and restating the following definitions:

operating expense reductions and cost-savings of the Borrower and its Subsidiaries that are reasonably 

  
 2 

 
identifiable, factually supportable and projected by the Borrower in good faith to be realized following the Closing Date (as defined in the Wells Credit Agreement) as a result of restructurings,
reorganizations, divestitures, cost savings initiatives, production rationalizations and other similar initiatives, in each case to the extent not prohibited by this Agreement (collectively, “Initiatives”) (calculated on a pro forma
basis as if such synergies, operating expense reductions and cost-savings had been realized on the first day of such period, and net of the amount of actual benefits realized during such period from such Initiatives to the extent already included in
Consolidated Net Income for such period); provided that (i) no synergies, operating expense reductions or cost-savings shall be added to Consolidated EBITDA pursuant to clause (e) thereof to the extent duplicative of any expenses or
charges otherwise added to (or excluded from) Consolidated EBITDA, whether through a pro forma adjustment or otherwise, for such period and (ii) projected amounts (and not yet realized) (x) may be added (the date on which such amounts are
added, the “Initiative Commencement Date”) once actions in respect of such Initiative have been taken or are expected to be taken (in the good faith determination of the Borrower) within 12 months and (y) may no longer be added
back in calculating Consolidated EBITDA pursuant to clause (e) thereof to the extent occurring more than six full fiscal quarters after the Initiative Commencement Date. 

“Consolidated EBITDA” means, for any period, Consolidated Net Income for such period (adjusted to exclude all
extraordinary or unusual items and any gains or losses on sales of assets outside the ordinary course of business) plus, without duplication and (except with respect to synergies included in Consolidated Cost Savings) to the extent deducted
in calculating such Consolidated Net Income for such period, the sum of (a) income tax expense, (b) interest expense, amortization or writeoff of debt discount with respect to Indebtedness (including the Advances), (c) depreciation and
amortization expense, (d) amortization of intangibles (including, but not limited to, goodwill) and organization costs, (e) Consolidated Cost Savings; provided that with respect to any period, the aggregate amount added back in the
calculation of Consolidated EBITDA for such period pursuant to this clause (e) and clause (f) below shall not exceed (x) for any period ended on or prior to December 31, 2018, 20% of Consolidated EBITDA and (y) otherwise,
15% of Consolidated EBITDA (calculated prior to giving effect to any add-backs pursuant to this clause (e) and clause (f) below); provided further that for any period ended after
December 31, 2019, no such Consolidated Cost Savings pursuant to this clause (e) may be added back, (f) costs and expenses incurred in connection with the implementation of Initiatives; provided that with respect to any period,
the aggregate amount added back in the calculation of Consolidated EBITDA for such period pursuant to this clause (f) and clause (e) above shall not exceed (x) for any period ended on or prior to December 31, 2018, 20% of
Consolidated EBITDA and (y) otherwise, 15% of Consolidated EBITDA (calculated prior to giving effect to any add-backs pursuant to this clause (f) and clause (e) above); provided
further that for any period ended after December 31, 2019, no such costs or expenses pursuant to this clause (f) may be added back, (g) all payments triggered in respect of the Borrower’s
non-qualified deferred compensation and post-retirement benefit plans in connection with the Transactions during such period and (h) any other non-cash charges,
minus, (i) any cash payments made during such period in respect of items described in clause (h) above subsequent to the fiscal quarter in which the relevant non-cash charge was reflected as a
charge in the statement of 

  
 3 

 
Consolidated Net Income and (ii) to the extent included in calculating such Consolidated Net Income for such period, any non-cash income (other than
amounts accrued in the ordinary course of business under accrual-based revenue recognition procedures in accordance with GAAP). For the purposes of calculating Consolidated EBITDA for any Reference Period pursuant to any determination of the
Consolidated Leverage Ratio, if during such Reference Period the Company or any Subsidiary shall have made a Material Acquisition or a Material Disposition, Consolidated EBITDA for such Reference Period shall be calculated after giving pro forma
effect thereto as if such Material Acquisition or Material Disposition, as applicable, occurred on the first day of such Reference Period. 

“Consolidated Total Debt” means, at any date, the aggregate principal amount of all Indebtedness of the Borrower and
its Subsidiaries at such date, determined on a consolidated basis in accordance with GAAP. 
 “LIBOR” shall mean,
for any Interest Period, the greater of (A) zero percent per annum and (B) the interest rate per annum determined by the Administrative Agent by dividing (the resulting quotient rounded upwards, if necessary, to the nearest 1/100th of 1%
per annum) (i) the rate which appears on the Bloomberg Page BBAM1 (or on such other substitute Bloomberg page that displays rates at which US dollar deposits are offered by leading banks in the London interbank deposit market), or the rate
which is quoted by another source selected by the Administrative Agent which has been approved by the British Bankers’ Association as an authorized information vendor for the purpose of displaying rates at which US dollar deposits are offered
by leading banks in the London interbank deposit market (an “Alternate Source”), at approximately 11:00 a.m., London time, on the Interest Rate Determination Date as the London interbank offered rate for U.S. Dollars for an amount
comparable to the Outstanding Principal Amount of the Bonds and having a borrowing date and a maturity comparable to such Interest Period (or if there shall at any time, for any reason, no longer exist a Bloomberg Page BBAM1 (or any substitute page)
or any Alternate Source, a comparable replacement rate determined by the Administrative Agent at such time (which determination shall be conclusive absent manifest error)), by (ii) a number equal to 1.00 minus the LIBOR Reserve Percentage.
LIBOR may also be expressed by the following formula: 
  

					
	LIBOR =	  	 Bloomberg Page BBAM1
	  	
		  	1.00 - LIBOR Reserve Percentage	  	

 “Loan Documents” means this Agreement, the Administrative Agent’s Letter, the
Indentures, the Loan Agreements, the Bond Notes, the Bonds, the Tax Regulatory Agreements and any other instruments, certificates or documents delivered in connection herewith or in connection with the issuance of the Bonds. 

“Wells Credit Agreement” means that Credit Agreement dated as of June 23, 2015, as may be supplemented and amended from time to
time, among the Borrower, Olin Canada ULC, the lenders and issuers of letters of credit that are party to such Wells Credit Agreement or become party to such Credit Agreement pursuant to the terms thereof and Wells Fargo Bank, National Association,
