      SECTION 2.6 Special Rights in Insolvency Proceedings.

            (a)   If in any Insolvency Proceeding, the holders of Senior

                  (1)   for use of cash collateral;

                  (2)   approving a debtor-in-possession financing secured by a
      Lien that is senior to or pari passu with all Senior Priority Liens upon
      any property of the estate in such Insolvency Proceeding;

                  (3)   granting any relief on account of Senior Priority Lien
      Obligations as adequate protection (or its equivalent) for the benefit of
      the holders of Senior Priority Lien Obligations in the Collateral subject
      to Senior Priority Liens; or

                  (4)   relating to a sale of assets of the Company or any other
      Obligor that provides, to the extent the assets sold are to be free and
      clear of Liens, that all Senior Priority Liens and Junior Priority Liens
      will attach to the proceeds of the sale;

then the Junior Priority Secured Parties, in their capacity as holders or
representatives of secured claims, will not oppose or otherwise contest the
entry of such order, so long as none of the Senior Priority Secured Parties in
any respect opposes or otherwise contests any request made by any Junior
Priority Secured Party for the grant to the Collateral Agent, for the benefit of
any Junior Priority Secured Parties, of a Junior Priority Lien upon any property
on which a Lien is (or is to be) granted under such order to secure the Senior
Priority Lien Obligations, co-extensive in all

                                       45
<PAGE>

respects with, but subordinated (as set forth in Section 2.5 of this Agreement,
as applicable) to, all such Senior Priority Liens on such property.

            Notwithstanding the foregoing, the Junior Priority Secured Parties
may oppose or contest any such order approving a sale of assets or bidding
procedures for any sale of assets on any grounds that may be asserted by a
holder of unsecured claims.

            (b)   The Junior Priority Secured Parties will not file or prosecute
in any Insolvency Proceeding any motion for adequate protection (or any
comparable request for relief) based upon their interest in the Collateral under
any Junior Priority Liens, except that:

                  (1)   (a) they may freely seek and obtain relief granting a
      junior Lien co-extensive in all respects with, but subordinated (as set
      forth Section 2.5 of this Agreement, as applicable) to, all Liens granted
      in the Insolvency Proceeding to, or for the benefit of, the holders of
      Senior Priority Lien Obligations; or (b) they may object to the
      confirmation of any plan of reorganization or similar dispositive
      restructuring plan that may have been filed by a party in interest and
      appear and be heard at the confirmation hearing on such plan; and

                  (2)   they may freely seek and obtain any relief upon a motion
      for adequate protection (or any comparable relief), without any condition
      or restriction whatsoever, at any time after the Discharge of Senior
      Priority Lien Obligations.

            (c)   If in any Insolvency Proceeding, debt obligations of the
reorganized debtor secured by Liens on any property of the reorganized debtor
are distributed both on account of Senior Priority Lien Obligations and on
account of Junior Priority Lien Obligations, then, to the extent that the debt
obligations distributed on account of the Senior Priority Lien Obligations and
on account of the Junior Priority Lien Obligations are secured by Liens on the
same property, the provisions of Section 2.5 of this Agreement will survive the
distribution of those debt obligations pursuant to the plan and will apply with
like effect to the Liens securing those debt obligations.

of the Secured Parties belonging to such Class. It is understood and agreed that
nothing in this Section 2.7 is intended to alter the priorities among Secured
Parties belonging to different Classes as provided in Section 2.5 hereof.

      and the First Priority Term Loan Administrative Agent, in accordance with
      the decision of more than 50% of the holders of First Priority Notes and
      First Priority Term Loans, with each such Series of Secured Debt casting
      its votes as a single block in accordance with the decision of the holders
      of such Series of Secured Debt made pursuant to the terms of the
      corresponding Secured Debt Documents; and

this Agreement, shall have the following number of votes to cast in connection
with such vote:

                  (1)   if such vote is in connection with an exercise of
      remedies, the number of votes equal to the aggregate outstanding principal
      amount of Secured Debt held by such Voting Group or Series of Secured
      Debt, as applicable (including outstanding letters of credit whether or
      not then available or drawn); and

                  (2)   if such vote is in connection with any other action, the

      Secured Debt held by such Voting Group or Series of Secured Debt, as
      applicable (including outstanding letters of credit whether or not then
      available or drawn), plus the aggregate amount of unfunded commitments to
      extend credit which, when funded, would constitute Secured Debt under such
      Voting Group or Series of Secured Debt, as applicable.

            For purposes of the foregoing, any Secured Debt registered in the
name of, or Beneficially Owned by, the Company or any Affiliate of the Company
will be deemed not to be outstanding.

            (c)   In calculating the percentage of holders of Secured Debt
consenting to, approving, waiving or otherwise providing direction with respect
to any decision hereunder, the number of votes cast in favor of such decision
shall be divided by the total number of votes entitled to be cast with respect
to such decision.

Series of Secured Debt and the Secured Debt Representative therefor may, at any

      that, in its view, such release is permitted by Section 5.1(a) and the
      respective Secured Debt Documents governing the Secured Obligations the
      holders of which such Secured Debt Representative represents;

then the Collateral Agent will execute (with such acknowledgements and/or
notarizations as are required) and deliver such release to the Company or other
applicable Obligor on or before the later of (x) the date specified in such
request for such release and (y) the fifth Business Day after the date of

release pursuant to clause (2) of Section 5.1 (a), if the terms of any such
sale, transfer or other disposition require the payment of the purchase price to
be contemporaneous with the delivery of the applicable release, then, at the
request of the Company or other applicable Obligor, the Collateral Agent will
either be present at the closing of such transaction or will deliver the release
under customary escrow arrangements that permit such contemporaneous payment and
delivery of the release.

            (d)   Each Secured Debt Representative hereby agrees that:

                  (1)   as soon as reasonably practicable after receipt of an
      Officer's Certificate from the Company pursuant to Section 5.1(b)(l) it

      statement that such release is not permitted by Section 5.1 (a) or (C) a

                                       55
<PAGE>

      after receipt of such information such Secured Debt Representative will as
      soon as reasonably practicable either provide the written confirmation or
      statement required pursuant to clause (A) or (B), as applicable; and

                  (2)   within one Business Day of the receipt by it of any
      notice from the Collateral Agent pursuant to Section 3.3. such Secured
      Debt Representative will deliver a copy of such notice to each registered
      holder of the Series of Secured Debt for which it acts as Secured Debt
      Representative.

      SECTION 5.2 Delivery of Copies to Secured Debt Representatives. The
Company will deliver to each Secured Debt Representative a copy of each
Officer's Certificate delivered to the Collateral Agent pursuant to Section 5.
l(b), together with copies of all documents delivered to the Collateral Agent
with such Officer's Certificate. The Secured Debt Representatives will not be
obligated to take notice thereof or to act thereon, subject to Section 5.1 (d).

      SECTION 5.3 Collateral Agent not Required to Serve, File or Record. The
Collateral Agent is not required to serve, file, register or record any
instrument creating, initially perfecting, or, except as otherwise set forth
herein, releasing or subordinating its security interest in any Collateral.

                  ARTICLE 6. IMMUNITIES OF THE COLLATERAL AGENT

Agreement and the other Security Documents; (ii) shall not be required to take
any action which is contrary to applicable law or any provision of this

value, validity, effectiveness, genuineness, enforceability, perfection or
sufficiency of this Agreement or any of the other Security Documents or any
other document referred to or provided for herein or therein or for any failure
by any Calpine Company or any other Person to perform any of its obligations
hereunder or thereunder; (iv) shall not be required to initiate or conduct any
litigation or collection proceedings hereunder or under any other Security
Document unless it shall have received written direction authorized by an Act of
Required Debtholders; and (v) shall not be responsible for any action taken or
omitted to be taken by it hereunder or under any other Security Document or
under any other document or instrument referred to or provided for herein or
therein in connection herewith or therewith, except for its own gross negligence
or willful misconduct.

      SECTION 6.2 Appointment of Agents and Advisors. The Collateral Agent may
execute any of the trusts or powers hereunder or perform any duties hereunder
either directly or by or through agents, attorneys, accountants, appraisers or
other experts or advisors selected by it in good faith as it may reasonably
require and will not be responsible for any misconduct or negligence on the part
of any of them.

                                       56
<PAGE>

      SECTION 6.3 Other Agreements. The Collateral Agent has accepted and is
bound by the Security Documents executed by the Collateral Agent as of the date
of this Agreement and, as directed by an Act of Required Debtholders, the
Collateral Agent may execute additional Security Documents delivered to it after
the date of this Agreement, provided, however, that such additional Security
Documents do not adversely affect the rights, privileges, benefits and
immunities of the Collateral Agent. The Collateral Agent will not otherwise be
bound by, or be held obligated by, the provisions of any credit agreement,
indenture or other agreement governing Secured Debt (other than this Agreement
and the other Security Documents).

      SECTION 6.4 Solicitation of Instructions.

            (a)   The Collateral Agent may at any time solicit and conclusively
rely upon (if relied upon in good faith) written confirmatory instructions, in
the form of an Act of Required Debtholders, an Officer's Certificate or an order
of a court of competent jurisdiction, as to any action that it may be requested
or required to take, or that it may propose to take, in the performance of any
of its obligations under this Agreement or any Security Document.

            (b)   No written direction given to the Collateral Agent by an Act
of Required Debtholders that in the sole judgment of the Collateral Agent
imposes, purports to impose or might reasonably be expected to impose upon the
Collateral Agent any obligation or liability not set forth in or arising under
this Agreement or the other Security Documents will be binding upon the
Collateral Agent unless the Collateral Agent elects, at its sole option, to
accept such direction.

      SECTION 6.5 Limitation of Liability. The Collateral Agent will not be
responsible or liable for any action taken or omitted to be taken by it
hereunder or under any other Security Document, except for its own gross
negligence, bad faith or willful misconduct as determined by a court of
competent jurisdiction.

      SECTION 6.6 Documents in Satisfactory Form. The Collateral Agent will be
entitled to require that all agreements, certificates, opinions, instruments and
other documents at any time submitted to it, including those expressly provided
for in this Agreement, be delivered to it in a form and with substantive
provisions reasonably satisfactory to it.

      SECTION 6.7 Entitled to Rely. The Collateral Agent may conclusively rely
upon any certificate, notice or other document (including any facsimile)
reasonably believed by it to be genuine and correct and to have been signed or
sent by or on behalf of the proper Person or Persons and need not investigate
any fact or matter stated in any such document. The Collateral Agent may seek
and rely upon any judicial order or judgment, upon any advice, opinion or
statement of legal counsel, independent consultants and other experts selected
by it in good faith and upon any certification, instruction, notice or other
writing delivered to it by the Company or any other Obligor in compliance with
the provisions of this Agreement or delivered to it by any Secured Debt
Representative as to the Secured Debtholders for whom it acts, without being
required to determine the authenticity thereof or the correctness of any fact
stated therein or the propriety or validity of service thereof. The Collateral
Agent may act in reliance upon any instrument comporting with the provisions of
this Agreement or any signature reasonably believed by it to be genuine and may
assume that any Person purporting to give notice or receipt

                                       57
<PAGE>

or advice or make any statement or execute any document in connection with the
provisions hereof has been duly authorized to do so. To the extent an Officer's
Certificate or an opinion of counsel is required or permitted under this
Agreement to be delivered to the Collateral Agent in respect of any matter, the
Collateral Agent may rely conclusively on such Officer's Certificate or opinion
of counsel as to such matter.

      SECTION 6.8 Secured Debt Default. The Collateral Agent will not be
required to inquire as to the occurrence or absence of any Secured Debt Default
and will not be affected by or required to act upon any notice or knowledge as
to the occurrence of any Secured Debt Default unless and until it receives a
Notice of Actionable Default.

      SECTION 6.9 Actions by Collateral Agent. As to any matter not expressly
provided for by this Agreement, the Collateral Agent will act or refrain from
acting as directed by an Act of Required Debtholders and will be fully protected
if it does so; provided, however, that the Collateral Agent shall not be
required to take any action which shall expose the Collateral Agent to personal
liability or which is contrary to this Agreement, any other Security Document or
applicable law.

      SECTION 6.10 Security or Indemnity in favor of the Collateral Agent. The
Collateral Agent will not be required to advance or expend any funds or
otherwise incur any financial liability in the performance of its duties or the
exercise of its powers or rights hereunder unless it has been provided with
security or indemnity reasonably satisfactory to it against any and all
liability or expense which may be incurred by it by reason of taking or
continuing to take such action.

      SECTION 6.11 Rights of the Collateral Agent. In the event there is any
bona fide, good faith disagreement between the other parties to this Agreement
or any of the other Security Documents resulting in adverse claims being made in
connection with Collateral held by the Collateral Agent and the terms of this
Agreement or any of the other Security Documents do not unambiguously mandate
the action the Collateral Agent is to take or not to take in connection
therewith under the circumstances then existing, or the Collateral Agent is in
doubt as to what action it is required to take or not to take hereunder, it will
be entitled to refrain from taking any action (and will incur no liability for
doing so) until directed otherwise in writing by a request signed by each
Secured Debt Representative or by order of a court of competent jurisdiction.

      SECTION 6.12 Limitations on Duty of Collateral Agent in Respect of
Collateral.

            (a)   Beyond the exercise of reasonable care in the custody of
Collateral in its possession, the Collateral Agent will have no duty as to any
Collateral in its possession or control or in the possession or control of any
agent or bailee or any income thereon or as to preservation of rights against
prior parties or any other rights pertaining thereto and the Collateral Agent
will not be responsible for filing any financing or continuation statements or
recording any documents or instruments in any public office at any time or times
or otherwise perfecting or maintaining the perfection of any security interest
in the Collateral. The Collateral Agent will be deemed to have exercised
reasonable care in the custody of the Collateral in its possession if the
Collateral is accorded treatment substantially equal to that which it accords
its own property, and the Collateral Agent will not be liable or responsible for
any loss or

                                       58
<PAGE>

diminution in the value of any of the Collateral by reason of the act or
omission of any carrier, forwarding agency or other agent or bailee selected by
the Collateral Agent in good faith.

            (b)   The Collateral Agent will not be responsible for the
existence, genuineness or value of any of the Collateral or for the validity,
perfection, priority or enforceability of the Liens in any of the Collateral,
whether impaired by operation of law or by reason of any action or omission to
act on its part hereunder, except to the extent such action or omission
constitutes gross negligence, bad faith or willful misconduct as determined by a
court of competent jurisdiction on the part of the Collateral Agent, for the
validity or sufficiency of the Collateral or any agreement or assignment
contained therein, for the validity of the title of any Obligor to the
Collateral, for insuring the Collateral or for the payment of taxes, charges,
assessments or Liens upon the Collateral or otherwise as to the maintenance of
the Collateral. The Collateral Agent hereby disclaims any representation or
warranty to the present and future holders of the Secured Obligations concerning
the perfection of the Liens and security interests granted hereunder or in the
value of any of the Collateral.

      SECTION 6.13 Assumption of Rights, Not Assumption of Duties.
Notwithstanding anything to the contrary contained herein:

                  (1)   each of the parties thereto will remain liable under
      each of the Security Documents (other than this Agreement) to the extent
      set forth therein to perform all of their respective duties and
      obligations thereunder to the same extent as if this Agreement had not be
      executed;

                  (2)   the exercise by the Collateral Agent of any of its
      rights, remedies or powers hereunder will not release such parties from
      any of their respective duties or obligations under the other Security
      Documents; and

                  (3)   the Collateral Agent will not be obligated to perform
      any of the obligations or duties of any of the parties thereunder other
      than at the Collateral Agent.

                                       59
<PAGE>

      SECTION 6.14 No Liability for Clean Up of Hazardous Materials. In the
event that the Collateral Agent is required to acquire title to an asset for any
reason, or take any managerial action of any kind in regard thereto, in order to
carry out any fiduciary or trust obligation for the benefit of another, which in
the Collateral Agent's sole discretion may cause the Collateral Agent to be
considered an "owner or operator" under any environmental laws or otherwise
cause the Collateral Agent to incur, or be exposed to, any environmental
liability or any liability under any other federal, state or local law, the
Collateral Agent reserves the right, instead of taking such action, either to
resign as Collateral Agent or to arrange for the transfer of the title or
control of the asset to a court appointed receiver. The Collateral Agent will
not be liable to any Person for any environmental liability or any environmental
claims or contribution actions under any federal, state or local law, rule or
regulation by reason of the Collateral Agent's actions and conduct as
authorized, empowered and directed hereunder or relating to any kind of
discharge or release or threatened discharge or release of any hazardous
materials into the environment.

      ARTICLE 7. RESIGNATION AND REMOVAL OF THE COLLATERAL AGENT

      SECTION 7.1 Resignation or Removal of Collateral Agent. Subject to the
appointment of a successor Collateral Agent as provided in Section 7.2 and the
acceptance of such appointment by the successor Collateral Agent:

            (a)   the Collateral Agent may resign at any time by giving not less
than 30 days' notice of resignation to each Secured Debt Representative and the
Company, and

            (b)   the Collateral Agent may be removed at any time, with or
without cause, by an Act of Required Debtholders. Upon such removal, the Company
shall promptly pay the Collateral Agent for all of its accrued and unpaid fees
and expenses incurred in accordance with this Agreement and the other Security
Documents.

      SECTION 7.2 Appointment of Successor Collateral Agent. Upon any such
resignation or removal, a successor Collateral Agent may be appointed by an Act
of Required Debtholders with, so long as no Secured Debt Default has occurred
and is continuing, the consent of the Company (which consent shall not be
unreasonably withheld). If no successor Collateral Agent has been so appointed
and accepted such appointment within 30 days after the predecessor Collateral
Agent gave notice of resignation or was removed, the retiring Collateral Agent
may (at the expense of the Company), at its option, appoint a successor
Collateral Agent, or petition a court of competent jurisdiction for appointment
of a successor Collateral Agent, which must be a bank or trust company:

            (1)   authorized to exercise corporate trust powers;

            (2)   having a combined capital and surplus of at least $50.0
      million; and

            (3)   maintaining an office in New York, New York. The Collateral
      Agent will fulfill its obligations hereunder until a successor Collateral
      Agent meeting the requirements of this Section 7.2 has accepted its
      appointment as Collateral Agent and the provisions of Section 7.3 have
      been satisfied.

                                       60
<PAGE>

      SECTION 7.3 Succession. When the Person so appointed as successor
Collateral Agent accepts such appointment:

            (1)   such Person will succeed to and become vested with all the
      rights, powers, privileges and duties of the predecessor Collateral Agent,
      and the predecessor Collateral Agent will be discharged from its duties
      and obligations hereunder; and

            (2)   the predecessor Collateral Agent will promptly transfer all
      Liens and collateral security and other property of the Trust Estates
      within its possession or control to the possession or control of the
      successor Collateral Agent and will execute instruments and assignments as
      may be necessary or desirable or reasonably requested by the successor
      Collateral Agent to transfer to the successor Collateral Agent all Liens,
      interests, rights, powers and remedies of the predecessor Collateral Agent
      in respect of the Security Documents or the Trust Estates.

Thereafter the predecessor Collateral Agent will remain entitled to enforce the
immunities granted to it in Article 6 and the provisions of Sections 8.7 and
8.8.

                  ARTICLE 8. MISCELLANEOUS PROVISIONS

      SECTION 8.1 Amendment.

            (a)   No amendment or supplement to the provisions of this Agreement
or any other Security Document (to which the Collateral Agent is a party) will
be effective without the approval of the Collateral Agent acting as directed by
an Act of Required Debtholders, except that:

                  (1)   any amendment or supplement that has the effect solely
      of adding or maintaining Collateral, securing additional Secured Debt that
      was otherwise permitted by the terms of the Secured Debt Documents to be
      secured by the Collateral or preserving or perfecting the Liens thereon or
      the rights of the Collateral Agent therein, or adding or maintaining any
      guarantee, will become effective when executed and delivered by the
      Company or any other applicable Obligor party thereto and the Collateral
      Agent;

                  (2)   no amendment or supplement that reduces, impairs or
      adversely affects the right of any Secured Debtholder (A) to vote its
      outstanding Secured Debt as to any matter described as subject to an Act
      of Required Debtholders (or amends the provisions of this clause (2) or
      the definitions of "Act of Required Debtholders" or "Actionable Default")
      (B) to share in the order of application described in Section 3.4 in the
      proceeds of enforcement of or realization on any Collateral, in each case
      that has not been released in accordance with the provisions described in
      Section 5.1, (C) to require that Liens securing Secured Obligations be
      released only as set forth in the provisions described in Section 5.1, (D)
      to enforce the rights set forth in Article 2 or (E) to vote in the manner
      set forth in Article 4 will, in the case of clauses (A) through (E),
      become effective without the consent of the requisite percentage or number
      of holders of each Series of Secured Debt so affected under the applicable
      Secured Debt Document; and

                                       61
<PAGE>

                  (3)   no amendment or supplement that imposes any obligation
      upon the Collateral Agent or any Secured Debt Representative or adversely
      affects the rights of the Collateral Agent or any Secured Debt
      Representative, respectively, in its capacity as such will become
      effective without the consent of the Collateral Agent or such Secured Debt
      Representative, respectively.

The Collateral Agent will enter into any such amendment or supplement if it has
received an Officer's Certificate to the effect that such amendment or
supplement will not result in a breach of any provision or covenant contained in
any of the Secured Debt Documents. Prior to executing any amendment or
supplement pursuant to this Section 8.1, the Collateral Agent will be entitled
to receive an opinion of counsel of the Company to the effect that the execution
of such document is authorized or permitted hereunder, and with respect to
amendments adding Collateral, an opinion of counsel of the Company addressing
customary perfection, and if such additional Collateral consists of equity
interests of any Person, priority, matters with respect to such additional
Collateral. Notwithstanding the foregoing, any amendment, supplement or other
agreement regarding the provisions of the Security Documents that releases
Collateral will be effective only in accordance with the requirements set forth
in Section 5.1.

            (b)   Unless agreed to by an Act of Required Debtholders, no
Security Document that secures Junior Priority Lien Obligations may be amended,
supplemented or otherwise modified or entered into to the extent that such
amendment, supplement or modification, or the terms of any such new Security
Document, would not be permitted under the terms of this Agreement or the Senior
Priority Debt Documents. The Junior Priority Secured Parties agree that each
Security Document that secures Junior Priority Lien Obligations (but not Senior
Priority Lien Obligations) will include the following language:

      "Notwithstanding anything herein to the contrary, the lien and security
interest granted to the Collateral Agent pursuant to this Agreement and the
exercise of any right or remedy by such Collateral Agent hereunder are subject
to the provisions of the Collateral Trust and Intercreditor Agreement, dated as
of March 23,2004 (the "Collateral Trust and Intercreditor Agreement") among
Calpine CalGen Holdings, Inc., a Delaware corporation, Calpine Generating
Company, LLC, a Delaware limited liability company, the Guarantors from time to
time party thereto, the Secured Debt Representatives from time to time party
thereto, Wilmington Trust Company (or any successor thereto or assignee thereof,
as collateral agent and each other Person which becomes a party thereto by
executing and delivering a Collateral Trust Joinder, as amended, supplemented,
amended and restated or otherwise modified and in effect from time to time. In
the event of any conflict between the terms of the Collateral Trust and
Intercreditor Agreement and this Agreement, the terms of the Collateral Trust
and Intercreditor Agreement will govern;"

provided, however, that if the jurisdiction in which any such Junior Priority
Debt Document will be filed prohibits the inclusion of the language above or
would prevent a document containing such language from being recorded, the
Junior Priority Debt Representatives and the Senior Priority Debt
Representatives agree, prior to such Junior Priority Debt Document being entered
into, to negotiate in good faith replacement language stating that the lien and
security interest granted under such Junior Priority Debt Document is subject to
the provisions of this Agreement.

      SECTION 8.2 Further Assurances.

                                       62
<PAGE>

            (a)   The Company and each of the other Obligors will do or cause to
be done all acts and things that may be required, or that the Collateral Agent
from time to time may reasonably request, to assure and confirm that the
Collateral Agent holds, for the benefit of the holders of Secured Obligations,
duly created and enforceable and perfected Liens upon the Collateral, including
after-acquired Collateral and any property or assets that become Collateral
pursuant to the definition thereof after the date hereof, subject only to such
exceptions as may be contemplated by the Secured Debt Documents. If the Company
or any other Obligor at any time acquired any real property or leasehold or
other interest in real property that is not covered by the mortgages in favor of
the Collateral Agent that are executed in connection with the issuance of the
Secured Debt, then within 45 days after such acquisition, the Company or such
Obligor will execute, deliver and record an additional mortgage or a supplement
to such mortgages, reasonably satisfactory in form and substance to the
Collateral Agent, subjecting such real property or leaseholder other interest in
real property to the Lien created by such mortgages or, if an additional
mortgage, creating Lien in favor of the Collateral Agent to secure the Secured
Obligations.

            (b)   Upon the reasonable request of the Collateral Agent or any
Secured Debt Representative at any time and from time to time, the Company and
each of the other Obligors will promptly execute, acknowledge and deliver such
security documents, instruments, certificates, notices and other documents, and
take such other actions as may be reasonably required, or that the Collateral
Agent may reasonably request, to create, perfect, protect, assure or enforce the
Liens and benefits intended to be conferred, in each case as contemplated by the
Secured Debt Documents.

            (c)   Upon the request of the Collateral Agent, the Company and the
other Obligors will permit the Collateral Agent to visit and inspect any of the
Collateral and examine and, at the Company's expense, make abstracts from any of
its books and records relating to any of the Collateral at any reasonable time
and as often as may reasonably be requested.

            (d)   The Company and the Guarantors:

                  (1)   will keep their properties adequately insured at all
      times by financially sound and reputable insurers, which, in the case of
      any insurance on any mortgaged property, are licensed to do business in
      the States where the applicable mortgaged property is located;

                  (2)   maintain such other insurance, to such extent and
      against such risks (and with such deductibles, retentions and exclusions),
      including fire and other risks insured against by extended coverage and
      coverage for acts of terrorism, as is customary with companies of the same
      or similar size engaged in the same or similar businesses operating in the
      same or similar locations, including public liability insurance against
      claims for personal injury or death or property damage occurring upon, in,
      about or in connection with the use of any properties owned, occupied or
      controlled by them;

                  (3)   maintain such other insurance as may be required by law;

                                       63
<PAGE>

                  (4)   maintain title insurance on all real property Collateral
      insuring the Collateral Agent's Lien on that property, subject only to
      liens ranking senior in priority that are permitted by each of the Secured
      Debt Documents and other exceptions to title approved by the Collateral
      Agent; provided that no title insurance need be maintained on any
      particular parcel of real property having a Fair Market Value of less than
      $5.0 million and, provided, further, that the Company and the Guarantors
      shall not be required to maintain title insurance in excess of $50.0
      million for each Facility; and

                  (5)   maintain such other insurance as may be required by the
      Security Documents.

            (e)   Upon the request of the Collateral Agent, the Company and the
Guarantors will furnish to the Collateral Agent full information as to their
property and liability insurance carriers. Holders of Secured Obligations, as a
class, will be named as additional insureds, with a waiver of subrogation, on
all insurance policies of the Company and the other Obligors and the Collateral
Agent will be named as loss payee, with 30 day notice of cancellation or
material change, on all property insurance policies of the Company and the other
Obligors.

            (f)   Without limiting the generality of the foregoing, (1) in the
event the limitations imposed by the debt instruments of Calpine and the
Obligors on the ability of the Excluded Subsidiary to be an Obligor and to grant
Liens on its property and assets to secure the Secured Obligations are at any
time no longer applicable, as determined in good faith by the Company, the
Excluded Subsidiary shall take all such actions and execute all such documents
as may be necessary to become an Obligor and to grant Liens on its property and
assets to secure the Secured Obligations, and (2) in the event the limitations
imposed by the debt instruments of Calpine and its Subsidiaries on the ability
of the Company and the Obligors to grant Liens on Expansion Assets constituting
Excluded Assets to secure the Secured Obligations are at any time no longer
applicable, as determined in good faith by the Company, such Person shall take
all such actions and execute all such documents as may be necessary to grant
Liens on such Expansion Assets to secure the Secured Obligations.

            (g)   In the event that after the date of this Agreement, a
Subsidiary of the Company is added as a Guarantor pursuant to any Secured Debt
Document, the Company shall cause such Guarantor or Guarantors to comply with
the provisions hereof and to execute a Collateral Trust Joinder and deliver such
Collateral Trust Joinder to the Collateral Agent.

      SECTION 8.3 Successors and Assigns.

            (a)   Except as provided in Section 6.2, the Collateral Agent may
not, in its capacity as such, delegate any of its duties or assign any of its
rights hereunder, and any attempted delegation or assignment of any such duties
or rights will be null and void. All obligations of the Collateral Agent
hereunder will inure to the sole and exclusive benefit of, and be enforceable
by, each Secured Debt Representative and each present and future holder of
Secured Obligations, each of whom will be entitled to enforce this Agreement as
a third party beneficiary hereof, and all of their respective successors and
assigns.

                                       64
<PAGE>

            (b)   Neither the Company nor any other Obligor may delegate any of
its duties or assign any of its rights hereunder, and any attempted delegation
or assignment of any such duties or rights will be null and void. All
obligations of the Company and the other Obligors hereunder will inure to the
sole and exclusive benefit of, and be enforceable by, the Collateral Agent, each
Secured Debt Representative and each present and future holder of Secured
Obligations, each of whom will be entitled to enforce this Agreement as a third
party beneficiary hereof, and all of their respective successors and assigns.

      SECTION 8.4 Delay and Waiver. No failure to exercise, no course of dealing
with respect to the exercise of, and no delay in exercising, any right, power or
remedy arising under this Agreement or any of the other Security Documents will
impair any such right, power or remedy or operate as a waiver thereof. No single
or partial exercise of any such right, power or remedy will preclude any other
or future exercise thereof or the exercise of any other right, power or remedy.
The remedies herein are cumulative and are not exclusive of any remedies
provided by law.

Liability to the extent such

                                       67

satisfy under applicable law to the payment and satisfaction of all Indemnified
Liabilities incurred by Indemnitees or any of them.

            (d)   No Obligor will ever assert any claim against any Indemnitee,

consequential damages or (to the fullest extent a claim for punitive damages may
lawfully be waived) any punitive damages arising out of, in connection with, or
as a result of, this Agreement or any other Secured Debt Document or any
agreement or instrument or transaction contemplated hereby or relating in any
respect to any Indemnified Liability, and each of the Obligors hereby forever
waives, releases and agrees not to sue upon any claim for any such lost profits
or special, indirect, consequential or (to the fullest extent lawful) punitive
damages, whether or not accrued and whether or not known or suspected to exist

            (e)   The agreements in this Section 8.8 will survive repayment of
all other Secured Obligations and the removal or resignation of the Collateral
Agent.

      SECTION 8.9 Severability. If any provision of this Agreement is invalid,
illegal or unenforceable in any respect or in any jurisdiction, the validity,
legality and enforceability of such provision in all other respects and of all

against any party hereto arising out of or relating to this Agreement or any of

competent jurisdiction in the State, County and City of New York. By executing

its properties, irrevocably:

                                       68
<PAGE>

            (1) accepts generally and unconditionally the nonexclusive
      jurisdiction and venue of such courts;

            (2) waives any defense of forum non conveniens;

            (3) agrees that service of all process in any such proceeding in any
      such court may be made by registered or certified mail, return receipt
      requested, to such party at its address provided in accordance with
      Section 8.5;

            (4) agrees that service as provided in clause (3) above is

      proceeding in any such court and otherwise constitutes effective and
      binding service in every respect; and

            (5) agrees each party hereto retains the right to serve process in
      any other manner permitted by law or to bring proceedings against any
      party in the courts of any other jurisdiction.

      SECTION 8.14 Waiver of Jury Trial. Each party to this Agreement waives its

purposes of the other Security Documents. The scope of this waiver is intended

Documents, including contract claims, tort claims, breach of duty claims and all
other common law and statutory claims. Each party to this Agreement acknowledges
that this waiver is a material inducement to enter into a business relationship,
that each party hereto has already relied on this waiver in entering into this
Agreement, and that each party hereto will continue to rely on this waiver in
its related future dealings. Each party hereto further warrants and represents
that it has reviewed this waiver with its legal counsel and that it knowingly
and voluntarily waives its jury trial rights following consultation with legal
counsel. This waiver is irrevocable, meaning that it may not be modified either
orally or in writing (other than by a mutual written waiver specifically

immunities and indemnities set forth in the credit agreement, indenture or other
agreement governing the applicable Secured Debt with respect to which such

             WECC FIXED PRICE GAS SALE AND POWER PURCHASE AGREEMENT
                              RECOGNITION AGREEMENT

      This Recognition Agreement (this "Agreement") is entered into as
of _______________, ____, by and between [Wilmington Trust Company] [NAME OF ANY
SUCCESSOR TO OR PERMITTED ASSIGN OF WILMINGTON TRUST COMPANY], in its capacity
as Collateral Agent under the Collateral Trust Agreement (as defined below)
(together with its successors and permitted assigns in such capacity, the
"Collateral Agent") and [Calpine Energy Services, L.P.] [ANY SUCCESSOR TO OR
PERMITTED ASSIGN OF CALPINE ENERGY SERVICES, L.P. UNDER THE WECC FIXED PRICE GAS
SALE AND POWER PURCHASE AGREEMENT] as beneficiary hereunder (the "Power
Purchaser").

                                    RECITALS

      WHEREAS, the Power Purchaser is party to that certain WECC Fixed Price Gas
Sale and Power Purchase Agreement, dated as of March 23, 2004 (the "WECC Fixed
Price PPA"), among Power Purchaser, Calpine Generating Company, LLC (the
"Company"), Delta Energy Center, LLC and Los Medanos Energy Center, LLC,
pursuant to which the Power Purchaser has agreed to provide gas to, and purchase
power from, the Company;

      WHEREAS, the Collateral Agent is party to that certain Collateral Trust
and Intercreditor Agreement, dated as of March 23, 2004 (the "Collateral Trust
Agreement"), by and among the Collateral Agent, Calpine CalGen Holdings, Inc.,
the Company, the Guarantors from time to time party thereto and the Secured Debt
Representatives from time to time party thereto under which the Collateral Agent
serves as collateral agent for the present and future holders of Secured
Obligations (as defined in the Collateral Trust Agreement) of the Company and
its Subsidiaries; and

      WHEREAS, capitalized terms used but not otherwise defined herein shall
have the meanings set forth in the Collateral Trust Agreement as of the date
hereof or as amended in accordance with the terms thereof;

      NOW, THEREFORE, the parties agree as follows:

      1.    Recognition of WECC Fixed Price PPA. Pursuant to Section 3.9 of the
Collateral Trust Agreement, the Collateral Agent, on behalf of the holders of
Secured Obligations, agrees (a) to assume, directly or indirectly (through an
Agent or Affiliate), the rights and obligations of the Company and any of its
Subsidiaries under the WECC Fixed Price PPA in the event of a foreclosure, or
the exercise or enforcement of the Collateral Agent's interests, rights, powers
and remedies in respect of the Collateral, under the Collateral Trust Agreement
or any other Security Document, and (b) not to reject the WECC Fixed Price PPA
in any Insolvency Proceeding (subject to applicable law and the discretion of
the bankruptcy court), in each case so long as the Power Purchaser (or its
successor or permitted assignee under the WECC Fixed Price PPA) is

                                    EXHIBIT B

<PAGE>

not in default under the WECC Fixed Price PPA or the Index Based Gas Sale and
Power Purchase Agreement.

      2.    Subsequent Owners. The Collateral Agent further agrees, on behalf of
the holders of Secured Obligations, that any sale of [INSERT NAME OF PROJECTS
SERVICING WECC FIXED PRICE PPA] (the "Project") shall be expressly subject to
the rights and obligations of Power Purchaser under this Agreement. Each
subsequent owner of the Project, including, as applicable, the Collateral Agent
by virtue of foreclosure of its Lien on the Project, shall succeed to the
obligations of the Collateral Agent and the holders of Secured Obligations
hereunder. Each subsequent owner of the Project shall assume such obligations
and shall take all actions reasonably necessary to cure any existing defaults
hereunder that are capable of being cured, including, in the event that the WECC
Fixed Price PPA has been rejected, avoided or otherwise terminated in violation
of this Agreement, by entering into a replacement agreement with the Power
Purchaser (or its successor or permitted assignee under the WECC Fixed Price
PPA) on terms that are no less advantageous to the Power Purchaser (or its
successor or permitted assignee under the WECC Fixed Price PPA).

      3.    Severability. If any provision of this Agreement is invalid, illegal
or unenforceable in any respect or in any jurisdiction, the validity, legality
and enforceability of such provision in all other respects and of all remaining
provisions, and of such provision in all other jurisdictions, will not in any
way be affected or impaired thereby.

      4.    Headings. Section headings herein have been inserted for convenience
of reference only, are not to be considered a part of this Agreement and will in
no way modify or restrict any of the terms or provisions hereof.

      5.    Governing Law. The internal law of the State of New York will govern
and be used to construe this Agreement without giving effect to applicable
principles of conflicts of law to the extent that the application of the laws of
another jurisdiction would be required thereby.

      6.    Further Assurances. Whenever requested to do so by the other party,
each party hereto shall execute, acknowledge and deliver any further
conveyances, assignments, confirmations, satisfactions, releases, powers of
attorney, instruments of further assurance, approvals, consents and any further
instruments or documents that are necessary, expedient or proper to complete any
conveyances, transfers, sales and assignments contemplated by this Agreement. In
addition, each party hereto shall do any other acts and execute, acknowledge and
deliver any requested documents in order to carry out the intent and purpose of
this Agreement.

      7.    Successors and Assigns. This Agreement shall be binding upon, and
inure to the benefit of, both parties and their respective successors and
assigns.

      8.    Counterparts. This Agreement may be executed in any number of
counterparts, each of which when so executed and delivered will be deemed an
original, but all such counterparts together will constitute but one and the
same instrument.

      "Insolvency Proceeding" has the meaning given such term in the Collateral
Trust Agreement.

      "Fair Market Value" means the fair market value of the asset or property

      2.    Interests of Lenders. Facility Owner may, without the prior consent
of any other Party, assign its rights and interests in and to the Shared
Facilities and under the Shared Facilities Agreement to Collateral Agent and to
any lender or lenders refinancing the debt under the Secured Debt Documents, and
Expansion Owner may, without the prior consent of any other Party, assign its
rights and interests in and to the Shared Facilities and under the Shared
Facilities

<PAGE>

Agreement to Expansion Lender and to any lender or lenders refinancing the debt
under the Expansion Loan Agreement. Each Party agrees to cooperate with the
other Parties in good faith to execute such consents to assignment as may
reasonably be requested by any Party hereto or its successors or assigns
(including any refinancing lenders, as applicable), provided that the rights and
obligations of the Parties hereunder, under the Shared Facilities Agreement or
in and to the Shared Facilities shall not be modified or impaired by such
consent other than in connection with granting such lender reasonable cure
rights and other customary lender protective provisions.

      3.    Recognition of Shared Facilities Agreement. Each of the Parties
hereby acknowledges, recognizes and consents to the Shared Facilities Agreement
and the rights and obligations of the respective parties thereto under the
Shared Facilities Agreement and agrees that such Party's ownership of or
interest in the Facility or the Expansion Assets, as the case may be, is subject
to the rights and interests of the other Parties in and to the Shared Facilities
under the Shared Facilities Agreement.

      4.    Subsequent Owners. All sales of the Projects shall be expressly
subject to the rights and obligations of the Parties hereunder and under the
Shared Facilities Agreement. Each subsequent owner of the Facility and the
Expansion Assets, including, as applicable, Collateral Agent by virtue of
foreclosure of its lien on the Facility and Expansion Lender by virtue of
foreclosure of its lien on the Expansion Assets, shall succeed to the rights and
obligations of Facility Owner or Expansion Owner, as applicable, in and to the
Shared Facilities, including all rights and obligations under the Shared
Facilities Agreement. Each subsequent owner of the Facility and the Expansion
Assets shall assume (in the case of the Collateral Agent, directly or indirectly
through any agent or Affiliate) the rights and obligations of the owner of such
property, as applicable, under the Shared Facilities Agreement and shall cure
any existing defaults under the Shared Facilities Agreement by the Party to
whose interest it succeeded that are capable of being cured.

      5.    Subordination of Lender's Interests. Each of Collateral Agent and
Expansion Lender each hereby intentionally and unconditionally subordinate their
respective rights under the Secured Debt Documents and the Expansion Loan
Agreement, as applicable, and all Related Security Documents, with respect to
the Shared Facilities and under the Shared Facilities Agreement, to the rights
and interests of the Parties in and to the Shared Facilities and under the
Shared Facilities Agreement, including all renewals, modifications, replacements
and extensions thereof. The Shared Facilities Agreement and the rights and
obligations of the Parties thereunder and in and to the Shared Facilities shall
not be affected by and shall survive a foreclosure of any Related Security
Document. Subject to the foregoing, nothing herein shall affect, hinder or
impair (i) the right of Collateral Agent to exercise any of its rights or
remedies under the Secured Debt Documents or the Related Security Documents or
(ii) the right of Expansion Lender to exercise any of its rights or remedies
under the Expansion Loan Agreement or the Related Security Documents.

      6.    Right To Cure Defaults. Each Lender shall have the right, but not
the obligation, to cure any or all defaults of a Party to, or in respect of the
Project on which such Lender has a lien under, the Shared Facilities Agreement.
In the event of a default by Facility Owner or Expansion Owner under the Shared
Facility Agreement (such party being the "Defaulting

<PAGE>

Party"), the other party (the "Non-Defaulting Party") shall give written notice
of such default to the Defaulting Party's Lender, and such Lender shall have a
period of thirty (30) days, in the case of a default resulting from the failure
to pay any amounts due and owing, or ninety (90) days, in the case of other
defaults, after receipt of such notice to cure such default; provided, however,
that if such non-monetary default cannot reasonably be cured in such ninety (90)
day period, the Defaulting Party's Lender shall have such additional period of
time not to exceed an additional one hundred eighty (180) days as may reasonably
be necessary to cure such default, including time to acquire possession or
control of the Facility or the Expansion Assets, as applicable, if (i) the
default is reasonably capable of being cured, (ii) such Lender commences such
cure promptly within such ninety (90) day period and thereafter diligently
prosecutes such cure to completion, and (iii) the failure to complete such cure
within such ninety (90) day period does not have and would not reasonably be
expected to have a material adverse effect on the Non-Defaulting Party or the
Project owned by the Non-Defaulting Party.

      7.    Rights If Project Is Dismantled.

      (a)   Each Party hereto agrees that, in the event it elects to dismantle
or otherwise break up its Project or the Project on which it has a lien, it will
first offer to the Project Owner of the other Project and its Lender the right
to purchase any portion of such Project that may comprise, be a part of or be
necessary for the use, operation or maintenance of the Shared Facilities (with
respect to the Project being dismantled or broken up, the "Related Assets") at
the Fair Market Value of such property or asset. Prior to dismantling or
breaking up the Project, the Project Owner or its Lender shall give the Project
Owner of the other Project and its Lender written notice thereof and shall, in
such notice, offer to sell the Related Assets to such Project Owner and its
Lender. Such Project Owner and its Lender shall have a reasonable period of
time, but not less than ninety (90) days, after receipt of such notice to decide
whether or not it will exercise such right to purchase the Related Assets and
shall notify the Project Owner of the Project to be dismantled or broken up and
its lender in writing of its decision within such period. Any such offer, once
accepted, shall be binding on all applicable Parties. Any dispute regarding the
Fair Market Value of the Related Assets shall be resolved by arbitration in
accordance with the then applicable Commercial Arbitration Rules of the American
Arbitration Association at an arbitration held in the city nearest the Facility
and the Expansion Assets in which the American Arbitration Association has an
office, or in such other location as the Parties may agree.

      (b)   Without limiting any Party's rights under Section 7(a) above, if a
Project Owner or its Lender desires to sell any Related Assets, any such sale to
a third party shall be subject to a right of first refusal in favor of the other
Project Owner, who shall have the right to purchase such Related Assets for the
same price and on the same terms as the prospective purchaser thereof; provided,
however, that if the prospective purchaser of such Related Assets proposes to
pay any portion of such purchase price by a note or other extension of credit
supported by a guarantee, letter of credit or other credit support, the other
Project Owner shall have the right to substitute a guarantee or letter of credit
from another party with the same or better credit rating or to pay such amount
in cash. Upon agreement with a prospective purchaser on the terms and conditions
of the purchase and sale of the Related Assets, the selling Project Owner shall
offer in writing to sell such Related Assets to the other Project Owner for the
same price and on the same terms as agreed with the prospective purchaser
thereof. The other Project Owner (or its Lender

<PAGE>

acting on its behalf) shall have the right to purchase such Related Assets on
such terms and conditions (including the proviso to the second preceding
sentence), free and clear of any claims of the selling Project Owner, its Lender
or the prospective purchaser. If the other Project Owner (or its Lender acting
on its behalf) elects to exercise such right of first refusal, it shall so
notify the selling Project Owner in writing within ninety (90) days after
receipt of the written offer from the selling Project Owner. Failure to so
notify the selling Project Owner within such ninety (90) day period shall be
considered a rejection of such offer by the other Project Owner. Any and all
offers or agreements by the selling Project Owner to sell any Related Assets to
a third party shall be subject to the right of refusal set forth in this Section
7(b), whether or not it is so stated in the offer or agreement to sell such
Related Assets.

      8.    Insolvency Proceedings.

      (a)   In the event of an Insolvency Proceeding with respect to any Party
hereto, none of the other Parties will take any action in such Insolvency
Proceeding to reject, terminate or otherwise set aside this Agreement or the
Shared Facilities Agreement or to hinder, impair or contest the rights of any
Party under this Agreement or the Shared Facilities Agreement, the validity or
priority of any liens or security interests securing a Party's rights under this
Agreement or the Shared Facilities Agreement or the exercise of remedies by any
Party to enforce its rights under this Agreement or the Shared Facilities
Agreement.

      (b)   In the event that this Agreement or the Shared Facilities Agreement
is rejected by a trustee or debtor-in-possession in any Insolvency Proceeding,
and if, within forty-five (45) days after any other Party hereto (or their
respective successors or assigns or any person or entity claiming under or
through such Party) acquires sufficient title to the interests in the Shared
Facilities previously held by the Party that rejected this Agreement or the
Shared Facilities Agreement, any other Party hereto shall so request, each Party
hereto (or their respective successors and assigns, as applicable) will execute,
deliver and record (if applicable) new agreements on the same terms and
conditions as this Agreement and/or the Shared Facilities Agreement, as
applicable, for the remaining term of such agreement before giving effect to
such termination.

      9.    Specific Enforcement. Each Party hereto agrees that the rights and
obligations under this Agreement and under the Shared Facilities Agreement are
unique and that they may be specifically enforced, regardless of the
availability or potential availability of other remedies. Without limiting the
generality of the foregoing, each Party expressly waives the adequacy of a
remedy at law as a defense or objection to specific enforcement of this
Agreement or of the Shared Facilities Agreement.

      10.   Further Assurances. Each Party agrees to cooperate with the other
Parties in good faith and to execute and deliver all further instruments and
documents and to take all further actions as may reasonably be necessary to
implement this Agreement or to carry out the intent of the Parties hereunder.

      11.   Successors and Assigns. Except as otherwise provided herein, no
Party may assign its rights or interests hereunder without the prior written
consent of the other Parties;

<PAGE>

provided, however, that any party may assign its rights and interests hereunder
to an Affiliate of such Party that succeeds to all of the assigning Party's
interests in the applicable Project (or, in the case of the Collateral Agent, to
any agent or to any successor or assign permitted under the Collateral Trust
Agreement), so long as such assignee assumes all of the assignor's rights and
obligations under this Agreement and the Shared Facilities Agreement. Subject to
the foregoing, this Agreement shall bind and benefit the successors and assigns
of each of the Parties.

      12.   Notices. All notices required or permitted hereunder shall be given
in writing and shall be delivered to the Party or Parties to which it is
addressed by hand, by private courier or by first class United States mail,
postage prepaid, at the following addresses or such other addresses as any Party
may designate by like notice.

                            [INSERT NOTICE ADDRESSES]

      13.   Amendments. No amendment or modification of this Agreement shall be
valid or binding on the Parties unless such amendment or modification is in
writing and is executed by each of the Parties affected thereby.

      14.   Governing Law. This Agreement shall be governed by the laws of the
State of [INSERT STATE IN WHICH FACILITY AND EXPANSION ASSETS ARE LOCATED].

      15.   Waiver of Consequential Damages. Notwithstanding anything herein to
the contrary, no Party or its Affiliates shall be liable to any other Party or
its Affiliates for any consequential, incidental, special, indirect, exemplary
or punitive damages of any nature, whether sought in contract or in tort and
regardless of rules relating to strict liability, comparative or contributory
negligence, or intentional or willful misconduct.

      16.   Memorandum. The Parties agree to execute and acknowledge a
memorandum of this Agreement in recordable form that may be recorded by any
Party in the [Official Records] of [INSERT COUNTY AND STATE OR OTHER APPROPRIATE
REFERENCE].

      IN WITNESS WHEREOF, THE Parties have executed this Agreement as of the day
and year first above written.

the Collateral Agent, its successors and assigns, for the benefit of the
Collateral Agent and the Third Priority Secured Parties, a security interest in

to Pledgor (provided that if an Insolvency Proceeding shall have occurred with
respect to Pledgor, such written notice shall not be required and shall be
deemed to have been received by Pledgor upon the occurrence of such Event of
Default), Pledgor shall be entitled to exercise all voting and other rights with
respect to the Pledged Collateral; provided, however, that no vote shall be
cast, right exercised or other action taken which would result in any violation
of any provision of this Agreement or any other Secured Debt Document.

                                       6
<PAGE>

            (ii)  Upon the occurrence and during the continuation of an Event of
Default and upon written notice from the Collateral Agent to Pledgor (provided
that if an Insolvency Proceeding shall have occurred with respect to Pledgor,
such written notice shall not be required and shall be deemed to have been
received by Pledgor upon the occurrence of such Event of Default), all voting
and other rights of Pledgor with respect to the Pledged Collateral which Pledgor
would otherwise be entitled to exercise pursuant to the terms of this Agreement
or otherwise shall cease, and all such rights shall be vested in the Collateral
Agent which shall thereupon have the sole right to exercise such rights. After
all Events of Default have been cured or waived and Pledgor has delivered to the
Collateral Agent a certificate to that effect, Pledgor's rights under this
Section 2.3 shall be reinstated.

      (b)   Distributions.

            (i)   Unless an Event of Default shall have occurred and be
continuing and written notice shall have been provided by the Collateral Agent
to Pledgor (provided that if an Insolvency Proceeding shall have occurred with
respect to Pledgor, such written notice shall not be required and shall be
deemed to have been received by Pledgor upon the occurrence of such Event of
Default), Pledgor shall be entitled to receive and retain any and all dividends,
interest, principal and other distributions paid on or distributed in respect of
the Pledged Collateral to the extent and only to the extent that all such
dividends, interest, principal and other distributions are permitted by, and
otherwise paid or distributed in accordance with, the terms and conditions of
the Secured Debt Documents.

            (ii)  Upon the occurrence and during the continuation of an Event of
Default and upon written notice from the Collateral Agent to Pledgor (provided
that if an Insolvency Proceeding shall have occurred with respect to Pledgor,
such written notice shall not be required and shall be deemed to have been
received by Pledgor upon the occurrence of such Event of Default), all rights of
Pledgor to the dividends, interest, principal and other distributions shall
cease and all such rights shall be vested in the Collateral Agent which shall
thereupon have the sole right to receive such distributions. After all Events of
Defaults have been cured or waived and Pledgor has delivered to the Collateral
Agent a certificate to that effect, Pledgor's rights under this Section 2.3
shall be reinstated.

      (c)   Turnover. All distributions and other amounts which are received by
Pledgor contrary to the provisions of this Agreement shall be received in trust
for the benefit of the Collateral Agent, shall be segregated from other funds of
Pledgor and shall be forthwith paid over to the Collateral Agent as Pledged
Collateral in the same form as so received (with any necessary endorsement
requested by Collateral Agent).

      Section 2.4 Collateral Agent Not Liable. Notwithstanding any other
provision contained in this Agreement, Pledgor shall remain liable under the LLC
Agreement to observe and perform all of the conditions and obligations to be
observed and performed by Pledgor thereunder. The powers conferred on the
Collateral Agent hereunder are solely to protect its interest in the Pledged
Collateral and the interests of the Secured Parties and shall not impose any
duty upon it to exercise any such powers. Neither the Collateral Agent, its
Affiliates nor any of their directors, officers, employees, Affiliates or agents
shall be liable for acting in any way hereunder, for failure to demand, collect
or realize upon all or any part of the Pledged Collateral

                                       7
<PAGE>

or for any delay in doing so or shall be under any obligation to sell or
otherwise dispose of any Pledged Collateral upon the request of Pledgor or
otherwise.

      Section 2.5 Attorney-in-Fact. Pledgor hereby appoints the Collateral
Agent, on behalf of the Secured Parties, as its true and lawful attorney-in-fact
and proxy, with full power and authority in the place and stead of Pledgor and
in the name of Pledgor or in its own name, at Pledgor's cost and expense, to the
extent reasonable, from time to time to take any action and to execute any
instrument which may be reasonably necessary to enforce its rights under this
Agreement, including, without limitation, authority to receive, endorse and
collect all instruments made payable to Pledgor representing any distribution,
interest payment or other payment in respect of the Pledged Collateral or any
part thereof to be paid over to the Collateral Agent pursuant to Sections 2.3(b)
and (c) and to give full discharge for the same.

      Section 2.6 Collateral Agent May Perform. If Pledgor fails to perform any
agreement contained herein after receipt of a written request to do so from the
Collateral Agent, the Collateral Agent may (but shall not be obligated to)
itself perform, or cause performance of, such agreement, and the expenses of the
Collateral Agent, including the reasonable fees and expenses of its counsel,
incurred in connection therewith shall be payable by the Company under Section
8.7 of the Collateral Trust Agreement; provided that if an Insolvency Proceeding
shall have occurred with respect to Pledgor, the written request described in
this Section 2.6 shall not be required and shall be deemed to have been received
by Pledgor upon the failure of Pledgor to perform such agreement.

      Section 2.7 Reasonable Care. The Collateral Agent shall be deemed to have
exercised reasonable care in the custody and preservation of the Pledged
Collateral in its possession if the Pledged Collateral is accorded treatment
substantially equivalent to that which the Collateral Agent accords its own
property of the type of which the Pledged Collateral consists, it being
understood that the Collateral Agent shall have no responsibility for (a)
ascertaining or taking action with respect to calls, conversions, exchanges,
maturities, tenders or other matters relative to any Pledged Collateral, whether
or not the Collateral Agent has or is deemed to have knowledge of such matters,
or (b) taking any necessary steps to preserve rights against any parties with
respect to any Pledged Collateral.

      Section 2.8 Security Interest Absolute. All rights and security interests
of the Collateral Agent purported to be granted hereunder, and all obligations
of Pledgor hereunder, shall be absolute and unconditional irrespective of:

      (a)   any lack of validity or enforceability of any of the Secured Debt
Documents or any other agreement or instrument relating thereto;

      (b)   any change in the time, manner or place of payment of, or in any
other term of, all or any of the Secured Obligations, or any other amendment or
waiver of or any consent to any departure from the Secured Debt Documents or any
other agreement or instrument relating thereto;

                                       8
<PAGE>

      (c)   any exchange, release or non-perfection of any other collateral, or
any release, amendment or waiver of, or consent to any departure from, any
guaranty, for all or any of the Secured Obligations; or

      (d)   any other circumstance which might otherwise constitute a defense
available to, or a discharge of, Pledgor.

                                   ARTICLE 3.
                         REPRESENTATIONS AND WARRANTIES

            Pledgor represents and warrants to the Collateral Agent for its
benefit and the benefit of the Secured Parties, as of the Closing Date, as

delivery of this Agreement:

existing corporation in good standing under the laws of the State of Delaware,
with corporate power and authority to execute, deliver and perform this
Agreement and to own or lease its properties and conduct its business in such
jurisdiction; and Pledgor is duly qualified to do business as a foreign limited
liability company, and is in good standing in, all other jurisdictions in which
its ownership or lease of property or the conduct of its business requires such
qualification.

      Section 3.2 Authorization. This Agreement has been duly authorized and
validly executed and delivered by Pledgor and constitutes a valid and legally
binding obligation of Pledgor, enforceable against Pledgor in accordance with
its terms, subject to bankruptcy, insolvency, fraudulent transfer,
reorganization, moratorium and similar laws of general applicability relating to
or affecting creditors' rights and to general equity principles.

      Section 3.3 Compliance with Law. The execution, delivery and performance
of this Agreement by Pledgor, the grant and perfection of the security interests
hereunder, compliance with the terms and provisions of this Agreement by
Pledgor, and the consummation by Pledgor of the transactions contemplated herein
and therein will not result in a breach or violation of any of the terms and
provisions of, or conflict with or constitute a default under, or result in the
imposition or creation of (or the obligation to create or impose) a Lien (other
than in favor of the Secured Parties) under, any statute, rule, regulation or
order of any governmental agency or body or any court, domestic or foreign,
having jurisdiction over Pledgor, the Company, any of their Subsidiaries or any
of their respective properties, or any agreement or instrument to which any of
such Persons is a party or by which any of such Persons is bound or to which any
of the properties of any of such Persons is subject, or the organizational
documents of any of such Persons.

      Section 3.4 Valid Security Interest. When UCC financing statements naming
Pledgor as "debtor" and Collateral Agent as "secured party" and describing the
Pledged Collateral are filed in the appropriate filing offices, this Agreement
will create a perfected security interest in all right, title and interest of
Pledgor in the Pledged Collateral, to the extent perfection can be obtained by
filing UCC financing statements in such jurisdictions. When Pledged Collateral
constituting certificated securities (as defined in the UCC) is delivered to the
Collateral Agent, together with instruments of transfer duly endorsed in blank,
this Agreement will create a

                                       9

perfected security interest in all right, title and interest of Pledgor in such
certificated securities to the extent perfection is governed by the UCC as in
effect in any applicable jurisdiction.

interest in the Pledged Collateral free from any Liens other than the Liens
created pursuant to this Agreement and other Permitted Liens.

Collateral pursuant to this Agreement or for the due execution, delivery or
performance of this Agreement by Pledgor, or for the exercise by the Collateral

authorizations and orders as would not, in the aggregate, have a material
adverse effect on the condition (financial or other), business, properties or
results of operations of the Company and its Subsidiaries taken as a whole, or
materially affect the aggregate value of the Collateral.

                                   ARTICLE 4.
                                   COVENANTS

            Pledgor hereby covenants and agrees from and after the date of this
Agreement until the termination of this Agreement in accordance with the
provisions of Section 6.3 hereof:

      Section 4.1 Chief Executive Office. Pledgor shall not establish a new
location for its chief executive office, change its state of incorporation or
change its name until (i) it has given to the Collateral Agent not less than
thirty (30) days prior written notice of its intention so to do, clearly
describing such new location or specifying such new state or name, as the case
may be, and (ii) with respect to such new location or such new state or name, as
the case may be, it shall have taken all action necessary to maintain the
security interest of the Collateral Agent in the

                                       10
<PAGE>

Pledged Collateral intended to be granted hereby at all times fully perfected
and in full force and effect.

      Section 4.2 Supplements: Further Assurances, etc. Pledgor shall at any
time and from time to time, at the expense of Pledgor, promptly execute and
deliver all further instruments and documents, and take all further action, that
the Collateral Agent may reasonably request, in order to perfect any security
interest granted or purported to be granted hereby in the Pledged Collateral or
to enable the Collateral Agent to exercise and enforce its rights and remedies
hereunder with respect to any Pledged Collateral.

      Section 4.3 Amendment of LLC Agreement. Pledgor shall not, without the
prior written consent of the Collateral Agent, agree to or permit (a) the
cancellation or termination of the LLC Agreement, except upon the expiration of
the stated term thereof, or (b) any amendment, supplement or modification of, or
waiver with respect to any of the provisions of, the LLC Agreement, in either
case, that is prohibited by the Secured Debt Documents; provided, that Pledgor
agrees that it shall not, without the prior written consent of the Collateral
Agent, amend or modify the LLC Agreement in any manner which would expressly
restrict the Collateral Agent's ability to exercise remedies in respect of the
Pledged Collateral as and to the extent contemplated hereby.

      Section 4.4 Certification of Equity Interests. The Equity Interests in the
Company pledged hereunder shall be "certificated securities" under the UCC.

      Section 4.5 Certificates and Instruments. Pledgor shall deliver all
certificates or other instruments representing the Pledged Collateral to the
Collateral Agent with all necessary instruments of transfer or assignment duly
indorsed in blank. In the event Pledgor obtains possession of any certificates,
or any securities or instruments forming a part of the Pledged Collateral,
Pledgor shall promptly deliver the same to the Collateral Agent together with
all necessary instruments of transfer or assignment duly indorsed in blank.
Prior to any such delivery, any Pledged Collateral in Pledgor's possession shall
be held by Pledgor in trust for the Collateral Agent.

      Section 4.6 Bankruptcy. Pledgor shall not authorize or permit the Company
to (a) commence a voluntary case or other proceeding seeking liquidation,
reorganization or other relief with respect to the Company or the Company's
debts under any Bankruptcy Law now or hereafter in effect or seeking the
appointment of a trustee, receiver, liquidator, custodian or other similar
official of the Company or any substantial part of the Company's property, (b)
consent to any such relief or to the appointment of or taking possession by any
such official in an involuntary case or other proceeding commenced against the
Company or (c) make a general assignment for the benefit of the Company's
creditors. Pledgor shall not commence or join with any other Person (other than
the Collateral Agent and the other Secured Parties) in commencing any proceeding
against the Company under any Bankruptcy Law or any similar statute now or
hereafter in effect in any jurisdiction.

                  EXERCISE OF REMEDIES UPON AN EVENT OF DEFAULT

      Section 5.1 Remedies Generally. If an Event of Default shall have occurred
and be continuing, the Collateral Agent may exercise in respect of the Pledged
Collateral, in addition to all other rights and remedies granted in this
Agreement and in any other instrument or agreement securing, evidencing or
relating to the Secured Obligations, all rights and remedies of a secured party
under the UCC and all other rights and remedies available at law or in equity,
in each case subject to and in accordance with the Collateral Trust Agreement.

      Section 5.2 Sale of Pledged Collateral

      (a)   Without limiting the generality of Section 5.1, if an Event of
Default shall have occurred and be continuing, the Collateral Agent may, without
notice except as specified below, sell the Pledged Collateral or any part
thereof in one or more parcels at public or private sale or at any of the
Collateral Agent's corporate trust offices or elsewhere, for cash, on credit or
for future delivery, and at such price or prices and upon such other terms as
are commercially reasonable, irrespective of the impact of any such sales on the
market price of the Pledged Collateral at any such sale. Each purchaser at any
such sale shall hold the property sold absolutely, free from any claim or right
on the part of Pledgor, and Pledgor hereby waives (to the extent permitted by
law) all rights of redemption, stay and/or appraisal which it now has or may at
any time in the future have under any rule of law or statute now existing or
hereafter enacted. Pledgor agrees that at least ten (10) days notice to Pledgor
of the time and place of any public sale or the time after which any private
sale is to be made shall constitute reasonable notification. The Collateral
Agent shall not be obligated to make any sale of Pledged Collateral regardless
of notice of sale having been given. The Collateral Agent may adjourn any public
or private sale from time to time by announcement at the time and place fixed
therefor, and such sale may, without further notice, be made at the time and
place to which it was so adjourned. The Collateral Agent shall incur no
liability as a result of the sale of the Pledged Collateral, or any part
thereof, at any public or private sale. Pledgor hereby waives any claims against
the Collateral Agent arising by reason of the fact that the price at which any
Pledged Collateral may have been sold at such a private sale, if commercially
reasonable, was less than the price which might have been obtained at a public
sale, even if the Collateral Agent accepts the first offer received and does not
offer the Pledged Collateral to more than one offeree.

      (b)   Pledgor recognizes that, if an Event of Default shall have occurred
and be continuing, the Collateral Agent may elect to sell all or any part of the
Pledged Collateral to one or more purchasers in privately negotiated
transactions in which the purchasers will be obligated to agree, among other
things, to acquire the Pledged Collateral for their own account, for investment
and not with a view to the distribution or resale thereof. Pledgor acknowledges
that any such private sales may be at prices and on terms less favorable than
those obtainable through a public sale (including, without limitation, a public
offering made pursuant to a registration statement under the Securities Act),
and Pledgor and the Collateral Agent agree that such private sales shall be made
in a commercially reasonable manner and that the Collateral Agent has no
obligation to engage in public sales and no obligation to delay sale of any
Pledged Collateral to permit the issuer thereof to register the Pledged
Collateral for a form of public sale requiring registration under the Securities
Act. If the Collateral Agent determines to exercise its right to

                                       12
<PAGE>

sell any or all of the Pledged Collateral, upon written request Pledgor shall,
from time to time, furnish to the Collateral Agent all such information as is
necessary in order to determine the number of shares and other instruments
included in the Pledged Collateral which may be sold by the Collateral Agent as
exempt transactions under the Securities Act and rules of the SEC thereunder, as
the same are from time to time in effect.

      Section 5.3 Purchase of Pledged Collateral. The Collateral Agent may be a
purchaser of the Pledged Collateral or any part thereof or any right or interest
therein at any sale thereof, whether pursuant to foreclosure, power of sale or
otherwise hereunder and the Collateral Agent may apply the purchase price to the
payment of the Secured Obligations. Any purchaser of all or any part of the
Pledged Collateral shall, upon any such purchase, acquire good title to the
Pledged Collateral so purchased, free of the security interests created by this
Agreement.

      Section 5.4 Application of Proceeds. The Collateral Agent shall apply any
proceeds from time to time held by it and the net proceeds of any collection,
recovery, receipt, appropriation, realization or sale with respect to the
Pledged Collateral in accordance with and subject to the Collateral Trust
Agreement. For avoidance of doubt, it is understood that the Company shall
remain liable to the extent of any deficiency between the amount of proceeds of
the Pledged Collateral and the aggregated amount of the Secured Obligations.

                                   ARTICLE 6.
                            MISCELLANEOUS PROVISIONS

      Section 6.1 Notices. Unless otherwise specifically herein provided, any
notice or other communication required or permitted under the terms and
provisions hereof shall be in writing and any such notice shall become effective
if given in accordance with the provisions of Section 8.5 of the Collateral
Trust Agreement (and, in the case of notices to Pledgor, addressed to Pledgor's
chief executive office as set forth in Section 3.6).

      Section 6.2 Continuing Security Interest. This Agreement shall create a
continuing security interest in the Pledged Collateral until the release thereof
pursuant to Section 6.3.

      Section 6.3 Release. Upon the Secured Obligations Termination Date, or any
sale or other transfer of the Pledged Collateral permitted under this Agreement
and the other Secured Debt Documents, the Collateral Agent, upon the request,
and at the expense, of Pledgor, and acting pursuant to written instructions from
Pledgor, shall execute and deliver all such documentation as Pledgor may
reasonably request to release the security interest created pursuant to this
Agreement.

      Section 6.4 Reinstatement. This Agreement shall continue to be effective
or be reinstated, as the case may be, if at any time any amount received by the
Collateral Agent or any other Secured Party hereunder or pursuant hereto is
rescinded or must otherwise be restored or returned by the Collateral Agent or
such Secured Party upon a Bankruptcy Event of Pledgor, the Company or any of the
Guarantors or upon the appointment of any intervenor or conservator of, or
trustee or similar official for, Pledgor, the Company or any of the Guarantors
or any substantial part of Pledgor, the Company or any of the Guarantors'
assets, or upon the entry of an

                                       13
<PAGE>

order by any court avoiding the payment of such amount, or otherwise, all as
though such payments had not been made.

      Section 6.5 Independent Security. The security provided for in this
Agreement shall be in addition to and shall be independent of every other
security which the Secured Parties may at any time hold for any of the Secured
Obligations hereby secured, whether or not under the Security Documents. The
execution of any other Security Document shall not modify or supersede the
security interest or any rights or obligations contained in this Agreement and
shall not in any way affect, impair or invalidate the effectiveness and validity
of this Agreement or any term or condition hereof. Pledgor hereby waives its
right to plead or claim in any court that the execution of any other Security
Document is a cause for extinguishing, invalidating, impairing or modifying the
effectiveness and validity of this Agreement or any term or condition contained
herein. The Collateral Agent shall be at liberty to accept further security from
Pledgor or from any third party and/or release such security without notifying
Pledgor and without affecting in any way the obligations of Pledgor under the
this Agreement. The Collateral Agent shall determine if any security conferred
upon the Secured Parties under the Security Documents shall be enforced by the
Collateral Agent, as well as the sequence of securities to be so enforced.

      Section 6.6 Amendments. No waiver, amendment, modification or termination
of any provision of this Agreement, or consent to any departure by Pledgor or
the Company therefrom, shall in any event be effective without the prior written
consent of each of the parties hereto, and none of the Pledged Collateral shall
be released without the written consent of the Collateral Agent. Any such waiver
or consent shall be effective only in the specific instance and for the specific
purpose for which given.

      Section 6.7 Successors and Assigns. This Agreement shall be binding upon
Pledgor and the Company and their respective successors, transferees and assigns
and shall inure to the benefit of the Collateral Agent and the other Secured
Parties and their respective successors, transferees and assigns. Neither
Pledgor nor the Company shall assign or otherwise transfer any of its rights or
obligations under this Agreement without the written consent of the Collateral
Agent.

      Section 6.8 Third Party Beneficiaries. The agreements of the parties
hereto are intended to benefit the Secured Parties and their respective
successors and assigns.

      Section 6.9 Survival. All agreements, statements, representations and
warranties made by Pledgor and the Company herein or in any certificate or other
instrument delivered by Pledgor or on its behalf under this Agreement shall be
considered to have been relied upon by the Collateral Agent and the other
Secured Parties and shall survive the execution and delivery of this Agreement
until termination hereof or the indefeasible payment in full in cash or Cash
Equivalents of all of the Secured Obligations regardless of any investigation
made by the Collateral Agent or the other Secured Parties or made on their
behalf.

      Section 6.10 No Waiver; Remedies Cumulative. No failure or delay on the
part of the Collateral Agent in exercising any right, power or privilege
hereunder and no course of dealing between any of the parties hereto shall
operate as a waiver thereof; nor shall any single or partial exercise of any
right, power or privilege hereunder preclude any other or further exercise
thereof

                                       14
<PAGE>

or the exercise of any other right, power or privilege hereunder or thereunder.
The rights and remedies herein expressly provided are cumulative and not
exclusive of any rights or remedies which the Collateral Agent would otherwise
have.

      Section 6.11 Counterparts. This Agreement may be executed in any number of
counterparts and by the different parties hereto on separate counterparts, each
of which when so executed and delivered shall be an original, but all of which
shall together constitute one and the same instrument.

      Section 6.12 Headings Descriptive. The headings of the several sections
and subsections of this Agreement are inserted for convenience only and shall
not in any way affect the meaning or construction of any provision of this
Agreement.

      Section 6.13 Severability. In case any provision contained in or
obligation under this Agreement shall be invalid, illegal or unenforceable in
any jurisdiction, the validity, legality and enforceability of the remaining
provisions or obligations, or of such provision or obligation in any other
jurisdiction, shall not in any way be affected or impaired thereby.

      Section 6.14 Governing Law. This Agreement shall be governed by the laws
of the State of New York of the United States of America and shall for all
purposes be governed by and construed in accordance with the laws of such state
without regard to the conflict of law rules thereof other than Section 5-1401 of
the New York General Obligations Law.

      Section 6.15 Consent to Jurisdiction. ALL JUDICIAL PROCEEDINGS BROUGHT
AGAINST PLEDGOR OR THE COMPANY ARISING OUT OF OR RELATING HERETO OR ANY OTHER
TRANSACTION DOCUMENT, OR ANY OF THE OBLIGATIONS, MAY BE BROUGHT IN ANY STATE OR
FEDERAL COURT OF COMPETENT JURISDICTION IN THE STATE, COUNTY AND CITY OF NEW
YORK. BY EXECUTING AND DELIVERING THIS AGREEMENT, EACH PARTY, FOR ITSELF AND IN
CONNECTION WITH ITS PROPERTIES, IRREVOCABLY ACCEPTS GENERALLY AND
UNCONDITIONALLY THE NONEXCLUSIVE JURISDICTION AND VENUE OF SUCH COURTS; WAIVES
ANY DEFENSE OF FORUM NON CONVENIENS; AGREES THAT SERVICE OF ALL PROCESS IN ANY

JURISDICTION OVER IT, AS APPLICABLE, IN ANY SUCH PROCEEDING IN ANY SUCH COURT,
AND OTHERWISE CONSTITUTES EFFECTIVE AND BINDING SERVICE IN EVERY RESPECT; AND
AGREES THAT THE SERVICE PROCESS MAY BE MADE IN ANY OTHER MANNER PERMITTED BY LAW
OR TO BRING PROCEEDINGS AGAINST ANY PARTY HERETO IN THE COURTS OF ANY OTHER
JURISDICTION.

      Section 6.16 Waiver of Jury Trial. EACH OF THE PARTIES HERETO HEREBY
KNOWINGLY, VOLUNTARILY AND INTENTIONALLY WAIVES ANY RIGHTS IT MAY HAVE TO A
TRIAL BY JURY IN RESPECT OF ANY LITIGATION BASED HEREON, OR ARISING OUT OF,
UNDER OR IN CONNECTION WITH, THIS AGREEMENT, OR ANY COURSE OF CONDUCT, COURSE OF
DEALING, STATEMENTS (WHETHER VERBAL

                                       15
<PAGE>

OR WRITTEN) OR ACTIONS OF THE OTHER PARTIES HERETO. THIS PROVISION IS A MATERIAL
INDUCEMENT FOR THE COLLATERAL AGENT TO ENTER INTO THIS AGREEMENT.

      Section 6.17 Entire Agreement. This Agreement, together with any other
agreement executed in connection herewith (including the Collateral Trust
Agreement), is intended by the parties as a final expression of their agreement
as to the matters covered hereby and is intended as a complete and exclusive
statement of the terms and conditions thereof.

      Section 6.18 Independent Obligations. Pledgor's obligations under this
Agreement are independent of those of the Company. The Collateral Agent may
bring a separate action against Pledgor without first proceeding against the
Company or any other Person or any other security held by the Collateral Agent
and without pursuing any other remedy.

      Section 6.19 Waiver of Defenses. Pledgor hereby waives: (a) any defense of
a statute of limitations; (b) any defense based on the legal disability of the
Company or any discharge or limitation of the liability of the Company to the
Collateral Agent or the Secured Parties, whether consensual or arising by
operation of law; (c) presentment, demand, protest and notice of any kind (other
than as expressly provided by the Secured Debt Documents); and (d) any defense
based upon or arising out of any defense which the Company may have to the
payment or performance of any part of the Secured Obligations.

      Section 6.20 Subrogation. Etc. Notwithstanding any payment or payments
made by Pledgor or the exercise by the Collateral Agent of any of the remedies
provided under this Agreement or any other Secured Debt Document, until the
Secured Obligations Termination Date, Pledgor shall have no claim (as defined in
11 U.S.C. Section 101(5)) of subrogation to any of the rights of the Collateral
Agent against the Company, the Pledged Collateral or any guaranty held by the
Collateral Agent for the satisfaction of any of the Secured Obligations, nor
shall Pledgor have any claims (as defined in 11 U.S.C. Section 101(5)) for
reimbursement, indemnity, exoneration or contribution from the Company in
respect of payments made by Pledgor hereunder. Notwithstanding the foregoing, if
any amount shall be paid to Pledgor on account of such subrogation,
reimbursement, indemnity, exoneration or contribution rights at any time, such
amount shall be held by Pledgor in trust for the Collateral Agent segregated
from other funds of Pledgor, and shall be turned over to the Collateral Agent in
the exact form received by Pledgor (duly endorsed by Pledgor to the Collateral
Agent if required) to be applied against the Secured Obligations in such amounts
and in such order as the Collateral Agent may elect.

      Section 6.21 Collateral Trust Agreement. All the provisions contained in
this Agreement are expressly subject to all of the provisions contained in the
Collateral Trust Agreement in all respects. The rights, powers, benefits,
privileges, immunities and indemnities given to the Collateral Agent and set

and shall survive the termination of this Agreement and the resignation or
removal of the Collateral Agent.
