ToxExpo Rules and Regulations
Exhibitors agree to abide by the contract conditions published herein and on the Society of Toxicology (SOT) website and by all conditions stipulated by the Music City Center. Exhibitors accept responsibility for informing their employees and agents of these conditions and agree that they will abide by them as well.
ELIGIBILITY FOR EXHIBITING
The purpose of the SOT exhibit program is to further the education of scientists working in the field of toxicology. Exhibits must be of an educational character and must emphasize instruments, products, or services for use in teaching or research. Books or other publications in fields of relevance to the professional interests of SOT's members and meeting registrants are also considered acceptable.
The very foundation of SOT is to create a safer, healthier world by advancing the science and increasing the impact of toxicology. To this end, SOT reserves the right to deny an exhibit space request from any organization whose goals, objectives, or past actions are deemed counterproductive to those of SOT.
ENFORCEMENT OF RULES AND REGULATIONS
The Rules and Regulations of the SOT Annual Meeting and ToxExpo are intended to bring order and fairness to the medium. Exhibitors are cautioned to observe these Rules and Regulations. Should an exhibitor fail to comply with these or any other posted or published Rules and Regulations or any amendments thereto, SOT may require immediate removal of the exhibit of the offending exhibitor, who may at SOT's election, forfeit all rights to exhibit at future ToxExpo events together with all fees and rentals paid. SOT may assign any space so forfeited to another exhibitor. SOT reserves the right to evict any exhibitor found in violation of these Rules and Regulations. In the event of such eviction, SOT is not liable for any refunds or rental or other expenses, and exhibitors who violate regulations will be subject to the following sanctions:
- 1st violation – Loss of current year priority point.
- 2nd violation – Loss of one-half accrued points.
- 3rd violation – Loss of remainder of points.
- 4th violation – One-year suspension of exhibit privilege.
Note: Exhibitors who dismantle before 4:30 PM, Wednesday, March 22, will be subject to a loss of priority points and a one-year suspension of exhibit privilege.
APPLICATION OF EXHIBIT SPACE
Application for exhibit space is subject to the approval of the SOT Council, and SOT reserves the right to refuse applications not meeting standards required or expected, as well as the right to curtail or to close exhibits or parts of exhibits that reflect unfavorably on the character of the meeting. This applies to displays, literature, advertising, novelties, souvenirs, conduct of persons, etc.
PRIORITY POINTS SYSTEM
Exhibit space sales will be conducted on a priority point-based system. Exhibitors receive one point for each year of exhibiting, regardless of the number of 10' x 10' exhibit spaces utilized. If an exhibitor does not exhibit for two or more consecutive years, their priority points will be returned to zero. In the case of company mergers or acquisitions of another exhibiting company, SOT will use the higher number of points accumulated by either company. The ToxExpo Senior Exhibits Manager must be notified in writing of company mergers or acquisitions and include a public announcement of the transaction.
