                                    GUARANTEE

            SECTION 2.01. Unconditional Guarantee.

            The Guarantor hereby unconditionally guarantees to each Holder of a
Security authenticated by the Trustee and to the Trustee and its successors and
assigns that: the principal of, premium thereon (if any) and interest on the
Securities of each Series will be promptly paid in full when due, subject to any
applicable grace period, whether at maturity, by acceleration or otherwise, and
interest on the overdue principal and interest on any overdue interest on the
Securities of each Series and all other obligations of the Company to the
Holders or the Trustee hereunder or under the Indenture or the Securities of
such Series will be promptly paid in full or performed, all in accordance with
the terms hereof and thereof. The Guarantor hereby agrees that its obligations
hereunder shall be unconditional, irrespective of the validity, regularity or
enforceability of the Securities of each Series or of the Indenture, the absence
of any action to enforce the same, any waiver or consent by any Holder of the
Securities or any Series with respect to any provisions hereof, of the Indenture
or of the Securities, the recovery of any judgment against the Company, any
action to enforce the same or any other circumstance which might otherwise
constitute a legal or equitable discharge or defense of the Guarantor. The
Guarantor hereby waives diligence, presentment, demand of payment, filing of
claims with a court in the event of insolvency or bankruptcy of the Company, any
right to require proceeding first against the Company, protest, notice and all
demands whatsoever and covenants that the Guarantee will not be discharged
except by complete performance of the obligations contained in the Indenture and
the Securities of each Series. If any Holder or the Trustee is required by any
court or otherwise to return to the Company or the Guarantor, or any custodian,
trustee, liquidator or other similar official acting in relation to the Company
or the Guarantor, any amount paid by the


                                       4
<PAGE>   8
Company or the Guarantor to the Trustee or such Holder, the Guarantee, to the
extent theretofore discharged, shall be reinstated in full force and effect. The
Guarantee constitutes a guarantee of payment and not of collection.

            SECTION 2.02. Execution of Guarantee.

            To further evidence the Guarantee to the Holders, the Guarantor
hereby agrees to execute a Guarantee substantially in the form of Exhibit A
hereto, to be endorsed on and made a part of each Security ordered to be
authenticated and delivered by the Trustee. The Guarantor hereby agrees that its
Guarantee set forth in Section 2.01 shall remain in full force and effect
notwithstanding any failure to endorse on each Security a Guarantee. Each such
Guarantee shall be signed on behalf of the Guarantor by its Chairman of the
Board, its President or one of its Vice Presidents prior to the authentication
of the Security on which it is endorsed, and the delivery of such Security by
the Trustee, after the authentication thereof hereunder, shall constitute due
delivery of such Guarantee on behalf of the Guarantor. Such signature upon the
Guarantee may be a manual or facsimile signature of such officer and may be
imprinted or otherwise reproduced on the Guarantee, and in case such officer who
shall have signed the Guarantee shall cease to be such officer before the
Security on which Guarantee is endorsed shall have been authenticated and
delivered by the Trustee or disposed of by the Company, the Security
nevertheless may be authenticated and delivered or disposed of as though the
Person who signed the Guarantee had not ceased to be such officer of the
Guarantor.

            SECTION 2.03. Subordination of Subrogation and Other Rights.

            The Guarantor hereby agrees that any claim against the Company that
arises from the payment, performance or enforcement of the Guarantor's
obligations under the Guarantee or the Indenture, including, without limitation,
any right of subrogation, shall be subject and subordinate to, and no payment
with respect to any such claim of the Guarantor shall be made before, the
payment in full in cash of all outstanding Securities of each Series in
accordance with the provisions provided therefor in the Indenture.

            SECTION 2.04. Termination of Guarantee with Respect to Series.

            If all outstanding Securities of a Series are paid or discharged by
the Company pursuant to the Indenture, or if the Company otherwise terminates
its obligations with respect to all Securities of such Series pursuant to the
Indenture (including by defeasance thereof), then the Guarantee with respect to
the Securities of such Series and this Guarantee Agreement insofar as it relates
to the Securities of such Series, shall also and concurrently terminate.

                                  ARTICLE THREE

              CONSOLIDATION, MERGER, CONVEYANCE, TRANSFER OR LEASE

related transactions consolidate with or merge with or into any other
corporation or sell, assign, convey, transfer or lease or otherwise dispose of
all or substantially all of its properties and assets to any Person or group of
affiliated Persons, unless:


                                       5
<PAGE>   9
             (i) 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 (the "Successor Corporation") shall be a corporation
     organized and existing under the laws of the United States or any State
     thereof or the District of Columbia and shall expressly assume, by an
     agreement supplemental hereto, executed and delivered to the Trustee, in
     form reasonably satisfactory to the Trustee, all the obligations of the
     Guarantor under this Agreement;

             (ii) immediately after giving effect to such transaction, no
     Default shall have occurred and be continuing;

             (iii) the Guarantor shall have delivered, or caused to be
     delivered, to the Trustee an Officers' Certificate and, as to legal
     matters, an Opinion of Counsel, each in form reasonably satisfactory to the
     Trustee, each stating that such consolidation, merger, sale, assignment,
     conveyance, transfer, disposition or lease and such supplemental indenture
     comply with this Agreement and that all conditions precedent herein
     provided for relating to such transaction have been complied with;

            Notwithstanding the foregoing paragraph (ii), any Restricted
Subsidiary, the Guarantor or any Wholly Owned Subsidiary or Wholly Owned
Subsidiaries may consolidate with or merge with or into the Guarantor or any
Wholly Owned Subsidiary and no violation of this Section shall be deemed to have
occurred as a consequence thereof, as long as the requirements of paragraphs (i)
and (iii) are satisfied in connection therewith.

            SECTION 3.02. Successor Substituted.

             Upon any such consolidation or merger, or any sale, assignment,
conveyance, transfer, disposition or lease of all or substantially all of the
properties or assets of the Guarantor in accordance with Section 3.01, the
Successor Corporation shall succeed to and be substituted for the Guarantor
under this Agreement, and the Guarantor shall (except in the case of a lease)
thereupon be released from all obligations hereunder and under this Agreement
and the Guarantor, as the predecessor corporation, may thereupon or at any time
thereafter be dissolved, wound up or liquidated.

             SECTION 3.03. Assignment to the Guarantor of the Company's
Obligations.

            It is acknowledged that, pursuant to Section 4.3 of the Indenture,
the Company may assign its obligations under any Series of Securities and the
Indenture to the Guarantor or any Subsidiary of the Guarantor in accordance with
such Section 4.3 and, if the Company assigns its obligations to the Guarantor in
accordance with such Section 4.3 with respect to any Series of Securities, all
Guarantees of outstanding Securities of such Series shall automatically
terminate and be discharged.

<PAGE>   10
                                  ARTICLE FOUR

                                   AMENDMENTS

            SECTION 4.01. Amendments Without Consent of Holders.

            The Guarantor, when authorized by a Board Resolution, and the
Trustee may enter into one or more agreements, in form satisfactory to the
Trustee, without notice to or the consent of any Securityholder for any of the
following purposes:

             (1) to evidence the succession of another corporation to the
Guarantor and the assumption by any such successor of the covenants of the
Guarantor herein; or

             (2) to add to the covenants of the Guarantor for the benefit of the
Holders of all or any Series of Securities, or to surrender any right or power
herein conferred upon the Guarantor; or

             (3) to comply with Article Three; or

             (4) to cure any ambiguity, to correct or supplement any provision
herein which may be inconsistent with any other provision herein, or to make any
other provisions with respect to matters or questions arising under this
Agreement; provided such action shall not adversely affect the interests of the
Holders in any material respect.

            SECTION 4.02. Amendments With Consent of Holders.

            The Guarantor, when authorized by a Board Resolution, and the
Trustee may enter into an amendment to this Agreement for the purpose of adding
any provisions to or changing in any manner or eliminating any of the provisions
of this Agreement or of modifying in any manner the rights of the Holders of
Securities of any Series under this Agreement with the written consent of the
Holders of a majority in principal amount of the Securities of each Series
affected by such amendment. However, without the consent of each Securityholder
affected, an amendment under this Section may not:

            (1) modify Article Two or the definitions used in Article
Two in a manner which adversely affects the Holders of Outstanding Securities in
any material respect, or

            (2) modify any of the provisions of this Section 4.02,
except to increase any such percentage or to provide that certain other
provisions of this Agreement cannot be modified or waived without the consent of
the Holder of each Outstanding Security affected thereby.

            An amendment that changes or eliminates any covenant or other
provision of this Agreement which has expressly been included solely for the
benefit of one or more particular Series of Securities, or that modifies the
rights of the Holders of Securities of such Series with respect to such covenant
or other provision, shall be deemed not to affect the rights under this
Agreement of the Holders of Securities of any other Series.


                                       7
<PAGE>   11
            It shall not be necessary for any Act of Holders under this Section
4.02 to approve the particular form of any proposed amendment, but it shall be
sufficient if such Act shall approve the substance thereof.

            SECTION 4.03. Execution of Amendments.

            In executing any amendment permitted by this Article Four, the
Trustee shall be entitled to receive, and shall be fully protected in relying
upon, an Opinion of Counsel stating that the execution of such amendment is
authorized or permitted by this Agreement. The Trustee may, but shall not be
obligated to, enter into any such amendment which affects the Trustee's own
rights, duties or immunities under this Agreement or otherwise.

            SECTION 4.04. Effect of Amendments.

            Upon the execution of any amendment under this Article Four, this
Agreement shall be modified in accordance therewith, and such amendment shall
form a part of this Agreement for all purposes; and every Holder of Securities

             SECTION 5.02. Limitation on Sale/Leaseback Transactions.

             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
Securities pursuant to Section 5.03 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 5.03 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, 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.

            SECTION 5.03. Limitation on Liens.

             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 of issuance of
any Series of Securities pursuant to the Indenture 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,


                                       9
<PAGE>   13
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 of the issuance of such series of
Securities (other than Liens relating to Indebtedness or other obligations being
repaid or Liens that are otherwise extinguished with the proceeds of any
offering of Securities pursuant to this Indenture); (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 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);
and (h) Liens by which the Securities are secured equally and ratably with other
Indebtedness pursuant to this Section 5.03; in any such case without effectively
providing that the Securities 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 5.02 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.

            The Guarantor may omit in any particular instance to comply with any
covenant or condition set forth in Sections 5.02 and 5.03, inclusive, if before
or after the time for such compliance the Holders of at least 50% in principal
amount of the Securities of each Series at the time outstanding, shall either
waive such compliance in such instance or generally waive


                                       10
<PAGE>   14
compliance with such covenant or condition, but no such waiver shall extend to
or affect such covenant or condition except to the extent so expressly waived,
and, until such waiver shall become effective, the obligations of the Guarantor
and the duties of the Trustee in respect of any such covenant or condition shall
remain in full force and effect.

            SECTION 5.05. Reports by Guarantor.

            (a) The Guarantor shall file with the Trustee, within 15 days after
the Guarantor is required to file the same 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 from time to time by rules and
regulations prescribe) which the Guarantor is required to file with the SEC
pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934,
as amended and shall otherwise comply with Section 314(a) of the Trust Indenture

                                FORM OF GUARANTEE

            For value received, CALPINECORPORATION, a Delaware corporation
(including any successor under the Guarantee Agreement referred to in the
Security upon which this Guarantee is endorsed, the "Guarantor") hereby
unconditionally guarantees to the Holder of the Security upon which this
Guarantee is endorsed, and to the Trustee and its successors and assigns on
behalf of such Holder, that: the principal of, premium thereon (if any) and
interest on such Security will be promptly paid in full when due, subject to any
applicable grace period, whether at maturity, by acceleration or otherwise, and
interest on the overdue principal and interest on any overdue interest on such
Security and all other obligations of the Company to the Holder of such Security
or the Trustee or under the Indenture will be promptly paid in full or
performed, all in accordance with the terms hereof and thereof.

            The Guarantor hereby agrees that its obligations hereunder shall be
unconditional, irrespective of the validity, regularity or enforceability of the
Security upon which this Guarantee is endorsed or of the Indenture, the absence
of any action to enforce the same, any waiver or consent by the Holder of such
Security or the Trustee with respect to any provisions hereof or of the
Indenture, the Guarantee Agreement or the Securities, the recovery of any
judgment against the Company, any action to enforce the same or any other
circumstance which might otherwise constitute a legal or equitable discharge or
defense of the Guarantor.

            The Guarantor hereby waives diligence, presentment, demand of
payment, filing of claims with a court in the event of insolvency or bankruptcy
of the Company, any right to require proceeding first against the Company,
protest, notice and all demands whatsoever and covenants that this Guarantee
will not be discharged except by complete performance of the obligations
contained in the Indenture and the Security upon which this Guarantee is
endorsed. This is a guarantee of payment and not of collection.

            If the Holder of such Security or the Trustee is required by any
court or otherwise to return to the Company or the Guarantor, or any custodian,
trustee, liquidator or other similar official acting in relation to the Company
or the Guarantor, any amount paid by the Company or the Guarantor to the Trustee
or such Holder, the Guarantee, to the extent theretofore discharged, shall be
reinstated in full force and effect.

            The Guarantor hereby agrees that any claim against the Company that
arises from the payment, performance or enforcement of the Guarantor's
obligations under the Guarantee or the Indenture, including, without limitation,
any right of subrogation, shall be subject and subordinate to, and no payment
with respect to any such claim of the Guarantor shall be made before, the
payment in full in cash of the Security upon which this Guarantee is endorsed in
accordance with the provisions provided therefor in the Indenture.

            All capitalized terms used without definition in this Guarantee
shall have the respective meanings assigned to such terms in the Guarantee
Agreement.
