ASSET PURCHASE AGREEMENT

This Asset Purchase Agreement (this "Agreement")
  dated as of June 1, 2004 (the "Agreement Date") is made
  and entered into by and between PPL Sundance Energy, LLC, a Delaware
  limited liability company ("Seller"), and Arizona
  Public Service Company, an Arizona corporation ("Purchaser").

RECITALS

Seller owns a generating plant in Pinal County, Arizona, having
  a nominal generating capacity of 450 megawatts.

Seller desires to sell and assign to Purchaser, and Purchaser
  desires to purchase and assume from Seller, the Purchased Assets and the Assumed
  Liabilities (each as hereinafter defined) on the terms and subject to the conditions
  set forth herein.

STATEMENT OF AGREEMENT

Now, therefore, in consideration of the premises and the mutual
  representations, warranties, covenants and agreements set forth in this Agreement,
  and for other good and valuable consideration, the receipt and sufficiency of
  which are hereby acknowledged, the Parties agree as follows:

ARTICLE I
  DEFINITIONS; CONSTRUCTION

1.1    Definitions. Capitalized
  terms used in this Agreement have the meanings given to them in Appendix I to
  this Agreement.

1.2    Construction.

(a)    In this Agreement, unless expressly
  provided otherwise:

(i)    
  Unless otherwise specified, all article, section, subsection, schedule, exhibit
  and appendix references used in this Agreement are to articles, sections, subsections,
  schedules, exhibits and appendices to this Agreement. The exhibits, schedules
  and appendices attached to this Agreement constitute a part of this Agreement
  and are incorporated herein for all purposes.

(ii)    If
  a term is defined as one part of speech (such as a noun), it shall have a corresponding
  meaning when used as another part of speech (such as a verb). Unless the context
  of this Agreement clearly requires otherwise the singular shall include the
  plural and the plural shall include the singular wherever and as often as may
  be appropriate, and words importing the masculine gender shall include the feminine
  and neutral genders and vice versa. The words "includes" or "including"
  shall mean "including without limitation," the words "hereof,"
  "hereby," "herein," "hereunder" and similar terms
  in this Agreement shall refer to this Agreement as a whole and not any particular
  section or article in which such words appear and any reference to a Law shall
  include any amendment thereof or any consolidation, amendment, reenactment,
  extension, replacement or successor thereto and any rules and regulations promulgated
  thereunder. References to "or" shall be deemed to be disjunctive but
  not necessarily exclusive (i.e., unless the context dictates otherwise, "or"
  shall be interpreted to mean "and/or" rather than "either/or").
  Currency amounts referenced herein, unless otherwise specified, are in U.S.
  Dollars.

(iii)    A
  reference to (A) a day (other than a Business Day) is a reference to a calendar
  day, (B) a month is a reference to a calendar month and (C) a year is a reference
  to a calendar year. A reference to a time is a reference to the time in effect
  in Phoenix, Arizona on the relevant date. When a period of time is specified
  to run from or after a given day or the day of an act or event, it is to be
  calculated exclusive of such day; and where a period of time is specified as
  commencing on a given day or the day of an act or event, it is to be calculated
  inclusive of such day. Whenever this Agreement refers to a number of days, such
  number shall refer to calendar days unless Business Days are specified. Whenever
  any action must be taken hereunder on or by a day that is not a Business Day,
  then such action may be validly taken on or by the next day that is a Business
  Day. A reference to a day (other than a Business Da y) is a reference to a period
  of time commencing at midnight Phoenix time and ending the following midnight
  Phoenix time. A reference to a Business Day is a reference to a period of time
  commencing at 9:00 a.m. Phoenix time on a Business Day and ending at 5:00 p.m.
  Phoenix time on the same Business Day.

(iv)    All
  accounting terms used herein and not expressly defined herein shall have the
  meanings given to them under GAAP.

(b)    Time is of the essence in this Agreement.

(c)    Each Party acknowledges that it
  and its attorneys have been given an equal opportunity to negotiate the terms
  and conditions of this Agreement and that any rule of construction to the effect
  that ambiguities are to be resolved against the drafting Party or any similar
  rule operating against the drafter of an agreement shall not be applicable to
  the construction or interpretation of this Agreement.

  subject to adjustment pursuant to Section 3.7 and Section 10.1(g)
  (the "Purchase Price").

3.2    Proration.

(a)    Purchaser and Seller agree that,
  except as otherwise set forth in this Agreement, all of the items normally prorated,
  including those listed below, relating to the Business and the Purchased Assets
  shall be prorated as of the effective time of the Closing on the Closing Date,
  with Seller liable to the extent such items relate to any time period through

(i)    any rent, Taxes and other items

  to and assumed by Purchaser hereunder;

(ii)    any permit, license or registration
  fees with respect to any Transferred Permit; and

(iii)    charges for water, telephone,
  electricity and other utilities.

(b)    Purchaser and Seller agree that
  Property Taxes with respect to the Business or the ownership and the operations
  of the Purchased Assets or the Project shall be prorated as follows:

(i)    Seller shall be liable for and shall
  pay when due all Property Taxes having a lien date in the year before the calendar
  year of the Closing Date.

(ii)    Seller shall be liable for and
  shall pay when due all Property Taxes having a lien date in the same calendar
  year as the Closing Date; and

(iii)    Property Taxes having a lien date
  in the calendar year following the year of the Closing Date shall be paid by
  Purchaser; however, such Property Taxes shall be prorated with (A) Seller being
  liable for that portion of the Property Taxes calculated by multiplying (1)
  the final determined Property Tax liability by (2) the number of days beginning
  with January 1 in the year of Closing up to and including the Closing Date divided
  by three hundred sixty-five (365) days, and (B) Purchaser being liable for that
  portion of the Property Taxes calculated by multiplying (1) the final determined
  Property Tax liability by (2) the number of days after the Closing Date up to
  and including December 31 in the year of Closing divided by three hundred sixty-five
  (365) days. Schedule 3.2(b) illustrates the operation of this Section
  3.2(b). After each payment of Property Taxes referred to in this Section
  3.2(b)(iii) by Purchaser, Purchaser shall notify Seller in writing of the
  total amount of Property Taxes paid and, as to that payment, the prorated amount
  for which Seller is liable. Seller shall reimburse Purchaser such prorated amount
  within fifteen (15) days after receipt of the notice from Purchaser.

(c)    In the event that actual figures
  are not available at the Closing Date, prorations required by Section 3.2(a)
  shall be calculated as follows:

(i)    Such proration shall be based upon
  the actual fee, cost or amount of the specific item for the most recent preceding
  year (or appropriate period) for which an actual fee, cost or amount paid is
  available.

(ii)    Upon the request of either Seller
  or Purchaser, made within sixty (60) days of the date that any actual amount
  previously estimated in accordance with Section 3.2(c)(i) becomes available
  (the "Request Date"), the Parties shall (A) calculate
  the prorated amounts using the actual available amounts (the "Actual
  Prorated Amounts"), (B) calculate the difference between the originally
  estimated prorations (the "Estimated Prorated Amounts")
  and the Actual Prorated Amounts (the "Prorated Difference"),
  and (C) the Party that at Closing paid less than the Actual Prorated Amount
  due from such Party based upon the Estimated Prorated Amounts shall pay the
  Prorated Difference to the other Party within sixty (60) days of the Request
  Date.

3.3    Closing. The Closing
  shall take place in Phoenix at the offices of Moyes Storey at 10:00 A.M. Phoenix
  time, on the third Business Day after the conditions to Closing set forth in
  Articles VIII and IX (other than actions to be taken or items
  to be delivered at Closing) have been either satisfied or waived by the Party
  entitled to waive such conditions, or on such other date and at such other time
  and place as Purchaser and Seller mutually agree in writing. All actions scheduled
  in this Agreement for the Closing Date shall be deemed to occur simultaneously
  at the Closing. Subject to the provisions of Article X, failure to consummate
  the purchase and sale provided for in this Agreement on the date determined
  pursuant to this Section 3.3 will not result in the termination of this
  Agreement and will not relieve any Party of any obligation under this Agreement.
  The Closing shall be effective for all purposes as of 11:59:59 P.M. Phoenix
  time on the Closing Date.

(h)    such other documents as Seller may
  reasonably request to carry out the purposes of this Agreement.

3.6    Allocation of Purchase Price.

(a)    Seller and Purchaser agree that
  prior to the Closing, the Purchase Price shall be allocated among the Purchased
  Assets in accordance with an allocation schedule (the "Purchase Price
  Allocation Schedule") agreed upon by Purchaser and Seller, which
  shall be prepared in a manner required by Section 1060 of the Code and any other
  applicable Law and delivered by Purchaser to Seller prior to the Closing. Seller
  and Purchaser each shall prepare a mutually acceptable and substantially identical
  IRS Form 8594 "Asset Acquisition Statements Under Section 1060" consistent
  with the Purchase Price Allocation Schedule which the Parties shall use to report
  the transactions contemplated by this Agreement to the applicable Taxing Authorities.
  Each of Seller and Purchaser agrees to provide the other promptly with any other
  information required to complete IRS Form 8594. Each Party agrees that it shall
  not, without the consent of the other Party, take a position on any Tax Return,
  or before any Taxing Authority in connection with the examination of any Tax
  Return or in any subsequent judicial proceeding, that is in any manner inconsistent
  with the terms of the Purchase Price Allocation Schedule. In recognition of
  Seller's status as a disregarded entity for U.S. federal and Arizona income
  tax purposes, Purchaser agrees that Seller's responsibilities and obligations
  under this Section 3.6(a) shall be satisfied by Seller cooperating with
  its sole member with respect to such responsibilities and obligations.

(b)    If Purchaser and Seller are unable
  to agree upon the Purchase Price Allocation Schedule within fifteen (15) days
  prior to the scheduled Closing Date, Purchaser and Seller shall refer the matter
  to Independent Accountants, which shall determine the Purchase Price Allocation
  Schedule (including any valuations) in accordance with the provisions set forth
  in this Section 3.6(b). The Independent Accountants shall be instructed
  to deliver to Purchaser and Seller a written determination of the Purchase Price
  Allocation Schedule within ten (10) days from the date of referral thereof to
  the Independent Accountants. For purposes of this Section 3.6(b) and
  whenever the Independent Accountants are retained to resolve a dispute between
  the Parties under this Agreement, the Independent Accountants may determine
  the issues in dispute following such procedures, consistent with the provisions
  of this Agreement, as they deem appropriate in the circumstances and wi th reference
  to the amounts in issue. The Parties do not intend to impose any particular
  procedures upon the Independent Accountants, it being the desire of the Parties
  that any such disagreement shall be resolved as expeditiously and inexpensively
  as reasonably practicable. The Independent Accountants shall have no liability
  to the Parties in connection with such services except for acts of bad faith,
  willful misconduct or gross negligence, and the Parties shall provide such indemnities
  to the Independent Accountants as they may reasonably request. Except in the
  case of fraud or manifest error, the finding of the Independent Accountants
  shall be final and binding on the Parties. Purchaser and Seller shall share
  equally the fees and disbursements of the Independent Accountants in connection
  with resolving the dispute.

3.7    Minimum Inventory Amount Adjustment.

(a)    The Purchase Price will be increased
  on a dollar-for-dollar basis to the extent that the Post-Closing Inventory Amount
  Determination (as defined below) is greater than the Minimum Inventory Amount
  (provided that such increase shall in no event exceed $100,000) and decreased
  on a dollar-for-dollar basis to the extent that the Post-Closing Inventory Amount
  Determination is less than the Minimum Inventory Amount.

(b)    At least five (5) Business Days
  prior to the execution and delivery hereof, Seller shall have provided Purchaser
  with a certificate containing a description, part number, quantity on hand,
  average unit cost and extended value (quantity times average unit cost) with
  respect to each class of inventory as of the last day of each calendar month
  between January 1, 2003 and December 31, 2003. During the Interim Period, Purchaser
  will be entitled to conduct onsite test counts of the spare parts inventory
  in accordance with Section 6.2.

(c)    Within sixty (60) days after the
  Closing Date, Purchaser will deliver to Seller written notice (the "Inventory
  Adjustment Notice") of Purchaser's post-Closing determination of
  the spare parts in inventory as of the Closing Date (the "Post-Closing
  Inventory Amount Determination"), as derived from Purchaser's physical
  review of the spare parts in inventory, the records (financial and otherwise)
  relating to such spare parts, and the Transferred Contracts. The Inventory Adjustment
  Notice will contain reasonable detail as to how the Post-Closing Inventory Amount
  Determination was determined by Purchaser. Within twenty (20) days after Seller's
  receipt of the Inventory Adjustment Notice, Seller will notify Purchaser in
  writing of Seller's acceptance or rejection of the Post-Closing Inventory Amount
  Determination as set forth in the Inventory Adjustment Notice. Any notice of
  rejection by Seller must include the reasons f or such rejection and, if appropriate,
  Seller's proposed calculation of the Post-Closing Inventory Amount Determination.
  If (i) by written notice to Purchaser, Seller accepts the Post-Closing Inventory
  Amount Determination as set forth in the Inventory Adjustment Notice, or (ii)
  Seller fails to deliver any notice of acceptance or rejection of the Post-Closing
  Inventory Amount Determination within the prescribed twenty (20)-day period
  (which failure will result in Seller being deemed to have irrevocably accepted
  and agreed with the Post-Closing Inventory Amount Determination), the Post-Closing
  Inventory Amount Determination as set forth in the Inventory Adjustment Notice
  will be final and binding on the Parties.

3.8    Adjustment Disputes.

(a)    If Seller delivers written notice
  to Purchaser under Section 3.7(c) of rejection of the Post-Closing Inventory
  Amount Determination as set forth in the Inventory Adjustment Notice, Seller
  and Purchaser will promptly (and in any event within ten (10) Business Days
  after the date of delivery of Seller's notice of rejection to Purchaser) cause
  their respective representatives to confer with each other with a view to resolving
  any such matter. If such Parties' representatives are unable to resolve any
  such matter within thirty (30) days after the date of delivery of Seller's notice
  of rejection to Purchaser, Seller and Purchaser will refer the dispute to Independent
  Accountants for review and final determination of the Post-Closing Inventory
  Amount Determination. The Independent Accountants shall be instructed to deliver
  to Purchaser and Seller a written determination of the Post-Closing Inventory
  Amount Determination within ten (10) Business Days from the d ate of referral
  thereof to the Independent Accountants. The Independent Accountants may request
  of Seller or Purchaser such documents and information as may be necessary or
  appropriate for proper determination of any such matter, and such Parties will
  cooperate to promptly satisfy any such request. Except in the case of fraud
  or manifest error ,the determination by the Independent Accountants of the Post-Closing
  Inventory Amount Determination will be final and binding on the Parties. Seller
  and Purchaser will equally share the fees and disbursements of the Independent
  Accountants in undertaking such review and determination.

(b)    Within five (5) Business Days after
  the final agreement of Seller and Purchaser, the final determination by the
  Independent Accountants or the deemed acceptance by Seller (as the case may
  be) of the Post-Closing Inventory Amount Determination, either:

(i)    Purchaser will pay to Seller, by
  wire transfer of immediately available funds, the amount (if any) by which the
  Post-Closing Inventory Amount Determination exceeds the Minimum Inventory Amount
  (provided that such adjustment shall in no event exceed $100,000), or

(ii)    Seller will pay to Purchaser, by
  wire transfer of immediately available funds, the amount (if any) by which the
  Post-Closing Inventory Amount Determination is less than the Minimum Inventory
  Amount.

3.9    Change in Name. Not
  more than ten (10) Business Days after the Closing Date, Purchaser shall remove
  all signs or other indications of ownership at the Project or on the Purchased
  Assets that reference Seller.

  of the Purchased Assets or the nature of the business conducted by it make such
  qualification or licensing necessary, except in those jurisdictions where the
  failure to be so qualified or licensed would not reasonably be expected to result
  in a material adverse effect on Seller's ability to perform its obligations
  hereunder. Seller has made available to Purchaser true, correct and complete
  copies of Seller's Charter Documents.

4.2    Authority. Seller
  has all requisite limited liability company power and authority to execute and

  action. This Agreement and each of the Ancillary Agreements to which Seller
  is a party have been duly and validly executed and delivered by Seller and constitute

  it or any of the Purchased Assets may be bound, except for any such defaults
  or consents (or rights of termination, cancellation or acceleration) as to which
  requisite waivers or consents have been obtained or which would not, individually
  or in the aggregate, reasonably be expected to have a Seller Material Adverse
  Effect;

(ii)    result in the creation or imposition
  of any Lien upon any of the Purchased Assets;

6.1    Regulatory and Other Approvals.

(a)    Seller covenants that, from the
  date hereof until the earlier of the Closing or termination of this Agreement
  in accordance with its terms (the "Interim Period"),
  Seller will, in order to consummate the transactions contemplated hereby (including
  the transfer of the Transferred Permits to Purchaser), take such reasonable
  steps as are necessary or desirable, and proceed diligently and in good faith
  and use all reasonable efforts to expedite and obtain the Seller Approvals and
  Seller Consents, and to make all filings with, and to give all notices to, Governmental
  Authorities, and provide such other information and communications to such Governmental
  Authorities or other Persons, as such Governmental Authorities or other Persons
  may reasonably request in connection therewith. Purchaser covenants that, during
  the Interim Period, Purchaser will, in order to consummate the transactions
  contemplated hereby (including the transfer of the Transfer red Permits to Purchaser),
  take such reasonable steps as are necessary or desirable, and proceed diligently
  and in good faith and use all reasonable efforts to expedite and obtain the
  Purchaser Approvals, and to make all filings with, and to give all notices to,
  Governmental Authorities, and provide such other information and communications
  to such Governmental Authorities or other Persons, as such Governmental Authorities
  or other Persons may reasonably request in connection therewith. Without limiting
  the generality of the foregoing, each Party shall provide, and cause its respective
  Affiliates to provide, true and accurate information in a timely manner with
  respect to all filings with and notices to Governmental Authorities. Nothing
  in this Section 6.1(a) shall be construed to require (i) Purchaser to
  take any action with respect to filings with or notices to Governmental Authorities
  that in Purchaser's discretion could materially adversely affect any other proceeding
  with such Governmental Auth orities or (ii) Seller to take any action that would
  result in the transfer of a Permit to Purchaser prior to Closing. Each Party
  will cooperate fully in good faith with the other Party with respect to all
  filings that are required by Law or that such other Party elects to make in
  connection with the transactions contemplated under this Agreement. Each Party
  will also cooperate fully in good faith with the other in obtaining all material
  consents and approvals required under this Agreement.

(b)    Each Party will provide the other
  Party with a reasonable opportunity to review and provide prior comment upon
  any notices, filings or other submissions that the Party plans to deliver or
  submit to any Governmental Authority, and will promptly provide to such other
  Party a copy of any such notices or filings. Notwithstanding the foregoing,
  the Parties recognize that as a result of the short time frames available for
  the preparation and filing of many documents required to be filed in the proceedings
  seeking the ACC Order, each Party may be able to afford the other Party only
  a very brief opportunity for prior review of or comment on filings in such proceedings.
  Each Party will provide prompt notification to the other Party when any approval
  referred to in Section 6.1(a) is obtained, taken, made or given, as applicable,
  and will advise the other Party of any material communications with any Governmental
  Authority from which such approval is required regar ding any pending application
  or request for approval by such Governmental Authority of any of the transactions
  contemplated by this Agreement.

(c)    Each Party shall prepare, as soon
  as is reasonably practicable following the execution of this Agreement, all
  necessary filings in connection with the transactions contemplated by this Agreement
  that may be required to be made by such Party at FERC or under the HSR Act.
  Each Party shall submit such filings as soon as practicable, but, in the case
  of filings under the HSR Act, in no event later than thirty (30) days after
  the date that the Parties file their application with FERC, under Section 203
  of the Federal Power Act of 1935, and Part 33 of the FERC Regulations (18 CFR
  Part 33), for the approval of the transactions contemplated by this Agreement.
  Unless the Parties agree otherwise at the time of filing, the Parties shall
  request expedited treatment of filings at FERC and early termination of the
  waiting period under the HSR Act. The Parties shall promptly make any appropriate
  or necessary subsequent or supplemental filings and shall cooperate in the prepa
  ration of such filings as is reasonably necessary and appropriate.

(d)    To the extent that any Transferred
  Contract or Transferred Permit is not assignable without the consent of another
  party, then this Agreement shall not constitute an assignment or attempted assignment
  thereof if such assignment or attempted transfer thereof would constitute a
  breach thereof or a default thereunder. Without limiting the provisions of Section
  6.1(a), if any such consent shall not be obtained, or if any attempted assignment
  of a Transferred Contract or Transferred Permit would be ineffective or would
  impair Purchaser's rights and obligations such that Purchaser would not in effect
  acquire the benefit of substantially all of such rights and obligations, Seller
  shall cooperate with Purchaser in any reasonable arrangement, to the extent
  legally permissible, designed to provide for Purchaser the benefits intended
  to be assigned to Purchaser under the Transferred Contract or Transferred Permit,
  including enforcement at the cost and for the accoun t of Purchaser of any and
  all rights of Seller against the other party thereto arising out of the breach
  or cancellation thereof by such party or otherwise. If and to the extent that
  such arrangement is not made in a manner reasonably satisfactory to Purchaser,
  Purchaser shall have no obligation pursuant to Section 2.3 or otherwise
  with respect to such Transferred Contract or Transferred Permit. The provisions
  of this Section 6.1(d) shall not affect the right of Purchaser not to
  consummate the transactions contemplated by this Agreement if the conditions
  to Purchaser's obligations set forth in Section 8.5 have not been fulfilled.

  Assets are bound, all Books and Records, including all environmental records,
  permits, and compliance audits relating to the Business or the Project, and
  the officers and employees of Seller or its Affiliates who have significant
  responsibility for Seller, but only to the extent that such access does not
  unreasonably interfere with the Business of Seller and that such access is reasonably
  related to the Purchaser's obligations and rights hereunder; provided
  that Seller shall have the right to (i) have a Representative of Seller present
  for any communication with employees or officers of Seller or its Affiliates
  an d (ii) impose reasonable restrictions and requirements upon Purchaser and

  notice of the date and time on which any such entry upon the Real Property is
  proposed to occur. Promptly upon completion of any such entry, Purchaser shall,

  and restore any affected Real Property and any other affected property to its
  original condition. Purchaser hereby agrees to indemnify, defend and hold harmless

  of its Affiliates or any of its or their respective Representatives, agents,
  contractors or subcontractors pursuant to this Section 6.2. The provisions

  Property leased under the Martin Farms Lease shall be subject to the rights
  of the tenant under such lease. Without limiting the foregoing, Seller shall

  in gaining access to and inspecting such portions of the Real Property in accordance
  with the terms and conditions of this Section.

  such emergency actions taken outside the ordinary course of business.

6.4    Further Assurances.
  Subject to the terms and conditions of this Agreement, each Party shall, upon
  request by the other Party at any time, or from time to time, after the Closing,
  and without further consideration, execute and deliver to such other Party such
  other instruments of sale, transfer, conveyance, assignment and confirmation,
  provide such materials and information and take such other actions as such other
  Party may reasonably request in order to consummate the transactions contemplated
  by this Agreement.

6.5    Employee and Employee Benefit
  Matters.

(a)    Schedule 6.5(a) sets forth
  a list of Project Employees that Seller and such Affiliates will make available
  to Purchaser at least thirty (30) Business Days before the Closing Date (the
  "Available Employees") for the purpose of discussing
  potential employment with Purchaser (which discussions the Parties agree shall
  not violate Section 12.5), together with each such Available Employee's
  name, current annual base compensation, job title, work location, hire date,
  vacation balance and sick leave balance, as of the date hereof. Prior to the
  Closing Date, Purchaser may make an offer of employment to any Available Employee,
  and each such offer shall include terms and provisions determined by Purchaser
  that are consistent with the provisions of this Section 6.5; provided,
  that subject to the following provisions of this Section 6.5, the foregoing
  shall not be construed to prevent Purchaser from changing the terms and conditions
  of employment of any Continued Employee (as hereinafter defined) following the
  Closing Date. Seller shall be responsible for, and shall indemnify and hold
  Purchaser harmless from and against, (i) all severance benefits payable under
  Seller's applicable severance policies to any Available Employees (or any other
  employee of Seller or its Affiliates) who do not accept or are not provided
  with an offer of employment with Purchaser or its Affiliates prior to or at
  Closing, and (ii) any accrued salary or incentive compensation or outstanding
  vacation or sick pay balance as of the Closing owing to any employee of Seller
  or its Affiliates, whether or not any such employee is provided with or accepts
  an offer of employment with Purchaser or its Affiliates. Purchaser shall be
  responsible for, and shall indemnify and hold Seller harmless from and against,
  any Losses caused by or resulting from any failure by Purchaser to offer employment
  to any Available Employee on any basis prohibited by ap plicable Law.

(b)    On or before five (5) Business Days
  prior to the Closing Date, Purchaser shall deliver to Seller a Schedule 6.5(b)
  that sets forth the names of the Available Employees who have agreed to accept
  employment with Purchaser effective as of the Closing Date (each, a "Continued
  Employee"); provided, that to be a Continued Employee, such
  employee must (i) accept Purchaser's offer to transfer employment to Purchaser
  under the terms provided in Purchaser's offer, and (ii) on the Closing Date,
  be actively at work, on wellness or sickness leave, short-term disability or
  an approved leave of absence.

(c)    Effective as of the Closing Date,
  the Continued Employees shall cease to participate in all "employee benefit
  plans" (within the meaning of Section 3(3) of ERISA) of Seller or its Affiliates
  (the "Seller Plans"). Purchaser shall not assume any
  of the Seller Plans.

(d)    From and after the Closing Date,
  Purchaser shall cause each Continued Employee to be provided with compensation
  and benefits on a basis substantially similar to those provided to similarly
  situated employees of Purchaser and its Affiliates. Purchaser shall cause each
  Continued Employee and his or her "eligible dependents" (as defined
  by the applicable group health plan of Purchaser or its Affiliates) to be covered
  under a group health plan maintained by Purchaser or an Affiliate of Purchaser
  that (i) provides medical benefits to the Continued Employee and such eligible
  dependents effective immediately upon the Closing Date and (ii) credits such
  Continued Employee and such eligible dependents, for the year during which such
  coverage under such group health plan begins, with any deductibles and co-payments
  already incurred during such year under a group health plan maintained by Seller
  or an Affiliate of Seller (provided, that for purposes of appl ying this
  clause (ii) with respect to any Continued Employee or eligible dependent, the
  Continued Employee or eligible dependent, as applicable, shall be responsible
  for providing the necessary information to Purchaser based on explanation of
  benefit forms received by the Continued Employee or the eligible dependent from
  the group health plan maintained by Seller or an Affiliate of Seller). Purchaser
  shall cause the employee benefit plans and programs maintained after the Closing
  by Purchaser and the Affiliates of Purchaser to recognize each Continued Employee's
  years of service and level of seniority prior to the Closing Date with Seller
  and the Affiliates of Seller for purposes of terms of employment and eligibility
  and vesting under such plans and programs (other than benefit accruals under
  any defined benefit pension plan). Purchaser shall cause each employee welfare
  benefit plan or program sponsored by Purchaser or an Affiliate of Purchaser
  in which the Continued Employees may be eligible to participa te on or after
  the Closing Date to waive any preexisting condition exclusion with respect to
  participation and coverage requirements applicable to Continued Employees and
  their eligible dependents.

(e)    Claims of Continued Employees and
  their eligible beneficiaries and dependents for medical, dental, prescription
  drug, life insurance, or other welfare benefits ("Welfare
  Benefits") (other than disability benefits) that are incurred before
  the Closing Date shall be the responsibility solely of Seller and the Seller
  Plans. Claims of Continued Employees and their eligible beneficiaries and dependents
  for Welfare Benefits (other than disability benefits) that are incurred from
  and after the Closing Date shall be the responsibility solely of Purchaser and
  its Affiliates. For purposes of this paragraph, a medical/dental claim shall
  be considered incurred on the date when the medical/dental services are rendered
  or medical/dental supplies are provided, and not when the condition arose or
  when the course of treatment began. Claims of individuals receiving long-term
  disability benefits under a Seller Plan as of the Closing Date shall be t he
  responsibility solely of Seller and the Seller Plans. Except as provided in
  the preceding sentence, claims of Continued Employees and their eligible beneficiaries
  and dependents for short-term or long-term disability benefits from and after
  the Closing Date shall be the responsibility solely of Purchaser and its Affiliates
  (without regard to whether the circumstances giving rise to such claim occurred
  before, on or after the Closing Date).

(f)    All claims for health care and dependent
  care flexible spending account benefits submitted on or after the Closing Date
  for expenses incurred prior to the Closing Date by Continued Employees shall
  be paid by Seller's or its Affiliates' health care and dependent care flexible
  spending account plan to the extent permitted in accordance with the terms of
  such plan.

(g)    Claims for workers' compensation
  benefits arising out of occurrences prior to the Closing Date shall be the responsibility
  of Seller. Claims for workers' compensation benefits for Continued Employees
  arising out of occurrences on or after the Closing Date shall be the responsibility
  of Purchaser.

6.6    Insurance.Seller
  shall maintain or cause to be maintained the insurance policies (or reasonably
  equivalent renewals or replacements thereof) covering the Project until the
  Closing. Neither Seller nor any of its Affiliates shall have any liability for
  any claims made or reported under such insurance policies after the Closing.

6.7    Seller's Covenants and Closing
  Conditions. Except as contemplated by this Agreement or with the prior
  written consent of Purchaser, during the Interim Period Seller shall use commercially
  reasonable efforts to:

(a)    take all actions that are reasonably
  necessary or appropriate to ensure that the representations and warranties in
  Article IV hereof remain true and correct in all respects at the
  Closing;

(b)    promptly advise Purchaser of any
  facts of which Seller has Knowledge that would cause any of Seller's representations
  and warranties to be untrue or would make the satisfaction of the conditions
  in Article VIII impossible or unlikely; and

(c)    bring about, as soon as practical
  after the date hereof, the satisfaction of all the conditions set forth in Article
  VIII.

6.8    Purchaser's Covenants and
  Closing Conditions. Except as contemplated by this Agreement or with
  the prior written consent of Seller, during the Interim Period Purchaser shall
  use commercially reasonable efforts to:

(a)    take all actions that are reasonably
  necessary or appropriate to ensure that the representations and warranties in
  Article V remain true and correct in all material respects at the Closing;

(b)    promptly advise Seller of any facts
  of which Purchaser has Knowledge that would cause any of Purchaser's representations
  and warranties to be untrue or would make the satisfaction of the conditions
  in Article IX impossible or unlikely; and

(c)    bring about, as soon as practical
  after the date hereof, the satisfaction of all the conditions set forth in Article
  IX.

6.9    Exclusivity. Seller
  covenants that it will not, and will not cause or permit its Affiliates or any
  of their respective Representatives to, directly or indirectly, (a) discuss,
  negotiate, undertake, authorize, recommend, propose or enter into, either as
  the proposed surviving, merged, acquiring or acquired entity, any transaction
  involving a merger, consolidation, business combination, purchase or disposition
  of any of the Purchased Assets or any equity interest in Seller other than the
  transactions contemplated by this Agreement and the Ancillary Agreements (an
  "Acquisition Transaction"), (b) facilitate, encourage,
  solicit or initiate discussions, negotiations or submissions of proposals or
  offers in respect of an Acquisition Transaction, (c) furnish or cause to be
  furnished, to any Person, any information concerning the business, operations,
  properties or Assets of Seller in connection with an Acquisition Transaction,
  or (d ) otherwise cooperate in any way with, or assist or participate in, facilitate
  or encourage, any effort or attempt by any other Person to do or seek any of
  the foregoing; provided, however, that Affiliates of the Seller
  may engage in discussions or negotiations with, or furnish information concerning
  the Seller and its properties, assets and business to, any person which makes,
  or indicates in writing an intention to make, a proposal for an Acquisition
  Transaction if the Board of Directors of such Affiliate shall conclude in good
  faith on the basis of the advice of its outside counsel that the failure to
  take such action would violate the fiduciary obligations of such Board of Directors
  under applicable Law. Seller will inform Purchaser in writing immediately following
  the receipt by Seller, its Affiliates or any Representative of any substantial
  written proposal in respect of any Acquisition Transaction. Notwithstanding
  the foregoing, and without limiting the provisions of Section 6.3 , Seller
  shall be entitled from time to time and at any time prior to the Closing, without
  obligation of or liability to Purchaser, to market, sell and deliver capacity
  and energy products and services from the Project and any portion thereof for
  a term or terms ending not later than the Closing.

6.10    Risk of Loss.

(a)    From the date hereof until the Closing,
  all risk of loss or damage to the property included in the Purchased Assets
  shall be borne by Seller.

(b)    If, before the Closing any or all
  of the Purchased Assets are taken by eminent domain, or are the subject of a
  pending or, to Seller's Knowledge, contemplated taking or condemnation which
  has not been consummated, Seller shall notify Purchaser promptly in writing
  of such fact.

(i)    If such taking would reasonably
  be expected to have a Seller Material Adverse Effect, Purchaser and Seller shall
  negotiate in good faith to settle the loss resulting from such taking or condemnation
  (including by making a fair and equitable adjustment to the Purchase Price)
  and, upon such settlement, consummate the transactions contemplated by this
  Agreement pursuant to the terms of this Agreement. If no such settlement is
  reached within sixty (60) days after Seller has notified Purchaser of such taking
  or condemnation, then Purchaser or Seller may, if such taking relates to the
  Purchased Assets, terminate this Agreement pursuant to Section 10.1(h)
  hereof.

(ii)    If such taking or condemnation
  would not reasonably be expected to have a Seller Material Adverse Effect, Purchaser
  and Seller shall negotiate in good faith to settle the loss resulting from such
  taking or condemnation (including by making a fair and equitable adjustment
  to the Purchase Price or by transferring certain rights to the condemnation
  award, if any, to Purchaser) and, upon such settlement, consummate the transactions
  contemplated by this Agreement pursuant to the terms of this Agreement.

(c)    If, before the Closing, all or any
  material portion of the Purchased Assets are damaged or destroyed by fire or
  other casualty, Seller shall notify Purchaser promptly in writing of such fact.

(i)    If such damage or destruction would
  reasonably be expected to have a Seller Material Adverse Effect and Seller has
  not notified Purchaser of its intention to cure such damage or destruction within
  thirty (30) days after the occurrence of such damage or destruction, Purchaser
  and Seller shall negotiate in good faith to settle the loss resulting from such
  casualty (including by making a fair and equitable adjustment to the Purchase
  Price) and, upon such settlement, consummate the transactions contemplated by
  this Agreement pursuant to the terms of this Agreement. If no such settlement
  is reached within sixty (60) days after Seller has notified Purchaser of such
  casualty, then Purchaser or Seller may terminate this Agreement pursuant to
  Section 10.1(h) hereof.

(ii)    If such damage or destruction would
  not reasonably be expected to have a Seller Material Adverse Effect and Seller
  has not notified Purchaser of its intention to cure such damage or destruction
  within thirty (30) days after the occurrence of such damage or destruction,
  Purchaser and Seller shall negotiate in good faith to settle the loss resulting
  from such casualty (including by making a fair and equitable adjustment to the
  Purchase Price or by transferring certain rights to insurance proceeds, if any,
  to Purchaser) and, upon such settlement, consummate the transactions contemplated
  by this Agreement pursuant to the terms of this Agreement.

(d)    If the Parties fail to reach a settlement
  contemplated by Section 6.10(b)(ii) or Section 6.10(c)(ii) hereof,
  as applicable, within thirty (30) days after Seller has notified Purchaser of
  such taking or casualty, as the case may be, then the Purchase Price shall be
  adjusted downward by the amount of the fair market value of the portion of the
  Purchased Assets subject to the taking, condemnation or casualty loss, as determined
  by Independent Accountants for review and final determination of such fair market
  value. The Independent Accountants may request of Seller or Purchaser such documents
  and information as may be necessary or appropriate for proper determination
  of any such matter, and such Parties will cooperate to promptly satisfy any
  such request. The Independent Accountants shall be instructed to deliver to
  Purchaser and Seller a written determination of the fair market value within
  thirty (30) days from the date of referral thereof to the In dependent Accountants.
  Except in the case of fraud or manifest error, the determination by the Independent
  Accountants of such fair market value will be final and binding on the Parties.
  Seller and Purchaser will equally share the fees and disbursements of the Independent
  Accountants in undertaking such review and determination.

6.11    Current Evidence of Title.

(a)    As soon as is reasonably possible
  after the Agreement Date, and in no event later than thirty (30) Business Days
  after the Agreement Date, Seller shall furnish to Purchaser, for each parcel,
  tract or subdivided land lot of Real Property set forth on Schedule 4.13(a):

(i)    from Stewart Title Guaranty Company
  (the "Title Insurer"):

(A)    title commitments issued by the
  Title Insurer to insure title to all Real Property and Improvements in the amount
  of that portion of the Purchase Price allocated to the Real Property, covering
  such Real Property, naming Purchaser as the proposed insured and having an effective
  date after the Agreement Date, wherein the Title Insurer shall agree to issue,
  an ALTA 1992 form owner's extended coverage policy of title insurance (each
  a "Title Commitment"); and

(B)    complete and legible copies of all
  documents listed or disclosed in Schedule B to the Title Commitment (the "Title
  Exception Documents"); and

(ii)    at Purchaser's cost and expense,
  a survey of the Real Property made after the Agreement Date by a land surveyor
  licensed by the State of Arizona and bearing a certificate, signed and sealed
  by the surveyor, certifying to Seller, Purchaser and the Title Insurer that:

(A)    such survey was made (1) in accordance
  with "Minimum Standard Detail Requirements for ALTA/ACSM Land Title
  Surveys," jointly established and adopted by ALTA and ACSM in 1992,
  and includes Items 1-4, 6, 7(a), 7(b)(1), 7(c), 8-11 and 13 of Table A thereof,
  and (2) pursuant to the Accuracy Standards (as adopted by ALTA and ACSM and
  in effect on the date of said certificate) of an "Urban" survey; and

(B)    such survey reflects the locations
  of all building lines, easements and areas affected by any Title Exception Documents
  affecting such Real Property as disclosed in the Title Commitment (identified
  by issuer, commitment number, and an effective date after the date hereof) as
  well as any encroachments onto the Real Property or by the Improvements onto
  any easement area or adjoining property (each a "Survey");
  and

(iii)    The Title Commitment shall include
  the Title Insurer's standard requirements for issuing its title policy, which
  requirements, to the extent applicable to Seller, shall be met by Seller on
  or before the Closing Date (including those requirements that must be met by
  releasing or satisfying monetary Liens, but excluding requirements that are
  to be met solely by Purchaser).

(iv)    Seller shall pay the premium for
  a standard form owner's policy. Purchaser shall be responsible for the difference
  in premium between standard and extended coverage and for other endorsements
  and any other costs and expenses of such policy of title insurance.

(b)    If any of the following shall occur:

(i)    any Title Commitment or other evidence
  of title or search of the appropriate real estate records discloses that any
  party other than Seller has title to the insured estate covered by the Title
  Commitment;

(ii)    any title exception is disclosed
  in Schedule B to the Title Commitment that (A) is not one of the Permitted
  Liens and (B) Purchaser reasonably believes could have a material adverse effect
  on Purchaser's use and enjoyment of the Real Property described therein; or

(iii)    any Survey discloses any matter
  that Purchaser reasonably believes could have a material adverse effect on Purchaser's
  use and enjoyment of the Real Property described therein;

then Purchaser shall notify Seller in writing ("Purchaser's
  Notice") of such matters (any such matter of which Purchaser so
  provides Purchaser's Notice to Seller, a "Title Objection")
  within thirty (30) Business Days after receiving all of the Title Commitment,
  Survey and copies of Title Exception Documents for the Real Property covered
  thereby. Any such matter of which Purchaser fails to provide Purchaser's Notice
  to Seller within such period shall not constitute a Title Objection and shall
  be deemed to be acceptable to Purchaser and constitute a Permitted Lien for
  purposes of this Agreement.

(c)    Seller shall have ten (10) Business
  Days after receipt of Purchaser's Notice to notify Purchaser that either (i)
  Seller has elected to remove any Title Objection(s) from the title and provide
  Purchaser with evidence reasonably satisfactory to Purchaser of such removal,
  or provide Purchaser with evidence reasonably satisfactory to Purchaser that
  said exceptions will be removed on or before the Closing, or (ii) Seller has
  elected not to remove such Title Objections. Notwithstanding the provisions
  to the contrary contained in this Section 6.11(c), Seller shall remove
  all liens, mortgages, deeds of trust or other monetary liens and encumbrances
  (other than non-delinquent real estate taxes for the current year or special
  assessments or local improvement district assessments payable in installments
  which shall be paid or prorated to the Closing Date as provided in Section
  3.2) prior to or upon Closing. If Seller gives Purchaser notice under the
  foregoin g clause (ii), Purchaser shall have ten (10) Business Days to elect
  to proceed with the purchase and take the Real Property subject to such Title
  Objections (which exceptions shall then constitute Permitted Liens), or to terminate
  this Agreement. If Purchaser shall fail to give Seller written notice of such
  election within said ten (10) Business Days, Purchaser shall be deemed to have
  waived any and all such Title Objections. If Seller shall give notice pursuant
  to the foregoing clause (i), Seller shall use commercially reasonable efforts
  to cure each Title Objection which is the subject of such notice prior to the
  Closing and take all steps required by the Title Insurer to eliminate each Title
  Objection as an exception to the Title Commitment. In the event that Seller
  shall thereafter fail to remove any such Title Objections from title prior to
  the Closing Date, and Purchaser is unwilling to take title subject thereto,
  Purchaser may elect to terminate this Agreement, and in the event of any such
  terminat ion, Seller shall be liable for payment of all title cancellation charges.
  Any Title Objection that the Title Company is willing to insure over on terms
  acceptable to Seller and Purchaser is herein referred to as an "Insured
  Exception." The Insured Exceptions, together with any title exception
  or matters disclosed by the Survey not objected to by Purchaser in the manner
  aforesaid, shall be deemed to be acceptable to Purchaser and shall constitute
  a Permitted Lien for purposes of this Agreement.

(d)    Nothing herein waives Purchaser's
  right to claim a breach of Section 4.13 or to claim a right to indemnification
  as provided in Article XI if Purchaser suffers Losses as a result of
  a misrepresentation with respect to the condition of title to the Real Property.

6.12    Transition Plan. Within
  ten (10) Business Days after the Agreement Date, Purchaser shall deliver to
  Seller a list of its proposed representatives to a joint transition team. Seller
  will add its representatives to such team within five (5) Business Days after
  receipt of Purchaser's list. Such team will be responsible for preparing as
  soon as reasonably practicable after the Agreement Date, and timely implementing,
  a transition plan which will identify and describe substantially all of the
  various transition activities that the Parties will cause to occur before and
  after the Closing and any other transfer of control matters that any Party reasonably
  believes should be addressed in such transition plan. If requested by either
  Party, the terms and conditions governing such transition activities will be
  more fully set forth in a transition agreement reasonably satisfactory to the
  Parties. Purchaser and Seller shall use commercially reasonable eff orts to
  cause their representatives on such transition team to cooperate in good faith
  and take all reasonable steps necessary to develop a mutually acceptable transition
  plan by no later than sixty (60) days after the Agreement Date.

6.13    Updating.

(a)    Each Party shall, from time to time
  prior to the Closing by written notice to the other Party, supplement or amend
  the Schedules to this Agreement to correct any matter that constitutes a breach
  of any representation or warranty made by such Party in Article IV or
  Article V, as the case may be, as of the Agreement Date. In the event
  that at any time either Party supplements or amends any Schedule pursuant to
  this Section 6.13(a), such Party shall: (i) concurrently with a notice
  provided to the other Party containing such supplement or amendment, specifically
  identify and provide a detailed description (including any supporting information,
  materials and data) of the breach such supplement or amendment is proposed to
  cure reasonably sufficient to enable the other Party to make an informed decision
  with respect to the consequences of such b reach and (ii) promptly, and in any
  event within two (2) Business Days of the request of the other Party, provide
  the other Party with any additional information, materials and data relating
  to such breach as may be reasonably requested by the other Party. Provided that
  the foregoing shall have been complied with, any such supplement or amendment
  shall, unless the other Party objects thereto in writing within a period of
  fifteen (15) Business Days after notice of such supplement or amendment, be
  deemed to cure, effective as of the Agreement Date, any applicable inaccuracy
  in such representation or warranty to the extent (and only to the extent) such
  inaccuracy has been specifically detailed as provided above, and to constitute
  a waiver by such other Party of any applicable breach of or default under this
  Agreement. Notwithstanding the foregoing, any such waiver shall not apply to
  the conditions set forth in Section 8.6 or Section 9.6 and no
  retroactive effect shall be given to any such supple ment or amendment for purposes
  of any determination as to the magnitude of, as the case may be, (1) any change
  in the Purchased Assets after the Agreement Date that, individually or in the
  aggregate with other such changes, has, or could reasonably be expected to have,
  a Seller Material Adverse Effect, or (2) any change in the business, assets,
  operations, property, performance or condition (financial or otherwise) of Purchaser
  after the Agreement Date which, individually or in the aggregate with other
  such changes, has, or could reasonably be expected to have, a Purchaser Material
  Adverse Effect. In the event that the other Party does so object in writing,
  the applicable Schedule supplement or amendment made pursuant to this Section
  6.13(a) shall not be deemed to cure any inaccuracy of any representation
  or warranty made in this Agreement by the Party supplementing or amending such
  Schedule, and shall not be considered to constitute or give rise to a waiver
  by the other Party of any condition or obl igation set forth in this Agreement.

(b)    Each Party shall, from time to time
  prior to the Closing by written notice to the other Party, supplement or amend
  the Schedules to this Agreement with respect to any matter arising after the
  Agreement Date that, if existing at, or occurring on, the Agreement Date, would
  have been required to be set forth or described on any such Schedule. In the
  event that at any time either Party supplements or amends any Schedule pursuant
  to this Section 6.13(b), such Party shall: (i) concurrently with a notice
  provided to the other Party containing such supplement or amendment, specifically
  identify and provide a detailed description (including any supporting information,
  materials and data) of the breach such supplement or amendment is proposed to
  cure reasonably sufficient to enable the other Party to make an informed decision
  with respect to the consequences of such breach and (ii) promptly, and in any
  event within two (2) Business Days of the request of the other Party, provide
  the other Party with any additional information, materials and data relating
  to such breach as may be reasonably requested by the other Party. Any such supplement
  or amendment shall, effective immediately upon notice thereof to the other Party,
  be deemed to cure any applicable inaccuracy in such representation or warranty
  to the extent (and only to the extent) such inaccuracy has been specifically
  detailed as provided above, and any applicable breach of or default under this
  Agreement shall be deemed waived; provided that notwithstanding the foregoing,
  the foregoing waiver shall not apply to the conditions set forth in Section
  8.6 or Section 9.6 and no retroactive effect shall be given to any
  such supplement or amendment for purposes of any determination as to the magnitude
  of, as the case may be, (1) any change in the Purchased Assets after the Agreement
  Date that, individually or in the aggregate with other such changes, has, or
  could reasonably be expected to have, a Seller Material Adverse Effect, or (2)
  any change in the business, assets, operations, property, performance or condition
  (financial or otherwise) of Purchaser after the Agreement Date which, individually
  or in the aggregate with other such changes, has, or could reasonably be expected
  to have, a Purchaser Material Adverse Effect. In the event that any Schedule
  to this Agreement is supplemented or amended pursuant to this Section 6.13(b),
  and the matter with respect to which such Schedule is supplemented or amended
  causes or results in an expense, fee or other type of cost to either Party,
  the Parties shall negotiate in good faith to determine how such expense, fee
  or other costs should fairly and reasonably be apportioned between the Parties.
  If the Parties are unable reasonably promptly to agree upon such apportionment
  of such expense, fee or other costs, the Parties' dispute with respect to such
  apportionment shall be resolved in accordance with the arbitration provisions
  of Section 11.6; provided, however, that if the Parties
  are unable reasonably promptly to agree upon such apportionment of such expense,
  fee or other costs, and such expense, fee or other costs must be paid prior
  to the Closing, the Parties shall, pending the Closing, share such expense,
  fee or other costs equally so as not to delay or prevent the Closing, subject
  to reimbursement of any overpayment following resolution of the Parties dispute
  in accordance with the arbitration provisions of Section 11.6.

(c)    Each Party shall notify the other
  Party promptly after becoming aware of any inaccuracy in or breach of any representation
  or warranty of such other Party under this Agreement.

(d)    Without limiting the generality
  of the foregoing, (i) Seller shall notify Purchaser promptly of the occurrence
  of any event which, to Seller's Knowledge, could reasonably be expected to result
  in a Seller Material Adverse Effect, and (ii) Purchaser shall notify Seller
  promptly of the occurrence of any event which, to Purchaser's Knowledge, could
  reasonably be expected to result in a Purchaser Material Adverse Effect.

6.14    Records.

(a)    On the Closing Date or as soon as
  practicable thereafter, Seller shall deliver or cause to be delivered to Purchaser
  all original agreements, documents, Books and Records and files, including records
  and files stored in electronic form (collectively, "Records"),
  if any, in the possession of Seller relating to the Business to the extent not
  then in the possession of Purchaser, provided that (i) Purchaser recognizes
  that certain Records may contain incidental information relating to Affiliates
  of Seller, and that Seller may retain such Records and shall provide copies
  of the relevant portions thereof to Purchaser and (ii) Records shall not include
  (A) documents or files relating to employees who are not Continued Employees
  or (B) employee documents or files afforded confidential treatment under any
  applicable Laws, except to the extent the affected employee consents in writing
  to the disclosure of the same to Purchaser.

(b)    Following the Closing, Purchaser
  shall permit Seller and its Representatives, during normal business hours and
  upon reasonable notice, to have reasonable access to personnel of Purchaser,
  and to examine and make copies of, all Records, in each case relating to transactions
  or events occurring prior to the Closing ("Pre-Closing Transactions")
  or transactions or events occurring subsequent to the Closing that are related
  to or arising out of Pre-Closing Transactions, to the extent such Pre-Closing
  Transactions relate to Excluded Liabilities or Excluded Assets or to the extent
  necessary to comply with applicable financial reporting obligations. Purchaser
  agrees that it shall retain all such Records for a period of seven (7) years
  following the Closing, or for such longer period following the Closing as may
  be required by applicable Law.

6.15    Synthetic Lease Transaction.
  Seller represents and warrants that, pursuant to the terms of an Amended and
  Restated Participation Agreement dated as of July 17, 2001 by and among PPL
  Large Scale Distributed Generation II, LLC, as Lessee and Supervisory Agent,
  Large Scale Distributed Generation II Statutory Trust, a Connecticut statutory
  trust, as Lessor, State Street Bank and Trust Company of Connecticut, National
  Association, as Trustee, First Union National Bank, as Administrative Agent,
  certain financial institutions, as Certificate Holders, and certain financial
  institutions, as Lenders, and various other related agreements, Seller and certain
  of its Affiliates entered into a synthetic lease arrangement (the "Synthetic
  Lease Transaction") for purposes of financing the acquisition and construction

  11.4(b) and 11.4(c)); provided, however, that Seller
  agrees to indemnify, defend and hold harmless the Purchaser Indemnified Parties
  from and against any and all Losses, whether or not involving a third-party
  Claim, resulting from or arising out of or in connection with any such Environmental
  Liabilities or Tort Liabilities that accrue, arise or occur prior to the Closing
  ("Pre-Closing Environmental Liabilities/Tort Liabilities");
  provided, further, that in no event shall Seller's aggregate liability
  arising out of its indemnification obligations f or or with respect to any such
  Pre-Closing Environmental Liabilities/Tort Liabilities exceed the amount of
  $3,500,000 in the aggregate; and provided, further, that Seller's
  indemnification obligations shall extend only to such Pre-Closing Environmental
  Liabilities/Tort Liabilities as are attributable to conditions existing at or
  prior to Closing, and Seller shall not be required to indemnify Purchaser for
  Losses to the extent attributable to acts or omissions of Purchaser resulting
  in any increase or aggravation of such Environmental Liabilities or Tort Liabilities,
  whether arising from a change in use of the Purchased Assets or otherwise. Notwithstanding
  anything to the contrary contained in Section 11.3 or any other provision
  of this Agreement, after the Closing, any assertion by Purchaser or any Purchaser
  Indemnified Party that Seller is liable to Purchaser or any Purchaser Indemnified
  Party for indemnification with respect to Losses for or with respect to any
  Pre-Closing Environment al Liabilities/Tort Liabilities must be made in writing
  and must be given to Seller (or not at all) on or prior to the earlier of the
  fifth anniversary of the Closing Date or the date on which the applicable statute
  of limitations expires with respect to the matters covered thereby.

(d)    The Parties acknowledge that Section
  5 of the Martin Farms Lease provides as follows (with all capitalized terms
  used in the following paragraph having the meaning assigned thereto in the Martin
  Farms Lease):

Lessee, as a material part of the consideration for this Lease,
  hereby agrees to indemnify and hold Lessor entirely free and harmless from all
  liability, responsibility and obligations for any crop loss or damage or other
  loss, damage or injury to any person or property (whether arising during or
  after the lease term) that may arise from (a) Lessee's use of the Premises or
  from the acts or omissions of Lessee or its agents, employees, invitees or contractors,
  or from (b) Lessor's delivery to the Premises and Lessee's use of reuse water
  from the Power Plant or, as to claims brought by, through or on behalf of Lessee
  or persons or entities financing Lessee, any other act or omission of Lessor
  or Lessor's affiliated entities or persons arising from or related to the operation
  of the Power Plant and/or its water supply, treatment, storage, disposal and/or
  reuse systems and operations. The forgoing indemnity shall also apply to any
  and all damages, claims, losses, costs and expenses arising fr om or related
  to the acts or omissions set forth in this paragraph, including without limitation
  any attorneys' fees incurred by Lessor in defending against any such liability.

The Parties further acknowledge that Section 8.3 of the Martin
  Farms Lease provides as follows (with all capitalized terms used in the following
  paragraph having the meaning assigned thereto in the Martin Farms Lease):

Lessee agrees to indemnify and hold Lessor harmless from any
  and all claims, damages, fines, judgments, penalties, costs, liabilities or
  losses (including, without limitation, any and all sums paid for settlement
  of claims, attorneys' fees, consultant and expert fees) arising during or after
  the term of this Lease from or in connection with the presence of hazardous
  substances and/or contaminants in or on the Premises as the result of Lessee's
  actions or inactions, or those of its agents, invitees, employees or assigns,
  unless the hazardous substances are present solely as a result of the negligence,
  willful misconduct or other wrongful acts of the Lessor's agents, employees,
  contractors or invitees. This indemnification shall specifically include any
  and all costs due to hazardous substances that flow, diffuse, migrate or percolate
  into, onto or under the Premises after the Lease terminates. As used herein,
  "hazardous substance" means any substance that is toxic, ignitable,
  re active or corrosive, or is defined and/or regulated as "hazardous waste,"
  "extremely hazardous waste," or "hazardous substance" pursuant
  to state, federal or local governmental law.

(The indemnity obligations set forth above in this Section
  11.1(d) are hereinafter referred to collectively as the "Martin
  Farms Indemnity Obligations"). Without limiting any other provision
  of this Article XI, Purchaser agrees that, in the event that (i) the
  Martin Farms Lease is, in accordance with the intent of the Parties, included
  among the Transferred Contracts sold, assigned, conveyed, transferred and delivered
  by Seller to Purchaser pursuant to Section 2.1 of this Agreement, and
  (ii) at any time from and after the Closing Seller incurs any Claim by or Loss
  to Purchaser under Article XI of this Agreement for or in respect of
  any Losses that, in Seller's reasonable determination, fall within the scope
  of the Martin Farms Indemnity Obligations, Purchaser shall, promptly upon any
  request by Seller, assign, transfer and convey to Seller all right, title and
  interest of Purchaser for and with respect to any rights, claims and causes
  of action available under the Martin Farms Indemnity Obligations. In the event
  that Purchaser is not reasonably capable of effecting any such assignment, transfer
  and conveyance, or in the event that any such assignment, transfer or conveyance
  does not, in Seller's reasonable determination, provide Seller with a complete
  and effective remedy and right of action against the lessee under the Martin
  Farms Lease for or in respect of the Martin Farms Indemnity Obligations, Purchaser
  shall, upon any request by Seller and at Seller's sole cost and expense, actively
  and diligently pursue against the lessee under the Martin Farms Lease, for and
  on behalf of Seller, any and all Claims that are reasonably available to Purchaser
  under the Martin Farms Indemnity Obligations for or in respect of any such Losses.
  The legal counsel employed in any such action shall be selected by Seller in
  its sole discretion, and the fees and expenses of such counsel shall be paid
  exclusively by Seller. Purchaser shall cooperate fully wit h Seller and such
  counsel in the defense or compromise of such Claim, and in such event that Purchaser
  provides such cooperation no compromise or settlement of such Claims may be
  effected by Seller without Purchaser's consent unless there is not in connection
  therewith any finding or admission of any violation of Law or any violation
  of the rights of any Person by Purchaser. Purchaser covenants and agrees that
  it will not, without the prior consent of Seller, permit or agree to any amendment
  of the Martin Farms Lease that eliminates or in any way reduces the benefits
  and protections afforded by the Martin Farms Indemnity Obligations to the lessor
  under the Martin Farms Lease.

11.2    Waiver of Remedies.

(a)    The Parties hereby agree to limit
  their recourse for all matters, and not make any Claim for any Loss or other
  matter, under, relating to or arising out of this Agreement or any other document,
  agreement, certificate or other matter delivered pursuant hereto, whether based
  on contract, tort, strict liability, other Laws or otherwise, except (i) for
  Claims for indemnification pursuant to this Article XI , (ii) as permitted
  in Article X, or (iii) as permitted under Section 12.15 (Attorneys'
  Fees). From and after the Closing, the indemnification provisions of this Article
  XI shall be the sole and exclusive remedy of each Party (including the Seller
  Indemnified Parties and Purchaser Indemnified Parties) (i) for any breach of
  the other Party's representations, warranties or covenants contained in this
  Agreement or (ii) otherwise with respect to this Agree ment or the transactions
  contemplated hereby.

(b)    NOTWITHSTANDING ANYTHING TO THE
  CONTRARY CONTAINED IN THIS AGREEMENT, UNDER NO CIRCUMSTANCES SHALL ANY PARTY
  BE LIABLE UNDER OR IN CONNECTION WITH THIS AGREEMENT FOR SPECIAL, PUNITIVE,
  EXEMPLARY, INCIDENTAL, CONSEQUENTIAL OR INDIRECT DAMAGES, OR LOST PROFITS, WHETHER
  BASED ON CONTRACT, TORT, STRICT LIABILITY, OTHER LAW OR OTHERWISE AND WHETHER
  OR NOT ARISING FROM SUCH PARTY'S SOLE, JOINT OR CONCURRENT NEGLIGENCE, STRICT
  LIABILITY OR OTHER FAULT ("Non-reimbursable Damages").

(c)    Notwithstanding anything to the
  contrary contained in this Agreement, no Representative of Seller, Affiliate
  of Seller or Representative of any such Affiliate shall, except as provided
  in the Guaranty Agreement, have any personal liability to Purchaser or any other
  Person as a result of the breach of any representation, warranty, covenant or
  agreement of Seller contained herein and no Representative of Purchaser, Affiliate
  of Purchaser or Representative of any such Affiliate shall have any personal
  liability to Seller or any other Person as a result of the breach of any representation,
  warranty, covenant or agreement of Purchaser contained herein.

11.3    Survival and Time Limitation.
  The terms and provisions of this Agreement shall survive the Closing. Notwithstanding
  the foregoing, after the Closing, any assertion by Purchaser or any Purchaser
  Indemnified Party that Seller is liable to Purchaser or any Purchaser Indemnified
  Party for indemnification under the terms of this Agreement or otherwise in
  connection with the transactions contemplated in this Agreement must be made
  in writing and must be given to Seller (or not at all) on or prior to the date
  that is twenty-four (24) months after the Closing Date, except for (i) indemnification
  for breach of Seller's representations and covenants in Sections 4.10,
  4.13(a), 4.14, 4.21, 6.5, 6.15 and 7.1, which shall
  survive for the limitations period provided under applicable Law, and (ii) indemnification
  for matters addressed in Section 11.1(a)(iii) or (iv), which must
  be made in writing and must be given to Seller (or not at all) on or prior to
  the date that is ninety (90) days after the date on which the applicable statute
  of limitations expires with respect to the matters covered thereby.

11.4    Waiver of Other Representations;
  Limitations of Liability.

(a)    NOTWITHSTANDING ANYTHING TO THE
  CONTRARY CONTAINED IN THIS AGREEMENT, IT IS THE EXPRESS INTENT OF EACH PARTY
  HERETO THAT NEITHER PARTY IS MAKING ANY REPRESENTATION OR WARRANTY WHATSOEVER,
  EXPRESS OR IMPLIED, EXCEPT FOR THOSE REPRESENTATIONS AND WARRANTIES CONTAINED
  IN ARTICLE IV AND ARTICLE V, RESPECTIVELY, AND THAT, EXCEPT FOR SUCH EXPRESS
  REPRESENTATIONS AND WARRANTIES, PURCHASER IS ACQUIRING THE PURCHASED ASSETS
  "AS IS" AND "WHERE IS." WITHOUT LIMITING THE GENERALITY
  OF THE FOREGOING, SELLER HEREBY EXPRESSLY DISCLAIMS ANY OTHER REPRESENTATION
  OR WARRANTY OF ANY KIND, INCLUDING ANY IMPLIED REPRESENTATION OR WARRANTY AS
  TO CONDITION, MERCHANTABILITY OR SUITABILITY FOR ANY PARTICULAR PURPOSE AS TO
  ANY OF THE PURCHASED ASSETS AND SELLER MAKES NO REPRESENTATION OR WARRANTY TO
  PURCHASER WITH RESPECT TO ANY FINANCIAL PROJECTION OR FORECAST RELATING TO THE
  PURCHASED ASSETS. WITH RESPECT TO ANY SUCH PROJECTION OR FORECAST DELIVERED
  BY OR ON BEHALF OF SELLER TO PURCHASER, PURCHASER ACKNOWLEDGES THAT (I) THERE
  ARE UNCERTAINTIES INHERENT IN ATTEMPTING TO MAKE SUCH PROJECTIONS AND FORECASTS,
  (II) IT IS FAMILIAR WITH SUCH UNCERTAINTIES, AND (III) IT HAS MADE ITS OWN EVALUATION
  OF THE ADEQUACY AND ACCURACY OF ALL SUCH PROJECTIONS AND FORECASTS FURNISHED
  TO IT.

(b)    Notwithstanding anything to the
  contrary contained in this Agreement, (i) Seller shall have no liability for
  its indemnification obligations under Section 11.1(a)(i) or Section
  11.1(a)(ii) until the aggregate amount of all Losses incurred by the Purchaser
  Indemnified Parties equals or exceeds $1,000,000 (the "Threshold
  Amount"), in which event Seller shall be liable for all such Losses
  from dollar one; it being understood and agreed that the foregoing Threshold
  Amount shall not apply to (A) claims for indemnification relating to Excluded
  Liabilities, and (B) claims for indemnifications relating to Sections 3.2,
  4.10, 4.13(a), 4.14, 4.21, 6.5, 6.15 and 7.1,
  in each case for which Seller shall be responsible from dollar one, whether
  or not the Threshold Amount has been reached and (ii) Purchaser shall have no
  liability for its indemnification obligations under Section 11.1(b)(i)
  or S ection 11.1(b)(ii) until the aggregate amount of all Losses incurred
  by the Seller Indemnified Parties equals or exceeds the Threshold Amount, in
  which event Purchaser shall be liable for all such Losses from dollar one; it
  being understood and agreed that the foregoing Threshold Amount shall not apply
  to (A) claims for indemnification relating to Assumed Liabilities, and (B) claims
  for indemnification relating to Sections 3.2, 6.5 and 7.1, in
  each case for which Purchaser shall be responsible from dollar one, whether
  or not the Threshold Amount has been reached; and

(c)    In no event shall (i) Seller's aggregate
  liability arising out of its indemnification obligations under Section 11.1(a)(i)
  and Section 11.1(a)(ii) exceed 50% of the Purchase Price; it being understood
  and agreed that the foregoing limitation shall not apply to claims for indemnification
  relating to Excluded Liabilities and any indemnifiable Losses related to such
  Excluded Liabilities shall not be deemed to count against or otherwise reduce
  such limitation on Seller's aggregate liability and (ii) Purchaser's aggregate
  liability arising out of its indemnification obligations under Section 11.1(b)(i)
  and Section 11.1(b)(ii) exceed 50% of the Purchase Price; it being understood
  and agreed that the foregoing limitation shall not apply to claims for indemnification
  relating to Assumed Liabilities and any indemnifiable Losses related to such
  Assumed Liabilities shall not be deemed to count against or otherwise reduce
  such limitation on Purcha ser's aggregate liability.

11.5    Procedure for Indemnification
  - Third-Party Claims.

(a)    If any Party shall claim indemnification
  hereunder arising from any Claim of a third party, the Party seeking indemnification
  (the "Indemnified Party") shall notify in writing the
  Party from which indemnification is sought (the "Indemnifying Party")
  of the basis for such Claim, setting forth the nature of the Claim in reasonable
  detail. The failure of the Indemnified Party to so notify the Indemnifying Party
  shall not relieve the Indemnifying Party of any indemnification obligation hereunder
  except to the extent that the defense of such Claim is materially prejudiced
  by the failure to give such notice.

(b)    If any proceeding is brought by
  a third party against an Indemnified Party and the Indemnified Party gives notice
  to the Indemnifying Party pursuant to Section 11.5(a), the Indemnifying
  Party shall be entitled to participate in such proceeding and, to the extent
  that it wishes, to assume the defense of such proceeding, if (i) the Indemnifying
  Party provides written notice to the Indemnified Party that the Indemnifying
  Party intends to undertake such defense, (ii) the Indemnifying Party conducts
  the defense of the third-party Claim actively and diligently with counsel reasonably
  satisfactory to the Indemnified Party and (iii) if the Indemnifying Party is
  a party to the proceeding, the Indemnifying Party has not determined in good
  faith that joint representation would be inappropriate because of a conflict
  in interest. The Indemnified Party shall, in its sole discretion, have the right
  to employ separate counsel (who may be selected by the Indemnified Party in
  its sole discretion) in any such action and to participate in the defense thereof,
  and the fees and expenses of such counsel shall be paid by such Indemnified
  Party. The Indemnified Party shall fully cooperate with the Indemnifying Party
  and its counsel in the defense or compromise of such Claim. If the Indemnifying
  Party assumes the defense of a proceeding, no compromise or settlement of such
  Claims may be effected by the Indemnifying Party without the Indemnified Party's
  consent unless (A) there is no finding or admission of any violation of Law
  or any violation of the rights of any Person and no effect on any other Claims
  that may be made against the Indemnified Party and (B) the sole relief provided
  is monetary damages that are paid in full by the Indemnifying Party.

(c)    If (i) the Indemnified Party gives
  notice to the Indemnifying Party of the commencement of any third-party legal
  proceeding and the Indemnifying Party does not, within ten (10) days after the
  Indemnified Party's notice is given, give notice to the Indemnified Party of
  the Indemnifying Party's election to assume the defense of such legal proceeding,
  (ii) any of the conditions set forth in clauses (i) through (iii) of Section
  11.5(b) above become unsatisfied or (iii) an Indemnified Party determines
  in good faith that there is a reasonable probability that a legal proceeding
  may adversely affect it other than as a result of monetary damages for which
  it would be entitled to indemnification from the Indemnifying Party under this
  Agreement, the Indemnified Party shall (upon notice to the Indemnifying Party)
  have the right to undertake the defense, compromise or settlement of such claim;
  provided that the Indemnifying Party shall reimburse the Indemnified
  Party for the Indemnified Party's costs of defending against the third-party
  claim (including reasonable attorneys' fees and expenses) and the Indemnifying
  Party shall remain responsible for any indemnifiable amounts arising from or
  related to such third-party claim to the fullest extent provided in this Article
  XI. The Indemnifying Party may elect to participate in such legal proceedings,
  negotiations or defense at any time at its own expense.

11.6    Arbitration.

(a)    Any and all disputes between the
  Parties arising out of or relating to this Agreement (a "Dispute")
  must be resolved through the use of binding arbitration using three (3) arbitrators,
  selected in accordance with the Commercial Arbitration Rules of the American
  Arbitration Association ("AAA") as then in effect, as
  supplemented to the extent necessary to determine any procedural appeal questions
  by the Federal Arbitration Act (Title 9 of the United States Code), and shall
  be administered by AAA. If there is any inconsistency between this Section
  11.6 and the Commercial Arbitration Rules or the Federal Arbitration Act,
  the terms of this Section 11.6 will control the rights and obligations
  of the Parties. If there is more than one (1) Arbitrable Dispute that involves
  the same facts and parties as the facts and parties with respect to which an
  arbitration has been initiated pursuant to this Agreement, such disputes shall
  be consolidated into the first arbitration initiated pursuant to this Agreement.
  No other arbitration shall be consolidated with any arbitration initiated pursuant
  to this Agreement without the agreement of the Parties or parties thereto. The
  Party initiating any Dispute must promptly notify AAA in writing of any such
  action.

(b)    Arbitration must be initiated within
  the applicable time limits set forth in this Agreement and not thereafter or
  if no time limit is given, within the time period allowed by the applicable
  statute of limitations. Arbitration may be initiated by either Seller or Purchaser
  ("Claimant") serving written notice on Purchaser or
  Seller, respectively ("Respondent") that Claimant elects
  to refer the Dispute to binding arbitration (the "Arbitrable Dispute").

(c)    Claimant's notice initiating binding
  arbitration must describe in reasonable detail the nature of the Arbitrable
  Dispute and the facts and circumstances relating thereto and identify the arbitrator
  Claimant has appointed. Respondent shall respond to Claimant within sixty (60)
  days after receipt of Claimant's notice, identifying the arbitrator Respondent
  has appointed. If Respondent fails for any reason to name an arbitrator within
  such sixty (60) day period, Claimant may upon notice to the AAA and the Respondent,
  request that the AAA office in Phoenix, Arizona select the Respondent's arbitrator,
  with the AAA giving due regard to the selection criteria set forth below and
  input from the Respondent in making such selection. The two (2) arbitrators
  so chosen shall select a third arbitrator within thirty (30) days after the
  second arbitrator has been appointed. If the two (2) arbitrators are unable
  to agree on a third arbitrator within such thirty (30) day select ion period,
  then either Party may, upon notice to the AAA and the other Party, request that
  the AAA office in Phoenix, Arizona select the third arbitrator, with the AAA
  giving due regard to the selection criteria set forth below and input from the
  Parties and other arbitrators in making such selection.

(d)    The AAA shall select the third arbitrator
  not later than thirty (30) days from the notice of request sent to the AAA in
  accordance with Section 11.6(c) above. In the event the AAA should fail
  to select the third arbitrator within such thirty (30) day period, then either
  Party may petition the Chief United States District Judge for the State of Arizona
  to select the third arbitrator. The Party making such petition shall provide
  a copy thereof to the other Party. The Chief Judge shall give due regard to
  the selection criteria set forth below and input from the Parties and other
  arbitrators in making such selection.

(e)    Subject to the arbitrators' award
  of costs to the prevailing party, Claimant shall pay the compensation and expenses
  of the arbitrator named by or for it, Respondent shall pay the compensation
  and expenses of the arbitrator named by or for it, and Claimant and Respondent
  shall each pay one-half (1/2) of the compensation and expenses of the third
  arbitrator. All arbitrators must be neutral parties who have never been officers,
  directors or employees of the Parties or any of their Affiliates. Each of the
  three (3) arbitrators must have not less than seven (7) years experience as
  an attorney or accountant handling complex business transactions and have formal
  training in dispute resolution.

(f)    The hearing will be conducted in
  Phoenix, Arizona, and commence within sixty (60) days after the selection of
  the third arbitrator. The Parties and the arbitrators should proceed diligently
  and in good faith in order that the award may be made as promptly as possible.
  The arbitrators shall determine the Arbitrable Disputes of the Parties and render
  a final award in accordance with the choice of Law set forth in this Agreement.
  The arbitrators shall render their decision within sixty (60) days following
  completion of the hearing. The arbitrators' decision shall be in writing and
  set forth the reasons for the award and shall include an award of costs to the
  prevailing Party (or an allocation of such costs between the Parties based upon
  the extent to which each prevails), including reasonable attorneys' fees and
  disbursements and the fees and expenses of the arbitrators. All statutes of
  limitations and defenses based upon passage of time applicable to any Arbit
  rable Dispute (including any counterclaim or setoff) shall be interrupted by
  the filing of the arbitration and suspended while the arbitration is pending.
  The terms of this Section 11.6 shall not create nor limit any obligations
  of a Party hereunder to defend, indemnify or hold harmless the other Party against
  Claims or Losses. In order to prevent irreparable harm, the arbitrators shall
  have the power to grant temporary or permanent injunctive or other equitable
  relief. A Party may, notwithstanding any other provision of this Agreement,
  seek temporary injunctive relief or other interim, provisional or interlocutory
  relief or any order in aid of arbitration from any court of competent jurisdiction;
  provided, that the Party seeking such relief shall (if arbitration has
  not already been commenced) simultaneously commence arbitration. Such court-ordered
  relief shall not continue more than ten (10) days after the appointment of the
  third arbitrator and in no event for longer than sixty (60) days . Except as
  provided in the Federal Arbitration Act, the decision of the arbitrators will
  be binding on and non-appealable by the Parties. Each Party agrees that any
  arbitration award against it may be enforced in any court of competent jurisdiction
  and that any Party may authorize any such court to enter judgment on the arbitrators'
  decisions. The arbitrators may not grant or award Non-reimbursable Damages.

12.2    Entire Agreement.
  This Agreement and the Ancillary Agreements supersede all prior discussions,
  agreements and understandings between the Parties with respect to the subject
  matter hereof and thereof and contain the sole and entire agreement between
  the Parties with respect to the subject matter hereof and thereof. As of the
  execution of this Agreement by the Parties, the Confidentiality Agreement between

  replaced, merged in and superseded by this Agreement and the Ancillary Agreements

  matter of such agreement and that occurred prior to the Agreement Date.

12.3    Expenses. Except
  as otherwise expressly provided in this Agreement, whether or not the transactions

  transactions contemplated hereby.

12.4    Public Announcements.
  Except as may be required by Law or any applicable stock exchange rules, neither
  Party will issue or make any press releases or other public disclosures concerning
  this Agreement or the transactions contemplated hereby without first obtaining
  consent from the other Party, which consent shall not be unreasonably withheld,
  conditioned or delayed.

12.5    Confidential Information.

(a)    For a period of two (2) years from
  and after the Closing, Seller shall cause any data or information received at
  any time by Seller or its Affiliates or its or their Representatives from Purchaser,
  any data or information regarding Purchaser or its businesses, operations, financial
  conditions or prospects, and any data or information regarding the Purchase
  Price and other key financial terms of the transactions contemplated hereby
  and the discussions among the Parties relating thereto (any of the foregoing,
  "Purchaser Information"), to be maintained by Seller,
  its Affiliates and their respective Representatives in confidence, not to be
  utilized for any purpose (except, pending Closing, to prepare therefor) and
  not to be disclosed for any purpose. Without limiting the generality of the
  foregoing, Seller and Purchaser acknowledge that, during the Interim Period,
  Purchaser may conduct one or more solicitations or requests for proposals from
  third parties and that the foregoing restrictions concerning the Purchase Price
  and other financial terms are necessary in order to protect Purchaser's interest
  in the integrity of its acquisition activities.

(b)    From the Agreement Date until the
  Closing (or, if this Agreement is earlier terminated, then until two (2) years
  after the date of such termination, and in any event, in the case of any Seller
  Information not contained in the Purchased Assets, from the Agreement Date until
  a period two (2) years from and after the Closing), Purchaser shall cause any
  such data or information received at any time by Purchaser, its Affiliates or
  their respective Representatives from Seller, its Affiliates or their respective
  Representatives and any such data or information regarding Seller or its businesses,
  operations, financial conditions or prospects, and any data or information regarding
  the Purchase Price and other key financial terms of the transactions contemplated
  hereby and the discussions among the Parties relating thereto (any of the foregoing,
  "Seller Information"), to be maintained by Purchaser,
  its Affiliates and their respective Representatives in confidence, not to be
  utilized for any purposes (except pending Closing, to prepare therefor) and
  not to be disclosed for any purpose.

(c)    Purchaser and Seller acknowledge
  that the approvals of the Governmental Authorities that are required by this
  Agreement will likely necessitate the provision of Confidential Information
  to third parties in proceedings to obtain such approvals. Where a filing is
  made with any Governmental Authority for approval of this Agreement, the Party
  responsible for the filing shall request that the Governmental Authority approve
  a reasonable confidentiality agreement or protective order that will provide
  appropriate protections for any Confidential Information of the other Party.

(d)    Other than as provided in Section
  12.5(c) and with respect to the obligations under Sections 12.5(a)
  and 12.5(b), in the event that the Party receiving Confidential Information
  (the "Receiving Party") is requested by any Governmental
  Authority to disclose any Confidential Information of the other Party (the "Disclosing
  Party"), the Receiving Party shall give the Disclosing Party prompt
  written notice of such requirement and shall not disclose any such Confidential
  Information without reasonable assurances from such Governmental Authority that
  such Confidential Information will be afforded reasonable confidentiality protections
  by such Governmental Authority. In the event that the Receiving Party becomes
  legally compelled (by deposition, interrogatory, request for documents, subpoena,
  civil investigative demand or similar process) to disclose any Confidential
  Information (or, in the case of any such disclosure to the ACC, the Receiving
  Party is required or requested to make such disclosure as a condition to the
  approval by the ACC contemplated by Section 8.7(b)), the Receiving Party
  shall give the Disclosing Party prompt written notice of such requirement so
  that the Disclosing Party may attempt to seek a protective order or other assurance
  that confidential treatment will be accorded to any such portion of such Confidential
  Information as may be required to be disclosed (and the Receiving Party shall
  cooperate reasonably with any such efforts by the Disclosing Party) or waive
  compliance with the terms of this Section 12.5. In the event that such
  protective order or other remedy is not timely obtained, the Receiving Party
  agrees to give the Disclosing Party written notice of the Confidential Information
