 LPCN 1021 is a novel oral testosterone undecanoate formulation  Utilizes a novel lipid based oral delivery technology allowing twice - daily dosing with standard meal leading to: • Improved solubilization • High drug - loading capacity LPCN 1021 – Novel Technology 3

SOAR Study Design [ NCT02081300] 4 Screening N=315 0 Week 3/4 Week 7/8 Randomization LPCN 1021 225 mg TU BID with meal (n=210 ) Active control: Androgel ® 1.62% (n=105 ) PK/Dose Titration PK/Dose Titration PK/Efficacy Assessment Safety Assessment Week 13 Week 52 Safety Extension (up to Week 52) Open - label, randomized, active - controlled study of LPCN 1021 in 18 - 80 year - old hypogonadal men ( T <300 ng/dL on 2 separate days )

 The starting dose of LPCN 1021 was 225 mg TU BID taken with a standard meal  The dose could be titrated at weeks 4 and 8 • up to 300 mg BID (if T C avg,24h was <300 ng/dL ) or • down to 150 mg BID (if T C max was >1500 ng/dL and/or C avg,24h >1140 ng/dL) LPCN 1021 Dosing 6

Primary Outcome 7 Measure [Week 13] FDA Threshold Frequency, n (%)* Geometric Mean (ng/dl); Variance C avg,24h within 300 - 1140 ng/dL ≥75% 134 ( 88.2) 447 (37%) 95% CI lower bound ≥65% 81.9 C avg,24h below 300 ng/dL 17 ( 11.2) C avg,24h above 1140 ng/dL 1 ( 0.7)  T levels are reliably restored and maintained in eugonadal range (300 - 1140 ng/dL) for hypogonadal men *Dataset: Efficacy population (subjects with ≥1 PK profile and no major protocol deviations; n=152 LPCN 1021)

Secondary Outcome 8 Measure FDA Threshold Frequency % (n)* Geometric Mean (ng/dl); CV C max < 1500 ng/ dL ≥ 85% 82.9%(126) 1128 (45%) 1800 ≤ C max ≤ 2500 ng/ dL ≤ 5% 4.6% (7) C max > 2500 ng/dL None 2.0% (3)  Proportion of subjects with maximum serum levels and any observed supra – physiological levels are generally consistent with approved TRT products *Dataset: Efficacy population (n = 152)

Serious Adverse Events (SAEs) 11  As of April 30 th , 2015 • No drug related SAEs • No cardiac related SAEs

 LPCN 1021 is an orally administered product for T replacement with acceptable C avg levels, consistent with US FDA target guidelines • C max levels were generally consistent with US FDA target guidelines  LPCN 1021 may improve patient compliance as a generally safe, effective, and more convenient option compared to topical, transdermal, injectable, or implanted testosterone products Conclusions 12
