(For purposes of clarity, publication of research results is not intended to be restricted.) Notwithstanding the foregoing, the retained rights of the University do not include the right to practice rights under or use the Biological Materials under sponsorship of or in collaboration with a commercial entity if such commercial entity will receive rights to use Biological Materials directly or indirectly for any commercial purpose (as compared to for purposes of research or scientific investigation).

I hereby agree and certify on behalf of the undersigned agency, university or company (“Company”) as follows:

SELECT AGENT AND TOXINS REGULATIONS

Please select ONE category that applies:

o                 The Materials are select agents or toxins subject to transfer procedures. UMass Dartmouth and Company must complete APHIS/CDC Form 2. 1 certify that Company is an entity registered with the CDC or APHIS.

o                 The Materials are select agents or toxins, but the amount to be transferred qualifies for the exempt quantities exemption. I certify that, upon Company’s receipt of the Materials, the Materials will be under the control of a principal investigator, treating physician or veterinarian, or commercial manufacturer or distributor and that the aggregate amount of Materials in the Company’s inventory (including any materials already in his/her possession prior to this shipment) shall at no time exceed [botulinum toxin 0.5 mg] [clostridium perfringens epsilon toxin 100 mg].

o                 The Materials are not select agents or toxins because they comprise rDNA derived non-toxic subunits recognized by the CDC as being non-toxic under an exemption issued to UMass Dartmouth.

EXPORT CONTROL REGULATIONS

I acknowledge that the Materials are subject to Department of Commerce export controls described in the Commerce Control List under ECCN 1C351.
