- 7 -



---

13.1 Except as provided for in this section, all disputes between the
parties that are, in any way, connected to this Agreement, shall be resolved by arbitration only. Unless both parties agree, arbitration shall be conducted only before the American Arbitration Association (the AAA) and only in the Salt
Lake City metropolitan area. If either party, however, believes that it will suffer irreparable damage as a result of the actions of the other party, it may seek injunctive relief, but only injunctive relief in any state or federal court in Utah or
in any state where the alleged activity is alleged to have occurred; any other relief must be through arbitration.

13.2 As a condition precedent to the filing of any claim to initiate an arbitration proceeding, the party that believes that a breach (i.e., a default) of this Agreement has occurred, shall provide notice
of the breach and 15 calendar days and an opportunity to cure that breach or otherwise satisfy the complaining party that no claim is necessary. If the party giving the notice is not satisfied, either party may then file an arbitration claim. The
notice shall be in sufficient detail to fairly and reasonably apprise the other of each alleged material default.

13.3 Each party shall bear their own costs in relation to any court or arbitration proceeding arising under this Agreement. All arbitration shall be conducted by a panel of three arbitrators, with one
arbitrator being selected by each party and the two arbitrators jointly choosing the third arbitrator; an arbitration award shall contain a reasonably narrative explanation of its decision.

14. Please acknowledge your acceptance and understanding of this Agreement by signing and returning it to the undersigned. A copy of this
signed Agreement will be sent to you for your records.

ACKNOWLEDGED AND AGREED,

LifeVantage Corporation
