Purchased Equity Interests and the AHD GP Contribution (the &#147;<U>Proposed Allocation</U>&#148;) for purposes of Section&nbsp;1060 of the Code. If within thirty (30)&nbsp;days after Atlas&#146;s receipt of the Proposed Allocation, Atlas consents
in writing to the Proposed Allocation, then the Proposed Allocation shall become the Final Allocation, as defined below. In the event that Atlas does not consent in writing within such thirty (30)&nbsp;day period, AHD and Atlas shall negotiate in
good faith to resolve the dispute. If AHD and Atlas fail to agree on such allocation within thirty (30)&nbsp;days, such allocation shall be determined, within a reasonable time, by an independent, nationally recognized accounting firm mutually

to be timely filed, Internal Revenue Service Form 8594 (or any comparable form under state or local Tax Law) and any required attachment thereto in accordance with the Final Allocation. Except as otherwise required pursuant to a

these Michigan wells. Without these Michigan wells, a full restructuring of the offering would have to have been initiated. In addition, significant amendments to the offering memorandum would be necessary. Given the time constraints, we determined
to withdraw the offering. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px"><FONT STYLE="font-family:Times New Roman" SIZE="2">If you want any assistance in discussing our partnership business with clients, we are available to assist you.

these assets and the overwhelming majority of our employees working in financial and administrative divisions will join Atlas Pipeline Holdings.&nbsp;As Chairman of both companies, I will welcome you to an Atlas Pipeline Holdings, whose corporate

Pipeline Holdings, we expect that you will be part of an expanding and prospering company whose future success we hope will be even greater than we&#146;ve accomplished to date at Atlas Energy. Those of you going with Chevron should know that
through this sale, we will be bringing into the Marcellus Shale one of the world&#146;s largest corporations, an energy company second to none in its skills and dedication to excellence, and, in my opinion, very similar to Atlas Energy in its desire

2010, the day prior to the announcement of the Chevron transaction, 0.525 of an AHD unit had a value of $5.09. Assuming that each AHD unit is valued at that same closing price, each ATLS share would receive $43.34 in consideration in the Chevron
acquisition, consisting of $38.25 in cash and $5.09 of AHD units. As noted above, however, the value of the AHD units per ATLS share at the time of the closing of the Chevron acquisition may be different than the last closing price of an AHD unit
prior to the announcement of the transaction.</B> </FONT></P>
