                                  CERTIFICATION
I, Edward E. Cohen, certify that:

1. I have reviewed this annual report on Form 10-K for the year ended December
31, 2004 of Atlas Pipeline Partners, LP;

2. Based on my knowledge, this report does not contain any untrue statement of a
material fact or omit to state a material fact necessary to make the statements
made, in light of the circumstances under which such statements were made, not
misleading with respect to the period covered by this report;

3. Based on my knowledge, the financial statements, and other financial
information included in this report, fairly present in all material respects the
financial condition, results of operations and cash flows of the registrant as
of, and for, the periods presented in this report;

4. The registrant's other certifying officer(s) and I are responsible for
establishing and maintaining disclosure controls and procedures (as defined in
Exchange Act Rules 13a-15(e) and 15d-15(e)) and internal control over Financial
Reporting (as defined in Exchange Act Rules under 13a-15(f) and 15d-15(f)) for
the registrant and have:

   (a) Designed such disclosure controls and procedures, or caused such
       disclosure controls and procedures to be designed under our supervision,
       to ensure that material information relating to the registrant, including
       its consolidated subsidiaries, is made known to us by others within those
       entities, particularly during the period in which this report is being
       prepared;

   (b) Designed such internal control over financial reporting, or caused such
       internal control over financial reporting to be designed under our
       supervision, to provide reasonable assurance regarding the reliability of
       financial reporting and the preparation of financial statements for
       external purposes in accordance with generally accepted accounting
       principles;

   (c) Evaluated the effectiveness of the registrant's disclosure controls and
       procedures and presented in this report our conclusions about the
       effectiveness of the disclosure controls and procedures, as of the end of
       the period covered by this report based on such evaluation; and

   (d) Disclosed in this report any change in the registrant's internal control
       over financial reporting that occurred during the registrant's most
       recent fiscal quarter (the registrant's fourth fiscal quarter in the case
       of an annual report) that has materially affected, or is reasonably
       likely to materially affect, the registrant's internal control over
       financial reporting; and

5. The registrant's other certifying officer(s) and I have disclosed, based on
our most recent evaluation of internal control over financial reporting, to the
registrant's auditors and the audit committee of the registrant's board of
directors (or persons performing the equivalent functions):

   (a) All significant deficiencies and material weaknesses in the design or
       operation of internal control over financial reporting which are
       reasonably likely to adversely affect the registrant's ability to record,
       process, summarize and report financial information; and

   (b) Any fraud, whether or not material, that involves management or other
       employees who have a significant role in the registrant's internal
       control over financial reporting.
