Second Quarter Report 1997 Dear Shareholders We are pleased to report the second quarter of 1997 has been another record-breaking quarter for Triangle Bancorp. Net income for the quarter was $4.7 million, an increase of 62% over the same period in 1996. Earnings per share for the quarter were $.43, compared to $.27 for the second quarter of 1996, an increase of 62%. Earnings were positively impacted in both the 1997 and 1996 quarters by nonrecurring gains on the sale of certain branches of $1.3 million and $352,000, respectively, net of income taxes. For the six months ended June 30, 1997, earnings were $7.8 million, a 42% increase over the $5.5 million earned during the same period in 1996. Earnings per share were $.71 compared to $.51 for the same period in 1996. Excluding the sales of the branches, core earnings for the six months ended June 30, 1997 were $6.5 million, a 27% increase over the $5.1 million earned during the same period in 1996. We are extremely pleased with the growth of our net income and earning assets. In addition, earnings have been positively impacted by improvement in the operating efficiency ratio as expenses have remained relatively flat while revenues have increased significantly. In June, your Board increased the quarterly cash dividend by 10% from $.10 per share to $.11 per share for shareholders of record as of June 16, 1997. This represents an increase of 38% over the $.08 per share paid in the second quarter of 1996. In keeping with our strategic acquisition plans, during May we announced the signing of a purchase and assumption agreement to acquire ten eastern North Carolina offices with approximately $210 million in deposits and $70 million in loans from BB&T. This transaction is expected to be completed during the third quarter of this year. Also, the previously announced acquisition of Bank of Mecklenburg with approximately $270 million in assets is anticipated to be completed during the fourth quarter of the year subject to regulatory and shareholder approvals. Once these two transactions are completed, the Company will have approximately $1.5 billion in assets and operate 60 offices in North Carolina. We are also pleased to announce additional coverage for our stock as Interstate/Johnson Lane initiated coverage in early July with a "Buy" rating. In addition, beginning this month, our stock has been included in the Russell 2000 stock index, which represents an index of 2,000 small, medium and large NASDAQ companies utilized to indicate overall market performance. As a result of the financial performance of the Company and the stock market ingeneral, our stock price has increased by 64% from $13.75 to $22.50 per sharefor the quarters ended June 30, 1996 and 1997, respectively.
