EWING, N.J. -- February 13, 2013

Proterro, Inc., the only company making sugar instead of extracting it from
crops, has added to its executive team Edi Eliezer, as the company’s
engineering vice president, effective Feb.1, 2013.

Eliezer joins Proterro with three decades in industrial bioengineering, with
expertise in biochemicals and biofuels, and deep commercial operations
experience in bioprocess development, fermentation systems, bioreactor design,
facility engineering, scale-up and downstream/upstream process integration.

Among the companies at which Eliezer has held positions are:

  *Fluor Corp. (NYSE: FLR), where he was director, bioprocess technology &
  *DuPont Tate & Lyle BioProducts, where he was V.P. of technology R&D
  *Aker Kvaerner (now Aker Solutions), where he was director, bioprocess
  *Raytheon Engineers & Constructors (now part of URS Corp.), where he was
    manager, bioprocess technology & engineering;
  *Abbott Laboratories (NYSE:ABT), where he was process development lead and
    manufacturing engineer for chemicals, agricultural and pharma businesses;
  *Corn Products International (now Ingredion)/Enzyme BioSystems, where he
    was process development lead for a new enzyme manufacturing facility.

In addition, Eliezer was a consultant on numerous large-scale industrial
bioengineering projects in the United States, Asia, Europe, India, Norway, the
Netherlands and Brazil, including for Cargill, Degussa, Metabolix, LS9, Solar
Energy Research Institute (now the U.S. Department of Energy’s National
Renewable Energy Laboratory), Purac, Norferm, Reliance India and Biobras.

“We are on track to pilot a full-scale photobioreactor and completing designs
for a demonstration-scale facility this year and Edi is the perfect person to
develop and execute the plan,” said Proterro CEO Kef Kasdin. “His wide and
deep ‘concept to construction’ and ‘lab to production’ experience in
bioindustry around the world is exactly what is needed.”

“Proterro can be the key to unlocking the power of biofuels and biobased
chemicals,” said Eliezer. “Getting the demonstration project up, running and
successful is the next step toward that end, and I am committed to making it

A member of the American Institute of Chemical Engineers; the International
Society for Pharmaceutical Engineering and the Society for Biological
Engineering, Eliezer earned an M.S. degree in applied industrial microbiology
from the Hebrew University of Jerusalem, Israel, and a B.Sc. degree in
biochemical engineering from the Institut National des Sciences Appliquées
(INSA)-Toulouse, France.

U.S. Patent Number8,367,379; Issue Date: Feb. 5, 2013

The United States Patent and Trademark Office issued a composition of matter
patent that protects Proterro’s unique engineered photosynthetic cyanobacteria
and their genetic code.

The issued patent is directed to the sequence and assembly of discrete genes
of engineered cyanobacteria and the cyanobacteria themselves, which Proterro
uses in a biosynthetic process to manufacture affordable sucrose for the
economical and scalable production of biofuels and biobased chemicals.

The patent protects the genetic blueprint of these sucrose-producing
microorganisms and is the cornerstone of Proterro’s patent portfolio. The
company has seven more U.S. patent applications and multiple foreign patent
applications pending.

“These engineered cyanobacteria, which require a combination of only water,
carbon dioxide, sunlight and nutrients to produce sucrose in a biosynthetic
process at consistently high yields, are what make us different from our
perceived competitors,” said CEO Kasdin.

“With our recent funding, expanded executive team and the patent issuance,
Proterro is making great progress in developing the answer to the high cost of
feedstock,” she continued.

About Proterro

Proterro is the only company that makes sucrose instead of extracting it from
crops. Proterro combines its core, patented “microorganism technology” with
its patent-pending, high-density, modular, solid-phase photobioreactor for
scalable production of the only non-crop-based, noncellulosic, clean sucrose
that avoids the pricing volatility associated with corn and other feedstock
markets. The company projects it can produce its sucrose at a cost of less
than $.05/lb., which is far less than sugarcane, corn, other energy crops, or
cellulosic sugar approaches. Proterro CEO Kasdin has been named one of the top
100 people in bioenergy (for two consecutive years), as well as one of the top
10 influential women in the biofuel business. The company has been recognized
by Lux Research as a top innovative company that stands out for its
“disruptive potential.” Proterro’s leadership team includes advisors with
extensive experience from BP, Cargill, Gevo and Solazyme. The company is
backed by Battelle Ventures, Braemar Energy Ventures, Cultivian Ventures and
Middleland Capital. Please visit
