Met-Pro Corporation Announces Pension Plan Changes

Harleysville, PA, November 1 -Raymond J. De Hont, Chairman and Chief Executive Officer of Met-Pro Corporation (NYSE:MPR), announced today that the Company is freezing its current defined-benefit plans and replacing them with an enhanced defined-contribution plan for all its salaried and non-union hourly employees effective December 31, 2006. The Company had previously closed its pension plans to all employees hired after April 14, 2006 and intends to seek a similar freeze for its remaining workforce when their collective bargaining agreement is renegotiated next year.

The current changes, which were approved by the Board of Directors in the October 2006 board meeting, will result in a one time curtailment expense of approximately $0.2 million in the Company’s third quarter ended October 31, 2006, and beginning in the Company’s next fiscal year are expected to reduce the Company’s annual pension expense by approximately $0.5 million, net of increased contributions to the Company’s defined-contribution plan.

“The Company believes these changes will balance the needs of providing retirement security for our employees, while reducing financial risks and providing a more predictable cost structure for the Company,” stated De Hont. “This is a prudent decision that not only preserves pension benefits already earned, but also provides a competitive retirement plan for our employees going forward, which is in balance with the Company’s need to control costs.”
