Longer Product Life Cycles

Differentiated products can be “sticky” and difficult to

replace

Difficult formulations results in fewer future entrants to

market, which leads to better price consistency and longer

life cycles

Current capacity fully supports growth through 2018

Significant excess capacity exists, based on nominal

capacity

By 2018 only two out of five lines are projected to

approach full capacity

Further ability to expand by adding production lines

Rochester facility has ample additional space

JHP will enjoy strong operating leverage as incremental products do not incur additional fixed costs

Unique Strategy and Competitive Position

Par

Pharma

Specializing in “niche,” high barrier-to-entry products: Difficult to manufacture and/or complex legal challenges; tend to be more profitable and long-lived products

Focus on first to file (FTF) or first to market (FTM): Leverages strong formulation capabilities to drive short- term profit and long-term market positioning

“Partner of choice”: Partner with large branded pharmaceutical companies and “big four” generics (who are often reticent to partner with one another)

Building a strong product pipeline: Pursuing 15-20 ANDAs / year

Manufacturing and product selection flexibilities through 3 facilities in NJ, California, and India

Strong track record of reliable supply and regulatory compliance
