Arsenal Announces Sale of Accella Performance Materials to Carlisle Companies

NEW YORK, October 2, 2017 - Arsenal Capital Partners (“Arsenal”), a leading private equity firm that
invests in middle-market specialty industrials and healthcare companies, announced today that it has
signed a definitive agreement to sell Accella Performance Materials (“Accella”), a leading North American
specialty polyurethane platform, to Carlisle Companies Incorporated (NYSE: CSL) (“Carlisle”) for $670
million.

Accella offers a broad range of polyurethane products and solutions across many markets and applications
globally. The company, headquartered in Maryland Heights, Missouri, has annualized revenue of
approximately $430 million and operates out of 10 manufacturing facilities and seven R&D laboratories in
the U.S., Germany, and China.

Roy Seroussi, a Principal at Arsenal, said, “Since our initial investment in 2012, Accella’s revenue and
EBITDA increased by 7x and 8x, respectively, through a focused organic growth strategy and nine strategic
acquisitions. The company has become a market leader in several rapidly growing end markets, such as
spray foam insulation, as well as roofing solutions and polyurethane truck bed liners.”
John Televantos, a Partner at Arsenal, added, “Arsenal’s investment in Accella stemmed from our extensive
experience in the polyurethane sector and focus on formulated materials that provide enhanced
performance. We have been very pleased with our partnership with Andy Harris and the management team
that helped us to transform and rapidly scale Accella. Accella is well-positioned to continue to grow under
Carlisle’s ownership.”

Andy Harris, Accella’s President and CEO, commented, “We look forward to joining the Carlisle family of
companies. Carlisle’s focus on culture, technology, markets and value creation are highly complementary
with Accella and provide significant opportunities for our customers. I would like to thank Arsenal for its
strong support of Accella’s growth and development over the past five years.”

This transaction represents the third exit in 2017 from Arsenal’s third fund, following the sales of Flowchem
to KMG Chemicals in June 2017 and Certara to EQT in August 2017. Cumulatively these three exits
represent $2.0 billion of enterprise value, a $1.5 billion increase from initial acquisition. Arsenal continues
to invest in new portfolio companies from its $1.3 billion fourth fund raised in 2016, including recent
acquisitions of PolyOne Corporation's Designed Structures and Solutions business in July 2017 and of
Cyalume Technologies in September 2017.

The transaction is subject to customary closing conditions and regulatory approvals, and is expected to be
completed in the fourth quarter of 2017.

Lazard Middle Market LLC is serving as financial advisor to Accella. DLA Piper LLP and Benesch,
Friedlander, Coplan & Aronoff LLP are serving as legal advisors to Accella.
