 OBLIGATIONS OF SPONSOR 
 Section 2.01 Equity Contributions. 
 (a) Contributions by
Sponsor. Notwithstanding any provision to the contrary contained herein, the Sponsor hereby agrees, for the benefit of the Collateral Agent on behalf of the Secured Parties, as follows: 
 (i) The Sponsor shall make, or cause to be made through one or more of its direct or indirect subsidiaries, Equity
Contributions to the Borrower (A) as necessary to maintain the Maximum Debt to Equity Ratio at all times and (B) from and after the date on which the proceeds of the Loans have been fully utilized, as necessary to pay all Project Costs as
they are incurred (each such Equity Contribution, in the case of clause (A) or (B), a “Project Cost Funding Contribution”), until an amount equal to the Project Equity Commitment less the Reserve Equity Amount has been
fully funded. Each such Project Cost Funding Contribution shall be made not fewer than two Business Days prior to the date on which such Project Costs are reasonably expected to become due and payable. As of the Closing Date, the Sponsor has made
Equity Contributions equal to $129,940,628, which shall reduce the Project Equity Commitment and the Remaining Equity Commitment. 
  

 6 








 (ii) The Sponsor shall make, or cause to be made through one or more of its
direct or indirect subsidiaries, Equity Contributions to the Borrower in an amount equal to SFF Costs as they are incurred (each such Equity Contribution, an “SFF Funding Contribution”) until the SFF Equity Commitment is funded up
to the maximum amount of $250,000,000. Each such SFF Funding Contribution shall be made not fewer than two Business Days prior to the date on which such SFF Costs are reasonably expected to become due and payable. 
 (iii) The Sponsor shall make, or cause to be made through one or more of its direct or indirect subsidiaries, on or before
the Completion Date, an Equity Contribution to the Borrower in an amount equal to the lesser of (A) an amount sufficient to cause the Debt to Equity Ratio to equal, as of the Completion Date, 1:1 and (B) the then-current unfunded
Project Equity Commitment (such Equity Contribution, the “Completion Date Funding Contribution”). 
 (iv) Upon the occurrence of an Event of Default, the Sponsor shall (subject to the following sentence) make, or cause to be made through one or more of its direct or indirect subsidiaries, an Equity Contribution to the Borrower in an amount
equal to the Remaining Equity Commitment (such Equity Contribution, a “Default Funding Contribution”). Such Default Funding Contribution shall be made not more than two Business Days after receipt by the Sponsor of notice from the
Administrative Agent that an Event of Default has occurred and is continuing and demanding that the Sponsor make, or cause to be made, the Default Funding Contribution; provided, however, that if an Event of Default under
Section 7.01(h) of the TrAILCo Credit Agreement occurs, then such amount shall be due and payable immediately, without notice of any kind. 
 (b) Treatment of Proceeds. Equity Contributions made pursuant to Section 2.01(a) shall be deposited or transferred by the Sponsor as follows: 
 (i) The proceeds of each Project Cost Funding Contribution and each SFF Funding Contribution shall be transferred directly to
the TrAILCo Operating Account. 
 (ii) The proceeds of any Completion Date Funding Contribution and any Default
Funding Contribution shall be transferred directly to the TrAILCo Operating Account, provided that, if for any reason (including due to any Legal Requirement), such amount cannot be transferred to such account, the Sponsor shall cause such
amount to be transferred to the Administrative Agent to be applied in accordance with Section 2.09(b) of the TrAILCo Credit Agreement. 
 Notwithstanding that the Equity Contributions of the Sponsor may be transferred directly to the Administrative Agent, any and all Equity Contributions made by the Sponsor in accordance with the terms hereof shall be deemed to be Equity
Contributions by the Sponsor (or its direct or

  

 7 








 
indirect subsidiary) to the Borrower. Within 15 days following the end of each calendar month, the Sponsor shall provide the Administrative Agent written notice of any Equity Contributions made
during such calendar month, including the amounts of such Equity Contributions. Except as provided herein, all Equity Contributions shall be made without set-off or counterclaim. 
 (c) Maximum Contribution Amount; Increases and Decreases in Equity Commitment. 
 (i) Subject to Section 3.01, in no event shall the Equity Contributions required to be made by the Sponsor pursuant to
this Agreement, when taken together with all purchases of undivided participating interests under Section 4.01, exceed the then-current Remaining Equity Commitment. 
 (ii) The Equity Commitment may be increased, at any time, by the Sponsor delivering to the Collateral Agent and the
Administrative Agent a Commitment Increase Amendment. 
 (iii) If, at any time, FERC or any other Governmental
Authority requires the Borrower to refund all or any portion of any Project Receipt Payment (any such required refund a “Receipt Payment Refund”) previously applied to reduce the amount of the Project Equity Commitment and/or the
Remaining Equity Commitment, then the Project Equity Commitment and/or the Remaining Equity Commitment shall automatically increase by the amount of such Receipt Payment Refund made by the Borrower (without duplication of Receipt Payment Refunds
that limit the reduction of the Project Equity Commitment pursuant to Section 2.01(c)(iv)). 
 (iv) If the
Borrower (A) has designated all or any portion of the Prexy Segment, the Virginia Segment or the Jointly Owned Segment as an Excluded Portion (and such portion qualifies as an “Excluded Portion” pursuant to the terms of the TrAILCo
Credit Agreement), (B) has reduced the Lenders’ Construction Loan commitments by an amount equal to (1) the Allocated Loan Amount for such Segment minus (2) the Excluded Portion Loan Amount for such Segment,
provided that if less than all of such Segment is designated as an Excluded Portion, then such reduction shall be made in proportion to the amount budgeted for such Excluded Portion relative to the Allocated Loan Amount for such Segment (as
certified by the Borrower and confirmed by the Independent Engineer), (C) has certified that it shall not spend any further funds on such Excluded Portion (provided that, the Borrower may, at a later date, determine to make additional
expenditures in respect of such Excluded Portion with the proceeds of equity contributions if such Excluded Portion meets the criteria for a Separately Financed Facility) and (D) cannot reasonably be expected to be required by FERC or any other
Governmental Authority to continue construction or to decommission (or otherwise perform any other remediation), in each case with respect to such Excluded Portion, then the Project Equity Commitment may be reduced by (X) the portion of the
total Project Equity Commitment (including any contingency associated therewith) allocable to such Excluded Portion, such portion to be determined based on the amount budgeted for such Excluded Portion (including any contingency associated
therewith) in the Project Budget relative to the total Project Budget less (Y) the sum of (1) the Excluded Portion Loan

  

 8 








 
Amount for such Excluded Portion plus (2) the amount of any Receipt Payment Refund made by the Borrower and not previously used in calculating an adjustment to the Project Equity
Commitment with respect to another Excluded Portion pursuant to this Section 2.01(c)(iv) plus (3) the amount of Equity Contributions already contributed or deemed contributed in connection with such Excluded Portion. For the
avoidance of doubt, if less than all of a Segment is designated as an Excluded Portion, then such reduction shall be made in proportion to the total Project Equity Commitment (including any contingency associated therewith) allocable to such portion
of the Segment, such portion to be determined based on the amount budgeted for such portion of such Segment (including any contingency associated therewith) relative to the total Project Equity Commitment (including any contingency associated
therewith) allocable to such Segment (as certified by the Borrower and confirmed by the Independent Engineer). Such reduction of the Project Equity Commitment shall be made by the Sponsor delivering to the Collateral Agent and the Administrative
Agent a Commitment Decrease Amendment. 
 (v) For any Separately Financed Facility for which the Sponsor is
obligated to make equity contributions to the Borrower, if the Borrower has (A) certified that it shall not spend any further funds on such Separately Financed Facility and (B) cannot reasonably be expected to be required by FERC or any
other Governmental Authority to continue construction or to decommission (or otherwise perform any other remediation), in each case with respect to such Separately Financed Facility, then the SFF Equity Commitment may be reduced by the equity amount
allocated to such Separately Financed Facility, less the amount already spent on such Separately Financed Facility. Such reduction of the SFF Equity Commitment shall be made by the Sponsor delivering to the Collateral Agent and the Administrative
Agent a Commitment Decrease Amendment. 
 (d) Interim Equity Contributions. If the Sponsor makes Equity Contributions
during any period when Loans are not available to the Borrower for use to pay Project Costs for any Segment because the Borrower has not obtained Siting Approval for such Segment and has drawn up to the Approved Limit for such Segment, and such
Equity Contributions are applied to pay Project Costs for such Segment, then such Equity Contributions shall be deemed to be “Interim Equity Contributions” and shall not reduce the Remaining Equity Commitment (nor shall they be
credited to reduce the Sponsor’s Project Equity Commitment or SFF Equity Commitment); provided, however, that if the Borrower subsequently obtains Siting Approval for such Segment, then the Sponsor shall be credited with having
made Equity Contributions that reduce the Remaining Equity Commitment (and that shall be credited toward the Sponsor’s Project Equity Commitment) in an amount equal to such Interim Equity Contributions less any amounts distributed to the
Sponsor or any of its Affiliates with the proceeds of Loans made to reimburse the Sponsor for a portion of such Interim Equity Contributions in accordance with the terms of the TrAILCo Credit Agreement (including the requirement that the Borrower
maintain the Maximum Debt to Equity Ratio). 
 Section 2.02 Late Payments. In the event that any Equity Contribution
is not made on the date such Equity Contribution is required to be made hereunder, the amount of such delinquent Equity Contribution shall bear interest at a per annum rate equal to 2% plus the

  

 9 








 
interest rate then applicable to Base Rate Loans as provided in Section 2.12(a) of the TrAILCo Credit Agreement until such time as such Equity Contribution is deposited in the TrAILCo
Operating Account or transferred to the Administrative Agent in accordance with Section 2.01. 
 Section 2.03
Waiver of Defenses; Obligations Unconditional. 
 (a) Waiver of Defenses. To the extent permitted by applicable
Legal Requirements, the Sponsor hereby unconditionally and irrevocably waives and relinquishes all rights and remedies accorded by applicable Legal Requirements to sureties or guarantors and agrees not to assert or take advantage of any such rights
or remedies, including (i) any right to require the Collateral Agent or any Secured Party to proceed against the Borrower or any other person or to proceed against or exhaust any security held by the Collateral Agent or any other Secured Party
at any time or to pursue any other remedy in the Collateral Agent’s or any Secured Party’s power before proceeding against the Sponsor, (ii) any defense that may arise by reason of the incapacity, lack of power or authority, death,

proceeding) of the Borrower or any other person, (iii) demand, presentment, protest and notice of any kind (other than any notice required pursuant to the express provisions of this Agreement), including notice of the existence, creation or

this or any other instrument in connection with any obligation or evidence of Indebtedness held by the Collateral Agent or any Secured Party as collateral or in connection with any of the Obligations, (iv) any defense based upon an election of
remedies by the Collateral Agent or the Secured Parties, including an election to proceed by non-judicial rather than judicial foreclosure, which destroys or otherwise impairs the subrogation rights of the Sponsor, the right of the Sponsor to
proceed against the Borrower or another person for reimbursement, or both, (v) any defense based on any offset against any amounts which may be owed by any person to the Sponsor or the Borrower for any reason whatsoever, (vi) any defense

under the Construction Contract, the TrAILCo Credit Agreement or the other Transaction Document, (ix) any duty on the part of the Collateral Agent or any Secured Party to disclose to the Sponsor any facts the Collateral Agent or any Secured
Party may now or hereafter know about the Borrower, regardless of whether the Collateral Agent or any Secured Party has reason to believe that any such facts materially increase the risk beyond that which the Sponsor intends to assume, or have
reason to believe that such facts are unknown to the Sponsor, or have a reasonable opportunity to communicate such facts to the Sponsor, since the Sponsor acknowledges that the Sponsor is fully responsible for being and keeping informed of the
financial condition of the Borrower, (x) any defense based on any change in the time,

  

 10 








 
manner or place of any payment under, or in any other term of, the Construction Contract, the TrAILCo Credit Agreement or any other Transaction Document or any other amendment, renewal,

Agent’s or any Secured Party’s election, in any proceeding instituted under the U.S. Bankruptcy Code, of the application of Section 1111(b)(2) of the U.S. Bankruptcy Code, (xii) any defense based upon any borrowing or grant of a
security interest under Section 364 of the U.S. Bankruptcy Code and (xiii) any other circumstance (including any statute of limitations) or any existence of or reliance on any representation by the Collateral Agent or any Secured Party

 (b) Obligations Unconditional. All rights of the Collateral Agent and the Secured Parties and all obligations of the Sponsor
hereunder shall be absolute and unconditional irrespective of:

failure of any Secured Party (i) to assert any claim or demand or to enforce any right or remedy against the Borrower, the Sponsor or any other Person (including any guarantor) under the provisions of the Construction Contract, the TrAILCo
Credit Agreement, any other Financing Document or otherwise, or (ii) to exercise any right or remedy against any other guarantor of, or collateral securing, any of the Obligations;

limitation, impairment or termination of any of the Obligations for any reason other than the written agreement of the Secured Parties to terminate the Obligations in full, including any claim of waiver, release, surrender, alteration or compromise,
and shall not be subject to, and the Sponsor hereby waives any right to or claim of, any defense or setoff, counterclaim, recoupment, or termination whatsoever by reason of the invalidity, illegality, nongenuineness, irregularity, compromise,
unenforceability of, or any other event or occurrence affecting, any Obligation of the Borrower, the Sponsor or otherwise; 
 (v) any amendment to, rescission, waiver, or other modification of, or any consent to departure from, any of the terms of the Construction Contract, the TrAILCo Credit Agreement, this Agreement (other

the Borrower, the Sponsor, any surety or any guarantor (in each of the foregoing cases other than the defense, subject to Section 3.01, of payment of the applicable amounts). 
 Section 2.04 Incremental Facility. Each time any New Construction Commitment is established pursuant to Section 2.19 of the
Credit Agreement, the Sponsor shall, concurrently therewith, make an Equity Contribution to the Borrower in an amount equal to (x) such New Construction Commitment minus (y) the amount of Project Receipt Payments not previously applied to
reduce Equity Contributions hereunder net of all accounts payable in respect of Project Costs during the next 45-day period (for the avoidance of doubt, the amount calculated pursuant to this clause (y) shall not be less than zero). 

Section 2.05 Subrogation. So long as any of the Obligations remain outstanding (other than those contingent Obligations that
are intended to survive the termination of, as applicable, the TrAILCo Credit Agreement, the other Financing Documents or any other applicable documents), (a) the Sponsor shall not have any right of subrogation and the Sponsor waives all rights
to enforce any remedy which the Collateral Agent or the other Secured Parties now have or may hereafter have against the Borrower or AET that arises hereunder or from the performance by the Sponsor hereunder, and waives the benefit of, and all
rights to participate in, any security now or hereafter held by the Collateral Agent (for the benefit of the Secured Parties) from the Borrower or AET, and (b) the Sponsor waives any claim, right or remedy which the Sponsor may now have or
hereafter acquire against the Borrower or AET that arises hereunder or from the performance by the Sponsor hereunder, including any claim, remedy or right of subrogation, reimbursement, exoneration, contribution, indemnification, or participation in
any claim, right or remedy of the Collateral Agent or the other Secured Parties against Borrower or AET or any security or collateral which the Collateral Agent or the other Secured Parties now have or hereafter acquire, whether or not such claim,
right or remedy arises in equity, under contract, by statute, under common law or otherwise. Any amount paid to the Sponsor on account of any such subrogation rights prior to the payment in full in cash of the Obligations and the termination of all
Commitments and other obligations of the Collateral Agent and the other Secured Parties (other than those contingent Obligations that are intended to survive the termination of, as applicable, the TrAILCo Credit Agreement, the other Financing
Documents or any other applicable documents) shall be held in trust for the benefit of the Collateral Agent and shall immediately thereafter be paid to the Collateral Agent for application in accordance with this Agreement and the TrAILCo Credit
Agreement. 
 ARTICLE III.

made pursuant to this Agreement is rescinded or otherwise restored to the Sponsor, whether as a result of any proceedings in bankruptcy or reorganization or otherwise with respect to Borrower or
any other person or as a result of any settlement or compromise with any person (including the Sponsor) in respect of such payment, and the Sponsor shall pay the Collateral Agent on demand all of its reasonable and documented out-of-pocket costs and
expenses (including reasonable and documented fees of outside counsel) incurred by the Collateral Agent in connection with such rescission or restoration. 
 Section 3.02 Specific Performance. The Sponsor hereby irrevocably waives, to the extent the Sponsor may do so under applicable Legal Requirements, any defense based on the adequacy of a remedy
at law that may be asserted as a bar to the remedy of specific performance in any action brought against the Sponsor for specific performance of this Agreement by the Collateral Agent or any successor or assign thereof or for its benefit by a
receiver, custodian or trustee appointed for the Borrower or in respect of all or a substantial part of its assets, under the bankruptcy or insolvency laws of any jurisdiction to which the Borrower or its assets are subject. 
 Section 3.03 Commencement of Bankruptcy Proceedings. None of the obligations of the Sponsor under this Agreement shall be
altered, limited or affected by any proceeding, voluntary or involuntary, involving the bankruptcy, reorganization, insolvency, receivership, liquidation or arrangement of the Borrower or the Sponsor, or by any defense which the Borrower or the
Sponsor may have by reason of any order, decree or decision of any court or administrative body resulting from any such proceeding. 
 Section 3.04 Set-Off. In addition to any rights now or hereafter granted under applicable Legal Requirements or otherwise, and not by way of limitation of any such rights, upon the failure of the Sponsor to make any Equity
Contribution as and when required hereunder, the Collateral Agent is hereby authorized at any time or from time to time, without presentment, demand, protest or other notice of any kind to the Sponsor or to any other person, any such notice being
hereby expressly waived, to set-off and to appropriate and apply any and all deposits (general or special) at any time held by the Collateral Agent or any Secured Party (including by branches and agencies of the Collateral Agent and each Secured
Party wherever located) to or for the credit or the account of the Sponsor, against and on account of the obligations of the Sponsor under this Agreement, irrespective of whether or not the Collateral Agent or any Secured Party shall have made any
demand hereunder. 
 ARTICLE IV. 
 PURCHASE OF PARTICIPATING INTEREST 
 Section 4.01 Required Purchase
of Participating Interest. If by reason of any act of a Governmental Authority or as a result of the Borrower or any of its Affiliates being Insolvent, (a) any Equity Contribution due hereunder has not been deposited in the TrAILCo
Operating Account or paid to the Administrative Agent, as applicable, within five Business Days after the date on which such amount is payable hereunder, or (b) any Equity Contribution theretofore deposited pursuant to Article II is rescinded
or otherwise restored to the Sponsor or any of its Affiliates and five Business Days have elapsed after the date that such Equity Contribution was rescinded or otherwise restored (such Equity Contribution, whether required but not made as provided
in clause (a) or made and returned as provided in clause (b), being

  

 13 








 
herein called the “Defaulted Payment”), the Sponsor shall, upon notice or demand by the Collateral Agent or any Secured Party, purchase an undivided participating interest in
each of the Loans which shall then be outstanding, as provided in the following sentence, in an aggregate principal amount equal to the amount of the Defaulted Payment. The Sponsor’s purchase of an undivided participating interest in such Loans
shall be made pro rata among such Loans based on the respective outstanding amounts thereof. The Sponsor shall effect its purchase of undivided participating interests in such Loans pursuant to this Section 4.01 by paying to the
Administrative Agent, for the account of the holders of such Loans, in immediately available funds in Dollars, the amount of the Defaulted Payment and by entering into the documentation required for participations in or assignments of the Loans, as
set forth in the TrAILCo Credit Agreement. 
 Section 4.02 Effect of Purchase of Participating Interest. The
Sponsor’s purchase of an undivided participating interest in the Loans in the full amount (if any) required pursuant to Section 4.01 following a Defaulted Payment in respect of Equity Contributions, shall satisfy the Sponsor’s
obligation pursuant to Section 2.01 to make Equity Contributions to the extent of the amount of such Loans so purchased by the Sponsor. 
 Section 4.03 Subordinate Nature of Participating Interest. The Sponsor hereby agrees that its participating interest in the Loans purchased by the Sponsor pursuant to Section 4.01 shall
be subordinate in all respects to the interest in such Loans retained by the holders (other than the Sponsor) thereof (the “Retained Interest”), so that all payments received or collected on account of such Loans and applied to the
payment or termination thereof, whether received or collected through repayment of such Loans by the Borrower or through right of set-off with respect thereto or realization upon any collateral security therefor or otherwise, shall first be applied
to the payment of the principal, interest, fees and other amounts then due (whether at its stated maturity, by acceleration or otherwise) on the Retained Interest until such principal, interest, fees and other amounts are paid in full, before any
such payments are applied on account of the Sponsor’s participating interest (if any) in such Loans. 
 Section 4.04
Rights of Agents and the Secured Parties. Notwithstanding the purchase and ownership by the Sponsor of participating interests in the Loans, and notwithstanding the rights of participants under the TrAILCo Credit Agreement, the Collateral
Agent and, to the extent permitted, each Secured Party shall have the right, in their sole discretion in each instance and without any notice to the Sponsor, (a) to agree to the modification or waiver of any of the terms of any of the Financing
Documents or any other agreement or instrument relating thereto (but not to reduce any amount payable in respect of the portion of the Loans subject to participations purchased pursuant to Section 4.01), (b) to consent to any action or
failure to act by the Borrower, the Sponsor or any other person party to a Financing Document and (c) to exercise or refrain from exercising any rights or remedies which the Collateral Agent or any Secured Party may have under the Financing
Documents or any other agreement or instrument relating thereto, including the right at any time to declare, or refrain from declaring, the Obligations due and payable upon the occurrence of any Event of Default thereunder, and to rescind and annul
any such declaration, and to foreclose and sell or exercise any other remedy, or refrain from foreclosing and selling or exercising any other remedy, with respect to any Collateral securing the Obligations. Neither the Collateral Agent nor any
Secured Party shall be

  

 14 








 
liable to the Sponsor for any error in judgment or for any action taken or omitted to be taken by the Sponsor while the Sponsor holds a participating interest in the Loans, except to the extent
found in a final and non-appealable judgment of a court of competent jurisdiction to have resulted primarily from the gross negligence or willful misconduct of such person. Neither the Collateral Agent nor any Secured Party shall have any duty or
responsibility to provide the Sponsor with any credit or other information concerning the affairs, financial condition or business of the Borrower or any other party to a Financing Document or which may come into their possession or the possession
of any of their respective Affiliates, or to notify the Sponsor of any default by the Borrower or any other person under any of the Financing Documents. 
 Section 4.05 No Voting Rights. Without limiting the generality of the provisions of Section 4.04, in determining whether the required consent of the Lenders (or any portion thereof) has
been obtained for all purposes under the Financing Documents the participating interests in the Loans purchased by the Sponsor pursuant to Section 4.01 shall not be deemed to be outstanding. 
 Section 4.06 Outright Purchase; Obligations Unconditional. The obligations of the Sponsor under this Article IV to purchase
participating interests in the Loans is absolute and unconditional and shall not be affected by the occurrence of any Default or Event of Default or any other circumstance, including any circumstance of the nature described in Section 2.03.

 ARTICLE V.

 Section 5.02 Organization; Power and Authority. The execution, delivery and performance of this Agreement has been duly
authorized by all necessary corporate action on the part of the Sponsor, and this Agreement constitutes a legal, valid and binding obligation of the Sponsor, enforceable against the Sponsor in accordance with its terms, except as such enforceability

certificates or other writings delivered to the Lenders by or on behalf of the Sponsor regarding the Sponsor, including

  

 15 








 
information regarding the Sponsor set forth in the Information Memorandum, taken as a whole, do not contain any untrue statement of a material fact or omit to state any material fact necessary to
make the statements therein (taken as a whole) not materially misleading in light of the circumstances under which they were made. There is no fact known to the Sponsor that could reasonably be expected to have a “Material Adverse Effect”
(as defined in the TrAILCo Credit Agreement) that has not been set forth in the Information Memorandum, the Financing Documents or in the other documents, certificates and other writings delivered by or on behalf of the Sponsor or the Borrower.

 (b) Since December 31, 2007, there has been no change in the financial condition, operations, business or properties of
the Sponsor except changes that individually or in the aggregate could not reasonably be expected to have a Material Adverse Effect. 
 Section 5.04 Financial Statements. The financial statements of the Sponsor (including the related schedules and notes) delivered to the Lenders pursuant to Section 4.01(i) of the TrAILCo Credit Agreement fairly present in
all material respects the financial position of the Sponsor, as of their respective dates and the results of its operations and cash flows for the respective periods then ended and have been prepared in accordance with GAAP consistently applied
throughout the periods involved except as set forth in the notes thereto (subject, in the case of any interim financial statements, to normal year-end adjustments and the absence of footnotes). 
 Section 5.05 No Conflict. The execution, delivery and performance by the Sponsor of this Agreement will not (a) result in
the creation of any Lien (other than any Permitted Lien) in respect of any property of the Sponsor or (b) conflict with or result in a breach of any of the terms, conditions or provisions of any order, judgment, decree, or ruling of any court,
arbitrator or Governmental Authority applicable to the Sponsor. 
 Section 5.06 Authorization; Enforceable
Obligations. No authorization or approval or other action by, and no notice to or filing with, any Governmental Authority or any other third party is required in connection with the due execution, delivery, recordation, filing or performance by
the Sponsor, or the validity or enforceability as to the Sponsor, of this Agreement, except for authorizations, approvals, actions, notices and filings which have been duly obtained, taken, given or made, are in full force and effect, are held in
its name, and are free from any conditions or requirements that have not been satisfied, and are required to be satisfied, on or prior to the dates as of which this representation and warranty is made or reaffirmed. 
 Section 5.07 Execution and Delivery. This Agreement has been duly executed and delivered by the Sponsor.

Subsidiaries or any of their respective properties to the knowledge of the Sponsor or to its knowledge, pending (but not yet commenced) against or threatened against, the Sponsor

  

 16 








 
or any of its Subsidiaries or any of their respective properties before any Governmental Authority that (i) except for Disclosed Matters, if adversely determined, could reasonably be
expected to have a Material Adverse Effect (other than matters described on Schedule 5.09 (the “Disclosed Litigation”)) or (ii) affects or could reasonably be expected to affect the legality, validity or enforceability of this
Agreement or the performance by the Sponsor of its obligations hereunder. 
 (b) To the extent that the representation and
warranty in Section 5.09(a) conforms to the representation and warranty in Section 4.01(e) of the Sponsor Credit Agreement or any other provision of any Sponsor Financing Document, if such corresponding representation and warranty in such
Sponsor Financing Document is amended, supplemented, restated, waived or otherwise modified (whether in connection with an amendment, supplement, restatement, waiver or other modification of, or a replacement of, such Sponsor Financing Document,
including as a result of a refinancing transaction), then Section 5.09(a) shall be deemed to be amended, supplemented, restated, waived, modified or replaced such that it conforms to the corresponding representation and warranty in such Sponsor
Financing Document (after giving effect to such amendment, supplement, restatement, waiver, modification or replacement). For the avoidance of doubt, if, as a result of this provision, the representation and warranty contained in
Section 5.09(a) as of the date of this Agreement is deemed to have been deleted and a subsequent amendment of, supplement to, other modification of or replacement of any Sponsor Financing Document contains a representation and warranty that
clearly corresponds to such deleted representation and warranty, then such deleted representation and warranty shall be deemed to be reinstated (such that it conforms to the corresponding representation and warranty as in effect in the then current
Sponsor Financing Document).

be reasonably likely to have a Material Adverse Effect. Schedule B (Actuarial Information) to the most recent annual report (Form 5500 Series) for each Plan, filed with the Internal Revenue Service is complete and accurate, and since the date of
such Schedule B there has been no material adverse change which could reasonably be expected to have a Material Adverse Effect on such funding status. Except as could not reasonably be expected to have a Material Adverse Effect, neither the Sponsor
nor any ERISA Affiliate (i) has incurred any Withdrawal Liability to any Multiemployer Plan, or (ii) has been notified by the sponsor of a Multiemployer Plan that such Multiemployer Plan is in reorganization or has been terminated, within
the meaning of Title IV of ERISA.

circumstances exist that could reasonably be expected to (A) form the basis of an Environmental Action against the Sponsor or any of its Subsidiaries or any of their properties or (B) cause any such property to be subject to any

 Section 6.04 Revisions to Sponsor Financing Documents. 
 (a) Existing Covenants. To the extent that any covenant set forth in Section 6.01, 6.02 or 6.03 conforms to a corresponding
covenant in the Sponsor Credit Agreement or any other Sponsor Financing Document, if such corresponding covenant in such Sponsor Financing Document is amended, supplemented, restated, waived or otherwise modified (whether in connection with an
amendment, supplement, restatement, waiver or other modification of, or a replacement of, such Sponsor Financing Document, including as a result of a refinancing transaction), then the relevant covenant in this Agreement shall be deemed to be
amended, supplemented, restated, waived, modified or replaced such that it conforms to the corresponding covenant in such Sponsor Financing Document (after giving effect to such amendment, supplement, restatement, waiver, modification or
replacement); provided, however, that none of the covenants set forth in Sections 6.01(c), 6.01(j)(ii), 6.03(b), 6.03(c) or 6.03(f), shall be deemed amended, supplemented, restated, waived, modified or replaced at any time as a result
of anything set forth in this Section 6.04; provided further that the covenants set forth in Sections 6.03(b) and 6.03(c) shall remain in effect notwithstanding any deletion or expiration of the corresponding covenants in the
Sponsor Credit Agreement or the termination or expiration of the Sponsor Credit Agreement. For the avoidance of doubt, if, as a result of this provision, any covenant contained in this Agreement as of the date of this Agreement is deemed to have
been deleted and a subsequent amendment of, supplement to, other modification of or replacement of any Sponsor Financing Document contains a covenant that clearly corresponds to such deleted covenant, then such deleted covenant shall be deemed to be
reinstated (such that it conforms to the corresponding covenant as in effect in the then current Sponsor Financing Document). 
 (b) For the avoidance of doubt, Sections 6.02(a), 6.02(b), 6.02(c), 6.02(d), 6.02(e), 6.02(f), 6.02(g), 6.02(h), 6.02(i), 6.02(j) and 6.02(k), respectively, shall be interpreted and construed to be amended, supplemented, restated, waived or
otherwise modified in connection with any amendment, supplement, restatement, waiver or other modification of Sections 5.02(b), 5.02(c), 5.02(d), 5.02(e), 5.02(f), 5.02(g), 5.02(h), 5.02(k), 5.02(l), 5.02(m) and 5.04 of the Sponsor Credit Agreement,
respectively, as applicable, or any other applicable covenant that corresponds to such covenant in any successor Sponsor Financing Document. 
 (c) New Covenants. To the extent that any covenant is added as a covenant in the Sponsor Credit Agreement or any other Sponsor Financing Document after the date hereof, then this Agreement shall be
deemed amended and such covenant shall be deemed to be incorporated as a new covenant hereunder. Any Event of Default resulting from the breach of any such new covenant by the Sponsor shall be subject to the same cure period as would be applicable
under the relevant provision in the applicable Sponsor Financing Document. 
  

 24 








 ARTICLE VII.

 (f) the Sponsor or any of its Subsidiaries shall fail to perform or observe any other covenant or agreement (not specified in
Sections 7.01(a), 7.01(b), 7.01(d) or 7.01(e) above) contained in this Agreement on its part to be performed or observed and such failure shall remain unremedied for 60 days after the date on which a Responsible Officer of the Sponsor becomes aware

giving of notice if required, (1) such Indebtedness to be demanded, become due, repurchased, prepaid, defeased or redeemed (automatically or otherwise), (2) an offer to repurchase,
prepay, defease or redeem such Indebtedness to be made, prior to its stated maturity, or (3) cash collateral in respect thereof to be demanded; or (ii) there occurs under any Hedge Agreement an Early Termination Date (as defined in such
Hedge Agreement) resulting from (A) any Event of Default under such Hedge Agreement as to which the Sponsor or any Subsidiary is the Defaulting Party (as defined in such Hedge Agreement) or (B) any Termination Event (as so defined) under
such Hedge Agreement as to which the Sponsor or any Subsidiary is an Affected Party (as defined in such Hedge Agreement) and, in either event, the termination value owed by the Sponsor or such Subsidiary as a result thereof is greater than the
$40,000,000 either individually or in the aggregate; or 
 (h) Any Insolvency Proceeding shall occur with respect to the Sponsor
or any Subsidiary; or 
 (i) there is entered against the Sponsor or any of its Subsidiaries (i) any final judgment or
order for the payment of money in an amount exceeding $40,000,000 either individually or in the aggregate (to the extent not covered by independent third-party insurance by an insurer that is rated at least “A” by A.M. Best Company and
such coverage is not the subject of a bona fide dispute), or (ii) one or more non-monetary final judgments that have, or could reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect and, in the case of
(i) or (ii), (A) enforcement proceedings are commenced by any creditor upon such judgment or order and such proceedings are not stayed within 10 Business Days, or (B) there is a period of 30 consecutive days during which a stay of
enforcement of such judgment, by reason of a pending appeal or otherwise, is not in effect; or 
 (j) any material provision of
this Agreement shall be canceled, terminated, declared to be null and void or shall otherwise cease to be valid and binding on the Sponsor, in each case, as determined in a final, non-appealable judgment of a court of competent jurisdiction, or the
Sponsor shall deny in writing any further liability or obligation under any provision of this Agreement; provided, however, that the foregoing provisions of this clause (j) shall not apply to this Agreement to the extent that it
is canceled, terminated, declared to be null and void or ceases to be valid or binding on the Sponsor in accordance with its terms or by agreement of the parties hereto; or 
 (k) a Change of Control shall occur; or 
 (l) as a result of, or in connection with, an ERISA Event that shall have occurred with respect to a Plan, the Sponsor or any Subsidiary (as defined in the Sponsor Credit Agreement) or any ERISA Affiliate
has incurred or is reasonably expected to incur liability in an amount exceeding, in the aggregate with any amounts applicable under clauses (m) and (n) of this Section 7.01, $25,000,000; or 
 (m) the Sponsor, any of its Subsidiaries (as defined in the Sponsor Credit Agreement) or any ERISA Affiliate shall have been notified by the
sponsor of a Multiemployer Plan that the Sponsor has incurred Withdrawal Liability to such Multiemployer Plan in an amount that, when aggregated with all other amounts required to be paid to Multiemployer Plans

  

 26 








 
by the Sponsor, any such Subsidiaries and the ERISA Affiliates as Withdrawal Liability (determined as of the date of such notification), exceeds, in the aggregate with any amounts applicable
under clauses (l) and (n) of this Section 7.01, $25,000,000 or requires payments exceeding $25,000,000 per annum; or 
 (n) the Sponsor or any of its Subsidiaries (as defined in the Sponsor Credit Agreement) or any ERISA Affiliate shall have been notified by the sponsor of a Multiemployer Plan that such Multiemployer Plan

 Notwithstanding anything to the contrary set forth in this Agreement, in the case of an Event of Default resulting from the corresponding
default or event of default (if applicable) under the Sponsor Financing Documents, no such Event of Default shall be deemed to exist if such corresponding default or event of default has been waived by the “Required Lenders” or
“Lenders” (each as defined in the Sponsor Financing Documents) pursuant to the Sponsor Financing Documents. 
 The
Collateral Agent shall have no duty or obligation to ascertain or inquire into the existence or non-existence of any default or event of default under the Sponsor Credit Agreement. The Collateral Agent shall be entitled to rely exclusively on any
written notice delivered by the Administrative Agent stating that any default or event of default under the Sponsor Credit Agreement exists or does not exist.

other modification of, or a replacement of, such Sponsor Financing Document, including as a result of a refinancing transaction), then the relevant Event of Default in Section 7.01 of this Agreement shall be deemed to be amended, supplemented,
restated, waived, modified or replaced such that it conforms to the corresponding event of default provision in such Sponsor Financing Document (after giving effect to such amendment, supplement, restatement, waiver, modification or replacement).
For the avoidance of doubt, if, as a result of this provision, any Event of Default in Section 7.01 of this Agreement as of the date of this Agreement is deemed to have been deleted and a subsequent amendment of, supplement to, other
modification of or replacement of any Sponsor Financing Document contains an event of default provision that clearly corresponds to such deleted Event of Default, then such deleted Event of Default shall be deemed to be reinstated (such that it
conforms to the corresponding event of default provision as in effect in the then current Sponsor Financing Document).
