Exhibit E

Label Guidelines

Guidelines on Use of T-Hexx Trademark and the design of Product Labels

____ Do follow the first prominent use of the mark with a ". Its OK to put " or
tm after each use thereafter but its not necessary.

____ Use the trademark as an adjective, not as a noun. Avoid such use as "put
T-HEXX tm on the teat", say "put T-HEXX tm solution on the teat"

____ Don't confuse a trade mark with a tradename. Hydromer", Inc. is improper as
the word Hydromer is being used to identify the Company. Conversely, Hydromer"
cow teat dip would be identifying the PRODUCT as to its source. Then Hydromer is
being used as a trademark.

____ Do give credit to all the trademarks of on the label. Example "Dermaseal"
is a trademark of Hydromer, Inc."

____ Do not place unknown trademarks on a label. International graphics are in
the public domain but each trademark on a label must be justified as to owner.

____ Don't string trademarks together. It confuses the consumer or buyer as to
the source. Example of stringed trademarks "Fargo" T-Hexx tm teat dip"

____ On T-Hexx labels which represent a custom label for a distributor, the
distributor's trademark should not exceed 150% of the size of the T-HEXX mark .
A distribution trademark should never appear as if the source is the
distributor.

____ Don't makeup or create trademarks. Before using a trademark it must be
searched. A search generally runs US$250-$500 per class plus attorney's fees and
takes 1-2 weeks for a comprehensive search in the USA. Foreign trademarks
searches can run US$500 per country plus fees. Each distributor must use its own
attorney for an opinion.

____ Avoid using the mark generically. Example. "T-Hexx that cow". The solution
may not be T-Hexx.

____ Have a legal review of a printers' proof of the label. Hydromer's legal
department MUST see the printer's proof before any labels are printed.
Turnaround will no more then 48 hours and generally 4 hours or less from receipt
of print proof (not a fax). Ask the printer for two proofs.
