Newport Beach, CA – September 11, 2008 – Marwit Capital Partners II, L.P. (“Marwit”)
announced today that it has recapitalized Granite Seed Company (the “Company”) in
partnership with Founder & CEO, Don Bermant. Mr. Bermant and his management team will
continue to lead the Company post-transaction in its current facilities in Lehi, UT.

Founded by Mr. Bermant in 1988, Granite Seed is recognized as the leading one-stop
supplier of conservation seed and erosion control solutions in the Western U.S. The
Company’s products and services are used for complex land reclamation, revegetation, and
erosion prevention associated with disturbances caused by energy exploration, infrastructure
development, commercial construction, and rangeland wildfires. Granite Seed’s products and
value-added services offer important solutions for customers that include oil and gas
corporations, mining companies, regional contractors, and Federal, State and Local
Government Agencies.

Under the guidance of Mr. Bermant, the Company has a long track record of profitable
growth by providing products and services that enable commercial and government
customers to solve their complex environmental needs and responsibilities. Mr. Bermant,
CEO, said, “With Marwit as our new financial partner, the Company is now poised to expand
its leadership position in the conservation seed industry, growing organically and through
select acquisitions. This is an exciting time at Granite Seed.”

Matt Witte, Managing Partner of Marwit stated, “Marwit was interested in investing in an
environmentally focused, green business with strong growth potential. After evaluating many
sectors and numerous companies, we met Don Bermant and his management team, and
were immediately sold on the opportunity.” He continued, “Not only is Granite Seed the clear
leader in its markets, but industry dynamics, particularly increased energy exploration and
infrastructure development, are accelerating the need for seed and erosion control products
and services.” Rob Wendell, Principal of Marwit added, “With its strong reputation and
excellent management team, Granite Seed is an outstanding platform for a broader native
seed and erosion control strategy. Following Don’s lead, we have already begun substantive
discussions with other high quality companies that will enhance the Company’s ability to gain
a stronghold in other strategic regions throughout the country.”
