(b)Separation Taxes

(i)In the event that Separation Taxes become due and payable to a Taxing Authority pursuant to a Final Determination, then, notwithstanding anything to the contrary in this Agreement:

(A)if such Separation Taxes are attributable to a Tainting Act of any member of the Exelon Group or to a transaction after the Distribution Date involving the stock of any member of the Exelon Group (an “Exelon Tainting Act”), and are not also attributable to a Tainting Act of any member of the Constellation Group or to a transaction after the Distribution Date involving the stock of any member of the Constellation Group (a “Constellation Tainting Act”), then Exelon shall be responsible for such Separation Taxes;

(B)if such Separation Taxes are attributable to a Constellation Tainting Act, and are not also attributable to an Exelon Tainting Act, then Constellation shall be responsible for such Separation Taxes;

(C)if such Separation Taxes are attributable to both an Exelon Tainting Act and a Constellation Tainting Act, then such Separation Taxes shall be equitably apportioned between the Parties based upon their relative fault; provided that in the event the Parties cannot agree regarding their relative fault, the matter shall be resolved in accordance with Article VII; and

(a)If pursuant to a Determination an Adjustment (i) increases the amount of liability for any Taxes for which a member of the Exelon Group is responsible hereunder and a Tax Benefit is made allowable to a member of the Constellation Group for any Post-Distribution Period, which Tax Benefit would not have arisen or been allowable but for such Adjustment, and which Tax Benefit reduces Taxes in respect of a Tax period for which any member of the Constellation Group is liable (and for which no member of the Exelon Group is liable) or (ii) increases the amount of liability for any Taxes for which a member of the Constellation Group is responsible hereunder and a Tax Benefit is made allowable to any member of the Exelon Group for any Pre-Distribution Period, which Tax Benefit would not have arisen or been allowable but for such Adjustment, and which Tax Benefit reduces Taxes in respect of a Tax period for which a member of the Exelon Group is liable (and for which no member of the Constellation Group is liable), then Constellation or Exelon, as the case may be, shall make a payment to either Exelon or Constellation, as appropriate, within forty-five (45) days of the date that such paying Party (or any member of the Exelon Group or Constellation Group, as applicable) actually receives such Tax Benefit (determined by comparing its Tax liability with and without the Tax consequences of the Adjustment), which payment shall not exceed the increase in the amount of liability for any Taxes resulting from such Adjustment, for which a member of the Exelon Group or Constellation Group, is responsible hereunder.

2.04 Allocation of Certain Income Taxes and Income Tax Items.

(a)If Exelon, Constellation, or any of their respective Affiliates is permitted but not required under applicable federal, state, local or foreign Tax Laws to treat the Distribution Date as the last day of a taxable period, then, in accordance with Section 2.02(a)(iii), the Parties shall (or shall cause its Affiliates to) treat such day as the last day of a taxable period under such applicable Tax Law, and shall file or cause to be filed any elections necessary or appropriate to such treatment; provided that this Section 2.04(a) shall not be construed to require Exelon or Constellation to change its taxable year.

(b)Tax Attributes arising in a Pre-Distribution Period shall be allocated to the Exelon Group and Constellation Group in accordance with principles set forth in the Prior Tax Sharing Agreement, unless otherwise required by the Code and Treasury Regulations (and any applicable state, local, and non-U.S. Laws). Exelon and Constellation shall jointly determine the allocation of such Tax Attributes arising in Pre-Distribution Periods as soon as reasonably practicable following the Distribution Date, and hereby agree to compute all Taxes for Post-Distribution Periods consistently with that determination unless otherwise required by a Determination.

 11

(c)The Parties agree that, in connection with the Distribution, Exelon’s current and accumulated earnings and profits will be allocated between Exelon and Constellation based on their relative fair market values at the time of the Distribution in accordance with Treasury Regulation § 1.312-10.

(a)For all Post-Distribution Periods, solely the Party (or its Subsidiary) that then employs or engages the relevant individual or, if such individual is not then employed or engaged by a Party, the Party (or its Subsidiary) that most recently employed or engaged such individual, at the time of the vesting, exercise, disqualifying disposition, payment or other relevant taxable event, as appropriate, in respect of the Equity Awards and all other nonqualified deferred compensation plans and Non-ERISA Benefit Arrangements described in Sections 3.3 and Article V the Employee Matters Agreement (“Other Compensatory Payments”), shall be entitled to claim any Income Tax deduction arising after the Distribution Date in respect of such Equity Awards and Other Compensatory Payments on its respective Tax Return.

(b)The Party (or its Subsidiary) that claims the deduction described in Section 2.05(a) shall be responsible for all applicable Taxes (including withholding and excise taxes) and shall satisfy, or shall cause to be satisfied, all applicable Tax reporting obligations in respect of the Equity Awards and Other Compensatory Payments that gives rise to the deduction. The Parties shall cooperate (and shall cause their Subsidiaries to cooperate) so as to permit the Party (or Subsidiary thereof) claiming such deduction described in Section 2.05(a) to discharge any applicable Tax withholding and Tax reporting obligations, including the appointment of the Party claiming the deduction (or its Subsidiary) as the withholding and reporting agent if that Party (or any of its Subsidiaries) is not otherwise required or permitted to withhold and report under applicable Law.

2.06 Tax Refunds and Certain Tax Attributes.

(a)Except as otherwise provided in this Article II, the benefit of any Tax credits, Tax Attributes, and any refund or credit of any overpayment of Taxes or estimated Tax liabilities (each, a “Refund”), including any corresponding benefit arising out of or related to any Tax liability that is the subject of this Agreement, will remain with the Party entitled to the benefit under applicable Tax Law. No payments shall be made between the Parties to account for such adjustment.

(b)Except as provided in Section 2.07, Exelon shall be entitled to all Refunds for Taxes for which Exelon is responsible pursuant to Article II, and Constellation shall be entitled to (i) all Refunds for Taxes for which Constellation is responsible pursuant to Article II and (ii) the amount of any actual reduction in the cash Tax liability of Exelon or its Affiliates following the Distribution Date to the extent attributable to the utilization of Constellation Tax Credit Carryforwards. A Party receiving a Refund or the benefit of a Constellation Tax Credit Carryforward to which the other Party is entitled pursuant to this Agreement shall (x) notify the other Party within thirty (30) days of the Receipt of such Refund (or the reduction in any Tax payment as a result of any Constellation Tax Credit Carryforward) and (y) pay the amount to which such other Party is entitled within forty-five (45) days after the receipt of the Refund or the utilization of such Constellation Tax Credit Carryforward. Each Party shall cooperate in good faith to secure any Refunds for Taxes to which the other Party may be entitled; provided, however, that Exelon may, in its reasonable discretion, determine not to seek a Refund on behalf of Constellation if obtaining such Refund would require any member of the Exelon Group to file an amended Tax Return.

 12

(c)In the event of an Adjustment relating to Taxes for which one Party is responsible pursuant to Article II which would have given rise to a Refund but for an offset against the Taxes for which the other Party is or may be responsible pursuant to Article II (the “Benefited Party”), then the Benefited Party shall pay to the other Party, within forty-five (45) days of the Determination of such Adjustment an amount equal to the lesser of (i) the amount of such hypothetical Refund or (ii) the amount of such reduction in the Taxes of the Benefited Party, in each case, plus interest at the Interest Rate on such amount for the period from the filing date of the Tax Return that would have given rise to such Refund to the payment date.

(d)Notwithstanding Section 2.06(a), to the extent that a Party applies or causes to be applied an overpayment of Taxes as a credit toward or a reduction in Taxes otherwise payable (or a Taxing Authority requires such application in lieu of a Refund) and such overpayment of Taxes, if received as a Refund, would have been payable by such Party to the other Party pursuant to this Section 2.06, such Party shall pay such amount to the other Party no later than the due date of the Tax Return for which such overpayment is applied to reduce Taxes otherwise payable.

(e)To the extent that the amount of any Refund or Constellation Tax Credit Carryforward under this Section 2.06 or Section 2.07(b)(i), as applicable, is later reduced by a Taxing Authority or in a Tax Proceeding, such reduction (together with any corresponding interest, penalties, or additions to Tax) shall be allocated to the Party to which such Refund or Constellation Tax Credit Carryforward was allocated pursuant to this Section 2.05 or Section 2.07(b)(i), as applicable, and an appropriate adjusting payment shall be made.

(i)Subject to Section 2.07(c) and (d), in the event that any member of the Constellation Group realizes any loss, credit, or other Tax Attribute in a Post-Distribution Period of such member, such member may elect to carry back such loss, credit, or other Tax Attribute to a Pre-Distribution Period or Straddle Period of Exelon. Exelon shall cooperate with Constellation and such member in seeking from the appropriate Taxing Authority any Refund that reasonably would result from such carryback (including by filing an amended Tax Return) at Constellation’s cost and expense; provided, however, that Exelon shall not be required to seek such Refund, and Constellation and such member shall not be permitted to seek or otherwise be entitled to such Refund, in each case to the extent that such Refund would reasonably be expected to materially adversely impact Exelon (including through an increase in Taxes or a loss or reduction of a Tax Attribute regardless of whether or when such Tax Attribute otherwise would have been used), without the prior written consent of Exelon, which consent shall not be unreasonably withheld or delayed. Subject to the foregoing, Constellation (or such member) shall be entitled to any Refund realized by any member of the Exelon Group or the Constellation Group resulting from such carryback.

 13

(ii)Subject to Section 2.07(c) and (d), in the event that any member of the Exelon Group realizes any loss, credit or other Tax Attribute in a Post-Distribution Period of such member, such member may elect to carry back such loss, credit or other Tax Attribute to a Pre-Distribution Period or Straddle Period of such member. Constellation shall cooperate with Exelon and such member in seeking from the appropriate Taxing Authority any Refund that reasonably would result from such carryback (including by filing an amended Tax Return) at Exelon’s cost and expense; provided, however, that Constellation shall not be required to seek such Refund and Exelon and such member shall not be permitted to seek or otherwise be entitled to such Refund, in each case to the extent that such Refund would reasonably be expected to materially adversely impact Constellation (including through an increase in Taxes or a loss or reduction of a Tax Attribute regardless of whether or when such Tax Attribute otherwise would have been used), without the prior written consent of Constellation, which consent shall not be unreasonably withheld or delayed. Subject to the foregoing, Exelon (or such member) shall be entitled to any Refund realized by any member of the Constellation Group or the Exelon Group resulting from such carryback.

(c)Except as otherwise provided by applicable Law, if any loss, credit or other Tax Attribute of the Exelon Business and the Constellation Business both would be eligible to be carried back or carried forward to the same Pre-Distribution Period (had such carryback been the only carryback to such taxable period), any Refund resulting therefrom shall be allocated between Exelon and Constellation proportionately based on the relative amounts of the Refunds to which the Exelon Business and the Constellation Business, respectively, would have been entitled had such carryback been the only carryback to such taxable period.

(d)To the extent the amount of any Refund under this Section 2.07 is later reduced by a Taxing Authority or a Tax Proceeding, such reduction (together with any corresponding interest, penalties, or additions to Tax) shall be allocated to the Party to which such Refund was allocated pursuant to this Section 2.07, and an appropriate adjusting payment shall be made.

2.08 Protective Section 336(e) Elections.

(a)Exelon and Constellation shall make a protective election with respect to Constellation under Section 336(e) of the Code (and any similar election under state or local Law) with respect to the Distribution in accordance with Treasury Regulations Section 1.336-2(h) and (j) (and any applicable provisions under state and local Law) and shall fully cooperate in the timely completion and/or filings of such elections and any related filings or procedures (including filing or amending any Tax Returns to implement an election that becomes effective). This Section 2.08(a) is intended to constitute a binding, written agreement to make an election under Section 336(e) of the Code with respect to the Distribution.

 14

(b)Notwithstanding anything to the contrary herein, in the event that the election contemplated in Section 2.08(a) is made and becomes effective, then the Parties shall share in any Tax Benefit derived as a result of such election in accordance with the Parties’ relative responsibility for such Taxes under this Article II, and payments shall be made between the Parties, if necessary.

(c)Exelon and Constellation shall cooperate in good faith in order to determine whether to make a protective election under Section 336(e) of the Code (and any similar election under state or local Law) with respect to any subsidiary of Constellation in accordance with Treasury Regulations Section 1.336-2(h) and (j) (and any applicable provisions under state and local Law).

4.03 Procedures Regarding Opinions.

(a)Constellation shall be permitted to take or allow the actions described in Section 4.02 (each, a “Restricted Action”) if, prior to taking or allowing any such Restricted Action, Constellation shall (1) have received written consent from Exelon, which consent may be withheld in the sole discretion of Exelon, (2) have received a favorable private letter ruling from the IRS that confirms that such Restricted Action will not, when considered together with any other relevant transactions, result in Separation Taxes (a “Post-Distribution Ruling”), in form and substance satisfactory to Exelon in its discretion, which discretion shall be reasonably exercised in good faith solely to ensure that the Restricted Action does not result in the imposition on either Party, or responsibility for payment by either Party, of Separation Taxes or (3) have received an Unqualified Tax Opinion that confirms that such Restricted Action will not result in Separation Taxes, when considered together with any other relevant transactions, in form and substance satisfactory to Exelon in its discretion, which discretion shall be reasonably exercised in good faith solely to ensure that the Restricted Action does not result in the imposition on either Party, or responsibility for payment by either Party, of Separation Taxes. Constellation shall provide a copy of the Post-Distribution Ruling or the Unqualified Tax Opinion described in this Section 4.03(a) to Exelon as soon as practicable prior to taking or failing to take any Restricted Action. Exelon’s evaluation and approval of such Post-Distribution Ruling or Unqualified Tax Opinion shall not be unreasonably withheld or delayed; provided, however, that Exelon’s evaluation of such Post-Distribution Ruling or Unqualified Tax Opinion may consider, among other factors, the appropriateness of any underlying assumptions, representations, and covenants made in connection with such Post-Distribution Ruling or Unqualified Tax Opinion. Constellation shall bear all costs and expenses of requesting and securing any such Post-Distribution Ruling or Unqualified Tax Opinion and shall reimburse Exelon for all reasonable out-of-pocket costs and expenses that Exelon may incur in seeking to obtain or evaluate any such Post-Distribution Ruling or Unqualified Tax Opinion.

(b)If Constellation notifies Exelon that it desires to take or permit a Restricted Action, Exelon shall reasonably cooperate with Constellation and use its commercially reasonable efforts to seek to obtain, as expeditiously as possible, a Post-Distribution Ruling or an Unqualified Tax Opinion for the purpose of permitting Constellation to take the Restricted Action unless Exelon shall have waived the requirement to obtain such Post-Distribution Ruling or Unqualified Tax Opinion. If such a Post-Distribution Ruling is to be sought, Exelon shall apply for such ruling and Exelon and Constellation shall jointly control the process of obtaining such ruling. In no event shall Exelon be required to file any ruling request under this Section 4.03 unless Constellation represents that (i) it has reviewed such ruling request, and (ii) all information and representations, if any, relating to any member of the Constellation Group, contained in such ruling request documents are (subject to any qualifications therein) true, correct, and complete. Constellation shall reimburse Exelon for all costs and expenses incurred by the Exelon Group in applying for and obtaining a Post-Distribution Ruling or an Unqualified Tax Opinion requested by Constellation within forty-five (45) days after receiving any invoice from Exelon therefor.

 20

(c)If Exelon requests a Post-Distribution Ruling or other guidance pursuant to Section 4.03: (A) Exelon shall keep Constellation reasonably informed in a timely manner of all material actions taken or proposed to be taken by Exelon in connection therewith; (B) Exelon shall (i) reasonably in advance of the submission of any documents relating to the ruling provide Constellation with a draft thereof, (ii) reasonably consider Constellation’s comments to such draft, (iii) provide Constellation with a final copy of any documents relating to the ruling, (iv) provide Constellation with notice reasonably in advance of, and Constellation shall have the right to attend, any meetings with the Taxing Authority (subject to the approval of the Taxing Authority) that relate to such ruling, and (v) provide Constellation with a copy of such ruling.

4.04Enforcement. The Parties acknowledge that irreparable harm would occur in the event that any of the provisions of this Article IV were not performed in accordance with their specific terms or were otherwise breached. The Parties agree that, in order to preserve the qualification of the Contribution and the Distribution as a reorganization within the meaning of Sections 368(a)(1)(D) and 355 of the Code, injunctive relief is appropriate to prevent any violation of the foregoing covenants; provided, however, that injunctive relief shall not be the exclusive legal or equitable remedy for any such violation.

Such right to control shall include the right, in the Responsible Party’s reasonable discretion, to waive or extend any statute of limitations in connection with any Tax Controversy and to resolve, settle or agree to any deficiency, claim or adjustment proposed, asserted or assessed in connection with or as a result of any such Tax Controversy; provided, however, that (i) at the request of Exelon or at Constellation’s option, Constellation shall have the right, at its own expense, to reasonably participate (to the extent allowed by Law) in the contest of a Tax Controversy relating to Separation Taxes and Taxes described in Sections 2.02(a)(i)(A) and (C) and (ii) at Exelon’s option, Exelon shall have the right, at its own expense, to reasonably participate (to the extent allowed by Law) in the contest of a Tax Controversy relating to Taxes described in Sections 2.02(a)(ii)(A).

(b)Exelon shall use reasonable efforts to keep Constellation advised as to the status of Tax Controversies involving (i) any issue that relates to a Tax of any member of the Constellation Group or that could reasonably be expected to give rise to a liability of Constellation or any of its Affiliates under this Agreement (in each case, a “Liability Issue”) or (ii) that could reasonably be expected to affect any Tax Attribute of any member of the Constellation Group for any Post-Distribution Period (an “Attribute Issue”). Exelon shall promptly furnish to Constellation copies of any inquiries or requests for information from any Taxing Authority or any other administrative, judicial, or other governmental authority concerning any Liability Issue or Attribute Issue pertaining to Constellation.

For purposes of this Section 5.03(c), Constellation’s share of third party costs and expenses shall be determined by reference to the Constellation Allocable Audit Portion of the total amount Taxes due as a result of such Tax Controversy.

In this regard, the Advisory Firm shall make determinations with respect to the disputed items based solely on representations made by Exelon and Constellation and their respective representatives, and not by independent review, and shall function only as an expert and not as an arbitrator and shall be required to make a determination in favor of one Party only. The Parties shall require the Advisory Firm to attempt to resolve all disputes no later than sixty (60) days after the submission of such dispute to the Advisory Firm, but in no event later than the due date for the payment of Taxes or the filing of the applicable Tax Return, if applicable, and agree that all decisions by the Advisory Firm with respect thereto shall, absent fraud or manifest error, be final and conclusive and binding on the Parties. The Advisory Firm shall resolve all disputes in a manner consistent with this Agreement and, to the extent not inconsistent with this Agreement, in a manner consistent with the past practices of Exelon and its Affiliates, except as otherwise required by applicable Law. The Parties shall require the Advisory Firm to render all determinations in writing to each of the Parties and to set forth, in reasonable detail, the basis for such determination. The fees and expenses of the Advisory Firm shall be paid by the non-prevailing Party. In any action to enforce the final determination of the Advisory Firm, each of the Parties irrevocably and unconditionally (i) consents and submits to the jurisdiction and venue of the courts of the State of Delaware and the federal courts of the United States of America located within the State of Delaware (the “Delaware Courts”); (ii) waives, to the fullest extent it may effectively do so, any objection, including any objection to the laying of venue or based on the grounds of forum non conveniens or any right of objection to jurisdiction on account of its place of incorporation or domicile, which it may now or hereafter have to the bringing of any such action or proceeding in any Delaware Court; (iii) consents to service of process in the manner provided by Section 8.05 (other than delivery by e-mail) or in any other manner permitted by law; and (iv) WAIVES ANY RIGHT TO TRIAL BY JURY.

7.03Arbitration. In order to facilitate the comprehensive resolution of related disputes, all claims between any of the parties to a Dispute that arises under or in connection with both this Agreement, on the one hand, and the Separation Agreement and/or the other Ancillary Agreements, on the other hand, may be brought in a single arbitration in accordance with this Section 7.03. Upon the written request of any party to an arbitration proceeding constituted under both this Agreement, on the one hand, and the Separation Agreement and/or the other Ancillary Agreements, on the other hand, the arbitral tribunal shall consolidate such arbitration proceeding with any other arbitration proceeding relating to this Agreement, on the one hand and the Separation Agreement and/or the other Ancillary Agreements, on the other hand, if the arbitral tribunal determines that (i) there are issues of fact or Law common to the proceedings so that a consolidated proceeding would be more efficient than separate proceedings, and (ii) no party to the Dispute would be unduly prejudiced as a result of such consolidation through undue delay or otherwise. In the event of different rulings on this question by the arbitral tribunal constituted hereunder and another arbitral tribunal constituted under this Agreement, on the one hand, and the Separation Agreement and/or the other Ancillary Agreements, on the other hand, the ruling of the arbitral tribunal constituted first in time shall control, and such arbitral tribunal shall serve as the tribunal for any consolidated arbitration.

7.04Dispute. In the event of a Dispute, each party to the Dispute shall continue to perform its obligations under the Separation Agreement, this Agreement, and the other Ancillary Agreements in good faith during the resolution of such Dispute as if such Dispute had not arisen, unless and until the Separation Agreement, this Agreement, or the other Ancillary Agreements, as applicable, are terminated in accordance with their respective provisions.

Tax Matters Agreement

Schedule B

TAX SHARING AGREEMENT OF TAX CREDIT CARRYFORWARDS

Upon the separation between Exelon Corporation and Constellation, it is expected that Exelon Corporation will have a carryforward of approximately $700,000,000 in general business tax credits from various tax credits under Section 38 of the Internal Revenue Code. Such carryforwards may be used to offset Exelon’s future tax liabilities. As a significant portion of the tax credits were generated by Constellation businesses in pre-separation tax years, Exelon agrees to pay Constellation an annual “tax sharing amount.” This tax sharing amount shall be determined by the amount of carryforward tax credits generated by Constellation businesses in pre-separation tax years that is used to offset Exelon tax in a post-separation tax year, not taking into account any tax credits generated by Exelon in a post-separation tax year. Such tax sharing amount payments shall continue until such time as the carryforward tax credits generated by Constellation businesses in pre-separation tax years are fully exhausted.

Refer to the table below for an illustration.

Post-Separation Year 1
Exelon Tax Liability	100,000,000	A
Maximum Usable Carryforward	75,000,000	B = A x 75%
Exelon Current Year Tax Credit	5,000,000	C
Tax Sharing Amount	70,000,000	D = B - C
