Certain Amounts. Whenever pursuant to this Note the Borrower is required to pay an amount in excess of the outstanding principal amount (or the portion thereof required to be paid at that time) plus accrued and unpaid interest, the Borrower and the Holder agree that the actual damages to the Holder from the receipt of cash payment on this Note may be difficult to determine and the amount to be so paid by the Borrower represents stipulated damages and not a penalty and is intended to compensate the Holder in part for loss of the opportunity to convert this Note and to earn a return from the sale of shares of Common Stock acquired upon conversion of this Note at a price in excess of the price paid for such shares pursuant to this Note. The Borrower and the Holder hereby agree that such amount of stipulated damages is not plainly disproportionate to the possible loss to the Holder from the receipt of a cash payment without the opportunity to convert this Note into shares of Common Stock.

Minimum Amounts. (A) in the case of an assignment of the entire remaining amount of the assigning Lender’s Revolving Credit Commitments and the Loans at the time owing to it (in each case with respect to the Revolving Facility) or contemporaneous assignments to related Approved Funds that equal at least the amount specified in paragraph (b)(i)(B) of this Section in the aggregate or in the case of an assignment to a Lender, an Affiliate of a Lender or an Approved Fund, no minimum amount need be assigned; and

Proportionate Amounts. Each partial assignment shall be made as an assignment of a proportionate part of all the assigning Lender’s rights and obligations under this Agreement with respect to the Loan or the Revolving Credit Commitment assigned.

no minimum amount need be assigned in the case of # an assignment of the entire remaining amount of the assigning Lender’s Commitment under any Facility and the Loans at the time owing to it under such Facility and # an assignment by a Lender to any other ​, Affiliates and Approved Funds; and

Minimum Amounts. Each Borrowing under this Section shall be in an aggregate principal amount of $5,000,000 or any larger multiple of $1,000,000 (except that any such Borrowing may be in the aggregate amount available within the limitations set forth above) and shall be made from the several ​ ratably in proportion to their respective Commitments.

For the purpose of performing the calculations in this Clause 3, amounts not in US$ shall be converted into US$ on the date of such calculation using the Exchange Rate.

If Seller in good faith disagrees with Purchaser’s Estimated Specified Account Net Commissions and Fees, Seller may, within 30 days after receipt of such statement (the “Additional Payment Objection Period”), deliver to Purchaser a notice disagreeing therewith and setting forth Seller’s objections (the “Additional Payment Objection Notice”). The Additional Payment Objection Notice shall specify in reasonable detail those items or amounts as to which Seller disagrees, the basis of such disagreement and, if the disagreement relates to the calculation of amounts, Seller’s calculation of such amounts. If the Additional Payment Objection Notice is not timely received by Purchaser within the Additional Payment Objection Period, Seller shall be deemed to agree in all respects with the applicable Estimated Specified Account Net Commissions and Fees as prepared by Purchaser, and such calculation shall be final and binding on the Parties.

“Net Working Capital” means the net working capital of Seller determined in accordance with the policies, procedures and values set forth on [Schedule C] (as consistently applied in accordance with the past practices of Seller), which, for the avoidance of doubt, is an illustrative calculation of Net Working Capital as of April 30, 2017; provided, however, that in no event shall the calculation of Net Working Capital include any amounts relating to (a) any amounts or items included in the calculation of the Net Indebtedness Amount or the Seller Transaction Expenses, (b) any undrawn letters of credit, surety bonds and other credit support or the mark-to-market derivative assets or liabilities with respect to the Commodity Hedges, or (c) any Tax assets or Tax liabilities.

Severability; Maximum Payment Amounts. If any provision of this Agreement is prohibited by law or otherwise determined to be invalid or unenforceable by a court of competent jurisdiction, the provision that would otherwise be prohibited, invalid or unenforceable shall be deemed amended to apply to the broadest extent that it would be valid and enforceable, and the invalidity or unenforceability of such provision shall not affect the validity of the remaining provisions of this Agreement so long as this Agreement as so modified continues to express, without material change, the original intentions of the parties as to the subject matter hereof and the prohibited nature, invalidity or unenforceability of the provision(s) in question does not substantially impair the respective expectations or reciprocal obligations of the parties or the practical realization of the benefits that would otherwise be conferred upon the parties. The parties will endeavor in good faith negotiations to replace the prohibited, invalid or unenforceable provision(s) with a valid provision(s), the effect of which comes as close as possible to that of the prohibited, invalid or unenforceable provision(s). Notwithstanding anything to the contrary contained in this Agreement or any other Transaction Document (and without implication that the following is required or applicable), it is the intention of the parties that in no event shall amounts and value paid by the Company and/or any of its Subsidiaries (as the case may be), or payable to or received by any of the Buyers, under the Transaction Documents (including without limitation, any amounts that would be characterized as “interest” under applicable law) exceed amounts permitted under any applicable law. Accordingly, if any obligation to pay, payment made to any Buyer, or collection by any Buyer pursuant the Transaction Documents is finally judicially determined to be contrary to any such applicable law, such obligation to pay, payment or collection shall be deemed to have been made by mutual mistake of such Buyer, the Company and its Subsidiaries and such amount shall be deemed to have been adjusted with retroactive effect to the maximum amount or rate of interest, as the case may be, as would not be so prohibited by the applicable law. Such adjustment shall be effected, to the extent necessary, by reducing or refunding, at the option of such Buyer, the amount of interest or any other amounts which would constitute unlawful amounts required to be paid or actually paid to such Buyer under the Transaction Documents. For greater certainty, to the extent that any interest, charges, fees, expenses or other amounts required to be paid to or received by such Buyer under any of the Transaction Documents or related thereto are held to be within the meaning of “interest” or another applicable term to otherwise be violative of applicable law, such amounts shall be pro-rated over the period of time to which they relate.

Letter of Credit Amounts. Unless otherwise specified herein, the amount of a Letter of Credit at any time shall be deemed to be the stated amount of such Letter of Credit in effect at such time; provided, however, that with respect to any Letter of Credit that, by its terms or the terms of any Issuer Document related thereto, provides for one or more automatic increases in the stated amount thereof, the amount of such Letter of Credit shall be deemed to be the maximum stated amount of such Letter of Credit after giving effect to all such increases, whether or not such maximum stated amount is in effect at such time.
