       Inergy Signs Definitive Agreement to Acquire Graeber Brothers, Inc.
                              ********************
                         Increases Fiscal 2006 Guidance

         Kansas City, MO (October 5, 2005) - Inergy, L.P. (Nasdaq:NRGY)
announced today that it has signed a definitive agreement to purchase the assets
of Graeber Brothers, Inc., located in northern Mississippi. Graeber delivers
retail propane to approximately 14,000 customers from six retail locations which
are contiguous with our recently closed acquisition of Dowdle Gas, Inc. This
transaction represents Inergy's 52nd acquisition since its founding in 1996. The
assets to be purchased will be operated under the existing trade name and the
transaction is expected to be immediately accretive to Inergy unitholders on a
distributable cash flow per unit basis.

         "The Graeber business is a very well-run propane operation in a good
market with a reputation for customer service and quality," said John Sherman,
President and CEO of Inergy. "We are pleased to further build on our presence in
the southeast, and we welcome the Graeber employees to the Inergy team as we
continue to grow cash earnings on behalf of our unitholders."

         With the closing of the Graeber transaction and the previously
announced acquisitions of Atlas Gas Products, Inc. and Dowdle Gas, Inc., Inergy
will complete the approximate $160 million outstanding in letters of intent to
acquire additional propane assets as disclosed.

         Inergy, L.P. also announces updated guidance for the full fiscal year
ended September 30, 2006, giving effect to the acquisitions closed to date,
including the acquisition of Graeber which we expect to close during the month
of October 2005. Inergy expects to generate EBITDA of $169 to $177 million in
fiscal year 2006. In addition, Inergy expects to deliver approximately 415 to
435 million retail gallons of propane and generate $416 to $422 million of total
gross profit. Below is a table reconciling this anticipated EBITDA to net
income:
