                  3. Calculations. Any calculation or determination by the
         Calculation Agent pursuant hereto shall (in the absence of manifest

         obligations herein set out upon the terms and conditions hereof,
         including the following, to all of which the Company agrees:

                  (a) in acting under this Agreement, the Calculation Agent is
         acting solely as an independent expert of the Company and does not
         assume any obligation toward, or any relationship of agency or trust
         for or with, any of the holders of the Securities;

                  (b) unless otherwise specifically provided herein, any order,
         certificate, notice, request, direction or other communication from the
         Company or the Trustee made or given under any provision of this
         Agreement shall be sufficient if signed by any person who the
         Calculation Agent reasonably believes to be a duly authorized officer
         or attorney-in-fact of the Company or the Trustee, as the case may be;

                  (c) the Calculation Agent shall be obliged to perform only
         such duties as are set out specifically herein and any duties
         necessarily incidental thereto;

                  (d) the Calculation Agent, whether acting for itself or in any
         other capacity, may become the owner or pledgee of Securities with the
         same rights as it would have had if it were not acting hereunder as
         Calculation Agent; and

                  (e) the Calculation Agent shall incur no liability hereunder
         except for loss sustained by reason of its gross negligence or wilful
         misconduct.

                  6. Resignation; Removal; Successor. (a) The Calculation Agent
         may at any time resign by giving written notice to the Company of such
         intention on its part, specifying the date on which its desired
         resignation shall become effective, subject to the appointment of a
         successor Calculation Agent and acceptance of such appointment by such
         successor Calculation Agent, as hereinafter provided. The Calculation
         Agent hereunder may be removed at any time by the filing with it of an
         instrument in writing signed by or on behalf of the Company and
         specifying such removal and the date when it shall become effective.
         Such resignation or removal shall take effect upon the appointment by
         the Company, as hereinafter provided, of a successor Calculation Agent
         and the acceptance of such appointment by such successor Calculation
         Agent. In the event a successor Calculation Agent has not been
         appointed and has not accepted its duties within 90 days of the
         Calculation Agent's notice of resignation, the Calculation Agent may
         apply to any court of competent jurisdiction for the designation of a
         successor Calculation Agent.



                                                                               3

                  (b) In case at any time the Calculation Agent shall resign, or
         shall be removed, or shall become incapable of acting, or shall be
         adjudged bankrupt or insolvent, or make an assignment for the benefit
         of its creditors or consent to the appointment of a receiver or
         custodian of all or any substantial part of its property, or shall
         admit in writing its inability to pay or meet its debts as they mature,
         or if a receiver or custodian of it or all or any substantial part of
         its property shall be appointed, or if any public officer shall have
         taken charge or control of the Calculation Agent or of its property or
         affairs, for the purpose of rehabilitation, conservation or
         liquidation, a successor Calculation Agent shall be appointed by the
         Company by an instrument in writing, filed with the successor
         Calculation Agent. Upon the appointment as aforesaid of a successor
         Calculation Agent and acceptance by the latter of such appointment, the
         Calculation Agent so superseded shall cease to be Calculation Agent
         hereunder.

                  (c) Any successor Calculation Agent appointed hereunder shall
         execute, acknowledge and deliver to its predecessor, to the Company and
         to the Trustee an instrument accepting such appointment hereunder and
         agreeing to be bound by the terms hereof, and thereupon such successor
         Calculation Agent, without any further act, deed or conveyance, shall
         become vested with all the authority, rights, powers, trusts,
         immunities, duties and obligations of such predecessor with like effect
         as if originally named as Calculation Agent hereunder, and such
         predecessor, upon payment of its charges and disbursements then unpaid,
         shall thereupon become obligated to transfer, deliver and pay over, and
         such successor Calculation Agent shall be entitled to receive, all
         moneys, securities and other property on deposit with or held by such
         predecessor, as Calculation Agent hereunder.

                  (d) Any corporation into which the Calculation Agent hereunder
         may be merged or converted or any corporation with which the
         Calculation Agent may be consolidated, or any corporation resulting
         from any merger, conversion or consolidation to which the Calculation
         Agent shall be a party, or any corporation to which the Calculation
         Agent shall sell or otherwise transfer all or substantially all of the
         assets and business of the Calculation Agent shall be the successor
         Calculation Agent under this Agreement without the execution or filing
         of any paper or any further act on the part of any of the parties
         hereto.

                  7. Certain Definitions. Terms not otherwise defined herein or
         in Annex A hereto are used herein as defined in the Indenture or the
         Securities.

         Agent against any losses or liability which it may incur or sustain in
         connection with its appointment or the exercise of its powers and
         duties hereunder except such as may result from the gross negligence or
         wilful misconduct of the Calculation Agent or any of its agents or
         employees. The Calculation Agent shall incur no liability and shall be
         indemnified and held harmless by the Company for or in respect of any
         action taken or suffered to be taken in good faith by the Calculation
         Agent in reliance upon written instructions from the Company.

                                                 By: _/s/ Karen Corrigan_______
                                                     Name:  Karen Corrigan
                                                     Title: Vice President





                                ANNEX A

1. Settlement Value Securities.

                  The "Settlement Value Securities" shall mean the securities
included in the calculation of the Settlement Value from time to time and shall
initially be the common stock of Calpine Corporation, unless adjusted for
certain extraordinary corporate events as described herein.

2. Determination of the Maturity Payment Amount.

                  The Calculation Agent shall determine the amount payable on
the Stated Maturity Date for each $1,000 principal amount of YEELDS (the
"Maturity Payment Amount"). The Maturity Payment Amount shall equal (i) the
lesser of (a) the Alternative Redemption Amount and (b) $1,450 and (ii) any
accrued but unpaid coupon payments through the Stated Maturity Date.

3. Multipliers.

                  "Multiplier" shall mean, with respect to each Settlement Value
Security, the number of shares or other units (including any fractional share or
other unit expressed as a decimal) of the Settlement Value Security included in
the calculation of the Settlement Value. The initial Multiplier relating to
Calpine Corporation, initially the only Settlement Value Security, shall be 1.0.
The initial Multiplier for any other security which may subsequently become a
Settlement Value Security shall be the number of shares or other units of such
security which are to be included in the calculation of the Settlement Value at
the time the security becomes a Settlement Value Security. The Multiplier with
respect to any Settlement Value Security shall remain constant unless adjusted
for certain extraordinary corporate events as described below.

4. Adjustments to the Multipliers and the Settlement Value Securities.

                  Adjustments to a Multiplier and the Settlement Value
Securities shall be made in the circumstances described below. For purposes of
these adjustments, except as noted below, ADRs are treated like Settlement Value
Securities if a comparable adjustment to the foreign shares underlying the ADRs
is made pursuant to the terms of the depositary arrangement for the ADRs or if
holders of ADRs are entitled to receive property in respect of the underlying
foreign shares.

o    If a Settlement Value Security is subject to a stock split or reverse stock
     split, then once the split has become effective, the Multiplier relating to
     such Settlement  Value Security shall be adjusted.  The Multiplier shall be
     adjusted  to equal the product of the number of shares  outstanding  of the
     Settlement  Value  Security  after the split with  respect to each share of
     such Settlement  Value Security  immediately  prior to effectiveness of the
     split and the prior Multiplier.

o    If a  Settlement  Value  Security  is  subject  to an  extraordinary  stock
     dividend or extraordinary  stock  distribution that is given equally to all
     holders of  shares,  then once the  Settlement  Value  Security  is trading
     ex-dividend,  the  Multiplier for such  Settlement  Value Security shall be
     increased by the product of the number of shares of such

                                                                               2

     Settlement Value Security issued with respect to one share of such
     Settlement Value Security and the prior Multiplier.

o    If the issuer of a Settlement  Value  Security,  or if a  Settlement  Value
     Security is an ADR, the foreign issuer of the underlying  foreign share, is
     being  liquidated  or  dissolved  or is subject to a  proceeding  under any
     applicable  bankruptcy,  insolvency or other  similar law, such  Settlement
     Value  Security  shall  continue to be included in the  calculation  of the
     Settlement  Value so long as the  primary  exchange,  quotation  system  or
     market is reporting a market price for the Settlement Value Security.  If a
     market price,  including a price on a bulletin board service,  is no longer
     available for a Settlement Value Security, then the value of the Settlement
     Value  Security  shall  equal  zero  for so  long  as no  market  price  is
     available,  and no  attempt  shall be made to find a  replacement  stock or
     increase  the  Settlement  Value to  compensate  for the  deletion  of such
     Settlement Value Security.

o    If the issuer of a Settlement  Value  Security,  or if a  Settlement  Value
     Security is an ADR, the foreign issuer of the underlying foreign share, has
     been subject to a merger or  consolidation  and is not the surviving entity
     and holders of the Settlement  Value Security are entitled to receive cash,
     securities,  other  property or a  combination  thereof in exchange for the
     Settlement  Value  Security,  then  the  following  shall  be  included  as
     Settlement Property:

     o    To the extent cash is received,  the Settlement Property shall include
          an amount of cash equal to the  product of (1) the cash  consideration
          per share of Settlement  Value  Security,  (2) the  Multiplier for the
          Settlement   Value   Security   and  (3)  the  number  of   Securities
          outstanding,  each  determined  as of  the  time  the  holders  of the
          Settlement   Value   Security   are   entitled  to  receive  the  cash
          consideration  (the "M&A Cash Component"),  plus accrued interest.  If
          the cash  received is  denominated  in a foreign  currency,  such cash
          shall then be converted  into U.S.  dollars  using the  Official  W.M.
          Reuters Spot Closing Rate at 11:00 a.m.,  New York City time. If there
          are several quotes for the Official W.M.  Reuters Spot Closing Rate at
          that time,  the first quoted rate starting at 11:00 a.m.  shall be the
          rate used. If there is no such Official W.M. Reuters Spot Closing Rate
          for a  country's  currency  at 11:00  a.m.,  New York City  time,  the
          foreign currency-denominated cash shall be converted into U.S. dollars
          using the last available  U.S.  dollar  cross-rate  quote before 11:00
          a.m., New York City time.  Interest  shall accrue  beginning the first
          London Business Day after the day that holders of the Settlement Value
          Security receive the cash consideration until the Stated Maturity Date
          (the "M&A Cash Component Interest Accrual Period").  Interest  shall
          accrue on the M&A Cash  Component at a rate equal to the London
          Interbank Offered Rate ("LIBOR")with a term  corresponding  to the
          M&A Cash  Component Interest Accrual Period.

     o    To the extent that equity  securities  that are traded or listed on an
          exchange,  quotation system or market are received,  once the exchange
          for the new securities  has become  effective,  the former  Settlement
          Value Security shall be removed from the calculation of the Settlement
          Value and the  Settlement  Property will include a number of shares of
          the new security per outstanding  Security equal to the Multiplier for
          the new security as a new Settlement  Value  Security.  The Multiplier
          for the new  Settlement  Value Security shall equal the product of the
          last value of


                                                                               3

          the  Multiplier of the original Settlement Value Security and the
          number of securities of the new Settlement Value Security exchanged
          with respect to one share of the original Settlement Value Security.

     o    To the extent that equity  securities that are not traded or listed on
          an exchange,  quotation  system or market or non-equity  securities or
          other property (other than cash) is received,  the  Calculation  Agent
          shall  determine  the "Fair Market  Value" of the  securities or other
          property  received per share of Settlement Value Security based on the
          Average  Execution  Price.  The  Settlement  Property shall include an
          amount of cash equal to the product of (1) the Fair  Market  Value per
          share  of  Settlement  Value  Security,  (2)  the  Multiplier  for the
          Settlement Value Security and (3) the number of Securities outstanding
          (the  "M&A  Sale  Component").   The  Multiplier  and  the  number  of
          Securities  outstanding  will be  determined as of the time holders of
          the  Settlement  Value Security are entitled to receive the securities
          or other  property.  The Settlement  Value shall also include  accrued
          interest on the M&A Sale  Component.  Interest shall accrue  beginning
          the first  London  Business  Day after  the day that an  affiliate  of
          Holdings  sells  the  securities  or  other  property  used  to  hedge
          Holdings'  obligations  under the Securities until the Stated Maturity
          Date (the "M&A Sale  Component  Interest  Accrual  Period").  Interest
          shall accrue at a rate equal to LIBOR with a term corresponding to the
          M&A Sale Component Interest Accrual Period.

o    If all of the  shares of a  Settlement  Value  Security  of an  issuer  are
     converted into or exchanged for the same or a different number of shares of
     any class or  classes of common  stock  other  than such  Settlement  Value
     Security,   whether  by   capital   reorganization,   recapitalization   or
     reclassification  or  otherwise,  then,  once  the  conversion  has  become
     effective,  the former  Settlement Value Security shall be removed from the
     calculation  of the  Settlement  Value  and the  Settlement  Property  will
     include a number of shares of the new common stock per outstanding Security
     equal to the Multiplier for the new common stock as a new Settlement  Value
     Security. The Multiplier for each new Settlement Value Security shall equal
     the product of the last value of the Multiplier of the original  Settlement
     Value  Security  and the  number  of  shares  of the new  Settlement  Value
     Security issued with respect to one share of the original  Settlement Value
     Security.

o    If the issuer of a Settlement  Value  Security,  or if a  Settlement  Value
     Security is an ADR, the issuer of the underlying  foreign share,  issues to
     all of its  shareholders  common stock or another  equity  security that is
     traded or listed on an  exchange,  quotation  system or market of an issuer
     other than itself,  then the Settlement  Property shall include a number of
     shares  of the new  common  stock  per  outstanding  Security  equal to the
     Multiplier  for the new  common  stock or other  equity  security  as a new
     Settlement  Value  Security.  The Multiplier  for the new Settlement  Value
     Security shall equal the product of the last value of the  Multiplier  with
     respect to the original  Settlement Value Security and the number of shares
     of the new  Settlement  Value  Security  with  respect  to one share of the
     original Settlement Value Security.

o    If an ADR is no longer  listed or  admitted  to trading on a United  States
     securities exchange registered under the Securities Exchange Act of 1934 or
     is no longer a security  quoted on The Nasdaq  Stock  Market,  then the ADR
     shall be removed from the calculation of the Settlement  Value, the foreign
     share  underlying  the ADR shall be deemed to be a new common stock and the


                                                                               4


     Settlement  Property  shall  include a number of shares of new common stock
     per  outstanding  Security equal to the Multiplier for the new common stock
     as a new Settlement  Value  Security.  The initial  Multiplier for that new
     Settlement  Value Security shall equal the product of the last value of the
     Multiplier  with respect to the  original ADR and the number of  underlying
     foreign shares represented by a single such ADR.

o    If a Settlement Value Security is subject to an  extraordinary  dividend or
     an extraordinary  distribution,  including upon liquidation or dissolution,
     of cash,  equity  securities  that are not traded or listed on an exchange,
     quotation system or market,  non-equity securities or other property of any
     kind which is  received  equally by all  holders of such  Settlement  Value
     Security, then the Settlement Property shall include the following:

     o    To the extent cash is entitled to be received, the Settlement Property
          shall  include  on each day after the time that the  Settlement  Value
          Security trades  ex-dividend until the date the cash  consideration is
          entitled to be received,  the present value of the cash to be received
          per share of Settlement  Value  Security  multiplied by the Multiplier
          for the  Settlement  Value  Security  on such day and by the number of
          Securities  outstanding  on such day,  discounted  at a rate  equal to
          LIBOR,  with a term beginning that day and ending on the date that the
          cash  is  entitled  to  be  received  (the  "PV   Extraordinary   Cash
          Component").   When  the  cash  consideration  is  received,   the  PV
          Extraordinary  Cash  Component  shall be deleted  from the  Settlement
          Value and the  Settlement  Property  shall  include  an amount of cash
          equal  to the  product  of (1) the  cash  consideration  per  share of
          Settlement Value Security, (2) the Multiplier for the Settlement Value
          Security and (3) the number of Securities outstanding, each determined
          as of the  time the  holders  of the  Settlement  Value  Security  are
          entitled to receive the cash  consideration (the  "Extraordinary  Cash
          Component"), plus accrued interest. If the cash consideration received
          or entitled to be received is denominated in a foreign currency,  such
          cash or the present  value of such cash,  as the case may be, shall be
          converted  into U.S.  dollars  using the  Official  W.M.  Reuters Spot
          Closing Rate at 11:00 a.m.,  New York City time.  If there are several
          quotes for the Official  W.M.  Reuters Spot Closing Rate at that time,
          the first quoted rate  starting at 11:00 a.m.  shall be the rate used.
          If there is no such  Official  W.M.  Reuters  Spot  Closing Rate for a
          country's  currency  at 11:00  a.m.,  New York City time,  the foreign
          currency-denominated  cash shall be converted into U.S.  dollars using
          the last available U.S. dollar cross-rate quote before 11:00 a.m., New
          York  City  time.  Interest  shall  accrue on the  Extraordinary  Cash
          Component  beginning the first London  Business Day after the day that
          holders of the  Settlement  Value Security are entitled to receive the
          Extraordinary  Cash  Component  until the  Stated  Maturity  Date (the
          "Extraordinary  Cash Component  Interest  Accrual  Period").  Interest
          shall accrue at a rate equal to LIBOR with a term corresponding to the
          Extraordinary Cash Component Interest Accrual Period.

     o    To the extent that equity  securities that are not traded or listed on
          an exchange,  quotation  system or market or non-equity  securities or
          other property (other than cash) is received,  the  Calculation  Agent
          shall  determine  the Fair  Market  Value of the  securities  or other
          property  received per share of Settlement Value Security based on the
          Average  Execution Price and the Settlement  Property shall include an


                                                                               5

          amount of cash equal to the product of (1) the Fair  Market  Value per
          share  of  Settlement  Value  Security  , (2) the  Multiplier  for the
          Settlement Value Security and (3) the number of Securities outstanding
          (the "Extraordinary Sale Component"). The Multiplier and the number of
          Securities  outstanding  will be determined as of the time the holders
          of  the  Settlement   Value  Security  are  entitled  to  receive  the
          securities  or other  property.  The  Settlement  Property  shall also
          include accrued interest on the Extraordinary Sale Component. Interest
          shall accrue  beginning  the first  London  Business Day after the day
          that an affiliate of Holdings  sells the  securities or other property
          used to hedge  Holdings'  obligations  under the Securities  until the
          Stated  Maturity  Date (the  "Extraordinary  Sale  Component  Interest
          Accrual Period").  Interest shall accrue at a rate equal to LIBOR with
          a term  corresponding  to the  Extraordinary  Sale Component  Interest
          Accrual Period.

o    If similar  corporate  events occur with respect to the issuer of an equity
     security other than a Settlement Value Security, adjustments similar to the
     above will be made for that  equity  security.  In  addition,  if any other
     corporate  events occur with  respect to the issuer of a  Settlement  Value
     Security,  adjustments  will be made to reflect the  economic  substance of
     such  events.

The payment of an ordinary  cash  dividend  by an issuer of a  Settlement  Value
Security,  or if a Settlement  Value  Security is an ADR, by a foreign issuer of
the underlying foreign share, from current income or retained earnings shall not
result in an adjustment to the Multiplier.

No adjustments of any Multiplier of a Settlement Value Security shall be
required unless the adjustment would result in a change of at least .1% (.001)
in the Multiplier then in effect. Adjustments which result in a change of less
than .1% (.001) shall be carried forward and included in the next adjustment, if
any. The Multiplier resulting from any of the adjustments specified above shall
be rounded at the Calculation Agent's discretion.
