PART I ITEM 1. DESCRIPTION OF BUSINESS. COMPANY SUMMARY We are a late-stage specialty pharmaceutical company applying our humanized lung surfactant technology to develop potential novel respiratory therapies and products. Surfactants are substances that are produced naturally in the lungs and are essential to the lungs' ability to absorb oxygen and to maintain proper airflow through the respiratory system. The absence or depletion of surfactants is involved in a number of respiratory diseases. Our humanized surfactant technology produces an engineered version of natural human lung surfactant and contains a peptide, sinapultide, that is designed to precisely mimic the essential human lung surfactant protein B (SP-B). We believe that our proprietary surfactant technology is the only surfactant technology presently available to potentially treat a broad range of respiratory diseases including Respiratory Distress Syndrome in adults and infants, asthma, chronic obstructive pulmonary disease (often referred to as COPD, which is a chronic condition of the lung that prevents enough oxygen from reaching the blood), Acute Lung Injury (often referred to as ALI), and upper airway disorders such as sinusitis (infection of the sinuses) and sleep apnea. Surfaxin(R), our lead product, is being developed initially for critical care patients with life-threatening respiratory disorders where there are few, if any, approved therapies. Surfaxin is currently in two Phase 3 clinical trials for Respiratory Distress Syndrome in premature infants, a Phase 3 clinical trial for Meconium Aspiration Syndrome in full-term infants, and a Phase 2 clinical trial for Acute Respiratory Distress Syndrome in adults. Aerosolized formulations of our humanized surfactant are presently being developed to potentially treat hospitalized patients suffering from severe acute asthma and Acute Lung Injury (ALI), typically requiring mechanical ventilation. In addition, we believe that scientific rationale supports the development of aerosolized formulations of our humanized surfactant to potentially treat chronic obstructive pulmonary disorder (COPD), sinusitis sleep apnea and otitis media (inner ear infection). We are presently developing a dedicated sales and marketing capability through a collaboration with Quintiles Transnational Corp. to commercialize Surfaxin in neonatal indications in the United States. We also have entered into a strategic alliance with Laboratorios del Dr. Esteve to commercialize Surfaxin in Europe and Latin America. We intend to establish additional strategic alliances, where appropriate, for the development and commercialization of our products in other indications and markets. SURFACTANT TECHNOLOGY Surfactants are protein and lipid (fat) compositions that are produced naturally in the lungs and are critical to all air-breathing mammals. They cover the entire alveolar surface, or air sacs, of the lungs and the terminal conducting airways which lead to the alveoli. Surfactants facilitate respiration by continually modifying the surface tension of the fluid normally present within the 1

alveoli that line the inside of the lungs. In the absence of sufficient surfactant or should the surfactant degrade, these air sacs tend to collapse, and, as a result, the lungs do not absorb sufficient oxygen. In addition to lowering aveolar surface-tension, surfactants play other important roles which include lowering the surface tension of the conducting airways and maintaining airflow and airway patency (keeping the airways open and expanded). Human surfactants include four known surfactant proteins, A, B, C and D. It has been established, through numerous studies, that surfactant protein B (SP-B) is essential for respiratory function. Presently, the FDA has approved surfactants as replacement therapy only for Respiratory Distress Syndrome in premature infants, a condition in which infants are born with an insufficient amount of their own natural surfactant. The most commonly used of these approved replacement surfactants are derived from pig and cow lungs. Though they are clinically effective, they have drawbacks and cannot readily be scaled or developed to treat broader populations for Respiratory Distress Syndrome in premature infants and other respiratory diseases. There is presently only one approved synthetic surfactant available, however, this product does not contain surfactant proteins, is not widely used, and it is not currently being actively marketed by its manufacturer. Animal-derived surfactant products are prepared using a chemical extraction process from minced cow and pig lung. Because of the animal-sourced materials and the chemical extraction processes, there is significant variation in production lots and, consequently, product quality specifications must be broad. In addition, the protein levels of these animal-derived surfactants are inherently lower than the protein levels of native human surfactant. The production costs of these animal-derived surfactants are high, relative to other analogous pharmaceutical products, generation of large quantities is severely limited, and these products cannot readily be reformulated for aerosol delivery to the lungs. Our humanized surfactant product candidates, including Surfaxin, are engineered versions of natural human lung surfactant and contain a humanized peptide, sinapultide. Sinapultide is a 21 amino acid protein-like substance that is designed to precisely mimic the essential human surfactant protein B (SP-B). We believe that our engineered humanized surfactant can be manufactured less expensively than the animal-derived surfactants, in sufficient quantities, in more exact and consistent pharmaceutical grade quality, and that it has no potential to cause adverse immunological responses in young and older adults, all important attributes for our products to potentially meet significant unmet medical needs. Our products also have the ability to be more precisely formulated, such as in the form of aerosolized liquids or dry powders, to address various medical indications. In addition, we believe that our engineered humanized surfactants might possess other pharmaceutical benefits not currently found with the animal surfactants such as longer shelf-life, reduced number of administrations to the patient's lungs, and elimination of the risk of animal-borne diseases including the brain-wasting bovine spongiform encephalopathy (commonly called "mad-cow disease"). Our humanized surfactant technology was invented at The Scripps Research Institute and was exclusively licensed to Johnson & Johnson which, together with its wholly-owned subsidiary, Ortho Pharmaceutical Corporation, developed it further. We acquired the exclusive worldwide sublicense to the technology in October 1996. 2

PRODUCTS - SURFACTANT BASED THERAPY FOR RESPIRATORY MEDICINE SURFAXIN(R) Surfaxin, our lead product, is the first humanized, protein B-based agent that mimics the surface-active properties of human surfactant. Surfaxin has been shown to remove inflammatory and infectious infiltrates from patients' lungs when used by our proprietary lavage (or "lung wash") and replenish the vital surfactant levels in the lungs. Currently, we are developing Surfaxin for the treatment of Respiratory Distress Syndrome in premature infants, Meconium Aspiration Syndrome in full-term infants, and Acute Respiratory Distress Syndrome in adults. Surfaxin is delivered in a liquid form and is injected through an endotracheal tube (a tube inserted into the infant's mouth and down the trachea) in premature infants, and as a proprietary lavage through a tube, called a bronchoscope, in full-term infants and adults. Respiratory Distress Syndrome in Premature Infants Respiratory Distress Syndrome is a condition in which premature infants are born with an insufficient amount of their own natural surfactant. Premature infants born prior to 32 weeks gestation have not fully developed a natural lung surfactant and therefore need treatment to sustain life. This condition often results in the need for mechanical ventilation. We are conducting a pivotal, multinational landmark Phase 3 trial treating up to 1,500 patients for the treatment of Respiratory Distress Syndrome in premature infants. This trial is designed to demonstrate the superiority of Surfaxin over the only commercially available synthetic surfactant and has a reference arm comparing Surfaxin to a bovine (cow) -derived surfactant. This pivotal trial is intended, if successful, to provide the basis for New Drug Applications with the FDA and other worldwide regulatory authorities. This pivotal trial is expected to be completed and data announced early in the fourth quarter of 2003. We are also conducting another multinational Phase 3 trial treating up to 500 patients for the treatment of Respiratory Distress Syndrome in premature infants. The primary purpose of this trial is to demonstrate the non-inferiority of Surfaxin over a certain porcine (pig) -derived surfactant. This trial is expected to be completed within the same timeframe as the pivotal Phase 3 trial. We are currently evaluating whether to conclude this trial early to conserve financial resources and reallocate clinical resources to our pivotal Phase 3 trial. Respiratory Distress Syndrome in premature infants affects approximately two million babies worldwide with approximately 270,000 cases occurring in the developed world. Due to limitations associated with the currently approved animal-derived products, only approximately 100,000 infants are estimated to be receiving surfactant therapy worldwide. The FDA has granted us Orphan Drug Designation for Surfaxin for this indication. Orphan drugs are pharmaceutical products that are intended to treat diseases affecting fewer than 200,000 patients in the United States. The Office of Orphan Product Development of the FDA grants certain advantages to the sponsors of orphan drugs including, but not limited to, seven 3

years of market exclusivity upon approval of the drug, certain tax incentives for clinical research and grants to fund testing of the drug. We are also seeking Orphan Product designation from the European Medicines Evaluation Agency (The European Union's regulatory approval agency that is similar to the FDA) for Surfaxin for the treatment of Respiratory Distress Syndrome in premature infants. Acute Respiratory Distress Syndrome in Adults Acute Respiratory Distress Syndrome (often referred to as ARDS) in adults is a life-threatening disorder for which no approved therapies exist anywhere in the world. It is characterized by an excess of fluid in the lungs and decreased oxygen levels in the patient. One prominent characteristic of this disorder is the destruction of surfactants naturally present in lung tissue. The conditions are caused by illnesses including pneumonia and septic shock (a toxic condition caused by infection) and events such as smoke inhalation, near drowning, industrial accidents and other traumas. We are presently conducting a Phase 2 open-label, controlled, multi-center clinical trial of Surfaxin for adults with Acute Respiratory Distress Syndrome. Up to 110 patients will receive high concentrations of Surfaxin via a proprietary lavage technique that administers the drug sequentially through a tube, called a bronchoscope. The procedure is intended to cleanse and remove inflammatory substances and debris from the lungs, while leaving amounts of Surfaxin behind to help re-establish the lungs' capacity to absorb oxygen. The objective is to restore functional surfactant levels and to allow critically ill patients to be removed from mechanical ventilation. In July 2002, we completed the first part of this trial, a dose escalation safety and tolerability study in 22 patients in four groups (of up to six patients per group). In consultation with the Independent Safety Review Committee, comprised of three prominent pulmonologists, that was assembled for this trial, we determined that the Part A portion of the trial procedure is generally safe and tolerable and that it was appropriate to proceed onto the larger safety and efficacy portion of the study. The last part of this Phase 2 trial, Part B, will evaluate safety and efficacy of Surfaxin in direct comparison to standard of care at approximately 40 centers in the United States. The primary endpoint of this part of the trial is to determine the incidence rate of patients being alive and off mechanical ventilation at the end of day 28 with one of the key secondary endpoints being mortality. Our contract manufacturer for drug product for this trial has experienced certain operational difficulties which have delayed the completion of this part of the trial. However, we expect that clinical drug supply will be available to allow us to complete this trial in the fourth quarter of 2003. See Item 1: "Manufacturing and Distribution - Third Party Suppliers." The current standard of care for Acute Respiratory Distress Syndrome includes placing patients on mechanical ventilators in intensive care units at a cost of approximately $8,500 per day, typically for an average of 21 to 28 days. There are estimated to be between 150,000 and 250,000 adults per year in the United States suffering from Acute Respiratory Distress Syndrome 4

with similar numbers afflicted in Europe. Because there are no approved treatments for these diseases, the mortality rate can range from 35% to 50%. The FDA has granted us Fast-Track Approval Status and Orphan Drug Designation for Surfaxin for the treatment of Acute Respiratory Distress Syndrome for adults. The European Medicines Evaluation Agency has granted us Orphan Product designation for Surfaxin for the treatment of Acute Lung Injury in adults (which in this circumstance encompasses Acute Respiratory Distress Syndrome). We were awarded a $1 million Fast-Track Small Business Innovative Research Grant by the National Institutes of Health to develop Surfaxin for the treatment of Acute Respiratory Distress Syndrome and Acute Lung Injury in adults, of which $307,000 is still to be received, subject to certain performance criteria. Meconium Aspiration Syndrome in Full-Term Infants Meconium Aspiration Syndrome is a condition in which full-term infants are born with meconium in their lungs that depletes the natural surfactant in their lungs. Meconium is a baby's first bowel movement in its mother's womb and when inhaled, Meconium Aspiration Syndrome can occur. Meconium Aspiration Syndrome can be life-threatening as a result of the failure of the lungs to absorb sufficient oxygen. This condition results in the need for mechanical ventilation. Surfaxin is being evaluated in a Phase 3 clinical trial for the treatment of Meconium Aspiration Syndrome in full-term infants. To our knowledge, Surfaxin is the only product being developed worldwide to treat this syndrome. The trial is designed for the enrollment of up to 200 infants at medical centers throughout the United States to compare Surfaxin lavage to the current standard of care. Enrollment is ongoing but has been slower than expected and completion is now anticipated for 2004. Given our belief in the importance of the pivotal Phase 3 trial for Respiratory Distress Syndrome in premature infants to our present development plan, resources have been reallocated from the Meconium Aspiration Syndrome program to the Respiratory Distress Syndrome program. We also have initiated a Phase 2 clinical trial for Surfaxin lavage in up to 60 full-term infants for use as a prophylactic or early treatment for patients who are at risk for Meconium Aspiration Syndrome but have not shown symptoms of compromised respiratory function. There are approximately 600,000 babies born each year that are at risk for Meconium Aspiration Syndrome, of which about 10% develop the condition. We believe an effective and affordable surfactant prophylactic therapy could significantly lower the risk to meconium-stained infants of chronic respiratory conditions and reduce the need for costly mechanical ventilation. There are presently no drug therapies approved for the treatment of Meconium Aspiration Syndrome in full-term infants. The FDA has granted us Fast-Track Approval Status and Orphan Drug Designation for Surfaxin for the treatment of Meconium Aspiration Syndrome in full-term infants. We have also received Orphan Product designation of Surfaxin as for the treatment of Meconium Aspiration Syndrome from the European Medicines Evaluation Agency. 5

OUR AEROSOLIZED HUMANIZED SURFACTANTS FOR RESPIRATORY THERAPY Many respiratory diseases are associated with an inflammatory event that causes surfactant dysfunction and a loss of patency of the conducting airways. Scientific data supports that the therapeutic use of surfactants in aerosol form has the ability to reestablish airway patency, improve pulmonary mechanics, and act as an anti-inflammatory. Surfactant normally prevents moisture from accumulating in the airways' most narrow sections and in this way maintains patency of the conducting airways. However, use of currently available animal-derived surfactants is not considered feasible for aerosolization and because of their potential to cause an adverse immunological response such products may exacerbate the inflammatory event associated with such diseases. We are currently developing aerosolized formulations of our humanized surfactant to potentially treat patients who could benefit from surfactant-based therapy to improve lung function and maintain proper airflow through the respiratory system. Our aerosol development program is initially focused on surfactant-based therapy for hospitalized patients suffering from severe acute asthma or Acute Lung Injury (ALI), hopefully avoiding or reducing the need for mechanical ventilation. In addition, we believe that scientific rationale supports the development of aerosolized formulations of our humanized surfactant to potentially treat COPD, sinusitis, sleep apnea and otitis media (inner ear infection). We are presently working with various aerosol devices towards achieving the following important development objectives: - -- Full retention of the surface-tension lowering properties of a functioning surfactant necessary to restore lung function and maintain patency of the conducting airways. - -- Full retention of the surfactant composition upon aerosolization. - -- Drug particle size suitable for deposition in the deep-lungs. - -- Delivery rates to achieve therapeutic dosages in a reasonable time period. - -- Reproducible aerosol output and minimal waste of surfactant dose. Our lead programs for surfactant-based therapy as an aerosol are: Asthma Asthma is a common disease characterized by sudden constriction and inflammation of the lungs. Constriction of the upper airway system is caused by a tightening of airway muscles, while inflammation is a swelling of the airways usually due to an allergic reaction due to an airborne irritant. Both of these events cause airways to narrow and may result in wheezing, shortness of breath and chest tightness. Several studies have shown that surfactant damage and dysfunction is a significant component of asthma -- airway obstruction occurs when there is a surfactant dysfunction in the airways of the deep lung of the type that develops during an asthma 6

attack. Surfactant replacement therapy has the potential to relieve the obstruction in the airways associated with asthma. According to information provided by the American Lung Association, asthma afflicts approximately 20.3 million people in the United States and its incidence rate is rising. Asthma is a chronic disease; prevalent in people of all ages and an estimated 12 million people have experienced an asthma attack within the past year. In the United States alone, there are roughly 1 million hospital outpatient visits, approximately 1.8 million emergency room visits, and 9.3 million physician visits each year due to asthma. Asthma ranks within the top 10 prevalent activity-limiting health conditions costing $14 billion in United States healthcare costs annually. Asthma may require life-long therapy to prevent or treat episodes. Ten percent of patients are considered severe asthmatics and require moderate to high doses of drugs. Currently available medications to treat and control asthma include inhaled and oral steroids and bronchodilators. Bronchodilators cannot be used to control severe episodes or chronic, severe asthma. Steroidal medications are used to address these conditions, however, steroids can cause serious side effects when used for prolonged periods. As a result, steroid use is typically limited to severe asthmatic episodes and chronic, severe asthma. Several small scientific studies report that patients suffering from a severe, acute asthma attack were relieved when they inhaled aerosolized surfactant. We believe that supplying surfactant as an aerosol spray would be a simple and gentle way of relieving airway obstruction and thereby augmenting currently available conventional asthma therapies to lead to a more rapid improvement in symptoms. Acute Lung Injury Acute Lung Injury is associated with conditions that either directly or indirectly injure the air sacs of the lung, the alveoli. Acute Lung Injury is a syndrome of inflammation and increased permeability of the lungs with an associated breakdown of the lungs' surfactant layer. The most serious manifestation of Acute Lung Injury is Acute Respiratory Distress Syndrome. Among the causes of Acute Lung Injury are complications typically associated with certain major surgeries, mechanical ventilator induced lung injury (often referred to as VILI), smoke inhalation, pneumonia, and sepsis. There is an estimated 1 million patients at risk in the United States for Acute Lung Injury annually and there are no currently-approved therapies. We believe that our proprietary humanized aerosol surfactant may be effective as a preventive measure for patients at risk for Acute Lung Injury. This prophylactic approach may result in fewer patients requiring costly intensive care therapy and shorter periods of therapy - thus offering cost savings in the hospital setting. Collaborative Research Arrangements We have a collaborative relationship with Aerogen, Inc., to evaluate its aerosol generator technology for the delivery of our proprietary aerosolized surfactants to prevent and treat 7

respiratory diseases in the hospital. Aerogen's technology is designed to be used with a hospital ventilator system or in an ambulatory manner to treat patients anywhere in the hospital, including the emergency room, the hospital floor and during patient transport. We also have a collaborative research arrangement for our aerosolized surfactant programs with CollaGenex Pharmaceuticals, Inc. to evaluate the combination of their protease inhibitor technologies with our proprietary aerosolized surfactant technology for the development of novel respiratory disease therapeutics. Through the collaboration we anticipate developing and assessing aerosol formulations of humanized lung surfactant and protease inhibitors as potential treatments for diseases such as Acute Lung Injury and chronic obstructive lung disease (COPD). AEROSOLIZED HUMANIZED SURFACTANTS FOR PULMONARY DRUG DELIVERY We are evaluating formulations of our engineered humanized surfactants as novel pulmonary drug delivery vehicles with the potential to deliver other pharmaceutical products to the lungs so that such products can exert their pharmacological effects locally or systemically. Existing drug delivery technology has effectively addressed the development of delivery devices, drug storage systems and compatible drug formulations. However, a significant unmet need in pulmonary drug delivery is to provide better performance once a drug is deposited in the lungs. An aerosol version of our humanized lung surfactant, with its ability to penetrate and spread in an even manner throughout the lungs, has the potential to more efficiently deliver drugs via or within the respiratory tract. These drugs include antibiotics, pulmonary vasodilators that lower blood pressure in the lung arteries, elastase inhibitors (drugs that are anti-inflammatory by inhibiting a potentially destructive enzyme that comes from certain types of white blood cells), bronchodilators (drugs that mitigate constriction of small airways), steroids and proteins. STRATEGIC ALLIANCES LABORATORIOS DEL DR. ESTEVE, S.A. In March 2002, we significantly expanded our existing relationship with Laboratorios del Dr. Esteve by entering into a new collaboration arrangement with Esteve. This new collaboration expands the territory covered by the original agreements to include all of Europe and Latin America. In connection with this new Esteve collaboration, Esteve purchased 821,862 shares of our common stock at $4.867 per share for $4.0 million in cash and paid us a non-refundable licensing fee of $500,000. Esteve agreed to provide certain commercialization services in the expanded territory for Surfaxin for the treatment of Respiratory Distress Syndrome in premature infants, Meconium Aspiration Syndrome in full-term infants and Acute Lung Injury/Acute Respiratory Distress Syndrome in adult patients. We have agreed to an exclusive supply agreement which provides that Esteve will purchase from us all of its Surfaxin drug product requirements at an established transfer price based on sales of Surfaxin by Esteve and/or its sublicensee(s). Esteve has also agreed to sponsor certain clinical 8

trial costs related to obtaining European Medicines Evaluation Agency approval for commercialization of Surfaxin in Europe for the Acute Lung Injury/Acute Respiratory Distress Syndrome indications. Esteve also agreed to make certain milestone payments upon the attainment of European Medicines Evaluation Agency marketing regulatory approval of Surfaxin for sale in Europe for the foregoing indications. QUINTILES TRANSNATIONAL CORP., AND PHARMABIO DEVELOPMENT, INC. In December 2001, we entered into a collaboration arrangement with Quintiles, and its affiliate, PharmaBio Development, Inc., to provide certain commercialization services in the United States for Surfaxin for the treatment of Respiratory Distress Syndrome in premature infants and Meconium Aspiration Syndrome in full-term infants. We issued to PharmaBio 791,905 shares of our common stock and warrants to purchase approximately 677,143 shares of our common stock for aggregate net proceeds of approximately $2.7 million. Quintiles will hire and train a dedicated United States sales force that will be branded in the market as ours. PharmaBio has agreed to fund up to $70 million of the sales force costs and other sales and marketing costs for Surfaxin for seven years of commercialization of Surfaxin in the United States. Additionally, the collaboration allows for the specialty sales force to become ours at the end of the seven year term, with an option to acquire it sooner. Under the collaboration, we will receive 100% of the revenues from sales of Surfaxin and have agreed to pay PharmaBio a commission on net sales in the United States of Surfaxin for the treatment of Respiratory Distress Syndrome in premature infants and Meconium Aspiration Syndrome in full-term infants and all "off-label" uses for 10 years following first launch of the product in the United States. The collaboration allows us to retain product ownership and to have sales and marketing expertise in place for the commercialization of Surfaxin, if approved. PharmaBio also extended to us a secured revolving credit facility of up to $8.5 million to $10 million to fund pre-marketing activities associated with the launch of Surfaxin in the United States as we achieve certain milestones. We are obligated to use a significant portion of the funds borrowed under the credit facility for pre-launch marketing services to be provided by Quintiles. Principal amounts owed by us under the credit facility may be repaid out of the proceeds of milestone payments to be paid to us by PharmaBio upon the achievement of certain corporate milestones. To the extent availability under the credit facility is increased to greater than $8.5 million, for each such $1 million dollar increase, the amount of shares of common stock issuable pursuant to the warrants will be increased by approximately 38,000 shares.

LICENSING ARRANGEMENTS; PATENTS AND PROPRIETARY RIGHTS PATENTS AND PROPRIETARY RIGHTS Johnson & Johnson and The Scripps Research Institute Our humanized surfactant platform technology, including Surfaxin, is based on the proprietary peptide, sinapultide, (a 21 amino acid protein-like substance that precisely mimics the essential human lung protein SP-B). This technology was invented at The Scripps Research Institute and was exclusively licensed to, and further developed by, Johnson & Johnson, and its wholly owned subsidiary, Ortho Pharmaceutical. We have received an exclusive, worldwide sublicense from Johnson & Johnson and Scripps for, and have rights to, a series of over 30 patents and patent filings (worldwide) which are important, either individually or collectively, to our strategy of commercializing our humanized surfactant technology for the diagnosis, prevention and treatment of disease. The sublicense gives us the rights to such patents for the life of the patents. Patents covering our proprietary humanized surfactant technology that have been issued or are pending worldwide include composition of matter, formulation, manufacturing and uses, including the pulmonary lavage, or "lung wash" techniques. Our most significant patent rights principally consist of five issued United States patents: U.S. Patent No. 5,407,914; U.S. Patent No. 5,260,273; U.S. Patent No. 5,164,369; U.S. Patent No.5,789,381; and U.S. Patent No. 6,013,619 (along with corresponding issued and pending foreign patents). These patents relate to engineered humanized pulmonary surfactants (including Surfaxin), certain related peptides (amino acid protein-like substances) and compositions, methods of treating respiratory distress syndromes with these surfactants and compositions, and our proprietary pulmonary lavage method of treating respiratory distress syndrome with these surfactants. We also have certain pending United States and foreign patent applications that relate to methods of manufacturing certain peptides which may be used in the manufacture of Surfaxin and other aspects of our humanized surfactant technology. In October 2002, we were issued European Patent No. 59006 which covers claims directed to compositions that contain our proprietary peptide, sinapultide, and related peptides for use as a therapeutic surfactant for treating respiratory distress syndrome and related conditions. We also have an issued European Patent, No. 0350506, covering certain other surfactant peptides. U.S. Patent No. 6,013,619 was issued to Scripps and licensed to us and covers all known engineered (including Surfaxin), animal- or human-derived surfactants for use in any form of pulmonary lavage for respiratory distress syndromes. Our proprietary pulmonary lavage techniques (using surfactant) include lavage via a bronchoscope in adults as well as direct pulmonary lung lavage via an endotracheal tube in newborn babies with Meconium Aspiration Syndrome. Scientific rationale supports that our proprietary lavage technique may provide a clinical benefit to the treatment of Acute Lung Injury/Acute Respiratory Distress Syndrome in adults and Meconium Aspiration Syndrome in full-term infants by decreasing the amount of infectious and inflammatory debris in the lungs, restoring the air sacs to a more normal state and possibly resulting in patients getting off mechanical ventilation sooner. 10

Such patents, which include relevant European patents, expire on various dates beginning in 2009 and ending 2017 or, in some cases, possibly later. THE SCRIPPS RESEARCH INSTITUTE RESEARCH AGREEMENT We are parties with Scripps to a research funding and option agreement which expires in February 2005, subject to termination by us at any time with 90 days prior notice. Pursuant to this agreement, we fund a portion of Scripps' research efforts and are entitled to an option to acquire an exclusive worldwide license to the technology developed from the research program during the term of the agreement. Scripps owns all of the technology that it developed pursuant to work performed under the agreement. To the extent we do not exercise our option, we have the right to receive 50% of the net royalty income received by Scripps for inventions that we jointly develop under the agreement. See Item 7: "Management's Discussion and Analysis - Risks Related to Our Business": " - If we cannot protect our intellectual property, other companies could use our technology in competitive products. If we infringe the intellectual property rights of others, other companies could prevent us from developing or marketing our products"; " - Even if we obtain patents to protect our products, those patents may not be sufficiently broad and others could compete with us"; " - Intellectual property rights of third parties could limit our ability to market our products"; and " - If we cannot meet requirements under our license agreements, we could lose the rights to our products." MANUFACTURING AND DISTRIBUTION - THIRD PARTY SUPPLIERS Manufacturing Our humanized surfactant product candidates must be manufactured in a sterile environment and in compliance with good manufacturing practice requirements (GMPs) set by the FDA and other relevant worldwide regulatory authorities. Our humanized surfactant product candidates are manufactured through the combination of a synthetically made peptide, sinapultide, (designed to precisely mimic the essential human lung surfactant protein SP-B) which is provided by BACHEM California, Inc., and PolyPeptides Laboratories, Inc., and certain other active ingredients, including certain lipids, that are provided by other suppliers such as Genzyme Pharmaceuticals, a division of the Genzyme Corporation, and Avanti Polar Lipids. Our humanized surfactant drug product, including Surfaxin, is manufactured using our own specialized equipment, using the ingredients discussed above, under the direction and supervision of our manufacturing and quality control personnel. Currently, our drug product is manufactured at the sterile facilities of a contract manufacturer, Akorn, Inc., which is presently the only manufacturing facility that we have validated to produce appropriate clinical grade material of our humanized surfactant drug substance, including Surfaxin. 11

Our present manufacturing capabilities should allow sufficient commercial production of Surfaxin, if approved, to supply the present worldwide demand for Respiratory Distress Syndrome for premature infants and Meconium Aspiration Syndrome for full-term infants. We expect these capabilities to allow us to provide adequate supply of Surfaxin for our planned clinical trials for Acute Respiratory Distress Syndrome in adults. We are presently investing in and evaluating alternative contract manufacturers in order to provide backup for the production of our humanized surfactant drug product and to scale up to meet clinical and commercial needs as they expand. We will rely on outside manufacturers for production of our products after marketing approval. Should the proper financial and other resources be available, our manufacturing process for our humanized surfactant drug product allows us, unlike that for the currently-approved, animal-derived products, to scale-up production of our humanized surfactant drug product, including Surfaxin. By scaling up our production, we should be able to produce sufficient drug products to potentially treat diseases with larger patient populations, such as Acute Respiratory Disease Syndrome in adults, asthma, Acute Lung Injury, COPD, and other broader respiratory diseases and upper airway disorders. In December 2002, we reported that Akorn was experiencing certain operating difficulties in a sterile production room primarily used for the filling of sterile pharmaceutical products such as our drug product. Although Akorn's difficulties with this sterile filling room were not directly related to the actual production of our drug product, a delay in the supply of Surfaxin for Part B of our ongoing Phase 2 clinical trial for Acute Respiratory Distress Syndrome in adults occurred. On February 18, 2003, Akorn notified us that their sterile filling room had returned to operational status. We have initiated activities at Akorn and expect to recommence manufacture of Surfaxin in a timeframe that allows us to complete our Phase 2 clinical trial for Acute Respiratory Disease Syndrome in adults in the fourth quarter of 2003. The difficulties experienced by Akorn are not expected to have an effect on our ongoing Phase 3 trials for Surfaxin for Respiratory Distress Syndrome in premature infants or our longer range clinical development plans for our humanized surfactant drug candidates. Manufacturing or quality control problems could occur at Akorn or our other contract manufacturers, if any, and cause product production and shipment delays or a situation where the contractor may not be able to maintain compliance with the FDA's current GMP requirements necessary to continue manufacturing our drug substance. If any such suppliers or manufacturers of our products fail to comply with GMP requirements or other FDA and comparable foreign regulatory requirements, it could adversely affect our clinical research activities and our ability to market and develop our products. See Item 7: "Management's Discussion and Analysis - Risks Related to Our Business": " - If the parties we depend on for manufacturing our pharmaceutical products do not timely supply these products, it may delay or impair our ability to develop and market our products"; and " - In order to conduct our clinical trials we need adequate supplies of our drug substance and drug product and competitors drug product, which may not be readily available." 12

Distribution Our collaboration agreement with Quintiles to provide certain commercialization services in the United States for Surfaxin does not encompass distribution services. We are currently evaluating third party distribution capability in order to commercialize Surfaxin in the United States. Our collaboration with Esteve provides that Esteve has the responsibility for distribution throughout Europe and Latin America. See Item 7: "Management's Discussion and Analysis - Risks Related to Our Business-Our lack of marketing and sales experience could limit our ability to generate revenues from future product sales." COMPETITION We are engaged in highly competitive fields of pharmaceutical research. Competition from numerous existing companies and others entering the fields in which we operate is intense and expected to increase. We expect to compete with, among others, conventional pharmaceutical companies. Most of these companies have substantially greater research and development, manufacturing, marketing, financial, technological personnel and managerial resources than we do. Acquisitions of competing companies by large pharmaceutical or health care companies could further enhance such competitors' financial, marketing and other resources. Moreover, competitors that are able to complete clinical trials, obtain required regulatory approvals and commence commercial sales of their products before we do may enjoy a significant competitive advantage over us. There are also existing therapies that may compete with the products we are developing. See Item 7: "Management's Discussion and Analysis - Risks Related to Our Business - Our industry is highly competitive and we have less capital and resources than many of our competitors, which may give them an advantage in developing and marketing products similar to ours or make our products obsolete." Presently, the FDA has approved surfactants as replacement therapy only for Respiratory Distress Syndrome in premature infants, a condition in which infants are born with an insufficient amount of their own natural surfactant. The most commonly used of these approved replacement surfactants are derived from a chemical extraction process of pig and cow lungs. Curosurf(R) is a porcine lung extract that is marketed in Europe by Chiesi Farmaceutici S.p.A., and in the United States by Dey Laboratories, Inc. Survanta(R), marketed by the Ross division of Abbott Laboratories, Inc., is derived from minced cow lung that contains the cow version of surfactant protein B. Forest Laboratories, Inc., markets its calf lung surfactant extract, Infasurf(R), in the United States. There is presently only one approved synthetic surfactant available, Exosurf(R), marketed by GlaxoSmithKline, plc. However, this product does not contain any surfactant proteins, is not widely used, and its active marketing recently has been discontinued by its manufacturer. Our ongoing pivotal, landmark Phase 3 clinical trial for the treatment of Respiratory Distress Syndrome in premature infants is designed as a prophylaxis, superiority trial comparing our Surfaxin to Exosurf(TM). 13

With respect to the development of lung surfactants for the treatment of other respiratory diseases and upper airway disorders, with the exception of one porcine-derived surfactant drug candidate under development by Leo Pharma A/S in Denmark, we are not aware of any other lung surfactant currently under development. There are no drugs currently approved that are specifically indicated for the treatment of Acute Respiratory Distress Syndrome in adults or Meconium Aspiration Syndrome in full-term infants. Current therapy consists of general supportive care and mechanical ventilation. There are a significant number of other potential therapies in development for the treatment of Acute Respiratory Distress Syndrome in adults that are not surfactant related. Any of these various drugs or devices could significantly impact the commercial opportunity for Surfaxin. Our humanized surfactant product candidates, including Surfaxin, are engineered versions of natural human lung surfactant and contain a humanized peptide, sinapultide (a 21 amino acid protein-like substance), that is designed to precisely mimic the essential human surfactant protein B (SP-B). We believe that our engineered humanized surfactant can be manufactured less expensively than the animal-derived surfactants, in sufficient quantities, in exact and consistent pharmaceutical grade quality, and has no potential to cause adverse immunological responses in young and older adults, all important attributes to potentially meet significant unmet medical needs. Our products also have the ability to be more precisely formulated, such as in the form of aerosolized liquids or dry powders to address various medical indications. In addition, we believe that our engineered humanized surfactants might possess other pharmaceutical benefits not currently found with the animal surfactants such as longer shelf-life, reduced number of administrations to the patient's lungs, and elimination of the risk of animal-borne diseases including the brain-wasting bovine spongiform encephalopathy (commonly called "mad-cow disease"). GOVERNMENT REGULATION The testing, manufacture, distribution, advertising and marketing of drug products are subject to extensive regulation by federal, state and local governmental authorities in the United States, including the FDA, and by similar agencies in other countries. Any product that we develop must receive all relevant regulatory approvals or clearances before it may be marketed in a particular country. The regulatory process, which includes preclinical studies and clinical trials of each pharmaceutical compound to establish its safety and efficacy and confirmation by the FDA that good laboratory, clinical and manufacturing practices were maintained during testing and manufacturing, can take many years, requires the expenditure of substantial resources and gives larger companies with greater financial resources a competitive advantage over us. Delays or terminations of clinical trials we undertake would likely impair our development of product candidates. Delays or terminations could result from a number of factors, including stringent enrollment criteria, slow rate of enrollment, size of patient population, having to compete with other clinical trials for eligible patients, geographical considerations and others. 14

The FDA review process can be lengthy and unpredictable, and we may encounter delays or rejections of our applications when submitted. If questions arise during the FDA review process, approval may take a significantly longer period of time. Generally, in order to gain FDA approval, we first must conduct preclinical studies in a laboratory and in animal models to obtain preliminary information on a compound's efficacy and to identify any safety problems. The results of these studies are submitted as part of an IND (Investigational New Drug) application that the FDA must review before human clinical trials of an investigational drug can start. Clinical trials are normally done in three sequential phases and generally take two to five years or longer to complete. Phase 1 consists of testing the drug product in a small number of humans, normally healthy volunteers, to determine preliminary safety and tolerable dose range. Phase 2 usually involves studies in a limited patient population to evaluate the effectiveness of the drug product in humans having the disease or medical condition for which the product is indicated, determine dosage tolerance and optimal dosage and identify possible common adverse effects and safety risks. Phase 3 consists of additional controlled testing at multiple clinical sites to establish clinical safety and effectiveness in an expanded patient population of geographically dispersed test sites to evaluate the overall benefit-risk relationship for administering the product and to provide an adequate basis for product labeling. Phase 4 clinical trials are conducted after approval to gain additional experience from the treatment of patients in the intended therapeutic indication. After completion of clinical trials of a new drug product, FDA and foreign regulatory authority marketing approval must be obtained. A New Drug Application submitted to the FDA generally takes one to three years to obtain approval. If questions arise during the FDA review process, approval may take a significantly longer period of time. The testing and approval processes require substantial time and effort and we may not receive approval on a timely basis, if at all. Even if regulatory clearances are obtained, a marketed product is subject to continual review, and later discovery of previously unknown problems or failure to comply with the applicable regulatory requirements may result in restrictions on the marketing of a product or withdrawal of the product from the market as well as possible civil or criminal sanctions. For marketing outside the United States, we also will be subject to foreign regulatory requirements governing human clinical trials and marketing approval for pharmaceutical products. The requirements governing the conduct of clinical trials, product licensing, pricing and reimbursement vary widely from country to country. None of our products under development have been approved for marketing in the United States or elsewhere. We may not be able to obtain regulatory approval for any such products under development. Failure to obtain requisite governmental approvals or failure to obtain approvals of the scope requested will delay or preclude us, or our licensees or marketing partners, from marketing our products, or limit the commercial use of our products, and thereby would have a material adverse effect on our business, financial condition and results of operations. See Item 7: "Management's Discussion and Analysis - Risks Related to Our Business": " - Our technology platform is based solely on our proprietary humanized, engineered surfactant technology and only our lead product candidate, Surfaxin, has been subject to clinical studies. Our ongoing Phase 3 clinical trials for Surfaxin for the treatment of Respiratory Distress Syndrome in premature infants may be delayed, or fail, which will harm our business"; and " - The clinical trial and regulatory approval process for our products is expensive and time consuming, and the outcome is uncertain." 15

The FDA has granted us Fast-Track Approval Status for the Acute Respiratory Distress Syndrome and Meconium Aspiration Syndrome indications. Fast-Track Approval Status facilitates the development and expedites the review of new drugs intended for treatment of life-threatening conditions for which there is presently no medical option or an unmet medical need by providing for the FDA's review of the New Drug Application for a drug granted such Fast Track Status within six months following filing. We have also received Orphan Drug Designation from the FDA's Office of Orphan Products Development of Surfaxin as a treatment for Respiratory Distress Syndrome in premature infants, Meconium Aspiration Syndrome in full-term infants, and Acute Respiratory Distress Syndrome in adults. We have also received designation of Surfaxin as an Orphan Product for Meconium Aspiration Syndrome and Acute Lung Injury (which, in this circumstance, encompasses Acute Respiratory Distress Syndrome) from the European Medicines Evaluation Agency (EMEA). EMPLOYEES We have approximately 65 full-time employees, primarily employed in the United States, Europe and Latin America. Our future success depends in significant part upon the continued service of our key scientific personnel and executive officers and our continuing ability to attract and retain highly qualified scientific and managerial personnel. It is a competitive market for such personnel and we may not be able to retain our key employees or attract, assimilate or retain other highly qualified technical and managerial personnel in the future. See Item 7: "Management's Discussion and Analysis - Risks Related to Our Business - We depend upon key employees and consultants in a competitive market for skilled personnel. If we are unable to attract and retain key personnel, it could adversely affect our ability to develop and market our products." 1998 MERGER WITH ACUTE THERAPEUTICS, INC. In June 1998, we completed the acquisition of the outstanding minority interest of our then majority-owned subsidiary, Acute Therapeutics, Inc., a Delaware corporation. Upon consummation of the merger, Robert J. Capetola, Ph.D., the then President and Chief Executive Officer of Acute Therapeutics, became our President and Chief Executive Officer.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS This Item 7: "Management's Discussion and Analysis of Financial Condition and Results of Operations" should be read in connection with our Consolidated Financial Statements. See Item 15: "Exhibits, Financial Statement Schedules, and Reports on Form 8-K." OVERVIEW We are a late-stage specialty pharmaceutical company applying our humanized lung surfactant technology to develop potential novel respiratory therapies and products. Surfactants are substances that are produced naturally in the lungs and are essential to the lungs' ability to absorb oxygen and to maintain proper airflow through the respiratory system. The absence or depletion of surfactant is involved in a number of respiratory diseases. Our humanized surfactant technology produces an engineered version of natural human lung surfactant and contains a peptide, sinapultide, that is designed to precisely mimic the essential human lung surfactant protein B (SP-B). Surfaxin(R), our lead product, is being developed initially for critical care patients with life-threatening respiratory disorders for which there are few, if any, approved therapies. Surfaxin is currently in two Phase 3 clinical trials for Respiratory Distress Syndrome in premature infants, a Phase 3 clinical trial for Meconium Aspiration Syndrome in full-term infants, and a Phase 2 clinical trial for Acute Respiratory Distress Syndrome in adults. Aerosolized formulations of our humanized surfactant are presently being developed to potentially treat hospitalized patients suffering from severe acute asthma and Acute Lung Injury, typically requiring mechanical ventilation. In addition, we believe there is the scientific rationale for the development of aerosolized formulations of our humanized surfactant to potentially treat COPD, sinusitis, sleep apnea and otitis media (inner ear infection). We are presently developing a dedicated sales and marketing capability through a collaboration with Quintiles to commercialize Surfaxin for neonatal indications in the United States. We also have entered into a strategic alliance with Esteve to commercialize Surfaxin in Europe and Latin America. We intend to establish additional strategic alliances, where appropriate, for the development and commercialization of our products in other indications and markets. Since our inception, we have incurred significant losses and, as of December 31, 2002, had a deficit accumulated during the development stage of approximately $73 million (including historical results of predecessor companies). The majority of our expenditures to date have been for research and development activities. Research and development expenses represent costs incurred for scientific and clinical personnel, clinical trials, regulatory filings and manufacturing efforts (including raw material costs). We expense our research and development costs as they are incurred. General and administrative expenses consist primarily of executive management, financial, business development, legal and general corporate activities and related expenses. See Item 7: "Management's Discussion and Analysis - Plan of Operations." 20

Historically, we have funded our operations with working capital provided principally through public and private equity financings and strategic collaborations. In November 2002, we completed the sale of securities in a private placement to selected institutional and accredited investors for gross proceeds of approximately $12.8 million. As of December 31, 2002, we had cash and investments of approximately $19.2 million, a secured revolving credit facility of $8.5 million to $10 million with Quintiles, of which $5.7 million was available for borrowing and $1.45 million was outstanding, and a $1 million capital equipment lease financing arrangement of which approximately $285,000 has been used. See Item 7: "Management's Discussion and Analysis - Liquidity and Capital Resources." CRITICAL ACCOUNTING POLICIES The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. We have identified below some of our more critical accounting policies and changes to accounting policies. For further discussion of our accounting policies see Footnote 2 "Summary of Significant Accounting Policies" in the Notes to Consolidated Financial Statements. See Item 15: "Exhibits, Financial Statement Schedules, and Reports on Form 8-K." Revenue Recognition - research and development collaborative agreements For up-front payments and licensing fees related to our contract research or technology, we defer and recognize revenue as earned over the life of the related agreement. Milestone payments are recognized as revenue upon achievement of contract-specified events and when there are no remaining performance obligations. Revenue earned under our research and development collaborative agreement contracts is recognized over a number of years as we perform research and development activities. For up-front payments and licensing fees related to our contract research or technology, we defer and recognize revenue as earned over the estimated period the services are expected to be performed. Research and Development Costs Research and development costs are expensed as incurred. We will continue to incur research and development costs as we continue to expand our product development activities. Our research and development costs have included, and will continue to include, expenses for internal development personnel, supplies and facilities, clinical trials, regulatory compliance and reviews, validation of processes and start up costs to establish commercial manufacturing capabilities. At the time our product candidates are approved by the FDA and we begin commercial manufacturing, we will no longer expense certain manufacturing costs as research and development costs. 21

PLAN OF OPERATIONS We expect to continue to incur increasing operating losses for the foreseeable future, primarily due to our continued research and development activities attributable to new and existing products, manufacturing, initial commercialization, and general and administrative activities. We anticipate that during the next 12 to 24 months we will: (i) significantly increase our research, development and regulatory activities. It is anticipated that our research and development activities will be the several clinical trials for Surfaxin indications and related regulatory filings. We are presently conducting a pivotal, multinational landmark Phase 3 trial treating up to 1,500 patients for the treatment of Respiratory Distress Syndrome in premature infants. This pivotal trial is intended, if successful, to provide the basis for New Drug Applications with the FDA and other worldwide regulatory authorities. This pivotal trial is expected to be completed and data announced early in the fourth quarter of 2003. We are also conducting another multinational Phase 3 trial treating up to 500 patients for the treatment of Respiratory Distress Syndrome in premature infants. This trial is expected to be completed within the same timeframe as the pivotal Phase 3 trial. We are currently evaluating whether to conclude this trial early to conserve financial resources and reallocate clinical resources to our pivotal Phase 3 trial. For Acute Respiratory Distress Syndrome in adults, we currently are conducting a Phase 2 dose-ranging safety and efficacy study of up to 110 patients in the United States. We expect to complete this trial in the third quarter of 2003. For Meconium Aspiration Syndrome in full-term infants, we currently are conducting a Phase 3 clinical trial of up to 200 patients in the United States. Enrollment is ongoing but has been slower than expected and completion is now anticipated in 2004. Given our belief in the importance of the pivotal Phase 3 trial for Respiratory Distress Syndrome in premature infants to our present development plan, resources have been and may continue to be reallocated from the Meconium Aspiration Syndrome program to the Respiratory Distress Syndrome program, as needed. We are conducting a Phase 2 clinical trial of Surfaxin lavage in up to 60 infant patients for use as a prophylactic for patients who are at risk for Meconium Aspiration Syndrome. The clinical trial and regulatory process is lengthy, expensive and uncertain and subject to numerous risks including, without limitation, the following risks discussed in the "Risks Related to Our Business" section: "The clinical trial and regulatory approval process for our products is expensive and time consuming, and the outcome is uncertain"; and "Our technology platform is based solely on our proprietary humanized, engineered surfactant technology and only our lead product candidate, Surfaxin, has been subject to clinical studies. Our ongoing Phase 3 clinical trials for Surfaxin for the treatment of Respiratory Distress Syndrome in premature infants may be delayed, or fail, which will harm our business." Aerosolized formulations of our humanized surfactant are presently being developed to potentially treat hospitalized patients suffering from severe acute asthma and Acute Lung Injury. In addition, we are evaluating the development of aerosolized formulations of our 22

humanized surfactant to potentially treat COPD, sinusitis, sleep apnea and otitis media (inner ear infection). (ii) invest in additional manufacturing capability in order to provide backup for the production of our humanized surfactant drug product and to scale up to meet clinical and commercial needs as they expand. (iii) invest in additional general and administrative resources primarily to support our business development initiatives, financial systems and controls and management information technologies. (iv) invest in marketing and commercialization management infrastructure to manage the strategic relationships with our collaborative partners for the launch of Surfaxin, if approved, and the execution of our "Discovery/Surfaxin" worldwide marketing strategy. In December 2001, we entered into a collaboration arrangement with Quintiles, and its affiliate, PharmaBio, to provide certain commercialization services in the United States for Surfaxin for the treatment of Respiratory Distress Syndrome in premature infants and Meconium Aspiration Syndrome in full-term infants. Quintiles will hire and train a dedicated United States sales force that will be branded in the market as ours. Quintiles will make available up to $70 million in post-launch funding to cover the first seven years of U.S. sales and marketing costs. In return, Quintiles will receive a commission on net sales of Surfaxin over a 10-year period. The Quintiles arrangement allows us to retain product ownership and have sales and marketing expertise in place for the commercialization of Surfaxin in the United States, if approved. In March 2002, we expanded our existing alliance with Esteve to develop, market and sell Surfaxin throughout Europe and Latin America. Esteve will provide certain commercialization services for Surfaxin for the treatment of Respiratory Distress Syndrome in premature infants, Meconium Aspiration Syndrome in full-term infants and Acute Lung Injury/Acute Respiratory Distress Syndrome in adult patients. Our exclusive supply agreement with Esteve provides that Esteve will purchase from us all of its Surfaxin drug product requirements at an established transfer price based on sales of Surfaxin by Esteve and/or its sublicensee(s). Esteve has also agreed to sponsor certain clinical trial costs related to obtaining regulatory approval in Europe for the Acute Lung Injury/Acute Respiratory Distress Syndrome indications. Esteve also agreed to make certain milestone payments to us upon the attainment of European marketing regulatory approval for Surfaxin. We will need to generate significant revenues from product sales and or related royalties and transfer prices to achieve and maintain profitability. Through December 31, 2002, we had no revenues from any product sales, and have not achieved profitability on a quarterly or annual basis. Our ability to achieve profitability depends upon, among other things, our ability to develop products, obtain regulatory approval for products under development and enter into agreements for product development, manufacturing and commercialization. In addition, our results are dependent upon the performance of our strategic partners and third party contract manufacturers and suppliers. Moreover, we may never achieve significant revenues or profitable operations from the sale of any of our products or technologies. 23

Through December 31, 2002, we had not generated taxable income. On December 31, 2002, net operating losses available to offset future taxable income for Federal tax purposes were approximately $65.1 million. The future utilization of such loss carryforwards may be limited pursuant to regulations promulgated under Section 382 of the Internal Revenue Code. In addition, we have a research and development tax credit carryforward of $1,225,000. The Federal net operating loss and research and development tax credit carryforwards expire beginning in 2008 and continuing through 2021. RESULTS OF OPERATIONS The net loss for the three years ended December 31, 2002, 2001 and 2000 was $17,443,000 (or $0.64 per common share), $11,146,000 (or $0.51 per common share), and $10,861,000 (or $0.58 per common share), respectively. These increased losses were primarily the result of increasing research and development expenditures as discussed below. Revenue Total revenues recognized for the three years ended December 31, 2002, 2001 and 2000 were $1,782,000, $1,112,000, and $741,000, respectively. These revenues are associated with our research and development collaborative arrangements, primarily our alliance with Esteve to develop, market and sell Surfaxin throughout Europe and Latin America. Additional collaborative revenues relate to our Small Business Innovative Research (SBIR) grant to develop Surfaxin for Acute Lung Injury/Acute Respiratory Distress Syndrome in adults and our Orphan Products Development grant to develop Surfaxin for Meconium Aspiration Syndrome in full-term infants. Expenses Research and development expenses for the three years ended December 31, 2002, 2001 and 2000 were $14,347,000, $8,007,000, and $7,494,000, respectively. The increases primarily reflect clinical trial costs incurred for our lead product, Surfaxin, currently in three Phase 3 trials and one Phase 2 trial for critical care patients with life threatening respiratory disorders, and research and development activities related to the development of aerosolized formulations of our humanized lung surfactant to potentially treat a variety of respiratory and upper airway conditions. General and administrative expenses for the three years ended December 31, 2002, 2001 and 2000 were $5,458,000, $5,067,000, and $5,145,000, respectively. General and administrative expenses consist primarily of costs of business and commercial development, executive management, financial and accounting, legal, facility and other administrative costs. Included in the year ended December 31, 2002, is a charge of $1,450,000 for pre-launch commercialization activities for Surfaxin in connection with a collaboration agreement with Quintiles (for which funding is provided by a secured, revolving credit facility with PharmaBio, discussed below in "Liquidity and Capital Resources"). Additionally, included in the years ended December 31, 2002, 2001, and 2000, are non-cash compensation charges of $402,000, $517,000, 24

and $2,515,000, respectively. The 2002 and 2001 non-cash compensation charges primarily relate to the grant of stock options to non-employee members of our Board of Directors under our stock option plan and certain modifications to certain options held by three departing members of our Board of Directors. The 2000 non-cash compensation charge is primarily related to the grant of stock options to non-employee members of our Board of Directors under the Company's Stock Option Plan and the vesting of certain milestone-based stock options. Other Income and Expense Interest income for the three years ended December 31, 2002, 2001, and 2000 was $724,000, $842,000 and $1,042,000, respectively. Interest income decreased primarily due to the decline in interest rates and the average balance of marketable securities throughout the three year period. Interest expense for the three years ended December 31, 2002, 2001, and 2000 was $144,000, $26,000 and $5,000, respectively. The increase in interest expense is primarily related to the secured, revolving credit facility with PharmaBio (discussed below in "Liquidity and Capital Resources"). LIQUIDITY AND CAPITAL RESOURCES Cash, Cash Equivalents and Marketable Securities As of December 31, 2002, we had cash, cash equivalents and marketable securities of approximately $19.2 million. Secured, Revolving Credit Facility and Capital Lease Arrangement In December 2001, we entered into a secured revolving credit facility of up to $8.5 million to $10 million with PharmaBio to fund pre-marketing activities for a Surfaxin launch in the United States. The credit facility is available for use until December 10, 2004, and monies become available in three tranches upon satisfying certain conditions. We have satisfied the conditions for availability of the first two tranches and at December 31, 2002, the amount available under the credit facility was approximately $5.7 million, of which $1.45 million was outstanding. Interest on amounts advanced under the credit facility will be payable quarterly in arrears. We may repay principal amounts owed by us under the credit facility from proceeds of milestone payments to be paid to us by PharmaBio upon the achievement of certain corporate milestones. We are obligated to use a significant portion of the funds borrowed under the credit facility for pre-launch marketing services to be provided by Quintiles. In December 2002, we entered into a lease financing arrangement with the Life Science and Technology Finance Division of General Electric Capital Corporation that provides, subject to certain conditions, for up to $1 million in financing for capital purchases. As of December 31, 2002, we had used approximately $285,000 of this financing arrangement. We believe our current working capital is sufficient to meet our planned research and development and operational activities into the second quarter of 2004. We will need additional 25

financing from investors or collaborators to complete research and development and commercialization of our current product candidates under development. Our working capital requirements will depend upon numerous factors, including, without limitation, the progress of our research and development programs, clinical trials, timing and cost of obtaining regulatory approvals, timing and cost of pre-launch marketing activities, levels of resources that we devote to the development of manufacturing and marketing capabilities, levels of resources that our collaboration partners devote to the development of sales and marketing capabilities, technological advances, status of competitors and our ability to establish collaborative arrangements with other organizations, the ability to defend and enforce our intellectual property rights and the establishment of additional strategic or licensing arrangements with other companies or acquisitions. Historically, the Company's working capital has been provided from the proceeds of private financings and strategic alliances: In November 2002, we completed the sale of securities in a private placement to selected institutional and accredited investors for net proceeds of approximately $11.9 million. We issued 6,397,517 shares of Common Stock and 2,878,883 Class I Warrants to purchase shares of Common Stock at an exercise price of $2.425 per share. The Class I warrants have a five-year term. Pursuant to our collaboration arrangement with Esteve on March 6, 2002, we issued 821,862 shares of Common Stock to Esteve at a purchase price equal to $4.867 per share and received a licensing fee of $500,000, for approximate net aggregate proceeds of $4.45 million. See Item 1: "Description of Business." Pursuant to the collaboration arrangement we entered into with Quintiles and PharmaBio in December 2001, we issued to PharmaBio, for approximate net aggregate proceeds of $2.7 million: (i) 791,905 shares of common stock at a price equal to $3.79 per share; and (ii) Class G warrants to purchase 357,143 shares of common stock at an exercise price equal to $3.485 per share (subject to adjustment). In connection with the credit facility, we issued to PharmaBio Class H warrants to purchase 320,000 shares of common stock. The Class H warrants are exercisable at $3.03 per share (subject to adjustment) and are exercisable proportionately only upon availability of the credit facility. To the extent the credit facility availability is increased to greater than $8.5 million, for each $1 million increase, the amount of shares of common stock issuable pursuant to the Class H warrants shall be increased by approximately 38,000 shares. See Item 1: "Description of Business." In October 2001, we received approximately $7.3 million in net proceeds from a private financing. In the financing, we issued 3,562,759 shares of common stock and 712,553 Class F warrants to purchase shares of common stock at an exercise price of $2.365 per share. The Class F warrants have a five-year term. In April 2001, we received approximately $1 million in proceeds in a private offering of 296,560 shares of common stock at a per share price equal to $3.37. 26

In March 2000, we received approximately $17,500,000 in net proceeds in a private placement offering from the sale of 2,902,846 shares of common stock and 580,567 Class E warrants to purchase common stock at $7.38 per share. The Class E warrants issued in the offering are exercisable through March 2005. In October 1999, in connection with our strategic alliance with Esteve, we issued to Esteve in a private placement 317,164 shares of common stock at a purchase price of $2.68 per share. In July 1999, we raised approximately $2,233,000 in net proceeds in a private placement offering of an aggregate of 2,024,792 shares of common stock and 2,024,792 Class D warrants to purchase common stock. All of the Class D warrants have been exercised. During March and April 1999, we raised $1.0 million in a private placement offering of 826,447 shares of common stock and 569,026 Class C warrants to purchase common stock at an exercise price of $2.15 per share. The Class C warrants are exercisable through April 2006. We will require substantial additional funding to conduct our business, including our expanded research and product development activities. Based on our current operating plan, we believe that our currently available resources will be adequate to satisfy our capital needs into the second quarter of 2004. Our future capital requirements will depend on the results of our research and development activities, clinical studies and trials, competitive and technological advances and the regulatory process. Our operations will not become profitable before we exhaust our current resources; therefore, we will need to raise substantial additional funds through additional debt or equity financings or through collaborative ventures with potential corporate partners. We may in some cases elect to develop products on our own instead of entering into collaboration arrangements and this would increase our cash requirements. Other than our credit facility with Esteve and our capital lease financing arrangement with General Electric Capital Corporation, we have not entered into any additional arrangements to obtain any additional financing. The sale of additional equity and debt securities may result in additional dilution to our stockholders, and we cannot be certain that additional financing will be available in amounts or on terms acceptable to us, if at all. If we fail to enter into collaborative ventures or to receive additional funding, we may have to reduce significantly the scope of or discontinue our planned research, development and commercialization activities, which could significantly harm our financial condition and operating results. Furthermore, we could cease to qualify for listing of our common stock on the NASDAQ SmallCap Market if the market price of our common stock declines as a result of the dilutive aspects of such potential financings. See "Risks Related to Our Business": " - We will need additional capital, and our ability to continue all of our existing planned research and development activities is uncertain. Any additional financing could result in equity dilution"; " - The market price of our stock may be adversely affected by market volatility"; and " - A substantial number of our securities are eligible for future sale and this could affect the market price for our stock and our ability to raise capital." 27

RISKS RELATED TO OUR BUSINESS The following risks, among others, could cause our actual results, performance, achievements or industry results to differ materially from those expressed in our forward-looking statements contained herein and presented elsewhere by management from time to time. BECAUSE WE ARE A DEVELOPMENT STAGE COMPANY, WE MAY NOT SUCCESSFULLY DEVELOP AND MARKET OUR PRODUCTS, AND EVEN IF WE DO, WE MAY NOT GENERATE ENOUGH REVENUE OR BECOME PROFITABLE. We are a development stage company. Therefore, you must evaluate us in light of the uncertainties and complexities present in a development stage biotechnology company. We currently have no products approved for sale and are conducting research and development on our product candidates. As a result, we have not begun to market or generate revenues from the commercialization of any of these products. Our long-term viability will be impaired if we are unable to obtain regulatory approval for, or successfully market, our product candidates. To date, we have only generated revenues from investments, research grants and collaborative research and development agreements. We will need to engage in significant, time-consuming and costly research, development, pre-clinical studies, clinical testing and regulatory approval for our products under development prior to their commercialization. In addition, pre-clinical or clinical studies may show that our products are not effective or safe for one or more of their intended uses. We may fail in the development and commercialization of our products. As of December 31, 2002, we have incurred a deficit accumulated during the development stage of approximately $72 million, and we expect to continue to incur significant increasing operating losses over the next several years. If we succeed in the development of our products, we still may not generate sufficient or sustainable revenues or we may not be profitable. OUR TECHNOLOGY PLATFORM IS BASED SOLELY ON OUR PROPRIETARY HUMANIZED, ENGINEERED SURFACTANT TECHNOLOGY AND ONLY OUR LEAD PRODUCT CANDIDATE, SURFAXIN, HAS BEEN SUBJECT TO CLINICAL STUDIES. OUR ONGOING PHASE 3 CLINICAL TRIALS FOR SURFAXIN FOR THE TREATMENT OF RESPIRATORY DISTRESS SYNDROME IN PREMATURE INFANTS MAY BE DELAYED, OR FAIL, WHICH WILL HARM OUR BUSINESS. Our humanized, engineered surfactant platform technology is based on the scientific rationale for surfactant replacement therapy to treat life threatening respiratory disorders and as the foundation for the development of novel respiratory therapies and products. Our business is dependent upon the successful development and approval of our product candidates based on this platform technology. Our lead product, Surfaxin, is currently in two Phase 3 clinical trials for Respiratory Distress Syndrome in premature infants, a Phase 3 clinical trial for Meconium Aspiration Syndrome in full-term infants, and a Phase 2 clinical trial for Acute Respiratory Distress syndrome in adults. Companies in the pharmaceutical and biotechnology industries have suffered significant setbacks in advanced clinical trials, even after obtaining promising results in earlier trials. Data obtained from tests are susceptible to varying interpretations which may delay, limit or prevent regulatory 28

approval. In addition, we may be unable to enroll patients quickly enough to meet our expectations for completing any or all of these trials. The timing and completion of current and planned clinical trials of our product candidates depend on, among other factors, the rate at which patients are enrolled, which is a function of many factors, including: - -- the number of clinical sites; - -- the size of the patient population; - -- the proximity of patients to the clinical sites; - -- the eligibility criteria for the study; - -- the existence of competing clinical trials; and - -- the existence of alternative available products. Delays in patient enrollment in clinical trials may occur, which would likely result in increased costs, program delays or both. WE WILL NEED ADDITIONAL CAPITAL, AND OUR ABILITY TO CONTINUE ALL OF OUR EXISTING PLANNED RESEARCH AND DEVELOPMENT ACTIVITIES IS UNCERTAIN. ANY ADDITIONAL FINANCING COULD RESULT IN EQUITY DILUTION. We will need substantial additional funding to conduct our presently planned research and product development activities. Based on our current operating plan, we believe that our currently available financial resources will be adequate to satisfy our capital needs into the second quarter of 2004. Our future capital requirements will depend on a number of factors that are uncertain, including the results of our research and development activities, clinical studies and trials, competitive and technological advances and the regulatory process, among others. We will likely need to raise substantial additional funds through collaborative ventures with potential corporate partners and through additional debt or equity financings. We may also continue to seek additional funding through capital lease transactions. We may in some cases elect to develop products on our own instead of entering into collaboration arrangements. This would increase our cash requirements for research and development. We have not entered into arrangements to obtain any additional financing, except for the credit facility with PharmaBio and our capital equipment lease financing arrangement with General Electric Capital Corporation. Any additional financing could include unattractive terms or result in significant dilution of stockholders' interests and share prices may decline. If we fail to enter into collaborative ventures or to receive additional funding, we may have to delay, scale back or discontinue certain of our research and development operations, and consider licensing the development and commercialization of products that we consider valuable and which we otherwise would have developed ourselves. If we are unable to raise required capital, we may be forced to limit many, if not all, of our research and development programs and related operations, curtail commercialization of out product candidates and, ultimately, cease operations. Furthermore, we could cease to qualify for listing of our securities on the NASDAQ SmallCap Market if the market price of our common stock declines as a result of the dilutive aspects of such potential financings. See "Risks Related to Our Business-The market price of our stock may be adversely affected by market volatility." 29

THE CLINICAL TRIAL AND REGULATORY APPROVAL PROCESS FOR OUR PRODUCTS IS EXPENSIVE AND TIME CONSUMING, AND THE OUTCOME IS UNCERTAIN. In order to sell our products that are under development, we must receive regulatory approvals for each product. The FDA and comparable agencies in foreign countries extensively and rigorously regulate the testing, manufacture, distribution, advertising, pricing and marketing of drug products like our products. This approval process includes preclinical studies and clinical trials of each pharmaceutical compound to establish its safety and effectiveness and confirmation by the FDA and comparable agencies in foreign countries that the manufacturer maintains good laboratory and manufacturing practices during testing and manufacturing. Although we are involved in certain late-stage clinical trials, pharmaceutical and biotechnology companies have suffered significant setbacks in advanced clinical trials, even after promising results in earlier clinical trials. The approval process is lengthy, expensive and uncertain. It is also possible that the FDA or comparable foreign regulatory authorities could interrupt, delay or halt any one or more of our clinical trials. If we, or any regulatory authorities, believe that trial participants face unacceptable health risks, any one or more of our trials could be suspended or terminated. We also may not reach agreement with the FDA and/or comparable foreign agencies on the design of any one or more of the clinical studies necessary for approval. Conditions imposed by the FDA and comparable agencies in foreign countries on our clinical trials could significantly increase the time required for completion of such clinical trials and the costs of conducting the clinical trials. Data obtained from clinical testing are susceptible to varying interpretations which may delay, limit or prevent regulatory approval. Delays and terminations of the clinical trials we conduct could result from insufficient patient enrollment. Patient enrollment is a function of several factors, including the size of the patient population, stringent enrollment criteria, the proximity of the patients to the trial sites, having to compete with other clinical trials for eligible patients, geographical and geopolitical considerations and others. Delays in patient enrollment can result in greater costs and longer trial timeframes. Patients may also suffer adverse medical events or side effects that are common to this class of drug such as a decrease in the oxygen level of the blood upon administration. Clinical trials generally take two to five years or more to complete, and, accordingly, our first product is not expected to be commercially available in the United States until at least 2004, and our other product candidates will take longer. The FDA has notified us that two of our intended indications for Surfaxin, Meconium Aspiration Syndrome in full-term infants and Acute Respiratory Distress Syndrome in adults, have been granted designation as "fast- track" products under provisions of the Food and Drug Administration Modernization Act of 1997, and the FDA has awarded us an Orphan Products Development Grant to support our development of Surfaxin for the treatment of Meconium Aspiration Syndrome. Fast-Track Status does not accelerate the clinical trials nor does it mean that the regulatory requirements are less stringent. The Fast-Track Status provisions are designed to expedite the FDA's review of new drugs intended to treat serious or life-threatening conditions. The FDA generally will review the New Drug Application 30

for a drug granted Fast-Track Status within six months instead of the typical one to three years. Our products may not, however, continue to qualify for expedited review and our other drug candidates may fail to qualify for fast track development or expedited review. Even though some of our drug candidates have qualified for expedited review, the FDA may not approve them at all or any sooner than other drug candidates that do not qualify for expedited review. The FDA and comparable foreign agencies could withdraw any approvals we obtain. Further, if there is a later discovery of unknown problems or if we fail to comply with other applicable regulatory requirements at any stage in the regulatory process, the FDA may restrict or delay our marketing of a product or force us to make product recalls. In addition, the FDA could impose other sanctions such as fines, injunctions, civil penalties or criminal prosecutions. To market our products outside the United States, we also need to comply with foreign regulatory requirements governing human clinical trials and marketing approval for pharmaceutical products. The FDA and foreign regulators have not yet approved any of our products under development for marketing in the United States or elsewhere. If the FDA and other regulators do not approve our products, we will not be able to market our products. IN ORDER TO CONDUCT OUR CLINICAL TRIALS WE NEED ADEQUATE SUPPLIES OF OUR DRUG SUBSTANCE AND DRUG PRODUCT AND COMPETITORS DRUG PRODUCT, WHICH MAY NOT BE READILY AVAILABLE. To succeed, clinical trials require adequate supplies of drug substance and drug product, which may be difficult or uneconomical to procure or manufacture. We rely on outside manufacturers for our drug substance and other active ingredients for Surfaxin and to produce material that meets appropriate standards for use in clinical studies for our products. We have validated only a single clinical manufacturing facility, owned and operated by Akorn to produce appropriate clinical grade material of our drug substance that meets standards for use in our ongoing clinical studies. Akorn has been experiencing significant operational and financial difficulties and is currently attempting to restructure its financial obligations and improve its day to day operations. In February 2003, Akorn informed us that certain operating difficulties experienced in one of its production rooms primarily used for the filling of sterile pharmaceutical had been rectified and that the room had been returned to operational status. Our ability to timely recommence Surfaxin manufacture for our Phase 2 clinical trial for Acute Respiratory Distress Syndrome in adults is dependent upon the success of Akorn's efforts to correct its difficulties and its ability to maintain operational status of the sterile production room and its other Surfaxin-related facilities. OUR STRATEGY, IN MANY CASES, IS TO ENTER INTO COLLABORATION AGREEMENTS WITH THIRD PARTIES WITH RESPECT TO OUR PRODUCTS AND WE MAY REQUIRE ADDITIONAL COLLABORATION AGREEMENTS. IF WE FAIL TO ENTER INTO THESE AGREEMENTS OR IF WE OR THE THIRD PARTIES DO NOT PERFORM UNDER SUCH AGREEMENTS, IT COULD IMPAIR OUR ABILITY TO COMMERCIALIZE OUR PRODUCTS. Our strategy for the completion of the required development and clinical testing of our products and for the manufacturing, marketing and commercialization of our products, in many cases, depends upon entering into collaboration arrangements with pharmaceutical companies to market, commercialize and distribute our products. In March 2002, we expanded our relationship with Esteve by entering into a collaboration arrangement with Esteve for Surfaxin covering all of Europe and Latin America. Esteve will be responsible for the marketing of 31

Surfaxin for the treatment of Respiratory Distress Syndrome in premature infants, Meconium Aspiration Syndrome in full-term infants, and Acute Lung Injury/Acute Respiratory Distress Syndrome in adults. Esteve will also be responsible for the sponsorship of certain clinical trial costs related to obtaining European Medicines Evaluation Agency approval for commercialization of Surfaxin in Europe for the Acute Lung Injury/Acute Respiratory Distress Syndrome indications. We will be responsible for the remainder of the regulatory activities relating to Surfaxin, including with respect to European Medicines Evaluation Agency filings. In December 2001, we entered into an exclusive collaboration arrangement in the United States with Quintiles, and its affiliate, PharmaBio, to commercialize, sell and market Surfaxin in the United States for indications of Respiratory Distress Syndrome and Meconium Aspiration Syndrome. As part of our collaboration with Quintiles, Quintiles will build a sales force solely dedicated to the sale of Surfaxin upon the approval of a New Drug Application for either of the two indications. If Quintiles and we fail to devote appropriate resources to commercialize, sell and market Surfaxin, sales of Surfaxin could be reduced. As part of the collaboration, PharmaBio is obligated to provide us with certain financial assistance in connection with the commercialization of Surfaxin, including, but not limited to, a secured, revolving credit facility for at least $8.5 million which may be increased to $10 million. A failure by us to repay amounts outstanding under the credit facility would have a material adverse effect on us. To obtain the benefits of such financing, we are obligated to meet certain development and performance milestones. The failure by us to meet the milestones or other terms and conditions of the financing leading to PharmaBio's termination thereof or the failure by PharmaBio to fulfill its obligation to partially fund the commercialization of Surfaxin, may affect our ability to successfully market Surfaxin. If Esteve, Quintiles or we breach or terminate the agreements that make up such collaboration arrangements or Esteve or Quintiles otherwise fail to conduct their Surfaxin-related activities in a timely manner or if there is a dispute about their respective obligations, we may need to seek other partners or we may have to develop our own internal sales and marketing capability for the indications of Surfaxin which Esteve and/or Quintiles have agreed to assist in commercializing. Accordingly, we may need to enter into additional collaboration agreements and our success, particularly outside of the United States, may depend upon obtaining additional collaboration partners. In addition, we may depend on our partners' expertise and dedication of sufficient resources to develop and commercialize our proposed products. We may, in the future, grant to collaboration partners rights to license and commercialize pharmaceutical products developed under collaboration agreements. Under these arrangements, our collaboration partners may control key decisions relating to the development of the products. The rights of our collaboration partners would limit our flexibility in considering alternatives for the commercialization of our products. If we fail to successfully develop these relationships or if our collaboration partners fail to successfully develop or commercialize any of our products, it may delay or prevent us from developing or commercializing our products in a competitive and timely manner and would have a material adverse effect on the commercialization of Surfaxin. See "Risks Related to Our Business-Our lack of marketing and sales experience could limit our ability to generate revenues from future product sales." 32

IF WE CANNOT PROTECT OUR INTELLECTUAL PROPERTY, OTHER COMPANIES COULD USE OUR TECHNOLOGY IN COMPETITIVE PRODUCTS. IF WE INFRINGE THE INTELLECTUAL PROPERTY RIGHTS OF OTHERS, OTHER COMPANIES COULD PREVENT US FROM DEVELOPING OR MARKETING OUR PRODUCTS. We seek patent protection for our drug candidates so as to prevent others from commercializing equivalent products in substantially less time and at substantially lower expense. The pharmaceutical industry places considerable importance on obtaining patent and trade secret protection for new technologies, products and processes. Our success will depend in part on our ability and that of parties from whom we license technology to: - -- defend our patents and otherwise prevent others from infringing on our proprietary rights; - -- protect trade secrets; and - -- operate without infringing upon the proprietary rights of others, both in the United States and in other countries. The patent position of firms relying upon biotechnology is highly uncertain and involves complex legal and factual questions for which important legal principles are unresolved. To date, the United States Patent and Trademark Office has not adopted a consistent policy regarding the breadth of claims that the United States Patent and Trademark Office allows in biotechnology patents or the degree of protection that these types of patents afford. As a result, there are risks that we may not develop or obtain rights to products or processes that are or may seem to be patentable. EVEN IF WE OBTAIN PATENTS TO PROTECT OUR PRODUCTS, THOSE PATENTS MAY NOT BE SUFFICIENTLY BROAD AND OTHERS COULD COMPETE WITH US. We, or the parties licensing technologies to us, have filed various United States and foreign patent applications with respect to the products and technologies under our development, and the United States Patent and Trademark Office and foreign patent offices have issued patents with respect to our products and technologies. These patent applications include international applications filed under the Patent Cooperation Treaty. Our pending patent applications, those we may file in the future or those we may license from third parties may not result in the United States Patent and Trademark Office or foreign patent office issuing patents. Also, if patent rights covering our products are not sufficiently broad, they may not provide us with sufficient proprietary protection or competitive advantages against competitors with similar products and technologies. Furthermore, if the United States Patent and Trademark Office or foreign patent offices issue patents to us or our licensors, others may challenge the patents or circumvent the patents, or the patent office or the courts may invalidate the patents. Thus, any patents we own or license from or to third parties may not provide any protection against competitors. Furthermore, the life of our patents is limited. We have licensed a series of patents from Johnson & Johnson and Ortho Pharmaceutical which are important, either individually or collectively, to our strategy of commercializing our surfactant technology. Such patents, which include relevant European patents, expire on various dates beginning in 2009 and ending in 2017 or, in some cases, possibly later. We have filed, and when possible and appropriate, will file, other patent applications with respect to our products and processes in the United States and in foreign 33

countries. We may not be able to develop additional products or processes that will be patentable or additional patents may not be issued to us. See also "Risks Related to Our Business-If we cannot meet requirements under our license agreements, we could lose the rights to our products." INTELLECTUAL PROPERTY RIGHTS OF THIRD PARTIES COULD LIMIT OUR ABILITY TO MARKET OUR PRODUCTS. Our commercial success also significantly depends on our ability to operate without infringing the patents or violating the proprietary rights of others. The United States Patent and Trademark Office keeps United States patent applications confidential while the applications are pending. As a result, we cannot determine which inventions third parties claim in pending patent applications that they have filed. We may need to engage in litigation to defend or enforce our patent and license rights or to determine the scope and validity of the proprietary rights of others. It will be expensive and time consuming to defend and enforce patent claims. Thus, even in those instances in which the outcome is favorable to us, the proceedings can result in the diversion of substantial resources from our other activities. An adverse determination may subject us to significant liabilities or require us to seek licenses that third parties may not grant to us or may only grant at rates that diminish or deplete the profitability of the products to us. An adverse determination could also require us to alter our products or processes or cease altogether any related research and development activities or product sales. IF WE CANNOT MEET REQUIREMENTS UNDER OUR LICENSE AGREEMENTS, WE COULD LOSE THE RIGHTS TO OUR PRODUCTS. We depend on licensing arrangements with third parties to maintain the intellectual property rights to our products under development. Presently, we have licensed rights from Johnson & Johnson and Ortho Pharmaceutical. These agreements require us to make payments and satisfy performance obligations in order to maintain our rights under these licensing arrangements. All of these agreements last either throughout the life of the patents, or with respect to other licensed technology, for a number of years after the first commercial sale of the relevant product. In addition, we are responsible for the cost of filing and prosecuting certain patent applications and maintaining certain issued patents licensed to us. If we do not meet our obligations under our license agreements in a timely manner, we could lose the rights to our proprietary technology. In addition, we may be required to obtain licenses to patents or other proprietary rights of third parties in connection with the development and use of our products and technologies. Licenses required under any such patents or proprietary rights might not be made available on terms acceptable to us, if at all. WE RELY ON CONFIDENTIALITY AGREEMENTS THAT COULD BE BREACHED AND MAY BE DIFFICULT TO ENFORCE. Although we believe that we take reasonable steps to protect our intellectual property, including the use of agreements relating to the non-disclosure of confidential information to third parties, 34

as well as agreements that purport to require the disclosure and assignment to us of the rights to the ideas, developments, discoveries and inventions of our employees and consultants while we employ them, the agreements can be difficult and costly to enforce. Although we seek to obtain these types of agreements from our consultants, advisors and research collaborators, to the extent that they apply or independently develop intellectual property in connection with any of our projects, disputes may arise as to the proprietary rights to this type of information. If a dispute arises, a court may determine that the right belongs to a third party, and enforcement of our rights can be costly and unpredictable. In addition, we will rely on trade secrets and proprietary know-how that we will seek to protect in part by confidentiality agreements with our employees, consultants, advisors or others. Despite the protective measures we employ, we still face the risk that: - -- they will breach these agreements; - -- any agreements we obtain will not provide adequate remedies for this type of breach or that our trade secrets or proprietary know-how will otherwise become known or competitors will independently develop similar technology; and - -- our competitors will independently discover our proprietary information and trade secrets. IF THE PARTIES WE DEPEND ON FOR MANUFACTURING OUR PHARMACEUTICAL PRODUCTS DO NOT TIMELY SUPPLY THESE PRODUCTS, IT MAY DELAY OR IMPAIR OUR ABILITY TO DEVELOP AND MARKET OUR PRODUCTS. We rely on outside manufacturers for our drug substance and other active ingredients for Surfaxin and to produce material that meets appropriate standards for use in clinical studies for our products. We have validated only a single clinical manufacturing facility owned and operated by Akorn to produce appropriate clinical grade material of our drug substance that meets standards for use in our ongoing clinical studies. Recently, Akorn has experienced a number of operational and financial difficulties that, although not directly involving the manufacturing process for our Surfaxin and other proprietary surfactant drug substance or drug product, may have an adverse effect on our clinical research and development activities. We will also rely on outside manufacturers for production of our products after marketing approval. We may also enter into arrangements with other manufacturers for the manufacture of materials for use in clinical testing and after marketing approval. Our outside manufacturers may not perform as they have agreed or may not remain in the contract manufacturing business for a sufficient time to successfully produce and market our product candidates. If we do not maintain important manufacturing relationships, we may fail to find a replacement manufacturer or to develop our own manufacturing capabilities. If we cannot do so, it could delay or impair our ability to obtain regulatory approval for our products and substantially increase our costs or deplete any profit margins. If we do find replacement manufacturers, we may not be able to enter into agreements with them on terms and conditions favorable to us and, there could be a substantial delay before a new facility could be qualified and registered with the FDA and foreign regulatory authorities. We may in the future elect to manufacture some of our products on our own. Although we own certain specialized manufacturing equipment, are considering an investment in additional 35

manufacturing equipment and employ certain manufacturing managerial personnel, we do not presently maintain a complete manufacturing facility or manufacturing department and we do not anticipate manufacturing on our own any of our products during the next 12 months. If we decide to manufacture products on our own and do not successfully develop manufacturing capabilities, it will adversely affect sales of our products. The FDA and foreign regulatory authorities require manufacturers to register manufacturing facilities. The FDA and corresponding foreign regulators also inspect these facilities to confirm compliance with good manufacturing practices (GMPs) or similar requirements that the FDA or corresponding foreign regulators establish. Manufacturing or quality control problems could occur at the contract manufacturers causing product production and shipment delays or a situation where the contractor may not be able to maintain compliance with the FDA's current GMP requirements necessary to continue manufacturing our drug substance. If our third-party foreign or domestic suppliers or manufacturers of our products or, if we decide to manufacture our products on our own, we, fail to comply with GMP requirements or other FDA and comparable foreign regulatory requirements, it could adversely affect our clinical research activities and our ability to market and develop our products. OUR LACK OF MARKETING AND SALES EXPERIENCE COULD LIMIT OUR ABILITY TO GENERATE REVENUES FROM FUTURE PRODUCT SALES. We do not have marketing, sales or distribution experience or marketing or sales personnel. As a result, we will depend on our collaboration with Quintiles for the marketing and sales of Surfaxin for indications of Respiratory Distress Syndrome in premature infants and Meconium Aspiration Syndrome in full-term infants in the United States and with Esteve for the marketing and sales of Surfaxin for the treatment of Respiratory Distress Syndrome, Meconium Aspiration Syndrome and Acute Lung Injury/Acute Respiratory Distress Syndrome in adult patients in all of Europe and Latin America. See "Risks Related to Our Business-Our strategy, in many cases, is to enter into collaboration agreements with third parties with respect to our products and we may require additional collaboration agreements. If we fail to enter into these agreements or if we or the third parties do not perform under such agreements, it could impair our ability to commercialize our products." If we do not develop a marketing and sales force of our own, then we will depend on arrangements with corporate partners or other entities for the marketing and sale of our remaining products. The sales and marketing of Surfaxin for indications of Respiratory Distress Syndrome in premature infants, Meconium Aspiration Syndrome in full-term infants, and Acute Lung Injury/Acute Respiratory Distress Syndrome in adult patients in the relevant territories depends, in part, on Quintiles' and Esteve's performance of their contractual obligations. The failure of either party to do so would have a material adverse effect on the sales and marketing of Surfaxin. We may not succeed in entering into any satisfactory third party arrangements for the marketing and sale of our remaining products. In addition, we may not succeed in developing marketing and sales capabilities, our commercial launch of certain products may be delayed until we establish marketing and sales capabilities or we may not have sufficient resources to do so. If we fail to establish marketing and sales capabilities or fail to enter into arrangements with third parties, either in a timely manner, it will adversely affect sales of our products. 36

WE DEPEND UPON KEY EMPLOYEES AND CONSULTANTS IN A COMPETITIVE MARKET FOR SKILLED PERSONNEL. IF WE ARE UNABLE TO ATTRACT AND RETAIN KEY PERSONNEL, IT COULD ADVERSELY AFFECT OUR ABILITY TO DEVELOP AND MARKET OUR PRODUCTS. We are highly dependent upon the principal members of our management team, especially our Chief Executive Officer, Dr. Capetola, and our directors, as well as our scientific advisory board members, consultants and collaborating scientists. Many of these people have been involved in our formation or have otherwise been involved with us for many years, have played integral roles in our progress and we believe that they will continue to provide value to us. A loss of any of these personnel may have a material adverse effect on aspects of our business and clinical development and regulatory programs. We have an employment agreement with Dr. Capetola that expires on December 31, 2005. We also have employment agreements with other key personnel with termination dates from 2003 through 2005. Although these employment agreements generally provide for severance payments that are contingent upon the applicable employee's refraining from competition with us, the loss of any of these persons' services would adversely affect our ability to develop and market our products and obtain necessary regulatory approvals, and the applicable noncompete provisions can be difficult and costly to monitor and enforce. Further, we do not maintain key-man life insurance. Our future success also will depend in part on the continued service of our key scientific and management personnel and our ability to identify, hire and retain additional personnel, including marketing and sales staff. We experience intense competition for qualified personnel, and the existence of non-competition agreements between prospective employees and their former employers may prevent us from hiring those individuals or subject us to suit from their former employers. While we attempt to provide competitive compensation packages to attract and retain key personnel, some of our competitors are likely to have greater resources and more experience than we have, making it difficult for us to compete successfully for key personnel. OUR INDUSTRY IS HIGHLY COMPETITIVE AND WE HAVE LESS CAPITAL AND RESOURCES THAN MANY OF OUR COMPETITORS, WHICH MAY GIVE THEM AN ADVANTAGE IN DEVELOPING AND MARKETING PRODUCTS SIMILAR TO OURS OR MAKE OUR PRODUCTS OBSOLETE. Our industry is highly competitive and subject to rapid technological innovation and evolving industry standards. We compete with numerous existing companies intensely in many ways. We intend to market our products under development for the treatment of diseases for which other technologies and treatments are rapidly developing and, consequently, we expect new companies to enter our industry and that competition in the industry will increase. Many of these companies have substantially greater research and development, manufacturing, marketing, financial, technological, personnel and managerial resources than we have. In addition, many of these competitors, either alone or with their collaborative partners, have significantly greater experience than we do in: - -- developing products; 37

- -- undertaking preclinical testing and human clinical trials; - -- obtaining FDA and other regulatory approvals or products; and - -- manufacturing and marketing products. Accordingly, our competitors may succeed in obtaining patent protection, receiving FDA or comparable foreign approval or commercializing products before us. If we commence commercial product sales, we will compete against companies with greater marketing and manufacturing capabilities who may successfully develop and commercialize products that are more effective or less expensive than ours. These are areas in which, as yet, we have limited or no experience. In addition, developments by our competitors may render our product candidates obsolete or noncompetitive. Presently, there are no approved drugs that are specifically indicated for Meconium Aspiration Syndrome in full-term infants or Acute Lung Injury/Acute Respiratory Distress Syndrome in adults. Current therapy consists of general supportive care and mechanical ventilation. Four products, three that are animal-derived and one that is a synthetic, are specifically approved for the treatment of Respiratory Distress Syndrome in premature infants. Exosurf(R) is synthetic and is marketed by GlaxoSmithKline, plc, outside the United States and contains only phospholipids (the fats normally present in the lungs) and synthetic organic detergents and no stabilizing protein or peptides. Curosurf(R) is a porcine lung extract that is marketed in Europe by Chiesi Farmaceutici S.p.A., and in the United States by Dey Laboratories, Inc. Survanta(R), marketed by the Ross division of Abbott Laboratories, Inc., is an extract of bovine lung that contains the cow version of surfactant protein B. Forrest Laboratories, Inc., markets its calf lung surfactant, Infasurf(R) in the United States for the treatment of Respiratory Distress Syndrome in premature infants. Although none of the four approved surfactants for Respiratory Distress Syndrome in premature infants is approved for Acute Lung Injury or Acute Respiratory Distress Syndrome in adults, which are significantly larger markets, there are a significant number of other potential therapies in development for the treatment of Acute Lung Injury/Acute Respiratory Distress Syndrome that are not surfactant-related. Any of these various drugs or devices could significantly impact the commercial opportunity for Surfaxin. We believe that engineered humanized surfactants such as Surfaxin will be far less expensive to produce than the animal-derived products approved for the treatment of Respiratory Distress Syndrome in premature infants and will have no capability of transmitting the brain-wasting bovine spongiform encephalopathy (commonly called "mad-cow disease") or causing adverse immunological responses in young and older adults. We also face, and will continue to face, competition from colleges, universities, governmental agencies and other public and private research organizations. These competitors are becoming more active in seeking patent protection and licensing arrangements to collect royalties for use of technology that they have developed. Some of these technologies may compete directly with the technologies that we are developing. These institutions will also compete with us in recruiting highly qualified scientific personnel. We expect that therapeutic developments in the areas in which we are active may occur at a rapid rate and that competition will intensify as advances in this field are made. As a result, we need to continue to devote substantial resources and efforts to research and development activities. 38

IF PRODUCT LIABILITY CLAIMS ARE BROUGHT AGAINST US, IT MAY RESULT IN REDUCED DEMAND FOR OUR PRODUCTS OR DAMAGES THAT EXCEED OUR INSURANCE COVERAGE. The clinical testing of, marketing and use of our products exposes us to product liability claims in the event that the use or misuse of those products causes injury, disease or results in adverse effects. Use of our products in clinical trials, as well as commercial sale, could result in product liability claims. In addition, sales of our products through third party arrangements could also subject us to product liability claims. We presently carry product liability insurance with coverages of up to $10,000,000 per occurrence and $10,000,000 in the aggregate, an amount we consider reasonable and customary relating to our clinical trials of Surfaxin. However, this insurance coverage includes various deductibles, limitations and exclusions from coverage, and in any event might not fully cover any potential claims. We may need to obtain additional product liability insurance coverage prior to initiating other clinical trials. We expect to obtain product liability insurance coverage before commercialization of our proposed products; however, the insurance is expensive and insurance companies may not issue this type of insurance when we need it. We may not be able to obtain adequate insurance in the future at an acceptable cost. Any product liability claim, even one that was not in excess of our insurance coverage or one that is meritless and/or unsuccessful, could adversely affect our cash available for other purposes, such as research and development. In addition, the existence of a product liability claim could affect the market price of our common stock. WE EXPECT TO FACE UNCERTAINTY OVER REIMBURSEMENT AND HEALTHCARE REFORM. In both the United States and other countries, sales of our products will depend in part upon the availability of reimbursement from third party payors, which include government health administration authorities, managed care providers and private health insurers. Third party payors are increasingly challenging the price and examining the cost effectiveness of medical products and services. DIRECTORS, EXECUTIVE OFFICERS, PRINCIPAL STOCKHOLDERS AND AFFILIATED ENTITIES OWN A SIGNIFICANT PERCENTAGE OF OUR CAPITAL STOCK, AND THEY MAY MAKE DECISIONS THAT YOU DO NOT CONSIDER TO BE IN YOUR BEST INTEREST. As of February 26, 2003, our directors, executive officers, principal stockholders and affiliated entities beneficially owned, in the aggregate, approximately 14% of our outstanding voting securities. As a result, if some or all of them acted together, they would have the ability to exert substantial influence over the election of our Board of Directors and the outcome of issues requiring approval by our stockholders. This concentration of ownership may have the effect of delaying or preventing a change in control of our company that may be favored by other stockholders. This could prevent transactions in which stockholders might otherwise recover a premium for their shares over current market prices. 39

THE MARKET PRICE OF OUR STOCK MAY BE ADVERSELY AFFECTED BY MARKET VOLATILITY. The market price of our common stock, like that of many other development stage pharmaceutical or biotechnology companies, has been and is likely to be volatile. In addition to general economic, political and market conditions, the price and trading volume of our stock could fluctuate widely in response to many factors, including: - -- announcements of the results of clinical trials by us or our competitors; - -- adverse reactions to products; - -- governmental approvals, delays in expected governmental approvals or withdrawals of any prior governmental approvals or public or regulatory agency concerns regarding the safety or effectiveness of our products; - -- changes in the United States or foreign regulatory policy during the period of product development; - -- developments in patent or other proprietary rights, including any third party challenges of our intellectual property rights; - -- announcements of technological innovations by us or our competitors; - -- announcements of new products or new contracts by us or our competitors; - -- actual or anticipated variations in our operating results due to the level of development expenses and other factors; - -- changes in financial estimates by securities analysts and whether our earnings meet or exceed the estimates; - -- conditions and trends in the pharmaceutical and other industries; - -- new accounting standards; and - -- the occurrence of any of the risks described in these "Management's Discussion and Analysis - Risks Related to Our Business." Our common stock is listed for quotation on the NASDAQ SmallCap Market. For the 12-month period ended December 31, 2002, the price of our common stock has ranged from $0.90 to $4.19. We expect the price of our common stock to remain volatile. The average daily trading volume in our common stock varies significantly. For the 12-month period ending December 31, 2002, the average daily trading volume in our common stock was approximately 50,072 shares and the average number of transactions per day was approximately 57. Our relatively low average volume and low average number of transactions per day may affect the ability of our stockholders to sell their shares in the public market at prevailing prices and a more active market may never develop. In addition, we may not be able to continue to adhere to the strict listing criteria of the SmallCap Market. If the common stock were no longer listed on the SmallCap Market, investors might only be able to trade in the over-the-counter market in the Pink Sheets(R) (a quotation medium operated by the National Quotation Bureau, LLC) or on the OTC Bulletin Board(R) of the National Association of Securities Dealers, Inc. This would impair the liquidity of our securities not only in the number of shares that could be bought and sold at a given price, which might be depressed by the relative illiquidity, but also through delays in the timing of transactions and reduction in media coverage. 40

In the past, following periods of volatility in the market price of the securities of companies in our industry, securities class action litigation has often been instituted against companies in our industry. If we face securities litigation in the future, even if meritless or unsuccessful, it would result in substantial costs and a diversion of management attention and resources, which would negatively impact our business. A SUBSTANTIAL NUMBER OF OUR SECURITIES ARE ELIGIBLE FOR FUTURE SALE AND THIS COULD AFFECT THE MARKET PRICE FOR OUR STOCK AND OUR ABILITY TO RAISE CAPITAL. The market price of our common stock could drop due to sales of a large number of shares of our common stock or the perception that these sales could occur. As of February 26, 2003, we had 32,856,526 shares of common stock outstanding. In addition, as of February 26, 2003, up to approximately 11,504,000 shares of our common stock were issuable on exercise of outstanding options and warrants. Holders of our stock options and warrants are likely to exercise them, if ever, at a time when we otherwise could obtain a price for the sale of our securities that is higher than the exercise price per security of the options or warrants. This exercise, or the possibility of this exercise, may impede our efforts to obtain additional financing through the sale of additional securities or make this financing more costly, and may reduce the price of our common stock. PROVISIONS OF OUR CERTIFICATE OF INCORPORATION AND DELAWARE LAW COULD DEFER A CHANGE OF OUR MANAGEMENT WHICH COULD DISCOURAGE OR DELAY OFFERS TO ACQUIRE US. Provisions of our Certificate of Incorporation and Delaware law may make it more difficult for someone to acquire control of us or for our stockholders to remove existing management, and might discourage a third party from offering to acquire us, even if a change in control or in management would be beneficial to our stockholders. For example, our Certificate of Incorporation allows us to issue shares of preferred stock without any vote or further action by our stockholders. Our Board of Directors has the authority to fix and determine the relative rights and preferences of preferred stock. Our Board of Directors also has the authority to issue preferred stock without further stockholder approval. As a result, our Board of Directors could authorize the issuance of a series of preferred stock that would grant to holders the preferred right to our assets upon liquidation, the right to receive dividend payments before dividends are distributed to the holders of common stock and the right to the redemption of the shares, together with a premium, prior to the redemption of our common stock. In addition, our Board of Directors, without further stockholder approval, could issue large blocks of preferred stock. ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK Our exposure to market risk is confined to our cash, cash equivalents and available for sale securities. We place our investments with high quality issuers and, by policy, limit the amount of credit exposure to any one issuer. We currently do not hedge interest rate or currency exchange exposure. We classify highly liquid investments purchased with a maturity of three months or less as "cash equivalents" and commercial paper and fixed income mutual funds as 41

"available for sale securities." Fixed income securities may have their fair market value adversely affected due to a rise in interest rates and we may suffer losses in principal if forced to sell securities that have declined in market value due to a change in interest rates.

DISCOVERY LABORATORIES, INC. AND SUBSIDIARY (a development stage company) NOTES TO CONSOLIDATED FINANCIAL STATEMENTS DECEMBER 31, 2002 NOTE 1 - THE COMPANY AND BASIS OF PRESENTATION Discovery Laboratories, Inc. (the "Company") is a late-stage specialty pharmaceutical company applying its humanized lung surfactant technology to develop potential novel respiratory therapies and products. Surfactants are substances that are produced naturally in the lungs and are essential to the lungs' ability to absorb oxygen and to maintain proper airflow through the respiratory system. The absence or depletion of surfactant is involved in a number of respiratory diseases. The Company's humanized surfactant technology produces an engineered version of natural human lung surfactant and contains a peptide, sinapultide, that is designed to precisely mimic the essential human lung surfactant protein B (SP-B). The Company believes that this proprietary surfactant technology is the only surfactant technology presently available to potentially treat a broad range of respiratory diseases. The Company's lead product, Surfaxin(R), is being developed initially for critical care patients with life-threatening respiratory disorders where there are few, if any, approved therapies. Surfaxin is currently in two Phase 3 clinical trials for Respiratory Distress Syndrome in premature infants, a Phase 3 clinical trial for Meconium Aspiration Syndrome in full-term infants, and a Phase 2 clinical trial for Acute Respiratory Distress Syndrome in adults. Aerosolized formulations of the Company's humanized surfactant are presently being developed to potentially treat patients suffering from severe acute asthma and Acute Lung Injury, the Company's lead preclinical programs, as well as COPD, sinusitis, and upper airway disorders such as sleep apnea and otitis media (inner ear infection). The Company is presently developing a dedicated sales and marketing capability through a collaboration with Quintiles Transnational Corp. ("Quintiles") to commercialize Surfaxin in neonatal indications in the United States. The Company has also entered into a strategic alliance with Laboratorios del Dr. Esteve ("Esteve") to commercialize Surfaxin in Europe and Latin America. The Company intends to establish strategic alliances, where appropriate, for the development and commercialization of the Company's products in other indications and markets. HISTORICAL FOUNDING TRANSACTIONS The Company, formerly known as Ansan Pharmaceuticals, Inc. ("Ansan"), was incorporated in Delaware on November 6, 1992. In November 1997, Ansan merged (the "Ansan Merger") with Discovery Laboratories, Inc. ("Predecessor Discovery") in a transaction accounted for as a reverse acquisition with Predecessor Discovery as the acquirer for financial reporting purposes since its stockholders owned approximately 92% of the merged entity. The consolidated financial statements include the accounts of Ansan from November 25, 1997 (the date of acquisition). In October 1996, the Company invested $7,500,000 in exchange for 600,000 shares of Series A preferred stock, of Acute Therapeutics, Inc., a Delaware Corporation ("ATI"). The stock represented 75% of the voting securities of ATI. In June 1998, ATI was merged with and into the Company (the "ATI Merger"). Pursuant to the ATI Merger, each outstanding share of ATI's Common Stock was exchanged for 3.90 shares (the "ATI Exchange Ratio") of the common stock ("Common Stock"), par value $0.001 per share, of the Company; each share of ATI's Series B preferred stock was converted into one share of the Company's Series C preferred stock and all outstanding options to purchase ATI Common Stock were assumed by the Company and became exercisable for shares of the Common Stock on the basis of the ATI Exchange Ratio. Transaction costs of $216,000 were incurred associated with the ATI Merger. The value of the Common Stock issued to ATI's Common Stockholders plus the assumption of the outstanding ATI options and merger related costs has been attributed to in-process research and development upon management's evaluation and was recorded as an expense in connection with the ATI Merger. The accompanying consolidated financial statements include the accounts of the Company and ATI (through the date of its merger into the Company). The Company currently maintains one subsidiary, which is inactive. F-9

DISCOVERY LABORATORIES, INC. AND SUBSIDIARY (a development stage company) NOTES TO CONSOLIDATED FINANCIAL STATEMENTS DECEMBER 31, 2002 MANAGEMENT'S PLANS AND FINANCINGS The Company is a development stage company and has incurred substantial losses since inception. To date, the Company has funded its operations primarily through the issuance of equity and strategic alliances. The Company expects to continue to expend substantial amounts for continued product research, development, and commercialization activities for the foreseeable future. Management's plans with respect to funding this development are to secure additional equity, if possible, and to secure additional strategic alliances that will provide available cash funding for operations. Continuation of the Company is dependent on its ability to obtain additional financing and, ultimately, on its ability to achieve profitable operations. There is no assurance, however, that such financing will be available or that the Company's efforts ultimately will be successful. NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES CASH AND CASH EQUIVALENTS The Company considers all highly liquid investments purchased with a maturity of three months or less to be cash equivalents. AVAILABLE-FOR-SALE MARKETABLE SECURITIES The investments are classified as available for sale and are comprised of shares of high quality fixed income commercial paper and mutual funds. Investments are carried at fair market value. Realized gains and losses are computed using the average cost of securities sold. Any appreciation/depreciation on these investments is recorded as other comprehensive income (loss) in the statements of changes in stockholders' equity until realized. PROPERTY AND EQUIPMENT Property and equipment is recorded at cost. Depreciation of furniture and equipment is computed using the straight-line method over the estimated useful lives of the assets (five to seven years). Leasehold improvements are amortized over the lower of the (a) term of the lease or (b) useful life of the improvements. USE OF ESTIMATES The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. LONG-LIVED ASSETS Statement of Financial Accounting Standards (SFAS) No. 144, "Accounting for the Impairment or Disposal of Long-Lived Assets", was issued in August 2001 and was adopted by the Company in 2002. Under SFAS No. 144, the Company is required to recognize an impairment loss only if the carrying amount of a long-lived asset is not recoverable from its undiscounted cash flows and measure any impairment loss as the difference between the carrying amount and the fair value of the asset. No impairment was recorded during the year ended December 31, 2002, as management of the Company believes the sum of its future undiscounted cash flows will exceed the carrying amount of the assets. RESEARCH AND DEVELOPMENT Research and development costs are charged to operations as incurred. F-10

DISCOVERY LABORATORIES, INC. AND SUBSIDIARY (a development stage company) NOTES TO CONSOLIDATED FINANCIAL STATEMENTS DECEMBER 31, 2002 REVENUE RECOGNITION - RESEARCH AND DEVELOPMENT COLLABORATIVE AGREEMENTS The Company received nonrefundable fees from companies under license, sublicense, collaboration and research funding agreements. The Company initially records such funds as deferred revenue and recognizes research and development collaborative contract revenue when the amounts are earned, which occurs over a number of years as the Company performs research and development activities. See Note 7 - License, Research Funding, and Commercialization Agreements for a detailed description of the Company's revenue recognition methodology under these agreements. Additionally, the Company has been awarded grants from certain third party organizations to help fund research for the drugs that the Company is attempting to bring to full commercial use. Once research and development expenditures qualifying under the grant are incurred, grant reports are periodically completed and submitted to the granting agency for review. If approved, the granting agency will then remit payment to the Company. Such amounts are recorded as revenue upon receipt. STOCK-BASED COMPENSATION The Company has adopted SFAS No. 123, "Accounting for Stock-Based Compensation". The provisions of SFAS No. 123 allow companies to either expense the estimated fair value of employee stock options or to continue to follow the intrinsic value method set forth in Accounting Principles Board Opinion 25, "Accounting for Stock Issued to Employees" ("APB 25") but disclose the pro forma effects on net income (loss) had the fair value of the options been expensed. The Company has elected to continue to apply APB 25 in accounting for its employee stock option incentive plans and to provide the required SFAS No. 123 disclosures. See Note 9 - Stock Options. NET LOSS PER COMMON SHARE Net loss per common share is computed pursuant to the provisions of Statement of Financial Accounting Standards No. 128, "Earnings per Share", and is based on the weighted average number of common shares outstanding for the periods. For the years ended December 31, 2002, 2001 and 2000, 4,032,000, 5,211,000 and 2,891,000 common shares, respectively, are potentially issuable upon the exercise of certain of the Company's stock options and warrants and are not included in the calculation of net loss per share as the effect would be anti-dilutive. RECLASSIFICATION Certain prior year balances have been reclassified to conform with the current presentation. The reclassification had no effect on net income. NOTE 3 - INVESTMENTS The available-for-sale marketable securities are as follows: December 31, -------------------------------- 2002 2001 ------------- ------------- Cost $ 10,475,000 $ 12,866,000 Gross unrealized gain 178,000 131,000 Gross unrealized loss (1,000) (59,000) ------------- ------------ Estimated fair value $ 10,652,000 $ 12,938,000 ============= ============ F-11

DISCOVERY LABORATORIES, INC. AND SUBSIDIARY (a development stage company) NOTES TO CONSOLIDATED FINANCIAL STATEMENTS DECEMBER 31, 2002 NOTE 4 - NOTE RECEIVABLE Note receivable pertains to a $200,000, 7% per annum mortgagor's note due from a vice president of the Company. This note is secured by a mortgage agreement dated July 24, 2001. The note calls for monthly payments of principal and interest over a 360-month period. The principal balance outstanding at December 31, 2002 and 2001 was approximately $197,000 and $199,000, respectively. NOTE 5 - PROPERTY AND EQUIPMENT Property and equipment as of December 31, 2002 and 2001 was comprised of the following: December 31, -------------------------- 2002 2001 ---------- ---------- Leashold Improvements $ 144,000 $ 144,000 Furniture 239,000 189,000 Equipment 1,600,000 989,000 ---------- ---------- 1,983,000 1,322,000 Less accumulated depreciation 752,000 500,000 ---------- ---------- $1,231,000 $ 822,000 ========== ========== The equipment balance at December 31, 2002 and 2001 includes $559,000 and $125,000, respectively, of property subject to a capital lease. The related accumulated depreciation was $57,000 and $26,000 at December 31, 2002 and 2001, respectively. As of December 31, 2002, the Company had construction commitments outstanding totaling approximately $188,000 related to the enhancement of manufacturing capabilities for Surfaxin. NOTE 6 - INCOME TAXES Since its inception, the Company has never recorded a provision or benefit for Federal and state income taxes. The reconciliation of the income tax benefit computed at the Federal statutory rates to the Company's recorded tax benefit for the years ended December 31, 2002, 2001, and 2000 are as follows: December 31, ----------------------------------------- 2002 2001 2000 ----------- ----------- ----------- Income tax benefit, statutory rates $ 5,938,000 $ 3,783,000 $ 3,652,000 State taxes on income, net of federal benefit 1,088,000 698,000 836,000 Research and development tax credit 274,000 90,000 85,000 Other (755,000) 3,000 (95,000) ----------- ----------- ----------- Income tax benefit 6,545,000 4,574,000 4,478,000 Valuation allowance (6,545,000) (4,574,000) (4,478,000) ----------- ----------- ----------- Income tax benefit $ -- $ -- $ -- =========== =========== =========== F-12

DISCOVERY LABORATORIES, INC. AND SUBSIDIARY (a development stage company) NOTES TO CONSOLIDATED FINANCIAL STATEMENTS DECEMBER 31, 2002 The tax effects of temporary differences that give rise to deferred tax assets and deferred tax liabilities, at December 31, 2002 and 2001, are as follows: December 31, ----------------------------- 2002 2001 ------------ ------------- Long-term deferred tax assets: Net operating loss carryforwards (federal and state) $ 25,526,000 $ 19,275,000 Research and development tax credits 1,225,000 846,000 Capitalized research and development 222,000 268,000 ------------ ------------ Total long-term deferred tax assets 26,973,000 20,389,000 ------------ ------------ Long-term deferred tax liabilities: Property and equipment (108,000) (69,000) ------------ ------------ Net deferred tax assets 26,865,000 20,320,000 Less: valuation allowance (26,865,000) (20,320,000) ------------ ------------ $ -- $ -- ============ ============ The Company was in a net deferred tax asset position at December 31, 2002 and 2001 before the consideration of a valuation allowance. Due to the fact that the Company is in the development stage and has never realized a profit, management has fully reserved the net deferred tax asset since realization is not assured. At December 31, 2002 and 2001, the Company had available carryforward net operating losses for Federal tax purposes of approximately $65,112,000 and $47,496,000, respectively, and a research and development tax credit carryforward of $1,225,000 and $846,000, respectively. The Federal net operating loss and research and development tax credit carryforwards expire beginning in 2008 and continuing through 2021. Additionally, at December 31, 2002 and 2001, the Company had available carryforward losses of approximately $51,385,000 and $43,244,000, respectively, for state tax purposes. The utilization of the Federal net operating loss carryforwards is subject to annual limitations in accordance with Section 382 of the Internal Revenue Code. Certain state carryforward net operating losses are also subject to annual limitations. The difference between the deficit accumulated during the development stage for financial reporting purposes and the net operating loss carryforwards for tax purposes is primarily due to the write-off of the acquired in-process research and development and supplies, which were not deducted for tax purposes. NOTE 7 - LICENSE, RESEARCH FUNDING, AND COMMERCIALIZATION AGREEMENTS In March 2002, the Company expanded its existing alliance with Esteve to develop, market and sell Surfaxin throughout Europe and Latin America. In connection with this new Esteve collaboration, Esteve purchased 821,862 shares of Common Stock for an aggregate consideration of $4 million (at a 50% premium over the average closing price for the 30 days prior to the closing date) and paid the Company a non-refundable licensing fee of $500,000. Esteve agreed to provide certain commercialization services for Surfaxin for the treatment of Respiratory Distress Syndrome in premature infants, Meconium Aspiration Syndrome in full-term infants and Acute Lung Injury/Acute Respiratory Distress Syndrome in adult patients. The Company has agreed to an exclusive supply agreement which provides that Esteve will purchase from the Company all of its Surfaxin drug product requirements at an established transfer price based on sales of Surfaxin by Esteve and/or its sublicensee(s). Esteve has also agreed to sponsor certain clinical trial costs related to obtaining regulatory approval in Europe for Acute Lung Injury/Acute Respiratory Distress Syndrome indications. Further, Esteve also agreed to make certain milestone payments to the Company upon the attainment of European marketing regulatory approval of Surfaxin. F-13

DISCOVERY LABORATORIES, INC. AND SUBSIDIARY (a development stage company) NOTES TO CONSOLIDATED FINANCIAL STATEMENTS DECEMBER 31, 2002 In October 1999, the Company granted an exclusive license to Esteve to commercialize and sell Surfaxin within Central and South America, Mexico and certain Southern European countries (with an option to include Italy). This license was terminated and superseded by the collaboration entered into with Esteve in March 2002, discussed above. In connection with this exclusive license, the Company received a nonrefundable license fee of $375,000, an additional $375,000 in advance for Surfaxin supplied for certain clinical trials to be conducted in the licensed territory; and Esteve agreed to reimburse certain research and development expenditures borne by the Company in conducting such clinical trials. In addition, an affiliate of Esteve invested $850,000 in the Company in exchange for Common Stock issued at a 50% premium over the ten-day average closing price preceding the closing of the investment; the Company has accounted for the premium as additional license fees amounting to $286,000. The Company has accounted for the license fees (including the $286,000 premium paid for Common Stock), the reimbursement of research and development expenditures, and the advance payment for Surfaxin received from Esteve to be used in clinical trials as deferred revenue. The balance in deferred revenue at December 31, 2002 relates entirely to the license agreement with Esteve for which the Company will recognize revenue using a straight line method through the anticipated date of FDA approval for the first Surfaxin neonatal indication. On December 10, 2001, the Company entered into a collaboration arrangement with Quintiles and its affiliate, PharmaBio Development, Inc. ("PharmaBio"), whereby Quintiles will provide pre- and post-launch marketing services for the commercialization of Surfaxin for Respiratory Distress Syndrome in premature infants and/or for Meconium Aspiration Syndrome in full-term infants in the United States. In connection therewith, the Company issued to PharmaBio for aggregate consideration of $3 million: (i) 791,905 shares of Common Stock; (ii) Class G warrants to purchase 357,143 shares of Common Stock at an exercise price equal to $3.485 per share; and (iii) Class H warrants to purchase 320,000 shares of Common Stock at an exercise price equal to $3.03 per share. PharmaBio also committed to provide the Company with a secured revolving credit facility (the "Credit Facility"), primarily for use to pay pre-launch marketing services to be provided by Quintiles, subject to the Company satisfying certain conditions, for up to $8.5 million, which may be increased to $10 million in specified circumstances. To the extent the Credit Facility availability is increased to greater than $8.5 million, for each $1 million dollar increase, the amount of shares of Common Stock issuable pursuant to the Class H warrants will be increased by approximately 38,000 shares. Principal amounts owed under the Credit Facility may be paid out of the proceeds of milestone payments to be paid by PharmaBio to the Company at certain intervals upon the achievement of certain corporate milestones by the Company. At December 31, 2002, $1,450,000 was outstanding under the Credit Facility. At December 31, 2001, no amounts were outstanding. The Company and Ortho Pharmaceuticals, Inc., a wholly-owned subsidiary of Johnson & Johnson, Inc., are parties to an agreement granting an exclusive license of the Surfaxin technology to the Company in exchange for certain license fees ($200,000 of which was paid in November 1996), milestone payments aggregating $2,750,000 and royalties. The Company and The Scripps Research Institute ("Scripps") are parties to a research funding and option agreement which expires in February 2005, subject to termination by the Company at any time with 90 days prior notice. Pursuant to this agreement, the Company is obligated to fund a portion of Scripps' research efforts and thereby has the option to acquire an exclusive worldwide license to the technology developed from the research program during the term of the agreement. Scripps owns all of the technology that it developed pursuant to work performed under the agreement. To the extent the Company does not exercise its option to technology developed under the agreement, the Company has the right to receive 50% of the net royalty income received by Scripps for inventions that are jointly developed under the agreement. Payments to Scripps under this agreement were $572,000, $508,000 and $468,000 in 2002, 2001 and 2000, respectively. F-14

COMMON SHARES RESERVED FOR ISSUANCE As of December 31, 2002 and 2001, the Company has reserved shares of Common Stock for issuance upon exercise of options and warrants as follows: December 31, ---------------------- 2002 2001 --------- --------- Stock option plans 4,908,000 4,275,000 Placement agent and underwriter warrants 1,610,000 1,619,000 Class C warrants (1999 private placement) 57,000 57,000 Class E warrants (2000 private placement) 581,000 581,000 Class F warrants (2001 private placement) 713,000 713,000 Class G warrants (2001 Quintiles Alliance) 357,000 357,000 Class H warrants (2001 Quintiles Credit Facility) 565,000 565,000 Class I warrants (2002 private placement) 2,879,000 -- Other warrants 75,000 115,000 ---------- ---------- 11,745,000 8,282,000 ========== ========== TREASURY STOCK/COMMON STOCK ISSUED FOR SERVICES In 1998, the Company's Board of Directors ("Board of Directors") approved a stock repurchase program wherein the Company could buy its own shares from the open market and use such shares to settle indebtedness. Such shares are accounted for as treasury stock. During 2002, the Company did not acquire, nor did it issue, any Common Stock accounted for as treasury stock. During 2001, the Company acquired 11,500 shares of Common Stock for approximately $26,000. Such shares are accounted for as treasury stock. In addition, during 2001, the Company issued 10,902 shares of Common Stock in lieu of cash payments for services and rent. During 2000, the Company acquired 31,743 shares of Common Stock in exchange for option conversions, having a value of $245,000, and issued 7,000 shares of treasury stock in satisfaction of services rendered. In addition, during 2000, the Company issued 9,496 shares of Common Stock in lieu of cash payments for services and rent. During 1999, the Company acquired 2,000 shares of Common Stock for approximately $5,000 and issued 15,600 shares of treasury stock, having a value of approximately $53,000, in settlement of $39,000 of indebtedness. The difference between fair market value and amount of indebtedness was charged to expense and credited to paid-in-capital. SERIES C PREFERRED STOCK The Company's Series C redeemable convertible preferred stock was convertible at the option of the holder into Common Stock at a conversion price equal to the market price of the Common Stock, as defined. On March 3, 2000, the sole Series C shareholder, Johnson & Johnson, Inc., elected to convert its Series C preferred stock shares into 398,186 shares of Common Stock. F-16

NOTE 9 - STOCK OPTIONS In March 1998, the Company adopted its 1998 Stock Incentive Plan which includes three equity programs (the "1998 Plan"). Under the Discretionary Option Grant Program, options to acquire shares of the Common Stock may be granted to eligible persons who are employees, non-employee directors, consultants and other independent advisors. Pursuant to the Stock Issuance Program, such eligible persons may be issued shares of the Common Stock. Under the Automatic Option Grant Program, eligible non-employee directors will automatically receive option grants at periodic intervals at an exercise price equal to the fair market value per share on the date of the grant. Options granted under the 1998 Plan expire no later than ten years from the date of the grant. The 1998 Plan was successively amended at each of the Annual Meeting of Stockholders for the years 2002, 2001 and 2000, to increase the maximum number of shares of Common Stock reserved for issuance over the term of the plan by 1,000,000 shares, 1,150,000 shares and 799,041 shares, respectively. After giving effect to these amendments, there are currently 5,150,000 shares of Common Stock reserved for issuance over the term of the plan. In addition, in 2002 the Board of Directors approved amendments to the 1998 Plan that (i) increased the exercise price of options granted to non-employee directors pursuant to the Automatic Option Grant Program from 60% of the fair market value per share on the date of the grant to 100% of such fair market value and (ii) removed the Plan Administrator's authority to effect the cancellation and regrant of any outstanding options under the Discretionary Option Grant Program. The Company applies APB 25 in accounting for stock options and, accordingly, recognizes compensation expense for the difference between the fair value of the underlying Common Stock and the exercise price of the option at the date of grant. The effect of applying SFAS No. 123 on pro forma net loss is not necessarily representative of the effects on reported net income or loss for future years due to, among other things, (i) the vesting period of the stock options and (ii) the fair value of additional stock options in future years. Had compensation cost for the Company's stock option plans been determined based upon the fair value of the options at the grant date of awards under the plans consistent with the methodology prescribed under SFAS No. 123, the Company's net loss for each of the years ended December 31, 2002, 2001 and 2000 would have been approximately $18,586,000 or $0.68, $13,455,000 or $0.61 per share and $14,092,000 or $0.75 per share per share, respectively. The weighted average fair value of the options granted are estimated at $1.15, $1.93 and $3.40 per share, respectively, for the years ended December 31, 2002, 2001 and 2000, on the date of grant using the Black-Scholes option-pricing model with the following weighted average assumptions: dividend yield 0%, volatility of 95%, 118% and 130%, respectively, risk-free interest rate of 2.5%, 4% and 6%, respectively and expected life of three and a half years.

Such repurchase rights lapse as the options vest according to their stated terms. In September 1999, management was granted, in the aggregate, options to purchase 500,000 shares of the Common Stock subject to the achievement of certain corporate milestones. In January 2000, certain milestones related to the options had been achieved and 50% of the 250,000 related options vested. In September 2000, the Board of Directors accelerated the remaining 50% of the 250,000 milestone options and the Company incurred non-cash compensation charges amounting to $2,515,000, representing the excess of the fair value over the exercise price of the options granted. Included in the options outstanding at December 31, 2001, are options to purchase 123,200 shares of Common Stock (at an exercise price of $4.44) granted during 1998, which vest upon the Company achieving specified milestones and expire in June 2008. In December 2002, the related milestones were achieved. F-18

DISCOVERY LABORATORIES, INC. AND SUBSIDIARY (a development stage company) NOTES TO CONSOLIDATED FINANCIAL STATEMENTS DECEMBER 31, 2002 In December 2002, the Board of Directors approved the issuance of options to management to purchase up to 800,000 shares of Common Stock at an exercise price of $2.75 per share. Such options are expressly subject to the requisite approval of the Company's shareholders, obtained no later than the Company's Annual Meeting of Shareholders for 2003, for an amendment to the 1998 Plan authorizing an increase in the number of shares issuable under the plan in an amount equal to or greater than the aggregate amount of such options. Accordingly, such options are not included in the options outstanding at December 31, 2002. Provided the shareholders of the Company approve such amendment, such options shall vest in their entirety upon the fourth anniversary of the date of grant or at such earlier time, if ever, upon the receipt by the Company of a New Drug Application (NDA) approval by the United States Food and Drug Administration for Surfaxin for either Respiratory Distress Syndrome in premature infants, Meconium Aspiration Syndrome in full-term infants, or Acute Respiratory Distress Syndrome in adults.

Each payment may, at the option of the Payee, be calculated and applied on an
assumption that such payment would be made on its due date.

The acceptance by Payee of any payment which is less than payment in full of all
amounts due and owing at such time shall not constitute a waiver of Payee's
right to receive payment in full at such time or at any prior or subsequent
time.

The Maker hereby expressly authorizes the Payee to insert the date value is
actually given in the blank space on the face hereof and on all related
documents pertaining hereto.

This Note may be secured by a security agreement, chattel mortgage, pledge
agreement or like instrument (each of which is hereinafter called a "Security
Agreement").

Time is of the essence hereof. If any installment or any other sum due under
this Note or any Security Agreement is not received within ten (10) days after
its due date, the Maker agrees to pay, in addition to the amount of each such
installment or other sum, a late payment charge of five percent (5%) of the
amount of said installment or other sum, but not exceeding any lawful maximum.
If (i) Maker fails to make payment of any amount due hereunder within ten (10)
days after the same becomes due and payable; or (ii) Maker is in default under,
or fails to perform under any term or condition contained in any Security
Agreement, then the entire principal sum remaining unpaid, together with all
accrued interest thereon and any other sum payable under this Note or any
Security Agreement, at the election of Payee, shall immediately become due and
payable, with interest thereon at the lesser of eighteen percent (18%) per annum
or the highest rate not prohibited by applicable law from the date of such
accelerated maturity until paid (both before and after any judgment).

Notwithstanding anything to the contrary contained herein or in the Security
Agreement, Maker may not prepay in full or in part any indebtedness hereunder
without the express written consent of Payee in its sole discretion.

It is the intention of the parties hereto to comply with the applicable usury
laws; accordingly, it is agreed that, notwithstanding any provision to the
contrary in this Note or any Security Agreement, in no event shall this Note or
any Security Agreement require the payment or permit the collection of interest
in excess of the maximum amount permitted by applicable law. If any such excess
interest is contracted for, charged or received under this Note or any Security
Agreement, or if all of the principal balance shall be prepaid, so that under
any of such circumstances the

amount of interest contracted for, charged or received under this Note or any Security Agreement on the principal balance shall exceed the maximum amount of interest permitted by applicable law, then in such event (a) the provisions of this paragraph shall govern and control, (b) neither Maker nor any other person or entity now or hereafter liable for the payment hereof shall be obligated to pay the amount of such interest to the extent that it is in excess of the maximum amount of interest permitted by applicable law, (c) any such excess which may have been collected shall be either applied as a credit against the then unpaid principal balance or refunded to Maker, at the option of the Payee, and (d) the effective rate of interest shall be automatically reduced to the maximum lawful contract rate allowed under applicable law as now or hereafter construed by the courts having jurisdiction thereof. It is further agreed that without limitation of the foregoing, all calculations of the rate of interest contracted for, charged or received under this Note or any Security Agreement which are made for the purpose of determining whether such rate exceeds the maximum lawful contract rate, shall be made, to the extent permitted by applicable law, by amortizing, prorating, allocating and spreading in equal parts during the period of the full stated term of the indebtedness evidenced hereby, all interest at any time contracted for, charged or received from Maker or otherwise by Payee in connection with such indebtedness; provided, however, that if any applicable state law is amended or the law of the United States of America preempts any applicable state law, so that it becomes lawful for the Payee to receive a greater interest per annum rate than is presently allowed, the Maker agrees that, on the effective date of such amendment or preemption, as the case may be, the lawful maximum hereunder shall be increased to the maximum interest per annum rate allowed by the amended state law or the law of the United States of America. The Maker and all sureties, endorsers, guarantors or any others (each such person, other than the Maker, an "Obligor") who may at any time become liable for the payment hereof jointly and severally consent hereby to any and all extensions of time, renewals, waivers or modifications of, and all substitutions or releases of, security or of any party primarily or secondarily liable on this Note or any Security Agreement or any term and provision of either, which may be made, granted or consented to by Payee, and agree that suit may be brought and maintained against any one or more of them, at the election of Payee without joinder of any other as a party thereto, and that Payee shall not be required first to foreclose, proceed against or exhaust any security hereof in order to enforce payment of this Note. The Maker and each Obligor hereby waives presentment, demand for payment, notice of nonpayment, protest, notice of protest, notice of dishonor, and all other notices in connection herewith, as well as filing of suit (if permitted by law) and diligence in collecting this Note or enforcing any of the security hereof, and agrees to pay (if permitted by law) all expenses incurred in collection, including Payee's actual attorneys' fees. Maker and each Obligor agrees that fees not in excess of twenty percent (20%) of the amount then due shall be deemed reasonable. Maker hereby irrevocably authorizes and empowers the Prothonotary or Clerk, or any attorney for any Court of record to appear for Maker in such Courts, at any time, and confess a judgement against Maker, without process, in favor of any holder hereof, without the filing of a declaration of default, with release of errors, without stay of execution, for such amount as may appear from the face hereof to be due hereunder (or, if such attorney so elects, for the amount which may be due hereon as evidenced by an affidavit signed by a representative of holder setting forth the amount then due) together with charges, attorney's fees and costs as herein provided, and Maker hereby waives and releases all benefits and relief from any and all appraisement, stay or exemption laws of any state, now in force or hereafter to be passed. If a copy hereof, verified by an affidavit, shall have been filed in said proceeding, it shall not be necessary to file the original as a warrant of attorney. No single exercise of the foregoing warrant and power to confess judgement shall be deemed to exhaust the power, whether or not such exercise shall be held by any Court to be invalid, voidable, or void, but the power shall continue undiminished and may be exercised from time to time as often as the holder hereof shall elect, until all sums payable or that may become payable hereunder by Maker have been paid in full. THE MAKER HEREBY UNCONDITIONALLY WAIVES ITS RIGHTS TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING OUT OF, DIRECTLY OR INDIRECTLY, THIS NOTE, ANY OF THE RELATED DOCUMENTS, ANY DEALINGS BETWEEN MAKER AND PAYEE RELATING TO THE SUBJECT MATTER OF THIS TRANSACTION OR ANY RELATED TRANSACTIONS, AND/OR THE RELATIONSHIP THAT IS BEING ESTABLISHED BETWEEN MAKER AND PAYEE. THE SCOPE OF THIS WAIVER IS INTENDED TO BE ALL ENCOMPASSING OF ANY AND ALL DISPUTES THAT MAY BE FILED IN ANY COURT (INCLUDING, WITHOUT LIMITATION, CONTRACT CLAIMS, TORT CLAIMS, BREACH OF DUTY CLAIMS, AND ALL OTHER COMMON LAW AND STATUTORY CLAIMS.) THIS WAIVER IS IRREVOCABLE MEANING

THAT IT MAY NOT BE MODIFIED EITHER ORALLY OR IN WRITING, AND THE WAIVER SHALL APPLY TO ANY SUBSEQUENT AMENDMENTS, RENEWALS, SUPPLEMENTS OR MODIFICATIONS TO THIS NOTE, ANY RELATED DOCUMENTS, OR TO ANY OTHER DOCUMENTS OR AGREEMENTS RELATING TO THIS TRANSACTION OR ANY RELATED TRANSACTION. IN THE EVENT OF LITIGATION, THIS NOTE MAY BE FILED AS A WRITTEN CONSENT TO A TRIAL BY THE COURT. This Note and any Security Agreement constitute the entire agreement of the Maker and Payee with respect to the subject matter hereof and supercedes all prior understandings, agreements and representations, express or implied. No variation or modification of this Note, or any waiver of any of its provisions or conditions, shall be valid unless in writing and signed by an authorized representative of Maker and Payee. Any such waiver, consent, modification or change shall be effective only in the specific instance and for the specific purpose given. Any provision in this Note or any Security Agreement which is in conflict with any statute, law or applicable rule shall be deemed omitted, modified or altered to conform thereto.

Without limiting the foregoing, Debtor shall cooperate and do all acts deemed necessary or advisable by Secured Party to continue in Secured Party a perfected first security interest in the Collateral, and shall obtain and furnish to Secured Party any subordinations, releases, landlord waivers, lessor waivers, mortgagee waivers, or control agreements, and similar documents as may be from time to time requested by, and in form and substance satisfactory to, Secured Party.

Debtor ratifies its prior authorization for Secured Party to file financing statements and amendments thereto describing the Collateral and containing any other information required by the Uniform Commercial Code if filed prior to the date hereof. (c) Debtor shall indemnify and defend the Secured Party, its successors and assigns, and their respective directors, officers and employees, from and against all claims, actions and suits (including, without limitation, related attorney fees) of any kind whatsoever arising, directly or indirectly, in connection with any of the Collateral.

7. DEFAULT AND REMEDIES. (a) Debtor shall be in default under this Agreement and each of the other Debt Documents if: (i) Debtor breaches its obligation to pay when due any installment or other amount due or coming due under any of the Debt Documents; (ii) Debtor, without the prior written consent of Secured Party, attempts to or does sell, rent, lease, license, mortgage, grant a security interest in, or otherwise transfer or encumber (except for Permitted Liens) any of the Collateral; (iii) Debtor breaches any of its insurance obligations under Section 4; (iv) Debtor breaches any of its other obligations under any of the Debt Documents and fails to cure that breach within thirty (30) days after written notice from Secured Party; (v) Any warranty, representation or statement made by Debtor in any of the Debt Documents or otherwise in connection with any of the Indebtedness shall be false or misleading in any material respect; (vi) Any of the Collateral is subjected to attachment, execution, levy, seizure or confiscation in any legal proceeding or otherwise, or if any legal or administrative proceeding is commenced against Debtor or any of the Collateral, which in the good faith judgment of Secured Party subjects any of the Collateral to a material risk of attachment, execution, levy, seizure or confiscation and no bond is posted or protective order obtained to negate such risk; (vii) Debtor breaches or is in default under any other agreement between Debtor and Secured Party; (viii) Debtor or any guarantor or other obligor for any of the Indebtedness (collectively "Guarantor") dissolves, terminates its existence, becomes insolvent or ceases to do business as a going concern; (ix) If Debtor or any Guarantor is a natural person, Debtor or any such Guarantor dies or becomes incompetent; (x) A receiver is appointed for all or of any part of the property of Debtor or any Guarantor, or Debtor or any Guarantor makes any assignment for the benefit of creditors; (xi) Debtor or any Guarantor files a petition under any bankruptcy, insolvency or similar law, or any such petition is filed against Debtor or any Guarantor and is not dismissed within forty-five (45) days; or (xii) Debtor's improper filing of an amendment or termination statement relating to a filed financing statement describing the Collateral. (b) If Debtor is in default the Secured Party, at its option, may declare any or all of the Indebtedness to be immediately due and payable, without demand or notice to Debtor or any Guarantor. The accelerated obligations and liabilities shall bear interest (both before and after any judgment) until paid in full at the lower of eighteen percent (18%) per annum or the maximum rate not prohibited by applicable law. (c) After default, Secured Party shall have all of the rights and remedies of a Secured Party under the Uniform Commercial Code, and under any other applicable law. Without limiting the foregoing, Secured Party shall have the right to (i) notify any account debtor of Debtor or any obligor on any instrument which constitutes part of the Collateral to make payment to the Secured Party, (ii) with or without legal process, enter any premises where the Collateral may be and take possession of and remove the Collateral from the premises or store it on the premises, (iii) sell the Collateral at public or private sale, in whole or in part, and have the right to bid and purchase at said sale, or (iv) lease or otherwise dispose of all or part of the Collateral, applying proceeds from such disposition to the obligations then in default. If requested by Secured Party, Debtor shall promptly assemble the Collateral and make it available to Secured Party at a place to be designated by Secured Party which is reasonably convenient to both parties. Secured Party may also render any or all of the Collateral unusable at the Debtor's premises and may dispose of such Collateral on such premises without liability for rent or costs. Any notice that Secured Party is

required to give to Debtor under the Uniform Commercial Code of the time and place of any public sale or the time after which any private sale or other intended disposition of the Collateral is to be made shall be deemed to constitute reasonable notice if such notice is given to the last known address of Debtor at least five (5) days prior to such action. (d) Proceeds from any sale or lease or other disposition shall be applied: first, to all costs of repossession, storage, and disposition including without limitation attorneys', appraisers', and auctioneers' fees; second, to discharge the obligations then in default; third, to discharge any other Indebtedness of debtor to Secured Party, whether as obligor, endorser, guarantor, surety or indemnitor; fourth, to expenses incurred in paying or settling liens and claims against the Collateral; and lastly, to Debtor, if there exists any surplus. Debtor shall remain fully liable for any deficiency. (e) Debtor agrees to pay all reasonable attorneys' fees and other costs incurred by Secured Party in connection with the enforcement, assertion, defense or preservation of Secured Party's rights and remedies under this Agreement, or if prohibited by law, such lesser sum as may be permitted. Debtor further agrees that such fees and costs shall constitute Indebtedness. (f) Secured Party's rights and remedies under this Agreement or otherwise arising are cumulative and may be exercised singularly or concurrently. Neither the failure nor any delay on the part of the Secured Party to exercise any right, power or privilege under this Agreement shall operate as a waiver, nor shall any single or partial exercise of any right, power or privilege preclude any other or further exercise of that or any other right, power or privilege. SECURED PARTY SHALL NOT BE DEEMED TO HAVE WAIVED ANY OF ITS RIGHTS UNDER THIS AGREEMENT OR UNDER ANY OTHER AGREEMENT, INSTRUMENT OR PAPER SIGNED BY DEBTOR UNLESS SUCH WAIVER IS EXPRESSED IN WRITING AND SIGNED BY SECURED PARTY. A waiver on any one occasion shall not be construed as a bar to or waiver of any right or remedy on any future occasion. (g) DEBTOR AND SECURED PARTY UNCONDITIONALLY WAIVE THEIR RIGHTS TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING OUT OF THIS AGREEMENT, ANY OF THE OTHER DEBT DOCUMENTS, ANY OF THE INDEBTEDNESS SECURED HEREBY, ANY DEALINGS BETWEEN DEBTOR AND SECURED PARTY RELATING TO THE SUBJECT MATTER OF THIS TRANSACTION OR ANY RELATED TRANSACTIONS, AND/OR THE RELATIONSHIP THAT IS BEING ESTABLISHED BETWEEN DEBTOR AND SECURED PARTY. THE SCOPE OF THIS WAIVER IS INTENDED TO BE ALL ENCOMPASSING OF ANY AND ALL DISPUTES THAT MAY BE FILED IN ANY COURT. THIS WAIVER IS IRREVOCABLE. THIS WAIVER MAY NOT BE MODIFIED EITHER ORALLY OR IN WRITING. THE WAIVER ALSO SHALL APPLY TO ANY SUBSEQUENT AMENDMENTS, RENEWALS, SUPPLEMENTS OR MODIFICATIONS TO THIS AGREEMENT, ANY OTHER DEBT DOCUMENTS, OR TO ANY OTHER DOCUMENTS OR AGREEMENTS RELATING TO THIS TRANSACTION OR ANY RELATED TRANSACTION. THIS AGREEMENT MAY BE FILED AS A WRITTEN CONSENT TO A TRIAL BY THE COURT. 8. MISCELLANEOUS. (a) This Agreement, any Note and/or any of the other Debt Documents may be assigned, in whole or in part, by Secured Party without notice to Debtor, and Debtor agrees not to assert against any such assignee, or assignee's assigns, any defense, set-off, recoupment claim or counterclaim which Debtor has or may at any time have against Secured Party for any reason whatsoever. Debtor agrees that if Debtor receives written notice of an assignment from Secured Party, Debtor will pay all amounts payable under any assigned Debt Documents to such assignee or as instructed by Secured Party. Debtor also agrees to confirm in writing receipt of the notice of assignment as may be reasonably requested by Secured Party or assignee. (b) All notices to be given in connection with this Agreement shall be in writing, shall be addressed to the parties at their respective addresses set forth in this Agreement (unless and until a different address may be specified in a written notice to the other party), and shall be deemed given (i) on the date of receipt if delivered in hand or by facsimile transmission, (ii) on the next business day after being sent by express mail, and (iii) on the fourth business day after being sent by regular, registered or certified mail. As used herein, the term "business day" shall mean and include any day other than Saturdays, Sundays, or other days on which commercial banks in New York, New York are required or authorized to be closed.

(d) Time is of the essence of this Agreement. This Agreement shall be binding, jointly and severally, upon all parties described as the "Debtor" and their respective heirs, executors, representatives, successors and assigns, and shall inure to the benefit of Secured Party, its successors and assigns. (e) This Agreement and its Collateral Schedules constitute the entire agreement between the parties with respect to the subject matter of this Agreement and supersede all prior understandings (whether written, verbal or implied) with respect to such subject matter. THIS AGREEMENT AND ITS COLLATERAL SCHEDULES SHALL NOT BE CHANGED OR TERMINATED ORALLY OR BY COURSE OF CONDUCT, BUT ONLY BY A WRITING SIGNED BY BOTH PARTIES. Section headings contained in this Agreement have been included for convenience only, and shall not affect the construction or interpretation of this Agreement. (f) This Agreement shall continue in full force and effect until all of the Indebtedness has been indefeasibly paid in full to Secured Party or its assignee. The surrender, upon payment or otherwise, of any Note or any of the other documents evidencing any of the Indebtedness shall not affect the right of Secured Party to retain the Collateral for such other Indebtedness as may then exist or as it may be reasonably contemplated will exist in the future. This Agreement shall automatically be reinstated if Secured Party is ever required to return or restore the payment of all or any portion of the Indebtedness (all as though such payment had never been made). (g) THIS AGREEMENT AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES HEREUNDER SHALL IN ALL RESPECTS BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH, THE INTERNAL LAWS OF THE STATE OF CONNECTICUT (WITHOUT REGARD TO THE CONFLICT OF LAWS PRINCIPLES OF SUCH STATE), INCLUDING ALL MATTERS OF CONSTRUCTION, VALIDITY AND PERFORMANCE, REGARDLESS OF THE LOCATION OF THE EQUIPMENT. IN WITNESS WHEREOF, Debtor and Secured Party, intending to be legally bound hereby, have duly executed this Agreement in one or more counterparts, each of which shall be deemed to be an original, as of the day and year first aforesaid.

      1. CREATION OF SECURITY INTEREST.

      This Section I is hereby amended and replaced with the following:

      obligations and liabilities (such Notes, debts, obligations and
      liabilities are called the "INDEBTEDNESS")."

      3. COLLATERAL.

      Subsection (b) is hereby amended and replaced with the following:

      "(b) Debtor shall (i) use the Collateral only in its trade or business,
      (ii) maintain all of the Collateral in good operating order and repair,
      normal wear and tear excepted, (iii) use and maintain the Collateral in a
      manner that would not violate the manufacturers recommendations and all
      applicable laws, and (iv) keep all of the Collateral free and clear of all
      liens, claims and encumbrances (except for Permitted Liens)."

      4. INSURANCE.

      Subsection (b) is hereby amended and replaced with the following:

      "(b) Debtor agrees to keep the Collateral insured against loss or damage
      by fire and extended coverage perils, theft, burglary, and for any or all
      Collateral which are vehicles, for risk of loss by collision, and if
      requested by Secured Party, against such other risks as Secured Party may
      reasonably require. The insurance coverage shall be in an amount no less
      than the full replacement value of the Collateral, and deductible amounts,
      insurers and policies shall be acceptable to Secured Party. Debtor shall
      deliver to Secured Party policies or certificates of insurance evidencing
      such coverage. Each policy shall name Secured Party as a loss payee, shall
      provide for coverage to Secured Party regardless of the breach by Debtor
      of any warranty or representation made therein, shall not be subject to
      coinsurance, and shall provide that coverage may not be canceled or
      altered by the insurer except upon thirty (30) days prior written notice
      to Secured Party. Debtor appoints Secured Party as its attorney-in-fact to
      make proof of loss, claim for insurance and adjustments with insurers, and
      to receive payment of and execute or endorse all documents, checks or
      drafts in connection with insurance payments. Secured Party shall not act
      as Debtor's attorney-in-fact unless Debtor is in default. So long as
      Debtor is not in default under the Agreement, proceeds of insurance less
      than $50,000 shall be applied at the Debtor's option, to repair or replace
      the Collateral or to reduce any of the Indebtedness, otherwise insurance
      proceeds shall be applied, at the option of Secured Party, to repair or
      replace the Collateral or to reduce any of the Indebtedness."

5. REPORTS. Subsection (b) is hereby amended and replaced with the following: "(b) Debtor will deliver to Secured Party financial statements as follows. If Debtor is a privately held company, then Debtor agrees to provide monthly financial statements, certified by Debtor's president or chief financial officer including a balance sheet, statement of operations and cash flow statement within 30 days of each month end and its complete audited annual financial statements, certified by a recognized firm of certified public accountants, within 120 days of fiscal year end or at such time as Debtor's Board of Directors receives the audit. If Debtor is a publicly held company, then Debtor agrees to provide quarterly unaudited statements and annual audited statements, certified by a recognized firm of certified public accountants, within 10 days after the statements are provided to the Securities and Exchange Commission ("SEC"). All such statements are to be prepared using generally accepted accounting principles ("GAAP") and, if Debtor is a publicly held company, are to be in compliance with SEC requirements." 7. DEFAULT AND REMEDIES. Subsection (a) is hereby amended and replaced with the following: "(a) Debtor shall be in default under this Agreement and each of the other Debt Documents if. (i) Debtor breaches its obligation to pay when due any installment or other amount due or coming due under any of the Debt Documents; (ii) Debtor, without the prior written consent of Secured Party, attempts to or does sell, rent, lease, license, mortgage, grant a security interest in, or otherwise transfer or encumber (except for Permitted Liens) any of the Collateral; (iii) Debtor breaches any of its insurance obligations under Section 4; (iv) Debtor breaches any of its other obligations under any of the Debt Documents and fails to cure that breach within thirty (30) days after written notice from Secured Party; (v) Any warranty, representation or statement made by Debtor in any of the Debt Documents or otherwise in connection with any of the Indebtedness shall be false or misleading in any material respect; (vi) Any of the Collateral is subjected to attachment, execution, levy, seizure or confiscation in any legal proceeding or otherwise, or if any legal or administrative proceeding is commenced against Debtor or any of the Collateral, which in the good faith judgment of Secured Party subjects any of the Collateral to a material risk of attachment, execution, levy, seizure or confiscation and no bond is posted or protective order obtained to negate such risk; (vii) Debtor breaches or is in default under any other agreement between Debtor and Secured Party; (viii) Debtor or any guarantor or other obligor for any of the Indebtedness (collectively "GUARANTOR") dissolves, terminates its existence, becomes insolvent or ceases to do business as a going concern; (ix) If Debtor or any Guarantor is a natural person, Debtor or any such Guarantor dies or becomes incompetent;

(x) A receiver is appointed for all or of any part of the property of Debtor or any Guarantor, or Debtor or any Guarantor makes any assignment for the benefit of creditors; (xi) Debtor or any Guarantor files a petition under any bankruptcy, insolvency or similar law, or any such petition is filed against Debtor or any Guarantor and is not dismissed within forty-five (45) days; (xii) Debtor's improper filing of an amendment or termination statement relating to a filed financing statement describing the Collateral; or (xiii) There is a material adverse change in the Debtor's financial condition, other than changes in cash reserves in the ordinary course of business on a stand alone basis, as determined solely by Secured Party." (xiv) At any time during the term of this Agreement Debtor sells more than 50% of its equity interest in the company to another corporation or business or all or substantially all of its assets without Secured Party's prior written consent. TERMS USED, BUT NOT OTHERWISE DEFINED HEREIN SHALL HAVE THE MEANINGS GIVEN TO THEM IN THE AGREEMENT. EXCEPT AS EXPRESSLY AMENDED HEREBY, THE AGREEMENT SHALL REMAIN IN FULL FORCE AND EFFECT. IF THERE IS ANY CONFLICT BETWEEN THE PROVISIONS OF THE AGREEMENT AND THIS AMENDMENT, THEN THIS AMENDMENT SHALL CONTROL. IN WITNESS WHEREOF, the parties hereto have executed this Amendment simultaneously with the Agreement by signature of their respective authorized representative set forth below.
