        the  part of PNM and do not,  and  will  not,  require  the  consent  or
        approval  of the  stockholders  of PNM or any  trustee  or holder of any
        indebtedness  or other  obligation  of PNM,  other than (i) the Mortgage
        Release, (ii) the finding of the ANPP Administrative Committee described

        have been or on or before the Closing Date will have been duly  executed
        and delivered by PNM, and this Participation Agreement constitutes,  and
        upon execution and delivery thereof,  each such Transaction Document and
        each such  Financing  Document  will  constitute,  the legal,  valid and
        binding  agreement of PNM,  enforceable  against it in  accordance  with
        their respective terms.

                (4) No  Violation,  etc.  Neither  the  execution,  delivery  or
        performance by the Lessee of this  Participation  Agreement or any other
        Transaction  Document to which it is, or is to become,  a party, nor the
        consummation by the Lessee of the  transactions  contemplated  hereby or
        thereby,  nor  compliance  by the Lessee with the  provisions  hereof or
        thereof,  conflicts or will conflict with, or results or. will result in

        to perform its  obligations  under this  Participation  Agreement or any

        governmental body which questions the validity or enforceability of this
        Participation  Agreement or any other Transaction  Document to which the
        Lessee is, or is to become,  a party,  or  (except as  described  in the
        reports to which  reference  is made in the last  sentence of  paragraph
        (12)  above)  which,  individually  or  in  the  aggregate,  if  decided
        adversely to the interests of the Lessee,  would have a material adverse
        effect on the business or financial  condition of PNM or materially  and

        Governmental Action or other authorization,  license,  approval, permit,
        consent,  right or  interest,  where a  failure  to  obtain  such  would
        materially  and  adversely  affect  the  ability  of PNM to carry on its
        business as presently conducted.

                (18) No Default,  etc.  PNM is not in default,  and no condition
        exists that,  with the giving of notice or lapse of time or both,  would
        constitute a default by PNM,  under the  Existing  Mortgage or any other
        material mortgage,  deed of trust,  indenture,  lease, contract or other
        instrument or agreement to which PNM is a party or by which it or any of
        its properties or assets may be bound.

                (19)  Certain  Documents.  True and  correct  copies of the ANPP
        Participation  Agreement,  the Material Project  Agreements  (other than
        those referred to in clauses (x) through (xiv) of the definition of such
        term,  true and  correct  copies  of which  will be  delivered  promptly
        following  the  closing  Date)  and  the  Existing  Mortgage  have  been
        delivered to Milbank,  Tweed, Hadley & McCloy. No ANPP Project Agreement
        will, on and after the Closing Date,  materially and adversely interfere
        with (i) (except for the ANPP  Participation  Agreement,  in the case of
        the Generation Entitlement Share only) the title of the Owner Trustee to
        the Undivided Interest,  the related Generation Entitlement Share or the
        Real.  Property  Interest  or (ii)  except  for the  ANPP  Participation
        Agreement,  the use of,  or the  exercise  by the Owner  Trustee  of its
        rights under the Facility Lease,  the Deed, the Assignment of Beneficial
        Interest  and  the  Assignment  and  Assumption  with  respect  to,  the
        Undivided  Interest,  the related Generation  Entitlement Share, and the
        interests  in the PVNGS  Site  (including  the Real  Property  Interest)
        granted or to be granted  under the Deed,  the  Assignment of Beneficial
        Interest and the Assignment and Assumption.. No payment default or other
        default  of a  material  nature  by  the  Lessee  has  occurred  and  is
        continuing  under the Existing  Mortgage or any ANPP Project  Agreement.
        The ANPP  Participation  Agreement and each other ANPP Project Agreement
        is in full  force  and  effect  and no  breach  of any  thereof,  to the
        Lessee's  knowledge,  by any other  party  thereto has  occurred  and is
        continuing,  except  where the failure to be in force and effect or such
        breach  would not have a material  and adverse  effect on the  Undivided
        Interest,  the related  Generation  Entitlement Share, the Real Property
        interest,  Unit 2 or the  rights,  interests  and  benefits of the Owner
        Trustee or the Owner  Participant under any Transaction  Document.  Upon
        execution  and  delivery of the  Mortgage  Release  and the  recordation
        thereof or of UCC releases in respect  thereof,  (i) the  mortgagee  and



                                      -34-

        secured  party  thereunder  will have  released the lien of the Existing
        Mortgage on the Undivided Interest,  the related Generation  Entitlement
        Share and the Real  Property  Interest  and (ii) the rights of the Owner
        Trustee in the Undivided Interest and the Real Property Interest and the
        related  Generation  Entitlement Share will not be, and will not become,
        subject or subordinate to the rights of any Person, except the Indenture
        Trustee under the Indenture and the ANPP Participants  under, and to the
        extent expressly set forth in, the ANPP  Participation  Agreement (as in
        effect on the closing  Date) and except as may  otherwise  expressly  be
        permitted by the Facility Lease. The lien of the Existing  Mortgage does
        not extend to rights of PNM under the Transaction  Documents (other than
        the Lessee's  leasehold  interest under the Facility  Lease),  or to the
        Generation Entitlement Share related to the Undivided Interest.  Neither
        the Owner  Trustee  nor the Owner  Participant  shall,  by virtue of the
        transactions   contemplated   by  the   Transaction   Documents,   be  a
        "Transferee" under Section 15.10 of the ANPP Participation Agreement.

                (20) Unit 2. The description of Unit 2 set forth in Exhibit B to
        the Bill of Sale, as delivered on the closing Date,  will be correct and
        sufficiently complete to identify such property.

                (21) Investment Company Act. PNM is not an "investment company",
        or a company "controlled" by an "investment company", within the meaning
        of the Investment company Act.

                (b)     Agreements.

                (1)  Delivery  of  Documents.  The  Lessee  agrees  that it will

        case of Sections 10(b) (1) (iii) and (v), the Owner Trustee):

                shall give notice  thereof to the rating  agencies  specified in
                such  paragraphs,  such notice to be  sufficiently in advance of

                   (viii) ANPP Project  Agreements.  Except where the failure to
                do so would  not  have a  material  and  adverse  effect  on the
                Undivided  Interest,  the Real Property Interest,  Unit 2 or the
                rights, interests and benefits of the Owner Trustee or the Owner

                impairment thereof, (4) enforce the ANPP Participation Agreement
                in accordance  with its terms and (5) not take,  fail to take or
                join in (i) any action  with  respect  to, nor accept or approve
                any  amendment  or any other  change in, the ANPP  Participation
                Agreement or any other ANPP Project Agreement or (ii) any action
                or change the effect of which  would be to relieve the Lessee of
                any  obligation  under the ANPP  Participation  Agreement  on or
                after the Closing  Date.  The Lessee will not,  unless the Owner
                Participant otherwise consents,  accept or approve any amendment
                to any ANPP  Project  Agreement  the effect of which would be to

                transaction  or (y)  any  present  or  future  ANPP  Participant
                because such ANPP Participant  derived or will derive its status
                as "Participant"  under the ANPP Participation  Agreement from a
                lessor in a sale and leaseback  transaction,  or (D) deprive the
                owner Trustee or the Owner  Participant,  as the case may be, of
                the  benefit  of  Sections  15.2.2,  15.10  and 32.1 of the ANPP
                Participation    Agreement   (or   any   comparable    successor
                provisions). The Lessee shall (X) provide copies of any proposed
                amendment to or modification of the ANPP Participation Agreement
                to the  Owner  Participant  not less  than 45 days  prior to the
                execution  thereof  by the  Lessee  (except  where the Lessee is
                unaware thereof 45 days prior to such  execution,  in which case
                the Lessee shall provide  notice thereof as promptly as possible
                after becoming so aware) and (Y) upon such execution  furnish to
                the  Owner   Participant  a  copy  of  any  such   amendment  or
                modification  as  executed.  The  Lessee  will  not,  except  as
                permitted by paragraph  (ii) above,  sell,  transfer,  assign or
                otherwise dispose of, except in the ordinary course of operation
                of PVNGS, all or any of its rights or interests in and to PVNGS.

                except in connection  with the selection of Bonds for redemption
                pursuant  to the  Collateral  Trust  Indenture,  the Bonds.  The
                Lessee  agrees  that (1)  neither  it nor any of its  Affiliates
                shall  purchase  any Bond more than 180 days in  advance  of the
                date  of  the  mandatory  sinking  fund  redemption   applicable
                thereto,  (2)  the  aggregate  of  Bonds  of any one  series  so
                purchased  shall not exceed the amount of the,  next  succeeding
                sinking  fund  payment  applicable  thereto and (3) any Bonds so
                purchased  shall  be the  subject  of a  request  by the  Lessee
                pursuant  to  the   provisions  of  the   commitment   agreement
                applicable to such series of Bonds.

                      (x) Cooperation.  The Lessee will cooperate with the Owner
                Participant  and the Owner  Trustee in  obtaining  the valid and
                effective  issue,  or, as the case may be, transfer or amendment
                of all Governmental Actions (including,  but without limitation,
                the  License)   necessary  or,  in  the  opinion  of  the  Owner
                Participant,   desirable  for  the   ownership,   operation  and
                possession  of the  Undivided  Interest  (including  the related
                Generation Entitlement Share), the Real Property Interest or any
                portion of Unit 2  represented  thereby by the Owner  Trustee or
                any transferee,  lessee or assignee  thereof for the period from

                obligations under Applicable Law concerning the  Decommissioning
                of Unit 2. If Applicable Law or  Governmental  Action shall not,
                on or before  December  31,  1990,  impose  upon the  Lessee the
                obligation  to create and  maintain  an  external  reserve  fund
                (which may be a fund which  qualifies  under Section 468A of the
                Code) dedicated to paying all Decommissioning  Costs relating to
                the Undivided Interest, then the Lessee will create and maintain
                such  a fund  on  terms  reasonably  satisfactory  to the  Owner



                                      -46-

                Participant;  if  Applicable  Law or  Governmental  Action shall
                thereafter  impose upon the Lessee an  obligation  to create and
                maintain such a fund, any fund in compliance with Applicable Law
                or such Governmental  Action shall be deemed satisfactory to the
                Owner  Participant for purposes of the preceding  sentence.  (B)
                Except to the extent  provided in clauses (C) and (D) below,  as
                between the Lessee, the Owner Trustee, the Owner Participant and
                any transferee (including by way of lease) or assignee of any of
                the Lessor's or the Owner Participant's right, title or interest
                in Unit 2, the Lessee agrees to pay, or cause to be paid, and to
                indemnify  such  parties  against,  all  Decommissioning  Costs,

                Date, any Event of Default,  Default, Event of Loss, Deemed Loss
                Event or any other event or  occurrence,  (ii) any  provision of
                any  Transaction  Document,  or other  document,  instrument  or
                agreement, including the ANPP Participation Agreement, (iii) any
                provision of the License or any other license or permit, or (iv)
                any Applicable Law,  charter or by-law  provision,  Governmental
                Action or other impediment,  including,  without limitation, the
                bankruptcy or insolvency of the Lessee,  either now or hereafter
                in  effect;  it being  understood  that the  obligations  of the
                Lessee  under  this  clause  (B) are and shall be  a~so1ute  and
                unconditional.  (C) In the  event  that (i) the  Facility  Lease
                shall  have  expired  upon  expiration  (or  early   termination
                pursuant to Section  14(e) of the  Facility  Lease) of the Lease
                Term (other  than in  connection  with an Event of Loss,  Deemed
                Loss Event or Event of Default) and (ii)  thereafter  the Lessor
                shall (I) re-lease the  Undivided  Interest to any Person or (2)
                retain the Undivided Interest and sell power and energy from its
                Generation Entitlement Share, then after the Lessor has received
                (x) in the case of clause (1) above, gross rents in an aggregate
                amount (when discounted back to such Lease Termination Date at a
                rate per annum equal to the Prime Rate) equal to 20% of Facility
                Cost,  or (y) in the case of  clause  (2)  above,  net  electric

                revenues in an  aggregate  amount  (discounted  as I  aforesaid)
                equal to 20% of  Facility  Cost,  the  Lessor  shall  thereafter
                reimburse the Lessee for any expenditures incurred by the Lessee
                under  clauses (A) and (B) of this Section  10(b) (3) (xi) in an
                amount equal to any further rent  received or proceeds  received
                from the sale of power and energy to the  extent  that such rent
                or proceeds are attributable to the  decommissioning  obligation
                of the Lessee under this Section  10(b) (3) (xi) with respect to
                the period from and after such Lease  Termination  Date (payable
                on an annual basis with respect to each year or portion  thereof
                during the term of such lease referred to in clause (1) above or
                such  period  referred to in clause (2) above  during  which the
                Lessor retains the Undivided Interest);  provided, however, that
                when such  amount has been paid the Lessor  shall be relieved of
                all obligations to make further  reimbursement to the Lessee for
                such purpose. (D) In the event that (i) the Facility Lease shall
                have expired upon the expiration (or early termination  pursuant
                to Section 14(e) of the Facility Lease) of the Lease Term (other
                than in  connection  with an Event of Loss1 Deemed Loss Event or

                shall be adjusted to reflect  inflation  or  deflation  from the

                specified  in such  request)  into an  amendment to the Facility
                Lease as necessary to incorporate  therein (in  substitution for
                the definitions of such terms theretofore  appended thereto) and

                following  three  alternatives:  (I) the  definitions of "Deemed

                forth in clause (2) of the  definition  of "Deemed  Loss  Event"
                contained  in Appendix A hereto,  in each case as appended to or
                contained in the Facility Lease entered into in connection  with

                events  similar  to those  contained  in any of the  definitions
                referred to above. In connection  with any such  amendment,  the
                Owner  Participant  shall  submit  (subject  to  review  by  the
                Lessee's  financial  advisors) new Schedules of Special Casualty
                Values and/or  casualty  Values,  in each case calculated on the
                same  assumption  as the  comparable  schedules  appended to the
                Subject  Lease.  In  connection  with any such  amendment,  such
                substituted definitions shall include and be subject to, mutatis
                mutandis,  the same  qualifications and waivers and incorporate,
                mutatis  mutandis,  the same definitions as shall be provided in
                the Subject Lease or related transaction  documents with respect
                to any of the  definitions  referred  to  above  which  shall be
                substituted.

                Lessee,  the Lessee (if permitted by Applicable Law and the ANPP
                Participation  Agreement)  will  enter  into  amendments  to the
                Transaction   Documents  as  necessary  to  reflect   reasonable
                alternative  arrangements  with  respect  to the  Real  Property

        effect to an assumed 11% increase in the Basic Rent  (excluding any Rent
        Differential)  which would have been  payable on the Basic Rent  Payment

Owner Trustee in accordance with Section 5 of the Facility Lease,  except to the
extent expressly  provided in any Transaction  Document,  the ANPP Participation
Agreement or any other agreement or undertaking of the Lessee, (2) for any Claim
against such Indemnitee  resulting  solely from acts which would  constitute the
willful  misconduct or gross  negligence of such  Indemnitee  (unless imputed to
such Indemnitee by reason of Unit 2, the Undivided  Interest,  the Real Property
Interest, PVNGS, the PVNGS Site or any other facilities at the PVNGS Site or any
occurrence in connection with any thereof or by reason of any act or omission of
the Lessee,  whether as agent for such  Indemnitee  or  otherwise),  (3) for any
Transaction Expense to be paid by the Owner Trustee pursuant to Section 14(a) or
(4) for any Claim  resulting  solely from a transfer by the Owner Trustee or the

for  use  therein.   To  the  extent  that  an   Indemnitee   in  fact  receives
indemnification payments from the Lessee under the indemnification provisions of
this  Section  13(a),  the  Lessee  shall be  subrogated,  to the extent of such
indemnity paid, to such  Indemnitee's  rights with respect to the transaction or
event  requiring  or  giving  rise to such  indemnity,  but only so long as such
subrogation shall not materially  adversely affect the rights of such Indemnitee
or any other Indemnitee  hereunder.  Nothing herein or elsewhere contained shall
be  construed  as  constituting  a guaranty by the Lessee of the  principal  of,
premium,  if any, or interest on the Notes or the Bonds or of the residual value
or useful life of the Undivided Interest.

                (b)      General Tax Indemnity.

6091.BURNMAM.1106.27:1



                (1) Indemnity. All payments by the Lessee in connection with the
        transactions  contemplated by the Transaction Documents shall be free of
        expense to each  Indemnitee for  collection or other  charges.  All such
        payments shall be free of withholdings of any nature  whatsoever (and at
        the time that the Lessee is required to make any payment  upon which any
        withholding is required,  the Lessee shall pay an additional amount such
        that the net amount actually  received by the Person entitled to receive
        such payment will, after such withholding,  equal the full amount of the
        payment  then due).  If, for any reason,  the Lessee is required to make
        any payment to a taxing  authority  with  respect to, or as a result of,
        any  withholding  tax  imposed  on  any  Indemnitee  in  respect  of the
        transactions   contemplated   by  the   Transaction   Documents,   which
        withholding  tax is not the  responsibility  of the  Lessee  under  this
        Section 13(b) as  determined  pursuant to this Section 13(b) but without
        regard to the immediately  preceding  sentence of this Section 13(b)(l),
        then such  Indemnitee  shall pay to the Lessee on an After-Tax  Basis an
        amount which equals the amount paid by the Lessee with respect to, or as
        a  result  of,  such   withholding  tax.  Whether  or  not  any  of  the
        transactions contemplated hereby are consummated,  except as provided in
        Section 13(b)(2)1 the Lessee shall pay, and shall indemnify,  defend and
        hold each Indemnitee harmless,  on an After-Tax Basis, from and against,
        any and all Taxes howsoever  imposed (whether imposed on or with respect
        to the Indemnitee,  the Lessee, Unit 2, the Undivided Interest, the Real
        Property Interest, any Capital Improvement or the PVNGS Site or any part
        thereof or interest therein or otherwise) by any Federal, state or local

        foreign or international taxing authority in connection with or relating
        to (A)  the  design,  construction,  financing,  purchase,  acquisition,

        title, rebuilding, rental, importation, exportation or other application
        or  disposition  of, or the  imposition  of any Lien  other  than  Owner
        Participant's  Liens and Owner  Trustee's  Liens (or  incurrence  of any

        with the transactions  contemplated by this Participation Agreement, any
        other Transaction Document or any Financing Document.

                (2)  Exclusions from General Tax Indemnity.  Section 13(b)(l)
(except  for the  first  two sentences thereof) shall not apply to:

                      (i) Taxes based on, or measured by, net income  imposed by
                the  United  States  federal  government   (including,   without
                limitation,  any minimum Taxes, capital gains Taxes, withholding

                or subdivision thereof or by any foreign or international taxing
                authority  that are based on, or  measured  by, the net  income,

                such  Taxes,  except,  with  respect to the Owner  Trustee,  the
                Trust, the Trust Estate, the Owner Participant and any Affiliate
                of any thereof,  any such Taxes imposed by a  jurisdiction  as a
                result of a relation or asserted  relation of such  jurisdiction
                to the transactions contemplated by the Transaction Documents or
                the Financing  Documents or as a result of the activities of the
                Lessee,  any ANPP Participant or any Affiliate of any thereof in
                such  jurisdiction;  provided,  however,  that the amount of any
                such excepted Taxes shall be calculated (i) on a pro forma basis
                assuming that such  Indemnitee  has no other  taxable  income or
                loss in the taxing jurisdiction  imposing the Tax (provided that
                such  calculation  shall take into  account  any  allocation  or
                apportionment  method  used by such  jurisdiction  except to the
                extent  that  such  method  takes  into  account  the  income or
                activities  of business  entities  organized  outside the United
                States)  and is able to use any net  operating  loss  carryovers
                based  on such  pro  forma  calculation  to the  fullest  extent
                allowed  by law and  (ii) by  taking  into  account  any  actual
                reduction  in  Taxes in any  other  jurisdiction  in which  such
                Indemnitee  is subject to tax (whether  such  reduction  results
                from the operation of allocation or apportionment formulas, from
                credits  or  otherwise)   which   reduction   results  from  the
                transactions  contemplated by the  Transaction  Documents or the
                Financing  Documents;  provided  further,  however,  that,  with
                respect  to any Tax based on, or  measured  by,  capital  or net
                worth,  the Lessee's  indemnity  obligation shall not exceed the
                incremental portion of such Tax attributable to the transactions
                contemplated by the Transaction Documents;

                        (iii) Taxes that are imposed  with respect to any period
                after (a) the Lease Termination Date and (b) the date possession
                of the  Undivided  Interest and the Real  Property  Interest has
                been  delivered to the Lessor as provided in Section 5(a) of the
                Facility Lease, but excluding the Agency Period,  if any, unless
                such Taxes relate to events  occurring or matters  arising prior
                to or simultaneously with such date;

                from any voluntary  transfer by such  Indemnitee of any interest
                in the Undivided Interest, the Real Property Interest, the Trust

                or similar  proceeding  in which such  Indemnitee  is the debtor
                unless  such  bankruptcy  or other  proceeding  was  caused by a
                Default  or Event of  Default  by the  Lessee  or an  Affiliate.
                thereof;

                      (v) Taxes based on or measured by any fees,  commission or
                compensation received by an Indemnitee for acting as trustee, or
                for  other  services  rendered,  in  connection  with any of the
                transactions  contemplated by the  Transaction  Documents or the
                Financing Documents;

                      (vi) Taxes on or with respect to an Indemnitee  arising by
                reason of such  Indemnitee's  failure to file  proper and timely
                reports or returns (unless the filing of such reports or returns
                is the obligation of the Lessee under the Transaction  Documents
                or the  Financing  Documents)  and any penalties or additions to
                tax  imposed  by reason of such  Indemnitee's  failure to comply
                with  the laws  imposing  such Tax or its  material  failure  to
                comply with its obligations under Section 13(b)(6),  unless such
                failure  results from any action of the Lessee or failure by the
                Lessee to comply with any provision of the Transaction Documents
                or the  Financing  Documents,  including  the failure to provide
                necessary information;

                      (vii) Taxes on or with respect to an Indemnitee arising as
                a result of a material failure of such Indemnitee to fulfill its
                obligations  with  respect  to  the  contest  of  any  claim  in
                accordance   with   Section   l3(b)(4)  of  this   Participation
                Agreement;

                      (viii)  Taxes  imposed on or with  respect to a transferee
                (or subsequent transferee) of an original Indemnitee (other than
                a  transferee  or  subsequent  transferee  either of which is an
                Affiliate  of the  original  Indemnitee)  to the extent that the
                amount of such Taxes exceeds the amount of taxes that would have
                been imposed on or with respect to such original  Indemnitee but
                for the transfer to such  transferee  or, if imposed,  would not
                have been subject to  indemnification  under this Section 13(b);
                provided,  however,  that the exception in this clause shall not
                apply to any transferee  where such transfer shall have occurred
                during the continuance of an Event of Default:

                      (ix)  any  Taxes  imposed  on  the  Lessor  or  the  Owner
                Participant resulting from, or which would not have occurred but
                for, Lessor's Liens or Owner  Participant's  Liens and any Taxes
                imposed on the  Indenture  Trustee which would not have occurred
                but for Indenture Trustee's Liens;

                      (x) any Tax that results  solely from the activities of an
                Indemnitee  in any  taxing  jurisdiction  which  activities  are
                unrelated to the  transactions  contemplated  by the Transaction
                Documents or the Financing Documents:

                      (xi) any Tax on or with respect to an Indemnitee resulting
                from  any  amendment  or  modification   entered  into  by  such
                Indemnitee to any Transaction  Document or Financing Document if
                the Lessee is not a party to such amendment or  modification  or
                has not  consented to such  amendment or  modification,  in each
                case  unless an Event of  Default  shall  have  occurred  and be
                continuing; and


                                      -75-

6091.BURNHAM.1106.27:l



                      (xii)  any  Tax  on  or  with  respect  to  an  Indemnitee
                resulting  from the gross  negligence  or willful  misconduct of
                such  Indemnitee  (it being  understood  that no  Indemnitee  is
                responsible for determining whether a Tax is payable if such Tax
                is the responsibility of the Lessee under this Section 13(b)).

provided,  however,  that the  foregoing  subdauses  (i) through (xii) shall not
apply to any Tax imposed on the Loan  Participant or the indenture  estate under
the Collateral Trust Indenture.

                (3)  Calculation  of  General  Tax  Indemnity  Payments.  If any
        Indemnitee realizes a net permanent tax benefit by reason of the payment
        of any indemnity under Section  13(b)(l),  such Indemnitee shall pay the
        Lessee,  but  not  before  the  Lessee  shall  have  made  all  payments
        theretofore  due to such  Indemnitee  pursuant to this Section 13(b), an
        amount  equal to the lesser of (x) the sum of such tax benefit  plus any
        other net tax benefit  realized by such  Indemnitee as the result of any
        payment made by such Indemnitee pursuant to this sentence (determined in
        a manner  consistent with the definition of After Tax Basis set forth in
        Appendix A and with the last sentence of Section 13(b)(6)  hereof),  and
        (y) the amount of such payment by the Lessee to such  Indemnitee and any
        other payment by the Lessee to such Indemnitee theretofore made pursuant
        to this Section 13(b) less the aggregate amount of all prior payments by
        such  Indemnitee to the Lessee  pursuant to this clause (y) with respect
        to amounts paid pursuant to Section 13(b)(l),  it being intended that no
        Indemnitee  should  realize a net tax benefit  pursuant to this  Section
        13(b)  unless  the  Lessee  shall  first  have been  made  whole for any
        payments  by it to  such  Indemnitee  pursuant  to this  Section  13(b);
        provided,  however,  that in computing any  permanent tax benefit,  such
        Indemnitee  shall be deemed first to have  utilized all  deductions  and
        credits  available to it otherwise  than by reason of any payment by the
        Lessee pursuant to this Section 13(b);  provided further,  however, that
        notwithstanding the provisions of this clause (3), such Indemnitee shall
        not be  obligated  to make any  payment to the Lessee  pursuant  to this
        clause (3) if at the time such payment  shall be due an Event of Default
        shall have occurred and be continuing.

                (4) General Tax Indemnity Contests.  If a written claim shall be
        made  against  any  Indemnitee  for any  Tax for  which  the  Lessee  is
        obligated  pursuant to this Section 13(b),  such Indemnitee shall notify
        the Lessee  promptly  of such  claim,  but the  failure so to notify the
        Lessee shall not affect any  obligation  of the Lessee  pursuant to this
        Section 13(b) except as provided in Section 13(b)(2)(vii). If the Lessee
        shall  request in writing  within 30 days after  receipt of such notice,
        such Indemnitee  shall in good faith and at the Lessee's expense contest
        the imposition (including the amount) of such Taxes; provided,  however,
        that such  Indemnitee  may in its sole  discretion  select the forum for
        such  contest and  determine  whether any such  contest  shall be by (A)
        resisting  payment of such Taxes, (B) paying such Taxes under protest or
        (C) paying such Taxes and seeking a refund  thereof;  provided  further,
        however,  that (W) such Indemnitee shall not be obligated to contest any
        claim in which the amount in question is less than $125,000, (X) at such
        Indemnitee's  option,  such contest  shall be conducted by the Lessee in
        the name of such Indemnitee  (subject to the preceding  proviso) and (Y)
        in no event shall such Indemnitee be required or the Lessee permitted to
        contest the  imposition  of any Taxes for which the Lessee is  obligated
        pursuant  to this  Section  13(b)  unless  (u)  the  Lessee  shall  have
        acknowledged  its liability to such Indemnitee for an indemnity  payment
        pursuant to this  Section  13(b) as a result of such claim if and to the
        extent  such  Indemnitee  or the Lessee,  as the case may be,  shall not
        prevail in the contest of such  claim;  (v) such  Indemnitee  shall have
        received from the Lessee (i)  satisfactory  indemnity for any liability,
        expense or loss  arising out of or relating to such  contest  including,
        but  not  limited  to,  (A)  all  reasonable  legal,   accountants'  and
        investigatory fees and  disbursements,  (B) the amount of. any interest,
        additions  to  tax or  penalty  that  may  be  payable  as a  result  of
        contesting  such claim and (C) if such contest is to be initiated by the
        payment of, and the claiming of a refund for such Tax,  sufficient funds
        to make  such  payment  on an After Tax  Basis  and (ii) an  opinion  of
        independent  tax  counsel  selected  by the Lessee and  approved by such
        Indemnitee  (which  approval  shall not be  unreasonably  withheld)  and
        furnished at the  Lessee's  sole expense to the effect that a Reasonable
        Basis  exists for  contesting  such claim or, in the event of an appeal,
        that there exists a substantial possibility that an appellate


                                      -77-

6091.BURNHAM.ll06.27:1





       court or an  administrative  agency with appellate  jurisdiction,  as the
       case  may  be,  will   reverse  or   substantially   modify  the  adverse
       determination; (w) the Lessee shall have agreed to pay such Indemnitee on
       demand all reasonable  costs and expenses that such  Indemnitee may incur
       in connection with contesting such claim (including,  without limitation,
       all  costs,  expenses,  losses,  reasonable  legal and  accounting  fees,
       disbursements,  penalties,  interest  and  additions  to  tax);  (x) such
       Indemnitee  shall have reasonably  determined that the action to be taken
       will not  result  in any  danger of sale,  forfeiture  or loss of, or the
       creation of any Lien (except if the Lessee shall have  adequately  bonded
       such Lien or otherwise  made  provision to protect the  interests of such
       Indemnitee in a manner  satisfactory to such  Indemnitee) on, Unit 2, any
       part thereof, the Undivided Interest,  the Real Property Interest, or any
       interest  in any of the  foregoing;  and (y) if  such  contest  shall  be
       conducted  in a manner  requiring  the  payment of the claim,  the Lessee
       shall  have paid the  amount  required.  The  Lessee  agrees to give such
       Indemnitee  reasonable  notice of any contest  prior to the  commencement
       thereof.  If any  Indemnitee  shall obtain a refund of all or any part of
       any Taxes paid by the Lessee,  or if any such refund  would be payable to
       the  Indemnitee  in the  absence  of an  offsetting  liability  for Taxes
       payable to the taxing  authority in question,  such Indemnitee  shall pay
       the  Lessee,  but not  before the  Lessee  shall  have made all  payments
       theretofore  due to such  Indemnitee  pursuant to this Section 13 (b), an
       amount  equal to the lesser of (xx) the amount of such refund so received
       or receivable, including interest received or receivable and attributable
       thereto,  plus any net permanent tax benefit  realized by such Indemnitee
       (determined in a manner consistent with the definition of After Tax Basis
       set forth in Appendix A and with the last  sentence  of Section  13(b)(6)
       hereof) as a result of any payment by such  Indemnitee  made  pursuant to
       this  sentence  (after  taking into account the tax  consequences  of the
       receipt of such refund and such interest) or (yy) such tax payment by the
       Lessee to such  Indemnitee  plus any other  payment by the Lessee to such
       Indemnitee  theretofore  made pursuant to this Section  13(b),  in either
       case,  net of any  expenses  not already  paid or incurred by the Lessee;
       


                                      -78-

6091.BURNHAM.1106.27:1




        provided,  however,  that in computing any tax benefit,  such Indemnitee
        shall be  deemed  first to have  utilized  all  deductions  and  credits
        available  to it  otherwise  than by reason of any payment by the Lessee
        pursuant  to  this  Section  13(b);  provided,  further,  however,  that
        notwithstanding the provisions of this clause (4), such Indemnitee shall
        not be  obligated  to make any  payment to the Lessee  pursuant  to this
        clause  (4) if at the  time  such  payment  shall  be due a  Default  or
        an-Event of Default  shall have  occurred  and be  continuing  under the
        Facility Lease. An Indemnitee  shall not be required to make any payment
        pursuant to this  clause (4) before  such time as the Lessee  shall have
        made all  payments  and  indemnities  then  due  under  the  Transaction
        Documents to such Indemnitee. Notwithstanding anything contained in this
        clause (4) to the contrary,  no Indemnitee  shall be required to contest
        any claim if the subject matter thereof shall be of a continuing  nature
        and  shall  have  previously  been  decided   pursuant  to  the  contest
        provisions  of this clause (4) unless  there shall have been a change in
        the law  (including,  without  limitation,  amendments  to  statutes  or
        regulations,  administrative  rulings  and court  decisions)  after such
        claim shall have been so previously  decided,  and such Indemnitee shall
        have  received an opinion of  independent  tax  counsel  selected by the
        Lessee and  approved by such  Indemnitee  (which  approval  shall not be
        unreasonably withheld) and furnished at the Lessee's sole expense to the
        effect that such change  provides a  Reasonable  Basis for the  position
        which such  Indemnitee and the Lessee,  as the case may be, had asserted
        in such previous contest or for an alternative  position based upon such
        change that the Lessee now desires to assert.  Nothing contained in this
        Section  13(b)  shall  require any  Indemnitee  to contest or permit the
        Lessee to  contest  a claim  which it would  otherwise  be  required  to
        contest  pursuant to this Section 13(b) if such  Indemnitee  shall waive
        payment by the Lessee of any amount that might  otherwise  be payable by
        the Lessee  under this  Section  13(b) by way of indemnity in respect of
        such claim.

                (5)  General Tax  indemnity  Reports.  If any report,  return or
        statement is required to be filed with respect to any obligations of the
        Lessee  under or arising out of this  Section  13(b),  the Lessee  shall
        timely file the same,  except for any such  report,  return or statement
        which such Indemnitee has notified the Lessee that it intends to file.

                                      -79-
6091.BURNHAM.ll06.27:l





       The Lessee shall  either file such  report,  return or statement so as to
       show  the  ownership  of the  Undivided  Interest  or the  Real  Property
       Interest,  as the case may be,  in the Owner  Trustee  and send a copy of
       such report, return or statement to the Owner Trustee and such Indemnitee
       or, where not so permitted,  notify the Owner Trustee and such Indemnitee
       of such  requirement  and  prepare  and deliver  such  report1  return or
       statement  to  the  Owner  Trustee  and  such   Indemnitee  in  a  manner
       satisfactory to the Owner Trustee and such Indemnitee within a reasonable
       time prior to the time such  report,  return or  statement is to be filed
       or, where such  return,  statement or report shall be required to reflect
       items in addition to any  obligations  of the Lessee under or arising out
       of this Section 13(b), provide the Owner Trustee and such Indemnitee with
       information  sufficient  to  permit  such  return,  statement  or  report
       properly to be made with respect to any  obligations  of the Lessee under
       or arising  out of this  Section  13(b)  (and the Lessee  shall hold each
       Indemnitee  harmless  from  and  against  any  liabilities,  obligations,
       losses, damages,  penalties,  claims, actions, suits and reasonable costs
       arising  out of any  insufficiency  or  inaccuracy  in any  such  return,
       statement, report or information). The Lessee shall not have any right to
       examine the tax returns of any Indemnitee.

                (6) General Tax Indemnity-Payment.  All Taxes shall be paid when
        due and payable  (except with respect to Arizona  real  property  taxes,
        which shall be paid before they become delinquent) and, unless otherwise
        requested by the appropriate Indemnitee,  the Lessee shall pay any Taxes
        for which it is liable  pursuant to this Section  13(b)  directly to the
        appropriate  taxing authority and shall pay such appropriate  Indemnitee
        promptly on demand in  immediately  available  funds any amount due such
        Indemnitee  pursuant to this  Section  13(b) with respect to such Taxes.
        Any such demand shall specify in  reasonable  detail the payment and the
        facts upon which the right to payment is based.  Each  Indemnitee  shall
        promptly forward to the Lessee any notice, bill or advice received by it
        concerning any Taxes.  Within 30. days after the date of each payment by
        the  Lessee of any Taxes,  the  Lessee  shall  furnish  the  appropriate
        Indemnitee  the  original  or a  certified  copy  of a  receipt  for the
        


                                      -80-

6091.BURNHAM.1106.27:1




        Lessee's payment of such Taxes or such other evidence of payment of such
        Taxes as is acceptable to such Indemnitee. The Lessee shall also furnish
        promptly upon request such data as any  Indemnitee may require to enable
        such   Indemnitee  to  comply  with  the   requirements  of  any  taxing
        jurisdiction.  Whenever  any  payment is to be made by the Lessee  under
        this Section 13(b) and it shall be necessary,  in calculating  the After
        Tax Basis amount of such payment, to compute the amount of any liability
        for federal, state or local tax imposed on or measured by the net income
        of any  Indemnitee,  such  computation  shall be based on the assumption
        that such taxes shall be payable at the highest marginal  statutory rate
        in effect for the relevant period.

                (7)  Definition  of  Indemnitee.  For  purposes of this  Section
        13(b),  the term  Indemnitee  shall mean and include the  successors and
        assigns  of each  respective  Indemnitee,  and for  purposes  of federal
        income  taxes,  the  affiliated  group of  corporations  and each member
        thereof  (within the meaning of Section  1504 of the Code) of which such
        Indemnitee is a member,  if such group shall file a consolidated  United
        States  federal  income  tax  return,  and,  for  purposes  of income or
        franchise   taxes  imposed  by  a  particular   state  or  16ca1  taxing
        jurisdiction,  shall mean and include any  consolidated or combine group
        of which such Indemnitee is or shall be a member that is treated as such
        by such state or local taxing jurisdiction.

                  (c) Supporting Material.  Each Indemnitee shall provide to the
Lessee such  supporting  material  (other than tax  returns) as the Lessee shall
reasonably  request in connection  with the matters set forth in Section  13(b).
The Lessee shall reimburse to any Indemnitee any expenses  incurred in providing
requested supporting material to the Lessee.

                (d) Cooperation. The Owner Participant shall cooperate and shall
cause the Owner Trustee to cooperate with and consider in good faith any request
by, the  Lessee,  upon the  written  request  and at the  expense  (including  a
reasonable  allowance for internal legal costs) of the Lessee, in order to avoid
or minimize any taxes for which the Lessee is  responsible  under  Section 13(b)
hereof.

                SECTION 14. Transaction Expenses.

                (a)  Transaction   Expenses.   Subject  to  the  pro-visions  of

Trustee  hereby agrees that it will pay when due an  appropriate  portion of the
following costs and expenses (Transaction Expenses):

                      (i) the reasonable  legal fees and  disbursements of Mudge

                Participant),  Milbank,  Tweed,  Hadley  &  Mccloy,  Shearman  &

                notwithstanding such transfer; and

                      (iii) such transfer  shall not violate the  Securities Act

                transferring  Owner  Participant or the Transferee is a party or
                by which its property is bound.

Upon  any  transfer  permitted  pursuant  to  the  foregoing   provisions,   the
transferring  Owner Participant  shall,  except as expressly  provided in clause
(ii) above, be released from its obligations under this Participation  Agreement
and the other Transaction  Documents (including,  without limitation,  the Trust
Agreement) to the extent of the interest  transferred.  An agreement to transfer
shall not in and of itself  constitute  a transfer  for purposes of this Section
15.

                (b)  Procedure.  If the Owner  Participant  transfers all or any
part of its  interest  hereunder  pursuant  to this  Section  15, it shall  give
written notice thereof to the Lessee,  the Owner Trustee,  the Indenture Trustee
and the Loan  Participant,  specifying  the name and  address for notices to the
Transferee,  such  other  information  and  evidence  as shall be  necessary  to
establish  compliance  with  this  Section  15 and the  extent  of the  interest
transferred  to such  Transferee.  If,  as a result  of any such  transfer,  the
original Owner Participant is not to continue to receive all payments to be made
by the Indenture  Trustee to the "Owner  Participant"  under the Indenture,  the
original Owner  Participant  shall from time to time, by notice to the Indenture
Trustee,  with copies to the Lessee,  the Owner Trustee and the Collateral Trust
Trustee,  designate  the  manner  in  which  any  such  payments  to the  "Owner
Participant" are to be allocated, and the Indenture Trustee shall be entitled to
rely on such  notice for all  purposes.  This  Section 15 (other than the notice
provisions  contained in the first  sentence of this  Section  15(c)) is for the
benefit of the Lessee,  the Owner Trustee and the Owner  Participant and may not
be enforced by any other party hereto. The Owner Participant agrees that it will
use reasonable  efforts to provide (or cause to be provided) such information as
the Lessee  may  reasonably  request to comply  with  requests  for  information
received from the NRC with respect to the  Transferee  (provided  that the Owner
Participant  shall not be  required  to provide  (or cause to be  provided)  any
information of a confidential or proprietary nature).

Participant  pursuant to Section 14, the Lessee will indemnify and hold harmless
the Loan  Participant,  the Indenture  Trustee,  the Owner Trustee and the Owner
Participant in respect of any commissions,  fees, judgments or other expenses of
any nature and kind which any of them may become  liable to pay by reason of any
claims by or on behalf of  brokers,  finders,  agents,  advisors  or  investment
bankers in connection with the transactions  contemplated by this  Participation
Agreement,  any other  Transaction  Document or any Financing  Document,  or any
litigation or similar  proceeding arising from any such claim, other than claims
arising out of written undertakings of the party claiming  indemnification under
this  Section  16  or  any  Affiliate  or  shareholder  (or  Affiliate  of  such
shareholder)  of such Person with any such  broker,  finder,  agent,  advisor or
investment banker.

contained in this Participation Agreement, in any other Transaction Document, in
any Financing Document and in any agreement,  document or certificate  delivered

referred to herein,  any disposition of any interest in the Undivided  Interest,
Unit 2 or any other property referred to in this Participation Agreement and the
expiration or other termination of any of the Transaction Documents or Financing
Documents  and  shall  be  and  continue  in  effect   notwithstanding  (i)  any
investigation  made by the Owner Participant or the Loan Participant or (ii) the
fact that any of the Indenture Trustee,  the Owner Trustee, the Loan Participant
or the Owner  Participant  may  waive  compliance  with any of the other  terms,
provisions  or  conditions  of any of the  Transaction  Documents  or  Financing
Documents.  The  obligations  of the Lessee under  Sections 10(b) (2), 10(b) (3)
(vii) , 10(b) (3) (x)  l0(b)(3)(xi),  13,  14, 16 and 19(f)  shall  survive  the

Transaction  Document or  Financing  Document.  The  modification  by law of any
statute of limitations, or the waiver or extension of any statute of limitations

                  (b)  Binding  Effect.  All  agreements,   representations  and
warranties in this Participation  Agreement, the other Transaction Documents and
the Financing Documents and in any agreement,  document or certificate delivered

sentence, each Indemnitee and its successors and assigns. The obligations of the
Lessee  under  Section  13  hereof  and  Section  20 of the  Facility  Lease are
expressly made for the benefit of, and shall be enforce-able by, any Indemnitee,
separately or together,  without  declaring the Facility  Lease to be in default
and notwithstanding any assignment by the Lessor of the Facility Lease or any of
its rights  thereunder or any  disposition of all or any part of any interest in
the Undivided Interest, the Real Property Interest, Unit 2 or any other property
referred to in this Participation  Agreement,  or in any Transaction Document or
any Financing Document.  All payments required to be made pursuant to Section 13
shall be made directly to, or as otherwise requested by, the Indemnitee entitled
thereto upon written demand by such Indemnitee.  The Lessee shall not assign any
of its rights or obligations  hereunder without the prior written consent of the
Owner  Participant  and the Owner Trustee.  Except as otherwise  indicated,  all
references  herein to any party to this  Participation  Agreement  and the other
Transaction Documents shall include the permitted successors and assigns of such
party.

communication or notice.

                  SECTION 19. Miscellaneous.

                (a) Execution.  This Participation  Agreement may be executed in
any number of  counterparts  and by the  different  parties  hereto on  separate
counterparts,  each of  which,  when so  executed  and  delivered,  shall  be an
original,  but all such counterparts  shall together  constitute but one and the
same instrument.  Although this Participation  Agreement is dated as of the date
first above written for convenience, the actual dates of execution hereof by the
parties hereto are respectively the dates set forth under the signatures hereto,
and this Participation Agreement shall be effective on the latest of such dates.

                  (b) Intention of the Owner Trustee and the Owner  Participant.
Each of the Owner  Trustee and the Owner  Participant  intends to  exercise  its
rights and carry out its obligations  hereunder and under the other  Transaction
Documents  solely with a view to furthering  its own best interests and does not
have,  and does not expect to have,  any form of joint  profit  motive  with any
other Person.  The Owner Trustee and the Owner Participant shall not be required
to share any Rent to which they are entitled  under the Facility  Lease,  or the
residual value of the Undivided Interest or the Real Property Interest, with any
other  Person.  The Owner  Trustee and the Owner  Participant  are not under the



                                      -89-

6091.BURNHAM.1106.27:1




control of nor shall they be deemed to be under the control of any other  Person
having any  interest in Unit 2, and shall not be the agent of or have a right or
power to bind any such Person (other than the Owner  Participant  as regards the
Owner Trustee) without its express written consent. The Owner Trustee (on behalf
of the Owner Participant) and the owner Participant (on its own behalf) have and
at all  times  shall  retain  the right  separately  to take or  dispose  of the
Undivided Interest and the Real Property Interest, subject only to the rights of
the Lessee and the Loan Participant under the Transaction  Documents.  The Owner
Trustee and the Owner  Participant  accordingly do not intend to create any form
of  partnership  or joint  venture  with  any  other  Person  by  virtue  of the
transactions  contemplated hereby or by any of the Transaction Documents. In the
event that it is determined, contrary to the intent of the Owner Trustee and the
Owner Participant, that, for purposes of the Code or any other income tax law, a
form of  partnership  or joint venture  exists  between the Owner Trustee or the
Owner  Participant  and any  other  Person,  the  Owner  Trustee  and the  Owner
Participant  hereby  elect to the  extent  permitted  by law (i) not to have the
partnership  provisions of the Code or such other income tax law apply to any of
the transactions  contemplated hereby or by any of the Transaction Documents and
(ii) to be treated solely as owning the Undivided Interest and the Real Property
Interest.

                (c)  Governing  Law.  This  Participation   Agreement  has  been
        negotiated  and delivered in the State of New York and shall be governed
        by, and be construed in  accordance  with,  the laws of the State of New
        York.

                (d) Amendments,  Supplements,  etc.  Neither this  Participation
        Agreement  nor any of the terms  hereof  may be  amended,  supplemented,
        waived or modified  orally,  but only by an instrument in writing signed
        by the party against which enforcement of such change is sought.

                (e)  Headings.  The headings of the sections and  paragraphs  of
        this paragraphs of this  Participation  Agreement have been inserted for
        convenience  of reference only and shall in no way restrict or otherwise
        modify any of the terms or provisions hereof.

                (f)   Bankruptcy  of  Owner   Participant.   If  (a)  the  Owner
        Participant  or the  Owner  Trustee  becomes  a  debtor  subject  to the
        reorganization  provisions  of the  Bankruptcy  Code,  or any  successor
        provision,


                                      -90-

6091.BURNHAM.1106.27:1





(b) pursuant to such  reorganization  provisions  the Owner  Participant  or the
Owner Trustee is required, by reason of the Owner Participant being held to have
recourse  liability  directly  or  indirectly  to the  Holder of any Note or the
Indenture Trustee, to make payment on account of any amount payable as principal
or interest on such Note and (c) such Holder or the Indenture  Trustee  actually
receives any Excess Amount which  reflects any payment by the Owner  Participant
on account  of clause (b) of this  Section1  then such  Holder or the  Indenture
Trustee, as the case may be, shall promptly refund to the Owner Participant such
Excess Amount. For purposes of this Section,  "Excess Amount means the amount by
which such payment exceeds the amount which would have been received on or prior
to the date of such payment by such Holder or the Indenture Trustee if the Owner
Participant  or the  Owner  Trustee  had  not  become  subject  to the  recourse
liability  referred to in clause (b) of this Section,  Nothing contained in this
Section shall prevent such Holder or the  Indenture  Trustee from  enforcing any
personal  recourse  obligation (and retaining the proceeds thereof) of the Owner
Participant expressly provided for under this Participation Agreement.

                  (g) Entire Agreement.  This Participation Agreement (including
the Schedules  hereto and the waiver letter dated as of the Closing  Date),  the
other  Transaction  Documents  and the Financing  Documents  supersede all prior
agreements, written or oral, between or among any of the parties hereto relating
to the  transactions  contemplated  hereby and  thereby  and each of the parties
hereto represents and warrants to the others that this  Participation  Agreement
and the other Transaction  Documents and the Financing Documents  constitute the
entire  agreement among the parties  relating to the  transactions  contemplated
hereby and thereby.

                (h)  Publicity.  Each party hereto agrees that it will not issue
or release for  external  publication  any article or  advertising  or publicity

delivered  pursuant to Sections  11(a) (12) and 11(a) (27) of the  Participation
Agreement.



6091.BURNHAM.1106.08:l




                As such counsel we have examined originals or copies,  certified
or  otherwise  identified  to  our  satisfaction,  of  such  corporate  records,
agreements   and   other   instruments.,    certificates,    orders,   opinions,
correspondence   with   public   officials,   certificates   of   officers   and
representatives  of  Funding  Corp.  and  other  documents,  as we  have  deemed
necessary  or advisable  for the  purposes of  rendering  the opinions set forth
herein.

                  Based on the foregoing, we are of the opinion that:

                  (1) Funding Corp. is a corporation  duly organized and validly
        existing in good  standing  under the laws of the State of Delaware  and
        has the  corporate  power  and  authority  to carry on its  business  as
        presently conducted, own its properties,  and enter into and perform its
        obligations under the Participation Agreement and each other Transaction
        Document and each Financing Document to which it is a party.

                  (2) The execution,  delivery and  performance by Funding Corp.
        of the Participation  Agreement and each other Transaction  Document and
        each  Financing  Document  to  which  it  is a  party,  have  been  duly
        authorized  by all  necessary  corporate  action on the part of  Funding
        Corp.  and do not require the consent or approval of the  stockholder of
        Funding Corp.  The  Participation  Agreement and each other  Transaction
        Document and each  Financing  Document to which Funding Corp. is a party
        have been duly executed and delivered by Funding Corp. and, assuming due
        authorization,  execution  and  delivery  by each other  party  thereto,
        constitute  legal,   valid  and  binding  agreements  of  Funding  Corp.
        enforceable against it in accordance with their respective terms.

                (3) Neither the  execution,  delivery or  performance by Funding
        Corp. of the Participation  Agreement or any other Transaction  Document
        or any Financing  Document to which it is a party,  nor the consummation
        by  Funding  Corp.  of  the  transactions   contemplated   thereby,  nor
        compliance by Funding Corp. with the provisions  thereof conflicts with,

        or  results  in the  breach of any  provision  of,  the  Certificate  of
        Incorporation  or By-Laws of Funding Corp.  or any Federal,  Delaware or
        New York law or any  indenture,  mortgage or agreement to which  Funding
        Corp. is a party or by which it or its property is bound or requires any
        Governmental  Action  with  respect  to  Funding  Corp.  under  Federal,
        Delaware or New York law, except such as have been, duly obtained, given
        or accomplished.

                  The opinions set forth above are subject to the qualifications
that  enforceability of the  Participation  Agreement and each other Transaction
Document  and each  Financing  Document  to which  Funding  Corp.  is a party in
accordance with their respective terms may be limited by bankruptcy, insolvency,
reorganization,  moratorium  or other  similar  laws  affecting  enforcement  of
creditors' rights generally, as well as the general principles of equity and the
availability of equitable remedies.

                  This  opinion  is limited  to the  Federal  laws of the United

Dear Sirs:

                We have acted as special New York  counsel  for Burnham  Leasing
Corporation, a New York corporation (the Owner Participant),  in connection with
the transactions contemplated by the Participation Agreement1 dated as of August
12, 1986, (the Participation Agreement),  among the Owner Participant, The First
National Bank of Boston,  a national  banking  association,  individually  and a
Owner Trustee,  First PV Funding Corporation,  a Delaware corporation,  Chemical
Bank, a New York banking  corporation,  as Indenture  Trustee and Public Service
Company 6f New Mexico,  a New Mexico  corporation.  All  capitalized  terms used
herein and not  otherwise  defined  herein  shall have the meanings set forth in
Appendix A to the  Participation  Agreement.  This  opinion  is being  delivered
pursuant to Section 11(a) (14) of the Participation Agreement.

                  As  such  counsel  we  have  examined   originals  or  copies,
certified  or  otherwise  identified  to our  satisfaction,  of  such  corporate
records,  agreements  and other  instruments,  certificates;  orders,  opinions,
correspondence   with   public   officials,   certificates   of   officers   and
representatives of the Owner Participant, and other documents, as we have deemed
necessary  or advisable  for the  purposes of  rendering  the opinions set forth
herein.

                  Based upon the foregoing, we are of opinion that:




6091.BURNHAM.1106.08:1





                (1) The Owner Participant is a corporation  validly existing and
        in good standing  under the laws of its state of  incorporation  and has
        the  corporate  power  and  authority  to  enter  into and  perform  its
        obligations under the Participation Agreement and each other Transaction
        Document to which it is a party.

                    (2) The making and  performance by the Owner  Participant of
         the  Participation  Agreement  and each other  Transaction  Document to
         which the Owner Participant is a party have been duly authorized by all
         necessary  corporate action on the part of the Owner Participant and do
         not require the consent or approval of its stockholders (except for any
         such consents or approvals as have been obtained).

                    (3) The  Participation  Agreement and each other Transaction
         Document  to which  the  Owner  Participant  is a party  have been duly
         executed and delivered by the Owner  Participant and constitute  legal,
         valid and  binding  agreements  of the Owner  Participant,  enforceable
         against it in accordance with their respective  terms,  subject,  as to
         enforceability, to applicable bankruptcy,  insolvency,  reorganization,
         moratorium  and other  similar laws  affecting  the  enforceability  of
         creditors'  rights  generally  and  to  general  principles  of  equity
         (regardless  of  whether  an  enforcement  action  is  considered  in a
         proceeding in equity or at law). In addition, we wish to point out that
         provisions in the Participation  Agreement and in the other Transaction
         Documents  to which the Owner  Participant  is a party which permit the
         Owner Participant to make determinations or take actions may be subject
         to a requirement that such  determinations  be made and such actions be
         taken on a reasonable basis and in good faith.

                    (4) Neither the  execution,  delivery or  performance by the
         Owner  Participant  of  the   Participation   Agreement  or  any  other
         Transaction  Document to which it is a party,  nor the  consummation by
         the Owner  Participant of the transactions  contemplated  thereby,  nor
         compliance  by the  Owner  Participant  with  the  provisions  thereof,
         conflicts  with,  or  results  in the  breach of any  provision  of the
         corporate   charter  or  the  by-laws  of  the  Owner   Participant  or
         contravenes any agreement or instrument to which the Owner  Participant
         


                                       -2-

6091.BURNHAM.1106.08:1




        is a party of which we are aware,  or requires any  Governmental  Action
        with  respect to the Owner  Participant  under  Federal or New York law,
        except such as are contemplated by the Transaction  Documents (including
        the filing of Form U-7D with the SEC within 30 days of the date  hereof)
        or the Financing Documents or such as have been duly obtained,  given or
        accomplished.

                We are  members  of the  Bar of the  State  of New  York  and we
express  no opinion  with  regard to any law other than the laws of the State of
New York and the Federal  laws of the United  States of America.  We do not hold
ourselves out as experts on the laws of the State of Arizona or the State of New
Mexico,  and to the  extent  such laws may be  relevant  to any  opinion  herein
expressed,  we have, with your  permission,  relied upon the opinions dated this
date of Meyer,  Hendricks,  Victor,  Osborn &  Maledon;  Snell & Wilmer;  Rodey,
Dickason,  Sloan,  Akin & Robb,  P.A.;  and  Keleher  &  McLeod,  P.A.,  without

Act.

Gentlemen:

                We have acted as special  counsel to The First  National Bank of
Boston, a national banking association (FNB) in connection with the transactions
contemplated by the  Participation  Agreement,  dated as of August 12, 1986 (the
Participation  Agreement),   among  Burnham  Leasing  Corporation,  a  New  York
corporation (the Owner Participant),  First PV Funding  Corporation,  a Delaware
corporation,  FNB, in its individual capacity and as Owner Trustee under a Trust
Agreement  dated as of August  12,  1986,  with the Owner  Participant  (in such
fiduciary  capacity,  the Owner  Trustee),  Chemical  Bank,  a New York  banking
corporation,  as Indenture  Trustee and Public Service Company of New Mexico,  a
New Mexico  corporation.  All  capitalized  terms used herein and not  otherwise
defined  herein  shall  have  the  meanings  set  forth  in  Appendix  A to  the
Participation  Agreement.  This opinion is being  delivered  pursuant to Section
11(a) (16) of the Participation Agreement.

                As such counsel we have examined originals or copies,  certified
or  otherwise  identified  to  our  satisfaction,  of  such  corporate  records,
agreements and other instruments, certificates, orders, opinions, correspondence
with public officials,  certificates of officers and representatives of FNB, and
other  documents,  as we have deemed  necessary or advisable for the purposes of
rendering the opinions set forth  herein.  With respect to our opinion set forth
in paragraph 6 hereof,  we have assumed that,  for federal  income tax purposes,



6091.BURNHAM.1106.08:l




the trust  created by the Trust  Agreement  will be  treated as a grantor  trust
subject to section 671 of the Internal Revenue Code of 1954, as amended. We have
also assumed that each of the Transaction Documents is legal, valid, binding and
enforceable  under  the laws of the  State  of New  York,  subject  only to such
limitations as are set forth below.

                  Based on the foregoing, we are of the opinion that:

                (1) FNB is a national  banking  association  duly  organized and
        validly existing in good standing under the laws of the United States of
        America and has all  requisite  corporate  power and  authority to enter
        into and perform its  obligations  under (x) the Trust Agreement and, to
        extent it is a party to the  Participation  Agreement in its  individual
        capacity,  the Participation  Agreement and (y) acting as Owner Trustee,
        the Participation Agreement and each other Transaction Document to which
        FNB is a party as Owner Trustee.

                (2) The  Participation  Agreement  and  each  other  Transaction
        Document  to which  FNB is a party  have  been  duly  authorized  by all
        necessary  corporate  action of FNB (in its  individual  capacity  or as
        Owner  Trustee,  as the case may be) and,  upon  execution  and delivery
        thereof,  the  Participation  Agreement and each such other  Transaction
        Document will be duly  executed and  delivered and will be legal,  valid
        and  binding   agreements  of  FNB  (in  its   respective   capacities),
        enforceable against it (in its respective capacities) in accordance with
        their respective  terms except as enforcement  thereof may be limited by
        applicable bankruptcy, insolvency, reorganization, moratorium or similar
        laws affecting the rights of creditors  generally and general principles
        of equity (regardless of whether such  enforceability is considered in a
        proceeding  in equity or at law) and except that the  enforceability  of
        certain of the remedial  provisions  in the  Indenture may be limited by
        applicable state laws, which laws,  however,  do not in our opinion make
        the remedies  provided in such  documents  inadequate  for the practical
        realization of the benefits provided thereby.




                                       -2-

6091.BURNHAM.1106.08:1





                (3)  Neither  the  execution  and  delivery  by (X) of the Trust
        Agreement  and, to the extent FNB is a party  thereto in its  individual
        capacity,  the Participation  Agreement and (y) the Owner Trustee of the
        Participation  Agreement and each other Transaction Document (other than
        the Trust  Agreement)  to which the Owner  Trustee  is a party,  nor the
        performance by FNB, in its individual  capacity or as Owner Trustee,  as
        the case may be, of its  obligations  under  each,  conflicts  with,  or
        results in the breach of any  provision  of, its  Charter or By-Laws and
        does not  contravene  any Applicable Law of the United States of America
        or The  Commonwealth  of  Massachusetts  governing  the banking or trust
        powers of FNB, and does not contravene any provision of, or constitute a
        default under, any indenture,  mortgage,  contract or other  instrument,
        known to us, to which FNB is a party or by which it is bound or  require
        any  Governmental  Action with  respect to the Owner  Trustee  under any
        Federal or  Massachusetts  law except  such as are  contemplated  by the
        Transaction  Documents or the  Financing  Documents or such as have been
        duly obtained, given or accomplished.

                (4)  To the  best  of  our  knowledge,  after  due  inquiry,  no
        Indenture  Default or  Indenture  Event of Default has  occurred  and is
        continuing and the Owner Trustee is not in violation of any of the terms
        of the Participation  Agreement or of any other Transaction  Document to
        which it is a party.

                  (5) To the  best of our  knowledge,  but  without  independent
        investigation,  there is no action,  suit,  investigation  or proceeding
        pending,  or to our  knowledge,  threatened  against FNB (in either such
        capacity) before any court, arbitrator or administrative or governmental
        body  and  which   relates  to  its  banking  or  trust  powers   which,
        individually or in the aggregate,  if decided adversely to the interests
        of FNB (in either such capacity),  would have an adverse effect upon the
        ability of FNB (in either  such  capacity)  to perform  its  obligations
        under the Participation  Agreement or any other Transaction  Document to
        which it is a party (in any capacity).

                  (6)  Neither the  execution  by FNB (in any  capacity)  of the
        Participation   Agreement,   the  Initial   Series  Note  or  any  other
        Transaction  Document to which it (in any capacity) is a party,  nor the
        performance in any capacity by it of its  obligations  thereunder,  will
        subject the Trust Estate or the Lease Indenture  Estate,  or any portion
        thereof, to any Owner Trustee's Lien.


                                       -3-

6091.BURNMAM.1106.08:1





                (7) Other than any tax imposed on FNB in its individual capacity
        or the Owner Trustee in respect of any  compensation to which FNB or the
        Owner  Trustee,  as the case may be, is  entitled  or  receives  for its
        services in  connection  with the  performance  of its duties  under the
        Trust Agreement or the Indenture,  no taxes,  fees or other charges will
        be  imposed  by The  Commonwealth  of  Massachusetts  or  any  political
        subdivision  thereof on or with  respect to the  execution,  delivery or
        performance of any of the  Transaction  Documents or with respect to the
        issuance of the Initial  Series Note,  except such taxes,  fees or other
        charges which would have been imposed had FNB or the Owner  Trustee,  as
        the case may be, not performed in The Commonwealth of Massachusetts  its
        duties under the Trust Agreement and the other Transaction Documents.

                The  opinions  expressed  herein  are  limited  to  1aws  of The
Commonwealth  of  Massachusetts  and the  Federal  laws of the United  States of
America relating to the banking and trust powers of FNB.


                                Very truly yours,

      [Letterhead of Shaw, Pittman, Potts & Trowbridge]
                                                     August 18, 1986

To Each Person Listed on The Attached Schedule

                 SALE AND LEASEBACK OF AN UNDIVIDED INTEREST IN
                  PALO VERDE NUCLEAR GENERATING STATION UNIT 2
                          AND CERTAIN COMMON FACILITIES

Gentlemen:

                We have  acted  as  special  NRC  counsel  for  Burnham  Leasing
Corporation, a New York corporation (the Owner Participant),  in connection with
the transactions contemplated by the Participation Agreement, dated as of August
12, 1986, (the Participation Agreement),  among the Owner Participant, The First
National Bank of Boston,  a national  banking  association,  individually and as
Owner  Trustee (the Owner  Trustee),  First PV Funding  Corporation,  a Delaware
corporation, Chemical Bank, a New York banking corporation, as Indenture Trustee
and  Public  Service  Company  of New  Mexico,  a New  Mexico  corporation.  All
capitalized  terms used herein and not otherwise  defined  herein shall have the
meanings set forth in Appendix A to the Participation Agreement. This opinion is
being delivered pursuant to Section 11(a)(18) of the Participation Agreement.

                The Owner  Participant  and Owner  Trustee  have  requested  our
opinion with respect to three related  issues:  (1) whether the NRC Order issued
December  12,  l986,  by  the  Nuclear  Regulatory  Commission  ("NRC"),   which
authorizes PNM to proceed with the proposed  transaction  without  requiring the
Owner  Participant  or Owner Trustee to become NRC licensees  during the term of
the Facility Lease of the Undivided Interest,  is a final order; (2) whether the
Owner  Participant  or Owner  Trustee  would  have any  licensing  or  reporting
obligations  during  the  Lease  Term  under  any  nuclear-related   statute  or



6091.BURNHAM.1106.08:1




regulation;  and (3) whether the  Price-Anderson  Act, 42 U.S.C.  5 2210,  would
protect the Owner  Participant and Owner Trustee against  liability with respect
to any  "nuclear  incident"  (as  defined by the Act) and  whether the Act would
impose any  financial  obligations  on the Owner  Participant  and Owner Trustee
during the lease term.

                  In reaching the  opinions on these issues set forth below,  we
have  reviewed  and  relied  upon the NRC  Order and the  SECY-85-367  NRC staff
document to which the NRC Order refers.  We also have reviewed PNM's Application
to the NRC for approval of the  transaction and various  materials  submitted in
support of that Application,  including the Arizona Nuclear Power Plant ("ANPP")
Project Participation  Agreement and Amendment No. 10 thereto.  Finally, we have
reviewed  successive  drafts  (dated  _____,  _____  and  _____ of the  relevant
transaction documents, in particular the Participation Agreement among the Owner
Participant,  Owner Trustee PNM and others,  Appendix A thereto  (Definition  of
Terms)'  and the  Facility  Lease  between  the Owner  Trustee  and PNM. We have
assumed for purposes of our opinions that the final versions of these  documents
will not differ materially from the _________ draft versions.


                The Finality of the NRC Order

                The NRC Order  constitutes  final agency action,  pursuant to 42
U.S.C. 2239(a), on PNM's application for a license amendment.  The Hobbs Act, 28
U.S.C.  ss. 2344,  permits any party aggrieved" by the NRC Order to petition for
review in the appropriate  court of appeals within sixty (60) days of its entry.
Since no person  intervened in the NRC  proceeding to oppose PNM' 5 application,
however,  an  appeal  from  the  Order by any  person  other  than PNM  would be
dismissed on standing  grounds.  E.g.,  American Civil Liberties Union v F.C.C.,
774 F.2d 24, 25 (1st Cir. 1985) ("The courts have  consistently  interpreted the
term "party  aggrieved" to require that a petitioner  have  participated  in the
agency proceedings"); Gage v. AEC, 479 F.2d 1214, 1218 (D.C. Cir. 1973).

                Section 2.206 of the NRC Rules of Practice (l0 C.F.R. ss. 2.206)
provides that "[a]ny person may file a request for [the  appropriate NRC office]
to institute a proceeding  pursuant to ss. 2.202 to modify,  suspend or revoke a



                                       -2-

6091.BURNHAM.1106.08:1




license,  or for such other action as may be appropriate."  This provision would
permit any person to request  the NRC during the term of the  Facility  Lease to
reconsider  its Order and amend the  License so as to add the Owner  Participant
and Owner  Trustee as  licensees.  The  likelihood  that such a request would be
filed, or that if filed it would be granted,  appears to be extremely remote. In
any event, this would not affect the "finality" of the NRC Order.

                Similarly,  Section  2.204 of the Rules of  Practice  (10 C.F.R.
2.204)  authorizes  the NRC to take action of its own accord to modify a license
"by issuing an amendment on notice to the licensee  that the licensee may demand
a hearing with respect to all or any part of the  amendment."  It seems  equally
unlikely  that the NRC would take such  action  during the Lease Term to add the
Owner Participant or Owner Trustee as a licensee of the Palo Verde facility.


                License and Reporting Obligations of the Owner Participant and
Owner Trustee

                The NRC Order includes the condition  requested by PNM that "the
lessor and anyone else who may acquire an interest under the  transaction  which
is the subject of this  application are prohibited  from exercising  directly or
indirectly  any control over the licensees of the Palo Verde nuclear  facility,"
and therefore concludes that the proposed sale-leaseback transaction "shall have
no  effect  on the  Palo  Verde  nuclear  facility  throughout  the  term of the
license."  The  SECY-85-367  staff  recommendation  adopted by the Order further
states:


                [W]here as here,  the sale of the facility is simply a step in a
        transaction  involving only the  refinancing  of capital,  and where the
        investor  owner  only  serves in a passive  role  with no  authority  or
        control  over  the  nuclear  facility,  the  Staff  can  perceive  of no
        regulatory purpose which would be served by an interpretation of Section
        101  of the  Atomic  Energy  Act  the  source  of  the  NRC's  licensing
        authority], which requires the licensing of such financial investors.




                                       -3-

6091.BURNHAM.1106.08:1





                The effect of this  analysis and the NRC Order is that the Owner
Participant  and Owner Trustee are not required to become  licensees  during the
Lease Term and  therefore  will incur no  obligations  as licensees  during that
period.  By the same token, we believe that the Arizona Public Service  Company,
as Project Manager and Operating Agent under the ANPP  Participation  Agreement,
and PNM, as lessee of the undivided interest from the Owner Trustee, will remain
during the Lease Term the relevant  licensees under Facility  Operating  License
No. NPF-51 subject to all license obligations with respect to the management and
operation  of  the  PVNGS.  Such  license  obligations  include  the  costs  and
responsibilities of decommissioning the facility.

                  In addition,  it is our opinion that the Owner Participant and
Owner Trustee will have no reporting obligations during the Lease Term under any
nuclear-related   law  or  regulation.   With  one  exception,   such  reporting
obligations  are limited to  licensees  or holders of  construction  permits for
nuclear  facilities.  The exception is Section 206 of the Energy  Reorganization
Act of 1974, 42 U.S.C.  5846, which provides that each director and "responsible
officer"  of  any  firm  "constructing,  owning,  operating,  or  supplying  the
components of any facility or activity which is licensed or otherwise regulated"
by the NRC, "who obtains information reasonably indicating that such facility or
activity or basic  components  supplied to such  facility"  fails to comply with
nuclear laws or regulations relating to substantial safety hazards or contains a
defect that could create a substantial  safety hazard,  shall immediately notify
the NRC of the failure to comply or the defect."  Although the literal  language
of Section 206 would encompass even unlicensed owners of nuclear facilities, the
NRC regulations  implementing this provision (10 C.F.R. Part 21) make clear that
its reporting  requirements.  extend only to licensees  and to firms  (including
directors and responsible  officers thereof) that construct or supply components
to  licensed  facilities.  10  C.F.R.  21.2.  Just as the NRC Order in this case
reflects the agency's understanding that despite the literal language of Section
101 of the Atomic  Energy  Act the sale of an  ownership  interest  in a nuclear
facility does not require  licensing of the passive  investor owner,  Part 21 of
the NRC  Regulations  reflects the  agency's  understanding  that the  reporting
requirements  established  by Section  206 were not  intended  to reach  passive


                                       -4-

investors  or-lenders  and make sense only if applied to those persons  actually
involved in the management operation or construction of a nuclear facility or in
the supply of components  for such  facilities.  Accordingly,  it is our opinion
that  neither  Section 206 nor its  implementing  regulations  would  impose any
reporting  requirements  on the Owner  Participant  or Owner Trustee  during the
Lease Term.


                The Price-Anderson Act

                Section 170 of the  Price-Anderson  Act,  in its  present  form,
requires  "licensees" of nuclear facilities to maintain financial  protection in
specified  amounts  against  liability for "nuclear  incidents" (as that term is
defined in the Price-Anderson Act, 42 U.S.C. 2014(q)), which protection includes
both  mandatory  insurance  coverage  and  retroactive  premium  assessments  of
$5,000,000 per facility for each nuclear incident.  42 U.S.C. 2210(a) & (b). The
Price-Anderson Act also protects all "persons indemnified" against liability for
nuclear incidents beyond the sum of the amount covered by the required financial
protection  and the limits of  indemnification  provided  by the NRC.  42 U.S.C.
2210(e).. The Act defines the term "persons indemnified" to include both persons
who are required to maintain financial  protection,  i.e.,  licensees,  and "any
other person who may be liable for public  liability."  42 U.S.C.  2014(t).  The
term public liability," in turn, is defined to mean "any legal liability arising
out of or  resulting  from a nuclear  incident"  (emphasis  added),  except  for
workers'  compensation claims of persons employed at the site where the incident
occurs,  claims arising out of an act of war, and claims  relating to loss of or
damage  to  property  located  at the  site of and used in  connection  with the
activity where the incident occurs. 42 U.S.C. 2014(w).

                In light of the NRC Order  holding that PNM remains the licensee
of the Palo Verde  facility  during the lease  term,  in our  opinion  the Owner
Participant  and Owner Trustee will have no obligation  under the Price Anderson
Act or its implementing  regulations to maintain financial protection during the
lease  term.  In  addition,  the terms of the Act  described  above  extend full
financial  protection  to  the  Owner  Participant  and  Owner  Trustee  against
liability for nuclear incidents.



                                       -5-

6091.BURNHAM.1106.08:1





                In summary,  it is our opinion  that:  (1) the NRC Order  issued
December 12, 1985, is final subject only to  reconsideration  at the instance of
the NRC or some other person under  Sections  2.204 and 2.206 of the NRC'S Rules
of Practice;  (2) under the terms of the NRC Order and under a proper reading of
Section 101 of the Atomic Energy Act and its  implementing  regulations in their
present form, the Owner  Participant and Owner Trustee will not have any license
or reporting  obligations during the lease term under any nuclear-related law or
regulation;  and (3) the  Price-Anderson  Act in its present  form  protects the
Owner  Participant  and  Owner  Trustee  against  financial  exposure  from  any
liability for nuclear  incidents and does not require the Owner  Participant  or
Owner  Trustee to maintain  financial  protection  during the lease term against
liability for such nuclear incidents.


                                            Sincerely,

                          AND CERTAIN COMMON FACILITIES

Dear Sirs:

                We have acted as special  counsel for Public Service  Company of
New Mexico, a New Mexico  corporation (PNM), in connection with the transactions
contemplated by the  Participation  Agreement,  dated as of August 12, 1986 (the
Participation  Agreement),   among  Burnham  Leasing  Corporation,  a  New  York
corporation,  as Owner  Participant,  First PV Funding  Corporation,  a Delaware
corporation,  The First National Bank of Boston, a nationa1 banking association,
individually   and  as  Owner  Trustee,   Chemical  Bank,  a  New  York  banking
corporation,  individually  and as Indenture  Trustee,  and PNM. All capitalized
terms used herein and not otherwise  defined  herein shall have the meanings set
forth in  Appendix  A to the  Participation  Agreement.  This  opinion  is being
delivered pursuant to Section 11(a) (20) of the Participation Agreement.

                  As  such  counsel  we  have  examined   originals  or  copies,
certified  or  otherwise  identified  to our  satisfaction,  of  such  corporate
records,   agreements   and   other   instruments,    certificates,    opinions,
correspondence  with public  officials,  certificates  of  officers,  management
personnel  and  representatives  of PNM,  and such other  documents,  as we have
deemed  necessary  or advisable  for the purposes of rendering  the opinions set
forth herein.


6091.BURNHAM.1106.08:l





                Based on the  foregoing  and subject to the  qualifications  set
forth below, we are of the opinion that:

                (1) The  Participation  Agreement  and  each  other  Transaction
        Document to which PNM is a party have been duly  executed and  delivered
        by PNM,  and,  assuming the due  authorization,  execution  and delivery
        thereof by the other parties thereto,  the  Participation  Agreement and
        each other  Transaction  Document to which PNM is a party constitute the
        legal, valid and binding agreements of PNM,  enforceable  against PNM in
        accordance with their respective terms.

                (2) Neither the execution, delivery or performance by PNM of the
        Participation  Agreement  or  any  other  Transaction  Document  or  any
        Financing  Document to which PNM is a party, nor the consummation by PNM
        of the transactions contemplated thereby, nor compliance by PNM with the
        provisions   thereof,   conflicts  with,  or  results  in  a  breach  or
        contravention  of any of the  provisions  of, the  Restated  Articles of
        Incorporation  or By-Laws of PNM, or any Federal or New York  Applicable
        Law.

                  (3) No  Federal  or New York  Governmental  Action  under  any
        Applicable  Law  now in  effect  is  required  in  connection  with  the
        execution, delivery or performance by PNM of, or the consummation by PNM
        of the transactions  contemplated by, the Participation Agreement or any
        other Transaction  Document in effect on the date hereof to which PNM is
        a party,  except such Federal and New York  Governmental  Actions (i) as
        have been duly obtained,  given or accomplished,  (ii) as are routine in
        nature and that cannot be  obtained,  or are not  normally  applied for,
        prior to the time they are required,  (iii) as may be required under the
        Holding  Company Act,  (iv) as may be required to be obtained,  given or
        accomplished from time to time in connection with the maintenance,  use,
        possession, operation or improvement of Unit 2 or otherwise with respect
        to Unit 2 and PNM's or the operating Agent's involvement therewith,  (V)
        as may be required in  consequence  of any  transfer of ownership of any
        Note or Bond by the Holder thereof, the beneficial interest in the Trust
        by the Owner Participant, or the Undivided Interest or the Real Property



                                       -2-

6091.BURNHAM.1106.08:l




        Interest by ,the Owner  Trustee,  (vi) as may be required in consequence
        of the  issuance,  sale or exchange and  delivery of or any  obligations
        issued under and pursuant to any Collateral  Trust Indenture (other than
        the  Initial  Series  Note),  (vii)  as  may  be  required  by  existing
        Applicable  Law if,  after  termination  or  expiration  of the Facility
        Lease, PNM should provide transmission services for the Owner Trustee or
        (viii)  as may be  required  under  Federal  or New  York law not now in
        effect.  No  Federal  or New  York  Governmental  Action  is or  will be
        required (a) in connection with the  participation by the Owner Trustee,
        the Indenture Trustee,  the Owner Participant or the Loan Participant in
        the consummation of the transactions  contemplated by the  Participation
        Agreement,  any other Transaction  Document in effect on the date hereof
        or any  Financing  Document  in effect  on the date  hereof or (b) to be
        obtained by any of such Persons  during the term of the  Facility  Lease
        with  respect to Unit 2 except  such  Federal  or New York  Governmental
        Actions (i) as have been duly obtained,  given or accomplished,  (ii) as
        may be required  by  Applicable  Law not now in effect,  (iii) as may be
        required in consequence of any transfer of ownership of any Note or Bond
        by the Holder thereof, the beneficial interest in the Trust by the Owner
        Participant,  or the Undivided Interest or the Real Property Interest by
        the  Owner  Trustee,  (iv)  as may be  required  in  consequence  of the
        issuance,  sale or exchange  and delivery of or any  obligations  issued
        under and pursuant to any  Collateral  Trust  Indenture  (other than the
        Initial  Series Note),  (v) as would be required by existing  Applicable
        Law upon  termination  or expiration of the Facility Lease in connection
        with taking possession of an interest in Unit 2, (vi) as may be required
        by existing  Applicable  Law if, after  termination or expiration of the
        Facility Lease, PNM should provide  transmission  services for the Owner
        Trustee or cease to be agent for the Owner Trustee as provided under the
        Assignment and Assumption, or (vii) as may be required in consequence of
        any  exercise  of  remedies  or  other  rights  by any  such  Person  in
        connection with taking possession of an interest in Unit 2.

                (4) So long as the  Facility  Lease is in effect,  assuming  the
        proper  filing of Form U-7D with the SEC on or within 30 days  after the



                                       -3-

        date  hereof,  under  Federal  law  now  in  effect,  neither  the  Loan
        Participant, the Owner Participant, FNB nor the Owner Trustee will be or
        become,  solely by reason of either its entering into the  Participation
        Agreement  or any other  Transaction  Document to which any of them is a
        party, or the transactions  contemplated thereby,  subject to regulation
        (including,  without  limitation,  as an electric  utility  company,  an
        electric  utility,  a  public-utility  company or corporation,  a public
        utility,  a  holding  company,  a public  utility  holding  company,  an
        electric  corporation,  or a  utility  company  or  corporation)  by any
        Federal or New York public utility  commission or other regulatory body,
        authority  or  group  (including,  without  limitation,  the SEC and the
        FERC).  PNM is not a "holding  company" or a  "subsidiary  company" of a
        "holding  company" or an "affiliate" of a "holding  company"  within the
        meaning of the Holding Company Act.

                (5)  PNM  is  not  an   "investment   company",   or  a  company
        "controlled"  by an  "investment  company",  within  the  meaning of the
        Investment Company Act.

                The opinions  set forth above are subject to the  qualifications
that (i) enforceability of the Participation Agreement and the other Transaction
Documents to which PNM is a party in accordance with their  respective terms may
be  limited  by  bankruptcy,  insolvency,  reorganization,  moratorium  or other
similar laws affecting  enforcement of creditors' or lessors' rights  generally,
as well as the general  principles of equity and the  availability  of equitable
remedies,   and  (ii)  certain  laws  and  judicial  decisions  may  affect  the
enforceability  against  PNM of certain  rights  and  remedies  provided  in the
Transaction Documents. With respect to the latter qualification, however, we are
of the  opinion  that none of such laws now in effect and none of such  judicial
decisions make the rights and remedies  provided in the  Transaction  Documents,
taken  as a  whole,  inadequate  for  the  realization  of the  benefits  of the
Transaction Documents.

To Each Person Listed on The Attached Schedule


                 SALE AND LEASEBACK OF AN UNDIVIDED INTEREST IN
                  PALO VERDE NUCLEAR GENERATING STATION UNIT 2
                          AND CERTAIN COMMON FACILITIES

Dear Sirs:

                  We have acted as general counsel for Public Service Company of
New Mexico, a New Mexico  corporation (PNM), in connection with the transactions
contemplated by the  Participation  Agreement,  dated as of August 12, 1986 (the
Participation  Agreement),   among  Burnham  Leasing  Corporation,  a  New  York
corporation, as Owner Participant, The First National Bank of Boston, a national
banking  association,  individually  and as  Owner  Trustee,  First  PV  Funding
Corporation,  a  Delaware  corporation,   Chemical  Bank,  a  New  York  banking
corporation,  as Indenture  Trustee,  and PNM. All capitalized terms used herein
and not otherwise defined herein shall have the meanings set forth in Appendix A
to the  Participation  Agreement.  This opinion is being  delivered  pursuant to
Section 11(a) (21) of the Participation Agreement.

                As such counsel we have examined originals or copies,  certified
or  otherwise  identified  to  our  satisfaction,  of  such  corporate  records,
agreements and other instruments, certificates, orders, opinions, correspondence
with public officials,  certificates of officers and representatives of PNM, and
other  documents,  as we have deemed  necessary or advisable for the purposes of
rendering the opinions set forth herein.




6091.BURNHAM.1106.08:1





                Based on the foregoing, we are of the opinion that:

                (1) PNM is a corporation  duly organized and validly existing in
        good  standing  under  the laws of the State of New  Mexico  and has the
        corporate  power and  authority  to carry on its  business as  presently
        conducted,  to own or hold under lease its  properties and to enter into
        and perform its  obligations  under the  Participation  Agreement,  each
        other  Transaction  Document to which PNM is a party, and each Financing
        Document  to which  PNM is a party.  PNM is duly  qualified  and in good
        standing to do business as a foreign corporation in the State of Arizona
        and has not failed to qualify to do business  or to be in good  standing
        in any other  jurisdiction  where  failure  so to  qualify or be in good
        standing would materially and adversely  affect the financial  condition
        of PNM or its  ability  to  perform  any of its  obligations  under  the
        Participation  Agreement, any other Transaction Document to which PNM is
        a party, or any Financing Document to which PNM is a party.

                (2)  The  execution,  delivery  and  performance  by  PNM of the
        Participation Agreement, each other Transaction Document to which PNM is
        a party,  and each Financing  Document to which PNM is a party have been
        duly authorized by all necessary corporate action on the part of PNM and
        do not require the consent or approval of the stockholders of PNM or any
        trustee or holder of any  indebtedness or other obligation of PNM, other
        than  (i)  the   Mortgage   Release,   (ii)  the  finding  of  the  ANPP
        Administrative  Committee  described  in  Section  15.6.2  of  the  ANPP
        Participation  Agreement, and (iii) such other consents and approvals as
        have been duly obtained, given or accomplished.

                (3) The Participation Agreement, each other Transaction Document
        to which PNM is a party,  and each Financing  Document to which PNM is a
        party have been duly executed and  delivered by PNM,  and,  assuming the
        due  authorization,  execution and delivery thereof by the other parties
        thereto,  the  Participation  Agreement,  each  such  other  Transaction
        Document and each such Financing  Document  constitutes the legal, valid
        and binding agreement of PNM, enforceable against PNM in accordance with
        their respective terms.


                                       -2-

6091.BURNHAM.1106.08:1





                (4) Neither the execution, delivery or performance by PNM of the
        Participation  Agreement, any other Transaction Document to which PNM is
        a party,  or any  Financing  Document  to which PNM is a party,  nor the
        consummation  by PNM  of  the  transactions  contemplated  thereby,  nor
        compliance  by PNM with  the  provisions  thereof,  conflicts  with,  or
        results in a breach or  contravention  of any of the  provisions of, the
        Restated Articles of Incorporation or By-Laws of PNM or any Affiliate of
        PNM, or any  Applicable  Law, or any indenture,  mortgage,  lease or any
        other  agreement  or  instrument,  known  to  us,  to  which  PNM or any
        Affiliate  of PNM is a party  or by  which  the  property  of PNM or any
        Affiliate of PNM is bound,  or results in the creation or  imposition of
        any Lien (other than  Permitted  Liens) upon any  property of PNM or any
        Affiliate of PNM.

                (5) No New Mexico  Governmental  Action under Applicable Law now
        in effect is  required in  connection  with the  execution,  delivery or
        performance by PNM of, or the  consummation  by PNM of the  transactions
        contemplated  by, the  Participation  Agreement,  any other  Transaction
        Document to which PNM is a party, or any Financing Document to which PNM
        is a party, except such New Mexico Governmental Actions (i) as have been
        duly obtained, given or accomplished,  and (ii) as may be required under
        existing New Mexico Applicable Law to be obtained, given or accomplished
        from  time  to time  after  the  date  hereof  in  connection  with  the
        maintenance,  use,  possession or operation of Unit 2 or otherwise  with
        respect to Unit 2 and PNM's  involvement  therewith  and which are,  for
        PVNGS, routine in nature and which we have no reason to believe will not
        be timely obtained. No New Mexico Governmental Action is required (a) in
        connection with the  participation  by the Owner Trustee,  the Indenture
        Trustee,   the  Owner   Participant  or  the  Loan  Participant  in  the
        consummation  of the  transactions  contemplated  by  the  Participation
        Agreement,  any other Transaction  Document in effect on the date hereof
        or any  Financing  Document  in effect  on the date  hereof or (b) to be
        obtained by any of such Persons  during the term of the  Facility  Lease
        with respect to Unit 2 except such New Mexico  Governmental  Actions (i)
        as have  been  duly  obtained,  given  or  accomplished,  (ii) as may be
        required by Applicable  Law not now in effect,  (iii) as may be required
        

                                       -3-
6091.BURNHAM.1106.08:1




        in consequence of any transfer of ownership of the Undivided Interest or
        the  Real  Property  Interest  by the  Owner  Trustee,  (iv) as would be
        required by existing  Applicable  Law upon  termination or expiration of
        the Facility Lease in connection  with taking  possession of an interest
        in Unit 2, (v) as may be required by existing  Applicable  Law if, after
        termination  or expiration  of the Facility  Lease,  PNM should  provide
        transmission services for the Owner Trustee or cease to be agent for the
        Owner Trustee as provided under the Assignment and  Assumption,  or (vi)
        as may. be required in  consequence of any exercise of remedies or other
        rights by any such Person in  connection  with taking  possession  of an
        interest in Unit 2.

                (6) Except as disclosed  in the  financial  statements  to which
        reference is made in Section  l0(a)(ll) of the  Participation  Agreement
        and in the reports to which  reference is made in Section 10 (a) (12) of
        the Participation Agreement,  there is no action, suit, investigation or
        proceeding  pending or, to our knowledge,  threatened against PNM before
        any  Federal  or New  Mexico  court,  arbitrator  or  administrative  or
        governmental  body which questions the validity or enforceability of the
        Participation  Agreement  or  any  other  Transaction  Document  or  any
        Financing  Document in effect on the date hereof or which,  individually
        or in the aggregate, if decided adversely to the interests of PNM, would
        have a material adverse effect on the business or financial condition of
        PNM or materially and adversely affect the ability of PNM to perform its
        obligations under the  Participation  Agreement or any other Transaction
        Document or any Financing Document in effect on the date hereof to which
        PNM is a party.

                (7)  The  lien of the  Existing  Mortgage  does  not  extend  to
        contract rights of PNM under the Transaction  Documents  (other than the
        Facility  Lease) or to the Generation  Entitlement  Share related to the
        Undivided Interest.

                The opinions  set forth above are subject to the  qualifications
that (i)  enforceability of the Participation  Agreement,  the other Transaction
Documents to which PNM is a party, and the Financing Documents to which PNM is a
party in accordance  with their  respective  terms may be limited by bankruptcy,



                                       -4-

6091.BURNHAM.1106.08:l



insolvency,   reorganization,   moratorium  of  other  similar  laws   affecting
enforcement of creditors' or lessors' rights  generally,  as well as the general
principles  of equity  and the  availability  of  equitable  remedies,  and (ii)
certain laws and judicial  decisions  may affect the  enforceability  of certain
rights and remedies provided in the Transaction  Documents.  With respect to the
latter qualification,  however, we are of the opinion that none of such laws now
in effect and none of such  judicial  decisions  make the  rights  and  remedies
provided  in  the  Transaction  Documents,  taken  as a  whole,  inadequate  for
enforcing  payment of the Initial Series Note and the security interest provided
by  the  Indenture  or  the  realization  of the  benefits  of  the  Transaction
Documents.

                In rendering the opinions set forth above,  we have relied as to
all matters  relating  to (A) the law of the State of New York,  solely upon the
opinion of Mudge Rose  Guthrie  Alexander  & Ferdon,  Special  Counsel  for PNM,
delivered pursuant to Section 11(a) (20) of the Participation  Agreement,  as to
which law we have, with your consent, made no independent investigation, (B) the
laws of the State of Arizona,  the Atomic  Energy Act and the Nuclear Waste Act,
solely  upon the  opinion  of Snell & Wilmer,  PNM's  Special  Arizona  Counsel,
delivered pursuant to Section 11(a) (22) of the Participation  Agreement,  as to
which we have, with your consent, made no independent investigation, and (C) the
Federal Power Act, upon the opinion of Newman & Holtzinger,  P.C., PNM's Special
FERC  Counsel,  delivered  pursuant to Section  11(a) (23) of the  Participation
Agreement,  as to  which  we  have,  with  your  consent,  made  no  independent
investigation. Each such opinion is satisfactory to us in form and scope, and we
believe you and we are justified in relying thereon.

                For  purposes  of this  opinion we have  assumed  that the Owner
Participant and the Lessor will exercise their rights, and that PNM will perform
its  obligations,  under  Section  13(c) of the  Facility  Lease  if it  becomes
necessary to do so to remain in compliance  with the New Mexico  Order.  We have
further  assumed  that no Lease  Transaction  (as  that  term is used in the New
Mexico Order) entered into by PNM subsequent to the date hereof will result in a
violation of the New Mexico Order.

                In rendering  the opinions set forth in  paragraphs  (4) and (5)
above,  we have not passed upon and do not purport to pass upon the  application
of so-called "blue sky" or securities laws of any jurisdiction.


                                        Very truly yours,

                                        KELEHER & MCLEOD, P.A.

                  PALO VERDE NUCLEAR GENERATING STATION UNIT 2
                          AND CERTAIN COMMON FACILITIES

Dear Sirs:

                We have  acted as Special  Arizona  counsel  for Public  Service
Company of New Mexico,  a New Mexico  corporation  (PNM), in connection with the
transactions contemplated by the Participation Agreement, dated as of August 12,
1986 (the Participation  Agreement),  among Burnham Leasing  Corporation,  a New
York  corporation,  as Owner  Participant,  The First National Bank of Boston, a
national banking association (FNB),  individually and as Owner Trustee, First PV
Funding Corporation,  a Delaware corporation,  Chemical Bank, a New York banking
corporation,  as Indenture  Trustee,  and PNM. All capitalized terms used herein
and not otherwise  defined herein shall have the meaning set forth in Appendix A
to the  Participation  Agreement.  This opinion is' being delivered  pursuant to
Section 11(a) (22) of the Participation Agreement.

                As such counsel we have examined originals or copies,  certified
or  otherwise  identified  to  our  satisfaction,  of  such  corporate  records,
agreements and other instruments, certificates, orders, opinions, correspondence
with public officials,  certificates of officers and representatives of PNM, and
other  documents,  as we have deemed  necessary or advisable for the purposes of
rendering the opinions set forth herein.




6091.BURNHAM.1106.08:1.





                In rendering  our  opinions,  we have also  reviewed the Special
Order of Exemption,  issued December 26, 1985, by the Arizona Department of Real
Estate  with  respect to PVNGS,  together  with two (2) Snell & Wilmer  petition
letters to the Arizona  Department of Real Estate,  dated  December 19, 1985 and
December 23, 1985 (the Special Order of Exemption and the petition letters being
collectively referred to herein as the "Exemption Documents").

                In rendering our opinions,  we have relied as to certain factual
matters on the documents we have examined,  on certificates of public officials,
and on the Certificate attached as Exhibit A, and we have assumed:

                (1) Lessee is a corporation  duly organized and validly existing
        in good  standing  under the laws of the State of New Mexico and has the
        corporate  power and  authority  to carry on its  business as  presently
        conducted,  to own or hold under lease its  properties and to enter into
        and perform its obligations under each Transaction  Document to which it
        is a party.

                (2) The  execution,  delivery and  performance by Lessee of each
        Transaction Document to which it is a party have been duly authorized by
        all  necessary  corporate  action on the part of Lessee and do not,  and
        will not, require the consent or approval of the stockholders of Lessee.

                (3) Each  Transaction  Document  to which  Lessee is a party has
        been duly  executed and delivered by Lessee,  and each such  Transaction
        Document  (excluding  the Facility  Lease) to which Lessee is a party is
        the legal, valid and binding obligation of Lessee,  enforceable  against
        Lessee in accordance with its terms.

                (4) Each party to each Transaction Document,  other than Lessee,
        is duly  organized and validly  existing in good standing under the laws
        of the jurisdiction of its organization, is duly registered, licensed or
        authorized to transact business in each other jurisdiction in which such
        registration,  licensing or authorization is required, and has the power
        and the  authority  to enter into and to perform its  obligations  under
        each Transaction 'Document to which it is a party.


                                       -2-

6091.BURNHAM.1106.08:1





                (5) The  execution,  delivery and  performance  by each party to
        each Transaction Document,  other than Lessee, have been duly authorized
        by all necessary  action by such party and do not require the consent or
        approval  of any of the  stockholders  of such party.  Each  Transaction
        Document  has been duly  executed and  delivered by each party  thereto,
        other  than  Lessee,  and  constitutes  the  legal,  valid  and  binding
        obligation of such party,  enforceable  against such party in accordance
        with its terms.

                (6) The trusts of which the Owner Trustee, the Indenture Trustee
        and the Collateral  Trust Trustee are the Owner  Trustee,  the Indenture
        Trustee and the Collateral Trust Trustee, respectively, were duly formed
        and are validly  existing under the laws of the  jurisdiction  governing
        such trusts.  Each of the Owner Trustee,  the Indenture  Trustee and the
        Collateral  Trust  Trustee has the power and  authority  under the trust
        agreement  for its  respective  trust to  enter  into  and  perform  its
        obligations under each Transaction Document to which it is a party.

                (7)  The  execution,  delivery  and  performance  by  the  Owner
        Trustee, the Indenture Trustee, and the Collateral Trust Trustee of each
        Transaction  Document to which it is a party are authorized by the trust
        agreement  of its  respective  trust and do not  require  the consent or
        approval of any other  Person.  Each  Transaction  Document to which the
        Owner Trustee,  the Indenture Trustee or the Collateral Trust Trustee is
        a party has been duly executed and delivered by the Owner  Trustee,  the
        Indenture  Trustee or the Collateral  Trust Trustee,  respectively,  and
        constitutes  the  legal,  valid  and  binding  obligation  of the  Owner
        Trustee,   the  Indenture  Trustee  or  the  Collateral  Trust  Trustee,
        respectively,  enforceable  against  the Owner  Trustee,  the  Indenture
        Trustee or the  Collateral  Trust Trustee,  respectively,  in accordance
        with its terms.

                (8) Lessee's past, present and proposed  activities in the State
        of  Arizona  (including,  without  limitation,  Lessee's  ownership  and
        operation of electrical  facilities in the State of Arizona) consist of,
        and are limited to, Lessee's ownership of an undivided interest in PVNGS
        (including the plant site) the ANPP Switchyard and associated


                                       -3-

6091.BURNHAM.1106.08:1





       transmission  facilities  therefor,  and its  ownership  interest in, and
       operation of a certain portion of, certain transmission lines, facilities
       and control  equipment  located on real  property  owned by Lessee and/or
       other  corporations  and  on  easements  owned  by  Lessee  and/or  other
       corporations  in Greenlee  County,  Arizona.  Lessee is not  making,  nor
       presently  proposing to make,  any sales of  electricity  in the State of
       Arizona (other than sales to or exchanges with other electric  generating
       or distributing entities).

                (9) The Owner Participant,  FNB, (in its individual capacity and
        as the Owner Trustee), and the Indenture Trustee, and each of them, will
        not, by reason either of entering into the Participation  Agreement, the
        Facility  Lease,  the Assignment and Assumption,  the Indenture,  or any
        other   Transaction   Document,   consummation   of   the   transactions
        contemplated  thereby or  otherwise,  engage in any  activity in Arizona
        involving the ownership  and operation of electrical  facilities,  other
        than those presently  conducted by the Lessee, as set forth in Paragraph
        8 above;

                (10)  Immediately  prior to the  execution  and  delivery of the
        Transaction  Documents,  Lessee owned the property to be  transferred by
        Lessee to Owner Trustee  under the  Transaction  Documents.  Immediately
        after the execution  and delivery of the  Transaction  Documents,  Owner
        Trustee  will own the  property to be  transferred  by the Lessee to the
        Owner Trustee under the Transaction  Documents.  The assumptions in this
        Paragraph  10 do not  apply to the  opinion  in the  first  sentence  of
        Section 9 of this legal opinion.

                (11) Amendment Number 10 to the ANPP Participation Agreement has
        been duly authorized,  executed and delivered by, constitutes the legal,
        valid and binding agreement of, and is enforceable against,  each of the
        parties  thereto.  The  transactions  contemplated  by  the  Transaction
        Documents are authorized and permitted to be performed  pursuant to, and
        do not  conflict  with,  the terms and  conditions  of any ANPP  Project
        Agreement,  including,  without  limitation,  Amendment Number 10 to the
        ANPP Participation Agreement.

6091.BURNHAN.1106.08:1





                (12) The sale and conveyance of the Undivided Interest, the Real
        Property  Interest  and any  other  property  or  interest  in  property
        transferred  by Lessee under the  Transaction  Documents will not render
        Lessee  insolvent  nor is it being  made in  contemplation  of  Lessee's
        insolvency;  the  property  remaining  in the hands of Lessee after such
        sale,  conveyance  and transfer is not an  unreasonably  small  capital;
        Lessee does not intend to or believe that it will incur debts beyond its
        ability  to pay as they  mature;  and  Lessee  has no  actual  intent to
        hinder, delay or defraud either present or future creditors.

                (13) On the date of execution of the  Transaction  Documents and
        on the date hereof,  there was adequate  consideration for the execution
        and  delivery by Lessee of the  Transaction  Documents  to which it is a
        party and for Lessee  entering  into the  transaction  described  in the
        Transaction Documents.

                (14) The chief executive office and the place of business of the
        Lessee and the office where it keeps its records concerning its accounts
        or  contract  rights  is  located  at  Alvarado  Square,   Albuquerque,.
        Bernalillo County, New Mexico 87158.

                (15) The  Transaction  Documents  accurately  and completely set
        forth all agreements,  arrangements  and  understandings  of the parties
        thereto with respect to the transaction described in and contemplated by
        the Transaction  Documents and the Transaction  Documents accurately and
        completely  reflect the  intentions  of the parties with respect to such
        transaction.

                  (16) The  Facility  Lease is a "lease" for Federal  income tax
         purposes  and an  "operating  lease"  and  not a  "capital  lease"  for
         financial reporting purposes under Financial Accounting Standards Board
         Statement 13 and will be so treated and  reported for such  purposes by
         Lessee and Owner Trustee.

                (17)  The  form  of  the  Transaction   Documents  executed  and
        delivered  by  the  parties  thereto  conforms  to  the  drafts  of  the
        Transaction Documents described above.

                Based on the  foregoing  and subject to the  qualifications  set
        forth herein, we are of the opinion that:

                (1) Lessee is  authorized  to transact  business  and is in good
        standing as a foreign  corporation under the General  Corporation Law of
        the State of  Arizona,  Chapter 1, Title 10,  Arizona  Revised  Statutes
        ("A.R.S.").

                (2) Lessee has the power and  authority,  and is not required to
        obtain any  franchises,  licenses or permits not  already  obtained,  to
        engage  in the State of  Arizona  in the  business  and  activities  now
        conducted  by  it  therein,   except  that  certain  minor  defects  and
        exceptions may exist which,  individually and in the aggregate, are not,
        in our judgment, material.

                (3) Lessee is not a public utility or public service corporation
        under Arizona Applicable Law.

                (4) Under Arizona Applicable Law the Owner Participant,  FNB (in
        its individual capacity and as Owner Trustee) and each of them, will not
        be, by reason of entering into any Transaction  Document or by reason of
        the activities  contemplated by the  Transaction  Documents prior to the
        expiration or termination of the Facility  Lease,  subject to regulation
        as a public  service  corporation,  public  utility,  or public  utility
        holding  company  by any  Arizona  public  utility  commission  or other
        Arizona  regulatory  body,   authority  or  group  (including,   without
        limitation, the Arizona Corporation Commission),  provided,  however, we
        express no opinion regarding the effect of (i) Applicable Law not now in
        effect,  (ii) any transfer of ownership of the Undivided Interest by the
        Owner Trustee, (iii) termination or expiration of the Facility Lease and
        the taking of  possession by the Owner Trustee or any other Person of an
        interest in Unit 2, (iv) Lessee's providing of transmission  services to
        the Owner Trustee or any other Person  owning the Undivided  Interest or
        the Real  Property  Interest,  or (v) any  exercise of remedies or other
        rights by any Person in connection with taking possession of an interest
        in Unit 2.

                (5) All  Governmental  Action  by the  State of  Arizona  or any
        political  subdivision thereof which is or will be required on or before
        the date hereof in connection  with the execution and delivery by Lessee
        of  each  Transaction  Document  to  which  Lessee  is a  party  and  in
        connection  with the  performance by Lessee of those of its  obligations
        pursuant to any  Transaction  Document to which  Lessee is a party which
        are to be  performed  on or  before  the date  hereof,  have  been  duly
        obtained, given or accomplished, except that our opinion in this Section
        5 does not relate to (i) any governmental  Action required in connection
        with construction, improvement, maintenance, use, possession, operation,
        decommissioning  or retirement  from service of any portion of Unit 2 or
        PVNGS or  otherwise  with  respect to Unit 2 or PVNGS or Lessee's or the
        Operating Agent's involvement therewith, Lessee's duties and obligations
        as a Participant under any of the ANPP Project  Agreements,  or Lessee's
        duties and  obligations as Agent under the  Assignment  and  Assumption;
        (ii) securities and taxation laws of any Arizona Governmental Authority;
        and (iii) the recording or filing of any Transaction Document;  and (iv)
        the  transfer  of the  "Assigned  Project  Agreements"  (as that term is
        defined in the Deed) pursuant to the Deed.

                (6) The execution,  delivery and  performance of the Transaction
        Documents by the parties  thereto do not violate the Atomic  Energy Act,
        as now in effect,  the NRC regulations  now in effect,  any order of the
        NRC now in effect, or the Nuclear Waste Act, as now in effect,  provided
        that such parties  comply with the terms and  conditions  of the License
        and the NRC Order. No Governmental  Action by or with respect to the NRC
        is or will be required in  connection  with the  execution,  delivery or
        performance  by  Lessee of the  Participation  Agreement,  the  Facility
        Lease, the Assignment and Assumption or any other  Transaction  Document
        to which it is a party,  except (i) such Governmental  Actions as may be
        required  pursuant to the terms of the License;  (ii) such  Governmental
        Actions as may be required pursuant to the terms of the NRC Order; (iii)
        such other  Governmental  Actions by or with  respect to the NRC as have
        been duly obtained,  given or accomplished on or before the date hereof;
        (iv) such  Governmental  Actions of or with respect to the NRC as may be

        required  under  existing law or  regulation  to be  obtained,  given or
        accomplished from time to time after the Closing Date in connection with
        the construction,  improvement,  maintenance, operation, decommissioning
        or  retirement  from  service  of any  portion  of  Unit 2 or  PVNGS  or
        otherwise  with respect to Unit 2 or PVNGS and Lessee's or the Operating
        Agent's involvement  therewith;  and (v) such other Governmental Actions
        as may be required under law or regulation not now in effect.

                (7) The  transfer of property and interest in property by Lessee
        to the Owner Trustee pursuant to the Participation  Agreement,  the Bill
        of  Sale,  the  Deed,  the  Trust  Assignment,  and the  Assignment  and
        Assumption is not a fraudulent  conveyance under the law of the State of
        Arizona,  provided,  however, that this opinion, in so far as it relates
        to  A.R.S.  Section  44-1061  and any  common  law  vendor-in-possession
        fraudulent  conveyance  doctrine,  is subject to the following comments.
        Section 44-1061 provides:

                         "A. A sale made by a vendor of goods  and  chattels  in
                         his  possession or under his control,  or an assignment
                         of goods and chattels, unless the sale or assignment is
                         accompanied by an immediate delivery and followed by an
                         actual and continued change of possession of the things
                         sold or  assigned,  is prima  facie  evidence  of fraud
                         against  creditors  of the vendor,  or creditors of the
                         person making the assignment,  or subsequent purchasers
                         in good faith.

                         "B. The term  'creditors'  includes all persons who are
                         creditors  of the vendor or  assignor at any time while
                         such goods and chattels are in his  possession or under
                         his control."

                The Arizona court decisions  interpreting  Section 44-1061 arose
        in the context of  tangible  property  in the actual  possession  of the
        seller.  These  decisions  suggest  that open,  visible and  unequivocal
        indications that there has been a change


                                       -8-

6091.BURNHAM.1106.08:l





       of ownership  would be  sufficient to overcome the prima fade evidence of
       fraud established by Section 44-1061. See, e.g., Nolte V. Winstayley,  16
       Ariz. 327, 145 Pac. 246 (1914). Unfortunately, this precedent is not very
       helpful in the context of the present transaction. In addition, the court
       decisions  under  Section  44-1061  are  equivocal  as to the  effect  of
       recording or filing transfer documents.  Nolte V. Winstanley,  supra; and
       Liebes V. Steffy,  4 Ariz. 11, 32 Pac. 261 (1893).  Notwithstanding  this
       equivocation,  as to a subsequent  encumbrancer of any personal  property
       which is subject to Article 9 of the Uniform Commercial Code as in effect
       in  Arizona,  which  is  described  in  the  three  (3)  UCC-1  Financing
       Statements,  dated December 31, 1985 between Lessee, as lessee, and Owner
       Trustee,  as lessor filed with the  Secretary of State of Arizona and the
       County  Recorder,  Maricopa  County,  State of Arizona  (Lease  Financing
       Statements)  and in which a security  interest may be perfected by filing
       of a financing  statement  within Arizona,  we believe that the filing of
       the Lease Financing Statements should be sufficient to overcome the prima
       facie evidence of fraud to the extent the description of such property in
       the  Lease  Financing  Statements  is  accurate,  complete,  and  legally
       adequate.  In addition,  as to future  creditors with actual knowledge of
       the transfers in the Deed, the Bill of Sale, the Trust Assignment and the
       Assignment  and  Assumption  prior to extending or  committing to extend.
       credit,  we believe that such knowledge  should  overcome the prima facie
       evidence of fraud in Section 44-1061.

                (8)  Neither  the  execution  and  delivery  by Lessee,  nor the
        performance  by Lessee,  of any  Transaction  Document  to which it is a
        party, conflicts with, or results in a breach of any statute, ordinance,
        governmental  rule or  regulation  of the State of Arizona  or  Maricopa
        County,  except  that our  opinion  does not relate to any  conflict  or
        breach as a result of (i) construction,  improvement,  maintenance, use,
        possession, operation, decommissioning or retirement from service of any
        portion of Unit 2 or PVNGS or otherwise  with respect to Unit 2 or PVNGS
        or the Lessee's or the operating Agent's involvement therewith, Lessee's
        duties and  obligations  as a Participant  under any of the ANPP Project
        Agreements,  or  Lessee's  duties  and  obligations  as Agent  under the



                                       -9-

6091.BURNHAM.1106.08:1




        Assignment and Assumption;  (ii) Applicable Law not now in effect; (iii)
        securities  and  taxation  laws of any Arizona  Governmental  Authority;
        ((iv) any  Refunding  described  in  Section  2(c) of the  Participation
        Agreement,  any  assumption  by Lessee  pursuant  to Section  3.9 of the
        Indenture or any other similar or related  provision in the Indenture or
        any of the other  Transaction  Documents,  a transfer of the interest in
        the Trust  Estate  pursuant  to  Section  7(b) (4) of the  Participation
        Agreement  and any security  interest  granted  pursuant to said Section
        7(b)(4),  the conversion of the Facility  Lease to a security  agreement
        pursuant  to  Section  9(c),  Section  9(d),  or  Section.  16(e) of the
        Facility  Lease  or any  other  similar  or  related  provisions  in the
        Facility Lease or any of the other Transaction Documents, the subjection
        of the Undivided  Interest or the Real Property  Interest to the lien of
        the  Indenture  pursuant  to Section  9(j) of the  Facility  Lease,  any
        Supplemental  Financing  pursuant to Section 8(f) of the Facility Lease,
        or the  transfer  of the  Assigned  Project  Agreements  pursuant to the
        Deed;] (v) any action taken by Lessee  pursuant to Section  10(b) (2) of
        the   Participation   Agreement   or  any  similar   provision   in  the
        Participation  Agreement  or any other  Transaction  Document;  (vi) any
        involvement  by Lessee in  connection  with any transfer of ownership of
        the  Undivided  Interest  or the Real  Property  Interest  by the  Owner
        Trustee or the taking of  possession  of the  Undivided  Interest or the
        Real  Property  interest  by Owner  Trustee  or any  other  Person  upon
        expiration or termination of the Facility Lease;  (vii) Lessee providing
        transmission  services for the Owner  Trustee or any other Person owning
        the Undivided Interest or the Real Property Interest or ceasing to serve
        as Agent pursuant to the Assignment or Assumption,  (viii) any action by
        Lessee pursuant to Article VI of the Assignment and Assumption,  or (ix)
        Lessor or any other Person, other than Lessee,  receiving the Generation
        Entitlement Share of Lessee pursuant to Section 19 of the Facility Lease
        or any other provision of any Transaction Document.

                 (9) Assuming  that any choice of law  provision in favor of the
        law of a state other than the State of Arizona is  disregarded  therein,
        the Deed,  the Bill of Sale and the  Assignment  and  Assumption  are in
        sufficient  form to convey from Lessee to Owner Trustee the interests in
       


                                      -10-

6091.BURNHAM.1106.08:1




        property  described therein and for recording under the law of the State
        of  Arizona,  except  that  our  opinion  in  this  sentence  and in the
        remainder  of this  Section  9 does not  relate to the  transfer  of the
        Assigned Project  Agreements  pursuant to the Deed. The Trust Assignment
        is in  sufficient  form to  convey  from  Lessee  to Owner  Trustee  the
        interests in property therein described. The Deed, the Bill of Sale, the
        Assignment  and  Assumption  and the Facility  Lease when duly executed,
        acknowledged  and delivered,  each must be recorded in the Office of the
        Recorder of Maricopa  County,  Arizona,  together  with an [Affidavit of
        Legal Value] pursuant to A.R.S. Section 42-1612 with respect to any such
        document  transferring  title  to real  estate  (other  than  leases  or
        easements).   Precautionary  financing  statements  pursuant  to  A.R.S.
        Section 47-9408 must be filed in the office of the Arizona  Secretary of
        State and the Office of the Recorder of Maricopa County,  Arizona.  Upon
        the  completion  of such  recordings  and filings,  no other  filings or
        recordings in Arizona are required to establish,  preserve, perfect, and
        protect the Owner  Trustee's  rights and interests  (including,  without
        limitation1  any security  interest which may be deemed to be created by
        the  Facility  Lease)  in and to the  Undivided  Interest  and the  Real
        Property  Interest  (other  than the  interests  transferred  under  the
        Assignment of Beneficial  Interest),  and no additional  recordation  is
        required to continue the effectiveness of such recordings, provided that
        our opinion in this  Section 9 is limited to property  constituting  the
        Undivided  Interest and the Real  Property  Interest that is either real
        property  under the law of the State of Arizona or  property  subject to
        Article 9 of the  Uniform  Commercial  Code (as in effect in Arizona) in
        which a security  interest may be perfected by the filing of a financing
        statement  within  the State of  Arizona.  In  addition,  no  additional
        financing statements, other than those filed with the Secretary of State
        of Arizona and in the Office of the County Recorder of Maricopa  County,
        Arizona, are required to be filed in order to continue the effectiveness
        thereof  except that  continuation  statements  are required to be filed
        with respect to such financing  statements  within each of the six-month
        periods  preceding  the  expiration  of each  six-year  period after the
        respective dates of filing. We express no opinion regarding the form


                                      -11-

6091.BURNHAM.1106.08:1





       for  conveyance,  the transfer or the perfection of rights in any Capital
       Improvements  or  regarding  filings or  recordings  that may be required
       under the laws of any other state,  under federal law or by reason of the
       application  of the  conflict  of laws rules set forth in A.R.S.  Section
       47-9103. To the extent any recorded or filed Transaction  Document refers
       to or  incorporates  by reference  any other  Transaction  Document  (for
       definitional  purposes or  otherwise)  not  recorded or filed in the same
       location  or,  if  recorded  [or]  filed,  not  identifying  the date and
       instrument or file number of such document incorporated by reference, our
       opinion in this Section 9 excludes the effect,  if any, of such reference
       or incorporation by reference. In giving our opinion in this Section 9 we
       have assumed that the description of the Undivided  Interest and the Real
       Property Interest in the Lease Financing Statements is accurate, complete
       and legally adequate.

                (10) You have  requested  that we advise you  whether an Arizona
        court would give effect to the choice of law  provision  in favor of the
        law of the State of New York in each  Transaction  Document,  other than
        the Deed,  the Bill of Sale,  the Trust  Assignment,  the Assignment and
        Assumption,  and the  Facility  Lease.  There is no Arizona case stating
        that an Arizona  court will  follow the choice of law  provision  of the
        parties  to a  contract.  However,  the  Supreme  Court of  Arizona  has
        consistently  ruled that where it is not bound by a previous decision or
        by legislative enactment it will follow the rules in the Restatements of
        the Law including the Restatements of Conflict of Laws. Smith v. Normat,
        51 Ariz. 134, 75 P.2d 38 1938);  Western Coal & Min. Co. V. Hilvert,  66
        Ariz. 171, 160 P.2d 331 (1945); and Taylor V. Security National Bank, 20
        Ariz.  App.  504,  514 P.2d 257 (1973).  Section 187 of the  Restatement
        (Second)  Conflict of laws  provides  that the parties to a contract may
        stipulate  to their  choice of law t9 govern the  contract  and that the
        laws of the state chosen will be applied unless (i) the particular issue
        is one  which  the  parties  could  not  have  resolved  by an  explicit
        provision in their agreement directed to that issue, and (ii) either:




                                      -12-

6091.BURNHAM.1106.08:1




                         "(a) the chosen state has no  substantial  relationship
                         to the parties or the transaction and there is no other
                         reasonable basis for the parties' choice; or

                         "(b)  application  of the law of the chosen state would
                         be  contrary to a  fundamental  policy of a state which
                         has a materially greater interest than the chosen state
                         in the determination of the particular issue and which,
                         under the rule of  Section  188,  would be the state of
                         the  applicable  law in  the  absence  of an  effective
                         choice of law by the parties."

                We  believe  that  the  State  of New  York  has a  "substantial
        relationship"  to the  parties or the  transaction  with  respect to the
        documents covered by the opinion in this Section 9 and that with respect
        to such documents  there is a reasonable  basis for the choice of law of
        the  State  of New York  because  at least  one of the  parties  to such
        documents  is located in the State of New York and such  documents  have
        been substantially  negotiated within and from the State of New York and
        have been executed and delivered within the State of New York. Thus, the
        effectiveness  of the choice of law  provisions in these  documents will
        depend upon whether,  as to the particular issue in question,  (i) there
        would be a difference in the applicable  substantive law of the State of
        New  York,  on the one  hand,  and the law of the  State of  Arizona  or
        another  state1 on the other  hand,  (ii) the  resolution  of such issue
        under  the  law  of the  State  of  New  York  would  be  contrary  to a
        fundamental  policy of the State of Arizona or such other  state,  (iii)
        the State of Arizona or such other state would have a materially greater
        interest  than  the  State  of  New  York  in the  determination  of the
        particular issue and (iv) under Section 188 of the Restatement  (Second)
        Conflict  of Laws,  the law of the State of Arizona or such other  state
        would be the applicable law.

                (11)  Assuming  an Arizona  court were not to give effect to the
        choice of law provision in the Facility Lease in favor of the law of the
        State of New York and  were to  apply  the law of the  State of  Arizona

        (other  than  choice of law  rules),  the  Facility  Lease is the legal,
        valid, and binding obligation of Lessee and is duly enforceable  against
        Lessee in accordance with its terms:

                         (a)  Except  as  limited  by   applicable   bankruptcy,
                insolvency,  moratorium,  reorganization,  and  similar  laws of
                general application;

                         (b)  Except  as  limited  by  equitable  principles  of
                general application; and

                           (c)  Except as limited  by other  applicable  laws or
                general principles of law that may render unenforceable  certain
                provisions of the Facility Lease, provided, however, that (i) if
                Owner  Trustee  does  not  violate  its  obligations  under  the
                Facility Lease (including,  without limitation,  the covenant of
                quiet  enjoyment),  such limitations will not interfere with the
                enforcement by Owner Trustee of the obligations of Lessee to pay
                Basic Rent as provided in Section 3(a) of the Facility  Lease as
                the payments of Basic Rent become due on each Basic Rent Payment
                Date prior to  termination  of the  Facility  Lease and  without
                acceleration  or advancement  thereof and (ii) Owner Trustee may
                obtain  the  return  of the  Undivided  Interest  and  the  Real
                Property interest upon termination or expiration of the Facility
                Lease,  except  in the  case of each  of (i)  and  (ii)  for the
                economic  consequences of any procedural  delays that may result
                from such limitations.

                Anything in this  opinion to the  contrary  notwithstanding,  we
express no opinion  concerning (i) the ownership of, or legal or equitable title
to, any  property,  (ii) whether the property  described  and referred to in the
Transaction  Documents  is  personal  property  or real  property or whether any
severance or other  provision in the  Transaction  Documents  purporting to make
certain property  personal  property is effective,  or (iii) the priority of the
interest of any person in any property or interest in property.

To Each Person Listed on The Attached Schedule

                   SALE AND LEASEBACK OF AN UNDIVIDED INTEREST
                 IN PALO VERDE NUCLEAR GENERATING STATION UNIT 2
                          AND CERTAIN COMMON FACILITIES


Dear Sirs:

                We have acted as Special FERC counsel for Public Service Company
of  New  Mexico,  a  New  Mexico   corporation  (PNM)  in  connection  with  the
transactions contemplated by the Participation Agreement, dated as of August 12,
1986 (the Participation  Agreement),  among Burnham Leasing  Corporation,  a New
York corporation (the Owner  Participant),  The First National Bank of Boston, a
national  banking  association,  individually  and as  Owner  Trustee,  First PV
Funding Corporation,  a Delaware corporation,  Chemical Bank, a New York banking
corporation, as Indenture Trustee and PNM. All capitalized terms used herein and
not  otherwise  defined  shall have the  meanings set forth in Appendix A to the
Participation  Agreement.  This opinion is being  delivered  pursuant to Section
11(a)(23) of the Participation Agreement.

                As such counsel we have examined originals or copies,  certified
or  otherwise  identified  to  our  satisfaction,   of  all  corporate  records,
agreements and other instruments, certificates, opinions and correspondence with
public officials, certificates of officers and representatives of PNM, and other
documents as we have deemed necessary or advisable for the purposes of rendering
the opinions set forth herein.




6091.BURNHAM.1106.08:1





                As to matters of fact  relevant to our  opinion,  we have relied
upon the  representations  of the  parties  as set  forth  in the  Participation
Agreement,  including the  supporting  documentation  related  thereto and PNM's
October 18, 1985 petition to the FERC for an order (1) disclaiming  jurisdiction
over its proposed  sale and  leaseback of a portion of its interest in Unit 1 of
the Palo Verde Nuclear Generating Station, (2) disclaiming jurisdiction over the
Equity  Investors and Lessors of such  interest,  and (3)  determining  that the
Owner  Participants  and Lessors would not become public utilities as defined in
Section  201(e) of the Federal  Power Act,  16 U.S.C.  824(e)  (1982)  solely by
reason of their  participation in the proposed sale and leaseback  arrangements.
We have also  relied  upon the  requested  FERC Order  Disclaiming  Jurisdiction
issued on December 5, 1985.

                Based on the foregoing, we are of the opinion that:

                           (a) So long as the Lease shall be in effect,  neither
                the Owner  Participant nor the Owner Trustee will be or become a
                "public  utility"  within the  meaning of Section  201(e) of the
                Federal Power Act, 16 U.S.C. 824(e) (1982),  solely by reason of
                its  participation  in  the  transactions  contemplated  by  the
                Participation Agreement; and

                           (b) PNM does not  require  authorization  pursuant to
                Section  203(a) of the Federal  Power Act, 16 U.S.C.  ss.824b(a)
                (1982),  to sell the interest  contemplated by the Participation
                Agreement  to  the  Trust  in  accordance  with  the  terms  and
                conditions set forth in the Participation Agreement.

                There are no court  cases on point with  respect to our  opinion
expressed  in  paragraph  (a).  However,  the  FERC  and  its  predecessor  have
consistently  found that it would be inconsistent with the intent of the Federal
Power Act for it to find that investors or trustees  participating  in financing
transactions similar to those contemplated by the Participation  Agreement would
be public  utilities  under  Section  201(e) of the Federal Power Act, 16 U.S.C.



                                       -2-
6091.BURNHAM.1106.08:1




824(e)  (1982)  solely by reason of such  participation,  a finding  in which we
concur.  The FERC previously made such a finding with respect to PNM's sale of a
part of its ownership  interest in Palo Verde Nuclear  Generating Station Unit 1
in its  December 5, 1985 order.  The most  recent FERC order  containing  such a
finding related to El Paso Electric  Company's proposed sale of all or a portion
of its ownership interest in Palo Verde Nuclear Generating Station Unit 2.

                We express no opinion as to the status of' the Owner Participant
or the Owner Trustee upon  termination of the Lease,  the occurrence of an Event
of Default,  or the  occurrence of any  circumstance  or event whereby the Owner
Trustee  or the  Owner  Participant  may be in  possession  of, or  control  the
operation of, the Undivided Interest or any interest therein. We also express no
opinion  as to  any  other  aspects  of  the  transactions  contemplated  by the
Participation  Agreement that are governed by any statute other than the Federal
Power Act.

                                       Very truly yours,

To Each Person Listed on The Attached Schedule


                 SALE AND LEASEBACK 0F AN UNDIVIDED INTEREST IN
                  PALO VERDE NUCLEAR GENERATING STATION UNIT 2
                          AND CERTAIN COMMON FACILITIES

Dear Sirs:

                We have acted as special  Arizona  counsel for  Burnham  Leasing
Corporation,  a New York corporation (the Owner Participant,  in connection with
the transactions contemplated by the Participation Agreement, dated as of August
12, 1986 (the  Participation  Agreement),  among Public  Service  Company of New
Mexico,  a New Mexico  corporation  (PNM),  The First National Bank of Boston, a
national banking association (FNB), individually and as Owner Trustee (the Owner
Trustee), First PV Funding Corporation, a Delaware corporation, Chemical Bank, a
New York banking  corporation,  as Indenture  Trustee,  and PNM. All capitalized
terms used herein and not otherwise  defined  herein shall have the meanings set
forth in  Appendix  A to the  Participation  Agreement.  This  opinion  is being
delivered pursuant to Section 11(a) (24) of the Participation Agreement.

                As such counsel we have examined originals or copies,  certified
or  otherwise  identified  to  our  satisfaction,  of  such  corporate  records,
agreements and other instruments, certificates, orders, opinions, correspondence
with public officials,  certificates of officers and representatives of PNM, and
other  documents,  as we have deemed  necessary or advisable for the purposes of
rendering the opinions set forth herein.




6091.BURNHAM.1106.08:1





                Certain  facts  particularly  relevant  to  our  opinion  may be
summarized as follows. The proposed transaction contemplates the sale of part of
PNM's  undivided  10.2%  interest in Unit 2 and certain common  facilities  (the
Facilities) to the Owner Trustee for the Owner  Participant.  The Owner Trustee,
will lease the purchased  interest in the Facilities  back to PNM on a long-term
net lease basis.  The purchase of PNM's  interest in the Facilities by the Owner
Trustee  will be  financed  in part by a loan made by the Loan  Participant  and
evidenced by a  non-recourse  obligation  (the Initial Series Note) of the Owner
Trustee.

                The  Initial  Series  Note  will be  issued by FNB under a lease
indenture,  for which  Chemical Bank will serve as Indenture  Trustee.  Upon the
closing of the lease  indenture,  the  Initial  Series  Note will be pledged and
assigned to the Collateral  Trust  Trustee.  The Initial Series Note will not be
secured by the property  subject to the Lease, but instead will be secured by an
assignment of the rights of the Owner Trustee, as lessor, to receive rentals and
certain other payments under the Lease with PNM.

                First PV  Funding  Corporation,  as the Loan  Participant,  will
obtain  funds for the  purchase of the Initial  Series  Note by  borrowing  from
commercial  banks under a Term Loan Agreement and, in connection  therewith,  by
the sale of debt securities.

                Based on the sale and leaseback transaction as described in this
letter, and as qualified below, we are of the opinion that:

                           (i)  the transaction will not be a fraudulent 
                conveyance under Arizona law;

                           (ii) the Trust will not be subject to regulation as a
                public   service   corporation   by  the   Arizona   Corporation
                Commission, at least unless and until the Trust actually assumes
                possession of the Facilities;

                           (iii) the Conveyance Documents, as identified below,
                are sufficient under Arizona law to convey such title as PNM has
                in the Facilities; and

                           (iv)  Arizona law does not  prohibit  FNB or Chemical
                Bank from serving,  respectively,  as Owner Trustee or Indenture
                Trustee and does not require  either  bank,  based solely on its
                involvement in the Palo Verde sale and leaseback,  to qualify to
                do business in Arizona.

                These conclusions are based on our understanding of the sale and
leaseback  transaction  as stated in this letter and our analysis of authorities
deemed by us to be analogous or otherwise relevant and briefly described in part
below.

                1.      Fraudulent Conveyance.

         We  understand  that:  (i) before the  closing of the  transaction,  an
independent  appraisal will confirm that the aggregate purchase price to be paid
for the Facilities is a reasonable estimate of their fair market value, and (ii)
the proposed sale and leaseback as described in the  Transaction  Documents will
be  approved  pursuant  to a  Final  Order  of the  New  Mexico  Public  Utility
Commission (the "Final Order") and (ii;) such  transactions  will not render PNM
insolvent or otherwise impair its financial condition.

                Our  review of Arizona  statutes  and case law has  revealed  no
authorities  that  directly  address a sale and  leaseback  and suggest that the
proposed  transaction  would be prohibited or fraudulent.  Moreover,  we believe
that the transfer of PNM's interest in PVNGS as contemplated  would be for "fair
consideration"  within the meaning of Arizona's  Fraudulent  Conveyance  Act and
therefore  would not be  fraudulent  under  Ariz.  Rev.  Stat.  Section  44-1004
(conveyance  without fair consideration  rendering  transferor  insolvent) ; id.
Section 44-1005  (conveyance  without fair  consideration  leaving transferor in
business with unreasonably  small capital);  or id. Section 44-1006  (conveyance
without fair consideration by transferor about to incur debts).

                Arizona case law indicates that even if a conveyance is for fair
consideration, it may be found fraudulent under Ariz. Rev. Stat. Section 44-1007
if made with actual intent -- as distinguished from an intent presumed at law --
to hinder, delay or defraud creditors.  Wallin v. Scottsdale Plumbing Co., Inc.,

                                       -3-

Ariz.  App.  591,  557 .P.2d 190  (i976).  We note  that the  proposed  sale and
leaseback will have been reviewed and approved in at least two public regulatory
hearings.  Based on our review of Arizona law and the facts as described, we see
no basis for a successful  claim that the transaction  involves an actual intent
to defraud PNM's creditors.

                Arizona also has a venerable statute that predates statehood and
adoption of the Fraudulent Conveyance Act and provides that:

                A sale made by a vendor of goods and chattels in his  possession
or under his control, or an assignment of goods and chattels, unless the sale or
assignment is accompanied by an immediate delivery and followed by an actual and
continued  change of  possession  of things  sold or  assigned,  is prima  facie
evidence of fraud  against  creditors of the vendor,  or creditors of the person
making the assignment,  or subsequent purchasers in good faith. Ariz. Rev. Stat.
Section 44-1061.A.

                Our  research  has  not  revealed  any  reported  Arizona  court
decision  in the last fifty years that  relies  upon this  statute.  The few old
cases applying the statute make clear that failure of immediate  delivery is not
conclusive that a sale was fraudulent.  Instead, the statute is held to create a
presumption  of fraud that may be overcome by proof that a transfer  was made in
good faith and for fair consideration. Nolte v. Winstanley, 16 Ariz. 327, 145 P.
246 (1914);  Liebes V.  Steffy,  4 Ariz.  11, 32 P. 261  (1893).  If the statute
applies to the  proposed-sale  and leaseback,  it would seem  relatively easy to
rebut the presumption of fraud under the circumstances.

                Moreover,  we believe that there are  plausible  arguments  that
Ariz.  Rev. Stat. ss.  44-1061.A does not apply to the sale of PNM's interest in
the  Facilities.  Although  Arizona cases provide little  guidance on the issue,
such an interest  arguably is not "goods and chattels" within the meaning of the
statute.  We note in this regard that, even if the interest being transferred is
characterized  as  involving  in part  "personal  property,"  Arizona by statute
defines  personal  property to include  interests other than goods and chattels.
Ariz. Rev. Stat. ss. 1-215.25. Thus, even if PNM's interest in PVNGS is not real
property, such interest would not necessarily constitute "goods and chattels."

                                       -4-

6091.BURNHAM.1106.08:l







                The  few  reported  Arizona  cases  applying  Ariz.  Rev.  Stat.
ss.44-1061.A  also do not foreclose an argument that  "delivery" will in fact be
made under the  circumstances  of the  transaction.  We note in this regard that
ownership  of  PVNGS is  governed  by the ANPP  Participation  Agreement,  which
provides that Arizona Public  Service  Company is authorized to act as agent for
the owners of PVNGS,  and has  responsibility  and  control  over  construction,
operation, and maintenance of PVNGS.

                Gant  v.  Broadway,  2  Ariz.  315,  15  P.  862  (1887),  which
considered a predecessor statute to Ariz. Rev, Stat. ss. 44-1061.A,  states that
the acts  which  constitute  delivery  will  depend  upon the  character  of the
property sold and the circumstances of each particular case. More  specifically,
Gant  approved a jury  instruction  indicating  that where  property  remains in
possession of a third party,  "delivery"  can in some  circumstances  take place
when the  vendor,  purchaser,  and third  party  agree  that the goods  shall be
subsequently  held for the purchaser.  Whether Gant would guide an Arizona court
in applying  Ariz.  Rev.  Stat.  ss.44-1061.A  is  unclear,  because the statute
considered in that case differs  textually from the current statute,  i.e. ~ the
earlier statute provided for a conclusive presumption of fraud and did not refer
to assignment, and later cases apparently have not discussed Gant.

                Based on Gant,  one could  argued that any  required  "delivery"
will occur with  respect to the  transfer  of PNM's  undivided  interest  in the
Facilities because of the unusual nature of the property  transferred,  the fact
that the  transaction  will have been  subjected to prior review and approval in
public  regulatory  hearings,  and the  seemingly  indisputable  point  that the
transaction simply does not involve the sort of surreptitious  transfer that the
statute  intends to reach.  Whether Arizona courts would be receptive to such an
argument is difficult to predict, given the paucity of cases applying Ariz. Rev.
Stat. Section 44-1061.A.

                2.      Arizona Utility Regulation.

                Based  on our  review  of  the  Participation  Agreement,  other
Transaction Documents,  and the ANPP Participation  Agreement, as amended, we do
not believe that the Trust will become subject to Arizona utility

                Section  40-284.A of the Ariz.  Rev.  Stat.  prohibits a foreign
corporation  from  transacting  "public  service  business"  in  Arizona  unless
authorized to do so. Moreover, Ariz. Rev. Stat. ss. 40-284.B prohibits a

        "license,  permit or  franchise to own,  control,  operate or manage any
        public service business [from being) granted or transferred, directly or
        indirectly,  to any foreign corporation not lawfully  transacting within
        this state a public service business of like character."

Violation  of the  provisions  regulating a foreign  corporation  with regard to
transacting  a  public  service  business  can  result  in  criminal  and  civil
liability.

                Arizona law indicates that the provisions of Ariz.  Rev. Stat. ~
40-284  will  not  apply  to the  Trust as a  result  of the  proposed  sale and
leaseback because PNM is not a public service  corporation,  nor is it currently
transacting  "public service  business" within Arizona (for which conclusions we
rely on the  opinion  of Snell & Wilmer of even  date)  and the Trust  will not,
during the term of the Facility Lease, transact such business in this state.

                The Arizona  Constitution defines public service corporations to
include corporations  "furnishing  electricity for light, fuel or power" without
expressly  indicating  whether the electricity must be provided to the public in
Arizona.  The  constitutional   provision  empowering  the  Arizona  Corporation
Commission to regulate rates and charges of public service  corporations extends
that power only to services rendered to the public in Arizona.  Arizona statutes
and case law conform to this limitation.




                                       -6-
6091.BURNHAM.1106.08:1





                Because PNM is not now operating as a public service corporation
in Arizona in connection with its interest in PVNGS under the ANPP Participation
Agreement and in any event will retain control,  at least until default or other
termination of the Facility Lease, of its Arizona business,  we believe that the
proposed sale and leaseback will not violate Ariz.  Rev. Stat.  Section  40-284.
Moreover,  because the Trust will not furnish electricity for sale to the public
in Arizona  during the term of the  Facility  Lease,  we believe  that the Owner
Trustee and the Owner  Participant  will not be subject to  regulation as public
service corporations by the Arizona Corporation Commission. If the Owner Trustee
did take possession, depending upon the manner and then current structure of the
ANPP Participation  Agreement, it is possible that the Trust could then become a
public service corporation subject to regulation by the Corporation Commission.

                3.      Sufficiency of the Documents to Convey Title.

                Subject  to  the  assumptions,   exceptions  and  qualifications
expressed below, we are of the opinion that the Deed, the Deed and Bill of Sale,
and the Deed and Assignment of Beneficial Interest (all of the above instruments
being  collectively  referred to herein as the  "Conveyance  Documents") of even
date herewith  executed in connection with the transaction,  each of which names
PNM as  grantor  and FNB in its  capacity  as  Owner  Trustee  as  grantee,  are
sufficient under Arizona law to convey to FNB as Owner Trustee all of the right,
title and interest of PNM in and to the real and personal property  constituting
the Facilities and as identified in the Conveyance Documents.

                Our opinion is subject to the following assumptions,  exceptions
and  qualifications.  We assume that each of the Conveyance  Documents has been:
duly  authorized  and  executed  by  appropriate  action of each of the  parties
thereto;  duly delivered by PNM; and filed or recorded in the appropriate public
records.  We express no opinion as to the condition of title or  concerning  the
nature or existence  of the  interest of PNM in the real and  personal  property
constituting  the Facilities and as identified in the Conveyance  Documents.  We
note that the  Conveyance  Documents do not convey any portion of PNM's interest
in certain common facilities of PVNGS, certain ANPP Project Agreements,  and the


                                       -7-
6091.BURNHAM.1106.08:1




Unit 2 Retained  Assets,  and  certain  warranties  related  to the  Facilities.
Finally,  we are assuming that an appropriate  amendment of the trust disclosure
affidavit  relating to Title USA Trust No. 530 will be recorded under Ariz. Rev.
Stat.  ss. 33-401 with respect to the transfer  under the Deed and Assignment of
Beneficial Interest.

                4. Activities of the Owner Trustee and the Indenture Trustee.

                Our research  has  revealed no Arizona  statute or case law that
would prohibit FNB or Chemical Bank from serving, respectively, as Owner Trustee
or Indenture Trustee in the proposed transaction merely because of its status as
an  out-of-state  bank.  Moreover,  we do not  believe  that either bank will be
required,  solely  as  result  of its  participation  in the sale and  leaseback
transaction, to qualify to do business in Arizona.

                Our conclusion in this regard is qualified as follows. First, we
understand  that the Trust for which FNB will serve as trustee and the indenture
trust for which  Chemical Bank will serve as trustee will be formed  exclusively
for the purpose of the lease  financing of the Palo Verde  transaction.  Second,
the Owner Participant has informed us and we assume,  that the Owner Participant
has no interest in property located in Arizona except its beneficial interest as
Owner Participant in the assets held by the Trust and that the Owner Participant
engages  in no  business  or other  activities  within  this  state,  except the
activities contemplated by the Participation Agreement.  Third, FNB and Chemical
Bank  have  participated  previously  in four  sale and  leaseback  transactions
substantially  similar to that contemplated by the  Participation  Agreement and
may participate in a limited number of substantially similar transactions in the
future with respect to interests in PVNGS.  Fourth,  we do not offer any opinion
whether  activities  of Chemical  Bank or FNB within this state not described in
this letter  would  require  either bank to qualify to do business in this state
when considered  along with  participation in the Palo Verde sale and leaseback.
Finally, we do not offer any opinion whether qualification would be necessary if
the Owner Participant or either bank, in its capacity as trustee, assumed actual
possession of any portion of PVNGS upon default by PNM or upon other termination
of the  Facility  proposed  sale and  leaseback  and the  property is located in
Arizona.

6091.BURNHAM.1106.08:l





                Apart from the case law described  above,  Ariz.  Rev. Stat. ss.
l0-106.B  provides that,  "(without  excluding  other  activities  which may not
constitute transacting business in this state, foreign corporations shall not be
considered to be transacting business by reason of carrying on in this state any
one or more of the  following  activities."  The  specified  activities  include
"(creating  as a borrower or lender,  or acquiring,  indebtedness,  mortgages or
other security interests in real or personal property, "id. ss. 44-106.B.7,  and
"[s]ecuring or collecting debts or enforcing any rights in property securing the
same," Id. ss. 44-106.B.8.

                Our research has revealed no reported  Arizona  cases that apply
the statutory  provisions  described in the preceding paragraph in circumstances
that are directly on point with respect to the proposed sale and  leaseback.  At
the same time,  we note that  Arizona  case law does pot suggest  the  statutory
provisions will be applied other than in accord with their plain language.  That
language,  we believe,  indicates that certain  actions by FNB and Chemical Bank
will not constitute transacting business within Arizona.

         The  statutory  provisions  indicate  that FNB will not be  transacting
business  in the state by virtue of its  issuance  of the  Initial  Series  Note
secured by assignment of the lease payments because this action,  even if deemed
to be carried on in Arizona, involves the creation as a borrower of indebtedness
or other security interests in real or personal property. We note in this regard
that Arizona case law indicates  that the right to future  payments under a real
property lease is an incorporeal  hereditament  that constitutes and interest in
land.  Valley National Bank v. Avco  Development Co., 14 Ariz. App. 56, 480 P.2d
671 (1971).

                The statutory  provisions  also suggest that  Chemical  Bank, as
Collateral  Trust Trustee,  will not be transacting  business  within Arizona by
virtue of its  acceptance  of the  Initial  Series  Note or its  receipt  of the
assigned rental payments because these actions constitute securing or collecting
debts or enforcing any rights in property securing the same.

Assets,  and  certain  warranties  related to the  Facilities.  Finally,  we are
assuming  that  an  appropriate  amendment  of the  trust  disclosure  affidavit
relating to Title USA Trust No. 530 will be recorded  under Ariz.  Rev.  Stat. ~
33-401 with respect to the transfer  under the Deed and Assignment of Beneficial
Interest.

                4.  Activities of the Owner Trustee and the Indenture Trustee.

transaction, to qualify to do business in Arizona.

                Our conclusion in this regard is qualified as follows. First, we
understand  that the Trust for which FNB will serve as trustee and the indenture
trust for which  Chemical Bank will serve as trustee will be formed  exclusively

                          AND CERTAIN COMMON FACILITIES
Dear Sirs:

                We have acted as special New Mexico counsel for Burnham  Leasing
Corporation, a New York corporation (the Owner Participant),  in connection with
the transactions contemplated by the Participation Agreement, dated as of August
12, 1986, (the Participation Agreement),  among the Owner Participant, The First
National Bank of Boston,  a national  banking  association,  individually and as
Owner Trustee,  First PV Funding Corporation,  a Delaware corporation,  Chemical
Bank, a New York banking  corporation,  as Indenture  Trustee and Public Service
Company of New Mexico, a New Mexico  corporation  (PNM).  All capitalized  terms
used herein and not otherwise  defined  herein shall have the meanings set forth
in Appendix A to the  Participation  Agreement.  This opinion is being delivered
pursuant to Section 11(a)(25) of the Participation Agreement.

                As such counsel we have examined originals or copies,  certified
or  otherwise  identified  to  our  satisfaction,  of  such  corporate  records,
agreements and other instruments, certificates, orders, opinions, correspondence
with public officials,  certificates of officers and representatives of PNM, and
other  documents,  as we have deemed  necessary or advisable for the purposes of
rendering the opinions set forth herein.

                Based on the  foregoing,  we are of the opinion  that :under New
Mexico Applicable Law now in effect:


6091.BURNHAM.1106.08:l





                (1) Each Transaction Document to which PNM is a party,  assuming
        the due  authorization,  execution  and  delivery  thereof by each party
        thereto,  constitutes  the legal,  valid and binding  obligation of PNM,
        enforceable against PNM in accordance with its terms

                (2) Neither the execution, delivery or performance by PNM of any
        Transaction Document to which it is a party, nor the consummation by PNM
        of the transactions contemplated thereby, nor the compliance by PNM with
        the  provision  thereof,  conflicts  with or  results in a breach of any
        Applicable  Law of any  state,  county,  municipal,  regional  or  other
        governmental authority, agency, board, body, instrumentality or court of
        New Mexico ("New Mexico Governmental Authority").

                (3)  No   Governmental   Action  of  or  with  any  New   Mexico
        Governmental  Authority is required in  connection  with the  execution,
        delivery or  performance  by PNM of, or the  consummation  by PNM of the
        transaction  contemplated by, any Transaction Document to which PNM is a
        party,  except the New Mexico  Order,  which has been duly issued by the
        NMPSC, and such other New Mexico  Governmental  Actions (i) as have been
        duly obtained, given or accomplished,  and (ii) as may be required to be
        obtained,  given or accomplished from time to time after the date hereof
        in connection with the maintenance, use, possession or operation of Unit
        2 or otherwise  with respect to Unit 2 and PNM's  involvement  therewith
        and which are, for PVNGS,  routine in nature and which we have no reason
        to believe will not be timely obtained.

                (4)  Assuming  that  all  filings  required  to be made in other
        jurisdictions  have  been  duly  made,  upon  (a) the  filing  of  UCC-l
        financing  statements in appropriate  form relating to the Indenture and
        the Collateral Trust Indenture with the Secretary of State of New Mexico
        and the County Clerk of Bernalillo  County, New Mexico and the filing of
        the Indenture and the Collateral  Trust  Indenture with the Secretary of
        State of New Mexico  pursuant to the New Mexico Public  Utility Act, (b)
        the delivery of the  Original of the  Facility  Lease to, and so long as
        the same is retained by, the Indenture Trustee,  and (c) the delivery of
        the Pledge Lessor Notes (as defined in the Collateral  Trust  Indenture)

        to,  and so long as the same  are  retained  by,  the  Collateral  Trust
        Trustee,  the  Indenture  Trustee  will have a  perfected  UCC  security
        interest in the Lease  Indenture  Estate  pursuant to, and to the extent
        provided in, the Indenture, and the Collateral Trust Trustee will have a
        perfected UCC security  interest in the Pledged  Property (as defined in
        the Collateral Trust Indenture), pursuant to, and to the extent provided
        in, the Collateral  Trust  Indenture,  and no filing or recording of any
        document  (except those  enumerated above and the filing of continuation
        statements  in  appropriate  form with  respect  to the UCC-l  financing
        statements  referred  to above at the  time and in the  matter  provided
        under the laws of New Mexico) will be necessary or appropriate under the
        laws of New Mexico to  establish,  preserve,  protect  and  perfect  the
        security interests referred to above.

                 (5) So long as the Facility Lease is in effect, and in reliance
        upon  the New  Mexico  Order,  neither  the  Owner  Trustee,  the  Owner
        Participant,  nor the Indenture  Trustee,  will, by reason either of its
        entering  into  any  Transaction  Document  or  its  performance  of any
        transaction  contemplated  thereby,  be  subject  to  regulation  as  an
        "electric  utility," a "public  utility," or a "public  utility  holding
        company" by the NMPSC or any other New Mexico Governmental Authority.

                (6)  Neither  the Owner  Trustee  nor the  Indenture  Trustee is
        required  to qualify to do  business  in New Mexico in order to serve in
        such capacity.

                (7) No New Mexico Tax will be imposed  upon  payments of Rent by
        PNM to the Owner Trustee under the Facility Lease or in connection  with
        the transfer of the Undivided  Interest or the Real Property Interest by
        PNM to the Owner Trustee.

                The opinions  expressed  herein are subject in each> case (a) as
to enforceability,  to bankruptcy,  insolvency,  reorganization,  moratorium and
other  similar laws  heretofore  or hereafter  enacted  affecting  creditors' or
lessors' rights generally, general principles of equity, and the availability of
specific performance and other equitable remedies, (b) to the qualification that


                                       -3-
6091.BURNHAM.1106.08:l




any provision in the  Transaction  Documents which purports to permit any Person
to make  determinations,  take actions or require  payments under  indemnity and
similar  provisions may be subject to requirements  that such  determinations be
made, such actions be taken and such payments required on a reasonable basis and
in good  faith,  (c) to  possible  limitations  upon  the  exercise  of  certain
indemnity,  remedial  or  procedural  provisions  contained  in the  Transaction
Documents, which limitations do not in our opinion make such indemnity, remedial
or  procedural  provisions,  taken  as a  whole,  inadequate  for the  practical
realization of the benefits provided by the Transaction Documents, (d) as to the
perfection of UCC security interests in proceeds, to the qualification that such
perfection  is limited to the degree set forth in Section  9-306 of the UCC, and
(e)  as  to  the  perfection  of  UCC  security   interests  in  money,  to  the
qualification  that such perfection is limited to money in the possession of the
secured party.

                For  purposes  of this  opinion we have  assumed  that the Owner
Participant and the Lessor will exercise their rights, and that PNM will perform
its  obligations,  under  Section  13(c) of the  Facility  Lease  if it  becomes
necessary to do so to remain in compliance  with the New Mexico  Order.  We have
further  assumed  that no Lease  Transaction  (as  that  term is used in the New
Mexico Order) entered into by PNM subsequent to the date hereof will result in a
violation of the New Mexico Order.

                We do not purport to be experts in the laws of any jurisdictions
other than New  Mexico and the United  States.  The  opinions  expressed  herein
relate only to the existing  laws of New Mexico,  and we express no opinion with
respect  to the laws of the  United  States or any  jurisdiction  other than New
Mexico.  Our  opinions  do not cover any  matter  relating  to the "blue sky" or
securities laws of New Mexico or any other jurisdiction.


                                    Yours very truly,

                                    RODEY, DICKASON, SLOAN, AKIN & ROBS, P.A.

        indemnified" (as each such term is defined in the Price-Anderson Act) is

        Nuclear  Incident,  (ii) the aggregate  liability  for a single  Nuclear
        Incident  of  "persons  indemnified"  (as such  term is  defined  in the
        Price-Anderson   Act)  exceeds  the  amount  of   financial   protection
        established by the NRC as a condition to the License,  unless the change

6091.BURNHAM.1106.55:l




        is such that neither the Owner Trustee nor the Owner  Participant may be
        exposed, either during or subsequent to the Lease Term, to any increased
        real or potential liability in respect of a Nuclear Incident,  (iii) the
        amount of financial  protection  required,  including but not limited to
        the  limitation  on the amount of deferred  premiums for such  financial
        protection,  is  increased,  unless the change is such that  neither the
        Owner Trustee nor the Owner Participant may be exposed, either during or
        subsequent  to the  Lease  Term,  to any  increased  real  or  potential
        liability  in respect of a Nuclear  Incident,  or (iv)  either the Owner
        Trustee or the Owner Participant may be exposed to any other increase in
        its real or potential liability in respect of a Nuclear Incident, either
        during or subsequent to the Lease Term, it being understood for purposes
        of this  definition  that the  requirement  or existence  of  insurance,
        retrospective premiums,  indemnities (whether by the Lessee or any other

        other act of Congress or any other Governmental Authority, (y) the terms
        of such  financial  protection are otherwise  satisfactory  to the Owner
        Trustee and the Owner  Participant,  and (z) the Owner  Trustee or Owner
        Participant may not otherwise be exposed, either during or subsequent to
        the Lease Term, to any increased real or potential  liability in respect
        of a Nuclear  Incident;  provided,  however,  that such change shall not
        constitute  a  "Deemed  Loss  Event"  if such  change  shall  include  a
        provision  drafted  in a manner  reasonably  satisfactory  to the  Owner
        Participant  which exempts the Owner  Trustee and the Owner  Participant
        from all real and potential  liability in respect of a Nuclear  Incident
        so long as  neither  the Owner  Trustee or the Owner  Participant  is in
        actual  possession  and  control  of Unit 2 or the  Undivided  Interest,
        unless (in the opinion of independent  counsel to the Owner Participant)
        a court  could  reasonably  hold  that the  statute  incorporating  such
        provision is unconstitutional;

        or obligation imposed as of the date hereof on licensees of the NRC;

                 (4) Illegality.  If there shall be any change in Applicable Law

                (5)  Limitation  on  Exercise  of  Rights.  My change in, or new
        interpretation  by Governmental  Authority  having  jurisdiction of, the
        License  and the  License  Amendment  (each as in effect on the  Closing
        Date)  constituting  an assertion to the effect that the exercise by the
        Owner Trustee or the Owner Participant of any right (irrespective of the
        event giving rise to such right) under any  Transaction  Document  would
        constitute impermissible control over Unit 2 or the licensees of Unit 2,

        with the second sentence of Section 184 of the Atomic Energy Act and the
        NRC's regulations  thereunder  (including,  without  limitation,  10 CFR
        Section 50.81, as now and hereafter in effect);

        revocation,  suspension, amendment or interpretation by any Governmental
        Authority   of  the  License,   the  License   Amendment  or  any  other
        Governmental  Action or  change  in  Applicable  Law,  either  the Owner
        Trustee or the Owner  Participant shall be required to become a licensee
        of the NRC prior to the Lease Termination Date;

                (7)  Suspension or  Termination  of Insurance.  If any policy of
        liability  insurance  with  respect  to Unit 2  shall  be  5uupended  or
        terminated,   or  the  coverage  thereunder  reduced,   for  any  reason

        potential  liability in respect of a Nuclear Incident and such policy of
        insurance  shall  not be  immediately  replaced  by  insurance  or other
        financial  protection  satisfactory to the Owner  Participant  effective
        immediately upon such suspension,  termination,  reduction, amendment or
        supplementation   which,   in  the  reasonable   opinion  of  the  Owner
        Participant,  is at least as protective of it (in all respects deemed by
        it to be material) as the policy of insurance so terminated,  suspended,
        reduced,  amended or supplemented,  unless the aggregate liability for a
        Nuclear  Incident of "persons  indemnified"  (as such term is defined in
        the Atomic Energy Act of 1954, as amended) is reduced by an amount equal
        to the amount of liability insurance so terminated,  suspended, reduced,
        amended or  supplemented  and,  in the  reasonable  opinion of the Owner
        Participant,   it  may  not  otherwise  be  exposed,  either  during  or
        subsequent  to the  Lease  Term,  to any  increased  real  or  potential
