under Section 7.1 as a result of the breach of any representation or warranty contained in Sections 3.16, 3.17 or 3.23 (Contested Taxes). If Buyer fails to provide such notice to Seller, Buyer shall not be entitled to indemnification for
such Contested Taxes if the failure shall preclude Seller from contesting the Tax. Seller shall, at its own expense, control the defense and settlement of such Tax contest. Buyer shall have the right to participate in the conduct of any Tax contest
relating to the Contested Taxes at its own expense, including through its own counsel and other professional experts and shall be entitled to control such Tax contest in the event that Seller fails to do so. Seller shall consult with Buyer prior to

unreasonably withheld; provided however, that Seller shall not settle any Tax contest without the

receipt or entitlement thereto. Buyer shall, if Seller so requests and at Sellers expense, cause the relevant entity to file for and obtain any refunds or equivalent amounts to which Seller is entitled under this Section 5.10(h). Buyer shall

indemnity is sought (such Party, in such capacity, the Indemnifying Party). Thereafter, the Indemnified Party will deliver to the Indemnifying Party, promptly after the Indemnified Partys receipt thereof, copies of all material
notices and documents (including court papers) received or transmitted by the Indemnified Party relating to such claim. The failure of the Indemnified Party to deliver prompt written notice of a claim shall not affect the indemnity obligations of
the Indemnifying Party hereunder, except to the extent the Indemnifying Party was actually disadvantaged by such delay in delivery of notice of such claim. The Indemnifying Party shall have thirty (30) days after receipt of such notice to provide
written notice to the Indemnified Party acknowledging unconditionally its obligations to indemnify the Indemnified Party with respect to such claim (an Acceptance Notice) and if it delivers an Acceptance Notice, to elect to undertake,
conduct and control (through counsel of its own choosing and at its own expense), the settlement or defense of such claim, and the Indemnified Party shall cooperate with it in connection therewith. If the Indemnifying Party does not assume the
conduct and control of such settlement and defense, it shall have the right to participate in the settlement or defense of such claim, and the Indemnified Party shall cooperate with it in connection therewith. If the Indemnifying Party elects to
undertake, conduct and control the settlement or defense of such claim, the Indemnifying Party shall permit the Indemnified Party to participate in such settlement or defense through counsel chosen by such Indemnified Party (but the fees and
expenses of such counsel shall be borne by such Indemnified Party). So long as the Indemnifying Party, at the Indemnifying Partys cost and



55



---

expense, (i) has undertaken the defense of, and assumed full responsibility for all indemnified liabilities with respect to, such claim, (ii) is reasonably
contesting such claim in good faith through appropriate proceedings, and (iii) has taken such action (including the posting of a bond, deposit or other security) as may be necessary to prevent any action to foreclose a lien against or attachment of
the property of the Indemnified Party for payment of such claim, the Indemnified Party shall not pay or settle any such claim; provided, however,that, the Indemnified Party shall have the right to pay or settle any such claim if it has
waived in writing any right to indemnity by the Indemnifying Party for such claim; and, provided, further,that, if within thirty (30) days after the receipt of the Indemnified Partys notice of a claim of indemnity under this Section
7.4(a), the Indemnifying Party does not notify the Indemnified Party that it elects (at the Indemnifying Partys cost and expense) to undertake the defense thereof and assume full responsibility for all indemnified liabilities with respect
thereto, or gives such notice and thereafter fails to contest such claim in good faith or to prevent action to foreclose a lien against or attachment of the Indemnified Partys property as contemplated above, the indemnified Party shall have
the right to contest, settle or compromise such claim and the Indemnified Party shall not thereby waive any right to indemnity for such claim under this Agreement.



(b) Any claim on account of Losses for which indemnification is provided under this Agreement which does not
involve a claim of a third party will be asserted by prompt written notice (setting forth in reasonable detail the facts or circumstances that allegedly give rise to such claim and, to the extent known, the amount thereof) given by the Indemnified
Party to the Indemnifying Party from whom such indemnification is sought. The failure or delay by any Indemnified Party to so notify the Indemnifying Party will not relieve the Indemnifying Party from any liability which it may have to such
Indemnified Party under this Agreement, except to the extent that the Indemnifying Party is actually disadvantaged by such delay in delivery of notice of such claim.



(c) In the event of payment in full by an Indemnifying Party to any Indemnified Party in connection with any
claim (an Indemnified Claim), such Indemnifying Party will be subrogated to and will stand in the place of such Indemnified Party as to any events or circumstances in respect of which such Indemnified Party may have any right or claim
relating to such Indemnified Claim against any claimant or plaintiff asserting such Indemnified Claim or against any other Person. Such Indemnified Party will cooperate with such Indemnifying Party in a reasonable manner, and at the cost and expense
of such Indemnifying Party, in prosecuting any subrogated right or claim.



SECTION 7.5Procedural Requirements for Environmental Claims by Buyer. The provisions of this Section 7.5 are in addition to, and not in limitation of, the procedures set forth in Section
7.4 (which shall be deemed superseded to the extent inconsistent with this Section 7.5). Buyer will provide Seller with prompt notice describing in reasonable detail any condition or claim in respect of which Losses arising out of a breach of the
representations and warranties in Section 3.20 or any Seller Ownership Period Environmental Liability are or may be incurred by any Buyer Indemnified Party; provided, however,that if such notice is not given within a sufficient period of
time or in sufficient detail to apprise Seller of the nature of any such condition or claim (in each instance taking into account the facts and circumstances with respect thereto), the costs and expenses incurred by such Buyer Indemnified Party in
connection with such condition or claim shall not constitute Losses to the extent that Sellers position is actually prejudiced as a result thereof. Seller will have the option to participate, at their own expense, in



56



---

the resolution of any such conditions or claims (and, in any event, Buyer will consult in good faith with Seller in respect of the resolution of any such
conditions or claims). Buyer will keep Seller apprised of the status of and any action by or on behalf of Buyer or any member of the Company Group or their respective Affiliates with respect to all such conditions or claims. If Seller is not given,
within a sufficient period of time or in sufficient detail, information necessary to reasonably apprise Seller of the status of and any action by or on behalf of Buyer, any member of the Company Group or their respective Affiliates with respect to
any such conditions or claims (in each instance taking into account the facts and circumstances with respect thereto), the costs and expenses incurred by Buyer or any member of the Company Group in connection with such condition or claim shall not
constitute Losses to the extent that Sellers position is actually prejudiced as a result thereof.



SECTION 7.6Survival and Time Limitation. The terms and provisions of this Agreement shall survive the Closing of the
transactions contemplated hereunder. Notwithstanding the foregoing, after Closing, any claim by any Buyer Indemnified Party that Seller is liable to such Buyer Indemnified Party under the terms of this Agreement for breach of any representations and
warranties of Seller must be given to Seller on or prior to the date that is twelve (12) months after the Closing Date, except for (i) any claims for breach of the representations and warranties of Seller in Sections 3.1, 3.2, 3.3, 3.10, 3.11, 3.12,
3.16, 3.17 and 3.23, and any claims made by Buyer pursuant to Section 5.10, which must be given to Seller (or not at all) on or prior to the date that is ninety (90) days after the expiration of all applicable statutes of limitations with respect to
the matters covered thereby, (ii) any claim for breach of the representations and warranties of Seller in Sections 3.7, 3.8, 3.9 and 3.36, which shall survive indefinitely, (iii) except as described in clause (iv) of this Section 7.6, any claim for
breach of the representations and warranties of Seller in Section 3.20, which must be given to Seller on or prior to the date that is twenty-four (24) months after the Closing Date, (iv) any claim for breach of Section 3.20 relating to the matters
described in Section 7.7 hereof, which shall survive until the later of the complete and conclusive resolution of any such matters with any applicable Governmental Authority or the payment in full of any amounts owed to each Buyer Indemnified Party
under Section 7.7, and (v) any claim for breach of Section 3.37, which shall survive for the initial license term of each respective Facility. Notwithstanding the initial sentence of this Section 7.6, after Closing, any claim by any Seller
Indemnified Party that Buyer is liable to such Seller Indemnified Party for a breach of any representations and warranties of Buyer must be given to Buyer on or prior to the date that is twelve (12) months after the Closing Date. All covenants and
other agreements of Seller and Buyer contained in this Agreement that by their terms are to be performed after the Closing shall survive until the expiration of all applicable statutes of limitations with respect to the matters covered thereby.



SECTION 7.7Specific Indemnity by
Seller. Notwithstanding the foregoing, from and after the Closing, Seller shall indemnify, defend, reimburse and hold harmless each Buyer Indemnified Party from and against any and all Losses actually incurred by any Buyer Indemnified
Party that were incurred by such Buyer Indemnified Party as a result of the Fish Kill described in Schedule 3.20 hereof (including without limitation any and all Losses actually incurred in connection with the allegations set forth in
Schwartz v. AmerGen Energy Company, Exelon Generation Company, British Energy Company et al.; Superior Court of New Jersey, Docket L-2075-03 as filed on July 25, 2003, and any subsequent amendments to the allegations



57



---

related to the Fish Kill, as described in Schedule 3.20 hereof). In connection with making an Indemnified Claim, the Parties shall follow the
Indemnification Procedures described in Sections 7.4 and 7.5 above.



SECTION 7.8Further Indemnity Limitations.The amount of any indemnifiable Loss shall be reduced (i) to the extent any Indemnified Party actually receives any insurance proceeds with respect to such
Loss, (ii) to take into account any net Tax benefit arising from the recognition of the Loss, (iii) to take into account any payment actually received by an Indemnified Party from a third party with respect to such Loss, and (iv) to the extent of
any Loss that is attributable to a determination that the initial Tax Basis of the assets of the Company should not be increased by the amount of the nonqualified decommissioning liability.



SECTION 7.9Sole and Exclusive Remedy.From and after the Closing, except as provided in Section 5.10 of this Agreement for any claim in respect of Taxes, the indemnification provisions of this Article 7 shall be the sole and exclusive post-Closing remedy of each Party
(including the Seller Indemnified Parties and the Buyer Indemnified Parties) (i) for any breach of any Partys representations, warranties, covenants or agreements contained in this Agreement, or (ii) otherwise with respect to this Agreement or
the transactions contemplated hereby. In furtherance of the foregoing, each Party hereby waives, to the fullest extent permitted under applicable Law, any and all other rights, claims and causes of action it or any of its Affiliates may have against
another Party hereunder with respect thereto.



ARTICLE 8



Termination



SECTION 8.1 Termination. This Agreement may be
terminated at any time prior to the Closing:



(a) by mutual written agreement of British Energy and Buyer;



(b) by British Energy or Buyer if the Closing shall not have been consummated on or before the day that is six (6) months after the date hereof, unless the reason that the Closing has not occurred shall be the failure
of the Party seeking to terminate this Agreement to fulfill its obligations hereunder; provided, however, (i) that if the reason the Closing has not occurred is because Buyer Regulatory Approvals or British Energy Regulatory Approvals have not been
obtained and Commercially Reasonable Efforts are being undertaken to obtain such regulatory approvals by the Party responsible for obtaining such regulatory approvals, the reference to the day that is six (6) months after the date hereof in
this Section 8.1(b) shall be extended for an additional six (6) months and neither British Energy nor Buyer may terminate this Agreement during such extended period so long as such Commercially Reasonable Efforts continue, or (ii) that if the reason
the Closing has not occurred is because FPL Energy Nuclear Mid-Atlantic, LLC or its Affiliates (collectively FPL) is attempting to prevent the transfer of the Sellers indirect interest in the Company and Seller has timely commenced
arbitration proceedings or other legal action with FPL regarding FPLs action or inaction with respect to such transfer, the reference to the day that is six (6) months after the date hereof in this Section 8.1(b) shall be extended for an
additional six (6) months and neither British Energy nor Buyer may terminate this Agreement during such extended period;



58



---

(c) by British Energy or Buyer if consummation of the transactions contemplated hereby
would violate any nonappealable final order, decree or judgment of any court or governmental body having competent jurisdiction;



(d) by Buyer if any Buyer Regulatory Approvals shall have been denied (and a petition for rehearing, a petition for review or refiling of
an application initially denied without prejudice shall also have been denied) or shall have been granted subject to terms and conditions that would likely have a Material Adverse Effect, and all appeals of any such actions shall have been taken and
been unsuccessful;



(e) by British Energy if
any British Energy Regulatory Approvals shall have been denied (and a petition for rehearing, a petition for review or refiling of an application initially denied without prejudice shall also have been denied) or shall have been granted subject to
terms and conditions that would likely have a Material Adverse Effect, and all appeals of any such actions shall have been taken and been unsuccessful;



(f) by Buyer if there has been a material violation or breach by British Energy of any covenant representation or warranty contained in
this Agreement and such violation or breach is not cured by the earlier of the Closing Date or the date thirty (30) days after receipt by British Energy of written notice specifying particularly such violation or breach, and such violation or breach
has not been waived by Buyer;



(g) by British
Energy if there has been a material violation or breach by Buyer of any covenant, representation or warranty contained in this Agreement and such violation or breach is not cured by the earlier of the Closing Date or the date thirty (30) days after
receipt by Buyer of written notice specifying particularly such violation or breach, and such violation or breach has not been waived by British Energy;



The Party desiring to terminate this Agreement shall give notice of such termination to the other Party in the manner set forth in Section 8.2.



SECTION 8.2 Effect of
Termination.In the event of termination of this Agreement by Seller or Buyer pursuant to Section 8.1, written notice thereof shall promptly be given by the terminating Party to the other Parties, and this Agreement shall thereupon
terminate provided, however,the termination of this Agreement shall not release any party from liability for any breach of any representation, warranty or covenant contained herein prior to the date of termination. Following any such
termination, Buyer and Seller will continue to be bound by the obligations set forth in Sections 5.8 and 5.9 and Article 7. If this Agreement is terminated as provided herein, all filings, applications and other submissions made to any Governmental
Authority shall, to the extent practicable, be withdrawn from the Governmental Authority to which they were made.



SECTION 8.3 Remedies.



(a) Sellers Remedies. (i) Notwithstanding anything herein to the contrary, upon the failure by Buyer to fulfill any
undertaking or commitment provided for herein on the



59



---

part of Buyer that is required to be fulfilled on or prior to the Closing Date, Seller, at its sole option, may enforce specific performance of this
Agreement or pursue any rights or remedies available at law or in equity.



(b) Sellers Remedy for Termination Pursuant to Section 8.1(b), 8.1(c), 8.1(d) or 8.1(e). In the event that (i) this Agreement is terminated pursuant to any of Section 8.1(b) through 8.1(e), (ii) such
termination resulted from a failure to obtain applicable regulatory approvals, and (iii) such failure is attributable to the announcement or consummation after the date hereof of any transaction pursuant to which Buyer or any of its Affiliates would
acquire any electric generation facilities or uncommitted electric generating capacity, Buyer shall pay to Seller, no later than five (5) days after any such termination, by wire transfer of immediately available funds to an account designated in
writing by Seller, an amount equal to $8,295,000.



(c) Buyers Remedies. Except as set forth in Section 8.3(d) hereof, notwithstanding anything herein provided to the contrary, upon failure of Seller to fulfill any undertaking or commitment provided for herein on the part of
Seller that is required to be fulfilled on or prior to the Closing Date, Buyer, at its sole option, may enforce specific performance of this Agreement or pursue any rights or remedies available at law or in equity.



(d) Buyers Remedy for Termination Pursuant to
Section 8.1(b). In the event that this Agreement is terminated by Buyer or Seller pursuant to Section 8.1(b) and the Closing shall not have been consummated as a result of FPLs material interference with the transactions contemplated
hereby, Buyers sole and exclusive remedy for such termination shall be a termination payment in the amount of $8,295,000 (the Break Up Fee), payable by Seller to Buyer by wire transfer no later than five (5) days after the
consummation of any sale of the BEUSH Shares which directly or indirectly transfers the Company Groups ownership interest in the Company to FPL or an Affiliate thereof; provided that,in the event that, following such a termination of
this Agreement, Seller has not consummated such a sale of its direct or indirect ownership interests in the Company within one (1) year of the date of this Agreement, Seller shall make a payment to Buyer, within three (3) Business Days after the
first anniversary of the date hereof, in the amount of $1,000,000, such amount to be deducted from any payment of the Break Up Fee upon consummation of such a sale within three (3) years from the date of this Agreement. In the event such a sale of
Sellers direct or indirect ownership interests in the Company is not consummated within three (3) years from the date of this Agreement, Seller shall have no further liability to Buyer for termination pursuant to Section 8.1(b). The Parties
agree that Buyers actual damages as a result of such termination would be extremely difficult to calculate, and that such payment constitutes liquidated damages for the consequences of such termination and is not a penalty.



(e) Election of Remedies. (i) Except as set forth in
Section 8.3(d) hereof, if any Party elects to pursue singularly any right or remedy available to it under this Section 8.3, then such Party may at any time thereafter cease pursuing that right or remedy and elect to pursue any other right or remedy
available to it under this Section 8.3. All rights and remedies hereunder (except those set forth in Section 8.3(d)) shall be cumulative. Except as otherwise provided by Applicable Law, no delay or forbearance by a Party in the exercise or
enforcement of any right or remedy hereunder shall be deemed a waiver by such party of its right hereunder to exercise or enforce such right or remedy.
