Pennichuck Corporation Announces PUC Approval of Merger Transaction

  Pennichuck Corporation (NASDAQ: PNNW) today announced that the New Hampshire Public Utilities Commission ("NHPUC") issued its order approving Pennichuck's acquisition by the City of Nashua, New Hampshire (the "City") pursuant to the terms of an Agreement and Plan of Merger dated November 10, 2010 ("Merger Agreement"). The order found that the settlement agreement previously entered into by substantially all of the parties in the case is in the public interest pursuant to special legislation that allows the City to acquire the stock of Pennichuck and the New Hampshire Eminent Domain Statute (RSA Chapter 38). The NHPUC specifically approved the conditions set forth in the settlement agreement and did not add any new conditions to its approval.

The NHPUC's order is subject to appeal for a 30-day period following its issuance; thereafter, if no appeal is filed, it becomes final. Under the terms of the Merger Agreement, the City, in effect, has 90 days after the NHPUC order becomes final to complete the financing. Based on the timing of the issuance of the order, the merger is expected to be completed in the first quarter of 2012.

Commenting on Pennichuck's planned acquisition by the City of Nashua, Duane C. Montopoli, Pennichuck's President and Chief Executive Officer, said, "I am pleased that we were able to obtain a favorable ruling approving our settlement agreement. While the order is subject to a 30-day appeal period, we anticipate that Nashua will complete its bond issue as soon as practicable, allowing the transaction to close early in 2012."
