                    Guarantor is obligated to pay under Section 2.1(b)
                    hereof under the circumstances specified therein).

               d)   Notwithstanding anything herein or in the Collateral Trust
                    Indenture to the contrary, in the event that an
                    Indenture Event of Default that constitutes a Lease
                    Event of Default has occurred and is continuing and the
                    Indenture Trustee (as assignee of the Owner Lessor)
                    forecloses upon and sells, assigns or otherwise
                    transfers, its interest in this Guaranty pursuant to the
                    provisions of the Collateral Trust Indenture, the
                    Guarantor shall remain obligated hereunder

                    to pay to the Owner Lessor the amounts referred to in
                    Section 2.1(a)(3).

     B.   In the case of any failure by the South Point Lessee to perform and
          observe any term, provision or condition referred to in Section
          2.1(a) when due pursuant to the Operative Documents or the South
          Point Ground Lease, the Guarantor agrees to cause such performance
          or observance to be done, and in the case of any failure by the
          South Point Lessee to make such payment as and when the same shall
          become due and payable (by acceleration or otherwise), the Guarantor
          hereby agrees to make such payment (and, in addition, such further
          amounts, if any, as shall be sufficient to cover the costs and
          expenses of collection hereunder) as and when such payment is due
          and payable.

          All obligations and indebtedness set forth in Section 2.1 above, this
Section 2.2, and in Section 8.15 below are referred to in this Guaranty as the
"Obligations."

     C.   The obligations of the Guarantor contained herein are direct,
          independent, and primary obligations of the Guarantor and are
          absolute, present, unconditional and continuing obligations and are
          not conditioned in any way upon the institution of suit or the
          taking of any other action or any attempt to enforce performance of
          or compliance with the obligations, covenants or undertakings
          (including any payment obligations) of the South Point Lessee and
          shall constitute a guaranty of, and agreement with respect to,
          payment and performance and not a guaranty of collection, binding
          upon the Guarantor and its successors and assigns and shall remain
          in full force and effect and irrevocable without regard to the
          genuineness, validity, legality or enforceability of the

          Document and the South Point Ground Lease) to which the South Point

          any other circumstance whatsoever that might otherwise constitute a

          counterclaim and is in no way conditioned or contingent upon any
          attempt to collect from the South Point Lessee or any other entity
          or to perfect or enforce any security or upon any other condition or

III. GUARANTOR'S REPRESENTATIONS, WARRANTIES AND
     COVENANTS

     A.   The Guarantor represents and warrants, as of the date hereof:

          1.   The Guarantor is duly organized, validly existing and in good
               standing under the laws of the State of Delaware and has full
               power, authority and the legal right to execute, deliver and
               perform the terms of this Guaranty and each Operative Document
               to which it is a party (together, the "Calpine Documents").

          2.   The execution, delivery and performance by the Guarantor of the
               Calpine Documents have been duly authorized by all necessary
               corporate action. The Calpine Documents constitute legal,
               valid and binding obligations of the Guarantor enforceable
               against the Guarantor in accordance with their respective
               terms, except as such enforcement may be affected by
               applicable bankruptcy, insolvency, moratorium and other
               similar laws affecting creditors' rights generally and by
               general principles of equity.

          3.   The execution, delivery and performance of the Calpine Documents
               will not (a) contravene any provision of law, rule or
               regulation to which the Guarantor is subject or any judgment,
               decree or order applicable to the Guarantor, (b) conflict or
               be inconsistent with or result in any breach of any terms,
               covenants, conditions or provisions of, or constitute a
               default under, or result in the creation or imposition of (or
               the obligation to create or impose) any Lien or other
               encumbrance upon any of the property or assets of the
               Guarantor pursuant to the terms of any agreement or other
               instrument to which the Guarantor is a party or by which it or
               its property is bound or to which it or its property may be
               subject, in each case the violation of which would have a
               material adverse effect on the business, operations,
               prospects, properties or assets, or in the condition,
               financial or otherwise, of the Guarantor, or (c) violate or
               contravene any provision of the articles of incorporation or
               by-laws of the Guarantor.

          4.   No pending or, to the knowledge of the Guarantor, threatened
               action, suit, investigation or proceedings against the
               Guarantor before any Governmental Entity exists which, if
               determined

                                       8

               adversely to the Guarantor, would materially adversely affect
               the business, operations, prospects, properties or assets, or
               in its condition, financial or otherwise, or the Guarantor's
               ability to perform its obligations under the Calpine
               Documents.

          5.   No consent from, authorization or approval or other action by,
               and no notice to or filing with, any Person is required for
               the execution, delivery and performance by the Guarantor of
               the Calpine Documents except those which have been given and
               remain in full force and effect.

          6.   The South Point Lessee is an indirect, wholly-owned subsidiary
               of the Guarantor.

          7.   The Guarantor is not an "investment company" or a company
               controlled by an "investment company" within the meaning of
               the Investment Company Act of 1940.

          8.   The Guarantor is not in default with respect to any judgment,
               order, writ, injunction, decree, award, rule or regulation
               of any court, arbitrator or governmental department,
               commission, board, bureau, agency or instrumentality, domestic
               or foreign, which, either, separately or in the aggregate,
               would result in any material adverse change in any of its
               businesses, operations, prospects or assets, or in its
               condition, financial or otherwise, or its ability to perform
               its obligations under the Calpine Documents.

          9.   The Guarantor is not a party to any agreement or instrument, or
               subject to any corporate restriction or any judgment, order,
               writ, injunction, decree, award, rule or regulation, which
               materially adversely affects, or in the future may materially
               adversely affect, its business, operations, prospects,
               properties or assets, or conditions, financial or otherwise,
               or its ability to perform its obligations under the Calpine
               Documents.

          10.  The audited financial statements of the Guarantor and its
               Consolidated Subsidiaries, as of December 31, 2000, reported
               on by Arthur Andersen LLP, copies of which have been delivered
               to the Indenture Trustee, the Pass Through Trustee, the
               Certificateholders and the Owner Participant, are true,
               complete and correct and fairly present the financial
               condition of the Guarantor and its Consolidated Subsidiaries
               as of the date thereof. The financial statements have been
               prepared in accordance with GAAP. The Guarantor and its
               Consolidated Subsidiaries do not have any material
               liabilities, direct or contingent, except (a) as are disclosed
               in such financial statements or (b) as arise under the
               Operative Documents or the South Point Ground Lease. There has

                                       9

               been no material adverse change in the financial condition of
               the Guarantor and its Consolidated Subsidiaries since the date
               of the audited financial statements referred to above.

          11.  All factual information relating to the Guarantor (taken as a
               whole) heretofore or contemporaneously furnished by or on
               behalf of the Guarantor in writing to the Owner Lessor, the
               Owner Participant, the Indenture Trustee, the Pass Through
               Trustee or the Certificateholders (including, without
               limitation, all such information contained herein, in the
               Participation Agreement and in any preliminary or final
               offering circular distributed in accordance with the terms of
               the Operative Documents) for purposes of or in connection with
               the Calpine Documents or any transaction contemplated therein
               is true and accurate in all material respects on the date as
               of which such information is dated or certified and not
               incomplete by omitting to state any fact necessary to make
               such information relating to the Guarantor (taken as a whole)
               not misleading in any material respect at such time in light
               of the circumstances under which such information was
               provided; provided, that no representation or warranty is made
               with regard to (i) any projections or other forward-looking
               statements provided by or on behalf of the Guarantor, or (ii)
               the descriptions of the Operative Documents or the South Point
               Ground Lease or the tax consequences to beneficial owners of
               Certificates; provided, however, each of the Beneficiaries
               acknowledges and agrees that (i) Calpine has heretofore
               provided to the Appraiser, solely in order to assist the
               Appraiser in connection with the preparation of the appraisal
               to be delivered by the Appraiser to certain of the Transaction
               Parties at the Closing, certain (1) general market
               information, (2) information about the Arizona energy market
               and (3) information passed along from other Persons and (ii)
               that the South Point Lessee does not make any representation
               or warranty whatsoever with respect to the information
               described in clause (i) above except to the extent expressly
               set forth in Section 4(b) of the Tax Indemnity Agreement.

          12.  The Guarantor is in compliance with all applicable statutes,
               regulations and orders of, and all applicable restrictions
               imposed by, all governmental bodies, domestic or foreign, in
               respect of the conduct of its business and the ownership of
               its property (including applicable statutes, regulations,
               orders and restrictions relating to environmental standards
               and controls), except such noncompliance as would not, in the
               aggregate, have a material adverse effect on the business,
               operations, property, assets or condition (financial or
               otherwise) of the Guarantor, or the Guarantor's ability to
               perform its obligations under the Calpine Documents.

                                       10

          13.  The Guarantor has filed all tax returns and reports required by
               law to have been filed by it and has paid all taxes and
               governmental charges thereby shown to be owing (other than any
               such taxes or charges which are being diligently contested in
               good faith by appropriate proceedings and for which adequate
               reserves in accordance with GAAP shall have been set aside on
               its books), except such non-filing or non-payment, as the case
               may be, as would not, in the aggregate, have a material
               adverse effect on the business, operations, property, assets
               or condition (financial or otherwise) of the Guarantor. 14. No
               default has occurred under this Guaranty, which default would
               reasonably be expected to result in a material adverse effect
               on the business, operations, assets or condition (financial or
               otherwise) of the Guarantor.

          14.  No default has occurred under this Guaranty, which default would
               reasonably be expected to result in a material adverse effect on
               the business, operations, assets or condition (financial or
               otherwise) of the Guarantor.

          15.  In accordance with Section 8.12 hereof and Section 14.14 of the
               Participation Agreement, the Guarantor has validly submitted
               to the jurisdiction of the Supreme Court of the State of New
               York, New York County and the United States District Court for
               the Southern District of New York.

      B.  The Guarantor covenants and agrees that on and after the date hereof
          and until this Guaranty is terminated pursuant to the terms hereof
          the Guarantor shall:

               a)   file with the Owner Participant and the Indenture Trustee,
                    within 15 days after the filing with the SEC, copies of
                    the annual reports and of the information, documents and
                    other reports (or copies of such portions of any of the
                    foregoing as the SEC may by rules and regulations
                    prescribe) which the Guarantor is required to file with
                    the SEC pursuant to Section 13 or 15(d) of the Exchange
                    Act. In the event the Guarantor is at any time no longer
                    subject to the reporting requirements of Section 13 or
                    15(d) of the Exchange Act, it shall file with the Owner
                    Participant, and for so long as the Certificates remain
                    outstanding, the Indenture Trustee and the Pass Through
                    Trustee, within 15 days after the Guarantor would have
                    been required to file such documents with the SEC,
                    copies of the annual reports and of the information,
                    documents and other reports which the Guarantor would
                    have been required to file with the SEC if the Guarantor
                    had continued to be subject to such Sections 13 or
                    15(d). Delivery of such reports, information and
                    documents to the Owner Participant, the Indenture
                    Trustee and the Pass Through Trustee is for
                    informational purposes only and their receipt of the
                    same shall not constitute

                                       11

                    constructive notice of any information contained
                    therein or determinable from information contained
                    therein, including the Guarantor's compliance with any
                    of its covenants hereunder (as to which the Owner
                    Participant, the Indenture Trustee and the Pass Through
                    Trustee are entitled to rely exclusively on Officers'
                    Certificates);

               b)   furnish to the Beneficiaries, promptly upon the Guarantor
                    obtaining Actual Knowledge of any action, suit or
                    proceeding pending or threatened against the Guarantor
                    before any court or before any governmental department,
                    commission or agency or any arbitrator, which in the
                    Guarantor's good faith opinion would reasonably be
                    likely to result in a material adverse effect on the
                    business, operations, property, assets or condition
                    (financial or otherwise) of the Guarantor, a certificate
                    of a senior officer specifying the nature of such
                    action, suit or proceeding and the proposed response of
                    the Guarantor thereto;

               c)   furnish to the Beneficiaries, as soon as possible and in
                    any event within three days after the Guarantor obtains
                    Actual Knowledge of default by the Guarantor of any of
                    its material obligations under this Guaranty, a
                    statement of an authorized officer of the Guarantor
                    setting forth details of such default and the action
                    which the Guarantor has taken and proposes to take with
                    respect thereto. Notwithstanding the foregoing provision
                    in this clause (c), the Guarantor shall, within 120 days
                    after the close of each fiscal year of the Guarantor in
                    which Certificates are outstanding hereunder, file with
                    the Owner Participant, and if the Certificates are
                    outstanding during any part of such fiscal year, the
                    Indenture Trustee and the Pass Through Trustee, an
                    Officer's Certificate, provided that one Officer
                    executing the same shall be the principal executive
                    officer, the principal financial officer or the
                    principal accounting officer of the Guarantor, covering
                    the period from the date hereof to the end of the fiscal
                    year in which this Guaranty was executed and delivered
                    by the Guarantor, in the case of the first such
                    certificate, and covering the preceding fiscal year in
                    the case of each subsequent certificate, and stating
                    whether or not, to the Actual Knowledge of each such
                    executing Officer, the Guarantor has complied with and
                    performed and fulfilled all covenants on its part
                    contained in this Guaranty and is not in Default in the
                    performance or observance of any of the terms or
                    provisions contained in this Guaranty, and, if any such
                    signer has obtained Actual Knowledge of any Default by
                    the Guarantor in the

                                       12

                    performance, observance or fulfillment of any such
                    covenant, terms or provision specifying each such
                    Default and the nature thereof; and

               d)   promptly furnish to the Owner Participant, the Owner
                    Lessor, the Indenture Trustee or the Pass Through
                    Trustee such other information as the Owner Lessor,
                    Owner Participant, the Indenture Trustee and the Pass
                    Through Trustee may from time to time reasonably request
                    with respect to the Guarantor.

     So long as the Indenture Trustee is also serving as the Pass Through
Trustee, delivery to the Indenture Trustee shall satisfy the Guarantor's
obligation to furnish information to the Pass Through Trustee under this
Section 3.2.

     C.   The Guarantor covenants and agrees that it will not transfer or
          assign or cause to be transferred or assigned the Ownership
          Interest in the South Point Lessee to any other Person, without the
          prior written consent of the Owner Lessor, the Owner Participant
          and, so long as the Lien of the Collateral Trust Indenture has not
          been terminated or discharged, the Indenture Trustee and the Pass
          Through Trustee (it being agreed and understood that a consolidation
          with or merger of the Guarantor into, or a sale by the Guarantor of
          all or substantially all of its assets to, another Person in
          accordance with Section 3.6 hereof shall not be deemed to be a
          transfer or assignment of the Ownership Interest in the South Point
          Lessee for the purposes of this Section), except as permitted in
          this Section 3.3 or in Section 8.4 hereof. Notwithstanding the
          foregoing, and subject to Section 8.4 below, so long as this
          Guaranty remains in full force and effect, the Guarantor may
          transfer a portion of the Ownership Interest in the South Point
          Lessee (provided that following such transfer the Guarantor shall
          continue to own at least a majority of the Ownership Interest in the
          South Point Lessee) without the consent of the Owner Lessor, the
          Owner Participant, the Indenture Trustee, the Pass Through Trustee
          or any other Transaction Party if the following conditions have been
          satisfied:

          1.   the Owner Lessor, the Owner Participant and, so long as the Lien
               of the Collateral Trust Indenture shall not have been
               terminated or discharged, the Indenture Trustee and the Pass
               Through Trustee shall have received an Opinion of Counsel to
               the effect that all regulatory approvals required in
               connection with such transfer have been obtained;

          2.   all the obligations of the South Point Lessee under the
               Operative Documents and the South Point Ground Lease shall

          5.   the South Point Lessee shall have paid, at no after-tax cost to
               such parties, all reasonable and documented out-of-pocket

     D.   Subject to Section 4, the Guarantor shall not, and shall not permit
          any Restricted Subsidiary to, enter into any Sale/Leaseback
          Transaction unless (i) the Guarantor or such Restricted Subsidiary
          would be entitled to create a Lien on such property securing
          Indebtedness in an amount equal to the Attributable Debt with
          respect to such transaction without equally and ratably securing the
          Obligations pursuant to Section 3.5 or (ii) the net proceeds of such
          sale are at least equal to the fair value (as determined by the
          Board of Directors) of such property or asset and the Guarantor or
          such Restricted Subsidiary shall apply or cause to be applied an
          amount in cash equal to the net proceeds of such sale to the
          retirement, within 180 days of the effective date of any such
          arrangement, of Indebtedness of the Guarantor or any Restricted
          Subsidiary; provided, however, that in addition to the transactions
          permitted pursuant to the foregoing clauses (i) and (ii), the
          Guarantor or any Restricted Subsidiary may enter into a
          Sale/Leaseback Transaction as long as the sum of (x) the
          Attributable Debt with respect to such Sale/Leaseback Transaction
          and all other Sale/Leaseback Transactions entered into pursuant to
          this proviso plus (y) the amount of outstanding Indebtedness secured
          by Liens Incurred pursuant to the final proviso to Section 3.5 does
          not exceed 15% of Consolidated Net Tangible Assets as determined
          based on the consolidated balance sheet of the Guarantor as of the
          end of the most recent fiscal quarter for which financial statements
          are available; and provided, further, that a Restricted Subsidiary
          may enter into a Sale/Leaseback Transaction with respect to property
          or assets owned by such Restricted Subsidiary, the proceeds of which
          are used to explore,

                                       14

          drill, develop, construct, purchase, repair, improve or add to
          property or assets of any Restricted Subsidiary, or to repay (within
          365 days of the commencement of full commercial operation of any
          such property) Indebtedness Incurred to explore, drill, develop,
          construct, purchase, repair, improve or add to property or assets of
          any Restricted Subsidiary.

     E.   Subject to Section 4, the Guarantor shall not, and shall not permit
          any Restricted Subsidiary to, directly or indirectly, incur any
          Lien on any of its properties or assets (including Capital Stock),
          whether owned at the date hereof or thereafter acquired, in each
          case to secure Indebtedness of the Guarantor or any Restricted
          Subsidiary, other than (a)(1) Liens incurred by the Guarantor or any
          Restricted Subsidiary securing Indebtedness Incurred by the
          Guarantor or such Restricted Subsidiary, as the case may be, to
          finance the exploration, drilling, development, construction or
          purchase of or by, or repairs, improvements or additions to,
          property or assets of the Guarantor or such Restricted Subsidiary,
          as the case may be, which Liens may include Liens on the Capital
          Stock of such Restricted Subsidiary or (2) Liens incurred by any
          Restricted Subsidiary that does not own, directly or indirectly, at
          the time of such original incurrence of such Lien under this clause
          (2) any operating properties or assets, securing Indebtedness
          Incurred to finance the exploration, drilling, development,
          construction or purchase of or by, or repairs, improvements or
          additions to, property or assets of any Restricted Subsidiary that
          does not, directly or indirectly, own any operating properties or
          assets at the time of such original incurrence of such Lien, which
          Liens may include Liens on the Capital Stock of one or more
          Restricted Subsidiaries that do not, directly or indirectly, own any
          operating properties or assets at the time of such original
          incurrence of such Lien, provided, however, that the Indebtedness
          secured by any such Lien may not be issued more than 365 days after
          the later of the exploration, drilling, development, completion of
          construction, purchase, repair, improvement, addition or
          commencement of full commercial operation of the property or assets
          being so financed; (b) Liens existing on the date hereof (other than
          Liens relating to Indebtedness or other obligations being repaid or
          Liens that are otherwise extinguished with the proceeds of the
          offering of the Certificates); (c) Liens on property, assets or
          shares of stock of a Person at the time such Person becomes a
          Subsidiary; provided, however, that any such Lien may not extend to
          any other property or assets owned by the Guarantor or any
          Restricted Subsidiary; (d) Liens on property or assets at the time
          the Guarantor or a Subsidiary acquires the property or asset,
          including any acquisition by means of a merger or consolidation with
          or into the Guarantor or a Subsidiary; provided, however, that such
          Liens are not incurred in connection with, or in contemplation of,
          such merger or consolidation; and provided, further, that the Lien
          may not extend to any other property or asset owned by the Guarantor
          or any Restricted Subsidiary; (e) Liens securing Indebtedness or
          other obligations of a Subsidiary owing to the Guarantor or a
          Restricted Subsidiary or of the

                                       15

          Guarantor owing to a Subsidiary; (f) Liens incurred on assets that
          are the subject of a Capitalized Lease Obligation to which the
          Guarantor or a Subsidiary is a party, which shall include, Liens on
          the stock or other ownership interest in one or more Restricted
          Subsidiaries leasing such assets; (g) Liens to secure any
          refinancing, refunding, extension, renewal or replacement (or
          successive refinancings, refundings, extensions, renewals or
          replacements) as a whole, or in part, of any Indebtedness secured by
          any Lien referred to in the foregoing clauses (a), (b), (c), (d) and
          (f), provided, however, that (x) such new Lien shall be limited to
          all or part of the same property or assets that secured the original
          Lien (plus repairs, improvements or additions to such property or
          assets and Liens on the stock or other ownership interest in one or
          more Restricted Subsidiaries beneficially owning such property or
          assets) and (y) the amount of the Indebtedness secured by such Lien
          at such time (or, if the amount that may be realized in respect of
          such Lien is limited, by contract or otherwise, such limited lesser
          amount) is not increased (other than by an amount necessary to pay
          fees and expenses, including premiums, related to the refinancing,
          refunding, extension, renewal or replacement of such Indebtedness);
          (h) Liens by which the Obligations are secured equally and ratably
          with other Indebtedness pursuant to this Section 3.5; in any such
          case without effectively providing that the Obligations shall be
          secured equally and ratably with (or prior to) the obligations so
          secured for so long as such obligations are so secured; provided,
          however, that the Guarantor or a Restricted Subsidiary may Incur
          other Liens to secure outstanding Indebtedness as long as the sum of
          (x) the lesser of (A) the amount of outstanding Indebtedness secured
          by Liens Incurred pursuant to this proviso (or, if the amount that
          may be realized in respect of such Lien is limited, by contract or
          otherwise, such limited lesser amount) and (B) the fair value (as
          determined by the Board of Directors) of the property securing such
          item of Indebtedness, plus (y) the Attributable Debt with respect to
          all Sale/Leaseback Transactions entered into pursuant to the first
          proviso to Section 3.4 does not exceed 15% of Consolidated Net
          Tangible Assets as determined based on the Consolidated balance

          quarter for which financial statements are available; and (i) Liens
          otherwise permitted under the 2000 Calpine Indenture.

     F.   (a) The Guarantor covenants and agrees that it shall not consolidate
          or merge with or into any other Person, or sell, assign, convey,
          lease, transfer or otherwise dispose of, all or substantially all of
          its properties or assets to any Person or Persons in one or a series
          of transactions, unless immediately after giving effect to such
          transaction,

          1.   no Significant Lease Default or Lease Event of Default shall
               have occurred and be continuing;

                                       16

          2.   either (A) the Guarantor shall be the continuing Person, or (B)
               the Person (if other than the Guarantor) formed by such
               consolidation or into which the Guarantor is merged or to
               which the properties and assets of the Guarantor are sold,
               assigned, conveyed, transferred, disposed of or leased as
               aforesaid shall be an entity organized and existing under the
               laws of the United States or any State thereof or the District
               of Columbia and shall execute and deliver to the Owner
               Participant, the Owner Lessor and, so long as the Lien of the
               Collateral Trust Indenture shall not have been terminated or
               discharged, the Indenture Trustee and the Pass Through
               Trustee, a Guarantor Assignment and Assumption Agreement; and

          3.   each of the Owner Participant, the Owner Lessor and, so long as
               the Lien of the Collateral Trust Indenture shall not have
               been terminated or discharged, the Indenture Trustee and the
               Pass Through Trustee shall have received an Officer's
               Certificate of the Guarantor, the surviving entity or the
               transferee, as the case may be, in form and substance
               reasonably satisfactory to each of such parties, stating that
               the proposed merger, consolidation, assignment, conveyance,
               transfer, disposition, lease or sale, and the Guarantor
               Assignment and Assumption Agreement complies with the terms of
               this Section 3(a) and, as to legal matters, an Opinion of
               Counsel; and

          4.   In addition to the conditions set forth in clauses (i) through
               (iii) above, the Guarantor, subject to Section 4, will not
               consummate any such consolidation, merger or sale of all or
               substantially all of its properties or assets unless the
               long-term unsecured debt of the resulting, surviving or
               succeeding entity shall have a credit rating assigned by the
               Rating Agencies that is not less than the lower of (x) the
               credit rating of the long-term unsecured debt of the Guarantor
               assigned by the Rating Agencies immediately prior to such
               transaction and (y) a credit rating of the long-term unsecured
               debt of the resulting, surviving or succeeding entity assigned
               by the Rating Agencies that is Investment Grade; provided
               however, the foregoing credit rating condition set forth in
               this paragraph may be waived by the Owner Participant in its
               sole discretion, and provided further, that if such credit
               rating condition is not otherwise satisfied, or waived by the
               Owner Participant, the Guarantor, the surviving entity or the
               transferee, as the case may be, may provide in the
               alternative, either (A) a letter of credit from a L/C Bank
               with at least either (1) an A rating from S&P or (2) an A2
               rating from Moody's, in either case, covering the Equity
               Portion of Termination Value from time to time throughout the
               Lease Term, or (B) alternative or additional credit support
               arrangements which result in the satisfaction of the rating

                                       17

               condition in either clause (x) or clause (y) above, provided
               that such arrangements contemplated in this sub-clause (B) are
               satisfactory to the Owner Participant and result in the
               satisfaction of such rating condition.

          (b) Upon the consummation of such transaction described in Section
3.6(a), the resulting, surviving or succeeding entity, if other than the
Guarantor, shall succeed to, and be substituted for, and may exercise every
right and power and shall perform every obligation of, the Guarantor under this
Guaranty and each other Calpine Document, and from and after the effective date
and time of the consummation of such transfer, the Guarantor shall be released
from all obligations accruing hereunder other than those accruing prior to such
effective date and time.

     G.   The Guarantor shall, together with each payment it makes hereunder,
          provide a written notice to each Beneficiary or Beneficiaries which
          are the intended recipients of such payment of the amount payable to
          each such Beneficiary and the Operative Document(s) with respect to
          which such payment is being made.

IV.   BENEFICIARIES; TERMINATION OF CERTAIN COVENANTS

          The Owner Participant, the Owner Lessor, the Trust Company (but only
to the extent indemnified under the Participation Agreement) and, so long as
the Lien of the Collateral Trust Indenture has not been terminated or
discharged, the Indenture Trustee and the Lease Indenture Company, and (but
only to the extent expressly referred to herein, and with respect to Section
3.2(a) hereof and with respect to the obligations of the South Point Lessee
under the Participation Agreement) the Pass Through Trustee (for the benefit of
the Certificateholders) and the Pass Through Company, in each case, together
with their respective permitted successors and assigns (and with respect to
clause (ii) below, the other related Persons referred to therein), are each
beneficiaries of this Guaranty (each a "Beneficiary" or, together, the
"Beneficiaries"); provided that, notwithstanding the foregoing or any other
provision of this Guaranty, (i) the Owner Participant shall be the sole and
exclusive beneficiary of, and shall have the sole right to enforce, (A) clause
(iv) of Section 3.6(a) hereof, (B) clause (4) of Section 2.1(a) hereof to the
extent relating to the South Point Lessee's indemnity obligation under the Tax
Indemnity Agreement, (ii) to the extent that the South Point Lessee is
obligated to indemnify a particular Beneficiary (or any Affiliate, agent
director, officer, or employee thereof) in accordance with Section 9 of the
Participation Agreement, then such Beneficiary (or such Affiliate, agent,
director, officer or employee) shall be the sole and exclusive beneficiary of,
and shall have the sole right to enforce, the Guarantor's guaranty of, and
agreement with respect to, such indemnification obligation hereunder, (iii) the

Section 3.4 and Section 3.5 hereof; provided however, with respect to this
clause (iv), once the Certificates shall have been paid in full, the

                                       18

covenants set forth in Section 3.4 and Section 3.5 hereof shall, subject to the
immediately following sentence, immediately and without any further action
terminate and be of no further force or effect. Any amendment, waiver or
modification of or supplement to Section 3.4 or Section 3.5 which is consented

of the Operative Documents to the contrary, if the Owner Lessor shall have
issued additional Lease Debt at the request of the South Point Lessee in
accordance with Section 11 of the Participation Agreement prior to,
simultaneously with, or after payment in full of the Certificates and such new
Lease Debt is outstanding on or after the date the Certificates are paid in
full, the covenants set forth in Section 3.4 and Section 3.5 shall, to the

thereafter become effective if not then in effect, but shall be for the sole
and exclusive benefit of, and enforceable solely by, the holder of such new
Lease Debt. Upon repayment of such new Lease Debt, or compliance with the terms
thereof, the covenants set forth in Section 3.4 and Section 3.5 shall
immediately and without further action terminate and be of no further force and
effect. Notwithstanding any of the preceding provisions, a breach of Sections
3.4 or 3.5 under this Guaranty at such time as such breach shall have become an
"Event of Default" under Section 7.1 shall constitute a Lease Event of Default
under the circumstances provided in, and to the extent set forth in, the
Facility Lease.

                    respect thereof or hereof, and may subordinate the
                    payment of all or any part thereof to the payment of any
                    liability (whether due or not) of the South Point Lessee

                    reduction (by operation of law or negotiation) of, any
                    of the Obligations (or amounts underlying such
                    Obligations) due to it (whether occurring before or
                    after the occurrence of a Lease Event of Default) shall
                    not alter the amount of the original Obligations due to
                    it guaranteed hereby and the Guarantor acknowledges and
                    agrees that its obligations hereunder shall be for the
                    full amount of the Obligations due to it without giving
                    effect to any such settlement, compromise or other
                    reduction;

               e)   apply any sums by whomsoever paid or howsoever realized to
                    any liability or liabilities of the South Point Lessee
                    to such Beneficiary regardless of what liabilities or
                    liabilities of the South Point Lessee remain unpaid;

               f)   consent to or waive any breach of, or any act, omission or
                    default under, the Participation Agreement or the
                    Facility Lease, or otherwise amend, modify or supplement
                    the Participation Agreement or the Facility Lease or any
                    of such other instruments or agreements; and/or

               g)   act or fail to act in any manner referred to in this
                    Guaranty which may deprive the Guarantor of its right
                    to subrogation against the South Point Lessee to recover
                    full indemnity for any payments made pursuant to this
                    Guaranty.

Anything herein to the contrary notwithstanding, any exercise of rights or
remedies by any Beneficiary hereunder or under any other Operative Document or
the South Point Ground Lease, or the failure of any Beneficiary to exercise any
rights or remedies hereunder in accordance with the provisions hereof or under
any other Operative Document or the South Point Ground Lease, shall not in any
way adversely affect the ability of any other Beneficiary to exercise its
rights or remedies hereunder.

VI.  SURVIVAL OF GUARANTY AND PAYMENT AGREEMENT (SOUTH POINT (SP-2))

          Notwithstanding anything to the contrary herein, this Guaranty shall
continue to be effective or be reinstated, as the case may be, if at any time
any of the amounts paid to any of the Beneficiaries, in whole or in part, is
required to be repaid upon the insolvency, bankruptcy, dissolution,
liquidation, or reorganization of the

                                       20

Guarantor or the South Point Lessee or any other Person, or as a result of the
appointment of a custodian, interviewer, receiver, trustee, or other officer
with similar powers with respect to the Guarantor or the South Point Lessee or
any other Person or any substantial part of the property of the Guarantor or
the South Point Lessee or such other Person, all as if such payments had not
been made.

VII. DEFAULTS; REMEDIES; SUBROGATION

     A.   Defaults. The following events shall constitute an "Event of Default"
          hereunder (whether any such event shall be voluntary or involuntary
          or come about or be effected by operation of law or pursuant to or
          in compliance with any judgment, decree or order of any court or any
          order, rule or regulation of any Governmental Entity):

               a)   the Guarantor or the South Point Lessee under the Facility
                    Lease shall fail to make any payment with respect to
                    Periodic Rent or the Termination Value (including the
                    Equity Portion of Termination Value and Debt Portion of
                    Termination Value) when due and payable under such
                    Facility Lease or this Guaranty within five (5) days
                    after the same shall become due thereunder; or

               b)   the Guarantor or the South Point Lessee shall fail to make
                    any other amount payable under any Operative Document
                    after the same shall become due thereunder and such
                    failure shall have continued from a period of ten (10)
                    Business Days after receipt by the South Point Lessee
                    and the Guarantor of written notice of such failure by
                    the South Point Lessee and/or the Guarantor, as
                    applicable;

               c)   The Guarantor shall fail to comply with its covenants set
                    forth in Section 3.3 (transfer of South Point Lessee
                    ownership), 3.6 (Guarantor merger) or 8.4 (assignment of
                    Guaranty) of this Guaranty.

               d)   the Guarantor shall fail to perform or observe any
                    covenant, obligation or agreement to be performed or
                    observed by it under any Calpine Document (other than
                    any covenant, obligation or agreement referred to in
                    clauses (a) or (b) of this Section 7.1) in any material
                    respect, which shall continue unremedied for (1) with
                    respect to the Guarantor's guaranty of, and agreement
                    with respect to, any nonmonetary obligation, covenant or
                    agreement of the South Point Lessee under any of the
                    Operative Documents or the South Point Ground Lease, 30
                    days after receipt by the Guarantor of written notice
                    thereof from the Owner Participant, the Owner Lessor,
                    the Indenture Trustee or the

                                       21

                    Pass Through Trustee; provided, however, if such
                    condition cannot be remedied within such 30-day period,
                    then the period within which to remedy such condition
                    shall be extended up to an additional 180 days, so long
                    as the Guarantor diligently pursues such remedy and such
                    condition is reasonably capable of being remedied within
                    such additional 180-day period, and (2) with respect to
                    any other obligation, covenant or agreement hereunder,
                    30 days after receipt by the Guarantor of written notice
                    thereof;

               e)   there shall have occurred either (i) a default by the
                    Guarantor or any Restricted Subsidiary under any
                    instrument or instruments under which there is or may be
                    secured or evidenced any Indebtedness of the Guarantor
                    or any Restricted Subsidiary of the Guarantor (other
                    than the Obligations) having an outstanding principal
                    amount of $50,000,000 (or its foreign currency
                    equivalent) or more individually or in the aggregate
                    that has caused the holders thereof to declare such
                    Indebtedness to be due and payable prior to its Stated
                    Maturity, unless such declaration has been rescinded
                    within 30 days or (ii) a default by the Guarantor or any
                    Restricted Subsidiary in the payment when due of any
                    portion of the principal under any such instrument or
                    instruments, and such unpaid portion exceeds $50,000,000
                    (or its foreign currency equivalent) individually or in
                    the aggregate and is not paid, or such default is not
                    cured or waived, within any grace period applicable
                    thereto, unless such Indebtedness is discharged within
                    30 days of the Guarantor or a Restricted Subsidiary
                    becoming aware of such default;

               f)   the Guarantor or any Significant Subsidiary pursuant to or
                    within the meaning of any Bankruptcy Law:

              (i)   commences a voluntary case;

              (ii)  consents to the entry of an
                    order for relief against it in an involuntary case;

              (iii) consents to the appointment of a Custodian of it or for all
                    or substantially all of its property;

              (iv)  makes a general assignment for the benefit of its
                    creditors; or

              (v)   admits in writing its inability to generally pay its debts
                    as such debts become due;

                                       22

          or takes any comparable action under any foreign laws relating to
insolvency;

               g)   an involuntary case or other proceeding shall be commenced
                    against the Guarantor or any Significant Subsidiary
                    seeking (i) liquidation, reorganization or other relief
                    with respect to it or its debts under Title 11 of the
                    Bankruptcy Code or any bankruptcy, insolvency or other
                    similar law now or hereafter in effect, or (ii) the
                    appointment of a trustee, receiver, liquidator,
                    custodian or other similar official with respect to it
                    or any substantial part of its property or (iii) the
                    winding-up or liquidation of the Guarantor or such
                    Significant Subsidiary; and such involuntary case or
                    other proceeding shall remain undismissed and unstayed
                    for a period of 60 days;

               h)   any representation or warranty made by the Guarantor herein
                    shall prove to have been incorrect in any material
                    respect when made or misleading in any material respect
                    when made because of the omission to state a material
                    fact and such incorrect or misleading representation is
                    and continues to be material and unremedied for a period
                    of 30 days after receipt by the Guarantor of written
                    notice thereof; provided, however, that if such
                    condition cannot be remedied within such 30-day period,
                    then the period within which to remedy such condition
                    shall be extended up to an additional 60 days, so long
                    as the Guarantor diligently pursues such remedy and such
                    condition is reasonably capable of being remedied within
                    such additional 60-day period.

     The grace periods set forth in Section 7.1(a) and (b) above shall not
affect in any way the right hereunder of any Beneficiary entitled to a payment
of any amount payable to it, or performance of any obligation, by the South
Point Lessee under any Operative Document to demand prompt payment thereof, or
performance thereof, by the Guarantor immediately upon any failure of the South
Point Lessee to pay or perform the same when it has become due (and, for the
avoidance of doubt, without regard to the existence of any cure or grace period
before such failure by the South Point Lessee becomes a Lease Event of
Default); provided, however, notwithstanding the foregoing, no Lease Event of
Default under Section 16(m) and no remedies under the Facility Lease may be
exercised until a Calpine Guaranty Event of Default has occurred and is
continuing.

     B.   Remedies. Subject to the last paragraph of Section 7.1, each
          Beneficiary shall be entitled to (a) all rights and remedies to
          which it may be entitled hereunder or at law, in equity or by
          statute and may proceed by appropriate court action to enforce the
          terms hereof and to recover damages for the breach hereof. Each and
          every remedy of the

                                       23

          Beneficiaries shall, to the extent permitted by law, be cumulative
          and shall be in addition to any other remedy now or hereafter
          existing at law or in equity. At the option of each Beneficiary and
          upon notice to the Guarantor, the Guarantor may be joined in any
          action or proceeding commenced by such Beneficiary against the South
          Point Lessee in respect of any Obligations and recovery may be had
          against the Guarantor in such action or proceeding or in any
          independent action or proceeding against the Guarantor, without any
          requirement such Beneficiary first assert, prosecute or exhaust any
          remedy or claim against the South Point Lessee. Notwithstanding any
          of the foregoing, if an Event of Default specified in clause (e) or
          (f) of Section 7.1 with respect to the Guarantor occurs, all
          monetary Obligations shall ipso facto become and be immediately due
          and payable without any declaration or other act on the part of the
          Owner Participant, the Owner Lessor, the Indenture Trustee or the
          Pass Through Trustee.

     C.   Subrogation. The Guarantor will not exercise any rights that it may
          acquire by way of subrogation under this Guaranty, by any payment
          made hereunder or thereunder or otherwise, until all of the
          Obligations and all other obligations of the South Point Lessee and
          the Guarantor owing to any of the Beneficiaries (or any other party)
          under the Operative Documents shall have been paid in full. If any
          amount shall be paid to the Guarantor on account of such subrogation
          rights at any time when all of the Obligations and such other
          obligations shall not have been paid in full, such amount shall be
          held in trust for the benefit of the Beneficiary to whom such
          Obligation or other obligation is payable and shall forthwith be
          paid to such Beneficiary to be credited and applied to such
          Obligation or other obligation, whether matured or unmatured, in
          accordance with the terms of the Operative Document under which such
          Obligation or other obligation arose. If (i) the Guarantor shall
          make payment to any Beneficiary of all or any part of the
          Obligations or other obligations and (ii) all the Obligations and
          such other obligations shall be paid and performed in full, such
          Beneficiary will, at the Guarantor's request and expense, execute
          and deliver to the Guarantor appropriate documents, without
          recourse, subject to Section 6 hereof, necessary to evidence the
          transfer by subrogation to the Guarantor of an interest in the
          Obligations and such other obligations resulting from such payment
          by the Guarantor.

     D.   Waiver of Demands, Notices, Etc.

               a)   Without limiting the last sentence of Section 7.1, the
                    Guarantor hereby unconditionally waives (i) notice of
                    any of the matters referred to in the second sentence of
                    Section 2.3 hereof; (ii) all notices which may be
                    required by statute, rule of law or otherwise, now or
                    hereafter in effect, to preserve any rights against the
                    Guarantor hereunder, including, without limitation, any
                    demand, proof or notice

                                       24

                    of non-payment of any Obligation; (iii) any right to the
                    enforcement, assertion or exercise of any right, remedy,
                    power or privilege under or in respect of the Facility Lease
                    (or under or in respect of any other agreement including any
                    Operative Document); (iv) notice of acceptance of this
                    Guaranty, demand, protest, presentment, notice of
                    default and any requirement of diligence; (v) any
                    requirement to exhaust any remedies or to mitigate any
                    damages resulting from default by the South Point Lessee
                    or any Person under the Facility Lease (or under any
                    other agreement including any Operative Document); and
                    (vi) any other circumstance whatsoever which might
                    otherwise constitute a legal or equitable discharge,
                    release or defense of a guarantor or surety, or which
                    might otherwise limit recourse against the Guarantor,
                    other than satisfaction in full of the Obligations.

               b)   This Guaranty is a continuing one and all of the
                    Obligations shall be conclusively presumed to have been
                    created in reliance hereon. No failure or delay on the
                    part of any Beneficiary in exercising any right, power
                    or privilege hereunder and no course of dealing among
                    the Guarantor, any Beneficiary or the South Point Lessee
                    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
                    or the exercise of any other right, power or privilege.
                    The rights, powers and remedies herein expressly
                    provided are cumulative and not exclusive of any rights,
                    powers or remedies which the Beneficiary would otherwise
                    have. No notice to or demand on the Guarantor in any
                    case shall entitle the Guarantor to any other further
                    notice or demand in similar or other circumstances or
                    constitute a waiver of the rights of any Beneficiary to
                    any other or further action in any circumstances without
                    notice or demand.

               c)   If a claim is ever made upon any Beneficiary for repayment
                    or recovery of any amount or amounts received in
                    payment or on account of any of the Obligations and any
                    of the Beneficiaries repays all or part of said amount
                    by reason of (a) any judgment, decree or order of any
                    court or administrative body having jurisdiction over
                    such Beneficiary or any of its property or (b) any
                    settlement or compromise of any such claim effected by
                    such Beneficiary with any such claimant (including the
                    South Point Lessee), then and in such event the
                    Guarantor agrees that any such judgment, decree, order,
                    settlement or compromise shall be binding upon it,
                    notwithstanding any revocation hereof or

                                       25

                    the cancellation of the Facility Lease or other instrument
                    evidencing any liability of the South Point Lessee, and
                    the Guarantor shall be and remain liable to the
                    aforesaid Beneficiaries hereunder for the amount so
                    repaid by or recovered from such Beneficiary to the same
                    extent as if such amount had never originally been
                    received by any such Beneficiary.

     E.   Costs and Expenses. The Guarantor agrees to pay on an After-Tax Basis
          any and all reasonable costs and expenses (including reasonable
          legal fees) incurred by any Beneficiary in enforcing its rights
          under this Guaranty.

     F.   Survival of Remedies and Subrogation Rights. The provisions of this
          Section 7 shall survive the term of this Guaranty and the payment
          in full of the Obligations and the termination of the Operative
          Documents.

VIII.   MISCELLANEOUS

     A.   Amendments and Waivers. No term, covenant, agreement or condition of
          this Guaranty may be terminated, amended or compliance therewith
          waived (either generally or in a particular instance, retroactively
          or prospectively) except by an instrument or instruments in writing
          executed by the Guarantor and consented to by the Beneficiaries.

     B.   Notices. Unless otherwise expressly specified or permitted by the
          terms hereof, all communications and notices provided for herein
          shall be in writing or by a telecommunications device capable of

          effective (a) upon personal delivery thereof, including, without
          limitation, by overnight mail or courier service, (b) in the case of
          notice by United States mail, certified or registered, postage
          prepaid, return receipt requested, upon receipt thereof, or (c) in
          the case of notice by such a telecommunications device, upon
          transmission thereof, provided such transmission is promptly
          confirmed by either of the methods set forth in clauses (a) or (b)

this Guaranty to such third party (whereupon the Guarantor shall be released
from all obligations under this Guaranty in connection with such transfer) upon
satisfaction of the following conditions:

          (i)   unless the Owner Participant shall have consented to such
     assignment, such transferee, or a party which unconditionally guarantees
     such transferee's obligations under the Operative Documents assigned to
     such transferee (A) shall have significant experience owning or operating

     the Ownership Interest of the South Point Lessee;

          (iii)   such transfer occurs (i) subsequent to the tenth year of the
     Facility Lease Term of the South Point Lessee and (ii) when the aggregate
     principal amount of the Lessor Notes is less than $50 million;

          (iv)   neither the transferee nor any Affiliate of the transferee
     shall be involved in any material litigation with the Owner Participant;

          (v)   the Rating Agencies shall have confirmed that after giving
     effect to such transfer, the Certificates (if then outstanding) and the
     transferee (or a party which guarantees such transferee's obligations
     under the Operative Documents assigned to such transferee) shall be rated
     at least Investment Grade (and not be on negative credit watch) by the
     Rating Agencies;

          (vi)   all the obligations of the South Point Lessee under the
     Operative Documents and the South Point Ground Lease shall remain in full
     force and

                                       27

     effect, the transferee shall assume all the obligations of the Guarantor
     under the Operative Documents pursuant to the Guarantor Assignment and
     Assumption Agreement and such Operative Documents as so assumed shall
     remain in full force and effect, and any guaranty of such transferee's
     obligations pursuant to this Section 8.4 shall be in a form satisfactory
     to the Owner Participant (it being acknowledged and agreed that any such
     guaranty which shall be in form and substance substantially similar to
     this Guaranty shall be deemed to be satisfactory to the Owner
     Participant); and

          (vii)   the Owner Participant, the Owner Lessor and, so long as the
     Lien on the Collateral Trust Indenture shall not have been terminated or
     discharged, the Indenture Trustee and the Pass Through Trustee shall have
     received an Opinion of Counsel as to the satisfaction of the conditions
     set forth in clause (vi) of this Section 8.4(b).

          inserted for purposes of convenience only and shall not be

          respect to any of the Obligations shall, if the statute of
          limitations in favor of the Guarantor against any Beneficiary
          shall have commenced to run, toll the running of such statute
          of limitations, and if the period of such statute of
          limitations shall have expired, prevent the operation of such
          statute of limitations.

     L.   Consent to Jurisdiction; Waiver of Trail by Jury; Process Agent.

               a)   The Guarantor (i) hereby irrevocably submits to the

                    State of New York, New York County (without prejudice to

                    States District

                                       29

                    Court for the Southern District of New York) and
                    to the nonexclusive jurisdiction of the United States
                    District Court for the Southern District of New York for
                    the purposes of any suit, action or other proceeding
                    arising out of this Guaranty, the Facility Lease, the other
                    Operative Documents, or the subject matter hereof or
                    thereof or any of the transactions contemplated hereby or
                    thereby brought by any of the Beneficiaries hereunder or
                    their successors or assigns; (ii) hereby irrevocably agrees
                    that all claims in respect of such action or proceeding may

                    not personally subject to the jurisdiction of the
                    above-named courts, that the suit, action or proceeding is
                    brought in an inconvenient forum, that the venue of the
                    suit, action or proceeding is improper or that this
                    Guaranty, the other Operative Documents, or the subject
                    matter hereof or thereof may not be enforced in or by such

                    HEREBY IRREVOCABLY WAIVES THE RIGHT TO DEMAND A TRIAL
                    BY JURY, IN ANY SUCH SUIT, ACTION OR OTHER PROCEEDING
                    ARISING OUT OF THIS GUARANTY, THE OTHER OPERATIVE
                    DOCUMENTS, OR THE SUBJECT MATTER HEREOF OR THEREOF OR
                    ANY OF THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY
                    BROUGHT BY ANY OF THE BENEFICIARIES HEREUNDER OR THEIR
                    SUCCESSORS OR ASSIGNS.

                    other legal process in any such action, suit or
                    proceeding in the State of New York for so long as any
                    obligation of the Guarantor shall remain outstanding
                    hereunder or under any of the other Operative Documents.

                    of such appointment and shall maintain such power of

                    obligation of the Guarantor shall remain outstanding
                    hereunder or under any of the Operative Documents.

                                       30

     M.   Agreement for Benefit of Parties Hereto. Nothing in this
          Guaranty, express or implied, is intended or shall be
          construed to confer upon, or to give to, any person
          other than the parties hereto and their respective
          successors and assigns, any right, remedy or claim under
          or by reason of this Guaranty or any covenant, condition
          or stipulation hereof; and the covenants, stipulations
          and agreements contained in this Guaranty are and shall
          be for the sole and exclusive benefit of the parties
          hereto and their respective successors and assigns. The
          Guarantor acknowledges that certain of the rights of the
          Owner Lessor hereunder have been or shall be assigned to
          and may be enforced by the Indenture Trustee pursuant to
          the terms of the Collateral Trust Indenture (excluding,
          among other things, rights to Excepted Payments), the
          Guarantor hereby consents to such assignment and the
          Guarantor agrees to render performance of such assigned
          obligations directly to the Indenture Trustee (as
          assignee of the Owner Lessor). The Guarantor agrees to
          make all payments which have been so assigned owing to
          the Owner Lessor under this Guaranty directly to the
          account of the Indenture Trustee to be specified to the
          Guarantor in writing, or to such other account specified
          in writing from time to time by the Indenture Trustee.

     N.   Termination of Guaranty. Upon the full payment and
          satisfaction of the Obligations and all of the
          Guarantor's obligations hereunder, this Guaranty shall
          terminate and shall be of no further effect.
          Nevertheless, this Guaranty shall continue to be
          effective or be reinstated, as the case may be, if at
          any time, any payment, or any part thereof, of any of
          the Obligations is rescinded or must otherwise be
          returned by any Beneficiary upon the insolvency,
          bankruptcy, dissolution, liquidation or reorganization
          of the South Point Lessee or otherwise, all as though
          such payment had not been made.

     O.   Additional Obligations. Upon the assumption by the South
          Point Lessee of the Lessor Notes in connection with a
          termination of the Facility Lease, as permitted therein,
          the obligation of the South Point Lessee to pay
          principal of, and Make-Whole Amount if any, and interest
          on the Lessor Notes, and amounts payable by it to the
          Indenture Trustee under the Collateral Trust Indenture,
          shall thereupon become Obligations for all purposes of
          this Guaranty, and the Guarantor shall therefor execute
          and deliver to the Indenture Trustee such further
          guaranties, instruments and documents as the Indenture
          Trustee may reasonably request in order to more fully
          effectuate the Guarantor's unconditional guaranty of
          such additional Obligations.

     P.   Miscellaneous Provisions. The payment obligations of the
          Guarantor hereunder shall rank pari passu with all
          other senior unsecured indebtedness of the Guarantor for
          borrowed money.

                                       31
