ITEM 2. ACQUISITION OR DISPOSITION OF ASSETS

     On March 31, 1998, Calpine Corporation ("Calpine"), a Delaware corporation,
through a wholly-owned  subsidiary,  Calpine Finance Company,  (collectively the
"Company")  entered  into  a  Stock  Purchase  and  Redemption   Agreement  (the
"Agreement") with Dominion Cogen, Inc., a Virginia corporation ("Dominion"), and
Dominion Energy, Inc., a Virginia  corporation  ("DEI").  Under the terms of the
Agreement, the Company acquired the remaining 50 percent of the capital stock of
Texas Cogeneration  Company ("TCC").  TCC is the owner of the 450 megawatt Texas
City and 377  megawatt  Clear  Lake  Power  Plants  located  in  Texas  City and
Pasadena,  Texas. As  consideration  for the purchase of the stock,  the Company
paid to  Dominion  $52.8  million in cash and has  certain  contingent  purchase
payments  beginning  in the year 2000 that  could  approximate  2.9% of  project
revenue.  As part of the  acquisition,  the  Company now also owns a 7.5 percent
interest  in  the  Bayonne  Power  Plant,  a  165  megawatt  natural   gas-fired
cogeneration power plant located in Bayonne, New Jersey.

     Calpine Fuels Texas Corporation,  a wholly-owned subsidiary of Calpine, now
purchases natural gas for the Texas power plants from Enron Capital & Trade Corp
("ECT"). In a related transaction, Calpine Fuels Texas paid approximately $105.3
million to ECT to restructure its existing gas contracts.

     The Company funded the  transactions  with a portion of the net proceeds of
the March 31, 1998 offering of $300.0 million of 7-7/8% Senior Notes Due 2008.

     On June 23, 1997, the Company had previously acquired a 50 percent interest
in TCC for a cash payment of $35.4 million.  In addition,  the Company purchased
from the existing lenders the $155.6 million of outstanding non-recourse project
financing  of the two power  plants,  as  previously  reported in the  Company's
Annual Report on Form 10-K for the year ended December 31, 1997.

     The  Company  now owns a 100  percent  interest in the Texas City and Clear
Lake Power  Plants.  The Company has operated  the plants  since June 1997.  The
Texas City and Clear Lake Power  Plants are  natural  gas-fired,  combined-cycle
cogeneration  facilities.  The plants  provide  electricity  to Texas  Utilities
Electric  Company,  Texas New Mexico Power Company and Houston  Lighting & Power
Company.  As  cogenerators,  they also  provide  electricity  and steam to Union
Carbide  Corporation's  chemical facility and to Celanese Chemical Group, Inc.'s
organic chemicals plant.

and accept from Seller, the Class A Common Stock.

Buyer  for the Class A Common  Stock  shall be an  amount  equal to  Thirty-Five
Million Four  Hundred  Twenty-Five  Thousand  Dollars  ($35,425,000)  (the "Base
Purchase  Price"),  as adjusted  pursuant to Section 2.3 and as Buyer and Seller
may otherwise agree.

         (B) Upon the terms and subject to the conditions of this Agreement,  at
the  Closing,  (i) Seller will deliver to Buyer,  and Buyer will accept,  one or
more stock  certificates  representing all of the Class A Common Stock,  against

obligations  of Seller  and its  Affiliates  under the  agreements  set forth on
Schedule 4.1.10(C)  pursuant to the Omnibus  Assignment and Assumption  Consent,
Novation  and  Amendment  Agreements  in the  form  of  Exhibit  A  hereto  (the
"Assignment  and  Assumption  Agreements"),   and  an  agreement  regarding  the
Stockholders'  Agreement in form and substance satisfactory to Buyer and Seller,
pursuant to which Enron Corp. or Seller will assign, and Calpine  Corporation or
Buyer  will  assume,  all of Enron  Corp.'s  rights  and  obligations  under the

<PAGE>

rights  under  Section  8.1(v)  and  subject  to  obtaining   consents  to  such
assignments from Clear Lake and Cogenron,  respectively, and from the respective
holders of Long Term Debt secured by each of the Facilities,  Seller shall cause
EOC to assign its rights and  interests  as operator  under the Clear Lake O & M
Agreement  and the Texas City O & M Agreement to Calpine  Corporation  or one of
its  Affiliates  designated  by Buyer  pursuant  to  assignment  and  assumption
agreements  in  form  and  substance  satisfactory  to  Seller  and  Buyer.  The
agreements  described  in this  Section  2.2(B)  pursuant  to which  rights  and
obligations are to be assigned and assumed are  collectively  referred to as the
"Assignment Agreements."

2.3  Determination of Purchase Price.  (A) As promptly as practicable  following
the Closing Date, but in any event within 90 days after the Closing Date,  Buyer
shall submit to Seller a proposed  balance  sheet  prepared by the Company as of
the close of business on March 31, 1997 (the "Effective  Date"), for the Company
and the  Subsidiaries,  excluding  all items  relating  to EC5 or Cogen  Venture
(including  (i) all cash  received  by EC5 or from  Cogen  Venture  in the three
months ending March 31, 1997, which is payable to Dominion pursuant to Section 2
of the Amendment to Reorganization Agreement dated as of June 30, 1991, and (ii)
any associated  account  payable to Dominion or its  Affiliates  related to cash
receipts by EC5 or from Cogen Venture which is then  outstanding  (the "Excluded
Assets  and  Liabilities"))  (the  "Proposed  Effective  Date  Balance  Sheet"),
prepared in accordance with generally accepted accounting  principles applied on
a  consistent  basis  ("GAAP")  and  otherwise  on a basis  consistent  with the
December  31  Balance  Sheet  (defined  in  Section  4.1.9(B)),   together  with
appropriate   supporting   calculations  and  documentation  setting  forth,  in
reasonable  detail, the preparation of the balance sheet. If Seller disputes the
correctness of the Proposed  Effective  Date Balance Sheet,  Seller shall notify
Buyer of its  objections in writing within 30 days after receipt of the Proposed
Effective Date Balance Sheet,  which notice shall set forth in reasonable detail
the reasons for  Seller's  objections.  If Seller  fails to deliver  such notice
within such 30-day period,  Seller shall be deemed to have accepted the Proposed
Effective Date Balance Sheet (including Buyer's calculations therein). Buyer and
Seller shall endeavor in good faith to resolve any disputed items within 30 days
after Buyer's receipt of Seller's notice of objections. If they are unable to do
so,  each party  shall have the right to refer the  dispute to Deloitte & Touche
(the "Auditor") for resolution and determination of the Proposed  Effective Date
Balance   Sheet  to  reflect  what  is  required  by  this  Section  2.3.   Such
determination by the Auditor shall be conclusive and binding on the parties. The
fees of the  Auditor  incurred in  resolving  any such  dispute  shall be shared
equally by Seller and Buyer, unless the Auditor determines that, as a whole, the
positions  taken by Buyer in the Proposed  Effective  Date  Balance  Sheet or by
Seller in its  objections  to the Proposed  Effective  Date  Balance  Sheet were
without merit, in which case the party making the unmeritorious  assertion shall
pay the  Auditor's  entire fee. The balance  sheet as of the  Effective  Date as
finally determined pursuant to this Section 2.3 (whether by failure of Seller to
deliver notice of objection,  by agreement of the parties or by determination by
the Auditor) is referred to herein as the "Effective Date Balance Sheet".

         (B) The Purchase  Price shall be calculated  as follows.  To the extent
that Working Capital (defined below) on the Effective Date Balance Sheet exceeds
Working  Capital on the December 31 Balance Sheet (the December 31 Balance Sheet
not being  adjusted  for the items  described on Schedule  4.1.9(C)),  or to the
extent  that the Company or the  Subsidiaries  have made  

                                       16
<PAGE>

unscheduled  principal payments (i.e.,  payments other than those required to be
made  under the  applicable  amortization  schedule)  of Long  Term  Debt  since
December 31, 1996, the Purchase Price shall be increased above the Base Purchase
Price to the extent of  Seller's  Interest  (defined  below) in the  differences
thereof.  To the extent that Working Capital on the Effective Date Balance Sheet
is less than Working  Capital on the December 31 Balance  Sheet (the December 31
Balance Sheet not being adjusted for the items described on Schedule  4.1.9(C)),
the Purchase  Price shall be reduced below the Base Purchase Price to the extent
of Seller's  Interest  in the  differences  thereof.  If the  Purchase  Price is
greater  than the Base  Purchase  Price,  Buyer shall pay Seller the  difference
thereof.  If the Purchase  Price is less than the Base  Purchase  Price,  Seller
shall pay Buyer the  difference  thereof.  All amounts owed for  Purchase  Price
adjustments  pursuant to this Section 2.3 shall be netted as appropriate so that
only one payment  shall be made,  all such  amounts  shall bear  interest at the
Prime Rate from and including the Closing Date through and excluding the date of
payment,  and all  adjustments  shall be made without  duplication.  Any payment
shall be made not later than two Business Days after final  determination of the
Effective  Date  Balance  Sheet  pursuant  to this  Section  2.3 in  immediately
available  funds by wire  transfer  to a bank  account  designated  by the party
entitled to receive the payment.

         (C) For purposes of this Agreement, (i) "Working Capital" means current
assets  (including  without  limitation  cash  and  cash  equivalents,  accounts
receivable,   materials  and  supplies,  and  prepaid  expenses)  minus  current
liabilities  (including  without  limitation  accounts payable and other accrued
current  liabilities,  but  excluding  current  maturities  of long term  debt),
excluding  any items  related to EC5 or Cogen  Venture  (including  the Excluded
Assets and  Liabilities)  and  determined  in  accordance  with  GAAP;  and (ii)
"Seller's  Interest"  means,  with  respect to changes  in Working  Capital  and
unscheduled principal payments of Long Term Debt, 50%.

the failure to have same would not have 

                                       25

of or will reduce Seller's rights under Article VII; provided that, prior to the
Closing,   Buyer  has   disclosed   to  Seller  any   inaccuracy   in   Seller's
representations  and warranties or any errors in or omissions from the schedules

representation  or  warranty,  express  or  implied,  as to the  Company  or the

waiting  period)  and  any  supplemental  information  which  may be  reasonably
requested in connection therewith pursuant to the HSR Act.

         5.2.2 Public  Announcements.  Subject to applicable  securities  law or
stock exchange  requirements,  at all times until the Closing Date,  Buyer shall
promptly   advise,   and  obtain  the  approval   (which  may  not  be  withheld
unreasonably) of, Seller before issuing, or permitting any of Buyer's directors,
officers,  employees, agents or investment bankers, or any of Buyer's Affiliates
to issue, any press release or other announcement with respect to this Agreement
or the transactions contemplated hereby; provided that no further approval shall
be required for press releases or other  announcements  which are  substantially
similar to previously approved releases or announcements provided a copy of such
release or announcement is furnished promptly to Seller.

         5.2.3  Confidential  Information.  In the event that this  Agreement is
terminated or, if not terminated, until the Closing Date, the confidentiality of
any data or information  received by Buyer  regarding the business and assets of
the Company, Seller and their respective Affiliates shall be maintained by Buyer
and its representatives in accordance with the  Confidentiality  Agreement dated
March 10, 1997 executed by Calpine Corporation and Seller (the  "Confidentiality
Agreement").

         5.2.4  Transaction  Costs.  Buyer  shall bear and pay all of the costs,
fees  and  expenses  incurred  by it or on its  behalf  in  connection  with the
transactions contemplated by this Agreement, including the filing fees under the
HSR Act.

         5.2.5  Satisfaction  of Closing  Conditions.  Buyer  shall use its Best
Efforts to cause  satisfaction of the conditions  precedent to Closing set forth
in Sections 6.2.3, 6.2.4, and 6.2.7 through 6.2.9.

         5.2.6 Bank Account and Line of Credit.  Buyer has heretofore  delivered
to Seller a letter from Bank of Nova Scotia (the "Bank")  stating that Buyer (i)
has deposited sufficient funds in a deposit account maintained by it at the Bank
and (ii) has  sufficient  funds  available  to be drawn under the line of credit
provided by the Bank,  to complete  the purchase of the Class A Common Stock and
Long Term Debt as  contemplated  hereby.  Buyer hereby  agrees that prior to the
termination of this Agreement as permitted hereunder,  it shall not (a) withdraw
or use funds  from such  account or (b) draw down on or use funds from such line
of credit  except to purchase  the Class A Common  Stock and the Long Term Debt,
which withdrawal or use in the aggregate would reduce the total amount available
in such  account  and under such line of credit to less than the sum of the Base
Purchase  Price and the amount of the principal and interest  outstanding  under
the Long Term Debt.  From the date hereof through the Closing,  Buyer shall not,
and shall  cause its  Affiliates  not to,  take any action  that would cause the
terms and  conditions  to  utilizing  funds  under such line of credit not to be
satisfied.  Nothing in


                                       31
<PAGE>

this Section 5.2.6 is intended to, nor shall it,  modify  Section 4.2.8 or imply
that Buyer's obligations under this Agreement are subject to financing.

         5.2.7  Certain  FERC  Matters.  At or before the  Closing,  Buyer shall
ratify all written agreements between Clear Lake and Cogenron,  on the one hand,
and Buyer, Seller, DRI or their respective  Affiliates,  on the other, and shall
furnish Seller with a valid  resolution of Buyer  evidencing such  ratification.
Within 30 days after the Closing Date, Buyer shall cause Clear Lake and Cogenron
to file the Self-Certification Notices with FERC.

5.3      Mutual Covenants.  Buyer and Seller covenant and agree as follows:

         5.3.1 Release.  Prior to the Closing,  without limiting Seller's rights
under Sections 6.2.7 through 6.2.9, and 8.1(v), Buyer and Seller shall use their
Best Efforts to have Seller and their  Affiliates  released from all obligations
under the  agreements  listed on Schedule  4.1.10(C)  (including  the agreements
listed   as  Credit   Support   Obligations   therein   (the   "Credit   Support
Obligations")). In addition, Buyer shall provide financial information and offer
to furnish  substantially  equivalent credit support obligations to the obligees
under  the  Credit  Support  Obligations  to effect  such  release  pursuant  to
agreements  that are mutually  satisfactory  to Buyer and Seller.  To the extent
that Seller and its  Affiliates  are not released from all of the Credit Support
Obligations pursuant to agreements reasonably satisfactory to Seller in form and
substance,  Buyer shall indemnify Seller and its Affiliates  pursuant to Section
7.2(B) with respect thereto.

         5.3.2 Tax Returns. Seller, in cooperation with the Company, shall cause
to be prepared and timely filed  (taking into account any  extensions  permitted
hereunder)  each income Tax Return of the Company that includes a taxable period
ending on or before the  Closing  Date which is  required  to be filed after the
Closing Date, and pursuant to Section  9.4(B),  Buyer shall provide  records and
assistance  to enable  Seller to make such  filings.  Seller  shall not cause or
permit  the  Company  to extend the  filing  date for such Tax  Returns  without
Buyer's prior written consent.

         5.3.3  Administrative  Services  Agreement.  Seller  shall cause ECT to
agree (i) to offer to the Company to amend the Administrative Services Agreement
to provide that it will  terminate on a date  designated by the Company which is
not more than 90 days after the Closing Date,  (ii) to continue to perform ECT's
duties and obligations under the  Administrative  Services Agreement through and
including such designated  termination date and (ii) upon such termination date,
to deliver and turn over to the  Company  non-proprietary  software,  electronic
data and books and records relating primarily to the Company or the Subsidiaries
and any other items as are mutually agreed upon by ECT and the Company.

         5.3.4    Employment Matters.

         (A) Facilities  Employees.  Schedule 5.3.4(A) (the "Employee Schedule")
to be attached to this  Agreement  will  contain the names of employees of Enron
International  Payroll,  Inc.  ("EIPI")  who are  engaged in the  operation  and
maintenance  of the  Facilities  (the  "Facilities  Employees"),  their  current
salaries  and work  location.  Seller  shall  deliver the  Employee  Schedule of
Facilities Employees on a confidential basis to the Manager,  Human Resources of
Buyer,  no more than five  business days after this  Agreement is executed.  The
Employee  Schedule shall set forth  substantially  

                                       32
<PAGE>

the same number of employees,  types and numbers of jobs at each Facility and at
the Company,  current  salary  amounts and years of past  service  credit as the
information  previously  provided  to Buyer by  Seller  or its  Affiliates.  The
Employee  Schedule  shall show the name, job position,  work  location,  current
salary and years of past service credit for each of the Facilities Employees. In
addition,  Seller will provide Buyer on a confidential  basis  relevant  written
information   in  Seller's   possession   regarding   each   individual's   work
qualifications,  training  history,  and prior jobs held while  employed  by any
affiliate of Seller.  The average severance cost for these Facilities  Employees
is $25,272 (the "Average  Severance Cost").  Buyer, in its sole discretion,  may
make offers of employment to any of the Facilities Employees.  Buyer understands
that offers of  employment  which are not at least at the current  salary and at
the same  location of any  Facilities  Employee may be declined by such employee
and such  employee,  if  terminated  by EIPI,  would be  entitled to a severance
benefit under the Enron Corp.  Severance Pay Plan (the "Severance Plan"), a copy
of which Seller has provided to Buyer. With respect to Facilities  Employees who
become  entitled to a severance  benefit under the Severance Plan as a result of
Buyer's not having made offers of employment to such  employees at their current
salaries and at the same location,  Seller shall be financially  responsible for
the first nine Facilities  Employees who are paid a severance  benefit under the
Severance Plan, and Buyer shall promptly, without delay, upon receipt of written
notification  by  Seller,  pay to Seller an amount  equal to the  number of such
Facilities  Employees  in excess of nine,  who within 90 days after the Closing,
are paid a severance  benefit under the Severance Plan multiplied by the Average
Severance  Cost.  If any such  Facilities  Employee is  terminated by Seller and
receives  severance  under the  Severance  Plan,  and within 12 months after the
termination of the Facilities Employee by Seller,  Buyer employs such Facilities
Employee,  then Buyer shall  promptly  pay to Seller an amount equal to all or a
portion of the severance  benefit,  if any, paid to such Facilities  Employee by
either  Seller  or  EIPI in  connection  with  such  employee's  termination  of
employment  with either Seller or EIPI,  determined by multiplying the amount of
such  severance  benefit by a fraction,  the numerator of which is the number 12
reduced by the number of full months  that have passed from the Closing  Date to
the employment date, and the denominator of which is the number 12.

         (B) COBRA  Continuation  Coverage.  Seller shall be responsible for the
health care claims of any Facilities Employees that are not employed by Buyer as
of the  Closing  Date who  receive  continuation  of health  care  coverage,  as
required by the Consolidated Omnibus Budget Reconciliation Act of 1985 ("COBRA")
under medical plans by which they are covered.  Buyer shall be  responsible  for
providing health care continuation coverage, if any, as required by COBRA to any
of the Facilities Employees who are employed by Buyer as of or subsequent to the
Closing Date and who cease employment with Buyer for any reason thereafter.

         (C)  Participation  In Buyer's Plans.  Subsequent to the Closing,  upon
employment  with  Buyer,  the  Facilities  Employees  employed by Buyer shall be
eligible for  participation in all employee benefit plans (within the meaning of
Section  3(3) of ERISA)  for which  similarly  situated  employees  of Buyer are
eligible  ("Buyer's  Plans").  Under Buyer's  Plans,  the  Facilities  Employees
employed  by Buyer will be given  credit for Past  Service  (defined  below) for
purposes of determining  (i) eligibility  for  participation  in the retirement,
short or long term disability,  severance and vacation plans (including, without
limitation, eligibility for early retirement), and (ii) the duration 


                                       33
<PAGE>
and amount,  if any, of short or long term  disability  and severance  benefits.
"Past Service" means (i) service as an employee of EIPI or any of its affiliates
and (ii) service as an employee of any other entity, but only to the extent that
such service is recognized  under the applicable and similar plan of EIPI or its
Affiliates, and is continuous through the Closing Date.

         (D)  No  Medical  Preexisting   Condition.   No  preexisting  condition
limitations shall be applicable to Facilities  Employees employed by Buyer under
any  employee  benefit  plan  of  Buyer  provided  that,  with  respect  to each
Facilities  Employee and his or her other covered  dependents,  such  Facilities
Employee and each covered  dependent  enrolls in such plan within 30 days of the
Facilities Employee commencing  employment with Buyer; and further provided that
such  person has been  covered  under a medical  plan for the  six-month  period
preceding  the  Closing.   Additionally,  any  Facilities  Employee  or  covered
dependent  expenses applied toward  deductibles in the year in which the Closing
occurs and any  out-of-pocket  limitations under EIPI's medical and dental plans
in the year in which  the  Closing  occurs  shall be  recognized  under  Buyer's
medical and dental  plans and applied  respectively  toward any  deductibles  or
out-of-pocket limits thereunder in such year.

         (E)  Responsibility  for Claims.  Employee  benefit claims for expenses
incurred  by,  or for  services  provided  to,  Facilities  Employees  or  their
dependents  which occur prior to the date of the Closing  shall be the financial
obligation of Seller.  Employee benefit claims for expenses  incurred by, or for
services  provided to, Facilities  Employees  employed by Buyer or their covered
dependents  which  occur on or after the  Closing  Date shall be  covered  under
Buyer's  Plans.  The  amount and type of  benefits  payable in any case shall be
determined in accordance with the terms of the applicable employee benefit plan.

         (F)  Severance  Benefits.  Buyer shall cause the  Facilities  Employees
employed by Buyer to be eligible for  severance  benefits,  to be paid to such a
Facilities Employee if within one year after the Closing the Facilities Employee
either  has a  reduction  in base  pay and  elects  within  30 days  thereof  to
terminate  employment  or is  terminated  by  Buyer  for  a  reason  other  than
termination  for cause, in the sum of (i) two weeks of base pay for each year of
Past Service and additional  service,  or portion thereof,  credited with Buyer,
and (ii)  two  weeks of base pay for  each  Ten  Thousand  Dollars,  or  portion
thereof,  of annualized base pay, up to a maximum total severance  payment equal
to 52 weeks of base pay. "Termination for cause" as used in this paragraph shall
mean termination for such reasons as Buyer may reasonably determine  constitutes
cause  which is  serious  enough  to result in a  legitimate  business  need for
termination of employment instead of warning,  probation or counseling.  Failure
to meet  established  performance  expectations  shall  not be such a cause  for
termination  unless  the  Facilities  Employee  has  been  counseled  about  the
unacceptable  performance and has had an opportunity to improve  performance for
at least 30 days.


                                   ARTICLE VI

         (B) The  representations  and  warranties in this  Agreement and in any
other  document or certificate  to be delivered at the Closing  pursuant  hereto
shall  survive the  Closing  solely for  purposes of this  Article VII and shall
terminate  540 days  after the  Closing  Date,  except for (i)  Sections  4.1.2,
4.1.5(B),  and 4.2.2,  which,  solely for purposes of this  Article  VII,  shall

Notice specifying the breach of the representation or warranty forming the basis
of such claim has been  delivered  to the party  alleged to have  breached  such
representation or warranty prior to the termination date of such  representation
or warranty as described in this Section  7.1(B).  Any claim for  indemnity  for
breach of covenant herein that pursuant to its terms is to be performed prior to
the Closing shall be effective  only as to matters with respect to which a Claim
Notice has been  delivered  pursuant  hereto  within 180 days after the  Closing
Date. The limited rights  provided to Buyer and Seller  pursuant to this Article
VII and Article VIII shall be the sole remedy for any inaccuracy in or breach of
any  representations,  warranties or covenants contained in this Agreement or in
any document or certificate to be delivered at the Closing. Except to the extent
expressly set forth in Section 4.1 or in any agreement or certificate  delivered
by Seller  or its  Affiliates  at the  Closing,  neither  Seller,  Company,  any
Subsidiary nor any of their respective  Affiliates makes any  representations or
warranties   whatsoever   and  Seller   hereby   disclaims   all  liability  and
responsibility for any other representation,  warranty, statement or information
made or communicated (orally or in writing) to Buyer (including, but not limited
to, any  information  contained in the data room  maintained  by or on behalf of
Seller or any  opinions,  information  or advice which may have been provided to
Buyer by any officer,  stockholder,  director,  employee,  agent,  consultant or
representative  of Seller,  Company,  any Subsidiary or any of their  respective
Affiliates).  Without  limiting  the  generality  of the  foregoing,  except  as
expressly  set forth in Section 4.1 or any  certificates  delivered by Seller or
its Affiliates at the Closing,  neither Seller,  Company, any Subsidiary nor any
of their respective  Affiliates makes any  representation  or warranty as to (i)
title to any of the properties or assets of Company or any Subsidiary,  (ii) the
Facilities,  or (iii) the  prospects  of the  business  of the  Company  and the
Subsidiaries.  SELLER  EXPRESSLY  DISCLAIMS  AND  NEGATES ANY IMPLIED OR EXPRESS
WARRANTY  OF  MERCHANTABILITY,   OR  FITNESS  FOR  PARTICULAR  PURPOSE,  AND  OF
CONFORMITY  TO SAMPLES AND  MODELS.  To the fullest  extent  permitted  by Legal
Requirements,  Buyer and Seller hereby waive any and all rights they may have at
law or in equity  except as set forth in this  Article  VII with  respect to any
inaccuracy in or breach of any  representation  or warranty and covenant in this
Agreement or in any  certificates to be delivered by Seller or its Affiliates at
the Closing.

Section 7.5, Buyer shall  indemnify  Seller  against,  and hold Seller  harmless

representations  and warranties or (ii) covenants made by Buyer herein (any such
Loss being  referred to herein as a "Seller  Indemnified  Loss");  provided that
Buyer shall have no liability  under Section  7.2(A) unless the 

                                       38
<PAGE>

aggregate of all Seller  Indemnified Losses (excluding Seller Indemnified Losses
resulting from a breach of Section 4.2.2, 4.2.8 or 5.2.6) for which Buyer would,
but for this proviso,  be liable exceeds on a cumulative basis  $1,000,000,  and
then only to the extent of any such  excess;  and  further  provided  that Buyer
shall not have any liability  under Section 7.2(A) for any individual item where
the Loss relating to such item is less than $25,000;  and further  provided that
the  aggregate  liability  of  Seller  under  this  Section  7.2(A)  for  Seller
Indemnified  Losses (excluding Seller Indemnified Losses resulting from a breach
of Section  4.2.2,  4.2.8 or 5.2.6)  shall in no event exceed  $10,000,000;  and
further  provided  that the  aggregate  liability of Buyer under this  Agreement
(including Seller  Indemnified Losses resulting from breach of Section 4.2.2) or
in any certificate delivered by Buyer or its Affiliates at the Closing) shall in
no  event  exceed  the  sum of the  Purchase  Price  and the  total  outstanding
principal and interest under the Long Term Debt.

         (B) After the Closing,  Buyer shall  indemnify and hold harmless Seller
and its  Affiliates  from any Losses  arising out of  obligations  to be paid or

thereto is satisfactory in form and substance to Seller.

         (C) Except as expressly set forth in Section 4.2 or in any  certificate
to be delivered by Buyer or its Affiliates at the Closing, neither Buyer nor any
of its Affiliates makes any representations or warranties whatsoever,  and Buyer
hereby disclaims all liability and responsibility for any other  representation,
warranty,  statement or information made or communicated  (orally or in writing)
to  Seller  and  its  Affiliates.  To the  fullest  extent  permitted  by  Legal
Requirements, Seller and its Affiliates hereby waive any and all rights they may
have at law or in equity except as set forth in this Article VII with respect to
any inaccuracy in or breach of any representation,  warranty or covenant in this
Agreement or in any  certificate  to be delivered by Buyer or its  Affiliates at

7.3  Applicability.  SUBJECT TO SECTIONS  7.5 AND 7.6,  THE  PROVISIONS  OF THIS
ARTICLE  VII  SHALL  APPLY   NOTWITHSTANDING   THE  SOLE,  JOINT  OR  CONCURRENT
NEGLIGENCE,  STRICT  LIABILITY OR OTHER FAULT OF THE INDEMNIFIED  PARTY. IF BOTH
THE INDEMNIFIED  PARTY AND THE INDEMNIFYING  PARTY ARE ADJUDICATED  NEGLIGENT OR
OTHERWISE AT FAULT OR STRICTLY LIABLE WITHOUT FAULT, THE CONTRACTUAL OBLIGATIONS
OF INDEMNIFICATION UNDER THIS ARTICLE VII SHALL, SUBJECT TO SECTION 7.5 AND 7.6,
CONTINUE,  BUT THE INDEMNIFYING PARTY SHALL INDEMNIFY THE INDEMNIFIED PARTY ONLY
FOR THE PERCENTAGE OF RESPONSIBILITY  FOR THE DAMAGE OR INJURIES  ADJUDICATED TO
BE ATTRIBUTABLE TO THE INDEMNIFYING PARTY.

        7.4 Indemnification  Procedures.  All claims for  indemnification  under
this Agreement shall be asserted and resolved as follows:

         (A)  A  party  claiming   indemnification   under  this  Agreement  (an
"Indemnified  Party") with respect to any  third-party  claim or claims asserted
against the  Indemnified  Party  ("Third Party Claim") that could give rise to a
right of  indemnification  under this  Agreement  shall  promptly (i) notify the
party from whom  indemnification  is sought  (the  "Indemnifying  Party") of the
Third Party Claim and (ii) transmit to the  Indemnifying  Party a written notice
("Claim Notice")  describing in reasonable  detail the nature of the 

                                       39
<PAGE>

Third Party  Claim,  a copy of all papers  served with respect to such claim (if
any),  the   Indemnified   Party's  best  estimate  of  the  amount  of  damages
attributable to the Third Party Claim and the basis of the  Indemnified  Party's
request for  indemnification  under this  Agreement.  Subject to Section 7.1(B),
failure  to  provide  such  Claim  Notice  shall  not  affect  the  right of the
Indemnified  Party's   indemnification   hereunder  except  to  the  extent  the
Indemnifying  Party is prejudiced  thereby.  Within 30 days after receipt of any
Claim Notice (the "Election  Period"),  the Indemnifying  Party shall notify the
Indemnified  Party (x) whether the  Indemnifying  Party  disputes its  potential
liability to the  Indemnified  Party under this Article VII with respect to such
Third Party Claim and (y) whether the  Indemnifying  Party desires to defend the
Indemnified  Party  against  such  Third  Party  Claim;  provided  that  if  the
Indemnifying  Party fails to so notify the Indemnified Party during the Election
Period,  the Indemnifying  Party shall be deemed to have elected to dispute such
liability.

         (B) If the Indemnifying Party notifies the Indemnified Party within the
Election  Period that the  Indemnifying  Party does not  dispute  its  potential
liability  to the  Indemnified  Party  under  this  Article  VII  and  that  the
Indemnifying  Party elects to assume the defense of the Third Party Claim,  then
the  Indemnifying  Party  shall have the right to  defend,  at its sole cost and
expense,  such  Third  Party  Claim  by  all  appropriate   proceedings,   which
proceedings shall be prosecuted  diligently by the Indemnifying Party to a final
conclusion or settled at the discretion of the Indemnifying  Party in accordance
with this Section 7.4(B). The Indemnifying Party shall have full control of such
defense  and  proceedings,  including  any  compromise  or  settlement  thereof;
provided  that  counsel  selected  by the  Indemnifying  Party  to  defend  such
proceedings shall be reasonably acceptable to the Indemnified Party; and further
provided  that the  Indemnifying  Party  shall  not  enter  into any  settlement
agreement providing for (i) a finding of responsibility or liability on the part
of the Indemnified  Party,  (ii) any material  sanction or material  restriction
upon the conduct of any business, (iii) an affirmative obligation on the part of
the  Indemnified  Party,  other than an  obligation  to pay money  which will be
discharged  in full by the  Indemnifying  Party,  or (iv) any  amendment  to any
contract, agreement, instrument or other document binding on Buyer, the Company,
either Subsidiary,  EC5, or their respective  Affiliates;  in each case, without
the  Indemnified  Party's  consent,  which  consent  shall  not be  unreasonably
withheld.  The  Indemnified  Party is  hereby  authorized,  at the sole cost and
expense of the  Indemnifying  Party (but only if pursuant to Section  7.4(D) the
Indemnified Party is actually entitled to indemnification  hereunder),  to file,
during the Election  Period,  any motion,  answer or other  pleadings  which the
Indemnified  Party shall deem  necessary or appropriate to protect its interests
or those of the Indemnifying Party and not prejudicial to the Indemnifying Party
(it being  understood  and agreed  that if an  Indemnified  Party takes any such
action,  the Indemnifying  Party shall be relieved of its obligations  hereunder
with respect to such Third Party Claim to the extent that such action prejudiced
the Indemnifying Party). If requested by the Indemnifying Party, the Indemnified
Party  agrees,  at the sole  cost and  expense  of the  Indemnifying  Party,  to
cooperate  with the  Indemnifying  Party and its counsel in contesting any Third
Party Claim which the Indemnifying Party elects to contest, including the making
of any related  counterclaim  against the person or entity  asserting  the Third
Party Claim or any cross-complaint against any person or entity. The Indemnified
Party may  participate  in, but not control,  any defense or  settlement  or any
Third Party Claim controlled by the Indemnifying  Party 

                                       40
<PAGE>

pursuant to this Section 7.4, and the Indemnified Party shall bear its own costs
and expenses with respect to such participation.

         (C) If the  Indemnifying  Party fails to notify the  Indemnified  Party
within the  Election  Period that the  Indemnifying  Party  elects to defend the
Indemnified  Party  pursuant to Section  7.4(B),  or if the  Indemnifying  Party
elects to defend the  Indemnified  Party pursuant to Section 7.4(B) but fails to
diligently prosecute or settle the Third Party Claim, then the Indemnified Party
shall have the right to defend, at the sole cost and expense of the Indemnifying
Party (but only if pursuant to Section 7.4(D) the Indemnified  Party is actually
entitled to indemnification hereunder), the Third Party Claim by all appropriate
proceedings,  which proceedings  shall be promptly and vigorously  prosecuted by
the Indemnified  Party to a final conclusion or settled.  The Indemnified  Party
shall have full control of such defense and proceedings; provided, however, that
the  Indemnified  Party may not enter  into,  without the  Indemnifying  Party's
consent,  which shall not be unreasonably withheld, any compromise or settlement
of such Third Party Claim.  The  Indemnifying  Party may participate in, but not
control, any defense or settlement  controlled by the Indemnified Party pursuant
to this Section 7.4(C),  and the Indemnifying Party shall bear its own costs and
expenses with respect to such participation.

         (D) If the  Indemnifying  Party  elects  not to (or is  deemed  to have
elected not to) assume the defense of a Third Party  Claim,  or elects to assume
the defense of a Third Party Claim,  but  reserves the right to dispute  whether
such claim is an indemnifiable loss under this Article VII, the determination of
whether the Indemnified Party is entitled to indemnification  hereunder shall be
resolved by litigation in an appropriate court of competent jurisdiction.

         (E) In the event any Indemnified  Party should have a claim against any
Indemnifying  Party  hereunder  which does not involve a Third Party Claim,  the
Indemnified  Party shall promptly  transmit to the Indemnifying  Party a written
notice (the "Indemnity  Notice")  describing in reasonable  detail the nature of
the  claim,  the  Indemnified  Party's  best  estimate  of the amount of damages
attributable to such claim and the basis of the Indemnified  Party's request for
indemnification under this Agreement.  If the Indemnifying Party does not notify
the  Indemnified  Party within 30 days from its receipt of the Indemnity  Notice
that the Indemnifying Party disputes such claim, the Indemnifying Party shall be
deemed to have disputed such claim. If the  Indemnifying  Party has disputed (or
is deemed to have  disputed)  such  claim,  such  dispute  shall be  resolved by
litigation in an appropriate court of competent jurisdiction.

         (F)  Payments  of all  amounts  owing by the  Indemnifying  Party  with
respect to a Third  Party Claim shall be made within 30 days after the latest of
(i) the  settlement of the Third Party Claim,  (ii) the expiration of the period
for  appeal of a final  adjudication  of such  Third  Party  Claim and (iii) the
expiration of the period for appeal of a final  adjudication of the Indemnifying
Party's liability to the Indemnified Party under this Agreement. Payments of all
amounts owing by the Indemnifying  Party as described in Section 7.3(E) shall be
made within 30 days after the earlier of the expiration of the period for appeal
of a final  adjudication  or agreement  between the  Indemnifying  Party and the
Indemnified  Party as to the Indemnifying  Party's  liability to the Indemnified
Party under this Agreement.

7.5  Limitation  on  Liabilities.  (A) IN NO  EVENT  SHALL  THE  INDEMNIFICATION
OBLIGATIONS UNDER THIS AGREEMENT  (INCLUDING UNDER ARTICLE VII AND ARTICLE VIII)
OR THE  TERM  "LOSSES"  COVER OR  INCLUDE  CONSEQUENTIAL,  INCIDENTAL,  SPECIAL,
INDIRECT,  OR PUNITIVE DAMAGES OR LOST PROFITS  SUFFERED BY THE COMPANY,  BUYER,
SELLER OR  SELLER'S  AFFILIATES,  WHETHER  BASED ON STATUTE,  CONTRACT,  TORT OR
OTHERWISE,  AND WHETHER OR NOT ARISING FROM THE INDEMNIFYING PARTY'S SOLE, JOINT
OR CONCURRENT NEGLIGENCE, STRICT LIABILITY OR OTHER FAULT.

         (B)  Notwithstanding   anything  to  the  contrary  contained  in  this
Agreement, (i) no amounts of indemnity shall be payable as a result of any claim
in  respect  of a Loss under  Articles  VII or VIII to the  extent  that (1) the
Indemnified Party failed to promptly notify the Indemnifying Party of such claim
and the Indemnifying  Party's liability with respect to such claim was adversely
affected  by  such  failure,  or (2)  the  Indemnified  Party  had a  reasonable
opportunity,  but failed,  in good faith to  mitigate  the Loss,  including  the
failure to use Best  Efforts to recover  under a policy of  insurance or under a
contractual right of set-off or indemnity,  (ii) all indemnifiable  Losses under
Articles VII or VIII shall be net of insurance proceeds recovered or recoverable
by the Indemnified  Party and net of tax benefits to the  Indemnified  Party and
its Affiliates,  (iii) in no event shall Seller be responsible for more than 50%
of the amount of Loss suffered or incurred in whole or in part by the Company or
the Subsidiaries (as opposed to a Loss suffered or incurred solely by Buyer; for
example,  a breach of Section  4.1.5(B),  and (iv) the amounts of indemnity  and
Losses  described  in this  Section  7.5  shall in all cases be  subject  to the
restrictions  in Section 7.1, and the provisions of this Section 7.5 shall in no
event expand the  liability of Seller under Section 7.1. The  Indemnified  Party
hereby  waives (or will  cause to be waived)  any  subrogation  rights  that its
insurers may have with respect to any indemnifiable Losses.

7.6  Notification  by Seller of Certain  Matters.  Seller may,  at the  Closing,
notify  Buyer in one or more of the  certificates  to be  delivered  pursuant to
Section 6.1.3, in reasonable detail of any  representation or warranty of Seller
that was not  true and  correct  as of the date of this  Agreement  or as of the
Closing or of any  covenant of Seller that has not been  performed  and complied
with and, if Buyer shall  nevertheless  close under this Agreement,  none of the
matters set forth in such certificate  shall be deemed to be an inaccuracy in or
breach of any of the  representations  and  warranties  or  covenants  of Seller
herein for purposes of, and Buyer shall not be entitled to be  indemnified as to
any of such matters pursuant to, this Article VII.

                                  ARTICLE VIII
                               TERMINATION RIGHTS


        8.1  Termination.  This Agreement may be terminated at any time prior to
the Closing Date as follows, and in no other manner:

         (i)      by mutual consent of Buyer and Seller;

occurred on or before May 15, 1997;

         (iii)    by notice from Buyer to Seller,  if the Closing Date shall not
                  have occurred on or before May 15, 1997;

                                       42
<PAGE>

         (iv)     by  either  party  by  notice  to the  other,  if (a) a  final
                  non-appealable judgment has been entered against such party or
                  any of its  Affiliates  restraining,  prohibiting or declaring
                  illegal  the  transactions  contemplated  hereby  or  (b)  the
                  Company  or  any  of  the  Subsidiaries  shall  have  declared
                  bankruptcy  or  been  involuntarily  put  into  bankruptcy  or
                  receivership; or

        (v)  notwithstanding  Section  5.1.10  or any  other  provision  of this
Agreement,  by notice from Seller to Buyer,  if at any time prior to the Closing
Seller reasonably believes, in its sole discretion,  that the approvals required
(in Seller's  judgment) to enter into this  Agreement or the Assignment of Notes
or to consummate  the  transactions  contemplated  hereby or thereby in a manner
that releases  Seller and its Affiliates from liability under the Credit Support
Obligations  (including  any  approvals  from  Dominion or its  Affiliates,  the
lenders  under  the Long Term  Debt,  and Union  Carbide  Corporation  under the
Guaranty  Agreement,  but  excluding  any  consent of Texas  Utilities  Electric
Company  under the  Surety  Agreement)  will not be  obtained  in a time  period
satisfactory to Seller in its sole discretion.

8.2 Limitation on Right to Terminate;  Effect of Termination.  (A) A party shall
not be allowed to exercise any right of  termination  pursuant to Section 8.1 if
the event  giving  rise to the  termination  right  shall be due to the  willful
failure of such party to perform or observe in any  material  respect any of the
covenants set forth herein to be performed or observed by such party.

         (B) If this  Agreement is  terminated  as permitted  under Section 8.1,
such termination shall be without liability of or to any party to this Agreement
or  any  Affiliate,   shareholder,   director,   officer,   employee,  agent  or
representative  of such party;  provided that  Sections  4.1.19,  4.2.6,  5.1.6,
5.1.7,  5.1.8,  5.2.2,  5.2.3,  5.2.4, 8.2, 9.10 and 9.11 shall survive any such
termination; and further provided that if any such termination under Section 8.1
(excluding Section 8.1(v)) shall result from the willful failure of any party or
its Affiliate to perform a covenant of this  Agreement or from a willful  breach
of this  Agreement by any party or its  Affiliate,  or a breach,  whether or not
willful,  of Section 4.2.8 or 5.2.6 by Buyer, then, subject to Article VII, such
party shall be liable for Losses sustained or incurred by the other parties as a
result of such failure or breach.

                                   ARTICLE IX
                                     GENERAL

9.1 Exclusive  Agreement;  Schedules.  This Agreement and the attached schedules
and exhibits,  the  agreements and documents to be executed  pursuant  hereto or
which are executed concurrently  herewith and the Confidentiality  Agreement set
forth the entire  agreement and  understanding  of the parties in respect of the
transactions   contemplated   hereby  and   supersede   all  prior   agreements,
arrangements and undertakings  (oral or written)  relating to the subject matter
hereof.  The disclosures in the schedules  hereto are to be taken as relating to
the  representations  and  warranties  of Seller as a whole.  The  inclusion  of
information in the schedules  hereto shall not be construed as an admission that
such information is material.  In addition,  matters  reflected in the schedules
are  not  necessarily  limited  to  matters  required  by 

                                       43
<PAGE>

this Agreement to be reflected on such schedules.  Such  additional  matters are
set forth for  information  purposes only and do not  necessarily  include other
matters of a similar nature. No representation, promise, inducement or statement
of intention  has been made by any party which is not embodied in or  superseded
by this  Agreement or the  Confidentiality  Agreement or in the  agreements  and
documents  to be  executed  pursuant  hereto,  and no party shall be bound by or
liable for any alleged  representation,  promise,  inducement  or  statement  of
intention not so set forth.

9.2  Successors  and  Assigns.  All of the  terms,  covenants,  representations,
warranties and conditions of this Agreement  shall be binding upon, and inure to
the benefit of, and be enforceable  by, the parties hereto and their  respective
permitted  successors and assigns (and in the case of indemnities to the benefit
of all  persons  indemnified).  This  Agreement  and the rights and  obligations
hereunder  shall not be assigned  by any party  hereto (by  operation  of law or
otherwise) without the prior written consent of the other party, except that any
party may assign an interest in all of its rights  hereunder  to any  Affiliate;
provided  that no assignment  shall  relieve the  assigning  party of any of its
representations,  warranties,  or obligations  contained herein, and except that
after the Closing  Buyer may  collaterally  assign its rights  hereunder  to the
lenders of the Company, the Subsidiaries, Buyer or its Affiliates, to secure the
Long Term Debt or any extensions or replacements  thereof or any other financing
or refinancing of the Facilities.

9.3 Amendments. This Agreement may be amended, modified, superseded or canceled,
and any of the  terms,  covenants,  representations,  warranties  or  conditions
hereof may be  waived,  only by a written  instrument  executed  by the  parties
hereto,  or,  in the case of a waiver,  by or on  behalf  of the  party  waiving
compliance. The failure of any party at any time or times to require performance
of any provisions  hereof shall in no manner affect the right at a later time to
enforce the same. No waiver by any party of any  condition,  or of any breach of
any term, covenant,  representation or warranty contained in this Agreement,  in
any one or more  instances,  shall be deemed to be or  construed as a further or
continuing  waiver  of any such  condition  or  breach  or a waiver of any other
condition  or of any  breach  of any other  term,  covenant,  representation  or
warranty.

9.4 Records and Access. (A) After the Closing, Seller shall deliver to Buyer all
files and records in its  possession  that are normally  maintained by Seller or
its  Affiliates  in  respect  of  the  Company   (including  all  documents  and
information  contained in the data room maintained by or on behalf of Seller) as
soon as practicable; provided that Seller may make and keep copies of such files
and records.

         (B) From and after the  Closing,  Buyer  shall  maintain  copies of all
books,  records and other information  (including books, records and information
relating  to  financial  information,  taxes  and  litigation)  relating  to the
Facilities  and the  Company and shall not  destroy  any of same  without  first
allowing Seller, at Seller's expense, the opportunity to make copies of same for
a period of not less than five years (or if longer,  the  applicable  statute of
limitations  period).  During  such  period,  Buyer  shall give Seller and their
representatives  reasonable  cooperation,  access and staff  assistance,  during
normal  business hours and upon reasonable  notice,  with respect to such books,
records and  information  as may be  necessary  for general  business  purposes,
including for the  preparation  of tax returns and financial  statements and the
management  and  handling  of tax  audits  and  

                                       44

litigation;  provided that such  requested  cooperation,  access and  assistance
shall not  unreasonably  interfere  with the  normal  operations  of Buyer.  9.5
Further  Assurances.  Each party agrees to execute such further  instruments  or
documents as the other party may from time to time  reasonably  request in order
to  confirm  or  carry  out the  transactions  contemplated  in this  Agreement;
provided that no such instrument or document shall expand a party's  obligations
or liabilities beyond that contemplated in this Agreement.

                                PURCHASE AND SALE

                  2.1  Purchase  and  Sale  of  Stock.  Subject  to  the  terms,
covenants and  conditions  set forth herein,  on the Closing Date,  Seller shall
sell,  assign,  transfer and deliver to Purchaser,  and Purchaser shall purchase

in writing not later than two (2) Business Days prior to the Closing Date.

                  2.3      Additional Dividend.

                  (a) (i)  Seller  and  Purchaser  agree  that if the  Company's
actual  book  net  income  (excluding  income  of or  distributions  from EC5 or
Bayonne), as calculated in accordance with GAAP (except that in calculating such
net income,  no  adjustments  will be made to the actual book net income for the
Company for the period  beginning  January 1, 1998 and ending  March 31, 1998 to
reflect changes in prior period accruals of receivables and liabilities existing
as of  December  31,  1997  which  directly  relate to matters in dispute in the
Company's  current  litigation  with  TNP from the  balances  reported  for such
receivables and liabilities in the unaudited financial statements of the Company
as of December 31, 1997,  a copy of which is 

                                       56
<PAGE>

attached  hereto as  Schedule  2.3A,  other than  billing,  invoicing  and other
administrative adjustments made in the ordinary course of the Company's business
with TNP) (the  "Actual  Book  Earnings")  for the period  from  January 1, 1998
through the Closing Date is greater than the  projected  amount of the Company's
book net  income  as shown on the  Company's  1998  budget  attached  hereto  as
Schedule  2.3B (the  "Projected  Book  Earnings")  for such  period,  Seller and
Purchaser shall take all actions necessary to cause the Company to declare as of
the Closing Date and pay to each of Seller and  Purchaser a cash  dividend  (the
"Additional  Dividend")  to each of  Seller  and  Purchaser  equal to 50% of the
amount by which the Actual Book  Earnings for such period  exceed the  Projected
Book Earnings for such period.

                           (ii)  The Additional Dividends will be calculated and
 paid as follows.

                                    (A)  On or before April 13, 1998, Purchaser 
shall deliver to Seller
Purchaser's  best estimate of the Company's  Actual Book Earnings for the period
from January 1, 1998 through the Closing Date, and the Additional Dividends,  if
any, shall initially be calculated on the basis of such estimate.  The estimated
Additional  Dividends shall be paid to each of Purchaser and Seller on or before
April 20, 1998.

                                    (B)  On or before July 1, 1998, Purchaser 
shall deliver to Seller Purchaser's
final  calculation  of the  Company's  Actual Book  Earnings for the period from
January 1, 1998 through the Closing Date. If Seller  disputes such  calculation,
Seller  shall,  within  seven (7) days after its  receipt  of such  calculation,
deliver to Purchaser a notice of such dispute and a  description  of the reasons
therefor.  If Seller fails to deliver  such notice of dispute  within such seven
(7) day  period,  Seller  shall  be  deemed  to have  consented  to  Purchaser's
calculation,  and the final Additional Dividend shall be computed on that basis.
If the final aggregate amount of the Additional Dividends computed in accordance
with the clause (B) (subject to  resolution of any disputes) is greater than the
aggregate  amount of the estimated  Additional  Dividends  paid to Purchaser and
Seller  pursuant to clause (A) above,  an amount equal to fifty percent (50%) of
such excess shall be paid to each of Purchaser  and Seller on or before July 10,
1998 (or, if the calculation of the Additional Dividends is disputed, within ten
(10) days after the resolution of such dispute).  If the final aggregate  amount
of the Additional  Dividends computed in accordance with the clause (B) (subject
to resolution of any disputes pursuant to Section 2.3(b) below) is less than the
aggregate  amount of the estimated  Additional  Dividends  paid to Purchaser and
Seller  pursuant to clause (A) above,  Purchaser  and Seller shall each repay to
the Company an amount  equal to fifty  percent  (50%) of such  deficiency  on or
before July 10, 1998 (or, if the  calculation  of the  Additional  Dividends  is
disputed, within ten (10) days after the resolution of such dispute).

                  (b) If  Purchaser  and  Seller  are  unable to agree  upon the
amount of the Company's Actual Book Earnings for the period from January 1, 1998
to the Closing  Date by July 10,  1998,  then,  at any time after July 10, 1998,
either Seller or Purchaser may request,  by notice to the other party,  that the
determination   of  Actual  Book  Earnings  for  such  period  be  submitted  to
arbitration  (the  "Arbitration")  before a  mutually  agreeable  and  qualified


                                       57
<PAGE>

partner  of  KPMG  Peat  Marwick  LLC,  or  another  national  certified  public
accounting firm mutually  acceptable to Purchaser and Seller (the "Arbitrator").
The Arbitration shall be decided in accordance with this Agreement, GAAP and the
accounting  practices of the Company. The Arbitration shall be completed by July
31, 1998 (or the earliest later date  reasonably  practicable)  and shall be the
sole and binding  method of  resolving  disputes  between  Purchaser  and Seller
concerning the  calculation of Actual Book Earnings.  Purchaser and Seller shall
each bear their own costs and expenses in connection  with the  Arbitration  and
shall share the fees and costs of the Arbitrator equally; provided, however, the
Arbitrator  shall have the authority to award costs and expenses to either party
and/or to require either party to pay a greater  proportion of the  Arbitrator's
fees and expenses if the Arbitrator determines that the either party pursued the
Arbitration or resisted settlement of the dispute frivolously or arbitrarily.

                  2.4 Excluded Liabilities.  None of Purchaser,  the Company and
its Subsidiaries, or DEI Texas shall, as a result of Purchaser's purchase of the
Purchased Assets,  assume or be obligated to pay, perform or otherwise discharge
the  following   liabilities   or  obligations   (collectively,   the  "Excluded
Liabilities"):

                  (a) any  liabilities or obligations of Seller,  DEI or DRI for
capital  contributions  to the Company,  any  Subsidiaries of the Company or DEI
Texas  relating  to the period up to and ending on the Closing  Date;  provided,
however,  that if either Dominion  Entity or DRI is required,  after the Closing
Date,  to make any  equity  contributions  to the  Company  or its  Subsidiaries
pursuant to the Equity Support Agreements in respect of pre-Closing  obligations
thereunder,  the  Purchase  Price and the  aggregate  amount  of the  Redemption
Payments  shall each be increased by an amount equal to fifty  percent  (50%) of
the amount of any such equity contribution.

                  (b) any  liabilities  for loans or other  Indebtedness  of the
Company,  its Subsidiaries or DEI Texas to any of the Dominion Entities or their
Affiliates,  other than  amounts  due to DEI under the  Administrative  Services
Agreement for services  performed by DEI prior to the Closing Date,  amounts due
to DEI  Texas  under  the DEI  Texas  Gas  Supply  Agreements  for gas  supplied
thereunder by DEI Texas prior to the Closing Date, and liabilities  described in
items 1 and 2 on Schedule 4.7;

                  (c) except for item 1 on Schedule  4.15B,  any  liabilities or

Dominion Entities or their Affiliates under the Reorganization  Agreement or the
Agreement Regarding Stockholders Agreement;

                  (d) any  liabilities  or obligations in respect of Taxes which
are the  Dominion  Entities'  responsibility  under  Section 6.5 or which may be
payable by either of the Dominion  Entities or their  Affiliates with respect to
dividends or distributions to such Persons from the Company or DEI Texas;

                  (e) any liabilities,  obligations or responsibilities relating

<PAGE>

or by any trade or business (whether or not  incorporated)  which is or has ever
been  under  common  control,  or which is or has ever been  treated as a single
employer,  with any of the Dominion  Entities under Section 414(b),  (c), (m) or
(o) of the Code ("ERISA Affiliate") or to which any of the Dominion Entities and
any ERISA Affiliate  contributed  ("ERISA Plans"),  including any  multiemployer

the  performance  of DEI  thereunder,  arising or relating to acts or  omissions
occurring on or before the Closing  Date,  other than  accounts  payable (not to
exceed  $75,000 in the aggregate)  owed to DEI arising out of DEI's  performance
under the Administrative Services Agreement prior to the Closing Date which have
not been paid or reimbursed to DEI as of the Closing Date; and

                  (g) any liabilities, obligations or responsibilities of any of
the  Dominion  Entities  not  related  to or  arising  from the  Company  or its
Subsidiaries, the Bayonne Interest, DEI Texas or the Projects.

                  2.5 Closing.  The closing  ("Closing") for the consummation of
the transactions contemplated by this Agreement, including the purchase and sale
of the Purchased Assets and the Stock Redemption shall take place at the offices
of  Washburn,  Briscoe & McCarthy,  A  Professional  Corporation,  55  Francisco

        2.6  Deliveries  by Dominion  Entities.  At the  Closing,  the  Dominion

                                   ARTICLE III
                               REDEMPTION OF STOCK

                  3.1 Stock  Redemption.  Subject  to the terms,  covenants  and
conditions  set forth herein,  on the Closing Date, the Company shall redeem and
accept from Seller,  and Seller  shall tender and deliver to the Company,  3,677
shares  of the  Class B common  Stock  (the  "Redeemed  TCC  Stock").  Upon 

                                       59
<PAGE>

such redemption,  the Redeemed TCC Stock shall, at the Company's option, be held
by the Company as treasury stock or retired.

                  3.2 Redemption  Payment. In consideration of the redemption of
the Redeemed TCC Stock by the Company,  and subject to the terms,  covenants and
conditions  set forth  herein,  the Company  shall make a monthly  payment  (the
"Redemption  Payment")  to Seller at the end of each  calendar  month during the
Redemption Term equal to the product of (a) the applicable Redemption Percentage
for such month and (b) the Gross Revenues for such month; provided,  however, no
Redemption Payment shall be due (x) in any month in which the Gross Revenues for
the calendar year to date through the end of such month are not greater than the
product of (i)  $30,000,000  times (ii) the number of months  elapsed to date in
such  calendar  year through the month in question  divided by 12, (y) after the
expiration or termination of the Redemption Term, and (z) if Seller breaches its
covenant  set  forth  in  Section  6.1  below;  provided,  further,  that  if no
Redemption Payment is due in any given month as a result of the foregoing clause
(x) and in a subsequent month in such calendar year a Redemption Payment is due,
the  Company  shall  make an  additional  Redemption  Payment  to Seller in such
subsequent month sufficient to cause the sum of all Redemption  Payments made in
such calendar year to date to equal the total amount of Redemption Payments that
would have been paid in such calendar  year had clause (x) not been  applicable;
provided,  further,  that if the Gross  Revenues in any calendar year during the
Redemption  Term are less than  $30,000,000,  the Company shall be entitled to a
credit against  Redemption  Payments  otherwise  required to be paid in the next
subsequent  year in which  Redemption  Payments  are payable  equal to the total
amount of Redemption  Payments made in the calendar year in which Gross Revenues
were less than $30,000,000.

                  3.3      Redemption Term.

                  (a)  Notwithstanding  anything  herein  to the  contrary,  the
Redemption Term shall terminate, and no further Redemption Payments shall be due
or payable, on the last day of the calendar month in which the Net Present Value
of all Redemption Payments and all Substitute Redemption Payments made to Seller
through the end of such month,  together with any payments of liquidated damages
under Section 3.5, equals or exceeds $56,750,000.

                  (b) Notwithstanding anything herein to the contrary, if at the
end of the then current Redemption Term, the Net Present Value of all Redemption
Payments and all Substitute  Redemption  Payments made to Seller through the end
of the  last  month  of  such  Redemption  Term is less  than  $56,750,000,  the
Redemption Term shall be automatically  extended for an additional five (5) year
period,  subject  to  termination  at such time as the  requirements  of Section
3.3(a) are satisfied;  provided,  however,  that the Redemption Term shall in no
event be extended beyond December 31, 2032.

                  3.4 Substitute  Redemption  Payment. In the event that, at the
end of any calendar year during the Redemption Term, except the calendar year in
which the  Redemption  Term  terminates  pursuant to Section  3.3(a),  the total
amount of electric energy actually  produced by the Projects in the aggregate is
less than the Minimum  Generation  Level,  the Company  shall make an 

                                       60
<PAGE>

additional payment (the "Substitute  Redemption Payment") to Seller equal to the
product  of (i) the  Generation  Shortfall  Amount,  times  (ii) the  applicable
Redemption  Percentage for such calendar year,  times (iii) the Weighted Average
Market  Electricity  Price for such calendar  year. A simplified  example of the
calculation of the Substitute Redemption Payment is attached as Schedule 3.4 for
purposes of illustration only. In practice, actual calculations will be done for
each Project on an hourly basis.

                  3.5 Liquidated  Damages. In the event of (i) the occurrence of
a Bankruptcy  Event with  respect to the Company,  (ii) a failure by the Company
and Calpine to pay the  Substitute  Redemption  Payment to Seller  within twenty
(20) days after such amount was finally  determined  to be due,  (iii) a sale by
the Company (or an  Affiliate of the Company to whom the  Company's  interest in
the Projects may have been  transferred) of either of the Projects except a sale
or transfer of either  Project to Calpine or one of its  Affiliates or a sale or
transfer of either Project in connection  with the financing of such  Project(s)
through a Capitalized Lease, so long as after such sale or transfer,  Calpine or
its Affiliate  continues to operate,  maintain and control the operation of such
Project(s),  (iv) the sale by Purchaser  (or any  Affiliate of Purchaser to whom
Purchaser's  ownership  of the Company may have been  transferred)  of more than
fifty percent (50%), individually or in the aggregate, of its ownership interest
in the Company to any Person other than Calpine or an Affiliate of Calpine,  (v)
the  sale by  Purchaser  (or any  Affiliate  of  Purchaser  to whom  Purchaser's
ownership of the Company may have been  transferred)  of fifty  percent (50%) or
less of its  ownership  interest in the Company to any Person other than Calpine
or an  Affiliate  of Calpine  in  connection  with  which  Calpine or one of its
Affiliates  ceases  to  operate,  maintain  and  control  the  operation  of the
Projects,  or (vi) the  occurrence  of an Event of  Default  under any  material
Indebtedness  of the Company or its  Affiliates or any Related  Indebtedness  of
Calpine or its Affiliates  which would entitle,  in either such case, the holder
of  such  Indebtedness  or  Related  Indebtedness  to  accelerate  any  material
Indebtedness  of the  Company or the  Partnerships  or secured by either or both
Projects  or to  enforce  a lien  on or  security  interest  in  either  or both
Projects,  Seller shall be entitled to recover, as liquidated damages and not as
a penalty,  an amount equal to the lesser of (a) an amount which, as of the date
such liquidated  damages are paid, would have a Net Present Value of $56,750,000
and (b) the amount  which,  together with all previous  Redemption  Payments and
Substitute  Redemption  Payments,  would be sufficient to cause a termination of
the  Redemption  Term pursuant to Section  3.3(a).  For purposes of this Section
3.5, "material"  Indebtedness means Indebtedness having an outstanding principal
amount  of  $1,000,000  or  more or  which  would  entitle  the  holder  of such
Indebtedness  to exercise a lien on or a security  interest in either Project or
any material part thereof.

                  3.6      Reporting and Payment.

                  (a) Within  thirty  (30) days  after the end of each  calendar
month during the  Redemption  Term, the Company shall deliver to Seller a report
showing the amount of electric  energy  generated  by the  Projects  during such
month,  the  amount  of Gross  Revenues  for such  month  and the  amount of any
Redemption Payment due with respect to such month. Within thirty (30) days after
the end of each  calendar  year during the  Redemption  Term except the 

                                       61
<PAGE>

calendar  year in which the  Redemption  Term  terminates  pursuant  to  Section
3.3(a),  in  addition  to the  report  required  for the last month of such year
pursuant to the preceding sentence, the Company shall deliver to Seller a report
showing the amount of electric  energy  generated  by the  Projects  during such
calendar  year,  the Minimum  Generation  Level for such calendar  year, and the
amount of any  Substitute  Redemption  Payment due with respect to such calendar
year. All such reports shall be accompanied by sufficient backup information and
worksheets to provide Seller a reasonable basis for  understanding and verifying
them,  including,  if requested by Seller,  copies of the invoices sent by Clear
Lake and Texas City to their respective  power  purchasers  (redacted to exclude
any  proprietary or  confidential  information,  but showing at least the amount
billed by Clear Lake or Texas City to such power  purchasers)  and copies of the
receipts log or similar records for Clear Lake and Texas City showing the amount
received from such power purchasers.

                  (b) Seller shall have the right,  during normal business hours
and upon reasonable advance notice to Purchaser and at its own expense, to audit
the invoices, receipts logs and operational logs (showing hours of operation) of
Clear  Lake and Texas  City to verify  the  amount of  Redemption  Payments  due
hereunder. In connection therewith, the Company, Clear Lake and Texas City shall
make such records  available to Seller and its  employees,  representatives  and
agents engaged to perform such audit;  provided,  however,  that any information
reviewed by or disclosed to Seller and its employees, representatives and agents
in connection with such audit shall be held in strictest  confidence,  shall not
be disclosed to any other Person  except as required by law or court order,  and
shall not under any circumstances be used by Seller or any of its Affiliates for
any other purposes whatsoever,  including businesses of Seller or its Affiliates
which are competitive with Clear Lake, Texas City or any of their Affiliates.

                  (c) Any dispute between Seller and the Company  concerning the
calculation of the amount of Redemption Payments under Sections 3.2 or 3.4 shall
be settled by Arbitration  before the Arbitrator.  Such Arbitration shall be the
sole and binding  method of  resolving  disputes  between  Purchaser  and Seller
concerning  the  calculation  of the mount of  Redemption  Payments  due Seller.
Purchaser  and Seller shall each bear their own costs and expenses in connection
with the  Arbitration  and  shall  share  the fees and  costs of the  Arbitrator
equally;  provided,  however,  the Arbitrator  shall have the authority to award
costs and  expenses  to either  party  and/or to require  either  party to pay a
greater  proportion  of the  Arbitrator's  fees and  expenses if the  Arbitrator
determines that the either party pursued the Arbitration or resisted  settlement
of the dispute frivolously or arbitrarily.

                  (d)  All  payments  of  Redemption   Payments  and  Substitute
Redemption  Payments  shall be due within  thirty (30) days after the end of the
calendar  month or  calendar  year,  as  applicable,  to which  such  Redemption
Payments or Substitute  Redemption  Payments relate.  Payments not made when due
shall accrue  interest at an annual rate equal to the "prime rate"  published in
the Wall Street Journal from time to time plus two percent (2%).

                  3.7 Calpine  Guaranty.  Calpine  shall  guarantee  the due and
punctual  payment by the  Company of the  Redemption  Payments,  the  Substitute
Redemption Payments and the liquidated damages set forth in Section 3.5

attached hereto.

                  3.8 Contract Parties.  In furtherance of the obligation of the
Company to make the Redemption  Payments,  Purchaser and the Company agree that,
during the Redemption Term, any and all contracts providing for the provision of
electric  energy or capacity or steam by either Project shall be entered into by
Clear  Lake or Texas  City,  as the case may be,  and shall  not be  contractual
obligations of the Company, Purchaser or any of their respective shareholders or
Affiliates.  If any contracts  providing for the provision of electric energy or
capacity or steam by either  Project are entered into by the Company,  Purchaser
or any of their  respective  shareholders  or  Affiliates  in  violation  of the
foregoing covenant, rather than by Clear Lake or Texas City, as the case may be,
the gross revenues  received pursuant to such contracts shall be included in the
Gross Revenues for purposes of calculating Redemption Payments hereunder.

                  (a)  Each  of  the  Dominion  Entities  and  DEI  Texas  is  a
corporation duly organized, validly existing and in good standing under the laws

duly  qualified  or licensed to do business as a foreign  corporation  and is in
good  standing in each  jurisdiction  in which such  qualification  is necessary
because of the property owned, leased or operated by it or because of the nature
of its business as now being conducted,  except in those jurisdictions where the
failure to be so  qualified  or  licensed  would not  create a Material  Adverse

its obligations hereunder. DEI Texas does not have any Subsidiaries.

                  (b) To the Dominion  Entities' actual knowledge,  Bayonne is a
general partnership duly organized,  validly existing and in good standing under
the  laws of the  State  of New  Jersey.  Seller  has  previously  delivered  to
Purchaser  such  copies  of the  joint  venture  agreement  of  Bayonne  and all

Entities  has full  corporate  power and  authority  to execute and deliver this

neither the execution and delivery of this  Agreement,  nor the  consummation of

breach of or require any consent or approval under the Charter  Documents of any
Dominion Entity,  DEI Texas or EC5, (ii) conflict with or result in a default or
require any consent or approval  under any of the  provisions  of any  contract,
agreement or other instrument to which any Dominion Entity, DEI Texas or, to the

execution,  delivery and performance by the Dominion  Entities of this Agreement
or the consummation of the transactions contemplated hereby.

                  4.4      Title to Purchased Assets and Redeemed TCC Stock.

                  (a) Seller is the lawful owner, of record and beneficially, of

been duly  authorized and validly  issued and are fully paid and  nonassessable.
Seller has good and marketable title to the Class B Common Stock, free and clear
of all Liens,  Claims and Third  Party  Rights,  and with no  restriction  on or
agreement  relating to the voting  rights and the other  incidents of record and
beneficial  ownership  of such Class B Common  Stock  except as  provided in the
Stockholders  Agreement.  At the  Closing,  Seller will  transfer  such good and
marketable  title to the  Purchased  TCC Stock to Purchaser  and will tender the
Redeemed  TCC Stock to the  Company,  in each case free and clear of all  Liens,
Claims and Third Party Rights and with no restriction  on or agreement  relating

beneficial ownership.


                  4.5 Bayonne  Partnership  Interest.  EC5 owns a 7.06%  general
partnership  interest  in Bayonne  (the  "Bayonne  Interest").  To the  Dominion
Entities' actual knowledge,  the Bayonne Partnership  Agreement is in full force

Dominion  Entities  or their  Affiliates  have been  notified by Bayonne (or the
managing  general partner thereof) are required to be made have been made by EC5
or one of the  Dominion  Entities to Bayonne on or before the Closing  Date.  No

acquire,  directly or indirectly,  the Bayonne Interest.  No Dominion Entity has
entered into any, and to the Dominion  Entities'  actual knowledge there are no,

Person acting on behalf of any of the Dominion Entities or under their authority
is or will be entitled to any broker's or finder's  fee or any other  commission
or  similar  fee  directly  or  indirectly  from any of the  parties  hereto  in
connection with any of the transactions contemplated hereby.

                  4.7 Financial  Information.  Seller has delivered to Purchaser
the balance  sheets and income  statements of DEI Texas as of December 31, 1997,
certified as true and correct by the chief  financial  officer of DEI Texas (the
"DEI Texas Financial  Statements") and such copies of the audited balance sheets
and income  statements  of Bayonne as of December  31, 1996 as Seller has in its
possession  (the  "Bayonne  Financial  Statements").  The  DEI  Texas  Financial
Statements  present fairly,  as of December 31, 1997, the financial  position of
DEI Texas in conformity with GAAP. To the Dominion  Entities' actual  knowledge,
the Bayonne Financial Statements are the most recent statements of the financial
condition and results of  operations of Bayonne that EC5, the Dominion  Entities
or their  Affiliates have in their  possession.  Except as set forth on Schedule
4.7, DEI Texas does not have any  liabilities in excess of $25,000 which are not
reflected on the DEI Texas Financial  Statements.  Except for any unpaid amounts
due to DEI for  services  performed  by DEI  under the  Administrative  Services
Agreement  prior to the Closing  Date (which do not exceed  $75,000) and amounts
due to DEI Texas  under the DEI Texas Gas  Supply  Agreements  for gas  supplied
thereunder  by DEI  Texas  prior  to  the  Closing  Date  (which  do not  exceed
$20,000,000),  none of the 

                                       65
<PAGE>

Company,  the  Company's  Subsidiaries  or DEI  Texas  have any  obligations  or
liabilities,  including any Indebtedness, to any of the Dominion Entities or any
of their Affiliates which will survive the Closing Date.

                  4.8 Absence of Changes.  Except as set forth on Schedule  4.8,
since December 31, 1997,  DEI Texas has been operated in the ordinary  course of
business and there has not been:

                  (a) any obligation or liability  (whether  absolute,  accrued,
contingent or otherwise, and whether due or to become due) incurred by DEI Texas
other than current  obligations and liabilities  incurred in the ordinary course
of business not exceeding $25,000 in the aggregate;

                  (b) except for  dividends  referred  to in Section  6.11,  any
declaration, setting aside or payment of any dividend or other distribution with
respect to the DEI Texas Stock, any direct or indirect  redemption,  purchase or
other  acquisition  of any of the DEI Texas Stock or any split,  subdivision  or
reclassification of the DEI Texas Stock;

        (c)  any  sale,  assignment  pledge,  encumbrance,   transfer  or  other
disposition of any material asset of DEI Texas;

        (d) any material damage,  destruction or loss (whether or not covered by
insurance) affecting any material asset or property of DEI Texas;

                  (e) any change in the independent  accountants of DEI Texas or
in the accounting  methods or practices  followed by DEI Texas, or any change in
depreciation or amortization policies or rates followed by DEI Texas;

        (f) any liquidation,  winding up, merger or consolidation  involving DEI
Texas or, to the Dominion Entities' actual knowledge, Bayonne;

        (g) any incurrence of new or additional  indebtedness on the part of DEI
Texas; or

        (h) any  agreement,  whether in writing or  otherwise to take any of the
actions specified in the foregoing items (a) through (g).

                  4.9 Tax  Matters.  All federal,  state,  local and foreign tax
returns  required  to be filed by or on behalf of DEI Texas have been filed with
the appropriate governmental authorities or bodies in all jurisdictions in which
such returns or pro forma returns are required to be filed. Seller has delivered
to Purchaser  true and  complete  copies of such returns in respect of the three
most  recent tax years of DEI  Texas.  All  federal,  state,  local and  foreign
income, profits, franchise,  sales, use, occupation,  property, excise and other
taxes  (including  interest and penalties and  withholdings  of tax) due from or
payable by DEI Texas have been paid on a timely basis or are adequately provided
for on the DEI Texas  Financial  Statements.  No issues  have been raised by the
Internal  Revenue Service upon audit with respect to DEI Texas, no state,  local
or foreign audits or other administrative proceedings or court proceedings exist
or have been  initiated with regarding to any taxes or tax returns of DEI Texas,
and none of the Dominion  Entities or DEI Texas has received any written  notice
that such an 

                                       66
<PAGE>

audit is pending or  threatened.  The books and records  maintained by DEI Texas
and the DEI Texas  Financial  Statements,  as of the date thereof and subject to
adjustments consistent with GAAP, accrue liabilities for all taxes which are not
yet due and payable, except where the failure to do so would not have a Material
Adverse Effect.

any  Affiliate  of  any  Dominion   Entity  (other  than  the  Company  and  its

respective  properties are bound. Each such Contract is in full force and effect

                  6.2 Further  Assurances.  The Dominion  Entities 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  necessary or advisable to  consummate  the
transactions  contemplated  by this  Agreement  or  required by the terms of any
Contract  to which any of the  Dominion  Entities,  the  Calpine  Entities,  the
Company and its Subsidiaries, DEI Texas or Bayonne is a party or by which any of
them or their respective  properties is bound. Each of the Dominion Entities and
Purchaser  agrees to execute,  and to cause its  Subsidiaries  and Affiliates to
execute,  such additional documents or instruments as any other party hereto may
from  time to time  reasonably  request  in order to  confirm  or carry  out the
transactions  contemplated by this Agreement;  provided,  however,  that no such
document or instrument shall expand a party's  liabilities or obligations beyond
that contemplated in this Agreement.

                  6.3  Books  and  Records.  On the  Closing  Date,  or as  soon
thereafter  as  reasonably  possible,  the  Dominion  Entities  will  deliver to
Purchaser  all of the books and  records of DEI Texas and all books and  records
maintained by or in the possession of the Dominion  Entities or their Affiliates
(including  DEI  in its  capacity  as  Administrator  under  the  Administrative
Services  Agreement)  relating to the Company  and its  Subsidiaries  (including
EC5).

                  6.4      [intentionally omitted]

                  6.5      Taxes.

                  (a) The Dominion Entities shall be responsible for 100% of all
Taxes related or  attributable  to DEI Texas for all periods up to and including
the Closing Date.  Purchaser  shall be responsible for 100% of all Taxes related
or  attributable  to the Company and its  Subsidiaries  (including  EC5) and DEI
Texas for all periods  after the Closing Date.  For purposes of this  Agreement,
(i) the amount of any taxable income or Taxes  attributable  to the  pre-Closing
portion of any taxable period beginning before and ending after the Closing Date
(the "Straddle Period") shall be determined by reference to the relative amounts
of the  Company's  or DEI  Texas',  as the case may be,  pre-tax net book income
(determined  in  accordance  with  GAAP)  in the  pre-Closing  and  post-Closing
portions of such Straddle  Period;  provided,  however,  that any  extraordinary
transaction  shall be allocated to the portion of such Straddle  Period in which
it occurred.

                  (b) DEI shall  prepare  and timely file all Tax Returns of DEI
Texas for all tax periods  ending  before the Closing  Date and shall  cooperate
with and, if requested, assist Purchaser in preparing and filing all Tax Returns
of DEI Texas for all tax periods ending on or after the Closing Date,  including
any Straddle  Period.  The Dominion  Entities  shall also cooperate with and, if
requested,  assist  Purchaser  and the Company in  preparing  and 

                                       71
<PAGE>

filing all Tax Returns of the Company and its  Subsidiaries  for all tax periods
ending  on or before  December  31,  1998  which  have not been  filed as of the
Closing Date.

                  (c) The Tax  Returns  referred to in Section  6.5(b)  shall be
prepared in a manner consistent with past practice,  unless a contrary treatment
is required by an intervening  change in the applicable  law. DEI shall cause to
be  made  available  to  Purchaser  a copy  of any  Tax  Return  that  is  DEI's
responsibility  under  Section  6.5(b),  and  Purchaser  shall  cause to be made
available to the Dominion  Entities a copy of any Tax Return relating to any tax
period  ending  before  the  Closing  Date  and  any  Straddle  Period  that  is
Purchaser's  responsibility under Section 6.5(b), in each case together with all
relevant work papers and other  information.  Each such Tax Return shall be made
available  for review no later than twenty (20)  Business  Days prior to the due
date (including all extensions) for the filing of such Tax Return. A copy of any
such Tax Return  shall be provided to the  Dominion  Entities or  Purchaser,  as
applicable, no later than ten (10) Business Days after such Tax Return is filed.

                  (d) DEI and  Purchaser  shall each  notify the other  party in
writing within 30 days of receipt of written notice of any pending or threatened
Tax examination,  audit or other  administrative or judicial  proceeding (a "Tax
Contest")  that could  reasonably  be expected to affect the Taxes for which the
other party is responsible under Section 6.5(a). If the recipient of such notice
of a Tax  Contest  fails to provide  such notice to the other  party,  the other
party shall not be responsible for any Taxes,  including interest and penalties,
to the extent they would have been  avoided or which would not have been payable
had such party received timely notice of the Tax Contest.

                  (e) Except as  provided in the last  sentence of this  Section
6.5(e),  if a Tax  Contest  relates  to any Taxes for which any of the  Dominion
Entities is responsible in full hereunder,  the Dominion Entities shall at their
expense  control the  defense  and  settlement  of such Tax  Contest.  Except as
provided  in the last  sentence  of this  Section  6.5(e),  if such Tax  Contest
relates to any period beginning after the Closing Date or to any Taxes for which
Purchaser is responsible in full  hereunder,  Purchaser shall at its own expense
control the defense and settlement of such Tax Contest. The party not in control
of the defense shall have the right to observe the conduct of any Tax Contest at
its expense,  including through its own counsel and other professional  experts.
The  Dominion  Entities  and  Purchaser  shall  jointly  control the defense and
settlement of any Tax Contest  relating to a Straddle  Period,  and the fees and
expenses  related thereto shall be paid 50% by the Dominion  Entities and 50% by
Purchaser.

                  (f)  Notwithstanding  anything  to  the  contrary  in  Section
6.5(e), to the extent that an issue raised in any Tax Contest  controlled by one
party or jointly  controlled could materially  affect the liability for Taxes of
the other party, the controlling  party shall not, and neither party in the case
of joint control shall, enter into a final settlement without the consent of the
other party,  which consent shall not be  unreasonably  withheld.  Where a party
withholds  its  consent  to any final  settlement,  that party may  continue  or
initiate further proceeding,  at its own expense, and the liability of the 

                                       72
<PAGE>

party that wished to settle (as between the  consenting  and the  non-consenting
party) shall not exceed the liability that would have resulted from the proposed
final settlement (including interest,  additions to Tax, and penalties that have
accrued  at that  time),  and  the  non-consenting  party  shall  indemnify  the
consenting party for such Taxes.

                  6.6  Confidentiality.  After the Closing  Date,  the  Dominion
Entities shall not use,  disclose or provide,  and shall cause their  Affiliates
not to use, disclose or provide, directly or indirectly, to any other Person any
confidential   or  proprietary   information   relating  to  the  Company,   its
Subsidiaries,  DEI Texas or Bayonne  except (i) as is  required  pursuant to any
applicable Legal Requirement,  (ii) information that was or becomes available in
the public domain  without any breach of any  confidentiality  obligation by the
Dominion  Entities or their  Affiliates,  or (iii) in accordance with and to the
extent provided in Section 3.6(b).

                  6.7  Employment  Matters.  The  Dominion  Entities  consent to
Purchaser or its Affiliates entering into direct discussions with their or their
Affiliates'  employees who are currently  performing services for the Company or
its  Subsidiaries  regarding  possible  future  employment  by  Purchaser or its
Affiliates;  provided,  however,  Purchaser  and  its  Affiliates  shall  not be
obligated  to  offer  employment  to  any  such  employees.  Purchaser  and  its
Affiliates  shall not incur any liability as a result of such  discussions.  The
Dominion  Entities  shall  remain  liable for all  salary,  benefits,  severance
payments,  bonus  payments and other payments of any kind due or payable to such
employees  (to and  including  the date of their  employment by Purchaser or its
Affiliates  in  the  case  of  employees  who  are  hired  by  Purchaser  or its
Affiliates),  except that the foregoing shall not affect DEI's rights to recover
any such amounts as Administrator under the Administrative Services Agreement.

                  6.8      Certain Organizational Matters.

                  (a) Seller and Purchaser  each agree to vote their  respective
shares of stock in the  Company,  and to cause the  respective  directors of the
Company  appointed  by them to vote,  in favor of, and for the  adoption  of all
necessary  resolutions  and the taking of all  necessary  actions  for,  (i) the
payment of any  Additional  Dividend which may be payable as provided in Section
2.3 above and (ii) the  redemption  by the Company of the Redeemed TCC Stock and
the  payment of the  Redemption  Payments  to Seller as  provided in Article III
above.

                  (b) Subject to the satisfaction of the conditions precedent to
their  respective  obligations  hereunder,  the Dominion  Entities and Purchaser
hereby agree to terminate, and Purchaser shall cause Calpine to terminate, as of
the  Closing  Date,  (i) the  Stockholders  Agreement,  (ii) the  Reorganization
Agreement,  (iii)  the  Agreement  Regarding  Stockholders  Agreement,  (iv) the
Override  and  Standstill  Agreements,  and (v) the Equity  Support  Agreements;
provided,  however,  that the termination of such agreements shall not terminate
(x) any releases of liabilities given or contained in any such agreements or (y)
any  obligations  of  the  parties  thereto,  including  payment  and  indemnity
obligations,  arising out of or relating to the period prior to the Closing Date
or events or  transactions  occurring  prior to the Closing 

                                       73
<PAGE>

Date,  including  the  indemnity  obligations  under  Section 3 of  Amendment of
Reorganization  Agreement  dated as of June 30, 1991,  except that all indemnity
and other obligations of either Dominion Entity or DRI under the  Reorganization
Agreement,  to the extent (but only to the extent) that such  obligations  cover
the matters  disclosed in item 1 of Schedule  4.15B,  shall  terminate as of the
Closing Date; provided,  further,  that upon the termination of such agreements,
each of the parties  thereto shall release the other parties from,  and shall be
released by the other parties from, any further obligations or liabilities under
such agreements  arising out of or relating to events or transactions  occurring
after the Closing Date. The Dominion Entities and Purchaser agree to execute and
deliver,  and to cause their  respective  Affiliates to execute and deliver,  at
Closing such  agreements  and  instruments  as may be necessary to effectuate or
evidence such termination and any continuing obligations or releases.

                  6.9 Certain Consents and Releases.  The Dominion  Entities and
Purchaser  shall  each use all  commercially  reasonable  efforts  to obtain all
consents and releases of liability  listed on Schedule 6.9;  provided,  however,
that "commercially reasonable efforts" shall not be deemed to require any of the
Dominion Entities or Purchaser to make any payments to any of the Persons listed
on Schedule 6.9 in order to obtain such consents and approvals.

        6.10  Transaction  Costs.  Each of the Dominion  Entities and  Purchaser
shall bear and pay all of the costs,  fees and expenses incurred by it or on its
behalf in connection with the transactions contemplated by this Agreement.

                  6.11  DEI  Texas  Dividend,   Receivables  and  Payables.  The
Dominion  Entities  may, at their  option,  cause DEI Texas to declare and pay a
dividend to DEI, as its sole  shareholder  at that time, a dividend equal to the
sum of (i) all cash held by DEI Texas on the Closing Date and (ii) all rights to
receive  payment of accounts  receivable of DEI Texas existing as of the Closing
Date; provided,  however,  that the foregoing dividend shall be net of and shall
be reduced by the amount of all outstanding  liabilities of DEI Texas (including
accounts  payable to DEI and its Affiliates) as of the Closing Date,  other than
the  liabilities  described in items 1 and 2 on Schedule  4.7.  Purchaser  shall
cause DEI Texas to use commercially  reasonable efforts to collect such accounts
receivable  and shall remit to DEI the  amounts  collected,  net of  liabilities
payable by DEI or  reimbursable  to Purchaser or DEI Texas,  during the previous
calendar  month  (and not  previously  paid to or for the  benefit of DEI) on or
before the twentieth (20th) day of the next following calendar month, commencing
with the  calendar  month  following  the one in which the Closing  Date occurs,
until all such  receivables and liabilities have been collected or paid in full.
Regardless of whether or not such a dividend is declared,  DEI shall be entitled
to receive all amounts  collected  with  respect to accounts  receivable  of DEI
Texas  existing as of, or relating to any period  prior to, the Closing Date and
shall be  responsible  for and shall pay, or shall  reimburse  Purchaser and DEI
Texas for the payment of, all accounts  payable of DEI Texas  existing as of, or
relating to any period prior to, the Closing  Date,  other than the  liabilities
described in items 1 and 2 on Schedule 4.7.

<PAGE>

                  6.12 Amounts  Payable With Respect to Bayonne  Interest or Due
Under Reorganization  Agreement.  Seller shall be entitled to receive and retain
all payments or  distributions on account of the Bayonne Interest for the period
prior to the  Closing  Date and shall  continue to be  responsible  for all cash
calls, claims, losses, damages,  expenses or liabilities relating to the Bayonne
Interest as provided under the Reorganization  Agreement for the period prior to
the Closing  Date,  except that all indemnity  and other  obligations  of either
Dominion Entity or DRI under the  Reorganization  Agreement,  to the extent (but
only to the extent) that such obligations  cover the matters disclosed in item 1
of Schedule 4.15B,  shall terminate as of the Closing Date. Without limiting the
parties' rights and obligations  under Section 6.8(b),  on or before the Closing
Date,  Purchaser  and  its  Affiliates  shall  pay all  amounts  due  under  the
Reorganization Agreement for all periods ending on the Closing Date.

                  6.13 Change of Name. Promptly following the Closing, Purchaser
shall take all steps  necessary  to amend the articles of  incorporation  of DEI
Texas to change the name of DEI Texas to a name which does not include  "DEI" or
"Dominion" or other similar names or references to DEI or its Affiliates.  After
completing such name change, neither Purchaser nor DEI Texas shall use the names
"DEI"  or  "Dominion"  in  any  fashion  in  connection  with  their  respective
businesses.

                  6.14  Intercompany  Accounts.  Without  limiting  the parties'
rights and  obligations  under Section 6.11, on the Closing Date,  DEI Texas and
the Company shall pay all amounts  owed, as of the Closing Date, to Seller,  DEI
and their Affiliates and to Purchaser and its Affiliates.

                  6.15  Termination of Insurance  Policies.  DEI shall take such
actions as are  necessary to terminate,  effective as of the Closing  Date,  the
existing insurance policies which DEI maintains in favor of the Company pursuant
to the Administrative Services Agreement. DEI may retain one half of any premium
refunds and other amounts  received in connection  with the  termination of such
insurance  policies  and  shall  pay or cause to be paid to  Purchaser  (or,  at
Purchaser's  election,  the  Company)  the  other  one half of all such  premium
refunds and other amounts.

and  expenses)  incurred or suffered by any such Person  directly or  indirectly
arising  or   resulting   from  any   Excluded   Liability   or  breach  of  any
representation, warranty, covenant or obligation of any of the Dominion Entities
in this  Agreement or any agreement,  instrument,  certificate or other document
delivered  pursuant to this  Agreement by or on behalf of any  Dominion  Entity;
provided  that the  aggregate  liability  of the  Dominion  Entities  under this
Section 8.1 shall not exceed the Purchase Price.

                  (b)  Purchaser  hereby  indemnifies  and  holds  harmless  the
Dominion  Entities  and  their  respective  Affiliates,   directors,   officers,
employees,  agents,  successors  and  assigns  from  and  against  any  and  all
liabilities,  judgments,  claims,  settlements,  losses,  damages,  fees, liens,
taxes, penalties, obligations and expenses (including reasonable attorney's fees
and  expenses)  incurred or suffered by any such Person  directly or  indirectly
arising or resulting from any breach of any representation,  warranty,  covenant
or  obligation  of Purchaser in this  Agreement  or any  agreement,  instrument,
certificate  or other  document  delivered  pursuant to this  Agreement by or on
behalf of Purchaser.

                  (c) The Indemnifying Party shall have the right, at its option
and at its own  expense,  to be  represented  by  counsel  of its  choice and to
participate in, or to take exclusive control of, the defense, negotiation and/or
settlement  of any  proceeding,  claim or demand  which  relates to any  amounts
indemnifiable or potentially  indemnifiable  under this Article VIII;  provided,
however,  that the Indemnified Party may participate in any such proceeding with
counsel  of  its  choice,  which  shall  be  at  its  own  expense,  unless  the
Indemnifying  Party does not pursue  with  reasonable  diligence  such  defense,
negotiation or settlement. The Indemnified Party shall have a right to notice of
any settlement,  and the Indemnifying Party shall not execute or otherwise agree
to any  settlement  agreement or consent  decree  which  provides for other than
monetary payment (including, but not limited to any with admission of liability,
restrictions  of  business  activities  or  criminal,  civil  or  administrative
penalties) without the Indemnified Party's prior written consent,  which consent
will  not  be  unreasonably   withheld.   Notwithstanding  the  foregoing,   the
Indemnified Party shall have the right to pay or settle any such claim, provided
that in such  event it  shall  waive  any  right to  indemnity  therefor  by the
Indemnifying Party, unless such payment or settlement follows the failure of the
Indemnifying  Party to assume  the  defense  of such  claim,  in which case such
payment or  settlement  will not result in any waiver of any right of  indemnity
with respect thereto.  If the Indemnifying  Party elects not to defend or settle
such proceeding,  claim or 

                                       79
<PAGE>

demand and the  Indemnified  Party defends,  settles or otherwise deals with any
such proceeding, claim or demand, which settlement may be without the consent of
the  Indemnifying  Party,  the  Indemnified  Party shall  provide ten (10) days'
advance written notice of any settlement to the Indemnifying  Party and will act
reasonably  and in accordance  with its good faith business  judgment,  but such
settlement by the Indemnified Party shall not relieve the Indemnifying  Party of
any of its  obligations  or liabilities  hereunder,  including its obligation to
indemnify the  Indemnified  Party for the costs of such defense and  settlement.
The  parties  shall  cooperate  fully  with each  other in  connection  with the
defense,  negotiation  or  settlement  of any such  legal  proceeding,  claim or
demand.

                  (d) After final  judgment or award shall have been rendered by
a court,  arbitration board or administrative  agency of competent  jurisdiction
and the  expiration  of the time in which to appeal  therefrom,  or a settlement
shall have been consummated, or the Indemnifying Party and the Indemnified Party
shall have arrived at a mutually binding agreement with respect to each separate
matter  indemnified  by the  Indemnifying  Party,  the  Indemnified  Party shall
forward  to the  Indemnifying  Party  notice  of any sums  due and  owing by the
Indemnifying  Party with respect to such matter and the Indemnifying Party shall
pay all of the sums so owing to the Indemnified Party within ten (10) days after
the date of such notice.

                  8.2 Notices.  In case any claim or litigation which might give
rise to any obligation of a party under this Article VIII (each an "Indemnifying
Party")  shall  come  to the  attention  of the  party  seeking  indemnification
hereunder (the "Indemnified Party"), the Indemnified Party shall promptly notify
the  Indemnifying  Party in writing of the  existence  and amount  thereof.  The
Indemnifying  Party shall promptly notify the Indemnified Party in writing if it
accepts such claim or litigation as being within its indemnification obligations
under this Article VIII.  Such response  shall be delivered no later than thirty
(30) days after the initial  notification from the Indemnified Party;  provided,
however, that if the Indemnifying Party reasonably cannot respond to such notice
within thirty (30) days, the Indemnifying Party shall respond to the Indemnified
Party as soon thereafter as reasonably possible. A failure to give timely notice
as provided in this Section 8.2 will not affect the rights or obligations of any
party  hereunder  except if, and only to the  extent  that,  as a result of such
failure,  the party  which was  entitled  to receive  such  notice was  actually
prejudiced as a result of such failure.

                  8.3 Insurance and Tax Benefits.  The amount of any claim by an
Indemnified  Party for  indemnification  pursuant to this  Article VIII shall be
computed net of insurance  proceeds and tax benefits received or receivable (and
likely to be received) by such Indemnified Party on account of such claim.

                  8.4   Applicability.   Subject  to  Section  8.5  below,   the
provisions of this Article VIII shall apply  notwithstanding  the sole, joint or
concurrent negligence, strict liability or other fault of the Indemnified Party.
If both  the  Indemnified  Party  and the  Indemnifying  Party  are  adjudicated
negligent  or  otherwise  at  fault  or  strictly  liable  without  fault,   the
contractual  indemnification  obligations under this Article VIII shall,

                                       80
<PAGE>

subject  to  Section  8.5,  continue,  but the  Indemnifying  Party  shall  only
indemnify the  Indemnified  Party for the percentage of  responsibility  for the
damage or injuries adjudicated to be attributable to the Indemnifying Party.

                  8.5   Limitation   on   Damages.   In  no  event   shall   the
indemnification  obligations  under  this  Article  VIII  or any  other  losses,
expenses  or  damages  recoverable  by any  party  hereunder  cover  or  include
consequential, incidental, special, indirect or punitive damages or lost profits
suffered  by any party  hereto,  whether  based on  statute,  contract,  tort or
otherwise,  and whether or not arising from the Indemnifying Party's sole, joint
or concurrent negligence, strict liability or other fault.

                  10.6 Benefits of Agreement. All of the terms and provisions of
this  Agreement  shall be binding  upon and inure to the  benefit of the parties
hereto and their  respective  successors and assigns.  This Agreement is for the
sole benefit of the parties hereto and not for the benefit of any third party.

                  10.7  Amendments and Waivers.  No  modification,  amendment or
waiver,  of any provision of, or consent  required by, this  Agreement,  nor any
consent to any departure from this Agreement, shall be effective unless it is in

or consent shall be effective only in the specific  instance and for the purpose
for which given.

                  10.8 Assignment. This Agreement and the rights and obligations
hereunder shall not be assignable or transferable by either party hereto without
the prior  written  consent of the other  parties  hereto.  Notwithstanding  the
foregoing,  (i)  Purchaser  may assign any or all of its rights and  obligations
hereunder to any wholly owned direct or indirect Subsidiary of Calpine, and upon
Seller's receipt of notice from Purchaser of any such assignment, Purchaser will
be  released  from  all  liabilities  and  obligations  hereunder,  accrued  and
unaccrued, such assignee will be deemed to have assumed,  ratified, agreed to be
bound by and perform all such  liabilities and  obligations,  and all references
herein to "Purchaser" shall thereafter be deemed references to such assignee, in
each case  without  the  necessity  for  further  act or evidence by the parties
hereto or such assignee; (ii) Purchaser and its permitted successors and assigns
may assign, transfer,  pledge or otherwise dispose of their rights and interests
hereunder to a trustee or lending  institution(s) for the purposes of financing;
provided, however, that no such assignment or disposition shall relive or in any
way  discharge  Purchaser  or its  permitted  successors  and  assigns  from the
performance  of their duties and  obligations  under this  Agreement;  and (iii)
Seller may assign any or all of its rights to receive  payment of any portion of
the Redemption Payments (but not any other rights,  including rights of audit or
inspection  associated  therewith)  to any Person or  Persons,  and the  Company
agrees,  upon direction from Seller,  to pay such assigned  Redemption  payments
directly to such  assignee(s);  provided,  however,  that payment by the Company
pursuant to any such notice of  assignment  from Seller  shall  constitute  full
performance  by the  Company  with  respect  to any  obligations  to  make  such
Redemption   Payments  to  Seller  hereunder;   provided,   further,   that  all
arrangements necessary to effect such assignments shall be at Seller's sole cost
and expense.  The Dominion  Entities agree to execute and deliver such documents
as may be reasonably  necessary to  accomplish  any such  assignment,  transfer,
conveyance,  pledge or disposition  of rights  hereunder so long as the Dominion
Entities'  rights  under  this  Agreement  are  not  thereby  altered,  amended,
diminished or otherwise impaired.

        10.9 Governing Law. This agreement shall be governed by and construed in
accordance with the laws of the State of New York, without regard to conflict of
laws principles.

                  10.10 Consent to Jurisdiction.  Each of the Dominion  Entities
and Purchaser  hereby  submits to the  nonexclusive  jurisdiction  of the United

                                       83
<PAGE>

States  District  Court for the  Southern  District of New York and of any state
court  sitting in the Borough of Manhattan,  New York,  New York for purposes of
all legal  proceedings  arising  out of or  relating  to this  Agreement  or the
transactions  contemplated  hereby.  Each of the Dominion Entities and Purchaser
irrevocably  waives, to the fullest extent permitted by law, any objection which
it may now or hereafter  have to the laying of the venue of any such  proceeding
brought in such a court and any claim that any such proceeding brought in such a
court has been brought in an inconvenient  forum. Any and all service of process
and any other notice in any such  proceeding  shall be effective  against any of
the Dominion  Entities and  Purchaser if given  personally  or by  registered or
certified  mail,  return receipt  requested,  or by any other means of mail that
requires a signed receipt,  postage  prepaid,  mailed to such Dominion Entity or
Purchaser.


IN WITNESS  WHEREOF,  each of the parties has caused this  Agreement  to be duly
executed and delivered as of the day and year first above written.
