Crawford Chief Financial Officer (615) 665-9066 PHYCOR RECEIVES $100 MILLION INVESTMENT FROM WARBURG, PINCUS Nashville, Tennessee (September 3, 1999) - PhyCor, Inc. (Nasdaq/NM:PHYC) announced today that it has received proceeds from its previously announced agreement providing for a strategic investment in the Company of up to $200 million by funds managed by E. M. Warburg, Pincus & Co., LLC (Warburg, Pincus). The agreement provides for two separate series of zero coupon convertible subordinated notes, each resulting in gross proceeds to PhyCor of $100 million. The first of these series was issued today, with the second series to be issued after receiving required shareholder approval and satisfaction of other customary conditions. Both series of notes are non-voting, have a 6.75% yield, are convertible at the option of the holder into approximately 15.0 million shares of PhyCor common stock -- an initial conversion price of $6.67, and have a 15-year maturity with an investor option to put the notes to PhyCor at the end of 10 years. The Company will use the proceeds from the first series, net of issuance costs, to repay indebtedness currently outstanding under the Company's credit facility. The proceeds from the second series are expected to fund the Company's securities repurchase program and further reductions in indebtedness outstanding under the Company's credit facility.
