     - Orders for the North American Industrial business increased 13 percent
       over the same month last year.
     - Rest-of-World Industrial orders increased 23 percent.

Industrial markets remain strong in both North America and Rest-of-World, including MRO, construction, mining, oil and gas, power generation, and semiconductor.

     - Parker Aerospace reported an 18 percent increase in orders on a rolling
       12-month basis.  Commercial OEM and MRO markets remain strong.
     - In the Climate and Industrial Controls segment, order rates increased
       19 percent compared to last year, lead by heavy duty truck, commercial
       refrigeration, and air conditioning.

Orders provide near-term perspective on the company's outlook, particularly when viewed in the context of prior and future monthly order rates. However, orders are not in themselves an indication of future performance. All comparisons are at constant currency exchange rates, with the prior year restated to the current-year rates. All exclude acquisitions until they can be reflected in both the numerator and denominator. Aerospace comparisons are rolling 12-month average computations to mitigate volatility within monthly figures.
