Extension of Power Purchase Agreement.

          On January 5, 2006, Zond Windsystem Partners, Ltd. Series 85-C (the
"Partnership") received the fully executed letter agreement ("Extension Letter")
dated December 28, 2005, between the Partnership and Pacific Gas and Electric
Company ("PG&E") relating to the Power Purchase Agreement For Long-Term Energy
and Capacity, dated January 17, 1985, as amended (the "Power Purchase
Agreement"). Pursuant to the Power Purchase Agreement, the Partnership is able
to sell power to PG&E from the wind turbine electric power generation facility
owned by the Partnership. The Extension Letter extended the termination date of
the Power Purchase Agreement from December 31, 2005 to January 31, 2006.

          Notwithstanding the extension, the Partnership ceased operations of
its wind turbine electric power generation facility as of January 1, 2006 and,
if the Partnership decides to recommence operations, as previously disclosed it
would do so only after March 1, 2006 and only if the Partnership is able to
obtain a further extension of the Power Purchase Agreement as well as an
extension of the Amended and Restated Windpark Easement Agreement by and between
the Partnership and Enron Wind Systems, LLC ("EWS") dated July 1, 1986, which
expired on December 31, 2005.

         A copy of the Extension Letter is attached hereto as Exhibit 10.1.

Management Agreement, dated as of January 5, 2006 (the "Management Agreement
Amendment"), which amends the Windsystem Management Agreement dated as of
November 4, 1985 (the "Management Agreement"). The Management Agreement
Amendment was effective as of December 31, 2005. Pursuant to the Management
Agreement, EWS manages the wind turbine electric power generating facility owned
by the Partnership. The Management Agreement Amendment extended
the termination date of the Management Agreement from December 31, 2005 to March
31, 2006, subject to earlier termination by either party upon ten days prior
