group).



(g) Tax Indemnity Claims.
Buyer shall notify Seller within thirty (30) days of receipt of written notice of any pending or threatened Tax examination, audit or other administrative or judicial proceeding relating to any member of the Company Group that could reasonably be

Buyer fails to provide such notice to

than the Company), pay over to the Seller any such refund or the amount of any such benefit within five (5) Business Days of the earlier of 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 permit Seller to control (at Sellers expense) the prosecution of any such refund claimed and shall

Energy in its legal name and, within such ninety (90) day period, to make all required filings with Governmental Authorities to effect such amendments.

condemnation proceeds received or payable in connection with the Taking or Takings shall be excluded from the calculation of Company Working Capital at Closing;



(b) Upon the occurrence of (i) any one or more Events of Loss, as a result of which the aggregate costs to
restore, repair or replace, less any insurance proceeds received or payable to the Company in connection with such Event or Events of Loss (provided that any insurance proceeds received or payable in connection with the Event or Events of Loss are
used to restore, repair or replace such Event or Events of Loss) are reasonably estimated to be greater than $10,000,000, and/or (ii) any one or more Takings, as a result of which the aggregate condemnation proceeds are reasonably estimated to be
greater than $10,000,000 (a Major Loss), Seller shall have, in the case of a Major Loss relating to one or more Events of Loss, the option, exercised by notice to the Buyer, to cause the Company to restore, repair or replace the affected
Assets. If the Seller elects not to cause the Company to restore, repair or replace the Assets affected by a Major Loss, or such Major Loss is the result of one or more Takings, the provisions of Section 5.19(c) will apply;



(c) In the event that the Seller elects not to cause the
Company to restore, repair or replace a Major Loss, or in the event that the Seller, having elected to cause the Company to repair, replace or restore the Major Loss, fails to cause the Company to complete such repair, replacement or restoration
prior to the Closing Date, or in the event that a Major

Loss is the result of one or more Takings, then the Parties shall, within thirty (30) days following the Sellers election not to cause the Company to
restore, repair or replace, failure to complete, or the occurrence of such Takings, as the case may be, negotiate in good faith an equitable adjustment in the Purchase Price to reflect the impact of the Major Loss, as mitigated by any repair,
replacement or restoration work actually completed by the Company, on the Assets, and proceed to the Closing at a Purchase Price so adjusted. To assist the Buyer in its evaluation of any and all Events of Loss, the Seller shall provide the Buyer
such access to the Assets and such information as the Buyer may reasonably request in connection therewith; and



(d) In the event that the Parties fail to reach agreement on an equitable adjustment of the Purchase Price within the thirty (30) days
provided in Section 5.19(c), then the Buyer shall have the right to elect, exercisable by notice to the Seller within fifteen (15) days immediately following the expiration of the thirty (30) day period, to (i) proceed with the consummation of the
transaction at the Closing, with a reduction in the Purchase Price, consistent with the Sellers last offer of equitable adjustment thereto as contemplated by the penultimate sentence of Section 5.19(c) communicated to the Buyer, in which event
the Seller shall assign over or deliver to the Buyer at the Closing all condemnation proceeds or insurance proceeds that the Seller receives, or to which the Seller become entitled by virtue of the Event of Loss or Taking with respect to the Assets,
less any costs and expenses reasonably incurred by the Seller in connection with such Events of Loss or Taking or in obtaining such, condemnation proceeds or insurance proceeds, and less the reduction in the Purchase Price made pursuant to this
clause (i), or (ii) submit the matter to dispute resolution pursuant to Section 9.16 to determine the adjustment, if any, in the Purchase Price, which determination shall be binding on all Parties. If the Buyer fails to make the election within the
fifteen (15) day period described in the preceding sentence, the Buyer will be deemed to have made the election to proceed with the Closing under clause (i) hereof.



(e) For the avoidance of doubt, any Event of Loss which has been repaired, replaced or restored by Seller
pursuant to Section 5.19(b) or any Taking or Event of Loss which has been the subject of a purchase price reduction pursuant to Section 5.19(c) or 5.19(d) shall be disregarded for purposes of determining whether Seller has breached any
representation or warranty hereunder, including for purposes of Section 6.2(a) and Section 7.1(i).

Group) and their respective directors, officers, partners and employees (each such Person, a Buyer Indemnified Party and, collectively, the Buyer Indemnified Parties), from and against any and all Losses actually incurred by
any Buyer Indemnified Party (i) for any breach of the representations and warranties contained in Article 3 or in any certificate delivered by Seller at the Closing with respect to such representations and warranties, (ii) for any breach of the
covenants or obligations of Seller under this Agreement, (iii) for any Seller Ownership Period Environmental Liability, or (iv) for any Pre-Closing ERISA Liability.



SECTION 7.2 Indemnification by Buyer. From and after the Closing, subject to the other terms and
limitations set forth in this Agreement, Buyer shall indemnify, defend, reimburse and hold harmless Seller, its Affiliates and their respective directors, officers, partners and



55



---

employees (each such Person, a Seller Indemnified Party and, collectively, the Seller Indemnified Parties), from and against any and
all Losses actually incurred by any Seller Indemnified Party (i) for any breach of Buyers representations or warranties made in this Agreement or in any certificate delivered by Buyer at the Closing with respect to such representations and
warranties, or (ii) for any breach of the covenants or obligations of Buyer under this Agreement.



SECTION 7.3Limitations on Indemnity.



(a) Except for the specific indemnity provided in Section 7.7 of this Agreement, anything in this Agreement
to the contrary notwithstanding, in no event shall Seller ever be required to indemnify any Buyer Indemnified Party for Losses pursuant to Section 7.1 or any of the other provisions of this Agreement, including Section 5.10 (or to pay any other
amount in connection with or with respect to this Agreement or the transactions contemplated by this Agreement) (i) until the aggregate amount of all such Losses shall have exceeded $5 million (the Deductible), whereupon only Losses in
excess of the Deductible shall be subject to indemnification hereunder; provided, however,that any individual Loss of less than $100,000 that is otherwise subject to indemnification hereunder shall be disregarded in determining whether any
Buyer Indemnified Party has incurred Losses up to or exceeding the Deductible, or (ii) in an amount exceeding, in the aggregate, 75% of the Adjusted Purchase Price.



(b) Notwithstanding anything to the contrary contained in this Agreement, Seller and Buyer agree that the
recovery by any Indemnified Party of any damages suffered or incurred by such Indemnified Party as a result of any breach by another Party of any of its obligations under this Agreement shall be limited to the actual damages suffered or incurred by
an Indemnified Party as a result of the breach by the breaching Party of its obligations hereunder, and in no event shall the breaching Party be liable to an Indemnified Party for any indirect, consequential, special, exemplary or punitive damages
(including any damages on account of lost profits or opportunities or lost or delayed generation) suffered or incurred by an Indemnified Party as a result of the breach by the breaching Party of any of its obligations hereunder.



SECTION 7.4Indemnity Procedures.



(a) If a claim by a third party is made against a Seller
Indemnified Party or a Buyer Indemnified Party (any such person, an Indemnified Party) or an Indemnified Party shall otherwise learn of an assertion or of a potential claim, and if such Indemnified Party intends to seek indemnity with
respect thereto under this Article 7 (other than with respect to an indemnity arising out of the breach of any representation or warranty contained in Sections 3.16, 3.17 or 3.23, which shall be governed by Section 5.10(g)), such Indemnified Party
shall promptly furnish written notice of such claim (in reasonable detail and including the factual basis for such claim and, to the extent known, the amount thereof) to the Party against whom 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



56



---

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 Parry 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 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



57



---

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 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



58



---

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 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.

(b) by British Energy or Buyer if the Closing

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

breach, and such violation or breach has not been waived by British Energy;



(h) by Buyer or Seller if Exelon exercises its right of first refusal to acquire British Energys interests in the Company pursuant to Section 7.3 of the Limited Liability Company Agreement within the period of
time in which such right may be exercised as provided in Section 7.3 of the Limited Liability Company Agreement.

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)

consequences of such termination and is not a penalty.



(iii) Notwithstanding Section 8.3(d), in the event that the transaction which resulted in the termination of this Agreement pursuant to Section 8.1(h) is terminated within three (3) years from the date hereof, Seller and Buyer shall as soon
as practicable enter into a 90-day exclusivity agreement whereby the Buyer shall be given the opportunity, on an exclusive basis, to acquire the BEUSH Shares on terms to be agreed upon by the Parties. Such exclusivity agreement shall contain
customary rights and obligations and shall be negotiated in good faith by the Parties.



(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.
