	 	Re:	Exchange of Private Placement Warrants 

 Gentlemen: 

Reference is made to that certain purchase agreement by and between Hennessy Capital Acquisition Corp. (the “Company”) and The Traxis
Group, B.V. (“Traxis), dated as of the date hereof (the “Purchase Agreement”). In order to induce Traxis to enter into the Purchase Agreement, Hennessy Capital Partners I LLC (“HCPI”) has agreed to enter into this letter
agreement (this “Agreement”) relating to the exchange of a number of warrants sold to HCPI by the Company in a private placement in connection with the Company’s initial public offering (the “Private Placement Warrants”)
equal to (i) 12,125,000 less (ii) the number of public warrants validly tendered and not withdrawn in the Warrant Exchange Offer for shares of common stock (“Common Stock”) of the Company. For purposes of this letter, the term
“Exchange Private Placement Warrants” shall refer solely to the Private Placement Warrants to be exchanged pursuant to the immediately preceding sentence and “Exchange Shares” shall refer to any shares of Common Stock of the
Company to be issued to HCPI pursuant to this Agreement. Capitalized terms used and not otherwise defined herein are defined in the Purchase Agreement and shall have the meanings given to such terms in the Purchase Agreement. 

HCPI and the Company hereby agree with Traxis as follows: 

1. If the Warrant Exchange Offer is consummated prior to the Closing Date, then at the Closing HCPI shall exchange each Exchange Private
Placement Warrant for 0.10 shares of Common Stock, resulting in the issuance to HCPI of up to 1,212,500 shares of Common Stock. In order to effectuate such exchange, upon the Closing, HCPI shall deliver its original Private Placement Warrants to the
Company against delivery of a stock certificate for the Exchange Shares and the Company shall return to HCPI a replacement Private Placement Warrant representing the difference, if any, between the 12,125,000 Private Placement Warrants initially
issued to HCPI and the number of Exchange Private Placement Warrants to be exchanged pursuant to this paragraph 1. The Company agrees that the registration rights granted to HCPI with respect to the Exchange Private Placement Warrants shall continue
with respect to the Exchange Shares to be issued to HCPI hereunder. 
 2. If, however, the Warrant Exchange Offer has not been consummated
prior to the Closing Date, then the following shall occur: 
 a. At the Closing, HCPI shall deliver to the Company its
original Private Placement Warrants. Each of 6,375,000 of such Private Placement Warrants shall be exchanged at the Closing for 0.10 shares of Common Stock, resulting in the issuance to HCPI of 637,500 shares of Common Stock. 

  
 1 

 b. In addition, if the Warrant Exchange Offer is consummated during the period
commencing on the Closing Date and ending on the 15th calendar day following the Closing Date (such date of consummation, if any, the “Post-Closing Warrant Exchange Offer Closing Date” and such 15th calendar day, the “Outside
Date”), then the Company (and HCPI, if so directed by the Company) shall direct the Company’s transfer agent (or such other intermediaries as appropriate) to take such actions, and HCPI shall take such actions, as are necessary to cause
the exchange by HCPI of, and HCPI shall so exchange, an additional amount of Private Placement Warrants equal to (i) 5,750,000 less (ii) the number of public warrants validly tendered and not withdrawn in the Warrant Exchange Offer for
0.10 shares of Common Stock, resulting in the issuance to HCPI of up to an additional 575,00 shares of Common Stock. In order to effectuate such exchange on the Post-Closing Warrant Exchange Offer Closing Date, if any, the Company shall return to
HCPI a replacement Private Placement Warrant representing the difference, if any, between the 12,125,000 Private Placement Warrants initially issued to HCPI and the total number of Exchange Private Placement Warrants exchanged pursuant to paragraphs
2(a) and 2(b) of this Agreement; provided, however, that, notwithstanding anything to the contrary in this paragraph 2(b), if the Warrant Exchange Offer has not been consummated on or prior to the Outside Date, then the Company (and HCPI, if so
directed by the Company) shall direct the transfer agent (or such other intermediaries as appropriate) to take such actions, and HCPI shall take such actions, as are necessary to cause the exchange by HCPI of, and HCPI shall so exchange, all
outstanding Private Placement Warrants on the Business Day immediately following the Outside Date, for 0.10 shares of Common Stock, resulting in the issuance to HCPI of an additional 575,000 shares of Common Stock. 

3. In furtherance, and not in limitation of, any other restrictions applicable to the Private Placement Warrants, whether pursuant to the
terms of any such Private Placement Warrant or otherwise, no Private Placement Warrants shall be exercised by HCPI prior to the second Business Day following the Outside Date. 

4. From the Closing Date until the earliest of: (a) the 180th day after the Closing Date, (b) the date following the Closing Date on
which the Company completes a liquidation, merger, stock exchange or other similar transaction that results in all of the Company’s stockholders having the right to exchange their shares of Common Stock for cash, securities or other property
and (c) if the last sale price of the Company’s common stock equals or exceeds $12.00 per share (as adjusted for stock splits, stocks dividends, reorganizations, recapitalizations and the like) for any 20 trading days within any 30-trading
day period commencing at least 150 days after the Business Combination, the close of business on such 20th trading day ( such 20th trading day, the “Alternative Lock-up Termination
Date”) (the period from the Closing Date until the earliest of clause (a), (b) and (c), the “Lock-Up Period”), it will not: (i) sell, offer to sell, contract or agree to sell, hypothecate, pledge, grant any option to
purchase or otherwise dispose of or agree to dispose of, directly or indirectly, or establish or increase a put equivalent position or liquidate or decrease a call equivalent position within the meaning of Section 16 of the Securities Exchange
Act of 1934, as amended, and the rules and regulations of the Securities and Exchange Commission promulgated thereunder, with respect to the Exchange Shares , any shares of Common Stock issuable pursuant to those Private Placement Warrants that do
not constitute Exchange Private Placement Warrants or the Founder Earnout Shares (as defined in the letter agreement, dated January 16, 2014, between HCPI and the Company), (ii) enter into any swap or other arrangement that transfers to
another, in whole or in part, any of the economic consequences of ownership of any of the Exchange Shares , any shares of Common Stock issuable pursuant to those Private Placement Warrants that do not constitute Exchange Private Placement Warrants
or the Founder Earnout Shares, in cash or otherwise, or (iii) publicly announce any intention to effect any transaction specified in clause (i) or (ii).

 5. The undersigned hereby authorizes the Company during the Lock-Up Period to cause its transfer
agent for the Exchange Shares , any shares of Common Stock issuable pursuant to those Private Placement Warrants that do not constitute Exchange Private Placement Warrants and the Founder Earnout Shares to decline to transfer, and to note stop
transfer restrictions on the stock register and other records relating to, the Exchange Shares , any shares of Common Stock issuable pursuant to those Private Placement Warrants that do not constitute Exchange Private Placement Warrants and the
Founder Earnout Shares for which the undersigned is the record holder and, in the case of the Exchange Shares , any shares of Common Stock issuable pursuant to those Private Placement Warrants that do not constitute Exchange Private Placement
Warrants and the Founder Earnout Shares for which the undersigned is the beneficial but not the record holder, agrees during the Lock-Up Period to cause the record holder to cause the relevant transfer agent to decline to transfer, and to note stop
transfer restrictions on the stock register and other records relating to, such Exchange Shares , any shares of Common Stock issuable pursuant to those Private Placement Warrants that do not constitute Exchange Private Placement Warrants and the
Founder Earnout Shares, if such transfer would constitute a violation or breach of this Agreement. 
 6. Notwithstanding the foregoing, HCPI
may sell or otherwise transfer all or a portion of the Exchange Shares, any shares of Common Stock issuable pursuant to those Private Placement Warrants that do not constitute Exchange Private Placement Warrants or the Founder Earnout Shares to:
(i) its direct or indirect equity holders or to any of its other affiliates (as defined in Regulation C of the Securities Act of 1933, as amended), (ii) the immediate family members (including spouses, significant others, lineal
descendants, brothers and sisters) of its direct or indirect equity holders or any of its other affiliates, (iii) a family trust, foundation or partnership established for the exclusive benefit of HCPI, its direct or indirect equity holders,
any of its affiliates or any of their respective immediate family members or (iv) a charitable foundation controlled by HCPI, its direct or indirect equity holders, any of its affiliates or any of their respective immediate family members,
provided in each such case that the transferee thereof enters into a written agreement to be bound by the restrictions set forth herein. 

7. This Agreement constitutes the entire agreement and understanding of the parties hereto in respect of the subject matter hereof and
supersedes all prior understandings, agreements, or representations by or among the parties hereto, written or oral, to the extent they relate in any way to the subject matter hereof. This Agreement may not be changed, amended, modified or waived
(other than to correct a typographical error) as to any particular provision, except by a written instrument executed by all parties hereto. 

8. No party hereto may assign either this Agreement or any of its rights, interests, or obligations hereunder without the prior written
consent of the other party. Any purported assignment in violation of this paragraph shall be void and ineffectual and shall not operate to transfer or assign any interest or title to the purported assignee. This Agreement shall be binding on the
undersigned and their respective successors and assigns. 
 9. This Agreement shall be governed by and construed and enforced in accordance
with the laws of the State of Delaware, without giving effect to conflicts of law principles that would result in the application of the substantive laws of another jurisdiction. The parties hereto (i) all agree that any action, proceeding,
claim or dispute arising out of, or relating in any way to, this Agreement shall be brought and enforced in the Court of Chancery of the State of Delaware (or, if the Court of Chancery of the State of Delaware lacks jurisdiction, then in the
applicable Delaware state court), or if under applicable Law exclusive jurisdiction of such action is vested in the federal courts, then the United States District Court for the District of Delaware, and irrevocably submits to such jurisdiction and
venue, which jurisdiction and venue shall be 

  
 3

the Securities Act, covering all or any part of its Registrable Securities, by delivering a written notice thereof to the Company specifying the number of Registrable Securities to be included in such registration and the intended method of

(i) more than an aggregate of ten (10) Demand Registrations under this Section 2.01 with respect to any or all of the Registrable Securities held by Traxis or its Transferees and (ii) a Demand Registration at any time that Traxis
and its Transferees owns Registrable Securities that represent less than 7.5% of the Outstanding Common Stock. In all instances, the Demanding Party and the Company shall cooperate in good faith regarding a Demand Registration Request should the
Company have any planned offering(s), or if the Company has effected an offering of its Equity Interests (other than pursuant to a Registration Statement on Form S-8), within six months of the delivery of such Demand Registration Request.

 (b)The Company shall use its reasonable best efforts to include in the Demand Registration the
Registrable Securities requested to be included therein by the Demanding Party and by any other Holders of Registrable Securities issued to Traxis pursuant to the Purchase Agreement that shall have made a written request to the Company for inclusion
in such registration (which request shall specify the maximum number of Registrable Securities intended to be disposed of by such other Holder) within 30 days after the receipt of the Demand Exercise Notice. 

(c) The Company shall use its reasonable best efforts to (i) effect the registration under the Securities Act (including by means of a
shelf registration pursuant to Rule 415 under the Securities Act if so requested by the Demanding Party and if the Company is then eligible to effect such a registration on Form S-3 or on any successor to Form S-3) of the Registrable Securities
which the Company has been so requested to register by the Demanding Party and the other Holders of Registrable Securities issued to Traxis pursuant to the Purchase Agreement (to the extent permitted to be registered in accordance with the terms
hereof), for distribution in accordance with the intended method of distribution described in the Demand Registration Request, and (ii) if requested by the Demanding Party, obtain acceleration of the effective date of the Registration Statement
relating to such registration. 
 (d) If a requested registration pursuant to this Section 2.01 involves an underwritten offering, the
Demanding Party shall have the right to select an investment banker or bankers of nationally recognized standing to administer the offering; provided, however, that such investment banker or bankers shall be reasonably satisfactory to the Company.
The Company shall notify the Demanding Party if the Company objects to any investment banker or manager selected by the Demanding Party pursuant to this Section 2.01(d) within ten (10) Business Days after the Demanding Party has notified
the Company of such selection. 
 (e) Notwithstanding anything to the contrary in this Section 2.01: 

(i) If the managing underwriter of any underwritten Public Offering shall advise the Demanding Party that the Registrable
Securities covered by the Registration Statement cannot be sold in such offering within a price range acceptable to the Demanding Party, then the Demanding Party shall have the right to notify the Company that it has determined that the Registration
Statement be abandoned or withdrawn with respect to its Registrable Securities, in which event the Company shall abandon or withdraw such Registration Statement and notify all other Holders participating in such Demand Registration. 

(ii) If a majority of the Board determines in good faith that a Disadvantageous Condition exists, the Company shall,
notwithstanding any other provision of this Article II, be entitled, upon the giving of a written notice (a “Delay Notice”) to such effect to each Holder of Registrable Securities included or to be

  
 -6- 

 
included in such Registration Statement, to delay the filing of such Registration Statement until, in the judgment of a majority of Board, such Disadvantageous Condition no longer exists (notice
of which the Company shall promptly deliver to the Holders of the Registrable Securities with respect to which any such Registration Statement was to have been filed); provided, however, that such delay shall not exceed a period of
one-hundred twenty (120) days from the date on which the Demand Registration Request is received by the Company; and provided, further, that the Company shall not exercise its right to delay the filing of any Registration
Statement unless such delay is also applied to any other holder of registration rights. 
 (f) In connection with any Demand Registration
Request involving an underwritten offering, if the managing underwriter shall advise the Company that, in its view, the number of securities (including the Registrable Securities) that the Holders, the Company and any other Person intend to include
in such registration exceeds the largest number of securities which can be sold in such offering at a price reasonably acceptable to the Demanding Party (the “Demand Registration Maximum Offering Size”), then the Company will
include in such registration, in the following priority, up to the Demand Registration Maximum Offering Size: 
 (i) first,
the Registrable Securities requested to be included in such registration pursuant to this Section 2.01; if the number of Registrable Securities requested to be included exceeds the Demand Registration Maximum Offering Size, then the Registrable
Securities to be included in such registration shall be allocated pro rata among the Holders requesting registration based on the number of securities duly requested to be included in such registration by each such Holder; and 

(ii) second, the Underlying Common Shares, the Backstop Shares and the Utilization Fee Shares requested to be registered
pursuant to Section 2.02; if the Underlying Common Shares, the Backstop Shares and the Utilization Fee Shares, together with the Registrable Securities requested to be included in such registration pursuant to this Section 2.01, exceed the
Demand Registration Maximum Offering Size, then the Underlying Common Shares, the Backstop Shares and Utilization Fee Shares to be included in such registration shall be allocated pro rata among the Investors based on the number of Underlying Common
Shares, the Backstop Shares and the Utilization Fee Shares requested to be included in such registration by each Investor; and 

(iii) third, the securities requested to be included in such registration by the Pre-IPO Holders; and 

(iv) fourth, the securities to be offered by the Company; and 

(v) fifth, all other securities requested by any other Person to be included in such registration (pursuant to contractual
registration rights or otherwise). 

  
 -7- 

 (g) Notwithstanding the foregoing, the Company shall not be obligated to effect, or to take any
action to effect, any registration pursuant to this Section 2.01 with respect to the Registrable Securities during the period starting with the date 30 days prior to the Company’s good faith estimate of the date of filing of, and ending on
a date 180 days after the effective date of, a registration subject to Section 2.02 hereof. 
 (h) The Company shall not have any
obligation hereunder to register any Registrable Securities under this Section 2.01 unless it shall have received requests from a Demanding Party to register shares of Common Stock having an aggregate market valuation, based on the most recent
closing price of the Common Stock at the time of the demand, of $20.0 million. 
 (i) No registration of Registrable Securities under this
Section 2.01 shall relieve the Company of its obligations (if any) to effect registrations of Registrable Securities pursuant to Section 2.02 or Section 2.12. 

Section 2.02 Piggyback Registration Rights.  

(a)At any time following the Effective Date, if the Company proposes to register (whether proposed to be offered for sale by the Company or by
any other Person) any shares of capital stock (collectively, the “Other Securities”) under the Securities Act on a form and in a manner that would permit registration of the Registrable Securities for sale to the public under the
Securities Act, each Holder of Registrable Securities will have the right to include its Registrable Securities in such registration in accordance with this Section 2.02. The Company will give prompt written notice to all Holders of Registrable
Securities of its intention to register the Other Securities, describing the number of shares to be registered for sale and specifying the form and manner and the other relevant facts involved in such proposed registration (including, without
limitation, whether or not such registration will be in connection with an underwritten offering, and if so, the identity of the managing underwriter and whether such offering will be pursuant to a “best efforts” or “firm
commitment” underwriting). Upon the written request of any Holder delivered to the Company within 15 days after such notice shall have been received by such Holder (which request shall specify the maximum number of Registrable Securities
intended to be disposed of by such Holder and shall confirm that such Holder will dispose of such Registrable Securities pursuant to the Company’s intended method of disposition), the Company will use its reasonable best efforts to effect the
registration under the Securities Act of all Registrable Securities that the Company has been so requested to register by the Holders of such Registrable Securities; provided, however, that: 

(i) if such registration involves an underwritten offering, all Holders requesting that their Registrable Securities be
included in such registration must sell their Registrable Securities to the underwriters selected by the Company (and/or such other Person offering the Other Securities) on the same terms and conditions as the terms and conditions that apply to the
Company (and/or such other Person(s) offering the Other Securities); and 

  
 -8- 

 (ii) if, at any time after giving such written notice of its intention to
register any of such Registrable Securities for sale, and prior to the effective date of the Registration Statement filed in connection with such registration, the Company shall determine for any reason to withdraw such Registration Statement, the
Company may, at its election, give written notice of such determination to each Holder that has requested to register Registrable Securities and thereupon the Company shall be relieved of its obligation to register any Registrable Securities in
connection with such registration; provided, however, that all Registration Expenses of such withdrawn registration shall be borne by the Company in accordance with Section 2.03 hereof. 

(b) In connection with any Public Offering with respect to which Holders shall have requested registration pursuant to this Section 2.02,
if the managing underwriter shall advise the Company that, in its view, the number of securities (including the Registrable Securities) that the Company, the Holders and any other Person intend to include in such registration exceeds the largest
number of securities which can be sold without having an adverse effect on such offering, including the price at which such securities can be sold (the “Piggyback Registration Maximum Offering Size”), the Company will include in
such registration, in the following priority, up to the Piggyback Registration Maximum Offering Size: 
 (i) first, all the
Other Securities that the Company proposes to include in such registration; 
 (ii) second, the Underlying Common Shares, the
Backstop Shares and the Utilization Fee Shares requested to be registered pursuant to this Section 2.02; if the Underlying Common Shares, the Backstop Shares and the Utilization Fee Shares, together with all the Other Securities that the
Company proposes to include in such registration, exceed the Piggyback Registration Maximum Offering Size, then the Underlying Common Shares, the Backstop Shares and the Utilization Fee Shares to be included in such registration shall be allocated
pro rata among the Investors based on the number of Underlying Common Shares, the Backstop Shares and the Utilization Fee Shares requested to be included in such registration by each Investor; 

(iii) third, (A) the other Registrable Securities requested to be registered pursuant to this Section 2.02 and
(B) the Other Securities requested to be registered by the Pre-IPO Holders; if the number of such other Registrable Securities and the Other Securities of the Pre-IPO Holders requested to be included exceeds the Piggyback Registration Maximum
Offering Size, then such other Registrable Securities and the Other Securities of the Pre-IPO Holders to be included in such registration shall be allocated pro rata among the persons requesting registration based on the number of securities duly
requested to be included in such registration by each such person; and 
 (ii) fourth, all Other Securities requested by any
other Person to be included in such registration (pursuant to contractual registration rights or otherwise). 
 (c) If a Holder decides not
to include all of its Registrable Securities in any Registration Statement thereafter filed by the Company, such Holder shall nevertheless continue to have the right to include any Registrable Securities in any subsequent Registration Statement or
Registration Statements as may be filed by the Company with respect to offerings of securities, all upon the terms and conditions set forth herein. 

  
 -9- 

 (d) Notwithstanding anything in this Article II to the contrary, the Company shall not be
required to give notice of, or effect any registration of Registrable Securities under this Article II incidental to, the registration of any of its securities in connection with mergers, consolidations, acquisitions, exchange offers, subscription
offers, dividend reinvestment plans or stock options or other employee benefit or compensation plans. 
 Section 2.03 Registration
Expenses.  
 The Company shall pay all Registration Expenses in connection with the registration of Registrable Securities pursuant to
this Article II. “Registration Expenses” means all expenses incident to the Company’s performance of or compliance with Article II, including, without limitation, all registration, filing and qualification fees (including
filing fees with respect to FINRA), all fees and expenses of complying with state securities or “blue sky” laws (including reasonable fees and disbursements of underwriters’ counsel in connection with any “blue sky”
memorandum or survey), any underwriting discounts, commissions, fees and related expenses, all fees and disbursements of the attorneys-in-fact and the custodian for the Holders, all printing expenses, all listing fees, all registrars’ and
transfer agents’ fees, the fees and disbursements of counsel for the Company and of its independent certified public accountants, including the expenses of any special audits and/or “comfort” letters required by or incident to such
performance and compliance. In addition, in connection with each registration, the Company shall pay the reasonable fees and expenses of one legal counsel to represent the interests of the Holders selling Registrable Securities in such registration.

 Section 2.04 Registration Procedures.  

(a) If and whenever the Company is required to effect the registration of any Registrable Securities under the Securities Act as provided in
this Article II, the Company will: 
 (i) promptly prepare and file with the Commission a Registration Statement with respect
to such Registrable Securities and use its reasonable best efforts to cause such Registration Statement to become effective as soon as reasonably practicable thereafter; 

(ii) prepare and file with the Commission such amendments (including any statutory prospectus, preliminary prospectus or issuer
free writing prospectus or any amendment or supplement) and supplements to such Registration Statement and the Prospectus used in connection therewith as may be necessary to keep such Registration Statement effective and to comply with the
provisions of the Securities Act with respect to the disposition of all Registrable Securities covered by such Registration Statement until the earlier of (a) such time as all such Registrable Securities have been disposed of in accordance with
the intended methods of disposition by the seller or sellers thereof set forth in such Registration Statement, and (b) 210 days from the date such Registration Statement first becomes effective; 

  
 -10- 

 (iii) furnish to each seller of such Registrable Securities such number of
conformed copies of such Registration Statement and of each such amendment and supplement thereto (in each case including all exhibits), such number of copies of the Prospectus included in such Registration Statement, in conformity with the
requirements of the Securities Act, such documents incorporated by reference in such Registration Statement or Prospectus and such other documents as such seller may reasonably request in order to facilitate the sale of such Registrable Securities;

 (iv) register or qualify all Registrable Securities and other securities covered by such Registration Statement under such
securities or “blue sky” laws of such jurisdictions as each seller shall reasonably request, and do any and all other acts and things that may be necessary to enable each such seller to consummate the disposition in such jurisdictions of
its Registrable Securities covered by such Registration Statement, except that the Company shall not for any such purpose be required to qualify generally to do business as a foreign corporation in any jurisdiction wherein it is not so qualified, to
subject itself to taxation in respect of doing business in any such jurisdiction or to consent to general service of process in any such jurisdiction; 

(v) furnish to each seller of Registrable Securities, on the date that the Registrable Securities are delivered to the
underwriters for sale in connection with a Public Offering, (a) an opinion, dated such date, of the counsel representing the Company for the purpose of such registration, in form and substance as is customarily given to underwriters in a Public
Offering, addressed to the underwriters, and (b) a “comfort” letter, dated such date, from the independent certified public accountants of the Company, in form and substance as is customarily given by independent certified public
accountants to underwriters in a Public Offering, addressed to the underwriters; 
 (vi) promptly notify each seller of
Registrable Securities covered by such Registration Statement at any time when a Prospectus relating thereto is required to be delivered under the Securities Act of the happening of any event as a result of which the Prospectus included in such
Registration Statement, as then in effect, includes an untrue statement of a material fact or omits to state any material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances
then existing and if it is necessary to amend or supplement such Prospectus to comply with applicable law, and at the request of any such seller prepare and furnish to such seller a reasonable number of copies of a supplement to or an amendment of
such Prospectus as may be necessary so that, as thereafter delivered to the purchasers of such Registrable Securities, such Prospectus shall not include 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 in the light of the circumstances then existing and shall otherwise comply in all material respects with applicable law; 

  
 -11- 

 (vii) comply with all applicable rules and regulations of the Commission, and
make available to its security holders, as soon as reasonably practicable, an earning statement covering a period of at least twelve months, beginning with the first month of the first fiscal quarter after the effective date of such Registration
Statement, which earning statement shall satisfy the provisions of Section 11(a) of the Securities Act; 
 (viii) in the
case of a Public Offering, use all reasonable efforts to facilitate the distribution and sale of any Registrable Securities to be offered pursuant to this Agreement, including without limitation, by causing appropriate officers of the Company to
attend any “road shows” and analyst presentations and otherwise use commercially reasonable efforts to cooperate as requested by the underwriters or any Holder of Registrable Securities in the offering, marketing or selling of the
Registrable Securities; 
 (ix) cause all such shares of Common Stock and Underlying Shares registered pursuant hereto to be
listed on the securities exchange or quoted on the interdealer quotation system on which the Common Stock is listed or quoted, if such listing or quotation is then permitted under the rules of such exchange or quotation system, and provide a
transfer agent, registrar and CUSIP number for such Registrable Securities no later than the effective date of such Registration Statement; and 

(x) issue to any underwriter to which any Holder of Registrable Securities may sell such Registrable Securities in connection
with any such registration (and to any direct or indirect transferee of any such underwriter) certificates evidencing shares of Common Stock [or Preferred Stock], as applicable, without restrictive legends (subject to each Holder and/or underwriter
providing any customary certificates relating to the distribution or re-legending of Registrable Securities as appropriate). 
 The Company
may require each seller of Registrable Securities as to which any registration is being effected to furnish the Company with such information regarding such seller and the distribution of such Registrable Securities as the Company may from time to
time reasonably request in writing and as shall be required by applicable law or by the Commission in connection therewith. The Company shall have no obligation to have a Registration Statement declared effective or incur costs in connection
therewith until the seller of such Registrable Securities provides such information to the Company; provided, however, that if the applicable Registration Statement is a resale shelf Registration Statement filed pursuant to Rule 415 under the
Securities Act, the Company shall have the right to exclude such seller from the table of selling stockholders set forth in such Registration Statement pending receipt of such information but not to delay the preparation, filing or declaration of
the effectiveness of such Registration Statement to the extent that such Registration Statement is for the benefit of other selling stockholders and such other selling stockholder(s) caused the Company to file such Registration Statement. 

  
 -12- 

 (b) If requested by the underwriters for any Public Offering of Registrable Securities on behalf
of a Holder or Holders of Registrable Securities pursuant to a registration under Section 2.01 or 2.02 hereof, the Company and each such Holder of Registrable Securities will enter into and perform their respective obligations under an
underwriting agreement with such underwriters for such offering, such agreement to contain such representations and warranties by the Company and such Holders and such other terms and conditions as are customarily contained in underwriting
agreements with respect to secondary distributions, including, without limitation, indemnities to the effect and to the extent provided in Sections 2.06 and 2.07 hereof and delivery of opinions of counsel and accountant letters. 

(c) If any registration pursuant to Section 2.01 or 2.02 hereof shall be in connection with an underwritten Public Offering, each Holder
that includes Registrable Securities in such Public Offering agrees, if so required by the managing underwriter(s), not to effect any public sale or distribution (including any sale pursuant to Rule 144) of Equity Securities (other than as part of
such underwritten Public Offering) within ten days prior to or 90 days after (i) the effective date of the Registration Statement with respect to such underwritten Public Offering, or (ii) in the event of a shelf Registration Statement,
the consummation of an underwritten takedown; provided, however, that the 90 day period referred to in this Section 2.04(c) may be extended to up to 180 days upon the managing underwriter’s or underwriters’ reasonable request. 

(d) The Company agrees, if so required by the managing underwriter(s) in connection with an underwritten Public Offering of Registrable
Securities pursuant to Section 2.01 or 2.02, not to effect any public or private sale or distribution of any of its Equity Interests (other than as part of such underwritten Public Offering), including a sale pursuant to Regulation D under the
Securities Act (or Section 4(2) thereof), within ten days prior to or 90 days after (i) the effective date of the Registration Statement with respect to such underwritten Public Offering, or (ii) in the event of a shelf Registration
Statement, the consummation of an underwritten takedown, except in connection with any equity incentive plan, agreement, bonus, award, stock purchase plan, stock option plan or other stock arrangement registered on Form S-8 or an acquisition, merger
or exchange offer; provided, however, that the 90-day period referred to in this Section 2.04(d) may be extended to up to 180 days upon the managing underwriter’s or underwriters’ reasonable request. 

(e) It is understood that in any underwritten offering of Registrable Securities, in addition to the shares (the “Initial
Shares”) the underwriters have committed to purchase, the underwriting agreement may grant the underwriters an option to purchase a number of additional shares (the “Overallotment Option Shares”) equal to up to 15% of the
Initial Shares (or such other maximum amount as FINRA may then permit), solely to cover over-allotments. Shares of Common Stock proposed to be sold by the Company and the Holders of Registrable Securities[, and shares of Preferred Stock proposed to
be sold by the Investors], shall be allocated between Initial Shares and Overallotment Option Shares as agreed or, in the absence of agreement, pursuant to Sections 2.01 or 2.02 hereof. 

(f) No Holder of Registrable Securities may participate in any Public Offering hereunder unless it (i) agrees to sell its Registrable
Securities on the basis provided in any underwriting arrangements approved by the Persons entitled hereunder to approve such arrangements, and (ii) completes and executes all questionnaires, powers of attorney, indemnities, underwriting
agreements and other documents reasonably required under the terms of such underwriting arrangements and this Article II.

 Section 2.05 Preparation; Reasonable Investigation.  

In connection with the preparation and filing of each Registration Statement registering Registrable Securities under the Securities Act, the
Company will give the Holders on whose behalf such Registrable Securities are to be so registered and their underwriters, if any, and their respective counsel and accountants, the opportunity to participate in the preparation of such Registration
Statement, each Prospectus included therein or filed with the Commission, and each amendment thereof or supplement thereto, and will give each of them such access to its books and records and such opportunities to discuss the business of the Company
with its officers and the independent public accountants who have issued a report on its financial statements as shall be reasonably necessary, in the opinion of such Holders and such underwriters or their respective counsel, to conduct a reasonable
investigation within the meaning of the Securities Act. 
 Section 2.06 Indemnification.  

(a) In the case of any Registration Statement filed under the Securities Act pursuant to Section 2.01, 2.02 or 2.12, the Company will
indemnify and hold harmless the seller of any Registrable Securities covered by such Registration Statement, its directors, officers and employees, each other Person who participates as an underwriter in the offering or sale of such Registrable
Securities, each officer, director and employee of each such underwriter, and each other Person, if any, who controls such seller, or each officer, director and employee of such seller, or such underwriter, or each officer, director and employee of
such underwriter, within the meaning of Section 15 of the Securities Act or Section 20(a) of the Exchange Act, against any losses, claims, damages, liabilities and expenses, joint or several, to which any such Person may become subject
under the Securities Act or otherwise, insofar as such losses, claims, damages, liabilities or expenses (or actions or proceedings in respect thereof) arise out of or are based upon (i) any untrue statement or alleged untrue statement of a
material fact in any Registration Statement (including any document incorporated by reference therein) under which the Registrable Securities were registered under the Securities Act, or any Prospectus or issuer free writing prospectus or any
amendment or supplement thereto, or in any filing made in connection with the qualification of the offering under the securities or other “blue sky” laws of any jurisdiction in which Registrable Securities are offered, or the omission or
alleged omission to state a material fact required to be stated therein or necessary to make the statements therein not misleading, or (ii) any violation or alleged violation by the Company of the Securities Act, the Exchange Act or other
federal or state law or any rule or regulation promulgated under the Securities Act, the Exchange Act or other federal or state law; and the Company will reimburse each such Person for any legal or any other expenses reasonably incurred by them in
connection with investigating or defending any such loss, claim, damage, liability or expense; provided, however, that the Company shall not be liable in any such case to the extent that any such loss, claim, damage, liability or
expense (or action or proceeding in respect thereof) arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in such Registration Statement, Prospectus, issuer free writing prospectus or
blue sky filing or any amendment or supplement thereto in reliance upon and in conformity with written 

  
 -14- 

 
information furnished to the Company for use in the preparation thereof by such seller, underwriter or non-selling controlling Person, as the case may be. Such indemnity shall remain in full
force and effect regardless of any investigation made by or on behalf of such Person and shall survive the transfer of such securities by such seller. 

(b) The Company may require, as a condition to including any Registrable Securities in any Registration Statement filed pursuant to this
Article II, that the Company shall have received an undertaking reasonably satisfactory to it from (i) the prospective seller of such Registrable Securities to indemnify and hold harmless (in the same manner and to the same extent as set forth
in Section 2.06(a) hereof, except that any such prospective seller shall not in any event be liable to the Company pursuant thereto for an amount in excess of the net proceeds of the sale of such prospective seller’s Registrable
Securities) the Company, each officer, director and employee of the Company, each underwriter of such securities, each officer, director and employee of each such underwriter and each other Person, if any, who controls the Company or any such
underwriter or any officer, director or employee thereof within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, and (ii) each such underwriter of such securities to indemnify and hold harmless (in
the same manner and to the same extent as set forth in Section 2.06(a) hereof) the Company, each officer, director and employee of the Company, each prospective seller, each officer, director and employee of each prospective seller and each
other Person, if any, who controls the Company or any prospective seller or any officer, director or employee thereof within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, but in each case only with
respect to any statement in or omission from such Registration Statement, any Prospectus included therein, or any amendment or supplement thereto if such statement or omission was made in reliance upon and in conformity with written information
furnished by such prospective seller or such underwriter, as the case may be, to the Company for use in the preparation of such Registration Statement, Prospectus, amendment or supplement; provided, however, that notwithstanding anything in this
Agreement to the contrary, the indemnity agreement contained in this subsection 2.06(b) shall not apply to amounts paid in settlement of any such loss, claim, damage, liability or expense (or action or proceeding in respect thereof) if such
settlement is effected without the consent of the indemnifying party; provided that in no event shall any indemnity under this subsection 2.06(b) exceed the net proceeds from the offering received by such indemnifying party. Such indemnity shall
remain in full force and effect regardless of any investigation made by the indemnified party and shall survive the transfer of such securities by such seller. 

(c) Promptly after receipt by an indemnified party of notice of the commencement of any action or proceeding (including any investigation by
any governmental authority) involving a claim referred to in Section 2.06(a) or (b) hereof, such indemnified party will, if a claim in respect thereof is to be made against an indemnifying party, give written notice to the latter of the
commencement of such action; provided, however, that the failure of any indemnified party to give notice as provided herein shall not relieve the indemnifying party of its obligations under the preceding provisions of this Section 2.06, except
to the extent that the indemnifying party is actually prejudiced by such failure to give notice. In case any such action is brought against an indemnified party, unless in such indemnified party’s reasonable judgment a conflict of interest
between such indemnified and indemnifying parties may exist in respect of such claim (in which case, the indemnifying party shall not be liable for the fees and expenses of 

  
 -15- 

 
more than one (1) counsel for all sellers of Registrable Securities, or more than one counsel for the underwriters in connection with any one (1) action or separate but similar or
related actions), the indemnifying party will be entitled to participate in and to assume the defense thereof, jointly with any other indemnifying party similarly notified, to the extent that it may wish with counsel reasonably satisfactory to such
indemnified party, and after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party will not be liable to such indemnified party for any legal or other expenses
subsequently incurred by the latter in connection with the defense thereof. 
 (d) The indemnity provided for hereunder shall not inure to
the benefit of any indemnified party to the extent that such indemnified party failed to comply with the applicable prospectus delivery requirements of the Securities Act as then applicable to the person asserting the loss, claim, damage or
liability for which indemnity is sought. 
 (e) The right to indemnification under this Section 2.06 shall survive indefinitely. 

Section 2.07 Contribution.  

(a) If the indemnification provided for in Section 2.06 is unavailable to the indemnified parties in respect of any losses, claims,
damages, liabilities or expenses referred to therein, then each indemnifying party shall contribute to the amounts paid or payable by such indemnified party as a result of such losses, claims, damages, liabilities or expenses (i) as among the
Company and each of the selling Holders of Registrable Securities covered by a Registration Statement, on the one hand, and the underwriters, on the other, in such proportion as is appropriate to reflect the relative benefits received by the Company
and each such selling Holder, on the one hand, and the underwriters, on the other, from the offering of the Registrable Securities, or if such allocation is not permitted by applicable law, in such proportion as is appropriate to reflect not only
the relative benefits but also the relative fault of the Company and each such selling Holder, on the one hand, and of the underwriters, on the other, in connection with the statements or omissions that resulted in such losses, claims, damages or
liabilities, as well as any other relevant equitable considerations, and (ii) as between the Company, on the one hand, and each selling Holder of Registrable Securities covered by a Registration Statement, on the other, in such proportion as is
appropriate to reflect the relative fault of the Company and of each such selling Holder in connection with such statements or omissions, as well as any other relevant equitable considerations. The relative benefits received by the Company and each
such selling Holder, on the one hand, and the underwriters, on the other, shall be deemed to be in the same proportion as the total proceeds from the offering (net of underwriting discounts and commissions but before deducting expenses) received by
the Company and each such selling Holder bears to the total underwriting discounts and commissions received by the underwriters. The relative fault of the Company and any selling Holder, on the one hand, and of the underwriters, on the other, shall
be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company and any selling Holder
or by the underwriters. The relative fault of the Company, on the one hand, and each such selling Holder, on the other, shall be determined by reference to, among other things, whether the untrue or 

  
 -16- 

 
alleged untrue statement of a material fact relates to information supplied by the Company or any such selling Holder, and the parties’ (including as between selling Holders) relative
intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. 
 (b) The Company and the Holders
of Registrable Securities agree that it would not be just and equitable if contribution pursuant to this Section 2.07 were determined by pro rata allocation (even if the underwriters were treated as one entity for such purpose) or by any other
method of allocation that does not take account of the equitable considerations referred to in the preceding paragraph. The amount paid or payable by an indemnified party as a result of the losses, claims, damages, liabilities or expenses referred
to in the preceding paragraph shall be deemed to include, subject to the limitations set forth above, 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 Section 2.07, no underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Registrable Securities underwritten by it and offered and distributed
to the public exceeds the amount of any damages that such underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission, and no Holder of Registrable Securities shall be required
to contribute any amount in excess of the amount by which the total price at which the Registrable Securities of such Holder were offered to the public exceeds the amount of any damages that such Holder has otherwise been required to pay by reason
of such untrue or alleged untrue statement or omission or alleged omission. 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 obligation of each Holder of Registrable Securities to contribute pursuant to this Section 2.07 is several in the proportion that the proceeds of the offering received by such Holder bears to
the total proceeds of the offering received by all the Holders and not joint. 
 Section 2.08 Nominees of Beneficial Owners. 

 In the event that any Registrable Securities are held by a nominee for the Beneficial Owner thereof, the Beneficial Owner thereof may, at
its election, be treated as the Holder of such Registrable Securities for purposes of any request or other action by any holder of Registrable Securities pursuant to this Agreement or any determination of any number or percentage of shares of
Registrable Securities held by any Holder or Holders of Registrable Securities contemplated by this Agreement. If the Beneficial Owner of any Registrable Securities so elects, the Company may require assurances reasonably satisfactory to it of such
Beneficial Owner’s ownership of such Registrable Securities. 
 Section 2.09 Rule 144. 

The Company shall use all commercially reasonable efforts to take all actions necessary to comply with the filing requirements described in
Rule 144(c)(1) or any successor thereto so as to enable the Holders to sell Registrable Securities without registration under the Securities Act. Upon the written request of any Holder, the Company will deliver to such Holder a written statement as
to whether it has complied with the filing requirements under Rule 144(c)(1) or any successor thereto. 

  
 -17- 

 Section 2.10 Information Blackout. 

(a) Upon written notice from the Company to the Holders that the Company has determined in good faith that the sale of Registrable Securities
pursuant to a Registration Statement would require disclosure of non-public material information not otherwise required to be disclosed under applicable law (A) which disclosure would have a material adverse effect on the Company or
(B) relating to a material business transaction involving the Company (an “Information Blackout”), the Company may postpone the effectiveness of any Registration Statement required hereunder and, if such Registration Statement
has become effective, the Company shall not be required to maintain the effectiveness of such Registration Statement and all Holders shall suspend sales of Registrable Securities pursuant to such Registration Statement, in each case, until the
earlier of: 
 (i) sixty (60) days after the Company makes such good faith determination, and 

(ii) such time as the Company notifies the Holders that such material information has been disclosed to the public or has ceased to be
material or that sales pursuant to such Registration Statement may otherwise be resumed (the number of days from such notice from the Company until the day when the Information Blackout terminates hereunder is hereinafter called a “Blackout
Period”). 
 (b) Any delivery by the Company of notice of an Information Blackout during the sixty (60) days immediately
following effectiveness of any Registration Statement effected pursuant to Section 2.01 or 2.12 hereof shall give the Holders of a majority in aggregate amount of Registrable Securities being sold the right, by written notice to the Company
within twenty (20) Business Days after the end of such Blackout Period, to cancel such registration. 
 (c) Notwithstanding the
foregoing, there shall be no more than two (2) Information Blackouts during any calendar year and no Blackout Period shall continue for more than forty-five (45) consecutive days. 

(d) Notwithstanding the foregoing, the Company shall not exercise its rights under Section 2.10(a) unless it has applied the same
information blackout restriction to all other holders of registration rights. 
 Section 2.11 Restriction on Company Grants of
Subsequent Registration Rights. 
 The Company agrees that, without the prior written consent of the Holders of a majority of the
Outstanding Registrable Securities, it shall not enter into any agreement with the holder or prospective holder of any securities of the Company that would grant such holder or prospective holder any registration rights. 

Section 2.12 Investor Demand Rights. Following the Effective Date, the Company shall, as soon as commercially reasonable, but in
no event later than forty five (45) days after the Effective Date, file a Registration Statement under the Securities Act on any permitted form that qualifies, and is available for, the resale of the Registrable Securities held by the Investors
(the 

  
 -18- 

 
“Investor Demand Registration”). The Company shall use its reasonable best efforts to (i) cause such Investor Demand Registration to become effective as promptly thereafter
as practicable, but in any event not later than one hundred twenty (120) days after the Effective Date if the Company receives comments to the Investor Demand Registration from the Commission (“SEC Comments”) or ninety
(90) days after the Effective Date if the Company does not receive SEC Comments and (ii) obtain acceleration of the effective date of the Registration Statement relating to such registration. 

ARTICLE III 
 TRANSFERS

 Section 3.01 Transfer of Rights 

(a) A Holder may transfer all or any portion of its rights with respect to the Registrable Securities under this Agreement to any Person (each,
a “Transferee”), and any such Transferee may likewise transfer all or any portion of the rights it acquires with respect to the Registrable Securities to a subsequent Transferee. A Holder and any Transferee who transfers securities
to another Person is referred to herein as a “Transferring Holder.” 
 (b) Any such transfer of rights under this Agreement
will be effective upon receipt by the Company of (i) written notice from such Transferring Holder stating the name and address of any Transferee and identifying the number of Registrable Securities with respect to which rights under this
Agreement are being transferred and the nature of the rights so transferred, and (ii) a written agreement from the Transferee to be bound by the terms of this Agreement, upon which such Transferee will be deemed to be a party hereto and have
the rights and obligations of the Transferring Holder hereunder with respect to the Registrable Securities transferred. 
 (c) In the event
the Company engages in a merger or consolidation in which the shares of Common Stock or Preferred Stock, as applicable, are converted into securities of another company, appropriate arrangements will be made so that the registration rights provided
under this Agreement continue to be provided to Holders by the issuer of such securities. To the extent such new issuer, or any other company acquired by the Company in a merger or consolidation, was bound by registration rights obligations that
would conflict with the provisions of this Agreement, the Company will use its reasonable best efforts to modify any such “inherited” registration rights obligations so as not to interfere in any material respects with the rights provided
under this Agreement, unless otherwise agreed by the Holders. 
 Section 3.02 In-Kind Distributions. 

If a Holder seeks to effectuate an in-kind distribution, a transfer or an assignment of all or part of its shares of Common Stock or Preferred
Stock to its direct or indirect equityholders or any Affiliates thereof, then the Company will cooperate with such Holder and the Company’s transfer agent to facilitate such transaction in the manner reasonably requested by such Holder.

The parties hereto agree that irreparable harm would occur in the event that any of the agreements and provisions of this Agreement were not

quantifying the amount of damage that will be suffered by the parties hereto in the event that this Agreement is not performed in accordance with its terms or conditions or is otherwise breached. It is accordingly hereby agreed that the parties
hereto shall be entitled to an injunction or injunctions to restrain, enjoin and prevent breaches of this Agreement by the other parties and to enforce specifically the terms and provisions hereof in any court of the United States or any state
having jurisdiction, such remedy being in addition to and not in lieu of, any other rights and remedies to which the other parties are entitled to at law or in equity.
