Nabi Biopharmaceuticals


PART I

ITEM 1. BUSINESS

OVERVIEW

Nabi Biopharmaceuticals discovers, develops, manufactures and markets products that power the immune system to help people with serious, unmet medical needs. We have a broad product portfolio and significant research capabilities focused on developing and commercializing novel vaccines and antibody-based biopharmaceutical products that prevent and treat infectious, autoimmune and addictive diseases, such as hepatitis B, hepatitis C and Staphylococcus aureus infections, immune thrombocytopenia purpura (“ITP”) and nicotine addiction. We have four marketed products, Nabi-HB® [Hepatitis B Immune Globulin (Human)] for the prevention of hepatitis B infections, WinRho SDF® [Rho(D) Immune Globulin Intravenous (Human)] for the treatment of acute, chronic and HIV-related ITP, Autoplex® T [Anti-Inhibitor Coagulant Complex, Heat Treated] and Aloprim™ [(Allopurinol sodium) for injection]. We have a significant clinical trials program including clinical trials of our lead investigational products, StaphVAX® (Staphylococcus aureus Polysaccharide Conjugate Vaccine), Altastaph™ [Staphylococcus aureus Immune Globulin (Human)], Civacir™ [Hepatitis C Immune Globulin (Human)], and NicVAX™ (Nicotine Conjugate Vaccine). We have a state-of-the-art fractionation facility for the manufacture of Nabi-HB and our investigational antibody products and for contract manufacturing. Further, we also collect specialty and non-specific antibodies for use in our products as well as to supply pharmaceutical and diagnostic customers for the subsequent manufacture of their products.

PRODUCTS

Currently Marketed Biopharmaceutical Products

Sales of our biopharmaceutical products, Nabi-HB, WinRho SDF, Autoplex T and Aloprim, totaled $89.5 million in 2002 compared to $73.4 million in 2001. In 2002, biopharmaceutical products accounted for 46% of our sales and 86% of our gross margin. Each of our four currently marketed biopharmaceutical products is described below:

Nabi-HB® [Hepatitis B Immune Globulin (Human)]

Sales of Nabi-HB were $41.2 million in 2002 compared to $30.3 million in 2001.

The hepatitis B virus (“HBV”) is a major health concern globally. According to the World Health Organization (“WHO”) data from 2000, of the 2 billion people who have been infected with HBV, more than 350 million have chronic infections. The Hepatitis B Foundation currently estimates that one out of 20 people in the U.S. has been infected with HBV, and reports that HBV is 100 times more infectious than the human immunodeficiency virus (“HIV”). The U.S. Center for Disease Control (“CDC”) currently estimates that in the U.S. alone there are an estimated 1.25 million chronic hepatitis B carriers, 78,000 new hepatitis B infections per year, and 5,000 individuals who die annually from hepatitis B or its complications. Approximately half of new hepatitis B infections are caused by sexual exposures. The most recent CDC estimates, measured in 1991 dollars, are that HBV costs the U.S. economy at least $700 million annually in medical expenses and lost work time.

Nabi-HB is a human polyclonal antibody product indicated to prevent hepatitis B following sexual or other exposure, including needle sticks and transmission from hepatitis B antigen-positive mothers to their newborns. In October 2001, we received approval from the U.S. Food and Drug Administration (“FDA”) to manufacture Nabi-HB in our biopharmaceutical manufacturing facility in Boca Raton, Florida and we began manufacturing all of our requirements of Nabi-HB at this facility in the fourth quarter of 2001. As the initial phase of our international sales strategy for Nabi-HB, during 2002 we entered into four

international distribution agreements that are expected to introduce this product into Turkey, Singapore and Malaysia over the coming two years as well as in up to forty-three countries on a named patient basis through our distribution agreement with IDIS World Medicines. Plans are underway to obtain regulatory approval for Nabi-HB to be introduced into Europe and other developed markets.

In November 2002, we submitted a Biologics License Application (“BLA”) to the FDA for the use of an intravenous (“IV”) formulation of Nabi-HB to prevent liver transplant patients from suffering re-infection with HBV. Nabi-HB® Intravenous [Hepatitis B Immune Globulin (Human)] has received Orphan Drug Designation from the FDA. In January 2003, we received notification that the FDA had accepted our IV BLA for priority review. A priority review means that the FDA commits to responding to this BLA within six months, instead of the statutorily required ten months.

WinRho SDF® [Rho(D) Immune Globulin Intravenous (Human)]

Sales of WinRho SDF were $34.0 million in 2002 compared to $34.8 million in 2001.

ITP is an autoimmune disease that manifests itself in abnormally low platelet levels (thrombocytopenia) resulting in excessive bleeding. The term “purpura” refers to the appearance of purple patches on the body caused by bleeding into the skin and mucous membranes. In ITP, the body’s immune system produces antibodies that attach to platelets causing them to be removed from circulation, primarily by the spleen. Because platelets are required for blood clotting, as platelet counts decrease, the incidence of bleeding episodes increase. In certain cases, such as severe trauma or spontaneous intracranial hemorrhage, the bleeding can be life threatening. The Platelet Disorder Support Association currently estimates that in the U.S., up to 125 cases per million people (children and adults) develop ITP each year. In children, the disease is usually acute at onset and is often resolved with treatment in six months. In adult ITP, the onset is gradual and rarely resolves itself without treatment. Additionally, ITP is more common in females than males. ITP can occur as either a primary disease or secondary to another underlying disease such as HIV or Lupus. In 2002, as published in Blood Reviews, chronic thrombocytopenia is currently estimated to occur in about 10% of HIV-infected patients and in about a third of patients with AIDS.

WinRho SDF is a human polyclonal antibody product approved and marketed for the treatment of ITP. We began exclusive marketing of WinRho SDF in the U.S. in mid-1995 under a license and distribution agreement with Cangene Corporation (“Cangene”) focused on the ITP market. Under our agreement with Cangene, which ends in March 2005, Cangene manufactures WinRho SDF for us. We are currently conducting two clinical studies under Investigational New Drug Applications (“IND”) involving WinRho SDF, (1) a comparison of WinRho SDF versus IVIG for the treatment of ITP, and (2) an evaluation of WinRho SDF in the treatment of ITP during pregnancy. See also “Strategic Alliances,” “Supply and Manufacturing” and “Government and Industry Regulation — Orphan Drug Act.”

Orphan Drug Designation for WinRho SDF for the treatment of ITP expired in March 2002.

Autoplex® T [Anti-Inhibitor Coagulant Complex, Heat Treated]

Hemophilia A is a blood clotting disorder characterized by a lack of functional coagulation factor VIII. Physicians typically treat hemophilia A by replacing the deficient factor with either recombinant clotting factor VIII or human factor VIII. In most cases, replacement therapy is effective in stopping bleeding episodes. However, the treatment of hemophilia A is complicated when an inhibitor or antibody is produced in response to outside sources of factor VIII. These antibodies neutralize infused factor VIII, rendering the patient at risk for excessive bleeding episodes. In 1998, the CDC estimated that there were approximately 13,000 hemophilia A patients in the U.S. As published in a 1995 publication, Inhibitors: A Complicating Factor, approximately 10-20% of them suffer from the production of inhibitors to outside sources of factor VIII.

Autoplex T is a coagulation complex used to treat patients who have developed inhibitors to factor VIII. We acquired exclusive rights to distribute Autoplex T in the U.S., Canada and Mexico from Baxter

Healthcare Corporation (“Baxter”) in May 1997. Our current agreement to distribute Autoplex T expires in May 2003, although we believe it will be extended until May 2004. Baxter supplies Autoplex T to us. See also “Strategic Alliances” and “Supply and Manufacturing.”

Aloprim[(Allopurinol sodium) for injection]

Aloprim is indicated for the treatment of chemotherapy-induced hyperuricemia in patients with leukemia, lymphoma, or solid organ tumors. Complications associated with chemotherapy-induced hyperuricemia in these patients include renal failure. Aloprim is targeted to those patients who develop chemotherapy-induced hyperuricemia and are not treatable by oral therapies. Based on 2002 data from the American Cancer Society, there are approximately 90,000 patients annually suffering from leukemia and lymphoma in the U.S. that could potentially be at risk for developing chemotherapy-induced hyperuricemia. We acquired certain rights to distribute Aloprim from DSM Pharmaceuticals (formerly Catalytica Pharmaceuticals) (“DSM”) in June 1999 and currently have the exclusive right to distribute Aloprim in the U.S. and Canada. Our current agreement with DSM expires in 2004. Under the terms of the distribution agreement with DSM, we have the option to acquire the rights to manufacture and distribute Aloprim from DSM prior to expiration of the agreement. DSM is obligated to supply Aloprim to us through the expiration date of the distribution agreement. Aloprim has received Orphan Drug Designation for treatment of chemotherapy-induced hyperuricemia through May 2003. See also “Strategic Alliances”, “Supply and Manufacturing” and “Governmental and Industry Regulation — Orphan Drug Act.”

Currently Marketed Antibodies and Intermediate Products

In September 2001, we sold the operating assets of a majority of our antibody collection centers and our testing laboratory for $156.3 million in cash. By retaining nine antibody collection centers, we expect to generate sufficient raw materials for the manufacture of our own antibody-based biopharmaceutical products in our Boca Raton, Florida manufacturing facility. We also supply pharmaceutical and diagnostic customers with specialty and non-specific antibodies for the manufacture of their products.

Sales of our antibody products totaled $106.5 million in 2002 compared to $161.4 million in 2001. The decrease was expected due to the sale of the majority of our antibody collection business and testing laboratory in September 2001. In 2002, antibody products accounted for 54% of our sales and 14% of our gross margin. As we are able to achieve licensure for antibody-based biopharmaceutical products in our research and development pipeline, we anticipate a strategic shift in our antibody segment of converting production of non-specific antibodies into the production of specialty antibodies which we will use to manufacture our own antibody-based biopharmaceutical products. Currently, specialty antibodies produced in our antibody collection centers are used in the production of Nabi-HB and WinRho SDF. Our specialty antibodies and non-specific antibody products are described below.

Specialty Antibodies

Specialty antibody products contain high concentrations of a specific antibody and are used primarily to manufacture antibody-based biopharmaceutical products to treat chronic immune disorders and to prevent and treat viral and bacterial diseases as well as to develop diagnostic products.

We identify potential specialty antibody donors through screening and testing procedures. We also have developed FDA-licensed programs to vaccinate potential donors to stimulate their production of specific antibodies. We believe that our antibody collection capabilities, our operational expertise in donor immunization programs, our clinical and medical experience in conducting clinical trials under IND, and our access to a diverse antibody donor base provides us with a strategic advantage over competitors in our ability to produce specialty antibodies.

Our principal specialty antibody products include:

  Hepatitis B Antibodies. Antibodies to HBV are used to manufacture hepatitis B immune globulin therapeutic products that provide passive immunity against HBV. We are strategically committed to

    utilizing our collection of these antibodies to HBV to manufacture Nabi-HB, our hepatitis B antibody-based biopharmaceutical product.
 
  RhoD Antibodies. Antibodies to RhoD antigen (anti-D) have long been used to prevent Rho(D) isoimmunization in Rh-negative women and subsequent hemolytic disease (blue baby disease) in Rh-positive infants. These antibodies are also used to treat ITP in children and adults. Antibodies to RhoD antigen are used in the manufacture of WinRho SDF, our antibody-based biopharmaceutical product for the treatment of ITP.
 
  Tetanus Antibodies. Antibodies to tetanus toxin are used by our customers to produce therapeutic products to provide short-term protective immunity to patients exposed to tetanus.
 
  Cytomegalovirus (“CMV”) Antibodies. Antibodies to CMV are supplied to manufacturers to enhance intravenous immune globulin (“IVIG”) products and to produce CMV-specific immune globulin therapeutic products.
 
  Rabies Antibodies. Antibodies to rabies are used by our customers to make therapeutic products that provide short-term protective antibody-based immunity to patients exposed to the rabies virus.
 
  Diagnostic Products and Services. We opportunistically commercialize and manufacture control reagents and specialty antibody-based products for use by in-vitro diagnostic manufacturers, regulatory agencies, testing laboratories, and diagnostic distributors.

Sales of specialty antibodies were $32.7 million in 2002 and $46.8 million in 2001. Specialty antibody sales decreased during 2002, due primarily to the sale of the majority of our antibody collection business and testing laboratory in September 2001.

Non-specific Antibodies

Our nine FDA licensed antibody collection centers also supply non-specific human antibodies from normal healthy donors to our customers in the pharmaceutical and diagnostic industries.

Although non-specific antibodies lack high levels of antibodies to specific antigens, such antibodies are used by our customers to manufacture standard IVIG, a product used to fight infections, and in the treatment of several conditions, including bone marrow transplantation, B-cell chronic lymphocytic leukemia, hypogammaglobulinemia, Kawasaki syndrome and other chronic immune deficiencies.

In 2002, we derived sales of $73.8 million from sales of non-specific antibodies as compared to 2001 levels of $114.5 million. Non-specific antibody sales have decreased in 2002 from 2001 as a result of the sale of the majority of the antibody collection business and testing laboratory in September 2001. Non-specific antibody sales include shipments to a single customer under a supply contract that expires in May 2003, which was retained by us following the sale of the majority of the antibody collection business and testing laboratory in September 2001. The purchaser of the majority of the antibody collection business and testing laboratory continues to supply us with non-specific antibodies which we did not collect at our centers, to fulfill this obligation at the selling price under this contract. Because we retain the risk of credit loss with this customer, we record revenues but no margin on these sales. Such sales totaled $55.6 million in 2002. In 2002, sales of non-specific antibodies collected at our retained antibody collection centers totaled $18.2 million.

Gram-positive Infections Program

Epidemiology

According to current estimates from the CDC, more than two million patients in the U.S. each year contract an infection as a result of exposure to a pathogen while receiving healthcare in a hospital. Within our nation’s 5,400 acute care hospitals, S. aureus is one of the three leading causes of hospital-acquired bloodstream infections, with a crude mortality rate of 25%. With its capacity to cause serious complications and its increasing antibiotic-resistance, S. aureus has become a critically dangerous pathogen. S. aureus can spread from the blood (bacteremia), to the bones (osteomyelitis), or the inner lining of the heart and its valves (endocarditis), or cause abscesses in internal organs such as the lungs and kidneys. Patients who are most at risk for these infections include surgical patients, trauma or burn victims, newborns whose immune systems are not yet developed and people with chronic illnesses such as chronic skin diseases, diabetes, cancer and lung diseases or kidney diseases. People whose immune systems are suppressed due to disease, drugs or radiation therapy also are more susceptible to these bacterial infections.

In 1997, the Lewin Group, an independent consulting group, published data from a 1995 study on the incidence, deaths and direct medical costs of S. aureus infections in hospitalized patients in the New York City metropolitan area. The report found that the total direct medical costs incurred as a result of S. aureus infections was estimated at $32,110 per patient (in 1995 dollars). In addition, S. aureus associated hospitalizations resulted in more than twice the length of hospitalization, twice the deaths and twice the medical costs compared to an average hospital stay.

Staphylococcal infections are difficult to treat because the bacteria that cause them are highly virulent (severe) and resistant to many currently available antibiotics.

Table of Contents

The rise of antibiotic resistance has markedly curtailed options for treating Gram-positive bacterial infections. The first penicillin-resistant strains of S. aureus were identified in 1944, and by the late 1950’s, approximately half of S. aureus infections were of this type. Methicillin-resistant strains were identified in 1961, just one year after the introduction of this antibiotic. According to the National Nosocomial Infections Surveillance System, in large, urban U.S. hospitals, 53.5% of S. aureus pathogens associated with nosocomial infections in ICU patients are resistant to methicillin. In 1996, the CDC reported that the first S. aureus strains with notably reduced sensitivity to vancomycin (so-called, vancomycin intermediate sensitive S. aureus — VISA strains) were discovered in Japan. In July of 2002, the first case of S. aureus fully resistant to vancomycin (VRSA) was reported by the CDC. This VRSA infection occurred in a 40-year-old, diabetic, hemodialysis patient in the U.S.

Dual Approach to Gram-positive bacterial infections

We are using a dual approach to developing products to combat Gram-positive bacterial infections: StaphVAX and Altastaph.

StaphVAX, an investigational polysaccharide conjugate vaccine, is a novel approach to the prevention of S. aureus infections. This product is designed for use in patients who are immune competent and who have the time and ability to respond to a vaccination by making their own antibodies (usually about two weeks) before they are at increased risk for infection (e.g. an elective surgery patient). StaphVAX targets S. aureus serotypes, type 5 and type 8, which are responsible for approximately 85% of S. aureus infections. While traditional vaccines typically target pediatric populations or healthy adults and entail mass vaccination, StaphVAX will be targeted to adult patients who are hospitalized, chronically ill or in a long-term care facility and therefore at high risk of developing a S. aureus infection. StaphVAX is intended to stimulate a patient’s immune system to produce antibodies to S. aureus that provide active, long-term protection from the bacteria. After receiving the vaccine, patients generate antibodies specific to S. aureus (serotypes 5 and 8) that may last for several years in non-immune compromised patients and almost a year in patients with partially compromised immune systems. Based on results from clinical studies, these levels of antibody appear to provide protection against S. aureus bacteremia, which can lead to potentially life-threatening and costly infections.

StaphVAX contains surface polysaccharides found in the outer coating (capsular polysaccharide or CP) of S. aureus serotypes 5 and 8. The polysaccharide molecules are linked, or conjugated, in the vaccine with a non-toxic, carrier protein derived from the bacteria Pseudomonas aeruginosa. Once given the vaccine, the patients’ immune systems produce proteins, called antibodies, which bind to S. aureus on subsequent exposure to the bacteria. These antibodies help the immune system to identify the staph bacteria while it is still in the blood (bacteremia) and eliminate it. Since these antibodies bind to several sites on the bacteria’s surface polysaccharides, we believe that the bacteria will be unable to develop resistance to the antibodies as it has to antibiotics.

Altastaph is an investigational human polyclonal antibody product being developed to prevent S. aureus infections in patients who are at immediate risk of infection or who cannot produce their own antibodies when given a vaccine. Some examples of patients that could benefit from Altastaph include low birth weight newborns, trauma patients and emergency surgical patients. We are also exploring the potential to use Altastaph to treat an existing infection. Altastaph is made from purified antibodies from donors who have been immunized with StaphVAX and who have responded to the vaccine by generating high levels of antibodies to the S. aureus bacteria. Altastaph can be provided to a patient by infusion. Given the circulating half-life of such antibodies, the protection provided by a single injection of Altastaph is expected to last a number of weeks, and can be potentially extended by giving repeated doses.

StaphVAX® (Staphylococcus aureus Polysaccharide Conjugate Vaccine)

StaphVAX is being developed for the 12 million patients estimated to be at high risk of infection and who are able to respond to a vaccine by producing their own antibodies. Potential at-risk patient populations who may benefit from the use of StaphVAX include: (a) patients such as the elderly and those suffering chronic diseases including end stage renal disease (“ESRD”), congestive heart failure, chronic

10


Table of Contents

obstructive pulmonary disease and diabetics who are expected to have long stays in medical or extended care facilities; (b) patients undergoing planned surgery who can be vaccinated in advance and in whom staph infections can have serious consequences; (c) prosthetic surgery and vascular graft patients who are at long-term risk of staph infections due to their implants; (d) chronic osteomyelitis patients, spinal cord injury and spinal fusion patients; and (e) hematology/oncology patients. Infection rates in these high-risk populations range from 1-10% and, as shown by the 1997 Lewin Group study discussed above, S. aureus infections result in longer hospital stays, higher death rates and significantly higher medical costs.

StaphVAX is based on patented vaccine technology in-licensed from the Public Health Service (“PHS”)/ NIH. See also “Strategic Alliances.” In late 2000, we completed a Phase III placebo controlled clinical trial for StaphVAX in hemodialysis patients with ESRD. We targeted this patient population because of the relatively high infection rate and because they are at long-term risk of infection and could maximally benefit from the protection that a vaccine may afford. A total of 1,804 patients were included in the study. Half the enrolled patients were vaccinated with StaphVAX and half received a placebo. The clinical trial population was followed for a year to evaluate vaccine safety and S. aureus infection rates. The results of the trial showed that a single injection of StaphVAX was safe and reduced the incidence of S. aureus bacteremia by almost 60% through 10 months post-vaccination. The reduction in bacteremia one year after vaccination was 26%. Side effects in those patients receiving the vaccine were generally mild to moderate and generally resolved within 36 to 48 hours following vaccination. The most commonly occurring side effect was minor pain at the intramuscular injection site. The results in ESRD patients are especially relevant because these patients are severely immune-compromised, and therefore, generally respond poorly to vaccines. Based upon previous clinical studies in normal, healthy volunteers, immune-competent patients who are at risk for S. aureus infections are expected to respond more favorably with higher levels of antibody to StaphVAX than ESRD patients. The significance of the results of this trial was confirmed by publication in the New England Journal of Medicine in February 2002.

To build on the results of the Phase III trial, we initiated a booster trial in 2001, giving a second dose of StaphVAX to 77 hemodialysis patients who received an initial dose of the vaccine in the Phase III trial completed in 2000. The booster trial was designed to provide an indication that patients at long-term risk could respond to a booster dose of the vaccine. Results from the trial were reported in May 2002. The trial demonstrated that a booster dose of the vaccine given to previously vaccinated hemodialysis patients increased the concentration of the vaccine-specific antibodies against S. aureus. The trial results suggest that periodic booster doses of StaphVAX can be administered to increase and sustain antibody levels for patients at chronic risk of S. aureus infection. The average antibody concentrations reached after the booster vaccination were above what our scientists believe to be a protective level, although not as high as those following the first dose of vaccine. In addition, antibody levels decreased more gradually over time after the booster vaccination than following the initial dose.

Dow Biopharmaceutical Contract Manufacturing Services (formerly Collaborative BioAlliance) (“Dow”) is planned to be the commercial manufacturer for StaphVAX. During 2002, Dow successfully completed manufacture of the first clinical lot of vaccine at their facility. We plan to begin a clinical study to compare the immune system response (immunogenicity) to the Dow-manufactured vaccine with the response achieved in previous trials using the vaccine manufactured in our pilot plant. With good results, we would expect to begin a confirmatory Phase III clinical trial during the second half of 2003.

Because the reduction in infections in the initial Phase III trial was not statistically significant at the primary endpoint of the trial, twelve months post-vaccination, we have planned a confirmatory Phase III clinical trial for StaphVAX with primary efficacy endpoint at 8 months post-vaccination. The size of the trial will be increased to approximately 3,000 subjects to increase its statistical power. In the Phase III trial, we will also administer a booster dose eight months following the initial vaccination and subjects will be followed to track the reduction in infections monitored for an additional four to six months as secondary endpoints. After a series of productive discussions with the FDA, we submitted the final design for the agency’s review in February 2003.

Altastaph™ [Staphylococcus aureus Immune Globulin (Human)]

Altastaph is an investigational human polyclonal antibody product that contains high levels of specific antibodies against S. aureus serotypes 5 and 8. These antibodies are collected from normal healthy donors who have been vaccinated with StaphVAX at our antibody collection centers. The collected antibodies are purified into Altastaph at our biopharmaceutical manufacturing facility in Boca Raton, Florida. In contrast to StaphVAX, which is intended to provide long-term protection against S. aureus infection, Altastaph is being developed to provide short-term protection to patients at immediate risk of infection, or who are immunocompromised and cannot respond effectively to a vaccine. High-risk populations that could benefit from a product such as Altastaph include low birth weight newborns, trauma patients and emergency surgical patients. This type of protection or treatment may be cost-effective because antibodies in a single dose of Altastaph persist in the bloodstream for a number of weeks and can be available to provide protection for the entire risk period. We are also exploring the use of Altastaph as a therapeutic agent for use in patients with persistent S. aureus infections.

In 1999, we successfully completed a multi-dose safety and pharmacokinetic (the measure of the drug’s interaction in the body or “PK”) Phase I/II trial of Altastaph in low birth weight newborns that demonstrated its safety and PK at a variety of dosage levels. The PK analysis indicated that titers of the specific anti-staph antibodies are dose-related. Even the lowest dose (500 mg/kg) of Altastaph resulted in antibody titers that pre-clinical models and clinical trials with StaphVAX indicate may be protective against infection. A larger Phase II clinical trial of Altastaph in low birth weight newborns is planned to commence in 2003.

In 2002, we initiated a placebo controlled, blinded clinical trial at a number of clinical sites to evaluate the safety and PK of Altastaph in adults with S. aureus infections. Enrollment for this trial has commenced. As a therapeutic product, Altastaph may be expected to act synergistically, or additively, with antibiotics given the different mechanisms of these therapies.

Next Generation Products and Other Anti-Bacterial Vaccines in Development

We have also identified and patented an antigen (type 336) found on a serotype of S. aureus, that accounts for over 90% of non-type 5 and non-type 8 S. aureus clinical infections, or about 10-12% of all clinically significant S. aureus infections. We have identified, purified and characterized the type 336 antigen and have prepared a prototype conjugate vaccine that is capable of protecting animals from challenge with clinical isolates of the serotype. During 1998, we were issued a U.S. patent on the type 336 antigen. Included in the patent were claims relating to vaccines made from type 336 antigen and monoclonal and polyclonal antibodies reactive to the antigen. Patents for type 336 antigen and its use are being pursued worldwide. The second generation of StaphVAX and Altastaph is expected to contain type 336 antigen in addition to S. aureus types 5 and 8 antigens. This second-generation vaccine is expected to provide coverage for greater than 95% of all clinically significant S. aureus bacteria.

S. epidermidis and Enterococcus faecalis are the two other clinically significant Gram-positive bacteria that cause hospital-acquired infections. We intend to extend product coverage to these two Gram-positive bacteria in subsequent generations of StaphVAX and Altastaph. We have been issued two patents containing claims covering both a S. epidermidis vaccine and human polyclonal antibodies and have filed patent applications on selected enterococcal antigens. Prototypic S. epidermidis and enterococcal vaccines produced by us have been shown to induce antibodies that are protective in animal models and facilitate elimination of bacteria by the same type of immune system response as StaphVAX.

Anti-Viral Program:

Nabi-HB® Intravenous [Hepatitis B Immune Globulin (Human)]

In November 2002, we submitted a BLA to the FDA for the use of an IV formulation of Nabi-HB to prevent liver transplant patients from suffering re-infection

with HBV. Nabi-HB Intravenous has received Orphan Drug Designation from the FDA. In January 2003, we received notification that the FDA accepted our IV BLA for priority review. A priority review means that the FDA commits to responding to this BLA within six months, instead of the statutorily required ten months.

Civacir™ [Hepatitis C Immune Globulin (Human)]

Hepatitis C virus (“HCV”) has significant economic impact because it causes chronic infections in a large percentage of those infected and results in severe illness and death in later stages of the disease. Chronic HCV infection is a frequent cause of end-stage liver disease in North America and Europe and is present in approximately one third of patients undergoing liver transplants. Moreover, during surgery and in the period immediately following transplant surgery, these patients have no treatment options to prevent re-infection of the transplanted liver. Re-infection of the transplanted liver is almost universal within weeks to months after surgery and can occur within days of transplantation. HCV infection also contributes to frequent hospitalizations and failure of the transplanted liver when it occurs in transplant patients. The CDC currently estimates that there are approximately 2.7 million individuals in the U.S. chronically infected with HCV, and the WHO estimates 170 million individuals worldwide are infected with HCV.

Civacir is an experimental human polyclonal antibody product that contains antibodies to HCV. Pre-clinical studies indicate that Civacir contains antibodies that are neutralizing to HCV. We are developing Civacir for the prevention of HCV re-infection of transplanted livers in patients infected with HCV.

In 2000, we completed a series of animal studies of Civacir, using chimpanzees, in collaboration with the CDC under a Cooperative and Research Development Agreement. The results from these animal studies suggest that the elevated level of HCV-specific antibodies in serum maintained by multiple infusions of Civacir over a period of months is associated with prevention of acute hepatitis and the possible elimination of HCV antigen from liver cells after HCV infection. We have manufactured clinical lots of Civacir and plan to manufacture commercial lots of Civacir at our Boca Raton, Florida biopharmaceutical manufacturing facility upon licensure by the FDA of this product.

In September 2000, we signed a Clinical Trials Agreement for “Evaluation of the Safety and Pharmacokinetics of Hepatitis C Immune Globulin (Human), Civacir, in Liver Transplant Patients” with the NIAID.

In March 2002 under an IND, we commenced a Phase I/II trial of Civacir in HCV-positive liver transplant patients at six study sites in the U.S. This NIAID funded trial is a three-armed, randomized, controlled clinical study evaluating two dose levels of Civacir versus a control. In this trial we are also evaluating the safety of dosing patients with Civacir during and after transplant surgery. We will also evaluate the PK of HCV specific antibody in trial subjects following dosing, as well as HCV levels in the transplanted livers. Patients participating in the trial are being followed for six months post initial dosing. The results of this trial will help us determine the safety of Civacir in this patient population and define the efficacy markers that may be important in subsequent Phase II and III trials. In December 2002, we announced that the Civacir trial was fully enrolled and we anticipate reporting initial results from the trial in 2003. Civacir received Orphan Drug Designation from the FDA in November 2002.

Nicotine Addiction Program:

NicVAX™ (Nicotine Conjugate Vaccine)

Tobacco use is the single leading preventable cause of death in the U.S. According to the CDC, in 2000, an estimated 46.5 million adults were current smokers. Further, in the U.S., per the American Lung Association, there are currently an estimated 4.5 million adolescent smokers between the ages of 12 - 17. The CDC estimates that over 750,000 new youth smokers are being added each year. As reported by the CDC, tobacco use causes more than 400,000 deaths per year, more than AIDS, alcohol, drug abuse, car crashes, murders, suicides, and fires combined. Economically, smoking is reported to

be responsible each year for greater than $75 billion in medical expenditures and $82 billion in indirect costs (lost work time and disability). On a worldwide basis, the statistics are even more significant as at least 1.1 billion people, or one-third of the global adult population, use tobacco, as reported by the World Bank Group in 1999.

Nicotine is a very small molecule, too small to be detected by the immune system (sub-antigenic). Once the molecule enters the bloodstream following nicotine intake, it quickly passes the blood/brain barrier. Once nicotine enters the brain, it binds to and activates neuroreceptors in the brain believed to be the source of positive reinforcement from nicotine. The repeated use of tobacco leads to nicotine addiction. Addiction to nicotine is the primary reason people find it difficult to stop using tobacco in its various forms. NicVAX is an experimental vaccine to prevent and treat nicotine addiction. NicVAX has been developed to cause the immune system to produce high levels of nicotine-specific antibodies following vaccination. Our researchers have shown that it is possible to link a hapten (a very small molecule like nicotine) to a carrier protein. The carrier protein, which is the same that is used in the manufacture of StaphVAX, is a non-toxic, carrier protein derived from the bacteria Pseudomonas aeruginosa. Once given the vaccine, the subjects’ immune systems produce proteins called antibodies which are specific to nicotine and which nicotine binds to on subsequent exposure to the molecule. Vaccination with NicVAX has been shown to generate high levels of nicotine-specific antibodies in animals. Results with NicVAX in animal models indicate that nicotine bound to the antibodies is unable to cross the blood/brain barrier. One of the potential effects of a nicotine vaccine might be to prevent positive feedback from nicotine should users be exposed to nicotine during an attempt to break their habit. The antibodies resulting from use of the vaccine have been shown to ease nicotine dependence in rats, reduce nicotine levels in the brains of rats by 64% compared to control rats, prevent nicotine-induced blood pressure increases, and reduce the hyperactivity induced in rats in response to nicotine injections.

NicVAX uses a similar conjugate vaccine technology as was developed for StaphVAX and other anti-bacterial vaccines in our pipeline. The result is a vaccine with a significantly greater immunogenicity than experimental vaccines derived by more classical conjugation technologies. We believe that antibodies to NicVAX are highly specific to nicotine and are of higher affinity than has been achievable with other conjugation technologies. In May 2001, the U.S. Patent and Trademark Office (“USPTO”) issued a U.S. Patent to us for NicVAX entitled “Hapten-Carrier Conjugates for Treating and Preventing Nicotine Addiction.” This patent covers the binding of nicotine to a protein carrier for use as a vaccine for treating and preventing nicotine addiction. In February 2003, a second U.S. patent covering NicVAX for treatment and prevention of nicotine addiction was granted to us. This patent covers the composition of NicVAX and the use of the vaccine to obtain antibodies and use of antibodies to prevent and treat nicotine addiction. Patent applications on NicVAX technology, on the resultant nicotine vaccine and its use to prevent and treat nicotine addiction have been filed outside the U.S.

In 2000, we and our collaborators at the University of Minnesota, Hennepin County Medical Center and the University of Houston — Clear Lake received a grant from the NIH’s NIDA in the amount of approximately $4 million over four years for the further research and development of NicVAX. Funding for the third year under this grant was approved for 2002 and we anticipate that funding will be approved for the fourth year of the grant. In November 2001, we announced the successful completion of preclinical toxicology studies for NicVAX, which were also funded by NIDA.

In May 2002, we commenced a placebo controlled, double-blinded Phase I clinical trial of NicVAX in normal, healthy, non-smoker volunteers with the assistance of funding from NIDA. The intent of the trial was to evaluate the safety and immunogenicity of the vaccine. Preliminary results of the trial were reported in October 2002. Analysis of blood samples from the participants showed that a single dose of vaccine resulted in a rapid immune response and generated nicotine specific antibodies. Local reactions to vaccination were generally mild to moderate, temporary and required no therapeutic intervention. Antibody levels were detected within 7-14 days of vaccination and were either maintained or continued to increase through at least 60 days post-vaccination. Based on these findings, we plan to initiate additional NIDA funded clinical trials of NicVAX in smokers and ex-smokers in the U.S. in 2003.

In February 2003, we initiated a placebo controlled, double-blinded Phase I/II study of NicVAX in smokers, ex-smokers and non-smokers. The trial, which is being conducted in collaboration with researchers at the University of Maastricht in the Netherlands, represents our first clinical trial conducted outside the U.S. The primary intent of this trial is to evaluate the development of specific nicotine antibody levels and safety of the vaccine in study participants. A total of 30 subjects will be enrolled in this trial, 21 smokers and 9 ex-smokers or non-smokers. They will receive at least three immunizations of NicVAX or placebo.

Other Programs:

RENs and RENt (Ring Expanded Nucleosides and Nucleotides)

Nucleosides and nucleotides are the building blocks of DNA and RNA. Our scientists and scientists at the University of Maryland Baltimore County (“UMBC”) have developed a novel, proprietary, platform technology, which permits the synthesis of a new class of nucleoside and nucleotide analogs called Ring Expanded Nucleosides (“RENs”) and Ring Expanded Nucleotides (“RENt”). Nucleoside and nucleotide analogs prepared using RENs technology have been shown to possess anti-microbial, anti-viral and anti-tumor activities in vitro. In addition to evaluating RENs compounds as stand-alone drugs, we believe there are opportunities to evaluate use of our current antibody-based biopharmaceutical products targeted at viruses in combination with RENs compounds.

In 1998, Nabi Biopharmaceuticals and UMBC were issued a U.S. patent with claims encompassing certain RENs and RENt compounds. We have an exclusive license from UMBC for the patented technology, inclusive of a pending patent application claiming therapeutic (anti-viral/anti-tumor) uses of these analogs. We have prepared a number of active compounds through our collaboration with UMBC under a series of Maryland Industrial Partnership grants. A lead compound, Nabi 3700.001, has been selected for further development. In pre-clinical in-vitro studies, this drug has been shown to have an acceptable toxicity profile and to have good anti-viral activity and specificity against HBV. Under the license agreement, we are obligated to pay UMBC a royalty based on net sales of products utilizing the licensed technology.

Staphylococcus aureus Vaccine for Mastitis

S. aureus is the most frequent cause of mastitis, one of the most common diseases afflicting dairy and beef cattle. This disease results in significantly higher costs for producers of dairy and beef products due to discarded milk, decreased productivity, treatment expense, and the inability of infected cows to suckle calves.

In October 2001, the USPTO issued a patent entitled “Staphylococcus aureus antigen-containing whole cell vaccine.” This patent covers the composition of a S. aureus vaccine, the method of vaccine preparation, and its use as a therapeutic or prophylactic agent to protect animals against infection. In July 2000 we reported on the results of a study in dairy cattle with a prototype of this vaccine as a therapeutic agent. The study, which was the result of research and development collaboration between our researchers and researchers at the U.S. Department of Agriculture and Michigan State University, reported that a trivalent whole-cell vaccine produced by us resulted in a cure rate of 54% as compared to antibiotic alone (4% cure rate). We consider our whole cell vaccine technology to be an out-licensing candidate.

STRATEGIC ALLIANCES

We are actively pursuing strategic alliances to assist in the development of some of the products in our pipeline and to expand our biopharmaceutical business. Our current key strategic alliances are discussed below.

Cangene Corporation

Under a license and distribution agreement with Cangene, we have exclusive rights to distribute and market WinRho SDF in the U.S. Cangene, which holds the FDA licenses for the product, is required to supply the necessary quantities of WinRho SDF to support such sales and shares equally in the profits from sales after accounting for the costs of production and selling expenses. The license and distribution agreement concludes in March 2005.

Chiron Corporation

We have an agreement with Chiron Corporation that grants us an exclusive supply agreement for four vaccines, including hepatitis C. In addition, we have rights to 10 additional Chiron vaccines for use in humans to produce immunotherapeutic products. The agreement may also grant us access to Chiron’s adjuvant, MF 59. We will be responsible for all development, manufacturing and worldwide distribution of these products. We may terminate the agreement on a product-by-product basis in which event we shall transfer to Chiron all of our rights with respect to the product as to which the agreement has been terminated. Similarly, Chiron may terminate its obligations to supply immunizing agents to us on a product-by-product basis, in which event Chiron shall grant to us a license of the technology necessary for us to manufacture the applicable immunizing agent and the financial arrangements in the Chiron Agreement with respect to such agent shall continue.

DSM Pharmaceuticals, Inc.

In 1999, we entered into a five-year agreement with DSM for exclusive distribution rights in the U.S. and Canada for Aloprim. Under this agreement, we sell and DSM manufactures the product and both companies share equally in profits from the sale of the product after accounting for the costs of production and selling expenses for the first $4 million of product sales in any given year. On sales of Aloprim in excess of $4 million in a year, profits are shared 70% to us and 30% to DSM. In the event DSM obtains sales and distribution rights in additional territories to the U.S. and Canada, we can purchase the rights to Aloprim in these additional territories. The current distribution agreement concludes in June 2004. We have the option to purchase the rights to manufacture and distribute Aloprim from DSM prior to expiration of the agreement.

Baxter Healthcare Corporation

In 1997, we acquired exclusive rights to Autoplex T in the U.S., Canada and Mexico from Baxter. In connection with the acquisition, Baxter agreed to manufacture Autoplex T until May 2000 or such later time as may be determined under the terms of a consent order entered into between Baxter and the Federal Trade Commission (“FTC”), but in any event four months after we receive approval from the FDA to manufacture Autoplex T. At the discretion of the FTC, the period Baxter manufactures Autoplex T can be extended for up to four twelve-month intervals. The FTC approved the third twelve-month extension beginning in May 2002. The FTC could require us to return our rights to Autoplex T to Baxter if we do not obtain FDA approval to manufacture the product by May 2003 or by a later date agreed to by the FTC. We anticipate that the period Baxter manufactures Autoplex T under the terms of the consent order from the FTC will be extended for the twelve-month period through May 2004. If the rights revert to Baxter and Baxter later sells these rights, we will share equally with Baxter in the proceeds of any such sale, and under certain circumstances Baxter will be required to make a specified payment to us. Upon FDA licensure to manufacture the product, we are obligated to pay $1.0 million to Baxter, subject to recovery of fifty percent (50%) of expenditures incurred to license the product in excess of $6.0 million.

Dow Biopharmaceutical Contract Manufacturing Services

In May 2000, we completed agreements with Dow for the contract production and commercial supply of StaphVAX. The manufacturing process for StaphVAX is being transferred to Dow from our pilot manufacturing plant in Rockville, Maryland. We plan to use StaphVAX clinical material from initial clinical lots manufactured at Dow under current Good Manufacturing Practices (“cGMP”) for an immunogenicity study and for the confirmatory Phase III trial planned to commence in 2003. We expect Dow to complete scale-up of manufacturing at the facility and to begin the production of consistency lots of StaphVAX in 2004. The contract manufacturing agreements required us to make certain payments to Dow to secure future access to commercial vaccine manufacturing capacity and to enable Dow to ready its facility for the future commercial scale manufacture of StaphVAX, its intended use. These payments have been recorded as a Manufacturing Right and included in Intangible Assets. Amortization of the Manufacturing Right is expected to commence when commercial manufacture of StaphVAX commences at Dow. The contract to ready the Dow facility to manufacture StaphVAX, which was originally scheduled to expire in October 2002, has been extended to March 2003. We expect to execute amended contracts with Dow to complete readying the facility for its intended use, the commercial manufacture of StaphVAX in March 2003. These contracts are expected to require us to make significant additional payments to Dow to ready its facility for the commercial manufacture of StaphVAX which will also be recorded as a Manufacturing Right.

Public Health Services/National Institutes of Health

Under a license agreement with the PHS/NIH, we have exclusive rights to a U.S. patent relating to a carbohydrate/protein conjugate vaccine against Staphylococcus and are obligated to pay PHS a royalty based on net sales of products using this technology. The licensed patent rights cover staphylococcal vaccines including StaphVAX. The license terminates on the date that the patent rights expire. These patent rights expire in the U.S. in April 2010.

CUSTOMER RELATIONSHIPS

We sell our biopharmaceutical products to wholesalers, distributors, hospitals and home healthcare companies and sell our antibody products to pharmaceutical and diagnostic product manufacturers.

In connection with the sale of the majority of our antibody collection business and testing laboratory, we entered into an agreement for the purpose of assuring that each party would have the ability to meet supply commitments to third parties after completion of the sale. Under this agreement we are obligated to provide RhoD antibodies at our cost plus a handling fee. This agreement terminates in December 2004. Non-specific antibody sales include shipments to a single customer under a supply contract, which was retained by us following the sale of the majority of the antibody collection business and testing laboratory in September 2001. The purchaser of the majority of the antibody collection business and testing laboratory continues to supply us with non-specific antibodies to fulfill this obligation at the selling price under this contract. Because we retain the risk of credit loss with this customer, we record revenues but no margin on these sales. Such sales totaled $55.6 million in 2002. This agreement ends in May 2003.

For our other antibody product contracts, pricing for product deliveries is generally determined by mutual agreement prior to the beginning of the contract and fixed for the contract term, generally one year or less. The contracts generally provide for price increases/decreases to reflect changes in customer specifications and new governmental regulations. In addition, in 2003 we expect to sell antibody products in individually negotiated transactions that will be subject to market conditions at the time of negotiation. Our profit margins for these transactions may be adversely or beneficially affected by market conditions for antibody products at those times.

Table of Contents

Sales for the year ended December 28, 2002 included one customer of our antibody products segment, Bayer Corporation, and two customers of our biopharmaceutical products segment, Cardinal Health, Inc. and AmerisourceBergen, representing 35%, 15% and 14% of total consolidated sales, respectively.

SUPPLY AND MANUFACTURING

Biopharmaceutical Products

We manufacture Nabi-HB in our biopharmaceutical manufacturing facility in Boca Raton, Florida. Additionally, we have manufactured clinical lots of our investigational products, Altastaph and Civacir, in this facility. In December 2001, we signed a 10-year agreement with Inhibitex, Inc. to manufacture its investigational antibody-based biopharmaceutical product in our Boca Raton, Florida biopharmaceutical manufacturing facility and have produced clinical lots under this agreement in 2002.

In April 2001, we signed an agreement with Acambis to provide specialty antibodies at our antibody collection centers under an IND to be submitted by Acambis to the FDA and to manufacture their antibody-based therapeutic product. In 2002, Acambis advised us that the IND study was withdrawn.

We are required to purchase our requirements of WinRho SDF from Cangene, which has granted us exclusive distribution and marketing rights to the product in the U.S., under an agreement that terminates in March 2005. We collected and supplied a portion of the RhoD antibodies required for the manufacture of WinRho SDF to Cangene in 2002.

Baxter currently manufacturers Autoplex T for us under the terms of a consent order entered into between Baxter and the FTC. At the discretion of the FTC, the period Baxter manufactures Autoplex T can be extended for up to four twelve-month intervals. The FTC approved the third twelve-month extension beginning in May 2002. We anticipate that the period Baxter manufactures Autoplex T under the terms of the consent order from the FTC will be extended for the twelve-month period through May 2004.

DSM manufactures Aloprim for us and has granted us exclusive distribution rights in the U.S. and Canada under an agreement that terminates in June 2004. DSM is obligated to supply Aloprim to us through the expiration date of the distribution agreement. During 2002, we experienced delivery shortfalls of Aloprim from DSM. If delivery shortfalls occur in 2003, product sales of Aloprim will be negatively impacted. We have the option to purchase the rights to manufacture and distribute Aloprim from DSM prior to expiration of the agreement.

We manufacture diagnostic products at our Miami, Florida facility and have manufactured both pre-clinical and clinical lots of vaccine products at our pilot facility in Rockville, Maryland. We are in the process of constructing a laboratory and cold storage facility in Boca Raton, Florida at which we expect to manufacture our diagnostic products in the future. This facility is expected to replace our leased facility in Miami, Florida in 2003.

Antibody Collection Process

We currently collect and process antibodies from our nine collection centers located across the U.S. Each center is licensed and regulated by the FDA. Most of our centers are located in urban areas and some are near universities and military bases. Prospective donors are required to complete a medical questionnaire and are subject to laboratory testing and a physical examination under the direction or supervision of a physician. Following this screening, antibodies are collected from suitable donors by means of a process known as plasmapheresis.

PATENTS AND PROPRIETARY RIGHTS

Our continued success in our biopharmaceutical business will depend, in part, on our ability to obtain and protect our patent rights, trade secrets and other intellectual property. We have acquired title or obtained licenses to a number of patents or patent applications and have filed a number of patent applications of our own. See also “Risk Factors — Uncertainty of Legal Protection Afforded by Patents and Proprietary Rights.”

GOVERNMENT AND INDUSTRY REGULATION

The collection, processing and sale of our products as well as our research, pre-clinical development and clinical trials are subject to regulation for safety and efficacy by numerous governmental authorities in the U.S. and other countries, including the United Kingdom, Germany and France. Domestically, the federal Food, Drug and Cosmetic Act, the Public Health Service Act, and other federal and state statutes and regulations govern the collection, testing, manufacturing, safety, efficacy, labeling, storage, record keeping, transportation, approval, advertising and promotion of our products. We believe we are in substantial compliance with all relevant laws and regulations.

Biopharmaceutical Products

Vaccines and human polyclonal antibody products are classified as biological products under FDA regulations. The steps required before a biological product may be marketed in the U.S. generally include pre-clinical studies and the filing of an IND application with the FDA, which must be accepted by the FDA before human clinical studies may commence. The initial human clinical evaluation, called a Phase I trial, generally involves administration of a product to a small number of normal, healthy volunteers to test for safety. Phase II trials involve administration of a product to a limited number of patients with a particular disease to determine dosage and safety, as well as provide indications of efficacy. Phase III trials examine the efficacy and safety of a product in an expanded patient population at geographically dispersed clinical sites. Phase IV trials monitor for adverse effects and are undertaken post-licensure, such as additional large-scale, long-term studies of morbidity and mortality. The FDA reviews the clinical plans and the results of trials and can discontinue the trials at any time if there are significant safety issues. Biological products, once approved, currently have no provision allowing competitors to market generic versions. Each biological product must undergo the entire development process in order to be approved.

The results of all trials are submitted in the form of a BLA/New Drug Application (“NDA”) for approval to commence commercial sales. For BLA/NDA approval, the FDA requires, among other things, that the prospective manufacturer’s methods conform to the agency’s cGMP regulations, which must be followed at all times and that the prospective manufacturer submit three conformance lots in support of the application. In complying with standards set forth in these regulations, manufacturers must continue to expend time, money and effort in the area of production and quality control to ensure full regulatory compliance. The approval process is affected by several factors, including the severity of the disease, the availability of alternative treatments, and the risks and benefits demonstrated in clinical trials. The FDA also may require post-marketing surveillance to monitor potential adverse effects of the product. Congress or the FDA in specific situations can modify the regulatory process.

Antibody Products

The collection, storage and testing of antibodies and antibody-based products derived from human plasma are strictly regulated by the FDA. In order to operate in the U.S., an antibody collection facility must hold a Biologics License issued by the FDA’s Center for Biologics Evaluation and Research. Each collection facility must be regularly inspected and approved in order to maintain licensure. In addition, collection centers require FDA product licenses to collect each specialty antibody product.

Table of Contents

We hold Biologics License No. 1022 covering all of our centers and the manufacturing plant for antibody-based biopharmaceutical products. We are also subject to and are required to be in compliance with pertinent regulatory requirements of the foreign countries to which we export products.

We continually pursue our commitment to quality and compliance with applicable FDA regulations and other regulatory requirements through our own internal training and quality assurance programs. As part of our commitment to quality, we operate under the International Quality Plasma Program (“iQPP”) that was initiated by the Plasma Protein Therapeutics Association (formerly known as American Blood Resources Association), an organization that establishes and recommends guidelines for the antibody industry. iQPP imposes standards on antibody collection facilities in addition to those presently required by the FDA. iQPP certification has proven to be increasingly significant and fractionators worldwide now require that the supply of antibodies come only from iQPP certified centers. All collection facilities owned by us are iQPP certified.

Orphan Drug Act

Aloprim has received Orphan Drug Designation for treatment of chemotherapy-induced hyperuricemia through May 2003. Nabi-HB Intravenous has received Orphan Drug Designation under this Act for prevention of hepatitis B re-infection in liver transplant recipients and for which we filed a BLA in November 2002. In November 2002, the FDA also granted our investigational product, Civacir, Orphan Drug Designation for prevention of hepatitis C infection in liver transplant recipients. Under the Orphan Drug Act, the FDA may designate a product as having Orphan Drug status to treat a “rare disease or condition,” which currently is defined as a disease or condition that affects populations of less than 200,000 individuals in the U.S. at the time of designation, or, if victims of a disease number more than 200,000, for which the sponsor establishes that costs of development will not be recovered from U.S. sales in seven years. When a product is designated an Orphan Drug, the sponsor is entitled to receive certain incentives to undertake the development and marketing of the product. In addition, the sponsor that obtains the first marketing approval for a designated Orphan Drug for a given indication effectively has marketing exclusivity for a period of seven years. There may be multiple designations of Orphan Drug status for a given drug and for different indications. However, only the sponsor of the first BLA approved for a given drug for its use in treating a given rare disease may receive marketing exclusivity.

COMPETITION

Biopharmaceutical Products

We believe that Nabi-HB has achieved a significant share of the domestic market and that our access to the vaccines and specialty antibodies necessary for the manufacture of Nabi-HB will allow us to retain a significant market share. Anti-HBs antibodies produced at our antibody collection centers are currently used in the manufacture of Nabi-HB. There is one antibody-based therapy for prevention of hepatitis B post exposure currently on the market that competes with Nabi-HB. See also “Supply and Manufacturing — Biopharmaceutical Products.” In November 2002, we submitted a BLA to the FDA for the use of an IV formulation of Nabi-HB to prevent liver transplant patients from suffering re-infection with HBV. Nabi-NB Intravenous has received Orphan Drug Designation from the FDA. In January 2003, we received notification that the FDA accepted our IV BLA for priority review. A priority review means that the FDA commits to responding to this BLA within six months, instead of the statutorily required ten months.

WinRho SDF is the first and only RhoD antibody-based biopharmaceutical product approved for the treatment of ITP. We believe that WinRho SDF has a significant and growing share of the domestic market for ITP treatment. Competing therapies include steroids, IVIG, and splenectomy (a surgical procedure to remove the spleen).

Autoplex T competes in the anti-inhibitor segment of the hemophilia A market. Autoplex T and other competitive agents are used to treat patients that have developed inhibitors (antibodies) to Factor VIII,

the standard therapy for people suffering from hemophilia A. There are two significant biopharmaceutical products currently on the market that compete with Autoplex T.

Aloprim is the first and only IV allopurinol therapy available for the treatment of chemotherapy-induced hyperuricemia. Aloprim provides a therapeutic option for patients that cannot tolerate oral allopurinol therapy. Aloprim has received Orphan Drug Designation for treatment of chemotherapy-induced hyperuricemia through May 2003. In 2002, a new competitive agent using a different mechanism of action was introduced into this market.

Antibody Products

We, and other independent suppliers of antibodies, sell these raw materials principally to pharmaceutical companies that process this raw material into finished products. Although these pharmaceutical companies generally own plasmapheresis centers, in the aggregate they purchase a portion of their antibody requirements from independent suppliers. There is competition among these independent suppliers as well as fractionators who own their own plasmapheresis centers. We compete for sales by maintaining competitive pricing and by providing customers with high-quality products and superior customer service. Management believes we have the ability to continue to compete successfully in these areas. As we are able to achieve licensure for products in our research and development pipeline, we anticipate a strategic shift in our antibodies segment of converting non-specific antibodies production into the production of specialty antibodies which we will use to manufacture our own antibody-based biopharmaceutical products.

We compete for donors with pharmaceutical companies that obtain antibodies for their own use through their own collection centers, other commercial collectors of antibodies, and non-profit organizations such as the American Red Cross and community blood banks that solicit donations of whole blood. We compete for donors by providing competitive incentives and outstanding donor service, by implementing programs to attract donors through education as to the uses for collected antibodies, by encouraging groups to have their members become donors for fund raising purposes and by improving the attractiveness of our collection facilities.

EMPLOYEES

We employed 722 persons at December 28, 2002. We believe that the relations between our management and our employees are generally good.

FINANCIAL INFORMATION ABOUT SEGMENTS AND GEOGRAPHIC AREAS

This Annual Report on Form 10-K contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. Statements in this Annual Report on Form 10-K that are not historical facts are hereby identified as “forward-looking statements” for the purpose of the safe harbor provided by Section 21E of the Securities Exchange Act of 1934 and Section 27A of the Securities Act of 1933. Words such as “estimate,” “project,” “plan,” “intend,” “expect,” “believe” and similar expressions are intended to identify forward-looking statements. All forward-looking statements are necessarily only estimates of future results and there can be no assurance that actual results will not differ materially from expectations, and, therefore, investors are cautioned not to place undue reliance on such statements. Set forth below is a discussion of certain factors, which could cause our actual results to differ materially from the results projected or suggested in such forward-looking statements. Investors should understand that it is not possible to predict or identify all such factors and that this list should not be considered a complete statement of all potential risks and uncertainties. We undertake no obligation to update any forward-looking statements as a result of future events or developments.

Our Rights to Three Existing Biopharmaceutical Products May Expire

Our rights to WinRho SDF and Aloprim expire in 2005 and 2004, respectively. There can be no assurance that our rights to these products will be extended on the same terms as they now exist or at all. DSM has advised us that it does not intend to extend the Aloprim agreement. We have the option to purchase the rights to Aloprim in the territories now covered by the Aloprim agreement.

Pursuant to the terms under which we acquired our rights to Autoplex T from Baxter, the FTC could require us to return to Baxter our rights to Autoplex T if we do not obtain FDA approval to manufacture the product by May 2003 or a later date agreed to by the FTC. We will not obtain FDA approval to manufacture Autoplex T by May 2003 and will seek an extension of our rights to market Autoplex T from the FTC to May 2004. Although we believe we will receive the extension, there can be no assurance that it will be granted by the FTC. The terms under which we acquired our rights to Autoplex T provided for up to four one-year extensions. Such an extension would represent the fourth such one-year extension granted to us by the FTC.

We Are and Will Continue to be Dependent Upon Third Parties to Manufacture Our Products

We do not currently manufacture three of our four marketed biopharmaceutical products and are dependent upon third parties to manufacture these products for us. The failure by these manufacturers to timely meet our needs for these products could have a material adverse effect on our future business, financial condition and results of operations. This has occurred in the past. Biopharmaceutical product sales were constrained in 2000 because of the inability of the contract manufacturer for WinRho SDF and Nabi-HB to supply product for a period of time. In 2000, 2001 and 2002, our ability to market Autoplex T was adversely affected by the inability of the manufacturer of this product to reliably supply us with necessary quantities of this product at desired potency levels. The manufacturer of Aloprim is currently transferring the manufacture of this product to an alternate site within their manufacturing facility. This transfer is expected to be complete in 2003. If the transfer of the manufacture of Aloprim to the alternate facility site is not successful, future sales of this product will be adversely affected.

Our research and development pipeline principally involves specialty vaccines. We have no current plans to construct a FDA-licensed facility to manufacture these vaccines. For the commercial manufacture of StaphVAX, we have entered into long-term contracts for production and commercial supply with Dow. We will be dependent on Dow and other third parties for the manufacture of StaphVAX and other products in our research and development pipeline. Such dependence is subject to the same risks that apply to the manufacture of our currently marketed biopharmaceutical products.

Table of Contents

We Have Limited Manufacturing Capability and Experience; Adverse Impact of Under-Utilization

We began commercial manufacturing of Nabi-HB in the fourth quarter of 2001. We have not previously owned or operated a manufacturing facility and have limited experience in commercial, large-scale manufacturing of biopharmaceutical products. For the foreseeable future, we will not utilize the full manufacturing capacity of the facility and there can be no assurance that the facility can be operated efficiently. Further, there can be no assurance we will have products to manufacture either on our own behalf or on behalf of third parties, to offset the cost of the facility’s operation. Our failure to successfully operate our new manufacturing facility would have a material adverse effect on our future business, financial condition and results of operations.

Manufacturing products at a single site may present risks if a disaster (such as a fire or hurricane) causes interruption of manufacturing capability. In such an event, we will have to resort to alternative sources of manufacturing that could increase our costs as well as result in significant delays while required regulatory approvals are obtained. Any such delays or increased costs could have a material adverse effect on our future business, financial conditions and results of operations.

Risks Associated with Sales of Our Products to a Small Number of Customers

We sell a significant portion of our products to pharmaceutical wholesalers and distributors and major pharmaceutical companies. A loss of any major customer or a material reduction in such customer’s purchases from us could have a material adverse effect on our results of operations or financial condition. We also maintain individually significant receivable balances with these customers. If these customers become unable or unwilling to pay amounts owed to us, our financial condition or results of operations could be adversely affected.

Risks Associated with Antibody Products Supply and Demand; Potential Adverse Impact on Nabi-HB

Our antibody collection centers and our customers for antibody products are subject to extensive regulation by the FDA and non-U.S. regulatory authorities. Concern over the safety of antibody products has resulted in the adoption of more rigorous screening procedures by regulatory authorities and manufacturers of antibody products. In prior years, these changes have resulted in significantly increased costs to us in providing non-specific and specialty antibodies to our customers. New procedures, which include a more extensive investigation into a donor’s background, as well as more sensitive tests, have also disqualified numerous potential donors and discouraged other donors who may be reluctant to undergo the screening procedures. These more stringent measures could adversely affect our antibody production with a corresponding adverse effect on our future business, financial condition and results of operations. In addition, our efforts to increase production to meet customer demand may result in higher costs to attract and retain donors.

Most of the antibodies we collect, process and sell to our customers are used in the manufacture of biopharmaceutical products to treat certain diseases. Several companies are marketing and developing products to treat some of these diseases based upon technology that would lessen or eliminate the need for human antibodies. Such products could adversely affect the demand for antibodies and antibody-based biopharmaceutical products. Although products utilizing technology developed to date have not proven as cost-effective and marketable to healthcare providers as products based on human antibodies, we are unable to predict the impact on our business of future technological advances on our business.

The worldwide supply of antibodies has fluctuated historically. Future changes in government regulation relating to the collection, fractionation and use of antibodies or any negative public perception about the antibody collection process or the safety of products derived from blood or antibodies could further adversely affect the overall supply of or demand for antibodies. Increases in supply or decreases in demand of antibody products could have a material adverse effect on our future business, financial condition and results of operations.

Our ability to manufacture Nabi-HB is dependent upon the availability of anti-HBs specialty antibodies that we primarily obtain from our FDA approved antibody collection centers. Reduced availability of antibodies could adversely affect our ability to manufacture an adequate amount of Nabi-HB, with the result that our future business, financial condition and results of operations will suffer.

Costs of Research and Development

We have incurred and expect to continue incurring significant expenses associated with our biopharmaceutical research and development activities, including the cost of clinical trials relating to

24


Table of Contents

product development and marketing expenses relating to product introduction. Products under development may not generate sales for several years or at all. We currently do not have the financial resources to concurrently fund all of our biopharmaceutical product development programs to completion. Our ability to continue to fund all of our concurrent ongoing research and development activities is currently dependent on our ability to generate sales from our biopharmaceutical and antibody products or obtain financing. There can be no assurance, therefore, that we will be able to continue to fund our research and development activities at the level required to commercialize all of our biopharmaceutical product development programs, and if we are required to reduce the funding for certain of our research and development activities, this could have a material adverse effect on our future prospects.

Strategic Alliances

We are pursuing strategic alliances with third parties for the development and/or commercialization of certain of our biopharmaceutical products. No assurance can be given that we will be successful in these efforts or, if successful, that the collaborators will conduct their activities in a timely manner. If we are not successful in our efforts, our ability to continue to develop our products may be adversely affected. Even if we are successful, if any of our collaborative partners violate or terminate their agreements with us or otherwise fail to conduct their collaborative activities in a timely manner, the development or commercialization of products could be delayed, and we might be required to devote significant additional resources to product development and commercialization or terminate certain development programs. In addition, there can be no assurance that disputes will not arise in the future with respect to the ownership of rights to any technology developed with third parties. These and other possible disagreements between collaborators and us could lead to delays in the collaborative research, development or commercialization of certain products or could require or result in litigation or arbitration, which would be time-consuming and expensive and could have a material adverse effect on our future business, financial condition and results of operations.

Uncertainty of New Product Development

Our future success will depend on our ability to achieve scientific and technological advances and to translate such advances into commercially competitive products on a timely basis. Our biopharmaceutical products under development are at various stages, and substantial further development, pre-clinical testing and clinical trials will be required to determine their technical feasibility and commercial viability. The proposed development schedules for these products may be affected by a variety of factors, including technological difficulties, competition, failure to achieve desired results in clinical trials, proprietary technology positions of others, reliance on third parties for manufacturing, failure to market effectively, changes in government regulation and funding. Positive results for a product in a clinical trial do not necessarily assure that positive results will be obtained in future clinical trials or that government approval to commercialize the product will be obtained. In addition, any delay in the development, introduction or marketing of our products under development could result either in such products being marketed at a time when their cost and performance characteristics would not be competitive in the marketplace or in a shortening of their commercial lives. There can be no assurance that our biopharmaceutical products under development will prove to be technologically feasible, commercially viable and able to obtain necessary regulatory approvals and licenses on a timely basis, if at all. Our failure to successfully develop and commercialize in a timely manner our biopharmaceutical products and obtain necessary regulatory approvals could have a material adverse effect on our future operations. In particular, our failure to obtain FDA approval for StaphVAX on a timely basis could adversely affect our market valuation.

Competitive Market for Biopharmaceutical Products

Our currently marketed biopharmaceutical products compete with those of other companies. Most of these companies have greater financial resources, research and development capabilities and marketing organizations than we do. We may need to supplement our own sales efforts with the resources of a partner. If we so elect, there can be no assurance that we will be able to find a partner on acceptable

25


Table of Contents

terms or at all, or that any such partner will be successful in its efforts. Aloprim currently enjoys Orphan Drug status, which expires in May 2003. Once Orphan Drug status ends, other products that compete with Aloprim may be introduced. If we succeed in bringing one or more products to market, we will compete with many other companies that may have extensive and well-funded marketing and sales operations. Our failure to successfully market new biopharmaceutical products and compete with new entrants to markets served by our existing products could have a material adverse effect on our future business, financial condition and results of operations.

Uncertainty of Market Acceptance

There can be no assurance that any of our products in development will achieve market acceptance. The degree of market acceptance will depend upon a number of factors, including the receipt of regulatory approvals, the establishment and demonstration in the medical community of the clinical efficacy and safety of our products and their potential advantages over existing treatment methods, the prices of such products, and reimbursement policies of government and third party payers. The failure of our product pipeline to gain market acceptance could have a material adverse effect on our future business, financial condition and results of operations.

Dependence of the Antibody Business on a Small Number of Customers; Effect of Existing Contracts

Our antibody sales are currently concentrated among a few large pharmaceutical companies. During the 2002, 2001 and 2000 fiscal years, antibody sales to our top two customers collectively accounted for approximately 74%, 66%, and 60%, respectively, of our antibody sales. Our contract to sell antibodies to one of these customers was assigned in September 2001 in connection with the sale of the majority of our antibody collection centers. The loss of certain remaining major customers or a material reduction in these major customers’ purchases of antibodies could have a material adverse effect upon our future business, financial condition and results of operations. If these customers are unable to comply with FDA regulations and non-U.S. regulations, their manufacturing facilities may be temporarily closed which will reduce the need for antibodies provided by us. Plant closures and reductions in customers’ production because of FDA regulatory problems have occurred in recent years, and our financial performance has been adversely affected as a result. There can be no assurance that the customer regulatory problems, which are not within our control, will not reoccur with an adverse impact on us in the future.

A significant amount of our antibodies are sold under contracts that extend for a period up to one year. Certain of these contracts do not permit us to increase prices during the year except to reflect changes in customer specifications and new governmental regulations. If our costs of collecting antibodies under these certain contracts rise for reasons other than changes in customer specifications and new governmental regulations, we are unable to pass on these cost increases to our antibody product customers except with the consent of the customer. Moreover, our existing contracts do not generally permit us to expeditiously take advantage of market changes that could benefit us.

Government Regulation; Uncertainty of Regulatory Approvals

Research, pre-clinical development, clinical trials, manufacturing and marketing of our products are subject to extensive regulation by various government authorities in the U.S. The process of obtaining FDA and other required regulatory approvals is lengthy and expensive, and the time required for such approvals is uncertain. The approval process is affected by such factors as the severity of the disease, the availability of alternative treatments, and the risks and benefits demonstrated in clinical trials. The FDA also may require post-marketing surveillance to monitor potential adverse effects of the product. Congress or the FDA in specific situations can modify the regulatory process. Many of our clinical trials are at a relatively early stage and, except for Nabi-HB, WinRho SDF, Autoplex T, Aloprim and certain non-specific and specialty antibody products, no approval from the FDA or any other government agency for the manufacturing or marketing of any other products under development has been granted. There can be no assurance that we will be able to obtain the necessary approvals for manufacturing or marketing of any of our products. Failure to obtain additional FDA approvals of products currently

26


Table of Contents

marketed or FDA approval for products under development could have a material adverse effect on our future business, financial condition and results of operations. Once approved, a product’s failure to comply with applicable regulatory requirements could, among other things, result in warning letters, fines, suspension or revocation of regulatory approvals, product recalls or seizures, operating restrictions, injunctions and criminal prosecutions.

Although we do not have material sales of our biopharmaceutical products outside the U.S., our goal is to expand our non-U.S. presence for these products. Distribution of our products outside the U.S. is subject to extensive government regulation. These regulations, including the requirements for approvals or clearance to market, the time required for regulatory review and the sanctions imposed for violations, vary from country to country. There can be no assurance that we will obtain regulatory approvals in such countries or that we will not be required to incur significant costs in obtaining or maintaining our foreign regulatory approvals. In addition, the exports by us of certain of our products that have not yet been cleared for domestic commercial distribution may be subject to FDA export restrictions. Failure to obtain necessary regulatory approvals, the restriction, suspension or revocation of existing approvals or any other failure to comply with regulatory requirements would have a material adverse effect on our future business, financial condition and results of operations.

Our U.S. manufacturing, antibody collection, labeling, storage and distribution activities also are subject to strict regulation and licensing by the FDA. Our biopharmaceutical manufacturing facility in Boca Raton, Florida is subject to periodic inspection by the FDA, and from time to time, we may receive notices of deficiencies from the FDA as a result of such inspections. Our antibody collection centers in the U.S. are also subject to periodic inspection by the FDA, and from time to time we may receive notices of deficiencies from the FDA as a result of such inspections. Our failure or the failure of our biopharmaceutical manufacturing facility or our antibody collection centers to continue to meet regulatory standards or to remedy any such deficiencies could result in corrective action by the FDA, including closure of our biopharmaceutical manufacturing facility or one or more antibody collection centers and fines or penalties. New regulations may be enacted and existing regulations or their interpretation or enforcement are subject to change. Therefore, there can be no assurance that we will be able to continue to comply with any regulations or that the costs of such compliance will not have a material adverse effect on our future business, financial condition and results of operations.

Potential Adverse Effect of Litigation

Antibodies collected by us, antibody-based products manufactured by us, antibody-based products marketed by us and antibody-based products manufactured by our customers run the risk of being HIV-contaminated or contaminated with another virus. As a result, suits may be filed against our customers and us claiming that the plaintiffs became infected with HIV or other viruses as a result of using the contaminated products. Such suits have been filed in the past related to HIV-contaminated antibodies, and in a number of suits we were one of several defendants. With the exception of one suit that is still pending, all of these suits have been dismissed without liability to us. No assurance can be given that additional lawsuits relating to infection with HIV or other viruses will not be brought against us by persons who have become infected with HIV or other viruses from antibody fractionates.

Pharmaceutical companies are increasingly subject to litigation, including class action suits, and governmental and administrative investigations and proceedings related to product pricing and marketing practices. We have been named as one of over 40 pharmaceutical and biopharmaceutical defendants in three class action lawsuits. See “Legal Proceedings” at Item 3 in Part I. There can be no assurance that lawsuits based on other causes of action will not be filed or that we will be successful in the defense of any or all existing or potential future lawsuits. Defense of suits can be expensive and time-consuming, regardless of the outcome, and an adverse result in one or more suits could have a material adverse effect on our future business, financial condition and results of operations.

27


Table of Contents

Access to Insurance

Product liability and directors and officers insurance for the biopharmaceutical industry is generally expensive to the extent it is available at all. There can be no assurance that we will be able to maintain such insurance on acceptable terms or that we will be able to secure increased coverage if the commercialization of our products progresses, or that existing or future claims against us will be covered by our product liability insurance. Moreover, there can be no assurance that the existing coverage of our insurance policy and/or any rights of indemnification and contribution that we may have will offset existing or future claims. A successful claim against us with respect to uninsured liabilities or in excess of insurance coverage and not subject to any indemnification or contribution could have a material adverse effect on our future business, financial condition and results of operations.

Limited Property Insurance

We maintain significant real property assets in Florida. Property insurance for companies with a high concentration of property assets in Florida is generally expensive to the extent it is available at all. There can be no assurance that we will be able to maintain such insurance on acceptable terms or that we will be able to secure increased coverage if the value of our property increases.

Additional Financing Requirements and Access to Capital

We may need to raise additional capital to increase funding of our product research, development and marketing activities or to acquire additional products. We may seek additional funding through public or private equity or debt financing, collaborative arrangements with strategic partners or from other sources. There can be no assurance, however, that additional financing will be available on acceptable terms, if at all. If adequate funds are not available, we may have to defer certain investments in the areas of research, product development, manufacturing, marketing activity or business development, or otherwise modify our business strategy, and our future business and future prospects could be materially and adversely affected.

Uncertainty of Legal Protection Afforded by Patents and Proprietary Rights

The patent positions of biopharmaceutical firms generally are highly uncertain and involve complex legal and factual questions. There can be no assurance that existing patent applications will result in issued patents, that we will be able to obtain additional licenses to patents of others or that we will be able to develop additional patentable technology of our own. Because patent applications in the U.S. are not disclosed by the Patent and Trademark Office until patents issue, and because publication of discoveries in the scientific or patent literature often lags behind actual discoveries, we cannot be certain that we were the first creator of inventions covered by our pending patent applications or that we were the first to file patent applications for such inventions. There can be no assurances that any patents issued to us will provide us with competitive advantages or will not be challenged by others. Furthermore, there can be no assurance that others will not independently develop similar products, or, if patents are issued to us, design around such patents.

A number of biopharmaceutical companies, biotechnology companies, universities and research institutions have filed patent applications or received patents relating to products or processes competitive with or similar to ours. Some of these applications or patents may be competitive with our applications or conflict in certain respects with claims made under our applications. Such a conflict could result in a significant reduction of the coverage of our patents, if issued. In addition, if patents that contain competitive or conflicting claims are issued to others and such claims are ultimately determined to be valid, we may be required to obtain licenses to these patents or to develop or obtain alternative technology. If any licenses are required, there can be no assurance that we will be able to obtain any such licenses on commercially favorable terms, if at all. Our failure to obtain a license to any technology that we may require in order to commercialize our products could have a material adverse effect on our future business, financial condition and results of operations. Litigation, which could result in substantial

28


Table of Contents

cost to us, may also be necessary to enforce any patents issued to us or to determine the scope and validity of third party proprietary rights.

We also rely on secrecy to protect our technology, especially where patent protection is not believed to be appropriate or obtainable. We maintain strict controls and procedures regarding access to and use of our proprietary technology and processes. However, there can be no assurance that these controls or procedures will not be violated, that we would have adequate remedies for any violation, or that our trade secrets will not otherwise become known or be independently discovered by competitors.

Intense Competition; Uncertainty of Technological Change

Competition in the development of biopharmaceutical products is intense, both from biopharmaceutical and biotechnology companies, and is expected to increase. Many of our competitors have greater financial resources and larger research and development staffs than us, as well as substantially greater experience in developing products, obtaining regulatory approvals, and manufacturing and marketing biopharmaceutical products. Competition with these companies involves not only product development, but also acquisition of products and technologies from universities and other institutions. We also compete with universities and other institutions in the development of biopharmaceutical products, technologies and processes and for qualified scientific personnel. There can be no assurance that our competitors will not succeed in developing technologies and products that are more effective or affordable than those being developed by us. In addition, one or more of our competitors may achieve product commercialization of or patent protection for competitive products earlier than us, which would preclude or substantially limit sales of our products. Further, several companies are attempting to develop and market products to treat certain diseases based upon technology that would lessen or eliminate the need for human antibodies. The successful development and commercialization by any of our competitors of any such product could have a material adverse effect on our future business, financial condition and results of operations.

We compete for antibody donors with pharmaceutical companies, other independent antibody suppliers, other commercial collection companies and non-profit organizations such as the American Red Cross and community blood banks that solicit the donation of blood. A number of these competitors have access to greater financial, marketing and other resources than us. We compete for donors by offering financial incentives to donors to compensate them for their time and inconvenience, providing outstanding customer service to our donors, implementing programs designed to attract donors through education as to the uses for collected antibodies, encouraging groups to have their members become donors and improving the attractiveness of our antibodies collection facilities. We also compete with other independent antibody suppliers that sell antibodies principally to pharmaceutical companies that process antibodies into finished products. If we are unable to maintain and expand our donor base, our future business, financial condition and results of operations will be materially and adversely affected.

Uncertainty of Product Pricing and Reimbursement

Our ability to commercialize our biopharmaceutical products and related treatments will depend in part upon the availability of, and our ability to obtain adequate levels of, reimbursement from government health administration authorities, private healthcare insurers and other organizations. Significant uncertainty exists as to the reimbursement status of newly approved healthcare products, and there can be no assurance that adequate third party payer coverage will be available, if at all. Inadequate levels of reimbursement may prohibit us from maintaining price levels sufficient for realization of an adequate return on our investment in developing new biopharmaceutical products and could result in the termination of production of otherwise commercially viable products. Government and other third party payers are increasingly attempting to contain healthcare costs by limiting both the coverage and level of reimbursement for new products approved for marketing by the FDA and by refusing, in some cases, to provide any coverage for disease indications for which the FDA has not granted marketing approval. Also, the trend towards managed healthcare in the U.S. and the concurrent growth of organizations such as HMOs, which could control or significantly influence the purchase of healthcare services and products, as well as legislative proposals to reform healthcare or reduce government insurance

29


Table of Contents

programs, may all result in lower prices for our products. The cost containment measures that healthcare providers are instituting and the impact of any healthcare reform could have an adverse effect on our ability to sell our products and may have a material adverse effect on our future business, financial condition and results of operations.

There can be no assurance that reimbursement in the U.S. or foreign countries will be available for our products, or, if available, will not be decreased in the future, or that reimbursement amounts will not reduce the demand for, or the price of, our products. The unavailability of third party reimbursement or the inadequacy of the reimbursement for medical treatments using our products could have a material adverse effect on our future business, financial condition and results of operations. Moreover, we are unable to forecast what additional legislation or regulation, if any, relating to the healthcare industry or third party coverage and reimbursement may be enacted in the future or what effect such legislation or regulation would have on our future business.

ITEM 2. PROPERTIES

We own an 87,300 square foot facility that houses our executive offices and our licensed biopharmaceutical manufacturing facility in Boca Raton, Florida. We are currently constructing a 46,000 square foot facility in Boca Raton to house our laboratory and cold storage facility that is expected to replace our leased facilities in Miami, Florida in 2003.

We occupy antibody collection centers ranging in size from approximately 4,200 to 20,800 square feet leased from non-affiliates under leases expiring through 2012. A majority of these leases contain renewal options that permit us to renew the leases for varying periods up to ten years at the then fair rental value. We believe that in the normal course of our business, we will be able to renew or replace our existing leases.

We lease office, laboratory, warehouse and pilot manufacturing space in Miami, Florida and Rockville, Maryland with terms expiring through April 2007 with various options for lease extensions.

ITEM 3. LEGAL PROCEEDINGS

We are a party to litigation in the ordinary course of business. We do not believe that such litigation will have a material adverse effect on our future business, financial position or results of operations.

During 2002, we were named as one of over 40 pharmaceutical and biopharmaceutical defendants in three class action lawsuits, filed in the Superior Court of the State of California; two filed in the County of San Francisco on August 23, 2002 and September 9, 2002 and one filed in the County of Alameda on July 12, 2002. The cases each involve claims that insurers and consumers of defendants’ products made overpayments for those products based on an alleged manipulation of Average Wholesale Price (“AWP”), a standard which governs amounts that physicians, hospitals and other providers receive as reimbursement for purchases of defendants’ products. The plaintiffs seek damages, equitable relief and disgorgement of profits. The three lawsuits are in their preliminary stages; no class has been certified. To date, we have been served in only one of the three suits. The lawsuits do not allege that we collected monies from the putative plaintiffs. We believe that, to the extent the putative plaintiffs made any payments based on AWP, such payments were made to physicians, hospitals and other providers, not to us. We deny any liability and intend to vigorously defend the suits.

2002 as Compared to 2001

Sales. Biopharmaceutical sales increased in 2002 by approximately $16.0 million or 22% from 2001 sales. Sales of Nabi-HB® [Hepatitis B Immune Globulin (Human)] in 2002 increased approximately 36% from 2001 levels. These increased sales have been driven by the combined impact of increased patient demand for Nabi-HB and replenishment of the distribution channel inventory levels at wholesalers and distributors. During the second half of 2001 we reduced inventory levels of Nabi-HB at wholesalers and distributors in preparation for the transition to product manufactured at our Boca Raton manufacturing facility. Sales of product manufactured in our Boca Raton facility commenced in the first quarter of 2002. At December 28, 2002, we had back orders for Nabi-HB of approximately $3.5 million that we expect to fill in the first quarter of 2003. Sales of WinRho SDF® [Rho(D) Immune Globulin Intravenous (Human)] were essentially flat in 2002 compared to 2001. We report biopharmaceutical product sales when title and risk of loss are transferred to our wholesaler and distributor customers. In response to product supply shortages from the manufacturer of WinRho SDF in 2000, wholesaler and distributor inventory levels had increased in 2001. In 2002, with continued reliable product supply from the manufacturer, we established an internal goal of reducing inventory levels of WinRho SDF at our wholesaler and distributor customers. Our review of patient use data reports record levels of patient demand for WinRho SDF during 2002. This increased patient demand in 2002 has resulted in lower reported inventory levels of

37


Table of Contents

WinRho SDF at our pharmaceutical wholesaler and distributor customers. Sales of Autoplex® T [Anti-Inhibitor Coagulant Complex, Heat Treated] increased 57% in 2002 from 2001 levels, reflecting improved product supply from Baxter Healthcare Corporation (“Baxter”), the manufacturer of that product. Under terms of the acquisition agreement for Autoplex T, we could lose our rights to Autoplex T in May 2003 unless the Federal Trade Commission (“FTC”) extends these rights for an additional twelve months. The FTC could require us to return our rights to Autoplex T to Baxter if we do not obtain Food and Drug Administration (“FDA”) approval to manufacture the product by May 2003 or a later date agreed to by the FTC. Although we will not receive FDA approval to manufacture the product by May 2003, we anticipate that the FTC will extend our rights to Autoplex T through May 2004. Sales of Aloprim™ [(Allopurinol sodium) for injection] increased 62% due to the continuation of a positive trend for patient use of the product combined with receipt of back ordered product from DSM Pharmaceuticals, Inc., (formerly Catalytica Pharmaceuticals) (“DSM”), the manufacturer of Aloprim, in 2002. Sales of Aloprim and Autoplex T may be limited in 2003 due to product supply shortages.

Total antibody sales in 2002 decreased by $54.9 million, or 34%, compared to 2001. We expected this decrease following the sale of the majority of the antibody collection business and testing laboratory in September 2001. Non-specific antibody sales include shipments to a single customer under a supply contract that expires in May 2003, which was retained by us following the sale of the majority of the antibody collection business and testing laboratory. The purchaser of the majority of the antibody collection business and testing laboratory continues to supply us with non-specific antibodies to fulfill this obligation at the selling price under this contract. As a result, we did not record any margin under this arrangement. Because we retain the risk of credit loss with this customer, we record revenues on these sales. Such sales totaled $55.6 million in 2002. We do not intend to renew this contract upon its expiration. In 2002, sales of non-specific antibodies collected at our retained antibody collection centers totaled $18.2 million.

Gross profit margin. Gross profit margin for 2002 was $63.9 million, or 33% of sales, compared to $70.1 million, or 30% of sales in 2001. The higher proportion of biopharmaceutical product sales drove increased gross profit margin as a percentage of sales in 2002 compared to 2001. Offsetting the increased gross margin from biopharmaceutical products was the decreased gross profit margin from the antibody business we retained following the sale of the majority of our antibody collection business and testing laboratory in September 2001. Expenses related to excess manufacturing capacity in our Boca Raton facility impacted gross profit margin from biopharmaceutical product sales. The manufacturing capacity of the Boca Raton facility was not fully utilized in 2002, its first full year of operation. Excess plant capacity costs were $3.5 million in 2002 compared to $1.2 million in 2001. Excess plant capacity costs in 2001 were lower because they related to the fourth quarter of 2001 only, the plant’s initial period of operation. FDA licensure of the facility was received in October 2001. Excess plant capacity costs are expected to be incurred in 2003, although at a lower level than 2002, because we believe utilization of the Boca Raton facility will increase. Gross profit margin in each of 2002 and 2001 also benefited from non-performance penalty payments of $3.5 million and $6.1 million, respectively, as a result of contractual delivery shortfalls of Autoplex T from Baxter. The reduced non-performance penalties in 2002 compared to 2001 reflect improved product supply of Autoplex T from Baxter in 2002.

We incur royalty expense under our license and distribution agreements for WinRho SDF with Cangene Corporation (“Cangene”) and for Aloprim with DSM. Cangene and Nabi Biopharmaceuticals share equally in the profits from sales of WinRho SDF after accounting for the costs of production and selling expenses. Royalty expense includes Cangene’s share of profits under our license and distribution agreement. DSM and Nabi Biopharmaceuticals share equally in the profits of Aloprim after accounting for product costs and selling expenses on the first $4 million of product sales. On sales of Aloprim in excess of $4 million in a year, profits are shared 70% to us and 30% to DSM. Royalty expense includes DSM’s share of profits under our license and distribution agreement. In addition, royalty expense includes a 4% patent usage royalty related to the manufacturing process of Nabi-HB. Royalty expense in 2002 was $12.9 million, or 14% of biopharmaceutical product sales, compared to $12.1 million, or 16% of biopharmaceutical sales in 2001. Increased royalty expense in 2002 primarily reflected increased sales of Aloprim and Nabi-HB in 2002. Royalty expense related to WinRho SDF was slightly lower in 2002 compared to 2001, reflecting sales levels for WinRho SDF in each year.

38


Table of Contents

Selling, general and administrative expense. Selling, general and administrative expense was $38.4 million or 20% of sales in 2002, compared to $40.5 million or 17% of sales in 2001. General and administrative expense in 2002 included increased insurance and consulting expenses. These expense increases were more than offset by reductions in expenses, primarily compensation related expenses, following the sale of the majority of the antibody collection business and testing laboratory in September 2001 and through reimbursement that we received for certain administrative and support services we provided to the acquirer of the majority of the antibody collection business and testing laboratory during 2002. This reimbursement was recorded as an offset to selling, general and administrative expense. We expect the level of these administrative and support services to be reduced in 2003 compared to 2002. Our selling expense is primarily focused on the biopharmaceutical segment of our business and was not impacted by the sale of the majority of the antibody collection business and testing laboratory in September 2001.

Research and development expense. Research and development expense was $21.1 million or 11% of sales in 2002, compared to $15.3 million or 7% of sales in 2001. This increase is consistent with our strategic focus of generating a cash return from our currently marketed products to provide the resources to develop our research and development product pipeline. Approximately 46% of the research and development expense supported development of our Gram-positive infections program in 2002 compared to 49% in 2001. In 2002, we concluded a booster study for StaphVAX® (Staphylococcus aureus Polysaccharide Conjugate Vaccine) and incurred costs to continue transfer of the manufacturing process for StaphVAX to the facility of our proposed contract manufacturer of the product, Dow Biopharmaceuticals Contract Manufacturing Services (“Dow”). Material manufactured at this facility is expected to be used in the confirmatory Phase III clinical trial of StaphVAX anticipated to commence in the second half of 2003. In 2002, we also entered Civacir™ [Hepatitis C Immune Globulin (Human)] and NicVAX™ (Nicotine Conjugate Vaccine) into human clinical trials and completed a Biological License Application (“BLA”) filing for an intravenous formulation of Nabi-HB to prevent re-infection with hepatitis B in liver transplant patients. In January 2003, we were advised that the FDA has accepted this BLA for priority review, meaning that the FDA commits to responding to this BLA within 6 months, instead of the statutorily required 10 months. Research and development expense is expected to increase in 2003 from 2002 levels as we plan to commence the confirmatory Phase III clinical trial for StaphVAX, undertake Phase I/II clinical trials of NicVAX in smokers and ex-smokers both in the U.S. and Europe, commence a Phase II clinical study for Altastaph™ [Staphylococcus aureus Immune Globulin (Human)] in low birth weight newborns and continue to evaluate the steps required to transfer the manufacture of Autoplex T from Baxter to us.

Gain on disposition of assets. The gain on sale of assets reported in 2001 represents the excess of proceeds received from the sale of the majority of the antibody collection business and testing laboratory assets compared to their carrying values as of September 6, 2001, the effective date of the transaction.

Interest income. Interest income for 2002 was $1.3 million compared to $1.2 million in 2001. Interest income is earned from investing cash and cash equivalents on hand in money market funds and auction rate securities with maturities of three months or less placed with major financial institutions. In September 2001, we received proceeds of $135 million, net of repayment of then outstanding bank debt and closing costs, from the sale of the majority of the antibody collection business and testing laboratory, which were invested in these financial instruments. In April 2002, a portion of these funds was utilized to redeem our $78.5 million 6.5% Convertible Subordinated Notes (the “Notes”).

Interest expense. Interest expense was $2.1 million in each of 2002 and 2001. We redeemed $78.5 million of the Notes in April 2002 and incurred no interest expense on the Notes after that date. Interest expense for 2001 was net of the capitalization of incurred interest related to construction of our biopharmaceutical manufacturing facility in Boca Raton, Florida. We received licensure to manufacture Nabi-HB at our Boca Raton facility in October 2001 and ceased capitalization of interest and other costs at that time. Capitalized interest relating to construction of our biopharmaceutical manufacturing facility in Boca Raton, Florida was $5.2 million for 2001. In addition, our bank debt was repaid in September 2001 from a portion of the cash proceeds from the sale of the majority of the antibody collection business and testing laboratory.

Other factors. The provision for income taxes was $0.6 million for 2002, compared to $11.4 million in 2001. The 23% effective tax rate for 2002 differs from the statutory rate due primarily to utilization of research and development tax credits. The 10% effective tax rate for 2001 differs from the statutory rate due primarily to the reduction in the valuation allowance associated with utilization of net operating loss carryforwards.

2001 as Compared to 2000

Sales. Biopharmaceutical sales increased in 2001 by approximately $0.5 million or 1% from 2000 sales. Sales increases for WinRho SDF, which increased more than 35% from prior year levels, and Aloprim, were offset by decreased sales of Nabi-HB. Sales of Nabi-HB in 2001 decreased approximately 20% from 2000 levels. Sales of WinRho SDF were limited in 2000 due to product supply issues from the manufacturer of this product in that year. Patient use survey data reports growth in patient use of our major products, Nabi-HB and WinRho SDF, in 2001 compared to 2000. During 2001, this increased patient use of Nabi-HB resulted in lower inventory levels of this product at our pharmaceutical wholesaler customers. In addition, we reduced wholesaler inventory levels of Nabi-HB in anticipation of the launch of this product manufactured at our Boca Raton, Florida biopharmaceutical manufacturing facility in the first quarter of 2002. Our Boca Raton, Florida biopharmaceutical manufacturing facility received FDA approval to manufacture Nabi-HB in October 2001. As a result of product supply issues in 2000 limiting the supply of WinRho SDF, inventory levels at wholesalers and distributors increased at December 29, 2001 with improved product supply of the product. Sales of Autoplex T in 2001 and 2000 were limited by contractual product supply shortfalls from the manufacturer of that product.

Total antibody sales in 2001 increased by $5.6 million from 2000 levels driven by higher pricing for non-specific antibody products. These increased sales were achieved despite the sale of the majority of the antibody collection business in September 2001. Sales of specialty antibodies were approximately 19% lower in 2001 than in 2000 due primarily to the impact of the sale of the majority of the antibody collection business.

Gross profit margin. Gross profit margin for 2001 was $70.1 million, or 30% of sales, compared to $56.8 million or 25% of sales in 2000. The increase was due primarily to increased gross profit margin from antibody sales reflecting increased pricing for non-specific antibody products. Gross profit margin after royalty expense for the biopharmaceutical business was essentially even in each of 2001 and 2000. Gross margin from biopharmaceutical sales in 2001 reflects the operating costs of bringing the Boca Raton biopharmaceutical manufacturing facility on line following FDA licensure in October 2001. In its initial operation, the manufacturing capacity of the Boca Raton facility was not fully utilized and costs related to excess manufacturing capacity were expensed as cost of goods sold. In 2001, we recorded approximately $1.2 million of excess capacity costs. Gross profit margin in each of 2001 and 2000 also benefited from non-performance penalty payments of $6.1 million and $5.1 million, respectively, due to us as a result of contractual delivery shortfalls by the supplier of Autoplex T.

Royalty expense in 2001 was $12.1 million, or 16% of biopharmaceutical product sales, compared to $11.2 million, or 15% of biopharmaceutical sales in 2000. Increased royalty expense in 2001 primarily reflected increased sales of WinRho SDF in 2001 compared to 2000.

Selling, general and administrative expense. Selling, general and administrative expense was $40.5 million or 17% of sales in 2001, compared to $37.2 million or 16% of sales in 2000. The increase primarily reflects certain one time costs related to contractual severance payments, management consulting and legal expenses related to strategic initiatives and incentive compensation. Our sales and marketing expense relates primarily to the biopharmaceutical business and was not impacted by the sale of the majority of the antibody collection business and testing laboratory in September 2001.

Research and development expense. Research and development expense was $15.3 million or 7% of sales in 2001, compared to $14.3 million or 6% of sales in 2000. The increase in research and development expense primarily reflects increased support of our Gram-positive infections program including a boosting trial of StaphVAX in 77 end stage renal disease patients who received StaphVAX

during the pivotal Phase III trial reported in 2000, increased spending for Civacir including manufacture of Civacir clinical material in our biopharmaceutical manufacturing facility in Boca Raton in preparation for human clinical trials and increased spending for Autoplex T as we continue to evaluate the steps needed to transfer the manufacture of this product from its current manufacturer to us. During 2001, other significant research and development programs included Nabi-HB, primarily related to additional studies, and NicVAX, as we filed patent applications outside the U.S. In 2001 and 2000, approximately 49% and 48%, respectively, of the total research and development expense were expended to support advancing our Gram-positive infections program, including StaphVAX and Altastaph.

Gain on disposition of assets. The gain on sale of assets reported in the third quarter of 2001 represents the excess of proceeds received from the sale of the majority of the antibody collection business and testing laboratory assets compared to their carrying values as of September 6, 2001, the effective date of the transaction.

Non-recurring credit. During 2000, we reversed restructuring accruals totaling $3.9 million into income. This was reported as a non-recurring credit.

Interest income. Interest income for 2001 was $1.2 million compared to $33 thousand in 2000. Increased interest income reflects interest income from the net cash proceeds received from the sale of the majority of the antibody collection business and testing laboratory in September 2001. After elimination of bank debt, we had approximately $131 million in cash and cash equivalents on hand at September 29, 2001.

Interest expense. Interest expense for 2001 was $2.1 million, compared to $3.6 million in 2000. The decrease in interest expense is attributable to the elimination of bank debt in September 2001 as a result of the sale of the majority of the antibody collection business and lower bank interest rates offset by the reduction in capitalized interest during 2001. Capitalized interest relating primarily to construction of our biopharmaceutical manufacturing facility in Boca Raton, Florida was $5.2 million for 2001 as compared to $5.8 million for 2000. We received licensure to manufacture Nabi-HB at our Boca Raton facility in October 2001 and ceased capitalization of interest and other costs at that time.

Other (expenses) income, net. During 2000, we exchanged an aggregate of 241,795 shares of our common stock for an aggregate of $2.0 million of our 6.5% Convertible Subordinated Notes due 2003. The subsequent extinguishment of the Notes resulted in a gain of $0.4 million that is included in other income for 2000.

Other factors. The provision for income taxes was $11.4 million for 2001, compared to $0.1 million in 2000. The provision for income taxes in 2001 included changes in the estimated values of deferred tax assets and liabilities and the impact of stock option exercises during the year. The 10% effective tax rate for 2001 differs from the statutory rate due primarily to the reduction in the valuation allowance associated with utilization of net operating loss carryforwards.

Liquidity and Capital Resources

Our cash and cash equivalents at December 28, 2002 were $51.7 million.

Cash provided by operations for the year ended December 28, 2002 was $10.9 million primarily reflecting results of our operations offset by decreases in accrued expenses following settlement of an arbitration proceeding with Baxter related to 2001 antibody operations and the settlement of accrued interest paid in February 2002 in accordance with the provisions of our Notes.

Capital expenditures of $5.7 million for the year ended December 28, 2002 primarily related to capital investments in our Rockville, Maryland research and development operations, antibody center operations and computer information systems. In 2003, we plan to make capital expenditures of approximately $8 million, including $3.2 million to construct laboratory and cold storage facilities on our property in Boca Raton, Florida.

In May 2000, we completed agreements with Dow for the contract production and commercial supply of StaphVAX. In accordance with terms of these agreements, we paid $6.2 million in 2002 related to the acquisition of a Manufacturing Right at the Dow facility that will be used to manufacture StaphVAX at commercial scale. The acquired Manufacturing Right is recorded in Intangible Assets in our financial statements. The original contract to ready the Dow facility to manufacture StaphVAX, which was scheduled to expire in October 2002, has been extended to March 2003. We expect to sign an amended contract with Dow to complete readying the facility for its intended use, the commercial manufacture of StaphVAX. This modification will require us to make significant additional payments to Dow expected to be in excess of $15 million relating to the acquisition of the Manufacturing Right in 2003. We also expect to have a right to cancel the amended Dow agreements for a limited period after the amendments are executed.

In April 2002, we redeemed the Notes in the aggregate principal amount of $78.5 million. This redemption resulted in a reduction in interest expense of $3.7 million for 2002 compared to if the Notes had been retained until their original maturity.

During 2002, we received $1.2 million from the exercise of employee stock options.

On September 19, 2001, our Board of Directors approved the expenditure of up to $5.0 million to repurchase shares of our common stock in the open market or in privately negotiated transactions. Repurchases will allow us to have treasury stock available to support our stock option and stock purchase programs. In the year ended December 28, 2002, we acquired 171,483 shares of Nabi Biopharmaceuticals stock for $0.9 million under this program. In total we have acquired 345,883 shares of Nabi Biopharmaceuticals stock, for a total of $1.9 million, since the inception of this stock buy back program. Repurchased shares have been accounted for as treasury stock. We will evaluate market conditions in the future and make decisions to repurchase additional shares of our common stock on a case-by-case basis in accordance with our Board of Directors’ approval.

On December 12, 2002, our bank line of credit agreement expired. We intend to enter into a new credit facility in 2003.

We believe that cash flow from operations and cash and cash equivalents on hand, together with our ability to borrow funds should the need arise, will be sufficient to meet our anticipated cash requirements for operations for at least the next twelve months.

Below is a schedule of our current contractual obligations and commercial commitments as of December 28, 2002 for the specified fiscal years exclusive of our anticipated additional payment obligations to Dow:

Critical Accounting Estimates

The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of sales and expenses during the reporting period. Actual results could differ from those estimates.

Accounts Receivable and Revenue Recognition

In the year ended December 28, 2002, we had biopharmaceutical product sales of $89.5 million. At December 28, 2002 we had $36.3 million of accounts receivable including $22.2 million from biopharmaceuticals sales. Our primary customers for biopharmaceutical products are pharmaceutical wholesalers. In accordance with our revenue recognition policy, revenue from biopharmaceutical product sales is recognized when title and risk of loss are transferred to the customer. Reported sales are net of estimated customer prompt pay discounts, contractual allowances in accordance with managed care agreements, government payer rebates and other wholesaler fees. At December 28, 2002 we had $3.9 million recorded in other current liabilities related to these contractual obligations as accrued sales deductions.

Property, Plant and Equipment and Depreciation

We incurred $90.3 million to construct our biopharmaceutical manufacturing facility in Boca Raton, Florida and received approval to manufacture our own antibody-based biopharmaceutical product, Nabi-HB, at this facility from the FDA in October 2001. In constructing the facility for its intended use, we incurred approximately $26.8 million in direct costs of acquiring the building, building systems, manufacturing equipment and computer systems. We also incurred a total of $63.5 million of costs related to validation of the facility to operate in a FDA approved environment and capitalized interest. Costs related to validation and capitalized interest have been allocated to the building, building systems, manufacturing equipment and computer systems. Buildings and building systems are depreciated on a straight-line basis over 39 years and 20 years, respectively, the estimated useful lives of these assets. The specialized manufacturing equipment and computer systems are depreciated using the units-of-production method of depreciation subject to a minimum level of depreciation based on straight-line depreciation. The units-of-production method of depreciation is based on management’s estimate of production levels. Management believes the units-of-production method is appropriate for these specialized assets. Use of the units-of-production method of depreciation may result in significantly different financial results of operation than straight-line depreciation in periods of lower than average or higher than average production levels. However, this differential is limited in periods of lower than average production, as we record a minimum of 60% of the depreciation that would have otherwise been recorded had we used the straight-line method. In 2002 we recorded additional depreciation of $2.3 million under this policy.

Intangible Assets

In 2000, we entered into contract manufacturing agreements with Dow to establish commercial manufacturing capability for StaphVAX. The manufacturing process for StaphVAX is being transferred to Dow from our pilot manufacturing plant in Rockville, Maryland. We plan to use StaphVAX material from initial clinical lots manufactured at Dow under current Good Manufacturing Practices (“cGMP”) for an immunogenicity study and for the confirmatory Phase III trial planned to commence in 2003. We expect Dow to complete scale-up of manufacturing at the facility and to begin the production of consistency lots of StaphVAX in 2004. The contract manufacturing agreements required us to make certain payments to Dow to secure future access to commercial vaccine manufacturing capacity and to enable Dow to ready its facility for the future commercial scale manufacture of StaphVAX, its intended use. These payments have been recorded as a Manufacturing Right and included in Intangible Assets. Amortization of the Manufacturing Right is expected to commence when commercial manufacture of StaphVAX commences at Dow. Management believes that we will manufacture StaphVAX at Dow’s facility at commercial scale in future periods. If we determine that manufacture of StaphVAX will not occur at Dow’s facility, we will

43


Table of Contents

write off the Manufacturing Right in the period of that determination. As of December 28, 2002, the Manufacturing Right was $10.9 million and it is expected to increase in 2003.

Inventory and Reserves for Slow Moving or Obsolete Inventory

At December 28, 2002, we had inventory on hand of $19.4 million. In the year ended December 28, 2002 we recorded a provision for inventory valuation allowance of $0.7 million. We review inventory on hand at each reporting period to assess that inventory is stated at the lower of cost or market and that inventory on hand is saleable. Our assessment of inventory includes review of selling price compared to inventory carrying cost, recent sales trends and our expectations for sales trends in future periods and product shelf life expiration. Based on these assessments, we provide for an inventory valuation allowance in the period in which the requirement is identified.

New Accounting Pronouncements

In June 2001, the Financial Accounting Standards Board (“FASB”) issued Statement of Financial Accounting Standards (“SFAS”) No. 143, Accounting for Asset Retirement Obligations, which is effective for fiscal years beginning after June 15, 2002. SFAS 143 requires legal obligations associated with the retirement of long-lived assets to be recognized at their fair value at the time the obligations are incurred. Upon initial recognition of a liability, that cost should be capitalized as part of the related long-lived asset and allocated to expense over the useful life of the asset. Application of the new rules is not expected to have a significant impact on our financial position and results of operations.

In August 2001, the FASB issued SFAS No. 144, Accounting for the Impairment or Disposal of Long-Lived Assets, which addresses financial accounting and reporting for the impairment or disposal of long-lived assets and supercedes SFAS No. 121, Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed Of, and the accounting and reporting provisions of Accounting Principles Board (“APB”) Opinion No. 30, Reporting the Results of Operations for a Disposal of a Segment of a Business. SFAS 144 is effective for fiscal years beginning after December 15, 2001. Adoption of SFAS 144 did not have a significant impact on our financial position and results of operations.

In April 2002, the FASB issued SFAS No. 145, Rescission of FASB Statements No. 4, 44, and 62, Amendment of FASB Statement No. 13, and Technical Corrections. SFAS 145 requires gains and losses on extinguishments of debt to be classified as income or loss from continuing operations rather than as extraordinary items as previously required under SFAS 4. Extraordinary treatment will be required for certain extinguishments as provided in APB Opinion No. 30. SFAS 145 is effective for all fiscal years beginning after May 15, 2002 and has been adopted by us in fiscal 2003. Adoption of SFAS 145 resulted in a change in our classification of an extraordinary gain related to the early extinguishment of debt for the fiscal year ended December 30, 2000 to other income.

In June 2002, the FASB issued SFAS No. 146, Accounting for Costs Associated with Exit or Disposal Activities. This Statement requires that we record costs associated with exit or disposal activities at their fair values when a liability has been incurred. Under previous guidance, certain exit costs were accrued upon management’s commitment to an exit plan, which is generally before an actual liability has been incurred. We were required to adopt SFAS 146 on December 29, 2002. We do not expect the adoption to have a material affect on our cash flows or the results of our operations.

In December 2002, the FASB issued SFAS No. 148, Accounting for Stock-Based Compensation — Transition and Disclosure an amendment of FASB Statement No. 123. This Statement amends SFAS No. 123, Accounting for Stock-Based Compensation, to provide alternative methods of transition for an entity that voluntarily changes to the fair value based method of accounting for stock-based employee compensation. It also amends the disclosure provisions of that Statement to require prominent disclosure about the effects on reported net income of an entity’s accounting policy decisions with respect to stock-based employee compensation. Finally, this Statement amends APB Opinion No. 28, Interim Financial Reporting, to require disclosure about those effects in interim financial information. We intend to continue to account for stock-based compensation based on the

44


Table of Contents

provisions of APB Opinion No. 25. SFAS 148’s amendment of the transition and annual disclosure provisions of SFAS 123 are effective for fiscal years ending after December 15, 2002, and the disclosure requirements for interim financial statements are effective for interim periods beginning after December 15, 2002. We will adopt the disclosure provisions of SFAS 148 beginning in the quarter ending March 29, 2003.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We do not engage in trading market risk sensitive instruments or purchasing hedging instruments or “other than trading” instruments that are likely to expose us to significant market risk, whether interest rate, foreign currency exchange, commodity price or equity price risk.

Interest Rate Risk. At December 28, 2002, we had cash and cash equivalents in the amount of $51.7 million. Cash equivalents consist of money market funds and auction rate securities with maturities of three months or less placed with major financial institutions.

Our exposure to market risk is confined to our cash and investments. We maintain an investment portfolio of money market funds, qualified purchaser funds, and auction rate securities. The securities in our investment portfolio are not leveraged, and are, due to their very short-term nature, subject to minimal interest rate risk. We currently do not hedge interest rate exposure. Because of the short-term maturities of our investments, we do not believe that a change in market rates would have a significant negative impact on the value of our investment portfolio.

The primary objective of our investment activities is to preserve principal while at the same time maximizing yields without significantly increasing risk. To achieve this objective, we invest our excess cash in debt instruments of the U.S. Government and its agencies, bank obligations, repurchase agreements and high-quality corporate issuers, and, by policy, restrict our exposure to any single corporate issuer by imposing concentration limits. To minimize the exposure due to adverse shifts in interest rates, we maintain investments at an average maturity of generally less than one month.

The table below presents the principal amount and weighted-average interest rate for our investment portfolio:

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1 BUSINESS AND ORGANIZATION

Nabi Biopharmaceuticals discovers, develops, manufactures and markets products that power the immune system to help people with serious, unmet medical needs. We have a broad product portfolio and significant research capabilities focused on developing and commercializing novel vaccines and antibody-based biopharmaceutical products that prevent and treat infectious, autoimmune and addictive diseases, such as hepatitis B, hepatitis C and Staphylococcus aureus infections, immune thrombocytopenia purpura (“ITP”) and nicotine addiction. We have four marketed products, Nabi-HB® [Hepatitis B Immune Globulin (Human)] for the prevention of hepatitis B infections, WinRho SDF® [Rho(D) Immune Globulin Intravenous (Human)] for the treatment of acute, chronic and HIV-related ITP, Autoplex® T [Anti-Inhibitor Coagulant Complex, Heat Treated] and Aloprim™ [(Allopurinol sodium) for injection]. We have a significant clinical trials program including clinical trials of our lead investigational products, StaphVAX® (Staphylococcus aureus Polysaccharide Conjugate Vaccine), Altastaph™ [Staphylococcus aureus Immune Globulin (Human)], Civacir™ [Hepatitis C Immune Globulin (Human)] and NicVAX™ (Nicotine Conjugate Vaccine). We have a state-of-the-art fractionation facility for the manufacture of Nabi-HB and our investigational antibody products and for contract manufacturing. Further, we also collect specialty and non-specific antibodies for use in our products as well as to supply pharmaceutical and diagnostic customers for the subsequent production of their products.

NOTE 2 SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Principles of consolidation: The consolidated financial statements include the accounts of Nabi Biopharmaceuticals and its wholly owned subsidiaries. All significant intercompany accounts and transactions are eliminated in consolidation.

Accounting estimates: The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of sales and expenses during the reporting period. Actual results could differ from those estimates.

Basis of presentation: Certain items in the 2001 and 2000 consolidated financial statements have been reclassified to conform to the current year’s presentation.

Revenue recognition: Revenue from product sales is recognized when title and risk of loss are transferred to the customer. Cash collections in excess of amounts earned on billings are recorded as deferred revenue and recognized as services are rendered or products are shipped. Revenue from biopharmaceutical product sales is reported net of customer prompt pay discounts, contractual allowances in accordance with our managed care agreements, government payer rebates and other wholesaler fees.

Research and development expense: Research and development costs are expensed as incurred. Amounts payable to third parties under collaborative product development agreements are recorded at the earlier of the milestone achievement or as payments become contractually due. Funding from third party grants are applied directly to related expenses.

Advertising expenses: Advertising costs are expensed as incurred as set forth in Statement of Position 93-7, Reporting on Advertising Costs. Advertising expenses for the years ended December 28, 2002,

52


Table of Contents

December 29, 2001 and December 30, 2000 amounted to $3.4 million, $3.4 million and $5.0 million, respectively.

Shipping and Handling Costs: We report costs related to the shipment of our product as part of other operating expenses, principally freight and amortization. We incurred $0.6 million, $0.7 million and $0.7 million in the years ended December 28, 2002, December 29, 2001 and December 30, 2000, respectively.

Earnings per share: Basic earnings per share is computed by dividing consolidated net earnings by the weighted average number of common shares outstanding during the year. Diluted earnings per share is computed by dividing consolidated net earnings by the weighted average number of common shares outstanding, and the impact of all potential dilutive common shares, primarily stock options. The dilutive impact of stock options is determined by applying the treasury stock method.

Financial instruments: The carrying amounts of financial instruments including cash equivalents, short-term investments, accounts receivable and accounts payable approximated fair value as of December 28, 2002 and December 29, 2001, because of the relatively short-term maturity of these instruments. Information regarding long-term debt is included in Note 8.

Cash equivalents consist of money market funds and auction rate securities with maturities of three months or less placed with major financial institutions.

We sell a significant portion of our products through pharmaceutical wholesalers and distributors and major pharmaceutical companies and, as a result, maintain individually significant receivable balances with major customers. If the financial condition or operations of these customers were to deteriorate, our results could be adversely affected. Credit terms to these customers generally range from 30 to 60 days. We evaluate and monitor the credit worthiness of each customer on a case-by-case basis. Allowances are maintained for potential credit losses. Accounts receivable allowances are recorded in the segment operating results in which the applicable sale was originally reported.

Inventories: Inventories are stated at the lower of cost or market with cost determined on the first-in first-out (“FIFO”) method.

Property, plant and equipment: Property, plant and equipment are carried at cost. Depreciation is generally recognized on the straight-line method over the estimated useful lives of the assets.

Depreciation for certain specialized production equipment in our Boca Raton, Florida biopharmaceutical manufacturing facility is calculated over their remaining useful lives using the units-of-production method. In quarters of lower production, we record a minimum of 60% of the depreciation that would have otherwise been recorded had we used the straight-line method. We evaluate the remaining lives and recoverability of this equipment periodically based on the appropriate facts and circumstances.

Depreciable lives of property and equipment are as follows:

     
Asset   Life

 
Buildings   35 — 39 Years
Building systems   20 Years
Furniture and fixtures   5 — 8 Years
Information systems   3 — 7 Years
Machinery and equipment   3 — 8 Years
Leasehold improvements   Lesser of lease term or economic life

Table of Contents

Intangible assets: Intangible assets represent the fair values of certain assets acquired in product acquisitions including trademarks and trademark registrations and the cost to acquire the right to use manufacturing capacity at our contract manufacturer for StaphVAX in future periods. The carrying costs of intangible assets are amortized ratably from the date placed into service over periods ranging from 3 to 25 years and are evaluated for recoverability at least annually.

Impairment of Long-Lived Assets: Pursuant to the provisions of Statement of Financial Accounting Standards (“SFAS”) No. 144, Accounting for the Impairment or Disposal of Long-Lived Assets, we review long-lived assets for impairment at least annually, or whenever events or changes in circumstances indicate that the carrying amount of such assets may not be fully recoverable. If this review reveals indications of impairment, as generally determined based on estimated undiscounted cash flows, the carrying amount of the related long-lived assets are adjusted to fair value.

Stock-Based Compensation: We account for our stock-based compensation plans using the intrinsic value method prescribed in Accounting Principles Board (“APB”) Opinion No. 25, “Accounting for Stock Issued to Employees,” and related interpretations. Note 9 contains a summary of the pro forma effects to reported net income and earnings per share for 2002, 2001 and 2000 as if we had elected to recognize compensation expense based on the fair market value of the options at their grant date as prescribed by SFAS No. 123, “Accounting for Stock-Based Compensation.”

New Accounting Pronouncements: In June 2001, the Financial Accounting Standards Board (“FASB”) issued SFAS No. 143, Accounting for Asset Retirement Obligations, which is effective for fiscal years beginning after June 15, 2002. SFAS 143 requires legal obligations associated with the retirement of long-lived assets to be recognized at their fair value at the time the obligations are incurred. Upon initial recognition of a liability, that cost should be capitalized as part of the related long-lived asset and allocated to expense over the useful life of the asset. Application of the new rules is not expected to have a significant impact on our financial position and results of operations.

In August 2001, the FASB issued SFAS No. 144, Accounting for the Impairment or Disposal of Long-Lived Assets, which addresses financial accounting and reporting for the impairment or disposal of long-lived assets and supercedes SFAS No. 121, Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed Of, and the accounting and reporting provisions of APB Opinion No. 30, Reporting the Results of Operations for a Disposal of a Segment of a Business. SFAS 144 is effective for fiscal years beginning after December 15, 2001. Adoption of SFAS 144 did not have a significant impact on our financial position and results of operations.

In April 2002, the FASB issued SFAS No. 145, Rescission of FASB Statements No. 4, 44, and 62, Amendment of FASB Statement No. 13, and Technical Corrections. SFAS 145 requires gains and losses on extinguishments of debt to be classified as income or loss from continuing operations rather than as extraordinary items as previously required under SFAS 4. Extraordinary treatment will be required for certain extinguishments as provided in APB Opinion No. 30. SFAS 145 is effective for all fiscal years beginning after May 15, 2002 and has been adopted by us in fiscal 2003. Adoption of SFAS 145 resulted in a change in our classification of an extraordinary gain related to the early extinguishment of debt for the fiscal year ended December 30, 2000 to other income.

In June 2002, the FASB issued SFAS No. 146, Accounting for Costs Associated with Exit or Disposal Activities. This Statement requires that we record costs associated with exit or disposal activities at their fair values when a liability has been incurred. Under previous guidance, certain exit costs were accrued upon management’s commitment to an exit plan, which is generally before an actual liability has been incurred. We are required to adopt SFAS 146 on December 29, 2002. We do not expect the adoption to have a material affect on our cash flows or the results of our operations.

In December 2002, the FASB issued SFAS No. 148, Accounting for Stock-Based Compensation — Transition and Disclosure an amendment of FASB Statement No. 123. This Statement amends

54


Table of Contents

SFAS No. 123, Accounting for Stock-Based Compensation, to provide alternative methods of transition for an entity that voluntarily changes to the fair value based method of accounting for stock-based employee compensation. It also amends the disclosure provisions of that Statement to require prominent disclosure about the effects on reported net income of an entity’s accounting policy decisions with respect to stock-based employee compensation. Finally, this Statement amends APB Opinion No. 28 Interim Financial Reporting, to require disclosure about those effects in interim financial information. We intend to continue to account for stock-based compensation based on the provisions of APB Opinion No. 25. SFAS 148’s amendment of the transition and annual disclosure provisions of SFAS 123 are effective for fiscal years ending after December 15, 2002, and the disclosure requirements for interim financial statements are effective for interim periods beginning after December 15, 2002. We will adopt the disclosure provisions of SFAS 148 beginning in the quarter ending March 29, 2003.

Property, plant and equipment, net
  $ 103,706     $ 107,866  
 
   
     
 

We received FDA licensure to manufacture Nabi-HB at our biopharmaceutical manufacturing facility in Boca Raton, Florida in October 2001. Capitalization of interest and other costs ceased at that time and the facility was placed into service. Total costs of construction of the Boca Raton facility, including the building, building systems, plant equipment and information systems were approximately $90.3 million. Validation costs and capitalized interest related directly to preparing the facility for its intended use totaled $63.5 million. Interest capitalized in association with the manufacturing facility and systems development projects amounted to $5.2 million and $5.8 million during 2001 and 2000, respectively.

Depreciation and amortization expense of property, plant and equipment during 2002, 2001 and 2000 was $9.6 million, $7.8 million and $7.8 million, respectively. Depreciation expense related to the initial operation of our biopharmaceutical manufacturing facility in Boca Raton, Florida commenced in October 2001 and is included in depreciation expense for 2002. In accordance with our depreciation policy for certain specialized equipment in our biopharmaceutical facility, we recorded additional depreciation expense of $2.3 million due to the units-of-production method of depreciation resulting in depreciation less than at least 60% of depreciation expense that would be recorded using the straight-line method of depreciation for this equipment.

During 2002, we wrote off and disposed of equipment with a cost of $2.6 million and accumulated depreciation of $2.3 million.

Construction in process at December 28, 2002 included initial costs related to the construction of a laboratory and cold storage facility in Boca Raton, Florida.

Accrued contract settlement at December 29, 2001 represented the settlement of an arbitration proceeding with Baxter Healthcare Corporation (“Baxter”) related to antibody supply. Amounts accrued under the terms of this settlement were paid in full during 2002.

Accrued interest at December 29, 2001 represented interest due and paid on February 1, 2002 in accordance with the terms of the 6.5% Convertible Subordinated Notes which were redeemed in full in April 2002.

There was no long-term or short-term indebtedness outstanding at December 28, 2002. On December 12, 2002, our bank line of credit agreement expired.

During 1996, we issued $80.5 million of 6.5% Convertible Subordinated Notes in a private placement. On April 8, 2002, we redeemed the outstanding 6.5% Notes in the aggregate principal amount of $78.5 million. The Notes were redeemed for cash at 100% of the principal balance plus accrued interest through April 8, 2002. The Notes had an original maturity date of February 1, 2003. In conjunction with this redemption, we wrote off $0.4 million of loan origination fees in 2002.

NOTE 9 STOCKHOLDERS’ EQUITY

Warrants

In July 2000, we issued a warrant to purchase 133,333 shares of common stock to our agent in connection with the private placement of common stock for which we realized $9.3 million, net of issuance costs. The warrant has an exercise price of $7.50 and expires in July 2005. The estimated fair value of the warrant at the date of grant was $0.9 million. This fair value was calculated using the Black-Scholes model with the following assumptions: expected term of five years, expected volatility of 104% and expected risk-free interest rate of 6%.

Treasury Stock

In September 2001, our Board of Directors approved the expenditure of up to $5.0 million to purchase our common stock in the open market or in privately negotiated transactions. Repurchases will allow us to have treasury stock available to support our stock option and Employee Stock Purchase Programs (“ESPP”). During 2002 and 2001, we acquired 171,483 and 174,400 shares of Nabi Biopharmaceuticals stock for approximately $0.9 million and $1.0 million, respectively, under this program and have accounted for the acquired stock as treasury stock.

In a transaction dated March 28, 2002, one of our officers exercised stock options for 60,000 shares of our stock. The purchase price was paid by delivery of 40,107 shares of common stock, valued at $0.2

Table of Contents

million, which the officer had acquired more than six months earlier. These shares have been accounted for as treasury stock.

Stock Options

We maintain four stock option plans for our employees. Under these plans, we have granted options to certain employees entitling them to purchase shares of common stock within ten years. The options vest over periods ranging from zero to four years from the date of grant and have been granted at exercise prices equal to the fair market value of the underlying common stock on the date of grant.

Related to the sale of the operating assets of a majority of our antibody collection business and our testing laboratory in September 2001, the Board of Directors approved the extension of the exercise period after termination of employment from 90 days to four years for vested options held by employees whose positions were terminated by us in the transaction. As a result of this modification, we recognized a $1.2 million compensation expense reflecting the difference on the date of modification between the fair market value of shares subject to options that had vested and the exercise price of the vested options.

We also maintain a Stock Option Plan for Non-Employee Directors, under which we have granted options to certain directors entitling them to purchase shares of common stock within five years, vesting six months after the date of grant at an exercise price equal to the fair market value of the underlying common stock at the date of grant.

At December 28, 2002, there were options outstanding under all of our stock plans to acquire 8.0 million shares of our common stock of which 4.8 million were then exercisable. Additionally, 11.2 million shares of common stock are reserved for future grants under the plans.

Stock options granted and outstanding under these plans as of December 28, 2002 are presented below:

The estimated fair value of each option grant is determined using the Black-Scholes option-pricing model with the following ranges of assumptions: expected term of two to four years; expected volatility of 83-100%; and expected risk-free interest rates of 2-7%. The weighted-average estimated fair value of options granted during 2002, 2001 and 2000 were $5.76, $3.58 and $4.95, respectively.

Employee Stock Purchase Plan

In May 2000, the stockholders approved the 2000 Employee Stock Purchase Plan (“ESPP”). The terms of the ESPP allow for qualified employees (as defined therein) to participate in the purchase of up to 500,000 shares of our common stock at a price equal to 85% of the lower of the closing price at the beginning or end of each semi-annual stock purchase period. We issued 116,940, 130,001 and 76,973 shares of common stock during 2002, 2001 and 2000, respectively, pursuant to this plan at an average price per common share of $4.99, $4.51 and $4.04, respectively.

Shareholders Rights Plan

Effective July 1997, our Board of Directors adopted a shareholders rights plan under which a dividend of one preferred share purchase right (the “Right”) was distributed for each outstanding share of common stock. Each right entitles the holder to purchase one one-hundredth of a share of Series One Preferred Stock at a price of $70, subject to adjustment. The Rights expire in August 2007, and are exercisable only if an individual or group has acquired or obtained the right to acquire, or has announced a tender or exchange offer that if consummated would result in such individual or group acquiring beneficial ownership of 15% or more of the common stock. Such percentage may be lowered at the Board’s discretion. If the Rights become exercisable, the holder (other than the individual or group who triggered the exercisability) may be entitled to receive upon exercise shares of our common stock having a market

value of two times the exercise price of the Rights, or the number of shares of the acquiring company which have a market value of two times the exercise price of the Rights. The Rights separate from the common stock if they become exercisable. We are entitled to redeem the Rights in whole for $0.01 per Right under certain circumstances.

Shares of Common Stock

As of December 28, 2002, 11.5 million shares of common stock in the aggregate were reserved for issuance related to stock options, warrants and employee benefit plans.

NOTE 10 SALE OF ASSETS

On September 6, 2001, we sold the operating assets of a majority of our antibody collection business and testing laboratory for $156.3 million in cash. The assets sold were certain real estate, leasehold interests, fixtures, furniture, tools, machinery and equipment, other fixed assets, antibody inventories and related supplies, contracts, agreements, arrangements and/or commitments, licenses and permits, business and financial records, intellectual property and goodwill related to the operation of the 47 antibody collection centers and our testing laboratory included in the transaction.

The following is a summary of the components of the gain on the sale of assets:

We were advised in the transaction by an investment bank, the president of which is a member of our Board of Directors. The investment bank’s services were utilized due to its specific experience in our industry. We believe the professional fees paid of $1.5 million were commensurate with market rates for such services in this type of transaction.

NOTE 11 NON-RECURRING CHARGES

During 1998, we recorded a non-recurring charge that included $13.2 million related to a strategic plan to sell or close certain antibody collection centers and actions to reduce pre-clinical product development activities at our Rockville, Maryland facility. During 1999, we reduced staff levels at our Rockville facility, closed or sold seven U.S. antibody collection centers out of the eight centers specified in the original plan, and transferred our four German antibody collection centers and related operations to a third party.

Based on the positive results from the StaphVAX Phase III trial announced in September 2000 and the approval of a plan in 2000 to increase the level of research and development activities in the future at our Rockville, Maryland facility, we reversed $3.0 million of the remaining non-recurring charge accrual into income. This was reported as a non-recurring credit in our income statement.

61


Table of Contents

The balance of the restructuring accrual was comprised of anticipated shut-down and severance costs related to the scheduled closure of an antibody collection center in the original plan. In the third quarter of 2000, we determined that operations would continue at this center for the foreseeable future and the center continued in operation. Based on this change to the original operating plan, the remaining accrual of $0.9 million was reversed into income during the third quarter of 2000 and reported as a non-recurring credit. This antibody collection center was included in the centers sold as part of the sale of the majority of the antibody collection business and testing laboratory in September 2001.

Approximately $4.3 million of the net operating loss carryforwards are related to the exercise of employee stock options, and we will record a tax benefit of approximately $1.6 million through capital in excess of par value when losses are realized.

We have research and development tax credit carryforwards of $5.7 million that expire in varying amounts through 2022. We have alternative minimum tax credit carryforwards of $0.9 million that are available to offset future regular tax liabilities, and do not expire.

The ultimate realization of the remaining deferred tax assets is largely dependent on our ability to generate sufficient future taxable income. Management has determined that no valuation allowance is necessary for the years ended December 28, 2002 and December 29, 2001.

NOTE 14 EMPLOYEE BENEFIT PLANS

Effective December 31, 2001, the discretionary company match for employee contributions to the Nabi Savings and Retirement Plan (the “Plan”) was changed to 4% of the participant’s earnings commencing in 2002. The plan permits employees to contribute up to 15% of pre-tax annual compensation. In 2001 and 2000, there were two defined plans with a discretionary match by the company equal to 50% of each participant’s contribution, up to an amount equal to 2% of the participant’s earnings. Effective December 31, 2001, these two plans were merged into the Plan. Our matching contributions to the plans were approximately $1.0 million in 2002, $0.4 million in 2001 and $0.5 million 2000.

NOTE 15 LEASES

We conduct certain of our operations under operating lease agreements. The majority of these lease agreements contain renewal options which enable us to renew the leases for periods of two to ten years at the then fair rental value at the end of the initial lease term.

Rent expense was approximately $3.8 million, $6.6 million and $7.2 million for the years ended December 28, 2002, December 29, 2001 and December 30, 2000, respectively. The decrease in rent expense in the year ended December 28, 2002 compared to the years ended December 29, 2001 and December 30, 2000, respectively, is due to the effect of the sale of the majority of the antibody collection business and testing laboratory in September 2001.

As of December 28, 2002, the aggregate future minimum lease payments under all non-cancelable operating leases with initial or remaining lease terms in excess of one year are as follows:

NOTE 16 RELATED PARTY TRANSACTIONS

At December 29, 2001, notes receivable from corporate officers aggregated $162,000 at an interest rate equal to the prime interest rate. Repayment in full was made in the first quarter of 2002 and there are no amounts receivable from corporate officers at December 28, 2002.

In 2001, we engaged an investment bank, the president of which is a member of our Board of Directors, to provide certain services to us in connection with our review and implementation of a corporate expansion strategy. This engagement, which may be terminated by either party upon thirty days notice, currently provides for a monthly retainer of $30,000 and additional fees under certain circumstances. During 2002 and 2001 we paid this investment bank $628,000 and $100,000, respectively, including expenses, under this engagement. We believe the terms of the engagement are no less favorable to us

than would have been obtained from an unrelated party. This investment bank also advised us and received a fee in connection with the sale of the majority of the antibody collection business and testing laboratory. Refer to Note 10.

NOTE 17 STRATEGIC ALLIANCES, LICENSES AND ROYALTY AGREEMENTS

Under a license and distribution agreement with Cangene Corporation (“Cangene”), we have exclusive rights to distribute and market WinRho SDF in the U.S. Cangene, which holds the FDA licenses for the product, is required to supply the necessary quantities of WinRho SDF to support such sales and shares equally in the profits from sales after accounting for the costs of production and selling expenses. We report Cangene’s share of profits as royalty expense. The license and distribution agreement concludes in March 2005.

In 1997, we acquired from Baxter the exclusive rights to Autoplex T in the U.S., Canada and Mexico. In connection with the acquisition, Baxter agreed to manufacture Autoplex T for us until May 2000 or such later time as may be determined under the terms of a consent order entered into between Baxter and the Federal Trade Commission (“FTC”), but in any event four months after we receive approval from the FDA to manufacture Autoplex T. At the discretion of the FTC, the period Baxter manufactures Autoplex T can be extended for up to four twelve-month intervals. The FTC approved the third twelve-month extension beginning in May 2002. The FTC could require us to return our rights to Autoplex T to Baxter if we do not obtain FDA approval to manufacture the product by May 2003 or by a later date agreed to by the FTC. We anticipate that the period Baxter manufactures Autoplex T under the terms of the consent order from the FTC will be extended for the twelve-month period through May 2004. If the rights revert to Baxter and Baxter later sells these rights, we would share equally the proceeds of any such sale with Baxter, and under certain circumstances Baxter will be required to make a specified payment to us. Upon FDA licensure to manufacture the product, we are obligated to pay $1.0 million to Baxter, subject to recovery of fifty percent (50%) of expenditures incurred to license the product in excess of $6.0 million.

In 1999, we entered into a five-year agreement with DSM Pharmaceuticals, Inc. (formerly Catalytica Pharmaceuticals) (“DSM”) for exclusive distribution rights in the U.S. and Canada for Aloprim. Under this agreement, we sell and DSM manufactures the product and both companies share equally in profits from the sale of the product after accounting for the costs of production and selling expenses on the first $4 million of product sales in any given year. On sales of Aloprim in excess of $4 million in a year, profits are shared 70% to us and 30% to DSM. In the event DSM obtains sales and distribution rights in additional territories to the U.S. and Canada, we can purchase the rights to Aloprim in these additional territories. We have the option to acquire the rights to manufacture and distribute the product from DSM prior to expiration of the distribution agreement. Our current agreement with DSM expires in 2004.

In May 2000, we entered into agreements with Dow for the contract production and commercial supply of StaphVAX. The manufacturing process for StaphVAX is being transferred to Dow from our pilot manufacturing plant in Rockville, Maryland. We plan to use StaphVAX material from initial clinical lots manufactured at Dow under cGMP for an immunogenicity study and for the confirmatory Phase III trial planned to commence in 2003. We expect Dow to complete scale-up of manufacturing at the facility and to begin the production of consistency lots of StaphVAX in 2004. The contract manufacturing agreements required us to make certain payments to Dow to secure future access to commercial vaccine manufacturing capacity and to enable Dow to ready its facility for the future commercial scale manufacture of StaphVAX, its intended use. These payments have been recorded as a Manufacturing Right and included in Intangible Assets. Amortization of the Manufacturing Right is expected to commence when commercial manufacture of StaphVAX commences at Dow. The contract to ready the Dow facility to manufacture StaphVAX was originally scheduled to expire in October 2002, has been extended to March 2003. We expect to execute amended contracts with Dow to complete readying the facility for its intended use and for the commercial manufacture of StaphVAX in March 2003. These contracts are

expected to require us to make significant additional payments to Dow which will also be recorded as a Manufacturing Right to ready its facility for the commercial manufacture of StaphVAX.

NOTE 18 COMMITMENTS AND CONTINGENCIES

In February 2003, we entered into an agreement to construct a facility in Boca Raton, Florida to house our laboratory facility and cold storage capacity that is expected to replace our leased facilities in Miami, Florida. This agreement includes a noncancelable capital commitment of approximately $3.2 million.

As of December 28, 2002, we had open purchase order commitments of $5.7 million. See lease commitments discussed at Note 15.

We are a party to litigation in the ordinary course of business. We do not believe that any such litigation will have a material adverse effect on our business, financial position or results of operations.

During 2002, we were named as one of over 40 pharmaceutical and biopharmaceutical defendants in three class action lawsuits, filed in the Superior Court of the State of California; two filed in the County of San Francisco on August 23, 2002 and September 9, 2002 and one filed in the County of Alameda on July 12, 2002. The cases each involve claims that insurers and consumers of defendants’ products made overpayments for those products based on an alleged manipulation of Average Wholesale Price (“AWP”), a standard which governs amounts that physicians, hospitals and other providers receive as reimbursement for purchases of defendants’ products. The plaintiffs seek damages, equitable relief and disgorgement of profits. The three lawsuits are in their preliminary stages; no class has been certified. To date, we have been served in only one of the three suits. The lawsuits do not allege that we collected monies from the putative plaintiffs. We believe that, to the extent the putative plaintiffs made any payments based on AWP, such payments were made to physicians, hospitals and other providers, not to us. We deny any liability and intend to vigorously defend the suits.

NOTE 19 INDUSTRY SEGMENT INFORMATION

We manage our operations in two reportable segments, the biopharmaceutical products and antibody products segments. The biopharmaceutical products segment consists of the production and sale of proprietary biopharmaceutical products and research and development efforts for the biopharmaceutical product lines. The antibody products segment consists of the collection and sale of non-specific and specialty antibody products to other biopharmaceutical manufacturers, the production and sale of antibody-based control and diagnostic products and laboratory testing services.

The accounting policies for each of the segments are the same as those described in the summary of significant accounting policies. There are no inter-segment sales. Antibody product used to manufacture Nabi-HB is transferred from our antibody segment to our biopharmaceutical segment at cost. We evaluate the performance of each segment based on operating profit or loss. There is no inter-segment allocation of interest expense and income taxes.

Earnings per share were calculated for each three-month and twelve-month period on a stand-alone basis. The sum of the earnings per share for four quarters may not equal the earnings per share for the twelve months.

The results for the first quarter of 2002 included lower sales of biopharmaceutical products compared to the remainder of the quarters in 2002, due to seasonal fluctuations in our normal sales patterns. Operating expenses, particularly research and development expenses, did not vary in accordance with sales activity resulting in the quarterly net loss.

The results for the third quarter of 2001 included the gain on the sale of the majority of the antibody collection business and testing laboratory assets.

The results for the fourth quarter of 2001 included the benefit of the settlement of an arbitration proceeding with Baxter and the impact of changes in the estimated carrying values of deferred tax asset and liability balances at December 29, 2001.

NABI BIOPHARMACEUTICALS - -------------------------------------------------------------------------------- EXHIBIT 4.4 AGREEMENT OF SUBSTITUTION AND AMENDMENT OF RIGHTS AGREEMENT This Agreement of Substitution and Amendment is entered into as of July 1, 2002, by and among Nabi Biopharmaceuticals, a Delaware corporation (the "Company"), Registrar and Transfer Company (the "Old Agent") and American Stock Transfer & Trust Company, a New York banking corporation (the "New Agent"). RECITALS A. On or about August 1, 1997, the Company entered into a Rights Agreement, as subsequently amended (the "Rights Agreement"), with the Old Agent as rights agent. B. The Company wishes to amend the Rights Agreement in accordance with Section 27 thereof. C. The Company wishes to remove the Old Agent and substitute the New Agent as rights agent pursuant to Section 21 of the Rights Agreement. D. The Company has given the Old Agent proper notice of removal of the Old Agent as rights agent. AGREEMENT NOW THEREFORE, in consideration of the foregoing and of other consideration, the receipt and sufficiency of which is hereby acknowledged, the parties agree as follows: 1. In accordance with Section 27 of the Rights Agreement, the Company hereby amends the Rights Agreement by deleting the second sentence of Section 21 in its entirety and inserting the following in lieu thereof: "The Company may remove the Rights Agent or any successor Rights Agent upon 30 days' notice in writing, mailed to the Rights Agent or any successor Rights Agent, as the case may be, and to each transfer agent of the Common Shares or Series One Preferred Shares by registered or certified mail." 2. In accordance with Section 27 of the Rights Agreement, the Company hereby amends the Rights Agreement by deleting the fifth sentence of Section 21 in its entirety and inserting the following in lieu thereof:

"Any successor Rights Agent, whether appointed by the Company or by such a court, shall be (i) a corporation organized and doing business under the laws of the United States or of the State of Florida (or of any other state of the United States), in good standing, which is authorized under such laws to exercise corporate trust or stock transfer powers and is subject to supervision or examination by federal or state authority and which has at the time of its appointment as Rights Agent a combined capital and surplus of at least $10 million or (ii) an Affiliate of a corporation described in clause (i) of this sentence." 3. The Company hereby removes the Old Agent as rights agent pursuant to Section 21 of the Rights Agreement. 4. The Old Agent hereby acknowledges that the Company has given the Old Agent proper notice of removal of the Old Agent as rights agent. 5. The Company hereby appoints the New Agent as rights agent pursuant to Section 21 of the Rights Agreement, to serve in that capacity for the consideration and subject to all of the terms and conditions of the Rights Agreement. 6. The New Agent hereby accepts the appointment as rights agent pursuant to Section 21 of the Rights Agreement and agrees to serve in that capacity for the consideration and subject to all of the terms and conditions of the Rights Agreement. 7. From and after the effective date hereof, each and every reference in the Rights Agreement to a "Rights Agent" shall be deemed to be a reference to the New Agent. 8. In accordance with Section 27 of the Rights Agreement, the Company hereby amends the Rights Agreement by deleting the form of legend in Section 3(b) in its entirety and inserting the following in lieu thereof: "This certificate also evidences and entitles the holder hereof to certain Rights as set forth in a Rights Agreement between Nabi Biopharmaceuticals and American Stock Transfer & Trust Company, dated as of August 1, 1997, as amended (the "Rights Agreement"), the terms of which are hereby incorporated herein by reference and a copy of which is on file at the principal executive offices of Nabi Biopharmaceuticals. Under certain circumstances, as set forth in the Rights Agreement, such Rights will be evidenced by separate certificates and will no longer be evidenced by this certificate. Nabi Biopharmaceuticals will mail to the holder of this certificate a copy of the Rights Agreement without charge after receipt of a written request therefor. Under certain circumstances set forth in the Rights Agreement, Rights issued to, or held by, any Person who is, was or becomes an Acquiring Person or any Affiliate or Associate thereof (as such terms are defined in the Rights Agreement), whether currently held by or on behalf of such Person or by any subsequent holder, may become null and void. The Rights shall not be exercisable, and shall be void so long as held by a holder in any jurisdiction where the requisite qualification to the 2

issuance to such holder, or the exercise by such holder, of the Rights in such jurisdiction shall not have been obtained or be obtainable." 9. In accordance with Section 27 of the Rights Agreement, the Company hereby amends the Rights Agreement to provide that notices or demands pursuant to Section 26 shall be addressed as follows: If to the Company: Nabi Biopharmaceuticals 5800 Park of Commerce Boulevard, NW Boca Raton, FL 33487 Attention: Chief Financial Officer If to the Rights Agent: American Stock Transfer & Trust Company 59 Maiden Lane New York, NY 10038 Attention: Shareholder Services Division 10.

NABI BIOPHARMACEUTICALS - -------------------------------------------------------------------------------- EXHIBIT 10.31 NABI BIOPHARMACEUTICALS 5800 PARK OF COMMERCE BOULEVARD, N.W. BOCA RATON, FLORIDA 33487 EFFECTIVE AS OF 11/11/02 Daniel Greenleaf Basking Ridge, NJ 07920 Dear Dan: You have agreed to serve as Sr. Vice President, Operations for Nabi Biopharmaceuticals ("Nabi"). The following are the terms of such employment: 1. TERM: You will serve as a Sr. Vice President, Operations of Nabi for a period beginning as of the date hereof and ending on 10/31/2005, unless your employment is sooner terminated as provided below (the "Employment Period"). In the event that your employment by the Company continues beyond the Employment Period, your continued employment by the Company shall be on an at will basis and may be terminated by either party upon thirty (30) days' prior notice unless you and the Company shall have entered into a written renewal of this Agreement. 2. SALARY: Your salary will be $235,000 per year, payable bi-weekly during the Employment Period. Your salary will be subject to discretionary annual increases as determined by Nabi's Board of Directors. 3. BONUS: You will be entitled to participate in Nabi's VIP Management Incentive Program. Unless the Employment Period is terminated for "cause" pursuant to Section 7(B)(b) below, bonus compensation shall be pro rated in respect of any calendar year during which the Employment Period terminates based on the amount of bonus compensation which would have been payable with respect to such year per your original VIP Management Incentive Program participation, divided by 12, times the number of full calendar months during the relevant year you were employed prior to the termination of the Employment Period. If the Employment Period is terminated pursuant to Section 7 (B)(b) below, no bonus compensation is payable with respect to the calendar year during which it is terminated. Bonus payments shall be payable within 120 days after the end of the relevant calendar year. 4. AUTO ALLOWANCE: While an employee under the terms of this Agreement, you shall receive an auto allowance of not less than $900.00 per month.

5. BENEFITS: During the Employment Period, you will be eligible to participate in such fringe benefits programs as are accorded to other similarly situated Nabi employees. 6. DUTIES AND EXTENT OF SERVICES: (A) During the Employment Period, you agree to devote substantially all of your working time, and such energy, knowledge, and efforts as is necessary to the discharge and performance of your duties provided for in this Agreement and such other reasonable duties and responsibilities consistent with your position as are assigned to you from time to time by the person to whom you report. You shall be located primarily in Nabi's Boca Raton, Florida facilities, but shall travel to other locations from time to time as shall be reasonably required in the course of performance of your duties. (B) During the Employment Period, you shall serve as a Sr. Vice President, Operations with "Operations" being defined as Manufacturing, Sales and Marketing. You shall have such duties as are delegated to you by the person to whom you report provided that such duties shall be reasonably consistent with those duties assigned to executive officers having similar titles in organizations comparable to Nabi. 7. TERMINATION: (A) The Employment Period shall terminate upon your death. You may also terminate the Employment Period upon thirty (30) days' prior written notice to Nabi. Any termination pursuant to this Section 7(A) shall not affect any bonus compensation applicable to the year of such termination, provided that any bonus compensation payable pursuant to Section 3 of this Agreement shall be pro rated as provided for in Section 3. (B) Nabi may terminate the Employment Period in the event of (a) your inability to perform the essential functions of your position, with or without reasonable accommodation for any three (3) consecutive months as the result of mental or physical incapacity (Nabi shall determine in good faith whether you are unable to perform the essential functions of your position). This determination of disability shall be made by a physician satisfactory to both you and Nabi, provided that if you and Nabi do not agree on a physician, you and Nabi shall each select a physician and these two together shall select a third physician, whose determination as to disability shall be binding on all parties. or (b) for "cause", which is defined as (i) commission of fraud or embezzlement or other felonious acts by you, (ii) your refusal to comply with reasonable directions in connection with the performance of your duties as provided for in Section 6 of this Agreement after written notice of such failure is delivered to you, (iii) failure to comply with the provisions of Section 9 or 10 of this Agreement or (iv) your gross negligence in connection with the performance of your duties as provided for in this Agreement, which gross negligence causes material damage to Nabi, provided that, in the event of termination under this clause (b), you shall receive ten (10) days' written notice prior to termination and a determination must be made 2

by Nabi's Board of Directors or a duly appointed committee of the Board, after you are afforded an opportunity to be heard, that it is, at the date of such termination, reasonable to conclude that grounds for such termination under this clause (b) still exists. (C) Nabi may otherwise terminate the Employment Period upon thirty (30) days' prior notice to you. (D) Your confidentiality and non-competition agreements set forth in Sections 9 and 10 below shall survive the termination of your employment regardless of the reasons therefor. 8. SEVERANCE (A) In the event that (a) your employment terminates pursuant to Section 7C or (b) within thirty (30) days after the expiration of the Employment Period, either you give notice of termination of employment to the Company or the Company gives you notice of termination of employment other than for cause (as defined above) or disability, and provided that within thirty (30) days prior to the expiration of the Employment Period Nabi had not offered to renew this Agreement on terms no less favorable to you than the terms then in effect, you shall receive the benefits set forth in Section 8B, 8C and 8D. In the event your employment terminates pursuant to Section 7B (a), or as a result of your death, the benefit set forth in Section 8D shall be initiated. (B) Based on the effective date of such termination, Nabi will pay you severance pay of twelve (12) months of your annual base salary as in effect at the time of such termination ("Severance Pay") and maintain in effect for a twelve (12) month period such fringe benefits as are accorded to other similarly situated employees (to the extent allowed under, and subject to the limitations of, applicable plans). Severance Pay provided for in this paragraph shall be made in twenty-six (26) equal bi-weekly installments. (C) The Company shall pay up to $25,000 for outplacement services provided to you by an organization selected by you. (D) All non-vested stock options, restricted stock or similar incentive equity instruments pursuant to the Company's 2000 Employee Non-Qualified Stock Option Plan and/or successor plans (the "Options") shall immediately vest. All such "Options" shall be exercisable for one (1) year past termination date, except that no "Options" shall be exercisable beyond the original "Option" expiration date. To the extent the terms of any "Options" are inconsistent with this Agreement, the terms of this Agreement shall control. (E) All payments or benefits to you under this Section 8 (other than payments or benefits already accrued and otherwise due under Nabi's employee benefit plans or programs, or as a result of your death) will not be given unless you execute (and do not rescind) a written employment termination agreement in a form prescribed by Nabi, which includes a general release of all claims against Nabi and related parties with respect to all matters occurring prior to or on the date of the release, including (but not limited to) employment matters or matters in connection with your termination. 3

9. CONFIDENTIALITY: You acknowledge that your duties as described in Section 6 of this Agreement will give you access to trade secrets and other confidential information of Nabi and/or its affiliates, including but not limited to information concerning production and marketing of their respective products, customer lists, and other information relating to their present or future operations (all of the foregoing, whether or not it qualifies as a "trade secret" under applicable law, is collectively called "Confidential Information"). You recognize that Confidential Information is proprietary to each such entity and gives each of them significant competitive advantage. Accordingly, you shall not use or disclose any of the Confidential Information during or after the Employment Period, except for the sole and exclusive benefit of the relevant company. Upon any termination of the Employment Period, you will return to the relevant company's office all documents, computer electronic information and files, e.g., diskettes, floppies etc. and other tangible embodiments of any Confidential Information. You agree that Nabi may be irreparably injured by any actual breach of your confidentiality agreement, that such injury may not be adequately compensable by monetary damages, and that, accordingly, the offended company may specifically enforce the provisions of this Section by application for injunction or similar remedy by any court of competent jurisdiction without affecting any claim for damages. 10. NON-COMPETITION: (A) You acknowledge that your services to be rendered are of a special and unusual character and have a unique value to Nabi the loss of which cannot adequately be compensated by damages in an action at law. In view of the unique value of the services, and because of the Confidential Information to be obtained by or disclosed to you, and as a material inducement to Nabi to enter into this Agreement and to pay to you the compensation referred to above and other consideration provided, you covenant and agree that you will not, during the term of your employment by Nabi and for a period of one (1) year after termination of such employment for any reason whatsoever, you will not, directly or indirectly, (a) engage or become interested, as owner, employee, consultant, partner, through stock ownership (except ownership of less than five percent of any class of securities which are publicly traded), investment of capital, lending of money or property, rendering of services, or otherwise, either alone or in association with others, in the operations, management or supervision of any type of business or enterprise engaged in any business which is competitive with any business of Nabi (a "Competitive Business"), (b) solicit or accept orders from any current or past customer of Nabi for products or services offered or sold by, or competitive with products or services offered or sold by, Nabi, (c) induce or attempt to induce any such customer to reduce such customer's purchase of products or services from Nabi, (d) disclose or use for the benefit of any Competitive Business the name and/or requirements of any such customer or (e) solicit any of Nabi's employees to leave the employ of Nabi or hire or negotiate for the employment of any employee of Nabi. At the time any of the provisions of Section 8 ("Severance") would be implemented, Nabi will determine in good faith, and in writing to you, the specific organizations that it defines as a "Competitive Business." 4

(B) You have carefully read and considered the provisions of this Section and Section 9 and having done so, agree that the restrictions set forth (including but not limited to the time period of restriction and the world wide areas of restriction) are fair and reasonable (even if termination is at our request and without cause) and are reasonably required for the protection of the interest of Nabi, its officers, directors, and other employees. You acknowledge that upon termination of this Agreement for any reason, it may be necessary for you to relocate to another area, and you agree that this restriction is fair and reasonable and is reasonably required for the protection of the interests of Nabi, their officers, directors, and other employees. (C) In the event that, notwithstanding the foregoing, any of the provisions of this Section or Section 9 shall be held to be invalid or unenforceable, the remaining provisions thereof shall nevertheless continue to be valid and enforceable as though invalid or unenforceable parts had not been included therein. In the event that any provision of this Section relating to time period and/or areas of restriction shall be declared by a court of competent jurisdiction to exceed the maximum time period or areas such court deems reasonable and enforceable, said time period and/or areas of restriction shall be deemed to become, and thereafter be, the maximum time period and/or area which such court deems reasonable and enforceable. (D) With respect to the provisions of this Section, you agree that damages, by themselves, may be an inadequate remedy at law, that an actual material breach of the provisions of this Section may cause irreparable injury to the aggrieved party, and that provisions of this Section 10 may be specifically enforced by application for injunction or similar remedy in any court of competent jurisdiction without affecting any claim for damages. 11. MISCELLANEOUS: This Agreement and the rights and obligations of the parties pursuant to it and any other instruments or documents issued pursuant to it shall be construed, interpreted and enforced in accordance with the laws of the State of Florida, exclusive of its choice-of-law principles. This Agreement shall be binding upon and inure to the benefit of the parties hereto, and their respective successors and assigns. The provisions of this Agreement shall be severable and the illegality, unenforceability or invalidity of any provision of this Agreement shall not affect or impair the remaining provisions hereof, and each provision of this Agreement shall be construed to be valid and enforceable to the full extent permitted by law. To the extent any provision of this Agreement is deemed to be illegal, unenforceable or invalid, the parties shall in good faith agree upon an alternative provision that effects, to the maximum extent practicable, the intent of the illegal, unenforceable or invalid provision. In any suit, action or proceeding arising out of or in connection with this Agreement, the prevailing party shall be entitled to receive an award of the reasonable related amount of attorneys' fees and disbursements incurred by such party, including fees and disbursements on appeal. This Agreement, along with your offer letter of employment and the Change of Control Agreement, is a complete expression of all agreements of the parties relating to the subject matter hereof, and all prior or contemporaneous oral or written understandings or agreements shall be null and void except to the extent set forth in this Agreement, your offer letter of employment and the Change of Control Agreement. 5

This Agreement cannot be amended orally, or by any course of conduct or dealing, but only by a written agreement signed by the party to be charged therewith. All notices required and allowed hereunder shall be in writing, and shall be deemed given upon deposit in the Certified Mail, Return Receipt Requested, first-class postage and registration fees prepaid, and correctly addressed to the party for whom intended at its address set forth under its name below, or to such other address as has been most recently specified by a party by one or more counterparts, each of which shall constitute one and the same agreement. All references to genders or number in this Agreement shall be deemed interchangeably to have a masculine, feminine, neuter, singular or plural meaning, as the sense of the context required. If the foregoing confirms your understanding of our agreements, please so indicate by signing in the space provided below and returning a signed copy to us.

NABI BIOPHARMACEUTICALS - -------------------------------------------------------------------------------- EXHIBIT 10.32 INDEMNIFICATION AGREEMENT This Indemnification Agreement is made and entered into this 11 day of September, 2000, between Nabi (the "Company") and Mark Smith (the "Indemnitee"), and is effective retroactively to the date of hire of the Indemnitee by Company. PRELIMINARY STATEMENT The board of directors of the Company has determined that highly competent persons will be difficult to retain unless they are adequately protected against liabilities incurred in performance of their services on behalf of the Company, and the Company's By-laws authorize the Company to enter into and perform Indemnification Agreements for this purpose. Therefore, the board of directors has determined that it is in the best interests of the Company to attract and retain persons such as the Indemnitee by providing adequate protection against such liabilities by means of Indemnification Agreements with persons such as the Indemnitee. NOW, THEREFORE, in consideration of the promises and covenants contained herein and as an inducement to the Indemnitee to continue as an employee of the Company, the Company and the Indemnitee, intending to be legally bound, do hereby agree as follows: 1. The Indemnitee agrees to serve as an employee of the Company until the Indemnitee's resignation by written notice to the Company or the Indemnitee's removal, whichever occurs earliest. 2. The Company agrees to indemnify and hold harmless the Indemnitee, with respect to any action taken or omitted by the Indemnitee while serving as an employee of the Company, to the fullest extent permissible under applicable law, as such law may be amended or supplemented from time to time. The Indemnitee's indemnification rights shall include but not be limited to the rights contained in the following paragraphs, except to the extent expressly prohibited by applicable law. 3. The Company shall indemnify and hold harmless the Indemnitee from and against expenses (including attorneys' fees and disbursements), judgments, damages, fines (including any excise taxes assessed on a person with respect to an employee benefit plan) and amounts paid in settlement actually and reasonably incurred by the Indemnitee in connection with any threatened, pending or contemplated action, suit or proceeding, or appeal thereof, whether civil, criminal or administrative, or in connection with any internal or external investigation (other than an action by or in the right of the Company) if the Indemnitee was or is a "party" (as used in this Agreement, "party" shall include the giving of testimony or similar involvement) or threatened to be made a party to such action, suit or proceeding by reason of the fact that the Indemnitee is or was a director, officer, employee or agent of the Company, or is or was serving at the request

of the Company as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise (including employee benefit plans); provided, however, that the Indemnitee shall be entitled to such indemnification only if the Indemnitee acted in good faith and in a manner the Indemnitee reasonably believed to be in or not opposed to the best interests of the Company, and, with respect to any criminal action or proceeding, the Indemnitee had no reasonable cause to believe such conduct was unlawful. The term "serving at the request of the Company" shall include any service as a director, officer, employee or agent of the Company which imposes duties on, or involves services by, such director, officer, employee or agent with respect to an employee benefit plan, its participants, or beneficiaries. A person who acted in good faith and in a manner he reasonably believed to be in the interest of the participants and beneficiaries of an employee benefit plan shall be deemed to have acted in a manner "not opposed to the best interests of the Company." 4. The Company shall indemnify and hold harmless the Indemnitee from and against expenses (including attorneys' fees and disbursements), and amounts paid in settlement, actually and reasonably incurred by the Indemnitee in connection with the defense or settlement of any threatened, pending or completed action or suit, or appeal thereof, by or in the right of the Company to procure a judgment in its favor if the Indemnitee was or is a party or threatened to be a party to such action or suit by reason of the fact that the Indemnitee is or was a director, officer, employee or agent of the Company, or is or was serving at the request of the Company as a director, officer, employer or agent of another corporation, partnership, joint venture, trust or other enterprise; provided, however, that the Indemnitee shall be entitled to such indemnification only if the Indemnitee acted in good faith and in a manner reasonably believed by the Indemnitee to be in or not opposed to the best interests of the Company and except that no indemnification shall be made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable in the performance of such person's duty to the Company if and to the extent that the court in which such action or suit was brought shall determine that the Indemnitee is not entitled to such indemnification. 5. The Company currently has in force policies of Directors and Officers Liability Insurance (the "D&O Policy"). The Company shall not be liable under this Indemnification Agreement for any amount of any claim for which the Indemnitee has been paid under the D&O Policy or under any other valid insurance policies maintained in the future by the Company for Indemnitee's benefit. The Company shall not be required to maintain the D&O Policy presently in effect or to replace such policy if, in the judgment of the board of directors of the Company, the cost of such policy is not reasonable in relation to the coverage provided. If the Company so decides not to maintain the current D&O Policy or replace it with policies with similar coverage, the Company agrees, in addition to and not in limitation of the indemnification otherwise provided for by this Indemnification Agreement, to indemnify and hold harmless the Indemnitee to the extent of coverage which would have been provided by the D&O Policy to the fullest extent permissible under applicable law. 6. Expenses incurred by the Indemnitee in connection with any action, suit, proceeding, or appeal thereof, described in Paragraphs 3 and 4 above, shall be paid by the Company in advance of the final disposition of such action, suit or proceeding within twenty (20) days of receipt of an undertaking by the Indemnitee to repay such amount if 2

it is ultimately determined by the board of directors, Independent Counsel (as defined below), the shareholders or a court, as provided in Paragraph 9 of this Indemnification Agreement, that the Indemnitee is not entitled to be indemnified by the Company or not entitled to full indemnification by the Company. 7. The Indemnitee's right to indemnification and advancement of expenses as set forth in this Indemnification Agreement shall not be exclusive of other rights the Indemnitee may have under applicable law, other agreements between the Company and the Indemnitee, the Certificate of Incorporation or By-laws of the Company, by vote of disinterested directors of the Company or by vote of the shareholders of the Company. 8. The indemnification and advancement of expenses provided by, or granted pursuant to, this Indemnification Agreement shall continue after the Indemnitee has ceased to be an employee of the Company and shall inure to the benefit of the heirs, executors and administrators of the Indemnitee. 9. Upon written request by the Indemnitee for indemnification under Paragraphs 3 and 4 above, a determination regarding the Indemnitee's entitlement to such indemnification shall be made by (1) the board of directors of the Company by a majority vote of a quorum consisting of directors who are not parties to the action, suit, settlement or proceeding, or (2) if such a quorum is not obtainable, or, even if obtainable, a quorum consisting of disinterested directors so directs, by Independent Counsel, as defined below, in a written opinion, or (3) by the shareholders of the Company. "Independent Counsel" shall mean a law firm or member of a law firm that has not within the last five (5) years represented the Company or the Indemnitee in a matter material to either or in a matter material to any other party to the action, suit or proceeding giving rise to the Indemnitee's claim for indemnification under this Indemnification Agreement. Independent Counsel shall not include any member of a law firm who would have a conflict of interest under applicable standards of professional conduct in representing the Company or the Indemnitee in an action hereunder. Such Independent Counsel shall be chosen by the board of directors of the Company and approved by the Indemnitee. Upon failure of the board of directors to choose, or the Indemnitee to approve, Independent Counsel, Independent Counsel shall be selected by the Chancellor of the State of Delaware or by an appointee of the Chancellor. Determination of entitled to indemnification shall be made within thirty (30) days of receipt by the Company of a written request for indemnification by the Indemnitee. The Indemnitee's request to the Company shall be accompanied by any documentation reasonably available to the Indemnitee relating to the Indemnitee's entitlement to be indemnified. All reasonable expenses (including attorneys' fees and disbursements) relating to the Indemnitee's request for indemnification under this Indemnification Agreement shall be paid by the Company regardless of the outcome of the determination as to the Indemnitee's entitlement to indemnification. If such determination is unfavorable to the Indemnitee or if the Indemnitee has made no request for indemnification hereunder or no determination is otherwise made, the Indemnitee may within two (2) years after such determination, or, if no determination has been made, within two (2) years after the Indemnitee has incurred the expense or otherwise made a payment for which the Indemnitee seeks indemnification, petition the Court of Chancery of the State of Delaware or any other court of competent jurisdiction to determine whether the Indemnitee is entitled to indemnification under 3

the terms of this Indemnification Agreement or otherwise. The Indemnitee shall not be prejudiced in such judicial proceeding by a prior determination that the Indemnitee is not entitled to indemnification. The Company shall be precluded from asserting in such judicial proceeding that it is not bound by the provisions of this Indemnification Agreement. The Company shall pay all expenses (including attorneys' fees and disbursements incurred or at trial or on one or more appeals) actually and reasonably incurred by the Indemnitee in connection with such judicial determination. 10. If any action, suit or proceeding described in Paragraphs 3 and 4 above shall be terminated by judgment, order, settlement or conviction or upon a plea of NOLO CONTENDERE or its equivalent, no presumption shall be created that the Indemnitee did not act in good faith and in a manner which he reasonably believed to be in or not opposed to the best interests of the Company, and, with respect to any criminal action or proceeding, that the Indemnitee had reasonable cause to believe that his conduct was unlawful. 11. In each request made by Indemnitee for indemnity or advancement of expenses under this Indemnification Agreement, the Indemnitee shall be presumed to have satisfied the required standard of conduct and any and all other conditions precedent to such indemnity and/or advancement, unless and until the contrary is established. 12. Notwithstanding any other provision of the Indemnification Agreement, the Company shall not be liable to indemnify the Indemnitee under this Indemnification Agreement in connection with any claim against Indemnitee: (a) for which the Indemnitee is indemnified by the Company other than under this Indemnification Agreement; (b) if a court of competent jurisdiction has rendered a final decision that indemnification relating to the claim would be unlawful; (c) if pursuant to Section 16(b) of the Securities Exchange Act of 1934, as amended, or similar provisions of any state or federal statutory law, the claim is for an accounting of profits made from the purchase and sale by the Indemnitee of securities of the Company; (d) if a final decision by a court of competent jurisdiction shall adjudge the Indemnitee's conduct to have been knowingly fraudulent or deliberately dishonest and to be material to the claim adjudicated by the court; or (e) if the claim was based upon the Indemnitee's deriving an unlawful personal benefit and a court of competent jurisdiction adjudges that such benefit was unlawful in a final decision. 13. If any provision of this Indemnification Agreement or the application thereof to any particular facts or circumstances shall be held to be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions (including portions of any paragraph of this Indemnification Agreement containing an invalid, illegal or unenforceable provision) and the application thereof to facts or circumstances other than those as to which it is held invalid, illegal, or unenforceable shall not be impaired or affected thereby. This Indemnification Agreement shall be construed to be valid and enforceable to the full extent allowed by law, and any invalid, illegal 4

or unenforceable provision of this Indemnification Agreement shall be modified as necessary to comply with all applicable laws. 14. This Indemnification Agreement may be executed in one or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument. 15. This Indemnification Agreement shall be governed by, and construed in accordance with, the laws of the State of Delaware applicable to contracts made and wholly performed in such state. 16. All notices or other communication hereunder shall be in writing and shall be deemed to be effective and to have been duly given if delivered by certified mail postage prepaid, return receipt requested, to the respective parties, as follows: If to the Company: Nabi 5800 Park of Commerce Boulevard, N.W. Boca Raton, FL 33487 Attention: President & CEO If to Indemnitee: Mark Smith Boca Raton, FL 33428 or to such other address as a party may have furnished to the other in writing in accordance with this paragraph, except that notices of change of address shall only be effective upon receipt. 17. This Indemnification Agreement shall be binding upon the Company and its successors and assigns and shall inure to the benefit of (and be enforceable against the Company by) the Indemnitee and the Indemnitee's heirs, executors and administrators. 18. No amendment of this Indemnification Agreement shall be binding unless executed in writing by both parties hereto. No waiver of any provision of this Indemnification Agreement shall constitute a waiver of any other provision hereof. 19. The Indemnitee shall notify the Company in writing within thirty days after being served with any summons, citation, subpoena, complaint, indictment, information or other document relating to any matter concerning which the Indemnitee may be entitled to indemnification hereunder, but the failure to give such notice shall not affect the Company's obligation to indemnify the Indemnitee to the extent provided for herein or otherwise. 5

NABI BIOPHARMACEUTICALS - -------------------------------------------------------------------------------- EXHIBIT 10.33 INDEMNIFICATION AGREEMENT This Indemnification Agreement is made and entered into this 11th day of September, 2000, between Nabi (the "Company") and Thomas H. McLain (the "Indemnitee"), and is effective retroactively to the date of hire of the Indemnitee by Company. PRELIMINARY STATEMENT The board of directors of the Company has determined that highly competent persons will be difficult to retain unless they are adequately protected against liabilities incurred in performance of their services on behalf of the Company, and the Company's By-laws authorize the Company to enter into and perform Indemnification Agreements for this purpose. Therefore, the board of directors has determined that it is in the best interests of the Company to attract and retain persons such as the Indemnitee by providing adequate protection against such liabilities by means of Indemnification Agreements with persons such as the Indemnitee. NOW, THEREFORE, in consideration of the promises and covenants contained herein and as an inducement to the Indemnitee to continue as an employee of the Company, the Company and the Indemnitee, intending to be legally bound, do hereby agree as follows: 1. The Indemnitee agrees to serve as an employee of the Company until the Indemnitee's resignation by written notice to the Company or the Indemnitee's removal, whichever occurs earliest. 2. The Company agrees to indemnify and hold harmless the Indemnitee, with respect to any action taken or omitted by the Indemnitee while serving as an employee of the Company, to the fullest extent permissible under applicable law, as such law may be amended or supplemented from time to time. The Indemnitee's indemnification rights shall include but not be limited to the rights contained in the following paragraphs, except to the extent expressly prohibited by applicable law. 3. The Company shall indemnify and hold harmless the Indemnitee from and against expenses (including attorneys' fees and disbursements), judgments, damages, fines (including any excise taxes assessed on a person with respect to an employee benefit plan) and amounts paid in settlement actually and reasonably incurred by the Indemnitee in connection with any threatened, pending or contemplated action, suit or proceeding, or appeal thereof, whether civil, criminal or administrative, or in connection with any internal or external investigation (other than an action by or in the right of the Company) if the Indemnitee was or is a "party" (as used in this Agreement, "party" shall include the giving of testimony or similar involvement) or threatened to be made a party to such action, suit or proceeding by reason of the fact that the Indemnitee is or was a director, officer, employee or agent of the Company, or is or was serving at the request

of the Company as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise (including employee benefit plans); provided, however, that the Indemnitee shall be entitled to such indemnification only if the Indemnitee acted in good faith and in a manner the Indemnitee reasonably believed to be in or not opposed to the best interests of the Company, and, with respect to any criminal action or proceeding, the Indemnitee had no reasonable cause to believe such conduct was unlawful. The term "serving at the request of the Company" shall include any service as a director, officer, employee or agent of the Company which imposes duties on, or involves services by, such director, officer, employee or agent with respect to an employee benefit plan, its participants, or beneficiaries. A person who acted in good faith and in a manner he reasonably believed to be in the interest of the participants and beneficiaries of an employee benefit plan shall be deemed to have acted in a manner "not opposed to the best interests of the Company." 4. The Company shall indemnify and hold harmless the Indemnitee from and against expenses (including attorneys' fees and disbursements), and amounts paid in settlement, actually and reasonably incurred by the Indemnitee in connection with the defense or settlement of any threatened, pending or completed action or suit, or appeal thereof, by or in the right of the Company to procure a judgment in its favor if the Indemnitee was or is a party or threatened to be a party to such action or suit by reason of the fact that the Indemnitee is or was a director, officer, employee or agent of the Company, or is or was serving at the request of the Company as a director, officer, employer or agent of another corporation, partnership, joint venture, trust or other enterprise; provided, however, that the Indemnitee shall be entitled to such indemnification only if the Indemnitee acted in good faith and in a manner reasonably believed by the Indemnitee to be in or not opposed to the best interests of the Company and except that no indemnification shall be made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable in the performance of such person's duty to the Company if and to the extent that the court in which such action or suit was brought shall determine that the Indemnitee is not entitled to such indemnification. 5. The Company currently has in force policies of Directors and Officers Liability Insurance (the "D&O Policy"). The Company shall not be liable under this Indemnification Agreement for any amount of any claim for which the Indemnitee has been paid under the D&O Policy or under any other valid insurance policies maintained in the future by the Company for Indemnitee's benefit. The Company shall not be required to maintain the D&O Policy presently in effect or to replace such policy if, in the judgment of the board of directors of the Company, the cost of such policy is not reasonable in relation to the coverage provided. If the Company so decides not to maintain the current D&O Policy or replace it with policies with similar coverage, the Company agrees, in addition to and not in limitation of the indemnification otherwise provided for by this Indemnification Agreement, to indemnify and hold harmless the Indemnitee to the extent of coverage which would have been provided by the D&O Policy to the fullest extent permissible under applicable law. 6. Expenses incurred by the Indemnitee in connection with any action, suit, proceeding, or appeal thereof, described in Paragraphs 3 and 4 above, shall be paid by the Company in advance of the final disposition of such action, suit or proceeding within twenty (20) days of receipt of an undertaking by the Indemnitee to repay such amount if 2

it is ultimately determined by the board of directors, Independent Counsel (as defined below), the shareholders or a court, as provided in Paragraph 9 of this Indemnification Agreement, that the Indemnitee is not entitled to be indemnified by the Company or not entitled to full indemnification by the Company. 7. The Indemnitee's right to indemnification and advancement of expenses as set forth in this Indemnification Agreement shall not be exclusive of other rights the Indemnitee may have under applicable law, other agreements between the Company and the Indemnitee, the Certificate of Incorporation or By-laws of the Company, by vote of disinterested directors of the Company or by vote of the shareholders of the Company. 8. The indemnification and advancement of expenses provided by, or granted pursuant to, this Indemnification Agreement shall continue after the Indemnitee has ceased to be an employee of the Company and shall inure to the benefit of the heirs, executors and administrators of the Indemnitee. 9. Upon written request by the Indemnitee for indemnification under Paragraphs 3 and 4 above, a determination regarding the Indemnitee's entitlement to such indemnification shall be made by (1) the board of directors of the Company by a majority vote of a quorum consisting of directors who are not parties to the action, suit, settlement or proceeding, or (2) if such a quorum is not obtainable, or, even if obtainable, a quorum consisting of disinterested directors so directs, by Independent Counsel, as defined below, in a written opinion, or (3) by the shareholders of the Company. "Independent Counsel" shall mean a law firm or member of a law firm that has not within the last five (5) years represented the Company or the Indemnitee in a matter material to either or in a matter material to any other party to the action, suit or proceeding giving rise to the Indemnitee's claim for indemnification under this Indemnification Agreement. Independent Counsel shall not include any member of a law firm who would have a conflict of interest under applicable standards of professional conduct in representing the Company or the Indemnitee in an action hereunder. Such Independent Counsel shall be chosen by the board of directors of the Company and approved by the Indemnitee. Upon failure of the board of directors to choose, or the Indemnitee to approve, Independent Counsel, Independent Counsel shall be selected by the Chancellor of the State of Delaware or by an appointee of the Chancellor. Determination of entitled to indemnification shall be made within thirty (30) days of receipt by the Company of a written request for indemnification by the Indemnitee. The Indemnitee's request to the Company shall be accompanied by any documentation reasonably available to the Indemnitee relating to the Indemnitee's entitlement to be indemnified. All reasonable expenses (including attorneys' fees and disbursements) relating to the Indemnitee's request for indemnification under this Indemnification Agreement shall be paid by the Company regardless of the outcome of the determination as to the Indemnitee's entitlement to indemnification. If such determination is unfavorable to the Indemnitee or if the Indemnitee has made no request for indemnification hereunder or no determination is otherwise made, the Indemnitee may within two (2) years after such determination, or, if no determination has been made, within two (2) years after the Indemnitee has incurred the expense or otherwise made a payment for which the Indemnitee seeks indemnification, petition the Court of Chancery of the State of Delaware or any other court of competent jurisdiction to determine whether the Indemnitee is entitled to indemnification under 3

the terms of this Indemnification Agreement or otherwise. The Indemnitee shall not be prejudiced in such judicial proceeding by a prior determination that the Indemnitee is not entitled to indemnification. The Company shall be precluded from asserting in such judicial proceeding that it is not bound by the provisions of this Indemnification Agreement. The Company shall pay all expenses (including attorneys' fees and disbursements incurred or at trial or on one or more appeals) actually and reasonably incurred by the Indemnitee in connection with such judicial determination. 10. If any action, suit or proceeding described in Paragraphs 3 and 4 above shall be terminated by judgment, order, settlement or conviction or upon a plea of NOLO CONTENDERE or its equivalent, no presumption shall be created that the Indemnitee did not act in good faith and in a manner which he reasonably believed to be in or not opposed to the best interests of the Company, and, with respect to any criminal action or proceeding, that the Indemnitee had reasonable cause to believe that his conduct was unlawful. 11. In each request made by Indemnitee for indemnity or advancement of expenses under this Indemnification Agreement, the Indemnitee shall be presumed to have satisfied the required standard of conduct and any and all other conditions precedent to such indemnity and/or advancement, unless and until the contrary is established. 12. Notwithstanding any other provision of the Indemnification Agreement, the Company shall not be liable to indemnify the Indemnitee under this Indemnification Agreement in connection with any claim against Indemnitee: (a) for which the Indemnitee is indemnified by the Company other than under this Indemnification Agreement; (b) if a court of competent jurisdiction has rendered a final decision that indemnification relating to the claim would be unlawful; (c) if pursuant to Section 16(b) of the Securities Exchange Act of 1934, as amended, or similar provisions of any state or federal statutory law, the claim is for an accounting of profits made from the purchase and sale by the Indemnitee of securities of the Company; (d) if a final decision by a court of competent jurisdiction shall adjudge the Indemnitee's conduct to have been knowingly fraudulent or deliberately dishonest and to be material to the claim adjudicated by the court; or (e) if the claim was based upon the Indemnitee's deriving an unlawful personal benefit and a court of competent jurisdiction adjudges that such benefit was unlawful in a final decision. 13. If any provision of this Indemnification Agreement or the application thereof to any particular facts or circumstances shall be held to be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions (including portions of any paragraph of this Indemnification Agreement containing an invalid, illegal or unenforceable provision) and the application thereof to facts or circumstances other than those as to which it is held invalid, illegal, or unenforceable shall not be impaired or affected thereby. This Indemnification Agreement shall be construed to be valid and enforceable to the full extent allowed by law, and any invalid, illegal 4

or unenforceable provision of this Indemnification Agreement shall be modified as necessary to comply with all applicable laws. 14. This Indemnification Agreement may be executed in one or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument. 15.

NABI BIOPHARMACEUTICALS - -------------------------------------------------------------------------------- EXHIBIT 10.34 INDEMNIFICATION AGREEMENT This Indemnification Agreement is made and entered into this 25th day of November, 2002, between Nabi Biopharmaceuticals (the "Company") and Daniel Greenleaf (the "Indemnitee"), and is effective retroactively to the date of hire of the Indemnitee by Company. PRELIMINARY STATEMENT The board of directors of the Company has determined that highly competent persons will be difficult to retain unless they are adequately protected against liabilities incurred in performance of their services on behalf of the Company, and the Company's By-laws authorize the Company to enter into and perform Indemnification Agreements for this purpose. Therefore, the board of directors has determined that it is in the best interests of the Company to attract and retain persons such as the Indemnitee by providing adequate protection against such liabilities by means of Indemnification Agreements with persons such as the Indemnitee. NOW, THEREFORE, in consideration of the promises and covenants contained herein and as an inducement to the Indemnitee to continue as an employee of the Company, the Company and the Indemnitee, intending to be legally bound, do hereby agree as follows: 1. The Indemnitee agrees to serve as an employee of the Company until the Indemnitee's resignation by written notice to the Company or the Indemnitee's removal, whichever occurs earliest. 2. The Company agrees to indemnify and hold harmless the Indemnitee, with respect to any action taken or omitted by the Indemnitee while serving as an employee of the Company, to the fullest extent permissible under applicable law, as such law may be amended or supplemented from time to time. The Indemnitee's indemnification rights shall include but not be limited to the rights contained in the following paragraphs, except to the extent expressly prohibited by applicable law. 3. The Company shall indemnify and hold harmless the Indemnitee from and against expenses (including attorneys' fees and disbursements), judgments, damages, fines (including any excise taxes assessed on a person with respect to an employee benefit plan) and amounts paid in settlement actually and reasonably incurred by the Indemnitee in connection with any threatened, pending or contemplated action, suit or proceeding, or appeal thereof, whether civil, criminal or administrative, or in connection with any internal or external investigation (other than an action by or in the right of the Company) if the Indemnitee was or is a "party" (as used in this Agreement, "party" shall include the giving of testimony or similar involvement) or threatened to be made a party to such action, suit or proceeding by reason of the fact that the Indemnitee is or was a director, officer, employee or agent of the Company, or is or was serving at the request of the Company as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise (including employee benefit plans); provided, however, that the

Indemnitee shall be entitled to such indemnification only if the Indemnitee acted in good faith and in a manner the Indemnitee reasonably believed to be in or not opposed to the best interests of the Company, and, with respect to any criminal action or proceeding, the Indemnitee had no reasonable cause to believe such conduct was unlawful. The term "serving at the request of the Company" shall include any service as a director, officer, employee or agent of the Company which imposes duties on, or involves services by, such director, officer, employee or agent with respect to an employee benefit plan, its participants, or beneficiaries. A person who acted in good faith and in a manner he reasonably believed to be in the interest of the participants and beneficiaries of an employee benefit plan shall be deemed to have acted in a manner "not opposed to the best interests of the Company." 4. The Company shall indemnify and hold harmless the Indemnitee from and against expenses (including attorneys' fees and disbursements), and amounts paid in settlement, actually and reasonably incurred by the Indemnitee in connection with the defense or settlement of any threatened, pending or completed action or suit, or appeal thereof, by or in the right of the Company to procure a judgment in its favor if the Indemnitee was or is a party or threatened to be a party to such action or suit by reason of the fact that the Indemnitee is or was a director, officer, employee or agent of the Company, or is or was serving at the request of the Company as a director, officer, employer or agent of another corporation, partnership, joint venture, trust or other enterprise; provided, however, that the Indemnitee shall be entitled to such indemnification only if the Indemnitee acted in good faith and in a manner reasonably believed by the Indemnitee to be in or not opposed to the best interests of the Company and except that no indemnification shall be made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable in the performance of such person's duty to the Company if and to the extent that the court in which such action or suit was brought shall determine that the Indemnitee is not entitled to such indemnification. 5. The Company currently has in force policies of Directors and Officers Liability Insurance (the "D&O Policy"). The Company shall not be liable under this Indemnification Agreement for any amount of any claim for which the Indemnitee has been paid under the D&O Policy or under any other valid insurance policies maintained in the future by the Company for Indemnitee's benefit. The Company shall not be required to maintain the D&O Policy presently in effect or to replace such policy if, in the judgment of the board of directors of the Company, the cost of such policy is not reasonable in relation to the coverage provided. If the Company so decides not to maintain the current D&O Policy or replace it with policies with similar coverage, the Company agrees, in addition to and not in limitation of the indemnification otherwise provided for by this Indemnification Agreement, to indemnify and hold harmless the Indemnitee to the extent of coverage which would have been provided by the D&O Policy to the fullest extent permissible under applicable law. 6. Expenses incurred by the Indemnitee in connection with any action, suit, proceeding, or appeal thereof, described in Paragraphs 3 and 4 above, shall be paid by the Company in advance of the final disposition of such action, suit or proceeding within twenty (20) days of receipt of an undertaking by the Indemnitee to repay such amount if it is ultimately determined by the board of directors, Independent Counsel (as defined below), the shareholders or a court, as provided in Paragraph 9 of this Indemnification Agreement, that the Indemnitee is not entitled to be indemnified by the Company or not entitled to full indemnification by the Company. 7. The Indemnitee's right to indemnification and advancement of expenses as set forth in this Indemnification Agreement shall not be exclusive of other rights the Indemnitee may have under applicable law, 2

other agreements between the Company and the Indemnitee, the Certificate of Incorporation or By-laws of the Company, by vote of disinterested directors of the Company or by vote of the shareholders of the Company. 8. The indemnification and advancement of expenses provided by, or granted pursuant to, this Indemnification Agreement shall continue after the Indemnitee has ceased to be an employee of the Company and shall inure to the benefit of the heirs, executors and administrators of the Indemnitee. 9. Upon written request by the Indemnitee for indemnification under Paragraphs 3 and 4 above, a determination regarding the Indemnitee's entitlement to such indemnification shall be made by (1) the board of directors of the Company by a majority vote of a quorum consisting of directors who are not parties to the action, suit, settlement or proceeding, or (2) if such a quorum is not obtainable, or, even if obtainable, a quorum consisting of disinterested directors so directs, by Independent Counsel, as defined below, in a written opinion, or (3) by the shareholders of the Company. "Independent Counsel" shall mean a law firm or member of a law firm that has not within the last five (5) years represented the Company or the Indemnitee in a matter material to either or in a matter material to any other party to the action, suit or proceeding giving rise to the Indemnitee's claim for indemnification under this Indemnification Agreement. Independent Counsel shall not include any member of a law firm who would have a conflict of interest under applicable standards of professional conduct in representing the Company or the Indemnitee in an action hereunder. Such Independent Counsel shall be chosen by the board of directors of the Company and approved by the Indemnitee. Upon failure of the board of directors to choose, or the Indemnitee to approve, Independent Counsel, Independent Counsel shall be selected by the Chancellor of the State of Delaware or by an appointee of the Chancellor. Determination of entitlement to indemnification shall be made within thirty (30) days of receipt by the Company of a written request for indemnification by the Indemnitee. The Indemnitee's request to the Company shall be accompanied by any documentation reasonably available to the Indemnitee relating to the Indemnitee's entitlement to be indemnified. All reasonable expenses (including attorneys' fees and disbursements) relating to the Indemnitee's request for indemnification under this Indemnification Agreement shall be paid by the Company regardless of the outcome of the determination as to the Indemnitee's entitlement to indemnification. If such determination is unfavorable to the Indemnitee or if the Indemnitee has made no request for indemnification hereunder or no determination is otherwise made, the Indemnitee may within two (2) years after such determination, or, if no determination has been made, within two (2) years after the Indemnitee has incurred the expense or otherwise made a payment for which the Indemnitee seeks indemnification, petition the Court of Chancery of the State of Delaware or any other court of competent jurisdiction to determine whether the Indemnitee is entitled to indemnification under the terms of this Indemnification Agreement or otherwise. The Indemnitee shall not be prejudiced in such judicial proceeding by a prior determination that the Indemnitee is not entitled to indemnification. The Company shall be precluded from asserting in such judicial proceeding that it is not bound by the provisions of this Indemnification Agreement. The Company shall pay all expenses (including attorneys' fees and disbursements incurred or at trial or on one or more appeals) actually and reasonably incurred by the Indemnitee in connection with such judicial determination. 10. If any action, suit or proceeding described in Paragraphs 3 and 4 above shall be terminated by judgment, order, settlement or conviction or upon a plea of NOLO CONTENDERE or its equivalent, no presumption shall be created that the Indemnitee did not act in good faith and in a manner which he reasonably believed to be in or not opposed to the best interests of the Company, and, with respect to any 3

criminal action or proceeding, that the Indemnitee had reasonable cause to believe that his conduct was unlawful. 11. In each request made by Indemnitee for indemnity or advancement of expenses under this Indemnification Agreement, the Indemnitee shall be presumed to have satisfied the required standard of conduct and any and all other conditions precedent to such indemnity and/or advancement, unless and until the contrary is established. 12. Notwithstanding any other provision of the Indemnification Agreement, the Company shall not be liable to indemnify the Indemnitee under this Indemnification Agreement in connection with any claim against Indemnitee: (a) for which the Indemnitee is indemnified by the Company other than under this Indemnification Agreement; (b) if a court of competent jurisdiction has rendered a final decision that indemnification relating to the claim would be unlawful; (c) if pursuant to Section 16(b) of the Securities Exchange Act of 1934, as amended, or similar provisions of any state or federal statutory law, the claim is for an accounting of profits made from the purchase and sale by the Indemnitee of securities of the Company; (d) if a final decision by a court of competent jurisdiction shall adjudge the Indemnitee's conduct to have been knowingly fraudulent or deliberately dishonest and to be material to the claim adjudicated by the court; or (e) if the claim was based upon the Indemnitee's deriving an unlawful personal benefit and a court of competent jurisdiction adjudges that such benefit was unlawful in a final decision. 13. If any provision of this Indemnification Agreement or the application thereof to any particular facts or circumstances shall be held to be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions (including portions of any paragraph of this Indemnification Agreement containing an invalid, illegal or unenforceable provision) and the application thereof to facts or circumstances other than those as to which it is held invalid, illegal, or unenforceable shall not be impaired or affected thereby. This Indemnification Agreement shall be construed to be valid and enforceable to the full extent allowed by law, and any invalid, illegal or unenforceable provision of this Indemnification Agreement shall be modified as necessary to comply with all applicable laws. 14. This Indemnification Agreement may be executed in one or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument. 15. This Indemnification Agreement shall be governed by, and construed in accordance with, the laws of the State of Delaware applicable to contracts made and wholly performed in such state. 16. All notices or other communication hereunder shall be in writing and shall be deemed to be effective and to have been duly given if delivered by certified mail postage prepaid, return receipt requested, to the respective parties, as follows: 4

This Indemnification Agreement shall be binding upon the Company and its successors and assigns and shall inure to the benefit of (and be enforceable against the Company by) the Indemnitee and the Indemnitee's heirs, executors and administrators. 18. No amendment of this Indemnification Agreement shall be binding unless executed in writing by both parties hereto. No waiver of any provision of this Indemnification Agreement shall constitute a waiver of any other provision hereof. 19. The Indemnitee shall notify the Company in writing within thirty days after being served with any summons, citation, subpoena, complaint, indictment, information or other document relating to any matter concerning which the Indemnitee may be entitled to indemnification hereunder, but the failure to give such notice shall not affect the Company's obligation to indemnify the Indemnitee to the extent provided for herein or otherwise. 5

NABI BIOPHARMACEUTICALS - -------------------------------------------------------------------------------- EXHIBIT 10.35 Stonebridge Associates, LLC Ten Post Office Square, Boston, Massachusetts 02109 Investment Bankers October 22, 2002 Nabi Biopharmaceuticals 5800 Park of Commerce Blvd. N.W. Boca Raton, FL 33487 Attention: Thomas H. McLain Executive Vice President and Chief Operating Officer Re: Amended Letter Agreement Dear Ladies/Gentlemen: This amended letter agreement (the "Amended Agreement") effective as of August 31, 2002, hereby supersedes and replaces the former letter Agreement dated October 26, 2001 between the parties hereto (the "Agreement") confirming the engagement of Stonebridge Associates, LLC ("Stonebridge") as financial advisor to Nabi Biopharmaceuticals, formerly Nabi, (the "Company") in connection with the Company's review and implementation of a corporate expansion strategy. Under the terms of this Amended Agreement, the Company intends to engage Stonebridge to evaluate certain product or business acquisitions, joint venture, in-licensing, or other opportunities relating to four (4) specific potential business opportunities within Company's biopharmaceutical operations identified as 1. the Braintree Laboratories, Inc., PhosLo Product; 2. the Bayer Corporation/Aventis Behring LLC, Hyperimmune Products; 3. the MedImmune, Inc., Cytogam Product; and 4. any or all business activities of Cangene Corporation (the "Contemplated Transactions"). It is assumed that Nabi will explore these opportunities with the companies identified above ("Target Companies"). As provided in Section 3 below, Stonebridge shall also assist the Company in other activities relating to corporate partnerships and the development of a comprehensive strategic plan. The terms and conditions of Stonebridge providing financial advisory services are presented below. 1. FINANCIAL ADVISORY SERVICES: Stonebridge will work closely with Company to:

a. Assist in all aspects of the strategic review and financial analysis of the Contemplated Transactions consistent with the Company's current strategic planning process. b. Assist management in the financial and business due diligence investigation for each Contemplated Transaction. c. Assist management in preparing a consolidated business plan that incorporates each of the Contemplated Transactions into the Business Plan. d. Prepare a detailed financial valuation of each Contemplated Transaction to include i) Valuing such transaction to provide the basis of determining an appropriate consideration for such transaction. The basis of such valuation will include: a. A comparable company analysis which examines market valuation metrics of publicly traded companies with similar product or business activities; b. A comparable transaction analysis which examines acquisition valuation metrics for the purchase of similar product lines or for companies with similar business activities; and c. A discounted cash flow analysis that incorporates detailed financial projections for each transaction. ii) Valuing the Company today to provide a benchmark for assessing the shareholder impact of any Contemplated Transaction; and iii) Valuing the Company post-Contemplated Transaction, to reflect all strategic and operating synergies derived from the completion of each transaction. Such synergies to include, among others: a. Research and development; b. Clinical activities; c. Sales and marketing; d. Manufacturing; and e. Overhead utilization. f. Assist the Company in reviewing and evaluating a range of transaction structures and proposals. g. Advise the Company and actively participate in all discussions and negotiations with Target Companies. h. As needed, assist the Company and its legal counsel in the preparation of each Contemplated Transaction's purchase agreement and other legal documentation. 2

i. At the request of the Company or its Board of Directors, render an opinion in writing with respect to the fairness, from a financial point of view, of the consideration paid in each Contemplated Transaction. 2. INFORMATION: Stonebridge will not distribute information regarding a Contemplated Transaction or a Target Company (the "Information") other than to our employees and professional advisors directly involved in this engagement, nor will we distribute any information regarding the Company to any other party involved in a Contemplated Transaction without your prior approval, and without first obtaining a signed confidentiality agreement having terms acceptable to the Company. Stonebridge will keep strict control over the disposition of Company information, and attempt to retrieve all copies of such information given to parties who decide not to pursue a Contemplated Transaction. 3. COMPENSATION ARRANGEMENTS: As compensation for providing the financial advisory services outlined herein, Stonebridge will be entitled to the following fees: a) A monthly retainer of $40,000 for the months of August and September, 2002, and of $30,000, for October 2002 and each month thereafter, to be billed on a monthly basis on the thirtieth (30th) day of each month ("Financial Advisory Fee"); plus b) Once the cumulative consideration exchanged (as herein defined) in successful Contemplated Transactions reaches between $25 million and $75 million, 0.5% of all consideration received between $25 million and $75 million in Contemplated Transactions, (the "Transaction Success Fee"); and once the cumulative consideration exchanged in successful Contemplated Transactions reaches between $75 million and $100 million, the Transaction Success Fee would be 0.35% of all consideration received between $75 million and $100 million in Contemplated Transactions; and once the cumulative consideration exchanged in successful Contemplated Transactions reaches above $100 million, the Transaction Success Fee would be 0.2% of all consideration received above $100 million in Contemplated Transactions. There would be no Transaction Success Fee paid for cumulative consideration exchanged up to $25 million. Exhibit B, attached hereto, sets forth an example calculating the Transaction Success Fee. For purposes of calculating Stonebridge's Transaction Success Fee, consideration shall mean the sum of the cash, fair market value of any other securities, assets, obligations, or any other consideration agreed to be paid or provided by or on behalf of Company at the closing of the Contemplated Transaction, excluding future royalty payments and other deferred forms of payment. In addition, if requested by Company, a fairness opinion fee of $50,000 will be paid to Stonebridge upon their delivery of such opinion. Stonebridge will also support Company on its Gram-positive, NicVAX and Civacir partnering with financial and strategic analysis. There will be no Transaction Success Fee paid for this work, unless a partnering agreement includes a contribution of a product otherwise included in a Contemplated Transaction defined above in lieu of cash (for example: MedImmune, Inc. contributes Cytogam in lieu of an upfront payment). If this occurs, the 3

Transaction Success Fee would be based on the value of the product opportunity in accordance with subsection b above. Stonebridge will also assist with financial modeling and EVA analysis in support of the Nabi Biopharmaceuticals' 2003-2013 strategic plan as requested by Company. Stonebridge will bill the Company for analyst and associate time at a rate of $100 per hour up to a maximum amount, such that the total monthly fee (Financial Advisory Fee plus hourly charges) will not exceed $50,000 in any single month. Stonebridge will not charge the Company for any advisory or consulting services provided to the Company hereunder by professional personnel senior to an associate as part of this support. Additional projects may be added to the Contemplated Transactions only by the prior written agreement of both parties. In the event that the parties contemplate adding an additional project not specifically addressed by this proposal as part of this engagement, the Company and Stonebridge shall, in good faith, negotiate a mutually agreeable fee arrangement incorporating the general parameters of these fee arrangements specifically outlined in this proposal. 4. OUT OF POCKET EXPENSES: In addition to any fees that may be payable to Stonebridge hereunder (and regardless of whether a Contemplated Transaction occurs), the Company hereby agrees to reimburse Stonebridge monthly for reasonable travel and other out-of-pocket expenses incurred in performing its services hereunder. 5. INDEMNIFICATION PROVISIONS: The Company agrees to indemnify Stonebridge and related persons in accordance with the Standard Form of Indemnification Agreement attached hereto as Exhibit A, the provisions of which are incorporated herein by this reference. 6. RELIANCE ON REPORTS/ACCURACY OF INFORMATION: The Company agrees that Stonebridge shall be entitled to rely upon all reports of the Company or Target Companies and/or information supplied to Stonebridge by or on behalf of the Company or Target Companies (whether written or oral), and Stonebridge shall not in any respect be responsible for the accuracy or completeness of any such report or information or have any obligation to verify the same. 7. COMMUNICATION AND ADVERTISEMENTS: Stonebridge may not be quoted or referred to in any document, release or written or verbal communication prepared, issued or transmitted by the Company or any entity controlled by the Company, or any director, officer, employee, or agent thereof, without Stonebridge's prior written authorization. The Company agrees that, subsequent to the closing of a Contemplated Transaction, Stonebridge has the right at its own expense to place customary advertisements in financial and other newspapers and journals and to make mailings to its current, former or prospective clients describing its services to the Company hereunder. 8. CONFIDENTIAL USE OF INFORMATION OR ADVICE: The Company agrees that any information or advice rendered by Stonebridge or its representatives in connection with this engagement is for the confidential use of the Company and its Board of Directors only in its evaluation of a Contemplated Transaction and, except as otherwise required by law, the Company will not and will not permit any third party to disclose or otherwise refer to such advice or information in any manner without Stonebridge's prior written consent. The Company's Board of Directors and senior management will base their decisions on Stonebridge's 4

advice as well as on the advice of their legal, tax and other business advisors and other factors that they consider appropriate. Accordingly, as an independent contractor Stonebridge will not assume the responsibilities of a fiduciary to the Company or its shareholders in connection with the performance of Stonebridge's services. 9. ADMINISTRATION PROCEEDING AND LITIGATION: In the event of administrative proceeding or litigation in connection with the services provided by Stonebridge, Stonebridge agrees that its representatives will testify at the request of the Company or its counsel. Subject to the provisions of the Standard Form of Indemnification Agreement, the Company will reimburse Stonebridge for all out-of-pocket expenses reasonably incurred by Stonebridge in connection therewith, including the reasonable fees and disbursements of its legal counsel, and the Company will pay Stonebridge reasonable and customary additional compensation as agreed upon by Stonebridge and the Company to cover preparation for and the expenses of testifying at such litigation or proceeding, unless such proceeding or litigation resulted in whole or in part from the gross negligence or willful misconduct of Stonebridge, or the illegal conduct of Stonebridge or a breach by Stonebridge of a warranty herein. 10. TERM OF ENGAGEMENT: The term of Stonebridge's engagement as financial advisor to the Company shall commence on the date hereof and continue until the termination by either party, with or without cause, upon thirty days' prior written notice. In no event shall any termination of this Agreement affect the indemnification, contribution and confidentiality obligations of the Company the confidentiality obligation of Stonebridge, or the right of Stonebridge to receive any unpaid amounts due hereunder as of the date of termination or pursuant to the following sentence. Stonebridge shall be entitled to its appropriate success fees, in the event that any time prior to the expiration of twelve months after termination of this Agreement a Contemplated Transaction is consummated with any of the four (4) specified Target Companies contacted by Stonebridge or the Company pursuant to this Agreement or with any of the four (4) specified Target Companies which contacted the Company during the term of this Agreement. Upon termination of this Agreement, Stonebridge will provide to the Company a written list of all such specified Target Companies that have been contacted or have contacted the Company. 11. SOLE RECOURSE: The Company's sole recourse with respect to this Agreement for any matter relating to this Agreement shall be to Stonebridge and in no event shall the Company have any recourse or assert any claim against or seek recovery from any other Indemnified Party as defined in the Standard Form of Indemnification Agreement. 12. GOVERNING LAW/MISCELLANEOUS: This Agreement (a) shall be governed by and construed in accordance with the laws of the Commonwealth of Massachusetts without regard to conflicts of law principles, (b) incorporates the entire understanding of the parties with respect to the subject matter hereof and supersedes all previous agreements should they exist with respect thereto, (c) may not be amended or modified except in a writing executed by the Company and Stonebridge and (d) shall be binding upon and inure to the benefit of the Company, Stonebridge, any indemnified parties and their respective heirs, personal representatives, successors and assigns. Except as otherwise contemplated by Exhibit A hereto, nothing in this agreement is intended to confer upon any other person other than the parties hereto any rights or remedies hereunder or by reason hereof. 5

13. WARRANTY OF STONEBRIDGE: Stonebridge hereby represents and warrants that it is aware that U.S. securities laws prohibit any person who has material non-public information about a company from purchasing or selling securities of such company and further warrants that Stonebridge will not, and that Stonebridge has instructed its representatives that they should not, use the Information supplied pursuant to this Agreement in any way which may violate any securities or anti-trust law, and that Stonebridge will comply with all applicable provisions of all federal, state and local laws and all ordinances, rules and regulations thereunder. 14. DISCLOSURES REQUIRED BY LAW: In the event that Stonebridge is requested or required by law to disclose any of the Information, it is agreed that Stonebridge will provide Company with prompt prior notice of such request so that Company may seek an appropriate protective order and/or waive compliance with the provisions of the Agreement. This Agreement may be executed in two or more counterparts, each of which shall be deemed to be an original, but all of which shall constitute one and the same agreement. Please confirm that the foregoing is in accordance with your understanding by signing and returning to us a copy of this letter. Very truly yours, Stonebridge Associates, LLC /s/ Richard A.

EXHIBIT A STONEBRIDGE ASSOCIATES, LLC STANDARD FORM OF INDEMNIFICATION AGREEMENT In connection with the services Stonebridge Associates, LLC has agreed to render to the Company, the Company agrees to indemnify and hold harmless Stonebridge Associates, LLC, its officers, directors, employees, agents, managers, members, affiliates and persons deemed to be in control of Stonebridge Associates, LLC within the meaning of either Section 15 of the Securities Act of 1933, as amended, or Section 20 of the Securities Exchange Act of 1934, as amended (collectively, the "Indemnified Parties"), from and against any losses, claims, damages and liabilities, joint or several, related to or arising in any manner out of any transaction, proposal or any other matter (collectively the "Matters") contemplated by the engagement of Stonebridge Associates, LLC hereunder. The Company also will promptly reimburse the Indemnified Parties for any expenses (including fees and expenses of legal counsel) as incurred in connection with the investigation of, preparation for or defense of any pending or threatened claim related to or arising in any manner out of any Matter contemplated by the engagement of Stonebridge Associates, LLC hereunder, or any action or proceeding arising therefrom, whether or not resulting in liability (collectively, "Proceedings"). Notwithstanding the foregoing, the Company shall not be liable in respect of any losses, claims, damages, liabilities or expenses that a court of competent jurisdiction shall have determined by final judgment resulted solely from the gross negligence or willful misconduct of any Indemnified Party. Promptly after receipt by an Indemnified Party of notice of any claim or the commencement of any action or proceeding in respect of which indemnity may be sought against the Company, such Indemnified Party will notify the Company in writing of the receipt of commencement thereof, and the Company shall assume the defense of such action or proceeding (including the employment of counsel satisfactory to the Indemnified Party and the payment of the fees and expenses of such counsel), but the failure so to notify the Company will not relieve the Company from any liability which it may have to any Indemnified Party except to the extent of the Company's actual damages arising from the failure to so notify the Company. Notwithstanding the preceding sentence, the Indemnified Party will be entitled to employ its own counsel in such action if the Indemnified Party reasonably determines that a conflict of interest exists which makes representation by counsel chosen by the Company not advisable, it being understood, however, that the Company shall not be liable for the expense of more than one separate counsel (and one local counsel in each jurisdiction in which it is appropriate) to represent all Indemnified Parties. In such event, the fees and disbursements of such separate counsel will be paid by the Company. In no event shall the Company have any liability to an Indemnified Part for any settlement or compromise effected without the Company's written consent. 7

If for any reason the foregoing indemnity is unavailable to Stonebridge Associates, LLC or insufficient to hold Stonebridge Associates, LLC harmless, then the Company shall contribute to the amount paid or payable by Stonebridge Associates, LLC as a result of such claims, liabilities, losses, damages or expenses in such proportion as is appropriate to reflect not only the relative benefits received by the Company on the one hand and Stonebridge Associates, LLC on the other but also the relative fault of the Company and Stonebridge Associates, LLC, as well as any relevant equitable consideration. It is hereby further agreed that the relative benefits to the Company on the one hand and Stonebridge Associates, LLC on the other hand with respect to the transactions contemplated in this engagement letter shall be deemed to be in the same proportion as (i) the total value of the transaction bears to (ii) the fees paid to Stonebridge Associates, LLC with respect to such transaction. The indemnity, contribution and expense reimbursement agreements and obligations set forth herein shall apply whether or not an Indemnified Party is a formal party to any Proceeding, shall be in addition to any other rights, remedies or indemnification which any Indemnified Party may have or be entitled to at common law or otherwise, and shall remain operative and in full force and effect regardless of any investigation made by or on behalf of any Indemnified Party or any withdrawal, termination or consummation of or failure to initiate or consummate any Matter or any termination or completion or expiration of this letter or Stonebridge Associates, LLC's engagement. 8
