RALEIGH, N.C., June 9, 2008 (PRIME NEWSWIRE) -- Triangle Capital Corporation (Nasdaq:TCAP) ("Triangle" or the "Company"), a leading specialty finance company that provides customized financing solutions to lower middle market companies located throughout the United States, today announced that it closed an $8.0 million subordinated debt investment in Inland Pipe Rehabilitation Holding Company ("Inland Pipe"). The Company also received a warrant to purchase up to 2.5% of Inland Pipe's membership interests. Inland Pipe provides maintenance, inspection, and repair for piping, sewers, drains, and storm lines by utilizing several of the industry's leading technologies including pipe bursting, cured-in-place-pipe, and spiral wound piping.
