NORWELL, Mass.--(Business Wire)--
Clean Harbors, Inc. (NYSE: CLH), the leading provider of environmental and
hazardous waste management services throughout North America,today announced
that it has signed a definitive agreement to acquire Eveready Inc. (TSX: EIS), a
Canadian-based company that provides industrial maintenance and production,
lodging, and exploration services to the oil and gas, chemical, pulp and paper,
manufacturing and power generation industries. Under the terms of the agreement,
Clean Harbors will purchase Eveready through a combination of cash, stock and
assumed debt. In total, the transaction is currently valued at approximately USD
$387 million, based on an agreed upon price for Clean Harbors` common stock of
USD $48.81 per share. The acquisition is subject to approval by regulators,
lenders and Eveready shareholders, as well as other customary closing
conditions, and is expected to be completed during the third quarter of 2009.
Eveready executive officers and shareholders holding a total of 26% of the total
outstanding Eveready shares have entered into a voting and lock-up agreement
with Clean Harbors under which they have agreed to vote their shares in favor of
the acquisition.

Under the terms of the agreement, Clean Harbors will acquire 100% of Eveready`s
outstanding common shares in exchange for USD $49 million in cash (approximately
USD $2.64 for each Eveready share), USD $118 million in Clean Harbors` common
stock consisting of 2.4 million shares (a ratio of 0.1304 Clean Harbors shares
for each Eveready share), and the assumption of approximately USD $220 million
of Eveready debt. Clean Harbors expects the acquisition will be immediately
accretive, excluding any one-time fees and acquisition-related expenses.

"This transaction represents another major milestone as we build our Company`s
future and create long-term value for our shareholders," said Alan S. McKim,
Clean Harbors` Chairman and Chief Executive Officer. "The acquisition of
Eveready greatly enhances our presence in the attractive industrial services
market and broadens the range of services we can offer customers of both
companies. We envision substantial cross-selling opportunities with Eveready`s
blue-chip customer base, particularly with respect to refineries and other
energy companies. Geographically, this transaction will significantly advance
our position in the Canadian marketplace, and affords us with expanded service
offerings in our existing U.S. and Canadian locations. It also will provide us
with our first foothold in markets beyond North America through the services
Eveready now offers to refineries in Europe, South America and Asia."

"Successful acquisitions in our industry rely on purchasing businesses with
steady revenue streams, talented employees, a good safety record, and
well-maintained vehicles and equipment," McKim said. "This transaction meets all
of these criteria. The quality of Eveready`s assets and its personnel are an
important factor in our decision to acquire the company. We see this as an
excellent cultural fit for our two organizations."

Rod Marlin, Eveready`s President and Chief Executive Officer, said, "We believe
that this transaction is a win/win scenario for our employees, customers and
shareholders. Our employees will become part of a larger, growth-oriented
organization that is a well-managed industry leader. Eveready customers will now
have access to a broader spectrum of environmental and industrial services,
through a single source. In addition to the cash they receive, our shareholders
will participate in the future growth of the top environmental services company
in North America, whose value has been significantly enhanced by the acquisition
of our organization. Eveready`s Board of Directors fully supports this
transaction and will strongly recommend it to our shareholders."

Operating from 79 locations in Canada, the United States, and internationally,
Eveready currently employs over 2,100 employees and operates a service fleet of
over 2,400 truck and trailer units. The company generated CAD $651 million (USD
$614 million) in revenues and CAD $109 million (USD $103 million) of EBITDA in
2008. This currency exchange rate reflects the average daily exchange rate for
2008. Due to the current economic environment, Eveready has previously announced
that it expects its revenues in 2009 to be as much as 10 percentlower thanin
2008.

"For nearly three decades, Clean Harbors has been on the leading edge of
technology and innovation within our industry," McKim said. "We believe that
integrating Eveready`s operations with our best-in-class systems and processes
will result in sizeable benefits in areas of efficiency and utilization. In
addition, this acquisition will afford us with new platforms for growth. We are
excited about adding new business lines such as decoking and catalyst changeout
technology for the refinery and petro-chemical industries. We fully expect that
these business lines will be significant contributors to the combined company in
the years ahead."

"For the remainder of 2009, our focus will be on gaining the necessary
approvals, completing the acquisition before the end of the third quarter, and
commencing the integration process in the second half of the year," McKim said.
"Given our acquisition expertise and track record of integration, we are
confident that our team can realize significant upside potential from the
combined company. We look forward to welcoming Eveready`s employees into the
Clean Harbors family."
