                               PART III--NARRATIVE
                   -------------------------------------------

State below in reasonable  detail the reasons why Forms 10-K,  20-F, 11-K, 10-Q,
10-D, N-SAR,  N-CSR, or the transition  report or portion thereof,  could not be

Geodyne  Resources,  Inc.  ("Geodyne")  serves as general  partner of 26 related
limited partnerships,  including the Geodyne Institutional/Pension Energy Income
P-1 Limited  Partnership,  Geodyne  Institutional/Pension  Energy Income Limited
Partnership P-3, Geodyne Institutional/Pension Energy Income Limited Partnership
P-4, Geodyne  Institutional/Pension  Energy Income Limited  Partnership P-5, and
Geodyne  Institutional/Pension  Energy Income Limited  Partnership  P-6. Many of
these  partnerships  sold oil and gas properties at auction during February 2007
which required the filing of Current Reports on Form 8-K with the Securities and
Exchange  Commission.  Geodyne  was  required  to  prepare  pro-forma  financial
statements  for  filing  with  these  Current  Reports.  Geodyne  has also  been
preparing for additional  property sales during May 2007 as well as planning for
the  liquidation  of the  partnerships  as of the  end of this  year.  Geodyne's
activities  related to the past and future sales of  properties,  preparation of
the Annual Reports on Form 10-K,  preparing for the  liquidation and termination
of  the  partnerships,  and  regular  management  functions  of  all  26 of  the
partnerships,  including the  registrants,  have placed a  significant  time and
workload  strain on Geodyne's  staff.  As a result,  Annual Reports on Form 10-K
cannot be timely filed without  unreasonable  effort and/or expense.  The Annual
Reports will be filed on or before April 14, 2007.
