the termination of this Agreement or the Closing Date, the Purchasers will take

reasonable to do so, will not take or fail to take any action that could
reasonably be expected to result in the non-fulfillment of any such condition.

becomes aware of any fact or condition that causes or constitutes a breach of
such Purchaser's representations and warranties as of the date of this

representations or warranties hereunder of the Purchaser for purposes of the
closing conditions set forth in this Agreement or (ii) limit or otherwise affect
the remedies available hereunder to the party receiving such notice; provided,
however, that if following such notice, the Sellers shall proceed with the

         9.1 Representations, Warranties and Covenants. Except as expressly
otherwise provided, each Seller, severally and not jointly with any other
Seller, represents, warrants and covenants that as of the date of this Agreement
and, except as otherwise expressly provided, as of the Closing Date:

         (a) (i) OGII Trust has filed when due all Tax Returns that are required
to be filed by it on or before the Closing Date; and (ii) OGII Trust has timely
paid all Taxes imposed on or incurred by it as shown on such Tax Returns as
being owed. Neither the Sellers nor OGII Trust has been notified in writing of
any claim or potential claim by any tax authority for unpaid Taxes relating to
events or periods before the Closing Date. There have not been any tax audits
with respect to, and no claims have been made by, OGII Trust or the Sellers
under any tax indemnities in the Facility Lease. The Sellers are not foreign
persons within the meaning of Section 1445 of the Code. The Constellation
Sellers, but not TriCon, represent and warrant that neither the Constellation
Sellers nor, to their Knowledge, OGII Trust, have taken a position on any Tax
Return that is inconsistent with (x) the tax treatment of OGII Trust as a
partnership or (y) the position that the Facility Lease is a true lease for all
federal and California state and local income tax purposes.

         (b) No "check-the-box" elections have been filed pursuant to Treasury
Regulations ss. 301.7701-3 for OGII Trust within the 60-month period ending on
the Closing Date.

         (c) True and complete copies of all Tax Returns and all schedules
thereto filed by, or on behalf of, OGII Trust for all prior taxable years have
been (or will be upon request) made available to the Purchasers for inspection.

         9.2 Tax Matters.

         (a) Transfer Taxes. The Purchasers shall pay all sales, use, transfer,
stock transfer and other similar taxes and fees ("Transfer Taxes") if any,
arising out of or in connection with the sale of the Purchased Interests
pursuant to this Agreement.

         (b) Pre-Closing Income Taxes and Overlap Period Income Taxes. Each
Seller shall be responsible for all Pre-Closing federal, state and local income
taxes ("Income Taxes") and for Overlap Period Income Taxes to the extent they
relate to events or periods through 12:00 a.m. (California time) on the Closing
Date. Each Seller shall prepare and file, or cause to be filed, Tax Returns for
Pre-Closing Income Taxes. The Purchasers shall prepare and file Tax Returns for
Overlap Period Income Taxes, and will supply the Sellers with a draft of any
such returns and a written request for payment of each Sellers share of such
Income Taxes. The Purchasers preparation of any such Tax Returns shall be
subject to the Sellers' approval, which shall not be unreasonably withheld or
delayed. Payments of the Sellers' share must be made to the Purchasers by wire
transfer within thirty (30) business days after such request. Liability for
Overlap Period Income Taxes will be allocated between the Sellers and the
Purchasers on a

                                       23

closing of the books method. The parties agree to cooperate with one another
with respect to preparing and filing Tax Returns.

         (c) Refunds. Any refund or credit of Pre-Closing Taxes or Overlap
Period Income Taxes paid by the Sellers shall be for the benefit of the Sellers.
The Purchasers shall pay any such refund to the Sellers within thirty (30) days
after the Purchasers or OGII Trust receive such refund or actually realize the
benefit of such credit.

         (d) Contests. The Purchasers agree that, in the event the Purchasers or
OGII Trust receive notice in writing of any examination, claim, settlement,
proposed adjustment, administrative or judicial proceeding, or other matter
related to any Pre-Closing Income Taxes or Overlap Period Income Taxes for which
the Sellers may be liable under Section 9.2(b), the Purchasers will notify the
Sellers in writing promptly after receipt of such notice. The Purchasers will be
entitled to control any tax contest, except to the extent that responsibility
for the disputed tax liability falls solely on the Sellers; provided, however,
that if responsibility for the disputed tax liability falls solely on the
Sellers but the contest involves issues that may recur on a later tax Return of
OGII Trust or the Purchasers with respect to OGII Trust, the Purchasers will
control such tax contest. The Sellers shall notify the Purchasers in writing
within thirty (30) business days following receipt of the notice from the
Purchasers described in this paragraph 9.2(c) that the Sellers assume control
over the contest if so entitled. Each party will bear its own expenses, and the
controlling party will keep the other party informed of developments in the
case. The controlling party or parties shall attempt in good faith to ensure
that the noncontrolling party or parties have the opportunity to attend meetings
with tax officials and to comment on any written submissions before they are
submitted. Suggestions by the noncontrolling party or parties about the conduct
of the contest will be considered in good faith by the controlling party, but
the controlling party will make the ultimate decision on whether, how long and
in what manner to contest. The obligations of the Sellers under this Section
9.2(d) shall be subject to any restrictions or limitations placed upon the
Sellers under the Leveraged Lease Documents unless such restrictions or
limitations (if any) are waived.

         (e) Information. In connection with preparing any Tax Return or
preparing for any audit or other examination by any taxing authority or any
judicial or administrative proceedings relating to liability for Income Taxes,
the Sellers, the Purchasers and OGII Trust will provide the relevant portion of
any information, records or documents relating to Income Taxes as may be
reasonably requested by another Party. The Sellers will not destroy any records
related to OGII Trust for tax periods commencing before the Closing Date for a
period of seven (7) years following the date thereof without first giving notice
to and obtaining the written consent of the Purchasers (whose consent shall not
be unreasonably withheld).

                                    SURVIVAL

         10.1 Survival of Representations, Warranties, Covenants and Agreements.
The representations, warranties, covenants and agreements of the Sellers and the
Purchasers contained in this Agreement (other than (i) the covenants and
agreements contained in Articles 10, 11 and 12, which covenants and agreements
shall survive in accordance with their terms, (ii) the covenants and agreements
in Section 14.5, which covenants and agreements shall survive for

                                       24

a period of two (2) years after the Closing, (iii) the representations and
warranties contained in Sections 3.1(a), (b), (c), (e) and (g); 4.1; 4.2; 4.3
and 4.6; which covenants, representations and warranties shall survive
indefinitely after the Closing, and (iv) the covenants and agreements contained
in Article 9, which covenants and agreements shall survive for the applicable
statute of limitations; provided, however, that claims first asserted in writing
within the applicable period (whether or not the amount of any such claim has
become ascertainable within such period) shall not thereafter be time barred.

         10.2 No Other Representations. Notwithstanding anything to the contrary
contained in this Agreement, each party agrees that the Sellers are making no
representation or warranty whatsoever, express or implied, except those
representations and warranties contained in Section 3.1 and in any certificate
delivered pursuant to Article 7. In particular, the Sellers make no
representation or warranty to the Purchasers with respect to (i) the cost of
operating the Ormesa II Facility or the revenues to be derived therefrom; (ii)
the accuracy of any forecast, study or projection relating to the business or
condition of OGII Trust; (iii) whether the Ormesa II Facility can be financed;
(iv) the ultimate feasibility or economic worth of the Ormesa II Facility; or
(v) the effect on the business or condition of OGII Trust of the sale of the
Purchased Interests to the Purchasers. With respect to any projection or
forecast delivered by or on behalf of the Sellers to the Purchasers, the
Purchasers acknowledge that (i) there are uncertainties inherent in attempting
to make such projections, studies and forecasts, (ii) they are familiar with
such uncertainties and (iii) they are taking full responsibility for making
their own evaluation of the adequacy and accuracy of all such projections,
studies and forecasts furnished to them.

fullest extent permitted by Law, indemnify, defend and hold harmless, on an
After-Tax Basis, the Purchasers and their Affiliates and the respective
officers, directors, employees and shareholders of the foregoing, and their
successors and assigns (the "Purchasers Indemnified Parties") from, against and
with respect to any claim, liability, obligation or Loss, of any kind or
character, suffered, incurred or sustained by the Purchasers or any of the
foregoing or to which it or they become subject, arising out of or in any manner
incident, relating or attributable to:

                  (i) any inaccuracy in any representation or breach of warranty
of such Seller contained in this Agreement or in any certificate, instrument of
transfer or other document or agreement executed by any Seller in connection
with this Agreement;

                  (ii) any failure by any of the Sellers to perform or observe,
or to have performed or observed, in full, any covenant, agreement or condition
to be performed or observed by any of them under this Agreement or under any
certificates or other documents or agreements executed by any Seller in
connection with this Agreement; and

                                       25

                  (iii) any events, occurrences or conditions relating to the
Purchased Interests, in respect of all periods prior to the Closing but
excluding any events, occurrences or conditions caused by the Purchasers or
their Affiliates.

         (b) The Purchasers shall, to the fullest extent permitted by Law,
jointly and severally, indemnify, defend and hold harmless, on an After-Tax
Basis, the Sellers, and their Affiliates and the respective partners, officers,
directors, employees and shareholders of the foregoing, and their successors and
assigns (the "Sellers Indemnified Parties") from, against and with respect to
any claim, liability, obligation judgment or Loss, of any kind or character,
suffered, incurred or sustained by the Sellers or any of the foregoing or to
which they become subject, arising out of or in any manner incident, relating or
attributable to:

                  (i) any inaccuracy in any representation or breach of warranty
of the Purchasers contained in this Agreement or in any certificate, instrument
of transfer or other document or agreement executed by the Purchasers in
connection with this Agreement;

                  (ii) any failure by the Purchasers to perform or observe, or
to have performed or observed, in full, any covenant, agreement or condition to
be performed or observed by it under this Agreement or under any certificates or
other documents or agreements executed by the Purchasers in connection with this
Agreement; and

                  (iii) any events, occurrences or conditions relating to the
Purchased Interests, OGII Trust, or the Ormesa II Facility in respect of all
periods after the Closing.

         (c) Notwithstanding anything herein to the contrary, no indemnification
shall be available to the Purchasers Indemnified Parties under Section 11.1(a)
hereof or to the Sellers Indemnified Parties under Section 11.1(b) hereof:

                  (i) unless, with respect to any claim, the Loss involves an
amount in excess of $25,000.00; and

                  (ii) unless the aggregate amount of Damages that would
otherwise be subject to indemnification with respect to such claim and all prior
claims exceeds $250,000.00 (such amount, the "Threshold Amount"), in which case
the party(ies) entitled to such indemnification shall be entitled to receive all
amounts in excess of the Threshold Amount.

         (d) Notwithstanding anything herein to the contrary, no Seller shall
have any obligation to indemnify any Purchasers Indemnified Party for any Losses
pursuant to Section 11.1(a) hereof, and the Purchasers shall have no obligation
to indemnify any Sellers Indemnified Party for any Losses pursuant to Section
11.1(b) hereof, in each case to the extent such Losses arise from the willful
misconduct or gross negligence of any Purchaser or the Sellers, as applicable.

         (e) Notwithstanding anything herein to the contrary, the maximum
aggregate liability of the Constellation Sellers and Constellation Power, Inc.
to the Purchasers Indemnified Parties under this Agreement shall not exceed an
amount equal to $50,000.00 and the maximum aggregate liability of TriCon and
Verizon to the Purchasers Indemnified Parties under this Agreement shall not
exceed an amount equal to $50,000.00; provided that the limitations

                                       26

contained in this clause shall not apply to Damages arising from a breach of the
representations in Sections 3.1(a), 3.1(b), and 3.1(e).

         11.2 Method of Asserting Claims. All claims for indemnification by any
Indemnified Party under this Section 11.2 will be asserted and resolved as
follows:

         (a) In the event any claim or demand in respect of which an Indemnified
Party might seek indemnity under Section 11.1 is asserted against or sought to
be collected from such Indemnified Party by a Person other than the Sellers,
Constellation Power, Inc., the Purchasers or any Affiliate of the Sellers or the
Purchasers (a "Third Party Claim"), the Indemnified Party shall deliver a Claim
Notice with reasonable promptness (and in any event within 60 days of becoming
aware of the basis for such Claim Notice) to the Indemnifying Party.

                  (i) If the Indemnifying Party notifies the Indemnified Party
within the Dispute Period that the Indemnifying Party desires to defend the
Indemnified Party with respect to the Third Party Claim pursuant to this Section
11.2(a), and confirms its liability with respect thereto, then the Indemnifying
Party will have the right to defend, at the sole cost and expense of the
Indemnifying Party, such Third Party Claim by all appropriate proceedings, which
proceedings will be vigorously and diligently prosecuted by the Indemnifying
Party, with counsel reasonably acceptable to the Indemnified Party, to a final
conclusion or will be settled at the discretion of the Indemnifying Party
(subject to the limitations set forth below). From and after the Indemnifying
Party's delivery of the notice referred to in the first sentence of this Section
11.2(a)(i), the Indemnifying Party will have full control of such defense and
proceedings, including any settlement thereof; provided, that the Indemnifying
Party may not settle or compromise any Third Party Claim in any manner that
results in any continuing liability or obligation for the Indemnified Party or
any admission of liability or wrongdoing by the Indemnified Party, without, in
any such case, the prior written consent of the Indemnified Party, which will
not be unreasonably withheld. If requested by the Indemnifying Party, the
Indemnified Party will, at the sole cost and expense of the Indemnifying Party,
cooperate with the Indemnifying Party and its counsel in contesting any Third
Party Claim that the Indemnifying Party elects to contest, or, if appropriate
and related to the Third Party Claim in question, in making any counterclaim
against the Person asserting the Third Party Claim, or any cross-complaint
against any Person (other than the Indemnified Party or any of its Affiliates).
Notwithstanding the foregoing, the Indemnified Party may take over the control
of the defense or settlement of a Third Party Claim at any time if it
irrevocably waives its right to indemnity under Section 11.1 with respect to
such Third Party Claim. Should the Indemnifying Party have interests that
diverge materially from those of the Indemnified Party, the Indemnified Party
shall have the right to request separate counsel from that representing the
Indemnifying Party, the expenses of such separate representation to be paid by
the Indemnifying Party.

                  (ii) If the Indemnifying Party fails to notify the Indemnified
Party within the Dispute Period that the Indemnifying Party desires to defend
the Third Party Claim pursuant to Section 11.2(a), or if the Indemnifying Party
gives such notice but fails to prosecute vigorously and diligently or settle the
Third Party Claim, then the Indemnified Party will have the right to defend, at
the sole cost and expense of the Indemnifying Party, the Third Party Claim by
all appropriate proceedings, which proceedings will be vigorously and diligently
prosecuted by the Indemnified Party to a final conclusion or will be settled at
the discretion of the

                                       27

Indemnified Party (with the consent of the Indemnifying Party, which consent
will not be unreasonably withheld). The Indemnified Party will have full control
of such defense and proceedings, including (except as provided in the
immediately preceding sentence) any settlement thereof; provided, that if
requested by the Indemnified Party, the Indemnifying Party will, at the sole
cost and expense of the Indemnifying Party, cooperate with the Indemnified Party
and its counsel in contesting any Third Party Claim which the Indemnified Party
is contesting, or, if appropriate and related to the Third Party Claim in
question, in making any counterclaim against the Person asserting the Third
Party Claim, or any cross-complaint against any Person (other than the
Indemnified Party or any of its Affiliates).

                  (iii) If the Indemnifying Party notifies the Indemnified Party
that it does not dispute its liability to the Indemnified Party with respect to
the Third Party Claim under Section 11.1 or fails to notify the Indemnified
Party within the Dispute Period whether the Indemnifying Party disputes its
liability to the Indemnified Party with respect to such Third Party Claim, the
Damages arising from such Third Party Claim will be conclusively deemed a
liability of the Indemnifying Party under Section 11.1 and the Indemnifying
Party shall pay the amount of such Damages to the Indemnified Party on demand
following the final determination thereof. If the Indemnifying Party has timely
disputed its liability with respect to such claim, the Indemnifying Party and
the Indemnified Party will proceed in good faith to negotiate a resolution of
such dispute, and if not resolved through negotiations within the Resolution
Period, the Indemnified Party shall be entitled to seek such remedies against
the Indemnifying Party as may then be available to it under this Agreement and
applicable Laws.

         (b) In the event any Indemnified Party should have a claim under
Section 11.1 against any Indemnifying Party that does not involve a Third Party
Claim, the Indemnified Party shall deliver an "Indemnity Notice" with reasonable
promptness (and in any event within 60 days of becoming aware of the basis for
such Indemnity Notice) to the Indemnifying Party. If the Indemnifying Party
notifies the Indemnified Party that it does not dispute the claim or the amount
of Loss therefrom described in such Indemnity Notice or fails to notify the
Indemnified Party within the Dispute Period that it disputes the claim described
in the Indemnity Notice, the Loss in the amount specified in the Indemnity
Notice will be conclusively deemed a liability of the Indemnifying Party under
Section 11.1 and the Indemnifying Party shall pay the amount of such Loss to the
Indemnified Party on demand. If the Indemnifying Party has disputed its
liability with or the amount of the Loss therefrom respect to such claim, such
dispute shall be resolved in accordance with the provisions of Article 12
hereof.

         11.3 Exclusivity. After the Closing, to the extent permitted by
applicable Laws, and except in the case of fraud, gross negligence or willful
misconduct, the indemnities set forth in this Article 11 shall be the exclusive
remedies of the Purchasers and the Sellers and their respective officers,
directors, employees, agents and Affiliates due to misrepresentation, breach of
warranty, nonfulfillment or failure to be performed of any covenant or agreement
contained in this Agreement or any events, occurrences or conditions relating to
the Ormesa II Facility, and the parties shall not be entitled to a rescission of
this Agreement or to any further indemnification rights or claims of any nature
whatsoever in respect thereof, all of which the parties hereto hereby waive;
provided, however, that the foregoing provision shall not limit or restrict the
availability of specific performance or other injunctive or equitable relief
(other than rescission)

                                       28

to the extent that specific performance or such other relief would otherwise be
available to a party under this Agreement.

         11.4 Notification by the Sellers of Certain Matters. The Sellers may,
at the Closing, notify the Purchasers in one or more of the certificates to be
delivered pursuant to Section 7.3, in reasonable detail of any representation or
warranty of any of the Sellers that was not true and accurate as of the date of
this Agreement or as of the Closing or of any covenant of any of the Sellers
that has not been performed and complied with and, if the Purchasers shall in
their sole discretion nevertheless elect to close under this Agreement, none of
the matters set forth in such certificate shall be deemed to be an inaccuracy in
or breach of the specific representations and warranties or covenants of the
Sellers so modified for purposes of, and the Purchasers shall not be entitled to
be indemnified as to any of such specific representations, warranties and
covenants in the form prior to their modification pursuant to, this Article 11.

                                   ARTICLE 12
                               DISPUTE RESOLUTION

         In the event an action, dispute, claim, counterclaim or controversy
("Dispute") arises between the parties arising out of or relating to this
Agreement, the aggrieved party shall promptly notify the other party of the
Dispute within ten (10) Business Days after such Dispute arises. If the parties
have failed to resolve the Dispute within ten Business Days after delivery of
such notice, each party shall, within five (5) Business Days thereafter,
nominate a senior officer of its management to meet to attempt to resolve the
Dispute. The senior officers shall meet within twenty (20) Business Days after
their nomination. If the matter has not been resolved within fourteen (14) days
after the meeting of the senior executives, either party may pursue any and all
available legal remedies, unless the parties mutually agree to an alternative
dispute resolution procedure.

                                   ARTICLE 13
                                   TERMINATION

         13.1 Termination. This Agreement may be terminated, and the
transactions contemplated hereby may be abandoned by written notice from the
terminating party to the non-terminating party (the date of such termination
being sometimes referred to as the "Termination Date"):

         (a) at any time before the Closing, by mutual written agreement of the
Sellers and the Purchasers; or

         (b) at any time before the Closing, by either any Seller or the
Purchasers, in the event that any Order or Law becomes effective restraining,
enjoining, or otherwise prohibiting or making illegal the consummation of any of
the transactions contemplated by this Agreement, upon notification of the
non-terminating party by the terminating party; or

         (c) at any time before the Closing, by any Seller if either Purchaser
shall be in material breach with respect to the due and timely performance of
any of its covenants or agreements contained herein and such breach has not been
waived, or if any of the representations and warranties of the Purchasers
contained in Article 4 are untrue, inaccurate or

                                       29

breached in any material respect as of the Closing, and such breach or untrue or
inaccurate representation or warranty, if capable of being cured, has not been
cured or made true by the Purchasers within twenty (20) days following receipt
by the Purchasers of written notice thereof or has not been waived by the
Sellers; or

         (d) at any time before the Closing, by the Purchasers if a Seller shall
be in material breach with respect to the due and timely performance of any of
its respective covenants or agreements contained herein and such breach has not
been waived, or if any of the representations and warranties of Sellers
contained in Article 3 are untrue, inaccurate or breached in any material
respect as of the Closing, and such breach or untrue or inaccurate
representation or warranty, if capable of being cured, has not been cured or
made true by the Sellers within twenty (20) days following receipt by the
Sellers of written notice thereof or has not been waived by the Purchasers; or

         (e) at any time after March 31, 2002, by the Sellers or the Purchasers
if the Closing shall not have occurred on or before such date by reason of the
failure to comply with the requirement of Section 7.10 and Section 8.10; or

         (f) at any time after March 31, 2002, by the Sellers or the Purchasers
if the Closing shall not have occurred on or before such date and such failure
to consummate is not caused by a breach of this Agreement by the terminating
party.

         13.2 Effect of Termination or Breach.

         (a) If this Agreement is validly terminated pursuant to Section 13.1,
there will be no liability or obligation on the part of the Sellers or the
Purchasers (or any of their Affiliates or any of its or their respective
officers, directors, employees, agents or other Representatives) except as
provided in Section 13.2(b) and except that the provisions with respect to
expenses in Section 14.3 and confidentiality in Section 14.5 will continue to
apply following any such termination.

         (b) Notwithstanding any other provision in this Agreement to the
contrary, if this Agreement is validly terminated by the Sellers pursuant to
Section 13.1(c) or by the Purchasers pursuant to Section 13.1(d) hereof as a
result of the willful breach by the non-terminating party, the terminating party
may recover such remedies, including damages and fees and expenses of attorneys
as may be available at law or equity.

                                   ARTICLE 14

         14.2 Entire Agreement. This Agreement supersedes all prior discussions
and agreements (including the Letter of Intent) between the parties with respect
to the subject matter hereof and contains the sole and entire agreement between
the parties hereto with respect to the subject matter hereof.

         14.3 Expenses. Except as otherwise expressly provided in this Agreement
(including as provided in Section 13.2), whether or not the transactions
contemplated hereby are consummated, each party will pay its own costs and
expenses incurred in connection with the negotiation, execution and closing of
this Agreement and the transactions contemplated hereby.

         14.4 Public Announcements. No press releases or similar public
announcements concerning this Agreement and the transactions contemplated hereby
will be issued by any party without the prior consent of the other parties,
except as such release or public announcement may be required by Law (including,
for the avoidance of doubt, rules and regulations of any stock exchange), in
which case the party required to make the release or public announcement will,
to the extent practicable, consult with the other parties regarding such release
or announcement in advance thereof.

         14.5 Confidentiality. Each party hereto will hold, and will use
commercially reasonable efforts to cause its Affiliates and their respective
Representatives to hold, in strict confidence from any Person (other than any
such Affiliate or Representative), unless (i) compelled to disclose by judicial
or administrative process (including in connection with obtaining the necessary
approvals of this Agreement and the transactions contemplated hereby of
Governmental or Regulatory Authorities) or by other requirements of Law
(including exchange rules) or (ii) disclosed in an action or proceeding brought
by a party hereto in pursuit of its rights or in the exercise of its remedies
hereunder, all documents and information concerning the other party or any of
its Affiliates furnished to it by the other party or such other party's
Representatives in connection with this Agreement or the transactions
contemplated hereby, except to the extent that such documents or information can
be shown to have been

                                       32

(a) previously known by the party receiving such documents or information, (b)
in the public domain (either prior to or after the furnishing of such documents
or information hereunder) through no fault of such receiving party or (c) later
acquired by the receiving party from another source if the receiving party is
not aware that such source is under an obligation to another party hereto to
keep such documents and information confidential. In the event the transactions
contemplated hereby are not consummated, upon the request of the other party,
each party hereto will, and will cause its Affiliates and their respective
Representatives to, promptly (and in no event later than five (5) Business Days
after such request) redeliver or cause to be redelivered all copies of
confidential documents and information furnished by the other party in
connection with this Agreement or the transactions contemplated hereby and
destroy or cause to be destroyed all notes, memoranda, summaries, analyses,
compilations and other writings related thereto or based thereon prepared by the
party furnished such documents and information or its Representatives. The
obligations contained in this Section 14.5 shall survive for two (2) years
following the termination or abandonment of this Agreement or the Closing, as
the case may be. The provisions of this Section 14.5 supersede any prior
Confidentiality Agreement between the parties pertaining to the subject matter
hereof.

         14.6 Waiver. Any term or condition of this Agreement may be waived at
any time by the party that is entitled to the benefit thereof, but no such
waiver shall be effective unless set forth in a written instrument duly executed
by or on behalf of the party waiving such term or condition. No waiver by any
party of any term or condition of this Agreement, in any one or more instances,
shall be deemed to be or construed as a waiver of the same or any other term or
condition of this Agreement on any future occasion. All remedies, either under
this Agreement or by Law or otherwise afforded, will be cumulative and not
alternative.

         14.7 Amendment. This Agreement may be amended, supplemented or modified
only by a written instrument duly executed by or on behalf of each party hereto.

         14.9 No Assignment; Binding Effect. Neither this Agreement nor any
right, interest or obligation hereunder may be assigned by any party hereto
without the prior written consent of the other party hereto and any attempt to
do so will be void, except for (a) assignments and transfers by operation of
Law, (b) assignments and transfers by the Purchasers of their rights, interests
or obligations hereunder, in whole or in part, to an Affiliate with the consent
of the Sellers, which shall not be unreasonably withheld or delayed, and (c)
that the Purchasers may assign any or all of their rights, interests and
obligations hereunder to any financial institution providing purchase money or
other financing to the Purchasers from time to time as collateral security for
such financing, but no such assignment referred to in clauses (b) or (c) shall
relieve the assigning party of its obligations hereunder. Subject to the
preceding sentence, this Agreement is binding upon, inures to the benefit of and
is enforceable by the parties hereto and their respective successors and
assigns.

         14.10 Headings. The headings used in this Agreement have been inserted
for convenience of reference only and do not define or limit the provisions
hereof.

         14.11 Invalid Provisions. If any provision of this Agreement is held to
be illegal, invalid or unenforceable under any present or future Law, and if the
rights or obligations of any party hereto under this Agreement will not be
materially and adversely affected thereby, (a) such provision will be fully
severable, (b) this Agreement will be construed and enforced as if such illegal,

reorganization, arrangement, moratorium or other similar Laws relating to or
affecting the rights of creditors generally, or by general equitable principles.

                  (c) No Conflicts. The execution and delivery by such Caithness
Seller of this Agreement does not and the performance by such Caithness Seller
of its obligations under this Agreement and the consummation of the transactions
contemplated hereby will not:

                     (i) conflict with or result in a violation or breach of any
of the terms, conditions or provisions of its certificate of formation and
limited liability company agreement, or any resolution adopted by the board of
directors of Caithness; or

                     (ii) assuming that the consents, approvals and waivers

acceleration) under any of the terms, conditions or provisions of any note,
bond, mortgage, indenture, license, agreement or other instrument or obligation
to which such Caithness Seller is a party or by which it or any of the Purchased
Interests owned by it may be bound, or result in the creation of a Lien on such
Purchased Interests; or

                     (iii) assuming that the Caithness Sellers' Consents have
been obtained, conflict with or result in a violation or breach of any term or
provision of any Law or Order applicable to it or any of its Assets and
Properties;

                  (d) Governmental Approvals; Filings. Except as set forth in

action of, filing with or notice to any Governmental or Regulatory Authority on
the part of such Caithness Seller or any Related Purchased Entity is required in
connection with the execution, delivery and performance of this Agreement or the
consummation of the transactions contemplated hereby.

                                       17

                  (e) Purchased Interests. Such Caithness Seller is the holder

                  (f) Legal Proceedings.

                     (i) Except as set forth in Section 3.2(f)(i) of the Sellers

the issuance of an Order restraining, enjoining or otherwise prohibiting or
making illegal, materially delaying or preventing the consummation of, or
awarding damages as a result of, any of the transactions contemplated by this
Agreement, or (B) individually or in the aggregate, to create a Related
Purchased Entity Material Adverse Effect; and

                     (ii) Except as set forth in Section 3.2(f)(ii) of the
Sellers Disclosure Schedule, to the Knowledge of such Caithness Seller, there
are no Orders issued since December 31, 2001 outstanding against such Seller or
any Related Purchased Entity which, individually or in the aggregate, could

                  (g) Brokers. All negotiations relative to this Agreement and
the transactions contemplated hereby have been carried out by such Caithness
Seller directly with the Purchasers without the intervention of any Person on

alleged, possible or potential obligation on the part of any Related Purchased
Entity to undertake, or to bear all or any portion of the cost of, any remedial
action of any nature, which could reasonably be expected to create or result in
a Material Adverse Effect upon its Related Purchased Entity.

                                       18

                  (j) Absence of Certain Changes. Since December 31, 2001, in
the case of Ormesa Geothermal and GEM Resources, and the date of the unaudited
financial statement for each of the other Related Purchased Entities set forth
in Section 3.1(j), as the case may be, except as disclosed in Section 3.2(j) of
the Sellers Disclosure Schedule, to the Knowledge of such Caithness Seller, no
Related Purchased Entity has:

                     (i) incurred, permitted or allowed any of its Assets and
Properties to be subjected to any Lien, other than Liens existing on the date
hereof or Permitted Liens;

                     (ii) incurred or created any indebtedness or obligation, or
assumed or guaranteed (whether by way of guarantee, endorsement, indemnity,

                     (iii) sold, transferred, leased, or otherwise disposed of
any Assets and Properties, except in the ordinary course of business consistent
with past practice;

                     (iv) incurred any material liabilities or obligations which
would be required by GAAP to be shown on its balance sheet or the footnotes
thereto;

                     (v) suffered any damage, destruction or casualty loss
(whether or not covered by insurance) in excess of $50,000.00;

                     (vi) entered into any transaction outside the ordinary
course of its business;

                     (vii) renegotiated, amended, waived in writing or
terminated (partially or completely) any Material Contract to which it is a
party, or any Environmental Permit or License related to the ownership and
operations of any Facility;

                     (viii) made any payment, loan or advance to, or entered
into any agreement, arrangement or transaction with, any of its Affiliates, or
any business or entity in which any of its partners or their Affiliates, or any
directors, officers members, managers or employees of any of the foregoing have
either a direct or indirect interest that will continue in effect beyond the
Closing other than in the ordinary course of the business of such Related
Purchased Entity;

                     (ix) changed its organizational documents;

                     (x) reached any understanding or entered into any Contract
or commitment (contingent or otherwise) to do or engage in, or which could

                  (k) Regulatory Status. On November 5, 1990 and May 11, 1989,
the GEM Facility and Ormesa I Facility, respectively, were each certified as a
QF. To the Knowledge of such Caithness Seller, neither it nor any Related
Purchased Entity have received any written notice from any Governmental or
Regulatory Authority of any claim, action, proceeding or investigation denying,
challenging or otherwise questioning the status of either Facility as a QF.

                                       19

                  (l) Real Property. To the Knowledge of such Caithness Seller,
such Caithness Seller has no reason to believe that the list of the geothermal
leases pursuant to which real property is leased by any Related Purchased Entity
and used or held for use in connection with its business set forth on Section
3.2(l) does not include all geothermal leases so used or held for use. Except as
set forth in Section 3.2(l) of the Sellers Disclosure Schedule, to the Knowledge
of such Caithness Seller, since December 31, 2001, no Related Purchased Entity
has been in material default under any of the leases listed thereon.

                  (m) Tangible Personal Property. To the Knowledge of such
Caithness Seller, such Caithness Seller has no reason to believe that the list
of Tangible Personal Property set forth in Section 3.1(n) of the Sellers
Disclosure Schedule does not include all Tangible Personal Property with a value
exceeding $10,000.00 that is included in, or used in the operation of, any
Facility.

                  (n) Material and other Contracts.

                     (i) Except as set forth in Section 3.2(n) of the Sellers
Disclosure Schedule, to the Knowledge of such Caithness Seller, neither it nor
any Related Purchased Entity have received written notice from any other party
to a Material Contract to the effect that any Related Purchased Entity is in
violation or breach of or default under any Material Contract to which such
Related Purchased Entity is a party (or with notice or lapse of time or both,
would be in violation or breach of or default under any such Material Contract).

                     (ii) To such Caithness Seller's Knowledge, Section 3.2(n)
of the Sellers Disclosure Schedule contains a list of all Contracts (excluding,
for the avoidance of doubt, Environmental Permits and other Licenses) with a
value or consideration in excess of $50,000.00 to which any Related Purchased
Entity, to such Caithness Seller's Knowledge, is a party, or has been a party
since December 31, 2001, and by which any Related Purchased Entity or any of its
assets may be bound or affected as of the Closing Date. To the Knowledge of such
Caithness Seller, no Contract (excluding, for the avoidance of doubt,
Environmental Permits and other Licenses) required to be set forth thereon has
been amended or assigned except as set forth in Section 3.2(n) of the Sellers
Disclosure Schedule. To the Knowledge of such Caithness Seller, no Related
Purchased Entity is a party to any series of related Contracts (excluding, for
the avoidance of doubt, Environmental Permits and other Licenses) in effect as
of the Closing Date that in the aggregate have a value or consideration in
excess of $150,000.00 which are not listed on Section 3.2(n) of the Sellers
Disclosure Schedule.

                  (o) Insurance. Except as set forth in Section 3.2(o) of the
Sellers Disclosure Schedule, to the Knowledge of such Caithness Seller, there
are no outstanding claims under or in respect of any insurance policy to which
any Related Purchased Entity is a party or which provides coverage to or for the
benefit of or with respect to any Related Purchased Entity or any Facility.

                  (p) Disclosure. The copies of written materials concerning any
Related Purchased Entity and the Facility operated by its Related Purchased
Entity that such Caithness Seller has made available for inspection and
reproduction by the Purchasers or their Representatives constitute accurate
copies of the originals thereof, and to the Knowledge of such

                                       20

Caithness Seller, the files and records that such Caithness Seller has made
available for inspection and reproduction by the Purchasers or their
Representatives constitute all documents (other than the Excluded Records) that
contain material factual information in the possession of such Caithness Seller
concerning its Related Purchased Entities and such Facility.

                                    ARTICLE 4
                REPRESENTATIONS AND WARRANTIES OF THE PURCHASERS

                  Each Purchaser severally, and not jointly and severally,
represents and warrants with respect only to itself, to the Sellers that as of
the date hereof:

                  4.1 Corporate Existence. Each Purchaser is a limited liability
company, duly organized, validly existing and in good standing under the Laws of
the State of Delaware.

                  4.2 Authority. The execution and delivery by each Purchaser of
this Agreement and the performance by each Purchaser of its obligations
hereunder have been duly and validly authorized by all necessary action on its
behalf. This Agreement has been duly and validly executed and delivered by each
Purchaser and constitutes the legal, valid and binding obligation of each
Purchaser enforceable against it in accordance with its terms except as the same
may be limited by bankruptcy, insolvency, reorganization, arrangement,
moratorium or other similar Laws relating to or affecting the rights of
creditors generally, or by general equitable principles.

                  4.3 No Conflicts. The execution and delivery by each Purchaser
of this Agreement, the performance by each Purchaser of its obligations
hereunder and the consummation of the transactions contemplated hereby will not:

                  (a) conflict with or result in a violation or breach of any of
the terms, conditions or provisions of the organizational documents of each
Purchaser or any resolution adopted by its board of directors;

                  (b) be in violation of or result in a default (or give rise to
any right of termination, cancellation or acceleration) under any of the terms,
conditions or provisions of any note, bond, mortgage, indenture, license,
agreement or other instrument or obligation to which each Purchaser is a party
or by which any of its respective Assets and Properties may be bound; or

                  (c) conflict with or result in a violation or breach of any
term or provision of any Law or Order applicable to each Purchaser or any of its
Assets and Properties.

                  4.4 Governmental Approvals and Filings. No consent, approval
or action of, filing with or notice to any Governmental or Regulatory Authority
on the part of each Purchaser is required in connection with the execution,
delivery and performance of this Agreement or the consummation of the
transactions contemplated hereby.

                  4.5 Legal Proceedings. There are no actions or proceedings
pending or, to the Knowledge of each Purchaser, threatened against it or any of
its Assets and Properties which could reasonably be expected to result in the
issuance of an Order restraining, enjoining or

                                       21

otherwise prohibiting or making illegal the consummation of any of the
transactions contemplated by this Agreement.

                  4.6 Brokers and Investment. All negotiations relative to this
Agreement and the transactions contemplated hereby have been carried out by each
Purchaser, or an Affiliate thereof, directly with the Sellers without the
intervention of any other Person on behalf of each Purchaser in such manner as
to give rise to any valid claim by any Person (including, for the avoidance of
doubt, any Affiliate of each Purchaser) against the Sellers for a finder's fee,
brokerage commission or similar payment.

                  4.7 Absence of Regulation. None of the Purchasers is subject
to regulation as an "electric utility company," "public utility company" or
"holding company" under the Public Utility Holding Company Act of 1935, as
amended. None of the Purchasers is an "investment company" or a company
"controlled" by an "investment company" within the meaning of the Investment
Company Act of 1940, as amended, or an "investment advisor" within the meaning
of the Investment Company Act of 1940, as amended.

                  4.8 Purchase for Investment. The Purchasers are acquiring the
Purchased Interests for investment for their own account, and not with a view to
resell or distribute any part thereof; neither Purchaser has a present intention
to sell, grant a participation in or otherwise distribute the Purchased
Interests; provided, however, that the right to dispose of the Purchased
Interests shall be entirely within the sole discretion of the Purchasers. The
Purchasers understand and acknowledge that the Purchased Interests have not been
registered under the Securities Act of 1933, as amended, or under any applicable
blue sky or state securities law, and agree that any sale by the Purchasers of
such interests may only be made in compliance therewith.

                  4.9 Financing. The Purchasers have sufficient cash and/or
access to sufficient cash through their Affiliates to make the payments required
under Section 2.2 of this Agreement.

                  4.10 Knowledgeable Purchasers. The Purchasers (i) are
represented by competent legal, tax and financial counsel in connection with the
negotiation, execution and delivery of this Agreement, (ii) together with their
Affiliates, have sufficient knowledge and experience in owning, managing and
operating power generating facilities to enable them to evaluate the Purchased
Entities, the Facilities and the business of the Purchased Entities, and the
technical, commercial, financial, legal, regulatory and other risks associated
with owning the Purchased Interests, and (iii) acknowledge that pursuant to this
Agreement they will have, prior to the date hereof, performed and requested all
due diligence that they have deemed necessary to perform in order to evaluate
and close the transactions contemplated hereby, and that in making the decision
to enter into this Agreement and to consummate the transactions contemplated
hereby and thereby, they have relied on their own independent investigation,
analysis and evaluation of the Purchased Entities, the Facilities, and the
assets, properties, business, financial condition and prospects of the Purchased
Entities and upon the express representations, warranties and covenants in this
Agreement and in any certificate delivered at the Closing.

                                       22

                                    ARTICLE 5
                            COVENANTS OF THE SELLERS

                  Each Seller severally, and not jointly and severally with any
other Seller, covenants and agrees with the Purchasers with respect to itself
and each Related Purchased Entity that, from the date hereof to the Closing Date
(or, with respect to the covenants and agreements contained in Section 5.3,
until fully performed), such Seller will comply with all covenants and
provisions of this Article 5, except to the extent the Purchasers may otherwise
consent in writing.

                  5.1 Access of the Purchasers. The Sellers will provide or
cause to be provided to the Purchasers and their Representatives, at their sole
cost and expense, reasonable access, upon reasonable prior notice and during
normal business hours, to the officers and agents of the Sellers and Purchased
Entities who have any responsibility for the Purchased Entities or any Facility,
and to the Sellers' and Purchased Entities' accountants, and shall provide the
Purchasers and their Representatives with access to the Facilities and the Books
and Records of the Purchased Entities (other than the Excluded Records);
provided that no investigation pursuant to this Section by the Purchasers will
affect, or limit liability for, any representation or warranty of the Sellers
contained in Article 3 and Article 5 of this Agreement.

                  5.2 Performance Until Closing. Until the Closing Date, the
Sellers shall be responsible for all amounts payable under the Contracts and for
the timely and full performance of all obligations of each Purchased Entity
thereunder, and the enforcement of all provisions thereof.

                  5.3 Certain Restrictions. Except as the Purchasers may
specifically authorize in writing, and except for those certain capital
expenditures that will be funded and undertaken by the Sellers prior to the
Closing pursuant to the terms and conditions of the Letter Agreement Concerning
Capital Expenditures, and except for any undertakings by the Sellers to satisfy
or settle the claims of MMS or BLM with respect to the Royalty Payment
Liabilities (as such terms are defined in the MMS Audit Letter), and except for
any undertaking by the Sellers to satisfy or settle the Disputed Payment (as
such term is defined in the IID Letter), the Sellers will cause the Purchased

Equity Interests in lieu of or in substitution for any of their Equity
Interests;

                  (b) issue, deliver, sell, pledge, dispose of or otherwise
subject to any Lien any of their Equity Interests, any other voting securities
or equity equivalent or any securities convertible into, or any rights, warrants
or options to acquire, any such Equity Interests, voting securities or
convertible securities or equity equivalent;

                                       23

                  (c) incur, permit or allow any Lien on any of their Assets and

                  (l) pay, discharge or satisfy any obligation or liability
other than the payment, discharge or satisfaction in the ordinary course of

other terms or provisions of this

                                       24

Agreement to the contrary, the Sellers shall be authorized and entitled to use
cash available to any of the Purchased Entities on or prior to the Closing
(including any cash presently held by any third party in a deposit account or
otherwise that will be released as of the Closing to any of the Purchased
Entities and that has not been included in the Estimated Adjustment Statement
for purposes of making the adjustment to the Purchase Price pursuant to Section

Sellers or any other holder of any Equity Interest in any of the Purchased
Entities prior to Closing; or (ii) to pay, discharge or satisfy any obligation

other than ESI Ormesa IE Resources LLC, each of which will be prepared from and
in accordance with the Books and Records of such Purchased Entity and, to the
Knowledge of each FPLE Seller, in conformity with GAAP.

                  5.5 Permits. The Sellers will use commercially reasonable
efforts to cause each Purchased Entity (a) to maintain in effect all its
existing Licenses and Environmental Permits and (b) to obtain any additional
Licenses and Environmental Permits not already issued, that are required in
connection with the normal course of business as conducted by such Purchased
Entity as of the date hereof.

                  5.6 Books and Records. On or before the Closing Date, the
Sellers will cause all Books and Records (other than the Excluded Records)
belonging or relating to a Purchased Entity that are required for the day-to-day
operations of the Purchased Entities to be in the possession of such Purchased
Entity, and the Sellers will make such Books and Records (other than the
Excluded Records) available to such Persons as the Purchasers shall instruct. No
later than thirty (30) days after the Closing Date, the Sellers will cause all
remaining Books and Records (other than the Excluded Records) belonging to or
relating to a Purchased Entity to be in the possession of such Purchased Entity
and the Sellers will make such Books and Records (other than the Excluded
Records) available to such Persons as the Purchasers shall instruct.

                  5.7 Operation in the Ordinary Course of Business. Except for
those certain capital expenditures that will be funded and undertaken by the
Sellers prior to the Closing pursuant to the terms and conditions of the Letter
Agreement Concerning Capital Expenditures, the Sellers will cause each Purchased
Entity to operate only in accordance with the Material Contracts, and any other
Contract (except to the extent failure to so operate would not result in a
Material Adverse Effect) to which it is a party, as set forth in Section 3.1(o)
of the Sellers Disclosure Schedule, and the Sellers will comply with all terms
of such Contracts with respect to the Facility and the Purchased Entity.

                  5.8 No Negotiations. Neither the Sellers nor any of their
affiliates, advisors or agents shall, directly or indirectly, initiate
discussions with, engage in negotiations with, or provide any information to any
corporation, partnership, person or other entity or group

                                       25

involving the possible sale, directly or indirectly, transfer or joint venture
of any Purchased Entity, its business or assets, or the Purchased Interests to
any person other than the Purchasers.

                  5.9 Notice. Each Seller will promptly notify the Purchasers of
the occurrence of any breach of any covenant of such Seller in this Article 5.

                                    ARTICLE 6
                           COVENANTS OF THE PURCHASERS

                  The Purchasers covenant and agree with the Sellers that they
will comply with all covenants and provisions of this Article 6, except to the
extent the Sellers may otherwise consent in writing.

                  6.1 Use of Certain Names. As soon as practicable, and in all
events within ninety (90) days after the Closing, the Purchasers shall cause
each Purchased Entity to eliminate any reference to the Sellers or their
Affiliates or any word or expression constituting an abbreviation of the
Sellers' or their Affiliates' names from the names under which such Purchased
Entity conducts business, and all of the foregoing words, expressions and
abbreviations shall be removed from the property, stationery and literature of
such Purchased Entity, and thereafter, the Purchasers and such Purchased Entity
shall not use any logos, trademarks or tradenames, belonging to the Sellers or
any Affiliate thereof.

                  6.2 Contract Security. Promptly, but in no event later than
ten (10) Business Days following the Closing, the Purchasers will, or will cause
the relevant Purchased Entity to, deliver substitute bonds, guarantees, letters
of credit or other security sufficient to cause the beneficiaries of the bonds,
guarantees, letters of credit or other security described on Exhibit IV hereto
to release their interest therein and, to the extent any funds are delivered to
the Purchasers or any Purchased Entity following any such release of any bonds,
guarantees, letters of credit or other security described on Exhibit IV hereto
following the Closing, the Purchasers will, or will cause such Purchased Entity
to, promptly pay such funds to the Sellers.

                  6.3 Books and Records. Upon prior written request from the
Sellers, the Purchasers shall use reasonable efforts to grant, and cause the
Purchased Entities to grant, the Sellers access during regular business hours to
such Books and Records that the Sellers may reasonably require in connection
with ongoing settlement negotiations with MMS or IID relating to matters
addressed in the MMS Audit Letter or the IID Letter, as the case may be, or in
connection with future matters addressed in the SCE Letter.

                                   TAX MATTERS

                  9.1 Representations, Warranties and Covenants. Each FPLE
Seller, severally and not jointly with any other Seller, represents, warrants
and covenants with respect to itself and any Related Purchased Entity that, and
each Caithness Seller, severally and not jointly with any other Seller, to such
Caithness Seller's Knowledge, represents, warrants and covenants with respect to
itself and any Related Purchased Entity that, as of the date of this Agreement
and, except as otherwise expressly provided, as of the Closing Date:

                                       28

                  (a) (i) Each Related Purchased Entity has filed when due all
Tax Returns that are required to be filed by it on or before the Closing Date;
(ii) such returns were prepared in the manner required by applicable Laws and
are true, correct, and complete in all material respects; and (iii) each Related
Purchased Entity has timely paid all Taxes imposed on or incurred by it as shown
on such Tax Returns as being owed. Neither the Sellers nor the Purchased
Entities have been notified of any claim or potential claim by any tax authority
for unpaid Taxes relating to events or periods before the Closing Date. No
waiver of any statute of limitations is in effect with respect to any Tax
Returns. Each Related Purchased Party is a partnership or disregarded as an
entity separate from its owner for federal and California state and local income
tax purposes and neither any Seller nor its Related Purchased Entity has taken a
position on any Tax Return that is inconsistent with this treatment. The
Facility Lease is a true lease for federal and California state and local income
tax purposes. There have not been any tax audits with respect to the Facility or
related transactions and no claims have been made by any Seller or its Related
Purchased Entity under any tax indemnities in the Facility Lease. As of the
Closing Date, no Purchased Entity will be a party to any Tax sharing or Tax
indemnity agreement, other than any tax indemnities in its favor in connection
with the Facility Lease and no Purchased Entity has, or will have as of the
Closing Date, any obligations or liabilities under any Tax sharing or Tax
indemnity arrangements previously in effect. The Sellers are not foreign persons
within the meaning of Section 1445 of the Code. All monies required to be
withheld by each Purchased Entity for income Taxes and social security and other
payroll Taxes have been collected or withheld with respect to employees, and
either paid to the respective taxing authorities or set aside in accounts for
such purpose.

                  (b) No "check-the-box" elections have been filed pursuant to
Treasury Regulations ss. 301.7701-3 for the Purchased Entities within the
60-month period ending on the Closing date.

                  (c) True and complete copies of all Tax Returns and all
schedules thereto filed by, or on behalf of, each Purchased Entity for all prior
taxable years have been (or will be upon request) made available to the
Purchasers for inspection.

                  9.2 Tax Matters.

                  (a) Transfer Taxes. The Sellers, on the one hand, and the
Purchasers, on the other, shall bear in equal portions and pay all sales, use,
transfer, recording, gains, stock transfer and other similar taxes and fees
("Transfer Taxes") if any, arising out of or in connection with the sale of the
Purchased Interests pursuant to this Agreement.

                  (b) Pre-Closing Taxes and Overlap Period Taxes. The Sellers
shall be responsible for all Pre-Closing Taxes and for Overlap Period Taxes to
the extent they relate to events or periods through 12:00 a.m. (California time)
on the Closing Date. Purchasers shall bear all supplemental or other state and
local real and personal property taxes which arise out of a change in ownership
of the Purchased Entities. The Sellers shall prepare and file, or cause to be
filed, Tax Returns for Pre-Closing Taxes. The Purchasers shall prepare and file
Tax Returns for Overlap Period Taxes, and will supply the Sellers with a draft
of any such returns and a written request for payment of the Sellers' share of
such Taxes. The Purchasers' preparation of any such Tax Returns shall be subject
to the Sellers' approval, which shall not be unreasonably

                                       29

withheld or delayed. Payments of the Sellers' share must be made to the
Purchasers by wire transfer within thirty (30) business days after such request.
Liability for Overlap Period Taxes will be allocated between the Sellers and the
Purchasers (i) in the case of Taxes based on gross receipts or income, on a
closing of the books method and (ii) in the case of Taxes not based on gross
receipts or income (e.g., property taxes) a fraction, the denominator of which
is the total number of days in the Tax period and the numerator of which for the
Seller is the number of days in the Tax period ending on the Closing Date and
for the Purchaser is the number of days in the Tax period after the Closing
Date. The parties agree to cooperate with one another with respect to preparing
and filing Tax Returns.

                  (c) Refunds. Any refund or credit of Pre-Closing Taxes or
Overlap Period Taxes paid by the Sellers shall be for the benefit of the
Sellers. The Purchasers shall pay any such refund to the Sellers within thirty
(30) days after the Purchasers or any Purchased Entity receive such refund or
actually realize the benefit of such credit.

                  (d) Contests. The Purchasers agree that, in the event the
Purchasers or any Purchased Entity receive notice in writing of any examination,
claim, settlement, proposed adjustment, administrative or judicial proceeding,
or other matter related to any Pre-Closing Taxes or Overlap Period Taxes for
which the Sellers may be liable under Section 9.2(b), the Purchasers will notify
the Sellers in writing promptly after receipt of such notice. The Purchasers
will be entitled to control any Tax contest, except to the extent that
responsibility for the disputed Tax liability falls solely on the Sellers, in
which case the Sellers will be entitled to control the Tax contest; provided,
however, that if responsibility for the disputed Tax liability falls solely on
the Sellers but the contest involves issues that may recur on a later Tax Return
of a Purchased Entity or the Purchasers with respect to a Purchased Entity, the
Sellers will not settle such Tax contest without the prior written consent of
the Purchasers, such consent not to be unreasonably withheld or delayed. The
Sellers shall notify the Purchasers in writing within thirty (30) business days
following receipt of the notice from the Purchasers described in this paragraph
9.2(d) that the Sellers assume control over the contest if so entitled. Each
party will bear its own expenses, and the controlling party will keep the other
party informed of developments in the case. The noncontrolling party or parties
shall have the opportunity to attend meetings with tax officials and to comment
on any written submissions before they are submitted. Suggestions by the
noncontrolling party or parties about the conduct of the contest will be
considered in good faith by the controlling party, but the controlling party
will make the ultimate decision on whether, how long and in what manner to
contest.

                  (e) Information. In connection with preparing any Tax Return
or preparing for any audit or other examination by any taxing authority or any
judicial or administrative proceedings relating to liability for Taxes, the
Sellers, the Purchasers and the Purchased Entities will provide information,
records or documents relating to Taxes as may be reasonably requested in writing
by another party to this Agreement or any Affiliate thereof. The Sellers will
not destroy any records related to any Purchased Entity for Tax periods
commencing before the Closing Date for a period of seven (7) years following the
date thereof without first giving notice to and obtaining the written consent of
the Purchasers (whose consent shall not be unreasonably withheld).

                                       30

                                   ARTICLE 10
                                    SURVIVAL

                  10.1 Survival of Representations, Warranties, Covenants and
Agreements. The representations, warranties, covenants and agreements of the
Sellers and the Purchasers contained in this Agreement (other than (i) the
covenants and agreements contained in Articles 10, 11 and 12, which covenants
and agreements shall survive in accordance with their terms, (ii) the covenants
and agreements in Section 14.5, which covenants and agreements shall survive for
a period of five (5) years after the Closing, (iii) the representations and
warranties contained in Sections 3.1(a), (b), (c), (e) and (g); 3.2(a), (b),
(c), (e) and (g); 4.1; 4.2; 4.3 and 4.6; which covenants, representations and
warranties shall survive indefinitely after the Closing, (iv) the covenants and
agreements contained in Article 9, which covenants and agreements shall survive
for the applicable statute of limitations, and (v) the representation contained
in Section 3.1(q) and 3.2(p), which shall not survive beyond the date hereof)
shall survive for a period of one (1) year after the Closing and thereafter
shall be time-barred; provided, however, that claims first asserted in writing
within the applicable period (whether or not the amount of any such claim has
become ascertainable within such period) shall not thereafter be time barred.

                  10.2 No Other Representations. Notwithstanding anything to the
contrary contained in this Agreement, each party agrees that the Sellers are
making no representation or warranty whatsoever, express or implied, except
those representations and warranties contained in Section 3.1 and 3.2 and in any
certificate delivered pursuant to Article 7. In particular, the Sellers make no
representation or warranty to the Purchasers with respect to (i) the operating
condition of the Facilities, the cost of operating the Facilities or the
revenues to be derived therefrom; (ii) the amount, quality or availability of
the geothermal resource, (iii) the creditworthiness of any counterparty to any
Contract or Material Contract, (iv) the accuracy of any forecast, study or
projection relating to the business or condition of any Purchased Entity; (v)
whether the Facilities can be financed; (vi) the ultimate feasibility or
economic worth of any Facility; or (vii) the effect on the business or condition
of any Purchased Entity of the sale of the Purchased Interests to the
Purchasers. With respect to any projection or forecast delivered by or on behalf
of the Sellers to the Purchasers, the Purchasers acknowledge that (i) there are
uncertainties inherent in attempting to make such projections, studies and
forecasts, (ii) they are familiar with such uncertainties and (iii) they are
taking full responsibility for making their own evaluation of the adequacy and
accuracy of all such projections, studies and forecasts furnished to them.

                                   ARTICLE 11
                                 INDEMNIFICATION

                  11.1 Indemnification. (a) The FPLE Sellers shall, jointly and
severally as to all FPLE Sellers only, to the fullest extent permitted by Law,
indemnify, defend and hold harmless, the Purchasers and their Affiliates and the
respective officers, directors, employees and shareholders of the foregoing, and
their successors and assigns (the "Purchasers Indemnified Parties") from,
against and with respect to any claim, liability, obligation or Loss, of any
kind or character, suffered, incurred or sustained by the Purchasers or any of
the foregoing or to which it or they become subject, arising out of or in any
manner incident, relating or attributable to:

                                       31

                     (i) any inaccuracy in any representation or breach of
warranty of any FPLE Seller contained in this Agreement or in any certificate,
instrument of transfer or other document or agreement executed by any FPLE
Seller in connection with this Agreement; and

                     (ii) any failure by any FPLE Seller to perform or observe,
or to have performed or observed, in full, any covenant, agreement or condition
to be performed or observed by any FPLE Seller under this Agreement or under any
certificates or other documents or agreements executed by any FPLE Seller in
connection with this Agreement. Under no circumstances shall the indemnification
obligation of the FPLE Sellers under this Article 11.1(a) extend to any Loss,
claim or liability suffered, incurred or sustained by the Purchasers as a result
of any event defined in Article 11.1(b)(i) or (ii).

                  (b) The Caithness Sellers shall, jointly and severally as to
all Caithness Sellers only, to the fullest extent permitted by Law, indemnify,
defend and hold harmless, the Purchasers Indemnified Parties from, against and
with respect to any claim, liability, obligation or Loss, of any kind or
character, suffered, incurred or sustained by the Purchasers or any of the
foregoing or to which it or they become subject, arising out of or in any manner
incident, relating or attributable to:

observe, or to have performed or observed, in full, any covenant, agreement or
condition to be performed or observed by any Caithness Seller under this
Agreement or under any certificates or other documents or agreements executed by
any Caithness Seller in connection with this Agreement. Under no circumstances
shall the indemnification obligation of the Caithness Sellers under this Article
11.1(b) extend to any Loss, claim or liability suffered, incurred or sustained
by the Purchasers as a result of any event defined in Article 11.1(a)(i) or
(ii).

                  (c) The Purchasers shall, to the fullest extent permitted by
Law, jointly and severally, indemnify, defend and hold harmless the Sellers and
their Affiliates and the respective partners, officers, directors, employees and
shareholders of the foregoing, and their successors and assigns (the "Sellers
Indemnified Parties") from, against and with respect to any claim, liability,
obligation judgment or Loss, of any kind or character, suffered, incurred or
sustained by the Sellers or any of the foregoing or to which they become
subject, arising out of or in any manner incident, relating or attributable to:

                     (i) any inaccuracy in any representation or breach of
warranty of the Purchasers contained in this Agreement or in any certificate,

to be performed or observed by it under this Agreement or under any certificates
or other documents or agreements executed by the Purchasers in connection with
this Agreement; and

                                       32

                     (iii) any events, occurrences or conditions relating to the
Purchased Entities, the Facilities, the Assets and Properties of any Purchased
Entities or the Contracts of the Purchased Entities in respect of all periods
after the Closing.

                  (d) Notwithstanding anything herein to the contrary, no
indemnification shall be available to the Purchasers Indemnified Parties under
Section 11.1 (a) or 11.1(b) hereof or to the Sellers Indemnified Parties under
Section 11.1(c) hereof:

                     (i) unless, with respect to any individual claim, the Loss
involves an amount in excess of $25,000.00; and

                     (ii) unless the aggregate amount of the Loss that would
otherwise be subject to indemnification with respect to such claim and all prior
claims exceeds $500,000.00 (such amount, the "Threshold Amount"), in which case
the party(ies) entitled to such indemnification shall be entitled to receive all
amounts of Loss in excess of the Threshold Amount.

                     (e) Notwithstanding anything herein to the contrary, no
Seller shall have any obligation to indemnify any Purchaser Indemnified Party
for any Loss pursuant to Section 11.1(a) or 11.1(b) hereof, and no Purchaser
shall have any obligation to indemnify any Seller Indemnified Party for any Loss
pursuant to Section 11.1(c) hereof, in each case to the extent such Loss arises
from the willful misconduct or gross negligence of any Purchaser or any Seller
or its Representatives, as applicable.

                  (f) Notwithstanding anything herein to the contrary, the
maximum aggregate liability of the FPLE Sellers to the Purchasers Indemnified
Parties under this Agreement for any and all Losses incurred by the Purchasers
Indemnified Parties for which indemnification is available pursuant to this
Agreement shall not exceed an amount equal to one million twenty-six thousand
one hundred Dollars ($1,026,100.00); provided that (i) the limitation contained
in this clause shall not apply to any Loss arising from a breach of the
representations in Sections 3.1(a), 3.1(b), and 3.1(e), and (ii) if the claim is
for Losses based upon an inaccuracy of the representation set forth in Section
3.1(j) and, as a result of the Claim the aggregate liability of the FPLE Sellers
would exceed the amount set forth above in this Section 11.1(f), the maximum
aggregate liability of the FPLE Sellers under this Section 11.1(f) shall be
increased to such amount as is necessary to satisfy such claim up to an
additional one million twenty-six thousand one hundred Dollars ($1,026,100.00).

                  (g) Notwithstanding anything herein to the contrary, the
maximum aggregate liability of the Caithness Sellers to the Purchasers
Indemnified Parties under this Agreement shall not exceed an amount equal to one
million twenty-six thousand one hundred Dollars ($1,026,100.00); provided that
the limitation contained in this clause shall not apply to any Loss arising from
a breach of the representations in Sections 3.2(a), 3.2(b), and 3.2(e).

                  11.2 Method of Asserting Claims. All claims for
indemnification by any Indemnified Party under this Section 11.2 will be
asserted and resolved as follows:

                  (a) In the event any claim or demand in respect of which an
Indemnified Party might seek indemnity under Section 11.1 is asserted against or
sought to be collected from such

                                       33

Indemnified Party by a Person other than the Sellers, the Purchasers or any
Affiliate of the Sellers or the Purchasers (a "Third Party Claim"), the
Indemnified Party shall deliver a Claim Notice with reasonable promptness to the
Indemnifying Party.

                  (i) If the Indemnifying Party notifies the Indemnified Party
within the Dispute Period that the Indemnifying Party desires to defend the
Indemnified Party with respect to the Third Party Claim pursuant to this Section
11.2(a), and such Indemnifying Party confirms its liability with respect
thereto, then the Indemnifying Party will have the right to defend, at the sole
cost and expense of the Indemnifying Party, such Third Party Claim by all
appropriate proceedings, which proceedings will be vigorously and diligently
prosecuted by the Indemnifying Party, with counsel reasonably acceptable to the
Indemnified Party, to a final conclusion or will be settled at the discretion of
the Indemnifying Party (subject to the limitations set forth below). From and
after the Indemnifying Party's delivery of the notice referred to in the first
sentence of this Section 11.2(a)(i), the Indemnifying Party will have full
control of such defense and proceedings, including any settlement thereof;
provided, that the Indemnifying Party may not settle or compromise any Third
Party Claim in any manner that results in any continuing liability or obligation
for the Indemnified Party or any admission of liability or wrongdoing by the
Indemnified Party, without, in any such case, the prior written consent of the
Indemnified Party, which will not be unreasonably withheld. If requested by the
Indemnifying Party, the Indemnified Party will, at the sole cost and expense of
the Indemnifying Party, cooperate with the Indemnifying Party and its counsel in
contesting any Third Party Claim that the Indemnifying Party elects to contest,
or, if appropriate and related to the Third Party Claim in question, in making
any counterclaim against the Person asserting the Third Party Claim, or any
cross-complaint against any Person (other than the Indemnified Party or any of
its Affiliates). Notwithstanding the foregoing, the Indemnified Party may take
over the control of the defense or settlement of a Third Party Claim at any time
if it irrevocably waives its right to indemnity under Section 11.1 with respect
to such Third Party Claim. Should the Indemnifying Party have interests that
diverge materially from those of the Indemnified Party, the Indemnified Party
shall have the right to request separate counsel from that representing the
Indemnifying Party, the expenses of such separate representation to be paid by
the Indemnifying Party.

                  (ii) If the Indemnifying Party fails to notify the Indemnified
Party within the Dispute Period that the Indemnifying Party desires to defend
the Third Party Claim pursuant to Section 11.2(a), or if the Indemnifying Party
gives such notice but fails to prosecute vigorously and diligently or settle the
Third Party Claim, then the Indemnified Party will have the right to defend, at
the sole cost and expense of the Indemnifying Party, the Third Party Claim by
all appropriate proceedings, which proceedings will be vigorously and diligently
prosecuted by the Indemnified Party to a final conclusion or will be settled at
the discretion of the Indemnified Party (with the consent of the Indemnifying
Party, which consent will not be unreasonably withheld). The Indemnified Party
will have full control of such defense and proceedings, including (except as
provided in the immediately preceding sentence) any settlement thereof;
provided, that if requested by the Indemnified Party, the Indemnifying Party
will, at the sole cost and expense of the Indemnifying Party, cooperate with the
Indemnified Party and its counsel in contesting any Third Party Claim which the
Indemnified Party is contesting, or, if appropriate and related to the Third
Party Claim in question, in making any counterclaim against the Person asserting
the Third Party Claim, or any cross-complaint against any Person (other than the
Indemnified Party or any of its Affiliates).

                                       34

                  (iii) If the Indemnifying Party notifies the Indemnified Party
that it does not dispute its liability to the Indemnified Party with respect to
the Third Party Claim under Section 11.1 or fails to notify the Indemnified
Party within the Dispute Period whether the Indemnifying Party disputes its
liability to the Indemnified Party with respect to such Third Party Claim, the
Loss arising from such Third Party Claim will be conclusively deemed a liability
subject to the limits of the Indemnifying Party under Section 11.1 and the
Indemnifying Party shall pay the amount of such Loss to the Indemnified Party on
demand following the final determination thereof. If the Indemnifying Party has
timely disputed its liability with respect to such claim, the Indemnifying Party
and the Indemnified Party will proceed in good faith to negotiate a resolution
of such dispute, and if not resolved through negotiations within the Resolution
Period, the Indemnified Party shall be entitled to seek such remedies against
the Indemnifying Party as may then be available to it under this Agreement and
applicable Laws.

                  (b) In the event any Indemnified Party should have a claim
under Section 11.1 against any Indemnifying Party that does not involve a Third
Party Claim, the Indemnified Party shall deliver an "Indemnity Notice" with
reasonable promptness to the Indemnifying Party. If the Indemnifying Party
notifies the Indemnified Party that it does not dispute the claim or the amount
of Loss therefrom described in such Indemnity Notice or fails to notify the
Indemnified Party within the Dispute Period that it disputes the claim described
in the Indemnity Notice, the Loss in the amount specified in the Indemnity
Notice will be conclusively deemed a liability of the Indemnifying Party under
Section 11.1, subject to the limits set forth in Sections 11.1(d) and 11.1(e)
hereof, and the Indemnifying Party shall pay the amount of such Loss to the
Indemnified Party on demand. If the Indemnifying Party has disputed its
liability with or the amount of the Loss therefrom respect to such claim, such
dispute shall be resolved in accordance with the provisions of Article 12
hereof.

                  11.3 Exclusivity. After the Closing, to the extent permitted
by applicable Laws, and except in the case of fraud, gross negligence or willful
misconduct, the indemnities set forth in this Article 11 shall be the exclusive
remedies of the Purchasers and the Sellers and their respective officers,
directors, employees, agents and Affiliates due to misrepresentation, breach of
warranty, nonfulfillment or failure to be performed of any covenant or agreement
contained in this Agreement or any events, occurrences or conditions relating to
the Facilities in respect of all periods on or after the date hereof for the
Sellers, and the parties shall not be entitled to a rescission of this Agreement
or to any further indemnification rights or claims of any nature whatsoever in
respect thereof, all of which the parties hereto hereby waive; provided,
however, that the foregoing provision shall not limit or restrict the
availability of specific performance or other injunctive or equitable relief
(other than rescission) to the extent that specific performance or such other
relief would otherwise be available to a party under this Agreement.

                  11.4 Tax Treatment of Indemnification. The Seller and the
Purchasers agree to treat (and shall cause each of their respective affiliates
to treat) any indemnity payment under this Agreement as an adjustment to the
Purchase Price unless a final determination (which shall include execution of an
IRS Form 870-AD or successor form) provides otherwise.

                                       35

                                   ARTICLE 12
                               DISPUTE RESOLUTION

                  In the event an action, dispute, claim, counterclaim or
controversy ("Dispute") arises between the parties arising out of or relating to
this Agreement, the aggrieved party shall promptly notify the other party of the
Dispute within ten (10) Business Days after such Dispute arises. If the parties
have failed to resolve the Dispute within ten Business Days after delivery of
such notice, each party shall, within five (5) Business Days thereafter,
nominate a senior officer of its management to meet to attempt to resolve the
Dispute. The senior officers shall meet within twenty (20) Business Days after
their nomination. If the matter has not been resolved within fourteen (14) days
after the meeting of the senior executives, either party may pursue any and all
available legal remedies, unless the parties mutually agree to an alternative
dispute resolution procedure.

                                   ARTICLE 13
                                  EFFECTIVENESS

                                  MISCELLANEOUS

14.1 Notices. Unless this Agreement specifically requires otherwise, any notice,

                  14.2 Entire Agreement. This Agreement supersedes all prior
discussions and agreements (including the Letter of Intent) between the parties
with respect to the subject matter hereof and contains the sole and entire
agreement between the parties hereto with respect to the subject matter hereof.

                  14.3 Expenses. Except as otherwise expressly provided in this
Agreement (including as provided in Section 13.2), whether or not the
transactions contemplated hereby are consummated, each party will pay its own
costs and expenses incurred in connection with the negotiation, execution and
closing of this Agreement and the transactions contemplated hereby.

                  14.4 Public Announcements. No press releases or similar public
announcements concerning this Agreement and the transactions contemplated hereby
will be issued by any party without the prior consent of the other parties,
except as such release or public announcement may be required by Law (including,
for the avoidance of doubt, rules and regulations of any stock exchange), in
which case the party required to make the release or public announcement will,
to the extent practicable, consult with the other parties regarding such release
or announcement in advance thereof.

                  14.5 Confidentiality. Each party hereto will hold, and will
use commercially reasonable efforts to cause its Affiliates and their respective
Representatives to hold, in strict confidence from any Person (other than any
such Affiliate or Representative), unless (i) compelled to disclose by judicial
or administrative process (including in connection with obtaining the necessary
approvals of this Agreement and the transactions contemplated hereby of
Governmental or Regulatory Authorities) or by other requirements of Law
(including exchange rules) or (ii) disclosed in an action or proceeding brought
by a party hereto in pursuit of its rights or in the exercise of its remedies
hereunder, all documents and information concerning the other party or any of
its Affiliates furnished to it by the other party or such other party's

                                       38

Representatives in connection with this Agreement or the transactions
contemplated hereby, except to the extent that such documents or information can
be shown to have been (a) previously known by the party receiving such documents
or information, (b) in the public domain (either prior to or after the
furnishing of such documents or information hereunder) through no fault of such
receiving party or (c) later acquired by the receiving party from another source
if the receiving party is not aware that such source is under an obligation to
another party hereto to keep such documents and information confidential. In the
event the transactions contemplated hereby are not consummated, upon the request
of the other party, each party hereto shall, and shall cause its Affiliates and
their respective Representatives to, promptly (and in no event later than five
(5) Business Days after such request) redeliver or cause to be redelivered all
copies of confidential documents and information furnished by the other party in
connection with this Agreement or the transactions contemplated hereby and
destroy or cause to be destroyed all notes, memoranda, summaries, analyses,
compilations and other writings related thereto or based thereon prepared by the
party furnished such documents and information or its Representatives. The
obligations contained in this Section 14.5 shall survive for two (2) years
following the termination or abandonment of this Agreement or the Closing, as
the case may be. The provisions of this Section 14.5 supersede that certain
Confidentiality Agreement dated as of August 1, 2000, between Ormat Nevada Inc.
and FPLE in its entirety.

                  14.6 Waiver. Any term or condition of this Agreement may be
waived at any time by the party that is entitled to the benefit thereof, but no
such waiver shall be effective unless set forth in a written instrument duly
executed by or on behalf of the party waiving such term or condition. No waiver
by any party of any term or condition of this Agreement, in any one or more
instances, shall be deemed to be or construed as a waiver of the same or any
other term or condition of this Agreement on any future occasion. All remedies,
either under this Agreement or by Law or otherwise afforded, will be cumulative
and not alternative.

                  14.7 Amendment. This Agreement may be amended, supplemented or
modified only by a written instrument duly executed by or on behalf of each
party hereto.

                  14.8 No Third Party Beneficiary. The terms and provisions of
this Agreement are intended solely for the benefit of each party hereto and
their respective successors or permitted assigns, and it is not the intention of
the parties to confer third-party beneficiary rights upon any other Person
except for such shareholders, officers, directors, employees, and Affiliates
referenced in Section 11.1.

                  14.9 No Assignment; Binding Effect. Neither this Agreement nor
any right, interest or obligation hereunder may be assigned by any party hereto
without the prior written consent of the other party hereto and any attempt to
do so will be void, except for (a) assignments and transfers by operation of
Law, (b) assignments and transfers by the Purchasers of their rights, interests
or obligations hereunder, in whole or in part, to an Affiliate with the consent
of FPLE and Caithness, which shall not be unreasonably withheld or delayed, and
(c) that the Purchasers may assign any or all of their rights, interests and
obligations hereunder to any financial institution providing purchase money or
other financing to the Purchasers from time to time as collateral security for
such financing, but no such assignment referred to in clauses (b) or (c) shall
relieve the assigning party of its obligations hereunder. Subject to the

                                       39

preceding sentence, this Agreement is binding upon, inures to the benefit of and
is enforceable by each party hereto and its respective successors and assigns.

                  14.10 Headings. The headings used in this Agreement have been
inserted for convenience of reference only and do not define or limit the
provisions hereof.

                  14.11 Invalid Provisions. If any provision of this Agreement
is held to be illegal, invalid or unenforceable under any present or future Law,
and if the rights or obligations of any party hereto under this Agreement will
not be materially and adversely affected thereby, (a) such provision will be
fully severable, (b) this Agreement will be construed and enforced as if such
illegal, invalid or unenforceable provision had never comprised a part hereof,
(c) the remaining provisions of this Agreement will remain in full force and
effect and will not be affected by the illegal, invalid or unenforceable
provision or by its severance herefrom and (d) in lieu of such illegal, invalid
or unenforceable provision, there will be added automatically as a part of this
Agreement a legal, valid and enforceable provision as similar in terms to such
illegal, invalid or unenforceable provision as may be possible.

                  14.12 Governing Law. This Agreement shall be governed by and
construed in accordance with the Laws of the State of New York applicable to a
contract executed and performed in such State, without giving effect to the
conflicts of laws principles thereof other than Section 5-1401 and Section
5-1402 of the General Obligations Law of the State of New York.

                  14.13 Jurisdiction and Venue. Each of the parties hereto
hereby irrevocably and unconditionally consents and agrees that any actions,
suits or proceedings arising out of or relating to this Agreement and the

non-exclusive jurisdiction of the aforesaid courts, (ii) irrevocably agrees to
be bound by any final judgment (after any and all appeals) of any such court
with respect to such documents, (iii) irrevocably waives, to the fullest extent
permitted by law, any objection which it may now or hereafter have to the laying
of venue of any suit, action or proceedings with respect to such documents
brought in any such court, and further irrevocably waives, to the fullest extent
permitted by law, any claim that any such action, or proceeding brought in any
such court has been brought in any inconvenient forum, (iv) agrees that service
of any process, summons, notice or document in any such action may be effected
by mailing a copy thereof by U.S. registered or certified mail, postage prepaid,
to such party at its address set forth in Section 14.5, or at such other address
of which the other parties hereto shall have been notified will be effective
service for any action, suit or proceeding brought against it in any such court
and (v) agrees that nothing herein shall affect the right to effect service of
process in any other manner permitted by law or limit the right to bring any
suit, action or proceeding in any other jurisdiction.

                  14.14 Waiver of Trial by Jury. EACH OF THE PARTIES HERETO
HEREBY KNOWINGLY, VOLUNTARILY AND INTENTIONALLY WAIVE THE RIGHT ANY OF THEM MAY
HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION BASED

                                       40

HEREON, OR ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS AGREEMENT AND ANY
AGREEMENT CONTEMPLATED TO BE EXECUTED IN CONJUNCTION HEREWITH, OR ANY COURSE OF
CONDUCT, COURSE OF DEALING, STATEMENTS (WHETHER VERBAL OR WRITTEN) OR ACTIONS OF
ANY PARTY HERETO. THIS PROVISION IS A MATERIAL INDUCEMENT FOR THE PARTIES
ENTERING INTO THIS AGREEMENT.

                  14.15 Attorneys' Fees. In the event of any suit or other
proceeding between the parties with respect to any of the transactions
contemplated hereby or subject matter hereof, the prevailing party shall, in
addition to such other relief as the court or arbitrator may award, be entitled
to recover reasonable attorneys' fees and costs (including at the trial and
appellate levels) and expenses of investigation.

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

                  14.17 Waiver of Consequential Damages. NOTWITHSTANDING ANY
PROVISION IN THIS AGREEMENT TO THE CONTRARY, IN NO EVENT SHALL ANY PARTY OR ITS
AFFILIATES, OR ITS RESPECTIVE PARTNERS, OFFICERS, DIRECTORS, EMPLOYEES OR
REPRESENTATIVES, BE LIABLE HEREUNDER AT ANY TIME FOR PUNITIVE, CONSEQUENTIAL,
SPECIAL OR INDIRECT LOSS OR DAMAGE OF ANY OTHER PARTY OR ANY OF SUCH PARTY'S
AFFILIATES, INCLUDING LOSS OF PROFIT, LOSS OF REVENUE OR ANY OTHER SPECIAL OR
INCIDENTAL DAMAGES, WHETHER IN CONTRACT, TORT (INCLUDING NEGLIGENCE), STRICT
LIABILITY OR OTHERWISE, AND EACH PARTY HEREBY EXPRESSLY RELEASES THE OTHER
PARTIES, THEIR AFFILIATES AND THEIR RESPECTIVE OFFICERS, DIRECTORS, EMPLOYEES
AND REPRESENTATIVES THEREFROM.

                  14.18 Interest on Past Due Payments. If a payment is due to be
made by a party pursuant to this Agreement and such payment is not made within
thirty (30) days following receipt by such party of written demand for such
payment from the party entitled to receive such payment, then the party
obligated to make such payment agrees to pay interest on the amount due and
unpaid at a variable rate equal to the Prime Rate then in effect. Such interest
shall begin to accrue on the first day following the end of such thirty (30) day
period and shall continue to accrue on the unpaid amount until the past due
amount has been paid in full.

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

                  14.20 Further Assurances. The Sellers and the Purchasers each
agree, upon the request of the other party from time to time before and after
the Closing Date, to do, execute, acknowledge and deliver such other acts,
consents, instruments, documents and other assurances as may be reasonably
necessary to carry out and perform the transactions contemplated by this
Agreement.

of the close of business on the day prior to the date hereof (the "Adjustment
Date"): (i) a good faith estimate of the accrued liabilities of each Purchased
Entity that will remain unpaid following the Adjustment Date ("Liabilities"),
excluding any and all liabilities under the Financing Documents other than (x)
accrued and unpaid interest on the indebtedness of Ormesa Geothermal IH Trust
issued and outstanding pursuant to the Financing Documents to the date hereof
and (y) aggregate fees owed under the Financing Documents outstanding on the
date hereof, excluding any fees owed in connection with the unwinding of the
financing structure; (ii) a good faith estimate of the accrued gross revenues of
each Purchased Entity that will not have been received prior to the Adjustment
Date ("Accounts Receivable"); (iii) the expenses of each Purchased Entity that
have been paid in advance (including property taxes) as prorated for the period
following the Adjustment Date ("Prepaid Expenses"); and (iv) a good faith
estimate of the aggregate sum of the Interim Capital Expenditures as authorized
by the Purchasers in the Letter Agreement Concerning Capital Expenditures that
will have been made to and including the Adjustment Date, plus interest accrued
on such Interim Capital Expenditures from the date made until the Closing Date
at a variable rate equal to the Prime Rate from time to time in effect
(collectively, the "Capital Expenditures Amount"). The Estimated Adjustment
Statement will be prepared in conformity with GAAP, applied on a basis
consistent with the financial statements delivered to the Purchasers under
Section 3.1(j) of the Agreement. For the avoidance of doubt, Liabilities shall
not include any liabilities of any Purchased Entity to any Seller or any
Affiliate of a Seller that will be released or otherwise satisfied at or prior
to the date hereof.

         (b) If the Liabilities as set forth on the Estimated Adjustment
Statement for all of the Purchased Entities in the aggregate exceed the sum of
the Sellers' Credits (as defined below), the amount paid by the Purchasers under
Section 2.2 of the Agreement will be reduced (pro-rata to each Seller) by an
amount equal to the excess. If the Sellers' Credits exceed the Liabilities for
all of the Purchased Entities in the aggregate as set forth thereon, the amount
paid by the Purchasers under Section 2.2 of the Agreement will be increased
(pro-rata to each Seller) by an amount equal to the excess. For purposes hereof,
the "Sellers' Credits" mean all Accounts Receivable, plus the Prepaid Expenses,
plus the Capital Expenditures Amount, in each case for all of the Purchased
Entities in the aggregate as set forth on the Estimated Adjustment Statement.

         (c) Notwithstanding anything in this Schedule IV to the contrary, the
Parties agree that, for purposes of making the adjustments contemplated by this
Schedule IV, (1) Intercompany Obligations shall not be included in either
Liabilities or Accounts Receivable; (2) Liabilities that have been assumed by
the Sellers or any of them pursuant to the MMS Audit Letter, and any related
credits in favor of any of the Ormesa Entities described in such MMS Audit
Letter that will inure to the benefit of the Sellers, shall be governed by the
MMS Audit Letter and shall not be included in Liabilities or the Sellers'
Credits; (3) Liabilities that have been assumed by the Sellers or any of them
pursuant to the IID Letter, and any related credits in favor

                                       43

of any of the Ormesa Entities described in such IID Letter that will inure to
the benefit of the Sellers, shall be governed by the IID Letter and shall not be
included in Liabilities or the Sellers' Credits; (4) the maximum amount of
Liabilities payable to New Albion Resources Company included in the adjustments
shall be $150,000; and (5) $100,000 will be included in Liabilities on account
of plug and abandon expenses for Well Number 18-28, irrespective of whether such
liability is accrued or reflected on the financial statements.

(2)                           Adjustment Statement.
                              ---------------------

         (a) Within forty-five (45) days following the Closing Date, the
Purchasers shall prepare and deliver to the Sellers a final statement (the
"Final Adjustment Statement") that sets forth the same information as included
in the Estimated Adjustment Statement provided pursuant to Section 1(a) above,
adjusted to take into account the final figures as of 11:59 p.m. on the Closing
Date determined in accordance with the standard set forth in said Section 1(a).
The Sellers shall provide copies of all invoices or other billing information
actually received or sent by the Sellers during this 45 days period to allow the
Purchasers to prepare the Final Adjustment Statement in accordance with this
Section. The Final Adjustment Statement shall be accompanied by such backup
information and schedules as is reasonably required in order for the Sellers to
understand the computation of the amount(s) set forth therein.

         (b) The Parties shall attempt to agree upon the Final Adjustment
Statement within thirty (30) days following the delivery thereof to the Sellers.
If the Sellers dispute any item set forth on the Final Adjustment Statement, the
Sellers shall give the Purchasers written notice thereof within thirty (30) days
following the delivery to the Sellers of the Final Adjustment Statement, setting
forth in reasonable detail the disputed item or items. If the Sellers have not
delivered such notice to the Purchasers within such thirty (30) day period, the
Final Adjustment Statement shall be deemed to be final and, to the extent the
Final Adjustment Statement reflects an adjustment to the amounts paid by the
Purchasers under Section 2.2(a) of the Agreement that is different from the
adjustment made on the Closing Date, the party that benefited from the variance
in the adjustment made on the Closing Date shall pay to the other party the
variance amount within five (5) days following the expiration of such thirty
(30) day period. If the Sellers have delivered a notice of a dispute to the
Purchasers, the undisputed portion of the variance amount, if any, shall be paid
to the party entitled to receive the same within five (5) days following the
delivery of the notice by the Sellers to the Purchasers and the parties shall
jointly engage PricewaterhouseCoopers (or, if such firm is unable or unwilling
to act in such capacity, such other Big-5 accounting firm, excluding Arthur
Andersen, as may be agreed by the parties) (hereinafter, the "Auditors") and
shall direct the Auditors to make a final, binding determination of all such
disputes within forty-five (45) days of presentation to the Auditors by the
parties of the information that each such party believes supports its position
with respect to each disputed item. Such information shall be presented by each
party to the Auditors within ten (10) days following the selection thereof. The
parties will further direct the Auditors to deliver a written notice to the
Purchasers and the Sellers setting forth its determination with respect to each
disputed item. The results of such determination will be final and binding, and
the balance of the variance amount, if any, resulting from such determination
will be paid to the party entitled to receive the same within ten (10) days of
the independent accountant's notice of its determination. The parties agree that
the fees and expenses of the Auditors shall be borne in equal parts by the
Purchasers on the one hand, and the Sellers, on the other, and further agree
that in connection

                                        2

with the engagement of the Auditors, each of the Purchasers
and the Sellers will, if requested by the Auditors, execute a reasonable
engagement letter including customary indemnities.
