(c)	The accountant’s statement or other exhibit required by Rule 12b-25(c) has been attached if applicable.

PART III — NARRATIVE

State below in reasonable detail 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 filed within the prescribed time period.

We determined that we were unable to file our Form 10-Q for the quarter ended June 30, 2012 by the August 14, 2012 due date or by the August 19, 2012 extension date.

We are not able to file a timely Form 10-Q for the quarter ended June 30, 2012, because we have not completed required financial statements for previous reporting periods.  In November 2005, we determined that our previously issued financial statements for the year ended December 31, 2004, and for the quarter ended March 31, 2005, should no longer be relied upon.  More information regarding the 2004 restatement and our initial efforts to file our comprehensive 2005 10-K including quarterly financial information can be found in our Current Report on Form 8-K filed with the SEC on November 15, 2005 and our Form 12b-25’s filed with the SEC on April 3, 2006 and August 15, 2006.

As disclosed and discussed further in the current report on Form 8-K filed October 26, 2006, in an effort to complete the 2005 annual financial statements on a timely basis, including the restatement of prior years financial statements, the managing general partner engaged new auditors for our partnership and for 14 of the 25 other partnerships then subject to SEC reporting requirements.

The managing general partner continues to evaluate alternative courses of action aimed at satisfying reporting requirements for all sponsored partnerships in the most expeditious manner possible.  At this time we are not able to estimate when we will file all delinquent reports described in Part IV (2) below.

Because of the matters discussed above, management expects to have material weaknesses in its internal controls over financial reporting.
