Used Oil Re-Refining

wRe-Refining = Treating used oil to remove impurities so that it can be
used as a base lube oil for new lubricating oil

wRe-Refining prolongs the life of the oil resource indefinitely

wRe-Refining is the preferred environmental option per U.S. EPA

wModern re-refineries employ two main processing steps borrowed from
the refining industry:

§Vacuum distillation to remove the base lube oil, followed by

§Hydrotreating to remove trace impurities from the base lube oil

Environmental Benefits of Re-Refining

Environmental Benefits of Re-Refining

wRe-Refining requires 1/3 the energy compared to producing lube oil
from crude oil1

w2 ½ quarts of lube oil can be extracted from 42 gallons of crude oil or
from 1 gallon of used oil1

wRe-Refining meets the federal definition of waste minimization, a goal
of many pollution prevention programs

wRe-Refining reduces U.S. dependence on imported crude oil

wRe-Refining reduces air pollution and carbon emissions

HCCI Management Experience with Re-Refining

wHCCI Management helped create North American re-refining industry

wDesigned, built and operated two largest re-refineries in North America
(currently owned by Safety-Kleen) representing 75% of industry
capacity

wThese two re-refineries continue to operate successfully and profitably

HCCI Experience

wJoe Chalhoub, HCCI President and CEO

§Chemical Engineer & Entrepreneur

§1977 started Breslube Enterprises re-refinery in Ontario, Canada

§1987 sold controlling interest in Breslube to Safety-Kleen, remained with business

§1991 led design and construction of SK E. Chicago re-refinery

§Recognized leader in North American re-refining

wGreg Ray, HCCI VP Business Management and CFO

§1984 helped start Evergreen Oil re-refining business in California

§1987 oversaw growth of Evergreen’s used oil collection business

§1994 joined Safety-Kleen and took responsibility for used oil collection, expanding to
create first nationwide used oil service

§Led or managed numerous acquisitions including #2 and #3 used oil collectors in U.S.

History of Re-Refining in U.S.

HCCI Used Oil Re-Refining March 2010

Oil Recycling History in USA

wBy 1960’s, the industry claimed more than 160 re-refiners

wIncreasing additive content of lubricants and tightening environmental
regulations caused them to exit industry

wRising crude prices in 1970’s (due to geopolitical events) led to
renewed interest in re-refining

wBy 1980’s, several modern re-refiners using hydrotreating started in 
   the U.S. and Canada: Breslube, Evergreen, Mohawk

wIn 1990’s, Executive Orders 13101 and 13149 encouraged U.S.
government procurement of re-refined oil products

Oil Recycling 2001 to Present

wWorld crude oil prices climb to $70+/barrel

wModest capacity additions at existing re-refiners

wSome new entrants to re-refining business:

–Heartland (20 MM gpy)

–Universal (12 MM gpy)

–Bango (initially < 10 MM gpy)

wRe-refining margins are attractive based on current market conditions,
but this remains a complex business requiring competency with
collection, technology, operations, and product sales

Used Oil Collection

wOur goal is to collect enough feedstock to ensure self-sufficient plant
operation

wUsed oil can be collected from wide geography but transportation
economics are important; a large branch network is key

wOperation of many trucks serving thousands of generators requires
significant investment in infrastructure and management

wMost often, customers are looking for used oil collector to provide a
menu of corollary services, adding complexity to the business

HCCI Used Oil Re-Refining March 2010

23

Re-Refining Technology

wProduction of marketable lubricating base oil requires hydrotreating, a
process practiced at major refineries that adds significant complexity
and capital cost

wSeveral EPC firms willing to license re-refining technology and designs
including distillation and hydrotreating

wCritical issues are operability, economies of scale, and capital cost

wInconsistency of used oil feedstock, including industrial waste
contaminants, creates need for screening and testing programs and
robust process

wOther firms with less experience have been unable to deliver
acceptable performance in commercial scale plants

HCCI Used Oil Re-Refining March 2010

24

Lube Product Sales

wWe expect our re-refinery will produce high quality lubricating base oils

wProduct acceptance will require engine sequence testing to
demonstrate API/SAE performance

wMarketing plan includes base oil sales to independent
blenders/compounders

wLonger term opportunities to go downstream and sell blended and
packaged lubricants

Re-Refining Pros and Cons for HCCI

Pros

wLeverages HCCI branch infrastructure
& customer base

wHCCI management expertise

wExpected to accelerate HCCI growth in
revenue and earnings

wStrengthens quality of HCCI service
offer menu

wPotential to add many customers and
address very large market

Cons

wSwings in crude and lube market prices
will add volatility to HCCI revenue and
earnings

wRe-refining is more capital-intensive
than other HCCI service-only
businesses

Conclusions

HCCI Used Oil Re-Refining March 2010

27

Conclusions

wWe believe that HCCI has an excellent opportunity to leverage its branch network,
customer base, and management expertise through the development of a re-refinery

wThe HCCI re-refinery is expected to deliver meaningfully accretive growth in revenue
and profits

wWhile HCCI will become more sensitive to swings in crude and lube prices, we intend
to report statistics to allow investors to understand the sensitivities and performance
of each component of our business

wIt will require approximately two years to build the re-refinery, and we intend to use
that time to expand our used oil collection program

wSuccess in re-refining requires competency with all three aspects of the success
triangle - - collection, processing, and product sales - and we believe that HCCI has
these capabilities
