of any 

  
 - 7 - 








 
Excluded Project Subsidiary in the Development Stage) as of such date to (y) the aggregate amount of Consolidated Adjusted EBITDA of all Restricted Subsidiaries (excluding Consolidated
Adjusted EBITDA of any Excluded Projected Subsidiary in the Development Stage) for the period of the most recent four consecutive fiscal quarters ending prior to the date of such determination for which financial statements prepared on a
consolidated basis in accordance with GAAP are available, provided, however, that: 
 (1) if any Restricted Subsidiary: 

(a) has Incurred any Indebtedness since the beginning of such period that remains outstanding on such date of determination or
if the transaction giving rise to the need to calculate the Combined Leverage Ratio includes an Incurrence of Indebtedness, Consolidated Adjusted EBITDA and Consolidated Indebtedness for such period will be calculated after giving effect on a pro
forma basis to such Indebtedness as if such Indebtedness had been Incurred on the first day of such period (except that in making such computation, the amount of Indebtedness under any revolving Debt Facility outstanding on the date of such
calculation will be deemed to be (i) the average daily balance of such Indebtedness during such four fiscal quarters or such shorter period for which such facility was outstanding or (ii) if such facility was created after the end of such
four fiscal quarters, the average daily balance of such Indebtedness during the period from the date of creation of such facility to the date of such calculation) and the discharge of any other Indebtedness repaid, repurchased, redeemed, retired,
defeased or otherwise discharged with the proceeds of such new Indebtedness as if such discharge had occurred on the first day of such period; or 

(b) has repaid, repurchased, redeemed, retired, defeased or otherwise discharged any Indebtedness since the beginning of the
period that is no longer outstanding on such date of determination or if the transaction giving rise to the need to calculate the Combined Leverage Ratio includes a discharge of Indebtedness (in each case, other than Indebtedness Incurred under any
revolving Debt Facility unless such Indebtedness has been permanently repaid and the related commitment terminated and not replaced), Consolidated Adjusted EBITDA and Consolidated Indebtedness for such period will be calculated after giving effect
on a pro forma basis to such discharge of such Indebtedness, including with the proceeds of such new Indebtedness, as if such discharge had occurred on the first day of such period; 

(2) if since the beginning of such period, any Restricted Subsidiary will have made any Asset Disposition or disposed of or discontinued (as
defined under GAAP) any company, division, operating unit, segment, business, group of related assets or line of business or if the transaction giving rise to the need to calculate the Combined Leverage Ratio includes such a transaction, the
Consolidated Adjusted EBITDA for such period shall be reduced by an amount equal to the Consolidated Adjusted EBITDA (if positive) directly attributable to the assets that are the subject of such disposition or discontinuation for such period or
increased by an amount equal to the Consolidated Adjusted EBITDA (if negative) directly attributable thereto for such period; 

  
 - 8 - 








 (3) if since the beginning of such period the Company or any Restricted Subsidiary (by merger or
otherwise) (a) will have made an Investment in any Restricted Subsidiary (or any Person that becomes a Restricted Subsidiary or is merged with or into a Restricted Subsidiary) or (b) an acquisition of assets, including any acquisition of
assets occurring in connection with a transaction causing a calculation to be made hereunder, which constitutes all or substantially all of a company, division, operating unit, segment, business, group of related assets or line of business,
Consolidated Adjusted EBITDA for such period will be calculated after giving pro forma effect thereto (including the Incurrence of any Indebtedness) as if such Investment or acquisition occurred on the first day of such period; and 

(4) if since the beginning of such period any Person (that subsequently became a Restricted Subsidiary or was merged with or into any
Restricted Subsidiary since the beginning of such period) will have Incurred any Indebtedness or discharged any Indebtedness, made any disposition or any Investment or acquisition of assets that would have required an adjustment pursuant to clause
(1), (2) or (3) above if made by a Restricted Subsidiary during such period, Consolidated Adjusted EBITDA and Consolidated Indebtedness for such period will be calculated after giving pro forma effect thereto as if such transaction
occurred on the first day of such period. 
 For purposes of this definition, whenever pro forma effect is to be given to any calculation
under this definition, the pro forma calculations will be determined in good faith by a responsible financial or accounting officer of the Company (including pro forma expense and cost reductions calculated on a basis consistent with Regulation S-X under the Securities Act). If any Indebtedness bears a floating rate of interest and is being given pro forma effect, the interest expense on such Indebtedness will be calculated as if the rate in effect on the
date of determination had been the applicable rate for the entire period (taking into account any Interest Rate Agreement applicable to such Indebtedness if such Interest Rate Agreement has a remaining term in excess of 12 months). If any
Indebtedness that is being given pro forma effect bears an interest rate at the option of any Restricted Subsidiary, the interest rate shall be calculated by applying such optional rate chosen by such Restricted Subsidiary. 

“Commodity Agreement” means any long-term or forward purchase contract or option contract to buy, sell or exchange
commodities, commodity futures contract, commodity swap, commodity option or other similar agreement or arrangement entered into by the Company or any Restricted Subsidiary designed to protect the Company or any of its Restricted Subsidiaries
against fluctuations in the price of commodities in the ordinary course of business of the Company and its Restricted Subsidiaries. 

“Common Stock” means with respect to any Person, any and all shares, interest or other participations in, and other
equivalents (however designated and whether voting or nonvoting) of such Person’s common stock whether or not outstanding on the Issue Date, and includes, without limitation, all series and classes of such common stock. 

  
 - 9 - 








 “Consolidated Adjusted EBITDA” means, with respect to any Person for any period,
the Consolidated Net Income of such Person for such period: 
 (1) increased (without duplication) by the following items to the extent
deducted in calculating such Consolidated Net Income: 
 (a) Consolidated Interest Expense; plus 

(b) Consolidated Income Taxes; plus 

(c) consolidated depreciation expense; plus 

(d) consolidated amortization expense or impairment charges recorded in connection with the application of ASC 350,
Intangibles—Goodwill and Other, and ASC 360, Property, Plant and Equipment;” plus 
 (e) Transaction Costs
and all legal, accounting and other expenses incurred in connection with the Transactions or any acquisitions or Investments permitted under this Fourth Supplemental Indenture to the extent deducted in determining Consolidated Net Income for such
period; plus 
 (f) extraordinary losses and unusual or non-recurring charges (including restructuring charges and
reserves), severance, relocation costs and curtailments or modifications to pensions and post-retirement employee benefit plans; plus 

(g) decreases in unbilled service receivables; plus

for that portion of the period during which the condition described in the preceding proviso has occurred and is continuing). 

Notwithstanding the foregoing, clauses (1)(b) through (h) of this definition relating to amounts of a Restricted Subsidiary of a
Person will be added to Consolidated Net Income to compute Consolidated Adjusted EBITDA of such Person only to the extent (and in the same proportion) that the net income (loss) of such Restricted Subsidiary was included in calculating the
Consolidated Net Income of such Person and, to the extent the amounts set forth in clauses (1)(b) through (h) of this definition are in excess of those necessary to offset a net loss of such Restricted Subsidiary or if such Restricted
Subsidiary has net income for such period included in Consolidated Net Income, only if a corresponding amount would be permitted at the date of determination to be dividended to the Company by such Restricted Subsidiary without prior approval (that

Consolidated Interest Expense of any Excluded Project Subsidiary in the Development Stage) for such four fiscal quarters, provided, however, that: 

(1) if the Company or any Restricted Subsidiary: 

(a) has Incurred any Indebtedness since the beginning of such period that remains outstanding on such date of determination or
if the transaction giving rise to the need to calculate the Consolidated Coverage Ratio includes an Incurrence of Indebtedness, Consolidated Adjusted EBITDA and Consolidated Interest Expense for such period shall be calculated after giving effect on
a pro forma basis to such Indebtedness as if such Indebtedness had been Incurred on the first day of such period (except that in making such computation, the amount of 

  
 - 11 - 








 
Indebtedness under any revolving Debt Facility outstanding on the date of such calculation will be deemed to be (i) the average daily balance of such Indebtedness during such four fiscal
quarters or such shorter period for which such facility was outstanding or (ii) if such facility was created after the end of such four fiscal quarters, the average daily balance of such Indebtedness during the period from the date of creation
of such facility to the date of such calculation) and the discharge of any other Indebtedness repaid, repurchased, redeemed, retired, defeased or otherwise discharged with the proceeds of such new Indebtedness as if such discharge had occurred on
the first day of such period; or 
 (b) has repaid, repurchased, redeemed, retired, defeased or otherwise discharged any
Indebtedness since the beginning of the period that is no longer outstanding on such date of determination or if the transaction giving rise to the need to calculate the Consolidated Coverage Ratio includes a discharge of Indebtedness (in each case,
other than Indebtedness Incurred under any revolving Debt Facility unless such Indebtedness has been permanently repaid and the related commitment terminated and not replaced), Consolidated Adjusted EBITDA and Consolidated Interest Expense for such
period shall be calculated after giving effect on a pro forma basis to such discharge of such Indebtedness, including with the proceeds of such new Indebtedness, as if such discharge had occurred on the first day of such period; 

(2) if since the beginning of such period, the Company or any Restricted Subsidiary shall have made any Asset Disposition or disposed of or
discontinued (as defined under GAAP) any company, division, operating unit, segment, business, group of related assets or line of business or if the transaction giving rise to the need to calculate the Consolidated Coverage Ratio includes such a
transaction: 
 (a) the Consolidated Adjusted EBITDA for such period shall be reduced by an amount equal to the Consolidated
Adjusted EBITDA (if positive) directly attributable to the assets that are the subject of such disposition or discontinuation for such period or increased by an amount equal to the Consolidated Adjusted EBITDA (if negative) directly attributable
thereto for such period; and 
 (b) Consolidated Interest Expense for such period shall be reduced by an amount equal to the
Consolidated Interest Expense directly attributable to any Indebtedness of the Company or any Restricted Subsidiary repaid, repurchased, redeemed, retired, defeased or otherwise discharged (to the extent the related commitment is permanently
reduced) with respect to the Company and its continuing Restricted Subsidiaries in connection with such transaction for such period (or, if the Capital Stock of any Restricted Subsidiary is sold, the Consolidated Interest Expense for such period
directly attributable to the Indebtedness of such Restricted Subsidiary to the extent the Company and its continuing Restricted Subsidiaries are no longer liable for such Indebtedness after such sale);

 (3) if since the beginning of such period the Company or any Restricted Subsidiary (by merger or

acquisition of assets occurring in connection with a transaction causing a calculation to be made hereunder, which constitutes all or substantially all of a company, division, operating unit, segment, business, group of related assets or line of
business, Consolidated Adjusted EBITDA and Consolidated Interest Expense for such period will be calculated after giving pro forma effect thereto (including the Incurrence of any Indebtedness) as if such Investment or acquisition occurred on the
first day of such period; and 
 (4) if since the beginning of such period any Person (that subsequently became a Restricted Subsidiary or
was merged with or into the Company or any Restricted Subsidiary since the beginning of such period) shall have Incurred any Indebtedness or discharged any Indebtedness, made any disposition or any Investment or acquisition of assets that would have
required an adjustment pursuant to clause (1), (2) or (3) above if made by the Company or a Restricted Subsidiary during such period, Consolidated Adjusted EBITDA and Consolidated Interest Expense for such period shall be calculated after
giving pro forma effect thereto as if such transaction occurred on the first day of such period. 
 For purposes of this definition,
whenever pro forma effect is to be given to any calculation under this definition, the pro forma calculations will be determined in good faith by a responsible financial or accounting officer of the Company (including pro forma expense and cost
reductions calculated on a basis consistent with Regulation S-X under the Securities Act). If any Indebtedness bears a floating rate of interest and is being given pro forma effect, the interest expense on
such Indebtedness will be calculated as if the rate in effect on the date of determination had been the applicable rate for the entire period (taking into account any Interest Rate Agreement applicable to such Indebtedness if such Interest Rate
Agreement has a remaining term in excess of 12 months). If any Indebtedness that is being given pro forma effect bears an interest rate at the option of the Company, the interest rate shall be calculated by applying such optional rate chosen by the
Company. 
 “Consolidated Income Taxes” means, with respect to any Person for any period, taxes imposed upon such Person or

Indebtedness in respect of the relevant lease giving rise thereto, determined as if such lease were a capitalized lease in accordance with GAAP and the interest component of any deferred payment obligations; 

(2) amortization of debt discount (including the amortization of original issue discount resulting from the issuance of Indebtedness at less

which is one minus the then current combined federal, state, provincial and local statutory tax rate of such Person, expressed as a decimal, in each case, on a consolidated basis and in accordance with GAAP; and

expense (including any amounts described in clauses (1) through (9) above) relating to any Indebtedness of the Company or any Restricted Subsidiary described in the final paragraph of the definition of “Indebtedness.”

without duplication of clause (9) above, commissions, discounts, yield and other fees and charges Incurred in connection with any transaction pursuant to which the Company or its Restricted Subsidiaries may sell, convey or otherwise transfer or
grant a security interest in any accounts receivable or related assets shall be included in Consolidated Interest Expense.

ADDITIONAL COVENANTS 

SECTION 4.01. Reporting Covenant. Section 4.2 of the Original Indenture is hereby amended and restated with respect to the
Notes (but not with respect to any other series of Securities) as follows: 
 “(a) Notwithstanding that the Company may not be subject
to the reporting requirements of Section 13 or 15(d) of the Exchange Act or otherwise report on an annual and quarterly basis on forms provided for such annual and quarterly reporting pursuant to rules and regulations promulgated by the SEC, if
not filed electronically with the SEC through EDGAR (or any successor system), the Company shall file with the SEC (to the extent permitted by the Exchange Act), and make available to the Trustee and the Holders, without cost to any Holder, the
Annual Reports and the information, documents and other reports (or copies of such portions of any of the foregoing as the SEC may by rules and regulations prescribe) that are specified in Sections 13 and 15(d) of the Exchange Act with respect
to U.S. issuers within the time periods specified therein or in the relevant forms. The Company shall also comply with the other provisions of TIA Section 314(a). 

(b) In the event that the Company is not permitted to file such reports, documents and information with the SEC pursuant to the Exchange Act,
the Company shall nevertheless make available such Exchange Act reports, documents and information to the Trustee and the Holders as if the Company were subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act within the
time periods specified therein or in the relevant forms, which requirement may be satisfied by posting such reports, documents and information on its website within the time periods specified in this Section 4.01. 

(c) If the Company has designated any of its Subsidiaries as Unrestricted Subsidiaries and such Unrestricted Subsidiaries, either individually
or collectively, would otherwise have been a Significant Subsidiary, then the quarterly and annual financial information required by Section 4.01(b) shall include in the “Management’s discussion and analysis of financial condition and
results of operations” section, revenue, Consolidated Indebtedness, Consolidated Interest Expense, Consolidated Adjusted EBITDA and capital expenditures of the Company and its Restricted Subsidiaries separate from the financial condition and
results of operations of the Unrestricted Subsidiaries. 
 The Company shall be deemed to have furnished the reports to the Trustee and the
Holders if it has filed such reports with the SEC via the EDGAR filing system and such reports are publicly available. The Trustee shall have no obligation whatsoever to determine whether or not such information, documents, or reports have been
filed pursuant to the EDGAR system (or its successor) or the Company’s website. 

  
 - 44 - 








 Delivery of such reports, information and documents to the Trustee is for informational purposes
only and the Trustee’s receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Company’s compliance with any of its covenants hereunder
(as to which the Trustee is entitled to rely exclusively on Officers’ Certificates).” 
 SECTION 4.02. Covenant
Suspension. If, and for so long as, the Notes have an Investment Grade Rating from both of the Rating Agencies and no Default or Event of Default has occurred and is continuing, the Company and the Restricted Subsidiaries shall not be subject to
Sections 4.03, 4.04, 4.08, 4.09, 4.10 and 5.01(a)(4) (collectively, the “Suspended Covenants”). If at any time the credit rating for the Notes is downgraded from an Investment Grade Rating by any Rating Agency or if a Default or
Event of Default occurs and is continuing, then the Suspended Covenants shall thereafter be reinstated as if such covenants had never been suspended (the “Reinstatement Date”) and be applicable pursuant to the terms of the Indenture
(including in connection with performing any calculation or assessment to determine compliance with the terms of the Indenture), unless and until the Notes subsequently attain an Investment Grade Rating from both of the Rating Agencies and no
Default or Event of Default is in existence (in which event the Suspended Covenants shall no longer be in effect for such time that the Notes maintain an Investment Grade Rating from both of the Rating Agencies and no Default or Event of Default is
in existence). 
 The period of time between the date of suspension of the covenants and the Reinstatement Date is referred to as the
“Suspension Period.” No Default, Event of Default or breach of any kind shall be deemed to exist under the Indenture or the Notes with respect to the Suspended Covenants based on, and none of the Company or any of its Subsidiaries
shall bear any liability for, any actions taken or events occurring during the Suspension Period, regardless of whether such actions or events would have been permitted if the applicable Suspended Covenants remained in effect during the Suspension
Period. 
 On the Reinstatement Date, the amount of Excess Proceeds from Asset Dispositions shall be reset at zero. In addition, all
Indebtedness Incurred during the Suspension Period will be classified to have been Incurred pursuant to Section 4.03(a) or one of the clauses set forth in Section 4.03(b) (to the extent such Indebtedness would be permitted to be Incurred
thereunder as of the Reinstatement Date and after giving effect to Indebtedness Incurred prior to the Suspension Period and outstanding on the Reinstatement Date). To the extent such Indebtedness would not be so permitted to be Incurred pursuant to
Section 4.03(a) and 4.03(b) hereof, such Indebtedness will be deemed to have been outstanding on the Issue Date, so that it is classified under Section 4.03(b)(3) hereof. Calculations made after the Reinstatement Date of the amount
available to be made as Restricted Payments shall be made as though the covenants described under Section 4.04 hereof had been in effect since the Prior Issue Date and throughout the Suspension Period. Accordingly, Restricted Payments made
during the Suspension Period shall reduce the amount available to be made as Restricted Payments under Section 4.04(a). 

  
 - 45 - 








 During any period when the Suspended Covenants are suspended, neither the Board of Directors of
the Company nor Senior Management may designate any of the Company’s Subsidiaries as Unrestricted Subsidiaries or Excluded Project Subsidiaries. 

SECTION 4.03. Limitation on Indebtedness. (a) The Company shall not, and shall not permit any of its Restricted Subsidiaries to,
directly or indirectly, Incur any Indebtedness (including Acquired Indebtedness); provided, however, that the Company and its Restricted Subsidiaries may Incur Indebtedness if on the date thereof and after giving effect thereto on a
pro forma basis: 
 (1) the Consolidated Coverage Ratio for the Company and its Restricted Subsidiaries is at least 2.00 to 1.00;

 (2) in the case of Indebtedness Incurred by a Restricted Subsidiary, the Combined Leverage Ratio for the Company’s Restricted
Subsidiaries is no greater than 4.00 to 1.00; and 
 (3) no Default or Event of Default will have occurred or be continuing or
would occur as a consequence of Incurring the Indebtedness or entering into the transactions relating to such Incurrence. 
 (b)
Section 4.03(a) shall not prohibit the Incurrence of the following Indebtedness: 
 (1) Indebtedness of the Company or any

(d) For purposes of determining compliance with, and the outstanding principal amount of any particular Indebtedness Incurred pursuant to and

 (1) in the event that Indebtedness meets the criteria of more than one of the types of
Indebtedness described in Section 4.03(b), the Company, in its sole discretion, shall classify such item of Indebtedness on the date of Incurrence and may later reclassify such item of Indebtedness in any manner that complies with
Section 4.03(b) and only be required to include the amount and type of such Indebtedness in one of such clauses under Section 4.03(b), provided, however, that all Indebtedness outstanding on the Issue Date under the Senior Credit Facility
shall be deemed Incurred under Section 4.03(b)(1) and not Section 4.03(a) or Section 4.03(b)(3) and may not later be reclassified; 

(2) Guarantees of, or obligations in respect of letters of credit relating to, Indebtedness that is otherwise included in the
determination of a particular amount of Indebtedness shall not be included; 
 (3) if obligations in respect of letters of credit are
Incurred pursuant to a Debt Facility and are being treated as Incurred pursuant to Section 4.03(b)(1) and the letters of credit relate to other Indebtedness, then such other Indebtedness shall not be included; 

(4) the principal amount of any Disqualified Stock of the Company or a Restricted Subsidiary, or Preferred Stock of a Restricted
Subsidiary, will be equal to the greater of the maximum mandatory redemption or repurchase price (not including, in either case, any redemption or repurchase premium) or the liquidation preference thereof; 

  
 - 49 - 








 (5) Indebtedness permitted by this Section 4.03 need not be permitted solely by
reference to one provision permitting such Indebtedness but may be permitted in part by one such provision and in part by one or more other provisions of this Section 4.03 permitting such Indebtedness; 

(6) the principal amount of any Indebtedness outstanding in connection with a Qualified Receivables Transaction is the Receivables Transaction
Amount relating to such Qualified Receivables Transaction; and 
 (7) the amount of Indebtedness issued at a price that is less
than the principal amount thereof shall be equal to the amount of the liability in respect thereof determined in accordance with GAAP. 

Accrual of interest, accrual of dividends, the accretion of accreted value, the amortization of debt discount, the payment of interest in the
form of additional Indebtedness and the payment of dividends in the form of additional shares of Preferred Stock or Disqualified Stock shall not be deemed to be an Incurrence of Indebtedness for purposes of this Section 4.03. The amount of any
Indebtedness outstanding as of any date shall be (i) the accreted value thereof in the case of any Indebtedness issued with original issue discount or the aggregate principal amount outstanding in the case of Indebtedness issued with interest
payable in kind and (ii) the principal amount or liquidation preference thereof, together with any interest thereon that is more than 30 days past due, in the case of any other Indebtedness. 

(e) For purposes of determining compliance with any U.S. dollar-denominated restriction on the Incurrence of Indebtedness, the
U.S. dollar-equivalent principal amount of Indebtedness denominated in a foreign currency shall be calculated based on the relevant currency exchange rate in effect on the date such Indebtedness was Incurred, in the case of term Indebtedness,
or first committed, in the case of revolving credit Indebtedness; provided, however, that if such Indebtedness is Incurred to refinance other Indebtedness denominated in a foreign currency, and such refinancing would cause the applicable
U.S. dollar-denominated restriction to be exceeded if calculated at the relevant currency exchange rate in effect on the date of such refinancing, such U.S. dollar-denominated restriction shall be deemed not to have been exceeded so long
as the principal amount of such Refinancing Indebtedness does not exceed the principal amount of such Indebtedness being refinanced plus any premiums (including reasonable, as determined in good faith by the Company, tender premiums), defeasance
costs, accrued interest and fees and expenses in connection with such refinancing. Notwithstanding any other provision of this Section 4.03 the maximum amount of Indebtedness that the Company may Incur pursuant to Section 4.03 shall not be
deemed to be exceeded solely as a result of fluctuations in the exchange rate of currencies. The principal amount of any Indebtedness Incurred to refinance other Indebtedness, if Incurred in a different currency from the Indebtedness being
refinanced, shall be calculated based on the currency exchange rate applicable to the currencies in which such Refinancing Indebtedness is denominated that is in effect on the date of such refinancing.

 (f) Except as otherwise provided in this Section 4.03, the Company shall not permit any of
its Unrestricted Subsidiaries or its Excluded Project Subsidiaries to Incur any Indebtedness or issue any shares of Disqualified Stock, other than Non-Recourse Debt. 

(g) If at any date an Unrestricted Subsidiary becomes a Restricted Subsidiary, any Indebtedness of such Subsidiary shall be deemed to be
Incurred by a Restricted Subsidiary as of that date, and if such Indebtedness is not permitted to be Incurred as of that date under this Section 4.03, the Company shall be in Default of this Section 4.03).

(a) dividends or distributions payable solely in Capital Stock of the Company (other than Disqualified Stock); and

 (b) dividends or distributions by a Restricted Subsidiary, so long as, in the case of any dividend or distribution
payable on or in respect of any Capital Stock issued by a Restricted Subsidiary that is not a Wholly-Owned Subsidiary, the Company or the Restricted Subsidiary holding such Capital Stock receives at least its pro rata share of such dividend or
distribution; 
 (2) purchase, redeem, retire or otherwise acquire for value, including in connection with any merger or consolidation,
any Capital Stock of the Company or any direct or indirect parent of the Company held by Persons other than the Company or a Restricted Subsidiary (other than in exchange for Capital Stock of the Company (other than Disqualified Stock));

exception thereto) shall be referred to as a “Restricted Payment”),

financial statements are available provided, that the calculation of Consolidated Adjusted EBITDA and the adjustments to Consolidated Adjusted EBITDA for the purposes of this clause (i) shall exclude all amounts attributable to Excluded
Project Subsidiaries that are Excluded Project Subsidiaries as of the date of calculation, other than to include the aggregate amount of cash that has been distributed during such period or that is distributable as of such date by such Excluded
Project Subsidiary; plus

copy to the Trustee. 
 (b) Prior to repurchasing any Notes pursuant to a Change of Control Offer, the Company shall be required as a
condition to making the repurchase payment to either (1) obtain consent from the requisite holders of each issue of Indebtedness that may be violated by the repurchase to make the repurchase payment and waive any event of default caused by the
Change of Control or (2) repay all such Indebtedness that may be violated by making the repurchase payment, or offer to repay that Indebtedness and pay all holders of such Indebtedness that accept that offer, and obtain waivers of any event of
default arising under such Indebtedness.

(2) except in the case of a Permitted Asset Swap, at least 75% of the consideration from the Asset Disposition received by the Company or
Restricted Subsidiary is in the form of cash or Cash Equivalents; and 
 (3) all Net Available Cash from the Asset Disposition is
applied by the Company or Restricted Subsidiary within 365 days from the later of the date the Asset Disposition is completed or the Net Available Cash is received, as follows: 

(a) to permanently reduce obligations and related commitments under (x) the Senior Credit Facility or
(y) Secured Indebtedness of the Company (other than any Disqualified Stock or Subordinated Obligations) or Secured Indebtedness of a Restricted Subsidiary (other than any Disqualified Stock), in each case, other than Indebtedness owed to the
Company or an Affiliate of the Company; 
 (b) to permanently reduce obligations under other Indebtedness of the Company
(other than any Disqualified Stock or Subordinated Obligations) or Indebtedness of a Restricted Subsidiary (other than any Disqualified Stock), in each case other than Indebtedness owed to the Company or an Affiliate of the Company; provided
that, except in the case of a reduction in obligations of Indebtedness of a Restricted Subsidiary, the Company shall reduce Obligations under the Notes, (i) by redeeming Notes as provided in Section 3.01, (ii) through open market
purchases at prices that are at or above 100% of their principal amount or (iii) by making an offer to all Holders to purchase their Notes at 100% of their principal amount, plus accrued but unpaid interest to the date of purchase in accordance
with the procedures for an Asset Disposition Offer; or 
 (c) to invest in Additional Assets. 

Any Net Available Cash from Asset Dispositions that is not applied or invested as provided in Section 4.08(a) shall be deemed to constitute
“Excess Proceeds.” 
 For the purposes of clause (2) of this Section 4.08(a) and for no other purpose, the
following will be deemed to be cash: 
 (1) any liabilities (as shown on the Company’s or Restricted Subsidiary’s most recent
balance sheet) of the Company or any Restricted Subsidiary (other than liabilities that are by their terms subordinated to the Notes) that are assumed by the transferee of any such assets and from which the Company and all Restricted Subsidiaries
have been validly released by all creditors in writing; 

  
 - 58 - 








 (2) any securities, notes or other obligations received by the Company or any Restricted
Subsidiary from the transferee that are converted by the Company or such Restricted Subsidiary into cash (to the extent of the cash received) within 180 days following the closing of such Asset Disposition; and 

(3) any Designated Noncash Consideration received by the Company or any of its Restricted Subsidiaries in such Asset Disposition having an
aggregate Fair Market Value, taken together with all other Designated Noncash Consideration received pursuant to this clause (3) that is at that time outstanding, not to exceed the greater of (x) $100.0 million and (y) 2.5% of
Total Tangible Assets at the time of the receipt of such Designated Noncash Consideration (with the Fair Market Value of each item of Designated Noncash Consideration being measured at the time received without giving effect to subsequent changes in
value). 
 In the case of clause (c) of this Section 4.08(a)(3), a binding commitment to invest in Additional Assets shall be
treated as a permitted application of the Net Available Cash from the date of such commitment so long as the Company or such other Restricted Subsidiary enters into the commitment with the good faith expectation that the Net Available Cash will be
applied to satisfy the commitment within 270 days of such commitment (an “Acceptable Commitment”). In the event any Acceptable Commitment is later cancelled or terminated for any reason before the Net Available Cash is applied
in connection with the Acceptable Commitment, the Company or Restricted Subsidiary enters into another Acceptable Commitment (a “Second Commitment”) within 90 days of such cancellation or termination and with the good faith
expectation that the Net Available Cash will be applied within 180 days of such Second Commitment. If a Second Commitment is later cancelled or terminated for any reason before the Net Available Cash is applied, then the Net Available Cash
shall constitute Excess Proceeds. 
 Pending the final application of any such Net Available Cash in accordance with clause (a), (b) or
(c) of this Section 4.08(a)(3), the Company and its Restricted Subsidiaries may temporarily reduce Indebtedness (including under a revolving Senior Credit Facility) or invest the Net Available Cash in any manner not prohibited by the
Indenture. 
 (b) If the aggregate amount of Excess Proceeds exceeds $25.0 million on the 366th day after an Asset Disposition, the
Company shall be required to offer (an “Asset Disposition Offer”) to all Holders and, to the extent required by the terms of outstanding Pari Passu Indebtedness, to all holders of such Pari Passu Indebtedness, to purchase the
maximum aggregate principal amount of Notes and any such Pari Passu Indebtedness that may be purchased out of the Excess Proceeds, at an offer price in cash in an amount equal to 100% of their principal amount, plus accrued and unpaid interest, if
any, to the date of purchase (subject to the right of Holders of record on a Record Date to receive interest on the relevant Interest Payment Date), in accordance with the procedures set forth in the Indenture or the agreements governing the Pari
Passu Indebtedness, as applicable. To the extent that the aggregate amount of Notes and Pari Passu Indebtedness validly tendered and not properly withdrawn pursuant to an Asset Disposition Offer is less than the Excess Proceeds, the Company may use
any remaining Excess Proceeds for any purpose not prohibited by the Indenture. If the aggregate principal amount of Notes surrendered by Holders thereof and other Pari Passu Indebtedness surrendered by holders


  
 - 59 - 








 
or lenders, collectively, exceeds the amount of Excess Proceeds, tendered Notes and Pari Passu Indebtedness shall be repaid on a pro rata basis and selection of the Notes to be repurchased
shall be made by the Trustee on a pro rata basis, by lot or by such other method as the Trustee in its sole discretion shall deem to be fair and appropriate or in accordance with DTC procedures. Upon completion of such Asset Disposition
Offer, the amount of Excess Proceeds shall be reset at zero. 
 (c) If the Asset Disposition Purchase Date is on or after a Record Date and
on or before the related Interest Payment Date, any accrued and unpaid interest shall be paid to the Person in whose name a Note is registered at the close of business on such Record Date. 

(d) The Company shall comply, to the extent applicable, with the requirements of Rule 14e-1 under the Exchange Act and any other
securities laws or regulations in connection with the repurchase of Notes pursuant to an Asset Disposition Offer. 
 SECTION
4.09. Limitation on Restrictions on Distributions from Restricted Subsidiaries. (a) The Company shall not, and shall not permit any Restricted Subsidiary (other than Excluded Project Subsidiaries) to, directly or indirectly, create
or otherwise cause or permit to exist or become effective any consensual encumbrance or consensual restriction on the ability of any Restricted Subsidiary (other than Excluded Project Subsidiaries) to: 

(1) pay dividends or make any other distributions on its Capital Stock to the Company or any of its Restricted Subsidiaries (other than
Excluded Project Subsidiaries), or with respect to any other interest or participation in, or measured by, its profits, or pay any Indebtedness or other obligations owed to the Company or any Restricted Subsidiary (other than Excluded Project
Subsidiaries), it being understood that the priority of any Preferred Stock in receiving dividends or liquidating distributions prior to dividends or liquidating distributions being paid on Common Stock shall not be deemed a restriction on the
ability to make distributions on Capital Stock; 
 (2) make any loans or advances to the Company or any Restricted Subsidiary (other
than Excluded Project Subsidiaries), it being understood that the subordination of loans or advances made to the Company or any Restricted Subsidiary to other Indebtedness Incurred by the Company or any Restricted Subsidiary shall not be deemed a
restriction on the ability to make loans or advances; or 
 (3) sell, lease or transfer any of its property or assets to the Company or
any Restricted Subsidiary (other than any Excluded Project Subsidiary) (it being understood that such transfers shall not include any type of transfer described in clause (1) or (2) above). 

(b) Section 4.09(a) shall not prohibit encumbrances or restrictions existing under or by reason of: 

(1) contractual encumbrances or restrictions pursuant to the Senior Credit Facility and related documentation and other agreements or
instruments in effect at or entered into on the Issue Date; 

  
 - 60 - 








 (2) the Indenture and the Notes; 

(3) any agreement or other instrument of a Person acquired by the Company or any of its Restricted Subsidiaries in existence at the time of
such acquisition, which encumbrance or restriction is not applicable to any Person, or the properties or assets of any Person, other than the Person and its Subsidiaries, or the property or assets of the Person and its Subsidiaries, so acquired
(including after-acquired property); 
 (4) any amendment, restatement, modification, renewal, supplement, refunding, replacement or
refinancing of an agreement referred to in clauses (1), (2) or (3) of this Section 4.09(b) or this clause (4); provided, however, that such amendments, restatements, modifications, renewals, supplements, refundings,
replacements or refinancings are, in the good faith judgment of the Company, no more restrictive than the encumbrances and restrictions contained the agreements referred to in clauses (1), (2) or (3) of this Section 4.09(b) on the
Issue Date or the date such Restricted Subsidiary became a Restricted Subsidiary or was merged into a Restricted Subsidiary, whichever is applicable; 

(5) in the case of Section 4.09(a)(3), Liens permitted to be Incurred under Section 4.05 that limit the right of the debtor to
dispose of the assets securing such Indebtedness; 
 (6) purchase money obligations for property acquired in the ordinary course of business
and Capitalized Lease Obligations permitted under the Indenture, in each case, that impose encumbrances or restrictions of the nature described in Section 4.09(a)(3) on the property so acquired; 

(7) contracts for the sale of assets, including customary restrictions with respect to a Subsidiary of the Company pursuant to an agreement
that has been entered into for the sale or disposition of all or a portion of the Capital Stock or assets of such Subsidiary; 
 (8)
restrictions on cash or other deposits or net worth imposed by customers under contracts entered into in the ordinary course of business;

agreements entered into in the ordinary course of business;

 (11) encumbrances or
restrictions arising or existing by reason of applicable law or any applicable rule, regulation or order. 

  
 - 61 - 








 SECTION 4.10. Limitation on Affiliate Transactions. (a) The Company shall not,
and shall not permit any of its Restricted Subsidiaries to, directly or indirectly, enter into or conduct any transaction (including the purchase, sale, lease or exchange of any property or asset or the rendering of any service) with any Affiliate
of the Company (an “Affiliate Transaction”), if such Affiliate Transaction or series of related Affiliate Transactions involve aggregate consideration in excess of $5.0 million, unless: 

(1) the terms of such Affiliate Transaction are not materially less favorable to the Company or such Restricted Subsidiary (as reasonably
determined by the Company), than those that could have been obtained by the Company or such Restricted Subsidiary in a comparable transaction at the time of such transaction in dealings with a Person that is not an Affiliate; 

(2) in the event such Affiliate Transaction involves an aggregate consideration in excess of $50.0 million, the terms of such
transaction have been approved by a majority of the members of the Board of Directors of the Company and by a majority of the members of such Board of Directors having no personal stake in such transaction, if any, and such majority or majorities,
as the case may be, determines that such Affiliate Transaction satisfies the criteria in clause (1) of this Section 4.10(a); and 

(3) in the event such Affiliate Transaction involves an aggregate consideration in excess of $75.0 million, the Company has received
a written opinion from an Independent Financial Advisor that such Affiliate Transaction is fair from a financial point of view. 
 (b)
Section 4.10(a) shall not apply to:

(4) any Restricted Payment permitted to be made pursuant to Section 4.04 and the definition of “Permitted Investments”;

 (5) any issuance of securities or other payments, awards or grants in cash, securities or otherwise pursuant to, or as the funding of,
employment agreements and other compensation arrangements, options to purchase Capital Stock of the Company, restricted stock plans, long-term incentive plans, stock appreciation rights plans, participation plans or similar employee benefits plans

the Issue Date; provided that if such amendment, modification, supplement, extension or renewal involves an aggregate consideration in excess of $50.0 million, the terms thereof have been approved by the Board of Directors; 

(9) any agreement between any Person and an Affiliate of such Person existing at the time such Person is acquired by or merged into the
Company or a Restricted Subsidiary; provided that such agreement was not entered into contemplation of such acquisition or merger, and any amendment thereto (so long as any such agreement as so amended is not disadvantageous to the Holders,
when taken as a whole, as compared to the applicable agreement as in effect on the date of such acquisition or merger, provided that if such amendment involves an aggregate consideration in excess of $50.0 million, the terms thereof have been
approved by the Board of Directors); 
 (10) transactions with customers, clients, suppliers, joint venture partners or purchasers or sellers
of goods or services, in each case in the ordinary course of the business of the Company and its Restricted Subsidiaries and otherwise in compliance with the terms of the Indenture; provided that in the reasonable determination of the Board
of Directors or Senior Management of the Company, such transactions are on terms that are no less favorable to the Company or the relevant Restricted Subsidiary than those that could have been obtained at the time of such transactions in a

of the Company or such direct or indirect parent company, as the case may be, on any matter involving such other Person. 
 SECTION
4.11. Payments for Consent. The Company shall not, and shall not permit any of its Subsidiaries to, directly or indirectly, pay or cause to be paid any consideration to or for the benefit of any Holder for or as an inducement to any
consent, waiver or amendment of any of the terms or provisions of the Indenture or the Notes unless such consideration is offered to be paid and is paid to all Holders that consent, waive or agree to amend in the time frame set forth in the
solicitation documents relating to such consent, waiver or amendment.

admission by the Company or any Significant Subsidiary in writing of its inability to pay its debts generally as they become due, or the taking of corporate action by the Company or any Significant Subsidiary in furtherance of any such action. 

Notwithstanding the foregoing, a default under Section 6.01(4) and (5) shall not constitute an Event of Default until the Trustee or
the Holders of 25% in principal amount of the then outstanding Notes notify the Company in writing of the default and the Company does not cure such default within the time specified in Section 6.01(4) and (5) after receipt of such written
notice. 
 SECTION 6.02. Acceleration of Maturity; Rescission and Annulment. Solely with respect to the Notes, Section 6.2
of the Original Indenture shall be amended and restated in its entirety by inserting the following in lieu thereof: 
 “If an Event of
Default (other than an Event of Default described in Section 6.01(8) or (9) hereof) occurs and is continuing, the Trustee by written notice to the Company, specifying the Event of Default, or the Holders of at least 25% in principal amount
of the then outstanding Notes by written notice to the Company and the Trustee, may, and the Trustee at the written request of such Holders shall, declare the principal of, premium, if any, and accrued and unpaid interest, if any, on all the Notes
to be due and payable. Upon such a declaration, such principal, premium, if any, and accrued and unpaid interest, if any, will be due and payable immediately. In the event of a declaration of acceleration of the Notes because an Event of Default
described in Section 6.01(6) has occurred and is continuing, the declaration of acceleration of the Notes shall be automatically annulled if the default triggering such Event of Default pursuant to Section 6.01(6) shall be remedied or
cured by the Company or a Restricted Subsidiary or waived by the holders of the relevant Indebtedness within 20 days after the declaration of acceleration with respect thereto and if (1) the annulment of the acceleration of the Notes would
not conflict with any judgment or decree of a court of competent jurisdiction and (2) all existing Events of Default, except nonpayment of principal, premium, if any, or interest on the Notes that became due solely because of the acceleration
of the Notes, have been cured or waived. If an Event of Default described in Section 6.01(8) or (9) occurs and is continuing, the principal of, premium, if any, and accrued and unpaid interest, if any, on all the Notes will


  
 - 68 - 








 
become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holders. The Holders of a majority in principal amount of the outstanding Notes
may waive all past defaults (except with respect to nonpayment of principal, premium or interest) and rescind any such acceleration with respect to the Notes and its consequences if (1) rescission would not conflict with any judgment or decree
of a court of competent jurisdiction and (2) all existing Events of Default, other than the nonpayment of the principal of, premium, if any, and interest on the Notes that have become due solely by such declaration of acceleration, have been
cured or waived.” 
 SECTION 6.03. Limitation on Suits. Solely with respect to the Notes, Section 6.7 of the Original
Indenture shall be amended and restated in its entirety by inserting the following in lieu thereof: 
 “Except to enforce the right to
receive payment of principal, premium, if any, or interest when due, no Holder may pursue any remedy with respect to the Indenture or the Notes unless: 

(1) such Holder has previously given the Trustee written notice that an Event of Default is continuing; 

(2) Holders of at least 25% in principal amount of the then outstanding Notes have requested the Trustee to pursue the remedy; 

(3) such Holders have offered the Trustee security or indemnity satisfactory to the Trustee against any loss, liability or expense; 

(4) the Trustee has not complied with such request within 60 days after the receipt of the request and the offer of security or
indemnity; and 
 (5) the Holders of a majority in principal amount of the then outstanding Notes have not given the Trustee a direction
that, in the opinion of the Trustee, is inconsistent with such request within such 60-day period. 
 Notwithstanding any other provision of
this Fourth Supplemental Indenture and any provision of any Notes, the right of any Holder to receive payment of the principal of and accrued interest on Notes, on or after the respective due dates expressed in such Notes or in the event of
redemption or repurchase, or to institute suit for the enforcement of any such payment on or after such respective dates against the Company shall not be impaired or affected without the consent of such Holder.”

amended and restated in its entirety by inserting the following in lieu thereof:

end of each fiscal year ending after the Issue Date, a certificate indicating whether the signers thereof, one of whom shall be the principal executive officer, principal financial officer or principal accounting officer, know of any Default that
occurred during the previous year. The Company shall also deliver to the Trustee, within 10 Business Days after the occurrence thereof, written notice of any events which would constitute a Default, their status and what action the Company is taking

Notwithstanding the satisfaction and discharge of this Indenture, the obligations of the Company to the Trustee under Section 7.7 of the
Original Indenture, and, if money shall have been deposited with the Trustee pursuant to clause (2)(a) of this Section 8.01, the provisions of Sections 2.4, 2.7, 2.8 and 9.2 of the Indenture, this Section 8.01 and Section 8.03 of

 - 71 - 








 SECTION 8.04. Conditions to Defeasance. The Company may exercise its option under
Section 8.02 or 8.03 if: 
 (1) the Company irrevocably deposits with the Trustee, in trust, for the benefit of the Holders, cash in
U.S. dollars, Government Securities, or a combination thereof, in amounts as will be sufficient, in the opinion of a nationally recognized firm of independent public accountants without consideration of any reinvestment of interest, to pay the
principal of, and premium, if any, and interest due on the outstanding Notes on the Stated Maturity or on the applicable redemption date, as the case may be, and the Company specifies whether the Notes are being defeased to maturity or to a
particular redemption date; 
 (2) in the case of the exercise of the option under Section 8.02, the Company has delivered to the
Trustee an Opinion of Counsel reasonably acceptable to the Trustee confirming that (a) the Company has received from, or there has been published by, the Internal Revenue Service a ruling, or (b) since the Issue Date, there has been a
change in the applicable U.S. federal income tax law, in either case to the effect that, and based thereon such Opinion of Counsel will confirm that, subject to customary assumptions and exclusions, the Holders will not recognize income, gain
or loss for U.S. federal income tax purposes as a result of such legal defeasance and will be subject to U.S. federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such legal
defeasance had not occurred; 
 (3) in the case of the exercise of the option under Section 8.03, the Company has delivered to the
Trustee an Opinion of Counsel reasonably acceptable to the Trustee confirming that, subject to customary assumptions and exclusions, the Holders will not recognize income, gain or loss for U.S. federal income tax purposes as a result of such
covenant defeasance and will be subject to U.S. federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such covenant defeasance had not occurred; 

(4) such exercise will not result in a breach or violation of, or constitute a default under any material agreement or instrument (other than
this Fourth Supplemental Indenture) to which the Company or any of its Restricted Subsidiaries is a party or by which the Company or any of its Restricted Subsidiaries is bound; 

(5) no Default or Event of Default has occurred and is continuing on the date of such deposit (other than a Default or an Event of Default
resulting from the borrowing of funds to be applied to make such deposit and any similar and simultaneous deposit relating to other Indebtedness and, in each case, the granting of Liens in connection therewith) or insofar as Events of Default
resulting from the borrowing of funds or insolvency events are concerned, at any time in the period ending on the 91st day after the date of deposit; 

  
 - 72 - 








 (6) the Company shall have delivered to the Trustee an Opinion of Counsel to the effect that, as
of the date of such opinion and subject to customary assumptions and exclusions, including, that no intervening bankruptcy of the Company between the date of deposit and the 91st day following the deposit and assuming that no Holder is an
“insider” of the Company under applicable bankruptcy law, after the 91st day following the deposit, the trust funds will not be subject to the effect of any applicable bankruptcy, insolvency, reorganization of similar laws affecting
creditors’ rights generally; 
 (7) the Company has delivered to the Trustee an Officers’ Certificate stating that the deposit was
not made by the Company with the intent of defeating, hindering, delaying or defrauding creditors of the Company or others; 
 (8) the
Company has delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel (which Opinion of Counsel may be subject to customary assumptions and exclusions), each stating that all conditions precedent to the exercise of the option
under Section 8.02 or 8.03, as the case may be, have been complied with; and 
 (9) the Company has delivered irrevocable written
instructions to the Trustee to apply the deposited money toward the payment of the Notes at maturity or the redemption date, as the case may be (which instructions may be contained in the Officers’ Certificate referred to in clause (8)
above).”

this Fourth Supplemental Indenture, including, without limitation to facilitate the issuance and administration of the Notes or, if Incurred in compliance with this Fourth Supplemental Indenture, Additional Notes; provided, however, that
(A) compliance with this Fourth Supplemental Indenture as so amended would not result in Notes being transferred in violation of the Securities Act or any applicable securities law and (B) such amendment does not materially and adversely

 SECTION 9.02. With Consent of Noteholders. Solely with respect to the
Notes, Section 10.2 of the Original Indenture shall be amended and restated in its entirety by inserting the following in lieu thereof:

(1) reduce the principal amount of Notes whose Holders must consent to an amendment, supplement or waiver; 

(2) reduce the stated rate of interest or extend the stated time for payment of interest on any Note;

 (8)
make any change in the amendment or waiver provisions which require each affected Holder’s consent. 
 It shall not be necessary for
the consent of the Noteholders under the Indenture to approve the particular form of any proposed amendment, supplement or waiver. It shall be sufficient if such consent approves the substance of the proposed amendment or supplement. A consent to
any amendment, supplement or waiver under the Indenture by any Holder given in connection with a tender of such Holder’s Notes will not be rendered invalid by such tender. After an amendment, supplement or waiver under the Indenture becomes
effective, the Company shall be required to give to the Holders a notice briefly describing such amendment, supplement or waiver. Notwithstanding the foregoing, the failure to give such notice to all the Holders, or any defect in the notice shall
not impair or affect the validity of the amendment, supplement or waiver. 
 Any Notes held by the Company or an Affiliate of the Company
shall be disregarded (from both the numerator and the denominator) for purposes of determining whether the holders of the requisite aggregate principal amount of the outstanding Notes have consented to or voted for a modification, amendment or
