Naturally Advanced Technologies And Cintas Corporation Enter Into Development Agreement For CRAiLAR Flax Fiber In The Corporate Identity Uniform Market

PORTLAND, Ore. and VANCOUVER, B.C. — June 7, 2011 — Naturally Advanced Technologies Inc. (NAT)
today announced that it has entered into a short-term CRAiLAR® Flax fiber development agreement
with Cintas Corporation beginning June 2011 to support evaluation of processing CRAiLAR flax fiber
in corporate identity uniform programs.

“Cintas is the leading uniform brand in the U.S. and we are looking forward to supporting
their manufacturing processes,” said Ken Barker, CEO of NAT. “This agreement is further validation
that NAT promises a significant impact for global corporations from both a sustainability and
performance standpoint. We look forward to showing Cintas how CRAiLAR can perform across its
product categories.”

Based on previous testing, the companies expect CRAiLAR Flax fiber to deliver increased
durability and longevity to the uniform market due to the tensile strength of CRAiLAR. In addition,
CRAiLAR’s ability to wick moisture should provide users of Cintas uniforms a more comfortable
uniform to wear in hot summer months.

Since March, NAT has announced a 10-year purchasing agreement with Hanesbrands, along with
development agreements with Georgia-Pacific and Levi’s. Hanes represented the first
commercialization agreement for its CRAiLAR flax fiber. They anticipate further marketing plans for
Hanes to be announced later this year.
