ITEM 2.03 -- CREATION OF A DIRECT FINANCIAL OBLIGATION OR AN OBLIGATION UNDER AN
             OFF-BALANCE SHEET ARRANGEMENT OF A REGISTRANT

     On October 14, 2005,  CCFC Preferred  Holdings,  LLC (the "Issuer")  issued
300,000  Redeemable  Preferred  Shares  (the  "Preferred  Shares"),  each with a
paid-up  value of  $1,000.  The  Issuer is an  indirect  subsidiary  of  Calpine
Corporation  ("Calpine") and an indirect parent of Calpine  Construction Finance
Company,  L.P. ("CCFC").  The Preferred Shares were sold to accredited investors
and qualified  institutional  buyers in a private placement in the United States
under Section 4(2) and  Regulation D under the  Securities  Act of 1933.  Morgan
Stanley  & Co.  Incorporated  acted as  placement  agent for the  offering.  Net
proceeds from the sale of the Preferred  Shares were  distributed to Calpine for
use in accordance with Calpine's existing bond indentures.

     The Preferred  Shares  initially accrue dividends at a rate per annum equal
to the six-month U.S. Dollar LIBOR plus a margin of 950 basis points except that
upon the  occurrence  and  during  the  continuance  of  certain  voting  rights
triggering  events (as described  below),  the rate per annum for dividends will
increase by 200 basis points above the then-applicable margin. Dividends will be
payable  in cash  semi-annually  in  arrears  each  February  26 and  August 26,
beginning on February 26, 2006.

     Voting rights triggering events include, among other things, the failure of
the Issuer to declare and pay  dividends  when due or to satisfy  any  mandatory
redemption or repurchase requirements;  the occurrence of a default under CCFC's
term loan agreement or the indenture  governing CCFC's second priority  floating
rate notes  (together,  the "CCFC Financing  Documents");  the breach of certain
other  covenants or  undertakings  with  respect to the  Preferred  Shares;  and
certain   bankruptcy-related   events  in   relation   to  the  Issuer  and  its
subsidiaries. In addition, upon the occurrence of a voting rights trigger event,
the  holders of the  Preferred  Shares will have the right to elect the board of
directors of the Issuer.

     The Issuer may redeem any of the Preferred  Shares beginning on October 15,
2008 at an  initial  redemption  price of 100% of  paid-up  value plus a premium
equal to 5%. The Issuer will be  required to redeem all of the then  outstanding
Preferred  Shares on October 14, 2011,  at their  paid-up  value,  together with
accrued  and unpaid  dividends  to such date.  Additionally,  the Issuer will be
required to redeem or  repurchase  Preferred  Shares (i) upon the  occurrence of
certain  change of control  events with respect to the Issuer  and/or its direct
and indirect parents and/or subsidiaries,  and (ii) with the proceeds of certain
assets sales,  debt  issuances,  and equity  issuances,  in each case (x) by the
Issuer  and/or  its  direct  and  indirect  subsidiaries  and (y) to the  extent
permitted by, and after compliance with all applicable requirements of, the CCFC
Financing Documents.

     The terms of the Preferred  Shares require the Issuer and its  subsidiaries
to comply with all of its  obligations  under the CCFC Financing  Documents,  as
well as certain additional covenants.

ITEM 8.01 --  OTHER EVENTS

     On October 6, 2005, in connection with the sale of its Ontelaunee  facility
and  in  accordance  with  the  instruments  governing  its  indebtedness,  CCFC
commenced  simultaneously (i) an offer to purchase a portion of the indebtedness
outstanding  under its Credit and  Guarantee  Agreement,  dated as of August 23,
2003, as amended (the "Term Loans") with the net proceeds of the Ontelaunee sale
and (ii) a tender offer for a portion of its outstanding  Second Priority Senior
Secured  Floating Rate Notes due 2011 (the "Notes") with the net proceeds of the
Ontelaunee sale remaining after the payment for the Term Loans (if any) tendered
pursuant to the offer to purchase. The expiration date for the offer to purchase
Term Loans is October 28,  2005,  and the  expiration  date for the Notes tender
offer is November 4, 2005, in each case unless  extended or earlier  terminated.
Term Loans and Notes tendered  pursuant to the applicable offer may be withdrawn
at any time prior to the applicable expiration date. The purchase price for Term
Loans and Notes validly tendered (and not validly  withdrawn) on or prior to the
applicable  expiration date, and that are accepted for purchase  pursuant to the
terms and  conditions  of the  applicable  offer,  in each case will be par plus
accrued  interest to and including the  applicable  purchase  date. The purchase
date for the Term Loans and Notes  accepted for purchase  will be not later than
the third  business day following the expiration  date of the applicable  offer.
The offers are subject to customary  conditions,  including,  in the case of the
Notes,  the  availability of net proceeds from the Ontelaunee sale to repurchase
Notes pursuant to the tender offer after repayment of Term Loans.

     CCFC does not make any recommendation as to whether or not holders of Notes
or Term Loans should  tender  their Notes or Term Loans  pursuant to the offers.
Holders must make their own decision as to whether to tender their Notes or Term
Loans, and if tendering,  the principal amount to tender. The information herein
is  not an  offer  to  purchase  or a  solicitation  of an  offer  to  sell  any
securities.
