Richard Gonzalez, Chairman and CEO Rick Gonzalez is a 30-year veteran who led Abbott’s global pharmaceutical division (R&D, commercial operations, manufacturing). Under his leadership, the division flourished as a profitable business, consistently delivering strong performance. Over this tenure, Rick oversaw the successful integration of assets from major acquisitions such as Solvay Pharmaceuticals, Kos Pharmaceuticals, Perclose, TheraSense, and Guidant’s vascular business. He led the strategy to establish AbbVie as a global, independent biopharmaceutical company currently operating in 170 countries worldwide. In its first year, Rick led AbbVie to deliver 60 percent total shareholder return (nearly 2x S&P 500) and increase pipeline investment by 22 percent (Q1 ’13 vs Q1 ’14). Rick played a key role in driving the clinical and commercial development of the prescription biologic Humira, a product that now generates more than $10 billion per year in sales. Prior Abbott roles included: President and Chief Operating Officer; President and Chief Operating Officer of the Medical Products Group; Senior Vice President and President of the former Hospital Products Division (now Hospira, Inc.); Vice President and President of the Health Systems Division; and Divisional Vice President and General Manager for Diagnostics Operations in the United States and Canada. 2

AbbVie Pipeline Snapshot 4 Our pipeline continues to advance in 2014 with numerous data milestones, regulatory submissions and phase transitions, including the initiation of a Phase III trial for veliparib in non-small cell lung cancer. Additionally, for AbbVie’s interferon-free HCV combination, the US FDA recently granted a priority review and the European Medicines Agency validated and placed it under accelerated review.

As Abbvie has announced three deals to grow our pipeline and advance leadership in key therapeutic areas Ablynx: a global license agreement to develop and commercialize the anti-IL-6R Nanobody, ALX-0061, to treat inflammatory diseases. ALX-0061 successfully completed a Phase IIa study in February 2013 in patients with moderately to severely active rheumatoid arthritis (RA). This collaboration builds on AbbVie's expertise and leadership in the field of RA – Sept. 2013 Galapagos: a global alliance to discover, develop and commercialize novel potentiator and combination therapies in cystic fibrosis (CF), an inherited chronic disease that affects 70,000 people worldwide. AbbVie and Galapagos will work collaboratively to contribute technologies and resources in order to develop and commercialize oral drugs that address the main mutations in CF patients, including F508del and G551D. This collaboration builds on AbbVie’s expertise and leadership in CF. – Sept. 2013 Alvine: a global collaboration to develop a novel oral treatment for patients with celiac disease, currently in Phase II development. ALV003 is an investigational oral therapy composed of two recombinant, gluten specific enzymes (a cysteine protease (EP-B2) and a prolyl endopeptidase (PEP)), that degrade gluten in-vitro and in human clinical testing, and may reduce the symptoms and intestinal injury associated with celiac disease in patients attempting to adhere to a gluten-free diet. Data from a Phase 2a study reported at Digestive Disease Week (DDW) 2012, showed reduction of intestinal inflammation in patients exposed to gluten and treated with ALV003 compared to patients treated with placebo. This collaboration builds on AbbVie's expertise and leadership in the field of gastroenterology with its on-market products to treat Crohn's disease, ulcerative colitis, and diseases associated with exocrine pancreatic insufficiency. – May 2013 5
