                      RAYOVAC TO ACQUIRE UNITED INDUSTRIES

 Transaction Diversifies Company into Large High-Growth Markets: Lawn & Garden,
              Specialty Pet Supplies and Household Insect Control

ATLANTA, Jan. 4, 2005 - Rayovac Corp. (NYSE:ROV), a global consumer products
company with a diverse portfolio of world-class brands, announced today that it
has reached an agreement to acquire United Industries Corporation. The
transaction calls for Rayovac to issue 13.75 million shares of its common
stock, along with additional consideration of $70 million in cash, to United
Industries' current shareholders, for a total value of approximately $1.2
billion including the assumption of approximately $880 million of United
Industries debt and a cash tax benefit of $140 million. This acquisition
extends Rayovac's household products offerings into the large and growing lawn
and garden and specialty pet supply categories, while leveraging the company's
operational expertise and existing relationships with global retailers.

Privately held United Industries, based in St. Louis, is a leading manufacturer
and marketer of consumer products for lawn and garden care and household insect
control, operating as Spectrum Brands in the United States and NuGro in Canada.
United also holds a leading position in the fragmented but fast-growing U.S.
pet supply market, manufacturing and marketing premium branded specialty pet
supplies through its United Pet Group. Among United's brands are
Spectracide(R), Vigoro(R), Sta-Green(R), Schultz(TM) and C.I.L(R) in the lawn
and garden market; Hot Shot(R), Cutter(R) and Repel(R) in the household insect
control market; and Marineland(R), Perfecto(R) and Eight in One(R) among pet
supply products. United estimates total 2004 pro forma sales of $950 million
(assumes acquisitions made during 2004 were part of United's results for the
entire twelve months) to customers including The Home Depot, Lowe's, Wal-Mart,
PETCO and PETsMART.

"Rayovac's publicly stated goal has been to grow through acquisitions that
diversify and increase our revenue base while leveraging our global
merchandising and distribution capabilities. United Industries is just such an
acquisition," said David A. Jones, Rayovac's chairman and chief executive
officer. "Upon closing, we will have a significant presence in several new
consumer products markets -- large growth categories where we can capitalize on
our strengths with major retailers to leverage the full potential of the
powerful combined enterprise."

The company noted that the United transaction will significantly diversify
Rayovac's revenue base. It is expected that after closing, worldwide battery
sales will represent approximately 40 percent of total combined pro forma
revenue versus the current level of approximately 67 percent.

Added Jones: "This is a truly transforming transaction for Rayovac,
representing a major step forward toward our goal of achieving annual revenues
of $3 billion."

 "We are extremely pleased to join a company that clearly believes in our
brands, our markets and our merchandising strategy," said United Industries
Chief Executive Officer Robert L. Caulk, who is expected to join Rayovac's
senior management team. "We share Rayovac's belief that our products will
flourish as part of a larger company with an integrated global manufacturing,
distribution and information services platform and a more significant
relationship with our customers."

"The combination of Rayovac and United Industries offers a compelling value
proposition," said Thomas H. Lee Partners Co-President Scott Schoen. "United's
strong brands and history of operational excellence will be further
strengthened in combination with Rayovac's global manufacturing, distribution,
supply chain and IT infrastructure. The Rayovac management team has established
a track record of successfully integrating acquired businesses while
maintaining marketplace momentum. Our ongoing ownership stake is a tangible
demonstration of our confidence in the future success of the combined
enterprise."

Rayovac's current expectations are that the transaction will be slightly
accretive to earnings before synergies in year one. The company's initial
expectations anticipate gross synergies approximating $70 to $75 million
(before one-time costs) to be realized over a three year period. Anticipated
cost savings include efficiencies to be gained through rationalization of
manufacturing, global purchasing, distribution and information technology. In
addition to these cost savings, Rayovac has identified a number of
opportunities to drive revenue growth through cross-selling and coordination of
sales and marketing efforts.


Transaction Details

The transaction is subject to approval under the Hart-Scott-Rodino Anti-trust
Improvements Act and other customary closing conditions. Rayovac plans to enter
into a new senior secured credit facility and issue senior subordinated notes
in connection with the acquisition. Existing United Industries debt of
approximately $900 million will be redeemed or replaced by the new credit
facility. The transaction has been approved by United's shareholders. The
transaction is expected to close in February.

United is 83 percent owned (on a fully diluted basis) by the Thomas H. Lee
Equity Fund IV, a private equity fund managed by Thomas H. Lee Partners and
affiliates (THL). It is anticipated that following the transaction THL will
hold an ownership position in Rayovac of approximately 25 percent. The shares
of Rayovac common stock received by United shareholders in the transaction will
be issued pursuant to an exemption from registration under the federal
securities laws. Rayovac has agreed to file a shelf registration within nine
months following closing to allow for the sale of such shares. As part of the
transaction, the shares issued to United shareholders will be subject to a
lockup agreement expiring one year after the closing date relative to 50
percent of the shares and 18 months after the closing date for the remaining 50
percent. In addition, two new Class II seats will be added to Rayovac's current
eight-person board of directors, to be filled by candidates selected by the THL
shareholders.

Rayovac and THL were previously partners when THL invested in Rayovac
Corporation in 1996. THL maintained a significant interest in Rayovac until
September 2002. David Jones, Rayovac chairman and chief executive officer, was
a board member of United Industries from 1999 to 2003. Rayovac noted that an
independent committee of its board was established to evaluate, negotiate and
approve the terms of the transaction. Citigroup Global Markets Inc. served as
advisors to the independent committee of the Rayovac board of directors.
Merrill Lynch & Co. served as financial advisor to Rayovac Corporation, and
Goldman Sachs & Co. advised United Industries.
