Pennichuck Corporation Announces a 2.3 Percent Cash Dividend Increase
and a Four-for-Three Stock Split Payable June 1, 2005

MERRIMACK, NH (May 3, 2005) - Donald L. Correll, President and Chief Executive Officer of Pennichuck Corporation, (NASDAQ: PNNW) today announced that the company's board of directors authorized a 2.3 percent cash dividend increase above the regular March 1, 2005 quarterly cash dividend payment and also approved a stock split effected in the form of a 33 1/3 percent stock distribution. Both the increased dividend and stock distribution will be paid June 1, 2005 to shareholders of record on May 18, 2005.

Beginning with the June 1, 2005 payment, Pennichuck's quarterly dividend will increase to $.22 per share from $.215 per share ($.88 per share versus $.86 on an annualized basis) on the pre-split shares. The new quarterly cash dividend rate will be $.165 per share on the increased number of shares resulting from the stock distribution or $.66 per share annualized.

Mr. Correll said, "This action, to both split our stock and increase the dividend, is a strong indication of the confidence we have in the future. The company is making solid progress toward its key growth initiatives and remains focused on growing revenues, improving profitability, investing in infrastructure and broadening our customer base through acquisitions and new service contracts. Despite the ongoing distraction and cost of defending against the eminent domain action by the City of Nashua, the company believes that it is well-positioned to pursue new business opportunities in the year ahead. The increase in the dividend reflects our continued confidence in our long-term growth strategy and our commitment to provide consistent returns to our shareholders."
