Sentinel acquires Trinity Consultants in management buyout

Investment In Nation's Premier Air Quality Services Firm

NEW YORK, December 3, 2007 - Sentinel Capital Partners, a private equity firm that invests in promising, smaller middle market companies, today announced the acquisition of Trinity Consultants, Inc., the nation's leading provider of air quality consulting and compliance services. Sentinel partnered with Trinity's management and employees in the transaction.

"Trinity is the premier player in its market and faces substantial opportunities given the increasing global focus on the environment, including greenhouse gas emissions and other air quality concerns," said Eric Bommer, a partner at Sentinel. "This investment fits well with Sentinel's core strategy of investing in niche market leaders with promising growth prospects."

Trinity offers a full range of air quality compliance services and has specific expertise in the energy, manufacturing, industrial, and utilities sectors. Trinity helps its clients comply with federal, state, and local air quality regulations. It also provides complementary products and services, such as educational courses, dispersion modeling, and greenhouse gas emissions management practices. Headquartered in Dallas, Texas, Trinity has more than 270 employees in 24 strategically located offices.

"Trinity has enjoyed great success and growth over the last 30 years, and all of Trinity's management and employees are excited about this new stage in our company's development," said John E. (Jay) Hofmann, CEO of Trinity. "We firmly believe that Sentinel is the right partner for Trinity; they have already succeeded in creating a strong rapport with management and our employees."

"At Sentinel, forming strong partnerships with management and employees is an important component of our investment philosophy," said John McCormack, a senior partner at Sentinel. "We are pleased by the strong support and participation by Trinity management and employees in the transaction. We look forward to working with Trinity's highly professional and talented employees to drive continued success."

The Trinity transaction is the latest in a highly productive period for Sentinel in terms of both new investments and realizations. To date in 2007, Sentinel has closed seven new investments, five since the turmoil in worldwide financial markets began in July. These investments include Midwest Wholesale Hardware, a wholesaler of architecturally specified commercial door hardware; Trussbilt, an 80 year-old manufacturer of steel security products for the detention and corrections market; Inscape Publishing, a leading provider of corporate training solutions for employee assessment and development; Vintage Parts, the leading independent distributor of slow moving and inactive original OEM replacement parts; ReachOut Healthcare America, the leading provider of mobile dental services to underserved children; Spinrite, one of North America's leading producers and marketers of consumer craft yarn for the needlepoint market; and Trinity.

For Sentinel, 2007 has also been a productive year for realizations. To date, Sentinel has sold three portfolio businesses, including Fasloc, the leading North American manufacturer of specialty safety products used for underground coal mine roof support; Metro Dentalcare, a leading regional multi-specialty dental group; and Nivel, North America's largest independent, value-added distributor of golf car aftermarket replacement parts and accessories.
