Certain Definitions. Capitalized terms used, but not otherwise defined, in this Agreement will have the meanings given to such terms in the Company’s 2016 Equity and Incentive Compensation Plan (the “Plan”). As used in this Agreement:

Certain Exceptions. Notwithstanding anything to the contrary set forth above, if, with respect to any particular transaction(s), it is impossible or impracticable under the circumstances to comply with the procedures set forth in subsections [(a) and (b) of this Section 5.7] (including the time periods specified therein), the Parties will cooperate to find a mutually agreeable alternative that will achieve substantially similar economic results from the point of view of the Paying Party or the Other Party, as the case may be; provided, however, that if a Receiving Party cannot comply with the procedures set forth in subsection # of this Section 5.7 because it does not become aware of a Receipt on behalf of the Other Party in time, such Receiving Party shall remit such Receipt (without interest thereon) to the Other Party within 24 hours after it becomes aware of such Receipt.

Certain Definitions. Unless the context otherwise indicates, the following words used herein shall have the following meanings whenever used in this instrument:

Certain Pledges. Any Lender may at any time pledge or assign a security interest in all or any portion of its rights under this Agreement to secure obligations of such Lender, including any pledge or assignment to secure obligations to a Federal Reserve Bank; provided that no such pledge or assignment shall release such Lender from any of its obligations hereunder or substitute any such pledgee or assignee for such Lender as a party hereto.

No Defaulting Lender shall be entitled to receive any fee payable under [Section 2.4(c)] or for any period during which that Lender is a Defaulting Lender (and Borrower shall not be required to pay any such fee that otherwise would have been required to have been paid to that Defaulting Lender).

Certain Events. The Company will not be required to adjust the Strike Price or the Warrant Entitlement except pursuant to [Section 5(e)(i)]. Without limiting the foregoing, the Company will not be required to adjust the Strike Price or the Warrant Entitlement on account of:

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 plus Default Interest on such 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.

Certain Fees. Except as set forth in the Prospectus Supplement, no brokerage or finder’s fees or commissions are or will be payable by the Company or any Subsidiary to any broker, financial advisor or consultant, finder, placement agent, investment banker, bank or other Person with respect to the transactions contemplated by the Transaction Documents. The Purchasers shall have no obligation with respect to any fees or with respect to any claims made by or on behalf of other Persons for fees of a type contemplated in this Section that may be due in connection with the transactions contemplated by the Transaction Documents.

Certain Events. If any event occurs of the type contemplated by the provisions of this Section 8 but not expressly provided for by such provisions (including, without limitation, the granting of stock appreciation rights, phantom stock rights or other rights with equity features), then the Company’s Board of Directors will make an appropriate adjustment in the Warrant Exercise Price and the number of shares of Common Stock obtainable upon exercise of this Warrant so as to protect the rights of the holders of the Warrants; provided, except as set forth in section 8(c),that no such adjustment pursuant to this Section 8(e) will increase the Warrant Exercise Price or decrease the number of shares of Common Stock obtainable as otherwise determined pursuant to this Section 8.

Certain Terms. The words such as “herein,” “hereinafter,” “hereof,” and “hereunder” refer to this Agreement (including the Exhibits and Schedules to this Agreement) as a whole and not merely to a subdivision in which such words appear unless the context otherwise requires. The word “including” or any variation thereof means “including, without limitation” and does not limit any general statement that it follows to the specific or similar items or matters immediately following it. The words “to the extent” when used in reference to a liability or other matter, means that the liability or other matter referred to is included in part or excluded in part, with the portion included or excluded determined based on the portion of such liability or other matter exclusively related to the subject or period. The word “or” shall be disjunctive but not exclusive. A reference to any Party or to any party to any other agreement or document shall include such party’s successors and permitted assigns. A reference to any legislation or to any provision of any legislation shall include any amendment to, and any modification or reenactment thereof, any legislative provision substituted therefor and all regulations and statutory instruments issued thereunder or pursuant thereto (provided, that for purposes of any representations and warranties contained in this Agreement that are made as of a specific date, references to any statute shall be deemed to refer to such statute and any rules or regulations promulgated thereunder as amended through such specific date). The phrase “ordinary course of business” refers to the ordinary course of business of the Acquired Companies and not of Sellers and their Affiliates generally. References to “$” shall mean U.S. dollars and references to “written” or “in writing” include in electronic form. Any reference to “days” shall mean calendar days unless Business Days are expressly specified. Any reference to information “made available” or “provided” to Purchaser by Sellers or the Acquired Companies means that such information has been provided to Purchaser, its counsel or other Representatives through access to the “Project Nickel” online data room maintained by Sellers and hosted by Donnelly Financial Solutions in connection with the transactions contemplated by this Agreement, with such information and access provided at least three (3) Business Days prior to the date hereof.
