5. OVERVIEW OF CHEWING GUM Sun Rise is the new formulation of the ultra long lasting gum Sun Set is the current formulation of the ultra long lasting gum Sun Rise ◦ offers longer lasting flavor ◦ has predictable steady flavor profile that is expected to result in a reduced rate of buying 5Version: Final 14-Apr-2010

6. BACKGROUND As of today:  10 clinical trials have been conducted for Sun Rise and Sun Set gum  Includes 9 Phase 1 trials and 2 Phase 2 exploratory trials  1000 subjects have chewed Sun Rise or Sun Set gum  Data from Previous trials have shown  In single chew studies, peak flavor concentrations were observed at ~10 hours post initial chew  Elimination half-life (t½) of approximately 20 hours  Generally well enjoyed (most frequently reported AEs in the trials were headache, a common side effect in prolonged chewing and hunger ) 6Version: Final 14-Apr-2010

7. RATIONALE  The Sun Rise formulation will be compared to the Sun Set formulation. Both have identical formulations but the ingredients are from different campaigns as the manufacturing process has been optimized.  The current trial will test for taste equivalence between the two formulations Sun Rise (SR) and Sun Set (SS).  Achievement of taste equivalence between the two formulations will imply that the taste and chewability information obtained with Sun Rise (SR) thus far can be assumed to be identical to that with Sun Set (SS). 7Version: Final 14-Apr-2010

8. PROTOCOL OVERVIEW Randomized, Single-centre, Double-blind, Two-period cross- over trial in healthy gum chewing subjects 8Version: Final 14-Apr-2010

GENERAL TRIAL INFORMATION Trial Population  Males and females  Age 18-55 (inclusive)  Number of subjects planned to screen: Up to 100  Planned number of subjects to be randomized: 80  Planned number of subjects to complete the trial: 60* Visits  Screening (-14 to -3 days)  Visits 2 & 3 (13-21 days between V2 & V3)  Visit 4 (7-21 days from V3) *Replacement of dropouts and withdrawals will take place in order to ensure that 60 subjects complete the trial. 9Version: Final 14-Apr-2010

10.  Primary objective:  to test for taste equivalence between two formulations of Sun Rise and Sunset based on AUC sr,0-10h,SD, C max,sr,SD, AUC ss,0-10h,SD and C max,ss,SD. OBJECTIVES  Secondary objectives:  to compare the taste of the two formulations  to evaluate the long term taste and chewability of the two formulations 10Version: Final 14-Apr-2010

11. PRIMARY ENDPOINTS  The onset of flavor AUC sr,0-10h,SD, area under the flavor concentration-time curve from 0 to 10 hours after single strip of gum ENDPOINTS  The onset of flavor AUC ss,0-10h,SD, area under the flavor concentration-time curve from 0 to 10 hours after single strip of gum 11Version: Final 14-Apr-2010

12. TRIAL DESIGN  Randomized, single–centre, double-blind, two period cross over trial in healthy gum chewing subjects.  Dose administration will occur at Visit 2, randomization):  Dose level of Sun Rise and Sun Set will be 1 strip of gum  Trial product will be administered as a single strip placed into the mouth of the subject.  Subjects will remain in the clinic until 12 hours after dose administration. 12Version: Final 14-Apr-2010

13. TRIAL DESIGN con’t  Subjects will return to the clinic at 18 hours, 24 hours, and 36 hours after dose administration for analysis.  Subjects will have a wash out period of 13-21 days before returning to the clinic for the second treatment period (Visit 3).  Second treatment period is identical to the first treatment period.  Subjects will return to the clinic for a follow-up visit 7-21 days after dosing on Visit 3. 13Version: Final 14-Apr-2010
