        contesting  such  determination  and  the  effects  thereof,  (iv)  such
        determination  and the effects  thereof shall be  effectively  stayed or
        withdrawn  during such contest (and shall not be subject to  retroactive
        application at the conclusion of such contest) in a manner  satisfactory
        to  the  Owner  Trustee  and  the  Owner  Participant,   and  the  Owner
        Participant  shall have determined  that the Owner  Trustee's  continued
        ownership  of the  Undivided  Interest  and the Real  Property  Interest
        during the pendency of such  contest or such contest will not  adversely
        affect its or its  Affiliates'  business,  and (V) the Lessee shall have
        indemnified  the Owner  Trustee  and the Owner  Participant  in a manner
        satisfactory  to each such Person for any liability or loss which either

                (2)  Price-Anderson  Act Change.  If there shall be, at any time
        during the Lease Term, any change in the Price-Anderson  Act, the Atomic
        Energy Act or the  regulations of the NRC, or any other  Applicable Law,
        in each case as in effect on the Closing Date, as a result of which,  in
        the opinion of independent  counsel for the Owner  Participant,  (i) the
        aggregate   liability  for  a  single   Nuclear   Incident  of  "persons
        indemnified" (as each such term is defined in the Price-Anderson Act) 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,  (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
        is such that neither the Owner Trustee nor


                                      -11-

6O91.BURNHAM.1106.55:1





        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  person) or other forms of financial  protection
        (similar or dissimilar to the  foregoing)  shall not be deemed to reduce
        or eliminate any exposure of the Owner Trustee or the Owner  Participant
        to real or potential  liability in respect of a Nuclear  Incident except
        to the extent (x) such  financial  protection  is provided by the United
        States Government under Congressional  action which does not require any
        further appropriation or 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;

                 (3) Liability for Termination Obligation. If there shall be any
        change in  Applicable  Law as a result of which the Owner  Trustee shall
        become liable in its individual capacity, or the Owner Participant shall
        become  liable  in  any  capacity,  in  respect  of any  portion  of the
        Termination Obligation (as defined in the ANPP Participation  Agreement)
        or Decommissioning  Costs or, during the Lease Term, any other liability
        or obligation imposed as of the date hereof on licensees of the NRC;

                 (4) Illegality.  If there shall be any change in Applicable Law
        or  any  Governmental  Action  the  effect  of  which  is  to  make  the
        transactions  contemplated  by the Transaction  Documents  unauthorized,
        illegal or otherwise contrary to Applicable Law;

                (5)  Limitation  on  Exercise  of Rights.  Any 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 Transact ion Document  would
        constitute impermissible control over Unit 2 or the licensees of Unit 2,
        other than an assertion that affects such rights in a manner  consistent
        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);

                (6) Early  Licensee  Status.  If as a result of any  expiration,
        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  suspended  or
        terminated,   or  the  coverage  thereunder  reduced,   for  any  reason
        whatsoever  or shall be amended  or  supplemented,  in either  case in a



                                      -13-

609l.BURNHAM.1106.55:1




        manner  which may  expose the Owner  Trustee  or the Owner  Participant,
        either during or subsequent to the Lease Term, to any increased  real or
        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
        liability  in respect of a Nuclear  Incident  as a  consequence  of such
        suspension, termination, reduction, amendment or supplementation.

                Default shall mean an event or condition which,  with the giving
