ITEM 2 OUR BUSINESS

2.1 OVERVIEW

We are a specialty pharmaceutical company that discovers and develops innovative therapeutic peptide products with an emphasis on growth-hormone releasing factor, or GRF, peptides. Our strategy is to leverage our expertise in the field of metabolism and GRF peptides to address serious health disorders while remaining actively involved in the commercialization of our future products. Our first product, EGRIFTA^® (tesamorelin for injection), was approved by the United States Food and Drug Administration, or FDA, in November 2010. EGRIFTA^® is currently the only approved therapy for the reduction of excess abdominal fat in HIV-infected patients with lipodystrophy.

We estimate that excess abdominal fat in HIV-infected patients affects approximately 29% of HIV-infected patients treated with antiretroviral therapies and approximately 12% of untreated patients. In HIV-infected patients, lipodystrophy may be caused by the viral infection itself, the use of antiretroviral therapy, or both. Lipodystrophy is characterized by abnormalities in the production and storage of fat, which lead to excess abdominal fat, or lipohypertrophy, and the loss of fat tissue, or lipoatrophy, generally occurring in the limbs and facial area.

Excess abdominal fat in HIV-infected patients is associated with significant health risks beyond the mortality risk of the HIV infection itself. These health risks include metabolic disturbances such as hyperlipidemia, an increase in the amount of fat in the blood (such as triglycerides and cholesterol), and hyperglycemia, an increase in the amount of sugar in the blood, characterized by insulin resistance, both of which lead to increased risks of cardiovascular disease and diabetes. While there is evidence that suggests that lipoatrophy may be reduced with certain newer HIV therapies, we are not aware of any evidence showing that any currently-marketed HIV therapy reduces lipohypertrophy or the incidence of lipohypertrophy.

EGRIFTA^® is currently marketed exclusively in the United States by EMD Serono Inc., or EMD Serono, an affiliate of Merck KGaA, Darmstadt, Germany, pursuant to a collaboration and licensing agreement. We have also recently entered into distribution and licensing agreements for EGRIFTA^® with Sanofi Winthrop Industries S.A., or Sanofi, granting Sanofi the exclusive commercialization rights in Latin America, Africa and the Middle East and with Ferrer Internacional S.A., or Ferrer, granting Ferrer the exclusive commercialization rights in Europe, Russia, South Korea, Taiwan, Thailand and certain central Asian countries. For a description of these agreements, see Item 2.5. Using data compiled by the United States Center for Disease Control, or CDC, and the World Health Organization and UNAIDS, or WHO/UNAIDS, we estimate that in 2012 there will be approximately 190,000 HIV-infected patients treated with antiretroviral therapies with lipohypertrophy in the United States, 170,000 in Europe, and 180,000 in Latin America, or 540,000 patients in total. We also estimate that in 2012, there will be an additional 47,000 HIV-infected untreated patients with lipohypertrophy in the United States, 42,000 in Europe, and 28,000 in Latin America, or an additional 117,000 patients in total.

In January 2011, EMD Serono launched EGRIFTA^® in the United States. EMD Serono is executing a launch program that consists of medical education, advertising, marketing and promotion through their experienced sales force, and supporting market access through co-pay programs, reimbursement education and support for payors. We believe EGRIFTA^® will achieve a high degree of physician and payor acceptance, driven by our product’s safety and efficacy, the lack of approved alternative therapies for these patients and the prominent medical and social need to treat HIV/AIDS patients.

- 7 -

EGRIFTA^® is the trade name used for our first marketed product using our most advanced compound, tesamorelin. Tesamorelin is a GRF analogue that stimulates the synthesis and pulsatile release of endogenous growth hormone. Tesamorelin was synthesized using our internally-developed peptide stabilization method. This method increases a protein’s resistance to enzymatic degradation, which prolongs its duration of action and enhances its effectiveness in clinical use. We believe this compound and future GRF analogues that we are developing can be used in a number of additional high-value indications. Clinical data have shown tesamorelin to have both lipolytic (fat-burning) and anabolic (muscle-building) properties. Our initial development of EGRIFTA^® focused on the lipolytic properties of the compound.

Tesamorelin’s anabolic properties have led us to pursue its development for muscle wasting in COPD patients as our second indication. COPD is characterized by progressive airflow obstruction due to chronic bronchitis or emphysema leading in certain cases to muscle wasting, a decrease of muscle mass and deterioration in functionality. We have completed a Phase 2 trial which demonstrated a statistically significant increase in lean body mass. Based upon these trial results, we intend to randomize our first patient in a new Phase 2 clinical study in the second half of 2011. Based on available market data, we estimate that in 2009, the number of diagnosed COPD patients with muscle wasting was approximately 3.1 million in the United States, France, Germany, Italy, United Kingdom, Spain and Japan.

To solidify our leadership position in the field of GRF therapeutics, we have embarked on a program to discover new generations of GRF analogues. We believe that GRF compounds have the potential to improve patient outcome in many high-value indications, such as wasting in chronic heart failure and renal failure, as well as growth deficiency with abdominal obesity. We also believe that we can improve the route of administration of GRF peptides to make them quicker and easier to use for patients. Our early-stage pipeline also includes compounds for the treatment of Acute Kidney Injury, or AKI, and certain cancers.

2.2 RECENT DEVELOPMENTS

Since the end of our most recently completed financial year, we have been engaged in the following activities:

	•		COPD indication for EGRIFTA^®. On February 22, 2011, we announced a new clinical program in muscle wasting in COPD using tesamorelin. Tesamorelin’s anabolic properties have led us to pursue the development of tesamorelin for muscle wasting in COPD patients for its second indication. The program will be conducted in stable ambulatory COPD patients with muscle wasting in the Global Initiative for Chronic Obstructive Lung Disease, or GOLD, stage II and III severity experiencing decreased functionality in daily activities.

	•		Execution of distribution and licensing agreement for EGRIFTA^®for European market. On February 3, 2011, we announced the execution, through Theratechnologies Europe Inc., of a distribution and licensing agreement with Ferrer granting it the exclusive commercialization rights of tesamorelin in Europe, Russia, South Korea, Taiwan, Thailand and certain central Asian countries for the reduction of excess abdominal fat in HIV-infected patients with lipodystrophy. For a description of this agreement, see Item 2.5.

	•		Execution of distribution and licensing agreement for EGRIFTA^® for the Latin American, African and Middle Eastern Markets. On December 6, 2010, we announced the execution, through Theratechnologies Intercontinental Inc., of a distribution and licensing agreement with sanofi-aventis S.A., granting one of its subsidiaries, Sanofi Winthrop Industries, the exclusive distribution rights to EGRIFTA^® in Latin America, Africa and the Middle East for the reduction

On December 15, 2008, we announced the 52-week results of our confirmatory Phase 3 clinical trial, evaluating the long-term safety profile of tesamorelin in patients with HIV-associated lipodystrophy. The results reported from both the 26-week confirmatory clinical study and 52-week confirmatory clinical study were consistent with the efficacy and safety profile observed in the first Phase 3 clinical study. This announcement concluded the Phase 3 clinical studies for tesamorelin for the reduction of excess abdominal fat in HIV-infected patients with lipodystrophy.

	•		Execution of collaboration and licensing agreement with EMD Serono for tesamorelin in the United States. On October 29, 2008, we announced the execution of a collaboration and licensing agreement with EMD Serono for the exclusive commercialization rights to tesamorelin in the United States for the reduction of excess abdominal fat in HIV patients with lipodystrophy. For a description of this collaboration and licensing agreement, see Item 2.5.

	•		26-week confirmatory Phase 3 clinical trial results for tesamorelin. On June 18, 2008, we announced our 26-week results of our confirmatory Phase 3 clinical trial, evaluating the efficacy of tesamorelin in patients with HIV-associated lipodystrophy. The study was powered to detect an 8% reduction in visceral adipose tissue versus placebo. The study met its primary endpoint as well as important secondary endpoints confirming the positive results obtained in our initial Phase 3 study.

	•		Execution of strategic agreement with Dr. Grinspoon. On May 15, 2008, we announced our entering into an agreement with both the MGH and Dr. Grinspoon to explore the use of tesamorelin in relative growth hormone deficient abdominally obese, or GHDAO, subjects. MGH, under the direction of Dr. Grinspoon, is the sponsor and is conducting a Phase 2 clinical trial with tesamorelin in subjects who have excess visceral adipose tissue, or VAT, with a moderate growth hormone deficiency and who are abdominally obese. We accepted to provide tesamorelin for this study and the MGH will retain the rights to the results generated by this study, and we obtained an exclusive worldwide license to commercialize any results. Dr. Grinspoon completed subject enrolment in December 2010.

	•		Initiation of process to explore strategic options. On January 29, 2008, we announced that our board of directors initiated a process to explore strategic options available to the Company to further enhance shareholder value.

	•		US patent for tesamorelin issued. On January 8, 2008, we announced that the United States Patent and Trademark Office, or USPTO, issued Patent Number 7,316,997 entitled “GH Secretagogues and Uses Thereof” to Theratechnologies.

The granting of this patent extended the patent term protection of tesamorelin in HIV-associated lipodystrophy for eight additional years, until 2023.

	•		Phase 3 first clinical trial results for tesamorelin. On December 5, 2007, we announced that the results of our first Phase 3 clinical trial using tesamorelin were published in the December 6, 2007 New England Journal of Medicine (www.nejm.org). The study, entitled “Metabolic Effects of a Growth Hormone-Releasing Factor in Patients with HIV”, outlines, in detail, the 26-week data of the trial. Top-line results of this Phase 3 trial were initially disclosed in December 2006.

	•		Preclinical work for AKI. We conducted some preclinical work on a molecule known as THG213.29 with the intent of pursuing a clinical program in AKI. Through our research and development, we discovered a new bifunctional peptide that appears to have favourable properties in the treatment of AKI in animal models of AKI. During our 2008 fiscal year, we

- 10 -

replaced THG213.29 with the new bifunctional peptide TH0673 in the event we decide to develop a clinical program for AKI.

2.4 OUR STRATEGY

Our goal is to leverage our expertise in the field of metabolism and GRF peptides to become a leading specialty pharmaceutical company with the necessary infrastructure to take innovative therapeutic products from research and development to full commercialization in worldwide markets. Key elements of this strategy include:

Maximize the global commercial potential of EGRIFTA^®

In order to maximize the commercial potential of EGRIFTA^® we have entered into licensing agreements with EMD Serono, Sanofi and Ferrer for different territories around the world. We intend to continue to support our commercial partners to ensure the successful commercialization of EGRIFTA^® in their respective territories. This will include regulatory support, manufacture and supply of EGRIFTA^®, and potential co-promotion.

We have developed a new presentation of EGRIFTA^® which is quicker and easier to use than its current presentation. We are also developing a new and more concentrated formulation of tesamorelin. Compared to our current formulation, this new formulation requires a smaller volume of injection and is expected to be stable at room temperature. In addition, this new formulation could potentially be used with a new delivery device such as a pen, to facilitate patient self-administration. We expect the new presentation and the new formulation will have a positive impact on our manufacturing capacity and will significantly reduce our unit costs.

Develop tesamorelin for muscle wasting in COPD

We will be conducting a new clinical program in muscle wasting in COPD. We have demonstrated in a first Phase 2 clinical trial that tesamorelin has increased muscle mass in COPD patients. We believe tesamorelin could improve patients’ functionality in daily activities and address a significant unmet need in a large and potentially lucrative market.

Solidify our position as a leader in the field of novel GRF products

We will leverage our expertise in peptide discovery, drug development and regulatory affairs to continue our development of new peptides, primarily GRF peptides, in order to expand our portfolio of product candidates and solidify our position as a leader in this field.

Be actively involved in the commercialization of our products

We intend to retain commercial rights to our future products for indications and territories where we believe we can effectively market them. We may also co-promote EGRIFTA^® in certain territories and tesamorelin in other indications.

Pursue external growth opportunities

In addition to developing products internally, we will opportunistically pursue in-licensing arrangements or acquisitions of complementary businesses, compounds or products. We will also identify and evaluate commercial growth opportunities that may include collaborations with drug delivery companies.

2.5 OUR PRODUCT AND PRODUCT CANDIDATES

The following table provides an overview of our product and product candidates and their current stages of development:

EGRIFTA^® — Our Lead Product

EGRIFTA^® induces the release of growth hormone which causes a reduction in excess abdominal fat (lipohypertrophy) in HIV-infected patients without reducing or interfering with subcutaneous fat, and, as such, has no clinically significant effect on undesired loss of subcutaneous fat (lipoatrophy).

EGRIFTA^® is currently available in the United States as a once-daily two unit dose (two vials, each containing 1 mg of tesamorelin) of sterilized lyophilized powder to be reconstituted with sterile water for injection. To administer EGRIFTA^®, 1 ml is retrieved from each vial into one syringe to prepare a single 2 ml patient self-administered subcutaneous injection. EGRIFTA^® is injected under the skin into the abdomen once a day.

For the purposes of FDA approval, EGRIFTA^® was evaluated in two clinical trials involving 816 HIV-infected adult men and women with lipodystrophy and excess abdominal fat. In both studies, patients treated daily with EGRIFTA^® experienced greater reductions in abdominal fat as measured by CT scan and greater improvements in belly appearance distress, compared with patients receiving another injectable solution (placebo). Once the treatment was terminated, the patients’ condition reversed to its status prior to the beginning of the treatment. The most commonly reported adverse effects in the studies included reactions due to the release of endogenous hormone, such as joint pain (arthralgia), pain in the extremities, swelling in the lower limbs and muscle pain (myalgia), injection site reactions such as skin redness (erythema), itching (pruritis) and pain and clinically manageable changes in blood sugar control. Our clinical trials did not seek to measure any potential cardiovascular benefits of EGRIFTA^® on cardiovascular events.

In connection with its approval, the FDA has required the following three post-approval commitments:

•

to develop a single vial presentation of the existing formulation of EGRIFTA^®. We have developed a new presentation of EGRIFTA^® which is quicker and easier to use than its current presentation. In the new presentation, EGRIFTA^® will be available as a single unit dose (one vial containing 2 mg of tesamorelin) of sterile, lyophilized powder to be reconstituted with sterile water for injection. The FDA requires that this new presentation be available by

- 12 -

November 2013 and we expect it to be commercially available before that date. The development of the new presentation is complete and the dossier is ready for regulatory submission.

	•		to conduct a long-term observational safety study using EGRIFTA^®. The purpose of the long-term observational study required by the FDA is to evaluate the safety of long-term administration of EGRIFTA^®.

	•		to conduct a Phase 4 clinical trial using EGRIFTA^®. The primary purpose of the Phase 4 clinical trial is to assess whether EGRIFTA^® increases the incidence or progression of diabetic retinopathy in diabetic HIV-infected patients with lipodystrophy and excess abdominal fat.

The FDA requires that the proposed protocols for the long-term observational safety study and Phase 4 clinical trial be submitted by the second quarter of 2011. Under the terms of our collaboration and licensing agreement, EMD Serono is responsible for finalizing and obtaining approval of such protocols. We will continue to support EMD Serono in developing and finalizing such protocols.

Lipodystrophy

Lipodystrophy is characterized by abnormalities in the production and storage of fat. It has two components: lipohypertrophy, abnormal and excessive fat accumulation, and lipoatrophy, the noticeable, localized loss of fat tissue under the skin. In patients with lipohypertrophy, fat accumulation occurs mostly around the waist and may also occur in other regions, including breast tissue and in dorsocervical tissues in the neck, resulting in a “buffalo hump”. Excess fat also appears as lipomas, or benign tumors composed of fat cells. In patients with lipoatrophy, the loss of fat tissue generally occurs in the limbs and facial area.

In HIV-infected patients, lipodystrophy may be caused by the viral infection itself, the use of antiretroviral therapy, or both. While there is evidence that suggests that lipoatrophy may be reduced with certain newer HIV therapies, we are not aware of any evidence showing that any currently-marketed HIV therapy reduces lipohypertrophy or the incidence of lipohypertrophy. Recent data suggest that different pathophysiological mechanisms are involved in the development of lipohypertrophy and lipoatrophy. The most common statistically significant independent risk factors identified for lipohypertrophy are duration of antiretroviral therapy, markers of disease severity and protease inhibitor use. Other factors include age, genetics, and gender.

Market Opportunity

Based on our analysis of 20 independent medical studies published from 2000 to 2004, we estimate that excess abdominal fat in HIV-infected patients affects approximately 29% of HIV-infected patients treated with antiretroviral therapies. According to a separate 2003 independent medical study, we estimate that an additional 12% of untreated HIV-infected patients are also affected by excess abdominal fat.

Based on the above-mentioned data, we have identified the following potential markets for EGRIFTA^®.

- 13 -

	•		United States. The United States market represents the largest commercial opportunity for EGRIFTA^®. We estimate the prevalence of HIV/AIDS in the United States will rise to 1.3 million people in 2012. Of this amount, approximately 650,000 people will be treated for HIV/AIDS and, of those patients treated, approximately 190,000 will suffer from excess abdominal fat. In addition, approximately 47,000 untreated patients will suffer from excess abdominal fat.

	•		Europe. We estimate the prevalence of HIV/AIDS in Europe will rise to 1.4 million people in 2012. Of this amount, approximately 590,000 people will be treated for HIV/AIDS and, of those patients treated, approximately 170,000 will suffer from excess abdominal fat. In addition, approximately 42,000 untreated patients will suffer from excess abdominal fat.

	•		Latin America. We estimate the prevalence of HIV/AIDS in Latin America will rise to 2.2 million people in 2012. Of this amount, approximately 630,000 people will be treated for HIV/AIDS and, of those patients treated, approximately 180,000 will suffer from excess abdominal fat. This number is proportionately lower than the other territories due to a lower percentage of diagnosed and treated patients. With approximately 60,000 treated patients who will suffer from excess abdominal fat, Brazil offers the largest market in Latin America for EGRIFTA^®. In addition, approximately 28,000 untreated patients will suffer from excess abdominal fat.

We estimate that the total number of patients diagnosed with and treated for HIV/AIDS who will suffer from excess abdominal fat in our primary target markets will be 540,000 in 2012. We estimate that an additional 117,000 untreated patients may develop lipohypertrophy in such markets.

The foregoing information is based on historical data from the CDC for the United States, and WHO/UNAIDS for Europe and Latin America. We used the historical growth rates derived from that data to estimate the prevalence of HIV/AIDS in 2012.

EGRIFTA^® Commercialization Activities

We are working closely with EMD Serono to support the commercialization of EGRIFTA^®. We are also working closely with Sanofi and Ferrer to obtain regulatory approval for and the subsequent commercialization of EGRIFTA^®. Each of our commercial partners were chosen due to their commercial and regulatory capabilities in their respective territories.

This agreement extends until the later of the expiration of the last valid claim based on a patent right (including patent applications) controlled by us covering a product licensed under the agreement or ten years from the date of the first commercial sale of EGRIFTA^® for each country covered by the agreement.

Unpartnered Territories

We have retained full commercial rights for EGRIFTA^® in certain territories, including Canada. In territories where we do not currently have commercial partners, we may commercialize EGRIFTA^® directly or in collaboration with commercial partners.

Tesamorelin — Our Lead Compound

Tesamorelin is a stabilized 44 amino acid human GRF analogue, which was synthesized in our laboratories in 1995 using our long-acting peptide method. Although natural peptides have significant therapeutic potential, they are subject to enzymatic degradation which severely limits their effectiveness in clinical use. Our long-acting peptide method is a peptide stabilization process which increases the target protein’s resistance to enzymatic degradation, while maintaining its natural specificity. This usually results in a more stable and efficient compound, which can thus prolong its duration of action. Tesamorelin induces growth hormone secretion in a natural and pulsatile way. The clinical results obtained to date using tesamorelin suggest a therapeutic potential in both anabolic and lipolytic indications. EGRIFTA^® has demonstrated the ability to significantly reduce visceral adipose tissue, increase muscle mass and reduce waist circumference.

Mechanism of action

In vitro, tesamorelin binds and stimulates human GRF receptors with similar potency as the endogenous GRF. GRF is a hypothalamic peptide that acts on the pituitary somatotroph cells to stimulate the synthesis and pulsatile release of endogenous growth hormone, which is both anabolic and lipolytic. Growth hormone exerts its effects by interacting with specific receptors on a variety of target cells, including chondrocytes, osteoblasts, myocytes, hepatocytes, and adipocytes, resulting in a host of pharmacodynamic effects. Some, but not all these effects, are primarily mediated by insulin-like growth factor one, IGF-1, produced in the liver and in peripheral tissues.

The effects of recombinant human growth hormone, or rhGH, and tesamorelin have been the subject of several clinical trials in the area of HIV-associated lipodystrophy. Based on these clinical trials, the safety profiles of rhGH and tesamorelin appear to be very different. The natural synthesis of growth hormone is regulated by a feedback mechanism preventing its overproduction. Tesamorelin induces optimal activity of the somatotrope function and retains the natural rhythm (pulsatility) of the physiological secretion of growth hormone without interfering with the feedback mechanism mentioned above. With the exogenous administration of rhGH, the feedback mechanisms are short-circuited, which gives rise to higher levels of growth hormone. The side effects associated with rhGH include nerve, muscle or joint pain, swelling due to fluid retention (edema), carpal tunnel syndrome, numbness and tingling of skin and increased risk of diabetes. These side effects are particularly frequent among older people. In addition, rhGH can cause hyperglycemia which makes it contraindicated for patients with diabetes or pre-diabetic conditions.

Muscle Wasting in COPD — New Indication for Tesamorelin

We have selected COPD as our second clinical program with tesamorelin. We chose to consider muscle wasting in COPD patients with decreased functioning in daily activities for a clinical program based on the anabolic properties of tesamorelin. The goal of the program is to show an improvement in functionality in daily activities in COPD patients with loss of muscle mass.

We completed a three-month Phase 2 clinical study involving 109 stable ambulatory COPD patients. Patients were randomized to receive either 1 mg or 2 mg doses of tesamorelin, or a placebo each day. Patients treated using 1 mg or 2 mg doses of tesamorelin experienced a statistically significant increase in lean body mass compared with patients receiving a placebo. In addition to the increase in lean body mass, such patients experienced improvements in three functional measures associated with tesamorelin, particularly for the 2 mg group. The three functional measures were:

	•		Respiratory symptoms, as assessed by St. George’s Respiratory Questionnaire;

	•		Leg discomfort, as assessed by the Borg Scale following an exercise endurance test; and

	•		Breathing discomfort, as assessed by the Borg Scale following an exercise endurance test.

COPD

COPD is characterized by progressive airflow obstruction due to chronic bronchitis or emphysema, two commonly co-existing lung diseases. COPD results in a limitation of the flow of air to and from the lungs resulting in a shortness of breath. In contrast to asthma, the limitation of airflow is not easily reversible and usually gets progressively worse over time.

Many COPD patients are affected by a systemic manifestation which may lead to muscle wasting. Muscle wasting (cachexia or involuntary weight loss), a decrease or thinning of the muscle mass, is associated with several abnormalities, including impaired exercise capacity and functioning and decreased muscle strength. Muscle wasting is an independent predictor of a COPD patient’s functional deterioration and mortality, and it is a common symptom in patients with moderate to severe COPD. The importance of improving not only muscle strength, but other functional parameters and quality of life is well recognized in order to improve the well being of patients with COPD and decreased functionality. We are not aware of any treatment for muscle wasting in COPD approved by any regulatory authorities.

Market opportunity

According to independent research, 26 million adults aged 40 or over were diagnosed with COPD in the United States, France, Germany, Italy, the United Kingdom, Spain and Japan in 2009. The prevalence of COPD increases with age and is much higher in adult males. The diagnosed population is expected to increase at a compound annual growth rate of 2.5%.

Treatment varies across countries and region, however 17.9 million patients were receiving treatment for COPD management in 2009 in the United States, France, Germany, Italy, the United Kingdom, Spain and Japan. COPD can be classified using four levels of severity, from mild to very severe (stages I to IV) using the GOLD classification. Our program will focus primarily on COPD patients in GOLD stage II and III. Based on available market data, we estimate that in 2009, the number of diagnosed COPD patients in GOLD stage II and III suffering from a muscle wasting condition, with a body mass index of under 25, was approximately 3.1 million in those markets.

- 17 -

Clinical development plan

Tesamorelin’s anabolic properties have led us to pursue its development for muscle wasting in COPD patients as our second indication. This clinical development program will be conducted in stable ambulatory COPD patients, GOLD stage II and III, with muscle wasting experiencing decreased functionality in daily activities. It will include three studies:

	•		One Phase 2 study: This study will be a randomized, placebo controlled study in approximately 200 COPD patients with muscle wasting. Patients will be randomized to receive either one of two different dosages of tesamorelin or placebo each day for six months. We intend to randomize our first patient in this Phase 2 clinical study in the second half of 2011. The Phase 2 study will evaluate the safety and efficacy of using tesamorelin in COPD patients, GOLD stage II and III, with muscle wasting. The primary endpoint will be an increase in lean body mass. Other efficacy endpoints will be measured, such as a six minute walking distance test, exercise endurance time, and quality of life (daily activities). Safety assessments will include monitoring of adverse events and laboratory evaluations.

	•		Two Phase 3 studies: If the Phase 2 study is successful, we anticipate there will be two 12-month Phase 3 studies (one pivotal and one confirmatory) to be conducted in parallel. We expect a total of approximately 1,200 patients will be included in this program.

We currently believe that the clinical trials will last approximately four years and that the program will cost between approximately $55 and $65 million. A significant portion of the costs will be borne by our commercial partners if they elect to exercise their option to commercialize under their respective agreements.

Other Product Candidates

Novel Growth Hormone-Releasing Factor Analogues

We are working on several novel analogues of GRF that have improved chemical stability compared to tesamorelin. To date, we have synthesized over 80 different compounds. We believe that GRF compounds have the potential to improve patient outcome in many high-value indications. We also believe we can improve the route of administration of GRF peptides to make them quicker and easier to use for patients.

Compounds for Acute Kidney Injury

AKI is the acute deterioration of kidney function leading to increased urea waste products and electrolyte imbalance in blood. AKI is common among hospitalized patients and complicates the management of patients in intensive care units. According to a 2008 medical publication, AKI affected 3% to 7% of patients admitted to hospital and approximately 25% to 30% of patients in the intensive care unit within days of major surgery. The incidence of AKI was approximately 600,000 to 900,000 patients in the United States per year. Despite hospitalization and renal replacement, the mortality rate is 50% to 60% for dialyzed patients. We believe that hemodialysis is the only approved treatment for post-surgical AKI.

We have identified AKI as a potential clinical program for internal development. We have developed novel peptides specifically tailored for the prevention or treatment of AKI. One of these peptides, TH0673, is a peptide that is currently in preclinical development. We have tested TH0673 in animal models of AKI and have found that it increases creatinine clearance, improves excretion of nitrogenous waste compounds and limits kidney damage. We expect to have additional preclinical results in AKI in the first half of 2011.

Other Discovery Activities — Melanotransferrin Peptides (Anti-cancer compounds)

In November 2010, we entered into a discovery and collaboration agreement with the UQAM, Gestion Valeo and Transfert Plus in connection with research led by Dr. Richard Béliveau seeking to discover short peptide mimics of melanotransferrin for the development of a new cancer treatment.

Melanotransferrin is related to the transferrin family of proteins and is expressed normally in melanocytes, but also in several cancer cells. Dr. Béliveau’s research has demonstrated that soluble melanotransferrin reduces cell migration, invasion and angiogenesis, which are hallmarks of tumorigenesis and metastasis. We have identified small peptides from the melanotransferrin protein which could replicate the functions of the full length protein. Currently, we are optimizing the peptides for better pharmaceutical properties so that the optimized peptides can be tested in animal models of cancer and tumor angiogenesis.

2.6 INTELLECTUAL PROPERTY

Our Current Patent Portfolio

Our current patent portfolio is comprised of patents and patent applications for the following compounds:

Tesamorelin

	•		In the United States, we own a patent covering the composition of matter (tesamorelin), which is scheduled to expire in 2015. We have applied for a patent term extension requesting an extension of five years to this patent term. If our request for patent term extension for the entire five year term is granted, the patent protection for tesamorelin in the United States would be extended until 2020. In addition, we own an issued United States patent relating to the use of tesamorelin in the treatment of HIV-associated lipodystrophy, which is scheduled to expire in 2023. Because tesamorelin qualifies as a new chemical entity, we benefit from data protection for a five year period for EGRIFTA^® ending November 2015. See “Regulatory Exclusivity”.

	•		In Europe, tesamorelin is covered by granted patents scheduled to expire in 2016. In the event of receipt of marketing approval from the European Medicines Agency, or EMA, we intend to apply for supplementary protection certificates, or SPCs, in certain countries which, if granted, could extend the patents covering tesamorelin in the countries where SPCs are approved until 2021. We have also filed two patent applications relating to the use of tesamorelin in the treatment of HIV-associated lipodystrophy where, if such patents were granted, they would be scheduled to expire in 2023 and 2025, respectively. As discussed below, the first time a new product is approved in Europe, the regulation provides for a 10 year exclusivity period. Assuming approval in 2012, we would benefit from protection until 2022. See “Regulatory Exclusivity”.

	•		We have obtained a patent covering the composition of matter (tesamorelin) in Brazil that expires in 2019.

	•		We have filed patent applications for the therapeutic indication of muscle wasting in COPD in several countries, including the United States, where, if such patents were granted, they would be scheduled to expire in 2024, with the exception of a recently-granted patent in the United States which benefits from a patent term adjustment extending its term to 2027.

- 19 -

	•		We have filed United States and international patent applications, for the new formulation of tesamorelin where, if such patents were granted, they would be scheduled to expire in 2028.

	•		We have filed United States and international Patent Cooperation Treaty applications, relating to combination therapies of tesamorelin with certain drugs indicated for the treatment of HIV which, if patents issued from these applications were granted, would be scheduled to expire in 2030.

			Novel GRF Peptides

	•		We have recently filed a United States provisional patent application relating to new GRF analogues. Patents claiming priority to this application may be pursued and, if such patents were granted, they would be scheduled to expire in 2032.

AKI

•

We have filed patent applications in several countries, including the United States, relating to our peptide TH0673 and related peptides, and their use in the treatment of AKI, where, if such patents were granted, they would be scheduled to expire in 2028.

Our Trademarks & Other Intellectual Property

EGRIFTA^® is the trademark used for tesamorelin for the reduction of excess abdominal fat in HIV-infected patients with lipodystrophy. Trademark registration in the United States necessitates a prior commercial use in the territory in order to be granted. We are in the process of filing the declaration of use to obtain trademark registration.

We have obtained registration for EGRIFTA^® in Europe, Japan, Australia, Norway, Switzerland, Mexico and Lebanon and have filed trademark applications for this trademark in other countries. The use of the trademark in each jurisdiction generally requires the approval of the regulatory authorities in such jurisdictions.

Other trademarks related to tesamorelin have been filed as part of our business strategy. We have also reserved certain domain names in order to support future activities.

Our Policy on Intellectual Property

Our intellectual property practice is to keep all information relating to proprietary compounds, inventions, improvements, trade secrets, know-how and continuing technological innovation confidential and, where practicable, file patent and trademark applications. In particular, as part of our intellectual property protection practice, we:

	•		perform surveillance of third party patents and patent applications in order to identify any third party patent or third party patent application which, if granted, could be infringed by our activities;

	•		where practicable, file patent applications for any new and patentable invention, development or improvement in the United States and in other countries;

	•		prosecute all pending patent applications in conformity with applicable patent laws and in a manner that efficiently covers our activities;

	•		file trademark applications in countries of interest for our trademarks;

- 20 -

	•		register domain names in countries of interest; and

	•		maintain our intellectual property rights by paying government fees as may be necessary to ensure such rights remain in force.

Regulatory Exclusivity

The regulatory regimes of the United States and Europe may provide market exclusivity for a pharmaceutical product. Data protection and patent term extension provide a patent holder with additional protection against third parties who may wish to commercialize a product similar to an approved product.

Data Protection

In the United States, the Drug Price Competition and Patent Term Restoration Act of 1984, also known as the Hatch-Waxman Act, awards, in certain circumstances, non-patent marketing exclusivities to pioneer drug manufacturers. The Hatch-Waxman Act provides five years of non-patent marketing exclusivity within the United States to an applicant who gains approval of a New Drug Application, or NDA, for a “new chemical entity,” a drug for which the FDA has not previously approved any other new drug with the same active moiety, which is the molecule or ion responsible for the action of the drug. This marketing exclusivity prevents the FDA from approving, in certain circumstances, any abbreviated new drug application for a generic drug or any 505(b)(2) NDA. See “Government Regulation — United States — FDA Process” below.

In Europe, when a product based on a new compound is approved, the EMA grants a 10 year exclusivity period beginning on the date of such approval. When the same compound is approved for a second indication within the first eight years of this 10 year period, the exclusivity period is extended by one year, providing a total exclusivity period of 11 years for the compound.

Patent Term Extension

In the United States, the Hatch-Waxman Act permits patent term extension for one patent per approved drug of up to five years for patent term lost during product development and the FDA regulatory review process. However, patent term extension cannot extend the remaining patent term beyond a total of 14 years from the product’s approval date. The patent term extension period is generally one-half the time between the effective date of an Investigational New Drug Application, or IND, and the submission date of an NDA plus the time between the submission date of an NDA and the NDA. We have applied for a patent term extension with respect to tesamorelin.

In the European Union, SPCs for medicinal products are governed by Regulation 469/2009 with effect from May 2009. An SPC has the effect of extending the term of a patent relating to protection of a particular medicinal product by compensating the patentee for some lost patent protection caused by the length of time taken to obtain marketing authorisation for the product in question. An SPC is a national right, available in member states of the European Union by application to the national patent office of each state for which a certificate is desired. The SPC must be based on a patent but since an SPC is only granted in respect of a very specific active ingredient in a product, it is generally of rather more limited scope than the patent on which it is based. Typically, the term of the SPC is equal to the period which has elapsed between filing of the patent application and grant of the first European Union marketing authorisation less five years. The term of the SPC may not, generally, exceed five years. However, some European Union legislation regarding pediatric medicines provides for a six-month extension of the basic SPC term in certain circumstances. The SPC takes effect on expiry of the basic patent. In each country for which SPC protection is sought, a separate SPC application must

- 21 -

be filed within six months of the grant of the first marketing authorisation in that country for the active ingredient(s) in question.

2.7 MANUFACTURING

We do not own or operate commercial scale manufacturing facilities for the production of our product or any of our product candidates, nor do we have plans to develop our own manufacturing operations in the foreseeable future. We currently depend on third-party contract manufacturers for all of our required raw materials, drug substance and finished product for clinical trials and commercial sale.

We are responsible for the manufacture and supply of tesamorelin to ensure the commercialization of EGRIFTA^® under our agreements with EMD Serono, Sanofi and Ferrer. As part of our agreement with EMD Serono, we are required to maintain certain levels of inventory. In order to fulfill these contractual obligations, we have negotiated and entered into various third-party supply agreements.

Bachem

We have an agreement with Bachem Inc., an American subsidiary of Swiss-based Bachem AG, providing for the manufacturing and supply of the active pharmaceutical ingredient of tesamorelin for clinical programs and EGRIFTA^® for commercial sale in the United States.

Draxis

We have an agreement with Draxis Pharma, a division of Draxis Specialty Pharmaceuticals, Inc., or Draxis, providing for the manufacture and supply of the finished form of tesamorelin for clinical programs and EGRIFTA^® for commercial sale. Under our agreement, Draxis must fill vials with tesamorelin, lyophilize it, label and package those vials and deliver them to locations in accordance with our instructions.

We have identified and initiated discussions with possible secondary suppliers of these products. We believe that there are alternate sources of supply for these products that will be able to satisfy our needs and will be able to receive FDA qualification. We expect our new presentation as well as our new formulation of tesamorelin will significantly increase our production capacity for EGRIFTA^® due to the smaller quantity of vials, shorter manufacturing process times and increased batch sizes.

We have also entered into the following manufacturing agreements as a result of our undertakings under the distribution and licensing agreement with EMD Serono wherein we agreed to supply the injection tool kits for EGRIFTA^® namely:

Becton Dickinson

On November 6, 2009, we entered into a supply agreement with Becton Dickinson Canada Inc., or Becton Dickinson. Under this agreement, Becton Dickinson is responsible for supplying us with syringes and hypodermic needles which are provided with EGRIFTA^® in the United States.

Hospira

On March 26, 2009, we entered into a development and supply agreement with Hospira Worldwide, Inc., or Hospira. Under this agreement, Hospira is responsible for manufacturing and supplying us with sterile water for injection, filled and finished in plastic vials, in connection with the sale of EGRIFTA^® in the United States.

- 22 -

ABAR

On January 5, 2010, we entered into a supply agreement with Gruppo Cartotecnico ABAR Litofarma S.R.L., or ABAR, an Italian company, in order to ensure the commercial supply of pharmaceutical mass market folding boxes for the sale of EGRIFTA^® in the United States.

2.8 COMPETITION

The pharmaceutical industry is characterized by intense competition and rapid innovation. Our potential competitors include large pharmaceutical and biotechnology companies, specialty pharmaceutical and generic drug companies, academic institutions, government agencies and research institutions, many of whom have greater financial, technical and human resources than us. We believe the key competitive factors that will affect the development and commercial success of EGRIFTA^® and our product candidates are efficacy, safety and tolerability profile, reliability, product acceptance by physicians and other healthcare providers, convenience of dosing, price and reimbursement. Also, the development of new treatment methods for the indications we are targeting could render our drugs non-competitive or obsolete. We are not aware of other GRF products being commercialized or in development for the reduction of excess abdominal fat in HIV-infected patients with lipodystrophy although we may face indirect competition for EGRIFTA^® from other drugs that may be prescribed by physicians. The use of these other drugs for the reduction of excess abdominal fat in HIV-infected patients with lipodystrophy has not been approved by the FDA nor any other regulatory authority.

We believe that competition in the area of muscle wasting in COPD patients is limited. We are aware of one other compound which has completed a Phase 1 clinical study in COPD muscle wasting (GOLD stage I and II). We may face indirect competition from other drugs such as anabolic steroids, testosterone and growth hormone that may be prescribed by physicians. However, these drugs have not been approved by the FDA for muscle wasting in COPD.

2.9 GOVERNMENT REGULATION

Overview

The research, development, manufacture and marketing of pharmaceutical products are governed by various governmental authorities throughout the world to ensure efficacy and safety.

Governmental authorities in the United States at the federal, state and local level, and other countries, extensively regulate, among other things, the research, development, testing, manufacture, quality control, approval, labeling, packaging, storage, record-keeping, promotion, advertising, distribution, marketing, export and import of products, such as EGRIFTA^® and other product candidates that we are developing. The process of obtaining regulatory approvals and the subsequent compliance with appropriate federal, state, local and foreign statutes and regulations require the expenditure of substantial time and financial resources. Failure to comply with the applicable United States or foreign requirements at any time during the product development process, approval process or after approval, may subject an applicant to administrative or judicial sanctions. Sanctions could include refusal to approve pending applications, withdrawal of an approval, a clinical hold, warning letters, product recalls, product seizures, total or partial suspension of production or distribution injunctions, fines, refusals of government contracts, restitution, disgorgement or civil or criminal penalties.

On November 10, 2010, the FDA approved EGRIFTA^® as the first approved treatment for excess abdominal fat in HIV-infected patients with lipodystrophy. Our other product candidates must receive regulatory approval from the FDA or other relevant foreign regulatory authorities before they may legally be marketed in the United States or other countries.

- 23 -

In Canada, these activities are governed by the provisions of the Food and Drugs Act and its regulations, which is enforced by the Therapeutic Products Directorate of the Health Products and Food Branch of Health Canada. We have not yet applied to market EGRIFTA^® in Canada.

United States — FDA Process

Before new pharmaceutical products may be sold in the United States, clinical trials of the product candidates must be conducted and the results submitted to the FDA for approval. The drug approval process requires, among other things, a demonstration of product safety and efficacy. Generally, a demonstration of safety and efficacy includes preclinical testing and clinical trials of product candidates. The testing, manufacture and marketing of pharmaceutical products in the United States requires the approval of the FDA. The FDA enforces laws and regulations which apply to preclinical testing, clinical trials, and manufacture of these products. The drug approval process in the United States is described in brief below.

Pre-Clinical Testing: Before testing of any compounds with potential therapeutic value in human subjects may begin in the United States, stringent government requirements for pre-clinical data must be satisfied. Pre-clinical testing includes laboratory evaluations of product pharmacology and toxicity in animal studies of the drug candidates. In parallel, the chemistry of the drug candidates must be elucidated and their manufacturing, including formulation and stability, clearly defined and controlled.

Investigational New Drug Application: Among other things, pre-clinical testing results obtained from animal studies and in vitro studies, are submitted to the FDA as part of an IND application and are reviewed by the FDA prior to the commencement of human clinical trials. An IND sponsor must also include a protocol detailing, among other things, the objectives of the initial clinical trial, the parameters to be used in monitoring safety and the effectiveness criteria to be evaluated if the initial clinical trial lends itself to an efficacy evaluation. Some preclinical testing may continue even after the IND is submitted. Unless the FDA objects to an IND (referred to as a clinical hold), the IND becomes effective 30 days following its receipt by the FDA. Once trials have commenced, the FDA may stop the trials at any time by placing them on “clinical hold” because of safety concerns or noncompliance. If the FDA issues a clinical hold, the IND sponsor and the FDA must resolve any outstanding concerns before the clinical study can begin. Accordingly, we cannot be sure that submission of a IND will result in the FDA allowing clinical trials to begin or that, once began, issues will not arise that suspend or terminate such trials.

Clinical Trials: Clinical trials involve the administration of the drug to healthy human volunteers or to patients under the supervision of a qualified investigator pursuant to an FDA-approved protocol. Each clinical trial must be conducted under the auspices of an Institutional Review Board, or IRB, that considers, among other things, ethical factors, the safety of human subjects and approves the patient informed consent, which must be agreed to by all participants prior to participation in the clinical trial. Once an IND is in effect, each new clinical protocol and any amendments to the protocol must be submitted to the FDA for review, and to the IRBs for approval. Protocols detail, among other things, the objectives of the clinical trial, dosing procedures, subject selection and exclusion criteria, and the parameters to be used to monitor subject safety. Human clinical trials are typically conducted in three sequential phases, although the phases may overlap with one another.

All phases of clinical trials must be conducted in conformance with Good Clinical Practices, or GCP, which are ethical and scientific quality standards for conducting, recording, and reporting clinical trials to assure that the rights, safety, and well-being of trial participants are protected, and the FDA’s regulations for the protection of human subjects.

Phase 1 Clinical Trials: Phase 1 clinical trials represent the initial administration of the investigational drug to a small group of healthy human subjects or, more rarely, to a group of select patients with the

- 24 -

targeted disease or disorder. The goal of Phase 1 clinical trials is typically to test for safety, dose tolerance, absorption, bio-distribution, metabolism, excretion and clinical pharmacology and, if possible, to gain early evidence regarding efficacy.

Phase 2 Clinical Trials: Phase 2 clinical trials involve a small sample of the actual intended patient population and seek to assess the efficacy of the drug for specific targeted indications, to determine dose response and the optimal dose range and to gather additional information relating to safety and potential adverse effects.

Phase 3 Clinical Trials: Once an investigational drug is found to have some efficacy and an acceptable safety profile in the targeted patient population, Phase 3 clinical trials are initiated to establish further clinical safety and efficacy of the investigational drug in a broader sample of the patient population with the target disease or disorder at geographically dispersed study sites in order to determine the overall risk-benefit ratio of the drug and to provide an adequate basis for regulatory approval and product labeling.

New Drug Application: All data obtained from a comprehensive development program including research and product development, manufacturing, pre-clinical and clinical trials and related information are submitted in an NDA to the FDA. In addition to reports of the trials conducted under the IND, the NDA includes information pertaining to the preparation of the new drug, chemistry manufacturing and controls, or CMC, analytical methods, details of the manufacture of finished products and proposed product packaging and labeling. The submission of an application is no guarantee that the FDA will find the application complete and accept it for filing. The FDA may refuse to file the application and request additional information rather than accept the application for filing, in which case, the application must be resubmitted with the supplemental information. The re-submitted application is also subject to review before the FDA accepts it for filing. Once an application is accepted for filing, an FDA review team — medical doctors, chemists, statisticians, microbiologists, pharmacologists, and other experts — evaluates whether the studies the sponsor submitted show that the drug is safe and effective for its proposed use and whether the applicant’s manufacturing complies with Good Manufacturing Practices, or GMP, to assure and preserve the product’s identity, strength, quality and purity. As part of the approval process, the FDA will inspect the facility or facilities where the product is manufactured. The FDA review process may be extended by FDA requests for additional information or clarification. In some cases, the FDA may decide to expedite the review of new drugs that are intended to treat serious or life threatening conditions and demonstrate the potential to address unmet medical needs.

As part of its review, the FDA may refer the application to an advisory committee for evaluation and a recommendation as to whether the application should be approved. The FDA is not bound by the recommendation of an advisory committee, but it generally follows such recommendations.

Under legislation enacted in 2007, the FDA may determine that a risk evaluation and mitigation strategy, or REMS, is necessary to ensure that the benefits of a new product outweigh its risks. If required, a REMS may include various elements, such as publication of a medication guide, patient package insert, a communication plan to educate healthcare providers of the drug’s risks, limitations on who may prescribe or dispense the drug, or other measures that the FDA deems necessary to assure the safe use of the drug.

In reviewing an NDA, the FDA may grant marketing approval, request additional information or deny the application if it determines the application does not provide an adequate basis for approval. The FDA may require larger or additional clinical trials, leading to unanticipated delay or expense. Even if such additional information and data are submitted, the FDA may ultimately decide that the NDA does not satisfy the criteria for approval. Data from clinical trials may be subject to different interpretation, and the FDA may interpret data differently than the applicant. The receipt of regulatory approval often

- 25 -

takes a number of years, involving the expenditure of substantial resources and depends on a number of factors, including the severity of the disease in question, the availability of alternative treatments and the risks and benefits demonstrated in clinical trials. The FDA may require, as a condition of approval, restricted distribution and use, enhanced labeling, special packaging or labeling, expedited reporting of certain adverse events, pre-approval of promotional materials, or restrictions on direct-to-consumer advertising or commitments to conduct additional research post-approval. The FDA will issue a complete response letter if the agency decides not to approve the NDA in its present form. The complete response letter usually describes all of the specific deficiencies in the NDA identified by the FDA. The deficiencies may be minor, for example, requiring labeling changes, or major, for example, requiring additional clinical studies. If a complete response letter is issued, the applicant may either resubmit the NDA, addressing all of the deficiencies identified in the letter, or withdraw the application. In addition, changes in FDA approval policies or requirements may occur, or new regulations may be promulgated, which may result in delay or failure to receive FDA approval.

Changes to an approved product, such as adding a new indication, making certain manufacturing changes, or changing manufacturers or suppliers of certain ingredients or components requires review and approval of the FDA.

Under the Hatch-Waxman Act, the U.S. Congress created an abbreviated FDA review process for generic versions of pioneer (brand name) drug products. The Hatch-Waxman Act requires NDA applicants and NDA holders to provide certain information about patents related to the drug for listing in the FDA’s publication, “Approved Drug Products with Therapeutic Equivalence Evaluations”, commonly known as the Orange Book. The Hatch-Waxman Act allows for, under certain circumstances, an abbreviated NDA, or ANDA, where an applicant seeks to determine that its proposed product is biologically equivalent to the reference drug. ANDA applicants do not have to conduct extensive clinical trials to prove the safety or efficacy of the drug product; rather, they are required to conduct less rigorous bioequivalence testing. Drugs approved in this way are commonly referred to as “generic equivalents” to the listed drug, are listed as such by the FDA, and can often be substituted by pharmacists under prescriptions written for the original listed drug. In addition, in certain cases, an application for marketing approval may include information regarding safety and efficacy of a proposed drug that comes from studies not conducted by or for the applicant and for which the applicant has not obtained a specific right to reference those studies. Such applications, known as a 505(b)(2) NDA, are permitted for new drug products that incorporate previously approved active ingredients, even if the proposed new drug incorporates an approved active ingredient in a novel formulation or for a new indication. Section 505(b)(2) also permits the FDA to rely for such approvals on literature or on a finding by the FDA of safety and/or efficacy for a previously approved drug product. In addition, a 505(b)(2) NDA for changes to a previously approved drug product may rely on the FDA’s finding of safety and efficacy of the previously approved product coupled with new clinical information needed by FDA to support the change. FDA approval of the NDA or ANDA is required before marketing of the product may begin in the United States.

The Pediatric Research Equity Act, or PREA, requires NDAs (or NDA supplements) for a new active ingredient, new indication, new dosage form, new dosing regimen, or new route of administration to contain data assessing the safety and efficacy for the claimed indication in all relevant pediatric subpopulations. Data to support dosing and administration also must be provided for each pediatric subpopulation for which the drug is safe and effective. FDA may grant deferrals for the submission of data, or full or partial waivers from the PREA requirements. Unless otherwise required by regulation, PREA does not apply to any drug for an indication for which orphan designation, as described below, has been granted.

If a product receives regulatory approval, the approval may be significantly limited to specific diseases and dosages or the indications for use may otherwise be limited, which could restrict the commercial value of the product. Further, the FDA may require that certain contraindications, warnings or

- 26 -

precautions be included in the product labeling. In addition, the FDA may require Phase 4 testing which involves clinical trials designed to further assess a drug safety and effectiveness and may require testing and surveillance programs to monitor the safety of approved products that have been commercialized.

Post-Approval Studies and Registries: Post-approval studies, also referred to as Phase 4 clinical trials are studies that are conducted after a product has been approved. These trials can be conducted for a number of purposes, including to collect long-term safety information or to collect additional data about a specific population. As part of a product approval, the FDA may require that certain Phase 4 studies be conducted post-approval, and in these cases these Phase 4 studies are called post-marketing commitments.

Adverse Event Reporting: Regulatory authorities track information on side effects and adverse events reported during clinical studies and after marketing approval. Non-compliance with FDA safety reporting requirements may result in FDA regulatory action that may include civil action or criminal penalties. Side effects or adverse events that are reported during clinical trials can delay, impede or prevent marketing approval. Similarly, adverse events that are reported after marketing approval can result in additional limitations being placed on the product’s use and, potentially, withdrawal or suspension of the product from the market. Furthermore, in September 2007 the Food and Drug Administration Amendments Act of 2007 was enacted, which provides the FDA with expanded authority over drug products after approval. This legislation enhances the FDA’s authority with respect to post-marketing safety surveillance including, among other things, the authority to require additional post-approval studies or clinical trials and mandate label changes as a result of safety findings, including the development and implementation of a REMS.

Orphan Drug Designation

Under the Orphan Drug Act, the FDA may grant orphan designation to a drug intended to treat a “rare disease or condition,” which is a disease or condition that affects fewer than 200,000 individuals in the United States, or more than 200,000 individuals in the United States and for which there is no reasonable expectation that the cost of developing and making a drug available in the United States for this type of disease or condition will be recovered from sales in the United States of the drug. Orphan product designation must be requested before submitting an NDA. After the FDA grants orphan drug designation, the identity of the therapeutic agent and its potential orphan use are disclosed publicly by the FDA. Orphan product designation does not convey any advantage in, or shorten the duration of the regulatory review and approval process.

If a drug that has orphan designation subsequently receives the first FDA approval for the disease or condition for which it has such designation, the product is entitled to orphan drug exclusivity, which means that the FDA may not approve any other applications to market the same drug for the same indication for seven years, except in limited circumstances, such as a showing of clinical superiority to the product with orphan exclusivity. Competitors, however, may receive approval of different drugs for the indication for which the orphan product has exclusivity or may obtain approval for the same drug but for a different indication for which the orphan product has exclusivity. Orphan product exclusivity also could block the approval of one of our product candidates for seven years if a competitor obtains approval of the same drug or if our product candidate is determined to be contained within the competitor’s product for the same indication or disease. If a drug designated as an orphan drug receives marketing approval for an indication broader than what is designated, it may not be entitled to orphan product exclusivity. Orphan drug status in the European Union has similar but not identical benefits in the European Union.

Expedited Development and Review Programs

The FDA has a fast track program that is intended to expedite or facilitate the process for reviewing new drugs that meet certain criteria. Specifically, new drugs are eligible for fast track designation if they are intended to treat a serious or life-threatening condition and demonstrate the potential to address unmet medical needs for the condition. Fast track designation applies to the combination of the product and the specific indication for which it is being studied. Unique to a fast track product, the FDA may consider for review sections of the NDA on a rolling basis before the complete application is submitted, if the sponsor provides a schedule for the submission of the sections of the NDA, the FDA agrees to accept sections of the NDA and determines that the schedule is acceptable, and the sponsor pays any required user fees upon submission of the first section of the NDA.

Any product submitted to the FDA for market, including a fast track program, may also be eligible for other types of FDA programs intended to expedite development and review, such as priority review and accelerated approval. Any product is eligible for priority review if it has the potential to provide safe and effective therapy where no satisfactory alternative therapy exists or a significant improvement in the treatment, diagnosis or prevention of a disease compared to marketed products. The FDA will attempt to direct additional resources to the evaluation of an application for a new drug designated for priority review in an effort to facilitate the review. Additionally, a product may be eligible for accelerated approval. Drug products studied for their safety and effectiveness in treating serious or life-threatening illnesses and that provide meaningful therapeutic benefit over existing treatments may receive accelerated approval, which means that they may be approved on the basis of adequate and well-controlled clinical studies establishing that the product has an effect on a surrogate endpoint that is reasonably likely to predict a clinical benefit, or on the basis of an effect on a clinical endpoint other than survival or irreversible morbidity. As a condition of approval, the FDA may require that a sponsor of a drug receiving accelerated approval perform adequate and well-controlled post-marketing clinical studies. In addition, the FDA currently requires as a condition for accelerated approval pre-approval of promotional materials, which could adversely impact the timing of the commercial launch of the product. Fast track designation, priority review and accelerated approval do not change the standards for approval but may expedite the development or approval process.

Non-U.S. Regulation

In addition to regulations in the United States, we will be subject to a variety of regulations governing clinical studies and commercial sales and distribution of our products in other jurisdictions around the world. Whether or not we obtain FDA approval for a product, we must obtain approvals from the comparable regulatory authorities of foreign countries before we can commence clinical studies or marketing of the product in those countries. The approval process varies from country to country and the time may be longer or shorter than that required for FDA approval. The requirements governing the conduct of clinical studies, product licensing, pricing and reimbursement vary greatly from country to country. In some international markets, additional clinical trials may be required prior to the filing or approval of marketing applications within the country.

In the European Union, medicinal products must be authorized either through the decentralized procedure by the competent authorities of the European Union Member States, or through the centralized procedure by the European Commission following an opinion by the EMA. The centralized procedure provides for the grant of a single marketing authorization that is valid for all European Union member states. The centralized procedure is compulsory for medicines produced by certain biotechnological processes, products with a new active substance indicated for the treatment of certain diseases such as neurodegenerative disorder or diabetes and products designated as orphan medicinal products, and optional for those products which are highly innovative or for which a centralized process is in the interest of patients. The decentralized approval procedure provides for approval by one or more “concerned” member states based on an assessment of an application

- 28 -

performed by one member state, known as the reference member state. Under the decentralized approval procedure, an applicant submits an application, or dossier, and related materials (draft summary of product characteristics, draft labeling and package leaflet) to the reference member state and concerned member states. The reference member state prepares a draft assessment and drafts of the related materials within 120 days after receipt of a valid application. Within 90 days of receiving the reference member state’s assessment report, each concerned member state must decide whether to approve the assessment report and related materials. If a member state objects to approval of the assessment report and related materials on the grounds of potential serious risk to public health, the disputed points may eventually be referred to the European Commission, whose decision is binding on all member states. In many European Union countries, pricing and reimbursement negotiations must also take place before the product is sold in their national market between the company marketing the product and the competent national authorities.

In order to obtain approval for commercializing new drugs in Canada, we must satisfy many regulatory conditions. We must complete preclinical studies in order to file a Clinical Trial Application, or CTA, in Canada. We then receive different clearance authorizations to proceed with Phase 1 clinical trials, which can then lead to Phase 2 and Phase 3 clinical trials. Once all three phases of trials are completed, we file a registration file named a New Drug Submission, or NDS, in Canada. If the NDS demonstrates that the product was developed in accordance with the regulatory authorities’ rules, regulations and guidelines and demonstrates favourable safety, efficacy and receives a risk/benefit analysis, then the regulatory authorities issue a notice of compliance, which allows us to market the product.

Good Manufacturing Practices

The FDA, the EMA, the competent authorities of the European Union Member States and other foreign regulatory agencies regulate and inspect equipment, facilities, and processes used in the manufacturing of pharmaceutical and biologic products prior to approving a product. Among the conditions for NDA or equivalent foreign approval is the requirement that the prospective manufacturer’s quality control and manufacturing procedures adhere to the FDA’s or other competent authorities’ current GMP. Before approval of an NDA or equivalent foreign approval, the FDA or other competent authority may perform a pre-approval inspection of a manufacturing facility to determine its compliance with GMP and other rules and regulations. In complying with GMP, manufacturers must continue to expend time, money and effort in the area of production and quality control to ensure full technical compliance. Similarly, NDA or equivalent foreign approval may be delayed or denied due to GMP non-compliance or other issues at contract sites or suppliers included in the NDA or equivalent foreign approval, and the correction of these shortcomings may be beyond our control. Facilities are also subjected to the requirements of other government bodies, such as the U.S. Occupational Safety & Health Administration and the U.S. Environmental Protection Agency.

If, after receiving clearance from regulatory agencies or competent authorities, a company makes certain changes in manufacturing equipment, location, or process, additional regulatory review and approval may be required. Our third-party suppliers must adhere to GMP and product-specific regulations enforced by the FDA or other competent authorities following product approval. The FDA, the European Union and other national competent authorities and regulatory agencies also conduct regular, periodic visits to re-inspect equipment, facilities and processes following the initial approval of a product. If, as a result of these inspections, it is determined that our suppliers’ equipment, facilities or processes do not comply with applicable regulations and conditions of product approval, regulatory agencies may seek civil, criminal or administrative sanctions and/or remedies against them, including the suspension of manufacturing operations.

- 29 -

Good Clinical Practices

The FDA, the EMA and other competent authorities promulgate regulations and standards, commonly referred to as GCP, for designing, conducting, monitoring, auditing and reporting the results of clinical trials to ensure that the data and results are accurate and that the trial participants are adequately protected. The FDA, the European Union and other foreign national competent authorities and regulatory agencies enforce GCP through periodic inspections of trial sponsors, principal investigators and trial sites. We rely on third-party service providers to conduct our clinical trials. If our study sites fail to comply with applicable GCP, the clinical data generated in our clinical trials may be deemed unreliable and relevant regulatory agencies may require us to perform additional clinical trials before approving our marketing applications.

Good Laboratory Practices

The FDA and other regulatory authorities promulgate regulations and standards, commonly referred to as Good Laboratory Practices, or GLP, for the conduct of non-clinical, commonly referred to as “preclinical,” non-human studies to provide a framework within which laboratory studies are planned, performed, monitored, recorded, reported and archived. Compliance with GLP is intended to assure regulatory authorities of the quality and integrity of the results obtained during the preclinical studies. Before we may test our product candidates on humans in clinical trials, we must first conduct preclinical testing, including animal studies, in accordance with GLP. The FDA or other regulatory authorities may inspect the testing facilities where our pre-clinical studies are conducted. The results of preclinical studies in the United States, Europe or other countries, not conducted in accordance with GLP, might be inadmissible in support of an NDA in the United States, or comparable applications in other countries.

United States Sales and Marketing

Our commercial partner, EMD Serono, will be subject to various United States regulations relating to the sales and marketing of EGRIFTA^® in the United States. The FDA regulates all advertising and promotion activities for products under its jurisdiction both prior to and after approval. A company can make only those claims relating to safety and efficacy that are approved by the FDA. Drugs may be promoted only for the approved indications and in accordance with the provisions of the approved label. The FDA actively enforces the laws and regulations prohibiting the promotion of off-label uses, and a company that is found to have improperly promoted off-label uses may be subject to significant sanctions. The FDA does not regulate the practice of medicine by physicians in their choice of treatment, but FDA regulations do impose stringent restrictions on manufacturers’ communications regarding off-label uses. Failure to comply with applicable FDA requirements may subject a company to adverse publicity, enforcement action by the FDA, corrective advertising, and the full range of civil and criminal penalties available to the FDA.

Marketing of EGRIFTA^® within the United States is also subject to various federal and state laws pertaining to health care “fraud and abuse,” including anti-kickback laws and false claims laws. Anti-kickback laws make it illegal for a prescription drug manufacturer to solicit, offer, receive, or pay any remuneration in exchange for, or to induce, the referral of business, including the purchase or prescription of a particular drug. Due to the breadth of the statutory provisions and the absence of guidance in the form of regulations and very few court decisions addressing industry practices, it is possible that our commercial partners’ practices might be challenged under anti-kickback or similar laws. False claims laws prohibit anyone from knowingly and willingly presenting, or causing to be presented for payment to third-party payors (including Medicare and Medicaid) claims for reimbursed drugs or services that are false or fraudulent.

- 30 -

In addition, several states require that companies implement compliance programs or comply with industry ethics codes, adopt spending limits, and report to state governments any gifts, compensation, and other remuneration provided to physicians. The recently enacted health care reform legislation will require record-keeping and disclosure to the federal government of payments to physicians commencing in 2012. Any activities relating to the sale and marketing of our products may be subject to scrutiny under these laws. Violations of fraud and abuse laws may be punishable by criminal and/or civil sanctions, including fines and civil monetary penalties, as well as the possibility of exclusion from federal health care programs (including Medicare and Medicaid). If the government were to allege or convict our commercial partner of violating these laws, our business could be harmed. In addition, there is ability for private individuals to bring similar actions.

Further, there are an increasing number of state laws that require manufacturers to make reports to states on pricing and marketing information. Our activities could be subject to challenge for the reasons discussed above and due to the broad scope of these laws and the increasing attention being given to them by law enforcement authorities.

2.10 PHARMACEUTICAL PRICING AND REIMBURSEMENT

In the United States and in other countries, sales of EGRIFTA^® and our other product candidates will depend in part on the availability of reimbursement from third-party payors. Third-party payors include government health administrative authorities (such as the Centers for Medicare & Medicaid Services in the United States), managed care providers, private health insurers and other organizations. We believe EGRIFTA^® will achieve a high degree of physician and payor acceptance, driven by our product’s safety and efficacy, the lack of approved alternative therapies for these patients and the prominent medical and social need to treat HIV/AIDS patients.

However, these third-party payors are increasingly challenging the price and examining the cost-effectiveness of medical products and services. In addition, significant uncertainty exists as to the reimbursement status of newly approved healthcare product candidates. We, or our commercial partners, may need to conduct expensive pharmacoeconomic studies in order to demonstrate the cost-effectiveness of EGRIFTA^® or our other product candidates. EGRIFTA^® or our other product candidates may not be considered cost-effective. It is time consuming and expensive for us, and our commercial partners, to seek reimbursement from third-party payors. Reimbursement may not be available or sufficient to allow us to sell EGRIFTA^® or our other product candidates on a competitive and profitable basis.

United States

Pursuant to our agreement with EMD Serono, they are responsible for identifying and obtaining possible reimbursements under such government programs in the United States. The U.S. Congress and state legislatures from time to time propose and adopt initiatives aimed at cost containment, which could impact our ability to sell our products profitably. For example, in March 2010, President Obama signed into law the Patient Protection and Affordable Care Act, and the associated reconciliation bill, which we refer to collectively as the Health Care Reform Law, a sweeping law intended to broaden access to health insurance, reduce or constrain the growth of healthcare spending, enhance remedies against fraud and abuse, add new transparency requirements for healthcare and health insurance industries, impose new taxes and fees on the health industry and impose additional health policy reforms. Effective October 1, 2010, the Health Care Reform Law revises the definition of “average manufacturer price” for reporting purposes, which could increase the amount of Medicaid drug rebates to states once the provision is effective. Further, beginning in 2011, the new law imposes a significant annual fee on companies that manufacture or import certain branded prescription drug products and biologic agents. Substantial new provisions affecting compliance also have been enacted, which may require us, or EMD Serono, to modify our business

- 31 -

practices with healthcare practitioners. We will not know the full effects of the Health Care Reform Law until applicable federal and state agencies issue regulations or guidance under the new law. Although it is too early to determine the effect of the Health Care Reform Law, the new law appears likely to continue the pressure on pharmaceutical pricing, especially under the Medicare program, and also may increase our regulatory burdens and operating costs.

The Medicare Prescription Drug, Improvement, and Modernization Act of 2003, or MMA, imposed new requirements for the distribution and pricing of prescription drugs for Medicare beneficiaries, and included a major expansion of the prescription drug benefit under a new Medicare Part D. Medicare Part D went into effect on January 1, 2006. Under Part D, Medicare beneficiaries may enroll in prescription drug plans offered by private entities which will provide coverage of outpatient prescription drugs. Part D plans include both stand-alone prescription drug benefit plans and prescription drug coverage as a supplement to Medicare Advantage plans. Unlike Medicare Part A and B, Part D coverage is not standardized. Part D prescription drug plan sponsors are not required to pay for all covered Part D drugs, and each drug plan can develop its own drug formulary that identifies which drugs it will cover and at what tier or level. However, Part D prescription drug formularies must include drugs within each therapeutic category and class of covered Part D drugs, though not necessarily all the drugs in each category or class. Any formulary used by a Part D prescription drug plan must be developed and reviewed by a pharmacy and therapeutic committee.

It is not clear what effect the MMA will have on the prices paid for EGRIFTA^® and our other product candidates. Some studies indicate that Part D lowered the average price and increased the utilization of prescription drugs by Medicare beneficiaries. Government payment for some of the costs of prescription drugs may increase demand for products for which we receive marketing approval. However, any negotiated prices for our products covered by a Part D prescription drug plan will likely be lower than the prices we might otherwise obtain. Moreover, while the MMA applies only to drug benefits for Medicare beneficiaries, private payors often follow Medicare coverage policy and payment limitations in setting their own payment rates. Any reduction in payment that results from the MMA may result in a similar reduction in payments from non-governmental payors.

There are also laws that govern a company’s eligibility to participate in Medicare and Medicaid reimbursements. For example, a company may be debarred from participation if it is found to have violated federal anti-kickback laws, which could have a significant effect on a company’s ability to operate its business.

The cost of pharmaceuticals continues to generate substantial governmental and third-party payor interest. We expect that the pharmaceutical industry will experience pricing pressures due to the trend toward managed healthcare, the increasing influence of managed care organizations, and additional legislative proposals. Indeed, we expect that there will continue to be a number of U.S. federal and state proposals to implement governmental pricing controls and limit the growth of healthcare costs, including the cost of prescription drugs. At the present time, Medicare is prohibited from negotiating directly with pharmaceutical companies for drugs. However, the U.S. Congress is considering passing legislation that would lift the ban on federal negotiations. While we cannot predict whether such legislative or regulatory proposals will be adopted, the adoption of such proposals could harm our business, financial condition and results of operations.

Some third-party payors also require pre-approval of coverage for new or innovative drug therapies before they will reimburse healthcare providers that use such therapies. While we cannot predict whether any proposed cost-containment measures will be adopted or otherwise implemented in the future, the announcement or adoption of these proposals could have a material adverse effect on our ability to obtain adequate prices for our product candidates and operate profitably.

- 32 -

Europe and other countries covered by our agreements

Outside of the United States, sales of EGRIFTA^® and our other product candidates will depend in part on the availability and level of reimbursement from third-party payers. Third-party payers can be public or private or a combination of both. In order to obtain public reimbursement, prescription drugs are often evaluated by specialized bodies in a country. This process is in many cases independent of marketing approval and the time to carry out the evaluation differs in each country, often extending beyond the initial regulatory approval date of the drug.

The requirements and aspects considered during the assessment of a new prescription drug are not necessarily the same in each country and are given different weight depending on the countries’ attitudes towards providing public healthcare and the government’s willingness to pay for these new drugs. We or our commercial partners could be required to conduct specific health economic and other studies or analyses in order to satisfy such requirements. The decision to comply with such requirements will depend on the prospects of obtaining a positive opinion and the costs involved in the process and the profitability of the market.

In many jurisdictions, pricing plays an important role in the evaluation of prescription drugs for reimbursement and in most cases, there are price controls that can include, but are not limited to, reference pricing to drugs sold within the country and in other countries, the evaluation of what a fair price would be based on the condition that is being treated and innovative quality of the new drug.

Many countries, particularly in Europe, have initiated cost-cutting measures which have been reflected in reduced budgets for drugs, higher discounts imposed on manufacturers and price negotiations between authorities and manufacturers among other actions. We expect the current reimbursement evaluation process and pricing policies to keep evolving in ways that we may not foresee.

In Latin America, Brazil has a formal price procedure through Agência Nacional de Vigilância Sanitoria (ANVISA) which determines the price of a pharmaceutical based on five reference countries, including the United States. However, there is uncertainty in pricing of pharmaceutical drugs in Latin America in general.

Pursuant to our agreements with Sanofi and Ferrer, each is responsible for identifying and obtaining possible reimbursements under such government programs in their respective territories.

2.11 EMPLOYEES

As at November 30, 2010, we had 99 employees, all of whom were employed in Canada. All of our employees are engaged in administration, finance, research and development, regulatory and business development functions. None of our employees are unionized. We believe the relations with our employees are good.

2.12 FACILITIES

We carry out our activities at 2310 Alfred-Nobel Boulevard in the Technoparc Montréal in Ville Saint-Laurent, Québec, Canada. We lease a 36,400 square-foot building, which houses both offices and laboratories which enable us to conduct small-scale peptide manufacturing, discovery and manage preclinical and clinical research.

The facilities contain laboratories which enable us to conduct small-scale peptide manufacturing, discovery and preclinical research. Peptide compounds are synthesized by our pharmaceutical development department using manual and semiautomatic methods with reactors of different sizes (from 50 to 8000 ml) and also a 12-channel automated peptide synthesizer. The peptides are purified using preparative high performance liquid chromatography, or HPLC, comprising either the Dynamic

- 33 -

Axial Compression column, or a number of pre-packed columns. The final peptides are dried to a solid form using lyophilization equipment. The analyses on the quality of the peptides are done using a variety of equipment including HPLC instruments Agilent 1100 and 1200, UV spectrophotometers and a water content analyzer.

We also have discovery and preclinical research laboratories which include two cell culture rooms and several chemical hoods. A Mesoscale chemiluminometer (Sector PR100) is used for sensitive immunological and cell-based assays. Several HPLC instruments for preformulation and purity determinations, scintillation spectrophotometers for radioactivity measurements, and fluorospectrophotometers and colorimetric plate readers for cell-based screens and immunoassays enable in-house discovery and preclinical research. A designated laboratory section is equipped to conduct studies according to GLP.

2.13 ENVIRONMENT

To our knowledge, at our current development stage, environmental protection requirements do not have a significant financial or operational impact on our capital expenditures, income or competitive position within the normal course of our operating activities.

ITEM 3 RISK FACTORS

Before you invest in our common shares, you should understand the high degree of risk involved. You should consider carefully the following risks and uncertainties described below before you decide to purchase our common shares. The following risks may adversely impact our business, financial condition, operating results and prospects. Additional risks and uncertainties, including those that we do not know about or that we currently believe are immaterial, may also adversely affect our business, financial condition, operating results or prospects. As a result, the trading price of our common shares could decline and you could lose all or part of your investment.

3.1 RISKS RELATED TO THE COMMERCIALIZATION OF OUR PRODUCT AND PRODUCT CANDIDATES

Our commercial success depends largely on the commercialization of EGRIFTA^®; the failure of EGRIFTA^® to obtain commercial acceptance would have a material adverse effect on us.

Our ability to generate revenues in the future is primarily based on the commercialization of EGRIFTA^® for the reduction of excess abdominal fat in HIV-infected patients with lipodystrophy. In the short-term, these revenues should be primarily derived from the U.S. market alone. Although we have entered into a collaboration and licensing agreement with EMD Serono for the commercialization of EGRIFTA^® in the United States, there can be no assurance that EGRIFTA^® will be successfully commercialized in the United States, or in any other country. Although we are developing other peptides, all of them are at earlier stages of development and none of them may reach the clinical trial phase, obtain regulatory approval or, even if approved, be successfully commercialized.

The overall commercialization success of EGRIFTA^® for the reduction of excess abdominal fat in HIV-infected patients with lipodystrophy will depend on several factors, including:

	•		receipt of regulatory approvals for EGRIFTA^® from regulatory agencies in the territories other than the United States in which we wish to expand the commercialization of tesamorelin;

	•		market acceptance of EGRIFTA^® by the medical community, patients and third-party payors (such as governmental health administration authorities and private health coverage insurers);

	•		the amount of resources devoted by our commercial partners to commercialize EGRIFTA^® in their respective territories;

	•		maintaining manufacturing and supply agreements to ensure the availability of commercial quantities of EGRIFTA^® through validated processes;

	•		the number of competitors in our market; and

	•		protecting and enforcing our intellectual property and avoiding patent infringement claims.

The inability to successfully commercialize EGRIFTA^® in the United States for the reduction of excess abdominal fat in HIV-infected patients with lipodystrophy in the short term would delay our capacity to generate revenues and would have a material adverse effect on our financial condition and operating results.

- 35 -

We are or will be dependent on a limited number of collaboration and licensing agreements for the commercialization of EGRIFTA^® in the United States, Europe, Latin America, Africa and the Middle East. These agreements place the commercialization of EGRIFTA^® in these markets outside of our control.

Although our collaboration and licensing agreements with EMD Serono, Sanofi and Ferrer contain provisions governing their respective responsibilities as partners for the commercialization of EGRIFTA^® in their respective territories, our dependence on these partners to commercialize EGRIFTA^® is subject to a number of risks, including:

	•		our limited control of the amount and timing of resources that our commercial partners will be devoting to the commercialization, marketing and distribution of tesamorelin, including obtaining patient reimbursement for EGRIFTA^®, which could adversely affect our ability to obtain or maximize our royalty payments;

	•		disputes or litigation that may arise between us and our commercial partners, which could adversely affect the commercialization of tesamorelin, all of which would divert our management’s attention and our resources;

	•		our commercial partners not properly defending our intellectual property rights or using them in such a way as to expose us to potential litigation, which could, in both cases, adversely affect the value of our intellectual property rights; and

	•		corporate reorganizations or changes in business strategies of our commercial partners, which could adversely affect a commercial partner’s willingness or ability to fulfill its obligations under its respective agreement.

Our collaboration and licensing agreements may be terminated by our partners in the event of a breach by us of our obligations under such agreements, including our obligation to supply EGRIFTA^®, for which we rely on third parties. Our collaboration and licensing agreement with EMD Serono can also be terminated by EMD Serono for their convenience on 180 days notice to us. Such a termination could have an adverse effect on our revenues related to the commercialization of EGRIFTA^® in the United States. In addition, EMD Serono has listed a patent held by one of its affiliates in the Orange Book under the Hatch-Waxman Act with respect to EGRIFTA^® in HIV-associated lipodystrophy. In the event of a termination of our agreement with EMD Serono, EMD Serono could assert that such patent would be infringed by our continued sale of EGRIFTA^® in the United States. Any such assertion would divert our management’s attention and, if successful, could expose us to damages or require us to obtain a license from EMD Serono in order to continue selling EGRIFTA^® in the United States, all of which could have a material adverse effect on our results of operations, cash flows and financial conditions.

If any one of our commercial partners terminates their agreement with us or fails to effectively commercialize EGRIFTA^®, for any of the foregoing or other reasons, we may not be able to replace the commercial partner and any of these events would have a material adverse effect on our business, results of operations and our ability to achieve future profitability, and could cause our share price to decline.

We rely on third parties for the manufacture and supply of EGRIFTA^® and tesamorelin and such reliance may adversely affect us if the third parties are unable or unwilling to fulfill their obligations.

The manufacture of pharmaceutical products requires significant expertise and capital investment, including the development of advanced manufacturing techniques and process controls. We do not

- 36 -

own or operate manufacturing facilities for the production of tesamorelin or any of our other product candidates, nor do we have plans to develop our own manufacturing operations in the foreseeable future. We currently rely on third parties to manufacture and supply all of our required raw materials, drug substance and drug product for our preclinical research, clinical trials and commercial sales. For tesamorelin for clinical studies and EGRIFTA^® for commercial sales, we are currently using, and relying on, single suppliers and single manufacturers for starting materials and the final drug substance. Although potential alternative suppliers and manufacturers have been identified, we have not qualified these vendors to date and no assurance can be given that such suppliers will be qualified in the future or receive necessary regulatory approval.

Our reliance on third-party manufacturers exposes us to a number of risks. We may be subject to delays in or suspension of the manufacturing of EGRIFTA^® and tesamorelin if a third-party manufacturer:

	•		becomes unavailable to us for any reason, including as a result of the failure to comply with GMP regulations;

	•		experiences manufacturing problems or other operational failures, such as equipment failures or unplanned facility shutdowns required to comply with GMP or damage from any event, including fire, flood, earthquake, business restructuring or insolvency; or

	•		fails to perform its contractual obligations under our agreement, such as failing to deliver the quantities requested on a timely basis.

Any delay in or suspension of the supply of EGRIFTA^® could delay or prevent the sale of EGRIFTA^® and, accordingly, adversely affect our revenues and results of operations. In addition, any manufacturing delay or delay in delivering EGRIFTA^® may result in our being in default under our collaboration agreements. If the damage to a supplier’s manufacturer facility is extensive, or, for any reason, it does not operate in compliance with GMP or the third-party manufacturer is unable or refuses to perform its obligations under our agreement, we would need to find an alternative third-party manufacturer. The selection of a replacement third-party manufacturer would be time-consuming and costly since we would need to validate the manufacturing facility of such new third-party manufacturer. The validation process would include an assessment of the capacity of such third-party manufacturer to produce the quantities that we may request from time to time, the manufacturing process and its compliance with GMP. In addition, the third-party manufacturer would have to familiarize itself with our technology. Any delay in finding an alternative third-party manufacturer of tesamorelin and EGRIFTA^® could result in a shortage of such analogue or product, which could materially adversely affect our business and results of operations.

Any delay in or suspension of the supply of tesamorelin could delay or interrupt the conduct of clinical trials of our new clinical programs relating to muscle wasting in COPD.

Even though we have received regulatory approval for EGRIFTA^® in the United States, we still may not be able to successfully commercialize it if we do not gain market acceptance and the revenue that we generate from its sales, if any, may be limited.

The commercial success of EGRIFTA^® or any future products for which we obtain marketing approval from the FDA or other regulatory authorities, will depend upon the acceptance of such product by the medical community, including physicians, patients and health care payors. The degree of market acceptance of any of our products will depend on a number of factors, including:

•

acceptance of the product by physicians and patients as safe and effective treatments and addressing a significant unmet medical need;

- 37 -

	•		product price;

	•		the effectiveness of our sales and marketing efforts (or those of our commercial partners);

	•		storage requirements and ease of administration;

	•		dosing regimen;

	•		safety and efficacy;

	•		prevalence and severity of side effects;

	•		competitive products;

	•		the ability to obtain and maintain sufficient third-party coverage or reimbursement from government health care programs, including Medicare and Medicaid, private health insurers and other third-party payors; and

	•		the willingness and ability of patients to pay out-of-pocket in the absence of third-party coverage.

If EGRIFTA^® does not achieve an adequate level of acceptance by physicians, health care payors and patients, we may not generate sufficient revenue from this product, and we may not be able to achieve profitability. Our efforts, and the efforts of our commercial partners, to educate the medical community and third-party payors on the benefits of tesamorelin may require significant resources and may never be successful.

We have no internal sales, marketing or distribution capabilities so we must rely on strategic alliance agreements with third parties for the sale and marketing of EGRIFTA^® or any future products.

We currently have no internal sales, marketing or distribution capabilities and we rely on our commercial partners to market and sell EGRIFTA^® in their respective territories. Our agreements with our commercial partners contain termination provisions which, if exercised, could delay or suspend the commercialization of EGRIFTA^® or any future products.

In the event of any such termination, in order to continue commercialization, we would be required to build our own sales force or enter into agreements with third parties to provide such capabilities. We currently have limited marketing capabilities and we have limited experience in developing, training or managing a sales force. The development of a sales force would be costly and would be time-consuming given the limited experience we have in this area. To the extent we develop a sales force, we could be competing against companies that have more experience in managing a sales force than we have and that have access to more funds than we with which to manage a sales force. Consequently, there can be no assurance that a sales force which we develop would be efficient and would maximize the revenues derived from the sale of EGRIFTA^® or any future products.

We are substantially dependent on revenues from EGRIFTA^®.

Our current and future revenues depend substantially upon sales of EGRIFTA^® by our commercial partners, EMD Serono, Sanofi and Ferrer. Any negative developments relating to this product, such as safety or efficacy issues, the introduction or greater acceptance of competing products, including those marketed and sold by our commercial partners, or adverse regulatory or legislative developments, would have a material adverse effect on our business, prospects and results of

- 38 -

operations. Although we continue to develop additional product candidates for commercialization, we expect to be substantially dependent on sales from EGRIFTA^® for the foreseeable future. A decline in sales from this product would have a material adverse affect on our business and financial condition.

Our levels of revenues are highly dependent on obtaining patient reimbursement for EGRIFTA^®.

Market acceptance and sales of EGRIFTA^® will substantially depend on the availability of reimbursement from third party payors such as governmental authorities, including U.S. Medicare and Medicaid, managed care providers, and private insurance plans and may be affected by healthcare reform measures in the United States and elsewhere. Government authorities and third-party payors, such as private health insurers and health maintenance organizations, decide which medications they will pay for and establish reimbursement levels. A primary trend in the U.S. healthcare industry and elsewhere is cost containment. Government authorities and these third-party payors have attempted to control costs by limiting coverage and the amount of reimbursement for particular medications. Increasingly, third-party payors have been challenging the prices charged for products.

Under our agreements with our commercial partners, they are responsible for seeking reimbursement of EGRIFTA^® in their respective territories and as a result we have no control over whether or what level of reimbursement is achieved.

We cannot be sure that reimbursement by insurers, government or other third parties will be available for EGRIFTA^® and, if reimbursement is available, the level of reimbursement provided to patients. Reimbursement may impact the demand for, or the price of, EGRIFTA^® and our future products for which we obtain marketing approval. If reimbursement is not available or is available only in limited amount, our commercial partners may not be able to successfully commercialize EGRIFTA^® or our future products and it will have a material adverse effect on our revenues and royalties, business and prospects.

A variety of risks associated with our international business relationships could materially adversely affect our business.

International business relationships in the United States, Europe, Latin America, Africa, the Middle East and elsewhere subject us to additional risks, including:

	•		differing regulatory requirements for drug approvals in foreign countries;

	•		potentially reduced protection for intellectual property rights;

	•		potential third-party patent rights in foreign countries;

	•		the potential for so-called parallel importing, which is what happens when a local seller, faced with high or higher local prices, opts to import goods from a foreign market, with low or lower prices, rather than buying them locally;

	•		unexpected changes in tariffs, trade barriers and regulatory requirements;

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

	•		compliance with tax, employment, immigration and labour laws for employees traveling abroad;

- 39 -

	•		foreign taxes;

	•		foreign exchange contracts and foreign currency fluctuations, which could result in increased operating expenses and reduced revenue, and other obligations incident to doing business in another country;

	•		workforce uncertainty in countries where labour unrest is more common than in the United States and Canada;

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

	•		business interruptions resulting from geo-political actions, including war and terrorism, or natural disasters, including earthquakes, volcanoes, typhoons, floods, hurricanes and fires.

These and other risks of international business relationships may materially adversely affect our business, prospects, results of operations and financial condition.

Governments outside the United States tend to impose strict price controls, which may adversely affect our revenues, if any.

In several countries, including countries which are in Europe, Latin America, Africa, and the Middle East, the pricing of prescription drugs may be subject to governmental control. In these countries, pricing negotiations with governmental authorities can take considerable time and delay the marketing of a product. To obtain reimbursement or pricing approval in some countries, a clinical trial that compares the cost-effectiveness of a product candidate to other available therapies may be required. If reimbursement of our product is unavailable or limited in scope or amount, or if pricing is set at unsatisfactory levels, our commercial partners may not be willing to devote resources to market and commercialize EGRIFTA^® or may decide to cease marketing such product. In such case, our business, prospects and results of operations could be materially adversely affected.

We face competition and the development of new products by other companies could materially adversely affect our business and products.

The biopharmaceutical and pharmaceutical industries are highly competitive and we must compete with pharmaceutical companies, biotechnology companies, academic and research institutions as well as governmental agencies for the development and commercialization of products, most of which have substantially greater financial, technical and personnel resources than us. Although we believe that we have no direct competitors for the reduction of excess abdominal fat in HIV-infected patients with lipodystrophy, we could face indirect competition from other companies developing and/or commercializing metabolic products and/or other products that reduce or eliminate the occurrence of lipodystrophy.

In the other clinical programs that we are currently evaluating for development, there may exist companies that are at a more advanced stage of developing a product to treat the diseases for which we are evaluating clinical programs. Some of these competitors could have access to capital resources, research and development personnel and facilities that are superior to ours. In addition, some of these competitors could be more experienced than we are in the development and commercialization of medical products and already have a sales force in place to launch new products. Consequently, they may be able to develop alternative forms of medical treatment which could compete with our products and which could be commercialized more rapidly and effectively than our products.

- 40 -

If we fail to comply with government regulations regarding the import and export of products and raw materials, we could be subject to fines, sanctions and penalties that could adversely affect our ability to operate our business.

We import and export products and raw materials from and to several jurisdictions around the world. This process requires us and our commercial partners to operate in a number of jurisdictions with different customs and import/export regulations. The regulations of these countries are subject to change from time to time and we cannot predict the nature, scope or impact of these changes upon our operations. We and our commercial partners are subject to periodic reviews and audits by U.S. and foreign authorities responsible for administering these regulations. To the extent that we or our commercial partners are unable to successfully defend against an audit or review, we may be required to pay assessments, penalties and increased duties, which may, individually or in the aggregate, negatively impact our business, operating results and financial condition.

3.2 RISKS RELATED TO THE REGULATORY REVIEW PROCESS

Even after regulatory approval has been obtained regulatory agencies may impose limitations on the indicated uses for which our products may be marketed, subsequently withdraw approval or take other actions against us that would be adverse to our business.

Even though we have obtained marketing approval of EGRIFTA^® in the United States, the FDA and regulatory agencies in other countries have the ability to limit the indicated use of a product. Also, the manufacture, marketing and sale of our products will be subject to ongoing and extensive governmental regulation in the country in which we intend to market our products. For example, although we obtained marketing approval of EGRIFTA^® for the reduction of excess abdominal fat in HIV-infected patients with lipodystrophy in the United States, the marketing of EGRIFTA^® will be subject to extensive regulatory requirements administered by the FDA, such as adverse event reporting and compliance with marketing and promotional requirements. The FDA has also requested that we comply with certain post-approval requirements in connection with the approval of EGRIFTA^® for the reduction of excess abdominal fat in HIV-infected patients with lipodystrophy, namely, the development of a single vial formulation of EGRIFTA^® (the development of a new presentation of the same formulation), a long-term observational safety study using EGRIFTA^®; and a Phase 4 clinical trial. Although we have received marketing approval from the FDA of tesamorelin for the reduction of excess abdominal fat in HIV-infected patients with lipodystrophy, there can be no guarantee that regulatory agencies in other countries will approve tesamorelin for this treatment in their respective countries.

Our third party manufacturing facilities for EGRIFTA^® will also be subject to continuous reviews and periodic inspections and approval of manufacturing modifications by regulatory agencies, including the FDA. The facilities must comply with GMP regulations. The failure to comply with FDA requirements can result in a series of administrative or judicial sanctions or other setbacks, including:

	•		restrictions on the use of the product, manufacturers or manufacturing processes;

	•		warning letters;

	•		civil or criminal penalties;

	•		fines;

	•		injunctions;

	•		product seizures or detentions;

- 41 -

	•		import or export bans or restrictions;

	•		product recalls and related publicity requirements;

	•		suspension or withdrawal of regulatory approvals;

	•		total or partial suspension of production; and

	•		refusal to approve pending applications for marketing approval of new product candidates or supplements to approved applications.

Addressing any of the foregoing or any additional requirements of the FDA or other regulatory authorities may require significant resources and could impair our ability to successfully commercialize our product candidates.

To date, we do not have the required regulatory approvals to commercialize EGRIFTA^® outside of the United States and cannot guarantee that we will obtain such regulatory approvals or that any of our product candidates will be approved for commercialization in any country, including the United States.

The commercialization of EGRIFTA^® outside of the United States and our future products first requires the approval of the regulatory agencies in each of the jurisdictions where we intend to sell such products. In order to obtain the required approvals, we must demonstrate, following preclinical and clinical studies, the safety, efficacy and quality of a product.

The rules and regulations relating to the approval of a new drug are complex and stringent. Although we have received marketing approval in the United States from the FDA for EGRIFTA^®, there can be no guarantee that regulatory agencies in other territories will approve EGRIFTA^® in their respective countries.

All of our product candidates are subject to preclinical and clinical studies. If the results of such studies are not positive, we may not be in a position to make any filing to obtain the regulatory approval for the product candidate or, even where a product candidate has been filed for approval, we may have to conduct additional clinical trials or testing on such product candidate in an effort to obtain results that further support the safety and efficacy of such product candidate. Such studies are often costly and may also delay a filing or, where additional studies or testing are required after a filing has been made, the approval of a product candidate.

While an application for a new drug is under review by a regulatory agency, it is standard for such regulatory agency to ask questions regarding the application that was submitted. If these questions are not answered quickly and in a satisfactory manner, the marketing approval of the product candidate subject to the review and its commercialization could be delayed or, if the questions are not answered in a satisfactory manner, denied. If EGRIFTA^® is not approved by the appropriate regulatory agencies for commercialization outside of the United States, our capacity to generate revenues in the long-term will be impaired and this will have an adverse effect on our financial condition and our operating results.

Obtaining regulatory approval is subject to the discretion of regulatory agencies in each relevant jurisdiction. Therefore, even if we obtain regulatory approval from one agency, or succeed in filing the equivalent of an NDA, in other countries, or have obtained positive results relating to the safety and efficacy of a product candidate, a regulatory agency may not accept the filing or the results contained therein as being conclusive evidence of the safety and efficacy of a product candidate in order to allow us to sell the product candidate in its country. A regulatory agency may require that additional

- 42 -

tests on the safety and efficacy of a product candidate be conducted prior to granting approval of such product candidate. These additional tests may delay the approval of such product candidate, can have a material adverse effect on our financial condition and results of operations based on the type of additional tests to be conducted and may not necessarily lead to the approval of the product candidate.

We have only obtained FDA approval for EGRIFTA^® and we must complete several preclinical studies and clinical trials for our other product candidates which may not yield positive results and, consequently, could prevent us from obtaining regulatory approval.

Obtaining FDA approval for the commercialization of drug products requires a demonstration through preclinical studies and clinical trials that the drug is safe and effective. All of our product candidates are at the discovery stage, except our peptide for the treatment of AKI, which is in preclinical development. In addition, in order to market tesamorelin for other indications, we will need to demonstrate its effectiveness and safety through additional studies and clinical trials. Favourable results in our trials of tesamorelin for the reduction of excess abdominal fat in HIV-infected patients with lipodystrophy may not be predictive of the efficacy and safety results in our Phase 2 clinical trials of tesamorelin for the treatment of muscle wasting in COPD.

If any of our preclinical studies or clinical trials fail to show positive efficacy data or result in adverse patient reactions, we may be required to perform additional preclinical studies or clinical trials, to extend the term of our studies and trials, to increase the number of patients enrolled in a given trial or to undertake ancillary testing. Any of these events could cause an increase in the cost of product development, delay filing of an application for marketing approval or result in the termination of a study or trial and, accordingly, could cause us to cease the development of a product candidate. In addition, the future growth of our business could be negatively impacted since there can be no guarantee that we will be able to develop new compounds, license or purchase compounds or product candidates that will result in marketed products.

Recently enacted and future legislation may increase the difficulty and cost for us to obtain marketing approval of and commercialize our product candidates and affect the prices we may obtain.

In the United States and some foreign jurisdictions, there have been a number of legislative and regulatory changes and proposed changes regarding the healthcare system that could prevent or delay marketing approval for our product candidates, restrict or regulate post-approval activities and affect our ability to profitably sell EGRIFTA^® or any of our other product candidates for which we intend to seek marketing approval.

Legislative and regulatory proposals have been made to expand post-approval requirements and restrict sales and promotional activities for pharmaceutical products. We are not sure whether additional legislative changes will be enacted, or whether the FDA regulations, guidance or interpretations will be changed, or what the impact of such changes on the marketing approvals of our product candidates, if any, may be. In addition, increased scrutiny by the U.S. Congress of the FDA’s approval process may significantly delay or prevent marketing approval, as well as subject us to more stringent product labeling and post-marketing testing and other requirements.

In the United States, the MMA changed the way Medicare covers and pays for pharmaceutical products. The legislation expanded Medicare coverage for drug purchases by the elderly and introduced a new reimbursement methodology based on average sales prices for drugs. In addition, this legislation authorized Medicare Part D prescription drug plans to use formularies where they can limit the number of drugs that will be covered in any therapeutic class. As a result of this legislation and the expansion of federal coverage of drug products, we expect that there will be additional

- 43 -

pressure to contain and reduce costs. These cost reduction initiatives and other provisions of this legislation could decrease the coverage and sales price that we receive for EGRIFTA^® or any other approved products and could seriously harm our business. While the MMA applies only to drug benefits for Medicare beneficiaries, private payors often follow Medicare coverage policy and payment limitations in setting their own reimbursement rates, and any reduction in reimbursement that results from the MMA may result in a similar reduction in payments from private payors.

More recently, in March 2010, U.S. President Obama signed into law the Health Care Reform Law, a sweeping law intended to broaden access to health insurance, reduce or constrain the growth of healthcare spending, enhance remedies against fraud and abuse, add new transparency requirements for healthcare and health insurance industries, impose new taxes and fees on the health industry and impose additional health policy reforms. Effective October 1, 2010, the Health Care Reform Law revised the definition of “average manufacturer price” for reporting purposes, which could increase the amount of Medicaid drug rebates to states. Further, beginning in 2011, the new law imposes a significant annual fee on companies that manufacture or import branded prescription drug products. We will not know the full effects of the Health Care Reform Law until applicable U.S. federal and state agencies issue regulations or guidance under the new law. Although it is too early to determine the effect of the Health Care Reform Law, the new law appears likely to continue to apply the pressure on pharmaceutical pricing. Pressure on pharmaceutical pricing may adversely affect the amount of our royalties in the United States.

3.3 RISKS RELATED TO OUR INTELLECTUAL PROPERTY

Our failure to protect our intellectual property may have a material adverse effect on our ability to develop and commercialize our products.

We will be able to protect our intellectual property rights from unauthorized use by third parties only to the extent that our intellectual property rights are covered and protected by valid and enforceable patents or are effectively maintained as trade secrets. We try to protect our intellectual property position by, among other things, filing patent applications related to our proprietary technologies, inventions and improvements that are important to the development of our business.

Because the patent position of pharmaceutical companies involves complex legal and factual questions, the issuance, scope, validity, and enforceability of patents cannot be predicted with certainty. Patents, if issued, may be challenged, invalidated or circumvented. If our patents are invalidated or found to be unenforceable, we would lose the ability to exclude others from making, using or selling the inventions claimed. Moreover, an issued patent does not guarantee us the right to use the patented technology or commercialize a product using that technology. Third parties may have blocking patents that could be used to prevent us from developing our product candidates, selling our products or commercializing our patented technology. Thus, patents that we own may not allow us to exploit the rights conferred by our intellectual property protection.

Our pending patent applications may not be issued or granted as patents. Even if issued, they may not be issued with claims of sufficient breadth to protect our product candidates and technologies or may not provide us with a competitive advantage against competitors with similar products or technologies. Furthermore, others may independently develop products or technologies similar to those that we have developed or may reverse engineer or discover our trade secrets through proper means. In addition, the laws of many countries do not protect intellectual property rights to the same extent as the laws of Canada, the United States and the European Patent Convention, and those countries may also lack adequate rules and procedures for defending intellectual property rights effectively.

- 44 -

Although we have received patents from the USPTO for the treatment of HIV-related lipodystrophy with tesamorelin, there can be no guarantee that, in the other countries where we filed patent applications for the treatment of HIV-related lipodystrophy, we will receive a patent or obtain granted claims of similar breadth to those granted by the USPTO.

We also rely on trade secrets, know-how and technology, which are not protected by patents, to maintain our competitive position. We try to protect this information by entering into confidentiality agreements with parties who have access to such confidential information, such as our current and prospective suppliers, distributors, manufacturers, commercial partners, employees and consultants. Any of these parties may breach the agreements and disclose confidential information to our competitors. It is possible that a competitor will make use of such information, and that our competitive position could be disadvantaged.

Enforcing a claim that a third party infringes on, has illegally obtained or is using an intellectual property right, including a trade secret or know-how, is expensive and time-consuming and the outcome is unpredictable. In addition, enforcing such a claim could divert management’s attention from our business. If any intellectual property right were to be infringed, disclosed to or independently developed by a competitor, our competitive position could be harmed. Any adverse outcome of such litigation or settlement of such a dispute could subject us to significant liabilities, could put one or more of our pending patent applications at risk of being invalidated or interpreted narrowly, could put one or more of our patents at risk of not issuing, or could facilitate the entry of generic products. Any such litigation could also divert our research, technical and management personnel from their normal responsibilities.

Our ability to defend ourselves against infringement by third parties of our intellectual property in the United States with respect to tesamorelin for the treatment of HIV-related lipodystrophy depends, in part, on our commercial partner’s decision to bring an action against such third party. Under the terms and conditions of our collaboration and licensing agreement with EMD Serono, EMD Serono has the first right to bring an action against a third party for infringing our patent rights with respect to tesamorelin for the treatment of HIV-related lipodystrophy. Any delay in pursuing such action or in advising us that it does not intend to pursue the matter could decrease sales, if any, of tesamorelin for the treatment of HIV-related lipodystrophy and adversely affect our revenues.

Furthermore, because of the substantial amount of discovery required in connection with intellectual property litigation, there is a risk that some of our confidential information could be compromised by disclosure during this type of litigation. For example, confidential information may be disclosed, inadvertently or as ordered by the court, in the form of documents or testimony in connection with discovery requests, depositions or trial testimony. This disclosure would provide our competitors with access to our proprietary information and may harm our competitive position.

Our commercial success depends, in part, on our ability not to infringe on third party patents and other intellectual property rights.

Our capacity to commercialize our product candidates, and more particularly tesamorelin, will depend, in part, upon our ability to avoid infringing third party patents and other third-party intellectual property rights. The biopharmaceutical and pharmaceutical industries have produced a multitude of patents and it is not always easy for participants, including us, to determine which patents cover various types of products, processes of manufacture or methods of use. The scope and breadth of patents is subject to interpretation by the courts and such interpretation may vary depending on the jurisdiction where the claim is filed and the court where such claim is litigated. The fact that we own patents for tesamorelin and for the treatment of HIV-related lipodystrophy does not guarantee that we are not infringing one or more third-party patents and there can be no guarantee that we will not infringe or

- 45 -

violate third-party patents and other third-party intellectual property rights in the United States or other jurisdictions.

Patent analysis for non-infringement is based in part on a review of publicly available databases. Although we review from time to time certain databases to conduct patent searches, we do not have access to all databases. It is also possible that we will not have reviewed some of the information contained in the databases or we found it to be irrelevant at the time we conducted the searches. In addition, because patents take years to issue, there may be currently pending applications that have not yet been published or that we are unaware of, which may issue later as patents. As a result, there can be no guarantee that we will not violate third-party patents.

Because of the difficulty in analyzing and interpreting patents, there can be no guarantee that a third party will not assert that we infringe such third-party’s patents or any of its other intellectual property rights. Under such circumstances, there is no guarantee that we would not become involved in litigation. Litigation with any third party, even if the allegations are without merit, is expensive, time-consuming and would divert management’s attention from the daily execution of our business plan. Litigation implies that a portion of our financial assets would be used to sustain the costs of litigation instead of being allocated to further the development of our business.

If we are involved in patent infringement litigation, we would need to prevail in demonstrating that our products do not infringe the asserted patent claims of the relevant patent, that the patent claims are invalid or that the patent is unenforceable. If we are found to infringe a third-party patent or other intellectual property right, we could be required to enter into royalty or licensing agreements on terms and conditions that may not be favourable to us, and/or pay damages, including up to treble damages in the United Sates (for example, if found liable of wilful infringement) and/or cease the development and commercialization of our product candidates. Even if we were able to obtain a license, the rights may be nonexclusive, which could result in our competitors gaining access to the same intellectual property and to compete with us.

We have not been served with any notice alleging that we infringe a third-party patent, but there may be issued patents that we are unaware of that our products may infringe, or patents that we believe we do not infringe but ultimately could be found to infringe. We are aware of third-party patents for the reduction of accumulation of fat tissue in HIV patients and, if a patent infringement suit was brought against us, we believe that we should not be found to infringe any valid claims of these patents. If we were to challenge the validity of a competitor’s issued United States patent in a United States court, we would need to overcome a statutory presumption of validity that attaches to every United States patent. This means that, in order to prevail, we would have to present clear and convincing evidence as to the invalidity of the patent’s claims. We cannot guarantee that a court would find in our favour on questions of infringement and validity. Any finding that we infringe or violate a third-party patent or other intellectual property right could materially adversely affect our business, financial condition and operating results.

3.4 OTHER RISKS RELATED TO OUR BUSINESS

We have a history of net losses and we may never achieve high profitability.

We have been reporting losses since our inception (except for the financial years ended November 30, 2010, 2001 and 2000) and, as at November 30, 2010, we had an accumulated deficit of $235,116,000. We do not expect to generate significant recurrent revenues sufficient to cover our overall activities in the immediate future. As a result of the foregoing, we will need to generate significant revenues to achieve profitability.

- 46 -

Our profitability will depend on, among other things, our commercial partners’ ability and willingness to successfully commercialize EGRIFTA^® and to obtain regulatory approval for the use of tesamorelin in the reduction of excess abdominal fat in HIV-infected patients with lipodystrophy in Europe, Latin America, Africa and the Middle East. However, there is no guarantee that our commercial partners will succeed in commercializing EGRIFTA^® or that our product candidates will ever receive approval for commercialization in any jurisdiction and, accordingly, we may never sustain profitability.

We rely on third-party service providers to conduct our preclinical studies and clinical trials and the failure by any of these third parties to comply with their obligations may delay the studies which could have an adverse effect on our development programs.

We have limited human resources to conduct preclinical studies and clinical trials and must rely on third-party service providers to conduct our studies and trials and carry out certain data gathering and analyses. If our third-party service providers become unavailable for any reason, including as a result of the failure to comply with the rules and regulations governing the conduct of preclinical studies and clinical trials, operational failures such as equipment failures or unplanned facility shutdowns, or damage from any event such as fire, flood, earthquake, business restructuring or insolvency or, if they fail to perform their contractual obligations pursuant to the terms of our agreements with them, such as failing to perform the testing, compute the data or complete the reports further to the testing, we may incur delays which may be significant in connection with the planned timing of our trials and studies which could adversely affect the timing of the development program of a product candidate or the filing of an application for marketing approval in a jurisdiction where we rely on third-party service providers to make such filing. In addition, where we rely on such third-party service provider to help in answering any question raised by a regulatory agency during its review of one of our files, the unavailability of such third-party service provider may adversely affect the timing of the review of an application and, could ultimately delay the approval. If the damages to any of our third-party service providers are material, or, for any reason, such providers do not operate in compliance with GLP or are unable or refuse to perform their contractual obligations, we would need to find alternative third-party service providers.

If we needed to change or select new third-party service providers, the planned working schedule related to preclinical studies and/or clinical trials could be delayed since the number of competent and reliable third-party service providers of preclinical and clinical work in compliance with GLP is limited. In addition, if we needed to change or select new third-party service providers to carry out work in response to a regulatory agency review of one of our applications, there may be delays in responding to such regulatory agency which, in turn, may lead to delays in commercializing a product candidate.

Any selection of new third-party service providers to carry out work related to preclinical studies and clinical trials would be time-consuming and would result in additional delays in receiving data, analysis and reports from such third-party service providers which, in turn, would delay the filing of any new drug application with regulatory agencies for the purposes of obtaining regulatory approval to commercialize our product candidates. Furthermore, such delays could increase our expenditures to develop a product candidate and materially adversely affect our financial condition and operating results.

The conduct of clinical trials requires the enrolment of patients and difficulties in enrolling patients could delay the conduct of our clinical trials or result in their non-completion.

The conduct of clinical trials requires the enrolment of patients. We may have difficulties enrolling patients for the conduct of our future clinical trials as a result of design protocol, the size of the patient population, the eligibility criteria to participate in the clinical trials, the availability of competing therapies, the patient referral practices of physicians and the availability of clinical trial sites. Difficulty

- 47 -

in enrolling patients for our clinical trials could result in the cancellation of clinical trials or delays in completing them. Once patients are enrolled in a clinical trial, the occurrence of any adverse drug effects or side effects observed during the trial could result in the clinical trial being cancelled. Any of these events would have material adverse consequences on the timely development of our product candidates, the filing of an NDA, or its equivalent, with regulatory agencies and the commercialization of such product candidates.

We may require additional funding and may not be able to raise the capital necessary to fund all or part of our capital requirements, including to continue and complete the research and development of our product candidates and their commercialization.

We do not generate significant recurrent revenues and may need financing in order to fund all or part of our capital requirements to sustain our growth, to continue research and development of new product candidates, to conduct clinical programs, to develop our marketing and commercial capabilities and to meet our compliance obligations with various rules and regulations to which we are subject. In the past, we have been financed through public equity offerings in Canada and private placements of our equity securities and we may need to seek additional equity offerings to raise capital, the size of which cannot be predicted. However, the market conditions or our business performance may prevent us from having access to the public market in the future at the times or in the amounts necessary. Therefore, there can be no guarantee that we will be able to continue to raise additional equity capital by way of public or private equity offerings in the future. In such a case, we would have to use other means of financing, such as issuing debt instruments or entering into private financing or credit agreements, the terms and conditions of which may not be favourable to us. If adequate funding is not available to us, we may be required to delay, reduce, or eliminate our research and development of new product candidates, our clinical trials or our marketing and commercialization efforts to launch and distribute new products, curtail significant portions of our product development programs that are designed to identify new product candidates and sell or assign rights to our technologies, products or product candidates. In addition, the issuance and sale of substantial amounts of equity, or other securities, or the perception that such issuances and sales may occur could adversely affect the market price of our common shares.

If product liability lawsuits are brought against us, they could result in costly and time-consuming litigation and significant liabilities.

Despite all reasonable efforts to ensure the safety of EGRIFTA^® and our other product candidates, it is possible that we or our commercial partners will sell products which are defective, to which patients react in an unexpected manner, or which are alleged to have side effects. The manufacture and sale of such products may expose us to potential liability, and the industries in which our products are likely to be sold have been subject to significant product liability litigation. Any claims, with or without merit, could result in costly litigation, reduced sales, significant liabilities and diversion of our management’s time and attention and could have a material adverse effect on our financial condition, business and results of operations.

If a product liability claim is brought against us, we may be required to pay legal and other expenses to defend the claim and, if the claim is successful, damage awards may be substantial and/or may not be covered, in whole or in part, by our insurance. We may not have sufficient capital resources to pay a judgment, in which case our creditors could levy against our assets. We may also be obligated to indemnify our commercial partners and make payments to other parties with respect to product liability damages and claims. Defending any product liability claims, or indemnifying others against those claims, could require us to expend significant financial and managerial resources.

- 48 -

The development and commercialization of our drugs could expose us to liability claims which could exceed our insurance coverage.

A risk of product liability claims is inherent in the development and commercialization of human therapeutic products. Product liability insurance is very expensive and offers limited protection. A product liability claim against us could potentially be greater than the available coverage and, therefore, have a material adverse effect upon us and our financial condition. Furthermore, a product liability claim could tarnish our reputation, whether or not such claims are covered by insurance or are with or without merit.

We depend on our key personnel to research, develop and bring new products to the market and the loss of key personnel or the inability to attract highly qualified individuals could have a material adverse effect on our business and growth potential.

The operation of our business requires qualified scientific and management personnel. The loss of scientific personnel or members of management could have a material adverse effect on our business. In addition, our growth is and will continue to be dependent, in part, on our ability to hire and retain the employment of qualified personnel. There can be no guarantee that we will be able to continue to retain our current employees or will be able to attract qualified personnel to achieve our business plan.

We may be unable to identify and complete in-licensing or acquisitions. In-licensing or acquisitions could divert management’s attention and financial resources, may negatively affect our operating results and could cause significant dilution to our shareholders.

In the future, we may engage in selective in-licensing or acquisitions of products or businesses that we believe are complementary to our products or business. There is a risk that we will not be able to identify suitable in-licensing or acquisition candidates available for sale at reasonable prices, complete any in-licensing or acquisition, or successfully integrate any in-licensed or acquired product or business into our operations. We are likely to face competition for in-licensing or acquisition candidates from other parties including those that have substantially greater available resources. In-licensing or acquisitions may involve a number of other risks, including:

	•		diversion of management’s attention;

	•		disruption to our ongoing business;

	•		failure to retain key acquired personnel;

	•		difficulties in integrating acquired operations, technologies, products or personnel;

	•		unanticipated expenses, events or circumstances;

	•		assumption of disclosed and undisclosed liabilities;

	•		inappropriate valuation of the acquired in-process research and development, or the entire acquired business; and

	•		difficulties in maintaining customer relations.

If we do not successfully address these risks or any other problems encountered in connection with an acquisition, the acquisition could have a material adverse effect on our business, results of operations and financial condition. Inherited liabilities of or other issues with an acquired business

- 49 -

could have a material adverse effect on our performance or our business as a whole. In addition, if we proceed with an acquisition, our available cash may be used to complete the transaction, diminishing our liquidity and capital resources, or shares may be issued which could cause significant dilution to our existing shareholders.

We may not achieve our publicly announced milestones on time.

From time to time, we publicly announce the timing of certain events to occur. These statements are forward-looking and are based on the best estimate of management at the time relating to the occurrence of such events. However, the actual timing of such events may differ from what has been publicly disclosed. Events such as completion of a clinical program, discovery of a new product candidate, filing of an application to obtain regulatory approval, beginning of commercialization of our products or announcement of additional clinical programs for a product candidate may vary from what is publicly disclosed. These variations may occur as a result of a series of events, including the nature of the results obtained during a clinical trial or during a research phase, problems with a supplier or a commercial partner or any other event having the effect of delaying the publicly announced timeline. We undertake no obligation to update or revise any forward-looking statements, whether as a result of new information, future events or otherwise, except as otherwise required by law. Any variation in the timing of certain events having the effect of postponing such events could have an adverse material effect on our business plan, financial condition or operating results.

The outcome of scientific research is uncertain and our failure to discover new compounds could slow down the growth of our portfolio of products.

We conduct research activities in order to increase our portfolio of product candidates. The outcome of scientific research is uncertain and may prove unsuccessful and, therefore, may not lead to the discovery of new molecules and progression of existing compounds to an advanced development stage. Our inability to develop new compounds or to further develop the existing ones could slow down the growth of our portfolio of products.

3.5 RISKS RELATED TO OUR COMMON SHARES

Our share price has been volatile, and an investment in our common shares could suffer a decline in value.

Since our initial public offering in Canada, our valuation and share price have had no meaningful relationship to current or historical financial results, asset values, book value or many other criteria based on conventional measures of the value of common shares. The market price of our common shares will fluctuate due to various factors including the risk factors described herein and other circumstances beyond our control.

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

Our quarterly operating results may fluctuate significantly.

We expect our operating results to be subject to quarterly fluctuations. Our net loss and other operating results will be affected by numerous factors, including:

•

variations in the level of revenues and royalties received related to EGRIFTA^®;

- 50 -

	•		variations in the level of expenses related to our development programs;

	•		addition or termination of clinical trials;

	•		any intellectual property infringement lawsuit in which we may become involved;

	•		regulatory developments affecting our product candidates;

	•		our execution of any collaborative, licensing or similar arrangements, and the timing of payments we may make or receive under these arrangements; and

	•		the achievement and timing of milestone payments under our existing strategic partnership agreements.

If our quarterly operating results fall below the expectations of investors or securities analysts, the price of our common shares could decline substantially. Furthermore, any quarterly fluctuations in our operating results may, in turn, cause the price of our stock to fluctuate substantially.

We do not intend to pay dividends on our common shares and, consequently, your ability to achieve a return on your investment will depend on appreciation in the price of our common shares.

We have never declared or paid any cash dividend on our common shares and do not currently intend to do so for the foreseeable future. We currently anticipate that we will retain future earnings for the development, operation and expansion of our business and do not anticipate declaring or paying any cash dividends for the foreseeable future. Therefore, the success of an investment in our common shares will depend upon any future appreciation in their value. There is no guarantee that our common shares will appreciate in value or even maintain the price at which our shareholders have purchased their shares. See “Dividend Policy”.

Our revenues and expenses may fluctuate significantly and any failure to meet financial expectations may disappoint securities analysts or investors and result in a decline in the price of our common shares.

Our revenues and expenses have fluctuated in the past and are likely to do so in the future. These fluctuations could cause our share price to decline. Some of the factors that could cause revenues and expenses to fluctuate include the following:

	•		the inability to complete product development in a timely manner that results in a failure or delay in receiving the required regulatory approvals or allowances to commercialize product candidates;

	•		the timing of regulatory submissions and approvals;

	•		the timing and willingness of any current or future collaborators to invest the resources necessary to commercialize the product candidates;

	•		the outcome of any litigation; changes in foreign currency fluctuations;

	•		the timing of achievement and the receipt of milestone payments from current or future third parties;

- 51 -

	•		failure to enter into new or the expiration or termination of current agreements with third parties; and

	•		failure to introduce the product candidates to the market in a manner that generates anticipated revenues.

We may be adversely affected by currency fluctuations.

A substantial portion of our revenue is earned in U.S. dollars, but a substantial portion of our operating expenses are incurred in Canadian dollars. Fluctuations in the exchange rate between the U.S. dollar and other currencies, such as the Canadian dollar, may have a material adverse effect on our business, financial condition and operating results. We do not currently engage in transactional hedging schemes but we do attempt to hedge or mitigate the risk of currency fluctuations by actively monitoring and managing our foreign currency holdings relative to our foreign currency expenses.

Our shareholder rights plan and certain Canadian laws could delay or deter a change of control.

Our shareholder rights plan entitles a rights holder, other than a person or group holding 20% or more of our common shares, to subscribe for our common shares at a discount of 50% to the market price at that time, subject to certain exceptions. See “Material Contracts-Shareholder Rights Plan Agreement”.

The Investment Canada Act (Canada) subjects an acquisition of control of a company by a non-Canadian to government review if the value of the assets as calculated pursuant to the legislation exceeds a threshold amount. A reviewable acquisition may not proceed unless the relevant minister is satisfied that the investment is likely to be a net benefit to Canada.

Any of the foregoing could prevent or delay a change of control and may deprive or limit strategic opportunities for our shareholders to sell their shares.

ITEM 6 SECURITIES OF THE COMPANY

6.1 AUTHORIZED SHARE CAPITAL

We are authorized to issue an unlimited number of common shares and an unlimited number of preferred shares issuable in series.

Subject to the priority rights of holders of preferred shares, holders of common shares are entitled to any dividend declared by the board of directors, to one vote per share at meetings of our shareholders and, in the event of our liquidation or dissolution, to participate in the distribution of the assets.

Preferred shares carry no voting rights. Preferred shares may be issued at any time in one or more series. Our articles of incorporation give our board of directors the power to fix the number of preferred shares and the consideration per share, as well as to determine the provisions attached to the preferred shares of each series (including dividends, redemption and conversion rights, if any). The shares of every series of preferred shares will have priority over all our other shares, including common shares, with respect to the payment of dividends and return of capital in the event of our liquidation or dissolution.

The common shares issued represent the total voting rights pertaining to our securities.

6.2 DIVIDEND POLICY

We have never declared or paid cash dividends on our common shares and do not anticipate paying any cash dividends on our common shares in the foreseeable future. We presently intend to retain future earnings, if any, to finance the expansion and growth of our business. Any future determination to pay dividends will be at the discretion of our board of directors and will depend on our financial condition, results of operations, capital requirements and other factors the board of directors deems relevant. In addition, the terms of any future debt or credit facility may preclude us from paying dividends.

ITEM 8 LEGAL PROCEEDINGS

On July 26, 2010, we received a motion for authorization to institute a class action lawsuit against us, our chairman and our former chief executive officer. This motion was filed in the Superior Court of Québec, district of Montreal. The applicant is seeking to initiate a class action suit and to certify and represent a class of persons who were shareholders at May 21, 2010 and who sold their common shares on May 25 or 26, 2010. This applicant alleges that we did not comply with our continuous disclosure obligations as a reporting issuer by failing to disclose certain alleged adverse effects relating to the administration of EGRIFTA^®. We are of the view that the allegations contained in the motion are entirely without merit and intend to take all appropriate actions to vigorously defend our position. The Motion has not yet been heard by the Superior Court of Québec and no date has been set for the hearing. We have subscribed for insurance covering our potential liability and the potential liability of our directors and officers in the performance of all their duties for us subject to a $200,000 deductible and standard terms, conditions and exclusions.

We are not otherwise currently subject to any material legal proceedings.

ITEM 9 MATERIAL CONTRACTS

Licensing Agreements. We have executed commercialization agreements with third parties for the exclusive distribution rights to EGRIFTA^® for the reduction of excess abdominal fact in HIV-infected patients with lipodystrophy for (i) the United States; (ii) Latin America, Africa and the Middle East; and (iii) Europe, Russia, South Korea, Taiwan, Thailand and certain central Asian countries. For a description of these agreements, see Item 2.5.

Supply Agreements. We have executed five supply agreements with Bachem, Draxis, Becton Dickinson, Hospira and ABAR. For a description of these agreements, see Item 2.7.

Shareholder Rights Plan Agreement. On February 10, 2010, we entered into a shareholder rights plan agreement, or Rights Plan. The Rights Plan entitles a holder of rights (other than the Acquiring Person, as defined below, or any affiliate or associate of an Acquiring Person or any person acting jointly or in concert with an Acquiring Person or any affiliate or associate of an Acquiring Person) to purchase to our common shares at a discount of 50% to the market price upon a person becoming an “Acquiring Person”, subject to certain exceptions and the terms and conditions set out in the Rights Plan. An “Acquiring Person” is defined in the Rights Plan as a beneficial owner of 20% or more of our common shares. The Rights Plan will expire at the close of our annual meeting of shareholders in 2013.

In order to implement the Rights Plan, we issued one right in respect of each common share outstanding as of 6:00 p.m. (Montreal time) on February 9, 2010, the “Effective Date”. One right will also be issued and attached to each subsequently issued common share. The rights will separate and trade separately from the common shares to which they are attached and will become exercisable after the “Separation Time”, as defined below:

The “Separation time” is the close of business on the tenth business day following the earliest of:

	(a)		the date of the first public announcement made by us or an Acquiring Person that a person has become an Acquiring Person;

	(b)		the date of the commencement of, or first public announcement of the intent of any Person to commence, a take-over bid (other than a Permitted Bid (as defined in the Rights Plan) or a Competing Permitted Bid (as defined in the Rights Plan)) by any person for our common shares;

	(c)		the date upon which a Permitted Bid or Competing Permitted Bid ceases to be such; or

	(d)		such later date as may be determined by the board of directors.

After the time at which a person becomes an Acquiring Person, and subject to the terms and conditions set out in the shareholder rights plan agreement, each right would, upon exercise, entitle a rights holder, other than the Acquiring Person and related persons, to purchase common shares at a 50% discount to the market price at the time.

Under the Rights Plan, a “Permitted Bid” is a bid made to all holders of the common shares and which is open for acceptance for not less than 60 days. If at the end of 60 days at least 50% of the outstanding common shares, other than those owned by the offeror and certain related parties, have been tendered, the offeror may take up and pay for the common shares but must extend the bid for a further 10 days to allow other shareholders to tender.
