         SECTION 3.2 Initial Purchase Price. The initial purchase price for the
Purchased Shares shall be Seventy One Million Dollars ($71,000,000) (the

Price shall be subject to such adjustments as are specified in Section 3.4,
Section 3.5, Section 7.5, Section 7.6 and ARTICLE 9, if any (the Initial
Purchase Price as so adjusted is herein referred to as the "Purchase Price").

         SECTION 3.4 Estimated Adjustment Statement.

                   (a) By or before 10:00 a.m. on the third Business Day prior
to the scheduled Closing Date, Seller shall prepare and deliver to Purchaser a
statement (the "Estimated Adjustment Statement") that sets forth as of the close
of business on the Closing Date the net working capital of the Companies as of
the Closing Date as calculated as set forth on Schedule 3.4; provided, however
the following shall be excluded from such calculation: (i) any and all
liabilities under the Loan Documents; and (ii) any amounts related to Inventory;
and (iii) the Intercompany Arrangements. In connection with the foregoing
calculation, Seller shall also determine any and all costs, expenses or other
liabilities paid by any of the Companies prior to the Closing Date and any of
the foregoing accrued by any of the Companies prior to the Closing Date related
to the repairs contemplated by Item 1 of Schedule 5.19 prior to the Closing Date
and all such accrued unpaid amounts shall be included in the calculation of net

Seller and Purchaser as provided in

                                       16




Section 7.7. In the event the Closing is not scheduled to occur on the last day
of a given month, then the items that are included in the Estimated Adjustment
Statement shall be prorated to the extent applicable as of the Closing Date by
multiplying the amount of each such item representing the full calendar month by
a fraction, the numerator of which is the Closing Date and the denominator of
which is the number of days there are in the month in which the Closing occurs.
The Estimated Adjustment Statement will be prepared in conformity with GAAP,
applied on a basis consistent with the financial statements made available to
Purchaser under Section 5.17, using the example and format set forth in Schedule
3.4.

                   (b) In the event the result of the Estimated Adjustment
Statement is a negative number, then the Initial Purchase Price will be reduced
by an amount equal to absolute value of such number and if the result is a
positive number, then the Initial Purchase Price will be increased by an amount
equal to such number.

         SECTION 3.5 Final Adjustment Statement.

                   (a) Within forty-five (45) days following the Closing Date,
Purchaser shall prepare and deliver to Seller a final statement (the "Final
Adjustment Statement") that sets forth the same information as included in the
Estimated Adjustment Statement provided pursuant to Section 3.4(a) above,
adjusted to take into account the final figures as of 12:01 a.m. on the Closing
Date determined in accordance with the standard set forth in Section 3.4. Seller
shall provide to Purchaser copies of all invoices or other billing information
actually received or sent by Seller during this forty-five (45) day period to
allow Purchaser 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 are reasonably required in order for Seller to
understand and verify the accuracy of the computation of the amount(s) set forth
therein. In the event the Closing does not occur on the last day of a given
month, then the items that are included in the Final Adjustment Statement shall
be prorated to the extent applicable as of the Closing Date by multiplying the
amount of each such item representing the full calendar month by a fraction, the
numerator of which is the Closing Date and the denominator of which is the
number of days there are in the month in which the Closing occurs.

                   (b) The Parties shall attempt to agree upon the Final
Adjustment Statement within thirty (30) days following the delivery thereof to
Seller. If Seller disputes any item set forth on the Final Adjustment Statement,
Seller shall give Purchaser written notice thereof within thirty (30) days
following the delivery to Seller of the Final Adjustment Statement setting forth
in reasonable detail the disputed item or items. If Seller has not delivered
such notice to Purchaser 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 Initial Purchase Price that
is different from the adjustment calculated pursuant to Section 3.4(a), the
Party that benefited from

                                       17



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 Seller has delivered a notice of a dispute to
Purchaser, the undisputed portion of the variance amount, if any, shall be paid
to the Party entitled to receive the same within five (5) Business Days
following the delivery of the notice by Seller to Purchaser, and the Parties
shall jointly engage the Independent Accounting Firm and shall direct the
Independent Accounting Firm to make a final, binding determination of all such
disputes within forty-five (45) days of presentation to the Independent
Accounting Firm 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 Independent Accounting Firm within ten (10)
days following the selection thereof. The Parties will further direct the
Independent Accounting Firm to deliver a written notice to Purchaser and Seller
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 Accounting
Firm's notice of its determination. The fees and expenses of the Independent
Accounting Firm shall be borne in equal parts by the Purchaser on the one hand,
and the Seller, on the other, and further agree that in connection with the
engagement of the Independent Accounting Firm, each of the Purchaser and the
Seller will, if requested by the Auditors, execute a reasonable engagement
letter including customary indemnities.

                  (a) violate, or conflict with, or result in a breach of any
provisions of the certificate of incorporation or by-laws of Seller or COSI
PUNA;

                  (b) result in a default (or give rise to any right of

been, or prior to the Closing will have been, obtained;

                  (c) violate, contravene or conflict with, or result in a
breach of, any law, rule, regulation, order, writ, injunction, license, permit

         SECTION 4.5 Brokers. All negotiations relating to this Agreement or the
Transactions for the benefit of Seller, COSI PUNA or the Companies have been

brokerage commission, finder's fee or other like payment to any Person.

         SECTION 4.6 Seller's and COSI PUNA's Qualifications. Neither Seller nor

any Governmental Authority which could result in a Material Adverse Effect.

                             COVENANTS OF EACH PARTY

         SECTION 7.1 Efforts to Close.

                  (a) Subject to this Section 7.1, each of the Parties agrees to
use its commercially reasonable efforts to consummate and make effective, as
soon as reasonably practicable, and in any event on or prior to the date that is
one hundred (100) days from the Effective Date, the Transactions, including, but
not limited to, the satisfaction of all conditions thereto set forth herein.
Such actions shall include exerting their commercially reasonable efforts to
obtain the consents, authorizations and approvals of all private parties and any
Governmental Authority whose consent is reasonably necessary to effectuate the
Transactions, including, in the case of Seller, Seller's Required Regulatory
Approvals and Seller's Required Consents, and in the case of Purchaser,
Purchaser's Required Regulatory Approvals and Purchaser's Required Consents, and
effecting all other necessary registrations and filings, including filings under
Applicable Laws, including the HSR Act, and all other necessary filings with any
Governmental Authority. In furtherance of this Section 7.1, each Party shall
designate a representative to act as the primary point of contact for all
communications between the Parties between the Effective Date and the Closing
Date with respect to this Agreement and the Transactions.

                  (b) All appearances, presentations, briefs, and proposals made
or submitted by or on behalf of either Party before any Governmental Authority
in connection with the approval of this Agreement or the Transactions shall be
subject to the joint approval or disapproval in advance and the joint control of
the Parties, acting with the advice of their respective counsel, and each Party
will consult and fully cooperate with the other Party, and consider in good
faith the views of the other Party, in connection with any such appearance,
presentation, brief, or proposal; provided, however, that nothing will prevent a
Party from responding to a subpoena or other legal process as required by law or
submitting factual information in response to a request therefor. Each Party
will provide the other with copies of all written communications from
Governmental Authorities relating to the approval or disapproval of this
Agreement or the Transactions.

         SECTION 7.2 Updating. Each Party shall promptly notify the other Party
of any changes or additions to any of the Schedules to this Agreement provided
by such Party, if any, to correct any matter that would constitute a breach of
any representation or warranty of such Party in Articles 4, 5 or 6, as the case
may be, of this Agreement as of a reasonably current date prior to the Closing,
but in any event not later than three (3) Business Days prior thereto. Subject
to Section 13.13, no such updates made pursuant to this Section 7.2 shall be
deemed to cure any inaccuracy of any representation or warranty made in this
Agreement as of the date hereof, unless the Party for whose benefit such
representation or warranty was made specifically agrees thereto in writing, nor
shall any



                                       34


such notification be considered to constitute or give rise to a waiver by the
Party for whose benefit such representation or warranty was made of any
condition set forth in this Agreement; provided, however, that if the Closing
shall occur, then all matters disclosed by either Party pursuant to any such
change or addition at or prior to the Closing shall be deemed to be matters of
which the other Party had Knowledge for purposes of Section 13.13. Each Party
agrees to advise the other Party promptly in writing of any matter or occurrence
of which it has or obtains Knowledge which may constitute a breach by either
Party of any representation, warranty or covenant contained in this Agreement,
or of any reason of which it has or obtains Knowledge why a condition to the
performance of either Party's obligations hereunder may not be satisfied on or
before the Closing Date.

liable for the obligations of, or make any loans or advances to, any Person,
except obligations for loans or advances from Seller or any of its Affiliates;
or (F) authorize, declare, or pay any cash dividend or any other similar
distribution to Seller or any Affiliate of Seller other than as payment for
goods and services rendered in the ordinary course, including, but not limited
to, payments made pursuant to Section 7.19.

                       (v) not take any action or enter into any commitment with
respect to or in contemplation of any liquidation, dissolution,
recapitalization, reorganization, or other winding up of its Business;

                       (vi) not change its accounting policies or practices
(including, without limitation, any change in depreciation or amortization
policies), except as required under GAAP;

                       (vii) not enter into any employment agreement not
terminable at will and will not increase any compensation of the Transferred
Employees other than in the ordinary course of business;

                       (viii) not grant any express Encumbrance on any assets of
PGV, except to the extent (i) required or permitted incident to the operation of
the assets of PGV and the business of PGV in the ordinary course of business of
PGV, or (ii) required or evidenced by any Existing Contract;

                       (ix) maintain in force and effect the Company Insurance
Policies; and

                       (x) not take any action which would cause any of Seller's
representations and warranties set forth in Articles 4 and 5 to be incorrect in
any material respect as of the Closing.

                  (b) Notwithstanding anything to the contrary in Section
7.3(a), Seller shall not be (i) obligated to make or cause PGV to make
expenditures other than in the ordinary course of business consistent with past
practices or to otherwise suffer any economic detriment, or (ii) precluded from,
and PGV shall not be precluded from, instituting, participating in or completing
any program designed to promote compliance or comply with Applicable Laws or
other good business practices with respect to the Plant; provided, however, that
notwithstanding anything to the contrary in Section 7.3(a), Seller may take or
may cause PGV to take (w) actions which are required by Applicable Law, (x)
reasonable actions in connection with any emergency or other force majeure
event, or (y) actions otherwise contemplated by this Agreement or disclosed in
Schedule 7.3(b) or any other Schedule to this Agreement.

                                       36


         SECTION 7.4 Regulatory Approvals.

                  (a) As promptly as practicable but in no event later than the
twentieth (20th) day after the date of the execution and delivery of this
Agreement, Seller and Purchaser shall each file or cause to be filed with the
Federal Trade Commission and the Department of Justice all notifications
required to be filed under the HSR Act and the rules and regulations promulgated
thereunder with respect to the Transactions. The Parties shall consult with each
other as to the appropriate time of filing such notifications and shall agree in
good faith upon the timing of such filings, respond promptly to any requests for
additional information made by either of such agencies, and cause the waiting
periods under the HSR Act to terminate or expire at the earliest possible date
after the date of filing. All filing fees to be paid in connection with such
filing shall be borne by the Purchaser.

                  (b) Subject to Section 7.1, Seller and Purchaser shall
cooperate with each other and (i) promptly prepare and file all necessary
documentation, (ii) effect all necessary applications, notices, petitions and
filings and execute all agreements and documents, and (iii) use all commercially
reasonable efforts to obtain all necessary consents, approvals and
authorizations of all other parties, in the case of each of the foregoing
clauses (i), (ii) and (iii), necessary or advisable to consummate the
Transactions. Seller and Purchaser shall use their best efforts to file for all
Seller's Required Regulatory Approvals and Purchaser Required Regulatory
Approvals, respectively, within thirty (30) days after the Effective Date.
Seller shall have the right to review and approve in advance all
characterizations of the information relating to PGV or its assets; and each of
Seller and Purchaser shall have the right to review in advance all
characterizations of the information relating to the Transactions which appear
in any filing made in connection with the Transactions.

                  (c) Without limiting the generality of Purchaser's
undertakings pursuant to Sections 7.4(a) and 7.4(b):

                       (i) Purchaser shall promptly take any or all of the
following actions to the extent necessary to eliminate any concerns on the part
of any Governmental Authority regarding the legality of Purchaser's acquisition
of the Purchased Shares under any Applicable Laws: (A) enter into negotiations;
(B) provide information; (C) make proposals; or (D) enter into and perform
agreements or submit to judicial or administrative orders, whether before or
after the Closing; and

                       (ii) Purchaser and Seller shall use commercially
reasonable efforts (including taking the steps contemplated by Section
7.4(b)(i)) to prevent the entry, in a judicial or administrative proceeding
brought under any Applicable Laws by any Governmental Authority or any other
party, of a permanent or preliminary injunction or other order that would make
consummation of the Transactions unlawful or that would otherwise prevent or
delay such consummation; and

                                       37


                       (iii) Purchaser and Seller shall promptly take, in the
event that such an injunction or order has been issued in such a proceeding, any
and all reasonable steps, including the appeal thereof, the posting of a bond,
or the steps contemplated by Section 7.4(b)(i), necessary to vacate, modify, or
suspend such injunction or order so as to permit such consummation on a schedule
as close as possible to that contemplated by this Agreement.

                  (d) Purchaser shall have the primary responsibility for
securing any required transfer, reissuance or procurement of the Permits
effective as of the Closing Date. Seller shall use commercially reasonable
efforts to cooperate with Purchaser's efforts in this regard and assist in any
transfer or reissuance of Permits.

         SECTION 7.5 Tax Matters.

                  (a) All Transfer Taxes incurred in connection with this
Agreement and the Transactions, whether levied on Purchaser or Seller, shall be
paid by Purchaser when due. Purchaser will file, to the extent required by
Applicable Laws, all necessary Tax Returns and other documentation with respect
to all such Transfer Taxes. To the extent required by Applicable Laws, but
subject to such review and approval, Seller or any of its Affiliates will join
in the execution of any such Tax Returns or other documentation. Seller will be
entitled to review in advance such Tax Returns as it or its Affiliates may be
required to join and execute and such Tax Returns shall be subject to Seller's
approval (which shall not be unreasonably withheld, conditioned or delayed).

                  (b) As soon as practicable after the Closing, Seller and
Purchaser agree to join in making a timely, effective and irrevocable election
under Section 338(h)(10) of the Code and the comparable election under the laws
of the State of Hawaii with respect to CE PUNA I and CE PUNA II (the "Section
338(h)(10) Election"). At least two (2) days prior to the Closing Date, Seller
shall deliver to Purchaser two Internal Revenue Service Forms 8023 with respect
to CE PUNA I and CE PUNA II. At the Closing Seller shall deliver to Purchaser
executed versions of such forms, which Purchaser shall counter-execute and file
with the IRS within two (2) weeks thereafter. Purchaser shall use commercially
reasonable efforts to deliver to CPI within 90 days after the Closing Date, but
in any event Purchaser shall deliver to CPI within 120 days after the Closing
Date, a statement (the "338 Allocation Statement") allocating the ADSP (as such
term is defined in Treasury regulations Section 1.338-4) of the assets of CE
PUNA I and CE PUNA II in accordance with the Treasury regulations promulgated
under Section 338 of the Code. Purchaser shall deliver a revised 338 Allocation
Statement to account for any adjustment to the Purchase Price pursuant to
Article 3 that was not previously taken into account in the preparation of the
338 Allocation Statement within 10 days after the payment of such Purchase Price
adjustment. CPI shall have the right to review the 338 Allocation Statement for
compliance with the Treasury regulations promulgated under Section 338 and
Section 755 of the Code. The parties agree that the ADSP (including any revised
ADSP) will be allocated in accordance with Schedule 7.5(b). If



                                       38


CPI notifies Purchaser in writing within 30 days after receipt of the 338
Allocation Statement or a revised 338 Allocation Statement that the allocation
of one or more items reflected in the 338 Allocation Statement or a revised 338
Allocation Statement does not comply with the Treasury regulations promulgated
under Section 338 and Section 755 of the Code, Purchaser and CPI will negotiate
in good faith to resolve such dispute. Upon resolution of the disputed items,
the allocation reflected on the 338 Allocation Statement (as such may have been
adjusted) shall be the "Price Allocation" and shall be binding on the parties
except as set forth herein. Seller and Purchaser agree to act in accordance with
the Price Allocation in the preparation, filing and audit of any Tax return. No
Party hereto shall file any form or document required to effect a valid and
timely Section 338(h)(10) Election (or similar state or local election),
including Internal Revenue Service Forms 8023 and 8883, any similar form under
any Applicable Laws and any schedules or attachments thereto, unless it shall
have obtained the consent of the other Party hereto, which consent shall not be
unreasonably withheld, conditioned or delayed, or otherwise required pursuant by
a "determination" within the meaning of Section 1313 of the Code. As soon as
practicable after the Closing, Seller will make a timely election under Section
754 of the Code for PGV and CE PUNA LP. Within two (2) weeks of making such
elections, Seller will provide copies of such elections to Purchaser.

                  (c) Any Tax Return to be prepared pursuant to the provisions
of this Section 7.5 shall be prepared in a manner consistent with practices
followed in prior years with respect to similar Tax Returns, except for changes
required by changes in Applicable Laws or fact. Purchaser shall not file an
amended Tax Return for any period ending on or prior to the Closing Date without
the consent of CPI, which consent shall not be unreasonably withheld,
conditioned or delayed. The filing of any Tax Returns, or the payment of any
Taxes, described in this Section 7.5 shall be made on a timely basis in
accordance with Applicable Laws. The following provisions shall govern the
allocation of responsibility as between the Parties for certain Tax matters
following the Closing Date:

                       (i) CPI shall prepare or cause to be prepared and file or
cause to be filed all Tax Returns for the Companies for all periods ending on or
prior to the Closing Date regardless of when such Tax Returns are to be filed.
CPI shall pay, or cause to be paid, the Taxes attributable to the Companies with
respect to such periods (including any Income Taxes resulting from the
338(h)(10) Election), other than Transfer Taxes incurred in connection with this
Agreement and the Transactions, which shall be the responsibility of Purchaser.

                       (ii) Purchaser shall prepare or cause to be prepared and
file or cause to be filed any Tax Returns of the Companies for Tax periods which
begin before or on the Closing Date and end after the Closing Date, excluding
those returns for which a Tax Return must be filed for a short year return
ending on or prior to the Closing Date, which shall be subject to subparagraph
(i) above. To the extent that such Taxes have not been included as a liability
on the Final Adjustment Statement, Seller shall pay, or cause


                                       39


to be paid, to Purchaser within fifteen (15) days after the date on which Taxes
are paid with respect to such periods an amount equal to the portion of such
Taxes, which relates to the portion of such Tax period ending on the Closing
Date, other than Transfer Taxes incurred in connection with this Agreement and
the Transactions, which shall be the responsibility of Purchaser.

                  (d) Each Party shall provide the other Party with such
assistance as may reasonably be requested by the other Party in connection with
the preparation of any Tax Return, or any audit or other examination by any
taxing authority, or any judicial or administrative proceedings relating to any
liability for Taxes (a "Tax Proceeding"), and each will retain and provide the
requesting Party with any records or information which may be relevant to such
Tax Return or Tax Proceeding. Any reasonable out-of-pocket expenses incurred in
providing such assistance shall be borne by the requesting party. Any
information obtained pursuant to this Section 7.5 or pursuant to any other
Section hereof providing for the sharing of information relating to or review of
any Tax Return or other schedule relating to Taxes shall be kept confidential by
the Parties in accordance with the Confidentiality Agreement.

                  (e) After the Closing Date, in the case of any Tax Proceeding
with respect to a Taxable period for which Seller is or may be liable for the
Taxes pursuant to this Agreement, other than a claim for Taxes or a Purchaser
Claim described in Section 7.5(f) or (g), Purchaser shall inform Seller within
ten (10) days of the receipt of any notice of such Tax Proceeding, and shall
afford Seller, at Seller's expense, the opportunity to control the conduct of
such Tax Proceedings. Purchaser shall execute or cause to be executed powers of
attorney or other documents necessary to enable Seller to take all actions
desired by Seller with respect to such Tax Proceeding. Seller shall have the
right to control, in its sole discretion, any such Tax Proceedings and to
initiate any claim for refund, file any amended return, pay such Taxes, or enter
into any settlement agreement with a Governmental Authority, or take any other
action which it deems appropriate with respect to such Taxes; provided, however,
that Seller shall not, without Purchaser's consent (which consent shall not be
unreasonably withheld, conditioned or delayed) agree to any settlement with
respect to any Tax if such settlement would adversely affect the Tax liability
of Purchaser.

                  (f) Notwithstanding any other provision of this Agreement,
this Section 7.5(f) and Section 7.5(g), the dollar limitations contained in
Section 9.2(b), the dollar threshold contained in Section 9.7(c), and the time
limitations contained in Section 9.10 shall apply to indemnifications by Seller
to Purchaser for, and such indemnification shall be the sole remedy of Purchaser
in respect of, the Losses in respect of Taxes. Seller shall indemnify and hold
harmless Purchaser and the Companies from and against the entirety of any and
all Losses that Purchaser may suffer for any Taxes attributable to the Companies
with respect to any Tax year or portion thereof ending on or before the Closing
Date (or for any Tax year beginning before and ending after the Closing Date to

                                       40


the extent allocable to the portion of such period beginning before and ending
on the Closing Date).

                  (g) The provisions of this Section 7.5(g) shall apply only to
the indemnification provided for under Section 7.5(f) and a Purchaser Claim with
respect to Taxes. If a Purchaser Claim exists for Taxes or if a claim for Taxes
is made against Purchaser for which Purchaser intends to seek indemnity with
respect thereto under Section 7.5(f), Purchaser shall promptly furnish written
notice to Seller of such Purchaser Claim or claim. Failure of Purchaser to so
notify Seller within thirty (30) days of the claim being made against Purchaser
shall release Purchaser's rights to indemnity by Seller with respect to such
claim to the extent that such failure materially prejudiced Seller's ability to
defend or settle such claim. Seller shall have fifteen (15) days after receipt
of such notice to undertake, conduct, and control (through counsel of its own
choosing and at its own expense) the settlement or defense thereof, and
Purchaser shall cooperate with Seller in connection therewith. Seller shall
permit Purchaser to participate in such settlement or defense through counsel
chosen by Purchaser (but the fees and expenses of such counsel shall be paid by
Purchaser). So long as Seller, at Seller's cost and expense, (i) have undertaken
the defense of, and assumed full responsibility for all indemnified Losses with
respect to, such claim, (ii) are contesting such claim in good faith, by
appropriate proceedings, and (iii) have taken such action (including the posting
of a bond, deposit, or other security) as may be necessary to prevent any action
to foreclose a lien against or attachment of the property of Purchaser or
Companies for payment of such claim so long as Purchaser shall not be subject to
payment obligations in excess of the limits on Seller's indemnification set
forth under this Agreement, Purchaser shall not pay or settle any such claim.
Notwithstanding compliance by Seller with the preceding sentence, Purchaser may
elect to pay or settle any such claim, but upon such election it shall thereby
automatically, and without any further action by any Party, irrevocably waive
any right to indemnity by Seller with respect to such claim. If within fifteen
(15) days after the receipt of Purchaser's notice of a claim of indemnity
hereunder, Seller do not notify Purchaser that it elects (at Seller's sole cost
and expense) to undertake the defense thereof and assume full responsibility for
all indemnified Losses with respect thereto, or gives such notice and thereafter
fails to contest such claim in good faith or to prevent action to foreclose a
lien against or attachment of Purchaser's or Companies' property or material
harm to Purchaser or the Companies as provided above, Purchaser shall have the
right to contest, settle, or compromise such claim and Purchaser shall not
thereby waive any right to indemnity with respect to such claim under this
Agreement.

                  (h) Any refund of Taxes paid or payable with respect to Taxes
attributable to the Companies shall be promptly paid as follows (or to the
extent payable but not paid due to offset against other Taxes shall be promptly
paid by the Party receiving the benefit of the offset as follows): (i) to Seller
if attributable to Taxes with respect to any Tax year or portion thereof ending
on or before the Closing Date (or for any Tax year beginning before and ending
after the Closing Date to the extent allocable


                                       41


to the portion of such period beginning before and ending on the Closing Date),
including, but not limited to, the potential tax refunds described on Schedule
7.5(h); and (ii) to Purchaser if attributable to Taxes with respect to any Tax
year or portion thereof beginning after the Closing Date (or for any Tax year
beginning before and ending after the Closing Date to the extent allocable to
the portion of such period ending after the Closing Date).

                  (i) In the event that a dispute arises between Seller and
Purchaser as to the amount of Taxes, the Parties shall attempt in good faith to
resolve such dispute, and any amount so agreed upon shall be paid to the
appropriate Party. If such dispute is not resolved within thirty (30) days
thereafter, the Parties shall submit the dispute to the Independent Accounting
Firm for resolution, which resolution shall be final, conclusive and binding on
the Parties. The Independent Accounting Firm shall be instructed to deliver to
the Parties a written resolution of the dispute within twenty (20) Business Days
from the date of its engagement. For purposes of this Section 7.5(i), the
Independent Accounting Firm may determine the issues in dispute following such
procedures, consistent with the provisions of this Agreement, as it deems
appropriate to the circumstances and with reference to the amounts in issue. The
Parties do not intend to impose any particular procedures upon the Independent
Accounting Firm, it being the desire of the Parties that any such disagreement
shall be resolved as expeditiously and inexpensively as reasonably practicable.
The Independent Accounting Firm shall have no liability to the Parties in
connection with such services except for acts of bad faith, willful misconduct
or gross negligence, and the Parties shall provide such indemnities to the
Independent Accounting Firm as it may reasonably request. Notwithstanding
anything in this Agreement to the contrary, the fees and expenses of the
Independent Accounting Firm in resolving the dispute shall be borne equally by
Seller and Purchaser. Any payment required to be made as a result of the
resolution of the dispute by the Independent Accounting Firm shall be made
within ten (10) days after such resolution, together with any interest
determined by the Independent Accounting Firm to be appropriate.

                  (j) Except as provided in Section 9.2(a), Section 9.2(b),
Section 9.7(c), Section 9.8, and Section 9.10, from and after the Closing, the
provisions of this Section 7.5 shall be the exclusive agreement among the
parties (including Seller's indemnities and the Purchaser's indemnities), with
respect to Tax matters, including, but not limited to, indemnification for Tax
matters. In the event of any inconsistency between Section 7.5(g) and Sections
9.4 and 9.5 with respect to Tax matters, Section 7.5(g) shall control.

         SECTION 7.6 Risk of Loss.

                  (a) Between the date hereof and the Closing Date, all risk of
loss or damage to the assets and properties of PGV, including the Plant, shall
be borne by Seller except as set forth in Section 8.3.

                                       42


                  (b) If before the Closing Date all or any portion of the Plant
becomes subject to any condemnation or eminent domain proceeding (the "Condemned
Portion"), Seller shall notify Purchaser promptly in writing of such fact. If
the fair market value of the Condemned Portion is less than twenty-five percent
(25%) of the Initial Purchase Price and the remaining portion of the Plant may
be operated and generate electricity in a manner and amount substantially
similar to that in which the entire Plant was operated immediately prior to the
Effective Date, Seller shall, at its option, either (i) reduce the Initial
Purchase Price by the fair market value of the Condemned Portion (such value to
be determined as of the date immediately prior to such condemnation or eminent
domain proceeding), or (ii) assign to Purchaser at the Closing any claim,
settlement, or proceeds thereof related to such proceeding to which Seller or
any Affiliate of Seller may be entitled. Any failure of a condition to Closing
related to any such proceeding of which Seller shall have so notified Purchaser
shall be deemed not to exist, provided, that Seller exercises its election
pursuant to the preceding sentence within a reasonable period of time. If,
before the Closing Date, all or any portion of the Plant becomes subject to or
is threatened with any condemnation or eminent domain proceeding and the fair
market value of the Condemned Portion is greater than twenty-five percent (25%)
of the Initial Purchase Price, then Purchaser may elect either to (x) require
Seller upon the Closing to assign to Purchaser any claim, settlement, or
proceeds thereof related to such proceeding to which Seller or any Affiliate of
Seller may be entitled and proceed with the Transactions, or (y) terminate this
Agreement.

                  (c) If before the Closing Date all or any portion of the Plant
is damaged or destroyed (the "Damaged Portion") (whether by fire, theft,
vandalism or other casualty) in whole or in part, and the fair market value of
Damaged Portion or the cost of repair of the Damaged Portion is less than
twenty-five percent (25%) of the Initial Purchase Price, and the undamaged
portion of the Plant may be repaired so that the Plant may be operated and
generate electricity in a manner and amount substantially similar to that in
which it was operated immediately prior to the Effective Date, Seller shall, at
its option, either (i) reduce the Initial Purchase Price by the lesser of the
actual cash value of the Damaged Portion (such value to be determined as of the
date immediately prior to such damage or destruction and calculated as the
replacement cost of the Damaged Portion), or the estimated cost to repair or
restore the same, or (ii) bear the costs of repairing or restoring the Damaged
Portion and, at Seller's election, delay the Closing and any right to terminate
this Agreement for a reasonable time necessary to accomplish the same. Any
failure of a condition to Closing related to any such damage or destruction of
which Seller shall have so notified Purchaser shall be deemed not to exist,
provided, that Seller exercises its election pursuant to the preceding sentence
within a reasonable period of time. If the Plant is damaged or destroyed
(whether by fire, theft, vandalism or other casualty) in whole or in part prior
to the Closing and the lesser of the actual cash value of the Damaged Portion
(determined as provided above) or the cost of repair of the Damaged Portion is
greater than twenty-five percent (25%) of the Initial Purchase Price, then
Purchaser may elect either to (x) require Seller upon the Closing to transfer to
Purchaser the proceeds (or the right to the proceeds) of applicable insurance to


                                       43


which Seller or any Affiliate of Seller (other than PGV) may be entitled and
proceed with the Transactions, or (y) terminate this Agreement.

         SECTION 7.7 Insurance. Purchaser shall be obligated at or before
Closing to obtain at its sole cost and effective upon Closing insurance coverage
for the Plant. The proceeds from any Company Insurance Policies (without
reduction for the payment of any deductible related thereto) related to
post-Closing expenses actually paid by Purchaser or the Companies (which shall
exclude any such amounts that were previously accrued by the Companies prior to
the Closing Date and included in the Estimated Adjustment Statement and/or the
Final Adjustment Statement set forth in Sections 3.4 and 3.5) with regard to the
repairs described in Item 1 of Schedule 5.19 (Purchaser shall submit invoices
and other supporting documentation of such expenses to Seller) will be paid by
Seller to Purchaser as soon as practicable after such proceeds are received by
Seller or Seller's Affiliate from the insurance company. Seller and Seller's
Affiliates shall be entitled to retain any additional proceeds they receive
under such Company Insurance Policies with regard to such repairs. For the
avoidance of doubt, Seller or Seller's Affiliate (other than the Companies)
shall bear the cost of any deductible related to the foregoing.

         SECTION 7.8 Announcements. Subject to Section 7.1, prior to the Closing
Date no press release or other public announcement, or public statement or
comment in response to any inquiry, relating to this Agreement or the
Transactions shall be issued or made by Purchaser or Seller without the joint
approval of both Purchaser and Seller; provided, however, that a press release
or other public announcement, regulatory filing, statement or comment made
without such joint approval shall not be in violation of this Section 7.8 if it
is made in order to comply with Applicable Laws or stock exchange rules and in
the reasonable judgment of the Party making such release or announcement, based
upon advice of counsel, prior review and joint approval, despite reasonable
efforts to obtain the same, would prevent dissemination of such release or
announcement in a timely enough fashion to comply with such Applicable Laws or
rules; provided, further, that in all instances prompt notice from one Party to
the other shall be given with respect to any such release, announcement,
statement or comment.

         SECTION 7.9 Post Closing - Further Assurances. At any time or from time
to time after the Closing, each Party will, upon the reasonable request of the
other Party, execute and deliver any further instruments or documents, and
exercise commercially reasonable efforts to take such further actions as may
reasonably be required, to fulfill and implement the terms of this Agreement or
realize the benefits intended to be afforded hereby. After the Closing, and upon
prior reasonable request, each Party shall exercise commercially reasonable
efforts to cooperate with the other, at the requesting Party's expense
(including, but not limited to, out-of-pocket expenses to third parties incurred
by any Party), in furnishing non-confidential and non-privileged Records,
information, testimony and other assistance in connection with any inquiries,
actions, audits, proceedings or disputes involving either of the Parties (other
than in connection with


                                       44


disputes between the Parties) and based upon contracts, arrangements or acts of
Seller or Purchaser, which were in effect or occurred on, prior to, or after
Closing and which relate to PGV or the Plant, including, without limitation,
arranging discussions with (and calling as a witness) officers, directors,
employees, agents, and representatives of Purchaser or Seller. Without limiting
the generality of the foregoing, Seller has provided to Purchaser copies of the
audited financial statements (of the type described in Section 5.17) for PGV for
each of the three full fiscal years prior to Closing and, upon Purchaser's
request, will make the auditors for the Companies reasonably available to answer
clarification questions regarding those financial statements and the financial
statements of the other Companies that the Purchaser may have.

         SECTION 7.10 Post Closing - Information and Records.

                  (a) For a period of five (5) years after the Closing (or, if
requested in writing by Seller within five (5) years after the Closing, until
the closing of any Tax Proceeding with respect to Seller's Tax Returns for all
periods prior to and including the Closing, if later), Purchaser will not
dispose of any books, records, documents, contracts, data or information,
whether in electronic or physical form, and the software and computer hardware
necessary to retrieve such data or information ("Records"), reasonably relating
to the Companies delivered to it by Seller or in the possession of the Companies
as of the Closing without first giving notice to Seller thereof and permitting
Seller to retain or copy such books and records as it may select. During such
period, Purchaser will permit Seller to examine (during normal business hours
and upon reasonable notice) and make copies, at Seller's expense and subject to
such confidentiality restrictions as Purchaser may reasonably impose, of such
Records for any reasonable purpose, including any litigation now pending or
hereafter commenced against Seller or its Affiliates, or the preparation of
income or other Tax Returns.

                  (b) During such five (5) year time period, Purchaser will
provide to Seller, at Seller's expense, copies of such Records reasonably
relating to the Companies delivered to it by Seller or in the possession of the
Companies as of the Closing for any reasonable purpose, including any litigation
now pending or hereafter commenced against Seller or its Affiliates by any
Person (including Purchaser). Seller will provide reasonable notice to Purchaser
of its need to access such Records.

                  (c) If privileged and/or attorney work product documents or
information, including communications between Seller or its Affiliates and any
of their respective counsel, are disclosed to Purchaser in the Records delivered
by Seller or in the possession of the Companies as of the Closing, then
Purchaser agrees that (i) such disclosure is inadvertent, (ii) such disclosure
will not constitute a waiver, in whole or in part, of any privilege or work
product, (iii) such information will constitute confidential information subject
to the provisions of Section 8.4, and (iv) it will promptly return to Seller all
copies of such Records in the possession of the Companies, Purchaser or


                                       45


Purchaser's Affiliates, agents, employees or representatives (including lenders
and financial advisors).

         SECTION 7.11 Use of Seller's Marks. Except as provided in the next
sentence, Purchaser acknowledges and agrees that it does not have and, upon
consummation of the Transactions shall not have, any right, title, interest,
license, or any other right whatsoever to the Seller's Marks. As soon as
practicable and in no event later than thirty (30) days following the Closing
Date, Purchaser shall (a) remove any Seller's Marks from, or cover or conceal
the Seller's Marks on, the assets of the Companies, including signage at the
Plant, and provide written verification thereof to Seller promptly after
completing such removal, and (b) return or destroy (with proof of destruction)
all other assets of the Companies that contain any Seller's Marks that are not
removable or that cannot be permanently covered or concealed, other than in the
case of the Companies' books and records transferred pursuant to this Agreement.
Purchaser agrees never to challenge Seller's (or its Affiliates') ownership of
the Seller's Marks or any application for registration thereof or any
registration thereof or any rights of Seller or its Affiliates therein as a
result, directly or indirectly, of its ownership of the Companies. Purchaser
will not conduct any business or offer any goods or services under any Seller's
Marks. Purchaser will not send, or cause to be sent, any correspondence or other
materials to any Person on any stationery that contains any Seller's Marks or
otherwise operate the Companies in any manner which would or might reasonably be
expected to confuse any Person into believing that Purchaser has any right,
title, interest, or license to use any Seller's Marks.

         SECTION 7.12 Excluded Assets.

                  (a) Notwithstanding anything to the contrary contained in this
Agreement, the Transactions shall exclude the following (the "Excluded Assets"):

                       (i) Except as required in Section 5.22 and Section
7.6(c)(x), all Company Insurance Policies and rights under any Company Insurance
Policies in respect of any and all claims made under such policies whether such
claims are asserted before or after the Closing Date and all rights to any
proceeds payable under any such policy including, without limitation, any
proceeds received by Seller or any of its Affiliates from any Company Insurance
Policies related to Item 1 of Schedule 5.19; and

                       (ii) the Seller's Marks. Seller's representations and
warranties in Articles 4 and 5 shall not apply to any of the items described in
7.12(a)(ii).

                  (b) Prior to the Closing Date, Seller may cause the Companies
to transfer any Excluded Asset to Seller or any of its Affiliates; provided,
however, that any Excluded Asset not so transferred prior to the Closing Date
shall be deemed to have been transferred to Seller without any further action.


                                       46



         SECTION 7.13 Excluded Liabilities. Notwithstanding anything to the
contrary contained in this Agreement, the Transactions shall exclude, and Seller
hereby assumes as of the Closing Date, any liabilities or obligations of the
Companies in respect of the following: (the "Excluded Liabilities"):

                  (a) any Excluded Asset;

                  (b) any Employee Benefit Plan;

                  (c) any Intercompany Arrangements; and

                  (d) any liability to the State of Hawaii for tax credit
refunds received prior to Closing including, without limitation, the tax credit
refunds identified in Schedule 5.15.

         SECTION 7.14 Employees.

                  (a) Purchaser agrees to offer employment to, or cause
Purchaser's Parent to offer employment, commencing as of the Closing Date, to
all of the employees employed at, or whose work responsibilities involve
principally the operation of, the Plant, which employees are listed on Schedule
7.14(a), as amended between the date of this Agreement and the Closing Date to
reflect any changes in the identities of work force personnel, it being
understood that any such change shall not be deemed to be material for purposes
of Section 10.5; provided, however, that such offer shall be subject to each
such employee's satisfaction of reasonable customary hiring requirements of
Purchaser or Purchaser's Parent, as the case may be, which shall be limited to
background checks and post-offer drug screening and the execution of customary
employee agreements regarding confidentiality, inventions and the like, and
shall contain the base salary and incentive compensation and replacement welfare
plans that are set forth on Schedule 7.14(c). Purchaser or Purchaser's Parent
shall continue to provide base salary and incentive compensation at not less
than then the levels set forth on Schedule 7.14(c) for a period of eighteen (18)
months after the Closing Date and shall maintain replacement welfare plans that
are substantially similar when considered in the aggregate to the replacement
welfare plans set forth on Schedule 7.14(c) for a period of eighteen (18) months
after the Closing Date. Each such employee who is offered and accepts employment
with Purchaser or Purchaser's Parent will be referred to herein as a
"Transferred Employee." With regard to the calendar year which includes the
Closing Date, Purchaser shall pay Transferred Employees the amount of any annual
incentive earned and payable under the terms of an annual incentive plan of
Purchaser or Purchaser's Parent that offers incentive compensation in an amount
and terms meeting the standards specified above, prorated based on the portion
of the full calendar year from the Closing Date to December 31, 2004. Purchaser
agrees that it shall also pay the reasonable relocation costs of any Transferred
Employee who shall relocate at Purchaser's or Purchaser's Parent's request
during the period of 18 months after the Closing Date.

                                       47


                  (b) Any individual who is otherwise a Transferred Employee but
who on the day immediately preceding the Closing Date is not actively at work
due to an approved leave of absence due to illness, military leave or disability
shall nevertheless be treated as Transferred Employees but only if he or she is
able to perform the essential functions of his/her job, with or without a
reasonable accommodation, within the period established under COSI PUNA's
applicable leave of absence policy.

                  (c) As of the Closing Date, all Transferred Employees shall
cease to participate in the employee welfare benefit plans (as such term is
defined in Section 3(1) of ERISA) maintained or sponsored by Seller or its
Affiliates and shall commence participation in the then-current employee welfare
benefit plans of Purchaser, Purchaser's Parent or their Affiliates (the
"Replacement Welfare Plans") which are included in the summary of benefit plans
of Purchaser and Purchaser's Parent that are in effect as of the Effective Date
and that are described in Schedule 7.14(c). Subject to the approval of
Purchaser's or Purchaser's Parent's insurers and third party administrators, as
needed (which approval shall be requested by Purchaser or Purchaser's Parent
immediately after the Effective Date), Purchaser or Purchaser's Parent, as
applicable shall (i) waive all limitations as to pre-existing condition
exclusions and waiting periods with respect to the Transferred Employees under
the Replacement Welfare Plans, other than, but only to the extent of,
limitations or waiting periods that were in effect with respect to such
employees under the welfare plans maintained by Seller or its Affiliates and
that have not been satisfied as of the Closing Date, and (ii) provide each
Transferred Employee with credit for any co-payments (if permitted under the
applicable Replacement Welfare Plan) and deductibles paid prior to the Closing
Date during a plan year under Seller's or its Affiliates' plan that has not
ended as of the Closing Date, in satisfying any deductible or out of pocket
requirements under the applicable Replacement Welfare Plans with respect to any
plan year that has not ended as of the Closing Date.

                  (d) Purchaser shall give or cause Purchaser's Parent to give
all Transferred Employees credit for all service recognized by Seller and its
Affiliates immediately prior to the Closing Date under all Replacement Welfare
Plans and arrangements maintained by Purchaser or Purchaser's Parent, as
applicable in which the Transferred Employees become participants. Prior to the
Closing Date, Seller shall provide Purchaser with a description of all such
service recognized by it and its Affiliates, itemized by individual Transferred
Employee. Purchaser agrees that the service credit to be given to Transferred
Employees by Purchaser and its Affiliates is for purposes of eligibility, and
vesting, but not benefit accrual (except for vacation and severance benefits).

                  (e) To the extent allowable by Applicable Law, including,
without limitation, ERISA's fiduciary provisions, and by the tax qualified
401(k) plan sponsored by the Seller or its Affiliates in effect for Transferred
Employees immediately prior to the Closing Date (the "Seller's Savings Plan"),
Purchaser shall take any and all necessary action to cause the trustee of any
tax-qualified 401(k) plan of Purchaser or its Affiliates in




                                       48


which any Transferred Employee becomes a participant to accept a direct
"rollover" in cash (and any outstanding participant loans) of all or a portion
of said employee's "eligible rollover distribution" within the meaning of
Section 402 of the Code from the Seller's Savings Plan if requested to do so by
the Transferred Employee, except in the case where a participant has an
outstanding participant loan which in such case such participant shall
"rollover" all of its "eligible rollover distribution". However, any
tax-qualified 401(k) plan of Purchaser or its Affiliates accepting such a
rollover shall not be required to permit any investment to be made in
Constellation Energy Group, Inc. common stock on behalf of any Transferred
Employee after the Closing Date or to adopt any other provision of Seller's
Savings Plan except to the extent required by Applicable Law.

                  (f) Purchaser shall pay to each Transferred Employee whose
employment is terminated without Cause by Purchaser or one of its Affiliates
within eighteen months after the Closing Date a severance benefit package equal
to:

                o Two weeks of base pay for each full year of service (including
                  service with Purchaser or its Affiliates and service
                  recognized by Seller or Seller's Affiliates immediately prior
                  to Closing).

                o Insurance Benefits: Medical and dental coverage at active
                  employee rates during the period equal to two weeks for each
                  year of service (including service with Purchaser and service
                  recognized by Seller or Seller's Affiliates immediately prior
                  to the Closing); provided, however, that such coverage shall
                  be provided during such period only to the extent that a
                  Transferred Employee timely elects and continues to be
                  eligible for such coverage under COBRA and the terms of the
                  applicable benefit plans then maintained by Purchaser or its
                  Affiliates.

For purposes of calculating the level of severance benefits above to which a
terminated Transferred Employee is entitled, such calculation shall be made as
though the Transferred Employee's termination date is the eighteenth month
anniversary of the Closing Date, regardless of the actual date of termination.
The relocation of a Transferred Employee's employment at Purchaser's or
Purchaser's Parent's request from Purchaser or one of its Affiliates to another
Affiliate of Purchaser shall not constitute termination without Cause for
purposes of this Section.

                  (g) Seller shall notify Purchaser of (i) any increase in the
rate of compensation granted by COSI PUNA or the Companies payable to or to
become payable prior to the Closing Date to any Transferred Employee, and (ii)
any resignations or termination of any Transferred Employees prior to the
Closing Date.

                  (h) Neither Purchaser nor its Affiliates shall have any
liabilities or other obligations with respect to any Transferred Employees or
other former employees




                                       49


or consultants of COSI PUNA or its Affiliates arising from actions or inactions
of COSI PUNA or its Affiliates during periods prior to the Closing Date.

                  (i) Seller and COSI PUNA shall cause the employment of all
Transferred Employees by Seller, COSI PUNA or their Affiliates to be terminated,
and all salaries, wages, benefits, severance payments and benefits or other
amounts due and owing from Seller, COSI PUNA or their Affiliates to the
Transferred Employees as of the Closing Date or as a result of such termination
to be satisfied in full by Seller, COSI PUNA or their Affiliates of Seller,
prior to or concurrently with the Closing.

         SECTION 7.15 Additional Covenants of Purchaser. Purchaser hereby agrees
with and covenants to Seller that prior to consummation of the Transactions or
the termination or expiration of this Agreement pursuant to its terms, unless
Seller shall otherwise consent in writing, Purchaser shall not take any action
which would cause any of Purchaser's representations and warranties set forth in
Article 6 to be false as of the Closing in any material respect.

         SECTION 7.16 Assumption of Obligations. From and after the Closing,
Purchaser shall cause the Companies to fully perform and fulfill all of their
obligations and commitments, whether existing as of the Closing Date or arising
or incurred thereafter.

         SECTION 7.17 Company Guarantees. The Parties shall cooperate and use
commercially reasonable efforts (which shall not include any obligation of
Seller to pay any cost or expense or incur any obligation) in order that,
effective as of the Closing Date, (a) the Company Guarantees identified in Item
3 of Schedule 1.1A and any liabilities related thereto shall be released as to
Seller and its Affiliates, and (b) substitute arrangements, if required, of
Purchaser or its Affiliates shall be in effect.

         SECTION 7.18 Action Taken in connection with the Loan Documents.
Between the Effective Date and the Closing Date, Seller shall take all actions
and binding commitments necessary to irrevocably satisfy in full at the Closing
the Debt Payoff Amount and any other amounts required to satisfy in full the
Loan Documents (including, but not limited to, all fees, penalties, early
termination payments, costs, and the like), terminate all of the Loan Documents
and secure a release from all of the counterparties thereto, finally and forever
releasing the Companies, Seller and its Affiliates under the Loan Documents and
releasing all Encumbrances associated with the Loan Documents (such releases to
be in form and substance reasonably satisfactory to Seller and Purchaser),
including, but not limited to, the Debt Service Reserve Guaranty and the Pledge
Agreement.

         SECTION 7.19 Payment of Intercompany Arrangements. Seller shall cause
all Intercompany Arrangements to be cancelled and terminated, and all amounts
due and owing as of the Closing Date thereunder to be satisfied in full by the
Companies to Seller or any Affiliates of Seller, prior to or concurrently with
the Closing.



                                       50


         SECTION 7.20 Repair of Well KS-11R. Seller, at its expense, shall
repair, or shall cause the Companies to repair, the injection well at the Plant
known as KS-11R in accordance with the repair program identified in Schedule 5.7
(as the same may be modified as provided below) and Applicable Laws and the
requirements of Governmental Authorities having jurisdiction. Any payables or
liabilities of the Companies associated with such repairs that have not been
paid as of Closing shall be accounted for as a Purchase Price adjustment
pursuant to the procedures set forth in Sections 3.4 and 3.5. If such repairs
have not been completed prior to Closing, Seller shall reimburse Purchaser or
the Companies for any costs they reasonably incur after Closing to complete such
repairs in accordance with the repair program identified in Schedule 5.7 (as the
same may be modified as provided below). Purchaser shall have the right to
propose modifications to the repair program identified in Schedule 5.7 which
proposed modifications Seller will consider in good faith, but Seller may
condition acceptance of any such modifications upon, among other things, the
approval of its technical experts, the approval of such modifications by
Governmental Authorities having jurisdiction and Purchaser agreeing to pay any
additional costs and assuming any additional risk associated with implementing
such modifications. If the Parties are unable to reach agreement upon any
modifications proposed by Purchaser, then the repairs shall be conducted by or
for Seller as provided in the first sentence of this Section.

                                   ARTICLE 8

                ACCESS AND CONFIDENTIALITY; TRANSITION PROCEDURES

         SECTION 8.1 General Access. Subject to the provisions of Section 8.2,
during the Transition Period, Seller shall permit (and Seller shall cause the
Companies to permit) Purchaser and its representatives:

                  (a) to have reasonable access, at reasonable times and upon
reasonable advance notice and in a manner so as not to interfere unduly with the
business operations of Seller or the Companies, to the Records of the Companies
relating to their Business and the Plant insofar as the same may be disclosed
without (i) violating any legal constraints or any legal obligation, (ii)
waiving any attorney/client, work product, or like privilege, (iii) disclosing
information about the activities of Seller or its Affiliates (other than the
Companies) that is unrelated to the Companies, their Business or the Plant, or
(iv) disclosing proprietary models of Seller or any of its Affiliates pertaining
to energy project evaluation, energy or natural gas price curves or projections,
or other economic predictive models; and

                  (b) subject to Seller's receipt of any required consent of any
third Person and upon reasonable advance notice to Seller, to conduct at
reasonable times and at Purchaser's sole risk, cost, and expense, in the
presence of representatives of Seller, reasonable inspections of the Plant;
provided, however, that no soil, water, groundwater or other environmental
testing shall be conducted.

                                       51


         SECTION 8.2 Transition Period Procedures. The Parties acknowledge and
agree that in order to ensure that upon Closing the transition of the ownership
of the Purchased Shares and the operation of the Plant is as smooth and orderly
as is reasonably practicable, representatives of Purchaser shall be entitled to
become familiar with the Plant and be introduced to, and have the opportunity to
meet with, suppliers, other vendors and customers of any of the Companies. In
order to facilitate such transitions, not later than five (5) Business Days
following the Effective Date, Seller and Purchaser shall each designate a
representative (each a "Transition Representative") to coordinate the activities
contemplated by this Section 8.2 and shall provide the name and relevant contact
information of their respective Transition Representatives to the other Party.
Either Party may designate a different Transition Representative at any time and
from time to time by written notice to the other Party, which notice shall
specify the name of the relevant individual and his or her contact information.
Within ten (10) Business Days of their selection, the Transition Representatives
shall meet (in person or by telephone) to develop such procedures as such
persons determine to be reasonably necessary or appropriate under the
circumstances to accomplish the transitions contemplated by this Section 8.2;
provided, however, that any such procedures shall be consistent with the other
provisions of this Agreement; and provided, further, that in no event shall any
meetings with suppliers, other vendors or customers of any of the Companies
relating in manner to the Companies, the Transactions, the Plant or the Existing
Contracts be conducted prior to the Closing without Seller's Transition
Representative or other representative of Seller being present, nor shall
Purchaser or any of its Affiliates otherwise contact or communicate directly
with any supplier, other vendor or customer of any of the Companies regarding
the above-described matters prior to the Closing without Seller's prior written
consent, which consent shall not be unreasonably withheld, conditioned or
delayed, unless Seller's Transition Representative or other representative of
Seller shall participate therein.

         SECTION 8.3 Indemnification. Purchaser agrees to indemnify and hold
harmless, release, and defend the Seller's Indemnified Parties and the Companies
from and against any and all Losses arising, in whole or in part, from the acts
or omissions of the Purchaser Indemnified Parties in connection with Purchaser's
inspection or assessment of the Plant and other assets and Records of Seller or
any of the Companies, including claims for personal injuries (including, but not
limited to, injuries to employees of Seller), property damage (including, but
not limited to, property damage to the Plant), and reasonable attorneys' fees
and expenses, and all such inspections and assessments shall be at Purchaser's
sole risk. Nothing in this Article 8 shall be construed to permit Purchaser or
its representatives to have access to any Records of Seller or any of the
Companies relating to the Transactions, including any bids or offers received by
Seller or any of the Companies for the sale of the Purchased Shares or the
Plant, it being agreed that all such bids or offers shall be the sole property
of Seller. The provisions set forth in Sections 9.4, 9.5, 9.6, 9.7(a) and 9.7(b)
shall apply to any indemnification by Purchaser under this Section 8.3. For the
avoidance of doubt, Section 9.7(c) shall not apply to any indemnification by
Purchaser under this Section 8.3.

                                       52


         SECTION 8.4 Confidential Information. Between the Effective Date and
the Closing Date, Purchaser agrees to maintain all information made available to
it under this Agreement confidential and to cause its officers, directors,
agents, employees, representatives, consultants, and advisors to maintain all
information made available to them under this Agreement confidential, all as
provided in the Confidentiality Agreement, the terms of which are incorporated
herein by reference and made a part of this Agreement.

         SECTION 8.5 No Other Contact. Between the Effective Date and the
Closing Date, Purchaser shall not in any way contact or correspond with any
customer, employee, or other Person associated with any of the Companies or the
Seller regarding the Companies, the Plant or the Existing Contracts, without the
prior written consent of Seller.

                                   ARTICLE 9

                           INDEMNIFICATION AND RELEASE

for fraud, willful misconduct, willful misrepresentation, or willful breach of a
representation, warranty, covenant or agreement hereunder, the rights and
remedies of Seller and the Seller's Indemnified Parties, on the one hand, and
Purchaser and the Purchaser Indemnified Parties, on the other hand, for money
damages under this Article are, solely as between Seller and the Seller's
Indemnified Parties on the one hand, and Purchaser and the Purchaser Indemnified
Parties on the other hand, exclusive and in lieu of any and all other rights and
remedies for money damages which each of Seller and the Seller's Indemnified
Parties on the one hand, and Purchaser and the Purchaser Indemnified Parties on
the other hand, may have under this Agreement or under Applicable Laws with

                  (a) Purchaser Claims. Except as otherwise provided in Section

                       (iv) if the Closing occurs, the Excluded Liabilities.

                  (b) Limitations on Seller Indemnification Obligation. As
between the Parties, except in the case of fraud or willful misconduct on the
part of Seller or its Affiliates, the Purchaser Indemnified Parties will not be
entitled to any punitive, incidental, indirect, special or consequential damages
resulting from or arising out of any Purchaser Claims, including damages for
lost revenues, income, or profits, diminution in value of the Plant or any other
damage or loss resulting from the disruption to or loss of operation of the
Plant. The aggregate damages to which the Purchaser Indemnified Parties will be
entitled for all Purchaser Claims shall be limited to ten percent (10%) of the
Initial Purchase Price.

         SECTION 9.3 Indemnification by Purchaser.

                  (a) Seller's Claims. Purchaser will indemnify, defend and hold
harmless Seller and its Affiliates and each of their officers, directors,

"Seller's Indemnified Parties"), from and against any and all Losses which arise
out of or relate to the following (collectively, "Seller's Claims"):

building materials at or adjacent to the Plant or in the soil, surface water,
sediments, groundwater, landfill cells, or in other environmental media at the
Plant; (D) the investigation and/or Remediation of Hazardous Substances that are
present or have been Released before or after the Closing Date at, on, in,
under, adjacent to or migrating from the Plant, including, but not limited to,
Hazardous Substances contained in building materials at the Plant or in the
soil, surface water, sediments, groundwater, landfill cells or in other
environmental media at or adjacent to the Plant; and (E) the investigation
and/or Remediation of Hazardous Substances that are disposed, stored,
transported, discharged, Released, recycled, or the arrangement of such
activities, in connection with the ownership or operation of the Plant, at any
off-site location.

Purchaser acknowledges and agrees that the Losses described in Sections
9.3(a)(iii) and 9.3(a)(iv) shall be retained by PGV and transferred with the
transfer of the Purchased Shares and shall continue to be the responsibility of
PGV and Purchaser.

         SECTION 9.4 Notice of Claim. Subject to the terms of this Agreement and
upon a Party's receipt of notice of the assertion of a claim or of the
commencement of any suit, action or proceeding made or brought by any Person who
is not a Party to this Agreement or an Affiliate of either Party, the Party
seeking indemnification hereunder (the "Indemnitee") will promptly notify the
Party against whom indemnification is sought (the "Indemnitor") in writing of
any damage, claim, loss, liability or expense which the Indemnitee has
determined has given or could give rise to a claim under Section 9.2 or Section
9.3. Such written notice is herein referred to as a "Notice of Claim." A Notice
of Claim will specify, in reasonable detail, the material facts known to the
Indemnitee regarding the claim. Subject to the terms of this Agreement, the
failure to provide (or timely provide) a Notice of Claim will not affect the
Indemnitee's rights to indemnification; provided, however, that the Indemnitor
is not obligated to indemnify the Indemnitee for the increased amount of any
claim which would otherwise have been payable to the extent that the increase
resulted from the Indemnitee's failure to timely deliver a Notice of Claim.

         SECTION 9.5 Defense of Third Party Claims. The Indemnitor will defend,
in good faith and at its expense, any claim or demand set forth in a Notice of
Claim relating to a Third Party Claim and the Indemnitee, at its expense, may
participate in the defense. The Indemnitee may not settle or compromise any
Third Party Claim so long as the



                                       55


Indemnitor is defending it in good faith. If the Indemnitor elects not to
contest a Third Party Claim, the Indemnitee may undertake its defense, and the
Indemnitor will be bound by the result obtained by the Indemnitee. The
Indemnitor may at any time request the Indemnitee to agree to the abandonment of
the contest of the Third Party Claim or to the payment or compromise by the
Indemnitor of the asserted claim or demand. If the Indemnitee does not object in
writing within fifteen (15) days of the Indemnitor's request, then the
Indemnitor may proceed with the action stated in the request. If, within that
fifteen (15) day period, the Indemnitee notifies the Indemnitor in writing that
it has determined that the contest should be continued, the Indemnitor will be
liable under this Article 9 only for an amount up to the amount which the
Indemnitor had proposed as payment or compromise for such Third Party Claim.
This Section 9.5 is subject to the rights of any insurance carrier of Indemnitee
that is defending the Third Party Claim.

         SECTION 9.6 Cooperation. The Party defending the Third Party Claim
will: (a) consult with the other Party throughout the pendency of the Third
Party Claim regarding the investigation, defense, settlement, trial, appeal or
other resolution of the Third Party Claim; and (b) afford the other Party the
opportunity to be associated in the defense of the Third Party Claim. The
Parties will cooperate in the defense of the Third Party Claim. The Indemnitee
will make available to the Indemnitor or its representatives all Records and
other materials reasonably required by them for use in contesting any Third
Party Claim (which Records and other materials shall be subject to the
Confidentiality Agreement). If requested by the Indemnitor, the Indemnitee will
cooperate with the Indemnitor and its counsel in contesting any Third Party
Claim that the Indemnitor elects to contest or, if appropriate, in making any
counterclaim against the Person asserting the claim or demand, or any
cross-complaint against any Person. The Indemnitor will reimburse the Indemnitee
for any expenses incurred by Indemnitee in cooperating with or acting at the
request of the Indemnitor.

         SECTION 9.7 Mitigation and Limitation of Claims. As used in this
Agreement, the term "Indemnifiable Claim" means any Purchaser Claims or Seller's
Claims. Notwithstanding anything to the contrary contained herein:

                  (a) the Indemnitee will take all commercially reasonable steps
to mitigate all losses, damages and the like relating to an Indemnifiable Claim,
including availing itself, to the extent the same are commercially reasonable,
of any defenses, limitations, rights of contribution, claims against third
Persons and other rights at law or equity, and will provide such evidence and
documentation of the nature and extent of the Indemnifiable Claim as may be
reasonably requested by the Indemnitor. The Indemnitee's reasonable steps
include the reasonable expenditure of money to mitigate or otherwise reduce or
eliminate any loss or expense for which indemnification would otherwise be due
under this Article 9, and the Indemnitor will reimburse the Indemnitee for the
Indemnitee's reasonable expenditures in undertaking the mitigation, together
with interest thereon from the date of payment to the date of repayment at the
"prime rate" in effect during such period as published in The Wall Street
Journal;

                                       56


                  (b) any Indemnifiable Claim shall be limited to the amount of
actual out-of-pocket damages sustained by the Indemnitee by reason of such
breach or nonperformance, net of insurance recoveries; provided, that, subject
to the limitations set forth in Sections 9.2(b) and 9.7(c), a Seller Claim for a
breach of this Agreement by Purchaser that results in a termination of this
Agreement or other failure to consummate the Transactions may include any excess
of the Initial Purchase Price over the (i) consideration to be received by
Seller from the sale of the Purchased Shares to a third Person in any subsequent
transaction, or (ii) fair market value of the Purchased Shares if they are not
subsequently sold; and

                  (c) if the Closing occurs, no Party shall have any liability
or obligation to indemnify under Section 9.2(a)(ii) or Section 9.3(a)(ii), as
the case may be, unless the aggregate amount for which such Party would be
liable thereunder, but for this provision, exceeds one million Dollars
($1,000,000), and recovery shall be limited only to such amounts as exceed one
million Dollars ($1,000,000). For purposes of the foregoing, individual claims
of one hundred thousand Dollars ($100,000) or less shall not be aggregated for
purposes of calculating such deductible threshold amount or for calculating
damages in excess of such amount. Nothing in this Section 9.7(c) is intended to
modify or limit a Party's liability or obligation hereunder for other
Indemnifiable Claims. Notwithstanding the foregoing, the limits in this Section
9.7(c) shall not apply to any claims relating to breach of Section 4.5 or
Section 6.6.

         SECTION 9.8 Adjustment to Purchase Price. Any and all payments required
to be made under this Article 9 and Section 7.5 will be treated as an adjustment
to the Purchase Price.

         SECTION 9.9 Specific Performance.

                  (a) Seller acknowledges that the Transactions are unique and
that Purchaser will be irreparably injured should such Transactions not be
consummated in a timely fashion. Consequently, Purchaser will not have an
adequate remedy at law if Seller shall fail to sell the Purchased Shares when
required to do so hereunder. In such event, Purchaser shall have the right, in
addition to any other remedy available in equity or law, to specific performance
of such obligation by Seller, subject to Purchaser's performance of its
obligations hereunder.

                  (b) Purchaser acknowledges that the Transactions are unique
and that Seller will be irreparably injured should such Transactions not be
consummated in a timely fashion. Consequently, Seller will not have an adequate
remedy at law if Purchaser shall fail to purchase the Purchased Shares when
required to do so hereunder. In such event, Seller shall have the right, in
addition to any other remedy available in equity or law, to specific performance
of such obligation by Purchaser, subject to Seller's performance of its
obligations hereunder.



                                       57


         SECTION 9.10 Survival; Time Limitation for Indemnification. The terms
and provisions of this Agreement shall survive the Closing. Notwithstanding the
foregoing, after Closing, any assertion by Purchaser or any Purchaser
Indemnified Party that Seller is liable to Purchaser or any Purchaser
Indemnified Party, or any assertion by Seller or any Seller's Indemnified Party
that Purchaser is liable to Seller or any Seller's Indemnified Party, for
indemnification under the terms of this Agreement or otherwise in connection
with the Transactions must be made in writing and must be given to Seller or
Purchaser, as the case may be (or not at all) on or prior to the date that is
twelve (12) months after the Closing Date, except, in the case of Purchaser, for
matters addressed in Sections 5.23 and 7.5(e), which must be made in writing and
must be given to Seller (or not at all) on or prior to the date that is ninety
(90) days after the date on which the applicable statute of limitations expires
with respect to the matters covered thereby.

         SECTION 9.11 Release. Except for the Excluded Liabilities and Seller's
obligations hereunder including, without limitation, under this Article 9
(including without limitation Seller's obligations under this Article 9 as the
result of the breach of any provision of this Agreement), Purchaser on behalf of
itself and each of its Affiliates, and on behalf of each of its and their
successors and assigns, hereby waives its right to recover from Seller and its
Affiliates and any Person acting on behalf of Seller or any such Affiliates, and
forever releases and discharges Seller, any such Affiliates and any such other
Person, from any and all Losses (including, without limitation, attorneys' fees
and costs), whether direct or indirect, known or unknown, foreseen or
unforeseen, that may arise on account of or in any way be connected with any of
the Companies or the Plant, including without limitation, (a) all liabilities or
obligations under or related to Environmental Laws or relating to any claim in
respect of Recognized Environmental Conditions or Hazardous Substances arising
under Applicable Laws, including Environmental Laws, and (b) all liabilities
that in any way arise out of or are related to or associated with the ownership,
possession, use or operation of any of the assets of any of the Companies,
including the Plant, before or after the Closing. In this regard, Purchaser, on
behalf of itself and each of its Affiliates, and each of its and their
successors and assigns, expressly waives any and all rights and benefits that it
now has or they now have, or in the future may have, conferred upon it or them
by virtue of any statute or common law principle which provides that a general
release does not extend to claims which a party does not know or suspect to
exist in its favor at the time of executing the release, if knowledge of such
claims would have materially affected such party's settlement with the obligor.
Purchaser, on behalf of itself and each of its Affiliates, and each of its and
their successors and assigns, hereby further acknowledges that it is aware that
factual matters now unknown to it or them may have given or may hereafter give
rise to claims, losses and liabilities that are presently unknown, unanticipated
and unsuspected, that the release contained herein has been negotiated and
agreed upon in light of such awareness, and that it nevertheless hereby intends
to be bound and to bind each of its Affiliates, and each of its and their
successors and assigns, to the release set forth above.


                                       58

conditions or restrictions shall be subject to Purchaser's approval to the
extent that such modifications, conditions and restrictions, if any, are not

Agreement pursuant to Section 12.1, such Party shall forthwith provide notice
thereof to the other Party whereupon this Agreement shall terminate and the
Transactions shall be abandoned. Upon any such termination, all filings,
applications and other submissions made pursuant to this Agreement shall, to the
extent practicable, be withdrawn from the respective Governmental Authority by
the Party having filed or submitted the same.

                                   ARTICLE 13

                               GENERAL PROVISIONS

         SECTION 13.1 Expenses. Whether or not the Transactions are consummated,
except as otherwise provided in any other provision of this Agreement, all costs
and expenses (including attorneys' and consultants' fees, costs and expenses)
incurred in connection with this Agreement and the Transactions shall be paid by
the Party incurring such expenses; provided, however, all fees, charges and
costs of economists and other experts, if any, jointly retained by the Parties
in connection with submissions made to any Governmental Authority and advice in
connection therewith respecting approval of the Transactions will be borne by
Purchaser.

         SECTION 13.2 Entire Document; Modification or Amendment. This Agreement
(including the Exhibits and Schedules hereto), and the Confidentiality Agreement
contain the entire agreement between the Parties with respect to the
Transactions, and supersede all negotiations, representations, warranties,
commitments, offers, contracts and writings (except for the Confidentiality
Agreement) prior to the execution date of this Agreement, written or oral. No
modification or amendment of any provision of this Agreement shall be effective
unless made in writing and duly signed by the Parties referring specifically to
this Agreement.

                                       65


         SECTION 13.3 Schedules and Exhibits.

                  (a) The Parties agree and acknowledge that the Schedules in
this Agreement may be incomplete or subject to revision prior to the Closing.
The Parties will cooperate and work in good faith to complete and update such
Schedules in a manner consistent with the provisions of Section 7.2 and the
other requirements of this Agreement. For purposes of determining whether
Purchaser's conditions set forth in Section 10.5 have been fulfilled, the
Schedules shall be deemed to include only the information contained therein on
the Effective Date, and shall be deemed to exclude all information contained in
any update, supplement or amendment thereto to the extent such information
relates to (i) periods prior to the "as of" dates of the Schedules attached to
this Agreement on the Effective Date, or (ii) any conditions or matters that do
not have a Material Adverse Effect; provided, however, that if Closing shall
occur, then all matters disclosed by either Party pursuant to any such update,
supplement or amendment at or prior to the Closing shall be deemed to be matters
of which the other Party had Knowledge.

                  (b) All Schedules and Exhibits hereto which are referred to
herein are hereby made a part hereof and incorporated herein by such reference.
Each Schedule to this Agreement shall be deemed to include and incorporate all
disclosures made on the other Schedules to this Agreement. Certain information
set forth in the Schedules is included solely for informational purposes, is not
an admission of liability with respect to the matters covered by the
information, and may not be required to be disclosed pursuant to this Agreement.
The specification of any dollar amount in the representations and warranties
contained in this Agreement or the inclusion of any specific item in the
Schedules is not intended to imply that such amounts (or higher or lower
amounts) are or are not material, and no Party shall use the fact of the setting
of such amounts or the fact of the inclusion of any such item in the Schedules
in any dispute or controversy between the Parties as to whether any obligation,
item, or matter not described herein or included in a Schedule is or is not
material for purposes of this Agreement.

         SECTION 13.4 Counterparts. This Agreement may be executed in one or
more counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument.

         SECTION 13.5 Severability. Whenever possible, each provision of this
Agreement shall be interpreted in such manner as to be valid, binding and
enforceable under Applicable Laws, but if any provision of this Agreement is
held to be invalid, void (or voidable) or unenforceable under Applicable Laws,
such provision shall be ineffective only to the extent held to be invalid, void
(or voidable) or unenforceable, without affecting the remainder of such
provision or the remaining provisions of this Agreement. Upon such determination
that any term or other provision is invalid, illegal, or incapable of being
enforced, the Parties shall negotiate in good faith to modify this Agreement so
as to effect the original intent of the Parties as closely as possible in an
acceptable manner to



                                       66


the end that the Transactions are fulfilled to the extent possible. To the
extent permitted by Applicable Laws, the Parties waive any provision of
Applicable Law that renders any provision hereof prohibited or unenforceable in
any respect.

         SECTION 13.6 Assignability. The rights under this Agreement shall not
be assignable or transferable nor the duties delegable by any Party without the
prior written consent of the other Parties, which consent may be granted or
withheld in such other Party's sole discretion.

         SECTION 13.7 Captions. The captions of the various Articles, Sections,
Exhibits and Schedules of this Agreement have been inserted only for convenience
of reference and do not modify, explain, enlarge or restrict any of the
provisions of this Agreement.

         SECTION 13.8 Governing Law and Forum. This Agreement and the rights and
obligations of the parties hereunder and the Transactions shall be governed by,
and construed in accordance with, the law of the State of New York without
respect to its conflict of laws provisions. THE PARTIES HERETO AGREE THAT VENUE
IN ANY AND ALL ACTIONS AND PROCEEDINGS RELATED TO THE SUBJECT MATTER OF THIS
AGREEMENT SHALL BE IN THE STATE AND FEDERAL COURTS IN NEW YORK, NEW YORK, WHICH
COURTS SHALL HAVE EXCLUSIVE JURISDICTION FOR SUCH PURPOSE, AND THE PARTIES
HERETO IRREVOCABLY SUBMIT TO THE EXCLUSIVE JURISDICTION OF SUCH COURTS AND
IRREVOCABLY WAIVE THE DEFENSE OF AN INCONVENIENT FORUM TO THE MAINTENANCE OF ANY
SUCH ACTION OR PROCEEDING. SERVICE OF PROCESS MAY BE MADE IN ANY MANNER
RECOGNIZED BY SUCH COURTS. EACH OF THE PARTIES HERETO IRREVOCABLY WAIVES ITS
RIGHT TO A JURY TRIAL WITH RESPECT TO ANY ACTION OR CLAIM ARISING OUT OF ANY
DISPUTE IN CONNECTION WITH THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED
HEREBY.

         SECTION 13.9 Notices. All notices, requests, demands and other

Any Party may from time to time change its address for the purpose of notices to
that Party by a similar notice specifying a new address, but no such change is
effective until it is actually received by the Party sought to be charged with
its contents. Notices which are addressed as provided in this Section 13.9 given
by overnight delivery or mail shall be effective (a) upon delivery, if delivered
personally or by overnight delivery, (b) five (5) days following deposit in the
United States mail, postage prepaid, if delivered by mail, or (c) at such time
as delivery is refused by the addressee upon presentation. Notices which are
addressed as provided in this Section 13.9 given by telefacsimile shall be
effective upon actual receipt if received during the recipient's normal business
hours, or at the beginning of the recipient's next business day after receipt if
not received during the recipient's normal business hours. All notices by
telefacsimile shall be confirmed promptly by the sender after transmission in
writing by certified mail or overnight delivery.

         SECTION 13.10 No Third Party Beneficiaries. Nothing in this Agreement,
whether express or implied, is intended to confer any rights or remedies under
or by reason of this Agreement on any Persons other than the Parties and their
respective permitted successors and assigns, nor is anything in this Agreement
intended to relieve or discharge the obligation or liability of any third
Persons to any Party, nor give any third Persons any right of subrogation or
action against any Party.

         SECTION 13.11 No Relationship. Nothing in this Agreement creates or is
intended to create an association, trust, partnership, joint venture or any
other entity or similar legal relationship between the Parties, or impose a
trust, partnership or fiduciary duty, obligation, or liability on or with
respect to either Party. Neither Party is or shall act as or be the agent or
representative of the other Party.

         SECTION 13.12 Construction of Agreement. This Agreement and any
documents or instruments delivered pursuant hereto shall be construed without
regard to the identity of the Person who drafted the various provisions of the
same. Each and every provision of this Agreement and such other documents and
instruments shall be construed as though the Parties participated equally in the
drafting of the same. Consequently, the Parties acknowledge and agree that any
rule of construction that a document is to be construed against the drafting
party shall not be applicable either to this Agreement or such other documents
and instruments.

         SECTION 13.13 Closing Over Breaches or Unsatisfied Conditions. If
either Party elects to proceed with the Closing with Knowledge by such Party
(evidenced in writing) of any failure of any condition to be satisfied in its
favor or the breach of any



                                       69


representation, warranty or covenant by the other Party, then the condition that
is unsatisfied or the representation, warranty or covenant which is breached at
the Closing Date will be deemed waived by such Party, and such Party shall be
deemed to fully release and forever discharge the other Party on account of any
and all claims, demands or charges, known or unknown, with respect to the same.

         SECTION 13.14 Waiver of Compliance. Except as provided in Section
13.13, to the extent permitted by Applicable Laws, any failure of any of the
Parties to comply with any obligation, covenant, agreement or condition set
forth herein may be waived by the Party entitled to the benefit thereof only by
a written instrument signed by such Party, but any such waiver shall not operate
as a waiver of, or estoppel with respect to, any prior or subsequent failure to
comply therewith. The failure of a Party to this Agreement to assert any of its
rights under this Agreement or otherwise shall not constitute a waiver of such
rights.

         SECTION 13.15 Consents Not Unreasonably Withheld. Wherever the consent
or approval of any Party is required under this Agreement, such consent or
approval shall not be unreasonably withheld, delayed or conditioned unless such
consent or approval is to be given by such Party at the sole or absolute
discretion of such Party or is otherwise similarly qualified.

         SECTION 13.16 Survival.

                  (a) The representations and warranties given or made by any
Party in Articles 4, 5 or 6 hereof or in any certificate or other writing
furnished in connection herewith shall survive the Closing for a period of
twelve (12) months after the Closing Date and shall thereafter terminate and be
of no further force or effect; provided, however, that:

                       (i) all representations and warranties relating to Taxes
and Tax Returns shall survive the Closing (including for purposes of Section
7.5) for ninety (90) days after the date on which the applicable statutes of
limitation (plus any extensions or waivers thereof) expires with respect to the
matter covered thereby; and

                       (ii) any representation or warranty as to which a claim
(including a contingent claim) shall have been asserted during the survival
period shall continue in effect with respect to such claim until such claim
shall have been finally resolved or settled.

Subject to Sections 6.9, 6.10, 6.13 and 13.13, each Party shall be entitled to
rely upon the representations and warranties of the other Party set forth
herein, notwithstanding any investigation or audit conducted before or after the
Closing Date or the decision of any Party to complete the Closing.

                                       70


                  (b) The covenants and agreements of the Parties contained in
this Agreement, including those set forth in Article 9, shall survive the
Closing until performed, unless otherwise specified herein.

         SECTION 13.17 Time of Essence. Time is of the essence in the
performance by the Parties of their obligations under this Agreement. If any
date specified in this Agreement for giving any notice or taking any action is
not a Business Day (or if the period during which any notice is required to be
given or any action taken expires on a date which is not a Business Day), then
the date for giving such notice or taking such action (and the expiration date
of such period during which notice is required to be given or action taken)
shall be the next day which is a Business Day.

         SECTION 13.18 Purchaser's Parent Support. From the date hereof until
the effectiveness of the Closing, Purchaser's Parent agrees to provide Purchaser
any and all financial support necessary to permit Purchaser to perform its
obligations hereunder. After Closing, Purchaser's Parent shall have no
obligation or liability under this Agreement.

                            [SIGNATURE PAGE FOLLOWS]


                                       71





         IN WITNESS WHEREOF, the Parties have executed this Agreement as of the
date first above written.

ORNI 8 LLC
c/o Ormat Nevada, Inc.
980 Greg Street
Sparks, NV 89509

               Re: Purchase and Sale Agreement

Ladies and Gentlemen:

     The undersigned serves as Managing Attorney, Corporate Finance, of
Constellation Energy Group, Inc., and has acted as counsel to Constellation
Power, Inc. (the "Seller") and COSI Puna, Inc. ("COSI PUNA"), in connection with
the transactions contemplated by that certain Purchase and Sale Agreement dated
as of April __, 2004 (the "Agreement"), by and among the Seller, COSI PUNA, ORNI
8 LLC (the "Purchaser") and Ormat Nevada, Inc. (the "Purchaser's Parent").
Capitalized terms used herein and not otherwise defined herein shall have the
meanings assigned to such terms in the Purchase Agreement.

     Our opinions expressed below are specifically subject to the following
limitations, exceptions, qualifications and assumptions:

          (A) Purchaser and Purchaser's Parent have each duly and validly
executed and delivered the Agreement and the obligations set forth therein are
their legal, valid and binding obligations, enforceable against them in
accordance with its terms.

          (B) Each natural person executing the Agreement or any other
instrument, certificate, agreement or document in connection with the
transaction therein described (the "Transaction Documents") is legally competent
to do so.

          (C) There have been no oral or written amendments to the Transaction
Documents, and there has been no waiver of any of the provisions of the
Transaction Documents, by actions or conduct of the parties or otherwise.

          (D) All documents submitted to me as originals are authentic, all
documents submitted to me as certified or photostatic copies conform to the
original document, all signatures on all documents submitted to me for
examination are genuine, and all public records (including all indices thereto)
reviewed by anyone in connection with the transaction described in the Agreement
are accurate, complete and up-to-date.



Page 2

          (E) All certificates submitted to me and each of the representations
and warranties made by the Purchaser in the Transaction Documents are true and
accurate in all material respects.

          (F) I express no opinion as to the enforceability of any provisions
indemnifying a party against, or requiring contributions toward, that party's
liability for its own wrongful or negligent acts, or where indemnification or
contribution is contrary to public policy or prohibited by law.

          (G) My opinions expressed below regarding the enforceability of the
Agreement are qualified by the following:

               (a) such enforceability may be limited by or subject to (i)
bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium, or
other laws and rules of law affecting the enforcement generally of creditors'
rights and remedies, and (ii) the exercise of judicial discretion in accordance
with general principles of equity (regardless of whether such enforceability is
considered in a proceeding in equity or at law); and

               (b) certain provisions of the Purchase Agreement may be
unenforceable in whole or in part. The unenforceability of such provisions will
not render the Purchase Agreement invalid as a whole or substantially interfere
with the realization of the principal benefits provided by the Purchase
Agreement.

          (H) For purposes of my opinion as to the good standings of Seller,
COSI PUNA, CE PUNA I and CE PUNA II in paragraph 1 below, I have relied solely
upon certificates of good standing issued by the State Department of Assessments
and Taxation of Maryland, and nothing has come to my attention leading me to
question the accuracy of such information.

          (I) I am a member of the Bar of the State of Maryland and do not
express any opinions herein on the laws of any jurisdiction other than the laws
of the State of Maryland and the Federal laws of the United States.

     Based on and subject to the foregoing, I am of the opinion that:

     1. Each of Seller and COSI PUNA is a corporation duly organized, validly
existing and in good standing under the laws of the State of Maryland. Each of
CE PUNA I and CE PUNA II is a corporation duly organized, validly existing and
in good standing under the laws of the State of Maryland. Each of CE PUNA I and
CE PUNA II has the requisite power and authority to own, lease and operate its
properties and to carry on its business as it is now being conducted.

     2. Each of Seller and COSI PUNA has all requisite corporate power and
authority to execute and deliver, and to perform its respective obligations
under, the Agreement and to consummate the Transactions.

     3. The execution, delivery, and performance by each of Seller and COSI PUNA
of the Agreement and the consummation of the Transactions have been duly and
validly authorized by all necessary corporate action required on the part of the
Seller and COSI PUNA, and no other corporate proceedings on the part of the
Seller or COSI PUNA are necessary to authorize the Agreement or to consummate
the Transactions. Assuming the due authorization, execution and delivery of the
Agreement by Purchaser and Purchaser's Parent, the Agreement constitutes the
valid and legally binding obligation



Page 3

of the Seller and COSI PUNA, enforceable against the Seller and COSI PUNA in
accordance with its terms, subject to applicable bankruptcy, reorganization,
insolvency, fraudulent transfer, voidable preference, moratorium or similar
laws, and related judicial doctrines, from time to time in effect, affecting or
related to creditors' rights and remedies generally.

     4. Subject to Seller obtaining the Seller's Required Regulatory Approvals
and the Seller's Required Consents, except for compliance with the requirements
of the HSR Act, and except as set forth in the Agreement, the execution and
delivery by Seller and COSI PUNA of the Agreement, the Seller's and COSI PUNA's
compliance with any provision of the Agreement, and the Seller's and COSI PUNA's
consummation of the Transactions will not violate, conflict with, or result in a
breach of any provisions of the articles of incorporation or by-laws of either
Seller or COSI PUNA.

     5. Seller owns beneficially and of record 100% of the CE PUNA I Shares
which constitute all of the issued and outstanding capital stock of, and the
only class of capital stock of, CE PUNA I. Seller owns beneficially and of
record 100% of the CE PUNA II Shares which constitute all of the issued and

RE: STOCK PURCHASE AGREEMENT--PUNA POWER PLANT

Ladies and Gentlemen:

We have acted as special counsel to ORNI 8 LLC, a Delaware limited liability
company (the "Buyer"), in connection with the transactions contemplated by the
Purchase and Sale Agreement dated as of April 22, 2004 (the "Purchase
Agreement") between the Buyer, Ormat Nevada Inc., COSI Puna, Inc. and
Constellation Power, Inc. We render this opinion letter to you at the request of
the Buyer pursuant to Section 11.7 of the Purchase Agreement. Capitalized terms
used and not otherwise defined in this opinion letter have the meanings assigned
to such terms in the Purchase Agreement.

A. DOCUMENTS AND MATTERS EXAMINED

In connection with this opinion letter, we have examined originals, or copies
certified or otherwise identified to our satisfaction, of such documents as we
have deemed relevant or necessary as the basis for the opinions herein
expressed, including the following:

A-l The Purchase Agreement; and

A-2

The documents listed in A-l through A-2 are herein collectively referred to as
the "Documents."

Our opinion is based solely upon a review of the Documents. As to matters of
fact bearing upon the opinions expressed herein, we have, with your consent and
without investigation, relied solely upon and have not independently verified
the accuracy of:

          (a) information in public authority documents;

          (b) information provided in certificates by the Buyer's directors,
     officers and/or employees; and



                    , 2004
--------------------
Page 2


          (c) the representations, warranties and other statements of all
     parties contained in the Documents.

With your consent, we have reviewed no other documents, records, certificates,
or other statements as a basis for the opinions herein expressed. With your
consent, we have not undertaken, nor were we obligated or expected to undertake,
an independent investigation to determine the accuracy of any facts, and any
limited inquiry undertaken by us during the negotiation of the Documents or
preparation of this opinion letter should not be regarded as such an
investigation.

B. ASSUMPTIONS

For purposes of this opinion letter, we have relied, without investigation, upon
the following assumptions:

B-l All natural persons who are involved on behalf of the Buyer have sufficient
legal capacity to enter into and perform the transaction contemplated by the
Documents or to carry out their role in it.

B-2 Each party to the transaction other than the Buyer has satisfied those legal
requirements applicable to it that are necessary to make the Documents signed by
it enforceable against it in accordance with its terms.

B-3 Each party to the transaction other than the Buyer has complied with all
legal requirements pertaining to its status as such status relates to its rights
to enforce the Documents against the Buyer.

B-4 Each document submitted to us for review is accurate and complete, each such
document that is an original is authentic, each such document that is a copy
conforms to an authentic original, and all signatures on each such document are
genuine.

B-5 Each public authority document reviewed by us for the purpose of rendering
this opinion letter is accurate, complete and authentic, and all official public
records (including their proper indexing and filing) are accurate and complete.

B-6 There has been no mutual mistake of fact or misunderstanding, fraud, duress
or undue influence with respect to, or affecting any of, the parties to the
transaction.

B-7 The conduct of the parties to the transaction has complied with any
requirement of good faith, fair dealing and conscionability.

B-8 The party to whom this opinion letter is directed and any agent acting for
it in connection with the transaction have acted in good faith and without
notice of any defense



                    , 2004
--------------------
Page 3


against the enforceability of any rights created by, or adverse claim to any
property or security interest transferred or created as a part of, the
transaction.

B-9 There are no agreements or understandings among the parties, written or
oral, and there is no usage of trade or course of prior dealing among the
parties that would, in either case, define, supplement or qualify the terms of
the Documents.

B-10 Other agreements and court orders will be enforced as written.

B-l1 The Buyer will not in the future take any discretionary action (including a
decision not to act) permitted under the Documents that would result in the
violation of law or constitute a breach or default under any other agreement or
court order.

B-12 The Buyer will obtain all permits and governmental approvals required in
the future, and will take all actions similarly required, relevant to subsequent
consummation of the transaction or performance of the Documents.

B-l3 All parties to the transaction will act in accordance with, and will
refrain from taking any action that is forbidden by, the terms and conditions of
the Documents.

B-14 Each party to the Documents has received sufficient consideration to
support its obligations thereunder.

B-15 The activities of the Buyer are not of such a nature as to cause the
transactions contemplated by the Documents to be governed by laws or regulations
of the State of New York or the United States of America applicable only because
of such activities (such as laws relating specifically to the banking,
securities, insurance or utility industries) and not applicable to business
corporations generally.

C. OPINIONS

Based upon the foregoing examinations and assumptions and subject to the
qualifications and exclusions stated below, we are of the opinion that:

C-l The Buyer is a limited liability company duly organized, validly existing
and in good standing under Delaware law.

C-2 The Buyer has all necessary power and authority to enter into, and to
perform its obligations under the Purchase Agreement and, to the extent material
to the Buyer's performance of its obligations thereunder, to own its properties
and to carry on its business as it is now conducted.



                    , 2004

C-3 The Buyer has authorized, by all necessary action on the part of the Buyer,
the execution and delivery of the Purchase Agreement, and the Buyer has executed
and delivered the Purchase Agreement.

C-4 The Purchase Agreement constitutes the legal, valid and binding obligation
of the Buyer, enforceable against the Buyer in accordance with its terms.

C-5 The execution and delivery by the Buyer of, and the consummation of the
transactions contemplated by, the Purchase Agreement do not (a) violate the
Buyer's Certificate of Formation or Limited Liability Company Agreement

D.   QUALIFICATIONS

The opinions set forth herein are subject to the following qualifications:

D-1 The opinions set forth herein, including those opinions as to the
enforceability of the Documents, are subject to the effect of bankruptcy,
insolvency, reorganization, receivership, moratorium and other similar laws
affecting the rights and remedies of creditors generally and the effect of
general principles of equity, whether applied by a court of law or equity.

D-2 The opinions set forth herein, including those opinions as to the
enforceability of the Documents, are subject to the effect of generally
applicable rules of law that:

     (a) limit or affect the enforceability of provisions of a contract that
purport to require waiver of the obligations of good faith, fair dealing,
diligence and reasonableness;

     (b) provide that forum selection clauses in contracts are not necessarily
binding on the court(s) in the forum selected;

     (c) limit the availability of a remedy under certain circumstances where
another remedy has been elected;

     (d) limit the right of a creditor to use force or cause a breach of the
peace in enforcing rights;

     (e) relate to the sale or disposition of collateral or the requirements of
a commercially reasonable sale;

     (f) limit the enforceability of provisions of releasing, exculpating or
exempting a party from, or requiring indemnification of a party for, liability
for its own action or inaction, to the extent that the action or inaction
involves gross negligence, recklessness, willful misconduct or unlawful conduct;



                    , 2004
--------------------
Page 5


     (g) may, where less than all of a contract may be enforceable, limit the
enforceability of the balance of the contract to circumstances in which the
unenforceable portion is not an essential part of the agreed exchange;

     (h) govern and afford judicial discretion regarding the determination of
damages and entitlement to attorneys' fees and other costs;

     (i) may, in the absence of a waiver or consent, discharge a guarantor to
the extent that (i) action by a creditor impairs the value of collateral
securing guaranteed debt to the detriment of the debtor or (ii) guaranteed debt
is materially modified; and

     (j) may permit a party who has materially failed to render or offer
performance required by the contract to cure that failure unless (i) permitting
a cure would unreasonably hinder the aggrieved party from making substitute
arrangements for performance or (ii) it is important in the circumstances to the
aggrieved party that performance occur by the date stated in the contract.

D-4 Certain provisions in each of the Documents relating to remedies after
breach or default may be unenforceable, but such unenforceability will not,
subject to the other exceptions, qualifications and limitations in this opinion
letter, render the applicable Document invalid as a whole or substantially
interfere with the realization of the principal benefits provided by such
Document, subject to the economic and procedural consequences of any delay
resulting from such unenforceability.

E.   EXCLUSIONS

We express no opinion as to the effect, if any, that one or more of the
following matters may have upon the opinions expressed herein:

                                     PERMITS

1.   PGV believes a casing leak exists in KS-11 at approximately 1850 feet. The
     normal method for avoiding groundwater contamination is to pressurize the
     annular space within the well with nitrogen, which holds the geothermal
     fluid down below a specified depth. If there is no significant leakage in
     the casing, there will be minimal consumption of nitrogen. If there is a
     leak, the fluid can still be held down; however, there will be increased
     consumption of nitrogen. This is the state in which KS-11 is now operating.
     The Underground Injection Control (UIC) permit requires a Mechanical
     Integrity Test (MIT) to be conducted annually, initially scheduled for
     March 2004. PGV held discussions with the appropriate regulators and
     requested, and received, a postponement of the MIT to May 2004 so that PGV
     may have sufficient time to repair the leak prior to such MIT.

     PGV plans to cement the existing 9-5/8" liner permanently into the well. A
     string of 7" hangdown liner will then be suspended in the same manner the
     9-5/8" liner is currently installed. PGV plans to commence work to place
     this liner on May 16, 2004, during a planned outage period. KS-11 is
     expected to be returned to service in June, 2004. The procurement process
     for a larger size diameter (8 1/8") hangdown liner has begun, and this
     larger diameter casing can be made available to install in KS-11 at a
     future date.

2.   PGV has two trailers it uses as offices. No permit or other authorization
     from any Governmental Authority has been obtained related thereto.

                 ABSENCE OF CERTAIN FINANCIAL CHANGES OR EVENTS

1.   On Tuesday 14 January 2004, the Plant experienced a technical failure that
     led to a Plant outage. At approximately 11:00 a.m. PST, a large pentane
     leak was followed by an explosion and fire on one of the Plant's 10 turbine
     generator units (OEC-21). At the time of the incident, Seller believe the
     Hawaiian Electric Company grid was experiencing upsets due to high winds
     (i.e., 70 mph gusts). At the time the fire started, Seller believe a
     disturbance on the grid caused several of the OEC units, non-condensable
     gas compressors, and air compressors to trip off line. Damage to OEC-21 was
     extensive, including the pentane turbine and generator. Approximately 40-
     50% of the Plant's sound barrier wall was blown out by the force of the
     explosion and the Halon system deployed inside the power control shelter.
     There is no apparent major damage to the adjacent unit (OEC-22) or to any
     of the other units in the power block. Three fire monitoring stations were
     immediately directed to spray firewater on adjacent units for cooling as
     well as on OEC-21's vaporizer and the affected area.

     An insurance claim has been filed to recover the costs related to the
     above. The insurance deductible is $500,000. PGV plans to continue repairs
     related to the above.
