This First Amendment to First Amended and Restated Credit Agreement, is dated the 23rd  day of February, 2017 (this "Amendment"), by and among Calgon Carbon Corporation, a Delaware corporation ("Calgon Carbon"), each of the Guarantors (as defined herein), each of the Lenders (as defined herein) and PNC Bank, National Association ("PNC"), as administrative agent for the Lenders (PNC, in such capacity, the "Administrative Agent").

W I T N E S S E T H:

WHEREAS, Calgon Carbon, the other Borrowers from time to time party thereto (together with Calgon Carbon, collectively the "Borrowers" and each a "Borrower"), the Guarantors from time to time party thereto (the "Guarantors"), PNC and various other financial institutions party thereto (PNC and such other financial institutions are each, a "Lender" and collectively, the "Lenders") and the Administrative Agent entered into that certain First Amended and Restated Credit Agreement, dated as of October 4, 2016 (as amended, modified, supplemented or restated from time to time, the "Credit Agreement"); and

WHEREAS, the Loan Parties desire to amend certain provisions of the Credit Agreement and the Administrative Agent and the Lenders desire to permit such amendments pursuant to the terms and conditions set forth herein.

NOW, THEREFORE, in consideration of the premises contained herein and other valuable consideration, the receipt and sufficiency of which are hereby acknowledged, and intending to be legally bound hereby, the parties hereto agree as follows:

1.            All capitalized terms used herein which are defined in the Credit Agreement shall have the same meaning herein as in the Credit Agreement unless the context clearly indicates otherwise.

2.            The definition of "EBITDA" set forth in Section 1.1 [Definitions] of the Credit Agreement is hereby amended and restated in its entirety as follows:

EBITDA shall mean, for any period of determination, Net Income for such period plus (a) without duplication and to the extent deducted in determining Net Income for such period, the sum of (i) Interest Expense, (ii) income tax expense, net of tax refunds, (iii) all amounts attributable to depreciation and amortization expense and (iv) any non-cash charges (excluding non-cash charges that are expected to become cash charges in a future period or that are reserves for future cash charges and any non-cash charge that relates to the write-down or write-off of inventory) plus non-recurring costs and expenses in connection with Permitted Acquisitions, including the CECA Acquisition, in an amount not to exceed $17,500,000 in the aggregate for all Permitted Acquisitions (including the CECA Acquisition), minus (b) without duplication and to the extent included in Net Income, (i) any non-cash gains (excluding non-cash gains that represent an accrual or reserve for a future or potential cash payment), all calculated for the Parent on a Consolidated Basis in accordance with GAAP.  For purposes of this definition, with respect to a business acquired by the Loan Parties pursuant to a Permitted Acquisition, EBITDA as reported in the Leverage Ratio shall be calculated on a pro forma basis, using (i) historical numbers, in accordance with GAAP as if the Permitted Acquisition had been consummated at the beginning of such period and set forth in a certificate delivered by an Authorized Officer of the Borrowing Agent to the Administrative Agent (which certificate shall also set forth in reasonable detail the calculation of such financial effects); provided that, for purposes of calculating EBITDA as reported in the pro forma Leverage Ratio with respect to the CECA Acquisition, EBITDA shall be calculated using historical numbers in accordance with International Financial Reporting Standards (IFRS).  Additionally, for purposes of this definition, with respect to a business or assets disposed of by the Loan Parties pursuant to Section 8.2.7 [Disposition of Assets or Subsidiaries] hereof, EBITDA as reported in the maximum Leverage Ratio shall be calculated as if such disposition had been consummated at the beginning of such period.  In addition, EBITDA shall be adjusted to the extent that the computation of EBITDA includes a gain or loss with respect to a Swap Agreement as follows: EBITDA shall be (1) increased by any non-cash items of loss arising from such Swap Agreement, in each case, net of any actual cash payments related to the items giving rise to the loss and (2) decreased by any non-cash items of gain arising from such Swap Agreement, in each case, net of any actual cash payments related to items giving rise to the gain.

3.            The definition of "Optional Currency" set forth in Section 1.1 [Definitions] of the Credit Agreement is hereby amended and restated in its entirety as follows:

Optional Currency shall mean any of the following currencies (i) British Pounds Sterling, (ii) Japanese Yen, (iii) Euros, (iv) Canadian Dollars, (v) Singapore Dollars, (vi) Swiss Franc and (vii) any other currency approved in accordance with Section 2.13.4(iii) [Requests for Additional Optional Currencies].  Subject to Section 2.13.4 [European Monetary Union], each Optional Currency must be the lawful currency of the specified country.

4.            Section 2.8.1 [Letter of Credit Sublimit] of the Credit Agreement is hereby amended by inserting the following sentence at the end of such Section:

Notwithstanding anything to the contrary herein, the Issuing Lender shall have no obligation to issue any Letter of Credit if such Letter of Credit is to be denominated in a currency other than U.S. Dollars or an Optional Currency.

5.            Clause (iii) of Section 2.13.4 [Requests for Additional Currencies] is hereby amended and restated in its entirety as follows:

(iii)      Requests for Additional Optional Currencies.  The Borrowing Agent may deliver to the Administrative Agent a written request that Revolving Credit Loans hereunder also be permitted to be made, and/or Letters of Credit be permitted to be issued, in any other lawful currency (other than Dollars), in addition to the currencies specified in the definition of "Optional Currency" herein, provided that such currency must be freely traded in the offshore interbank foreign exchange markets, freely transferable, freely convertible into Dollars and available to the Lenders in the Relevant Interbank Market.  In the case of any such request with respect to the making of Revolving Credit Loans, such request shall be subject to the approval of the Administrative Agent and all of the Lenders; and in the case of any such request with respect to the issuance of Letters of Credit, such request shall be subject to the approval of the Administrative Agent and the Issuing Lender.  Promptly after receiving any such request, the Administrative Agent will notify (a) the Lenders of any such request relating to the making of Revolving Credit Loans, or (b) the Issuing Lender of any such request relating to the issuance of Letters of Credit.  The Administrative Agent will promptly notify the Borrowing Agent of the acceptance or rejection thereof by the Lenders or the Issuing Lender, as applicable.  The requested currency shall be approved as an Optional Currency with respect to Revolving Credit Loans hereunder only if the Administrative Agent and all of the Lenders approve of the Borrowing Agent's request.  The requested currency shall be approved as an Optional Currency with respect to Letters of Credit hereunder only if the Administrative Agent and the Issuing Lender approve of the Borrowing Agent’s request.

6.            Section 8.2.5 [Dividends and Related Distributions] is hereby amended and restated in its entirety as follows:

Each of the Loan Parties shall not, and shall not permit any of its Subsidiaries to, make or pay, or agree to become or remain liable to make or pay, any dividend or other distribution of any nature (whether in cash, property, securities or otherwise) on account of or in respect of its shares of capital stock, partnership interests or limited liability company interests or on account of the purchase, redemption, retirement or acquisition of its shares of capital stock (or warrants, options or rights therefor), partnership interests or limited liability company interests, except for (i) dividends or other distributions payable to another Loan Party or wholly-owned Subsidiary of a Loan Party, (ii) any other dividends or distributions in an aggregate maximum amount during any calendar year not to exceed Fourteen Million and 00/100 Dollars ($14,000,000.00) so long as both immediately before and immediately after giving effect thereto (a) there exists no Event of Default or Potential Default and (b) the sum of (y) cash and Cash Equivalents of the Loan Parties and their Domestic Subsidiaries and (z) Undrawn Availability is not less than Fifty Million and 00/100 Dollars ($50,000,000.00), and (iii) repurchases of its Equity Interests so long as both immediately before and immediately after giving effect thereto (a) there exists no Event of Default or Potential Default, (b) pro forma Leverage Ratio (calculated if such dividend or distribution has been made in the applicable measurement period) for the four (4) consecutive fiscal quarters most recently ended is less than or equal to 2.75 to 1.0 and (c) the sum of (y) cash and Cash Equivalents of the Loan Parties and their Domestic Subsidiaries and (z) Undrawn Availability is not less than Fifty Million and 00/100 Dollars ($50,000,000.00).

7.            Section 11.1.4 [Miscellaneous] is hereby amended and restated in its entirety as follows:

8.            Clause (b) of Schedule 1.1(A) is hereby amended and restated in its entirety as follows:

(b)      The Applicable Margin, the Applicable Letter of Credit Fee Rate and the Applicable Commitment Fee Rate shall be recomputed as of (i) the date of the consummation of the CECA Acquisition based upon the Leverage Ratio as calculated by the Borrowers in accordance with clause (ii)(E) of Section 8.2.6  [Liquidations, Mergers, Consolidations, Acquisitions]; provided however, that the pricing determined as of the date of the consummation of the CECA Acquisition shall continue through the date on which the first Compliance Certificate is due to be delivered following the date of the CECA Acquisition, and (ii) the end of each fiscal quarter ending after the Closing Date based on the Leverage Ratio as of such quarter end; provided, that notwithstanding the foregoing or anything in this Agreement to the contrary, the rates in Level V shall apply to the Applicable Margin, the Applicable Letter of Credit Fee Rate and the Applicable Commitment Fee Rate from the due date of the quarterly Compliance Certificate to be delivered for the fiscal quarter ending March 31, 2017 through the due date of the quarterly Compliance Certificate to be delivered for the fiscal quarter ending September 30, 2017.  Any increase or decrease in the Applicable Margin, the Applicable Letter of Credit Fee Rate and the Applicable Commitment Fee Rate computed as of a quarter end shall be effective on the due date of the quarterly Compliance Certificate to be delivered for the fiscal quarter ending September 30, 2017, or thereafter the date on which the Compliance Certificate evidencing such computation is due to be delivered under Section 8.3.3 [Certificate of Borrowers], as the case may be.  If (i) an acquisition Compliance Certificate is not delivered when due in accordance with Section 8.2.6  [Liquidations, Mergers, Consolidations, Acquisitions] or (ii) a Compliance Certificate is not delivered when due in accordance with such Section 8.3.3 [Certificate of Borrowers], then the rates in Level V shall apply as of the first Business Day after the date on which such Compliance Certificate was required to have been delivered and shall remain in effect until the date on which such Compliance Certificate is delivered.

9.            The amendments set forth in Sections 2 through 8 of this Amendment shall not become effective until the Administrative Agent has received the following, each in form and substance acceptable to the Administrative Agent:

		(a)	
this Amendment, duly executed by the Borrower, the Guarantors, the Lenders and the Administrative Agent;

		(b)	
payment of all fees and expenses owed to the Administrative Agent and its counsel in connection with this Amendment; and

		(c)	
such other documents as may be reasonably requested by the Administrative Agent.

10.            The Loan Parties hereby reconfirm and reaffirm that all representations and warranties, agreements and covenants made by and pursuant to the terms and conditions of the Credit Agreement and in each other Loan Document are true and correct in all material respects (without duplication of any materiality qualifier contained therein), before and after giving effect to this Amendment, as though made on and as of the date hereof, except for those made specifically as of another date, in which case such representations and warranties shall be true and correct in all material respects as of such date or time.

11.            The Loan Parties represent and warrant that no Potential Default or Event of Default exists under the Credit Agreement, nor will any occur as a result of the execution and delivery of this Amendment or the performance or observance of any provision hereof.

12.            Each reference to the Credit Agreement that is made in the Credit Agreement or any other document executed or to be executed in connection therewith shall hereafter be construed as a reference to the Credit Agreement as amended hereby.

Except as amended hereby, all of the terms and conditions of the Credit Agreement and the other Loan Documents shall remain in full force and effect.  This Amendment amends the Credit Agreement and is not a novation thereof.

14.            This Amendment may be executed in any number of counterparts and by the different parties hereto on separate counterparts each of which, when so executed, shall be deemed to be an original, but all such counterparts shall constitute but one and the same instrument.  Delivery of an executed counterpart of a signature page of this Amendment by telecopy or e-mail shall be effective as delivery of a manually executed counterpart of this Amendment.

15.            This Amendment shall be governed by, and shall be construed and enforced in accordance with, the Laws of the Commonwealth of Pennsylvania without regard to its conflict of laws principles.  The Loan Parties hereby consent to the jurisdiction and venue of the courts of the Commonwealth of Pennsylvania sitting in Allegheny County, Pennsylvania and of the United States District Court for the Western District of Pennsylvania, and any appellate court from any thereof, in any action or proceeding arising out of or relating to this Amendment.

TERMS AND CONDITIONS 

Now, therefore, in consideration of the foregoing recitals and the mutual covenants and agreements contained herein, the parties hereto,
intending to be legally bound, do hereby agree as follows: 
 1. Purchase of the Shares.

Purchaser’s name on Exhibit A (the “Purchase Price”). 
 1.2 Placement Agent Fee. The Purchasers
acknowledge that the Company intends to pay to Craig-Hallum Capital Group LLC, in its capacity as the placement agent for the Offering (the “Placement Agent”), a fee in respect of the sale of Shares. The Company shall indemnify and
hold harmless the Purchasers from and against all fees, commissions, or other payments owing by the Company to the Placement Agent or any other persons from or acting on behalf of the Company hereunder. 

1.3 Closing; Closing Date. The completion of the sale and purchase of the Shares (the “Closing”) shall be held

 Page 1 

 
representing the Shares, dated as of the Closing Date), and (ii) each Purchaser, severally and not jointly, will cause a wire transfer in same day funds to be sent to the account of the
Company as instructed in writing by the Company, in an amount representing the Purchase Price for the Shares to be purchased by such Purchaser as set forth in Exhibit A, unless other means of payment shall have been agreed upon by the
Purchasers and the Company. 
 2. Representations and Warranties of the Company. The Company hereby represents and warrants to each Purchaser:

 2.1 Authorization. All corporate action on the part of the Company, its officers, directors, and stockholders necessary for
the authorization, execution, and delivery of this Agreement has been taken. The Company has the requisite corporate power to enter into this Agreement and carry out and perform its obligations under the terms of this Agreement. At the Closing, the
Company will have the requisite corporate power to issue and sell the Shares. This Agreement has been duly authorized, executed, and delivered by the Company and, upon due execution and delivery by the Purchasers, this Agreement will be a valid and
binding agreement of the Company, enforceable against the Company in accordance with its terms, except as rights to indemnity hereunder may be limited by federal or state securities laws and except as enforceability may be limited by bankruptcy,
insolvency, fraudulent transfer, reorganization, moratorium, or similar laws relating to or affecting creditors’ rights generally and to general equitable principles. 

2.2 No Conflict with Other Instruments. The execution, delivery, and performance of this Agreement, the issuance and sale of the
Shares, and the consummation of the actions contemplated by this Agreement will not (i) result in any violation of, be in conflict with, or constitute a default under, with or without the passage of time or the giving of notice: (A) any
provision of the Company’s Certificate of Incorporation or Bylaws as in effect on the date hereof or at the Closing; (B) any contract, instrument, or other agreement to which the Company or any subsidiary is a party or by which it is bound
that has been filed or was required to have been filed as an exhibit to the Company SEC Documents pursuant to Item 601(b)(4) or Item 601(b)(10) of Regulation S-K (each, a “Material Contract”);
or (C) any statute, rule, law, regulation, or order of any governmental agency or body or any court, domestic or foreign, having jurisdiction over the Company, any of its subsidiaries, or any of their respective assets or properties; or
(ii) result in the creation or imposition of any lien, encumbrance, or other adverse claim whatsoever upon any of the properties or assets of the Company or any subsidiary or give to others any rights of termination, acceleration, or
cancellation of any Material Contract, except in the case of (i)(B), (i)(C) and (ii) above, as would not result in a material adverse effect on the Company or its subsidiaries’ (taken as a whole) business, financial condition, properties,
results of operations, prospects, or assets, or its ability to perform its obligations under this Agreement (a “Material Adverse Effect”). 

2.3 Certificate of Incorporation; Bylaws. The Company has made available to the Purchasers true, correct, and complete copies of
the Certificate of Incorporation and Bylaws of the Company, as in effect on the date hereof.

Company and each of its subsidiaries has full power and authority to own, 

  
 Page 2 

 
operate, and occupy its properties and to conduct its business as presently conducted and is duly qualified to transact business and is in good standing in each jurisdiction in which the failure
to so qualify would have a Material Adverse Effect.

of business subsequent to September 30, 2016, and liabilities of the type not required under generally accepted accounting principles to be reflected in such financial statements. Such liabilities incurred subsequent to September 30, 2016,
have not had nor could reasonably be expected to have a Material Adverse Effect. 
 2.6 Capitalization. The authorized capital

capital stock have been duly authorized and validly issued, are fully paid and non-assessable, have been issued and sold in compliance with the registration requirements of federal and state securities laws or
the applicable statutes of limitation have expired, and were not issued in violation of any preemptive rights or similar rights to subscribe for or purchase securities. Except as set forth herein or as disclosed in the Company SEC Documents, there

indirectly, and has no stock or other interest as owner or principal in, any other corporation or partnership, joint venture, association or other business venture or entity (each a “subsidiary”). Each subsidiary is duly
incorporated or organized, validly existing and, to the extent recognized in the jurisdiction of incorporation or organization and expect as would not reasonably be expected to have a Material Adverse Effect, is in good standing under the laws of
its jurisdiction of incorporation or organization and has all requisite power and authority to carry on its business as now conducted. Each subsidiary is duly qualified to transact business and is in good standing in each jurisdiction in which the
failure to so qualify would have a Material Adverse Effect. Except as set forth in the Company SEC Documents, all of the outstanding capital stock or other securities of each subsidiary is owned by the Company, directly or indirectly, free and clear
of any liens, claims, or encumbrances. 
 2.8 Valid Issuance. The Shares are duly authorized and, when issued, sold, delivered
and paid for in accordance with the terms of this Agreement, will be duly and validly authorized and issued, fully paid and non-assessable, free from all taxes, liens, claims, encumbrances, and charges with
respect to the issue thereof; provided, however, that the Shares may be subject to restrictions on transfer under state and/or federal securities laws or as otherwise set forth herein. The issuance, sale, and delivery of the Shares in accordance
with the terms hereof, will not be subject to preemptive rights of stockholders of the Company. 
 2.9 Offering. Assuming the
accuracy of the representations of each Purchaser in Sections 3.3 and 3.8 of this Agreement on the date hereof and on the Closing Date, the offer, issue and sale of the Shares to the Purchasers as contemplated hereby are and will be exempt from
the registration and prospectus delivery requirements of the Securities Act and have been or will be registered or qualified (or are or will be exempt from registration and qualification) under the registration, permit, or qualification requirements
of all applicable state securities laws. Neither the Company, nor any of its affiliates, nor any person acting on its or their behalf, has directly or indirectly made any offers or sales of any security or solicited any offers to buy any security
under circumstances that would require registration under the Securities Act of the issuance of the Shares to the Purchasers. Other than the Company SEC Documents, the Company has not distributed and will not distribute prior to the Closing Date any
offering materials in connection with the offering and sale of the Shares. The Company has not taken any action to sell, offer for sale or solicit offers to buy any securities of the Company which would bring the offer, issuance or sale of the
Shares within the provisions of Section 5 of the Securities Act, unless such offer, issuance or sale was or shall be within the exemptions of Section 4 of the Securities Act.

 2.10 Litigation. Except as set forth in the Company SEC Documents, there is no
action, suit, proceeding, or investigation pending or, to the actual knowledge of the executive officers (as such term is defined in Rule 405 under the Securities Act) of the Company (the “Company’s Knowledge”),
currently threatened against the Company or any of its subsidiaries that (i) if adversely determined would reasonably be expected to have a Material Adverse Effect or (ii) would be required to be disclosed in the Company’s Annual
Report on Form 10-K under the requirements of Item 103 of Regulation S-K. The foregoing includes, without limitation, any action, suit, proceeding, or investigation,
pending or threatened, that questions the validity of this Agreement or the right of the Company to enter into this Agreement and perform its obligations hereunder. Neither the Company nor any subsidiary is subject to any injunction, judgment,
decree, or order of any court, regulatory body, arbitral panel, administrative agency, or other government body which would reasonably be expected to have a Material Adverse Effect.

in which it is conducting business, including, without limitation, all applicable local, state, and federal environmental laws and regulations, except where failure to be so in compliance would not have a Material Adverse Effect. Each of the Company
and the subsidiaries has all necessary franchises, licenses, certificates, and other authorizations from any foreign, federal, state, or local government or governmental agency, department, or body that are currently necessary for the operation of
the business of the Company and its subsidiaries as currently conducted, except where the failure to currently possess such franchises, licenses, certificates, and other authorizations would not reasonably be expected to have a Material Adverse
Effect. 
 2.14 No Material Changes. Except as disclosed in the Company SEC Documents, since September 30, 2016, there
has not been any change that has had or would reasonably be expected to have a Material Adverse Effect. Since September 30, 2016, the Company has not declared or paid any dividend or distribution on its capital stock.

Neither the Company nor any subsidiary is making unauthorized use of any confidential information or trade secrets of any person. The activities of any of the employees on behalf of the Company or of any subsidiary do not violate any agreements or
arrangements between such employees and third parties are related to confidential information or trade secrets of third parties or that restrict any such employee’s engagement in business activity of any nature.

Knowledge, no other party to any such license or other agreement is in default thereunder (and there exists no condition which, with the passage of time or otherwise, would constitute a default by such other party). 

(f) The Company and its subsidiaries have complied in all material respects with their respective privacy policies and other legal
obligations regarding the collection, use, transfer, storage, protection, disposal, and disclosure by the Company and its subsidiaries of personal and user information gathered or accessed in the course of their operations. With respect to all such

2.26 Disclosure Controls and Internal Controls. 

(a) The Company has established and maintains disclosure controls and procedures (as such term is defined in Rule 13a-15 under the Exchange Act), which (i) are designed to ensure that material information relating to the Company is made known to the Company’s principal executive officer and its principal financial
officer by others within the Company, particularly during the periods in which the periodic reports required under the Exchange Act are being prepared; and (ii) provide for the periodic evaluation of the effectiveness of such disclosure
controls and procedures as of the end of the period covered by the Company’s most recent annual or quarterly report filed with the SEC.

provide reasonable assurance that (i) transactions are executed in accordance with management’s general or specific authorizations, (ii) transactions are recorded as necessary to permit preparation of financial statements in
conformity with generally accepted accounting principles and to maintain asset and liability accountability, (iii) access to assets or incurrence of liabilities is permitted only in accordance with management’s general or specific

disclosure controls and procedures (as such term is defined in Rule 13a-14 under the Exchange Act) and designed such controls and procedures to ensure that information required to be disclosed by the Company
in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the rules and forms of the SEC, including, without limitation, controls and procedures designed to
ensure that information required to be disclosed by the Company in the reports that it files or submits under 

  
 Page 8 

 
the Exchange Act is made known to the Company’s principal executive officer or officers and its principal financial officer or officers, as appropriate, to allow timely decisions regarding
required disclosure. To the Company’s Knowledge, except as described in the Company SEC Documents, there is no (i) significant deficiency in the design or operation of internal controls which could adversely affect the Company’s or
any of its subsidiary’s ability to record, process, summarize and report financial data or any material weaknesses in internal controls; or (ii) fraud, whether or not material, that involves management or other employees who have a
significant role in the Company’s or any of its subsidiary’s internal controls. 
 (c) Since the date of the most recent
evaluation of such disclosure controls and procedures, except as described in the Company SEC Documents, there have been no changes that have materially affected, or are reasonably likely to materially affect, the Company’s or any of its
subsidiary’s internal control over financial reporting, including any corrective actions with regard to significant deficiencies and material weaknesses. 

(d) Except as described in the Company SEC Documents, there are no material off-balance sheet
arrangements (as defined in Item 303 of Regulation S-K), or any other relationships with unconsolidated entities (in which the Company or its control persons have an equity interest) that may have a material
current or future effect on the Company’s or any of its subsidiary’s financial condition, revenues or expenses, changes in financial condition, results of operations, liquidity, capital expenditures, or capital resources. 

(e) To the Company’s Knowledge, except as described in the Company SEC Documents, neither the board of directors nor its audit
committee has been informed, nor, to the Company’s Knowledge, is any director of the Company aware, of (1) any significant deficiencies in the design or operation of the Company’s internal controls which could adversely affect the
Company’s or any subsidiary’s ability to record, process, summarize and report financial data or any material weakness in the Company’s or any subsidiary’s internal controls; or (2) any fraud, whether or not material, that
involves management or other employees of the Company or any of its subsidiaries who have a significant role in the Company’s or any subsidiary’s internal controls. 

2.27 No General Solicitation. Neither the Company, nor any of its affiliates, nor any person acting on its or their behalf, has
engaged in any form of general solicitation or general advertising (within the meaning of Regulation D promulgated under the Securities Act) in connection with the offer or sale of the Shares. 

2.28 Application of Takeover Protections; Rights Agreement. The Company has taken all necessary action, if any, in order to
render inapplicable any control share acquisition, business combination, poison pill (including any distribution under a rights agreement), or other similar anti-takeover provision under the Certificate of Incorporation or the laws of the
jurisdiction of its formation which is or could become applicable to any Purchaser as a result of the transactions contemplated by this Agreement, including, without limitation, the Company’s issuance of the Shares and any Purchaser’s
ownership of the Shares. The Company has not adopted a stockholder rights plan or similar arrangement relating to accumulations of beneficial ownership of Common Stock or a change in control of the Company. 

2.29 Foreign Corrupt Practices. Neither the Company nor any of its subsidiaries nor, to the Company’s Knowledge, any
director, officer, agent, employee or other person acting on behalf of the Company or any of its subsidiaries has, in the course of its actions for, or on behalf

officer intends to leave the Company or otherwise terminate such officer’s employment with the Company. No executive officer of the Company, to the Company’s Knowledge, is, or is now reasonably expected to be, in violation of any material
term of any employment contract, confidentiality, disclosure, or proprietary information agreement, non-competition agreement, or any other contract or agreement or any restrictive covenant, and the continued
employment of each such executive officer would not reasonably be expected to subject the Company to any liability with respect to any of the foregoing matters. 

The Company and each of its subsidiaries is in compliance with all federal, state, local, and foreign laws and regulations respecting labor,
employment and employment practices and benefits, terms and conditions of employment and wages and hours, except where failure to be in compliance would not, either individually or in the aggregate, reasonably be expected to result in a Material
Adverse Effect.

all Environmental Laws (as hereinafter defined), (ii) has received all permits, licenses, or other approvals required of it under applicable Environmental Laws to conduct its business, and (iii) is in compliance with all terms and conditions of
any such permit, license or approval where, in each of the foregoing clauses (i), (ii), and (iii), the failure to so comply could be reasonably expected to have, individually or in the aggregate, a Material Adverse Effect. The term

subsurface strata), including, without limitation, laws relating to emissions, discharges, releases or threatened releases of chemicals, pollutants, contaminants, or toxic or hazardous substances or wastes (collectively, “Hazardous
Materials”) into the environment, or otherwise relating to the manufacture, processing, distribution, use, treatment, storage, disposal, transport or handling of Hazardous Materials, as well as all authorizations, codes, decrees,
demands or demand letters, injunctions, judgments, licenses, notices or notice letters, orders, permits, plans or regulations issued, entered, promulgated or approved thereunder.

Section 21E of the Exchange Act) made by the Company or any of its officers or directors contained in the SEC Documents, or made available to the public generally since September 30, 2016, has been made or reaffirmed without a reasonable basis
or has been disclosed other than in good faith. 

  
 Page 10 

 2.34 No Manipulation; Disclosure of Information. The Company has not taken and will
not take any action designed to or that might reasonably be expected to cause or result in an unlawful manipulation of the price of the Common Stock to facilitate the sale or resale of the Shares. With the exception of the proposed sale of Shares as
contemplated herein (as to which the Company makes no representation), neither the Company nor any other person acting on its behalf has provided any of the Purchasers or their agents or counsel with any information that constitutes or might
constitute material, non-public information. The Company understands and confirms that the Purchasers shall be relying on the foregoing representations in effecting transactions in securities of the Company.
All disclosures provided to the Purchasers regarding the Company, its business and the transactions contemplated hereby, including the exhibits to this Agreement, furnished by the Company are true and correct in all material respects and do not
contain any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements made therein, in light of the circumstances under which they were made, not misleading. 

2.35 Certain Acknowledgements. Anything in this Agreement or elsewhere herein to the contrary notwithstanding (except for
Sections 3.7 and 6.11 hereof), it is understood and acknowledged by the Company that: (i) none of the Purchasers has been asked by the Company to agree, nor has any Purchaser agreed, to desist from purchasing or selling, long and/or short,
securities of the Company, or “derivative” securities based on securities issued by the Company or to hold the Shares for any specified term; (ii) past or future open market or other transactions by any Purchaser, specifically
including, without limitation, Short Sales (as defined below) or “derivative” transactions, before or after the closing of this or future private placement transactions, may negatively impact the market price of the Company’s
publicly-traded securities; (iii) any Purchaser, and counter-parties in “derivative” transactions to which any such Purchaser is a party, directly or indirectly, presently may have a “short” position in the Common Stock, and
(iv) each Purchaser shall not be deemed to have any affiliation with or control over any arm’s length counter-party in any “derivative” transaction. The Company further understands and acknowledges that (y) one or more
Purchasers may engage in hedging activities at various times during the period that the Shares are outstanding, and (z) such hedging activities (if any) could reduce the value of the existing stockholders’ equity interests in the Company
at and after the time that the hedging activities are being conducted. The Company acknowledges that such aforementioned hedging activities do not constitute a breach hereof. 

2.36 No Additional Agreements. Other than with respect to closing mechanics, the Company has no other agreements or
understandings (including, without limitation, side letters) with any Purchaser or other person to purchase Shares on terms more favorable to such person than as set forth herein. 

2.37 No “Bad Actor” Disqualification. The Company has exercised reasonable care, in accordance with SEC rules and
guidance, and has conducted a factual inquiry, the nature and scope of which reflect reasonable care under the relevant facts and circumstances, to determine whether any Covered Person (as defined below) is subject to any of the “bad
actor” disqualifications described in Rule 506(d)(1)(i) to (viii) under the Securities Act (“Disqualification Events”). To the Company’s knowledge, after conducting such sufficiently diligent factual inquiries, no
Covered Person is subject to a Disqualification Event, except for a 

  
 Page 11 

 
Disqualification Event covered by Rule 506(d)(2) or (d)(3) under the Securities Act. The Company has complied, to the extent applicable, with any disclosure obligations under Rule 506(e) under
the Securities Act. “Covered Persons” are those persons specified in Rule 506(d)(1) under the Securities Act, including the Company; any predecessor or affiliate of the Company; any director, executive officer, other officer
participating in the offering, general partner or managing member of the Company; any beneficial owner of 20% or more of the Company’s outstanding voting equity securities, calculated on the basis of voting power; any promoter (as defined in
Rule 405 under the Securities Act) connected with the Company in any capacity at the time of the sale of the Securities; and any person that has been or will be paid (directly or indirectly) remuneration for solicitation of purchasers in connection
with the sale of the Shares (a “Solicitor”), any general partner or managing member of any Solicitor, and any director, executive officer or other officer participating in the offering of any Solicitor or general partner or managing
member of any Solicitor. 
 3. Representations and Warranties of the Purchasers. Each Purchaser, severally and not jointly, hereby represents
and warrants to the Company as follows: 
 3.1 Legal Power. If the Purchaser is a corporation, limited partnership, or limited
liability company, such Purchaser is validly existing and has all requisite corporate, partnership, or limited liability company power and authority to invest in the Shares pursuant to this Agreement. The Purchaser has the requisite authority to
enter into this Agreement and to carry out and perform its obligations under the terms of this Agreement. All action on the Purchaser’s part required for the lawful execution and delivery of this Agreement have been or will be effectively taken
prior to the Closing. 
 3.2 Due Execution. This Agreement has been duly authorized, executed, and delivered by the Purchaser,
and, upon due execution and delivery by the Company, this Agreement will be a valid and binding agreement and obligation of the Purchaser enforceable against such Purchaser in accordance with its terms, except as rights to indemnity hereunder may be
limited by federal or state securities laws and except as enforceability may be limited by bankruptcy, insolvency, reorganization, moratorium or similar laws affecting creditors’ rights generally or by equitable principles. 

3.3 Investment Representations. 

(a) Investment for Own Account. The Purchaser is acquiring the Shares for its own account, not as nominee or agent, and not with
a view to, or for resale in connection with, any distribution or public offering thereof within the meaning of the Securities Act, and such Purchaser has no present intention of selling, granting any participation in, or otherwise distributing the
same in violation of the Securities Act; provided, however, that by making the representations herein, the Purchaser does not agree to hold any of the Shares for any minimum or specific term and reserves the right to dispose of the securities at any
time in accordance with or pursuant to a registration statement or an exemption from the registration requirements of the Securities Act. Such Purchaser is not a broker-dealer registered with the SEC under the Exchange Act or an entity engaged in a
business that would require it to be so registered. 
 (b) Transfer Restrictions; Legends. The Purchaser understands that
(i) the Shares are characterized as “restricted securities” under the U.S. federal securities laws inasmuch as they have not been registered under the Securities Act and are being acquired from the Company in a transaction not
involving a public offering and that under such laws and applicable 

  
 Page 12 

 
regulations such securities may be resold without registration under the Securities Act only in certain limited circumstances; (ii) the Shares are being offered and sold pursuant to an
exemption from registration, based in part upon the Company’s reliance upon the statements and representations made by the Purchasers in this Agreement, and that the Shares must be held by the Purchaser indefinitely, and that the Purchaser
must, therefore, bear the economic risk of such investment indefinitely, unless a subsequent disposition thereof is registered under the Securities Act or is exempt from such registration; (iii) the Shares will be subject to the following
legend until the earlier of (1) such date as the Shares have been registered for resale by the Purchaser or (2) the date the Shares are eligible for sale under Rule 144 under the Securities Act or any successor rule (“Rule
144”): 
 THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE
“SECURITIES ACT”), OR UNDER THE SECURITIES LAWS OF ANY STATES. THESE SECURITIES ARE SUBJECT TO RESTRICTIONS ON TRANSFERABILITY AND RESALE AND MAY NOT BE TRANSFERRED OR RESOLD EXCEPT AS PERMITTED UNDER THE SECURITIES ACT AND THE
APPLICABLE STATE SECURITIES LAWS, PURSUANT TO REGISTRATION OR EXEMPTION THEREFROM. UNLESS SOLD PURSUANT TO EITHER AN EFFECTIVE REGISTRATION STATEMENT OR RULE 144 UNDER THE SECURITIES ACT, THE ISSUER OF THESE SECURITIES MAY REQUIRE AN OPINION OF
COUNSEL IN FORM AND SUBSTANCE SATISFACTORY TO THE ISSUER TO THE EFFECT THAT ANY PROPOSED TRANSFER OR RESALE IS IN COMPLIANCE WITH THE SECURITIES ACT AND ANY APPLICABLE STATE SECURITIES LAWS. 

(iv) the Company will instruct any transfer agent not to register the transfer of the Shares (or any portion thereof) until the applicable date set forth in
clause (iii) above unless (A) the conditions specified in the foregoing legends are satisfied, (B) if the opinion of counsel referred to above is to the further effect that such legend is not required in order to establish compliance
with any provisions of the Securities Act or this Agreement, (C) if the Purchaser provides the Company with reasonable assurance, such as through a representation letter, that the Shares may be sold pursuant to Rule 144 or (D) other
satisfactory assurances, as determined by the Company, of such nature are given to the Company. If so required by the Company’s transfer agent, the Company shall cause its counsel to issue and deliver a legal opinion to the transfer agent to
effect the removal of the restrictive legend contemplated by this Agreement. 
 The Company acknowledges and agrees that a Purchaser may
from time to time pledge, and/or grant a security interest in some or all of the Shares pursuant to a bona fide margin agreement in connection with a bona fide margin account and, if required under the terms of such agreement or account, the
Purchaser may transfer pledged or secured Shares to the pledgees or secured parties. Such a pledge or transfer shall not be subject to approval or consent of the Company and no legal opinion of legal counsel to the pledgee, secured party or pledgor
shall be required in connection with the pledge, but such legal opinion may be required in connection with a subsequent transfer following default by the Purchaser transferee of the pledge. No notice shall be required of such pledge. At the
appropriate Purchaser’s expense, the Company will execute and deliver such reasonable documentation as a pledgee or secured party of Shares may reasonably request in connection with a pledge or transfer of the Shares including the preparation

  
 Page 13 

 
and filing of any required prospectus supplement under Rule 424(b)(3) of the Securities Act or other applicable provision of the Securities Act to appropriately amend the list of Selling
Stockholders thereunder. 
 The Shares shall not bear any legend (including the legend set forth in this Section): (i) following the
effectiveness of a registration statement (including the Registration Statement) covering the Shares, or (ii) following a sale of such Shares pursuant to Rule 144, or (iii) while such Shares are eligible for sale under Rule 144. Following such
time as restrictive legends are not required to be placed on the Shares, the Company will, no later than three business days following the delivery by a Purchaser to the Company or the Company’s transfer agent of a certificate representing the
Shares, if such Shares are certificated, containing a restrictive legend or request removal of such legend from the book entry position of the Purchaser for the Shares, if such Shares are uncertificated, deliver or cause to be delivered to such
Purchaser Shares that are free from the restrictive legend provided for in this Section 3.3(b). Upon request of a Purchaser, the Company shall use commercially reasonable efforts to have the Company’s transfer agent promptly effect the
removal of the legend hereunder after such time as restrictive legends are not required on the Shares, including delivery of a certificate or opinion of counsel if required by the Company’s transfer agent. The Company may not make any notation
on its records or give instructions to any transfer agent of the Company that enlarge the restrictions on transfer set forth in this Section. Shares subject to legend removal hereunder shall be transmitted by the transfer agent of the Company to the
Purchasers by crediting the account of the Purchaser’s prime broker with the Depository Trust Company system. The Company will pay all fees and expenses of its transfer agent and the Depository Trust Company in connection with the removal of
legends pursuant to this Section 3.3(b). 
 Each Purchaser, severally and not jointly with the other Purchasers, agrees that the
removal of the restrictive legend from the Shares as set forth in this Section 3.3(b) is predicated upon the Company’s reliance that the Purchaser will sell any Shares pursuant to either the registration requirements of the Securities Act,
including any applicable prospectus delivery requirements, or an exemption therefrom. 
 (c) Financial Sophistication; Due
Diligence. The Purchaser can bear the economic risk and complete loss of its investment in the Shares and has such knowledge and experience in financial or business matters that it is capable of evaluating the merits and risks of the investment
in connection with the transactions contemplated in this Agreement. Such Purchaser has, in connection with its decision to purchase the Shares, relied only upon the representations and warranties contained herein and the information contained in the
Company SEC Documents. Further, the Purchaser has had such opportunity to obtain additional information and to ask questions of, and receive answers from, the Company, concerning the terms and conditions of the investment and the business and
affairs of the Company, as the Purchaser considers necessary in order to form an investment decision. Such Purchaser acknowledges receipt of copies of the Company SEC Documents. 

(d) Accredited Investor Status. The Purchaser is an “accredited investor” as such term is defined in Rule 501(a) of
the rules and regulations promulgated under the Securities Act. 
 (e) Residency. The Purchaser is organized under the laws of
the jurisdiction set forth beneath such Purchaser’s name on the signature page attached hereto, and its principal place of operations is in the jurisdiction set forth beneath such Purchaser’s name on the signature page attached hereto.

  
 Page 14 

 (f) General Solicitation. The Purchaser is not purchasing the Shares as a result of
any advertisement, article, notice, or other communication regarding the Shares published in any newspaper, magazine, or similar media or broadcast over the television or radio or presented at any seminar or any other general solicitation or general
advertisement. Prior to the time that the Purchaser was first contacted by the Company or the Placement Agent, such Purchaser had a pre-existing and substantial relationship with the Company or the Placement
Agent. 
 3.4 No Investment, Tax or Legal Advice. Each Purchaser understands that nothing in the Company SEC Documents, this
Agreement, or any other materials presented to the Purchaser in connection with the purchase and sale of the Shares constitutes legal, tax, or investment advice. Each Purchaser has consulted such legal, tax, and investment advisors as it, in its
sole discretion, has deemed necessary or appropriate in connection with its purchase of Shares. 
 3.5 Additional
Acknowledgement. Each Purchaser acknowledges that it has independently evaluated the merits of the transactions contemplated by this Agreement, that it has independently determined to enter into the transactions contemplated hereby, that it is
not relying on any advice from or evaluation by any other person. Each Purchaser acknowledges that the Placement Agent has acted solely as placement agent for the Company in connection with the Offering of the Shares by the Company, that the
information and data provided to the Purchaser in connection with the transaction contemplated hereby has not been subjected to independent verification by the Placement Agent, and that the Placement Agent has made no representation or warranty
whatsoever with respect to the accuracy or completeness of such information, data or other related disclosure material. Each Purchaser acknowledges that it has not taken any actions that would deem the Purchasers to be members of a “group”
for purposes of Section 13(d) of the Exchange Act. 
 3.6 Limited Ownership. The purchase of the Shares issuable to each
Purchaser at the Closing will not result in such Purchaser (individually or together with any other person or entity with whom such Purchaser has identified, or will have identified, itself as part of a “group” in a public filing made with
the SEC involving the Company’s securities) acquiring, or obtaining the right to acquire, in excess of 19.999% of the outstanding shares of Common Stock or voting power of the Company on a post-transaction basis that assumes that the Closing
shall have occurred. Such Purchaser does not presently intend to, along or together with others, make a public filing with the SEC to disclose that it has (or that it together with such other persons or entities have) acquired, or obtained the right
to acquire, as a result of the Closing (when added to any other securities of the Company that it or they then own or have the right to acquire), in excess of 19.999% of the outstanding shares of Common Stock or the voting power of the Company on a
post-transaction basis that assumes that the Closing shall have occurred. 
 3.7 Short Sales and Confidentiality Prior To The Date
Hereof. Other than consummating the transactions contemplated hereunder, such Purchaser has not directly or indirectly, nor has any person or entity acting on behalf of or pursuant to any understanding with such Purchaser, executed any purchases
or sales, including short sales as defined in Rule 200 of Regulation SHO under the Exchange Act (“Short Sales”), of the securities of the Company 

  
 Page 15 

 
during the period commencing from the time that such Purchaser first learned of the material terms of this offering (whether by written or oral communication) until the date hereof
(“Discussion Time”). Notwithstanding the foregoing, in the case of a Purchaser that is a multi-managed investment vehicle whereby separate portfolio managers manage separate portions of such Purchaser’s assets and the portfolio
managers have no direct knowledge of the investment decisions made by the portfolio managers managing other portions of such Purchaser’s assets, the representation set forth above shall only apply with respect to the portion of assets managed
by the portfolio manager that made the investment decision to purchase the securities covered by this Agreement. Other than to other persons party to this Agreement, such Purchaser has maintained the confidentiality of all disclosures made to it in
connection with this transaction (including the existence and terms of this transaction). Notwithstanding the foregoing, for avoidance of doubt, nothing contained herein shall constitute a representation or warranty, or preclude any actions, with
respect to the identification of the availability of, or securing of, available shares to borrow in order to effect short sales or similar transactions in the future. 

3.8 “Bad Actor” Matters. Each Purchaser hereby represents that no Disqualification Events are applicable to Purchaser
or any of its Rule 506(d) Related Parties (as defined below), except, if applicable, for a Disqualification Event as to which Rule 506(d)(2)(ii) or (iii) or (d)(3) is applicable. Purchaser hereby agrees that it shall notify the Company promptly
in writing in the event a Disqualification Event becomes applicable to Purchaser or any of its Rule 506(d) Related Parties, except, if applicable, for a Disqualification Event as to which Rule 506(d)(2)(ii) or (iii) or (d)(3) is applicable. For
purposes of this 3.8, “Rule 506(d) Related Party” shall mean a person or entity that is a beneficial owner of Purchaser’s securities for purposes of Rule 506(d) of the Securities Act. 

3.9 Governmental Review. Each Purchaser understands that no United States federal or state agency or any other government or
governmental agency has passed upon or made any recommendation or endorsement of the Shares or an investment therein. 
 3.10.
Foreign Investors. If the Purchaser is not a United States person (as defined by Section 7701(a)(30) of the Internal Revenue Code of 1986, as amended), the Purchaser hereby represents that it has satisfied itself as to the full
observance of the laws of its jurisdiction in connection with any invitation to subscribe for the Shares or any use of this Agreement, including (i) the legal requirements within its jurisdiction for the purchase of the Shares, (ii) any
foreign exchange restrictions applicable to such purchase, (iii) any governmental or other consents that may need to be obtained, and (iv) the income tax and other tax consequences, if any, that may be relevant to the purchase, holding,
redemption, sale, or transfer of the Shares. The Purchaser’s subscription and payment for and continued beneficial ownership of the Shares will not violate any applicable securities or other laws of the Purchaser’s jurisdiction. 

4. Conditions to Closing. 
 4.1
Conditions to Obligations of Purchasers at Closing. Each Purchaser’s obligation to purchase the Shares at the Closing is subject to the fulfillment to that Purchaser’s reasonable satisfaction, on or prior to the Closing, of all of
the following conditions, any of which may be waived by the Purchaser:

materiality or Material Adverse Effect, in all respects) on the Closing Date with the same force and effect as if they had been made on and as of said date (expect to the extent any such
representation or warranty is made as of another specific date, in which case such representation or warranty shall be so true and correct as of such date) and the Company shall have performed and complied with all obligations and conditions herein

enjoining the sale of the Shares shall have been issued and no proceedings for such purpose shall be pending or, to the Company’s Knowledge, threatened by the SEC, or any governmental authority having jurisdiction over this transaction. At the
time of the Closing, the sale and issuance of the Shares shall be legally permitted by all laws and regulations to which Purchasers and the Company are subject. No litigation, statute, rule, regulation, executive order, decree, ruling, or injunction
will have been enacted, entered, promulgated, or endorsed by or in any court or governmental authority of competent jurisdiction or any self-regulatory organization having authority over the matters contemplated hereby which prohibits the
consummation of any of the transactions contemplated by this Agreement.

(f) Trading and Listing. Trading and listing of the Common Stock on the Principal Market shall not have been suspended by the
SEC or the Principal Market. 
 (g) Market Listing. The Company will comply with all of the requirements of the Financial

 4.2 Conditions to Obligations of the Company. The
Company’s obligation to issue and sell the Shares at the Closing is subject to the fulfillment to the Company’s reasonable satisfaction, on or prior to the Closing of the following conditions, any of which may be waived by the Company:

 (a) Representations and Warranties True. The representations and warranties made by the Purchasers in Section 3 shall
be true and correct in all material respects on the Closing Date with the same force and effect as if they had been made on and as of said date.

regulatory body of the United States or of any state that are required in connection with the lawful sale and issuance of the Shares shall have been duly obtained and shall be effective on and as of the Closing. No stop order or other order
enjoining the sale of the Shares shall have been issued and no proceedings for such purpose shall be pending or, to the Company’s Knowledge, threatened by the SEC, or any governmental authority having jurisdiction over this transaction. At the
time of the Closing, the sale and issuance of the Shares shall be legally permitted by all laws and regulations to which the Purchasers and the Company are subject. No litigation, statute, rule, regulation, executive order, decree, ruling, or
injunction will have been enacted, entered, promulgated, or endorsed by or in any court or governmental authority of competent jurisdiction or any self-regulatory organization having authority over the matters contemplated hereby which prohibits the
consummation of any of the transactions contemplated by this Agreement. 
 (d) Execution of Agreements. The Purchasers shall
have executed this Agreement and delivered this Agreement to the Company. 
 4.3 Termination of Obligations to Effect Closing;
Effects. 
 (a) Termination. The obligations of the Company, on the one hand, and the Purchasers, on the other hand, to
effect the Closing shall terminate as follows: 
 (i) Upon the mutual written consent of the Company and the Purchasers; 

  
 Page 18 

 (ii) By the Company if any of the conditions set forth in Section 4.2 shall have become
incapable of fulfillment, and shall not have been waived by the Company; 
 (iii) By a Purchaser (with respect to itself only) if any of
the conditions set forth in Section 4.1 shall have become incapable of fulfillment, and shall not have been waived by such Purchaser; or 

(iv) By either the Company or any Purchaser (with respect to itself only) if the Closing has not occurred on or prior to March 3, 2017;

 provided, however, that, except in the case of clause (i) above, the party seeking to terminate its obligation to effect the Closing shall not then
be in breach of any of its representations, warranties, covenants, or agreements contained in this Agreement if such breach has resulted in the circumstances giving rise to such party’s seeking to terminate its obligation to effect the Closing.

 (b) Effect of Termination. In the event of termination by the Company or any Purchaser of its obligations to effect the
Closing pursuant to this Section 4.3, written notice thereof shall forthwith be given to the other Purchasers by the Company and the other Purchasers shall have the right to terminate their obligations to effect the Closing upon written notice
to the Company and the other Purchasers. Nothing in this Section 4.3 shall be deemed to release any party from any liability for any breach by such party of the terms and provisions of this Agreement or to impair the right of any party to
compel specific performance by any other party of its obligations under this Agreement. 
 5. Additional Covenants. 

5.1 Reporting Status. The Company agrees to use its commercially reasonable efforts to file with the SEC, in a timely manner all
reports and other documents required of the Company under the Exchange Act. The Company will take such actions as a Purchaser may reasonably request, to the extent required from time to time to enable such Purchaser to sell the Shares without
registration under the Securities Act or any successor rule or regulation adopted by the SEC. 
 5.2 Listing. The Company will
use commercially reasonable efforts to maintain the listing of its Common Stock, including the Shares, on the Principal Market or an alternative national securities exchange (as defined in the Exchange Act) and will comply in all material respects
with the Company’s reporting, filing and other obligations under the bylaws or rules of such exchanges, if and as applicable. 

5.3 Adjustments in Share Numbers and Prices. In the event of any stock split, subdivision, dividend, or distribution payable in
shares of Common Stock (or other securities or rights convertible into, or entitling the holder thereof to receive directly or indirectly shares of Common Stock), combination or other similar recapitalization or event occurring after the date
hereof, each reference in this Agreement to a number of shares or price per share shall be amended appropriately to account for such event. 

5.4 Confidential Information. Each Purchaser covenants that it will maintain in confidence the receipt and content of any
Suspension Notice (as defined herein) under Section 6.2 until such information (i) becomes generally publicly available other than through a violation of this provision by the Purchaser or its agents or (ii) is required to be
disclosed in legal proceedings (such as by deposition, interrogatory, request for documents, subpoena, civil 

  
 Page 19 

 
investigation demand, filing with any governmental authority or similar process); provided, however, that before making any disclosure in reliance on Section 5.4(ii), the Purchaser will give the
Company at least fifteen (15) days’ prior written notice (or such shorter period as required by law) specifying the circumstances giving rise thereto and, the Purchaser will furnish only that portion of the
non-public information which is legally required and will exercise all reasonable efforts to ensure that confidential treatment will be accorded any non-public
information so furnished; provided, further, that notwithstanding each Purchaser’s agreement to keep such information confidential, each Purchaser makes no such acknowledgement that any such information is material non-public information. 
 5.5 Non-Public Information.
The Company covenants and agrees that neither it nor any other person acting on its behalf will provide any Purchaser or its agents or counsel with any information that the Company believes constitutes material
non-public information, unless prior to disclosure of such information the Company identifies such information as being material non-public information and provides the
Purchaser, such agents or counsel with the opportunity to accept or refuse to accept such material non-public information for review and any Purchaser wishing to obtain such information shall have executed a
written agreement regarding the confidentiality and use of such information. Furthermore, if the Company has disclosed any material non-public information to the Purchaser, the Purchaser has no duty to keep
such information confidential following the public announcement of this transaction. 
 5.6 Restriction on Future Issuances.
The Company will not, from the date of this Agreement through the effective date of the Registration Statement (the “Lock-Up Period”), (a) offer, pledge, announce the intention to sell,
sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase or otherwise transfer or dispose of, directly or indirectly, any shares of Common Stock or any
securities convertible into or exercisable or exchangeable for Common Stock or (b) enter into any swap or other agreement that transfers, in whole or in part, any of the economic consequences of ownership of the Common Stock, whether any such
transaction described in clause (a) or (b) above is to be settled by delivery of Common Stock or such other securities, in cash or otherwise, except for (x) grants of options, shares of Common Stock and other awards to purchase or receive
shares of Common Stock under the Company’s equity incentive plans that are in effect as of or prior to the date hereof or (y) issuances of shares of Common Stock upon the exercise or conversion of securities outstanding as of the date of
this Agreement in accordance with the terms of such securities in effect on the date hereof or upon the exercise of options or other awards granted under the Company’s equity incentive plans. The Company agrees not to accelerate the vesting of
any option or warrant or the lapse of any repurchase right prior to the expiration of the Lock-Up Period, provided that this last sentence of Section 5.6 shall not apply to the acceleration of the vesting
of any option effected in accordance with the terms of an agreement between the Company and the holder of such option or as a result of the terms of the option, each in as in effect as of the date hereof. The Company has caused to be delivered to
the Placement Agent prior to the date of this Agreement a letter, in the form of Exhibit C hereto (the “Lock-Up Agreement”), from each of the Company’s directors and officers. The
Company will enforce the terms of each Lock-Up Agreement and issue stop-transfer instructions to the transfer agent for the Common Stock with respect to any transaction or contemplated transaction that would
constitute a breach of or default under the applicable Lock-Up Agreement. 

  
 Page 20 

 5.7 Restriction on Variable Rate Transactions. From the date hereof until the
twelve-month anniversary of the Closing Date, the Company shall be prohibited from effecting or entering into an agreement to effect any issuance by the Company or any of its subsidiaries of Common Stock or any outstanding convertible instruments,
options or warrants or similar securities (or a combination of units thereof) involving a Variable Rate Transaction. “Variable Rate Transaction” means a transaction in which the Company (i) issues or sells any debt or equity
securities that are convertible into, exchangeable or exercisable for, or include the right to receive additional shares of Common Stock either (A) at a conversion price, exercise price or exchange rate or other price that is based upon and/or
varies with the trading prices of or quotations for the shares of Common Stock at any time after the initial issuance of such debt or equity securities, or (B) with a conversion, exercise or exchange price that is subject to being reset at some
future date after the initial issuance of such debt or equity security or upon the occurrence of specified or contingent events directly or indirectly related to the business of the Company or the market for the Common Stock or (ii) enters into
any agreement, including, but not limited to, an agreement for an equity line of credit or “at-the-market” offering, whereby the Company may issue securities
at a future determined price (other than standard and customary “preemptive” or “participation” rights and excluding any agreement by the Company to issue shares of its Common Stock as consideration in an acquisition, merger or
similar business combination transaction). For the avoidance of doubt, the issuance of a security which is subject to customary anti-dilution protections, including where the conversion, exercise or exchange price is subject to adjustment as a
result of stock splits, reverse stock splits and other similar recapitalization or reclassification events, shall not be deemed to be a “Variable Rate Transaction.” Any Purchaser shall be entitled to obtain injunctive relief against the
Company to preclude any such issuance, which remedy shall be in addition to any right to collect damages. 
 5.8 Equal Treatment
of Purchasers. No consideration (including any modification of this Agreement and any other documents or agreements executed in connection with the transaction contemplated hereunder) shall be offered or paid to any person to amend or consent to
a waiver or modification of any provision of any of this Agreement unless the same consideration is also offered to all of the parties to this Agreement. For clarification purposes, this provision constitutes a separate right granted to each
Purchaser by the Company and negotiated separately by each Purchaser, and is intended for the Company to treat the Purchasers as a class and shall not in any way be construed as the Purchasers acting in concert or as a group with respect to the
purchase, disposition or voting of securities of the Company or otherwise. 
 6. Registration Rights. 

6.1 Registration Procedures and Expenses. 

(a) The Company shall use commercially reasonable efforts to prepare and file with the SEC, as promptly as reasonably practicable
following Closing, but in no event later than 45 days following Closing, a registration statement on Form S-3 (or any successor to Form S-3), covering the resale of the
Registrable Securities (as defined below) (the “S-3 Registration Statement”) and as soon as reasonably practicable thereafter but in no event later than 105 days following the Closing (135
days in the event of a full review of the S-3 Registration Statement by the SEC), to effect such registration and any related qualification or compliance with respect to all Registrable Securities held by the
Purchasers. For purposes of this Agreement, the term “Registrable Securities” shall mean the Shares and any Common Stock of the Company issued as (or issuable upon the conversion or exercise of any warrant, right or other security
which is 

  
 Page 21 

 
issued as) a dividend or other distribution with respect to, or in exchange for or in replacement of, any Shares. In the event that Form S-3 (or any
successor form) is or becomes unavailable to register the resale of the Registrable Securities at any time prior to the expiration of the Purchasers’ registration rights pursuant to Section 6.6, the Company shall prepare and file with the
SEC, as promptly as reasonably practicable following the Closing but in no event later than 45 days following Closing, a registration statement on Form S-1 (or any successor to Form S-1), covering the resale of the Registrable Securities (the “S-1 Registration Statement” and collectively the S-3
Registration Statement, the “Registration Statement”) and as soon as reasonably practicable thereafter but in no event later than 105 days after the Closing (135 days in the event of a full review of the S-1 Registration Statement by the SEC), to effect such registration and any related qualification or compliance with respect to all Registrable Securities held by the Purchasers. If the Registration Statement has
not been either (i) filed with the SEC on or before the date that is 45 days after the Closing (the “Required Filing Date”), or (ii) declared effective by the SEC on or before the date that is 105 days after the Closing,
or 135 days after the Closing in the event of a full review of the Registration Statement by the SEC (the “Required Effective Date”), the Company shall, on the business day immediately following either the Required Filing Date or
the Required Effective Date, as applicable, and each 30th day thereafter, make a payment to the Purchasers as partial liquidated damages for such delay (together, the “Late Registration
Payments”) equal to 1% of the Purchase Price paid for the Shares then owned by the Purchasers until the Registration Statement is declared effective by the SEC. Late Registration Payments will be prorated on a daily basis during each 30 day
period and will be paid to the Purchasers by wire transfer or check within five business days after the earlier of (i) the end of each 30 day period following the Required Filing Date or the Required Effective Date, as applicable or
(ii) the effective date of the Registration Statement. If the Company fails to pay any liquidated damages pursuant to this section in full within seven days after the date payable, the Company will pay interest thereon at a rate of 12% per
annum (or such lesser maximum amount that is permitted to be paid by applicable law) to the Purchasers, accruing daily from the date such liquidated damages are due until such amounts, plus all such interest thereon, are paid in full.
“Business day” means any day except Saturday, Sunday, and any day that is a federal legal holiday in the United States. 

(b) The Company shall use commercially reasonable efforts to: 

(i) prepare and file with the SEC such amendments and supplements to the Registration Statement and the prospectus forming a part
thereof (the “Prospectus”) used in connection therewith as may be necessary or advisable to keep the Registration Statement current and effective for the Registrable Securities held by a Purchaser for a period ending on the earliest
of (i) the second anniversary of the Closing Date, (ii) the date on which all Registrable Securities may be sold pursuant to Rule 144 during any three-month period without the requirement for the Company to be in compliance with the
current public information required under Rule 144(c)(1) or (iii) such time as all Registrable Securities have been sold pursuant to a registration statement or Rule 144. At such time the Company is no longer required to keep the Registration
Statement current and effective for the Registrable Securities held by a Purchaser (the “Registration Statement Termination Date”), that Purchaser will no longer accrue any additional liquidated damages payments pursuant to Sections
6.1(a) or 6.2(c); however, the Company shall still be obligated to make all payments under Sections 6.1(a) or 6.2(c) that were not made prior to the Registration Statement Termination Date for that Purchaser. The Company shall notify each Purchaser
promptly upon the Registration Statement and each post-effective 

  
 Page 22 

 
amendment thereto being declared effective by the SEC and advise each Purchaser that the form of Prospectus contained in the Registration Statement or post-effective amendment thereto, as the
case may be, at the time of effectiveness meets the requirements of Section 10(a) of the Securities Act or that it intends to file a Prospectus pursuant to Rule 424(b) under the Securities Act that meets the requirements of Section 10(a) of the
Securities Act; 
 (ii) furnish to the Purchaser with respect to the Registrable Securities registered under the Registration
Statement such number of copies of the Registration Statement and the Prospectus (including supplemental prospectuses) filed with the SEC in conformance with the requirements of the Securities Act and such other documents as the Purchaser may
reasonably request, in order to facilitate the public sale or other disposition of all or any of the Registrable Securities by the Purchaser; 

(iii) make any necessary blue sky filings; 

(iv) pay the expenses incurred by the Company and the Purchasers in complying with Section 6, including, all registration and
filing fees, FINRA fees, exchange listing fees, printing expenses, fees and disbursements of counsel for the Company, blue sky fees and expenses and the expense of any special audits incident to or required by any such registration (but excluding
attorneys’ fees of any Purchaser and any and all underwriting discounts and selling commissions applicable to the sale of Registrable Securities by the Purchasers); 

(v) advise the Purchasers, promptly after it shall receive notice or obtain knowledge of the issuance of any stop order by the SEC
delaying or suspending the effectiveness of the Registration Statement or of the initiation of any proceeding for that purpose; and it will promptly use its commercially reasonable efforts to prevent the issuance of any stop order or to obtain its
withdrawal at the earliest possible moment if such stop order should be issued; and 
 (vi) with a view to making available to the
Purchaser the benefits of Rule 144 and any other rule or regulation of the SEC that may at any time permit the Purchaser to sell Registrable Securities to the public without registration: (i) make and keep public information available, as those
terms are understood and defined in Rule 144, until the earlier of (A) such date as all of the Registrable Securities qualify to be resold immediately pursuant to Rule 144 or any other rule of similar effect during any three-month period
without the requirement for the Company to be in compliance with the current public information required under Rule 144(c)(1) or (B) such date as all of the Registrable Securities shall have been resold pursuant to Rule 144 (and may be further
resold without restriction); (ii) file with the SEC in a timely manner all reports and other documents required of the Company under the Securities Act and under the Exchange Act; and (iii) furnish to the Purchaser upon request, as long as
the Purchaser owns any Registrable Securities, (A) a written statement by the Company as to whether it has complied with the reporting requirements of the Securities Act and the Exchange Act, (B) a copy of the Company’s most recent
Annual Report on Form 10-K or Quarterly Report on Form 10-Q, and (C) such other information as may be reasonably requested in order to avail the Purchaser of any
rule or regulation of the SEC that permits the selling of any such Registrable Securities without registration.

 The Company understands that the Purchasers disclaim being an underwriter, but acknowledges that a determination
by the SEC that a Purchaser is deemed an underwriter shall not relieve the Company of any obligations it has hereunder. 
 6.2 Transfer
of Shares After Registration; Suspension. 
 (a) Except in the event that Section 6.2(b) applies, the Company shall: (i) if
deemed necessary or advisable by the Company, prepare and file from time to time with the SEC a post-effective amendment to the Registration Statement or a supplement to the related Prospectus or a supplement or amendment to any document
incorporated therein by reference or file any other required document so that such Registration Statement will not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the
statements therein not misleading, and so that, as thereafter delivered to purchasers of the Registrable Securities being sold thereunder, such Prospectus will not contain an untrue statement of a material fact or omit to state a material fact
required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading; (ii) provide the Purchasers copies of any documents filed pursuant to Section 6.2(a)(i); and
(iii) upon request, inform each Purchaser who so requests that the Company has complied with its obligations in Section 6.2(b)(i) (or that, if the Company has filed a post-effective amendment to the Registration Statement which has not yet been
declared effective, the Company will notify the Purchaser to that effect, will use its commercially reasonable efforts to secure the effectiveness of such post-effective amendment as promptly as possible and will promptly notify the Purchaser
pursuant to Section 6.2(b)(i) when the amendment has become effective). Each Purchaser hereby agrees that if the Company provides such Purchaser notice that the Company deems it necessary to file an amendment or prospectus supplement in accordance
with Section 6.2(a)(i) hereof, that each such Purchaser shall immediately cease any and all sales of Registrable Securities under such Registration Statement until such amendment or prospectus supplement has been filed by the Company with the SEC.
In addition, upon a Registration Statement Termination Date, each Purchaser hereby agrees that if the Company provides such Purchaser notice of its intention to remove from registration the Registrable Securities covered by such Registration
Statement which remain unsold, such Purchaser will discontinue any sales of such Registrable Securities and promptly notify the Company of the number of Registrable Securities registered which remain unsold immediately upon receipt of such notice
from the Company. 
 (b) Subject to Section 6.2(c), in the event: (i) of any request by the SEC or any other federal or state
governmental authority during the period of effectiveness of the Registration Statement for amendments or supplements to the Registration Statement or related Prospectus or for additional information; (ii) of the issuance by the SEC or any
other federal or state governmental authority of any stop order suspending the effectiveness of the Registration Statement or the initiation of any proceedings for that purpose; (iii) of the receipt by the Company of any notification with
respect to the suspension of the qualification or exemption from qualification of any of the Registrable Securities for sale in any jurisdiction or the initiation of any proceeding for such purpose; or (iv) of any event or circumstance which
necessitates the making of any changes in the Registration Statement or Prospectus, or any document incorporated or deemed to be incorporated therein by reference, so that, in the case of the Registration Statement, it will not contain any untrue
statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not 

  
 Page 24 

 
misleading, and that in the case of the Prospectus, it will not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make
the statements therein, in the light of the circumstances under which they were made, not misleading; then the Company shall promptly deliver a certificate in writing to the Purchasers (the “Suspension Notice”) to the effect of the
foregoing and, upon receipt of such Suspension Notice, the Purchasers will refrain from selling any Registrable Securities pursuant to the Registration Statement (a “Suspension”) until the Purchasers are advised in writing by the
Company that the current Prospectus may be used, and have received copies from the Company of any additional or supplemental filings that are incorporated or deemed incorporated by reference in any such Prospectus. In the event of any Suspension,
the Company will use its commercially reasonable efforts to cause the use of the Prospectus so suspended to be resumed as soon as reasonably practicable after delivery of a Suspension Notice to the Purchasers. In addition to and without limiting any
other remedies (including, without limitation, at law or at equity) available to the Company and the Purchaser, the Company and the Purchasers shall be entitled to specific performance in the event that the other party fails to comply with the
provisions of this Section 6.2(b). 
 (c) Notwithstanding the foregoing paragraphs of this Section 6.2, the Company shall use
its commercially reasonable efforts to ensure that (i) a Suspension shall not exceed 30 days individually, (ii) Suspensions covering no more than 45 days, in the aggregate, shall occur during any twelve month period and (iii) each
Suspension shall be separated by a period of at least 30 days from a prior Suspension (each Suspension that satisfies the foregoing criteria being referred to herein as a “Qualifying Suspension”). In the event that there occurs a
Suspension (or part thereof) that does not constitute a Qualifying Suspension, the Company shall pay to the Purchasers, on the 30th day following the first day of such Suspension (or the first day
of such part), and on each 30th day thereafter, an amount equal to 1% of the Purchase Price paid for the Shares purchased by such Purchaser and not previously sold by such Purchaser with such
payments to be prorated on a daily basis during each 30 day period and will be paid to the Purchaser by wire transfer or check within five business days after the end of each 30 day period following. 

(d) If a Suspension is not then in effect, the Purchasers may sell Registrable Securities under the Registration Statement, provided
that they comply with any applicable prospectus delivery requirements. Upon receipt of a request therefor, the Company will provide an adequate number of current Prospectuses to each Purchaser and to any other parties reasonably requiring such
Prospectuses. 
 (e) The Company shall cause its transfer agent to issue a certificate without any restrictive legend to a purchaser
of any Registrable Securities from the Purchasers, if no Suspension is in effect at the time of sale, (i) upon the effectiveness of a registration statement (including the Registration Statement) covering the Shares, or (ii) following a
sale of such Shares pursuant to Rule 144, or (iii) while such Shares are eligible for sale under Rule 144. Following such time as restrictive legends are not required to be placed on the Shares, the Company will, no later than three business
days following the delivery by a Purchaser to the Company or the Company’s transfer agent of a certificate representing the Shares containing a restrictive legend, deliver or cause to be delivered to such Purchaser Shares that are free from the
restrictive legend provided for in Section 3.3(b). Upon request of a Purchaser, the Company shall use commercially reasonable efforts to have the Company’s transfer agent to effect the removal of

  
 Page 25 

 
the legend hereunder promptly after such time as restrictive legends are not required on the Shares, including delivery of a certificate or opinion of counsel if required by the Company’s
transfer agent. The Company may not make any notation on its records or give instructions to any transfer agent of the Company that enlarge the restrictions on transfer set forth in Section 3.3. Shares subject to legend removal hereunder shall
be transmitted by the transfer agent of the Company to the Purchasers by crediting the account of the Purchaser’s prime broker with the Depository Trust Company system. The Company will pay all fees and expenses of its transfer agent and the
Depository Trust Company in connection with the removal of legends pursuant to this Section 6.2(e). 
 6.3 Indemnification.
For the purpose of this Section 6.3: 
 (a) the term “Selling Stockholder” shall mean a Purchaser, its
general partners, managing members, managers, executive officers and directors and each person, if any, who controls that Purchaser within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act; 

(b) the term “Registration Statement” shall include any final Prospectus, exhibit, supplement or amendment included in
or relating to, and any document incorporated by reference in, the Registration Statement (or deemed to be a part thereof) referred to in Section 6.1; and 

(c) the term “untrue statement” shall mean any untrue statement or alleged untrue statement of a material fact, or any
omission or alleged omission to state in the Registration Statement a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading. 

(d) The Company agrees to indemnify and hold harmless each Selling Stockholder from and against any losses, claims, damages or
liabilities to which such Selling Stockholder may become subject (under the Securities Act or otherwise) insofar as such losses, claims, damages or liabilities (or actions or proceedings in respect thereof) arise out of, or are based upon
(i) any untrue statement of a material fact contained in the Registration Statement, (ii) any inaccuracy in the representations and warranties of the Company contained in this Agreement or the failure of the Company to perform its
obligations hereunder or (iii) any failure by the Company to fulfill any undertaking included in the Registration Statement, and the Company will reimburse such Selling Stockholder for any reasonable legal expense or other actual accountable out-of-pocket expenses reasonably incurred in investigating, defending or preparing to defend any such action, proceeding or claim; provided, however, that the Company shall
not be liable in any such case to the extent that such loss, claim, damage or liability arises out of, or is based upon, an untrue statement made in such Registration Statement in reliance upon and in conformity with written information furnished to
the Company by or on behalf of such Selling Stockholder specifically for use in preparation of the Registration Statement or the failure of such Selling Stockholder to comply with its covenants and agreements contained herein or any statement or
omission in any Prospectus that is corrected in any subsequent Prospectus that was delivered to the Selling Stockholder prior to the pertinent sale or sales by the Selling Stockholder. 

(e) Each Purchaser severally (as to itself), and not jointly, agrees to indemnify and hold harmless the Company (and each person, if
any, who controls the Company within the 

  
 Page 26 

 
meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, each officer of the Company who signs the Registration Statement and each director of the Company) from
and against any losses, claims, damages or liabilities to which the Company (or any such officer, director or controlling person) may become subject (under the Securities Act or otherwise), insofar as such losses, claims, damages or liabilities (or
actions or proceedings in respect thereof) arise out of, or are based upon, (i) any inaccuracy in the representations and warranties of that Purchaser contained in this Agreement or any failure by that Purchaser to comply with the covenants and
agreements contained herein or (ii) any untrue statement of a material fact contained in the Registration Statement if, and only if, such untrue statement was made in reliance upon and in conformity with written information furnished by or on
behalf of that Purchaser specifically for use in preparation of the Registration Statement, and that Purchaser will reimburse the Company (or such officer, director or controlling person, as the case may be), for any reasonable legal expense or
other reasonable actual accountable out-of-pocket expenses reasonably incurred in investigating, defending or preparing to defend any such action, proceeding or claim.
The obligation to indemnify shall be limited to the net amount of the proceeds received by the Purchaser from the sale of the Registrable Securities pursuant to the Registration Statement. 

(f) Promptly after receipt by any indemnified person of a notice of a claim or the beginning of any action in respect of which
indemnity is to be sought against an indemnifying person pursuant to this Section 6.3, such indemnified person shall notify the indemnifying person in writing of such claim or of the commencement of such action, but the omission to so notify
the indemnifying party will not relieve it from any liability which it may have to any indemnified party under this Section 6.3 (except to the extent that such omission materially and adversely affects the indemnifying party’s ability to
defend such action) or from any liability otherwise than under this Section 6.3. Subject to the provisions hereinafter stated, in case any such action shall be brought against an indemnified person, the indemnifying person shall be entitled to
participate therein, and, to the extent that it shall elect by written notice delivered to the indemnified party promptly after receiving the aforesaid notice from such indemnified party, shall be entitled to assume the defense thereof, with counsel
reasonably satisfactory to such indemnified person. After notice from the indemnifying person to such indemnified person of its election to assume the defense thereof (unless it has failed to assume the defense thereof and appoint counsel reasonably
satisfactory to the indemnified party), such indemnifying person shall not be liable to such indemnified person for any legal expenses subsequently incurred by such indemnified person in connection with the defense thereof; provided, however, that
if there exists or shall exist a conflict of interest that would make it inappropriate, in the reasonable opinion of counsel to the indemnified person, for the same counsel to represent both the indemnified person and such indemnifying person or any
affiliate or associate thereof, the indemnified person shall be entitled to retain its own counsel (who shall not be the same as the opining counsel) at the expense of such indemnifying person; provided, however, that no indemnifying person shall be
responsible for the fees and expenses of more than one separate counsel (together with appropriate local counsel) for all indemnified parties. In no event shall any indemnifying person be liable in respect of any amounts paid in settlement of any
action unless the indemnifying person shall have approved the terms of such settlement; provided that such consent shall not be unreasonably withheld. No indemnifying person shall, without the prior written consent of the indemnified person, effect
any settlement of any pending or threatened proceeding in respect of which any indemnified person is or could reasonably have 

  
 Page 27 

 
been a party and indemnification could have been sought hereunder by such indemnified person, unless such settlement includes an unconditional release of such indemnified person from all
liability on claims that are the subject matter of such proceeding. 
 (g) If the indemnification provided for in this
Section 6.3 is unavailable to or insufficient to hold harmless an indemnified party under subsection (d) or (e) above in respect of any losses, claims, damages or liabilities (or actions or proceedings in respect thereof) referred to
therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect
the relative fault of the Company on the one hand and the liable Purchaser on the other in connection with the statements or omissions or other matters which resulted in such losses, claims, damages or liabilities (or actions in respect thereof), as
well as any other relevant equitable considerations. The relative fault shall be determined by reference to, among other things, in the case of an untrue statement, whether the untrue statement relates to information supplied by the Company on the
one hand or the liable Purchaser on the other and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such untrue statement. The Company and the Purchasers agree that it would not be just and
equitable if contribution pursuant to this subsection (g) were determined by pro rata allocation (even if the Purchasers were treated as one entity for such purpose) or by any other method of allocation which does not take into account the
equitable considerations referred to above in this subsection (g). The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to above in this subsection
(g) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this subsection (g), no
Purchasers shall be required to contribute any amount in excess of the amount by which the net amount received by that Purchaser from the sale of the Registrable Securities to which such loss relates exceeds the amount of any damages which that
Purchaser has otherwise been required to pay to the Company by reason of such untrue statement. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any
person who was not guilty of such fraudulent misrepresentation. The Purchasers’ obligations in this subsection to contribute are several in proportion to their sales of Registrable Securities to which such loss relates and not joint. 

(h) The parties to this Agreement hereby acknowledge that they are sophisticated business persons who were represented by counsel
during the negotiations regarding the provisions hereof including, without limitation, the provisions of this Section 6.3, and are fully informed regarding said provisions. They further acknowledge that the provisions of this Section 6.3
fairly allocate the risks in light of the ability of the parties to investigate the Company and its business in order to assure that adequate disclosure is made in the Registration Statement as required by the Securities Act and the Exchange Act.

 (i) The obligations of the Company and of the Purchasers under this Section 6.3 shall survive completion of any offering of
Registrable Securities in such Registration Statement for a period of two years from the effective date of the Registration Statement. No indemnifying party, in the defense of any such claim or litigation, shall, except with the consent of each
indemnified party, consent to entry of any judgment or enter into any settlement which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect to
such claim or litigation. 

  
 Page 28 

 6.4 Termination of Conditions and Obligations. The conditions precedent imposed by
Section 3 or this Section 6 upon the transferability of the Registrable Securities shall cease and terminate as to any particular number of the Registrable Securities when such Registrable Securities shall have been effectively registered
under the Securities Act and sold or otherwise disposed of in accordance with the intended method of disposition set forth in the Registration Statement covering such Registrable Securities or at such time as an opinion of counsel satisfactory to
the Company shall have been rendered to the effect that such conditions are not necessary in order to comply with the Securities Act. The Company shall request an opinion of counsel promptly upon receipt of a request therefor from a Purchaser. 

6.5 Information Available. So long as the Registration Statement is effective covering the resale of Registrable Securities
owned by a Purchaser, the Company will furnish (or, to the extent such information is available electronically through the Company’s filings with the SEC, the Company will make available via the SEC’s EDGAR system or any successor thereto)
to each Purchaser: 
 (a) as soon as practicable after it is available, one copy of (i) its Annual Report to Stockholders (which
Annual Report shall contain financial statements audited in accordance with generally accepted accounting principles by a national firm of certified public accountants) and (ii) if not included in substance in the Annual Report to Stockholders,
its Annual Report on Form 10-K (the foregoing, in each case, excluding exhibits); 
 (b) upon
the request of the Purchaser, all exhibits excluded by the parenthetical to subparagraph (a)(ii) of this Section 6.5 as filed with the SEC and all other information that is made available to stockholders; and 

(c) upon the reasonable request of the Purchaser, an adequate number of copies of the Prospectuses to supply to any other party
requiring such Prospectuses; and the Company, upon the reasonable request of a Purchaser, will meet with each Purchaser or a representative thereof at the Company’s headquarters during the Company’s normal business hours to discuss all
information relevant for disclosure in the Registration Statement covering the Registrable Securities and will otherwise reasonably cooperate with the Purchasers conducting an investigation for the purpose of reducing or eliminating the
Purchasers’ exposure to liability under the Securities Act, including the reasonable production of information at the Company’s headquarters; provided, that the Company shall not be required to disclose any confidential information to or
meet at its headquarters with a Purchaser until and unless that Purchaser shall have entered into a confidentiality agreement in form and substance reasonably satisfactory to the Company with the Company with respect thereto. 

6.6 Public Statements; Limitation on Information. The Company agrees to (A) issue a press release by 9:00 a.m. (New York
City time) on the business day immediately following the date hereof disclosing the material terms of the Offering and (B) file a Current Report on Form 8-K within the time required by and in accordance
with the requirements of the Exchange Act. Such Current Report on Form 8-K shall include a form of this Agreement (and all exhibits and schedules thereto) as an exhibit thereto. From and after the issuance of
such press release, the Company represents to the Purchasers that it shall have publicly disclosed all material, non-public information delivered to any of the Purchasers by the Company or any of its

  
 Page 29 

 
subsidiaries, or any of their respective officers, directors, employees or agents in connection with the Offering. The Company will not issue any public statement, press release or any other
public disclosure listing a Purchaser as one of the purchasers of the Shares without that Purchaser’s prior written consent, except as may be required by applicable law or regulation or rules of any exchange on which the Company’s
securities are listed. The Company shall not provide, and shall cause each of its subsidiaries and the respective officers, directors, employees and agents of the Company and each of its subsidiaries not to provide, the Purchasers with any material
nonpublic information regarding the Company or any subsidiary from and after the date the Company files, or is required by this Section to file, the Current Report on Form 8-K with the SEC without the prior
express written consent of the Purchaser. 
 6.7 Limits on Additional Issuances. Without limiting the provisions of
Section 5.6, the Company will not, for a period of six months following the Closing Date offer for sale or sell any securities unless, in the opinion of the Company’s counsel, such offer or sale does not jeopardize the availability of
exemptions from the registration and qualification requirements under applicable securities laws with respect to the Offering. Except for the issuance of equity awards under the Company’s equity incentive plans, the issuance of Common Stock
upon exercise of outstanding options and warrants, the issuance of Common Stock purchase warrants, and the offering contemplated hereby, the Company has not engaged in any offering of equity securities during the six months prior to the date of this
Agreement. The foregoing provisions shall not prevent the Company from filing a “shelf” registration statement pursuant to Rule 415 under the Securities Act, but the foregoing provisions shall apply to any sale of securities thereunder.

 6.8 Form D and State Securities Filings. The Company will file with the SEC a Notice of Sale of Securities on Form D with
respect to the Shares, as required under Regulation D under the Securities Act, no later than 15 days after the Closing Date. The Company will promptly and timely file all documents and pay all filing fees required by any states’ securities
laws in connection with the sale of Shares. 
 6.9 Assignment of Registration Rights. The rights to cause the Company to
register Registrable Securities pursuant to this Section 6 may be assigned by a Purchaser to a party that acquires, other than pursuant to the Registration Statement or Rule 144, any of the Registrable Securities. Any such permitted assignee
shall have all the rights of such Purchaser under this Section 6 with respect to the Registrable Securities transferred. 
 6.10
Selling Stockholder Questionnaire. As a condition to the inclusion of its Registrable Securities in the Registration Statement, each Purchaser shall furnish to the Company such information regarding such Purchaser and the distribution
proposed by such Purchaser as the Company may reasonably request in writing, including furnishing to the Company a completed questionnaire in the form attached to this Agreement as Exhibit B (a “Selling Holder
Questionnaire”). The Company shall not be required to include the Registrable Securities of a Purchaser in a Registration Statement and shall not be required to pay any liquidated or other damages hereunder to any such Purchaser who fails
to furnish to the Company a fully completed Selling Holder Questionnaire at least three business days prior to the filing of the Registration Statement. 

6.11 Short Sales and Confidentiality After The Date Hereof. Each Purchaser, severally and not jointly with the other Purchasers,
covenants that neither it, nor any affiliate 

  
 Page 30 

 
acting on its behalf or pursuant to any understanding with it will execute any purchases or sales, including Short Sales, of any of the Company’s securities during the period commencing with
the Discussion Time and ending at such time the transactions contemplated by this Agreement are first publicly announced. Each Purchaser, severally and not jointly with the other Purchasers, covenants that until such time as the transactions
contemplated by this Agreement are publicly disclosed by the Company, such Purchaser will maintain the confidentiality of the existence and terms of this transaction and any material non-public information
provided to the Purchaser. Notwithstanding the foregoing, and notwithstanding anything contained in this Agreement to the contrary, the Company expressly acknowledges and agrees that (i) no Purchaser makes any representation, warranty or
covenant hereby that it will not engage in effecting transactions in any securities of the Company after the time that the transactions contemplated by this Agreement are first publicly announced, (ii) no Purchaser shall be restricted or
prohibited from effecting any transactions in any securities of the Company in accordance with applicable securities laws from and after the time that the transactions contemplated by this Agreement are first publicly announced and (iii) no
Purchaser shall have any duty of confidentiality to the Company or its subsidiaries with respect to the transactions contemplated by this Agreement after the issuance of the press release described in Section 6.6. Notwithstanding the foregoing,
in the case of a Purchaser that is a multi-managed investment vehicle whereby separate portfolio managers manage separate portions of such Purchaser’s assets and the portfolio managers have no direct knowledge of the investment decisions made
by the portfolio managers managing other portions of such Purchaser’s assets, the covenant set forth above shall only apply with respect to the portion of assets managed by the portfolio manager that made the investment decision to purchase the
securities covered by this Agreement. 
 7. Miscellaneous. 

7.1 Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of New York,
without regard to the choice of law provisions thereof, and the federal laws of the United States. 
 7.2 Successors and Assigns.

parties hereto and their respective successors and assigns, any rights, remedies, obligations, or liabilities under or by reason of this Agreement, except as expressly provided herein. 

7.4 Severability. In the event any provision of this Agreement shall be invalid, illegal, or unenforceable, it shall to the

affected or impaired thereby.

Agreement may be amended and the observance of any term of this Agreement may be waived (either generally or in a particular instance, either retroactively or prospectively, and either for a specified period of time or indefinitely), with the
written consent of the Company and the Purchasers holding Shares that constitute at least a majority of the Shares then held by the Purchasers. Any amendment or waiver effected in accordance with this Section 7.5 shall be binding upon any

 7.6 Fees and
Expenses. Except as otherwise set forth herein, the Company and the Purchasers shall bear their own expenses and legal fees incurred on their behalf with respect to this Agreement and the transactions contemplated hereby. Each party hereby

liability or asserted liability) for which such indemnifying party or any of its employees or representatives are responsible.

investigation made by any party to this Agreement or by the Placement Agent, all covenants, agreements, representations and warranties made by the Company and the Purchasers herein shall survive the execution of this Agreement, the delivery to the

7.9 Counterparts. This Agreement may be executed by facsimile signature and in any number of counterparts, each of which shall

 7.10 Independent Nature of Purchasers’
Obligations and Rights. The obligations of each Purchaser under this Agreement are several and not joint with the obligations of any other Purchaser, and no Purchaser shall be responsible in any way for the performance of the obligations of any
other Purchaser under this Agreement. Nothing contained herein, and no action taken by any Purchaser pursuant hereto, shall be deemed to constitute the Purchasers as a partnership, an association, a joint venture or any other kind of entity, or
create a presumption that the Purchasers are in any way acting in concert or as a group with respect to such obligations or the transactions contemplated by this Agreement. Each Purchaser confirms that it has independently participated in the

SELLING STOCKHOLDER QUESTIONNAIRE 

MATTERSIGHT CORPORATION 

The following information is requested from the entity you represent for the preparation and filing by MATTERSIGHT
CORPORATION (the “Company”) of a Registration Statement (the “Registration Statement”) with the Securities and
Exchange Commission (the “SEC”) covering the resale of the shares of the Company’s common stock (the “Shares”) purchased by the entity and
other purchasers (collectively referred to as the “Selling Stockholders”) pursuant to a Common Stock Purchase Agreement dated in February 2017 (the
“Financing”). Under SEC rules, the Company must disclose in the Registration Statement all of the shares of the Company’s stock that the Selling Stockholders “beneficially own”
(please see the definition of beneficial ownership on Appendix A of this questionnaire). Thus, this questionnaire inquires as to the entity’s beneficial ownership of the Company’s securities, regardless of the
manner in which it was acquired. 
 Please keep in mind that, throughout the questionnaire, the “Company” refers to Mattersight
Corporation and any of its subsidiaries. If information is provided with respect to a subsidiary of the Company, please so indicate. 

Even if the entity does not own any shares of common stock or other securities of the Company other than the Shares that it received in
connection with the Financing, please read the questionnaire carefully and fill out the questionnaire in its entirety (responding zero or not applicable, where appropriate). The definitions of all bolded, italicized terms used in
this questionnaire are set forth at the end of this questionnaire. Please return this questionnaire to, or if you should you have any questions concerning any part of the questionnaire please contact, Nathan Jeffries at Cooley LLP; Phone –
(720) 206-7602; Email – njeffries@cooley.com. 
 * * * * * * * * * 

 

	A.	GENERAL INFORMATION 

 Please provide the entity’s
complete business address, including email address and the name of the contact person: 
  

 
  

 
  

 

  
 Page B-1 

	B.	SECURITIES HOLDINGS 

  

	 	B.1.	Please fill in all blanks in the following questions related to the entity’s beneficial ownership of the Company’s securities. Generally, the term “beneficial
ownership” refers to any direct or indirect interest in the securities which entitles the entity to any of the rights or benefits of ownership, even though it may not be the holder of record of the securities. For example, securities
held in “street name” over which the entity exercises voting or investment power would be considered beneficially owned by it. 

If the entity has any reason to believe that any interest in securities of the Company which it may have, however remote, is a beneficial
interest, please describe such interest. For purposes of responding to this questionnaire, it is preferable to err on the side of inclusion rather than exclusion. Where the SEC’s interpretation of beneficial ownership would
require disclosure of the entity’s interest or possible interest in certain securities of the Company, and you believe that it does not actually possess the attributes of beneficial ownership, an appropriate response is to
disclose the interest and at the same time disclaim beneficial ownership of the securities. 
  

	 	(a)	As of the date hereof, the entity owned outright (including shares registered in its name individually or jointly with others, shares held in the name of a bank, broker, nominee, depository or in “street
name” for its account),                     shares of the Company’s common stock and ) and
                        shares of the Company’s preferred stock. 

 

	 	(b)	In addition to the number of shares the entity owns outright as indicated by the answer to question B.1(a), of the date hereof, it had or shared voting power or investment power, directly or indirectly, through a
contract, arrangement, understanding, relationship or otherwise (e.g., shares subject to a written voting or investment arrangement, or shares held by a corporate benefit plan over which it exercises control), over
                    shares of the Company’s common stock and ),
                     shares of the Company’s preferred stock (none indicated by “0” above). With respect to those shares, provide the
following information: 

 (i) Number of shares of common stock with sole voting power:
                     
 (ii)
Number of shares of preferred stock with sole voting power:                      

  
 Page B-2 

 (iii) Number of shares with shared voting power; with whom shared; and the nature of the
relationship and any underlying voting trust agreement, investment arrangement or the like:

	  	Number of shares	 	  	With whom shared	 	  	Nature of relationship	 
		  				  				  			
		  				  				  			
		  				  				  			

 (iv) Number of shares of common stock with sole investment power:
                     
 (v) Number
of shares of preferred stock with sole investment power:                      

(vi) Number of shares with shared investment power; with whom that power is shared; and the nature of the relationship and any
underlying voting trust agreement, investment arrangement or the like:

	  	Number of shares	 	  	With whom shared	 	  	Nature of relationship	 
		  				  				  			
		  				  				  			
		  				  				  			

  

	 	(c)	Beginning sixty days after the date hereof, the entity will have the right to acquire directly
                     shares of the Company’s common stock and
                     shares of the Company’s preferred stock, including, but not limited to, any right to acquire shares
(i) upon the exercise of any option, warrant or right; (ii) upon conversion of a security; (iii) pursuant to the power to revoke a trust, discretionary account or similar arrangement; or (iv) pursuant to the
automatic termination of a trust (none, indicated by “0” above). 

  

	 	(d)	Beginning sixty days after the date hereof, the entity will have the right to acquire indirectly, or to acquire “voting power” and/or “investment power” with respect to,
                     shares of the Company’s common stock and
                     shares of the Company’s preferred stock, including, but not limited to, any right to acquire shares

	E.	GENERAL 

 The regulations of the SEC require that, if otherwise
disclosable, the information the entity has furnished in response to the questions above be included in the Registration Statement. If you know of any additional information necessary to make the answers you have given on behalf of the entity above
not misleading in the light of the circumstances under which your answers were made, please furnish below: 
  

 
  

 
  

 

  
 Page B-5 

 The undersigned agrees to promptly notify the Company of any inaccuracies or changes in the
information provided herein that may occur subsequent to the date hereof and prior to the effective date of any applicable resale Registration Statement. All notices hereunder and pursuant to the Common Stock Purchase Agreement shall be made in
writing, by hand delivery, confirmed or facsimile transmission, first-class mail or air courier guaranteeing overnight delivery at the address set forth below. In the absence of any such notification, the Company shall be entitled to continue to
rely on the accuracy of the information in this Questionnaire. 
 By signing below, the undersigned consents to the disclosure of the
information contained herein in its answers to Items A through E above and the inclusion of such information in the resale Registration Statement and the related prospectus. The undersigned understands that such information will be relied upon by
the Company in connection with the preparation or amendment of any such Registration Statement and prospectus. 
 By signing below, the
undersigned consents to and agrees to comply with the “Plan of Distribution” attached hereto as Appendix B, which substantively reflect the “Plan of Distribution” to be included in the Registration Statement. 

By signing below, the undersigned acknowledges that it understands its obligation to comply, and agrees that it will comply, with the
provisions of the Securities Exchange Act of 1934, as amended, and the rules and regulations thereunder, particularly Regulation M in connection with any offering of Registrable Securities pursuant to the resale Registration Statement. The
undersigned also acknowledges that it understands that the answers to this Questionnaire are furnished for use in connection with Registration Statements filed pursuant to the Common Stock Purchase Agreement and any amendments or supplements thereto
filed with the Commission pursuant to the Securities Act of 1933, as amended. 
 The undersigned hereby acknowledges and is advised of the
following Interpretation A.65 of the July 1997 SEC Manual of Publicly Available Telephone Interpretations regarding short selling: 

“An Issuer filed a Form S-3 registration statement for a secondary offering of common stock which
is not yet effective. One of the selling stockholders wanted to do a short sale of common stock “against the box” and cover the short sale with registered shares after the effective date. The issuer was advised that the short sale could
not be made before the registration statement become effective, because the shares underlying the short sale are deemed to be sold at the time such sale is made. There would, therefore, be a violation of Section 5 if the shares were effectively
sold prior to the effective date.” 
 By returning this Questionnaire, the undersigned will be deemed to be aware of the foregoing
interpretation. 
 I confirm that, to the best of my knowledge and belief, the foregoing statements (including without limitation the
answers to this Questionnaire) are correct.

authority duly given, has caused this Questionnaire to be executed and delivered either in person or by its duly authorized agent.

 APPENDIX B 

TO EXHIBIT B 

PLAN OF DISTRIBUTION 
 We
are registering for resale by the selling stockholders and certain transferees a total of                      shares of Common Stock. We will not
receive any of the proceeds from the sale by the selling stockholders of the shares of common stock. We will bear all fees and expenses incident to our obligation to register the shares of Common Stock. If the shares of Common Stock are sold through
broker-dealers or agents, the selling stockholder will be responsible for any compensation to such broker-dealers or agents. 
 The selling
stockholders may pledge or grant a security interest in some or all of the shares of Common Stock owned by them and, if they default in the performance of their secured obligations, the pledgees or secured parties may offer and sell the shares of
Common Stock from time to time pursuant to this prospectus. 
 The selling stockholders also may transfer and donate the shares of Common
Stock in other circumstances in which case the transferees, donees, pledgees, or other successors in interest will be the selling beneficial owners for purposes of this prospectus. 

The selling stockholders will sell their shares of Common Stock subject to the following: 

 

	 	•	 	all of a portion of the shares of Common Stock beneficially owned by the selling stockholders or their perspective pledgees, donees, transferees or successors in interest, may be sold on the OTC Bulletin Board Market,
any national securities exchange or quotation service on which the shares of our Common Stock may be listed or quoted at the time of sale, in the over-the counter market, in privately negotiated transactions,
through the writing of options, whether such options are listed on an options exchange or otherwise, short sales or in a combination of such transactions; 

  

	 	•	 	each sale may be made at market price prevailing at the time of such sale, at negotiated prices, at fixed prices or at carrying prices determined at the time of sale; 

 

	 	•	 	some or all of the shares of Common Stock may be sold through one or more broker-dealers or agents and may involve crosses, block transactions or hedging transactions. The selling stockholders may enter into hedging
transactions with broker-dealers or agents, which may in turn engage in short sales of the Common Stock in the course of hedging in positions they assume. The selling stockholders may also sell shares of Common Stock short and deliver shares of
Common Stock to close out short positions or loan or pledge shares of Common Stock to broker-dealers or agents that in turn may sell such shares; and 

  

	 	•	 	 in connection with such sales through one or more broker-dealers or agents, such broker-dealers or agents may
receive compensation in the form of discounts, concessions or commissions from the selling stockholders and may receive commissions from the purchasers of the shares of Common Stock for whom they act as broker-dealer or agent or to whom they sell as
principal (which discounts, concessions or commissions as to particular broker-dealers or agents may be in 

  
 Page B-8 

	 	 
excess of those customary in the types of transaction involved). Any broker-dealer or agent participating in any such sale may be deemed to be an “underwriter” within the meaning of the
Securities Act and will be required to deliver a copy of this prospectus to any person who purchases any share of Common Stock from or through such broker-dealer or agent. We have been advised that, as of the date hereof, none of the selling
stockholders have made any arrangements with any broker-dealer or agent for the sale of their shares of common stock. 

The selling stockholder and any broker-dealer participating in the distribution of the shares of Common Stock may be deemed to be
“underwriters” within the meaning of the Securities Act, and any profits realized by the selling stockholders and any commissions paid, or any discounts or concessions allowed to any such broker-dealer may be deemed to be underwriting
commissions or discounts under the Securities Act. In addition, any shares of Common Stock covered by this prospectus which qualify for sale pursuant to Rule 144 may be sold under Rule 144 rather than pursuant to this prospectus. A selling
stockholder may also transfer, devise or gift the shares of Common Stock by other means not covered in this prospectus in which case the transferee, devisee, or giftee will be the selling stockholder under this prospectus. 

If required at the time a particular offering of the shares of Common Stock is made, a prospectus supplement or, if appropriate, a
post-effective amendment to the shelf registration statements of which this prospectus is a part, will be distributed which will set forth the aggregate amount of shares of Common Stock being offered and the terms of the offering, including the name
or names of any broker-deals or agents, any discounts, commissions or concessions allowed or reallowed or paid to broker-dealers. 
 Under
the securities laws of some states, the shares of Common Stock may be sold in such states only through registered or licensed brokers or dealers. In addition, in some states the shares of Common Stock may not be sold unless such shares have been
registered or qualified for sale in such state or an exemption from registration or qualification is available and is complied with. There can be no assurance that any selling stockholder will sell any or all of the shares of Common Stock registered
pursuant to the shelf registration statement, of which this prospectus forms a part. 
 The selling stockholders and any other person
participating in such distribution will be subject to applicable provisions of the Exchange Act and the rules and regulations thereunder, including, without limitation, Regulation M of the Exchange Act, which may limit the timing of purchases and
sales of any of the shares of Common Stock by the selling stockholders and any other participating person. Regulation M may also restrict the ability of any person engaged in the distribution of the shares of Common Stock to engage in market-making
activities with respect to the shares of Common Stock. All of the foregoing may affect the marketability of the shares of Common Stock and the ability of any person or entity to engage in market-making activities with respect to the shares of Common
Stock. 
 We will bear all expenses of the registration of the shares of Common Stock including, without limitation, Securities and Exchange
Commission filing fees and expenses of compliance with the state securities of “blue sky” laws. The selling stockholders will pay all underwriting discounts and selling commissions and expenses, brokerage fees and transfer taxes, as well
as the 

  
 Page B-9 

 
fees and disbursements of counsel to and experts for the selling stockholders, if any. We will indemnify the selling stockholders against liabilities, including some liabilities under the
Securities Act, in accordance with the registration rights agreement or the selling stockholder will be entitled to contribution. We will be indemnified by the selling stockholders against civil liabilities, including liabilities under the
Securities Act that may arise from any written information furnished to us by the selling stockholders for use in this prospectus, in accordance with the related securities purchase agreement or will be entitled to contribution. Once sold under this
shelf registration statement, of which this prospectus forms a part, the shares of Common Stock will be freely tradable in the hands of persons other than our affiliates. 

We have agreed to keep the registration statement that includes this prospectus effective until the earlier of (i) the second anniversary
of the closing under the Purchase Agreement, (ii) the date on which all shares of common stock sold under the Purchase Agreement may be sold pursuant to Rule 144 during any three-month period without the requirement for the Company to be in
compliance with the current public information required under Rule 144(c)(1) or (iii) such time as all shares of common stock sold under the Purchase Agreement have been sold pursuant to a registration statement or Rule 144.

Form of Lock-Up 

Date:                      

Craig-Hallum Capital Group LLC 
 222 South Ninth Street, Suite
350 
 Minneapolis, Minnesota 55402 
 Ladies and Gentlemen:

 Pursuant to Section 4.1(k) of the Common Stock Purchase Agreement, dated February 23, 2017, by and between Mattersight Corporation,
a Delaware corporation (the “Company”), and the parties listed on Exhibit A attached thereto (the “Purchase Agreement”), and as an inducement to Craig-Hallum Capital Group LLC
(“Craig-Hallum”) to act as placement agent for the offering of the Company’s common stock, par value $0.01 per share (the “Common Stock”), pursuant to the Purchase Agreement (the
“Offering”), the undersigned hereby agrees that without, in each case, the prior written consent of Craig-Hallum during the period specified in the second succeeding paragraph (the “Lock-Up Period”), the undersigned will not: (1) offer, pledge, announce the intention to sell, sell, contract to sell, sell any option or contract to purchase, purchase any option or
contract to sell, grant any option, right or warrant to purchase, make any short sale or otherwise transfer or dispose of, directly or indirectly, any shares of the Company’s Common Stock or any securities convertible into, exercisable or
exchangeable for or that represent the right to receive Common Stock (including without limitation, Common Stock which may be deemed to be beneficially owned by the undersigned in accordance with the rules and regulations of the Securities and
Exchange Commission and securities which may be issued upon exercise of a stock option or warrant) whether now owned or hereafter acquired (the “Undersigned’s Securities”); (2) enter into any swap or other
agreement that transfers, in whole or in part, any of the economic consequences of ownership of the Undersigned’s Securities, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of Common Stock or
such other securities, in cash or otherwise; (3) make any demand for or exercise any right with respect to, the registration of any Common Stock or any security convertible into or exercisable or exchangeable for Common Stock; or
(4) publicly disclose the intention to do any of the foregoing. 
 The undersigned agrees that the foregoing restrictions preclude the
undersigned from engaging in any hedging or other transaction which is designed to or which reasonably could be expected to lead to or result in a sale or disposition of the Undersigned’s Securities even if such Undersigned’s Securities
would be disposed of by someone other than the undersigned. Such prohibited hedging or other transactions would include without limitation any short sale or any purchase, sale or grant of any right (including without limitation any put or call
option) with respect to any of the Undersigned’s Securities or with respect to any security that includes, relates to or derives any significant part of its value from such Undersigned’s Securities. 

The initial Lock-Up Period will commence on the date of this Agreement and continue through and
include the effective date of the Registration Statement (as defined in the Purchase Agreement). 

  
 Page C-1 

 Notwithstanding the foregoing, the undersigned may transfer the Undersigned’s Securities
(i) as a bona fide gift or gifts, (ii) to any trust for the direct or indirect benefit of the undersigned or the immediate family of the undersigned, (iii) if the undersigned is a corporation, partnership, limited liability company,
trust or other business entity (1) transfers to another corporation, partnership, limited liability company, trust or other business entity that is a direct or indirect affiliate (as defined in Rule 405 promulgated under the Securities Act of
1933, as amended) of the undersigned or (2) distributions of shares of Common Stock or any security convertible into or exercisable for Common Stock to limited partners, limited liability company members or stockholders of the undersigned,
(iv) if the undersigned is a trust, transfers to the beneficiary of such trust, (v) transfers by testate succession or intestate succession, (vi) pursuant to transfers that occur by operation of law pursuant to a qualified domestic
order or in connection with a divorce settlement, (vii) pursuant to transfers or dispositions not involving a change in beneficial ownership or (viii) pursuant to the Purchase Agreement; provided, in the case of clauses (i) through
(vii), that (x) such transfer shall not involve a disposition for value, (y) the transferee agrees in writing with Craig-Hallum to be bound by the terms of this Lock-Up Agreement and (z) no
filing by any party under Section 16(a) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), shall be required or shall be made voluntarily in connection with such transfer. For purposes of this Agreement,
“immediate family” shall mean any relationship by blood, marriage or adoption, nor more remote than first cousin. 
 In addition,
the foregoing restrictions shall not apply to (i) the exercise of stock options granted pursuant to the Company’s equity incentive plans; provided that such restrictions shall apply to any of the Undersigned’s Securities issued upon
such exercise, (ii) transfer shares of Common Stock to the Company to cover tax withholding obligations of the undersigned in connection with the vesting of any stock options, restricted stock or restricted stock unit award granted pursuant to
the Company’s equity incentive plans, provided that the underlying shares of Common Stock shall continue to be subject to the restrictions on transfer set forth in this Agreement, (iii) the transfer of shares of Common Stock or any
security convertible into or exercisable or exchangeable for Common Stock pursuant to a bona fide third-party tender offer, merger, consolidation or other similar transaction that is approved by the board of directors of the Company, made to all
holders of Common Stock involving a Change of Control (as defined below), provided that in the event that the tender offer, merger, consolidation or other such transaction is not completed, the Common Stock owned by the undersigned shall remain
subject to the restrictions contained in this Agreement, or (iv) the establishment of any contract, instruction or plan (a “Plan”) that satisfies all of the requirements of Rule
10b5-1(c)(1)(i)(B) under the Exchange Act; provided that no sales of the Undersigned’s Securities shall be made pursuant to such a Plan prior to the expiration of the
Lock-Up Period, and such a Plan may only be established if no public announcement of the establishment or existence thereof and no filing with the Securities and Exchange Commission or other regulatory
authority in respect thereof or transactions thereunder or contemplated thereby, by the undersigned, the Company or any other person, shall be required, and no such announcement or filing is made voluntarily, by the undersigned, the Company or any
other person, prior to the expiration of the Lock-Up Period. For the purposes of the foregoing clause (iv), “Change of Control” shall mean the transfer (whether by tender offer, merger, consolidation
or other similar transaction), in one transaction or a series of related transactions, to a person or group of affiliated persons, of the Company’s voting securities if, after such transfer, such person or group of affiliated persons would hold
more than 50% of the outstanding voting securities of the Company (or the surviving entity). 

  
 Page C-2 

 In furtherance of the foregoing, the Company and its transfer agent and registrar are hereby
authorized to decline to make any transfer of shares of Common Stock or other Company securities if such transfer would constitute a violation or breach of this Agreement. 

The undersigned hereby represents and warrants that the undersigned has full power and authority to enter into this Agreement and that upon
request, the undersigned will execute any additional documents necessary to ensure the validity or enforcement of this Agreement. All authority herein conferred or agreed to be conferred and any obligations of the undersigned shall be binding upon
the successors, assigns, heirs or personal representatives of the undersigned. 
 The undersigned understands that the undersigned shall be
released from all obligations under this Agreement if (i) the Company notifies Craig-Hallum that it does not intend to proceed with the Offering, (ii) the Purchase Agreement does not become effective, or if the Purchase Agreement (other
than the provisions thereof which survive termination) shall terminate or be terminated prior to payment for and delivery of the Common Stock to be sold thereunder or (iii) the Offering is not completed by April 30, 2017. 

The undersigned understands that Craig-Hallum is proceeding with the Offering in reliance upon this Agreement. 

This Agreement shall be governed by, and construed in accordance with, the laws of the State of New York.
