurisdiction would validate our issued or licensed 
patents. An adverse outcome in litigation or an interference or other proceeding in a court or patent office could result in the invalidation of our 
patents and could otherwise materially adversely affect our business, financial condition and results of operations.  

All of our products are currently in, or have just completed, the research and development stage. If we are unable to commercialize 
them it will materially adversely affect our business, financial condition and results of operations.  

Even if we are successful in developing and obtaining approval for our drug candidates, there are numerous circumstances that could 

prevent the successful commercialization of the products such as:  

• 

   the regulatory approvals of our products are delayed or we are required to conduct further research and development of our products 

prior to receiving regulatory approval; 

• 

• 

• 

• 

   we are unable to build a sales and marketing group to successfully launch and sell our products; 

   we are unable to raise the additional funds needed to successfully develop and commercialize our products or acquire additional 

products for growth; 

   we are required to allocate available funds to litigation matters; 

   we are unable to manufacture the quantity of product needed in accordance with current good manufacturing practices to meet market 

demand, or at all; 

• 

   our product is determined to be ineffective or unsafe following approval and is removed from the market or we are required to 

perform additional research and development to further prove the safety and effectiveness of the product before re-entry into the 
market; 

• 

• 

• 

• 

   competition from other products or technologies prevents or reduces market acceptance of our products; 

   we do not have and cannot obtain the intellectual property rights needed to manufacture or market our products without infringing on 

another company’s patents; 

   we are unsuccessful in defending against patent infringement claims being brought against us our products or technologies; or 

   we are unable to obtain reimbursement for our product or such reimbursement may be less than is necessary to produce a reasonable 

profit. 

Our growth strategy includes the commercialization of more than one product. We may not be able to identify and acquire 

complementary products, businesses or technologies and if acquired or licensed, they might not improve our business, financial condition or 
results of operations.  

We currently have limited sales, marketing and distribution capabilities, which may make commercializing our products difficult. If 
we are unable to build sales, marketing and distribution capabilities, it will materially adversely affect our business, financial condition 
and results of operations.  

Now that the FDA has permitted us to commence commercial sales of IPLEX, we must establish capabilities to complete the commercial 

sale, marketing and distribution of IPLEX. These are areas in which we  

25

have no experience. To market IPLEX or any of our products directly, we must develop a marketing and sales force with technical expertise 
and with supporting distribution capability. We may engage a pharmaceutical company with a large distribution system and a large direct sales 
force to assist us in marketing IPLEX outside the United States or in marketing any of our other products. There can be no assurance that we 
will successfully establish sales and distribution capabilities or establish third-party sales and distribution arrangements on satisfactory terms, 
or at all. To the extent we enter into co-promotion, licensing, third-party sales or distribution agreements, any revenues we receive will depend 
on the efforts of third parties and there can be no assurance that our efforts will succeed. Failure to successfully sell, market or distribute our 
products once approved will materially adversely affect our business, financial condition and results of operations.  

If our products fail to achieve market acceptance for any reason, such failure may materially adversely affect our business, financial 
condition and results of operations.  

There can be no assurance that any of our approved drug and our drug candidates, if approved for marketing, will achieve market 

acceptance. If our drugs and drug candidates, once approved, do not receive market acceptance for any reason, it will adversely affect our 
business, financial condition and results of operations. The degree of market acceptance of any drugs we develop will depend on a number of 
factors, including:  

• 

• 

• 

• 

   the establishment and demonstration in the medical community of the clinical efficacy and safety of our drugs; 

   their potential advantage over existing and future treatment methods; 

   their price; and 

   reimbursement policies of government and third-party payers, including hospitals and insurance companies. 

For example, even after we obtain regulatory approval to sell our products, physicians and healthcare payers could conclude that our 

products are not safe and effective and physicians could choose not to use them to treat patients. Our competitors may also develop new 
technologies or products which are more effective or less costly, or that seem more cost-effective than our products.  

In addition, legislation and regulations affecting the pricing of pharmaceuticals may change in ways adverse to us. While we cannot 

predict the likelihood of any such legislative or regulatory proposals, if the government or an agency adopts such proposals, they could 
materially adversely affect our business, financial condition and results of operations.  

If there are fewer children with Severe Primary IGFD than we estimate, we may not generate sufficient revenues to continue 
development of other products or to continue operations, or we may not be able to complete our clinical studies.  

We estimate that the number of children in the United States with Severe Primary IGFD is approximately 6,000. Our estimate of the size 
of the patient population is based on our interpretation of published studies. If our interpretation and extrapolation of data from these published 
studies do not accurately reflect the number of children with Severe Primary IGFD, our assessment of the market may be incorrect and we may 
not achieve sufficient revenue to continue operations.  

Reimbursement policies and changes in the health care system may adversely affect the sale of our current and future products or our 
ability to obtain an adequate level of reimbursement or acceptable prices for our current and future products.  

Our ability to earn sufficient returns on IPLEX or our other products, if and when such products are approved and ready for marketing, 

will depend in part on the extent to which reimbursement for our products and  

26  

   
   
   
   
   
  
  
  
  
Table of Contents  

related treatments will be available from government health administration authorities, private health coverage insurers, managed care 
organizations and other third-party payers. If we fail to obtain appropriate reimbursement, it could prevent us from successfully 
commercializing our future products.  

There have been and continue to be efforts by governmental and third-party payers to contain or reduce the costs of health care through 

various means, including limiting coverage and the level of reimbursement. We expect that there will continue to be a number of legislative 
proposals to implement government controls and other reforms to limit coverage and reimbursement. The announcement of these proposals or 
reforms could impair our ability to raise capital. The adoption of these proposals or reforms could impair our operations and financial 
condition.  

Additionally, third-party payers, including Medicare, are increasingly challenging the price of medical products and services and are 

limiting the reimbursement levels offered to consumers for these medical products and services. If purchasers or users of our future products 
are not able to obtain adequate reimbursement from third-party payers for the cost of using these products, they may forego or reduce their use. 
Significant uncertainty exists as to the reimbursement status of newly approved health care products and whether adequate third-party coverage 
will be available.  

We cannot provide any assurance that third-party payers will provide adequate reimbursement, if any, for IPLEX.  

We cannot be certain that we will obtain additional regulatory approvals in the United States and Europe. The failure to obtain such 
approvals may materially adversely affect our business, financial condition and results of operations.  

We are required to obtain various regulatory approvals prior to studying our drug products in humans and then again before we market 

and distribute our products. The regulatory review and approval process required to perform a clinical study in both the United States and 
Europe includes evaluation of preclinical studies and clinical studies, as well as the evaluation of our manufacturing process and is complex, 
lengthy, expensive, resource intensive and uncertain. Securing regulatory approval to market our products also requires the submission of 
extensive preclinical and clinical data, manufacturing information regarding the process and facility, scientific data characterizing our product 
and other supporting data to the regulatory authorities in order to establish its safety and effectiveness. This process is also complex, lengthy, 
expensive, resource intensive and uncertain. We have limited experience in filing and pursuing applications necessary to gain these regulatory 
approvals.  

Data submitted to the regulators is subject to varying interpretations that could delay, limit or prevent regulatory agency approval. We 
may also encounter delays or rejections based on changes in regulatory agency policies during the period in which we develop a drug and/or 
the period required for review of any application for regulatory agency approval of a particular product. Delays in obtaining regulatory agency 
approvals could adversely affect the marketing of any drugs that our collaborative partners or we develop. Such delays could impose costly 
procedures on our collaborative partners’ or our activities, diminish any competitive advantages that our collaborative partners or we may attain 
and adversely affect our ability to receive royalties, any of which could materially adversely affect our business, financial condition and results 
of operations.  

We are currently conducting a Phase III clinical trial of IPLEX in patients with Severe Primary IGFD and plan to include the data in a 
MAA submission to the EMEA. We must receive approval of these applications before we can market IPLEX in certain countries outside of 
the United States.  

As part of our normal development we continue to increase our scale of production and refine our manufacturing process. Because of 

these changes we are required to perform various comparability analyses to demonstrate that the drug product used in our previous 
development studies and for commercialization is essentially the same as the new drug product produced. We have had several discussions 
with the FDA and intend to have discussions with foreign regulatory agencies regarding our Phase III clinical study and this comparability 
analysis. We believe we understand what is required to satisfy the EMEA. We plan to submit this  

27  

   
   
Table of Contents  

data to the appropriate regulatory authorities as part of the regulatory process. If we do not properly understand what is required to satisfy 
regulatory authorities or if we are unable to produce comparable drug product or meet the regulatory requirements of comparability it will 
materially adversely affect our business, financial condition and results of operations.  

Regulatory authorities have substantial discretion in the approval of our drug candidates and may either refuse to accept our applications, 
or may decide after review of our applications that our data is insufficient to allow approval of IPLEX. If the EMEA does not accept or approve 
our application, it may require that we conduct additional clinical, preclinical or manufacturing studies and submit that data before it will 
reconsider our application. This could materially adversely affect our business, financial condition and results of operations.  

Even if the FDA or the EMEA grants approval for a drug, such approval may limit the indicated uses for which we may market the drug, 

and this could limit the potential market for such drug. Furthermore, if we obtain approval for any of our products, the marketing and 
manufacture of such products remain subject to extensive regulatory requirements. Further, any such approval would be subject to continual 
review, and later discovery of unknown problems could restrict the products’ future use or cause their withdrawal from the market. Failure to 
comply with regulatory requirements could, among other things, result in fines, suspension of regulatory approvals, operating restrictions and 
criminal prosecution. In addition, many countries require regulatory agency approval of pricing and may also require approval for the 
marketing in such countries of any drug that our collaborative partners or we develop.  

If the results of our Phase III clinical trial for IPLEX do not continue to support the approval of IPLEX or if we cannot produce 
comparable drug product, have not correctly understood the regulatory requirements associated with comparability of drug products or for 
various other reasons cannot satisfy ongoing regulatory requirements, we may not receive FDA and/or EMEA approvals or such approvals may 
be substantially delayed or withdrawn. Any of these events might prevent us from selling IPLEX in its approved indication or from expanding 
the market for IPLEX, either of which would materially adversely affect our business, financial condition and results of operations.  

Even if we obtain approval for our products in the United States or the European Union, we cannot be certain that we will obtain any 
regulatory approvals in other countries. The failure to obtain such approvals may materially adversely affect our business, financial 
condition and results of operations.  

In order to market our products outside of the United States and European Union territories, our corporate partners and we must comply 

with numerous and varying regulatory requirements of other countries. The approval procedures vary among countries and can involve 
additional product testing and administrative review periods. The time required to obtain approval in these other territories might differ from 
that required to obtain FDA or EMEA approval. The regulatory approval process in these other territories includes at least all of the risks 
associated with obtaining FDA and EMEA approval detailed above. Approval by the FDA or the EMEA does not ensure approval by the 
regulatory authorities of other countries. The failure to obtain such approvals may materially adversely affect our business, financial condition 
and results of operations.  

We are currently a defendant in a civil action in which we are accused of deceptive promotional statements and unfair business 
practices. An unfavorable settlement or judgment in this action could harm our business and financial condition.  

On December 6, 2005, Tercica filed a complaint against us in the United States District Court for the Northern District of California 
alleging we made deceptive promotional statements and engaged in unfair business practices related to Tercica’s drug, Increlex, in violation of 
the California Business and Professions Code and the Federal Lanham Act. Tercica amended the complaint on December 15, 2005. Tercica is 
requesting injunctive and monetary relief.

Although we deny any liability, no assurances can be given as to the outcome of this action. An unfavorable settlement or decision could 
affect our ability to make, use or sell our products, and would have a material adverse effect on our business, financial condition and results of 
operations. Any liability resulting from this action may exceed our financial resources. The parties have not initiated discovery in this action 
and no trial date has been set.  

An inability to compete successfully will materially adversely affect our business, financial condition and results of operations.  

We engage in a business characterized by extensive research efforts, rapid developments and intense competition. We cannot assure that 
our products will compete successfully or that research and development by others will not render our products obsolete or uneconomical. Our 
failure to compete effectively would materially adversely affect our business, financial condition and results of operations. We expect that 
successful competition will depend, among other things, on product efficacy, safety, reliability, availability, timing and scope of regulatory 
approval and price. Specifically, we expect crucial factors will include the relative speed with which we can develop products, complete the 
clinical testing and regulatory approval processes and supply commercial quantities of the product to the market. We expect competition to 
increase as technological advances are made and commercial applications broaden. In each of our potential product areas, we face substantial 
competition from large pharmaceutical, biotechnology and other companies, as well as universities and research institutions. Relative to us, 
most of these entities have substantially greater capital resources, research and development staffs, facilities and experience in conducting 
clinical studies and obtaining regulatory approvals, as well as in manufacturing and marketing pharmaceutical products. Many of our 
competitors may achieve product commercialization or patent protection earlier than we will. Furthermore, we believe that our competitors 
have used, and may continue to use, litigation to gain a competitive advantage. Finally, our competitors may use different technologies or 
approaches to the development of products similar to the products we are seeking to develop.  

Currently, we are aware of at least one other company, Tercica, that has received approval from the FDA for a rhIGF-1 product for an 
indication very similar to the indication for which IPLEX has been approved. Tercica’s product was approved for the long term treatment of 
growth failure in children with severe primary IGF-1 deficiency or with growth hormone gene deletion who have developed neutralizing 
antibodies to growth hormone. We believe this indication would include patients with Severe Primary IGFD. Because there are already patients 
using Tercica’s product, the market opportunity for IPLEX may be diminished if doctors who are already prescribing Tercica’s product to their 
patients are unwilling to switch their patients to a different drug. We believe Tercica may also be planning to develop rhIGF-1 for some of the 
same indications that we plan to pursue with IPLEX.  

Growth hormone may also be a competitive product for the treatment of some indications that we may pursue with IPLEX such as HIV 

associated adipose redistribution syndrome. The major suppliers of commercially available growth hormone are Genentech, Eli Lilly, Novo 
Nordisk, Pfizer and Serono. We believe that Novo Nordisk may be conducting clinical studies for the use of its growth hormone in pediatric 
IGF-1 deficiency. We are also aware that Serono is seeking regulatory approval for their growth hormone, Serostim™, for the treatment of HIV 
associated adipose redistribution syndrome, and that Theratechnologies is conducting Phase III studies for a growth hormone releasing agonist 
for the treatment of HIV associated adipose redistribution syndrome.  

In addition, we believe that Genentech, Merck, Novo Nordisk and Pfizer have previously conducted research and development of orally-

available small molecules that cause the release of growth hormone, known as growth hormone secretagogues. We are not aware of any 
continued clinical development of these molecules by these companies. We believe that Rejuvenon Corporation may have licensed certain 
rights to Novo Nordisk’s growth hormone secretagogues, which are in preclinical development. We are also aware that Theratechnologies is 
developing various peptides that stimulate the release of hormones that could be used in the treatment of some of the same indications we plan 
to pursue with IPLEX.

Many companies are pursuing the development of products for the treatment of cancer. Our competitors include multinational 

pharmaceutical companies, specialized biotechnology firms, and universities and other research institutions. Although we are unaware of any 
companies developing rhIGFBP-3 for cancer, we are aware of companies that are developing products that are intended to target the same IGF-
1 pathway as rhIGFBP-3. These companies include ImClone, Amgen, OSI Pharmaceuticals, Bristol-Myers Squibb and Genentech.  

Biotechnology and related pharmaceutical technology have undergone and should continue to experience rapid and significant change. 

We expect that the technologies associated with biotechnology research and development will continue to develop rapidly. Our future success 
will depend in large part on our ability to maintain a competitive position with respect to these technologies. Any compounds, products or 
processes that we develop may become obsolete before we recover any expenses incurred in connection with their development. Rapid 
technological change could make our products obsolete, which could materially adversely affect our business, financial condition and results of 
operations.  

Our inability to compete in our industry could materially adversely affect our business, financial condition and results of operations.  

Competitors could develop and gain FDA approval of products containing rhIGF-1, which could adversely affect our competitive 
position in all indications where we are currently developing IPLEX.  

rhIGF-1 manufactured by other parties may be approved for use in other indications in the United States in the future, including myotonic 

muscular dystrophy, HIV associated adipose redistribution syndrome and severe insulin resistance. In the event there are other rhIGF-1 
products approved by the FDA to treat indications other than those covered by IPLEX, physicians may elect to prescribe a competitor’s product 
containing rhIGF-1 to treat the indications for which IPLEX has received and may receive approval. This is commonly referred to as off-label 
use. While under FDA regulations a competitor is not allowed to promote off-label use of its product, the FDA does not regulate the practice of 
medicine and as a result cannot direct physicians as to what product containing rhIGF-1 to prescribe to their patients. As a result, we would 
have limited ability to prevent off-label use of a competitor’s product containing rhIGF-1 to treat any diseases for which we have received FDA 
approval even if it violates our patents and/or we have orphan drug exclusivity for the use of rhIGF-1 to treat such diseases.  

If another party obtains Orphan Drug Exclusivity for a product that is essentially the same as a product we are developing in a 
particular indication, we may be precluded or delayed from commercializing the product in that indication. This may materially 
adversely affect our business, financial condition and results of operations.  

Under the Orphan Drug Act, the FDA may grant Orphan Drug Designation to drugs intended to treat a rare disease or condition, which is 

generally a disease or condition that affects fewer than 200,000 individuals in the United States. The company that obtains the first marketing 
approval from the FDA for a designated orphan drug for a rare disease receives marketing exclusivity for use of that drug for the designated 
condition for a period of seven years. Similar laws exist in Europe. If a competitor obtains approval of the same drug for the same indication or 
disease before us, we would be blocked from obtaining approval for our product for seven or more years, unless our product can be shown to 
be clinically superior. In addition, more than one drug may be approved by the FDA for the same orphan indication or disease as long as the 
drugs are different drugs. As a result, even if our product is approved and receives Orphan Drug Exclusivity, as in the case of our drug IPLEX, 
the FDA can still approve different drugs for use in treating the same indication or disease covered by our product, which could create a more 
competitive market for us. For example, the FDA approved Tercica’s drug, Increlex™, for the treatment of Severe Primary IGFD and granted 
Tercica’s product Orphan Drug Exclusivity. Therefore, Tercica’s product will compete with IPLEX for the treatment of Severe Primary IGFD 
when IPLEX is launched commercially and the value of IPLEX’s Orphan Drug Status in this indication will be limited.

Confidentiality agreements with employees and others may not adequately prevent disclosure of trade secrets and other proprietary 
information. Disclosure of this information may materially adversely affect our business, financial condition and results of operations.  

In order to protect our proprietary technology and processes, we rely in part on confidentiality agreements with our corporate partners, 
employees, consultants, outside scientific collaborators and sponsored researchers and other advisors. These agreements may not effectively 
prevent disclosure of confidential information and may not provide an adequate remedy in the event of unauthorized disclosure of confidential 
information. In addition, others may independently discover trade secrets and proprietary information. Costly and time-consuming litigation 
could be necessary to enforce and determine the scope of our proprietary rights, and failure to obtain or maintain trade secret protection could 
adversely affect our competitive business position.  

We may not be able to manufacture quantities of IPLEX sufficient to meet market demand, or manufacturing capacity necessary to 
supply IPLEX, rhIGFBP-3 or INSM-18 for use in clinical studies may not be available, which may adversely affect our business, 
financial condition and results of operations. If we are unable to find sufficient manufacturing capacity or successfully implement our 
own manufacturing capabilities, it could materially adversely affect our business, financial condition and results of operations.  

Failure to successfully manufacture our products could materially adversely affect our business, financial condition and results of 
operations. We intend to manufacture IPLEX and rhIGFBP-3 bulk drug substance and perform the majority of analytical testing at our 
manufacturing facility in Boulder, Colorado and utilize contract manufacturers for sterile filtering, filling, finishing, labeling and some 
analytical testing. We intend to manufacture INSM-18 with contract manufacturers.  

In order to meet anticipated commercial and clinical demand for IPLEX and clinical demand for rhIGFBP-3, we plan to implement 
stepwise changes to our Boulder, Colorado manufacturing facility and manufacturing process beginning this year. We must submit to the FDA 
information and data pertaining to these changes and the FDA must approve these changes before we will be allowed to use IPLEX or 
rhIGFBP-3 that is manufactured following implementation of these changes.  

There can be no assurance that we will be successful in implementing changes to our manufacturing facility or process for making IPLEX 
and rhIGFBP-3 or that the FDA will review and approve these changes in a timely manner or at all or that contract manufacturers will have the 
capacity to produce and test our products. If we are unable to implement the required changes to our manufacturing facility and process or there 
is a delay in the implementation and approval of these changes, we will be limited to our current manufacturing capacity and would not be able 
to meet the market or clinical demand which would adversely affect the development and commercialization of IPLEX and rhIGFBP-3. If our 
contract manufacturers are unable to meet our sterile filtering, filling, finishing, labeling and analytical testing needs, in a way that meets our 
time and cost parameters, our commercialization of IPLEX and the development and timing of our preclinical and clinical studies may be 
adversely affected.  

In addition, there can be no assurance that an adverse regulatory inspection at our manufacturing facility or contract manufacturer would 

not impede our commercial supply capability. We have chosen to commercialize IPLEX on our own and this is time consuming, resource 
intensive and capital intensive. If our facilities and contract manufacturers cannot produce and test our products according to current good 
manufacturing practices, or cGMP, and pass a cGMP inspection, we may be unable to develop and commercialize our products. This would 
materially adversely affect our business, financial condition and results of operations.  

The available capacity for the manufacture and testing of recombinant proteins that comprise IPLEX is limited. A shutdown or disruption 
at our manufacturing facility due to technical, regulatory or other problems, resulting in an interruption in supply of these materials, could delay 
our development activities and adversely impact our business, financial condition and results of operations.  

31  

   
Table of Contents  

Our manufacturing facility and contract manufacturers must undergo inspections by the FDA and/or the EMEA for compliance with 
cGMP regulations. In the event these facilities do not continue to receive satisfactory cGMP inspections for the manufacture and testing of our 
products, we may need to fund additional modifications to our manufacturing or testing processes, conduct additional validation studies, or find 
alternative manufacturing and testing facilities, any of which would result in significant cost to us as well as a significant delay of up to several 
years in obtaining additional approvals for IPLEX or continuation of the development of our products. In addition, our manufacturing facility 
and any contract manufacturer we may utilize will be subject to ongoing periodic inspection by the FDA, the EMEA and other foreign agencies 
for compliance with cGMP regulations and similar foreign standards. We have limited control over contract manufacturers’ compliance with 
these regulations and standards.  

Product for our clinical studies is currently made at our manufacturing facility and then sent to contract manufacturers for sterile 
filtration, filling into vials and some analytical testing. Should our manufacturing facility or our contract manufacturers become unavailable to 
us for any reason, including damage from any event, including fire, flood, earthquake or terrorism, we may be unable to complete manufacture 
of IPLEX or validation of the manufacturing process for IPLEX. This could delay the sale and marketing of IPLEX, our clinical studies and the 
approval of our MAA, which would delay or otherwise adversely affect revenues. If the damage to any of these facilities is extensive or if our 
contract manufacturer is unwilling or unable to perform under our agreements, we will need to find alternative facilities. The number of 
contract manufacturers with the expertise and facilities to manufacture IPLEX bulk drug substance on a commercial scale in accordance with 
cGMP regulations is extremely limited and it would take a significant amount of time and resources to arrange for alternative manufacturers. If 
we need to change to other contract manufacturers, we would also need to transfer to these new manufacturers and validate the processes and 
analytical methods necessary for the production and testing of IPLEX. Any of these factors could lead to (1) the delay or suspension of our 
clinical studies, regulatory submissions, regulatory approvals or commercialization of IPLEX, or (2) higher costs of production, or (3) our 
failure to effectively commercialize IPLEX or our other drug candidates.  

Furthermore, if our manufacturing facility or our contract manufacturers fail to deliver sufficient quantities of bulk drug substance or 

finished product on a timely basis and at commercially reasonable prices, and we are unable to promptly find one or more replacement 
manufacturers capable of production at a substantially equivalent cost, in substantially equivalent volume and on a timely basis, we will likely 
be unable to meet demand for IPLEX and we would lose potential revenues.  

We need collaborative relationships to be successful. If we are unable to form these relationships it could materially adversely impact 
our business, financial condition and results of operations.  

We currently rely and may in the future rely on a number of significant collaborative relationships for intellectual property rights, 
research funding, manufacturing, analytical services, preclinical development, clinical development and/or sales and marketing. For example, 
almost all of our clinical trial work is done in collaboration with academic institutions and we have licensed intellectual property to permit the 
development, manufacture and commercialization of IPLEX and our drug candidates. Reliance on collaborative relationships poses a number 
of risks, including the following:  

• 

• 

   we may not be able to effectively control whether our corporate partners will devote sufficient resources to our programs or product; 

   disputes may arise in the future with respect to the ownership of rights to technology developed with, licensed to or licensed from 

corporate partners; 

• 

   disagreements with corporate partners could result in loss of intellectual property rights, delay or terminate the research, development 

or commercialization of product candidates or result in litigation or arbitration; 

• 

   contracts with our corporate partners may fail to provide sufficient protection of our intellectual property; 

32  

   
   
   
   
   
  
  
  
  
Table of Contents  

• 

• 

   we may have difficulty enforcing the contracts if one of these partners fails to perform; 

   corporate partners have considerable discretion in electing whether to pursue the development of any additional products and may 

pursue technologies or products either on their own or in collaboration with our competitors; and 

• 

   corporate partners with marketing rights may choose to devote fewer resources to the marketing of our products than they do to 

products of their own development. 

Given these risks, a great deal of uncertainty exists regarding the success of our current and future collaborative efforts. Failure of these 

efforts could delay, impair or prevent the development and commercialization of our products and adversely affect our business, financial 
condition and results of operations.  

Our long-term viability and growth depend on the successful development and commercialization of our products. Pharmaceutical 
product development is an expensive, high risk, lengthy, complicated, resource intensive process.  

Our long-term viability and growth depend on the successful development and commercialization of additional products which lead to 

revenue and profits. All of our products other than IPLEX are in the research and development stage. Our products must be successfully 
developed prior to commercialization. Pharmaceutical product development is an expensive, high risk, lengthy, complicated, resource intensive 
process. In order to succeed, among other things, we must be able to:  

• 

• 

• 

• 

• 

• 

• 

• 

• 

   identify potential drug product candidates; 

   design and conduct appropriate laboratory, preclinical and other research; 

   submit for and receive regulatory approval to perform clinical studies; 

   design and conduct appropriate preclinical and clinical studies according to good laboratory and good clinical practices; 

   select and recruit clinical investigators; 

   select and recruit subjects for our studies; 

   collect, analyze and correctly interpret the data from our studies; 

   submit for and receive regulatory approvals for marketing; and 

   manufacture the drug product candidates according to current good manufacturing practices. 

The development program with respect to any given product will take many years and thus delay our ability to generate profits. In 
addition, potential products that appear promising at early stages of development may fail for a number of reasons, including the possibility that 
the products may require significant additional testing or turn out to be:  

• 

• 

• 

• 

• 

   unsafe; 

   not effective; 

   too difficult or expensive to develop or manufacture; 

   too difficult to administer; or 

   unstable. 

In order to conduct the development programs for our potential products we must, among other things, be able to successfully:  

• 

   raise sufficient money to pay for the development;

• 

• 

   attract and retain appropriate personnel; and 

   develop relationships with other companies to perform various development activities that we are unable to perform. 

If our products fail in preclinical or clinical studies or if we cannot enroll enough patients to complete our clinical studies, such failure 
may adversely affect our business, financial condition and results of operations.  

In order to sell our products, we must receive regulatory approval. Before obtaining regulatory approvals for the commercial sale of any 
of our products under development, we must demonstrate through preclinical studies and clinical studies that the product is safe and effective 
for use in each target indication. In addition, the results from preclinical testing and early clinical studies may not be predictive of results 
obtained in later clinical studies. There can be no assurance that our clinical studies will demonstrate sufficient safety and effectiveness to 
obtain regulatory approvals. A number of companies in the biotechnology and pharmaceutical industries have suffered significant setbacks in 
late stage clinical studies even after promising results in early stage development. If our products fail in preclinical or clinical studies, it may 
have an adverse effect on our business, financial condition and results of operations.  

We are currently conducting a Phase III clinical trial of IPLEX in patients with Severe Primary IGFD and plan to include the data from 

the trial in a Marketing Authorization Application, or MAA, to the European Medicines Agency, or EMEA. We must receive approval of these 
applications before we can market IPLEX in certain countries outside of the United States. We are also planning and conducting clinical studies 
with INSM-18 and rhIGFBP-3.  

The completion rate of these and other clinical studies is dependent on, among other factors, the patient enrollment rate. Patient 

enrollment is a function of many factors, including:  

• 

• 

• 

• 

• 

• 

• 

   Investigator identification and recruitment; 

   regulatory approvals to initiate study sites; 

   patient population size; 

   the nature of the protocol to be used in the trial; 

   patient proximity to clinical sites; 

   eligibility criteria for the study; and 

   competition from other companies’ clinical studies for the same patient population. 

We believe our planned procedures for enrolling patients are appropriate; however, delays in patient enrollment would increase costs and 

delay ultimate commercialization and sales, if any, of our products. Such delays could materially adversely affect our business, financial 
condition and results of operations.  

We may be required to conduct broad, long-term clinical studies to address concerns that the long-term use of IPLEX in broader 
chronic indications might increase the risk of diabetic retinopathy. This may materially adversely affect our business, financial 
condition and results of operations.  

In previously published clinical studies of rhIGF-1, concerns were raised that long-term use of rhIGF-1 might lead to an increased 
incidence and/or severity of retinopathy, a disease of new blood vessel growth in the eye which results in loss of vision. Because our product 
contains rhIGF-1, the FDA may require us to conduct broad, long-term clinical studies to address these concerns prior to receiving FDA 
approval for broad chronic indications such as diabetes. These clinical studies would be expensive and could delay or prevent our 
commercialization of IPLEX for these broader chronic indications. Adverse results from these studies could prevent our commercialization of 
IPLEX for broad chronic indications or could jeopardize existing development and approvals in other indications.

We will need additional funds in the future to continue our operations, but we face uncertainties with respect to our access to capital 
that could materially adversely impact our business, financial condition and results of operations.  

We will require substantial future capital in order to execute our business plan. Our future capital requirements will depend on many 

factors, including factors associated with:  

• 

• 

• 

• 

• 

• 

• 

• 

• 

• 

• 

   obtaining marketing, sales and distribution capabilities; 

   launching products; 

   other activities required for product commercialization; 

   litigation; 

   manufacturing; 

   process development; 

   research and development, including, among other items, preclinical testing and clinical studies; 

   obtaining regulatory approvals; 

   retaining employees and consultants; 

   filing and prosecuting patent applications and enforcing patent claims; and 

   establishing strategic alliances. 

We may also need to spend more money than currently expected because we may change our drug development plans, acquire additional 

drugs or drug candidates or we may misjudge our costs. We have no committed sources of capital and do not know whether additional 
financing will be available when needed, or, if available, that the terms will be favorable. There can be no assurance that our cash reserves 
together with any subsequent funding will satisfy our capital requirements. The failure to satisfy our capital requirements will adversely affect 
our business, financial condition and results of operations. Without additional funding, we do not believe that existing cash reserves, including 
amounts raised in our March 15, 2005 financing, will sufficiently fund our activities through the next twelve months. Our independent 
registered public accounting firm has indicated that there are material uncertainties which cast significant doubt upon our ability to continue as 
a going concern. The addition of this going concern disclosure may discourage investors from purchasing our stock.  

We may seek additional funding through strategic alliances, private or public sales of our securities or licensing all or a portion of our 

technology. Such funding may significantly dilute existing shareholders or may limit our rights to our currently developing technology. There 
can be no assurance, however, that we can obtain additional funding on reasonable terms, or at all. If we cannot obtain adequate funds, we may 
need to significantly curtail our product development programs and/or relinquish rights to our technologies or drug candidates. This may 
adversely affect our business, financial condition and results of operations.  

We are dependent upon retaining and attracting key personnel and others, the loss of which could materially adversely affect our 
business, financial condition and results of operations.  

We depend highly on the principal members of our scientific and management staff, the loss of whose services might significantly delay 

or prevent the achievement of research, development or business objectives and would materially adversely affect our business, financial 
condition and results of operations. Our success depends, in large part, on our ability to attract and retain qualified management, scientific and 
medical personnel, and on our ability to develop and maintain important relationships with commercial partners, leading research institutions 
and key distributors. A number of factors affect our ability to attract qualified personnel, including our size, our location, our status as a public 
company and our uncertain prospects. We face intense competition for such personnel and relationships. We cannot assure that we will attract 
and retain appropriate persons or maintain such relationships.

We expect that our potential expansion into areas and activities requiring additional expertise, such as further clinical studies, 

governmental approvals, manufacturing, sales, marketing and distribution will place additional requirements on our management, operational 
and financial resources. We expect that these demands will require an increase in management and scientific personnel and the development of 
additional expertise by existing management personnel. The failure to attract and retain such personnel or to develop such expertise could 
materially adversely affect our business, financial condition and results of operations.  

Our research, development and manufacturing activities involve the use of hazardous materials, which could expose us to damages 
that could materially adversely affect our business, financial condition and results of operations.  

Our research, development and manufacturing activities involve the controlled use of hazardous materials, including hazardous chemicals 
and radioactive materials. We believe that our procedures for handling hazardous materials comply with federal and state regulations; however, 
there can be no assurance that accidental injury or contamination from these materials will not occur. We currently maintain a general liability 
insurance policy that has a $1.0 million per claim limit and also caps aggregate claims at $2.0 million. In addition, we have an umbrella 
insurance policy that covers up to $2.0 million of liability in excess of the general liability policy’s $2.0 million limit. In the event of an 
accident, we could be held liable for damages, which would likely exceed our insurance coverage and other available financial resources. This 
liability would limit our ability to commercialize IPLEX and develop other products which would materially adversely affect our business, 
financial condition and results of operations.  

We are subject to federal, state and local laws and regulations governing the use, manufacture, storage, handling and disposal of 
hazardous materials and waste products. These laws and regulations may require us to incur significant costs to comply with environmental 
laws and regulations in the future that could materially adversely affect our business, financial condition and results of operations.  

We may be subject to product liability claims if our products harm people, and we have only limited product liability insurance.  

The manufacture and sale of human therapeutic products involve an inherent risk of product liability claims and associated adverse 
publicity. We currently have only limited product liability insurance for clinical studies and no commercial product liability insurance. We do 
not know if we will be able to maintain existing or obtain additional product liability insurance on acceptable terms or with adequate coverage 
against potential liabilities. This type of insurance is expensive and may not be available on acceptable terms. If we are unable to obtain or 
maintain sufficient insurance coverage on reasonable terms or to otherwise protect against potential product liability claims, we may be unable 
to commercialize our products. A successful product liability claim brought against us in excess of our insurance coverage, if any, may require 
us to pay substantial amounts. This could have a material adverse effect on our business, financial condition and results of operations.  

It is illegal for us to promote IPLEX for uses other than those approved by the regulatory authorities. Such off-label promotion, as it is 
known, may result in regulatory actions against us even if such activities by us are inadvertent.  

Physicians may prescribe drugs for uses that are not described in the product’s labeling and that differ from those approved by the FDA. 

Such off-label uses are common across medical specialties. Although the FDA does not regulate the practice of medicine, the FDA does restrict 
our communications with respect to off-label use. We cannot promote FDA-approved drugs for off-label uses. A company may engage in 
truthful, non-misleading, and non-promotional speech concerning its products. For example, while we may inform physicians that we are 
conducting a clinical trial to evaluate the safety and effectiveness of IPLEX in unapproved uses and encourage those physicians to refer eligible 
patients to enroll in the clinical trial, we cannot promote the product for unapproved uses. We may also educate physicians about a particular 
disease state and how that disease is properly diagnosed so that patients who qualify for the clinical trial might be identified, and survey 
physicians  

36  

   
Table of Contents  

who are lawfully prescribing our products or competitors’ products for off-label uses to monitor patients’ experiences. We may also, pursuant 
to FDA policies, respond to unsolicited requests from health care professionals and engage in appropriate scientific exchange of information 
about unapproved uses. As we have no sales and marketing experience, we have not engaged in these lawful activities with respect to IPLEX in 
the past. These rules are complex and our sales and marketing employees may not understand the regulations against off-label promotion. We 
do not yet have policies and procedures in place to regulate the lawful promotion of our marketed products within their labeled indications. 
While our employees will be trained to follow specific policies and procedures designed to instruct the lawful promotion of our products and 
must certify that they will abide by them, we cannot guarantee that our employees will follow these policies and procedures. The FDA actively 
enforces regulations prohibiting promotion of off-label uses and the promotion of products for unapproved uses. The FDA’s regulations and 
policies are subject to varying interpretations, which are evolving. We cannot guarantee that we will change our policies as the FDA’s 
regulations and policies change. Failure to comply with these regulations and policies can result in regulatory enforcement action by the FDA 
and other governmental bodies, which would have an adverse effect on our revenues, business and financial prospects.  

Conversion of our outstanding notes and exercise of warrants and options issued by us will significantly dilute the ownership interest 
of existing shareholders.  

As of February 28, 2006, the convertible notes issued by us on March 15, 2005 and the warrants issued by us in March 2005, November 

2004 and July 2003 were convertible into and exercisable for up to approximately 13.2 million shares of our common stock, representing 
approximately 17% of our then outstanding common stock.  

As of February 28, 2006, our outstanding options to our employees, officers, directors and consultants were exercisable for up to 

6.1 million shares of our common stock, representing approximately an additional 8% of our then outstanding common stock.  

The conversion or exercise of some or all of our convertible notes, warrants and options will significantly dilute the ownership interests 
of existing shareholders. Any sales in the public market of the common stock issuable upon such conversion or exercise could adversely affect 
prevailing market prices of our common stock.  

The market price of our stock has been and may continue to be highly volatile, and we do not anticipate paying any cash dividends on 
our common stock in the foreseeable future.  

Our common stock is listed on The Nasdaq National Market under the ticker symbol “INSM.” The market price of our stock has been and 

may continue to be highly volatile, and announcements by us or by third parties may have a significant impact on our stock price. These 
announcements may relate to:  

• 

• 

• 

• 

• 

• 

• 

• 

• 

   our listing status on The Nasdaq National Market; 

   results of our clinical studies and preclinical studies, or those of our corporate partners or our competitors; 

   our operating results; 

   developments relating to patent or other litigation in which we are involved; 

   developments in our relationships with corporate partners; 

   developments affecting our corporate partners; 

   negative regulatory action or regulatory approval with respect to our announcement or our competitors’ announcements of new 

products, 

   government regulation, reimbursement changes and governmental investigation or audits related to us or to our products, 

   developments related to our patents or other proprietary rights or those of our competitors;

   changes in the position of securities analysts with respect to our stock; and/or 

   operating results below the expectations of public market analysts and investors. 

In addition, the stock market has from time to time experienced extreme price and volume fluctuations, which have particularly affected 

the market prices for emerging biotechnology and biopharmaceutical companies, and which have often been unrelated to their operating 
performance. These broad market fluctuations may adversely affect the market price of our common stock.  

In the past, when the market price of a stock has been volatile, holders of that stock have often instituted securities class action litigation 

against the company that issued the stock. If any of our shareholders brought a lawsuit against us, we could incur substantial costs defending 
the lawsuit. The lawsuit could also divert the time and attention of our management.  

Future sales by existing shareholders may lower the price of our common stock, which could result in losses to our shareholders. Future 
sales of substantial amounts of common stock in the public market, or the possibility of such sales occurring, could adversely affect prevailing 
market prices for our common stock or our future ability to raise capital through an offering of equity securities. Substantially all of our 
common stock is freely tradable in the public market without restriction under the Securities Act, unless these shares are held by “affiliates” of 
our company, as that term is defined in Rule 144 under the Securities Act.  

We have never paid dividends on our common stock. We currently intend to retain our future earnings, if any, to fund the development 

and growth of our businesses and, therefore, we do not anticipate paying any cash dividends in the foreseeable future.  

Certain provisions of Virginia law, our articles of incorporation and our amended and restated bylaws, and our Rights Plan make a 
hostile takeover by a third party difficult.  

Certain provisions of Virginia law and our articles of incorporation and amended and restated bylaws could hamper a third party’s 
acquisition of, or discourage a third party from attempting to acquire control of us. The conditions could also limit the price that certain 
investors might be willing to pay in the future for shares of our common stock. These provisions include:  

• 

   a provision allowing us to issue preferred stock with rights senior to those of the common stock without any further vote or action by 

the holders of the common stock. The issuance of preferred stock could decrease the amount of earnings and assets available for 
distribution to the holders of common stock or could adversely affect the rights and powers, including voting rights, of the holders of 
the common stock. In certain circumstances, such issuance could have the effect of decreasing the market price of the common stock; 

• 

   the existence of a staggered board of directors in which there are three classes of directors serving staggered three-year terms, thus 

expanding the time required to change the composition of a majority of directors and perhaps discouraging someone from making an 
acquisition proposal for us; 

• 

• 

• 

   the amended and restated bylaws’ requirement that shareholders provide advance notice when nominating our directors; 

   the inability of shareholders to convene a shareholders’ meeting without the chairman of the board, the president or a majority of the 

board of directors first calling the meeting; and 

   the application of Virginia law prohibiting us from entering into a business combination with the beneficial owner of 10% or more of 
our outstanding Voting stock for a period of three years after the 10% or greater owner first reached that level of stock ownership, 
unless we meet certain criteria. 

In addition, in May 2001, our board of directors approved the adoption of a Rights Plan under which shareholders received rights to 

purchase new shares of preferred stock if a person or group acquires 15% or more  

38

of our common stock. These provisions are intended to discourage acquisitions of 15% or more of our common stock without negotiations with 
the board. The rights trade with our common stock, unless and until they are separated upon the occurrence of certain future events. Our board 
of directors may redeem the rights at a price of $0.01 per right prior to the time a person acquires 15% or more of our common stock.  

Our common stock may be thinly traded from time to time, which means large transactions in our common stock may be difficult to 
conduct in a short time frame.  

On occasion, we have a low volume of daily trades in our common stock on The Nasdaq National Market. Any large transactions in our 

common stock may be difficult to conduct and may cause significant fluctuations in the price of our common stock.  

Our long term growth strategy may include acquiring complementary businesses or technologies that may not be available or, if 
available and purchased or licensed, might not improve our business, financial condition or results of operations.  

As part of our business strategy, we eventually expect to pursue acquisitions and in-license new products and technologies. Nonetheless, 

we cannot assure you that we will identify suitable acquisitions or products or that we can make such acquisitions or enter into such license 
agreements on acceptable terms. If we acquire businesses, those businesses may require substantial capital, and we cannot provide assurance 
that such capital will be available in sufficient amounts or that financing will be available in amounts and on terms that we deem acceptable. 
Furthermore, the integration of acquired businesses may result in unforeseen difficulties that require a disproportionate amount of 
management’s attention and our other resources. Finally, we cannot provide assurance that we will achieve productive synergies and 
efficiencies from these acquisitions.

Item 2. 

Properties 

Our Headquarters is located in Glen Allen, Virginia where we occupy approximately 46,000 square feet of space for corporate and 
development activities under a lease expiring in October 2006. Our annual cash cost for the Virginia space including utilities and services in 
2005 was approximately $1.3 million under an operating lease that contains annual escalations of 1.75% and expires in October 2006.  

Our manufacturing facility is located in Boulder, Colorado where we occupy approximately 25,000 square feet dedicated to cGMP 

production of commercial and clinical drug and quality control and 26,000 square feet of space in two adjacent facilities for additional 
laboratory and research and development operations, administrative functions, and cGMP warehouse and dispensing operations. Our annual 
cash cost for the Colorado manufacturing facility including utilities and services in 2005 was approximately $0.9 million under an operating 
lease that contains an annual escalation of 3% and expires in February 2008.  

We believe that our existing facilities are adequate for our current needs and that suitable additional or alternate space will be available on 

commercially reasonable terms when our lease expires or when we need additional space.  

Item 3. 

Legal Proceedings 

Infringement Claims  

We are currently defending infringement claims brought against us. On December 20, 2004, Tercica and Genentech filed a complaint 

against Avecia Limited and us in the United Kingdom at the High Court of Justice, Chancery Division, Patents Court alleging infringement of 
EP patent No. 571,417, or the ‘417 patent. The ‘417 patent has claims directed to particular uses of a combination of IGFBP-3 and IGF-1. In 
the complaint, Tercica asked the court for an injunction to restrain allegedly infringing activity, for a declaration that the ‘417 patent is valid 
and infringed, for an order requiring the delivery or destruction of allegedly infringing articles and materials and for an inquiry into possible 
economic damages. In May 2005, we filed for summary judgment to dismiss the complaint. Our motion for summary judgment was denied and 
a trial date in this litigation has not been set.  

In addition, on December 23, 2004, Genentech and Tercica sued us for infringement of U.S. Patent Nos., 5,187,151 and 6,331,414 in the 
United States District Court for the Northern District of California. These patents are directed to certain methods of using rhIGF-1/rhIGFBP-3 
and methods of producing rhIGF-1, respectively. On February 16, 2005, Tercica filed an amended complaint, adding an infringement allegation 
against us with respect to U.S. Patent No. 5,528,287, or the ‘287 patent. The claims of the ‘287 patent are directed to DNA encoding BP53 (i.e. 
IGFBP-3) and recombinant constructs, transformed host cells and methods for using the same. Genentech and Tercica claim that the production 
or use of IPLEX, a complex of rhIGF-1/rhIGFBP-3, will infringe these patents. We moved to dismiss the amended complaint for lack of 
jurisdiction and on other grounds. At a hearing on the motion on April 15, 2005, the court granted our motion and dismissed the case with leave 
for plaintiffs to refile the complaint. A second amended complaint was filed on April 22, 2005 by Genentech and Tercica against us that, 
among other things added Celtrix Pharmaceuticals, our wholly-owned subsidiary, as a defendant. We moved to dismiss the portion of the 
second amended complaint that relates to the ‘287 patent. On June 29, 2005, the Court denied our motion to dismiss. On July 14, 2005, we filed 
our answer and counterclaims, in which we denied infringement and sought a declaratory judgment that the asserted patents are not infringed, 
are invalid, and/or are unenforceable. The reply to the counterclaims by Genentech and Tercica was filed on August 5, 2005. On October 17, 
2005, Tercica and Genentech filed a third amended complaint adding Insmed Therapeutic Proteins, our wholly-owned subsidiary, as a 
defendant. The answer and counterclaims in response to the third amended complaint were filed by us on October 27, 2005. Briefing on patent 
claim construction issues and summary judgment motions is set to be completed by May 5, 2006, with a claim construction hearing scheduled 
for May 19, 2006. Discovery is ongoing and a trial date is scheduled for November 2006.  

40  

   
   
Table of Contents  

On May 27, 2005, Genentech and Tercica filed a motion for preliminary injunction seeking an order barring us, until trial, from making, 
using or selling IPLEX with respect to its allegations of infringement of U.S. Patent Nos. 6,331,414 and 5,187,151, and requesting that we be 
required to share any Orphan Drug Exclusivity it obtains with Tercica. We filed an opposition to the motion for a Preliminary Injunction on 
June 10, 2005. On June 16, 2005, Genentech and Tercica withdrew their motion for a preliminary injunction, but reserved the right to refile the 
motion for a preliminary injunction. We cannot predict whether Genentech and Tercica will seek a preliminary injunction at another time.  

Deceptive Promotional Statements and Unfair Business Practices Claims  

On December 6, 2005, Tercica filed a complaint against us in the United States District Court for the Northern District of California 
alleging we made deceptive promotional statements and engaged in unfair business practices related to Tercica’s product, Increlex, allegedly in 
violation of the California Business and Professions Code and the Federal Lanham Act. Tercica amended the complaint on December 15, 2005. 
Tercica is requesting injunctive and monetary relief.  

Although we deny any liability, no assurances can be given as to the outcome of this action. An unfavorable settlement or decision could 
affect our ability to make, use or sell our products, and would have a material adverse effect on our business, financial condition and results of 
operations. Any liability resulting from this action may exceed our financial resources. We have requested that the court dismiss the action on a 
number of bases, including that Tercica failed to state a claim under the Federal Lanham Act and the court lacks personal jurisdiction over us. 
We plan to seek attorneys’ fees from Tercica if the case is successfully concluded.  

We cannot predict with certainty the outcome of these proceedings. We note however, that an adverse ruling could materially and 

adversely impact our ability to make, use or sell our products.

On February 28, 2006, the last reported sale price for our common stock on the Nasdaq National Market was $2.47 per share. As of 

February 28, 2006, there were 585 holders of record of our common stock.  

We have never declared or paid dividends on our common stock. We anticipate that we will retain all earnings, if any, to support 
operations and to finance the growth and development of our business. Therefore, we do not expect to pay cash dividends in the foreseeable 
future. Any future determination as to the payment of dividends will be at the sole discretion of our board of directors and will depend on our 
financial condition, results of operations, capital requirements and other factors our board of directors deems relevant.  

Item 6. 

Selected Financial Data 

In the table below, we provide you with selected historical financial data. We have prepared this information using the consolidated 

financial statements of Insmed for the five years ended December 31, 2005. The financial statements for each of the five fiscal years ended 
December 31, 2005 have been audited by Ernst & Young LLP, independent registered public accounting firm. Ernst & Young LLP’s report on 
the consolidated financial statements for the year ended December 31, 2005, which appears elsewhere herein, includes an explanatory 
paragraph which describes an uncertainty about Insmed’s ability to continue as a going concern.  

When you read this selected historical financial data, it is important that you also read the historical financial statements and related notes 

in our annual and quarterly reports filed with the SEC, as well as “Management’s Discussion and Analysis of Financial Condition and Results 
of Operations” on pages 31 to 35.

Item 7. 

Management’s Discussion and Analysis of Financial Condition and Results of Operations 

The following discussion also should be read in conjunction with the Consolidated Financial Statements and notes thereto.  

Overview  

Insmed Incorporated is a biopharmaceutical company focused on the development and commercialization of drugs for the treatment of 

metabolic diseases and endocrine disorders. We concentrate our efforts on treatments of conditions for niche markets with unmet medical 
needs. Currently, our development activities involve drugs that modulate IGF-1 activity in the human body. Our lead product, IPLEX™ 
(mecasermin rinfabate [rDNA origin] injection), the only once-daily IGF-1 replacement therapy, has been approved for commercial sale by the 
FDA, and we are in the process of establishing our sales and marketing team to commence commercial sales of IPLEX in the United States in 
the second quarter of 2006. Our development efforts are now focused on expanding the label for IPLEX into other clinical indications where 
we have proof of concept for IGF-1 therapy. In addition, we are developing two other drug candidates, INSM-18 and rhIGFBP-3, which are in 
clinical development for treating cancer.  

On December 12, 2005, the FDA approved IPLEX for the treatment of growth failure in children with severe Primary IGF-1 deficiency 
or with growth hormone gene deletion who have developed neutralizing antibodies to growth hormone (Severe Primary IGFD). As an Orphan 
Drug, IPLEX is entitled to seven years of marketing exclusivity for the treatment of Severe Primary IGFD in the United States.  

We are preparing to commercially launch IPLEX in the United States for the treatment of Severe Primary IGFD. The initial target 
population is approximately 6,000 children. These children are cared for primarily by pediatric endocrinologists and we plan to initially target 
the top 400 pediatric endocrinologists with our own focused specialty sales force. We have already hired a management team for our sales, 
marketing, medical communications and managed care groups that will bring IPLEX to the market. IPLEX has a therapeutic profile that we 
believe will make it a commercial success. Our plans for 2006 include:  

• 

• 

• 

• 

• 

• 

• 

   Fully commercialize and market IPLEX for the treatment of Severe Primary IGFD; 

   Initiate clinical trials to expand IPLEX into additional niche indications; 

   Ramp up manufacturing capability in support of 2006/2007 commercialization of IPLEX; 

   Establish commercial activities consistent with FDA approval process; 

   Capitalize through debt/equity and partnership fees to sustain 2006/2007 operations; 

   Establish a partner or partners outside the U.S. for our products; and 

   Aggressively defend patent lawsuits and other litigation in the United States and United Kingdom. 

We have not been profitable and have accumulated deficits of approximately $254.7 million through December 31, 2005. We expect to 
incur significant additional losses for at least the next several years until such time as sufficient revenues are generated to offset expenses. In 
general, our expenditures may increase as development of our product candidates progresses. However, there will be fluctuations from period 
to period caused by differences in project costs incurred at each stage of development.  

With the approval of our first drug product, IPLEX, for the treatment of Severe Primary IGFD on December 12, 2005 we estimate the full 

cost of bringing this drug to market to be $270 million. The full cost and completion dates, through commercialization, of our non-IPLEX 
research and development projects, INSM-18 and rhIGFBP-3, cannot be estimated at this time.

Research and Development Activities  

We are engaged in the research and development of proposed drug products for the treatment of metabolic diseases and endocrine 
disorders. All of our research and development expenditures, whether conducted by our own staff or by external scientists on our behalf and at 
our expense, are recorded as expenses as incurred and amounted to approximately $128 million dollars for the period since inception, in 
November 1999, through December 31, 2005, and $7 million, $23 million and $22 million in the years ended December 31, 2003, 2004 and 
2005. Research and development expenses consist primarily of salaries and related expenses, costs to develop and manufacture products and 
amounts paid to contract research organizations, hospitals and laboratories for the provision of services and materials for drug development and 
clinical trials.  

Our leading product, IPLEX, was approved in December 2005 for the treatment of Severe Primary IGFD. IPLEX has also been granted 

Orphan Drug Designation for the treatment of Severe Primary IGFD indication and other indications. Substantially all of our research and 
development expenditures for fiscal 2004 and 2005 have been related to IPLEX.  

Our research and development efforts for other products are in their early stages and include primarily research and development 

regarding rhIGFBP-3 for the treatment of various cancers and INSM-18 for the treatment of various tumors. These products are either in 
preclinical stages or, Phase I and II clinical trials. All of our research and development expenditures related to these early-stage products and 
our efforts associated with IPLEX are significantly interrelated as they are all associated with drugs that modulate IGF-I activity in the human 
body. A significant finding in any one drug for a particular indication may provide benefits to our efforts across all of these products. All of 
these products also share a substantial amount of our common fixed costs such as salaries, facility costs, utilities and maintenance. Given the 
small portion of research and development expenses that are related to products other than IPLEX we have determined that very limited 
benefits would be obtained from implementing cost tracking systems that would be necessary to allow for cost information on a product-by-
product basis.  

In the near term, Insmed intends to focus substantially all of its research and development resources on the expansion of IPLEX into other 

indications. Our plans to expand IPLEX into additional indications are expected to represent our main research and development focus 
beginning in 2006. Our thrust to develop our other early-stage products will continue but we expect those efforts to account for a much smaller 
portion of Insmed’s research and development expenditures. These estimates are based on currently available information and, due to a number 
of factors, no assurance can be provided that this project will not take longer to complete or cost more than we have currently estimated.  

Our clinical trials with respect to IPLEX are subject to numerous risks and uncertainties that are outside of our control, including the 

possibility that necessary regulatory approvals may not be obtained. For example, the duration and the cost of clinical trials may vary 
significantly over the life of a project as a result of differences arising during the clinical trial protocol, including, among others, the following:  

• 

• 

• 

• 

• 

   the number of patients that ultimately participate in the trial; 

   the duration of patient follow-up that is determined to be appropriate in view of results; 

   the number of clinical sites included in the trials; 

   the length of time required to enroll suitable patient subjects; and 

   the efficacy and safety profile of the product candidate. 

45  

   
   
   
   
   
   
  
  
  
  
  
Table of Contents  

Our clinical trials may also be subject to delays or rejections based on our inability to enroll patients at the rate that we expect or our inability to 
produce clinical trial material in sufficient quantities and of sufficient quality to meet the schedule for our planned clinical trials.  

Moreover, all of our product candidates and particularly those that are in the preclinical or early clinical trial stage must overcome 
significant regulatory, technological, manufacturing and marketing challenges before they can be successfully commercialized. Some of these 
projects may never reach the clinical trial stage of research and development. As preclinical studies and clinical trials progress, we may 
determine that collaborative relationships will be necessary to help us further develop or to commercialize our product candidates, but such 
relationships may be difficult or impossible to arrange. Our projects or intended projects may also be subject to change from time to time as we 
evaluate our research and development priorities and available resources.  

Any significant delays that occur or additional expenses that we incur may have a material adverse affect on our financial position and 

require us to raise additional capital sooner or in larger amounts than is presently expected. In addition, as a result of the risks and uncertainties 
related to the development and approval of our drug candidates and the additional uncertainties related to our ability to market and sell these 
products once approved for commercial sale, we are unable to provide a meaningful prediction regarding the period in which material net cash 
inflows from any of these projects are expected to become available.  

Results of Operations  

Year Ended December 31, 2005 compared to Year Ended December 31, 2004  

For the year ended December 31, 2005, we recorded a net loss of $40.9 million. Research and development expenses (which consist 

primarily of costs associated with clinical trials of our product candidates, including the costs of manufacturing, compensation and other 
expenses related to research and development personnel and facilities expenses) decreased $1.4 million from $23.3 million in 2004 to $21.9 
million in 2005. This decrease in spending resulted from a winding-down of our clinical trials program offset by an increase in manufacturing 
activity at our ITP facility.  

General and administrative expenses increased $1.5 million from $4.2 million for 2004 to $5.7 million for 2005. The increase was due to 
higher external service and personnel costs in support of our business. Revenues decreased $6,000 from $137,000 in 2004 to $131,000 in 2005 
due to a slight decline in royalties.  

We recorded $14.2 million in interest expense for the twelve months ended December 31, 2005 as a result of the March 15, 2005 
convertible notes financing. Of this amount $13.1 million was non-cash as a result of the accelerated amortization of the debt discount as a 
result of the conversion of notes to common stock in the 3 rd and 4 th quarters of 2005. $5.0 million of unamortized debt discount remained in 
long-term liabilities on our balance sheet and is expected to be amortized over the remaining life of the notes.  

As of December 31, 2005, cash and cash equivalents increased to $18.8 million from $9.2 million at December 31, 2004. As a result of a 
higher average cash balance and higher interest rates in 2005 compared to 2004, interest income increased $530,000 from $222,000 in 2004 to 
$752,000 in 2005.  

Accounts payable and accrued project costs and other costs decreased $0.5 million from $3.5 million at December 31, 2004 to $3.0 
million at December 31, 2005 as a result of decreased clinical and manufacturing activity. $1.6 million of accrued project costs and other costs 
related to a duplicate deposit of warrant exercise money received that was returned by the company in January 2006. Stockholders’ equity 
increased $3.3 million mainly as a result of the convertible notes financing on March 15, 2005 in which the company received net proceeds of 
$32.6 million. This was offset by the net loss for the year of $40.9 million. The accumulated deficit at December 31, 2005 increased to 
approximately $254.7 million due to our 2005 net loss of $40.9 million.

Table of Contents  

Year Ended December 31, 2004 compared to Year Ended December 31, 2003  

For the year ended December 31, 2004, we recorded a net loss of $27.2 million. Research and development expenses (which consist 

primarily of costs associated with clinical trials of our product candidates, including the costs of manufacturing, compensation and other 
expenses related to research and development personnel and facilities expenses) increased $16.2 million from $7.1 million in 2003 to $23.3 
million in 2004. This rise in spending resulted from a broader clinical trials program and an increase in manufacturing activity at our ITP 
facility and at our contract manufacturer Avecia to produce IPLEX for our clinical trials,  

General and administrative expenses increased $0.7 million from $3.5 million for 2003 to $4.2 million for 2004. The increase was due to 

higher external service and personnel costs in support of our business. Revenues decreased $13,000 from $150,000 in 2003 to $137,000 in 
2004 due to a slight decline in royalties.  

As of December 31, 2004, cash and cash equivalents decreased to $9.2 million from $29.5 million at December 31, 2003. As a result of a 
lower average cash balance and lower interest rates in 2004 compared to 2003, net interest income decreased $66,000 from $288,000 in 2003 to 
$222,000 million in 2004.  

Accounts payable and accrued project costs increased $1.1 million from $2.4 million at December 31, 2003 to $3.5 million at 

December 31, 2004 as a result of increased clinical and manufacturing activity. Stockholders’ equity decreased $19.0 million mainly as a result 
of the net loss for 2004 of $27.2 million being partially offset by approximately $8.0 million in net proceeds received in connection with a 
private placement of our common stock on November 8, 2004. The accumulated deficit at December 31, 2004 increased to approximately 
$213.7 million due to our 2004 net loss of $27.2 million.  

Liquidity and Capital Resources  

There is considerable time and cost associated with developing a potential drug or pharmaceutical product to the point where FDA 
approval for sales is received. In our financial management, we seek to raise the funds necessary for such development primarily through the 
issuance of equity securities in private placement transactions. However, it is our intention to pursue additional financing options, including 
entering into agreements with corporate partners in order to provide milestone payments, license fees and equity investments.  

Capital Requirements  

Capital expenditures in the year ended December 31, 2005 were principally related to the research and development, increased clinical 
trial activity and manufacturing activities at our site in Boulder, Colorado, as well as administrative support activities. In the short-term, we will 
need to raise substantial additional funds to continue the commercialization and marketing of IPLEX. In the longer-term, we will require 
substantial additional funds for the continued development of our other lead drug products. We have filed a shelf registration statement with the 
SEC that allows us to sell up to $75,000,000 of its common stock, preferred stock or warrants for common or preferred stock. We may sell 
these securities in one or more separate offerings in amounts, at prices and on terms to be determined at the time of such offer or offerings. This 
shelf registration statement is intended to give us flexibility to take advantage of financing opportunities when and if deemed appropriate by us. 
Our continuation as a going concern depends on our ability to obtain such additional financing and, ultimately, to generate positive cash flow 
and attain profitability. There can be no assurance that adequate funds will be available when we need them or on favorable terms. If at any 
time we are unable to obtain sufficient additional funds, we will be required to delay, restrict or eliminate some or all of our research or 
development programs, dispose of assets or technology or cease operations.  

The registered public accounting firm report to our audited financial statements for the period ended December 31, 2005, indicates that 
there are a number of conditions that raise substantial doubt about our ability to continue as a going concern. Such conditions identified in the 
report are our net loss position, our failure to attain profitable operations and our dependence upon obtaining adequate financing.

Table of Contents  

Planned expenditures in 2006 include the funding of our ongoing research and development activity, such as manufacturing and clinical 

trial costs, general and administrative support costs plus commercialization efforts associated with our FDA approved drug, IPLEX.  

Capital Resources  

We have funded our operations to date primarily through public and private placements of equity securities. We plan to continue 
incurring losses as we expand our research and development and do not expect material revenues for at least the next several years. At 
December 31, 2005, our cash and cash investments were approximately $18.8 million and were invested in money market instruments. This is 
an increase from $9.2 million at December 31, 2004 as a result of the Convertible Notes financing described below.  

On March 15, 2005 (the Initial Closing Date), we issued and sold approximately $35,000,000 aggregate principal amount of 5.5% Senior 
Convertible Notes (the Notes) to a group of institutional investors, which Notes will be convertible into our common stock, par value $0.01 per 
share, and Warrants to purchase 14,864,865 shares of our common stock (the Warrants), at an exercise price of $1.36 per share. The Notes will 
convert into the Company’s Common Stock at a conversion price of $1.295 per share as adjusted in accordance with certain anti-dilution 
adjustments (the Conversion Price). The principal of each Note will mature and be payable in nine quarterly installments commencing on 
March 1, 2008 and ending on March 1, 2010. All outstanding Notes shall be repaid in cash or converted within five years after the Initial 
Closing Date. Interest on the Notes is payable quarterly. Upon conversion of the Notes, the related accrued and unpaid interest, if any, shall be 
paid in cash to the investor. The Warrants are exercisable for five years from the Initial Closing Date. Commencing two years after the Initial 
Closing Date, if the market value of our common stock closes above 200% of the Conversion Price for at least fifteen of twenty consecutive 
trading days and other specific criteria are met, we shall have the right on one occasion only to redeem 50% or more (on a pro rata basis) of the 
Notes at par, plus any related accrued interest. The investors have the right to require us to repurchase the Notes upon the occurrence of certain 
repurchase events set forth in the transaction agreements, including, but not limited to, the absence of trading or market prices, delisting, a 
fundamental change or certain actions that discriminate against the investors in regards to their interest in the common stock. The investors 
shall also have a right of participation in any future financings undertaken by us prior to March 16, 2006, which will permit the investors to 
purchase up to such portion of any subsequent equity or equity-linked financing, on the same terms and conditions as the other parties in the 
financing, as shall enable each investor to maintain its ownership percentage of the Company on a fully-diluted basis at such time.  

Our business strategy contemplates raising additional capital through equity sales. We also plan to enter into agreements with corporate 

partners in order to fund research and development and to provide milestone payments, license fees and equity investments to fund our 
operations.  

Off-Balance Sheet Arrangements  

We do not have any off-balance sheet arrangements that have or are reasonably likely to have a current or future effect on our financial 

condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources that we believe is material to 
investors.

December 31, 2005. These notes become due in quarterly installments beginning on March 8, 2008 if not converted to common shares at 
an earlier date. 

Critical Accounting Policies  

Preparation of financial statements requires us to make estimates and assumptions affecting the reported amounts of assets, liabilities, 
revenues and expenses and the disclosures of contingent assets and liabilities. We use our historical experience and other relevant factors when 
developing our estimates and assumptions. We continually evaluate these estimates and assumptions. The accounting policies discussed below 
are those we consider critical to an understanding of our consolidated financial statements because their application places the most significant 
demands on our judgment. Our financial results might have been different if different assumptions had been used or other conditions had 
prevailed. For additional accounting policies, see Note 1 to our consolidated financial statements – “Description of the Business and Summary 
of Significant Accounting Policies”  

Research and Development  

Research and development costs are expensed as incurred. Research and development expenses consist primarily of salaries and related 

expenses, cost to develop and manufacture products, patent protection costs and amounts paid to contract research organizations, hospitals and 
laboratories for the provision of services and materials for drug development and clinical trials. We do not have separate accounting policies for 
internal or external research and development and we do not conduct any research and development for others. Our expenses related to clinical 
trials are based on estimates of the services received and efforts expended pursuant to contracts with third party organizations that conduct and 
manage clinical trials on our behalf. These contracts set forth the scope of work to be completed at a fixed fee or amount per patient enrolled. 
Payments under these contracts depend on performance criteria such as the successful enrollment of patients or the completion of clinical trial 
milestones. Expenses are accrued based on contracted amounts applied to the level of patient enrollment and to activity according to the clinical 
trial protocol.  

Our expenses relating to contract manufacturing of clinical material are based on agreements reached with the contract manufacturer. The 

contract identifies the amount of clinical material to be manufactured, the time for manufacture, and other development work to be completed 
in supporting the manufacturing of the clinical material. In general, the contract and the work to be completed are in phases, and we accrue 
expenses for these contracts based upon the initiation and timing of each phase.  

Stock-Based Compensation  

We recognize expense for stock-based compensation in accordance with the provisions of Accounting Principles Board Opinion No. 25, 

Accounting for Stock Issued to Employees , and related interpretations.

Accordingly, compensation cost is recognized for the excess, if any, of the estimated fair value of the stock at the grant date over the exercise 
price. Disclosures regarding alternative fair value measurement and recognition methods prescribed by Financial Accounting Standards Board 
(“FASB”) Statement No. 123, Accounting for Stock-Based Compensation, as amended by FASB Statement No. 148, Accounting for Stock-
Based Compensation – Transition and Disclosure , are presented in Notes 1 and 2. The fair value for these awards was estimated at the date of 
grant using the Black-Scholes pricing method assuming a weighted average volatility, a risk-free interest rate, no dividends, and a weighted-
average expected life of the option.  

Stock options granted to non-employees are accounted for in accordance with the Emerging Issues Task Force (EITF) 96-18, Accounting 
for Equity Instruments that are issued to Other than Employees for Acquiring, or in Conjunction with Selling Goods or Services . Accordingly, 
the estimated fair value of the equity instrument is recorded on the earlier of the performance commitment date or the date the services required 
are completed.  

Item 7a. 

Quantitative and Qualitative Disclosures about Market Risk 

We invest excess cash in investment grade, interest-bearing securities and, at December 31, 2005, had $18.8 million invested in money 

market instruments. Such investments are subject to interest rate and credit risk. Our policy of investing in highly rated securities whose 
maturities at December 31, 2005, are all less than 3-months minimizes such risks. In addition, while a hypothetical 1.0% per annum decrease in 
market interest rates would reduce interest income in 2005, it would not result in a loss of the principal and the decline in interest income 
would be deemed immaterial. Our purpose in making these investments is to generate investment income.  

We currently do not transact any significant portion of our business in functional currencies other than the United States dollar. To the 

extent that we continue to transact its business using the United States dollar as our functional currency, we do not believe that the fluctuations 
in foreign currency exchange rates will have a material adverse effect on our results of operations.

The Board of Directors and Stockholders  
Insmed Incorporated  

Report of Independent Registered Public Accounting Firm  

We have audited the accompanying consolidated balance sheets of Insmed, Incorporated (the “Company”) as of December 31, 2005 and 
2004, and the related consolidated statements of operations, stockholders’ equity, and cash flows for each of the three years in the period ended 
December 31, 2005. These financial statements are the responsibility of the Company’s management. Our responsibility is to express an 
opinion on these financial statements based on our audits.  

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

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

In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of 
Insmed Incorporated at December 31, 2005 and 2004, and the consolidated results of its operations and its cash flows for each of the three 
years in the period ended December 31, 2005, in conformity with U.S. generally accepted accounting principles.  

The accompanying financial statements have been prepared assuming that Insmed Incorporated will continue as a going concern. As 

more fully described in Note 2, the Company has incurred recurring operating losses and has a net capital deficiency. These conditions raise 
substantial doubt about the Company’s ability to continue as a going concern. Management’s plans in regard to these matters are also described 
in Note 2. The financial statements do not include any adjustments to reflect the possible future effects on the recoverability and classification 
of assets or the amounts and classification of liabilities that may result from the outcome of this uncertainty.  

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the 

effectiveness of Insmed Incorporated’s internal control over financial reporting as of December 31, 2005, based on criteria established in 
Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report 
dated February 10, 2006 expressed an unqualified opinion thereon.

The Board of Directors and Stockholders  
Insmed Inc.  

Report of Independent Registered Public Accounting Firm  
on Internal Control over Financial Reporting  

We have audited management’s assessment, included in the accompanying “Report of Management on Insmed Incorporated’s Internal 

Control over Financial Reporting”, that Insmed Incorporated maintained effective internal control over financial reporting as of December 31, 
2005, based on criteria established in “Internal Control—Integrated Framework” issued by the Committee of Sponsoring Organizations of the 
Treadway Commission (the COSO criteria). Insmed Incorporated’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. Our responsibility is to express an 
opinion on management’s assessment and an opinion on the effectiveness of 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, 
evaluating management’s assessment, testing and evaluating the design and operating effectiveness of internal control, and performing such 
other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.  

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of 

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

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

In our opinion, management’s assessment that Insmed Incorporated maintained effective internal control over financial reporting as of 
December 31, 2005, is fairly stated, in all material respects, based on the COSO criteria. Also, in our opinion, Insmed Incorporated maintained, 
in all material respects, effective internal control over financial reporting as of December 31, 2005, based on the COSO criteria.  

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the 

consolidated balance sheets of Insmed Incorporated, as of December 31, 2005 and 2004, and the related consolidated statements of operations, 
stockholders’ equity and cash flows for the three years in the period ended December 31, 2005, and our report dated February 10, 2006, except 
for Note 10 as to which the date is February 28, 2006 expressed an unqualified opinion thereon.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS  

1.    Description of the Business and Summary of Significant Accounting Policies  

Insmed Incorporated (“Insmed” or “the Company”) is a biopharmaceutical company focused on the development and commercialization 

of drugs for the treatment of metabolic diseases and endocrine disorders in niche markets with unmet medical needs. Currently, our 
development and commercial activities involve drugs that modulate IGF-1 activity in the human body. Our FDA-approved lead product, 
IPLEX (mecasermin rinfabate [rDNA origin] injection), is the only once-daily IGF-1 replacement therapy. IPLEX was approved in December 
2005 and we are in the process of establishing our sales and marketing team to commence commercial sales in the United States in the second 
quarter of 2006. Our development efforts are now focused on expanding the label for IPLEX into additional clinical indications. In addition, we 
are continuing clinical trials for two other drug candidates, INSM-18 and rhIGFBP-3, which are in clinical development for the treatment of 
cancer.  

Principles of Consolidation  

The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries, Insmed Therapeutic 
Proteins, Insmed Pharmaceuticals, Incorporated and Celtrix Pharmaceuticals, Incorporated (“Celtrix”). All significant intercompany balances 
and transactions have been eliminated.  

Cash and Cash Equivalents  

The Company considers investments with maturities of three months or less when purchased to be cash equivalents.  

On April 14, 2004 the Company announced that it had acquired a lease to operate a recombinant protein manufacturing facility located in 

Boulder, Colorado. The Company intends to use the facility for the commercial manufacture of its FDA approved product, IPLEX. Insmed 
provided a Letter of Credit to the landlord of the Boulder facility in the amount of $1.3 million for prepayment of the outstanding lease term of 
4 years and a Letter of Credit to Baxter Healthcare Corporation for $2.1 million to cover facility restoration expenses on termination of the 
lease. These amounts are classified as restricted cash on the balance sheet. In connection with the aforementioned lease the Company has 
recorded an asset retirement obligation. Accretion expense for the years ended December 31, 2005 and 2004 totaled $0.6 million and 
$0.4 million respectively.  

Property and Equipment  

Depreciation is provided using the straight-line method over periods ranging from three to seven years. Property and equipment is stated 

at cost and consists of the following:  

Furniture and office equipment  

Accumulated depreciation  
Property and equipment, net

to the short-term maturities of these financial instruments. The carrying value of the net convertible debt is $6.4 million which approximates 
fair value. This is calculated using the intrinsic value of the conversion feature.  

Stock-Based Compensation  

The Company recognizes expense for stock-based compensation in accordance with the provisions of Accounting Principles Board 
Opinion No. 25, Accounting for Stock Issued to Employees , and related interpretations. Accordingly, compensation cost is recognized for the 
excess, if any, of the estimated fair value of the stock at the grant date over the exercise price. Disclosures regarding alternative fair value 
measurement and recognition methods prescribed by Financial Accounting Standards Board (“FASB”) Statement No. 123, Accounting for 
Stock-Based Compensation, are presented below. Stock options granted to non-employees are accounted for in accordance with EITF 96-18, 
Accounting for Equity Instruments that are issued to Other than Employees for Acquiring, or in Conjunction with Selling Goods or Services . 
Accordingly, the estimated fair value of the equity instrument is recorded on the earlier of the performance commitment date or the date the 
services required are completed.  

In accordance with FASB Statement No. 148, Accounting for Stock-Based Compensation—Transition and Disclosure (“SFAS 148”), the 

effect on net loss and net loss per share if the Company had applied the fair value recognition provisions of SFAS No. 123 to stock-based 
employee compensation is as follows:

The fair value for these awards was estimated at the date of grant using the Black-Scholes pricing method assuming a weighted average 

volatility of 89% in 2005, 89% in 2004, and 127% in 2003, a risk-free interest rate of 4.17% in 2005, 3.83% in 2004, and 3.0% in 2003, no 
dividends, and a weighted-average expected life of the option of 5 years in 2005, 5 years in 2004, and 4.93 years in 2003. Compensation 
expense for fixed awards with pro-rata vesting is recognized under the straight-line method.  

Revenue Recognition  

Revenue from license agreements is generally recognized over the term of the agreement, or in certain circumstances, when milestones 

are met. Amounts received for which there is a future performance obligation, are deferred and recognized on a straight-line basis over the life 
of the agreement.  

Research and Development  

Research and development costs are expensed as incurred. Research and development expenses consist primarily of salaries and related 

expenses, costs to develop and manufacture products, patent protection costs and

amounts paid to contract research organizations, hospitals and laboratories for the provision of services and materials for drug development and 
clinical trials.  

Income Taxes  

Income taxes are accounted for using the liability method. Deferred tax assets and liabilities are recognized for the future tax 

consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective 
tax bases and operating loss carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable 
income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and 
liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.  

Net Loss Per Share  

Basic net loss per share is computed based upon the weighted average number of common shares outstanding during the year. The 
Company’s diluted net loss per share is the same as its basic net loss per share because all stock options, warrants, and other potentially dilutive 
securities are antidilutive and, therefore, excluded from the calculation of diluted net loss per share.  

Segment Information  

The Company currently operates in one business segment, which is the development and commercialization of pharmaceutical products 

for the treatment of metabolic and endocrine diseases associated with insulin resistance. The Company is managed and operated as one 
business. A single management team that reports to the Chief Executive Officer comprehensively manages the entire business. The Company 
does not operate separate lines of business with respect to its products or product candidates. Accordingly, the Company does not have 
separately reportable segments as defined by FASB Statement No. 131, Disclosure about Segments of an Enterprise and Related Information .  

Use of Estimates  

The preparation of the consolidated financial statements in conformity with accounting principles generally accepted in the United States 

requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and 
accompanying notes. Actual results could differ from those estimates.  

Recent Accounting Pronouncements  

On December 16, 2004, the Financial Accounting Standards Board (FASB) issued a revision of Statement of Financial Accounting 
Standards No. 123 (revised 2005), Share-Based Payment (Statement 123(R)), which is a revision of FASB Statement No. 123, Accounting for 
Stock-Based Compensation. Statement 123(R) supersedes APB Opinion No. 25 “Opinion 25”, Accounting for Stock Issued to Employees, and 
amends FASB Statement No. 95, Statement of Cash Flows. Generally, the approach in Statement 123(R) is similar to the approach described in 
Statement 123. Statement 123(R) will be adopted by Insmed Incorporated on January 1, 2006.  

As permitted by Statement 123, Insmed currently accounts for share-based payments to employees using Opinion 25’s intrinsic value 
method and, as such, generally recognizes no compensation cost for employee stock options. However, Statement 123(R) requires all share-
based payments to employees, including grants of employee stock options, to be recognized in the income statement based on their fair values 
over the expected period of service.  

F-9  

   
   
Table of Contents  

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)  

INSMED INCORPORATED  

The full impact of adoption of Statement 123(R) cannot be predicted at this time because it will depend on levels of share-based 

payments granted in the future. However, had Insmed adopted Statement 123(R) in prior periods, the impact of that standard would have 
approximated the impact of Statement 123 as described in the disclosure of pro forma net income and earnings per share in this Note 1 to the 
consolidated financial statements. Statement 123(R) also requires the benefits of tax deductions in excess of recognized compensation cost to 
be reported as a financing cash flow, rather than as an operating cash flow as required under current literature. This requirement will reduce net 
operating cash flows and increase net financing cash flows in periods after adoption. Insmed is unable to estimate what those amounts will be 
in the future because they depend on, among other things, when employees exercise stock options.  

Operational Restructuring  

On September 10, 2002, the Company announced that it would immediately discontinue the internal development of one of its 
investigational drug candidates, INS-1, based on the results of the then recently completed Phase II clinical trials. At December 31, 2005, 
approximately $0.3 million of the related restructuring costs remain accrued in the current portion of the restructuring reserve. This balance is 
expected to closely approximate the remaining costs to be incurred by the Company for lease obligations. Lease termination costs are 
anticipated to extend through September 2006.  

2.    Risks and Uncertainties  

For the period from inception to December 31, 2005, the Company has accumulated a net loss of $255 million. The Company’s ability to 

continue as a going concern is dependent upon its ability to raise capital through securities offerings, debt financing, and partnerships and use 
these sources of capital to fund operations. Management is focusing on raising capital through any one or more of these options. There can be 
no assurance that any of management’s plans as described above will be successfully implemented or that the Company will continue as a 
going concern. Accordingly, there is substantial doubt regarding the Company’s ability to continue as a going concern.  

3.    Stockholders’ Equity  

Common Stock & Convertible Debt  

On March 15, 2005 (the Initial Closing Date), Insmed issued and sold approximately $35,000,000 aggregate principal amount of 5.5% 
Senior Convertible Notes (the Notes) to a group of institutional investors, which Notes will be convertible into our common stock, par value 
$0.01 per share, and Warrants to purchase 14,864,865 shares of our common stock (the Warrants), at an exercise price of $1.36 per share. The 
Notes will convert into 27,027,027 shares of the Company’s Common Stock at a conversion price of $1.295 per share as adjusted in accordance 
with certain anti-dilution adjustments (the Conversion Price). The principal of each Note will mature and be payable in nine quarterly 
installments commencing on March 1, 2008 and ending on March 1, 2010. All outstanding Notes shall be repaid in cash or converted within 
five years after the Initial Closing Date. Interest on the Notes is payable quarterly. Upon conversion of the Notes, the related accrued and 
unpaid interest, if any, shall be paid in cash to the investor. The Warrants are exercisable for five years from the Initial Closing Date. 
Commencing two years after the Initial Closing Date, if the market value of our common stock closes above 200% of the Conversion Price for 
at least fifteen of twenty consecutive trading days and other specific criteria are met, we shall have the right on one occasion only to redeem 
50% or more (on a pro rata basis) of the Notes at par, plus any related accrued interest. The investor has the right to require us to repurchase the 
Notes upon the occurrence of certain repurchase events set forth in the transaction agreements, including, but not limited to, the absence of 
trading or market prices, delisting, a fundamental change or certain actions that discriminate against  

F-10

the investors in regards to their interest in the common stock. The investors shall also have a right of participation in any future financings 
undertaken by us for one year, which will permit the investors to purchase up to such portion of any subsequent equity or equity-linked 
financing, on the same terms and conditions as the other parties in the financing, as shall enable each investor to maintain its ownership 
percentage of the Company on a fully diluted basis at such time. These proceeds were used during the year to fund operations. The total amount 
of deferred offering costs was $2.4 million. These are being amortized over the life of the notes using the effective interest method. The table 
below details our debt payments over the corresponding years.

Payments Due by Years 

Periodically, the Company has issued shares of common stock in exchange for services provided by shareholders and others. These 
issuances have been recorded at their estimated fair value at the time of the respective transactions and corresponding amounts have been 
reflected as expense in the accompanying consolidated statements of operations.  

Stock Warrants and Options  

The Company issues stock options to attract and retain executive officers, key employees, non-employee directors and other non-

employee advisors and service providers. The maximum number of shares issuable under the Company’s stock option plan is 9,250,000. 
Options may be granted at the discretion of the board of directors, compensation committee or a delegate. The weighted-average fair value of 
options granted during 2005, 2004, and 2003 was $1.29, $2.12, and $1.72, respectively. A summary of stock option activity is as follows:

A total of 22,732,514 shares of common stock were reserved at December 31, 2005 in connection with stock options, stock warrants, and 

the employee stock purchase plan.  

4.    Income Taxes  

The deferred tax assets of approximately $112.0 million and $104.2 million at December 31, 2005 and 2004, respectively, arise primarily 

due to net operating loss carryforwards for income tax purposes. Due to the Company’s anticipated future losses, these amounts have been 
entirely offset by a valuation allowance.  

At December 31, 2005 and 2004, the Company had net operating loss carryforwards for income tax purposes of approximately $278.2 
million and $261.0 million, respectively, expiring in various years beginning in 2006. Utilization of these carryforwards will be significantly 
limited due to changes in the ownership of the Company’s common stock.  

Deferred tax assets (liabilities) consist of the following at December 31:

abandonment of the lab space, the Company recognized $1.2 million of restructuring charge relating to this lease during the third quarter of 
2003. The Company also leases a manufacturing facility and warehouse in Boulder, Colorado under an operating lease agreement expiring in 
February 2008. The lease provides for monthly rent of approximately $30,000 with a 3% escalation per year. The Company also leases a 
vehicle and office equipment. Future minimum payments on all these leases at December 31, 2005 approximate $1,001,000, $365,000, $80,000 
and $14,000 in 2006, 2007, 2008, and 2009 respectively. Rent expense for all operating leases approximated $846,000 in 2005, $869,000 in 
2004, and $535,000 in 2003.  

6.    Employee Benefit Plans  

In 2000, the Company adopted a stock purchase plan whereby eligible employees may purchase common stock. Purchases may be made 

through payroll deductions subject to annual limitations. The purchase price per share under the plan is the lesser of 85% of the fair market 
value of a share of common stock at the beginning of each offering period or 85% of the fair market value on the date the purchase is made. As 
of December 31, 2005 there were 500,000 shares authorized for issuance under the plan and 317,818 had been issued.  

The Company also maintains a tax-qualified employee savings and retirement plan, (the “401(k) plan”) for eligible employees. 
Participating employees may defer up to the lesser of 25% of W-2 compensation or the maximum amount permitted by the Internal Revenue 
Code, as amended. The 401(k) plan permits the Company to make matching contributions on behalf of all participants who have elected to 
make deferrals. To date, the Company has not made any contributions to the plan.  

7.    License and Collaborative Agreements  

Fujisawa Pharmaceutical Co., Ltd.  

In January 2004, Insmed was granted a non-exclusive license to patent rights pertaining to the use of IGF-I therapy for the treatment of 

extreme or severe insulin resistant diabetes from Fujisawa Pharmaceutical Co., Ltd. Under the terms of the agreement, Insmed obtained 
worldwide rights in territories (excluding Japan) where a valid patent claim exists, including the United States and Europe. We have made a 
commitment to use reasonable commercial efforts to make IPLEX available on a named patient basis to patients with extreme insulin 
resistance.  

Pharmacia  

In August 2002 we entered into an agreement with Pharmacia that grants us an exclusive license to Pharmacia’s portfolio of regulatory 
filings pertaining to rhIGF-I. In consideration for the exclusive license we have agreed to make therapy available to the 17 Growth Hormone 
Insensitivity Syndrome subjects that were previously being treated with rhIGF-I supplied by Pharmacia.  

UVA Patent Foundation  

In 1988, the Company entered into a license agreement with The University of Virginia Alumni Patents Foundation (the “Foundation”). 
The agreement, as amended, provides the Company with an exclusive, worldwide license to develop and sell products related to certain patent 
rights for insulin resistance and associated disorders. The Company discontinued the development of products covered under this license and 
terminated this agreement on June 29, 2004.

9.    Legal Proceedings  

Infringement Claims  

We are currently defending infringement claims brought against us. On December 20, 2004, Tercica and Genentech filed a complaint 

against Avecia Limited and us in the United Kingdom at the High Court of Justice, Chancery Division, Patents Court alleging infringement of 
EP patent No. 571,417, or the ‘417 patent. The ‘417 patent has claims directed to particular uses of a combination of IGFBP-3 and IGF-1. In 
the complaint, Tercica asked the court for an injunction to restrain allegedly infringing activity, for a declaration that the ‘417 patent is valid 
and infringed, for an order requiring the delivery or destruction of allegedly infringing articles and materials and for an inquiry into possible 
economic damages. In May 2005, we filed for summary judgment to dismiss the complaint. Our motion for summary judgment was denied and 
a trial date in this litigation has not been set.  

In addition, on December 23, 2004, Genentech and Tercica sued us for infringement of U.S. Patent Nos., 5,187,151 and 6,331,414 in the 
United States District Court for the Northern District of California. These patents are directed to certain methods of using rhIGF-1/rhIGFBP-3 
and methods of producing rhIGF-1, respectively. On February 16, 2005, Tercica filed an amended complaint, adding an infringement allegation 
against us with respect to U.S. Patent No. 5,528,287, or the ‘287 patent. The claims of the ‘287 patent are directed to DNA encoding BP53 (i.e. 
IGFBP-3) and recombinant constructs, transformed host cells and methods for using the same. Genentech and Tercica claim that the production 
or use of IPLEX, a complex of rhIGF-1/rhIGFBP-3, will infringe these patents. We moved to dismiss the amended complaint for lack of 
jurisdiction and on other grounds. At a hearing on the motion on April 15, 2005, the court granted our motion and dismissed the case with leave 
for plaintiffs to refile the complaint. A second amended complaint was filed on April 22, 2005 by Genentech and Tercica against us that, 
among other things added Celtrix Pharmaceuticals, our wholly-owned subsidiary, as a defendant. We moved to dismiss the portion of the 
second amended complaint that relates to the ‘287 patent. On June 29, 2005, the Court denied our motion to dismiss. On July 14, 2005, we filed 
our answer and counterclaims, in which we denied infringement and sought a declaratory judgment that the asserted patents are not infringed, 
are invalid, and/or are unenforceable. The reply to the counterclaims by Genentech and Tercica was filed on August 5, 2005. On October 17, 
2005, Tercica and Genentech filed a third amended complaint adding Insmed Therapeutic Proteins, our wholly-owned subsidiary, as a 
defendant. The answer and counterclaims in response to the third amended complaint were filed by us on October 27, 2005. Briefing on patent 
claim construction issues and summary judgment motions is set to be completed by May 5, 2006, with a claim construction hearing scheduled 
for May 19, 2006. Discovery is ongoing and a trial date is scheduled for November 2006.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)  

INSMED INCORPORATED  

On May 27, 2005, Genentech and Tercica filed a motion for preliminary injunction seeking an order barring us, until trial, from making, 
using or selling IPLEX with respect to its allegations of infringement of U.S. Patent Nos. 6,331,414 and 5,187,151, and requesting that we be 
required to share any Orphan Drug Exclusivity it obtains with Tercica. We filed an opposition to the motion for a Preliminary Injunction on 
June 10, 2005. On June 16, 2005, Genentech and Tercica withdrew their motion for a preliminary injunction, but reserved the right to refile the 
motion for a preliminary injunction. We cannot predict whether Genentech and Tercica will seek a preliminary injunction at another time.  

Deceptive Promotional Statements and Unfair Business Practices Claims  

On December 6, 2005, Tercica filed a complaint against us in the United States District Court for the Northern District of California 
alleging we made deceptive promotional statements and engaged in unfair business practices related to Tercica’s product, Increlex, allegedly in 
violation of the California Business and Professions Code and the Federal Lanham Act. Tercica amended the complaint on December 15, 2005. 
Tercica is requesting injunctive and monetary relief.  

Although we deny any liability, no assurances can be given as to the outcome of this action. An unfavorable settlement or decision could 
affect our ability to make, use or sell our products, and would have a material adverse effect on our business, financial condition and results of 
operations. Any liability resulting from this action may exceed our financial resources. We have requested that the court dismiss the action on a 
number of bases, including that Tercica failed to state a claim under the Federal Lanham Act and the court lacks personal jurisdiction over us. 
We plan to seek attorneys’ fees from Tercica if the case is successfully concluded.  

Insmed cannot predict with certainty the outcome of these proceedings. Insmed notes however, that an adverse ruling could materially 

and adversely impact our ability to make, use or sell our products.  

10. Subsequent Events  

Between January 1, 2006 and February 28, 2006, Insmed received notices from holders of its 5.5% Convertible Notes due 2008 - 2010 

electing to voluntarily convert $5,425,000 principal amount of Convertible Notes into 4,189,189 shares of common stock at the conversion rate 
of one share of common stock for each $1.295 in principal amount of the Convertible Notes. The Company also received $8,810,402 from 
warrant exercises that resulted in 6,012,551 shares of common stock being issued at an exercise price of $1.36 and 370,370 shares of common 
stock being issued at an exercise price of $1.71.  

Following the conversions described above, $6,013,000 principal amount of the Convertible Notes remained outstanding. In addition, 

because certain of the Convertible Notes were converted prior to the March 1, 2006 quarterly interest payment, the Company issued an 
additional 29,800 shares of common stock for the forfeited cash interest payment at a conversion price of $1.295.

such loss, cost, damage or expense, the Security Deposit, without any interest thereon, shall be returned to Tenant within sixty (60) days after 
expiration of the Lease Term or as may be otherwise provided by law; provided, however, that Landlord may also deduct any amount from the 
Security Deposit Landlord estimates may be required to cover any shortfall in Additional Rent deposits made by Tenant in the final year of the

commencement of any Changes, Tenant shall post in conspicuous locations and maintain on the Demised Premises and Building Notices of 
Owner’s Non-Liability in the form attached hereto as Exhibit C or in such other form as Landlord may from time to time reasonably require in 
writing. Tenant shall have the right to contest, in good faith and with reasonable diligence, the validity of any such lien or claimed lien, 
provided that Tenant shall give to Landlord such security as may be reasonably requested by Landlord to insure the payment of any amounts 
claimed, including interest and costs, and to prevent any sale, foreclosure or forfeiture of any interest in the Property on account of any such 
lien, including, without limitation, bonding, escrow or endorsement of the title insurance policy of Landlord and any holder of a mortgage or 
deed of trust encumbering the Property. If Tenant so contests, then on final determination of the lien or claim for lien, Tenant shall immediately 
pay any judgment rendered, with interest and costs, if any, and will cause the lien to be released and any judgment satisfied.  

8.14 No Other Encumbrances . Tenant covenants and agrees not to obtain any financing secured by Tenant’s interest in the Demised 
Premises and not to encumber the Demised Premises or Landlord’s or Tenant’s interest therein, without the prior written consent of Landlord, 
and to keep the Demised Premises free from all liens and encumbrances except liens and encumbrances existing upon the date of 
commencement of the Lease Term or liens and encumbrances created by Landlord or otherwise outside the control of Tenant.  

8.15 Subordination to Landlord Mortgages . Tenant covenants and agrees that this Lease and Tenant’s interest in the Demised Premises 

shall be junior and subordinate to any mortgage or deed of trust now or hereafter encumbering the Property. In the event of a foreclosure of any 
such mortgage or deed of trust, Tenant shall attorn to the party acquiring title to the Property as the result of such foreclosure. No act or further 
agreement by Tenant shall be necessary to establish the subordination of this Lease to any such mortgage or deed of trust, which is self-
executing, but Tenant covenants and agrees, upon request to Landlord, to execute such documents as may be reasonably necessary or 
appropriate to confirm and establish this Lease as subordinate to any such mortgage or deed of trust in accordance with the foregoing 
provisions, including, without limitation, the form of Subordination, Non-Disturbance and Attornment Agreement attached hereto as Exhibit 
D . Alternatively, Tenant covenants and agrees that, at the option of any mortgagee or beneficiary under a deed of trust, Tenant shall execute 
documents as may be reasonably necessary to establish this Lease and Tenant’s interest in the Demised Premises as superior to any such 
mortgage or deed of trust. If Tenant fails to execute any documents required to be executed by Tenant under the provisions hereof, Tenant 
hereby makes, constitutes and irrevocably appoints Landlord as Tenant’s attorney in fact and in Tenant’s name, place and stead to execute any 
such document. In the event Tenant requests any changes or revisions to any such document or agreement, Tenant shall pay to Landlord, within 
ten (10) days after demand by Landlord, the reasonable costs and expenses of Landlord in connection with the negotiation, drafting, and 
revision thereof, including attorneys’ fees.  

12  

   
8.16 Assignment or Subletting . Tenant covenants and agrees not to make or permit a Transfer by Tenant, as hereinafter defined, without 

Landlord’s prior written consent, which consent shall not be unreasonably withheld, conditioned or delayed. A Transfer by Tenant shall include 
an assignment of this Lease, a sublease of all or any part of the Demised Premises or any assignment, sublease, license, franchise, transfer, 
mortgage, pledge or encumbrance of all or any part of Tenant’s interest under this Lease or in the Demised Premises, by operation of law or 
otherwise, or the use or occupancy of all or any part of the Demised Premises by anyone other than Tenant. Any such Transfer by Tenant 
without Landlord’s written consent shall be void and shall constitute a default under this Lease. In the event Landlord consents to any Transfer 
by Tenant, Tenant shall not be relieved of its obligations under this Lease and Tenant shall remain liable, jointly and severally and as a 
principal, and not as a guarantor or surety, under this Lease, to the same extent as though no Transfer by Tenant had been made, unless 
specifically provided to the contrary in Landlord’s prior written consent. The acceptance of rent by Landlord from any person other than Tenant 
shall not be deemed to be a waiver by Landlord of the provisions of this Section or of any other provision of this Lease and any consent by 
Landlord to a Transfer by Tenant shall not be deemed a consent to any subsequent Transfer by Tenant. In giving or withholding its consent to a 
proposed Transfer by Tenant, Landlord shall be entitled to consider any reasonable factor, including but not limited to the following: 
(a) financial strength and credit history of the proposed subtenant/assignee; (b) business reputation of the proposed subtenant/assignee; 
(c) proposed use of the Demised Premises by the proposed subtenant/assignee; (d) managerial and operational skills of the proposed 
subtenant/assignee; and (e) compatibility of the proposed subtenant with other tenants of the Building. Notwithstanding the foregoing, Tenant 
may assign this Lease or sublet any or all of its leasehold interest in the Demised Premises to an affiliate, subsidiary, or parent corporation of 
Tenant; (ii) resulting entity from a merger or consolidation involving Tenant; or (iii) an entity purchasing all or substantially all of the assets of 
Tenant, in each case without Landlord’s consent, provided that Tenant gives written notice to Landlord with a copy of the assignment or 
sublease and the assignee or sublessee agrees in writing with Landlord to be bound by the terms and conditions of the Lease; provided further 
that no such notice or consent shall be required in connection with the transfer of any voting stock or interests of Tenant. Despite any 
assignment or sublease, Tenant will not be relieved of its obligations under this Lease, and Tenant remains liable, jointly and severally and as a 
principal, and not as a guarantor or surety, under this Lease, to the same extent as though no assignment or sublease by Tenant had been made.  

Tenant covenants and agrees that in the event Landlord consents to a sublease by Tenant, Tenant and Tenant’s Subtenant shall enter 

into the form of Sublease, Assumption and Consent Agreement attached hereto as Exhibit E , and in the event Landlord consents to an 
assignment, Tenant and Tenant’s assignee shall enter into the form of Assignment, Assumption, and Consent Agreement attached hereto as 
Exhibit F , or the standard form of agreement in each case then being used by Landlord for subleases and assignments. In the event Tenant or 
Tenant’s transferee requests any changes or revisions to any such agreement, Tenant shall pay to Landlord, within ten (10) days after demand 
by Landlord, the reasonable costs and expenses of Landlord in connection with any request by Tenant for consent to a Transfer, including 
attorneys’ fees.  

8.17 Annual Financial Statements . Tenant covenants and agrees to furnish to Landlord, within fifteen (15) days after Landlord’s written 

request, copies of Tenant’s most recent year end financial statements, and agrees that Landlord may deliver any such financial statements to 
any existing or prospective mortgagee or purchaser of the Property. The financial statements shall include a balance sheet as of the end of, and 
a statement of profit and loss for, the preceding fiscal year of Tenant and, if regularly prepared by Tenant, a statement of sources and use of 
funds for the preceding fiscal year of Tenant.  

13  

   
8.18 Payment of Other Taxes . Tenant covenants and agrees to pay promptly when due all personal property taxes on personal property of 

Tenant on the Demised Premises and all state and local sales taxes and use taxes, the nonpayment of which might give rise to a lien on the 
Demised Premises or Tenant’s interest therein to the extent applicable to the Demised Premises, and to furnish, if requested by Landlord, 
evidence of such payments.  

8.19 Estoppel Certificates . Tenant covenants and agrees to execute, acknowledge and deliver to Landlord, upon Landlord’s written 
request, a written Estoppel Certificate certifying that this Lease is unmodified (or, if modified, stating the modifications) and in full force and 
effect; stating the dates to which Basic Rent has been paid, stating the amount of the Security Deposit held by Landlord; stating the amount of 
the Monthly Deposits held by Landlord for the then tax and insurance year; and stating whether or not Landlord is in default under this Lease 
(and, if so, specifying the nature of the default); and stating such other matters concerning this Lease as Landlord may reasonably request, 
including but not limited to, the form of Estoppel Certificate attached hereto as Exhibit G . Tenant agrees that such statement may be delivered 
to and relied upon by any existing or prospective mortgagee or purchaser of the Property. Tenant agrees that a failure to deliver such a 
statement within ten (10) days after written request from Landlord shall be conclusive upon Tenant that this Lease is in full force and effect 
without modification except as may be represented by Landlord; that there are no uncured defaults by Landlord under this Lease; and that any 
representation by Landlord with respect to Basic Rent, the Security Deposit and Monthly Deposits are true. In the event Tenant requests any 
changes or revisions to any such Estoppel Certificate other than to correct inaccuracies, Tenant shall pay to Landlord, within ten (10) days after 
demand by Landlord, the reasonable costs and expenses of Landlord in connection the negotiation, drafting and revision of such Estoppel 
Certificate, including attorneys’ fees.

showing the Demised Premises to any existing or prospective mortgagee, purchaser or, during the last nine (9) months of the Lease Term, 
lessee of the Property or the Demised Premises. Except in the case of emergency, Landlord will notify Tenant a reasonable time prior to 
entering the Demised Premises. Tenant covenants and agrees that Landlord may at any time place on the Property or the Demised Premises a 
sign advertising the Property or the Demised Premises for sale or, within the last nine (9) months of the Term, for lease.  

8.21 Landlord Right to Renovate, Expand or Modify Building . Tenant covenants and agrees that Landlord shall have the right to 

renovate, expand, reconstruct, or otherwise modify the Building and/or Common Facilities at any time, in Landlord’s sole discretion; provided, 
however, that no such renovation, expansion, reconstruction, or other modification shall permanently or materially interfere with Tenant’s right 
to the quiet use and enjoyment of the Demised Premises. Landlord will give Tenant prior written notice describing any work planned under the 
terms of this provision and the methods planned for performing such work. Tenant may require Landlord to modify its methods in reasonable 
manner to minimize any impact on Tenant’s operations.  

8.22 Landlord Title to Fixtures, Improvements and Equipment . Subject to Tenant’s Restoration Obligations and excluding Tenant’s 
Equipment, Tenant covenants and agrees that all fixtures and improvements on the Demised Premises and all equipment and personal property 
relating to the use and operation of the Demised Premises (as distinguished from operations incident to the business of Tenant), including all 
plumbing, heating, lighting, electrical and air conditioning fixtures and equipment, whether or not attached to or affixed to the Demised 
Premises, and whether now or hereafter located upon the Demised Premises, shall be and remain the property of Landlord upon expiration of 
the Lease Term.  

14  

   
8.23 Removal of Tenant’s Equipment . In addition to Tenant’s Restoration Obligations, Tenant covenants and agrees to remove, at or 
prior to the expiration of the Lease Term, all of Tenant’s Equipment, as herein defined. If such removal shall injure or damage the Demised 
Premises Tenant covenants and agrees, at its sole cost and expense, at or prior to the expiration of the Lease Term, to repair such injury and 
damage in good and workmanlike fashion and to place the Demised Premises in the same condition as the Demised Premises would have been 
if such Tenant’s Equipment had not been installed. If Tenant fails to remove any Tenant’s Equipment by the Expiration of the Lease Term, 
Landlord may, at its option, keep and retain any such Tenant’s Equipment or dispose of the same and retain any proceeds therefrom, and 
Landlord shall be entitled to recover from Tenant any costs or expenses of Landlord in removing the same and in restoring the Demised 
Premises in excess of the actual proceeds, if any, received by Landlord from disposition thereof. Tenant releases and discharges Landlord from 
any and all claims and liabilities of any kind arising out of Landlord’s disposition of Tenant’s Equipment pursuant to this Section 8.23.  

8.24 Tenant Indemnification of Landlord . Tenant covenants and agrees to protect, indemnify, defend, and hold Landlord harmless from 
and against all liability, obligations, claims, damages, penalties, causes of action, costs and expenses, including attorneys’ fees, imposed upon, 
incurred by or asserted against Landlord by reason of: (a) any accident, injury to or death of any person or loss of or damage to any property 
occurring on the Demised Premises or Common Facilities; (b) any act or omission of Tenant or of Tenant’s officers, employees, agents, guests

the foregoing, Tenant will, at Tenant’s sole cost and expense, pay all costs and expenses to defend Landlord in any such action, suit or 
proceeding with counsel of Landlord’s choosing. Tenant’s obligations under this Section 8.24 will not apply to any liability, obligations, 
claims, damages, penalties, causes of action, costs and expenses, including attorneys’ fees, imposed upon, incurred by or asserted against 
Landlord to the extent caused or contributed by the gross negligence or willful misconduct of Landlord or its officers, agents, contractors, 
guests, invitees or employees.  

8.25 Liability of Landlord . Landlord shall be liable to Tenant for Landlord’s gross negligence and willful misconduct. Tenant waives and 

releases any claims Tenant may have against Landlord or Landlord’s officers, agents or employees for loss, damage or injury to person or 
property sustained by Tenant or Tenant’s officers, agents, employees, guests, invitees, or anyone claiming by, through or under Tenant 
resulting from any cause whatsoever other than gross negligence or willful misconduct. Notwithstanding anything to the contrary contained in 
this Lease, Landlord, its beneficiaries, successors and assigns, shall not be personally liable with respect to any of the terms, covenants and 
conditions of this Lease, and Tenant shall look solely to the equity of Landlord in the Property in the event of any default or liability of 
Landlord under this Lease, such exculpation of liability to be absolute and without any exception whatsoever.

agrees that Landlord shall be released from all obligations of Landlord under this Lease, except obligations that arose and matured prior to such 
transfer by Landlord; that Tenant shall thereafter look solely to Landlord’s successor or assign for satisfaction of the obligations of Landlord 
under this Lease; and that, upon demand by Landlord or Landlord’s successor or assign, Tenant shall attorn to such successor or assign.  

8.27 Rules and Regulations . Upon and after receipt of written notice thereof to Tenant, Tenant shall observe and comply with rules and 
regulations that may be promulgated and amended from time to time by Landlord, provided that such rules and regulations are reasonable and 
do not materially interfere with Tenant’s ability to carry out the Permitted Use at the Demised Premises. Landlord shall not be responsible to 
Tenant for the failure of any other tenant of the Building to observe or comply with any of the rules or regulations, but Landlord shall make 
reasonable efforts to enforce the rules and regulations (if any) for the benefit of all tenants of the Building.  

8.28 Monitoring Equipment . Should equipment for monitoring fire systems and/or security systems be deemed necessary by Tenant or 

be required for the Demised Premises by federal, state, or local governing agencies because of Tenant’s equipment, the nature of Tenant’s 
business, or Tenant’s modification of the Demised Premises, Tenant shall be responsible for installation of such monitoring system, for any 
required building permits, monthly monitoring fees, and any fines, penalties or other charges for false alarms. Should such monitoring systems 
be otherwise required by federal, state, or local governing agencies, or deemed by Landlord to be advisable for the operation of the Building,

ARTICLE 10  
DAMAGE OR DESTRUCTION  

10.1 Damage to Demised Premises . If any portion of the Demised Premises shall be damaged or destroyed by fire or other casualty, 

Tenant shall give prompt written notice thereof to Landlord (“Tenant’s Notice of Damage”).  

10.2 Options to Terminate if Damage to Demised Premises is Substantial . Upon receipt of Tenant’s Notice of Damage, Landlord shall 

promptly proceed to determine the nature and extent of the damage or destruction and to estimate the time necessary to repair or restore the 
Demised Premises. As soon as reasonably possible, Landlord shall give written notice to Tenant stating Landlord’s estimate of the time 
necessary to repair or restore the Demised Premises (“Landlord’s Notice of Repair Time”). If Landlord reasonably estimates that repair or 
restoration of the Demised Premises cannot be completed within two hundred forty (240) days from the time of Landlord’s Notice of Repair 
Time, Landlord and Tenant shall each have the option to terminate this Lease. If, however, the damage or destruction was caused by the act or 
omission of Tenant or Tenant’s officers, employees, agents, guests or invitees or of anyone claiming by, through or under Tenant and for any 
reason the casualty is not insured (except failure  

19  

   
by Landlord to have policy in force), Landlord shall have the option to terminate this Lease if Landlord reasonably estimates that the repair or 
restoration cannot reasonably be completed within two hundred forty (240) days from the time of Tenant’s Notice of Damage, but Tenant shall 
not have the option to terminate this Lease. Any option granted hereunder shall be exercised by written notice to the other party given within 
ten (10) days after Landlord’s Notice of Repair Time. If either Landlord or Tenant exercises its option to terminate this Lease, the Lease Term 
shall expire thirty (30) days after the notice by either Landlord or Tenant exercising such party’s option to terminate this Lease. Following 
termination of this Lease under the provisions hereof, Landlord shall refund to Tenant such amounts of Basic Rent and Additional Rent 
theretofore paid by Tenant as may be applicable to the period subsequent to the time of Tenant’s Notice of Damage less the reasonable value of 
any use or occupation of the Demised Premises by Tenant subsequent to the time of Tenant’s Notice of Damage.  

10.3 Damage to Building . If the Building shall be damaged or destroyed by fire or other casualty (whether or not the Demised Premises 

are affected) to the extent of fifty percent (50%) or more of the replacement value of the Building, and within thirty (30) days after the 
happening of such damage Landlord shall decide not to reconstruct or rebuild the Building, then upon written notice to Tenant within such 
thirty (30) days, this Lease shall terminate and Landlord shall refund to Tenant such amounts of Basic Rent and Additional Rent paid by Tenant 
for the period after such damage less the reasonable value of any use or occupation of the Demised Premises by Tenant during such period.  

10.4 Obligations to Repair and Restore . If repair and restoration of the Demised Premises can be completed within the period specified in 

Section 10.2, in Landlord’s reasonable estimation, or if neither Landlord nor Tenant terminate this Lease as provided in Sections 10.2 or 10.3, 
this Lease shall continue in full force and effect and Landlord shall proceed forthwith to cause the Demised Premises to be repaired and 
restored with reasonable diligence and there shall be an abatement of Basic Rent and Additional Rent proportionate to the extent of the space 
and period of time that Tenant is unable to use and enjoy the Demised Premises. Landlord may, at its option, require Tenant to arrange for and 
supervise the repair and restoration of the Demised Premises, in which case Landlord shall furnish Tenant with the insurance proceeds for such 
repair and restoration at the time or times such funds are needed, provided that such proceeds are sufficient to cover the costs of repair or 
restoration.  

10.5 Application of Insurance Proceeds . The proceeds of any Casualty Insurance maintained on the Demised Premises, other than 
casualty insurance maintained by Tenant on fixtures and personal property of Tenant, shall be paid to and become the property of Landlord, 
subject to any obligation of Landlord to cause the Demised Premises to be repaired and restored and further subject to any rights of a holder of 
a mortgage or deed of trust encumbering the Property to such proceeds. Landlord’s obligation to repair and restore the Demised Premises 
provided in this Article 10 is limited to the repair and restoration that can be accomplished with the proceeds of any Casualty Insurance 
maintained or to be maintained on the Demised Premises; provided, that, if Landlord fails to repair and restore the Improvements, including the 
Demised Premises, for any reason, including the foregoing limitation, then Tenant shall have the right to terminate this lease upon written 
notice to Landlord, in which case Landlord shall refund to Tenant such amounts of Basic Rent and Additional Rent theretofore paid by Tenant 
as may be applicable to the period subsequent to the time of termination less the reasonable value of any use or occupation of the Demised 
Premises by Tenant subsequent to the date of casualty. Landlord will be responsible for any deductible on the Building casualty insurance 
maintained by Landlord; provided, however, that if the casualty results from an act or omission of Tenant, or Tenant’s officers, employees, 
agents, guests, or invitees or of anyone claiming by, through or under Tenant, then Tenant shall pay such deductible. The amount of any such 
insurance proceeds is subject to any right of a holder of a mortgage or deed of trust encumbering the Property to apply such proceeds to its 
secured debt.

CONDEMNATION  

11.1 Taking — Substantial Taking — Insubstantial Taking . A “Taking” shall mean the taking of all or any portion of the Demised 
Premises as a result of the exercise of the power of eminent domain or condemnation for public or quasi-public use or the sale of all or part of 
the Demised Premises under the threat of condemnation. A “Substantial Taking” shall mean a Taking of twenty five percent (25%) or more of 
the area (in square feet) of either the Demised Premises or the Building. An “Insubstantial Taking” shall mean a Taking that does not constitute 
a Substantial Taking.  

11.2 Termination on Substantial Taking . If there is a Substantial Taking with respect to the Demised Premises or the Building, the Lease 

Term shall expire on the date of vesting of title pursuant to such Taking. In the event of termination of this Lease under the provisions hereof, 
Landlord shall refund to Tenant such amounts of Basic Rent and Additional Rent theretofore paid by Tenant as may be applicable to the period 
subsequent to the time of termination of this Lease.  

11.3 Restoration on Insubstantial Taking . In the event of an Insubstantial Taking, this Lease shall continue in full force and effect, 
Landlord shall proceed forthwith to cause the Demised Premises, less such Taking, to be restored as near as may be to the original condition 
thereof and there shall be abatement of Basic Rent and Additional Rent proportionate to the extent of the space so taken. Landlord may, at its 
option, require Tenant to arrange for and handle the restoration of the Demised Premises, in which case Landlord shall furnish Tenant with 
sufficient funds for such restoration at the time or times such funds are needed.  

11.4 Right to Award . The total award, compensation, damages or consideration received or receivable as a result of a Taking (“Award”) 
shall be paid to and be the property of Landlord, including, without limitation, any part of the Award made as compensation for diminution of 
the value of the leasehold or the fee of the Demised Premises. Tenant hereby assigns to Landlord, all of Tenant’s right, title and interest in and 
to any such Award. Tenant covenants and agrees to execute, immediately upon demand by Landlord, such documents as may be necessary to 
facilitate collection by Landlord of any such Award. Notwithstanding Landlord’s right to the entire Award, Tenant shall be entitled to any 
separate award, if any, for the loss of Tenant’s personal property, Tenant’s relocation expenses, or the loss of Tenant’s business and profits.  

ARTICLE 12  
DEFAULTS BY TENANT  

The occurrence of any one or more of the following events shall constitute a “Default by Tenant” of this Lease:  

12.1 Failure to Pay Rent or Other Amounts . A Default by Tenant shall exist if Tenant fails to pay Monthly Rental (or any portion 
thereof), Basic Rent, Additional Rent, Monthly Deposits, or any other amounts payable by Tenant under the terms of this Lease, within five 
(5) days after (i) such rental or amount is due or (ii) notice that payment is due by Landlord to Tenant, whichever is later.  

12.2 Nonoccupancy of Demised Premises . A Default by Tenant shall exist if Tenant shall fail to occupy and use the Demised Premises 
within thirty (30) days after commencement of the Lease Term or shall leave the Demised Premises continuously unoccupied and shall vacate 
and abandon the Demised Premises without providing for ongoing maintenance, heating and other utility service to the Demised Premises 
while vacated.  

21  

   
12.3 Transfer of Interest Without Consent . A Default by Tenant shall exist if Tenant’s interest under this Lease or in the Demised 
Premises shall be transferred to or pass to or devolve upon any other party without Landlord’s prior written consent; provided, however, that 
this Section 12.3 shall not apply to assignments or subleases for which prior written consent is not required pursuant to Section 8.16 above.  

12.4 Execution and Attachment Against . A Default by Tenant shall exist if Tenant’s interest under this Lease or in the Demised Premises 

shall be taken upon execution or by other process of law directed against Tenant (other than by condemnation), or shall be subject to any 
attachment at the instance of any creditor or claimant against Tenant and said attachment shall not be discharged or disposed of within thirty 
(30) days after the levy thereof.  

12.5 Bankruptcy or Related Proceedings . A Default by Tenant shall exist if Tenant shall file a petition in bankruptcy or insolvency or for 

reorganization or arrangement under the bankruptcy laws of the United States or under any similar act of any state, or shall voluntarily take 
advantage of any such law or act by answer or otherwise, or shall be dissolved or shall make an assignment for the benefit of creditors or if 
involuntary proceedings under any such bankruptcy or insolvency law or for the dissolution of Tenant shall be instituted against Tenant or a 
receiver or trustee shall be appointed for the Demised Premises or for all or substantially all of the property of Tenant, and such proceedings 
shall not be dismissed or such receivership or trustee-ship vacated within sixty (60) days after such institution or appointment.  

12.6 Violation of Lease Terms . A Default by Tenant shall exist if Tenant breaches or fails to comply with any agreement, term, covenant 

or condition in this Lease applicable to Tenant (other than those referred to in Sections 12.1 through 12.5 above), and Tenant does not cure 
such breach or failure within thirty (30) days after notice thereof by Landlord to Tenant, or, if such breach or failure to comply cannot be 
reasonably cured within such 30-day period, if Tenant shall not in good faith commence to cure such breach or failure to comply with such 30-
day period or shall not diligently proceed therewith to completion with one hundred twenty (120) days following the occurrence of the breach 
or failure.  

12.7 Reserved .  

ARTICLE 13  
LANDLORD’S REMEDIES  

13.1 Remedies Generally. Upon the occurrence of any Default by Tenant, Landlord shall have the right, at Landlord’s election, then or at 

anytime thereafter, to exercise any one or more of the following remedies:  

13.1.1 Cure by Landlord . In the event of a Default by Tenant, Landlord may, at Landlord’s option, but without obligation to do so, 

and without releasing Tenant from any obligations under this Lease, make any payment or take any action as Landlord may reasonably deem 
necessary or desirable to cure any such Default by Tenant in such manner and to such extent as Landlord may reasonably deem necessary or 
desirable. Landlord may do so without demand on, or written notice to, Tenant and without giving Tenant any opportunity to cure such Default 
by Tenant. Tenant covenants and agrees to pay to Landlord, within ten (10) days after demand, all advances, costs and expenses of Landlord in 
connection with the making of any such payment or the taking of any such action, including reasonable attorneys’ fees, together with interest as 
hereinafter provided from the day of payment of any such reasonable advances,  

22  

   
costs and expenses by Landlord. Action taken by Landlord may include commencing, appearing in, defending or otherwise participating in any 
action or proceedings and paying, purchasing, contesting or compromising any claim, right, encumbrance, charge or lien with respect to the 
Demised Premises that is reasonably necessary or desirable to protect its interest in the Demised Premises and under this Lease.  

13.1.2 Termination of Lease and Damages . In the event of a Default by Tenant, Landlord may terminate this Lease, effective at 
such time as may be specified by written notice to Tenant, and demand (and, if such demand is refused, recover) possession of the Demised 
Premises from Tenant. Tenant shall remain liable to Landlord for damages in an amount equal to the Basic Rent, Additional Rent and other 
sums that would have been owing by Tenant hereunder for the balance of the term, had this Lease not been terminated, less the net proceeds, if 
any, of reletting of the Demised Premises by Landlord subsequent to such termination, after deducting all Landlord’s reasonable expenses in 
connection with such recovery of possession or reletting. Landlord shall be entitled to collect and receive such damages from Tenant on the 
days on which the Basic Rent, Additional Rent and other amounts would have been payable if this Lease had not been terminated. 
Alternatively, at the option of Landlord, Landlord shall be entitled to recover forthwith from Tenant, as damages for loss of the bargain and not 
as a penalty, an aggregate sum that, at the time of such termination of this Lease, represents the excess, if any, of (a) the aggregate of the Basic 
Rent, Additional Rent and all other sums payable by Tenant hereunder that would have accrued for the balance of the Lease Term, over (b) the 
aggregate rental value of the Demised Premises for the balance of the Lease Term, both discounted to present worth at the then applicable 
federal rate.  

13.1.3 Repossession and Reletting . In the event of Default by Tenant, Landlord may reenter and take possession of the Demised 

Premises or any part thereof, without demand or notice, and repossess the same and expel Tenant and any party claiming by, under or through 
Tenant, and remove the effects of both, without breach of the peace, without being liable for prosecution on account thereof or being deemed 
guilty of any manner of trespass, and without prejudice to any remedies for arrears of rent or right to bring any proceeding for breach of 
covenants or conditions. No such reentry or taking possession of the Demised Premises by Landlord shall be construed as an election by 
Landlord to terminate this Lease unless a written notice of such intention is given to Tenant. No notice from Landlord hereunder or under a 
forcible entry and detainer statute or similar law shall constitute an election by Landlord to terminate this Lease unless such notice specifically 
so states. Landlord reserves the right, following any reentry or reletting, to exercise its right to terminate this Lease by giving Tenant such 
written notice, in which even the Lease will terminate as specified in said notice. After recovering possession of the Demised Premises, 
Landlord may, from time to time, but shall not be obligated to, relet the Demised Premises, or any part thereof, for the account of Tenant, for 
such term or terms and on such conditions and upon such other terms as Landlord, in its uncontrolled discretion, may determine. Landlord may 
make such repairs, alterations or improvements as Landlord may consider appropriate to accomplish such reletting, and Tenant shall reimburse 
Landlord upon demand for all costs and expenses, including brokers’ commissions and attorneys’ fees, that Landlord may incur in connection 
with such reletting. Landlord may collect and receive the rents for such reletting but Landlord shall in no way be responsible or liable for any 
failure to relet the Demised Premises, or any part thereof, or for any failure to collect any rent due upon such reletting. Notwithstanding 
Landlord’s recovery of possession of the Demised Premises, Tenant shall continue to pay on the dates herein specified, the Basic Rent, 
Additional Rent and other amounts that would be payable hereunder if such repossession had not occurred. Upon the expiration or earlier 
termination of this Lease, Landlord shall refund to Tenant any amount, without interest, by which the amounts paid by Tenant, when added to 
the net amount, if any, recovered by Landlord through any reletting of the Demised Premises, exceeds the amounts payable by Tenant under 
this Lease. If, in connection with any reletting, the new lease term extends beyond the existing term, or the premises covered thereby include 
other premises not part of the Demised Premises, a fair apportionment of the rent received from such reletting and the expenses incurred in 
connection therewith will be made in determining the net amount recovered from such reletting.  

23  

   
13.1.4 Waiver of Landlord Liens . Landlord hereby waives any and all statutory and/or common law landlord lien which now exists 

or hereafter arises in connection with this Lease.  

13.1.5 Suits by Landlord . Actions or suits for the recovery of amounts and damages payable under this Lease may be brought by 

Landlord from time to time, at Landlord’s election, and Landlord shall not be required to await the date upon which the Lease Term would 
have expired to bring any such action or suit.  

13.1.6 Recovery of Landlord Enforcement Costs . All reasonable costs and expenses incurred by Landlord in connection with 
collecting any amounts and damages owing by Tenant pursuant to the provisions of this Lease or to enforce any provision of this Lease, 
including reasonable attorneys’ fees, whether or not any action is commenced by Landlord, shall be paid by Tenant to Landlord upon demand.  

13.1.7 Administrative Late Charge . Other remedies for nonpayment of rent notwithstanding, if the Monthly Rental, Monthly 

Deposit or Additional Rent is not received by Landlord on or before the tenth day of the month for which such rental or deposit is due, or if any 
other payment due Landlord by Tenant is not received by Landlord on or before the last day of the month next following the month in which 
Tenant was invoiced, a one-time administrative late charge of five percent (5%) of such past due amount shall become immediately due and 
payable in addition to such amounts owed under this Lease to help defray the additional cost to Landlord for processing such late payments.  

13.1.8 Interest on Past-Due Payments and Advances . Tenant covenants and agrees to pay to Landlord interest at the rate of fifteen 

percent (15%) per annum, compounded on a monthly basis, on the amount of any Basic Rent, Monthly Deposit, Additional Rent or other 
charges not paid when due, from the date due and payable, and on the amount of any payment made by Landlord required to have been made 
by Tenant under this Lease and on the amount of any costs and expenses, including reasonable attorneys’ fees, paid by Landlord in connection 
with the taking of any action to cure any Default by Tenant, from the date of making any such payment or the advancement of such costs and 
expenses by Landlord.  

13.1.9 Landlord’s Bankruptcy Remedies . Nothing contained in this Lease shall limit or prejudice the right of Landlord to prove and 

obtain as liquidated damages in any bankruptcy, insolvency, receivership, reorganization or dissolution proceeding, an amount equal to the 
maximum allowable by any statute or rule of law governing such proceeding in effect at the time when such damages are to be proved, whether 
or not such amount be greater, equal or less than the amounts recoverable, either as damages or rent, under this Lease.  

13.2 Remedies Cumulative . Exercise of any of the remedies of Landlord under this Lease shall not prevent the concurrent or subsequent 

exercise of any other remedy provided for in this Lease or otherwise available to Landlord at law or in equity.  

ARTICLE 14  
SURRENDER AND HOLDING OVER  

14.1 Surrender upon Lease . Upon the expiration or earlier termination of this Lease, or on the date specified in any demand for 

possession by Landlord after any Default by Tenant, Tenant covenants and agrees to surrender possession of the Demised Premises to Landlord 
broom clean, with all lighting, doors,  

24  

   
and electrical and mechanical systems (including, without limitation, all HVAC facilities) in good working order and condition, all walls in 
clean condition and holes or punctures in the walls repaired, and otherwise in the same condition as specified in Exhibit I attached hereto, 
casualty, condemnation and ordinary wear and tear excepted (such exceptions shall not limit Tenant’s obligation under Section 14.3.  

14.2 Holding Over . If Tenant shall hold over after the expiration of the Lease Term, without written agreement providing otherwise, 
Tenant shall be deemed to be a Tenant at sufferance, at a Monthly Rental (except as provided in the last sentence of this Section 14.2), payable 
in advance, equal to one hundred fifty percent (150%) of the Monthly Rental, and Tenant shall be bound by all of the other terms, covenants 
and agreements of this Lease, including without limitation the obligation to pay Additional Rent. Nothing contained herein shall be construed 
to give Tenant the right to hold over at any time, and Landlord may exercise any and all remedies at law or in equity to recover possession of 
the Demised Premises, as well as any damages incurred by Landlord, due to Tenant’s failure to vacate the Demised Premises and deliver 
possession to Landlord as herein provided. If Tenant has not delivered the certificate of substantial completion and certificate of occupancy for 
Tenant’s Restoration Obligations as required by Section 14.3 below on or before the expiration of the Lease Term, Tenant shall be deemed to 
be a Tenant at sufferance, at a monthly rental, payable in advance, equal to the Monthly Rental, and Tenant shall be bound by all of the other 
terms, covenants and agreements of this Lease, including without limitation the obligation to pay Additional Rent.  

14.3 Restoration Obligations . Upon the expiration or earlier termination of this Lease, or upon the date specified in any written demand 
for possession by Landlord after any Default by Tenant which date may not be less than six (6) months from the date of such notice), Tenant 
shall have completed all work associated with the removal of Tenant’s Equipment, fixtures, systems, and tenant improvements, whether by 
Tenant or Baxter, and restoration and reconstruction of the Demised Premises to the conditions described in Exhibit I attached hereto (referred 
to herein as Tenant’s “Restoration Obligations”). All such work shall be completed in a good and workmanlike manner by Quinlan 
Construction or other general contractor reasonably acceptable to Landlord. Repairing damage from casualty, the repair of which is subject to 
Articel 10 hereof, is not part of the Restoration Obligations. Tenant is responsible for all permits, fees, and costs associated with the work and 
must deliver to Landlord: (i) a certificate of substantial completion signed by the general contractor performing the work, and (ii), if required 
by the City, a certificate of occupancy from the City of Boulder for the Demised Premises following substantial completion of the restoration 
work. Prior to the commencement of the Tenant’s Restoration Obligations described and defined by this Section 14.3 and Exhibit I , Tenant 
must give Landlord written notice that Tenant intends to commence such work. Landlord may, at its sole option, reduce or eliminate any of 
Tenant’s Restoration Obligations by written notice to Tenant within fifteen (15) days from Tenant’s notice to Landlord, or, if earlier, with any 
written demand by Landlord for possession; provided, however, Landlord may not alter Tenant’s Restoration Obligations in any manner that 
increases Tenant’s cost of performance or prevents Tenant from recovering Tenant’s Equipment. If Tenant has not delivered the certificate of 
substantial completion and certificate of occupancy by the applicable deadline set forth in this Section 14.3, then Tenant will be deemed in 
default of this Section 14.3.  

ARTICLE 15  
MISCELLANEOUS  

15.1 No Implied Waiver . No failure by Landlord to insist upon the strict performance of any term, covenant or agreement contained in 

this Lease, no failure by Landlord to exercise any right or remedy under this Lease, and no acceptance of full or partial payment during the 
continuance of any Default by Tenant, shall constitute a waiver of any such term, covenant or agreement, or a waiver of any such right or  

25  

   
remedy, or a waiver of any such Default by Tenant. Similarly, no failure by Tenant to insist upon the strict performance of any term, covenant 
or agreement contained in this Lease and no failure by Tenant to exercise any right or remedy under this Lease shall constitute a waiver of any 
such term, covenant or agreement or a waiver of any such right or remedy, or a waiver of any default by Landlord.  

15.2 Survival of Provisions . Notwithstanding any termination of this Lease, the same shall continue in force and effect as to any 

provisions hereof that require observance or performance by Landlord or Tenant subsequent to termination.  

15.3 Covenants Independent . This Lease shall be construed as if the Covenants herein between Landlord and Tenant are independent, 

and not dependent, and Tenant shall not be entitled to any offset against Landlord if Landlord fails to perform its obligations under this Lease.  

15.4 Covenants as Conditions . Each provision of this Lease performable by Tenant shall be deemed both a covenant and a condition.  

15.5 Tenant’s Remedies . Tenant may bring a separate action against Landlord for any claim Tenant may have against Landlord under 
this Lease, provided that Tenant shall first give written notice thereof to Landlord and shall afford Landlord a reasonable opportunity to cure 
any such default. In addition, Tenant shall send notice of such default by certified or registered mail, postage prepaid, to the holder of any 
mortgage or deed of trust covering the Demised Premises, the Property or any portion thereof of whose address Tenant has been notified in 
writing, and shall afford such holder a reasonable opportunity to cure any default on Landlord’s behalf. In no event will Landlord be 
responsible for any incidental, consequential or special damages incurred by Tenant, including, but not limited to, loss of profits or interruption 
of business as a result of any default by Landlord hereunder. In no event will Tenant be responsible for any incidental, consequential or special 
damages incurred by Landlord, including, but not limited to, loss of profits or interruption of business as a result of any default by Tenant 
hereunder, except as may be specifically provided under the terms of this Lease

the respective parties hereto. The terms, covenants, agreements and conditions in this Lease shall be construed as covenants running with the

recording, containing the names of the parties, a description of the Demised Premises and the Lease Term prepared and recorded at Landlord’s 
cost.

transmission, (iii) the date of confirmed delivery when delivery is by delivery service; or (iv) or three (3) business days after mailing, if sent by 
registered or certified United States mail, postage prepaid, addressed to the party to receive the notice all at the address or facsimile number set 
forth for such party in the first paragraph of this Lease or at such other address as either party may notify the other of in writing. Any notice by 
Tenant to Landlord shall not be effective until a copy thereof shall have been received by or transmitted in the same manner to Landlord’s 
counsel at the address set forth in the Summary of Basic Lease Terms or such other address as Landlord may from time to time notify Tenant in 
writing.  

26  

   
15.9 Force Majeure . In the event that Landlord shall be delayed or hindered in, or prevented from, the performance of any act required 

hereunder by reason of strikes, lock-outs, labor troubles, inability to procure materials, failure of power or unavailability of utilities, riots, 
insurrection, war or other reason of like nature not the fault of Landlord, or not within its reasonable control, the performance of such acts shall 
be excused for the period of delay, and the period for the performance of any such act shall be extended for a period equivalent to the period of 
such delay (including extension of both the commencement and expiration dates of this Lease); provided, however, that if Tenant is not in any 
way responsible for the delay and does not have use or occupancy of the Demised Premises during the period of delay, the rent and other 
charges payable hereunder shall be abated for such period of delay. In the event that Tenant shall be delayed or hindered in, or prevented from, 
the performance of any act required hereunder by reason of strikes, lock-outs, labor troubles, inability to procure materials, failure of power or 
unavailability of utilities, riots, insurrection, war or other reason of like nature not the fault of Tenant, or not within its reasonable control, the 
performance of such acts shall be excused for the period of delay, and the period for the performance of any such act shall be extended for a 
period equivalent to the period of such delay (including extension of the expiration date of this Lease); provided, however, that if the delay 
results in extension of the Lease Term, Tenant will continue to pay the rent and other charges payable hereunder for such period of extension.  

15.10 Time of the Essence . Time is of the essence under this Lease, and all provisions herein relating thereto shall be strictly construed.  

15.11 Captions for Convenience . The headings and captions hereof are for convenience only and shall not be considered in interpreting 

the provisions hereof.  

15.12 Severability . If any provision of this Lease shall be held invalid or unenforceable, the remainder of this Lease shall not be affected

and waive any right to alter or change venue, including removal.

complete expression of the parties’ agreement with respect to the Demised Premises and Tenant’s occupancy thereof. Each party agrees that it 
has not relied upon or regarded as binding any prior agreements, negotiations, representations, or understandings, whether oral or written,

principal and agent or of partnership, or of joint venture by the parties hereto, it being understood and agreed that no provision contained in this 
Lease nor any acts of the parties hereto shall be deemed to create any relationship other than the relationship of Landlord and Tenant.  

15.18 Authority of Tenant . Each individual executing this Lease on behalf of a party represents and warrants that he is duly authorized to
