   3.3    Certain  Restrictions  on  Sales  by  Calpine of Equity Securities and
Assets of CMSC.

          (a) Calpine and each of the Calpine  Transaction Parties hereby agrees
that it shall not, and shall cause its Affiliates not to, directly or indirectly
(through the sale of Equity  Securities  in an Affiliate  or  otherwise),  sell,
assign, transfer, convey, pledge, mortgage, hypothecate or otherwise encumber or

3.3.  If  Calpine,  any of the  Calpine  Transaction  Parties,  or any of  their
Affiliates  wishes to  Transfer  any such Assets or Equity  Securities,  Calpine
shall first  deliver to Bear Stearns a letter (the "Initial  Notice")  signed by
Calpine (and any such Calpine  Transaction  Party or Affiliate,  if  applicable)
setting forth the Equity Securities and/or Assets proposed to be Transferred and

          (b) Upon receipt of an Initial Notice, Bear Stearns and its Affiliates
shall  have  forty  five (45) days (the  "Initial  Period")  to submit a binding
letter (the "Offer Notice")  signed by Bear Stearns (and any such Affiliate,  if
applicable)  setting  forth (A) a proposed  purchase  price with  respect to the
Equity Securities and/or Assets proposed to be Transferred and (B) Bear Stearns'
(or such Affiliate's) offer (irrevocable by its terms for five (5) Business Days


                                       18

Calpine  Transaction  Party or any of their  Affiliates  the  Equity  Securities
and/or  Assets  described  in the Initial  Notice,  on the terms and  conditions
described  in the  Initial  Notice and for the  purchase  price set forth in the
Offer Notice (an "Offer").  If an Offer Notice is delivered  prior to the end of
the Initial Period, the Initial Period shall end on the date of delivery of such
Offer Notice and the Offer Period shall  commence on such date.  If neither Bear
Stearns nor any of its Affiliates delivers an Offer Notice to Calpine within the
Initial Period, Calpine or its Affiliate may, during the period beginning on the
forty-sixth  (46th) day  following  the  receipt of the  Initial  Notice by Bear

contained in the Initial Notice;  provided that if a Third Party  transferee has
accepted  such offer,  Calpine  shall have  completed  such  Transfer  within an
additional  one hundred  eighty  (180) days from the end of such ninety (90) day
period; and provided,  further,  that, with respect to any such Transfer that is
not completed within the time periods set forth in this Section 3.3(b),  Calpine
shall not complete any such Transfer without again complying with each provision
of this Section 3.3, as applicable.

          (c) Upon receipt of an Offer Notice,  Calpine and its Affiliates shall
have the option to sell the Equity  Securities  and/or  Assets  described in the
Initial Notice to Bear Stearns (or its Affiliate, as applicable) at the purchase
price and upon the terms and  conditions  specified in the Offer.  If Calpine or
any of its Affiliates  desires to exercise the option set forth in the preceding
sentence,  it shall deliver a notice (an  "Election  Notice") to Bear Stearns at
any time during the Offer  Period,  which  Election  Notice  shall  specify that
Calpine or any of its  Affiliates  has elected to exercise  its option to accept
the Offer and sell the Equity  Securities and/or Assets described in the Initial
Notice to Bear Stearns (or its Affiliate,  as applicable) on the terms set forth
in the Offer.  If Calpine or any of its Affiliates  delivers an Election  Notice
during the Offer Period,  then Bear Stearns (or its  Affiliates,  as applicable)
shall be obligated to purchase and Calpine (or such  Affiliate,  as  applicable)
shall be obligated to sell, the Equity Securities and/or Assets described in the
Initial  Notice at the  purchase  price and on the  other  terms and  conditions
indicated in the Offer.  The closing of such  purchase and sale shall occur on a
closing  date  selected  by Bear  Stearns  or  such  Affiliate,  as  applicable;
provided,  however,  that such closing date shall be not less than ten (10) days
nor more than ninety (90) days following the date of the Election Notice, unless
more time is required to obtain any applicable regulatory or other approvals. If
neither  Calpine nor any of its Affiliates  delivers an Election  Notice to Bear
Stearns (or its  Affiliate,  as applicable)  within the Offer Period,  the Offer
shall  automatically  expire at the end of the Offer  Period  and  neither  Bear
Stearns nor any of its  Affiliates  shall have any  obligation  to purchase  the
Equity Securities and/or Assets described in the Initial Notice.

          (d) If Bear Stearns or one of its Affiliates  delivers an Offer Notice
to  Calpine  within the  Initial  Period,  but  neither  Calpine  nor any of its
Affiliates  delivers an Election Notice to Bear Stearns during the Offer Period,
Calpine or its Affiliate may, during the period beginning on the sixth (6th) day
following  the receipt of the Offer Notice by Calpine and ending on the fiftieth
(50th) day following  the receipt of the Offer Notice by Calpine,  Transfer to a
Third Party all (but not less than all) of the Equity  Securities  and/or Assets
covered by the Initial Notice, (x) for the purchase price and on the other terms


                                       19


and  conditions  contained in the Offer Notice or (y) for a purchase  price more
favorable  financially  to Calpine,  and on other terms at least as favorable to
Calpine, as those contained in the Offer Notice;  provided that if a Third Party
transferee  has accepted such offer,  Calpine shall have completed such Transfer
within an  additional  one hundred  eighty (180) days from the end of such fifty
(50) day period; and provided,  further, that, with respect to any such Transfer
that is not completed  within the time periods set forth in this Section 3.3(d),
Calpine  shall not complete  such Transfer  without  again  complying  with each
provision of this Section 3.3, as applicable.

          (e) In  addition  to  the  foregoing  restrictions,  Calpine  (or  the
applicable  Calpine  Transaction  Party or  Affiliate)  shall not  complete  any
Transfer  pursuant to Section  3.3(b) or Section  3.3(d)  without  receiving the
prior consent of Bear Stearns to the transferee of such  Transfer,  such consent
with  respect to any  proposed  Third Party  transferee  not to be  unreasonably
withheld or delayed  after  Calpine's  (or the  applicable  Calpine  Transaction
Party's or  Affiliate's)  request for such  consent  (and in no event shall such
consent take more than the longer of ten (10) Business Days following receipt of
such request by Bear Stearns or the time remaining  until the end of the Initial
Period or the Offer Period, as applicable);  provided that Bear Stearns may give
or withhold such consent in its sole and absolute discretion with respect to any
proposed Transfers to a Restricted Transferee.  Calpine may make the request for
such  consent at any time  following  delivery of an Initial  Notice,  including
contemporaneously with the applicable Initial Notice; provided that Calpine must
provide the  identity of any  proposed  Third Party  transferee  (as well as the
identity of the ultimate  operating and holding company parent,  if any, of each
proposed  Third  Party  transferee,  if the  identity of such  Person(s)  is not
readily  apparent) in each request for consent,  and otherwise  comply with this
Section 3.3.  Any consent  given to a Transfer  pursuant to this Section  3.3(e)
shall expire (i) if no proposed  Third Party  transferee  mentioned in a request
for  consent and  approved  by Bear  Stearns  has  accepted  Calpine's  offer to
Transfer the Equity  Securities  and/or Assets  covered by the Initial Notice in
accordance  with Section  3.3(b) or Section 3.3(d) by the end of the ninety (90)
day period set forth in Section 3.3(b) or the fifty (50) day period set forth in
Section 3.3(d),  respectively,  at the end of such period, or (ii) if a proposed
Third Party  transferee  approved by Bear  Stearns has accepted  such offer,  if
Calpine's  Transfer to such Third Party transferee has not been completed within
an additional  one hundred eighty (180) days from the end of the ninety (90) day
period  set forth in  Section  3.3(b) or the fifty  (50) day period set forth in
Section 3.3(d), as applicable.

          (f)  Calpine  further  agrees  that in  connection  with any  Transfer
subject to this Section 3.3  consented to by Bear  Stearns,  Calpine  shall,  if
requested  by Bear  Stearns,  deliver to Bear  Stearns  an  opinion of  external
counsel  in form and  substance  reasonably  satisfactory  to Bear  Stearns  and
counsel for Bear Stearns, to the effect that the Transfer is not in violation of
this Agreement,  and, with respect to a Transfer of any Equity Security,  is not
in violation of the  Securities  Act or the  securities  laws of any State.  Any
purported Transfer in violation of the provisions of this Section 3.3, including
any Transfer to a Third Party made without Bear Stearns' prior consent, shall be
null and void and shall have no force or effect.

          (g) Notwithstanding  anything herein to the contrary, this Section 3.3
shall not apply to (i) a Transfer to Calpine or any of its Affiliates,  provided
that if such Transfer is a Transfer of (A) Assets from CMSC, such Transfer is to


                                       20


an Affiliate of Calpine that is Bankruptcy  Remote,  or (B) Equity Securities of
CMSC, following such Transfer CMSC is Bankruptcy Remote, (ii) a Transfer to Bear
Stearns  or any of its  Affiliates,  or (iii) a  Transfer  to any Person or such
Person's  Subsidiaries if such Person or its Subsidiaries  merge with Calpine or
purchase all or substantially all of the Equity Securities or Assets of Calpine.

          (h) In  addition  to the  restrictions  set  forth  elsewhere  in this
Agreement,  in the event of a proposed  Transfer  to a Third Party by Calpine or
any of its  Affiliates  of Equity  Securities  and/or Assets of CMSC pursuant to
this Section 3.3,  Bear Stearns'  consent to such  Transfer  shall not be deemed
unreasonably  withheld  if such Third  Party  does not agree to become  bound in
writing at the  closing of such  Transfer  by the terms and  conditions  of this
Agreement and the other Transaction Documents and agree to assume the rights and
obligations of Calpine and all of the Calpine  Transaction Parties hereunder and
thereunder  pursuant  to  one  or  more  instruments  of  assumption  reasonably
satisfactory  in form and substance to Bear Stearns.  Notwithstanding  the other
provisions of this Section 3.3,  unless  expressly  waived by Bear Stearns,  any
otherwise  permitted  Transfer  shall be null and void ab initio if Bear Stearns
does not receive written  instruments  with respect to such Transfer  (including
copies of any instruments of assumption and the Third Party transferee's consent
to  be  bound  by  this  Agreement  and  the  other  Transaction  Documents,  as
applicable) that are in a form reasonably  satisfactory in form and substance to
Bear Stearns. Upon the execution of such instruments of assumption by such Third
Party,  such  Third  Party  shall  be  deemed  to be  Calpine  and  the  Calpine
Transaction Parties for all purposes of this Agreement.

   3.4    Certain Restrictions on Sales by Bear Stearns of Equity Securities and
Assets of CalBear.

          (a) Bear Stearns  hereby agrees that it shall not, and shall cause its
Affiliates not to, directly or indirectly (through the sale of Equity Securities
in an Affiliate or  otherwise),  Transfer  any Equity  Securities  of, or all or
substantially  all of the Assets of,  CalBear,  except in  compliance  with this
Section  3.4. If Bear  Stearns or any of its  Affiliates  wishes to Transfer any
such Assets or Equity Securities, Bear Stearns shall first deliver to Calpine an
Initial  Notice signed by Bear Stearns (and any such  Affiliate,  if applicable)
setting forth the Equity Securities and/or Assets proposed to be Transferred and
the material terms of the proposed Transfer other than the price.

          (b) Upon  receipt of an Initial  Notice,  Calpine  and its  Affiliates
shall have the Initial  Period to submit an Offer Notice  signed by Calpine (and
any such Affiliate,  if applicable)  setting forth (A) a proposed purchase price
with respect to the Equity  Securities  and/or Assets proposed to be Transferred
and (B) Calpine's (or such Affiliate's)  offer (irrevocable by its terms for the
Offer Period) to purchase from Bear Stearns or any of its  Affiliates the Equity
Securities  and/or  Assets  described  in the Initial  Notice,  on the terms and
conditions  described in the Initial Notice and for the purchase price set forth
in the Offer  Notice.  If an Offer Notice is  delivered  prior to the end of the
Initial  Period,  the Initial  Period  shall end on the date of delivery of such
Offer  Notice and the Offer  Period  shall  commence  on such  date.  If neither
Calpine  nor any of its  Affiliates  delivers  an Offer  Notice to Bear  Stearns
within the Initial Period,  Bear Stearns or its Affiliate may, during the period
beginning on the  forty-sixth  (46th) day  following  the receipt of the Initial
Notice by Calpine and ending on the  ninetieth  (90th) day following the receipt


                                       21


of the Initial  Notice by  Calpine,  Transfer to a Third Party all (but not less
than all) of the Equity  Securities and/or Assets covered by the Initial Notice,
for a purchase price negotiated  between Bear Stearns or such Affiliate and such
Third  Party and on other terms and  conditions  at least as  favorable  to Bear
Stearns as those contained in the Initial Notice; provided that if a Third Party
transferee  has accepted  such offer,  Bear Stearns  shall have  completed  such
Transfer within an additional one hundred eighty (180) days from the end of such
ninety (90) day period;  and provided,  further,  that, with respect to any such
Transfer that is not completed within the time periods set forth in this Section
3.4(b),  Bear  Stearns  shall  not  complete  any such  Transfer  without  again
complying with each provision of this Section 3.4, as applicable.

          (c) Upon receipt of an Offer Notice,  Bear Stearns and its  Affiliates
shall have the option to sell the Equity  Securities  and/or Assets described in
the Initial Notice to Calpine (or its Affiliate,  as applicable) at the purchase
price and upon the terms and conditions  specified in the Offer. If Bear Stearns
or any of its  Affiliates  desires  to  exercise  the  option  set  forth in the
preceding  sentence,  it shall deliver an Election Notice to Calpine at any time
during the Offer Period,  which Election  Notice shall specify that Bear Stearns
or any of its  Affiliates has elected to exercise its option to accept the Offer
and sell the Equity  Securities and/or Assets described in the Initial Notice to
Calpine (or its  Affiliate,  as applicable) on the terms set forth in the Offer.
If Bear Stearns or any of its Affiliates  delivers an Election Notice during the
Offer Period, then Calpine (or its Affiliates, as applicable) shall be obligated
to  purchase  and Bear  Stearns  (or such  Affiliate,  as  applicable)  shall be
obligated to sell, the Equity  Securities and/or Assets described in the Initial
Notice at the purchase price and on the other terms and conditions  indicated in
the Offer.  The closing of such  purchase and sale shall occur on a closing date
selected by Calpine or such Affiliate,  as applicable;  provided,  however, that
such closing date shall be not less than ten (10) days nor more than ninety (90)
days following the date of the Election Notice,  unless more time is required to
obtain any applicable regulatory or other approvals. If neither Bear Stearns nor
any of its Affiliates  delivers an Election Notice to Calpine (or its Affiliate,
as applicable) within the Offer Period, the Offer shall automatically  expire at
the end of the Offer Period and neither Calpine nor any of its Affiliates  shall
have any obligation to purchase the Equity Securities and/or Assets described in
the Initial Notice.

          (d) If Calpine or one of its  Affiliates  delivers an Offer  Notice to
Bear Stearns within the Initial Period,  but neither Bear Stearns nor any of its
delivers an Election Notice to Calpine during the Offer Period,  Bear Stearns or
its Affiliate may, during the period  beginning on the sixth (6th) day following
the  receipt of the Offer  Notice by Bear  Stearns  and  ending on the  fiftieth
(50th) day following  the receipt of the Offer Notice by Bear Stearns,  Transfer
to a Third  Party all (but not less than all) of the  Equity  Securities  and/or
Assets  covered by the Initial  Notice,  (x) for the  purchase  price and on the
other terms and  conditions  contained in the Offer Notice or (y) for a purchase
price more favorable financially to Bear Stearns, and on other terms at least as
favorable to Bear Stearns, as those contained in the Offer Notice; provided that
if a Third Party  transferee  has accepted  such offer,  Bear Stearns shall have
completed such Transfer  within an additional one hundred eighty (180) days from
the end of such fifty (50) day period; and provided, further, that, with respect
to any such Transfer that is not completed  within the time periods set forth in
this Section 3.4(d), Bear Stearns shall not complete such Transfer without again
complying with each provision of this Section 3.4, as applicable.


                                       22


          (e) In addition to the  foregoing  restrictions,  Bear Stearns (or the
applicable Affiliate) shall not complete any Transfer pursuant to Section 3.4(b)
or  Section  3.4(d)  without  receiving  the prior  consent  of  Calpine  to the
transferee  of such  Transfer,  such consent with respect to any proposed  Third
Party transferee not to be unreasonably  withheld or delayed after Bear Stearns'
(or the applicable  Affiliate's) request for such consent (and in no event shall
such  consent  take more than the  longer of ten (10)  Business  Days  following
receipt of such  request by Calpine or the time  remaining  until the end of the
Initial Period or the Offer Period,  as  applicable);  provided that Calpine may
give or withhold such consent in its sole and absolute  discretion  with respect
to any proposed Transfers to a Restricted Transferee.  Bear Stearns may make the
request for such consent at any time  following  delivery of an Initial  Notice,
including  contemporaneously  with the applicable Initial Notice;  provided that
Bear Stearns must  provide the identity of any proposed  Third Party  transferee
(as well as the identity of the ultimate  operating and holding  company parent,
if any,  of each  proposed  Third  Party  transferee,  if the  identity  of such
Person(s) is not readily  apparent) in each request for consent,  and  otherwise
comply with this Section 3.4. Any consent  given to a Transfer  pursuant to this
Section 3.4(e) shall expire (i) if no proposed Third Party transferee  mentioned
in a request for consent and  approved  by Calpine has  accepted  Bear  Stearns'
offer to Transfer the Equity  Securities  and/or  Assets  covered by the Initial
Notice in  accordance  with Section  3.4(b) or Section  3.4(d) by the end of the
ninety (90) day period set forth in Section  3.4(b) or the fifty (50) day period
set forth in Section 3.4(d), respectively, at the end of such period, or (ii) if
a proposed Third Party  transferee  approved by Calpine has accepted such offer,
if Bear Stearns'  Transfer to such Third Party transferee has not been completed
within an  additional  one hundred  eighty (180) days from the end of the ninety
(90) day  period  set forth in  Section  3.4(b) or the fifty (50) day period set
forth in Section 3.4(d), as applicable.

          (f) Bear Stearns  further agrees that in connection  with any Transfer
subject to this Section 3.4  consented to by Calpine,  Bear  Stearns  shall,  if
requested by Calpine,  deliver to Calpine an opinion of external counsel in form
and substance reasonably satisfactory to Calpine and counsel for Calpine, to the
effect that the Transfer is not in violation  of this  Agreement,  and is not in
violation  of the  Securities  Act or the  securities  laws  of any  State.  Any
purported Transfer in violation of the provisions of this Section 3.4, including
any Transfer to a Third Party made without  Calpine's  prior  consent,  shall be
null and void and shall have no force or effect.

          (g) Notwithstanding  anything herein to the contrary, this Section 3.4
shall not apply to (i) a Transfer to Bear Stearns or any of its Affiliates, (ii)
a Transfer  to Calpine or any of its  Affiliates,  including  any such  Transfer
pursuant to Section 16.6(d),  or (iii) a Transfer to any Person or such Person's
Subsidiaries  if such  Person or its  Subsidiaries  merge  with Bear  Stearns or
purchase all or  substantially  all of the Equity  Securities  or Assets of Bear
Stearns.

          (h) In  addition  to the  restrictions  set  forth  elsewhere  in this
Agreement,  in the event of a proposed Transfer to a Third Party by Bear Stearns
or any of its Affiliates of Equity  Securities and/or Assets of CalBear pursuant
to this  Section 3.4,  Calpine's  consent to such  Transfer  shall not be deemed
unreasonably  withheld  if such Third  Party  does not agree to become  bound in
writing at the  closing of such  Transfer  by the terms and  conditions  of this
Agreement and the other Transaction Documents and agree to assume the rights and
obligations of Bear Stearns and CalBear hereunder and thereunder pursuant to one


                                       23


or more instruments of assumption reasonably  satisfactory in form and substance
to Calpine.  Notwithstanding  the other  provisions of this Section 3.4,  unless
expressly waived by Calpine,  any otherwise permitted Transfer shall be null and
void ab initio if Calpine does not receive written  instruments  with respect to
such Transfer  (including  copies of any instruments of assumption and the Third
Party  transferee's  consent  to be  bound  by  this  Agreement  and  the  other
Transaction Documents, as applicable) that are in a form reasonably satisfactory
in form and  substance to Calpine.  Upon the  execution of such  instruments  of
assumption  by such Third  Party,  such Third  Party  shall be deemed to be Bear
Stearns and CalBear for all purposes of this Agreement.

          (i) In  addition  to the  restrictions  set  forth  elsewhere  in this
Agreement,  in the event of a proposed Transfer to a Third Party by Bear Stearns
or any of its Affiliates of Equity  Securities and/or Assets of CalBear pursuant
to this  Section 3.4,  Calpine's  consent to such  Transfer  shall not be deemed
unreasonably  withheld  if such Third  Party  does not have,  at the time of the
transfer, a credit rating by (i) Standard & Poors Ratings Group of at least BBB+
and (ii) Moody's Investor Services of at least Baa1.

   3.5    No Joint Venture or Partnership Created.

          (a) Calpine and the Calpine Transaction  Parties, on the one hand, and
Bear  Stearns and  CalBear,  on the other  hand,  are  independent  contractors.
Neither  Calpine or any Calpine  Transaction  Party,  on the one hand,  nor Bear
Stearns or  CalBear,  on the other  hand,  is an agent  (except as  specifically
provided in the Agency and  Services  Agreement),  representative  or partner of
Bear  Stearns  or  CalBear,   or  Calpine  or  any  Calpine  Transaction  Party,
respectively,  and each of Calpine and the Calpine  Transaction Parties and Bear
Stearns  and CalBear  agrees that the  Transaction,  this  Agreement,  the other
Transaction  Documents and the transactions  contemplated hereby and thereby are
not  intended to create,  and shall not be  interpreted,  construed or deemed to
create  in  any   respect   an   association,   joint   venture,   co-ownership,
co-authorship,  or partnership,  whether general, limited or otherwise,  between
Calpine or any Calpine  Transaction  Party, on the one hand, and Bear Stearns or
CalBear,  on  the  other  hand,  or to  impose  any  partnership  obligation  or
partnership  liability between Calpine or any Calpine  Transaction Party, on the
one hand, and Bear Stearns or CalBear, on the other hand. None of Calpine or any
Calpine  Transaction Party, on the one hand, nor Bear Stearns or CalBear, on the
other hand,  shall have any right,  power or  authority to  negotiate,  execute,
authenticate  or deliver any  Contract for or on behalf of or in the name of, or
to incur any  Liability  for, or to  otherwise  bind,  Bear  Stearns or Calpine,
respectively,  or  bind  CalBear  or  any of the  Calpine  Transaction  Parties,
respectively,  except as  specifically  set  forth in the  Agency  and  Services
Agreement or the Trading Master Agreement,  in each case with respect to CalBear
and CMSC. Calpine and the Calpine Transaction Parties, on the one hand, and Bear
Stearns and CalBear,  on the other hand,  agree that they are not, and shall not
be, and shall not hold Bear  Stearns  or  CalBear,  or  Calpine  or the  Calpine
Transaction Parties, respectively, out to be, co-employers.

          (b) The Parties will determine a public description of the Transaction
mutually  satisfactory  to Calpine and Bear  Stearns.  Calpine and Bear  Stearns
shall not, and shall cause their  Affiliates not to, make any press release that
is materially  inconsistent with such public  description.  Reference is made to
Section 18.13 for other agreements with respect to press releases.


                                       24


   3.6    Conflicts of Interest; Non-Discrimination.

          (a)  Conflicts of Interest.  Calpine,  CMSC,  Bear Stearns and CalBear
acknowledge  that CMSC is providing the Services to CalBear and that Calpine (a)
indirectly  owns a one hundred  percent  (100%) equity  interest in CMSC and (b)
either  directly  or  indirectly   through  one  or  more  of  its  wholly-owned
Subsidiaries,  including  CES or  CMSC,  is  conducting  for its own  account  a
business similar to the CalBear Referral Business.  Accordingly,  Calpine, CMSC,
Bear Stearns and CalBear  acknowledge  and agree that  conflicts  may arise from
time to time between the interests of CalBear,  on the one hand,  and CMSC,  CES
and Calpine's other Affiliates,  on the other hand. In addition,  Calpine, CMSC,
Bear Stearns and CalBear  acknowledge  and agree that CMSC may provide  services
similar to the  Services  with  respect to  transactions  entered  into by Third
Parties or for or on behalf of Third  Parties by CMSC.  The Parties  acknowledge
that Section 4.2 of the Agency and Services Agreement contains certain covenants
of CMSC  representing  the sole and  exclusive  agreement  of the  Parties  with
respect to such conflicts of interest.

          (b) Non-Discrimination.  Calpine agrees that it shall, and shall cause
its Affiliates to, cause CMSC to comply with its obligations pursuant to Section
4.2 of the Agency and Services Agreement.  Calpine agrees that it shall not, and
shall cause its  Affiliates not to, take any action or enter into any agreement,
transaction or arrangement with the purpose of avoiding CMSC's obligations under
Section  4.2 of the  Agency  and  Services  Agreement,  including  by  providing
services  substantially  similar to the Services  through  Calpine or any of its
Affiliates  other  than  CES  or  CMSC  with  the  purpose  of  avoiding  CMSC's
obligations under Section 4.2 of the Agency and Services Agreement.

   3.7    Non-Solicitation of Bear Stearns Employees.

          (a) Prior to the termination of this Agreement and for a period of one
(1) year following the date of termination  of this  Agreement,  each of Calpine
and the Calpine  Transaction Parties shall not, and shall cause their Affiliates
not to, directly or indirectly, for itself or on behalf of any other Person, (i)
hire any employee of Bear Stearns or CalBear who is involved in the transactions
contemplated hereby or by the other Transaction  Documents or the CalBear Trades
and who is listed on Schedule  3.7(a)  (provided that Schedule  3.7(a) shall not
initially  include more than [*]  employees) (A) while such employee is employed
by Bear Stearns or CalBear, or (B) in the event of a voluntary  resignation from
Bear Stearns or CalBear of an employee  listed on Schedule 3.7(a) at the time of
such resignation,  for a period of (60) days following such resignation, or (ii)
solicit,  induce or attempt to solicit or induce any employee of Bear Stearns or
CalBear  listed on  Schedule  3.7(a) to leave  his or her  employment  with Bear
Stearns or CalBear,  as applicable;  provided that a general  solicitation or an
employment agency  solicitation that is not directed to specifically  target any
such employee shall not be deemed to violate this Section  3.7(a)(ii) so long as
Calpine,  the Calpine  Transaction  Parties and their Affiliates do not hire any
such employee as a result of such solicitation or inducement.

          (b) Once each calendar year,  commencing with calendar year 2006, Bear
Stearns  may modify  Schedule  3.7(a) to (i)  increase  the number of  employees
listed on Schedule 3.7(a) up to the number of employees that Calpine includes on
Schedule 3.8(a),  and/or (ii) remove  employees from Schedule  3.7(a);  provided


                                       25


that if Bear Stearns modifies Schedule 3.7(a) to remove any employee  therefrom,
Section  3.7(a)  shall no  longer  apply  with  respect  to such  employee;  and
provided,  further,  that such  modifications  to Schedule  3.7(a)  shall not be
effective  until Bear Stearns  provides a copy of such modified  Schedule 3.7(a)
(highlighting any  modifications  thereto) to Calpine in accordance with Section
18.2. In addition, after (i) the dismissal or termination of any employee listed
on Schedule  3.7(a) or (ii) sixty (60) days have  elapsed  following a voluntary
resignation  of an employee  listed on Schedule  3.7(a),  Schedule  3.7(a) shall
automatically be modified to remove the name of such employee,  and Bear Stearns
shall  promptly  provide a copy of such modified  Schedule  3.7(a) to Calpine in

the  Calpine  Transaction  Parties or their  Affiliates  shall be deemed to have
violated  Section  3.7(a) until Bear Stearns  provides  notice to Calpine of the
hiring  and/or  solicitation  of any  employee  of Bear  Stearns  or  CalBear in
violation of Section 3.7(a) (which notice contains the name,  title and position
of the employee hired in violation of Section  3.7(a) or details  concerning the
solicitation violating Section 3.7(a)) and Bear Stearns has provided Calpine the
opportunity  to cure such  violation in  accordance  with this  Section  3.7(c).
During the  period  commencing  on the date of  receipt  of any such  notice and
ending on the thirtieth  (30th) day thereafter  (subject to an extension for any
retention period or other period required by Applicable  Law),  Calpine shall be
entitled to cure any  violation  of Section  3.7(a) by  dismissing  the employee
named in the notice (on terms  determined  by  Calpine  in its  discretion,  but
subject  to the  length  of the cure  period  described  above) or  ceasing  the
activity causing the solicitation described in the notice, as applicable.

or  indirectly,  for  itself  or on behalf  of any  other  Person,  (i) hire any
employee  of Calpine or any  Calpine  Transaction  Party who is  involved in the
transactions  contemplated  hereby or by the other Transaction  Documents or the

(B)  in the  event  of a  voluntary  resignation  from  Calpine  or any  Calpine
Transaction  Party of an employee  listed on Schedule 3.8(a) at the time of such
resignation,  for a period  of (60) days  following  such  resignation,  or (ii)
solicit,  induce or attempt to solicit or induce any  employee of Calpine or any
Calpine  Transaction  Party  listed  on  Schedule  3.8(a)  to  leave  his or her
employment  with  Calpine  or any  Calpine  Transaction  Party,  as  applicable;
provided that a general  solicitation or an employment agency  solicitation that
is not directed to specifically  target any such employee shall not be deemed to
violate  this Section  3.8(a)(ii)  so long as Bear Stearns and CalBear and their
Affiliates  do not hire any such  employee as a result of such  solicitation  or
inducement.

          (b) Once each  calendar  year,  commencing  with  calendar  year 2006,
Calpine may modify Schedule 3.8(a) to (i) proportionally  increase the number of
employees  listed on  Schedule  3.8(a) to  reflect  increases  in the  number of


                                       26


employees of CMSC,  and/or (ii) remove employees from Schedule 3.8(a);  provided
that if  Calpine  modifies  Schedule  3.8(a) to remove any  employee  therefrom,
Section  3.8(a)  shall no  longer  apply  with  respect  to such  employee;  and
provided,  further,  that such  modifications  to Schedule  3.8(a)  shall not be
effective  until  Calpine  provides  a copy of  such  modified  Schedule  3.8(a)
(highlighting  any  modifications  thereto) to Bear Stearns in  accordance  with

employee  listed on  Schedule  3.8(a)  or (ii)  sixty  (60)  days  have  elapsed
following a voluntary  resignation  of an  employee  listed on Schedule  3.8(a),
Schedule  3.8(a)  shall  automatically  be  modified  to remove the name of such
employee,  and Calpine shall promptly  provide a copy of such modified  Schedule
3.8(a) to Bear Stearns in accordance with Section 18.2.

          (c)  Notwithstanding  the provisions of Section  3.8(a),  none of Bear
Stearns,  CalBear or their  Affiliates  shall be deemed to have violated Section
3.8(a)  until  Calpine  provides  notice to Bear  Stearns of the  hiring  and/or
solicitation  of any  employee  of Calpine or any Calpine  Transaction  Party in
violation of Section 3.8(a) (which notice contains the name,  title and position
of the employee hired in violation of Section  3.8(a) or details  concerning the
solicitation violating Section 3.8(a)) and Calpine has provided Bear Stearns the
opportunity  to cure such  violation in  accordance  with this  Section  3.8(c).
During the  period  commencing  on the date of  receipt  of any such  notice and
ending on the thirtieth  (30th) day thereafter  (subject to an extension for any
retention period or other period required by Applicable Law), Bear Stearns shall
be entitled to cure any violation of Section  3.8(a) by dismissing  the employee

   3.9    Confidential Information.

          (a) Prior to the termination of this Agreement and for a period of one
(1) year following the  termination of this  Agreement,  the Parties shall,  and
shall cause their respective  Affiliates and Representatives to, (i) maintain in
strict  confidence any and all Confidential  Information  concerning the Parties
and the CalBear Business (including the CalBear Information) and not disclose to
any Third Party any such  Confidential  Information and (ii) restrict the use of
Confidential  Information to prevent  anticompetitive use of such information in
violation of antitrust laws, including with respect to Confidential  Information
regarding  trading  positions,   pricing  models,  projected  trades  and  other
commercial information related to the Power and Gas trading markets developed by
CMSC, with respect to compliance by Bear Stearns and CalBear,  or CalBear,  with
respect to compliance by Calpine and the Calpine Transaction  Parties;  provided
that the  foregoing  obligations  shall  not  apply to  Calpine  or the  Calpine
Transaction  Parties in  connection  with a disclosure by Calpine or the Calpine
Transaction  Parties of the aggregate  net portfolio  positions of CES, but, for
the  avoidance  of doubt,  shall  apply with  respect to any  individual  Credit
Enhancement Trade or any disclosure that, directly or indirectly,  would allow a
Third Party to identify or otherwise  directly determine the terms of any Credit
Enhancement  Trade.  It is  understood  that  the  Parties  shall  not  have any
liability hereunder with respect to information that (i) is, or through no fault
of the Parties or any of their respective Affiliates or Representatives becomes,
generally  available to the public,  (ii) is received  from a Third Party and is


                                       27


not subject to any  confidentiality  obligation  between the receiving  Party or
Parties  and such  Third  Party,  (iii) is  independently  developed  by a Party
without  the use of the  Confidential  Information,  (iv) the  Parties  or their
respective  Affiliates or Representatives  are legally required to disclose,  or
that is the subject of any disclosure request made by any Governmental Authority
or by any Third  Party  pursuant  to  Applicable  Law,  or (v) is  necessary  in
connection with the defense or prosecution of any Action.

          (b)  In  the  event  that  a  Party  or  any  of  its   Affiliates  or
Representatives   is  required  or  requested   to  disclose  any   Confidential
Information  pursuant to Section  3.9(a)(iv)  or (v),  such Party shall,  unless
prohibited or otherwise  required by Applicable Law, if an Affiliate of Calpine,
promptly  notify Bear  Stearns,  or if an  Affiliate of Bear  Stearns,  promptly
notify Calpine,  so that the Parties may cooperate in seeking a protective order
and/or other motion,  at the expense of the Party seeking such protective  order
and/or other  motion,  to prevent or limit the  production or disclosure of such
Confidential  Information.  If such  protective  order is not  obtained  or such
motion has been denied,  then the Person  required or requested to disclose such
Confidential  Information  may disclose  only that portion of such  Confidential
Information  which,  based on the advice of such Person's outside legal counsel,
is required by  Applicable  Law or requested by a  Governmental  Authority to be
disclosed  (provided  that the Person  required or  requested  to disclose  such
information shall use all reasonable efforts to preserve the  confidentiality of
the remainder of such Confidential  Information).  Such Person shall continue to
be bound by its  obligations  pursuant to this Section 3.9 for any  Confidential
Information that is not required or requested to be disclosed,  or that has been
afforded protective treatment, pursuant to such order or motion.

          (c)   Notwithstanding   the   provisions  of  Section   3.9(a)  above,
disclosures of  Confidential  Information may be made (i) in the ordinary course
of CalBear's  business,  but only to the extent reasonably  necessary to conduct
such  business,  (ii) to each  Party's  advisors,  auditors,  legal  counsel and
insurers  and lenders who  reasonably  need to have access to such  Confidential
Information  in  connection  with  the  performance  of  their  work,  (iii)  to
Representatives of Calpine and its Affiliates who reasonably need to have access
to such  Confidential  Information in connection  with the  performance of their
work, (iv) to  Representatives of Bear Stearns and its Affiliates who reasonably
need to have access to such  Confidential  Information  in  connection  with the
performance of their work, (v) to bona fide potential Third Party  purchasers of
an  interest  in any  Party or its  Subsidiaries,  but in each  case only to the
extent  required in  connection  with such  transaction;  provided that any such
Third Party  receiving  any  Confidential  Information  agrees to  maintain  the
confidentiality  of such  Confidential  Information in accordance with the terms
hereof, and (vi) by any Party or any of their respective  Affiliates at any time
in  connection  with  any  reporting  requirements  of  such  Person  under  any
Applicable Law, any bona fide debt or equity financing of such Person,  any bona
fide  merger  or  sale  of  such  Person,  or  any  bona  fide  sale  of  all or
substantially  all of such Person's Assets,  but in each case only to the extent
reasonably necessary in connection with such transaction,  and such Confidential
Information  may  be  included  in  any  financial   statements,   schedules  or
information,  any diligence  materials or any prospectus,  offering  memorandum,
information  statement or proxy  statement  provided to any Person in connection
therewith  (provided that any such disclosure pursuant to this clause (vi) shall
not include the terms of any individual  CalBear Trade or any  disclosure  that,


                                       28


directly or  indirectly,  would  allow a Third  Party to  identify or  otherwise
directly  determine the terms of any  individual  CalBear  Trade,  without prior
notice to each Party that is not an  Affiliate  of the  disclosing  Party unless
prohibited by Applicable Law).

    3.10  Netting. Except as expressly set forth in Section 4.4(e) of the Agency
and Services  Agreement,  in the event that, at any time, Calpine or any Calpine
Transaction  Party,  on the one hand,  or Bear Stearns or CalBear,  on the other
hand, is required,  pursuant to this Agreement, the other Transaction Documents,
the  transactions  contemplated  hereby or thereby,  the Services or the CalBear
Trades,  to make any  Payment to Bear  Stearns or CalBear,  on the one hand,  or
Calpine or any Calpine Transaction Party, on the other hand, respectively,  then
in each case the amounts of such Payments between or among Calpine,  the Calpine
Transaction Parties, Bear Stearns and CalBear, as applicable,  may be aggregated
and  Calpine  and the  Calpine  Transaction  Parties,  on the one hand,  or Bear
Stearns and CalBear,  on the other hand,  as  applicable,  may  discharge  their
obligations to make such Payments through  netting,  in which case the Party (or
Calpine and the Calpine Transaction Parties or Bear Stearns and CalBear, in each
case as a group),  if any, owing the greater aggregate amount to any other Party
(or Calpine and the Calpine  Transaction Parties or Bear Stearns and CalBear, in
each case as a group),  may pay to the Party (or such group of Parties) to which
the applicable  Payment or Payments are owed the difference  between the amounts
owed.  For the  avoidance  of doubt,  this  Section  3.10 is  intended to permit
netting of all amounts due among the Parties  hereto or the parties to any other
Transaction  Documents to the fullest  extent  possible.  Each Party reserves to
itself all  rights,  setoffs,  counterclaims  and other  remedies  and  defenses
consistent  with  Article  XVII (to the extent not  expressly  herein  waived or
denied)  which each such Party is or may be entitled  to arising  from or out of
this Agreement and the other  Transaction  Documents.  All  outstanding  CalBear
Trades,  Services and obligations to make Payment in connection  therewith under
this  Agreement and the other  Transaction  Documents may be offset against each
other,  set off or recouped  therefrom.  Except as provided in this Agreement or
the other Transaction  Documents,  upon the termination of this Agreement or any
other  Transaction  Document,  the Parties shall continue to net all amounts due
among them arising under this Agreement or the other Transaction Documents.

    3.11  Acknowledgements.  Each Party acknowledges that, in view of the nature
of the Transaction and the CalBear Business,  and the consideration given by the
Parties  therefore,  the restrictions  contained in Sections 3.2, 3.3, 3.4, 3.5,
3.6, 3.7,  3.8,  3.9,  3.12,  and 3.15 are  reasonably  necessary to protect the
legitimate  business  interests  of the Parties and that any  violation  of such
restrictions will result in irreparable  injury to the Parties,  the Transaction
and the CalBear Business for which damages will not be an adequate remedy.  Each
Party therefore  acknowledges that, if any such restrictions are violated by it,
each other  Party that is not an  Affiliate  of such Party  shall be entitled to
preliminary and injunctive  relief or other equitable  remedies.  Each Party has
independently consulted with its counsel and after such consultation agrees that
the  covenants  set forth in Sections  3.2,  3.3,  3.4, 3.5, 3.6, 3.7, 3.8, 3.9,
3.12, and 3.15 are reasonable and appropriate.  If the final judgment of a court
or  arbitration  body  of  competent  jurisdiction  declares  that  any  term or
provision of Sections 3.2, 3.3, 3.4, 3.5, 3.6, 3.7, 3.8, 3.9,  3.12, and 3.15 is
invalid or  unenforceable,  the Parties agree that the court or arbitration body
making the determination of invalidity or unenforceability  shall have the power
to reduce  the  scope,  duration,  or area of the term or  provision,  to delete
specific words or phrases,  or to replace any invalid or  unenforceable  term or


                                       29


provision with a term or provision that is valid and  enforceable and that comes
closest to  expressing  the  intention of the invalid or  unenforceable  term or
provision,  and this  Agreement  shall be  enforceable  as so modified after the
expiration  of the time  within  which  the  judgment  or  determination  may be
appealed.

    3.12  CMSC Board  Representation.  CalBear shall be entitled to designate up
to two (2) members of the board of directors of CMSC (each,  a "Designated  CMSC
Board  Member");  provided that each such  Designated CMSC Board Member shall be
either (a) a professional  independent  director  compensated by Bear Stearns or
its Affiliates (other than CalBear) and reasonably acceptable to Calpine, or (b)
an employee of Bear Stearns or its Affiliates with a title of Managing  Director
or equivalent  or a more senior title.  CalBear shall be entitled to designate a
replacement for any Designated  CMSC Board Member at any time,  whether upon the
death, removal or resignation of such Designated CMSC Board Member or otherwise.
If CalBear  designates any Designated CMSC Board Member at any time, Calpine and
each of the  Calpine  Transaction  Parties  agrees,  and  agrees  to  cause  its
Affiliates  to (a) vote for,  elect or appoint each such  Designated  CMSC Board
Member  designated  by  CalBear  to the  board  of  directors  of CMSC  promptly
following  such  designation,  (b) vote for,  elect or appoint  any  replacement
Designated CMSC Board Member  designated by CalBear to the board of directors of
CMSC promptly following such designation,  and (c) unless otherwise requested by
Bear Stearns, maintain the Designated CMSC Board Members (as replaced by CalBear
from time to time) as directors of CMSC at all times prior to the termination of
this Agreement.  CMSC's Organizational Documents shall provide that any decision
of the board of  directors of CMSC shall  require the consent of the  Designated
CMSC Board Members,  if any, to (i) initiate a voluntary  Bankruptcy Event, (ii)
consent to an involuntary  Bankruptcy Event, or (iii) modify the  Organizational
Documents  of CMSC to  eliminate  or  otherwise  alter the voting  rights of the
Designated  CMSC Board Members or CalBear's  right to designate,  or Calpine and
its Affiliates  duty to appoint,  such  Designated  CMSC Board  Members.  CMSC's
Organizational  Documents  shall also  provide  that the  Designated  CMSC Board
Members  shall not be entitled to vote with  respect to any matter  presented to
the board of  directors of CMSC other than the matters  listed in the  preceding
sentence.

   3.13   Performance of Financial Obligations of CalBear.

          Bear  Stearns  shall  provide  to  CalBear  all funds  and  collateral
necessary  for CalBear to perform its  obligations  under the Third Party Master
Agreements,  and the CalBear Trades,  and to pay the amounts required to be paid
by CalBear  pursuant to Section 4.17 of the Agency and Services  Agreement,  and
shall itself or shall cause  CalBear to perform  CalBear's  Payment  obligations
under the Third Party Master  Agreements and the CalBear Trades,  and to pay the
amounts  required to be paid by CalBear  pursuant to Section  4.17 of the Agency
and Services Agreement, in each case in accordance with such Section.

    3.14  [*]3.15  Fiscal Year of CalBear.  CalBear  shall not change its Fiscal
Year without the prior consent of Calpine,  such consent not to be  unreasonably
withheld;  provided  that  Calpine's  consent shall not be required in the event
that such  change is made to  conform  CalBear's  fiscal  year to Bear  Stearns'
fiscal  year in  connection  with a change of Bear  Stearns'  fiscal  year;  and
provided,  further,  that in  connection  with any change in the Fiscal  Year of


                                       30


CalBear,  the  provisions  of the  Transaction  Documents  shall be  adjusted as
applicable to conform to such adjusted fiscal year and shall also be adjusted to
the extent  necessary to give effect to the original intent of the provisions of
the Transaction  Documents,  as if such change in the Fiscal Year of CalBear had
not  occurred,  including  appropriate  proration  or  other  adjustment  of any
Payments paid pursuant to the Transaction Documents.

    3.16  Interest on Overdue Amounts.  In the event that, at any time,  Calpine
or any Calpine  Transaction  Party, on the one hand, or Bear Stearns or CalBear,
on the  other  hand,  fails to make any  Payment  when  due to Bear  Stearns  or
CalBear,  on the one hand, or Calpine or any Calpine  Transaction  Party, on the
other hand, then the outstanding  principal amount of such overdue Payment shall
bear  interest  at the  lesser of (a) a rate  equal to LIBOR  [*](or  shall bear
additional  interest  at a rate  equal  to the  existing  interest  rate on such
overdue Payment [*], if such overdue  Payment  already bears interest;  provided
that any overdue Payment  already  bearing default or additional  interest shall
not bear further interest pursuant to this Section 3.16) or (b) the highest rate
permitted by law,  until such overdue  Payment plus all  accumulated  but unpaid
interest (and additional  interest,  if applicable) thereon is paid in full, and
the Party  making such  overdue  Payment  shall pay all  accumulated  but unpaid
interest (and additional interest,  if applicable) on the amount of such overdue
Payment at the time the principal of such overdue Payment is paid.

                                  ARTICLE IV.
                               CALPINE GUARANTEE

          Calpine  covenants  and agrees with Bear Stearns and CalBear that from
and after the Effective Date:

   4.1    Calpine Guarantee.

          (a) Subject to the terms of this Article IV, in  consideration of each
of Bear Stearns and CalBear  entering into the  Transaction  Documents,  Calpine
hereby unconditionally and irrevocably guarantees, as primary obligor and not as
surety (the "Calpine Guarantee"), to each of Bear Stearns and CalBear, and their
respective successors and assigns:

               (i) the prompt  payment in full when due of all  amounts  owed by
and due from any Calpine  Transaction  Party to Bear Stearns or CalBear pursuant
to the terms of the Transaction Documents, including all amounts owed by and due
from any  Calpine  Transaction  Party to Bear  Stearns  or CalBear  pursuant  to
Section 15.1(a) and pursuant to Section 6.3 of the Trading Master Agreement; and

               (ii) that in case of any  extension  of time of payment of any of
such  obligations,  such  obligations  will be promptly paid in full when due in
accordance with the terms of the extension.

Failing payment when due of any amount so guaranteed for any reason  whatsoever,
Calpine will  promptly pay the same on the date such payment is due. The Parties
agree that this is a guarantee of payment and not a guarantee of  collection  or
performance.


                                       31


          (b) Calpine  hereby  agrees that its  obligations  under this  Calpine
Guarantee are  absolute,  irrevocable  and  unconditional,  irrespective  of the
validity,   regularity  or   enforceability  of  this  Agreement  or  the  other
Transaction Documents, the absence of any Action to enforce the same, any waiver
or consent by Bear Stearns or CalBear,  any course of dealings among the Parties
with respect to any provisions  hereof or thereof,  the recovery of any judgment
against any  Calpine  Transaction  Party,  any Action to enforce the same or any
other  circumstance  which  might  otherwise  constitute  a legal  or  equitable
discharge of defense of Calpine.  Calpine hereby waives diligence,  presentment,
demand of payment,  filing of claims with a court in the event of any Bankruptcy
of Calpine or any Calpine  Transaction  Party, any right to require a proceeding
first against any Calpine  Transaction  Party,  protest,  notice and all demands
whatsoever  and  covenants  that this Calpine  Guarantee  will not be discharged
except by complete performance and payment of the obligations  contained in this
Agreement and the other Transaction Documents.

          (c) If  Bear  Stearns  or  CalBear  is  required  by any  Governmental
Authority or otherwise to return to Calpine or any Calpine  Transaction Party or
any custodian,  trustee, liquidator or other similar official acting in relation
to Calpine or any  Calpine  Transaction  Party,  any amount paid by them to Bear
Stearns  or  CalBear,   this  Calpine  Guarantee,   to  the  extent  theretofore
discharged,  will be  reinstated  in full force and effect with  respect to such
amount.

          (d)  Calpine  agrees  that it will  not be  entitled  to any  right of
subrogation in relation to Bear Stearns or CalBear in respect of any obligations
guaranteed  hereby until payment in full of all obligations  guaranteed  hereby.
Calpine  further  agrees that,  as between  Calpine,  on the one hand,  and Bear
Stearns or CalBear,  on the other  hand,  (i) the  maturity  of any  obligations
guaranteed  hereby  that  may  be  accelerated  pursuant  to  the  terms  of the
Transaction  Documents,  may be so accelerated  for the purposes of this Calpine
Guarantee,  notwithstanding any stay, injunction or other prohibition preventing
such  acceleration in respect of the obligations  guaranteed  hereby and (ii) in
the event of any declaration of acceleration of such  obligations as provided in
the Transaction  Documents,  such  obligations  (whether or not due and payable)
will forthwith become due and payable by Calpine for the purpose of this Calpine
Guarantee.  Calpine will have the right to seek contribution from any non-paying
Calpine  Transaction Party so long as the exercise of such right does not impair
the rights of Bear Stearns or CalBear under this Calpine Guarantee.

    4.2   Calpine May Consolidate, etc., on Certain Terms.  Calpine may not sell
or  otherwise  dispose  of  all  or  substantially  all of  its  Assets  to,  or
consolidate  with or merge with or into (whether or not Calpine is the surviving
Person) another Person unless the Person acquiring the property in any such sale
or  disposition or the Person formed by or surviving any such  consolidation  or
merger  unconditionally  assumes  all the  obligations  of  Calpine  under  this
Agreement, the Calpine Guarantee and the other Transaction Documents.  Except as
set forth in this Section 4.2, nothing  contained in this Agreement will prevent
any  consolidation  or merger of  Calpine  or any sale or  conveyance  of all or
substantially all of the property of Calpine.

   4.3    Release.

full  and  final  discharge  of all  obligations  of  Calpine  and  the  Calpine
Transaction Parties under the Transaction Documents,  Calpine shall be fully and
unconditionally  released and  relieved  from any  obligation  under the Calpine
Guarantee;  provided that if, following such discharge,  Bear Stearns or CalBear
is required by any  Governmental  Authority or otherwise to return to Calpine or
any Calpine  Transaction  Party or any custodian,  trustee,  liquidator or other
similar official acting in relation to Calpine or any Calpine Transaction Party,

Parties  agree  that this is a  guarantee  of  payment  and not a  guarantee  of
collection or performance.

Calpine Transaction Parties is in compliance  with all Applicable  Laws,  except

Transaction  Party.  None of  Calpine or the  Calpine  Transaction  Parties  has
received  any written  notice to the effect  that,  and the Calpine  Transaction

                                       42


Calpine  Transaction  Party is or has been a party,  except,  in either case, as

conveyance or transfer laws.

    9.9   SEC Filings; Financial Statements.

          (a) Calpine has filed all registration statements, prospectuses, forms
and reports  required to be filed by it under the Securities Act or the Exchange
Act, as the case may be, since January 1, 2003  (collectively,  the "Calpine SEC
Filings"). Each Calpine SEC Filing, as amended or supplemented,  complied in all
material  respects with the  requirements  of the Securities Act or the Exchange
Act, as the case may be, with respect to such  Calpine SEC Filing.  Each Calpine
SEC Filing, as amended or supplemented, if applicable, did not (as so amended or
supplemented) contain any untrue statement of a material fact or omit to state a
material  fact  required to be stated  therein or necessary in order to make the
statements made therein, in the light of the circumstances under which they were
made, not misleading.

          (b) Except as may be indicated  in the notes  thereto and, in the case
of unaudited  quarterly financial  statements,  except as permitted by Form 10-Q
under  the  Exchange  Act,  each  of  the  consolidated   financial   statements
(including,  in each case,  any notes  thereto)  contained  in the  Calpine  SEC
Filings was  prepared in  accordance  with GAAP  applied on a  consistent  basis
throughout the periods indicated,  and, at the time such consolidated  financial
statements  were  filed and at the time they were  amended or  supplemented,  if
applicable,  each fairly  presented  in all material  respects the  consolidated
financial  position of Calpine and its  subsidiaries as of the respective  dates
thereof and for the respective  periods indicated therein (subject,  in the case
of unaudited statements, to normal, recurring year-end adjustments which did not
have a Material Adverse Effect on Calpine).

   9.10   Regulation.

          (a)  Neither  Calpine nor any of the  Calpine  Transaction  Parties is
subject to regulation as an "electric  utility company," a "gas utility company"
a  "public-utility  company,"  or  a  "holding  company,"  under  PUHCA  or  any
regulation  promulgated  thereunder.  Neither  Calpine  nor  any of the  Calpine
Transaction Parties is subject to material  regulatory  restrictions under PUHCA
(other than Section 9(a)(2) of PUHCA).

          (b) CES and CMSC each have validly issued final orders authorizing CES
and CMSC,  respectively,  to engage in Power sales at wholesale at  market-based
rates.  CES and  CMSC  are in  compliance  with all  FERC  reporting  and  other
requirements  generally  imposed on entities  authorized  to engage in wholesale
sales of Power at market-based rates,  including requirements to file electronic
quarterly  transaction  reports,  triennial  market-power updates and changes in
status,  except  to the  extent  that  non-compliance  could not  reasonably  be
expected to cause a Material Adverse Effect with respect to CES or CMSC.


                                       43


    9.11  Due  Consideration.   Calpine  and  the  Calpine  Transaction  Parties
acknowledge  that they will  generally  obtain more  favorable  terms for Trades
through the Transaction than the terms that are currently  available to them for
similar  transactions with Third Parties and Calpine and the Calpine Transaction
Parties  desire  Bear  Stearns  to  provide  financial  support  as  part of the
Transaction  in order to enhance the credit of certain Gas and Power trades made
by  CalBear  and CES and in order to  otherwise  support  certain  Gas and Power
trading activities of the Calpine Transaction  Parties.  Calpine and the Calpine
Transaction  Parties have received due and adequate  consideration  and fair and
equivalent value for their  agreements and obligations  under this Agreement and
the other Transaction Documents as determined in good faith, in each case within
the meaning of applicable state and federal fraudulent conveyance laws.

    9.12  Operations  of CMSC.  CMSC  has not taken any  action  that would have
violated Section 4.1(m) of the Agency and Services Agreement had it been subject
to such Section  4.1(m) on the Effective  Date.  Except in  connection  with the
transactions  contemplated  by the  Transaction  Documents  or the  provision of
energy  related  services  to CES,  CMSC does not have any  Contracts  with,  or
Liabilities to, Third Parties or its Affiliates.

    9.13  Material  Contracts  of CMSC.  At least  ten (10)  days  prior to the
Effective  Date,  CMSC has  provided to Bear  Stearns and CalBear  copies of all
material  Contracts to which CMSC is a party and copies of all Contracts  listed
on Schedules 4.1(m) to the Agency and Services Agreement.

          Calpine  Transaction  Parties  or any of  their  Affiliates  or  their
          respective  Representatives,  in each  case  to the  extent  that  the
          Damages to a Bear  Stearns  Party  arose out of or  resulted  from the

          that Bear Stearns or CalBear are parties to the Transaction Documents;

               (ii) The  indemnity  provided for in this Section  15.1(a) is not

          (III)  incurred in the same Fiscal Year in the  aggregate  exceed $[*]
          million  (provided  that the  occurrence of losses or gains on CalBear

          respectively,  gross  negligence)  or (IV) the failure of Calpine or a
          Calpine  Transaction  Party to make any  Payment  to Bear  Stearns  or

obtaining such knowledge,  inform Calpine or a Calpine  Transaction Party of (A)
its intent to preserve any claim for indemnification  under this Section 15.1(a)
with respect to such gross  negligence  and (B) the facts,  events or conditions
constituting such gross negligence, to the extent then known.

          (b) By CalBear.

               (i) Subject to Section 14.1 and the limitations set forth in this
Article XV and Article  XVII,  CalBear shall  indemnify,  save and hold harmless
Calpine,  each Calpine Transaction Party, each of their Affiliates,  and each of
their respective directors,  officers,  employees,  successors,  transferees and
assignees  (each,  a "Calpine  Party"),  from and  against  any and all  Damages
arising out of or resulting from:

                    (A) any untruth,  inaccuracy or  incorrectness  of, or other
          breach of, any  representation  or warranty of Bear Stearns or CalBear

                    (D) any Liability of Bear  Stearns,  CalBear or any of their
          Affiliates  for any  finder's  fee,  brokerage  fee or  commission  or
          similar  Payment  in  connection  with the  transactions  contemplated
          hereby and by the other Transaction Documents; or

                    (E) any violation of Applicable Law by CalBear or any of its
          Affiliates or their  respective  Representatives,  in each case to the
          extent  that the  Damages to a Calpine  Party arose out of or resulted
          from the transactions contemplated by the Transaction Documents or the
          fact that Calpine and the Calpine  Transaction  Parties are parties to
          the  Transaction  Documents;  provided  that this clause (E) shall not
          apply to any  violations of Applicable Law  indemnified  under clauses

          Transaction Documents;


                                       56


(each claim for indemnity by a Calpine Party pursuant to this Section 15.1(b), a
"Calpine  Claim");  provided  that in no event  shall  CalBear be  obligated  to
indemnify  any Calpine Party for Damages to the extent such Damages arose out of
or  resulted  from  CMSC's  performance  of or  failure  to  perform  any of its
obligations  as agent or  attorney-in-fact  for  CalBear  under the  Agency  and
Services Agreement.

               (ii) The  indemnity  provided for in this Section  15.1(b) is not
limited to Third Party Claims  against any Calpine Party,  but includes  Calpine
Claims  incurred or sustained by any Calpine Party in the absence of Third Party
Claims. With respect to any Third Party Claims against any Calpine Party covered
by the indemnity provided in this Section 15.1(b),  such  indemnification  shall
include coverage of any consequential, indirect, special, punitive, exemplary or
incidental damages included in such Third Party Claims.

               (iii) The  indemnity  provided for in this Section  15.1(b) shall

nonfulfillment, nonperformance, nonobservance or other breach or violation of or
default under, or any Misconduct related to, Soft Covenants,  for which the sole
and exclusive rights and remedies are described in Clause (a) of Section 17.3 of
this Agreement.

               (iv) The  indemnity  set forth in clauses  (A) and (B) of Section

                    (A) such  indemnity  shall not  apply to  Claims or  Damages
          constituting  Ordinary  Losses,  except to the  extent  such  Ordinary
          Losses are not consequential,  indirect, special, punitive,  exemplary
          or  incidental  Claims or Damages  and arise out of or result from (I)
          any nonfulfillment,  nonperformance,  nonobservance or other breach or
          violation of or default under Hard Covenants,  (II) Misconduct of Bear
          Stearns or CalBear or any other  matters  indemnified  in clauses  (C)
          through   (E)  above,   (III)  any   nonfulfillment,   nonperformance,
          nonobservance  or other breach or  violation  of or default  under any
          provisions  of any  Transaction  Document  arising out of or resulting
          from the gross  negligence  of Bear Stearns or CalBear  (except to the
          extent  covered  in the  definition  of  "Misconduct"  or  limited  by
          paragraph (v) below),  to the extent that such Ordinary Losses covered
          under  this  clause  (III)  incurred  in the same  Fiscal  Year in the
          aggregate  exceed $[*]  million or (IV) the failure of Bear Stearns or
          CalBear  to  make  any   Payment  to  a  Calpine   Transaction   Party
          specifically  provided  for  pursuant to the terms of the  Transaction
          Documents; and

                    (B) such  indemnity  shall not  apply to  Claims or  Damages
          constituting  Third  Party  Losses,  unless and until  such  Claims or
          Damages covered under such indemnity  incurred in the same Fiscal Year
          in the aggregate  exceed the  Threshold,  in which case such indemnity
          shall apply to all such Claims or Damages covered under such indemnity
          during such Fiscal Year whether or not the same exceed the  Threshold,
          provided that this Section 15.1(b)(iv)(B) shall not apply to Claims or
          Damages  arising  out of or  resulting  from  (I) any  nonfulfillment,
          nonperformance,  nonobservance  or other  breach  or  violation  of or

          above or (III) the  failure  of Bear  Stearns  or  CalBear to make any
          Payment  to  Calpine  or  any  of  the  Calpine   Transaction  Parties
          specifically  provided  for  pursuant to the terms of the  Transaction
          Documents.

               (v) No Calpine Party shall have the right to indemnification  for
any Ordinary  Losses  resulting  from or arising out of the gross  negligence of
Bear  Stearns or CalBear to the extent that  Calpine or any Calpine  Transaction
Party  actually  knew of such  gross  negligence  and  did not  promptly,  after
obtaining  such  knowledge,  inform Bear Stearns or CalBear of (A) its intent to
preserve any claim for  indemnification  under this Section 15.1(b) with respect
to such gross  negligence and (B) the facts,  events or conditions  constituting
such gross negligence, to the extent then known.

          (c) Defense of Claims.

               (i)  If  a  Claim  is  to  be  made  by  a  Person   entitled  to
indemnification  hereunder  (without  regard  to  any  thresholds),  the  Person
claiming such  indemnification  shall give written notice (a "Claim  Notice") to
the indemnifying  Person (A) as soon as practicable after the Person entitled to
indemnification  becomes  aware of any fact,  condition  or event which may give
rise to Damages for which  indemnification may be sought under this Section 15.1
and (B) in the case of the  assertion  of a Claim  (whether  pursuant to a legal
Action or  otherwise) or the  commencement  of any Action by a Third Party other
than directors, officers, employees, successors, transferees or assignees of, or
other  Representatives  of,  Calpine,  any  Calpine  Transaction  Party or their
Affiliates  or Bear Stearns,  CalBear or their  Affiliates  (together,  a "Third
Party Claim"), promptly upon receipt of written notice of the Third Party Claim.
The failure of any indemnified  Person to give timely notice hereunder shall not
affect rights to indemnification  hereunder,  except and only to the extent that
the indemnifying Person demonstrates actual prejudice caused by such failure.

               (ii) In the  case of a Third  Party  Claim,  if the  indemnifying
Person  shall  acknowledge  in  writing  to  the  indemnified  Person  that  the
indemnifying Person shall be obligated to indemnify the indemnified Person under
the terms of its indemnity  hereunder in connection with such Third Party Claim,
then the  indemnifying  Person shall be entitled and, if it so elects,  shall be
obligated at its own cost,  risk and expense,  to participate in or take control
of the defense and  investigation  of such Third Party Claim,  and to pursue the
defense  thereof in good faith by appropriate  actions or  proceedings  promptly
taken or  instituted  and  diligently  pursued,  including  to employ and engage
attorneys of its own choice reasonably  acceptable to the indemnified  Person to
handle and defend the same,  compromise or settle such Third Party Claim subject
to Sections 15.1(c)(iii) and 15.1(c)(iv);  provided that the indemnifying Person
shall not be entitled to take control of the defense or investigation of a Third
Party Claim, if (x) the indemnifying  Person is also a party to such Third Party
Claim and the indemnified  Person  determined in good faith,  upon the advice of
outside  counsel,  that a conflict of interest  exists  between the  indemnified
Person and the  indemnifying  Person with respect to such Third Party Claim, (y)
the indemnifying  Person fails to demonstrate to the reasonable  satisfaction of
the indemnified  Person its financial  capacity to defend such Third Party Claim


                                       58


and provide  indemnification  with respect to such Third Party Claim or (z) such
Third Party Claim is a Claim by a Governmental Authority.

               (iii) In the  event  the  indemnifying  Person  elects  to assume
control of the defense and investigation of such Third Party Claim in accordance
with  Section  15.1(c)(ii),  the  indemnified  Person  may,  at its own cost and
expense,  participate  in the  investigation,  trial,  and defense of such Third
Party Claim; provided that, if (x) the named persons to an Action resulting from
such Third Party Claim include both the indemnifying  Person and the indemnified
Person and the  indemnified  Person has been  advised in writing by counsel that
there may be one or more legal  defenses  available to such  indemnified  Person
that are different  from or additional  to those  available to the  indemnifying
person or that a conflict of interest exists between the indemnified  Person and
the  indemnifying  Person with  respect to such Third Party  Claim,  or (y) such
Third Party Claim is a Claim by a Governmental Authority, the indemnified Person
shall be entitled,  at the  indemnifying  person's  cost,  risk and expense,  to
reasonable fees and  disbursements of separate  counsel of its own choosing.  In
the event the indemnifying  Person assumes the defense of the Third Party Claim,
the indemnifying Person shall keep the indemnified Person reasonably informed of
the progress of any such defense,  compromise or  settlement.  The  indemnifying
Person shall not have the power to  compromise or settle such Third Party Claim,
except with the written consent of the indemnified  Person,  such consent not to
be unreasonably withheld or delayed (it being understood that the failure of the
indemnified Person to give such consent shall not be considered  unreasonable in
respect  of  any  compromise  or  settlement   that  (A)  does  not  include  an
unconditional  release of such indemnified  Person from all liabilities  arising
out of, or that may arise out of,  such  Third  Party  Claim or (B)  includes  a
statement as to or an admission of fault, culpability or a failure to act, by or
on behalf of such indemnified Person).

               (iv) If the  indemnifying  Person fails to notify the indemnified
Person in writing of its  election  to assume  the  defense of such Third  Party
Claim in  accordance  with this Section  15.1(c)  within ten (10)  calendar days
after  receipt  of the  Claim  Notice,  or if  the  indemnifying  person  is not
permitted  to assume the defense of such Third Party  Claim in  accordance  with
this Section  15.1(c),  the  indemnified  Person  against which such Third Party
Claim has been asserted shall have the right to undertake,  at the  indemnifying
Person's cost, risk and expense, the defense,  compromise and settlement of such
Third Party Claim on behalf of and for the account of the  indemnifying  Person;
provided  that  the  indemnifying  Person  shall  not be  liable  for  costs  of
settlement of such Third Party Claim if such Third Party Claim is compromised or
settled  without the written consent of the  indemnifying  Person (which consent
shall not be unreasonably withheld or delayed).

          (d) Loss Calculation.

          The amount of Claims or Damages to which an indemnity  provided for in
this  Section  15.1  applies  shall be  determined  after  giving  effect to all
provisions  of the  Transaction  Documents  other  than  this  Section  15.1 the
operation of which  mitigates or compensates  for such Claims or Damages (to the
extent such terms are given full force and effect),  including  (as  applicable)
any  reductions  in the Service Fee,  Service Fee Return  Refund or Bonus Amount


                                       59


payable under the Agency and Services Agreement on account or in respect of such
Claims and Damages.

   15.2   Right of Offset.  Each  Party may,  to the extent set forth in Section
3.10  hereof,  withhold and set off against any and all amounts due to any other
Party any and all amounts as to which the other Party is  obligated to indemnify
such Party pursuant to any provision of this Article XV.

   15.3   Payment.  With respect to Third Party Claims for which indemnification
is payable  hereunder,  the indemnifying  Person will pay the indemnified Person
promptly after the earlier of (a) the entry of judgment  against the indemnified
Person and the  expiration of any applicable  appeal period,  (b) the entry of a
non-appealable  judgment or final  appellate  decision  against the  indemnified
person, or (c) the execution of any settlement  agreement referred to in Section
15.1.  Notwithstanding  the foregoing,  expenses of the  indemnified  Person for
which the  indemnifying  Person is responsible  (including  reasonable  fees and
disbursements  of  counsel)  shall  be  reimbursed  on a  current  basis  by the
indemnifying Person.

   15.4   Right to  Indemnification  Not Affected by  Knowledge or  Presumption.

          (a) Except as otherwise  specifically  provided  herein,  the right to
indemnification  based upon breach of  representations,  warranties,  covenants,
agreements or obligations  will not be affected by any  investigation  conducted
with  respect to, or knowledge  acquired  (or capable of being  acquired) at any
time,  whether  before or after the execution and delivery of this  Agreement or
the Effective Date, whether as a result of disclosure by a Party hereto pursuant
to Section 11.1 or  otherwise,  with respect to the accuracy or inaccuracy of or
compliance  with any  such  representation,  warranty,  covenant,  agreement  or
obligation.

          (b) The  satisfaction of any condition based on the presumed  accuracy

that  neither  Bear  Stearns or  CalBear,  on the one hand,  nor  Calpine or the
Calpine Transaction  Parties, on the other hand, may terminate this Agreement if

Effective Date;

               (iii) by Bear  Stearns or CalBear,  upon notice to Calpine or the

the transactions  contemplated  hereby and thereby  abandoned,  immediately upon
completion of Liquidation.  The Liquidation Date shall occur and the Liquidation

               (ii) in  accordance  with  Section  16.2(d)  of  this  Agreement,

Renewal  Notice  with  respect to the end of the  Initial  Term or such  Renewal

3.14(b) by Bear Stearns,  on the one hand, or by Bear Stearns following a breach


                                       64


of Section 3.14(a) by Calpine, on the other hand, fifty (50) days after delivery
of such  Termination  Notice);  provided  that a  Termination  Notice may not be
delivered by any Party if the  Liquidation  Date has occurred or will occur as a
result of non-renewal of this Agreement or an Event of Default,  or otherwise in
accordance  with this Section  16.6(b) (and,  for the  avoidance of doubt,  if a
Liquidation  Date occurs before the end of the ninety (90) day period  following
the delivery of a Termination  Notice in accordance  with this Section  16.6(b),
Liquidation shall commence and this Agreement shall terminate in accordance with
such  Liquidation  Date and the  applicable  Termination  Notice  shall be of no
further force and effect); provided,  further, that, in the event of a breach of
Section 3.1 or Section 3.14 by Calpine or a Calpine  Transaction  Party,  on the

CalBear,  on the one hand, or Calpine or any Calpine  Transaction  Party, on the
other  hand,  may  deliver  a  Termination   Notice  pursuant  to  this  Section
16.6(b)(iii)  at any time following the Effective  Date; and provided,  further,
that if Calpine or any  Calpine  Transaction  Party,  on the one hand,  and Bear
Stearns and  CalBear,  on the other hand,  deliver  Termination  Notices to each
other nearly simultaneously (and in such a manner that it is reasonably unlikely
that  either  Termination  Notice  was  sent  following  receipt  of  the  other
Termination Notice), the Liquidation Date shall occur ninety (90) days after the
delivery of such  Termination  Notices  pursuant to Section  16.6(b)(i)  and the
Parties  shall be deemed to have  mutually  consented to the  occurrence of such
Liquidation Date;

               (iv) upon a  Calpine  Event of  Default,  if so  elected  by Bear
Stearns or CalBear;

               (v)  upon a Bear  Stearns  Event of  Default,  if so  elected  by

Calpine Transaction Party prior to such time;

               (vii)  automatically,  following a termination of any Transaction

               (i)  Conduct  of   Business   Following   Liquidation   Date  and
Termination. Immediately following the occurrence of a Liquidation Date, (1) the
Liquidation  shall commence and (2) pending  completion of the  Liquidation  and

foregoing,  as soon as practicable following the Termination Date, but not later
than ninety (90) days after such date, the Parties shall,  and shall cause their
respective  Affiliates  to,  remove and change  signage,  change and  substitute
promotional or advertising  material in whatever medium,  change  stationery and
packaging  and take all such other steps as may be required  or  appropriate  to
cease use of the CalBear Name; provided,  however, that no Party shall be deemed
to have violated this Section  16.6(c)(i) by reason of (i) the appearance of the
CalBear  Name in or on any  equipment,  manuals,  work  sheets,  risk  policies,
operating  procedures,  other written materials or other Assets of such Party or

connection with the  Transaction or CalBear's  business prior to the Termination
Date, and that generally are in the public domain,  or any other similar uses by
any such Third Party over which such Party has no  control,  or (iii) the use by
any Party or its  Affiliates  of the CalBear  Name for  purposes of conveying to

this Agreement shall  terminate,  except for (i) rights and obligations  accrued
prior to the Termination Date,  including rights and obligations with respect to

below,  the  Elective  Non-Terminating  Parties  shall  have the  right  and the
obligation  (the  "CalBear  Termination  Option"),  exercisable  within  two (2)
Business Days  following  such delivery of a Termination  Notice,  to (A) if the
Elective  Non-Terminating  Parties  are  Calpine  and  the  Calpine  Transaction
Parties, either (1) elect to acquire the Final Third Party Master Agreements, in
accordance with Section 16.6(d)(v)  (including the last sentence  thereof),  for
the amount set forth in the  applicable  Termination  Notice  (the  "Termination

Right" and either of clause (A)(2) or (B)(1),  a "Termination  Sale Right"),  in
each case  following  completion of  Liquidation.  Any Elective  Non-Terminating
Party shall exercise the CalBear  Termination  Option by delivering a notice, in
any manner provided in Section 18.2, setting forth such Elective Non-Terminating
Party's  election  to  exercise  either its  Termination  Purchase  Right or its

Termination  Parties,  within two (2) Business Days  following the occurrence of
the Liquidation  Date and in any manner provided in Section 18.2, an irrevocable

and (B) a binding  offer,  irrevocable  by its terms for two (2)  Business  Days
following  receipt  of the  Default  Termination  Notice  by the  Non-Defaulting
Termination  Parties  (the  "CalBear  Default  Option"),  (1) if the  Defaulting
Termination Parties are Calpine and the Calpine  Transaction  Parties, to either

purchase,  or any other right with  respect  to, the Final  Third  Party  Master
Agreements.  If the Defaulting  Termination Parties are Bear Stearns and CalBear

Termination  Notice,  (B) comply with their obligation to sell Final Third Party
Master  Agreements  following  exercise  of the  Default  Purchase  Right by the
Non-Defaulting  Termination  Parties, or (C) comply with their obligation to pay

following  such  failure to comply,  to purchase  for [*], the Final Third Party
Master  Agreements,  in accordance with Section  16.6(d)(v)  (including the last
sentence thereof), following the completion of Liquidation.

Purchase Right or the Default Sale Right, as applicable, the Parties responsible
for payment of the  Termination  Amount with respect to such exercise  shall pay

               (v) Obligation to Transfer  Final Third Party Master  Agreements.
The Parties  shall  cooperate  with each other and take any  actions  reasonably
necessary to cause the  consummation of the  Non-Renewal  Purchase Right and, in
the event that the Termination  Purchase Right,  the Termination Sale Right, the
Default  Purchase  Right or the  Default  Sale Right  requires a transfer of the
Final  Third  Party  Master  Agreements,  the  consummation  of the  Termination
Purchase Right,  the Termination  Sale Right,  the Default Purchase Right or the
Default Sale Right,  as  applicable,  including by  cooperating in obtaining any
applicable  Regulatory  Approvals  and any Third  Party  consents  or  releases.
Notwithstanding  anything to the contrary  contained  in this  Section  16.6(d),
CalBear  shall not be  required to transfer  any Third  Party  Master  Agreement
pursuant  to  this  Section  16.6(d)  (A)  if and  until  Calpine  or a  Calpine
Transaction  Party has paid the  Termination  Amount in accordance  with Section
16.6(d)(iv) or (B) if such Third Party Master  Agreement (1) requires consent to
transfer  from a Third  Party and such  consent  has not been  received  by Bear
Stearns within one hundred eight (180) days following the exercise by Calpine or
any of the  Calpine  Transaction  Parties  of their  right to  purchase,  or the
exercise by Bear Stearns or CalBear of their right to sell, as  applicable,  the
Final Third Party Master Agreements pursuant to this Section 16.6(d) or (2) does
not provide for the  unconditional  release of Bear  Stearns and its  Affiliates
from any  obligation to guarantee or otherwise  provide  credit  support for any
transaction under such Third Party Master Agreement,  unless such  unconditional
release of such  obligation is received by Bear Stearns within one hundred eight
(180) days  following the exercise by Calpine or any of the Calpine  Transaction
Parties of their right to  purchase,  or the exercise by Bear Stearns or CalBear
of their right to sell, as applicable,  the Final Third Party Master  Agreements
pursuant to this  Section  16.6(d).  If CalBear is not  required to transfer any
Third  Party  Master  Agreement  as a result  of clause  (B) in the  immediately
preceding  sentence,  (x) each of Bear  Stearns and CalBear  shall not, and Bear
Stearns  shall cause its  Affiliates  not to,  following the  Termination  Date,
transact any business pursuant to such Third Party Master Agreement, (y) CalBear
shall,  following the expiration of any applicable consent and/or release period
set forth in the immediately  preceding sentence,  reasonably promptly terminate
such Third Party Master Agreement in accordance with the terms thereof (provided
that  CalBear  shall not be required to  terminate  any such Third Party  Master
Agreement  in a manner that  results in Damages owed by CalBear to a Third Party
under such Third Party Master Agreement),  and (z) CalBear shall deliver written
evidence of such termination to Calpine.

               (vi) Closing of Transfer of Final Third Party Master  Agreements.
The  purchase and sale of the Final Third Party  Master  Agreements,  if any, in
accordance  with this  Section  16.6(d)  pursuant to any  exercised  Non-Renewal
Purchase Right,  Termination  Purchase Right,  Termination  Sale Right,  Default
Purchase Right or Default Sale Right, as applicable, shall take place as soon as
reasonably practicable, but in any event following the completion of Liquidation
and the receipt of any applicable  Regulatory Approvals and Third Party consents
and releases.

or, in each case, to such other place and with such other copies as any Party
may designate as to itself and its Representatives by notice to the other
Parties that are not Affiliates of such Party.

  18.3    Choice of Law; Service of Process; Venue; Jury Trial Waiver.

          (a) Each of the  Parties  agrees that this  Agreement  and each of the
other  Transaction  Documents  to which it is a party  (including  any  claim or
controversy  arising  out  of or  relating  to  this  Agreement  or  such  other
Transaction  Document)  shall be construed and interpreted and the rights of the
Parties determined in accordance with the internal laws of the State of New York
without giving effect to any choice or conflict of law  provision,  principle or
rule  (whether  of the State of New York or any other  jurisdiction)  that would
cause the  application of the laws of any  jurisdiction  other than the State of
New York. Each of the Parties irrevocably consents to the service of any and all


                                       76


process in any Action  arising out of or relating to this  Agreement,  the other
Transaction  Documents to which it is a party or the  transactions  contemplated
hereby or  thereby  by the  registered  or  certified  mailing of copies of such
process to the addresses of such Party  specified in Section  18.2.  Each of the
Parties consents and voluntarily  submits to personal  jurisdiction in the State
of New York and in the courts in such state  located in New York  County and the
United  States  District  Court  for the  Southern  District  of New York in any
proceedings arising out of or relating to this Agreement,  the other Transaction
Documents to which it is a party and the  transactions  contemplated  hereby and
thereby and,  subject to the  arbitration  provisions  set out in Section  18.4,
agrees  that all  claims  in  respect  of any such  proceeding  may be heard and
determined in any such court and that all claims  shall,  in respect of any such
proceeding, be brought, prior to appeal beyond such courts, in such courts. Each
Party  irrevocably  and  unconditionally  waives and agrees not to plead, to the
fullest  extent  permitted by law, any objection  that they may now or hereafter
have to the laying of venue or the  convenience  of the forum of any Action with
respect to this  Agreement,  the other  Transaction  Documents  to which it is a
party and the transactions contemplated hereby and thereby, in the United States
District Court for the Southern District of New York and the courts of the State
of New York located in New York County. Each Party agrees that a final judgment,
subject to appeal  rights,  in any proceeding so brought shall be conclusive and
may be  enforced  by suit on the  judgment  in any court or in any other  manner
provided by law or in equity.

          (b) Subject to the  arbitration  provisions  set out in Section  18.4,
each of the Parties agrees to commence any proceeding arising out of or relating
to this Agreement, the other Transaction Documents to which it is a party or the
transactions  contemplated hereby or thereby in the United States District Court
for the  Southern  District  of New York or the  courts of the State of New York
located in New York  County and that any  claims  shall,  in respect of any such
proceeding, initially be brought in such courts.

          (c) EACH OF THE PARTIES HERETO HEREBY  IRREVOCABLY  WAIVES ANY AND ALL
RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATED TO THIS
AGREEMENT,  THE  OTHER  TRANSACTION  DOCUMENTS  TO WHICH  IT IS A PARTY,  OR THE
TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY.

  18.4    Dispute Resolution; Arbitration.

          (a) In an effort to resolve  informally  and  amicably  any dispute or
Action that might  arise  between  the  Parties or their  respective  Affiliates
hereunder  or under  any of the other  Transaction  Documents,  Calpine  or Bear
Stearns  may by  providing  notice to the other  refer any matter in dispute for
resolution to Paul J. Posoli and Francis Dunleavy, respectively. Calpine or Bear
Stearns may change the designation of the applicable  aforementioned  individual
established  by the  previous  sentence  by notice to Bear  Stearns or  Calpine,
respectively.  If settlement  is not  thereafter  reached  through their efforts
within twenty (20) days following  such referral,  or such longer time period as
the Parties may agree,  then any Party may initiate  arbitration  proceedings as
set forth below to resolve the matter.


                                       77


          (b) Each of the Parties agrees that,  notwithstanding  anything herein
to the  contrary,  any  dispute or Action not  otherwise  resolved  pursuant  to
Section  18.4(a)  shall  be  resolved  by  binding  arbitration  proceedings  in
accordance  with this Section 18.4.  Any dispute not  otherwise  resolved may be
submitted for arbitration hereunder by any Party delivering to the other Parties
that are not its  Affiliates a notice  demanding  arbitration  of the dispute in
accordance  with the commercial  arbitration  rules of the American  Arbitration
Association  ("AAA") then in effect.  To the extent that such provisions are not
inconsistent  with such rules,  the  remaining  provisions  of this Section 18.4
shall also apply to such proceedings.

          (c) Each of  Calpine  and Bear  Stearns,  within  thirty  (30) days of
delivery of the notice demanding arbitration,  shall select an arbitrator (each,
a "Party Arbitrator"). The Party Arbitrators shall select, within ten (10) days,
one neutral arbitrator,  who shall serve as the Chairman ("Chairman")  (together
with  the  Party  Arbitrators,  the  "Arbitration  Panel").  In the  absence  of
agreement  between the Party  Arbitrators  on  selection  of the  Chairman,  the
Chairman shall be selected by the AAA.

          (d) No member of the  Arbitration  Panel may have a direct or indirect
interest in any Party or the subject of the  arbitration;  provided however that
each of Calpine and Bear Stearns may  communicate  ex parte with its  respective
Party Arbitrator, but not the Chairman.

          (e) The place of the arbitration shall be a place mutually agreed upon
by the Parties at a site chosen by the  Arbitration  Panel or, in the absence of
agreement  among  the  Arbitration  Panel,  at a site  chosen  by the  Chairman;
provided,  however,  that if the Parties are not able to mutually agree upon the
place of arbitration, such place shall be New York, New York.

          (f) The  Arbitration  Panel shall determine the rules of procedure or,
in the absence of agreement  among the Arbitration  Panel,  the Federal Rules of
Civil Procedure shall govern the procedure for discovery as well as presentation
of the  evidence.  In any event,  the  Arbitration  Panel or, in the  absence of
agreement among the  Arbitration  Panel,  the Chairman,  shall have the right to
impose reasonable restrictions on the taking of discovery, including limitations
on the number of and length of depositions of witnesses.

          (g) The Arbitration  Panel shall render a reasoned decision in writing
within  thirty (30) days of the close of evidence.  Any award issued as a result
of such  arbitration  shall be final and binding between the parties thereto and
judgment upon the award rendered by the  arbitration  panel may be entered,  and
shall be enforceable, by any Governmental Authority having jurisdiction over the
party against whom enforcement is sought.

          (h) During the course of the arbitration, each Party shall pay its and
its Affiliates' own fees,  costs and expenses  (including  attorneys'  fees) and
Calpine,  on the one hand, and Bear Stearns,  on the other hand,  shall each pay
one-half of any fees,  costs and expenses of the  Arbitration  Panel;  provided,
however that the  Arbitration  Panel shall in no way award damages for any Claim
of a type  that are not  permitted  for such  Claim  under  New York law and the
provisions of the  Transaction  Documents or that exceed the limits,  if any, on
damages  afforded  by New  York  law  and  the  provisions  of  the  Transaction
Documents, particularly Article XVII.


                                       78


          (i) Calpine and Bear  Stearns may mutually  agree,  each in their sole
discretion, to reduce any time periods specified in this Section 18.4 to resolve
any dispute or controversy on an expedited basis.

    18.5  Continued  Performance.  Each of the Parties agrees that it shall, and
shall cause each of its Affiliates that is a Party to, continue to perform under
this Agreement and the other Transaction Documents to which it is a party during
the  pendency  of  any  dispute,   arbitration  or  other  Action  hereunder  or
thereunder.  For the avoidance of doubt,  this Section 18.5 shall not prevent or
restrict the termination of, or limit the right of any Party to terminate or the
effect of the termination of, this Agreement or any other  Transaction  Document
in accordance with the terms hereof or thereof.

    18.6  Regulatory  Event.  Any  provision  of  this  Agreement  or the  other
Transaction   Documents  declared  or  rendered  unlawful  by  any  Governmental
Authority  or deemed  unlawful  because of a statutory or  regulatory  change or
interpretation  (individually  or  collectively,  such  events  referred to as a
"Regulatory  Event") will not otherwise affect the remaining lawful  obligations
that arise under this Agreement and the other Transaction Documents. Further, if
a Regulatory Event occurs, the Parties shall use their  commercially  reasonable
efforts  to modify  this  Agreement  and the  other  Transaction  Documents,  as
applicable,  in order to give effect to the original intention of the Parties in
a manner consistent with the Regulatory Event.

    18.7  Forward Contracts.  The Parties acknowledge and agree that all CalBear
Trades,  other than CalBear Trades with a maturity date less than two days after
the date the CalBear Trade is executed,  constitute  "forward  contracts" within
the meaning of the United States  Bankruptcy  Code. The Parties  acknowledge and
agree that CalBear is a "forward  contract  merchant"  within the meaning of the
United States Bankruptcy Code.

    18.8  Effectiveness;   Entire  Agreement;   Amendments  and  Waivers.   This
Agreement  shall  become  binding  upon each  Party  hereto  when such Party has
executed and delivered  this  Agreement.  This  Agreement,  and all exhibits and
schedules hereto,  constitutes the entire agreement among the Parties pertaining
to  the   subject   matter   hereof  and   supersedes   all  prior   agreements,
understandings,  negotiations and discussions,  whether oral or written,  of the
Parties; provided that the forms of agreements attached hereto as exhibits shall
be  superseded  by the copies of such  agreements  executed and delivered by the
respective parties thereto, the execution and delivery of such agreements by the
parties  thereto to be  conclusive  evidence  of such  parties'  approval of any
modification therein. Except as otherwise expressly set forth in this Agreement,
no amendment,  supplement,  waiver or other modification of this Agreement shall
be  binding  unless  agreed in  writing  by each  Party  hereto  indicating  its
intention to modify this  Agreement;  provided  that any waiver of a right under
this  Agreement  shall be binding if agreed in writing by the Party against whom
enforcement  of such waiver is sought.  Neither the failure nor any delay by any
Party in exercising  any right,  power or privilege  under this Agreement or the
other  Transaction  Documents  will  operate as a waiver of any right,  power or
privilege under this Agreement or the other Transaction Documents, and no waiver
of any of the  provisions of this Agreement or the other  Transaction  Documents
shall be deemed or shall  constitute a waiver of any other  provision  hereof or
thereof (whether or not similar),  nor shall such waiver constitute a continuing
waiver  unless  otherwise  expressly  provided in such waiver.  In addition,  no


                                       79


notice to or demand on one Party  will be deemed a waiver of any  obligation  of
such  Party or of the right of the Party  giving  such  notice or demand to take
further  action  without  notice or demand as provided in this  Agreement or the
other Transaction Documents. Notwithstanding the foregoing, (a) Bear Stearns, in
its sole  discretion,  may modify  Schedule  3.7(a) in  accordance  with Section
3.7(a), and (b) Calpine,  in its sole discretion,  may modify Schedule 3.8(a) in
accordance with Section 3.8(a).

    8.9   Multiple  Counterparts.  This Agreement may be executed in one or more
counterparts,  each of  which  shall be  deemed  an  original,  but all of which
together shall  constitute one and the same  instrument.  This Agreement and the
signature  pages  hereto may be  delivered  by telecopy or other  electronic  or
digital transmission method.

   18.10  Invalidity.  In  addition to, and  not in limitation of, Section 18.6,
in the event that any one or more of the provisions  contained in this Agreement
or in any other instrument referred to herein, shall, for any reason, be held to
be invalid,  illegal or unenforceable in any respect, then to the maximum extent
permitted by law,  such  invalidity,  illegality or  unenforceability  shall not
affect any other provision of this Agreement or any other such instrument.

    8.11  Titles; Currency;  Schedules. The  titles, captions or headings of the
Articles and Sections  herein are inserted for convenience of reference only and
are not intended to be a part of or to affect the meaning or  interpretation  of
this Agreement.  Unless otherwise  specified,  all references  contained in this
Agreement  or in any other  Transaction  Document  to  dollars  or "$" will mean
United  States  Dollars.  Disclosure  of any item in any section or part of this
Agreement or the schedules hereto will not constitute disclosure of such item in
any other section or part of this Agreement or the schedules hereto,  whether or
not the  existence of the item or its  contents  should be or is relevant to any
other section or part of this Agreement or the schedules,  unless such relevance
is reasonably apparent on its face.

   18.12  Payments. Unless otherwise  specified, all Payment due pursuant to the
terms of this Agreement shall be due by 4:00 p.m. New York City time on the date
they are due pursuant to the terms hereof.

   18.13  Publicity.  No  Party shall, and each Party shall cause its Affiliates
and  their  Representatives  not to,  issue  any  press  release  regarding  the
transactions  contemplated  hereby  or by the  other  Transaction  Documents  or
consummated  hereunder or thereunder  without the prior approval of, in the case
of Calpine or any Calpine  Transaction  Party, Bear Stearns,  and in the case of
Bear  Stearns  or  CalBear,  Calpine,  in  each  case  such  approval  not to be
unreasonably  withheld.  Notwithstanding the foregoing,  nothing herein shall be
deemed to prohibit any Party from making any disclosure  which its counsel deems
reasonably  necessary in order to fulfill such  Party's  disclosure  obligations
imposed by Applicable  Law;  provided that each such Party shall,  to the extent
reasonably  practicable,   afford,  in  the  case  of  Calpine  or  any  Calpine
Transaction  Party,  Bear  Stearns,  or in the case of Bear  Stearns or CalBear,
Calpine,  the  opportunity  to review and comment on the proposed  disclosure in
advance of such issuance;  provided,  further,  that in the event that it is not
reasonably  practicable,  such Party shall  provide Bear Stearns or Calpine,  as


                                       80


applicable, a copy promptly thereafter.  Reference is made to Section 3.5(b) for
other agreements with respect to press releases.

Party incident to or in connection with the negotiation,  preparation, execution

connection  with the  negotiation,  preparation,  execution and delivery of this
Agreement.

or  threatened  default  in, or breach  of,  any of the  terms,  conditions  and
provisions of this Agreement or the other Transaction Documents (other than Soft
Covenants),  any Party who is or is to be thereby  aggrieved will have the right
of specific  performance and injunctive relief giving effect to its rights under
this Agreement and the other  Transaction  Documents to the extent  permitted by
Applicable  Law.  Except as otherwise set forth herein,  all rights and remedies
under this Agreement and the other Transaction Documents will be cumulative, and
the exercise of one or more rights or remedies shall not prejudice or impair the
concurrent or subsequent exercise of other rights or remedies.

   18.16  Representation  of  Counsel;  Mutual Negotiation.  Each Party has been
represented  by  counsel  of its  choice in  negotiating  this  Agreement.  This
Agreement  shall therefore be deemed to have been negotiated and prepared at the
request,  direction and  construction  of each of the Parties,  at arm's length,
with the  advice  and  participation  of  counsel,  and will be  interpreted  in
accordance with its terms without favor to any Party.

Documents,  "to the  knowledge  of" or a similar  phrase  shall  mean the actual
knowledge of (i) if a specified individual or individuals are referred to in any
provision of this Agreement or any  Transaction  Documents,  such  individual or
individuals,  or (ii) if no such individual or individuals are specified, any of
the individual  Representatives of the applicable Party or its Affiliates listed
on Schedule  18.17, in each case after such  individuals  undertook a reasonable
investigation.

   18.18  No Third Party  Beneficiaries.  This  Agreement  shall be binding upon
and inure  solely to the benefit of each Party,  and nothing in this  Agreement,
express or implied,  is intended  to or shall  confer upon any other  Person any
legal or equitable right, benefit or remedy of any nature whatsoever under or by
reason  of  this  Agreement,   including  by  way  of  subrogation,   except  as
specifically set forth in Article XV hereof.


                                       81


   18.19  Time of Essence.  With regard to  all dates and time periods set forth
or referred to in this Agreement, time is of the essence.

   18.20  Force  Majeure.  In  the event of a Force  Majeure  with  respect to a
Party,  if such Party gives notice and details of the Force Majeure to the other
Party or Parties to whom  performance is owed as soon as  practicable,  then the
Party  claiming the Force Majeure shall be excused from the  performance  of its
obligations to the extent and for the period affected by the Force Majeure.  The
Party   claiming  the  Force  Majeure  shall  remedy  the  Force  Majeure  in  a
commercially reasonable manner as promptly as possible.
