terminate with respect to the Heber Debtors and the DIP Lenders shall release

Geothermal Sale (whether from the Purchase Agreement or from an Alternative
Transaction) that Covanta, any of the other Debtors or non-Debtor subsidiaries
receive or have an interest in upon Closing of such sale or from time to time
thereafter shall be subject to (x) the valid, perfected non-voidable first
priority, senior priming liens of the DIP Agents, for the sole and exclusive
benefit of the DIP Lenders (such liens not being junior or subject to any other

DIP Lenders or the DIP Agents to not vote in favor of (or consent to) the
Reorganization Plan or object to any provision thereof, all of which rights are
hereby preserved.

                                  ARTICLE III

                  CLASSIFICATION OF CLAIMS AND EQUITY INTERESTS

         3.1 General Rules of Classification. This Heber Reorganization Plan
constitutes a joint reorganization plan of the Heber Debtors. In accordance with
section 1123(a)(1) of the Bankruptcy Code, Administrative Expense Claims and
Priority Tax Claims, as described in Article II, have not been classified and
thus are excluded from the Classes described below. The classification of Claims
and Equity Interests and implementation of the settlements set forth below shall
be applicable for all purposes, including voting, confirmation, and distribution
pursuant to the Heber Reorganization Plan. As to each Heber Debtor, a Claim or
Equity Interest shall be deemed classified in a particular Class or Subclass
only to the extent that the Claim or Equity Interest qualifies within the
description of that Class or Subclass and shall be deemed classified in a
different Class or Subclass to the extent that any remainder of the Claim or
Equity Interest qualifies within the description of such different Class or
Subclass. A Claim or Equity Interest is in a particular Class or Subclass only
to the extent that such Claim or Equity Interest is Allowed in that Class or
Subclass and has not been paid or otherwise settled prior to the Effective Date.

                                   ARTICLE IV

         The following is a designation of the treatment to be accorded, with
respect to each Heber Debtor, to each Class of Claims and Equity Interests
denominated in this Heber Reorganization Plan.

         As to each Heber Debtor, the treatment of and consideration to be
provided on account of Claims and Equity Interests pursuant to the Heber
Reorganization Plan shall be in full settlement, release and discharge of such
Claims and Equity Interests; provided, however, that such discharge shall not
affect the liability of any other entity to, or the property of any other entity
encumbered to secure payment to, the holder of any such Claim or Equity
Interest, except as otherwise provided in the Heber Reorganization Plan; and
provided, further, that such discharge shall not encompass the Heber Debtors'
obligations under this Heber Reorganization Plan.

         No Claim shall entitle the holder thereof to any Distribution pursuant
to this Heber Reorganization Plan unless, and only to the extent that, such
Claim is an Allowed Claim. All Distributions on account of Allowed Claims shall
be made on the applicable Distribution Date.

receive, in full settlement, release and discharge of its Class 1 Claim, either
(i) Cash, on the Distribution Date, in an amount equal to such Allowed Claim, or
(ii) such other less favorable terms as Covanta and the holder of an Allowed
Priority Non-Tax Claim agree; provided, however, that no agreement under
subsection (ii) above shall impose any obligation upon the Reorganized Heber
Debtors beyond the payment of amounts calculated in accordance with the Working
Capital Adjustment.

             c. Voting: Class 1 Claims are Unimpaired, and the holders of

             b. Treatment: The holder of the Allowed Subclass 2H-A Claims shall
retain, unaltered, the legal, equitable and contractual rights, including,
without limitation, any valid and perfected Liens that secure such Allowed
Claim, provided, however, that the assets of the Heber Debtors subject to the
GECC Liens may be sold, subject to such GECC Liens, as part of the Geothermal
Sale contemplated by this Heber Reorganization Plan; provided, further, if GECC
consents to the sale of the Equity Interests in SIGC Project Company pursuant to
Section 2.1 of the Alternative Transaction Purchase Agreement, the holder of
Allowed Subclass 2H-A Claims shall release any and all Liens, Claims and
encumbrances in the Equity Interests and assets of SIGC One Sub, SIGC Two Sub,
Amor and any other Debtors (other than SIGC Project Company).

         Covanta shall pay to each holder of an Allowed Subclass 2H-B Claim, in
full settlement, release and discharge of its Subclass 2H-B Claim, either (i)
Cash, on the Effective Date, in an amount equal to such Allowed Subclass 2H-B
Claim, or (ii) such other less favorable terms as Covanta and the holder of an
Allowed GECC Secured HGC/HFC Claim agree provided, however, that no agreement
under subsection (ii) above shall impose any obligation upon the Reorganized
Heber Debtors beyond the payment of amounts calculated in accordance with the
Working Capital Adjustment.

and will remain unaltered, except as the relevant Heber Debtor (or, on or after
the Effective Date, Reorganized Heber Debtor) and the holders of Allowed Class
3H Claims may otherwise agree or as such holders may otherwise consent.
Notwithstanding the foregoing, no contractual provisions or applicable law that
would entitle the holder of an Allowed Class 3H Claim to demand or receive
payment of such Claim prior to the stated maturity of such Claim, terminate any
contractual relationship or take such other enforcement action (as may be
applicable) from and after the occurrence of a default that occurred prior to
the Effective Date shall be enforceable against the Reorganized Heber Debtors.
In lieu of the foregoing, any Heber Debtor (or, on or after the Effective Date,
Reorganized Heber Debtor) may, at its election, make a Cash payment to the
holder of an Allowed Class 3H Claim equal to the full amount of the holder's
Allowed Class 3H Claim, together with interest at the legal rate to the extent

Claim.

                                   ARTICLE VI

                            MEANS FOR IMPLEMENTATION

         6.1 Implementation of the Geothermal Sale. The implementation of this
Heber Reorganization Plan is predicated upon the approval by the Court of the
Geothermal Sale, and the consummation thereof hereunder. The terms and
conditions of the Geothermal Sale and the Alternative Transaction Purchase
Agreeement are incorporated herein and shall be deemed to constitute part of
this Heber Reorganization Plan for all purposes. The following description of
the Geothermal Sale and summary of the Alternative Transaction Purchase
Agreement is qualified in its entirety by the terms thereof.

             (a) The Alternative Transaction Purchase Agreement provides for a
base Purchase Price of $214,000,000, which amount is subject to adjustment as
provided in the Alternative Transaction Purchase Agreement.

             (b) The Alternative Transaction Purchase Agreement provides for the
sale of the Equity Interests, which corresponds to all of the respective
ownership interests of the Debtor Sellers in the Heber Debtors. Subject to the
terms of the Confirmation Order and conditions of Section 2.1 of the Alternative
Transaction Purchase Agreement, if the Buyers obtain the consent of and release
from GECC, the Buyers may directly acquire the Equity Interests in the SIGC
Project Company rather than the Equity Interests in SIGC One Sub and SIGC Two
Sub.

             (c) As a condition to Closing, the Debtors must receive Court
approval of, among other things, the (i) sale of the Geothermal Business as
contemplated by the Alternative Transaction Purchase Agreement and (ii)
assumption and/or assignment by the respective Heber Debtors and other Debtors
of the contracts set forth in Schedules 3.3(a), 3.3(b) and 3.3(c) to the
Alternative Transaction Purchase Agreement and Exhibits B, C and D hereto,
including the O&M Contracts, by the relevant Debtors to the Buyers. In addition,
the Debtors shall have received formal approval of the DIP Lenders, consenting
to the consummation of the transactions contemplated in the Purchase Agreement
and releasing security interests granted to them pursuant to the DIP Security
Agreement.

             (d) Among other things, at the Closing, the following events shall
occur:

                 (i) Except as provided for in Section 2.1 of the Alternative
Transaction Purchase Agreement, the Debtor Sellers shall sell, convey, assign,
transfer and deliver their respective Equity Interests in SIGC One Sub, SIGC Two
Sub, HFC Project Company and HGC Project Company to the Buyers as provided in
the Alternative Transaction Purchase Agreement, which Equity Interests shall
continue to be evidenced by the existing Equity Interests;

                 (ii) Equity Interests in Amor and SIGC Project Company shall be
held by the Heber Debtor that originally held such Equity Interests, which
Equity Interests shall continue to be evidenced by the existing Equity
Interests;

                 (iii) Buyers shall deliver to the Sellers an amount that,
together with the Deposit, equals the Purchase Price, by wire transfer of
immediately available funds to an account designated by the Sellers;

                 (iv) the Heber Debtors will assume all executory contracts and
unexpired leases relating to the Geothermal Business to which they are parties
(except for contracts previously assumed), which contracts and leases will be
transferred to the Buyers through their acquisition of the ownership interests
in the Heber Debtors.

                 (v) Certain of the Debtor Sellers and certain of the Debtor
Operators will assume and assign certain contracts relating to the Geothermal
Business to the Buyers. The Debtor Operators will assign their previously
assumed O&M Contracts to the Buyers.

                 (vi) To the extent not already paid, Covanta shall cause all
undisputed Cure Amounts and HFC Settlement Payments to be paid to holder of such
Claims.

         6.2 Authorization of Transfer of Equity Interests. On the Effective
Date, the Debtor Sellers are authorized to sell, convey, assign, transfer and
deliver their respective Equity Interests in SIGC One Sub, SIGC Two Sub, HFC
Project Company and HGC Project Company without the need for further corporate
action, and in accordance with the Alternative Transaction Purchase Agreement.
Furthermore, Amor and SIGC Project Company shall be authorized to, and shall
reinstate, their respective Equity Interests. To the extent Buyers directly
acquire the Equity Interests in the SIGC Project Company rather than the Equity
Interests in SIGC One Sub and SIGC Two Sub in accordance with Section 2.1 of the
Alternative Transaction Purchase Agreement, SIGC Two Sub and Amor shall be
authorized to sell, convey, assign, transfer and deliver their respective Equity
Interests in the SIGC Project Company without the need for further corporate
action, and in accordance with the Alternative Transaction Purchase Agreement.

         6.3 Cancellation of Existing Securities and Agreements. Except for
purposes of evidencing a right to Distributions under this Heber Reorganization
Plan or as otherwise provided hereunder, on the Effective Date, all the
agreements and other documents evidencing (i) any Claims or rights of any holder
of a Claim against the applicable Heber Debtor, including all indentures and
notes evidencing such Claims and (ii) any options or warrants to purchase Equity
Interests, obligating the applicable Heber Debtor to issue, transfer or sell
Equity Interests or any other capital stock of the applicable Heber Debtor,
shall be cancelled without the need for further action; provided, however, that
notwithstanding the foregoing, the Reorganized Heber Debtors shall remain
obligated with respect to the GECC Liens and Permitted Encumbrances in property
of the Reorganized Heber Debtors, except to the extent such obligations have
been satisfied as of the Effective Date.

         6.4 Board of Directors and Executive Officers. Each of the directors
and/or officers of each of the Heber Debtors shall resign their positions on or
prior to the Effective Date. At or before the Confirmation Hearing, Buyers shall
comply with the applicable provisions of section 1129(a)(5) of the Bankruptcy
Code.

         6.5 Deemed Consolidation of Heber Debtors for Plan Purposes Only.
Subject to the occurrence of the Effective Date, the Reorganized Heber Debtors
shall be deemed consolidated solely for the following purposes under the Heber
Reorganization Plan: (i) as provided with respect to Class 14 Equity Interests,
no Distributions shall be made under the Heber Reorganization Plan on account of
Equity Interests in Amor and SIGC Project Company; and (ii) in some instances,
Claims against more than one Heber Debtor have been grouped together into a
single Class of Claims for distribution purposes.

         Such deemed consolidation, however, shall not affect: (i) the legal and
organizational structure of the Reorganized Heber Debtors; (ii) the ownership
interest of any Heber Debtor in any other Heber Debtor; and (iii) pre and
post-Petition Date guarantees, Liens and security interests that are required to
be maintained (a) in connection with executory contracts or unexpired leases
that were entered into during the Chapter 11 Cases or that have been or will be
assumed or (b) pursuant to this Heber Reorganization Plan or the instruments and
documents issued in connection herewith.

         6.6 Continued Corporate Existence; Vesting of Assets in the Reorganized
Heber Debtors and Corporate Restructuring. Each of the Heber Debtors shall, as a
Reorganized Heber Debtor, continue to exist after the Effective Date as a
separate legal entity, with all powers of a corporation or general or limited
partnership, as the case may be, under the laws of their respective states of
incorporation or organization and without prejudice to any right to alter or
terminate such existence (whether by merger or otherwise) under such applicable
state law. The Reorganized Heber Debtors shall be revested with their assets as
provided in Section 11.1 of this Heber Reorganization Plan, subject to the GECC
Liens and Permitted Encumbrances.

         6.7 [Intentionally Omitted.]

         6.8 Amended Organizational Documents. On the Effective Date, the
Reorganized Heber Debtors are authorized to, and shall, without the need for any
further corporate action, adopt and, as applicable, file their respective
amended organizational documents with the applicable Secretary of State. The
amended organizational documents shall prohibit the issuance of nonvoting equity
securities, as required by sections 1123(a) and (b) of the Bankruptcy Code,
subject to further amendment as permitted by applicable law.

         6.9 Settlements. Except to the extent the Court has entered a separate
order providing for such approval, the Confirmation Order shall constitute an
order (a) approving as a compromise and settlement pursuant to section
1123(b)(3)(A) of the Bankruptcy Code and Bankruptcy Rule 9019, any settlement
agreements entered into by any Heber Debtor or any other Person as contemplated
in confirmation of this Heber Reorganization Plan, and (b) authorizing the Heber
Debtors' execution and delivery of all settlement agreements entered into or to
be entered into by any Heber Debtor or any other Person as contemplated by this
Heber Reorganization Plan and all related agreements, instruments or documents
to which any Heber Debtor is a party.

         6.10 Payment of GECC Secured HGC/HFC Claims. On or prior to the

Bayerische Vereinsbank, AG, New York Branch and the lenders referred to therein,
as amended.

                                  ARTICLE VII
                                  DISTRIBUTIONS

         7.1 Distribution Record Date. As of the close of business on the
Distribution Record Date, the applicable Heber Debtors' books and records for
each of the Classes of Claims or Equity Interests as maintained by such Heber
Debtor or its respective agent, shall be deemed closed, and there shall be no
further changes in the record holders of any of the Claims or Equity Interests.
The applicable Heber Debtor shall have no obligation to recognize any transfer
of Claims or Equity Interests occurring on or after the applicable Distribution
Record Date. The applicable Heber Debtor shall be entitled to recognize and deal
for all purposes hereunder only with those record holders stated in the books
and records of the applicable Heber Debtor or its respective agent, as of the
close of business on the Distribution Record Date, to the extent applicable.

         7.2 Date of Distributions. Unless otherwise provided herein, any
Distributions and deliveries to be made hereunder shall be made on the Effective
Date or as soon thereafter as is practicable. In the event that any payment or
act under this Heber Reorganization Plan is required to be made or performed on
a date that is not a Business Day, then the making of such payment or the
performance of such act may be completed on the next succeeding Business Day,
but shall be deemed to have been completed as of the initial due date.

         7.3 Manner of Payment Under Plan. All Distributions of Cash to the
holders of Allowed Claims against each of the Heber Debtors under this Heber
Reorganization Plan shall be made as provided in this Heber Reorganization Plan
and shall be accounted for and adjusted between the parties to the Alternative
Transaction Purchase Agreement as and to the extent contemplated in accordance
with the applicable terms of the Working Capital Adjustment. Any Cash payments
may be accomplished by a check or wire transfer or as otherwise required or
provided in applicable agreements.

         7.4 Inquiries Concerning Distributions. Following the Effective Date,
requests for payment of Distributions, or inquiries with respect thereto, shall
be directed in the first instance to the Reorganized Heber Debtors. The
Reorganized Heber Debtors shall promptly inform Covanta of any such requests or
inquiries that relate to payments for which Covanta may be responsible.

         7.5 Surrender of Instruments. As a condition to receiving any
Distribution under this Heber Reorganization Plan, each holder of an Allowed
Claim represented by a certificated instrument or note must surrender such
instrument or note held by it to the applicable Reorganized Heber Debtor or its
designee at least ten (10) Business Days prior to the Effective Date, unless
such certificated instrument or note is being reinstated or being left
unimpaired under this Heber Reorganization Plan. Any entity that is so required
to surrender such instrument or note that fails to (i) surrender such instrument
or note or (ii) execute and deliver an affidavit of loss and/or indemnity
reasonably satisfactory to the applicable Reorganized Heber Debtor or furnish a
bond in form, substance and amount reasonably satisfactory to the applicable
Reorganized Heber Debtor before the first anniversary of the Effective Date,
shall be deemed to have forfeited all rights and Claims and may not participate
in any Distribution under this Heber Reorganization Plan in respect of such
Claim. Any other holder of an Allowed Claim who fails to take such action as
reasonably required by the Reorganized Heber Debtor or its designee to receive
its Distribution hereunder before the first anniversary of the Effective Date,
or such earlier time as otherwise provided for in this Heber Reorganization
Plan, may not participate in any Distribution under this Heber Reorganization
Plan in respect of such Claim. Any Distribution forfeited hereunder shall become
property of the Reorganized Heber Debtors. Upon the Effective Date, the GECC
Liens with respect to the Equity Interests in SIGC One Sub, SIGC Two Sub, Amor
and SIGC Project Company shall be deemed transferred to the Equity Interests in
such entities without further corporate action, in accordance with the terms of
the Alternative Transaction Purchase Agreement.

         7.6 Delivery of Distributions. Distributions to holders of Allowed
Claims shall be made at the Distribution Address. If any holder's Distribution
is returned as undeliverable, no further Distributions to such holder shall be
made unless and until Covanta is notified of such holder's then current address,
at which time all missed Distributions shall be made to such holder without
interest on or before one hundred and twenty (120) days after the date such
undeliverable Distribution was initially made. After such date, all unclaimed
property shall be used to satisfy the costs of administering and fully
consummating this Heber Reorganization Plan or become property of the applicable
Reorganized Heber Debtor, and the holder of any such Claim shall not be entitled
to any other or further distribution under this Heber Reorganization Plan on
account of such Claim.

         7.7 Exemption from Securities Laws. The issuance or transfer of any
securities pursuant to this Heber Reorganization Plan shall be exempt from any
securities laws registration requirements to the fullest extent permitted by
section 1145(a)(1)(A) of the Bankruptcy Code and section (3)(a)(7) of the
Securities Act of 1933.

         7.8 Setoffs. Each Heber Debtor may, in accordance with the provisions
of the Heber Reorganization Plan, section 553 of the Bankruptcy Code and
applicable non-bankruptcy law, set off against any Allowed Claim and the
Distributions to be made pursuant to this Heber Reorganization Plan on account
of such Allowed Claim (before any Distribution is made on account of such
Allowed Claim), the Claims, rights and causes of action of any nature that such
Heber Debtor may hold against the holder of such Allowed Claim; provided,
however, that neither the failure to effect such a setoff nor the allowance of
any Claim hereunder shall constitute a waiver or release by the applicable Heber
Debtor of any such Claims, rights and causes of action that the applicable Heber
Debtor may possess against such holder; and provided, further that any Claims of
each Heber Debtor arising before the Petition Date shall only be setoff against
Claims against such Heber Debtor arising before the Petition Date.

         7.9 Allocation of Plan Distribution Between Principal and Interest. All
Distributions in respect of any Allowed Claim shall be allocated first to the
principal amount of such Allowed Claim, as determined for federal income tax
purposes, and thereafter, to the remaining portion of such Allowed Claim, if
any.

         7.10 Withholding and Reporting Requirements. In connection with this
Heber Reorganization Plan and all instruments issued in connection therewith and
distributed thereon, any party making disbursements hereunder shall comply with
all applicable withholding and reporting requirements imposed by any federal,
state or local taxing authority, and all distributions under this Heber
Reorganization Plan shall be subject to any such withholding or reporting
requirements.

         7.11 Time Bar to Cash Payments. Checks issued in respect of Allowed
Claims shall be null and void if not negotiated within ninety (90) days after
the date of issuance thereof. Requests for reissuance of any check shall be made
to the party issuing such check by the holder of the Allowed Claim to whom such
check originally was issued. Any Claim in respect of such voided check shall be
made on or before thirty (30) days after the expiration of the sixty (60) day
period following the date of issuance of such check. After such date, all funds
held on account of such voided check may be used to satisfy the costs of
administering and fully consummating this Heber Reorganization Plan and shall be
subject to the applicable provisions of the Working Capital Adjustment, and the
holder of any such Allowed Claim shall not be entitled to any other or further
Distribution under this Heber Reorganization Plan on account of such Allowed
Claim.

         7.12 Closing of Chapter 11 Cases. As to each Heber Debtor, when
substantially all Disputed Claims have become Allowed Claims or have been
disallowed by Final Order, and all Distributions in respect of Allowed Claims
have been made in accordance with this Heber Reorganization Plan, or at such
earlier time as the Reorganized Heber Debtors deem appropriate, the Reorganized
Heber Debtors shall seek authority from the Court to close their respective
Chapter 11 Cases in accordance with the Bankruptcy Code and the Bankruptcy
Rules.

                                  ARTICLE VIII

              PROCEDURES FOR RESOLVING AND TREATING DISPUTED CLAIMS

         8.1 No Distribution Pending Allowance. Notwithstanding any other
provision of this Heber Reorganization Plan, no Cash shall be distributed under
this Heber Reorganization Plan on account of any Disputed Claim, unless and
until all objections to such Disputed Claim have been settled or withdrawn or
have been determined by Final Order and the Disputed Claim, or some portion
thereof, has become an Allowed Claim.

         8.2 Resolution of Disputed Claims and Equity Interests.

             (a) Unless otherwise ordered by the Court after notice and a
hearing, the Heber Debtors, Reorganized Heber Debtors and Covanta shall have the
exclusive right to make and file objections to Claims (other than Administrative
Expense Claims) and shall serve a copy of each objection upon the holder of the
Claim to which the objection is made as soon as practicable, but in no event
later than one hundred and twenty (120) days after the Effective Date; provided,
however, that such one hundred and twenty (120) day period may be automatically
extended by the Reorganized Heber Debtors, without any further application to,
or approval by, the Court, for up to an additional thirty (30) days. The
foregoing deadlines for filing objections to Claims shall not apply to Claims
for tort damages and, accordingly, no such deadline shall be imposed by this
Heber Reorganization Plan. Notwithstanding any authority to the contrary, an
objection to a Claim shall be deemed properly served on the holder thereof if
service is affected in any of the following manners: (i) in accordance with Rule
4 of the Federal Rules of Civil Procedure, as modified and made applicable by
Bankruptcy Rule 7004; (ii) by first class mail, postage prepaid, on the
signatory on the proof of claim or interest or other representative identified
in the proof of claim or interest or any attachment thereto; or (iii) by first
class mail, postage, on any counsel that has appeared on the holder's behalf in
the Chapter 11 Cases.

             (b) Except with respect to Administrative Expense Claims as to
which the Administrative Expense Claim Bar Date does not apply, Administrative
Expense Claims must be filed with the Court and served on counsel for the Heber
Debtors and Buyers on or before the Administrative Expense Claim Bar Date. The
Heber Debtors, Reorganized Heber Debtors, Covanta or the United States Trustee
may make and file objections to any such Administrative Expense Claim and shall
serve a copy of each objection upon the holder of the Claim to which the
objection is made as soon as practicable, but in no event later than one hundred
and eighty (180) days after the Effective Date. In the event that any such
objection is filed, the Court shall determine the Allowed amount of any such
Administrative Expense Claim.

         8.3 Estimation of Claims and Equity Interests. The Heber Debtors,
Reorganized Heber Debtors or Covanta may at any time request that the Court
estimate any contingent, unliquidated or Disputed Claim pursuant to section
502(c) of the Bankruptcy Code, regardless of whether such requester has
previously objected to such Claim or whether the Court has ruled on any such
objection, and the Court will retain jurisdiction to estimate any Claim at any
time during litigation concerning any objection to any Claim. In the event that
the Court estimates any Disputed Claim, that estimated amount may constitute
either the Allowed amount of such Claim or a maximum limitation on such Claim,
as determined by the Court. If the estimated amount constitutes a maximum
limitation on such Claim, the Heber Debtors, Reorganized Heber Debtors or
Covanta, as the case may be, may elect to pursue any supplemental proceedings to
object to any ultimate payment of such Claim. All of the aforementioned Claims
objection, estimation and resolution procedures are cumulative and not
necessarily exclusive of one another.

         8.4 Reserve Account for Disputed Claims. Following the Effective Date,
Covanta shall hold in one or more Disputed Claims Reserves, for each Class in
which there are any Disputed Claims, Cash in an aggregate amount sufficient to
pay to each holder of a Disputed Claim the amount of Cash that such holder would
have been entitled to receive pro rata under this Heber Reorganization Plan if
such Claim had been an Allowed Claim in such Class. Cash withheld and reserved
for payments to holders of Disputed Claims in any Class shall be held and
deposited in one or more segregated interest-bearing reserve accounts for each
Class of Claims in which there are Disputed Claims entitled to receive Cash, to
be used to satisfy the Disputed Claims if and when such Disputed Claims become
Allowed Claims.

         8.5 Allowance of Disputed Claims. With respect to any Disputed Claim
that is subsequently deemed Allowed, on the Distribution Date for any such
Claim, Covanta shall distribute from the Disputed Claims Reserve Account
corresponding to the Class in which such Claim is classified to the holder of
such Allowed Claim the amount of Cash that such holder would have been entitled
to recover pro rata under this Heber Reorganization Plan if such Claim had been
an Allowed Claim on the Effective Date, together with such claimholder's Pro
Rata Class Share of net interest, if any, on such Allowed Claim. For purposes of
the immediately preceding sentence, such holder's Pro Rata Class Share of net
interest shall be calculated by multiplying the amount of interest on deposit in
the applicable Disputed Claims Reserve account on the date immediately preceding
the date on which such Allowed Claim is to be paid by a fraction, the numerator
of which shall equal the amount of such Allowed Claim and the denominator of
which shall equal the amount of all Claims for which deposits are being held in
the applicable Disputed Claims Reserve account on the date immediately preceding
the date on which such Allowed Claim is to be paid.

         8.6 Release of Funds from Disputed Claims Reserve. If at any time or
from time to time after the Effective Date, there shall be Cash in a Disputed
Claims Reserve account in an amount in excess of the maximum remaining payment
obligations to the then existing holders of Disputed Claims in the Class of
Claims corresponding to such Disputed Claims Reserve account under this Heber
Reorganization Plan, such excess funds, and the Pro Rata Class Share of net
interest in respect thereof, shall become property of Covanta.

         8.7 Cure Amounts with respect to Executory Contracts or Unexpired
Leases. Disputes concerning cure amounts arising from executory contracts or
unexpired leases assumed by the Heber Debtors shall be governed by Sections 9.3
and 9.9 of this Heber Reorganization Plan.

                                   ARTICLE IX

                             TREATMENT OF EXECUTORY
                         CONTRACTS AND UNEXPIRED LEASES

         9.1 Heber Debtor Contracts. Except for any contract or lease that (a)
has been previously assumed or rejected pursuant to a Final Order of the Court,
(b) is specifically designated as a contract or lease on the Schedule of
Rejected Contracts and Leases, or (c) is the subject of a separate motion to
assume or reject filed under section 365 of the Bankruptcy Code by one of the
Debtors on or prior to the Confirmation Hearing, upon the Effective Date, all
Heber Debtor Contracts, including the Heber Debtor Contracts identified on
Exhibit B attached hereto and the mineral rights leases and related agreements
identified on Exhibit C attached hereto, shall be deemed assumed by the Heber
Debtor that is a party to such Heber Debtor Contract; provided, however, that to
the extent the Buyers directly acquire the Equity Interests in the SIGC Project
Company rather than the Equity Interests in SIGC One Sub and SIGC Two Sub in
accordance with Section 2.1 of the Alternative Transaction Purchase Agreement,
any Heber Debtor Contracts to which a Holding Company is a party will be assumed
by the relevant Heber Debtor and assigned to the SIGC Project Company. Any
affiliate of a Heber Debtor that is a party to a Heber Debtor Contract shall
assume such Heber Debtor Contract and assign its rights and obligations under
such Heber Debtor Contract to Buyers at Closing, provided that such Heber Debtor
Contract is assumed pursuant to this Heber Reorganization Plan. The listing of a
document on Exhibits B or C hereto shall not constitute an admission that such
document is an executory contract or unexpired lease or that the Heber Debtors
have any liability thereunder. The Heber Debtors may amend, with the consent of
Buyers, Exhibits B or C to add or delete any contract or lease at or prior to
the Confirmation Hearing. Additionally, upon the Effective Date, the Heber
Debtor Contracts identified on Exhibit F hereto, which previously have been
assumed by Final Order of the Court, shall be transferred through the transfer
of Equity Interests to the applicable Buyer pursuant the terms of the
Alternative Transaction Purchase Agreement.

         9.2 Additional Contracts. Certain of the Debtor Sellers, certain of the
Debtor Operators, and certain other Debtors are also parties, along with the
Heber Debtors, to certain of the Heber Debtor Contracts or parties to various
other contracts relating to the Geothermal Business. Such Additional Contracts
are identified on Exhibit D attached hereto. In accordance with section 365(f)
of the Bankruptcy Code, upon the Effective Date, the Additional Contracts shall
be assumed by the relevant Debtors and assigned to the applicable Buyer pursuant
to the terms of the Alternative Transaction Purchase Agreement. In addition,
upon the Effective Date, the Debtor Operators shall assign to Buyers the O&M
Contracts identified on Exhibit E. The listing of a document on Exhibits D or E
hereto shall not constitute an admission that such document is an executory
contract or unexpired lease or that the Heber Debtors have any liability
thereunder. The Heber Debtors may amend, with the consent of Buyers, Exhibits D
or E to add or delete any contract or lease at or prior to the Confirmation
Hearing.

         9.3 Cure of Defaults. Exhibits B, C, D and E hereto set forth the Cure
Amounts determined by the Heber Debtors and the Debtors, based upon a review of
their books and records and the relevant documents, necessary to cure any and
all defaults existing under each of the contracts identified therein pursuant to
section 365(b) of the Bankruptcy Code. The Cure Amounts shall be final and
binding on parties identified on Exhibits B, C, D and E hereto (or their
successors and assigns) and shall not be subject to further dispute or audit
based on performance prior to the time of assumption, irrespective of whether
such assumed executory contract or unexpired lease contains an audit clause;
provided, however, that the terms of the HFC Royalty Settlement Order shall
control the Cure Amounts owed to parties to the HFC Royalty Settlement,
including Cure Amounts fixed in additional settlement agreements contemplated
and authorized by such Order. The holders of Heber Royalty Settled Claims shall
be entitled to receive both the Cure Amounts and the HFC Royalty Settlement
Payments.

         9.4 Objections. Any objection to (i) assumption, assignment or
rejection of the contracts or leases pursuant to this Heber Reorganization Plan
or (ii) Cure Amounts must be in writing, shall state with particularity the
reasons for the objection or response, and shall be filed with the Court and
served upon co-counsel to the Debtors, Cleary, Gottlieb, Steen & Hamilton, One
Liberty Plaza, New York, New York 10006, Attention: James L. Bromley, Esq., and
Jenner & Block LLC, One IBM Plaza, Chicago, Illinois 60611, Attention: Vincent
E. Lazar, Esq., so as to be filed and received by 4:00 p.m. (Prevailing Eastern
Time) on or before seven (7) days prior to the Confirmation Hearing. Only those
objections that have been timely filed and served may be considered by the Court
at the Confirmation Hearing. Any objection as to Cure Amounts must state with
specificity the Cure Amount the objecting party believes is required and provide
appropriate documentation in support thereof. If no objection to a particular
Cure Amount is timely received, the Cure Amount set forth on Exhibits B, C, D or
E shall be controlling notwithstanding anything to the contrary in any such
contract or lease, and the counterparty thereto shall be forever barred from
asserting any other claim arising prior to the assumption or assumption and
assignment against the Debtors, the Heber Debtors, the Reorganized Heber Debtors
or the Buyer as to such Cure Amounts; provided, however, that the terms of the
HFC Royalty Settlement Order shall control the Cure Amounts owed to parties to
the HFC Royalty Settlement, including Cure Amounts fixed in additional
settlement agreements contemplated and authorized by such Order. In the event of
a dispute regarding any Cure Amount or the ability of the Heber Debtor or other
Debtors to assume and/or assign a particular contract or lease, including
providing adequate assurance of future performance, the applicable Debtor may
determine to reject such contract or lease and otherwise will provide for
payments required by section 365(b)(1) of the Bankruptcy Code only after the
entry of a Final Order resolving such dispute.

         9.5 Approval of Assumption of Certain Executory Contracts. Subject to
Sections 9.1, 9.2 and 9.3 of this Heber Reorganization Plan, the executory
contracts and unexpired leases of the Debtors listed on Exhibits B, C, D and E
hereto shall be assumed by the relevant Debtors and, as applicable, assigned to
the relevant Buyer as of the Effective Date. Except as may otherwise be ordered
by the Court, the Heber Debtors shall have the right to cause any assumed
executory contract or unexpired lease to vest in the Reorganized Heber Debtor
designated for such purpose by the Heber Debtors.

         9.6 Approval of Rejection of Executory Contracts and Unexpired Leases.
Entry of the Confirmation Order shall constitute the approval, pursuant to
section 365(a) of the Bankruptcy Code, of the rejection of any executory
contracts and unexpired leases to be rejected as and to the extent provided in
Section 9.1 of this Heber Reorganization Plan.

         9.7 Deemed Consents. Unless a counterparty to an executory contract,
unexpired lease, license or permit objects to the applicable Debtor's assumption
thereof in writing on or before seven (7) days prior to the Confirmation
Hearing, then, unless such executory contract, unexpired lease, license or
permit has been rejected by the applicable Debtor or will be rejected by
operation of the Heber Reorganization Plan, the Reorganized Heber Debtors shall
enjoy all the rights and benefits under each such executory contract, unexpired
lease, license and permit without the necessity of obtaining such counterparty's
written consent to assumption or retention of such rights and benefits.

         9.8 Bar Date for Rejection Damage Claims. Claims arising out of the
rejection of an executory contract or unexpired lease pursuant to Section 9.1 of
this Heber Reorganization Plan, if any, must be filed with the Court no later
than the later of (i) fifteen (15) days after the Effective Date, and (ii)
fifteen (15) days after entry of an order rejecting such executory contract or
lease. Any Claims not filed within such time period will be forever barred from
assertion against any of the Debtors, the Heber Debtors or the Reorganized Heber
Debtors.

         9.9 Cure Amount Disputes. Upon agreement by the parties to the
Alternative Transaction Purchase Agreement and without prejudice to Buyers
rights under the Alternative Transaction Purchase Agreement, any executory
contract or unexpired lease that is subject to a Cure Amount dispute may be
added by the Heber Debtors or Reorganized Heber Debtors to the Schedule of
Rejected Contracts and Leases at any time, including, without limitation, after
the resolution by the Court of such Cure Amount dispute, regardless of the
occurrence of the Confirmation Date or the Effective Date, based on the
existence of such dispute.

                                   ARTICLE XI

Estate shall vest in the applicable Reorganized Heber Debtor free and clear of
all Claims, Liens, encumbrances, charges and other interests, except with

(vi) taking any actions to interfere with the implementation or consummation of
this Heber Reorganization Plan; provided that nothing herein shall prohibit any

assets, properties, successors in interest, affiliates or assigns have any
liability or obligation for any Claim against or Equity Interest in any of the

the provisions of this Heber Reorganization Plan. In addition, except as
otherwise provided in this Heber Reorganization Plan or the Confirmation Order,

Plan. By accepting Distributions pursuant to this Heber Reorganization Plan,
each holder of an Allowed Claim or Allowed Equity Interest receiving
Distributions pursuant to the Heber Reorganization Plan will be deemed to have
specifically consented to the injunctions set forth herein.
